Description

【０００１】
【産業上の利用分野】
本発明は新規な電子機器の筺体に関する。詳しくは、複数の構成部品を組み合わせることによって構成される電子機器の筺体において、分解性及び整備性を損なうことなく、外観の見栄えが良くなるようにしたものである。
【０００２】
【従来の技術】
電子機器の筺体、特に、複数の構成部品を結合することによって構成される筺体においては、一般的に、ネジを用いてこれら複数の構成部品を一体に固着することが多い。
【０００３】
そして、これらネジの頭が筺体の外部表面（以下、「体裁面」という。）に現れて見栄えが悪くなってしまう場合には、見栄えを良くするために、このネジの頭を覆い隠して見えなくするということが一般的に行われている。
【０００４】
例えば、体裁面に凹部を形成し、この凹部内にネジ孔を設けてネジ止めを行い、ネジの頭部をこの凹部内に収納するようにしたものがある。そして、凹部に体裁面と面一となるようなカバー体を取り付けてネジが見えないようにしている。
【０００５】
このようなカバー体は、例えば、凹部内に設けられた係合孔にカバー体から突出した係合片が係合し、カバー体が支持固定されるという構造となっている。
【０００６】
【発明が解決しようとする課題】
ところで、修理等のために電子機器の筺体を分解する必要が生じた際には、ネジの頭がカバー体によって隠されているので、まず最初にカバー体を取り外す必要がある。
【０００７】
しかし、カバー体は上述したように、例えば、カバー体の係合片が凹部内の係合孔に係合して支持固定されているという構造であり、しかも、カバー体の表面が体裁面と略面一となっており段差もなく、更に、カバー体は凹部の略全てを覆い隠す形状とされていてほとんど隙間がないので、カバー体を取り外すためにはカバー体と筺体との間に先端の細いもの、例えば、マイナスドライバー等を差し込んで抉ることによって強引に外すしか方法がなかった。
【０００８】
しかし、このような方法では、カバー体が合成樹脂等のように変形や破損しやすい材質で形成されている場合においては、カバー体に局部的に加わる大きな力によって傷が付いたり変形が生じたりして使用できなくなったり、体裁を損なってしまったり、甚だしい場合には破損してしまうという問題があった。
【０００９】
【課題を解決するための手段】
そこで、本発明電子機器の筺体は、少なくとも２つの構成部品をネジにより互いに取着してなり、一方の構成部品は他方の構成部品を前記ネジで固定するためのボスを有し、他方の構成部品は傾斜面部を有する容器状の形状をなし、前記傾斜面部に形成された前記ボスの軸方向の断面が略直角三角形状を成す凹部に前記ネジの挿入部を有する電子機器の筺体において、前記凹部の開口部の略全体を覆って前記傾斜面部と一体化すると共に、前記傾斜面部と一体化する位置と、前記ボスの軸方向に略平行な前記凹部の底部に略当接する位置との間を移動可能となるように取着されたカバー体と、その付勢力により通常は前記カバー体を前記傾斜面部と一体化する位置に保持すると共に、外部から前記カバー体を押圧したときだけ前記カバー体を前記ボスの軸方向に略平行な前記凹部の底部に略当接する位置まで移動させる弾性体とを有し、工具による前記ネジの着脱作業時には外部から前記カバー体を押圧することにより前記カバー体を前記ボスの軸方向に略平行な前記凹部の底部に略当接する位置に移動させると共に、前記着脱作業時以外のときは前記弾性体の付勢力により前記カバー体が前記傾斜面部と一体化する位置に復元するようにしたものである。
【００１０】
【作用】
従って、本発明電子機器の筺体においては、カバー体によって凹部内のネジが隠蔽されるので見栄えが良く、しかも、修理等のためにネジを緩める必要がある時は、カバー体を筺体の内部方向に押圧すると凹部が露出し、このまま押圧を中止すれば所定の位置に復元するという構造であるので、カバー体を取り外すことなくネジを締めたり緩めたりすることができ、作業性が向上する。
【００１１】
【実施例】
以下に本発明電子機器の筺体の詳細について図示した実施例に従って説明する。
【００１２】
図１乃至図４は本発明をディスプレイ装置の筺体に適用した実施例１を示すものである。
【００１３】
ディスプレイ装置１は、後述するように合成樹脂製の筺体内に回路基板や陰極線管（以下、「ＣＲＴ］という。）が収納され、同様に合成樹脂製のスタンドによって筺体が支えられている構造を有している。
【００１４】
２は筺体であり、該筺体２は構成部品３、４及び５がそれぞれ組み合わされて成るものである。そして、この実施例においては、構成部品３は枠体、構成部品４はリアカバー４、そして、構成部品５はボトムカバーである。
【００１５】
