Abstract
An adjustable door frame includes a latch jamb, a hinge jamb, two closure jambs, a base header and a closure header, each of which is unitarily formed. The jambs and headers are adjustably connected to accommodate variations in wall thicknesses. Each of the hatch jamb, hinge jamb and base header has a trim section overlying the wall, an inside section extending into the doorway opening, a door abutment section extending perpendicularly into the doorway and a pair of parallel flanges extending perpendicularly from the abutment section and defining a slot. Each of the closure jambs and closure header has a trim section for overlying the opposite wall surface, an inside section extending into the doorway and a tongue section. The slots frictionally engage the tongue sections.
Claims27
An adjustable door frame, comprising:
- a first member unitarily formed without any undercut portions, said first member including
- a first trim section for overlying a wall surface adjacent a doorway opening in a wall,
- a substantially planar first inside section extending substantially perpendicularly in a single plane from said first trim section for extending into the doorway opening,
- a first door abutment section extending substantially perpendicularly from said first inside section at an end thereof remote from said first trim section in a direction parallel to and opposite to said first trim section, and
- a pair of parallel, substantially planar flanges extending substantially perpendicularly from said first abutment section at an end thereof remote from said first inside section in a direction parallel to and opposite to said first inside section, said flanges defining a slot therebetween having a constant width along an entire length said first abutment section to free ends of said flanges;
- and
- a second member unitarily formed without said second member including
- a second trim section for overlying a wall surface adjacent an opposite side of the doorway opening in the wall,
- a substantially planar second inside section extending substantially perpendicularly from said second trim section in a single plane for extending into the doorway opening toward and adjacent to said first inside section, and
- a tongue section extending from said second inside section in a single plane at an end thereof remote from said second trim section as a coplanar extension thereof along an entire length of said tongue section, said slot receiving and frictionally engaging said tongue section;
- whereby engagement of said tongue section in said slot provides an adjustable connection of said first and second members to compensate for varying wall thickness, and said first and second members can be engaged by sets of cooling rolls after being formed in extrusion heads.

An adjustable door frame, comprising:
- a first frame assembly having a latch jamb, a hinge jamb and base header each being unitarily formed without any undercut portions and including
- a first trim section for overlying a wall surface adjacent doorway opening in a wall,
- a substantially planar first inside section extending substantially perpendicularly in a single plane from said first trim section for extending into the doorway opening,
- a first door abutment section extending substantially perpendicularly from said first inside section at an end thereof remote from said first trim section in a direction parallel to and opposite to said first trim section, and
- a pair of substantially planar flanges extending substantially perpendicularly from said first abutment section at an end thereof remote from said first inside section in a direction parallel to and opposite to said first inside section, said flanges defining a slot therebetween having a constant width along an entire length thereof from said end of said first abutment section to free ends of said flange;
- and
- a second frame assembly having two closure jambs and a closure header each being unitarily formed without any undercut portions and each including
- a second trim section for overlying a wall surface adjacent an opposite side of the doorway opening in the wall,
- a substantially planar second inside section extending substantially perpendicularly form said second trim section in a single plane for extending into the doorway opening toward and adjacent to the respective inside section, and
- a tongue section extending from said second inside section in a single plane at an end thereof remote from said second trim section and as a coplanar extension thereof along an entire length of said tongue section, said slot receiving and frictionally engaging the respective tongue section;
- whereby engagement of said tongue sections in said slots provides an adjustable connection of said first and second frame assemblies to compensate for varying wall thickness, and said headers and jambs can be engaged by sets of cooling rolls after being formed in extrusion heads.
