Description

【０００１】
【発明が属する技術分野】
この発明は、操作ボタンの取付構造に関するもので、特に石油ストーブの点火や消火を行う操作ボタンの取付構造に関するものである。
【０００２】
【従来の技術】
従来より、この種のものとして、例えば図６に示すように、１０１はしん式放射形の石油ストーブで、底板１０２と、天板１０３と、側板１０４と、前板１０５と、該前板１０５の上方に設けたガード１０６と、背面板（図示せず）とによりストーブ本体１０７が形成され、前記ガード１０６の内側には、前板１０５上部に水平方向に設けられた覆板１０８に取り付けられたしん式の燃焼筒１０９が設けられると共に、該燃焼筒１０９のまわりを覆うように反射板１１０が設けられている。
【０００３】
又前板１０５には、燃油の残量を表示する表示窓１１１と、燃焼筒１０９内のしん（図示せず）を上下させる調整つまみ１１２と、点火動作を行うために前板１０５の裏側に取り付けられた点火ボタン１１３と、該点火ボタン１１３を押すために前板１０５に開口された点火ボタン用開口部１１４と、消火動作を行うために前板１０５の裏側に取り付けられた消火ボタン１１５と、該消火ボタン１１５を押すために前板１０５に開口された消火ボタン用開口部１１６とが設けられているものである。
【０００４】
次にこのしん式放射形石油ストーブ１０１の操作について説明する。
まず着火する場合は、調整つまみ１１２を一番下まで押し下げて、燃焼筒１０９内のしんを点火位置まで上昇させて露出させ、次に点火ボタン１１３を押すと、ストーブ本体１０７内に設けた点火手段（図示せず）が動作して燃焼筒１０９内に露出しているしんに点火動作を行い、それによりしんが着火するもので、消火する場合は、消火ボタン１１５を押すと、消火ボタン１１５がストーブ本体１０７内に設けた耐震自動消火装置（図示せず）のおもり（図示せず）を倒し、それにより消火装置（図示せず）が動作して瞬時に消火を行うものである。
【０００５】
次に操作ボタンである点火ボタン１１３及び消火ボタン１１５の構造について説明する。
図７のように、操作ボタンの点火ボタン１１３及び消火ボタン１１５は背面が開口された略箱状で、ポリプロピレン等の合成樹脂よりなり、操作する際に指で押すための凸部１１７が形成されると共に、その凸部１１７を指で押した時に下端がストーブ本体１０７内に設けた停止片１１８に当接するボタン正面部１１９と、該ボタン正面部１１９の上部に位置し、上面に取り付け部１２０が形成されたボタン上部１２１と、前記ボタン正面部１１９とボタン上部１２１との境に形成された肉薄状の屈曲部１２２と、前記ボタン正面部１１９の左右両端に設けられ、屈曲部１２２の位置に切り欠き部１２３を形成すると共に、該切り欠き部１２３の下側の端で切り欠き部１２３の上側と当接する部分を傾斜して形成した当接部１２４を設けたボタン側面部１２５と、前記ボタン正面部１１９の下部に位置し、ボタン正面部１１９の凸部１１７を指で押した時、点火ボタン１１３なら点火装置に当接し、消火ボタン１１５なら耐震自動消火装置のおもりに当接して倒す作動片１２６が背面方向に形成されているボタン下部１２７とからなるものである。
【０００６】
前記ボタン上部１２１の取り付け部１２０は、正面から見て両端奥に形成されている係止片１２８と、正面から見て略中央に係止片１２８に対して前板１０５の板厚分だけ前方の位置に設けられている支持片１２９とからなり、又前記屈曲部１２２は、他の部分の厚さが約１．５ｍｍに対して０．２ｍｍと極めて薄く形成されているものである。
【０００７】
次に操作ボタンである点火ボタン１１３及び消火ボタン１１５の取り付け構造について、消火ボタン１１５を例に説明する。
図７、図８のように、前板１０５上部の折り曲げ部分に先端が折り曲げられて逆Ｌ字状に形成した折り曲げ部１３０を設け、この折り曲げ部１３０にボタン上部１２１の取り付け部１２０を差し込んで、係止片１２８と支持片１２９とが取り付け部１２０を挟持して前板１０５の背面側に取り付けられるものである。
【０００８】
【発明が解決しようとする課題】
