DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air sports gun, and more particularly, to an air sports gun that fires bullets with compressed gas such as air, chlorofluorocarbon, or carbon dioxide supplied from a gas cylinder.

[0002]

2. Description of the Related Art Conventionally, for example, an air sports gun shown in FIG. 32 is known as an automatic air sports gun using compressed gas such as air, chlorofluorocarbon or carbon dioxide.

[0003] That is, 101 is an automatic air sports gun. Automatic air sports gun 1
01 is operated by pulling the trigger 102 and the hammer 103
Rotates in the direction of the arrow and presses the valve pin. When the valve pin 104 is pressed, the compressed gas 105 is supplied to the valve 1.
06 and flows into the slide 107 side. The bullet 109 supported by the rubber chamber 108 in the valve 109
Is moved to the rear of the gun, the compressed gas 105 flowing into the slide 107 flows into the bullet W side in the rubber chamber 108 and pushes out the bullet W, and the outer barrel 110
And fires from the muzzle 111. The bullet W supported in the rubber chamber 108 keeps the valve 109 moved rearward of the gun 101 against the urging force of the valve spring 112 until the bullet W is fired by the compressed gas 105. After the bullet W is fired, the valve 109 is pushed back to the muzzle 111 side by the valve spring 112, and stops the outflow of the compressed gas 105 to the muzzle 111 side. Then, the compressed gas 105 flows into the slide 107 and the slide 1
07 was moved to the rear of the gun 101, the next shot was loaded, the hammer 103 was laid down, etc., and the next shot was prepared and the bullet was fired. However, in order to supply the compressed gas 105 to the projectile W to be fired, the projectile W to be fired is used by the valve 1 against the urging force of the valve spring 112.
09 must be moved behind gun 101,
The holding force of the rubber chamber 108 holding the bullet W must be strong, and not only extra pressure is required to resist the holding force for firing the bullet W, but also the rubber chamber 108 deteriorates due to long-term use. Occurs, the gripping force of the bullet W decreases, the set position of the bullet W in the rubber chamber 108 shifts, and the valve 109 or the slide 10
There is a problem that the position of 7 and the like and the operation timing are shifted and there is a fear that the operation or more may occur. Further, when the deterioration proceeds, the action direction of the holding force between the rubber chamber 108 and the supported bullet W is substantially perpendicular to the firing direction,
Cannot withstand the urging force of the valve spring 112,
The bullet W moves in the direction of the muzzle 111 and the valve 109 is closed, so that the compressed gas 105 does not flow in the direction of the rubber chamber 108, and there is a fear that the bullet W may become unusable.

[Problems to be solved by the invention]
Patent Application No. 035941 entitled "Automatic Air Sports Gun Launching Mechanism and Automatic Strong Air Sports Gun Using a Launching Mechanism", in which bullets are sequentially loaded with compressed gas, and the user pulls a trigger to release the bullet. A bullet can be fired and the next round can be loaded. However, there is a problem that the next round cannot be fired unless the trigger is returned once and the trigger is pulled again. Further, in the configuration of the above-described conventional example, when the slide moves to the rear of the gun and further moves to the muzzle side by the biasing force, the bullet is loaded into the loading packing 208, so that the use is performed when the bullet remains in the magazine. When stopped, the last loaded bullet remains loaded at the barrel end, which has the problem that the loaded bullet must be removed. Furthermore, when the hammer valve 231 is opened, the valve stopper 240 immediately moves so as to maintain the open state of the hammer valve 231, so that the compressed gas storage part 226 and the first air chamber 229 are filled with the compressed gas. When the trigger 247 is accidentally pulled when not in operation, the compressed gas is replenished in this state when there is no compressed gas. When the hammer valve 231 is open, the compressed gas moves to the second air chamber 219 and the bullet W is discharged. There was a problem of being fired. Therefore, in the present invention, the trigger 24
By keeping the state where 7 is pulled, the structure that can load the next bullet in sequence and fire the next bullet is possible, enabling continuous firing that shoots bullets continuously, and pulling the trigger causes the bullet to be released With a structure to be loaded at the end,
An object of the present invention is to provide an air sports gun in which bullets are not accidentally fired when refilling compressed gas.

