The present invention relates to a system and method for mounting a sink, the sink being optionally mounted underneath a surface. In optional embodiments, the surface may include laminates, stone, composite, metals, alloys, concrete or any other type of countertop material that may be utilized.
In the field of home design there are a multitude of different countertops that may be utilized throughout rooms in a residence. One area in which a variety of countertops are often used is in both kitchen and bathroom designs. Often times, especially in the design of a kitchen, countertops are installed and supported by cabinets which may include one or more doors in the area there beneath.
The countertops usually range of from about 20 inches to about 30 inches from the front to the back which is typically adjacent to a wall and often are designed to slightly overhang standard kitchen base cabinets. In certain designs, the countertops may be cut away to allow for the installation of various amenities including stoves, ranges, cook tops and sinks.
Various types of materials have been used for forming countertops used within kitchens or bathrooms. Common materials include natural stones such as granite, lime stone, marble, gabbro and soap stone. Further materials may include wood and metals such as stainless steel and/or copper. Other types may include tile or crafted glass either with or without a base component. Alternatively, countertops may be comprised of synthetic materials such as phenolic resin, epoxy, tile, terrazzo, cast in place materials, acrylic plastic materials such as Corian®, MeganiteTM, avonite and Wilsonart® solid surface, polyester acrylic plastics such as Velstone, engineered stone, laminates such as Formica®, and Arborite as well as concrete.
In some instances users may chose to have a sink installed in a bottom mount or under mount design where the edge of the countertop material is exposed at the opening created for the sink. The sink may then be mounted below the material from below.
U.S. Pat. No. D520,612 discloses, for example, an ornamental design for a sink which may be under mounted to a countertop having hole cut corresponding to such sink design. Otherwise stated, under mount sinks exist below the countertop converse to self rimming sinks which sit within holes in the countertop where the rim of the sink forms a fairly close seal with the top surface of the countertop.
In certain instances, under mount sinks are installed with either an adhesive or a brace to maintain the sink positioned relative to the countertop. The adhesives may include glues, epoxies and other compounds which may affix the sink to the underside of the countertop. Generally, this may include the use of clamps to maintain the sink in the desired position with the drying time of adhesives varying dependent upon the type of adhesive used and the local environmental conditions.
An optional aspect of the present invention is to provide a system for mounting an under mount sink to a countertop within either a kitchen or bathroom or other area where a sink may be desired. Optionally, the system may address one or more disadvantages of the prior art.
Another optional aspect of the invention is to provide a system for mounting a sink to the underside of a countertop that is secure.
Yet another optional aspect of the invention is to provide a system for mounting a sink to the underside of a countertop that is economical to produce, and that is simple and reliable to use.
In accordance with the purpose of the invention, as embodied and broadly described herein, the invention includes a system for mounting a sink in either a kitchen or a bathroom or the like.
An optional embodiment of the system may include one or more flexible supports for supporting the sink beneath the opening cut within the countertop. The flexible support may include adjustment points or no adjustment points, and be of a variety of lengths widths and thicknesses. The system may further include one or more anchors for anchoring the flexible support in supporting the under mounted sink. The anchors may include attachments to the adjacent cabinet walls as well as tightening anchors for adjusting the tension on the flexible supports in removing slack. The tightening anchor may include a tightening element to engage the flexible support. The anchors may include one or more non-tightening anchors or one or more tightening anchors or a combination thereof.
Another optional aspect of the invention includes a system for mounting a sink under a countertop having at least two support rails, each support rail having a top surface, bottom surface and side surfaces which may engage anchors. In such optional aspects, one or more flexible supports may span between the rail brackets.
In yet further optional aspects of the invention the support rails may be formed of wood or alternatively may be formed of woods, plastics, metals or a combination thereof.
In yet further optional aspects of the invention the system for mounting a sink may also include a plurality of holes of various diameters within the support rails. Optionally the system may also include two nuts for use with one or more of the holes of the plurality of holes within the support rails of the system for mounting a sink.
In yet further optional aspects of the present invention the anchors may include one or more support holes sized for the support rails. More specifically, the support holes may optionally have a square shaped opening. Further optionally the anchors may have support holes with optionally an opening with a rounded bottom edge, the opening of which the end of a support rail may fit therewithin.
In yet further optional embodiments the system may include one or more caps having a bolt end indentation and at least one biting edge. Optionally the caps may include a bolt indentation and multiple biting edges with the top surface of the indentation below the top edges of the biting edges and a cap yet to be installed against a sink. Additionally in other optional arrangements of the caps the caps may include extended legs that extend at least partially down on each side of the side surfaces of the rail.
The flexible support may include a plurality of holes with the flexible support positioned between each support rail and beneath the bowls of a multi-bowl sink. In additional optional aspects the flexible support may be of metal, plastic or a combination thereof.
As used herein, the term “engage” means to interact with, interlock with, associate or communicate with.