ところでこの従来の操作ボタンでは、操作をするためボタン正面部の凸部を指で押すと、図９のように屈曲部がつぶれるように曲がってボタン正面部が傾斜し、それにより点火ボタンなら点火装置にボタン下部の作動片が当接して点火装置を作動させ、消火ボタンなら耐震自動消火装置のおもりに当接して倒すことにより消火装置を作動させるが、通常のボタン操作ではボタン側面部の当接部が切り欠き部の上側と当接すると共に、ボタン下部の下端がストーブ本体内に設けた停止片に当接することにより、それ以上ボタン正面部が傾斜しないようになっていた。
【０００９】
しかし、ボタン側面部の当接部が切り欠き部の上側と当接すると共に、ボタン下部の下端が停止片に当接している状態で、更にボタン正面部の凸部を強く指で押すと、当接部が切り欠き部の上側を押し上げ、それにより係止片と支持片とにより取り付け部を挟持していたのがゆるんで、操作ボタンが抜けて外れてしまったり、又ボタン上部が前板の折り曲げ部を曲げて当初の折り曲げ角度を変えてしまい、又屈曲部もつぶれた状態のままになるため、ボタン正面部から指を離しても図１０のように操作ボタンが当初の位置まで戻らないという問題があった。
【００１０】
本発明はこのような問題に鑑み、操作ボタンを必要以上の力で押しても、操作ボタンが外れてしまうのを防止すると共に、指を離すと同時に当初の位置まで戻る操作ボタンの取付構造を提供することを解決すべき課題とするものである。
【００１１】
【課題を解決するための手段】
本発明はこの点に着目し上記欠点を解決するため、特にその構成を、請求項１では、底板と、天板と、側板と、上部の折り曲げ部分に操作ボタンを取り付ける取付片を形成した前板と、該前板の上方に設けたガードと、背面板とによりストーブ本体が形成され、前記前板上部に水平方向に設けられ、先端部分を断面略コの字状に形成して前板上部と接する接合部を設けた覆板とを有する石油ストーブの操作ボタン取付構造に於いて、前記取付片の上面に重なる舌状の変形防止片を接合部に形成したものである。
【００１２】
又本発明の請求項２に係る石油ストーブの操作ボタン取付構造では、特にその構成を、請求項１に於いて、前記操作ボタン上部には、略Ｌ字状の短係合片と、該短係合片と対向する位置に先端が略くさび形の長係合片とを立設すると共に、前記取付片は、短係合片を差し込む短係合片用孔と、長係合片を差し込む長係合片用孔とを形成すると共に、前記長係合片用孔に長係合片の先端のくさび形の部分が係合する立設片を設けたものである。
【００１３】
又本発明の請求項３に係る石油ストーブの操作ボタン取付構造では、特にその構成を、請求項２に於いて、前記変形防止片は、短係合片と長係合片との間隔よりも若干小さい幅に形成されると共に、短係合片と長係合片との間隔に位置するように設けられたものである。
【００１４】
【発明の実施の形態】
前記構成による請求項１記載の石油ストーブの操作ボタン取付構造によれば、石油ストーブの前板に操作ボタンを取り付ける取付片を設け、前記前板上部に水平方向に設けられ、先端部分を断面略コの字状に形成して前板上部と接するように設けた覆板の接合部に、前記取付片の上面に重なる舌状の変形防止片を形成したものである。
【００１５】
これにより、操作ボタンを操作した時、操作ボタンを押す力を強くして操作ボタンが取付片を押し上げようとしても、取付片と重なっている変形防止片が、取付片が押し上がるのを防止し、それにより取付片が変形するのを防止できるものである。
【００１６】
前記構成による請求項２記載の石油ストーブの操作ボタン取付構造によれば、請求項１の石油ストーブの操作ボタン取付構造において、操作ボタン上部に略Ｌ字状の短係合片と、先端が略くさび形の長係合片とを対向させて立設し、取付片には短係合片用孔と、長係合片の先端のくさび形の部分が係合する立設片を設けた長係合片用孔とを形成したものである。
【００１７】
これにより、操作ボタンを強く押しても、取付片の立設片と長係合片先端のくさび形の部分との係合が容易に外れないので、操作ボタンを過度に操作しても操作ボタンが外れるのを防止できるものである。
【００１８】
前記構成による請求項３記載の石油ストーブの操作ボタン取付構造によれば、請求項２の石油ストーブの操作ボタン取付構造において、前記変形防止片を短係合片と長係合片との間隔よりも若干小さい幅に形成して短係合片と長係合片との間隔に位置するように設けたものである。
