Description

本発明は、銃本体に、圧縮気体を先端ノズル部から噴射するノズルアセンブリーと弾丸を装填する装弾部を有するバレルを具備し、ノズルアセンブリーの後退によって先端ノズル部と上記装弾部との間に弾丸を供給する給弾機構において、装弾数の切替えを行えるようにした装置に関するものである。 The present invention includes a gun body including a barrel assembly having a nozzle assembly for injecting compressed gas from a tip nozzle portion and a bullet loading portion for loading a bullet, and the nozzle assembly is moved backward between the tip nozzle portion and the bullet loading portion. The present invention relates to a device that can change the number of bullets in a bullet feed mechanism that supplies bullets to the tank.

玩具銃或いは模擬銃などと通称される銃では、ＢＢ弾と呼ぶ球形のプラスチック製弾丸を使用する。多くの銃はバレルの装弾部分に１発の弾丸を装填し、従って、１回のコッキング操作で１発の弾丸を発射する操作が繰り返される。これに対して複数個の弾丸を発射する構造を持った銃もあり、本発明の出願人においても、例えば、特開平１１−９４４９５号（特許第３０４５９８４号）を出願している。同号の発明は、複数個の銃身を有する銃に弾丸を装填する装弾装置を開示しており、弾丸は各銃身に通じる装弾室前室から各銃身に１発ずつ自動的に装填される。上記構成の銃では、銃身の個数と同じ数の弾丸を装填し発射することができるが、装填する弾丸の個数を、銃身の個数よりも増加することはできない。 For a gun commonly called a toy gun or a simulated gun, a spherical plastic bullet called a BB bullet is used. Many guns are loaded with a single bullet in the barrel's loading section, and thus the operation of firing a single bullet in a single cocking operation is repeated. On the other hand, there is also a gun having a structure for firing a plurality of bullets, and the applicant of the present invention has applied for, for example, Japanese Patent Application Laid-Open No. 11-94495 (Patent No. 3045984). The invention of the same issue discloses a loading device for loading a bullet into a gun having a plurality of barrels, and the bullets are automatically loaded into each barrel one by one from the chamber front chamber leading to each barrel. The gun having the above-described configuration can load and fire the same number of bullets as the number of barrels, but the number of bullets to be loaded cannot be increased beyond the number of barrels.

複数の弾丸を発射するものには、例えば、複数弾丸発射装置という特開２００４−３２４９６２号の発明がある。その発明は円筒形の弾頭が、６つの装弾室と中央の大きなガス充填筒部とに分離されていて、周囲の各装弾室にそれぞれ４個のプラスチック弾丸が装填されるので、あたかも散弾銃のように、２４発の弾丸を同時に発射することが可能とされている。しかし、弾丸を装填する際は、銃身の先端から弾丸をシ−ル材の凸部に抗して装弾室の底部まで挿入しなければならないと記載されているので、１発ずつ銃身の先端から挿入する必要があるので、大変面倒である。また、同様の構成を有する従来技術では、装弾する場合には弾頭を取り外し、再度複数の弾丸を装弾して（ガスを充填して）から銃身に装着すると記載されている。 For example, Japanese Patent Application Laid-Open No. 2004-324962, which is a multiple bullet firing device, emits a plurality of bullets. In the invention, a cylindrical warhead is divided into six bullet chambers and a large gas-filled cylinder at the center, and four plastic bullets are loaded in each of the surrounding bullet chambers. Thus, it is possible to fire 24 bullets at the same time. However, when loading bullets, it is stated that the bullet must be inserted from the tip of the barrel to the bottom of the bullet chamber against the convex part of the seal material. Since it is necessary to insert, it is very troublesome. Further, in the prior art having the same configuration, it is described that when a bullet is loaded, the warhead is removed and a plurality of bullets are loaded again (filled with gas) and then mounted on the barrel.

このように、上記発明に記載されている装置は、弾丸を装填する操作それ自体が大変面倒なままである。しかも、上記複数弾丸発射装置の発明は１発ずつ挿入する方式を取っており、操作によって弾丸装填数を変更することができるものではなく、また、弾丸装填数の変更に関する技術事項が示唆されているわけでもない。このような状況において、本件の発明者は複数個の弾丸を装填する技術及び複数個の弾丸を装填する弾数を切替えることを可能にする技術の確立を意図し、鋭意研究の結果、本発明を完成したものである。 Thus, the device described in the above invention remains very cumbersome for the operation of loading the bullets themselves. In addition, the invention of the above-mentioned multiple bullet firing device takes a method of inserting one shot at a time, and it is not possible to change the number of bullets loaded by operation, and technical matters relating to the change of the number of bullets loaded are suggested. Not even. In such a situation, the inventor of the present invention intends to establish a technique for loading a plurality of bullets and a technique for switching the number of bullets for loading a plurality of bullets. Is completed.

特開平１１−９４４９５号JP-A-11-94495 特開２００４−３２４９６２号Japanese Patent Application Laid-Open No. 2004-324962

本発明は前記の経緯からなされたもので、その課題は、給弾機構において、バレルに装填する弾丸の数を切替えることが可能な装弾数切替え装置を提供することである。また、本発明の他の課題は、装填する弾丸の装弾数切替え操作を、銃本体に設けた１方向操作方式又は往復操作方式の何れの方式のコッキング部材によっても行えるようにした給弾機構における装弾数切替え装置を提供することである。 The present invention has been made in view of the above circumstances, and an object thereof is to provide a loading number switching device capable of switching the number of bullets loaded in a barrel in a bullet feeding mechanism. Another object of the present invention is to provide a bullet feed mechanism in which the number of bullets to be loaded can be switched by a cocking member of either a one-way operation method or a reciprocation operation method provided on the gun body. It is to provide a loading number switching device.