尚、以下の説明において、前後左右及び上下の方向について述べる時は、ディスプレイ装置１の通常の使用時における方向、即ち、ＣＲＴの表示面が露出している側を前方、その逆の方向を後方とし、前方からＣＲＴの表示面を見た場合における上下左右を上下左右の方向とする。
【００１６】
枠体３は略額縁状の前面パネル６と、該前面パネル６の外周縁から後方へ向けて突出した周壁７から成り、前面パネル６には図示しないＣＲＴの表示部の前面が外部に臨まされる開口が形成されている。
【００１７】
また、枠体３の周壁７の後端縁は適宜な形状、例えば、段部等が形成され、これがリアカバー４の前端縁と衝合するようになっており、更に、周壁７の内側の壁面からはそれぞれがある程度離間して数カ所に後方へ向かって突出したボス部８、８、・・・（図面においては上部にある１つのみを示す。）が形成されている。
【００１８】
リアカバー４は、前方及び下方に向かって開口し、枠体３の後端と同じ開口径を有する容器状の前半部９と、これに続く略箱状を成す後半部１０とが一体に形成されて成るものである。
【００１９】
上記前半部９は、前端部が枠体３と同じ径を有する半枠状を成すようにされ、この半枠状の部分に続く上部を覆う上面壁１１は後方に行くに従って徐々に下方へ変位するようにされ、後方を覆う背面壁１２は上方から見て略円弧状を成すように湾曲している。
【００２０】
そして、前記したように枠体３とリアカバー４とが結合された時には、周壁７と上部壁１１及び背面壁１２とが段差のない一体的な面となって体裁面１３を形成するようになっている。
【００２１】
また、上面壁１１の体裁面１３には、図１及び図２に示すように、前記枠体３のボス部８、８の位置と対応した位置に、左右に離間して２カ所に上方及び後方に向かって開口した凹部１４、１４が形成されている。
【００２２】
尚、この実施例においては、筺体２の凹部１４が上部の２つのみしか設けられていないものを示したが、他のネジ止めによって枠体３、リアカバー４及びボトムカバー５をそれぞれ固定する箇所にも設けても良い。
【００２３】
上記各凹部１４の水平に延びた底面１５にはそれぞれ、図２及び図３に示すように、後述するカバー体の係合片と係合する係合孔１６、１６、・・・が両側壁に沿って４箇所、前後方向に延びて形成されると共に、該係合孔１６、１６、・・・のうち前側の一対のもの１６、１６よりも更に前方には、後述する弾性体の一部を収納する円形に稍窪んだ弾性体収納凹部１７が形成され、また、該弾性体収納凹部１７の前方の上下に延びた壁面は、この上方の凹部１４の開口縁よりも更に前方に窪むことによってネジ収納凹部１８とされ、該ネジ収納凹部１８には中央にネジ挿通孔１９が貫設されている。
【００２４】
また、リアカバー４の後半部１０は、天板２０と左右の側板２１、２２と背板２３とによって画成された略箱状を成し、それぞれの前端が前半部９の背面壁１２に連結して一体に形成されている。
【００２５】
ボトムカバー５は主にリアカバー４の下方を覆うものであり、リアカバー４を上方より見た形状と略同じ平面形状を成し、前部を除く側方及び後方の周縁部は立壁によって囲まれている。そして、ボトムカバー５の前端縁はリアカバー４と同様に枠体３の後端と係合し、立壁の上縁がリアカバー４の下縁と係合する。
【００２６】
また、ボトムカバー５はスタンド２４の上に載置されて、適宜な手段によって連結され、ディスプレイ装置１を支持するようになっている。
【００２７】
２５、２５は前記凹部１４、１４を覆って隠し、上面壁１１の表面、即ち、体裁面１３と一体化させて見せるための、例えば、合成樹脂製のカバー体である。
【００２８】
各カバー体２５は、凹部１４の開口の平面形状及び大きさと略同じ形状、大きさを有する長方形の板状の主部２６と係合片２７、２７及び２８、２８とから成る。
【００２９】
そして、上記係合片２７、２７及び２８、２８はある程度の弾発性を有するものであり、主部２６の長手方向の中央の位置よりも稍両端部寄りの位置で、且つ、短手方向における両端部に離間した４カ所の位置に、前記係合孔１６、１６・・・の位置と合わせて主部２６の下面から一体に後斜め下方に向かって突出形成されている。
【００３０】
また、該係合片２７、２７及び２８、２８それぞれの下端部の外側を向いた面には係合爪２９、２９及び３０、３０がそれぞれ突出形成されている。
【００３１】
そして、上記係合爪２９、２９及び３０、３０はそれぞれ、図４に示すように、係合片２７、２７（係合爪２９、２９及び３０、３０の形状は全く同じなので、ここでは図４において図示されている係合爪２９、２９について説明する。）の先端部に対応した、係合孔１６、１６、・・・内に挿入し易くするために上方へ行くに従って外方に変位する傾斜面２９ａ、２９ａ（係合爪３０、３０においては３０ａ、３０ａである。以下同じ。）と、次いで、外側面２７ａ、２７ａと略並行に上方に延びる面２９ｂ、２９ｂ（３０ｂ、３０ｂ）と、最後に外側面２７ａ、２７ａと略直角を為す面２９ｃ、２９ｃ（３０ｃ、３０ｃ）とによって形成されており、該略直角を為す面２９ｃ、２９ｃ（３０ｃ、３０ｃ）が係止面となる。
