FAUCET MOUNTING ANCHOR

BACKGROUND AND SUMMARY

The present disclosure relates generally to faucets and, more particularly, to a mounting system for a faucet.

The installation of a faucet onto a mounting deck is often a difficult and time-consuming task. At least some of the installation may require the installer to work in the cramped and dimly lit work area under the sink or mounting deck. More particularly, faucets are typically attached to the mounting deck with threaded connections which must be made under and behind the sink basin wherein there is very little room to work.

As such, there is a need to provide a less cumbersome and complicated system of installing faucets or interchanging different faucet styles onto a mounting deck which can be done largely from the top of the countertop or sink.

According to an illustrative embodiment of the present disclosure, a faucet assembly may include an anchor including a mounting body extending between opposing upper and lower ends. The upper end of the mounting body may include a retaining lip, a faucet support positioned above the anchor, an adapter positioned within the faucet support, and a mounting tube positioned within the faucet support and operably coupled to the adapter, the mounting tube comprising at least one finger arranged about an opening having a diameter, the at least one finger releasably engaging the lip of the anchor if the diameter is reduced, wherein rotation of the adapter draws the mounting tube within the mounting body, moving the one or more fingers inward and reducing the diameter such that the at least one finger releasably engages the lip of the anchor thereby coupling the faucet support to the anchor.

According to another illustrative embodiment of the present disclosure, a faucet assembly may include a first anchor, including a body extending between opposing upper and lower ends, the first anchor including external threads disposed on the upper end of the body. The faucet assembly may also include a housing receiving a mixing valve, the housing including internal threads to engage with the external threads of the first anchor. The faucet assembly may also include a second anchor including a body having at least one recess. The faucet assembly may also include a spout assembly comprising a substantially hollow spout with opposing first and second openings, a connector tube releasably attached to the spout at the first opening of the spout, the connector tube including a groove, and a bearing releasably attached to the tube, the bearing including first fingers to engage with the groove of the connector tube and second fingers to engage with the one or more voids in the second anchor, wherein rotation of the spout rotates the mounting tube relative to the first fingers of the bearing, and the bearing remains fixed relative to the second anchor.

Additional features and advantages of the present disclosure will become apparent to those skilled in the art upon consideration of the following detailed description of the illustrative embodiment exemplifying the best mode of carrying out the disclosure as presently perceived.

DETAILED DESCRIPTION OF THE DRAWINGS

The embodiments of the disclosure described herein are not intended to be exhaustive or to limit the disclosure to precise forms disclosed. Rather, the embodiment selected for description have been chosen to enable one skilled in the art to practice the disclosure.

Referring initially to FIGS. 1-10, and with particular reference to FIG. 9, a faucet assembly 101 is shown. An anchor 115 is mounted to a mounting deck 111. The mounting tube 207 is positioned within a faucet assembly 101 or faucet support, including the delivery spout 107, and the adapter 201 and the clutch 211 are installed in the mounting tube 207 inside the delivery spout 107. The sleeve 209 may optionally be installed in the mounting tube 207, and guides conduits through the mounting tube 207 and the anchor 115. In operation, the delivery spout 107 with the mounting tube 207 including the adapter 201 and the clutch 211 are positioned over the anchor 115, so that the fingers 403 of the mounting tube 207 are adjacent to the lip 405 of the anchor 115. The adapter 201 is rotated, drawing the mounting tube 207 into the delivery spout 107 and reducing the diameter of opening in the mounting tube containing the fingers 403. The fingers 403 engage with the lip 405 of the anchor 115, forcing the delivery spout 107 towards the mounting deck 111, so that the delivery spout 107 is in releasable communication with the anchor 115. The neck adapter 203 includes fingers that engage with the adapter 201 and the neck 105, so that rotation of the neck 105 does not rotate the adapter 201 (i.e., the neck 105 may freely rotate without rotating the other components of the faucet assembly 101).

The illustrative embodiment of a faucet assembly 101 is shown as including an upper faucet assembly 102 positioned above an anchor assembly 113. The upper faucet assembly 102 illustratively includes a body housing or delivery spout 107 including a mixing valve 407 coupled to a handle 109, and a neck 105 in communication with a pull-out spray head 103 (i.e., detachable from the neck 105 of the delivery spout 107). The mixing valve 407 is fluidly coupled to a waterway assembly 119a, 119b, and 121, which provides fluid communication to hot and cold water supplies (not shown). The waterway assembly 119a, 119b, and 121 also illustratively provides fluid communication between an outlet of the mixing valve 407 and the pull out spray head 103. An anchor 115 is secured to a lower portion of the delivery spout 107. The anchor assembly 113 includes an anchor body 115 which receives fasteners 403 to couple the anchor 115 to the delivery spout 107, shown in FIG. 4. The anchor 115 also includes cleats 117a and 117b to secure the anchor 115 to the lower surface 127 of the mounting deck 111. Described more fully below, the cleats 117a and 117b ride longitudinally in a track 133 disposed in the anchor 115. Inlet conduits (119a shown in FIG. 1, 119b shown, for example, in FIGS. 1 and 4) may supply, for example, water from hot and cold water sources (not shown) to the mixing valve 407. The mixing valve 407 may adjust the flow from the inlet conduits 119a and 119b, and the mixed sources may flow into an outlet conduit 121 fluidly coupled to the spray head 103.