前記の課題を解決するため、本発明は銃本体に、圧縮気体を先端ノズル部から噴射するノズルアセンブリーと弾丸を装填する装弾部を有するバレルを具備し、ノズルアセンブリーの後退によって先端ノズル部と上記装弾部との間に弾丸を供給する給弾機構において、ノズルアセンブリーの前進後退方向へ移動可能に銃本体に取り付けたコッキング部材と、上記コッキング部材の移動をノズルアセンブリーに伝達し、当該ノズルアセンブリーを後退させるために上記コッキング部材とノズルアセンブリーとの間に設けた作用部材と、上記ノズルアセンブリーを前進方向へ付勢する弾性部材の付勢力に抗して、当該ノズルアセンブリーを後退させるためにコッキング部材と作用部材に設けた係合手段と、上記係合手段における係合を有効にするか無効にするかを選択することによって、コッキング部材の移動をノズルアセンブリーに伝達するか伝達しないかを選択するために、作用部材を切替える装弾数切替え部材を具備して構成するという手段を講じたものである。 In order to solve the above-described problems, the present invention includes a gun body including a barrel having a nozzle assembly for injecting compressed gas from a tip nozzle portion and a bullet loading portion for loading a bullet, and the tip nozzle portion is retracted by retreating the nozzle assembly. And a bullet feeding mechanism for supplying a bullet between the bullet loading part and the cocking member attached to the gun body so as to be movable in the forward and backward direction of the nozzle assembly, and the movement of the cocking member is transmitted to the nozzle assembly, The nozzle assembly against the biasing force of an action member provided between the cocking member and the nozzle assembly for moving the nozzle assembly backward and an elastic member biasing the nozzle assembly in the forward direction. Engagement means provided on the cocking member and the action member for retreating the lever, and whether or not the engagement in the engagement means is valid In order to select whether or not the movement of the cocking member is transmitted to the nozzle assembly by selecting whether or not to be effective, a means is provided to include a loading number switching member that switches the working member. Is.

ノズルアセンブリーの後退によって先端ノズル部と上記装弾部との間に弾丸を供給するために空所を設ける給弾機構は本発明の装置の前提になっているが、この方式自体は公知であり、例えば、前述の特許文献１のものも同様である。本発明の装置はそのような給弾機構における先端ノズル部の後退動作を繰り返すことによって、装弾数を切替えるものであるといえる。 A bullet feed mechanism that provides a space for supplying a bullet between the tip nozzle portion and the bullet loading portion by retreating the nozzle assembly is a premise of the device of the present invention, but this method itself is known. For example, the thing of the above-mentioned patent document 1 is also the same. It can be said that the device of the present invention switches the number of bullets by repeating the backward movement of the tip nozzle portion in such a bullet feeding mechanism.

そのため、本発明の装置は、装弾数切替え操作を行う操作部材として前進後退方向へ移動可能に銃本体に取り付けたコッキング部材と、このコッキング部材の移動をノズルアセンブリーに伝達して後退させるために上記コッキング部材とノズルアセンブリーとの間に設けた作用部材と、上記ノズルアセンブリーを前進方向へ付勢する弾性部材の付勢力に抗して後退させるためにコッキング部材と作用部材に設けた係合手段と、この係合手段における係合を有効にするか無効にするかを選択することによって、コッキング部材の移動をノズルアセンブリーに伝達するか伝達しないかを選択するために、作用部材を切替える装弾数切替え部材を具備している。 For this reason, the apparatus of the present invention is provided with a cocking member attached to the gun body so as to be movable in the forward and backward direction as an operation member for performing the operation for switching the number of bullets, An action member provided between the cocking member and the nozzle assembly, and an engagement member provided on the cocking member and the action member to retract the nozzle assembly against an urging force of an elastic member for urging the nozzle assembly in the forward direction. In order to select whether or not to transmit the movement of the cocking member to the nozzle assembly by selecting the coupling means and whether to enable or disable the engagement in the engagement means, It is equipped with an ammunition number switching member for switching.

故に、本発明はコッキング部材を前進後退方向へ移動操作させる際に作用部材を切替えることで、ノズルアセンブリーを後退させる回数、即ち、装填する弾丸の個数を制御することができる。そのコッキング部材の操作は、作用部材を介してノズルアセンブリーに伝達される。よって、作用部材の伝達作用が行なわれる回数を制御することで、上記ノズルアセンブリーを後退させる回数が変えられる。コッキング部材と作用部材は係合手段によって係合可能になっており、故にこの係合の有効無効を選択することが、コッキング部材の移動をノズルアセンブリーに伝達するか伝達しないかの選択、即ち、装填回数の制御であり、装弾数を切替えることになる。 Therefore, according to the present invention, the number of times the nozzle assembly is retracted, that is, the number of bullets to be loaded can be controlled by switching the action member when the cocking member is moved in the forward and backward direction. The operation of the cocking member is transmitted to the nozzle assembly via the action member. Therefore, the number of times the nozzle assembly is retracted can be changed by controlling the number of times that the action member is transmitted. The cocking member and the working member are engageable by the engaging means, so that selecting whether the engagement is valid or not means whether the movement of the cocking member is transmitted or not transmitted to the nozzle assembly, that is, This is control of the number of times of loading, and the number of loadings is switched.

