Abstract
Corner joints and methods of forming corner joints are described herein. The corner joints may provide the appearance of a mortise and tenon joint on both the exterior and interior surfaces of the corner joint, but include a mitered connection within the joint. Structures including at least one of the corner joints are also described.
Claims24
A corner joint comprising:
- a first frame member 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;
- a second frame member comprising a second corner end, wherein the second corner end comprises a second mitered surface, an inner edge spaced inwardly from the second mitered surface, and an outer edge spaced inwardly from the second mitered surface, wherein the inner edge and the outer edge are oriented perpendicular to a longitudinal axis of the second frame member;
- wherein the first mitered surface faces the second mitered surface;
- wherein a free edge of the inner squared flange on the first frame member faces the inner edge of the second frame member,
- wherein a free edge of the outer squared flange on the first frame member faces the outer edge of the second frame member.

A corner joint comprising:
- a first frame member comprising a first corner end that comprises a first corner end opening, wherein the first corner end further comprises a first mitered surface located between an inner squared flange and an outer squared flange;
- a second frame member comprising a second corner end that comprises a second corner end opening, wherein the second corner end further comprises a second mitered surface, an inner edge spaced inwardly from the second mitered surface, and an outer edge spaced inwardly from the second mitered surface, wherein the inner edge and the outer edge are oriented perpendicular to a longitudinal axis of the second frame member;
- a corner key comprising a first leg and a second leg, wherein the first leg is located in the first corner end opening and the second leg is located in the second corner end opening;
- and
- adhesive material located between the inner squared flange and the corner key and adhesive material located between the outer squared flange and the corner key;
- wherein the first mitered surface faces the second mitered surface;
- wherein a free edge of the inner squared flange on the first frame member faces the inner edge of the second frame member,
- wherein a free edge of the outer squared flange on the first frame member faces the outer edge of the second frame member.

A method of forming a corner joint, the method comprising:
- forming a first mitered surface on a first corner end of a first frame member, wherein the first mitered surface is located between an inner squared flange and an outer squared flange at the first corner end of the first frame member;
- forming a second mitered surface on a second corner end of the second frame member;
- forming an inner edge spaced inwardly from the second mitered surface and an outer edge spaced inwardly from the second mitered surface, wherein the inner edge and the outer edge are oriented perpendicular to a longitudinal axis of the second frame member, and wherein the second mitered surface is located between the inner edge and the outer edge;
- attaching the first frame member to the second frame member such that the first mitered surface of the first frame member and the second mitered surface of the second frame member face each other within the corner joint, a free edge of the inner squared flange on the first frame member abuts the inner edge of the second frame member, and a free edge of the outer squared flange on the first frame member abuts the outer edge of the second frame member.
1 more element
A structure comprising a first frame member and a second frame member attached to each other at a corner joint, wherein the corner joint comprises:
- a first mitered surface located between an inner squared flange and an outer squared flange on a first corner end of the first frame member;
- a second mitered surface located on a second corner end of the second frame member, an inner edge spaced inwardly from the second mitered surface on the second corner end of the second frame member, and an outer edge spaced inwardly from the second mitered surface on the second corner end of the second frame member, wherein the inner edge and the outer edge are oriented perpendicular to a longitudinal axis of the second frame member;
- wherein the first mitered surface faces the second mitered surface;
- wherein a free edge of the inner squared flange on the first frame member faces the inner edge of the second frame member,
- wherein a free edge of the outer squared flange on the first frame member faces the outer edge of the second frame member.
