Description

Technical Field

[0001] The present invention relates to an air gun cartridge used for an air gun capable of firing a bullet, and an air gun using the cartridge.

Background Art

[0002] Among air guns capable of firing bullets, there is a revolver type, and a method is adopted in which BB bullets are loaded into a so-called cylindrical cartridge and used. For example, an invention related to a cartridge for a toy gun for an air gun capable of obtaining a good hop-up effect in order to improve hitting accuracy is disclosed in Japanese Patent Application Laid-Open No. 2014-222135.

[0003] The above invention is a cartridge for a toy gun used for a toy gun capable of firing a bullet, and has a cylindrical structure in which the inside is a flow path of compressed air, and a main body through which compressed air flows from an inlet at the rear end to an outlet at the front end, and a bullet holding portion having a structure for loading and holding a bullet on the outlet side of the front end of the main body. The bullet holding portion is configured to hold the bullet so as not to escape, and to fire the bullet when a pressure of compressed air greater than the holding force is applied.

[0004] Since this cartridge loads and holds the bullet at the front end of the main body close to the hop-up portion, it can obtain a sufficient hop-up effect, has excellent straightness, and has an effect of good hitting accuracy, and has also received high evaluation from the market.

[0005] However, although the BB bullet is held in the cartridge, the user has to insert and hold the BB bullet in the cartridge. Since the position where the BB bullet is held in the cartridge varies depending on the user, the distance from the pop-up portion for hop-up varies depending on the position, and there may be a difference in hitting accuracy.

[0006] On the one hand, it fires bullets by pressing the above-mentioned cartridge held in the magazine. In that case, the magazine holding the cartridge may also move forward. Thus, the forward movement of the magazine results in an operation different from that of a real gun, and the operating feel may be different from that of a real gun. Therefore, there is also a requirement to make the operating feel the same as that of a real gun.

Problems to be Solved by the Invention

[0008] The present invention has been made in view of the above circumstances, and the problem is to provide a cartridge for an air gun capable of arranging the position for holding bullets, which are BB bullets in the cartridge, at a predetermined position. Another problem is to provide an air gun in which the magazine does not move forward even when the cartridge is pressed.

Means for Solving the Problems

[0009] To solve the above problems, the cartridge according to the first aspect has a cartridge main body portion having a cylindrical shape, and a cartridge inner also having a cylindrical shape and arranged to be movable in the front-rear direction for pressing the bullet inside the cartridge main body portion having a cylindrical shape. When the bullet is arranged in front of the cartridge inner, by pressing the cartridge inner forward, the bullet moves forward.

[0010] In addition, the cartridge from the second perspective has a cartridge body portion that presents a cylindrical shape, and inside the cartridge body portion that presents a cylindrical shape, there is a cart inner that is arranged to be movable in the front-rear direction to press a bullet, presents a cylindrical shape, and has a groove portion on its outer periphery, a bullet lock that engages with the groove portion and moves forward as the cart inner moves forward, and a bullet portion that has a bullet placement portion for placing the bullet and that moves further forward as the bullet lock moves forward. The bullet is placed in front of the cart inner, and the bullet is placed in the bullet placement portion by pressing the cart inner forward.

[0011] In addition, the cartridge from the third perspective has a cartridge body portion that presents a cylindrical shape, and inside the cartridge body portion that presents a cylindrical shape, there is a cart inner that is arranged to be movable in the front-rear direction to press a bullet, presents a cylindrical shape, and has a groove portion on its outer periphery, a bullet lock that engages with the groove portion and moves forward as the cart inner moves forward, a bullet portion that has a bullet placement portion for placing the bullet and a stepped portion that forms a step and that moves further forward as the bullet lock moves forward, and a bullet spring that is arranged in front of the bullet lock and engages with the stepped portion. The bullet is placed in front of the cart inner, and the bullet is placed in the bullet placement portion by pressing the cart inner forward and pressing the bullet portion forward via the bullet spring.

