【発明の属する技術分野】
本発明は、組立式収納家具の構成に係り、より詳しくは、左右一対の側板と、地板及び天板とで構成した枠体の上下中途部に構造棚板を連結して収納空間を上下に形成できるようにした組立式収納家具の構造に関するものである。
【０００２】
【従来の技術】
従来、組立式のキャビネットとして、左右一対の側板と地板及び天板との間に中間の棚板を複数配置する構成として、左右一対の外板の内面に縦長の棚受け部材をビス止めし、棚受け部材の同じ高さ位置の係止溝孔に棚板の左右両側縁を差込み支持させる構成が知られている（特許文献１）。
【０００３】
また、組立式戸棚における左右一対の側板の内面に前後一対の棚長の枠柱を固定し、前後一対枠柱間に前後に長い棚受け棒を水平状に固定し、この棚受け棒に中間の棚板の左右両側の係止部を載置するように構成したものが知られている（特許文献２）。
【０００４】
さらに、製造、保管、運搬、解体が容易で強度の高い枠体構造を有する組立式収納庫本体として、天板、地板及び左右側板は、それぞれ外壁部と、その外壁部の内側に外壁部と協働してその長さ方向に延びる中空状の補強部を備える。天板及び地板の左右端部と左右側板の上下端とを連結するコーナ連結部材は、天板、地板及び側板の奥行き寸法に略等しい長さの基片に互いに直交する方向に延びる嵌合片を備え、この嵌合片を、前記補強部の中空部内に嵌め入れた後、締結ねじにて固定するものが知られている（特許文献３）。

【発明が解決しようとする課題】
しかしながら、前記特許文献１に記載の組立式収納家具では、棚板の奥行き寸法を棚板（天板、地板）の奥行き寸法より短く形成し、また、家具の前面に２枚の引戸を配置するためには、天板、地板のそれぞれの前側縁に間口方向に長いレールを一体的に形成して、引戸の内面が棚板の前縁と干渉しないようにしており、棚板の前縁側に扉の装着できる構成ではなかった。
【０００７】
又前記特許文献２では中間の固定棚板の上下前側に引き戸を配置するためには、地板の上面前側に敷居レールを、天板の下面前側に鴨居レールをそれぞれ形成し、別途前記固定棚板の前縁に敷居部材と鴨居部材を固定しているので、部品点数が多くなると共に、開閉扉や抽斗の鏡板を家具の前側に配置することができない。
【０００８】
さらに、前記特許文献１及び２のいずれにおいても、背面板の左右両側縁を左右一対の側板の内面に縦長の溝内に落とし込み係止する構成であるから、地板、天板、左右側板を枠体に組み立てた後に背面板を後から着脱自在に取り付けすることができないという問題もあった。
【０００９】
特許文献３の組立式収納家具では、地板、天板、側板が単なる平板状であるため、この家具の背面を覆うための背面板を装着するときには、当該背面板を天板、地板、側板の各後縁の垂直面に直接当接させた状態で、且つ板の板厚さ部分にネジ止めする等して固定しなければならず、そうすると、背面板の４周縁が外に露出する状態になるから、当該４周縁の板厚部分の表面をきれいに化粧しなければ外観が悪くなると共に、家具としての奥行き寸法が背面板の板厚さ分だけ大きくなるという問題があった。
【００１０】
さらに、前記家具の収納部内に抽斗を配置した場合にも、当該抽斗の鏡板がその板厚さ分だけ家具の前面に突出して露出している状態になるので、外観が悪くなるという問題があった。
【００１１】
本発明の目的は、背面板や抽斗の鏡板、開閉扉を家具の後面や前面から突出させないように装着でき、外観の優れた組立式収納家具を提供することである。
【００１２】
【課題を解決するための手段】
前記目的を達成するため、請求項１に記載の発明の組立式収納家具は、左右一対の側板と、地板及び天板とにより枠体を構成する組立式収納家具であって、前記枠体で囲まれる収納空間を上下に仕切る１乃至複数の棚板を前記側板の内面に着脱可能または固定式に装着する一方、前記地板及び天板の前後側縁の少なくともいずれか一方に沿って断面Ｌ字状の端段部を有し、前記棚板の前後側縁の少なくともいずれか一方には、前記端段部と同じ向きに突出する断面Ｔ状の端段部を有し、前記断面Ｌ字状の端段部及び断面Ｔ状の端段部の向きは、それぞれ収納家具の前後端のいずれか一方で高さが低く、内側で高い段付き状に形成されているものである。
【００１３】
請求項２に記載の発明は、請求項１に記載の組立式収納家具において、前記側板の前後側縁の少なくともいずれか一方には、前記端段部と同じ向きに突出する断面Ｌ字状またはＴ状の端段部を有するものである。
【００１４】
請求項３に記載の発明は、請求項１または２に記載の組立式収納家具において、前記枠体の前面側の内周の端段部のうち高さの低い個所には、前記収納空間の前面側を塞ぐように、開閉扉または抽斗の鏡板を配置したものである。
【００１５】
請求項４に記載の発明は、請求項１乃至３のいずれかに記載の組立式収納家具において、前記枠体の後面側の内周の端段部のうち高さの低い個所には、前記収納空間の後面側を塞ぐように、背面板を着脱可能または固定式に装着したものである。
【００１６】
【発明の実施の形態】
次に、本発明を具体化した実施形態について図面を参照しながら詳述する。図１（ａ）及び図１（ｂ）は本発明の組立式家具の斜視図、図２は天板、地板、外側板、中側板、端用連結部材、増連用連結部材の斜視図、図３（ａ）及び図３（ｂ）は天板及び地板の断面図、図３（ｃ）は外側板の断面図、図４（ａ）は天板及び地板の内面側の平面図、図５（ａ）〜図５（ｄ）は中側板の種類別の断面図、図６（ａ）〜図６（ｄ）は端用連結部材の斜視図、図７（ａ）〜図７（ｄ）は増連用連結部材の斜視図、図８は地板と中側板とを端用連結部材及び増連用連結部材を使用して連結する場合の説明のための斜視図、図９（ａ）〜図９（ｄ）は中側板に端用連結部材及び増連用連結部材を嵌入した状態を示す図、図１０（ａ）〜図１０（ｃ）は地板と背面板との連結部を示す要部断面図、図１１は構造棚板の下面図、図１２は構造棚板の取り付け部の拡大断面図、図１３は収納家具の前後面が開放される場合の構造棚板の側断面図、図１４は構造棚板の後端を背面板にて覆う場合の構造棚板の側断面図である。
