Abstract
An improved versatile cart (20) structure is the subject of this invention. The cart (20) has a lower frame structure (20) for supporting bulky objects, a pair of spaced upright supports (30) extending from the lower frame (22) and an upper frame structure (30.1a) extending rearwardly from the upright support (30) and over the lower frame (22) in spaced relationship, for carrying objects and also forming a guide handle (32) for the cart (20). In preferred form, the cart (20) is configured for nesting engagement with similarly styled carts and for use for automatic cart vending systems. A unique wheel structure supports the cart (20) in a manner that enables stable positioning of the cart (20) on escalators. In one configuration, the cart (20) forms a luggage carrier having a child seat convertible to an adult seat for use as a temporary wheelchair.
