Description

【０００１】
【発明の属する技術分野】
本発明は、電子機器を制御盤のパネル等の他部材に取付ける取付け構造及び当該取付けに使用する装置に関するものである。本発明は、操作部や表示部が前面側に有り、縦横の寸法が異なる角型の電子機器を、制御盤のパネル部材に取付ける場合に特に好適である。
【０００２】
【従来の技術】
各種の生産設備や実験設備には、圧力センサ、温度センサー、画像センサ、温度調節器、プログラマブルコントローラ、切り替え装置、タッチパネルディスプレイ、カウンター、タイマーその他の電子機器が多用されている。
またこれらの電子機器には、筐体内にＩＣ等の素子が内蔵され、前面の露出部分にディスプレイ等の表示部やスイッチ等の操作部が設けられたものがある。
上記した様な前面の露出部分に表示部や操作部が設けられた電子機器を制御盤のパネルに組み込む場合は、表示部や操作部が制御盤の前面に露出する様に取付けられる場合が多い。
【０００３】
旧来、これらの電子機器の取付けは、ビスを使用する方策が広く採用されていたが、取付けの手間を省く目的から、電子機器等に取付け爪を設け、当該取付け爪を制御盤の開口等に係合させる構造が採用されるようになった。
またさらに、電子機器の後端側に別途成形された電子機器取付け装置を装着して電子機器を制御盤等に取付ける構成も知られている（例えば特許文献１参照）。
特許文献１には、制御盤等のパネルの開口部に対して、同一サイズの電子機器を複数取りつける際に用いる取付け装置の開示がある。
【０００４】
【特許文献１】
特開平２００２−１６３７７号公報
【０００５】
図２７は、上記した特許文献に添付された図面である。特許文献に開示された構造は、電子機器１００をパネル１０１の開口に挿入すると共に、電子機器１００の後端側に電子機器取付け装置１０２を装着し、電子機器１００の前端部分と電子機器取付け装置１０２との間で開口の縁を挟み込み、電子機器１００をパネル１０１に取付けるものである。
上記した特許文献１に記載された電子機器取付け装置１０２は、図２７に示すように長方形の枠状本体１０３を持ち、その長手方向両端に張出部分１０５，１０６がある。当該枠状本体１０３には、係合爪１０７が設けられており、この係合爪１０７は電子機器１００に取付けられたギザ状の凹凸１０８と係合する。また前記した張出部分には、ビス１１０が設けられている。
【０００６】
従来技術の電子機器の取付け構造では、前記した様に、電子機器１００をパネル１０１の開口に挿入すると共に、電子機器１００の後端側に電子機器取付け装置１０２を装着する。装着状態においては、電子機器取付け装置１０２側の係合爪１０７と電子機器１００側のギザ状凹凸１０８が係合し、電子機器取付け装置１０２の電子機器後端側への移動が阻止される。
そして張出部分１０５，１０６に設けられたビス１１０を締め込んで、ビス１１０をパネル１０１に押し当て、電子機器取付け装置１０２を電子機器１００の後端側へ付勢し、電子機器取付け装置側の係合爪１０７と電子機器側のギザ状凹凸１０８との遊びを無くす。その結果、電子機器１００がパネル１０１に取付けられる。
【０００７】
上記した従来技術の取付け構造では、電子機器取付け装置１０２の長手方向両端に設けられた張出部分１０５，１０６に設けられるビス１１０が、パネル１０１の開口の縁に当接し、電子機器１００の前端部分との間で開口の縁を挟み込み、電子機器１００をパネル１０１に固定している。
図２７の姿勢に基づいて説明すると、略長方形の枠たる電子機器取付け装置１０２の左右両端のビス１１０がが、パネル１０１の開口の左右側の縁、すなわち縦方向の縁に当接して電子機器１００の前端部分との間で開口の縁を挟み込み、電子機器１００をパネル１０１に固定している。
【０００８】
【発明が解決しようとする課題】
ところで、電子機器のパネルへの取付けパターンとして、１つの角孔に一つの電子機器を取付ける場合（単体取付）、縦方向の長孔に複数個の電子機器を並べて取付ける場合（縦方向複数取付）および横方向の長孔に複数個の電子機器を並べて取付ける場合（横方向複数取付）が考えられる。
ここで１つの角孔に一つの電子機器を取付けられる場合（単体取付）は、電子機器取付け装置の４辺の内の２辺、すなわち上下または左右の辺のいずれか又は双方をパネルの開口の上下又は左右の縁に当接して固定することができる。
【０００９】
これに対して縦方向複数取付および横方向複数取付けを行う場合には、電子機器取付け装置を当接する位置に制約を受ける。
すなわち電子機器を縦方向複数取付する場合には、電子機器取付け装置の左右の辺をパネルの開口の左右の縁（長手の辺）に当接しなければならない。この点、特許文献に開示された電子機器取付け装置１０２は、左右両端の垂直壁部分（張出部分１０５，１０６）に設けられたビス１１０をパネル１０１の開口の左右の縁（長手の辺の縁）に当接させることができるので、電子機器１００を縦方向に複数取付けるには適している。
しかし逆に電子機器を横方向複数取付する場合には、電子機器取付け装置の上下の辺をパネルの開口の上下の縁に当接しなければならない。
しかしながら、上記した特許文献に示された電子機器取付け装置１０２は、左右両端の垂直壁部分（張出部分１０５，１０６）に設けられたビス１１０だけがパネル１０１に当接し得る構造であるから、上下の部分にはパネル１０１に当たるべき当たりしろが無い。そのため特許文献に示された電子機器取付け装置１０２をもってしては、電子機器を横方向に並べて複数取付けることができない。
【００１０】
さらに加えて、従来技術の電子機器取付け装置１０２は、縦方向に複数の電子機器１００を積み重ねる場合、個々の機器のパネル１０１に対する取付けと、重なり合う機器間の位置決めについては有効なものの、横方向一列に機器を並べようとした場合、個々の機器を取りつける金具（装置）に設けられる位置決め部（張出部分１０５，１０６）が干渉し、最小のスペースで電子機器１００を制御盤のパネル１０１等に取りつけることができないという問題もあった。
【００１１】
そのため従来技術によると、縦方向に並べて取付ける場合に使用する装置と、横方向に並べて取付ける場合に使用する装置の二種類を用意しなければ、任意の配置パターンに対応することができず、部品の互換性が低いという問題があった。
またそもそも、複数の機器を制御盤のパネル１０１等に対してどのようなレイアウトで配列するかは、機器を使用するユーザの要望やパネル１０１そのものの制限によって決まる為、最小のスペースを提供しつつ、縦・横のいずれの方向に対しても取付け可能であり、レイアウト自由度の高い取付構造が望まれる。
本発明は、従来技術の上記した問題点に注目し、取付レイアウトの自由度が高い電子機器の取付け構造及びこれに使用する装置を提供することを課題とするものである。
また本発明は、従来技術の上記した問題点に注目し、電子機器の縦横両方向への複数取付けを、単一構造の取付け装置を使用して行うことができる電子機器の取付け構造及びこれに使用する装置を提供することを課題とするものである。
【００１２】
【課題を解決するための手段】
そして上記した課題を解決するための請求項１に記載の発明は、電子機器の後端側をパネル部材に設けられた開口に挿入し、電子機器の後端側に電子機器取付け装置を装着し、電子機器取付け装置の一部をパネル部材に当接させて電子機器をパネル部材に取付ける電子機器取付け構造において、電子機器取付け装置は、枠状であって前後方向が連通開口する本体部を有し、電子機器取付け装置は、本体部の一方の開口を先頭にして電子機器の後端側に装着される正方向装着と、本体部を裏返して他方の開口を先頭にして電子機器の後端側に装着される逆方向装着が可能であり、正方向装着における装着状態と逆方向装着における装着状態は、パネル部材に対する当接状態が異なることを特徴とする電子機器取付け構造である。
【００１３】
ここで本体部の「前後方向」や、「正方向」「逆方向」の文言は、相対的な位置関係や方向を意味する表現に過ぎず、いずれの取付け方向が正であるとか逆であるとかを限定するものではない。以下の請求項についても同様である。
本発明の電子機器取付け構造は、電子機器取付け装置を使用するものであり、従来技術と同様に電子機器の後端側をパネル部材に設けられた開口に挿入し、電子機器の後端側に電子機器取付け装置を装着して電子機器を固定する。
【００１４】
本発明で使用する電子機器取付け装置は、枠状であって前後方向が連通開口する本体部を備える。そして本発明で採用する電子機器取付け装置は、本体部の一方の開口を先頭にして電子機器の後端側に装着される正方向装着と、本体部を裏返して他方の開口を先頭にして電子機器の後端側に装着される逆方向装着が可能である。要するに本発明で使用する電子機器取付け装置は、正規方向の取付けの他に逆向けの取付けが可能であり、二通りに取付けることができる。そして本発明の電子機器取付け構造では、正方向装着における装着状態と逆方向装着における装着状態は、パネル部材に対する当接状態が異なる。なお電子機器の後端側を挿入する「パネル部材」と電子機器取付け装置が当接する「パネル部材」は必ずしも同一物でなくてもよい。この点については以下の請求項についても同様である。
【００１５】
「パネル部材に対する当接状態が異なる」とは例えばパネル部材と当接する位置が異なる場合や、パネル部材を押圧する力加減、あるいは押圧力の分布が異なる様な状況を表している。
パネル部材と当接する位置が異なる場合とは例えば次の様な場合である。すなわちパネル部材に四角の開口があると仮定したとき、開口の辺を時計回りにＡ辺（例えば上辺）、Ｂ辺（例えば右縦辺）、Ｃ辺（例えば下辺）、Ｄ辺（例えば左縦辺）とすると、正方向装着における装着状態では、電子機器取付け装置は開口のＡ辺（例えば上辺）とＣ辺（例えば下辺）に当接し、他の辺とは当接しない。一方、逆方向装着における装着状態では、開口のＢ辺（例えば右縦辺）、Ｄ辺（例えば左縦辺）と当接し、他の辺とは当接しない。
