Description

Simulated gun disassembly type gas storage tank

The present invention relates to a removable gas storage tank mounted to a gun body in a simulated gun that emits a bullet by a pressure of a gas.

The air gun that fires the bullet by gas pressure is combined with the electric gun and the air firing gun to form part of the simulated gun. The air gun has a tank in which a predetermined amount of liquefied gas is accumulated, and is emitted by the pressure of the gas vaporized on the liquid surface, so that the emission of the bullet is performed by the gas emitted from the launching mechanism. Therefore, in the air gun, it is desirable to inject only a required amount of gasification gas to the launching mechanism, and if the gas is released without performing the emission operation, or if the liquefied gas leaks in the unvaporized state, the gas consumption increases, resulting in so-called fuel consumption. Deterioration.

In this regard, the invention of Japanese Patent Laid-Open No. Hei 8-278097 has an object of preventing the liquefied gas from leaking toward the launching mechanism side of the gun body when the posture of the air gun changes during the injection of the liquefied gas and the use state. In the same invention, the inner portion of the tank is a main chamber portion and a sub chamber portion, and a tube for injecting gas is disposed from the bottom of the tank to the main chamber portion, and a sub chamber located at a position opposed to the bottom portion is provided. The main chamber is provided with a tube for ejecting gas, and the two tubes are opposed only at the ends.

The above-mentioned invention is completed in view of the fact that, when the gas discharge passage portion is in an open state, it is desirable to maintain a state in which only the gas obtained by vaporizing the liquefied gas in the pressure accumulation chamber passes through the gas discharge passage portion. And supplied to the pressure chamber of the toy gun body. However, for this purpose, the inside of the tank is divided into a main chamber portion and a sub-chamber portion, and a pipe as a gas passage is provided on the partition wall, which requires a very complicated structure. Further, since the gas discharge passage portion is configured to face the bottom of the casing (tank), it is difficult to apply it to a simulation gun other than the tank of the pistol or the like in which the gas injection hole is located at the lower portion.

Patent Document 1: Japanese Patent Publication No. Hei 8-278097

The present invention has been made in view of the above-described actual circumstances, and an object of the present invention is to provide a removable gas storage tank of a dummy gun which has a simple structure and does not leak liquefied gas. Further, another object of the present invention is to provide a disassembled air tank for a simulated gun which is suitable for use in a simulation gun in which a can body is attached to a gun body by an insertion operation substantially in the direction of the gun body, even if With the gun body facing down or upward, the liquefied gas is also difficult to leak out of the gas passage of the gun body.

In order to solve the above problems, the present invention is a detachable gas storage tank that is attached to a gun main body in a simulation gun that emits a bullet by a gas, and has a gas ejection portion that is oriented substantially toward the gun body. In the horizontal standard state, the upper portion of the tank body is located; and the gas injection portion is located lower than the gas discharge portion of the tank body in the same state, and the gas injection portion has a substantially horizontal orientation in the standard state. a gas injection pipe having an injection valve for gas injection, the gas discharge portion having a gas discharge pipe that is substantially horizontal in the standard state, and an opening and closing valve that is closed when not attached to the gun body and opened at the time of installation, the gas Both the discharge pipe and the gas injection pipe are located on the same side surface of the tank main body, and the inner end portion of the gas discharge pipe is disposed at a position further inside than the inner end portion of the gas injection pipe.

In the configuration of the present invention, the posture in which the gun body is substantially horizontal is described as a standard state, which is a phenomenon in which the direction of the can body is changed in accordance with the direction of the gun body, and the posture in which the gun body is substantially horizontal is regarded as the most common shot. The posture is described as a standard state. Therefore, the term "standard state" has no special meaning other than the above. In addition, the state in which the gun body is facing downward is sometimes referred to as downward, and the state in which the upward direction is upward is referred to as upward, and the state in which the gun body is horizontal but the gun body is turned upside down is referred to as the reverse direction.

