Abstract
The snowboard binding consist of a sole part (6) integrated in the snowboard boot (1) and a first binding element (7) cooperating with it and continuously connected to the snowboard (S). The sole part (6) has two spring-loaded pine 9 projecting laterally out of the sole part and capable of engaging with an opening (8) of the first binding element (7). The pins can be retracted with a device (12) attached to the snowboard boot and thus the binding can be opened.
Description
SNOWBOARD BINDING
Description The invention pertains to a snowboard binding.
Such a binding was publicly exhibited at the ISPO
[tradefair] in Munich on February 24, 1994. This binding had a front :stirrup rigidly connected to the snowboard which reached over the front part of the boot sole and thus held i_t: in place. A pin running transversely to the boot's longitudinal axis was inserted through the' heel-side part of the boot sole and projected about 5-10 mm from the boot sole at both sides. A heel element to be screwed firmly in place on the snowboard consi:>ted of two lateral cheeks running parallel and projecting vertically from the snowboard surface; these had a vertically oriented slot, into which the part of tree pin projected out of the shoe could be introduced. A catch device on the lateral cheeks had the form of a hook which was pushed back during introduction of the pins into the slots and thus opened them, while with the pin parts completely housed in the slots it snapped into locking position and thus engaged the pins. 1:n order to open the binding, a lever on one of the lateral cheeks had to be operated, by which means the ~~t:irrups could be moved into the opening position anc~ the heel part of the shoe could be moved from the binding. This binding exhibited at the ISPO is also described in DE 4,311,630 A1, published subsequently.
AT 351,419 shows a ski binding with a shell nearly completely encompas~~ing the skier's boot that can be folded open and is fastened tightly to the surface of the ski. A shell part covering the front part of the foot and one covering the front side of the shin are articulated to pivot: at the front toe of the shell and can be pivoted between an opening or insertion position and a clo:~ed position. In the closed position the two aforementioned shell parts are locked in place by spring-loaded catch pine on the stationary shell parts. The spring-loaded bolts can be brought into an unlocked position by cables in order to allow a release in case of excessive stress or an opening for stepping out. In the latter case, the skier can operate the cables by a lever housed on the stationary shell part.
This ie thus a shell binding which ie intended to allow the use of very soft and therefore comfortable ski boots.
DE 2,556,817 A1 shows a ski binding with a binding plate that is attached by spring-loaded cables to the surface of the e,ki. Then a release force is exceeded, this plate can be removed a distance preset by the length of the cables from the surface of the ski. A recess is provided for this plate in the sole of the ski boot. A catch mechanism ie present in the interior of the plate and allows the locking of the plate in the recess of the ski boot sole.
In case of a release of the binding due to excessive force, therefore, the boot is released from the ski together with the plate. For opening, that is, stepping out, the boat must be detached from the plate. An unlocking mechanism that can be operated by the skier either manually or with a ski pole is provided on the plate for this purpose.
Another eo-called f'step-in" binding, in which skier need not operate any locking elements when stepping into the binding, is described in DE 4,106,401 A1. The boot is held by two ordinary stirrups, a front and a heel stirrup. The heel stirrup, however, is articulated to a tread element which is in turn attached eo as to be able to pivot to connection elements that are tightly connected to the snowboard. Herein is also attached a locking mechanism which grips the tread element when it is pressed completely down and holds it locked in position. In order to open the binding the skier must bend down and operate this locking mechanism by hand in order to open it. If there is snow or ice beneath the shoe sole, a locking of the tread element is not assured, since this snow or ice would make contact with the binding, before the tread element was pushed all the way down. Thus this binding is only functional to a limited extent.
DE 2,511,332 A1 shows a ski binding in which part of the binding ie likewise integrated into the heel of the ski boot. Two spring-loaded spherical-head bolts project laterally from the heel part of the boot sole and engage in matching recesses rigidly attached to the ski at the aides.
This a self-releasing safety binding which opens when a predetermined force i~ exceeded. This force is determined by the springs pushing the two bolts outward as well as by the shape of the spherical heads of these bolts and by the shape of the recesses for these spherical heads.
The regular opening of the binding is done at the front jaw holding the toe of the boot, while the heel attachment can only be overcome by tipping the foot to overcome the spring force. For emergencies in which the skier might be injured, it is also provided that the elements housing the bolts can be rotated eo that a groove located in them allows the boot to be pulled up and out of the binding.
DE 2,200, 056 A1 describes an additional release binding for skies. There too is provided a bolt pushed transversely through the boot sole; it engages with a hook-shaped, spring-loaded locking element. The entire locking element is pushed backward in the axial direction of the ski to open the binding; this is accomplished by operating a lever mounted on the ski.
DE 3, 141,425 A1 shows a safety binding for skis in which spring-loaded pine are attached to the boot and 21487~~
matching receptacle devices are attached to the ski. Here too, a mechanism fastened to the ski ie operated to open the binding.
Finally, DE 2,809,018 A1 shows a ski binding system consisting of ski boot and releasing binding elements, with a plate that projects beyond the boot incorporated into the sole or providing two bolts, somewhat separated, and pivoting hooks on the gki that grip laterally over this plate or the two bolts.
For snowboard bindings, many participants have long desired a so-called step-in binding, that is, a binding one could simply step into like a ski binding, without the snowboarder having to bend down to operate parts of the binding, such as locking etirrups_ on the other hand, safety bindings that would permit complete release of the shoe from the snowboard in case of excessive force applied are still problematic for enowboards, since the resulting safety problems for participants and bystanders have not yet been satisfactorily solved, despite numerous proposals.
Finally, the very serious problem of space also comes up in regard to snowboard bindings. The snowboarder is standing essentially transverse to the travel direction of the board, which means in practice that the angle between shoe longitudinal axis and gnowboard longitudinal axis is between 45~ and 90°, with some enowboarders even orienting their rear foot backwards, that is, at an angle of greater than 90° with respect to the direction of travel. Since snowboards, particularly the so-called alpine boards for snowboardere on prepared slopes, are becoming narrower and narrower, the toe of the boot and the heel of the ski boot are already projecting out over the contour of the snowboard. The principle can therefore be established that a snowboard binding must not project beyond the toe or heel of the boot, since this could lead to projecting binding parts touching the snow when the board is turned on edge. Fox- this reason, conventional ski bindings that have t:he step-in function are not suitable for snowbo~irds .
The initially mentioned step-in binding for snowboards, publicly announced at the ISPO fair in February 1994, avoids these disadvantages. Its comfort of use leaves something to be desired, however, since the snowboarder must: bend over to open the binding in order to operate a z~elease lever connected directly to the board's surface. The design of this release lever is also rather elaborate technically, and it tends to raise the weight. This runs contrary to the trend towards snowboards rind snow board bindings that are as light as possible.
The problem o:f t:he invention is therefore to improve the snowboaz~d binding of the type mentioned initially in such a way that the comfort of the binding is further improved and which nevertheless meets the requirements for light weight, functional security and costs as low as pos~~ible .
This problem i~~ solved by the snowboard binding according to the present invention.
The fundamental. and essential idea of the invention lies in moving essential parts of the binding and especially the 7_ocking device into the snowboard boots, which not on7_y enhances comfort when stepping out of the binding, :~o that the snowboarder need no longer bend when stepping out of the binding, but also achieves the advantages below. The binding parts to be fastened to the snowboard are light and insensitive to icing. The more expensive locking elements, also more subject to icing, axe located inside the boot or boot sole and are therefore better protected against icing ~14~'~4~
and can thus be combined with other enowboards that use the same binding parts_ An essential aspect of the invention lies in the fact that not only stepping into but also stepping out of the binding is considerably eased, so that a so-called "step-out" function is achieved. Finally it must also be especially emphasized that, after opening, the binding automatically returns to its initial position and is ready to be stepped into again without any active effort on the snowboarders part. This initial position is synonymous with the closed position, that is to says the locking elements have the same rest position in a completely open and a completely closed binding. Thus it ie impossible for the locking device to remain in a position, due to ice, perhaps, in which the binding might open inadvertently.