【００３２】
尚、係合片２７、２７及び２８、２８のうち前方の一対である２７、２７は、その長さが後方の一対２８、２８の長さよりも略１．５倍の長さを有するようにされている。これは、カバー体がリアカバー４の凹部１４を覆うように取着された場合において、前述したように、リアカバー４の前半部９の上面壁１１、即ちこの部分の体裁面１３が後方へ行くに従って下方に変位しており、しかも、凹部１４、１４の底面１５が水平となっているため、底面１５の係合孔１６、１６と係合した場合において、主部２６の上面が体裁面１３と面一な面となるように長さが合わすためである。
【００３３】
また、係合片２７、２７及び２８、２８の前後方向における幅は、それぞれ、前記係合孔の１６、１６、・・・の開口の前後方向の長さの約半分とされ、また、厚みは係合爪２９又は３０が形成された下端部で係合孔１６、１６、・・・の左右方向における幅とほぼ同じ厚みを有し、これ以外の部分では係合孔１６、１６、・・・の左右方向における幅の約半分程度とされている。
【００３４】
そして、それぞれ対を成している係合片２７と２７との間及び係合片２８と２８との間の間隔、即ち、それぞれの外側を向いた面である外側面２７ａと２７ａとの間及び２８ａと２８ａとの間の間隔がそれぞれ係合する係合孔１６、１６、・・・の外側の開口縁間の間隔と略同じになるようにされている。
【００３５】
更に、カバー体２５の下面において、係合片２７、２７が突出している位置よりも更に前方には、円形に窪んだ弾性体収納凹部３１が形成されている。
【００３６】
３２は弾性体であり、本実施例においてはコイルスプリングが用いられ、例えば、弾性体収納凹部１５又は３１のどちらか一方に一端部が収納固定される。
【００３７】
３３、３３、・・・はネジであり、筺体２を構成する各構成部品、即ち、枠体３、リアカバー４及びボトムカバー５を組み合わせて固定するためのものである。
【００３８】
このネジを用いた固定方法は、極めて周知である一般的な方法が用いられる。即ち、ネジ挿通孔が形成された一方の側からネジ３３をネジ挿通孔に挿通し、他方の部材の、例えば、ボス部に螺合させて固定する。
【００３９】
以下に枠体３とリアカバー４との固定部分、特に、筐体２の上部の凹部１４、１４が形成された箇所におけるもののうち一方について図３を用いて説明する。
【００４０】
即ち、枠体３の周壁７の後端とリアカバー４の前端とを衝合させ、そして、リアカバー４の凹部１４内のネジ挿通孔１９にネジ３３を挿通し、該ネジ３３を枠体３のボス部８に螺合させる。
【００４１】
尚、この状態においては、筺体２の外側にネジ３３の頭部が外部から見えて甚だ見栄えが悪い。特に、筺体２の上部等においてはこれが著しく目立つ。
【００４２】
従って、リアカバー４の各凹部１４をカバー体２５で覆って体裁面１３と一体に見えるようにする。
【００４３】
即ち、カバー体２５の主部２６の下面の弾性体収納凹部３１と凹部１４の底面１５の弾性体収納凹部１７との間に弾性体（コイルスプリング）３２を挟み込み、カバー体２５の主部２６を弾性体３２を圧縮する方向（下方）に押圧して係合片２７、２７及び２８、２８を底面の係合孔１６、１６、・・・と位置を合わせて、この中に挿入する。
【００４４】
すると、係合爪２９、２９及び３０、３０の傾斜面２９ａ、２９ａ及び３０ａ、３０ａがそれぞれ係合孔１６、１６、・・・の開口縁と当接し、この当接によってガイドされて係合片２７と２７及び２８と２８はそれぞれ左右で対を為すもの同士の互いの間隔が狭くなるような方向、つまり、内側方向に撓みながら係合孔１６、１６、・・・内に入っていく。
【００４５】
即ち、前述したように、係合片２７、２７及び２８、２８の外側面２７ａ、２７ａ及び２８ａ、２８ａは係合孔１６、１６、・・・の外側の開口縁と略面一であるが、係合爪２９、２９および３０、３０は更にその外側に突出しているため、該係合爪２９、２９および３０、３０が係合孔１６、１６、・・・内に挿入される時には、その突出している分だけ係合片２７、２７及び２８、２８が内側方向に撓むのである。
【００４６】
そして、係合片２７、２７及び２８、２８の先端部の係合爪２９、２９及び３０、３０が係合孔１６、１６、・・・を貫通してリアカバー４の内面側に突出した時点で上記押圧を解除すると、圧縮されていた弾性体３２の復元力によって係合片２７、２７及び２８、２８は係合孔１６、１６、・・・から抜け出ようとするが、撓んでいた係合片２７、２７及び２８、２８が元に戻り係合爪２９、２９及び３０、３０が係合孔１６、１６、・・・の開口縁よりも更に外側に突出するために、係合爪２９、２９及び３０、３０の係止面２９ｃ、２９ｃ及び３０ｃ、３０ｃがそれぞれ、係合孔１６、１６、・・・の下側開口縁に引掛かり、これによってカバー体２５はリアカバー４に係止される。
