The taps of bathroom faucets are usually activated by handles. Currently, handless faucet taps are predominantly located in restrooms of airports among other places. These handless faucet taps serve to significantly reduce the spread of contagious diseases that may have a devastating effect on the well-being of human beings amongst other possibilities. These faucets are not economical for most people and require maintenance by trained technicians for reliable and substantial continual and expected timely operation.
Traditional manually operated faucets in homes are usually fitted with cartridge valves requiring a handle for their activations; consequently, everyone in a home or school or locations where faucets with handles are used is exposed to being infected by handle-enabled faucets. Currently, handle-enabled faucets require that a lever be turned through a right-angle handle for activation, however, the spout is set apart from the handle. This is so because one has to get water running by turning a lever handle through a limited right angle.
Activating the lever can contaminate the lever handle with pathogens. After hands are washed for example, these same hands again are used to activate the lever in order to turn off the flow of water, consequently hands or other parts of the body may again be contaminated by the residual pathogens that initially were left on the lever before hand washing. Current faucets are not designed to wash the lever whenever hands are washed.
Varying designs of manually operated faucet valves exist; however, there is a need for a manually operated faucet enabled with a lever washable cartridge valve. For reasons of economy there is need for a lever washable cartridge faucet that is adaptable to varying designs of cartridge enabled valves. Additionally, such a design of a lever washable cartridge valve should preferably be adaptable to the increasingly creative modern faucet design features.
Additionally, the advent of globalization facilitates the rapid spread of diseases that could significantly impact world health and economies on large scale, wherein such diseases previously were localized and thus did not pose a threat to the global well-being of humanity.
Electronic eye faucet or handle-less faucet are available, e.g., as discussed in Stauffer, U.S. Pat. No. 4,767,922, Chen and U.S. Pat. No. 9,347,207. However, these faucets are not generally affordable by the global population in general and so what is needed is an economically available and reliable faucet that enables washing of the lever arm and thus mitigates the spread of diseases which can quickly become a pandemic and threaten human existence. Additionally, each use of the tap can inherently cause a showering of the lever thus mitigating the spread of pathogens in schools and other institutions and facilities where people share the use of faucets. It is conceivable that there are unknown pathogens and that there will always be the threat of life threatening pathogens at this point of global human development and beyond.
According to an embodiment of the disclosed subject matter, the invention provides greater protection against the transmission of pathogens such as the Covid-19 virus, H1N1 virus, flu virus and other transmittable pathogens and includes preferably a valve cartridge that operates efficiently while providing good flow rates.

A spindle 57 is also part of the cartridge, wherein said upper portion 57 is configured to fit in rotatable relationship with the interior access 34 of lever assembly 600 and the interior access 46 of lever component 602.
Said upper portion 58 of spindle 57 is also enabled with means for attaching and interacting with lever assembly 600. Said portions 58 of upper portion 57 may be serrated for gripping with access 34 of component 600.
Said upper part 56 of spindle 57 are operably configured a with means for allowing neutral motion of said spindle when said handle lever is turned through a pre-determined angle and said component portion 56 of spindle 57 is completely vertically enclosed by circular portion 46 of said lever handle. Thus said portion 56 of spindle 57 is substantially smooth. Said exterior wall portion of 56 may be enabled with means for minimizing friction.
Said lever handle component 46 thus fully encloses portion 56 of said spindle 57 and consequently enables substantially unimpeded relative circular motion of lever component 602 when access slots 34 and 46 are stacked on said spindle as depicted in
Said neutral motion of said spindle may be enabled when said portion 56 of upper portion 57 of spindle said spindle is substantially smooth thus substantially disallowing motion relative motion of said spindle where said such motion restrict motion of said ring portion relative to said spindle.
Said angle of turn of component 38 is designed to rotate a predetermined angle prior to engaging and interacting with component side faces 48 of 32; said predetermined angle of turn of said component 38 is enabled when said lever handle 20 is initiated to turn preferably clockwise thereby enabling flange 52 of lever handle component to turn a predetermined angle prior to engaging face 48 of component 32 and where said portions 58 of spindle 57 is firmly locked in slot 34 of component 200. Such locking means may be enabled by a serrated locking means between spindle portion 58 and interior wall of circular slots 34. Alternatively, such locking may be enabled by rectangular slots. Said turning of lever through a predetermined angle is substantially insignificant in time to initiation of liquid flow from said spout portion 8; said time to initiation of flow of liquid from said spout 8 is directly proportional to the radius and rate of angular displacement; said lever dimension and angular rate of displacement enables time to initiation of flow from spout 8 substantially insignificant.
