Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to the field of bindings for gliding boards and relates more particularly to a support plate for such a binding. It is used in sliding sports, in particular downhill skiing or ski touring.

STATE OF THE ART

Bindings for shoes on gliding boards generally comprise at least one retaining element, configured to hold the shoe on the gliding board, and a support plate on which the sole of the shoe rests, when 'it is engaged with the retainer. The support plate comprises a frame, fixed to an upper face of the gliding board, and a support plate on which the sole of the boot rests.

There exist, on the market, support plates comprising a rubber damping plate interposed between the frame of the support plate and the upper surface of the ski. This construction thus makes it possible to provide flexibility and elasticity to the shoe support. However, this stiffness is not adjustable.

It is also known from the document EP 0595170 a support plate comprising a frame, a support plate, one end of which is connected to the frame by means of an elastically deformable zone and a wedge making it possible to adjust the support stiffness. Said backing plate can have two configurations, a flexibility configuration and a hardness configuration, thus making it possible to adapt the behavior of the binding to the wishes of the user. The latter can thus privilege the damping and its comfort by choosing the configuration of flexibility, or on the contrary, it can privilege the reactivity and the precision of the control of the board of gliding by choosing the configuration of hardness.

In the flexible configuration, under the effect of a vertical force, the support plate is able to effect a downward movement as far as a stop, by bending the elastically deformable zone. The rigid configuration is obtained by blocking the bending movement and therefore immobilizing the backing plate. Blocking is achieved by means of a wedge acting as a stop between the support plate and the frame. The change from one configuration to another is carried out by pulling or turning the cleat, for example with a screwdriver.

This support plate, however, has drawbacks. In particular, when using the support plate in a flexible configuration, the successive deformations of the deformable region can cause fatigue in said zone, or even its rupture, limiting the stability of the rigid and / or flexible behavior over time. or even the lifespan of the ski binding.

The aim of the invention is to provide a support plate for a binding for a gliding board having improved robustness compared to the solution described above. Another object of the present invention is to provide a solution for adapting the behavior of the binding, in particular the support stiffness of the boot on the support plate, while exhibiting stable behavior over time.

The other objects, features and advantages of the present invention will become apparent on examination of the following description and the accompanying drawings. It is understood that other advantages can be incorporated.

SUMMARY OF THE INVENTION

• un châssis destiné à être fixé sur une face supérieure d'une planche de glisse, le châssis portant une surface d'appui destinée à être en contact avec une partie inférieure d'une semelle d'une chaussure,
• une plaque d'amortissement destinée à être en partie au moins intercalée entre une première portion d'une surface inférieure du châssis et la face supérieure de la planche de glisse.

To achieve this objective, the invention relates to a support plate for fixing a sliding device, the support plate comprising:

• a frame intended to be fixed to an upper face of a gliding board, the frame carrying a bearing surface intended to be in contact with a lower part of a sole of a shoe,
• a damping plate intended to be at least partly interposed between a first portion of a lower surface of the frame and the upper face of the gliding board.

• une configuration de dureté pour laquelle une partie de transmission de la cale se positionne en regard d'une deuxième portion de la surface inférieure du châssis,
• une configuration de souplesse pour laquelle la partie de transmission de la cale se positionne en regard d'une troisième portion de la surface inférieure du châssis, la troisième portion étant en retrait par rapport à la deuxième portion.

The support plate comprises a wedge made of a material which is less compressible than the material constituting the damping plate, the wedge being movable between at least:

• a hardness configuration for which a transmission part of the wedge is positioned opposite a second portion of the lower surface of the frame,
• a flexible configuration for which the transmission part of the wedge is positioned opposite a third portion of the surface lower frame, the third portion being set back relative to the second portion.

Thus, the hardness configuration allows the force between the boot and the gliding board to be transmitted mainly via the cleat without damping, which allows more control to be provided to the user. In the flexible configuration, because the third portion is recessed, the transmission portion of the wedge can freely deform / move. This has the effect of inhibiting the effect of the wedge. Thus, the force is mainly transmitted to the damping plate which at least partially dampens it, which makes it possible to provide more comfort to the user. In addition, the hardness and flexibility configurations of the support plate are obtained by transmission of the force mainly via the compression of a more or less hard material. The risk of fracture of the material is therefore minimized compared to a transmission of the force via a bending of an elastically deformable material as proposed in the document. EP 0595170 mentioned above. Thus, the robustness and the stability over time of the hardness and flexibility configurations are improved.