【００４７】
従って、この状態において、カバー体２５の主部２６の上面がリアカバー４の体裁面１３と面一となり、凹部１７及びネジ３３の頭部が隠蔽される。
【００４８】
次に、例えば、修理するためにディスプレイ装置１の筺体２を分解する必要があってネジ３３、３３、・・・を外す場合の方法について説明する。
【００４９】
この時には、カバー体２５の主部２６の上面の前方寄り、即ち、弾性体収納凹部３１が形成された位置の近傍を指などで下方に押圧する。
【００５０】
すると、弾性体３２が圧縮され、図３に二点鎖線で示すように、カバー体２５が全体的に斜め下方に押し下げられて係合片２７、２７及び係合片２８、２８が係合孔１６、１６、・・・内でリアカバー４の内部に更に入っていき、係合爪２９、２９及び３０、３０と係合孔１６、１６、・・・との係合状態が一時的に解除され、主部２６が凹部１４の底面１５と略並行となり、凹部１４のネジ収納凹部１８内のネジ３３の頭部が露出する。
【００５１】
尚、ネジ３３、特にその頭部は前述したように凹部１４の前端の開口縁よりも更に前方に窪んだネジ収納凹部１８内にあるので、上記動作中においてカバー体２５の前端部と干渉することがないようになっている。
【００５２】
しかして、上記状態のままドライバーを使ってネジ３３を緩めたり、あるいは、ネジ挿通孔１９にネジ３３を挿入して締めたりすることができ、作業が終われば、カバー体２５の押圧を解除すれば弾性体３２の復元力によってカバー体２５は元の状態に戻る。
【００５３】
また、カバー体２５の取り外しもドライバー等の工具を使用することなく簡単に行うことができる。
【００５４】
即ち、ネジ３３を緩めたり締めたりする場合と同様に、カバー体２５の主部２６の前部、弾性体収納凹部３１の形成位置の略上方近傍を指などで押圧し続ける。
【００５５】
すると、図３に示すように、カバー体２５の主部２６の後端部２６ａがリアカバー４の凹部１４から後方に突出する。
【００５６】
これは、カバー体２５の主部２６の前後長が凹部１５の底面１５の前後方向の長さよりも長いからである。
【００５７】
そこで、上記後方に突出した部分である後端部２６ａを稍力を入れてこのまま斜め上方に持ち上げれば、係合片２７、２７及び２８、２８は、前述したカバー体２５を取り付ける場合と同様に、係合片２７、２７及び２８、２８のそれぞれの対向したもの同士の間隔が近づくような方向、つまり、内側方向に撓みながら係合孔１６、１６、・・・から抜け出て、カバー体２５を取り外すことが簡単にできる。
【００９１】
【発明の効果】
以上に記載したところから明らかなように、本発明電子機器の筺体は、少なくとも２つの構成部品をネジにより互いに取着してなり、一方の構成部品は他方の構成部品を前記ネジで固定するためのボスを有し、他方の構成部品は傾斜面部を有する容器状の形状をなし、前記傾斜面部に形成された前記ボスの軸方向の断面が略直角三角形状を成す凹部に前記ネジの挿入部を有する電子機器の筺体において、前記凹部の開口部の略全体を覆って前記傾斜面部と一体化すると共に、前記傾斜面部と一体化する位置と、前記ボスの軸方向に略平行な前記凹部の底部に略当接する位置との間を移動可能となるように取着されたカバー体と、その付勢力により通常は前記カバー体を前記傾斜面部と一体化する位置に保持すると共に、外部から前記カバー体を押圧したときだけ前記カバー体を前記ボスの軸方向に略平行な前記凹部の底部に略当接する位置まで移動させる弾性体とを有し、工具による前記ネジの着脱作業時には外部から前記カバー体を押圧することにより前記カバー体を前記ボスの軸方向に略平行な前記凹部の底部に略当接する位置に移動させると共に、前記着脱作業時以外のときは前記弾性体の付勢力により前記カバー体が前記傾斜面部と一体化する位置に復元するようにしたことを特徴とするものである。
【００９２】
従って、本発明電子機器の筺体においては、カバー体によって凹部内のネジが隠蔽されるので見栄えが良く、しかも、修理等のためにネジを緩める必要がある時は、カバー体を筺体の内部方向に押圧すると凹部が露出し、このまま押圧を中止すれば所定の位置に復元するという構造であるので、カバー体を取り外すことなくネジを締めたり緩めたりすることができ、作業性が向上する。
【００９３】
尚、前記実施例において示した各部の具体的な形状乃至構造は、本発明を実施するに当たっての具体化のほんの一例を示したものに過ぎず、これらによって本発明の技術的範囲が限定的に解釈されることがあってはならない。

[Industrial application fields]
