Description
FIELD
[0001] 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.
BACKGROUND
[0002] 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.
[0003] 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.
[0004] 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.
[0005] 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.
SUMMARY

the second extension limit of the slot is downwardly directed to
the unextended position. The socket bore and the plug bore are in
fluid communication when the spout is positioned adjacent the first
extension limit of the slot and the socket bore and the plug bore
are out of fluid communication when the spout is positioned
adjacent the second extension limit of the slot.

DETAILED DESCRIPTION
[0018] 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.
[0019] 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.
[0020] 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.
[0021] Further understanding of various embodiments may be
discerned by a review of the figures. 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. In FIG. 1 and FIG. 2, 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.
[0022] 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.
[0023] 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.
[0024] In the embodiment of FIGS. 1, 2, and 3 a 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. In the embodiment shown in FIGS.
1, 2, and 3, 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.
[0025] As depicted in FIGS. 1, 2, and 3, 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.
[0026] Preferably, 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. 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 the spout 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 the spout 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 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.
[0027] Note that when, as depicted in FIG. 2, spout 12 is
positioned adjacent the first extension limit 40 of the slot 38,
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).
[0028] When, as depicted in FIG. 3, spout 12 is positioned adjacent
the second extension limit 42 of the slot 38, the receptacle bore
34 and the ball bore 32 and the discharge 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, when spout 12 is rotated approximately
ninety degrees clockwise from the position shown in FIG. 2 to the
position shown in FIG. 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).
[0029] 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.
[0030] 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 of faucet assembly 10 and FIG. 2 as a top sectional view
of faucet 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.
[0031] FIG. 4 illustrates an aspect of some embodiments. A side
view of faucet assembly 50 is illustrated, installed on
substantially vertical surface 51. Faucet assembly 50 has a spout
52 that is comprised of a discharge tube 54 and a ball 56. Spout 52
is shown upwardly directed in an extended position, at an
inclination angle 53 of about 25.degree.. The inclination angle is
referenced from substantially horizontal plane 55 that is
orthogonal to substantially vertical surface 51.
[0032] Discharge tube 54 and ball 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, or
discharge tube 54 and ball 56 may be joined together by mating
threads. A receptacle 58 is assembled with a receptacle cover 60.
Receptacle cover and receptacle 58 form a wall 62. Wall 62 and
receptacle 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.
[0033] A discharge passage 68 and a nozzle 70 are formed in
discharge tube 54. A ball bore 72 formed in ball 56 is in fluid
communication with discharge passage 68. A receptacle inlet bore 74
is formed in receptacle 58, and receptacle inlet bore 74 has a
threaded section 76 for attachment of faucet assembly 50 to a water
supply line (not shown).
[0034] A slot 78 is formed in wall 62. The minor axis (width) of
slot 78 is sized to permit spout 52 to fit loosely within slot 78.
Slot 78 has a slot first extension limit 80 and a slot second
extension limit 82. In the embodiment of FIG. 4 first extension
limit 80 and second extension limit 82 are configured to permit
spout 52 to be positioned over a range of travel that exceed ninety
degrees. A bore extension 86 has been formed in ball 56 to ensure
fluid communication between receptacle inlet bore 74 and ball bore
72 when spout 52 is positioned as illustrated in FIG. 4.
[0035] In embodiments of faucet assembly 50 as depicted in FIG. 4,
slot first extension limit 80 may be positioned to permit spout 52
to rotate one hundred and eighty degrees (or even at a reflex
angle) from slot second extension limit 82. However, in embodiments
of faucet assembly 50 where slot 78 is positioned to be vertical
(as plumb), it is preferred that slot first extension limit 80 not
permit spout 52 to be positioned at an inclination angle of more
than approximately forty-five degrees above horizontal. If spout 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 impacting spout
52.
[0036] 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
substantially vertical surface 91, and has a spout 92 that
comprises a discharge tube 94 and a ball 96. In FIG. 5, spout 92 is
depicted in a downwardly directed unextended position, A receptacle
98 is provided which is assembled with receptacle cover 100.
Receptacle cover 100 and a portion of receptacle 98 establish a
receptacle wall 102, and which together with receptacle 98 form a
substantially spherical receptacle cup 104. Ball 96 fits snugly
into receptacle cup 104. A discharge passage 108 and a nozzle 110
are formed in spout 92.
[0037] Ball bore 112 is formed in ball 56 and is in fluid
communication with discharge passage 108. Receptacle inlet bore 114
in receptacle 98 is fitted with inlet threading 116 for attachment
to a water supply line.
