Definitions

  • the invention relates to a set of triggerable bindings for retaining the two boots of a skier on the same gliding board, in particular, but not exclusively, a snowboard or a monoski.
  • Non-triggerable type bindings are known which are capable of retaining a shoe on a gliding board, without the possibility of tripping. These bindings do not allow the skier to practice this sport safely because, in the event of a fall, there is no possibility of shoe release.
  • bindings of the triggerable type which are capable of releasing the boot when it exerts on the binding which retains the stress exceeding a predetermined threshold.
  • bindings of the triggerable type which are capable of releasing the boot when it exerts on the binding which retains the stress exceeding a predetermined threshold.
  • the invention relates to a set of triggerable bindings for gliding boards in which the release of a shoe, following excessive stress, results in the release of the other shoe.
  • One of the aims of the present invention is to provide a device which connects, in a triggerable manner, the two boots of a skier on a gliding board, the relaxation of a boot furthermore causing the release of the other boot.
  • Another object of the present invention is to provide a device which requires a limited number of operations to make it ready for fitting, after releasing the two shoes.
  • Another object of the invention is to propose a device in which the release of a shoe exerts an action directly on the energy which retains the other shoe.
  • a gliding board 1 which is a snowboard. It goes without saying that this is not limiting, and that the invention also applies to other gliding boards on which the two feet of the skier are held, for example the monoski which is a gliding board on which the two feet of the skier are held side by side.
  • Two individual fastening members 2 and 3 are fixed to the south 1 by any appropriate means, and in particular by screwing.
  • the individual fastening members 2 and 3 are intended to retain the skier's rear and front boots respectively.
  • the individual fastening members 2 and 3 can be mounted on the surfboard 1 according to variable orientations. Preferably, they are aligned on the longitudinal axis 4 of the surf 1, but this is not limiting.
  • Each individual member of the binding is in the form of a rectangular housing 5 whose upper surface has an opening 8 (respectively 6 and 7 for the members 2 and 3 of Figure 1).
  • the individual members 2 and 3 are intended to retain, in a triggerable manner, on the surf 1, the intermediate plates such as those represented in FIGS. 2 and 3.
  • Each intermediate plate 9 has a support plate 10, on which the shoe is placed. , which is also equipped with traditional means for retaining the boot, for example a stirrup 11 at the front, and a rear spur 12, with a lever 13 for securing.
  • the intermediate plate 9 has a core 15 which preferably extends in the middle region of the support plate 10.
  • the core 15 has, in cross section, a pointed end 16, and on each side, the core 15 has two recesses 18 and 19 which each have the shape of a cylinder portion in such a way that the width of the core decreases at the level of its recesses 18 and 19.
  • the skier's boots are intended to be retained in the individual fastening members 2 and 3 by intermediate plates similar to plate 9, the cores 15 of the intermediate plates being engaged inside the openings 6 and 7.
  • each individual fixing member comprises, inside its housing 5, two rollers 20 and 21 intended to engage in recesses 18 and 19 of the core 15, thus ensuring a retention of the core and the intermediate plate 9.
  • the radius of the rollers 20 and 21 is preferably less than or equal to the radius of curvature of the recesses 18 and 19.
  • rollers 20 and 21 are mounted in rotation about an axis. This is not, however, limiting, and the rollers could be replaced by stops of complementary shape to the recesses 18 and 19.
  • the axis of one of the rollers is mounted fixed relative to the housing 5, and the axis of the other roller 21 is movable in a horizontal plane, the spacing of the rollers 20 and 21 causing the release of the core 15, and therefore of the shoe.
  • the movable roller 21 is mounted on a support carriage 25, guided inside the housing 5.
  • the other end of the springs 26 and 27 bears against a support plate 30 which is maneuvered by a lever 31.
  • the lever 31 is movable between a closed position ( Figure 5) and an open position ( Figure 8). In its closed position, the lever 31 exerts a thrust on the support plate 30 which causes an elastic stress on the roller 21 in the direction of the roller 20, by means of its support 25 and the springs 26 and 27. The movable roller 21 is then finds himself in an armed position.
  • the lever 31 is held by a trigger 32 which is articulated, and which has a hooked end 33 for retaining the end of the lever 31.
  • the trigger 32 has tilted so that its hooked end 33 releases the lever 31.
  • a spring 35 recalls the trigger 32 in its initial position, that is to say that corresponding to figure 5.
  • Connection means also connect the two individual members of the binding 2 and 3.
  • FIG. 1 These means are shown diagrammatically in FIG. 1 in the form of two flexible connecting elements 40 and 41. These elements are, for example, flexible and inextensible cables guided inside a sheath.
  • the connecting element 40 connects the support carriage 25 of the fixing member 2 to the trigger 32 of the fixing member 3. Conversely, the connecting element 41 connects the support carriage 25 of the member 3 to the trigger 32 of member 2.
  • Figure 5 shows for a fixing member the end of the two connecting elements.
  • the sheath 43 is retained in the wall of the housing 5 by a sheath stop 44, on the side of the support plate 30.
  • the cable 45 guided inside the sheath 43, passes through the wall of housing 5, then the support plate 30, then the spring 27, and finally, it is crimped at its end onto the support carriage 25.
  • the sheath 46 of the other connecting element is retained at the wall of the housing 5.
  • the end of the cable 47 is crimped on the trigger 32 in such a way that a pull on the cable 47 towards the outside causes the tilting towards the opening of the trigger 32.
  • Figure 6 illustrates the case of an accidental release of the fastening member, shown in Figure 4, which caused the release of the shoe and its intermediate plate.