【００１７】
図１（ａ）及び図１（ｂ）に示すように、本発明に係る組立式収納家具１（以下、単に収納家具１という）は、左右一対の外側板２、２と、該両外側板２、２の間に配置する１乃至複数の中側板３と、１乃至複数の地板４及び天板５とを、互いに直交するように、端用連結部材６及び増連用連結部材７とを介して着脱自在に連結して増連可能なものである（但し、図１及び図２において一方の外側板は図示していない）。なお、収納空間を増設しない単位組立式収納家具とするときには、左右一対の外側板２、２と１つの地板４及び天板５と４つの端用連結部材６とにより構成されることになる。
【００１８】
本実施形態では、外側板２、中側板３、地板４及び天板５は薄い金属板を折り曲げる等して平面視矩形状に形成されており、各板２〜５の幅寸法Ｄは収納家具１の奥行き寸法Ｄ（図２参照）と同じに設定されている。また、端用連結部材６及び増連用連結部材７は、ＡＢＳ樹脂材やアルミダイカスト等からなる一体成形品であり、端用連結部材６及び増連用連結部材７の長さ寸法も組立式収納家具１の奥行き寸法Ｄと同じに設定されている。地板４及び天板５の長さ寸法Ｗは、単位組立式収納家具の間口方向寸法Ｗと略等しく（若干短く）設定される（図１及び図２参照）。外側板２及び中側板３の長さ寸法Ｈは、単位組立式収納家具の高さ寸法Ｈ１に略等しく（若干短く）形成される。
【００１９】
なお、図１の実施形態では、床面に支持枠台８を介して収納家具１を載置している。また、外側板２と中側板３との間の中途高さ位置に前面及び後面が開放された開放収納空間９を形成するため、後に詳述するような２枚の棚板（構造棚板）７０、７０を外側板２及び中側板３の各内面側に固定するものである。
【００２０】
［地板４及び天板５］
地板４及び天板５の基本形は、それぞれ広幅の平板１０の前後側縁に沿って断面略Ｌ字状の前後端段部１１、１２が形成されている（図３（ａ）参照）。この前端段部１１と後端段部１２は前記端用連結部材６の一部が嵌まり込む中空状の端嵌合部に形成されるものであって、補強部と兼用される。即ち、外側板２、地板４及び天板５の外面を構成する平板１０の間口方向に沿って延びる前後縁片を内方向に断面コ字状に折曲げた屈曲部１０ａを設ける（図１０（ａ）〜図１０（ｃ）参照）。他方、平板１０の内面にスポット溶接して固定する金属板製の前後端補強枠１３は平板１０の間口方向に沿って延び、断面Ｌ字状に屈曲された高さ寸法（Ｌ１）の低い端部１４が前記屈曲部１０ａに添設され、前記端部１４の奥側（収納家具１の奥行き側の内方）にて高さ寸法（Ｌ２）の大きい段付き部１５が折曲げ形成されている（図３及び図１０（ａ）〜図１０（ｃ）参照）。従って、前端段部１１と後端段部１２には略Ｌ字状の中空状の嵌合部が形成される。前後端補強枠１３、１３には補助嵌合部１８が一体形成されている。
【００２１】
また、前記平板１０の内面の略中央部には、家具の奥向き方向に長い断面コ字状の中央補強枠１６を家具１の間口方向に延びるように添設してスポット溶接にて固定し、該中央補強枠１６と平板１０とで囲まれた中空状の中央嵌合部１７を構成する。地板４及び天板５は同一形状であり、且つ前後端段部１１、１２も同じ寸法であり、収納家具１の奥行き方向に対称形状であるので、事実上、上下左右に反転させて共用できるものである。
【００２２】
［外側板］
外側板２の基本形は図３（ｃ）に示すが、地板４及び天板５の基本形と略同じであり（図３（ａ）参照）、外側板２の外面を構成する平板１０の上下方向に沿って延びる前後縁片を内方向に断面コ字状に折曲げた屈曲部１０ａを設ける。他方、平板１０の内面にスポット溶接して固定する金属板製の前後端補強枠１３は平板１０の上下方向に沿って延び、断面Ｌ字状に屈曲された高さ寸法（Ｌ１）の低い端部１４が前記屈曲部１０ａに添設され、前記端部１４の奥側（収納家具１の奥行き側の内方）にて高さ寸法（Ｌ２）の大きい段付き部１５が折曲げ形成されて、前端段部１１と後端段部１２には略Ｌ字状の中空状の嵌合部が形成される。また、前記平板１０の内面の略中央部には、家具の奥向き方向に長い断面コ字状の中央補強枠１６を家具の１の高さ方向に延びるように添設してスポット溶接にて固定し、該中央補強枠１６と平板１０とで囲まれた中空状の中央嵌合部１７が構成されている。外側板２は、前後端段部１１、１２も同じ寸法であり、収納家具１の奥行き方向に対称形状であるので、事実上、上下左右に反転させて左右両側の部分に共用できるものである。
【００２３】
［中側板］
中側板３の基本形は図５（ａ）に示すごとく、広幅（寸法Ｄ）の平板２０の略中央部にてコ字状に屈曲され、上下方向に延びる補強部２１と、該補強部２１と対向するようにスポット溶接された断面コ字状で同じく上下方向に延びる中央補強枠２２とで中央嵌合部２３が構成されている。そして、平板２０前後端縁に沿って上下に延びるように、略Ｔ字状の前端段部２４と後端段部２５とを設ける。この前端段部２４と後端段部２５とは、平板２０の前後縁片を内方向に断面Ｌ字状に折曲げた屈曲部２０ａと、平板２０の片面にスポット溶接して固定する金属板製の断面Ｌ字状に折曲げた前後端補強枠２６とにより構成される。そして、前記Ｔ字状の前後両端段部２４、２５は平板２０の間口前面に沿って延びる高さ寸法（Ｌ１）の低い端部２７と、該端部２７の奥側（収納家具１の奥行き側の内方）にて高さ寸法（Ｌ２）の大きい段付き部２８とにより形成されている。従って、段付き部２８と屈曲部２０ａによる段部の高さ寸法はＬ３（＞Ｌ２）となる。前端段部２４と後端段部２５とは略Ｔ字状の中空状の嵌合部が形成される（図２及び図５（ａ）〜図５（ｄ）参照）。
