[Detailed description of the device]

[0001]

TECHNICAL FIELD This invention relates to a toy gun. Specifically, it relates to a toy gun that uses a gas such as air or carbon dioxide to shoot a bullet.

[0002]

2. Description of the Related Art As a conventional toy gun that uses gas,
Various things are known.

[0003]

[Problems to be Solved by the Invention] However, the conventional toy gun has a problem that there is no impact at the time of firing and the sense of reality is lacking.

Further, in the conventional example in which the cocking head is installed at the rear end of the barrel in order to give a sense of presence, there is a problem that the cocking head needs to be contracted by hand each time a bullet is fired. And with conventional toy guns, there is a problem that rapid and continuous fires are difficult because it is necessary to fire each time.

[0005]

[Means for Solving the Problems]

[0006] A magazine for accommodating bullets and urging the accommodated bullets upward, a chamber installed in the barrel for opening one end of the magazine, a barrel installed in the muzzle from the chamber, and a barrel installed below the barrel. A cylinder storage part for storing a gas-filled cylinder, an air chamber communicating with the gas outlet of the cylinder, a hammer bar storage chamber installed parallel to the barrel behind the barrel from the chamber, and the chamber and hammer. A valve installed between the bar storage chamber, a hammer bar biased toward the muzzle side, a cocking head attached to the rear end of the hammer bar, and a hammer bar storage chamber parallel to the top of the hammer bar storage chamber. Installed cylinder storage chamber and piston guide installed in the cylinder storage chamber parallel to the cylinder storage chamber and urged toward the muzzle direction and the rear end attached to the cocking head , The tip of the cylinder protrudes into the chamber and has a piston locking part at the rear, which is slidable in the cylinder accommodating chamber, and can freely slide on the muzzle side of the piston guide while the movement toward the muzzle side is restricted by the piston guide. Attached to the muzzle side and a piston sear locking part is provided at the rear end and is slidable while contacting the inner surface of the cylinder, and the tip projects into the cylinder storage chamber and is urged toward the rear side. Piston sear, a trigger that is biased toward the muzzle side, a trigger bar that is installed at the rear of the trigger and is moved rearward by moving the trigger backward, and one end contacts the trigger bar and is biased toward the muzzle side. In addition, the cylinder storage chamber side end part is in contact with the piston sear and consists of a second sear rotatably attached to the barrel at the middle part,

[0007] to provide.

[0008]

[Function] The cylinder fills the air chamber with gas. The valve is pushed by the pressure of the gas to shut off the air chamber and the hammer bar storage chamber.

Then, the cocking head is pulled backward.
Then, the piston guide fixed to the cocking head and the hammer bar retreat in the direction away from the muzzle. The piston guide moves the piston rearward as it retreats. The piston retracts the cylinder as it retracts.

When the cylinder retracts, the bullet rises in the chamber.

Next, the cocking head is advanced to return it to its original position. Then, the piston guide pushes the cylinder forward. Although the piston moves forward, that is, toward the muzzle side, the piston sear locking portion is locked to the piston sear and is prevented from moving toward the muzzle side.

When the trigger is pulled rearward, the trigger bar also moves, pushing and rotating the contact end of the second shear with the trigger bar rearward. Due to the rotation of the second shear, the piston shear, which has been blocked from rotation by the contacting second shear, moves to the muzzle side and unlocks the piston. Then, the piston is accelerated and moves to the muzzle side. The piston sear is released from the engagement with the piston and returns to its original state.

When the piston moves forward, the air in the cylinder is compressed and discharged into the barrel. The released air accelerates the bullet in the barrel. When the piston reaches the front, the piston guide moves forward together. When the piston guide moves forward, the cocking head attached to the piston guide advances. When the cocking head advances, the hammer bar attached to the cocking head also advances.

