Abstract
New elevator cab construction and reconstruction of old elevator cabs are frequently presented with the problem of increasing the interior size of the elevator cab in an elevator shaft of limited size. This invention relates to an elevator cab design providing a novel way of increasing internal cab size of a standard elevator cab while still retaining decorative design features by having removable decorative panels. The elevator cab is constructed of the normal elements, namely, a platform, a ceiling, cab shell walls, stiffeners and corner stiffener risers. The cab shell walls have a base and transom and shell panels there between designed to overlap one another so as to be readily attached by spot welding or adhesive. The stiffeners are hat-shaped elongated sections typically of stainless steel that are attached to the inside of the shell panels. The stiffeners may also be formed by hat-shaped ribs formed in the shell panels. Removable decorative panels of approximately the same thickness as the stiffeners are hung directly on the interior of shell panels between the stiffeners. Advantageously, the use of the stiffeners on the inside of the shell panels and the mounting of the decorative panels on the shell panel between the stiffeners increases the internal width and depth of the elevator cab.
