Abstract
Abstract A ski brake having a transverse carrier pivotally supported on a ski, which transverse carrier has braking legs which extend perpendicularly with respect to the longitudinal axis of the ski and are arranged at the sides of the ski and can be pivoted into and out of the braking position under spring urging. When the legs are in the braking position, they project substantially perpendicularly downwardly from the ski. The axis of rotation of the transverse carrier is supported on a holding member resiliently mounted on to the ski and effects a resilient holding of the axis of rotation at least in the braking position above and away from the upper surface of the ski.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
231 words
In a ski brake having a holding member and first pivot means for pivotally securing said holding member to a ski for movement about a first axis transverse of the longitudinal axis of said ski, a transverse carrier extending perpendicularly with respect to the longitudinal axis of the ski, second pivot means for pivotally securing said transverse carrier to said holding member for movement about a second axis parallel to said first axis, said transverse carrier having two legs arranged at the sides of said ski, said transverse carrier and said legs being movable about said second axis between a retracted position wherein said legs are positioned above the upper surface of said ski and a braking position wherein the free ends of said legs project substantially perpendicularly downwardly below the bottom surface of said ski, the improvement comprising wherein said first pivot means includes a holding part secured to said ski and wherein resilient means yieldingly urges the end of said holding member remote from said first pivot axis, at least in the braking position of said legs, above and away from the upper surface of said ski and support means supporting said legs for movement relative to said transverse carrier and so that said free ends of said legs move laterally of said longitudinal axis of said ski between positions alongside of and over the top of said ski.
Claim 2
Dependent Claim
231 words
In a ski brake having a holding member and first pivot means for pivotally securing said holding member to a ski for movement about a first axis transverse of the longitudinal axis of said ski, a transverse carrier extending perpendicularly with respect to the longitudinal axis of the ski, second pivot means for pivotally securing said transverse carrier to said holding member for movement about a second axis parallel to said first axis, said transverse carrier having two legs arranged at the sides of said ski, said transverse carrier and said legs being movable about said second axis between a retracted position wherein said legs are positioned above the upper surface of said ski and a braking position wherein the free ends of said legs project substantially perpendicularly downwardly below the bottom surface of said ski, the improvement comprising wherein said first pivot means includes a holding part secured to said ski and wherein resilient means yieldingly urges the end of said holding member remote from said first pivot axis, at least in the braking position of said legs, above and away from the upper surface of said ski and support means supporting said legs for movement relative to said transverse carrier and so that said free ends of said legs move laterally of said longitudinal axis of said ski between positions alongside of and over the top of said ski.
Claim 3
Dependent Claim
32 words
The improved ski brake according to claim 1, wherein said resilient means includes a spring yieldingly engaging and cooperating with said holding member at a location remote from said first pivot axis.
Claim 4
Dependent Claim
42 words
The improved ski brake according to claim 1, wherein said holding member has at least one bent torsion rod anchored thereon with one end being resiliently flexible and slidingly engaging said transverse carrier to urge said transverse carrier into said braking position.
Claim 5
Dependent Claim
30 words
The improved ski brake according to claim 3, wherein said one end of said torsion rod has a low friction covering for reducing the frictional engagement with said transverse carrier.
Claim 6
Dependent Claim
105 words
The improved ski brake according to claim 1, wherein said legs of said transverse carrier consist of a wire spring material, wherein said support means includes third pivot means on said transverse carrier for pivotally supporting said legs on said transverse carrier, and a spring being secured to and extending between the ends of said legs remote from said free ends and which project upwardly in said braking position above the upper surface of said ski for holding said ends of said two legs together, said spring being dimensioned corresponding with the safe swinging back of the legs to said position alongside of said ski.
Claim 7
Dependent Claim
64 words
The improved ski brake according to claim 5, wherein said holding part has a wedge-shaped crossbar projecting upwardly therefrom and wherein as said carrier pivots toward said holding member said ends of said two legs are pivotal into engagement with said crossbar to effect a spreading of said ends when said legs are in said retracted position above the upper surface of said ski.
Claim 8
Dependent Claim
37 words
The improved ski brake according to claim 1, wherein said transverse carrier extends upwardly from said second pivot axis and said legs extend downwardly from said second pivot axis when said legs are in said braking position.
Claim 9
Dependent Claim
55 words
The improved ski brake according to claim 1, wherein said two legs consist of one single, spring wire having two free ends, wherein said support means includes one single holding pin, the center part of said spring wire being wound around said single holding pin and said two free wire ends engage said transverse carrier.
Claim 10
Dependent Claim
41 words
The improved ski brake according to claim 1, wherein said two legs each consist of sheet metal, wherein said support means includes a single pivot pin, said sheet metal being pivotally connected to said transverse carrier by said single pivot pin.
Claim 11
Dependent Claim
19 words
The improved ski brake according to claim 1, wherein said holding part has a wedge-shaped crossbar projecting upwardly therefrom.
Claim 12
Dependent Claim
75 words
The improved ski brake according to claim 1, wherein said resilient means includes at least one bent torsion rod mounted on said holding part with one end being resiliently flexible and slidingly engaging said holding member and wherein the elevated second pivot axis on said holding member is formed by pin means on said holding member and including a spring element between said holding member and said transverse carrier for urging an aligned relation therebetween.
Claim 13
Dependent Claim
31 words
The improved ski brake according to claim 11, wherein said first pivot axis is defined by a pivot pin, said pivot pin pivotally securing said holding part to said holding member.
