ABSTRACT:
A suspension cord guide for a window blind includes an L-shaped guide member positioned within the head rail of the blind. The guide member is positioned adjacent an opening in the head rail through which the suspension cord extends. Also, the suspension cord guide includes a hollow spindle surroundingly engaged with a tilt rod in the head rail, and the spindle is formed with an abutment surface on its end nearest the opening. A finger of the L-shaped member extends toward the spindle, with the suspension cord being fed onto the spindle next to the abutment surface by the guide member. In addition to guiding the cord onto the spindle, the finger of the L-shaped guide member contacts the coil of the suspension cord that is established on the spindle nearest the finger. When the tilt rod (and, hence, spindle) is rotated, the cooperation of structure between the finger and the suspension cord coils that are established on the spindle causes successive coils to be pushed along the spindle and away from the opening in the head rail, thereby ensuring that the coils do not overlap each other.
