DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(54) An exemplary embodiment of a hands-free faucet control device is disclosed. FIG. 1 is a perspective view of a cabinet 10 with a sink 12 that would house the present invention. FIG. 2 is a perspective view of the cabinet of FIG. 1 now opened showing an embodiment of the present invention as a valve assembly 100 and a foot pedal assembly 102. As shown herein, two water lines 104a and 104b run into the valve assembly 100 and two water lines 106a and 106b run out of the valve assembly 100. This means that any of the two incoming lines could be either a hot or a cold water inlet line. Also, any two outgoing lines could be either a hot or cold water outlet line. It is noted herein, the position of the lines could be switched such that the bottom most lines are the inlet lines or alternatively could be the outlet lines.

(55) Referring now to FIG. 8, a continuously-formed injection molded valve housing 108 is shown. The valve housing 108 has two cylindrically-shaped apertures 110a and 110b disposed adjacent to one another. Each cylindrically-shaped aperture 110 has an open first end 112a and 112b opposite a frustoconically-shaped second end 114a and 114b. An axis of revolution 116a and 116b is defined through the cylindrically-shaped aperture 110 and frustoconically-shaped second end 114. Each frustoconically-shaped second end 114 has a wide end 118a and 118b opposite a narrow end 120a and 120b, where the wide end 118 is connected and contiguous to the cylindrically-shaped aperture 110.

(56) A first fluid connection port 122a and 122b is connected at the narrow end 120. Each cylindrically-shaped aperture 110 has a second fluid connection port 124a and 124b disposed between the narrow end 120 of the frustoconically-shaped second end 114 and the open first end 112 of the cylindrically-shaped aperture 110. The first and second fluid connection ports are in fluidic communication with an interior portion 126a and 126b of their respective frustoconically-shaped second ends 114. Each cylindrically-shaped aperture 110a and frustoconically-shaped second end 114a are not in fluidic communication with the adjacently disposed cylindrically-shaped aperture 110b and frustoconically-shaped second end 114b. The valve housing 108 may include continuously-formed fastening holes 128 for attaching the valve housing 108 to various structures.

(57) Referring to FIG. 4, there are two valves 130a and 130b, where each valve is disposed within one of the respective cylindrically-shaped apertures 110 and frustoconically-shaped second ends 114. Each valve 130 is translatable along their respective axis of revolution 116. As best seen in FIGS. 6 and 7, each valve 130 has a proximal end 132 opposite a distal end 134. The valves 130 are simultaneously movable between a closed position as best seen in FIG. 32 and an open position as best seen in FIG. 31.

(58) Referring now to FIGS. 6 and 7, there are a pair of first fluidic seals 136a and 136b. As seen in FIG. 5, each first fluidic seal 136 is disposed between its respective valve 130 and the cylindrically-shaped aperture 110. The pair of first fluidic seals 136 prevent a fluid from flowing thereby.

(59) The pair of first fluidic seals 136 may comprise o-ring seals. Each first fluidic seal of the pair of first fluidic seals may comprise at least two o-rings disposed adjacently to one another as shown in FIGS. 6 and 7. The at least two o-rings increases the reliability of the fluid seal. However, it is understood that only one o-ring could be used, or even a plurality of o-rings used. It is also understood that the seal may be attached to the inside surface of the cylindrically-shaped aperture 110 instead of onto the valve 130. It is also understood that the seal may be shaped in other forms not being an o-ring. For example, a cylindrically-shaped elastomeric seal is possible. Furthermore, the elastomeric cylindrically-shaped seal could have integrated circumferential wipers that create the sealing action. As can be understood by those skilled in the art, many forms of seals are possible that are congruent with the teachings of this disclosure.

(60) Referring now to FIGS. 6 and 7, there are a pair of second fluidic seals 138a and 138b. As seen in FIG. 5, each second fluidic seal 138 is disposed between its respective distal end 134 of the valve 130 and the narrow end 120 of the frustoconically-shaped second end 114. The valves 130 open and close as they simultaneously translate as best seen in FIGS. 31 and 32. The valves 130 opening and closing either opens or stops fluidic communication between the first fluid connection ports 122 and the interior portion 126 of the frustoconically-shaped second ends 114. Again, the seals 138 (and 136) may be made of many rubber, rubber-like or elastomeric materials. Furthermore, the pair of second fluidic seals 138 may be fastened onto their respective distal ends 134 of the pair of valves 130 with a fastener 139 or the pair of second fluidic seals 138 may be molded (over-molded) onto their respective distal ends 134 of the pair of valves 130.

