DETAILED DESCRIPTION OF THE INVENTION

[0030] The snowshoe having the general reference number 1 which comprises the mount according to the invention is embodied in the form of an elongated plate having dimensions greater than those of the boot, advantageously cut out, forming frame 2 of the snowshoe, having a general plane P of symmetry and comprising an assemblage of panels supporting mount 3 intended to receive the user's boot CH.

[0031] The frame 2, with its assemblage of internal panels, forms a general lower surface for support on the snow, allowing the user not to sink too deeply into the snow thanks to the large supporting surface having dimensions, in both length and width, greater than the lower surface of the sole.

[0032] According to the illustration shown as an example, the mount 3 intended to hold the boot is hinged with respect to frame 2 of the snowshoe itself along a transverse axis XX′. Additionally, the snowshoe illustrated can be of an entirely different type, for example a central panel made of cloth held by a peripheral framework made of aluminum or of a composite or other material.

[0033] The mount, provided as an example and having the general reference 3, is advantageously constituted by a plate 4 hinged around transverse axis X, X′. The plate 4 comprises holding means for the boot, namely front holding means 5 and rear holding means 6. The front end of the boot is held by the front holding means, for example, a front holding member 7, and its rear end is held by a rear holding member 8.

[0034] It is evident that the plate comprises means for pre-adjusting the longitudinal position of the rear holding member 8, for example those described in the French patents published under numbers FR 2 896 430 and FR 2 760 379.

[0035] The illustrations show a mount implemented in the context of a hinged plate carrying holding means, or, for example, with holding means fastened directly onto the frame.

[0036] According to the invention, at least one of holding members 7, 8 comprises at least one abutment element 11 allowing the corresponding member to be in constrained abutment against the boot in order to hold it. Abutment element 11 can furthermore be an elastic or flexible element such as a strap.

[0037] The flexible, or preferably elastic, abutment element 11 allows the use of any type of boot, of any shape or any stiffness, on a snowshoe mount in accordance with the invention.

[0038] It is understood that an elastic element is a flexible element having the capability of deforming elastically.

[0039] The holding member that has the abutment element is movable between a boot release position as illustrated in FIG. 3 and a boot holding position as illustrated in FIG. 10. The mount comprises actuating means 110 for causing displacement of the holding member from its release position toward its holding position in which the rear holding member is in constrained abutment against the boot. The actuating means comprises a movable part arranged below the region occupied by the boot, and connected at least kinematically to the corresponding holding member. Actuation of the movable part by the boot during attachment causing displacement of the corresponding holding member toward its holding position.

[0040] According to one preferred embodiment illustrated in FIGS. 1 to 10, rear holding means 6, and more particularly, the rear holding member 8, comprise an elastic element 11. According to the embodiment illustrated, rear holding member 8 is therefore constituted by an encasing panel 9 forming a cavity open toward the front (AV), i.e. toward front holding means 5, intended to hold the heel of boot CH. Encasing panel 9 is pivotably mounted on plate 4 around a transverse axis Y, Y′. This encasing panel 9 is constituted by two side panels 10a, 10b and a rear encasing panel 10c. According to this preferred embodiment, rear encasing panel 10c is made of an elastic material in order to constitute elastic element 11. It is this elastic element, constituted by an elastically deformable strip, that is intended to be in constrained abutment against the top rear portion of heel 12.

[0041] “Constrained abutment” is to be understood as an abutment against the boot whose force, in particular directed toward the front of the mount in the present embodiment, ensures retention of the heel of the boot. Encasing panel 9, constituted by the two side panels 10a, 10b and rear encasing panel 10c, is furthermore pivotable on plate 4 around transverse axis Y, Y′. Encasing panel 9 is integral with a rear abutment plate 110 against which the bottom of the heel is in abutment in the attached position. The rear assemblage constituted by rear abutment plate 110, and encasing panel 9 with its elastic element 11, thus form a pivoting assemblage, mounted pivotably on plate 4 around transverse axis Y, Y′, which can assume two positions, namely a boot release position as illustrated in FIG. 3 and a boot holding position as illustrated in FIG. 10.

[0042] In the boot release position as illustrated in FIGS. 3, 4, 4A, 4B and 8, the rear encasing assemblage constituted in particular by rear encasing panel 10c is swung to the rear (AR) with its abutment plate 110.

[0043] In the boot holding position as illustrated in FIGS. 5, 5A, 5B, 6 and 10, rear encasing panel 10c constituted by the elastic element is in constrained abutment against the boot, specifically by the creation of a force toward the front (F) due to the elasticity of rear encasing panel 10c.

[0044] The mount, and in particular its rear holding means 5, comprise means for locking the holding position, and unlocking means allowing a transition from the holding position to the release position.

[0045] It is evident that in order to attach the mount, the latter being in the position illustrated in FIGS. 3 and 8, the user, having engaged the front of his or her boot into front holding member 7, places his or her heel onto abutment plate 110 that is tilted toward the rear (AR) and, by downward pressure in the direction F1, his or her heel causes pivoting of the rear assemblage as illustrated in FIGS. 4 and 8.

