Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The present invention is a Continuation-In-Part of U.S.
patent application Ser. No. 11/807,102, filed May 25, 2007, the
contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The invention relates generally to a device for discharging
a stream of fluid, and more particularly to a device that includes
a water pump, a trigger mechanism, and a secondary fluid
chamber.
[0004] 2. Description of the Related Art
[0005] Various devices for discharging a stream of fluid, such as a
pneumatic water gun, for example, are known. Most pneumatic water
guns use air pressure to force water out of a nozzle and into the
air. These types of water guns utilize one of two types of
propulsion systems: a pressurized reservoir system, or a separate
firing chamber system.
[0006] Water guns that use the pressurized reservoir system have a
single reservoir for air and water. The reservoir is first
partially filled with water, then air is forced in under pressure.
When a trigger is pulled, the pressurized air forces water out of
the reservoir
[0007] Water guns that use the separate firing chamber system have
a large reservoir for water only, and one or more smaller firing
chambers. In this system, water is pumped from the reservoir into
the firing chamber(s), compressing the air in the chamber(s). This
exerts a force on the water, thus providing the power to push the
water through the nozzle when the trigger is pulled.
SUMMARY OF THE INVENTION
[0008] In one aspect, the invention involves an apparatus for
discharging a stream of fluid. The apparatus includes a fluid
reservoir, a secondary fluid chamber in fluid communication with
the fluid reservoir, a ratchet mechanism that includes a plurality
of teeth, a piston slidably disposed in the secondary fluid
chamber, and a spring. The ratchet mechanism is movable between a
first position and a second position. The spring urges the ratchet
mechanism toward the second position. The piston is configured to
draw fluid from the fluid reservoir into the secondary fluid
chamber when the ratchet mechanism is moved toward the first
position and to discharge the fluid from the secondary fluid
chamber during spring induced movement of the ratchet mechanism to
the second position. The apparatus further includes a manually
actuatable trigger mechanism that includes a pawl that interacts
with the teeth and is movable from a rest position to a pulled
position. The trigger mechanism is configured to arrest the spring
induced movement of the ratchet mechanism in the rest position and
allow the spring induced movement of the ratchet mechanism in the
pulled position.
[0009] In one embodiment, the apparatus further includes a handle
selectively connectable to the ratchet mechanism and configured to
manually move the ratchet mechanism to the first position against
the urgency of the spring.
[0010] In another embodiment, the apparatus further includes a pump
mechanism in fluid communication with the fluid reservoir through a
conduit.
[0011] In still another embodiment, the handle is selectably
connectable to the pump mechanism. The handle is movable from a
first position to a second position, and the handle is connected to
the ratchet mechanism in the first position and connected to the
pump mechanism in the second position to pump air into the fluid
reservoir to increase pressure in the fluid reservoir.
[0012] In yet another embodiment, the apparatus further includes a
one-way valve arranged between the pump mechanism and the fluid
reservoir allowing a flow only from the pump mechanism toward to
the fluid reservoir.
[0013] In still another embodiment, the apparatus further includes
a fluid output port through which the fluid is discharged.
[0014] In another embodiment, the secondary fluid chamber comprises
a one-way valve.
[0015] In yet another embodiment, a secondary fluid chamber is in
fluid communication with the fluid reservoir via a hose in fluid
communication with the fluid reservoir and the one-way valve.
[0016] In still another embodiment, the secondary fluid chamber is
in fluid communication with the fluid output port via a hose.
[0017] Other objects and features of the present invention will

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS
[0023] The invention relates to a device for discharging a stream
of fluid, that includes a water pump, a trigger mechanism, a
ratchet mechanism, a fluid reservoir, and a secondary fluid
chamber. A pump handle is used to move a piston that draws the
fluid from the fluid reservoir into the secondary fluid chamber
before discharge. The pump handle is also used to selectively
connect the trigger mechanism to the ratchet mechanism to allow
incremental discharge of the fluid.
