Abstract
Abstract A brake for roller skates comprising a simple, lightweight mechanism which multiplies the force exerted by the skater into a substantial braking force. The force is exerted by the skater by pushing downward with the heel, which rotates the boot with respect to the frame of the skate. That force is transmitted with leverage to braking shoes or pads that impinge on brake drums adjacent to the wheels. Adjustment for brake wear is provided by a screw that compensates for the shortening of the brake shoe as normal wear occurs. A detent mechanism locks the boot and frame together during normal skating.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
203 words
A roller skate brake comprising: a) a boot including: a flange with holding means for rotatably holding a shaft, b) a frame including: flange means with holding means for rotatably holding said shaft of said boot flange and for movably mounting said boot to said frame, sidewalls on said frame adapted to mount a plurality of axles, c) a wheel mounted to each of said plurality of axles, said wheel mounted on said axles being in a common plane a plurality of said wheels including a braking drum, d) a brake assembly consisting of: a brake mount, and a brake pad secured to said brake mount and adapted to cooperate with said braking drum, e) an actuating rod constrained to move in a single plane and primarily in a forward and rearward direction relative to said frame, f) and a first connecting means between said boot and said actuating rod and a second connecting means between said actuating rod and said brake mount such that movement of a portion of said boot relative to said frame about said movable mounting causes a force to be exerted on said brake mount through said actuating rod to engage said brake pad with said braking drum.
Claim 2
Dependent Claim
203 words
A roller skate brake comprising: a) a boot including: a flange with holding means for rotatably holding a shaft, b) a frame including: flange means with holding means for rotatably holding said shaft of said boot flange and for movably mounting said boot to said frame, sidewalls on said frame adapted to mount a plurality of axles, c) a wheel mounted to each of said plurality of axles, said wheel mounted on said axles being in a common plane a plurality of said wheels including a braking drum, d) a brake assembly consisting of: a brake mount, and a brake pad secured to said brake mount and adapted to cooperate with said braking drum, e) an actuating rod constrained to move in a single plane and primarily in a forward and rearward direction relative to said frame, f) and a first connecting means between said boot and said actuating rod and a second connecting means between said actuating rod and said brake mount such that movement of a portion of said boot relative to said frame about said movable mounting causes a force to be exerted on said brake mount through said actuating rod to engage said brake pad with said braking drum.
Claim 3
Dependent Claim
64 words
The roller skate brake of claim 1 wherein said holding means for rotatably holding said shaft of said boot flange and for rotatably mounting said boot to said frame is a hinge connection of said boot to said frame, whereby said movement of said portion of said boot about said hinge connection causes movement of said brake pad with respect to said brake drum.
Claim 4
Dependent Claim
39 words
The roller skate brake of claim 1 wherein said first connecting means between said boot and said actuating rod includes a leverage mechanism that converts movement of said boot to engagement of said brake pads with said brake drum.
Claim 5
Dependent Claim
33 words
The roller skate brake of claim 1 including a releasable detent connection means between said boot and said frame whereby said brake assembly is maintained inoperative until said detent connection is selectively released.
Claim 6
Dependent Claim
47 words
The roller skate brake of claim 1 wherein said brake assembly includes a brake pad cooperationg with a brake drum on a plurality of said wheels and said force exerted on said actuating rod causes brake pad and brake drum engagement on said plurality of said wheels.
Claim 7
Dependent Claim
39 words
The roller skate brake of claim 1 including means on said first connecting means between said boot and said actuating rod for adjusting an effective length of said first connecting means to compensate for wear of said brake pads.
Claim 8
Dependent Claim
24 words
The roller skate brake of claim 6 wherein said means for adjusting an effective length of said first connecting means is a rotatable thumbscrew.
