Detailed Description of the Invention "Field of Industrial Application" The present invention is based on a pressure medium of a toy gun that fires bullets in rapid succession using a pressure medium such as fluorocarbon gas or buoyant gas. This invention relates to a bullet firing method and its firing device.

ス封止弁とから構成されていた。That is, the firing device X for firing bullets 1 using pressure medium G of this toy gun includes a cylinder material 4 having a bone introduction part 3 that fits in a sealed state with the magazine 2, and a fixed part at the tip of the cylinder part 144. A gun barrel 5 attached to the barrel 5, a rubber gasket 6 located inside the barrel 5 and located at the tip of the cylindrical member 4, and a cylindrical member 4.
A gas introduction vibrator 8 is fixedly inserted into the rear end and connected to the gas cylinder 7, and a gas shutoff valve is provided at an appropriate location of the gas introduction vibrator 8 so as to operate in conjunction with a trigger (not shown). It was configured.

、ボン、ボンと言う具合に連続的に発射される。In the above configuration, when the trigger is pulled, the gas shutoff valve 9 is activated and gas flows from the gas cylinder 7 into the cylindrical member 4. When this happens, one of the bullets is first pushed out to the rubber gasket 6. Since the bullet 1 is once received by the rubber gasket 6, it will not be fired immediately unless the internal pressure of the cylinder member 4 rises to the required pressure. When the gas pressure becomes constant, the bullet 1 spawns toward the barrel 5 side, is pushed out by the gas, and is fired. This instantaneous bullet flows into the rubber gasket 6, and when the internal pressure of the cylindrical member 4 becomes constant again, the next bullet is fired. Thereafter, as long as the pressure medium G such as chlorofluorocarbon gas is supplied from the gas cylinder 7 to the cylinder member 4, the bullets 1 are fired continuously in a boom, boom, boom.
しかして、上記構成にあっては次に列挙するような欠点

強い力で発射されるから非常に危険な状態となる。■The rubber gasket 6 plays the role of reliably catching the bullet 1 when it is pushed by the pressure medium G, so if the stopper force of the rubber gasket 6 changes slightly depending on the temperature, the firing speed of the bullet 1 will change accordingly. Different. In other words, the tightening of the rubber gasket 6 (because the release of the bullet 1 is controlled by the hook, for example, in the summer, the rubber gasket 6 becomes soft and can be fired even with very low gas pressure, resulting in a so-called dispersion state, but in the winter When this happens, the rubber gasket 6 will eventually be fired only under considerably high gas pressure, and in this case the bullet will be fired with great force, creating a very dangerous situation.

となっているので、マガジン２そのものの密閉性が問題
となった。すなわら、マガジン２にほんの少しの孔が開
いていてもその孔から圧力媒体Ｇが逃げ、弾を発射でき
ない状態となる。■Since the structure is such that the pressure medium G can freely enter into the magazine 2, the airtightness of the magazine 2 itself has become a problem. In other words, even if the magazine 2 has a small hole, the pressure medium G escapes from the hole, making it impossible to fire bullets.
したがって、マガジンおよびその連結部は完全密閉の構
造のものでなければならない。Therefore, the magazine and its connections must be of completely sealed construction.

。"Means for Solving the Problems of the Invention" In the toy gun of the present invention, the method of firing bullets using a pressure medium is such that when the internal pressure of the outer cylinder member increases, the piston member that locks the weight slides forward and is connected to the magazine. There is a firing preparation process in which the bullet inlet is closed and the bullet is inserted into the packing member, and as soon as this firing preparation process is completed, the weight is disengaged from the piston member and the needle valve seals off the pressure medium. A firing machine that fires a bullet by impact ('I) and a drop in the internal pressure of the outer cylinder member after the firing process is completed to return the piston member to the rear and engage the weight with the piston member. It is characterized by comprising an initial bone introduction step of stopping the bullet and opening the bullet introduction port to move the bullet to the distal end side of the screw member.

T] Close the 13a in a sealed state and insert the bullet 31 into the packing member 30]~
This shows the launch preparation process. That is, in FIG. 2, a pressure medium G such as fluorocarbon gas or propane gas is supplied from a gas cylinder (not shown) to the needle valve 22 side of the engine storage portion 14 of the outer cylinder member 11 through the gas supply hose 18, and as a result, the piston member This shows a state in which internal pressure is applied to the large-diameter F moving part 20d of 20, and the piston member 20 has begun to move somewhat forward in the direction of the arrow. In this case, the piston member 20 is the first spring member 24
The bullet introduction port 13 begins to move against the spring force of
The bullet 31 falling from a is pressed against the packing member 3G at the tip of the piston member 20. Also, the weight 23 is the third
While resisting the spring force of the spring member 28, they move forward together while being engaged with the engaging piece of the piston member and sliding on the cup-shaped portion 22c of the needle valve 22. In other words, the weight 23 is locked to the locking portions 21a of the plurality of engagement pieces, and is pulled by the engagement pieces and moves together. On the other hand, even if the pressure medium G enters the rear side of the engine storage portion 14 of the outer cylinder member 11, the needle valve 22 will not be able to maintain any 83 pressure as in the initial state shown in FIG.
The needle valve chamber 1 (3b is 111) of the inner cylindrical body 1G is biased by the second spring part 27 without receiving any R. In FIG. When the bullet 31 that is pressed by the tip of the bullet 31 moves further forward and enters the packing member 30, the bent portion 21b of the engagement piece 21 bends into the outer circumferential tapered surface 1 formed at the rear of the inner cylinder 16.
It shows the state where it has started sliding contact with 6b. In this case, bullet entrance 1
The next bullet 31a located at position 3a is defined by the piston tip 20a of the piston member 20, but the bullet entrance 13a is not completely closed tightly 111 by the piston tip 20a. The weight 23 is still locked to the engagement piece 21 and located inside the engagement piece, and the needle valve 22 also remains as it is. FIG. 4 does not show a state in which the piston member 20 is further advanced by the pressure medium G, and its tip hits the rear end surface of the packing member 30, indicating that the piston member 20 is ready for firing. In this case, the bullet 31 is completely pushed into the packing member 30, and at the same time, the bullet entrance 13a is sealed by the piston tip 20a, so that even if the pressure medium G is injected from the needle valve 22 side, it will not flow into the magazine containing the bullet. It will not leak.

