【００１５】
【発明の実施の形態】
図１は本発明に係る入れ子式ラックＲを正立状態で示す斜視図、図２の（Ａ）はそのラックＲの正面図、（Ｂ）は（Ａ）のＶ−Ｖ線断面図、図３の（Ａ）はラックＲの右側面図、（Ｂ）はその背面図である。また図４の（Ａ）は図１の矢印イで示す部分の拡大図、（Ｂ）は図１の矢印ロで示す部分の拡大図、図５の（Ａ）は図１の矢印ハで示す部分の拡大図、（Ｂ）は図１の矢印ニで示す部分の拡大図である。図１において、１は左右の前柱、２は左右の後柱、３は４本の柱１，１，２，２の下端部に枠組み形成された積載床、４は左右の後柱２，２の上端面に亘って架設された後部上梁、５は前柱１の上端部と後部上梁４の上面端部とに亘って架設されたサイド上梁である。積載床３は、前後横梁６，７、左右縦梁８，８及び格子状の中間梁９からなり、中間梁９は、縦梁９₁と横梁９₂とを格子組みしたものである。
【００１６】
前柱１、後柱２、後部上梁４、サイド上梁５、積載床３の前後横梁６，７、左右縦梁８，８及び中間梁９（縦梁９₁と横梁９₂）は、夫々同じ太さの断面正方形に形成されている。前柱１及び後柱２は、図１５の（Ｄ）に示すように、断面コ字状（又は断面Ｃ字状）の前面側柱材１₁，２₁と断面長方形の背面側柱材１₂，２₂とを一体的に結合して断面正方形に形成されたもので、前面側柱材１₁，２₁の前面には、柱長手方向一定ピッチで金具係止孔１０が設けられている。このように各柱１，２が断面コ字状（又は断面Ｃ字状）の前面側柱材１₁，２₁と断面長方形の背面側柱材１₂，２₂とで形成されて、前面側柱材１₁，２₁側に金具係止孔１０が設けられているから、金具係止孔１０を設けたことによって柱としての強度が低下するようなことがない。
【００１７】
図２の（Ｂ）に示すように、左右の前柱１，１の内法間隔をＷ₁とし、左右の後柱２，２の外法間隔をＷ₂とすれば、Ｗ₁＞Ｗ₂で、Ｗ₁はＷ₂よりもわずかに広い。また、左右後柱２，２の内法間隔をＷ₃とし、積載床３の外法幅、つまり左右縦梁８，８の外法間隔をＷ₄とすれば、Ｗ₃＝Ｗ₄である。また、図２の（Ｂ）から分かるように、左右のサイド上梁５，５の内法間隔は、左右の前柱１，１の内法間隔Ｗ₁に略等しい。このような基本構造によって、このラックＲは、同じ構造のラックＲに対して入れ子式に収納（ネスティング）することができる（図９参照）。
【００１８】
本発明のラックＲの特徴の一つは、図４の（Ａ）及び図５の（Ａ）から分かるように、前柱１を積載床３の前横梁６の前面ａに対し柱１個分後退させて配置すると共に、前柱１の前面１ａ下端部に前柱１と同じ太さ（同じ大きさの断面形）の短寸柱１１を取り付け、この短寸柱１１の上端面に角錐台形状の収納用嵌合突起１２を突設すると共に、前柱１の上端面に同じく角錐台形状の積み重ね用嵌合突起１３突設し、そして前柱１の下端面には収納用嵌合突起１２及び積み重ね用嵌合突起１３が嵌合可能な嵌合穴１４を設けたことにある。前柱１の下端面の嵌合穴１４は図７の（Ａ）に示す。
【００１９】
また、図２の（Ａ）、図３の（Ａ）、及び図４の（Ａ），（Ｂ）から分かるように、前柱１の上端面１ｃに突設された積み重ね用嵌合突起１３の背面側に所要の隙間ｋを隔ててサイド上梁５の前端面５ａが位置し、このサイド上梁５の上面５ｃが積み重ね用嵌合突起１３の上端と略同一水平面に位置すると共に、サイド上梁５の下面５ｄが前柱１の上端面１ｃと同一水平面に位置し、またサイド上梁５は後端部が後部上梁４の上面４ｃに載置固定されているから、後部上梁４の上面４ｃはサイド上梁５の上面５ｃよりも積み重ね用嵌合突起１３の高さ分だけ低位置にあり、しかして図４の（Ｂ）に示すようにサイド上梁５の内側面５ｅと後部上梁４の上面４ｃとの交差部に積み重ね用柱下端部嵌合部１７が形成される。サイド上梁５の前端部は、前柱１の背面上端部に取り付けられた取付台片１５上に固着されており、またサイド上梁５の後端面から後部上梁４の背面４ｂに亘って補助板１６が固着してあって、この補助板１６が上記積み重ね用柱下端部嵌合部１７の背面部を位置規制する規制板となる。