Optionally, the invention may further exhibit at least any one of the following features.

According to one example, the wedge, the damping plate and the frame are arranged so that, in its hardness configuration, the wedge is positioned relative to the frame so that, when a vertical force is exerted, typically by the sole , the frame, retransmits the force to the upper face of the gliding board, mainly via part of the wedge, inhibiting, at least in part, a compression of the damping plate between the frame and the gliding board under the effect of this effort.

According to one example, the wedge, the damping plate and the frame are arranged so that, in its flexible configuration, the wedge is positioned relative to the frame so that, when the vertical force is exerted, typically by the sole , the frame transmits the force to the upper face of the gliding board, mainly via the damping plate, inhibiting, at least in part, a compression of the wedge between the frame and the gliding board.

According to one example, the wedge can be mounted in rotation on the frame relative to a vertical axis. According to an alternative embodiment, the wedge can be slidably mounted on the frame in a translational movement in the longitudinal axis or transverse to the upper face of the gliding board, or even a combination of rotational and / or translational movements.

DETAILED DESCRIPTION OF THE INVENTION

In the remainder of the description, use will be made of terms such as “vertical”, “longitudinal”, “transverse”, “upper”, “lower”, “top”, “bottom”, " before behind ". These terms must be interpreted relatively in relation to the normal position of use of a support plate assembled on a gliding board. For example, “longitudinal” is understood to be relative to the longitudinal axis of the gliding board.

We will also use a frame whose rear / front direction corresponds to the X axis, the transverse or right / left direction corresponds to the Y axis and the vertical or down / up direction corresponds to the Z axis.

An example of a support plate 1000 according to the invention will now be described in detail with reference to figures 1 to 5B .

The support plate 1000 according to the present invention is intended to be coupled to a binding of a gliding board 2000, for example a ski. As shown in figure 1 , the binding comprises a front retention element 3000 of a boot and the support plate 1000 according to the invention. The front retaining element 3000 and its assembly to the gliding board 2000, or even to a frame 1200 of the support plate 1000, are known per se. Note that the frame 1200 of the support plate 1000 can also be the frame of the front retaining element 3000. Those skilled in the art will be able to refer to numerous existing solutions.

The support plate 1000 is disposed on an upper face 2100 of the gliding board 2000. The support plate comprises a frame 1200. The frame 1200 comprises a lower surface 1202 oriented opposite the upper face 2100 of the gliding board. glide 2000. The lower surface 1202 is composed of several portions 1202a, 1202b, 1202c and 1202d. The portion 1202d corresponds to the part of the lower surface 1202 intended to be in contact with the upper face of the gliding board. The portions 1202a, 1202b and 1202c are set back relative to the portion 1202d. A portion is "set back" with respect to a reference portion when it is shifted upwards when the frame is mounted on the gliding device. Thus, a housing or recess is created facing the recessed portion, between this portion and the reference portion. The depth of this housing corresponds to the distance between the plane containing the recessed portion and the plane containing the reference portion. In the mode of illustrated embodiment, the first 1202a, second 1202b and third 1202c portions correspond to continuous lower surfaces of the frame 1200. Alternatively, one or more portions may consist of several distinct surfaces having the same depth, that is to say, each one. distinct surfaces characterizing a portion have the same distance between the plane of this distinct recessed surface and the plane containing the reference portion. The reference portion 1202d can also consist of several distinct surfaces. By having portions forming a discontinuous surface or, in other words, a set of distinct surfaces exhibiting the same shrinkage, this makes it possible to obtain a frame with less material and therefore to lighten the part.

The frame 1200 also carries a bearing surface 1110 intended to be in contact with a lower part of a sole of a boot, for example a ski boot.

According to one embodiment, the bearing surface 1110 is supported by a support plate 1100 mounted on the frame. As shown in figure 2 , the support plate 1100 has an upper face corresponding to the support surface 1110. Preferably, this support surface 1110 is configured so as to facilitate the sliding and by way of the insertion of the boot in the element of detention. For example, the bearing surface 1110 is unstructured, or even mainly smooth.

