【発明の属する技術分野】
本発明は水平な載置面上に縦置き状態や背面を下向きにした横臥状態で定置したり、或いは壁面に壁掛けすることができるタイプの電子機器における支持機構に関し、特に電子機器を定置した状態の外観が悪化したり、壁から脱落し易くなる等の不具合を一挙に解決して商品価値を高めることができる電子機器の支持機構に関するものである。
【０００２】
【従来の技術】
薄型電子機器のように底面が前背面よりも狭い筐体構造であるために自立しにくい電子機器において、これを水平な載置面上に立設する際にはスタンドを用いて機器底面を支持する等して設置安定性を確保する必要がある。また、壁掛け式の電子機器にあっては、壁面に予め固定した壁掛け用金具に対して機器の筐体背面を着脱自在に係止するように構成されている。
このような電子機器としては、例えば無線ＬＡＮ用送受信機、薄型ディスプレイ、空気清浄機、各種リモコン装置等々を挙げることができる。
図７は第１の従来例に係る薄型電子機器の支持機構の説明図である。この薄型電子機器は例えば無線ＬＡＮ用送受信機と称される電子機器であり、パソコン間の通信を無線により行う無線ＬＡＮシステムにおいて使用される送受信機である。この無線ＬＡＮ用送受信機は、通常オフィス等の室内に設置されるため、オフィスのレイアウト等の諸条件に応じて任意の場所に任意の設置方法により設置できるように（ａ）のように背面を下向きにして横置きしたり、或いは（ｂ）の如き樹脂製スタンド（支持具）を使用して（ｃ）のように縦置きしたり、或いは後述するように壁掛け式にする等、種々の設置方法を選択できるように構成される。即ち、薄型電子機器１は、例えばその筐体２の正面３や側面４等に表示部や操作部７を備えており、底面５の面積は、正面３や背面６よりも狭いのが一般である。このため、底面５を下向きにして載置面１０上に立設しようとした場合には自立性が低いために安定度が低下する。このため、（ｂ）に示した如きスタンド８を複数用い、各スタンド８の凹所８ａ内に筐体２の底面５を嵌合させることによって安定した立設状態を確保するようにしている。
しかし、この従来例に係る支持機構にあっては、機器１の直立を安定させるためにスタンド８の凹所８ａ内に筐体下部を差し込むため、スタンドの端部に位置する厚肉部８ｂの一方が筐体正面３の下部とオーラーラップして隠蔽するため、筐体正面のデザイン、外観が損なわれていた。また、表示部や操作部７のレイアウトもスタンドの厚肉部８ｂを回避して設ける必要があるため、機器設計上の制約となっていた。
【０００３】
図８（ａ）（ｂ）及び（ｃ）は、上記従来例における不具合を解決した他の従来例に係る支持機構を示す図であり、（ａ）に示した薄型電子機器１は、前記従来例の電子機器と同様の筐体構造を備えているが、底面５に２つの螺子穴１１を備えた構成が異なっている。この電子機器１は、（ｂ）に示した平板状のスタンド１２に設けた穴１２ａを介して螺子１３を螺子穴１１内に螺着することによって、スタンド１２を筐体底面５に固定した上で、（ｃ）に示したように載置面１０上に縦置きに立設する。
しかし、図８の支持機構にあっては、スタンド１２が平板状であるため、スタンドの一部が筐体正面に干渉してこれを隠蔽するといった不具合は一切発生しないが、スタンドを筐体底面に固定する手段として螺子１３を用いているため、着脱に手間がかかる点と、螺子の分だけコストアップするという問題がある。また、（ａ）のように筐体を横臥させたときに、螺子穴１１が現れるためデザイン的に好ましくないという問題もある。
次に、図９（ａ）（ｂ）及び（ｃ）は、他の従来例に係る薄型電子機器の支持機構の説明図であり、（ａ）に示すようにこの電子機器１の筐体は、底面５に凸形状の穴から成るレール１５が形成されている構成が上記従来例の電子機器の筐体と異なっている。
（ｂ）に示したプラスチック製のスタンド１６は、ベース１７上に逆Ｌ字状の係止片１８を２個対称形状となるように突設した構成を備えており、一対の係止片１８をレール１５の大径部１５ａに差し入れてから両係止片１８を内側へ挟圧して弾性変形させた上で小径部１５ｂ内にスライドして係合させることにより、（ｃ）に示したように筐体底面に固定する。
しかし、この従来例にあっては、筐体底面５に形成した穴であるレール１５が外観に現れ視認されるため、外観デザイン上好ましくない。
【０００４】
次に、図１０（ａ）は、薄型電子機器を壁掛け方式に支持する支持機構の従来構成図であり、この電子機器２１は、その筐体２２の背面２３に複数の係止穴２４を有している。一方、壁３０の垂直面に対しては、壁掛け用金具（支持具）３１が螺子３２によって固定される。壁掛け用金具３１は、螺子穴３３ａを有した平板状のベース３３と、ベース３３の左右両端縁から夫々前方へ突出した係止片３４と、を有する。各係止片３４は、先端が上向きのＬ字状をなしている。（ｂ）はこの電子機器２１を壁掛け用金具３１に係止する手順及び係止した状態を示す断面図であり、図示するように各係止片３４を筐体背面の係止穴２４内に差し込んでから筐体を下方へ下げることによって各係止穴２４の上縁を各係止片３４に着座させて係止するようにしている。
