Abstract
Abstract A ski brake is formed of spring wire bent so that one end, carrying a plastic brake shoe, forms one brake arm and an intermediate portion, formed into a first loop welded at the top, forms a second brake arm. A transverse portion of the wire, intermediate the pair of brake arms, is rotatably mounted in an open slot of a mounting pad secured to a ski. Extending from the first loop is a second or holding loop. The remaining end of the wire is parallel with the transverse portion and is rotatably mounted in a second open slot in the mounting pad. An anti-friction metal plate covers the mounting pad. A pair of brake stops are located inward of the extending brake arms when in a rest position adjacent the ski upper surface. Each brake stop has a serrated bottom surface clamped against a toothed pad which extends across the ski. A slot and screw adjustment allows each brake stop to be aligned with the side edge of the ski in order to prevent the brake arms from being bent over the ski and thus hanging up during a release condition.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
164 words
A ski brake comprising: mounting means attachable to the upper surface of a ski and having a pair of spaced channels adapted to be located transverse to the longitudinal axis of the ski, a spring wire having a first end forming a first brake arm and an intermediate portion bent into a first loop which forms a second brake arm, the spring wire having an intermediate transverse portion between the first end and the first loop and located in one of the pair of channels, a second end of the spring wire being transverse to the longitudinal axis of the ski and located in the other channel, and the spring wire having an second holding loop between the second end and the first loop which is depressible against the ski and is pivoted upwardly away from the ski by spring action of the wire and configuration thereof to force the pair of brake arms downwardly with respect to the upper surface of the ski.
Claim 2
Dependent Claim
164 words
A ski brake comprising: mounting means attachable to the upper surface of a ski and having a pair of spaced channels adapted to be located transverse to the longitudinal axis of the ski, a spring wire having a first end forming a first brake arm and an intermediate portion bent into a first loop which forms a second brake arm, the spring wire having an intermediate transverse portion between the first end and the first loop and located in one of the pair of channels, a second end of the spring wire being transverse to the longitudinal axis of the ski and located in the other channel, and the spring wire having an second holding loop between the second end and the first loop which is depressible against the ski and is pivoted upwardly away from the ski by spring action of the wire and configuration thereof to force the pair of brake arms downwardly with respect to the upper surface of the ski.
Claim 3
Dependent Claim
36 words
The ski brake of claim 1 wherein the first end of the spring wire has a notch therein, and a molded plastic cap is around the first end including the notch to form the brake arm.
Claim 4
Dependent Claim
30 words
The ski brake of claim 1 including means fixedly securing together portions of the first loop of spring wire which extend toward the intermediate transverse portion and the second loop.
Claim 5
Dependent Claim
22 words
The ski brake of claim 3 wherein the securing means comprises a weld for joining the top portions of the first loop.
Claim 6
Dependent Claim
27 words
The ski brake of claim 1 wherein the first loop is coplanar with the side of the ski to reduce the width of the second brake arm.
Claim 7
Dependent Claim
38 words
The ski brake of claim 1 wherein the extending lengths of the first brake arm and the second brake arm are unequal in order to flip the ski when the brake arms are pivoted into the brake position.
Claim 8
Dependent Claim
51 words
The ski brake of claim 1 wherein the mounting means comprises a pad having a pair of upwardly open slots which form the pair of channels, and an anti-friction plate covers the upper surface of the pad to retain the spring wire therein and to present a low friction upper surface.
Claim 9
Dependent Claim
70 words
The ski brake of claim 1 including a second mounting means located between extending portions of the pair of brake arms when the second holding loop is depressed against the ski, and a pair of brake stops adjustably secured to the second mounting means and oriented thereon to prevent the extending portions of the pair of brake arms from being bent into positions overlapping the upper surface of the ski.
Claim 10
Dependent Claim
29 words
The ski brake of claim 8 wherein the first mounting means and the second mounting means are formed as a unitary molded piece having an intermediate web extending therebetween.
Claim 11
Dependent Claim
90 words
In a ski brake having at least one brake arm movable between a non-activated position adjacent the upper surface of a ski and a brake position extending generally downward with respect to the ski upper surface, the improvement comprising: a brake stop means located adjacent the brake arm when in the non-activated position, and adjustable mounting means for moving the brake stop means to positions generally adjacent the side of the ski to prevent the brake arm from being bent into a hang up position overlapping the ski upper surface.
Claim 12
Dependent Claim
90 words
In a ski brake having at least one brake arm movable between a non-activated position adjacent the upper surface of a ski and a brake position extending generally downward with respect to the ski upper surface, the improvement comprising: a brake stop means located adjacent the brake arm when in the non-activated position, and adjustable mounting means for moving the brake stop means to positions generally adjacent the side of the ski to prevent the brake arm from being bent into a hang up position overlapping the ski upper surface.
Claim 13
Dependent Claim
49 words
The improvement of claim 10 wherein the adjustable mounting means includes a pad securable to the ski upper surface, said mounting means defining a plurality of detented positions, each detented position being capable of withstanding an impact force caused by the extending brake arm striking the brake stop means.
Claim 14
Dependent Claim
