The venetian blind lift cords extend into a lengthwise cord passage inside the wand and the lift cord operating mechanism includes a lift member mounted for movement along an outer side of the wand and lift cord, an engaging member in the cord passage for moving the lift cords to raise and lower the blind in response to movement of the lift member along the wand. The operating means includes lock means for locking the lift cord engaging member at selected positions along the wand.
Claims25
A window blind comprising, a headrail, a bottom rail, flexible ladder means between the bottom rail and headrail and supporting a plurality of slats, lift cord means having one end connected to the bottom rail and extending from the bottom rail into the headrail, control means for tilting the slats and for raising and lowering the bottom rail, said control means including an elongated wand having lengthwise extending wand passage means opening along one side of the wand and wand connector means for mounting the upper end of the wand on the headrail for turning relative thereto, slat tilt operating means connected to the ladder means and responsive to turning of the wand for tilting the slats, the wand connector means providing cord passage means between the headrail and an upper end of the wand passage means, the lift cord means extending from the headrail through the cord passage means in the wand connector means and downwardly into the wand passage means, manually operable lift cord operating means including a lift member mounted for movement along an outer side of the wand and lift cord engaging means inside the wand passage for moving the lift cord means to raise and lower the bottom rail in response to movement of the lift member along the wand, the lift cord operating means including lock means for locking the lift cord engaging means at selected positions along the wand.
A window blind comprising, a headrail, a bottom rail, expansible and collapsible shade means between the bottom rail and headrail, lift cord means having one end connected to the bottom rail and extending from the bottom rail into the head rail, control means for raising and lowering the bottom rail, said control means including an elongated wand having lengthwise extending wand passage means opening along one side of the wand and wand connector means for swingably connecting the upper end of the wand on the headrail, the wand connector means providing cord passage means between the headrail and an upper end of the wand passage means, the lift cord means extending from the headrail through the cord passage means in the wand connector means and downwardly into the wand passage means, manually operable lift cord operating means including a lift member mounted for movement along an outer side of the wand and lift cord return guide means inside the wand passage for moving the lift cord means to raise and lower the bottom rail in response to movement of the lift member along the wand, the lift cord means extending downwardly in the wand passage and around the cord return guide means and then upwardly in the wand passage, and means for anchoring a second end of the lift cord means against movement in a direction lengthwise of the wand whereby movement of the lift cord actuating means along the wand produces an amplified travel of the bottom rail, the lift cord operating means including lock means for locking the lift cord engaging means at selected positions along the wand.
