Definitions

  • the invention relates to a device for the longitudinal adjustment of a ski binding part with a guide rail fastened to the ski, with which a guide plate of the ski binding part which is displaceably guided on the guide rail can be latched in different positions via a latching element, which latching element, viewed in side view, has an upwardly open U-shaped one Form, wherein the web connecting the two legs has locking teeth for engagement in toothed strips of the guide rail and the one leg is provided for actuating the locking element for locking and unlocking and the other leg of one under the influence of at least one thrust spring supported on the guide plate standing piston is acted upon, which piston is provided to support the leg with a first, upper projection on its area facing away from the top of the ski, which thrust spring is supported at the other end on the guide plate of the ski binding part, the latching element being dur ch action of a component of the binding part is held in the locked position when the shoe is not clamped.
  • Such a device for longitudinal adjustment of a ski binding part is shown for example in DE-OS 30 15 478 (see in particular Fig. 10 to 14).
  • the guide rail is provided with rows of holes, in which downwardly projecting projections of the latching element snap into place, which are pressed against the guide rail under the influence of the thrust springs. This is brought about by inclined surfaces on the latching element, which bear against corresponding inclined surfaces of the housing of the ski binding part when the ski boot is not inserted in the ski binding part.
  • one leg of the approximately U-shaped locking element is raised by means of an actuating tool, whereby the projections of the locking element from the row of holes in the guide rail free and the ski binding part can be moved along the guide rail.
  • this embodiment has the disadvantage that the ski binding part must be specially designed and that the locking element must be held up continuously during the adjustment process, so that one-handed operation is not possible.
  • FR-OS 24 51 756 Another device for the longitudinal adjustment of a ski binding part is described in FR-OS 24 51 756.
  • the locking element which is under the influence of a thrust spring, engages in a row of holes in the guide rail by means of projections.
  • the locking element is supported on a downwardly projecting part of the housing of the ski binding part. It is also continuously coupled to a wire bracket, the upper end area of which is accommodated in a recess in the ski binding part.
  • a special tool in the form of a screwdriver with two grooves arranged on the blade and directed against the axis of the screwdriver is guided into the wire bracket and the latching element is thus raised, the screwdriver being pivoted through 90 °.
  • the ski binding part can then be moved along the guide rail. Once the desired position of the ski binding part has been reached, the screwdriver is swiveled back by 90 ° and then pulled out of the wire bracket. As a result, the projections of the locking element snap into the holes in the guide rail as a result of the thrust spring.
  • the ski binding part must be specially designed, and on the other hand that a specially designed tool is required for its adjustment.
  • the invention has now set itself the task of creating a device for longitudinal adjustment of a ski binding part which does not have the disadvantages of known designs and which can be used with ski binding parts of any type, is simple in construction and reliable in operation and can be operated with a single hand, no special tools should be required.
  • the first, upper projection of the piston has on its underside a latching surface on which the latching element can be latched in the raised position, the leg of the latching element associated with the piston preferably engaging under the latching surface.
  • the measures according to the invention ensure that simply lifting the latching element, for example by means of an ordinary screwdriver, pivots it up in the region of the bearing points formed on the guide plate, as a result of which one leg of the latching element latches on the spring-loaded piston. Now the ski binding part can be easily moved into the desired position by hand.
  • the invention provides that the piston has a second, lower projection on its area adjacent to the upper side of the ski, against which the leg of the locking element bears with its support area when the ski boot is not in use. Since only minor structural changes to the piston are required for this, the device is constructed in a very simple manner.
  • This embodiment of the invention is particularly advantageous if the latching surface of the upper projection is designed as a surface which runs obliquely in the direction of the guide plate. This ensures a secure locking of the locking element in the raised position of the same.
  • Another embodiment of the invention provides that the upper projection of the piston is made shorter than the lower projection, and that the leg of the locking element associated with the piston carries at its upper end region a crank toward the piston, so that both projections of the piston underneath the influence of the thrust springs rest on the leg of the locking element.
  • the lower end region of the leg of the latching element associated with the piston each has a support area on the side, which support areas are supported on support lugs bent off the tabs.
  • Another feature of the invention is that the two support areas are curved in an arc and determine the bearing axis of the locking element, and that the locking surface of the upper projection of the piston is rounded concentrically to the bearing axis of the locking element. As a result, the leg of the locking element slides along the locking surface of the projection of the piston during locking and unlocking, so that the material wear can be kept low even with frequent locking and unlocking.
