Abstract: A pivoting shutter having adjustable slats for buildings includes an upper panel provided with a first group of adjustable slats, mounted by the upper end thereof on a horizontal pivoting shaft. A lower panel is provided with a second group of adjustable slats, hinged by the upper end thereof to the upper panel and connected by the lower end thereof to a driving means for vertical movement for pivoting the panels between an open position and a closed position. First and second connectors are provided, which, when rotating the slats, link the adjustable slats of the first and second groups, respectively. A transmission mechanism links the two groups of slats in the closed position of the upper and lower panels, enabling in the closed position the simultaneous rotation of all the slats, and maintaining the groups of slats unlinked from one another in the open position of the panels.
