Mounting apparatus for anti-condensation mirror

Claim 1

In combination, a reflective rectangular mirror plate, electrical resistance heating mEans incorporating an electrically resistive graphitic compound in sheet form overlying the rear surface of said mirror plate, thermal insulating material overlying said heating means, electrical circuit means for connection of said heating means to a source of electrical power to thereby heat said mirror plate and prevent condensation thereon; bracket means including a perimetrical channel in four sections and receiving the margins of the mirror components comprising said mirror plate, said heating means, said insulating material, and said circuit means, said bracket means further including a continuous flange in at least one section of said channel, said flange having a downwardly and rearwardly inclined inner surface; and an electrical junction box for location within a complemental opening in a wall whereby the base of said box bears against the lower margin of said opening, said box including an integral plate for disposition against said wall, said plate including an offset, horizontally oriented edge to define a clip recess between said edge and said wall whereby engagement of said clip portion on said edge enables said inclined surface to slide downwardly and rearwardly on said edge and thereby seat said bracket means tightly against said wall, the weight of said mirror components being transferred through said plate and said junction box to said wall.
