【０００１】
【産業上の利用分野】
本発明は分割筐体の合わせ部への操作部材の取付構造およびこの取付構造を備える発音装置に関し、特に、２つに分割される筐体の合わせ部に、スライド式の操作ツマミ、あるいはプッシュ式の操作ボタンを取り付ける際の操作部材の取付構造およびこの取付構造を備える発音装置に関する。
【０００２】
【従来の技術】
従来、電子機器の筐体の外部には、押したり、スライドさせたりすることによって筐体内部に設けられた機器を動作させたり、調節したりする操作ボタンや操作ツマミが設けられている。このような操作ボタンや操作ツマミは一般に筐体の全面板に取り付けられることが多かった。
【０００３】
図７はこのような従来の電子機器の１つである電子チャイム７０の外観を示すものである。電子チャイム７０の前面カバー７１には、内蔵のスピーカからの音を出すための開口部７２がある。また、電子チャイム７０の前面カバー７１には、電子チャイム７０の音量を調節するための音量調節用ボリュームのツマミ７３、内蔵されたメロディを切り換えるためのメロディ切換用スイッチのツマミ７４、およびメロディ確認用モニターボタン７５等の操作部材が設けられていた。
【０００４】
ところが、以上のように構成された従来の電子チャイムでは、音量調節、メロディ切換、モニター等の操作ツマミや操作ボタンが電子チャイムのカバー前面側にあるので、電子チャイムが高所に取り付けられている場合の操作性が悪く、また、操作ツマミや操作ボタンの位置が下から確認しづらいという問題があった。これは高所に取り付けられる電子機器における一般的な課題であった。
【０００５】
そこで、本出願人は、高所に取り付けられる電子機器、例えば電子チャイムのような発音装置において、その筐体を、壁面等の造営材に取り付けられる下部筐体と、この下部筐体に重ね合わされる上部筐体とに分割して形成し、その下部筐体内に、発音用のスピーカと、このスピーカの駆動回路と、この駆動回路への信号の授受を行う端子と、前記スピーカの音色調整、音量調整等の制御を行う駆動回路の制御部とを設け、制御部は下部筐体の造営材への取り付け状態における下部に位置させ、上部筐体と下部筐体の合わせ部にこの制御部の操作部材を配置したものを既に提案した。
【０００６】
図６は本出願人が既に提案した発音装置の外観を示すものであり、ここでは発音装置として電子チャイム１０を例にとってその構成を説明する。本出願人の提案した電子チャイム１０は、壁面等の造営材に取り付けられる下部筐体１１と、この下部筐体１１に重ね合わされる上部筐体１２とを備えており、上部筐体１２の内部に音を発生させるスピーカが設けられている。このスピーカに重なる部分の上部筐体１２はドーム状に膨出されており、この膨出部１３には内蔵のスピーカ１からの音を出すための開口部は設けられておらず、スピーカ１からの音は膨出部１３の裾部１３ａに設けられた開口１３ｂから出るようになっている。
【０００７】
また、電子チャイム１０の下側の側面の下部筐体１１と上部筐体１２との合わせ部１には、操作部材として、電子チャイム１０の音量を調節するための音量調節用ボリュームの操作ツマミ２、内蔵されたメロディを切り換えるためのメロディ切換用スイッチの操作ツマミ３、およびメロディ確認用モニターボタン４が設けられている。このうち、節用ボリュームの操作ツマミ２とメロディ切換用スイッチの操作ツマミ３とはスライド式であり、メロディ確認用モニターボタン４はプッシュ式である。
【０００８】
【発明が解決しようとする課題】
しかしながら、図６に示したように上部筐体と下部筐体とからなる電子チャイムの合わせ部に操作ツマミや操作ボタンを配置する場合には、単にこれらを合わせ部に挟み込んだだけでは、下部筐体から上部筐体を取り外した時に、各操作ツマミや操作ボタンが外れやすいという問題点がある。