With further reference to FIG. 1, a handle 109 is coupled to a stem 409 of the mixing valve 407 in a conventional manner, for example, through the use of a set screw (not shown). The mixing valve 407 controls the rate and relative proportion of water flowing from cold and hot water inlet conduits 119a and 119b, of the waterway assembly 20 to outlet conduit 121. The mixing valve 18 may be of conventional design, and illustratively of the type disclosed in U.S. patent application Ser. No. 11/494,889, filed Jul. 28, 2006, entitled “MIXING VALVE,” incorporated by reference herein. Similarly, the waterway assembly may be of conventional design, and illustratively of the type disclosed in U.S. patent application Ser. No. 11/700,634, filed Jan. 31, 2007, entitled “FAUCET INCLUDING A MOLDED WATERWAY ASSEMBLY,” incorporated by reference herein.

Each of the inlet conduits 119a and 119b illustratively includes an end connector (not shown) configured to couple to a fluid coupling for supplying water from hot and cold water sources (not shown). The fluid couplings may comprise a quick release coupling, such as PMC Series couplings available from Colder Products Company of St. Paul, Minn. Other conventional fluid couplings may be substituted therefor, such as those detailed in U.S. Pat. No. 6,672,628.

Illustratively, the inlet conduits 119a and 119b are formed of a flexible tubular material to facilitate positioning of the respective end connectors (not shown) relative to the faucet assembly 101. In one illustrative embodiment, the inlet conduits 119a and 119b and outlet conduit 121 are all formed of cross-linked polyethylene (PEX).

With reference to FIGS. 2 and 3, the anchor 115 is supported by a mounting deck 111, typically a countertop or sink deck having one or more access openings. As detailed herein, a coupler or guide releasably couples the upper faucet assembly 102 to the anchor 115.

With reference to FIGS. 7, 8, and 10, the anchor 115 illustratively includes an anchor floor portion 219 which is mounted from the top of the mounting deck 111 and rests on the upper surface 129 thereof. It should be noted that the anchor 115 may also be mounted from the underside of the mounting deck 111 below its lower surface. The anchor 115 may include a void 707 to receive the waterway assembly 615, or the inlet conduits 119a and 119b and the outlet conduit 121. The anchor may also comprise one or more projections 613 or other structures for receiving the mounting tube 207 in limited orientations. For example, the projections 613 may receive structures on the mounting tube 207, such as voids 611, to allow the mounting tube 207 to be installed on the anchor 115 in only one orientation.

First and second attachment posts 217a and 217b extend downwardly from the anchor 115. The attachment posts 217a and 217b each include a plurality of external threads and are configured to operably couple with the cleats 117a and 117b. An upper end of each post 217a and 217b extends through the anchor 115 and includes a head configured to be manipulated by a tool, such as a screwdriver or Allen wrench (not shown). Upper and lower apertures 711 and 709 receive each attachment post 217a and 217b, respectively. The upper apertures 711 and the lower apertures 709 are formed within the anchor 115. Further, the anchor includes grooves 133 (shown for attachment post 217a, not shown for attachment post 217b) for each of the attachment posts 217a and 217b. Grooves 133 are configured to receive the respective attachment post 217a and 217b and guide the respective cleats 117a and 117b in movement longitudinally therealong. In one illustrative embodiment, the anchor 115 is formed, for example, through molding of a thermoplastic material.

The mounting plate cleats 117a and 117b each include a threaded opening configured to threadably engage the respective attachment post 217a and 217b. Each cleat 117a and 117b is substantially wedge shaped and includes an upper surface 703 configured to cooperate with the anchor floor portion 219 to clamp the anchor 115 to the mounting deck 111. When the anchor 115 is positioned on the mounting deck 111, the threaded attachment posts 217a and 217b are rotated to cause the mounting plate cleats 117a and 117b to move longitudinally up and down on the posts 217a and 217b, respectively. Illustratively, counterclockwise rotation of attachment posts 217a and 217b causes cleats 117a and 117b to move downwardly or away from mounting deck 111 to an unlocked position. The cleats 117a and 117b may be directed inside of the anchor 115, in a respective support structure (shown as 705 for cleat 117a, not shown for cleat 117b). The support structures 705 allow the cleats 117a and 117b to enter the anchor 115 during installation, so that the cleats 117a and 117b do not interfere with the walls of the void created in the mounting deck 111 to install the anchor 115. The shape of the support structures 705 conform to the cross-sectional shape of cleats 117a and 117b

Clockwise rotation of attachment posts 217a and 217b causes cleats 117a and 117b to move upwardly or toward mounting deck 111 to a locked position. In the locked position, the upper surfaces 703 of the cleats 117a and 117b abuts the bottom or lower surface 127 of mounting deck 111, securing the anchor 115 thereto.

The cleats 117a and 117b are prevented from rotating with the attachment posts 217a and 217b as they are turned, by guide surfaces 711 of each cleat 117a and 117b. The guide surfaces 711 abut against cooperating stop surfaces 713 of the grooves 133, upon rotation of the cleats 117a and 117b, respectively. This causes cleats 117a and 117b to ride up or down the attachment posts 217a and 217b within the grooves 133 as they are rotated instead of rotating 360 degrees with the rotation of the posts 217a and 217b. As noted above, attachment posts 217a and 217b are stabilized and secured at their bottom portions by the anchor 115 body.

