Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a compressed gas gun device
or a paint bullet gun, and more particularly to a compressed gas
gun device having an improved coupling device for attaching or
coupling different gas containers that have different
configurations thereto.
[0003] 2. Description of the Prior Art
[0004] Typical compressed gas guns comprise a gun body, a stock, a
trigger, a bullet loading guide, and a sight rack, in which the
bullet loading guide is secured onto the upper gun barrel, for
supplying projectiles or paint or lacquer bullets into the gun
barrel one at a time. Normally, a compressed air reservoir or gas
container or gas bottle is coupled to the stock or handle portion
of the gas gun, for supplying compressed air to force or to shoot
the projectiles or bullets out of the gun barrel.
[0005] For example, U.S. Patent Publication Ser. No. US
2002/0104523 A1 to Juan discloses one of the typical compressed gas
guns also comprising an upper gun barrel provided on top of a gun
body, a bullet loading guide attached onto the gun barrel, for
supplying projectiles or paint or lacquer bullets into the gun
barrel one at a time, and a compressed air reservoir or gas
container coupled to the handle portion of the gas gun, for
supplying compressed air to force or to shoot the projectiles or
paint or lacquer bullets out of the gun barrel.
[0006] However, various kinds of gas containers or gas bottles have
been developed and include different couplers or mouths that may
only be attached to the typical compressed gas guns having the
corresponding predetermined couplers or valves, but may not be
attached to the other compressed gas guns having different couplers
or valves, such that the users have to purchase the particular
compressed gas guns having the corresponding predetermined couplers
or valves.
[0007] U.S. Pat. No. 6,546,950 to Juan discloses another typical
compressed gas gun comprising an upper gun barrel provided on top
of a gun body, and a bullet feeding device attached onto the gun
barrel, for supplying projectiles or paint or lacquer bullets into
the gun barrel, and a compressed air reservoir or gas container
coupled to the handle portion of the gas gun, for supplying
compressed air to force or to shoot the projectiles or paint or
lacquer bullets out of the gun barrel.
[0008] In addition, a pressure-reducing valve is disposed or
coupled between the gun barrel and the compressed air reservoir or
gas container, for relieving the pressure built in the gun body,
and for allowing the compressed air reservoir or gas container to
be detached from the gun body when required.
[0009] However, similarly, only one kind of the typical gas
containers or gas bottles may be attached to the typical compressed
gas guns having the particular or predetermined couplers or valves,
and the other gas containers or gas bottles may not be attached to
the compressed gas guns having different couplers or valves.
[0010] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages of the conventional compressed
gas guns.
SUMMARY OF THE INVENTION

within the longitudinal bore of the casing, and includes a first
end for engaging with the valve stem, and a second end extended
toward the mouth of the first gas container, for selectively
engaging and depressing the valve rod into the first gas container
to selectively open the first gas container when the actuating
shank is moved along the longitudinal bore of the casing and moved
relative to the valve stem and the casing by the valve stem.
[0013] The casing includes a spring member disposed therein, and
engaged between the actuating shank and the casing, for biasing the
first end of the actuating shank to engage with the valve stem. The
casing includes an inner peripheral shoulder formed therein, and
communicating with the longitudinal bore thereof for engaging with
the spring member.
[0014] The actuating shank includes a pathway formed therein, to
allow the compressed gas to flow through the longitudinal bore of
the casing. The actuating shank includes an outer diameter smaller
than an inner diameter of the longitudinal bore of the casing, to
allow the compressed gas to flow through the longitudinal bore of
the casing.
[0015] The valve stem includes an inclined surface formed therein,
and located within the longitudinal bore of the casing, for
engaging with the second end of the actuating shank, and for
allowing the actuating shank to be moved along the longitudinal
bore of the casing and to be moved relative to the valve stem and
the casing by the inclined surface of the valve stem.
[0016] The valve stem includes a passage formed therein, for
selectively communicating with the orifice of the casing, when the
passage of the valve stem is offset from the valve seat of the
casing. The valve stem includes a sealing ring attached on valve
member thereof, for engaging or acting with the valve seat of the
casing, to selectively enclose and open the orifice of the
casing.
