    • A63C9/00—Ski bindings

Definitions

  • the subject of the present invention is a device for mounting a safety binding on a ski, comprising a stop and a heel piece independent of each other.
  • a safety binding is mounted on a ski, directly in contact with the upper face thereof.
  • the evolution of the ski manufacturing technique has led to the production of skis and in particular slalom skis whose width in the skate area is narrower than previously.
  • the skate area serving as a support for a ski boot the latter extends laterally, on either side of the ski, which results, in a steep slope, by a support of the boot on the snow even before the corresponding edge of the ski has bitten the snow, causing the ski to slip, which could cause an imbalance or even a fall of the skier.
  • Another solution consists in equipping a ski with two independent wedges, each fixed on the upper face of the ski and used for mounting the stop and the heel of the binding respectively. If a clamping does not occur along the length of the binding area, as in the previous case, it occurs, taking into account the distance of the stop and heel piece from the ski surface, greater than that which the we know in a direct mounting on the ski, an increase in the rocking force of the binding due to the high support of the boot on the binding, which results in an increase in the camber of the ski, that is to say ie by an increase in the deflection of the ski modifying the behavior of the latter.
  • the object of the invention is to provide a device for mounting a stop and a heel piece on a ski, disposed on elevation wedges, without this elevation resulting in an increase in the deflection of the ski.
  • the device which it relates to of the type comprising two wedges fixed to the ski and used for mounting the stop and the heel of the binding respectively, is characterized in that it comprises means of connection between the two wedges, inextensible, that is to say preventing the spacing of the two wedges, while allowing a bringing together of these.
  • the connecting means between the cleats consist of at least one inextensible rod, disposed longitudinally on the ski, above the upper face of the latter and below the face upper wedges, with the possibility of bringing the two wedges closer together.
  • At least one of the ends of the rod is mounted in a wedge with the possibility of sliding longitudinally in the wedge and supported against a stop disposed inside the wedge and turned towards the middle of the shoe.
  • each movable end of the rod has an enlarged part, in the shape of a piston, slidingly mounted inside a recess in the shape of a cylinder, the piston delimiting with the cylinder two chambers, including that located on the side of the rod.
  • the hard visco-elastic material can have a Young modulus between 10 9 and 10 10 N / m 2 , while the softer visco-elastic material has a Young modulus between 10 7 and 10 8 N / m 2 .
  • This arrangement makes the system practically inextensible on the side of the hard visco-elastic material, and allows, when the toe and the heel resulting from a deformation of the ski are brought closer together, elastic damping of this deformation by compression of the visco material. - the most flexible elastic.
  • At least one of the ends of the rod is mounted in a wedge with the possibility of tilting with respect to this wedge, either by providing a vertical light in the wedge for the passage of the rod, either by articulation of the rod inside the wedge about a horizontal axis, parallel to the upper face of the ski and transverse to the axis thereof.
  • a pad of visco-elastic material linked to the rod is fixed to the upper face of the ski, substantially halfway between the two wedges.
  • a stud mounted on the ski with the interposition of a plate of visco-elastic material, and comprising a central opening for the passage of the rod with the interposition of a ring of visco-elastic material.
  • the plate works on the extension- (compression) and the ring works on the salient participate in the damping of the deformation movements of the ski, which is entirely favorable since if the ski must not be prevented from deforming, its deformations must be damped to limit parasitic vibrations.
  • the rod is telescopic and each of its two ends is fixed to each of the two wedges.
  • the two parts of the rod engaged one inside the other can be associated with stops of visco-elastic material, as indicated above.
  • the connecting means between the two wedges consist of at least one cable made of an inextensible material.
  • the ends of the cable are rigidly fixed on the shims, or with the interposition of a hard visco-elastic material for at least one of the ends.
  • the cleats are mounted on the upper face of the ski with the interposition of plates of visco-elastic material. These plates can be sufficient on their own to allow an elastic approximation of the wedges, the rod then being mounted without the possibility of sliding with respect to the wedges, or can be implemented in combination with one of the solutions presented above.
  • FIG. 1 represents the central part or skid zone 2 of a ski on the upper face of which are mounted two wedges 3 and 4 respectively, made of a rigid material, and serving for the wedge 3 for mounting a stop 5 and for the wedge 4 when mounting a heel piece 6, the stop 5 and the heel piece 6 being intended to carry out, in a manner known per se, the binding of a ski boot 7.
  • the wedges 3 and 4 are connected by an inextensible rod 8.
