ABSTRACT:
A cord lock and release system for use in a window blind assembly. The system has a stationary member and a movable member. The movable member is positioned so that at least one lift cord can move across a portion of the movable member when the movable member is in an open position. The lift cords will be restrained by frictional contact with the movable and stationary members when the movable member is in a locked position. The movable member is biased towards a locked position. A release linkage is attached to the movable member so that when a force is applied to the linkage the movable member is moved toward the open position.