Additional advantages of the invention are explained in the description below.
The invention is described below on the basis of embodiment examples in conjunction with the drawings. These show:

Although the invention is described in most embodiment examples (except Figure 7) in connection with the use of a front stirrup, it should be pointed out that in all embodiment examples the invention can also operate without such a front stirrup.
In this case the shoe-side binding 7a a ' part, as.deecribed in greater detail in conjunction with Figure 14, is mounted roughly in the middle of the shoe and it is assured with base blocks that the tip of the Bole and.
the heel are positioned at the correct height with regard to the enowboard surface. In this case, it ie also possible to omit a binding base plate. However, if it is desired that the fastening of the snowboard-aide binding part to the snowboard should be more changeable, for instance, for adjusting the step size between the two bindings and/or the angle of rotation of the binding in regard to the longitudinal axis of the snowboard, then a base plate may be used in this variant as well.
Figure 1 shows a side view of a snowboard boot 1 just prior to its locked pasition with a binding element 2 to be fastened to the enowboard 5. This binding element 2 consists of a base plate 3 to be fastened to the snowboard, which can be done in a,variety of ways. As is common with so-called plate bindings, the binding element has a front stirrup 4 which grips over a sole projection 5 of the snowboard boot 1 and thus holds the front end of the snowboard boot in place. A second binding element 6, configured here as the heel part 6 of the snowboard boot 1, contains essential parts of the binding that cooperate with a heel element 7 mounted on the binding element 2.
In a rough sketch, this heel element 7 has two parallel lateral cheeks 7',7", the spacing of which is only slightly greater than the width of the heel part 6 of the snowboard boot 1. Each lateral cheek 7',7" has an opening 8 into which a spring-loaded pin 9 projecting laterally out of the heel part 5 can engage respectively.
For the secure fastening of the snowboard boot it ie necessary that it be pressed forward with a minimal force against the front stirrup 4. This therefore implies that ~14~~42 the spacing between the front stirrup 4 and the pin 9 or the opening 8 which'housee it'hae a certain maximum length in order to produce thie-force. When stepping into the binding the boot is normally pushed against the front stirrup 4 with a lowered front foot and a somewhat elevated heel, which does not produce sufficient pressing force, however. Then the pins 9 and openings 8 would not be sufficiently aligned when the heel goes down. In order to achieve this alignment , a downward incline 10 ie provided on each of the lateral cheeks 7',7"; these cooperate with laterally protruding projections 11 and press the boot ae a whole forward when the heel ie pressed down. The spacing between the pin 9 and the projection 11 corresponds exactly to the spacing between the opening 8 and the elope 1a, eo that ae the heel ie pressed down, the Spring-loaded pin 9 ie certainly guided past the opening 8 and then can engage in it. At the same time, the necessary force pushing the boot forward ie produced, which presses the boot toe firmly against the front stirrup 4.
When the pins 9 are engaged in the openings 8, the boot ie firmly attached to the enowboard and can no longer come loose inadvertently. To open the binding, the two pins 9 are pressed or drawn together inwardly in this embodiment example, so that they come loose from the openings 8, which means that the shoe can initially be raised somewhat by the heel and then removed from the binding. In order to displace the pine 9 in the manner described, a cable 12 ie provided, which ie led upward on the back side of the boot 1 to the shaft and held in place there by a belt 13. A grip loop 14 is placed on the cable 12. If the cable 12 ie pulled, then, ae will become clearer in the description below, the two pine 9 are pulled inward, which opens the binding.

A peculiarity of the invention is therefore the fact that the opening or unlocking of the binding is done on the boot and not on the part of the binding that ie fastened to the snowboard or ski, ae in previously known snowboard or ski bindings. This has the advantage, among others, that the snowboarder need not bend down to the binding or use ski poles {not present in snowboarding anyway) for assistance, ae is the case with most ski bindings. If desired, the snowboarder can extend the length of the cables indefinitely, perhaps even up to belt height. An additional advantage is that essential components of the binding are integrated into the boot. Thus the binding element 2 which is constantly connected to the enowboard can be designed to be very simple and very economical, so that a snowboarder who owns several snowboards need only buy the more expensive binding parts once, together with the boot whereas only the more economical binding element 2 need be purchased for all snowboards.
It should also be emphasized that the heel part 6, which contains essential components of the binding, can also be manufactured as a separate part and subsequently screwed or glued on onto a boot or fastened in some other manner.
Figure 2 shows a side view of heel-side components of the binding in the locked state, that is, in which the pin 9 ie engaged with the opening 8. Also clearly a~een here ie the effect of the incline 10 and the projection 11, which cooperate to guide the boot while the heel is being pressed down such that the pin 9 and the opening 8 are oriented towards one another. It ie recognized better from Figure 2 that the lateral cheek 7 is guided so it can be displaced on a mounting block 15 attached to the base plate 3, which means that the binding as a whole can be matched to the shoe size. A setscrew 16 is provided for displacing the lateral ~~~~~~z cheeks.
The lateral cheeks have a dimple 17 at their upper end, which makes stepping into the binding easier, because with light pressure applied to the heel, the pin 9 moves to the lowest point of the dimple 17, which means that the projection 11 is then in the proper position with respect to the incline 10. It ie also clearly recognizable from Figure 2 that the lower aide of the shoe sole of the heel part is not yet in contact with any binding elements such ae the mounting block 15, but instead maintains a distance from it.
Thus a secure locking of the binding occurs even if there is snow underneath the boot sole. Since the heel ie supposed to be somewhat higher than the toe of the boot for snowbaards anyway, with the invention one can dispense with the wedge underlay otherwise used for the heel part.
Clearly recognizable in Figure 3 is the position of the two lateral cheeks 7',7", which stick out vertically from the snowboard parallel to one another and house the heel part of the snowbaard boot between them. Both lateral cheeks 7',7" are connected together by a connection element 18 that,liee on the mounting block 15. Both lateral cheeks 7',7" are extended in the direction of the base plate 3 beyond the connection element 18 and grip over the mounting block. l5 with inward-directed arms 19',19". Thus the heel element 7 ie firmly on the mounting block 15 and can be displaced only in the longitudinal direction of the snowboard. For this purpose, the mounting block 15 has an opening 20 for housing the setgcrew 16 as well ae a slot, not illustrated, which opens the opening 20 to the upper side of the mounting block 15, eo that a threaded part gnat shown) connected to the connection element 18 is in connection with the setecrew 16, with which a longitudinal adjustment of the heel element 7 is possible.
'' 2148'~4~
It is also easily recognizable from Figure 3 that the lateral cheeks 7',7" have an incline 21',21"; respectively, above the openings 8 which insures that the spring-loaded pin ie pressed inward into the heel part 6 of the shoe.
In order to design the effect of the dimple 17 to be more efficient, it is practical to insure that the bolts 9 are only pressed inward in the position in which they make contact with their cylindrical part on the upper side of the lateral cheeks. For this purpose an additional dimple 22 running parallel to the longitudinal extension of the inclines 7',7" ie provided in the vicinity of the inclines ' 21',21"; the dimple ie best recognized from Figure 3a and has a greater angle of inclination with respect to a central axis 23 perpendicular to the snowboard than the incline 21'.
Only when the bolt 9 ie in the deepest point of the dimple 17 does its free end make contact with the wall of the dimple 22, so that it is pressed inward when the heel is pressed downward.
It is also recognizable from Figure 3 that the central axis 24 of the openings 8 is spaced away from the upper side of the connection element 18, with this spacing being greater than the corresponding spacing between the midpoint of the pin 8 and the bottom aide of the sale of the heel part 6 of the snowboard boot 1. In that way the functioning of the binding ie not impaired by snow or ice on the sole of the snowboard boot_ Figure 4 shows a plan view of the inside of the heel part 5 of the snowboard boot 1. This heel part has a cavity 25 in which the pine 9,9' and the mechanism for displacing them are accommodated. Along an axis 26 that coincides with the axis 24 of Figure 3, the heel part 6 has two opposing aligned openings in which the guide bushings 27,27' are inset and in which the pins 9,9' respectively are guided so -- ~14$7~~
se to be displaceable. Both pins are pressed outward by a spring 28, until here in the embodiment example of Figure 4 the pins 9'9', directly connected at their inside end faces by the spring 28, abut against a atop formed here by the guide bushings 27.
