Description

The invention relates to a snowboard binding according to the Oberbe handle of claim 1 and a snowboard boot for use with such a.

While modern ski bindings for alpine skis practically consistently a comparable basic structure and similar functionality have and all alpine ski boots are adapted, are for Snowboards known and very different bindings on the Market.

Due to the fact that a snowboarder often more than an alpine skier at least one foot out of the binding must solve - namely on every lift ride - there is an essential Usage value of snowboard bindings in the poss possibility of easy and comfortable getting on and off. It have therefore been dominant lately belt or buckle bindings also for soft snow board boots (soft boots) so-called step-in bindings sets, where an entry without a manual operation and an exit after operating a pull loop or a Fe derspange or the like is possible. There are several Systems for locking the snowboard boot in the bin dung.

Several known systems include a binding plate with silk tenwangen, on which locking elements for Ver locking with the snowboard boot in the sole area  are seen. There are also additional clips for fixation of the front end of the boot on the binding.

A snowboard binding is known from EP 0 680 775 A2 from a sole part integrated in the snowboard boot and one interacting with it, constantly connected to the snowboard first binding element. In the sole part there are two of them Side surfaces spring-loaded, laterally protruding Zap fen provided in a corresponding opening of the he most binding element can snap into place. By means of a train loop and transmission device in the boot can the Zap fen are withdrawn, thereby opening the binding. In addition, one is in the front area of the binding Retaining clip across the sole end of the snowboard boot seen.

Another step-in / step-out snow is known from WO 97/41931 known board binding, the one to be attached to the snowboard Has binding element with two side cheeks. In every be tenwange is a protruding bolt approximately parallel to Snowboard surface slidable against an energy storage device is stored in a corresponding opening in the snowboard boots or a corresponding protrusion on the boot spreads. This binding also works after the step-in Principle by using the bolts when putting on the snowboard boot pressed back into the side cheeks and after complete by placing the boot in the openings provided snap into the boot. The binding element holds the snowboard boots in the middle, and the front or back The area preferably rests on a tread element on the Snowboard surface. There is a tension element on the binding attached, with which the bolts for getting out of the binding can be withdrawn manually.

AT 405 611 B is a binding and a shoe for snow boards known, the binding one on a base plate arranged binding plate and lateral holding parts.  

These are formed by side walls in which the free ends of a spring clip to be pressed down by hand. Im with ten area of the shoe are lateral holes for engagement these ends of the spring clip are provided.

The known bindings or binding shoe systems from soft Step-in type are sufficient for fixing the boot regarding the snowboard and the power transmission that can be achieved with it The demands of ambitious snowboarders are limited.

The invention is therefore based on the object of improving to specify the snowboard binding system of the generic type, which in particular ensures optimal power transmission from the driver guaranteed on the snowboard and is easy to use.

This task is solved with regard to its system aspect by a snowboard binding with the features of claim 1, and the solution still affects a snowboard boot with the features of claim 14.

The invention includes the basic idea in one Step-in system a front, located in the forefoot area central locking device with one in the middle or rear area arranged rear, side locks to combine. This solution offers maximum Forefoot comfort and high lateral flexibility smallest possible longitudinal play and therefore enables optima le power transmission from the snowboarder's foot to the board.

In a preferred embodiment, it also closes the - relatively independent - thoughts of training the front Locking device as a snap-lock latch / twist-lock System. Here is in particular a down from the system part on the shoe side, the sole holding plate, U- or L- shaped retaining bracket provided to the binding egg tig an elongated recess corresponds to which one Snap or twist lock is assigned.  

When the snowboard boot is inserted into the binding, the Shoe toe - guided through the shoe on the side ten cheeks of the binding base body or (preferably) on one Side by one to adapt to the shoe size of the snow board driver's adjustable stop - with the bracket above positioned the recess. When the bracket enters the recess becomes the spring-loaded snap or rotating latch pushed to the side or twisted. The snap latch jumps after passing the bracket back to its original position back, reaching behind the bracket and thus in verti calender direction fixed. The rotary latch is inserted through the bracket turned its end position and there z. B. by a pawl blocks and fixes the bracket also in vertical Direction.

Because of the correspondence between the bracket and recess there is also a lateral fixation, the bracket-transom cons but construction allows a slight pivoting of the Boot toe compared to the binding, which is more advantageous Way he "rolls" the foot to control the snowboard is possible. The construction also allows relative movement between the boots and the board in the longitudinal direction, especially re with elastic bends (flex) of the board, which also contributes to advantageous driving characteristics. In addition, here due to a flexible, relatively soft design of the sole Holding plate and the sole of the boot overall, what na of course to a high level of comfort of the snowboard boot wearing. The flexibility of the sole holding plate in turn leads to form a not completely rigid connection between the front and rear locking device and mini miert the influence of the binding and the boot on the mechani properties, especially the elasticity and that Vibration behavior, of the snowboard and thus contributes to one high driving comfort.  