[0017] The valve stem includes an outer diameter smaller than an
inner diameter of the longitudinal bore of the casing, to allow the
compressed gas to flow through the longitudinal bore of the casing,
and to bypass the valve stem. A second gas container may further be
provided and may include a mouth for selectively coupling to the
coupling device, and the second gas container includes a control
device attached to the mouth thereof, to open and to enclose and to
control the second gas container.
[0018] Further objectives and advantages of the present invention
will become apparent from a careful reading of the detailed

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0026] Referring to the drawings, and initially to FIGS. 1-4, a
compressed gas gun device 1 in accordance with the present
invention comprises a gun body or housing 10, a gun barrel 11
formed or provided on top or in front of the housing 10, and a
stock or handle portion 12 provided or attached to bottom of the
housing 10, and having a trigger 13 for triggering or operating the
gas gun device 1.
[0027] A magazine or receptacle 14 is further provided and disposed
on top of the housing 10 with such as a detachable projectile
feeding tube 15, for receiving paint or lacquer bullets or
projectiles therein, and for supplying the projectiles or paint or
lacquer bullets into the housing 10 or the gun barrel 11. The
detachable projectile feeding tube 15 has been filed in the other
co-pending patent applications, but not related to the present
invention, and thus will not be described in further details.
[0028] The housing 10 includes a valve or coupling device 20
coupled to a hose 16 which is attached or coupled to the housing 10
or the gun barrel 11. The coupling device 20 in accordance with the
present invention is arranged and provided for coupling to various
kinds of compressed air reservoir or compressed air tank or gas
bottles or gas containers 50, 51 (FIGS. 4-7), and for supplying
compressed air or gas into the housing 10 or the gun barrel 11, in
order to force or to shoot the projectiles or bullets out of the
gun barrel 11.
[0029] The coupling device 20 includes a casing 21 having one end
22 directly attachable or coupled to the housing 10 or the gun
barrel 11, or indirectly coupled to the housing 10 or the gun
barrel 11 via the hose 16, and having an inner thread 23 formed in
the other end 24 thereof, for threading or attaching or securing
the mouths 52 of the gas containers 50, 51 thereto (FIGS. 4-7), and
thus for supplying the compressed air or gas into the housing 10 or
the gun barrel 11 via the coupling device 20. The casing 21 may be
secured to the handle portion 12 of the housing 10 with one or more
fasteners 18 (FIG. 3), for example.
[0030] As shown in FIGS. 4-7, the casing 21 includes a longitudinal
bore 25 formed therein, and communicating or coupling between the
housing 10 or the gun barrel 11 or the hose 16 and the gas
containers 50, 51 thereto, for allowing the compressed air or gas
to be supplied from the gas containers 50, 51 into the housing 10
or into the gun barrel 11 via the longitudinal bore 25 of the
coupling device 20. The casing 21 further includes an inner
peripheral shoulder 26 formed therein, and communicating with the
longitudinal bore 25 thereof.
[0031] The casing 21 further includes an orifice 27 laterally
formed therein, and intersecting or crossing or communicating with
the longitudinal bore 25 thereof, for rotatably and slidably
receiving a valve stem 30 of a valve device 3 therein, and further
includes an inner thread 28 formed or provided in one end of the
orifice 27 thereof and a valve seat 29 extended or provided in the
other end of the orifice 27 thereof.
[0032] For example, the valve stem 30 includes an outer thread 31
formed or provided in one end thereof for threading with the inner
thread 28 of the casing 21, for allowing the valve stem 30 to be
threaded and thus rotated and moved relative to the orifice 27 of
the casing 21, and includes a handgrip 32 formed or provided on the
one end thereof for operating or rotating the valve stem 30
relative to the casing 21.
[0033] The valve stem 30 is laterally extended through the
longitudinal bore 25 of the casing 21 and preferably includes an
outer diameter smaller than an inner diameter of the longitudinal
bore 25 of the casing 21, such that the valve stem 30 will not
block the longitudinal bore 25 of the casing 21, and such that the
compressed air or gas may flow through the longitudinal bore 25 of
the casing 21 and may bypass the valve stem 30.
