ABSTRACT:
A braking system for a pair of in-line roller skates having a housing with a plurality of rollers located one behind the other along a line of directional travel of the skate from a front end to a rear end. First and second rotors are secured to at least one of the plurality of the rollers. First and second pistons retained in the housing are located in a line perpendicular to the first and second rotors. An actuation piston is located in the housing and connected by first and second passageways to the first and second pistons. A boot which is secured to the housing has a pivotally attached collar located adjacent an opening for the foot of a skater. The collar engages an ankle of a skater for retention of the boot on a foot of the skater. A linkage extends from the collar to the actuation piston. When the skater is traveling in a forward direction, a center of gravity through which weight is transmitted from the boot into the housing is located toward the front end of the housing. This center of center of gravity is shifted from the front end toward the rear end of the housing by the skater moving toward an erect position. As the skater moves toward the erect position, the collar pivots with respect to the boot to provide the linkage with an input force which moves the actuation piston in the housing. Movement of the actuation piston in the housing creates a hydraulic pressure which is simultaneously supplied to move the first and second pistons into engagement with the first and second rotors to brake the roller.
