(14) A faucet assembly 10 in accordance with the present disclosure includes a liquid dispenser 12, a valve assembly 14, and a handle assembly 16 as shown, for example, in FIGS. 1, 2 and 8. Valve assembly 14 is coupled to liquid dispenser 12 and is configured to move relative to liquid dispenser 12 to control the discharge of liquid 104 stored in a container 100 that liquid dispenser 12 is coupled to, as suggested in FIGS. 2 and 8. Handle assembly 16 is coupled to valve assembly 14 to define a valve space 19 therebetween. Handle assembly 16 is configured to move valve assembly 14 from a closed position as shown in FIG. 1 to an open position to allow liquid 104 in container 100 to flow out through liquid dispenser 12. Handle assembly 16 includes a lever 20 that extends downward and outward from where handle assembly 16 is coupled to valve assembly 14 to provide accessible control of valve assembly 14 at a height suitable for compliance with ADA Guidelines.

(15) When handle assembly 16 is in a first position, as shown in FIG. 1, valve assembly 14 is in the closed position and discharge of liquid 104 through a first or, as shown, horizontal flow channel 18 in liquid dispenser 12 is blocked by valve assembly 14. When a user-applied force 11 is applied to handle assembly 16 by lifting up on the downwardly extending lever 20, handle assembly 16 is moved to a second position and valve assembly 14 is moved to the open position that does not block horizontal flow channel 18, as shown in FIG. 2. When valve-assembly 14 is in the open position, liquid 104 stored in container 100 can flow through liquid dispenser 12 and be discharged out of faucet assembly 10.

(16) Handle assembly 16 includes lever 20, a base 22, and one or more pivot pins 24, as seen in FIGS. 3-7. Base 22 is coupled to lever 20 and configured to extend downward toward liquid dispenser 12 to abut against liquid dispenser 12 when handle assembly 16 is in the first position. Pivot pins 24 are appended to base 22 and are configured to be coupled to valve assembly 14 in order to provide movement of valve assembly 14 when handle assembly 16 is moved by user-applied force 11.

(17) As shown, for example, in FIGS. 1, 2, 4 and 7, lever 20 includes a gripping portion 26, a connecting portion 28, and an angled extender 30. Angled extender 30 is appended to the top of gripping portion 26 and is appended to the bottom of connecting portion 28 to bridge gripping portion 26 and connecting portion 28 together, as seen in FIGS. 3-7. Gripping portion 26, connecting portion 28 and angled extender 30 are configured such that, when a user actuates lever 20 of handle assembly 16 with user-applied force 11, gripping portion 26, connecting portion 28 and angled extender 30 move together as a unified piece.

(18) Gripping portion 26 includes a front face 32 and a back face 34. Front face 32 may, in at least one embodiment, include indicia 36 that instruct a user on how to actuate handle assembly 16. Alternatively, the indicia 36 could be left off of the front fact 32. As shown in FIGS. 4-7, back face 34 of gripping portion 26 may, in at least one embodiment, include a contoured grip 38 to provide a place for a user's fingers to grip when actuating handle assembly 16. Contoured grip 38 includes ribs 40 to accommodate a range of user's finger dimensions, positive gripping, and comfort. As shown in FIG. 4, ribs 40 are arranged to extend in an inward direction toward liquid dispenser 12 when handle assembly 16 is coupled to valve assembly 14 and liquid dispenser 12.

(19) Angled extender 30 is slightly angled in an outward direction away from liquid dispenser 12. Gripping portion 26 is coupled to angled extender 30 at a connection plane 31, causing gripping portion 26 to be angled further away from liquid dispenser 12. Gripping portion 26 is angled downward at a point below connection plane 31 to provide an indentation for a user's finger to easily grasp contoured grip 38 between gripping portion 26 and liquid dispenser 12.

