【背景技術】
【０００４】
たとえば表示装置、操作盤などの電子機器の表示板を、開口を塞ぐようにボックスに取り付ける取付装置として、表示板の裏面に取り付けられ、かつ屈曲部を有する板バネと、ボックス内に設けられ、かつ板バネの屈曲部が係合する突起部と、板バネの屈曲部または突起部に設けられ、かつ表示板の引き抜き時の摩擦力が挿入時の摩擦力よりも大きくなるように係合する係止部とをそなえたものが知られている（特許文献１参照）。
【０００５】
しかしながら、特許文献１記載の取付装置においては、大きな力を必要とはするものの、誰にでも取り外し具を用いずにボックスの外側から取り外すことができるので、盗難防止対策としては不十分であった。

機器取付壁の開口の周縁部に上記6)記載の開口枠が装着され、機器の外方張り出し部の後面に、上記1)〜5)のうちのいずれかに記載の機器取付具が設けられ、機器の筐体が開口枠内に挿入されるとともに、外方張り出し部が額縁の前面に沿って配置された際に、機器取付具のストッパの引掛部が額縁の係合部に係合し、機器取付具のストッパのバネ体操作部と対応する位置において、額縁を機器取付具のベースとの間に解除具挿入用間隙が形成され、額縁と外方張り出し部との間におけるバネ体操作部と対応する位置に、解除具挿入用間隙に臨むスリットが形成されるようになされている機器取付壁への機器取付構造。
【発明の効果】
【００１７】
上記1)の機器取付具によれば、ベースを、前方から機器取付壁の前面における開口の周囲の部分に配置すると、バネ体の引掛部が機器取付壁における開口の周縁部に設けられた係合部に係合して機器取付具の前方への移動が阻止されるので、機器取付具を機器取付壁に簡単に取り付けることができ、しかも前方からの操作では機器取付具を機器取付壁から取り外すことができなくなる。また、機器取付具の後方への移動は、機器取付壁の前面における開口の周囲の部分に配置されたベースによって阻止される。
【００１８】
また、ベースが機器取付壁の前面における開口の周囲の部分に配置された際に、ベースと機器取付壁との間に解除具挿入用間隙が形成されるので、解除具挿入用間隙を通してベース外方から解除具を挿入するとともに、解除具によりバネ体に設けられたバネ体操作部をベース内方に押圧してバネ体をベース内方に弾性変形させることによって、引掛部の係合部への係合を解除して、機器取付具を機器取付壁から取り外すことができる。したがって、機器取付具を機器に設けておけば、解除具を用いることなく機器を機器取付壁から取り外すことはできないが、機器を機器取付壁から取り外す必要が生じた場合には、解除具を用いることにより簡単に機器取付壁から取り外すことができる。しかも、バネ体操作部が引掛部からずれた位置においてバネ体に設けられているので、解除具によりバネ体操作部を押圧する際に、引掛部の係合部からの係合解除の妨げとはならない。
【００１９】
上記1)の機器取付具によれば、比較的簡単な構成で、後方突出部、バネ体、引掛部およびバネ体操作部を有するストッパを形成することができる。
【００２０】
上記2)の機器取付具を機器に設けた場合、機器を機器取付壁に取り付ける際に、機器が機器取付壁の開口に対して若干位置ずれしていたとしても、ガイド部の働きにより、機器取付壁の開口の周縁部によりバネ体の引掛部を確実にベース内方に押圧してバネ体を弾性変形させることができる。
【００２１】
上記3)の機器取付具によれば、比較的簡単な構成で、後方突出部、バネ体、引掛部およびバネ体操作部を有するストッパを形成することができる。
【００２２】
上記4)の機器取付具を機器に設けた場合、機器を機器取付壁に取り付ける際に、機器が機器取付壁の開口に対して若干位置ずれしていたとしても、ガイド部の働きにより、後方突出部を確実に機器取付壁の開口内に嵌め入れることができる。
【００２３】
上記5)の機器取付具によれば、比較的簡単な構成で、後方突出部、バネ体、引掛部およびバネ体操作部を有するストッパを形成することができる。
【００２４】
上記6)の開口枠によれば、機器取付壁が、たとえば石膏ボードにより形成されている場合であっても、機器取付壁における開口の周縁部に設けられる係合部の位置精度を高めることができるので、この開口枠を装着した機器取付壁に、機器取付具を設けた機器を取り付ける際に、引掛部を確実に係合部に係合させることができる。すなわち、石膏ボードからなる機器取付壁への開口の形成は、カッターなどを用いて行われるので、加工精度が高くなく、係合部の位置がずれるおそれがある。したがって、機器取付具を設けた機器を機器取付壁に取り付ける際に、引掛部が係合部に係合しないおそれがある。
【００２５】
上記7)の機器によれば、上記1)〜5)と同様な効果を奏する。
【００２６】
