Definitions

  • the invention relates to a cross-country ski binding with the features according to the preamble of claim 1.
  • a known cross-country ski binding of the type DE-A No. 2643223 described above has a holder which essentially consists of a strap which encompasses and overlaps the front end of a sole extension of the cross-country ski boot and a locking element which overlaps the strap.
  • the locking element is a clip or clasp, which has a hook element at its rear end, with which it engages behind both the rear edge of the bracket and a rear-facing shoulder of the sole extension in the tensioned position.
  • a guide roller is mounted on each of its two longitudinal sides, which can roll on an associated guide curve in such a way that the clip can be moved up and down about the hook element as a pivot point.
  • the guide curve has two locking recesses into which the guide roller is drawn in by a tension spring acting on the clamp and of which the upper determines the release position and the lower the clamping position of the clamp. In the tensioned position, the hook element of the clip is held behind and under the rear edge of the bracket, which is bent upwards at an angle.
  • the well-known cross-country ski binding consists of a plurality of individual parts and is therefore complex to manufacture and assemble, which has an impact on the price.
  • these individual parts e.g. the guide rollers on the guide curve or the tension spring acting on the clamp
  • the interaction of these individual parts will be impaired by snow or dirt entering during use, so that the function is disturbed.
  • the invention is therefore based on the object of creating a cross-country ski binding of this type which is of simpler construction and is less susceptible to malfunctions.
  • the cross-country ski binding according to the invention consists in the specified embodiment only of two parts, namely the bracket having the bracket and the clip.
  • the clip consists of a solid, but flexible, deformable material, e.g. As polyamide or polyurethane, the elastic bending deformability is sufficient to snap the clip onto the holder, taking advantage of the guiding action of the said guiding surface, so that the hook element traces the rear edge of the bracket and the front surface of the recess, to which the guiding surface leads , grasp the mentioned edge parallel to the rear edge of the frame.
  • the forwardly extending bracket extension is supported on the top of the ski, for. B.
  • the clip By lifting the clip extension, the clip can be brought back into a release position, the clip pivoting essentially around the point of contact of the rear edge of the bracket on the inner surface of the hook element and the front inner surface of the recess sliding along the aforementioned front edge with simultaneous elastic bending of the clip, until she releases the edge.
  • the bracket thus combines holding, guiding and locking function due to the described design.
  • the edge in front of the rear edge of the frame, which comes into contact with the recess in the tensioned position, is expediently the front edge of the frame, so that the width of the frame is the measure determining the distance between the hook element and the guide surface.
  • the holder has side walls which extend forward on both sides of the bracket and to which the clip is movably fastened.
  • this attachment does not have to take on any significant weight, but only serves to prevent undesired loosening of the clip from the holder in the release position. It is therefore possible to design the clip and the side walls in such a way that they can be fitted into one another in the manner of an elastic snap connection and can be easily detached from one another. This also enables the clip to be replaced if necessary.
  • the ski binding according to the invention also provides the function of a safety binding, ie an automatic release of the clip from the holder in the event of excessive lifting and bending of the foot forward.
  • a safety binding ie an automatic release of the clip from the holder in the event of excessive lifting and bending of the foot forward.
  • a lever surface projecting backwards is provided on the hook element, which remains out of contact with the upper side of the sole extension of the cross-country ski boot during normal use.
  • the top of the sole extension comes into contact with the lever surface and thereby creates a torque on the bracket in the direction of triggering the hook element from the fin reached with the rear edge of the bracket.
  • Skibin extension consists of only two relatively movable parts, namely a mountable on the top 1 of a ski bracket 2 and a bracket 2 attached to the bracket 3.
  • the existing metal or plastic Bracket 2 has an essentially rectangular base plate 21, from the two longitudinal sides of which vertical side walls 22 project upward, which form legs 23 which diverging from one another in their rear region. Between their front and rear ends, the side walls 22 are connected in a bridge-like manner by a bracket 24, the rear edge 25 and the front edge 26 of which are rounded (FIG. 2). The height and also the thickness of the side walls 22 increase from the bracket 25 to the front (FIGS.
  • the bracket 3 consists of a hard, but elastically bend-deformable plastic, for. B. made of polyamide or polyurethane, and is formed at its rear end to a hook element 31 which is at a distance forward, which is less than the width of the bracket 24, a guide surface 32 opposite.
  • the guide surface 32 forms the front lower boundary surface of a transverse one. in cross-section approximately tailellip table recess 33, which extends from the guide surface 32 and from the tip of the hook element 31 to the inside. Due to the described cross-sectional design of the recess 33, the clamp 3 in the area 34 in front of the hook element 31 has a thinner wall thickness, which results in an elastic bendability of the clip in this area.
  • a clip extension 36 extends in an arc towards the front and is supported in the tensioning triangle shown in FIG. 1 via a support surface 37 on the ski upper surface.
  • the support surface 37 is from the head a set screw 38 is formed, which is screwed by means of a self-threading into the bracket extension 36 and therefore cannot rotate automatically.
  • the set screw 38 protrudes slightly with its knurled circumferential surface over the tapered surface of the clamp extension 36 (see FIGS. 4, 5).
  • Between the middle part 35 and the screw 38 of the bracket extension forms one of the two sides he l to gCode opening 39 into which the skier can engage with the stick or the fingers, to pull the clip projection 36 upward for the purpose of the solution.
  • Fig. 6 shows the position of the clamp 3 immediately before pressing on the bracket 24.
  • a rear-facing shoulder 4 of the thickened end area of a front sole extension 5 of a cross-country ski boot 6 in the holder 2 After inserting the end area 6 moves the bracket 3 into the position shown in FIG. 6, in which the tip of the hook element 31 just engages under the rear edge 25 of the bracket.
  • the guide surface 32 is in contact with the upper side of the bracket 24, ie without the application of force in An engagement of the recess 33 in the bracket 24 cannot be produced in the direction of the arrow 7.
  • a lever surface 43 extends to the rear, which also projects considerably beyond the rear edge 25 of the bracket 24 in the tensioned position (FIG. 1). Is it z. B. if the skier falls forward to a contact between the top of the sole extension 5 and this lever surface 43 and a forward and upward force is exerted on the lever surface 43, this force creates a torque about an axis which lies in the support surface 37 and extends transversely to the ski. Due to this force and due to the inclined course of the inner surface of the recess 33 adjoining the hook tip, the clamp 3 is bent up elastically, which leads to a release of the recess 33 from the bracket 24. After the solution, the clamp 3 assumes the position shown in FIG. 7 and thereby releases the sole extension 5.