The spring 28 ie constituted here se a U-shaped stirrup. The length of the pins 9,9' is dimensioned such that the pins 9,9' only protrude laterally by a predetermined amount' for instance 5-1d mm, from the contour of the heel part 6_ The ends of the pine 9,9' protruding outward are rounded off in order to ease the insertion of the pine between the two lateral cheeks 7',7". The radius of curvature of this rounding ie equal to half the diameter of the otherwise cylindrical pins, so that the points of the pine protruding outward form a hemisphere.
A tensile element 29,29', which may be a plastic or metal cable in the simplest example, ie formed on the pins 9,9', respectively, in order to open the binding. These two tensile organs are guided in opposite directions over a deflection stanchion 30 and connected together in a connection element 31, se well se to the cord 12 WhlCh is guided through an opening 30 from the inside of the heel part 6, as illustrated in detail in Figure 1. The cable 12 can also be made of plastic or metal. If one pulls on this cable 12, the tensile force will be directed onto both tensile elements 29,29' and transferred by way of the deflection stanchion 30 to the pins 9'9' eo that the latter are drawn inward along the axis 26 into the heel part 6. If the cable 12 ie once again released, the two pin are pushed outward again by the spring 28_ It can also be easily recognized from Figure 4 that the projections 11,11' stick out roughly just se far se the pine 9,9' from the contour of the heel part 6, which shield the z~~~~~~
pine 9,9' so that the danger of being caught on the pine in ordinary walking is reduced. To this end, the projections 11,11' also have a rounded off shape, an elliptical shape far instance, and thus act as guards to prevent the pins 9,9' from catching on any objects_ The surfaces 33,33' of the projections 9,9' immediately facing the pins 9,9' are shaped essentially smooth and are fitted to the incline 10 (Figure 1).
Finally, it ie also recognizable in Figure 4 that the heel part 5 ie closed off all around and thus can be employed as an aftermarket product for conventional snowboard boots. Naturally it is also possible to integrate the heel part 6 completely into the shell of the snowboard hoot.
The side view in Figure 5 clarifies the position of the spring 28, the tensile element 29 and the cable 12 in the heel part 6 of the snowboard boot 1. The deflection stanchion 30 can be provided as a separate part, but it can also be molded in one piece with the heel part, which generally consists of plastic.
Figure 6 shows another variant of the heel part, differing from the embodiment example of Figures 4 and 5 by the spring and the tensile elements. The spring 28 is constructed here as a coil spring oriented along the axis 26 and pressing against the two pins 9,9'. The two pins 9,9' each have an enlargement 33, 33' respectively at their ends, on which the spring 28 is supported and each of which also supports one arm of a lever 34,34' on the side of the enlargement 33 opposite the spring 28. This can be done on one side _of the pin . The corresponding lever arms can also be constructed as claws that grip the pin on both sides. These arms are bent in a convex shape in order to slide along the enlargement 33 during pivoting of the levers 2148'42 about pivot axis 35,35' respectively. The two other arms of the lever 34,34' are roughly perpendicular to the aforementioned arms and are connected via two short cables 36,36' to cable 12. In the illustration of Figure 5, the cable 12 is being pulled, eo that the two pins 9,9' are roughly in the unlocked position. In the locked position, the two pine 9,9' abut against guide bushings 27,27', which in turn define the limit position of the pins 9,9'.
The variant in Figure 7 likewise works with a coil spring 28 and levers 34,34'. It is distinguished from the embodiment example of Figure 6 in essence only by the shape of the levers and their attachment to the pins 9,9'. The levers 34,34' are connected to the pin here by a slot connection, that ie, the levers 34, 34' each have a slot 37,37', into which a bolt 37' running perpendicular to the axis 26 of pins 9' is inserted. When the levers are pivoted, this bolt 37' slides along the slot 37. Otherwise, the functioning corresponds to the embodiment example of Figure s.
The embodiment example of Figure 8 likewise operates with a coil spring 28 and a rod linkage, which ae a result the desired tensile force is exerted on the pins 9,9'. The pine 9,9' are bent so that the bent arms 38,38' are offset with respect to the axis 26. The free ends of these bent arms 38,38' are connected by slot connections 39,39' to a pivoting lever 40, the pivot axis of which is positioned mirror-symmetrically to the two pins 9,9' on the axis 25.
The cable 12 can either be articulated at one end of the pivoting lever 40 or, depending on the desired exit point for the cable 12, to an additional pivoting lever 42, which ie firmly connected to the pivoting lever 40 and thus transfers the tensile force of the cable 12 to the latter.
In the embodiment example of Figure 9, sections of the 2~.~8'~4~
pine located in the interior of the second binding part 6 are mutually laterally offset and here are pressed outward by a spring (not shown . The mutually overlapping part 42 of the pins has passage openings 43 with inclined sides 44.
Inserted into these passage openings ie a bolt 45 which hoe oppositely oriented ramp inclines 46,47. If the bolt 45 connected to cable 22 ie displaced, then the two pins 9,9' are drawn inward, which opens the binding. The spring with a force tending to press the two pine 9,9' outward can be embodied in a great variety of ways. It may, for instance, attack directly at the bolt 45 as an extension of the central axis and be constructed ae a compression or tension spring. It may also be designed as a strap spring, corresponding to the embodiment example of Figure 4.
Finally, it ie also possible to provide one or two compression springs that act directly on the pine.
In the embodiment example of Figures 10 and 11, one or two pins are attached to the lateral cheeks 7',7", while the locking mechanism has the form of one or two pivoting levers which grip behind the pin or pins_ Figure lOA shows a side view of the heel part 6 of a snowboard boot 1. In the rear sole areas a recess 48 extending inward on both sides, has an inclination 49 in the area pointing towards the sole tip, which ends in a rounding 51 near the lower side 50 of the sole. A locking lever 52,52' ie housed in each of these two cutouts 48, both locking levers 52,52' being fastened to a Gammon rotating shaft 53_ This rotating shaft runs crosswise through the enowboard boot through the cavity 25. Another lever 54, connected to the cable 12, ie attached without rotational play to the rotating shaft 53. Furthermore, a spring, not shown, can be attached to this lever 54 to press the lever 54 and thus the two lacking levers 52,52' opposite the 214~'~4~
tension direction of the cable 12 in the direction of the shoe toe, thus pressing the two locking levers into their locked position. The locking levers 52 are bent in a bow shape and have a flat locking surface 55, which is oriented roughly horizontally in the locked position and firmly contacts the associated pins 9,9' placed on the lateral cheeks 7',7 " . Adjacent to this locking surface 55, the locking lever 52 has an inclined plane 56, which insures during the stepping-in process that the locking levers 52,52' are pivoted backwards into the opening position se soon se the inclined plane 56 touches the pins 9. As soon se the tip of the locking levers elides past the pin 9, the locking levers 52 are pressed forward by spring force into the locking position, and the binding is closed.
4sThen stepping into the binding, the incline 49 serves as a guide surface which, as soon as it makes contact with the pin 9, displaces the boot forwards_ It thus has essentially the same function as the projection 11 with the guide surfaces 33 in the previously described embodiment examples.
The locking levers are well protected in the recesses 48, so that there is no danger that these levers will get caught somewhere during the stepping-in process.
It can be seen even better from Figure lOB how the two pine 9,9' are fastened to the lateral cheeks 7',7" and point inwards at one another. The recess 48 and its protective function for the locking levers 52,52' are also clearly recognizable.
