Abstract
Abstract A brake for a roller skate that prevents rolling backward comprising a pair of rollers (37) eccentrically mounted on an axle (36) and positioned immediately adjacent the front wheels (17) so as to allow forward rotation but to bind against and brake the wheel when the wheel initiates backward rotation.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
196 words
A brake for a roller skate with a shoe having fixed thereto a truck assembly supporting an axle on which is mounted two parallel positioned wheels capable of rotating in the forward and reverse directions and the axle is supported to turn when the shoe is tilted relative to the truck assembly wheels, said brake comprising: a shaft; a roller eccentrically mounted on each end of said shaft to include radial sections having large and small radii; means mounting said shaft on said skate with each of said rollers having a small radius section abutting one of said wheels peripheries and positioned to be rotated to bring a large radius section into contact with its respective wheel when the wheels are rotated in the reverse direction to thereby increase the contact pressure between each wheel and its respective roller; said means mounting said shaft including a bracket fixed to tilt and turn the roller with the axle so as to maintain equal roller pressure on the wheels of the truck assembly; and means stopping rotation of said roller so the roller will brake rotation of the wheel when the wheel is rotated in the reverse direction.

Claim 3
Dependent Claim
22 words
A brake as defined in claim 1 including means to releasably hold said roller out of contact with said wheel when deactivated.
