Abstract
Abstract This invention provides for a skate wheel structure including an outer arcuate shell (1) molded to an inner barrel (2). The outer arcuate shell (1) includes a series of spaced apart arcuate shell segments (20) which are joined each to the other by bridge members (5). The bridge members (5) have a contour which provides for an upper recess (6) and an internal opening or groove (3) formed below the bridge element (5). A plastic tire (4) is molded into the recess (6) and the groove (3) for securing the plastic tire (4) to the outer arcuate shell (1).
