WASHING DEVICE FOR HUMANS AND ANIMALS
Abstract
A washing device [1000] is described which is uniquely adapted
for use by elderly, handicapped, or other users which use one hand
for support and have only one hand free to operate the device.
Since the washing device [1000] is operated with one hand it allows
the user one hand or both hands free to scrub, clean and bathe
animals and humans. The washing device [1000] includes a supply
line [1010] with a cleaning fluid under pressure. The supply line
[1010] directs the fluid to a fluid valve [1210] which is
controlled by a first clicking mechanism 1231 which toggles the
valve between an "open" position directing fluid flow to an
additive valve [1240], and a "closed" position which stops fluid
flow. Additive valve [1240] is also toggled between two positions
by a second clicking mechanism [1232]. In its `fluid only`
position, only fluid is allowed to pass out of the additive valve
[1240] through a mixing chamber [1400] and out of a changeable head
[1700] to the user. In another embodiment, a single three-position
valve performs the same functions. The present invention embodies a
method of one-hand use of the device, or hands free washing using
the device.

Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The present application is a continuation of International
Application PCT/US2008/002195, with an international filing date of
Feb. 20, 2008, which is hereby incorporated by reference as if set
forth in its entirety herein, which is related to or a
continuation-in part of, and claims priority from U.S. Provisional
Patent Application Ser. No. 60/902,226 filed Feb. 20, 2007 which is
hereby incorporated by reference as if set forth in its entirety
herein.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a personal or animal
cleaning product and more specifically to a personal or animal
cleaning product having several optional attachments that can be
operated with one hand. The invention further includes a method of
bathing a human or animal with a washing device that allows for one
handed or hands free soaping, rinsing, and washing.
[0004] 2. Discussion of Related Art
[0005] Typically people use brushes for bathing and showering.
There are brushes which spray water. There are also brushes which
have a reservoir for holding a detergent which is released to more
conveniently aid in cleaning instead of having to lather with soap
then brush.
[0006] These, however have several different designs. One such
design allows a constant detergent flow with the water. This tends
to use the detergent even when not required.
[0007] Another design allows the detergent to be turned on and off,
but requires two hands to operate. Even though functional, it is
difficult to use for those older or disabled people who may need an
arm to balance or hold them up during showering. Letting go of a
support to turn the water on or off is not easy for older or
handicapped people.
[0008] Those who are bathing small children must hold the child at
times while washing them. This is especially true if the child does
not wish to be bathed. This again leaves one arm free for
washing.
[0009] Many people have animals which also require bathing and
scrubbing. The scrubbing product described above works with animals
as well. Since the animal owner typically has to hold the animal
while washing it, they have only one hand available for operating
the scrubbing product. Letting go of the animal typically results
in the animal trying to escape the bath.
[0010] Currently, there is a need for a personal or an animal
scrubbing product which is easy to operate and also may be operated
with a single hand, and may be operated using a mount to provide a
hands free soap shower, allowing both hands to be used to wash the
human or animal.

DETAILED DESCRIPTION OF THE INVENTION
Structure
[0082] FIG. 1 is a perspective view of one embodiment of the
present invention.
[0083] Housing 1100 has a handle section 1120 and a head section
1140. A hose (not shown) is connected to a hose connection 1030 of
the handle section 1120. A fluid, being water in this embodiment,
is supplied to washing device 1000 through hose connection
1030.
[0084] Fluid flows from hose connection 1030 into a valve assembly
1200. Valve assembly 1200 employs at least two valves. The first is
a fluid valve 1210 which either stops the flow of the fluid or
allows the fluid to flow through it to an additive valve 1240, when
a fluid button 1211 is depressed.
[0085] The additive valve 1240 allows the flow of additives, such
as a shampoo or medication to flow only when the additive button
1241 is depressed and fluid is flowing into the additive valve
1240. The additive is held in a refillable container 1600.
Container 1600 is attached to housing 1100 in any number of known
ways, including, but not limited to, a hinged mechanism, a threaded
attachment, a friction fit attachment, attached by snaps, clips or
other known attachment devices.
