Title:
DEVICE FOR WINDING SUSPENSION CORD OF BLIND
Document Type and Number:
Japanese Patent JP3249617
Kind Code:
B2
Abstract:
PURPOSE: To evenly wind a cord without overlapping of the cord on a winding drum.
CONSTITUTION: One end of a cord is fixed to a winding drum 1. The drum is provided with a smooth part 8 having a larger diameter than the initial diameter of the drum 1, disposed at a distance separated from a fixed position 12 of the cord and limited by a shoulder 9. The cord 11 to be wound is guided approximately tangentially to the shoulder. The turns 11a formed on the large diameter part is pushed back by the shoulder 9 under the effect of the load. The large diameter part 8 has such a length that the tension of the cord gets to zero at the turns 11b distant from the large diameter part. These loose turn parts are positioned beside each other on the portion 1 of the drum ensuring an even winding without overlapping of the cord.
