conventional venetian blind nonetheless the rolled version has been selected out by the inventors for discussion because it is the only instance in which they were able to discover the tilting of a slat array in combination with a honeycomb or pleated fabric shade fig3 illustrates in sectional isometric detail the preferred embodiment employing what is termed a pleated blind 30 with articulative cambered dogleg slats 32 here the cambered slat is constructed by inserting a stiffener 34 of dogleg shape between portions of the pleating material 36 so that it is effectively hinged that is articulative along the slat front lateral edges 38 that are coincident and coextensive with the pleat 30 troughs 40 the rear lateral edges 42 of the slats 32 are free and are cambered curved uniformly in one direction the direction of curvature is generally upward or towards the means not shown of articulation when the invention is oriented so that its slat array is horizontal or vertical respectively articulator cord 44 is used to gang the articulative slats 32 so that they may be moved or deflected uniformly in one direction the articulator cord is joined to each slat 32 by a semi rung 46 which digresses from the cord and attaches to the underside or convex surface of cambered slat 32 at anchor 48 location those of ordinary skill will recognize that function of rung 46 to the underside or convex side of the slat 32 may be achieved by various means as will.