In connection with Figure 10A, it should also be painted out that even in the inside of the boot, the cable 12 can be directed upwards into the boot, running, for instance, between shoe liner and shell. This arrangement is a fundamental possibility with all embodiment examples.
214~'~42 In order for the locking position of the locking levers to be securely fixed in place and not dependent on the force of the spring, it ie practical to arrange the central axis of the of the rotating shaft 53 above the central axis of the pins 9 with the binding closed or even to displace it somewhat towards the boot toe. Forces directed perpendicularly upwards from the enowboard surface would then in the first instance not exert any torque onto the locking levers 52 or, in the case of an axis of the rotating Shaft 53 displaced even further forward, would even produce a torque forcing the locking levers 52 more firmly into the locking position.
In the embodiment example of Figure 11, a pin 9, passing all the way through and connecting the two lateral cheeks 7',7" and only one central locking lever 52, which has the same cross section in the side view of Figure 11A as the two locking levers 52,52' of Figure 10, are used. The boot Bole has a recess 57 opening downwards and ending laterally Figure 11A) in an opening which in turn has an incline 58 on its wall pointing towards the boot toe and, in cooperation with the pin 9, forcing the boot forwards towards the toe. Here too the central locking lever is pressed by a spring, not shown, into the locking position.
Otherwise the function is the same ae in the embodiment example of Figure 10.
In the embodiment example of Figure 12, the pins 9 located in the interior of the second binding part 6 are connected by articulated levers 60,60' to the pivoting lever 40, with the ends of the articulated lever 60,60' each being connected by a pivot joint to the pins 9,9' and the pivoting lever 40. The central axis of the pivoting lever 40 rune perpendicular to the central axis of the pins 9,9'. One central axis of the ~ articulated lever ~. 214~74~
60,60', by contrast, is positioned at an angle of roughly 45° to the central axis of the pivoting lever 40. The two pivoting levers 60,60' are parallel to one another and are each connected to one end of the pivoting lever 40. If the pivoting lever 40 is rotated about its pivot axis 41 (clockwise in Figure 12}, then the articulated levers 60,60' each apply a tensile force to the pins 9,9' and pull them into the interior of the second binding part 6. The tensile element 12 is connected to one end of the pivoting lever 40.
For this purpose, a blind hole 63 and a continuing [smaller]
through-hale 64 are provided on the pivoting lever. The tensile element 12 is threaded through the through-hole 64 and thickened at its end by a knot, a press-on sleeve or the like so that it can no longer be pulled back through the through-hole 64. The thickened end is then arranged to be sunk into the blind hole 63.
In contrast to the previously described embodiment examples, the tensile element 12 runs in the interior of the second binding part 6 roughly at a right angle to the central longitudinal axis of the shoe and ie therefore directed outwards laterally on the boot.
The second binding part 6 is constructed as an injection-molded plastic part, as was possible in principle for the other embodiment examples as well, and can be subsequently screwed onto the sole of a boot. Screw holes 65 are provided for this purpose. In order to be able to accommodate binding parts in this binding element 6, a recess 66 ie provided and houses the individual parts, including the spring 28. This spring is constructed here as a leaf spring bent in a U-shape, supported on the ends of the pins 9,9' projecting into the interior of the binding part, as becomes clearer from the detailed view in Figure 12a.
.....
21~874~
It can also be recognized in Figure 12 that the second binding part 6 has drill holes 70 on both sides through which the tensile element 12 can be led out, since it is fundamentally desirable to lead the tensile element to the outside of the respective boot, that ie on the right side of the right boot and on the left aide of the left boot.
Figure 12a shows an enlarged detail view of a specific aspect of Figure 12, namely, the guiding of the pin 9 through the wall of the second binding part 6. Since a high degree of flexibility regarding the motions of the foot in all directions ie desirable in enowboarding, but moat snowboard boots,in use with plate bindings have a relatively hard outer shell, this flexibility cannot be achieved by the shoe alone. For this reason, the pin 9 is flexibly supported in relation to the second binding part 6, which is rigidly connected to the boot. To this end, the pin 9 is supported so as to be displaceable in a metal easing 69, which is in turn connected to the second binding part 6 by an elastic easing 68. This elastic easing 68 can consist, for instance, of rubber or some other resilient material, such as an elastic plastic. In manufacturing the second binding part 6, the plastic "shell" of which is produced by injection molding technology, it is possible to mold on this flexible easing 68 in a second work step in the same injection molding form, which means that the easing 68 also obtains a very good connection to the binding part 6. Nat only are shocks dampened and absorbed by this resilient supporting of the pine, which absorb the essential forces between the gnowboard and the boot, the boat can also be tilted in an angle of 1-3° perpendicular to the longitudinal direction, which considerably increases comfort in use.
It can also be recognized from Figure 12a how the spring 28 is supported on the pin 9. In the embodiment ~. 21~87~~
example shown here, the latter has a radially projecting collar 67, which, on one hand, serves as a atop that defines the limit position of the bolt and, on the other, supports the spring 28. Here the spring has a drillhole 28' through which projects the interior end of the pin, to which in turn the articulated lever 60 (Figure 12) ie connected by way of the pivot bearing 61. It should be emphasized at this point that the flexible bearing of the pine according to Figure 12a can be applied td the variants of the invention.
Alternative to or in combination with this flexible bearing of the pin, the first binding part 7 can also be flexibly attached to the snowboard, for example by inserting a resilient plate of rubber or flexible plastic between the snowboard surface and the first binding part (as will be explained more closely in connection with Figure 14).
Figure 13 shows a refinement of the invention in which the tensile element 12 for opening the binding ie extended further and is partially integrated into the snowboarder's clothing. The tensile element can thus be led upward to an arbitrary height to suit the comfort of the snowboarder. It has proven practical to guide the tensile organ roughly up to the height of the thigh, where it can be gripped by the Bnowboarder's hand without any bending at all. For this purpose, a loop 13 on upper end of the tensile element 12 ie connected by a snap hook 71 or some other easily operated suspension device to an extension belt 72, preferably guided in the interior of the enowboard pants and only emerging at an opening 76. There the extension belt 72 has another loop 77 that can be gripped by hand. This loop 77 is held in position by an rubber belt 78 fastened, for instance, to the belt of the pants or a loop sewed onto the pants_ Most contemporary enowboard pants have a sleeve 74 that is sewn onto the pants along a seam 75 at the level of the , ~ ~148'~4~
shin and extends partially over the upper part of the boot 1. The extension belt 72 is guided in this area between the pants 73 and the sleeve 74. When the enowboarder puts on the boot 1, he need only connect the extension belt 72 to the loop 14 of the tensile element 12 with the snap hook 71 and then has the additional comfort in operating the binding all day long.
Figure 14 shows an additional variant of the invention that can in principle be applied to all embodiment examples.
The shoe-side second binding part is no longer accommodated here in the heel area but instead, approximately in the middle of the boot 1. Correspondingly, the snowboard-side binding part 7 ie attached in a central position to the snowboard. Thus the boot is fastened only by the two pins and no longer by a front stirrup. In order to prevent swiveling of the boot about the rotational axis of the pins, tread plates 80, 81 are applied to the snowboard surface in the area of the heel and toe. These tread plates 80, 81 are preferably made of a resilient material in order to bring about a dampening and absorption of shocks and to allow a certain flexibility for a relative motion of the boot with respect to the snowboard. The tensile element 12 ie effectively connected to the pins as in the other embodiment examples, so that the binding otherwise operates in the manner described above. Since in this variant, the boot need not be pushed forward against a front stirrup, the lateral cheeks 7 of the snowboard-side binding part are configured somewhat differently. The upper side of the lateral cheeks has two guide surfaces 10,10' arranged in a V-shape and terminating in a circular dimple 17. By means of these guide surfaces 10,10', the boot is led in the direction towards the dimple 17 when the pins are placed on these guide surfaces, where then, according to the '' 2148~4~
embodiment example of Figuree 3 and 3a the dimple 22 insures that the pins are pressed inward and only go into their locking position upon reaching the opening 8.
