【０００６】
【発明の実施の形態】
図１乃至図１１に示す一実施例を参照にして本発明を詳細に説明する。
【０００７】
（１）発明の実施の環境
まず、図１乃至図３を参照に発明の実施の環境（収納箱１）について説明する。１は床面に設置されるスチール製の収納箱である。この収納箱１は、主に保存用文書を収納するために使用され、底板２と、この底板に一体的に固定された端面コ字状の側板３と、この側板３に一体的に固定された天板部材４と、天板部材４又は側板３にスライド自在に設けられた開閉戸５から成る。収納箱１は左右一対の把手を介して持ち運び可能である。
【０００８】
（２）底板
底板２は、矩形状の底壁部分２ａと、底壁部分２ａの四則縁から下方方向へそれぞれ連なった短い側壁部分２ｂ，２ｃ，２ｄとから成る。しかして、前壁に相当する短い部分２ｂは、開閉戸５の下端部を支持することができるように段差状に形成されている。また左右の側壁に相当する部分２ｃ，２ｃ及び底壁部分２ａの左右中央部には、小さな切欠部６，６が形成されている。
【０００９】
（３）側板
３ａ，３ａは左右の側壁で、これらの側壁３ａ，３ａの先端部の縁部は、内側に折り曲げ形成されている。３ｂは左右の側壁に連なっている後壁である。ところで、本実施例では開閉戸５用支持部材が側壁に取り付けられている。すなわち、８は上端部に小さな係合溝９を有する左右一対の支持板で、これらの支持板８は側壁３ａ，３ａの先端部の内壁面にそれぞれ固定さている。また１０は開閉戸５を案内する左右一対のガイドレールで、これらのガイドレール１０は、本実施例では天板部材の内側板１５に図示しない固着手段を介してそれぞれ固定されている。
【００１０】
（４）天板部材
図２で示すように、天板部材４は、大と小の二枚の板を一体的に結合することにより構成されている。すなわち、１５は大きい方の内側板で、この内側板１５は、天井部分１５ａと、天井部分１５ａの四則縁から下方へと連なった短い側壁部分１５ｂ，１５ｃ，１５ｄとから成る。しかして、前壁に相当する側壁部分１５ｂには開閉戸５の幅寸法に相当する戸受入れ用切欠部１６が形成されている。また内側板１５の中央には横長状切欠部１７が形成されている。また、天井部分１５ａの少なくとも対角線上の２個の隅角部１８，１８には、複数個のメネジ孔１９（本実施例では３個づつ）がそれぞれ形成されている。
【００１１】
一方、２０は小さい方の外側板で、この外側板２０は、上壁部分２０ａと、上壁部分の四則縁から下方へと連なった短い側壁部分２０ｂ，２０ｃ，２０ｄとから成る。しかして、上壁部分２０ａの左右中央部には、把手収納用の切欠部（収納部）２１，２１がそれぞれ対称的に形成されている。これらの切欠部２１の形状は、後述する把手の形状に対応して方形状に形成されている。
また上壁部分２０ａの少なくとも対角線上の２個の隅角部２２，２２には、図しない身近な操作具（例えばドライバー）が入り込むことが可能な操作具用貫通孔（合計２個）２３，２３が形成されている。さらに、少なくとも短い側壁部分２０ｃ，２０ｄ（本実施例では、前壁に除いた他の対辺の側壁２０ｃ，２０ｃ，２０ｄ）の二面接合部２４の近傍には、係合ロック片出入り用切欠部２５（合計６個）が形成されている。
【００１２】
（５）開閉戸
開閉戸５は、戸枠５ａと、この戸枠５ａ内に取り付けられたガラス５ｂと、前記戸枠５ａの上端部の左右に突設された一対の摺動軸２７，２７と、戸枠５ａの下端部の中央部に装着された開閉戸用ストッパー手段２８とから成る。前記摺動軸２７は、閉戸時に於いて、支持板８の係合溝９に係合し、また開戸時に於いて、開閉戸５を水平状態にして後壁３ｂ側に押し込むと、例えばガイドレール１０を滑動する。
【００１３】
（６）把手
