Description

【０００１】
【発明の属する技術分野】
この発明は、操作盤の開閉構造に関し、特に背板を有しこの背板を覆う筐体の開閉構造についての操作盤に関するものである。
【０００２】
【従来の技術】
この発明における従来の操作盤は、背板と、この背板の前面を覆う箱状の筐体とで構成され、かつ、背板の前面に搭載された各種部品と、筐体に取り付けられたディスプレー装置や操作スイッチなどの多数の部品とは、背板と筐体の内側に亘る配線束によりそれぞれ接続されて構成されている。そして、背板に形成された取り付け機構により壁面などに取り付けられている。
【０００３】
操作盤は点検や設定変更等により時折筐体を開く必要があるが、筐体と背板とに亘る上記配線束があるため、背板と筐体は分離できずに蝶番で連結されており、背板と筐体とは、別途ねじなどの固定手段で閉止固定している。
【０００４】
【発明が解決しようとする課題】
このような操作盤は、通常の状態つまり筐体を閉じた状態では、背板の縁が外面から見えるので、また蝶番を外側で連結した場合にはその蝶番が見えるので、これが目障りなため、蝶番を内部に配置するとともに背板の縁の全周を筐体で囲って隠すことが考えられる。
【０００５】
しかし、背板の縁の全周を筐体で囲って隠した上で、操作盤内部の蝶番により筐体を開こうとすると、筐体の蝶番側の縁と背板の取り付け壁面、及び筐体の蝶番側の縁と背板の蝶番側の縁が互いに干渉して衝突し合うため、筐体の蝶番側の縁に壁面に対する逃げ寸法あるいは背板の蝶番側の縁に筐体に対する逃げ寸法をとる必要があった。その結果、その筐体の逃げ寸法がそのまま筐体を閉じた状態における外観上の隙間となってしまい、背板の縁の全周を覆い隠すことができないばかりか、この両方の逃げ寸法すなわち隙間がほこりなど異物が操作盤に侵入するのを許してしまい不具合であった。
【０００６】
従って、背板と内部の蝶番で連結した箱状の筐体を持つ操作盤は、背板の縁の全周囲を囲うような構造を採ることは出来なかった。
【０００７】
【課題を解決するための手段】
この発明は、壁面に取り付けられ、端部に延出部が設けられた背板と、この背板の前面を覆い、前記背板の延出部部分を延出部の板厚で切り欠いた切欠凹部と該切欠凹部以外の切り欠き残された筐体端部とを側板に有する筐体と、前記筐体を回動可能に前記背板と前記筐体とを連結する蝶番であって、前記筐体の側板の内側の切欠凹部近傍に固定された第１の蝶番板と前記背板の前面の延出部近傍に取り付けられた第２の蝶番板とを有し、前記側板の切欠凹部の外縁が前記延出部の上面を摺動することにより、前記筐体を前記背板に対して回動させる蝶番と、前記背板と前記筐体とを閉止状態に保持する固定手段と、で構成され、前記筐体が、前記筐体の閉止状態で、前記延出部を除いて前記背板の縁の全周を前記壁面との間の隙間が無い状態で覆い隠す操作盤であって、前記蝶番は、前記第２の蝶番板のねじ孔を前記背板に垂直に立てられたビスに挿通したものであって、前記筐体の開放過程で前記筐体が前記壁面に干渉しないように、前記ビスへのナットの固定位置によって、前記第２の蝶番板に前記背板の板厚方向に遊びを設けたものであり、前記背板は、前記筐体を全開させるとき、前記側板の筐体端部の縁に衝突することのない位置に、前記蝶番側の縁が退いて設けられているものであることを特徴としている。
【０００８】
また、前記背板と前記第２の蝶番板との間に、前記筐体を開く過程で前記筐体を押し上げる弾性体を介在させたことを特徴としている。
【０００９】
【発明の実施の形態】
実施の形態１．
図１は操作盤の閉止状態の外観を示す斜視図である。図２は操作盤の開閉過程を蝶番部において示した要部拡大縦断面図であり、（ａ）は閉止状態、（ｂ）は開け始めの状態、（ｃ）は蝶番の最高リフトの状態、（ｄ）は全開状態をそれぞれ示す。
【００１０】
図１及び図２により以下に実施の形態１の構成を説明する。
Ｗは壁面、１は壁面Ｗに取りつけられた操作盤、１１は矩形であって例えば四隅端部が部分的に延出したＨ字状の背板、１１ａは背板１１の前記部分的に延出させ壁面取付部とした各延出部、１１ｄは背板１１の縁、１１ｅは縁１１ｄの前方側の縁線である背板前縁、１１ｓは延出部１１ａの前方側の面である上面である。
【００１１】
１２は背板１１の延出部１１ａ部分を延出部１１ａの板厚で切り欠き、延出部１１ａを除いて背板１１の縁の全周を覆う筐体、１２ａは筐体１２の延出部１１ａ側の側板、１２ｂは側板１２ａであって背板１１の延出部１１ａ部分を延出部１１ａの板厚で切り欠き残された筐体端部、１２ｄは筐体端部１２ｂの縁であり、延出部１１ａにおける縦断面図である図２の（ｄ）に示されるように、筐体１２の全開時に背板１１の縁１１ｄは縁１２ｄに衝突することのない位置に設けられている。１２ｐは、筐体１２を開くとき側板１２ａが延出部１１ａの上面１１ｓと摺動する、筐体１２の上記切り欠きの切欠凹部外縁、１２ｒは縁１２ｄの下端内縁、１２ｑは縁１２ｄの下端外縁である。
【００１２】
筐体１２の閉止時には、後述するように、ねじなどの固定手段１７で筐体１２と背板１１とが固定されているため、切欠凹部外縁１２ｐと上面１１ｓの間及び下端外縁１２ｑと壁面Ｗの間の隙間はなくなる。
【００１３】
１３は背板１１の前面と側板１２ａの内側とで連結する、すなわち操作盤１の内部に取りつけられた蝶番、１３ａは側板１２ａ側に固定された蝶番１３の第１の蝶番板、１３ｂは背板１１側に取りつけられた蝶番１３の第２の蝶番板である。
【００１４】
図２において、１４は背板１１に垂直に立てられ蝶番板１３ｂの図示しないねじ孔に挿通するビス、１５はこのビス１４に螺入し所定の位置で接着固定したナット、Ｃは蝶番１３の軸芯である。
【００１５】
このナット１５の所定の位置は図２（ｃ）に示されるように、筐体１２の開放過程において蝶番１３が最も高くリフトされた時の高さが得られる位置以上の高さに固定される。例えば、筐体１２を開いていく際、蝶番１３の高さを決定するのは側板１２の背板１１（延出部１１ａ）との摺動点である切欠凹部外縁１２ｐの位置であり、この点１２ｐの位置が蝶番１３の軸芯Ｃの真下に来たとき蝶番１３の軸芯Ｃの高さが最も高く（最も背板１１から離れる）ことになり、それが可能な位置、例えば最高軸芯Ｃ位置において蝶番板１３ｂを背板１１に平行にしたときの高さに合わせてナット１５の位置を決め、蝶番板１３ｂに蝶番板１３ｂの板厚方向の遊びＦを設けて、ナット１５を金属接着剤等で固定する。
【００１６】
次に図２によって動作を説明する。
