Abstract:
A horizontal window blind apparatus having at least a first and a second slat disposed parallel and spaced relative to each other, said apparatus comprising:a first tab secured to the first slat, said first tab defining a first opening and a second opening disposed between said first opening and the first slat; a second tab secured to the second slat, said second tab being aligned relative to said first tab, said second tab defining a third opening and a fourth opening disposed between said third opening and the second slat; a first elongate control extending through said first and said third openings; a first locking device for selectively locking said first control relative to said first tab; a second locking device for selectively locking said first control relative to said second tab; a second elongate control extending through said second and said fourth openings; a third locking device for selectively locking said second control relative to said first tab; and a fourth locking device for selectively locking said second control relative to said second tab, the arrangement being such that relative movement between said first and second control tilts the slats relative to each other so that the slats move between a first disposition thereof in which the slats are open and a second disposition thereof in which the slats are closed.