本発明の装置では、上記コッキング部材の１方向操作又は往復方向操作のいずれの方式も選択することができる。１方向操作とは、例えば、１回のコッキング部材の後退操作によってノズルアセンブリーを複数回後退させる操作である。この場合、コッキング部材の前進時は装弾数切替えに関与せず、原位置に戻すだけである。１方向操作を取る装置において、コッキング部材は移動方向に沿って間隔を設けて配置した、例えば、２箇所の係合部を有し、上記２箇所の係合部の回数だけノズルアセンブリーを後退可能に構成され、作用部材は、上記２箇所の係合部とともに係合手段を構成する係合相手として、１箇所目の係合部と係合する部分１を有し、また、１箇所目の係合部との係合を解除するために、ノズルアセンブリーの後方に配置された解除部と接触する部分２を有し、また、１箇所目の係合部との係合を強制的に解除する装弾数切替え部材の操作によって接触し、１箇所目の係合部との係合を解除する部分３を有して構成され、さらに、２箇所目の係合部と係合する第２の部分１をノズルアセンブリーに設けて構成される。 In the apparatus of the present invention, either one-way operation or reciprocation operation of the cocking member can be selected. The one-way operation is, for example, an operation of retracting the nozzle assembly a plurality of times by one retraction operation of the cocking member. In this case, when the cocking member moves forward, it is not involved in the change in the number of bullets, but is simply returned to the original position. In a device that performs a one-way operation, the cocking member is disposed at intervals along the moving direction. For example, the cocking member has two engaging portions and retracts the nozzle assembly by the number of times of the two engaging portions. The action member has a portion 1 that engages with the first engagement portion as an engagement partner constituting the engagement means together with the two engagement portions, and the first position. In order to release the engagement with the engaging portion of the nozzle assembly, it has a portion 2 that comes into contact with the releasing portion disposed at the rear of the nozzle assembly, and forcibly engages with the first engaging portion. And a portion 3 that comes into contact with the operation of the number-of-mounts switching member to be released and releases the engagement with the first engaging portion, and further engages with the second engaging portion. Two parts 1 are provided in the nozzle assembly.

他方、往復方向操作はコッキング部材を後退、前進させる操作であり、後退、前進の操作により装弾数切替えを行なう。往復方向操作を取る装置において、コッキング部材は、移動方向の中間に設けた１箇所の係合部を有し、上記１箇所の係合部の往復移動によってノズルアセンブリーを後退させるものとして構成され、作用部材はノズル本体及びコッキング部材に対して前後方向へ移動可能に、かつ、それ自体が回転可能に銃本体に取り付けられており、さらに、上記１箇所の係合部と係合して回転を生じさせる部分１を有し、また、上記回転によってノズルアセンブリー側のラックと噛み合、移動を生じさせる歯から成る部分２を有し、また、コッキング部材の後退に伴って、コッキング部材と作用部材に設けた係合手段によりノズルアセンブリーが後退し、さらに、付勢手段により前進した状態から、コッキング部材の前進に伴うノズルアセンブリーの後退を行わせるか否かを選択する部分３を有して構成される。 On the other hand, the reciprocating operation is an operation for moving the cocking member backward and forward, and the number of bullets is switched by the backward and forward operations. In the apparatus that performs the reciprocal operation, the cocking member has one engaging portion provided in the middle of the moving direction, and is configured to retreat the nozzle assembly by the reciprocating movement of the one engaging portion. The action member is attached to the gun body so as to be movable in the front-rear direction with respect to the nozzle body and the cocking member, and is also rotatably attached to the gun body. And a portion 2 composed of teeth that mesh and move with the rack on the nozzle assembly side by the rotation, and when the cocking member is retracted, The nozzle assembly is retracted by the engaging means provided on the action member and further moved from the state advanced by the urging means to the nozzle assembly following the advancement of the cocking member. Configured with a portion 3 for selecting whether to perform.

上記の部分１、部分２、部分３は１方向操作方式の装置と、往復方向操作方式の装置のどちらにも必要な構成要素である。しかしこれらの構成要素は構成及び作用等の具体的内容において、全て一致するというものではなく、１方向操作方式の装置と、往復方向操作方式という方式の相違により内容にも相違があらわれる。また、各々の部分１ないし部分３は各１箇所とは限らず、複数箇所の場合もあり得る。本発明はそれらを包含するものである。 The above-described parts 1, 2 and 3 are components necessary for both the one-way operation type device and the reciprocating direction operation type device. However, these components do not all coincide with each other in specific contents such as configuration and operation, and the contents differ depending on the difference between the one-way operation method apparatus and the reciprocal operation method method. Further, each of the portions 1 to 3 is not limited to one location but may be a plurality of locations. The present invention includes them.

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、給弾機構において、コッキング部材の操作によってバレルに装填する装弾数を切替えることが可能になり、発射可能な弾数を多くも少なくも選択することができるという効果を奏する。また、本発明によれば、装填する弾丸の装弾数切替え操作を、１方向操作方式又は往復操作方式の何れの方式のコッキング部材によっても行えるようにした、給弾機構における装弾数切替え装置を提供することができるので、実施に当たり自由度が大きいという効果がある。 Since the present invention is configured and operates as described above, in the bullet feeding mechanism, it is possible to switch the number of bullets loaded in the barrel by operating the cocking member, and the number of bullets that can be fired is small or large. There is an effect that can also be selected. In addition, according to the present invention, there is provided a device for switching the number of bullets in a bullet feed mechanism, wherein the number of bullets to be loaded can be switched by a cocking member of either a one-way operation method or a reciprocating operation method. Therefore, there is an effect that the degree of freedom in implementation is large.

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は本発明に係る給弾機構における装弾数切替え装置の一例を示すものであり、内部機構を示す全体的な断面図と共に、切替え機構を特に示すために要部の外観図を併記している。１１は銃本体、１２は圧縮ガスのガス源、１３はガス流路であり、圧縮ガスを先端ノズル部から噴射するノズルアセンブリー１４を経て、弾丸Ｂを装填する装弾部１５ａを有するバレル１５へ噴射する構成を有している。 Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments.

