Abstract: A suspended ceiling, and components therefor, are described in which a carrying structure, for example in the form of carriers arranged in a grid, have depending therefrom a number of suspension units and a slat assembly, which may have decoratively disposed slats thereon, is mounted on each suspension unit. The arrangement is such that the slat assemblies are capable of at least limited rotation between a number of different positions, the slat assemblies being restrained in each position so that each slat assembly may have its orientation relative to its neighboring slat assemblies varied. This arrangement enables one to produce a very different visual effect simply by rotating certain of the slat assemblies relative to their neighbors. The specification discloses a number of different forms of slat assembly.