（ａ）の状態では、筐体１２は背板１１とねじなどの固定手段１７で蝶番の遊びＦ１によるがたつきがないように固定閉止されており、操作盤１が壁面Ｗに延出部１１を介して取りつけられた状態である。この時、背板１１の縁１１ｄは延出部１１ａを除いて全周が筐体１２にて覆い隠され、すなわち筐体１２が囲う背板１１の縁の全周が覆い隠されている。言いかえると、蝶番１３の近くの筐体端縁１２ｂによって壁面Ｗとの間の隙間がない状態で縁１１ｄが覆いかくされ、かつ延出部１１ａの上面１１ｓと切欠凹部外縁１２ｐとの間も隙間がない状態である。
【００１７】
背板１１と筐体１２との固定手段１７による固定は、どの位置で行ってもよいが、蝶番１３の遊びＦ１による筐体１２のがたつきがないように固定されている。
【００１８】
従って、美観は保たれ、ほこりなど異物が入らない。
【００１９】
次に、保守点検や設定変更など必要に応じて、壁面Ｗに取りつけられた操作盤１の筐体と背板との固定手段１７を解除する。
【００２０】
そして図２の（ｂ）のように、筐体１２が背板１１から自由にされてから筐体１２を開け始めると、切欠凹部外縁１２ｐが延出部１１ａの上面１１ｓを摺動していく。この時この下の下端外縁１２ｑは、側板１２ａが傾くので壁面Ｗに対して摺動することはない。
【００２１】
すると図２の（ｃ）に示されるように、蝶番１３の軸芯Ｃの高さは切欠凹部外縁１２ｐの摺動時の位置によって決定され、切欠凹部外縁１２ｐが軸芯Ｃの真下に位置するとき最も高く、すなわち軸芯Ｃと切欠凹部外縁１２ｐの距離だけリフトされる。ナット１５はそのときの位置に対応可能な高さに位置して固定されており、筐体１２の動きを妨げない。
【００２２】
その後、図２の（ｄ）に示すように、筐体１２を全開させるとき、背板１１の縁１１ｄが側板１２ａの縁１２ｄに衝突することのない位置に退いて逃げ寸法をとっているので、筐体１２の全開を妨げることはない。縁１１ｄが縁１２ｄに衝突しないためには、軸芯Ｃと背板前縁１１ｅとの距離が軸芯Ｃと下端外縁１２ｑとの距離よりも大きく設定するとよい。
【００２３】
筐体１２の閉止の際は、上記の逆の行程を踏み、筐体１２は壁面Ｗとの間で隙間なく閉止することができる。
【００２４】
なお、上記実施の形態では、筐体１２を閉止した状態における背板１１の縁１１ｄと側板１２ａとの水平距離すなわち逃げ寸法を、筐体１２の全開状態における側板１２ａの縁１２ｄの入り込む量だけとって、背板１１の縁１１ｄを後退して形成したが、これを、より小さな逃げ寸法に構成してもよい。この場合、側板１２ａと背板１１の衝突を回避するよう、背板前縁１２ｑの回動軌跡が背板前縁１１ｅと干渉しないようにナット１５の高さを高く設定する。筐体１２を開くときは、筐体１２を十分に持ち上げてから開くようにすると、ナット１５の高さが十分高く設定されているので背板前縁１２ｑが背板前縁１１ｅとの衝突を回避できるため、筐体１２を全開にすることができる。
【００２５】
上記逃げの寸法をゼロに選んでもよい。すると筐体端部１２ｂと背板１１の縁１１ｄとは、筐体１２の閉止状態で当接する構成となる。この場合上記と同様の方法でナット１５の高さを十分高く設定する。筐体１２を開くときは、まず筐体１２を十分に持ち上げてから開くようにすると、ナット１５の高さが十分高く設定されているので、筐体１２を全開にすることができる。
【００２６】
ところで、このように構成することによって、単に固定手段１７を外しても、筐体端部１２ｂと縁１１ｄとが衝突して開くことが出来ないので、一般の人が不要に開けることのないような構成となっている。
【００２７】
このような逃げ寸法が小さい場合の蝶番１３の背板１１の板厚方向への必要な遊びＦ１寸法は次のように決める。
【００２８】
図２（ｃ）に示されるように、ナット１５の位置は、筐体１２の開放過程において、蝶番１３軸芯Ｃからの距離が、筐体端部１２ｂで最も遠い下端外縁１２ｑと、背板１１の縁１１ｄで最も近い背板前縁１１ｅとを比べ、背板前縁１１ｅの方が長くなるように、側板１２ａ及び蝶番１３をリフトしたときの高さ位置に決める。このように蝶番板１３ｂに背板１１の板厚方向の遊びＦ１を設けるようにして、ナット１５の位置を決めた後、ナット１５を金属接着剤等で固定する。
【００２９】
以上のように、実施の形態１では、壁面に取り付けられる背板と、この背板の前面を覆う筐体と、筐体を回動可能に背板と筐体とを連結する連結具と、背板と筐体とを閉止状態に保持する固定手段とで構成される操作盤において、連結具を操作盤の内側に取り付け、筐体の閉止状態で筐体が囲う範囲の背板の縁の全周を筐体が覆い隠し、筐体の開放過程で筐体が背板および壁面に干渉しないよう連結具に遊びを設けるようにしたので、筐体を開く過程で、連結具の遊びを利用して筐体を浮かせることができるため、筐体の下端が壁面に衝突することなく筐体を開放させることが出来、また、連結具の遊びを利用して筐体を持ち上げて筐体と背板の衝突を回避できるため、筐体を開放させることが出来、また、連結具を操作盤の内側に取り付け、筐体が囲う範囲の背板の縁の全周を筐体が隙間なく覆い隠すため美観が保たれ、異物も入ることがないので信頼性の高い操作盤が得られる。
【００３０】
実施の形態２．
実施の形態１では背板１１に延出部１１ａを設けていたが、実施の形態２では延出部１１ａのない単なる矩形の背板を用いる。この場合は、延出部１１ａと上面１１ｓと切欠凹部外縁１２ｐが存在せず、他の符号は実施の形態１と同一の符号が用いられる。また、筐体１２を全開したとき側板１２ａが載置されるのは、上面１１ｓの代わりに壁面Ｗとなる。但し、側板１２ａが背板１１よりも薄ければ、側板１２ａは壁面Ｗに載置されずに少し浮く格好になる。
【００３１】
筐体１２を開く際、側板１２ａと壁面Ｗの衝突を回避するよう、背板前縁１２ｑの回動軌跡が壁面Ｗと干渉しないように、ナット１５の高さを高く設定する。すなわち、ナット１５の高さ位置は、蝶番１３を壁面Ｗから最も高く持ち上げた時の高さを、蝶番１３軸芯Ｃと下端外縁１２ｑとの距離よりも大きくできるように決める。
【００３２】
また、筐体１２を閉止した状態における背板１１の縁１１ｄと側板１２ａとの水平距離すなわち逃げ寸法を、筐体１２の全開状態における側板１２ａの縁１２ｄの入り込む量だけとって、背板１１の縁１１ｄを後退して形成する。すなわち、蝶番１３の軸芯Ｃと下端内縁１２ｒとの距離よりも、軸芯Ｃと背板前縁１１ｅとの距離の方が長くなるように形成する。
【００３３】
筐体１２を開くときは、ナット１５の高さが高く設定されているので蝶番１３が背板１１の板厚方向に逃げることができ、背板前縁１２ｑが壁面Ｗの上を摺動しながら開くことができる。背板１１の縁１１ｄは側板１２の縁１２ｄに対する逃げ寸法をとっているので、筐体１２を全開にすることができる。
【００３４】
なお、矩形の背板において、上記のような縁１１ｄの縁１２ｄに対する逃げ寸法をゼロにしてもよい。この場合は、筐体１２を全開したとき側板１２ａが載置されるのは、壁面Ｗの代わりに背板１１の上面となり、その他は実施の形態１における延出部１１ａのある場合の逃げ寸法ゼロの場合と同様である。
