Definitions

  • the sole holder is secured to a pivoted lever, which is pivoted on a transverse pivot, which is fixed relative to the ski.
  • the pivoted lever is slidably mounted on -the transverse pivot by a guide slot.
  • a spring force in a forwardly and downwardly inclined direction acts between the pivoted lever and the ski.
  • the sole holder is mounted on -the pivoted lever for an upward pivotal movement.
  • a detent device which is disengaged in response to an excessive tension is provided between the sole holder and the pivoted lever.
  • Heel-releasing devices for safety ski bindings so-called step-in bindings, are known, in which devices the sole holder is secured to a longer pivoted lever, which has a detent socket engaged by a spring loaded detent pin.
  • this known heel-releasing device has the disadvantage that the foot is very rigidly secured .to the ski so that fatigue is soon experienced.
  • the known heel-releasing device does not force the foot forwardly against the toe iron of the ski binding and at the same time downwardly against the ski.
  • a heel-releasing device for safety ski bindings in which device the sole holder is secured to a pivoted lever, which is pivoted on a transverse pivot, which is fixed relative to the ski, these disadvantages are avoided ⁇ according to the invention in that the pivoted lever is slidably mounted on the transverse pivot by a guide slot, a spring force in a forwardly and downwardly inclined direction acts between the pivoted lever and the ski, the sole holder is mounted on the pivoted lever for an upward pivotal movement, and a detent device which is disengaged in response to an excessive tension is provided between the sole holder and Ithe pivoted lever.
  • the slidable mounting of the pivoted lever on the transverse pivot and the spring force in a forwardly and downwardly inclined direction ensure that the heel-releasing device resiliently urges the foot forwardly against the toe iron.
  • the spring acting in a forward and downward direction ensures at the same time that the foot can lift from the ski within certain limits against the force of the spring and can carry the pivoted lever and the sole holder along in this movement so that the above-mentioned fatigue is avoided.
  • a bolt is pivoted to a base plate, which is fixed to the ski, said bolt extends through an oversize opening in the pivoted lever and a coiled compression spring bears at one end of a spring abutment plate at the free end of the bolt and at the other end on the pivoted lever so that the spring force acting in a forward and downward direction is produced.
  • the detent device between the pivoted lever and the sole holder may comprise a detent lever, which is pivoted to the pivoted member and bears by the release spring on the pivoted lever and is provided at its free end with an actuating means for an arbitrary opening of the heelreleasing device.
  • FIG. 1 is a vertical longitudinal sectional view show- Y ing a heel-releasing device according to the invention and FIG. 2 is a side elevation showing the releasing device of FIG. 1 in the released position.
  • a base plate 3 is secured by screws 2 to a ski 1 and has on its sides two upright lugs 5.
  • a pin 6 extending transversely to the longitudinal direction of the ski is mounted in the two lugs.
  • a pivoted lever 7 is mounted on the pin 6. The pin is received by a slot 8 of the pivoted lever 7 so that the latter is displaceable in the longitudinal direction of the ski.
  • a bolt 9 is pivotally suspended between the two fixing lugs 5.
  • the bolt 9 has a ⁇ bearing eye, which receives the pin 10. At its free end, the bol-t 9 is provided with screw threads.
  • the bolt 9 extends through an oversize opening 11 of the pivoted lever 7 and is threaded into an adjustable spring abutment plate 12.
  • a spring 13 bears at one end on the spring abutment plate 12 and at the other end on the pivoted lever 7. Owing to the inclina-tion of the bolt 9 and of the spring 13, the pivoted lever is resiliently urged in a downward direction and pushed forwardly toward the tip of the ski.
  • a sole holder 14 is pivoted to the pivoted lever 7 with two lugs 15, which embrace the pivoted lever 7 and are connected to it by the pin 16.
  • a detent device is provided between the sole holder 14 and the pivoted lever 7.
  • the detent device consists of a detent lever 4, lwhich is pivoted by a pin 18 in an aperture 17 of the pivoted lever 7. Under the action of :the release spring 19, the detent lever 4 is urged against the sole holder.
  • the detent lever 4 has a nose 20, which engages a mating detent recess 21 of the sole holder. To enable an arbitrary opening of the binding, the detent lever 4 is prolonged and provided with a conical recess 22.
  • the ski stick is inserted into the recess 22 and used to depress the lever 4 against the force of the spring 19 so that the nose is disengaged from the recess 21.
  • the heel can now be lifted so that the sole holder is pivotally moved relative to the pivoted lever 7 and releases the heel.
  • the sole holder 14 has a step-in pedal 23, which is engaged by the heel as it steps into the binding so that the sole holder is depressed until the nose 20 snaps back into the recess 21.
  • the sole holder is provided at its forward end with teeth 24, against which a retaining member 25 is forced, which is formed with mating teeth.
  • the connection lbetween the retaining member 25 and the sole holder In response to excessive forces at right angles to the surface of the ski, the pivoted lever 7 will perform a predetermined upward pivotal movement about the pin 6 against the action of the spring 13.
  • the sole holder which is held by the detent on the pivoted lever, will follow the movement of the latter.
  • the detent device When the force reaches the value to which the detent has been preset by an adjustment of a predetermined initial stress of the spring 19, the detent device will be released to permit of a pivotal movement of the sole holder relative to the pivoted lever 3 so that the boot is freed. If the force acting at right angles to the surface of the ski is not so large, the spring 13 will return the boot to the surface of the ski.
  • a special advantage of the heel-releasing device according to the invention resides in that it can follow small upward movements of the' heel without causing a release of the foot.
  • This elastic connection between the boot and the ski precludes in a high degree of fatigue of the foot and the consequent pain on the sole of the foot.
  • Another advantage resides in that the inclined orientation of the spring 13 ensures a resilient cushioning of movements at right angles to the ski as well as a forward pressure on the foot.
  • the sole holder can perform a large pivotal movement relative to the pivoted lever upon a release so that the boot is entirely freed and the heel does not merely slip out of the sole holder, as is the case with many known bindings. The latter operation may cause damage to the heel after prolonged use.
  • the release spring may be relatively weak so that a small opening work performed on the detent lever will be suhicient when the user desires to step out of the binding.
  • the arrangement of the interengaging surfaces and of the pivotal axes of the detent lever and sole holder may be selected so that the detent will not be released unless relatively large forces are effective.
  • Heel release device for safety ski binding comprising a lever pivotally mounted to a ski about a pivot axis extending transversely to the ski, a sole holder pivoted to said lever, spring means biasing said lever to counteract upward and rearward movement thereof, said lever delining a slot extending normal to and through which said pivot axis passes to enable movement of said lever in a fore and aft direction with reference to the ski, detent means releasably holding said sole holder and said lever rigidly engaged under normal operating conditions and upon the occurrence of an excessively high pulling force releasing to enable said sole holder to pivot relative to said lever.
  • said detent means includes a detent lever pivoted at one end to said pivoted member which is resiliently urged by a spring to a forward position at which it engages with said sole holder, said lever provided at its free end with an actuating means to effect an arbitrary opening of the heel release device.
  • a heel-releasing device characterized in that a bolt is pivoted to a base plate, which is fixed to the ski, said bolt extends through an oversize opening in the pivoted lever and a coiled compression spring bears at one end on a spring abutment plate at the free end of the bolt and at the other end on the pivoted lever so that the spring force counteracting upward and rearward movement is produced.