[0012] In addition, the air gun from the fourth perspective has a cartridge from the third perspective that includes a bullet, a magazine for placing the cartridge, and a chamber packing that serves as a passage through which the bullet passes. The bullet portion in the cartridge further has a tapered inclined surface portion. When pressing the bullet portion in the cartridge placed in the magazine forward, the inclined surface portion presses against the chamber packing.

Advantages of the Invention

[0013] Since the present invention is configured and operates as described above, it is possible to provide a cartridge for an air gun that can position the holding position of BB bullets in the cartridge at a predetermined position. Further, it is possible to provide an air gun in which the magazine does not move forward even when the cartridge is pressed.

Best Mode for Carrying Out the Invention

[0015] Hereinafter, with reference to the illustrated embodiments, the cartridge 100 of this example will be described. The cartridge 100 of this example is for holding BB bullets which are bullets B, and as will be described later, by moving the held bullet B in the forward F direction, the bullet B is arranged in a bullet arrangement portion 184 which will be described later.

[0016] The cartridge 100 of this example has a cartridge main body portion 110 having a cylindrical shape, and a cartridge inner 120 which is arranged inside the cartridge main body portion 110 and has a cylindrical structure in which an inner diameter portion 127 described later serves as a flow path for compressed air. Hereinafter, when the cartridge 100 is viewed from the side, the direction from the rear end portion 111 of the cartridge main body portion 110 described later to the tip portion 185 in the bullet portion 170 is referred to as the forward F direction. Similarly, in the cartridge 100, the direction from the tip portion 185 in the bullet portion 170 described later to the rear end portion 111 of the cartridge main body portion 110 is referred to as the rearward R direction. Further, in a state where the cartridge 100 is loaded into the air gun 500, when the air gun 500 is viewed from the side, the direction from the piston cylinder device 550 to the muzzle 530 is referred to as the forward F direction. Similarly, the direction from the muzzle 530 to the piston cylinder device 550 is referred to as the rearward R direction.

[0017] The cartridge inner 120 is arranged to be movable back and forth inside the cartridge main body portion 110. Further, a cartridge spring 130 which is a coil spring is arranged between the cartridge main body portion 110 and the cartridge inner 120. As will be described later, the cartridge spring 130 biases the cartridge inner 120 in the rearward R direction with respect to the cartridge main body portion 110.

[0018] The cartridge main body 110 has a rear end portion 111, and the rear end portion 111 is open. Also, inside the cartridge main body 110, at a position slightly forward in the F direction from approximately the midpoint of the entire length, a main body protrusion 112 that protrudes inside in a rib shape so as to go around is arranged.

[0019] The cartridge inner 120 has a substantially hollow cylindrical shape, and from the rear R direction to the front F direction, it has a flange-shaped large-diameter portion 121, a central axis portion 122 with a smaller diameter than the large-diameter portion 121, and a thin axis portion 123 with a smaller diameter than the central axis portion 122, and they are integrally formed. The large-diameter portion 121 is arranged inside the rear end portion 111 of the cartridge main body 110 and has a diameter slightly smaller than the inner diameter of the rear end portion 111. In the cartridge 100, the central axis portion 122 of the cartridge inner 120 is arranged inside the cartridge spring 130, and the large-diameter portion 121 is arranged such that one end of the cartridge spring 130 contacts it, and the other end of the cartridge spring 130 contacts the main body protrusion 112 of the cartridge main body 110.

[0020] The thin axis portion 123 has a protruding portion 124 that is circular and protrudes outward in a rib shape, and a groove-shaped groove portion 125 is formed between the central axis portion 122 and the protruding portion 124. Also, the cartridge inner 120 has an inner diameter portion 127 that is the hollow portion of its substantially hollow cylindrical shape. The inner diameter portion 127 has a uniform diameter. As described above, this inner diameter portion 127 serves as a flow path for compressed air. Also, the thin axis portion 123 has a tip portion 123a at its tip. This tip portion 123a presses the bullet B as will be described later.

