Abstract
Improvements in the construction of roller shutters, characterized by the fact that the shutters are composed by a plurality of tubular slats, obtained by folding metal sheet, such that in its upper part they present a flat area, with an attachment of the two faces, finished by a curved flange as coupling means in the immediate upper slat, while its lower part offers a mouth flanked by two curved recesses, having a transverse partition that delimits upper and lower spaces of the slat, the last of which it constitutes the housing for the coupling flange of the lower immediate slat, with the faculty of deferring it for the closing and opening positions of the shutter, so that the slats in question are provided with end stops for soundproofing the shutter and for the protection of the same against abrasion due to friction in the guide channels.
