Description

The present invention relates to an air gun cartridge used in an air gun capable of firing bullets, and an air gun using the cartridge.

Air guns capable of firing bullets include revolver-type air guns, and this air gun employs a system in which BB bullets are loaded into a so-called cylindrical cartridge. For example, Japanese Unexamined Patent Application Publication No. 2014-222135 discloses an invention relating to a simulated gun cartridge for an air gun that provides a good hop-up effect in order to improve hit accuracy.

The above invention is a imitation gun cartridge for use in a imitation gun capable of firing a bullet, which has a cylindrical structure with a compressed air flow path inside, and has an inlet at the rear end and an outlet at the tip. and a bullet holding section that holds the bullet while loading the bullet into the outflow port side of the tip. The bullet holding section holds the bullet so that it does not come out. and is configured to fire a bullet when compressed air pressure greater than the holding force is applied.

Since this cartridge holds the bullet at the tip of the main body near the hop-up part, it is possible to obtain a sufficient hop-up effect, as well as excellent straightness and high accuracy. and has received high praise from the market.

However, although the BB bullet is held within the cartridge, the user must insert the BB bullet into the cartridge to hold it. In this work, since the position in which the BB bullet is held in the cartridge differs depending on the user, the distance from the pop-up portion for hopping up differs depending on the position, and the accuracy of hitting may vary.

On the other hand, the bullet is fired by pressing the cartridge held in the magazine, and in this case, the magazine holding the cartridge may also move forward. In this way, the movement of the magazine forward results in an operation different from that of a real gun, and the feeling of operation may differ from that of a real gun. Therefore, there is also a demand to make the feeling of operation similar to that of a real gun.

Hereinafter, the cartridge 100 of this example will be described with reference to the illustrated embodiments. The cartridge 100 of this embodiment is for holding a BB bullet which is a bullet B, and by moving the held bullet B in the forward direction F as will be described later, the bullet B is placed in a bullet arrangement portion described later. 184.

The cartridge 100 of this embodiment includes a cartridge main body 110 having a cylindrical shape, and a cart inner having a cylindrical structure disposed inside the cartridge main body 110 and having an inner diameter portion 127, which will be described later, serving as a flow path for compressed air. 120. Hereinafter, when viewing the cartridge 100 from the side, the direction from the rear end portion 111 of the cartridge main body portion 110 to the front end portion 185 of the bullet portion 170 is referred to as the forward F direction. Similarly, in the cartridge 100, the direction from the tip end portion 185 of the bullet portion 170 to be described later to the rear end portion 111 of the cartridge body portion 110 is called the rearward R direction. Further, when the air gun 500 is loaded with the cartridge 100, the direction from the piston cylinder device 550 to the muzzle 530 when viewed from the side of the air gun 500 is referred to as the forward F direction. Similarly, the direction from the muzzle 530 to the piston cylinder device 550 is called the rearward R direction.

The cart inner 120 is arranged to be movable back and forth inside the cartridge main body 110 . A cart spring 130 that is a coil spring is arranged between the cartridge main body 110 and the cart inner 120 . As will be described later, the cart spring 130 urges the cart inner 120 in the rear R direction with respect to the cartridge main body 110 .

The cartridge body 110 has a rear end 111, and the rear end 111 is open. Inside the cartridge main body 110, at a position slightly forward in the F direction from the approximate midpoint of the entire length, there is arranged a main body projection 112 that protrudes inside in a circular rib-like manner.