上記8)の機器取付構造によれば、機器を取り外す際に、解除具を挿入する箇所を視認することができ、解除具により確実にバネ体操作部を押圧することができる。
【発明を実施するための最良の形態】
【００２７】
以下、この発明の実施形態を、図面を参照して説明する。なお、全図面を通じて同一部分および同一物には同一符号を付して重複する説明を省略する。
【００２８】
実施形態１
この実施形態は図１〜図１１に示すものであり、石膏ボードからなる機器取付壁に機器を取り付ける場合を示す。
【００２９】
図１は機器を取り付ける機器取付壁および機器取付壁の開口周縁部に装着される開口枠を示し、図２および図３は機器取付具を備えた機器を示し、図４は機器取付具を備えた機器を機器取付壁に取り付ける過程の状態を示す。図５〜図１０は機器取付具を備えた機器を機器取付壁に取り付けた状態を示す。また、図１１は機器取付具を備えた機器を機器取付壁から取り外す過程の状態を示す。
【００３０】
図１に示すように、機器取付壁(1)は石膏ボードからなり、機器取付用の方形の開口(2)があけられている。機器取付壁(1)の開口(2)の周縁部には開口枠(3)が装着されている。開口枠(3)は、機器取付壁(1)前面における開口(2)の周縁部に配置される額縁(4)と、機器取付壁(1)後面における開口(2)の上下両縁部（開口(2)の周縁部における少なくとも対向する１対の縁部）に配置され、かつボルト(6)およびナット(7)（締結手段）により額縁(4)に固定されて額縁(4)とともに機器取付壁(1)を挟着する上下２つの挟着部材(5)とよりなる。
【００３１】
額縁(4)の上下両横部材(4a)および左右両縦部材(4b)の内側縁部には、それぞれ後方に突出して開口(2)内に嵌る位置決め壁(8)が一体に形成されている。額縁(4)の上下両横部材(4a)に形成された位置決め壁(8)の左右両端部にはそれぞれ左右方向に長い貫通穴(9)があけられ、額縁(4)の上下両横部材(4a)の上下方向内側縁部における貫通穴(9)に臨む部分に、それぞれ上下方向内方に突出しかつ後述する機器取付具の引掛部が係合しうる係合部(11)が設けられており、これにより、機器取付壁(1)の開口(2)の周縁部に、後述する機器取付具の引掛部が係合しうるようになっている。また、額縁(4)前面の外周縁部には前方突出壁(12)が形成されており、前方突出壁(12)の上下両辺部の長さ方向中央部の左右両側部に、それぞれ左右方向に長い切り欠き(13)が形成されている。さらに、額縁(4)の四隅部には、それぞれ機器取付壁(1)の開口(2)内に臨む内方突出部(14)が設けられており、各内方突出部(14)にボルト挿通穴(15)があけられている。
【００３２】
上下両挟着部材(5)の左右両側部には、それぞれ機器取付壁(1)の開口(2)内に臨む内方突出部(16)が設けられており、各内方突出部(16)にボルト挿通穴(17)があけられている。そして、額縁(4)および両挟着部材(5)のボルト挿通穴(15)(17)に前方から通されたボルト(6)の先端部にナット(7)をねじ嵌めることによって、額縁(4)および両挟着部材(5)が、機器取付壁(1)を挟着した状態で機器取付壁(1)に固定されている。
【００３３】
図２に示すように、表示装置、操作盤などの機器(20)は、内部に機器本体を構成する部品が収容され、かつ機器取付壁(1)の開口(2)の周縁部に装着された開口枠(3)の額縁(4)を通して開口(2)内に嵌め込まれる筐体(21)と、筐体(21)の周面前端部に固定状に設けられ、かつ筐体(21)が開口枠(3)内に嵌め込まれた際に機器取付壁(1)の前面に沿う外方張り出し部(22)とを備えている。外方張り出し部(22)の外周縁には後方突出壁(23)が一体に形成されている。
【００３４】
機器(20)の外方張り出し部(22)に機器取付具(25)が設けられている。機器取付具(25)は、１つの枠体(27)からなり、かつ機器取付壁(1)の前面における開口(2)の周囲の部分に配置されて開口(2)を囲繞するベース(26)と、ベース(26)となる枠体(27)の上下両枠部材(27a)の後面に左右方向に間隔をおいて設けられた２つのストッパ(28)とを備えている。枠体(27)の後面は、外方張り出し部(22)の後方突出壁(23)の突出縁とほぼ同一垂直面上にある。
【００３５】
