Abstract
A crampon 3 comprises a main structure 7 and means 12 for the removable connection with a boot 2, wherein the removable connection means 12 comprise engagement means 14 adapted to engage an engagement seat 15 of the boot 2 and an elastically deformable connection structure 18 associated with the engagement means 14. The connection structure 18 is shaped so that, when the crampon 3 is connected to the boot 2, following a predetermined elastic deformation of the connection structure 18, the engagement means 14 disengage the engagement seat 15 of the boot 2.
Description
- It is the object of the present invention a crampon, in particular a crampon adapted for connecting with a boot.
- Crampons are accessories that can be attached in a removable manner to boots, in a manner so as to facilitate the walking of the user who wears them on glaciers, snow or on terrain with similar characteristics. For such purpose, crampons have a main structure equipped with pointed portions suitable for partially embedding into the ground, so as to ensure a suitable grip thereon.
- In order to allow the use of the same boots both in the presence of ice, a condition which generally requires the use of the crampons, and without ice, a condition which generally renders the presence of crampons superfluous, crampons have suitable connection means which allow their connection to and disconnection from the boots.
- An example of crampon-boot kit is disclosed in the document FR 2810212. The disclosed boot comprises two lateral projections which are movable following the operation on a button accessible from the rear of the sole of the boot itself. Such lateral projections engage grooves prearranged in corresponding projecting portions provided on the side of the main structure of the crampon. Between the button and the lateral projections, a mechanism is provided for, arranged inside the sole of the boot in such a manner that a movement of the button obtains a movement of the lateral projections. On the front part, the crampon has a bracket with the function of connection to the toe of the boot.
- Such a kit according to the prior art is nevertheless not free from drawbacks.
- Beyond with a simple conformation of the crampon, a rather complex configuration of the boot is necessary, which, as stated, must be equipped with a special mechanism for actuating the lateral projections.
- The presence of such mechanism naturally leads to a high boot weight, as well as high bulk.
- In addition, the prearrangement of the mechanism involves complex boot construction operations, which inevitably is subjected to not negligible production costs.
- Finally, the mechanism can be subjected to breakage or jams which can lead to the impossibility of application or removal of the crampon during use, with consequent impossibility of use of the kit in some circumstances.
- The object of the present invention is therefore to provide a crampon such to at least partially overcome the drawbacks mentioned with reference to the prior art.
- In particular, the object of the present invention is to provide a structurally simple, light, economical and reliable crampon.
- These and other objects are achieved by means of a crampon according to
claim 1. - In order to better understand the invention and appreciate the advantages thereof, several of its non-limiting, exemplifying embodiments will be described below, with reference to the attached figures, wherein:
-
FIG. 1 is a schematic side view of a kit comprising a boot and a crampon according to the invention; -
FIG. 2 is a schematic side view of a portion of a crampon according to a possible embodiment of the invention; -
FIG. 3 is a schematic perspective view of the portion of the crampon ofFIG. 2 ; -
FIG. 4 is a schematic partial rear view of a boot connectable to a crampon according to the invention. - With reference to the figures, a kit is indicated with 1, which kit comprises a
boot 2 and acrampon 3. Preferably, theboot 2 and thecrampon 3 belonging to the same kit are adapted for being mutually connected. Still more preferably, thekit 1 comprises two boots, one for the left foot and one for the right foot, respectively, and the same number ofcrampons 3, a left crampon adapted for being connected to the left boot and a right crampon adapted for being connected to the right boot, respectively. - The
boot 2 and thecrampon 3 are mutually connectable in a removable manner. In this manner, theboot 2 can be used both in a manner independent of thecrampon 3, and in combination therewith. Thecrampon 3 has the function of allowing the user of thekit 1 to cross over icy or snowy terrain or the like, and it is thus connected to theboot 2 in such circumstances. When the crossing of such zones is not required, thecrampon 3 can be disconnected from theboot 2, which can therefore be used in an entirely autonomous manner, from thecrampon 3. - The
boot 2 has a conformation suitable for receiving the foot of a user and for such purpose it is shaped for substantially following the foot shapes. It has amain body 4 which delimits aseat 5 at its interior for the user's foot. In addition, it normally has a sole 6 and closure means 31 such as to allow an easy insertion of the foot in thefoot seat 5 and its fastening to theboot 2 once this has been put on. The closure means 31 can be variously shaped according to per se known methods (e.g. these can include: belts, strings or mechanical closure means, preferably adjustable). - The
crampon 3 comprises amain structure 7, preferably made of a metal material, still more preferably having a form such as to be adapted and follow the shape of the sole 6 of theboot 2. - According to one possible embodiment, the
