Abstract: A lightweight elevator cab constructed essentially of aluminum, including upstanding side, rear and front wall portions. Perimetrically flanged, rectangularly shaped aluminum wall panel members have their adjacent flanged edges joined together to form a side wall portion, and in most cases the rear wall portion as well. The rear wall may also be constructed essentially of glass panels, if desired. The lower flanges of the aluminum wall panels are attached to a support platform, and the upper flanges support a canopy formed of aluminum honeycomb sandwiched between two flat aluminum sheet members. The cab front includes a stationary aluminum portion which forms a wiring duct, and an aluminum swing return panel punched to receive car fixtures. The car door includes front and back perimetrically flanged aluminum pan members telescoped snugly together with a reinforcing rib of one pan in contact with the opposing pan member.

Abstract: A method of constructing a mitered, unwelded architrave. Two right angle frames or brackets are constructed, each having first and second legs disposed 90.degree. relative to one another. First and second post sections and a head section are formed with elongated recesses, and appropriate ends mitered. The post and head sections are telescoped on to the two brackets and secured thereto, such that the frames support the architrave at each right angle corner, maintaining tight, butted, aligned miter joints without welding.
