Cover plate assembly
First Claim
1. A cover plate assembly for a wall box mounted in an opening in a wall, the wall box having at least one pair of tabs provided with threaded holes on standard centers adapted to receive screws mounting at least one electrical circuit device within the wall box, the assembly comprising:
- a frame for overlying the wall surrounding the opening in which the wall box is mounted, the frame having an inside perimeter dimensioned for surrounding the wall box, and inwardly projecting flanges having openings for overlying the threaded electrical device mounting holes for engagement by the electrical circuit device mounting screws,a safety plate for overlying and fixing to each electrical circuit device, each safety plate having an outer edge dimensioned vertically to overlie the frame inwardly projecting flanges and dimensioned horizontally for covering the space occupied by the electrical circuit device to which each safety plate is fixed, and horizontal projections on two diagonally opposite corners adapted to engage a corner of the inside perimeter of the frame,a decorative cover plate having an outer edge dimensioned to be received immediately inside the frame and having at least one opening for accommodating any outwardly projecting portion of each electrical circuit device mounted within the wall box, andmagnetic means for magnetically holding the decorative cover plate to the frame so the assembly appears to be free from any attachment means.

Abstract
A cover plate assembly for a wall box mounted in an opening in a wall, the wall box having at least one pair of tabs provided with threaded holes on standard centers adapted to receive screws mounting at least one electrical circuit device within the wall box. The assembly includes a frame situated to overlie the wall surrounding the opening in which the wall box is mounted, the frame having an inside perimeter dimensioned to surround the wall box, and inwardly projecting flanges having openings to overlie the threaded electrical device mounting holes for engagement by the electrical circuit device mounting screws. The assembly also includes a safety plate overlying and fixed to each electrical circuit device, each safety plate having an outer edge dimensioned vertically to overlie the frame inwardly projecting flanges and dimensioned horizontally to cover the space occupied by the electrical circuit device to which each safety place is fixed. A decorative cover plate has an outer edge dimensioned to be received immediately inside the frame and has at least one opening accommodating any outwardly projecting portion of each electrical circuit device mounted within the wall box, and composite magnetic strips hold the decorative cover plate to the frame so the assembly appears to be free from any attachment means.
