Description
FIELD OF THE INVENTION
[0001] The present invention relates to brushes and more
specifically to fluid dispensing brushes that can be used with
storage devices.
BACKGROUND OF THE INVENTION
[0002] Hand held cleaning brushes can define reservoirs in their
handles for the dispensing of a fluid to assist in the cleaning or
disinfecting of a surface. The handles of the brushes have a
resealable port for filling the reservoir and the opposed end of
the brush has through holes for the dispensing of the fluid from
the reservoir. Cleaning brush for toilet bowls can be especially
aided by the dispensing of a fluid directly from the brush that is
then used to scrub the area where the fluid has been applied.
[0003] Cleaning devices dispense fluids from the reservoir in the
handle using manually applied pressure or gravity. Devices that
apply pressure manually can have the disadvantage that the
application of too much pressure causes the cleaning liquid to
splatter over the undesirable areas in the bathroom and the user.
Devices that use gravity are often limited in their application by
the bristles of the cleaning head that undesirably limit the direct
application of the cleaning liquid independent of the bristles.
[0004] A hand held cleaning device is needed that dispenses a
stream of fluid from an internal reservoir of the brush at a
controlled rate and direction for cleaning.
SUMMARY OF THE INVENTION
[0005] A fluid dispensing toilet brush apparatus is disclosed that
comprises a handle that has a wall that defines a reservoir. The
handle includes a proximal end portion and a distal end portion
that define a longitudinal axis. The handle includes a first
sealable aperture in the wall that is in fluid communication with
the reservoir and a second sealable aperture in the wall of the
distal end portion.
[0006] An actuation mechanism is connected to the handle that
includes a movable switch and a rod. The switch is fixedly
connected to a proximal end portion of the rod and a valve is
connected to the distal end portion of the rod. The rod extends
through the second aperture and the valve opens and seals the
second aperture. The actuation mechanism is biased to seal the
second aperture.
[0007] A brush head is connected to the distal end portion of the
handle. The brush head has a wall that defines a tube that has a
distal aperture and a proximal aperture that are in fluid
communication with the valve. The brush head includes a plurality
of bristles connected to the wall.
[0008] The brush of the fluid dispensing toilet brush apparatus has
a first position wherein the first aperture and the second aperture
are sealed and a second position wherein the switch is moved to
open the second aperture and the reservoir is in fluid
communication with the distal aperture of the brush head.
[0009] The actuation mechanism preferably includes a housing and a
bias member. The housing is positioned in the reservoir and sealed
from the reservoir. The bias member urges the switch to the first
position.
[0010] The rod in the vicinity of the second aperture has a
cross-sectional area perpendicular to the longitudinal axis that
changes and the flow through the second aperture varies with the
change in the cross-sectional area. The reservoir can include a
fluid and gravity forces the fluid from the reservoir through the
distal aperture. The flow of the fluid from the second aperture is
interrupted by the valve. An inside surface of the wall of the
brush head receives the interrupted fluid flow from the valve and
provides a stream of fluid flow from the distal aperture. The force
of gravity on the fluid in the brush can be augmented by at least
one disk connected to the rod in the reservoir.
[0011] The actuation mechanism includes a housing that connects to
the grip and at least partially extends into the reservoir. The
housing is sealed from the reservoir. The switch connects to an arm
that extends into the housing and the arm connects to the proximal
end of the rod.
[0012] The handle includes a flange and a tubular wall portion can
enclose a volume that is in fluid communication with the reservoir.
The brush can include a storage device. The handle preferably
includes a flange and the storage device receives at least the
distal end portion of the brush and interfaces with the flange.
[0013] A toilet brush and storage device that comprises a brush
that has a proximal end portion and a distal end portion that
define a longitudinal axis. The proximal end portion includes a
handle and the distal end portion includes a brush head. The handle
has a grip and the brush head has a plurality of bristles.
[0014] A storage device that receives a distal end portion of the
brush in a storage position. The storage device comprises a first
tubular wall of the storage device that has an upper edge and a
lower edge. The upper edge connects to a rim and the inner edge of
the rim connects to a downwardly depending tubular extension that
has a free terminal end. The rim and extension define an aperture
that receives at least the distal end portion of the brush.
