Abstract

A structure for a use in either an anti-crossing device for skis or a ski brake. A torsion spring is utilized to urge a projection member to an upright position on the ski. In the anti-crossing device for skis, the resilient projection member will prevent movement of a ski to the crossed position in one direction while simultaneously permitting movement of the ski in the opposite direction by flexing the resilient projection downwardly onto the upper surface of the ski. In the ski brake environment, the ski boot effects a resilient flexing of the projection member down onto the upper surface of the ski when the ski boot is mounted between the ski bindings. The resilient projection member has extension members which project below the lower surface of the ski when the resilient projection member is in the upright position.

Claims

1. A ski brake apparatus for skis comprising an upstanding bracket adapted to extend substantially transversely across its associated ski, means mounting the upstanding bracket for pivotable movement about a transverse axis into a position bearing substantially flatly against the top surface of the ski, said upstanding bracket comprising a resilient spring bracket member having two axle segments, said two axle segments extending transversely to the ski in substantially parallel relationship to one another and terminating at a free end thereof located on said top surface of said ski, said axle segments being spaced from each other in the longitudinal direction of the ski and serving as pivot shafts for the spring bracket member, said spring bracket member having elongated brake arm means thereon and adjacent an end of each of said axle segments remote from said free end thereof which, when said spring bracket member is in said upstanding position, project beneath and beyond the undersurface of said ski, said mounting means comprising a base body, said two axle segments of spring bracket member being pivotably mounted in said base body, the spring bracket member and the pivotable mounting of the axle segments thereof enabling said spring bracket member to resiliently tilt over in the longitudinal direction of said associated ski in the event a user of said ski pushes down upon said spring bracket member with a ski boot, and to return to its upstanding position after the ski boot releases its engagement therewith, said free end of each of said two axle segments remote from said brake arm means including a free end segment extending coextensively with the longitudinal axes of said ski, said mounting means including further means for holding said free end segments in a position parallel to said top surface of said ski.

2. The ski brake apparatus according to claim 1, wherein said resilient spring bracket member, viewed in the lengthwise direction of its associated ski, possesses the shape of a rectangle having two upstanding sides, a top and said two axle segments forming a base, the longitudinal axis of said top extending in a plane perpendicular to said top surface of said ski and which is angularly related to two planes each perpendicular to said top surface of said ski and which contain the longitudinal axes of said two axle end segments.

3. The ski brake apparatus according to claim 2, wherein said brake arm means are attached to each of said two upstanding sides.

4. The ski brake apparatus according to claim 2, wherein said brake arm means are integrally formed with said resilient spring bracket member and consist of a U-shaped wire segment connected to and extending between the mutually adjacent ends of each of said two axle end segments and said two upstanding sides.

5. The ski brake apparatus according to claim 4, wherein said U-shaped wire segment is enveloped with a solid material.

6. The ski brake apparatus according to claim 1, wherein each of said free end segments extends generally parallel to the longitudinal axis of said ski.
