Door system with interlocking panels

摘要

A door is formed by latch and hinge panels which can be attached without fasteners or welding. Each of the panels is formed of a unitary piece of sheet metal and includes a rectangular face member, a side flange extending substantially perpendicularly from the face member along one of its side edges, a first latch formed along a free lateral edge of the side flange remote from the face member, a second latch formed along the opposite side edge of the face member and end flanges extending substantially perpendicularly from the face member along the end edges. The first latch of each panel is secured to the second latch of the other panel such that the panels are secured and form the door, with latches being located at diametrically opposite corners of the door. An insulating core member is located between the panels.
