Hereinafter, the cartridge 100 of this embodiment will be described with reference to the illustrated embodiments. The cartridge 100 of this embodiment is used to hold a BB bullet as a bullet B, and as described later, the held bullet B is moved in the direction of the front F, whereby the bullet B is arranged in the bullet arrangement part 184 described later.

The cartridge 100 of this embodiment has a cylindrical cartridge main body 110 and a bullet having a cylindrical structure in which an inner diameter portion 127 described later becomes a flow path of compressed air and is disposed inside the cartridge main body 110. Lining 120. Hereinafter, when viewing the cartridge 100 from the side, the direction from the rear end 111 of the cartridge main body 110 described later to the front end 185 of the bullet part 170 is referred to as the front F direction. Similarly, in the cartridge 100, the direction from the front end 185 of the bullet part 170 described later to the cartridge body 110 and the rear end 111 is referred to as the rear R direction. Also, when the air gun 500 is viewed from the side with the cartridge 100 loaded in the air gun 500, the direction from the piston cylinder device 550 to the muzzle 530 is referred to as the front F direction. Also, similarly, the direction from the muzzle 530 to the piston cylinder device 550 is referred to as the rear R direction.

The bullet liner 120 is arranged to be freely movable back and forth inside the cartridge body 110 . Further, a bullet spring 130 as a coil spring is arranged between the cartridge main body 110 and the bullet liner 120 . As will be described later, the bullet spring 130 stores the bullet liner 120 in the rear R direction with respect to the cartridge main body 110 .

The cartridge body portion 110 has a rear end portion 111 which is open. Also, inside the cartridge main body 110 and at a position slightly forward in the F direction from the approximate midpoint of the entire length, a main body protrusion 112 protruding into the interior in a rib shape is arranged in a circumferential manner.

The bullet liner 120 has a substantially hollow cylindrical shape, and has a flange-shaped large-diameter portion 121, a central shaft portion 122 with a diameter smaller than the large-diameter portion 121, and a central shaft portion 122 with a smaller diameter than the central shaft portion 122 from the rear R direction toward the front F direction. The thin shaft portion 123 is formed integrally. The large-diameter portion 121 is disposed inside the rear end portion 111 of the cartridge body portion 110 and has a diameter slightly smaller than the inner diameter of the rear end portion 111 . The bullet liner 120 in the cartridge 100 is provided with the center shaft portion 122 inside the bullet spring 130 , and the large diameter portion 121 is in contact with one end of the bullet spring 130 and contacts the bullet spring 130 at the main body protrusion 112 of the cartridge main body 110 . configured in the manner of the other end.

The thin shaft portion 123 has a ring-shaped protruding portion 124 protruding outward in a rib shape, and a groove-shaped groove portion 125 is formed between the central shaft portion 122 and the protruding portion 124 . Also, the bullet liner 120 has a substantially hollow cylindrical inner diameter portion 127 as the hollow portion. The inner diameter portions 127 have the same diameter. As mentioned above, the said inner diameter part 127 is what becomes the flow path of compressed air. Moreover, the thin shaft part 123 has the front-end|tip part 123a at a front-end|tip. The front end portion 123a presses the bullet B as will be described later.

The cylinder-shaped bullet lock 150 is installed on the bullet liner 120, and is arranged at the rear end 151 of the bullet lock 150. The rib-shaped first protrusion 152 protruding inwardly and to the surrounding shape is aligned with the bullet liner 120. The groove portion 125 is arranged so as to be engaged. Furthermore, the bullet lock 150 has two second protrusions 156 protruding inward at the front end 155. The second protrusions 156 at the two positions are arranged with a deviation of 180 degrees inside the cylinder-shaped bullet lock 150 . Therefore, the second protrusions 156 , 156 are disposed so as to face each other and protrude inside the bullet lock 150 .

Furthermore, in FIG. 2, the cylindrical bullet lock 150 is divided into semi-cylindrical bullet lock pieces 150a, 150b and shown in the figure. The bullet locking pieces 150a, 150b respectively have a first protruding portion 152 and a second protruding portion 156 . By assembling the semi-cylindrical bullet lock pieces 150a, 150b, the bullet lock 150 is formed.

A bullet spring 160 as a coil spring is arranged so as to be in contact with the front end portion 155 of the bullet lock 150 . The bullet spring 160 is further in contact with a step portion 181 which will be described later.

Also, the cartridge 100 has a bullet portion 170 inside the front end thereof. The bullet part 170 has a hollow cylindrical small-diameter part 175 and a hollow cylindrical large-diameter part 180 . The small-diameter portion 175 and the large-diameter portion 180 have the same inner diameter, but different outer diameters. Literally, the outer diameter of the small-diameter portion 175 of the bullet is smaller than the outer diameter of the large-diameter portion 180 of the bullet.

