ABSTRACT:
A window blind assembly includes a headrail having a longitudinal axis, a bottom rail suspended below the headrail and a window covering material extending between the headrail and the bottom rail, the window covering material having an upper end attached to the headrail and a lower end attached to the bottom rail. The assembly also includes a traversable tube disposed in the headrail, the traversable tube having first and second ends. The assembly includes a threaded support rod secured to the headrail adjacent a first end of the tube, the threaded support rod being threadably coupled with the first end of the tube for providing traversing motion to the tube. The assembly also includes a spring motor secured to said headrail adjacent a second end of the tube. The spring motor has drive gears in communication with the second end of the traversable tube for selectively rotating the tube, whereby the drive gears rotate about respective axes that are substantially parallel to the longitudinal axis of the headrail.