【０００９】
そこで、本発明は、２分割される筐体の合わせ部に操作部材を設ける電子機器において、操作部材の取り付け作業性が良く、また、筐体を分割した際にも操作部材が筐体から容易に外れることがない、分割筐体の合わせ部への操作部材の取付構造およびこの取付構造を備える発音装置の提供を目的としている。
【００１０】
【課題を解決するための手段】
前記目的を達成する本発明の第１の形態の分割筐体の合わせ部への操作部材の取付構造は、第１の筐体と第２の筐体の２つに分割される筐体の合わせ部に、筐体に内蔵される機器をスライド操作する操作ツマミを取り付ける構造であって、前記第１の筐体と第２の筐体には、その合わせ部の両方、あるいは何れか一方に前記操作ツマミの首部を挿通するための凹部を設ける一方、前記第１の筐体と第２の筐体の何れか一方の筐体の内部側に、筐体外壁と平行な内壁を、この外壁と所定の間隙を隔てて設けるとともに、外壁または内壁の何れか一方の下部に段部を設け、前記操作ツマミには、前記２つの筐体の合わせ部の外側に露出する操作頭部と、前記凹部を挿通して前記筐体内部側に延びる前記操作頭部の首部と、この首部に連続する胴部とを設け、この胴部には、前記間隙内に挿入可能な２枚の平行な第１、第２のガイド板と、前記第２のガイド板に平行でその間に前記内壁が挿入可能な第３のガイド板と、前記内壁の内側に位置する前記機器の操作軸に係合する係合部とを設けると共に、この第１、第２のガイド板の何れか１枚の先端部には係止突起を設け、前記外壁と内壁の間の間隙内に前記第１と第２のガイド板のうち係止突起を設けたガイド板が係止突起を設けられていないガイド板側に撓むように前記第１と第２のガイド板を挿入し、前記第２と第３のガイド板の間に前記内壁を挿入し、前記操作軸に前記係合部を係合して前記首部を前記凹部内に位置させると、前記係止突起によりこの操作ツマミが前記外壁または内壁の何れか一方の段部に係止され、前記操作ツマミが前記凹部内をスライド可能に前記第１の筐体と第２の筐体の合わせ部に取り付けられることを特徴としている。
【００１１】
また、目的を達成する本発明の第２の形態の分割筐体の合わせ部への操作部材の取付構造は、第１の筐体と第２の筐体の２つに分割される筐体の合わせ部に、筐体に内蔵される機器を操作する操作ボタンを取り付ける構造であって、前記第１の筐体と第２の筐体には、その合わせ部の両方に前記操作ボタンの頭部を挿通するための凹部を設ける一方、前記第１の筐体と第２の筐体の何れか一方の筐体の内部側に、筐体外壁と平行な内壁を、この外壁と所定の間隙を隔てて設けるとともに、外壁の下部に段部を設け、前記操作ボタンには、前記２つの筐体の合わせ部の外側に露出する前記操作頭部と、この操作頭部に連続する胴部とを設け、この胴部には、前記内壁の内側に位置する前記機器の操作軸に当接する当接部と、前記操作ボタンの前記筐体への取付状態で、前記外壁の内面に隣接する第１のガイド板、および、この第１のガイド板に平行でかつ前記内壁の内面に隣接する第２のガイド板とを設け、この第１のガイド板の先端部には係止突起を設けると共に、前記第１のガイド板の内面には、前記操作ボタンの前記筐体への取付状態で前記内壁の外面を付勢する伸縮部材を設け、前記外壁と内壁の間の間隙内に前記伸縮部材を筐体の内壁側に押し付けながら前記第１のガイド板と前記伸縮部材を挿入し、前記伸縮部材と第２のガイド板の間に前記内壁を挿入し、前記操作軸に前記当接部を当接しない状態で前記頭部を前記凹部内に位置させると、前記係止突起によりこの操作ボタンが前記外壁の段部に係止され、前記操作ボタンの頭部の押圧により、前記操作ボタンが前記伸縮部材を付勢して前記筐体内部側に没入可能に前記第１の筐体と第２の筐体の合わせ部に取り付けられることを特徴としている。
