消火器本体１上には、第１アーム部材１１と第２アーム部材１２とが並列に配置される。第１アーム部材１１は、消火薬剤２を放出する容器弁としてのバルブボディ４の開放／閉鎖を制御するための起動レバーとして働き、第２アーム部材１２は固定レバーとして働く。ここでは、第１、第２アーム部材１１，１２は、難燃性あるいは不燃性材料、例えば鉄やアルミニウム等の金属や金属合金から構成された溝形（チャンネル）であり、開口部が対抗して配置されている。 The first arm member 11 and the second arm member 12 are arranged in parallel on the fire extinguisher main body 1. The first arm member 11 acts as a start lever for controlling the opening / closing of the valve body 4 as a container valve for discharging the fire extinguishing agent 2, and the second arm member 12 acts as a fixing lever. Here, the first and second arm members 11 and 12 have a groove shape (channel) made of a flame-retardant or non-flammable material, for example, a metal such as iron or aluminum or a metal alloy, and the openings oppose each other. Are arranged.

これら第１、第２アーム部材１１，１２における対応する中間点は、連結部材１３，１４によって離隔して連結されている。連結部材１３，１４は、各中間点を支点として第１、第２アーム部材１１，１２の一端側と他端側を交互に開閉可能に保持する。 The corresponding intermediate points of the first and second arm members 11 and 12 are separated and connected by the connecting members 13 and 14. The connecting members 13 and 14 alternately hold one end side and the other end side of the first and second arm members 11 and 12 so as to be openable and closable with each intermediate point as a fulcrum.

図３に示すように、連結部材１３，１４は、第１、第２アーム部材１１，１２を挟んで配置され、互いの一端がボルト２１−１とナット２１−２により第１アーム部材１１の中間点に軸支され、他端がボルト２２−１，２３−１とナット（図示しない）により第２アーム部材１２における対応する中間点に固定される。 As shown in FIG. 3, the connecting members 13 and 14 are arranged so as to sandwich the first and second arm members 11 and 12, and one end of each of the first arm member 11 is formed by a bolt 21-1 and a nut 21-2. It is pivotally supported at an intermediate point, and the other end is fixed to the corresponding intermediate point in the second arm member 12 by bolts 22-1, 23-1 and a nut (not shown).

尚、ここで中間点とは、第１、第２アーム部材１１，１２における両端から１／２の距離、あるいは重心位置の意味ではなく、一端側と他端側の間の意味である。この中間点は、第１、第２アーム部材１１，１２の長さや、バルブボディ４を開閉するために必要な第１、第２アーム部材１１，１２の距離（連結部材１３，１４の長さ）などに応じて適宜設定する。 Here, the intermediate point does not mean the distance of 1/2 from both ends of the first and second arm members 11 and 12, or the position of the center of gravity, but means between one end side and the other end side. This intermediate point is the length of the first and second arm members 11 and 12 and the distance between the first and second arm members 11 and 12 required for opening and closing the valve body 4 (the lengths of the connecting members 13 and 14). ) Etc., and set as appropriate.

上記第１、第２アーム部材１１，１２の一端側には、熱感知部材１５が設けられている。熱感知部材１５は、第１、第２アーム部材１１，１２の一端側を固定し、火災を検知したときに固定状態が開放されるように、受熱によって溶融する材料、例えば温度ヒューズ（可溶合金）が用いられる。温度ヒューズは、銅板と銅板を可溶合金で溶接したもので、加熱された場合に、熱導伝率の高い銅板が高温となり、可溶合金が溶融することで、接着していた銅板同士が離れて固定状態が開放されることとなる。この可溶合金の溶融温度は、例えば合金の組成比を調整することで、通常状態では溶融せず、火災を検知したときに溶融するように設定されている。 A heat sensing member 15 is provided on one end side of the first and second arm members 11 and 12. The heat sensing member 15 fixes one end side of the first and second arm members 11 and 12, and is a material that melts by receiving heat so that the fixed state is released when a fire is detected, for example, a thermal fuse (soluble). Alloy) is used. A thermal fuse is made by welding a copper plate and a copper plate with a soluble alloy. When heated, the copper plate with high heat conductivity becomes hot and the soluble alloy melts, causing the bonded copper plates to bond to each other. The fixed state will be released apart. The melting temperature of this soluble alloy is set so that it does not melt in a normal state but melts when a fire is detected, for example, by adjusting the composition ratio of the alloy.

