ABSTRACT:
A braking system for in-line skates that uses a cable-pulley system. The device uses a closed loop of cable that is placed over pulleys on the skate wheels. In between each wheel set is a pair of lever arms. Each lever arm has a pair of grooves. The cable loop corresponding to a particular lever arm fits into the pair of grooves in the lever arm. To activate the brake, the rider allows the brake skate to go ahead of the other skate. This action causes the cuff of the boot to pivot and push down on the heel lever, which causes the sliding plate to move forward or backward (depending on whether the skater is skating forward or backward). This movement causes the lever arms to pitch forward (or backward), causing the cable loops to tighten against the pulleys, thereby creating a braking action. Braking action can be done in either a forward or reverse direction. This design has a minimal number of parts, has a low maintenance operation, uses inexpensive components, can be quickly assembled, has long brake life, has braking for all four wheels, has either forward or reverse cuff actuation, and has easy and fast interchangeability of skate components.
