- the present invention is directed generally toward plumbing fixtures and more specifically toward bathtub, shower, and basin faucets.
- Various embodiments provide a faucet assembly for installation with a bathtub, shower or washing basin system.
- the most preferred embodiments address safety concerns related to a person falling on the protruding spout by permitting the bathtub spout to rotate away from the faller's trajectory when the spout is impacted by the faller.
- Some embodiments also incorporate the utility of a tub/shower diverter valve so that water flows into the tub or basin when the spout is in one operating position (typically perpendicular to the wall). Then, by rotating the spout to a second operating position (preferably downward and parallel to the wall), water is diverted to the shower head. In the most preferred embodiments, this is accomplished by use of a ball joint installed in the faucet assembly between the water pipe connection and the spout. This ball joint permits access to the water line and allows water to flow through the spout when the spout is positioned perpendicular to the wall. When the spout is rotated, preferably approximately ninety degrees downward, water is diverted from the spout to the shower head. In alternate embodiments the diverter may be activated by rotating the spout in other directions such as up, left, or right.
- the spout may also be used with bathtubs or basins which have no shower head.
- the protruding spout is still dangerous to falling bathers, particularly small children. Therefore the rotating aspect of the device is still attractive as a safety feature.
- the assembly may still be configured to shut off the flow of water to the bathtub completely when rotated approximately ninety degrees from its standard operating position.
- FIG. 1 is a somewhat schematic top view of a faucet assembly 10 installed on a substantially vertical surface 11 .
- FIG. 2 is a somewhat schematic side view of faucet assembly 10 observed at section A-A denoted in FIG. 1 .
- Faucet assembly 10 incorporates a spout 12 that comprises discharge tube 14 and a ball 16 .
- spout 12 is depicted in an “extended position,” meaning that the spout is extended outward from substantially vertical surface 11 .
- FIG. 3 presents a somewhat schematic side view of faucet assembly 10 depicted in an alternate “unextended position.” That is, in FIG. 3 spout 12 has been rotated to a position that is adjacent substantially vertical surface 11 . In this side view, the position of spout 12 is shown to be downwardly directed to this unextended position.
- Discharge tube 14 and ball 16 may be formed from unitary material stock, or may be fabricated separately and joined together as illustrated.
- a receptacle 18 is assembled with a receptacle cover 20 .
- Receptacle 18 may be joined with receptacle cover 20 by such means as adhesives, threaded connections, pressure fitting or similar means that form a substantially leak-tight connection between receptacle 18 and receptacle cover 20 .
- the geometry of receptacle 18 and receptacle cover 20 form a receptacle wall 22 .
- a receptacle cup 24 is formed in part by receptacle wall 22 and in remainder by receptacle 18 .
- Receptacle cup 24 is substantially spherical, and has plurality of geometric axes of rotation that pass through its center. Each axis of rotation is an imaginary line around which a hemi-circular arc of receptacle cup 24 is rotated to define the surface of the receptacle cup 24 . Each axis of rotation passes through the geometric center of the receptacle cup 24 .
- a discharge passage 28 is provided in discharge tube 14 , and a nozzle 30 directs fluid flow out of spout 12 in a direction substantially vertically downward when spout 12 is horizontal.
- a ball bore 32 passes through ball 16 , and ball bore 32 is substantially axially aligned with discharge passage 28 .
- Receptacle 18 comprises a receptacle inlet bore 34 .
- Receptacle inlet bore 34 includes threading 36 at a first end and the second end of receptacle inlet bore 34 terminates in receptacle cup 24 .
- the threading 36 is configured to conform to water pipe thread standards so that faucet assembly 10 may be connected to a pressurized water source (not shown). In alternative embodiments, threading 36 may be replaced with a configuration suitable for brazing, clamping, or other means of attachment to a water supply line.
- slot 38 is cut into wall 22 , and spout 12 passes through slot 38 .
- Slot 38 has a slot first extension limit 40 and a slot second extension limit 42 .
