Abstract
Abstract A ski brake for automatic release upon lifiting of a ski boot from the surface of a ski so as to prevent free flight thereof comprises a spring-loaded brake element adapted to reach downwardly below the bottom surface of the ski. A bent wire forms a bight which can be engaged by the ski boot and carries the brake element. A tread plate is disposed on the bight and is connected by another element, e.g. another bent wire, to the mounting structure for the ski brake.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
192 words
A brake for a ski automatically operable to prevent free flight thereof upon the release of the ski from a skiboot, said brake comprising: a support on the upper surface of said ski having a passage; an actuator comprising first and second bent spring wires engaged in said passage and swingable on said support about respective spaced axes, said spring wires forming a force-storing means tending to swing said actuator into an upstanding position on said support from a rest position by subjecting said first spring wire to greater elastic deformation in said rest position than in said upstanding position, said wires being generally coplanar in one of said positions; a brake element on one of said spring wires extending transversely to the ski in said upstanding position of said actuator and downwardly into snow underneath said ski, said actuator being displaceable into a position lying along said surface and wherein said element is swung out of its transverse position and said wires into said rest position; and a tread plate connecting said spring wires at spaced pivotal locations and displaceable by said ski boot to press said actuator toward said surface.
Claim 2
Dependent Claim
192 words
A brake for a ski automatically operable to prevent free flight thereof upon the release of the ski from a skiboot, said brake comprising: a support on the upper surface of said ski having a passage; an actuator comprising first and second bent spring wires engaged in said passage and swingable on said support about respective spaced axes, said spring wires forming a force-storing means tending to swing said actuator into an upstanding position on said support from a rest position by subjecting said first spring wire to greater elastic deformation in said rest position than in said upstanding position, said wires being generally coplanar in one of said positions; a brake element on one of said spring wires extending transversely to the ski in said upstanding position of said actuator and downwardly into snow underneath said ski, said actuator being displaceable into a position lying along said surface and wherein said element is swung out of its transverse position and said wires into said rest position; and a tread plate connecting said spring wires at spaced pivotal locations and displaceable by said ski boot to press said actuator toward said surface.
Claim 3
Dependent Claim
22 words
The brake defined in claim 1 wherein each of said spring wires has a respective bight, said tread plate connecting said bights.
Claim 4
Dependent Claim
29 words
The brake defined in claim 2 wherein said one of said spring wires has a pair of such brake elements and the other spring wire is said first wire.
