DETAILED DESCRIPTION OF THE INVENTION
[0035] Referring to the drawings and initially to FIGS. 1-5, a BB
bullet feeding device of a toy gun in accordance with a first
embodiment of the present invention is horizontally mounted in a
barrel 101 of a gun body 10, and comprises a cylinder 1, a piston
cylinder 2, a front spring guide tube 3, a piston spring 4, a rear
spring guide tube 5, a nozzle 6, a sealing tube 7, a bullet feeding
spring 8, and a trigger operation set 9.
[0036] The gun body 10 is provided with a BB bullet supply portion
102 at a front end of the barrel 101, and a cocking handle 103 at
an upper portion of the BB bullet supply portion 102 to move
horizontally.
[0037] The cylinder 1 is secured on a rear portion of the BB bullet
supply portion 102, and has an inner portion divided by a front
section of the piston cylinder 2 into a left air chamber 11 and a
right air chamber 12.
[0038] The piston cylinder 2 is movable in the cylinder 1, and has
an inner portion formed with a U-shaped receiving chamber 21. The
piston cylinder 2 has a front end received in the cylinder 1, and a
rear end extended outward from a rear portion of the cylinder 1 and
formed with a piston push portion 22 rested on a distal end of the
cocking handle 103. The front end of the piston cylinder has an
outer wall formed with a locking recess 23.
[0039] The front spring guide tube 3 is secured in a front end of
the receiving chamber 21 of the piston cylinder 2, to horizontally
move with the piston cylinder 2 simultaneously.
[0040] The piston spring 4 may be compressed and extended, and has
a front end mounted on an outer wall of the front spring guide tube
3.
[0041] The rear spring guide tube 5 has a front end extended into a
rear end of the receiving chamber 21 of the piston cylinder 2, and
has a rear end secured to a distal end of the barrel 101. The
piston spring 4 has a rear end mounted on an outer wall of the rear
spring guide tube 5. The rear spring guide tube 5 has an inner
portion including a front section formed with a spring receiving
chamber 51 and a rear section formed with a guide rod through hole
52.
[0042] The nozzle 6 is a hollow cylinder, and has a front section
received in a rear section of a transverse hole 104 of the BB
bullet supply portion 102, a mediate section formed with multiple
air collection ports 61, and a rear section formed with an
insertion section 62. The transverse hole 104 of the BB bullet
supply portion 102 includes a mediate section provided with a
bullet feeding chamber 105 having a pressure applying portion 106,
and a front section provided with a bullet outlet tube 107.
[0043] The sealing tube 7 is formed with a U-shaped receiving space
71, and has a front section extended through a center of the front
spring guide tube 3 and secured on the insertion section 62 of the
nozzle 6 by multiple positioning bolts 72. The receiving space 71
of the sealing tube 7 has a mediate section formed with a through
hole 73. A locking hook 75 is pivoted in the receiving space 71 of
the sealing tube 7 by a hook bolt 74, and has an action portion 751
protruded outward from the through hole 73 and formed with a
locking opening 752. A T-shaped guide rod 76 is received in a rear
section of the receiving space 71 of the sealing tube 7, and has an
extension section 761 extended outward from a through hole 77
formed in a rear end of the sealing tube 7. The extension section
761 has a rear end received in the guide rod through hole 52 of the
rear spring guide tube 5. The guide rod 76 is secured with the
sealing tube 7 by a rod fixing bolt 78. The guide rod 76 has a
front section formed with a spring receiving chamber 762 for
receiving a hook push spring 763, and a hook push member 764 whose
front end face is rested on a rear end face of the locking hook
75.
[0044] The bullet feeding spring 8 is mounted on an outer wall of
the extension section 761 of the sealing tube 7, and received in
the spring receiving chamber 51 of the rear spring guide tube
5.
[0045] The trigger operation set 9 includes a trigger 91, a block
push member 92, and a locking block 93. The trigger 91 is pivoted
on a mediate section of the barrel 101 of the gun body 10 by a
trigger pivot axle 911. The block push member 92 has a lower end
pivoted on the trigger 91 by a pivot axle 921, and an upper end
provided with a push portion 922. The locking block 93 is pivoted
on the barrel 101 of the gun body 10 by a pivot axle 931, and
located above the block push member 92. The locking block 93 is
provided with a driven portion 932 that may mate with the push
portion 922 of the block push member 92.
