Abstract
An elevator cab having a drop ceiling suspended from the cab canopy. The drop ceiling includes a skeleton frame and a plurality of metallic pan members carried by the frame. Each pan member includes a sheet metal member having a lower decorative side viewable from inside the cab, and an upper side having reinforcing and stiffening brackets to which one or more down lights are attached and centered over openings in the sheet metal member. The upper side also carries slidable clip members along the edges of the sheet metal member, with the clip members, when actuated from a retracted to an extended position, securing the pan member to the frame by sandwiching a frame element between the lower sheet metal member and the upper clip members. The sheet metal members of the pan members butt tightly together to conceal intermediate angle members of the frame, and the outer edges of the pan members conceal perimetrically arranged angle members of the frame.
