ABSTRACT:
A multi-purpose, movable apparatus (henceforth dolly-truck) for conveying objects, such as, for example, a five-gallon cylindrical industrial bucket is described. The dolly-truck includes a one-piece, molded plastic base having caster wheels and truck wheels. The caster wheels are mounted on a lower surface of the base and provide short distance rolling movement capability in the upright position. Connected to the base are two truck support arms which support an axle with two truck wheels. The truck wheels provide a hand truck capability for negotiating stairs, bypassing obstacles and an omnidirectional capability in conveyance of objects. Centered on the base is a retaining wall for receiving and holding objects. Connected to, and integrated into the retaining wall is an adjustable handle for conveying the dolly-truck by hand. The handle can be used to move the dolly-truck on the caster wheels as a conventional dolly, or alternatively on the truck wheels as a conventional hand truck. The base of the dolly-truck is surrounded by an optional ring which allows the dolly-truck to be conveyed by foot. An annular surface of the base outside the retaining wall and inside the ring forms a spill surface that prevents spillage of liquid from an open bucket onto the floor.