In another preferred - also relatively independent - Expression of the inventive concept also includes the rear Locking device a snap lock mechanism, and in particular with a first one arranged in the binding and a second one, in a snowboard boot (in the sole hold plate) arranged snap latch. Both are essentially move transversely to the longitudinal axis of the bond under spring preload Lich and coaxially in the preferred embodiment arranges.

By one here with the snap lock on the binding base body first compression spring with a first, larger spring constant and the latch on the sole plate a second pressure spring with a second, smaller spring constant and with first compression spring assigned opposite bias direction is a particularly advantageous combination of effects to reach. There is only a single movement on the binding Lich locking element provided, and this can be in one manual actuation in a simpler and less complex manner can be assigned to the unlocking element. The second, locking element located in the sole holding plate to a certain extent by the aforementioned locking element on the Binding controlled and does not require a separate actuating element ment.

The snap bolts mentioned are in particular pin or pin-shaped, what the construction in terms of associated as guide sleeves or bores Recordings and the - as simple and inexpensive screws springs realized - compression springs simplified.

The aforementioned actuator for unlocking the movable Locking element on the binding has one advantage stick execution an easy to use and reliable Lever mechanism on. It is preferred with the front Locking device connected, so that this at the same time  the rear one can be unlocked with one hand. The Connection is preferably made via a pull rope.

Advantages and advantages of the invention result in practice from the subclaims and the following description Exercise of a preferred embodiment with reference to the figures. Of these show:

Fig. 5 is a sketch-like representation (excerpt position of the binding in side view) of an actuating device for actuating a snowboard binding according to an embodiment of the invention for getting out of it.

Figs. 1A to 1C are external views of a snowboard binding 1 from above (Fig. 1A), from the back (Fig. 1B) or the right (Fig. 1C). The snowboard binding 1 comprises a binding base body 3 with two side cheeks 5 and 7 , which is rotatable about a central vertical axis of rotation 9 , and an adjustable heel strap 11 made of metal. In the front region of the binding base body 3 in FIG. 1A, a recognizable by the side wall 7 has two adjusting screws 12 a for adjusting the binding to the boot size of the snowboarder adjustable lateral stop 12 and a längli che, slot-shaped recess 13, and in Fig. 1A and 1B are in the side walls 5, 7, guide sleeves 15, 17 can be seen as the end of a snap-bolt 19, which (as described in more detail below) to the rear Verriegelungsein direction of the binding part. Further, in Figs. 1A to 1C in sections a pivoting lever 21 with a finger piece 21 a can be seen, which is also part of the direction to the rear Verriegelungsein and further described in greater detail below.

In FIGS. 2A to 2C, the mechanical structure of the Snowboardbin is dung 1 shown in greater detail, in synoptic depicting lungs based on a plan view (Fig. 2A), rear view (Fig. 2B) and a side view from the right (Fig. 2C) and with sections shown as a sectional view and with the inclusion of parts of an associated sole holding plate 23 of a soft boot 25 in the illustrations.

In FIG. 2A, in a partial sectional view integrated into the plan view (cross section along a horizontal sectional plane) and a longitudinal sectional view arranged next to this, a front locking device 27 arranged in the region of the recess 13 is first shown. As a boot-side component, this comprises a U-shaped holding bracket 29 which is firmly inserted into the sole holding plate 23 at the front end and projects downward therefrom. On the binding side, the front locking device 27 comprises a flat snap latch 31 which is transversely to the longitudinal extent of the retaining bracket 29 and which is biased into the recess 13 via a helical spring 33 acting as a compression spring and to which a pull cable 35 is fastened. In the longitudinal section it can be seen that the binding-side components of the front locking device 27 are accommodated in an approximately rectangular base body 37 , in which the recess 13 is incorporated with flanking inlet slopes.

In particular, in Fig. 2A and 2B remains the construction of a rear locking device 39 can be seen. This includes, in addition to the above-mentioned, by an internal Schraubfe 40 in the direction of the opposite side cheek 7 in front of tensioned snap bolts 19 in the side cheek 5 as a further main component, a second snap bolt 41 embedded in the sole holding plate 23 , the middle part of which is a compression spring acting coil spring 43 is surrounded. The second snap bolt 41 has at its left side cheek 7 neigh end an attached end piece 41 a and in the middle loading area an abutment surface 41 b, on which the compression spring 43 is supported at one end. With its other end, the compression spring is supported on a first holding plate abutment 45 a, and a second holding plate abutment 45 b serves as a stop for a movement of the snap bolt 41 in the direction of the right side cheek 5 caused by the compression spring. At its end adjacent to the snap pin 19 , the snap pin 41 has a widened head 41 c, which, in interaction with the second holding plate abutment 45 b, limits its deflection in the direction of the left side cheek 7 .