The hammer bar hits the valve and advances toward the muzzle side. Then, the valve breaks the cutoff between the air chamber and the hammer bar storage chamber, and the gas in the air chamber is released into the hammer bar storage chamber.

Then, the gas released into the hammer bar storage chamber pushes the hammer bar rearward and retracts the cocking head. Then, the piston guide attached to the cocking head and the piston in contact with the piston guide are also retracted. After that, the cocking head automatically advances and retracts each time the trigger is retracted.

Reference numeral 53 is a piston sear. The piston sear 53 has a tip protruding from the inside of the cylinder housing chamber 41, and is urged by a piston sear spring 54 toward the rear side of the toy gun.

Reference numeral 61 is a trigger. Trigger 61
Is urged toward the muzzle 16 side by the trigger spring 62.

Reference numeral 63 is a trigger bar. The trigger bar 63 is installed at the rear of the trigger 61 and
It is moved to the rear by moving it to the rear.

Reference numeral 71 is a second shear. The second shear 71 has one end in contact with the trigger bar 63 and is biased toward the muzzle 16 side by the second shear spring 72. An end of the second sear 71 on the cylinder housing chamber 41 side is in contact with the piston sear 53, and is rotatably attached to the barrel by a rotary shaft 73 provided in the middle.

Next, the operation of the embodiment will be described. The cylinder 22 fills the air chamber 24 with carbon dioxide gas. The valve 26 is pushed backward by the pressure of the gas and the air chamber 2
4 and the hammer bar storage chamber 25 are shut off.

Then, the cocking head 34 is pulled backward. Then, the piston guide 42 fixed to the cocking head 34 and the hammer bar 31 retreat in the direction away from the muzzle 16. The piston guide 42 moves the piston 51 rearward as it retreats. Piston 51
Causes the cylinder 44 to move backward with the backward movement.

When the cylinder 44 retracts, the bullet 12 rises in the chamber 14.

Then, the cocking head 34 is advanced to return it to its original position. Then, the piston guide 42 pushes the cylinder 44 to move it forward. The piston 51 moves forward, that is, to the muzzle 16 side, but the piston sear locking portion 52 is locked to the piston sear 53 and is prevented from moving to the muzzle side 16.

When the trigger 61 is pulled backward, the trigger bar 63 also moves, pushing and rotating the contact end of the second shear 72 with the trigger bar 63 backward. Due to the rotation of the second sear 72, the piston sear 53, which has been prevented from rotating by the contacting second sear 72, moves to the muzzle 16 side and unlocks the piston 51. Then, the piston 51 is accelerated and moves toward the muzzle 16 side. The piston sear 53 is released from the engagement with the piston 51 and returns to its original state.

When the piston 51 moves forward, the cylinder 4
The air in 4 is discharged into the barrel 15 while being compressed.
The released air accelerates the bullet 12 in the barrel 15. The piston 51 moves the piston guide 42 forward together when the piston 51 reaches the front. When the piston guide 42 moves forward, the cocking head 34 attached to the piston guide 42 advances. When the cocking head 34 moves forward, the hammer bar 31 attached to the cocking head 34 also moves forward.

The hammer bar 31 hits the valve 26 and advances toward the muzzle 16 side. Then, the shutoff of the air chamber 24 and the hammer bar storage chamber 25 by the valve 26 is broken, and the air chamber 2
The gas in 4 is discharged into the hammer bar storage chamber 25.

Then, the gas released into the hammer bar storage chamber 25 pushes the hammer bar 31 rearward and retracts the cocking head 34. Then, the piston guide 42 attached to the cocking head 34 and the piston 51 in contact with the piston guide 42 are also retracted. After that,
Each time the trigger 61 is retracted, the cocking head 34
Automatically moves back and forth, and each time the trigger 61 is pulled, it gives a realistic impact.

[0039]

[Effects of the Invention] Therefore, the present invention provides a toy gun that is capable of rapid and continuous fire and that automatically gives an impact after the second trigger retreat.
