Description
BACKGROUND OF THE INVENTION
[0001] Keeping cool in any hot environment can be challenging.
Water has long been recognized as a preferred means for cooling,
but carrying and using water to cool a person is a challenge.
Misting water assists further in cooling and requires less water.
Portable personal misting devices, though, are a further challenge,
especially without using electrical powered delivery. Additionally,
a proper mist requires significant pressure, something few portable
powering devices can effectively supply. The current invention
solves these problems.
FIELD OF THE INVENTION
[0002] The current invention relates to water misting devices and
more specifically to a portable personal water misting apparatus
with counter pressure delivery.
SUMMARY OF THE INVENTION
[0003] The general purpose of the personal water misting device
with counter pressure delivery, described subsequently in greater
detail, is to provide a personal water misting device with counter
pressure delivery which has many novel features that result in an
improved personal water misting device with counter pressure
delivery which is not anticipated, rendered obvious, suggested, or
even implied by prior art, either alone or in combination
thereof.
[0004] The personal pressurized water misting apparatus with
counter pressure delivery is comprised of a rigid reservoir with a
flexible bladder within. The bladder is designed to hold water. The
bladder is acted upon by a movable pressure shelf. The pressure
shelf moves within the length of the reservoir. One example of the
invention offers a flexible, bendable bladder. This example allows
edges of the bladder to fold as needed in passing the edges of the
pressure platform. Other examples employ a flexible, expandable
bladder such that the bladder expands and contracts within the
reservoir and below the pressure shelf as needed with the influx
and outflow of water. One example of the invention is supplied as a
backpack. Yet another example is supplied as a belt with the
reservoir positioned as chosen. A filler with a check valve is
conveniently disposed on all examples of the invention. A filler
cap covers the filler. A one way check valve resides just within
the filler. The check valve is in sealed communication with the
bladder. The filler is a threaded female fitting. The fitting is a
typical water hose female fitting. The female hose fitting is
designed to accept a typical water hose threaded male fitting.
[0005] A water hose is used to fill the bladder of the invention.
Water hoses typically supply water pressure from 35-100 pounds per
square inch (psi).
[0006] A pressure shelf is disposed within the reservoir. A
compression spring is anchored within the reservoir. Still other
examples of the invention utilize more than one spring. In the
backpack example of the invention, each spring is anchored against
the inside of the top of the reservoir in a spring rest. The
opposite end of each spring is anchored in a spring rest against
the pressure shelf. In the waist belt example of the invention, the
spring is anchored against in inner end of the reservoir opposite
the filler end. The spring is between the end of the reservoir and
the pressure shelf. The pressure shelf acts against the bladder to
pressure the water contained within the bladder. As water hose is
used to fill the bladder. Water pressure presses against the
pressure shelf. The spring is thereby compressed. Spring
compression ceases when pressure within the bladder equals water
pressure from the hose supplied to the invention. The air within
the reservoir but not within the bladder is compressed. Therefore
the springs and the air pressure are imposing an expansion force
against the pressure shelf. When internal pressure equals that of
the water pressure applied, the check valve sees equilibrium and
closes. Withdrawing the water hose from the invention therefore
does not allow water flow out of the invention.
[0007] In an additional example of the invention, the pressure
within the bladder is further enhanced by a handle operated
mechanism. The mechanism is used after the bladder is filled with
water.
[0008] The handle operated mechanism comprises a handle external to
the reservoir. The handle is generally T-shaped. The handle extends
into a sleeve. The sleeve passes through the reservoir top. The
passage of the sleeve through the reservoir is fitted with a seal.
Air pressure is prevented from escaping from the reservoir by the
seal. A plunger is fitted to the sleeve, within the reservoir. As
the handle is pushed inward toward the reservoir, the plunger
compresses the spring circling about the handle sleeve. The sleeve
is guided by a rod that slideably fits within the sleeve. The rod
is anchored to the pressure shelf. The sleeve exterior to the
reservoir is fitted with a perpendicularly affixed t-lock. The top
of the reservoir exterior is fitted with a lock tab. The lock tab
accepts the t-lock of the sleeve. The T-handle is pushed into the
reservoir until the t-lock is aligned with the abbreviated lock
tab. The t-lock is then twisted. The sleeve and handle are thereby
held in a position which compresses the spring within the
reservoir, thereby retaining the spring pressure resulting from
compressing the plunger against the spring force. This additional
spring pressure provides for the plunger to exert more pressure
against the pressure shelf, thereby further pressuring the water
held within the reservoir bladder to a psi greater than what only
the water pressure filling can provide.
