Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a loading assembly, and
more particularly to a bullet-loading assembly for a toy gun that
has a bullet chamber and controls a single ball bullet to be loaded
into the bullet chamber. The bullet-loading assembly prevents more
than one ball bullet from being inadvertently loaded into the
bullet chamber.
[0003] 2. Description of Related Art
[0004] A conventional toy gun has a handgrip, a barrel, a trigger,
a handgrip, a bolt, a hammer and a loading assembly and may be
loaded with ball bullets (BBs) and installed with a high pressure
air bottle. When firing the toy gun, a player triggers the toy gun,
the hammer is activated to pivot backwards and then forwards to hit
and push the bolt. Then high pressure air in the air bottle flows
rapidly into the bolt and impacts one BB in front of the bolt to
jet the BB through the barrel out of the toy gun.
[0005] The loading assembly is mounted in the handgrip adjacent to
the barrel and has a controlling element and a spring. The
controlling element is movable in response to the hammer, controls
the feeding of the BBs and allows only one BB to pass into and stay
in the barrel for firing the toy gun. The spring biases the
controlling element to press against one BB and provide the
resilient force to recover the controlling element back to its
original position after the toy gun is trigger.
[0006] However, after using the toy gun frequently and repeatedly,
the spring is fatigued and cannot timely recover the position of
the controlling element, which causes more than two BBs
inadvertently loaded into the barrel. When triggered with BBs, the
toy gun may be jammed and damaged.
[0007] To overcome the shortcomings, the present invention provides
a bullet-loading assembly for a toy gun to mitigate or obviate the
aforementioned problems.
SUMMARY OF THE INVENTION
[0008] The main objective of the invention is to provide a
bullet-loading assembly for a toy gun that has a bullet chamber and
controls a single ball bullet to be loaded into the bullet chamber
every time after the toy gun is triggered. The bullet-loading
assembly prevents more than one ball bullet from being
inadvertently loaded into the bullet chamber.
[0009] A bullet-loading assembly in accordance with the present
invention is mounted on a toy gun. The toy gun has a body and a
triggering assembly. The body has a handgrip, an outer chamber, a
seal, a bullet chamber, a guiding slot and a bottle chamber. The
triggering assembly has a bolt, a trigger, a hammer, a linking bar
and a link. The bullet-loading assembly has a barrel, a bullet
passageway, a magazine and a limiting member. The barrel is mounted
on the body and has a rear end and a bore. The bullet passageway is
defined through the handgrip and is located adjacent to the barrel.
The limiting member is mounted securely around the barrel and has a
limit formed located in front of the axis of the bullet passageway
and presses against an uppermost ball bullet in the bullet
passageway to prevent more than one ball bullet from entering the
bullet chamber.

[0020] The handgrip (10) is mounted on the body (1).
[0021] The outer chamber (12) is defined in the body (1) above the
handgrip (10).
[0022] The seal (13) is mounted in the outer chamber (12).
[0023] The bullet chamber (11) is defined in the body (1) in front
of the outer chamber (12).
[0024] The guiding slot (14) is defined in the body (1) above the
bullet chamber (11).
[0025] The bottle chamber (16) is defined in the handgrip (10A) and
communicates with the outer chamber (12) and may receive the air
bottle.
[0026] The discharge member (17) is mounted in the bottle chamber
(16) and may pressing against the outlet valve on the air bottle to
discharge high-pressure air in the air bottle into the outer
chamber (12).
[0027] The triggering assembly (2) is mounted in the body (1) and
has a bolt (20), a trigger (21), a hammer (24), a linking bar (23)
and a link (22).
[0028] The bolt (20) is mounted slidably in the outer chamber (12),
selectively abuts the seal (13) hermetically, selectively
communicates with the outer chamber (12) and has a front end, a
rear end, an channel (201) and two air passages (202). The channel
(201) is defined axially in the front end of the bolt (20),
communicates with the bullet chamber (11) and selectively
communicates with the outer chamber (12). The air passages (202)
are defined transversely through the bolt (20), communicate with
the channel (201) and are selectively sealed by the seal (13) to
hermetically isolate the channel (201) from the outer chamber (12).
When the bolt (20) moves forward and separates from the seal (13),
the air passages (202) are unsealed and the channel (201)
communicates with the outer chamber (12) to allow high-pressure air
in the air bottle (5) to pass into the channel (201).
[0029] The trigger (21) is mounted pivotally in the body (1) and
has a connecting end and a recoiling element. The recoiling is
mounted on the body (1) and biases the trigger in an un-pulled
position and may be a torsion spring.
[0030] The hammer (24) is mounted pivotally on the body (1) and
selectively hits the rear end of the bolt (20) to move the bolt
(20) forwards.