The cart inner 120 has a substantially hollow cylindrical shape, and has a brim-shaped large-diameter portion 121, a central shaft portion 122 smaller in diameter than the large-diameter portion 121, and a central shaft portion 122 extending from the rear R direction to the front F direction. and a thin shaft portion 123 having a small diameter, which are integrally formed. The large diameter portion 121 is arranged inside the rear end portion 111 of the cartridge main body portion 110 and has a diameter slightly smaller than the inner diameter of the rear end portion 111 . The cart inner 120 of the cartridge 100 has its center shaft portion 122 disposed inside the cart spring 130 , and the large diameter portion 121 is in contact with one end of the cart spring 130 , and the cart spring 130 are arranged so that the other end of the

The thin shaft portion 123 has a protruding portion 124 that protrudes outward in a circumferential rib-like shape, and forms a groove portion 125 between the central shaft portion 122 and the protruding portion 124 . In addition, the cart inner 120 has an inner diameter portion 127 which is a hollow portion of a substantially hollow cylindrical shape. Its inner diameter 127 has a uniform diameter. As described above, this inner diameter portion 127 serves as a flow path for compressed air. Further, the thin shaft portion 123 has a tip portion 123a at its tip. This tip portion 123a presses the bullet B as will be described later.

The bullet lock 150 having a cylindrical shape is attached to the cart inner 120, and is arranged at a rear end portion 151 of the bullet lock 150. A rib-shaped first protrusion 152 protruding inward and circularly It is arranged to engage with the groove 125 of the cart inner 120 . The bullet lock 150 also has two inwardly projecting second projections 156 on its distal end 155 . Two second protrusions 156 are arranged inside the cylindrical bullet lock 150 with a 180 degree shift. Accordingly, the second protrusions 156 , 156 are arranged to protrude from each other inside the bullet lock 150 .

In FIG. 2, the cylindrical bullet lock 150 is shown divided into semi-cylindrical bullet lock pieces 150a and 150b. Each of the bullet lock pieces 150a, 150b has a first protrusion 152 and a second protrusion 156. As shown in FIG. The bullet lock 150 is constructed by assembling the semi-cylindrical bullet lock pieces 150a and 150b.

A bullet spring 160 , which is a coil spring, is arranged so as to be in contact with the tip portion 155 of the bullet lock 150 . The bullet spring 160 is also in contact with a stepped portion 181, which will be described later.

Further, the cartridge 100 has a bullet portion 170 inside its tip. The bullet portion 170 has a hollow tubular small diameter portion 175 and a hollow tubular large diameter portion 180 . The small diameter portion 175 and the large diameter portion 180 have the same inner diameter, but different outer diameters.

Further, the outside of the large diameter portion 180 of the bullet portion 170 has a tapered slope portion 181a. As will be described later, airtightness can be ensured when the chamber packing 501a arranged at the rear end of the barrel passage 501 is brought into close contact. The chamber packing 501a is connected to the barrel passage 501 and forms a cylindrical passage along with the barrel passage 501 through which a bullet passes.

The bullet small-diameter portion 175 and the bullet large-diameter portion 180 are integral with each other, and have a step portion 181 on the boundary between them. Further, a bullet holding portion 183 for holding a bullet B is provided inside the bullet large diameter portion 180 .

Further, the bullet holding portion 183 is configured such that a flexible rubber material is adhered to the inner peripheral surface thereof so as to accommodate the bullet B. As shown in FIG. It also has a bullet placement portion 184 for placing a bullet B in the front F direction of the bullet holding portion 183 . Also, the large diameter portion 180 has a distal end portion 185 that opens at its distal end. Inside the tip portion 185, a bullet placement portion 184 for placing the bullet B described above is arranged.

Further, elongated hole portions 177 , 177 having a hole shape elongated in the front-rear direction are arranged in the bullet small-diameter portion 175 . These are owned by two at the bullet small diameter 175 . The two elongated holes 177, 177 are arranged with a 180-degree shift in the circular bullet small diameter portion 175 having a cylindrical shape. Therefore, the elongated holes 177 , 177 are arranged to face each other at the small diameter portion 175 of the bullet. The above-described second protrusions 156, 156 are arranged in the elongated holes 177, 177 so as to be slidable in the front-rear direction. Therefore, the bullet portion 170 can move forward with respect to the bullet lock 150 by the longitudinal distance of the elongated holes 177 , 177 .

