Cart Pusher, Mateable Carts, and Related Systems, Methods, and Devices

Abstract

Various embodiments herein relate to powered pusher devices configured to push wheeled objects from one location to another. Further embodiments relate to wheeled objects such as carts for transporting items from one location to another. Other embodiments relate to platform powered pushers that can be coupled to a family of various wheeled objects.

What is claimed is: 
     
         1 . A wheeled cart comprising:
 (a) a base;   (b) four swivel wheels, wherein each swivel wheel is disposed at a corner of the base; and   (c) a guide wheel assembly disposed at a substantially central location beneath the base and moveably coupled to the base, the guide wheel assembly comprising:
 (i) an assembly frame, wherein the assembly frame is configured to move between a deployed position and a retracted position; 
 (ii) two guide wheels rotatably coupled to the frame; and 
 (iii) a deployment plate coupled to the frame, wherein movement of the deployment plate between an unactuated position and an actuated position causes the guide wheel assembly to move between the retracted and deployed positions.