According to a first example, the support plate 1100 is mounted integrally with the frame 1200. For this, the support plate 1100 can be fixed to the frame by any suitable means, such as for example, by one or more screws, by clipping, by gluing or welding.

According to one embodiment, the support plate 1100 can be removably mounted on the upper face 1201 of the frame 1200. This allows, for example, the user to change said plate, and in particular to use support plates. of different heights and / or different hardnesses so that the behavior of the binding is adaptable to add degrees of comfort or control to the user.

According to a particular embodiment, such as that described in figures 2 and 3 , the support plate 1100 is mounted movable in translation on an upper face 1201 of the frame 1200. The direction of translation is transverse to the longitudinal direction of the boot, that is to say the longitudinal direction of the binding or to the sliding machine. This makes it easier to take the boot off transversely. Thus, in the event of a fall, the support plate 1100 can slide on the frame 1200 and limits the retention of the boot inside the binding. The safety of the binding is improved by making it easier to take it off. This construction is conventional and known to those skilled in the art.

According to another example not illustrated, the support plate 1000 does not include a support plate 1100. The sole of the boot is then directly in contact with the upper face 1201 of the frame 1200.

The support plate 1000 also comprises a damping plate 1300 configured to, at least in one configuration of use, dampen at least part of the vertical forces applied by the boot on the support plate 1100 or of the vertical reaction forces. applied by the ground (eg snow or ice) to the shoe. Thus, this damping plate 1300 absorbs part of the shocks between the ground and the shoe, and thus improves user comfort.

The damping plate 1300 is shaped, in particular its material and its thickness, so as to partially dampen at least one force corresponding to a sliding phase with a landing phase on the ground, a braking phase, a phase of evolution in curve or a phase of absorption of a shock due to a relief of the ground. This compression increases with the amplitude of the force exerted.

Preferably, the damping plate 1300 is interposed between a first portion 1202a of the lower surface 1202 of the frame 1200 and the upper face 2100 of the sliding board 2000. The first portion 1202a is set back relative to the portion 1202d of the lower surface of the chassis. According to one embodiment, the first portion 1202a is offset upwards, relative to the portion 1202d, by a distance substantially equal to the thickness e1 of the damping plate. Thus, when the damping plate is placed on the frame, it is positioned in a first housing opposite the first portion 1202a. In this configuration, a lower face 1320 of the damping plate is substantially flush with the portion 1202d of the lower surface 1202 of the frame while the upper surface of the damping plate is in contact with the first portion 1202a of the lower surface of the frame. frame.

According to one embodiment, the damping plate 1300 is at least partially in contact with the upper face 2100 of the gliding board 2000.

The frame 1200 is also suitable for accommodating at least one wedge 1400. This wedge 1400 is made of a material that is less compressible than the material constituting the damping plate 1300. This wedge 1400 can thus be qualified as rigid.

This wedge 1400 is movable relative to the frame between at least two configurations.

A first configuration is a hardness configuration for which a transmission part 1431 of the wedge 1400 is positioned opposite a second portion 1202b of the lower surface 1202 of the frame. The second portion 1202b is set back relative to the portion 1202d of the lower surface of the frame. According to one embodiment, the second portion 1202b is offset upwards, relative to the portion 1202d, by a distance substantially equal to the thickness of the transmission part of the wedge. Thus, when the transmission part 1431 of the wedge 1400 is placed in a second housing opposite the second portion 1202b of the lower surface 1202 of the frame, the lower surface of the transmission part is substantially flush with the portion 1202d of the lower surface. of the frame while the upper surface of the transmission part is in contact with the second portion 1202b of the lower surface of the frame.

In this hardness configuration, the transmission portion 1431 of the wedge 1400 is positioned relative to the frame 1200 so that, when a vertical force is exerted, typically by the sole, the frame 1200, transmits the force to the face. upper 2100 of the gliding board 2000, mainly via part of the wedge 1400, inhibiting, at least in part, a compression of the damping plate 1300 between the chassis 1200 and the gliding board 2000 under the effect of this effort. Thus, in this hardness configuration, the force between the boot and the gliding board 2000, or the force between the ground and the boot, is transmitted via the wedge 1400 without damping, or with a lower damping than when this force is transmitted through the compression plate 1300, thereby providing more control to the user.