[0015] A second tubular wall of the storage device has an upper
free end and a lower end that connect to a bottom. The upper free
end is removably positionable between the first tubular wall and
the downwardly depending tubular extension. The second tubular wall
is adapted to include a decorative material. The second tubular
wall is at least partially visible through the first tubular
wall.
[0016] The brush includes a flange that abuts the rim and limits
the downward positioning of the brush in the storage position. The
flange includes a distally extending tubular portion that is
received by the downwardly depending tubular extension from the rim
in the storage position. The flange and the rim are preferably
approximately perpendicular to the longitudinal axis.
[0017] An outer surface of the second tubular wall of the storage
device includes a decorative material that is visible through the
first tubular wall. The outer surface of the second tubular wall of
the storage device can also be adapted to receive a removable piece
of decorative material that is visible through the first tubular
wall.
[0018] The second tube of the storage device has a diameter that is
tapered from the free end to the bottom. The first tube and the
second tube have a cylindrical outer shape and are concentrically
positioned by the base.
[0019] The handle of the brush includes a wall that defines a
reservoir. The handle has a proximal end portion that defines a
grip and a first sealable aperture is defined in the wall that is
in fluid communication with the reservoir. A second sealable
aperture is defined in the wall of a distal end portion of the
handle. A distal aperture is defined in the wall of the brush head
that is in fluid communication with the second aperture. An
actuation mechanism is connected to the handle that selectively
opens and seals the second aperture.

DETAILED DESCRIPTION
[0025] Referring to FIG. 1, the preferred embodiment of a fluid
dispensing brush apparatus 10 includes a brush 12 that has a
proximal end portion 14 and a distal end portion 16 that define a
longitudinal axis-X. Apparatus 10 can also include a storage device
or container 18 that is an elongate receptacle for brush 12 that
defines a longitudinal axis-X'. Brush 12 is in a storage position
when axes X and X' are approximately aligned and brush 12 is
positioned in storage device 18.
[0026] As shown in FIG. 2, a handle 20 of brush 12 includes a wall
22 that preferably has an elongate tubular shape that defines an
interior reservoir 23. Handle 20 has a proximal end portion that
includes a grip 24, an aperture 25, and a cap 26. Grip 24 is
configured for grasping by a single hand. Aperture 25 is in fluid
communication with reservoir 23. Cap 26 is shown in a closed and
scaled position and provides access to and a fluid tight seal of
aperture 25. Cap 26 and handle 20 are shown as having a threaded
connection that includes an O-ring type seal 26a, but the interface
can be any type of connector that provides a fluid tight seal such
as a snap or friction fit mechanism, for example. A distal end
portion of handle 20 defines an aperture 28 in wall 22 that is in
fluid communication with reservoir 23. Brush 12 is preferably made
of rigid polymer materials, but it can include composite, metal,
glass, elastomer and flexible polymer materials.
[0027] As shown in FIGS. 1 and 2, handle 20 preferably includes a
disk shaped cross guard or flange 28 approximately perpendicular to
the longitudinal axis that extends outwardly from wall 22. Flange
28 has a flat distal surface, opposed flat proximal surface and an
outer edge. Flange 28 includes a tubular wall portion 29 that is
approximately parallel to the longitudinal axis and extends
distally from the distal surface of flange 28. The outer edge of
flange 28 preferably extends a predetermined distance outward from
tubular wall portion 29 to define a lip. Flange 28 and tubular wall
portion 29 protect the hand of the user during the application of
fluid from brush 12 and interface with storage device 18.
[0028] In one alternative embodiment, flange 28 and tubular wall
portion 29 define an enclosure that is in fluid communication with
reservoir 23. In this alternative embodiment, brush 12 can
advantageously retain an additional volume of fluid that can be
dispensed from reservoir 23.
[0029] Handle 20 has an actuation mechanism 30 that includes a
switch 31 that is connected to a rod 40 for the selective opening
and closing of distal aperture 28. Switch 31 preferably slides
approximately parallel to the longitudinal axis along a first or
outer wall surface of a housing 32 and/or the outer surface of wall
22 on grip 24. Switch 31, as defined herein, can be any type of
knob, disk or button that produces movement that selectively seals
and unseals or opens aperture 28. Housing 32 is fixedly connected
to wall 22 on grip 24. The outer surface of the wall of housing 32
is approximately aligned with the surface of wall 22 of grip 24 and
is connected to one or more walls that extend into handle 20 and
define an operating space of predetermined dimensions. Housing 32
is isolated from reservoir 23 and vented to the external air. An
arm 33 is fixedly connected to switch 31 and extends into housing
32 approximately perpendicular to the longitudinal axis.
