  • Patent number: 4592595
    Abstract: A wheel construction especially adapted for use with a shopping cart and the like, including a wheel of a first relatively inexpensive material comprising a central hub defining a central opening providing an axis of rotation for the wheel, a rim, and web means connecting the rim and hub. The rim defines an outermost peripheral surface and adjoining surfaces merging into the peripheral surface. Further said rim defines a plurality of circumferentially spaced notches, each of the notches extending generally laterally of the rim and inwardly of the peripheral surface toward said hub, and providing undercuts. A generally U-shaped tread member of a second material, such as relatively more expensive polyurethane rubber, is molded to the rim.
