Abstract
Abstract Safety release for ski binding for direct engagement between the upper side of a ski and the under side of a boot sole. Generally elongated and substantially rectangularly shaped means are arranged transversely of the ski, are fastened thereto and project upwardly therefrom. Resiliently loaded clamp means are contained within the boot sole within a cavity which also receives said upwardly projecting means when the boot is placed in position of use on the ski. In such position said clamping means engage the upwardly projecting means with a resiliently generated force but are retractable to permit release of the ski when said gripping force or engaging force is overcome. The generally rectangular shape of the upwardly projecting member aids in restoration of the boot to normal operating position after lateral displacement therefrom whenever said lateral displacement is insufficient to effect a complete release.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
266 words
A releasable ski binding for releasably securing the sole of a ski boot to a ski, comprising: post means fixedly secured to said ski and extending upwardly therefrom and having means defining a pair of locking recesses thereon each facing in opposite longitudinal directions relative to said ski; housing means mounted on the sole of said ski boot; first locking means mounted on said housing means; second locking means mounted on said housing means and adapted to move longitudinally parallel to the longitudinal axis of said ski boot toward and away from said first locking means, an opening being defined between said first locking means and said second locking means when said first and second locking means are moved away from each other for receiving said post means therein, said first and second locking means both being adapted to engage said post means, while in said opening, in one of said locking recesses; and resilient means for effecting and urging together of said first and second locking means into engagement with said post means, said first and second locking means being movable out of engagement with said recesses against the force of said resilient means to effect a release of the ski binding whenever said longitudinal axis of said sole of said ski boot is twisted out of parallel relationship with the longitudinal axis of the ski beyond a predetermined angular displacement, said resilient means effecting a restoration of said boot to a normal operating position whenever the twisted angular displacement of said ski boot relative to the ski is less than said predetermined angular displacement.
Claim 2
Dependent Claim
266 words
A releasable ski binding for releasably securing the sole of a ski boot to a ski, comprising: post means fixedly secured to said ski and extending upwardly therefrom and having means defining a pair of locking recesses thereon each facing in opposite longitudinal directions relative to said ski; housing means mounted on the sole of said ski boot; first locking means mounted on said housing means; second locking means mounted on said housing means and adapted to move longitudinally parallel to the longitudinal axis of said ski boot toward and away from said first locking means, an opening being defined between said first locking means and said second locking means when said first and second locking means are moved away from each other for receiving said post means therein, said first and second locking means both being adapted to engage said post means, while in said opening, in one of said locking recesses; and resilient means for effecting and urging together of said first and second locking means into engagement with said post means, said first and second locking means being movable out of engagement with said recesses against the force of said resilient means to effect a release of the ski binding whenever said longitudinal axis of said sole of said ski boot is twisted out of parallel relationship with the longitudinal axis of the ski beyond a predetermined angular displacement, said resilient means effecting a restoration of said boot to a normal operating position whenever the twisted angular displacement of said ski boot relative to the ski is less than said predetermined angular displacement.
Claim 3
Dependent Claim
110 words
A releasable ski binding according to claim 1, wherein said first locking means includes a first locking element and first support means for supporting said first locking element for movement relative to said housing means and toward and away from one side of said post means in a direction parallel to the longitudinal axis of said ski boot; and wherein said second locking means includes a second locking element and second support means for supporting said second locking element for movement relative to said housing means and toward and away from the other side of said post means in a direction parallel to the longitudinal axis of said ski boot.
Claim 4
Dependent Claim
45 words
A releasable ski binding according to claim 2, wherein a horizontal section through said post means has a rectangular cross section; and wherein said locking recesses arranged on the opposite longitudinally facing surfaces of said post means are centrally positioned on said oppositely facing surfaces.
Claim 5
Dependent Claim
26 words
A releasable ski binding according to claim 3, wherein the plane of said oppositely facing longitudinal surfaces extends transversely of said longitudinal axis of said ski.
Claim 6
Dependent Claim
49 words
A releasable ski binding according to claim 2, wherein said first and second locking elements each has a projection thereon adapted to be received in one of said locking recesses, at least one of said projections being removed from a corresponding locking recess during a ski boot releasing operation.
Claim 7
Dependent Claim
35 words
A releasable ski binding according to claim 1, wherein said post means includes means defining a tapered upper portion, said tapered upper portion terminating at a line perpendicular to the longitudinal axis of said ski.
Claim 8
Dependent Claim
29 words
A releasable ski binding according to claim 6, wherein said tapered upper portion beings at a location at least as low as the lowermost portion of said locking recesses.
Claim 9
Dependent Claim
31 words
A releasable ski binding according to claim 1, including manually operable means for manually separating said first and sEcond locking means so that said post means will not be engaged thereby.
