ABSTRACT:
The present invention provides a tire arranged to circumscribe a spheroidal construction set joint element of the type having multiple facets located around its periphery each having a joint opening located therein. A portion of the facets circumscribe the joint element around a diametric axis and are arranged in a particularly defined pattern. The tire comprises an annular rim having a width slightly greater than the facets and is fabricated from a yieldable material so that it can be easily stretched for installation onto the joint element. The inner side of the tire includes a plurality of planar engaging surfaces, each having substantially the same shape as the joint element facets, arranged in the same pattern as the circumscribing facets. Accordingly, when the tire is placed over the joint element, the engaging surfaces mate with the facets to prevent rotation of the tire relative to the joint element. Extending inwardly from each of the engaging surfaces is a protrusion which snugly fits within a joint opening when the tire is placed over the joint element, thereby further securing the tire to the joint element. Upstanding lugs, having beveled corners, are located around the outer periphery of the tire at spaced intervals. The lugs are rectangular in cross-section and are spaced apart by a distance which is slightly greater than their width thereby allowing the lugs to serve the dual function of tire tread and gear teeth. An annular ring formed on the outer edge of each side of the tire defines the tire and serves as a white sidewall.
