摘要： A modular, universal, molded plastic flatbed type cart for carrying and supporting products includes variable product supporting metallic handles located at opposed ends of the cart. The handles include vertically extending posts that define at least one central channel completely open in an upward direction above the bed section of the cart and preferably another upwardly opening side channel located above the cart bed; continuous U-shaped handles, handles with a collapsible tray, and connector rails spanning the handles from one end of the cart to the other. The product handles are usable for manipulating the cart and are integrated into metal cart bed reinforcing elements.

摘要： A molded bearing assembly for a molded wheel includes a synthetic resin outer bearing race element embedded in the hub of the molded wheel and having a cylindrical inner sliding, journal type bearing surface. An inner bearing assembly includes two molded synthetic resin bearing halves having continuous cylindrical outer bearing surfaces disposed within the outer bearing race in sliding engagement with the inner bearing surface of the outer race. The bearing halves of the inner bearing assembly abut each other at their inner ends and may include interlocking structural features at their inner ends that enable securing of the bearing halves together at their inner ends while presenting a continuous outer cylindrical bearing sliding surface that cooperates with the adjacent surface of the outer race. A wheel axle extends through the inner bearing assembly and supports the wheel and bearing assembly for rotation relative to a wheel support. The molded wheel and bearing assembly is adapted for use with a shopping cart.

摘要： A transport and display cart is formed of light weight plastic and metal components including a base unit formed from an open framework in which is disposed and fastened a molded plastic tray. Wheels preferably including casters are provided on the underside of the base unit and opposed ladder units having horizontal bars or rungs are removably connected to opposed ends of the base unit by fitting within post supports rigidly connected to the base unit. Upper shelves include plastic trays that are constructed identical to the tray connected to the base unit and reinforcing rods having downwardly open jaws or hooks at their opposed ends for engaging the horizontal rungs or bars of the opposed ladder units. The upper shelves can be selectively disposed in horizontal or tilted positions simply by hooking the ends of the reinforcing rods over different rungs of the ladder units.