【００１９】
これにより、短係合片と長係合片とが外れる方向に動く、つまり内側に傾くのを変形防止片が規制するため、操作ボタンをまっすぐ押すのではなく、操作ボタンが外れるような斜めの方向に強く押しても、操作ボタンが外れるのを防止できるものである。
【００２０】
【実施例】
次に、この発明に係る操作ボタンを図面に示された一実施例で説明する。
なお、従来例と同じものは説明を省略するものとする。
１は操作ボタンで、ポリプロピレン等の合成樹脂よりなり、背面が開口された略箱状のボタン本体２と、操作ボタンを取り付ける取付部３と、前記ボタン本体２と取付部３との間に設けられ、側面から見てＵ字状に形成されて強い弾性を有するバネ部４とからなるものである。
【００２１】
前記ボタン本体２は、操作する際に指で押すための凸部５が形成されると共に、その凸部５を指で押した時に下端がストーブ本体内に設けた停止片６に当接するボタン正面部７と、該ボタン正面部７の上部に位置し、バネ部４のＵ字状の一端と一体化しているボタン上部８と、前記ボタン正面部７の左右両端に設けられたボタン側面部９と、ボタン正面部７の凸部５を指で押した時、点火ボタンなら点火装置に当接し、消火ボタンなら耐震自動消火装置のおもりに当接して倒す作動片１０が背面方向に形成されているボタン下部１１とからなるものである。
【００２２】
前記取付部３は、バネ部４のＵ字状の他端と一体化している取付部本体１２と、該取付部本体１２の上面の一端に立設した略Ｌ字状の短係合片１３と、取付部本体１２の上面の他端で前記短係合片１３と対向する位置に立設し先端が略半くさび形の長係合片１４とを立設すると共に、前記取付部本体１２の上面は前下がりで約５度の傾斜がつけられており、又前記短係合片１３の係合面１５及び長係合片１４の係合面１６にも前下がりで約５度の傾斜がつけられているものである。
【００２３】
前記バネ部４は、Ｕ字状の端部分の厚さが操作ボタン１の他の部分と同じ約１．５ｍｍであるのに対して、Ｕ字状の曲がり部分の厚さを約１ｍｍとし、更に正面から見て中央部分を抜いた状態に形成してあるので、バネ部４の強度を確保しつつ適切な弾性力を有すると共に、強い力で押しても押しつぶれることを防止でき、又ボタン本体２のボタン上部８とＵ字状の下部分に補強部１７を形成して、バネ部４の下部分とボタン上部８が常に平行になるようになっていて、押した力がバネ部４にかかるようになっているものである。
【００２４】
次に前記操作ボタン１の取り付け構造について説明する。
１８はしん式放射形石油ストーブの前板で、石油ストーブのストーブ本体は、前板１８と、底板と、天板と、側板と、該前板の上方に設けたガードと、背面板とにより形成され、前記前板１８の正面には取り付けた操作ボタン１の凸部５を指で押せるように開口部１９が形成され、又前板１８上部の折り曲げ部分に舌状に設けた取付片２０が形成されており、更に取付片２０には操作ボタン１の短係合片１３と長係合片１４とを差し込んで係合するための短係合片用孔２１と長係合片用孔２２とが対向して形成されており、前記長係合片用孔２２には長係合片１４の略半くさび形の先端が係合する立設片２３が設けられているものである。
【００２５】
そしてこの前板１８の取付片２０に操作ボタン１を取り付ける場合は、まず操作ボタン１を傾けて、短係合片用孔２１に操作ボタン１の短係合片１３を差し込んで短係合片１３の係合面１５を係合させ、次に操作ボタン１の傾いている方を押し上げるようにして、長係合片用孔２２に長係合片１４を差し込むと、長係合片１４先端の略半くさび形の部分が長係合片用孔２２の立設片２３と当接して押され、長係合片１４が内側に傾斜した状態となり、その状態で更に長係合片１４を差し込むと、立設片２３の先端が長係合片１４先端の略半くさび形の首部分に達した時、内側に傾斜した状態の長係合片１４が元の状態に戻って、長係合片１４の係合面１６と立設片２３の先端が係合するもので、これにより、操作ボタン１を取り付ける時は、立設片２３に長係合片１４先端が案内されてスムーズに取り付けることができ、操作ボタン１を強く押しても、取付片２０の立設片２３と長係合片１４先端のくさび形の部分との係合が外れないので、操作ボタン１を過度に操作しても操作ボタンが取付片２０から外れるのを防止できるものである。