An automatic air sports gun, wherein a bolt, a cylinder block, a hammer, a hammer shear, a trigger shear, and a bolt shear are included in the gun body;

The above-mentioned problem is solved by providing the above, and the operation is as follows.

That is, in a normal state, the pressing protrusion of the cylinder block is pressing the hammer shear, and the compressed gas storage portion and the first air chamber are filled with the compressed gas.

Pull the bolt from the muzzle side to the rear end of the gun. The bolt begins to move backward against the biasing force. The cylinder block provided in the bolt and the nozzle block having one end inserted into the cylinder block are also moved rearward together with the bolt. When the muzzle-side tip of the nozzle block moves rearward from the magazine opening of the magazine, the bullet is supplied into the chamber by the urging force of the magazine. When the bolt is further moved to the rear end of the gun, the rear end of the cylinder block comes into contact with the hammer, and the hammer is rotated to the rear end of the gun. At the same time, the pressing of the hammer shear by the pressing protrusion of the cylinder block is released, and the hammer is locked with the hammer and the rotated hammer is locked. Further, the bolt shear is located on the muzzle side from the muzzle-side tip of the bolt and rotates upward. When the movement of the bolt to the rear end is completed, the bolt starts to return to the muzzle side again by the urging force, but is stopped by the movement to the muzzle side by the bolt shear.

Then, the user pulls the trigger section. Then, the trigger shear rotates in conjunction with the trigger portion, and the shear locking projection of the trigger shear presses the intermediate portion of the bolt shear. The pressed bolt shear is rotated downward, the locking of the bolt locking portion of the bolt shear and the bolt is released, and the bolt moves toward the muzzle. When the bolt moves toward the muzzle, the cylinder block and nozzle block also move to the muzzle side, and the muzzle end of the nozzle block pushes the bullet in the muzzle, and when the movement to the muzzle side is completed, the bullet moves to the rear end of the barrel of the barrel. Part of the chamber. or,
The hammer shear is pressed by the pressing protrusion of the moved cylinder block to release the engagement with the hammer. Then, the hammer rotates toward the muzzle. The hammer rotates toward the muzzle and presses the valve rod of the hammer valve.
Then, the hammer valve is opened, the compressed gas moves from the first air chamber to the second air chamber, moves toward the muzzle side from the vent hole side of the nozzle block, and a bullet is fired. Next, the nozzle closes the bullet hole side vent hole and opens the cylinder block side vent hole. Then, the compressed gas flows into the cylinder block side ventilation hole, and moves the cylinder block toward the rear end of the gun. When the cylinder block slightly moves toward the rear end of the gun, the stopper guide groove is positioned above the valve stopper, and the hammer valve is opened, so that the valve stopper moves upward to maintain the valve open state.

The hammer valve is opened, and the compressed gas in the first air chamber flows into the nozzle block from the intake / exhaust port of the second air chamber via the hammer valve. The inflowing compressed gas flows into the muzzle side since the ventilation hole on the cylinder block side is closed by the closing portion of the valve. The bullet loaded in the barrel end is pushed by the inflowing compressed gas, moves in the barrel, and is fired from the muzzle to the outside. The bullet is fired and the muzzle side is opened, and the pressure of the compressed gas temporarily drops. Then, the valve is moved toward the muzzle side against the urging force of the valve due to the negative pressure after the bullet is fired. By the valve moved to the muzzle side, the bullet hole side ventilation hole of the nozzle block is closed by the intermediate part, the cylinder block side ventilation hole is opened, and the compressed gas flows into the cylinder block side ventilation hole. The pressure between the cylinder block and the nozzle block is increased by the inflowing compressed gas, and the cylinder block starts to move toward the rear end of the gun,
The bolt that houses the cylinder block also starts moving toward the rear end of the gun.

