Definitions

  • the invention relates to a safety ski binding according to the preamble of claim 1.
  • DE-OS 31 02 010 is further removed from the considered state of the art insofar as the entire front jaw can be pivoted about a transverse axis, while in the above-mentioned application forming the prior art (AT-PS 382.084) as well as in the Safety ski binding forming the subject matter of the invention, the sole holder is designed as an independent component and is arranged to be pivotable about a transverse axis.
  • the present invention has set itself the goal of making a toe of the type mentioned in its construction even more compact and of reducing the number of individual components.
  • control member is directly engaged with the pawl lever acted upon by a spring
  • the use of a single leg spring is made possible, which simultaneously acts on the sole holder, which is arranged on a common cross pin of the pawl lever and control member.
  • the control member itself can provide a cover for the ratchet lever and — viewed in the driving position — for the guide surface and for the front area of the soleplate.
  • claims 7 and 8 allow a particularly favorable design of the control lug or the control member.
  • a particularly advantageous form of the control member is protected by the features of claim 9.
  • a simple and safe interaction between the control lug and the control element is characterized by the features of claim 10.
  • the features of claim 12 allow an arbitrary opening of the toe.
  • the drawing shows two exemplary embodiments of the safety ski binding according to the invention.
  • FIG. 1 is a longitudinal section along line II in FIG. 2 of a toe according to the invention in the driving position
  • FIG. 2 is a partially sectioned top view thereof
  • FIG. 3 is a top view in the driving position, omitting the components covering the sole plate
  • FIG. 4 3 is a top view similar to FIG. 3, but with the soleplate pivoted
  • FIG. 5 is a longitudinal section through the toe in an arbitrary release
  • FIGS. 6 to 8 show details of the ski binding in the driving position and with a side release
  • FIG. 9 is a longitudinal section through a second embodiment of the ski binding according to the invention.
  • front rear, left and right refer to the driving position, i.e. front means towards the ski tip etc.
  • a base plate 3 is fastened on a ski 1 by means of only indicated screws 2.
  • the base plate 3 has guide rails 3a which extend in the longitudinal direction of the ski and project upwards on both sides. In the area of the longitudinal axis of the ski, a tongue-shaped extension 3b of the base plate 3 projects to the rear.
  • a guide plate 4 is mounted on the base plate 3 by means of its base 4a so that it can be moved longitudinally but not lifted off.
  • a guide groove 4b which extends parallel to the ski surface and transversely to the longitudinal axis of the ski, is excluded.
  • the guide groove 4b has an upward widening 4b at its front end.
  • a control lug 4d rises with two flanks 4e, 4f which are symmetrical with respect to the central longitudinal axis of the control lug 4d (see in particular FIGS. 6 to 8).
  • the two flanks 4e, 4f converge upwards and each form an angle a with the guide surface 4c, which has a size of 15 ° to 90 °.
  • a sole plate 5 which is pivotally mounted in a known manner on a pivot, not shown.
  • the sole plate 5 is provided with wedge-shaped pivot stops 5a, 5b which converge towards the rear. The extent of the slope of the wedges is determined so that in the pivoted-out position of the sole plate 5, a swivel stop 5a or 5b bears against the longitudinal side of the tongue-shaped extension 3b of the base plate.
  • the front end region of the sole plate 5 is designed as a bearing block 5c for a support bolt 10 and a cross bolt 11.
  • the bearing block 5c has an approximately rectangular recess 5e in its area facing the ski 1 and is delimited at its shoe-side end by a wall 5d.
  • the front area of the pedestal 5c is designed as a shoulder 5f and has the shape of a lying L in cross-section Extension 4b i of the guide groove 4b extends.
  • a sole holder 6 is pivotally mounted on the cross bolt 11. At its rear end, it has a receiving area 6a for a ski boot, not shown. Bearing points for the cross bolt 11 and a sole holder bolt 12 are provided in side walls 6b, 6c of the sole holder 6. The sole holder 6 is open towards the front. Furthermore, at least one locking point 6d for a leg 13a of a leg spring 13 is provided in the sole holder 6, the windings 13c of the leg spring 13 running around the cross bolt 11. The leg spring 13 acts on the sole holder 6 in its closing direction.