- Slot first extension limit 40 and slot second extension limit 42 conform to the cross section of discharge tube 14 the geometric centers of slot first extension limit 40 and slot second extension limit 42 define the major axis of slot 38 .
- the major axis of slot 38 falls on section line A-A of FIG. 1 .
- the major axis of slot 38 and the center of the receptacle inlet bore 34 establish a single rotational plane through the center of receptacle cup 24 that is perpendicular to a geometric axis of rotation of receptacle cup 24 .
- the rotational plane passes through the second end of the receptacle inlet bore 34 and the rotational plane passes through the major axis of the slot 38 .
- Ball 16 and spout 12 are centered on the rotational plane so that spout 12 may rotate through a range of travel in slot 38 between the position depicted in FIG. 2 that is adjacent the slot first extension limit 40 , to the position depicted in FIG. 3 that is adjacent slot second extension limit 42 .
- an O-ring seal 44 is positioned between ball 16 and receptacle 18 , around receptacle inlet bore 34 and ball bore 32 .
- the geometry of receptacle cup 24 may be configured to push ball 16 against O-ring seal 44 , or in some embodiments a spring may be installed in receptacle cup 4 opposite O-ring seal 44 to provide pressure on O-ring 44 between ball 16 and receptacle 18 to ensure a leak-tight seal.
- ball 16 is sized to fit snugly within receptacle cup 24 , but with sufficient clearance to permit spout 12 to move within its range of travel, and to permit ball 16 to rotate within receptacle cup 24 , with minimal manual forces. Most preferably, ball 16 rotates smoothly within receptacle cup 24 .
- “Smoothly” is a feature wherein the force required to move the spout 12 between any two positions in the range of travel of spout 12 is substantially the same as the force required to move spout 12 between any other two positions in the range of travel of spout 12 .
- a certain amount of “sticktion” i.e., extra force needed at the start of travel
- it may establish a tendency for the spout 12 to remain at any location in its range of travel.
- “sticktion” may be deliberately incorporated in order to induce the spout to remain at one or more designated locations in its range of travel.
- Such “sticktion” may be added deliberately by incorporating spring loaded detents or similar mechanisms which cause the spout 12 to snap set at preferred locations, such as “up” and “down.”
- the apparatus should be designed so that a maximum torque of no more than approximately three to five foot-pounds (approximately a few tenths kilogram-meters) of torque is required to move the spout 12 from a given location to another location within the spout's range of travel, including torque necessary to overcome “sticktion” resistance and resistance from O-ring seal 44 .
- the receptacle inlet bore 34 and the ball bore 32 and the discharge passage 18 are in fluid communication.
- the term “in fluid communication” refers to a configuration of two or more passageways that are structured and positioned so that a fluid may be moved from the start of the first to the end of the last passageway designated as being in fluid communication. That is, when spout 12 is positioned as shown in FIG. 2 , the water supply is turned “on” by using an appropriate fluid pressure differential from the start of the first passageway (receptacle inlet bore 34 ) to the end of last passageway (discharge passage 18 ).
- out of fluid communication refers to a configuration of two or more passageways that obstructed in some manner so that a fluid may not be moved from the start of the first to the end of the last passageway designated as being in fluid communication. That is, when spout 12 is rotated approximately ninety degrees clockwise from the position shown in FIG. 2 to the position shown in FIG.
- the water supply is turned “off” because no reasonable fluid pressure differential across the start of the first passageway to the end of last passageway causes water to flow from the start of the first passageway (receptacle inlet bore 34 ) to the end of last passageway (discharge passage 18 ).
- the terms “appropriate” and “reasonable” pressure are used herein to describe a water pressure that is high enough to establish and maintain water flow though the various passageways configured to conduct water, and that is low enough to avoid blowing out seals or bypassing surfaces that are designed to block the flow of water.
- a faucet assembly may be mounted so that the spout is moved from positions that are not horizontal vs. vertical in order to move the spout from a position adjacent a slot first extension limit to a position adjacent a slot second extension limit.
