Abstract

Extensible-articulated chain for shutters, which is essentially characterized by being constituted by a series of elongated laminar pieces concatenated together, by a second series of pieces similar to rings, so that each of the elongated pieces has, in its area central, an angular fold across its width, which constitutes a transversal support intended to come into contact and make a stop with an internal partition wall of its corresponding blade, being in the upper half of the piece an opening, elongated in a direction perpendicular to the the major axis of the aforementioned part, while the lower half of the repeated part has an opening of larger dimensions, which extends substantially to the aforementioned transverse stop and stop and the annular intermediate connecting pieces closed, with their closing ends a bevel, are linked with the upper opening of one of the elongated pieces in articulated form, and in turn linked with the part and bottom of the adjacent sheet piece, through the lower opening, constituting an extensible sliding joint, with the additional feature that each elongated piece is practically contained, all the less its upper protruding end, in a hollow blade, and the pieces as a ring, they are susceptible, when the shutter closes, to enter the slat corresponding to the elongated piece that is on top of it.