ここで、図９乃至図１１を参照に左右一対の把手について説明する。３１は天板部材４の左右端部にそれぞれ固定される取り付けベース板である。この取り付けベース板３１は、内側板１５の内壁面と接合する一対のフランジ部３２，３２を有している。また外端部寄りの部位に一対の軸受け部３３，３３を有している。把手３４は軸受け部３３，３３に軸架された横軸３５を介して取り付けベース板に略９０度回動可能に設けられている。なお、本実施例の把手３４は、平面コ字状のカバー３４ａと、このカバー３４ａに固定された握り部３４ｂとから成る。また取り付けベース板３１の外端部には、任意形状（例えばＺ形状）の支板３６を介して係合棒３７が固定的に設けられている。このように係合棒３７と把手３４が一体的にセット化された取り付けベース板３１は、内側板１５の横長状切欠部１７の下方から嵌め込むようにして天板部材４に装着され、かつ、図示しない固着具を介して固定される。
【００１４】
（７）収納箱の連結構造
次に同一形態の収納箱１，１同士の連結構造（機構）について説明する。本発明の連結構造は、受け板、押え板、係合ロック片などの各構成部品が一つの部材にユニット化され、少なくとも２つ以上のユニット部材Ｘ（連結部材）が天板部材４の対角線上の隅角部１８，１８，２２，２２内にそれぞれ対称的に組み込まれる。これらの収納箱連結用ユニット部材Ｘは、同一形態の収納箱を左右又は／及び背中合わせに（背面側）並列した場合に適合する。
【００１５】
図４乃至図６は、収納箱連結用ユニット部材Ｘの一例を示す。４１は矩形状の受け板で、この受け板４１は、内側板１５の天井部分１５ａの隅角部１８，１８に固定される。４２は受け板４１の一つ角部に形成されたネジ用貫通孔である。４３はネジ用貫通孔４２の近傍に形成された係合ロック片用軸孔である。４４ａ，４４ｂ，４４ｃは、係合ロック片のクリック感を彷彿させるために、軸孔４３の同心円上に形成された複数個（本実施例では３個）の係合小孔である。例えば一つの係合小孔４４ａに対する他の係合小孔４４ｂの位置は、軸孔４３の中心点を基準にすると、それぞれ１３５度の角度に設定されている。
【００１６】
次に４５は受け板４１に軸支された係合ロック片４５で、この係合ロック片４５は受け板４１の上面にスライド可能に装着されている。しかして、４６は円盤状の基端部で、この基端部４６の下面には軸孔４３に係合する突起軸４７が形成されている。一方、４８は基端部４６の上面に突出形成されたコイン形状の係合部で、この係合部４８は上方に位置する押え板５５の嵌合孔に遊嵌合する。係合部４８は上面から軸心方向に身近な操作具（ドライバー、コインなど）の端部が係合するマイナス溝４８ａを有している。
【００１７】
４９は前記突起軸４７の付近に突設された小突起で、この小突起４９は係合ロック片４５を所定角度（本実施例では１３５度）回動すると、各係合小孔にそれぞれ選択的に係合する。５０は基端部４６から半径方向へと延伸したロックアームで、このロックアーム５０は、本実施例では、碇形状或いはＴ字型形状に形成されている。したがって、ロックアーム５０は、先端部に左右一対のフック部５０ａ，５０ａを有している。またロックアーム５０は、先端部寄りの部位に左右一対の膨らみ部５０ｂ，５０ｂを有している。
【００１８】
前述した押え板５５は、受け板４１と対向するように内側板１５の天井部分１５ａの隅角部１８に固定され、かつ、外側板２０の隅角部２２，２２の内面に対向又は接合している。すなわち、５６は受け板４１と対向する矩形状の押圧壁で、この押圧壁５６と受け板４１との間には、係合ロック片４５が水平方向へ回動するのに十分な空間がある。この押圧壁５６の一つの角部付近には、前述した嵌合孔５７が形成されている。
【００１９】
５８は嵌合孔５７の外側に位置する支柱で、この支柱５８は一つの角部５５ａの下面に固定されている。５９は前記角部５５ａ及び支柱５８に形成されたネジ用貫通孔である。なお、前記支柱５８と同様の円筒型支柱５８Ａは、ユニット部材Ｘを組み込んでいない角部内にそれぞれ組み込まれかつビス止めされている（図１０を参照）。
【００２０】
しかして、押え壁５６の支柱５８が設けられた側の直交する二辺６０，６１には側壁が設けられていない。これに対し、これらの二辺６０，６１に対向する各辺には側壁６２，６２が設けられている。そして、各側壁６２，６２の一端部には、固着具６３用のネジ孔６４を有する取り付け部６５，６５がそれぞれ連設している。