- FIG. 1 An example is illustrated by viewing FIG. 1 as a side view of faucet assembly 10 and FIG. 2 as a top sectional view of faucet assembly 10 .
- the nozzle is typically rotated ninety degrees to vertical so that fluid discharge is always downward regardless of whether the spout is at a position adjacent a slot first extension limit, or at a position adjacent a slot second extension limit, or anywhere in between.
- the spout may be moved from a horizontal position where the receptacle bore and the ball bore and the discharge tube are in fluid communication to another horizontal position where the receptacle bore and the ball bore and the discharge tube are out of fluid communication.
- the movement of spout still occurs from a position that is adjacent the first extension limit of the slot (where the receptacle bore and the ball bore and the discharge tube are in fluid communication), to a position that is adjacent the second extension limit of the slot (where the receptacle bore and the ball bore and the discharge tube are out of fluid communication).
- the movement of the spout is entirely in a horizontal plane.
- Some embodiments may include both horizontal and vertical movement of the spout.
- the elevation of the spout at the second extension limit of the slot is not higher than the elevation of the spout at the first extension limit of the slot. That is, the position of the spout adjacent the slot second elevation limit is “unelevated” from the position of the spout adjacent the slot first elevation limit.
- the reason that configuration is most preferred is that if the elevation of the spout adjacent the slot second extension limit is higher than the elevation of the spout adjacent the first slot extension limit, the safety aspect of the spout moving away when impacted by a falling person is significantly impaired.

A faucet assembly constructed with a plug and socket arrangement, suitable for use in a bathtub, shower, or basin. The plug may be a ball or cylinder and the socket may be spherical receptacle or a drum. The spout is configured to rotate out of the way when struck by a falling or moving object. A diverter channel may be provided to redirect water flow from the faucet spout to a shower head when the spout is rotated away from a tub filling position.
Description
- This invention relates to the field of faucets for water delivery. More particularly, this invention relates to faucets configured to provide protection from injury as the result of abrupt descent upon the faucet due to slips, trips, falls or other accidents.
- Bathtubs, showers, basins and their plumbing fixtures are common features in homes, schools, sports facilities, clubs and similar establishments. Often bathtubs are combined with a shower create a dual-use shower system for showers and baths. It is widely recognized that many injuries result from falling while taking a shower or bath. These injuries may range from inconsequential to life-threatening. Many precautions are sometimes undertaken to reduce the risk of falling, such as creating a no-slip surface or installing hand rails. Despite these efforts, bathtub injuries remain a serious concern. Small children may also fall while bathing. They often stand up while playing in the bathtub. This increases their risk of falling and injuring themselves.
- A faucet configuration typically incorporates a metal spout that juts from the wall of the bathtub, shower, or basin. Due to its protruding nature, this metal spout is a major safety concern for all users whether they are washing, showering, or bathing. Any fall by a user or abrupt descent of a the head, torso or a limb that collides with this metal spout will almost certainly cause injury.
- In dual-use systems that contain both shower and bath, there is sometimes a diverter valve that is used to change the flow of water between the spout and the shower head. This is often accessed by a valve available to the user. This valve head typically protrudes from the wall or from the spout itself and, like the spout, the valve head is also a safety concern in certain implementations.
- What is needed therefore is an improved configuration of a faucet assembly that better protects users from injuries due to collisions with the faucet or diverter valve head.
- With regard to the above, in one if its embodiments the invention provides a faucet assembly for installation on a substantially vertical surface. The faucet assembly includes a socket having (a) a wall, (b) a cup formed at least in part by the wall, (c) a socket inlet bore having a first end configured for attachment to a water source and a second end that terminates in the cup, and (d) a slot formed in the wall, with the slot having a first extension limit and a second extension limit. A rotatable plug is disposed in the cup, with the rotatable plug having a plug bore and the rotatable plug being sized to fit snugly in the cup. A spout in incorporated, with the spout having a discharge passage that is in fluid communication with the plug bore.

