ABSTRACT:
An apparatus for reciprocably moving a desired object is disclosed as adapted for use as a vehicle door window regulator. Included is a drive ball assembly comprising a series of balls of a rigid plastic or like material threaded on a wire or like flexible, nonextensible member. One end of the drive ball assembly is anchored to a window panel. An elongate ball guide on a door frame guides the drive ball assembly along a vertical path. At the lower end of the vertical path is a drive wheel rotatably supported on the door frame and having a series of concavities defined peripherally therein for driving engagement with the balls of the drive ball assembly, the latter being preferably turned approximately right angularly around the drive wheel. By imparting bidirectional rotation to the drive wheel, either manually or by a reversible electric motor, the window panel can be moved up and down via the drive ball assembly.