【００１６】
また押圧力の分布が異なる例としては、正方向装着においても逆方向装着においてもＡ，Ｂ，Ｃ，Ｄの４辺全てと接するが、正方向装着の場合には特に上下のＡ，Ｃ辺を強く押圧し、逆方向装着の場合には左右縦辺たるＢ，Ｄ辺を強く押圧する構成が考えられる。
【００１７】
さらに正方向装着においても逆方向装着においてもＡ，Ｂ，Ｃ，Ｄの４辺全てと接するが、正方向装着の場合には特に上下のＡ，Ｃ辺に対する接触面積が大きく、逆方向装着の場合には左右の縦辺たるＢ，Ｄ辺に対する接触面積が大きい様な構成も採用可能である。
本発明の電子機器取付け構造は、正方向装着による場合と、逆方向装着による場合でパネル部材に対する当接状態が異なるので、電子機器を実質的に支持するパネル部材の被押圧部を変更することができる。そのため本発明の電子機器取付け構造は、取付レイアウトの自由度が高い。
【００１８】
また請求項２に記載の発明は、電子機器の後端側をパネル部材に設けられた開口に挿入し、電子機器の後端側に電子機器取付け装置を装着し、電子機器取付け装置の一部をパネル部材に当接させて電子機器をパネル部材に取付ける電子機器取付け構造において、電子機器の筐体に複数の機器側係合部が設けられ、電子機器取付け装置は、枠状であって前後方向が前記電子機器の筐体を挿入可能に連通開口する本体部と、第一方向用係合部及び第二方向用係合部とを有し、電子機器取付け装置は、前記本体部の一方の開口を先頭にして、電子機器の前記複数の機器側係合部の少なくとも一部と電子機器取付け装置の前記第一方向用係合部が係合し、電子機器の後端側に装着される正方向装着と、前記本体部を裏返して他方の開口を先頭にして、電子機器の前記複数の機器側係合部の少なくとも一部と電子機器取付け装置の前記第二方向用係合部が係合し、電子機器の後端側に装着される逆方向装着が可能であることを特徴とする電子機器取付け構造である。
【００１９】
また同様の課題を解決する請求項３に記載の発明は、電子機器の後端側をパネル部材に設けられた開口に挿入し、電子機器の後端側に電子機器取付け装置を装着し、電子機器取付け装置の一部をパネル部材に当接させて電子機器をパネル部材に取付ける電子機器取付け構造において、電子機器の筐体に第一係合部と第二係合部が設けられ、電子機器取付け装置は、枠状であって前後方向が前記電子機器の筐体を挿入可能に連通開口する本体部と、第一方向用係合部及び第二方向用係合部が設けられ、電子機器取付け装置は、前記本体部の一方の開口を先頭にして、電子機器の前記第一係合部と電子機器取付け装置の前記第一方向用係合部が係合し、電子機器の後端側に装着される正方向装着と、前記本体部を裏返して他方の開口を先頭にして、電子機器の前記第二係合部と電子機器取付け装置の前記第二方向用係合部が係合し、電子機器の後端側に装着される逆方向装着が可能であることを特徴とする電子機器取付け構造である。
【００２０】
本発明の電子機器取付け構造においても、電子機器取付け装置を使用するものであり、電子機器取付け装置は、本体部の一方の開口を先頭にして電子機器の後端側に装着される正方向装着と、本体部を裏返して他方の開口を先頭にして電子機器の後端側に装着される逆方向装着が可能である。そして本発明の電子機器取付け構造では、正方向装着における装着状態と逆方向装着における装着状態は、パネル部材に対する当接状態が異なるので、電子機器を実質的に支持するパネル部材の被押圧部を変更することができ、取付レイアウトの自由度が高い。
加えて本発明の電子機器取付け構造では、電子機器側に複数の機器側係合部又は第一・第二係合部が設けられている。一方、本発明では、電子機器取付け装置に第一方向用係合部及び第二方向用係合部が設けられている。
そして正方向装着の際に第一方向用係合部は特定の機器側係合部と係合し、逆方向装着の際に第二方向用係合部は特定の機器側係合部と係合する。そのため本発明によると正方向装着においても逆方向装着においても、電子機器取付け装置を電子機器にしっかりと装着することができ、電子機器の取付け強度が高い。
【００２１】
また請求項４に記載の発明は、正方向装着の際に第二方向用係合部は機器側係合部と係合せず、逆方向装着の際に第一方向用係合部は機器側係合部と係合しないことを特徴とする請求項２又は３に記載の電子機器取付け構造である。
【００２２】
本発明の電子機器取付け構造は、第一方向用係合部と第二方向用係合部を有する構成が前提となっており、正方向装着の際には第二方向用係合部は機器側係合部と係合せず、逆方向装着の際に第一方向用係合部は機器側係合部と係合しない。すなわち一方の装着姿勢を取る場合は、一部の係合部が機器側係合部と係合し、一部の係合部は機器側係合部と係合しない。そのため本発明の電子機器取付け構造は、取付け装置の着脱が容易であり、ひいては電子機器の着脱が容易となる。
【００２３】
また請求項５に記載の発明は、正方向装着の際に第二方向用係合部は機器側係合部と接触せず、逆方向装着の際に第一方向用係合部は機器側係合部と接触しないことを特徴とする請求項２又は３に記載の電子機器取付け構造である。
【００２４】
本発明の電子機器取付け構造についても第一方向用係合部と第二方向用係合部を有する構成が前提となっており、正方向装着の際に第二方向用係合部は機器側係合部と接触せず、逆方向装着の際に第一方向用係合部は機器側係合部と接触しない。そのため本発明の電子機器取付け構造は、取付け装置の着脱が容易であり、ひいては電子機器の着脱が容易となる。
【００２５】
また請求項６に記載の発明は、正方向装着における電子機器取付け装置が当接するパネル部材の位置と、逆方向装着における電子機器取付け装置が当接するパネル部材の位置が異なることを特徴とする請求項１乃至５のいずれかに記載の電子機器取付け構造である。
【００２６】
本発明の電子機器取付け構造では、正方向装着による場合と、逆方向装着による場合で電子機器取付け装置が当接する位置が異なる。本発明の実施態様として、例えば正方向装着による場合と逆方向装着による場合で電子機器取付け装置が当接する開口の辺が異なる様な構成が考えられる。
そのため縦横両方向への複数取付けを、単一構造の取付け装置を使用して行うことができ、かつその作用効果が確実である。
【００２７】
また請求項７に記載の発明は、電子機器取付け装置の本体部は、４辺を有する略長方形枠状であり、第一方向用係合部は本体部の対向する二辺部であって一方の開口側に設けられ、第二方向用係合部は本体部の他の対向する二辺部であって他方の開口側に設けられ、さらに本体部には、パネル部材と当接して電子機器との間でパネル部材を挟む方向に押圧する押圧部材が一体的に形成され、押圧部材は、第一方向用係合部又は第二方向用係合部が設けられた本体部の辺であって、第一方向用係合部又は第二方向用係合部が設けられた開口側に対して反対側の開口側に設けられていることを特徴とする請求項２乃至５のいずれかに記載の電子機器取付け構造である。
【００２８】
本発明の電子機器取付け構造では、電子機器取付け装置の本体部は、４辺を有する略長方形枠状である。そして第一方向用係合部は本体部の対向する二辺部であって一方の開口側に設けられ、第二方向用係合部は本体部の他の対向する二辺部であって他方の開口側に設けられている。例えば本体部が４辺ａ，ｂ，ｃ，ｄ（時計回り）の長方形であって、辺ａ，ｃが平行、同じく辺ｂ，ｄが平行であるとすると、一組の辺ａ，ｃに第一方向用係合部が設けられている。また第二方向用係合部は、もう一組の辺ｂ，ｄに設けられている。また本発明では、電子機器取付け装置の本体部は、枠状であり、前後方向が貫通開口しているが、前記した第一方向用係合部は、一方の開口側にあり、第二方向用係合部は、他方の開口側にある。
【００２９】
またさらに押圧部材は、第一方向用係合部又は第二方向用係合部が設けられた本体部の辺であって、第一方向用係合部又は第二方向用係合部が設けられた開口側に対して反対側の開口側に設けられている。
従って各辺に係合部と押圧部材があり、これらは各辺の一方の開口側と他方の開口側に設けられている。そして同じ向きに係合部と押圧部材が設けられた辺が向き合って配置されている。
本発明の電子機器取付け構造では、電子機器取付け装置を正方向装着すると、特定の二辺の開口側に設けられた押圧部材がパネル部材と当接し、電子機器との間でパネル部材を挟む。また当該押圧部材が当接する辺の後端側開口近傍には第一方向用係合部があり、第一方向用係合部は電子機器側に設けられた機器側係合部と係合する。そのため第一方向用係合部によって電子機器取付け装置の後端側への移動は阻止されている。そのため、押圧部材によって第一方向用係合部は機器側係合部に押圧され、両者の間の遊びが解消される。特に本発明では、第一方向用係合部が設けられた辺と同一の辺に押圧部が設けられているから、押圧部の押圧力は直接的に第一方向用係合部に掛かる。そのため本発明では、押圧部材によって第一方向用係合部はより直接的に機器側係合部に押圧され、両者の間の遊びを無くす作用が強い。
【００３０】
また本発明では、電子機器取付け装置を構成する辺の一方の開口側に押圧部材があり、他方の開口側に第一方向用係合部があるので、押圧部材と第一方向用係合部の間の長さが比較的長い。そのため電子機器は、第一方向用係合部によってより後方から支持され、電子機器の端部側を支持することとなるので、電子機器の取付け状態が安定する。
