BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to the installation of windows and doors, and more specifically it relates to a window and door jamb adjustment system for accurately installing windows and doors and providing for later adjustment of the same.
2. Description of the Related Art
The installation of doors and windows has been done for years. Conventional methods of installation require the installer to “guess” where the plasterboard will be so the extension jambs of the window/door are substantially flush to the plasterboard. Unfortunately, since the windows/doors are typically installed before the installation of the plasterboard, errors occur resulting in an extension jamb that is not flush to the plasterboard (e.g. extends out or recess from the plasterboard). If the extension jamb extends out from the plasterboard, the installer must typically plane the extension jamb to be flush with the plasterboard and then refinish the extension jamb. If the extension jamb is recessed with respect to the plasterboard, the installer must then adjust the entire window/door to properly align the extension jamb with the plasterboard. In some situations, it is necessary to completely replace the window extension jambs. All of these follow-up processes are time consuming and costly.
In these respects, the window and door jamb adjustment system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of accurately installing windows and doors.
BRIEF SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of windows and doors now present in the art, the present invention provides a new window and door jamb adjustment system construction wherein the same can be utilized for accurately installing windows and doors.
To attain this, the present invention generally comprises a support member attachable to a building frame, an alignment member slidably attached to the support member and attachable to an extension jamb, a window or door, and a threaded shaft attached to the support member and threadably engaging the alignment member. As the threaded shaft is rotated, the rotational motion is converted to linear motion of the alignment member. As the alignment member is moved with respect to the support member, the extension jamb, a window or door, is correspondingly moved for proper alignment.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and that will form the subject matter of the claims appended hereto.

DETAILED DESCRIPTION OF THE INVENTION
A. Overview
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 12 illustrate a jamb adjuster 10, which comprises a support member 20 attachable to a building frame 18, an alignment member 30 slidably attached to the support member 20 and attachable to an extension jamb 16, a window 12 or door 14, and a threaded shaft 40 attached to the support member 20 and threadably engaging the alignment member 30. As the threaded shaft 40 is rotated, the rotational motion is converted to linear motion of the alignment member 30. As the alignment member 30 is moved with respect to the support member 20, the extension jamb 16, a door 14 or window 12, is correspondingly moved for proper alignment.
B. Support Member
The support member 20 is attachable to a building frame 18 adjacent to the extension jamb 16 of the window 12 or door 14. The support member 20 is preferably comprised of a first segment 22 and a second segment 24 as shown in FIGS. 1 and 3 of the drawings. The second segment 24 of the support member 20 preferably extends substantially orthogonal from the first segment 22 forming an L-shaped structure as best illustrated in FIG. 3 of the drawings.
The first segment 22 is preferably substantially longer than the second segment 24 as best illustrated in FIG. 3 of the drawings. The first segment 22 is substantially straight and substantially flat to allow for fitting between the extension jamb 16 and the building frame 18. The first segment 22 is preferably substantially parallel to the alignment member 30 as illustrated in FIG. 3 of the drawings.
The second segment 24 also preferably includes at least one support aperture 23 for receiving a fastener 50 as shown in FIGS. 1 and 4 of the drawings. The second segment 24 is preferably approximately 2 inches in length to correspond to a conventional 2×4 (or 2×6, etc.) board of the building frame 18.
A first guide 26 and a second guide 28 are preferably attached to the support member 20 that slidably receive the alignment member 30 between thereof as shown in FIGS. 1, 2 and 4 of the drawings. The first guide 26 and the second guide 28 are preferably in opposition to one another and preferably each have an inwardly tapered distal portion as best illustrated in FIG. 4 of the drawings. The first guide 26 and the second guide 28 are preferably substantially flush with respect to an outer surface of the alignment member 30 to prevent interference with the movement of the extension jamb 16 as shown in FIGS. 4 and 8 of the drawings.