In order to make the entire binding somewhat more elastic, an additional resilient block 82 ie inserted here between the surface of the snowboard S and the snowboard-side first binding part 7.
Description The invention pertains to a snowboard binding.
Such a binding was publicly exhibited at the ISPO
[tradefair] in Munich on February 24, 1994. This binding had a front :stirrup rigidly connected to the snowboard which reached over the front part of the boot sole and thus held i_t: in place. A pin running transversely to the boot's longitudinal axis was inserted through the' heel-side part of the boot sole and projected about 5-10 mm from the boot sole at both sides. A heel element to be screwed firmly in place on the snowboard consi:>ted of two lateral cheeks running parallel and projecting vertically from the snowboard surface; these had a vertically oriented slot, into which the part of tree pin projected out of the shoe could be introduced. A catch device on the lateral cheeks had the form of a hook which was pushed back during introduction of the pins into the slots and thus opened them, while with the pin parts completely housed in the slots it snapped into locking position and thus engaged the pins. 1:n order to open the binding, a lever on one of the lateral cheeks had to be operated, by which means the ~~t:irrups could be moved into the opening position anc~ the heel part of the shoe could be moved from the binding. This binding exhibited at the ISPO is also described in DE 4,311,630 A1, published subsequently.
AT 351,419 shows a ski binding with a shell nearly completely encompas~~ing the skier's boot that can be folded open and is fastened tightly to the surface of the ski. A shell part covering the front part of the foot and one covering the front side of the shin are articulated to pivot: at the front toe of the shell and can be pivoted between an opening or insertion position and a clo:~ed position. In the closed position the two aforementioned shell parts are locked in place by spring-loaded catch pine on the stationary shell parts. The spring-loaded bolts can be brought into an unlocked position by cables in order to allow a release in case of excessive stress or an opening for stepping out. In the latter case, the skier can operate the cables by a lever housed on the stationary shell part.
This ie thus a shell binding which ie intended to allow the use of very soft and therefore comfortable ski boots.
DE 2,556,817 A1 shows a ski binding with a binding plate that is attached by spring-loaded cables to the surface of the e,ki. Then a release force is exceeded, this plate can be removed a distance preset by the length of the cables from the surface of the ski. A recess is provided for this plate in the sole of the ski boot. A catch mechanism ie present in the interior of the plate and allows the locking of the plate in the recess of the ski boot sole.
In case of a release of the binding due to excessive force, therefore, the boot is released from the ski together with the plate. For opening, that is, stepping out, the boat must be detached from the plate. An unlocking mechanism that can be operated by the skier either manually or with a ski pole is provided on the plate for this purpose.
Another eo-called f'step-in" binding, in which skier need not operate any locking elements when stepping into the binding, is described in DE 4,106,401 A1. The boot is held by two ordinary stirrups, a front and a heel stirrup. The heel stirrup, however, is articulated to a tread element which is in turn attached eo as to be able to pivot to connection elements that are tightly connected to the snowboard. Herein is also attached a locking mechanism which grips the tread element when it is pressed completely down and holds it locked in position. In order to open the binding the skier must bend down and operate this locking mechanism by hand in order to open it. If there is snow or ice beneath the shoe sole, a locking of the tread element is not assured, since this snow or ice would make contact with the binding, before the tread element was pushed all the way down. Thus this binding is only functional to a limited extent.
DE 2,511,332 A1 shows a ski binding in which part of the binding ie likewise integrated into the heel of the ski boot. Two spring-loaded spherical-head bolts project laterally from the heel part of the boot sole and engage in matching recesses rigidly attached to the ski at the aides.
This a self-releasing safety binding which opens when a predetermined force i~ exceeded. This force is determined by the springs pushing the two bolts outward as well as by the shape of the spherical heads of these bolts and by the shape of the recesses for these spherical heads.
The regular opening of the binding is done at the front jaw holding the toe of the boot, while the heel attachment can only be overcome by tipping the foot to overcome the spring force. For emergencies in which the skier might be injured, it is also provided that the elements housing the bolts can be rotated eo that a groove located in them allows the boot to be pulled up and out of the binding.
DE 2,200, 056 A1 describes an additional release binding for skies. There too is provided a bolt pushed transversely through the boot sole; it engages with a hook-shaped, spring-loaded locking element. The entire locking element is pushed backward in the axial direction of the ski to open the binding; this is accomplished by operating a lever mounted on the ski.
DE 3, 141,425 A1 shows a safety binding for skis in which spring-loaded pine are attached to the boot and 21487~~
matching receptacle devices are attached to the ski. Here too, a mechanism fastened to the ski ie operated to open the binding.
Finally, DE 2,809,018 A1 shows a ski binding system consisting of ski boot and releasing binding elements, with a plate that projects beyond the boot incorporated into the sole or providing two bolts, somewhat separated, and pivoting hooks on the gki that grip laterally over this plate or the two bolts.
For snowboard bindings, many participants have long desired a so-called step-in binding, that is, a binding one could simply step into like a ski binding, without the snowboarder having to bend down to operate parts of the binding, such as locking etirrups_ on the other hand, safety bindings that would permit complete release of the shoe from the snowboard in case of excessive force applied are still problematic for enowboards, since the resulting safety problems for participants and bystanders have not yet been satisfactorily solved, despite numerous proposals.
Finally, the very serious problem of space also comes up in regard to snowboard bindings. The snowboarder is standing essentially transverse to the travel direction of the board, which means in practice that the angle between shoe longitudinal axis and gnowboard longitudinal axis is between 45~ and 90°, with some enowboarders even orienting their rear foot backwards, that is, at an angle of greater than 90° with respect to the direction of travel. Since snowboards, particularly the so-called alpine boards for snowboardere on prepared slopes, are becoming narrower and narrower, the toe of the boot and the heel of the ski boot are already projecting out over the contour of the snowboard. The principle can therefore be established that a snowboard binding must not project beyond the toe or heel of the boot, since this could lead to projecting binding parts touching the snow when the board is turned on edge. Fox- this reason, conventional ski bindings that have t:he step-in function are not suitable for snowbo~irds .
The initially mentioned step-in binding for snowboards, publicly announced at the ISPO fair in February 1994, avoids these disadvantages. Its comfort of use leaves something to be desired, however, since the snowboarder must: bend over to open the binding in order to operate a z~elease lever connected directly to the board's surface. The design of this release lever is also rather elaborate technically, and it tends to raise the weight. This runs contrary to the trend towards snowboards rind snow board bindings that are as light as possible.
The problem o:f t:he invention is therefore to improve the snowboaz~d binding of the type mentioned initially in such a way that the comfort of the binding is further improved and which nevertheless meets the requirements for light weight, functional security and costs as low as pos~~ible .
This problem i~~ solved by the snowboard binding according to the present invention.
The fundamental. and essential idea of the invention lies in moving essential parts of the binding and especially the 7_ocking device into the snowboard boots, which not on7_y enhances comfort when stepping out of the binding, :~o that the snowboarder need no longer bend when stepping out of the binding, but also achieves the advantages below. The binding parts to be fastened to the snowboard are light and insensitive to icing. The more expensive locking elements, also more subject to icing, axe located inside the boot or boot sole and are therefore better protected against icing ~14~'~4~
and can thus be combined with other enowboards that use the same binding parts_ An essential aspect of the invention lies in the fact that not only stepping into but also stepping out of the binding is considerably eased, so that a so-called "step-out" function is achieved. Finally it must also be especially emphasized that, after opening, the binding automatically returns to its initial position and is ready to be stepped into again without any active effort on the snowboarders part. This initial position is synonymous with the closed position, that is to says the locking elements have the same rest position in a completely open and a completely closed binding. Thus it ie impossible for the locking device to remain in a position, due to ice, perhaps, in which the binding might open inadvertently.
Additional advantages of the invention are explained in the description below.