[0086] The fluid, or the fluid and additive mixture are then
sprayed out of nozzles (not shown) of a head section 1140. This
head section 1140 may have different types and designs of nozzle on
its underside. These nozzles may be adjusted to have different
spray patterns.
[0087] FIG. 2 shows a plan view of the washing device 1000 as
viewed from above with portions of housing 1100 cut-away view to
reveal inner structures. A hose 3 is connected to a hose connection
1030 of the handle section 1120. Water is supplied to washing
device 1000 through hose 3 through hose connection 1030 to a supply
line 1010. Supply line 1010 can be seen inside of washing device
1000 in this view.
[0088] Fluid flows through the supply line 1010 into the valve
assembly 1200. Valve assembly 1200 employs at least two valves. The
first is a fluid valve 1210 which either stops the flow of the
fluid, or allows the fluid to flow through it to an additive valve
1240, when a fluid button 1211 is depressed.
[0089] The additive valve 1240 allows the flow of additives only
when the additive button 1241 is depressed and fluid is flowing
into the additive valve 1240.
[0090] As stated above, the fluid, or the fluid and additive
mixture are then sprayed out of a head section 1140.
[0091] FIG. 3 is a side elevational, cross sectional view of the
washing device 1000. Cleaning fluid from a hose 3 enters through
the hose connection 1030 and passes through the supply line 1010
entering the valve assembly 1200. (Two valves are shown in this
embodiment, however it is understood that any number of additional
valves may be added to this embodiment.)
[0092] The fluid valve 1210 and the additive valve 1240 are
operated by two buttons covered and protected by the flexible
keypad 1500. The fluid button 1211 controls the flow of cleaning
fluid to the additive valve.
[0093] The additive button 1241 controls the flow of additive from
the refillable additive container 1600 to mix with the cleaning
fluid in a mixing chamber 1400 and to create foam. The mixture is
then forced out of nozzle 1710. Optionally a changeable head 1700
is employed which may include a brush, pin brush, sponge,
loofa-type scrubber, cloth, or cloth-like material or other known
grooming devices. The changeable head 1700 may also include a
screen allowing the fluid to pass through it.
[0094] A screen may also be employed at or near the nozzles
1710.
[0095] In this embodiment, the additive and fluid are mixed in a
mixing chamber 1400 before being sprayed out of nozzles 1710.
[0096] In an alternative embodiment, the additive passes through
additive tubes 1713 to or near nozzles 1710. The fluid is also
passed to nozzles 1710. Both are then sprayed out of nozzles
1710.
[0097] In an optional embodiment, an agitator 1300 may be used
which further mixes and foams the mixture. In this embodiment, it
is shown as a rotating wheel 1300 driven by the fluid pressure.
[0098] FIG. 4 is an enlarged view of one embodiment of the valve
assembly 1200. It controls the flow of fluid and additive through
the washing device (1000 of FIGS. 1 and 2). It consists of two
connected chambers, the fluid valve cylinder 1215 and an additive
valve cylinder 1245. Cylinders 1215, 1245 contain seals 1219, 1249
pressing against walls of the cylinder preventing the flow of
liquid past the seals 1219, 1249.
[0099] Fluid button 1211 is connected to fluid valve shaft 1217.
Similarly, additive button 1241 is connected to additive valve
shaft 1247.
[0100] The shafts 1217, 1247 are connected to their respective
seals 1219, 1249. By pressing on the buttons 1211, 1241, it puts
the valve into an "up" or "down" position.
[0101] When fluid button 1211 is pressed, a first clicking
mechanism 1231 toggles between positions to move fluid valve shaft
1217 and fluid valve seal 1219 of fluid valve 1210 alternatively
between the "up" and "down" positions.
[0102] Additionally, a valve stops, 1212, 1242 stop the motion of
the fluid valve seal 1219, and the additive valve seal 1249 at its
maximum upward travel, respectively.
[0103] In an alternative embodiment, there may be stops used to
limit the extent of the travel of seals 1219, 1249 in a downward
direction.