熱感知部材１５の一端は、ボルト２４−１とナット２４−２により第１アーム部材１１の一端に取り付けられ、他端はボルト２５−１とナット（図示しない）により第２アーム部材１２の一端に取り付けられる。第１アーム部材１１の他端側の第２アーム部材１２との対向部には、端部側が大きくなるように切り欠いたテーパ１１ａが形成されており、第１、第２アーム部材１１，１２の一端側が大きく開くようになっている。 One end of the heat sensing member 15 is attached to one end of the first arm member 11 by bolts 24-1 and nuts 24-2, and the other end is attached to one end of the second arm member 12 by bolts 25-1 and nuts (not shown). Attached to. A taper 11a is formed on the other end side of the first arm member 11 facing the second arm member 12 so that the end side becomes larger, and the first and second arm members 11 and 12 are formed. One end side of is wide open.

連結部材１３，１４で連結され、熱感知部材１５で一端側が固定された第１、第２アーム部材１１，１２は、取付部材１６，１７によりバルブボディ４が閉成した状態で消火器本体１に取り付けられる。取付部材１６，１７は消火器本体１の側面に沿って配置されており、第１、第２アーム部材１１，１２と取付部材１６，１７は、ほぼ直交している。 The first and second arm members 11 and 12, which are connected by the connecting members 13 and 14 and whose one end side is fixed by the heat sensing member 15, are the fire extinguisher main body 1 in a state where the valve body 4 is closed by the mounting members 16 and 17. Attached to. The mounting members 16 and 17 are arranged along the side surface of the fire extinguisher main body 1, and the first and second arm members 11 and 12 and the mounting members 16 and 17 are substantially orthogonal to each other.

これら取付部材１６，１７は、本例ではアングル材であり、難燃性あるいは不燃性材料、例えば鉄やアルミニウム等の金属や金属合金から構成されているが、バルブボディ４が閉成した状態で消火器本体１に取り付けられれば、形状や構成、材料はこれらに限られるものではない。 These mounting members 16 and 17 are angle members in this example, and are made of a flame-retardant or non-flammable material such as a metal such as iron or aluminum or a metal alloy, but in a state where the valve body 4 is closed. If it is attached to the fire extinguisher main body 1, the shape, structure, and material are not limited to these.

更に、第１アーム部材１１を、熱感知部材１５を伸長する方向に付勢する弾性部材、本例ではコイルばね１８が設けられている。コイルばね１８の一端はボルト２６−１とナット２６−２で第１アーム部材１１の他端側に係止され、他端はボルト２７−１とナット２７−２で取付部材１６，１７に係止される。これによって、第１アーム部材１１の他端側を、熱感知部材１５を伸長する方向に付勢するようになっている。 Further, an elastic member that urges the first arm member 11 in the direction of extending the heat sensing member 15, in this example, a coil spring 18 is provided. One end of the coil spring 18 is locked to the other end side of the first arm member 11 by the bolt 26-1 and the nut 26-2, and the other end is engaged with the mounting members 16 and 17 by the bolt 27-1 and the nut 27-2. It will be stopped. As a result, the other end side of the first arm member 11 is urged in the direction in which the heat sensing member 15 is extended.

