Definitions

  • the invention relates to a safety ski binding according to the preamble of claim 1.
  • DE-OS 30 15 478 describes a safety ski binding with an elastic pressure device, which also enables compensation for 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 object of the invention is to create a safety ski binding of the type mentioned at the outset which compensates for the play 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. This deformation increases the frictional force generated during a ski deflection, but 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 the occurrence of any appreciable 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 longitudinally extending web 6c, which is formed by two elongated recesses 6d in the bottom 6b so as to be resiliently convex downwards.
  • 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.
