Abstract: The present invention includes a modular component skate wheel particularly usable in connection with preferably an in-line skate boot. All of the components are interchangeable and the components in preferred embodiments include snap fit surfaces. Preferably, a three piece wheel with interchangeable tire, hub and stationary drum is included to allow the user to adapt the modular skate wheels to the intended purpose. The tires may contain at least one light source for purposes of illuminating the preferably clear, transparent (or translucent) tires. The removable inner hub may be adaptable to contain a two-bearing configuration similar to existing skate wheels for the lightweight skating and maneuverability, such as required for roller hockey or speed skating. A generator may be snapped into the inner hub and used as a means of power to illuminate a light source contained within the tire or located on the boot if a flashy appearance is desired.

Abstract: The improved light generating and emitting roller skate wheel assembly of the present invention includes a wheel axle assembly carried by and beneath the roller skate blade. Such wheel axle assembly includes wheel bearings which are disposed thereon. A wheel hub is mounted on the wheel axle assembly and supported by the wheel bearings for rotational movement relative thereto. A tire, preferably made of a clear polymer is disposed about the wheel hub assembly. The roller skate wheel carries a light emitting mechanism, such as a light emitting diode, for emitting visible light preferably through the clear, polyurethane elastomer tires, as used in certain preferred embodiments. The roller skate wheel carries an electrical light generator which is electrically connected to the light emitting diode or other light emitting mechanism for providing electric energy and for generating light therefrom. The details of these structures are described in greater detail hereinbelow.
