Cord lock mechanism for venetian blind

摘要

A cord locking mechanism is described for a venetian blind for locking the flexible blind lifting and lowering member in any selected position by gripping the member between a guide and a serrated locking pin movable toward and from the guide; a helper member is movable toward and from the locking pin when in its unlocked position in order to insure engagement of the flexible member with the locking pin and movement of the locking pin into a locking position.
