Description

【０００１】
【発明の属する技術分野】
本発明は消火器の錠装置に関し、特に消火器を普段施錠することができる消火器の錠装置に関する。
【０００２】
【従来の技術】
従来、消火器は、例えば「消火器ボックス」に設置されている。消火器は緊急時に使用されるものであるから、誰でも消火器ボックスから消火器を自由に持ち出すことができる。ところが、近年、消火器ボックスから消火器を故意あるいは無断で持ち出し、かつ、これを高層マンションから落下し、人身事故が発生するという問題が起き上がっている。
【０００３】
【発明が解決しようとする課題】
本発明の課題は、従来の技術の背景に鑑み、消火器ボックスなどから消火器が無断に持ち出されないことである。そこで、本発明の具体的課題は次に列挙する通りである。
（１）緊急時以外は消火器を常に錠装置で施錠できること。
（２）緊急時には、直ちに錠装置用緊急解錠信号送信機を操作して錠装置を解錠することができること。つまり、火災が発生した場合には、普通の一般的な身長を有する人が指で緊急解錠信号送信機を操作すると、錠装置が直ちに解錠し、消火器を持ち出すことができること。
（３）錠装置が解錠した場合、消火器の存在の有無を人の視覚ないし聴覚に訴えることができること。
（４）錠装置を必ずしも火災監視室に設置された自動火災報知受信機にケーブルを介して接続しなくとも、所望する時に錠装置側の緊急解錠信号送信機を操作すると、錠装置が独自にその施錠状態を解消することができること。
（５）錠装置を合理的に構成し、部材点数を極力少なくすることができること。
【０００４】
【課題を解決するための手段】
本発明の消火器の錠装置は、建物或いは建物の近くに設置された収納体２２と、この収納体２２に設置された消火器２１を常時施錠する錠装置の主要部４０とから成り、前記錠装置の主要部４０は、収納体２２側に固定されていると共に、ガイド孔５７を有する第１ガイド支持板５５並びに該第１ガイド支持板５５に一体的に設けられかつ係止窓６１を有する第２ガイド支持板５９から成るガイド部材５４と、収納体２２側に枢着された連結板４４を介して消火器２１と対向するように設けられた前方開閉板４６と、この前方開閉板に枢着されかつ前記第１ガイド支持板５５のガイド孔５７に挿入される差込み係合板４９と、この差込み係合板４９を前記第２ガイド支持板５９の係止窓６１を介して施錠するように収納体２２側に枢支され、かつ、収納体２２側に固定された駆動源６２の駆動力により係合解除の方向へ回転する係合爪片６５とを備え、少なくとも前記収納体２２、前方開閉板４６、消火器の設置してある付近のいずれかには、錠装置用緊急解錠信号送信機２６が設けられており、この緊急解錠信号送信機２６を操作すると、人の視覚ないし聴覚に訴える報知手段３７が、少なくとも緊急解錠信号送信機２６、収納体２２、建物の壁Ｗ、建物の天井のいずれか１つに設置されていることを特徴とする（請求項１）。

【０００７】
上記の場合、錠装置の主要部を収納体に取付けても良いし、また駆動源６２Ｂの作動杆６３Ｂを直接係合手段８２の差込み板４９Ｂに係合させても良い。
【０００８】
また本発明の消火器の錠装置は、建物或いは建物の近くに設置されたボックス状収納体２２Ｃに取付けられる錠装置の主要部４０Ｃと、一方、この錠装置の主要部４０Ｃと係脱する係合手段８２Ｃを一体的に有すると共に収納体２２Ｃ内に設置された消火器２１Ｃとから構成され、前記錠装置の主要部４０Ｃは、駆動源６２Ｃと、この駆動源６２Ｃの作動杆６３Ｃにより回動するように一端部が枢支された係合爪片６５Ｃと、前壁８６に窓状の挿入孔８７を有するカバー８４Ｃとから成り、また前記係合手段８２Ｃは、一端部が消火器２１Ｃに一体的に取付けられた可撓性部材８９と、この可撓性部材８９の他端部に一体的に取付けられかつ前記挿入孔８７に差し込まれた状態で係止窓６１を有するガイド支持板５９に対して位置すると共に、前記係止窓６１を介して係合爪片６５Ｃに係止された差込み係合板４９Ｃとから成り、少なくとも前記カバー８４Ｃ、収納体２２Ｃ、消火器の設置してある付近のいずれかには、錠装置用緊急解錠信号送信機２６Ｃが設けられており、この緊急解錠信号送信機２６Ｃを操作すると、人の視覚ないし聴覚に訴える報知手段３７が、少なくとも緊急解錠信号送信機２６Ｃ、収納体２２Ｃ、建物の壁、建物の天井のいずれか１つに設置されていることを特徴とする（請求項７）。