In the process of moving the bolt, the cylinder block, and the nozzle block toward the rear end of the gun, when the locking projection at the intermediate portion of the bolt is locked with the nozzle block, the nozzle block also starts moving toward the rear end of the gun. Further, the rear end of the cylinder block contacts the hammer, and the hammer starts rotating toward the rear end of the gun against the urging force. In addition, the stopper guide groove of the cylinder block is displaced from the valve stopper position, and the lock between the valve rod of the hammer valve and the valve stopper is released, and the hammer valve is closed. The hammer valve is closed and the flow of compressed gas ends, but the movement toward the rear end of the gun continues due to inertia, the volume in the cylinder block increases, the gas pressure in the cylinder block decreases, and The valve opens the bullet hole side ventilation hole by the force. When the sliding of the bolt continues and the loading end of the nozzle block moves rearward from the opening of the loading port of the magazine, the bullet is supplied to the loading port by the urging force of the magazine. Further, the sliding of the bolt continues, the bolt reaches the rearmost end, and starts sliding toward the muzzle side again by the urging force. At this time, the hammer is locked with the hammer shear against the urging force. When the bolt moves to the muzzle side, the bolt locks with the bolt shear, and the movement of the bolt to the muzzle side ends. In this state, pull the trigger to fire the second bullet. Then, the locking of the bolt with the bolt shear is released,
The bolt, cylinder block, and nozzle block move to the muzzle side again, and in the process of movement, the muzzle end of the nozzle block pushes the bullet supplied to the muzzle, and at the end of sliding to the muzzle side, Two bullets are loaded in the chamber. Then, similarly to the firing of the first bullet, the lock of the hammer is released, the hammer opens the hammer valve, and the second bullet is fired by the compressed gas. Also, if the trigger is pulled after the first shot is fired, the bolt shear does not lock the muzzle end of the bolt, so after the first shot, the next shot is fired until the trigger is released. Is repeated, and continuous firing is possible. Furthermore, when the second bullet is not fired without pulling the trigger, the muzzle end of the nozzle block does not move by pushing the second bullet toward the muzzle side, and the second bullet is not fired, and the magazine Stays inside.

Next, the operation of this embodiment will be described with reference to the drawings. The operation state will be described in the case where the user continuously fires (continuously fires) a bullet. It is assumed that the bullet W is already loaded in the magazine 2. To load the first bullet W, the user slides the bolt 9 in the direction A. Then, Figure 1
4 to 4, the bolt 9 moves in the A direction, and the fixed cylinder block 13 and nozzle block 17 also move in the A direction. As the movement further proceeds, the nozzle block 17 moves in the direction A from the loading port 4 above the magazine 2 in the chamber 5 and the first bullet W moves upward from the magazine 2 and is supplied to the loading port 4 in the chamber 5. Is done. or,
The lower end of the rear end of the cylinder block 13 contacts the hammer 35, and the hammer 35 is rotated in the direction A about the shaft 36. Further, the hammer shear locking portion 16 of the cylinder block 13 moves in the direction A from the pressing portion 43 of the hammer shear 40, and the claw portion 42 of the hammer shear 40 locks with the shear locking portion 38 of the hammer 35. Has moved to the position. 5 to 7, the hammer 35 is rotated in the direction A, and the shear locking portion 38 is locked with the claw portion 42 of the hammer shear 40. Accordingly, the hammer 35 is maintained in a state of being rotated in the direction A against the urging force of the hammer spring 37. On the other hand, in the bolt shear 50, the bolt 9 is moving from above, and the bolt locking portion 52 is rotated upward from the lower end of the bolt 9 by the urging force.

When the bolt 9 finishes moving in the direction A and the user releases his / her hand from the bolt 9, the state shown in FIGS. 8 to 10 is reached, and the bolt 9 is returned to the original position by the urging force of the bolt spring 11. Attempts to return and moves to the muzzle B side, but the bolt locking portion 52 of the bolt shear 50 locks with the bolt shear locking portion 91 provided at the lower end of the bolt 9 on the muzzle side, so that movement to the muzzle side is prevented. You. Next, the user pulls the trigger 46 of the trigger section 44 in the A direction to fire a bullet. Then, as shown in FIGS. 11 to 13, the trigger 46 rotates around the rotation shaft 45 and the arm 47 also rotates.
Trigger shear 48 fixed to the tip of arm 47 also has arm 4
The push portion 49 moves with the rotation of 7, and the push portion 49 presses the intermediate portion of the abutting bolt shear 50 downward. The pressed bolt shear 50 rotates downward around the rotation shaft 51,
The bolt locking portion 52 at the tip is moved downward from the lower end of the bolt 9, and the bolt 9 that has been locked with the bolt locking portion 52 is released from the locked state. Move to. Then, the cylinder block 13 and the nozzle block 17 are also moved in the direction of the muzzle B, and only the first bullet W is moved to the muzzle B of the nozzle block 17.
It is pushed to the side end, moves to the end in the direction A of the barrel 6 as shown in FIGS. 14 to 16, and is loaded and held in the loading packing 8. At this time, the valve 21 is urged by the valve spring 22 in the second air chamber 19 to close the cylinder block side vent hole 18a and open the bullet port side vent hole 18b. Does not depend on the position of the bullet W in the loading packing 8.

