    Abstract: A power actuator for lifting a pivotal lift gate closing an access opening in a motor vehicle body. The actuator includes a lower tubular housing; a lead screw having a lower head portion journaled in a lower portion of the tubular housing and a threaded shaft portion extending upwardly from the head portion within the tubular housing; a tubular extender rod positioned slidably and telescopically within the tubular housing in concentric surrounding relation to the shaft portion of the lead screw and including a nut structure proximate a lower end thereof threadably engaging the shaft portion of the lead screw; a pivotal mounting structure on the lower end of the tubular housing to pivotally mount the lower end of the tubular housing to a side edge of the access opening; a pivotal mounting structure on the upper end of the tubular extender rod for pivotally mounting the extender rod to the lift gate; an electric motor positioned on the motor vehicle body proximate the access opening; and a flexible cable extending from the output of the motor and passing through an aperture in the lower end of the tubular housing for driving engagement with the head portion of the lead screw. The cable is mounted for rotation about a lengthwise axis of the cable whereby actuation of the motor moves the tubular extender rod axially relative to the tubular housing and provides opening or closing movement of the gate.

    Abstract: A door closer (20) is attachable to a door (24) and is formed with a chamber (44) in which a piston element (50) is movable to move fluid from the chamber to a reservoir (82) upon opening of the door. After the door (24) has been opened to a position, for example, of sixty to seventy-five degrees, continued opening of the door causes the fluid to be compressed within the chamber (44) and to be directed only through a back check valve (95) to the reservoir (82). This results in the development of an adjustable "back check" condition to provide a counterforce to the continued opening of the door. The adjustable valve (95) includes a spring biased ball (144), the biasing of which must be overcome by the force of the fluid being compressed in the chamber (44) to allow for fluid to pass through the valve to the reservoir (82).The chamber (44) is formed partially by a spring tube (38) having slots (192) formed in the interior wall thereof which extends radially beyond convolutions of spring (52) contained within the tube. The slots (192) allow the fluid, and gas bubbles entrapped therein, to be moved beyond the convolutions of the spring (52) and to be moved unimpeded into the reservoir (82). Otherwise, the gas bubbles would be trapped in the chamber (44) and would deleteriously affect the operation of the door closer (20).

    Abstract: A door operator of electromechanical character for utilization with pivotally mounted doors, as by a center pivot, a butt hinge, or an offset pivot, comprising a prime mover, a driving shaft, adapted for rotation about a vertical axis and being secured through an arm to the door to be operated. A gear train interconnects said prime mover and said driving shaft wherein the gears are mounted as by a unique arrangement of needle roller and needle thrust bearings to permit said gear train to operate smoothly in door opening operation as a speed reducer and in door closing operation as a gear increaser. Energy storing means operatively connected to said driving shaft for storing energy during door opening operation and for energy releasing to drive said gear shaft during door closing operation. The said operator is adapted for compact disposition within the header of a door frame.

    Abstract: The invention concerns a drive unit for moving a door relative to a door's opening. The drive unit comprises a drive motor and a wheel transmission assembly arranged for transfer of power to a drive wheel configured for engagement with a running surface for moving the door. The wheel transmission comprises a transfer wheel driven by the drive motor. A movable wheel carrier comprises a first running wheel and a second running wheel arranged in in engagement with the transfer wheel. The movable wheel carrier is arranged for displacement between a free wheel position where the first and second running wheel are arranged disengaged from the drive wheel for no power transfer to occur from the drive motor to the drive wheel, at least one running position where either of the first and second running wheel is positioned in engagement with the drive wheel for the transfer of power from the drive motor to the drive wheel.