【００２６】
又取付部本体１２の上面が前下がりで、係合面１５及び係合面１６も前下がりの傾斜がつけられているので、バネ部４の先端が取付片２０の下面に当接するような状態で取り付き、ボタン正面部７が常に前板１８の開口部１９に押しつけられるようになるものである。
【００２７】
そして前板１８に操作ボタン１を取り付けた状態で石油ストーブを組み立てた時、前板１８上部と接する接合部２４を先端部分を断面略コの字状に形成することにより形成した覆板２５が、前板１８上部に水平方向に設けられ、更にこの時、短係合片１３と長係合片１４との間隔よりも若干小さい幅の変形防止片２６が、短係合片１３と長係合片１４との間隔に位置して取付部３と重なるように、接合部２４に舌状に設けているものである。
【００２８】
次にこの操作ボタン１の動作について説明する。
図３の状態から指で操作ボタン１の凸部５を押すと、図４のようにバネ部４が前下がりのような状態で縮み、その時ボタン下部１１の作動片１０が点火ボタンなら点火装置に当接して点火動作させ、消火ボタンなら耐震自動消火装置のおもりに当接して倒して消火動作させるものである。
【００２９】
この時、この状態ですでに操作ボタン１には従来の操作ボタンを押すのに比べて強い力をかけている状態となって、操作ボタン１には強い反発力が発生しており、操作ボタン１を押している感触は従来よりも押しがいのあるものとなっており、従来の操作ボタンに比べて大きな力をバネ部４で吸収して取付片２０に力がかかるのを防止できるものである。
【００３０】
この状態から更に指で操作ボタン１を押した場合、バネ部４のＵ字状の開放部分が閉じて接する状態になり、それによりボタン上部７が取付部３を押し上げようとし、更にその取付部３が取付片２０を押し上げようとするが、取付片２０上面に重なっている変形防止片２６が、取付片２０が押し上がるのを防止し、それにより取付片２０が変形するのを防止できるものである。
【００３１】
又操作ボタン１が取付片２０から外れるためには、まず操作ボタン１が傾いて長係合片１４先端の略半くさび形の首部分が長係合片用孔２２の立設片２３からはずれないと操作ボタン１が取付片２０から外れないが、短係合片１３及び長係合片１４が内側に傾くのを変形防止片２６が規制するため、変形防止片２６が操作ボタン１が取付片２０から外れるのを防止しているものである。
【００３２】
そしてこの状態から操作ボタン１から指を離すと、押しつぶれることなくたわんでいるバネ部４に発生している強い反発力により、ボタン本体２は指で押す前の状態に戻り、更に取付部本体１２の上面は前下がりで約５度の傾斜がつけられていることからボタン正面部７が前板１８の開口部１９に押しつけられるような状態になるものである。
【００３３】
以上のように合成樹脂からなり、石油ストーブの前板１８の取付片２０に取り付けられる操作ボタン１に於いて、取り付けた時に前記前板１８の開口部１９に位置し、操作した時下方が石油ストーブ内の停止片６と当接するボタン正面部７と、該ボタン正面部７の上方に形成したボタン上部８と、前記ボタン正面部７の左右に形成したボタン側面部９と、操作した時に当接して石油ストーブを作動させる作動片１０を形成したボタン下部１１とからなる略箱状のボタン本体２と、前記取付片２０に形成した短係合片用孔２１に係合する短係合片１３と、取付片２０に形成した長係合片用孔２２に係合する長係合片１４と、前記短係合片１３と長係合片１４とを対向して立設した取付部本体１２からなる取付部３と、弾性を有し一端がボタン上部８の後端と一体に設けられ、他端が取付部本体１２前端と一体に設けられた略Ｕ字状のバネ部４とからなるので、操作ボタン１を操作した時、操作ボタン１にかかる押圧によりバネ部４がたわみ、押す力を強くしてもそれをバネ部４で蓄えて吸収し、操作ボタン１の操作を終了した時、バネ部４に蓄えられていた力により操作ボタン１を元の位置まで復旧させることができるものである。
【００３４】
