Abstract: A manual window regulator in which a pinion rotatably carried by a window glass and driven by a manual handle is held in engagement with a rack which is fixed to extend in the direction of movement of the window glass, so that a manual rotation of the handle causes the pinion to roll along the rack in meshing engagement therewith so as to drive the window glass thereby opening and closing a window. The transmission of rotation from the handle to the pinion is effected through a tape stretched between a drive gear rotationally driven by the handle and driven gear coaxially fixed to the pinion. The rack and the pinion are usable also as the parts of a power window regulator. The manual window regulator therefore can be easily converted into a power window regulator by using an electric motor for driving the pinion in place of the unit including the handle, the drive gear and the tape.

Abstract: A closure device for opening and closing an opening by moving a closure member substantially vertically has a motor for driving the closure member. The motor is secured to a lower portion of the closure member and within substantially the same plane as the plane of movement of the closure member. Accordingly, it is possible to prevent an eccentric load from being applied to the closure member.

Abstract: A power supplying system for supplying power to a self-driving closure device in which a driving source for driving the closure device for opening and closing an opening moves together with the closure device includes a lead wire having one end connected to a power source and the other end connected to the driving source. The side of the lead wire connected to the power source is supported at a midpoint between the positions of the upper and lower limits of movement of the driving source, while the side of the lead wire connected to the driving source is supported in such a manner as to move together with the driving source. The lead wire is thus made to swing in conjunction with the movement of the driving source so as to supply power to the moving driving source. A guide shaft is provided along the direction of movement of the driving source, and a helical portion formed in the lead wire is extended or shrunk along the guide shaft so as to supply power to the moving driving source.

Abstract: A self-driving closure device for moving a closure member such as a window glass of a vehicle between an open position and a close position. The device has a motor movable together with the closure member. The motor has a pinion that meshes with a rack secured to the vehicle door or a rotary drum on which an intermediate portion of a wire secured to the door is wound, so that a thrusting force for driving the window glass between the open and close positions is generated as a reactional force as the pinion or the drum is rotated. A mechanism is provided between the motor and the window glass so as to absorb any offset between the direction of movement of the glass and the direction of movement of the motor, so as to ensure smooth movement of the window glass.