ベース(26)となる枠体(27)の上下両枠部材(27a)および左右両枠部材(27b)のベース(26)内方の縁部に、それぞれ後方に突出しかつ機器(20)の筐体(21)の上下両面および左右両側面に面接触する筐体保持壁(29)が一体に形成されている。また、枠体(27)の上下両枠部材(27a)の左右両端部および左右両枠部材(27b)の上下両端部における筐体保持壁(29)よりもベース(26)外方の部分に、後方に突出し、かつベース(26)が開口枠(3)の額縁(4)の前面、すなわち機器取付壁(1)の前面における開口(2)の周囲の部分に配置された際に、額縁(4)を通して開口(2)内に嵌るとともに、額縁(4)の上下両横部材(4a)および左右両縦部材(4b)の位置決め壁(8)（機器取付壁(1)における開口(2)の上下両縁部および左右両側縁部）に当たって枠体(27)の上下方向および左右方向の位置決めを行う位置決め部(31)が一体に形成されている。位置決め部(31)の後端部に、後方に向かってベース(26)内方に傾斜したガイド部(32)が形成されている。
【００３６】
図３に示すように、ベース(26)となる枠体(27)の上枠部材(27a)に設けられた左側のストッパ(28)は、上枠部材(27a)に固定された垂直状の基板(33)と、基板(33)の下縁に一体に形成され、かつベース(26)が開口枠(3)の額縁(4)前面に配置された際に額縁(4)を通して開口(2)内に挿入される後方突出部(34)と、後方突出部(34)に設けられ、かつベース(26)内方に弾性変形しうる板状のバネ体(35)と、バネ体(35)にベース(26)外方に突出するように設けられ、かつベース(26)が開口枠(3)の額縁(4)前面に配置された際に、額縁(4)の係合部(11)に係合してベース(26)の前方への移動を阻止するとともに、バネ体(35)がベース(26)内方に弾性変形した際に係合部(11)への係合が解除される引掛部(36)と、引掛部(36)から左方にずれた位置においてバネ体(35)に設けられ、かつベース(26)が開口枠(3)の額縁(4)前面に配置された際にベース(26)と機器取付壁(1)との間に位置するバネ体操作部(37)と、ベース(26)が開口枠(3)の額縁(4)前面に配置された際に、開口枠(3)の額縁の前面（機器取付壁(1)の前面における開口(2)の周囲の部分）に当たってベース(26)の後方への移動を阻止するがたつき防止部(38)とを有している。引掛部(36)は、引掛部(36)が係合部(11)に係合した際に、ベース(26)と開口枠(3)の額縁(4)との間に隙間が形成される位置にある。すなわち、引掛部(36)の前側縁部はベース(26)よりも後側にある。
【００３７】
枠体(27)の上枠部材(27a)に設けられた左側のストッパ(28)の後方突出部(34)は、ベース(26)の後面と直角をなすように後方に突出した方形の水平板状である。バネ体(35)は、後方突出部(34)のベース(26)後面と直角をなす左側縁部の前部分に左側方に突出するとともに後方突出部(34)と同一平面内に位置するように一体に形成されている。バネ体(35)の後側縁部に、後方に向かって下方（ベース(26)内方）に傾斜したガイド部(39)が一体に形成されている。引掛部(36)は、バネ体(35)の前側縁部の左端部（先端部）に前方に向かって上方（ベース(26)外方）に斜めに突出するように一体に形成されている。バネ体操作部(37)は、バネ体(35)における引掛部(36)よりも後方突出部(34)寄りの部分（右側の部分）で、かつベース(26)が開口枠(3)の額縁(4)前面に配置された際に額縁(4)の前方突出壁(12)の切り欠き(13)と合致する位置に、前方突出状に一体に形成された水平板状である。バネ体操作部(37)は、ベース(26)となる枠体(27)の上下両枠部材(27a)から筐体保持壁(29)にかけて形成された貫通穴(30)に通されている。がたつき防止部(38)は、左右方向に間隔をおいた１対のスリット(41)を、ストッパ(28)の基板(33)の上端から後方突出部(34)の前後方向中間部にかけて形成し、基板(33)における両スリット(41)間に位置する部分を後方に曲げることにより形成されている。枠体(27)の上枠部材(27a)に設けられた右側のストッパ(28)は、左側のストッパ(28)とは左右逆向きに構成されており、同一部分には同一符号を付す。また、詳細な図示は省略したが、ベース(26)となる枠体(27)の下枠部材(27a)に設けられた２つのストッパ(28)は、上枠部材(27a)に設けられた２つのストッパ(28)と上下逆向きに構成されている。
【００３８】
次に、機器(20)を機器取付壁(1)に取り付ける方法について、図４を参照して説明する。
【００３９】