The mounting tube 207 (shown particularly in FIGS. 6, 8, 9, and 10) may be formed from a thermoplastic material. The mounting tube 207 is a hollow cylindrical shape and includes a hollow inner portion and an outer portion. The top of the mounting tube 207 may include internal threads 223 disposed on the surface of the inner portion, and the threads 223 of the mounting tube 207 may engage similarly sized external threads 205 on the adapter 201. The diameter of the mounting tube 207 may increase from the top of the mounting tube 207 to the bottom of the mounting tube 207, to conform to the inner shape of the spout 107, and the bottom of the mounting tube 207 may include one or more resilient fingers 403 to secure the mounting tube 207 to the anchor 115. The fingers 403, shown particularly in FIGS. 4, 4A, 6, 8, and 9, may extend outwardly from the longitudinal axis of the mounting tube 207, although may flex inwardly, toward the longitudinal axis of the mounting tube 207, if force is applied to the fingers 403, that is, the fingers 403 may be inwardly biased. The fingers 403 may include a flat surface to engage with the anchor lip 405.

In certain illustrative embodiments, the fingers 403 are biased radially inwardly. The fingers 403 may include one or more projections having an engagement surface 413, shown particularly in FIGS. 4 and 4A, and the engagement surface 413 may releasably engage with the bottom surface of the anchor lip 405. Shown in greater detail below, the diameter of the bottom portion of the mounting tube 207 with the fingers 403 may be larger than the diameter of the anchor body 115, so that the mounting tube 207 may be positioned over the anchor body 115. If force is applied to the outer surface of the mounting tube 207, such as by the delivery spout 107 during installation, the fingers 403 may flex inwardly toward the center of the mounting tube 207. The engagement surface 413 of the fingers 403 may engage the bottom surface of the anchor lip 405, preventing the mounting tube 207 from being removed from the anchor 115 body, shown in FIG. 4A.

The delivery spout 107 (shown in FIGS. 1-4) may be a metal or a plastic material, and may enclose the components of the upper faucet assembly 102, e.g., the outlet tube may be slidably received within the delivery spout 107. The delivery spout 107 may include an opening for the mounting tube 207, an opening for the adapter 201, and an opening for the neck 105. The mixing valve 407 may be disposed within the delivery spout 107, and the mixing valve 407 may be releasably engaged to the delivery spout 107 with a decorative cap 131 or bonnet nut. The decorative cap 131 may include threads that may engage with threads on the mounting body, releasably engaging the delivery spout 107 to the decorative cap 131 and retaining the mixing valve 407 within the delivery spout 107.

The sleeve 209 may be a plastic material, and may by cylindrical and have a hollow inner surface and an outer surface. The center portion of the sleeve 209 may guide the pull-out hose 225 through the mounting tube 207 and through the anchor 115, and the outer surfaces of the sleeve 209, particularly the wings 501 (shown particularly in FIGS. 7, 8, and 10) may guide the inlet conduits 119a and 119b and the outlet conduit 121 through the mounting tube 207 and through the anchor 115 to the lower surface 127 of the mounting deck 111. Shown in FIG. 5, the wings 501 of the sleeve 209 may position the inlet conduits 119a and 119b and the outlet conduit 121 so that the inlet conduits 119a and 119b and the outlet conduit 121 do not tangle or deviate from predefined indentations within the anchor body 115, and ensures that the inlets and the return are separated from the hose 225 positioned within the sleeve 209. The hose 225 within the sleeve 209 may extend and retract as the spray head 103 is uncoupled and removed from the neck 105, and replaced and coupled within the neck 105 during operation. If the hose 225 and the inlet conduits 119a and 119b and the outlet conduit 121 were not separated, the motion of the hose 225 may scrape and/or wear the inlet conduits 119a and 119b and the outlet conduit 121. Shown in FIGS. 4 and 6, the sleeve 209 also includes one or more projections 213 at the top of the sleeve 209. The one or more projections 213 releasably engage with one or more voids 603 in the mounting tube 207, so that the sleeve 209 is inserted within the mounting tube 207, and the one or more projections 213 engage with the voids 603 of the mounting tube 207, releasably seating the sleeve 209 within the mounting tube 207.

The waterway assembly 615 includes the inlet conduits 119a and 119b and the return conduit 121, as well as a coupling element 601 that fluidly couples the inlet conduits 119a and 119b and the outlet conduit 121 to the mixing valve 407. The inlet conduits 119a and 119b may each be a hollow tube for carrying liquid from a water source (not shown) to the mixing valve 407. The outlet conduit 121 may be a hollow tube, and may carry liquid from the mixing valve 407 to the spray head 103. The coupling element 601 may form one end of each of the inlet conduits 119a and 119b and the outlet conduit 121. The coupling element 601 may include a deformable gasket formed from an elastomeric material to seal the inlet conduits 119a and 119b and the outlet conduit 121 to the mixing valve and separate the inlet conduits 119a and 119b and the outlet conduit 121 from mixing before reaching the mixing valve 407.

The adapter 201 may be metal or plastic. The adapter 201 may be cylindrical and may include external threads 205 on a lower portion that may threadably engage the internal threads 223 of the mounting tube 207. The adapter 201 may also include one or more projections 301, shown in FIGS. 3 and 8, that engage with the clutch 211, or one or more surfaces 901 that engage with complimentary surfaces 903 on the clutch 211, so that rotation of the adapter 201 may rotate the clutch 211 when the adapter 201 is installed in the clutch 211. The adapter 201 may also include one or more projections 605 that may allow projections 605 on the clutch 211 to releasably engage the adapter 201, holding the adapter 201 in place after installation of the adapter 201. The adapter 201 may include one or more features that may engage projections on the neck adapter 203.

