Abstract
A toe jaw for a safety ski binding having a ski boot sole hold-down mechanism which is pivotal about an axis extending generally perpendicular with respect to a base plate secured to the upper surface of a ski. A support part is provided on the hold-down mechanism and is adapted to engage the frontmost portion of the sole of the ski boot. The support part is pivotal about an axis to accommodate a movement of the ski boot away from the toe jaw upon a release of the ski boot from the ski. The spring force utilizable for returning the sole holder to the original position is the same spring force which effects a returning of the support part to the original position thereof.
Claims7
A safety ski binding, comprising:
- a binding housing mounted on the upper surface of a ski;
- symmetrically arranged, two-arm sole holders pivotal between a sole holding position and a sole releasing position about ski-fixed axes which are arranged perpendicularly with respect to said upper surface and which each rest with one arm thereof against a side edge of the sole of a ski boot and a second arm thereof against one end of a resiliently biassed slide means whereby each of said sole holders is pivotal against the biassing force of said slide means, said resiliently biassed slide means effecting an urging of said sole holders toward said sole holding position;
- sole hold-down means and pivotal support means for freely pivotally securing said sole hold-down means to said binding housing and for movement between first and second positions, said sole hold-down means having a downwardly facing surface adapted to engage an upwardly facing surface on said sole of said ski boot, said sole hold-down means further having an upright surface means adapted to engage a side edge of said sole of said ski boot and being movable with said sole hold-down means about said pivotal support means between said first and second positions therefor, said hold-down means being urged from said second position to said first position in response to at least one of said sole holders being urged by said resiliently biassed slide means from said sole releasing position to said sole holding position.
