PCT No. PCT/FR97/00643 Sec. 371 Date Mar. 23, 1999 Sec. 102(e) Date Mar. 23, 1999 PCT Filed Apr. 11, 1997 PCT Pub. No. WO97/38202 PCT Pub. Date Oct. 16, 1997An opening and closing device for use with a shutter system for protecting a building space, such as a slat-type roller blind for a window, includes a series of slats capable of sliding in two generally vertical, laterally positioned guides (4). The slats are hooked to each other by hooking systems (7), and include a male/female interlocking system along their length. The device can be used to lower or raise the shutter system to close or open the protected space, moving between a totally closed position and a partially or fully opened position. In the closed position, the lower slat rests against a horizontal surface and the slats are interlocked with one another along their length to form a continuous sheet. In the partially or fully opened position, the slats are disengaged and separated from each other by a space determined by the height of the hooking system (7). Mirrored elements (20) can be attached to the faces of at least some of the slats to give bottom floors of the protected space maximum natural illumination while the space remains completely private, and to illuminate upper floors by altering the openings of the slats so that incoming light can be inhibited and/or diffused. This permits regulation of the internal temperature of the building responsive to the openings of the slats. When the slats are completely closed, the internal surface of the shutter system forms a mirror capable of saving a considerable amount of energy. |
