Abstract
Abstract A ski brake pivotally secured to a base plate which in turn is secured to the upper surface of a ski. The ski brake is composed of a brake member having a pair of braking arms and a pair of holding arms. The holding arms are interconnected via a slide piece, on the one hand, or both a slide piece and a crossbar on the other hand. The holding arms are prespring-tensioned into a position diverging away from one another with the slide piece being slidably disposed on the holding arms. The slide piece has a pair of openings therein which receive the holding arms therethrough. Thus, as the slide piece slides along the holding arms, the spacing between the holding arms will be varied in accordance with the position of the slide piece thereon. The slide piece can, if desired, be pivotally secured to the holding plate and the pivot axis therefor located on one side of the pivotal support for the brake member. The member to which the slide piece is attached and which renders it pivotally secured to the mounting plate can be appropriately torqued to generate the erecting force for the ski brake.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
297 words
A brake mechanism for use on skis, comprising: a base plate mounted on a top surface of said ski; a pair of laterally spaced brake members and bearing means supporting said brake members on said base plate for pivotal movement about a pivot axis and for movement toward and away from each other along said pivot axis, said brake members each having a braking arm and a holding arm, said brake members each being pivotal between an operative position wherein said braking arms project beneath a bottom surface of said ski and said holding arms project upwardly away from said top surface of said ski and an inoperative position wherein said braking arms are located above said top surface of said ski and said holding arms extend generally parallel to said top surface of said ski, said holding arms extend at an acute angle to each other when in said operative position; a slide piece having a pair of laterally spaced openings therein each receiving one of said holding arms therethrough, the spacing between said openings corresponding to the lateral spacing between said holding arms at the ends thereof closest the apex of said acute angle and when said holding arms are in said operative position; and means for effecting a sliding of said slide piece along the length of said holding arms in response to a movement of said brake members between said operative and inoperative positions thereof, said slide piece effecting a movement of said brake members toward and away from each other simultaneous with said movement thereof along the length of said holding arms and, particularly, a movement of said braking arms toward each other to said location above said top surface of said ski when said brake members are in said inoperative position.
Claim 2
Dependent Claim
297 words
A brake mechanism for use on skis, comprising: a base plate mounted on a top surface of said ski; a pair of laterally spaced brake members and bearing means supporting said brake members on said base plate for pivotal movement about a pivot axis and for movement toward and away from each other along said pivot axis, said brake members each having a braking arm and a holding arm, said brake members each being pivotal between an operative position wherein said braking arms project beneath a bottom surface of said ski and said holding arms project upwardly away from said top surface of said ski and an inoperative position wherein said braking arms are located above said top surface of said ski and said holding arms extend generally parallel to said top surface of said ski, said holding arms extend at an acute angle to each other when in said operative position; a slide piece having a pair of laterally spaced openings therein each receiving one of said holding arms therethrough, the spacing between said openings corresponding to the lateral spacing between said holding arms at the ends thereof closest the apex of said acute angle and when said holding arms are in said operative position; and means for effecting a sliding of said slide piece along the length of said holding arms in response to a movement of said brake members between said operative and inoperative positions thereof, said slide piece effecting a movement of said brake members toward and away from each other simultaneous with said movement thereof along the length of said holding arms and, particularly, a movement of said braking arms toward each other to said location above said top surface of said ski when said brake members are in said inoperative position.
Claim 3
Dependent Claim
34 words
A brake mechanism according to claim 1, wherein said means for effecting a sliding of said slide piece includes a slide member secured to and extending between said base plate and said slide piece.
Claim 4
Dependent Claim
82 words
A brake mechanism according to claim 1, wherein said brake members are separate from each other and are connected through said slide piece, the ends of said holding arms remote from said braking arms having a greater lateral spacing than at the ends thereof adjacent said braking arms, said slide piece moving from said ends of said holding arms adjacent said braking arms toward said remote ends during a movement of said brake members from said operative position toward said inoperative position.
Claim 5
Dependent Claim
20 words
A brake mechanism according to claim 1, including resilient means for continually urging said brake members to said operative position.
Claim 6
Dependent Claim
40 words
A brake mechanism according to claim 1, wherein said brake members each have an axle segment extending parallel to said top surface of said ski and said pivot axis of which extends perpendicular to the longitudinal axis of said ski.
Claim 7
Dependent Claim
53 words
A brake mechanism according to claim 1, wherein said means for effecting a sliding of said slide piece includes a cam surface on said base plate operatively engaging said slide piece during a movement of said brake members between said operative and inoperative positions to effect said sliding movement of said slide piece.
Claim 8
Dependent Claim
42 words
A brake mechanism according to claim 1, wherein said means for effecting a sliding of said slide piece includes a lever pivotally secured to said base plate and said slide piece, and wherein said lever is elastically prespring-tensioned into the braking position.
Claim 9
Dependent Claim
37 words
A brake mechanism according to claim 1, wherein the ends of said holding arms are connected through a crossbar member for initially prespring tensioning said holding arms at least one of toward and away from one another.
Claim 10
Dependent Claim
75 words
A brake mechanism according to claim 8, wherein the ends of said holding arms remote from said braking arms and adjacent said crossbar member have a smaller lateral spacing than at the ends thereof adjacent said braking arms, said slide piece moving from said ends of said holding arms adjacent said crossbar member toward the ends adjacent said brake arms during a movement of said brake members from said operative position toward said inoperative position.
