Abstract
Abstract A ski binding includes a base portion and a pair of side bootengaging members extending upwardly from the base portion, each of the side members having a hole therein. A crossbridge member extends inwardly from the forward ends of the side members, and a pivot point is provided on the side members below the crossbridge. A flexible, generally U-shaped clamp member is inserted between the side members and is interposed between the crossbridge and the pivot point means with the front portion thereof located forwardly of the pivot point means, and the branches of the clamp member extending rearwardly of the pivot point means. The ends of the branches are bent downwardly toward the base portion and are adapted to be received in the respective holes of the side members. The front portion of the clamp is biased upwardly to force the downwardly bent clamp ends downwardly through the holes in the side member to engage the sole of a boot, thereby securing a boot in inserted position between the side members.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
274 words
A ski binding comprising: a base portion (2) having a pair of side boot-engaging members (3) upwardly extending therefrom and being adapted to engage the forward or toe-end of a ski boot, said side boot-engaging members (e) each having portions which inwardly extend toward the boot, said inwardly extending portions having a generally downwardly extending hole (4'') with a generally downwardly extending axis formed therein; a crossbridge (5) extending inwardly from the forward ends of said side boot-engaging members (3); means (6) on the forward portions of said side boot-engaging members (3) and spaced below said crossbridge (5) for defining a pivot or tilting point; a flexible, generally U-shaped clamp member (9) having a middle portion (9'') and rearwardly extending branches, said clamp member (9) being mounted between said side boot-engaging members (3) and being interposed between said crossbridge (5) and said pivot point defining means (6) with said middle portion (9'') located in front of said pivot point defining means (6) and the branches extending rearwardly of said pivot point defining means (6), the ends (9'''') of said branches being bent down toward the base portion (2) and adapted to be received in respective downwardly extending holes (4'') of said side boot-engaging members (3); and means for biassing said middle portion (9'') of said clamp member (9) in the upward direction, thereby biassing said clamp ends (9'''') downwardly toward said base portion (2) and through said downwardly extending holes (4''), said downwardly biassed clamp ends (9'''') being adapted to bear on the sole of a boot through said holes (4'') to secure a boot in inserted position between said side boot-engaging members (3).
Claim 2
Dependent Claim
274 words
A ski binding comprising: a base portion (2) having a pair of side boot-engaging members (3) upwardly extending therefrom and being adapted to engage the forward or toe-end of a ski boot, said side boot-engaging members (e) each having portions which inwardly extend toward the boot, said inwardly extending portions having a generally downwardly extending hole (4'') with a generally downwardly extending axis formed therein; a crossbridge (5) extending inwardly from the forward ends of said side boot-engaging members (3); means (6) on the forward portions of said side boot-engaging members (3) and spaced below said crossbridge (5) for defining a pivot or tilting point; a flexible, generally U-shaped clamp member (9) having a middle portion (9'') and rearwardly extending branches, said clamp member (9) being mounted between said side boot-engaging members (3) and being interposed between said crossbridge (5) and said pivot point defining means (6) with said middle portion (9'') located in front of said pivot point defining means (6) and the branches extending rearwardly of said pivot point defining means (6), the ends (9'''') of said branches being bent down toward the base portion (2) and adapted to be received in respective downwardly extending holes (4'') of said side boot-engaging members (3); and means for biassing said middle portion (9'') of said clamp member (9) in the upward direction, thereby biassing said clamp ends (9'''') downwardly toward said base portion (2) and through said downwardly extending holes (4''), said downwardly biassed clamp ends (9'''') being adapted to bear on the sole of a boot through said holes (4'') to secure a boot in inserted position between said side boot-engaging members (3).
Claim 3
Dependent Claim
26 words
The ski binding according to claim 1, wherein said inwardly extending portions of said side boot-engaging members (3) extend substantially parallel to said base portion (2).
Claim 4
Dependent Claim
26 words
The ski binding according to claim 1, wherein said base portion (2) and said upwardly extending side boot-engaging members (3) are integrally formed with each other.
Claim 5
Dependent Claim
31 words
The ski binding according to claim 1, wherein said base portion (2), said upwardly extending side boot-engaging members (3) and said inwardly extending portions (4) are integrally formed with each other.
Claim 6
Dependent Claim
33 words
The ski binding according to claim 1, wherein said biassing means is a generally U-shaped plate spring (8) having one end (8'') connected with said middle portion (9'') of said clamp member (9).
Claim 7
Dependent Claim
40 words
The ski binding according to claim 5, wherein the other end portion of said plate spring (8) bears against said base portion (2), said plate spring (8) exerting upward pressure on said forward portion (9'') of said clamp member (9).