[0104] When additive button 1241 is pressed, a second clicking
mechanism 1232 toggles between positions to move additive valve
shaft 1247 and additive valve seal 1249 of additive valve 1240
alternatively between the "up" and "down" positions. Clicking
mechanisms 1231, 1232 operate in a manner similar to that of a
typical ball point pen.
[0105] Fluid valve 1210 and additive valve 1240 are both shown in
the "up" position.
[0106] With fluid valve 1210 in the `up` position, fluid comes in
from fluid inlet 1010 through fluid inlet 1213, but is trapped
below fluid valve seal 1219, stopping the flow of fluid.
[0107] Since liquid cannot flow past fluid seal 1219, fluid is kept
in the fluid valve cylinder 1215 and not allowed to flow into
additive cylinder 1245.
[0108] At this point it is irrelevant what position additive valve
1240 is in since it directs fluid passing into it.
[0109] FIG. 5 is another enlarged cutaway view of the valves shown
in FIGS. 3 and 4. In FIG. 5, fluid valve 1210 is in the `down`
position, opening a passageway to additive valve 1240. Fluid flows
in the direction marked by arrows "A" and "B".
[0110] Since additive valve 1240 is in the `up` position, fluid
from fluid valve 1210 is allowed to flow into cylinder 1245 down to
seal 1249, but not past it since it makes a fluid-tight seal with
the walls of cylinder 1245. Fluid then exits the valves through
fluid line outlet 1271. Fluid therefore follows the path indicated
by arrow "C".
[0111] In FIG. 6, fluid valve 1210 is in the `down` position
allowing fluid flow into additive valve 1240. Here additive valve
1240 is also in the `down` position, allowing fluid to pass through
additive valve cylinder 1245 and exit by both fluid line outlet
1271 and additive line outlet 1281.
[0112] The fluid flow is therefore as indicated above with
additional flow out of the additive line outlet 1281 as indicated
by arrow "D".
[0113] The fluid passes from fluid line outlet 1271 through fluid
line 1273 and into the mixing chamber (1400 of FIG. 3).
[0114] Additive line outlet 1281 directs the cleaning fluid into a
refillable additive container 1600 through a passageway which is
out of the plane of this sectional view and therefore not shown
here. Additive container 1600 hold any additive intended to be
mixed with the fluid. This may be a detergent, soap, treatment,
medication, solvent or other fluid intended to be mixed with the
fluid.
[0115] The fluid directed into the additive container 1600 through
a container inlet 1610 increases the pressure inside of additive
container 1600 causing the additive to be forced out of a container
outlet 1630 into mixing chamber 1400. Aperture 1630 may be fitted
with a minimal opening force valve which closes when there is no
pressure in additive container 1600 preventing the additive from
leaking out. This valve then opens when there is some degree of
pressure in additive container 1600, allowing the additive to flow
into mixing chamber 1400.
[0116] Referring back to FIG. 3, mixing chamber 1400 may optionally
include an agitator 1300, shown as a wheel here. The wheel is
rotated by the force of the fluid escaping from fluid outlet line
1271. The agitator 1300 operates to mix the fluid with the
additive. It also may operate to agitate the mixture to create foam
for washing.
[0117] FIG. 7 is a perspective view of another embodiment of the
present invention 1000. This embodiment employs a roller valve
assembly 1800. The roller valve assembly 1800 includes a fluid
valve 1810 and an additive valve 1840. This embodiment includes a
similar housing 1100 having a handle section 1120, a head section
1140 and an additive container 1600.
[0118] FIG. 8 is a side elevational view of a cross section of the
washing device 1000 of FIG. 7.
[0119] The parts having the same number in previous figures has the
same function, and need not be repeated here.
[0120] However, the roller valve assembly 1800 replaces the valve
assembly 1200 of the previous embodiment. Fluid from supply line
1010 enters fluid valve inlet 1813. A roller 1815 has a channel cut
through it indicated here in cross section. In its current "closed"
position, no fluid is allowed to pass through fluid valve 1810.