[0024] Referring to FIG. 1, in one embodiment, an illustrative
schematic diagram of a water gun 100 employing a ratcheted pump
handle 118 and trigger mechanism 120 is shown. The water gun 100
includes a body portion 106, a handle portion 102, a barrel portion
104, and a fluid reservoir 112 for storing a fluid, such as water,
for example. The fluid reservoir 112 includes a fluid input port
114, and the barrel portion 104 includes a fluid output port 110. A
"C" shaped slot 119 extends longitudinally along one side of the
barrel portion 104, through which the pump handle 118 extends and
couples to a pump mechanism 224 or ratchet mechanism 206 (see FIG.
2) disposed inside the body portion 106. The "C" shaped slot 119
includes an upper horizontal slot 116, a lower horizontal slot 115,
and a vertical slot 117.
[0025] Referring to FIGS. 2A and 2B, in one embodiment,
illustrative schematic diagrams of the a pump mechanism 224, a
ratchet mechanism 206, and a trigger mechanism 120 disposed inside
the body portion 106 of the water gun 100 in pump mode (FIG. 2A)
and shoot mode (FIG. 2B) are shown.
[0026] The pump mechanism 224 includes a piston 240 that includes
pins 226a and 226b that contact the handle 118 during pumping mode.
The pump mechanism further includes a one-way valve 228. The pump
mechanism 224 is in fluid communication with the reservoir 112 via
a tube 230.
[0027] The ratchet mechanism 206 includes a contact portion 222
that contacts handle 118 during firing mode. The ratchet mechanism
206 further includes teeth 208, piston (or plunger) 232, piston rod
236, and spring 212. The piston 232 and piston bar 236 are slidably
disposed inside a secondary fluid chamber 204, which includes a
one-way valve 216 and is in fluid communication with the reservoir
112 via a hose 214. The secondary fluid chamber 204 is also in
fluid communication with the fluid output port 110 via a hose 202.
In another embodiment, a pressure valve is disposed between the
hose 202 and the secondary fluid chamber 204 which only allows
fluid to pass from the secondary fluid chamber 204 to the hose 202
if a minimum pressure is exceeded.
[0028] The handle 118 rotates on, and slides along a guide bar 218.
The trigger mechanism 120 includes a pawl 210. The trigger
mechanism 120 rotates on a pivot pin 234. The pawl is held to
engage the teeth 208 by a spring (not shown). When the trigger 120
is pulled against the force of the spring, the pawl 210 disengages
from the teeth 208.
[0029] Although the present embodiment discloses hoses or tubes for
conducting fluid between the various parts of the water gun, any
conduits which conduct the fluid may be used, such as channels
formed in the body portion 106, the barrel portion 104, or the
handle portion 102.
[0030] In one embodiment, in pump mode, the handle 118 is rotated
about the guide bar 218 in an upward direction in slot 117 (in the
direction shown by arrow 122 of FIG. 1) to engage the pins 226a and
226b. Instead of pins 226a and 226b, any known or hereafter
developed structure which creates an engagement between the handle
118 and the piston 240 may be used. To ensure that the pins 226a
and 226b or other structure remains aligned with the handle 118, a
spring 241 may be arranged in the pump mechanism to urge the piston
240 in the forward position shown in FIG. 2A while the handle 118
is disengaged from the piston 240. Alternatively, another
releasable mechanism may be used to hold the piston 240 in the
forward position, the mechanism being released to allow pumping
movement when the handle is engaged with the piston. The engagement
of the handle 118 with the piston 240 causes the piston to move
with the handle 118 when the handle is pulled back along slot 116.
The piston 240 pumps air through the one-way valve 228 and the hose
230 into the reservoir 112. This pumping action increases the
pressure in the reservoir 112. The pumping action can be executed
one or more times.
[0031] After pumping has been completed, the handle 118 is moved
forward to slot 117 and rotated about the guide bar 218 in a
downward direction (in the direction shown by arrow 124 of FIG. 1)
to contact the contact portion 222. The engagement of the handle
118 with the contact portion causes the piston 232 to move with the
handle 118 when the handle 118 is pulled back along slot 115. The
movement of the piston 232 draws fluid from the reservoir 112
through the hose 214 and through the one-way valve 216 and into the
secondary fluid chamber 204. The piston 232 moves against the
urgency of spring 212 as the piston 232 is moved out of the
secondary fluid chamber 204 by the handle.
