Definitions

  • the present invention relates to a braking device for fixing a gliding board such as a ski.
  • the invention is more particularly intended for the practice of ski touring.
  • Ski touring has two distinct phases.
  • the “descent” phase the “climb” phase.
  • the boot is held on the ski by the binding means without possible movement relative to each other.
  • This phase is similar to the practice of downhill alpine skiing.
  • the boot can be separated from the ski either following a voluntary action by the user or during a fall. In both cases, the braking device must be able to deploy.
  • braking devices include a support pedal energized by a spring which controls the deployment of the brake: When the shoe is in place in the binding, the pedal is constrained by the shoe and the brake is retracted so as not to not hinder gliding. As soon as the shoe is no longer in place, the stress on the pedal is released and the brake is deployed. In the second phase, “the ascent phase", the braking device must be inhibited so that the brake remains permanently retracted, even when the skier lifts the heel of his boot.
  • This braking device is also not satisfactory for use in ski mountaineering.
  • This competitive practice requires efficient, reliable, optimized and especially as light as possible. Under these conditions having a braking device entirely independent of the shoe retaining means is disadvantageous.
  • the aim of the invention is to propose an improved braking device.
  • the lever in the unlocking position the lever is substantially horizontal and the pedal is able to pivot around the fourth axis of rotation while in the locking position, the lever stands up relative to the base and the pedal is immobilized.
  • the braking device 1 comprises a braking element 11.
  • This braking element shown alone in the Figure 3 , consists of a folded metal wire with a diameter of between 1 and 5 mm, preferably between 1.5 and 3.5 mm.
  • the braking element has symmetry with respect to the longitudinal axis figure 1 and to the Figure 2 .
  • the braking element 11 and the base 10 are arranged relative to the ski so that the spades are spaced from the side edge of the ski.
  • the braking branch rotates around its axis Y111, in a first direction S1
  • the spades 112a, 112b tilt so that their free end protrudes from the sole of the ski, downwards, to grip the snow.
  • This configuration of the braking device is referred to as the braking configuration.
  • the free ends can be fitted with end caps (not shown).
  • the spades 112a, 112b return to a recessed position, upwards, relative to the sole ski.
  • this configuration of the braking device called gliding configuration
  • no part of the braking branch projects from the sole of the ski.
  • the braking device does not obstruct the movement of the ski.
  • the rotation of the braking element is controlled by the pedal 12, which cooperates with the activation portion 114 of the braking element.
  • the pedal 12 extends in a longitudinal direction between a base 124 and a rear end 125. It comprises a guide housing 122 which is crossed by the activation portion 114 of the braking element 11.
  • This guide housing 122 is in the form of an oblong cavity extending in the longitudinal direction of the pedal.
  • the height of the guide housing is slightly greater than the diameter of the activation portion and the latter can slide longitudinally inside the guide housing.
  • the position of the activation portion inside the guide housing is constrained towards the rear end 125 of the pedal by an elastic means 13.
  • the elastic means consists of a spring 131 and a piston 132 which serves as an interface between the spring and the activation portion 114.
  • the braking device further comprises a lever 15 which is pivotally mounted on the base 10.
  • the lever 15 has a general U shape with two branches 151a, 151b extending substantially longitudinally and connected to each other by their front end by a gripping bar 152.
  • the rear end of each of the branches 151a, 151b is fixed to the base 10 via a shaft 103 in order to constitute the pivot connection between the lever 15 and the base 10.
  • Lever 15 pivots around the second axis of rotation Y15 between two extreme positions. The first of these positions is called the position of unlocking. It is illustrated in figures 1, 2 , 4 , 7 and 8 .
  • the second, called the locking position is illustrated in figures 5, 6 And 9 .
  • the pedal 12 and the lever 15 are two separate parts, but they are connected to each other so as to allow relative rotational movement.
  • This connection is made at the base 124 of the pedal 12 which is fixed to the front ends of the branches 151a, 151b near the gripping bar 152.
  • This is a pivot connection which allows the pedal to rotate around the fourth axis Y12 which is perpendicular to the longitudinal axis X and parallel to the axes Y111, Y114 and Y15. In the chosen embodiment this pivot connection is made with a shaft 126 visible at the Figure 6 .
  • the braking device can be placed in two configurations: the “gliding” configuration and the “braking” configuration.
  • the device in the “glide” configuration is visible at the figure 4 and schematically at figure 8 .
  • a ski boot is retained by the binding device.
  • the rear part of its sole 4 represented in figure 4 by a dotted line, rests on the pedal and forces it to pivot around the axis Y12 until the rear part of the pedal is as close as possible to the upper surface of the ski.
  • the lever 15 and the base 10 have recesses which allow the pedal 12 to retract almost entirely between the two branches of the lever as can be seen in the figure 4 .
  • the braking device is in the “braking” configuration, as shown in Figure figure 1 , to the figure 2 and schematically at Figure 7 .
  • the spades 112a, 112b are projected under the ski/snow contact plane 21 and are able to grip the snow and hinder gliding.
  • the angle ⁇ 12 that the pedal 12 makes with respect to the lever 15 is at its maximum, it is between 10° and 60°.
  • the pedal in the locked position, is reversed, that is to say that its rear end 125 is placed further forward than its base 124.
  • the rear end of the pedal is the place where there is the axis Y114 which ensures the pivot of the activation portion 114 of the braking element, this makes it possible to make the tilting of the latter irreversible.
  • the schematic figures of the Figure 7 and some Figure 9 demonstrate the kinematics of the braking device according to the invention.
  • the two axes Y111 - pivot of the braking element 11 relative to the base - and Y15 - pivot of the lever 15 relative to the base - are fixed because linked to the base 10, itself fixed on the ski.
  • the axis of the lever, also called the third axis Y15, is placed forward in relation to the first axis Y111. This relative position of axes Y15 and Y111 is preserved in all operating phases.
  • the fourth axis Y12 - pivot of the pedal 12 relative to the lever 15 - and the second axis Y114 - pivoting and sliding connection between the braking element 11 and the pedal 12 - have positions which change in the different phases and/or configurations .
  • the braking element 11 In the descent phase, as long as the shoe 4 exerts pressure on the rear end of the pedal at the level of the axis Y114, the braking element 11 is forced to rotate in the direction S2 and its ends remain at the above the ski/snow contact plane 21. This is the “slide” configuration, illustrated in figure 8 .
  • a second embodiment is described in Figure 10 and to the Figure 11 .
  • the braking device 1 does not present any essential differences with the device of the first embodiment of the invention.
  • the gripping bar 152 of the lever rests directly on the rear portion of the base 10.
  • the lever always rests in an almost horizontal position, whether in the locking position or in the unlocked position.
  • the operation of the braking device is completely independent of the heel piece 3. This has the advantage of being able to mount this braking device with any heel piece.
  • the characteristics of the kinematics of the first embodiment are still present in this embodiment. Indeed, during the descent phase ( fig.
  • the fourth axis - pivot of the lever relative to the pedal - is positioned in front of the third axis - pivot of the lever relative to the base.
  • the fourth axis finds itself positioned behind the third axis.
  • the third axis is placed on the base in front of the first axis - pivot of the braking element relative to the latter.
  • this construction can also allow the spades to retract when the braking element is in the sliding configuration, as well as during the ascent phase. We speak of spade retraction, to describe a movement of the spades directed towards the longitudinal axis and which therefore prevents them from protruding in the transverse direction.