The front end 16a enters the gas flow path in the main body, and the rear end 16b is rearward from a part of the gun main body 11. It is mounted so that it can move in the front-rear direction. Further, a protrusion 16c is provided on the outer periphery of the valve body 16 near the rear side of the intermediate part, and the protrusion 16c seals the air chamber 17 in an airtight manner by contacting a seat 16d at the rear of the air chamber. And is biased by the spring 16e in that direction. The cylindrical portion located behind the protrusion 16c is provided with a gas passage 16f that passes inside and outside, and when the valve body 16 moves forward, the gas flow passes through the gas passage 16f and flows into the inside of the valve body. It is the structure made to flow in. A mechanism for hermetically sealing is provided between the front end portion 16a and the rear end portion 16b of the valve body 16 so as to be movable.

図示の例は、３個のバレル１５を束ねた３銃身型のものであり、それに合わせて、ノズルアセンブリー１４も、３箇所の装弾部１５ａと、それぞれの装弾部１５ａの上流に接続した３個の摺動部１４ａと、それら全てに通じる１箇所の上記調整部１４ｂと、各摺動部１４ａにそれぞれ組み込まれた制御弁１４ｃと、制御弁１４ｃをガス流の上流方向へ加圧するバネ１４ｄを有している。ノズルアセンブリー１４は、また、３箇所の先端ノズル部１４ｅを有しており、これらの先端ノズル部１４ｅは前進、後退によって３箇所の各装弾部１５ａに出入可能に設けられ、後退時に弾丸Ｂを供給するため空所２２を設けるように構成されている。制御弁１４ｃは、弾丸発射操作に伴って生じる圧縮ガス流の圧力差により閉弁方向へ押されるが、常にガス流通を維持する小開口を有しており、発射操作に伴う弾丸Ｂの移動開始後原位置に復帰する構成となっている。 The illustrated example is of a three-barrel type in which three barrels 15 are bundled. In accordance with this, the nozzle assembly 14 is also connected to the three loaded portions 15a and upstream of the respective loaded portions 15a. Each of the sliding portions 14a, one adjusting portion 14b communicating with all of them, a control valve 14c incorporated in each sliding portion 14a, and a spring 14d for pressurizing the control valve 14c in the upstream direction of the gas flow. have.

Further, engaging means 38 are provided between the cocking member 31 and the action member 34 and between the cocking member 31 and the nozzle assembly 14, respectively. The action member 34 has a portion 1 (35-1) as an engagement partner constituting the engagement means 38 together with the first engagement portion 32, and is engaged with the first engagement portion 32. In order to release, the portion 2 (35-2) that contacts the release portion 36 disposed at the rear of the nozzle assembly is provided, and the engagement with the first engagement portion 32 is forced. It has a portion 3 (35-3) that comes into contact with the operation of the loading number switching member 37 to be released and releases the engagement with the first engaging portion 32.

上記例１の装弾数切替え装置３０において、付勢手段のバネ１１ｂは、後端部にてガス銃本体１１の気室１７を有する部分１１ａに支持され、前端部にてノズルアセンブリー１４を押圧している。作用部材３４は、上記ノズルアセンブリー１４の側面に軸３４ａによって回転可能に軸支され、部分１（３５−１）が、前後に長く形成されているコッキング部材３１の上面を摺動可能に設けられている。解除部３６は、気室１７を有する部分１１ａの側面に、前下方に向けて設けられた斜面から成り、部分２（３５−２）の後退時にそれと接触可能である。さらに、弾数切替え部材３７は、バレル１５の後端部にあって、それと一体的に設けられ、後下方に向けた斜面にて部分３（３５−３）に当接可能に設けられている。 In the bullet number switching device 30 of Example 1 above, the spring 11b of the biasing means is supported at the rear end portion by the portion 11a having the air chamber 17 of the gas gun body 11, and presses the nozzle assembly 14 at the front end portion. doing. The action member 34 is rotatably supported on the side surface of the nozzle assembly 14 by a shaft 34a, and the portion 1 (35-1) is slidably provided on the upper surface of the cocking member 31 formed long in the front and rear direction. It has been. The release portion 36 is composed of an inclined surface provided on the side surface of the portion 11a having the air chamber 17 toward the front lower side, and can come into contact with the portion 2 (35-2) when it is retracted. Further, the bullet number switching member 37 is provided at the rear end portion of the barrel 15 and is provided integrally therewith, and is provided so as to be able to contact the portion 3 (35-3) with a slope directed rearward and downward. .

