Abstract

A door jamb assembly for varied installations in a conventional rough cut door opening disposed in a wall, the assembly including first, second, and third elongated members for mounting on the sides and top of the rough cut door opening to form a pair of door jambs and a header. Two of the elongated members are configured so that they will mate on one end thereof to the first elongated member and on the other end thereof to a portion of the other elongated member between the ends thereof, these two elongated members being essentially mirror images of each other. As a result, a door jamb assembly is provided which can be installed in various width door openings to provide jambs for doors which can be hung with left or right hinges and which open in or out. Additionally, the width of the jambs and header is variable to accommodate walls of different thicknesses.

A door jamb assembly for varied installations in a rough cut door opening in a wall comprising in combination:

a first elongated member for mounting on one side of said rough cut door opening, said first member including a facing portion and a door stop portion positioned at an outer surface of said first member when mounted, said first member having a first end and a second end;
and
second and third elongated members for mounting on the other side and top of said door opening, said second and third elongated members each having first and second ends and comprising a facing portion and a door stop portion positioned on an outer surface thereof when mounted,
said facing portions of said first, second, and third elongated members being variable in width for mounting in door openings cut in walls of different thicknesses, said first, second, and third elongated members each comprising an elongated base section and an elongated movable section, each of said elongated movable sections being movable in relation to the associated said base section to vary the width of said first, second, and third elongated members, a portion of each of said movable sections being captured and slidably retained by a capturing portion of the associated said base sections, sliding of said movable sections within the associated base sections permitting the varying in width of said first, second, and third elongated members, said capturing portion of each of said base sections comprising a longitudinally disposed groove in a longitudinal edge thereof, each of said movable portions comprising a pair of parallel longitudinal tongues of different widths joined by a longitudinal bight portion, either of said tongues being capturable within said groove, capturing of the wider of said tongues providing a facing portion of a width wider than the facing portion provided when the narrower of said tongues is captured by said groove,
said second member for mounting on the top of said door opening when said third member is mounted on said other side of said door opening, said first end of said second member for mating with said first end of said first member, said first end of said third member for selectively mating with a portion of said second member anywhere intermediate said first and second ends thereof,
said third member for mounting on the top of said door opening when said second member is mounted on said other side of said door opening, said second end of said third member for mating with said second end of said first member, said first end of said second member for selectively mating with a portion of said third member anywhere intermediate said first and second ends thereof.
