Abstract:

A improved wheeled hand cart assembly incorporates a tiltable lifting platform associated with a trailing platform that together permit transporting interchangeable loads on the lifting platform together with other, relatively heavy, fixed loads on the trailing platform. The cart assembly incorporates a lifting cart structure of generally L-shaped configuration wherein the short leg of said L-shape acts as a lifting platform and the longer leg of the L-shape serves generally as the handle portion of the cart in conventional manner. A pair of axially spaced-apart wheels are rotatably mounted on a substantially common axis on the lifting cart, close to the juncture of the longer leg and the short leg, so that the lifting cart may be rolled from place to place on the floor or ground. The lifting cart structure is tiltable about the common axis of the two wheels to retain a load within the angle formed by the juncture of the longer leg and the short leg. The improvement resides in a trailing cart structure comprising a support platform member having a forward end portion coupled to the lifting cart structure for pivoting about an axis substantially parallel to the common axis of the wheels, and a rearward end portion supported on a caster-like wheel assembly for rolling from place to place in coordination with the spaced-apart wheels.