次に、図１１は、図１０に示した従来の電子機器の支持機構の変形例であり、筐体２２の係止穴２４の構造と、係止片３４の形状が異なっているが、係止穴２４内に係止片３４を嵌合させてから筐体２２を少しく下げて係止させることによって、壁掛け用金具３１により筐体２２を係止する点では同じである。
しかし、図１０及び図１１にそれぞれ記載した支持機構はいずれも係止片３４に対して係止穴２４を嵌合させてから筐体を下降させることにより係止穴の上部に係止片を引っ掛けて係止させているに過ぎないため、電子機器を上向きに押し上げる力が作用したときに容易に係止片３４から電子機器が離脱して落下するという不具合がある。
次に、図１２は、他の従来例に係る電子機器の支持機構の説明図であり、（ａ）に示すように薄型電子機器４１は、筐体４２の背面に螺子穴４３を有する。壁掛け用金具４５は、螺子穴４７を有した平板状のベース４６と、ベース４６の両端縁から後方へ伸びたＬ字状の側片４８と、各側片４８に形成した螺子穴４９とを有する。
壁掛け金具４５を用いて電子機器４１を壁５２に固定する際には、螺子５０を用いて予め電子機器４１を金具４５に螺着しておき、その後金具４５を螺子５１を用いて壁５２に固定する。この支持機構は、取り付け作業において電子機器に壁掛け用金具を螺子固定する作業が必要となるため、取り付け作業性が低下するとともに、螺子を用いる分だけコストが増大する。また、側片４８が電子機器の側縁を越えて突出するため、外観が低下する。
【０００５】
【発明が解決しようとする課題】
本発明は上記に鑑みてなされたものであり、水平な載置面上に縦置き状態や背面を下向きにした横臥状態で定置したり、或いは壁面に壁掛けすることができるタイプの電子機器における支持機構において、電子機器を定置、壁掛けした状態での外観が悪化したり、或いは壁から脱落し易くなる等の不具合を一挙に解決して商品価値を高めることができる電子機器の支持機構に関するものである。

【課題を解決するための手段】
上記の課題を解決するため、請求項１の本発明は、背面に被支持部を備えた電子機器の筐体を、略垂直な壁面に固定した支持具によって着脱自在に支持する支持機構において、前記筐体の被支持部は、筐体の背面に横並びに形成した少なくとも２つの第１の嵌合凹所と、該第１の嵌合凹所の下方に形成した第２の嵌合凹所と、を備え、前記支持具は、前記壁面に固定されるベースと、該ベースから前方へ突設された少なくとも２つの第１の係止突部と、該第１の係止突部より下方のベース部から前方へ突設された第２の係止突部と、を備え、前記筐体の各第１の嵌合凹所内に夫々前記支持具の各第１の係止突部を嵌合してから、各第１の嵌合凹所を中心として筐体下部を後方へ回動させることによって第２の係止突部を第２の嵌合凹所内に嵌合させるように構成され、前記支持具を構成する各第１の係止突部は、前記ベースから前方へ突出する基片と、該基片から上方に突出する遊端片と、を備え、前記筐体の被支持部を構成する第１の嵌合凹所は、その内部天井面に係止穴を有し、前記第１の係止突部の遊端片が一旦前記第１の嵌合凹所内に入るように当該筐体を後方へ移動させてから前記係止穴内に入り込むように下降させて係合させることにより前記各第１の嵌合凹所内に夫々前記各第１の係止突部を嵌合してから、前記各遊端片を中心として筐体下部を後方へ回動させることによって第２の係止突部を第２の嵌合凹所内に嵌合させる構成を備え、前記第２の係止突部が前記第２の嵌合凹所内において上下動可能な寸法ａよりも、第１の嵌合凹所の前記係止穴内から前記遊端片を離脱させるために必要な移動距離ｂを大きく設定したことを特徴とする。

【０００７】
【発明の実施の形態】
以下、本発明を図面に示した実施の形態により詳細に説明する。
図１（ａ）乃至（ｄ）は参考例に係る薄型電子機器の支持機構の説明図であり、この支持機構は、薄型電子機器６１の箱型筐体６２の背面６２ｂに装備した嵌合凹所６３と、別部材である支持具７０と、から構成されている。
この電子機器６１は、たとえば無線ＬＡＮ用送受信機であり、筐体６２が薄型であるために底面６２ｃを下向きにして載置面８０上に立設したときに自立性に欠ける不具合があるために、支持具７０によって設置安定性を高めるようにしている。この電子機器の筐体６２は、前面６２ａや側面６２ｄに操作部及び表示部６５を備え、（ａ）に示したごとく背面６２ｂを下向きにした横置き（横臥）状態や、（ｃ）に示したごとき立設(縦置き)状態にして設置し、使用することができる。嵌合凹所６３は、(ｄ)等に示すように筐体背面６２ｂの下部を横長のスリット状にへこませたものであり、後述する支持具７０の支持片７２を整合状態で嵌合させて挟圧保持するように構成する。(ｄ)に示すように筐体内には、プリント基板６６が配置され、プリント基板６６には操作部及び表示部６５を構成する部品等が搭載されている。
支持具７０は、たとえば板金からなり、載置面８０上に定置される底板７１と、該底板７１の適所(後部)から上方へ突設した支持片７２とを備える。
支持具７０の支持片７２の一部(先端)を、筐体側の嵌合凹所６３内に嵌合させた状態で筐体底面６２ｃを底板７１の上面に接触させることにより電子機器６１を安定して立設支持することができる。支持片７２は、底板７１から上方へ立ち上がった第１の屈曲片７２ａと、該第１の屈曲片７２ａから前方へ突出した第２の屈曲片７２ｂとを備え、該第２の屈曲片７２ｂを筐体６２の嵌合凹所６３内に嵌合するように構成されている。
