[Solution] In an imitation gun wherein a bullet is arranged in an airstream injection channel and is fired by means of a compressed airstream, an airstream leakage part (20) that leaks the compressed airstream is formed in the injection channel or in a section that leads into the injection channel as a means for restricting the firing power of the bullet (15) in accordance with the mass of the bullet.

Description

模擬銃における威力抑制装置Power control device for simulated gun
　本発明は気流の噴射径路上に弾丸を配置し、圧縮気流により発射する模擬銃において、発射威力を抑制する装置に関するものである。 The present invention relates to a device that suppresses the launching power of a simulated gun in which a bullet is disposed on the jetting path of the airflow and is fired by a compressed airflow.
　エアガン又はガスガンなどの模擬銃については、銃砲刀剣類所持等取締法第１条の２等において発射された弾丸の運動エネルギーについて規定されており、それによれば６ｍｍの弾丸を使用した場合、特定された測定点におけるエネルギーが３．５Ｊ／ｃｍ２よりも大きくなると準空気銃の扱いとなると理解される。従って、上記の規定値を超えるガスガンは製造されていない。しかし、幾つかの条件が重なった場合には、一時的に規定値を超えることも考えられる。例えば、真夏の高温下での使用は上記の問題を生じさせる可能性がある。 For simulated guns such as air guns and gas guns, the kinetic energy of bullets fired in Article 1 of Article 1 of the Law on Possession of Guns, Swords, etc. is stipulated. According to this, it is specified when a 6 mm bullet is used. It is understood that if the energy at the measurement point is greater than 3.5 J / cm 2, it is handled as a quasi-air gun. Therefore, no gas gun exceeding the specified value is manufactured. However, when several conditions overlap, it may be considered that the specified value is temporarily exceeded. For example, use at high temperatures in midsummer can cause the above problems.
　温度条件とは別に、メーカーの意図していない弾丸を用いたときには、それも問題になり得る。この種の模擬銃では上記のとおり直径６ｍｍの弾丸が使用され、ＢＢ弾と呼ばれている。そのＢＢ弾として、各メーカーから販売されているのはプラスチック成形品であるが、ボールベアリングの直径６ｍｍの金属球を弾丸に流用した例も報告されている。このため、通常使用されるプラスチック製ＢＢ弾以外の重量弾の使用、真夏の高温下での使用及び通常使用される１３４ａなどのガス以外のハイパワーなパワーソース（ＣＯ２）の使用等の条件が組み合わされると、予測不能な弾速の上昇現象が発生し得る。 Apart from temperature conditions, it can also be a problem when using bullets not intended by the manufacturer. In this type of simulated gun, a bullet having a diameter of 6 mm is used as described above and is called a BB bullet. As the BB bullet, a plastic molded product is sold by each manufacturer, but an example in which a metal ball having a ball bearing diameter of 6 mm is used for a bullet has also been reported. For this reason, conditions such as the use of heavy bullets other than plastic BB bullets that are normally used, use under high temperatures in midsummer, and use of high-power power sources (CO 2 ) other than gas such as 134a that are normally used When combined, an unpredictable increase in bullet speed may occur.
　このように、プラスチック製ＢＢ弾よりも質量の大きい、金属製ボールベアリングなどが弾丸として使用されることは、メーカー各社にとって見過ごしにできない事態である。何らかの対策を講じなければ、期せずして違法行為が見逃される恐れもあり、当業界にとっても好ましいことではないからである。しかしながら、予想していなかった事態であるので金属製弾丸を区別したり、排除したりする技術も知られていない。 As described above, the use of a metal ball bearing or the like having a mass larger than that of a plastic BB bullet as a bullet is a situation that cannot be overlooked by manufacturers. If no measures are taken, there is a risk that illegal activities will be missed unexpectedly, which is not preferable for the industry. However, since this is an unexpected situation, there is no known technique for distinguishing or eliminating metal bullets.