A second configuration is a flexibility configuration for which the transmission part 1431 of the wedge 1400 is positioned opposite a third portion 1202c of the lower surface 1202 of the frame. The third portion 1202c is set back relative to the second portion 1202b of the surface lower frame. According to one embodiment, the third portion 1202c is offset upwards, relative to the second portion 1202b, by a distance greater than the thickness of the transmission part of the wedge. Thus, when the transmission part is placed in a third housing facing a third portion 1202c of the lower surface 1202 of the chassis, the lower surface of the transmission part is substantially flush with the portion 1202d of the lower surface of the chassis while the upper surface of the transmission part is spaced from the second portion 1202b of the lower surface of the frame. The transmission part is therefore no longer in contact with the chassis.

In this flexible configuration, the transmission part 1431 of the wedge 1400 is positioned relative to the frame 1200 so that, when the vertical force is exerted, typically by the sole, the frame 1200 retransmits the force to the upper face. 2100 of the gliding board 2000, mainly via the damping plate 1300, inhibiting, at least in part, a compression of the shim 1400 between the frame 1200 and the gliding board 2000. In the flex configuration, the effort between the boot and the gliding board 2000 where the force between the ground and the boot is transmitted via the damping plate 1300 which at least partially dampens it, thus providing more comfort to the user.

Thus, the flexibility configuration of the backing plate 1000 is obtained by transmitting the force mainly through the compression of the material of the damping plate 1300. This allows the backing plate 1000 to generate a stable behavior. over time and to be particularly robust.

According to one embodiment, the damping plate 1300 is made with a material having a hardness less than 80 Shore A. The damping plate 1300 can be made for example of rubber or polypropylene.

According to one embodiment, the wedge 1400 is made of a material that is not very compressible. Thus, the wedge does not or only slightly deform in compression, or not by more than 5% of its thickness, when it is subjected to a compressive force less than or equal to 100 kg. Such a material may, for example, have a modulus of elasticity greater than 2,500 MPa.

Wedge 1400 can be a monolithic part. Alternatively it can comprise, or be formed, of a stack of layers. It can comprise, or be formed, of a matrix optionally embedded in an encapsulant less rigid than the matrix. This may help reduce the weight of Wedge 1400.

The alternate passage from the hardness configuration to the flexibility configuration is effected by manipulating a control member 1410, preferably carried, or formed, by the wedge 1400. The user can thus adapt the configuration of the plate. '1000 support as desired, for example depending on its shape or snow conditions.

Preferably, the control member 1410 is accessible manually by the user, without requiring additional tools. This control organ appears clearly in figures 1 , 2 and 3 . In this example, the control member 1410 is positioned so as to be located under the sole when the boot is engaged with the retaining element 3000 of the binding. This makes it possible to protect this control member 1410 during a sliding phase. This prevents unintentional manipulation of the control member 1410, or even its catching, when using the gliding board, for example during contact between two skis or during an impact. According to an embodiment that is not illustrated, provision can on the contrary be made for the control member 1410 to be accessible by the user even when the boot is engaged with the retaining element. This allows you to adjust comfort or control without having to take your shoes off.

The cooperation between the frame 1200, the damper plate 1300 and the shim 1400 will now be described in detail.

The frame 1200, the damping plate 1300 and the wedge 1400 are arranged so that a movement of the movable wedge 1400, actuated by the control member 1410, makes it possible to selectively obtain one or the other of the hardness or flexibility configurations. This movement of the wedge 1400 can consist of a translation, a rotation, or even a combination of translation and rotation. For example, the movement of the control member 1410, between two “soft” and “hard” stops as illustrated by figure 2 , can induce this movement of the wedge 1400. In the example illustrated, the wedge 1400 is movable in rotation about a substantially vertical axis during a use phase, that is to say most often around an axis substantially perpendicular to the upper face 2100 of the gliding board 2000.