又取付部本体１２上面からバネ部４にかけて前下がりに傾斜して形成すると共に、前記短係合片１３の係合面１５及び長係合片１４の係合面１６を前下がりに傾斜して形成したことにより、バネ部４の先端が取付片２０の下面に当接するような状態で取り付き、それによりバネ部４に押圧がかかった時の反発力を強めると共に、操作ボタン１を操作しない時も、前板１８の開口部１９に操作ボタン１が常に押しつけられるようになるものである。
【００３５】
又バネ部４はＵ字状の曲がり部分の厚さを薄くすると共に、ボタン上部８とバネ部４との間に補強部１７を形成したことにより、操作ボタン１を操作した時、操作ボタン１にかかる押圧によりバネ部４のＵ字状の開放部分が閉じると共に、Ｕ字状の先端部分が下がるようにしてたわむので、それにより操作ボタン１を押す力を強くしてもそれをバネ部４で蓄えて吸収することができ、更に補強部１７によりボタン上部８とバネ部４との間は押圧によりたわむ等の変形がなく、押圧が全てバネ部４にかかり、バネ部４が操作ボタン１を押す力をすべてが蓄えて吸収することができるもので、操作ボタン１の操作を終了した時、バネ部４に蓄えられていた力により操作ボタン１を元の位置まで復旧させることができるものである。
【００３６】
又前板１８の操作ボタン１を取り付ける取付片２０の上面に重なる舌状の変形防止片２６を、前板１８上部と接する覆板２５の接合部２４に形成したので、操作ボタン１を操作した時、操作ボタン１を押す力を強くして操作ボタン１が取付片２０を押し上げようとしても、取付片２０と重なっている変形防止片２６が、取付片２０が押し上がるのを防止し、それにより取付片２０が変形するのを防止できるものである。
【００３７】
又操作ボタン１上部に略Ｌ字状の短係合片１３と、先端が略くさび形の長係合片１４とを対向させて立設し、取付片２０には短係合片用孔２１と、長係合片１４の先端のくさび形の部分が係合する立設片２３を設けた長係合片用孔２２とを形成したので、操作ボタン１を強く押しても、取付片２０の立設片２３と長係合片１４先端のくさび形の部分との係合が容易に外れないので、操作ボタン１を過度に操作しても操作ボタン１が外れるのを防止できるものである。
【００３８】
又短係合片１３と長係合片１４との間隔よりも若干小さい幅の変形防止片２６を、短係合片１３と長係合片１４との間隔に位置するように設けたので、短係合片１３と長係合片１４とが外れる方向に動く、つまり内側に傾くのを変形防止片２６が規制するため、操作ボタン１をまっすぐ押すのではなく、操作ボタン１が外れるような斜めの方向に強く押しても、操作ボタン１が外れるのを防止できるものである。
【００３９】
【発明の効果】
以上のように請求項１の石油ストーブの操作ボタン取付構造によれば、前板の操作ボタンを取り付ける取付片の上面に重なる舌状の変形防止片を、前板上部と接する覆板の接合部に形成したので、操作ボタンを操作した時、操作ボタンを押す力を強くして操作ボタンが取付片を押し上げようとしても、取付片と重なっている変形防止片が、取付片が押し上がるのを防止し、それにより取付片が変形するのを防止できるものである。
【００４０】
又請求項２の石油ストーブの操作ボタン取付構造によれば、操作ボタン上部に略Ｌ字状の短係合片と、先端が略くさび形の長係合片とを対向させて立設し、取付片には短係合片用孔と、長係合片の先端のくさび形の部分が係合する立設片を設けた長係合片用孔とを形成したので、操作ボタンを強く押しても、取付片の立設片と長係合片先端のくさび形の部分との係合が容易に外れないので、操作ボタンを過度に操作しても操作ボタンが外れるのを防止できるものである。
【００４１】
又請求項３の石油ストーブの操作ボタン取付構造によれば、短係合片と長係合片との間隔よりも若干小さい幅の変形防止片を、短係合片と長係合片との間隔に位置するように設けたので、短係合片と長係合片とが外れる方向に動く、つまり内側に傾くのを変形防止片が規制するため、操作ボタンをまっすぐ押すのではなく、操作ボタンが外れるような斜めの方向に強く押しても、操作ボタンが外れるのを防止できるものである。

[0020]
【Example】
Next, an operation button according to the present invention will be described with reference to an embodiment shown in the drawings.
