<p>A window blind apparatus that serves to block light while allowing air to pass therethrough. The window blind apparatus includes a number of elongated slats disposed horizontally and that are arranged in a stacked orientation on top of one another. The slats are spaced at fixed intervals and are connected by support cables that extend through apertures on each of the slats. The slats have a zig-zag cross section and preferably include an M-shaped cross section. In this way, the slats are adapted to block light from entering a room, while allowing air to pass through the space between the slats. The blinds include a pull cable disposed on a roller for raising and lowering the blinds as desired by the user.</p> |