The invention is described below on the basis of embodiment examples in conjunction with the drawings. These show:

Although the invention is described in most embodiment examples (except Figure 7) in connection with the use of a front stirrup, it should be pointed out that in all embodiment examples the invention can also operate without such a front stirrup.
In this case the shoe-side binding 7a a ' part, as.deecribed in greater detail in conjunction with Figure 14, is mounted roughly in the middle of the shoe and it is assured with base blocks that the tip of the Bole and.
the heel are positioned at the correct height with regard to the enowboard surface. In this case, it ie also possible to omit a binding base plate. However, if it is desired that the fastening of the snowboard-aide binding part to the snowboard should be more changeable, for instance, for adjusting the step size between the two bindings and/or the angle of rotation of the binding in regard to the longitudinal axis of the snowboard, then a base plate may be used in this variant as well.
Figure 1 shows a side view of a snowboard boot 1 just prior to its locked pasition with a binding element 2 to be fastened to the enowboard 5. This binding element 2 consists of a base plate 3 to be fastened to the snowboard, which can be done in a,variety of ways. As is common with so-called plate bindings, the binding element has a front stirrup 4 which grips over a sole projection 5 of the snowboard boot 1 and thus holds the front end of the snowboard boot in place. A second binding element 6, configured here as the heel part 6 of the snowboard boot 1, contains essential parts of the binding that cooperate with a heel element 7 mounted on the binding element 2.
In a rough sketch, this heel element 7 has two parallel lateral cheeks 7',7", the spacing of which is only slightly greater than the width of the heel part 6 of the snowboard boot 1. Each lateral cheek 7',7" has an opening 8 into which a spring-loaded pin 9 projecting laterally out of the heel part 5 can engage respectively.
For the secure fastening of the snowboard boot it ie necessary that it be pressed forward with a minimal force against the front stirrup 4. This therefore implies that ~14~~42 the spacing between the front stirrup 4 and the pin 9 or the opening 8 which'housee it'hae a certain maximum length in order to produce thie-force. When stepping into the binding the boot is normally pushed against the front stirrup 4 with a lowered front foot and a somewhat elevated heel, which does not produce sufficient pressing force, however. Then the pins 9 and openings 8 would not be sufficiently aligned when the heel goes down. In order to achieve this alignment , a downward incline 10 ie provided on each of the lateral cheeks 7',7"; these cooperate with laterally protruding projections 11 and press the boot ae a whole forward when the heel ie pressed down. The spacing between the pin 9 and the projection 11 corresponds exactly to the spacing between the opening 8 and the elope 1a, eo that ae the heel ie pressed down, the Spring-loaded pin 9 ie certainly guided past the opening 8 and then can engage in it. At the same time, the necessary force pushing the boot forward ie produced, which presses the boot toe firmly against the front stirrup 4.
When the pins 9 are engaged in the openings 8, the boot ie firmly attached to the enowboard and can no longer come loose inadvertently. To open the binding, the two pins 9 are pressed or drawn together inwardly in this embodiment example, so that they come loose from the openings 8, which means that the shoe can initially be raised somewhat by the heel and then removed from the binding. In order to displace the pine 9 in the manner described, a cable 12 ie provided, which ie led upward on the back side of the boot 1 to the shaft and held in place there by a belt 13. A grip loop 14 is placed on the cable 12. If the cable 12 ie pulled, then, ae will become clearer in the description below, the two pine 9 are pulled inward, which opens the binding.
214~74~
A peculiarity of the invention is therefore the fact that the opening or unlocking of the binding is done on the boot and not on the part of the binding that ie fastened to the snowboard or ski, ae in previously known snowboard or ski bindings. This has the advantage, among others, that the snowboarder need not bend down to the binding or use ski poles {not present in snowboarding anyway) for assistance, ae is the case with most ski bindings. If desired, the snowboarder can extend the length of the cables indefinitely, perhaps even up to belt height. An additional advantage is that essential components of the binding are integrated into the boot. Thus the binding element 2 which is constantly connected to the enowboard can be designed to be very simple and very economical, so that a snowboarder who owns several snowboards need only buy the more expensive binding parts once, together with the boot whereas only the more economical binding element 2 need be purchased for all snowboards.
It should also be emphasized that the heel part 6, which contains essential components of the binding, can also be manufactured as a separate part and subsequently screwed or glued on onto a boot or fastened in some other manner.
Figure 2 shows a side view of heel-side components of the binding in the locked state, that is, in which the pin 9 ie engaged with the opening 8. Also clearly a~een here ie the effect of the incline 10 and the projection 11, which cooperate to guide the boot while the heel is being pressed down such that the pin 9 and the opening 8 are oriented towards one another. It ie recognized better from Figure 2 that the lateral cheek 7 is guided so it can be displaced on a mounting block 15 attached to the base plate 3, which means that the binding as a whole can be matched to the shoe size. A setscrew 16 is provided for displacing the lateral ~~~~~~z cheeks.
The lateral cheeks have a dimple 17 at their upper end, which makes stepping into the binding easier, because with light pressure applied to the heel, the pin 9 moves to the lowest point of the dimple 17, which means that the projection 11 is then in the proper position with respect to the incline 10. It ie also clearly recognizable from Figure 2 that the lower aide of the shoe sole of the heel part is not yet in contact with any binding elements such ae the mounting block 15, but instead maintains a distance from it.
Thus a secure locking of the binding occurs even if there is snow underneath the boot sole. Since the heel ie supposed to be somewhat higher than the toe of the boot for snowbaards anyway, with the invention one can dispense with the wedge underlay otherwise used for the heel part.
Clearly recognizable in Figure 3 is the position of the two lateral cheeks 7',7", which stick out vertically from the snowboard parallel to one another and house the heel part of the snowbaard boot between them. Both lateral cheeks 7',7" are connected together by a connection element 18 that,liee on the mounting block 15. Both lateral cheeks 7',7" are extended in the direction of the base plate 3 beyond the connection element 18 and grip over the mounting block. l5 with inward-directed arms 19',19". Thus the heel element 7 ie firmly on the mounting block 15 and can be displaced only in the longitudinal direction of the snowboard. For this purpose, the mounting block 15 has an opening 20 for housing the setgcrew 16 as well ae a slot, not illustrated, which opens the opening 20 to the upper side of the mounting block 15, eo that a threaded part gnat shown) connected to the connection element 18 is in connection with the setecrew 16, with which a longitudinal adjustment of the heel element 7 is possible.
'' 2148'~4~
It is also easily recognizable from Figure 3 that the lateral cheeks 7',7" have an incline 21',21"; respectively, above the openings 8 which insures that the spring-loaded pin ie pressed inward into the heel part 6 of the shoe.
In order to design the effect of the dimple 17 to be more efficient, it is practical to insure that the bolts 9 are only pressed inward in the position in which they make contact with their cylindrical part on the upper side of the lateral cheeks. For this purpose an additional dimple 22 running parallel to the longitudinal extension of the inclines 7',7" ie provided in the vicinity of the inclines ' 21',21"; the dimple ie best recognized from Figure 3a and has a greater angle of inclination with respect to a central axis 23 perpendicular to the snowboard than the incline 21'.
Only when the bolt 9 ie in the deepest point of the dimple 17 does its free end make contact with the wall of the dimple 22, so that it is pressed inward when the heel is pressed downward.
It is also recognizable from Figure 3 that the central axis 24 of the openings 8 is spaced away from the upper side of the connection element 18, with this spacing being greater than the corresponding spacing between the midpoint of the pin 8 and the bottom aide of the sale of the heel part 6 of the snowboard boot 1. In that way the functioning of the binding ie not impaired by snow or ice on the sole of the snowboard boot_ Figure 4 shows a plan view of the inside of the heel part 5 of the snowboard boot 1. This heel part has a cavity 25 in which the pine 9,9' and the mechanism for displacing them are accommodated. Along an axis 26 that coincides with the axis 24 of Figure 3, the heel part 6 has two opposing aligned openings in which the guide bushings 27,27' are inset and in which the pins 9,9' respectively are guided so -- ~14$7~~
se to be displaceable. Both pins are pressed outward by a spring 28, until here in the embodiment example of Figure 4 the pins 9'9', directly connected at their inside end faces by the spring 28, abut against a atop formed here by the guide bushings 27.