【００１２】
なお、前記第１、第２の形態の分割筐体の合わせ部への操作部材の取付構造は、壁面等の造営材に取り付けられる下部筐体と、この下部筐体に重ね合わされる上部筐体とを備え、これら上部筐体と下部筐体とからなる筐体内部に、発音用のスピーカと、このスピーカの駆動回路と、この駆動回路への信号の授受を行う端子と、前記スピーカの音色調整、音量調整等の制御を行う前記駆動回路の制御部とが設けられ、前記制御部は前記下部筐体の前記造営材への取り付け状態における下部に位置し、この制御部に設けられたスライド式の操作機器の操作ツマミおよびプッシュ式の操作機器の操作ボタンが、前記上部筐体と前記下部筐体の下面側の合わせ部に露出するように設けられた発音装置において、この操作ツマミまたは操作ボタンの前記上部筐体と前記下部筐体の合わせ部への取付構造として、前記発音装置に有効に適用することができる。
【００１３】
【作用】
本発明の第１の形態の分割筐体の合わせ部への操作部材の取付構造によれば、操作部材を取り付ける側の筐体外壁と内壁の間の間隙内に、操作ツマミの胴部に突設された第１と第２のガイド板を挿入していくと、第２と第３のガイド板の間に内壁が挿入され、ボリュームやスイッチの操作軸に操作ツマミの胴部の係合部を係合して首部を筐体外壁に設けた凹部内に位置させると、第１から第３のガイド板の何れかの先端に設けられた係止突起によりこの操作ツマミが筐体外壁または内壁の何れか一方に係止され、操作ツマミが筐体凹部内をスライド可能に第１の筐体と第２の筐体の合わせ部に取り付けられる。
【００１４】
本発明の第２の形態の分割筐体の合わせ部への操作部材の取付構造によれば、操作部材を取り付ける側の筐体外壁と内壁の間の間隙内に、操作ボタンの胴部に突設された第１のガイド板とこの第１のガイド板上に設けられた伸縮部材を挿入していくと、この伸縮部材と第２のガイド板の間に筐体内壁が挿入され、ボリュームやスイッチの操作軸に操作ボタンの胴部の係合部を係合して頭部を筐体筐体外壁に設けた凹部内に位置させると、第１または第２のガイド板の何れかの先端に設けられた係止突起によりこの操作ボタンが筐体外壁または内壁の何れか一方に係止され、操作ボタンの頭部の付勢により、操作ボタンが伸縮部材を付勢して筐体内部側に没入可能に第１の筐体と第２の筐体の合わせ部に取り付けられる。
【００１５】
【実施例】
以下添付図面を用いて本発明の実施例を詳細に説明する。
【００１６】
図１（ａ）は本発明の一実施例の発音装置の構成を示す一部切欠斜視図であり、図１（ｂ）はこの発音装置を取付状態の下面から見た側面図である。ここでは発音として電子チャイム１０を例にとってその構成を説明する。ここで説明する電子チャイム１０も従来のものと同様に、押しボタンを押すことによって複数の信号音、例えば、『ピンポン』や『ピッ、ピッ、ピッ』を発生することができると共に、複数種類のメロディを流すことができるものとする。
【００１７】
この実施例の電子チャイム１０は、壁面等の造営材に取り付けられる下部筐体１１と、この下部筐体１１に重ね合わされる上部筐体１２とを備えており、上部筐体１２の内部に音を発生させるためのスピーカ（図示せず）が設けられている。このスピーカに重なる部分の上部筐体１２はドーム状に膨出されており、この膨出部１３には内蔵のスピーカからの音を出すための開口部は設けられておらず、スピーカ１からの音は膨出部１３の裾部１３ａに設けられた開口１３ｂから出るようになっている。また、電子チャイム１０の下側の側面の下部筐体１１と上部筐体１２の合わせ部１には、電子チャイム１０の音量を調節するための音量調節用ボリュームのツマミ２、内蔵されたメロディを切り換えるためのメロディ切換用スイッチのツマミ３、およびメロディ確認用モニターボタン４等の操作部材（調整部材）が設けられている。
