## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims priority to U.S. provisional patent application Ser. No. 60/019,986 filed on Jan. 9, 2008, the disclosure of which is expressly incorporated by reference herein in its entirety.


FIELD OF THE INVENTION
The present invention relates to a leveling device for leveling cabinetry and more particularly for levelling one or more units of base cabinetry.
BACKGROUND OF THE INVENTION
Proper installation of base cabinets is critical to the overall look, function and life of newly installed cabinets. Since the advent of modern cabinet fabrication techniques, cabinet installers have searched for better, faster, more convenient ways to install cabinets. Those experienced in the art, for many reasons, have relied on tapered, wooden shims to level, plumb and support base cabinets. There are numerous drawbacks associated with the use of shims. For example, they are cumbersome, they don't allow precise adjustment; and they require trial and error to use. They are very time-consuming and require the installer to work on his knees and elbows using a pry bar in one hand and a shim in the other. Shims absorb water which may wick up into the cabinets, causing damage and/or promoting the growth of mold.
Over the years, there have been many attempts to design a more functional, faster device to install (level and plumb) cabinets—one that would eliminate the use of wooden shims. The marketplace today is full of such leg-leveling devices. Examples of such devices include the various cabinet levelers available from Specialty Supplies, Inc. (www.specialtysupplies.com). Most of these devices achieve the desired results but they significantly increase installation time and angst. As a practical matter, the devices that are commercially available today are seldom used. They are difficult to use even for the most experienced installer and practically impossible for the average do-it-yourselfer homeowner.
The main reason professional installers do not like to use cabinet leveling devices is that they are very time consuming and difficult to work with. Most of these devices must be screwed to each inside corner of each cabinet and then adjusted individually while the cabinet is turned over on its top. The biggest problem with these devices that are attached to the inside of the cabinet carcass is that they are completely inaccessible from the outside of the cabinet. Thus, the cabinets are flipped over and set in place to evaluate if further adjustments need to be made. Most often repeated adjustments are necessary and require repeated removal and flipping of the cabinets in order to make these additional adjustments. The entire trial and error process is tedious, time-consuming and costly.
Another type of device that has been developed is disclosed in U.S. Patent Application Publication No. US2006/0124810 A1, naming Peter Cotto as inventor (“Cotto Publication”). While the device disclosed in the Cotto Publication has some advantageous features, it still suffers from numerous drawbacks, including the need for drilling access holes through the bottom shelf of the cabinet; the device is only accessible from the interior of the cabinet; it only levels one cabinet at a time; it requires removal of all internal shelving/drawers prior to installation; and it requires precise alignment with the drilled hole.
In spite of the many attempts to develop a better device and method, installers today still most frequently use tapered, wooden shims for installation. Yet they continue to seek a better, faster and more convenient solution that would get them off their knees and speed up the cabinet installation process. As described below, the present invention satisfies each of these needs in the art.
SUMMARY OF THE INVENTION
In accordance with the present invention, a novel device for cabinet installation has been developed. The device of the present invention is completely accessible from the outside of the cabinet, even when other cabinets are placed beside it. Additionally, it is easy to install and adjust with a standard Allen head tool. Adjustment is quick, easy and extremely precise. The device attaches to two adjacent cabinets with a pressure-fit and does not require screws or drilling of holes in the cabinet or flipping the cabinet over. Moreover, because the device is attached to two adjacent cabinets, it serves to level/plumb two cabinets at a time, which saves time and costs, as well as to space the cabinets. Because the device is easily accessible throughout the entire installation process from the outside of the cabinets, the ease of use and adjustment capabilities are remarkable.
In one embodiment, the leveling device of the present invention includes a first channel for receiving a first cabinet sidewall, a second channel for receiving a second cabinet sidewall, an intermediate section connecting the first and second channels, and an adjustable threaded member received through a threaded opening in the intermediate section for providing leveling adjustability to the device. The device may also include inward projections such as dimples in the first and/or second channels to provide a friction fit with cabinet sidewalls.
A variety of materials are suitable for making the leveling device of the present invention. These include aluminum, composite plastics, etc. Moreover, the material is something that should be workable with milling, extruding or stamping.
Because the sidewalls of cabinets vary from one manufacturer to another, the leveling device of the present invention is designed to fit the differing cabinet sidewall dimensions. The most standard dimension is 1⁄2′′ plywood, but other dimensions ranging from 3⁄8′′ to 5⁄8′′ to 3⁄4′′ plywood may be accommodated.