[0032] After the handle 118 has been pulled to the end of slot 115,
the water gun 100 can be fired. To fire the water gun 100, a user
pulls the trigger 120, which rotates on pin 234, to disengage the
pawl 210 from the teeth 208 on the ratchet mechanism 206. The
spring 212 urges the piston 232 into the secondary fluid chamber
204 to force the fluid through the hose 202 and through the fluid
output port 110. The ratchet mechanism 206 will continue to move in
response to the spring force as long as the trigger 120 is pressed
and until the handle 118 moves to the end of the slot 115. Once a
user stops pressing the trigger 120, the pawl 210 engages the teeth
208 and stops the ratchet mechanism 206 from moving. The user can
stop and resume firing until the piston 232 is fully inserted into
the secondary fluid chamber 204. Accordingly, the handle 118 does
not have to be pulled all the way out to the back of the slot 115
to enable firing of the water gun.
[0033] Referring to FIG. 3, in another embodiment, an illustrative
schematic diagram of a ratchet mechanism 302 and a trigger
mechanism 120 disposed inside a body of a water gun is shown.
[0034] The ratchet mechanism 302 includes handle 304, teeth 310,
piston (or plunger) 308, piston rod 306, and spring 312. The piston
308 and piston rod 306 are slidably disposed inside a secondary
fluid chamber 316, which includes a one-way valve 216 and is in
fluid communication with the reservoir 112 via a hose 314. The
secondary fluid chamber 316 is also in fluid communication with
fluid the output port 110 via a hose 202. As disclosed above, a
pressure valve may be disposed between the hose 202 and the
secondary fluid chamber 316.
[0035] The handle 304 rotates on, and slides along a guide bar 218.
The trigger mechanism 120 includes the pawl 210. The trigger
mechanism 120 rotates on a pivot pin 234. The pawl is held to
engage the teeth 310 by a spring (not shown). When the trigger 120
is pulled against the force of the spring, the pawl 210 disengages
from the teeth 310.
[0036] In this embodiment, in operation, the handle 304 is pulled
back along a single slot (not shown) in the body of the water gun
to move the piston 308 to draw fluid from the reservoir 112 through
the hose 214 and through the one-way valve 216 and into the
secondary fluid chamber 316.
[0037] After the handle 304 has been pulled to the end of the
single slot, the water gun can be fired. To fire the water gun, a
user pulls the trigger 120, which rotates on pin 234, to disengage
the pawl 210 from the teeth 310 on the ratchet mechanism 302. The
spring 312 urges the piston 308 into the secondary fluid chamber
316 to force the fluid through the hose 202 and through the fluid
output port 110. The ratchet mechanism 302 will continue to move as
long as the trigger 120 is pressed and until the handle 304 moves
to the end of the slot. Once a user stops pressing the trigger 120,
the pawl 210 engages the teeth 310 and stops the ratchet mechanism
302 from moving. The user can stop and resume firing until the
piston 308 is fully inserted into the secondary fluid chamber 316.
Accordingly, the handle 304 does not have to be pulled all the way
out to the back of the slot 115 to enable firing of the water
gun.
[0038] Variations, modifications, and other implementations of what
is described herein may occur to those of ordinary skill in the art
without departing from the spirit and scope of the invention.
Accordingly, the invention is not to be defined only by the
preceding illustrative description.
[0039] Thus, while there have shown and described and pointed out
fundamental novel features of the invention as applied to a
preferred embodiment thereof, it will be understood that various
omissions and substitutions and changes in the form and details of
the devices illustrated, and in their operation, may be made by
those skilled in the art without departing from the spirit of the
invention. For example, it is expressly intended that all
combinations of those elements and/or method steps which perform
substantially the same function in substantially the same way to
achieve the same results are within the scope of the invention.
Moreover, it should be recognized that structures and/or elements
and/or method steps shown and/or described in connection with any
disclosed form or embodiment of the invention may be incorporated
in any other disclosed or described or suggested form or embodiment
as a general matter of design choice. It is the intention,
therefore, to be limited only as indicated by the scope of the
claims appended hereto.
