Abstract
Abstract A releasable ski binding of the type incorporating a release plate anchored at the ski to be releasable to all sides, the release plate being retained at least at its one end by a springloaded locking element. The locking element is pivotably mounted about an axis extending transversely with respect to the lengthwise direction of the ski, and under the action of its spring, in the normal position of the release plate, bears upon a central section or region of a guide track. The guide track possesses to both sides of such central region step-like and/or continuously raised sections.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
A releasable ski binding comprising a release plate capable of being anchored to the ski so as to be releasable to all sides, a spring-loaded locking element for releasably holding at least one end of the release plate against the ski, means for mounting the spring-loaded locking element to pivot about an axis directed transversely with respect to the lengthwise direction of the associated ski, said spring-loaded locking element being provided with a roller, a guide track mounted on the release plate, said guide track being provided with a roller defining at least a central section of the guide track, the spring of said springloaded locking element urging said locking element in the normal position of the release plate to bear via its roller against the roller defining the central section of the guide track, said central section of the guide track being bounded to each side by a raised section.
Claim 2
Dependent Claim
151 words
A releasable ski binding comprising a release plate capable of being anchored to the ski so as to be releasable to all sides, a spring-loaded locking element for releasably holding at least one end of the release plate against the ski, means for mounting the spring-loaded locking element to pivot about an axis directed transversely with respect to the lengthwise direction of the associated ski, said spring-loaded locking element being provided with a roller, a guide track mounted on the release plate, said guide track being provided with a roller defining at least a central section of the guide track, the spring of said springloaded locking element urging said locking element in the normal position of the release plate to bear via its roller against the roller defining the central section of the guide track, said central section of the guide track being bounded to each side by a raised section.
Claim 3
Dependent Claim
31 words
The releasable ski binding as defined in claim 1, wherein the raised section at each side of the central section of the giude track is raised in a substantially step-like manner.
Claim 4
Dependent Claim
31 words
The releasable ski binding as defined in claim 1, wherein the raised section at each side of the central section of the guide track is raised in a substantially continuous manner.
Claim 5
Dependent Claim
55 words
The releasable ski binding as defined in claim 1, wherein the roller defining at least the central section of the guide track is tapered at its central region, and means mounting said tapered roller at the release plate for rotation about an axis directed transversely with respect to the lengthwise direction of the release plate.
Claim 6
Dependent Claim
35 words
A releasable ski binding as defined in claim l, wherein said guide track includes a portion which deviates back, starting from the region of its central section, in the lengthwise direction of the release plate.
Claim 7
Dependent Claim
32 words
A releasable ski binding as defined in claim 1, further including roller means for displaceably supporting the release plate towards the side at the ski at the region of the guide track.
Claim 8
Dependent Claim
57 words
The releasable ski binding as defined in claim 1, further including a spring-loaded locking element for retaining the other end of the release plate at the ski, said second locking element bearing upon a flat guide track of the release plate, and plug pin means for fixing the release plate in the lengthwise direction of the ski.
Claim 9
Dependent Claim
31 words
The releasable ski binding as defined in claim 1, wherein each roller has an axis of rotation, said axes of rotation of said rollers extending transversely with respect to one another.