Further as used herein, the term “tighten” means to compress, fasten, grip, secure, strain, stretch, taughten, tense, bind or constrict.
According to another optional aspect of the invention, a system for mounting a sink may include a combination of flexible supports and anchors. The anchors may include attachments to the adjacent walls, and anchors, including tightening anchors. The system may further include additional flexible supports and anchors for securing the sink. Other styles of anchors include loop anchors, support anchors, corner anchors and any other type of anchor design which may be used in attaching to a cabinet wall. The flexible supports may be configured to prevent movement of the sink from the underside of the countertop.
Thus, where the flexible support and anchors of an optional embodiment of the invention are utilized, the use of adhesive or rigid braces may be precluded. As such a safer sink mounting may result.
Yet another optional aspect of the invention may include a system for mounting a sink where the use of flexible supports and anchors provide securement of a sink underneath a countertop than the use of adhesive alone.
An additional optional aspect of the invention may include a system for mounting a sink where the use of one or more flexible supports, supports and flexible supports provide for less down time than with the use of an adhesive alone which requires some significant time to cure.

The flexible connectors may include a coupler between the flexible supports which may maintain a desired position of the flexible supports in supporting the sink.
An additional optional aspect of the invention may include a mounting system for a sink wherein the countertops include a type of material wherein drilling, screwing or attaching thereto may be undesirable. For example, many of the natural stones including granite, limestone, marble, soapstone, and gabbro require skill to drill into as the user risks cracking or undesirably deforming the countertop surface. Other countertop surfaces include stainless steel, glass as well as many of the synthetic countertop materials in which one would rather not drill a screw or bolt into in installing an undermount sink. Such drilling or screwing may result in cracking or otherwise undesirable changes to the countertop.
Another optional aspect of the invention may include a system wherein the anchors are connected to the cabinet walls or corners and engage supports attachment points for one or more flexible supports so that an under mounted sink is held close to a countertop for use. In yet further optional aspects of the invention a sealant may be utilized at a contact point between the sink and the countertop to as to preclude water from escaping between the contact area of the sink and the countertop.
The mounting system may preclude the reliance upon adhesive in securing an undermounted sink where clamps are typically utilized for extended periods of time in mounting a sink while the adhesive sets. As such, a plumber or other individual may begin work sooner as one optional aspect of the mounting system provides for mounting an undermounted sink both quickly and simply. The mounted sink, for example, may be completely mounted upon the use of the anchors and flexible support.
Yet another optional aspect of the invention may include a mounting system wherein one or more tightening anchors are utilized.
In an optional aspect the tightening anchor may include the use of pins, screws, rings or other mechanical devices to allow for the tightening and securing of the flexible support as described herewithin. Tightening anchors also include anchors in which slack may be removed from the flexible support with or without other mechanical devices which may set the tightening anchor so that further movement is precluded. As such, tightening anchors may include separate pins or other mechanical devices used in conjunction therewith for providing stability with the flexible supports.
The term “providing,” and forms thereof are used in a broad sense and refers to, but are not limited to making available for use, enabling usage, giving, supplying, obtaining, getting a hold of, acquiring, making ready for use, and/or placing in a position ready for use.
The systems that have been described may be particularly useful for mounting a sink for example, in a kitchen or bathroom or other location where the sink is mounted under the countertop.

In optional embodiments, anchors 12 are attached to a cabinet wall with both flexible support couplers and adjuster 76 spanning between the flexible supports and anchors. A user may select the appropriate adjustment point 74 for the desired sink so that proper support is provided to an undermounted sink. Optionally a user may manipulate adjuster 76 to move flexible support coupler 72 further or closer together so as to provide for greater or lesser tension upon a bottom of a sink. The use of the flexible supports together with couplers and at least one adjuster generally provides a system that has a harness-like characteristic in positioning an undermounted sink against the countertop.
Advantageously, a user has multiple sizing options in providing for a system to mount a sink. With multiple adjustments on a flexible support coupler along with an adjuster between flexible support couplers, a user may remove or add anywhere from about two inches to about eighteen inches of length for the system so that desired tension can be provided to an undermounted sink. By changing the slack in the system of the present invention, greater or lesser tension may be applied to a sink in holding the sink against the underside of a countertop. Additionally, the optional embodiment of one or more adjustment points 74 combined with adjuster 76 between flexible support couplers 72 provides for both large and small adjustments in the system so that tension can be readily tailored to the specific sink mounted underneath a countertop. A user can make larger incremental changes in slack in the system by moving the flexible support from one adjustment point to another, which may generally be from about 0.20 inches to about 2 inches apart. Furthermore, by rotating the adjuster, the ends of each flexible support coupler having adjuster hole 78 are drawn nearer together or pushed farther apart.
As illustrated in FIGS. 12-17, an optional embodiment of system 10 my include anchors 12 with support holes 82 which may support support rails 84. Generally, flexible support 14 may span from one support rail 84 to the other support rail 84.