例１の装弾数切替え装置３０の作用について説明する。まず、図１では弾丸Ｂがカートリッジ２４の内部のバネによって加圧され、その状態から給弾路２４ａを上昇して装弾部１５ａに向かい、そこに入り込んでいる先端ノズル部１４ｅに突き当たっている。この状態において、図４に示すようにコッキング部材３１を後方へ移動させると、それによって作用部材３４の部分１（３５−１）が１箇所目の係合部３２と係合し、作用部材３４に後方への移動力が伝わり、その結果、ノズルアセンブリー１４が後退した状態となる。ノズルアセンブリー１４の後退によって、先端ノズル部１４ｅと上記装弾部１５ａとの間に空所２２（装弾部前室２５）が形成される。かくして、給弾機構２３を経て給弾路２４ａから弾丸Ｂが空所２２に供給される。最初の３発の弾丸Ｂの供給の後、コッキング部材３１を後方へ移動させることで、作用部材３４が図５において反時計方向へ回転し、それによって、部分１（３５−１）が１箇所目の係合部３２との係合から外れるので、ノズルアセンブリー１４が付勢手段のバネ１１ｂによって前方へ押され（図５中段）、弾丸Ｂが装弾部１５ａに装填されるとともに、装弾部１５ａとの間の空所２２が閉じる。この段階で、３個のバレル１５の装弾部１５ａに各１発ずつ計３発の弾丸Ｂが装填されたことになり、ここで、弾丸Ｂの供給は一旦断たれることになる。 The effect | action of the loading number switching apparatus 30 of Example 1 is demonstrated. First, in FIG. 1, the bullet B is pressurized by a spring inside the cartridge 24, and from this state, the bullet B is lifted up toward the bullet loading portion 15a and hits the tip nozzle portion 14e entering there. In this state, when the cocking member 31 is moved rearward as shown in FIG. 4, the portion 1 (35-1) of the action member 34 is thereby engaged with the first engaging portion 32, and the action member 34. As a result, the nozzle assembly 14 is retracted. As the nozzle assembly 14 moves backward, a space 22 (a front chamber 25) is formed between the tip nozzle portion 14e and the mounting portion 15a. Thus, the bullet B is supplied to the empty space 22 from the bullet feed path 24 a via the bullet feed mechanism 23. After supplying the first three bullets B, the action member 34 is rotated counterclockwise in FIG. 5 by moving the cocking member 31 rearward, so that the portion 1 (35-1) is one place. Since it disengages from the engagement portion 32 of the eye, the nozzle assembly 14 is pushed forward by the spring 11b of the urging means (the middle stage in FIG. 5), and the bullet B is loaded into the loading portion 15a. The space 22 between 15a is closed. At this stage, the bullets B of the three barrels 15 are loaded with a total of three bullets B, one each, and the supply of the bullets B is once cut off.

コッキング部材３１をさらに後方へ移動させると、作用部材３４は一旦時計方向へ回転し、それに伴い、部分１（３５−１）はコッキング部材３１の上面付近を移動し、ノズルアセンブリー１４の前部に設けられている２箇所目の係合部３３が溝部３１ａを移動してその前端係合部３１ｂに当接し、ノズルアセンブリー１４に後方への移動力が伝えられる（図６上段）。その結果ノズルアセンブリー１４が後退し、再び先端ノズル部１４ｅと上記装弾部１５ａとの間の空所２２（装弾部前室２５）に、給弾機構２３を経て給弾路２４ａから、図外のバネによって加圧された弾丸Ｂが供給される（図６中段並びに下段）。その後、コッキング部材３１を前方へ移動させると、ノズルアセンブリー１４は図６中段の状態から付勢手段のバネ１１ｂによって前方へ押され（図７上段）、装弾部１５ａとの間の空所２２が閉じる。この結果、３個のバレル１５の各装弾部１５ａに各２発ずつ計６発の弾丸Ｂが装填されたことになる（図７下段）。 When the cocking member 31 is further moved rearward, the action member 34 once rotates clockwise, and accordingly, the portion 1 (35-1) moves near the upper surface of the cocking member 31, and the front portion of the nozzle assembly 14 is moved. The second engaging portion 33 provided on the second portion moves in the groove portion 31a and comes into contact with the front end engaging portion 31b, so that a backward moving force is transmitted to the nozzle assembly 14 (upper stage in FIG. 6). As a result, the nozzle assembly 14 retreats, and again enters the space 22 (the front chamber 25 of the impacting portion) between the tip nozzle portion 14e and the impacting portion 15a from the bullet feeding path 24a via the bullet feeding mechanism 23, not shown. The bullet B pressed by the spring is supplied (middle stage and lower stage in FIG. 6). Thereafter, when the cocking member 31 is moved forward, the nozzle assembly 14 is pushed forward from the state in the middle of FIG. 6 by the spring 11b of the urging means (upper stage in FIG. 7), and the space 22 between the loading portion 15a and the space 22 is formed. Closes. As a result, a total of six bullets B are loaded in each of the bullet loading portions 15a of the three barrels 15 (two in each row) (lower row in FIG. 7).

次に、例１の装弾数切替え装置３０において、３発のみ装填する場合の作用について説明する。３発のみ装填の場合には、図８に示すようにバレル１５の後端部にある装弾数切替え部材３７を操作し、後下方に向けた斜面に当接する部分３（３５−３）を押し下げるようにする。これは、作用部材３４を予め反時計方向へ回転させておき、コッキング部材３１を後退させる１回目の操作をしても、部分１（３５−１）が１箇所目の係合部３２と係合しないキャンセル状態にするものである（図９）。コッキング部材３１をさらに後方へ移動させると、上記部分１（３５−１）は１箇所目の係合部３２と係合しない状態にあり、ノズルアセンブリー１４の前部に設けられている２箇所目の係合部３３が、コッキング部材３１の溝部３１ａを移動してその前端３１ｂに当接するので、ノズルアセンブリー１４に後方への移動力が伝えられる（図１０上段）。その結果、ノズルアセンブリー１４が後退し、先端ノズル部１４ｅと上記装弾部１５ａとの間の空所２２（装弾部前室２５）に、給弾機構２３を経て給弾路２４ａから、図外のバネによって加圧された弾丸Ｂが供給される（図１０下段）。その後、コッキング部材３１を前方へ移動させると、ノズルアセンブリー１４が付勢手段のバネ１１ｂによって前方へ押され（図１１上段）、装弾部１５ａとの間の空所２２が閉じる。これにより、３個のバレル１５の装弾部１５ａには３発のみ弾丸Ｂが装填されたことになる（図１１下段）。
Next, an operation in the case where only three shots are loaded in the loaded number switching device 30 of Example 1 will be described. In the case of loading only three shots, as shown in FIG. 8, the number-of-loads switching member 37 at the rear end of the barrel 15 is operated to push down the portion 3 (35-3) that contacts the inclined surface directed rearward and downward. Like that. Even if the action member 34 is rotated in the counterclockwise direction in advance and the first operation for retracting the cocking member 31 is performed, the portion 1 (35-1) is engaged with the first engaging portion 32. The cancel state is set so as not to match (FIG. 9). When the cocking member 31 is further moved rearward, the portion 1 (35-1) is not engaged with the first engaging portion 32, and two portions provided at the front portion of the nozzle assembly 14 are provided. Since the engaging portion 33 of the eye moves in the groove portion 31a of the cocking member 31 and comes into contact with the front end 31b, a backward moving force is transmitted to the nozzle assembly 14 (upper stage in FIG. 10). As a result, the nozzle assembly 14 moves backward, and enters the void 22 (the front chamber front chamber 25) between the tip nozzle portion 14e and the above-mentioned bullet loading portion 15a from the bullet feed path 24a via the bullet feed mechanism 23, not shown. The bullet B pressed by the spring is supplied (lower stage in FIG. 10). Thereafter, when the cocking member 31 is moved forward, the nozzle assembly 14 is pushed forward by the spring 11b of the urging means (the upper stage in FIG. 11), and the space 22 between the bullet loading portion 15a is closed. As a result, only three bullets B are loaded in the loading portions 15a of the three barrels 15 (lower row in FIG. 11).

