Definitions

  • This invention relates to a toe iron for safety ski bindings, which toe iron is suitable for downhill and crosscountry skiing and comprises two soleholders, which laterally engage the skiing boot and are pivoted to a com mon pivot pin, which is held to the toe iron so as to be displaceable transversely to the longitudinal direction of the ski, a predetermined transverse displacement of the pivot pin being required to permit of a forward pivotal movement of either of the soleholders.
  • a known toe iron of this kind basically satisfies the requirement of being suitable both for downhill and cross-country skiing.
  • that known toe iron has properties which are considered highly undesirable in modern skiing.
  • the pivot pin which is displaceable transversely to the longitudinal direction of the ski is held by a detent device in its normal position.
  • any force which acts on the soleholders in a direction which is transverse or at an oblique angle to the longitudinal direction of the ski and which is less than the releasing force cannot be taken up resiliently but is opposed by a rigid resistance.
  • the detent resistance may be changed to vary the releasing force so that the latter can be individually adjusted. An arbitrary adjustment of the detent resistance, however, may result in a wrong adjustment so that the safety afforded by the toe iron is eliminated.
  • a twist- 3,490,781 Patented Jan. 20, 1970 ing fall overcome the damping resistance and positively open one soleholder so that the foot is released from the ski.
  • FIG. 1 is a side elevation showing the novel toe iron for safety ski bindings
  • FIG. 5 a sectional view taken on line VV of FIG. 2, the outer part of one carrying arm being shown in section below the soleholder.
  • the fixed toe iron part 1 is formed with a recess 10, which extends transversely to the longitudinal direction of the ski and which receives a spring element consisting of a helical compression spring 11.
  • the recess 10 is constricted at its ends to form a top ledge 12 and a bottom ledge 13.
  • the helical compression spring 11 normally bears on said ledges with parts of each of its end faces.
  • the intermediate portions of the end faces of the helical compression spring normally bears on drivers 14, 15, which are carried by the displaceable toe iron part 4 and extend in the longitudinal direction of the ski into the recess 10 and are normally disposed at the ends of the recess between the pairs of ledges 12/13.
  • the toe iron part 1 is provided with a transverse slot 16 between the recess 10 and that surface of the toe ir n part 1 which rests on the ski 3.
  • a tongue 17 of the displaceable toe iron part 4 extends into the slot 16.
  • the wall formed between the transverse slot and the ski-engaging surface of the toe iron part 1 is provided with a groove 18, which extends transversely to the longitudinal direction of the ski and which receives a guide roller 19, which is carried by the tongue 17 of the toe iron part 4. That wall of the toe iron part 1 which is disposed over the recess 10 is extended beyond the ledges 12 towards the trailing end of the ski so as to engage the toe iron part 4 from above and to form a guide bar for the same.
  • the toe portion of the skiing boot will remain gripped between the two soleholders 8, 9 because a transverse displace en of the toe iron part 4 will first cause an engagement of the backing rollers 20, 21 of the carrying arms 6, 7 with the central portion of the cam 22, which portion is transverse to the longitudinal direction of the ski (see FIG. 4).
  • a second toe iron part slidably mounted on said first toe iron part for movement transverse to the direction of the ski;
  • spring means providing a force against which said second toe iron part and pivot pin carried thereby are required to act when undergoing transverse displacement for holding said second toe iron part and pivot pin carried thereby in their normal position, and for returning said second toe iron part and pivot pin carried thereby to their normal position, after a transverse displacement, when the displacing force decreases.