　先行技術を調査すると、特開２００９－１４３２７号のエアガンに関する発明が見出された。同号の発明は、ガス放出流路内に設けられ、ガス蓄圧室からインナーバレルへ放出される圧縮ガスの圧力および流量が一定以上の値になると自動的にガス放出流路内からインナーバレルへの流路を自動バルブが、狭めつつ閉鎖することによりガス蓄圧室からインナーバレルへ放出される圧縮ガスの圧力および流量を調整するという構成を有する。しかしながら、自動バルブという部材の追加による複雑化の問題もあり、また、弾丸が発射される前に自動バルブがガス放出口を閉じないとはいえないなど、実用化には疑問が残る。 When the prior art was investigated, an invention related to an air gun disclosed in Japanese Patent Application Laid-Open No. 2009-14327 was found. The invention of the same number is provided in the gas discharge flow path, and automatically moves from the gas discharge flow path to the inner barrel when the pressure and flow rate of the compressed gas discharged from the gas accumulator chamber to the inner barrel reach a certain value or more. The automatic valve has a configuration in which the pressure and flow rate of the compressed gas discharged from the gas accumulator chamber to the inner barrel are adjusted by closing the flow path of the automatic valve while narrowing. However, there is also a problem of complication due to the addition of a member called an automatic valve, and there is a question in practical use that it cannot be said that the automatic valve does not close the gas discharge port before the bullet is fired.
特開２００９－１４３２７号JP 2009-14327 A
　本発明は前記の点に鑑みなされたもので、その課題は、プラスチック製のＢＢ弾よりも質量の大きい弾丸が使用された場合でも、発射された弾丸の運動エネルギーが規定値を超えないようにするもので、特に、最も簡便な模擬銃における威力抑制装置を提供することである。また、本発明の他の課題は、プラスチック製のＢＢ弾とそれよりも質量の大きい弾丸を混合使用した場合において、ＢＢ弾による運動エネルギーをほとんど低下させずに済む模擬銃における威力抑制装置を提供することである。 The present invention has been made in view of the above points, and the problem is that even when a bullet having a mass larger than that of a plastic BB bullet is used, the kinetic energy of the fired bullet does not exceed a specified value. In particular, it is an object of the present invention to provide a power control device for the simplest simulated gun. Another object of the present invention is to provide a power suppression device for a simulated gun that hardly reduces the kinetic energy of a BB bullet when a plastic BB bullet and a bullet with a mass larger than that are mixed. It is to be.
　前記の課題を解決するため、本発明は気流の噴射径路上に弾丸を配置し、圧縮気流により発射する模擬銃において、弾丸の発射威力を弾丸の質量に応じて抑制する手段として、圧縮気流を漏洩させる気流漏洩部を、上記噴射径路又は噴射径路に通じる部分に形成するという手段を講じたものである。本発明の適用が可能な模擬銃は、圧縮気流を使用する模擬銃であり、空気を使用するエアガンと空気以外の気体を使用するいわゆるガスガンが主なものである。従って、本発明において、圧縮気流は、圧縮空気と、圧縮された空気以外の気体の流れを総称するものである。 In order to solve the above-described problems, the present invention provides a simulated gun in which a bullet is disposed on an airflow injection path and fired by a compressed airflow. Means is provided in which the airflow leakage portion to be leaked is formed in the above-described injection path or a portion communicating with the injection path. The simulation gun to which the present invention can be applied is a simulation gun using a compressed air flow, and mainly an air gun using air and a so-called gas gun using a gas other than air. Therefore, in the present invention, the compressed air flow is a general term for compressed air and a flow of gas other than compressed air.
　その模擬銃の構成において、本発明の装置は、圧縮気流を漏洩させる気流漏洩部を有することを特徴とする。圧縮気流は、ＢＢ弾にも金属製の弾丸にも同等の加圧力で噴射されるが、弾丸に作用する加速度は、作用力に比例し、弾丸の質量に反比例するというニュートンの運動方程式に従う。 In the construction of the simulated gun, the apparatus of the present invention is characterized by having an airflow leakage portion that leaks a compressed airflow. The compressed air current is injected into the BB bullet and the metal bullet with the same applied pressure, but the acceleration acting on the bullet follows the Newton equation of motion that is proportional to the acting force and inversely proportional to the mass of the bullet.