Shown in FIGS. 3, 6, and 8, the clutch 211 may be plastic or another material. The clutch 211 may include clutch fingers 605 and clutch projections 607 on the outer surface of the clutch 211 and one or more projections on the inner surface of the clutch. Installed within the delivery spout 107, the clutch fingers 605 may abut a lip 303 or other projection on the inner surface of the delivery spout 107, and may releasably attach the clutch 211 to the delivery spout 107. The inner surface of the delivery spout 107 may be formed such that the clutch projections 607 selectively engage and release the inner surface of the delivery spout 107 when the clutch 211 is rotated within the delivery spout 107. For example, and without limitation, the inner surface of the delivery spout 107 may be hexagonal in shape. The clutch projections 607 may be shaped so that the clutch projections 607 rest in the area formed by the angles of the hexagonal delivery spout 107 inner surface, and resist clockwise or counterclockwise movement. The clutch projections 607 may deform when the clutch 211 is rotated within the delivery spout 107, and may return to an original shape when resting in the area formed by the angles of the hexagonal delivery spout 107 inner surface. The clutch 211 may be rotated within the delivery spout 107, but the clutch 211 may be biased to rest so that the clutch projections 607 rest within the areas formed by the angles of the hexagonal delivery spout 107 inner surface.

The neck adapter 203 may be a plastic material, and may include one or more projections 905 on the outer surface that releasably engage with one or more projections 415 on the inner surface of the neck 105 so that the neck 105 is releasably engaged with the neck adapter 203. The neck adapter 203 may also include one or more projections 305 on the inner surface of the neck adapter 203 that rotatably engage with one or more surfaces 907 of the adapter 201 to allow the neck adapter 203 to rotate freely around the adapter 201, such that rotation of the neck adapter 203 does not rotate the adapter 201 or the clutch 211. When the neck 105 is installed on the neck adapter 203, the neck 105 is in communication with the neck adapter 203, so that rotation of the neck 105 rotates the neck adapter 203. Rotation of the neck adapter 203, however, does not rotate the adapter 201, as the projections 305 of the neck adapter ride in the surfaces 907 of the adapter 201.

The neck 105 may be a metal or plastic material, and may be similar to the material of the delivery spout 107. The neck 105 may be substantially hollow, and may allow the tube to pass through the neck 105.

The spray head 103 may be of a conventional type, and may include a shell or housing formed of a metal or plastic material. The material may be similar to the material of the delivery spout 107 and the neck 105. The spray head 103 may include inserts, such as an aerator and/or nozzles, to provide stream and spray modes for liquid delivery.

Shown in FIG. 8, to mount the anchor 115 onto the mounting deck 111, the mounting adapter is positioned over the opening of the mounting deck 111. In one embodiment, the mounting adapter is not used, and the anchor 115 is mounted directly to the mounting deck 111. To mount the anchor 115, the cleats 117a and 117b are oriented in retracted positions and are nested within respective supports, and the anchor 115 body is passed through the opening of the mounting adapter and the mounting deck 111 from above. The attachment posts 217a and 217b are rotated clockwise such that the cleats 117a and 117b rotate out of the anchor 115 to extended positions outside of respective supports. Continued clockwise rotation causes the cleats 117a and 117b to move upwardly along the length of the respective post 217a and 217b such that the upper surfaces 703 of the cleats 117a and 117b engage the lower surface 127 of the mounting deck 111, and the anchor floor portion 219 engages the mounting adapter, thereby clamping the mounting adapter and the mounting deck 111 between the upper surfaces of the cleats 117a and 117b and the anchor 115 floor portion 219.

With respect to FIG. 9, the clutch 211 is attached to the delivery spout 107 by pushing the clutch 211 through the top of the delivery spout 107 until the clutch fingers 605 engage with the inner surface of the delivery spout 107. The adapter 201 may be inserted through the opening in the clutch 211, such that the threads 205 of the adapter 201 may extend into the delivery spout 107. Projections on the inner surface of the clutch may releasably engage with the threads 205 of the adapter 201, preventing the adapter 201 from being removed from the delivery spout 107. The adapter 201 and/or the threads 205 of the adapter 201 may be formed so that the rotation of the adapter 201 may rotate the clutch 211. In one embodiment, surfaces 903 inside of the clutch 211 may engage with complimentary surfaces 901 of the adapter 201 in a way that the rotation of the adapter 201 may rotate the clutch 211. The neck adapter 203 may be positioned over the adapter 201, and one or more projections 305 of the neck adapter 203 may releasably engage one or more indentations 907 of the adapter 201. The neck adapter 203 may freely rotate about the adapter 201, so that rotation of the neck adapter 203 does not rotate the clutch 211.

Shown with respect to FIG. 10, the sleeve 209 may be installed within the mounting tube 207. The projections 213 of the sleeve 209 may releasably engage with the voids 603 of the mounting tube 207. The rear wing 701 of the sleeve 209 may abut the inner surface of the mounting tube 207, positioning the sleeve 209 within the mounting tube 207.