(61) As best seen in FIGS. 31 and 32, the frustoconically-shaped second ends 114 help in controlling the amount of water that is allowed to flow when the foot peddle 54 is activated. As the valves 130 retract, a gradual amount of flow area is created between the distal ends 134 of the valve 130 and the inside surface of the frustoconically-shaped second ends 114 such that the user can modulate the amount of water flowing there through with simply their foot. Previous designs were incapable of such precision and control of the water flow rate with the use of one's foot. As can be seen in FIGS. 6 and 7, the distal ends 134 of the valves 130 are also frustoconically-shaped such that they match the angle and shape of the frustoconically-shaped second ends 114 of the valve 130. In this way, a gradual control of the valve assembly 100 is achieved.

(62) As best seen in FIG. 4, there are a pair of springs 140a and 140, where each spring 140 presses against their respective valves 130 biasing the valves 130 towards the closed position. The spring 140 may be a compression spring or any other equivalent structure that creates a preload.

(63) FIGS. 33-36 show an exemplary foot pedal assembly 102 of the present invention. A pedal 54 is designed to remain in an upright position and the user simply steps upon the pedal 54 to open the valve assembly 100. As the pedal 54 moves downward, it pulls on the pull wire 142 of the sheathed guide wire 144 which then pulls or rotates the valve 130 inside the valve housing 108.

(64) In this embodiment the pedal 54 remains upright because the bracket 56 is biased in an upright position. The bracket 56 acts as a support but also as a spring. The bracket 56 bends about corner 58. The bracket 56 is made of a flexible and resilient material such as spring steel, plastic such as reinforced nylon or the like. The pedal 54 is attached to a lever 60. Together the bracket 56 and lever 60 control the movement of the pedal 54. Also shown is a wire catch 62 that attaches to the distal end of the sheathed pull wire 32. The wire catch 62 is attached to the wire of the sheathed pull wire. The wire catch 62 can also be constructed as a slot, hole or aperture that the end of the pull wire second end 152 can connect to.

(65) Another novel feature of the present invention is the addition of a hold down feature. A switch 64 is positioned directly above the pedal 54. When a user steps upon the pedal 54, they may also then move their foot to the side activating the rotatable/pivotable switch 64 to keep the pedal 54 down without having to keep one's foot constantly upon the pedal 54. As can be seen in these views, the switch 64 includes a protrusion 66 that engages into a notch 68 formed into the bracket 56. Several notches 68 may be used to provide numerous levels of on.

(66) FIGS. 37-40 show another embodiment of a foot pedal assembly 102. The function of FIGS. 37-40 is similar to FIGS. 33-36 while the structure is different. The sheathed guide wire 144 is designed to come down in the middle of the foot pedal assembly 102. The bracket 56 still flexes but is shaped differently. The foot pedal assembly of FIGS. 37-40 is designed to be attached to the underside of the floor of the cabinet whereas the embodiment in FIGS. 33-36 is designed to be attached to the vertical kickboard at the base of the cabinet. It will be understood by those skilled in the art that a spring or bias mechanism could also be used to bias the pedal 54 in an upright manner.

(67) FIGS. 41 and 42 is yet another embodiment of a foot peddle assembly 102 which is slightly different than the other embodiments. Here, the peddle 54 is pivotably coupled to the bracket 56. The bracket 56 is designed to attach to a vertical surface such as the kickboard at the base of the cabinet 10. As can be seen, fasteners 146 can be used to screw into the wood of the kickboard.

(68) FIG. 43 is yet another embodiment of a foot peddle assembly 102. Here, the bracket 56 is designed to mount to the topside of the floor 148.

(69) As shown herein, there are many embodiments of a foot pedal assembly 102 that includes a foot peddle bracket 56 attachable to a structural support, where the structural support for the foot peddle bracket can be a wall, a cabinet or a floor. Accordingly, one skilled in the art could modify any of the disclosed concepts to create new versions that operated in different ways but achieved the same goals and functionality. Also, the foot activated hold-down switch 64 may be pivotably or flexurally attached to the foot pedal bracket 56 as shown in FIGS. 42 and 43. Here, the foot activated hold-down switch 64 penetrates through a hole 69 in the foot peddle 54. The extension 71 can then capture the top surface of the foot peddle 54 when the foot peddle 54 is depressed. The foot peddle 54 will stay down until the user pushes the switch 64 to the side and releasing the foot peddle 54. Referring back to FIG. 40, the foot activated hold-down switch 64 may include a protrusion 66 configured to engage a notch 68 located on the foot peddle bracket 56 as shown in FIG. 40. In this case, the user would push the foot peddle 54 downward and then then push the switch 64 to the side to force the protrusion 66 to engage the notch 68. A spring can be biased against the switch 64 to either force it to remain closed or force it to remain open, depending on the user's preference. As can now be seen, a multitude of hold-down switches can be devised and used with the disclosed structures.

