ABSTRACT:
A heat dissipating skateboard wheel assembly on which an elongate cylindrical tire formed from an elastomeric material is so supported that when the tire is subjected to axially directed forces of substantial magnitude, the end portions of the tire will not tend to cold flow, but will instead temporarily deform into circular confined spaces defined on the assembly. The external surface of the tire preferably has circumferentially and axially spaced grooves extending thereinto, with the grooves cooperating to define a number of independently deformable islands therebetween. The islands, as they sequentially roll into pressure contact with a flat supporting surface deform three-dimensionally due to the combined weight of the skateboard and user to which they are subjected. The islands, as they so deform, are forced into maximum surface frictional contact with the supporting surface, and the skateboard is accordingly less inclined to slip laterally when the user of the skateboard is negotiating a sharp curve. Substantially the entire interior surface of the tire is maintained in a true cylindrical configuration when the assembly is in use, and accordingly the outer end portion of the tire cannot deform to a distinctive non-circular transverse cross section as occurs when present-day skateboard wheel assemblies are used. Due to the major portion of the present skateboard wheel assembly invention being formed from metal, the heat arising from friction during the use of the invention is transferred to the metal portion where it radiates to the ambient atmosphere rather than being transferred to the elastomeric tire that forms a part of the invention.
