Definitions

  • the present invention relates to a ski brake comprising two movable braking arms, intended to be arranged on either side of a ski, and the active ends of which are retracted above the ski in their raised position, while their opposite ends are joined by a control pedal capable of being actuated by the corresponding shoe of the skier, the braking arms being exclusively carried by the control pedal which is articulated on the ski around a transverse axis.
  • the invention relates to ski brakes of this kind, the arrangement of which is such that the active ends of the two movable braking arms are retracted above the ski when these are raised in the retracted position.
  • ski brakes thus designed so as to prevent the active ends of the braking arms from overhanging with respect to the side edges of the ski in their lifting position.
  • FIG. 7 of French patent FR-A-2 055 424 describes a ski brake in which the brake arms are retracted into the retracted position thanks to a pivoting around a longitudinal axis.
  • French patent application FR-A-2 447 208 also describes a brake, the braking arms of which are retracted in the retracted position. This retraction is obtained by a pivoting movement of the braking arms ensuring a raising of their active ends above the ski.
  • this has the drawback of involving a large size of this brake in the height direction.
  • French patent applications FR-A-2451 754 and FR-A-2 452 300 relate to ski brakes in which the retraction of the brake pads is obtained in a way by an oscillating movement of the two corresponding arms in the transverse direction thanks to a movement of these inside the bearings in which their bent parts are articulated serving as pivot axes. This oscillation movement is then controlled by the relative pivoting which occurs between the control pedal and the corresponding ends of the brake arms at the end of the lifting movement of the latter.
  • the present invention aims to achieve a ski brake of the same general type, but which is designed so as to avoid the drawbacks mentioned above.
  • the design of this brake is therefore such that it is particularly simple and inexpensive.
  • This design is also such that the retraction of this brake can be carried out without significant efforts and that it is possible to provide a return spring of limited power.
  • the opposite ends of the braking arms of the ski brake according to the invention are bent to form a V having its point directed on the side opposite the active ends of these arms and / or on the side opposite to the ski and are mounted swiveling in bores, of the same angular orientation, formed in the pedal, however means are provided which cause the braking arms to rotate on themselves in these bores, after their raising, so that their active ends are thus retracted to the above the ski in the standby position of this brake.
  • the means provided for controlling the rotation of the braking arms on themselves in their retracted position are constituted by elastic members constantly tending to cause such rotation, ci being prevented from occurring until the braking arms have not been raised above the upper surface of the ski.
  • the rotation of the braking arms in their retracted position is caused by a stop disposed above the position for raising the active ends of these arms.
  • this stop prevents these ends from continuing their lifting movement when the control pedal is folded against the ski, which forces the braking arms to turn on themselves in the bores provided inside this pedal.
  • the stop thus provided may be constituted by another element of the corresponding ski equipment, for example by the rotary plate of a pivoting heel piece for fixing.
  • the ski brake shown in FIGS. 1 to 7 comprises two movable arms 1, made of rigid metal wire, which are intended to be arranged on one and the other sides of the corresponding ski S. Contrary to what is the case in the most ski brakes of this kind, these two arms do not articulate directly on the ski. In fact, they are exclusively carried by a control pedal 2 capable of being actuated by the corresponding shoe of the skier. This pedal is articulated around an axis 3 which extends in the transverse direction above the ski and parallel to the upper surface thereof, this axis being carried by a plate 4 fixed on the top of the ski.
  • the two brake arms 1 are mounted on the control pedal 2 via one of their ends, in this case their end 5 which is opposite to the active end 6 on which a brake shoe is provided. 7.
  • the ends 5 of the two brake arms 1 are bent towards one another and mounted to rotate on themselves inside bores 8 formed in the thickness of the control pedal 2 and which have the same orientation angular. These ends are retained in place by a pin 9, or any other suitable member, allowing them to rotate on themselves.
  • the plane formed by the bent ends 5 of the two braking arms is parallel to the upper and lower faces of the pedal 2. Given their inclination relative to each other, the bent ends 5 of the two braking arms 1 form a V whose apex 0 is directed on the side opposite the active ends 6 of these two arms (see FIG. 7). Of course this summit is also located in the plane perpendicular to the ski which passes through the median longitudinal axis XY thereof.
  • the bending angle has braking arms and the angular orientation of the bores 8 provided in the thickness of the pedal 2 are such that the spacing of the ends of the braking pads can be modified, by simple rotation of the arms 1 on themselves inside the bores 8, between a maximum spacing L1, corresponding to the working position of these two arms and a minimum spacing position L2 corresponding to the lifting position of these above the ski, when the brake is awaiting operation.
