Abstract
A cart has a collapsible frame which is foldable into a closed position for forming a narrow lateral profile and unfoldable into an unfolded open position. The frame has two support members. Each support member has a pair of legs extending downwardly from its opposite ends and a side arm extending between two of the legs on each opposite lateral side of the frame for securing the frame in the unfolded open position with the support members spaced apart. The side arms have hinges for folding the arms relative to a support member. A foldable tray interconnects the legs of the frame for forming a platform adjacent the bottom of the cart. Upon folding of the cart, the tray folds and the cart collapses into the closed position with the support members drawn together into close proximity to each other.
