Abstract: Arrangement of slat screens for solar protection of the type having a number of slats (24;44) supported by girders (5) or the like, which slats are placed apart from each other and together form a solar screen. The girders (5) have slat holders (16) with projections (21) with surfaces which face away from each other. These surfaces slope in such a way relative to each other that they form together an entry portion (22) which on the inside is terminated by a groove (23) in each projection. The slats (24) are provided with a fixture (28,29) which has two opposing flanges (28) with outer hook-shaped projections (29) facing each other. The distance between the flanges is so chosen that the hook-shaped projections can be guided onto the widened out entry portion (22) so that during the bending of the flanges they are made to pass the widest part of the entry portion which is wider than the distance between the hook-shaped projections.

Abstract: The upper edge of an awning slat that is suspended obliquely in position is bifurcated into a channel-like structure running along the edge, having inwardly projecting beads on the free edges of the channel. For suspension of the slat, at various places along its length, the beaded channel is forced to spread and snap into notches behind twin barbs of a bracket. Each bracket has parallel ridges bending out from a base to meet the bifurcated grasping webs of the awning slat, the ridges of the bracket being barbed, so as to provide an oblique surface to spread the connecting webs of the awning edge apart until their beads snap into grooves between the barbs and the bracket base. The awning slat with its bifurcated edge is integrally made by extrusion of aluminum alloy and the brackets are relatively short pieces of aluminum alloy extrusions.
