Self-aligning canopy structure for connection to a mounting plate adapter utilized for attaching an exit sign to a junction box
First Claim
1. A mounting arrangement for the self-aligning fastening of an illumination canopy for an electrical fixture having a housing and a planar back cover for said housing to an electrical junction box which is located in a wall, said back cover having a centrally located aperture, and latching means arranged about the perimeter of said aperture;
- said self-aligning canopy mounting arrangement comprising;
(a) a plate member positionable over said aperture, latching elements on said plate member for engaging said latching means so as to fasten said plate member to the back cover, said plate member including a center opening for the passage therethrough of electrical wiring extending from the electrical junction box;
means on said plate member for mounting a canopy thereon in predetermined relationship with a junction box; and
a plurality of holes extending through said plate member at predetermined locations to facilitate insertion therethrough of fasteners for mounting said plate member to said electrical junction box whereby the back cover is positioned in closely spaced relationship with said electrical junction box; and
(b) an illumination canopy including structure engage able with said canopy mounting means on said plate member for positioning said canopy on said plate member in alignment with canopy attaching structure in a junction box, said canopy mounting means on said plate member comprising a plurality of spaced slots located about the center opening in said plate member;

Abstract
A structure for aligning a canopy for an exit sign with a standard wall-mounted electrical junction box. The structure is constituted of a separate plate which is adapted to be fastened to the back cover of an exit sign so as to form a mounting structure adapted for facilitating the attachment of the exit sign to a wall-mounted electrical junction box, and which incorporates slots adapted to be engaged by protuberances on the canopy for aligning the latter with the junction box in predetermined selective orientations.
