  • Patent number: 6098216
    Abstract: A convertible patient transport apparatus includes a frame assembly adapted for supporting a patient. A plurality of bent pivot legs are attached to the frame assembly and mounted on respective wheels for rolling movement of the transport apparatus over a supporting surface. Each of the pivot legs includes a vertical upper portion, an intermediate portion formed at an angle to the upper portion, and a vertical lower portion formed with the intermediate portion. An actuator pivots the legs between an open position, wherein the distance between the lower portions of laterally adjacent legs is increased, and a closed position, wherein the distance between the lower portions of laterally adjacent legs is reduced. In the open position, the width of the transport apparatus is expanded to move the frame assembly over a bed of the patient. In the closed position, the width of the transport apparatus is narrowed.
