Abstract
Abstract A plurality of motors are affixed to opposite spaced parallel walls of a room. A plurality of cable-type support members each has a first end affixed to a false ceiling at a corresponding point thereof and a second end affixed to a corresponding one of the motors. The false ceiling is thus supported in parallel spaced relation with the ceiling of the room and is selectively varied in its distance from the ceiling of the room by operation of the motors.
