  • Patent number: 4300781
    Abstract: A variable, easily actuated braking system for roller skates. A fixture carrying a hinged brake pad support is mounted on a conventional roller skate with the pads movable between a spring-assisted disengaged position and a sleeve and cable actuated engaged position. The cable is attached to the hinged support and the sleeve end to the fixture. Inner and outer actuator rings are attached to the other ends of the cable and sleeve, respectively. When the sides of the rings away from the attachment points are manually squeezed together, the pads are brought into braking engagement with the wheels. Strap means are provided for holding the ring actuators in easily reached positions along the outer upper thighs of the wearer. A self-aligning attachment is provided between the cable end and the brake pads to assure uniform, even braking.
