Abstract
Abstract Ski brake comprising a pair of braking members adapted to be disposed on either side of the ski, a transverse pivot pin extending across the ski and about which said members are adapted to pivot, and a control pedal adapted to be actuated either by the ski boot or by a ski-binding plate supporting said ski boot. Said control pedal consists of a rigid metal wire shaped to a bow configuration and rigid with said pair of braking members, and the ski brake also comprises a return spring consisting of a loop of resilient metal wire having one end attached to said control pedal and bearing with the opposite end upon the ski at a point spaced longitudinally in relation to said braking member pivot pin, the dimensions of said resilient wire loop being such that in its normal shape said resilient wire normally urges said control pedal to its raised position above the ski and said braking members to a position in which they project downwardly from the lower surface of the ski.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
233 words
A ski brake of the type adapted to be mounted on a ski and controlled either by the presence or absence of a ski boot or ski binding plate, comprising a pair of rigid braking members disposed on either side of the ski, means pivotally supporting said braking members for vertical movement, mounted transversely of said ski, a brake control pedal positioned on the upper surface of the ski comprising a rigid bow-shaped member having a bow portion positioned above the upper surface of the ski and engageable by the ski boot or ski binding plate, and a pair of side arms respectively rigidly attached to said braking members, spring means normally urging said pedal upwardly and the attached braking means downwardly into a ski-braking position, said spring means comprising a resilient metal wire loop, means pivotally and transversely mounting one side of said loop on said ski, longitudinally displaced thereon relative to the pivotal mounting of said braking members, and means attaching the opposite side of said loop to the bow portion of said control pedal, whereby when said control pedal is depressed by the pressure of the ski boot or ski binding plate said braking means are moved to a substantially horizontal nonbraking position and said wire loop is distorted to provide a return spring action when said pressure is removed to effect a downward braking position of said braking means.
Claim 2
Dependent Claim
233 words
A ski brake of the type adapted to be mounted on a ski and controlled either by the presence or absence of a ski boot or ski binding plate, comprising a pair of rigid braking members disposed on either side of the ski, means pivotally supporting said braking members for vertical movement, mounted transversely of said ski, a brake control pedal positioned on the upper surface of the ski comprising a rigid bow-shaped member having a bow portion positioned above the upper surface of the ski and engageable by the ski boot or ski binding plate, and a pair of side arms respectively rigidly attached to said braking members, spring means normally urging said pedal upwardly and the attached braking means downwardly into a ski-braking position, said spring means comprising a resilient metal wire loop, means pivotally and transversely mounting one side of said loop on said ski, longitudinally displaced thereon relative to the pivotal mounting of said braking members, and means attaching the opposite side of said loop to the bow portion of said control pedal, whereby when said control pedal is depressed by the pressure of the ski boot or ski binding plate said braking means are moved to a substantially horizontal nonbraking position and said wire loop is distorted to provide a return spring action when said pressure is removed to effect a downward braking position of said braking means.
Claim 3
Dependent Claim
29 words
Ski brake according to claim 1, wherein said spring-forming resilient metal wire loop is disposed between the side arms of said rigid metal wire bow constituting said control pedal.
Claim 4
Dependent Claim
56 words
Ski brake according to claim 1, in which the means pivotally mounting said braking members comprise a second rigid bow having its horizontal portion pivotally mounted on said ski, in combination with means rigidly attaching its side arms to the respective side arms of the first bow to form with them said pair of braking members.
Claim 5
Dependent Claim
32 words
Ski brake according to claim 2, in which said braking members are formed by extended portions of said side arms, and in which said pivotally supporting means pivotally support such extended portions.
Claim 6
Dependent Claim
48 words
Ski brake according to claim 4, in which the extended portions of said side arms are each first bent at a substantially right angle to form a transverse portion supported by said pivotally supporting means, and then bent again at a right angle to form said braking members.