電子機器取付け装置を逆方向装着した場合も同様であり、他の二辺の開口側に設けられた押圧部材がパネル部材と当接し、電子機器との間でパネル部材を挟む。また電子機器取付け装置は、当該押圧部材が当接する辺の、後端側開口近傍に設けられた第二方向用係合部が電子機器側に設けられた機器側係合部と係合する。そのため第二方向用係合部によって電子機器取付け装置の後端側への移動は阻止され、さらに押圧部材の反力によって第一方向用係合部は機器側係合部に押圧されるので両者の間の遊びが解消される。
【００３１】
また逆方向装着においても第二方向用係合部が設けられた辺と同一の辺に押圧部材が設けられているから、押圧部材の押圧力は直接的に第二方向用係合部に掛かり、押圧部材によって第二方向用係合部はより直接的に機器側係合部に押圧され、両者の間の遊びが極めて小さなものとなる。
その結果、第一方向用係合部と機器側係合部の係合強度が増す。
【００３２】
また請求項８に記載の発明は、電子機器取付け装置の本体部は、４辺の壁部によって構成される略長方形枠状であり、電子機器取付け装置は押圧部材を有し、電子機器の前端部の周面に設けられる縁部がパネル部材の開口部の周縁に当接し、前記押圧部材は電子機器の縁部とによりパネル部材を挾持する方向に向かって押圧するものであり、前記押圧部材は本体部を構成する壁部の端面にあり、押圧部材の外壁面は、本体部を構成する壁部と同一平面にあるか、又はより内側の位置にあることを特徴とする請求項１乃至７のいずれかに記載の電子機器取付け構造である。
【００３３】
本発明の電子機器取付け構造では、電子機器取付け装置の本体部は、４辺の壁部によって構成される略長方形枠状である。また本発明では、押圧部材を有する。そして電子機器の前端部の周面に設けられる縁部がパネル部材の開口部の周縁に当接し、押圧部材は電子機器の縁部とによりパネル部材を挾持する方向に向かって押圧する。また本発明では、前記押圧部材が一体的に形成され、押圧部材は本体部を構成する壁部の端面にある。
そして本発明では、押圧部材の外壁面は、本体部を構成する壁部と同一平面にあるか、又はより内側の位置にある。すなわち本発明では、本体部を構成する壁部が最も外側にあり、押圧部材の外壁面は、これと同一面であるか、これよりも内側にある。
そのため本発明の電子機器取付け構造を採用して、電子機器を縦又は横に並べた時、隣接する押圧部材同士が干渉することがない。
【００３４】
また請求項９に記載の発明は、請求項１乃至８のいずれかに記載の電子機器の取付け構造であって、縦長又は横長の長孔に複数の電子機器が並べて挿入され、各電子機器の正面部は長孔の前面に位置し、後端側は長孔の裏面側に位置し、長孔の前面側においては、隣接する電子機器又はこれに付属する部材の正面部がそのいずれかの位置で互いに接し、長孔の裏面側においては、長孔の対向した長辺を構成する長辺状縁部の裏面部に電子機器取付け装置の一部が接していることを特徴とする電子機器取付け構造である。
【００３５】
本発明の電子機器取付け構造は、具体的に縦方向複数取付や横方向複数取付けを行った場合の構成を開示するものである。
すなわち本発明の電子機器取付け構造では、縦長又は横長の長孔に複数の電子機器が並べて挿入され、各電子機器の正面部は長孔の前面に位置し、後端側は長孔の裏面側に位置している。そして長孔の前面側では、隣接する電子機器又はこれに付属する部材の正面部がそのいずれかの位置で互いに接している。
一方、長孔の裏面側では、長孔の対向した長辺を構成する長辺状縁部の裏面部に電子機器取付け装置の一部が接している。すなわち長孔が縦方向に長いものであるならば、長孔の対向した長辺は、縦方向に延びる。そして本発明では、当該縦方向に伸びる長孔の長辺を構成する長辺状縁部の裏面部に電子機器取付け装置の一部が接している。長孔が横方向に延びるものであっても同様であり、長孔の対向した長辺は、横方向に延び、当該横方向に伸びる長孔の長辺を構成する長辺状縁部の裏面部に電子機器取付け装置の一部が接している。
【００３６】
また請求項１０に記載の発明は、電子機器の後端側に装着され、他部材と当接して電子機器を取付ける電子機器取付け装置において、枠状であって前後方向が連通開口する本体部を有し、本体部の一方の開口を先頭にして電子機器の後端側に装着される正方向装着と、本体部を裏返して他方の開口を先頭にして電子機器の後端側に装着される逆方向装着が可能であり、正方向装着における装着状態と逆方向装着における装着状態は、他部材に対する当接状態が異なることを特徴とする電子機器取付け装置である。
【００３７】
また請求項１１に記載の発明は、電子機器の後端側に装着され、他部材と当接して電子機器を取付ける電子機器取付け装置において、枠状であって前後方向が前記電子機器の筐体を挿入可能に連通開口する本体部と、第一方向用係合部及び第二方向用係合部が設けられ、本体部の一方の開口を先頭にして、電子機器の一部と電子機器取付け装置の第一方向用係合部を係合させる正方向装着と、本体部を裏返して他方の開口を先頭にして、電子機器の一部と電子機器取付け装置の前記第二方向用係合部を係合させる逆方向装着が可能であることを特徴とする電子機器取付け装置である。
【００３８】
上記した請求項１０，１１は、電子機器の取付け装置に関する発明である。
本発明の電子機器の取付け装置は、前記した取付け構造に使用するものであり、本体部の一方の開口を先頭にして電子機器の後端側に装着される正方向装着と、本体部を裏返して他方の開口を先頭にして電子機器の後端側に装着される逆方向装着が可能である。
また特に請求項１０に記載の電子機器取付け装置では、正方向装着における装着状態と逆方向装着における装着状態は、他部材に対する当接状態が異なるので、電子機器を実質的に支持する他部材の被押圧部を変更することができ、縦横両方向への複数取付けを、単一構造の取付け装置を使用して行うことができる。
また請求項１１に記載の発明では、いずれの装着方向においても、電子機器の一部と電子機器取付け装置の係合部が係合する。
【００３９】
また請求項１２に記載の発明は、電子機器の後端側に装着され、他部材と当接して電子機器を取付ける電子機器取付け装置において、枠状であって前後方向が連通開口する本体部を有し、本体部の一方の開口を先頭にして電子機器の後端側に装着される正方向装着と、本体部を裏返して他方の開口を先頭にして電子機器の後端側に装着される逆方向装着が可能であり、前記正方向装着の際に他部材等と当接する正方向当接部と、逆方向装着の際にパネル部材等と当接する逆方向当接部を有し、正方向当接部と逆方向当接部は、電子機器取付け装置を連通開口方向に沿って正投影視した時に異なる位置に存在することを特徴とする電子機器取付け装置である。
【００４０】
本発明の電子機器取付け装置は、先の発明と同様の作用効果を有するものであり、本体部の一方の開口を先頭にして電子機器の後端側に装着される正方向装着と、本体部を裏返して他方の開口を先頭にして電子機器の後端側に装着される逆方向装着が可能である。
また特に本発明では、正方向装着の際に他部材等と当接する正方向当接部と、逆方向装着の際に他部材等と当接する逆方向当接部を有する。そして前記した正方向当接部と逆方向当接部は、電子機器取付け装置を連通開口方向に沿って正投影視した時に異なる位置に存在する。
従って本発明の電子機器取付け装置によると、正方向装着による場合と、逆方向装着による場合で電子機器取付け装置が当接する位置が異なる。そのため本発明の電子機器取付け装置によると、電子機器を取付ける際の取付レイアウトの自由度が高い。
【００４１】
【発明の実施の形態】
以下さらに本発明の実施形態について説明する。なお説明を簡単にするために、「上下」等の文言を使用する場合があるが、上下の関係は、原則的に電子機器の通常の取付け姿勢を基準とするものであり、表示部１０側が上で、操作部１１側が下である。また前後の関係についても電子機器の通常の取付け姿勢を基準とし、表示部１０がある方向が前方であり、その反対が後方である。

【００４３】
本実施形態は、電子機器たる圧力センサーを制御盤の正面パネルに取付ける場合の取付け構造を示すものである。
各図において、１は、本発明の実施形態の電子機器取付け構造を示す。本実施形態の取付け構造１は、電子機器２に係合部形成部材３を装着し、さらにその後部に電子機器取付け装置５を装着して制御盤のパネル６に電子機器２を取付けるものである。
以下、各部材について説明する。
【００４４】
電子機器２は、前記したように圧力センサーであり、本体部は、略直方体をしている。通常の取付け姿勢を基準としたとき、電子機器２は図６の様にやや横長形状である。
すなわち電子機器２は、正面視が横長で略直方体の筐体８を備え、その正面側には図６に示すように表示部１０と操作部１１が設けられている。
表示部１０は、公知の７セグメントによるものであり、数字等を４文字表示することができ、検出圧力や設定値、設定モード等を表示することができる。
操作部１１は、表示部１０の下部にあって、４個のスイッチ１２，１３，１４，１５によって構成され、１２はセットスイッチ、１３は設定値上昇スイッチ、１４は設定値降下スイッチ、１５はモード設定スイッチとして機能する。
【００４５】
電子機器２の後端側には、図２の様に電気信号等を外部に取り出すためのコネクター１６が一体的に形成されている。また電子機器２の後端側の中央には、圧力を検知するための接続金具１７が取付けられている。接続金具１７は、チューブやホース等の配管が接続されるものであり、本実施形態では、後端方向への接続口と、垂直方向への接続口を有するものが図示されている。
【００４６】
電子機器２の筐体８は、表示部１０等が設けられた前方筐体２０と、コネクター１６が形成された後方筐体２１が、４か所の爪状係合部１９によって結合合体されたものであり、実質的に一体的形状をしている。