[0038] A slot 118 is formed in receptacle wall 102; slot 118 has a
first slot extension limit 120 and a second slot extension limit
122. When spout 92 is rotated approximately ninety degrees
counterclockwise from the position depicted in FIG. 5, receptacle
inlet bore 114 and ball bore 112 are in fluid communication.
However, in the position illustrated in FIG. 5, ball bore 112 is
out of fluid communication with receptacle inlet bore 116 due to
the configuration of ball 96 and inlet seal 132 and diversion seal
134. That is, water under reasonable pressure in receptacle inlet
bore 114 cannot reach and flow through ball bore 112 when spout 92
is in the position illustrated in FIG. 5.
[0039] Ball 96 also includes diversion passage 126, and receptacle
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
attaching faucet assembly 90 to water lines. When spout 92 is
positioned as illustrated in FIG. 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 when spout 92 is in the position illustrated in FIG. 5.
[0040] 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 of FIG. 5 may be used to provide water to a tub or
basis when spout 92 is rotated approximately ninety degrees
counterclockwise, and use to provide water to a shower head
(connected through outlet threading 130) when spout 92 is
positioned as illustrated in FIG. 5.
[0041] FIGS. 6 illustrates a top view and 7 illustrates a side view
of another embodiment. Faucet assembly 140 is installed on
substantially vertical surface 141, and has a spout tube 142 that
is attached to cylinder 146. As the name suggests, cylinder 146 is
cylindrical, and cylinder 146 has a single axis of rotation that is
an imaginary line through the centers of the circles that form the
end of the cylinder. Cylinder 146 is fitted snugly within drum 148.
Drum 148 is also cylindrical and has a single axis of rotation that
is congruent with the axis of rotation of cylinder 146. A portion
of drum 148 forms drum wall 152, and drum cup 154 is formed in part
by drum wall 152 and drum 148.
[0042] A discharge passage 158 and nozzle 160 are formed in spout
tube 142. A cylinder bore 162 is formed in cylinder 146 and a drum
inlet bore 162 is formed in drum 148. Water supply pipe threading
166 is provided for drum inlet bore 164. A slot 168 is provided in
drum wall 152, and slot 168 has a slot first extension limit 170
and a second slot extension limit 172. The centers of slot first
extension limit 170 and second slot extension limit 172 define the
major axis of slot 168. Spout tube 142 has external spout threads
174 that mate with internal cylinder threads 176 formed in cylinder
bore 162. An axial seal 178 is formed by an O-ring positioned in a
circular slot formed in the section of drum cup 154 around drum
inlet bore 148. First axial radial seal 180 and second radial seal
182 are positioned in circular grooves cut into cylinder 146. In
preferred embodiments, faucet assembly 140 is assembled by (1)
positioning axial seal 178 in drum cup 154, (2) positioning first
radial seal 180 and second radial seal 182 on cylinder 146, (3)
sliding drum 136 into drum cup 154 so that cylinder threads 176 are
accessible through slot 176, and (4) attaching spout tube 142 to
cylinder 146 by screwing pout threads 174 into cylinder threads
176.
[0043] The "balls" and "cylinder" described previously in various
embodiments are examples of "plugs" according to the invention. The
"receptacles" and "drums" described previously in various
embodiments are examples of "sockets" according to the
invention.
[0044] FIG. 8 illustrates an embodiment where the movement of the
spout does not turn off the water supply from the faucet assembly.
Faucet assembly 190 is mounted on substantially vertical surface
191 and has a spout tube 192 that is attached to plug 196. Socket
198 has a socket wall 202 that, together with a portion of socket
198, forms a socket cup 204. A discharge passage and nozzle 210 are
formed in spout tube 192.
[0045] A plug bore 212 is formed in plug 196 and a socket inlet
bore 214 is formed in socket 198. Attachment threading 216 is
provided at the end of socket inlet bore 214. A slot 218 is formed
in socket wall 202. Slot 218 has a slot first extension limit 220
and a slot second extension limit 222. Spout threads 224 on spout
tube 192 are used to attach spout tube 192 to plug threads 226 in
plug 196. An axial seal 228 is provided as shown between socket cup
204 and plug 196. When spout tube 192 is in the position
illustrated in FIG. 8, socket inlet bore 214, plug bore 212,
discharge passage 208, and nozzle 210 are in fluid communication. A
bore expansion 236 is provided in plug 196 so that when spout tube
192 is rotated approximately ninety degrees clockwise from the
position illustrated in FIG. 8, socket inlet bore 214, plug bore
212, discharge passage 208, and nozzle 210 are still in fluid
communication. Thus, in the embodiment of FIG. 8, the rotation of
spout tube 192 provides such functions as diverting the water
stream for convenience and deflecting the spout as it is hit by a
falling person to avoid injury, without turning off the water.