(20) Connecting portion 28 includes a side panel 42 and a top panel 44, as shown in FIGS. 3 and 4. The bottom of side panel 42 is appended to the top of angled extender 30 at a connection plane 33. The top of side panel 42 is appended to top panel 44 at a connection plane 35. Connecting portion 28 is arranged to interconnect gripping portion 26 to base 22 of handle assembly 16 to cause valve assembly 14 coupled to base 22 to move relative to liquid dispenser 12 in response to user-applied force 11 on gripping portion 26.

(21) Side panel 42 and top panel 44 are arranged to cause side panel 42 and gripping portion 26 to extend in a downward and outward direction from top panel 44 such that handle assembly 16 extends below valve assembly 14 when coupled to valve assembly 14 and can be activated at a lower height, compared to other prior art faucet which might have a substantially vertically oriented handle, to comply with ADA Guidelines. In illustrative embodiments, side panel 42 extends downward at a handle angle 17 that is generally greater than 90 degrees from top panel 44 along a top axis 13, preferably at a handle angle 17 between approximately 100 degrees and 110 degrees. Handle angle 17 causes side panel 42 and gripping portion 26 to extend in an outwardly direction away from a valve axis 15 to facilitate a user's finger in actuating lever 20.

(22) Side panel 42 includes a front face 45 and a back face 46, as shown in FIGS. 4-6. Back face 46 includes an abutment nub 48 arranged to extend in an inward direction toward liquid dispenser 12 when faucet assembly 10 is assembled. In particular, abutment nub 48 is coupled to lever 20 and arranged to abut against liquid dispenser 12 when handle assembly 16 is in the first position, blocking movement of lever 20 in a rearward direction toward liquid dispenser 12, as shown, for example, in FIGS. 1, 4 and 6. In this way, abutment nub 48 may act to block unintended operation or actuation of handle assembly 16 in a rearward direction toward liquid dispenser 12. In illustrative embodiments, abutment nub 48 may abut against any part of liquid dispenser 12 when handle assembly 16 is in the first position.

(23) Top panel 44 of connecting portion 28 includes a shaft window 50 that is formed to include a shaft orifice 52. Shaft orifice 52 is arranged to open into valve space 19, as shown, for example, in FIG. 1. Shaft orifice 52 is configured to be substantially aligned with valve axis 15 and is of substantial width to allow for a portion of valve assembly 14 to travel through shaft orifice 52 during assembly or use.

(24) Base 22 of lever 20 includes guide rails 54 and cam mechanism 56. As shown, for example, in FIGS. 4-7, guide rails 54 are appended to side panel 42 and top panel 44 and arranged to extend in a downward direction toward liquid dispenser 12. Cam mechanism 56 is appended to guide rails 54 and top panel 44. When handle assembly 16 is in the first position, guide rails 54, top panel 44, side panel 42, cam mechanism 56 and liquid dispenser 12 combine to define valve space 19.

(25) As illustrated in FIGS. 1 and 6, guide rails 54 are arranged to abut against the top of liquid dispenser 12 when handle assembly 16 is in the first position, thereby blocking handle assembly 16 from downward gravitational movement. In this way, valve assembly 14 is secured in the closed position to block liquid from flowing through liquid dispenser 12.

(26) Cam mechanism 56 includes curved cam surface 58 configured to facilitate intentional and/or controlled operation of handle assembly 16 when user-applied force 11 is applied to handle assembly 16. As shown in FIG. 2, cam surface 58 is configured to rotatably abut against the top of liquid dispenser 12 when user-applied force 11 is applied to handle assembly 16 to allow for controlled and/or predictable operation of faucet assembly 10. In illustrative embodiments, curved cam surface may include a generally uniform radius of curvature 21, designed to allow the valve to open or crack when approximately 5 in/lbs of force is applied to the handle assembly 16.