この支持機構の特徴的な構成の一つは、支持片７２の一部、特に底板７１が筐体前面６２ａを隠蔽しない点にある。従って、電子機器の外観デザインを悪化させたり、或いは操作部、表示部６５のレイアウトの妨げとなることがない。
【０００８】
以上の構成を備えた支持機構を備えた電子機器において電子機器単体を(ａ)のように横臥させたとしても、嵌合凹所６３は背面６２ｄに位置するため、外観上問題となることがない。また、この電子機器６１を底面６２ｃを下向きにして載置面８０上に立設する場合には、支持具７０の第２の屈曲片７２ｂを嵌合凹所６３内に嵌合させて組み付けることによって(ｃ)(ｄ)に示したごとき状態にし、この状態で底板７１を載置面８０上に定置すればよい。支持具７０を筐体から離脱させる場合には、第２の屈曲片７２ｂを嵌合凹所６３から抜き取ればよい。
従って、この参考例に係る支持機構によれば、螺子等の格別の固定手段を用いずに支持具を着脱できるので、作業性が良好であるばかりでなく、コスト的にも有利となる。
なお、上記支持機構の構成は一例であり、これに限定されるわけではない。即ち、例えば図２（ａ）は本発明の他の実施形態に係る支持機構を構成する嵌合凹所の背面図、（ｂ）は内部正面図、（ｃ）は内部斜視図、（ｄ）はＡ―Ａ断面図である。
この実施形態に係る支持機構の特徴的な構成は、前記嵌合凹所６３内に、前記支持片７２の第２の屈曲片７２ｂを挟圧保持する挟圧機構９０を設けた点にある。なお、この例では、挟圧機構９０を隣接して左右２つ設け、更に図３（ａ）（ｂ）（ｃ）に示すように各挟圧機構９０に対応して第２の屈曲片７２ｂを二股に分岐した構成としたがこれに限るわけではない。
前記挟圧機構９０は、筐体６２の背面６２ｂの一部を筐体内部へ屈曲させて上下方向へ弾性変形可能に構成した舌片９１を備え、舌片９１の上面にはクリック感を発生させるための小突起９２を突設している。小突起９２を備えた舌片９１は、弾性クリック片を構成している。舌片９１の上方には、筐体内部に延びる天井片９３が所定のギャップを隔てて設けられており、舌片９１と天井片９３との間のギャップが第２の屈曲片７２ｂを差し込む空所９４となっている。
この実施形態の支持機構によれば、支持片７２を嵌合凹所６２の空所９４内に着脱する際に小突起９２が第２の屈曲片７２ｂとの間でクリック感を発生するので、装着時に確実な装着を知ることができる。
【０００９】
次に、図４は本発明に係る薄型電子機器を垂直な壁面に対して着脱自在に取り付ける壁掛け式の支持機構の構成例を示す分解斜視図である。この支持機構は、電子機器６１の筐体６２の背面６２ｂに設けた被支持部を、壁面１００に固定した支持具１０１によって着脱自在に支持するように構成したものである。
筐体６２の被支持部は、筐体の背面６２ｂに横並びに形成した少なくとも２つの第１の嵌合凹所１０２と、該第１の嵌合凹所の下方に形成した第２の嵌合凹所１０３と、を備える。
支持具１２０は、例えば板金から成り、前記壁面１００に固定される平板状のベース１２１と、該ベース１２１の適所、例えば上端縁から前方へ突設された少なくとも２つの第１の係止突部１２２と、該第１の係止突部１２２より下方のベース部（例えば、下端縁）から前方へ突設された第２の係止突部１２３と、を備えている。更に、ベース１２１の両側端縁にＬ字状に屈曲して張り出したブラケット１２４が設けられ、各ブラケット１２４に設けた穴１２５を介して螺子１２６を壁面１００に螺着することにより、ベース１２１を壁面に予め固定する。
各第１の係止突部１２２は、筐体側の各第１の嵌合凹所１０２と一対一の対応関係にあり、嵌合可能となっている。第１の係止突部１２２は、ベース１２１から前方へ突出する基片１２２ａと、該基片１２２ａから上方に突出する遊端片１２２ｂとを備える。また、第２の係止突部１２３は、水平に突出した板状であり、筐体側の第２の嵌合凹所１０３と対応関係にあって嵌合可能となっている。
【００１０】
この実施形態に係る支持機構の特徴は、筐体の各第１の嵌合凹所１０２内に夫々支持具の各第１の係止突部１２２を嵌合してから、各第１の嵌合凹所１０２（遊端片１２２ｂ）を中心として筐体下部を後方（壁面側）へ回動させることによって第２の係止突部１２３を第２の嵌合凹所１０３内に嵌合させるようにした構成にある。このように構成することによって、壁掛け状態にある電子機器に上向きの力を加えても容易に脱落することが無くなる。
第１の嵌合凹所１０２は、図５にも示すようにその内部天井面に係止穴１０２ａを有し、係止穴１０２ａ内に上向きに突出した遊端片１２２ｂを係合させることにより、係止穴１０２ａを中心として電子機器を後方へ回動させることが可能となる。
また、第２の嵌合凹所１０３は、図５に示すように第２の係止突部１２３を挟圧状態に圧接保持できる凹所であってもよいし、或いは図２に示した如き挟圧機構（舌片９１や弾性クリック片）を備えた構造としてもよい。
このように第２の嵌合凹所１０３を備えた電子機器は、支持具１２０を用いて壁掛けすることができるのみならず、図１などに示した立設用の支持具７０を用いて立設させることが可能となる。
【００１１】