【００３５】
また、上記実施の形態１，２では、連結具の遊びを、背板１１に垂直に立てられたビス１４に蝶番板１３ｂを挿通させ、ナット１５の位置にて作っていたが、これを背板１１側の蝶番板１３ｂを固定し、測板１２ａ側の蝶番板１３ａのビス孔を背板１１の板厚方向に長孔に形成して遊びを作ってもよい。
【００３６】
また、上記実施の形態１，２では連結具として蝶番を用いたが、チェーンやリンク機構を用いてもよい。
【００３７】
実施の形態３．
図３は操作盤の全開状態の内部構造を示す説明図であり、一部の蝶番を取り除いた状態を示した説明図である。図４は操作盤の開閉過程を蝶番部において示した要部拡大縦断面図であり、（ａ）は閉止状態、（ｂ）は半開状態、（ｃ）は全開状態をそれぞれ示す。
【００３８】
図３及び図４により以下に実施の形態２の構成を説明する。
Ｗは壁面、２は壁面Ｗに取りつけられた操作盤、２１は矩形であって例えば四隅端部が部分的に延出したＨ字状の背板、２１ａは背板２１の前記部分的に延出させ壁面取付部とした各延出部、２１ｄは背板２１の縁、２１ｅは縁２１ｄの前方側の縁線である背板前縁、２１ｓは延出部２１ａの上面である。
【００３９】
２２は背板２１の延出部２１ａ部分を延出部２１ａの板厚で切り欠き、延出部２１ａを除いて背板２１の縁の全周を覆う筐体、２２ａは筐体２２の延出部２１ａ側の側板、２２ｂは側板２２ａであって背板２１の延出部２１ａ部分を延出部２１ａの板厚で切り欠き残された筐体端部、２２ｄは筐体端部２２ｂの縁であり、延出部２１ａのない背板２１の部分における縦断面図である図４の（ｂ）に示されるように、筐体２２の開放過程において背板２１の縁２１ｄは、側板２２ａを蝶番２３と共に持ち上げることにより、縁２２ｄが縁２１ｄをかわすことのできる位置に設けられている。２２ｐは筐体２が閉じているとき延出部２１ａの上面２１ｓに当接する側板２２ａの切欠凹部外縁であり、閉止時には後述するように図示しないねじなどの固定手段で筐体２２と背板２１とが固定されているため、上面２１ｓと切欠凹部外縁２２ｐの間の隙間はないようにしてある。
【００４０】
２３は背板２１の前面と側板２２ａの内側とで連結する、すなわち操作盤２の内部に取りつけられた蝶番であり、例えば市販のものを使用する。２３ａは側板２２ａ側に固定された蝶番２３の第１の蝶番板、２３ｂは背板２１側に取りつけられた蝶番２３の第２の蝶番板である。
【００４１】
２４は背板２１に垂直に立てられ蝶番２３の第２の板２３ｂの図示しないねじ孔に挿通するビス、２５はこのビス２４に螺入し所定の位置で接着固定されたナット、２６は背板２１と蝶番板２３ｂとの間に、例えばビス２５に貫通されて介在される弾性体、例えば弦巻バネや復元力の強いスポンジあるいはゴムの形成体などである。２７は背板２１に形成されたビス２４の挿通孔、Ｃは蝶番２３の軸芯である。
【００４２】
図４の（ａ）に示されるように、Ｌ１は筐体２２の閉止した状態における軸芯Ｃから側板２２ａの縁２２ｄまでの垂直距離、Ｌ２は筐体２２の閉止した状態における軸芯Ｃから背板２１の縁２１ｄまでの水平距離を示す。この距離Ｌ２がＬ１以上ならば、筐体２２の全開時に縁２２ｄは縁２１ｄに衝突することはない。
【００４３】
しかし、蝶番２３に市販品を用いれば背板２１の板厚の関係で、距離Ｌ２がＬ１未満のことがある。この場合は側板２２ａを蝶番２３と共に持ち上げて、上方に逃げ、縁２２ｄと縁２１ｄの衝突をかわす方法をとる。上方に逃げる際、蝶番２３を規制するナット２５の高さ位置を決める必要がある。
【００４４】
図４の（ｂ）に示されるように、ナット２５の所定の位置は、筐体２２の開放過程において、蝶番２３軸芯Ｃからの距離が、筐体端部２２ｂで最も遠い下端外縁２２ｑと、背板２１の縁２１ｄで最も近い背板前縁２１ｅとを比べ、背板前縁２１ｅの方が長くなるように、側板２２ａ及び蝶番２３をリフトしたときの高さ位置にナット２５が固定される。このように蝶番板２３ｂに板厚方向の遊びＦ２を設けるようにして、ナット２５の位置を決めた後、ナット２５を金属接着剤等で固定する。
【００４５】
次に図４によって動作を説明する。
（ａ）の状態では筐体２２は背板２１を図示しない固定手段で蝶番２３の遊びＦ２によるがたつきがないように固定閉止されており、例えば操作盤２が壁面Ｗなどに延出部２１ａで取りつけられた状態である。この時、背板２１の縁２１ｄは延出部２１ａを除いて全周が筐体２２にて覆い隠されて、蝶番２３の近くの筐体端縁２２ｂによっても壁面Ｗとの間の隙間がない状態で縁２１ｄは覆い隠され、かつ延出部２１ａの上面２１ｓと切欠凹部外縁２２ｐとの間も隙間がない状態である。従って通常時においては、美観は保たれ、ほこりなど異物が入らない。
【００４６】
次に、保守点検などの必要に応じて、壁面Ｗに取り付けられた操作盤２の図示しない固定手段を外し、筐体２２を背板２１から開くことができるようにする。
【００４７】
図４の（ｂ）に示すように筐体２２を開く過程で、筐体端部２２ｂの縁２２ｄが背板の縁２１ｄに引っ掛かりそうな時に、弾性体２６が蝶番板２３ｂを押し上げるので、また、ナット２５の高さ位置も十分に高く設定されているため、容易にかわすことができる。
【００４８】
図４の（ｃ）に示すように、その後、側板２２ａが延出部２１ａの上面２１ｓに重ねられ、筐体端部２２ｂは背板２１の上に重ねられ、筐体２２が９０度開いて全開する。
【００４９】
筐体２２の閉止の際は、上記の逆の行程を踏み、筐体２２を持ち上げて筐体端部２２ｂの縁２２ｄが背板２１の縁２１ｄをかわして筐体１２を閉じたあと、図示しない固定手段により筐体２２を背板２１に閉止固定する。この時、筐体２２が弾性体２６のために蝶番２３側が浮き上がる場合は、筐体２２を押圧して固定する。この閉止状態では、背板２１の縁２１ｄは延出部２１ａを除いて、筐体２２が囲う背板２１の縁２１ｄの全周が筐体２２にて覆い隠され、つまり筐体端縁２２ｂによって壁面Ｗとの間に隙間がない状態で縁２１ｄは覆い隠され、かつ延出部２１ａの上面２１ｓと切欠凹部外縁２２ｐとの間も隙間がない状態となる。
【００５０】
以上のような実施の形態３の構成により、壁面に取り付けられる背板と、この背板の前面を覆う箱状の筐体と、背板と筐体とを連結する蝶番と、背板と筐体とを閉止状態に保持する固定手段とで構成される操作盤において、蝶番が背板の前面と筐体の内側とで連結し、筐体の閉止状態で筐体が囲う範囲の背板の縁の全周を筐体が覆い隠し、背板側の蝶番板にはこの背板の板厚方向に遊びを設けるようにし、背板とこの背板側の蝶番板との間に弾性体を介在させたので、筐体が囲う範囲の背板の縁の全周や蝶番が外面から見えないため美観が保たれ、筐体が囲う背板の縁の全周を覆い隠すため異物も入ることがなく信頼性の高い操作盤が得られる。また、筐体を開く過程で筐体と背板の衝突を回避するために筐体を持ち上げる時に、弾性体により押し上げられるため、容易に開放させることが出来る。
