Definitions

  • the invention relates to a cross-country ski binding for cross-country ski shoes, which have corresponding engagement elements insertable at their front sole end into engagement elements of the ski binding for producing an articulated connection, with a U-shaped bracket for securing the front sole end against lifting off the ski binding-side engagement elements, the legs of which with their free Ends on ski-fixed side jaws of the ski binding are pivotally mounted about a transverse axis and which is loaded by a spring in the direction of a position overlapping the front sole end with its web, and with a spring-loaded locking lever which engages behind a locking projection of the ski binding by means of a locking hook and thereby the U-shaped bracket can hold in an open position.
  • the U-shaped bracket can be hooked onto the base plate of the ski binding arbitrarily by means of the locking lever, as a result of which the ski binding can assume a fixed open position. This makes it easier to insert the ski boot into the ski binding.
  • the strap is in its overlapping and the front sole end
  • ski boot is fixed in the ski binding position in that after inserting the ski boot this is raised in the sense of a running movement until the top of the front sole end comes into contact with the web of the strap, after which when the ski boot is pivoted further by carrying the bracket the hooking of the locking lever on the base plate is released automatically.
  • the cross-country ski binding is thus in its use state.
  • the present invention aims to improve this cross-country ski binding in that it is designed as a step-in binding, i.e. the state of use of the ski binding is already brought about by the insertion process of the ski boot into the ski binding itself and not only by a subsequent lifting of the ski boot in the sense of a running movement.
  • the locking lever can be brought into engagement with the locking projection in the sense of fixing the open position by pressing the locking lever down with the ski pole, for example, and then lowering the ski boot when the ski boot is raised.
  • the locking hook of the locking lever engages in the course of a backward movement of the locking projection and prevents the bracket from moving back, so that it remains in the open position and the ski boot can be lifted out of the ski binding.
  • the front sole end presses on the cam element located in the movement path of the sole end in this state, which in turn acts mechanically on the locking lever, i.e. lifts it out of engagement with the locking projection.
  • the spring acting on the strap becomes effective and moves the strap into the position overlapping the front sole end.
  • the locking lever is pivotally mounted on the bracket and acted upon by a leg spring in the direction of an unlocking position.
  • this design enables the cam element to be arranged directly and expediently in one piece on the locking lever itself.
  • the locking lever can also be rigidly attached to the bracket and be designed to be flexible in the manner of a leaf spring.
  • the cam element is mounted separately on the ski binding and, when actuated, pushes the locking hook of the locking lever as described out of engagement with the locking projection, so that the locking lever moves under the inherent bending elasticity in the direction of the unlocking position.
  • laterally projecting pins are provided as ski-element engagement elements on the front sole end, which can be inserted into upwardly open bearing recesses in the legs of the bracket.
  • the long louse ski binding shown comprises a base plate 1 with a cross bar 2 and side jaws 3 which are arranged in one piece at the front end thereof.
  • the base plate is fastened on a ski 5 by means of screws 4.
  • a cross member 7 Extending between the side jaws 3 is a cross member 7, on which a U-shaped bracket 8 is pivotally mounted in the end region of its free legs.
  • the U-shaped bracket 8 has a web 9 which, in a manner described in more detail below, in the use state of the ski binding according to FIG.
  • the legs 10 of the bracket 8 have in their edges upwardly open bearing recesses 11 which serve to receive laterally projecting circular cylindrical pins 12 of the front sole end.
  • a locking lever 15 is pivotally mounted on a crossmember 14, which carries a locking hook 16 (FIG. 3) at its front end. From the base plate 1, a locking projection 17 protrudes upward, which has a slightly protruding bead 18 at its upper end.
  • the locking lever 15 is acted upon by a light torsion spring, not shown, in the direction of the unlocking position shown in FIG. 1.
  • a slide 20 is also pivotally mounted, which has a recess 21 for the locking lever 15.
  • the slide 20 lies in the region of its front edge on the cross bar 2 and has a thickening 22 in the region of its rear edge with which it is mounted on the cross member 14, which carries an internal thread.
  • a guide pin 24 for a helical compression spring 25 is screwed into this internal thread and has a collar 26 at a certain distance in front of its rear end as a support for the helical compression spring 25.
  • the helical compression spring 25 is supported with its front end on the inside of the cross bar 2.
  • the guide pin 24 has a screw slot 27 so that it can be screwed more or less far into the nut-like thickening 22 by means of a screwdriver and the prestress of the helical compression spring 25 can thereby be changed.
  • the helical compression spring 25 seeks to pivot the U-shaped bracket 8 clockwise into the use position, so that the web 9 is pressed firmly onto the top of the front sole end when the ski boot is inserted.
  • the cross bar 2 has a bore through which the guide pin 24 can pass.
  • the locking lever 15 In the thickened region of the locking lever 15, in which this is traversed by the crossmember 14, the locking lever 15 carries a rearwardly projecting cam element 30 which, in the open position of the ski binding shown in FIG. 3, protrudes into the movement path of the front sole end when the latter with the laterally protruding pin 12 is inserted into the bearing recesses 11.
  • the U-shaped bracket In the open position of the ski binding shown in FIG. 3, the U-shaped bracket is held in its open position by the locking lever 15.
  • the locking lever 15 engages behind the locking protrusion 17 with the locking hook 16, the bead 18 resting in a corresponding recess in the locking hook 16.
  • the force of the spring 25 is absorbed by the locking projection 17 in this state.
  • the front sole end of the ski boot with the pin 12 can be inserted into the bearing recesses 11 from above at the rear, the rear edge of the bending joint 10 running towards the position recesses 11 serving as a guide surface as soon as the pin 12 sinks into the bearing recesses 11 , presses the front end of the sole onto the cam element 30, so that the locking lever 15 is loaded clockwise and the locking hook 16 is lifted out of engagement with the locking projection 17.
  • the bracket 8 is again under the force of the helical compression spring 25, which the bracket in Turned clockwise backwards into the position shown in Fig. 1.
  • the locking lever 15 must be pressed down, for example by means of the ski pole, against the low force of the torsion spring while the ski boot is in the raised position according to FIG. 4 and thus the locking hook 16 the locking lever 15 lies in front of the locking projection 17. If the ski boot is now lowered, the locking hook 16 comes into engagement with the locking projection 17 and blocks the bracket 8 in the open position according to FIG. 3. In this open position, the pins 12 can be lifted up out of the bearing recesses 11 again.
  • the slide 20 rests on the edges of the side jaws 3 sloping towards the front and slides thereon and on the upper edge of the cross bar 2 during the up and down movement of the ski boot during use.
  • the slide has the task of protecting the interior space delimited by the side jaws 3 and the cross bar 2 from the ingress of snow.
  • the locking lever 15 can also be mounted directly on the slider 20 instead of the bracket 8 or the cross member 14, and instead of only one helical compression spring 25 two or more of them can be used, which are based on corresponding thickening of the slider or directly on the cross member 14 or Press bracket 8. If several compression springs 25 are selected, they can also have different spring stiffness and can be used interchangeably in the housing formed by the cross bar 2 and the side jaws 3. In this case, it is possible to dispense with an adjustment option for the compression springs, as is provided by the guide pin 24 in the exemplary embodiment shown, because the spring force can be determined by the choice of the appropriate number and / or correspondingly stiff designs of the compression springs.
