Patent ID: 7210747

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 said wheel to enhance the appearance of that wheel comprising: a support member having an annular base with an opening therein and a cone the extends outwardly from the base, said cone having a peripheral surface with a first inwardly projecting lip thereon, said base engaging and rotating with said wheel; a first disc having a peripheral surface with an annular groove located thereon and a first axial projection shaft with an outward extending annular rib, said first disc having a first plurality of radial slots therein that extend from adjacent the first axial projection shaft to a location adjacent the peripheral surface to define a first plurality of radial spokes, said annular groove receiving said first inwardly projecting lip to secure said first disc to said cone; and a second disc having a second annular axial projection shaft with a bore therein to receive said first annular rib on said first axial projection shaft on said first disc, said second annular axial projection shaft having an inwardly extending annular rib thereon, said first axial projection shaft initially flexing inward and said second annular projection shaft initially flexing outward on engagement of said inward annular rib with said outward annular rib as said second disc is moved toward said first disc and later reversing the flexing directions as the inward annular rib moves past the outward annular rib to be located on first axial projection shaft of said first disc to retain said second disc in radial alignment with said first disc, said second disc having a second plurality of radial openings thereon that extend from a location adjacent said annular axial projection shaft to a location adjacent a peripheral ring thereon to define a second plurality of radial spokes, said second disc being free to rotate on said axial projection shaft as said first disc rotates with said cone such that the transmission of light between the wheel and a viewer is interrupted by the first and second radial spokes on the first and second discs to provide an illusion that the wheel is rotating faster than actually is occurring.
