Abstract: A slatted roofing device, includes a frame (1) receiving a lower series (2) of grid-type mounted slats and at least a support (3) superimposed on the frame (1) receiving an upper series (4) of grid-type mounted slats, the support (3) being transversely mobile with respect to the longitudinal direction of the slats on the frame (1) to modify the lateral position of the slats of the upper series (4) relative to those of the lower series (2), the slats shifting from a completely overlapping position when the roof is open to a partial overlapping position when the roof is closed. The device includes an apparatus for lifting the support (3) relative to the frame (1) to allow air to pass through the roof even when the series of upper (4) and lower slats cover the whole roof surface.

Abstract: An insolation regulation, modulation and distribution device includes a support structure (1) for a cover for the space to be protected from the sun and control elements for moving the cover periodically in the plane thereof. The cover comprises at least one layer (2) which is provided with at least two types of zones (3, 4) having different light transmission properties, the distribution of which is predetermined.