These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims and accompanying drawings wherein:
FIG. 1 is a perspective view, partially broken away, of a cabinet/counter combination showing the devices of the present invention in place;
FIG. 2 is a front view of two adjacent cabinet walls with devices of the present invention in place; and
FIG. 3 is an exploded perspective view of an alternative embodiment of the present invention.
FIG. 4 is a front view of two adjacent cabinet walls with an alternative device embodiment in place at the bottom of the cabinet.



DETAILED DESCRIPTION
Referring now to the drawings, FIG. 1 shows a portion of a run of base cabinets 10 of the type typically installed in homes and/or businesses and which are finished with a countertop 12. Based on the unevenness of the flooring upon which the base cabinets sit, it is necessary to provide leveling and plumbing of the cabinets 14 prior to installation of the countertop 12. In accordance with the present invention, several leveling devices 16 are shown in place in FIG. 1. As can be seen with reference to FIGS. 1 and 2, device 16 includes two channels 18A and 18B, along with an intermediate connecting section 20. Connecting section 20 has a threaded through hole 22 which receives an adjustable threaded member 24. Threaded member 24 preferably has a foot pad 26 at the base thereof which rests on the floor surface and a structure at the upper end thereof, such as an Allen-type female opening 28, for securing a turning device. While the device 16 is shown with an Allen-type female opening, other structures such as flat and Phillips head screw driver structures may also be used. Allen-type opening 28 receives the end of an Allen-type wrench 30 which is turned in the clockwise direction to raise the leveling device 16 relative to the floor 31. As shown in FIG. 1, the Allen wrench 30 is an elongated member which can be activated from the top of the base cabinets and is easily accessible between the side walls 32, 34 of two adjacent cabinets.
As will be understood with reference to FIG. 1, by using the leveling device 16 of the present invention at each of the four corners of a cabinet 14 and by connecting two adjacent cabinets 14A, 14B, the device simplifies the process of leveling adjacent cabinets side-to-side and front-to-back to readily position the cabinets for receiving the installation of countertop 12. Based on the design of the device, the device 16 provides both a leveling action and a spacer action between the adjacent cabinet sidewalls 32 and 34. As shown in FIGS. 1 and 2, an inverted leveling device of the present invention may be used at the top of the cabinets to both retain them in position with the required spacing and to provide a guide hole for Allen wrench 30. It may be preferable to have the receiving channels 18A and 18B of slightly different dimensions. In that regard, as shown in FIG. 2, receiving channel 18A is slightly wider than receiving channel 18B. In addition, receiving channel 18B has inwardly extending projections such as “dimples” 36 to provide a strong friction fit to sidewall 34 of cabinet 14. By using a second leveling device 16 at the top edge of adjacent cabinets, the friction fit is on the adjacent sidewall 32 of cabinet 14 and thus both cabinets are rigidly secured together through the use of dual leveling devices 16. Device 16 may have inwardly extending projections such as dimples 36 in both channels 18A and 18B.
With reference to FIG. 3, there is shown an alternative embodiment of the present invention wherein threaded member 24 does not include a foot pad 26, but rather the device includes a separate component in the form of a base plate 38 which has indentations 40 for registering and receiving the distal end of threaded member 24.
In an alternative embodiment, FIG. 4 shows a leveling device 16 in all respects the same as that shown in FIG. 2, but also including a base wall 42 that partially encloses cavity 44. Base wall 42 also includes threaded opening 46 for receiving threaded member 24 therethrough.
While the foregoing description has set forth preferred embodiments of the present invention in particular detail, it must be understood that numerous modifications, substitutions and changes can be undertaken without departing from the true spirit and scope of the present invention as defined by the ensuing claims. The invention is therefore not limited to specific embodiments as described but is only limited as defined by the following claims.
