Abstract: A venetian type blind has a bottomrail, a headrail positioned above the bottomrail and a set of slats. Upper slats or no slats are carried on a set of upper ladders extending from the headrail and a set of lower ladders extending from the bottomrail. Each upper ladder is connected to a lower ladder by a connection device that connects an upper ladder rail to a lower ladder rail. Alternatively, all of the ladders can be connected to a single rail located between the headrail and the bottomrail. The upper ladders are connected to a tilt mechanism. At least two lift cords are attached to the bottomrail, running past slats through the headrail. At least two tilt cords are provided. Each tilt cord runs through the headrail, passing adjacent to one rail of an upper ladder and is connected to either one connector or a rail of the ladder adjacent to a connector.

Abstract: A bottom stacking and top stacking venetian type blind has a fixed headrail containing a tilt mechanism which tilts the lift cords as well as the movingrail and bottomrail, maintains the centerline plane and center of gravity in the same place throughout the operation of the blind, and provides cord locks for the two sets of lift cords. This blind consists of the fixed headrail containing both tilting and lifting mechanisms; a one-piece or two-piece movingrail; a one-piece or two-piece bottomrail; and a plurality of slats which rest on ladders between the bottomrail and movingrail. The ladders are typically made of cord, but the hardware of this blind will also accommodate fabric tape or sheet ladders. There will always be at least one pair of lift cords which control the movingrail; one cord in the front, and one in the rear. The bottomrail will also have two lift cords passing through, one on each side, if it is a single rail; or four cords for a double rail.