To obtain the hardness configuration, the wedge 1400 is positioned so that at least one transmission part 1431 of the wedge is in contact, on the one hand with the frame 1200, more particularly with the second portion 1202b of the lower face. 1202 of the frame 1200, and on the other hand with the upper face 2100 of the gliding board 2000. The wedge 1400 being made of a material less compressible than the material constituting the damping plate 1300, the force between the boot and the gliding board 2000 or the force between the ground and the shoe is transmitted via the cleat 1400.

To obtain the flexibility configuration, the wedge 1400 is positioned so that at least one transmission part 1431 of the wedge is opposite the third portion 1202c of the lower face 1202 of the frame 1200. This third portion 1202c is far enough from the upper face 2100 of the gliding board 2000 so that the transmission part of the wedge is not in contact with the third portion 1202c when the wedge is in this flexible configuration. Furthermore, at least a portion of the damping plate 1300, called the damping portion, is in contact, on the one hand, with the first portion 1202a of the lower face 1202 of the frame 1200 and, on the other hand, with the upper face 2100 of the gliding board 2000. Consequently, in this configuration, the force between the boot and the gliding board 2000 or the force between the ground and the shoe is transmitted via the damping plate 1300 During this stress, the transmission part 1431 of the wedge will move / deform in the space allocated opposite the third portion 1202c.

Of course, even in the hardness configuration, provision can be made for the lower face 1202 of the frame 1200 to compress, firstly, a portion of the damping plate 1300 and then, in a second step, come into abutment on the wedge 1400. In this case, the shim 1400 does not entirely inhibit the deformation of the damping plate 1300 but inhibits part of it. Depending on the dimensions of the damping plate 1300 and of the wedge 1400, provision can be made for the user to perceive a first damping phase before perceiving a hardness phase.

Preferably, the wedge 1400 comprises a part interposed between the frame 1200 and the damping plate 1300. The wedge 1400 can be contained between the frame 1200 and the damping plate 1300, preferably with the exception of the member of command 1410 accessible manually by the user. Thus, unlike a configuration as described by the document EP 0595170 , the cleat is protected from possible impacts, thus improving the stability of the flexibility and hardness configurations over time.

Furthermore, the wedge 1400 is preferably the only movable element of the assembly formed by the frame 1200, the damping plate 1300 and the wedge 1400. For this, on the one hand, the wedge 1400 is mounted in rotation or in translation. , or mounted so as to allow a combination of translation and rotation, on the frame 1200, more particularly on the lower face 1202 of the frame 1200. On the other hand, the damping plate 1300 is mounted fixed relative to the frame 1200 .

In addition, the damping plate 1300 can be inserted into the frame 1200, more particularly into the first housing 1230a suitable for receiving the damping plate 1300 facing the first portion 1202a of the lower face 1202 of the frame, for example. example as shown in figure 3 . Thus, the frame 1200 protects the shock absorber plate 1300, in particular the upper face of the shock absorber plate 1300, from possible shocks and external attacks such as frost, thus contributing to the strength of the support plate. 1000. Preferably, the damping plate 1300 is entirely covered by the frame 1200, only its edge remaining accessible from the outside once the frame 1200 is mounted on the damping plate 1300.

A structural example of the cooperation between the chassis 1200, the damper plate 1300 and the gliding board 2000 is now detailed. As shown in figure 3 , the chassis 1200 comprises on its lower face 1202 a fourth portion 1202d, designated the contact surface, for example located at the front of the chassis 1200, intended to be in contact with the gliding board 2000. According to one embodiment, the first housing 1230a is of a height substantially equal to the thickness e1 of the damping plate 1300, as illustrated in more detail in figure 4B . For example, the thickness e1 of the damping plate can be between 2 and 5 mm. Thus, at least part of the upper face 1310 of the damping plate 1300 is in contact with the first portion 1202a of the surface 1202 of the first housing 1230a. At least a part of the lower face 1320 of the damping plate 1300 is in contact with the upper face 2100 of the gliding board 2000 because this part of the lower face 1320 of the damping plate 1300 is flush, for example construction, the contact surface 1202d of the chassis.