[0009] The filling water pressure exerts pressure against the
pressure shelf, such that pressurized filling of the bladder moves
the pressure shelf, thereby compressing springs within the bladder,
whereby counter pressure delivery is actuated with the on/off
control. The on/off control is fitted within the flex tube. The
flex tube exits the bladder and passes outside of the
reservoir.
[0010] The flex tube provides for positioning the delivery of water
from the bladder as desired. One example of the invention provides
a misting nozzle at the end of the flex tube. The misting nozzle
is, in one example, fitted to the top of a hat. Turning on the
on/off control allows for water pressure to force water into the
misting nozzle, thereby spraying water mist above and outward from
the top of the hat. The on/off control offers graduated opening
such that mist volume is controlled. Still another example of the
invention offer a stream nozzle with a trigger. The water stream
provided is controlled by the trigger, much as a typical water gun.
Various other nozzles and water deliveries are provided.
[0011] The invention therefore offers counter pressure delivery of
water in mist or stream form. The reservoir's internal compression
of air and springs by the pressurized introduction of water stores
the potential energy. The examples of the invention featuring added
spring pressure via the plunger and handle further store additional
energy. The on/off control provides for releasing that stored
energy by forcing water out through the delivery system. No pumping
or electric pumps are required.
[0012] Thus has been broadly outlined the more important features
of the personal water misting device with counter pressure delivery
so that the detailed description thereof that follows may be better
understood and in order that the present contribution to the art
may be better appreciated.
[0013] Numerous objects, features and advantages of the personal
water misting device with counter pressure delivery will be readily
apparent to those of ordinary skill in the art upon reading the
following detailed description of presently preferred, but
nonetheless illustrative, examples of the personal water misting
device with counter pressure delivery when taken in conjunction

DETAILED DESCRIPTION OF THE DRAWINGS
[0023] With reference now to the drawings, and in particular FIGS.
1 through 6 thereof, example of the personal water misting device
with counter pressure delivery employing the principles and
concepts of the present invention and generally designated by the
reference number 10 will be described.
[0024] Referring to FIG. 1, the invention 10 is comprised of a
reservoir 12. The reservoir 12 is further comprised of vertical
panels: front (not shown), an opposite spaced apart back 47, and
two opposing spaced apart sides 46. The back 47 and the sides 46
are connected by vertical rounded corners 45. The front is meant to
be worn against a user (not shown) in a backpack (not shown). The
threadably removable filler cap 24 is disposed on the lower portion
of one side 46. The horizontal top 48 and bottom 43 affix to the
outer edges of the front, back 47, sides 46 and rounded corners 45
to seal the reservoir. A flex tube 14 transfers water from the
reservoir 12 to the nozzle 16. The nozzle 16 is fitted atop the hat
18. Water mist 50 emanates from the nozzle 16 to surround the hat
18 and fall beyond the hat 18.
[0025] Referring to FIG. 2, the reservoir is internally comprised
of a flexible bladder 20. The bladder 20 fits internally against
sides 46, bottom 43 and back 47 (FIG. 1), and front (not shown).
The bladder 20 also substantially fits against the pressure shelf
34.
[0026] Edges of the bladder 20 are provided for passing relief
beyond the edges of pressure shelf 34 as the pressure shelf 34
moves downward against the water 52. The springs 30 are therefore
in a partially compressed state. The springs 30 reside vertically
and are captured at both top and bottom by springs rests 31. The
upper spring rests 31 are supportedly fixed against the top inside
49 of the reservoir 12. The lower spring rests 31 are supportedly
affixed to the top of the pressure shelf 34. The compression
springs 30 are thereby captured and forced to work in the vertical
plane in compression. The flex tube 14 is fitted with on/off
control 32. On/off control 32 provides for metered release of water
52 from bladder 20.
[0027] Referring to FIG. 3, the belt 38 example of the invention 10
is clasped about a user by the typical buckle 40. The reservoir 12
is disposed horizontally along a portion of the belt 38. The
reservoir 12 is fitted with easily accessed threaded filler cap 24.
Filler cap 24 covers filler 21. the flex tube 14 extends to meet
the hat 18. The mist nozzle 16 is fitted atop hat 18. Mist nozzle
16 disperses water mist 50 about and beyond hat 18.
[0028] Referring to FIG. 4, the reservoir 12 of FIG. 3 is partially
filled with water 52. The spring 30 is half compressed. Water hose
56 is connected to the female connection (not shown) of the filler
21. Water flow 58 is flowing toward and within the bladder 20 of
the reservoir 12. Water 52 pressure is acting against the spring
pressure of spring 30. Spring 30 is pushing against the plunger 26.
Water 52 pressure is pushing against the bladder 20. Bladder 20
thereby pushes against the plunger 26. Water 52 pressure causes the
spring 30 to compress until pressure is equalized between incoming
water flow 58 and spring 30 pressure.