FIG. 7 is a somewhat schematic sectional side view of the faucet assembly ofFIG. 6 , through section B-B ofFIG. 1 . -
FIG. 8 is a somewhat schematic side view of another faucet assembly according to the invention. - The present invention is directed generally toward plumbing fixtures and more specifically toward bathtub, shower, and basin faucets. Various embodiments provide a faucet assembly for installation with a bathtub, shower or washing basin system. The most preferred embodiments address safety concerns related to a person falling on the protruding spout by permitting the bathtub spout to rotate away from the faller's trajectory when the spout is impacted by the faller.
- Some embodiments also incorporate the utility of a tub/shower diverter valve so that water flows into the tub or basin when the spout is in one operating position (typically perpendicular to the wall). Then, by rotating the spout to a second operating position (preferably downward and parallel to the wall), water is diverted to the shower head. In the most preferred embodiments, this is accomplished by use of a ball joint installed in the faucet assembly between the water pipe connection and the spout. This ball joint permits access to the water line and allows water to flow through the spout when the spout is positioned perpendicular to the wall. When the spout is rotated, preferably approximately ninety degrees downward, water is diverted from the spout to the shower head. In alternate embodiments the diverter may be activated by rotating the spout in other directions such as up, left, or right.
- While the preferred embodiment is best applicable to dual use bathtubs with shower heads, the spout may also be used with bathtubs or basins which have no shower head. The protruding spout is still dangerous to falling bathers, particularly small children. Therefore the rotating aspect of the device is still attractive as a safety feature. In such embodiments, the assembly may still be configured to shut off the flow of water to the bathtub completely when rotated approximately ninety degrees from its standard operating position.
- Further understanding of various embodiments may be discerned by a review of the figures.
FIG. 1 is a somewhat schematic top view of afaucet assembly 10 installed on a substantiallyvertical surface 11.FIG. 2 is a somewhat schematic side view offaucet assembly 10 observed at section A-A denoted inFIG. 1 .Faucet assembly 10 incorporates aspout 12 that comprisesdischarge tube 14 and aball 16. InFIG. 1 andFIG. 2 , spout 12 is depicted in an “extended position,” meaning that the spout is extended outward from substantiallyvertical surface 11.FIG. 3 presents a somewhat schematic side view offaucet assembly 10 depicted in an alternate “unextended position.” That is, inFIG. 3 spout 12 has been rotated to a position that is adjacent substantiallyvertical surface 11. In this side view, the position ofspout 12 is shown to be downwardly directed to this unextended position. -
Discharge tube 14 andball 16 may be formed from unitary material stock, or may be fabricated separately and joined together as illustrated. Areceptacle 18 is assembled with areceptacle cover 20.Receptacle 18 may be joined withreceptacle cover 20 by such means as adhesives, threaded connections, pressure fitting or similar means that form a substantially leak-tight connection betweenreceptacle 18 andreceptacle cover 20. The geometry ofreceptacle 18 and receptacle cover 20 form areceptacle wall 22. Areceptacle cup 24 is formed in part byreceptacle wall 22 and in remainder byreceptacle 18.Receptacle cup 24 is substantially spherical, and has plurality of geometric axes of rotation that pass through its center. Each axis of rotation is an imaginary line around which a hemi-circular arc ofreceptacle cup 24 is rotated to define the surface of thereceptacle cup 24. Each axis of rotation passes through the geometric center of thereceptacle cup 24. - A
discharge passage 28 is provided indischarge tube 14, and anozzle 30 directs fluid flow out ofspout 12 in a direction substantially vertically downward whenspout 12 is horizontal. A ball bore 32 passes throughball 16, and ball bore 32 is substantially axially aligned withdischarge passage 28.Receptacle 18 comprises a receptacle inlet bore 34. Receptacle inlet bore 34 includes threading 36 at a first end and the second end of receptacle inlet bore 34 terminates inreceptacle cup 24. The threading 36 is configured to conform to water pipe thread standards so thatfaucet assembly 10 may be connected to a pressurized water source (not shown). In alternative embodiments, threading 36 may be replaced with a configuration suitable for brazing, clamping, or other means of attachment to a water supply line. - In the embodiment of