[0030] Continuing with the preferred embodiment, rod 40 has a
proximal end portion that is connected to arm 33 and a distal end
portion that includes a valve 41. Rod 40 extends from arm 33
through a sealed aperture 34 in housing 32 and through aperture 28
in the distal end portion of handle 20. Valve 41 moves in response
to the movement of switch 31 and selectively seals and opens
aperture 28. Housing 32 preferably includes a longitudinally
extending beam that assists in aligning the sliding movement of arm
33 and/or rod 40.
[0031] A first position of brush 12 is defined by valve 41 sealing
aperture 28 and switch 31 in a proximal position. A bias member 35
is positioned between arm 33 and housing 32 that urges arm 33 of
switch 31 and rod 40 proximally in housing 32 to seal aperture 28
closed. Bias member 35 is shown as a spring coiled around rod 40 in
this one embodiment, but bias member 35 could also be a leaf spring
or resilient polymer and use any alternative positioning between
housing 32 and arm 33. Bias member 35 has sufficient resilience to
retain a fluid tight seal of aperture 28 when brush 12 is
positioned at any angle and reservoir 23 is full of a fluid.
[0032] Referring now to FIGS. 2 and 3, rod 40 is preferably solid,
but has a cross-sectional shape perpendicular to the longitudinal
axis that varies to perform specific functions. For example, rod 40
in the vicinity of aperture 34 of housing 32 preferably has a
cylindrical outer shape and aperture 34 includes a seal that
interfaces with the cylindrical outer shape of rod 40 when static
and during any longitudinally directed movements to isolate housing
32 from any fluid in reservoir 23. Similarly, the portion of rod 40
that is in the vicinity of preferably circular aperture 28 changes
cross-sectional shape perpendicular to the longitudinal axis and/or
area from a solid cylinder that abuts valve 41 to a shape that
defines a cross-section with a reduced area. In one preferred
embodiment, the reduced cross-sectional area includes one or more
longitudinally aligned channels in rod 40. The portions of rod 40
in the vicinity of apertures 34 and 28, as defined herein, include
the length of rod 40 that interfaces with apertures 34 and 28
during the range of longitudinal movement of rod 40 between the
open and sealed positions of aperture 28.
[0033] Valve 41 includes a terminal end 42 that is connected to a
seal 43. The force of bias member 35 securely positions valve 41
directly against and precludes fluid flow from reservoir 23 through
aperture 28 in the first position of brush 12. In the preferred
embodiment, seal 43 has a cup shape that securely receives and is
attached to a disk shaped terminal end 42. A proximal side of seal
43 provides a fluid tight seal directly with a distal side of
aperture 28 in wall 22. The second position of brush 12 is defined
as switch 31 moved distally to position valve 41 in spaced relation
aperture 28 in wall 22 for fluid flow through aperture 28 from
reservoir 23.
[0034] As switch 31 is forwarded distally against the force of bias
member 35, rod 40 is also moved distally from the first position
sealing aperture 28 closed to the second position opening aperture
28. As rod 40 moves distally, the cross-sectional shape and/or area
of the portion of rod 40 directly in aperture 28 preferably changes
from a solid cylinder with a first cross-sectional area to a second
smaller cross-sectional area that increases fluid flow from
reservoir 23. In the preferred embodiment, the portion of rod 40
with the smaller cross-sectional area has a shape of a cross or an
"X" that defines one or more longitudinal channels. Thus, the
amount of distance switch 31 and rod 40 are forwarded distally
controls the size of the cross-sectional area directly in aperture
28. Aperture 28 in the open position is in fluid communication with
brush head 50 and reservoir 23.
[0035] In an alternative embodiment of brush 12, rod 40 includes
one or more disks 45 that distally advance the fluid in reservoir
23 when switch 31 is moved to the second position. This embodiment
can further include rod 40 having disk 45 that is a helical screw
and the movement of switch 31 initiating a rotational movement of
fluid along the longitudinal axis, for example, that forcefully
advances the fluid. This embodiment can advantageously provide
additional pressure on the fluid in reservoir 23 as it nears
emptying.