The first housing 1230a of the frame 1200 may further include means for securing 1234a and 1234b of the frame 1200 to the plate damping 1300. Alternatively or in combination, the damping plate 1300 may include means 1350 for securing to the frame 1200. According to the embodiment illustrated in figures 2 and 3 , the securing means 1234a and 1234b of the frame 1200 are configured in a complementary manner to the securing means 1350 of the damping plate 1300. For example, the damping plate 1300 comprises at least one opening 1351, more particularly two openings , complementary to at least one relief of material 1234a disposed in the first housing 1230a of the frame 1200, facing the at least one opening 1351. The damping plate 1300 may also include at least one lug 1352, more particularly two lugs 1352, each lug 1352 being complementary to at least one assembly hollow 1234b, for example a blind hole, arranged in the first housing 1230a facing said at least one lug when the plate damping 1300 is mounted on the frame 1200. These securing means facilitate the positioning of the damping plate 1300 relative to the frame 1200 and their maintenance.

A structural example of the cooperation of the shim 1400 with the frame 1200 and the damper plate 1300 is now detailed. The movable wedge 1400 is mainly interposed between the frame 1200 and the damping plate 1300. In order to guide the movement of the wedge 1400, the frame 1200 can include a raised element 1231, the wedge comprising a profile 1330 complementary to this element. in relief 1231. In the example illustrated, the movement of the wedge 1400 being a rotation, provision can be made for the element in relief 1231 to have a substantially circular section and for the wedge 1400 to have an opening 1420 complementary to this section and to the interior of which the relief element 1231 fits. Thus, the element in relief 1231 acts as a shaft on which the wedge 1400 is mounted in rotation.

The dimensions of the circular relief element 1231 are preferably chosen so as to allow the rotation of the wedge 1400 while minimizing its lateral movements. For example, the diameter of the relief element 1231 is less than the diameter of the opening 1420 so that there is a small clearance between the relief element 1231 and the opening 1420. Furthermore, the thickness of the element in relief 1231 is preferably greater than the height of the walls of the opening 1420, and less than the sum of the height of the walls of the opening 1420 and the thickness e1 of the damping plate 1300. The damping plate 1300 comprises, according to this example, a circular opening 1330 suitable for being disposed around the raised element 1231. Likewise, the diameter of the circular opening 1330 of the damping plate 1300 is preferably chosen so that there is a small clearance between the element in relief 1231 and the circular opening 1330.

More particularly, the element in relief 1231 is arranged in a lower recess 1230 of the frame, suitable for at least partially receiving the wedge 1400, and configured so as to allow movement of the wedge 1400.

In the illustrated embodiment, this relief element 1231 is supported by the frame 1200. Alternatively, the construction is reversed, the relief element is a part of the wedge and the frame includes a hole to receive the relief element. of the hold. According to another embodiment, provision can be made for the wedge 1400 to be guided by the damping plate 1300. In this case, it is the latter which bears the element in relief 1231.

According to an embodiment not illustrated, the device comprises fixing means making it possible to hold the wedge 1400 assembled on the frame 1200. For example, this assembly can be carried out by clipping. The frame 1200 and / or the wedge 1400 can carry an elastic tab or an elastically deformable element.

The lower recess 1230 comprises the first 1230a, second 1230b and third 1230c housings located respectively in the first 1202a, second 1202b and third 1202c portions of the lower face 1202 of the frame 1200. The lower recess 1230 also comprises a fourth housing 1230d to contain the body of the wedge with the exception of the transmission part 1431.

In this example, the first 1202a, second 1202b portions of the lower face 1202 of the frame 1200 are at the same level, in other words, the second portion 1202b is flush with the first portion 1202a.

The third housing 1230c is intended to constitute a housing for deactivating the transmission of the force, in a flexible configuration. For this, in the flexible configuration, the third housing is intended to be opposite at least one transmission part 1431 of the wedge 1400, so that this part of the wedge is not in contact, according to a direction orthogonal to the main plane of the support plate 1000, with the frame 1200. The depth of this third housing, that is to say, the distance between the plane containing the portion 1202d and the plane containing the portion 1202c, is therefore chosen so as to prevent the wedge 1400 from being brought into contact, in a direction orthogonal to the main plane of the support plate 1000, with the frame 1200, when a force is exerted, and in particular during a possible deformation of the frame 1200. At least, during a first phase where the force is exerted .