【００４７】
筐体８の後方筐体２１の後端側の４隅は表示部１０側の面に対して平行な平坦面であり、当該平坦部に後記する係合部形成部材３の係止爪６２が係合する。
４隅に設けられた平坦部の内、上部（図２参照）に設けられた上部側平坦部２５，２６は、下部に設けられた下部側平坦部２７（一方の平坦部は図示せず）よりも前方側（表示部寄り）に位置している。
【００４８】
次に係合部形成部材３について説明する。係合部形成部材３は、樹脂の射出成形によって作られたものであり、図３に示すように枠状をしている。
すなわち係合部形成部材３は、４面の壁部３０，３１，３２，３３によって構成された枠状の成形物であり、前後方向に連通開口する。
係合部形成部材３の壁部３０，３１，３２，３３が囲む空間は、略直方体であり、図３のＡ−Ａ平面における断面形状は長方形である。すなわち図３の上下に水平に図示された壁部３０，３２は、長辺に相当し、左右に垂直方向に図示された壁部３１，３３は、短辺に相当する。
【００４９】
上記した４面の壁部３０，３１，３２，３３には、いずれも機器側係合部を形成する係合部形成片３４，３５，３６，３７が一体成形されている。
係合部形成片３４，３５，３６，３７は、それぞれギザが並べて形成された機器側係合面３８，４０，４２，４４と、平面状の非係合面３９，４１，４３，４５を並べて設けたものである。
【００５０】
すなわち各係合部形成片３４，３５，３６，３７に設けられた機器側係合面３８，４０，４２，４４は、断面が三角形の山が多数、平行に並べられて設けられたものである。三角形の山は平行であって係合部形成部材３の連通開口方向に沿って並んでいる。より具体的に説明すると、各山の後方側斜面２８（電子機器の後方側に向かう面）は、図３（ｂ）の様に各壁部３０，３１，３２，３３の平面に対して緩やかに傾斜しているのに対し、前方側斜面２９（電子機器の表示部側に向かう面）は、各壁部３０，３１，３２，３３の平面に対してよりきつい傾斜となっている。言い換えると、機器側係合面３８，４０，４２，４４は、いずれも前方（表示部側）に向かって順目であり、後方に向かって逆目である。
非係合面３９，４１，４３，４５は、前記した様に機器側係合面３８，４０，４２，４４の横に併置され、その幅及び長さは、係合部形成片３５，３６，３７，３８と略等しい。
【００５１】
各係合部形成片３４，３５，３６，３７の両脇部分には、前後方向に伸びる低い凸壁２４が設けられている。
【００５２】
壁部３０，３１，３２，３３に形成された各係合部形成片３４，３５，３６，３７の位置について説明すると、各係合部形成片３４，３５，３６，３７は、それぞれの壁部３０，３１，３２，３３の中央部にあり、機器側係合面３８，４０，４２，４４と非係合面３９，４１，４３，４５との境界は、各壁部３０，３１，３２，３３の中心線上に位置している。
【００５３】
図１，３，４に示す様に、係合部形成部材３を後方側から見たとき、各機器側係合面３８，４０，４２，４４は、各壁部３０，３１，３２，３３の中心軸に対して反時計方向の位置にある。また非係合面３９，４１，４３，４５は係合部形成部材３を後方側から見たとき、各壁部３０，３１，３２，３３の中心軸に対して時計方向の位置にある。
【００５４】
従って、対向する壁部（３０，３２）（３１，３３）の各係合面同士（３８，４２）（４０，４４）は面対称ではなく、点対称である。すなわち、対抗する壁部（３０，３２）（３１，３３）の各係合面同士（３８，４２）（４０，４４）は、電子機器２の本体部の前後方向における中心点を中心に点対称となる様に設けられている。そして各係合面と面する位置には、対向する壁部３０，３１，３２，３３の非係合面３９，４１，４３，４５がある。
【００５５】
図３において上部に図示された上部長辺側の壁部３０と、下部に図示された下部長辺側の壁部３２には、係合部形成片３４，３６の両脇に補強壁５０，５１，５２，５３が設けられている。各補強壁５０，５１，５２，５３の前後方向の長さは、係合部形成片３４，３６のそれよりも短い。また上部長辺側の壁部３０に設けられた補強壁５０，５１と下部長辺側の壁部３２に設けられた補強壁５２，５３を比較すると、下部長辺側の壁部３２に設けられた補強壁５２，５３の方が上部側の補強壁５０，５１よりも長い。
【００５６】
図３の左右に垂直方向に図示された壁部３１，３３（短辺側の壁部）に注目すると、壁部３１，３３では、前記した係合部形成片３５，３７の両脇側に係止片５５，５６，５７，５８が設けられている。
各係止片５５，５６，５７，５８は、いわゆるフック爪であり、いずれも先端（後部側の先端）部分に鉤状の係止爪６２が形成されている。各係止爪６２はいずれも内側に向いている。
【００５７】
係止片５５，５６，５７，５８と係合部形成片３５，３７の間には溝６０があり、係止片５５，５６，５７，５８は舌状であって係合部形成片３５，３７に対して独立して撓むことができる。
係止片５５，５６，５７，５８は前記した電子機器２の平坦部２５，２６，２７と係合するものであり、係止片５５，５６，５７，５８の長さは、電子機器の平坦部２５，２６，２７の位置と合致する様に設計されている。すなわち図３の上部に図示された係止片５５，５８は、電子機器２の上部側平坦部２５，２６の位置に合わせて長さが短く、下部に図示された係止片５６，５７は下部側平坦部２７の位置に合わせて長さが長い。
【００５８】
前記した４面の壁部３０，３１，３２，３３は、前方側で互いに繋がっている。また係合部形成部材３の最先端部分には全周にわたるフランジ部６１が設けられている。
フランジ部６１の内面側には図示しない係合部があり、電子機器２の前面側と係合する。
【００５９】
次に電子機器取付け装置について説明する。
電子機器取付け装置５は、樹脂によって成形されたものであり、図５に示すように４面の壁部７０，７１，７２，７３で囲まれた枠状をしており、前後方向が連通開口する。また電子機器取付け装置５は、４個の係合片７５，７６，７７，７８と４個の押圧部８０，８１，８２，８３を持つ。
すなわち電子機器取付け装置５の本体部８５は、４辺を有する略長方形枠状である。そのため各辺を構成する壁部７０，７１，７２，７３は、対向する壁部同士が平行であり、隣接する壁部同士は互いに垂直である。
また本体部８５の断面形状は長方形であり、電子機器２の断面形状に略等しい。
【００６０】
そして各壁部７０，７１，７２，７３にそれぞれ一つづつ係合片７５，７６，７７，７８と押圧部８０，８１，８２，８３が設けられている。各係合片７５，７６，７７，７８と押圧部８０，８１，８２，８３は、いずれの壁部７０，７１，７２，７３においても、その両端側に設けられている。すなわちいずれの壁部７０，７１，７２，７３についても、一方の端部側（一方の開口側）に一つの係合片７５，７６，７７，７８があり、他方の端部側（他方の開口側）に一つの押圧部８０，８１，８２，８３がある。
【００６１】
各係合片７５，７６，７７，７８は、いわゆるフック爪である。各係合片７５，７６，７７，７８は、各壁部７０，７１，７２，７３の中央にあり、係合片７５，７６，７７，７８の両脇には溝６３があり、係合片７５，７６，７７，７８は根元側だけが他の部分と接合された舌状であって、他の部分から独立して撓むことができる。また係合片７５，７６，７７，７８は撓みやすい様に、壁部７０，７１，７２，７３の他の部分に比べて肉厚が薄い。係合片７５，７６，７７，７８の内側の面は、壁部７０，７１，７２，７３の他の部分と揃っており、外側の面は、他の部分に対して凹んでいる。ただし、係合片７５，７６，７７，７８の開放端は、図５（ｂ）の様にやや外側に曲がった様な形状となっており、開放端については壁部７０，７１，７２，７３の他の部分と同一平面にある。
【００６２】
また係合片７５，７６，７７，７８の先端開放側の端部の内側にフック爪として機能する係合部８６，８７，８８，８９が設けられている。係合部８６，８７，８８，８９は、図５（ａ）（ｂ）の様な断面形状が３角状をした一山のノッチであり、根元側の傾斜面９２の角度が緩く、開放側の傾斜面９１の角度が急である。係合部８６，８７，８８，８９は、係合片７５，７６，７７，７８の全幅に渡るものではなく、図５（ａ）の様に約半分の幅にだけ設けられている。係合部８６，８７，８８，８９が設けられた位置は、いずれの係合片７５，７６，７７，７８でも同一であり、開放側を上にして係合部８６，８７，８８，８９の方向（内側）から見たとき、左側に寄った位置である。
【００６３】
また押圧部材８０，８１，８２，８３は、弓状の部材である。そして押圧部材８０，８１，８２，８３は、弓の中央に相当する部分の背後側が壁部７０，７１，７２，７３の一方の端面に接続されている。すなわち各壁部７０，７１，７２，７３の一方の端部には前記した係合片７５，７６，７７，７８があり、他端側の端面には弓状の押圧部材８０，８１，８２，８３が形成されている。
前記したように押圧部材８０，８１，８２，８３は、中央部分が壁部７０，７１，７２，７３と接続されており、両端は自由端となっている。そして当該自由端は壁部７０，７１，７２，７３の端面から離れる方向に湾曲している。
押圧部材８０，８１，８２，８３は、前記したように壁部７０，７１，７２，７３の端面にあり、押圧部材８０，８１，８２，８３の外周側の平面は、壁部７０，７１，７２，７３の他の部位を構成する平面と同一平面内にある。
【００６４】