The spring 28 ie constituted here se a U-shaped stirrup. The length of the pins 9,9' is dimensioned such that the pins 9,9' only protrude laterally by a predetermined amount' for instance 5-1d mm, from the contour of the heel part 6_ The ends of the pine 9,9' protruding outward are rounded off in order to ease the insertion of the pine between the two lateral cheeks 7',7". The radius of curvature of this rounding ie equal to half the diameter of the otherwise cylindrical pins, so that the points of the pine protruding outward form a hemisphere.
A tensile element 29,29', which may be a plastic or metal cable in the simplest example, ie formed on the pins 9,9', respectively, in order to open the binding. These two tensile organs are guided in opposite directions over a deflection stanchion 30 and connected together in a connection element 31, se well se to the cord 12 WhlCh is guided through an opening 30 from the inside of the heel part 6, as illustrated in detail in Figure 1. The cable 12 can also be made of plastic or metal. If one pulls on this cable 12, the tensile force will be directed onto both tensile elements 29,29' and transferred by way of the deflection stanchion 30 to the pins 9'9' eo that the latter are drawn inward along the axis 26 into the heel part 6. If the cable 12 ie once again released, the two pin are pushed outward again by the spring 28_ It can also be easily recognized from Figure 4 that the projections 11,11' stick out roughly just se far se the pine 9,9' from the contour of the heel part 6, which shield the z~~~~~~
pine 9,9' so that the danger of being caught on the pine in ordinary walking is reduced. To this end, the projections 11,11' also have a rounded off shape, an elliptical shape far instance, and thus act as guards to prevent the pins 9,9' from catching on any objects_ The surfaces 33,33' of the projections 9,9' immediately facing the pins 9,9' are shaped essentially smooth and are fitted to the incline 10 (Figure 1).
Finally, it ie also recognizable in Figure 4 that the heel part 5 ie closed off all around and thus can be employed as an aftermarket product for conventional snowboard boots. Naturally it is also possible to integrate the heel part 6 completely into the shell of the snowboard hoot.
The side view in Figure 5 clarifies the position of the spring 28, the tensile element 29 and the cable 12 in the heel part 6 of the snowboard boot 1. The deflection stanchion 30 can be provided as a separate part, but it can also be molded in one piece with the heel part, which generally consists of plastic.
Figure 6 shows another variant of the heel part, differing from the embodiment example of Figures 4 and 5 by the spring and the tensile elements. The spring 28 is constructed here as a coil spring oriented along the axis 26 and pressing against the two pins 9,9'. The two pins 9,9' each have an enlargement 33, 33' respectively at their ends, on which the spring 28 is supported and each of which also supports one arm of a lever 34,34' on the side of the enlargement 33 opposite the spring 28. This can be done on one side _of the pin . The corresponding lever arms can also be constructed as claws that grip the pin on both sides. These arms are bent in a convex shape in order to slide along the enlargement 33 during pivoting of the levers 2148'42 about pivot axis 35,35' respectively. The two other arms of the lever 34,34' are roughly perpendicular to the aforementioned arms and are connected via two short cables 36,36' to cable 12. In the illustration of Figure 5, the cable 12 is being pulled, eo that the two pins 9,9' are roughly in the unlocked position. In the locked position, the two pine 9,9' abut against guide bushings 27,27', which in turn define the limit position of the pins 9,9'.
The variant in Figure 7 likewise works with a coil spring 28 and levers 34,34'. It is distinguished from the embodiment example of Figure 6 in essence only by the shape of the levers and their attachment to the pins 9,9'. The levers 34,34' are connected to the pin here by a slot connection, that ie, the levers 34, 34' each have a slot 37,37', into which a bolt 37' running perpendicular to the axis 26 of pins 9' is inserted. When the levers are pivoted, this bolt 37' slides along the slot 37. Otherwise, the functioning corresponds to the embodiment example of Figure s.
The embodiment example of Figure 8 likewise operates with a coil spring 28 and a rod linkage, which ae a result the desired tensile force is exerted on the pins 9,9'. The pine 9,9' are bent so that the bent arms 38,38' are offset with respect to the axis 26. The free ends of these bent arms 38,38' are connected by slot connections 39,39' to a pivoting lever 40, the pivot axis of which is positioned mirror-symmetrically to the two pins 9,9' on the axis 25.
The cable 12 can either be articulated at one end of the pivoting lever 40 or, depending on the desired exit point for the cable 12, to an additional pivoting lever 42, which ie firmly connected to the pivoting lever 40 and thus transfers the tensile force of the cable 12 to the latter.
In the embodiment example of Figure 9, sections of the 2~.~8'~4~
pine located in the interior of the second binding part 6 are mutually laterally offset and here are pressed outward by a spring (not shown . The mutually overlapping part 42 of the pins has passage openings 43 with inclined sides 44.
Inserted into these passage openings ie a bolt 45 which hoe oppositely oriented ramp inclines 46,47. If the bolt 45 connected to cable 22 ie displaced, then the two pins 9,9' are drawn inward, which opens the binding. The spring with a force tending to press the two pine 9,9' outward can be embodied in a great variety of ways. It may, for instance, attack directly at the bolt 45 as an extension of the central axis and be constructed ae a compression or tension spring. It may also be designed as a strap spring, corresponding to the embodiment example of Figure 4.
Finally, it ie also possible to provide one or two compression springs that act directly on the pine.
In the embodiment example of Figures 10 and 11, one or two pins are attached to the lateral cheeks 7',7", while the locking mechanism has the form of one or two pivoting levers which grip behind the pin or pins_ Figure lOA shows a side view of the heel part 6 of a snowboard boot 1. In the rear sole areas a recess 48 extending inward on both sides, has an inclination 49 in the area pointing towards the sole tip, which ends in a rounding 51 near the lower side 50 of the sole. A locking lever 52,52' ie housed in each of these two cutouts 48, both locking levers 52,52' being fastened to a Gammon rotating shaft 53_ This rotating shaft runs crosswise through the enowboard boot through the cavity 25. Another lever 54, connected to the cable 12, ie attached without rotational play to the rotating shaft 53. Furthermore, a spring, not shown, can be attached to this lever 54 to press the lever 54 and thus the two lacking levers 52,52' opposite the 214~'~4~
tension direction of the cable 12 in the direction of the shoe toe, thus pressing the two locking levers into their locked position. The locking levers 52 are bent in a bow shape and have a flat locking surface 55, which is oriented roughly horizontally in the locked position and firmly contacts the associated pins 9,9' placed on the lateral cheeks 7',7 " . Adjacent to this locking surface 55, the locking lever 52 has an inclined plane 56, which insures during the stepping-in process that the locking levers 52,52' are pivoted backwards into the opening position se soon se the inclined plane 56 touches the pins 9. As soon se the tip of the locking levers elides past the pin 9, the locking levers 52 are pressed forward by spring force into the locking position, and the binding is closed.
4sThen stepping into the binding, the incline 49 serves as a guide surface which, as soon as it makes contact with the pin 9, displaces the boot forwards_ It thus has essentially the same function as the projection 11 with the guide surfaces 33 in the previously described embodiment examples.
The locking levers are well protected in the recesses 48, so that there is no danger that these levers will get caught somewhere during the stepping-in process.
It can be seen even better from Figure lOB how the two pine 9,9' are fastened to the lateral cheeks 7',7" and point inwards at one another. The recess 48 and its protective function for the locking levers 52,52' are also clearly recognizable.
In connection with Figure 10A, it should also be painted out that even in the inside of the boot, the cable 12 can be directed upwards into the boot, running, for instance, between shoe liner and shell. This arrangement is a fundamental possibility with all embodiment examples.
