Definitions

  • the invention relates to an assembly for retaining a ski boot on a ski, including alpine skiing.
  • a shoe is retained on such a ski by two retaining elements front and rear which releasably grip the front and rear end pieces of the shoe.
  • one at least one of the retaining elements is movable along a slide, and its position along the slide can be adjusted using a lock which cooperates with a series of notches of the slide, or other similar device. In general this function is fulfilled by the rear retainer.
  • the rear retainer may still back from its position fixed by the latch against the return force of a spring which is called recoil spring.
  • recoil spring In ski flexion, the ski forms an arc, the shoe which is considered as incompressible forms the bowstring. It is therefore necessary that the body of one of the retainers can move back to allow the ski to flex in good conditions.
  • the recoil spring is housed in the body of the retainer rear, and it is the body of the rear retainer that moves during a movement of decline.
  • Patent application WO 82/03182 describes a retaining assembly where the elements of front and rear retainers are slidably mounted each in a slide united to skiing.
  • An inextensible strip connects the two elements and defines their spacing.
  • the element front is immobilized relative to the ski while the rear element is free to slide in its slide while being retained by the inextensible band and being recalled elastically pushed back by the recoil spring which is housed in the body.
  • Such a device is advantageous insofar as the reaction force which is generated by the thrust of the recoil spring is returned to the front retaining element without passing through ski.
  • the flexing of the ski is therefore less disturbed by the thrust of the recoil spring. He is coming however in the event of strong bending of the ski an intense friction occurs between the body and its slide, which returns constraints in skiing.
  • the two racks ensure a recovery of efforts generated by the recoil spring.
  • An object of the invention is to propose another mode of construction of a set of restraint which provides a better distribution of recoil forces.
  • the restraint system comprises two front retaining elements and rear each comprising a jaw retaining one end of the shoe, a body carrying the jaw and a slide intended to be assembled to the ski along which the body is slidably mounted, a connecting rod connected to each of the bodies, each of the connecting rods being directed one towards the other and having a free end opposite the body to which they are connected respectively.
  • the assembly is characterized by the fact that each of the bodies is mounted freely sliding along its slide and that the two free ends of the connecting rods are mechanically connected to at least one spring mounted so as to provide resistance elastic to a relative spacing of the two bodies.
  • the restraint assembly includes elements 3 and 4 for retaining the front ends and back of a shoe.
  • the front element is of any suitable type.
  • the front element 3 has a jaw 6 carried by a body 7.
  • the jaw is designed to retain the front toe of the shoe, it is movable relative to the body on either side of its position centered on the longitudinal axis of the ski, and it is recalled in this centered position by a spring housed in the body.
  • a support plate 8 connected to the body is provided to receive the shoe sole.
  • jaw could be movable with its body relative to a pivot carried by a base.
  • the rear element 4 also comprises a jaw 10 for retaining the end back of the shoe.
  • the jaw is movable relative to a body 11 around an axis transverse 12 and it is returned to the retaining position by a spring housed in the body.
  • a lever 13 makes it possible to force the jaw to open to release the shoe from voluntarily.
  • the rear element In front of the jaw, the rear element has a support plate 14 designed to receive the shoe sole, and a braking device 15.
  • the elements 3 and 4 are interconnected by an elastically bond stretchable in order to ensure a pinch of the boot and to facilitate the flexing of the ski in its central part.
  • the body 7 of the front element 3 is mounted freely sliding in a slide 16 connected integrally to the ski 1 by any means suitable for example screws, gluing or welding.
  • a front rod 17 is fixed integrally to the body 7 by one of its ends and extends toward the other retainer.
  • the front rod is secured to the body 7 in its longitudinal translational movement.
  • the longitudinal position of the body along of the front rod 17 can be adjusted.
  • the slide includes two rails slide 16a, 16b, each fixed integrally to the ski.
  • the rod has a rectangular section whose height corresponds to the thickness of the lower part of the rails, and whose width is substantially equal to the spacing of the rails. So the two rails leave a space between them which forms a guide groove for the rod 17.
  • a plate sliding 18 is interposed between the rails and at least the rod to facilitate its free sliding.
  • the rails 16a and 16b each have a "C" section, the openings of which face each other, and the body 7 has at its base two projecting side shoes 20a and 20b which are engaged in rails 16a and 16b. In this way the body 7 can slide freely with the rod 17 in slide 16.
  • the rod 17 has a series of notches spaced in a direction longitudinal. Only the notches 21a and 21b which are in the plane of Figure 2 are visible.
  • a lock 25 is housed in the body 7, the lock carries teeth at its base like the teeth 26a and 26b shown in Figure 2.
  • the lock is movable around an axis 28 by an action on its operating pallet 29 between a low position where at least one tooth is engaged with a notch of the slide, and a high position where the teeth are released from the rod.
  • the lock is shown in dotted lines in this last high position.
  • a spring (not shown) resiliently recalls the lock in its low position.
  • the axis 28 is oriented longitudinally, and the pallet 29 is accessible on the side of the body, in front of the support plate 8.
  • the rear retaining element likewise has a rear rod 31 which is solidly connected to the body 11.
  • the body and its rod are free to slide in a slide 32.
  • the construction method is the same as that of the front part, so it will not be described in detail.
  • the slide 32 has two rails 32a, 32b for guiding the lateral runners 33a, 33b of the body, and a latch 35 makes it possible to adjust the longitudinal position of the body along the rod.
  • the two rods 17 and 31 converge towards each other. Their free end penetrates in a central box 36 which is fixed integrally to the ski by any suitable means, in particular by screws, by gluing or welding.
