Definitions

  • the invention relates to a ski safety front binding which has a sole hold-down and a height-adjustable tread plate arrangement for the front part of the sole of a ski boot according to the preamble of claim 1.
  • the sole hold-down device In the case of such safety front bindings, the sole hold-down device must generally be designed to be height-adjustable so that the binding can be adapted to different sole thicknesses.
  • a base plate and a tread plate cooperating therewith via step-like inclined surfaces are provided, wherein the height adjustment of the tread plate arrangement can be carried out by adjusting the tread plate and the base plate in the longitudinal direction of the ski relative to one another.
  • the tread plate is supported on the steps the base plate, which are to be designed accordingly flat.
  • the object of the present invention is therefore to provide a safety front binding with height-adjustable tread plate arrangement which can be easily and sensitively adjusted from the outside to a certain height of the tread plate arrangement with a simple, stable and wear-resistant construction, the overall arrangement being designed to be so compact that it protrudes as little as possible from the ski surface.
  • control surfaces which are additionally adjustable relative to one another are provided on the base plate and the tread plate, but which are effective in the direction that when the control surfaces are adjusted relative to the ski, the base plate and the Footplate in the longitudinal direction of the ski can be moved relative to each other with the result that the desired height adjustment takes place.
  • the relative adjustment of the control surfaces can be brought about very sensitively and sensitively in different ways, where is ensured by a problem-free and precise height adjustment of the step plate arrangement. Since the control surfaces can be arranged in front of or behind the inclined surfaces, the overall footplate arrangement above the ski surface can be made with a very low height. Since the inclined surfaces are designed to be stepless, the height of the tread plate is also stepless according to the invention. If the inclined surfaces are also flat, the relationship between the longitudinal adjustment and the height adjustment is linear.
  • the tread plate forms a fixed part of the ski or the base plate attached to the ski, except for the displaceability to be provided according to the invention perpendicular to the ski surface. Only the base plate, which is preferably provided invisibly under the tread plate, is displaced in the longitudinal direction of the ski when the control surfaces are moved relative.
  • two pairs of inclined surfaces are provided at a distance in the longitudinal direction of the ski, because this ensures a particularly secure guidance of the tread plate on the base plate during longitudinal adjustments, which does not tend to tilt.
  • the tread plate is thus securely supported both at the front and at the rear by inclined surfaces on the base plate, so that the vertical forces exerted by the ski boot on the tread plate are reliably transmitted from the base plate into the ski.
  • a particularly preferred arrangement of the control surfaces is characterized by claim 5. Both the inclined surfaces and the control surfaces are therefore advantageously flat and stepless, so that a continuous and linear adjustment is possible.
  • the self-locking of the adjusting device must be such that even with the strongest forces exerted by the boot on the step plate arrangement, no adjustment of the adjusting device takes place via the inclined and control surfaces.
  • the forces acting on the control slide are transmitted in a particularly advantageous manner from the tread plate to the control slide in the embodiment according to claim 7. This is particularly important if a threaded rod that is sensitive to bending is used to adjust the spool.
  • the leaf spring (s) on the one hand connects the tread plate in the required manner to the base plate or the ski, but on the other hand the tread plate has the required degree of freedom of movement perpendicular to the ski surface and moreover resiliently downwards in the direction is pressed onto the base plate.
  • This spring pressure is transmitted to the base plate via the inclined surfaces, whereby a corresponding longitudinal displacement of the base plate is brought about in the sense that the control surfaces are pressed against one another. In this way, the control surfaces always rest securely against one another, regardless of the adjustment position of the control slide.
  • the embodiment according to claim 9 has the advantage that the leaf springs can easily exert their force on the tread plate downwards. It is particularly preferred if the leaf springs are somewhat bent in a hook shape at the end engaging the tread plate so that they can also hold the tread plate in the longitudinal direction of the ski.
  • a particularly expedient arrangement of the inclined surfaces is characterized by claim 10.
  • a base plate 16 of a safety front binding is fastened to the ski 15 by means of screws 33.
  • a side-releasable front jaw 28 is arranged, which holds the sole 35 of a ski boot 36 inserted into the binding from the side and by means of a sole retainer 27 from above by means of schematically indicated side jaws 34.
  • a step plate arrangement 37 is provided on the ski 15, which consists of a base plate 11 sliding on the ski 15 and a step plate 12 arranged above it, which carries on its upper side a friction set 38 on which the sole 35 of the shoe is slightly Distance from the toe piece 28 lies directly from above.
  • the tread plate 12 On its underside, the tread plate 12 at a distance from one another in the longitudinal direction of the ski has two flat inclined surfaces 20, 20 'which form an angle ⁇ of 30 ° with the longitudinal direction of the ski and rest on complementary inclined surfaces 19, 19' on the upper side of the base plate 11.
  • the inclined surfaces 19, 19 ' are formed on upwardly projecting projections 22, 23 of the base plate 11.
  • the tread plate 12 At its rear end, has an obliquely running slot 39, in which a hook-shaped projection 40 slidably engages from below.
  • the slot 39 is delimited on its front side by an inclined web 41 which carries the inclined surface 20. All inclined surfaces and the slot 39 drop from front to back.