main structure 7 of thecrampon 3 includes adjustment means for the adaptation of themain structure 7 to boots of different size (e.g. to boots having different foot size numbers). For such purpose, themain structure 7 of thecrampon 3 can for example comprise arear portion 8 and afront portion 9, movable with respect to each other, so that they can be placed at variable distances from each other. It is observed that in the present description and in the attached claims, the terms “front” and “rear” are referred to the boot and the crampon in their normal use conditions, i.e. when they are worn by the user. The rear portion therefore corresponds to the heel zone of the user's feet, while the front zone corresponds to the toes zone of the user's feet. - In order to make it possible the relative movement of the
rear portion 8 and of thefront portion 9 of thecrampon 3, themain structure 7 preferably includes aconnection bar 10 along which therear portions 8 and thefront portions 9 can slide. There are then provided suitable locking means that are adapted to lock therear portion 8 and thefront portion 9 in a plurality of relative predefined positions. For instance, theconnection bar 10 can be equipped with a plurality ofholes 13, each corresponding to a predefined portion, by means of which, e.g. via a screw, therear portion 8 and/or thefront portion 9 can be locked with respect to theconnection bar 10 itself. Preferably, only therear portion 8 is locked to theconnection bar 10. - In order to ensure the suitable grip of the
crampon 3 on the ground, in particular whether icy or snowy, the latter advantageously comprisespointed portions 11 suitable for embedding therein. According to one possible embodiment, thepointed portions 11 are made integrally with themain structure 7 of thecrampon 3 and, preferably, they are provided both in itsrear portion 8 and in itsfront portion 9. Thepointed potions 11 are preferably distributed along the entire lateral periphery of themain structure 7 of thecrampon 3. - In order to allow the removable connection between the
boot 2 and thecrampon 3, the latter comprises suitable removable connection means 12. The removable connection means 12 include engagement means 14 adapted to engage acorresponding engagement seat 15 of theboot 2. When the engagement means 14 of thecrampon 3 engage theengagement seat 15 of theboot 2, theboot 2 and thecrampon 3 are at least partially connected together. According to one possible embodiment, the engagement means 14 include one ormore pins 16 adapted for being inserted in theengagement seat 15, which preferably includes one ormore grooves 17 adapted for being engaged by the pins themselves. Preferably, there are twopins 16. Analogously, there are preferably twogrooves 17, so that each of thepins 16 corresponds with one of thegrooves 17. Thegrooves 17 are preferably approximately shaped like overturned Ls (FIG. 4 ). - The
crampon 3 comprises aconnection structure 18 to which there are associated engagement means 14, in particular thepins 16. Theconnection structure 18 is elastically deformable and it is shaped in a manner so that, when thecrampon 3 is connected to theboot 2, in particular by means of the engagement of the engagement means 14 in theengagement seat 15, following a predetermined elastic deformation of theconnection structure 18, the engagement means 14 disengage theengagement seat 15 of theboot 2, in particular thepins 16 of thecrampon 3 disengage thegrooves 17 of theboot 2. - In accordance with a possible embodiment, the
connection structure 18 comprises aplate 19 associated with themain structure 7 of thecrampon 3. Preferably, thepins 16 are connected to theplate 18. - As will be clear to the man skilled in the art, the operations of connection and disconnection of the
crampon 3 to and from theboot 2 are based on the elastic deformability of theconnection structure 18, particularly of theplate 19. It is in fact sufficient to act on the latter (e.g. along the arrow P in the figures) in order to cause a deformation thereof such as to cause a movement of the engagement means 14 (consistent with the arrow P), in particular of thepins 16. When thecrampon 3 and theboot 2 are connected, such a deformation is translated into a movement of thepins 16 such that these exit from thegrooves 17 of theboot 2. - The deformability of the
connection structure 18, and in particular of theplate 19, also makes the connection between thecrampon 3 and theboot 2 extremely easy. Indeed, by acting on the plate 19 (still along the arrow P) from its non-deformed status in a manner so as to deform it, thepins 16 move into a position where it is possible to position theboot 2 and thecrampon 3 into a suitable position for their coupling. By releasing theplate 19, one obtains the effect of lessening the elastic deformation (hence the plate deforms in the direction opposite the arrow P), with the consequence that thepins 16 automatically engage thegrooves 17 of theboot 2. - Naturally, the
connection structure 18, and particularly theplate 19, must be shaped in a manner such that the elastic deformation suitable for creating the disengagement of thegrooves 17 by thepins 16 can only occur after the application of a force of a predetermined minimum entity (or greater forces). In other words, theconnection structure 18 and theplate 19 are such that their possible elastic deformations due to the normal use of the kit 1 (e.g. a walk along icy or snowy terrain) does not cause thepins 16 to disengage thegrooves 17. Conversely, in order to obtain such effect, the user must operate on theconnection structure 18 and on theplate 19 with a predetermined minimum intensity, beneath which the disengagement does not occur. - As will be clear to the main skilled in the art, therefore, the crampon according to the invention allows a coupling as well as an uncoupling with the boot that requires extremely simple operations. Since it is not necessary to provide for special mechanisms; as occurs instead in the kits according to the described prior art, the overall weight and bulk of the kit is limited, that greatly improves the handling and the transportability of the kit. Finally, the connection system at the base of the described crampon is structurally very simple—and therefore economical—and is very unlikely to fail. Hence, also the reliability of the kit according to the present invention results thus increased.
