Definitions

  • the invention relates to a safety ski binding according to the preamble of claim 1.
  • Such a safety ski binding is described, for example, in WO82 / 02495 (see Fig. 14, 15).
  • the sole holders are designed as angle pieces which can be swiveled by a vertical axis, one leg of which holds the sole of the ski boot, while an angle lever is articulated on the other leg.
  • the ends of the angle lever directed towards one another are connected to one another in an articulated manner and acted upon by a leg spring in the closing direction of the ski binding.
  • the free ends of the angle levers are directed towards the front.
  • the base plate is deflected, the free end of an angle lever touches an ⁇ ki-fixed stop, which causes the angle lever and the sole holder to pivot.
  • This known ski binding has the disadvantage that the front jaw consists of many individual parts which are movable relative to one another. As a result, friction forces that are difficult to control can occur at many points, and the production of a ski binding consisting of so many individual parts is also complex.
  • a return spring which is separate from the release spring which is attached in the heel holder and controls the plate movement is required for the return of the locking elements and the sole holder after a safety release.
  • this known ski binding in the event of a ski deflection due to uneven terrain, only a slight longitudinal compensation is possible before jamming occurs.
  • the aim of the present invention is to avoid the disadvantages mentioned and to make the structure of a ski binding of the type mentioned initially more compact and to reduce the number of individual components. Furthermore, tension in the sole of the ski boot or jamming of binding parts in the event of ski deflection are to be reliably avoided.
  • the stated object is achieved according to the invention by the characterizing features of claim 1.
  • the fact that the locking and the control element is pivotally mounted on an axis arranged centrally between the sole holder bolts on the sole plate means that the ski binding has a compact construction small number of components.
  • the arrangement of the rod-shaped control element in a free position of the longitudinally displaceable housing reliably prevents tensioning of the ski boot sole or jamming of the binding base plate.
  • a housing which is displaceable in the longitudinal direction of the ski is known per se from AT-PS 384.950.
  • the embodiment according to the features of claim 2 enables a common movement of the locking element with the control element.
  • the measure of claim 3 saves the use of additional components.
  • the measure of claim 4 makes it easier for the binding fitter to assemble or adjust the length of the ski binding without time-consuming manipulations.
  • the features of claim 5 ensure that the ski binding automatically returns to the entry-ready position after a safety release.
  • the upper horizontal region of a carrier element essentially extends over the width of a front end region of the soleplate.
  • the embodiment according to the characterizing part of the award to ⁇ 8 allows the designer Ausschwenkddling Aus ⁇ chwenk Scheme and of the sole holder to make optional.
  • FIG. 1 shows the ski binding according to the invention in longitudinal section
  • FIG. 2 shows the front jaws according to FIG. 1 on a larger scale
  • FIG. 3 shows a top view thereof, partially cut along the line III-III of FIG. 2
  • FIG. 4 shows the front jaws with the sole plate partially pivoted
  • FIG. 5 the front jaw at the release point, partially cut along the line VV of FIG. 2,
  • FIG. 6 the front jaw when released
  • FIG. 7 the front jaw during the return movement.
  • front, rear, left and right refer to the position of the ski binding, i.e. front means towards the ski tip etc.
  • FIG. 1 A complete safety ski binding to be described in more detail below can be seen in FIG.
  • the parts shown with dash-dotted lines are not the subject of the invention and have only been shown for the sake of clarity.
  • a base plate 3 for a toe 10 and a mounting plate 5 for a sole plate 20 pivotably mounted on a pivot 6 in a known manner are fastened on a ski 1 by means of screws 2, which are only partially indicated.
  • the sole plate 20 also carries a heel holder 30 and a ski brake 40, the known type are not part of the invention and are therefore not described in detail.
  • the toe 10 according to the invention is shown in the driving position of the ski binding.
  • the base plate 3 has on both sides extending in the ski longitudinal direction, upwardly projecting guide rails 3a.
  • a housing 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.
  • an exemption 4b is provided for parts of the toe piece 10 to be described later.
  • the exemption 4b has stops 4c on its lateral edges.
  • a path limitation 4f which lies in a plane running transversely to the ski longitudinal direction and normal to the top of the ski and which together with the head of the screw 2 ensures the correct positioning of the housing 4 relative to the base plate 3 enabled the length of the ski binding.
  • a guide groove 4h is cut out on the side facing the relief 4b.
  • the guide groove 4h runs along a circular ring piece, the center line of which is drawn along a circle, the center point of which lies in the axis of the pivot pin 6.
  • 4 through holes 4i for the screws 2 are provided in the housing.
  • a transverse inner wall 4j of the relief 4b is laterally provided with a control curve 4d.
  • a front end region 20a of the sole plate 20 is designed as a bearing for the sole holder 7 and a trigger mechanism to be described in more detail.
  • the sole plate 20 has straps 20b extending forward at its front end region 20a.
  • a vertical section 20c extends in the middle width region of the front end region 20a of the sole plate 20.
  • a vertical section 20d is connected to the vertical section 20c.
  • the sole plate 20 also has guides 20e, which are not described here on both sides for a rear sole plate part, not shown.
  • a support member 20f is formed with the front end portion 20a of the sole plate 20 as a bearing unit 20g.
  • a lower horizontal region 20h of the carrier element 20f extends partly under the sole plate 20, partly in front of it.
  • a vertical region 20i which runs at least partially parallel to the vertical section 20c of the front end region 20a of the sole plate 20.
  • the vertical region 20i of the carrier element 20f has sloping contact surfaces 20n for the sole holders 7 on both sides.
  • An upper horizontal region 20j adjoining the vertical region 20i of the carrier element 20f extends essentially over the width of the front end region 20a of the soleplate 20.
  • a slot 20k is provided, in which the horizontal section 20d of the front end portion 20a of the sole plate 20 extends.
  • the upper horizontal region 20j also has an upwardly projecting projection 20m which engages with play in the guide groove 4h of the housing 4.
  • the upper horizontal region 20 is designed as a sole hold-down device 20o.
  • a vertically extending central axis 12 and two likewise vertically extending sole holder bolts 11 are anchored in the bearing unit 20g.
  • the sole holders 7 are articulated on the sole holder bolts 11.
  • the sole holders 7 are provided in their rear area in a known and therefore not described manner with contact surfaces for ski shoe soles.
  • the sole holders 7 At their front end, the sole holders 7 have downward-facing pins 7a, the function of which will be described in more detail later.
  • the sole holders 7 in their front region are curved in plan view, each curve 7b ending in a locking stop 7c.
  • a snap edge 7d is provided at the end of the curve 7b facing away from the latch stop 7c.
  • a locking element 8 and an attached pivotable together with this control element 9 ⁇ are articulated on the axis 12th
  • the locking element 8 is approximately heart-shaped in plan view and has arches 8a and converging curved surfaces 8b.
  • the control element 9 has an approximately tab-shaped design and, viewed in the driving position of the ski binding, extends from the axis 12 to the front in the region of the longitudinal axis of the ski.
  • the sole plate 20 is pivoted. It takes the locking element 8 and the control element 9 with it. As soon as the control element 9 has reached the stop 4c (see FIG. 4), it begins to pivot together with the locking element 8 about the axis 12. If the force exceeds the elasticity range of the ski binding, the sole plate 20 on the one hand and the unit consisting of the locking element 8 and the control element 9 on the other hand are pivoted further until the sole holder 7 leading in the pivoting direction, with its snap edge 7d, comes out of the area of the arch 8a of the lock ⁇ lungsisse ⁇ 8 is released (see Fig. 5) and releases the ski boot, not shown here, without further effort.