  • the front end surface of the projection 22 is formed according to FIGS. 1 and 2 as a vertically standing, flat control surface 14, which extends at an angle obliquely to the direction of the ski, with a complementary control surface 13 of a control slide arranged below the step plate 12 between the projections 22, 23 21 is present.
  • the control slide 21 has a cross-threaded bore 30 through which a matching threaded rod 31 with a double thread extends, the ends of which are rotatably supported in the side legs of the tread plate 12 according to FIG. 2.
  • a matching threaded rod 31 with a double thread extends, the ends of which are rotatably supported in the side legs of the tread plate 12 according to FIG. 2.
  • the threaded rod 31 extends the end face of the threaded rod 31 to the outside and is provided there with a screwdriver slot 42, which has the special feature that it is open in a V-shape so that the screwdriver is disengaged when the end of the web Element 21 comes into contact with plate 12.
  • the front vertical end surface 24 of the control slide 21 is located on a from the tread plate 12 projecting downward, a vertical rear wall having projection 25, which also carries the above-mentioned front inclined surface 20 'of the tread plate 12. The end surface 24 thus abuts the rear stop surface 26 of the projection 25.
  • the threaded rod 31 is largely relieved of bending forces.
  • a web 29 'connected strip-shaped leaf springs 29 are attached, which extend under the tread plate 12 and engage in slots 32 of the projection 25 such that between the Foot plate 12 and the leaf springs 29 there is a positive connection.
  • the leaf springs 29 are bent somewhat downward in a hook-like manner, so that they can also hold the tread plate 12 in the longitudinal direction of the ski. The web 29 'serves this purpose.
  • the arrangement and design of the leaf springs 29 are such that the leaf springs 29, when the base plate 16 is mounted according to FIG. 1, exert a spring force directed downwards towards the ski 15 onto the tread plate 12, so that these are by means of their inclined surfaces 20, 20 'on the inclined surfaces 19th , 19 'of the base plate 11 is pressed.
  • the slot 39 and the hook-shaped projection 40 guided therein prevent the tread plate 12 from lifting off in the rear region.
  • the base plate 16 and the tread plate 12 are put together in that the hook-shaped ends 44 of the leaf springs 29 are inserted into the slots 32 from the front in the case of plates 12, 16 which are tilted slightly downwards relative to one another. If the base plate 16 is then fastened to the ski 15 by the screws 33, the plates 12, 16 come into alignment with one another and the hook-shaped ends 44 reach down over the sloping surface 20 'bearing web 25' of the projection 25, so that the tread plate 12 is fixed on the base plate 16 in the longitudinal direction of the ski and is pressed by the leaf springs 29 onto the base plate 11 arranged underneath, which in turn slides in the longitudinal direction of the ski on the surface of the ski 15. over the inclined surfaces 19, 20; 19 ', 20', the control surfaces 13, 14 are pressed against each other.
  • the control slide 21 in FIG. 2 is either shifted upward (right) or downward (left).
  • the control surfaces 13, 14 slide relative to one another, which because of the inclination of these surfaces has the consequence that the base plate 11 is either moved forward or backward on the ski 15. If the control surface 13 moves downward in FIG. 2, the base plate 11 is shifted to the right, if the control surface 13 moves upward in FIG. 2, the base plate 11 shifts to the left, because of the leaf springs 29 on the tread plate 12 and the inclined surfaces 19, 20 and 19 ', 20' spring force exerted by the inclined surfaces in the longitudinal direction of the ski to the rear.
  • the inclined surfaces 19, 20 and 19 ', 20' shift in skis longitudinal direction relative to each other, which then results in a corresponding height adjustment of the tread plate 12 after the base plate 11 assumes a fixed position in the vertical direction due to the sliding contact on the ski surface.
  • the tread plate 12 and thus the sliding insert 38 can thus be adjusted to such an altitude that the sole 35 of the ski boot 36 inserted into the binding just comes into the desired positive but not clamping engagement with the sole hold-down 27.
  • the overlap area of the control surfaces 13, 14 in the direction perpendicular to the ski surface is sufficiently large so that the control surfaces 13, 14 are still in engagement with each other over a considerable part of their total surface at each height adjustment.
  • the force of the leaf spring 29 is to be selected so that the control surfaces 13, 14 are pressed into firm engagement with one another, but the engagement must not be so strong that the adjustability is made too difficult by turning the threaded rod 31. Most conveniently, the force of the spring 29 is just so strong that the control surfaces 13, 14 engage securely, but excessive frictional forces are avoided.
  • the maximum height h (Fig. 1) of the inclined surfaces 20, 20 'above the base 10, from which they originate, is preferably 4 to 6 and in particular about 5 mm. This results in a height adjustment range of the tread plate 12 of approximately 3 to 5, in particular approximately 4 mm, which is sufficient for all practical needs.
  • the falling of the inclined surfaces 19, 19 'and 20, 20' seen from the front jaw 28 to the rear has the further advantage that the rear surface 9 of the tread plate 12 can be formed sloping downwards towards the ski surface, since it is practically parallel to Inclined surface 20 runs. In this way, the tread plate 12 - seen from the rear - rises like a wedge starting from the ski surface, which makes it easier to slide on a ski boot inserted into the binding from behind.