以上の構成を備えた支持機構において、電子機器６１を支持具１２０に係止する手順は図５に示す通りである。即ち、まず（ａ）のように電子機器の上部を壁面に接近させるように傾斜させて、壁面１００に固定された支持具１２０の第１の係止突部１２２を筐体側の第１の嵌合凹所１０２内に嵌合させる。このとき、第２の係止突部１２３は、第２の嵌合凹所１０３とは嵌合できない位置関係にある。
続いて、（ｂ）に示すように遊端片１１２ｂが係止穴１０２ａ内に入り込むように電子機器を下降させる。この状態では、第２の係止突部１２３は、第２の嵌合凹所１０３と嵌合可能な位置関係となっている。
続いて、（ｃ）に示すように、遊端片１１２ｂを中心として電子機器６１の下部を後方（壁面方向）へ回動させることにより、第２の係止突部１２３を第２の嵌合凹所１０３内に嵌合、嵌着させる。
この際、第２の係止突部１２３と嵌合凹所１０３との間の上下方向のガタ寸法をａとし、第１の係止突部１２２と第１の嵌合凹所１０２との間の上下方向のガタ寸法をｂとした場合に、ａ＜ｂとなるので、電子機器が上方へ押圧されたとしても第１の係止突部１２２と第１の嵌合凹所１０２との係合がはずれることはない。
これを換言すれば、図５（ｃ）の嵌合、嵌着状態において、第２の係止突部１２３が第２の嵌合凹所１０３内において上下動可能な寸法ａよりも、第１の嵌合凹所１０２（係止穴１０２ａ）内から遊端片１２２ｂを離脱させるために必要な移動距離ｂの方が大きいので、寸法ａの範囲内で電子機器６１が上方へ最大限移動したとしても遊端片１２２ｂは第１の嵌合凹所１０２（係止穴１０２ａ）内に係止し続ける。
なお、支持具１２０のベースの両側端から横方向に張り出したブラケット１２４が、係止された電子機器６１の側方から突出して正面或いは斜め正面方向から視認可能となる場合には、外観が悪化する可能性があるので、ブラケット１２４が支持した電子機器の背面に隠蔽されるように支持具１２０全体の幅方向寸法を短くしてもよい。しかし、この場合には第１の係止突部１２２間の間隔が短くなって電子機器を支持する安定性が低下する虞もある。そこで、例えば、図６（ａ）及び（ｂ）に示すようにベース１２１の裏面に向けて突出した切り起し部１３０を設け、切り起し部１３０に設けた螺子穴１３１を利用して壁面１００に支持具を固定するように構成すれば、ベース面積を減縮することなく、視認不可能な位置に切り起し部１３０を設けて壁面に固定することが可能となる。
なお、本発明の支持機構によって支持可能な対象物としては、無線ＬＡＮ用送受信機の他に、例えば薄型ディスプレイ、空気清浄機、各種リモコン装置等々を例示することができる。
【００１２】
【発明の効果】
以上のように本発明によれば、壁面に壁掛けすることができるタイプの電子機器に用いる支持機構において、電子機器を壁掛けした状態での外観が悪化したり、電子機器が上向きに付勢された際に壁面から脱落し易くなったり、或いは螺子等の格別の固定手段を用いることによる着脱操作性の低下やコストアップ等の不具合を一挙に解決して商品価値を高めることができる。
即ち、本発明は、背面に被支持部を備えた電子機器の筐体を、略垂直な壁面に固定した支持具によって着脱自在に支持する支持機構において、筐体の背面に設けた第１の嵌合凹所内に夫々支持具の第１の係止突部を嵌合してから、第１の嵌合凹所を中心として筐体下部を後方へ回動させることによって第２の係止突部を第２の嵌合凹所内に嵌合させるように構成されているので、支持具によって係止された電子機器に対して上向きの力が加わったとしても脱落する虞がない。また、螺子等の固定具を使用しないので、電子機器の着脱操作性が低下することが無く、またコストアップを回避できる。
本発明によれば、前記嵌合凹所又は第２の嵌合凹所内に、前記支持片又は前記第２の係止突部を挟圧保持する挟圧機構を設けたので、十分な保持力により電子機器を支持具に固定することができる。
本発明によれば、前記嵌合凹所又は第２の嵌合凹所内に、前記支持片又は前記第２の係止突部を着脱した時にクリック感を発生させる弾性クリック片を設けたので、電子機器を支持具に装着する際に装着完了したことを容易に知ることができ、装着不良に起因した電子機器の脱落を防止できる。

BACKGROUND OF THE INVENTION
The present invention relates to a support mechanism in a type of electronic device that can be placed on a horizontal placement surface in a vertically placed state or a recumbent state with the back face down, or can be wall-mounted on a wall surface, and in particular, a state in which the electronic device is placed. The present invention relates to a support mechanism for an electronic device that can increase the value of a product by solving problems such as deterioration of the appearance of the product and facilitating removal from the wall.
