ABSTRACT:
A braking system is provided for an in-line roller skate for skating on hard skate-supporting surfaces. The roller skate includes a shoe, a wheel-supporting frame attached to the shoe, and a plurality of aligned wheels operably supported by the wheel-supporting frame. The braking system includes an extension connected to the wheel-supporting frame including a pair of opposing flanges, a brake pad operably supported on the extension, and a braking wheel positioned generally in alignment with and behind the plurality of aligned wheels. The braking system further includes an axle rotatably supporting the braking wheel. The axle is supported on the extension by a support mechanism for sliding movement between various braking positions such that, as the braking wheel engages the hard surface with increasing force, the braking wheel moves toward the braking pad and generates increasing braking force. Various support mechanisms for slideably supporting the braking wheel are disclosed.
