Abstract: A louver type roof structure includes a plurality of elongated parallel slats mounted on slat hinges pivotally supported on carrier beams transverse to the slats. The slats are pivotable between a closed position in which their longitudinal adjacent edges overlap each other, and an open position in which the slats are spaced apart. The slat hinges are mounted to the slats at their lower surface and allow pivoting of the slats between the closed position and an extreme open position by an angle of at least 90°, preferably 110°. The pivoting axis of the slat hinge is disposed substantially under the longitudinal edge of the slat which is overlapped by the adjacent slat. The roof structure may comprise a border slat adapted to be displaced when urged by an adjacent slat when the latter pivots towards its extreme open position.
