US4231584A — Ski boot heel binding equipped with ski brake

Claim 1

Independent Claim 245 words

A ski boot heel binding equipped with a ski brake comprising: a base plate adapted to be attached to a ski plate; a heel supporting body mounted on said base plate for sliding movement relative thereto in forward and rearward directions, said supporting body having a pair of side walls, an interior chamber, and a forward end supporting a heel engaging jaw; a transverse shaft rotatably supported by said side walls of said supporting body and movable therewith; a ski brake arm rigidly fixed to said transverse shaft and rotatable therewith between a braking position whereat said arm extends below the bottom of the ski plate and a non-braking position whereat said arm is above the bottom of the ski plate; lever means, positioned within said chamber of said supporting body and rigidly fixed to said transverse shaft and connected to a stationary portion of said base plate, for, upon rearward sliding moement of said supporting body when a ski boot is engaged with said jaw, causing said transverse shaft and thereby said arm to rotate to said non-braking position; and spring means, positioned within said chamber of said supporting body, for normally urging said supporting body forwardly with respect to said base plate, and for thereby urging said lever means to rotate said transverse shaft and said arm to said braking position, but allowing rearward movement of said supporting body relative to said base plate when the ski boot is engaged with said jaw.

Claim 2

Dependent Claim 245 words

A ski boot heel binding equipped with a ski brake comprising: a base plate adapted to be attached to a ski plate; a heel supporting body mounted on said base plate for sliding movement relative thereto in forward and rearward directions, said supporting body having a pair of side walls, an interior chamber, and a forward end supporting a heel engaging jaw; a transverse shaft rotatably supported by said side walls of said supporting body and movable therewith; a ski brake arm rigidly fixed to said transverse shaft and rotatable therewith between a braking position whereat said arm extends below the bottom of the ski plate and a non-braking position whereat said arm is above the bottom of the ski plate; lever means, positioned within said chamber of said supporting body and rigidly fixed to said transverse shaft and connected to a stationary portion of said base plate, for, upon rearward sliding moement of said supporting body when a ski boot is engaged with said jaw, causing said transverse shaft and thereby said arm to rotate to said non-braking position; and spring means, positioned within said chamber of said supporting body, for normally urging said supporting body forwardly with respect to said base plate, and for thereby urging said lever means to rotate said transverse shaft and said arm to said braking position, but allowing rearward movement of said supporting body relative to said base plate when the ski boot is engaged with said jaw.

Claim 3

Dependent Claim 67 words

A ski boot heel binding equipped with a ski brake as claimed in claim 1, wherein said lever means comprises first and second levers pivoted to each other at first ends thereof, said first lever being rotatably connected at a second end thereof to said stationary portion of said base plate, and said second lever being rigidly fixed at a second end thereof to said transverse shaft.

Claim 4

Dependent Claim 101 words

A ski boot heel binding equipped with a ski brake as claimed in claim 1, wherein said lever means comprises a single lever rigidly fixed at a first end thereof to said transverse shaft, one of said lever and said stationary portion of said base plate being provided with a cut-out portion and the other of said lever and said stationary portion of said base plate including a pin, said cut-out portion and said pin being engaged with each other in such a manner that when said supporting body slides along said base plate, said lever partially rotates about said pin.

Claim 5

Dependent Claim 56 words

A ski boot heel binding equipped with a ski brake as claimed in claims 1, 2 or 3, wherein said transverse shaft comprises a hollow shaft member rotatably supported by said side walls of said supporting body, said ski brake arm includng a horizontal end portion firmly engaged in the hollow space of said shaft member.

Claim 6

Dependent Claim 45 words

A ski boot heel binding equipped with a ski brake as claimed in claim 3, wherein said lever includes said cut-out portion which is formed to provide bifurcated fingers between which said pin, fixedly provided on said base plate, is interposed to be slidable therebetween.

Claim 7

Dependent Claim 36 words

A ski boot heel binding equipped with a ski brake as claimed in claim 5, wherein said pin is provided on a side wall of a spring-receiving member which is stationary relative to said base plate.

Claim 8

Dependent Claim 43 words

A ski boot heel binding equipped with a ski brake as claimed in claim 6, wherein said spring-receiving member has a horizontal guide slit which allows said transverse shaft to move back and forth when said supporting body slides along said base plate.
