Abstract
A collapsible wheelbarrow has two side sections each of which has a generally rectangular load-containing wall, the two walls being hinged together about their lower edges. A tube projects forwardly from each wall to serve as a wheel support, and rearwardly to serve as a handle. A triangular front wall is pivoted to the two walls, the front wall being in two parts which are hinged together. The wheelbarrow may be opened out for normal use, or may be folded so as to be substantially flat, for storage or transport.
