The soap conduit 45 includes a hose 47 connected to the soap control unit 111 that extends through a lid 48 of the soap supply 41 and extends into the soap supply 41. The hose 47 has an end piece or strainer 49 that includes a filter, which is positioned proximate to, but above the bottom of the soap supply 41. The lid 48 has a cap 50 that may be in the form of a quick-connect fitting, connecting to the lid 48 by a threaded connection and holding the hose 47 in place. This quick-connect cap 50 permits the soap supply 41 to be changed quickly and easily, by disconnecting the cap 50, removing the empty soap supply 41, and reconnecting the cap 50 to a new soap supply 41. An angled fitting 53 extends through the cap 50 and connects to the hose 47 to permit the hose 47 to extend through the cap 50. The angled fitting 53 may be at a 90° or approximately 90° angle in one embodiment, and is stiff and rotatable to permit rotation of the hose 47 and/or the soap supply 41 without twisting or kinking of the hose 47 or the inlet hose 55 connected to the angled fitting 53. A shroud 51 is connected to the bottom of the lid 48 in this embodiment, which may be in the form of a length of rigid pipe (e.g., PVC). The soap supply 41 also includes a fitting 54 connected to the lid 48 and extending through the lid 48, which is engaged with and supports the shroud 51 and also is threaded for connection to the cap 50. The hose 47 extends downward through the shroud 51, and the end piece 49 is held within the shroud 51 by a rubber grommet 52 or other retainer. The bottom end of the shroud 51 is located just above the bottom of the soap supply 41 (e.g., 0.5 inch), and the grommet 52 holds the end piece 49 just above the bottom of the shroud 51 to be in communication with the soap within the soap supply 41 until the soap supply 41 is nearly empty. This configuration of the shroud 51 and the end piece 49 helps to protect the hose 47 and the end piece 49 and prevent coagulated soap from entering the hose 47.

The mounting assembly 70 supporting the basin assembly 11 includes one or more internal supports that engage the pony wall 101 and support the basin assembly 11 from below, including mounting brackets 71 and end brackets 72, as shown in FIGS. 14-17. The end brackets 72 are fastened to the pony wall 101, such as by fasteners and/or adhesive, at the ends of the basin assembly 11, and one or more mounting brackets 71 are located between the end brackets 72 to support the center portions of the basin assembly 11. In the embodiment illustrated, the mounting assembly 70 includes two mounting brackets 71 between the end brackets 72. The end brackets 72 are gusseted arms extending longitudinally out from the pony wall 101 in this embodiment, and are mounted between the basin assembly 11 and the apron 34. The mounting brackets 71 are gusseted arms that extend longitudinally outward and upward at a sloped angle from the pony wall 101. Each mounting bracket 71 has a notch 73 on the top surface that receives a protrusion 74 formed by the underside of the trough 90 on the underside of the basin assembly 11. The protrusion 74 has different depths at different locations, due to the sloped contours of the trough 90. The notch 73 in this embodiment has a depth sufficient to permit the mounting bracket 71 to accommodate the protrusion 74 while positioned at nearly any location along the lateral width of the basin assembly 11. In the embodiment shown, the mounting bracket 71 cannot be placed directly under the drain 17 due to the dimensions of the drain 17, but in other embodiments, the degree of recession of the drain 17 and/or the depth of the notch 73 may be modified to permit this mounting as well. The sloped mounting brackets 71 extend along the underside of the sloping surface 92 of the basin assembly 11 and thereby support the basin assembly 11. Each mounting bracket 71 also has an upwardly-extending projection 75 that extends into the underside of the front 14 of the basin assembly 11 behind the apron 34, as shown in FIG. 2. Each projection 75 may have a plate 75A at the end thereof, for supporting and/or connecting to the underside of the basin assembly 11, as shown in FIG. 17. The mounting assembly 70 also includes panels 76 covering the underside of the basin assembly 11, as well as the mounting brackets 71 and the end brackets 72. The geometries of the mounting bracket(s) 71 and the end brackets 72 are configured to support the basin assembly 11 in a configuration that complies with the Americans with Disabilities Act (ADA), to permit case of use of the hand washing station 10.

FIGS. 28-30 illustrate one embodiment of a drain 17 configuration that permits use of the mounting bracket 71 directly under the drain 17. The hand washing station 10 in this embodiment has a drain adapter 59 having a body 59A, which may be molded from solid surface material, attached (e.g., via adhesive) to the rear of the rear wall 93 of the basin assembly 11 at the location of the drain 17. The drain adapter 59 is sealed around the drain and generally includes an internal cavity 59B in communication with the drain 17 to receive liquid from the drain 17, as well as a drain pipe connection 59C in communication with the cavity 59B. The drain adapter 59 is configured for connection to the drain pipe 19 (not shown in FIGS. 28-30) via the drain pipe connection 59C. In one embodiment, the drain adapter 59 is connected to the basin assembly 11 at a location such that the bottom surface of the body 59A does not extend below an underside of the bottom wall of the basin assembly, e.g., below the bottom of the protrusion 74 in the embodiment of FIGS. 28-30. As shown in FIG. 29, the bottom surface of the body 59A of the drain adapter 59 in this embodiment is flush with the bottom of the protrusion 74 formed by the trough 90 or otherwise does not extend substantially below the bottom of the protrusion 74. The body 59A is pointed similarly to the protrusion 74, as seen in FIG. 29. This configuration eliminates interference with the mounting bracket 71 that would prevent the mounting bracket 71 from being used directly under the drain 17, in contrast with the drain adapter 59 seen in FIG. 23. Other configurations are possible as well.

