Abstract
Abstract A safety binding assembly for attachment to a ski for interaction with a ski boot, including a standardized cam means mounted to the bottom of the boot whereby the identical binding mechanism will be used regardless of the size of the boot. The binding itself includes a bifurcated plate having upstanding ears adapted to interact with the cam upon the boot and biasing means continuously urging the two legs of the plate to a proximate relationship. A second plate overlies a first plate to prevent the first plate from becoming inoperative due to compact snow and ice as well as providing a smooth, safe surface. For securement of the boot to or removal from the ski, the biasing means is overridden allowing the legs of the bifurcated plate to be separated sufficiently to allow removal of the boot mounted cam.

Claim 1
Independent Claim
223 words
A safety binding assembly for attachment to a ski and interaction with a ski boot serving as the only means for securing the boot to the ski comprising; a first elongated bifurcated plate for attachment to the ski in a fashion which permits movement of one leg relative to the other but prevents movement longitudinally of the ski, said plate including a first upstanding ear having an inwardly projecting portion upon the outside edge of each leg in opposed relationship and a second upstanding ear upon the inside edge of each leg at the aftermost end of the leg, said second upstanding ears being in opposed contiguous relationship, a second elongated plate adapted to overlie the first plate between the first set of ears and terminate forwardly of the second set of ears, biasing means yieldingly continuously urging the upstanding ears of the first plate into a contiguous relationship whereat the legs are proximate each other, and means mounted upon a ski boot for interaction with the first set of upstanding ears, said means being rigid, of a fixed predetermined length and having an outwardly projecting portion configured to interact with the inwardly projecting portion of the ears, resisting movement in all directions but releasing the boot upon the application of excessive pressure which overrides the biasing means and moves the ears outwardly.

Claim 3
Dependent Claim
29 words
A safety binding as in claim 1 wherein the first set of upstanding ears includes inwardly projecting roller means and the boot mounted means has a complementary cam surface.
Claim 4
Dependent Claim
41 words
A safety binding as in claim 1 wherein the biasing means is a spring of the compression type and is held in position by an adjustable member extending from one ear through the second ear and terminates in a compression plate.
