Abstract
A collapsible utility cart apparatus (10) including a basket device (11) having a generally vertical first side wall second side wall (13, 13'"'"'), and spaced-apart support wheels (14, 15 and 14'"'"', 15'"'"') rotatably mounted to a bottom wall (12) of the basket device (10). A first and a second frame member (16, 16'"'"') are mounted to a respective side wall (13, 13'"'"') of the basket device (11) for pivotal movement of the frame members (16, 16'"'"') in a respective plane substantially parallel to and adjacent the side walls (13, 13'"'"') between a deployed position and a stored position. In the deployed position, the basket device (11) is vertically supported by the frame members (16, 16'"'"') to position the bottom wall (12) and the support wheels (14, 15 and 14'"'"', 15'"'"') off the ground a predetermined height. In the stored position, the respective frame members (16, 16'"'"') are positioned substantially adjacent the side walls (13, 13'"'"'), respectively, for storage.
