Definitions

  • the innovation relates to front jaws for safety ski bindings according to the preamble of the main claim.
  • Such known front jaws as e.g. DE 3343943 A1 shows, compared to further known generic toe pieces, have the advantage of better restoring behavior due to more favorable friction conditions.
  • the disadvantage of these front jaws is their relatively large design effort, which means that they are not easy and inexpensive to manufacture.
  • the front jaw comprises only a small number of individual parts, which are also still uncomplicated.
  • the centering part for hanging the spring end has a transverse elongated hole which widens symmetrically toward the center on the spring connection side. In this way, a more favorable tension curve of the spring is achieved during pivoting out, since the moment arm of the spring force decreases with increasing pivoting out.
  • the incision of the centering part which produces the fork tines expediently widens symmetrically toward the inside. This also has a favorable influence on the voltage profile of the holding force and, moreover, increases the protection against icing of this cam gear-like connection with the driver of the coupling.
  • the helical tension spring can be connected to the part held on the ski by means of a screw gear, so that the prestressing of the spring can be adjusted.
  • the front jaw comprises a housing which consists of a base part 1 to be fastened on the ski and a cover part 2 held thereon.
  • the basic part extends with respect to the illustrations to the right beyond the cover part and forms at its free end a claw 3 for holding the free end of a pivotable step plate 4, which is known per se and is not the subject of the present innovation.
  • the housing receives a four-bar linkage, which consists of the levers 5,6 and the coupling 7.
  • the levers are each mounted on an axis 8 or 9 extending at right angles to the ski plane in the housing.
  • the pivot pins of the coupling on the levers are labeled 10 and 11 respectively. They lie parallel to the axes 8, 9 and at the same time each carry a side jaw 12 or 13.
  • the control of the side jaws for releasing a ski boot can take place in a suitable known manner and is therefore not shown and described.
  • 2 still shows two screw holes 14 in the base part 1 and two corresponding mounting holes 15 in the step plate 4.
  • the step plate 4 is made in one piece with the coupling 7, as shown in FIG. 1.
  • a tension spring 16 is provided which is suspended from a holding plate 17.
  • the holding plate has an internal thread into which the shaft of a screw 18 is screwed, which is supported with its head on the cover part 2.
  • the holding plate 17 is movable in the housing only in the longitudinal direction of the screw shaft. With its operative end, the tension coil spring 16 engages a centering part 19 which, for this purpose, has a transverse elongated hole 20 (see FIG. 2) which widens symmetrically towards the center on the spring connection side.
  • the centering part 19 is formed mirror-like in relation to the central longitudinal plane of the toe piece.
  • the tension spring Under the influence of the tension spring, it is usually on middle longitudinal plane of the front jaw symmetrically and parallel to the axes 8.9 housing-fixed bolts 21.22.
  • the centering part 19 At its free end, the centering part 19 is forked by an incision 23.
  • the fork tines thus formed are designated 24 and 25.
  • a driver 26 engages in the incision, which is designed as a pin and is fastened in the middle of the coupling 7 to the coupling parallel to the pivot pins 10, 11.
  • the incision 23 of the centering part 19 widens symmetrically towards the inside, as can be seen in FIGS. 2 and 3.
  • the front jaw is shown in its normal position. If a force is now transmitted from a ski boot, not shown, to the side jaw 13, for example, which exceeds the pretension of the helical tension spring 16, the four-bar linkage swivels downward with respect to the illustration down to the position shown in FIG. 3 at most. During this pivoting in the so-called elastic range, the side jaws 12, 13 do not move relative to the coupling 7 of the four-bar linkage. The practically abrupt release of the ski boot when the force is applied continuously by opening the side cheek lying in the direction of movement takes place by means of a control which is dependent, for example, on the pivoting path of the four-bar linkage and which, as already mentioned above, is not the subject of the present innovation. When the force decreases, the four-bar linkage returns to the starting position according to FIG. 2.
  • the pin 26 in the coupling 7 takes the centering part 19 with it, which pivots about one of the bolts 21, 22 depending on the direction of loading.
  • the helical tension spring 16 is further tensioned.
  • the described design of the elongated hole 20 results in a shortening when pivoting out of the moment arm of the spring shaft, so that the force counteracting the pivoting out can be kept at least approximately constant.
  • the incision 23 of the centering part the tension curve of the holding force is to be influenced, as already mentioned. Furthermore, a free space is created that prevents icing of the pin 26 in the incision 23.