【００１８】
図１（ｂ）に示すように、下部筐体１１と上部筐体１２には、その合わせ部１に音量調節用ボリュームのツマミ２とメロディ切換用スイッチのツマミ３、およびモニターボタン４を挿通するための凹部１１ａ〜１１ｃと凹部１２ａ〜１２ｃが設けられいる。一方、下部筐体１１にはその外壁１１ｏの内部側に内壁１１ｉが設けられており、この内壁１１ｉの音量調節用ボリュームのツマミ２、メロディ切換用スイッチのツマミ３、およびモニターボタン４が取り付けられる部位は、図１（ａ）に示すように切り欠かれており、内壁１１ｉが外壁１１ｏに対して所定の間隙Ｋを隔てて平行になっている。
【００１９】
図２（ａ）〜（ｃ）は図１の電子チャイム１０に取り付けられる音量調節用ボリュームのツマミ２、メロディ切換用スイッチのツマミ３、およびモニターボタン４のの一実施例の構成を示すものである。
【００２０】
図２（ａ）に示す音量調節用ボリュームのツマミ２には、下部筐体１１と上部筐体１２の合わせ部１の外側に露出する操作頭部２ａと、合わせ部１を挿通して筐体内部側に延びる首部２ｂと、この首部２ｂに連続する胴部２ｃが設けられている。胴部２ｃの下面には３枚の平行なガイド板２１，２２，２３が突設されており、ガイド板２１，２２は図１（ａ）に示した内壁１１ｉと外壁１１ｏの間の間隙Ｋ内に挿入可能に隔てられ、ガイド板２３はガイド板２２との間に内壁１１ｉが挿入可能にガイド板２２から隔てられている。また、この実施例ではガイド板２１の先端部に、音量調節用ボリュームのツマミ２を下部筐体１１の外壁１１ｏに取り付けた時に、外壁１１ｏの端部に係合して音量調節用ボリュームのツマミ２を下部筐体１１から外れなくするための係止突起２４が設けられている。更に、胴部２ｃの内壁１１ｉの内側に位置する部分には、筐体内部に設けられた音量調節用ボリュームの操作軸２Ａに係合する係合凹部２５が設けられている。
【００２１】
図２（ｂ）に示すメロディ切換用スイッチのツマミ３には、下部筐体１１と上部筐体１２の合わせ部１の外側に露出する操作頭部２ａと、合わせ部１を挿通して筐体内部側に延びる首部３ｂと、この首部３ｂに連続する胴部３ｃが設けられている。胴部３ｃの下面には３枚の平行なガイド板３１，３２，３３が突設されており、ガイド板３１，３２は音量調節用ボリュームのツマミ２と同様に内壁１１ｉと外壁１１ｏの間の間隙Ｋ内に挿入可能に隔てられ、ガイド板３３はガイド板３２との間に内壁１１ｉが挿入可能にガイド板３２から隔てられている。また、この実施例ではガイド板３１の先端部に、メロディ切換用スイッチのツマミ３を下部筐体１１の外壁１１ｏに取り付けた時に、外壁１１ｏの端部に係合してメロディ切換用スイッチのツマミ３を下部筐体１１から外れなくするための係止突起３４が設けられている。更に、胴部３ｃの内壁１１ｉの内側に位置する部分には、筐体内部に設けられたメロディ切換用スイッチの操作軸３Ａに係合する係合凹部３５が設けられている。
【００２２】
図２（ｃ）に示すモニターボタン４には、下部筐体１１と上部筐体１２の合わせ部１の外側に露出する操作頭部４ａと、この操作頭部４ａに連続する胴部４ｂとが設けられており、操作頭部４ａが下部筐体１１と上部筐体１２の合わせ部１を挿通するようになっている。胴部４ｂの下面には２枚の平行なガイド板４１，４２が突設されており、ガイド板４１は音量調節用ボリュームのツマミ２と同様に内壁１１ｉと外壁１１ｏの間の間隙Ｋ内に挿入可能な位置にある。