[0002]
[Prior art]
In the case of an electronic device that is difficult to stand on its own due to its housing structure that is narrower than the front and rear surfaces, such as thin electronic devices, the stand is used to support the bottom of the device when standing on a horizontal mounting surface. It is necessary to ensure installation stability by doing so. In addition, the wall-mounted electronic device is configured such that the rear surface of the housing of the device is detachably locked to a wall-mounting fixture fixed to the wall surface in advance.
Examples of such electronic devices include wireless LAN transceivers, thin displays, air purifiers, various remote control devices, and the like.
FIG. 7 is an explanatory diagram of a support mechanism for a thin electronic device according to a first conventional example. This thin electronic device is, for example, an electronic device called a wireless LAN transceiver, and is a transceiver used in a wireless LAN system that performs communication between personal computers wirelessly. Since this wireless LAN transceiver is usually installed in a room such as an office, the back side is mounted as shown in (a) so that it can be installed in any place according to various conditions such as office layout. Various installations, such as facing down, or using a resin stand (support) as shown in (b), as shown in (c), or hanging as described later Configured to allow selection of methods. That is, the thin electronic device 1 includes a display unit and an operation unit 7 on the front surface 3 and the side surface 4 of the housing 2, for example, and the area of the bottom surface 5 is generally smaller than that of the front surface 3 and the back surface 6. is there. For this reason, when it is going to stand on the mounting surface 10 with the bottom surface 5 facing downward, the stability is lowered due to low self-supporting property. For this reason, a plurality of stands 8 as shown in (b) are used, and a stable standing state is secured by fitting the bottom surface 5 of the housing 2 into the recess 8 a of each stand 8.
