Patent ID: 8851787

Claim:
A corner joint comprising: a first frame member defining a longitudinal axis and comprising a first corner end, wherein the first corner end comprises a first mitered surface located between an inner squared flange and an outer squared flange, wherein the inner squared flange defines a first plane on one side of the first frame member and the outer squared flange defines a second plane on an opposite side of the first frame member, wherein the first plane and the second plane are parallel to each other, and wherein the inner squared flange comprises a free edge aligned with the longitudinal axis of the first frame member and wherein the outer squared flange comprises a free edge aligned with the longitudinal axis of the first frame member; a second frame member defining a longitudinal axis and comprising a second corner end, wherein the second corner end comprises a second mitered surface, an inner edge spaced longitudinally inwardly from the second mitered surface, and an outer edge spaced longitudinally inwardly from the second mitered surface, wherein the inner edge and the outer edge are oriented perpendicular to the longitudinal axis of the second frame member; wherein the first mitered surface faces the second mitered surface between the inner squared flange and the outer squared flange of the first frame member, wherein the first mitered surface and the second mitered surface define a miter joint plane that forms an acute angle with the longitudinal axis of the first frame member and an acute angle with the longitudinal axis of the second frame member, and wherein the inner squared flange obscures less of the first and second mitered surfaces when the corner joint is viewed from the side of the corner joint on which the inner flange is located than the outer flange obscures when the corner joint is viewed from the side of the corner joint on which the outer flange is located, wherein the free edge of the inner squared flange on the first frame member faces and is aligned with the inner edge of the second frame member to form an inner joint aligned with the longitudinal axis of the first frame member, wherein the free edge of the outer squared flange on the first frame member faces and is aligned with the outer edge of the second frame member to form an outer joint aligned with the longitudinal axis of the first frame member.