[0046] In operation, referring to FIGS. 6-9 with reference to FIGS.
1-5, the cocking handle 103 may be pushed toward the rear portion
of the barrel 101. The piston push portion 22 of the piston
cylinder 2 is rested on the distal end of the cocking handle 103 so
that the piston cylinder 2 may be moved rearward with the cocking
handle 103 simultaneously, and the nozzle 6 and the sealing tube 7
may be moved rearward with the piston cylinder 2 simultaneously as
shown FIG. 6. Thus, the front end of the nozzle 6 is detached from
the top of the BB bullet supply portion 102, so that the BB bullet
108 may be pushed by an upward elastic force to enter the
transverse hole 104.
[0047] As shown in FIG. 6A, when the sealing tube 71 is moved
rearward, the locking hook 75 of the sealing tube 7 is lifted by an
inclined face "Z" of the rear spring guide tube 5, whereby the
locking opening 752 of the locking hook 75 may be detached from the
through hole 73 of the sealing tube 7, so that the sealing tube 7
and the nozzle 6 may be pushed forward by the restoring force of
the bullet feeding spring 8, to push the BB bullet 108 in the
transverse hole 104 to reach the position of the pressure applying
portion 106 of the bullet feeding chamber 105 as shown in FIG.
7.
[0048] During the stroke of the piston cylinder 2 pushed by the
cocking handle 103, when the locking block 93 rotated
counterclockwise enters the locking recess 23 of the piston
cylinder 2, movement of the piston cylinder 2 is stopped as shown
in FIG. 8, so that the driven portion 932 of the locking block 93
is engaged with the push portion 922 of the block push member
92.
[0049] Thus, when the trigger 91 is pressed as shown in FIG. 9, the
trigger 91 may be pivoted counterclockwise, to pivot and move the
block push member 92 upward, so that the push portion 922 of the
block push member 92 may push the driven portion 932 of the locking
block 93 upward, so as to pivot the locking block 93 clockwise,
thereby detaching the locking block 93 from the locking recess 23
of the piston cylinder 2, so that the piston cylinder 2 may be
pressed forward by the restoring force of the piston spring 4, to
compress the air contained in the left chamber 11 of the cylinder
1, so that the compressed air may be forced through the air
collection ports 61 of the nozzle 6 toward the bullet feeding
chamber 105, so that the BB bullet 108 located at the pressure
applying portion 106 may be ejected outward through the bullet
outlet tube 107 as shown in FIG. 9.
[0050] Referring to FIGS. 10 and 11, the BB bullet supply portion
102 of the BB bullet feeding device of a toy gun in accordance with
a second embodiment of the present invention is mounted on the top
of the barrel 101, and the cocking handle 103 is mounted on a side
of the BB bullet supply portion 102.
[0051] Accordingly, the BB bullet feeding device of a toy gun in
accordance with the present invention has the following
advantages.
[0052] 1. The piston cylinder 2 is moved in the cylinder 1
horizontally, and the BB bullet 108 may be rapidly and stably
pushed to the predetermined position by the restoring force of the
piston spring 4 and the bullet feeding spring 8 during the single
rearward stroke of the piston cylinder 2.
[0053] 2. The BB bullet 108 of the BB bullet feeding device may be
fed and triggered in a pneumatic manner easily and exactly, without
needing an electric power, thereby saving cost and natural
resource, and thereby increasing the lifetime of the BB bullet
feeding device.
[0054] 3. The BB bullet feeding device may be assembled and
dismantled easily and conveniently, thereby greatly facilitating
maintenance of the BB bullet feeding device.
[0055] 4. The piston cylinder 2 is received in the cylinder 1, and
horizontal movement of the piston 2 may feed the BB bullet 108
automatically, thereby facilitating the user employing the BB
bullet feeding device.
[0056] Although the invention has been explained in relation to its
preferred embodiment as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