[0036] Brush head 50 has a wall 52 that defines a tubular shaped
conduit for the dispersing of fluid from brush 12. Brush head 50
has a distal end portion that includes a plurality of bristles 54
and a proximal end portion that connects to the distal end portion
of handle 20. Brush head 50 is preferably removably connected to
handle 20 by threads or a similar fluid sealing connector mechanism
as described previously between cap 26 and handle 20. The proximal
end portion of wall 52 of head 50 defines an aperture 57 and has a
first inside diameter that is greater than the inside diameter of
the distal end portion of head 50. The distal end portion of wall
52 defines an aperture 55. Apertures 55 and 57 are preferably
aligned with aperture 28 and the longitudinal axis. The inner
surface of wall 52 includes an approximately concave conical shape
that provides a distally directed tapered transition between the
larger first diameter of the proximal end portion and the smaller
second diameter of the distal end portion of brush head 50.
[0037] Referring now to FIGS. 1 and 4, storage device 18 provides a
storage receptacle for brush 12 and further includes a structure
for the positioning of a decorative insert 90. Storage device 16
includes a first or outer tube 60, a second inner tube 70 and a
base 80. Base 80 is constructed for positioning on a flat surface
such as a floor or shelf. First tube 60 and second tube 70 connect
with and extend upwardly from base 80.
[0038] In one preferred embodiment, first tube 60 has a tubular
wall 62 that defines an upper edge 63 and a lower edge 64. Upper
edge 63 includes a rim 65 that extends inwardly a predetermined
distance in a direction approximately perpendicular to longitudinal
axis-X'. A tubular wall 66 appends from rim 65 in the direction of
lower edge 64 a predetermined distance to a terminal free end. Wall
66 and rim 65 define an aperture 67 aligned with longitudinal
axis-X'. First tube 60 provides visibility to second tube 70 and is
preferably a tube with a solid wall that is made of a transparent
material such as glass or polymer. Alternatively, tube 60 can also
be made of non-transparent material that provides visibility
through a plurality of apertures defined in tube 60 such as those
that could be defined by a tubular wall 62 made of wires, bars or
plates, for example.
[0039] Wall 62 preferably has a tapered truncated conical shape
with a diameter that reduces from lower edge 64 to upper edge 63.
Tubular wall 66 is preferably tapered conversely with the terminal
free end having a smaller diameter than rim 65.
[0040] Second tube 70 has a tubular wall 72 that defines an upper
edge 73 that is a free end and a lower edge that is connected to a
bottom 74. Edge 73 defines an aperture that has a first diameter
that is preferably larger than the diameter of bottom 74. Edge 73
of wall 72 has a diameter that can be received in proximity to rim
65 between wall 62 and wall 66 of tube 60. Second tube 70 can have
a decorative design and/or color. Second tube 70 is preferably made
of polymer materials, but can also be constructed of glass, metal,
cellulose and composite materials. The outer surface of tubular
wall 72 can also be connected with a separate decorative layer 90
that can be temporary or permanently attached.
[0041] Continuing with this preferred embodiment, base 80 has a
first tubular wall 82 that defines an upper edge 83 that is a free
end and a lower edge that is connected to a bottom 84. Base 80 also
includes a second tubular wall 85 that is positioned in fixed
spaced relation to wall 82, has an upper edge 86 that is a free end
and a lower edge that is connected to bottom 84. Wall 85 defines a
recess with bottom 84 that receives bottom 74 of second tube 70 in
a close fitting relationship. An annular channel is defined between
wall 82, bottom 84 and wall 85. Base 80 is preferably made of a
resilient polymer or elastomer that has sufficient rigidity to
retain tube 70 and tube 80 in their respective positions.
[0042] In the preferred embodiment, storage device 18 is
advantageously constructed to display a decorative layer, wrapper
or sheath of material 90 such as a wall paper, ribbon, wrapping
paper or contact paper. The decorative layer of material 90 can be
a paper, polymer, natural fiber or any other substance that
provides the desired decorative effect.