[0021] The bullet rock 150 having a cylindrical shape is attached to the cart inner 120, and a rib-shaped first protrusion 152 that is disposed at the rear end portion 151 of the bullet rock 150 and protrudes inward and circumferentially is arranged to engage with the groove portion 125 of the cart inner 120. Further, the bullet rock 150 has two second protrusions 156 that protrude inward at its tip end portion 155. The two second protrusions 156 are arranged with a 180-degree shift inside the bullet rock 150 having a cylindrical shape. Therefore, the second protrusions 156, 156 are arranged to protrude facing each other inside the bullet rock 150.

[0022] Note that the bullet rock 150 having a cylindrical shape in FIG. 2 is illustrated as being divided into semi-cylindrical bullet rock pieces 150a, 150b. The bullet rock pieces 150a, 150b each have the first protrusion 152 and the second protrusion 156. By assembling these semi-cylindrical bullet rock pieces 150a, 150b, the bullet rock 150 is constituted.

[0023] A bullet spring 160, which is a coil spring, is arranged so as to be in contact with the tip end portion 155 of the bullet rock 150. The bullet spring 160 is further in contact with a step portion 181 described later.

[0024] Also, the cartridge 100 has a bullet portion 170 inside its tip end. The bullet portion 170 has a small-diameter portion 175 having a hollow cylindrical shape and a large-diameter portion 180 having a hollow cylindrical shape. Although the inner diameters of the small-diameter portion 175 and the large-diameter portion 180 are the same, the outer diameters are different, and as the name implies, the bullet small-diameter portion 175 has a smaller outer diameter than the bullet large-diameter portion 180.

[0025] Additionally, the outside of the large diameter portion 180 in the bullet portion 170 has a tapered slope portion 181a. As described later, this ensures airtightness when it comes into close contact with a chamber packing 501a disposed at the rear end of the barrel passage 501. The chamber packing 501a is connected to the barrel passage 501, and together with the barrel passage 501, it forms a cylindrical passage through which the bullet passes.

[0026] The small-diameter bullet portion 175 and the large-diameter bullet portion 180 are integral with each other, and have a step portion 181 at the boundary between them. Also, the large-diameter bullet portion 180 has a bullet holder 183 for placing a bullet B therein.

[0027] The bullet holding portion 183 is configured to have a flexible rubber material attached to its inner circumferential surface so as to store the bullet B. It also has a bullet placement portion 184 for placing the bullet B in the forward direction F of the bullet holding portion 183. The large diameter portion 180 also has a tip portion 185 that opens at its tip. Inside the tip portion 185, the bullet placement portion 184 for placing the above-mentioned bullet B is placed.

[0028] Further, the bullet narrow diameter portion 175 is provided with long hole portions 177, 177 that are long in the front-rear direction. The bullet narrow diameter portion 175 has two of these long hole portions 177, 177. The two long hole portions 177, 177 are arranged circumferentially, shifted by 180 degrees, in the bullet narrow diameter portion 175 that has a cylindrical shape. Therefore, the long hole portions 177, 177 are arranged to face each other in the bullet narrow diameter portion 175. The long hole portions 177, 177 are arranged so that the above-mentioned second protrusion portions 156, 156 can slide in the front-rear direction. Therefore, the bullet portion 170 can move forward relative to the bullet lock 150 by the longitudinal distance of the long hole portions 177, 177.

[0029] Further, the cartridge 100 has the breech spring 160 which is a coil spring as described above. One end of the breech spring 160 is in contact with the tip 155 of the breech lock 150, and the other end is arranged to be in contact with the step 181 of the breech 170.

[0030] For the cartridge 100 configured as described above, a user (not shown) can insert the bullet B through the opening at the tip 185 thereof and place the bullet B in the bullet holding portion 183. However, the position where the user inserts and places it varies. Actually, the bullet B is placed at any position from the bullet holding portion 183 to the bullet placement portion 184.