さらに、往復方向操作方式に係る例２の装弾数切替え装置４０について図１２以下を参照して説明する。例２の装弾数切替え装置４０において、コッキング部材４１は前後に長く形成され、ノズルアセンブリー１４の前進後退方向へ移動可能に銃本体１１に取り付けられている（図１２）。例２の装弾数切替え装置４０において、コッキング部材４１は、移動方向の中間に設けた１箇所の係合部４２を有し、コッキング部材４１の往復移動によって、この１箇所の係合部４２を、ノズルアセンブリー１４を２度後退させるように構成する。なお、ノズルアセンブリー１４に、それを原位置復帰のために前進させる付勢手段として複数個のバネ１１ｂが配置されていること及び給弾機構２３等の構成についても、例１と同様である。 Furthermore, the number-of-loads switching device 40 of Example 2 according to the reciprocating direction operation method will be described with reference to FIG. In the bullet number switching device 40 of Example 2, the cocking member 41 is formed long in the front-rear direction, and is attached to the gun body 11 so as to be movable in the forward and backward direction of the nozzle assembly 14 (FIG. 12). In the loading number switching device 40 of Example 2, the cocking member 41 has one engaging portion 42 provided in the middle of the moving direction, and the one engaging portion 42 is moved by the reciprocating movement of the cocking member 41. The nozzle assembly 14 is configured to retract twice. The nozzle assembly 14 is provided with a plurality of springs 11b as urging means for moving it forward to return to the original position, and the configuration of the bullet feeding mechanism 23 and the like is the same as in Example 1. .

作用部材４３はノズルアセンブリー１４及びコッキング部材４１に対して前後方向へ移動可能に、かつ、それ自体が回転可能に銃本体１１の側に取り付けられている。さらに、上記１箇所の係合部４２と係合して回転を生じさせる部分１（４５−１）を有し、また、上記回転によってノズルアセンブリー側のラック４４と噛み合い移動を生じさせる歯４７から成る部分２（４５−２）を有し、また、コッキング部材４１の後退に伴って、コッキング部材４１と作用部材４３に設けた上記部分１（４５−１）との係合によりノズルアセンブリー１４が後退し、さらに、付勢手段のバネ１１ｂにより前進した状態から、ノズルアセンブリー１４を後退位置へ戻して、コッキング部材４１の前進に伴うノズルアセンブリー１４の後退を行わせるか否かを選択する部分３（４５−３）を有している。 The action member 43 is attached to the side of the gun body 11 so as to be movable in the front-rear direction with respect to the nozzle assembly 14 and the cocking member 41 and so as to be rotatable. Furthermore, it has a portion 1 (45-1) that engages with the one engaging portion 42 to cause rotation, and a tooth 47 that meshes with the rack 44 on the nozzle assembly side by the rotation and causes movement. The nozzle assembly is formed by the engagement of the cocking member 41 with the portion 1 (45-1) provided on the action member 43 as the cocking member 41 is retracted. Whether the nozzle assembly 14 is moved backward and further moved forward by the spring 11b of the urging means, the nozzle assembly 14 is returned to the retracted position, and the nozzle assembly 14 is moved backward as the cocking member 41 moves forward. It has the part 3 (45-3) to select.

例２の装弾数切替え装置４０において、上記係合部４２はコッキング部材４１の上面のほぼ中央部に突出し、前後に斜面４２ａ、４２ｂを有する台形状に形成されている。作用部材４３は扇型の形状を有し、その要に当たる部分４３ａにて可動部材４６に回転可能に軸支され、扇型の円弧の前端部に部分１（４５−１）が、また、後半部分に歯４７が設けられている。上記可動部材４６は、銃本体側に前後方向へ移動可能に設けられ、かつ、バネ４６ａによって後方へ付勢され、ストッパー４６ｂにて停止している（図１２Ｂ）。係合手段５０は、銃本体側に軸４８ａによって軸支した装弾数切替え部材４８の係合爪４８ｂと、係合爪４８ｂと係合可能に上記可動部材４６の後端部に設けられた、鉤型の係合相手４９とから成っている。 In the bullet number switching device 40 of Example 2, the engaging portion 42 is formed in a trapezoidal shape having a slope 42a, 42b on the front and rear sides, projecting substantially at the center of the top surface of the cocking member 41. The action member 43 has a fan-shaped shape, and is pivotally supported by the movable member 46 at a portion 43a corresponding to the main portion 43, and a portion 1 (45-1) is formed at the front end portion of the fan-shaped arc. The part is provided with teeth 47. The movable member 46 is provided on the gun body side so as to be movable in the front-rear direction, is urged rearward by a spring 46a, and is stopped by a stopper 46b (FIG. 12B). The engagement means 50 is provided at the rear end portion of the movable member 46 so as to be engageable with the engagement claw 48b of the bullet number switching member 48 pivotally supported on the gun body side by the shaft 48a, and the engagement claw 48b. It consists of a hook-shaped engagement partner 49.

