ABSTRACT:
A panel assembly that may be used in doors, particularly hollow metal doors, and other types of panels such as interior and exterior walls, room partitions, and the like. The panel assembly exemplified by a hollow or filled metal door is constructed from a deep pan and a shallow pan made from unitary pieces of sheet metal sheet and each pan includes top, bottom, and two opposing side flanges extending from rectangular face members. The flanges of the deep pan are substantially perpendicular to its rectangular face member and higher than those of the shallow pan. Side flanges of one of the pans have first latch members formed along free side edges of their side flanges remote from their respective face member and side flanges of the other pan have second mating latch members formed along free side edges of their side flanges remote from their respective face members. The top and bottom flanges have doubly bent edges that are formed along free side edges of their top and bottom flanges remote from their respective face members. The free side edges of the top and bottom flanges are doubly bent so as to be in overlapping abutting relationship or shiplapped with corresponding ones of the front and rear plans. The first latch member of each pan is secured to the second latch member of the other pan such that the pans are secured and form the panel.
