Claims
- 1. 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 flange of the first component, plural elongate channels secured to an inner side of the flange of the second component and engaging slidably over the respective rails for free sliding movement therealong, the rails and the channels being oriented widthwise of the frame for relative movement thereof in response to adjustment of the width of the frame element, and fastener elements extending through the respective channels to engage the associated rails securing the channels to the rails to prevent relative widthwise sliding movement of the channels and the rails whereby the width of each element may be fixed before installation of the frame.
- 2. A door frame according to claim 1 wherein the first and second components of each element are sheet metal sections.
- 3. A door frame according to claim 2 wherein the flange of each second component comprises and offset flange section providing a door stop.
- 4. A door frame according to claim 3 wherein the flange of each first component comprises a terminal lip projecting outwardly into the offset flange section of the associated second component.
- 5. A door frame according to claim 1 wherein each rail comprises a first sheet metal channel section with parallel first and second edges oriented widthwise of the frame and a rail mounting flange along the first edge, the rail mounting flange being secured to the first component.
- 6. A door frame according to claim 5 wherein each channel comprises a second sheet metal channel section with parallel first and second edges oriented widthwise of the frame and a channel mounting flange along the first edge of the second sheet metal channel section and projecting therefrom in a direction opposite the rail mounting flange of the associated rail, the mounting flange of the channel being secured to the second component, the rail mounting flange extending between the second component and the second edge of the channel.
- 7. A door frame according to claim 6 wherein the means for securing the channel to the rail comprise self tapping screws.
- 8. A door frame according to claim 7 including screw openings in the channel to receive the self tapping screws.
- 9. A door frame according to claim 1 including a base clip secured to each jamb element for attaching a bottom end of the element to a wall.
- 10. A door frame according to claim 9 including wall adjusters mounted on the second component of each jamb element adjacent an end thereof remote from the base clip, each wall adjuster including wall engagement means and means for urging the wall engagement means against a wall confronting the flanges of the jamb components.
- 11. A door frame comprising two jambs and a header, means for connecting the jambs to opposite ends of the header to from 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 channel to the rail to prevent sliding movement of the rail along the channel, the fastener means being accessible solely from the inner side of the component.