【０００９】
また本発明の消火器の錠装置は、建物或いは建物の近くに設置された収納体２２Ｄと、この収納体２２Ｄに設置された消火器２１Ｄを常時施錠する錠装置の主要部４０Ｄとから成り、前記錠装置の主要部４０Ｄは、係止窓６１を有するガイド支持板５９Ｄを一体的に備えかつ収納体２２Ｄ側に固定されたベース部材４１Ｄと、このベース部材４１Ｄの一端部に枢着されたベルト状前方開閉板４６Ｄと、この前方開閉板４６Ｄの他端部に一体的に設けられかつベース部材４１Ｄの他端部に形成されたガイド孔５７Ｄに挿入される差込み係合板４９Ｄと、この差込み係合板４９Ｄを前記ガイド支持板５９Ｄの係止窓６１を介して施錠するように収納体２２側に枢支され、かつ、収納体２２側に固定された駆動源６２Ｄの駆動力により係合又は係合解除の方向へ回転する係合爪片６５Ｄとを備え、少なくとも前記収納体２２Ｄ、前方開閉板４６Ｄ、消火器の設置してある付近のいずれかには、錠装置用緊急解錠信号送信機２６が設けられており、この緊急解錠信号送信機２６を操作すると、人の視覚ないし聴覚に訴える報知手段３７が、少なくとも緊急解錠信号送信機２６、収納体２２Ｄ、前方開閉板４６Ｄ、建物の壁、建物の天井のいずれか１つに設置されていることを特徴とする（請求項９）。
【００１０】
【発明の実施の形態】
以下、図面に示す本発明の実施の形態を、建物或いは建物の近く（歩道も含む。）に設置された消火器との関係で説明する。
【００１１】
図１ないし図６に於いて、Ｘは本発明が適用される消火器の錠装置の第１実施例である。まず図中符号２１は主としてアパート、マンションなど主として建物に設置される消火器である。次に２２は消火器用のボックス状収納体で、この収納体２２の前面は開口２３していると共に、開口部２３の上方に垂直板２４が設けられている。この収納体２２は後述する錠装置の一部を構成する。
【００１２】
２５は前記垂直板２４に形成された嵌合孔で、この嵌合孔２５にはプッシュ式緊急解錠信号送信機２６が嵌着している。この緊急解錠信号送信機２６は、本実施例では火災報知機としての機能も有し、図２で示すように前面の中央部に透明カバー２７を有する。また前面の適宜部位には警報ブザー用の複数個の透孔２８が形成されている。また透明カバー２７の後方には所要空間を有して縦方向にプリント基板２９が設けられ、このプリント基板２９の中心孔３０には水平方向にプッシュ移動可能な摺動子３１が嵌挿している。またプリント基板２９の後方と緊急解錠信号送信機２６の後面との間には、摺動子３１の溝と接触している可動接片３２を有するスイッチ３３が設けられ、このスイッチ３３には出入力端子３４が設けられている。さらに、プリント基板２９の前方側の適宜部位には、点灯・点滅ランプ、非常ベル、ブザーなど報知手段の一例である警報ブザー３７が取付けられ、この警報ブザー３７にも出入力端子３４が設けられている。３５は収納体２２の上面壁２２ｂの適宜部位に形成されたボックス状の電源収納部である。
【００１３】
ところで、収納体２２は、一般に開口部の大きさやその形態を如何を問わず「消火器ボックス」と俗称され、壁埋め込み式タイプ、床置き式タイプ、壁掛け式タイプなどがあり、また前面開口型と開閉扉を有する前面非開口型とがあり、さらに、移動型と非移動型がある。本実施例の収納体２２はこれらのタイプを全て意味する。
【００１４】
