ABSTRACT:
An improved venetian type blind has slats each slat having at least two slots along one edge of the slats and one slot on the opposite edge of the slats. A slot on one edge is not opposite a slot on the other edge. Ladders having opposite cord type rails and rungs extending therebetween, are positioned so that one rail of a ladder is outside each of the slots and connected to the bottomrail. A lift cord passes through each of the slots between the slat and the ladder rail. A tilt mechanism attached to the headrail moves the rails of the ladders together when the blind is changed from an open to closed position.