[0029] The plunger 26 is affixed to linear sleeve 25. The sleeve 25
slideably surrounds the rod 28. The rod 28 is firmly affixed to the
rod stop 29 within the end of the reservoir 12 opposite the filler
21. The spring 30 is fully compressed when the sleeve 25 reaches
the rod stop 29.
[0030] Referring to FIG. 5, the T-handle of the backpack example of
the invention 10 is in the fully compressed locked position. The
sleeve 25 is fitted with perpendicular t-lock 33. The T-handle 23
has been twisted such that the t-lock 33 is caught under the lock
tabs 35. The lock tabs 35 are affixed to the top 48 of the
reservoir 12. The flex tube 14 emanates from the side 46 of the
reservoir 12 opposite the filler 21 and filler cap 24. The flex
tube 14 is fitted with a tube clip 54 for conveniently clipping to
a user.
[0031] Referring to FIG. 6, the sleeve 25 of the T-handle 23
partially surrounds rod 28, within the reservoir. The t-lock 33 is
above and disengaged from the lock tabs 35. Lock tabs 35 are
affixed to the top 48 of the reservoir 12. the sleeve 25 passes
into the reservoir 12 via sleeve seal 27. Sleeve seal 27 prevents
air pressure leak from the inside of reservoir 12. Plunger 27 is
affixed to the bottom of the sleeve 25. Plunger 27 is forced
against the top inside 49 of the reservoir 12. The springs 30 are
extended. The on/off control 32 of flex tube 14 is off.
[0032] In use, the filler cap 24 is removed from the filler 21. A
male fitting of a water hose 56 is hooked to the female fitting
(not shown) of the filler 21. The on/off control 32 is turned off.
The hose 56 is turned on. Water flow 58 flows into the bladder 20
of the invention 10.
[0033] The pressure shelf 34 pushes against springs 30, thereby
compressing the springs 30 until the water 52 pressure equals the
air pressure and the spring 30 pressure within the reservoir. Water
52 ceases to flow into the bladder 20. The hose 56 is removed. The
check valve (not shown) within the filler 21 prevents backflow of
the water 52 from within the bladder 20. The water 52 within the
reservoir 12 is pressurized equivalent to the water 52 that was
dispensed to the reservoir from a water 52 faucet. With the more
complete example of the invention 10, the T-handle 23 with sleeve
25 and plunger 26 is employed to further increase internal water 52
pressure within the bladder 20. The T-handle 23 is used after the
bladder 20 is filled with water 52. The T-handle 23 is then twisted
a partial turn and pushed within the reservoir 12 until the t-lock
33 stops against the top 48 of the reservoir 12. The plunger 26 is
thereby pushed against the spring 30. The spring 30 is compressed.
The T-handle 23 is twisted back such that the t-lock engages the
lock tabs 35. The T-handle 23 thereby locks into position and holds
the tension against the spring 30. This tension increases the
pressure applied to the pressure shelf 24, thereby increasing
outflow pressure of water 52 through the flex tube 14.
[0034] In one example of use, the hat 18 is placed atop a user's
head. The on/off control 32 is turned on. The flow of the water 52
through the control 32 is adjustably metered by the control 32
position. The water 52 flows to and through the misting nozzle 16.
Water mist 50 is thereby dispersed above a user's head.
[0035] In an additional example of the invention 10, the stream
nozzle (not shown) is used. The stream nozzle is fitted with a
trigger switch (not shown) for triggering the stream spray of water
52 from the nozzle. In either example of the invention 10, the tube
clip 54 is clipped to a user to more conveniently position and hold
the flex tube 54.
[0036] With respect to the above description then, it is to be
realized that the optimum dimensional relationships for the parts
of the personal water misting device with counter pressure
delivery, to include variations in size, materials, shape, form,
function and the manner of operation, assembly and use, are deemed
readily apparent and obvious to one skilled in the art, and all
equivalent relationships to those illustrated in the drawings and
described in the specification are intended to be encompassed by
the present invention.
[0037] Directional terms such as "front", "back", "in", "out",
"downward", "upper", "lower", and the like may have been used in
the description. These terms are applicable to the examples shown
and described in conjunction with the drawings. These terms are
merely used for the purpose of description in connection with the
drawings and do not necessarily apply to the position in which the
present invention may be used.
[0038] Therefore, the foregoing is considered as illustrative only
of the principles of the invention. Further, since numerous
modifications and changes will readily occur to those skilled in
the art, it is not desired to limit the invention to the exact
construction and operation shown and described, and accordingly,
all suitable modifications and equivalents may be resorted to,
falling within the scope of the invention.