ガイド板４１のガイド板４２に対向する面には、伸縮部材であるスポンジ４３が設けられており、ガイド板４１はこのスポンジ４３を圧縮しながら内壁１１ｉと外壁１１ｏの間の間隙Ｋ内に挿入される。一方、ガイド板４２は、スポンジ４３が適度に圧縮されてガイド板４１と共に内壁１１ｉと外壁１１ｏの間の間隙Ｋ内に挿入される時に、内壁１１ｉの内側に当接するようにガイド板４１から隔てられている。また、この実施例ではガイド板４１の先端部に、モニターボタン４を下部筐体１１の外壁１１ｏに取り付けた時に、外壁１１ｏの端部に係合してモニターボタン４を下部筐体１１から外れなくするための係止突起４４が設けられている。更に、内壁１１ｉの内側に位置する胴部４ｂの側面４５は、モニタースイッチの操作軸４Ａに当接する当接部として構成される。但し、モニターボタン４が合わせ部１に取り付けられた状態で、操作頭部４ａが押圧されないときは、筐体内部に設けられたモニタースイッチの操作軸４Ａには当接しないようになっている。
【００２３】
ここで、以上のように構成された音量調節用ボリュームのツマミ２、メロディ切換用スイッチのツマミ３、およびモニターボタン４の下部筐体１１と上部筐体１２との合わせ部１への取り付けを、音量調節用ボリュームのツマミ２を例にとって図３を用いて説明する。
【００２４】
図３（ａ）は図１に示した電子チャイム１０の上部筐体１２を取り外した状態の下部筐体１１に音量調節用ボリュームのツマミ２を取り付ける状態を示すものである。下部筐体１１の中には基板１１Ａがあり、この基板１１Ａの上に音量調節用ボリューム２Ｂが取り付けられている。音量調節用ボリュームのツマミ２を合わせ部１に取り付ける時には、外壁１１ｏと内壁１１ｉの間の間隙Ｋ内にガイド板２１、２２を挿入していくと、ガイド板２２、２３の間に内壁１１ｉが挿入される。このとき、ガイド板２１の先端部には係止突起２４があるので、ガイド板２１はガイド板２２側に撓みながら間隙Ｋの中に挿入される。音量調節用ボリューム２Ｂの操作軸２Ａに係合部２５を係合させて首部２ｂを凹部１１ａ内に位置させた状態では、係止突起２４が外壁１１の下部に設けられた段部１１ｄに係合し、音量調節用ボリュームのツマミ２が外壁１１ｏから外れなくなる。
【００２５】
図３（ｂ）は以上のようにして音量調節用ボリュームのツマミ２を下部筐体１１の合わせ部１に取り付け、その上に上部筐体１２を取り付けた状態を示すものである。この状態では、上部筐体１２の合わせ部の凹部１２ａが音量調節用ボリュームのツマミ２の首部２ｂに重なり、音量調節用ボリュームのツマミ２は凹部１１ａと１２ａからなる空間内をスライド可能に下部筐体１１と上部筐体１２の合わせ部１に取り付けられる。
【００２６】
なお、音量調節用ボリュームのツマミ２を下部筐体１１から取り外す時は、下部筐体１１の下方からピン等で係止突起２４をガイド板２２側に撓ませ、係止突起２４の段部１１ｄとの係合を外せば、音量調節用ボリュームのツマミ２は容易に下部筐体１１から取り外せる。
【００２７】
図４は同様の方法でメロディ切換用スイッチのツマミ３を下部筐体１１と上部筐体１２の合わせ部１に取り付けた状態を示すものである。図において、３Ｂは基板１１Ａの上に取り付けられたメロディ切換用スイッチ、５はスピーカである。メロディ切換用スイッチのツマミ３を合わせ部１に取り付ける時は、音量調節用ボリュームのツマミ２と同様にすれば良く、間隙Ｋ内にガイド板３１、３２を挿入していくと、ガイド板３２、３３の間に内壁１１ｉが挿入される。また、メロディ切換用スイッチ３Ｂの操作軸３Ａに係合部３５を係合させて首部３ｂを凹部１１ｂ内に位置させた状態では、係止突起３４が外壁１１の下部に設けられた段部１１ｄに係合し、メロディ切換用スイッチのツマミ３が外壁１１ｏから外れなくなる。そして、上部筐体１２の取付状態状態では、上部筐体１２の合わせ部の凹部１２ａがメロディ切換用スイッチのツマミ３の首部３ｂに重なり、メロディ切換用スイッチのツマミ３は凹部１１ｂと１２ｂからなる空間内をスライド可能に下部筐体１１と上部筐体１２の合わせ部１に取り付けられる。メロディ切換用スイッチのツマミ３を下部筐体１１から取り外す時も音量調節用ボリュームのツマミ２と同様にすれば良い。