上述したような構成の自動消火器１００は、図４（ａ）に示すような状態で設置される。そして、火災により熱感知部材１５が加熱され、この熱感知部材１５が受熱によって溶融することで、第１、第２アーム部材１１，１２の一端側の固定状態が開放されると、図４（ｂ）に示すようにコイルばね１８により第１アーム部材１１が付勢され、弁棒８が下方に押されてバルブボディ（容器弁）４を開き、自動消火器１００が作動して消火薬剤２が噴出するようになっている。 The automatic fire extinguisher 100 having the above-described configuration is installed in the state shown in FIG. 4 (a). Then, when the heat sensing member 15 is heated by the fire and the heat sensing member 15 is melted by receiving heat, the fixed state on one end side of the first and second arm members 11 and 12 is released. As shown in b), the first arm member 11 is urged by the coil spring 18, the valve rod 8 is pushed downward to open the valve body (container valve) 4, and the automatic fire extinguisher 100 operates to extinguish the fire agent 2. Is supposed to spurt out.

従って、このような構成によれば、電源や電気回路を用いることなく、火災を感知したときに自動で初期消火を行うことができる。このため、定期的な点検や保守を少なくでき、停電しても作動する。 Therefore, according to such a configuration, the initial fire extinguishing can be automatically performed when a fire is detected without using a power supply or an electric circuit. Therefore, regular inspections and maintenance can be reduced, and the product operates even if there is a power failure.

また、組み合わせる既存の消火器を自由に選択できるので、消火薬剤（粉末、液体、ガス等）と薬剤容量などを設置条件や用途に合わせることで、汎用性を高めて幅広い現場ニーズに対応することができる。 In addition, since the existing fire extinguisher to be combined can be freely selected, it is possible to improve versatility and meet a wide range of on-site needs by adjusting the fire extinguishing agent (powder, liquid, gas, etc.) and the chemical capacity according to the installation conditions and applications. Can be done.

更に、熱を感知する部分とノズルの位置を、消火器を設置する空間の形状や配置に応じて自由に設定でき、ケーブル洞道などに配置する場合に様々な場所に設置できる。加えて、広く利用されている既存の消火器を利用することで、コストダウンを図れるだけでなく、品質や安全面での信頼性を確保できる。 Furthermore, the position of the heat-sensing part and the nozzle can be freely set according to the shape and arrangement of the space in which the fire extinguisher is installed, and can be installed in various places when it is arranged in a cable tunnel or the like. In addition, by using an existing fire extinguisher that is widely used, not only cost reduction can be achieved, but also reliability in terms of quality and safety can be ensured.

図５は、本発明の変形例について説明するためのもので、消火器周辺の機構を説明するために、消火器の収納ケース３０の一部を切り欠いて内部構成を示している。また、図６は、図５におけるロック機構と解除機構の構成例を示す正面図、側面図、内部の正面図である。 FIG. 5 is for explaining a modification of the present invention, and in order to explain the mechanism around the fire extinguisher, a part of the storage case 30 of the fire extinguisher is cut out to show the internal configuration. Further, FIG. 6 is a front view, a side view, and an internal front view showing a configuration example of the lock mechanism and the release mechanism in FIG.

本変形例においては、市販の消火器２００に自動消火のための各種の機構を設置しており、火災の感知部は上述した実施形態と同様な構成（図示を省略する）であり、消火器２００とは分離されている。 In this modification, various mechanisms for automatic fire extinguishing are installed in a commercially available fire extinguisher 200, and the fire detection unit has the same configuration as the above-described embodiment (not shown), and the fire extinguisher. It is separated from 200.

即ち、上述した実施形態では、自動起動機構を取付部材１６，１７により直接消火器本体１に取り付けていたが、本変形例では自動起動機構から離隔して消火器２００を設置できるようにしている。 That is, in the above-described embodiment, the automatic start mechanism is directly attached to the fire extinguisher main body 1 by the mounting members 16 and 17, but in this modification, the fire extinguisher 200 can be installed separately from the automatic start mechanism. ..

One end of a coil spring 18 as a first elastic member is connected to a bolt 26-1 and a nut 26-2 on the other end side of the first arm member 11 of the automatic start mechanism via a control wire 32, and the coil spring 18 is connected to the bolt 26-1 and the nut 26-2. The other end of 18 is fixed to the bottom of the storage case 30.

