A window covering combining the appearance of a pleated shade and a mini-blind, which in the open position resembles a mini-blind and which in the closed position resembles a pleated shade. The desired effect can be achieved by utilizing various combinations of drums, tilt rods and tilters in a mini-blind assemblage in combination with a ladder system comprising two oppositely moving ladders, namely an A ladder and a B ladder. A means to further diminish light transmission between adjacent slats, when the blind is in the closed position is also disclosed. The use of an optional double rail construction applicable with any permutation of drums and tilt rods is set forth.

A venetian blind having a head portion, at least one tilt rod, at least one drum on each end of the blind within said head portion, said at least one drum having a front cable mount slot and a rear cable mount slot and mounted for rotation by said at least one tilt rod and, a plurality of spaced slats, each of said slats having a front edge and a rear edge said slats being in a horizontal disposition when said slats are in a first or open position, and a cable ladder system mounted to said at least one drum, at least at opposite ends of the width of said blind, said cable ladder system comprising a pair of ladders designated the A ladder and the B ladder, which ladders each have a pair of spaced vertical side cables, one of which is the front cable and the other of which is the rear cable, said front and rear cables being mounted to said at least one drum in said cable mount slots, said side cables being interconnected by spaced parallel rungs, the rungs connected to the side cables of each of the two ladders being spaced the spacing between two slats, one of the ladder\s rungs being offset one slat space whereby the A ladder and the B ladder each support alternate slats between their side cables; means operatively connected to said at least one tilt rod to rotate said at least one drum and move said A ladder and said B ladder, such that the front cable of each of the two ladders moves in opposite directions, upwardly or downwardly, and the rear cable of each of the two ladders moves in opposite directions, upwardly or downwardly, and the front cable and the rear cable of each of the A and B ladders move in opposite directions, whereby when said at least one drum is rotated, all slats will move from the open position to a second or closed position in alternating movement, one upwardly and the next downwardly such that the front edge of any one slat moving in one direction, touches the front edge of the next adjacent slat moving in the opposite direction to effect a V-closure.