【００５１】
また、筐体を開く過程で弾性体により筐体が押し上げられることから、実施形態１における延出部１１ａの上面１１ｓと筐体１２の切欠凹部外縁１２ｐのような摺動がなくなり、上面２１ｓなどの摺動面の塗装剥げ等の問題もなくなる。
【００５２】
なお、以上の実施の形態３では背板に延出部を設けていたが、単に矩形の背板であってもよい。
【００５３】
【発明の効果】
この発明にかかる操作盤の開閉構造は、壁面に取り付けられ、端部に延出部が設けられた背板と、この背板の前面を覆い、前記背板の延出部部分を延出部の板厚で切り欠いた切欠凹部と該切欠凹部以外の切り欠き残された筐体端部とを側板に有する筐体と、前記筐体を回動可能に前記背板と前記筐体とを連結する蝶番であって、前記筐体の側板の内側の切欠凹部近傍に固定された第１の蝶番板と前記背板の前面の延出部近傍に取り付けられた第２の蝶番板とを有し、前記側板の切欠凹部の外縁が前記延出部の上面を摺動することにより、前記筐体を前記背板に対して回動させる蝶番と、前記背板と前記筐体とを閉止状態に保持する固定手段と、で構成され、前記筐体が、前記筐体の閉止状態で、前記延出部を除いて前記背板の縁の全周を前記壁面との間の隙間が無い状態で覆い隠す操作盤であって、前記蝶番は、前記第２の蝶番板のねじ孔を前記背板に垂直に立てられたビスに挿通したものであって、前記筐体の開放過程で前記筐体が前記壁面に干渉しないように、前記ビスへのナットの固定位置によって、前記第２の蝶番板に前記背板の板厚方向に遊びを設けたものであり、前記背板は、前記筐体を全開させるとき、前記側板の筐体端部の縁に衝突することのない位置に、前記蝶番側の縁が退いて設けられているので、筐体が囲う背板の縁の全周や蝶番が外面から見えないため美観がよく、筐体が囲う背板の縁の全周を覆い隠すため異物も入ることがなく信頼性の高い操作盤が得られる。
また、筐体を開く過程で、蝶番の遊びを利用して筐体を浮かせることができるため、筐体の下端が壁面に衝突することなく筐体を開放させることが出来る。
また、筐体を全開させるとき、背板の縁が側板の縁に衝突することのない位置に退いて逃げ寸法をとっているので、筐体の全開を妨げることはない。
【００５４】
また、前記背板と前記第２の蝶番板との間に、前記筐体を開く過程で前記筐体を押し上げる弾性体を介在させた。これによって、筐体を開く過程で筐体と背板とが蝶番付近での衝突を回避するために筐体を持ち上げる時に、弾性体により筐体が押し上げられるため、容易に開くことが出来る操作盤が得られる。筐体を開く過程で弾性体により筐体が押し上げられることから、延出部の上面と筐体の切欠凹部外縁のような摺動がなくなり、上面などの摺動面の塗装剥げ等の問題もなくなる。

[0003]
The operation panel needs to be opened from time to time due to inspections, setting changes, etc., but because of the above-mentioned wiring bundle that spans the case and back plate, the back plate and case cannot be separated and are connected by a hinge. The back plate and the casing are closed and fixed separately by fixing means such as screws.
[0004]
[Problems to be solved by the invention]
In such an operation panel, the edge of the back plate can be seen from the outer surface in a normal state, that is, the case is closed, and when the hinge is connected on the outside, the hinge can be seen. It is conceivable that a hinge is disposed inside and the entire periphery of the edge of the back plate is enclosed by a casing and concealed.
[0005]
However, if the casing is opened by a hinge inside the operation panel after the entire periphery of the edge of the back plate is enclosed and hidden by the casing, the hinge on the hinge side of the casing, the mounting wall of the back plate, and the casing Because the hinge side edge of the body and the hinge side edge of the back plate interfere and collide with each other, the clearance dimension against the wall surface on the hinge side edge of the housing or the clearance size against the housing on the hinge side edge of the back plate It was necessary to take. As a result, the clearance dimension of the casing becomes a gap in appearance when the casing is closed as it is, and not only cannot the entire circumference of the edge of the back plate be obscured, but both clearance dimensions, that is, the clearance. It was a malfunction that allowed foreign objects such as dust to enter the operation panel.
