Abstract

A bullet feed portion reciprocates and is positioned in a firing position where a bullet housing chamber is opposed to a bullet feed port, and in a non-firing position where the bullet feed port is closed. A gas flow path guides compressed gas to the bullet feed port in an inner barrel. A valve is biased to close the gas flow path. A firing action mechanism has a movable body that can be freely reciprocated along the inner barrel. The firing action mechanism moves the bullet feed portion to a firing position and moves the valve to a non-biasing direction. A power transmission unit transforms motor force into the locomotion of a movable body. When trigger is pulled, the motor moves the movable body toward the bullet feed port to feed a bullet into the bullet feed portion, and actuate the firing action mechanism.

Abstract

A trigger sear is placed between a trigger and a bolt sear. The engagement between the bolt sear and a bolt is removed by pulling the trigger. The bolt makes reciprocating motion in the back and forth direction of the toy gun. While it reciprocates once, the bolt opens and closes a valve portion and fires off a bullet B. When the trigger is pulled, a stopper pawl and a driving pawl are engaged with a control plate having a ratchet gear structure. In conjunction with the reciprocating motion of the bolt, the driving pawl rotates and displaces the control plate in a forward direction. When the toy gun fires a predetermined number of bullets B, a sear bar is displaced. The sear bar moves the trigger sear and causes it to break away from the bolt sear.

Abstract

The structure of air guns with a conventional blowback mechanism was complicated because they had a hammer, sear, trigger bar, bullet supply nozzle, bullet supply nozzle link, etc. These members operated every time when a bullet was shot resulting in the members being readily worn, with failure often occurring as well as problems with durability. In order to solve these problems, the valve body has a valve body air chamber sealed to contain the compressed gas supplied from the compressed gas source, and has a discharge valve which can move in a longitudinal direction. The discharge valve has a valve through hole that passes completely from the muzzle to the gun rear end direction, and a gas supply port that can open and close the valve body air chamber and valve through hole by the movement of the discharge valve in the longitudinal direction. Retreat of the inner barrel opens the gas supply port of the discharge valve to shoot a bullet and perform blowback.

Abstract

An air gun includes a retainer pivotably connected inside the air gun and having a bullet abutment part that pivots into and out of a bullet-receiving chamber. The retainer is resiliently biased to pivot in a forward direction so that the bullet abutment part is urged into the bullet-receiving chamber. In a trigger rest position, a hollow inner barrel prevents a bullet and the bullet abutment part from entering into the bullet-receiving chamber. Upon pulling the trigger, the inner barrel moves in a forward direction to permit the bullet and the bullet abutment part to enter the bullet-receiving chamber where the bullet abutment part contacts and retains the bullet therein. Upon pulling the trigger further, the inner barrel moves in a rearward direction to capture the bullet therein while causing the retainer to pivot in the rearward direction to thereby move the bullet abutment part out of the bullet-receiving chamber.

There has been a problem that a projected part of a rear part of a pellet gets stuck with an end side of an attachment wall and rotation is interrupted when a rotary clip moves from a hit pin concave to an end side (i.e., attachment wall) of a magazine main body if the rear end of a pellet in a bore projects from a bore. In order to resolve the problem, there is proposed a magazine main body 1 and a magazine main body 1 having a rotary clip 2 rotatably attached to a rotary clip attachment part 3 of a magazine main body 1 characterized in that a clip opposing wall surface 33 of an attachment wall 34 of a clip opposing wall surface 33 gradually moves away from a cylindrical end surface of opposing rotary clip 2 towards an end side 31 of an attachment wall 34 within a range 35 of a rotational opposing surface positioned between a hit pin concave 32 and a side surface part 10 in the rotational direction of rotary clip 2.
