  • Patent number: 4037865
    Abstract: Device for mounting door handles on a door. A pair of flat annular discs disposed one to each side of the door have central screw fittings to attach to escutcheon plates which carry the door handles. Discs are interconnected by screw clamps which extend through one or more holes in door and draw the discs together against the door. Each disc has three circumferentially spaced tongues which extend generally circumferentially of the disc but project inwardly toward the door. Tongues are spaced radially inwardly from perimeter of the disc. Tongues can serve to locate discs concentrically of an appropriately sized circular hole through the door by engaging the wall of the hole but in the event that tongues cannot enter a hole in the door but engage side faces of the door they can be deformed by engagement with the door under action of clamp means to allow discs to come flat against door faces.