【００２４】
前記外側板２、地板４、天板５における前端段部１１と後端段部１２と、中側板３における前端段部２４と後端段部２５とは同一形状である。
【００２５】
そして、前記基本形の外側板２、中側板３及び地板４に対して、オプショナルな複数種類の断面コ字状の取付け枠２９ａ〜２９ｄが後述する方法で組み立て後に交換可能に取り付けられる。この取付け枠２９ａ〜２９ｄは詳細に図示しないが、地板４の上面を略平坦な同一平面にするために用いるときには、取り付け枠の中途には孔がなく、収納家具１内に抽斗（図示せず）を多段に配置したり、中間棚板を複数段にわたって配置するためには、棚板取り付け用の係止孔や抽斗のレール取り付け孔が、取付け枠２９の平坦部に適宜間隔で穿設されているものである。
【００２６】
［端用連結部材６及び増連用連結部材７］
次に、端用連結部材６及び増連用連結部材７の構成について説明すると、図６（ａ）〜図６（ｄ）は端用連結部材６の斜視図であり、断面略矩形の基体３０は、Ｗの長さを有して間口方向に延びる。基体３０の前後両端部には、それぞれ第１端嵌入片３１ａ，３１ｂと、第２端嵌入片３２ａ，３２ｂと、中央嵌入片３３ａ，３３ｂとが互いに直交する方向に突出するように設けられている。
【００２７】
断面Ｌ字状の第２端嵌入片３２ａ，３２ｂは地板４及び天板５における前後端の略Ｌ字状の中空状の嵌合部を有する前端段部１１と後端段部１２にそれぞれ左右方向（間口方向）から嵌入できるものである。第２端嵌入片３２ａ，３２ｂには、基体３０の前後端面方向に延びて低い高さの前端部１４内にきっちりと嵌まる薄板状の嵌入部３５ａと、高い高さの段付き部１５内にきっちりと嵌まる断面略矩形状のボス部３５ｂとが一体的に形成されている。
【００２８】
断面Ｌ字状の第１端嵌入片３１ａ，３１ｂは外側板２における前後端の略Ｌ字状の中空状の嵌合部を有する前端段部１１と後端段部１２にそれぞれ嵌入できるものであり、また、端用連結部材６と後述する増連用連結部材７とを背中合わせにした状態で、中側板３における断面Ｔ状の前端段部２４及び後端段部２５の一部に上下方向からきっちりと嵌入できるものである。
【００２９】
即ち、第１端嵌入片３１ａ，３１ｂには、基体３０の前後端面方向に延びる薄板状の嵌入部３４ａと、断面略矩形状のボス部３４ｂとが一体的に形成されている。
【００３０】
一方の中央嵌入片３３ｂは地板４及び天板５における中央嵌合部１７に対して横方向からきっちりと嵌入できるものであり、他方の中央嵌入片３３ａは外側板２における中央嵌合部１７に対して上下方向からきっちりと嵌入できる形態である。
【００３１】
また、中側板３における中央嵌合部２３に対しては、端用連結部材６と後述する増連用連結部材７とを背中合わせにした状態で、中央嵌入片３３ａと（後述する）増連用連結部材７における中央嵌入片４３ａとを上下方向からきっちりと嵌入できる形態である。なお、基体３０には中央嵌入片３３ａと第１端嵌入片３１ａ，３１ｂとの間においてこれらと同じ突出方向に第１補助係止ブロック３６、３６が設けられ、前記オプショナルな複数種類の断面コ字状の取付け枠２９ａ〜２９ｄをネジ止めする。また、第１補助係止ブロック３６と直交する方向に突出する第２補助係止ブロック３７は、地板４及び天板５における前後端補強枠１３に一体形成された補助嵌合部１８に嵌まるものである。なお、重量軽減のためにボス部３４ｂ，３５ｂ、第２補助係止ブロック３７及び中央嵌入片３３ａ，３３ｂを中空状に形成しても良い。
【００３２】
実施形態では、端用連結部材６は基体３０の長手方向の中央に対して左右対称形状に形成されている。従って、図６（ｂ）の姿勢（第１端嵌入片３１ａを基体３０の前部で上向きに突出し、且つ第２端嵌入片３２ａを基体３０の前部で左方向横向きに突出した姿勢）を基準にして示すと、図６（ｂ）は、図６（ａ）のものを中央嵌入片３３ｂの個所を中心にして第１端嵌入片３１ｂ及び第２端嵌入片３２ｂが図の手前になるように上下に１８０度回転させた状態である。図６（ｃ）は、図６（ａ）のものを基体３０の断面中心線回りに反時計方向に９０度回転させた状態である。さらに、図６（ｄ）は、図６（ａ）のものを中央嵌入片３３ａの個所を中心にして第１端嵌入片３１ｂ及び第２端嵌入片３２ｂが手前になるように水平に１８０度回転させた状態である。
【００３３】
端用連結部材６とほぼ同じ形態の増連用連結部材７は、Ｗの長さの有して間口方向に延びる細長い基体４０を有する。図７（ａ）〜図７（ｄ）に示すように、基体４０の前後両端部には、それぞれ第１端嵌入片４１ａ，４１ｂと、第２端嵌入片４２ａ，４２ｂと、中央嵌入片４３ａ，４３ｂとが互いに直交する方向に突出するように設けられている。また、実施形態では、増連用連結部材７も基体４０の長手方向の中央に対して左右対称形状に形成されている。
【００３４】
