<p>A venetian blind in which there are at least two sets of slat supports each in the form of ladders, each set of ladder supports comprising two or more ladders these ladders each having longitudinally spaced cross-rungs (20,26) at the same location with one group of venetian blind slats (28,30) being mounted on the cross-rungs (20,26) of one of the ladders of each set and other slats (28,30) being mounted on the other cross-rungs (20,26). In use, in an open position of the blind, the two or more slats (28,30) at the same location are superimposed on one another. The two or more ladders of each set are independently controllable to provide different visual effects in the closed position of the blind. In another construction used for a skylight, individual slats are mounted between depending double cross-rungs of the slat support ladders. <IMAGE></p> |