[0121] If tab 1811 is rotated in the direction of arrow "E", its
"open" position, fluid valve inlet 1813 is connected to a fluid
valve outlet 1817 causing fluid to flow through fluid valve 1810,
though fluid valve outlet 1817 into fluid line 1873 and into head
section 1140. In one embodiment, fluid from fluid line 1873 passes
directly out of nozzles 1710.
[0122] In an alternative embodiment, fluid from fluid line 1873
passes into mixing chamber 1400, then out of nozzles 1710.
[0123] An additive valve 1840 has an additive valve inlet 1843
which connects to fluid valve outlet 1817. Additive valve 1840 also
is connected to an additive line 1883. Additive line 1883 leads to
container inlet 1610 of additive container 1600. Additive valve
1840 has a roller 1845 connected to a tab 1841. In the current
"closed" position, as shown, roller 1845 prevents fluid from
additive valve inlet 1843 from flowing to additive line 1883.
[0124] As tab 1841 is rotated in the direction of arrow "F", it
reaches a second or "open" position where fluid from fluid additive
valve inlet 1843 is allowed to flow through additive line 1883 and
into container inlet 1610. This causes pressure forcing additive
out of additive container 1600 through container outlet 1630. In
one embodiment, the additive flows directly out of nozzles 1710
through additive tubes 1713.
[0125] In an alternative embodiment, the additive is passed to a
mixing chamber 1400 to be mixed with the fluid prior to be sprayed
out of nozzles 1710.
[0126] FIG. 9 is a side elevational view of a cross section of
another embodiment of the washing device 1000 according to the
present invention.
[0127] The parts having the same number in previous figures has the
same function, and need not be repeated here.
[0128] In this embodiment, a single three way roller valve 1900
replaces the fluid valve 1810 and additive valve 1840 of the
previous embodiment. Fluid from supply line 1010 enters fluid valve
inlet 1913. A roller 1915 has at least two channels cut through it
indicated here in cross section. In its current "closed" position,
no fluid is allowed to pass through three-way valve assembly
1900.
[0129] In FIG. 10, if tab 1911 is rotated in the direction of arrow
"G" to its "fluid only" position, valve inlet 1913 is connected to
a fluid outlet 1917 causing fluid to flow through three-way roller
valve 1900, through fluid outlet 1917 into fluid line 1873 and into
head section 1140. In one embodiment, fluid from fluid line 1873
passes directly out of nozzles 1710.
[0130] In an alternative embodiment, fluid from fluid line 1873
passes into mixing chamber 1400, then out of nozzles 1710.
[0131] In FIG. 11, tab 1911 of three-way roller valve 1900 may be
rotated further in the direction indicated by arrow "G" to turn the
roller 1915 such that the internal passages line up and connect the
valve inlet 1913 with both the fluid output 1917 and the additive
output 1947. Additive output 1947 is connected to an additive line
1883. Additive line 1883 leads to container inlet 1610 of additive
container 1600.
[0132] This causes pressure forcing additive out of additive
container 1600 through container outlet 1630. In one embodiment,
the additive flows directly out of nozzles 1710 through additive
tubes 1713.
[0133] In an alternative embodiment, the additive is passed to a
mixing chamber 1400 to be mixed with the fluid prior to be sprayed
out of nozzles 1710.
[0134] In alternative embodiments, agitator 1300 may be a series of
flat baffles, or other turbulence creating structures causing
mixing and foaming.
[0135] In still another embodiment, mixing chamber 1400 may include
a small air inlet into mixing chamber preferably in a narrow
section of the fluid flow. By the venture effect, an air inlet near
a fast rushing fluid typically causes a partial vacuum at the air
inlet sucking in air. The air mixes with the fluid creating a
foaming effect. The air inlet may be designed to have an adjustable
opening size and/or have a one way air flow valve allowing air to
flow into the mixing chamber but not out.
[0136] It is understood that the valves described herein may vary
and can be any valve capable of performing the intended function of
allowing, or stopping flow of fluid, allowing the user to select
additive only, select additive and water, and/or a combination
thereof. The valves described herein also allow for varying which
nozzles provide the fluid delivery--said nozzles varying the feel
of the spray. Preferably, the valve is capable of being operated
with one hand while the same hand is holding the washing device, or
the device allows for hands free washing while the device is placed
in a mount.