　すなわち、より軽量な（質量の小さい）弾丸はより小さい運動エネルギーで移動を開始するのに対し、より重量物（質量の大きい）の弾丸はより大きい運動エネルギーでなければ移動を開始することができない。つまり、より軽量であるＢＢ弾は気流の漏洩時間が短くして発射されるのに対して、より重量物である金属製の弾丸が発射されるまでには気流の漏洩時間も長くかかる。一方、１発の弾丸発射に使われる圧縮気流の量は一定であり、漏洩分だけ威力が抑制されることになる。 That is, lighter (smaller mass) bullets start moving with less kinetic energy, whereas heavier (higher mass) bullets can only start moving with higher kinetic energy. . That is, while the lighter BB bullet is fired with a short airflow leakage time, it takes a long airflow leakage time before a heavy metal bullet is fired. On the other hand, the amount of compressed airflow used to fire one bullet is constant, and the power is suppressed by the amount of leakage.
　本発明の装置として、気流漏洩部が、圧縮気流が通過し得る噴射径路又は噴射径路に、直接通じる部分に形成された、常時開口の小孔又は隙間によって構成されている形態は、好ましいものである。常時開口の気流漏洩部であれば、構成がより単純化され、また、気流を漏洩させない方式と比較して弾丸発射までの時間差もより少なくて済む。 As an apparatus of the present invention, a mode in which the airflow leakage portion is configured by a small hole or a gap that is always open and formed in a portion that directly communicates with the injection path or the injection path through which the compressed airflow can pass is preferable. is there. If the airflow leaking portion is always open, the configuration is further simplified, and the time difference until the bullet is fired is smaller than the method in which the airflow is not leaked.
　気流漏洩部は、弾丸の配置されている噴射径路上の位置よりも上流に位置しており、かつまた、圧縮気流が通過し得る常時開口の流路であるという構成は、本発明にとって一つの好ましい形態である。しかし、気流漏洩部は、弾丸の配置されている噴射径路上の位置の上流から下流にかけての部分に形成されるという形態も取り得る。 The configuration in which the airflow leakage portion is located upstream from the position on the injection path where the bullets are arranged and is a constantly open flow path through which the compressed airflow can pass is one aspect of the present invention. This is a preferred form. However, the airflow leakage portion may be formed in a portion from upstream to downstream of the position on the injection path where the bullet is arranged.
　本発明は以上のように構成され、かつ、作用するものであるから、プラスチック製のＢＢ弾との比較において、より質量の大きい金属製などの弾丸が使用された場合でも、発射された弾丸の運動エネルギーが規定値を超えないように威力を抑制することが、常時開口の流路という最も簡便な構成によって達成できるという効果を奏する。また、本発明によれば、プラスチック製のＢＢ弾とそれよりも質量の大きい金属製などの弾丸を混合使用した場合において、ＢＢ弾による運動エネルギーをほとんど低下させずに済む模擬銃における威力抑制装置を提供することができる。 Since the present invention is configured and operates as described above, even when a bullet such as a metal having a larger mass is used in comparison with a plastic BB bullet, Suppressing the power so that the kinetic energy does not exceed the specified value has an effect that it can be achieved by the simplest configuration of a constantly open flow path. Further, according to the present invention, when a plastic BB bullet and a metal bullet having a mass larger than that of the plastic BB bullet are mixed and used, the power suppression device for the simulated gun that hardly reduces the kinetic energy due to the BB bullet. Can be provided.
　以下図示の実施形態を参照して本発明をより詳細に説明する。図１は本発明に係る威力抑制装置を適用する模擬銃１０を示しており、模擬銃１０としては、圧縮空気を使用するエアガンと空気以外の気体を使用するガスガンが主なものである。図１ないし図６に示す例はガスガンの場合である。 Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows a simulated gun 10 to which a power suppression device according to the present invention is applied. The simulated gun 10 is mainly an air gun using compressed air and a gas gun using a gas other than air. The example shown in FIGS. 1 to 6 is a gas gun.
　ガスガンは圧縮気流として圧縮ガスを使用するもので、その概略について説明するが、具体的な構成は公知のものと同様で良い。圧縮ガスはガス源１１に充填されており、トリガー１２の操作に伴ってガス放出を制御する放出弁１３から噴射径路１４に放出され、バレル１６の後部の装弾部に配置されている弾丸１５に噴射される。放出された圧縮ガスが流れる噴射径路１４にはスライドシリンダー１７が装備されており、マガジン１９から供給される弾丸１５を、前後方向へのスライドにより装弾部に配置するように構成されている。 The gas gun uses a compressed gas as a compressed air flow, and its outline will be described, but the specific configuration may be the same as a known one. The compressed gas is filled in the gas source 11, and is discharged from the discharge valve 13 that controls the gas discharge to the injection path 14 in accordance with the operation of the trigger 12, and is applied to the bullet 15 disposed in the rear loading portion of the barrel 16. Be injected. A slide cylinder 17 is provided in the injection path 14 through which the compressed gas discharged flows, and the bullet 15 supplied from the magazine 19 is configured to be placed in the loading portion by sliding in the front-rear direction.