電子機器取付け装置５の長短の４辺を構成する壁部７０，７１，７２，７３は、いずれも同一の形状であり（大きさは異なる）、一方の端部に係合片７５，７６，７７，７８及び係合部８６，８７，８８，８９があり、他方の端面に押圧部材８０，８１，８２，８３が設けられている。しかしながら、壁部７０，７１，７２，７３の向きは異なっている。すなわち対向する平行２辺の壁部（７０，７２）（７１，７３）は同一方向に取付けられているが、対向する平行２辺の壁部（７０，７２）（７１，７３）同士はこれと逆向きに取付けられている。より具体的に説明すると、対向する平行２辺の壁部（７０，７２）は同一の向きであり、もう一つの対向する平行２辺の壁部（７１，７３）は同一の向きである。隣り合う壁部同士は互いに逆向きに設けられている。
従って電子機器取付け装置５の各開放端面側に注目すると、押圧部材８０，８１，８２，８３と、係合片７５，７６，７７，７８が互い違いに存在する。例えば図５を見ると、電子機器取付け装置５の手前側の端面の上部の長辺を構成する壁部７０と下部の長辺を構成する壁部７２に押圧部材８０，８２が設けられており、左右の短辺を構成する壁部７１，７３には係合片７６，７８が設けられている。逆に奥側の端面では、上部の長辺を構成する壁部７０と下部の長辺を構成する壁部７２に係合片７５，７７があり、左右の短辺を構成する壁部７１，７３には押圧部材８１，８３が設けられている。
【００６５】
前記した様に、係合片７５，７６，７７，７８及び係合部８６，８７，８８，８９の形状は、いずれも同一の形状であるが、壁部７０，７１，７２，７３自体の形成方向が異なるため、長辺を構成する壁部７０，７２に設けられた係合部８６，８８と、短辺を構成する壁部７１，７３に設けられた係合部８７，８９は、係合方向が異なる。
【００６６】
そこで説明の便宜上、短辺を構成する壁部７１，７３に設けられた係合片７６，７８及び係合部８７，８９を第一方向係合片及び第一方向用係合部と称し、長辺を構成する壁部７０，７２に設けられた係合片７５，７７及び係合部８６，８８を第二方向係合片及び第二方向用係合部と称することとする。
またこれに併せて第一方向用係合部８７，８９が設けられた壁部７１，７３に設けられた押圧部材８１，８３を正方向押圧部材と称し、第二方向用係合部８６，８８が設けられた壁部７０，７２に設けられた押圧部材８０，８２を逆方向押圧部材と称する。
なお正方向押圧部材８１，８３は、請求項１０の正方向当接部として機能し、逆方向押圧部材８０，８２は、請求項１０の逆方向当接部として機能する。
【００６７】
従って本実施形態では、第一方向用係合部８７，８９は図５の手前側に図示され、本体部８５の対向する短辺部であって手前側の開口側に設けられている。また第二方向用係合部８６，８８は本体部８５の他の対向する二辺たる長辺部であって他方の開口側に設けられている。また本体部８５には、正方向押圧部材８１，８３と逆方向押圧部材８０，８２が一体的に形成され、正方向押圧部材８１，８３は、第一方向用係合部８７，８９が設けられた本体部８５の短辺側壁部７１，７３の端面に設けられている。一方、逆方向押圧部材８０，８２は、第二方向用係合部８６，８８が設けられた本体部８５の長辺側壁部７０，７２の端面に設けられている。
【００６８】
前記した様に係合部８６，８７，８８，８９が設けられた位置は、いずれの係合片７５，７６，７７，７８でも同一であり、開放側を上にして係合部８６，８７，８８，８９の方向（内側）から見たとき、左側に寄った位置であるが、壁部７０，７１，７２，７３自体の形成方向が異なる。そのため電子機器取付け装置５を一方の開口側から観察したとき、第一方向用係合部８７，８９と第二方向用係合部８６，８８は、偏心方向が逆になる。具体的には、電子機器取付け装置５をいずれか一方の開口側から観察したとき、手前側の開口近傍に設けられた係合部は、常に反時計方向の位置に偏心し、奥側の開口近傍に設けられた係合部は、常に時計方向の位置に偏心している。
また対向する短辺側の壁部７１，７３に第一方向用係合部８７，８９があるが、第一方向用係合部８７，８９は偏心した位置にあるから、第一方向用係合部８７，８９同士は面対称ではなく、点対称である。第一方向用係合部８７，８９は前後方向における中心点を中心に点対称となる様に設けられている。
同様に第二方向用係合部８６，８８についても面対称ではなく、点対称である。したがって電子機器取付け装置５は全体として前後方向における中心点を中心に点対称形状となっている。
【００６９】
次に、本発明の電子機器取付け構造における各部材同士の関係を取付け手順を追って説明する。
まず最初に電子機器２に係合部形成部材３を装着する。図４は、電子機器２に係合部形成部材３を装着した状態を表す。係合部形成部材３は、電子機器２の前面部分の外周にフランジ部６１の内面が係合して前面側を保持する。さらに係合部形成部材３の係止片５５，５６，５７，５８が電子機器２の後端部の４隅に設けられた平坦部２５，２６，２７と係合して後端側を保持する。この様に電子機器２の前面側と後端側で係合部形成部材３が係合し、係合部形成部材３は電子機器２を包み込むようにして装着される。なお、電子機器２に係合部形成部材３を装着する際には、係止片５５，５６，５７，５８を撓ませて自由端側を押し開き、電子機器２を挿入することとなる。前記した様に、係止片５５，５６，５７，５８は舌状であって係合部形成片３５，３７に対して独立して撓むことができるので、電子機器２に対して係合部形成片３５，３７を装着する作業は容易である。
【００７０】
続いて、電子機器２と係合部形成部材３を一体化した部材を制御盤等のパネル６に設けられた長孔状の開口９０に挿入する。ここで本実施形態の電子部品取付け構造は、縦方向の長孔に複数個の電子機器を並べて取付ける縦方向複数取付と、横方向の長孔に複数個の電子機器を並べて取付ける横方向複数取付の双方が可能であるが、先に縦方向複数取付けを行う場合について説明する。
図７は、電子機器を縦方向複数取付する場合に使用する開口の正面図である。図８は、本発明の実施形態の電子機器の取付け構造によって、電子機器を縦に並べて取付けた状態を後端側から見た斜視図である。図９は、電子機器を縦に並べて取付ける場合の電子機器取付け装置と係合部形成部材及びパネルの関係を後端側から見た斜視図である。図１０は、電子機器を縦方向複数取付する場合における機器側係止部と正方向・逆方向係止部との関係、及び押圧部材等の関係を示す概略説明図である。図１１は、本発明の実施形態の電子機器の取付け構造であって正方向装着したものを背面側から見た背面図である。
【００７１】
縦方向複数取付けを行う場合には、図７に示すような長孔状の開口９０に、電子機器２を前方から挿入し、電子機器２の後端側に電子機器取付け装置５を正方向に取付け、正方向装着を行なう。
すなわち図１，８，９に示すように、短辺を構成する壁部７１，７３に設けられた正方向押圧部材８１，８３がパネル６と当接する様な取付け姿勢で電子機器取付け装置５を電子機器２の後端側に装着する。
その結果、開口９０の前側においては、係合部形成部材３のフランジ部６１が開口９０の前側の縁と当接し、開口９０の裏側においては、正方向押圧部材８１，８３が開口９０の裏側の長辺状縁部９３（図７，８）と当接し、フランジ部６１と電子機器取付け装置５によって開口９０の縁を挟み込む。
【００７２】
電子機器取付け装置５を正方向に取付けた状態では、同じく短辺を構成する壁部７１，７３に設けられた第一方向用係合部８７，８９が係合部形成部材３の短辺を構成する壁部３１，３３に設けられた機器側係合面４０，４４と係合する。
すなわち機器側係合部を構成する機器側係合面３８，４０，４２，４４は、後方側から見て、各壁部３０，３１，３２，３３の中心線上よりも反時計方向の位置にある。
一方電子機器取付け装置５の第一方向用係合部８７，８９は、正方向押圧部材８１，８３と同一の壁部７１，７３にあり、且つ正方向押圧部材８１，８３と反対側の開口端部にある。そして前記した様に正方向押圧部材８１，８３がパネル６と当接する姿勢で電子機器取付け装置５を装着するから、第一方向用係合部８７，８９は、パネル６から離れた位置にある。
【００７３】
一方、電子機器取付け装置５の各係合部８６，８７，８８，８９は、前記した様に各係合片７５，７６，７７，７８の開放側を上にして係合部８６，８７，８８，８９の方向（内側）から見たとき、いずれも左側に寄った位置であり、電子機器取付け装置５をいずれか一方の開口側から観察したとき、手前側の開口近傍に設けられた係合部８６，８７，８８，８９は、常に反時計方向の位置に来る。
そのため短辺を構成する壁部７１，７３に設けられた正方向押圧部材８１，８３がパネル６と当接する様な取付け姿勢で電子機器取付け装置５を電子機器２の後端側に装着すると、図１０に示すように、必然的に第一方向用係合部８７，８９の位置が、電子機器２の短辺側に形成された機器側係合面４０，４４の位置と一致する。
従って、正方向押圧部材８１，８３がパネル６と当接する様な取付け姿勢で電子機器取付け装置５を電子機器２の後端側に装着すると、電子機器取付け装置５の第一方向用係合部８７，８９が、機器側係合面４０，４４と係合する。
図１２は、第一方向用係合部８７，８９と機器側係合面４０，４４との係合状態を示す要部拡大断面図である。
【００７４】
一方、第二方向用係合部８６，８８は、後端側から見て、時計方向の位置に偏心しているから、図１０，１１に示す様に係合部形成部材３の長辺を構成する壁部３０，３２に設けられた，係合部形成片３４，３６の平坦な非係合面３９，４３と合致する。
【００７５】
係合部形成片３４，３６の非係合面３９，４３は平面状であるから、第二方向用係合部８６，８８とは係合しない。すなわち正方向装着の際に第二方向用係合部８６，８８は機器側係合部と接触せず、係合しない。
