Mechanism for moving a heavy object.

摘要

A heavy object, such as a portable toilet (2), is supported on a base (1). At least one wheel (7) is mounted on the base (1) for vertical movement between an upper position in which the wheel (7) is supported above the lower surface of the base and a lower position in which at least a portion of the periphery of the wheel is below the lower surface of the base. The wheel (7) is releasably held in one or the other of those positions. A handle (6) is movably mounted on the object so that the object can be manually swung to permit the wheel to move between those positions.