  • a second leg 13b of the leg spring 13 is supported in a first lever arm 14a, approximately horizontal in the driving position, of a two-armed latch lever 14 mounted on the cross bolt 11 approximately in the region of the longitudinal axis of the soleplate 5 and acts on the latch lever 14 in the view in FIG 1 viewed in the counterclockwise direction.
  • the second lever arm 14b of the pawl lever 14 extends obliquely forward and upward, its front end region 14c resting on a bearing surface 7a of a control element 7 articulated on the pawl pin 11.
  • a front edge 7b of the control member 7 rests in the driving position of the binding on the guide surface 4c of the guide plate 4.
  • control member 7 On the side facing the guide plate 4, the control member 7 has an exemption 7c, which is closed laterally by outward and downward sloping boundary walls 7d, 7e is, the bevel of each includes an angle with a size of 15 ° to 90 ° with the cutting plane running normal to the guide surface 4c.
  • Two symmetrically arranged kidney-shaped connecting levers 15a, 15b with their upper end regions 15c, 15d are mounted on the sole holder bolt 12.
  • Lower end regions 15e, 15f of the connecting levers 15a, 15b are connected to tabs 17a, 17b by means of a tab bolt 16.
  • the tab bolt 16 can be provided with a sleeve, not shown in the drawing.
  • the tabs 17a, 17b are articulated via the support bolt 10 on the bearing block 5c of the sole plate 5.
  • Fig. 3 shows the ski binding according to the invention in plan view similar to Fig. 2
  • the sole holder 6 and the control member 7 have been omitted, whereby the support pin 10, the pawl pin 11 and the tab bolt 16, and the latch lever 14, the connecting lever 15a, 15b and the tabs 17a, 17b are easier to see.
  • the sole plate 5 is pivoted. It takes the control member 7 with it, which slides with its front edge 7b along the guide surface 4c of the guide plate 4. As soon as one of the two inclined boundary surfaces 7d, 7e of the control element 7 has reached or begins to exceed the control lug 4d, the control element 7 is pivoted up and takes the pawl lever 14 against the force of the leg spring 13. As a result, the tab bolt 16 is released from the horizontal lever arm 14a of the ratchet lever 14, and the sole holder 6 pivots up under the action of the shoe. The procedure will be described in more detail later with reference to FIGS. 6 to 8.
  • FIG. 6 to 8 show the interaction of the control lug 4d of the guide plate 4 with the control member 7 and its oblique boundary walls 7d, 7e.
  • the control member 7 In the driving position (see FIG. 6), the control member 7 is in its central position. After a certain pivot angle of the sole plate 5, which is dependent on the shoe length, one of the two oblique boundary walls 7d, 7e, in the case shown the boundary wall 7e on the left in this illustration, reaches the control nose 4d (see FIG. 7). When the sole plate 5 is pivoted further, the control member 7 becomes counter to the force of the leg spring 13 pushed up, the sloping boundary wall 7e sliding up on the flank 4f of the control nose 4d (see FIG. 8). The different sizes of the angles .alpha.
  • the guide plate 24 is designed so that the arbitrary release of the toe is possible in a particularly simple manner.
  • a button 8 is pivotally mounted in the guide plate 24 about a transverse axis 18.
  • the button 8 has on its upper side a guide surface 8a and a control lug 8b, which are designed like the guide surface 4c or control lug 4d in the first exemplary embodiment according to FIGS. 1 to 8.
  • the button 8 is equipped on its upper side with a recess 8c for a ski pole tip or for a finger.
  • a recess 24g is provided in the guide plate 24 for pivoting the button 8.
  • the invention is not tied to the two exemplary embodiments shown in the drawing and described above. Rather, several modifications thereof are possible without leaving the scope of the invention. For example, it would be possible to use two symmetrically arranged leg springs instead of one leg spring, or to form a symmetrically arranged spring in one piece.
  • the tab bolt 16 can carry a sleeve, as a result of which the frictional forces acting on it are reduced. However, this would also reduce the overall frictional forces that occur during the actuation of the binding.
  • the ratio of the angles a ⁇ can be, in which case the control nose 4d with flanks 4e, 4f which have a small angle a, e.g.
  • control member 7 with boundary walls 7d, 7e which have a large angle ⁇ , e.g. 80 °, are formed.
  • boundary walls 7d, 7e of the control member also according to the invention, overlap the control nose 4d, which in this case is provided with flanked edges 4e, 4f.