[0046] In the course of this pivoting in the direction of R1, encasing panel 9 is displaced rotationally toward the front (AV), which first places elastic element 11 in abutment against rear top portion 12 of the heel, as illustrated in FIG. 9, and then secondly, as the pivoting of the encasing panel ends, elastic encasing element 11 is in constrained abutment with the heel of the boot so that it forces the rear top portion of the heel toward the front (FIG. 10).

[0047] Simultaneously, the attached position is automatically locked in that position. The locking means are constituted for that purpose, for example, by a movable locking part 13 acted upon by an elastic system such as a spring 14 interacting with a fixed part 15.

[0048] As an example, fixed part 15 is integral with rear abutment plate 110 and is a yoke projecting below rear abutment plate 110 in the shape of an inverted T or a U. The yoke comprises a transverse arm 111 intended to be held by movable part 13, as illustrated in FIG. 6.

[0049] The locking means furthermore comprise an unlocking lever 17 hinged on plate 4 around a transverse axis, for example axis Y, Y′ (shown in FIGS. 4A, 4B, 5A and 5B, among others). In addition, unlocking lever 17 extends toward the rear (AR) and upwardly (HA) so that it can be actuated by the user. For example, pivoting end 18 of unlocking lever 17 comprises an actuating ramp intended to push the movable locking part.

[0050] Unlocking lever 17 could extend laterally, for example laterally outward with respect to the boot.

[0051] Movable locking part 13 is a sliding part received in mount plate 4 which comprises at its front end a locking finger 20 intended to interact with transverse arm 111 of fixed part 15.

[0052] FIGS. 7, 8, 9 and 10 are illustrations showing the operation of the mount.

[0053] FIG. 7 shows the boot outside the mount, the mount being illustrated in the attached position but without the boot. It is evident from this Figure that the distance between front end 21 of the boot and rear holding end 22 has a length L that is greater than distance L1 between front holding member 7 and rear holding member 8, with a differential d ensuring that the elastic element presses onto the boot.

[0054] Upon attachment (FIG. 8) the user, acting downwardly with his or her heel onto rear abutment plate 110 causes rear encasing panel 10c, which in this embodiment is elastic element 11, to rotate toward the front in direction R1.

[0055] During this rotation, elastic element 11 constituting rear encasing panel 10c at first simply comes into abutment against rear upper part 12 of the heel, as illustrated in FIG. 9. As the frontward rotation continues, elastic element 11 is forced into constrained abutment against the boot to ensure that it is held.

[0056] At the completion of rotation, locking of abutment plate 110 is accomplished by interaction of movable locking part 13 with transverse arm 111 of fixed part 15. The boot is thus retained by a frontward action (F) of elastic element 11.

[0057] According to the embodiment described and illustrated above, the rear encasing member is brought into abutment in constrained fashion against the boot by pivoting, but this situation could be different. For example, according to the variant illustrated in FIG. 11, the displacement toward the boot in order to bring rear encasing panel 10c into constrained abutment is effected by frontward translational displacement T of rear holding member 8 with its elastic element 11. For this purpose, the means for causing this displacement are constituted by a system of links 25 arranged under the heel of the boot.

[0058] According to a variant that is not depicted, rear panel 10c of rear encasing panel 9 is made of a non-elastic material, while side panels 10a, 10b are made of elastic material. The mode of operation according to this embodiment is the same, except that rear encasing panel 10c is not elastic, but by action of side panels 10a, 10b, which are elastic, the rear encasing panel 10c is in constrained abutment against the boot.

[0059] The preferred embodiment illustrated in FIGS. 1 to 11 is such that it is the rear holding member that comprises the elastic element, but that situation could be different. For example, the front holding member could comprise an elastic element that could exert pressure on the boot in order to ensure that it is held.

[0060] FIGS. 4A and 5A are views similar to FIGS. 4 and 5, illustrating a variant embodiment according to which rear encasing panel 10c is mounted hingedly on each of side panels 10a, 10b around a transverse axis 120. This allows better adaptation to the boot.

[0061] FIGS. 4B and 5B are views similar to FIGS. 4 and 5, illustrating another variant embodiment according to which pivot axis Y, Y′ of the rear holding member is displaced toward the front so it is located farther frontward with respect to rear panel 10c, unlike the previous implementation according to which pivoting axis Y, Y′ is located substantially plumb with the rear portion of rear panel 10c. It is apparent that, with the embodiment of FIGS. 5A and 5B, there will be greater engagement of rear panel 10c against the heel.

[0062] The necessary elasticity can be achieved by the sliding of rear holding element 8 on the plate that carries it, such sliding occurring against the action of an elastic system such as a spring or another system.

[0063] It is evident that attachment and holding of the boot onto and on the snowshoe occurs automatically due to the elastic effect of the elastic element of one of the holding means.