図７（ｂ）の姿勢（第１端嵌入片４１ａを基体４０の前部で上向きに突出し、且つ第２端嵌入片４２ａを基体４０の前部で左方向横向きに突出した姿勢）を基準にして示すと、図７（ｂ）は、図７（ａ）のものを中央嵌入片４３ｂの個所を中心にして第１端嵌入片４１ｂ及び第２端嵌入片４２ｂが図の手前になるように上下に１８０度回転させた状態である。図７（ｃ）は、図７（ａ）のものを基体４０の断面中心線回りに反時計方向に９０度回転させた状態である。さらに、図７（ｄ）は、図７（ａ）のものを中央嵌入片４３ａの個所を中心にして第１端嵌入片４１ｂ及び第２端嵌入片４２ｂが図の手前になるように水平に１８０度回転させた状態である。
【００３５】
断面Ｌ字状の第２端嵌入片４２ａ，４２ｂは地板４及び天板５における前後端の略Ｌ字状の中空状の嵌合部を有する前端段部１１と後端段部１２にそれぞれ左右方向（間口方向）から嵌入できるものである。第２端嵌入片４２ａ，４２ｂには、基体４０の前後端面方向に延びて低い高さの前端部１４内にきっちりと嵌まる薄板状の嵌入部４５ａと、高い高さの段付き部１５内にきっちりと嵌まる断面略矩形状のボス部４５ｂとが一体的に形成されている。
【００３６】
第１端嵌入片４１ａ，４１ｂは、基体４０から前記第２端嵌入片４２ａ，４２ｂの突出方向と直交する方向に一体的に突出する断面略矩形状のものであって、端用連結部材６と増連用連結部材７とを背中合わせにした状態で、中側板３における断面Ｔ状の前端段部２４及び後端段部２５の一部、即ち前記屈曲部２０ａの中空部内に上下方向からきっちりと嵌入できるものである（図８、図９（ａ）及び図９（ｂ）参照）。
【００３７】
増連用連結部材７に互いに直交する方向に突出する一方の中央嵌入片４３ｂは地板４及び天板５における中央嵌合部１７に対して横方向からきっちりと嵌入できるものであり、他方の中央嵌入片４３ａは、端用連結部材６と増連用連結部材７とを背中合わせにした状態で、端用連結部材６における中央嵌入片４３ａと共に中側板３における中央嵌合部２３に対して上下方向からきっちりと嵌入できる形態である（図８、図９（ａ）及び図９（ｄ）参照）。
【００３８】
また、基体４０には中央嵌入片４３ａと第１端嵌入片４１ａ，４１ｂとの間においてこれらと同じ突出方向に第１補助係止ブロック４６、４６が設けられ、前記オプショナルな複数種類の断面コ字状の取付け枠２９ａ〜２９ｄをネジ止めする。また、第１補助係止ブロック４６と直交する方向に突出する第２補助係止ブロック４７は、地板４及び天板５における前後端補強枠１３に一体形成された補助嵌合部１８に嵌まるものである。なお、重量軽減のためにボス部４４ｂと第１端嵌入片４１ａ，４１ｂ、第２補助係止ブロック４７及び中央嵌入片４３ａ，４３ｂを中空状に形成しても良い。
【００３９】
前記端用連結部材６と増連用連結部材７における中央嵌入片３３ａ，４３ａ、第１補助係止ブロック３６，４６の片面には、固定用の締着ネジ５０の皿状頭部が突出しないようにするためのＶ字状の凹溝５１が形成され（図６、図７参照）、且つ締着ネジ５０用のねじ込み用下孔５２が穿設されている（図６、図７、図９参照）。外側板２、中側板３、地板４、天板５、取付け枠２９ａ〜２９ｄには、前記ねじ込み用下孔５２に対応する個所に中心孔を有する皿状の凹部５３が形成されている（図４（ａ）、図４（ｂ）参照）。この各凹部５３の直径は前記凹溝５１の幅寸法に略等しく形成され、凹溝５１が凹部５３の取り付け時の案内の機能を果たす。
【００４０】
さらに、端用連結部材６と増連用連結部材７とを、中央嵌入片３３ａと中央嵌入片４３ａ同士及び第１端嵌入片３１ａ，３１ｂと第１端嵌入片４１ａ，４１ｂ同士がそれぞれ背中合わせに連設するときに、これらの片の突出方向に端用連結部材６または増連用連結部材７のいずれか一方が他方に対してずれ移動しないように、端用連結部材６または増連用連結部材７のいずれか一方の基体３０、４０の当接面（背中合わせの面）に係合突起５４を設ける。その実施形態の一つとしては、図９（ｂ）及び図９（ｄ）に示すように、中央嵌入片４３ａ及び第１端嵌入片４１ａ，４１ｂの基端を基体４０の背面から僅かの寸法ｅだけ突き出すように形成する一方、他方の中央嵌入片３３ａ及び第１端嵌入片３１ａ，３１ｂの基端は基体３０の背面から寸法ｅだけ内側に控えるようにして形成するものである。
【００４１】
［構造棚板］
次に、一対の外側板２、２間または外側板２と中側板３との間の中途高さ位置で水平に連結するための棚板としての構造棚板７０の基本形は、図１１及び図１４に示す。金属板からなる平板７１は、広幅（寸法Ｄ３＝Ｄ−Ｄ１）で、その略中央部の長さ寸法Ｗを地板４及び天板５の長さと等しく形成されている。
【００４２】
平板７１の略中央部にてコ字状に屈曲され、間口方向に延びる補強部７２と、該補強部７２と対向するようにスポット溶接された断面コ字状で同じく間口方向に延びる中央補強枠７３とを有する。そして、平板７１の前端縁に沿って間口方向に延びるように、略Ｔ字状の前端段部７４が設けられる。この前端段部７４の間口方向の長さＷ２は前記間口方向の寸法Ｗより大きく、前端段部７４の左右両側端の角部７４ａ、７４ａが外側板２及び中側板３の前端縁の高さの低い前端部１４（端部２７）の個所に当接できるように突出している（図１１参照）。
【００４３】
この前端段部７４は、平板７１の前縁片を内方向に断面コ字状に折曲げた屈曲部７１ａと、平板７１の片面にスポット溶接して固定する金属板製の断面コ字状に折曲げた前端補強枠７５とにより構成される。従って、前記Ｔ字状の前端段部７４は平板７１の間口前面に沿って延びる高さ寸法（Ｌ１）の低い端部７６と、該端部７６の奥側（収納家具１の奥行き側の内方）にて高さ寸法（Ｌ３）の大きい段付き部７７とにより形成されている。
【００４４】