この様に第一方向用係合部８７，８９が、機器側係合面４０，４４と係合することにより、電子機器取付け装置５の後端側への移動は阻止されている。また正方向押圧部材８１，８３は、弾性を有する部材であるから、正方向押圧部材８１，８３の押圧力によって第一方向用係合部８７，８９は機器側係合部４０，４４に押圧され、両者の間の遊びが消える。
【００７６】
すなわち正方向押圧部材８１，８３は、弓状であって弾性を有するから、正方向押圧部材８１，８３がパネル６の背面と当接することによって電子機器取付け装置５は後方に向かって付勢され、両者の遊びがなくなってがたつきが解消される。特に本実施形態では、第一方向用係合部８７，８９が設けられた辺と同一の辺に正方向押圧部材８１，８３が設けられているから、正方向押圧部材８１，８３の押圧力は直接的に第一方向用係合部８７，８９に掛かる。そのため本実施形態では、正方向押圧部材８１，８３によって第一方向用係合部８７，８９は、より直接的に機器側係合部に押圧され、両者の間の遊びを無くす作用が強い。
【００７７】
また本実施形態では、電子機器取付け装置５を構成する辺の一方の開口側に正方向押圧部材８１，８３があり、他方の開口側に第一方向用係合部８７，８９があるので、押圧部材８１，８３と係合部８７，８９の間の長さが比較的長い。そのため電子機器２は、第一方向用係合部８７，８９によってより後方から支持され、電子機器２の端部側を支持することとなるので、電子機器２の取付け状態が安定する効果がある。

実際の電子機器取付け作業は、電子機器取付け装置５を所定の姿勢に保持し、正方向押圧部材８１，８３側の開口を先頭にして電子機器取付け装置５を電子機器２側に挿入する。そして正方向押圧部材８１，８３がパネル６の背面と当接し、且つ正方向押圧部材８１，８３が変形して反発力を生じるまで電子機器取付け装置５を押し込む。
ここで電子機器２側の機器側係合面３８，４０，４２，４４は、ギザを並べて形成された凹凸形状であり、凹凸を形成する三角山の方向が、いずれも前方に向かって順目である。また第一方向用係合部８７，８９は、図５（ａ）（ｂ）の様な断面形状が３角状をした一山のノッチであり、根元側の傾斜面９２が緩く、開放側の傾斜面９１が急である。
そのため電子機器取付け装置５を電子機器２の後端側に装着せんとして電子機器取付け装置５を前方側（表示部１０側）に押すと、第一方向用係合部８７，８９のノッチが機器側係合面４０，４４のギザに乗り上げる方向の分力が発生し、係合片７６，７８が外側に撓んで機器側係合面４０，４４のギザを次々に乗り越えてゆく。特に本実施形態では、係合片７６，７８の肉厚が、壁部７１，７３の他の部分に比べて薄く、撓みやすいので、軽い力をもって電子機器取付け装置５を挿入することができる。
【００７９】
また電子機器取付け装置５を電子機器２の後端側に装着せんとして電子機器取付け装置５を前方側に押す際、第二方向用係合部８６，８８は機器側係合部と接触しない。そのため電子機器取付け装置５を電子機器２の後端側に装着する作業には大きな力がいらず、簡単である。
その一方、機器側係合面３８，４０，４２，４４は、凹凸を形成する三角山の方向が、いずれも後方に向かって逆目であり、また第一方向用係合部８７，８９は、開放側の傾斜面９１が急である。
そのため電子機器取付け装置５に抜き方向の力が作用すると第一方向用係合部８７，８９には、より機器側係合面４０，４４のギザに食い込む方向の力が作用し、後退を強固に阻止する。
【００８０】
すなわち本実施形態では、機器側係合面４０，４４は、一定の方向に向いたギザ形状であり、直線的に配された凹凸状部材であるのに対し、第一方向用係合部８７，８９は、爪状であるから、両者によってラチェット様の逆転阻止構造が形成されている。そのため本実施形態では、電子機器取付け装置５の装着に大きな力を要せず、且つ後退を強固に阻止する。
【００８１】
電子機器２を縦方向複数取付した場合の様子は、図６，８の通りであり、縦長の長孔状開口９０に５個の電子機器２が並べて挿入され、各電子機器の正面部は開口９０の前面に位置する。
そして開口９０の前面側では、隣接する係合部形成部材３のフランジ部６１同士が互いに接している。従ってパネル６を正面側から見ると、電子機器２が縦に積み重なった状態で取付けられている。
また長孔状の開口９０の裏面側では、開口９０の対向した長辺を構成する長辺状縁部９３（図１，７参照）の裏面部に正方向押圧部材８１，８３の先端の辺が接している。
【００８２】
また本実施形態では、正方向押圧部材８１，８３は、壁部７０，７１，７２，７３の端面にあり、正方向押圧部材８１，８３の平面は、壁部７０，７１，７２，７３の他の部位を構成する平面と同一平面内にある。言い換えると押圧部材８１，８３は、壁部７０，７１，７２，７３で囲まれる面からはみ出さない。そのためパネル６の裏面側で、正方向押圧部材８１，８３同士が干渉することがない。
なお本実施形態では、押圧部材８０，８１，８２，８３の外周側の平面と、壁部７０，７１，７２，７３の他の部位を構成する平面が同一平面となる様に設計したが、押圧部材８３の外周側の平面が、より内側に入る様な形状に設計しても同様の作用効果が期待できる。
【００８３】
前記した様に本実施形態の電子機器取付け構造１は、電子機器取付け装置５を逆方向装着することにより、横方向複数取付けを行なうこともできる。
次に、電子機器２を横方向の長孔状開口９０に複数個並べて取付ける横方向複数取付について説明する。
【００８４】
図１３は、本発明の実施形態の電子機器の取付け構造であって電子機器取付け装置を逆方向装着した場合を後端側から見た斜視図である。図１４は、電子機器を横方向複数取付する場合に使用する開口の正面図である。図１５は、本発明の実施形態の電子機器の取付け構造によって、電子機器を横に並べて取付けた状態を正面側から見た斜視図である。図１６は、本発明の実施形態の電子機器の取付け構造によって、電子機器を横に並べて取付けた状態を後端側から見た斜視図である。図１７は、電子機器を横方向複数取付する場合における機器側係止部と正方向・逆方向係止部との関係、及び押圧部材等の関係を示す概略説明図である。図１８は、本発明の実施形態の電子機器の取付け構造であって逆方向装着したものを背面側から見た背面図である。
【００８５】
本実施形態の電子機器取付け構造によって電子機器２を横方向複数取付する場合は、電子機器取付け装置５を逆方向装着する。
より具体的には、本体部８５を１８０度回転して裏返し、先とは反対側の開口を先頭にして電子機器の後端側に装着する。
すなわち電子機器取付け装置５の本体部８５は、略長方形の枠状であり、前後方向が連通開口するから、裏返して前後を逆にしても電子機器２の後端側に装着することができる。
【００８６】
前記した正方向装着姿勢では、図１，８，９に示すように、短辺を構成する壁部７１，７３に設けられた正方向押圧部材８１，８３がパネル６と当接する様な取付け姿勢で電子機器取付け装置５を電子機器２の後端側に装着したが、逆方向装着においては図１３，１６，１７に示すように長辺を構成する壁部７０，７２に設けられた逆方向押圧部材８０，８２がパネル６と当接する様な取付け姿勢で電子機器取付け装置５を電子機器２の後端側に装着する。
その結果、開口９０の前側においては、係合部形成部材３のフランジ部６１が開口９０の前側の長辺状縁部９３と当接し、開口９０の裏側においては、逆方向押圧部材８０，８２が開口９０の裏側の横辺の縁と当接し、フランジ部６１と電子機器取付け装置５によって長孔状の開口９０の縁を挟み込む。
【００８７】
電子機器取付け装置５を逆方向に取付けた状態では、同じく長辺を構成する壁部７０，７２に設けられた第二方向用係合部８６，８８が係合部形成部材３の長辺を構成する壁部３０，３２に設けられた機器側係合面３８，４２と係合する。
すなわち前記した様に、機器側係合部を構成する機器側係合面３８，４０，４２，４４は、後方側から見て、各壁部３０，３１，３２，３３の中心線上よりも反時計方向の位置にあるのに対し、電子機器取付け装置５側の係合部は、一方の開口側から観察したとき、手前側の開口近傍に設けられた係合部が、常に反時計方向の位置に有る。
【００８８】
そのため長辺を構成する壁部７０，７２に設けられた逆方向押圧部材８０，８２がパネル６と当接する様な取付け姿勢で電子機器取付け装置５を電子機器２の後端側に装着すると、図１７に示すように、必然的に第二方向用係合部８６，８８の位置が、電子機器２の長辺側に形成された機器側係合面３８，４２の位置と一致する。
従って、逆方向押圧部材８０，８２がパネル６と当接する様な取付け姿勢で電子機器取付け装置５を電子機器２の後端側に装着すると、電子機器取付け装置５の第二方向用係合部８６，８８が、機器側係合面３８，４２と係合する。
【００８９】
一方、逆方向取付け姿勢をとった場合、先の場合とは逆に、第一方向用係合部８７，８９は、後端側から見て、時計方向の位置に偏心した位置に来ることとなる。そのため係合部形成部材３の短辺を構成する壁部３１，３３に設けられた係合部形成片３５，３７の平坦な非係合面４１，４５が第一方向用係合部８７，８９と合致する。
係合部形成片３５，３７の非係合面４１，４５は平面状であるから、逆方向装着の際に第一方向用係合部８７，８９は機器側係合部と接触せず、係合しない。
従って本実施形態では、正方向装着の場合は、第一方向用係合部８７，８９だけが機器側の係合面と係合し、逆方向装着の場合は、第二方向用係合部８６，８８だけが機器側の係合面と係合する。
【００９０】
見方を変えて説明すると、正方向装着と逆方向装着の関係は、係合部形成部材３の特定の壁部３０，３１，３２，３３と面する電子機器取付け装置５の壁部７０，７１，７２，７３が、対向する長辺同士又は対向する短辺同士の間で入れ代わるか、あるいは壁部７０，７１，７２，７３自体が裏返る関係にある。