次に図３乃至図６に基づき錠装置の主要部４０について説明する。まず４１はボックス状収納体２２の背面壁２２ａの略中央部に水平状態に固定された長板状のベース板である。ベース板４１は、この実施例では収納体２２の背面壁２２ａとは別体に形成されているが、もちろん収納体２２の背面壁２２ａの一部であっても良い。このベース部材としてのベース板４１は端面コ字型状に形成され、上下の対向壁４２、４２の右側端部４２ａは、その左側の枢支端部４２ｂよりも幅広に形成されていると共に、対向壁４２、４２の中央部は消火器１の外周面に線接触するようにやや弧状に切欠されている。なお、このベース板４１の垂直壁４３には特に符号を付さないが、固着具用、接続コード用、枢支ピン用などの複数個の貫通孔が形成されている。
【００１５】
４４は第１枢支ピン４５を介してベース板４１に枢着された端面コ字型状の連結板である。４６はベース板４１と対向するように第２枢支ピン４７を介して連結板４４に枢支された長板状の前方開閉板である。この前方開閉板４６はベース板４１と同一の長さであり、またベース板４１と同様に端面コ字型に形成されていると共に、対向する上下の対向壁４８の中央部は消火器２１の外周面に線接触するようにやや弧状に切欠されている。
【００１６】
４９は連結板４４と対向するように第３枢支ピン５０を介して前方開閉板４６に枢支された長板状の差込み係合板である。この差込み係合板４９も端面コ字型に形成されている。しかして、差込み係合板４９の自由端部はやや先細り状に形成されていると共に、その垂直壁５１の端部には係合部としての係合孔５２が形成されている。この様にベース板４１を中心として、連結板４４、前方開閉板４６及び差込み係合板４９は、消火器２１を取り囲む格好となる。
【００１７】
次に５４はベース板４１の対向壁４２の右側端部４２ａに固定されたガイド部材で、このガイド部材５４は、この実施例では第１ガイド支持板５５と、第２ガイド支持板５９とから成る。第１ガイド支持板５５は任意に折曲形成され、ベース板４１の垂直壁４３と所要空間を有して対向する垂直壁部５６には、縦長のガイド孔５７及び後述する係合爪片６５用枢支孔５８が適宜に形成されている。
【００１８】
一方、ベース板４１の垂直壁４３の右側端部４２ａと第１ガイド支持板５５の垂直壁部５６との所要空間内に固定的に設けられた第２ガイド支持板５９は端面Ｕ字型状に形成されている。この第２ガイド支持板５９は図５で示すように横に倒した状態で、その内部空間６０がガイド支持板５５のガイド孔５７と連通するように第１ガイド支持板５５に一体的に取付けられている。しかして、第２ガイド支持板５９には図４で示すように差込み係合板４９の自由端部の係合孔５２と対向（符合）可能な係合部としての係止窓６１が形成されている。
【００１９】
６２はベース板４１の対向壁４２の右側端部４２ａ内に固定的に設けられた駆動源としてのソレノイドである。このソレノイド６２は第１ガイド支持板５５と第２ガイド支持板５９との間にその作動杆６３が上下動するように縦設されている。そして、本実施例ではこのソレノイド６２及びプッシュ式緊急解錠信号送信機２６は、収納体２２の電源収納部３５に直列回路で接続されている。
【００２０】
６５はベース板４１及び第１ガイド支持板５５に枢支孔５８を介して枢支されたラッチとしての係合爪片である。この係合爪片６５はベース板４１の下方側の対向壁４２と対向する水平部６６に長孔６７を有すると共に、水平部６６の一端部に連設する垂直部６８には、第２ガイド支持板５９の係止窓６１及び差込み係合板４９の係合孔５２とそれぞれ係合する爪部６９が折曲形成されている。
【００２１】
７０は係合爪片６５の水平部６６の長孔６７を貫通したソレノイド６２の作動杆６３の突出下端部に設けられたストッパーピンである。このストッパーピン７０は作動杆６３の突出下端部を水平状態に貫通し、かつ、係合爪片６５の水平部６６の下面と当接し、係合爪片６５を回転させる駆動ピンとしての機能を果たす。
【００２２】
７１はソレノイド６２の作動杆６３に設けられ、かつ、係合爪片６５の爪部６９を第２ガイド支持板５９の係止窓６１及び差込み係合板４９の係合孔５２に係合（施錠）するように常時付勢する付勢バネである。