前記平板７１の後縁片を断面略コ字状に屈曲させた屈曲部７８と、平板７１の片面にスポット溶接して固定する金属板製の断面コ字状に折曲げた後端補強枠７９とにより後端段部８０が形成されている。この後端段部８０は図１４に示すように高さ寸法がＬ３であり、且つ後端面に幅寸法Ｌ１のスリット８１が間口方向に沿って長く形成されている。なお、図１３に示す断面略Ｔ字状の後端縁部材８４は、高さ寸法Ｌ１の低い突出端部８４ａをスリット８１から後向きに突出させた状態でその高さの大きい部分を、前記後端段部８０の内面側に横から差込むことにより、略Ｔ字状の後端段部がオプションとして形成できる。
【００４５】
さらに、平板７０のうち、奥行き方向に沿う両側縁を下向きに直角に折曲げて支持片８２を構成し、この支持片８２の前後部位には下向きに開放された係止溝８３が切欠き形成されている（図１２、図１３及び図１４参照）。

次に、図１（ａ）、図１（ｂ）、図２、図８、図９（ａ）〜図９（ｄ）を参照しながら、本発明の組立式収納家具１の組立方法について説明する。まず、外側板２の上下位置において地板４及び天板５とを組むため、地板４及び天板５における間口方向の一側には端用連結部材６を奥行き方向に基体３０が延びるように並べる。次いで、端用連結部材６の横向きの第２端嵌入片３２ａ，３２ｂは地板４及び天板５における前後端の略Ｌ字状の中空状の嵌合部を有する前端段部１１と後端段部１２にそれぞれ横方向（間口方向）から嵌入すると共に、中央嵌入片３３ｂを地板４及び天板５における中央嵌合部１７に対してそれぞれ横方向から嵌入する。
【００４７】
前記外側板２と対峙する中側板３を立設する側では、地板４及び天板５における間口方向の他側には増連用連結部材７の基体４０を奥行き方向に延びるように配置し、横向き断面Ｌ字状の第２端嵌入片４２ａ，４２ｂは地板４における前後端の前端段部１１と後端段部１２の略Ｌ字状の中空状の嵌合部にそれぞれ横方向（間口方向）から嵌入し、中央嵌入片４３ｂを地板４における中央嵌合部１７に対して横方向から嵌入する。同様にして、天板５の他側においても、増連用連結部材７の基体４０を奥行き方向に延びるように配置し、横向き断面Ｌ字状の第２端嵌入片４２ａ，４２ｂは天板５における前後端の前端段部１１と後端段部１２の略Ｌ字状の中空状の嵌合部にそれぞれ横方向（間口方向）から嵌入し、中央嵌入片４３ｂを天板４５おける中央嵌合部１７に対して横方向から嵌入する。
【００４８】
次いで、地板４における前記一側の端用連結部材６の上向きの各第１端嵌入片３１ａ，３１ｂに対して外側板２における前端段部１１と後端段部１２の下側の嵌合部を嵌合し、同様に上向きの中央嵌入片３３ａに対して外側板２における中央嵌合部１７の下側を嵌合させる。
【００４９】
地板４における他側の増連用連結部材７の上向きの各第１端嵌入片４１ａ，４１ｂに対して中側板３における前端段部２４と後端段部２５の下側のＴ字状嵌合部（膨出部２０ａ側の中空部）を嵌合し、同様に上向きの中央嵌入片４３ａに対して中側板３における中央嵌合部２３の下側の一側に嵌合する。これらにより、外側板２及び中側板３は地板４の間口方向の両側に立設できる。この状態で、前記天板５の一側の端用連結部材６における下向きの各第１端嵌入片３１ａ，３１ｂを外側板２における前端段部１１と後端段部１２の上側の嵌合部に嵌め入れ、同様に下向きの中央嵌入片３３ａを外側板２における中央嵌合部１７の上側に嵌め入れる。天板５における他側の増連用連結部材７の下向きの各第１端嵌入片４１ａ，４１ｂを中側板３における前端段部２４と後端段部２５の上側のＴ字状の嵌合部（膨出部２０ａ側の中空部）に嵌め入れ、同様に下向きの中央嵌入片４３ａを中側板３における中央嵌合部２３の上側の一側に嵌入する。このようにして１つの収納空間が形成される。
【００５０】
次いで、前記立設した中側板３と対峙して横方向に収納部を増連するためには、予め、別の地板４の間口方向の一側（既に立設した中側板３に近い側）に端用連結部材６を配置し、横向き断面Ｌ字状の第２端嵌入片３２ａ，３２ｂは地板４における前後端の前端段部１１と後端段部１２の略Ｌ字状の中空状の嵌合部にそれぞれ横方向（間口方向）から嵌入し、中央嵌入片３３ｂを地板４における中央嵌合部１７に対して横方向から嵌入する。
【００５１】
この地板４の間口方向の他側（前記既に立設した中側板３から遠い側）に増連用連結部材７を配置し、横向き断面Ｌ字状の第２端嵌入片４２ａ，４２ｂは地板４における前後端の前端段部１１と後端段部１２の略Ｌ字状の中空状の嵌合部にそれぞれ横方向（間口方向）から嵌入し、中央嵌入片４３ｂを地板４における中央嵌合部１７に対して横方向から嵌入する。
【００５２】
前記と同様にして天板５においても、この天板５の間口方向の一側（既に立設した中側板３に近い側）に端用連結部材６を装着し、この天板５の間口方向の他側（既に立設した中側板３から遠い側）に増連用連結部材７を前記と同様に装着する。そして、増連すべき地板４の一側の端用連結部材６における上向きの各第１端嵌入片３１ａ，３１ｂを、既に立設している中側板３における前端段部２４と後端段部２５の下側の嵌合部（前後端補強枠２６側、略Ｌ字状の中空部）に嵌入し、同様に上向きの中央嵌入片３３ａを前記立設している中側板３における中央嵌合部２３の下側の一側に嵌入する。このとき、中央嵌合部２３の略半分の個所に前記中央嵌入片４３ａが既に嵌入しており、それに隣接させて中央嵌入片３３ａを強制的に嵌入する。同様に、Ｔ字状の中空部を有する前端段部２４と後端段部２５においても先に矩形状の第１端嵌入片４１ａ，４１ｂが嵌まっているから、Ｌ字状の第１端嵌入片３１ａ，３１ｂは、前端段部２４と後端段部２５の嵌合部（前後端補強枠２６側、略Ｌ字状の中空部）に嵌め入れられることになる。そして、前述したように、端用連結部材６または増連用連結部材７のいずれか一方の基体３０、４０の当接面（背中合わせの面）に係合突起５４を設けることにより、実施形態では図９（ｂ）及び図９（ｄ）に示すごとく、中側板３における中央嵌合部２３、前端段部２４、後端段部２５内に嵌まった端用連結部材６に対して増連用連結部材７を先に抜け出せないようにできる。