In the figures it can be seen that the first and second snap bolts 19 , 41 are arranged coaxially to one another and perpendicular to the (dash-dotted line) longitudinal axis of the binding 1 . The snap pin 19 is guided in the guide sleeve 15 on the right side cheek 5 , and the guide sleeve 17 on the left side cheek 7 serves to receive and guide the end piece 41 a of the second snap pin 41 . The stiefelseiti ge snap bolt 41 is arranged together with the associated compression spring 43 in a continuous channel 46 in the sole holding plate 23 , the adjacent portion of the snap bolt 19 also serves as a guide for this adjacent portion.

The above-mentioned pivot lever 21 is pivotally mounted about the longitudinal axis of the snap bolt 19 and is connected at its end 21 b opposite the finger piece 21 a with respect to the axis of rotation to a coil spring 47 acting as a tension spring, the other end of which is fastened in the binding base body 3 . In a gear sleeve 49 arranged in the area of the axis of rotation, a pivot lever transmission 51 (not shown in detail) is arranged, which converts a pivoting movement of the pivot lever 21 into a retraction of the snap bolt 19 connected to the pivot lever transmission 51 . With the binding base body 3 facing end of the pivot lever 21 , one end of the traction cable 35 is connected, at the other end of which the snap latch 31 is attached.

. A synoptic Dar turn in type position involving binding-side elements of the system - - In Figures 3A to 3C is a boot sole 53 of the soft boot 25 in the manner of a top view (FIG. 3A), a cross-sectional view taken along a ver tical, the longitudinal axis the snap bolts 19 and 41 contain the sectional plane ( FIG. 3B) or as a side view with a partial sectional view in the area of the holding bracket 29 ( FIG. 3C). The boot sole 53 is made of soft elastic material (rubber or foam plastic) and is positioned opposite the sole holding plate 23 over the molded cylindrical extensions 55 and firmly connected to the sole holding plate. As can best be seen in Fig. 3C, the sole holding plate 23 carries in the area of the rear locking device 39 approximately U-shaped side parts 57 , 59 , which open downwards with (not specifically designated) inlet slopes and into which Binding inserted state of the soft boot 25 surround the binding-side guide sleeves 15 , 17 .

The functioning of the binding shoe system shown in FIGS. 1A to 3C and described above in its construction is as follows:

The soft boot 25 is inserted with a rough alignment in the longitudinal direction by the heel retaining band 11 and in the lateral direction by the side cheeks 5 , 7 and the stop 12 in the binding 1 , ie placed on the binding base body 3 . On the one hand, the holding bracket 29 (guided through the inlet bevels on the recess 13 ) engages in the recess 13 and there presses the snap bolt 31 , which is designed in a wedge shape on its top, to the side. As soon as the soft boot 25 approaches the surface of the binding base body 3 , the retaining bracket 29 has penetrated so far into the recess 13 that it has passed the snap latch 31 and this can spring back into the initial position and now the retaining bracket 29 and thus the Locked toe of the soft boot.

When the boot is put on, the side parts 57 , 59 also lead with their run-in bevels, the rear section thereof, especially the incorporated channel 46 , into a position aligned with the snap pin 19 . During the placement, the spring-loaded snap pin 19 is pressed against the spring force into the side cheek 5, and the sole holding plate 23 and thus the sole 53 of the boot can slide past it. After it has been placed in alignment with the front and rear locking devices on the binding, the snap pin 19 is again pushed out of the side cheek 5 and into the channel 46 in the sole holding plate 23 , whereby this is already locked on one side with the binding 1 . It should also be noted that the sole of the boot in the heel area does not rest on the surface of the binding base body, but the sole holding plate 23 (to avoid malfunctions due to snow accumulating there) on the guide sleeves 15 , 17th rests.

Since the spring force of the arranged in the snap bolt 19 Druckfe is greater than that of the - counter-acting - compression spring 43 in the sole holding plate 23 , the sole-side snap bolt 41 is also up to the stop on the plate abutment 45 b in the direction of the opposite Side cheek 7 pressed so that the end piece 41 a engages there in the guide sleeve 17 and the holding plate also locks on this side with the binding. Overall, a three-point locking of the boot with the binding via two lateral locking points in its rear area and a central locking point in its front area is thus created.

