Description

  The present invention relates to a detachable gas tank that is attached to a gun body in a simulated gun that fires bullets by gas pressure.

  A gas gun that fires bullets by gas pressure, along with an electric gun and an air cocking gun, plays a part of a simulated gun. The gas gun has a tank for storing a predetermined amount of liquefied gas, and is fired by using the pressure of the gas vaporized on the liquid surface. The bullet is ejected by gas by a firing mechanism. In gas guns, therefore, it is desirable that the vaporized gas is injected into the firing mechanism in the required amount, and if the gas is released or the liquefied gas is leaked without being vaporized, the gas consumption is reduced. This increases the so-called fuel consumption.

  On the other hand, the invention of Japanese Patent Laid-Open No. 8-278097 prevents the liquefied gas from leaking toward the firing mechanism of the gun body when the attitude of the gas gun changes when the liquefied gas is injected and in use. It has the purpose of doing. In the invention of the same issue, the inside of the tank is divided into a main chamber portion and a sub chamber portion, and a pipe for gas injection is arranged from the tank bottom portion to the main chamber portion, and gas is blown out from the sub chamber portion at a position facing the bottom portion. The pipe for this purpose is arranged in the main chamber, and both pipes are alternately faced at the end.

  In the above invention, when the gas outlet passage portion is opened, only the gas obtained by vaporizing the liquefied gas in the pressure accumulating chamber is maintained in a state of being supplied to the pressure chamber in the toy gun body through the gas outlet passage portion. It is made in view of the fact that it is desirable. However, for that purpose, the inside of the tank is divided into a main chamber portion and a sub chamber portion, and a pipe is provided as a gas passage in the partition wall, so that a very complicated structure is required. In addition, since the gas lead-out passage part is configured to face the bottom part of the case (tank), it is difficult to apply it to other simulated guns, regardless of the tank such as a hand gun in which the gas injection hole is located below. It is.

JP-A-8-278097

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a detachable gas tank in a simulated gun that has a simple structure and does not leak liquefied gas. Another subject of the present invention is suitable for a simulated gun in which the tank body is attached to the gun body by an insertion operation in the direction of the barrel, and the gun body is directed downward or upward. Another object is to provide a detachable gas tank in a simulated gun in which liquefied gas is difficult to leak into the gas passage of the gun body.

In order to solve the above-described problems, the present invention provides a simulated gun that fires a bullet by the pressure of a gas. As a detachable gas tank to be attached to the gun body , the tank body has a gas ejection part. The outer end of the tank and the outer end of the gas injection section are facing upward, and the liquefied gas is injected in this state, and the upper part of the tank body is in a standard state with the barrel oriented almost horizontally. And a gas injection part located below the gas injection part of the tank body, and the gas injection part has a gas injection pipe oriented substantially horizontally in the standard state. In addition, it has an injection valve for gas injection, and the gas injection part has a gas injection pipe that is also oriented almost horizontally in the standard state, and closes when not mounted on the gun body, and opens and closes when mounted Have Ri, in the same side of both the tank body and the gas ejection pipe and a gas injection pipe, the inner end of the gas injection pipe is located inward from the inner end of the gas injection pipe, the barrel In the upward injection state, the liquefied gas reaches the vicinity where it touches the inner end of the gas injection part beyond the inner end part of the gas injection part, becomes full, and the standard state with the barrel oriented almost horizontally in one in which the liquid surface at the time of full of liquefied gas took measures that configured to be located in the middle of the gas injection portion and the gas ejection portion.

  In the configuration of the present invention, the state in which the barrel is oriented almost horizontally is described as the standard state. However, in view of the fact that the orientation of the tank changes depending on the barrel direction, the posture in which the barrel is oriented almost horizontally is the most common. It is described as a standard state as a special shooting posture. Therefore, the word “standard state” has no special meaning other than the above. It should be noted that the state in which the barrel is directed downward is referred to as downward, the state in which the barrel is directed upward is also referred to as upward, and the state in which the barrel is horizontal but the gun body is upside down may be referred to as reversed.

