  • two levers are formed on the front end of the bearing body and the transverse wall or the rear end of the bearing body and the washer of the long pin, which generate a tensile force deforming the release spring and therefore pivoting of the housing against the restoring force of this release spring.
  • DE-A-2 907 917 describes a ski binding in which a bearing body is provided, on which the housing of this binding is pivotally mounted about a vertical axis.
  • This ski binding does not have a transverse wall for guiding the tensile member, but a spring-loaded piston which is arranged and guided between the long sides of the rectangular section, seen from above, by the release spring, which acts on both the piston and the connecting piece, these parts are loaded against two opposite end faces of the bearing body.

  • This solution offers a multitude of possibilities when choosing the support and pivot points, so that a more precise specification of the tripping characteristic is possible.
  • the holder according to the invention is made up of particularly few parts, which are also easy to manufacture, so that extremely cost-effective series production of this holder is possible.
  • the sloping sliding surface improves the control of the vertical release characteristic.
  • a further improvement in the control of the vertical triggering characteristic is possible in that the housing has a downwardly projecting projection which is arranged at a longitudinal distance from the end face of the transverse wall of the housing facing the bearing body and on a substantially normal to the end face of the bearing body aligned bearing surface of the bearing body is supported downwards.
  • this projection can be integrally formed as a nose of the transverse wall or, in an alternative embodiment, can be adjusted in height and / or length to enable a presetting or change of this triggering characteristic.

  • the side faces of the bearing body - as seen from above - are designed in a circular shape to allow the housing to be pivoted in all directions.
  • the bearing body in order to improve the triggering characteristic when the ski is bent, is mounted on the mounting plate so as to be longitudinally displaceable to a limited extent and loaded in the direction of the ski boot by means of a shear spring.
  • a shear spring in order to provide an actuatable means for displacing the bearing body by relieving the thrust spring, which means forms an exit, in particular an emergency exit.
  • This means for displacing the bearing body can be a toggle lever mechanism which acts between the mounting plate and the thrust spring in a simple manner.
  • such a holder should make it possible to easily get in and out of the ski binding.
  • This implementation should be as simple as possible and inexpensive to manufacture
  • the bearing body has a holding lug, by means of which the holder is held at a certain position in the pivoted-up state against the force of the release spring.
  • the base of the connecting piece and the bearing body are supported against one another on a sliding surface and the retaining lug is arranged in the upper end section of this sliding surface.

  • Another advantageous aspect of the present invention results from the use of the holder according to the invention described above as a front or heel jaw of a ski binding. Furthermore, the concept of the present invention provides an embodiment in which the holder according to the invention is used both as a front and a heel of a ski binding. This results in special advantages, since the construction and manufacture of the entire ski binding can be done much more cost-effectively and quickly. Furthermore, this special design makes it possible to allow the lateral release either at the front or rear or at the front and rear. In any case, the side-elastic pivotability of both the front and the rear bracket ensures that the binding can be set with significantly lower release values, and the risk of injury to the skier can therefore be significantly reduced.

This spring force does not affect the horizontal release noticeably.
  • the lateral pivotability of the housing 105 is not restricted, so that the ski boot can be released laterally by the holding part 106 when triggered.
  • a ski binding is composed by two essentially identical holders 101 according to FIGS. 9 to 12. Due to the lateral pivotability of both brackets 101, the setting of the release force can be significantly reduced compared to conventional ski bindings.
  • the lateral pivotability of the housing can, however, be limited by an elastic or rigid stop, so that no side release is possible.
  • this bracket mainly has the function of elastically absorbing lateral blows, whereas the second bracket is mainly responsible for triggering is.
  • the side release can be blocked by a stop on the front or rear bracket. In particular, this blocking can be realized by a suitable increase in the spring characteristic of the release spring.
  • an inclined ramp surface or a nose can be provided on the inside of each treadmill 106'a, 106 * b, which is supported on a counter surface of the bearing body or the mounting plate which is inclined with respect to the vertical, so that a pure lateral pivoting of the holder not possible.
  • the possibility of triggering the holder can be influenced in a targeted manner by the inclination or curvature of the ramp surfaces or counter surfaces. In extreme cases, the side release of this bracket is completely blocked with a vertical ramp or counter surface and only vertical release is possible.
  • the holder according to the present invention can be used both as a front and as a heel of a ski binding.
  • this has the advantage that many components can be constructed identically or similarly.
  • the currently existing standards must be taken into account, e.g. Shoe standards that require a different design of the holding parts 106 for front and heel jaws and a different height of the mounting plate 102. Due to the different force relationships in the area of the toe and in the heel area, differently dimensioned release springs are generally used. In future systems, however, it is possible to design the sole of the ski boot so that exactly identical front and rear mounts can be realized.
  • the entry / exit mechanism for the ski binding can be arranged either from the front or from the rear or from the front and rear, so that the user can choose which of the brackets he brings into the opening position for getting in and out .

Abstract

L'invention concerne une fixation pour solidariser une chaussure de ski et un ski. Ladite fixation est constituée, d'une part, d'une plaque (2, 102) de montage fixée au ski, laquelle présente un corps de support (3, 103) faisant saillie vers le haut et contre lequel vient s'appuyer le boîtier (5, 105) de fixation avec une paroi transversale (7, 107), en direction de la chaussure de ski, et présente un élément (6, 106) de retenue pour la chaussure de ski, d'autre part, d'un élément de traction (8, 108) guidé à travers la paroi transversale (7, 107) du boîtier (5, 105), ledit élément de traction venant s'appuyer sur le côté opposé du corps de support (3, 103) dans le sens opposé à la chaussure et enfin d'au moins un ressort (12a, 12b, 112a, 112b) de déclenchement qui agit entre la paroi transversale (7, 107) et l'élément de traction (8, 108) de telle manière que les éléments (7, 107, 8, 108) sont sollicités contre le corps de support (3, 103) et que le boîtier (5, 105) vient se loger contre le corps de support (3, 103) en contrecarrant la force dudit ressort (12a, 12b, 112a, 112b) et en pivotant autour d'un axe sensiblement vertical. L'élément de traction (8, 108) est conçu - vu de dessus - sous la forme d'un étrier en U présentant une base (9, 109) qui est perpendiculaire au sens longitudinal du ski et qui s'appuie sur le corps de support (3, 103), et deux branches (10a, 10b, 110a, 110b) orientées dans le sens longitudinal du ski, lesquelles sont introduites dans la paroi transversale (7, 107) du boîtier (5, 105) en entourant latéralement le corps de support (3, 103). La base (9, 109) de l'étrier (8, 108) et le corps (3, 103) sont mutuellement supportés par une surface (20, 120) de glissement, au moins partiellement inclinée par rapport à la verticale, surface sur laquelle lesdites pièces (9, 109, 3, 103) sont guidées lorsque l'on fait pivoter le boîtier (5, 105) vers le haut.
