Abstract: A roller skate with in-line wheels employs a brake disc capable of applying variable resistance to the rotation of the rear wheel. A skater may activate the brake by elevating the toe of the skate bringing a lever arm that is mounted at the rear of the skate and oriented downward into contact with the road surface. This contact causes the lever-arm to rotate as toe is elevated. Rotation of the lever arm induces contact between the brake disc and the rotating rear wheel by forcing the disc inward toward the wheel. Rotation of the lever arm and inward movement of the brake disc is opposed by separate spring-type means which return the brake disc and lever-arm to a rest position when skate is level, enabling the rear wheel to spin freely.

Abstract: A roller skate with in-line wheels employs a pair of brake discs capable of applying variable resistance to the rotation of the rear wheel. A skater may activate the brake by elevating the toe of the skate bringing a lever arm that is mounted at the rear of the skate and oriented downward into contact with the road surface. This contact causes the lever-arm to rotate as the toe is elevated. Rotation of the lever arm induces contact between the brake discs and the rotating rear wheel by forcing discs inward toward the wheel. Rotation of the lever arm and inward movement of brake discs is opposed by a separate spring device which returns the brake discs and the lever arm to a rest position when the skate is level, enabling the rear wheel to spin freely.
