Abstract
A folding wheelbarrow can be constructed so as to utilize a wheelbarrow body which is adapted to be folded or manipulated from a normal position into a folded position. Such a body is attached to a wheel support serving to carry a normal wheel and handles. In order to achieve a satisfactory folding action each such body is constructed so as to have a bottom wall including at least two bottom panels, a front wall having at least two front wall panels and sides connected by the bottom wall panel and the front wall panel. A plurality of separate linkage hinges connect the bottom and front wall panels and the sides so as to permit Sarrus-type motion of the panels and the sides during manipulation of the body from a normal position into a folded position. A latch or latch-type structure is preferably used to connect at least two parts which pivot relative to one another during such folding so as to hold the body in its normal position.