[0043] As described previously, in operation the preferred
embodiment of storage device 18 first tube 60 provides visibility
to second tube 70. Storage device 18 can be readily disassembled
and decorative layer 90 attached to the outer surface of wall 72 of
second tube 70 to match, accent and/or coordinate with a desired
bathroom decor. Second tube 70 can include fasteners, such as one
or more recesses or projections that can assist in retaining
decorative layer 90 in position against wall 72. Decorative layer
90 is thus protected on the outside by second tube 70 and from the
inside by second tube 80 from any damage. Storage device 18 is then
reassembled.
[0044] As shown in FIGS. 1 and 4, in the operation of fluid
dispensing brush 10 the longitudinal axis-X of brush 12 is
approximately aligned with the longitudinal axis-X' for positioning
into and removal from container 18. The plurality of bristles 53
has a diameter that is approximately equal to or less than aperture
67. The positioning of the distal end 14 of brush 12 in container
18 is limited by flange 28. The rim of flange 28 has a diameter
that is greater than the diameter of aperture 67 of storage device
18. Tubular wall 29 and flange 28 interface with wall 66 and rim 65
aperture 67 to retain brush head 50 in a stable upright position in
storage device 18 with grip 24 extending approximately along the
longitudinal axis-X'. Second tube 70 retains any liquids that drip
from brush 12 while in the storage position and can be subsequently
removed from storage device 18. The drippings can be disposed of,
tube 70 cleaned, and storage device 18 reassembled. Brush 12 is
easily withdrawn from container 18 along longitudinal axis-X'.
[0045] Referring now to FIGS. 1-3, brush 12 in operation is
initially in the first position with actuation mechanism 30 biased
to make a fluid tight seal against aperture 28. Brush 12 is filled,
as required, with a fluid by opening cap 26 and filling reservoir
23 to a desired level. Cap 26 is replaced to seal reservoir 23
closed. Brush 12 can initially be used to scrub a surface without
the dispensing of fluid from reservoir 23 or the fluid can be
dispensed at the desired location prior to or during scrubbing.
[0046] To dispense the fluid, distal end portion 14 of brush 12 is
pointed downwards and aperture 55 is oriented in the direction of
the desired area for cleaning. Switch 31 on grip 24 is manually
actuated to forward arm 33 and rod 40 to open valve 41 for fluid
flow through second aperture 28. In the preferred embodiment, the
flow of fluid from brush 12 is due to gravity and/or the motion of
the grasping hand. If switch 31 is advanced a first predetermined
distance, the flow from reservoir 23 is limited to the gap defined
between the cylindrical portion of rod 50 and preferably circular
aperture 28. When switch 31 and rod 50 are fully advanced, the
fluid flow of reservoir 23 is increased due to the reduced
cross-sectional area of rod 50.
[0047] The flow from aperture 28 is interrupted by the proximal
side of valve 41 and is deflected towards the inner surface of wall
52 of head 50. The fluid advances distally approximately along the
inner surface of wall 52 along a converging approximately conical
path and then exits through aperture 55 as a stream of fluid.
Aperture 28, rod 40 and aperture 55 preferably have a directional
orientation along longitudinal axis-X.
[0048] The interruption of the flow from aperture 28 by valve 41
advantageously controls the rate and/or energy of the flow of the
fluid from reservoir 23. In particular, this interrupted flow
pattern limits the force of gravity on the rate of flow when
reservoir 23 is full and/or an excessively rapid movement of brush
12 is made in the first position. This combination of interrupted
and then collected flow pattern retains the control of the
direction and rate of the flow through aperture 55. The control of
the force of the fluid from brush 12 also advantageously limits the
undesired splash and/or spray that can result from fluid flows with
excessive energy.
[0049] In the preceding specification, the invention has been
described with reference to specific exemplary embodiments thereof.
It will however, be evident that various modifications,
combinations and changes may be made thereto without departing from
the broader spirit and scope of the invention as set forth in the
claims that follow. For example, the cross-sectional shapes and
areas perpendicular to the longitudinal axis of aperture 28 and rod
50 can each vary to provide a range of flow rates. Similarly, while
the present invention is described as a preferably gravity flow
device, it is understood that the present invention could be
readily modified to include a pressurized configuration. The
specification and drawings are accordingly to be regarded in an
illustrative manner rather than a restrictive sense.
