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.
