Patent

CA 2134664

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.

La présente invention porte sur un dispositif enrouleur de câble à deux tambours pour câble à conducteur méplat qui a des moitiés de caisse supérieure et inférieure (11, 12) de forme générale semi-cylindrique qui s'assemblent à pression au-dessus d'un arbre mixte (16) de manière à former deux compartiments. Le premier compartiment (13) est un compartiment d'enroulement divisé en deux par une nervure à fentes (20) sur l'arbre dans ce compartiment. Le câble à conducteur méplat est reçu dans les deux côtés du compartiment par des ouvertures (19, 19') dans les parois du compartiment. Dans le deuxième compartiment (14) se trouve un ressort hélicoïdal plat (23) fixé sur son bout extérieur à une cuvette de ressort (24) de forme générale cylindrique à l'intérieur du compartiment, et fixé sur son bout intérieur à l'arbre mixte dans ce compartiment. La cuvette de ressort est empêchée de tourner, sauf pour serrer le ressort, de sorte que l'arbre est continuellement sous tension pour enrouler et dérouler le câble dans le compartiment d'enroulement.