  In the above configuration, the gas injection part has a gas injection pipe, and the gas injection part has been described as having a gas injection pipe. In this case, the term “pipe” is a passage of liquefied gas or vaporized gas. Used in meaning. Therefore, it is not necessarily intended to be limited to only a pipe structure or only a tubular structure, and when limited to a pipe structure, it is described as a pipe structure and distinguished. The reason is that when a plastic molded product is used for the tank body or a part thereof, a gas passage can be formed as a part of the molding structure, which can be said to be a gas passage or a pipe.

  Both the gas injection pipe and the gas injection pipe have a tubular structure, and in the standard state where the barrel is oriented almost horizontally, the outer end of the gas injection part and the outer end of the gas injection part Are open on the same side surface of the tank body and are arranged side by side in the vertical direction, which is desirable for the present invention.

  The tank body is a type in which liquefied gas is injected with the outer end of the gas ejection part and the outer end of the gas injection part facing upward, and the inner end of the gas injection pipe is the gas injection pipe. By being located inward from the inner end, the inner end of the gas ejection pipe is immersed in the liquefied gas during maximum injection, but is exposed on the liquid surface of the liquefied gas in the standard state and ejects the vaporized gas. Thus, the configuration is preferred for the present invention. In addition, "inward" when the inner end of the gas ejection pipe is located inward from the inner end of the gas injection pipe is said to have entered the interior as viewed from the pipe mounting part. Meaning. As a result, the tip of the pipe may approach the opposite side surface, but in the present invention, it is important how far it protrudes inward, and where it is close is not a problem.

  The tank body is a detachable type that is attached to the gun body by an insertion operation in the barrel direction. That is, it is also desirable for the present invention that the outer end portion of the gas ejection portion is disposed on the front surface in the insertion direction so that the gas ejection pipe and the gas passage on the gun body side are communicated by the insertion operation. .

  Since the present invention is configured and operates as described above, the structure is simple, and the detachable type in the simulation gun that does not leak the liquefied gas no matter which direction the gun body faces. There exists an effect that a gas tank can be provided. In addition, according to the present invention, it is suitable for a simulated gun of a type in which the tank body is attached to the gun body by an insertion operation in the direction of the barrel, and even if the gun body is directed downward or upward, It is possible to provide a removable gas tank in a simulated gun in which liquefied gas hardly leaks into the gas passage of the gun body.

  Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments. FIG. 1 shows a gun body 11 of a simulated gun 10 to which a detachable gas tank according to the present invention is applied, and this gun body 11 belongs to a type of gas gun capable of simultaneously firing a large number of spherical bullets.

Reference numeral 13 denotes a floor tail cover, and reference numeral 14 denotes a gas flow path (FIG. 1 is a schematic diagram) provided on the gun body side.

  The basic configuration of the gas gun will be described with reference to FIG. The gas flow path 14 is provided in the gun body 11, and the end thereof reaches a plurality of barrels 15. The gas flow path 14 has an air chamber 17 that is opened and closed by a valve body 16 in the middle thereof, and further has a flow rate adjusting unit 18 adjacent to the loading unit 15 a side of the barrel 15 on the downstream side. . The portion 11 a having the air chamber 17 is provided on the gun body 11 side, and springs 19 a and 19 b are disposed between the control valve device 25 described later.

  The valve body 16 is a shaft-like member, the front end portion 16 a enters the gas flow path inside the valve hole 17 a opened in the front partition wall of the air chamber 17, and the rear end portion 16 b is the air chamber 17. It protrudes rearward from a shaft hole 17b opened in the front partition, is mounted on the gun body 11 so as to be movable in the front-rear direction, and is biased by a spring 19b. Further, a protrusion 16c is provided on the outer periphery of the valve body 15 on the rear side of the intermediate portion, and the protrusion 16c can be stopped at the rear wall of the air chamber and the air chamber 17 is hermetically sealed. To do. On the other hand, the gun body 11 has a trigger 20, and the trigger 20 is provided so as to be rotatable about a shaft 20a, and is configured to open the valve body 16 via a shear 21 and a striker 22 by a firing operation. Has been.