The present invention relates to a new electronic device housing. More specifically, the appearance of an electronic device casing constituted by combining a plurality of component parts is improved without degrading disassembly and maintainability.
[0002]
[Prior art]
In a housing of an electronic device, in particular, a housing configured by joining a plurality of components, generally, the plurality of components are often fixed together using screws.
[0003]
If the heads of these screws appear on the outer surface of the housing (hereinafter referred to as “the appearance”) and look bad, the heads of these screws are obscured to improve the appearance. It is common practice to eliminate it.
[0004]
For example, there is a type in which a concave portion is formed in the appearance surface, a screw hole is provided in the concave portion, screwing is performed, and a screw head is accommodated in the concave portion. Then, a cover body that is flush with the appearance surface is attached to the recess so that the screw is not visible.
[0005]
Such a cover body has a structure in which, for example, an engagement piece protruding from the cover body is engaged with an engagement hole provided in the recess, and the cover body is supported and fixed.
[0006]
[Problems to be solved by the invention]
By the way, when it becomes necessary to disassemble the housing of the electronic device for repair or the like, the head of the screw is hidden by the cover body, so it is necessary to first remove the cover body.
[0007]
However, as described above, the cover body has a structure in which, for example, the engagement piece of the cover body is engaged and supported and fixed to the engagement hole in the recess, and the surface of the cover body is the surface of the body. It is almost flush with no step, and the cover body has a shape that covers almost all of the recesses and there is almost no gap, so in order to remove the cover body, the tip is between the cover body and the housing The only way to remove it was to forcefully remove it by inserting a flat-blade screwdriver, etc.
