ABSTRACT:
A take up reel for window blind cords, comprising a rotatably driven spool having a cord attachment member fixedly engaged thereto and spaced apart from a cord receiving surface of the spool. The member is adapted to alternatively slidingly engage a cord positioned within said device, when the device is in an unretracted position, and fixedly engage said cord when said device is in a retracted position. In a further aspect of the invention, a cord retraction device comprising a rotatably driven spool with an attachment member adapted to engage a cord thereto is provided, with the spool being further provided with a retainer rotatably engaged to an end thereof and adapted to retain the cord on a cord-receiving surface of the spool. The retainer is rotatable between first and second positions, wherein in the first position the attachment member is exposed for user access thereto, and in the second position, the cap cooperates with the spool to retain the cord on the cord receiving surface thereof.