【００２３】
上記構成に於いては、所望する建物或いは建物の近くに消火器２１を入れた錠装置Ｘを設置する。そして、収納体２２の電源収納部３５に電池等の電源を入れる。本実施例では緊急解錠信号送信機２６のスイッチ３３の出力端子３４、ソレノイド６２、警報ブザー３７の出入力端子はそれぞれ直列回路で電気的に接続されているが、図示しない建物の監視室に設置された自動火災報知受信機にケーブルを介し、前記スイッチ３３の出入力端子３４、ソレノイド６２、警報ブザー３７の出入力端子をそれぞれ適当な電気回路で接続しても良い。
【００２４】
そこで、今仮に火災が発生し、図示しない天井、壁などの火災報知機が作動するのを待つまでもなく、誰でも所望する時は、収納体２２の緊急解錠信号送信機２６の摺動子３１を透明カバー２７の表面から力強く押す。これにより摺動子３１がスイッチ３３をＯＮの状態にし、緊急解錠信号が電気回路に流れる。
【００２５】
そこで、錠装置Ｘのソレノイド６２が通電状態になると、作動杆６３はバネ７１のバネ力に抗して収縮する。そうすると、係合爪片６５の水平部６６の長孔部は、ストッパーピン７０を介して上方に持ち上げられ、その結果、係合爪片６５はロック解除の方向へと回転し、その爪部６９が第２ガイド支持板５９の係止窓６１及び差込み係合板４９の係合孔５２から外れる（自動解錠）。そこで、前方開放板４６に手を掛けて手前側に引くと、差込み係合板４９の自由端部がガイド支持板５５から外れ、消火器２１を収納体２２から取り出すことができる。そして、この実施例の場合緊急解錠信号送信機２６の出入力端子３４に電気信号が送られてくるので、ブザー停止信号がプリント基板２９側に伝送されてこない限り、警報ブザー３７が鳴り続ける。なお、この実施例の電気回路には警報ブザー３７を鳴動を停止させることができるリセット回路を接続しても良い。
【００２６】
【実施例】
まず発明の実施の形態で説明した第１実施例も含め、後述する各実施例に於いては、駆動源としてのソレノイド６２に代え、駆動軸が上下動する駆動モータを用いても良い。また収納体２が開閉扉を有する前面非開口型の場合に於いては、前方開閉板４６は開閉扉自体であっても良い。したがって、このような実施例の場合は開閉扉自体の開放側端部の中央部に差込み係合板４９が水平状態に枢支されている。また緊急解錠信号送信機２６には警報ブザー３７が内臓されているが、警報ブザー３７を緊急解錠信号送信機２６とは別体にし、収納体２２の垂直板２４、錠装置の前方開閉板４６、建物の壁、建物の天井などに適宜取付けても良い。さらに、差込み係合板４９の自由端部は必ずしも端面がコ字型である必要はなく、単なる板状であっても良い。
【００２７】
次に図７乃至図１８は本発明の他の実施例を示す消火器の錠装置である。なお、これらの実施例の説明にあたって、本発明の前記第１実施例と同一の部分には同一の符号を付して重複する説明を省略する。
【００２８】
まず図７及び図８に示す消火器の錠装置Ｘ１の第２実施例に於いて、前記第１実施例と主に異なる点は、収納体２２Ａがボックス状ではなく、建物の壁Ｗに固定できるように取付け板にしたことである。すなわち、７５は取付け板２２Ａのベース部としての背面壁２２ｂに形成された複数個の固着具用貫通孔で、取付け板２２Ａは固着具７６を介して壁Ｗに固着される。したがって、取付け板２２Ａは壁Ｗに固定できるのであれば特に形態は問わない。
【００２９】
次に図９乃至図１２に示す消火器の錠装置Ｘ２の第３実施例に於いて、前記第１実施例と主に異なる点は、建物の床面Ｆに支持台８０を置き、この支持台８０に形成された嵌合凹所８１に消火器２１Ｂを設置したことである。また消火器２１Ｂを常時施錠している錠装置の主要部４０Ｂを建物の壁Ｗ１に取付け、一方、錠装置の一部を構成する係合手段８２が前記消火器２１Ｂに一体的に取付けられていることである。
【００３０】
