ABSTRACT:
A cord lock for use in a window covering for selectively locking lift cords in a predetermined position includes a housing adapted to be fitted in the head rail of the window covering with the housing having a pivotal locking lever with a cord gripping formation at one end adjacent a locking surface on the housing and a cord guiding passage at the opposite end through which the lift cords can pass. The locking lever is pivoted about a pivot pin that is located between the cord gripping formation and the cord guiding passage so that the cord gripping formation can move toward and away from engagement with the locking surface with pivoting movement of the locking lever about the pivot pin. A fixed guiding surface is also provided around which the lift cords pass for dependable operation of the cord lock.