When said lever handle 20 is turned and said lever handle component flange 52 has turned substantially unopposed through a predetermined angle, said flange 52 may be initiated to contact face 48 of component 32 which in turn enables activation of the spindle 57. Tabs, 60, on the body of the cartridge 604 influences the turning of said lever. Said tabs 60 may define an angular range for the turning of said lever 20 thus when said lever handle 20 is rotated said turning of the lever enables said lever handle is enabled to pass the vertical line of flow 22 from the spout portion 8 of faucet spout 10 and thus enables showering of the said lever 20.

The interior passage 68 of the body 90 defines a longitudinally extending passage 68 through the body, as shown in
The passage 68 preferably has a cylindrical configuration conducive to use of rotating parts therein and can also have one or more sections or ones to accommodate the size and shape of various parts therein. As shown the passage has an upper portion 76 which is preferably of a narrower cross-sectional diameter as shown in
The body further includes at least one side opening 82 extending transversely through the body from the interior passage 68 to the exterior surface of the body 90. The side opening 82 is preferably located to be compatible with traditional faucet design in that water or other fluid flowing upwards through the inlet end 70 of the body into passage 68 would encounter the stationary disk and pass through the opening therein when in the open valve mode until it entered the receiving area of the moveable disk and could then flow out the side opening 82 in the body to continue on to feed the faucet body and outlet of the faucet.
Thus the side opening 82 for this embodiment should preferably be positioned to accommodate that flow in an unimpeded manner within the design. The opening is preferably rectangular for fluid flow characteristics but can have other configuration in order to meet some design or aesthetics. As shown two such side openings 82 are shown which is compatible with the number of openings and receiving areas in the disk cartridge.
The spindle 57 of cartridge 604 has a lower portion 86 which is configured to fit in rotatable relationship with the interior passage 68 of the body 90 when situated within the passage 68 of the said body 90. As shown the lower portion of the spindle sits within the passage and has one or more seals to prevent leakage around the spindle. One O-ring 72 is placed above the lower end portion 86 of the spindle 57, which as shown in this embodiment is somewhat wider than the rest of the spindle and sits within a groove 85 in the lower end portion 86 of the spindle 57, which is situated in the lower portion 78 of the passage 68 of the body 90. The lower end portion of the spindle preferably has such a groove on its exterior surface for receiving a seal such as O-ring capable of providing sealing engagement between the interior surface of the body and the lower end portion of the spindle. The upper end portion of the spindle may preferably have a threaded or other snap-fit, slide in fit, friction fit or gripping surface for attaching the cartridge to a faucet handle so as to be rotatable and function with the handle.

Thus, some feature to allow such rotational interaction with said spindle when said spindle 57 is in turning. As preferred, the bottom surface 96 has a tab or opening therein which can interlock with a matching tab or opening in the moveable disk. A tab 98, preferably rectangular prism in shape fits in a slot 100 in a moveable disk 102 shown in
The moveable disk 102 included within the body in the passage 68 is enabled with means on its upper surface 104 configured to contact and interact with the bottom surface 96 of the lower end portion of the spindle 86 in a rotatable relation. As shown, the upper surface 104 is preferably configured with a slot 100 for receiving a tab 98 therein. The disk upper surface may preferably be defined as a portion of the cross-section of a solid cylinder defined by symmetrically parallel chords shaped to fit within a preferred generally cylindrical portion of the passage 68 in the lower portion 78 in the passage 68. There is preferably two side wall portion 108 defining preferably two fluid receiving area 110 within the moveable disk 102. The receiving area 100 is configured so that when the disk 102 is rotated to align the receiving area 100 with the side opening 82 in the body 68 it will allow fluid flow out of the side opening of the body for feeding the faucet to which to is installed with fluid entering the cartridge from a conduit through the open inlet 70 of the cartridge.
A stationary disk 112 is also included in the design that works with the moveable disk by providing at least one opening 114 extending through the stationary disk 112 for allowing passage of fluid flow from an inlet end 70 of the body 90 entering the passage 68, then through the stationary disk and into the receiving area 110 of the moveable disk, and then out the side opening 82 of the body when the cartridge is in the open position mode. The stationary disk 112 is enabled with a feature 115; the function of feature 115 will subsequently become apparent in this application
Thus when the opening 114 in the stationary disk is aligned with designed so as to fit within faucet handle is turned to reduce and shut off flow; the handle thus initiates the closing of the valve when said handle is initiated to turn in the valve closure turning mode to the off position.
