ABSTRACT:
A fold-up wheelbarrow comprises a wheel and two elongate frame members connected pivotally to the wheel by hinges. A pair of legs and a flexible, load-bearing body depend from the frame members. The load-bearing body is comprised of a plurality of sheet-like panels made of a flexible material such as canvas or plastic. The wheelbarrow is held open by locking bars that help to stabilize the frame members. When the wheelbarrow is in its open position, the frame members are biased away from each other.