However, in the support mechanism according to this conventional example, the lower portion of the casing is inserted into the recess 8a of the stand 8 in order to stabilize the upright of the device 1, so that the thick portion 8b positioned at the end of the stand Since one side is aurora-wrapped and concealed with the lower part of the housing front 3, the design and appearance of the housing front are impaired. In addition, the layout of the display unit and the operation unit 7 must be provided so as to avoid the thick portion 8b of the stand.
[0003]
FIGS. 8A, 8B, and 8C are views showing a support mechanism according to another conventional example that solves the problems in the conventional example. The thin electronic device 1 shown in FIG. The same housing structure as that of the electronic apparatus of the example is provided, but the configuration in which two screw holes 11 are provided on the bottom surface 5 is different. The electronic device 1 is configured such that the stand 12 is fixed to the housing bottom surface 5 by screwing a screw 13 into the screw hole 11 through a hole 12a provided in the flat plate-like stand 12 shown in FIG. Then, as shown in (c), it is erected vertically on the placement surface 10.
However, in the support mechanism of FIG. 8, since the stand 12 has a flat plate shape, there is no problem that a part of the stand interferes with the front of the casing and hides it. Since the screw 13 is used as a means for fixing the screw, there is a problem that it takes time to attach and detach, and there is a problem that the cost is increased by the screw. Further, when the casing is laid down as shown in (a), the screw hole 11 appears, which is not preferable in terms of design.
Next, FIGS. 9A, 9 </ b> B, and 9 </ b> C are explanatory views of a support mechanism of a thin electronic device according to another conventional example. As shown in FIG. The structure in which a rail 15 made of a convex hole is formed on the bottom surface 5 is different from the case of the above-described conventional electronic device.
The plastic stand 16 shown in FIG. 5B has a configuration in which two inverted L-shaped locking pieces 18 are provided on the base 17 so as to be symmetrical, and a pair of locking pieces 18 is provided. Is inserted into the large-diameter portion 15a of the rail 15 and then both the locking pieces 18 are squeezed inward to be elastically deformed, and then slid into the small-diameter portion 15b to engage with each other, as shown in FIG. Secure to the bottom of the housing.
However, in this conventional example, the rail 15 that is a hole formed in the bottom surface 5 of the housing appears and is visually recognized, which is not preferable in terms of external design.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIGS. 1A to 1D are explanatory views of a support mechanism of a thin electronic device according to a reference example . This support mechanism is a fitting recess provided on a back surface 62b of a box-shaped housing 62 of the thin electronic device 61. FIG. And a support member 70 which is a separate member.
The electronic device 61 is, for example, a wireless LAN transmitter / receiver. Since the casing 62 is thin, the electronic device 61 has a problem that it lacks independence when standing on the mounting surface 80 with the bottom surface 62c facing downward. Further, the installation stability is improved by the support tool 70. The casing 62 of the electronic device includes an operation unit and a display unit 65 on the front surface 62a and the side surface 62d, and as shown in FIG. It can be installed and used in a standing (vertical) state. The fitting recess 63 is formed by denting the lower part of the housing rear surface 62b into a horizontally long slit shape as shown in FIG. And configured to hold the pinching pressure. As shown in FIG. 4D, a printed circuit board 66 is arranged in the housing, and components and the like constituting the operation unit and the display unit 65 are mounted on the printed circuit board 66.
The support tool 70 is made of, for example, a sheet metal, and includes a bottom plate 71 placed on the placement surface 80 and a support piece 72 protruding upward from a proper position (rear part) of the bottom plate 71.
The electronic device 61 is stabilized by bringing the housing bottom surface 62c into contact with the top surface of the bottom plate 71 in a state where a part (tip) of the support piece 72 of the support 70 is fitted in the fitting recess 63 on the housing side. And can be supported upright. The support piece 72 includes a first bent piece 72a that rises upward from the bottom plate 71 and a second bent piece 72b that protrudes forward from the first bent piece 72a. The housing 62 is configured to fit into the fitting recess 63.
One of the characteristic structures of this support mechanism is that a part of the support piece 72, in particular, the bottom plate 71 does not hide the housing front surface 62a. Therefore, the appearance design of the electronic device is not deteriorated, or the layout of the operation unit and the display unit 65 is not hindered.
