Abstract (en)
[origin: US4653567A] In a window shade which automatically winds up by a releasable spring mechanism, mounted in a rotatable shaft, a roll for a cord is secured to the end of the shaft. A free end of the cord is secured to the roll. The amount of the cord to be wound up on the roll corresponds to the entire winding length of the shade material. The cord forms a loop at which a hand grip is suspended.