The mounting tube 207 may then be positioned within the delivery spout 107. The mounting tube 207 may be positioned so that the mounting tube 207 hose void 609 may be positioned next to the waterway inlet 411 of the delivery spout 107. The inlet conduits 119a and 119b and the outlet conduit 121 may be inserted through the waterway inlet 411 of the delivery spout 107, and may continue through the mounting tube 207 hose void 609 and into the mounting tube 207. The wings 501 of the sleeve 209 may align the inlet conduits 119a and 119b and the outlet conduit 121 within the mounting tube 207, and may prevent the inlets and the return from twisting. The threads 205 of the adapter 201 may engage the threads 223 of the mounting tube 207 within the delivery spout 107. The mounting tube 207 may be prevented from rotating 360 degrees within the delivery spout 107 by the inlet conduits 119a and 119b and the outlet conduit 121 extending through the delivery spout 107 and into the mounting tube 207 through the mounting tube 207 hose void 609. The adapter 201 may be rotated, and the threads 205 of the adapter 201 may engage with the threads 223 of the mounting tube 207. As the mounting tube 207 is constrained from rotating 360 degrees, the mounting tube 207 is drawn into or out of the delivery spout 107 on a longitudinal axis when the adapter 201 is rotated. The mounting tube 207 may be drawn into the delivery spout 107 so that the fingers 403 of the mounting tube 207 may extend from the bottom of the delivery spout 107.

Next, shown with respect to FIGS. 6, 8, and 10, the delivery spout 107, clutch 211, neck adapter 203, adapter 201, mounting tube 207, and inlet conduits 119a and 119b and outlet conduit 121 are positioned above the anchor 115. The inlet conduits 119a and 119b and the outlet conduit 121 are positioned so that the inlets and the return extend out of the bottom of the delivery spout 107, to the upper surface 129 of the mounting deck 111, through the mounting adapter, through the anchor 115, and to the lower surface 127 of the mounting deck 111. The opening of the mounting tube 207 is sized to be larger than the upper portion of the anchor 115. The projections 613 of the anchor 115 may be positioned within the voids 611 located in the mounting tube 207, so that the mounting tube 207 may be positioned over the anchor 115 in one orientation. The fingers 403 of the mounting tube 207 may be positioned to abut the anchor 115 floor portion 219, and may rest on the anchor 115 floor portion 219.

The adapter 201 may be rotated, so that the threads 205 of the adapter 201 engage the threads 223 of the mounting tube 207. The neck adapter 203 may be positioned around the portion of the adapter 201 extending out of the delivery spout 107, so that the rotation of the adapter 201 may include the use of a tool able to releasably engage with one or more structures on the adapter 201. In one embodiment, one or more voids in the adapter 201 may engage with one or more projections of a tool, to enable the tool to rotate the adapter 201. The engagement of the threads 205 of the adapter 201 and the threads 223 of the mounting tube 207 may move the mounting tube 207 into the delivery spout 107. The opening of the delivery spout 107 may be narrower than the opening of the mounting tube 207, so that when the mounting tube 207 is drawn into the delivery spout 107, the fingers 403 of the mounting tube 207 may be pressed together by the narrower delivery spout 107. The fingers 403 may close together, so that the diameter of the mounting tube 207 opening may become smaller. The fingers 403 may engage with the lip 405 of the anchor 115 as the diameter of the mounting tube 207 becomes smaller. The adapter 201 may continue to be rotated until the body indentation 221 abuts the anchor floor 219, as shown in FIGS. 2 and 3. The fingers 403 engaged with the lip 405 of the anchor 115 may prevent the delivery spout 107 from being removed from the anchor 115. When the body indentation 221 abuts the anchor floor 219, the adapter 201 may not be able to be rotated further, which may prevent overtightening. When the body indentation 221 abuts the anchor floor 219, the delivery spout 107 may substantially abut the upper surface of the mounting adapter or the upper surface of the mounting deck 111. When the body indentation 221 abuts the anchor floor 405, the tool may be removed.

If the delivery spout 107 is to be removed from the anchor 115, for example for refitting or deinstallation, the adapter 201 may be rotated in the opposite direction as the adapter 201 was rotated to install the delivery spout 107 to the anchor 115. The threads 205 of the adapter 201 may engage with the threads 223 of the mounting tube 207, and may move the mounting tube 207 away from the adapter 201, and out of the delivery spout 107. Moving the mounting tube 207 away from the adapter 201 may cause the fingers 403 to expand away from one another as they become disengaged from the lip 405 of the anchor 115. The diameter of the opening of the mounting tube 207 may increase, and the diameter increase may allow the fingers 403 to become disengaged from the lip 405 of the anchor 115. The mounting tube 207 and delivery spout 107 may be removed from the anchor 115 when the fingers 403 are disengaged from the lip 405 of the anchor 115.

The anchor 115 may also be removed from the mounting deck 111. To remove the anchor 115, the attachment posts 217a and 217b are rotated counterclockwise, so that the cleats 117a and 117b move downwardly along the length of the posts 217a and 217b, disengaging the cleats 117a and 117b from the lower surface of the mounting deck 111. The posts may continue to be rotated counterclockwise, and the cleats 117a and 117b may continue to move downwardly along the length of the posts until the cleats 117a and 117b reach their respective supports 705, and rotate into the anchor 115 within the supports 705. The anchor 115 may then be lifted out of the hole in the mounting deck 111. The mounting adapter may be removed from the mounting deck 111 as well.

