Abstract
A horizontal window blind apparatus having at least a first and a second slat disposed parallel and spaced relative to each other is disclosed. The apparatus includes a first tab which is secured to the first slat, the first tab defining a first opening and a second opening disposed between the first opening and the first slat. A second tab is secured to the second slat, the second tab being aligned relative to the first tab. The second tab defines a third opening and a fourth opening disposed between the third opening and the second slat. A first elongate control extends through the first and the third openings and a first locking device is provided for selectively locking the first control relative to the first tab. A second locking device is provided for selectively locking the first control relative to the second tab. A second elongate control extends through the second and the fourth openings. A third locking device selectively locks the second control relative to the first tab. Also, a fourth locking device selectively locks the second control relative to the second tab. The arrangement is such that relative movement between the first and second control tilts the slats relati…