　本発明に係る威力抑制装置と直接関係するものではないが、スライドシリンダー１７の内部に設けられている弁装置１８について説明しておく。弁装置１８は弾丸発射の後にバレル側への圧縮気流の流出を一時的に閉塞し、シリンダー内部に留めて後方に位置するピストン２７、及びそれと一体のスライドを後退させ、模擬的なブローバックを起させるものである。弁装置１８は内部に配置された付勢手段１８ａのコイルばねによってガス流の上流方向に付勢され、スライドにより側面の開口部１８ｂの面積が変化するように構成されている。 Although not directly related to the power control device according to the present invention, the valve device 18 provided inside the slide cylinder 17 will be described. The valve device 18 temporarily blocks the flow of the compressed air flow to the barrel side after the bullet is fired, and keeps the piston 27 located behind the cylinder 27 and the slide integrated therewith to move back the simulated blowback. It is something that will happen. The valve device 18 is urged in the upstream direction of the gas flow by a coil spring of an urging means 18a disposed therein, and the area of the side opening 18b is changed by sliding.
　本発明に係る威力抑制装置において、気流漏洩部２０は、弾丸１５の配置されている噴射径路上の位置よりも上流に位置しており、かつまた、圧縮気流が通過し得る常時開口の流路として構成されている。上記弾丸１５の配置されている噴射径路上の位置とは、バレル１６の後部の装弾部である。このようなガスガンに適用される威力抑制装置の実施形態について、図２ないし図６を参照して説明する。なお、各図中の矢印は、各例における圧縮気流の流れ方向を概略的に示している。 In the power suppression device according to the present invention, the airflow leaking portion 20 is located upstream of the position on the injection path where the bullet 15 is disposed, and is a constantly open flow path through which the compressed airflow can pass. It is configured as. The position on the injection path where the bullet 15 is disposed is a bullet loading portion at the rear of the barrel 16. An embodiment of a power suppression device applied to such a gas gun will be described with reference to FIGS. In addition, the arrow in each figure has shown roughly the flow direction of the compressed airflow in each example.
　図２に示すガスガン用威力抑制装置の例１において、気流漏洩部２０は、圧縮気流が通過し得る噴射径路１４の一部であるバレル後端部に開けられた、常時開口の流路である小孔２１として構成されている。実施形態の各例では装弾部にホップアップ装置２６が設けられており、このため小孔２１はバレル１６とホップアップ装置の筒材の両方を貫通する構造として、噴射径路外に圧縮気流を漏洩させるものである。 In the first example of the power suppression device for gas gun shown in FIG. 2, the airflow leakage portion 20 is a constantly open flow passage opened at the rear end of the barrel that is a part of the injection path 14 through which the compressed airflow can pass. The small hole 21 is configured. In each example of the embodiment, the hop-up device 26 is provided in the bullet loading portion. Therefore, the small hole 21 has a structure that penetrates both the barrel 16 and the tubular material of the hop-up device, and leaks the compressed airflow outside the injection path. It is something to be made.
　図３に示すガスガン用威力抑制装置の例２では、気流漏洩部２０は、圧縮気流が通過し得る噴射径路１４の一部であるバレル１６の口径を弾丸１５の直径よりも一回り大径に設けることで、隙間２２が弾丸１５の周囲に出来るように構成されている。隙間２２であるから常時開口の流路であると言える。例２の場合、装弾部に設けたホップアップ装置２６は、やや長めに形成されている。例２の隙間２２は弾丸１５の周囲にて圧縮気流を漏洩させる。 In the example 2 of the power suppressor for a gas gun shown in FIG. 3, the airflow leakage portion 20 makes the diameter of the barrel 16, which is a part of the injection path 14 through which the compressed airflow can pass, slightly larger than the diameter of the bullet 15. By providing, the gap 22 can be formed around the bullet 15. Since it is the gap 22, it can be said that the channel is always open. In the case of Example 2, the hop-up device 26 provided in the loading section is formed slightly longer. The gap 22 in Example 2 leaks the compressed airflow around the bullet 15.