[0031] Note that FIGS. 4A and 4B illustrate the state of the fully cocked cartridge 100, and the difference between FIGS. 4A and 4B is whether the bullet B is illustrated or not. In the cartridge 100 configured as described above, when the cart inner 120 arranged inside the cartridge body portion 110 is pressed in the forward F direction against the elastic force of the cart spring 130, the cart inner 120 moves in the forward F direction. At this time, the tip 123a of the thin shaft portion 123 of the cart inner 120 pushes out the bullet B arranged in the bullet holding portion 183 and moves the bullet B to the bullet placement portion 184.

[0032] Further, the breech lock 150 attached to the cart inner 120 moves in the forward F direction and compresses the breech spring 160.

[0033] The breech portion 170 in contact with the breech spring 160 moves in the forward F direction by the elastic force of the compressed breech spring 160.

[0034] At the tip 123a of the thin shaft portion 123 in the cart inner 120, the bullet B pushed forward is placed in the bullet placement portion 184 inside the bullet portion 170 that has moved in the forward F direction as described above. At this position, by placing the cartridge 100 having the bullet B in the cartridge chamber 502 described later and fully cocking it, the bullet B is positioned in the bullet placement portion 184, and the distance between this position and the hop-up portion 503 in the air gun 500 can be maintained. Therefore, when the bullet B is fired, an appropriate spin is applied to the bullet B and the hitting accuracy is not deteriorated.

[0035] Hereinafter, with reference to the illustrated embodiment, an air gun 500 that can use the above-described cartridge 100 will be described. The air gun 500 is preferably of a so-called revolver type. The barrel passage 501 is a passage through which the bullet B passes, and the cartridge chamber 502 can be loaded with the plurality of cartridges 100 (see, for example, FIG. 9) described above. Further, a hop-up portion 503 protruding into the barrel passage 501 in the rearward R direction of the barrel passage 501 is configured. The hop-up portion 503 gives a predetermined rotation to the bullet B moving at high speed to improve the hitting accuracy.

[0036] The cartridge 100 is for loading the bullet B. The bullet B is held in a fixed position until it is fired while the cartridge 100 is loaded in the cartridge chamber 502, and is fired from the muzzle 530 by compressed air ejected from the nozzle 50.

[0037] The nozzle 50 is disposed in the rearward R direction of the cartridge chamber 502, and the nozzle 50 is connected to the piston cylinder device 550 by a hose portion 60 formed of a pipe described later. The piston cylinder device 550 includes a cylinder 560 and a piston 570 disposed at the lower part of the grip portion of the gun body. Further, the piston cylinder device 550 has a spring 580 for accumulating pressure on the piston 570, and the spring 580 is disposed inside the piston 570.

[0038] In this embodiment, the cylinder 560 is fixed to the air gun 500, and the piston 570 is arranged slidably with respect to the cylinder 560 by the expansion and contraction force of the above-described spring 580. Further, the nozzle 50 further has a nozzle packing 51 in order to be in close contact with the cartridge 100 arranged in the cartridge chamber 502.

[0039] Also, the air gun 500 has a pressing device 10 that presses the nozzle 50 against the cartridge chamber 502 by the full cocking operation 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 cartridge chamber 502.

[0040] Also, the air gun 500 has an inner frame 650 that constitutes a kind of inner skeleton, and the pressing device 10 is arranged on the inner frame 650.

[0041] 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 performing a half cocking or full cocking operation as will be described later, and has a finger hook part 21 for a user (not shown) to place a finger on the hammer 20 and an engaging part 22 that engages with the hammer part 30. The hammer 20 is pivotally supported and attached to the air gun 500 so as to be rotatable with respect to the air gun 500 by a rotation shaft part 25.

