Description

【０００１】
【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、左右一対の外側板の間に、定型の地板及び天板の複数対と、１乃至複数の中側板とを連設することより、間口方向（横方向）に収納部を増設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、組立式の増連可能な収納家具として、木製の矩形状の天板、地板、及び側板のそれぞれ両端部に係合溝を形成し、断面がＬ字状の連結ブロックとＴ字状の連結ブロックと、十字状の連結ブロックとを前記天板、地板、側板の係合溝に係合させることにより、縦横方向に収納部分を増連させることが知られている（特許文献１）。
【０００３】
他方、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２）。

【０００５】
【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、天板、地板、側板は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。
【０００６】
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。
【０００７】
特許文献２の組立式収納家具では、複数の収納部を横に連増する場合には側板同士を左右に背中合わせに接続しなければならず、収納家具の左右中間部分における側板部分の板厚さが太くなり、外観が見苦しくなるという問題があった。
【０００８】
本発明の第１の目的は、任意の数だけ、収納部を横一列状に増連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、外観の優れた組立式収納家具を提供することである。
【０００９】
本発明の第２の目的は、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構成を工夫することにより、板同士のずれを生じさせず外観がすっきりとし、且つ強固で確実に着脱自在できるようにした組立式収納家具を提供することである。
【００１０】
【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、左右一対の外側板と、該両外側板の間に配置する１乃至複数の中側板と、１乃至複数の地板及び天板とを、互いに直交するように着脱自在に連結してなる組立式収納家具であって、前記各外側板、地板及び天板の前後側縁に沿って断面Ｌ字状の端段部を有し、前記中側板の前後側縁に沿って断面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側で高さが低く、内側で高い段付き状に形成されているものである。
【００１１】
そして、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、前記各板の端部の前記断面Ｌ字状の端段部及び断面Ｔ状の端段部は、それぞれ中空状の端嵌合部に形成し、前記各板の端部同士を連結するための連結部材には、前記各板の端嵌合部に嵌まる嵌入片を備えたものである。
【００１２】
また、請求項３に記載の発明は、請求項２に記載の組立式収納家具において、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。
【００１３】
さらに、請求項４に記載の発明は、請求項３に記載の組立式収納家具において、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。
【００１４】
請求項５に記載の発明は、請求項３または４に記載の組立式収納家具において、前記端用連結部材と増連用連結部材のいずれか一方には他方の部材に対して係脱する係合突起を有するものである。
【００１５】
請求項６に記載の発明は、請求項３乃至５のいずれかに記載の組立式収納家具において、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。
【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は本発明の組立式家具を横一列状に増連した状態を示す斜視図、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である。
【００１７】
図１に示すように、本発明に係る組立式収納家具１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は組立式収納家具１の奥行き寸法Ｄ（図１参照）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（図１参照）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より若干短く形成される。
【００１９】
［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。
【００２０】
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。
【００２１】
［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。
【００２２】
［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）。
【００２３】
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。
【００２４】
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。
【００２５】
［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。
【００２６】
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。
【００２７】
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。
【００２８】
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。
【００２９】
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。
【００３０】
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。
【００３１】
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。
【００３２】
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。
【００３３】
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。
【００３４】
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。
【００３５】
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）。
【００３６】
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）。
【００３７】
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。
【００３８】
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。
【００３９】
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。
【００４０】
［組み立て方法］
次に、図１、図２、図８及び図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。
【００４１】
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。
【００４２】
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。
【００４３】
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。