また、消火器２００のバルブボディ４を開く起動レバー３３を作動方向に付勢する第２弾性部材として働くコイルばね３４が、レバーワイヤー３５を介して収納ケース３０の底部にボルト２８−１とナット２８−２，２８−３により固定されている。 Further, a coil spring 34 that acts as a second elastic member that urges the start lever 33 that opens the valve body 4 of the fire extinguisher 200 in the operating direction is provided with a bolt 28-1 and a nut at the bottom of the storage case 30 via the lever wire 35. It is fixed by 28-2 and 28-3.

更に、コイルばね３４により消火器２００の起動レバー３３が作動するのを抑止するロック機構３６と、火災により熱感知部材が加熱され、第１、第２アーム部材１１，１２の一端側の固定状態が開放され、コイルばね１８によって第１アーム部材１１の他端側が閉じたときに、ロック機構３６を解除する解除機構３７が設けられている。ロックが解除されると、コイルばね３４により消火器２００の起動レバー３３が付勢されて消火器２００が作動する。 Further, a lock mechanism 36 for suppressing the activation of the start lever 33 of the fire extinguisher 200 by the coil spring 34 and a fixed state on one end side of the first and second arm members 11 and 12 when the heat sensing member is heated by the fire. Is released, and a release mechanism 37 for releasing the lock mechanism 36 is provided when the other end side of the first arm member 11 is closed by the coil spring 18. When the lock is released, the coil spring 34 urges the start lever 33 of the fire extinguisher 200 to operate the fire extinguisher 200.

ロック機構３６は、レバーワイヤー３５を介してコイルばね３４により消火器２００のバルブボディ４を開く起動レバー３３が作動方向に付勢されるのをロックする掛金３８を備えている。 The lock mechanism 36 includes a latch 38 that locks the start lever 33 that opens the valve body 4 of the fire extinguisher 200 by the coil spring 34 via the lever wire 35 in the operating direction.

また、解除機構３７は、熱感知部材１５の受熱によって、第１、第２アーム部材１１，１２の一端側が開放され、コイルばね１８によって第１、第２アーム部材１１，１２の他端側が閉じたときに、掛金３８を解放してロック機構３６を解除するラッチレバー３９と、第１、第２アーム部材１１，１２の一端側が閉成している（他端側が開いている）ときに、ラッチレバー３９を固定するストッパー４０とを含んでいる。 Further, in the release mechanism 37, one end side of the first and second arm members 11 and 12 is opened by the heat reception of the heat sensing member 15, and the other end side of the first and second arm members 11 and 12 is closed by the coil spring 18. When the latch lever 39 that releases the latch 38 to release the lock mechanism 36 and one end side of the first and second arm members 11 and 12 are closed (the other end side is open), It includes a stopper 40 for fixing the latch lever 39.

上記のような構成において、自動消火器の設置状態では、図７（ａ），（ｂ）に示すようになっており、熱感知部材１５が受熱によって溶融すると、図７（ｃ），（ｄ）に示すようにコントロールワイヤー３２が緩み、ロック機構３６のストッパー４０がコイルばね１８に引かれて下がってロックが外れる。これによって、ストッパー４０に固定されていたラッチレバー３９が作動し、図７（ｅ），（ｆ）に示すようにラッチレバー３９で止まっていた掛金３８がコイルばね３４に引かれて下がる。そして、掛金３８がレバーワイヤー３５を引き、起動レバー３３が引かれて消火器２００が作動し、消火薬剤２が噴出する。 In the above configuration, when the automatic fire extinguisher is installed, it is as shown in FIGS. 7 (a) and 7 (b), and when the heat sensing member 15 is melted by receiving heat, FIGS. 7 (c) and 7 (d). ), The control wire 32 is loosened, the stopper 40 of the lock mechanism 36 is pulled by the coil spring 18 and lowered, and the lock is released. As a result, the latch lever 39 fixed to the stopper 40 operates, and as shown in FIGS. 7 (e) and 7 (f), the latch 38 stopped by the latch lever 39 is pulled down by the coil spring 34. Then, the latch 38 pulls the lever wire 35, the start lever 33 is pulled, the fire extinguisher 200 operates, and the fire extinguishing agent 2 is ejected.

