    [0001] 1. Field of the Invention [0001]
    [0002] The present invention relates to the field of devices for retaining a boot on a gliding board, and relates more particularly to a device for a snowboard. [0002]
    [0003] 2. Description of Background and Relevant Information [0003]
    [0004] Some of the previously known boot-retention devices are provided to retain a flexible boot onto the gliding board and have the following structure. [0004]
    [0005] Such device includes a base and a rear support element, the base having a seat that extends between a front end and a rear end along a longitudinal direction of the device, the base having two lateral edges affixed to the seat, the edges being connected to one another on the side of the rear end of the seat by an arch, the rear support element being journalled on the base along, a substantially transverse journal axis of the device. The boot is retained on the device, for example, by means of straps. [0005]
    [0006] On this type of device, the rear support element, which extends upon contact with the boot at the level of the user's lower leg, generally has a substantial rigidity so that steering is precise. Indeed, a substantially rigid rear support element enables a direct transmission of the steering impulses to the board. [0006]
    [0007] A disadvantage associated with this rigidity is that the impacts to which the board is subject, while being operated, are reflected in the user's leg. This phenomenon occurs during rear supports, i.e., when the user presses with the lower leg against the rear support element. As a result, the user sometime feels a pain in the lower leg. [0007] SUMMARY OF THE INVENTION
    [0008] An object of the invention is particularly to provide a device for retaining a flexible boot upon a gliding board, such as a snowboard, which enables precise steering, and which reduces the repercussion in the lower leg of an impact to which the board has been subject. [0008]
    [0009] To this end, a device for retaining a boot on a gliding board according to the invention particularly includes a base adapted to receive at least a portion of the boot sole and a rear support element provided to ensure rear support of the lower leg, the rear support element being journalled on the base along a substantially transverse Y-Y′ axis of the device, an abutment being provided to limit a rotation of the rear support element along the Y-Y′ axis in a front-to-rear direction, the position occupied by the rear support element, when the front-to-rear rotation is maximum, being a rear position. [0009]
    [0010] In the device of the invention, an elastic mechanism is provided to bias the rear support element in a rear-to-front direction, over a short range, from the rear position. [0010]
    [0011] During rear support with the lower leg, the rigidity of the rear support element generates a nominal deformation of the elastic mechanism. This means that for a usual support of the lower leg on the rear, or dorsal, support element during steering, the elastic mechanism is subject to a given reversible deformation, and transmits the user's supporting forces to the board. [0011]
    [0012] However, if an impact occurs on the board, i.e., if a brief and substantial force is applied to the board, the elastic mechanism then undergoes an additional deformation to absorb the energy resulting from the impact. [0012]
    [0013] As a result, the impact is not, or is not completely reflected in the user's leg. The elastic mechanism plays the role of a shock absorber. An advantage is that the steering of the board is more comfortable while also being substantially precise. [0013] BRIEF DESCRIPTION OF DRAWINGS

    [0020] FIG. 6 is a view similar to FIGS. 4 and 5, but corresponds to yet another situation. [0020] DETAILED DESCRIPTION OF THE INVENTION
    [0021] An exemplary embodiment of the invention is described hereinafter with reference to FIGS. [0021] 1-6.
    [0022] In a known manner, as is understood, for example, by means of FIG. 1, a device [0022] 1 is provided to retain a boot on a gliding board 2, the boot not being shown for reasons of convenience.
    [0023] The device [0023] 1 includes a base 3 and a rear support element 4. The base 3 has a seat 5 that extends between a front end 6 and a rear end 7 along a longitudinal direction L of the device 1.
    [0024] It is to be understood that the longitudinal direction L of the device [0024] 1 is a direction that is substantially the same as the longitudinal direction of the boot when the latter is retained on the device 1.
    [0025] The base [0025] 3 has a first lateral edge 8 and second lateral edge 9 that are provided to retain the boot along a transverse direction of the device 1. It is to be understood that the transverse direction is a direction that is substantially perpendicular to the longitudinal direction L, and substantially parallel to the seat 5.
    [0026] An arch [0026] 10 connects the edges 8, 9 on the side of the rear end 7 of the seat 5. The arch 10 is an edge that is located toward the rear of the device 1, raised with respect to the seat 5.