  • the front end 9 of the rod 8, which is widened, is anchored inside the wedge 3, while its widened rear end 10, is disposed inside a cavity 12 formed in the wedge 4.
  • the rear end of the rod 8 behaves like a piston 10, while the cavity behaves like a cylinder.
  • the piston 10 bears, on the side of the rod 8, against a rigid stop 13.
  • the ski when in use condition, the ski flexes, as shown in FIG. 3, the rod 8 does not disturb this movement, because its rear end 10 can slide inside the cavity 12, in direction of the back of it.
  • a light 14 is provided for the passage of the rod 8 towards the interior of the wedge 4. It would be possible to replace this vertical light 14 by a horizontal axis transverse to the length of the ski for mounting the front end 9 of the rod 8 inside the wedge 3.
  • FIG. 4 shows an alternative embodiment of the device of Figures 1 to 3, in which the two ends of the rod are mounted with the possibility of sliding respectively with respect to the front wedge 3 and with respect to the rear wedge 4.
  • the cavities formed inside the two wedges and arranged on either side of the ends 9 and 10 respectively of the rod 8 are filled with visco-elastic material.
  • the visco-elastic material 15, placed on the side of the rod is made of a hard material, having a Young's modulus between 10 9 and 10 1 () N / M 2 @ while the visco-elastic material 16 placed on the other side of the ends 9 and 10, is more flexible and has a Young's modulus between 10 7 and 10 8 N / m 2 .
  • the visco-elastic material 15 allows a firm but not entirely rigid support ensuring the limitation of the distance of the wedges 3 and 4, while the visco-elastic material 16, while allowing the wedges 3 and 4 to be brought together during 'A bending movement of the ski, dampens this movement, which is favorable to avoid the vibration of the ski.
  • a stud 18 of visco-elastic material is fixed to the upper face of the ski, substantially halfway between the wedges 3 and 4. When the ski flexes, this stud 18 works in extension-compression, which causes the vibration of the ski to be damped.
  • FIG. 6 shows a variant of the device of Figure 5.
  • a stud 19 made of a rigid material having a central and longitudinal opening 20, in which is mounted a ring 22 of visco-elastic material which encloses the rod 8 and is glued to it in its central part.
  • the stud 19 is fixed to the upper face of the ski by means of a plate of visco-elastic material 23.
  • the plate of visco-elastic material 23 works with extension-compression, while the ring 22 works with shearing .
  • the rod 8 is mounted at its two ends on the wedges 3 and 4 by two hinge pins 24 horizontal, that is to say parallel to the upper face of the ski, and directed transversely to the ski.
  • the two wedges 3 and 4 are, for their part, mounted on the ski with the interposition of a plate 25 of visco-elastic material, the two plates 25 ensuring, during deformation of the ski, taking into account their characteristics, an effect of damping of the ski by shearing because it retains the possibility of sliding relative to the two wedges 3 and 4.
  • the rod 8, the two ends of which are articulated at 24, as indicated previously, is constituted by two telescopic parts 8a and 8b, the part 8a being capable of sliding inside part 8b.
  • FIG. 9 represents a first possibility, according to which the end 26 of the part 8a is capable, when mounting the boot on the ski, of coming to bear against a stop 27, while being susceptible, during a movement for bringing the two wedges 3 and 4 closer together due to a deformation of the ski, to slide inside a cavity 28.
  • the stop 27a is made of a hard viscoelastic material, of a hardness corresponding to that indicated above with reference to the stop 15 of Figure 4, while the cavity 28 is partially filled with a visco-elastic material 29, more flexible than the visco-elastic material 27a, of a hardness comparable to the visco-elastic material 16 defined with reference to FIG. 4.
  • FIG. 11 shows another embodiment of this device, in which the two wedges 3 and 4 are connected to each other by an inextensible cable 30, for example made of stainless steel.
  • the two ends of the cable can be rigidly fixed on the two shims 3 and 4, or alternatively, as shown in FIG. 12, the front end 32 of the cable 30 can be rigidly fixed on the shim 3, while the enlarged rear end 33 of the cable 30 can bear against a visco-elastic material 34 of high hardness.
  • FIG. 13 when the ski deforms in a direction of approach of the wedges 3 and 4, the cable 30 relaxes, thus in no way harming the behavior characteristics of the ski.
  • the invention brings a great improvement to the existing technique by providing a device of simple design, making it possible to raise the mounting surface of the front stop and the heel of a ski, while avoiding to give this ski an excessive arrow modifying its behavior.
