Abstract
Abstract A safety ski binding embodying a release plate intended to be releasably secured to a ski boot. The release plate possesses at one end a supporting surface engaging beneath an associated holding surface of a holder element secured to the ski and the other end of which cooperates with a locking pin subjected to the pressure of an adjustment spring, so that there is possible both lateral release of the release plate as well as also upward release thereof away from the ski. A circular-shaped bearing disc is secured to the ski and engages with a lengthwise extending slot of the release plate, so that the release plate can pivot about the bearing disc, can displace in the lengthwise direction with respect to the bearing disc and can be raised therefrom. The supporting surface of the release plate and the holding surface of the holder element form a lateral guide with regard to the axis of the bearing disc.

Claim 1
Independent Claim
269 words
A releasable ski binding for a ski comprising a release plate intended to be releasably secured to a ski boot, said release plate being provided at one end with a supporting surface, a holder element for attachment to the ski, said holder element including a holding surface which engages with the supporting surface of the release plate, a spring-loaded locking pin cooperating with the other end of the release plate, means for adjusting the spring-loading of said spring-loaded locking pin, said release plate being releasable laterally as well as upwardly with regard to the ski, a substantially circular-shaped bearing disc for attachment to the ski, said release plate having a lengthwise extending slot which engages said bearing disc, so that said release plate can pivot about the bearing disc, can displace in the lengthwise direction relative thereto and can be raised away from said bearing disc, said supporting surface of the release plate and the holding surface of the holder element forming a lateral guide with regard to the axis of the bearing disc, said supporting surface of the release plate and the holding surface of the holder element cooperating with one another to provide selective vertical release action, said lateral guide having an arcuate surface cooperating with an arcuate surface of said release plate for freely permitting pivoting of said release plate, said spring-loaded locking pin providing both lateral release action and vertical release action for said binding, said spring-loaded Locking pin in conjunction with said bearing disc providing different release moments for the ski binding for the vertical release action and for the lateral release action, respectively.
Claim 2
Dependent Claim
269 words
A releasable ski binding for a ski comprising a release plate intended to be releasably secured to a ski boot, said release plate being provided at one end with a supporting surface, a holder element for attachment to the ski, said holder element including a holding surface which engages with the supporting surface of the release plate, a spring-loaded locking pin cooperating with the other end of the release plate, means for adjusting the spring-loading of said spring-loaded locking pin, said release plate being releasable laterally as well as upwardly with regard to the ski, a substantially circular-shaped bearing disc for attachment to the ski, said release plate having a lengthwise extending slot which engages said bearing disc, so that said release plate can pivot about the bearing disc, can displace in the lengthwise direction relative thereto and can be raised away from said bearing disc, said supporting surface of the release plate and the holding surface of the holder element forming a lateral guide with regard to the axis of the bearing disc, said supporting surface of the release plate and the holding surface of the holder element cooperating with one another to provide selective vertical release action, said lateral guide having an arcuate surface cooperating with an arcuate surface of said release plate for freely permitting pivoting of said release plate, said spring-loaded locking pin providing both lateral release action and vertical release action for said binding, said spring-loaded Locking pin in conjunction with said bearing disc providing different release moments for the ski binding for the vertical release action and for the lateral release action, respectively.
Claim 3
Dependent Claim
40 words
The releasable ski binding as defined in claim 1, wherein the release plate contacts the bearing disc at one end of the lengthwise extending slot under the action of the locking pin in the normal non-release condition of the binding.
Claim 4
Dependent Claim
41 words
The releasable ski binding as defined in claim 1, wherein the supporting surface of the release plate and the holding surface of the holder element extend in respective substantially circular arc-shaped configuration with regard to the axis of the bearing disc.
Claim 5
Dependent Claim
34 words
The releasable ski binding as defined in claim 1, wherein the supporting surface and the holding surface are respectively inclined from the bottom towards the top thereof in the direction of the bearing disc.
Claim 6
Dependent Claim
18 words
The releasable ski binding as defined in claim 1, wherein said locking pin comprises a pivotal pin member.
Claim 7
Dependent Claim
19 words
The releasable ski binding as defined in claim 1, wherein said locking pin comprises an axially displaceable pin member.
Claim 8
Dependent Claim
204 words
In a releasable ski binding for a ski including a release plate and means for securing said release plate to a ski boot, the combination comprising first holding means adapted to be secured to said ski juxtaposed with the toe end of said boot, for releasably holding one end of said release plate relative to said ski, second holding means adapted to be secured to said ski at the opposite end of said release plate juxtaposed with the heel end of said boot for releasably holding said opposite end of said release plate against upward motion relative to said ski, said second holding means having an arcuate surface cooperating with a corresponding surface of said release plate for permitting unrestrained lateral movement of said release plate relative to said ski and pivot means adapted to be secured to said ski at a point intermediate said first and second holding means and cooperating with said release plate to permit said release plate to pivot relative to said ski at the location of said pivot means and permitting vertical separation of said release plate from said ski while preventing sidewise movement of said release plate relative to said ski at the location of said pivot means.
