Definitions

  • This invention relates to a method at the release of ski bindings, and to a ski binding intended to bring about this release method.
  • Ski bindings and especially slalom bindings, must be constructed so that they release when the ski boot is loaded in certain directions by predetermined forces.
  • Such forces, at which the ski binding is to release, can be adjusted optionally.
  • the aim is that the force for releasing the binding is sufficiently great for rendering normal use of the ski possible, but sufficiently small for preventing at accidents legs and feet to be injured.
  • the adjusting of the ski binding is carried out by a specialist, and the principle is to adjust a spring tension. Even when a correct adjustment of the binding can be obtained,optimum adjustment is not achievable due to the fact, that the binding can be affected by forces having varying directions.
  • An adjustment which is correct for preventing leg fracture at fall forward, does not imply automatically that the binding is adjusted correctly when, for example, the foot is twisted in the binding. Very often the skier himself adjusts the release force of the binding.
  • mechanical bindings also have been combined with sensing members arranged in the ski boot and intended by action of a predetermined force to release the binding.
  • leg fractures use to occur at slalom skiing. These fractures, besides, normally are very complicated.
  • the present invention relates to a ski binding, which acts according to an entirely new way of thinking, as stated in the characterizing clauses of the claims.
  • a release of the binding is obtained, i.e. the ski loosens from the boot instantly as soon as an unnormal pressure arises between the boot and foot and/or leg in the boot.
  • the invention operates with a purely magnetic binding between boot and ski. This binding is broken instantly on order from pressure-sensitive cells, which are located in selected places on the inner surface of the boot. Forces not injurious per se when acting alone can, when combined, give rise to leg fracture. According to the invention, this is excluded because the pressure-sensitive cells in different areas of the boot are combined with each other and release the binding even when the individual forces each alone would not open the binding.
  • Fig. 1 is a lateral section of one embodiment of the invention
  • Fig. 2 is a corresponding section through a second embodiment of the invention
  • Fig. 3 shows boot and ski dashed and schematically with inserted coils according to the latter embodiment.
  • 1 designates a boot
  • 2 designates the ski.
  • an electromagnet 4 is cast, the lower surface of which lies in the plane of the sole surface.
  • the plate 3 is provided with a pair of elevations in the form of cone-shaped warts 5, which engage with corresponding recesses in the sole of the boot.
  • the inner surface of the boot 1 is provided with pressure-sensitive cells, which are marked in the form of spots 6 and distributed uniformly on the boot inner surface.
  • the cells may, for example, be in the form of piezoelectric elements, which upon load emit a current pulse. From a suitable current source (not shown) the electromagnet 4 is supplied with current, which via a suitable connection with amplifier can be broken by the current impulse or signal from the cell 6.
  • the electromagnet 4 consists of two metal bars 7, which are cast into the sole of the boot in parallel with each other. Each bar is provided with five downward directed cylindric metal cylinders 8,which form cores for coils 9.
  • the coils are wound of 500 windings and connected in series, supplied by a 9 V, 1,0 A battery, which, for example, can be stored in a pocket in the boot (not shown) or in another suitable place.
  • the current to the coils 9 is broken in the way described above at disadvantageous load on the foot and/or leg.
  • the boot 1 is guided in lateral direction on the ski by means of low studs 10 attached in suitable arrangement on the ski. These studs have no binding effect per se between ski and boot.
  • a current source suitable for the purpose can be used which is carried, by the skier and built-in in the boot, or attached to the ski. In the latter case electric connection to the boot must be provided.
  • electric connection to the boot must be provided.
  • studs 5 according to Pig. 1 instead of studs 5 according to Pig. 1, of course, also edge guides for the boot can be used.

Abstract

Cette invention concerne la liberation d'une fixation de ski. La chaussure est pourvue sur la surface interne de cellules sensibles a la pression (6) qui sont actionnees par des charges predeterminees exercees par le pied et/ou la jambe. Au moins un electro-aimant (4; 8) est prevu dans la chaussure et alimente en courant, lequel peut etre interrompu par des signaux provenant des cellules sensibles a la pression (6) dans le cas ou elles sont chargees, et au moins un induit (3) attire par l'electro-aimant est concu de maniere telle que, lors d'une interruption du courant, la liaison de l'induit sur l'electro-aimant cesse, et la chaussure (1) se degage du ski (2).