As described above, the cartridge 100 has a bullet spring 160 which is a coil spring. One end of the bullet spring 160 is in contact with the tip 155 of the bullet lock 150 and the other end is in contact with the stepped portion 181 of the bullet 170. are placed.

A user (not shown) can insert a bullet B into the cartridge 100 configured as described above through an opening in the tip portion 185 and place the bullet B in the bullet holding portion 183 . However, the insertion position differs depending on the user.

4A and 4B show the state of the cartridge 100 in a fully cocked state, and the difference between FIGS. 4A and 4B is whether or not the bullet B is shown. In the cartridge 100 configured as described above, when the cart inner 120 disposed inside the cartridge main body 110 is pushed in the forward F direction against the elastic force of the cart spring 130, the cart inner 120 moves forward in the F direction. At that time, the distal end portion 123 a of the thin shaft portion 123 of the cart inner 120 pushes out the bullet B placed in the bullet holding portion 183 and moves the bullet B to the bullet placement portion 184 .

Also, the bullet lock 150 attached to the cart inner 120 moves forward in the F direction, compressing the bullet spring 160 .

The bullet part 170 in contact with the bullet spring 160 moves forward in the F direction due to the elastic force of the compressed bullet spring 160 .

The bullet B pushed forward by the distal end portion 123a of the thin shaft portion 123 of the cart inner 120 is placed in the bullet placement portion 184 inside the bullet portion 170 moved in the forward F direction as described above. At this position, the cartridge 100 having the bullet B is placed in the later-described magazine 502 and fully cocked to position the bullet B in the bullet placement portion 184. Since the distance to the hop-up part 503 can be maintained, when the bullet B is fired, the bullet B is given an appropriate spin, and the accuracy of hitting is not deteriorated.

An air gun 500 that can use the cartridge 100 described above will now be described with reference to the illustrated embodiments. The air gun 500 is preferably of so-called revolver type. The barrel passage 501 serves as a passage for the bullet B to pass through, and the magazine 502 can be loaded with a plurality of cartridges 100 (see FIG. 9, for example). Also, a hop-up portion 503 projecting into the barrel passage 501 is formed in the rear R direction of the barrel passage 501 . The hop-up part 503 gives a predetermined rotation to the bullet B moving at high speed, and is for enhancing the accuracy of hitting.

Further, the cartridge 100 is for loading a bullet B, and the bullet B is held in place until the cartridge 100 is loaded in the magazine 502 until it is fired. fired from.

A nozzle 50 is arranged behind the magazine 502 in the R direction, and the nozzle 50 is connected to a piston cylinder device 550 by a hose portion 60 made of a pipe, which will be described later. The piston-cylinder device 550 consists of a cylinder 560 and a piston 570 located below the grip portion of the gun body. The piston cylinder device 550 also has a spring 580 that accumulates pressure on the piston 570 , and the spring 580 is arranged inside the piston 570 .

In this embodiment, the cylinder 560 is fixed to the air gun 500, and the piston 570 is slidably arranged with respect to the cylinder 560 by the expansion and contraction force of the spring 580 described above. Further, the nozzle 50 further has a nozzle packing 51 for closely contacting the cartridge 100 arranged in the magazine 502 .

The air gun 500 also has a pressing device 10 that presses the nozzle 50 against the magazine 502 by full cocking action of the hammer 20 . By having this pressing device 10, it is possible to prevent compressed air from leaking by bringing the nozzle 50 into close contact with the cartridge 100 arranged in the magazine 502. FIG.

The air gun 500 also has an inner frame 650 that constitutes, so to speak, an endoskeleton, and the pressing device 10 is arranged on the inner 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 for half-cocking or full-cocking operations, as will be described later. The hammer 20 is rotatably supported and attached to the air gun 500 by the rotating shaft portion 25 .

