  • Torsionally stiff lightweight refrigerator/freezer door
    Patent number: 4536990
    Abstract: The invention relates to a torsionally stiff door adapted to be mounted for pivotal movement at points on a line parallel to an edge of the door and to be latched at a point along an opposing edge of the door. The door is intended for use in an environment where one side of the door is subject to loading over that surface. The door is also subject to highly directional point loading on the other side of the door. The surface loading and the point loading tend to torsionally bend the door about lines passing through the points, which lines intersect at the latch. The door is fashioned of a pair of spaced apart panels which form respectively one side of the door and the other side of the door.