The description of the same components as in the conventional example will be omitted.
Reference numeral 1 denotes an operation button, which is made of a synthetic resin such as polypropylene, and is provided between the button body 2 and the mounting portion 3, a substantially box-shaped button body 2 having an open rear surface, an attachment portion 3 to which the operation button is attached. The spring portion 4 is formed in a U shape as viewed from the side and has strong elasticity.
[0021]
The button body 2 is formed with a convex portion 5 for pressing with a finger when operating, and when the convex portion 5 is pressed with a finger, the lower end of the button body 2 comes into contact with a stop piece 6 provided in the stove body. Part 7, button upper part 8 that is located at the upper part of button front part 7 and is integrated with one end of the U-shape of spring part 4, and button side part 9 provided at the left and right ends of button front part 7.

Is attached.
[0023]
The spring portion 4 has a U-shaped end portion having a thickness of about 1.5 mm, which is the same as the other portions of the operation button 1, whereas a U-shaped bent portion has a thickness of about 1 mm. Furthermore, since it is formed in a state in which the central portion is removed when viewed from the front, it has an appropriate elastic force while ensuring the strength of the spring portion 4, and can be prevented from being crushed even when pressed with a strong force. The reinforcing part 17 is formed in the upper part 8 of the button 2 and the lower part of the U-shape so that the lower part of the spring part 4 and the upper part 8 of the button are always parallel to each other. This is what is supposed to happen.
[0024]
Next, the mounting structure of the operation button 1 will be described.
18 is a front plate of a shin type radial oil stove, and the stove body of the oil stove includes a front plate 18, a bottom plate, a top plate, a side plate, a guard provided above the front plate, and a back plate. An opening 19 is formed on the front surface of the front plate 18 so that the convex portion 5 of the operation button 1 attached can be pushed with a finger, and a mounting piece 20 provided in a tongue shape at the bent portion of the upper portion of the front plate 18. Further, the short engagement piece hole 21 and the long engagement piece hole for inserting and engaging the short engagement piece 13 and the long engagement piece 14 of the operation button 1 in the attachment piece 20 are formed. The long engagement piece hole 22 is provided with a standing piece 23 with which the substantially half wedge-shaped tip of the long engagement piece 14 is engaged.
[0025]
When attaching the operation button 1 to the attachment piece 20 of the front plate 18, first, the operation button 1 is tilted, and the short engagement piece 13 of the operation button 1 is inserted into the short engagement piece hole 21 so that the short engagement piece is inserted. When the long engagement piece 14 is inserted into the long engagement piece hole 22 so as to engage the 13 engagement surfaces 15 and then push up the inclined side of the operation button 1, the tip of the long engagement piece 14 The substantially half wedge-shaped portion of the long engagement piece 14 is pressed against the standing piece 23 of the long engagement piece hole 22 so that the long engagement piece 14 is inclined inward. When inserted, when the tip of the standing piece 23 reaches the substantially half wedge-shaped neck portion of the tip of the long engagement piece 14, the long engagement piece 14 inclined inward returns to its original state, The engagement surface 16 of the joint piece 14 and the tip of the standing piece 23 are engaged, so that when the operation button 1 is attached, The distal end of the long engagement piece 14 can be smoothly mounted by being guided by the installation piece 23, and even if the operation button 1 is strongly pressed, the standing piece 23 of the attachment piece 20 and the wedge-shaped portion of the distal end of the long engagement piece 14 Therefore, even if the operation button 1 is excessively operated, it is possible to prevent the operation button from being detached from the attachment piece 20.
[0026]
Further, since the upper surface of the mounting portion main body 12 is forwardly lowered, and the engaging surface 15 and the engaging surface 16 are also inclined downwardly, the state where the tip of the spring portion 4 is in contact with the lower surface of the mounting piece 20 The button front portion 7 is always pressed against the opening 19 of the front plate 18.