[0008]
Even in the case of an electronic device having a support mechanism having the above-described configuration, when the electronic device alone is lying on the side as shown in (a), the fitting recess 63 is located on the back surface 62d, which may cause a problem in appearance. Absent. Further, when the electronic device 61 is erected on the placement surface 80 with the bottom surface 62c facing downward, the electronic device 61 is assembled by fitting the second bent piece 72b of the support tool 70 into the fitting recess 63. (C) and (d), and the bottom plate 71 may be placed on the mounting surface 80 in this state. When the support tool 70 is detached from the housing, the second bent piece 72b may be extracted from the fitting recess 63.
Therefore, according to the support mechanism according to this reference example , the support can be attached and detached without using a special fixing means such as a screw, so that not only the workability is good but also the cost is advantageous.
In addition, the structure of the said support mechanism is an example, and is not necessarily limited to this. That is, for example, FIG. 2 (a) is a rear view of a fitting recess constituting a support mechanism according to another embodiment of the present invention , (b) is an internal front view, (c) is an internal perspective view, and (d). FIG.
A characteristic configuration of the support mechanism according to this embodiment is that a pinching mechanism 90 that holds and holds the second bent piece 72b of the support piece 72 in the fitting recess 63 is provided. In this example, two clamping mechanisms 90 are provided adjacent to each other on the left and right sides, and further, as shown in FIGS. 3 (a), (b), and (c), the second bent piece 72b corresponds to each clamping mechanism 90. However, the present invention is not limited to this.
The clamping mechanism 90 includes a tongue piece 91 that is configured to be elastically deformable in the vertical direction by bending a part of the back surface 62b of the casing 62 into the inside of the casing. A click feeling is generated on the upper surface of the tongue piece 91. A small protrusion 92 for projecting is provided. The tongue piece 91 provided with the small protrusion 92 constitutes an elastic click piece. Above the tongue piece 91, a ceiling piece 93 extending inside the housing is provided with a predetermined gap, and the gap between the tongue piece 91 and the ceiling piece 93 is an empty space into which the second bent piece 72b is inserted. 94.
According to the support mechanism of this embodiment, when the support piece 72 is attached to and detached from the space 94 of the fitting recess 62, the small protrusion 92 generates a click feeling with the second bent piece 72b. It is possible to know the correct mounting at the time of mounting.
[0009]
Next, FIG. 4 is an exploded perspective view showing a configuration example of a wall-mounted support mechanism for detachably attaching a thin electronic device according to the present invention to a vertical wall surface. This support mechanism is configured to detachably support a supported portion provided on the back surface 62 b of the housing 62 of the electronic device 61 by a support tool 101 fixed to the wall surface 100.
The supported portion of the housing 62 includes at least two first fitting recesses 102 formed side by side on the back surface 62b of the housing, and a second fitting formed below the first fitting recess. And a recess 103.
The support 120 is made of, for example, a sheet metal, and has a flat plate-like base 121 fixed to the wall surface 100, and at least two first locking protrusions protruding forward from an appropriate position of the base 121, for example, an upper end edge. 122, and a second locking projection 123 protruding forward from a base portion (for example, a lower end edge) below the first locking projection 122. Further, brackets 124 that are bent and projecting in an L shape are provided on both side edges of the base 121, and the bases 121 are mounted by screwing screws 126 to the wall surface 100 through holes 125 provided in the brackets 124. Pre-fixed to the wall.
Each first locking projection 122 has a one-to-one correspondence with each first fitting recess 102 on the housing side, and can be fitted. The first locking protrusion 122 includes a base piece 122a that protrudes forward from the base 121 and a free end piece 122b that protrudes upward from the base piece 122a. The second locking projection 123 has a plate-like shape that protrudes horizontally, and can be fitted in a corresponding relationship with the second fitting recess 103 on the housing side.
[0010]
The feature of the support mechanism according to this embodiment is that each first fitting protrusion 122 of the support tool is fitted in each first fitting recess 102 of the housing, and then each first fitting is fitted. The second locking protrusion 123 is fitted into the second fitting recess 103 by rotating the lower part of the casing rearward (wall surface side) around the fitting recess 102 (free end piece 122b). The configuration is as described above. With this configuration, even if an upward force is applied to an electronic device in a wall-mounted state, it does not easily fall off.
As shown also in FIG. 5, the first fitting recess 102 has a locking hole 102a on its inner ceiling surface, and by engaging a free end piece 122b protruding upward into the locking hole 102a. The electronic device can be rotated backward about the locking hole 102a.