  • the housing 36 is located towards the middle of the two retaining elements, that is to say towards the mid-shoe mark that the ski wears usual way.
  • the housing contains a spring return mechanism whose function is to oppose an elastic restoring force at a relative distance from the front and rear bodies during the engagement of the shoe and during skiing, it being understood that the two bodies can move here.
  • the rods 17 and 31 have at their end an upward fold 17a, 31a.
  • the folds are back to back.
  • Springs 39 and 40 are placed between each of the folds and the wall of the housing. So everyone springs 39 and 40 exert on a fold 17a, 3 la an elastic restoring force which tends to oppose a relative distance from the elements.
  • Each spring rests against a wall of the housing, that is to say on a fixed element on ski. In this way the restoring force which it exerts depends only on its stiffness and its own compression.
  • the springs shown are compression springs, but one could use also tension springs, or a combination of compression springs and traction or any other elastic return means.
  • the springs 39 and 40 are preferably prestressed so that the two folds are resting against each other.
  • FIG. 6 illustrates the fact that each of the springs 39, 40 can in fact be a battery elementary springs 39a, 39b, 39c, 40a, 40b, 40c.
  • the number and arrangement of springs elementary are not limiting.
  • both retaining elements are returned to each other by the spring mechanism housed in the case 36.
  • the rear element does not have a reversing device its own.
  • the construction of the body of the rear element is therefore simplified.
  • the body can be more compact in a longitudinal direction, which facilitates its sliding in the slide.
  • the return springs 43 and 44 rods 45 and 46 have different stiffnesses.
  • the pinching force exerted on the two retaining elements remains balanced by definition, but it is the displacement of each of the bodies that is different. This therefore makes it possible to differentiate one of the elements by a greater displacement.
  • the spring return only includes a spring 50 bearing on one side on the fold 5 la of one of the rods 51 and the other on a wall of the housing 59.
  • the relative movement of the two rods 51 and 52 is synchronized by example by means of a toothed wheel 54 which cooperates with two opposite racks 56, 57 carried by each of the ends of the rods.
  • the toothed wheel pivots about an axis which is mounted fixed relative to the housing 59.
  • the axis of the toothed wheel is oriented transversely to the longitudinal direction defined by the ski. This is not limiting and one could use a toothed wheel with vertical axis as is already known.
  • the displacement of the retaining elements which results from the pinching force is shared between the two retaining elements.
  • the toothed wheel 54 forces the two retaining elements to move in the same way amplitude.
  • the compression stroke of the spring 50 is half the displacement cumulative of the two elements.
  • FIGS. 9 and 10 also calls for a device for synchronization, in this case a disk 62.
  • the ends of the two rods 63 and 64 are superimposed and slide one relative to each other.
  • each rod has a rectangular cutout, respectively 63a, 64a in which is housed the spring 70 bearing against the ends of each of the cuts.
  • the two cutouts 63a and 64a have the same length. In these conditions the spring 70 ensures a relative return of the two rods in the position where the two cutouts are superimposed.
  • Each rod has a lateral extension, respectively 63b, 64b.
  • the two extensions are located on either side of the longitudinal direction defined by the rods.
  • the disc 62 is pivotally mounted on a stud 67 projecting from the bottom of the housing 68.
  • the disc 62 has two rods 62a, 62b diametrically opposite and perpendicular to the plane of the disc which are engaged in oblong slots 63c, 64c of the lateral extensions 63b, 64b.
  • the oblong slots 63c, 64c are positioned relative to the cutouts 63a, 64a a little beyond the middle of the length of the cut, towards the end of the rod.
  • the spring compression stroke is here equal to the cumulative displacement strokes of the two front and rear retaining elements, and the disc ensures synchronized movement of the two elements.
  • a simple slender pad could be used with the two rods and a housing for the stud 67.
  • a device deformable diamond type could be used in this case two opposite vertices of the rhombus would be linked to the rods. The other two vertices would be guided in the case for example in oblong lights directed perpendicular to the longitudinal direction of the rods.
  • a rhombus we could have a symmetrical deformable quadrilateral with respect to the longitudinal direction of the rods.
  • the displacement symmetrical of the two rods 74 and 75 is controlled by a two-stage toothed wheel 76, at the times for adjusting the position of the front retaining elements for skiing, and for toe-in of the boot during skiing.
  • a first stage 77 of the toothed wheel 76 is in engagement with the two racks 79, 80 vis-à-vis that the rods carry at their end.
  • a second stage 81 of the toothed wheel 76 is engaged with a lock 82 for blocking in rotation, the second stage is only partially shown in Figure 11 for reasons of clarity.
  • the lock is operable using a lever 83 accessible from the outside. In one of its positions, the lock is engaged with the stage 81 of the toothed wheel which it immobilizes in rotation, in the other the stage is disengaged in rotation. Preferably it is returned by a spring in its blocking position of the stage 81.
  • the two stages of the toothed wheel 76 are mounted on the same axis of rotation, one above on the other and are connected by a torsion spring 85 located for example in a housing distributed between the two floors.
  • the longitudinal position of the retaining elements can be adjusted by action on the lock 82.
  • the two stages of the toothed wheel rotate together which requires a symmetrical displacement of the bodies.
  • stage 81 Once the stage 81 is locked, the relative movement of the bodies is still possible against the restoring force exerted by the spring 85 which is induced by a rotation of stage 77 relative to stage 81.
  • the case is optional, its main function is to provide the rods and to springs a fixed reference on the ski.
  • Other means may be suitable for this.
  • the spring mechanism could be housed in the front part of a trim piece from one of the slides.
  • the case could have a variable longitudinal position on the ski so as to make it possible to adjust the longitudinal position of the retaining assembly.