【００５３】
上述のようにして、外側板２、中側板３、地板４、天板５を端用連結部材６と増連用連結部材７とにより組み立てた後、締着ネジ５０にて、地板４、天板５、外側板２の各中央補強枠１６と中央嵌入片３３ｂ、４３ｂとを皿状の凹部５３の個所で固定し、中側板３に対しても中央嵌合部２３を構成する補強部２１と中央補強枠２２との皿状の凹部５３個所にて締着ネジ５０にて中央嵌入片３３ａ、４３ａを固定する。このようにして、多数の収納部を横一列状に増設できることになる。なお、最後に増設する地板４と天板５の間口方向の両端には、端用連結部材６、６を装着することになる。
【００５４】
従って、複数の収納部を横に連増する場合の中側板と天板及び地板の端部との連結のための連結部材の嵌入片が各板の端部の断面Ｌ字状の及び断面Ｔ状の中空状の端嵌合部に嵌まるので、板同士のずれを生じさせず外観がすっきりとし、且つ強固であり、着脱も確実に行えて組み立て作業が容易になるという効果を奏する。
【００５５】
また、前記連結部材は、前記各外側板の上下端部と地板及び天板の左端又は右端とを繋ぐ端用連結部材と、前記中側板の上下端部と地板及び天板の左端又は右端とを繋ぐために端用連結部材と背中合わせに連設使用する増連用連結部材とにより構成されているものであるから、端用と増連用の２種類の連結部材を準備するだけで簡単に収納部を増設できる。
【００５６】
さらに、前記各外側板、地板及び天板における収納家具の前後方向中途部には、内面側に突出して各板の端部方向に開放される中空状の中央嵌合部を有し、前記中側板には、その左右両側面に突出し、且つ上下に開放する中央嵌合部を有し、前記端用連結部材及び増連用連結部材は、前記各板の前後方向に沿って延びる基体に対して、前記中央嵌合部に嵌合する前後長手の中央嵌入片と、前記各端嵌合部に嵌合する端嵌入片とがそれぞれ直交する方向に突出形成されているものであるから、各連結部材における中央嵌入片を各板における中央嵌合部に嵌入するから、組み立て強度が一層強化される。そして、地板、天板、外側板及び中側板、並びに前記両連結部材を収納家具の奥行き方向に対称形状に形成すれば、両連結部材を各板の四隅に介して共用でき、部品点数を格段に少なくできるという効果を奏する。
【００５７】
互いに直交する方向に延びる各板２〜５の端部同士における前記各中央嵌合部と中央嵌入片とを締結ねじにより締結固定するものであるから、収納家具の組み立て強度がさらに強固になると共に、締結ねじが収納家具の内側に位置するから、良好な外観を有するという効果を奏する。
【００５８】
次に、構造棚板７０の取り付け作業について説明すると、予め、前記外側板２及び中側板３の各内面のうち、中央補強枠１６、２２及び補強部２１と前後端段部１１、１２の間に、オプションの断面コ字状の取付け枠２９ａ（〜２９ｄ）のうち、適宜のものを取り付け固定し、中央補強枠１６、２２または補強部２１の表面と取付け枠２９ａ〜２９ｄの表面とが同一平面になるようにしておく。
【００５９】
次いで、図１（ａ）、図１（ｂ）及び図１３に示すように、収納家具１の前面と後面とにわたって、上下一対の構造棚板７０、７０の間が開放された収納空間８６になるようにするには、各構造棚板７０の後端段部８０に後端縁部材８４を予め装着しておく。外側板２と中側板３との内面間に、各構造棚板７０を配置し、その左右両端の支持片８２、８２を前記取付け枠２９ａ（〜２９ｄ）の表面に当接させる。その場合、図１２に示すように係止用の頭付きビス８５を取付け枠２９ａ（〜２９ｄ）の表面に締着し、この頭付きビス８５の軸部に各構造棚板７０の支持片８２における係止溝８３を係止することで、当該構造棚板７０を前後方向に位置ずれせずに強固に取り付けでき且つ取外しも容易にできる。
【００６０】
各構造棚板７０、７０の上面を平面状に形成するためには、構造棚板７０における中央補強枠７３と、前端補強枠７５、後端段部８０との間の凹部にオプションの断面コ字状の取付け枠２９ａを嵌込めば良い。
【００６１】
組み立てられた収納家具１の前面及び背面には、図１（ａ）、図１（ｂ）、図５（ａ）〜図５（ｄ）、図１０（ａ）〜図１０（ｃ）及び図１３に示すように外側（収納家具の前後端側）で低い高さであり、且つ収納部の奥側（内側）で高さの高い段付き状の前端段部１１、２４と後端段部１２、２５とは囲み枠が形成されるから、前記上下の構造棚板７０、７０の前後面を除いた個所に、囲み枠の奥行き寸法Ｄ１（図１（ａ）、図１（ｂ）、図２、図３、図５及び図１０参照）に略等しい厚さの開閉扉６０や背面板６１、及び抽斗の鏡板６６、引き戸６７のそれぞれを、外側板２、中側板３、地板４、天板５の前後端面から突出させないようにして配置できる。
【００６２】
背面板６１を収納家具１の背面開口部内に固定する実施形態のうち、図１０（ａ）は、背面板６１の金属板材の周囲を内向きに屈曲させた周囲枠６２をビス６３にて低い高さの前端部１４（前端段部２４、後端段部２５）に締着したものである。図１０（ｂ）及び図１０（ｃ）の実施形態では、背面板６１の外面のみまたは周囲枠６２までクロス等の表装材６４を貼り付けたものである。
