Abstract
A modular wall system comprises a plurality of wall modules in end to end relation, each module having a spring loaded ceiling channel engaging the ceiling and a floor channel frictionally or mechanically engaging the floor. The ceiling channel has a shallow upwardly opening longitudinally extending channel-shaped adapter plate on its top adapted to engage a strip secured to the underside of a ceiling tile support hanger for stabilizing and aligning the module. The ceiling and floor channels have sides formed with longitudinal grooves adapted to be engaged by a suitable dolly for contracting or expanding the ceiling channel away from or toward the ceiling to enable each module to be maneuvered into and out of position in the line of the wall. A wall comprising a plurality of such modules is erected with the aid of the dolly by moving each module one at a time in a tilted position to the proposed wall line or plane with the spring-loaded ceiling channel contracted toward the top of the module, pivoting the module about an axis adjacent to the floor into the vertical plane of the wall with the bottom edge of the wall resting on the floor, and releasing the ceiling channel under press…