　図４に示すガスガン用威力抑制装置の例３において、気流漏洩部２０は、圧縮気流が通過し得る噴射径路１４の一部としてスライドシリンダー１７のノズル１７ａに開けられた、常時開口の流路である小孔２３として構成されている。例３の場合には装弾部よりも後方の位置に、スライドシリンダーノズル１７ａを貫通する構造として小孔２３が設けられており、噴射径路外に圧縮気流を漏洩させるものとして構造的に最も簡単である。 In the third example of the power suppressor for gas gun shown in FIG. 4, the airflow leaking portion 20 is a constantly open flow path opened in the nozzle 17a of the slide cylinder 17 as a part of the injection path 14 through which the compressed airflow can pass. It is configured as a small hole 23. In the case of Example 3, a small hole 23 is provided as a structure penetrating the slide cylinder nozzle 17a at a position rearward of the bullet loading portion, and it is the simplest structurally for leaking a compressed airflow outside the injection path. is there.
　図５に示すガスガン用威力抑制装置の例４では、気流漏洩部２０は、圧縮気流が通過し得る噴射径路１４の一部としてスライドシリンダー１７の本体部分に設けられた、常時開口の流路である小孔２４として構成されている。例４の場合には装弾部よりも後方、かつ、ピストン２７よりも前方の位置に、スライドシリンダーノズル１７ａを貫通する構造として小孔２４が設けられている。よって、これも噴射径路外に圧縮気流を漏洩させるものとして構造的に簡単である。 In the fourth example of the power suppression device for gas gun shown in FIG. 5, the airflow leakage portion 20 is a constantly open flow passage provided in the main body portion of the slide cylinder 17 as a part of the injection path 14 through which the compressed airflow can pass. It is configured as a small hole 24. In the case of Example 4, a small hole 24 is provided as a structure penetrating the slide cylinder nozzle 17 a at a position behind the loading portion and ahead of the piston 27. Therefore, this is also structurally simple as a compressed air flow is leaked outside the injection path.
　図６に示すガスガン用威力抑制装置の例５では、気流漏洩部２０は、圧縮気流が通過し得る噴射径路１４の一部であるバレル後端部とスライドシリンダーノズル１７ａとの間に設けた、隙間２５として構成されている。これも隙間２５であるから常時開口の気流漏洩部といえる。例５の隙間２５は、スライドシリンダー１７の前進位置の調整によって設定することができる。 In the example 5 of the gas gun power suppression device shown in FIG. 6, the airflow leakage portion 20 is provided between the barrel rear end portion that is a part of the injection path 14 through which the compressed airflow can pass and the slide cylinder nozzle 17a. The gap 25 is configured. Since this is also the gap 25, it can be said that the airflow leakage portion is always open. The gap 25 in Example 5 can be set by adjusting the advance position of the slide cylinder 17.
　さらに本発明に係る威力抑制装置として、圧縮空気を使用するエアガンに適用した例について説明する。図７はエアガンの基本的構成を示しており、ガスガンのガス源の代わりとして空気を圧縮するピストンシリンダー装置３０を装備している。このピストンシリンダー装置３０はピストン２８とシリンダー２９とから成り、ピストン２８の作動により圧縮された空気を圧縮気流とするもので、ピストン２８のコッキング方式は手動又は電動を選択することができる。 Further, an example in which the present invention is applied to an air gun using compressed air will be described as a power suppression device according to the present invention. FIG. 7 shows a basic configuration of an air gun, and a piston cylinder device 30 for compressing air is provided instead of a gas source of the gas gun. The piston / cylinder device 30 includes a piston 28 and a cylinder 29, and uses compressed air as compressed air by the operation of the piston 28. The cocking method of the piston 28 can be selected manually or electrically.
　上記のエアガンに本発明に係る威力抑制装置を適用する場合においても、共通するバレル１６、ホップアップ装置２６などについては符号を援用し、詳細な説明を省略する。以下、さらにエアガンに適用される威力抑制装置の実施形態について、図８ないし図１３を参照して説明する。 Even when the power suppression device according to the present invention is applied to the above air gun, the common barrel 16, the hop-up device 26 and the like are referred to by reference numerals, and detailed description thereof is omitted. Hereinafter, an embodiment of a power control device applied to an air gun will be described with reference to FIGS. 8 to 13.
