Definitions

  • the present invention relates to a ski brake which comprises two brake arms pivotally mounted in bearings arranged transversely from top to bottom when moving from the outside towards the inside of the ski. These arms are connected to each other by an elastic hoop which is located above the ski and is capable of deforming elastically in bending in its own plane.
  • This type of brake has the advantage that, when the arms are in the inactive position, they do not protrude, or protrude slightly, outwards on the sides of the ski.
  • control spring is constituted by an elastic wire hoop working on bending, the ends of which are each attached to a braking arm.
  • This hoop plays both the roles of control spring and of operating pedal.
  • This type of brake which is described in patent FR-A No 2441397 (FIGS. 5 to 8), is particularly advantageous because of its simplicity and its low cost price.
  • the invention makes it possible to solve this problem in a particularly simple and effective manner by connecting the hoop to the braking arms by means of articulations whose axes are perpendicular to the plane of the hoop. Thanks to this arrangement, the bending stresses are evenly distributed in the arch, the ends of the latter being articulated and no longer embedded.
  • the hoop advantageously has the shape of a C or a U depending on whether the joints are located inside or outside the ski with respect to the bearings.
  • the arch can be made of spring steel wire or molded plastic.
  • the brake shown in FIGS. 1 to 4 comprises a base plate 1 which is fixed to the ski S by suitable means such as screws 2.
  • the plate 1 is provided with a pair of bearings 3 whose bores have X, Y axes which are arranged in a vertical plane transverse to the ski S, but inclined up and down when moving from the outside towards the inside of the ski.
  • a metal wire brake arm 4 which, in a well known manner, carries a brake shoe 5 made of overmolded plastic.
  • the arms 4 are extended on the inner side to the bearings 3 by bent sections 6.
  • the brake control spring consists of an elastic hoop 7 fixed at its ends to the sections 5.
  • the hoop 7 is made of steel wire with spring and has the shape of a C. According to the invention, the hoop 7 is fixed to the sections 6 by means of joints whose axes Z are perpendicular to the plane of the hoop.
  • This ski brake operates in the following manner: when putting on his ski, the skier applies his shoe against the hoop 7, which therefore serves as a maneuvering pedal.
  • the hoop 7 comes to lie flat on the ski while the skids 5 are raised as they approach the center of the ski, due to the inclined position of the axes X, Y (fig. 4).
  • the sections 6 deviate from one another towards the outside of the ski by deforming the arch 7 in the direction of its opening (arrows F, fig. 4). Thanks to the joints 8, the arch 7 deforms in a natural and regular manner, a slight angular displacement occurring between the end of its branches and the sections 6.
  • the boot stops pressing on the arch 7 which deforms to regain its initial shape. This deformation brings the hinges 8 closer to each other, causing the arms to tilt to their active braking position.
  • the brake of fig. 5 differs from that which has just been described only by the fact that the elastic hoop 17 is made of plastic.
  • the shape and thickness of this arch is preferably designed such that the bending stress is the same over the entire periphery of the arch.
  • the arch 17 is obtained by molding a thermoplastic resin such as an acetal resin, for example.
  • Fig. 5A shows the articulated connection mode of the arch 17 with the arm sections 6: each end of the arch 17 is shaped as a yoke comprising cheeks 17a between which is housed the flattened end 6a of the associated section 6, a rivet 8 ensuring its fixing.
  • the brake of fig. 6 differs from the previous ones by the fact that the articulations 8 of the arch 27 on the arms 4 are located outside the ski with respect to the bearings 3 and below the axes X, Y.
  • the sections 20 of the arms 4 which are arranged in the bearings 3 each carry an end flange 21 preventing them from coming out of the bearings 3 under the force exerted by the elastic arch 27.
  • the arch 27 is made of U-shaped spring steel wire. During the raising of the arms to their inactive position, the articulations 8 approach each other, so that the arch is deformed this time in the direction of its closure. Conversely, when the boot leaves the ski, the arch 27 opens to resume its initial shape, causing the arms 4 to pivot towards their active braking position.
  • the brake shown in figs. 7 and 8 is identical to that of FIGS. 1 to 4, with the difference that it is fitted with an added raising pallet 30.
  • This pallet made of molded plastic material, for example polyamide, comprises a flat back face 31, the upper edge 32 of which is rounded .
  • the pallet On its ventral surface 33, the pallet has a semi-cylindrical transverse groove 34 and a central stop 35 provided with two lateral grooves 36.
  • the pallet 30 is fixed to the brake pedal by elastic snap-fastening, on the one hand, of the portion transverse of the arch 7 in the groove 34 and, on the other hand, bent sections 6 of the arms 4 in the grooves 36.
  • the base plate 1 is provided, on its upper face, with a boss 10 against which comes resting on the lower part 37 of the pallet 30.