[0042] When the hammer 20 is fully cocked, by engaging with the hammer 20, the hammer part 30 rotates, and by engaging with the hammer part 30, the above-mentioned nozzle cam 40 rotates, and as a result, the nozzle cam 40 presses the nozzle 50. In this way, by pressing the nozzle 50 against the cartridge 100 disposed in the magazine 502 by the pressing device 10, the nozzle 50 can be brought into close contact with the cartridge 100 disposed in the magazine 502 as described above, so that leakage of compressed air therefrom can be prevented. Further, since the hammer 20 is fully cocked to press the nozzle 50 against the cartridge 100 disposed in the magazine 502, the tightness 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 that of a real gun.

[0043] Further, the hammer 20 has a connecting rod connection part 23, and literally the connecting rod connection part 23 is connected to the connecting rod 80, and the connecting rod 80 is connected to the piston cylinder device 550. Specifically, the connecting rod 80 is connected to a piston connection part 571 which is a part of the piston 570, and when the hammer 20 is pulled, the piston 570 is pushed down through the connecting rod 80 to accumulate the spring 580.

[0044] Further, the hammer 20 has a hammer rotation part 24 having a circular shape in plan view, and the above-mentioned engaging part 22 is disposed so as to protrude from the rotation part 24. Also, both the finger hook part 21 and the engaging part 22 are disposed so as to protrude from the rotation part 24. Therefore, in the uncocked state, the hammer part engagement receiving part 32, which will be described later, is disposed near the one-end engaging part 21a, and immediately before full cocking, the hammer part engagement receiving part 32 engages with the engaging part 22. Further, the rotation axis part 25 is provided at the center of the hammer rotation part 24, and the rotation axis part 25 is pivotally supported so as to be rotatable when a cocking operation is performed on the hammer 20.

[0045] Further, the hammer 20 has a first trigger engaging portion 28 that engages with the trigger 700. The first trigger engaging portion 28 has a stepped shape with a missing hammer rotating portion 24 that is substantially circular in plan view. Also, the hammer 20 has a second trigger engaging portion 29 that engages with the trigger 700. The second trigger engaging portion 29 has a stepped shape with a missing part of the hammer rotating portion 24 that is substantially circular in plan view. Both the first trigger engaging portion 28 and the second trigger engaging portion 29 are provided as parts of the hammer rotating portion 24.

[0046] The hammer part 30 has a hammer part rotating portion 31 that is circular in shape and a hammer part engaging receiving portion 32 that protrudes from the hammer part rotating portion 31. The center of the hammer part rotating portion 31 is coaxially and rotatably supported by the center of the hammer rotating portion 24 and the rotating shaft portion 25.

[0047] The hammer part engaging receiving portion 32 literally engages with the above-described engaging portion 22. When the hammer 20 is cocked, the hammer rotating portion 24 rotates, and the engaging portion 22 rotates. When the engaging portion 22 engages with the hammer part engaging receiving portion 32, the hammer part engaging receiving portion 32 also rotates.

[0048] Also, the nozzle cam 40 has one end portion 41, the other end portion 42, and a rotating portion 43 therebetween. The rotating portion 43 is rotatably supported by a shaft portion 600 attached to the air gun 500, and the one end portion 41 and the other end portion 42 are pivotally supported so as to be swingable like a seesaw. Also, the one end portion 41 presses the other end portion 42 in the direction of the muzzle 530 (front F direction) by engaging with the hammer part engaging receiving portion 32.

[0049] Also, one end portion 41 of the nozzle cam 40 is biased by a nozzle cam spring 45 to rotate in the rearward R direction. As a result, the other end portion 42 connected to the nozzle 50 is biased to be separated from the cartridge 100 disposed in the magazine portion 502 of the nozzle 50.

[0050] One end portion 41 of the nozzle cam 40 is arranged to engage with an end engaging portion 21a disposed near the root of the finger-hooking portion 21 of the hammer 20. In this way, by engaging with the end portion 41 of the nozzle cam 40, the end engaging portion 21a presses the nozzle cam 40 slightly forward in the F direction so as to counteract the pressing force of the nozzle cam spring 45.

