Abstract
Abstract A brake for a ski has a holder defining a pivot transverse to the ski and parallel to the upper surface thereof. A resiliently deformable wire has a central bight portion defining a plane, a pair of pivot portions confined in the holder pivot and bent inwardly toward each other out of the plane of the bight portion, a pair of connecting portions bent away from the pivot portions and extending outwardly away from each other toward the sides of the ski and a pair of leg portions extending generally parallel to each other from the connecting portions and lying out of the plane. The wire is symmetrical about a plane perpendicular to the surface and extending longitudinally of the ski. A braking element is carried on each of the leg portions, and is displaceable between a position in which it projects below the lower surface of the ski and a position in which it lies above this lower surface and within the lateral outline of the ski on displacement of the bight portion by the heel or toe of a skiboot.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
214 words
A brake for a ski adapted to be actuated by a skiboot, said brake comprising: a holder secured to said ski and defining a pair of passages parallel to the upper surface of said ski; a resiliently deformable wire having a central bight portion defining a plane, a pair of pivot portions respectively received in said passages and bent inwardly toward each other out of said plane from said bight portion, a pair of connecting portions bent away from said pivot portions and extending outwardly away from each other toward the sides of said ski, and a pair of leg portions extending generally parallel to each other from said connecting portions and lying out of said plane, said passages including an inner edge shaped to contact and guide said pivot portion to resiliently deform said wire and cause said leg portions to swing inwardly and upwardly upon depression of said bight portion by said skiboot, the resilient deformation of said wire causing the leg portions to swing outwardly and downwardly upon release of the bight portion by said skiboot; and a braking element on each of said leg portions, said holder being formed with a pair of slots which taper toward the outside edge of said ski and each constituting one of said passages.
Claim 2
Dependent Claim
214 words
A brake for a ski adapted to be actuated by a skiboot, said brake comprising: a holder secured to said ski and defining a pair of passages parallel to the upper surface of said ski; a resiliently deformable wire having a central bight portion defining a plane, a pair of pivot portions respectively received in said passages and bent inwardly toward each other out of said plane from said bight portion, a pair of connecting portions bent away from said pivot portions and extending outwardly away from each other toward the sides of said ski, and a pair of leg portions extending generally parallel to each other from said connecting portions and lying out of said plane, said passages including an inner edge shaped to contact and guide said pivot portion to resiliently deform said wire and cause said leg portions to swing inwardly and upwardly upon depression of said bight portion by said skiboot, the resilient deformation of said wire causing the leg portions to swing outwardly and downwardly upon release of the bight portion by said skiboot; and a braking element on each of said leg portions, said holder being formed with a pair of slots which taper toward the outside edge of said ski and each constituting one of said passages.
Claim 3
Dependent Claim
31 words
The brake defined in claim 2 wherein said holder is formed with a pair of slots open toward and closed by said surface and each constituting a one of said passages.
Claim 4
Dependent Claim
41 words
The brake defined in claim 1 wherein said holder has a relatively thick rear portion formed with said pivot and a relatively thin front portion adapted to receive a ski-binding heel clamp, said portions being integral and separated by a ledge.
Claim 5
Dependent Claim
28 words
The brake defined in claim 1 wherein said bight portion has a region bent out of said plane and a bend connecting said region to said bight portion.
Claim 6
Dependent Claim
39 words
The brake defined in claim 4 wherein said wire is provided at said bend with resilient means for normally urging said region into a position bent away from said plane of said bight portion and toward said upper surface.
Claim 7
Dependent Claim
13 words
The brake defined in claim 4, further comprising a hinge at said bend.
Claim 8
Dependent Claim
49 words
The brake defined in claim 1 wherein said pivot portions are bent inwardly from said bight portion and lie in an unstressed condition of said wire at an angle to said plane and to a plane perpendicular thereto, said wire being stressed when subjected to the said resilient deformation.
Claim 9
Dependent Claim
15 words
The brake defined in claim 7 wherein said connecting portions are straight and generally coaxial.
Claim 10
Dependent Claim
234 words
A brake for a ski adapted to be actuated by a skiboot, said brake comprising: a holder secured to said ski and defining a pair of passages parallel to the upper surface of said ski; a resiliently deformable wire having a central bight portion defining a plane, a pair of pivot portions respectively received in said passages and bent inwardly toward each other out of said plane from said bight portion, a pair of connecting portions bent away from said pivot portions and extending outwardly away from each other toward the sides of said ski, and a pair of leg portions extending generally parallel to each other from said connecting portions and lying out of said plane, said passages including an inner edge shaped to contact and guide said pivot portion to resiliently deform said wire and cause said leg portions to swing inwardly and upwardly upon depression of said bight portion by said skiboot, the resilient deformation of said wire causing the leg portions to swing outwardly and downwardly upon release of the bight portion by said skiboot; and a braking element on each of said leg portions, said holder being formed with a pair of slots and each constituting one of said passages, each passage tapering toward the respective ski edge and has at its outer end a cross-sectional area slightly greater than the cross-sectional area of said wire at said end.
Claim 11
Dependent Claim
234 words
A brake for a ski adapted to be actuated by a skiboot, said brake comprising: a holder secured to said ski and defining a pair of passages parallel to the upper surface of said ski; a resiliently deformable wire having a central bight portion defining a plane, a pair of pivot portions respectively received in said passages and bent inwardly toward each other out of said plane from said bight portion, a pair of connecting portions bent away from said pivot portions and extending outwardly away from each other toward the sides of said ski, and a pair of leg portions extending generally parallel to each other from said connecting portions and lying out of said plane, said passages including an inner edge shaped to contact and guide said pivot portion to resiliently deform said wire and cause said leg portions to swing inwardly and upwardly upon depression of said bight portion by said skiboot, the resilient deformation of said wire causing the leg portions to swing outwardly and downwardly upon release of the bight portion by said skiboot; and a braking element on each of said leg portions, said holder being formed with a pair of slots and each constituting one of said passages, each passage tapering toward the respective ski edge and has at its outer end a cross-sectional area slightly greater than the cross-sectional area of said wire at said end.