FIG. 6 shows that the weight 23 that has been sliding vigorously hits the large-diameter rear end 22b of the needle valve 22.
2 shows a state where it starts to move backward. In this case, the weight 23 moves so vigorously that the piston member 20 remains stationary. Figure 7 shows the needle valve 22.
moves backward against the spring force of the second spring member 27 due to the impact of the weight 23, and as a result, the needle valve chamber IGb opens, the pressure medium G is injected to the piston member 20, and the seal member 30
This shows the state in which the bullet 31 inside is fired. At this time, the needle valve 22 is momentarily turned on due to the inertial force of the weight 23. However, an inertial force acts on the weight 23, and a force that tends to move it further backward still acts on the needle valve 22.

As a result, the internal pressure on the rear side of the engine housing part 14 decreases, and the piston member 20 The state is shown in which the state is restored by the spring force of the first spring portion 24. In this case, when the piston member 20 retreats, the inner surface of the rear end of the engagement piece 21 and the outer circumference of the sliding engagement part 23b of the weight 23 try to come into contact with each other, and at the same time, the bullet inlet 13a opens, and the next The bullet 31a is about to fall in front of the piston tip 20a. On the other hand, needle valve 2
2 is still open due to the inertia of the weight 23. FIG. 9 shows a state in which the screw I-2 member 20 has returned to its initial position by the spring force of the first spring member 24. In this state, the inertia of the weight 23 is completely lost, and the needle valve 23 is in the second position.
It moves forward together with the weight 23 due to the repulsive force of the spring member 27, and the 2
1 valve chamber 16b is closed and the weight 23 engages the engagement piece 21.
It is locked again to the locking part 21a.

As long as the pressure medium G continues to be supplied to the engine storage section 14 of No. 1, bullets are fired one after another.
「発明の効果」
以上の説明から明らかなように本発明にあっては、次に
列挙するような効果がある。"Effects of the Invention" As is clear from the above explanation, the present invention has the following effects.
（１）弾を発ｒＪ４する際にピストン先端部で弾導入口
を密閉状態に閉じるので、マガジンおよびその連結部を
精密な密１１１構造とする必要はない。(1) When firing a bullet rJ4, the bullet inlet is closed in a sealed state at the tip of the piston, so there is no need for the magazine and its connecting portion to have a precise closed 111 structure.
したがって、マガジンの形状を自由に設計することがで
きると共にガス圧の漏れにより発射不可能という事態を
同盟することができる。Therefore, the shape of the magazine can be freely designed, and the situation where firing is impossible due to gas pressure leakage can be avoided.
（２）パツキン部材の役割は、弾を軽くソフトタッチで
受【ノ止めあるいは受け入れるだけで十分であるから、
パツキン部材を従来のように全体として硬質のものとす
る必要がない。したがって、パツキン部材が外気温によ
り軟かくまたは硬くなって締め付は力が変化しても、弾
の発射速度に影響を与えることがほとんどない。(2) The role of the packing member is to receive the bullet with a light, soft touch; it is sufficient to stop or accept the bullet.
There is no need to make the packing member hard as a whole as in the conventional case. Therefore, even if the packing member becomes soft or hard depending on the outside temperature and the tightening force changes, the firing speed of the bullet is hardly affected.
（３）ピストン部材で弾をパツキン部材に１発づつ確実
に押し込み、間欠的にボン・ボン・ボンという具合に発
射することかできる。したがって、従来のように散蒔ぎ
状態となることはない。(3) The piston member can reliably push the bullets one by one into the packing member, allowing them to be fired intermittently in a bang-bon-bon manner. Therefore, unlike in the past, the seeds are not scattered.
（４）パツキン部材の形状を自由に変え、圧力媒体Ｇの
圧力を基準に弾の発射速度が定まるようにすることがで
きる。たとえば第１０図で示すようにパツキン部材３０
Ａは、ピストン先端部２０ａが突き当たる後端部３０ａ
を比較的硬くし、一方、弾を受け止める側の先端部３０
ｂは単に弾を軽くソフ１〜なタッチで支持することがで
きるように薄く形成した一実施例であるが、このように
構成しても良い。(4) The shape of the packing member can be freely changed so that the firing speed of the bullet can be determined based on the pressure of the pressure medium G. For example, as shown in FIG.
A is the rear end 30a against which the piston tip 20a abuts.
is made relatively hard, while the tip portion 30 on the side that receives the bullet is made relatively hard.
b is an example in which the bullet is formed thin so that it can simply support the bullet with a light and soft touch, but it may be configured in this way.
