ABSTRACT:
An architectural shutter curtain device having a train of a plurality of slats connected in series and adapted to be wound to form a plurality of turns on a take-up shaft of a polygonal shape having n apices. The width of the slats is varied in accordance with the change in the diameter of the wound shutter curtain device. In a group of n pieces of slats which form any one of the turns of the polygon formed when the shutter curtain device S is wound, the first to (n-2)-th slats and the n-th slat P.sub.n as counted from the winding start end have an equal width corresponding to the length of one side of the polygonal form, while the (n-1)-th slat of the group has the same width as the first to (n-2)-th slats of the group of n pieces of slats which form the next turn of a polygonal form of an increased size. The take-up shaft for winding the shutter curtain device thereon is so constructed that the hinges on the leading ends of the first to (n-2)-th slats of the successive turns are superposed on radial lines interconnecting the center of the polygonal form and the first to (n-1) apices of the polygonal form, while the hinges between the (n-1)-th slat and the n-th slates of the successive turns are superposed along a line which extends in parallel with a radial line passing through the center of the polygonal form and the n-th apex of the same.
