摘要： A cord locking assembly mounted in the blind head box or the blind hand grip axially movably fitted on the hollow pole suspended from the blind head box.The assembly comprises a movable plug, a fixed plug hole sleeve for fitting engagement with the plug, a lock compression spring to bias the plug to the plug hole sleeve, lift cords passing through the plug hole sleeve, and means for loosening the lock compression spring. The means is the hand grip in the case of the assembly mounted the hand grip. The means is a knob or pull cord fixed to a holder in which the lock compression spring is mounted in the case the assembly mounted in the blind head box.The lift cords are fixedly locked between the plug and the plug hole sleeve when the means is not operated, are gradually movably locked between the plug and the plug hole sleeve when the means is operated at first to loosen the lock compression spring without moving the plug away from the plug hole sleeve, and released from the locking between the plug and the plug hole sleeve when the means is operated at last to move the plug away from the plug hole sleeve.

摘要： According to the present invention, there is provided an apparatus for lifting and tilting slats in a venetian blind, comprising: a head box; a rotating shaft; ladder drums rotating together with the shaft; drum holders for supporting the ladder drums; ladder rings of an open ring shape and fitted around each of the ladder drums; ladder cords being put on, and secured to, each of the ladder rings; lifting drums; lift cords, wound around each of the lifting drums; slats; and elements for stopping the rotation of the shaft. The apparatus is characterized in that the elements for stopping the rotation of the shaft comprises: a stopper holder on a head box; a drum stopper of a ring shape, axially not slidably, but rotatably, attached to the stopper holder; a stop ring of a ring shape, axially slidably, but not rotatably, attached to the stopper holder; and a spring for axially pressing the stop ring against the drum stopper, the drum stopper and the stop ring having teeth formed on the mutually opposite ends of the drum stopper and the stop ring so that the teeth are engageable with each other. The lifting drum and the drum stopper are engaged so that the drum stopper rotates together with the lifting drum. The lift cord is put on the stop ring, and is hung downward.