In further embodiments of the invention, an upper surface 130 at the outlet end 74 of the said body 90 may also have means for limiting the rotation of handle 20. or more stops feature. For example preferably two stop feature may be placed on the upper face 130 for limiting rotational movement of the valve cartridge when in use and actuated by a faucet. This helps for smooth faucet use, limited range of motion consistent with disks openings and a desired mating of the various flow openings within a particular predetermined rotational range. As shown in
Said stop features 60 and 61 enabled on said upper surface 130 are arranged such that with the center of a circle lying on the axis of rotation of spindle 57, said stop features location 60 and 61 may characterize end points on separate radii where said radii originate from a common point lying in the plane of surface 130 on the axis of rotation of spindle 57.
Liquid is enabled to flow through portion 8 of spout 10 of faucet assembly depicted in
Said angle of turn of said moveable disk 102 relative to said fixed disk 112 moves simultaneously and in unison with the angle defined by the point of initial activation of face 48 by flange 52 and the point position of stop feature 61 on surface 130 when lever arm 20 is activated to turn in a plane parallel to the plane of surface 130 ; thus enabling positioning of lever arm 20 to intercept the line of flow from spout portion 8 of spout 10. Said rotation of component handle 20 of assembly 600 is designed to be limited by wedges 61. The angle defined by the point of initial activation of face 48 by flange 52 and the point position of stop feature 61 on surface 130 is preferably an obtuse angle.
Thus turn of handle 20 subsequently enable turn of spindle 57 thus enabling opening and closing of valves and thus enables lever handle to be washed by fluid when said faucet is activated for its function. Thus each use of the tap can inherently cause a showering of the lever thus mitigating the spread of pathogens; said inherent showering of the lever 20 is enabled because said lever arm 20 moves through an angle in a horizontal plane that is greater than the angle turned to the said line of flow 22 thus the inherent showering is enabled when the initial angle of turn of the lever to get liquid flowing along line of flow 22 is reversed to enable positioning of lever arm back to a rest positioning in which flow of liquid is disabled.

Said lever handle component 220 depicted in
Tabs, 260, on the body of the cartridge 204 influences the turning of said lever. Said tabs 260 may define an angular range for the turning of said lever 220 thus when said lever handle 220 is rotated said turning of the lever enables said lever handle is enabled to pass the vertical line of flow 27 from the spout portion 15 of faucet spout 17 and thus enables showering of the said lever 220.
As shown in
As shown in
The interior passage 268 of the body 290 defines a longitudinally extending passage through the body as shown in
The passage 268, preferably has a cylindrical configuration conducive to use of rotating parts therein and can also have one or more sections to accommodate the size and shape of various parts therein. As shown the passage has an upper portion 276 which is preferably of a narrower cross-sectional diameter as shown in
The body further includes at least one side opening 282 extending transversely through the body from the interior passage 268 to the exterior surface of the body 90. The side opening 282 is preferably located to be compatible with traditional faucet design in that water or other fluid flowing upwards through the inlet end 270 of the body into passage 268 would encounter the stationary disk and pass through the opening therein when in the open valve mode until it entered the receiving area of the moveable disk and could then flow out the side opening 282 in the body to continue on to feed the faucet body and outlet of the faucet.
Thus the side opening 282 for this embodiment should preferably be positioned to accommodate that flow in an unimpeded manner within the design. The opening is preferably rectangular for fluid flow characteristics but can have other configuration in order to meet some design or aesthetics. As shown two such side openings 282 are shown which is compatible with the number of openings and receiving areas in the disk cartridge.
The spindle 257 of cartridge 204 has a lower portion 286 which is configured to fit in rotatable relationship with the interior passage 268 of the body 290 when situated within the passage 268 of the said body 290. As shown the lower portion of the spindle sits within the passage and has one or more seals to prevent leakage around the spindle. One O-ring 272 is placed above the lower end portion 286 of the spindle 257, which as shown in this embodiment is somewhat wider than the rest of the spindle and sits within a groove 285 in the lower end portion 286 of the spindle 257, which is situated in the lower portion 278 of the passage 268 of the body 290. The lower end portion of the spindle preferably has such a groove on its exterior surface for receiving a seal such as O-ring capable of providing sealing engagement between the interior surface of the body and the lower end portion of the spindle.
