Description

Pressing device for pressing nozzle and air gun having said pressing device

The present invention relates to a pressing device for pressing a nozzle for ejecting compressed air on a magazine, and an air gun with the pressing device.

With so-called airsoft guns, the hammer is fired and the trigger is pulled, whereby compressed air is ejected from the nozzle into the magazine. By this ejection, there is one who fires the bullet held in the cartridge arranged in its magazine.

Such an air gun, for example, is disclosed in Japanese Utility Model Registration No. 3175969, which discloses "a fixed load reducing device, which is characterized in that, by pulling the hammer, it is locked to the stopper and at the same time, the hammer is linked with the hammer. The spring of the piston cylinder device accumulates pressure, pulls the trigger to release the lock of the stopper, releases the pressure accumulation of the above spring, thereby generating compressed air through the piston cylinder device, and firing bullets through the above compressed air In the gun, in order to reduce the load when the hammer is raised and the cocking operation is started, a non-linear spring is used as a spring acting on the action member of the piston cylinder device."

However, in the above-mentioned device, by pulling the trigger, the nozzle is pressed against the magazine, and compressed air is ejected from the nozzle into the magazine, but if the trigger is not pulled hard, the pressing force against the nozzle of the magazine is weakened, Sometimes compressed air leaks from this part. Therefore, it is recommended to pull the trigger firmly to maintain the pressure of the nozzle against the magazine.

In addition, if the trigger is pulled strongly as described above, the target will be deviated and the hit accuracy will be reduced. Also, in the real gun, in order not to reduce the hit accuracy, the trigger is not pulled hard, so the action of pulling the trigger requires different processing in the real gun and the air gun that simulates the real gun.

The present invention is constituted and functions as described above, and therefore, it is possible to provide a pressing device for pressing a nozzle capable of improving causes of decrease in hit accuracy and preventing leakage of compressed air, and an air gun having the pressing device.

Hereinafter, the pressing device 10 of this embodiment and the air gun 500 of this embodiment having the pressing device 10 will be described with reference to the illustrated embodiment. Airsoft 500 is better for so-called quick transitions. The gun barrel 501 is the channel through which the bullet B passes, and the magazine 502 can be filled with a plurality of cartridges 520 (referring to FIG. 7 ) which will be described later. In addition, in the following, the direction from the piston cylinder device 550 to the muzzle 530 is referred to as the front F direction in the state viewed from the side in the air gun 500 . Also, similarly, let the direction from the muzzle 530 to the piston cylinder device 550 be the rearward R direction. Furthermore, bullet B is preferably a BB bullet.

Also, the cartridge 520 is used to fill the bullet B. The bullet B is kept in a fixed position with the cartridge 520 loaded in the magazine 502 until fired, and the bullet B is fired from the muzzle 530 by the compressed air ejected from the nozzle 50 .

A nozzle 50 is disposed on the rear R side of the magazine 502, and the nozzle 50 is connected to a piston cylinder device 550 through a pipe portion 60 composed of a pipe described later. The piston-cylinder unit 550 is composed of a cylinder 560 and a piston 570 arranged under the grip portion of the gun body. In addition, the piston cylinder device 550 has a spring 580 of the pressure accumulation piston 570 , and the spring 580 is arranged inside the piston 570 .

In the above-described embodiment, the air cylinder 560 is fixed to the gun body side, and the piston 570 is arranged to be slidable with respect to the air cylinder 560 by the expansion and contraction force of the spring 580 described above. In addition, the nozzle 50 also has a nozzle gasket 51 so as to be in close contact with the cartridge 520 arranged in the magazine 502 .

In addition, the air gun 500 has a pressing device 10 that presses the nozzle 50 and the cartridge 520 disposed in the magazine 502 by the full cocking action of the hammer 20 . By having the pressing device 10, the nozzle 50 is brought into close contact with the cartridge 520 disposed in the magazine 502, thereby preventing leakage of compressed air.

Furthermore, it can be said that the air gun 500 has an inner liner frame 650 constituting an inner frame, and the pressing device 10 is disposed on the inner liner frame 650 .

The pressing device 10 has a hammer part 30 that engages with the hammer 20 and a nozzle cam 40 that rotates by engaging with the hammer part 30 . The hammer 20 is used for semi-standby or full-standby operations as described later, and has a finger hook 21 where the user (not shown) puts his or her finger on the hammer 20 and a hook that engages with the hammer part 30 22 , the hammer 20 is rotatably supported by the rotating shaft 25 relative to the air gun 500 , and installed.