C. Alignment Member
The alignment member 30 is slidably attached to the support member 20 and is attachable to an extension jamb 16, a door 14 or window 12. The alignment member 30 further preferably includes at least one alignment aperture 34 for securing the alignment member 30 to the extension jamb 16, the door 14 or window 12 as shown in FIGS. 1 and 2 of the drawings.
The alignment member 30 includes a plurality of alignment slots 32 that receive a portion of the threading 44 of the threaded shaft 40 thereby forming teeth 33 between each of the alignment slots 32 as shown in FIGS. 1 and 2 of the drawings. The teeth 33 may also be formed by extending the same inwardly towards the threaded shaft 40 without having to utilize a plurality of alignment slots 32.
The alignment member 30 is preferably comprised of a substantially straight and substantially flat structure as shown in FIGS. 1 through 4 of the drawings. The upper and lower portions of the alignment member 30 are preferably tapered inwardly to correspond to the distal portions of the guides 26, 28 as best illustrated in FIG. 4 of the drawings.
D. Threaded Shaft
The threaded shaft 40 is rotatably attached to the support member 20 and threadably engages the alignment member 30 as shown in FIGS. 1 through 4 of the drawings. The rotary motion of the threaded shaft 40 is converted to linear motion of the alignment member 30 similar to a rack and pinion. For example, if the threaded shaft 40 is rotated clockwise, the alignment member 30 is pulled outwardly. If the threaded shaft 40 is rotated counter-clockwise, the alignment member 30 is drawn inwardly. It can be appreciated that the rotary motion of the threaded shaft 40 causing linear motion of the alignment member 30 can be changed by simply reversing the threading 44.
The threaded shaft 40 preferably includes an engaging head 42 that allows for the manipulation of the threaded shaft 40 by a conventional tool (e.g. screwdriver, socket, wrench). The threaded shaft 40 has a length of threading 44 that engages the teeth 33 of the alignment member 30 as shown in FIGS. 1 and 2 of the drawings. The threading 44 may have various pitches that correspond to the teeth 33.
A brace 46 is attached to the support member 20 for rotatably receiving the threaded shaft 40 as illustrated in FIGS. 1 through 3 of the drawings. The brace 46 prevents the threaded shaft 40 from moving linearly while allowing the threaded shaft 40 to freely rotate. Various other securing structures may be utilized to rotatably support the threaded shaft 40 with respect to the support member 20. The distal portion of the threaded shaft 40 may also be rotatably supported to the support member 20 using a brace 46 or similar structure.
E. Operation of Invention
The alignment member 30 of each of the jamb adjusters 10 are each attached to an extension jamb 16, a window 12 or door 14 as shown in FIG. 10 of the drawings. The jamb adjusters 10 may be attached at the sides, the upper portion and the lower portion of the extension jamb 16, a door 14 or window 12 to provide sufficient support for the door 14 or window 12. To attach the jamb adjusters 10 to the extension jamb 16, one or more conventional fasteners 50 are extended through the alignment aperture 34 within the alignment member 30 and into the extension jamb 16, a window 12, or door 14.
After the jamb adjusters 10 are properly attached to the extension jamb 16, the window 12 or door 14 with its corresponding extension jamb 16 is positioned within an opening within the building frame 18 where the window 12 or door 14 are to be permanently mounted as shown in FIG. 11 of the drawings. The support member 20 is then attached to the building frame 18 by extending one or more conventional fasteners 50 into the support aperture 23 within the support member 20. The user is then able to rotate the threaded shaft 40 to cause the extension jamb 16 to be extended or recessed with respect to the building frame 18 as shown in FIG. 12 of the drawings. After the plasterboard is secured to the building frame 18 about the window 12 or door 14, the extension jamb 16 can be easily readjusted by simply rotating the threaded shaft 40 to cause the desired movement of the alignment member 30. After the extension jamb 16 is properly positioned within respect to the plasterboard, the extension jamb 16 can be non-movably attached within the building frame 18 with nails or other fasteners 50.