FIGS. 16-19 illustrate a method of mounting the basin assembly 11 on the pony wall 101. As shown in FIG. 16, the mounting brackets 71 and the end brackets 72 are mounted on the pony wall 101, and the basin assembly 11 is then placed on top of the mounting brackets 71 and the end brackets 72 as shown in FIG. 17. The basin assembly 11 may then be fixed to the mounting brackets 71 and the end brackets 72, such as by fasteners and/or adhesives. When the basin is mounted on the mounting brackets 71 and the end brackets 72, a flange 77 extending rearward on the top 12 of the basin assembly 11 extends over the top surface 102 of the pony wall 101 and is fixed to the top surface 102, as shown in FIG. 18. In one embodiment, the flange 77 is a free flange that is joined to other portions of the basin assembly 11 along only a single edge, at the front of the flange 77, i.e., no side walls or surfaces are connected to the left and right sides of the flange 77. The underside of the flange 77 may be fixed to the top surface 102, such as by fasteners and/or adhesives. As shown in FIG. 18, the basin assembly 11 may be mounted so a slight space exists between the flange 77 and the top surface 102 of the pony wall 101, so the height of the adhesive connecting the flange 77 to the top surface 102 does not cause misalignment of the basin assembly 11. As also shown in FIG. 18, a spacer or backer 78 is also fixed to the top surface 102 of the pony wall 101 in the space between the flange 77 and the main wall 100. The backer 78 may have the same lateral width as the flange 77 and/or may fill most or all of the space between the flange 77 and the main wall 100. A shelf 79 is then connected on top of the flange 77 and the backer 78 to cover part or all of the flange 77 and the backer 78, and the shelf 79 may be fixed in place by fasteners and/or adhesives. The backer 78 and/or the flange 77 may be shimmed or otherwise leveled to ensure that the shelf 79 is leveled properly. In one embodiment, the shelf 79 is slightly angled downward toward the front 14 of the basin assembly 11, such that any liquid on the shelf 79 will naturally flow off of the shelf 79 into the basin assembly 11. This creates a clean and dry shelf 79 that is better suited for holding a user's belongings during washing of hands. Further, the front of the shelf 79 hangs slightly forward of the rear wall 93 of the basin assembly 11, and in one embodiment, lighting (e.g., LED lights) may be fixed to the overhanging underside 58 of the shelf 79. For example, the overhanging underside 58 of the shelf 79 may include a rabbit or recess that may include a strip of LED lights or another lighting device. Such lighting may include a power module, which may be mounted in the cavity 103. The basin assembly 11 may also be fixed to the pony wall 101, such as by adhesive, to further increase strength and stiffness. A basin assembly 11 mounted in this configuration has substantially increased strength of connection to the pony wall 101, as well as substantially increased stiffness.

FIGS. 2, 4-10, and 12 illustrate components of the spout mounting assembly 80 for supporting the spouts 32, 43, 63 for the water dispenser 30, the soap dispenser 40, and/or the hand dryer 60. The spouts 32, 43, 63 may be mounted close to or above the level of the shelf 36, but below the top of the rear wall 93 (which is higher than the shelf 36). Each of the spouts 32, 43, 63 may be mounted to the basin assembly 11 using at least one fixed fastener and at least one removable fastener in some embodiments. It is understood that the terms “fixed fastener” and “removable fastener” do not necessarily imply that the fasteners are fixed to or removable from every related component, but only that the connections created by such fasteners are effectively fixed or removable, respectively. Each of the spouts 32, 43, 63 has a removable fastener in the form of one or more bolts or threaded studs 81 extending from the rear side of the spout 32, 43, 63, which may be received in threaded holes 82 in the rear of the spout 32, 43, 63. The basin assembly 11 has fixed fasteners 83 extending forward from the rear wall 93, as shown in FIGS. 5 and 9, which are in the form of Christmas tree rivets, which are configured to be inserted into holes with ease but engage the insides of the holes to resist pulling the fixed fasteners 83 out of the holes. These rivets include an enlarged head 83A with a shaft 83B extending from the head 83A, and flexible fingers 83C extending from the shaft 83B. The fingers 83C extend at an angle outward and toward the head 83A, such that insertion of the shaft 83B into a hole is easily accomplished, but the angles of the fingers 83C cause the fingers to “grip” the inside of the hole and resist retraction. The fixed fasteners 83 in the illustrated embodiment extend through holes 84 in the rear wall 93 and are fixed to the rear wall 93. When one of the spouts 32, 43, 63 is to be mounted on the basin assembly 11, the spout 32, 43, 63 can be pushed onto the fixed fasteners 83 such that the fixed fasteners 83 are inserted into holes 85 in the rear side of the spout 32, 43, 63. The fixed fasteners 83 thereby hold the spout 32, 43, 63 in place so that installation can be completed from the inside of the chase 103. When the spout 32, 43, 63 is pushed onto the fixed fasteners 83, the studs 81 also extend through holes 84 in the rear wall 93 of the basin assembly 11. Thus, this configuration permits the spouts 32, 43, 63 to be easily installed by a single worker operating both outside and inside of the chase 103, as well as strengthening the overall connection strength of the spouts 32, 43, 63. The installation can be completed by threading alignment nuts 86 onto the ends of the studs 81 from behind the pony wall 101 and inside the chase 103.