When the hammer 20 is in a fully cocked state, the hammer part 30 rotates by engaging with the hammer 20 , and the nozzle cam 40 rotates by engaging with the hammer part 30 , As a result, the nozzle cam 40 presses the nozzle 50 . In this way, the nozzle 50 is pressed against the cartridge 520 arranged in the magazine 502 by the pressing device 10, thereby enabling the nozzle 50 to be in close contact with the cartridge 520 arranged in the magazine 502 as described above. It leaks compressed air. Moreover, the nozzle 50 is pressed against the cartridge 520 disposed in the magazine 502 by the hammer 20 in the fully cocked state, so the tightness will not be affected by pulling the trigger 700 . Therefore, the action of pulling the trigger 700 can be performed almost the same as a real gun.

Moreover, the hammer 20 has a coupling rod connection portion 23 , literally, the coupling rod connection portion 23 is connected to a coupling rod 80 , and the coupling rod 80 is connected to a piston cylinder device 550 . Specifically, the coupling rod 80 is connected to the piston connecting portion 571 that is a part of the piston 570 , and when the hammer 20 is pulled, the piston 570 is pushed down through the coupling rod 80 to store pressure in the spring 580 .

Further, the hammer 20 has a hammer rotating portion 24 that is circular in plan view, and the engaging portion 22 is arranged so as to protrude from the rotating portion 24 . In addition, both the finger hook portion 21 and the engaging portion 22 are arranged so as to protrude from the rotating portion 24 . Therefore, in the state of not being cocked, the hammer part engaging receiving part 32 described later is disposed near the one end engaging part 21a, and before fully cocking, the hammer part engaging receiving part 32 and the engaging part 22 snaps. Further, at the center of the hammer rotating portion 24, there is a rotating shaft portion 25, which is rotatably pivotally supported when the hammer 20 is cocked.

Moreover, the hammer 20 has a trigger first engaging portion 28 engaged with the trigger 700 , and the trigger first engaging portion 28 is roughly in a stepped shape in which the circular hammer rotating portion 24 is missing in plan view. Also, the hammer 20 has a trigger second engaging portion 29 that engages with the trigger 700 , and the trigger second engaging portion 29 has a substantially stepped shape in which a part of the hammer rotating portion 24 that is circular in plan view is missing. Both the first trigger engaging portion 28 and the second trigger engaging portion 29 are provided as part of the hammer rotating portion 24 .

The hammer part 30 has a circular hammer part rotating part 31 and a hammer part engagement receiving part 32 protruding from the hammer part rotating part 31. The central portion is coaxially and rotatably supported by the rotating shaft portion 25 .

The hammer part engagement receiving part 32 is literally engaged with the above-mentioned engaging part 22. When the hammer 20 is operated to be struck, the engaging part 22 rotates while the hammer rotating part 24 rotates. And the engaging part 22 is engaged with the hammer part engaging receiving part 32 , whereby the hammer part engaging receiving part 32 also rotates.

In addition, the nozzle cam 40 has a rotating part 43 between the one end part 41 and the other end part 42. The rotating part 43 is rotatably supported on the shaft part 600 attached to the air gun 500, and the one end part 41 and the other end part 42 are like a seesaw. Shaft support for free swing. In addition, the one end portion 41 is engaged with the hammer part engaging receiving portion 32 , whereby the other end portion 42 is pressed in the direction of the muzzle 530 (the front F direction).

Also, one end portion 41 of the nozzle cam 40 is biased by the nozzle cam spring 45 so as to rotate in the rear R direction. Thereby, the other end portion 42 connected to the nozzle 50 is charged so that the nozzle 50 is separated from the cartridge 520 arranged in the magazine portion 502 .

One end portion 41 of the nozzle cam 40 is arranged so as to be engaged with an end engaging portion 21 a arranged in the immediate vicinity of the finger hook portion 21 of the hammer 20 . In this way, the one end engaging portion 21 a is engaged with the one end portion 41 of the nozzle cam 40 , and the nozzle cam 40 is slightly pressed in the forward F direction against the pressing force of the nozzle cam spring 45 .

Also, as described above, the nozzle 50 is connected to the hollow pipe portion 60 . The pipe portion 60 is used to connect with the air cylinder 560 and send the compressed air generated by the piston cylinder device 550 to the nozzle 50 . The tube portion 60 is preferably made of flexible synthetic resin.

In addition, even if the tube portion 60 is made of a flexible synthetic resin, the tube portion 60 may have a certain degree of rigidity in order to prevent extrusion. Therefore, there is a tube pressing portion 70 that presses the tube portion 60 for so-called bending. The tube pressing part 70 has the tube roller part 71 which contacts the tube part 60, and the tube spring 72 which presses the said tube roller part 71 from the rear R direction to the front F direction. The tube spring 72 is preferably a so-called torsion spring. Therefore, since the tube pressing part 70 pushes the tube part 60 to the front F direction, it is arrange|positioned in the rear R direction of the tube part 60. As shown in FIG. Also, in this embodiment, it is preferable that the position where the tube pressing part 70 presses the tube part 60 is arranged at an intermediate point between the cylinder device 550 and the nozzle 50 . This is because, in this position, when a pressing force that causes bending of the pipe portion 60 is applied, the force becomes relatively small.

