Abstract
Abstract A safety ski binding embodying a release plate intended to be fixedly retained at the ski boot and which can be locked with the ski through the agency of locking pins. According to important aspects of this invention it is contemplated that at the region of at least one end of the release plate there are provided two locking pins disposed adjacent one another to both sides of the central lengthwise axis of the associated ski, these pins cooperating with recesses provided at the relevant end of the release plate in such a manner that during sideward release of the release plate only always one of both locking pins comes into operable play, yet upon loading the release plate towards the top and in the lengthwise direction of the ski both locking pins come into play.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
359 words
A safety ski binding for both lateral and vertical release actions comprising a release plate including means for fixing a ski boot thereto, means on the ski adjacent the front and rear ends of the plate for releasably locking the release plate to the ski, said release means including, said locking pin means comprising only two spring-loaded locking pin members arranged in the region of one end of said release plate adjacent one another and positionable on both sides of a central longitudinal axis of the associated ski, one of said two spring-loaded locking pin members solely participating in the lateral release action of the ski binding to one side and the other of said two spring-loaded locking pin members solely participating in the lateral release action of the ski binding to the opposite side, both of said two spring-loaded locking pin members participating in the vertical release action of the ski binding, said release plate including an end portion confronting said locking pin members for cooperating therewith to releasably lock the plate and the ski, said confronting end portion of said release plate including two projections, a first of said projections engaging beneath both of the locking pin members for acting upon said locking pin members during vertical release action of the safety ski binding, the second of said projections being located only intermediate said two locking pin members, said release plate being of a contour devoid of any projections at the respective opposite lateral sides of the two locking pin members which could prevent free unobstructed lateral movement of the release plate to either side during lateral release action of the safety ski binding, said second projection thereby only effectively acting at any one time during the lateral release action upon a single one of the locking pin members while the other locking pin member is totally ineffectual during such lateral release action to oppose such lateral release action due to said free unobstructed lateral movement, whereby the force needed for the lateral release action of the safety ski binding is automatically less than the force needed for the vertical release action of the safety ski binding.
Claim 2
Dependent Claim
359 words
A safety ski binding for both lateral and vertical release actions comprising a release plate including means for fixing a ski boot thereto, means on the ski adjacent the front and rear ends of the plate for releasably locking the release plate to the ski, said release means including, said locking pin means comprising only two spring-loaded locking pin members arranged in the region of one end of said release plate adjacent one another and positionable on both sides of a central longitudinal axis of the associated ski, one of said two spring-loaded locking pin members solely participating in the lateral release action of the ski binding to one side and the other of said two spring-loaded locking pin members solely participating in the lateral release action of the ski binding to the opposite side, both of said two spring-loaded locking pin members participating in the vertical release action of the ski binding, said release plate including an end portion confronting said locking pin members for cooperating therewith to releasably lock the plate and the ski, said confronting end portion of said release plate including two projections, a first of said projections engaging beneath both of the locking pin members for acting upon said locking pin members during vertical release action of the safety ski binding, the second of said projections being located only intermediate said two locking pin members, said release plate being of a contour devoid of any projections at the respective opposite lateral sides of the two locking pin members which could prevent free unobstructed lateral movement of the release plate to either side during lateral release action of the safety ski binding, said second projection thereby only effectively acting at any one time during the lateral release action upon a single one of the locking pin members while the other locking pin member is totally ineffectual during such lateral release action to oppose such lateral release action due to said free unobstructed lateral movement, whereby the force needed for the lateral release action of the safety ski binding is automatically less than the force needed for the vertical release action of the safety ski binding.
Claim 3
Dependent Claim
41 words
The safety ski binding as defined in claim 1, further including another pair of said locking pin members provided at the opposite end of said release plate, so that said release plate can be locked to the ski at four locations.
Claim 4
Dependent Claim
33 words
The safety ski binding as defined in claim 1, wherein said first projection provided at the end of said release plate confronting said locking pin members comprises a downwardly directed substantially bevelled portion.
Claim 5
Dependent Claim
51 words
The safety ski binding as defined in claim 1, wherein the force required for the lateral release action is approximately one-half of that required for the vertical release action since only half the number of locking pin members are effective during the lateral release action as during the vertical release action.