FIGS. 1, 2 , and 3 aslot 38 is cut intowall 22, and spout 12 passes throughslot 38.Slot 38 has a slotfirst extension limit 40 and a slotsecond extension limit 42. Slotfirst extension limit 40 and slotsecond extension limit 42 conform to the cross section ofdischarge tube 14 the geometric centers of slotfirst extension limit 40 and slotsecond extension limit 42 define the major axis ofslot 38. In the embodiment shown inFIGS. 1, 2 , and 3, the major axis ofslot 38 falls on section line A-A ofFIG. 1 . The major axis ofslot 38 and the center of the receptacle inlet bore 34 establish a single rotational plane through the center ofreceptacle cup 24 that is perpendicular to a geometric axis of rotation ofreceptacle cup 24. The rotational plane passes through the second end of the receptacle inlet bore 34 and the rotational plane passes through the major axis of theslot 38.Ball 16 and spout 12 are centered on the rotational plane so thatspout 12 may rotate through a range of travel inslot 38 between the position depicted inFIG. 2 that is adjacent the slotfirst extension limit 40, to the position depicted inFIG. 3 that is adjacent slotsecond extension limit 42. - As depicted in
FIGS. 1, 2 , and 3, an O-ring seal 44 is positioned betweenball 16 andreceptacle 18, around receptacle inlet bore 34 and ball bore 32. The geometry ofreceptacle cup 24 may be configured to pushball 16 against O-ring seal 44, or in some embodiments a spring may be installed in receptacle cup 4 opposite O-ring seal 44 to provide pressure on O-ring 44 betweenball 16 andreceptacle 18 to ensure a leak-tight seal. - Preferably,
ball 16 is sized to fit snugly withinreceptacle cup 24, but with sufficient clearance to permitspout 12 to move within its range of travel, and to permitball 16 to rotate withinreceptacle cup 24, with minimal manual forces. Most preferably,ball 16 rotates smoothly withinreceptacle cup 24. “Smoothly” is a feature wherein the force required to move thespout 12 between any two positions in the range of travel ofspout 12 is substantially the same as the force required to movespout 12 between any other two positions in the range of travel ofspout 12. However, in some embodiments a certain amount of “sticktion” (i.e., extra force needed at the start of travel) may exist naturally, and it may establish a tendency for thespout 12 to remain at any location in its range of travel. In some embodiments “sticktion” may be deliberately incorporated in order to induce the spout to remain at one or more designated locations in its range of travel. Such “sticktion” may be added deliberately by incorporating spring loaded detents or similar mechanisms which cause thespout 12 to snap set at preferred locations, such as “up” and “down.” Preferably, the apparatus should be designed so that a maximum torque of no more than approximately three to five foot-pounds (approximately a few tenths kilogram-meters) of torque is required to move thespout 12 from a given location to another location within the spout's range of travel, including torque necessary to overcome “sticktion” resistance and resistance from O-ring seal 44. - Note that when, as depicted in
FIG. 2 , spout 12 is positioned adjacent thefirst extension limit 40 of theslot 38, the receptacle inlet bore 34 and the ball bore 32 and thedischarge passage 18 are in fluid communication. The term “in fluid communication” refers to a configuration of two or more passageways that are structured and positioned so that a fluid may be moved from the start of the first to the end of the last passageway designated as being in fluid communication. That is, whenspout 12 is positioned as shown inFIG. 2 , the water supply is turned “on” by using an appropriate fluid pressure differential from the start of the first passageway (receptacle inlet bore 34) to the end of last passageway (discharge passage 18). - When, as depicted in
FIG. 3 , spout 12 is positioned adjacent thesecond extension limit 42 of theslot 38, the receptacle bore 34 and the ball bore 32 and thedischarge tube 14 are out of fluid communication. The term “out of fluid communication” refers to a configuration of two or more passageways that obstructed in some manner so that a fluid may not be moved from the start of the first to the end of the last passageway designated as being in fluid communication. That is, whenspout 12 is rotated approximately ninety degrees clockwise from the position shown inFIG. 2 to the position shown inFIG. 3 , the water supply is turned “off” because no reasonable fluid pressure differential across the start of the first passageway to the end of last passageway causes water to flow from the start of the first passageway (receptacle inlet bore 34) to the end of last passageway (discharge passage 18). - As used herein, the terms “appropriate” and “reasonable” pressure are used herein to describe a water pressure that is high enough to establish and maintain water flow though the various passageways configured to conduct water, and that is low enough to avoid blowing out seals or bypassing surfaces that are designed to block the flow of water.
