Abstract: A device for hanging an object on a supporting structure such as a wall comprises a one-piece backing plate having a plurality of co-planar bars extending between co-planar side rails and forming slots between the bars, with the backing plate including offset shoulders for offsetting the planes of the side rails and the bars to provide a space between the bars and the wall when the backing plate is affixed to the wall. A one-piece hook for supporting the object includes a planar body portion and a protrusion forming with said body portion a U-shaped receptacle for accepting an object to be mounted to the wall.

Abstract: An adjustable device for hanging a wire-supported object on a wall device comprises a first bar for attachment at to the wall in a horizontal position, a second bar perpendicular to the first bar and having a hook or hooks for accepting a wire secured to the object to be hung, and a connector with channels that hold the bars for sliding movement relative to each other. The first bar is secured to the wall at its ends and then the connector can be moved horizontally along the first bar and the second bar can be moved vertically within the connector. This permits the object to be positioned at precisely the desired position even after the hanger device is secured to the wall, unlike conventional devices that must be removed from the wall for repositioning. A spring-loaded pin on the connector is accepted into openings in the bars to lock them into the position that places the object on the desired position.