[0006]
Therefore, an operation panel having a box-shaped housing connected to the back plate with an internal hinge cannot adopt a structure that surrounds the entire periphery of the back plate.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
FIG. 1 is a perspective view showing an external appearance of the operation panel in a closed state. FIG. 2 is an enlarged longitudinal sectional view of the main part showing the opening and closing process of the operation panel at the hinge part, where (a) is in a closed state, (b) is in a state of opening, (c) is in a state of maximum lift of the hinge, (D) shows a fully open state, respectively.
[0010]
The configuration of the first embodiment will be described below with reference to FIGS.
W is a wall surface, 1 is an operation panel attached to the wall surface W, 11 is rectangular, for example, an H-shaped back plate partially extending at the four corner ends, and 11a is a partially extended portion of the back plate 11. Each extending portion used as a wall surface attaching portion, 11d is an edge of the back plate 11, 11e is a front edge of the back plate which is an edge line on the front side of the edge 11d, and 11s is an upper surface which is a surface on the front side of the extending portion 11a. It is.
[0011]
12 is a housing that covers the entire periphery of the back plate 11 except for the extending portion 11a except for the extending portion 11a. The side plate on the protruding portion 11a side, 12b is the side plate 12a, and the extended portion 11a portion of the back plate 11 is left uncut by the plate thickness of the extended portion 11a, and 12d is the casing end portion 12b. As shown in FIG. 2D, which is a longitudinal sectional view of the extending portion 11a, the edge 11d of the back plate 11 is provided at a position where it does not collide with the edge 12d when the housing 12 is fully opened. It has been. 12p is the outer edge of the notch in the notch of the notch 12 in which the side plate 12a slides on the upper surface 11s of the extending portion 11a when the housing 12 is opened, 12r is the lower inner edge of the edge 12d, and 12q is the lower edge of the edge 12d. The outer edge.
[0012]
When the casing 12 is closed, as will be described later, the casing 12 and the back plate 11 are fixed by a fixing means 17 such as a screw. Therefore, between the outer edge 12p of the notch recess and the upper surface 11s, and the outer edge 12q of the lower end and the wall surface W. The gap between is gone.
[0013]
13 is connected to the front surface of the back plate 11 and the inside of the side plate 12a, that is, a hinge attached to the inside of the operation panel 1, 13a is a first hinge plate of the hinge 13 fixed to the side plate 12a side, and 13b is a back. It is the 2nd hinge board of the hinge 13 attached to the board 11 side.