The spout mounting assembly 80 also includes a reinforcing bracket 87 located on the inner surface of the rear wall 93, which may be mounted on the rear wall 93 by fasteners and/or adhesives. The reinforcing bracket 87 in FIGS. 2, 4-10, and 12 is a C-shaped or U-shaped metal channel beam extending laterally along the inside of the rear wall 93 and fastened near the ends of the reinforcing bracket 87. In another embodiment, the reinforcing bracket 87 may have a different shape or configuration, e.g., a flat plate, or may be made from a different material, such as the material of the basin (e.g., quartz). The reinforcing bracket 87 has passages 69 extending therethrough to permit passage of conduits and other components of the water dispenser 30, the soap dispenser 40, and the hand dryer 60. The fixed fasteners 83 are held in place behind the rear wall 93 by having heads 83A sandwiched between the rear wall 93 and the reinforcing bracket 87, as shown in FIG. 5. Additionally, as shown in FIG. 5, the reinforcing bracket 87 has holes 88 for receiving the studs 81 therethrough, and the holes 88 are countersunk and/or chamfered. The alignment nuts 86 have chamfered protrusions 89 on the front surface thereof, which are dimensioned to be tightly received in the chamfered portions of the holes 88, as shown in FIG. 5. This configuration ensures that the studs 81 are centered within the holes 88 and creates greater positional accuracy and stability for the studs 81 and thereby also for the spouts 32, 43, 63. This, in turn, enables the spouts 32, 43, 63 to be installed in a configuration that is nearly exactly perpendicular to the rear wall 93 of the basin assembly 11 and/or where all three of the spouts 32, 43, 63 extend at nearly exactly equal angles from the rear wall 93. Additionally, the spouts 32, 43, 63 can be mounted at nearly exactly the same rotational angles. For example, in one embodiment, all three spouts 32, 43, 63 can be mounted with less than 0.5° angular misalignment (cither longitudinally or rotationally) between the spouts 32, 43, 63. The alignment nuts 86 also have wide flanges 56 to contact the rear surface of the reinforcing bracket 87 and to ensure that adequate torque can be applied on the alignment nuts 86 against the reinforcing bracket 87. In another embodiment, the alignment nuts 86 may not include a flange 56, and may include a larger hex head instead. It is understood that the reinforcing bracket 87 may not be present, and the alignment nuts 86 may be connected to any surface with appropriate chamfered holes 88.

The air spout 63 includes additional mounting components for an adapter 65 to connect the stem 64 to the air spout 63, illustrated in FIG. 12. The adapter 65 has holes 66 extending therethrough and aligned with the studs 81 to receive the studs 81. The adapter 65 also has recesses 67 in the front surface configured to receive the alignment nuts 86 of the spout mounting assembly 80. The stem 64 is fixed to the adapter 65, and additional nuts 68 are fastened to the ends of the studs 81 to hold the adapter 65 in place in engagement with the mounting assembly 80.

As noted herein, some components of the hand washing station 10 of FIGS. 1-23 may be mounted within the cavity 104 in the pony wall 101 and/or within the chase 103. FIGS. 2, 4, and 13 illustrate some such components, and the hand washing station 10 may include a backing panel 106 connected to the inside of the pony wall 101 within the cavity 104 and an internal shelf 107 at the bottom of the cavity 104. As shown in FIG. 13, the water dispenser control unit 110, the soap control unit 111, the blower motor 61, and the dryer control unit 112 (within the blower motor 61) are mounted on the inside of the pony wall 101 within the cavity 104, and the water dispenser control unit 110 and the soap control unit 111 are both mounted on the backing panel 106. The backing panel 106 may be made from lumber, and the internal shelf 107 may be made from metal, in various embodiments. The soap supply 41 rests on the internal shelf 107 in this configuration.

FIGS. 24-26 illustrate another embodiment of a hand washing station 10 that is configured for mounting on a main wall 100 without a pony wall 101 or a chase 103.