  • This minimum spacing L2 is such that the braking arms, and in particular their ends 6, are retracted tees with respect to the lateral sides of the ski so as not to project beyond them (see FIG. 7).
  • elastic return members which tend to rotate on themselves, the bent ends 5 of the braking arms inside the bores 8, in their position corresponding to the minimum spacing L2 of the active ends of these same arms.
  • These elastic members may consist of cylindrical rubber pads 10, housed in the thickness of the pedal 2, and each acting against a flat 11 provided on the bent end 5 of the corresponding braking arm.
  • the angular orientation of this flat is such that it is disposed tangentially to a generator of the corresponding elastic buffer 10 when the respective braking arm 1 is in its retracted position (see FIG. 4).
  • the flat 11 may include the position shown in FIG. 4a. In this case the elasticity of the elastic pad tends to return the corresponding arm to its retracted position.
  • This spring is provided to raise the control pedal 2 in the position shown in FIGS. 1. 3 and 5.
  • This spring may consist of a torsion spring 12 placed around the articulation axis. 3 of this pedal.
  • the spring 3 causes the lifting of this pedal and the brake pads 7 are thus brought to bear on the ski.
  • This causes the braking arms to rotate on themselves inside the bearings 8 provided in the pedal 2, until their braking pads have sufficient spacing for these arms to pass on either side. lateral sides of the ski.
  • the brake pads 7 are automatically brought into their maximum spacing position L1, which is their working position.
  • the spacing and approximation movements of the braking arms are due to the bent shape of their control ends 5 and to the angular orientation of the bores 8, formed inside the pedal 2, to serve as rotational bearings at the corresponding ends of these two arms.
  • these movements are carried out without significant friction of the braking arms against the ski or against ancillary parts fixed on it. Therefore, a return spring 12 of relatively low power is sufficient to control the movement of these arms in their active working position.
  • the boot in the waiting position, the boot is not made to undergo a significant vertical thrust liable to disturb the triggering of the safety binding ensuring the retention of this boot on the ski.
  • Yet another advantage of the brake according to the invention consists in that it has an extremely small size in the height direction. This allows it to be arranged without disadvantage below the location of the central part of the corresponding shoe.
  • Figures 8 to 10 show a variant of the embodiment described above. It differs therefrom only in that the resilient members for returning the braking arms in their retracted position, are assumed 'winning and the corresponding movement is then controlled by a stop arranged above the lifting position of the brake pads.
  • this stop may advantageously be constituted by another element of equipment of the corresponding ski, in this case the turntable 13 of a fixing heel piece 14.
  • FIGS. 11 to 13 show another embodiment of the ski brake according to the invention. This differs from that shown in FIGS. 1 to 7 by a different orientation of the bores made in the thickness of the control pedal and which serve as rotation bearings at the corresponding bent ends of the braking arms.
  • the plane formed by the bent ends 5b of the braking arms 1b, is perpendicular to the upper and lower faces of the control pedal 2b. Furthermore, the top 0 of the V, formed by the axes of these two bent ends, is directed upwards, and no longer on the side opposite to the brake pads (see FIG. 12).
  • the arrangement is such that in the raising position of the braking arms 1b, corresponding to the folding of the control pedal 2b against the ski, the braking pads 7b have a minimum spacing whereby they are then retracted from on the lateral sides of the ski (see figure 11). But due to the angular orientation of the bores 8b, provided in the thickness of the pedal 2b, and due to the elbow of the braking arms 1b, the raising of the control pedal is accompanied by a spacing of the pads braking 7b on either side of the ski by rotation of these arms in the corresponding bores.
  • the return of the braking arms to their retraction position, shown in FIG. 11, can be ensured either by elastic members, such as the cylindrical buffers 10 provided in the embodiment of FIGS. 1 to 7 , or by a stop limiting the raising of the brake shoes, as provided in the variant according to FIGS. 8 to 10.
  • the brake according to the invention is not limited to the examples which have been described above for information only.
  • the plane formed by the bent ends of the braking arms could be inclined relative to the upper and lower faces of the control pedal instead of being parallel or perpendicular to it, the top of the V formed by the axes of these ends would then be directed both on the side opposite to the brake pads and upwards, that is to say on the side opposite to the ski.
