Definitions

  • the invention relates to a safety ski binding according to the preamble of claim 1 or 2.
  • Such a ski binding is already known and is described in AT-PS 387 151.
  • the compensation of the play between the binding body and the guide rail is achieved in that the pressure spring is bent upwards when the binding body is locked and with this bulge presses the base plate of the binding upwards.
  • the pressure spring also fulfills the function of compensating for play, so that part of the force is ineffective when the pressure is applied even when the spring is bent. It is therefore necessary to dimension the pressure spring more strongly in order to achieve the effect required for the pressing. This also increases the effort required for the adjustment.
  • the object of the invention is to eliminate this disadvantage and to create a ski binding in which compensation for the play between the binding body and the guide rail is effected independently of the pressure spring.
  • claim 3 improves the flow of force from the resilient sections or the leaf springs into the binding body.
  • FIG. 1 to 4 show a first embodiment of a safety ski binding according to the invention, FIG. 1 being a partially sectioned side view and FIG. 2 being a cross section along the line II-II in FIG. 1.
  • Fig. 3 is a vertical longitudinal central section along the line III - III in Fig. 4 and
  • Fig. 4 is a plan view of the spring cage.
  • FIG. 5 shows a second embodiment in a representation similar to FIG. 3.
  • the safety ski binding shown in FIGS. 1 and 2 has an upwardly open, U-shaped guide rail 2, which is fastened with its web 2a on the top of a ski 1 by means of screws, not shown, and on which a binding body 3 with its base plate 3a in Longitudinal direction of the ski 1 is guided.
  • the base plate 3 a can be fixed in a manner known per se for adapting the binding to ski boots of different lengths in the respectively desired position by means of an adjustment catch 4.
  • the two legs 2b of the guide rail 2 carry inwardly projecting flanges 2c.
  • the base plate 3a is provided with lateral guide flanges 3b, which - in the assembled state of the binding body 3, as will be described further - are pressed against the flanges 2c of the guide rail 2.
  • the base plate 3 a has two pressure springs 5 accommodated in a spring cage 6 and can be displaced away from the ski boot on the guide rail 2 against the force of these pressure springs 5.
  • the pressure springs 5 are between a shoulder 3c of the base plate 3a and the rear transverse wall 6a of the spring caged 6 clamped.
  • the transverse wall 6a has an upper boundary surface 6h.
  • the spring cage 6 is made of plastic and is formed in one piece.
  • the bottom 6b of the spring cage 6 consists of three parallel longitudinal ribs, namely a central rib 6c and two lateral ribs 6e (see FIG. 4). Recesses 6d extend between the two lateral ribs 6e and the central rib 6c and extend in the longitudinal direction of the ski.
  • the two lateral longitudinal ribs 6e are, as shown in FIGS. 3 and 4, tapered in a section 6e1 of their longitudinal extent, convexly curved downward and thus resilient.
  • the transverse wall 6a of the spring cage 6 is raised relative to its longitudinal ribs 6e in two sections 6h1 and 6h2, which form the boundary surface 6h. Between the two sections 6h1 and 6h2 of the boundary surface 6h, a groove 6i is recessed. A guide rib 3e of the base plate 3a is guided in this groove 6i.
  • two lateral, approximately T-shaped approaches 6g, each provided with two resilient flanges 6f are formed on the spring cage 6 symmetrically to the vertical longitudinal center plane.
  • the two lateral, downwardly convex resilient ribs 6e of the spring cage are tensioned.
  • the two sections 6h1 and 6h2 of the raised boundary surface 6h of the transverse wall 6a lie against the bottom surface 3d of the base plate 3a and press them up until the guide flanges 3b rest against the flanges 2c of the rail 2 (see FIG. 2).
  • the spring cage 6 is slidably guided by means of the two flanges 6f of its lugs 6g on the legs 2b of the guide rail 2 when the base plate 3a is moved and is centered relative to the guide rail 2 at the same time
  • the binding body 3 takes up relative to the guide rail 2 - in the longitudinal direction of the ski considered - a somewhat inclined position.
  • the binding body 3 When the ski boot is inserted, the binding body 3 is pressed upwards by the two pressure springs 5 and downwards at the front. As a result of the inclined front end face of the projection 3c, the resilient ribs 6e are tensioned somewhat more than their pretensioned state. However, the friction caused by this deformation is negligible compared to that caused by the frictional forces during the adjustment of the binding body 3 during ski deflections, so that a compensation of ski deflections can take place practically without negative influences on the two resilient ribs 6e.
  • the underside of the spring cage 6 is flat, and the two lateral longitudinal ribs 6e each carry a downwardly convex leaf spring 6e2, which is fastened by means of two rivets 6b1 to the bottom 6b of the spring cage 6 .
