Abstract
Abstract A ski binding releasable toe clamp includes a pair of rollersupporting rearwardly outwardly projecting clamp arms swingable about and vertically adjustable on a common pivot pin and are provided at their inner ends with symmetrical rear cam surfaces having raised portions between their inner and outer end sections. A cam follower roller is adjustably spring urged toward the cam surfaces so that movement of one of the arms disengages the roller from the other cam surface and each cam is urged inwardly or outwardly when the roller engages the cam surface on the inner or outer side of the rise surface respectively.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
72 words
A safety ski binding comprising a base member, a pair of independently swingable boot clamp arms pivotally mounted about a common vertical axis on said base member, and spring loaded positioning means engaging and resiliently urging said clamp arms to predetermined closed positions and responsive to the movement of one of said arms from said closed position to release and disengage the other of said arms to permit the free swinging thereof.
Claim 2
Dependent Claim
72 words
A safety ski binding comprising a base member, a pair of independently swingable boot clamp arms pivotally mounted about a common vertical axis on said base member, and spring loaded positioning means engaging and resiliently urging said clamp arms to predetermined closed positions and responsive to the movement of one of said arms from said closed position to release and disengage the other of said arms to permit the free swinging thereof.
Claim 3
Dependent Claim
36 words
The safety ski binding of claim 1 wherein the force of said positioning means urging a respective arm to its closed position is diminished when said arm is swung a predetermined angle from said closed position.
Claim 4
Dependent Claim
39 words
The safety ski binding of claim 1 wherein said positioning means urges a respective arm to swing in a direction from said closed position when said arm is in a position exceeding a predetermined angle from said closed position.
Claim 5
Dependent Claim
134 words
A safety ski binding comprising a base member, a vertical pivot pin mounted on the rear section of said base member, a pair of independently swingable boot clamp arms engaging said pivot pin for swinging about the vertical axis thereof and extending forwardly and outwardly from said pivot pin, and spring loaded positioning means resiliently urging said clamp arms to predetermined closed positions and responsive to the movement of one of said arms from said closed position to release and disengage the other of said arms to permit the free swinging thereof and including cams positioned on the forward sections of said clamp arms and having forwardly directed cam surfaces, a common longitudinally moving cam follower registering with said cam surfaces, and spring means urging said cam follower toward engagement with said cam surfaces.
Claim 6
Dependent Claim
134 words
A safety ski binding comprising a base member, a vertical pivot pin mounted on the rear section of said base member, a pair of independently swingable boot clamp arms engaging said pivot pin for swinging about the vertical axis thereof and extending forwardly and outwardly from said pivot pin, and spring loaded positioning means resiliently urging said clamp arms to predetermined closed positions and responsive to the movement of one of said arms from said closed position to release and disengage the other of said arms to permit the free swinging thereof and including cams positioned on the forward sections of said clamp arms and having forwardly directed cam surfaces, a common longitudinally moving cam follower registering with said cam surfaces, and spring means urging said cam follower toward engagement with said cam surfaces.
Claim 7
Dependent Claim
46 words
The safety ski binding of claim 4 wherein each of said cam surfaces has a raised portion relative to said pivot pin between the inner and outer ends of said cam surface, said cam surface extending circumferentially radially inwardly on opposite sides of said raised position.
Claim 8
Dependent Claim
31 words
The safety ski binding of claim 5, wherein said cam follower comprises a roller rotatable about a vertical axis and movable along a medial longitudinal axis relative to said cam surfaces.
Claim 9
Dependent Claim
28 words
The safety ski binding of claim 4 including a roller mounted at the rear free end of each of said clamp arms and rotatable about a vertical axis.
Claim 10
Dependent Claim
34 words
The safety ski binding of claim 7 wherein each of said rollers is supported on the underface of a respective clamp arm with its peripheral face projecting beyond the end of said clamp arm.
Claim 11
Dependent Claim
19 words
The safety ski binding of claim 4 including means for verticaLly adjusting said clamp arms along said pivot pin.
Claim 12
Dependent Claim
27 words
The safety ski binding of claim 4 wherein said clamp arms are provided at their inner forward ends with integrally formed interdigitating knuckles engaging said pivot pin.