[0014]
In FIG. 2, 14 is a screw that stands upright on the back plate 11 and passes through a screw hole (not shown) of the hinge plate 13b, 15 is a nut that is screwed into this screw 14 and bonded and fixed in place, and C is the hinge 13 It is a shaft core.
[0015]
As shown in FIG. 2C, the predetermined position of the nut 15 is fixed at a height higher than the position where the height when the hinge 13 is lifted to the highest level in the process of opening the housing 12 is obtained. . For example, when the housing 12 is opened, the height of the hinge 13 is determined by the position of the outer edge 12p of the notch recess that is the sliding point of the side plate 12 with the back plate 11 (extension portion 11a). When the position of the point 12p comes directly below the axis C of the hinge 13, the axis C of the hinge 13 has the highest height (the farthest away from the back plate 11), and a position where this is possible, for example, the highest axis The position of the nut 15 is determined in accordance with the height when the hinge plate 13b is parallel to the back plate 11 at the position of the core C, and a play F in the thickness direction of the hinge plate 13b is provided on the hinge plate 13b. Fix with metal adhesive.
[0016]
Next, the operation will be described with reference to FIG.
In the state of (a), the casing 12 is fixed and closed by the back plate 11 and fixing means 17 such as screws so that there is no rattling caused by the hinge play F1, and the operation panel 1 extends to the wall surface W. 11 is attached. At this time, the entire periphery of the edge 11d of the back plate 11 is covered with the housing 12 except for the extending portion 11a, that is, the entire periphery of the edge of the back plate 11 surrounded by the housing 12 is covered. In other words, the edge 11d is covered by the housing edge 12b near the hinge 13 without any gap between the wall surface W, and the space between the upper surface 11s of the extending portion 11a and the outer edge 12p of the notch recess is also between. There is no gap.
[0017]
The back plate 11 and the housing 12 may be fixed by the fixing means 17 at any position, but are fixed so that the housing 12 does not rattle due to the play F1 of the hinge 13.
[0018]
Therefore, the aesthetics are maintained and foreign matter such as dust does not enter.
[0019]
Next, the fixing means 17 between the casing and the back plate of the operation panel 1 attached to the wall surface W is released as necessary, such as maintenance inspection and setting change.
[0020]
Then, as shown in FIG. 2B, when the housing 12 starts to be opened after the housing 12 is released from the back plate 11, the outer edge 12p of the notch recess slides on the upper surface 11s of the extending portion 11a. . At this time, the lower edge 12q at the lower end does not slide with respect to the wall surface W because the side plate 12a is inclined.
[0021]
Then, as shown in FIG. 2C, the height of the shaft core C of the hinge 13 is determined by the sliding position of the outer edge 12p of the notch recess, and the outer edge 12p of the notch recess is located immediately below the shaft core C. It is sometimes highest, that is, it is lifted by the distance between the axis C and the outer edge 12p of the notch recess. The nut 15 is fixed at a height corresponding to the position at that time, and does not hinder the movement of the housing 12.
[0022]
Thereafter, as shown in FIG. 2 (d), when the housing 12 is fully opened, the edge 11d of the back plate 11 retreats to a position where it does not collide with the edge 12d of the side plate 12a, and the clearance dimension is taken. This does not prevent the casing 12 from being fully opened. In order to prevent the edge 11d from colliding with the edge 12d, the distance between the shaft core C and the back plate front edge 11e may be set larger than the distance between the shaft core C and the lower end outer edge 12q.
[0023]
When the housing 12 is closed, the above-described reverse process can be performed to close the housing 12 with no gap between the housing 12 and the wall surface W.
[0024]
In the above embodiment, the horizontal distance between the edge 11d of the back plate 11 and the side plate 12a in the state where the housing 12 is closed, that is, the clearance dimension, is the amount that the edge 12d of the side plate 12a enters when the housing 12 is fully opened. Thus, although the edge 11d of the back plate 11 is formed to recede, it may be configured to have a smaller relief dimension. In this case, the height of the nut 15 is set high so that the rotation trajectory of the back plate front edge 12q does not interfere with the back plate front edge 11e so as to avoid a collision between the side plate 12a and the back plate 11. When opening the housing 12, if the housing 12 is sufficiently lifted and opened, the height of the nut 15 is set sufficiently high, so that the back plate front edge 12q can avoid collision with the back plate front edge 11e. Therefore, the housing 12 can be fully opened.
[0025]
The relief dimension may be selected as zero. Then, the housing end 12b and the edge 11d of the back plate 11 come into contact with each other when the housing 12 is closed. In this case, the height of the nut 15 is set sufficiently high by the same method as described above. When opening the housing 12, if the housing 12 is first lifted sufficiently before being opened, the height of the nut 15 is set sufficiently high, so that the housing 12 can be fully opened.
[0026]
By the way, with such a configuration, even if the fixing means 17 is simply removed, the housing end 12b and the edge 11d cannot be opened due to collision, so that ordinary people do not open it unnecessarily. It has become a structure.
[0027]
When the clearance dimension is small, the required play F1 dimension in the thickness direction of the back plate 11 of the hinge 13 is determined as follows.
[0028]
As shown in FIG. 2C, the position of the nut 15 is such that, in the process of opening the housing 12, the lower end outer edge 12q farthest from the hinge 13 axis C at the housing end 12b and the back plate 11 is compared with the closest back plate front edge 11e at the edge 11d, and the height is determined when the side plate 12a and the hinge 13 are lifted so that the back plate front edge 11e is longer. Thus, after the position of the nut 15 is determined by providing the hinge plate 13b with the play F1 in the thickness direction of the back plate 11, the nut 15 is fixed with a metal adhesive or the like.
