ABSTRACT:
An improved venetian type blind has slats having at least one small hole adjacent one edge of each slat. At least two ladders having opposing cord type rails and rungs extending therebetween carry slats and are connected to the bottomrail. A first lift cord runs through the holes and adjacent to the first ladder. A second lift cord runs across the opposite edge of each slat adjacent the rail of a second ladder. A similar arrangement can be provided using pairs of spaced apart holes and two pairs of lift cords. A tilt mechanism attached to the headrail moves the oppositely disposed lift cords and the rails of the ladders together when the blind is changed from an open to closed position.
