  • Patent number: 4811466
    Abstract: A realeasable pull cord engagement device for venetian blinds having a mounting post consisting of a cylindrical pedestal extending from a base and a stud extending from the center of the outer end of the pedestal. A slider has end and side walls encompassing a cylindrical hollow portion which slides over the pedestal. Aligned openings pass through opposite portions of the side walls of the slide and through the pedestal. A conical spring abuts the inside the end wall of the slider and engages the stud to urge the slider and pedestal apart so that a pull cord passing through the openings is engaged due to misalignment of the openings. When the slider is pressed over the pedestal the openings are aligned and the pull cord may readily be pulled through them.
