  • Patent number: 4236723
    Abstract: The invention disclosed is a cart designed to carry a load and to be pulled behind a user when strapped to the user's waist or hips. Normally the cart contains a generally upright, adjustable-length load-support frame. A load-supporting means supports the load on the frame. A pair of wheels is attached to the distal end of the frame, and a pair of rigid, generally horizontal arms extends from the frame's proximal end out toward the user at an adjustable angle. A means for attaching the cart to the user's waist, preferably a strap, is located at the proximal end of the arms.In operation, a piece of luggage or other load is placed on the cart's frame and supported there by the load-supporting means which is usually a platform-like structure. The strapping means is then strapped to the user's lower torso so that the cart is positioned behind the user, its wheels resting directly on the ground. The user can then tow the load and cart behind him by walking or even running forward.
