Definitions

  • the invention relates to a toe of a safety ski binding according to the preamble of the main claim.
  • the latching device comprises a spring-loaded latching roller which engages in a latching depression provided on the coupling and thus tries to keep the four-bar linkage in its normal position.
  • the lever has a concave curve, which corresponds in its central region to the locking trough in the coupling and is also acted upon by the locking roller.
  • the central area of the curve is followed on both sides by mirror-like sections which protrude from the corresponding sections of the locking recess in the coupling.
  • This toe piece has the advantage of a simple and robust construction compared to more well known toe pieces with a four-bar linkage. In practice, however, it has been shown that the devices for releasing the side jaws in this front jaw are in need of improvement both in terms of their manufacture and their function.
  • the task is to improve the front jaws in terms of their manufacture and their function.
  • this is achieved in that the two-armed lever carries a driver at the ends of its arms and in that in the vertical plane of symmetry of the jaw a base plate-fixed stop is used to interact with the drivers.
  • the stop can be connected indirectly to the base plate via a housing part.
  • the latching device can extend below the stop, so that the toe piece has a compact design.
  • the carriers are expediently designed as pins which extend upwards parallel to the axis of the lever, so that the components can be kept simple and inexpensive to produce.
  • the front jaw comprises a housing which consists of a base part 1 to be fastened to the ski and a cover part 2 held thereon.
  • the base 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 invention.
  • 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.
  • the tread plate 4 is made in one piece with the coupling 7, as can be seen in FIG. 1. 2 still has two screw holes 14 in Recognize base part 1 and two corresponding mounting holes 15 in the step plate 4.
  • the four-bar linkage is held in its normal position by a latching device.
  • a pivotable centering part 19 in a horizontal plane is under the influence of a helical tension spring 16 and holds the four-bar linkage in its normal position via the driver 26 mounted in the coupling 7.
  • the tension coil spring is suspended from a holding plate 17 which is adjustably held on a screw 18 in the housing.
  • the pivot pins 10, 11 of the coupling 7 on the levers 5, 6 each carry a side jaw 12 or 13.
  • These side jaws are designed as two-armed levers, the second arm or 31 of which ends in a rounded tip.
  • the arms 30, 31 normally abut a two-armed lever 32 mounted on the driver 26 on its end face sections 33 and 34, so that the side jaws 12, 13 cannot move outwards relative to the coupling (see FIGS. 2 and 3 ).
  • the end face sections 33, 34 of the lever 32 are curved around the axis of the driver 26 and end on the trigger side with sharp edges.
  • the respectively adjoining end surface section 35 or 36 is concavely curved and serves as a restoring surface for the arm 30 or 31 of the respective side jaw 12 or 13 descriptive serve as support surfaces and are separated from each other by a central recess 39 of the lever 32.
  • the lever 32 carries a pin 40 or 41, which serves as a control part or driver and extends upwards. These pins serve to interact with a fixed stop 42 lying in the vertical plane of symmetry of the fore-jaw.
  • This stop forms Part of an extension 43 extending from the cover cap 2 into the interior of the front jaw. The free end of this extension merges into two pins 44 which serve to connect the cover part to the base part 1.
  • the extension 43 serves as an abutment for the end face sections 37, 38 of the lever 32.
  • the length of the end face sections 37, 38 corresponds to the pivoting path of the four-bar linkage to the side.
  • the individual parts of the toe piece normally assume their position shown in FIGS. 1 and 2. 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 in FIG. 2, for example into that shown in FIG. 3 Location. During this pivoting in the so-called elastic range, the side jaws 12, 13 do not move with respect to the coupling 7 of the four-bar linkage because they are supported with their arms 30, 31 on the lever 32 mounted on the coupling 7. When the force decreases, the four-bar linkage returns to the starting position according to FIG. 2 under the influence of the helical tension spring 16.
  • Fig. 3 shows the front jaw in a position immediately before the release of the side jaw 13. Due to the constant application of force and the resulting pivoting of the four-bar linkage, the pivoting of the pin 40 on the stop 42 results in the lever 32 being pivoted relative to the coupling 7 about the driver 26 with respect to the clockwise representation. This is made possible by the fact that the support surface 38 has previously been released from its abutment on the shoulder 43. At the end of the pivoting-out movement of the lever 32, the free end of the arm 31 of the side jaw 13 comes free from the end face portion 34 of the lever 32, so that the side jaw can swing open about the pivot pin 11, which is shown in FIG. 4. In this position, the shoe can be released from the toe piece.