(27) As shown, for example, in FIGS. 6 and 7, pivot pins 24 are appended to an interior surface 55 of guide rails 54 and are generally in parallel alignment with shaft orifice 52 along valve axis 15. Pivot pins 24 are configured to be integrally formed and couple the handle assembly 16 to valve assembly 14 in order to facilitate movement of valve assembly 14 through movement of handle assembly 16. The pivot pins could, alternatively, be configured as a separate rod or pair of rods extending through a least one of the side walls 54.

(28) Valve assembly 14 may be configured similar to traditional valve assemblies in traditional faucets. In illustrative embodiments, valve assembly 14 includes an operating shaft 60 and a valve plug 62. As shown in FIGS. 1 and 2, operating shaft 60 is coupled to valve plug 62 at a plug-receiving end 64 of operating shaft 60. Operating shaft 60 also includes a handle-receiving end 66 to couple valve assembly 14 to handle assembly 16. In particular, handle-receiving end 66 includes a pin groove 68 to securably receive pivot pins 24 of handle assembly 16 to lock handle assembly 16 onto valve assembly 14.

(29) Operating shaft 60 is configured to move up and down along valve axis 15 when handle assembly 16 is actuated. When user-applied force 11 is applied to handle assembly 16, lever 20 rotates up about pivot pins 24. Such rotation causes cam mechanism 56 to engage with liquid dispenser 12 to facilitate efficient movement of handle assembly 16. Movement of handle assembly 16 causes pivot pins 24 connected to base 22 to move upward along valve axis 15. As pivot pins 24 are connected to pin groove 68 of operating shaft, operating shaft 60 also moves upward along valve axis. Faucet assembly 10 is arranged to prevent movement of operating stem 60 in a vertically upward direction until the user's hand manually moves handle assembly 16 by applying user-applied force 11 in order to prevent unintended opening of the faucet assembly 10.

(30) Valve plug 62 is coupled with operating shaft 60 such that both valve plug 62 and operating shaft 60 are movable along valve axis 15 when handle assembly 16 is actuated. Valve plug 62 includes an annular side wall 70 that is configured to block the flow of liquid 104 through liquid dispenser 12 when valve assembly 14 is in the closed position, as seen in FIG. 1. When handle assembly 16 is moved to the second position to move valve assembly 14 to the open position, valve plug 62 moves upward with operating shaft 60 to allow flow of liquid through liquid dispenser 12, as shown in FIG. 2. In illustrative embodiments, valve plug 62 is coupled to operating shaft 60 through a shaft-receiving orifice 72 in a top wall 74 of valve plug 62. In particular, plug-receiving end 64 of operating shaft 60 is lockably coupled into shaft-receiving orifice 72 of valve plug 62.

(31) Liquid dispenser 12 includes a dispenser body 76, a nozzle 78, and a closure top 80. Dispenser body 76 and nozzle 78 are coupled together at substantially a right angle, as shown in FIGS. 1, 2 and 8. Closure top 80 can be coupled to nozzle 78 to enclose liquid dispenser 12.

(32) As shown in FIG. 8, dispenser body 76 is coupleable to an outlet tube 106 of container 100. Dispenser body 76 includes an annular body wall 84 and threading 82 appended to one end of annular body wall 84. Annular body wall 84 defines horizontal flow channel 18 to allow liquid 104 to flow through liquid dispenser 12 in order to dispense liquid 104 from container 100. In illustrated embodiments, dispenser body 76 may be coupled to outlet tube 106 via a coupling washer 108 that engages with threading 82 of dispenser body 76.

(33) Nozzle 78 of liquid dispenser 12 is of similar configuration as found in traditional faucet assemblies and includes an opening 88, an open top end 77, and an annular nozzle wall 87 formed to include a vertical flow channel 86. As illustrated, for example, in FIGS. 1 and 2, open top end 77, opening 88 and vertical flow channel 86 are substantially in parallel alignment along valve axis 15. When valve assembly 14 is in the closed position, valve plug 62 blocks all liquid flowing from horizontal flow channel 18 of dispenser body 76 from entering vertical flow channel 86. When valve assembly 14 is in the open position, liquid is allowed to flow from horizontal flow channel 18 into vertical flow channel 86 and out through opening 88.