In an alternate embodiment, shown in FIGS. 11-21, a further illustrative spout including a delivery spout and a handle are shown mounted to mounting deck 111. With respect to FIG. 11, the valve structure 1103 is mounted to the mounting deck 111. Inlet conduits 119a and 119b carry fluid from below the mounting deck 111, through the valve anchor structure 1113, and to a valve, where the fluids are mixed in a proportion selected by the valve, and the combined fluids are passed in an outlet conduit through the valve anchor structure 1113 and below the mounting deck 111. The spout structure 1101 is mounted to the mounting deck 111 beside the valve structure 1103 with a spout anchor structure 1115, which allows the return conduit to pass through the spout anchor structure 1115 and into the spout structure 1101.

The spout structure 1101 and the valve structure 1103 are mounted to the mounting deck 111 with a spout anchor structure 1115 and a valve anchor structure 1113, respectively. The spout structure 1101 and the valve structure 1103 are shown together mounted to a mounting deck in FIG. 11.

With respect to the valve structure 1103, shown in FIGS. 11-16, the anchor structure 1113 for the handle may be similar to the anchor 113 previously shown, however instead of an anchor lip 405 securing the mounting tube 207, the valve anchor 1113 may provide external threads 1223 to releasably secure the housing 1109 to the valve anchor 1113. The valve anchor cleats 117a and 117b may releasably engage the bottom surface 127 of the mounting deck 111, and, in an embodiment, may include a ring 1211 separating the bottom surface of the anchor 1113 with the top surface 1215 of the mounting deck 111, so that the ring 1211 is engaged with the top surface 1215 of the mounting deck 111 and the surface of the anchor 1113. The anchor threads 1223 may be used to releasably secure the housing 1109 to the valve anchor 1113, and thus the valve structure 1103 to the valve anchor 1113, as more fully explained below.

The ring 1211 may be a metal or plastic ring, and has an internal void so that the ring 1211 surrounds the valve anchor 1113, and is located adjacent to the upper surface 1215 of the mounting deck. In the embodiment shown in FIG. 13, the ring 1211 includes ring snap fingers 1303 that extend through the valve anchor 1113 at anchor openings 1303, and releasably engage with the valve anchor 1113 to secure the ring 1211 to the valve anchor 1113. The ring 1211 may include a lip 1305 that may interface with a complimentary lip 1307 on the housing 1109 to prevent the valve anchor 1113 from being seen from outside of the housing 1109 when the housing 1109 is installed on the valve anchor 1113.

Inlet conduits 119a and 119b shown in FIGS. 15 and 16 may supply, for example, water from hot and cold water sources (not shown) to the mixing valve 1207. The mixing valve 1207 may adjust the flow from the inlet conduits 119a and 119b based on the position of the stem 1205, and the mixed sources may flow into the outlet conduit 121.

The mixing valve 1207, in the embodiment, is in communication with a keying ring 1227 that surrounds the mixing valve 1207. In the embodiment, the keying ring 1227 is fixed with respect to the mixing valve 1207. The keying ring 1227 has an internal void to allow the inlet conduits 119a and 119b and the outlet conduit 121 to pass through, and includes one or more projections or indentations that interact with complimentary projections or indentations on the valve anchor 1113, so that the projections or indentations on the keying ring 1227 and on the valve anchor 1113 fit together in only one orientation. That is, the keying ring 1227 and the mixing valve 1207 that the keying ring 1227 is fixed to must be rotated until the projections or indentations of the keying ring 1227 match with the complimentary projections or indentations of the valve anchor 1113, allowing the mixing valve 1207 to fit into the valve anchor 1113 in one orientation.

The housing 1109 may be a metal or a plastic, and may be in the shape of a cylinder. The first opening 1235 includes threads 1221 disposed on the inner surface of the housing 1109, which are adapted to engage threads 1223 located on the valve anchor 1113. The surface of the housing 1109 near the second opening 1229 curves inward at 1231, so that the second opening 1229 is a smaller diameter than the first opening 1235. The narrowing diameter of the housing 1109 from the first opening 1235 to the second opening 1229 forms a portion of the inner surface 1231 that retains the mixing valve 1207 during installation, preventing the mixing valve 1207 from being removed from the second opening 1229. In an embodiment, the outer surface of the second opening 1229 contains projections or indentations that may engage a tool with complimentary projections or indentations, so that the tool may releasably grip the outer surface and allow the tool to rotate the housing 1109. The stem 1205 of the mixing valve 1207 extends through the second opening 1229.

During installation of the handle assembly 1103, the mixing valve 1207 and the keying ring 1227 are positioned within the housing 1109 so that the stem 1205 of the mixing valve 1207 extends out of the second opening 1229 of the housing 1109. The mixing valve 1207 may be inserted into the housing 1109 through the first opening 1235, as the second opening 1229 is dimensioned to be too narrow for the mixing valve 1207 to pass through.

The ring 1211 is pressed onto the bottom surface of the valve anchor 1113, so that the ring snap fingers 1303 flex outwardly and pass through the anchor openings 1301. When the projections on the ring snap fingers 1303 reach the inner surface of the valve anchor 1113 through the anchor openings 1301, the ring snap fingers 1303 flex inwardly so that the projections abut the inner surface of the valve anchor 1113, releasably fixing the ring 1211 to the valve anchor 1113.

