Abstract

A metallic frame and the assembly from which it is constructed has a header and a jamb and a means to attach them together at a corner of the metal frame. The header and the jamb each have a soffit disposed inwardly from a rabbet and a stop extending substantially perpendicular to and between the rabbet and the soffit. One of either the header or jamb has terminal ends of a first soffit, a first stop, and a first rabbet that generally lie in the same plane with a first corner edge. A rail slot extends through a width of the corresponding first stop and thicknesses of the first soffit and the first rabbet. The other of the header and a jambs has track formed along a second rabbet between a terminal end of a second rabbet and a terminal end of a second stop and second soffit which are cut back and spaced a distance from the terminal end of the second rabbet such that the track and the rail slot are slidingly engageable.

Dependent claims

A metal frame assembly comprising;

a header and a jamb which are operable to be attached to each other at a corner of the metal frame assembly,
said header and said jamb each have a soffit disposed inwardly from a rabbet and a stop extending substantially perpendicular to and between said rabbet and said soffit,
one of said header and said jamb has a first corner end with a straight rail slot set back from a first corner edge and cut through a corresponding first stop, first rabbet, and, first soffit of said one of said header and said jamb wherein first terminal ends of said first soffit, first stop, and first rabbet generally lie in a plane with the first corner edge,
said rail slot extends through a width of said corresponding first stop and thicknesses of corresponding said first soffit and said first rabbet,
said other of said header and said jamb has a second corner end with a second stop and a second soffit having second terminal ends that are set back a distance from a second corner edge which coincides with a rabbet terminal end of a second rabbet of said other of said header and said jamb,
a track is formed along said second rabbet between said rabbet terminal end of said second rabbet and said second terminal end of said second stop, and
said track and said rail slot are slidingly engageable.