[0031] The linking bar (23) connects pivotally to the trigger (21)
and the hammer (24) so that the hammer pivots backwards and then
pivots fast forwards to hit the bolt (20) when the trigger (21) is
pulled to pivot backwards.
[0032] The link (22) is Y-shaped, is mounted pivotally in the body
(1) and has a lower connecting section (220), two opposite upper
prongs (221) and two slide pivots (222). The lower connection
section (220) connects pivotally to the connecting end of the
trigger (21) so that pulling the trigger (21) pivots the lower
connection section (220) forwards. The upper prongs (221) are
formed on and protrude longitudinally form the lower connection
section (220) and pivots backwards when the lower connection
section (220) pivots forwards. The slide pivots (222) are formed
respectively on and protrudes transversely inwards from the prongs
(221).
[0033] The bullet-loading assembly (3) in accordance with the
present invention is mounted in the body (1) and has a barrel (1A),
a bullet passageway (15), a magazine (31) and a limiting member
(30).
[0034] The barrel (1A) is mounted on the body (1) in front of the
bullet chamber 3 (11), is aligned with and in front of the bolt
(20) and has a rear end and a bore. The bore is defined axially
through the barrel (1A), communicates with the bullet chamber
(11).
[0035] The bullet passageway (15) is defined through the handgrip
(10A), is located adjacent to the barrel (1A), communicates with
the bore of the barrel (1A) and has an axis (C).
[0036] The magazine (31) is mounted detachably in the handgrip (10)
has a base (310), a follower (311) and a spring (312). The base
(310) is mounted 11 detachably on the handgrip (10) and extends in
the bullet passageway (15). The follower (311) is mounted slidably
in the bullet passageway (15) above the base 13 (310) and presses
against the BBs (4) to set the uppermost BB (4) into the bullet 14
chamber (15) of the body (1). The spring (312) is mounted between
the base (310) and the follower (311) to bias the follower (311)
towards the bullet chamber (15).
[0037] The limiting member (30) is mounted securely around the
barrel (1A) and has a bracket, a bar (303) and a limit (301).
[0038] The bracket is mounted securely around the barrel (1A) and
has two opposite sides, two pivot slots (305) and two C-clasps
(306). The pivot slots (305) are defined in the sides of the
bracket and pivotally engage respectively with the pivots (222) on
the prongs (221) of the link (22) so that the trigger (21) drives
the barrel (1A) and the limiting member (30) to move backwards
through the link (22). The C-clasps (306) are mounted securely
around the barrel (1A) and locates the bracket between the C-clasp
(306) to prevent the bracket from slipping on the barrel (1A).
[0039] The bar (303) is longitudinal, is formed on and protrudes
backwards from the bracket, is capable of sliding linearly in the
guiding slot (14) in the body (1) and has a rear end.
[0040] The limit (301) is formed on the rear end of the bar (303),
projects out from the rear end of the barrel (1A), is located in
front of the axis (C) of the bullet passageway (15) and presses
against the uppermost BB (4). The limit (301) has a limiting
surface (302, 302a, 302b). The limiting surface (302) is defined on
the limit (301), faces obliquely downward to the bullet passageway
(15) and presses against and set the uppermost BB (4) in the bullet
chamber (1) to prevent from BBs (4) from inadvertently passing to
the bullet chamber (11). With reference to FIG. 3, a first variant
of the limiting surface (302) is fat. With reference to FIG. 4, a
second variant of the limiting surface (302a) is concave. With
reference to FIG. 5, a third variant of the limiting surface (302c)
is convex.
[0041] With reference to FIG. 6, when a user pulls the trigger
(21), the barrel (1A) and the limiting member (30) moves back. The
rear end of the barrel (1A) engages with the front end of the bolt
(20) and receives the uppermost BB (4). Simultaneously, the hammer
(24) is driven by the trigger (21) through the link bar (23) to
knock bolt (20) away from the seal (13) so that the air passages
(202) are unsealed. The outer chamber (12) communicates with the
channel (201) in the bolt (20) so that the high-pressure air in the
air bottle (5) flow fast through the outer chamber (12), the air
passages (13) into the channel (201) to jet the uppermost BB (4)
out of the toy gun. When the trigger (21) is released, the
recoiling element biases the trigger (21) backwards to the
un-pulled position.
[0042] The limiting member (30) of the bullet-loading assembly
controls the uppermost BB (4) to be loaded into the bullet chamber
(11) and prevents other BBs (4) from being loaded inadvertently
into the bullet chamber (11). Therefore, toy gun are loaded
precisely with the BBs (4) without being jammed or damaged.
[0043] Even though numerous characteristics and advantages of the
present invention have been set forth in the foregoing description,
together with details of the structure and function of the
invention, the disclosure is illustrative only. Changes may be made
in the details, especially in matters of shape, size, and
arrangement of parts within the principles of the invention to the
full extent indicated by the broad general meaning of the terms in