　図８に示すエアガン用威力抑制装置の例１において、気流漏洩部２０は、圧縮気流が通過し得る噴射径路１４の一部であるバレル後端部に開けられた、常時開口の流路である小孔３１として構成されている。これはガスガン用威力抑制装置の例１の場合と同様にホップアップ装置２６が設けられており、このため小孔３１はバレル１６とホップアップ装置の筒材の両方を貫通する構造として、噴射径路外に圧縮気流を漏洩させるものである。なお、本例１はガスガン用の例１（図２）と対応する。 In Example 1 of the air gun power suppression device shown in FIG. 8, the airflow leakage portion 20 is a constantly open flow passage opened at the rear end of the barrel that is a part of the injection path 14 through which the compressed airflow can pass. It is configured as a small hole 31. This is provided with the hop-up device 26 in the same manner as in the case of the gas gun power suppression device example 1. Therefore, the small hole 31 has a structure that penetrates both the barrel 16 and the cylinder of the hop-up device, and the injection path. The compressed airflow is leaked outside. In addition, this example 1 respond | corresponds to the example 1 (FIG. 2) for gas guns.
　図９に示すエアガン用威力抑制装置の例２では、気流漏洩部２０は、圧縮気流が通過し得る噴射径路１４の一部であるバレル１６の口径を弾丸１５の直径よりも一回り大径に設けることで、隙間３２として構成されている。隙間３２であるからこれも常時開口の流路であると言える。例２の場合、装弾部に設けたホップアップ装置２６は、やや長めに形成されることになる。例２の隙間３２は弾丸１５の周囲にて圧縮気流を漏洩させる。なお、本例２はガスガン用の例２（図３）と対応する。 In the example 2 of the air gun power suppression device shown in FIG. 9, the airflow leakage portion 20 makes the diameter of the barrel 16, which is a part of the injection path 14 through which the compressed airflow can pass, slightly larger than the diameter of the bullet 15. By providing, it is configured as a gap 32. Since it is the gap 32, it can be said that this is also a constantly open channel. In the case of Example 2, the hop-up device 26 provided in the loading section is formed slightly longer. The gap 32 in Example 2 leaks the compressed airflow around the bullet 15. The second example corresponds to the second example (FIG. 3) for the gas gun.
　図１０に示すエアガン用威力抑制装置の例３において、気流漏洩部２０は、圧縮気流が通過し得る噴射径路１４の一部としてエアガン用シリンダー２９のノズル２９ａに開けられた、常時開口の流路である小孔３３として構成されている。例３の場合には装弾部よりも後方の位置に、スライドシリンダーノズル２９ａを貫通する構造として小孔３３が設ければ良いので、噴射径路外に圧縮気流を漏洩させるものとして構造的に最も簡単である。なお、本例３はガスガン用の例３（図４）と対応する。 In the third example of the air gun power suppression device shown in FIG. 10, the airflow leakage portion 20 is a flow path that is always open and is opened in the nozzle 29a of the airgun cylinder 29 as a part of the injection path 14 through which the compressed airflow can pass. It is comprised as the small hole 33 which is. In the case of Example 3, since it is only necessary to provide a small hole 33 as a structure penetrating the slide cylinder nozzle 29a at a position behind the loading portion, it is the simplest structurally as one that leaks a compressed airflow outside the injection path. It is. In addition, this example 3 respond | corresponds to the example 3 (FIG. 4) for gas guns.
　図１１に示すエアガン用威力抑制装置の例４では、気流漏洩部２０は、圧縮気流が通過し得る噴射径路１４の一部としてスライドシリンダー２９の本体部分に設けられた、常時開口の流路である小孔３４として構成されている。例４の場合には装弾部よりも後方、かつ、ピストン２８の前進限界よりも前方の位置に、スライドシリンダーノズル２９ａを貫通する構造として小孔３４が設けられている。よって、これも噴射径路外に圧縮気流を漏洩させるものとして構造的に簡単である。なお、本例４はガスガン用の例４（図５）と対応する。 In Example 4 of the air gun power suppression device shown in FIG. 11, the airflow leakage portion 20 is a constantly open flow path provided in the main body portion of the slide cylinder 29 as a part of the injection path 14 through which the compressed airflow can pass. It is configured as a small hole 34. In the case of Example 4, a small hole 34 is provided as a structure penetrating the slide cylinder nozzle 29 a at a position behind the loading portion and ahead of the advance limit of the piston 28. Therefore, this is also structurally simple as a compressed air flow is leaked outside the injection path. In addition, this example 4 respond | corresponds to the example 4 (FIG. 5) for gas guns.
