Devices and methods for mounting door frames
The present invention relates to a door frame, particularly a door frame for a pre-hung door assembly, which is foldable to minimize storage space and to allow for enhanced logistic efficiencies. The door frame contains parallel, spaced apart, vertical jambs and a horizontal header connecting the top ends of the jambs. Each of the jambs and the horizontal header contains a front section and back section that are hingedly joined so that then can be folded on to each other. The hingedly joined front and back sections allow the door fame to be foldable to minimize space occupied during storage.
1. A method for installing a pre-hung door assembly, comprising the steps of:
a. providing a pre-hung door assembly comprising
i. a frame containing a hinge side jamb, a lock side jamb, and a horizontal header jamb, the hinge side and lock side jambs disposed in spaced parallel relation and the header jamb connecting top ends of the hinge side and lock side jambs, wherein each of the jambs is made of a front section and an adjacent back section joined by a hinge configured to allow the front and back sections to be folded, and
ii. a door slab mounted to the hinge side jamb;
b. unfolding the front and back sections of the jambs; and
c. inserting and securing the unfolded pre-hung door assembly into a wall opening.
2. The method of claim 1 , further comprising the steps of removing the front sections of the door jambs, and replacing the front sections of the door jambs with substitute front sections.
3. The method of claim 2 , further comprising the steps of securing the replacement front sections to the back sections.
4. The method of claim 1 , wherein the hinge is one of a bi-fold hinge, a living hinge integral with the associated jamb, and a resilient member.
5. The method of claim 1 , wherein the jambs have a reduced thickness portion forming said hinge.
6. The method of claim 5 , wherein each of the jambs comprises plastic or composite material.
7. The method of claim 1 , wherein the hinge is a tape, a strap, or a bifold hinge.
8. The method of claim 1 , wherein the hinge side jamb and the lock side jamb each comprise polymer composite or wood composite.
9. The method of claim 1 , wherein the hinge is configured to allow each front section to be folded onto the associated back section.
10. The method of claim 1 , wherein the hinge side jamb and the lock side jamb are flat jambs.
11. The method of claim 1 , wherein each back section of each of the hinge side jamb, lock side jamb, and horizontal header has an attached or integral door stop.
12. The method of claim 1 , further comprising the step of replacing each front section with a substitute front section.
13. The method of claim 12 , wherein the substitute front section has a different depth than the front section.
14. The method of claim 12 , wherein the substitute front section is provided as a kit along with the pre-hung door assembly.
15. A method for installing a pre-hung door assembly, comprising the steps of:
a. providing a pre-hung door assembly comprising
i. a frame having a hinge side jamb, a lock side jamb, and a horizontal header jamb, the hinge side and lock side jambs disposed in spaced parallel relation and the header jamb connecting top ends of the hinge side and lock side jambs, wherein each of the jambs is made of a front section and an adjacent back section joined by a hinge configured to allow the front and back sections to be folded, wherein each back section of each of the hinge side jamb, lock side jamb, and horizontal header has an attached or integral door stop, and
ii. a door slab mounted to the hinge side jamb, wherein each front section and associated back section are secured together via an interlock mechanism;
b. unfolding the front and back sections of the jambs; and
c. inserting and securing the unfolded pre-hung door assembly into a wall opening.
16. The method of claim 15 , wherein each front section has a protrusion and each back section has a channel, the protrusion locks with the associated channel and the door stop.
17. The method of claim 16 , wherein each front section has a tongue and each back section has a groove.
18. The method of claim 15 , further comprising the step of replacing each front section with a substitute front section.
19. The method of claim 18 , wherein the substitute front section has a different depth than the front section.
20. The method of claim 18 , wherein the substitute front section is provided as a kit along with the pre-hung door assembly.