[0137] Use
[0138] Since the washing device has a thin design, it can easily be
held by the user with one hand. This includes older and handicapped
users. It also includes animal owners using one arm to hold the
animal.
[0139] Both the fluid valve 1210 and the additive valve 1240 are
toggle design valves allowing one-press operation. They do not have
to be continually held to cause fluid flow as do other devices in
the prior art.
[0140] Similarly, the additive valve does not need to be
continually held to cause the flow of additive as do other designs
in the prior art.
[0141] In an additional embodiment of the present invention, it
would be beneficial to employ a larger head section 1140 of FIGS. 1
and 2 to be used on larger animals.
[0142] The invention further includes a method of bathing
comprising the following steps. The washing device described herein
is provided and functionally connected to a water source. A
selectively mountable washing device mount is provided. Said
washing device mount is adaptable to hold the washing device in
place to provide a directed stream of fluid from the washing
device. Said mount being connectable to a wall or water source
pipe, or other static or selectively static object to hold the
mount in place.
[0143] With one hand, a user operates a valve located on the
washing device while holding the washing device [1000].
Alternately, a user operates the valve with one hand while the
washing device [1000] is held by the mount.
[0144] The valve of the washing device [1000] being the valves
discussed herein, which are within the reach or length of a human
thumb and capable of being operated with the thumb of the hand
holding the washing device [1000] while the washing device [1000]
is being held with said hand--without the assistance of an other
hand. Said valves include the three-way roller valve [1900], the
fluid valve [1210], additive valve [1240], and/or the at least one
roller valve located on the back surface within a length of a human
thumb from the handle section [1120].
[0145] At some point during the washing process, (either before
during or after operation of the valve steps(s) washing device is
connected to the mount. When the bathing takes place.
[0146] In one embodiment of the invention, the user operates the
valve as described in the above "operates a valve" step to stop or
start the flow of fluid through the washing device [1000].
[0147] In another embodiment of the invention, the user operates
the valve as described in the above "operates a valve" step to
provide a stream of fluid containing an additive, such as soap from
the washing device [1000].
[0148] In another embodiment of the invention, the user operates
the valve as described in the above "operates a valve" step to
provide a stream of fluid containing no additive (just water) from
the washing device [1000].
[0149] In another embodiment of the invention, the user operates
the valve as described in the above "operates a valve" step to
select among a plurality of settings, which include, flow of fluid,
no flow of fluid, flow of water and flow of water and additive
stream, flow of just water, flow of water and additive stream.
[0150] In another embodiment of the invention, the method includes
the step of washing a human or animal by applying one or more hands
or limbs to the human or animal without holding the washing device
[1000], the washing device [1000] being held by the mount--leaving
both hands free to wash the human or animal. The user reaching with
one hand or limb to operates the valve as described in the above
"operates a valve" step to select among a plurality of settings,
which include, flow of fluid, no flow of fluid, flow of water and
flow of water and additive stream, flow of just water, flow of
water and additive stream.
[0151] An additive such as soap may or may not be placed into the
additive container of the washing device. In the instance no
additive is placed into the additive container, the user may
provide an aerated stream of water by operates the valve as
described in the above "operates a valve" step to direct water
through the additive line output causing an aerated stream to flow
from the washing device [1000].
[0152] In another embodiment of the invention, the washing device
[1000] has at least one nozzle [1710] capable of providing a stream
which is different in feel from the stream of another of the
nozzles [1710] due to the design, shape, size, flow rate, or flow
pattern of the one nozzle [1710]. An example includes a massager
nozzle, or other variations of spray nozzles known in the art. The
user operates the valve as described in the above "operates a
valve" step to select among a plurality of settings, which include,
flow of fluid, no flow of fluid, flow of water and flow of water
and additive stream, flow of just water, flow of water and additive
stream, and any combination of nozzles [1710] capable of providing
a stream which is different in feel from the stream of another of
the nozzles [1710] due to the design, shape, size, flow rate, or
flow pattern of the one nozzle [1710].