例２の装弾数切替え装置４０の作用について説明する。図１２では、図１と同様に弾丸Ｂがカートリッジ２４の内部のバネによって加圧され、その状態から給弾路２４ａを上昇して装弾部１５ａに向かい、そこに入り込んでいる先端ノズル部１４ｅに突き当たっているものとする。この状態において、コッキング部材４１を後方へ移動させると、その係合部４２の斜面４２ａに部分１（４５−１）が係合して押し上げられることにより、作用部材４３が図中反時計方向に回転し（図１３Ａ）、部分２（４５−２）において歯４７がラック４４と噛み合い、ノズルアセンブリー１４をバネ１１ｂに抗して後退させる。その結果、先端ノズル部１４ｅと上記装弾部１５ａとの間の空所２２（装弾部前室２５）が形成されるので、給弾機構２３を経て給弾路２４ａから弾丸Ｂが空所２２に供給される。さらにコッキング部材４１を後方へ移動させると作用部材４３が図中時計方向に回転し（図１３Ｂ）、部分１（４５−１）が係合部４２の斜面４２ｂに係合し、ノズルアセンブリー１４がバネ１１ｂの付勢下に前進し弾丸Ｂが装弾部１５ａに装填されるとともに、装弾部１５ａとの間の空所２２が閉じる。この段階で、３個のバレル１５の装弾部１５ａに各１発ずつ計３発の弾丸Ｂが装填される。 The operation of the bullet number switching device 40 of Example 2 will be described. In FIG. 12, the bullet B is pressurized by the spring inside the cartridge 24 as in FIG. 1, and then rises from the bullet feed path 24a toward the bullet loading portion 15a and enters the tip nozzle portion 14e entering there. Assume that you are hitting. In this state, when the cocking member 41 is moved rearward, the action member 43 is moved counterclockwise in the figure by engaging and pushing up the portion 1 (45-1) to the inclined surface 42a of the engaging portion 42. Rotates (FIG. 13A) and teeth 47 engage with rack 44 in portion 2 (45-2), causing nozzle assembly 14 to retract against spring 11b. As a result, a void 22 (a bullet chamber front chamber 25) is formed between the tip nozzle portion 14e and the bullet loading portion 15a, so that the bullet B enters the void 22 from the bullet feed path 24a via the bullet feed mechanism 23. Supplied. When the cocking member 41 is further moved rearward, the action member 43 rotates in the clockwise direction in the drawing (FIG. 13B), the portion 1 (45-1) engages with the inclined surface 42b of the engaging portion 42, and the nozzle assembly 14 Moves forward under the bias of the spring 11b and the bullet B is loaded into the loading portion 15a, and the space 22 between the loading portion 15a is closed. At this stage, a total of three bullets B are loaded into the loading portions 15a of the three barrels 15 one by one.

次に、コッキング部材４１を最も後退した位置から前方へ移動させる操作を行うと、今度は往路とは逆に、係合部４２の斜面４２ｂに部分１（４５−１）が係合して押し上げられ、作用部材４３が図中反時計方向に回転し（図１３Ｃ）、その歯４７がラック４４と噛み合い、ノズルアセンブリー１４をバネ１１ｂに抗して後退させる。よって、先端ノズル部１４ｅと上記装弾部１５ａとの間の空所２２（装弾部前室２５）が形成され、給弾機構２３を経て給弾路２４ａから弾丸Ｂが空所２２に供給される。さらにコッキング部材４１を前方へ移動させると作用部材４３が図中時計方向に回転し（図１３Ｄ）、部分１（４５−１）が係合部４２の斜面４２ｂに係合し、ノズルアセンブリー１４がバネ１１ｂの付勢下に前進し弾丸Ｂが装弾部１５ａに装填されるとともに、装弾部１５ａとの間の空所２２が閉じる。これによって、３個のバレル１５の装弾部１５ａに各２発ずつ計６発の弾丸Ｂが装填されたことになる。 Next, when the operation of moving the cocking member 41 forward from the most retracted position is performed, the portion 1 (45-1) is engaged with the inclined surface 42b of the engaging portion 42 and pushed up, this time, contrary to the outward path. Then, the action member 43 rotates counterclockwise in the figure (FIG. 13C), and its teeth 47 engage with the rack 44, causing the nozzle assembly 14 to retract against the spring 11b. Therefore, a void 22 (a front chamber 25 for loading portion) is formed between the tip nozzle portion 14e and the bullet loading portion 15a, and the bullet B is supplied to the void 22 from the bullet feeding path 24a via the bullet feeding mechanism 23. . When the cocking member 41 is further moved forward, the action member 43 rotates in the clockwise direction in the drawing (FIG. 13D), the portion 1 (45-1) engages with the inclined surface 42b of the engaging portion 42, and the nozzle assembly 14 Moves forward under the bias of the spring 11b and the bullet B is loaded into the loading portion 15a, and the space 22 between the loading portion 15a is closed. As a result, a total of six bullets B are loaded into each of the bullet loading portions 15a of the three barrels 15, two shots each.