On the other hand, in the trigger shear 41, as shown in FIGS.
Then, the hammer shear locking portion 16 presses the pressing portion 43 of the hammer shear 40 downward. The hammer shear 40, which has pressed the pressing portion 43 downward, rotates downward about the rotation shaft 41, the claw portion 42 comes off from the shear locking portion 38, and the claw portion 42 provided at the rotating end portion The lock of the hammer 35 with the shear locking portion 38 is released. Since the lock of the shear locking portion 38 is released, the hammer 35 is rotated in the direction of the muzzle B by the urging force of the hammer spring 37, and FIG.
In the state shown in FIGS. 7 to 18, the valve rod 32 of the hammer valve 30 is pressed. Since the hammer valve 30 is pressed, the hammer valve 30 is opened, and the compressed gas supplied from the gas storage unit 25 and filled in the first air chamber 28 flows in from the inflow port 33 and outflows through the outflow port 34. At this time, if the compressed gas is not filled in the gas storage portion 25 and the first air chamber 28, the hammer valve 30, which has been opened by being pressed by the hammer 35, immediately shifts to the closed state by the urging force. Therefore, the hammer valve 30 is in the closed state even when the compressed gas is replenished by noticing that there is no compressed gas.

The compressed gas that has flowed out of the outlet 34 flows into the second air chamber 19 through the suction / exhaust port 20 of the nozzle block 17, flows into the chamber 5 through the opening 18b in the open state, and further into the chamber 5. The bullet W loaded in the loading packing 8 is pressed. Then, as shown in FIG. 19, the bullet W moves toward the muzzle B and is fired. At the same time that the bullet W is fired, the compressed gas in the shot hole side vent 18b also flows out of the muzzle, and the pressure in the chamber 5, inside the shot hole side vent 18b, and near the shot hole side vent 18b in the second chamber. Instantaneously, a negative pressure is generated, the valve 21 moves in the direction of the muzzle B against the urging force of the valve spring 22, and the intermediate portion 23 closes the bullet hole side vent hole 18b. Then, the compressed gas does not flow in the direction of the muzzle B, but presses the rear end wall of the cylinder block 13 through the cylinder block side ventilation hole 18a, moves the cylinder block 13 in the direction A, and moves the nozzle block 17 and the rear of the cylinder block 13. 20 to 22 between the end walls.
, The compressed gas is filled, and the distance between the nozzle block 17 and the rear end wall of the cylinder block 13 increases. When the distance between the nozzle block 17 and the rear end wall of the cylinder block 13 is slightly opened, the stopper guide groove 14 of the cylinder block 13 is located above the valve stopper 39, the stopper valve 39 moves to the information, and the valve rod 32
Keeps the valve body 31 open by the valve stopper 39. At least until the hammer valve 30 is kept open by the nozzle stopper 39, the hammer valve 30 is kept open by the force of the compressed gas passing through the hammer valve 30. Further, the distance between the nozzle block 17 and the rear end wall of the cylinder block 13 is widened, and eventually, the rear end of the cylinder block 13 pushes the hammer 35 and rotates in the direction A. The valve stopper 39 that has entered the stopper guide groove 14 is pushed back to the stopper contact portion 15. The bolt 9 has a locking projection 12 with the nozzle block 1
I'm trying to contact 7