When the hammer 20 is fully cocked, engagement with the hammer 20 rotates the hammer part 30. Engagement with the hammer part 30 rotates the nozzle cam 40, thereby rotating the nozzle cam 40. , to press the nozzle 50 . By pressing the nozzle 50 against the cartridge 100 arranged in the magazine 502 by the pressing device 10 in this manner, the nozzle 50 and the cartridge 100 arranged in the magazine 502 can be brought into close contact as described above. Compressed air can be prevented from leaking. Further, by fully cocking the hammer 20 , the nozzle 50 is pressed against the cartridge 100 arranged in the magazine 502 , so the tightness of contact is not affected by the operation of pulling the trigger 700 . Therefore, the operation of pulling the trigger 700 can be performed in substantially the same manner as a real gun.

The hammer 20 also has a connecting rod connecting portion 23 , literally connecting rod connecting portion 23 is connected to connecting rod 80 , and connecting rod 80 is connected to piston cylinder device 550 . Specifically, the connecting rod 80 is connected to a piston connecting portion 571 that is part of the piston 570 , and when the hammer 20 is pulled, the piston 570 is pushed down through the connecting rod 80 so as to accumulate the spring 580 . .

Further, the hammer 20 has a hammer rotating portion 24 having a circular shape in plan view, and the engaging portion 22 described above is arranged so as to protrude from the rotating portion 24 . Both the finger hooking portion 21 and the engaging portion 22 are arranged so as to protrude from the rotating portion 24 . Therefore, in the non-cocked state, the hammer part engagement receiving portion 32, which will be described later, is arranged near the one end engaging portion 21a, and just before full cocking, the hammer part engagement receiving portion 32 is engaged. engages with portion 22; Further, a rotating shaft portion 25 is provided at the center of the hammer rotating portion 24, and the rotating shaft portion 25 is rotatably supported when the hammer 20 is cocked.

The hammer 20 also has a first trigger engaging portion 28 that engages with the trigger 700, and the first trigger engaging portion 28 has a stepped shape resulting from a loss of the hammer rotating portion 24, which has a substantially circular shape in plan view. ing. Further, the hammer 20 has a second trigger engaging portion 29 that engages with the trigger 700, and the second trigger engaging portion 29 is a step formed by missing a part of the hammer rotating portion 24 having a substantially circular shape in plan view. is presenting. 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. It is coaxially and rotatably supported by the central portion of the portion 24 and the rotating shaft portion 25 .

The hammer part engagement receiving portion 32 literally engages with the above-described engaging portion 22, and when the hammer 20 is cocked, the hammer rotating portion 24 rotates and the engaging portion 22 rotates. Then, when the engagement portion 22 engages with the hammer part engagement receiving portion 32, the hammer part engagement receiving portion 32 also rotates.

The nozzle cam 40 has one end 41, the other end 42, and a rotating portion 43 therebetween. and the other end 42 are pivotally supported to be able to swing like a seesaw. Also, the one end portion 41 is engaged with the hammer parts engagement receiving portion 32 to press the other end portion 42 in the direction of the muzzle 530 (forward direction F).

One end 41 of the nozzle cam 40 is biased by a nozzle cam spring 45 so as to rotate in the rear R direction. This urges the other end 42 , which is connected to the nozzle 50 , away from the cartridge 100 with the nozzle 50 located within the magazine 502 .

One end portion 41 of nozzle cam 40 is arranged to engage with one end engaging portion 21 a arranged near the base of finger hook portion 21 of hammer 20 . By engaging with the one end portion 41 of the nozzle cam 40 in this way, the one end engaging portion 21a presses the nozzle cam 40 slightly forward in the F direction so as to oppose the pressing force of the nozzle cam spring 45 .

Also, as described above, the nozzle 50 is connected to the hollow hose portion 60 . The hose portion 60 is connected to the cylinder 560 and is for delivering the compressed air generated by the piston-cylinder device 550 to the nozzle 50 . The hose portion 60 is preferably made of flexible synthetic resin.