例２の装弾数切替え装置４０において、３発のみ装填する場合には、図１４に示すように、係合手段５０を操作して装弾数切替え部材４８の係合爪４８ｂと鉤型の係合相手４９との係合を外しておく（図１４Ａ）。この状態では、作用部材４３はバネ４６ａによって後方へ付勢され、ストッパー４６ｂにて停止しているだけである（図１２Ｂ）。しかし、コッキング部材４１を後方へ移動させると、その係合部４２の斜面４２ａに部分１（４５−１）が係合して押し上げられ、作用部材４３が図中反時計方向に回転し（図１４Ａ）、部分２（４５−２）において歯４７がラック４４と噛み合い、ノズルアセンブリー１４をバネ１１ｂに抗して後退させる。その結果、先端ノズル部１４ｅと上記装弾部１５ａとの間の空所２２（装弾部前室２５）が形成されるので、給弾機構２３を経て給弾路２４ａから弾丸Ｂが空所２２に供給される。さらにコッキング部材４１を後方へ移動させると作用部材４３が図中時計方向に回転し（図１４Ｂ）、部分１（４５−１）が係合部４２の斜面４２ｂに係合し、ノズルアセンブリー１４がバネ１１ｂの付勢下に前進し弾丸Ｂが装弾部１５ａに装填されるとともに、装弾部１５ａとの間の空所２２が閉じ、従って、３個のバレル１５の装弾部１５ａに各１発ずつ計３発の弾丸Ｂが装填される。 When only three shots are loaded in the bullet number switching device 40 of Example 2, as shown in FIG. 14, the engagement means 50 is operated to engage the engagement claws 48b of the bullet number switching member 48 with the saddle type engagement. The engagement with the counterpart 49 is released (FIG. 14A). In this state, the action member 43 is urged rearward by the spring 46a and is only stopped by the stopper 46b (FIG. 12B). However, when the cocking member 41 is moved rearward, the portion 1 (45-1) is engaged with the inclined surface 42a of the engaging portion 42 and pushed up, and the action member 43 rotates counterclockwise in the figure (FIG. 14A), in part 2 (45-2), the teeth 47 engage with the rack 44, and the nozzle assembly 14 is retracted against the spring 11b. As a result, a void 22 (a bullet chamber front chamber 25) is formed between the tip nozzle portion 14e and the bullet loading portion 15a, so that the bullet B enters the void 22 from the bullet feed path 24a via the bullet feed mechanism 23. Supplied. When the cocking member 41 is further moved rearward, the action member 43 rotates in the clockwise direction in the drawing (FIG. 14B), the portion 1 (45-1) engages with the inclined surface 42b of the engaging portion 42, and the nozzle assembly 14 Advances under the urging force of the spring 11b and the bullet B is loaded into the loading portion 15a, and the space 22 between the loading portion 15a is closed, so that one shot is placed in each of the loading portions 15a of the three barrels 15. A total of three bullets B are loaded.

続けて、コッキング部材４１を最も後退した位置から前方へ移動させる操作を行うと、今度は往路とは逆に、係合部４２の斜面４２ｂに部分１（４５−１）に接触するが、同部分１（４５−１）は斜面４２ｂに押し上げられるものの、ノズルアセンブリー１４に作用しているバネ１１ｂの付勢力に抗することができず（図１４Ｃ）、ほとんど後退しないため先端ノズル部１４ｅと上記装弾部１５ａとの間に空所２２が形成されない。さらにコッキング部材４１を前方へ移動させると、作用部材４３は元の位置に戻るが、結局往復移動の後半では給弾がされないため、３発の弾丸Ｂが装填されるに留まるものである。 Subsequently, when an operation for moving the cocking member 41 forward from the most retracted position is performed, this time, contrary to the outward path, the inclined surface 42b of the engaging portion 42 contacts the portion 1 (45-1). Although the portion 1 (45-1) is pushed up by the inclined surface 42b, it cannot resist the urging force of the spring 11b acting on the nozzle assembly 14 (FIG. 14C), and hardly recedes. A space 22 is not formed between the mounting portion 15a. When the cocking member 41 is further moved forward, the action member 43 returns to the original position. However, since the bullet is not supplied in the latter half of the reciprocating movement, only three bullets B are loaded.

このように本発明の装置は構成されているので、装弾数の切替えを容易かつ確実に行うことができる。例１及び例２において６発の装弾を終えた後、コッキング部材４１を後退させた場合には、さらに３発の弾丸Ｂが装填され、前進により６発が装填されるから、バレル数の倍数分だけ装填する弾丸数を増加させることも可能である。また、上記の各例は３個のバレル１５を束ねた３銃身型のものであるが、これを４銃身以上の型の或いは単銃身型銃に適用することも容易になし得る。上述したとおり、本発明はガス銃を対象としたものであるが、使用されるガスは圧縮された気体であり、従って、本発明は、圧縮空気を圧力源として構成された銃についても適用可能である。また、ガス源の構造についても、図１に示したのはガス銃本体１１に作り付け式に設けたものであり、図１２に示したのはガス銃本体４１に着脱式に設けたものであるが、上記のとおり本発明はそのどちらのタイプにも適用することができる。 Since the apparatus of the present invention is configured in this way, the number of bullets can be switched easily and reliably. In Example 1 and Example 2, when the cocking member 41 is retracted after finishing six shots, three more bullets B are loaded, and six shots are loaded by forward movement. It is also possible to increase the number of bullets loaded. In addition, each of the above examples is a three-barrel type in which three barrels 15 are bundled, but this can be easily applied to a four-barrel or more type or single-barrel type gun. As described above, the present invention is intended for a gas gun, but the gas used is a compressed gas. Therefore, the present invention can also be applied to a gun configured using compressed air as a pressure source. It is. As for the structure of the gas source, what is shown in FIG. 1 is a built-in type in the gas gun body 11, and FIG. 12 is a detachable type in the gas gun body 41. However, as described above, the present invention can be applied to both types.
