Definitions

  • the present invention relates to front jaws for safety ski bindings according to the preamble of the main claim.
  • Such front jaws are already known from various publications (e.g. DE-AS 1809889 and 1910808), but have so far not been used in practice. Compared to other known toes of the genus on the market, they have the advantage that their side jaws follow a pivoting movement of the ski boot in the elastic region of the front jaw, so that friction between the side jaws and the sole of the shoe is avoided in this area. As a result, there is only a low sensitivity to the pressure exerted by the heel holding device and a relatively good resetting behavior.
  • each side jaw is assigned a locking part designed as a locking pin and that the lever on the extension of the side jaw is a latch lever which engages behind the locking pin and for which a base plate-fixed stop is provided.
  • the locking member is a axially parallel to the side jaws centrally mounted to the support member lever and in that a base plate fixed stop is provided for this lock lever on both sides of the plane of symmetry of the jaw, respectively.
  • each support lever can carry an axially parallel guide pin and a link can be provided in the support member for each guide pin, which prevents the support lever from reaching the extended position and lengthening of the side jaw when it is pivoted.
  • the support levers are expediently held in their normal position so that there is good operational safety even in rough driving conditions.
  • the support levers are held in their normal position by a cam disk, which can be displaced in the longitudinal direction of the jaw against the force of a spring.
  • a particularly simple design is achieved in that the spring of the Rasteinrichtunq also loads the cam.
  • the front jaw shown in FIGS. 1 to 4 has a housing 1, which consists of a base part 2 which can be fastened to a ski in the usual way and a cover part 3 held thereon.
  • the levers 6, 7 of a four-bar linkage, the coupling of which is designated 8, are mounted on two vertical axes 4, 5 provided in the housing.
  • the coupling serves as a support member for two side jaws 9, 10, which are mounted on the levers on one of the pivot pins 11 and 12 of the coupling, respectively.
  • the coupling is constructed from two stamped sheet metal pieces in Fi g 81 shown in section .1 formed 82, which are mounted parallel to each other at a distance to the articulation pivot 11, 12th Fi g . 3 shows the elevation of the sheet metal stamping 82.
  • a pin 13 axially parallel to the hinge pivot. 11 12 stored. This carries a locking lever 14, a guide bush 15 with a flange 16 and a locking roller 17. This locking roller engages in the normal operating state of the toe in a locking recess which consists of two mirror-like intersecting levers 18, 19. Each lever is on an axis 20 or 21
  • Both levers are interposed by an axially parallel pin 22 and a pressure piece 23 under the influence of a helical compression spring 24, which in turn is supported on the housing 1 with the interposition of a nut 25 and an adjusting screw 26 (see in particular FIG. 3).
  • the side jaws 9, 10 are extended beyond the pivot pins 11, 12. Each of these extensions is. because a lever 27 or 28 is mounted, via which the side jaws are supported on the locking lever 14.
  • the locking lever has two gradations 29, 30.
  • a stop 41 or 42 fixed to the housing is provided for the locking lever on both sides of the plane of symmetry of the jaw. In the present embodiment, these stops are on the axles 20 and 21 for the levers 18, 19 forming the locking recess.
  • Each of the levers 27, 28 supported on the locking lever 14 also has an axially parallel guide pin 31 or 32.
  • a backdrop 33 or 34 is provided in the sheet metal punch 81, the purpose of which is described in detail below.
  • a spiral spiral spring 35 is mounted on the pin 13, which engages with the free ends 36 behind the guide pins 31, 32 and thus resiliently holds them in their normal position according to FIG. 2.
  • a cam disk 37 which is mounted on the pin 22 and is therefore loaded by the helical compression spring 24.
  • the guide pins 31, 32 thus protrude from the levers 27, 28 supporting them both upwards and downwards, the upper ends of each projecting into a link 33 or 34 of the sheet-metal punched piece 81, while the lower ends protrude of the cam disk 37 extend into the vicinity of the flange 16 of the guide bush 15.
  • the levers 6, 7 of the four-bar linkage are formed from substantially U-shaped sheet metal stampings, which are shown in FIGS. 2 to 4 in section through the webs.
  • Each leg has an incision through which the axis 20 or 21 can extend, which are arranged fixed to the housing and each carry a lever 18 or 19, which together form the locking trough for the locking roller 17.
  • the scenes 33, 34 in the sheet metal stamping 81 are dimensioned such that when the side jaws 9, 10 are pivoted, the articulation point of the support levers 27, 28 on these jaws does not reach the connecting straight line between a pivot pin 11 or 12 and the corresponding guide pin 31 or 32 can (see Fig. 4). This results in a safe resetting of the side jaw, be it under the influence of the spring 35 or the cam disk 37. With the resetting of the support lever, the locking lever 14 is also reset, so that no special retaining spring or return spring is necessary for this.
  • the toe piece shown in FIGS. 5 to 7 differs only slightly from the toe piece described above.
  • the same reference numbers are therefore used for the same parts. In this respect, the description of the structure of the toe piece is not repeated.
  • a coupling 44 which in turn is formed from two sheet-metal stampings, which are mounted parallel to one another at a distance on the pivot pins 11, 12.
  • a side jaw 45 or 46 which, on their extension 47 or 48 provided according to the invention, carries a lever 49 or 50 which is designed as a ratchet lever.
  • the sheet metal stampings forming the coupling 44 are parallel to the pivot pins 11 and 12 two locking pins 51, 52 are mounted, which are normally engaged behind by a ratchet lever 49 or 50, thereby preventing the side jaws 45, 46 from swinging out.
  • The. Ratchet levers are held in their locked position under the influence of a spiral spiral spring 53.
  • Each side jaw is still under the influence of a return spring 54 or 55, which is also designed as a spiral spiral spring and whose support leg is hooked on the coupling 44.
  • each pawl lever 49, 50 merges into a sliding surface 56 or 57, which are provided for interaction with a ski-fixed stop.
  • the axles 20, 21 serve directly as ski-fixed stops in this construction.
  • Figure 5 shows the front jaw in its normal position.
  • the four-bar linkage is pivoted about the axes 4, 5 at the moment when a force exceeding the pretension of the helical compression spring 24 is applied to one of the side jaws 45 or 46. If this force application is of a suitable size and duration, it takes place on
  • the ratchet lever here
  • the ratchet lever 49 strikes the axis 20 with its sliding surface 56, which leads to the ratchet lever being unhooked from the locking pin 51.
  • the side jaw 45 is released and can pivot into its release position in accordance with FIG. 7, which enables the ski boot to be released laterally.
  • the pivoting of the side jaw takes place against the resistance of the return spring 54, so that after the shoe is released the side jaw returns to its normal position.
  • the ratchet lever connected to the side jaw which is under the influence of the spring 53, strikes the locking pin 51 and engages behind the locking pin when the side jaw reaches the end position. The toe then resumes its normal position shown in FIG. 5 with the simultaneous resetting of the quadrilateral joint.