In the above configuration, it has been described that the gas injection portion has the injection pipe, and the gas discharge portion has the gas discharge pipe. However, the term "tube" at this time is used as a passage for the liquefied gas or the vaporized gas. Therefore, the purpose is not limited to the tube structure or the tubular structure, and when it is limited to the tube structure, it is described as a tube structure, and the difference is that the plastic molded article can be used as a can body or a part thereof. One part of the structure forms a gas passage, which may also be referred to as a gas passage or tube.

Both the gas injection pipe and the gas discharge pipe have a tubular structure and will be In the standard state in which the gun body is substantially horizontal, the outer end portion of the gas ejecting portion and the outer end portion of the gas injecting portion are opened to the same side surface of the can body, and are arranged in an upward and downward direction. This structure is preferable for the present invention.

The tank main system injects a liquefied gas in a state in which the outer end portion of the gas ejecting portion and the outer end portion of the gas injection portion are upward, and the inner end portion of the gas ejecting tube is located inside the inner end portion of the gas injection tube. In this position, the inner end portion of the gas discharge pipe is immersed in the liquefied gas at the time of maximum injection, and is exposed to the liquid surface of the liquefied gas in a standard state, and the gasification gas is discharged, which is a structure for the present invention. It is better. Further, the "inside" when the inner end portion of the gas discharge pipe is located further inward than the inner end portion of the gas injection pipe means that it enters the inner side when viewed from the pipe attachment portion. As a result, although there is a possibility that the front end of the tube is close to the side of the opposite side, in the present invention, it is not a problem to be close to where it is, and it is important to protrude inward.

The can main system is attached to the detachable form of the gun body by inserting operations substantially in the direction of the gun body. That is, the outer end portion of the gas ejecting portion is disposed in front of the insertion direction so that the gas discharge pipe and the gas passage on the gun main body side communicate with each other by the above-described insertion operation. This configuration is also preferable for the present invention.

Since the present invention is configured as described above and functions as described above, it is possible to provide an detachable air tank of a dummy gun which has a simple structure and which does not cause the liquefied gas to leak regardless of the direction in which the gun body faces. Moreover, according to the present invention, it is possible to provide a disassembled type gas storage tank for a dummy gun which is adapted to be mounted in a simulation gun of a manner of attaching the can body to the gun body substantially by inserting operation in the direction of the gun body, even if The gun body is facing downward or upward, and the liquefied gas is also difficult to leak out of the gas passage of the gun body.

The basic structure of the above air gun will be described with reference to Fig. 2. The gas flow path 14 is provided in the gun body 11, and its end reaches a plurality of barrels (gun body) 15. The gas flow path 14 has a gas chamber 17 opened and closed by the valve body 16 in the middle thereof, and has a flow rate adjusting portion 18 adjacent to the side of the elastic portion 15a of the barrel 15 downstream. Further, a portion 11a having the air chamber 17 is provided on the gun body 11 side, and springs 19a and 19b are disposed between the control valve device 25 to be described later.

The valve body 16 is a shaft-shaped member, and the front end portion 16a enters the gas flow path inside the valve hole 17a of the front partition wall of the air chamber 17, and the rear end portion 16b is formed from the shaft hole 17b of the front partition wall of the air chamber 17. It protrudes rearward and is attached to the gun body 11 so as to be movable in the front-rear direction, and is biased by the spring 19b. Further, a projection 16c is provided on the outer circumference of the intermediate portion of the valve body 16, and the projection 16c is stopped by the rear wall of the air chamber and the air chamber 17 is hermetically sealed. On the other hand, the gun body 11 has a trigger 20 which is provided to be rotatable about the shaft 20a, and is configured to open the valve body 16 via the damper 21 and the striker 22 by a firing operation.

The wrought iron 21 is provided to be rotatable around the shaft 21a, and has an engaging target portion 21b that engages with the engaging portion 20b provided in the trigger 20. Further, the striker 22 is attached in such a manner as to be movable in the front-rear direction along the guide shaft 23 provided to the gun body 11, and is biased forward by the spring 23a, and is configured such that the front portion thereof faces the rear end portion 16b of the valve body 16. Pressurize. Trigger 20 During the engagement with the damper 21, the damper 21 is also engaged with a portion 22c of the striker 22 by a portion 21c thereof, so that the striker 22 is placed in the standby position. 2 shows that the trigger 20 is pulled, the engagement of a portion 21c of the resist iron 21 with a portion 22c of the striker 22 is released, and the striker 22 strikes the valve body 16 at the moment. Further, a reset spring is provided on the trigger 20 and the yoke 21.

