Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 211 words
A ski boot heel binding device comprising a base plate fixedly mounted on a ski, a holding frame, means mounting said holding frame on said base plate for movement in the longitudinal direction of the ski, heeling engaging means pivotally mounted on said holding frame, said holding frame having means defining an opening, swing crank means pivotally mounted on said holding frame, a lever having one end portion pivotally mounted on said swing crank means and the other end portion pivotally mounted on said heel engaging means, means defining a groove in said swing crank means, said groove being generally aligned with said opening in said holding frame, a slide crank pin carried in and freely slidable along said aligned groove and opening, spring means biasing said slide crank pin in a direction towards the heel of the ski boot, whereby said spring means is operative to urge said heel engaging means in either one of two pivotal positions wherein in one position, the ski boot heel is engaged and in the other position the ski boot heel is released, and a release means mounted on said slide crank pin and operable to be manually actuated to pivot said heel engaging means from its heel engaging to its heel release position.
Claim 2
Dependent Claim 211 words
A ski boot heel binding device comprising a base plate fixedly mounted on a ski, a holding frame, means mounting said holding frame on said base plate for movement in the longitudinal direction of the ski, heeling engaging means pivotally mounted on said holding frame, said holding frame having means defining an opening, swing crank means pivotally mounted on said holding frame, a lever having one end portion pivotally mounted on said swing crank means and the other end portion pivotally mounted on said heel engaging means, means defining a groove in said swing crank means, said groove being generally aligned with said opening in said holding frame, a slide crank pin carried in and freely slidable along said aligned groove and opening, spring means biasing said slide crank pin in a direction towards the heel of the ski boot, whereby said spring means is operative to urge said heel engaging means in either one of two pivotal positions wherein in one position, the ski boot heel is engaged and in the other position the ski boot heel is released, and a release means mounted on said slide crank pin and operable to be manually actuated to pivot said heel engaging means from its heel engaging to its heel release position.
Claim 3
Dependent Claim 57 words
