Installation for covering a surface using orientatable blades that are translated flat

Abstract

The invention relates to an installation including:a series of orientable slats (3);a slat orientation system (3) adapted to ensure the pivoting of the slats in order to occupy a closed position or an open position;a system for moving in translation the slats (3) between a stowed position and a deployed position;and a control device piloting the displacement system and the orientation system, on the one hand to define from the stowed position of the slats a transition area (Ev) in which each of the slats exiting its stowed position switches from its open upright position to its closed position and conversely for each of the slats arriving to its stowed position, and on the other hand to ensure the translational displacement of the slats in the closed position outside the transition area (Ev).