すなわち、機器(20)の筐体(21)を、前方から開口枠(3)の額縁(4)を通して機器取付壁(1)の開口(2)内に嵌め込む。すると、まずストッパ(28)のバネ体(35)の引掛部(36)が開口枠(3)の額縁(4)における上下両横部材(4a)の上下方向内縁部に当たり（図４(a)参照）、さらに機器(20)を後方に押し込むと、引掛部(36)が額縁(4)の内周縁に押されることによりバネ体(35)が上下方向内方に弾性変形し、引掛部(36)が上下方向内方に移動する（図４(b)参照）。このとき、バネ体操作部(37)も上下方向内方に移動する。そして、引掛部(36)が額縁(4)よりも後方に来ると、バネ体(35)が自身の弾性力により元の状態に復帰し、引掛部(36)の先端部が貫通穴(9)内に嵌って額縁(4)の係合部(11)に係合する。こうして、外方張り出し部(22)および機器取付具(25)のベース(26)が、機器取付壁(1)における開口(2)周縁部に装着された開口枠(3)の額縁(4)の前面に配置された状態で、機器(20)が機器取付壁(1)に取り付けられる（図５および図６参照）。
【００４０】
機器(20)の筐体(21)を開口枠(3)内に嵌め込む際に、ストッパ(28)のバネ体(35)のガイド部(39)の働きによって、額縁(4)の内周縁部により確実にバネ体(35)の引掛部(36)をベース(26)内方に押圧してバネ体(35)を弾性変形させることができる。また、ベース(26)の位置決め部(31)のガイド部(32)の働きによって、機器(20)を機器取付壁(1)に取り付ける際に、機器(20)が機器取付壁(1)の開口枠(3)の額縁(4)に対して若干位置ずれしていたとしても、位置決め部(31)を確実に額縁(4)を通して機器取付壁(1)の開口(2)内に嵌め入れるとともに、額縁(4)の位置決め壁(8)に接触させることができる。
【００４１】
機器(20)が機器取付壁(1)に取り付けられた状態においては、引掛部(36)が額縁(4)の係合部(11)に係合することにより、機器(20)の前方への移動が阻止されている（図７参照）。また、ベース(26)の位置決め部(31)が額縁(4)の位置決め壁(8)のベース(26)内方を向いた面に面接触することによって、機器(20)の上下方向および左右方向への移動が阻止されている（図８参照）。また、ストッパ(28)のがたつき防止部(38)の上下方向外端部が額縁(4)の前面に当たることによって、機器(20)の後方への移動が阻止されている（図９参照）。また、バネ体(35)の引掛部(36)が額縁(4)の係合部(11)に係合して、ストッパ(28)のがたつき防止部(38)の上下方向外端部が額縁(4)の前面に当たることによって、機器取付具(25)のベース(26)と開口枠(3)の額縁(4)との間に解除具挿入用間隙(42)が形成されている（図７参照）。そして、額縁(4)の前方突出部(12)の切り欠き(13)により機器(20)の外方張り出し部(22)の後方突出壁(23)と開口枠(3)の額縁(4)の間に、解除具挿入用間隙(42)に臨むスリット(43)が形成されている（図７参照）。さらに、バネ体操作部(37)がスリット(43)と対応する部分に位置している（図１０参照）。なお、機器(20)の外方張り出し部(22)の後方突出壁(23)、および額縁(4)の前方突出部(12)にそれぞれ切り欠きを形成し、両切り欠きによりスリットを形成してもよい。

また、機器(20)が機器取付壁(1)に取り付けられた状態においては、機器取付具(25)は前方から見えることはないので、見栄えが良くなる。しかも、機器取付壁(1)の後側には機器(20)を取り付けるための余計なスペースを必要としない。
【００４３】
次に、機器(20)を機器取付壁(1)から取り外す方法について、図１１を参照して説明する。
【００４４】
まず、薄板状の解除具(44)を、下方から下側のスリット(43)に通して解除具挿入用間隙(42)内に挿入し、ストッパ(28)のバネ体操作部(37)を上方に押し上げる。すると、バネ体(35)が上方に弾性変形し、下側のストッパ(28)の引掛部(36)の係合部(11)への係合が解除される（図１１(a)参照）。このとき、バネ体操作部(37)が、枠体(27)の下枠部材(27a)の筐体保持壁(29)に当たるので、機器(20)は解除具(44)により下側から支持された状態となる。ついで、解除具(44)により機器(20)を支持したままで、解除具(44)を前方に移動させて機器(20)の下端部を開口枠(3)の額縁(4)よりも前方に移動させるとともに、若干下方へ移動させる。すると、上側のストッパ(28)の引掛部(36)が上側の係合部(11)から外れる。その後、機器(20)全体を前方に移動させる。こうして、機器(20)が機器取付壁(1)から取り外される。
【００４５】
実施形態１においては、機器取付具(25)のベース(26)となる枠体(27)の上下両枠部材に、それぞれ少なくとも１つ、ここでは２つのストッパ(28)が設けられている。これに代えて、左右両枠部材に、それぞれ少なくとも１つ、好ましくは２つのストッパが設けられていてもよい。
