Abstract
A cord lock for a venetian blind or shade, such as a pleated shade, having a housing with a stationary pulley and a serrated cam or rivet guided in parallel, aligned S-shaped slots, the cam locking the raised lift cord of the blind or shade against the pulley. The S-shape of the slot maximizes the angle of approach of the slot with respect to the cord and pulley to thereby increase the sensitivity of the lock.
