Definitions

  • the present invention relates to ski brakes comprising two braking arms, arranged on either side of the ski, and which are subjected to the action of a spring tending to return them to their active position.
  • each braking arm may advantageously consist of a metal wire suitably bent to form a lower section carrying a brake shoe, an intermediate section pivotally mounted on the ski and an upper section subjected to the shoe pressure when it is in place.
  • the invention relates to a ski brake comprising two braking arms arranged symmetrically on either side of the lateral sides of the ski and each of which is bent to present a lower section carrying at its lower end a brake shoe , a . intermediate section pivotally mounted with a certain clearance in a transverse bearing fixed on the ski and an upper section subjected to the pressure of a boot when the latter is in place on the ski, the pivoting of the lower section into the upper plane of the ski, followed by its erasure inwardly in this plane above the ski is produced by folding the upper section by the boot towards said plane followed by a portion of this upper section, the return of the braking arms in their active position being ensured by a helical spring attached to the top of the ski.
  • the ski brake according to French patent FR-A-2 452 300 implements a caliper or a central control pedal, the ends of which are fixed on sleeves mounted to rotate around the corresponding ends of the pivoting arms. , these being articulated in the center around a common axis.
  • a caliper or a central control pedal the ends of which are fixed on sleeves mounted to rotate around the corresponding ends of the pivoting arms. , these being articulated in the center around a common axis.
  • such an embodiment if it makes it possible to obtain a retraction of the brake pads in the retracted position so that they do not overflow on the sides of the ski, presents for its practical realization certain difficulties due in particular to the use of an axis of articulation between the two upper sections of the arms.
  • the present invention relates to a ski brake which brings to a general arrangement of the kind mentioned above improvements which are particularly useful because of the constraints and severe conditions of use of such a ski brake.
  • the provisions of the invention make it possible to control the pivoting and the retraction of the lateral arms of the brake with less effort, the action being exerted on them in two distinct places in a median position along the length of these arms.
  • each branch of the brake being produced independently in two distinct sections, the recommended arrangements make it possible to ensure a significant reduction in the force to be exerted on the arms.
  • the ski brake in question is characterized in that each upper section of a braking arm carries at its upper end a pivoting lateral control flap, the two flaps being connected by a median and continuous upper arch, in this that each upper section extends in a direction substantially opposite to that of the lower sections and in that its upper end ends in the corresponding pivoting side flap, the two flaps extending each upper section, and in that each of these flaps has two blind and opposite bores receiving respectively on the side of each arm the upper end of the upper section and the lower end of the arch, these bores forming an angle with respect to each other and serving as an articulation bearing respectively for the upper section and the arch, the angle of the axes of the bores of the same flap being such that the flat folding of the flap against the ski by pivoting automatically Our branch of the upper arch causes the corresponding brake shoe to move towards the median axis of the ski and the helical spring being a tension spring attached directly to the upper arch.
  • This ski brake comprises two braking arms 1 systematically arranged with respect to the median longitudinal plane of the ski S. Each of these arms is bent in a plane so as to have a lower section 2 carrying a braking pad 3, an intermediate section 4 pivotally mounted in a bearing 5, and an upper control section 6.
  • the two bearings 5 are carried by a plate 7 serving as a base for mounting the assembly on the ski S by means of screws 8.
  • These two bearings are arranged so as to somehow materialize a transverse axis XY for pivoting of the two braking arms 1.
  • the intermediate sections 4 of these have a certain clearance inside these bearings.
  • each braking arm carries a pivoting control flap 9 and the two flaps thus provided are connected by an upper arch 10, made of metal wire, as are the braking arms 1.
  • Each of the flaps 9 has two separate bores 11 and 12 serving as articulation bearings, respectively at the end of the upper section of the corresponding arm and at the respective branch of the connecting arch 10.
  • the axes of these bores do not are not in line with each other or parallel. Indeed, they form an angle between them such that the flat folding of the two flaps 9 against the ski, by pivoting around the branch of the upper link arch 10, determines a bringing together of the brake pads 3 by movement of the intermediate sections 4 of the arms 1 inside the bearings 5.
  • a rod 15 Inside this spring is arranged a rod 15 whose length is such that it serves as a stop limiting the deployment of the pivoting arms in the desired position for braking.
  • the brake pads are arranged on either side of the edges of the ski as shown in Figures 1 and 2.
  • the two control flaps 9 they are then slightly raised outwards.
  • each of these components has the effect of exerting an inward traction on the corresponding braking arm. This therefore causes the brake pads to retract into the position shown in FIG. 4, the position for which these pads are set back relative to the edges of the ski.
  • the main advantage of the ski brake according to the invention lies in the simplicity and efficiency of the means provided for ensuring the retraction of the brake pads in their retracted position.
  • this retraction requires less effort than in the case where it is obtained by folding down a single control pedal pivoting about an axis. transverse.
  • this retraction is obtained by the folding of the two flaps 9 pivoting around two axes extending in a longitudinal direction. This folding down therefore requires less effort and the forces exerted are much better distributed than in the case of pressing on a single pedal.
  • this facilitates the installation of the boot in the binding of the corresponding ski, because the final folding of the two control flaps is easier to achieve.