[0034] However, it is preferable that the valve stem 30 includes a
cut off portion or a narrowed or reduced neck portion or inclined
surface 33 formed or provided therein, to form a valve member 34 in
the other end thereof, and the cut off portion or neck portion or
inclined surface 33 of the valve stem 30 is arranged to be located
within the longitudinal bore 25 of the casing 21, for allowing the
compressed air or gas to easily flow through the longitudinal bore
25 of the casing 21 and to bypass the valve stem 30, without being
blocked by the valve stem 30.
[0035] The valve member 34 of the valve stem 30 preferably includes
one or more sealing rings 35 attached thereon, for engaging or
acting with the valve seat 29 of the casing 21, and for either
enclosing or blocking the orifice 27 of the casing 21 (FIGS. 5, 7),
or opening the orifice 27 of the casing 21 (FIGS. 4, 6), for
allowing the compressed air or gas in the longitudinal bore 25 and
the orifice 27 of the casing 21 to flow out through or to be
released via the orifice 27 of the casing 21, at this moment.
[0036] For example, the valve stem 30 may include a passage 36
formed therein, for selectively communicating with the orifice 27
of the casing 21, when the passage 36 and/or the sealing rings 35
of the valve stem 30 are offset from the valve seat 29 of the
casing 21, for allowing the compressed air or gas to flow out of
the orifice 27 of the casing 21 via the passage 36 of the valve
stem 30. A retaining ring 37 may be attached to the valve stem 30,
and engageable with the valve seat 29 of the casing 21, for
limiting the valve stem 30 to slide or to move relative to the
casing 21, and for preventing the valve stem 30 from being
disengaged from the casing 21.
[0037] An actuating shank 40 may be optionally provided and
disposed within the longitudinal bore 25 of the casing 21, and
preferably includes an outer diameter smaller than an inner
diameter of the longitudinal bore 25 of the casing 21, for
preventing the actuating shank 40 from blocking the longitudinal
bore 25 of the casing 21, and for allowing the compressed air or
gas to flow through the longitudinal bore 25 of the casing 21 and
to bypass the actuating shank 40.
[0038] However, it is preferable that the actuating shank 40
includes one or more cut off portions or pathways 41 formed or
provided therein, and arranged to allow the compressed air or gas
to easily flow through the longitudinal bore 25 of the casing 21.
The actuating shank 40 includes one end or first end 42 for
engaging with the valve stem 30, such as for engaging with the cut
off portion or neck portion or inclined surface 33 of the valve
stem 30, for allowing the actuating shank 40 to be moved along the
longitudinal bore 25 of the casing 21 or to be moved relative to
the valve stem 30 and the casing 21 by the valve stem 30.
[0039] A spring member 43 may be engaged between the actuating
shank 40 and the inner peripheral shoulder 26 of the casing 21, for
biasing and forcing the first end 42 of the actuating shank 40 to
engage with the valve stem 30. The actuating shank 40 includes the
other end or second end 44 extended toward the other end 24 of the
casing 21 or toward the mouths 52 of the gas containers 50, 51, for
engaging or acting with the gas containers 50, 51, which will be
discussed hereinafter.
[0040] As shown in FIGS. 1 and 4-5, one type or one kind of the gas
containers 50 may include a conventional control ferrule or control
device 53 attached to the mouth 52 thereof, to open or to close or
to control the gas container 50. In operation, as shown in FIG. 5,
the valve member 34 of the valve stem 30 may be moved to engage or
act with the valve seat 29 of the casing 21, to enclose the orifice
27 of the casing 21, and to prevent the compressed air or gas from
flowing out through or released via the orifice 27 of the casing
21.
[0041] At this moment, the control device 53 may open the gas
container 50, to allow the compressed air or gas to flow from the
gas container 50, through the longitudinal bore 25 of the casing
21, and then into the housing 10 or the gun barrel 11. After use,
or when it is required to change the other gas container 50, the
gas container 50 may be closed or locked by the control device 53,
in order to prevent the compressed air or gas to further flow out
of the gas container 50.
