The four frame sections are pivotally connected with a plurality of rods so as to allow two collapsible frame sections to be folded inward. The flat boards which fit properly to the interior of the side frame, help keep the trolley sturdy when the side frame is fully extended for use. When the trolley is not in use, the flat boards are lifted from their normal positions and allowed to stand against the non-collapsible frame sections while the two collapsible frame sections are pushed inward.
