Definitions
- the invention relates to a safety ski binding according to the preamble of claim 1.
- 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 in engagement with the spring-loaded ratchet lever enables the use of a single leg spring which simultaneously acts on the sole holder, which is arranged on a common cross pin of the ratchet lever and control member. Furthermore, the control member itself can cover the ratchet lever and - in the driving position considered - be created for the guide surface and for the front area of the soleplate.
- the features of claim 2 ensure simple guidance between the sole plate and guide plate in a simple construction.
- the pivoting ability of the soleplate is determined in a particularly simple manner.
- the one-piece design of the guide surface and guide plate according to the features of claim ⁇ reduces the number of components required in this area separately.
- claims 7 and 8 allow a particularly favorable design of the control lug or the control member.
- a particularly advantageous form of the control element 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 drawing shows two exemplary embodiments of the safety ski binding according to the invention.
- FIG. 1 is a longitudinal section along the line II in FIG. 2 of a toe piece 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 soleplate
- 4 is a plan view similar to FIG. 3, but with the sole plate 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 in 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 as to be longitudinally displaceable but not detachable.
- a guide groove 4b which runs 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 downward and rearward sloping guide surface 4c is formed on the top of the guide plate 4.
- 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 run converging upwards and each form an angle 0 with the guide surface 4c, which has a size of 15 ° to 90 °.
- the drawing also shows the front area of a sole plate 5, which is pivotably mounted in a known manner on a pivot, not shown.
- a sole plate 5 On the underside of the sole plate 5, wedge-shaped pivot stops 5a, 5b, which converge towards the rear, are provided. The extent of the slope of the wedges is determined so that in the swung-out position of the sole plate 5, a swivel stop 5a or 5b bears against the long side of the tongue-shaped extension 3b of the base plate.
- the front end region of the sole plate 5 is formed 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 bearing block 5c is designed as a shoulder 5f and has the shape of a lying L in cross section .
- the shoulder 5f of the bearing block 5c engages in the guide groove 4b of the guide slot 4, with an upwardly projecting part 5g of the shoulder 5f extends into the extension 4b [the guide groove 4b.
- 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. In side walls 6b, 6c of the Sohienhalters 6 bearing points for the cross pin 11 and a sole he bolt 12 are provided. 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 transverse pin 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 on a first lever arm 14a, which is approximately horizontal in the driving position, one on the cross pin 11 approximately in Area of the longitudinal axis of the sole plate 5 mounted two-armed ratchet lever 14 and acts on the ratchet lever 14 - viewed in the view in Fig.l - 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 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 1a, 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 17 a, 17 b are articulated on the support bolt 10 on the bearing block 5 c of the sole plate 5.
- FIG. 3 shows the ski binding according to the invention in a top view similar to FIG. 2.
- the sole holder 6 and the control member 7 have been omitted, as a result of which the carrier bolt 10, the pawl bolt 11 and the bracket bolt 16, as well as the latch lever 14, the connecting lever 15a, 15b and the bracket 17a, 17b can be seen better.
- 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 exceeded the control nose 4d begins, the control member 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 swivels 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 swivel 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 left boundary wall 7e in this illustration, reaches the control nose 4d (see FIG. 7).
- the sole plate 5 is pivoted further the control member 7 is pushed up against the force of the leg spring 13, the oblique boundary wall 7e sliding up on the flank 4f of the control nose 4d (see FIG. 8).
- the figure shows a second embodiment of the ski binding according to the invention.
- 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, like the guide surface 4c or control lug 4d in the first embodiment, are designed 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 of the same 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. Furthermore, as already mentioned, the tab bolt can 16 wear a sleeve, thereby reducing the frictional forces acting on them. However, this would also reduce the overall frictional forces that occur during the actuation of the binding.
- the ratio of the angles can be ot (b, the control nose 4d with flanks 4e, 4f then having a small angle ⁇ ., For example 30 °, and the control member 7 with boundary walls 7d, 7e having a large angle fi>, for example
- the boundary walls 7d, 7e of the control element also according to the invention, overlap the control nose 4d, which in this case is provided with flanks 4e, 4f which extend in the shape of a pointed roof.
