Abstract
A safety ski binding comprises a stirrup mounted to a ski or a sole-plate. Articulated to the stirrup is a toggle mechanism including a spring biased holding member arranged to engage the edge of the sole of a ski boot. The holding member is displaceable in a direction toward the toggle to release the boot upon application of a predetermined minimum separating stress.
Claims8
A safety ski binding for holding a ski boot to a support and permitting separation thereof upon a minimum predetermined separating force which comprises:
- a generally U-shaped stirrup;
- means pivotally mounting the free ends of said stirrup to said support, said stirrup adapted to be rotatable about a first axis transverse to said support and parallel to the upper face thereof, said stirrup being constructed and arranged to encircle an end of said ski boot when positioned on said support;
- a toggle pivotally mounted to the closed end of said stirrup and adapted to be rotatable relative to said stirrup about a second axis parallel to said first axis;
- a holding member movably mounted to said toggle between said first and second axes, said holding member having a boot-engaging section adapted to engage a portion of the sole of said ski boot to maintain said boot in position on said support;
- biasing means housed within said toggle for urging said boot-engaging section of said holding member into a boot-engaging position, said boot-engaging section being movable in a direction toward said toggle and against the action of said biasing means to release said ski boot upon application of said minimum separating force;
- and
- a cam section on said holding member operatively associating said biasing means and said boot-engaging section whereby the boot holding force of said binding is greater than the elastic force of said biasing means.

A safety ski binding for releasably holding a ski boot to a ski which comprises:
- a sole-plate positionable between said ski boot and said ski;
- means for releasably securing said sole-plate to the surface of said ski;
- means for releasably securing a ski boot to said sole plate which comprises a generally U-shaped stirrup mounted to said plate to pivot about a first axis transverse to said plate and parallel to the upper face thereof, said stirrup being constructed and arranged to encircle the heel end of said ski boot when positioned on said plate;
- a toggle pivotably mounted to the closed end of said stirrup and adapted to rotate about a second axis parallel to said first axis, a holding member pivotally mounted to said toggle and adapted to rotate about an axis parallel to and between said first and second axes, said holding member having a boot-engaging section adapted to engage a portion of the sole of said ski boot to maintain said boot in position on said sole-plate, and biasing means housed within said toggle for urging said boot-engaging section of said holding member into a boot-engaging position, said boot-engaging section being displaceable against the action of said biasing means to release said ski boot upon application of a predetermined minimum separating stress, said holding member having a cam section operatively associating said biasing means and said boot-engaging section whereby the boot holding force of said binding is greater than the elastic force of said biasing means.
