Metal corner member for strengthening the intersection of two adjacent exterior structural wall members forming an exterior structural corner

Abstract

A flexible bullnose corner member for covering an external corner intersection of two adjacent wall members, generally comprising a right side flange, a left side flange, a bullnose arcuate edge section, left and right shoulder stops connecting the respective flanges to the edges of the arcuate edge section, and an adjustable bullnose flange angle. Also described is an adjustable radius bullnose corner member having an architecturally radiused curvature along the length of its outer surface for mounting over and strengthening the structural integrity of two adjacent corner wall members of a structure and for receiving on its outer surface a wall plastering material such as stucco or the like. Perforations or other structural features may be employed to assist in retaining the stucco or other finishing material on the bullnose surface. Also disclosed is an L-shaped corner member for strengthening the intersection of two adjacent wall members forming a corner.

I claim: 
     
         1 . A metal corner member for attaching to and strengthening abutting, first and second adjacent exterior wall members that meet in an exterior corner of a structure, the abutting wall members each comprising an outer face, an inner face, opposed top and bottom edges and opposed side edges, said edges forming a wall member thickness between said outer and inner wall member faces, wherein one of said opposed side edges of said first wall member abuts up against the inner face of said second wall member adjacent one of said opposed side edges of said second wall member, said adjacent side edge of said second wall member being aligned to be flush with said outer face of said adjacent first wall member to form a corner edge, the corner member comprising:
 a. a first elongate, planar flange section having top, bottom, right side and left side edges, a flat outside face, and a flat inside face, and   b. a second elongate, planar flange section having top, bottom, right side and left side edges, a flat outside face, and a flat inside face,
 wherein the first elongate, planar flange right side edge is joined to the second elongate, planar flange left side edge to form an elongate corner seam having a flange intersection angle that can range from between about 60 degrees to about 120 degrees, 
 wherein the first planar flange extends away from the seam along a first plane, 
 wherein the second planar flange extends away from the seam along a second plane, 
 wherein the corner seam does not extend outside of either the first plane or the second plane, said metal corner member not defining a bullnose corner, said metal corner not comprising any raised surface features along the corner seam, and 
 wherein the flat inside faces of the planar flange sections of the corner member being attachable over the corner edge. 
   
     
     
         2 . The corner member of  claim 1  wherein the first and/or second elongate flange section contain one or more perforations for receiving nails.