  • roller 21 In the absence of the core 15, the roller 21 has the possibility of approaching the roller 20, which moreover causes the displacement, to the left of the figure, of the support support 25. This movement also produces the placing under pulling of the cable 45. This generates the opening of the trigger 32 of the other individual fastening member, and the release of the other shoe, in the same way as what will now be explained relative to FIG. 7.
  • FIG. 7 it is the other shoe which has been released by its individual fastening member.
  • This relaxation causes the cable 47 to be put under tension in a manner similar to what has been described for FIG. 6; this traction generates the opening of the trigger 32 and the tilting of the lever 31, as can be seen in FIG. 8.
  • the plate 30 moves to the right of the figure, which also causes decompression springs 26 and 27.
  • the roller 21 is biased towards the roller 20 by a decreasing force, and if necessary, which is canceled out.
  • the roller 21 is actuated in the disarmed position. Therefore, at the slightest request, the plate 9 is released from the individual fixing member which retains it.
  • the release of a shoe causes the release of the other shoe by disarming the retaining means which hold this other shoe.
  • FIG. 9 illustrates an alternative embodiment according to which the two connecting elements 40 and 41 constitute the connecting means, and respectively connect a trigger 32 of an individual fastening member to the intermediate plate 9 of the other shoe.
  • the two connecting elements 40 and 41 constitute the connecting means, and respectively connect a trigger 32 of an individual fastening member to the intermediate plate 9 of the other shoe.
  • the boots remain connected to the surf via the connecting elements 40 and 41, which prevents the surf from continuing on its own in the event of the skier falling.
  • the boot is made by placing the intermediate plates in their respective fixing member, then by closing the levers 31 in the closed cocking position, until they are locked by their trigger 32, which actuates the movable rollers 21 in the cocked position.
  • the embodiment of Figure 9 has the advantage that the shoes can be raised in the fasteners 2 and 3 individually, that is to say one after the other. This has an advantage, for example in queues for ski lifts.
  • FIG. 11 represents a variant of the invention according to which the springs, which ensure the return of the movable rollers 21 of the two individual fixing members 2 and 3, are grouped in a central box 50.
  • the movable roller 21 of the member 2 is connected by means of a tie rod 51 to the end of a compression spring 53.
  • the movable roller 21 is connected by a tie rod 52 to a spring 54.
  • the two springs 53 and 54 are substantially co-axial and arranged symmetrically. In addition, it is the inner ends of the spring 53 and 54 which are stressed respectively by the tie rods 51 and 52 so that the movement of the movable roller 21 of one of the members 2 or 3, in the direction of a spacing of the fixed roller 20, produces a compression of the spring 53 or 54 to which it is connected by the tie rod 51 or 52, respectively.
  • each spring 53 and 54 is in abutment against a drawer, respectively 55 and 56.
  • the drawers can be brought closer to each other by a lever 57 which works in the manner of a toggle. This reconciliation of the two drawers 55 and 56 is made against the return force of the two springs 53 and 54.
  • FIG. 11 represents the device in the disarmed position, the lever 57 being in the open position.
  • the springs 53 and 54 push the two drawers 55 and 56 on each side, and at the bottom of the housing 50.
  • the two movable rollers 21 are in the disarmed position.
  • Figure 12 shows the device in normal ski position.
  • the toggle formed by the lever 57 is closed, which brings the two drawers 55 and 56 closer together.
  • the two springs 53 and 54 are compressed, which elastically urges the mobile rollers 21 of the two fixing members 2 and 3, in the direction of their respective fixed roller.
  • the movable rollers 21 are actuated in FIG. 12 in the armed position.
  • Figure 14 schematically illustrates the set of bindings in the normal ski position.
  • the two drawers 55 and 56 are kept apart from each other by a distance D, and the two springs 53 and 54 tend to move them apart from one another.
  • FIG. 15 illustrates the case where one of the intermediate plates 9, for example that of the member 3, is released.
  • the movable roller 21 of the member 3 approaches the fixed roller by a distance C.
  • This approximation allows each spring 53, 54 to relax by C / 2, which moreover causes the disarming of the roller mobile 21 of the other fixing member 2.
  • the intermediate plate 9 of this other member 2 can then be released following a very low stress.
  • the closed position of the lever 57 is a stable position.
  • FIG. 16 represents a variant according to which the tie rods 51 and 52 are replaced by flexible connecting members.
  • FIG. 16 represents a cable 61 which connects the support 25 of the movable roller 21 to the inner end of its return spring 53, the cable being moreover guided inside a flexible sheath 60 between the outlet of the housing 5 of the fixing member and the inlet of the central box 50. Only part of the fixing assembly is shown in FIG. 16.
  • FIG. 17 represents another variant according to which the lever 59 is locked by a trigger 32 similar to that which has been described in relation to FIG. 5.
  • the closed position of the lever is an unstable position, and this is the trigger 32 which ensures its locking in the closed position.
  • a flexible link 71, 72 also connects each intermediate plate 9 to the trigger 32. In this way, in the event of an accidental fall, and the release of one of the intermediate plates 9, not only the retaining means which hold the other intermediate plate are disarmed, but also by means of one or other of the cables 71, 72, the release lever 59 is also actuated in the open position, following the tilting of the trigger 32 in the direction of an opening.
  • the flexible links 71 and 72 still connect the skier's feet to the surf after the skier has fallen, which can prevent the surf from continuing its course.
  • FIG. 19 shows a variant according to which it is the shoe itself which is retained between the stops 20 and 21 respectively mobile and fixed.
  • stops retain the shoe sole 90, at the recesses 91 and 92, similar to the recesses 18 and 19 of the intermediate plate 9 of the preceding figures.
  • the difference with the above is that the initial spacing of the stops 20 and 21 is greater since it corresponds substantially to the width of a shoe sole.