(34) Closure top 80 includes an annular skirt 90, a top wall 92, and an annular lip 94. As illustrated in FIGS. 1, 2 and 8, annular skirt 90 depends from the outer circumference of top wall 92 and is configured to be secured onto top end 77 of nozzle 78. Annular lip 94 is coupled to top wall 92 inside the circumference of annular skirt 90. Annular lip 94 extends downward from top wall 92 and is substantially parallel to annular skirt 90.

(35) Annular lip 94 defines a valve-assembly orifice 96 in closure top 80. Annular lip 94 and valve-assembly orifice 96 are generally aligned with valve axis 15. As shown in FIGS. 1 and 2, operating shaft 60 is arranged to extend through valve-assembly orifice 96 defined by annular lip 94 and into valve space 19 so that operating shaft may be engagably coupled to handle assembly 16 to move valve assembly 14 from the closed position to the open position. Annular lip 94 creates frictional engagement with operating shaft 60 to ensure operating shaft 60 is properly aligned with valve-assembly orifice 96 and valve axis 15.

(36) FIG. 8 illustrates use of faucet assembly 10 in a servicing or cleaning position. In particular, handle assembly 16 has been rotated approximately 180 degrees around valve axis 15 to a third position. In this third position, lever 20 of handle assembly 16 abuts against washer 108 and outlet tube 106 to maintain handle assembly 16 at the relative height and rotation as it is in the second position but without user-applied force 11. By maintaining handle assembly 16 in this third position, valve assembly 14 is maintained in the open position and allows liquid 104 to flow through liquid dispenser 12 without user-applied force 11. Such third position is advantageous when, for example, cleaning or emptying container 100 for service.

(37) Faucet assembly 10 is assembled in a series of illustrative operations. In a first operation, valve assembly 14 is inserted into top end 77 of nozzle 78 along valve axis 15. Closure top 80 is the coupled to nozzle 78 and operating shaft 60 is positioned through valve-assembly orifice 96 of closure top 80 to extend through and out of liquid dispenser 12. In a second operation, handle assembly 16 is then coupled to valve assembly 14 by extending operating shaft 60 in an upward direction through shaft orifice 52 of lever 20 until pin groove 68 of operating shaft 60 lines up with pivot pins 24 of handle assembly 16. During assembly, operating shaft 60 is arranged to extend out of valve space 19 through shaft orifice 52 so that pivot pins 24 can be properly aligned with pin groove 68 of operating shaft 60. Pivot pins 24 then can be positioned into pin groove 68 to retainably couple valve assembly 14 to handle assembly 16. In a third operation, dispenser body 76 of liquid dispenser 12 is coupled to outlet tube 106 of container 100 to allow selective dispensing of liquid 104 from container 100.

(38) As an example of use of faucet assembly 10, handle assembly 16 begins in the first position with the valve assembly 14 in a closed position blocking discharge of liquid 104 through liquid dispenser 12. In a first stage of use, the user lifts handle assembly 16 in an upward direction relative to liquid dispenser 12 to the second position by user-applied force 11, as shown in FIG. 2. Such movement causes valve assembly 14 to move upward to an open position and valve plug 62 ceases to block liquid from moving through liquid dispenser 12. After use is complete, the user stops applying user-applied force 11 and allows handle assembly 16 to return to the first position, causing valve assembly 14 to return to the closed position. When a user wishes to service or empty container 100, the user rotates handle assembly 16 approximately 180 degrees until handle assembly 16 can be maintained in the third position without user-applied force 11 by securing handle assembly 16 in an open position to be abutting against outlet tube 106. This enables valve assembly 14 to be maintained in the open position to allow liquid 104 to freely flow through liquid dispenser 12.
