ABSTRACT:
The invention is a dual reel cord take-up device for flat wire cable which has a generally semi-cylindrical upper and lower case half which snap together over a dual-purpose shaft to make two compartments. The first compartment is a cord extension and take-up compartment which is divided in two by a slotted disk on the dual-purpose shaft in that compartment. Flat wire cable is wound on the dual-purpose shaft in both compartments, and extends through two apertures in the walls of the compartment. The cable in one aperture is fixed so it does not move in and out of the aperture. The wire cable in the second aperture is free to extend or retract through the aperture. A spring provides the power to retract cable into the take-up device.
