Definitions

  • the invention relates to a safety ski binding according to the preamble of claim 1.
  • DE-A-30 15 478 describes a safety ski binding with an elastic pressing device, which also enables compensation of play between the binding body and the guide rail in the vertical direction.
  • the binding body has an inclined surface in its lower region, which is in contact with an inclined surface of the adjustment catch, with which the position of the binding body on the guide rail is determined, under the influence of at least one pressure spring acting in the longitudinal direction of the ski, if no ski boot is clamped in the binding.
  • the inclined surfaces are designed in such a way that under the influence of the pressure spring they result in a force component that pushes the binding body upwards in the guide rail until there is no more play. In this position, the binding body is thus held in position relative to the guide rail by frictional connection.
  • the binding body With the ski boot inserted, i.e. in the loaded state, however, the binding body is pushed back against the force of the pressure spring, which creates a space between the adjustment catch and the binding body, viewed in the longitudinal direction of the ski. As a result, however, the force acting on the two inclined surfaces is canceled and the game mentioned at the outset arises between the binding body and the guide rail. Now the binding body in ski deflections against the force of the pressure spring can be realistically moved to the adjustment catch in a known manner to the rear.
  • the spring acting on the piston merely serves to position the binding body via its base plate in relation to the guide rail.
  • the magnitude of the force of the spring acting on the piston there is no statement in the latter publication. For this reason, it cannot be assumed that a game existing between the binding body and its guide rail should be canceled. This is all the less the case since both of the printed publications dealt with come from the same applicant and when the latter FR-OS was deposited, the first-mentioned DE-OS was already published.
  • the invention has for its object to provide a safety ski binding of the type mentioned, which compensates for the game between the binding body and the guide rail in a different way.
  • the binding body is pressed upward over the side walls of the spring cage with the force of its resilient element until the binding body no longer has any play in the guide rail in the vertical direction.
  • the play of the binding body in the guide rail is compensated in a very simple way as long as it is in the unloaded state.
  • the resilient element is also deformed. Although this deformation increases the frictional force that arises during a ski deflection, it is negligible compared to the frictional forces that have to be overcome by the pressure springs.
  • the measures according to the invention can be used to adjust the binding body against the force of the pressure spring during ski deflections without generating any significant additional frictional forces.
  • the resilient element can be produced by two elongated recesses in the bottom of the spring cage. This facilitates water drainage and also reduces the weight of the spring cage.
  • FIG. 1 shows a safety ski binding according to the invention in longitudinal section and FIG. 2 shows the binding in cross section. 3 and 4, the longitudinal section and the bottom view of the spring cage are shown.
  • FIGS. 1 and 2 A safety ski binding is shown in FIGS. 1 and 2.
  • a guide rail 2 On the top of a ski 1, a guide rail 2 is fastened by means of screws, not shown, on which a binding body 3 is displaceably guided in the longitudinal direction of the ski 1 and in a manner known per se for adapting the binding to differently long ski boots in the desired position by means of a Adjustment catch 4 can be determined.
  • the binding body 3 has a pressing device which consists of two pressing springs 5 in a spring cage 6 having two side walls 6e, and is displaceable against the force of the pressing springs 5 on the guide rail 2, the pressing springs 5 between a shoulder 3a of the binding body 3 and the rear Wall 6a of the spring cage 6 are clamped.
  • the spring cage 6 is made of plastic and has in the middle part of its bottom 6b a longitudinal web 6c, which is formed by two elongated recesses 6d in the bottom 6b in a resiliently convex manner.
  • the web of the spring cage 6 thus forms a resilient element 6c.
  • the side walls 6e of the spring cage 6 come into contact with the binding body 3 along the surface 3b and also push it up until it lies against the rail surfaces 2a and has no more play in the guide rail 2.
  • the Binding body 3 pushed up front and back down.
  • the binding body 3 is in a somewhat inclined position relative to the guide rail 2, viewed in the longitudinal direction of the ski, the resilient element 6c being deformed. This deformation, however, is negligible compared to the frictional forces that arise during an adjustment of the binding body 3 during ski deflections, so that a compensation of ski deflections can take place practically without negative influences by the spring element 6c.

Claims (3)

  1. Fixation de sécurité pour ski, munie d'un corps de fixation qui est mobile dans le sens longitudinal du ski, dans une glissière de guidage, peut être arrêté dans différentes positions, au moyen d'un cran réglable, et est soumis à l'influence d'au moins un ressort de pression agissant dans le sens longitudinal du ski, et pourvu d'un dispositif de compensation d'un jeu présent, dans le sens de la hauteur, entre le corps de fixation et la glissière de guidage, caractérisée par le fait que le ressort de pression (5) est retenu dans une cage (6) de ressort présentant deux parois latérales (6e), et dans ou sur le fond (6b) de laquelle est respectivement prévu un élément (6c) à action élastique vers le bas qui, à l'état soulagé, pousse le corps de fixation (3) vers le haut, contre la glissière de guidage (2), par l'intermédiaire des parois latérales (6e) de la cage (6) de ressort ; et par le fait que, à l'état chargé, c'est-à-dire lorsqu'une chaussure de ski est engagée, le corps de fixation (3) prend par rapport à la glissière de guidage (2), en considérant le sens longitudinal du ski, une position inclinée de l'avant vers l'arrière et ayant pour effet de déformer l'élément élastique (6c).
  2. Fixation de sécurité pour ski, selon la revendication 1, caractérisée par le fait que la cage (6) de ressort est ménagée d'une seule pièce en un matériau élastique, de préférence une matière plastique, l'élément élastique étant réalisé sous la forme d'une nervure (6c) qui s'étend dans le sens longitudinal, dans la partie centrale du fond (6b), et est convexe vers le bas.
  3. Fixation de sécurité pour ski, selon la revendication 1, caractérisée par le fait que l'élément élastique est formé par au moins un ressort distinct, prévu à la face inférieure du fond, de préférence par une lame de ressort.
