Abstract:
A skate wheel comprising:a generally cylindrical hub having an axially extending axle opening, said hub further having first and second axial ends separated by a cylindrical surface;an outer layer of a first synthetic plastic material having a first density;an inner layer of a second synthetic plastic material having a second density less than said first density, said inner layer being generally centrally positioned surrounding said cylindrical surface and spaced from said axial ends;first and second anchors projecting radially outward from said hub and extending circumferentially about said hub, said first and second anchors being disposed in axially spaced-apart relation, said first and second anchors and said cylindrical surface defining an outwardly opening central channel, said channel sized to receive said inner layer with said inner layer being retained in said channel; andsaid first material surrounding said inner layer on at least radially outer and axially outer surfaces of said inner layer with said first material molded onto said hub and surrounding said cylindrical surface such that said first material and said cylindrical surface encapsulate said inner layer, an outer surface of said first material having a progressively increasing radial dimension from said axial ends toward a center of said hub.
