Abstract

Improved arrangement in louvers of adjustable louvers, characterized in that the louvers, independent of each other and adjustable, are linked at both ends to respective support pieces that are independent and sliding on their corresponding lateral guides fixed to the frames of the shaft; each of said supports is anchored, in turn, to one of the successive central knots of the blades that make up, articulated between each other, two earwire extenders located in two of the opposite frames; said extenders have fixed to the frame one of its end nodes and a threaded spindle, arranged longitudinally in the same frame, is fixed in a nut fixed with one of the intermediate nodes of the extender so that the rotation of said. Spindles, linked by a transmission bar that receives the movement of an accessible command, causes the displacement of the referred nuts and the consequent extension or retraction of both extenders which drag, on their part and through said support pieces, to the lamas unfolding or folding them; all this so that, if the extenders can be mounted in the vertical frames or in the horizontal ones, it is also optional to place the slats in respectively horizontal or vertical position, leaving the slats, during the total opening of the shutter by folding the extenders, collected and attached to each other staying in the cashier prepared for that purpose in the corresponding frame.
