Abstract
Abstract A skateboard hubcap for protecting the wheel bearings of a skateboard from environmental contamination, such as dirt, sand, and water. The invention also enhances the general appearance of the skateboard by concealing the axle nut and bearings. The skateboard hubcap comprises a shield which covers the normally exposed wheel bearings, an axle receiving column which slides over the axle nut, and detents on the inner flat surfaces of the substantially cylindrical extension to secure the skateboard hubcap on place. A spacer is placed behind the axle nut to assure adequate clearance for the detents to lock onto the axle nut.

Claim 1
Independent Claim
183 words
A skateboard assembly for covering a normally exposed axle nut and wheel bearings of a skateboard wheel comprising: (a) a shield sized to cover the exposed skateboard axle nut and wheel bearings; (b) an axle receiving column, said axle receiving column being hexagonal in cross-sectional shape and connected to a first side of said shield and extending therefrom, said column having a central cavity, the inner surface of said cavity being formed for mating engagement about the axle nut; (c) a cylindrical strip connected to the first side of said first shield and extending therefrom, said cylindrical stop being affected to limit the axial movement of said shield toward the axle nut; (d) at least one dentent formed on said cavity inner surface for locking said axle receiving column in place about the axle nut to limit the axial movement of said shield away from the axle nut; and (e) a spacer disposed intermediate the axle nut and the wheel bearings, said spacer having an outer diameter less than that of the axle nut, for providing a relief region for receiving said dentent.