Further, the second fitting recess 103 may be a recess capable of pressing and holding the second locking projection 123 in a pinched state as shown in FIG. 5, or as shown in FIG. It is good also as a structure provided with the pinching mechanism (the tongue piece 91 and the elastic click piece).
As described above, the electronic device including the second fitting recess 103 can be wall-mounted using the support tool 120, and can be set up using the support tool 70 for standing as shown in FIG. It becomes possible to install.
[0011]
In the support mechanism having the above configuration, the procedure for locking the electronic device 61 to the support 120 is as shown in FIG. That is, first, as shown in (a), the upper part of the electronic device is inclined so as to approach the wall surface, and the first locking protrusion 122 of the support 120 fixed to the wall surface 100 is moved to the first fitting on the housing side. Fit into the recess 102. At this time, the second locking projection 123 is in a positional relationship that cannot be fitted to the second fitting recess 103.
Subsequently, the electronic device is lowered so that the free end piece 112b enters the locking hole 102a as shown in FIG. In this state, the second locking projection 123 is in a positional relationship that can be fitted with the second fitting recess 103.
Subsequently, as shown in (c), the second engaging projection 123 is second fitted by rotating the lower part of the electronic device 61 rearward (wall direction) around the free end piece 112b. The recess 103 is fitted and fitted.
At this time, the vertical backlash between the second locking projection 123 and the fitting recess 103 is a, and between the first locking projection 122 and the first fitting recess 102, When the backlash dimension of the vertical direction is b, a <b, so that even if the electronic device is pressed upward, the engagement between the first locking protrusion 122 and the first fitting recess 102 There is no losing luck.
In other words, in the fitted and fitted state of FIG. 5C, the second locking projection 123 is more than the first dimension a that can move up and down in the second fitting recess 103. Since the moving distance b necessary for detaching the free end piece 122b from the fitting recess 102 (locking hole 102a) is larger, the electronic device 61 has moved upwards within the range of the dimension a. Even so, the free end piece 122b continues to be locked in the first fitting recess 102 (locking hole 102a).
In addition, when the bracket 124 protruding laterally from both side ends of the base of the support tool 120 protrudes from the side of the locked electronic device 61 and becomes visible from the front or oblique front, the appearance deteriorates. Therefore, the dimension in the width direction of the entire support 120 may be shortened so that the bracket 124 is hidden behind the electronic device supported by the bracket 124. However, in this case, the interval between the first locking projections 122 may be shortened, and the stability of supporting the electronic device may be reduced. Therefore, for example, as shown in FIGS. 6A and 6B, a cut-and-raised portion 130 that protrudes toward the back surface of the base 121 is provided, and a wall surface is formed using the screw hole 131 provided in the cut-and-raised portion 130. If the support tool is configured to be fixed to 100, the cut-and-raised portion 130 can be provided at a position where it cannot be visually recognized and fixed to the wall surface without reducing the base area.
Examples of the object that can be supported by the support mechanism of the present invention include, for example, a thin display, an air purifier, various remote control devices and the like in addition to the wireless LAN transceiver.
[0012]
【The invention's effect】
According to the present invention as described above, the support mechanism for use in the type of electronic device that can be wall-mounted to the wall surface, the appearance is degraded or in the state of hanging wall electronics, is upwardly electronic devices energized When it is done, it becomes easy to drop off from the wall surface, or by using a special fixing means such as a screw, problems such as a drop in detachability and an increase in cost can be solved at once, thereby increasing the commercial value.
That is, the present invention provides a first support mechanism provided on the back surface of the housing in a support mechanism that removably supports the housing of the electronic device having the supported portion on the back surface by a support member fixed to a substantially vertical wall surface. The first locking protrusions of the support members are respectively fitted in the fitting recesses, and then the lower locking protrusions are rotated by rotating the lower part of the housing backward about the first fitting recesses. Since the portion is configured to be fitted into the second fitting recess, even if an upward force is applied to the electronic device locked by the support, there is no possibility of dropping off. In addition, since a fixing tool such as a screw is not used, the detachability operability of the electronic device is not lowered, and an increase in cost can be avoided.
According to the present invention, since the clamping mechanism for clamping and holding the support piece or the second locking projection is provided in the fitting recess or the second fitting recess, sufficient holding force is provided. Thus, the electronic device can be fixed to the support.
According to the present invention, the elastic click piece that generates a click feeling when the support piece or the second locking projection is attached or detached is provided in the fitting recess or the second fitting recess. When the electronic device is mounted on the support, it can be easily known that the mounting has been completed, and the electronic device can be prevented from falling off due to a mounting failure.