The upper end portion of the spindle may preferably have a threaded or other snap-fit, slide in fit, friction fit or gripping surface for attaching the cartridge to a faucet handle so as to be rotatable and function with the handle. The lower end portion 286 of the spindle 257 has a bottom surface 296. The upper end portion 258 of the spindle 257 as shown in
The bottom surface 296 preferably has a feature which allows for interaction with a movable disk so that when the upper portion 258 of the spindle 257 is fitted within a faucet handle assembly 220 depicted in
The rotational movement of the spindle in response to the faucet handle when interconnected and/or interacting with the moveable disk effects opening/closing operation of the cartridge. Thus, some feature to allow such rotational interaction with said spindle when said spindle 257 is in turning. As preferred, the bottom surface 296 has a tab or opening therein which can interlock with a matching tab or opening in the moveable disk. A tab 298, preferably rectangular prism in shape is shown in
The moveable disk 202 included within the body in the passage 268 is enabled with means on its upper surface 204 configured to contact and interact with the bottom surface 296 of the lower end portion of the spindle 286 in a rotatable relation. As shown, the upper surface 204 is preferably configured with a slot 200 for receiving a tab 298 therein. The disk upper surface may preferably be defined as a portion of the cross-section of a solid cylinder defined by symmetrically parallel chords shaped to fit within a preferred generally cylindrical portion of the passage 268 in the lower portion 278 in the passage 268. There is preferably two side wall portion 108 defining preferably two fluid receiving area 210 within the moveable disk 202. The receiving area 200 is configured so that when the disk 202 is rotated to align the receiving area 200 with the side opening 282 in the body 268 it will allow fluid flow out of the side opening of the body for feeding the faucet to which to is installed with fluid entering the cartridge from a conduit through the open inlet 270 of the cartridge.
A stationary disk 212 is also included in the design that works with the moveable disk by providing at least one opening 214 extending through the stationary disk 212 for allowing passage of fluid flow from an inlet end 270 of the body 290 entering the passage 268, then through the stationary disk and into the receiving area 210 of the moveable disk, and then out the side opening 282 of the body when the cartridge is in the open position mode. The stationary disk 212 is enabled with a feature 215; the function of feature 215 will subsequently become apparent in this application.
Thus when the opening 214 in the stationary disk is aligned with designed so as to fit within faucet handle is turned to reduce and shut off flow; the handle thus initiates the closing of the valve when said handle is initiated to turn in the valve closure turning mode to the off position.
In further embodiments of the invention, an upper surface 230 at the outlet end 274 of the said body 290 may also have one or more stops feature. For example at least one raised stop feature may be placed on the upper face 230 for limiting rotational movement of the valve cartridge when in use and actuated by a faucet. This helps for smooth faucet use, limited range of motion consistent with disks openings and a desired mating of the various flow openings within a particular predetermined rotational range. As shown in
Said stop features 260 enabled on a circumference of a circle on said upper surface 230 are arranged such that with the center of said circle, said stop features 260 define with the radius of said circumference, a reflex angle and an obtuse angle. Said center said circle being a point on the axis of rotation of spindle 257 substantially in a plane defined by upper surface 230.
Said stop features 260 enabled on a circumference of a circle on said upper surface 230 enables un-obstructive use of faucet when said lever arm 20 has been turned through preferably through the obtuse angle.
Liquid is enabled to flow through portion 8 of spout 10 of faucet assembly depicted in
Said angle of turn of said moveable disk 202 relative to said fixed disk 212 moves simultaneously in unison through angle defined by the turning of said rotation of component handle 20 but limited by stop feature 260, wherein said angle of turn of lever 20 is defined optimally by a reflex angle and obtuse angle of said wedges 260. Said handle of turn is preferably the obtuse angle defined by the point location of stop feature 260 on the circumference of a circle with enter a geometric point of location of the spindle 257. Thus turn of handle 20 may subsequently enable turn of spindle 257 thus enabling opening and closing of valves and thus enables lever handle to be washed by fluid when said faucet is activated for its function. Thus each use of the tap can inherently cause a showering of the lever thus mitigating the spread of pathogens; said inherent showering of the lever 20 is enabled because said lever arm 20 moves through an angle in a horizontal plane that is greater than the angle turned to the said line of flow 22 thus the inherent showering is enabled when the initial angle of turn of the lever to get liquid flowing along line of flow 22 is reversed to enable positioning of lever arm back to a rest positioning in which flow of liquid is disabled.