FIG. 25 is a state diagram showing further movement.
The valve stopper 39 is pushed back by the stopper contact portion 15, the valve rod 32 moves to the initial position, and the valve body 31 is in a closed state. Then, the supply of the compressed gas to the second air chamber 19 ends. Immediately after that, the locking projection 12 of the bolt 9 abuts on the nozzle block 17, and the sliding of the nozzle block 17 in the cylinder block 13 is completed. Further, the hammer 35 is further rotated in the direction A, and is about to lock with the hammer shear 40. The movement of the bolt 9 in the direction A continues further due to the inertial force, resulting in the state shown in FIG. In this state, bolt 9
Is the state most moved in the direction A, and the movement of the bolt 9 in the direction A is stopped by the repulsive force of the bolt spring 11 and terminated. Even if the bolt 9 finishes moving and the cylinder block 13 also finishes moving, the nozzle block 17 slidable in the cylinder block 13 continues to move further in the direction A, and the cylinder block 13 and the nozzle block 17 And the gas in the second air chamber 19 is exhausted to the outside through the intake / exhaust port 20 and the cylinder block 13
To the rear end wall. Further, the hammer 35 is locked with the hammer shear 40.

Subsequently, the bolt 9 returns to the original position by the urging force of the bolt spring 11 from the state shown in FIG. Then, the bolt 9 moves in the direction of the muzzle B again, and FIG.
The subsequent operation described above is repeated. However, since the user keeps pulling the trigger 45 so that the bullets are fired continuously, the push portion 49 of the trigger shear 48 keeps the bolt shear in a downwardly rotating state, and the bolt shear 50 is Since the movement of the bolt 9 in the direction of the muzzle B is not prevented, the bolt 9 moves in the direction of the muzzle B without any hesitation, and the second bullet is loaded into the loading packing 8 at the end of the barrel 6 by the nozzle block 17 that moves together. By repeating the operation described above, the next bullet is fired sequentially. Then, the user sets the trigger 45
When the pulling is stopped, the push portion 49 of the trigger shear 48 releases the downward rotation of the bolt shear 50, the bolt shear 50 rotates upward by the urging force, and the bolt locking portion 52 locks the bolt 9. Since it moves upward from the lower end, the bolt locking part 52 of the bolt shear 50 is locked to the bolt shear locking part 91 of the bolt 9, and the bolt 9 is bolted to the bolt shear 5
The movement in the direction of the muzzle B is stopped by 0. Then, the hammer 35 also keeps rotating in the direction A by the hammer shear 40, and the valve rod 32 of the hammer valve 30.
Is not pressed, the valve body 31 closes the outflow port 34 to prevent the compressed gas from flowing from the first air chamber 28 to the second air chamber 19, and the compressed gas is not supplied to the nozzle block 17. Launch is aborted.

[0036]

Therefore, according to the present invention, the valve is urged by the valve spring in the second air chamber, thereby closing the cylinder block side vent and opening the munition port vent. Accordingly, the position of the bullet is determined independently of the bullet or the packing without holding the valve spring, so that the holding force for the loading packing to hold the bullet can be reduced. Further, even if the setting position of the bullet W shifts due to a decrease in the holding force of the loaded packing due to long-term use or the like, the operation timing of the valve does not shift, and stable use over a long period of time becomes possible. Furthermore, by reducing the holding force of the loaded packing, deterioration of the loaded packing can be reduced, and not only can the stable use for a long period of time be possible, but also by maintaining the state in which the trigger is pulled, the nozzle block can be maintained. Since the movement to the muzzle is not hindered, the next bullet can be sequentially loaded and the next bullet can be fired, so that continuous firing in which bullets are fired continuously can be performed.
Also, because the bullet is loaded after the trigger is pulled,
It can be ended without removing the last loaded bullet.

Further, since the cylinder block is moved to the muzzle side, the hammer valve is opened, and when the cylinder block is slightly moved in the direction A, the valve stopper holds the open state of the hammer valve. If the trigger is accidentally pulled while the compressed gas storage unit and the first air chamber are not full, the bolt moves toward the muzzle and a bullet is loaded, the hammer valve that has been opened will still have its urging force again. The hammer valve, which has been opened, is closed again because the stopper guide groove is located closer to the muzzle side than the valve stopper, and the biasing force is closed again.
Even if the compressed gas is replenished in this state, a bullet is not fired by mistake.
