Abstract

Articulation for slats of blinds, characterized by the fact that the bonding between consecutive tubular slats, is established by means of coupling pieces that are linked correlatively to each other, staying at the rate of one piece in each slat for each succession of such pieces, to which effect in said slats have been made grooves in their upper and lower bases, according to the longitudinal sense thereof, which coupling parts are flat sheet type, with a central extension on its upper part, provided with projections laterally at its free ends, and with a lower fold, each of whose faces of this fold extract fins forming an angular opening downwards, so that in any case the elbow of said fold is applied in the groove of the lower base of the lama, while the respective fins rest on the same base on both sides of the said groove, while on the upper edge of the foot the upper base of the slat is supported by protruding through the groove of this base the extension of the blind, the coupling parts insert and support the lateral protrusions of its upper extension within the elbow of the upper immediate part, while that in the retracted position of said shutter, with direct support between its slats, the said extensions penetrate into the immediate superior piece, without interlocking between them.