[0153] The invention may be used as a hand held or a mounted
adjustable position showerhead for showering or bathing humans or
animals. The invention may be used as a one-handed or NO-handed
soap shower. The invention simplifies the process of someone
bathing himself or herself and/or for a caregiver to use on a human
or animal.
[0154] Using the invention, human beings regain independence in
self-care and bathing where once they had to rely on a caregiver.
Caregivers who once bathed their patients, may now, with the
invention, simply provide "set up" assistance for their client or
patients, i.e. laying out bathing materials required by the client
with no other assistance. In this way the client can be counted as
Independent.
[0155] In-line function controls on the handle allows the user to
control the water from Rinse to Soap to Off and also control the
spray patterns (examples: rain fall and massage, ect.) with the
action of one hand and one thumb. The ease of this control is
designed for those with disabilities or low hand strength and
universal appeal for ease of use for any user.
[0156] Thick handle provides a normal ergonomic and comfortable
grip (Great for those with hand disabilities). Non-slip handle grip
Combined with the thick handle, the non-slip grip provides a more
controlled and comfortable grip while in a wet environment. (Great
for those with or with out hand disabilities). Right or Left handed
user designed in mind for the comfort and control of a right or
left-handed user. Removable and Non-slip grip Reservoir Cap may be
attached and removed with an open palm and short turn for ease of
changing to different bathing soaps or shampoo's while in the wet
environment like a shower or bathtub. The reservoir has a large
window to see the additive and water mixing and spinning inside the
reservoir. Reservoir for Shower Gel, Soap or Shampoo for a favorite
Shower Gel, Shampoo or Soap. This reservoir is built right into the
invention. Remove the reservoir cover and add up to a favorite
Shower Gel or Shampoo or Soap. The invention provides aerated
bathing foam, and a lasting fragrance on the individual and in the
bathroom. The reservoir is self-cleaning.
[0157] Attachments The invention may have many attachments: loofa,
sponge, washcloth, soft exfoliation brush, Pumice stone and finger
sponge for examples. All attachments have a Non-slip grip so it may
be attached and removed with a short turn for the many types of
bathing needs while in the wet environment such as a shower or
bathtub. All attachments are dishwasher safe and the washcloth
cover is clothes washer and dryer safe. The invention also has
optional disposable attachments: loofa, sponge, washcloth, soft
exfoliation brush, Pumice stone and finger sponge for examples.
[0158] Spray Patterns There are many spray patterns controlled buy
a in-line switch and or on the nozzle face it self. One is a
drenching rain-shower spray for a refreshing, invigorating and
energizing rinse and the other is a soothing aerated massaging
spray with two functions. The first function infuses oxygen with
water that gives your body and hair a mind soothing, stress release
and relaxing shower. And the second function is used with your
favorite shower gel, soap or shampoo giving you a sensory pleasing
experience. The oxygen aeration mixed with your favorite shower gel
or shampoo with fragrances will create a great aromatic sensory
pleasing experience during bathing but will also provide a sense of
cleanliness.
[0159] Fill the soap reservoir with your favorite shower gel,
shampoo or soap, move the In-line function control to soap and
attach washing device to the shower mount for a hands free Soap or
Shampoo shower for your body or hair.
[0160] Regular showerhead option Move the washing device in-line
controls on the handle to the different spray functions while
attached or unattached to the adjustable position shower mount or
pluming and use as you would a regular showerhead.
[0161] Height Extension Because of the length of the unit as it
sits in the adjustable position mounting bracket, it will sit
higher then the position of a normal showerhead giving taller
people the extra height needed for them to enjoy a normal shower.
For others, the flexibility to adjust the shower head to the
preferred direction. Allowing one to create many different angles
and directions of the spray. Including the much desired rainfall
effect.
[0162] Therefore, the present invention describes a novel design
which is uniquely adapted to the older user, the handicapped user
and the user which desires to have one hand free, or both hands
free to perform the washing, such as an animal owner.
