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.

摘要： A plastic basket of a nestable shopping cart is integrally formed with support projections at upper inner edge portions of the side panels thereof at a position spaced rearward of a front panel. The support projections are adapted to support a pivoting rear gate member of a similarly constructed cart such that, when the two carts are nested, the rear gate panel abuts and is supported by the support projections in order to prevent the rear gate panel from dropping down into the plastic basket during cart nesting.

The frame includes a pair of substantially parallel longitudinal side members and a pair of substantially parallel transverse side members which form a generally rectangular frame having corners. A bottom of the dolly is at least partially formed in a honeycomb/cellular configuration. A plurality of casters are mounted to the bottom of the frame via a plurality of caster fastening bolts which are received in a corresponding plurality of caster fastening holes disposed at the corners. The dolly may also include a riser block disposed on a top of the frame along a side member and secured to the frame by the caster fastening bolts. A rubber pad may be disposed on the riser block and secured between the riser block and the top of the frame. The dolly may also include a channel in the bottom of one or more side members for receiving a reinforcing member.

摘要： A platform type hand cart includes a molded resin load carrying bed that is universally adaptable for both nesting and non-nesting cart configurations. The cart bed is slightly tapered from its rearward end to its forward end to enhance nestability, has a downwardly and forwardly sloping rear edge to further enhance nestability and includes various groups of mounting pads integrally molded into the underside of the bed for receiving fasteners used to secure wheel assemblies, a hinge assembly and a bumper assembly. Integrally molded reinforcing rod receiving pads may also be integrally molded into the underside of the bed for receiving structural reinforcing rods to stiffen the bed against deflection under load. By providing a single bed member with all of the various mounting pads required for nesting and non-nesting cart configurations, economies are achieved by permitting use of a single mold to produce a single bed adaptable for nesting and non-nesting cart applications. The molded bed is further provided with a protective rounded edge extending over at least a portion of the sides and the rear of the bed to protect feet and ankles of users of carts incorporating the bed member. The bed member includes mountings pads for assembling an elastomeric bumper to the forward end of the bed.
摘要翻译：平台式手推车包括可嵌套和非嵌套推车配置的普遍适用的模制树脂承载床。推车床从其后端到其前端略微渐缩以提高可嵌套性，具有向下且向前倾斜的后边缘以进一步增强可嵌套性，并且包括一整套模制到床的下侧中的各种安装垫，用于接收用于固定轮组件，铰链组件和保险杠组件。整体模制的加强杆接收垫也可以一体地模制到床的下侧中，用于接收结构增强杆，以加强床以防止在负载下的挠曲。通过为嵌套和非嵌套推车配置提供所有各种安装垫的单个床构件，通过允许使用单个模具来生产适合嵌套和非嵌套推车应用的单个床来实现经济。模制床还设置有保护性圆形边缘，其在床的至少一部分侧面和后部延伸，以保护包含床构件的推车的使用者的脚和脚踝。床构件包括用于将弹性保险杠组装到床的前端的安装垫。

摘要： A flat bed cart includes a molded resin load carrying bed having longitudinally spaced ends, a generally planar upper side and a bottom side that includes a plurality of ribs, a pair of spaced, longitudinally extending slots and first, second and third sets of integrally molded fastener mounted pads that are located adjacent the first and second ends of the bed and intermediate the ends respectively. The slots receive a pair of longitudinally extending reinforcing bars that carry at their ends upright handle receiving mounts. The handle receiving mounts include members arranged in recesses spaced about the periphery of the bed at the first and second ends thereof. At least one handle is provided which is adapted to be selectively positioned within a respective pair of the upstanding handle receiving mounts. The cart also includes first and second swiveling caster wheel assemblies mounted to the underside of the bed at each end thereof through a pair of support blocks that extend laterally across the bed and a pair of centrally mounted enlarged wheels about which the cart can be pivoted for maneuvering purposes.
