Abstract
A shade control assembly cooperates with one edge of a shade mounted to a rigid bar for urging the shade into an extended use position from a roller. The control includes constant tension coil springs on opposite sides of the cross member for uniformly controlling opposite edges of the shade in its motion. In a preferred embodiment of the invention, the springs are mounted within slotted guide channels and a guide member in each of the channels is slidably coupled to the cross member. In a preferred embodiment, the shade is retracted against the tension of the springs by a drive motor which rotates the roller thereby winding the shade upon itself for storage. In such embodiment to extend the shade, the motor is driven in a reverse direction, allowing the springs to unroll the free end of the shade from the roller, extending it for use.