To get out of the binding, the pivot lever 21 is taken at the fin gerstück 21 a and pivoted upward against the force of the tension spring 47 upward, whereby the pivot lever translation 51 of the snap pin 19 is drawn into the side wall 5 . Here, the compression spring 43 arranged in the sole holding plate 23 can relax and presses the snap bolt 41 arranged there up to the stop on the second holding plate abutment 45 b back in the direction of the (right) binding side cheek 5 . The end piece 51 a slides out of the guide sleeve 17 , and as a result, both side Verrie are successfully solved with the binding 1 in the rear of the soft boot 25 .

Since, in addition, with the pivoting of the pivot lever 21, the end of the pull cable 35 which is fastened there is pulled backward, the snap bolt 31 is also moved out of its engagement position with the retaining bracket 29 and thus the retaining bracket 29 is released. The boot is thus unlocked from the binding as a whole, and the snowboarder can step out of the binding.

Fig. 4 shows in a schematic diagram in the manner of a sectional view position along a vertical and perpendicular to the longitudinal axis of the plane of the cutting plane a front locking device 27 'in another embodiment.

Here is a relatively high and narrow base body 37 'with egg ner central recess 13 ' with (not specifically designated) inlet slopes is provided, which can engage in a corresponding recess from the associated (not shown) sole holding plate. In this arrangement, it is avoided that the bracket 29 protrudes from the sole holding plate after un th. In the figure, the state of the front locking device 27 'is shown in the rest position and in its position with the retaining bracket 29 inserted at the same time.

The centerpiece of the locking device 27 'is a rotary latch 61 which is rotatable about an axis of rotation 63 and biased by a torsion spring element 65 in the open position. The rotary gel 61 has a to the diameter of the bracket 29 is fitted engagement opening 67 and a toothed portion 69 on the opposite side with respect to the axis of rotation 63 . In this area, the rotary latch 61 is assigned a pawl 71 which is displaceable transversely to the axis of rotation 63 and which (in a similar manner as in the snap latch 31 in the first embodiment described above) has a compression spring (not shown here) for prestressing in the direction of the Recess 13 'and a pull rope for triggering is assigned.

When entering the binding, the rotary latch 61 has the swivel position designated by A, the engagement opening 67 being aligned with the recess 13 'and the retaining bracket 29 being able to penetrate freely from above. When engaging, he presses on the bottom wall area of the engagement opening 67 and turns the rotary latch 61 (counterclockwise in the figure) into the pivot position B. During this rotary movement, the pawl 71 is counter to the pressure force of the associated compression spring by the teeth of the toothed portion 69 of the recess 13 'pressed away (to the right in the figure). When the bracket 29 has arrived in its end position, the pawl 71 , driven by the compression spring, slides back to the recess until it bumps against the adjacent tooth of the toothing section, thereby locking the rotary latch 61 in the position designated by B. This lock cannot be released by lifting the tip of the boot. It is released by pulling on the pull rope (not shown here), through which the pawl 71 is moved to the right until the toothed section disengages from it and the torsion spring element 65 returns the rotary latch 61 (clockwise in the figure) to its open position A. turns.

In Fig. 5 is an alternative to the embodiment described above implementation of means for releasing a binding of the type described above be outlined. A modified binding 1 'has a modified pivot lever 21 ', which is guided in a (as detail D in a synoptic representation in plan view th) guide piece 20 'on a side wall 5 '. This is rotatably about a near the surface of the binding basic body 3 'located axis of rotation 21 / A' against the action of a torsion spring element 22 '. It is approximately C-shaped in the side view and the ends of two pull cables 35 A 'and 35 B' are fastened to it in its central region. The pull rope 35 A 'is attached with its other end (analogous to the pull rope 35 in the embodiment described above) to the snap lock of the front locking device and pulls it back when the pivot lever 21 ' is confirmed. The second pull rope 35 B 'is attached with its other end to a modified snap pin 19 ' and pulls it back when the pivot lever is actuated. Both the front and the rear locking device are thus unlocked via the pivot lever 21 '. Note the guidance of the pull cables 35 A ', 35 B' in predetermined rigid guides (not shown in the figure).

The implementation of the invention is not described above NEN examples, but also in a variety of Modifications possible that lie within the scope of professional action gene.

So is the front locking device in many others Realizable variants that are fixed in vertical and lateral direction while ensuring play in the longitudinal direction direction and the possibility of limited swiveling  result in a longitudinal axis in the forefoot area. It can the locking element on the binding side is also rotatory move a vertical axis, and it is possible to hold the bracket gel on the binding side as a movable locking element to lead.

The rear locking device does not necessarily have to include rotationally symmetrical elements, but the snap latches and associated shots can also, for example have triangular, rectangular or hexagonal cross section. In place of the swivel lever mechanism for actuating the rear locking device can also a tension element tre ten.