[0027]
When the oil stove is assembled with the operation button 1 attached to the front plate 18, the cover plate 25 formed by forming the joint portion 24 in contact with the upper portion of the front plate 18 in a substantially U-shaped cross section is formed. Further, at this time, the deformation preventing piece 26 having a width slightly smaller than the distance between the short engagement piece 13 and the long engagement piece 14 is provided on the front plate 18 in the horizontal direction. The joint portion 24 is provided in a tongue shape so as to be positioned at a distance from the joint piece 14 and overlap the attachment portion 3.
[0028]
Next, the operation of the operation button 1 will be described.
When the convex portion 5 of the operation button 1 is pushed with a finger from the state of FIG. 3, the spring portion 4 is contracted in a state of being lowered forward as shown in FIG. The fire extinguishing button is placed in contact with the weight of the earthquake-proof automatic fire extinguishing device and brought down to fire.
[0029]
At this time, the operation button 1 is already applied with a stronger force than the conventional operation button is pressed, and the operation button 1 has a strong repulsive force. The feeling of pushing 1 is more depressing than the conventional one, and it is possible to prevent the mounting piece 20 from being forced by absorbing a larger force than the conventional operation button with the spring portion 4. .
[0030]
When the operation button 1 is further pressed with a finger from this state, the U-shaped open portion of the spring portion 4 is closed and comes into contact with it, whereby the button upper portion 7 tries to push up the attachment portion 3, and further the attachment portion 3 attempts to push up the mounting piece 20, but the deformation preventing piece 26 that overlaps the upper surface of the mounting piece 20 prevents the mounting piece 20 from being pushed up, thereby preventing the mounting piece 20 from being deformed. It is.
[0031]
In order for the operation button 1 to be detached from the mounting piece 20, first, the operation button 1 is inclined and the substantially half wedge-shaped neck portion at the tip of the long engagement piece 14 is disengaged from the standing piece 23 of the long engagement piece hole 22. Otherwise, the operation button 1 cannot be detached from the attachment piece 20, but the deformation prevention piece 26 restricts the inclining of the short engagement piece 13 and the long engagement piece 14, so that the deformation prevention piece 26 is attached to the operation button 1. This prevents the piece 20 from coming off.
[0032]
When the finger is released from the operation button 1 from this state, the button body 2 returns to the state before being pressed by the finger due to the strong repulsive force generated in the spring portion 4 that is bent without being crushed, and the attachment portion body. Since the upper surface of 12 is inclined downward by about 5 degrees, the button front portion 7 is pressed against the opening 19 of the front plate 18.
[0033]
As described above, the operation button 1 made of synthetic resin and attached to the attachment piece 20 of the front plate 18 of the oil stove is located in the opening 19 of the front plate 18 when attached, and when operated, the lower side is the petroleum oil. When the button front portion 7 is in contact with the stop piece 6 in the stove, the button upper portion 8 is formed above the button front portion 7, and the button side portions 9 are formed on the left and right sides of the button front portion 7. A substantially box-shaped button main body 2 comprising a button lower part 11 formed with an operating piece 10 that contacts and operates an oil stove, and a short engaging piece that engages with a short engaging piece hole 21 formed in the mounting piece 20. 13, a long engagement piece 14 that engages with a long engagement piece hole 22 formed in the attachment piece 20, and a mounting portion main body in which the short engagement piece 13 and the long engagement piece 14 are erected facing each other. 12 mounting part 3 and one end on the button with elasticity 8 is provided integrally with the rear end, and the other end is formed of a substantially U-shaped spring portion 4 provided integrally with the front end of the attachment portion main body 12. Therefore, when the operation button 1 is operated, the operation button 1 is applied. Even if the spring part 4 bends by pressing and the pushing force is increased, it is stored and absorbed by the spring part 4 and when the operation of the operation button 1 is finished, the operation button 1 is pushed by the force stored in the spring part 4. It can be restored to its original position.
[0034]
In addition, the mounting portion main body 12 is formed so as to be inclined downward from the upper surface to the spring portion 4, and the engagement surface 15 of the short engagement piece 13 and the engagement surface 16 of the long engagement piece 14 are inclined downward. By being formed, the spring portion 4 is attached in a state where the tip of the spring portion 4 is in contact with the lower surface of the mounting piece 20, thereby increasing the repulsive force when the spring portion 4 is pressed and not operating the operation button 1. Also, the operation button 1 is always pressed against the opening 19 of the front plate 18.
