ABSTRACT:
The shutter includes a curtain formed of elongated bars hinged to one another at longitudinal edges and guided at their ends in laterally spaced guide grooves extending along opposite sides of an opening to be controlled by the shutter. A rotatable member is mounted in an upper receiving zone, such as a lintel above the opening, and the rolling bar curtain is trained about this member for direction reversal during raising and lowering. The laterally spaced guide grooves extend along the peripheral portion of this rotary member and are then branched to form branch guide grooves extending downwardly from the rotatable element into a recess formed in the lintel or the like. Guide elements, such as pins or rollers on the ends of each bar, cooperate with the branch guide means to conjointly guide the bars to form at least one vertical pile of bars superposed in horizontal orientation in the recess, responsive to raising of the curtain. The rotatable element may be circular or may be polygonal and, if polygonal, has sides each conforming to the width of a bar of the curtain.