(70) Referring back to FIG. 5, a pull wire 142 is connected at a pull wire first end 150 to the proximal end 132 of the valve 130 and connected at a pull wire second end 152 to the foot pedal assembly 102. Movement of the foot pedal 54 to the down position by a user moves the valves 130 to the open position. The pull wire 142 may comprise a sheathing 144 that allows the pull wire 142 to easily translate and move easily within.

(71) Referring now to FIG. 10, other exemplary embodiments may include a cap 154 attached to the valve housing 108 disposed at the open first ends 112. The cap 154 includes a pair of holes 156 which are aligned with the proximal ends 132 of the two valves 130. The cap 156 can be adhered, pressure fit, bonded or fastened to the valve housing 108 through fastener holes 157. As best seen in FIG. 4, the pair of springs 140 are captured between the cap 154 and their respective valves 130.

(72) As seen in FIG. 3, a pull wire connector 158 may be attached at a middle portion 160 to the pull wire first end 150. The pull wire connector 158 has a left portion 162 opposite a right portion 164 about the middle portion 160. As shown in FIG. 5, the left portion 162 is connected to the proximal end 132a of one of the two valves 130a, and the right portion 164 is connected to the proximal end 132b of the other of the two valves 130b. Another embodiment of the pull wire connector 158 is shown in FIGS. 9, 13 and 14. Here, there are holes 166 for fasteners to extend there through. A slot 168 allows the pull wire 142 to be inserted such that the pull wire first end 150 can be captured in the recess 170. The pull wire first end 150 can include an enlarged end that is either crimped or fastened to the pull wire 142. This end can also be described as a ferrule, which is an enlarged ring or cap, typically a metal one, that strengthens the end of the wire and prevents it from splitting, fraying or wearing. Then the enlarged end is captured into the recess 170 such that when the pull wire 142 is pulled it will move the pull wire connector 158 and also the valves 130 which are attached as well.

(73) As best seen in FIGS. 3 and 4, a bracket 172 may be attached to the valve housing 108. The bracket includes a pull wire alignment aperture 174 disposed above the middle portion 160 of the pull wire connector 158. The pull wire alignment aperture 174 can be a slit as shown here or a hole or other various sized aperture. Then, a pull wire tensioner 176 may be disposed within the pull wire alignment aperture 174 of the bracket 172. The pull wire 142 is captured and disposed through the pull wire tensioner 176, where the pull wire tensioner 176 is adjustably positioned in a translational direction which can move closer to and further from the pull wire connector 158 thereby adjusting the tension of the pull wire 142.

(74) Another embodiment of a pull wire tensioner 176 is shown in FIG. 23. Here, the pull wire tensioner 176 has an enlarged head 178 that can be grasped with a threaded end 180. A slot 182 allows the pull wire 142 to be placed within.

(75) FIGS. 24 and 25 show a specialized nut 184 that is configured to thread onto the pull wire tensioner 176. The nut 184 has a slot 186 such that it can be placed over the pull wire 142 and installed onto the pull wire tensioner 176. The assembly of the pull wire tensioner 176 with two oppositely disposed nuts 184 is best seen in FIG. 22. By adjusting the nuts 184 in relation to the pull wire tensioner 176, the tension or slack in the pull wire 142 can be adjusted and optimized.

(76) As shown in FIGS. 17-22, a back plate 188 may capture the valve housing 108 through the use of at least one flexure, or two flexures 190a and 190b as shown. The back plate 188 is designed to accept the valve housing 108 such that it locks into place by allowing the flexures 190 to grip around the curved surface of the valve housing 108. In this way, a user can install all the plumbing lines to the valve housing and then simply press the valve housing onto the back plate 188 to hold it in place. This ease of installment allows for an easier installation and reduces labor time and complications. The back plate 188 may also include fastening holes 192 that allow it to be fastened to the back wall of a cabinet. The back plate 188 may include a pull wire alignment aperture 174 disposed above the middle portion 160 of the pull wire connector 158. The pull wire alignment aperture 174 can be a hole as shown here or a slit, slot or other various sized aperture.

(77) The springs 140 bias the valves 130 to be in the closed position. If for some reason the pull wire 142 is broken or cut, the valves assembly 100 will be closed. This means that at the faucet water will not come out whether or not the faucets are turned and whether or not the foot peddle 54 is depressed. As shown in the differing embodiments of FIGS. 27-29, a lock-on 193 may be included. The lock-on 193 is configured to be placed by the user between the cap 154 and the pull wire connector 158 as shown in FIG. 30 which then forces the two valves 130 into the open position. The faucet may then be used in a traditional manner controlling the flow of water. The lock-on 193 can be inserted by pulling up on the pull wire connector 158. Alternatively, the lock-on 193 may include an acutely-angled insert end 194 that is configured to be wedged between the cap 154 and the valve housing 130 by the user such that the user can simply wedge the lock-on 193 into place. The lock-on 193 also includes a grip 195 such that it can be removed.

