15.
[0040] The power set 2 includes a motor 21, a first drive gear 22,
a second drive gear 23, and a force output gear 24. The force
output gear 24 has multiple teeth arranged in a sector shape, and
has a center provided with an idler 242 which has an insertion
recess 241.
[0041] Referring to FIGS. 1 and 1-1, the trigger operation set 3
includes a trigger 31, a connecting arm push plate 32, a trigger
arm 33, a lift member 34, a connecting arm 35, a switch arm 36, a
locking member 37, and a microswitch 38.
[0042] The trigger 31 has a top end having a first side pivoted
with a front end of the trigger arm 33 by a pivot axle 311, and a
second side formed with an arcuate recess 310. The trigger 31 has a
mediate section pivoted with a front end of the connecting arm push
plate 32 by a pivot axle 312. The connecting arm push plate 32 has
a mediate section formed with a lug insertion hole 321. The trigger
arm 33 has a rear end pivoted with a lower end of the lift member
34 by a pivot axle 331. The lower end of the lift member 34 has an
arcuate portion received in the arcuate recess 310 of the trigger
31. The lower end of the lift member 34 has a wall protruded with a
connecting arm resting block 341. The lift member 34 has an upper
end provided with an upper resting block 342 and a side resting
block 343. The connecting arm 35 has a lower end pivoted above the
connecting arm push plate 32 by a pivot axle 351, and provided with
a lug 352 that may be inserted into the lug insertion hole 321 of
the connecting arm push plate 32. The connecting arm 35 has an
upper end formed with a resting block insertion recess 353 for
receiving the connecting arm resting block 341 of the lift member
34.
[0043] The switch arm 36 may be moved horizontally, and has a rear
end provided with an idler push portion 361, a mediate section
provided with a push action block 362, and a front end provided
with an inclined press face 363. The microswitch 38 is mounted
under the front end of the switch arm 36, and includes a press
button 381 that may be pressed by the inclined press face 363 of
the switch arm 36. The front end of the switch arm 36 is formed
with a receiving recess 364 for receiving a push arm spring 365 and
a mounting rod 366.
[0044] The locking member 37 is pivoted above the push action block
362 of the switch arm 36 by a pivot axle 371, and has an upper end
provided with a locking lug 372, a side portion provided with a
first driven portion 373 and a second driven portion 374, and a
lower end provided with a drive block 375.
[0045] In operation, the cocking handle 103 may be pushed toward
the rear portion of the barrel 101. The piston push portion 122 of
the piston cylinder 12 of the bullet feeding device 1 is rested on
the distal end of the cocking handle 103 so that the piston
cylinder 12 may be moved rearward with the cocking handle 103
simultaneously, and the nozzle 16 and the sealing tube 17 may be
moved rearward with the piston cylinder 12 simultaneously. Thus,
the front end of the nozzle 16 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.
[0046] When the sealing tube 17 is moved rearward, the locking hook
175 of the sealing tube 17 is lifted by an inclined face of the
rear spring guide tube 15, to detach from the through hole 173 of
the sealing tube 17, so that the sealing tube 17 and the nozzle 16
may be pushed forward by the restoring force of the bullet feeding
spring 18, 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. 2.
[0047] Thus, the single-stroke horizontal movement of the piston
cylinder 12 may force the BB bullet 108 to reach the position of
the pressure applying portion 106 of the bullet feeding chamber 105
as shown in FIG. 2, to be ready for shooting. At this time, the
locking lug 372 of the locking member 37 may enter the locking
recess 123 of the piston cylinder 12, and the drive block 375 is
moved with the counterclockwise rotated locking member 37 to detach
from the push action block 362 of the switch arm 36 as shown in
FIG. 2-1, so that the switch arm 36 may be pushed rearward by the
restoring force of the push arm spring 365, and the idler push
portion 361 of the switch arm 36 may be inserted into the insertion
recess 241 of the idler 242 of the force output gear 24. At this
time, the press button 381 of the microswitch 38 is disposed at a
closed state.
[0048] As shown in FIGS. 3 and 3-1, when the trigger 31 is pressed,
the upper resting block 342 and side resting block 343 of the lift
member 34 may push the first driven portion 373 and second driven
portion 374 of the locking member 37 upward, so that the locking
member 37 may be rotated clockwise, thereby detaching the locking
lug 372 of the locking member 37 from the locking recess 123 of the
piston cylinder 12.
[0049] At this time, the drive block 375 is moved with the
clockwise rotated locking member 37 to push and move the push
action block 362 of the switch arm 36 toward the front portion of
the gun body 10 as shown in FIGS. 4 and 4-1, so that the press
button 381 of the microswitch 38 may be pressed by the inclined
press face 363 of the switch arm 36, thereby opening the
microswitch 38 which may start and operate the motor 21 which may
counterclockwise rotate the force output gear 24 which meshes with
and moves the rack 125 of the piston cylinder 12, so as to move the
piston cylinder 12 forward, thereby increasing the pressure in the
cylinder 12. Thus, the forward movement of the piston cylinder 12
may be accelerated by the restoring force of the piston spring 14
and by the power provided by the force output gear 24 co-operating
with the rack 125, whereby the BB bullet 108 located in the bullet
feeding chamber 105 may be pushed forward by the pressure caused by
the forward movement of the piston cylinder 12, so that the BB
bullet 108 may be ejected outward.
[0050] Referring to FIGS. 5 and 6, the BB bullet supply portion 102
of the BB bullet feeding device 1 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 horizontal forward movement of the piston cylinder 12
may be accelerated by the restoring force of the piston spring 14
and by the power provided by the force output gear 24 co-operating
with the rack 125, thereby greatly increasing the pressure in the
cylinder 11, so that the BB bullet 108 may be ejected outward
quickly and conveniently.
[0053] 2. The locking lug 372 of the locking member 37 may be
locked with the locking recess 123 of the piston cylinder 12, so
that the force output gear 24 and the rack 125 will not bear any
load at a normal state, thereby saving the power source.
[0054] 3. The piston cylinder 12 may be moved in the cylinder 11
freely, the force output gear 24 may mesh with and detach from the
rack 125 easily, and the microswitch 38 may be opened by the switch
arm 36.
[0055] 4. The force output gear 24 will not mesh with the rack 125
in a normal state, thereby decreasing the load of the motor 21, and
thereby increasing the lifetime of the toy gun.
[0056] 5. As shown in FIG. 4-1, the trigger 31 may be pressed
continuously, whereby the resting block insertion recess 353 of the
connecting arm 35 is rested on the connecting arm resting block 341
of the lift member 34, so that the switch arm 36 may connect the
electric power successively, so that the BB bullet 108 may be
ejected outward continuously.
[0057] 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.
