  • Patent number: 9010771
    Abstract: An apparatus for transporting carts including a machine body, a steering control arranged on the body, a steering pedestal pivotally arranged with respect to the body, and a selection mechanism adapted to be selectively coupleable between the body and the steering pedestal providing for a caster mode and a steering mode respectively. A method of using a dual mode utility machine including depressing a first lever thereby engaging a pivoting selector into a steering pedestal engaging position and controlling the direction of the machine by rotatably manipulating a tiller, and depressing a second lever thereby disengaging the pivoting selector from a steering pedestal engaging position to a body engaging position and controlling the direction of the machine by pushing and/or pulling a machine from side to side via a fixed tiller.

  • Patent number: 7533742
    Abstract: The present invention is a powered hospital bed mover or bed transfer system. The bed mover includes a bed attachment mechanism that is vertically displaceable relative to a base that includes an electrically powered drive wheel and a pair of support castors. The attachment mechanism includes a pair of horizontally oriented jaws with jaw openings that face away from each other. Each jaw includes a contact switch in its bottom surface and a contact switch in its jaw opening. The contact switches indicate to the mover and its user that the mover is properly engaged with the frame of a hospital bed. The jaws are horizontally displaceable and diverge from each other to engage vertical frame members of a hospital bed. A control panel has a joystick adapted to control the speed and direction of travel for the mover. The control panel also has controls for actuating the jaws, changing the elevation of the attachment mechanism, and locking at least one of the support castors.
