A cord lock for window coverings has one or more cams adjacent a locking surface over which a one or more lift cords travel. The cams may be spring biased to a locked position in which they press the lift cords against the surface. A release member through which the lift cords pass is provided. Transverse movement of any cord passing through an opening in the release member moves the release member from a first position, in which the cam or cams are in the locked position, to a second position at which a cam engaging portion of the release member engages the cam and the cam is in the unlocked position. Movement of the release member from the first position to the second position maintains the cam in the unlocked position. |
