Abstract

Abstract This invention relates to safety bindings for skis of the kind having a front binding which consists of two spaced toe-clamps which grip the toe of the boot and which are mounted on outwardly pivotable arms. According to the invention, when these arms are locked in the closed position, they are capable of release in opposition to the pressure of a spring. The force of such spring acts in the direction opposite to the direction of ski movement. In response to a sudden rearward force on the ski, the two toe-clamps can be moved apart simultaneously laterally of the ski a distance greater than the width of the boot.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 136 words
A safety binding for skis having a front binding including two arms each carrying a toe-clamp, such toe-clamps being spaced apart and normally engageable with the toe of a ski-boot, the improvement comprising spring means exerting a predetermined force on the arms in a direction substantially longitudinally and rearwardly of the ski for maintaining the toe-clamps in boot toe engaging position, moving means responsive to a forward force exceeding such predetermined rearward force for simultaneously moving such toe-clamps apart transversely of the ski a distance greater than the width of a ski-boot including pivot means having their axes extending substantially longitudinally of the ski, the arms being swingable about the axis of said pivot means, biasing means for urging simultaneous swinging of the arms about said pivot means, and means for latching the arms against swinging.
Claim 2
Dependent Claim 136 words
A safety binding for skis having a front binding including two arms each carrying a toe-clamp, such toe-clamps being spaced apart and normally engageable with the toe of a ski-boot, the improvement comprising spring means exerting a predetermined force on the arms in a direction substantially longitudinally and rearwardly of the ski for maintaining the toe-clamps in boot toe engaging position, moving means responsive to a forward force exceeding such predetermined rearward force for simultaneously moving such toe-clamps apart transversely of the ski a distance greater than the width of a ski-boot including pivot means having their axes extending substantially longitudinally of the ski, the arms being swingable about the axis of said pivot means, biasing means for urging simultaneous swinging of the arms about said pivot means, and means for latching the arms against swinging.
Claim 3
Dependent Claim 58 words
The safety binding defined in claim 1, in which the arms are rods having their lengths disposed substantially longitudinally of the ski, said rods longitudinally of the ski and axes extending substantially longitudinally of the ski and being displaceable lengthwise, and means for mounting said rods in substantially parallel spaced relationship adjacent to opposite sides of the ski.
Claim 4
Dependent Claim 102 words
The safety binding defined in claim 2, and further having a heel binding including heel-clamps, the improvement further comprising the rearward end portion of a rod projecting rearwardly of the heel binding, latch means for latching such rod against rotation, including a fixed member disposed rearwardly of the heel binding and a member carried by such rod rearward end portion and engageable with said fixed member in the normal boot-clamping position of such rod and disengageable by displacement of such rod, and means for altering the length of the rod portion between the toe-clamp carried by such rod and the heel binding.
Claim 5
Dependent Claim 14 words
The safety binding defined in claim 2, and ski-brake means carried by the rods.
Claim 6
Dependent Claim 22 words
The safety binding defined in claim 1, in which the moving means includes means for moving the arms longitudinally of the ski.
Claim 7
Dependent Claim 33 words
The safety binding defined in claim 1, in which the biasing means are torsion springs carried by each rod, and means for adjusting the force of the spring means and the biasing means.
Claim 8
Dependent Claim 69 words
The safety binding defined in claim 1, and a sole-plate carrying the front binding, the spring means and the moving means, hinge means connecting the forward edge of such sole-plate and a ski and having its hinge axis disposed transversely of the ski, and latch means for latching the rearward edge of said sole-plate for maintaining said sole-plate in a position in substantially parallel overlying relationship with the ski.