[0035]
Further, the spring portion 4 has a U-shaped bent portion with a reduced thickness, and a reinforcing portion 17 is formed between the button upper portion 8 and the spring portion 4, so that when the operation button 1 is operated, the operation button 1 Since the U-shaped open portion of the spring portion 4 is closed by the pressing applied to the spring portion and the U-shaped tip portion is bent so as to be lowered, the spring portion 4 can be bent even if the force of pushing the operation button 1 is increased thereby. In addition, the reinforcing portion 17 does not deform the button upper portion 8 and the spring portion 4 such that the button portion 8 is bent by pressing, and all the pressing is applied to the spring portion 4, and the spring portion 4 is operated by the operation button 1. All of the force that pushes can be stored and absorbed, and when the operation of the operation button 1 is finished, the operation button 1 can be restored to the original position by the force stored in the spring part 4 It is.
[0036]
Further, since the tongue-shaped deformation preventing piece 26 that overlaps the upper surface of the mounting piece 20 to which the operation button 1 of the front plate 18 is attached is formed at the joint portion 24 of the cover plate 25 that contacts the upper portion of the front plate 18, the operation button 1 is operated. Even when the operation button 1 tries to push up the mounting piece 20 by increasing the force to push the operating button 1, the deformation preventing piece 26 overlapping the mounting piece 20 prevents the mounting piece 20 from being pushed up. This prevents the mounting piece 20 from being deformed.
[0037]
Further, a short engagement piece 13 having a substantially L shape and a long engagement piece 14 having a substantially wedge-shaped tip are provided on the operation button 1 so as to face each other. And the long engagement piece hole 22 provided with the standing piece 23 with which the wedge-shaped portion at the tip of the long engagement piece 14 engages, even if the operation button 1 is strongly pressed, Since the engagement between the standing piece 23 and the wedge-shaped portion at the tip of the long engagement piece 14 cannot be easily disengaged, the operation button 1 can be prevented from coming off even if the operation button 1 is excessively operated.
[0038]
Further, since the deformation preventing piece 26 having a width slightly smaller than the interval between the short engagement piece 13 and the long engagement piece 14 is provided so as to be positioned at the interval between the short engagement piece 13 and the long engagement piece 14, Since the deformation preventing piece 26 restricts the short engagement piece 13 and the long engagement piece 14 from moving in a direction to be disengaged, that is, tilted inward, the operation button 1 may be released instead of pushing the operation button 1 straight. It is possible to prevent the operation button 1 from being detached even if the button is pressed strongly in an oblique direction.
[0039]
【The invention's effect】
As described above, according to the operation button mounting structure of the oil stove according to the first aspect, the tongue-shaped deformation preventing piece overlapping the upper surface of the mounting piece to which the operation button of the front plate is attached is joined to the cover plate in contact with the upper portion of the front plate. Therefore, when the operation button is operated, the force to push the operation button is strengthened, and even if the operation button tries to push up the mounting piece, the deformation preventing piece overlapping the mounting piece will push up the mounting piece. This can prevent the mounting piece from being deformed.
[0040]
Further, according to the operation button mounting structure of the oil stove according to claim 2, the short engagement piece having a substantially L shape and the long engagement piece having a substantially wedge shape at the front end are arranged to be opposed to each other on the operation button. The mounting piece is formed with a short engagement piece hole and a long engagement piece hole with a standing piece that engages the wedge-shaped part at the tip of the long engagement piece. In addition, since the engagement between the standing piece of the attachment piece and the wedge-shaped portion at the tip of the long engagement piece is not easily released, the operation button can be prevented from coming off even if the operation button is excessively operated. .
[0041]
According to the operation button mounting structure of the oil stove of claim 3, the deformation preventing piece having a width slightly smaller than the interval between the short engagement piece and the long engagement piece is provided between the short engagement piece and the long engagement piece. Because it is provided so as to be positioned at an interval, the deformation prevention piece restricts the movement of the short engagement piece and the long engagement piece in the direction of disengagement, that is, tilting inward. Even if the button is pushed strongly in an oblique direction so that the button is released, the operation button can be prevented from being released.
