ABSTRACT:
A multi-purpose hand truck having an elongated frame (1) possessing at one end two wheels (9) as well as toe plate (7) projecting at approximately 90.degree. from the frame, and at the other end possessing a handle arrangement (3); in a further refinement the truck can be converted into a utility table by means of a table top (10) and a support stand (5) which are attached to the frame (1). The table top (10) is on the one hand preferentially pivotably attached to the support stand (5) and on the other hand it pivots and is guided longitudinally in the side members (2) of the frame (1). For this purpose trunnions (14) projecting transversely from the table top (10) engage in grooves (15) on the inner surfaces of the side members (2). When the table top (10) is folded out, the toe plate (7) can be pivoted through the frame (1) into a horizontal position (7") so that its underside faces upwards.
