ABSTRACT:
A cordless, cellular window shade uses a conventional roller shade bar with a spring pawl arrangement to raise and lower the cellular, window covering fabric by at least two wide, transversely spaced tapes extending from the head rail of the shade through slits in the cellular fabric and secured to the bottom rail of the shade. Each tape has periodically spaced, alignment openings along its length which engage circumferentially spaced, spokes protruding from the roller shade bar to precisely wind the tape about the roller shade bar as the shade is raised or lowered and thus maintain the bottom rail in parallel relationship with the low profile, head rail.
