ABSTRACT:
A miniblind Venetian blind. The individual blinds are supported by a string ladder support system on each side. Each string ladder support system has a front vertical ladder string and a back vertical ladder string with short support strings fastened between them like a ladder which supports the individual slats. A main pull string at each ladder support system extends down through holes in each blind to a bottom rail where it is attached. The main pull string goes through the top housing and down over a roller so that the blind can be raised and lowered. A new privacy drawstring is strung along the main pull strings and is connected to the back ladder string at a selected level. By pulling on the privacy drawstrings the blinds below the point at which these privacy drawstrings are attached to the ladder can be tilted independently of the tilt of the blinds above that point. In one embodiment the ends of the privacy drawstring are attached such that by pulling on the privacy drawstring the main drawstring is also pulled.
