ABSTRACT:
A new and improved folding utility cart apparatus includes a vertical support assembly which includes a top portion adapted to serve as a handle, a middle portion, and a bottom portion. A pair of wheels are connected to the bottom portion of the vertical support assembly. A container support assembly is rotatably connected to the bottom portion of the vertical support assembly. A limit assembly is connected between the vertical support assembly and the container support assembly, for limiting rotation of the container support assembly around the bottom portion of the vertical support assembly. A container top guide assembly is rotatably supported by the middle portion of the vertical support assembly. The container top guide assembly includes a first lever arm portion, a fulcrum portion, a second lever arm portion, and a guide ring. A spring assembly is connected between the top portion of the vertical support assembly and the first lever arm portion of the container top guide assembly. The spring assembly is capable of exerting a clamping force between the guide ring assembly of the container top guide assembly and a top of a container. A locking assembly is selectively connected between the middle portion of the vertical support assembly and the first lever arm portion of the container top guide assembly. When not is use, the apparatus can be folded by folding the container support assembly up toward the vertical support assembly and by folding the guide ring assembly down toward the folded up container support assembly.