- In accordance with one possible embodiment, the engagement means 14 and the
connection structure 18, in particular thepins 16 and theplate 19, are arranged at the rear in themain structure 7 of thecrampon 3. In this manner, the boot is engaged at the rear part and for such purpose also the engagement seats 15, and in particular thegrooves 17, are advantageously arranged at the rear of theboot 2, preferably at the rear of the sole 6 of theboot 2. - The connection system so far described allows the mutual coupling of the
boot 2 and thecrampon 3 only at thepins 16 andgrooves 17. In order to make a still more stable coupling, there are advantageously provided second removable coupling means 20 between theboot 2 and thecrampon 3. According to a possible embodiment, such second connection means 20 include abracket 21, preferably connected with thecrampon 3, still more preferably connected in a rotatable manner thereto, adapted to locally constrain the boot. For instance, the bracket can be arranged in thefront portion 9 of the crampon, and be rotatable with respect thereto around an axis orthogonal to the longitudinal axis L of thecrampon 3. In this manner, thebracket 21 may block the front part of the boot. For instance, thebracket 21 can lock theboot 2 at a projectingportion 22 of theboot 2, preferably made from the sole 6, laterally projecting from theboot 2 at least from the front. - Advantageously, the
plate 19 is made of metal material and still more preferably it has a thin thickness. With the expression “thin thickness”, it is intended that theplate 19 has a transverse extension much less than the extension of its other main dimensions. Such conformation allows to obtain the desired elastic deformability of theplate 19 toward predetermined stresses of the user, according to that described above. Theplate 19 may also have sized weak zones so as to give them the desired elasticity. For instance, theplate 19 can include one or moreweak holes 23 made for such purpose. - Preferably, the
plate 19 is extended in a direction such as to partially cover the zone of the heel of the boot 2 (FIG. 1 ). - In accordance with an embodiment not illustrated in the figures, the
plate 19 is connected in a substantially rigid manner to themain structure 7 of thecrampon 2. In this manner, if the movements due to its elastic deformability are excluded, the plate substantially cannot carry out movements with respect to themain structure 7 of thecrampon 3. - According to a further possible embodiment, the
plate 19 is instead movable with respect to themain structure 7 of thecrampon 3. More particularly, theplate 19 is movable with respect to themain structure 7 between a work position and a rest position. The work position corresponds to the position of theplate 19 suitable for the engagement of theengagement seat 15 of the boot by the engagement means 14. The rest position instead corresponds with a position in which such engagement is not allowed, but in which the bulk of thecrampon 3 due to theplate 19 is small, since theplate 19 is no longer situated in a position such as to be able to enclose the heel of the boot at the rear. For instance, in the rest position of theplate 19, it can be arranged substantially aligned with the longitudinal axis L of thecrampon 3. For such purpose, themain structure 7 of thecrampon 3, in particular itsrear portion 8 to which theplate 19 is preferably associated, may comprise a housing hole adapted to partially receive theplate 19 when this lies in its rest position. - The mobility of the
plate 19 with respect to themain structure 7 of thecrampon 3 can be achieved according to various modes. - In accordance with one possible embodiment, the
plate 19 is rotatable with respect to themain structure 7, in particular with respect to itsrear portion 8, preferably overturnable with respect thereto. For such purpose, theplate 19 can be hinged to therear portion 8 of the crampon, e.g. in two points, so that it is rotatable (along the arrow F ofFIG. 3 ) around a rotation axis R preferably orthogonal to the longitudinal axis L of thecrampon 3. - The
plate 19 is advantageously shaped so that, when it lies in its work position, alower portion 25 thereof abuts against arear abutment portion 26 of therear portion 8 of thecrampon 3, and when it lies in its rest position, anupper portion 27 thereof abuts against afront abutment portion 28 of therear portion 8 of thecrampon 3. In this manner, it is ensured that there is limited movement of theplate 19 between the rest position and the work position. When theplate 19 is in work position, the abutment of thelower portion 25 of theplate 19 on therear abutment portion 26 of therear portion 8 of thecrampon 3 ensures that the elastic bending substantially occurs in its further parts with respect to thelower portion 25. - In order to ensure an even higher stability to the connection between the
crampon 3 and theboot 2, the plate may comprise one or more, preferably twoopenings 29 for the passage of astrip 30 intended to wrap around theboot 2. - From the above description, the man skilled in the art will be able to appreciate that the crampon according to the invention allows a connection to and a disconnection from the boot that is quick and easy, corresponding with structurally simple connection means.
- The relative connection between the crampon and the boot is reliable and their lightness and manageability qualities are not compromised.
- The man skilled in the art will further appreciate that, thanks to the shape of the crampon, particularly complex working operations of the boot and/or crampon are not required in order to prearrange the means for the mutual connection. Consequently, also the costs for their working are reduced.
- To the above described embodiments of the crampon, the man skilled in the art will be able to make numerous additions, modifications or substitutions of elements with other functionally equivalent elements, in order to meet specific contingent needs, without however departing from the scope of the following claims.
