Abstract

A door frame employs extruded aluminum jamb moldings, including extruded jambs, or jamb cover moldings in combination with jamb substrates. The extruded aluminum molding includes a mounting fin kerf. The kerf is generally boot-shaped, having an inwardly-disposed foot portion and an opening having an ankle-shaped cross-section. The mounting fin can be generally rigid, such as an extruded aluminum fin or a generally rigid polymeric fin. The kerf, in combination with the mounting fin, which has a bulbous rigid base, facilitates locking the fin in an erect orientation at about 75 degrees to about 90 degrees relative to the jamb body or the jamb substrate. The kerf/fin combination further provides improved ease of release of the fin from the erect orientation and facilitates rotating/retracting the fin into contact with the jamb body or jamb substrate.

Dependent claims

A door jamb, having a length, and being adapted to be received, as part of a door frame, into a rough opening in a building, said door jamb comprising:

(a) a jamb body having a length and comprising
(i) a first side facing toward such rough opening,
(ii) a second side facing away from such rough opening,
(iii) an outer side facing outwardly of such building, and
(iv) an inner side facing inwardly into such building;
(b) a nosing, attached to said jamb body and extending outwardly of said building, away from said outer side of said jamb body, said nosing having a length;
and
(c) a single elongate mounting fin kerf extending along the length of said nosing, said elongate mounting fin kerf having a boot-shaped cross-section defined by an inwardly-disposed foot portion having a generally foot-shaped cross-section, said foot portion having a toe end and a heel end, said kerf further comprising a slot-shaped opening portion having an ankle-shaped cross-section at the heel end of the foot portion, said slot-shaped opening portion leading from the foot portion out of the kerf and into outside ambient environment, the slot-shaped opening portion having a toe side and a heel side, the heel side of said slot-shaped opening portion extending from the foot portion to the outside ambient environment along a generally straight line.

5 more elements

A door jamb assembly, having a length, and being adapted to be received, as part of a door frame, into a rough opening in a building, said door jamb assembly comprising:

(a) a jamb body having a length, and comprising
(i) a first side facing toward such rough opening,
(ii) a second side facing away from such rough opening,
(iii) an outer side facing outwardly of such building, and
(iv) an inner side facing inwardly into such building;
(b) a nosing attached to said jamb body and extending outwardly of said building, away from said outer side of said jamb body, said nosing having a length;
(c) a single elongate mounting fin kerf extending along the length of said nosing, said mounting fin kerf having a slot-shaped opening defined by a heel side wall and a toe side wall;
and
(d) an elongate generally rigid mounting fin in the kerf, said mounting fin having a base portion received in the kerf, and a distal side remote from said base portion, said mounting fin being
(i) movable to a retracted orientation wherein the distal side of said mounting fin is located generally proximate the second side of said jamb body, and
(ii) movable to an erected orientation wherein the distal side is displaced from the second side of said jamb body,
and wherein said mounting fin can be locked in the erected orientation by interference between
(i) said base portion of said mounting fin and
(ii) said heel side wall and said toe side wall of said mounting fin kerf,
said mounting fin, when so locked in said mounting fin kerf, in the erected orientation, defining a minimum angle of about 75 degrees to about 90 degrees with respect to the second side of said jamb body.

12 more elements

A door jamb assembly, having a length, and being adapted to be received, as part of a door frame, into a rough opening in a building, said door jamb assembly comprising:

(a) a jamb body having a length, and comprising
(i) a first side facing toward such rough opening,
(ii) a second side facing away from such rough opening,
(iii) an outer side facing outwardly of such building, and
(iv) an inner side facing inwardly into such building;
(b) a nosing attached to said jamb body and extending outwardly of said building, away from said outer side of said jamb body, said nosing having a length;
(c) a single elongate mounting fin kerf extending along the length of said nosing, said mounting fin kerf having a slot-shaped opening defined by a heel side wall and a toe side wall;
and
(d) an elongate generally rigid mounting fin in the kerf, said mounting fin having a base portion and a distal side,
(i) said mounting fin being movable to, and lockable in, an erected orientation wherein the distal side of said mounting fin is displaced from the second side of said jamb body, and
(ii) said mounting fin being adapted to be unlocked from the erected orientation and moved to a retracted orientation wherein a portion of said mounting fin can lie against the second side of said jamb body.

8 more elements

A door jamb assembly, having a length, and being adapted to be received, as part of a door frame, into a rough opening in a building, said door jamb assembly comprising:

(a) a jamb body having a length, and comprising
(i) a first side facing toward such rough opening,
(ii) a second side facing away from such rough opening,
(iii) an outer side facing outwardly of such building, and
(iv) an inner side facing inwardly into such building;
(b) a nosing attached to said jamb body and extending outwardly of said building, away from said outer side of said jamb body, said nosing having a length;
(c) a single elongate mounting fin kerf extending along the length of said nosing, said mounting fin kerf having a slot-shaped opening defined by a heel side wall and a toe side wall;
and
(d) an elongate generally rigid mounting fin in the kerf,
(i) said mounting fin being movable to, and lockable in, an erected orientation wherein a distal side of said mounting fin is displaced from the second side of said jamb body, and
(ii) said mounting fin being adapted to be unlocked from the erected orientation and rotated toward the second side of said jamb body,
the unlocking of said mounting fin from the erected and locked orientation being effected by pulling said mounting fin in a direction generally perpendicularly away from the second side of said jamb body.
