Definitions

  • the present invention relates to cross-country ski bindings for cross-country ski shoes with an extended front sole end which is designed as a downward hook and has a cross-piece which is intended to cooperate with the sole end and which is mounted in side jaws which extend upward from a base plate which is to be mounted in a ski-tight manner.
  • cross-country ski bindings are already known from DE-A-2829564. Compared to well-known cross-country ski bindings, they offer the advantage of a particularly simple and failure-resistant construction, since neither the bending of the forward sole end nor part of the ski binding is necessary when the ski boot is lifted off the ski.
  • the traverse is part of a curved wire bracket, which at the same time serves to secure the connection of the ski boot to the ski binding.
  • a special locking cam is required on the forward end of the sole.
  • the wire bracket also extends upwards away from the ski surface when in use.
  • a swiveling of the ski boot on the crossmember upwards against an initially low and then progressively increasing resistance is not provided in these known cross-country ski bindings.
  • the present invention aims at designing the generic cross-country ski binding in such a way that the described shortcomings and disadvantages are avoided.
  • a U-shaped bracket is provided in the binding for the pivotable mounting of the front sole end, the legs of which are supported at their free ends on the crossmember and the web is parallel to the crossmember, so that a front end of the sole is received Frame is formed, and that the bracket is under the influence of a spring that loads it in the sense of pinching the front sole end and against whose resistance the shoe can be pivoted upward about the crossmember.
  • a first embodiment has proven to be expedient, in which the bracket is designed as a crank arm and is connected via an axle pin to a thrust member which is longitudinally displaceable and pivotable relative to the base plate.
  • a particularly simple construction is achieved in that the thrust member is supported on the base plate with a cam and is held in its inner limit position under the influence of a spring, and in that the spring is designed as a spiral spiral spring and is mounted on the journal.
  • the spring has a double function in this case, by loading the pushing element on the one hand and the bracket on the other hand.
  • a locking lever is provided on the thrust member in a constructive embodiment of the invention, which has a locking hook.
  • the base plate has a barb intended for cooperation with the locking hook and the locking lever is loaded by a retaining spring in the sense of unlocking.
  • This construction allows an arbitrary hooking of the locking lever on the base plate, whereby the ski binding is given a fixed open position. After the boot has been inserted into the ski binding, it must be lifted in the direction 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 boot is pivoted further, the locking lever is hooked to the base plate automatically when the boot is moved is released and the cross-country ski binding is in its working condition.
  • An embodiment of the cross-country ski binding according to the invention in which a thrust member which is longitudinally displaceable on the base plate is avoided and which is thus even easier and more secure against wear, is achieved in that the web of the stirrup is provided with a depression which extends in the longitudinal direction of the ski and is opposite the crossbar and that a locking lever is provided for interacting with the bracket, which is mounted on an axis parallel to the crossbar in the side jaws and is loaded in the sense of unlocking by a retaining spring.
  • the spring loading the bracket is preferably designed as a tension spring and suspended on the axis of the locking lever.
  • the retaining spring can be designed as a spiral spiral spring and mounted on the axis of the locking lever. In this case, a compact and closed design can be achieved.
  • the cross-country ski binding designated in its entirety by 1 according to FIGS. 1 to 3 is fastened to a cross-country ski 3 by means of screws 2.
  • a cross-country ski boot is indicated by dash-dotted lines and labeled 4. It has a forward front sole end 5, which is designed as a downwardly open hook.
  • the ski binding comprises a base plate 6 with raised side jaws 7, in which a crossmember 8 is mounted, which serves to interact with the hook-shaped sole end 5.
  • a U-shaped bracket is mounted with its legs 10, which, when a cross-country ski boot is inserted, encompasses its front end of the sole and secures it with its web 9 against lifting off the crossmember 8.
  • the bracket forms a crank arm to which a thrust member 13 is connected via an axle pin 12.
  • This thrust member is supported by a cam 14 on the base plate 6, or rather on narrow strips of its side edges, which are formed by outlets of the side jaws 7.
  • a coiled spiral spring 11 is attached to the journal 12, one leg 15 of which is supported on the web 9 of the bracket and the other leg 16 of which is supported on the thrust member 13.
  • This thrust member also has a recess 17 on its upper side, which is used to insert the tip of the ski pole.
  • Fig. 1 shows the cross-country ski binding in its normal position. Under the influence of the spring 11, the bracket and the thrust member are held in the position shown.
  • pressure is to be exerted on the thrust member 13, for example by means of a ski pole tip in the direction of the arrow 18.
  • the bracket is pivoted on the crossmember 8 with respect to the illustration in the counterclockwise direction, so that the ski binding assumes its position shown in FIG. 3.
  • the front sole end 5 can be hooked onto the crossmember 8 when the sole position is approximately horizontal.
  • the web 9 of the bracket clamps itself on the upper side of the forward sole end 5.
