ABSTRACT:
A louvre type roof structure includes a plurality of parallel slats mounted on carrier elements which in turn are mounted on carrier beams such as to permit pivotal displacement of the carrier elements and the slats between a closed position in which the slats are disposed in a roughly coplanar orientation, and an open position in which the slats are disposed in spaced apart generally parallel planes. The carrier elements are secured to the slats by engaging the slats without penetrating the slats, so that each slat is located in a fixed planar orientation relative to the respective carrier. Mounting of the carrier elements to the carrier beams is by means of a pair of mounting levers for each carrier element. One of the pair of mounting levers is a fixed lever securable to a carrier beam in a selected position, and the other lever is a free lever displaceable relative to a carrier beam. Each fixed lever is rotatably attached to its carrier element, and each free lever is fixedly attached to its carrier element to permit pivotal displacement of such carrier element relative to the fixed lever and carrier beam when the free lever is displaced relative to the carrier beam. Each fixed lever has releasable attachment formations for releasably attaching the lever to a carrier beam in a selected position. By way of development, each carrier beam may be in the form of an elongate carrier strip and a beam, the carrier strip being fastened on the beam.
