(45) Components of anchor 12 may be comprised of a variety of materials including metals such as steel, iron, aluminum, alloys, other metals or combinations thereof as well as plastics, polymers and the like in providing suitable anchors for the present invention.
(46) The system that has been described may also be used as described below. The user may first mount anchors 12 to walls 40 prior to placing a flexible support 14 between the anchors. As previously described, one or more anchors may be utilized and any discussion is not intended to limit the invention in any regard. Flexible support 14 may be used and attached between anchors 12 in providing a support for sink 42. Once sink 42 is placed upon flexible supports 14 the countertop may be placed or optionally in embodiments where the countertop is already affixed, the portions of flexible support between the anchors may be sized so as to provide support to push sink 42 against counter 44. This may comprise the use of one or more anchors having tightening element 60 where the user may tighten the flexible support, optionally by manipulating engagement 62 in removing slack from flexible supports 20.
(47) Referring now to
(48) Optional embodiments of the system of the present invention may also include adjuster 76 which may span through adjuster holes 78 within two flexible support couplers 72. Generally adjuster baffles 80 may be included on sides of adjuster holes 78. Baffles 80 as used herein are defined as any sized item which may be utilized to maintain adjuster 76 between two flexible support couplers 72 and can comprise washers, rectangular washers, tabs, threaded items and the like. One or more adjustment holes 78 may be threaded so that baffles 80 may not be required in connecting two flexible support couplers 72 together.
(49) Anchors 12 as disclosed in
(50) Referring now to
(51) 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.
(52) As illustrated in
(53) 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. Depending on the composition of support rail 84, support hole 82 may partially dig into support rail 84. Optionally, a circular support hole 82 may engage a rectangular or polygonal cross-sectional shaped support rail and possibly bite or indent into the corners of support rail 84. Furthermore, anchors 12 may include one or more stabilizing points 93 that may be used to help stabilize the relationship of the anchor 12 with a cabinet wall. Otherwise stated, stabilizing points 93 may partially puncture the top edge of the cabinet wall and help maintain anchor 12 in position either prior to or instead of mounting anchors 12. Additionally, as discussed previously, anchors 12 may also include mounting holes 16.
(54) Support rails 84 may be formed of a variety of materials, ranging from wood, metal, plastic, and combinations thereof, including coated wood and the like. Generally, support rails 84 span just slightly less than the distance between the walls of the cabinet. In many optional embodiments, this is understood to mean the back wall of the cabinet to the front of the cabinet, where a door may be. However in optional embodiments, support rails may span from one sidewall to the opposite sidewall. Furthermore, in instances where a different length may be desired, a user may cut support rails 84 to the proper length.
(55) Support rails 84 may include support rail holes 86 spanning from the topside to the bottom side of each support rail 84. Threaded members 88 may fit within one or more of support rail holes 86. In optional embodiments, threaded members 88 may include screws or bolts. Threaded members 88 may be used to elevate a sink to the countertop. Generally speaking, once support rails 84 are in place, a user can place an undermounted sink above the support rails 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.
(56) In yet 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.
(57) 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.
(58) 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.
(59) 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.
(60) 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.
(61) Furthermore, sizes of various structural parts and materials used to make the above mentioned parts are illustrative and exemplary only, and one of ordinary skill in the art would recognize that these sizes and materials can be changed as necessary to produce different effects or desired characteristics.
(62) 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.
