Definitions

  • the present invention relates to a ski brake of the kind comprising two pivoting arms, both articulated around a horizontal axis transverse to the ski.
  • the arms also have the possibility of movement in the plane of the ski.
  • An elastic return member constantly biases the arms in the active position in which the braking ends protrude below the plane of the sole of the ski and have a maximum mutual spacing.
  • the braking ends are raised above the plane of the ski and then tilt parallel to it to get closer to each other.
  • the braking ends are then in the retracted position above the ski and do not project laterally on the sides of the ski. This is an advantage for the skier, the braking ends not being exposed to the risk of catching on possible obstacles, such as roots, which may be on the track.
  • the elastic return member causes the brake to be redeployed, the braking ends of which start by moving away from one another to cross the edges of the ski, then pivot down to crash. in the snow.
  • a relatively simple ski brake of the type described in which a naturally curved elastic blade, forming a pedal, connects the control ends of the arms opposite their braking ends to one another.
  • the curved elastic blade tends to bring the control ends closer to one another and therefore to separate the braking ends from each other.
  • This embodiment has the drawback consisting in the fact that, the leaf of the spring being crushed by the shoe, exerts under the sole thereof a high pressure which constitutes a parasitic stress which can disturb the normal operation of the safety binding.
  • the use of a relatively strong blade being necessary to obtain effective braking, this parasitic constraint can reach an excessive and dangerous level.
  • the invention aims to remedy this drawback by providing a ski brake in which no parasitic stress is likely to interfere with the normal operation of the binding when the boot is in place on the ski and the brake in the retracted position at above it.
  • FIG. 1 to 3 there is shown a first embodiment of the ski brake according to the invention, which comprises two braking arms 1 each constituted by a suitably shaped metal wire.
  • Each arm 1 has a bent part 2 articulated in a bearing 3 around a horizontal axis xx and transverse to the ski S.
  • the bearings 3 are carried by a plate 4 fixed to the ski S by suitable means not shown such as screws.
  • the shape of the bearings 3 allows a certain angular movement of the bent parts 2 relative to the transverse axis xx.
  • Each of the arms 1 consists, in a well known manner, of a control end 6 and of a braking end 7 provided with an overmolded pad 8.
  • Each control end 6 has a transverse end portion on which is rotatably mounted a cylindrical ring 15.
  • the blade 14 passes through an operating pedal 5 with which it is secured in its central region.
  • An elastic return member, in the form of a traction member, is articulated by one of its ends to lugs 12 carried by the plate 4 and by its other end to the operating pedal 5.
  • l 'traction member comprises a cylindrical tube 11, a tie rod 13 provided with a head 13a which can slide in the tube 11, and a compression spring 9 disposed between the head 13a and the bottom of the tube.
  • This embodiment has the advantage of being particularly robust and waterproof; however, it would be possible to provide a traction member of a different type, for example, a simple traction spring.
  • the blade 14 gradually presents at the line of action of the spring 9 no longer its face, but its edge; the spring 9 therefore acts on a blade 14 whose moment of inertia increases so that at the end of the stroke it can no longer ensure its flexion.
  • the blade which was curved therefore takes on a planar configuration, and therefore its ends separate the rings 15, the axes of which take a transverse direction, from one another.
  • the sections 2 tilt in the bearings 3 and the braking ends 7 (and their shoes 8) approach each other to come to occupy a retracted position above the ski (see Figure 3).
  • the spring 9 recalls, by means of the traction rod 13, the pedal 5 and the blade 14 which gradually tilt, the rings 15 swiveling on the end portions of the control arms 6 ends 1
  • This movement is obtained by virtue of the fact that the tie rod 13 is hooked under the pedal 5, eccentrically with respect to the axis of the rings 15.
  • the blade again having its main face to the axis of traction of the rod 13 , the blade 14 curves, and the pads 8 move away from one another by crossing the edges of the ski (FIG. 2).
  • the traction member 13 causes the raising of the control ends 6 of the arms 1, the latter pivoting about the transverse axis xx while the pads 8 come to be placed in the braking position, projecting below the plane of the ski sole ( Figure 1).
  • the ends 14a of the blade 14 are engaged and guided in openings formed in the sides 16 of the operating pedal 17, the rotation of which by the shoe consequently entails the pivoting of the blade 14 on itself.
  • the ends 14a pass through sleeves 18 similar to the sleeves 15 of the previous embodiment, and which rotate on the control ends 19 of the arms 21.
  • the traction rod 13 is articulated on a transverse axis 20, integral with a stirrup 22 crossed by the central zone of the elastic blade 14.
  • the blade 14 is embedded by its central region in a median extension 23 of the operating pedal 24. Furthermore, its ends are engaged in rings 18 journalling on the ends of control 19 of the arms 21, as in the embodiment of FIGS. 4 to 6.
  • the traction rod 13 of the return spring 9 is articulated on a transverse axis 25 mounted in the extension 23.
  • the blade 14 In the active braking position, the blade 14 has the curved shape visible in FIG. 7, under the effect of the restoring force exerted by the spring 9 on the pedal 24 by the extension 23 thereof.
  • the intermediate bent parts of the pivoting arms 21 are in abutment inside the associated fixed bearings 3, the arms 21 being in the position illustrated in FIG. 7.