[0008]
However, in such a method, when the cover body is formed of a material that is easily deformed or damaged, such as a synthetic resin, the cover body may be damaged or deformed by a large force locally applied to the cover body. In some cases, it becomes unusable, looks bad, or breaks in severe cases.
[0009]
[Means for Solving the Problems]
Therefore, the housing of the electronic device according to the present invention has at least two components attached to each other with screws, and one component has a boss for fixing the other component with the screws, and the other component. The component has a container-like shape having an inclined surface portion, and the housing of the electronic device having the insertion portion of the screw in a concave portion in which an axial section of the boss formed in the inclined surface portion forms a substantially right triangle shape, Covering substantially the entire opening of the concave portion and being integrated with the inclined surface portion, and between a position where it is integrated with the inclined surface portion and a position where it substantially contacts the bottom of the concave portion substantially parallel to the axial direction of the boss. The cover body attached so as to be movable, and the urging force normally holds the cover body at a position where it is integrated with the inclined surface portion, and the cover body is pressed only when the cover body is pressed from the outside. Body An elastic body that moves to a position that substantially contacts the bottom of the concave portion that is substantially parallel to the axial direction of the boss, and presses the cover body from the outside when the screw is attached or detached by a tool. A position where the cover body is integrated with the inclined surface portion by the urging force of the elastic body when the boss is moved to a position where it substantially contacts the bottom of the concave portion substantially parallel to the axial direction of the boss, and when it is not during the attaching / detaching operation. It is intended to restore to .
[0010]
[Action]
Therefore, in the housing of the electronic device of the present invention, since the screw in the recess is concealed by the cover body, the appearance is good, and when it is necessary to loosen the screw for repair or the like, the cover body is directed in the internal direction When pressed, the recess is exposed, and if the pressing is stopped as it is, the structure is restored to a predetermined position. Therefore, the screw can be tightened or loosened without removing the cover body, and the workability is improved.
[0011]
【Example】
The details of the casing of the electronic device of the present invention will be described below in accordance with the illustrated embodiment.
[0012]
1 to 4 show a first embodiment of the present invention is applied to a housing of the display device.
[0013]
As will be described later, the display device 1 has a structure in which a circuit board and a cathode ray tube (hereinafter referred to as “CRT”) are housed in a synthetic resin casing, and the casing is similarly supported by a synthetic resin stand. Have.
[0014]
Reference numeral 2 denotes a housing, and the housing 2 is formed by combining the components 3, 4 and 5 respectively. In this embodiment, the component 3 is a frame, the component 4 is a rear cover 4, and the component 5 is a bottom cover.

Further, the rear half 10 of the rear cover 4 has a substantially box shape defined by the top plate 20, the left and right side plates 21, 22 and the back plate 23, and each front end is connected to the rear wall 12 of the front half 9. And are integrally formed.
[0025]
The bottom cover 5 mainly covers the lower part of the rear cover 4 and has substantially the same planar shape as the rear cover 4 viewed from above, and the side and rear peripheral parts except for the front part are surrounded by standing walls. Yes. The front end edge of the bottom cover 5 is engaged with the rear end of the frame 3 similarly to the rear cover 4, and the upper edge of the standing wall is engaged with the lower edge of the rear cover 4.
[0026]
The bottom cover 5 is placed on the stand 24 and connected by an appropriate means so as to support the display device 1.
[0027]
25 and 25 are cover bodies made of synthetic resin, for example, which cover the concavities 14 and 14 and hide them so as to be integrated with the surface of the upper surface wall 11, that is, the appearance surface 13.
[0028]
Each cover body 25 includes a rectangular plate-shaped main portion 26 having substantially the same shape and size as the planar shape and size of the opening of the recess 14, and engagement pieces 27, 27 and 28, 28.
[0029]
The engaging pieces 27, 27 and 28, 28 have a certain degree of elasticity, and are closer to both ends of the heel than the center position of the main portion 26 in the longitudinal direction and in the short direction. Are formed so as to protrude rearward and obliquely downward from the lower surface of the main portion 26 together with the positions of the engagement holes 16, 16.
[0030]
Further, engaging claws 29, 29 and 30, 30 are respectively formed on the surfaces of the engaging pieces 27, 27 and 28, 28 facing the outside of the lower ends thereof.
