Elevator cab

Abstract

An elevator cab, and methods of constructing same, in which sections of a drop ceiling with integral lighting are factory assembled. The sections of the drop ceiling are brought to a job site and assembled in the elevator cab after the cab enclosure, which includes side walls and a canopy, has been assembled on a platform in a hatchway. First and second side sections or assemblies are suspended from the canopy via quickly coupled sections of hanger strap assemblies, and an intermediate or center section, which may include more than one assembly, is then positioned and supported by the first and second side assemblies. The assemblies which make up the center section of the drop ceiling are leveled via thumb screws accessible through an emergency opening in the canopy, and the assemblies of the center section are fixed to the side assemblies, also via thumb screws accessible through the canopy opening. One assembly of the drop ceiling is directly electrified from an external source, and plugs and receptacles on the assemblies, accessible via the canopy opening, are interconnected to complete the electrification of the drop ceiling. The drop ceiling may include incandescent down lights mounted in elongated metallic members which also function as electrical junction boxes and stiffening ribs, and/or fluorescent perimeter lighting, as desired.
