Claim 6

The door jamb of claim 4 wherein both of said dogs and one of said side members have an outer end surface lying in a common plane to provide said bearing surfaces, and wherein the other of said side members extends beyond said common plane to provide a stop for firmly positioning a member secured to and across said channel opening.

Claim 7

The door jamb of claim 5 wherein at least one of said shoulder surfaces and the surfaces of said adjustable mounting plate that bear thereon are provided with a surface roughness that helps to restrain relative sliding motion therebetween when mounting plate flanges are caused to bear upon said surfaces of said side member shoulders.

Claim 8

The door jamb of claim 5 wherein said mounting plate includes a hinge leaf securing portion fixedly connected with said flanges and having a surface facing outwardly of said channel that is spaced from said channel web.

Claim 9

The door jamb of claim 7 wherein said hinge leaf securing portion of said adjustable mounting plate has at least one set of apertures formed therein for receiving threaded fastening members.

Claim 10

The door jamb of claim 1 wherein said adjustable mounting plate is formed with a plurality of different sets of apertures for alternatively receiving threaded fastening members extending through different sets of holes in different hinge leaves, whereby said hole patterns may be preformed in said mounting plate during manufacture of said door jamb, and said mounting plate may be slidably adjusted along said channel during installation of a door thereto, to properly position and appropriate set of said mounting plate holes so as to enable a hinge leaf to be secured thereto at a position determined by the position of a mortise that has previously been formed in a door to be attached to said hinge leaf.

Claim 11

The door jamb of claim 1 wherein said adjustable mounting plate has a length in the direction of the extent of said door jamb that is considerably less than the length of the jamb.

Claim 12

The door jamb of claim 1 wherein said side member bearing surfaces lie in a plane that extends across said channel at an acute angle relative to the jamb, and wherein a cover section is attached to and extends along said jamb and overlies a hinge leaf secured to said mounting plate.

Claim 13

A door frame assembly comprising a head section, a first jamb, a second jamb, means for securing said sections to each other, an adjustable mounting plate, means for adjustably mounting said plate to said first jamb, means for securing a hinge leaf to said mounting plate, and means for fixedly connecting said adjustable mounting plate to said first jamb to thereby lock both said adjustable mounting plate and said hinge leaf attached thereto to said first jamb section, said second jamb being formed with first and second laterally spaced slots opening outwardly thereof and extending substantially throughout the length thereof, and including a strike plate having an extent transverse to the extent of said jamb at least sufficient to span the space between said slots, said strike plate including a pair of flanges projecting into respective ones of said laterally spaced slots for securement of said strike plate to said jamb, said strike plate including an aperture therein for receiving a door bolt, said second jamb having an elongated portion thereof that is laterally positioned in alignment with the aperturE of said strike plate and spaced inwardly of said jamb to provide an unobstructed space between said strike plate and the jamb so that a door bolt protruding through said strike plate aperture will not impinge upon said jamb, and a plurality of elongated cover sections extending along said second jamb and having a first and second mutually spaced flanges projecting therefrom and snapped into said first and second slots respectively, said cover sections of said second jamb having exterior surfaces that are co-planar with the exterior surface of said strike plate to provide a smooth, substantially unbroken exterior surface of said second jamb.

Claim 14

A door frame assembly comprising a head section, a first jamb, a second jamb, means for securing said sections to each other, an adjustable mounting plate, means for adjustably mounting said plate to said first jamb, means for securing a hinge leaf to said mounting plate, and means for fixedly connecting said adjustable mounting plate to said first jamb to thereby lock both said adjustable mounting plate and said hinge leaf attached thereto to said first jamb section, said second jamb being formed with first and second laterally spaced slots opening outwardly thereof and extending substantially throughout the length thereof, and including a strike plate having an extent transverse to the extent of said jamb at least sufficient to span the space between said slots, said strike plate including a pair of flanges projecting into respective ones of said laterally spaced slots for securement of said strike plate to said jamb, said strike plate including an aperture therein for receiving a door bolt, said second jamb having an elongated portion thereof that is laterally positioned in alignment with the aperturE of said strike plate and spaced inwardly of said jamb to provide an unobstructed space between said strike plate and the jamb so that a door bolt protruding through said strike plate aperture will not impinge upon said jamb, and a plurality of elongated cover sections extending along said second jamb and having a first and second mutually spaced flanges projecting therefrom and snapped into said first and second slots respectively, said cover sections of said second jamb having exterior surfaces that are co-planar with the exterior surface of said strike plate to provide a smooth, substantially unbroken exterior surface of said second jamb.
