发明名称 Powered utility cart having engagement adapters
摘要 The present inventive device generally allows a user to easily engage and push or pull heavy and unwieldy object(s), most notably a line of nested shopping carts, effectively and without undue strain. The cart is designed specifically with universal utility in mind. The power is supplied by either an electrically driven motor or internal combustion engine. Power is transmitted to a transaxle with belts or an electric motor electronically controlled. A simple forward/reverse control via throttle handles causes cart movement and steering is achieved through dual rear castors. The front of the cart contains a receiver that allows easy attachment for a multitude of attachments for a variety of uses. A square tube fitment with a quick release device lets the cart be configured for different markets and easy field change. One such attachment is a shopping cart adapter, which attaches to the cart through the receiver connection. It has two quick connect devices that attach to the rear of most available shopping carts. It has a center pivot that facilitates steering and positioning one or several carts.