Adjoining the third housing 1230c, the second housing 1230b is intended to constitute a housing for activating the transmission of the force, in the hardness configuration. For this, at least a second portion 1202b of the lower face 1202 of the frame is intended to be facing at least one transmission part 1431 of the wedge 1400, so that the wedge 1400 is in contact, in a direction orthogonal to the main plane of the support plate 1000, both with the frame 1200 and the upper face 2100 of the gliding board 2000.

According to an embodiment illustrated by figure 3 , the lower recess 1230 comprises four second 1230b and third 1230c housings, arranged radially around the axis Z along which the wedge 1400 rotates, that is to say in this non-limiting example, around the element in relief 1231. Preferably, part of the third housings 1230c forms a recess of the frame, between the portion 1202b and the portion 1202c of the lower face 1202 of the frame, which does not open onto the side walls 1203 of the frame 1200. The same is true for the fourth housing 1230d adapted to receive the body of the wedge. This makes it possible to protect the hold 1400, in particular from external attacks such as frost, snow or earth which could become lodged on the hold 1400 and prevent the latter from moving.

A structural example of the wedge 1400 is now described. The wedge 1400 comprises the control member 1410 as well as at least one effector element for the transmission of the force in the hardness configuration. According to the embodiment illustrated in figure 3 , the control member 1410 is connected to a ring forming the opening 1420 suitable for being disposed around the element in relief 1231 of the frame 1200, by a section of material located in the same plane as the ring. The at least one effector element for the transmission of the force in the hardness configuration comprises at least one elastic tab 1430 connected to the ring, and the distal end 1431 of which is made from a non-compressible material. In this example, the distal end 1431 corresponds to the transmission part of the wedge. According to a variant, the elastic tab 1430 is made from an elastic and non-compressible material, deformable in bending. According to the example shown in figure 3 , the wedge 1400 comprises four elastic tabs 1430, possibly interconnected, for example by a bridging element 1440, so as to improve the strength of the wedge 1400.

In order to allow the passage between one or the other of the configurations of the support plate 1000, the wedge 1400 and the damping plate 1300 are, for example, structurally arranged as follows. The at least one elastic tab 1430 is configured so as to fit into an opening 1340 of the damping plate 1300. In this way, the end 1431 of each elastic tab 1430 is able to be in contact with the face. upper 2100 of the gliding board 2000, regardless of the configuration of hardness or flexibility of the support plate 1000. Furthermore, the opening 1340 of the damping plate 1300 may be suitable for allowing the movement of the elastic tab 1430, induced by the movement of rotation, translation, or even the combination of rotation and translation, of the movable wedge 1400, as illustrated for example in the figure 4A . In addition, the thickness e2 of the end 1431 of the elastic tab 1430 can be substantially equal to the thickness e1 of the damping plate 1300, as illustrated in the figure. figure 4B .

A structural example of the configurations, respectively of hardness and flexibility, is now described. Consideration is given to the particular embodiment according to which the support plate 1000 is configured so as to allow a rotational movement around the Z axis of the wedge 1400, comprising four elastic tabs, as illustrated in the figures 4A to 5B .

As shown in figure 4A and 4B , in hardness configuration, the distal end or transmission part 1431 of each elastic tab 1430 is disposed in a second housing 1230b, facing a second portion 1202b of the lower face 1202 of the frame. Thus, the ends 1431 of the elastic tabs 1430 are in contact, or very close, on their upper face, with the frame 1200, and more particularly with the second portion 1202b of the housing 1230b, and on their lower face, with the upper face 2100 of the 2000 gliding board.

When a vertical force is transmitted to the support plate 1000, for example applied by a shoe on the support plate 1000, this force is transmitted, by their respective contact surfaces, from the sole of the shoe to the frame 1200 then, from the frame to the wedge 1400 and more particularly to the end 1431 of an elastic tab 1430, and finally, from the wedge up to the upper face 2100 of the gliding board 2000, as represented by the arrows F1 in figure 4B . Therefore, the compression of the damper plate 1300 is inhibited. The force between the boot and the gliding board 2000 is thus transmitted via the cleat with less damping than if the transmission of the force were effected by the damping plate 1300, or even without damping, making it possible to provide more control to the user.