The flow rate adjustment unit 18 is provided with a control valve device 25. The control valve device 25 is provided with a space 24 leading to the gas flow path 14 and a gas discharge path 26 leading to the space 24 on the upstream side and to the loading portion 15a on the downstream side, and a control valve 27 from the above The space side is slidably inserted into the gas discharge path 26. The gas discharge path 26 is provided in three places in the same manner as the elastic portion 15a, and the control valve 27 is biased in the valve closing direction by the coil spring disposed in each of the internal biasing means 28, thereby being able to abut against the upstream side of the space 24. Part 24a. The portion constituting the flow rate adjusting portion 18 has a gas injection nozzle 18a at the front end portion, and is provided to be movable in the front-rear direction with respect to the gun body 11, forming a part of the bullet loading mechanism.

The control valve 27 has a hollow cylindrical structure in which the barrel side is open and is almost closed on the upstream side, and has a side opening portion 27a and a small opening 27b at the end surface in the intermediate portion of the cylindrical structure as a ventilation means for allowing gas to pass therethrough. Therefore, as the bullet is fired, the control valve 27 enters the gas discharge path 26 until a part of the opening portion 27a becomes a state in which the flow of the gas flowing into the inside of the barrel is restricted, and a small amount of gas can pass through the small opening 27b. On the other hand, the spherical bullet B is supplied from the cartridge 29 attached to the lower portion of the gun body 11 to the loading portion 15a side of the barrel 15.

The tank main body 30 is a device that serves as a gas source for the air gun, and includes a gas injection portion 31 for filling the inside of the liquefied gas, and a gas discharge portion 35 for supplying the vaporized gas accumulated in the gas flow path 14. As shown in detail in FIG. 3, the can body 30 in the embodiment can be attached to the gun body 11 by an insertion operation substantially in the direction of the gun body, and a gas discharge is disposed in front of the insertion direction. The outer end portion of the portion 35 is such that the gas discharge portion 35 communicates with the gas flow path 14 on the gun main body side by the above-described insertion operation.

The gas injection unit 31 has a gas injection pipe 32 that is substantially horizontal in the standard state, and has a gas injection injection valve 33, and the injection valve 33 is housed inside the gas injection pipe 32. The gas injection pipe 32 has a structure of a pipe (i.e., a tubular shape) that constitutes a part of the structure of the can body 30. Further, the can body 30 of the embodiment is formed by plastic molding, and the flat box-shaped can which is closed before the insertion direction and opened later is opened, and the surface is completely closed by the closing plate 34.

The gas ejecting portion 35 has a gas ejecting pipe 36 that is substantially horizontal in the standard state, and has a movable on-off valve 37 that is closed when not attached to the gun body 11 and opened at the time of mounting. The opening and closing valve 37 has a valve housing 37a that is assembled to the outer end portion, a movable valve 37b that is disposed to be movable in the tube axis direction, a spring 37c that biases the movable valve 37b in the valve closing direction, and a vent hole 37d. And the end portion 37e on the connection side, and the gas flow is opened and closed in accordance with the position of the sealing member 37f disposed only in front of the vent hole 37d.

Further, the present invention is characterized in that both the gas discharge pipe 36 and the gas injection pipe 32 are located on the same side surface of the tank main body 30, and the inner end portion 36e of the gas discharge pipe 36 is disposed inside the gas injection pipe 32. The end portion 32e is located further on the inner side. That is, as seen from the mounting portion of each tube, as shown in Fig. 3A, the inner end portion 36e of the gas discharge pipe 36 enters the distance d inwardly from the inner end portion 32e of the gas injection pipe 32.