In addition, the outside of the large-diameter portion 180 of the bullet portion 170 has a tapered slope portion 181a. Regarding this, as will be described later, airtightness can be ensured when it is in close contact with the chamber gasket 501 a disposed at the rear end of the barrel passage 501 . The chamber gasket 501a is connected with the barrel passage 501, and becomes a cylindrical passage through which bullets and the barrel passage 501 pass together.

The small-diameter part 175 of the bullet is integrated with the large-diameter part 180 of the bullet, and there is a stepped part 181 outside and at the boundary thereof. Also, inside the bullet large-diameter portion 180, there is a bullet holding portion 183 where the bullet B is placed.

In addition, the bullet holder 183 is configured such that a flexible rubber material is attached to the inner peripheral surface so as to accommodate the bullet B. As shown in FIG. In addition, in the front F direction of the bullet holding portion 183, there is a bullet arrangement portion 184 where the bullet B is arranged. Moreover, the large-diameter part 180 has the front end part 185 opened at this front-end|tip. Inside the front end portion 185, a bullet arrangement portion 184 for arranging the bullets B described above is arranged.

In addition, long hole portions 177 , 177 that are elongated in the front-rear direction are arranged in the small-diameter bullet portion 175 . There are two places in the small-diameter portion 175 of the bullet. The elongated holes 177 and 177 provided at two locations are arranged in a circular shape with a deviation of 180 degrees in the cylindrical bullet thin-diameter portion 175 . Therefore, the elongated hole portions 177 , 177 are arranged to face each other in the small-diameter bullet portion 175 . In the elongated hole portions 177, 177, the second protrusion portions 156, 156 are arranged so as to be slidable in the front-rear direction. Therefore, the bullet part 170 can move forward from the molecular bullet lock 150 with respect to the distance in the longitudinal direction of the elongated hole parts 177 , 177 .

In addition, the cartridge 100 has the bullet spring 160 as a coil spring as described above, and the bullet spring 160 is arranged such that one end contacts the front end portion 155 of the bullet lock 150 and the other end contacts the step portion 181 of the bullet 170 .

A user (not shown) inserts the bullet B into the cartridge 100 having the above configuration through the opening of the front end portion 185 , and the bullet B can be placed in the bullet holding portion 183 . However, the position for insertion and placement differs depending on the user, and the bullet B is actually placed at any position from the bullet holding portion 183 to the bullet placement portion 184 .

Furthermore, (A) of FIG. 4 and (B) of FIG. 4 are those who illustrate the appearance of the cartridge 100 in a fully cocked state. The difference between (A) of FIG. 4 and (B) of FIG. 4 is that Is bullet B shown. In the cartridge 100 having the above structure, when the bullet liner 120 arranged inside the cartridge main body 110 is pressed in the forward direction F against the elastic force of the bullet spring 130, the bullet liner 120 moves in the forward F direction. At this time, the front end portion 123 a of the thin shaft portion 123 of the bullet liner 120 pushes out the bullet B placed on the bullet holding portion 183 to move the bullet B to the bullet arrangement portion 184 .

Also, the bullet lock 150 mounted on the bullet liner 120 moves in the direction F forward, compressing the bullet spring 160 .

The bullet portion 170 in contact with the bullet spring 160 moves in the forward F direction by the elastic force of the compressed bullet spring 160 .

The bullet B extruded forward is arranged in the bullet arrangement part 184 inside the bullet part 170 moving in the forward F direction through the front end part 123a of the thin shaft part 123 in the bullet liner 120 . If it is this position, the cartridge 100 with the bullet B is placed in the magazine 502 described later and is fully cocked, so that the bullet B is located in the bullet arrangement part 184, thereby ensuring the same position as the air gun. The distance between the jumps 503 in 500, so that if a bullet B is fired, an appropriate rotation is applied to said bullet B without degrading the hit accuracy.

Hereinafter, an air gun 500 that can use the aforementioned cartridge 100 will be described with reference to the illustrated embodiment. Airsoft 500 is better for so-called quick transitions. The barrel channel 501 is the channel through which the bullet B passes, and the magazine 502 can be filled with the above-mentioned plurality of cartridges 100 (for example, refer to FIG. 9 ). In addition, a jumping portion 503 protruding into the barrel passage 501 is formed in the rear R direction of the barrel passage 501 . The jumping part 503 is used to impart a predetermined rotation to the high-speed moving bullet B to improve the hitting accuracy.

Also, the cartridge 100 is used to fill the bullet B, and the bullet B is kept in a fixed position until the bullet is fired when the cartridge 100 is filled in the magazine 502, and the bullet B is fired from the muzzle 530 by the compressed air ejected from the nozzle 50. .