[0051] Also, as described above, the nozzle 50 is connected to a hollow hose portion 60. The hose portion 60 is connected to a cylinder 560 and is for sending out the compressed air generated by the piston-cylinder device 550 to the nozzle 50. The hose portion 60 is preferably made of a flexible synthetic resin.

[0052] Further, even if the hose portion 60 is made of a flexible synthetic resin, it may have a certain degree of rigidity in order to prevent the hose portion 60 from being crushed. For this purpose, it has a hose pressing portion 70 for pressing to so-called buckle the hose portion 60. 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, since the hose pressing portion 70 pushes out the hose portion 60 in the front F direction, it is disposed in the rear R direction of the hose portion 60. Also, in this embodiment, the position where the hose pressing portion 70 presses the hose portion 60 is preferably arranged at an intermediate point between the cylinder device 550 and the nozzle 50. This is because, at that position, when applying a pressing force that causes the hose portion 60 to bend, the force becomes relatively small.

[0053] In FIGS. 5 to 12, the state in which a user (not shown) pulls the hammer 20 will be described. Here, FIGS. 5 and 6 show the state before pulling the hammer, FIGS. 9 and 10 show the half-cocked state, and FIGS. 11 and 12 show the fully-cocked state. Also, the state of the cartridge 100 in FIGS. 9 and 10 is shown in FIGS. 3A and 3B. Further, the state of the cartridge 100 in FIGS. 11 and 12 is shown in FIGS. 4A and 4B.

[0054] A user (not shown in advance) stores the bullet B in the bullet holding portion 183 in the cartridge 100. At this time, if the user (not shown) inserts the bullet B from the bullet holding portion 183 to the position of the bullet placement portion 184, there is no particular problem. That is, when the user (not shown) fully cocks the gun, the bullet B stored at any position from the bullet holding portion 183 to the bullet placement portion 184 is pushed out by the cartridge inner 120 and moves to the bullet placement portion 184 and is placed there.

[0055] In this way, when it is fully cocked and the bullet B is in a state where it can be fired, the bullet B has moved from the bullet holding portion 183 and is placed in the bullet placement portion 184. Therefore, the position of the bullet B and the position of the popup portion 503 are always constant. Even if the user inserts the bullet B and there is a misalignment, the hitting accuracy will not deteriorate. This is because the bullet B is pushed out by the cartridge inner 120 and moves to the bullet placement portion 184 (see FIGS. 4A, 4B, 11, and 12).

[0056] A user (not shown) starts to pull the hammer 20 in the air gun 500 having the above-described configuration. Before the user (not shown) pulls the hammer 20, the pressing device 10 presses the cartridge 100 disposed in the magazine 502 with the nozzle 50. However, when the user (not shown) starts to pull the hammer 20, the engagement between the one-end engaging portion 21a and the one end 41 is released, the nozzle cam 40 rotates in the rearward R direction, the other end 42 of the nozzle cam 40 rotates, and by moving slightly in the rearward R direction, the nozzle 50 connected to the other end 42 thereof moves in the rearward R direction, and a gap is generated between the nozzle 50 and the cartridge 100 disposed in the magazine 502. This may be referred to as half-cocking.

[0057] Also, a user (not shown) starts to pull the hammer 20 in the air gun 500 having the above-described configuration and performs half-cocking. As a result, the nozzle 50 starts to move slightly in the rearward R direction, and the hose pressing portion 70 presses the hose portion 60 connected to the nozzle 50 in an attempt to further bend the hose portion 60.

[0058] As described above, when the nozzle 50 starts to move in the rearward R direction by half-cocking, the hose portion 60 may inhibit the movement because it has elasticity. In this case, the hose roller portion 71 in the hose pressing portion 70 is pressed from the rearward R direction to the forward F direction by the hose spring 72, and thus acts to bend the hose portion 60 from the rearward R direction to the forward F direction so as to counteract the elastic force of the hose portion 60, and is a countermeasure against the elastic force. Accordingly, even if there is a hose portion 60 that does not exist in a real gun, the hose pressing portion 70 acts to cancel the elastic force against the force that attempts to bend the hose portion.

