Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
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.
2. Description of Related Art
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.
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.
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.
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

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.
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.

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).
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).
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).
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).
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).
The limiting member (30) is mounted securely around the barrel (1A) and has a bracket, a bar (303) and a limit (301).
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).
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.
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, 302 a, 302 b). 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 (302 a) is concave. With reference to FIG. 5, a third variant of the limiting surface (302 c) is convex.
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.
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.