[0031]
The engagement claws 29, 29 and 30, 30 are respectively shown in FIG. 4 as the engagement pieces 27 and 27 (the shapes of the engagement claws 29, 29 and 30, 30 are the same. The engaging claws 29 and 29 shown in FIG. 4 are explained.) The outer claws are displaced outwardly so as to be easily inserted into the engaging holes 16, 16. Inclined surfaces 29a, 29a (30a, 30a in the engaging claws 30, 30; the same applies hereinafter), and then surfaces 29b, 29b (30b, 30b) extending upward substantially parallel to the outer surfaces 27a, 27a. Finally, the surfaces 29c and 29c (30c and 30c) which are substantially perpendicular to the outer surfaces 27a and 27a are formed. The surfaces 29c and 29c (30c and 30c) which are substantially perpendicular to each other serve as locking surfaces. .
[0032]
It should be noted that among the engagement pieces 27, 27 and 28, 28, the front pair 27, 27 has a length approximately 1.5 times longer than the rear pair 28, 28. Has been. This is because, when the cover body is attached so as to cover the concave portion 14 of the rear cover 4, as described above, the upper surface wall 11 of the front half portion 9 of the rear cover 4, that is, the appearance surface 13 of this portion goes backward. Further, since the bottom surface 15 of the recesses 14 and 14 is horizontal, the top surface of the main portion 26 is in contact with the body surface 13 when engaged with the engagement holes 16 and 16 of the bottom surface 15. This is because the lengths are adjusted so as to be flush with each other.
[0033]
In addition, the width in the front-rear direction of the engagement pieces 27, 27 and 28, 28 is about half of the length in the front-rear direction of the openings of the engagement holes 16, 16,. Has the same thickness as the width of the engagement holes 16, 16,... In the left-right direction at the lower end where the engagement claws 29 or 30 are formed, and the engagement holes 16, 16,. .. About half of the width in the left-right direction.
[0034]
And the distance between the engagement pieces 27 and 27 and the engagement pieces 28 and 28 that form a pair, that is, between the outer surfaces 27a and 27a, which are the surfaces facing the outside, respectively. , 28a and 28a are set to be substantially the same as the distance between the opening edges on the outside of the engaging holes 16, 16,.
[0035]
Further, on the lower surface of the cover body 25, an elastic body recess 31 that is recessed in a circular shape is formed in front of the position where the engagement pieces 27, 27 protrude.
[0036]
Reference numeral 32 denotes an elastic body. In this embodiment, a coil spring is used. For example, one end portion is housed and fixed in one of the elastic body housing recesses 15 and 31.
[0037]
Reference numerals 33, 33,... Are screws for fixing the components constituting the housing 2, that is, the frame body 3, the rear cover 4, and the bottom cover 5 in combination.
[0038]
As a fixing method using this screw, a generally well-known general method is used. That is, the screw 33 is inserted into the screw insertion hole from one side where the screw insertion hole is formed, and is fixed by being screwed into, for example, a boss portion of the other member.
[0039]
Hereinafter, one of the fixing portions of the frame 3 and the rear cover 4, in particular, the portion where the recesses 14, 14 on the upper portion of the housing 2 are formed will be described with reference to FIG. 3.
[0040]
That is, the rear end of the peripheral wall 7 of the frame 3 is brought into contact with the front end of the rear cover 4, and the screw 33 is inserted into the screw insertion hole 19 in the recess 14 of the rear cover 4, and the screw 33 is inserted into the frame 3. Screwed onto the boss 8.
[0041]
In this state, the head of the screw 33 can be seen from the outside on the outside of the housing 2 and the appearance of the housing is poor. This is particularly noticeable at the top of the housing 2 and the like.
[0042]
Accordingly, each concave portion 14 of the rear cover 4 is covered with the cover body 25 so that it can be seen integrally with the appearance surface 13.
[0043]
In other words, the elastic body (coil spring) 32 is sandwiched between the elastic body housing recess 31 on the lower surface of the main portion 26 of the cover body 25 and the elastic body housing recess 17 on the bottom surface 15 of the recess 14, and the main portion 26 of the cover body 25. Are pressed in the direction of compressing the elastic body 32 (downward), and the engagement pieces 27, 27 and 28, 28 are aligned with the engagement holes 16, 16,.
