Definitions

  • the present invention relates to a ski provided with a stop or brake device consisting of at least one stop member articulated on one side of the ski and maintained in an operating position by elastic means and at least one pedal d actuation having the function of raising the stop element in an inoperative position during putting on.
  • the invention also relates to a safety ski binding equipped with such a stop device.
  • the first step of the present invention was to question this conception which has become commonplace.
  • the stop elements or the pedal are not always arranged in the most judicious manner.
  • the binding comprises a detachable under-plate for the ski or pivotally mounted on the ski or a heel pivotally mounted on the ski or on an under-plate.
  • the pedal can hinder the movement of the pivoting part of the binding and also modify the conditions for triggering the binding because of the friction, the greater the amplitude of the sliding.
  • the invention aims to improve the operation of the binding while simplifying the construction of the stop device.
  • the ski respectively the safety ski binding, according to the invention is characterized in that the actuation pedal and the stop element are independent of each other.
  • the brake element and the pedal can thus be each mounted on the element of the binding that is best suited to receive it.
  • the pedal and the stop element are treated separately, it is possible to simplify each of these parts, the pedal being able to consist of a simple plastic plate sliding on a lever arm of the stop element. This sliding friction is easy to control and it can be maintained at very low values.
  • the design of the stop device according to the invention does not only apply to bindings or movable binding parts on the ski, but to any type of binding and has advantages in all cases.
  • Figure 1 is a partial side view of a ski and the rear part of a plate safety binding provided with a stop device, in the released position, in the absence of a boot.
  • Figure 2 is a half view of the same device seen along the axis of the ski.
  • FIGS 3 to 7 schematically show other types of ski binding and other arrangements of the stop device.
  • FIG. 1 represents the rear part of a safety ski binding with a plate as described in detail in patent application FR 2 643 566 of the applicant.
  • an underfoot plate 1 pivotally mounted in its central part on a ski 2 and carrying at the rear, a heel piece 3 provided with a jaw 4 articulated on the heel and intended to hold the heel of a shoe 5.
  • the heel 3 is pivotally mounted on the plate 1 about a vertical axis.
  • each of the stop element 6 is constituted two metal rods 9 and 10 interconnected by a claw 11 made of synthetic material in which the rods 9 and 10 are embedded. Starting from the claw 11, the rods 9 and 10 are first of all rectilinear and left relative to each other. The rod 9 then has a bend 9a followed by an oblique rectilinear intermediate part 9b constituting the axis of articulation of the stop element on the plate 1. This part 9b is followed by a bent part 9c in the form of crank and constituting a lever on which the actuation pedal acts 7.
  • the end 10a of the other rod is also bent and is supported, with a slight pressure, in a cavity 12 formed in the lateral face of the plate 1.
  • the fulcrum of the end 10a is located above below and behind the axis 9b and the light pressure on the stop device keeps it in an oblique position as shown in Figures 1 and 2.
  • the elasticity of the stop element is ensured by the claw 11, but it could be ensured by any other means.
  • the sole of the boot actuates the pedal 7, which, by its concave underside 7a, actuates the lever 9c of the stop element by driving the latter in rotation about its oblique axis 9b.
  • the lateral face of the plate 1 however opposes the free rotation of the rod 10 around the axis 9b forcing the stop element to deform, this deformation being made by the elastic deformation of the claw of synthetic material 11.
  • the cavity 12 further reduces the possibilities of sliding of the end 10a on the lateral face of the plate 1, thus increasing the deformation of the stop element.
  • the stop element Given the orientation of the axis 9b of the stop element, it comes to be placed parallel to the axis of the ski, so that from a certain angle of rotation, the end 10a of the rod tends to escape from the cavity 12 and slides on the side of the plate 1. The tension is however maintained, or even increased by a stop 13 located below the axis 9b. In this position, the elastic energy accumulated in the stop element is maximum.
  • the heel piece 3 When the torsional safety binding is triggered, the heel piece 3 is rotated by the shoe 5. Since the pedal 7 is mounted on the heel piece 3, it follows the shoe in its movement by reducing the relative displacement between the shoe and the pedal, keeping the resistance due to friction to a minimum value. The pedal 7 slides on the part 9c of the stop elements. If pedal 7 is made of plastic and the rods 9 of metal, the friction of the pedal 7 on the rods 9 can be perfectly controlled and kept at a very low value. This is all the more advantageous when the sole of the shoe is degraded.
  • the binding constitutes a completely equipped assembly independently of the ski, which facilitates the mounting of the binding on the ski.
  • FIG 3 shows a binding consisting of a heel piece 14 and an independent front stop 15.
  • the heel piece 14 is fixed in rotation and opens upwards, while the stop 15 can pivot.
  • the stop elements 6 are mounted on an independent part 16 fixed on the ski in front of the heel piece 14.
  • the pedal 7 is articulated on the heel piece 14.
  • FIG. 4 represents a plate attachment of the same type as that shown in FIG. 1.
  • the stop elements are mounted on a piece 17 independent of the plate 1 and fixed on the ski 2.
  • the pedal 7 it is articulated on the plate 1. In this case also the pedal 7 accompanies the shoe in its rotational movement when triggering the torsional attachment.
  • the part 17 could be part of the plate.
  • FIG. 5 schematically represents the same binding as that shown in FIG. 3, but in which the part 16 carrying the stop elements 6 is fixed on the ski 2 slightly behind the pivoting stop 15.
  • the pedal 7 is fixed on the support of the front stop 15.
  • FIG. 6 schematically represents an attachment to a sub-foot plate 18 comprising a heel piece 19, pivoting or not, and a front stop 20 pivotally mounted on the plate 18.
  • the stop elements 6 are articulated on the plate 18 , as in the first embodiment, while the pedal 7 is mounted on the pivoting front stop 20.
  • This assembly has the same advantages as that of FIGS. 1 and 2.
  • Figure 7 shows a binding similar to the binding shown in Figure 3. It differs in that the stop elements 6 are articulated on the heel 14, so that it can be delivered fully equipped with the device d 'stop.
  • the stop element shown in Figures 1 and 2 is of course only an example of execution. It could be replaced by any other embodiment such as an element consisting of a single elastic metal rod in the form of a hairpin or a device comprising an auxiliary spring. In some cases we could have only one stop element.
  • the pedal is mounted on the binding, while the stop elements are articulated obliquely directly on the ski, the part 9b penetrating into a vertical side of the ski and coming out on the upper face of the ski. .