【００６３】
図１０（ａ）における二点鎖線で示すようにコ字状の屈曲部６５を背面板６１の４周縁のうちの一側縁に形成し、この屈曲部６５を外側板２、地板４、天板５、中側板３の背の高い段付き部１５（前後端補強枠２６、屈曲部２０ａ）に係止して、前記の個所のビス６３止めを省略することができる。
【００６４】
図１１及び図１４に示す実施形態では、上下一対の構造棚板７０、７０の後端縁に背面板６１を当接するように配置する場合であって、その場合には各構造棚板７０の後端段部８０から後端縁部材８４を予め外しておくことにより、構造棚板７０幅寸法（Ｄ３）は、外側板２及び中側板３の幅寸法ＤよりＤ１だけ短いので、収納家具１を組み立てた後に背面板６１を外側板２及び中側板３における後端段部１２、２５に嵌まり込むように装着でき、また取り外すことも簡単にできるのである。
【００６５】
図１３、図１４のように、外側板２及び中側板３の上下方向の中途部に前記の構成の構造棚７０を取り付けすることにより、組立式収納家具の強度も一層向上するのである。構造棚７０の左右両側端と外側板２及び中側板３の内面の部材とを別途の取り付け金具やボルト（ビス）を介して強固に固定的に取り付けるようにしても良い。収納空間を横に増連しない場合（単位収納家具の場合）には、左右の外側板２、２の間に前記構造棚７０を取り付けすることは勿論である。従って、本発明において側板とは、外側板２及び中側板３の両者の組み合わせを含む。
【００６６】
【発明の効果】
以上に詳述したように、請求項１に記載の発明の組立式収納家具は、左右一対の側板と、地板及び天板とにより枠体を構成する組立式収納家具であって、前記枠体で囲まれる収納空間を上下に仕切る１乃至複数の棚板を前記側板の内面に着脱可能または固定式に装着する一方、前記地板及び天板の前後側縁の少なくともいずれか一方に沿って断面Ｌ字状の端段部を有し、前記棚板の前後側縁の少なくともいずれか一方には、前記端段部と同じ向きに突出する断面Ｔ状の端段部を有し、前記断面Ｌ字状の端段部及び断面Ｔ状の端段部の向きは、それぞれ収納家具の前後端のいずれか一方で高さが低く、内側で高い段付き状に形成されているものである。
【００６７】
従って、本発明によれば、組立式収納家具の内部の収納空間を簡単に上下に仕切るようにできるものでありながら、背面板や抽斗の鏡板、開閉扉を家具の後面や前面から突出させないように装着でき、場合によっては上下一対の棚板間の収納空間を前後方向に開放したものを簡単に構成でき、外観の優れた組立式収納家具を提供することができるという効果を奏する。
【００６８】
請求項２及び３に記載の発明によっても、請求項１に記載の発明と同様の効果奏することができる。
【００６９】
請求項４に記載の発明は、請求項１乃至３のいずれかに記載の組立式収納家具において、前記枠体の後面側の内周の端段部のうち高さの低い個所には、前記収納空間の後面側を塞ぐように、背面板を着脱可能または固定式に装着したものであるから、背面板をその四周縁が収納家具の四周から見えないように嵌め込み式に装着できるという効果を奏する。

[0053]
After the outer plate 2, the middle plate 3, the main plate 4, and the top plate 5 are assembled by the end connecting member 6 and the additional connecting member 7 as described above, the main plate 4, the top plate 5, the central reinforcing frame 16 of the outer plate 2 and the central fitting pieces 33b and 43b are fixed at the place of the dish-shaped concave portion 53, and the reinforcing portion 21 constituting the central fitting portion 23 also for the middle side plate 3; The central fitting pieces 33a and 43a are fixed with fastening screws 50 at 53 places of the dish-shaped concave portion with the central reinforcing frame 22. In this way, a large number of storage units can be added in a horizontal row. End connecting members 6 are attached to both ends in the frontage direction of the base plate 4 and the top plate 5 to be added last.
[0054]