　図１２に示すガスガン用威力抑制装置の例５では、気流漏洩部２０は、圧縮気流が通過し得る噴射径路１４の一部であるバレル後端部とスライドシリンダーノズル１７ａとの間に設けた、隙間３５として構成されている。これも隙間２５であるから常時開口の気流漏洩部といえる。なお、例５の隙間３５は、スライドシリンダー１７の前進位置の調整によって設定することができる。本例５はガスガン用の例５（図６）と対応する。 In the example 5 of the power suppressor for a gas gun shown in FIG. 12, the airflow leakage portion 20 is provided between the barrel rear end portion that is a part of the injection path 14 through which the compressed airflow can pass and the slide cylinder nozzle 17a. The gap 35 is configured. Since this is also the gap 25, it can be said that the airflow leakage portion is always open. Note that the gap 35 in Example 5 can be set by adjusting the advance position of the slide cylinder 17. The present example 5 corresponds to the gas gun example 5 (FIG. 6).
　図１３に示すエアガン用威力抑制装置の例６では、気流漏洩部２０は、圧縮気流が通過し得る噴射径路１４に通じる部分である、エアガン用シリンダー２９の内周面よりもピストン２８の外周の直径を一回り小径に設けることで、隙間３６として構成されている。隙間３６であるからこれも常時開口の流路であるといえる。例６の場合は、空気の圧縮能力を意図して低下させることになる。 In Example 6 of the air gun power suppression device shown in FIG. 13, the airflow leakage portion 20 is located on the outer periphery of the piston 28 rather than the inner peripheral surface of the airgun cylinder 29, which is a portion communicating with the injection path 14 through which the compressed airflow can pass. A gap 36 is formed by providing the diameter slightly smaller. Since it is the gap 36, it can be said that this is also a constantly open channel. In the case of Example 6, the compression capability of air is intentionally reduced.
　図１４に示すエアガン用威力抑制装置の例７では、気流漏洩部２０は、圧縮気流が通過し得る噴射径路１４に通じる部分である、エアガン用シリンダー２９の内周面を摺動するピストン２８にこれを貫通する小孔３７を設けることで構成されている。小孔３７であるから、これも常時開口の流路である。例７の場合も、空気の圧縮能力を意図して低下させる点、例５と同様である。 In the example 7 of the air gun power control device shown in FIG. 14, the airflow leakage portion 20 is formed on the piston 28 that slides on the inner peripheral surface of the airgun cylinder 29, which is a portion communicating with the injection path 14 through which the compressed airflow can pass. It is configured by providing a small hole 37 penetrating therethrough. Since this is the small hole 37, this is also a constantly open channel. The case of Example 7 is the same as Example 5 in that the air compression capacity is reduced intentionally.
　このように構成されている本発明によれば、プラスチック製のＢＢ弾との比較上、より質量の大きい金属製などの弾丸が使用された場合でも、発射された弾丸の運動エネルギーが規定値を超えないように威力を抑制することができるので、想定外の威力を発揮して安全性を害するような事態を起こす危険がない。しかも、プラスチック製のＢＢ弾とそれよりも質量の大きい金属製などの弾丸を混合使用しても、ＢＢ弾の威力をほとんど低下させずに済むので、従来の威力とほぼ同等の威力の模擬銃として扱うことができ、ユーザーに不満を抱かせる恐れもない。 According to the present invention configured as described above, even when a bullet such as a metal having a larger mass is used in comparison with a plastic BB bullet, the kinetic energy of the fired bullet has a specified value. Since the power can be suppressed so as not to exceed, there is no risk of causing an unexpected power to cause a situation that would harm safety. Moreover, even if a plastic BB bullet and a metal bullet with a larger mass are used in combination, the power of the BB bullet can be hardly reduced, so that the simulated gun has almost the same power as the conventional one. And there is no fear of frustrating the user.
