Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
215 words
An improved light generating and emitting roller skate wheel for use upon a roller skate to enhance the visibility of a roller skater in conditions of darkness comprising: a wheel axle assembly carried by and beneath the roller skate; said wheel axle assembly including wheel bearings disposed thereon; a wheel hub mounted on said wheel axle assembly and supported by said wheel bearings for rotational movement relative thereto, said wheel hub having an outer radial surface and a plurality of recessed portions with openings formed in said radial surface; a substantially transparent tire having an inner radial surface mounted on said outer radial surface of said wheel hub, said inner radial surface having a circumferentially extending recessed portion formed therein overlying said openings formed in said radial surface of said hub; said wheel hub carrying radially outwardly directed light emitting means within each of said recessed portions for emitting visible light through said openings formed in said radial surface of said hub and through said substantially transparent tire for permitting said light to be observed from behind and from in front of the roller skater to enhance visual detection thereof; and said roller skate wheel carrying electric generating means electrically connected to said light emitting means for providing electrical energy to said light emitting means.
Claim 2
Dependent Claim
215 words
An improved light generating and emitting roller skate wheel for use upon a roller skate to enhance the visibility of a roller skater in conditions of darkness comprising: a wheel axle assembly carried by and beneath the roller skate; said wheel axle assembly including wheel bearings disposed thereon; a wheel hub mounted on said wheel axle assembly and supported by said wheel bearings for rotational movement relative thereto, said wheel hub having an outer radial surface and a plurality of recessed portions with openings formed in said radial surface; a substantially transparent tire having an inner radial surface mounted on said outer radial surface of said wheel hub, said inner radial surface having a circumferentially extending recessed portion formed therein overlying said openings formed in said radial surface of said hub; said wheel hub carrying radially outwardly directed light emitting means within each of said recessed portions for emitting visible light through said openings formed in said radial surface of said hub and through said substantially transparent tire for permitting said light to be observed from behind and from in front of the roller skater to enhance visual detection thereof; and said roller skate wheel carrying electric generating means electrically connected to said light emitting means for providing electrical energy to said light emitting means.
