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.
摘要翻译：用于模制轮的模制轴承组件包括嵌入模制轮的毂中的合成树脂外轴承座圈，并具有圆柱形的内滑动轴颈类型的支承表面。内轴承组件包括两个模制合成树脂轴承半部，其具有设置在外轴承座内的连续圆柱形外轴承表面，与外座圈的内支承表面滑动接合。内轴承组件的轴承半部在其内端处彼此抵接，并且可以包括在其内端处的互锁结构特征，其能够使轴承半部在其内端处固定在一起，同时具有连续的外圆柱形轴承滑动表面，其与外圈的相邻表面。轮轴延伸穿过内部轴承组件并且支撑车轮和轴承组件以相对于车轮支撑件旋转。模制轮和轴承组件适于与购物车一起使用。

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.
