Patent ID: 7387303

Claim:
In a roller skate having an axle with a bearing and wheel retained thereon by a nut such that the wheel freely rotates on the axle, a spinner apparatus secured to the wheel to enhance the appearance of the wheel comprising: a support member having an annular base with an axial opening therein, a first plurality of radial slots therein the extend from a first location adjacent said axial opening to a second location adjacent a peripheral surface and first and second axial legs that extend from the annular base with the first axial leg having a first radial opening adjacent a first end thereof and the second axial leg having a second radial opening adjacent a second end thereof, said first leg and said second leg extending through corresponding axial openings in the hub of the wheel; a clip having a first end located in said first radial opening in said first leg and a second end located in said second radial opening in said second leg; a spring located between the bearing and said annular base to position said annular base adjacent an outer face of the wheel; and a disc having a second plurality of radial slots therein that extend from a first location adjacent a center axial projection to a second location adjacent its peripheral surface, said center axial projection having a radial slot that extends from an end thereon toward the disc, said center axial projection having a groove located between said end and said disc such that on insertion of said center axial projection into said axial opening in said support member said annular base is positioned in said groove, said disc being free to rotate with respect to said support member while said support member rotates with the wheel to interrupt the transmission of light between the wheel and a viewer through the first and second plurality of radial slots to illustrate a difference in the rotation of the wheel with respect to the disc.
