Abstract
A rectangular glass panel refrigerator door is provided with a mitered frame construction. The door frame has two vertical side frame members and two horizontal cross frame members. Each frame member is generally channel-shaped and has a front wall, an inner sidewall and an outer sidewall which together form a substantially U-shaped channel. The end of each frame member is angled at 45 degrees to form a miter joint with another frame member perpendicular thereto. A right angle corner brace is provided at each miter joint and has one leg lying along the inner wall of the horizontal cross frame member and another leg lying along the inner wall of the vertical frame member. Projecting outwardly from the inner wall of the vertical side frame member is a lug having a threaded aperture therein. A screw is disposed within the outer wall of the horizontal cross frame member with the screw head bearing against the outer wall and with the screw shank extending between the sidewalls of the vertical side frame member and threadingly engaged in the threaded aperture of the lug extending from the inner sidewall of the vertical side frame member. A nut is threadingly engaged on the screw shank and bears against the first leg of the corner member so that the two frame members forming a mi joint are maintained in the miter joint configuration and are prevented from moving relative to one another. A torsion bar hinge assembly is provided with the torsion bar held against rotation at one point in the vertical side frame member by a set screw.