    [0027] Preferably, the seat [0027] 5, the edges 8, 9, and the arch 10 form an integral piece, which enables the base 3 to be manufactured according to a simple process. For example, the base 3 can be made with a plastic or metallic material introduced in a mold, such as polyamide reinforced with glass fibers.
    [0028] The base [0028] 3 is retained on the board 2 by any means known to the person with ordinary skill in the art, such as a disk 11, for example, which is itself affixed to the board 2 by any suitable means.
    [0029] The boot is removably retained on the base [0029] 3 by a means shown in the form of straps 12, 13, which are also well known to persons with ordinary skill in the art.
    [0030] The straps [0030] 12, 13 hold the boot such that the sole lays flat on the seat 5, and that the heel lays flat on the arch 10 or is located in the vicinity of the latter.
    [0031] The rear support element [0031] 4 has an incurved portion 14, as well as a first arm 15 and a second arm 16 located in the extension of the lateral edges 8, 9, respectively. The rear support element 4 is journalled on the arch 10 along a substantially transverse Y-Y′ axis of the device 1.
    [0032] It is to be understood that the Y-Y′ axis is oriented in the transverse direction of the device [0032] 1.
    [0033] The journal of the rear support element [0033] 4 on the arch 10 is obtained by a means shown in the form of a first screw 17 and second screw 18 each oriented substantially along the Y-Y′ axis, which corresponds to a technique well known to the person with ordinary skill in the art. The first screw 17 is arranged in the area of the first arm 15, and the second screw 18 is arranged in the area of the second arm 16.
    [0034] An adjustable abutment [0034] 19 limits a front-to-rear journal movement, along the Y-Y′ axis, of the rear support element 4 with respect to the base 3. The front-to-rear journal movement is to be understood as being a movement during which an upper end 20 of the rear support element 4 moves away from the front end 6 of the seat 5.
    [0035] A rear-to-front movement is an inverse movement. [0035]
    [0036] The abutment [0036] 19 is shown in cross-section in FIG. 2. The abutment 19 has a toothed sector 21 provided to cooperate with a toothed sector 22 affixed to the rear support element 4, such that the abutment 19 is attached on the rear support element 4 in a selected position.
    [0037] It is possible to move the abutment [0037] 19 closer to or away from a lower end 23 of the rear support element 4 by displacing the sectors 21, 22, one with respect to the other. To this end, it suffices to loosen a screw 24 for holding the abutment 19 on the rear support element 4, to position the sectors 21, 22, with respect to one another, then to tighten the screw 24.
    [0038] According to the invention, an elastic mechanism is arranged in the area of the abutment [0038] 19 to bias the rear support element 4 in the rear-to-front direction. The bias occurs over a short range from a rear position, which is a position occupied by the rear support element 4 when the rotation in the front-to-rear direction is maximum. This phenomenon is explained below.
    [0039] As seen in FIGS. 1 and 2, the elastic mechanism is shown in the form of a wedge or spacer [0039] 25 attached on the abutment 19, the wedge 25 being made of a deformable material in a reversible manner. For example, the wedge 25 can be made of rubber, polypropylene, silicone, or any other suitable material. The hardness of the constituent material of the wedge 25 is preferably close to 80 Shore A.
    [0040] The wedge [0040] 25 has a lower surface 26 provided to rest on an upper surface 27 of the arch 10, as well as an upper surface 28 provided to rest against a lower surface 29 of the abutment 19.
    [0041] The structure of the wedge [0041] 25, considered as such, is shown in FIG. 3.
    [0042] The wedge [0042] 25 is an integral piece that includes a working zone 30, as well as an affixation zone 31.
    [0043] The working zone [0043] 30 is demarcated in thickness by the upper surface 28 and lower surface 26, in length by a front surface 32 and a rear surface 33, and in width by a first surface 34 and a second surface 35. For example, the thickness can be comprised between 3 and 12 mm, the length between 8 and 18 mm, and the width between 15 and 50 mm. As will be better understood subsequently, the working zone 30 can be compressed between the abutment 19 and the arch 10.
    [0044] The affixation zone [0044] 31 is provided to affix the wedge 25 to the abutment 19. The affixation zone 31 is a portion of the wedge 25 that projects with respect to the upper surface 28. The affixation zone 31 is related to a hook that includes a core 36 and a foot 37.