  The shear 21 is provided so as to be rotatable around a shaft 21 a and has an engaging counterpart 21 b that engages with an engaging portion 20 b provided on the trigger 20. The striker 22 is attached to the guide shaft 23 provided in the gun body 11 so as to be movable in the front-rear direction and biased forward by a spring 23a. The rear end portion 16b is configured to be pressurized. While the trigger 20 and the shear 21 are engaged, the shear 21 is also engaged with the part 22c of the striker 22 at the part 21c, and therefore the striker 22 is placed at the standby position. FIG. 2 shows a moment when the trigger 20 is pulled and the engagement between the portion 21 c of the shear 21 and the portion 22 c of the striker 22 is disengaged and the striker 22 strikes the valve body 16. The trigger 20 and the shear 21 are provided with a return spring.

  The flow rate adjusting unit 18 includes a control valve device 25. The control valve device 25 includes a space 24 that communicates with the gas flow path 14, a gas ejection path 26 that communicates with the above-described space 24 on the upstream side, and a gas ejection path 26 that communicates with the loaded portion 14 a on the downstream side. 26 and a control valve 27 slidably inserted in 26. The gas ejection passages 26 are provided at three locations as in the case of the bullet loading portion 15 a, and the control valve 27 is urged in the valve closing direction by the coil spring of the urging means 28 arranged in each of the gas ejection passages 15 a, Can hit the portion 24a. The portion constituting the flow rate adjusting unit 18 has a gas injection nozzle 18a at the tip, and is provided so as to be movable in the front-rear direction with respect to the gun body 11, and constitutes a part of the bullet loading mechanism. Yes.

  The control valve 27 has a hollow cylindrical structure that is open on the barrel side and substantially closed on the upstream side, and has a side opening 27a and a small end surface as ventilation means for allowing gas to pass through an intermediate portion of the cylindrical structure. And an opening 27b. Accordingly, even when the control valve 27 enters the gas ejection path 26 to a part of the opening 27a with the bullet firing, and the flow of the gas flowing into the barrel is restricted, the small amount of gas is small. It can pass through the opening 27b. On the other hand, the spherical bullet B is supplied from the cartridge 29 attached to the lower part of the gun body 11 to the bullet loading portion 15 a side of the barrel 15.

  The tank body 30 is a device serving as a gas source of the gas gun, and includes a gas injection unit 31 for filling the inside with a liquefied gas, and a gas ejection unit for supplying the stored vaporized gas to the gas flow path 14. 35. As shown in detail in FIG. 3, the tank body 30 in the embodiment is a detachable type that is attached to the gun body 11 by an insertion operation in the barrel direction, and the gas ejection part 35 and the gun body are mounted by the insertion operation. The outer end portion of the gas ejection portion 31 is arranged on the front surface in the insertion direction so as to communicate with the gas flow channel 14 on the side.

  The gas injection part 31 has a gas injection pipe 32 oriented substantially horizontally in the standard state, and also has an injection valve 33 for gas injection. The injection valve 33 is housed inside the gas injection pipe 32. It has been. The gas injection pipe 32 has a pipe (that is, the outer shape is tubular) structure, and forms a part of the structure of the tank body 30. Further, the tank body 30 of the embodiment is a flat box shape formed by plastic molding, with the front surface in the insertion direction closed and the rear surface opened, and the opened rear surface is completely closed by the closing plate 34.

  The gas ejection part 35 has a gas ejection pipe 36 that is oriented almost horizontally in the standard state, and has a movable on-off valve 37 that closes when the gun body 11 is not mounted and opens when the gun body 11 is mounted. . The on-off valve 37 includes a valve case 37a incorporated in an outer end portion, a movable valve 37b disposed inside the valve case 37 so as to be movable in the pipe axis direction, and a spring 37c that urges the movable valve 37b in the valve closing direction. In addition, the gas flow is opened and closed depending on the position of a sealing member 37f disposed immediately before the gas passage hole 37d.

  In the present invention, the gas ejection pipe 36 and the gas injection pipe 32 are both on the same side surface of the tank body 30, and the inner end portion 36 e of the gas injection pipe 36 is more than the inner end portion 32 e of the gas injection pipe 32. Is also arranged to be located inward. That is, as shown in FIG. 3A, the inner end portion 36e of the gas ejection pipe 36 is more inward than the inner end portion 32e of the gas injection pipe 32 by a distance d as seen from each pipe mounting portion. I'm stuck in.

