<p>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 (11, 12) which snap together over a dual-purpose shaft (16) to make two compartments. The first compartment (13) is a cord take-up compartment which is divided in two by a slotted rib (20) on the shaft in that compartment. Flat wire cable is received in both sides of the compartment through apertures (19, 19') in the walls of the compartment. In the second compartment (14) is a flat coil spring (23) fixed on its outside end to a generally cylindrical spring cup (24) within the compartment, and fixed on its inside end to the dual-purpose shaft in that compartment. The spring cup is held against rotation except to tighten the spring, so the shaft is continually under tension to rotate and retrieve the cable into the take-up compartment.</p> |