To mount the valve anchor 1113 onto the mounting deck 111, the cleats 117a and 117b are oriented in retracted positions and are nested within respective supports, and the anchor 1113 is passed through the mounting deck 111 from above. The ring bottom surface 1219 is sized so that it is wider than the opening through the mounting deck 111, or additional material is used to fill in the opening through the mounting deck so that the ring bottom surface 1219 contacts the upper surface 1215 of the mounting deck 111. The attachment posts 217a and 217b are rotated clockwise such that the cleats 117a and 117b rotate out of the anchor 115 to extended positions outside of respective supports. Continued clockwise rotation causes the cleats 117a and 117b to move upwardly along the length of the respective post 217a and 217b such that the upper surfaces 703 of the cleats 117a and 117b engage the lower surface 127 of the mounting deck 111, and the anchor floor portion 219 engages the mounting adapter, thereby clamping the mounting adapter and the mounting deck 111 between the upper surfaces of the cleats 117a and 117b and the anchor 115 floor portion 219.

The inlet conduits 119a and 119b, shown in FIGS. 15 and 16, and the outlet conduit 121 are positioned to extend through the void in the anchor 1113 from the top surface 1215 of the mounting deck 111 to the bottom surface 127 of the mounting deck 111. The mixing valve 1207 and the housing 1109 are positioned so that the projections or indentations of the keying ring 1227 match with the projections or indentations of the anchor 1113, indicating a correct positioning of the keying ring 1227 and the mixing valve 1207. The inner threads 1221 of the housing 1109 contact the outer threads 1223 of the anchor 1113, and the housing 1109 is rotated so that the inner threads 1221 of the housing 1109 and the outer threads 1223 of the anchor 1113 are in communication with one another. The housing 1109 may be tightened by a tool (not shown). When tightened, the lip 1307 of the housing 1109 is positioned over the lip 1305 of the anchor 1113, obstructing the view of the anchor 1113 from the outside of the valve structure 1103. The handle 1107 is attached to the stem 1205 and held in place with a set screw 1203. A user may operate the handle 1107 to manipulate the stem 1205 and the mixing valve 1207 to change flow and the mixture of liquid from the inlet conduits 119a and 119b to the outlet conduit 121.

The spout structure 1101, shown in FIGS. 11 and 17-21, may also be mounted to the mounting deck. The spout structure 1101 is mounted to the deck with a spout anchor structure 1115, described below.

The anchor structure 1115 for the spout 1105 may be similar to the anchor structure 113 previously shown, however instead of an anchor lip 405 securing the mounting tube 207, the spout anchor 1115 may contain one or more windows 1715 to provide a releasable attachment for one or more fingers 1713 of a bearing 1711 in communication with the spout structure 1101. The spout anchor cleats 117a and 117b may releasably engage the bottom surface 127 of the mounting deck 111, and, in an embodiment, may include an insulator ring 1701 separating the top surface of the anchor 1103 from the top surface 1215 of the mounting deck 111, so that the ring 1701 is engaged with the top surface 1215 of the mounting deck 111 and the anchor 1103.

The ring 1701 is illustratively formed of a non-conductive material (e.g., electrically non-conductive plastic), and has an internal void so that the ring 1701 surrounds the anchor 1115, and is located adjacent to the upper surface 1215 of the mounting deck 111. In an embodiment, the ring 1701 includes ring snap fingers (not shown) that extend through the anchor 1115 at anchor openings (not shown), and releasably engage with the anchor 1115 to secure the ring 1701 to the anchor 1115. The ring 1701 may include a lip 1725 that may interface with the first opening of the spout 1105 to prevent the anchor 1115 from being seen from outside of the spout 1105 when the spout 1105 is installed on the anchor 1115. The ring 1701 may also include a groove 1729 into which may be disposed an elastomeric or foam gasket 1730. The elastomeric or foam gasket 1730 may extend below the lower surface of the ring 1701, so that it may be in contact with the upper surface 1215 of the mounting deck 111. The elastomeric or foam gasket 1730 may deform during installation to create a seal between the ring 1701 and the upper surface 1215 of the mounting deck 111. In an embodiment, the elastomeric or foam gasket 1730 may be formed in a different shape, and may include one or more projections interacting with the groove 1729 to hold the member in place when positioned on the ring 1701.

A set ring 1721 may be received within with the spout 1105, and may, in an embodiment, be fixed in the spout 1105 by brazing or other permanent mounting. The set ring 1721 may be fixed in relation to the spout 1105 so that when the spout 1105 rotates, the set ring 1721 also rotates. The set ring 1721 may be cylindrical and may have an internal void. The set ring 1721 contains a portion 1735 that interferes with a projection 1707 on the anchor to form a limit stop, preventing the spout 1105 from a full range of rotation about the anchor 1115. The set ring 1721 contains threads 1721 positioned on the inner surface of the set ring 1721, which interact with external threads 1723 on the connector tube 1709.

The connector tube 1709 may be a metal, such as brass. The connector tube 1709 is cylindrical and hollow, and contains tube threads 1723 located on the outer surface. The tube threads 1723 engage with the threads 1721 of the set ring 1703, releasably engaging the connector tube 1709 to the set ring 1703. The connector tube 1709 also contains a groove 1727 or a tube lip into which an elastomeric o-ring 1705 may be deposited. The o-ring 1705 may be sized so that it deforms when installed and the connector tube 1709 presses the o-ring 1705 against the inner surface of the anchor 1115. Proximate on opposite end of the connector tube 1709 as the threads 1723, the connector tube 1709 contains a groove 1719 to interact with one or more fingers 1717 of the bearing 1711, allowing the bearing 1711 to rotate relative to the connector tube 1709.