Anchors 12 with support holes 82 may be of a variety of shapes. In some such embodiments, the support holes 82 may have a rectangular shape, though in other embodiments, the support holes 82 may have a circular or oval shape. Support holes 82 are designed with a great enough size so that an end of a support rail 84 may fit there within. In some optional embodiments, support hole 82 may correspond to the cross-section of the end of the support rail 84, though in other optional embodiments, support hole 82 may have an opening that does not correspond to the cross-sectional shape of the end of a support rail 84.

By threading threaded members 88 through support rails 84, the threaded members 88 may extend out of the top surface of support rails 84. This will apply upward pressure on a sink positioned above the threaded members 88 and the support rails 84. In optional embodiments, threaded members 88 may also pass through one or more nuts 90. In optional embodiments, such nuts 90 may include T-nuts.
In year further optional embodiments, caps 92 may be positioned at one end of the threaded end. Generally, caps 92 may include indentation 94 to generally fit to the end of a threaded member 88. Caps 92 may contact the underside of the sink and preclude the twisting ends of threaded members 88 from contacting the underside of a sink. Optionally, caps 92 may have biting edges 98. Biting edges 88 are edges of cap 92 that are bent slightly upward to engage the underside of the sink. This may help preclude cap 92 from rotating with the rotations of its corresponding threaded member 88. Generally, the top surface of the indentation is below the top edges of the biting edges prior to installing the cap. In further optional embodiments one or more of the caps may include extended legs that extend at least partially down on each side surface of the support rail.
In yet further optional embodiments, support rails 84 may engage secondary support 96. Secondary support 96 may be above the top surface of support rail 84 and may be used to elevate a sink up against the underside of the countertop. Threaded members 88 may thread through support rails 84 and engage secondary supports 96. When threaded members 88 are rotated, they may further protrude from the top side of support rails 84 and engage secondary supports 96 and elevate secondary supports 96 relative to support rails 84. Otherwise stated, threaded members 88 may be used to push secondary supports 96 up against the underside of a sink and elevate it up to a countertop. In some optional embodiments, secondary supports 96 may be shorter in length than support rails 84. Also, secondary supports 96 may be formed from similar materials as support rails 84, though in some embodiments may be different. Generally, in optional embodiments, secondary supports 96 may be formed from wood.
In use with support rails 84, flexible support 14 may attach to each support rail 84. In arrangements of the system where the support rails extend from the back wall to the front of the cabinet (i.e. the door side), flexible support 14 attaches to a first support rail 84 on one side of the sink, goes underneath the sink and attaches to the other support rail 84. In optional embodiments, screws or the like may extend through flexible support holes 32 in connecting to connecting holes 86 on support rails 84. In optional embodiments, there may be different sizes of support rail holes 86, corresponding to connecting flexible support 14 or for the threaded members 88.
Generally, in installing an undermounted sink (either single bowl or double bowl) using the embodiment with support rails 84, a user may first optionally measure the width of the sink and calculate the positioning for support rails 84. After doing so, a user may then position anchors 12 in the appropriate position. Anchors 12 may be secured now or later, using any of the methods as described herein. In optional embodiments, a user may slightly pull on anchors 12 to make the portion with support hole 82 extend slightly away from the cabinet wall. A user may then position one support rail 84 between a set of two anchors 12. Generally, two support rails 84 and four anchors 12 may be used. A sink may then be placed upon support rails 84. A user may then rotate threaded members 88 (after optionally ensuring fit), and elevate a sink upward toward the underside of the countertop. In doing so, a user may have the ends of the threaded members 88 in contact with the underside of the sink, or may include caps 92 over the ends of the threaded members so that caps 92 may contact the underside of the sink. In further optional embodiments, secondary supports 96 may be used which contact the underside of a sink. Regardless, threaded members 88 may be rotated until the sink is elevated to the underside of the countertop. After, a user may attach flexible support 14 to one support rail 84, span beneath the sink bowl or bowls and attach flexible support 14 to the opposite support rail 84. Once tightened, the sink should be firmly positioned in place. In such embodiments, caulk or sealant could be utilized for sealing purposes, but one would in no way have to rely on the caulk or sealant for its adhesive properties in maintaining the sink in contact with the countertop.
The system according to the optional aspects of the invention may contain any type of anchor used with a flexible support for providing support to a sink which may be under mounted to a countertop. However, in its broadest aspect, the present invention could also be used to mount a variety of other sinks or at minimum provide support to top mounted sinks or the like.
Furthermore, sizes of various structural parts and materials used to make the above mentioned part or illustrative and exemplary only, and of ordinary skill in the art would recognize that these sizes and materials can be changed as necessary to produce different affects or desired characteristics.
It would become apparent to those skilled in the art that various modifications and variations can be made to the structure and methodology of the present invention. Thus, it should be understood that the invention is not limited to the examples discussed in the specification. Rather, the present invention is intended to cover modifications and variations.