例えば長方形枠状の本体部８５を１８０度回転して裏返す際、図５の実線の矢印Ｂの様に短辺の中心を回転軸として回転する場合と、破線の矢印Ｂの様に長編の中心を回転軸として回転する場合がある。この時、例えば前者の短辺の中心を回転軸とする場合を考えると、長辺側の壁部７０，７２が入れ代わり、短辺側の壁部７１，７３はそれ自体が裏返ることとなる。逆に後者の長辺の中心を回転軸とする場合を考えると、短辺側の壁部７１，７３が入れ代わり、長辺側の壁部７０，７２はそれ自体が裏返る。
【００９１】
ここで各機器側係合面３８，４０，４２，４４についても係合部８６，８７，８８，８９についても、対向壁に設けられた係合部の位置は点対称であるから、両者が係合し合う位置についても点対称となる。そのため対向する長辺同士又は対向する短辺同士の間で入れ代わった場合は、新たに位置する係合部８６，８７，８８，８９の位置に機器側係合面３８，４０，４２，４４は無い。
同様に、壁部３０，３１，３２，３３に設けられた係合面３８，４０，４２，４４及び係合部８６，８７，８８，８９は、いずれも偏心した位置にあるから、壁部７０，７１，７２，７３自体が裏返った場合であっても新たに位置する係合部８６，８７，８８，８９の位置に機器側係合面３８，４０，４２，４４は無い。
従って前記した様に、本実施形態では、正方向装着の場合は、第一方向用係合部８７，８９だけが機器側係合面４０，４４と係合し、逆方向装着の場合は、第二方向用係合部８６，８８だけが機器側係合面３８，４２と係合する。
【００９２】
逆方向装着においても、先の正方向装着の場合と同様、第二方向用係合部８６，８８と、機器側係合面３８，４２との係合により、電子機器取付け装置５の後端側への移動は阻止されている。また逆方向押圧部材８０，８２は、弾性を有し、その押圧力によって第二方向用係合部８６，８８は機器側係合部３８，４２に押圧され、両者の間の遊びが消える。
【００９３】
逆方向装着の際の取付けの際の作業性は、正方向装着と同一であり、電子機器取付け装置５を電子機器２の後端側に装着せんとして電子機器取付け装置５を前方側に押すと、第二方向用係合部８６，８８のノッチに機器側係合面３８，４２のギザに乗り上げる方向の分力が発生し、係合片７５，７７が外側に撓んで機器側係合面３８，４２のギザを次々に乗り越えてゆく。
【００９４】
逆方向装着においても、逆方向押圧部材８０，８２と機器側係合部３９，４３によってラチェット状の逆転阻止構造が形成されている。そのため本実施形態では、電子機器取付け装置の装着に大きな力を要せず、且つ強固に後退を阻止する。
【００９５】
電子機器を横方向複数取付した場合の様子は、図１５，１６の通りであり、横長の長孔状開口９０に５個の電子機器２が並べて挿入され、各電子機器の正面部は開口９０の前面に位置する。
そして長孔状の開口９０の前面側では、隣接する係合部形成部材３のフランジ部６１同士が互いに接している。従ってパネル６を正面側から見ると、電子機器２が横に隙間無く並んだ状態で取付けられている。
また長孔状開口９０の裏面側では、開口９０の対向した長辺を構成する長辺状縁部９３（図１３，１４参照）の裏面部に逆方向押圧部材８０，８２の一部が接している。
【００９６】
一旦取付けた電子機器２をパネル６から取り外す場合は、第一方向係合片７６，７８又は第二方向係合片７５，７７を手で押し広げ、これらの係合を解いて電子機器取付け装置５を外すことにより行なうが、本実施形態では、取り外しを容易にするための工夫も凝らされている。
すなわち本実施形態では、いずれの場合でも、二つの第一方向係合片７６，７８又は第二方向係合片７５，７７を押し広げることによって係合を解くことができる。このように二つの係合片を押し広げるには、片方の手で片方の係合片を操作し、他方の手で残るもう一つの係合片を操作すれば良い。そのため本実施形態によると、特殊な治具や工具を要せずに電子機器２を取り外すことができる。
【００９７】
また本実施形態では、各係合片７５，７６，７７，７８に係合部８６，８７，８８，８９が設けられているが、係合部８６，８７，８８，８９の幅は、係合片７５，７６，７７，７８の幅の半分程度しかなく、係合部８６，８７，８８，８９は、係合片７５，７６，７７，７８に比べて小さい。
【００９８】
また機器側では、各係合部形成片３４，３５，３６，３７の機器側係合面３８，４０，４２，４４に隣接して、平面状の非係合面３９，４１，４３，４５が設けられている。
そのため各係合片７５，７６，７７，７８（電子機器取付け装置５側）の係合部８６，８７，８８，８９が機器側係合面３８，４０，４２，４４と係合するとき、各係合片７５，７６，７７，７８の平坦部分（係合部以外の部分）と、機器側の係合部形成辺３４，３５，３６，３７の平面状の非係合面３９，４１，４３，４５が向き合う。
【００９９】
そして非係合面３９，４１，４３，４５に隣接する機器側係合面３８，４０，４２，４４は、係合片７５，７６，７７，７８と係合しているから、前記した各係合片７５，７６，７７，７８の平坦部分（電子機器取付け装置５側）と、係合部形成片３４，３５，３６，３７の平面状の非係合面３９，４１，４３，４５（係合部形成部材３側）の間には僅かに隙間９５（図１８参照）ができる。そのため作業者は、当該隙間９５に爪を挟み、係合片７５，７６，７７，７８を容易に開くことができる。
【０１００】
また本実施形態では、係合片７５，７６，７７，７８の開放端が図５（ｂ）の様にやや外側に曲がった様な形状となっており、開放端の隙間が広いので、爪を挟む作業が更に容易である。
さらにまた係合片７５，７６，７７，７８は、壁部７０，７１，７２，７３の他の部分に比べて肉厚が薄く、撓みやすいので、係合片７５，７６，７７，７８を開くのに要する力も小さい。
【０１０１】
以上説明した実施形態では、機器側の係合部や、電子機器取付け装置側の係合部を偏心した位置に設けた。また機器側の対向する係合部や、電子機器取付け装置側の対向する係合部を点対称位置に設け、機器側と電子機器取付け装置側の係合位置が点対称となる様に設計した。
これは機器側の４辺に設けられた係合部と、電子機器取付け装置側の４辺に設けられた係合部からなる４組の係合組み合わせの内、特定の二組（２辺）だけを係合させ、他の二組（２辺）の係合を阻止するためであり、取付、取り外しが容易であって推奨すべき構成である。すなわち上記した構成によると、電子機器取付け装置の本体部の４辺の内、常に２辺だけが係合し、他の２辺は完全なフリー状態となる。
しかしながら本発明は、この実施形態に限定されるものではなく、図１９に示すように機器の係合部と電子機器取付け装置側の係合部を共に壁部の中央に設けてもよい。
【０１０２】
ここで図１９は、本発明の他の実施形態を示すものであり、電子機器２を縦方向複数取付する場合における機器側係止部と正方向・逆方向係止部との関係、及び押圧部材等の関係を示す概略説明図である。また図２０は、図１９の実施形態における、第二方向用係合部と機器側係合面との関係を示す要部拡大断面図である。
この様に両者を壁部の中央に設けると、全ての機器側係合面３８，４０，４２，４４と係合部８６，８７，８８，８９が接触することとなる。しかしながら、例えば、電子機器取付け装置側の係合部８６，８７，８８，８９の形状を先の実施形態と同様にするならば、係合させるべき組み合わせのもの以外は、実質的に係合しない。
【０１０３】
すなわち電子機器取付け装置側の係合部８６，８７，８８，８９は、図５（ｂ）の様な断面形状が３角状をした一山のノッチであり、根元側の傾斜面９２が緩く、開放側の傾斜面９１が急である。従って、図１９に示す様に機器の係合部と電子機器取付け装置側の係合部を共に壁部の中央に設け、正方向装着を行なう場合を想定すると、長辺を構成する壁部に設けられた係合部８６，８８は、急傾斜の傾斜面９１を先頭にして電子機器２側に進む。しかし対する電子機器２側の機器側係合面３８，４０，４２，４４は、進行方向に順目であるから、電子機器取付け装置５を装着する際に、係合部同士が係合することはなく、装着作業に支障はない。
【０１０４】
一方、電子機器取付け装置を抜き取る場合を想定すると、電子機器取付け装置を抜き取る場合、係止片７５，７７の係合部８６，８８は、図２０に示すように根元側の緩やかな傾斜面９２を先頭にして進むので、当該傾斜に沿って係止片７５，７７を開く方向の分力が生じ、電子機器取付け装置５を引き抜くことができる。
図１９に示す構成は、電子機器取付け装置を抜くときに多少の力はいるものの、実用上十分な機能を持つ。なお図１９に示す構成は、請求項３の技術範囲に含まれるものである。
【０１０５】
また上記した電子機器取付け装置は、いずれも押圧部材を本体と一体に成形したが、これを別体のものとしたり、形状等を変形することもできる。
図２１乃至２５は、本発明の他の実施形態であり、押圧部材の変形例を示す概略斜視図である
すなわち上記した電子機器取付け装置は、いずれも押圧部材を本体と一体に成形したが、図２１の様に本体部９６と押圧部９７を別々に成形してもよい。また押圧部の形状、構造は任意であり、例えば図２２に示すような、波板状の押圧部９７や、図２３の様なクッション状の押圧部９７を採用してもよい。さらには図２４に示すように、ネジ９８をもって押圧力を発生させるものであってもよく、また上記したいずれかを適宜組み合わせたものであってもよい。
【０１０６】
また上記した実施形態では、電子機器取付け装置の端面にそれぞれ２箇所、押圧部材を設けたが、図２５の様に、端面の各辺に押圧部材を設けてもよい。
なお図１等に示した実施形態は、正方向装着と、逆方向装着によって、当接される他部材の位置が変わるものであるのに対し、図２５に示す実施形態は、当接する位置は変わらないが、押圧力の分布が変わるものである。
