ABSTRACT:
A foldable dolly in which the arms are rotatably mounted to the frame preferably by means of interengaging sleeves formed with opposed ramps and opposed shoulders and positioned in relatively vertical alignment such that the ramps and shoulders of the first sleeve mate with the ramps and shoulders of the second sleeve. The sleeves are thereby found to permit rotation of the arms between a folded, collapsed position and an extended deployed position, while at the same time providing enhanced rigidity and stability of the arms at the extended, deployed position.
