Abstract
Abstract A utility cart of being hand-drawn over either soft or hard ground and of carrying loads of varying size and weight. The cart is composed of two distinct sections which may be dismantled when not in use to provide a more compact structure for storage or shipping purposes. The first or truck section is constituted by a frame having an axle carrying a pair of wheels, each wheel having a center tire which is flanked on either side by rollers having a paddle-wheel formation. The second section is constituted by a cradle which is supported on the truck frame, the cradle having both a handle and a rest pivoted on one end thereof.