[0042] However, when the gas container 50 is closed or locked, the
compressed air or gas filled or received within the longitudinal
bore 25 and the orifice 27 of the casing 21 may also include a
substantial pressure and is thus required to flow out through or to
be released via the orifice 27 of the casing 21, before the gas
container 50 may be disengaged and removed from the other end 24 of
the casing 21. Otherwise, the pressure of the compressed air or gas
may blow or blast the gas container 50 away from the casing 21 when
the gas container 50 is unthreaded relative to the casing 21.
[0043] As shown in FIG. 4, in this situation or condition, the
valve stem 30 may be threaded or rotated and moved relative to the
casing 21, to disengage the valve member 34 of the valve stem 30
from the valve seat 29 of the casing 21, and/or to open the orifice
27 of the casing 21, and thus to allow the compressed air or gas in
the longitudinal bore 25 and the orifice 27 of the casing 21 to
flow out through or to be released via the orifice 27 of the casing
21, and thus for allowing the gas container 50 to be removed and to
be changed to the other gas containers 50, 51.
[0044] As shown in FIGS. 6 and 7, illustrated is a different or
another type or kind of the gas container 51 also having the mouth
52 attached or threaded to the other end 24 of the casing 21, for
selectively supplying the compressed air or gas into the housing 10
or the gun barrel 11 via the coupling device 20. The type of the
conventional gas container 51 includes a probe or needle or valve
rod 54 provided and extended within the mouths 52 thereof, for
opening the gas container 51 in a conventional way when the valve
rod 54 is depressed into the gas container 51.
[0045] In operation, as shown in FIG. 7, the valve member 34 of the
valve stem 30 may also be moved or caused to engage or act with the
valve seat 29 of the casing 21, to enclose the orifice 27 of the
casing 21, and to prevent the compressed air or gas from flowing
out through or released via the orifice 27 of the casing 21. At
this moment, or when the valve member 34 is engage or act with the
valve seat 29 of the casing 21, the other end or second end 44 of
the actuating shank 40 may be actuated or forced by the valve stem
30 to depress and to force and to move the valve rod 54 into the
gas container 51, in order to open the gas container 51, and thus
to allow the compressed air or gas to be supplied from the gas
container 51 into the housing 10 or the gun barrel 11 via the
coupling device 20.
[0046] After use, or when it is required to change to the other gas
containers 50, 51, the actuating shank 40 may be caused to engage
with the inclined surface 33 of the valve stem 30 by threading or
rotating and moving the valve stem 30 relative to the casing 21,
and to disengage the other end or second end 44 of the actuating
shank 40 from the valve rod 54 of the gas container 51, in order to
close the gas container 51, and thus to prevent the compressed air
or gas to further flow out of the gas container 51.
[0047] As shown in FIG. 6, in this situation or condition, the
valve stem 30 may be threaded or rotated and moved relative to the
casing 21, to disengage the valve member 34 of the valve stem 30
from the valve seat 29 of the casing 21, and/or to open the orifice
27 of the casing 21, and thus to allow the compressed air or gas in
the longitudinal bore 25 and the orifice 27 of the casing 21 to
flow out through or to be released via the orifice 27 of the casing
21, and thus for allowing the gas container 51 to be removed and to
be changed to the other gas containers 50, 51.
[0048] It is to be noted that the valve device 3 may thus be formed
or acted as a relief valve device 3, for selectively releasing the
compressed air or gas received within the longitudinal bore 25 and
the orifice 27 of the casing 21, via the orifice 27 of the casing
21, when the gas containers 50, 51 have been enclosed, and thus for
preventing the gas containers 50, 51 from being blown or blasted
away from the casing 21 when the gas containers 50, 51 are
unthreaded relative to the casing 21.
[0049] Accordingly, the compressed gas gun device in accordance
with the present invention includes an improved coupling device for
attaching or coupling different gas containers that have different
configurations thereto.
[0050] Although this invention has been described with a certain
degree of particularity, it is to be understood that the present
disclosure has been made by way of example only and that numerous
changes in the detailed construction and the combination and
arrangement of parts may be resorted to without departing from the
spirit and scope of the invention as hereinafter claimed.
