Abstract: An elevator door panel for closing the opening to an elevator shaft comprising a generally planar steel sheet reinforced on the shaft side by a perimeter framework and intermediate vertical stiffening members. At its lower edge the panel includes a resilient seal member supported on a structural steel construction that is generally symmetrical about a vertical plane at a mid-section of the panel thickness.

Abstract: An elevator cab constructed in-situ from elongated channel shaped pans. The pans have their ends bolted to steel alignment angles and their flanges bolted to abutting flanges of adjacent pans. The pans and alignment angles can be bolted together with bolts and nuts of a common size and preferably are arranged to rotationally interlock with the bolts to simplify tightening of the nuts and enable the cab to be conveniently assembled even in low clearance hoistways. Light fixtures are nested in associated pans forming the cab top and are protected by sheet metal panels secured to the flanges of such pans. An emergency exit door on a top panel has a unique safety switch interlock.
