Definitions

  • ABSTRACT A ski brake for slowing down and stopping the movement of a ski on a slope when the ski boot slips out of the ski binding.
  • the ski brake preferably comprises a U-shaped member having a transverse portion located, during use of the ski, between the top face of the ski and the front end of the sole of the ski boot and a pair of legs extending closely adjacent to opposite side faces of the ski forwardly of the transverse portion, and a leaf spring attached at opposite ends to the transverse portion and the top face of the ski and biased to tilt the U-shaped member, when the boot slips out of the ski binding, to a position in which the U shaped member includes an angle with said top face and the legs will dig into the snow beneath the bottom face of the ski.
  • the present invention relates to a ski brakefor slow- 1. ing down and stopping the movement of aski on aslope when the skiboot slips out of the ski binding.
  • the ski brake according to the present invention forslowing down and stopping the movement of a ski on a. slope when, during skiing, the boot of the skier slips out of the ski binding, mainly comprising a mobilecmember having a portion extending transverse to the top face of the ski and at least one elongated prongintegral at one end with said transverse portion and located laterally of a side face ofthe ski, in which the mobile member is located, when the boot of the skier is held by the ski bind-.
  • the skibrake includes two prongs which project forwardly'from the transverse portion of the mobile memb'en and which are located closely adjacent sand'parallel tothe side faces of the ski.
  • FIGJ3 isa partial cross section similarto FIG. 2, but showing the-ski brake in an active position it will assume'when theski boot has slipped out ofthe ski bindmg.
  • FIG. 1 illustrates aski brakewaccordingto the present inventionibeforeitisattached: to a'ski.
  • the ski brake preferably comprises a substantially U-shaped member having a transverse portion 3 *an d a pairof prongs or legs 4'projecting forwardly from. the transverse portion.
  • The. brake includes furtherbiasing means, which are 5 5 preferably in form of a leaf springl' formed from spring steelt-whichis' located with a major portion thereof between; the 'legsf4 ofttheU-shaped member and which is attached atoneend by rivets2 or the like'to the trans verse portion 3.'of the U-shaped-member; whereas the leaf spring .1 is: provided.
  • the legs or prongs 4 have preferably substan-,
  • the transverse portion 3 of the U-shaped member is preferably covered on its upper surface thereof by a thin plate 7 formed from a material having a low coefficient of friction, for instance polytetrafluoroethylene, available on the market under the tradename of Teflon.
  • a material having a low coefficient of friction for instance polytetrafluoroethylene, available on the market under the tradename of Teflon.
  • the ski brake is attached to the ski 8, shown in part in crosssection, by means of screws 13 extending through the slots 6 in such a manner that the vertical plane of symmetry of the brake corresponds to that of the ski.
  • the ski brake is attached to the upper surface of the ski in such a position so that during normal use of the ski the transverse portion 3 of the brake is located between a front portion of the sole of a ski boot 9 and the upper surface of the ski, which will tension the leaf spring 1 by flattening the same until it assumes a planar position parallel to and abutting against the top face of the ski.
  • the ski boot 9 is during use fixedly held between the front unit 10 and the rear unit 11 of a safety ski binding known in the art and not forming part of the present invention which is constructed to release, during a fall of the skier, the ski boot from the ski.
  • the front portion of the sole of the ski will rest on the thin plate 7, whereas the legs 4 will be positioned laterally and closely adjacent and substantially parallel to opposite side face of the ski and substantially at the level of the top face of the ski.
  • the ski brake will not hinder in any way the movement of the skis on the snow 12 even if the skis assume, when the skier makes a sharp turn, a position transversely inclined to the surface of the snow since in this position the grooves 5 formed at the outer faces of the prongs 4 will prevent any braking contact of these prongs with the snow.
  • the elastic biasing means 1 will curve upwardly at the rear end thereof which is attached to the transverse portion 3, the moment the tension applied thereto by the sole of the ski boot is released, which will result in tilting of the U shaped memberto the position shown in FIG. 3 so that the prongs 4 will project downwardly and forwardly relative to the bottom-face of the ski 8. In this position, the prongs will dig into the snow 12 and the movement of the ski in the direction of the arrow f is instantaneously braked and finally stopped due to the reaction imparted by the prongs in the direction indicated by the arrow f onto the snow.
  • the displacement of the ski boot 9 relative to the ski is not at all hampered by the ski brake since the portion of the boot sole engaging the transverse portion of the U-shaped member can easily slide laterally thereon due to the plate 7 mounted on the transverse member and having a low coefficient of friction.
  • the ski brake according to the presentinvention will assure that the ski at such occasion in which the ski boot slips out of the ski binding will n'otrun away on a slope and can be easily recovered while accidents which could be produced by a runaway. ski are positively avoided.
  • ski brake for slowing down and stopping the movement of the ski when, during skiing, the boot slips out of the ski binding
  • said ski brake comprising a mobile member ofplastic material having at low temperatures a high resistance against bending, said member being substantially U-shaped and havng aportion extending transverse to the longitudinal direction of the ski and two elongated prongs each integral at one end with and projecting from said transverse portion towards the front end of the ski and located laterally and closely adjacent to the respective side face of the ski, said mobile member being, when the boot of the skier is held by the ski binding against the top face of the ski, in an inactive position in which said transverse portion is located between a front portion of the sole of the ski boot and the top face of the ski while said elongated prongs extend substantially
