Description
ADJUSTABLE DOOR FRAME
FIELD OF THE INVENTION
The present invention relates to door frames and more particularly to adjustable metal door frame assemblles.
BACKGROUND
In the lnstallation of ad~ustable width metal door frame assemblies, it is conventional to put in place the frame elements, eg. the ~ambs and the header, to ad~ust them to the thickness of the wall and then to fasten them to the wall using screws through the door casing into the wall. This is a relatively complex procedure when compared with the installation of a fixed width door frame. In the resultant frame, the screws through the casing are aesthetically undesirable so it is common practice to install caps over the casing. This is a further step that has to be taken in the installation and also requires six additional pieces in the overall frame assembly.
It is an aim of the present invention to provide an improved ad~ustable door frame that is relatively simple both in constructlon and installation and that does not suffer from the aesthetic problems of the prior art. The invention is also concerned with a .
- . -.
method of installing the frame.
SUMMARY
According to one aspect of the present invention there is provided a door frame comprising two jambs and a header, means for connecting the jambs to opposite ends of the header to form a substantially rigid frame, each jamb and the header comprising:
two elongate components with respective overlying flanges;
a plurality of stiffener means secured to inner sides of the overlapping flanges of the two components for maintaining the flanges parallel to one another, each stiffener means comprising;
a transversely oriented channel secured to one of the components;
a transversely oriented rail secured to the other of the components, the rail being engaged slidably in the channel; and fastener elements extending through the respective channels into the associated rails securing the channels to the rails to prevent sliding movement of the rail along the channel, the fastener means ~eing accessible solely from the inner side of the component.
According to another aspect of the present invention there is provided a door frame of the type comprising two jamb elements, a header element independent from the jamb elements and means for connecting the jamb elements and the header element into a substantially rigid frame, the frame being an adjustable width frame in which each element comprises first and second elongate components with respective overlapping flanges, each element including a guide means comprising plural elongate rails secured to an inner side of the . ~,, i : .. .. .

DETAILED DESCRIPTION
Referring to the accompanying drawings, there is illustrated a door frame 10 that includes two ~ambs 12 and 14 and a header 16. One of the iambs will be a hinge ~amb and the other a strike jamb. Which jamb is on which side will depend on whether the door is to be mounted right handed or left handed.
Each of the frame elements includes an integral , door stop 18 providing a fixed depth door rebate 19. The frame elements provide a frame casing 20 that extends over the wall ad;acent the door opening in which the frame is installed. At the upper corners of the frame, the casing components of the ~ambs and header meet at a mitred corner 22.
As illustrated most particularly in Figures 2 and 3, each of the frame elements (that is each of the ~ambs and the header) includes two components 24 and 26.
The component 24 is an elongate sheet metal element with two right angle bends 28 and 30 ad~acent one of its edges providlng two flanges 32 and 34 and a door casing flange 36 whlch ends at a right angle bend 38. This provides a flange 40 extending part way across the inside face of a door opening and terminating in an outwardly directed lip 42.
The component 26 is similarly shaped but inclùdes an offset door stop section 44 in the form of a shallow channel lnto which the lip 42 pro~ects.
As illustrated most particularly in Figure 3, an L-shaped base clip 46 is spot welded to the flange 40 of each of the ~amb components 24 and 26. The clip has two punched screw holes 48. When the frame is mounted in a door opening, the base clips extend over the face of .
- . . , ~, 2~
the drywall or other paneling 50 and are held in place with screws through the screw holes 48 lnto the stud.
As illustrated most particularly in Figure 4, the upper corners of the frame are held together with sheet metal corner clips 54. Each clip is spot welded to a respective ;amb component end-engages the end of an associated header component through a slot 56 in the flange 34 of the header and a projection 58 in the clip.
Thls arrangement is more fully described in Canadian Patent 940,777 issued January 29, 1974 to Pero Sales 1966 Limlted.
Figure 4 also lllustrates a wall adjuster 60 that ls fixed to the inside of the door stop 44 of the component 26 of each door jamb. The wall adjuster is located a short dlstance below the underside of the header in the completed frame. Each adjuster includes a æhort channel sectlon 62 threaded onto a screw 64 that ls rotatably mounted on the frame component by a bracket 66.
An opening ln the face of the door stop provides access to the screw 80 that lt can be rotated to extend and retract the wall adjuster.
Each of the frame elements is e~ulpped wlth stiffeners 68. These include four stlffeners for each ~amb and two for the header. The construction of the .. . . . : . , :

stiffeners is lllustrated most particularly in Figures 5, 6 and 7.
Each stiffener 68 includes a rail 70 fixed to the frame component 24 and a channel 72 fixed to the frame component 26. The rail 70 includes a channel section 74 and a flange 76 extending from one side of the channel section. The flange is spot welded to the flange 40 of the component 24 with the rail extending widthwise across the frame element. The channel 72 has a similar channel section 78 that fits slideably over the section 74. A flange 80 pro~ects from the channel section 78 in a direction opposite the flange 76. Flange 80 is spot welded to the flange 40 of the component 26. With this arrangement, the rail 70 and the component 24 are captured between the channel 72 and the component 26.
Engagement of the llp 42 on the component 24 wlth the end of the door stop 44 ~revents the separatlon of the two components.
Two screw holes 82 are formed ln the channel sectlon 78 so that self tapping screws can be driven through those holes into the rail channel section 74 to fix the channel 72 and rail 70 together in an adjusted position corresponding to a particular wall width.
To lnstall a door frame according to the , . . - ; - -,: . . ~ -., . . : , -., ~ . ~ . .. .. .
invention, the thickness of the wall is measured around the door opening. The three frame elements are laid flat and ad~usted so that the spacing between the flanges 32 corresponds to the wall thlckness. Self tapping screws are then driven through the channel and rail of each stiffener so that the two components 24 and 26 of each frame element are fastened together. The wall adjuster screws are then rotated to bring the adjuster channels 62 up a~ainst the back of the jamb.
one of the ~ambs is positioned in the door opening and pushed tight against the stud. The header is then held at an angle to the installed iamb and the corner clips are engaged but not locked. The remaining ~amb is then held at an angle to the free end of the header and its corner clips are engaged but not locked.
The header and ~amb assembly is then lifted into position in the door opening to close the mitres at the top corners. The mitres are locked by tapping the top side of each ~amb towards the header. The lnstalled frame is then squared, the base clips are screwed to the studs on either side of the door frame and the wall adjusters are tightened to anchor the frame firmly to the wall and to ensure that lt is properly aligned.
It will thus be seen that the installation ... .
