ABSTRACT:
A vertical blind system to selectively block and expose an area from a front vantage point. The vertical blind system includes first and second slats, each having a body with a top and bottom and a width between spaced substantially straight edges which extend between the top and bottom of each slat. A support/guide system maintains the first and second slats in an operative state and allows the first and second slats to be selectively repositioned between a) a first/open position wherein a space is defined between the first and second slats as viewed from the front vantage point and b) a second/closed position wherein the straight edge on the first slat horizontally overlaps the second slat a first predetermined amount as viewed from the front vantage point. There is a horizontal projection from one of the edges of one of the first and second slats so that the one of the edges and the projection cooperatively overlap the other of the first and second slats an amount greater than the first predetermined amount as viewed from the front vantage point with the first and second slats in the second/closed position.
