Abstract
In a vertical blind with a blind head, a tilt rod for tilting vanes suspended from the blind head in carriers, and a traverse cord for reciprocating the carriers in the head to thereby open and close the blind: a lever connected to the tilt rod for rotation therewith and having an opening spaced from the tilt rod and through which the traverse cord passes. Rotation of the tilt rod will bend and squeeze the traverse cord and thereby prevent its reciprocation when the vanes of the blind are tilted closed.
