Bullet-loading structure of toy gun
Abstract
In a toy gun with a bullet-loading structure, a cylinder, a
piston, a final gear, and a pull rod are mounted in a gun body. The
piston and the pull rod are driven by the rotation of the final
gear. An actuation time of the pull rod is later than that of the
piston to enable the piston to suck a lot amount of gas before the
loading of the bullet, thereby preventing a gun tunnel from being
blocked by the raised bullet and providing the simulated recoil
effect of real shooting so as to promote the shooting performance
of the toy gun.

Description
FIELD OF THE INVENTION
[0001] The present invention relates to a bullet-loading structure
of a toy gun, and more particularly to a bullet-loading structure,
wherein an actuation time of the pull rod is later than that of the
piston so as to prevent a gun tunnel from being blocked by the
raised bullet, thereby providing the simulated recoil effect, which
simulates the real shooting, so as to promote the shooting
performance of the toy gun.
BACKGROUND OF THE INVENTION
[0002] Referring to FIG. 9 through FIG. 11, wherein FIG. 9 and FIG.
10 are cross-sectional views showing the bullet-loading states of
the conventional toy gun. This conventional toy gun utilizes a high
torque motor to drive a final gear 20 for further driving a
compressible spring 50 and a piston 40 having a rack 30. The
compressible spring 50 is compressed when the piston 40 is shifted
backward. At the same time, a certain amount of gas is sucked into
a cylinder 60 for being compressed. When a tooth-shaped arc edge
201 is disengaged from the rack 30 located on the lower portion of
the piston 40, the bullet 10 is strongly pushed out via a
bullet-pushing outlet 80 by the piston 40, which utilizes the push
force provided by the released compressible spring 50.
[0003] However, a slide block 203 located on the rear end of a pull
rod 70 has already been touched by a protrudent pillar 202 mounted
vertically on one side of the final gear 20 before the suction of
the gas into the cylinder 60. With the rotation of the final gear
20, the bullet-pushing outlet 80 of the pull rod 70 is shifted
backward for loading the bullet. At the moment, the bullet-pushing
outlet 80 is jammed by the bullet 10. As a result, the gas suction
is affected. As shown in FIG. 11, a cross-shaped trench 801 is too
small to increase the gas-suction amount even if it has been formed
on the front end of the bullet-pushing outlet 80 for gas suction.
Besides, the sucked gas is more insufficient since the piston 40 is
pushed back rapidly. In addition, the centralization of the
exhausted gas is also affected by the formation of the cross-shaped
trench 801, resulting in the reduced shooting performance and the
lack of recoil effect in real shooting.
SUMMARY OF THE INVENTION
[0004] Whereas the foregoing description, the present inventor
makes diligent studies in providing an improved structure so as to
overcome the conventional problems.
[0005] It is a main object of the present invention to provide a
bullet-loading structure, wherein an actuation time of the pull rod
is later than that of the piston to enable the piston to suck a lot
amount of gas by using the maximum aperture of the bullet-pushing
outlet, thereby preventing a gun tunnel from being blocked by the
raised bullet and providing the simulated recoil effect, which
simulates the real shooting, so as to improve the shooting
performance of the toy gun.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] The above-mentioned features and advantages of this
invention, and the manner of attaining them, will become more
apparent and the invention will be better understood by reference
to the following description of embodiments of the invention taken
in conjunction with the drawings.
[0018] Referring to FIG. 1 and FIG. 2, a piston 3 is slidable in a
cylinder 2 in a gun body 1 of the present invention and a
compressible spring 4 is located between the piston 3 and a rear
end of the gun body 1. The backward shifting of the piston 3 in the
cylinder 2 causes the suction of the gas. Besides, the gas is
compressed immediately when the piston 3 is shifted forward by the
resilience force provided by the recovered compressible spring 4,
which is compressed previously, such that the compressed gas is
exhausted from a gas outlet 21 of the cylinder 2 for shooting a
bullet.
[0019] The power for shifting the piston 3 backward is supplied in
accordance with the following description. A rack 31, which is
mounted on the lower edge of the piston 3, is engaged with a final
gear 5. The final gear 5 is a semi-gear and comprises a releasing
arc edge 51 and a tooth-shaped arc edge 52, wherein an internal
gear 53, which is mounted on one side of the final gear 5, can be
driven by a motor (not shown) via a gear set. In addition, a
protrudent pillar 54 is mounted vertically on the other side of the
final gear 5 between a start end 55 and a stop end 56 of the
tooth-shaped arc edge 52. Detailedly speaking, the protrudent
pillar 54 is located near the center portion of the tooth-shaped
arc edge 52 deviant toward the stop end 56. In other words, with
respect to an axis of the final gear 5, an included angle between
the protrudent pillar 54 and the start end 55 is .theta.1 and an
included angle between the protrudent pillar 54 and the stop end 56
is .theta.2, wherein .theta.1 is larger than .theta.2, as shown in
FIG. 8.
