  • Hanger for suspended ceiling
    Patent number: 4979715
    Abstract: A hanger for holding a suspended ceiling made of a continuous wire. The wire is shaped at one end, to form two superposed loops adapted to surround a screw which is intended to be threaded in a supporting ceiling. The wire is bent near the loops at about 90 degrees relative to the plane of the superposed loops. The short end of the wire is either twisted to the body of the wire or located inside the apex of the angle formed by the loops and the body of the wire so that it will be tightened when the screw is threaded in the supporting ceiling and the body of the wire is under tension.
