ABSTRACT:
An escutcheon assembly for a deadbolt lock on a door, and particularly for the interior side of a double cylinder deadbolt lock. The escutcheon assembly generally comprises a tapered collar carried on the deadbolt cylinder (and retained by a flange on the cylinder), plus a decorative face plate substantially covering the cylinder and secured to the collar by a novel clip and set screw mechanism. The collar has an annular groove defining opposing walls, the outermost wall (away from the door) having an inwardly angled surface to taper the groove. The decorative face plate has a clip protruding interiorly therein to a distal end that conforms to the tapered annular groove in the collar (for engagement therewith). A set screw is threaded into the frame opposite the clip and protrudes inward behind the aperture to a distal end that likewise conforms to the tapered annular groove in the collar (for engagement therewith). Insertion of the face plate clip into the groove of the collar and tightening of the opposed set screw into the collar self-centers and affixes the decorative face plate over the cylinder flush against the door with a secure tamper-proof attachment, and the decorative face plate may take virtually any outward shape (rectangular, square, etc.) making it much easier to match inside and outside face plates.