Further, even if the hose portion 60 is made of flexible synthetic resin, it may have a certain degree of rigidity in order to prevent the hose portion 60 from collapsing. For this purpose, it has a hose pressing portion 70 that presses the hose portion 60 so as to so-called buckle. The hose pressing portion 70 has a hose roller portion 71 that contacts the hose portion 60 and a hose spring 72 that presses the hose roller portion 71 from the rear R direction to the front F direction. The hose spring 72 is preferably a so-called torsion spring. Therefore, the hose pressing portion 70 is arranged in the rear R direction of the hose portion 60 because it pushes the hose portion 60 forward in the F direction. Further, the position where the hose pressing portion 70 presses the hose portion 60 is preferably arranged at the intermediate point between the cylinder device 550 and the nozzle 50 in this embodiment. This is because at that position, when a pressing force that triggers bending of the hose portion 60 is applied, the force is relatively small.

5 to 12, a state in which a user (not shown) pulls the hammer 20 will be described.
5 and 6 show the state before the hammer is pulled, FIGS. 9 and 10 show the half-cocked state, and FIGS. 11 and 12 show the fully-cocked state. is shown. The state of the cartridge 100 shown in FIGS. 9 and 10 is also shown in FIGS. 3A and 3B. The state of the cartridge 100 shown in FIGS. 11 and 12 is also shown in FIGS. 4A and 4B.

A user (not shown) holds the bullet B in the bullet holding portion 183 of the cartridge 100 in advance. At this time, if the user (not shown) inserts the bullet B into the position from the bullet holding portion 183 to the bullet placing portion 184, there is no particular problem. That is, when the user (not shown) fully cocks, the bullet B stored in any position from the bullet holding portion 183 to the bullet placement portion 184 is pushed out by the cart inner 120 and moved to the bullet placement portion 184. This is because they are arranged.

In this manner, when the bullet B is fully cocked and ready to be fired, the bullet B moves from the bullet holding section 183 and is placed in the bullet placement section 184. , the position of the pop-up portion 503 is always constant. Even if the user inserts the bullet B and there is a positional deviation, the accuracy of hitting does not deteriorate. This is because the bullet B is pushed out by the cart inner 120 and moves to the bullet placement portion 184 (see FIGS. 4A, 4B, 11 and 12).

A user (not shown) begins to pull the hammer 20 in the air gun 500 having the above configuration. Before the hammer 20 is pulled by the user (not shown), the nozzle 50 is pressed against the cartridge 100 placed in the magazine 502 by the pressing device 10. When the user (not shown) starts pulling the hammer 20, the nozzle 50 is temporarily engaged. The joint portion 21a is disengaged from the one end portion 41, the nozzle cam 40 rotates in the rearward R direction, and the other end portion 42 of the nozzle cam 40 rotates and slightly moves in the rearward R direction. The nozzle 50 connected to 42 moves in the rear R direction, creating a gap between the nozzle 50 and the cartridge 100 placed in the magazine 502 . This is sometimes called half cocking.

Further, a user (not shown) starts to pull the hammer 20 in the air gun 500 having the above configuration to half-cock. As a result, the nozzle 50 begins to move slightly backward in the R direction, and the hose pressing portion 70 presses the hose portion 60 to further bend the hose portion 60 connected to the nozzle 50 .

As described above, when the nozzle 50 starts to move in the rearward R direction, the hose portion 60 has elasticity, which may hinder the movement due to the half-cocking. In this case, since the hose roller portion 71 of the hose pressing portion 70 is pressed from the rear R direction to the front F direction by the hose spring 72, the hose roller portion 71 is pushed against the elastic force of the hose portion 60. It acts to bend the portion 60 from the rear R direction to the front F direction, and counters the elastic force. As a result, even if the hose portion 60, which does not exist in the actual gun, is provided, the hose pressing portion 70 acts to cancel the elastic force against the bending force of the hose portion.

In order to maintain this half-cocked state, the trigger 700 engages the trigger first engaging portion 28 on the hammer 20 . At this time, the connecting rod 80 connected to the hammer 20 pushes down the piston 570 and accumulates pressure in the spring 580 .