- In some embodiments a faucet assembly may be mounted so that the spout is moved from positions that are not horizontal vs. vertical in order to move the spout from a position adjacent a slot first extension limit to a position adjacent a slot second extension limit. An example is illustrated by viewing
FIG. 1 as a side view offaucet assembly 10 andFIG. 2 as a top sectional view offaucet assembly 10. Note that in such embodiments, the nozzle is typically rotated ninety degrees to vertical so that fluid discharge is always downward regardless of whether the spout is at a position adjacent a slot first extension limit, or at a position adjacent a slot second extension limit, or anywhere in between. In such an embodiment the spout may be moved from a horizontal position where the receptacle bore and the ball bore and the discharge tube are in fluid communication to another horizontal position where the receptacle bore and the ball bore and the discharge tube are out of fluid communication. In such embodiments, the movement of spout still occurs from a position that is adjacent the first extension limit of the slot (where the receptacle bore and the ball bore and the discharge tube are in fluid communication), to a position that is adjacent the second extension limit of the slot (where the receptacle bore and the ball bore and the discharge tube are out of fluid communication). However, in such embodiments, the movement of the spout is entirely in a horizontal plane. Some embodiments may include both horizontal and vertical movement of the spout. But, in the most preferred embodiments the elevation of the spout at the second extension limit of the slot is not higher than the elevation of the spout at the first extension limit of the slot. That is, the position of the spout adjacent the slot second elevation limit is “unelevated” from the position of the spout adjacent the slot first elevation limit. The reason that configuration is most preferred is that if the elevation of the spout adjacent the slot second extension limit is higher than the elevation of the spout adjacent the first slot extension limit, the safety aspect of the spout moving away when impacted by a falling person is significantly impaired. -
FIG. 4 illustrates an aspect of some embodiments. A side view offaucet assembly 50 is illustrated, installed on substantially vertical surface 51.Faucet assembly 50 has aspout 52 that is comprised of adischarge tube 54 and aball 56.Spout 52 is shown upwardly directed in an extended position, at aninclination angle 53 of about 25°. The inclination angle is referenced from substantially horizontal plane 55 that is orthogonal to substantially vertical surface 51. -
Discharge tube 54 andball 56 may be fabricated from a single piece of material stock, or may be fabricated separately and joined by welding, brazing, or other bonding mechanisms, ordischarge tube 54 andball 56 may be joined together by mating threads. Areceptacle 58 is assembled with areceptacle cover 60. Receptacle cover andreceptacle 58 form awall 62.Wall 62 andreceptacle 58 establish a receptacle cup 64. In the embodiment shown, receptacle cup 64 is substantially spherical, and has a plurality of axes of rotation each passing through the geometric center of receptacle cup 64.Ball 56 is sized to fit snugly but easily manually rotatable within receptacle cup 64, including the force necessary to overcome resistance to rotation due to o-ring seal 84. - A
discharge passage 68 and anozzle 70 are formed indischarge tube 54. A ball bore 72 formed inball 56 is in fluid communication withdischarge passage 68. A receptacle inlet bore 74 is formed inreceptacle 58, and receptacle inlet bore 74 has a threadedsection 76 for attachment offaucet assembly 50 to a water supply line (not shown). - A