  • Fig.I the adjustment device in side view in section in the locked state when the ski boot is not inserted in the binding
  • Fig.2 in the unlocked position also in side view in section
  • Fig.3 a locking element in oblique view.
  • a guide rail 1 is provided to be fastened on a ski (not shown), the lateral regions of which are bent twice in a manner known per se and thus form guides for a guide plate 2.
  • the guide rail 1 furthermore has a center in its longitudinal direction extending recess la, which is delimited on both sides by toothed strips ib.
  • a ski binding part for example a heel holder 3, is fastened on the guide plate 2.
  • the guide plate 2 which is guided on the guide rail 1 so as to be displaceable in the longitudinal direction of the ski, has on its underside a support shoulder 4 pointing in the direction of the top of the ski, which is provided for supporting a transverse part of a guide element 5 which is U-shaped in plan view for two thrust springs 6 designed as helical compression springs.
  • a piston 7 is also provided, which is preferably made of plastic, is essentially cuboid in shape and is provided with two longitudinal bores 7a for receiving the thrust springs 6.
  • two projections 8, 9 extending transversely to the longitudinal direction of the ski are formed.
  • the projection 8 is arranged on the upper end region of the piston 7, the projection 9 is arranged on the lower end region of the piston 7 and, viewed in the longitudinal direction of the ski, is longer than the projection 8, both the projection 8 and the projection 9 have a perpendicular to the top of the ski Contact surface 8a, 9a for a locking element 10.
  • the latching element 10 When viewed in side view, the latching element 10 is approximately U-shaped and thus has two legs 11, 12 and a central web 10a.
  • the central web 10a of the latching element 10 carries latching teeth which are intended for engagement in the toothed strips 1b of the guide rail 1.
  • the leg 11 of the locking element 10 is made wider than the central web 10a, as a result of which two support regions 11b are formed at the lower end region of the leg 11, by means of which the locking element 10 can be supported on two support lugs 13a of two tabs 13 formed laterally on the guide plate 2.
  • the support regions 11b are curved in the form of an arc in the present exemplary embodiment.
  • a crank 1la is formed by two bends, on which the contact surface 8a of the projection 8 of the spring-loaded piston 7 is supported.
  • the contact surface 9 a of the projection 9 acts on the lower region of the leg 11 opposite leg 12 is provided with an offset 12a, which allows actuation of the locking element 10 by means of an actuating tool, for example a screwdriver.
  • the two tabs 13 of the guide plate 2 form when no ski boot is inserted into the heel holder 3 (in this case the guide plate 2 is in its front end position and the latching element 10 lies on the tabs 13) together with its support lugs 13a to form a bearing point pivotable mounting of the latching element 10. If the latching element 10 is now raised by means of a screwdriver, the blade of which is inserted between the offset 12a of the leg 12 and the guide rail I, the latching element 10 pivots in the area of the tabs 13 and 14 just described Support approaches 13a formed bearings. The offset Ila of the leg 11 displaces the piston 7 against the force of the thrust springs 6 via the projection 8.
  • the latching surface 14 is formed over the entire width of the piston 7 and is preferably curved in an arc shape and viewed in a side view, the center point of this curvature being determined by the support of the support regions 11b of the latching element 10 on the support lugs 13a.
  • the locking element 10 is now held in its raised and unlocked position via its leg 11, which presses the piston 7 against the underside of the guide plate 2. Now the binding on the ski-fixed guide rail 1 can be moved into the desired position without the locking element 11 having to be held in its raised position. Once the desired position of the heel holder 3 on the ski-fixed guide rail 1 has been reached, a short pressure on the leg 12 of the latching element 10 is sufficient to latch it in turn in the toothed strips 1b of the guide rail 1.
  • the invention is not restricted to the exemplary embodiment shown. Further modifications are conceivable without leaving the scope of the scope of protection. It is thus possible to design the leg of the latching element which is supported on the tabs of the guide plate when the ski boot is not in use, even without an offset and as a straight leg. However, this requires a reduction in the vertical dimension of the contact surface of the projection with a constant swivel angle during the lifting of the latching element for unlatching. Furthermore, it is possible not to provide an obliquely extending latching surface on the projection of the piston, as a result of which an edge of the projection then interacts with the upper end region of one leg of the latching element.
