Abstract
In a ceiling assembly, a parallel array of horizontally elongated panels each having vertical major surfaces and a horizontal top flange and a plurality of spaced parallel horizontally elongated stringers extending above and transversely of the panels for supporting the panels, the stringers having horizontal flanges formed with slots in which the top edge portions of the panels are received. The slots are shaped to provide, in the stringer flanges, pairs of facing spring tabs to facilitate insertion of the top portions of the panels in the slots and to interlock with the panel top flanges.
