Abstract
Abstract A ski brake has a main spring element mounted upon the upper surface of a ski and resiliently biased into an operative position when the ski is released from the ski boot to bring into play at least one brake element, e.g. a blade. In order to protect the brake against impact with stones or the like, an additional spring element is provided between the actuator, which includes a pivotal member received in a mounting plate on the upper surface of the ski, and the blade or brake element so that the latter can yield on impact while retaining its braking function to prevent free flight of the ski.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
150 words
A ski brake for a ski comprising: an actuator swingably mounted on an upper surface of said ski for pivotal movement about a transverse axis substantially parallel to said surface and engageable by a ski boot; spring means bearing upon said actuator for biasing same into an operative position in which said actuator projects upwardly from said surface upon the release thereof by said ski boot; at least one blade element connected to said actuator and displaceable thereby into a braking position in which said blade element lies transversely of the ski to prevent free flight of the ski upon release of said actuator by said ski boot, said blade element being in said braking position when said actuator is in said operative position; and elastic means interposed between said element and said actuator for cushioning forces applied to said spring means upon impact from any direction against said element.
Claim 2
Dependent Claim
150 words
A ski brake for a ski comprising: an actuator swingably mounted on an upper surface of said ski for pivotal movement about a transverse axis substantially parallel to said surface and engageable by a ski boot; spring means bearing upon said actuator for biasing same into an operative position in which said actuator projects upwardly from said surface upon the release thereof by said ski boot; at least one blade element connected to said actuator and displaceable thereby into a braking position in which said blade element lies transversely of the ski to prevent free flight of the ski upon release of said actuator by said ski boot, said blade element being in said braking position when said actuator is in said operative position; and elastic means interposed between said element and said actuator for cushioning forces applied to said spring means upon impact from any direction against said element.
Claim 3
Dependent Claim
100 words
The ski brake defined in claim 1 wherein said ski brake comprises a stirrup-shaped spring wire and said actuator is a substantially planar bight of said wire, and wherein said wire comprises said spring means, said wire having a pair of offset portions connected to said bight and lying in a plane different from the plane of said bight so that displacement of said bight toward said surface distorts said wire resiliently, a pair of such blade elements being provided, said elastic means including an elastic member for each blade element connected to a respective one of said offset portions.
Claim 4
Dependent Claim
31 words
The ski brake defined in claim 2 wherein each of said elastic members comprises a respective loop formed in said wire between the respective blade element and the respective offset portion.
Claim 5
Dependent Claim
33 words
The ski brake defined in claim 2 wherein each of said elastic members comprises at least in part a further wire thinner than said spring wire and connected to the respective blade element.
Claim 6
Dependent Claim
20 words
The ski brake defined in claim 4 wherein said spring and further wires are each connected by a respective sleeve.
Claim 7
Dependent Claim
18 words
The ski brake defined in claim 5 wherein each of said sleeves is composed of an elastic material.
Claim 8
Dependent Claim
38 words
The ski brake defined in claim 4 wherein each of said further wires is formed with a coil spring at an end thereof, said coil spring forming the respective elastic member and being connected to said spring wire.
Claim 9
Dependent Claim
21 words
The ski brake defined in claim 7 wherein said offset portions have respective free ends received in the respective coil springs.
Claim 10
Dependent Claim
25 words
The ski brake defined in claim 4 wherein the modulus of elasticity of the respective further wire is different from that of said spring wire.
Claim 11
Dependent Claim
39 words
The ski brake defined in claim 2 wherein said spring wire is subdivided and has ends spaced apart at a transition between said spring means and said element, said elastic member including a secondary spring bridging said free ends.
Claim 12
Dependent Claim
22 words
The ski brake defined in claim 10 wherein said secondary spring is a coil spring in which said free ends are received.