【００２８】
図５は同様の方法でモニターボタン４を下部筐体１１と上部筐体１２の合わせ部１に取り付けた状態を示すものである。図において、４Ｂは基板１１Ａの上に取り付けられたモニタースイッチである。モニターボタン４を合わせ部１に取り付ける時は、前述の音量調節用ボリュームのツマミ２とメロディ切換用スイッチのツマミ３の取り付けと異なり、ガイド板４１の上に設けられたスポンジ４３を内壁１１ｉに軽く押し付けながら間隙Ｋ内にガイド板４１を挿入し、内壁１１ｉの内側にガイド板４２を沿わせて挿入する。また、モニターボタン４の頭部４ａを凹部１１ｃ内に位置させた状態では、係止突起４４が外壁１１の下部に設けられた段部１１ｄに係合し、モニターボタン４が外壁１１ｏから外れなくなる。このモニターボタン４の合わせ部１への取付状態では、内壁１１ｉの内側に位置する胴部４ｂの側面４５は、筐体内部に設けられたモニタースイッチ４Ｂの操作軸４Ａには当接しない。そして、上部筐体１２の取付状態状態では、上部筐体１２の合わせ部の凹部１２ａがモニターボタン４の頭部４ａに重なり、モニターボタン４は凹部１１ｃと１２ｃからなる空間内を、ズポンジ４３を圧縮しながら内部方向にスライド可能に下部筐体１１と上部筐体１２の合わせ部１に取り付けられる。モニターボタン４を下部筐体１１から取り外す時は音量調節用ボリュームのツマミ２と同様にすれば良い。
【００２９】
この実施例の電子チャイム１０では、操作部材である音量調節用ボリュームのツマミ２、メロディ切換用スイッチのツマミ３、およびメロディ確認用モニターボタン４の頭部２ａ，３ａ，４ａは、図１（ｂ）に示すように、下部筐体１１の下側の側面に露出している。そして、この実施例では、下部筐体１１の下側の側面が本体側に窪まされて凹部１４が形成され、この下部筐体１１に重ね合わされる上部筐体１２のこの凹部１４の対向部分にも同様の凹部１５が形成されている。そして、メロディ切換用スイッチのツマミ３、およびメロディ確認用モニターボタン４の頭部２ａ，３ａ，４ａはこの凹部１４，１５の中に位置している。
【００３０】
また、下部筐体１１と上部筐体１２の下側の合わせ面に設けられる凹部１４，１５の全長は、メロディ切換用スイッチのツマミ３、およびメロディ確認用モニターボタン４の頭部２ａ，３ａ，４ａが設けられる範囲よりも長くなっており、この凹部１４，１５内に人の指が挿入できる程度以上の長さの空間が確保されている。この結果、下部筐体１１から上部筐体１２を取り外す時に、図１（ｂ）に二点鎖線で示すように、人が指Ｆをこの凹部１４，１５に差し入れて上部筐体１２を引き上げることにより、下部筐体１１から上部筐体１２を簡単に取り外すことができる。
【００３１】
なお、以上説明した実施例では２つに分割できる筐体を持つ機器として、発音装置である電子チャイムを例にとって説明したが、本発明の分割筐体の合わせ部への操作部材の取付構造は、２つに分割できる筐体を持つ機器の合わせ部に操作部材を取り付ける場合に有効に適用することが可能である。
【００３２】
【発明の効果】
以上説明したように、本発明によれば、２つに分割される筐体の合わせ部に操作部材を設ける電子機器、特に、電子チャイムのような発音装置において、操作部材の取り付け作業性が良く、また、筐体を分割した際にも操作部材が筐体から容易に外れることがないという効果がある。