しかして、錠装置の主要部４０Ｂについて説明すると、４１Ｂは壁Ｗ１に複数個の固着具８３を介して固定されたベース部材としてのベース板で、このベース板４１Ｂは、断面あるいは端面がコ字型状に形成されている。このベース板４１Ｂにも固着具用、接続コード用、枢支ピン用などの複数個の貫通孔が形成されているが特に符号を付して説明しない。
【００３１】
８４はベース板４１Ｂに複数個の固着具８５を介して固定されるボックス状のカバーである。このカバー８４は、背面が開口しており、また前壁８６の下部には横方向に窓状の挿入孔８７が形成されている。そして、前壁８６の上端部には嵌合孔２５Ｂを有する垂直板２４Ｂが突出形成されており、第１実施例と同様に前記嵌合孔２５Ｂにはプッシュ式緊急解錠信号送信機２６Ｂが嵌着している。
【００３２】
５９Ｂはベース板４１Ｂの垂直壁４３Ｂの下端部に固定された端面Ｕ字型状のガイド支持板或いは係止板である。このガイド支持板５９Ｂは横に倒した状態でその内部空間６０Ｂがカバー８４の挿入孔８７と連通するようにベース板４１Ｂに一体的に取付けられている。６１Ｂはガイド支持板５９Ｂに形成された係止窓で、この係止窓６１Ｂは上方に指向している。そして、ガイド支持板５９Ｂの上下の各先端部は外方向に開くように折曲形成されている。
【００３３】
６２Ｂはベース板４１Ｂの垂直壁４３Ｂの上部に固定されたソレノイドである。このソレノイド６２Ｂは、その作動杆６３Ｂが上下動するように縦設されている。そして、ソレノイド６２Ｂはカバー８４の上壁に適宜に設けられた電源収納部３５Ｂと電気的に接続されている。
【００３４】
６５Ｂはベース板４１Ｂの垂直壁４３Ｂに一端部が枢支ピン８８を介して枢支されたラッチとしての係合爪片である。この係合爪片６５Ｂは上端面がＬ型状に折曲形成され、その折曲形成された自由端部には、ガイド支持板５９Ｂの係止窓６１Ｂ及び係合手段８２の一部を構成する差込み係合板４９Ｂの係合孔５２Ｂとそれぞれ係合する爪部６９Ｂが下方方向に突出形成されている。
【００３５】
前記ソレノイド６２Ｂの作動杆６３Ｂは、枢支機能を有するストッパーピン７０Ｂを介して係合爪片６５Ｂの適宜部位に連結されている。７１Ｂは作動杆６３Ｂに設けられた付勢バネである。
【００３６】
そして、前記係合手段８２は、一端部が消火器２１Ｂに一体的に取付けられた鎖、ベルト、ロープなどの可撓性部材８９と、この可撓性部材８９の他端部に一体的に取付けられた差込み係合板４９Ｂとから成る。なお、この実施例に於いても、前述した第１実施例と同様にプッシュ式緊急解錠信号送信機２６Ｂの警報ブザー３７を建物の壁Ｗ１や天井に取付けても良い。またベース板４１Ｂを使用しないで壁Ｗ１そのものをベース部としても良い。この場合には背面開口のボックス状カバー８４に取付けフランジ部を形成すべきである。
【００３７】
上記構成に於いて、普段、消火器２１Ｂは支持台８０の嵌合凹所８１に設置され、かつ、係合手段８２の差込み係合板４９Ｂは主たる錠装置のガイド支持板５９Ｂの内部空間６０Ｂに差し込まれ、図９及び図１１で示すように係合爪片６５Ｂで係止（施錠）されている。したがって、消火器１Ｂを支持台８０から取り外しても、係合手段８２が主たる錠装置４０Ｂから外れない限り自由に持ち歩くことができない。
【００３８】
なお、この実施例に於いて、駆動源６２Ｂの作動杆６３Ｂは、係合爪片６５Ｂを介して係合手段８２の差込み板４９Ｂに間接的に係合しているが、係合爪片６５Ｂを使用しないで作動杆６３Ｂを直接差込み板４９Ｂに係合させても良い。
【００３９】
次に図１３及び図１４に示す消火器の錠装置Ｘ３の第４実施例に於いて、前記第１実施例と主に異なる点は、言わば第１実施例の収納体と第３実施例の錠装置とをプラスした実施例である。したがって、この錠装置Ｘ３の説明に当たっては便宜上収納体の構成に関して第１実施例と同一又は同様の符号を付し、一方、錠装置Ｘ３の主要部４０Ｃの構成に関して第３実施例と同一又は同様の符号を付し、重複する説明を省略する。
【００４０】