(78) When stepping upon the foot peddle 54, it may require a lot of pressure to then open the valves 130. There is a way to use a mechanical advantage to reduce the required foot pressure. Referring now to FIG. 45, the foot peddle 54 may be pivotably connected to the foot peddle bracket 56 about a pivot axis 156. The foot peddle 54 may include a plurality of pull wire connections 197 for the pull wire second end 152 to connect to. As shown, the plurality of pull wire connections 197 are at a varying distance 198 from the pivot axis. When the distance 198 is smaller, this means more pressure is needed to be applied to open the valves. When the distance 198 is larger, this means less pressure is needed to be applied to open the valves. The plurality of pull wire connections 197 can be molded into the various parts of the foot peddle 54 or installed as a separate component that attaches to the foot peddle 54.

(79) Another solution for reducing pressure is shown in FIG. 44. A torque increasing lever 199 may be included, where the torque increasing lever 199 is pivotably attached by a bracket 200 to a structural support or to a second structural support. The pull wire 142 may comprise a first section 142a which is separate from a second section 142b, where the first section 142a comprises the pull wire first end 150 opposite a first lever connection 201. The second section 142b comprises the pull wire second end 152 (not shown in this view) opposite a second lever connection 202. The first and second lever connections are pivotably coupled to the torque increasing lever 199 at a distance apart from one another along the holes 203. In this case, the pull wire first section 142a is closer to the pivot 204 than is the pull wire second section 142b. This means that the force exerted by the pull wire second section 142b is increased along the pull wire first section 142a. In this way, by adjusting the locations of the pull wire 142, increased torque can be achieved which results in a decreased force needed to be exerted at the foot peddle 54.

(80) In an alternative embodiment shown in FIGS. 46 and 47, the generally cylindrical nature of the valve 130 and corresponding valve housing 108 could be shaped into a triangle, square, pentagon, rectangle or many faceted surface, such that it still forms a workable valve assembly 100 as taught herein. For example, if one was to modify the shown structures into a square shape as shown herein, the cylindrically-shaped apertures 110 could be formed into a square-shape that is extended a certain distance. Then the square-shaped aperture 110 would blend into a four-sided pyramid structure 114 that would mimic the functionality of the present invention. The valve 130 could be similarly be shaped to fit within the square-shaped aperture. The seal 136 can then be square-shaped as well. Then, as the valve 130 is moved, it would still create a gradual increase in flow area such that gradual and fine control of the amount of water is still possible by a user foot against the foot peddle 54 which keeps in line with the teachings disclosed herein. Furthermore, the valve's distal end 134 would also be pyramid-shaped to match the inside surface of the pyramid-shaped structure 114. It is understood that these principals could be applied to a wide variety of multi-faceted shapes that incorporate the teachings herein.

(81) FIG. 48 is another embodiment of a foot peddle assembly 102. This embodiment uses the structure shown in FIG. 41, but now has a free-standing foot stand 205. As shown herein, the foot stand 205 can be made from a single piece of cut metal that is then bent into the shape as shown herein. For example, the foot stand has an upright back 206 that allows the bracket 56 to attach to. The foot stand 205 also has a left-side and right-side kick barrier 207 that is used to prevent unintentional activation of the foot peddle assembly. This kick barrier 207 also prevents damage to the mechanisms of the foot peddle. The foot stand can be a free-standing unit that is not bolted or attached to the floor. Alternatively, the foot peddle can be temporarily attached to the floor using hook-and-loop fasteners, adhesives, fasteners or the like.

(82) FIG. 49 shows yet another embodiment of a foot peddle assembly 102. This view is similar to FIG. 48, but now the foot stand 205 fully encloses the foot peddle 54 and the bracket 56 (hidden as shown). As compared to FIG. 48, this embodiment is structurally more rigid and solid. The foot stand 205 can be made from a single sheet of metal that is cut and then bent into shape. The upright back 206 allows the bracket 56 an attachment point. Now the metal is formed to have a ceiling 209 which facilitates a location for the second end 152 of the pull wire 142 to connect to. A weld 208 can be used to fuse and connect the different parts of the metal sheet. This increases the rigidity of the kick barrier sides 207 and also the upright back 206. As compared to FIG. 48, FIG. 49 can use a thinner gauge metal sheet and still result in a stiffer structure. FIGS. 50, 51 and 52 are yet more embodiments of a foot peddle assembly 102. FIG. 52 is a perspective view from the rear such that its structure can be more easily seen and understood. Again, all of these embodiments could be made from a metal sheet which is then bent and welded into position. Alternatively, the foot peddle could be made from plastics, wood, composites and various other materials.

(83) Although several embodiments have been described in detail for purposes of illustration, various modifications may be made to each without departing from the scope and spirit of the invention. Accordingly, the invention is not to be limited, except as by the appended claims.
