Abstract
Abstract A cart has an L-shaped main frame with triangular sides along the shorter side of the frame and a handle extending transversely across the cart at the extremity of the longer end. An axle at the corner where the two ends of the frame meet supports large ground wheels on either side. There are casters adjacent the extremities of both ends and handles immediately inside and slightly below the casters. The cart accepts large cabinets, such as television and hi-fi sets, as well as smaller objects, and enables one man to load and unload the sets, move the load up and down stairs and onto the beds of trucks and negotiate abrupt turns in narrow passageways.