しかして、２１Ｃは消火器、２２Ｃはボックス状収納体、２６Ｃはプッシュ式緊急解錠信号送信機、８２Ｃは係合手段、８４Ｃはカバー、６２Ｃはソレノイド、である。６３Ｃはソレノイドの作動杆、６５Ｃは係合爪片、４９Ｃは差込み片である。
【００４１】
ところで、この第４実施例に於いては、第３実施例のベース板に相当する部分は収納体２２Ｃの背面壁２２ａである。また第３実施例の嵌合孔を有する垂直板に相当する部分は収納体２２Ｃの垂直板２４Ｃである。したがって、電源収納部３５Ｃはカバー８４Ｃの上壁ではなく、収納体２２Ｃの上面壁２２ｂに設けられている。さらに、第３実施例で示した消火器用支持台は設けられていない。
【００４２】
次に図１６乃至図１８に示す消火器の錠装置Ｘ４の第５実施例に於いて、前記第１実施例と主に異なる点は、前方開閉板４６Ｄがベルト状に形成され、その一端部が枢支ピン４５Ｄを介してベース部材４１Ｄに枢支されていると共に、他端部には差込み係合板４９Ｄが一体的に設けられていることである。なお、前方開閉板４６Ｄは、弾性乃至弾発力を有する。したがって、前方開閉板４６Ｄは錠装置Ｘ４が解錠状態に成った時、その材質自体の弾性乃至弾発力により長箱９１から飛び出すことができる。
【００４３】
またベース部材４１Ｄがボックス状収納体２２Ｄの背面壁２２ａの略中央部に水平状態に固定された長板状の裏蓋９０と、この裏蓋９０に固定的に取付けられた長箱９１とから成り、前記長箱９１の消火器２１Ｄの背面側の外周面と対向する外壁面９２はやや弧状に形成されていると共に、前方開閉板４６Ｄの一端部を枢支する枢支端部９１ａよりも、前方開閉板４６Ｄの差込み係合板４９Ｄが入り込むガイド孔５７Ｄを有する他端部９１ｂが大きめに形成されていることである。
【００４４】
しかして、長箱９１の他端部９１ｂ内には、ガイド支持板５９Ｄ、ソレノイド６２Ｄ、係合爪片６５Ｄ、付勢バネ７１Ｄなどが組込まれている。ところで、この錠装置Ｘ４のベース部材４１Ｄは収納体２２Ｄ内に取り付けられているが、錠装置の主要部４０Ｄを第３実施例のように壁に取り付ける場合は、ベース部材４１Ｄに垂直壁を形成し、これにプッシュ式緊急解錠信号送信機や電源収納部を取付けても良い。
【００４５】
なお、この第５実施例においては、消化器２１Ｄがボックス状の収納体２２Ｄ内に設置されており、また錠装置の主要部４０Ｄは収納体２２Ｄの背面壁２２ａに取付けられているが、第２実施例と同様に錠装置の主要部４０Ｄを壁に直接又は間接的に取付けても良い。
【００４６】
ところで、本発明の第１乃至第５実施例の説明に於いては、プッシュ式緊急解錠信号送信機を収納体２２、２２Ｃ、２２Ｄの垂直壁２４、取付け板２２Ａの垂直壁２４、前方開閉板４６、４６Ｄ、カバー８４の垂直壁２４Ｂ、などにそれぞれ取付けられる旨を説明したが、プッシュ式緊急解錠信号送信機は必ずしもこれらの垂直壁に装着される必要はなく、火災を直ちに報知するめに普通の一般的な身長を有する人が指で押すことができるのであれば、例えば消火器の設置してある付近の壁に取付けても良い。要はプッシュ式緊急解錠信号送信機２６、２６Ｂ、２６Ｃの摺動子３１を指で押圧すると、これに基づく電気信号によりソレノイドあるいは駆動モータが作動し、その結果、錠装置が自動的に解錠すれば良い。
【００４７】
【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、緊急時以外は消火器を常に錠装置で施錠できる、また緊急時には、直ちに錠装置用緊急解錠信号送信機を操作して錠装置を解錠すること、また錠装置が解錠した場合、消火器の存在の有無を人の視覚ないし聴覚に訴えることができる、さらに、錠装置を必ずしも火災監視室に設置された自動火災報知受信機にケーブルを介して接続しなくとも、所望する時に錠装置側の緊急解錠信号送信機を操作すると、錠装置が独自にその施錠状態を解消することができ、加えて、錠装置を合理的に構成し、部材点数を極力少なくすることができる。