上記のような構成によれば、電源や電気回路を用いることなく、火災を感知したときに自動で初期消火を行うことができる。このため、定期的な点検や保守を少なくでき、停電しても作動する。また、火災による熱を感知する部分とノズルの位置を、消火器２００を設置する空間の形状や配置に応じて自由に設定でき、ケーブル洞道などに配置する場合に様々な場所に設置できる。 According to the above configuration, the initial fire extinguishing can be automatically performed when a fire is detected without using a power supply or an electric circuit. Therefore, regular inspections and maintenance can be reduced, and the product operates even if there is a power failure. Further, the position of the portion that senses heat from the fire and the position of the nozzle can be freely set according to the shape and arrangement of the space in which the fire extinguisher 200 is installed, and can be installed in various places when arranged in a cable tunnel or the like.

更に、比較的単純で火災の感知部と消火器２００本体とが分離できるので、より設置の自由度が高く、火災時に人が入れない場所や、入るために時間を要する場所などにも容易に設置でき、火災を感知したときに自動で初期消火を行うことができる。 Furthermore, since it is relatively simple and the fire detector and the fire extinguisher 200 body can be separated, the degree of freedom of installation is higher, and it is easy to put in places where people cannot enter in the event of a fire or where it takes time to enter. It can be installed and the initial fire extinguishing can be performed automatically when a fire is detected.

しかも、サイズや形状が異なる消火器にも容易に適用できる。加えて、広く利用されている既存の消火器を利用することで、コストダウンを図れるだけでなく、品質や安全面での信頼性を確保できる。 Moreover, it can be easily applied to fire extinguishers of different sizes and shapes. In addition, by using an existing fire extinguisher that is widely used, not only cost reduction can be achieved, but also reliability in terms of quality and safety can be ensured.

尚、本発明は上述した実施形態に限定されるものではなく、要旨を逸脱しない範囲で種々変形して実施することが可能である。 The present invention is not limited to the above-described embodiment, and can be modified in various ways without departing from the gist.

例えば、第１アーム部材１１で熱感知部材１５を伸長する方向に引っ張り、弁棒８を押圧して消火器本体１のバルブボディ４を開放する場合を例に取って説明したが、第１アーム部材１１で熱感知部材１５を圧縮し、弁棒８を引き上げて消火器本体１のバルブボディ４を開放するように構成することもできる。 For example, the case where the heat sensing member 15 is pulled by the first arm member 11 in the extending direction and the valve rod 8 is pressed to open the valve body 4 of the fire extinguisher main body 1 has been described as an example. The heat sensing member 15 may be compressed by the member 11, and the valve rod 8 may be pulled up to open the valve body 4 of the fire extinguisher body 1.

また、熱感知部材１５が、火災による受熱によって溶融することで、第１、第２アーム部材１１，１２の一端側を開放又は閉成する場合を例に取って説明したが、受熱によって伸長、変形、破断、蒸発（焼失）する部材の場合にも実質的に同様な作用効果が得られる。 Further, the case where the heat sensing member 15 melts due to heat reception due to a fire to open or close one end side of the first and second arm members 11 and 12 has been described as an example. Substantially the same effect can be obtained in the case of a member that is deformed, broken, or evaporated (burned out).

更に、消火器本体が蓄圧式を例に取って説明したが、加圧式や他の構成の消火器を用いても良いのは勿論である。 Further, although the fire extinguisher main body has been described by taking the accumulator type as an example, it is needless to say that a pressurized type or a fire extinguisher having another configuration may be used.

本発明は、例えば、ケーブル洞道などのように、火災時に人が入れない場所や入るために時間を要する場所に設置することで、火災を感知したときに自動で初期消火を行うことができ、産業上有用である。 The present invention can automatically extinguish an initial fire when a fire is detected by installing it in a place where people cannot enter or it takes time to enter, such as a cable tunnel. , Industrially useful.