    [0045] As shown in FIG. 2, a groove [0045] 38 is provided in the abutment 19 to receive the foot 37 of the wedge 25. This groove is demarcated especially by an upper surface 39, a lower surface 40, and a bottom 41. The groove 38 is formed on a surface 42 of the abutment 19 at least a portion of which is opposite the rear support element 4.
    [0046] The assembly of the wedge [0046] 25 with the abutment 19 is done by snap engagement of the foot 37 into the groove 38. Preferably, the foot 37 and the groove 38 have dimensions that enable the foot 37 to be retained in the groove 38. Thus, when the user adjusts the position of the abutment 19 with respect to the rear support element 4, as has been explained previously, the wedge 25 remains affixed to the abutment 19.
    [0047] This means that it is possible to move the abutment [0047] 19 away from the rear support element 4 without losing the wedge 25.
    [0048] When the abutment [0048] 19 is in place on the rear support element 4, the latter improves the retention of the wedge 25 on the abutment 19, because it prevents or limits the exit of the foot 37 from the groove 38.
    [0049] The functioning of the device [0049] 1 is explained hereinafter with reference to FIGS. 4-6.
    [0050] The device [0050] 1 is shown in FIG. 4 in a situation where the boot is not supported on the rear support element 4. The latter is in any angular position with respect to the base 3. As a result, the wedge 25 is not in contact with the arch 10.
    [0051] In the situation shown in FIG. 5, the rear support element [0051] 4 is oriented such that the wedge 25 is in contact with the arch 10.
    [0052] This situation corresponds to a usual steering position of the board [0052] 2. The user takes rear supports along the direction of the arrow, i.e., by pressing on the rear support element 4 in a front-to-rear direction. The wedge 25 enables a dampening of support forces.
    [0053] If a supplemental force is exerted on the rear support element [0053] 4, as is the case along the arrow in FIG. 6, the wedge 25 is more substantially compressed.
    [0054] This situation can occur, for example, at the time an impulse is given to perform a jump, during jump landing, by impact of the board [0054] 2 on a rock hidden in the snow, or the like. The supplemental force induces an additional, temporary deformation of the wedge 25, the deformation enabling a dissipation of the energy generated during the jump or during impact.
    [0055] In other words, it can be said that the wedge [0055] 25 absorbs certain impacts or certain impulses.
    [0056] An advantage associated with the presence of the wedge [0056] 25 on the device 1 is the increased steering comfort.
    [0057] The working zone [0057] 30 of the wedge 25 cannot be compressed beyond a certain limit associated with the characteristics of the constituent material of the wedge 25. When the working zone 30 is in its maximum compression state, the rear support element 4 is in the previously mentioned rear position. The abutment 19 then limits the rotation of the rear support element 4 in the front-to-rear direction. The compression of the working zone 30 occurs over a short range, i.e., over several millimeters.
    [0058] To reassume the position shown in FIG. 5, the rear support element [0058] 4 is biased by the constituent material of the wedge 25. The working zone 30 tends to recover the thickness which it has in the absence of forces or during the usual forces.
    [0059] When the wedge [0059] 25 has reassumed its initial shape, it no longer biases the rear support element 4 in the rear-to-front direction.
    [0060] The invention is not limited to the particular embodiment described hereinabove, and includes all of the technical equivalents that fall within the scope of the following claims. [0060]
    [0061] In particular, other embodiments of the wedge, or other means for affixing the wedge to the abutment can be provided. For example, adhesive or duplicate molding could be used. [0061]
    [0062] Furthermore, one can provide the wedge to be affixed to the arch, the abutment remaining affixed to the rear support element. [0062]
    [0063] One could also provide that both the abutment and wedge be affixed to the arch. [0063]
    [0064] Furthermore, wedge and abutment structures can be provided such that the deformable material of the wedge is biased in traction, in shearing, or the like. [0064]
    [0065] Still, it can be provided that the elastic mechanism is not a deformable wedge but a spring. [0065]
    [0066] In this case, the spring could be positioned in the same area as the wedge, or somewhere else. A non-limiting example consists of housing the helical spring in an oblong hole of the abutment, such that the abutment can move elastically to dampen impacts. [0066]
    [0067] The instant application is based upon the French Patent Application No. 99 15849, filed Dec. 13, 1999, the disclosure of which is hereby incorporated by reference thereto in its entirety, and the priority of which is hereby claimed under 35 U.S.C. §119. [0067]
