ABSTRACT:
The invention is for a cord system for a dual function window blind. A looped cord acting with a master carrier controls the traversing movement of the vertical vanes. The other, smaller diameter cord controls the tilt of the vanes and is not a looped cord but a much thinner cord with a tassel attached at each end. The tilting is performed by pulling the tassels whereas the traverse is performed by pulling the heavier cord. The first, looped cord slides freely through holes in the tassels. The result is the appearance of a single cord with a tassel on each side.
