ABSTRACT:
A segmented shutter or gate with a plurality of gate segments which have dowels on both sides in the area of the upper edge and in the area of the lower edge of the gate segment. The upper dowels are connected in an articulated manner with transporting chains guided along vertical guide rails and driven by chain wheels which transfer the ends of the upper dowels onto storage rails. The lower dowels ride over control cams horizontally moving the lower portion of the gate segment toward the storage rails to allow the next lowermost gate segment to proceed upwardly with the transporting chain.
