ABSTRACT:
A set of window covering panels may be raised or lowered from a header mounted upon the window casing. Pull cords and drop cords on the panels permit the panels to be raised and lowered one at a time or all at a time. Guide members keep the panels in vertical alignment and cam surfaces permit one panel to slide up behind the next higher panel when shifting the panels into a nested condition.