As shown in figures 5A and 5B In the flexible configuration, the elastic tabs are arranged in a third housing 1230c, facing a third portion 1202c of the lower face 1202 of the frame. Thus, the ends 1431 of the elastic tabs 1430 are each facing a third portion 1202c of the lower face 1202 of the frame. However, a space separates the upper face of the transmission parts of the third portion 1202c.

When a vertical force is transmitted to the support plate 1000, for example applied by a shoe on the support plate 1000, this force is transmitted, by their respective contact surfaces, from the sole of the shoe to the chassis 1200 then, from chassis 1200 to the damping plate 1300, and finally, from the damping plate to the upper face 2100 of the gliding board 2000, as represented by the arrows F2 'and F2 "in figure 5B . This force either does not pass through the wedge 1400 (arrows F2 '), or passes through the wedge 1400 and the damping plate 1300 (arrow F2 "). Whatever the path of the force (F2' or F2) "), the force between the boot and the gliding board 2000 is transmitted in a damped manner by the damping plate 1300, thus providing more comfort to the user.

In addition, as each elastic tab 1430 is flexibly deformable, the mechanical stresses that can be exerted on the wedge 1400, during its movement between one and the other of the configurations, are minimized. In particular, the mechanical stresses are minimized during the insertion of the end 1431 of the elastic tab 1430 between the surface 1202 of the housing 1230 of the frame 1200 and the upper face 2100 of the gliding board 2000, for the passage in configuration of hardness as shown in figure 4B . During this passage, the leg elastic 1430 can slide on the wall of the housing 1230 of the frame 1200 by deforming elastically.

According to a particular embodiment, indexing elements can be incorporated into the support plate 1000 so as to stabilize one and / or the other of the configurations. According to the example shown in figure 3 , the wedge 1400 may include at least one indexing lug 1450, intended to fit into at least one additional indexing hollow 1235 made in the frame 1200, or even in the fourth housing 1230d of the frame. When the wedge 1400 is in the hardness configuration, at least one indexing lug 1450 can be inserted into a corresponding indexing hollow 1235. Likewise, when the wedge 1400 is in the flexible configuration, the at least one indexing pin 1450 can be inserted into a corresponding second indexing hollow 1235. In this example, the wedge comprises two indexing lugs 1450 for four indexing hollows 1235. The wedge 1400 is thus indexed in rotation, thus allowing the user to check that he has actually brought the wedge 1400. in the desired position. Furthermore, these indexing means contribute to maintaining the wedge 1400 in this stable position chosen by the user. Other indexing elements can be considered.

It is understood that additional recesses can be made on the elements included in the support plate 1000, so as to limit its weight and thus lighten the binding of the gliding board.

The invention is not limited to the embodiments described above and extends to all the embodiments covered by the claims.

The invention is not limited to these embodiments. It is possible to combine these embodiments.

For example, provision can be made for the damping plate 1300 to be monolithic or not. It can for example be formed from a single material, more compressible than the material constituting the wedge. Alternatively, it can be formed from a stack of layers, of different hardnesses and possibly of different thicknesses. At least one of these layers forms a damping portion and has a lower hardness than that of the wedge.

A stack of layers having different hardnesses can, for example, make it possible to vary the progressiveness of the damping, depending on the amplitude of the vertical force received by the frame 1200. For example, linear damping can be provided or not.

On the other hand, if the damper plate 1300 has a rigid top layer such as a top cover, this can reduce the coefficient of friction between the shim 1400 and the damper plate 1300, even when a force is exerted. by the user. For example when the force is static and limited to the weight of the user, the coefficient of friction between the wedge 1400 and the damping plate 1300 allows and facilitates the displacement of the wedge 1400. The user can then modulate the damping provided by the binding even when the shoe is engaged with the binding. Naturally, it will then be necessary to provide for the control member 1410 to be accessible in the presence of the boot. The thicknesses and materials of the different layers will be chosen so that the damping plate 1300 effectively plays its damping role.

Provision can also be made for the wedge to be movable between more than two configurations, one of the configurations being an intermediate configuration, in which during a first phase the frame partially compresses the damping plate and then comes into abutment on the wedge this which stops the compression of the damping plate. This embodiment makes it possible to offer the user a compromise between the configurations of hardness and flexibility. It provides damping on limited shocks while maintaining precise control of the board.