The bearing 1711 is cylindrical, and may be formed of a plastic material. The bearing 1711 contains inward facing fingers 1717 and outward facing fingers 1713. The inward facing fingers 1717 engage with the groove 1719 on the outer surface of the connector tube 1709, such that the connector tube 1709 may rotate freely around the bearing 1711. When the connector tube 1709 and bearing 1711 are installed within the anchor 1115, the outward facing fingers 1713 flex inward while the bearing 1711 travels the length of the anchor 1115, and flex outward to engage with the anchor windows 1715. The outward facing fingers 1713 are angled so that an amount of upward force will flex the outward facing fingers 1713 inwardly and remove the outward facing fingers 1713 from the anchor windows 1715. The inward facing fingers 1717 are angled so that disengagement of the inward facing fingers 1717 from the groove 1719 on the outer surface of the connector tube 1709 requires more force than disengagement of the outward facing fingers 1713 from the anchor windows 1715. This allows for disassembly or removal, so that the user may apply upward force to the spout 1105, and the outward facing fingers 1713 disengage from the anchor windows 1715 before the inward facing fingers 1717 disengage from the groove 1719 on the outer surface of the connector tube 1709, allowing the bearing 1711 to remain in communication with the connector tube 1709 while the connector tube 1709 and spout 1105 are lifted out of the anchor 1115.

The spout 1105 may be a metal or a plastic, and may be in the shape of a cylinder. The spout 1105 is hollow to allow for the outlet conduit 121 to extend from the bottom surface 127 of the mounting deck, through the anchor 1115, through the connector tube 1709, into the first opening 1731 of the spout 1105, through the spout 1105, and to the second opening 1733 of the spout 1105. The outlet conduit 121 may terminate with an aerator or other liquid management device. In an embodiment, the outlet conduit 121 is fixed within the spout 1105. In another embodiment, the outlet conduit 121 is not fixed, may be attached to a removable device such as a sprayer, and may be pulled out of the second opening 1733.

During installation of the spout assembly 1101, the set ring 1703 is fixed within the spout 1105, near the first opening 1731. The connector tube 1709 is installed in the spout 1105, so that the threads of the connector tube 1709 engage with the threads of the set ring 1703. The o-ring 1705 may be placed on the tube, 1709 and be partially constrained by a lip 1727 or other projection on the connector tube 1709.

The ring 1701 is pressed onto the bottom surface of the anchor 1115, so that the ring snap fingers flex outwardly and pass through the anchor openings. When the projections on the ring snap fingers reach the inner surface of the anchor through the anchor openings, the ring snap fingers flex inwardly so that the projections abut the inner surface of the anchor, releasably fixing the ring 1701 to the anchor 1115. The elastomeric or foam ring (not shown) may be placed in the groove 1729 on the underside of the ring 1701.

To mount the anchor 1115, the cleats 117a and 117b are oriented in retracted positions and are nested within respective supports, and the anchor 1115 body is passed through the mounting deck 111 from above. The ring 1701 bottom surface is sized so that it is wider than the opening through the mounting deck 111, or additional material is used to fill in the opening through the mounting deck 111 so that the ring 1701 bottom surface contacts the upper surface 1215 of the mounting deck 111. The attachment posts 217a and 217b are rotated clockwise such that the cleats 117a and 117b rotate out of the anchor 115 to extended positions outside of respective supports. Continued clockwise rotation causes the cleats 117a and 117b to move upwardly along the length of the respective post 217a and 217b such that the upper surfaces 703 of the cleats 117a and 117b engage the lower surface 127 of the mounting deck 111, thereby clamping the anchor 1115 and the mounting deck 111 between the upper surfaces of the cleats 117a and 117b and the anchor 1115.

The outlet conduit 121 is positioned to extend through the void in the anchor 1115 from the top surface 1215 of the mounting deck 111 to the bottom surface 127 of the mounting deck. The spout assembly 1101 is positioned over the anchor 1115 so that the connector tube 1709 extends into the void of the anchor, and the anchor projections 1707 compliment the projections of the ring. The outward facing fingers 1717 of the bearing 1711 flex inward while the bearing 1711 is moved through the void of the anchor 1115, and the outward facing fingers 1713 of the bearing 1711 flex outward when the fingers 1713 interact with the anchor windows 1715. The spout 1105 may overlap the lip 1725 of the ring 1701, so that the anchor 1701 is not visible from the upper surface 1215 of the mounting deck 111. The user may rotate the spout 1105, rotating the set ring 1703 and rotating the connector tube 1709, and the bearing 1711 may stay static with respect to the connector tube 1709, as the bearing 1711 is releasably fixed to the anchor 1115, but the spout 1105 is prevented from over rotation by the interactions of the projections 1707 of the anchor 1115 and the projections of the set ring 1703. The inward facing fingers 1717 of the bearing 1711 prevent upward and downward movement of the spout assembly 1101, although the outward facing fingers 1713 may decouple from the anchor windows 1715 during disassembly or removal.

The spout structure 1101 and/or the valve structure 1103 may include capacitive sensors. The valve structure 1103 may include, for example, a light emitting diode indicator 1213 to provide the status of the capacitive sensor. Connector 1111 may extend from the valve structure 1103 and through the anchor 1113 to connect with a processor (not shown).

Although the disclosure has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the spirit and scope of the disclosure as described and defined in the following claims.
