<p>A wheel (50) includes a generally cylindrical tire (51) having a plurality of spaced grooves (55) formed therein to define interleaved ribs (65). A hub recess (60) extends inwardly from the outer portion of the wheel to an interior face (52) which supports the tire and wheel. The wheel connector (70) having parallel sides and a bottom surface joined to the inner face of the supporting face combines with a front face to form a receptacle (14). The front face of the wheel connector defines a slot and slightly enlarged cylindrical portion for receiving a standard flange (31) and spacer (14) of a snap-fit connector (16).</p> |
