Abstract
A braking system for in-line roller skates includes a hand-held brake actuator coupled to a plurality of brake assemblies by a conduit system. The brake assemblies are mounted on a housing beneath the boot portion of the roller skate adjacent selected ones of the rollers. The conduit system supplies hydraulic fluid to the brake assemblies which apply frictional pressure to the side walls of the rollers thus stopping the skates.
Claims18
A braking system for a pair of in-line roller skates, each roller skate including a plurality of rollers situated one behind the other along a line of directional travel of the skate comprising:
- a. a single hand operated actuator;
- b. a hydraulic conduit system coupling the actuator to each of said pair of roller skates, said conduit system including a coupling comprising an input from said actuator and two hydraulic output lines;
- and
- c. at least one hydraulic brake assembly located on each of said roller skates and coupled to each respective one of said hydraulic output lines for applying braking force to at least one of said rollers on each of said roller skates simultaneously.
In a roller skate, the roller skate including at least one roller having a sidewall and mounted in a housing on an axial shaft extending through the housing, a hydraulic brake comprising:
- (a) a hydraulic cylinder and piston mounted on said housing;
- and
- (b) a brake pad comprising a semi-flexible member extending between the piston and said sidewall of the roller and bearing against said sidewall in response to pressure from said piston.
In a pair of in-line roller skates, each skate having a first plurality of rollers arranged in a single straight line, a braking system including a single hand-held brake actuator coupled in parallel to a pair of brake assemblies, one such brake assembly for selected ones of said first plurality of rollers on each skate, wherein each of said brake assemblies are actuated simultaneously by said hand-held brake actuator.