Inside the mounting chamber 12 to which the can body 30 is attached, an inner wall portion 38 for blocking the can body 30 is provided, and a valve opening nozzle 39 is provided in the inner wall portion to allow gas flow from the gas ejecting portion 35 and the gun main body side. The road 14 is connected (see Figure 3B). The front end 39e of the valve opening nozzle 39 is formed in a reverse tapered shape, and the movable end portion 37e of the opening and closing valve 37 is formed in a tapered shape, and the two are engaged with each other. When the gas discharge portion 35 and the gas flow path 14 on the gun main body side are connected, the movable valve 37b is press-fitted and is in an airtight connection state, and the upper and lower portions of the front surface of the can body 30 enter the blocking portions 38a, 38b. It becomes a steady state (see Figure 4).

According to the invention thus constituted, the following effects can be obtained. First, when the liquefied gas 40 is filled, the front side of the insertion direction of the can body 30 is placed upward (see FIG. 5). In this state, when the nozzle of the gas cylinder is inserted into the gas injection portion 31 to inject the gas, the liquefied gas 40 is filled in the vicinity of the inner end portion 32e of the gas injection pipe 32, and is in a full state. When the tank body 30 in which the liquefied gas 40 is filled to the full state is attached to the gun body 11, the liquid level of the liquefied gas 40 reaches the level of the immersion gas injection pipe 32 in a standard state in which the barrel 15 is substantially horizontal. (See Figure 6).

Therefore, it is clear that in this state, the gas ejecting portion 35 is located at the upper portion of the can body 30, and in this standard state, the gas injecting portion 31 is located lower than the gas ejecting portion 35 of the can body 30. That is, the gas discharge pipe 36 is completely in the region of the gasification gas 41, so that the bullet emission based on the expected pressure is normally performed, and the liquefied gas 40 does not flow out to the gas flow path 14. Therefore, the liquefied gas 45 is not leaked endlessly, and the so-called fuel consumption is also well maintained. Hold as design value. Moreover, the tank main body 30 has the inclined bottom surface 30a which becomes the upper direction toward the front in the front side of the front side of the insertion direction, and the liquid level is the upper part of the tank main body 30 in the standard state at the time of the filling to the intermediate position of the tank main body 30 at the time of injection. The position is thus able to accumulate a larger amount of liquefied gas 40.

Fig. 7 shows the state in which the gun body is facing downward, but the downward state is a state in which the air gun is hung on the shoulder by the shoulder strap. In the downward state, even if the liquefied gas 40 is filled to the full state, the inner end portion 36e of the gas discharge pipe 36 is still positioned at the upper level of the liquid surface. Therefore, only the gasification gas 41 flows into the gas discharge pipe 36, and the phenomenon that the liquefied gas 40 leaks hardly occurs. Therefore, there is no phenomenon in which the liquefied gas 40 is stored in the gas flow path 14.

Further, in the state in which the gun body is horizontal but the gun body 11 is turned upside down, the liquid level is lowered by the amount corresponding to the inclined bottom surface 30a as compared with the standard state when the gun body is horizontal (see Fig. 8). Therefore, neither the gas injection unit 31 nor the gas discharge unit 35 is submerged below the liquid surface of the liquefied gas 40, and therefore the liquefied gas 40 may flow out to the gas flow path 14. However, according to the present invention, there is an opening and closing valve 37 between the tank main body 30 and the gas flow path 14 of the gun body 11, and the amount of liquefied gas that can flow out is extremely limited, so that a large amount of the raw material gas (liquefied gas) does not appear to the gas. The phenomenon in which the flow path 14 flows out can prevent a situation such as deterioration of fuel consumption or abnormal emission of bullets.

As described above, in the apparatus of the present invention, the phenomenon that the liquefied gas leaks into the mechanism inside the gun body hardly occurs, so that the deterioration of the gas fuel consumption can be prevented. In particular, the structure according to the present invention can be suitably applied to an air gun having a structure in which the gas discharge pipe 36 is substantially horizontal, has a gas injection portion 31 on the same side and is connected to the gas. The gas flow path 14 of the discharge portion 35 in the substantially extended direction.