  Inside the mounting chamber 12 in which the tank main body 30 is mounted, there is an inner wall portion 38 that receives the tank main body 30, and a valve opening nozzle so that the gas ejection portion 35 and the gas flow path 14 on the gun main body side communicate therewith. 39 is provided (see FIG. 3B). The tip 39e of the valve opening nozzle 39 is formed in a reverse taper shape, and the movable end portion 37e of the on-off valve 37 is formed in a taper shape so as to engage with each other. When the gas ejection part 35 and the gas flow path 14 on the gun body side are connected, the movable valve 37b is pushed in and the airtight connection state is established, and the upper and lower parts of the front surface of the tank body 30 are the receiving parts 38a. 38b and enter a stable state (see FIG. 4).

  According to the present invention configured as described above, the following operation can be obtained. First, when the liquefied gas 40 is filled, the front surface in the insertion direction of the tank main body 30 is turned upward (see FIG. 5). In this state, when the gas cylinder nozzle is inserted into the gas injection part 31 and gas is injected, the liquefied gas 40 is filled up to the vicinity of the inner end part 32e of the gas injection pipe 32 and is filled up. When the tank main body 30 filled with the liquefied gas 40 is filled in the gun main body 11, the liquid level of the liquefied gas 40 is such that the gas injection pipe 32 is immersed in the standard state where the barrel 15 is oriented almost horizontally. Position (see FIG. 6).

Therefore, in this state, the gas ejection part 35 is located at the upper part of the tank main body 30, and it is clear that the gas injection part 31 is located below the gas ejection part 35 of the tank main body 30 in the standard state. That is, since the gas ejection pipe 36 is completely in the region of the vaporized gas 41, the bullet is fired normally with the intended pressure, and there is no possibility that the liquefied gas 40 flows out to the gas flow path 14. Therefore, the liquefied gas 40 is not leaked unnecessarily, and the so-called fuel consumption is kept good as designed. The tank body 30 has an inclined bottom surface 30a with the lower surface on the front side in the insertion direction facing the front, and the liquid level when filled to the middle position of the tank body 30 at the time of injection is the tank body in the standard state. Since it comes above the middle part of 30, it seems that a larger amount of liquefied gas 40 can be stored.

  FIG. 7 shows a state in which the barrel is turned downward. This downward state is a state that appears when the gas gun is hung on the shoulder using a shoulder belt. In the downward state, even if the liquefied gas 40 is full, the inner end 36e of the gas ejection pipe 36 is higher than the liquid level. For this reason, it is unlikely that only the vaporized gas 41 flows into the gas jet pipe 36 and the liquefied gas 40 leaks out. Therefore, the liquefied gas 40 does not accumulate in the gas flow path 14.

Further, when the gun barrel is horizontal but the gun body 11 is turned upside down, the liquid level is lowered by the amount of the inclined bottom surface 30a as compared with the case where the gun barrel is in the same standard state as the horizontal (see FIG. 8). For this reason, since both the gas injection part 31 and the gas ejection part 35 are submerged below the liquid level of the liquefied gas 40, the liquefied gas 40 may flow out to the gas flow path 14. However, according to the present invention, there is an on-off valve 37 between the tank main body 30 and the gas flow path 14 of the gun main body 11, and the amount of liquefied gas that can flow out is very limited. Gas) does not flow out to the gas flow path 14, and it is possible to prevent a situation such as deterioration of fuel consumption or abnormal bullet firing.

  Thus, since the apparatus of the present invention hardly leaks the liquefied gas to the mechanism inside the gun body, it is possible to prevent the gas fuel consumption from being deteriorated. In particular, according to the configuration of the present invention, in the standard state, the gas ejection pipe 36 is oriented substantially horizontally, has the gas injection part 31 on the same side surface, and the gas flow path in the substantially extending direction of the gas ejection part 35. 14 can be suitably applied to a gas gun provided with a configuration connected to 14.
