Abstract: A modular plate assembly for hanging articles on a wall, comprising at least one and preferably a number of releasably interconnected plates, to be screwed on a wall, and at least one hook bracket, to be secured to the plates while concurrently hiding the head of the screw. The plates are endwisely interconnected in pairs by a tenon and mortise joint, including short hollow studs from one end section of one plate to frictionally engage large bores in one section of another plate. The screws engage through the hollow of the studs, to be driven into the wall. The hook bracket has a cavity provided with a railing, and each end of the plates has a tab whereby two proximate tabs from two adjacent plates are designed to be frictionally releasable engaged through the cavity of the hook bracket, to retain same in position for supporting the load of said article.

Abstract: A structure for facilitating the gripping and operating of a control lever of an electrical switch plate mounted into an electrical box embedded into a wall. The structure comprises a movable plate having a large central projection. The projection defines a trough in which the control lever engages, and two large abutting surfaces opposite the trough and orthogonal to the wall, the plate being slidable within a plane parallel to the wall. A cover is fixedly secured to the electrical box by its square central section the plane of which is interiorly offset with respect to the main body of the cover. The central section is upwardly and downwardly open to enable sliding action of the movable plate parallel to the wall, within the plane of the cavity. Thus, the movable plate hides the control lever as well as the screws that secure the cover to the electrical box, and is retained by the guide walls of the cover.