[0059] In order to maintain this half-cocked state, the trigger 700 engages with the trigger first engaging portion 28 in the hammer 20. At this time, the connecting rod 80 connected to the hammer 20 pushes down the piston 570 and accumulates the spring 580.

[0060] Next, a user (not shown) further pulls the hammer 20. As a result, the hammer rotating portion 24 rotates, and the engaging portion 22 rotates in the rearward R direction. When the engaging portion 22 engages with the hammer part engaging receiving portion 32, the hammer part engaging receiving portion 32 also rotates in the rearward R direction.

[0061] Due to the rotation of the hammer part engaging receiving portion 32, the hammer part engaging receiving portion 32 engages with one end portion 41 of the nozzle cam 40, causing the one end portion 41 to rotate around the shaft portion 600 attached to the air gun 500, and the other end portion 42 to move in the forward F direction. Since the other end portion 42 is connected to the nozzle 50, the nozzle 50 is pressed against the cartridge 100 disposed in the magazine 502, and the nozzle 50 presses the cart inner 120 of the cartridge 100 disposed in the magazine 502. At this time, the nozzle 50 only presses the cart inner 120 of the cartridge 100 disposed in the magazine 502, so the magazine 502 itself is not pressed. Therefore, the magazine 502 does not move in the forward F direction like a conventional air gun.

[0062] In this way, when the nozzle cam 40 presses the nozzle 50, the connecting rod 80 connected to the hammer 20 further pushes down the piston 570 to accumulate the spring 580. In this case, the piston 570 is completely accumulated by the compressed spring 580 and is in a so-called full bottom state. This state may be referred to as full cocking.

[0063] In this full cocking state, the rotation of the magazine 502 is fixed. Also, in order to maintain this full cocking 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. Further, as described above, the nozzle 50 presses the cart inner 120 of the cartridge 100 disposed in the magazine 502.

[0064] As described above, the bullet B placed in the bullet holding part 183 in the large-diameter part 180 is pushed out to the cart inner 120 and moves to the bullet placement part 184. When it is fully cocked and in the state of firing the bullet B, since the bullet B is placed in the bullet holding part 184, the position of the bullet B and the position of the popup part 503 are always constant, and the hitting accuracy does not decrease.

[0065] Also, in this fully cocked state, the cart inner 120 moves in the forward F direction so as to compress the cart spring 130. As a result, when the brett lock 150 engaged with the groove part 125 moves in the forward F direction, the brett spring 160 is accumulated. With this accumulated pressure, the brett part 170 moves in the forward F direction, and the tapered slope part 181a comes into close contact with the chamber packing 501a arranged at the rear end of the barrel passage 501, and airtightness can be ensured. Therefore, the possibility of compressed air leaking from between the slope part 181a and the barrel passage 501 is small.

[0066] Also, even when the nozzle cam 40 presses the nozzle 50, the nozzle 50 presses the cart inner 120 in the cartridge 100 arranged in the magazine 502. Therefore, the magazine 502 itself does not move in the forward F direction. Different from the conventional air gun, the air gun 500 of this embodiment can obtain the same operating feeling as a real gun.

[0067] Next, in this fully cocked state, when a user (not shown) pulls the trigger 700, the engagement between the trigger 700 and the second trigger engagement part 29 in 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 part 60, and the compressed air is injected into the cartridge 100 arranged in the magazine 502, and the injection fires the bullet B through the inner diameter part 127 and the bullet placement part 184.

[0068] At this time, since the operation of pulling the trigger 700 only releases the engagement between the trigger 700 and the second trigger engaging portion 29 in the hammer 20, no extra unnecessary force is applied, and it is possible to realize the operation of pulling the trigger 700 that is the same as that of a real gun without any color. As a result, the aiming determined once will not be displaced, and the risk of further reduction in hitting accuracy can be reduced as much as possible.