slot 78 is formed inwall 62. The minor axis (width) ofslot 78 is sized to permitspout 52 to fit loosely withinslot 78.Slot 78 has a slotfirst extension limit 80 and a slotsecond extension limit 82. In the embodiment ofFIG. 4 first extension limit 80 andsecond extension limit 82 are configured to permitspout 52 to be positioned over a range of travel that exceed ninety degrees. A bore extension 86 has been formed inball 56 to ensure fluid communication between receptacle inlet bore 74 and ball bore 72 whenspout 52 is positioned as illustrated inFIG. 4 . - In embodiments of
faucet assembly 50 as depicted inFIG. 4 , slotfirst extension limit 80 may be positioned to permitspout 52 to rotate one hundred and eighty degrees (or even at a reflex angle) from slotsecond extension limit 82. However, in embodiments offaucet assembly 50 whereslot 78 is positioned to be vertical (as plumb), it is preferred that slotfirst extension limit 80 not permitspout 52 to be positioned at an inclination angle of more than approximately forty-five degrees above horizontal. Ifspout 52 is positioned at an inclination angle of more than approximately forty-five degrees above horizontal it may not rotate vertically downward if impacted by a person falling on or impactingspout 52. -
FIG. 5 illustrates a side view of an embodiment wherein movement of a spout causes a diversion of water from the spout to a second passageway.Faucet assembly 90 is installed on a substantiallyvertical surface 91, and has aspout 92 that comprises adischarge tube 94 and aball 96. InFIG. 5 , spout 92 is depicted in a downwardly directed unextended position, Areceptacle 98 is provided which is assembled withreceptacle cover 100.Receptacle cover 100 and a portion ofreceptacle 98 establish a receptacle wall 102, and which together withreceptacle 98 form a substantiallyspherical receptacle cup 104.Ball 96 fits snugly intoreceptacle cup 104. A discharge passage 108 and anozzle 110 are formed inspout 92. - Ball bore 112 is formed in
ball 56 and is in fluid communication with discharge passage 108. Receptacle inlet bore 114 inreceptacle 98 is fitted with inlet threading 116 for attachment to a water supply line. - A
slot 118 is formed in receptacle wall 102;slot 118 has a firstslot extension limit 120 and a secondslot extension limit 122. Whenspout 92 is rotated approximately ninety degrees counterclockwise from the position depicted inFIG. 5 , receptacle inlet bore 114 and ball bore 112 are in fluid communication. However, in the position illustrated inFIG. 5 , ball bore 112 is out of fluid communication with receptacle inlet bore 116 due to the configuration ofball 96 andinlet seal 132 anddiversion seal 134. That is, water under reasonable pressure in receptacle inlet bore 114 cannot reach and flow through ball bore 112 whenspout 92 is in the position illustrated inFIG. 5 . -
Ball 96 also includes diversion passage 126, andreceptacle 98 includes receptacle outlet bore 128. Outlet threading 120 is formed as shown in outlet bore 128. Both inlet threading 116 and outlet threading 120 may be replaced with other elements for attachingfaucet assembly 90 to water lines. Whenspout 92 is positioned as illustrated inFIG. 5 , receptacle inlet bore 114, diversion passage 126 and receptacle outlet bore 128 are in fluid communication. That is, water under reasonable pressure in receptacle inlet bore 114 will flow through receptacle inlet bore 114 through diversion passage 126 and out receptacle outlet bore 130 whenspout 92 is in the position illustrated inFIG. 5 . - The embodiment shown in
FIG. 5 is useful in applications where it is desirable to divert water flow from one output alternative to another output alternative. For example, the configuration ofFIG. 5 may be used to provide water to a tub or basis whenspout 92 is rotated approximately ninety degrees counterclockwise, and use to provide water to a shower head (connected through outlet threading 130) whenspout 92 is positioned as illustrated inFIG. 5 . - FIGS. 6 illustrates a top view and 7 illustrates a side view of another embodiment.