Next, the user (not shown) further pulls the hammer 20 . As a result, the hammer rotating portion 24 rotates, the engaging portion 22 rotates in the rearward R direction, and the engaging portion 22 engages with the hammer parts engagement receiving portion 32, whereby the hammer parts engagement receiving portion 32 is engaged. The portion 32 also rotates in the backward R direction.

The rotation of the hammer part engagement receiving portion 32 causes the hammer part engagement receiving portion 32 to engage with the one end portion 41 of the nozzle cam 40 , so that the one end portion 41 of the shaft portion 600 attached to the air gun 500 rotates. It rotates around and the other end 42 moves forward in the F direction. The other end 42 is connected to the nozzle 50 so that the nozzle 50 presses against the cartridge 100 placed in the magazine 502 , and the nozzle 50 presses the cart inner 120 in the cartridge 100 placed in the magazine 502 . At this time, the nozzle 50 presses only the cart inner 120 of the cartridge 100 placed in the magazine 502, so the magazine 502 itself is not pressed. Therefore, the magazine 502 does not move in the forward F direction unlike the conventional air gun.

In this way, when the nozzle cam 40 presses the nozzle 50 , the connecting rod 80 connected to the hammer 20 pushes the piston 570 further down and the spring 580 accumulates pressure. In this case, the piston 570 is completely pressure-accumulated by the compressed spring 580 and is in a so-called full-bottom state. This state is sometimes called full cocking.

In this fully cocked condition, magazine 502 is locked in rotation. Also, in order to maintain this fully cocked state, the trigger 700 disengages from the trigger first engaging portion 28 of the hammer 20 and engages with the trigger second engaging portion 29 . Additionally, as noted above, the nozzle 50 presses against the cart inner 120 of the cartridge 100 positioned within the magazine 502 .

As described above, the bullet B placed in the bullet holding portion 183 of the large diameter portion 180 is pushed out by the cart inner 120 and moves to the bullet placement portion 184 . Since the bullet B is placed in the bullet holding portion 184 when the bullet B is fired after being fully cocked in this way, the position where the bullet B is placed and the position of the pop-up portion 503 are different. It is always constant and does not decrease accuracy.

Further, in this fully cocked state, the cart inner 120 moves forward in the F direction so as to compress the cart spring 130 . As a result, when the bullet lock 150 engaged with the groove portion 125 moves forward in the F direction, pressure is accumulated in the bullet spring 160 . The bullet portion 170 moves in the forward direction F due to this accumulated force, and the tapered slope portion 181a comes into close contact with the chamber packing 501a arranged at the rear end of the barrel passage 501, thereby ensuring airtightness. Therefore, the risk of compressed air leaking from between the sloped portion 181a and the barrel passage 501 is reduced.

Further, even if the nozzle cam 40 presses the nozzle 50, the nozzle 50 presses the cart inner 120 of the cartridge 100 arranged in the magazine 502, so the magazine 502 itself does not move forward in the F direction. Unlike conventional air guns, the air gun 500 of this embodiment can provide a feeling of operation similar to that of a real gun.

Next, when the user (not shown) pulls the trigger 700 in this fully cocked state, the engagement between the trigger 700 and the second trigger engaging portion 29 of the hammer 20 is released. At that time, as the compressed spring 580 returns to its natural length, the piston 570 is pushed up to generate compressed air. The generated compressed air is supplied to the nozzle 50 through the hose portion 60, and the compressed air is injected into the cartridge 100 arranged in the magazine 502. to fire.

At this time, since the action of pulling the trigger 700 is only to release the engagement between the trigger 700 and the second trigger engaging portion 29 of the hammer 20, no extra force is applied. It is also possible to realize a motion of pulling the trigger 700 that does not resemble a real gun. This ensures that once the target is set, it does not shift, and furthermore, it is possible to reduce the risk of a drop in accuracy as much as possible.
