ABSTRACT:
A multi directional wheel, particularly for use with guide structures and conveying structures, driven or undriven, consists of only two different parts, namely an integral one piece molded synthetic resin hub and an integral one piece molded synthetic resin roller. A plurality of such rollers are mounted about the periphery of the hub so that the axes of the rollers are parallel to each other and perpendicular to the axis of the hub, with bearings being provided by the inherent structure of the hub and rollers. Bearing supports extend outwardly from the hub and engage between subrollers that make up the rollers, so that the rollers may be closely spaced to each other without any intervening structure, to lessen flat spots between adjacent rollers. Rollers are snap fit into the bearing supports in the axial direction, so that two wheels may be mounted together as mirror images to prevent withdrawal of the rollers on the snap fit assembly. In such an assembly, the rollers, bearing barrel shape, may be angularly offset as between adjacent wheels and overlap a central plane of symmetry. A plurality of teeth are mounted between annular flanges of the hub to reinforce the hub immediately opposite each roller and to provide for toothed driving of the hub.