[0044]
Then, the inclined surfaces 29a, 29a and 30a, 30a of the engaging claws 29, 29 and 30, 30 come into contact with the opening edges of the engaging holes 16, 16,. The pieces 27 and 27 and the pairs 28 and 28 enter the engagement holes 16, 16,... While being bent inward in a direction in which the distance between the pair of left and right is narrowed, that is, inward. .
[0045]
That is, as described above, the outer surfaces 27a, 27a and 28a, 28a of the engagement pieces 27, 27 and 28, 28 are substantially flush with the outer opening edges of the engagement holes 16, 16,. Since the engaging claws 29, 29 and 30, 30 protrude further outward, when the engaging claws 29, 29 and 30, 30 are inserted into the engaging holes 16, 16,. The engagement pieces 27, 27 and 28, 28 bend inwardly by the protruding amount.
[0046]
Then, when the engaging claws 29, 29, 30, 30, 30 at the tips of the engaging pieces 27, 27, 28, 28 project through the engaging holes 16, 16,... To the inner surface side of the rear cover 4. When the pressing is released, the engaging pieces 27, 27 and 28, 28 try to come out of the engaging holes 16, 16,... By the restoring force of the compressed elastic body 32. The engaging pieces 27, 27 and 28, 28 return to their original positions, and the engaging claws 29, 29 and 30, 30 protrude further outward than the opening edges of the engaging holes 16, 16,. The engaging surfaces 29c, 29c and 30c, 30c of 29, 29 and 30, 30 are respectively hooked on the lower opening edges of the engaging holes 16, 16,..., Whereby the cover body 25 is engaged with the rear cover 4. Stopped.
[0047]
Accordingly, in this state, the upper surface of the main portion 26 of the cover body 25 is flush with the appearance surface 13 of the rear cover 4, and the concave portion 17 and the head of the screw 33 are concealed.
[0048]
Next, for example, a method for removing the screws 33, 33,... When it is necessary to disassemble the casing 2 of the display device 1 for repair will be described.
[0049]
At this time, the front side of the upper surface of the main portion 26 of the cover body 25, that is, the vicinity of the position where the elastic body housing recess 31 is formed is pressed downward with a finger or the like.
[0050]
Then, the elastic body 32 is compressed, and as shown by a two-dot chain line in FIG. 3, the cover body 25 is entirely pushed downward obliquely, and the engagement pieces 27 and 27 and the engagement pieces 28 and 28 are engaged with the engagement holes. 16, 16,... Further enters the rear cover 4, and the engagement state between the engagement claws 29, 29, 30, 30 and the engagement holes 16, 16,. Thus, the main portion 26 is substantially parallel to the bottom surface 15 of the recess 14, and the head of the screw 33 in the screw storage recess 18 of the recess 14 is exposed.
[0051]
Since the screw 33, particularly its head, is in the screw storage recess 18 that is recessed further forward than the opening edge of the front end of the recess 14 as described above, it interferes with the front end of the cover body 25 during the above operation. There is no such thing.
[0052]
Thus, the screw 33 can be loosened using the screwdriver in the above state, or the screw 33 can be inserted into the screw insertion hole 19 and tightened. When the work is completed, the pressure on the cover body 25 is released. For example, the cover body 25 returns to the original state by the restoring force of the elastic body 32.
[0053]
Further, the cover body 25 can be easily removed without using a tool such as a screwdriver.
[0054]
That is, as in the case where the screw 33 is loosened or tightened, the front portion of the main portion 26 of the cover body 25 and the substantially upper vicinity of the formation position of the elastic body recess 31 are continuously pressed with a finger or the like.
[0055]
Then, as shown in FIG. 3, the rear end portion 26 a of the main portion 26 of the cover body 25 protrudes rearward from the concave portion 14 of the rear cover 4.
[0056]
This is because the longitudinal length of the main portion 26 of the cover body 25 is longer than the longitudinal length of the bottom surface 15 of the recess 15.
[0057]
Therefore, if the rear end portion 26a, which is a portion protruding rearward, is lifted obliquely upward while applying repulsive force, the engagement pieces 27, 27 and 28, 28 are the same as in the case of attaching the cover body 25 described above. Further, the cover pieces come out of the engagement holes 16, 16,... While being bent in the direction in which the distance between the opposing pieces of the engagement pieces 27, 27 and 28, 28 approaches, that is, inward. 25 can be easily removed.
[0091]