A nozzle 50 is arranged in the rear direction R 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 air gun 500 , and the piston 570 is slidably arranged with respect to the air cylinder 560 by the expansion and contraction force of the spring 580 described above. In addition, the nozzle 50 further has a nozzle gasket 51 in order to be in close contact with the cartridge 100 arranged in the magazine 502 .

Furthermore, the air gun 500 has a pressing device 10 for pressing the nozzle 50 against 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 100 arranged 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 100 arranged in the magazine 502 by the pressing device 10, thereby enabling the nozzle 50 to be in close contact with the cartridge 100 arranged in the magazine 502 as described above. It leaks compressed air. In addition, since the nozzle 50 is pressed against the cartridge 100 disposed in the magazine 502 by putting the hammer 20 in a fully cocked state, 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 100 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. 12 , 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. 9 and Fig. 10 are showing the state of half cocking, and Fig. 11 and Fig. 12 are showing the state of full cocking. Moreover, the states of the cartridge 100 in FIGS. 9 and 10 are also shown in FIG. 3(A) and FIG. 3(B). Moreover, the states of the cartridge 100 in FIGS. 11 and 12 are also shown in FIG. 4(A) and FIG. 4(B).

A user (not shown) accommodates the bullet B in the bullet holding portion 183 of the cartridge 100 . At this time, there is no particular problem as long as the user (not shown) inserts the bullet B to the position from the bullet holding portion 183 to the bullet arrangement portion 184 . That is, this is because the bullet B accommodated at any position from the bullet holding portion 183 to the bullet arrangement portion 184 is extruded from the bullet liner 120 and moved to the The configuration part 184 is configured.

In this way, when the bullet B is fully cocked and the bullet B can be fired, the bullet B is moved from the bullet holding portion 183 to be arranged in the bullet arrangement portion 184, so the position where the bullet B is arranged and the position of the jumping portion 503 are always constant. . Even if the user inserts the bullet B and there is a positional deviation, the hit accuracy does not deteriorate. This is because the bullet B is extruded from the bullet liner 120 and moved to the bullet placement portion 184 (see FIG. 4(A), FIG. 4(B), FIG. 11 , FIG. 12 ).

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 100 arranged 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 100 arranged in the magazine 502 . This is sometimes called a half-standby.

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 that the nozzle 50 presses against the cartridge 100 disposed in the magazine 502 , and the nozzle 50 presses the bullet liner 120 disposed in the cartridge 100 disposed in the magazine 502 . At this time, the nozzle 50 only presses the bullet liner 120 in the cartridge 100 disposed in the magazine 502, so the magazine 502 itself is not pressed. Thus, the magazine 502 does not move in the forward F direction, as in previous air guns.

In this way, when the nozzle cam 40 presses the nozzle 50 , the coupling rod 80 connected to the hammer 20 further presses down the piston 570 to store pressure on the 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 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 . In addition, as described above, the nozzle 50 presses the cartridge liner 120 disposed in the cartridge 100 within the magazine 502 .

As described above, the bullet B arranged in the bullet holding portion 183 in the large diameter portion 180 is extruded from the bullet liner 120 and moved to the bullet arrangement portion 184 . In this way, if the bullet B is fully cocked and the bullet B is fired, the bullet B is placed in the bullet holding portion 184, so the position where the bullet B is placed and the jumping portion 503 are always constant, and the hit accuracy will not be reduced.

Also, in the fully cocked state, the bullet liner 120 moves in the forward F direction by compressing the bullet spring 130 . Thereby, when the bullet lock 150 engaged with the groove portion 125 moves in the forward F direction, the bullet spring 160 is charged. The bullet portion 170 is moved forward F by the accumulated pressure, and the tapered inclined portion 181a is in close contact with the chamber gasket 501a disposed at the rear end of the barrel passage 501 to ensure airtightness. Therefore, the risk of leaking compressed air from between the sloped portion 181a and the barrel passage 501 is reduced.

Also, even if the nozzle cam 40 presses the nozzle 50, the nozzle 50 also presses the bullet liner 120 disposed in the cartridge 100 inside the magazine 502, so the magazine 502 itself does not move in the forward F direction, unlike the previous Unlike an air gun, the air gun 500 of this embodiment can obtain an operational feeling similar to that of a real gun.

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 injected into the cartridge 100 arranged in the magazine 502, and the injection passes through the inner diameter portion 127 and the bullet arrangement portion 184, and the bullet B is fired. .

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 in the hammer 20, so no extra force will be applied other than that, and it is also possible to achieve the same effect as the real one. The action of pulling the trigger 700 of the gun. In this way, the risk of further reduction in hit accuracy can be reduced as much as possible without deviating from the once-determined target.
