A folding shopping cart, laundry cart or the like in which a generally box-shaped fabric sack serves as an essential structural integer for holding two rigid generally horizontal upper side members of the cart in parallel relationship a given distance apart against forces developed upon unfolding the cart which would otherwise spread the upper side members further apart. The back and the bottom of the cart have respective cross frames of centrally pivoted rigid members, while the front of the cart has a parallel spaced pair of rigid vertical side members. The cart is locked into its unfolded condition by a knuckle-jointed cross brace between the lower ends of back cross frame. The rigid members of the cart are so interconnected that the cart folds into a stick-like bundle which includes wheels provided at the four corners of the bottom cross frame and a pair of rigid handle members articulated to the rear ends of the upper side members. |
