Definitions

  • the invention relates to a front sole holding device on a ski binding, as specified in the preamble of claim 1 in detail.
  • a sole holding device of this type is known from DE 40 07 667 C1.
  • the tread plate can be pivoted about an axis mounted at a distance from the ski surface, which at the same time forms a pivot bearing for a U-shaped bracket, which is part of the tensioning device.
  • the tension pressure that is supposed to hold the ski boot on the step plate therefore acts directly and without any reinforcement on its swivel axis.
  • the clamping pressure that can be achieved in this way is relatively small and, in practice, cannot ensure that the ski boot is securely clamped on the tread plate with a pure frictional connection between the latter and the ski boot sole.
  • a positive connection between the ski boot and the tread plate is therefore necessary, but this requires a special shape for the underside of the ski boot sole and thus makes universal use of the known sole holding device in connection with ski boots of any design impossible.
  • the invention is therefore based on the object of designing a sole holding device of the type mentioned at the outset in such a way that it enables a very high clamping pressure to be exerted between the ski boot and the tread plate and thus also to ensure that the ski boot is securely clamped on the tread plate even with a pure friction fit.
  • the inventive design of the sole holding device with at least one pressure piece adjustable with respect to the tread plate enables a lever-like reinforcement of the clamping force achievable between the tread plate and the sole of a ski boot placed thereon and thus an increase in the frictional forces holding the ski boot on the sole holding device, so that, if desired, a positive connection between Ski boot sole and step plate can be dispensed with and work can be carried out with a pure frictional connection, which is not associated with any special requirements for boot design.
  • a front sole holding device can easily be designed in such a way that the ski equipped with it can be used both for touring and downhill skiing, and it is also easy to use crampons for ease of entry or attachment options for accessories such as touring to care.
  • the front sole holding device shown in the drawing is mounted on a ski Sk shown only in a cutout, and it serves to hold a ski boot St, which is also only partially shown, and which has a sole So with an edge Ra protruding in the front toe region.
  • the support for the ski boot St on the sole holding device shown in the position for touring is a step plate 1, on which the ski boot St is placed with the front area of its sole So.
  • This tread plate 1 is on the ski (Sk) by a cross to it Longitudinal axis and parallel to its surface first pivot axis 2 pivotally mounted, which in turn is held at a distance therefrom by means of a bearing plate 3 on the surface of the ski Sk.
  • the tread plate 1 is shown in its lower end position assigned to the touring run as the starting position. From this first end position, the step plate 1 can be pivoted to a limited extent around the pivot axis 2 upwards after the touring run, and further after the ski boot St has been removed, into a second end position assigned to the downhill run.
  • two clamping jaws 4 are articulated on both sides of the step plate 1 about a second pivot axis 5 parallel to the pivot axis 2 for the step plate 1, which jaws protrude upward above the surface of the step plate 1 and onto a system on the underside of the sole So the ski boot St or as in the case shown are set to engage in a recess therein.
  • such pressure pieces on the tread plate 1 can also be pivoted about pivot axes which do not run parallel to the pivot axis 2 for the tread plate 1 itself, but enclose an angle therewith, the pressure pieces then bearing against the sole so much more or less from both sides.
  • a clamping device For pressing the clamping jaws 4 on the sole So of the ski boot St, a clamping device is used which, in the example shown, has a clamping bracket 6 of approximate U-shape and one on the clamping arm 6 articulated with a third pivot axis 7 parallel to the pivot axes 2 and 5 Transverse web of this clamp 6 foldable two-armed tensioner lever 12 has.
  • this tension lever 12 presses on the from above protruding front edge Ra of the sole So of the ski boot St and this thus against the clamping jaws 4, which in turn are pressed by the clamping bracket 6 simultaneously with pivoting about its pivot axis 5 on the tread plate 1 against the underside of the sole So of the ski boot St.
  • a correspondingly mounted tensioning rope can also be provided as a carrier for the tensioning lever 12, with it being advantageous in both cases to make the tensioning element, i.e. the tensioning bracket 6 or the tensioning rope, adjustable in length, in order to be able to adapt to different ski boot dimensions and in particular sole thicknesses.
  • the multi-joint connection between the tensioning lever 12 on the one hand and the clamping jaws 4 on the other hand results in an increase in the tensioning force emanating from the tensioning lever 12 on the ski boot St in the manner of a toggle joint closure, so that the sole So of the ski boot St is so tight between the top of its protruding edge Ra Pressing lower end of the tension lever 12 on the one hand and the clamping jaws 4 resting on the underside of the underside on the other hand is clamped in that a secure holding of the ski boot St on the tread plate 1 is also guaranteed if instead of the positive connection shown in the drawing between the sole So of Ski boot St and the clamping jaws 4 only a pure frictional engagement is provided, so the clamping jaws 4 only rest against the sole So of the ski boot St which then has no recess.
  • the upper side of the clamping jaws 4 facing the sole So of the ski boot St has an adhesion-increasing surface formation, for example in the form of a corrugation 11, as is provided in the example shown.
  • tensioning device shown in the drawing with the tensioning bracket 6 which can be pivoted about the horizontal pivot axis 7 and the tensioning lever 12 mounted thereon represents only one, albeit preferred, possibility.
  • a tensioning device can also be provided which extends the front end of the ski boot St with the protruding edge Ra from the front, and when it closes in the manner of a folding lever lock except for a pressure on the ski boots St, a pull on the Jaws 4 exerts and this can pivot about its pivot axis 5 upwards into contact with the sole of the ski boot St.
  • an angled stop 9 is provided on the upper side thereof, which facilitates the correct placement of the ski boot St on the step plate 1.
  • the position of the step plate 1 selected for the representation in FIG. 1 is assigned to touring, in which the ski boot St can be pivoted upwards about the pivot axis 2 together with the step plate 1.
  • the front sole holding device shown, however, in conjunction with a rear boot holder (not shown in the drawing) also enables a firm connection of the ski boot St to the ski sk that is suitable for downhill skiing. For this purpose, as shown in FIG.
  • a is on the underside of the step plate 1
  • Sole holder 8 is provided, which, after swiveling up the tread plate 1 about the swivel axis 2 into the vertical, can be unfolded from its rest position into a horizontally directed working position and then the protruding edge Ra of the sole So of the ski boot St placed directly on the surface of the ski Sk overlap at the top and front so that the tip of the ski boot can hold onto the ski sk.
  • a recess 10 is provided in the front area of the tread plate 1 on both sides of its longitudinal axis, which allows a crampon to be hung along the pivot axis 2.
  • the invention can be described as a front sole holding device on a ski binding for a ski boot that has a sole that protrudes in the front toe region.
  • This sole holding device has a step plate for supporting the ski boot from below, which is mounted on the ski so as to be pivotable between two end positions about a first pivot axis running transversely to its longitudinal axis and parallel to its surface.
  • an adjustable tensioning device is provided for exerting a tensioning pressure on the ski boot placed on the step plate for holding it on the step plate.
  • At least one pressure piece that is designed for frictional and / or positive engagement on the sole of the ski boot, in particular in the manner of a toggle lever, is articulated and in this way with coupled to the tensioning device that this seeks to bring the pressure piece into contact with the sole of the ski boot simultaneously with the application of the tensioning pressure.