[0020] Besides, a curved pull rod 6 located on the bottom of the
cylinder 2 is provided for controlling the loading of the bullet,
wherein a front end of the pull rod 6 is locked to a bullet-pushing
outlet 7, which is sleeved to a gas outlet 21, wherein the pull rod
6 is held in a gun tunnel of a barrel 8 and further comprises a
slide block 61 on the rear end thereof and on one side of the
protrudent pillar 54 of the final gear 5. Besides, the pull rod 6
is securely coupled to the gun body 1 via a recoil spring 9. The
slide block 61 has a bevel edge 611 having an irregular curve. When
the final gear 5 is in operation, the protrudent pillar 54 slides
along the bevel edge 611 of the slide block 61 to push the pull rod
6 backward until the protrudent pillar 54 reaches a rear end of the
bevel edge 611. By using the curve design of the bevel edge 611,
the force applied by the protrudent pillar 54 for pushing the pull
rod 6 can be reduced. Lastly, the pull rod 6 returns to its
previous position by using the resilience force of the recoil
spring 9.
[0021] Referring further to FIG. 3 through FIG. 8, as shown in FIG.
3, in the initial state, a magazine (now shown) can push the bullet
10 upward to block it by the bottom of the bullet-pushing outlet 7.
At the same time, the final gear 5 is engaged with the rack 31
located on the lower portion of the piston 3. As shown in FIG. 4, a
torque motor is actuated to rotate the final gear 5
counter-clockwise. At the same time, the piston 3 is also driven to
shift back for gas suction.
[0022] As shown in FIG. 5, when the final gear 5 is rotated to the
middle region between the start end 55 and the final end 56 after
it is operated for a certain period of time, as shown in FIG. 8,
the bevel edge 611 of the slide block 61 is touched by the
protrudent pillar 54 so as to make sure that the gas can be sucked
into the piston 3 fully before the loading of the bullet 10. After
the continuous operation of the final gear 5, the protrudent pillar
54 slides along the bevel edge 611 to push the pull rod 6 backward,
whereby the bullet 10 is released from the blocking of the
bullet-pushing outlet 7 and thus raised to be located in the barrel
8.
[0023] As shown in FIG. 6, when the protrudent pillar 54 slides to
the rear end of the slide block 61, the force applied by the
protrudent pillar 54 for pushing the pull rod 6 can be reduced by
using the curve design of the bevel edge 611 such that the pull rod
6 is shifted forward by the recovered resilience force of the
recoil spring 9 (referring to FIG. 1), whereby another bullet 10'
is blocked by the bullet-pushing outlet 7 to wait for next shooting
procedure. After that, as shown in FIG. 7, when the final gear 5 is
rotated to the releasing arc edge 51 for being disengaged from the
rack 31 of the piston 3, the piston 3 is shifted forward by using
the force of the compressible spring 4 to exhaust the gas in the
cylinder 2 for pushing the bullet 10 in the barrel 8 to the
outside.
[0024] As described above, in the present invention, the actuation
time of the pull rod is later than that of the piston so as to form
a time difference in the displacement of the bullet-pushing outlet
and the piston. In other words, the process time spent by the
tooth-shaped arc edge in engaging with the rack of the piston is
larger than the process time spent by the protrudent pillar in
sliding along the slide block. Besides, the bullet-loading process
is completed during the process of sucking the gas, whereby the
piston can suck a lot amount of gas by using the maximum aperture
of the bullet-pushing outlet and can shift the bullet-pushing
outlet by using the protrudent pillar for loading the bullet so as
to prevent the gun tunnel of the barrel from being blocked by the
raised bullet. As a result, the gas-suction capacity of the piston
is increased, thereby promoting the shooting performance of the toy
gun by providing the simulated recoil effect of real shooting.
[0025] While the preferred embodiment of the invention are set
forth for the purpose of disclosure, modifications of the disclosed
embodiment of the invention as well as other embodiments thereof
may occur to those skilled in the art. Accordingly, the appended
claims are intended to cover all embodiments, which do not depart
from the spirit and scope of the invention.