[0029]
As described above, in the first embodiment, the back plate attached to the wall surface, the housing that covers the front surface of the back plate, the coupler that connects the back plate and the housing so that the housing can be rotated, In the operation panel composed of the back plate and the fixing means for holding the housing in the closed state, the coupling tool is attached to the inside of the operation panel, and the edge of the back plate in the range enclosed by the housing in the closed state of the housing Since the casing is covered and concealed and play is provided to the connector so that the chassis does not interfere with the back plate and wall surface during the process of opening the chassis, play of the connector is used in the process of opening the chassis. Since the housing can be lifted up, the housing can be opened without the lower end of the housing colliding with the wall surface. Since the collision of the plates can be avoided, the housing can be opened, and the connecting tool is attached inside the operation panel. The entire circumference of the back plate of the edge of the range housing surrounding casing is maintained aesthetics to mask without gaps, a reliable operation panel is obtained since no foreign matter enters.
[0030]
Embodiment 2. FIG.
In the first embodiment, the extending portion 11a is provided on the back plate 11, but in the second embodiment, a simple rectangular back plate having no extending portion 11a is used. In this case, the extending portion 11a, the upper surface 11s, and the outer edge 12p of the notch recess are not present, and the same reference numerals as those in the first embodiment are used for the other reference numerals. Further, the side plate 12a is placed on the wall surface W instead of the upper surface 11s when the housing 12 is fully opened. However, if the side plate 12 a is thinner than the back plate 11, the side plate 12 a is not placed on the wall surface W and floats slightly.
[0031]
When opening the casing 12, the height of the nut 15 is set high so that the rotation trajectory of the back plate front edge 12q does not interfere with the wall surface W so as to avoid a collision between the side plate 12a and the wall surface W. That is, the height position of the nut 15 is determined so that the height when the hinge 13 is lifted highest from the wall surface W can be made larger than the distance between the hinge 13 axis C and the lower edge 12q.
[0032]
Further, the horizontal distance, that is, the clearance dimension between the edge 11d of the back plate 11 and the side plate 12a in the state where the housing 12 is closed is calculated by taking the amount of the edge 12d of the side plate 12a in the fully opened state of the housing 12 into the back plate 11. The edge 11d is formed by retreating. That is, the distance between the axis C of the hinge 13 and the lower end inner edge 12r is longer than the distance between the axis C and the back plate front edge 11e.
[0033]
When the housing 12 is opened, the height of the nut 15 is set high, so that the hinge 13 can escape in the thickness direction of the back plate 11, and the back plate leading edge 12q slides on the wall surface W. Can be opened. Since the edge 11d of the back plate 11 has a clearance dimension with respect to the edge 12d of the side plate 12, the housing 12 can be fully opened.
[0034]
In the rectangular back plate, the clearance dimension of the edge 11d with respect to the edge 12d may be zero. In this case, when the housing 12 is fully opened, the side plate 12a is placed on the upper surface of the back plate 11 instead of the wall surface W, and the other clearance dimensions when the extending portion 11a in the first embodiment is provided. The same as in the case of zero.
[0035]
In the first and second embodiments, the play of the connecting tool is made at the position of the nut 15 by inserting the hinge plate 13b through the screw 14 standing vertically to the back plate 11. The hinge plate 13b on the plate 11 side may be fixed, and the screw hole of the hinge plate 13a on the measurement plate 12a side may be formed into a long hole in the plate thickness direction of the back plate 11 to create play.
[0036]
In the first and second embodiments, a hinge is used as a connector, but a chain or a link mechanism may be used.
[0037]
Embodiment 3 FIG.
FIG. 3 is an explanatory view showing the internal structure of the operation panel in a fully opened state, and is an explanatory view showing a state in which some hinges are removed. FIG. 4 is an enlarged vertical cross-sectional view of the main part showing the opening / closing process of the operation panel at the hinge part, where (a) shows a closed state, (b) shows a half-open state, and (c) shows a fully-open state.
[0038]
The configuration of the second embodiment will be described below with reference to FIGS.
W is a wall surface, 2 is an operation panel attached to the wall surface W, 21 is rectangular, for example, an H-shaped back plate partially extending at the four corner ends, and 21a is a partially extended portion of the back plate 21. Each extension part used as a wall surface attachment part, 21d is an edge of the back plate 21, 21e is a back plate front edge which is a front edge of the edge 21d, and 21s is an upper surface of the extension part 21a.
[0039]
Reference numeral 22 denotes a housing that covers the entire periphery of the edge of the back plate 21 except for the extending portion 21a by cutting out the extended portion 21a portion of the back plate 21 with the thickness of the extending portion 21a. The side plate 22a is a side plate 22a, the side plate 22a is a side wall 22a, and the extension 21a portion of the back plate 21 is left uncut by the thickness of the extension 21a, and 22d is the side of the housing end 22b. As shown in FIG. 4B, which is a longitudinal sectional view of a portion of the back plate 21 that is an edge and does not have the extending portion 21a, the edge 21d of the back plate 21 in the process of opening the housing 22 is the side plate 22a. Is lifted together with the hinge 23 so that the edge 22d is provided at a position where the edge 21d can be displaced. Reference numeral 22p denotes an outer edge of a notch recess in the side plate 22a that abuts the upper surface 21s of the extending portion 21a when the casing 2 is closed. When the casing 2 is closed, the casing 22 and the back plate 21 are fixed by fixing means such as screws (not shown) as will be described later. Are fixed so that there is no gap between the upper surface 21s and the outer edge 22p of the notch recess.
[0040]
Reference numeral 23 denotes a hinge connected to the front surface of the back plate 21 and the inside of the side plate 22a, that is, a hinge attached to the inside of the operation panel 2. For example, a commercially available one is used. 23a is a first hinge plate of the hinge 23 fixed to the side plate 22a side, and 23b is a second hinge plate of the hinge 23 attached to the back plate 21 side.
[0041]
Reference numeral 24 denotes a screw which stands vertically on the back plate 21 and is inserted into a screw hole (not shown) of the second plate 23b of the hinge 23. Reference numeral 25 denotes a nut which is screwed into the screw 24 and is fixedly bonded at a predetermined position. Between the plate 21 and the hinge plate 23b, for example, an elastic body penetrating through the screw 25, for example, a string-wound spring, a sponge having a strong restoring force, or a rubber formed body. Reference numeral 27 denotes an insertion hole for the screw 24 formed in the back plate 21, and C denotes an axis of the hinge 23.
