This Application is a Divisional of U.S. patent application Ser. No. 11/017,245 filed Dec. 20, 2004 currently still pending, the entire contents of which are herein fully incorporated by reference.
TECHNICAL FIELDThis invention relates generally to countertops and their installation. More particularly, it relates to countertops of the type commonly installed in a work area, such as a kitchen, and to devices and methods for enabling installation of fixtures such as sinks and cooking ranges atop such counters.
BACKGROUNDKitchens and other areas requiring a stable flat surface upon which work may be conducted have been known for some time as benefiting from having built-in countertops which line the inner perimeter of the room. In fact, it is believed that all kitchens include at least one countertop upon which foods are cut, prepared, or otherwise processed by people prior to being cooked, eaten, or stored.
Kitchen countertops have over the years been comprised of a wide variety of materials, including without limitation: wood, plastic veneered wood, polymer composites, metals, stainless steel, polymers such as CORIAN® polymer, epoxies, and natural stone. While each countertop material is inherently possessed of its own properties of appearance, durability, hardness, ease-of-cleaning, and longevity, there is a common bond between all countertops that prior to their installation in a given kitchen setting, the individual pieces which shall comprise the finished countertop in its final installed configuration must first be cut to a proper size, which is dictated by the dimensions of the kitchen in which the countertop is to be installed, and by the location(s) in the countertop at which fixtures such as sinks and cooking range tops are to be located.
One popular material from which countertops are fabricated are natural stone materials. These include a wide variety of marble and granite. To prepare natural stone materials to be suitable for use as countertops, the raw stone is first cut into slabs of the appropriate length, width, and thickness dimension. Then, the surface which is to be the work surface is polished to a high luster using techniques known to those skilled in the art, which also may include rounding or beveling of end and/or edge portions. After being cut into an appropriate length to fit a particular installation, the countertop slab is placed into its final position and secured in place using a conventional construction adhesive between the underside of the slab and the frame upon which it rests, which is typically a wooden cabinet. At this stage, the countertop is ready for use by persons desiring to prepare foodstuffs. However, in many installations it is necessary to provide an opening in the countertop itself, to provide for a sink or a cooking range to be located in the countertop. Provision of the opening fur such fixtures is commonly provided at the installation site by the installation personnel, because providing the opening prior to installation of the countertop in its final installed position results in a large section of the slab being removed from a position centrally disposed with respect to its width dimension, which substantially weakens the slab as a whole and would effectively render it non-transportable without a high probability of breakage.
Providing an opening for a sink or a cooking range typically requires that a rectangular hole having a dimension on the order of about 30 inches by 20 inches be cut into the stone slab, which stone slab is commonly about 1 to about 2 inches thick. Thus, the cutting of such a hole provision is not a small or trivial undertaking, and is commonly carried out by a skilled laborer using a hand-held diamond saw. In addition to generating high frequency sound of large amplitude and large volumes of dust, both of which are harmful to the workmen in the area, especially over the course of many installations over the years, the operation inherently includes the possibility that the slab will be broken, marred, defaced, blemished, or otherwise irreparably damaged during the cutting. For cases where the slab is irreparably damaged, the damaged slab must be removed and replaced by a fresh one, which may easily result in a delay taking days or even weeks, not to mention the expense of the new materials and the time required to prepare the slab for installation.
In view of the foregoing difficulties, natural stone countertops are so highly valued by their owners that the cost and tedium associated with their installation has not represented an obstacle. However, if the difficulties associated with the fabrication and installation of natural stone countertops could be overcome, then the method and devices associated with overcoming such obstacles would be well-received by the industry. This would be especially true if it were made possible to install stone countertops without generating large volumes of sonic energy and dust. Further, if a device and method were provided which greatly simplified the operations, the overall cost associated with providing natural stone countertops could be drastically reduced, which would render natural stone countertops within the financial reach of a wider variety of end users. The fulfillment of these and other objects of the present invention shall become apparent to one of ordinary skill in the art after a thorough consideration of what follows in this specification.

Although the adapters of the present invention have been described as being useful in combination with stone slab countertops, they are not limited exclusively to countertops made from such materials but are rather useful with countertops made from all known materials from which countertops may be fabricated, including without limitation, wood, ceramics, metal, composites, resins, etc.
The cutout holes and sink basins which are to be used in conjunction therewith may comprise many different shapes and contours, as such are known in the art including ovals, etc. In addition, the present invention contemplates the use of cutout holes for housing other appliances, and when used in conjunction with a sink basin, the sink basin may or may not include faucet holes. A sink or adapter according to the present invention may be stamped from sheetstock, moulded, cast, machined from steel, polymers, stone etc. In certain embodiments, the sink or adapter will extend from the front edge of the counter to the rear, thus eliminating the need for as much granite, where 2 pieces join on each side, which simultaneously makes installation much easier and less time-intensive.