【０１０７】
また先の例では、ラチェット様の逆止機能を発揮させるために、電子機器側にギザ状の凹凸を設け、電子機器取付け装置側に一山のノッチを設けたが、図２６に示すように電子機器取付け装置側にギザ状の凹凸９４を設け、他方に一山のノッチ９９を設けてもよい。
すなわち図２６は、本発明の他の実施形態における機器側係止部と正方向・逆方向係止部との関係、及び押圧部材等の関係を示す概略説明図である。
【０１０８】
電子機器取付け装置の本体部を構成する枠の形状は、先の実施形態の様な長方形が最も推奨されるが、他の形状を否定するものではなく、例えば円や楕円に近い形状のものも考えられる。あるいは８角形といった多角形も採用可能である。さらにはゴム等の変形能が高い素材によって本体部を成形し、電子機器の形状に沿って変形する様な構成も考えられる。
【０１０９】
また上記した実施形態では、縦長又は横長の長孔状開口９０に複数の電子機器が並べて挿入するレイアウトを例に説明したが、もちろん一つの孔に一つの電子機器を装着する場合にも本発明を採用することができる。
上記した実施形態では、電子機器に係合部形成部材３を装着して機器側係合部を形成せしめたが、機器側係合部を電子機器の筐体に直接的に形成させてもよい。
【０１１０】
【発明の効果】
以上説明したように、本発明では、電子機器取付け装置のいずれの開口を先頭にして電子機器側に装着するかによってパネル部材に対する当接状態が変わる。そのため本発明の電子機器取付け構造は、取付レイアウトの自由度が高い。
また電子機器の縦横両方向への複数取付けを、単一構造の取付け装置を使用して行うこともでき、部品の互換性を高める効果がある。
特に請求項２に記載の発明は、電子機器側に複数の機器側係合部が設けられ、電子機器取付け装置には第一方向用係合部及び第二方向用係合部が設けられている。
そのため電子機器取付け装置のいずれの開口を先頭にして電子機器側に装着しても、電子機器取付け装置を電子機器側にしっかりと固定することができる効果がある。
請求項３に記載の発明についても、電子機器取付け装置を電子機器側にしっかりと固定することができる効果がある。
また請求項４，５に記載の発明は、電子機器取付け装置の着脱が容易であるという効果がある。
【０１１１】
また請求項６に記載の発明は、正方向装着による場合と、逆方向装着による場合で電子機器取付け装置が当接する位置が異なるので、縦横両方向への複数取付けを、単一構造の取付け装置を使用して確実に行うことができる効果がある。
【０１１２】
また請求項７に記載の発明は、押圧部材を有し、押圧部材によって第一方向用係合部はより直接的に機器側係合部に押圧され、両者の間の遊びを無くす。そのため本発明の電子機器取付構造は、取付強度が高い効果がある。
【０１１３】
また請求項８に記載の発明は、電子機器を縦又は横に並べた時、隣接する押圧部材同士が干渉することがなく、使いやすいという効果がある。
【０１１４】
また請求項９に記載の発明は、具体的に縦方向複数取付や横方向複数取付けを行った場合の構成を開示するものであり、実用性が高い効果がある。
【０１１５】
また請求項１０，１１，１２に記載の発明は、電子機器取付け装置に関するものであり、上記した請求項１と同様の効果がある。

On the other hand, the first direction engaging portions 87, 89 of the electronic device mounting device 5 are located on the same wall portions 71, 73 as the forward direction pressing members 81, 83, and are provided on the opposite side to the forward direction pressing members 81, 83. At the end. As described above, since the electronic device mounting device 5 is mounted in a posture in which the forward direction pressing members 81 and 83 abut the panel 6, the first direction engaging portions 87 and 89 are located at positions away from the panel 6. .
[0073]
On the other hand, as described above, the engaging portions 86, 87, 88, and 89 of the electronic device mounting apparatus 5 have the engaging portions 86, 87, and 78 with the open sides of the engaging pieces 75, 76, 77, and 78 facing upward.

That is, the second-direction engaging portions 86 and 88 do not come into contact with the device-side engaging portions and do not engage during the forward mounting.
The engagement of the first-direction engaging portions 87 and 89 with the device-side engaging surfaces 40 and 44 in this manner prevents the electronic device mounting device 5 from moving to the rear end side. Since the forward direction pressing members 81 and 83 are members having elasticity, the first direction engaging portions 87 and 89 are pressed against the device side engaging portions 40 and 44 by the pressing force of the forward direction pressing members 81 and 83. And the play between them disappears.
[0076]
That is, since the forward direction pressing members 81 and 83 are arcuate and elastic, the electronic device mounting device 5 is urged rearward when the forward direction pressing members 81 and 83 come into contact with the rear surface of the panel 6. The play between the two is eliminated, and the rattling is eliminated. In particular, in the present embodiment, since the positive direction pressing members 81 and 83 are provided on the same side as the side where the first direction engaging portions 87 and 89 are provided, the pressing force of the positive direction pressing members 81 and 83 is provided. Directly engages the first direction engaging portions 87 and 89. Therefore, in the present embodiment, the first-direction engaging members 87 and 89 are more directly pressed by the device-side engaging members by the forward-direction pressing members 81 and 83, and have a strong effect of eliminating play between them.
[0077]
Further, in the present embodiment, the forward direction pressing members 81 and 83 are provided on one opening side of the side constituting the electronic device mounting apparatus 5 and the first direction engaging portions 87 and 89 are provided on the other opening side.