[0042]
As shown in FIG. 4A, L1 is the vertical distance from the axis C in the closed state of the casing 22 to the edge 22d of the side plate 22a, and L2 is from the axis C in the closed state of the casing 22. The horizontal distance to the edge 21d of the back plate 21 is shown. If the distance L2 is equal to or greater than L1, the edge 22d does not collide with the edge 21d when the housing 22 is fully opened.
[0043]
However, if a commercially available product is used for the hinge 23, the distance L2 may be less than L1 due to the thickness of the back plate 21. In this case, a method is adopted in which the side plate 22a is lifted together with the hinge 23, escapes upward, and the collision between the edge 22d and the edge 21d is avoided. When escaping upward, it is necessary to determine the height position of the nut 25 that restricts the hinge 23.
[0044]
As shown in FIG. 4 (b), the predetermined position of the nut 25 is that the distance from the hinge 23 axis C in the opening process of the casing 22 is the farthest lower end outer edge 22q at the casing end 22b. The nut 25 is fixed at a height position when the side plate 22a and the hinge 23 are lifted so that the back plate front edge 21e is longer than the closest back plate front edge 21e at the edge 21d of the back plate 21. . As described above, the play F2 in the plate thickness direction is provided on the hinge plate 23b to determine the position of the nut 25, and then the nut 25 is fixed with a metal adhesive or the like.
[0045]
Next, the operation will be described with reference to FIG.
In the state (a), the casing 22 is fixedly closed so that the back plate 21 is not rattled by the play F2 of the hinge 23 by fixing means (not shown). For example, the operation panel 2 extends to the wall surface W or the like. It is the state attached by 21a. At this time, the edge 21d of the back plate 21 is covered with the casing 22 except for the extending portion 21a, and a gap between the casing W and the wall surface W is also formed by the casing edge 22b near the hinge 23. In this state, the edge 21d is covered and there is no gap between the upper surface 21s of the extending portion 21a and the outer edge 22p of the notch recess. Therefore, in normal times, the aesthetics are maintained and foreign matter such as dust does not enter.
[0046]
Next, the fixing means (not shown) of the operation panel 2 attached to the wall surface W is removed as necessary for maintenance inspection or the like so that the housing 22 can be opened from the back plate 21.
[0047]
As shown in FIG. 4B, in the process of opening the casing 22, when the edge 22d of the casing end 22b is likely to be caught on the edge 21d of the back plate, the elastic body 26 pushes up the hinge plate 23b. Since the height position of the nut 25 is also set sufficiently high, it can be easily dodged.
[0048]
As shown in FIG. 4C, after that, the side plate 22a is overlaid on the upper surface 21s of the extending portion 21a, the housing end 22b is overlaid on the back plate 21, and the housing 22 is opened 90 degrees. Fully open.
[0049]
When the casing 22 is closed, the reverse process described above is performed, the casing 22 is lifted, the edge 22d of the casing end 22b passes the edge 21d of the back plate 21, and the casing 12 is closed. The casing 22 is closed and fixed to the back plate 21 by a fixing means that does not. At this time, when the hinge 22 is lifted due to the elastic body 26, the case 22 is pressed and fixed. In this closed state, the edge 21d of the back plate 21 except the extending portion 21a is covered by the housing 22 so that the entire circumference of the edge 21d of the back plate 21 surrounded by the housing 22 is covered with the housing edge 22b. As a result, the edge 21d is covered with no gap between the wall surface W and there is no gap between the upper surface 21s of the extending portion 21a and the outer edge 22p of the notch recess.
[0050]
With the configuration of the third embodiment as described above, a back plate attached to the wall surface, a box-shaped housing that covers the front surface of the back plate, a hinge that connects the back plate and the housing, a back plate and a housing In the operation panel composed of the fixing means for holding the body in the closed state, the hinge is connected between the front surface of the back plate and the inside of the case, and the back plate in the range enclosed by the case in the closed state of the case The casing covers the entire circumference of the edge, and the hinge plate on the back plate side is provided with play in the thickness direction of the back plate, and an elastic body is placed between the back plate and the hinge plate on the back plate side. Because it is interposed, the entire circumference of the back plate edge and the hinges in the range enclosed by the housing can not be seen from the outside, so the aesthetics are maintained, and foreign matter also enters to cover the entire circumference of the back plate edge enclosed by the housing. A highly reliable operation panel can be obtained. Further, when the casing is lifted to avoid a collision between the casing and the back plate in the process of opening the casing, the casing is pushed up by the elastic body, so that it can be easily opened.
[0051]
In addition, since the casing is pushed up by the elastic body in the process of opening the casing, there is no sliding such as the upper surface 11s of the extending part 11a and the outer edge 12p of the notch recess of the casing 12, and the upper surface 21s and the like. This eliminates problems such as paint peeling on the sliding surface.
[0052]
In addition, although the extending part was provided in the back board in the above Embodiment 3, a simple rectangular back board may be sufficient.
[0053]
【The invention's effect】

The entire periphery of the edge of the backboard that surrounds and the hinges are not visible from the outside, so the appearance is good, and the entire periphery of the edge of the backboard that the enclosure encloses is hidden, so there is no foreign matter and a highly reliable operation panel is obtained. It is done.
Further, in the process of opening the casing, the casing can be floated using the play of the hinges, so that the casing can be opened without the lower end of the casing colliding with the wall surface.
Further, when the casing is fully opened, the edge of the back plate is retracted to a position where it does not collide with the edge of the side plate, and the clearance dimension is taken, so that the casing is not fully opened.
[0054]
In addition, prior between Kiseban before Symbol second hinge plate, it is interposed an elastic body for pushing up the housing in the process of opening the housing. As a result, when the case is lifted to avoid collision between the case and the back plate in the process of opening the case, the case is lifted by the elastic body, so that the operation panel can be easily opened. Is obtained. Since the case is pushed up by the elastic body in the process of opening the case, there is no sliding such as the upper surface of the extension part and the outer edge of the notch in the case, and there is a problem such as paint peeling on the sliding surface such as the upper surface. Disappear.
