Abstract:
1. A horizontally slatted blind comprising: a header for mounting said blind across an opening; a rod extending longitudinally within said header and mounted thereto, said rod having a first end and a second end and a longitudinal axis, said rod being rotatable about said longitudinal axis; a plurality of slats, each said slat having a first end and a second end defining first and second side edges, a front corner at each of said first and second ends and a rear corner at each of said first and second ends, said slats being disposed horizontally and spaced vertically below said header; a plurality of stiffeners, one stiffener being for each of said plurality of slats, each said stiffener having opposing transverse side edges, each said stiffener longitudinally extending substantially from said rear corner at said first end to said rear corner at said second end of its respective slat, each stiffener preventing slat weight from bending said slat between opposing longitudinal ends of said stiffener; a first tilt cord and a second tilt cord attached to and extending from each of said first and second ends of said rod; said slat ends each including a clip, each clip having a front and rear end defining a clip length, each clip front and rear end respectively positioning said first and second tilt cords adjacent to said first and second ends of said slats, said tilt cords not passing through holes in said slats, wherein: said header having a depth defined by opposing front and rear header surfaces, said header depth being greater than said clip length and being substantially less than said length of said slat side edges; and said blind including means for attaching said first and second tilt cords to said first and second ends of said rod whereby, when said rod is rotated about said longitudinal axis, one of said first and second tilt cords is lowered while the other of said first and second tilt cords is raised by an equal amount, so that said plurality of slats open or close in unison.