【００２１】
６７は係合ロック片４５の係合部４８に嵌合する環状の板バネである。この板バネ６７は、図５で示すように係合ロック片４５の基端部４６の上面と押え板５５の押圧壁５６の下面との間に介在する。
【００２２】
上記構成に於いて、収納箱１の角部（隅角部）にユニット部材Ｘを取り付ける場合には、前述したように天板部材４の対角線上の隅角部１８，１８，２２，２２内にそれぞれ対称的に組み込む必要がある。
【００２３】
そこで、まず、天板部材４の内側板１５に外側板２０を固定する前に、ユニット部材Ｘを内側板１５の隅角部１８，１８に載置する。図５で示すように、この場合係合ロック片４５は外れないように軸孔４３と嵌合孔５７を介して受け板４１と押え板５５にサンドイッチ状に挟持されている。また、板バネ６７も係合部４８に嵌合している。
【００２４】
次に押え板５５のネジ孔６４，６４を内側板１５のメネジ孔１９，１９に合わせる。次にユニット部材Ｘ側のネジ孔と内側板１５側のメネジ孔とが一致したならば、長い方の固着具６９を、支柱５８のネジ用貫通孔５９及び受け板４１のネジ用貫通孔４２に通し、内側板１０のメネジ孔１９に螺合させる。また短い方の固着具６３，６３も押え板５５のネジ孔６４，６４にそれぞれ通し、内側板１０のメネジ孔１９に螺合させる。そして、最後に外側板を適宜に固定する。
上記のように天板部材４の対角線上の隅角部に組み込まれたユニット部材Ｘの係合ロック片４５は、たとえばドライバーを係合部４８の溝４８ａに係合して回すと、内部空間を通過して２７０度回転する（図４参照）。
【００２５】
したがって、係合ロック片４５は、押え壁５６の直交する二辺６０，６１から選択的に突出可能である。なお、係合ロック片４４が板バネ６７のバネ力に抗して１３５度回転すると、その小突起４９が係合小孔４４ａ，４４ｂ，４４ｃに落ち込み、その場で停止すると共に、「クリック感」が彷彿される。
【００２６】
【実施例】
係合ロック片４５の基端部４６には溝４８ａを有する係合部４８が突設されているが、この部分は設計変更可能である。例えば基端部４６に起立可能を操作片（摘み）を軸支しても良い。このような場合には、操作具は不要であり、係合ロック片４５を回転する際には摘みを引き上げて操作する。またバネ部材の一例としての板バネ６７は、係合ロック片４５の基端部４６の下面側に設けることも可能である。
【００２７】
【発明の効果】
以上の説明から明らかなように、本発明にあっては、次に列挙するような効果がある。
（１）図７で示すように、収納箱１，１を横方向に並列した場合には、例えば開閉戸５側のユニット部材Ｘの係合ロック片４５を押え壁５６の一辺６０から突出させると、左側（隣）の収納箱１の出入り用切欠部２５内へと入り込み、フック部５０ａが天板部材４の角部（本実施例では支柱）に係合する。
（２）また図８で示すように、収納箱１，１同士を背中合わせにして並列した場合には、例えば後壁３ｂ側のユニット部材Ｘの係合ロック片４５を押え壁５６の一辺６１から突出させると、後（隣）の収納箱１の出入り用切欠部２５内へと入り込み、フック部５０ａが天板部材４の角部（本実施例では支柱）に係合する。
（３）したがって、同一形態の収納箱１，１を横方向に並列した場合のみならず、背中合わせにして並列した場合にも、単に係合ロック片４５を所定角度回転させるだけで、収納箱同士の連結を容易に行うことができる。そして、多数の収納箱を左右・前後・上下に並列すると、安定した大型の書棚を簡単につくることができる。
（４）また、例えば天板部材の貫通孔２３に臨む係合ロック片４５の溝に操作具を係合して当該係合ロック片を回転させると、並列状態に配設された収納箱同士の連結状態が簡単に解消する。そこで、把手を起立させ、収納箱を所望の場所へと持ち運びすることができる。
（５）主たる構成部品がユニット化されているので、天板部材の隅角部内に容易に組み込むことができる。