  • the cross member 8 forming a real pivot axis for the cross-country ski boot.
  • the cross-country ski binding is designated in its entirety by 21. It is attached to a cross-country ski 23 by means of screws 22.
  • a cross-country ski boot indicated by dash-dotted lines is designated by 24. It has a forward front sole end 25 which is designed as a downwardly open hook.
  • the ski binding comprises a base plate 26 with raised side jaws 27, in which a cross member 28 is mounted. This serves to cooperate with the hook-shaped sole end 25.
  • a U-shaped bracket is mounted with its legs 30, which, when a cross-country ski boot is inserted, encompasses its front sole end and secures it with its web 29 against lifting off the crossmember 28.
  • the bracket forms a crank arm, to which a thrust member 33 is connected via a journal 32.
  • This thrust member is supported by a cam 34 on the base plate 26.
  • a coiled spiral spring 31 is attached to the journal 32, one leg 35 of which is supported on the web 29 of the bracket and the other leg 36 of which is supported on the thrust member 33.
  • a Riegethebet 40 is mounted on a pivot pin 44 which is parallel to the journal 32.
  • a coiled spiral spring 43 is also attached to this pivot pin, one leg 45 of which is supported on the thrust member 33 and the other leg 46 of which is supported on the locking lever 40 and loads it clockwise with respect to the figures.
  • the locking lever has a locking hook 41, which serves to interact with a barb 42 on the base plate 26.
  • the locking lever also has a recess 47 on its upper side, which is used to insert the tip of the ski pole.
  • the cross-country ski binding according to the invention is shown in its normal position.
  • the front sole end 25 is secured on the cross member 28 by the web 29 of the bracket.
  • pressure is to be exerted on the locking lever 40, for example by means of a ski stick in the direction of the arrow shown.
  • This results in a displacement of the thrust member 33 with respect to the illustration to the left while pivoting the bracket until the locking lever 40 can pivot counterclockwise and can engage behind the barb 42 on the base plate with its locking hook 41.
  • the ski binding then takes off their position shown in Fig. 6.
  • the web 29 is at a distance from the top of the front sole end 25, so that the ski boot can be hooked off from the cross member 28.
  • the ski boot can be reinserted into the ski binding.
  • the ski binding can be closed by swiveling the rear end of the ski boot up by also pivoting the bracket. This is because the locking hook 41 of the locking lever 40 is released from the barb 42 of the base plate 26, and the instantaneous state according to FIG. 7 is established.
  • this construction once brought into its open position, retains it, so that the ski binding is readily ready for entry.
  • cross-country ski binding is designated 51. It is in turn fastened to a cross-country ski 53 by means of screws 52.
  • a cross-country ski boot is again indicated by dash-dotted lines and designated 54. It has a forward sole end 55 which terminates in a bead-like downwardly extending hook.
  • the binding comprises a base plate 56 with raised side jaws 57.
  • a cross member 58 is mounted in these.
  • a U-shaped bracket formed from a web 59 and two legs 60 is mounted, with the free ends of the legs.
  • the web 59 is trough-shaped, so that it can accommodate the bead-like hook on the sole end 55, as can be seen from FIGS. 8 and 11.
  • a tongue 61 formed on the web has a hole into which one end of a tension spring 62 is suspended, the other end of which is suspended on an axis 63 which is mounted parallel to the cross member 58 in the side jaws 57.
  • a locking lever 64 is mounted on this axis, which in the open position of the U-shaped bracket according to FIG. 10 can be pivoted into the movement path of its legs 60 in order to lock the bracket in the open position, and which in the sense of unlocking one Holding spring 65 is loaded, which is designed as a spiral spring and is attached to the axis 63 (see FIG. 9).
  • the locking lever On its upper side, the locking lever also has an indentation 66, which is used to insert a ski pole tip.
  • Fig. 8 shows the cross-country ski binding in its normal position.
  • the forward sole end 55 engages with the bead-like downwardly extending hook in the trough-shaped web 59 of the strap.
  • the front end of the sole is clamped between the web 59 and the cross member 58 and is thus held securely in the binding.
  • the cross member 58 forming the pivot axis.
  • the bracket is pivoted from the position according to FIG. 8 into that according to FIG. 11 against the progressively increasing resistance of the helical tension spring 62.
  • the locking lever 64 To move the ski binding from the normal position according to FIG. 8 into its open position, the locking lever 64 must be pressed down, for example by means of a ski stick, against the force of its retaining spring 65, that is to say pivoted clockwise about the axis 63 in relation to the illustration. Angled side parts 67 of the locking lever each run against one leg 60 of the bracket, so that it is pivoted from its position in FIG. 8 into that in FIG. 10 about the cross member 58. This pivoting causes the clamping connection of the sole end 55 to be released from the crossmember, so that the shoe can be removed from the binding by lifting the front sole end from the web 59.