214~'~42 In order for the locking position of the locking levers to be securely fixed in place and not dependent on the force of the spring, it ie practical to arrange the central axis of the of the rotating shaft 53 above the central axis of the pins 9 with the binding closed or even to displace it somewhat towards the boot toe. Forces directed perpendicularly upwards from the enowboard surface would then in the first instance not exert any torque onto the locking levers 52 or, in the case of an axis of the rotating Shaft 53 displaced even further forward, would even produce a torque forcing the locking levers 52 more firmly into the locking position.
In the embodiment example of Figure 11, a pin 9, passing all the way through and connecting the two lateral cheeks 7',7" and only one central locking lever 52, which has the same cross section in the side view of Figure 11A as the two locking levers 52,52' of Figure 10, are used. The boot Bole has a recess 57 opening downwards and ending laterally Figure 11A) in an opening which in turn has an incline 58 on its wall pointing towards the boot toe and, in cooperation with the pin 9, forcing the boot forwards towards the toe. Here too the central locking lever is pressed by a spring, not shown, into the locking position.
Otherwise the function is the same ae in the embodiment example of Figure 10.
In the embodiment example of Figure 12, the pins 9 located in the interior of the second binding part 6 are connected by articulated levers 60,60' to the pivoting lever 40, with the ends of the articulated lever 60,60' each being connected by a pivot joint to the pins 9,9' and the pivoting lever 40. The central axis of the pivoting lever 40 rune perpendicular to the central axis of the pins 9,9'. One central axis of the ~ articulated lever ~. 214~74~
60,60', by contrast, is positioned at an angle of roughly 45° to the central axis of the pivoting lever 40. The two pivoting levers 60,60' are parallel to one another and are each connected to one end of the pivoting lever 40. If the pivoting lever 40 is rotated about its pivot axis 41 (clockwise in Figure 12}, then the articulated levers 60,60' each apply a tensile force to the pins 9,9' and pull them into the interior of the second binding part 6. The tensile element 12 is connected to one end of the pivoting lever 40.
For this purpose, a blind hole 63 and a continuing [smaller]
through-hale 64 are provided on the pivoting lever. The tensile element 12 is threaded through the through-hole 64 and thickened at its end by a knot, a press-on sleeve or the like so that it can no longer be pulled back through the through-hole 64. The thickened end is then arranged to be sunk into the blind hole 63.
In contrast to the previously described embodiment examples, the tensile element 12 runs in the interior of the second binding part 6 roughly at a right angle to the central longitudinal axis of the shoe and ie therefore directed outwards laterally on the boot.
The second binding part 6 is constructed as an injection-molded plastic part, as was possible in principle for the other embodiment examples as well, and can be subsequently screwed onto the sole of a boot. Screw holes 65 are provided for this purpose. In order to be able to accommodate binding parts in this binding element 6, a recess 66 ie provided and houses the individual parts, including the spring 28. This spring is constructed here as a leaf spring bent in a U-shape, supported on the ends of the pins 9,9' projecting into the interior of the binding part, as becomes clearer from the detailed view in Figure 12a.
.....
21~874~
It can also be recognized in Figure 12 that the second binding part 6 has drill holes 70 on both sides through which the tensile element 12 can be led out, since it is fundamentally desirable to lead the tensile element to the outside of the respective boot, that ie on the right side of the right boot and on the left aide of the left boot.
Figure 12a shows an enlarged detail view of a specific aspect of Figure 12, namely, the guiding of the pin 9 through the wall of the second binding part 6. Since a high degree of flexibility regarding the motions of the foot in all directions ie desirable in enowboarding, but moat snowboard boots,in use with plate bindings have a relatively hard outer shell, this flexibility cannot be achieved by the shoe alone. For this reason, the pin 9 is flexibly supported in relation to the second binding part 6, which is rigidly connected to the boot. To this end, the pin 9 is supported so as to be displaceable in a metal easing 69, which is in turn connected to the second binding part 6 by an elastic easing 68. This elastic easing 68 can consist, for instance, of rubber or some other resilient material, such as an elastic plastic. In manufacturing the second binding part 6, the plastic "shell" of which is produced by injection molding technology, it is possible to mold on this flexible easing 68 in a second work step in the same injection molding form, which means that the easing 68 also obtains a very good connection to the binding part 6. Nat only are shocks dampened and absorbed by this resilient supporting of the pine, which absorb the essential forces between the gnowboard and the boot, the boat can also be tilted in an angle of 1-3° perpendicular to the longitudinal direction, which considerably increases comfort in use.
It can also be recognized from Figure 12a how the spring 28 is supported on the pin 9. In the embodiment ~. 21~87~~
example shown here, the latter has a radially projecting collar 67, which, on one hand, serves as a atop that defines the limit position of the bolt and, on the other, supports the spring 28. Here the spring has a drillhole 28' through which projects the interior end of the pin, to which in turn the articulated lever 60 (Figure 12) ie connected by way of the pivot bearing 61. It should be emphasized at this point that the flexible bearing of the pine according to Figure 12a can be applied td the variants of the invention.
Alternative to or in combination with this flexible bearing of the pin, the first binding part 7 can also be flexibly attached to the snowboard, for example by inserting a resilient plate of rubber or flexible plastic between the snowboard surface and the first binding part (as will be explained more closely in connection with Figure 14).
Figure 13 shows a refinement of the invention in which the tensile element 12 for opening the binding ie extended further and is partially integrated into the snowboarder's clothing. The tensile element can thus be led upward to an arbitrary height to suit the comfort of the snowboarder. It has proven practical to guide the tensile organ roughly up to the height of the thigh, where it can be gripped by the Bnowboarder's hand without any bending at all. For this purpose, a loop 13 on upper end of the tensile element 12 ie connected by a snap hook 71 or some other easily operated suspension device to an extension belt 72, preferably guided in the interior of the enowboard pants and only emerging at an opening 76. There the extension belt 72 has another loop 77 that can be gripped by hand. This loop 77 is held in position by an rubber belt 78 fastened, for instance, to the belt of the pants or a loop sewed onto the pants_ Most contemporary enowboard pants have a sleeve 74 that is sewn onto the pants along a seam 75 at the level of the , ~ ~148'~4~
shin and extends partially over the upper part of the boot 1. The extension belt 72 is guided in this area between the pants 73 and the sleeve 74. When the enowboarder puts on the boot 1, he need only connect the extension belt 72 to the loop 14 of the tensile element 12 with the snap hook 71 and then has the additional comfort in operating the binding all day long.
Figure 14 shows an additional variant of the invention that can in principle be applied to all embodiment examples.
The shoe-side second binding part is no longer accommodated here in the heel area but instead, approximately in the middle of the boot 1. Correspondingly, the snowboard-side binding part 7 ie attached in a central position to the snowboard. Thus the boot is fastened only by the two pins and no longer by a front stirrup. In order to prevent swiveling of the boot about the rotational axis of the pins, tread plates 80, 81 are applied to the snowboard surface in the area of the heel and toe. These tread plates 80, 81 are preferably made of a resilient material in order to bring about a dampening and absorption of shocks and to allow a certain flexibility for a relative motion of the boot with respect to the snowboard. The tensile element 12 ie effectively connected to the pins as in the other embodiment examples, so that the binding otherwise operates in the manner described above. Since in this variant, the boot need not be pushed forward against a front stirrup, the lateral cheeks 7 of the snowboard-side binding part are configured somewhat differently. The upper side of the lateral cheeks has two guide surfaces 10,10' arranged in a V-shape and terminating in a circular dimple 17. By means of these guide surfaces 10,10', the boot is led in the direction towards the dimple 17 when the pins are placed on these guide surfaces, where then, according to the '' 2148~4~
embodiment example of Figuree 3 and 3a the dimple 22 insures that the pins are pressed inward and only go into their locking position upon reaching the opening 8.
In order to make the entire binding somewhat more elastic, an additional resilient block 82 ie inserted here between the surface of the snowboard S and the snowboard-side first binding part 7.
