Abstract:
A drive mechanism is provided for a door operator, comprising a drive member and a driven member. The drive member includes a protrusion, the edges of the protrusion forming first and second driving surfaces which define a free space of at least about 90° there between. The driven member includes a protrusion, the sides of the protrusion form a first and a second driven surface, respectively. The drive member is adapted to be operably connected to between a motor assembly for rotating the drive member and a door closer assembly rotating with the driven member. The drive member and the driven member are disposed for relative rotation in substantially the same plane such that the driven member protrusion moves in the free space defined by the driving surfaces of the drive member protrusion. Rotation of the drive member from a first angular orientation to a second angular orientation in a direction toward an adjacent driven surface causes rotation of the driven member for powered opening of the door from the closed position to the open position. The driven member protrusion moves in the free space without engaging the protrusion surfaces when the door is opened manually from the closed position and allowed to close.

Abstract:
A power drive assembly moves a liftgate (12) of a motor vehicle (10) between its open and closed positions. The motor vehicle (10) defines an opening and the liftgate (12) closes the opening when the liftgate (12) is in its closed position. The power drive assembly (22) includes a base (24) that is fixedly secured to the motor vehicle (10) at a position in spaced relation to the opening. A drive mechanism (38) is fixedly secured to the guide. The drive mechanism (38) converts electrical energy into a linear force. The power drive assembly (22) includes a translation linkage (58) connected to the drive mechanism (38) for receiving the linear force and translating it into a nonlinear force to move the liftgate (12) between the open position and the closed position. A nut (52), secured to the translation linkage (58), moves the translation linkage (58) as it travels along a lead screw (50) that is rotated by a motor (40).