From FIG. 5 to FIG. 10 , a state in which the hammer 20 is pulled by the user (not shown) will be described. Here, Fig. 5 and Fig. 6 are diagrams showing the state before pulling the hammer, Fig. 7 and Fig. 8 are showing the state of half cocking, and Fig. 9 and Fig. 10 are showing the state of full cocking. A user (not shown) starts to pull the hammer 20 in the air gun 500 having the above-mentioned structure. Before the unillustrated user pulls the hammer 20, the nozzle 50 is pressed against the cartridge 520 disposed in the magazine 502 by the pressing device 10, but if the unillustrated user starts to pull the hammer 20, one end is stuck. The engagement between the engaging portion 21a and the one end portion 41 is released, the nozzle cam 40 rotates in the rear R direction, and the other end portion 42 of the nozzle cam 40 rotates, and later moves in the rear R direction, whereby the other end portion 42 The connected nozzle 50 moves in the rear direction R, and a gap is created between the nozzle 50 and the cartridge 520 arranged in the magazine 502 . This is sometimes called a half-standby. In this case, the rotation of the magazine 502 in the air gun 500 of this embodiment is fixed. However, it is not limited thereto, and there may be specifications that allow the rotation of the magazine 502 .

Also, the user (not shown) starts to pull the hammer 20 in the air gun 500 having the above-mentioned structure to perform half-standby. As a result, the nozzle 50 starts to move slightly in the rear direction R, and further bends the pipe portion 60 connected to the nozzle 50 , and the pipe pressing portion 70 presses the pipe portion 60 .

As described above, when the nozzle 50 starts to move in the rear R direction by half-arming, the pipe portion 60 may hinder the movement due to its elasticity. In this case, the tube roller part 71 in the tube pressing part 70 is pressed from the rear R direction to the front F direction by the tube spring 72, so that the tube part 60 is held against the elastic force of the tube part 60. The bending from the rear R direction to the front F direction works, and resists this elastic force. Thereby, even if there is the tube portion 60 that does not exist in the actual gun, the elastic force against the force that tries to bend the tube portion acts in such a manner that the tube pressing portion 70 cancels it.

In order to maintain the semi-cocked state, the trigger 700 is engaged with the first trigger engaging portion 28 of the hammer 20 . At this time, the coupling rod 80 connected to the hammer 20 depresses the piston 570 and accumulates the spring 580 .

Next, the user (not shown) further pulls the hammer 20 . With this, the engaging portion 22 rotates in the rear R direction while the hammer rotating portion 24 rotates, and the engaging portion 22 engages with the hammer component engaging receiving portion 32 , whereby the hammer component engages. The joint receiving portion 32 also rotates in the rear R direction.

By the rotation of the hammer part engaging receiving part 32, the hammer part engaging receiving part 32 is engaged with the one end 41 of the nozzle cam 40, whereby the one end 41 surrounds the shaft part 600 installed on the air gun 500 By rotating, the other end portion 42 moves in the forward F direction. The other end 42 is connected to the nozzle 50 , so the nozzle 50 is pressed against the cartridge 520 arranged in the magazine 502 , and the nozzle 50 is in close contact with the cartridge 520 arranged in the magazine 502 . In this way, the nozzle cam 40 presses the nozzle 50 . At this time, the coupling rod 80 connected with the hammer 20 further depresses the piston 570 and accumulates the pressure spring 580 . In this case, as long as the piston 570 is fully charged by the compressed spring 580, it will be in a full bottom state. This state is sometimes referred to as fully armed.

In the fully cocked state, the rotation of the magazine 502 in the air gun 500 of this embodiment is fixed. In addition, in order to maintain the full cocking state, the trigger 700 is disengaged from the first trigger engaging portion 28 of the hammer 20 and engaged with the second trigger engaging portion 29 .

Next, when a user (not shown) pulls the trigger 700 in the fully cocked state, the engagement between the trigger 700 and the second trigger engaging portion 29 of the hammer 20 is released. At this time, as the compressed spring 580 returns to its natural length, the piston 570 is pushed up, thereby generating compressed air. The generated compressed air is supplied to the nozzle 50 through the pipe portion 60 , and the compressed air is sprayed into the cartridge 520 disposed in the magazine 502 to fire the bullet B.

At this time, the action of pulling the trigger 700 is only to release the engagement between the trigger 700 and the second trigger engaging part 29 of the hammer 20, so no extra force will be applied other than that, and it is possible to achieve The action of pulling the trigger 700 . Thereby, the risk of reduction in hit accuracy can be reduced as much as possible without deviating from the once-determined target.
