Abstract
Abstract A door-frame assembly for mounting in the door opening of a wall wherein the weight of the door mounted thereon is carried on concealed support members rather than the jambs. The assembly has a pair of rigid support members mounted on either side of the door. In the preferred case, plates, secured to the support members, face the door opening and are spaced generally such that the hinges of the door can be fastened directly thereto through openings in the jambs. The jambs can be of the double rabbet type including door stops having a channel facing the door opening and which contain apertures through which screws or other fastening means can be placed to secure the jambs to the plates. The channel is provided with a snap-in, flexible insert such that the fastening means are concealed. The door stop can also have a channel which faces the door side of the assembly and in which is carried a flexible insert to act as a weather seal or gasket. The header section, which serves also to space the support members, can be of either the same configuration as the jambs or can be comprised of a fascia strip which snaps into a partition cap. The support members can be adjusted vertically to accommodate various door height openings. This is accomplished by means of vertical slots located close to each end of the support through which extend fastening means which are slidable in the slots and adjustably tightenable in lower or upper brackets mounted on the floor or wall supporting members respectively. The sides of the jambs which embrace respective sides of the wall adjacent the door openings are equipped with in-turned legs which engage the wall surfaces and which contain longitudinal passageways into which can be inserted dowel pins to allow for splicing thereof.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
223 words
A door-frame assembly for mounting in a door opening of a wall and between upper and lower structural members comprising: a. a rigid support member mounted on each side of said door opening between opposite sides of said wall; b. means anchoring said support members to said upper and lower structural members; c. hinge supporting means secured directly to at least one of said support members; d. a pair of jambs mounted on each side of said door opening, said jambs being generally channel-shaped in cross section, having a web and a pair of limbs extending laterally from each end of said web and embracing opposite sides of said wall adjacent said opening, at least one of said jambs having at least one opening therein so as to allow securing of at least one hinge leaf to said hinge supporting means; and e. a header section mounted horizontally across the top of said opening between said jambs, portions of the ends of said header section extending beyond the webs of said jambs and abutting said support members whereby any moment caused by the weight of a door mounted on said assembly and acting parallel to said header section is transmitted through said header section acting in compression from the support member on which said door is mounted directly to the opposing support member.
Claim 2
Dependent Claim
223 words
A door-frame assembly for mounting in a door opening of a wall and between upper and lower structural members comprising: a. a rigid support member mounted on each side of said door opening between opposite sides of said wall; b. means anchoring said support members to said upper and lower structural members; c. hinge supporting means secured directly to at least one of said support members; d. a pair of jambs mounted on each side of said door opening, said jambs being generally channel-shaped in cross section, having a web and a pair of limbs extending laterally from each end of said web and embracing opposite sides of said wall adjacent said opening, at least one of said jambs having at least one opening therein so as to allow securing of at least one hinge leaf to said hinge supporting means; and e. a header section mounted horizontally across the top of said opening between said jambs, portions of the ends of said header section extending beyond the webs of said jambs and abutting said support members whereby any moment caused by the weight of a door mounted on said assembly and acting parallel to said header section is transmitted through said header section acting in compression from the support member on which said door is mounted directly to the opposing support member.
