he invention relates to a profile designed for the construction of a rolling shutter with flat sides. It is 8 mm wide and 30 mm high, and bears special feet and housings both ensuring the impeccable cooperation of successive leaves. The particular cooperation mode has for result -when the roller is completely deployed and resting on the guides thereof- the formation of a compact planar wall having similar sides; said wall offers, except for complete obscurity, the characteristics of a resistant construction able to be also utilized as a safety rolling shutter. On the contrary, the lighting and aeration of the indoor space are sufficient when the rolling shutter is rolled up. The special plug with the elastic tongue in the middle snaps into the corresponding housing formed on the leaf to permit the correct holding, and the easy mounting or dismounting of the rolling shutter. |