Therefore, when a plurality of storage sections are added laterally, the fitting pieces of the connecting member for connecting the middle side plate to the top plate and the end of the main plate are L-shaped and T-shaped at the end of each plate. Since it fits into the hollow end fitting portion of the shape, there is an effect that the appearance is clean and strong without any displacement between the plates, and it can be securely attached and detached and the assembling work is facilitated.
[0055]
Further, the connecting member is an end connecting member that connects the upper and lower ends of the outer plates and the left end or the right end of the base plate and the top plate, and the upper and lower ends of the middle plate and the left end or the right end of the base plate and the top plate. It is composed of a connecting member for end and a connecting member for increasing the number of stations to be used in a back-to-back manner to connect the two. Can be added.
[0056]
Further, the outer plate, the base plate, and the top plate have a hollow center fitting portion at a middle part in the front-rear direction of the storage furniture, which protrudes inward and is opened toward an end of each plate. The side plate has a central fitting portion projecting from both left and right side surfaces thereof and opening up and down, and the end connecting member and the additional connecting member are arranged on a base extending along the front-rear direction of each plate. The front and rear longitudinal fitting pieces to be fitted to the center fitting portion and the end fitting pieces to be fitted to the respective end fitting portions are formed so as to protrude in directions orthogonal to each other. Since the central fitting piece of the member is fitted into the central fitting portion of each plate, the assembling strength is further enhanced. If the base plate, the top plate, the outer plate and the middle plate, and the two connecting members are formed in a symmetrical shape in the depth direction of the storage furniture, the two connecting members can be shared via the four corners of each plate, and the number of parts can be significantly increased. The effect is that it can be reduced to a small amount.
[0057]
Since the central fitting portions and the central fitting pieces at the ends of the plates 2 to 5 extending in directions orthogonal to each other are fastened and fixed by fastening screws, the assembling strength of the storage furniture is further enhanced.