【００２０】
図２の（Ｂ）から分かるように、積載床３は、４本の柱１，１，２，２の下端から、当該積載床３を構成する各梁６〜９の太さ（柱１，２の太さと同じ）の約２倍分の長さ上方へ隔たった位置に積載床３の下面が位置するように設けられ、この積載床３の下面と接地床面Ｆ（図２の（Ａ）参照）との間に一定の空間部Ｓ１が形成され、この空間部Ｓ１は、具体的に、左右前柱１，１の内側面１ｅ，１ｅ、後柱２，２の前面２ａ，２ａ及び積載床３の下面によって囲まれる空間部で、何も突起物がない。
【００２１】
図１、図４及び図５に示すように、左右各サイド上梁５の下面５ｄの両端部に角筒状の金具受け１８が取付部片１９を介して前後方向に開通するように取り付けられ、積載床３の左右各縦梁８の外側面８ｆの両端部には金具受け１８と同様に前後方向に開通する角筒状の金具受け２０が取り付けられている。サイド上梁５側の金具受け１８は、図１２及び図１３に示すように、連結すべきラックＲ，Ｒの左右側面同士を隣接させて、隣合うラックＲ，Ｒの隣合う金具受け１８，１８に亘って連結金具２１を係着することにより、ラックＲ，Ｒの側面同士を連結するためのものである。尚、これらの金具受け１８及び金具受け２０は、後述するサイドガードＳＧを取り付ける場合にも使用される。
【００２２】
また図１及び図４に示すように、左右後柱２，２の互いに対向する内側面２ｅ，２ｅには夫々上下両端部に上下方向に開通する細長角筒状の金具受け２２が設けられている。この金具受け２２は、図１２に示すように、連結すべきラックＲ，Ｒの背面同士を隣接させて、隣合うラックＲ，Ｒの隣合う金具受け２２，２２に亘って連結金具２３を係着することにより、ラックＲ，Ｒの側面同士を連結するためのものである。尚、この金具受け２２は、後述する背面ガードＢＧを取り付ける場合にも使用される。
【００２３】
図６は、図１に示す正立状態のラックＲを逆立状態で示す斜視図であり、図７の（Ａ）は図６の矢印ホで示す部分の拡大図、（Ｂ）は図６の矢印ヘで示す部分の拡大図である。図７の（Ａ）から分かるように、前柱１の下端（図６や図７では上端となる）には積み重ね用嵌合突起１３が嵌合する嵌合穴１４が形成され、また前柱１の内側面１ｅと積載床３の前横梁６の背面６ｂと縦梁８の外側面８ｆとの間に形成される空間部の上面（図６や図７では下面となる）を塞ぐような前部平板状の前部受け金具２４が積載床３の上面（図６や図７では下面となる）と面一に取り付けられている。この逆立状態のラックＲは、図６に示すように、左右のサイド上梁５，５を床面に接地させて、安定状態となっている。
【００２４】
また、図７の（Ｂ）から分かるように、後柱２の前面２ａと積載床３の縦梁８の外側面８ｆとの交差部には、積載床３の上面（図６や図７では下面となる）に沿って面一状に延びる板部２５ａと、後柱２の外側面２ｆに沿った板部２５ｂとからなる後部受け金具２５が取り付けられている。２６は後柱２の内側面２ｅ下端部と積載床３の後横梁７の下面７ｄ端部とのコーナー部に取り付けられた補助金具で、開口部２６ａを有し、この補助金具２６の下端面は後柱２の下端面と面一である。
【００２５】
図６及び図７から分かるように、左右の前柱１，１及び後柱２，２の夫々下端面（図６や図７では上端面となる）は同一水平面上にあり、また前述したように、左右前柱１，１の内側面１ｅ，１ｅ、後柱２，２の前面２ａ，２ａ及び積載床３の下面（図６や図７では上面となる）によって囲まれる空間部Ｓ１（図２及び図３参照）内には何も突起物がない。
【００２６】
図８は、上記のような構成よりなるラックＲを正立状態で上下に積み重ねた状態を示す。この積み重ね状態では、下段側ラックＲにおける前柱１の上端にある積み重ね用嵌合突起１３が上段側ラックＲにおける前柱１の下端にある嵌合穴１４に嵌合すると共に、下段側ラックＲにおける後柱２の下端部が、サイド上梁５の内側面５ｅと後部上梁４の上面４ｃとのコーナー部に形成された積み重ね用柱下端嵌合部１７（図４の（Ｂ）参照）に嵌合し、それにより上段側ラックＲは前後方向及び左右方向の移動が制限されるから、前後方向の振動及び左右方向の振動が加わっても、上段側ラックＲが転落する可能性はきわめて少ない。
【００２７】
この場合、図４の（Ｂ）から分かるように、積み重ね用柱下端部嵌合部１７の背面部が補助板１６によって位置規制されているから、上段側ラックＲの前後方向移動がより確実に阻止される。ここでは、ラックＲを上下２段に積み上げた例しか示していないが、３段以上積み上げることが可能である。
【００２８】
図９は、不使用時に正立状態の一つのラックＲの内部に他のラックＲを収納した状態を示す。この正立収納状態においては、上段側ラックＲが下段側ラックＲに対し柱１，２の１本分だけ前方へ移動した状態で下段側ラックＲ内に収容されて、上段側ラックＲにおける前柱１の下端嵌合穴１４が下段側ラックＲの短寸柱１１の収納用嵌合突起１２に嵌合されると共に、後柱２が下段側ラックＲの後部受け金具２５の板部２５ａ及び縦梁８の上面（図５及び図７参照）上に載置される。従って、前後方向の振動及び左右方向の振動が加わっても、上段側ラックＲが離脱することはない。
【００２９】
図１０は、ラックＲを逆立状態で上下に積み重ねた状態を示す。この逆立積み重ね状態では、下段側ラックＲの前柱１の嵌合穴１４に上段側ラックＲの前柱１の積み重ね用嵌合突起１３が嵌合すると共に、上段側ラックＲの積み重ね用柱下端部嵌合部１７（図４参照）に下段側ラックＲの後柱２の下端部（図１０では上端部）が嵌合し、上段側ラックＲは、前後方向及び左右方向の移動が制限され、前後方向の振動及び左右方向の振動が加わっても、上段側ラックＲが転落することは殆どない。
【００３０】
図１１は、不使用時に逆立状態の一つのラックＲの内部に他のラックＲを収納した状態を示す。この逆立収納状態において、上段側ラックＲは、下段側ラックＲに対し柱１，２の１本分だけ後方へ移動した状態で、この下段ラックＲの上に被さるようにして入れ子式に収納されて、上段側ラックＲの前柱１の嵌合穴１４に下段側ラックＲの短寸柱１１の収納用嵌合突起１２が嵌合すると共に、下段側ラックＲの後柱２の下端（図１１では上端）が上段側ラックＲの後部受け金具２５の板部２５ａ及び縦梁８（図５及び図７参照）で支持される。従って、正立収納時と同様に、前後方向の振動及び左右方向の振動が加わっても、上段側ラックＲが離脱することはない。
【００３１】
図１２の（Ａ）は、互いに隣合うラックＲ，Ｒ同士を連結金具２１，２３によって連結する場合を示す。同図の（Ｂ）は、連結金具２３を示す斜視図であり、同図の（Ｃ）は、（Ａ）の矢印トで示す部分の拡大図で、背面同士隣合うラックＲ，Ｒの金具受け２２，２２同士が連結可能に隣接した状態を示し、そして同図の（Ｄ）は、連結可能に隣接した両金具受け２２，２２に亘って連結金具２３を係着し、双方のラックＲ，Ｒを背面同士連結した状態を示す。連結金具２３は、金属板を把手部２３ａと本体部２３ｂとからなるＬ字状に折曲し、本体部２３ｂに切欠溝ｇを形成してなるもので、（Ｃ）及び（Ｄ）に示すように隣接した両金具受け２２，２２に本体部２３ｂの切欠溝ｇを差し込んで係着するようになっている。
【００３２】
図１３の（Ａ）は、左右側面同士隣合うラックＲ，Ｒの金具受け１８，１８同士が連結可能に隣接した状態ならびに連結金具２１を示し、同図の（Ｂ）は、連結可能に隣接した両金具受け１８，１８に連結金具２１を係着しようとしている状態を示し、同図の（Ｃ）は、両金具受け１８，１８に連結金具２１を係着し終えた状態を示す。この連結金具２１は、金属板をＬ字状に折曲して把手部２１ａと本体部２１ｂとを形成すると共に、本体部２１ｂの先端側を把手部２１ａとは逆向きにＬ字状に折曲し、本体部２１ｂを切欠溝ｇを介して二股状に形成してなるもので、（Ｃ）及び（Ｄ）に示すように隣接した両金具受け１８，１８に二股状本体部２１ｂを差し込んで係着し、それによって隣合うラックＲ，Ｒを左右側面同士連結するようになっている。
【００３３】
図１４は、正立状態で使用されるラックＲに中棚２７を取り付けた状態を示す図１と同様な斜視図である。図１５の（Ａ）は中棚２７の平面図、（Ｂ）は正面図、（Ｃ）は側面図、（Ｄ）は中棚２７の取付状態の要部を示す斜視図である。図１６の（Ａ）の(a) は図１５の（Ａ）の矢印リで示す部分の拡大図、(b) は同部分の側面図、(c) は同部分の正面図であり、また図１６の（Ｂ）の(a) は図１５の（Ａ）の矢印ヌで示す部分の拡大図、(b) は同部分の側面図である。
【００３４】
中棚２７は、前横桟２８と後横桟２９と左右縦桟３０，３０と格子状中桟６１とからなるもので、図１４に示すように、前後左右４本の柱１，１，２，２で囲まれる空間部の所要高さ位置に取り付けられる。また、この中棚２７は、図１４及び図１５の（Ａ）に示すように、外法幅、即ち左右縦桟３０，３０の外法間隔Ｗ₅が左右前柱１，１の内法間隔Ｗ₁よりも僅かに狭く、且つ前横桟２８の長さＬ₁が左右前柱１，１の外法間隔Ｗ₆と略等しく、尚且つ前横桟２８の後側面から後横桟２９の後側面までの距離Ｌ₂が前柱の前側面から後柱の前側面までの距離に略等しくなっている。また、中棚２７の後横桟２９及び前横桟２８の夫々両端部には、後柱２の前面２ａ及び前柱１の前面１ａに設けられた金具係止孔１０に係止可能な夫々Ｌ字状の係止金具３１，３２が取り付けられている。
【００３５】
しかして、この中棚２７の取付けにあたっては、中棚２７を水平状態のままでラックＲ内にその前面側より挿入し、図１４及び図１５の（Ｄ）に示すように、後横桟２９の後側面両端部を左右後柱２，２の夫々前面２ａ，２ａに当接させて係止金具３１，３１を左右後柱２，２の係止孔１０，１０に係止させ、前横桟２９の後側面両端部を左右前柱１，１の夫々前面１ａ，１ａに当接させて係止金具３２，３２を左右前柱１，１の係止孔１０，１０に係止させることにより、中棚２７をラックＲ内の所要高さ位置に簡単容易にして迅速に取り付けることができる。また、この中棚２７を使用することにより、ラックＲ内部を上下に仕切ってラックＲの内部を有効に使用することができる。
【００３６】
図１７は、ラックＲの左右側面側にサイドガードＳＧを取り付け、背面側に背面ガードＢＧを取り付けた状態を示す。尚、図１７では、逆立状態のラックＲにサイドガードＳＧ及び背面ガードＢＧを取り付けているが、ラックＲは正立状態でもよい。図１８の（Ａ）は背面ガードＢＧを示す斜視図、（Ｂ）は（Ａ）の矢印ルで示す部分の拡大図である。図１９の（Ａ）はサイドガードＳＧを示す斜視図、（Ｂ）は（Ａ）の矢印オで示す部分の拡大図、（Ｃ）は（Ａ）の矢印ワで示す部分の斜視図である。
【００３７】
背面ガードＢＧは、図１８に示すように、周枠３３と格子状中桟３４とからなるもので、周枠３３の左右両側の夫々上下両端には、係止片３５ａが下向きに突出した横向きＬ字状の係止金具３５を備え、各係止金具３５の係止片３５ａが、後柱２の内側面に設けられた金具受け２２に係止されるようになっている。しかして、背面ガードＢＧの取付けにあたっては、この背面ガードＢＧを左右後柱２，２と後部上梁４と積載床３の後横梁７との間の空間部に配置して、周枠３３の両側にある係止金具３５の係止片３５ａを、後柱２の各金具受け２２に対しその上方より係止させればよい。この背面ガードＢＧは、ラックＲを上下逆にしても取付け可能である。
【００３８】
サイドガードＳＧは、図１９に示すように、周枠３６と格子状中桟３７とからなるもので、周枠３６の上端側にはその左右両端部に、係止片３８ａが上向きに突出した横向き略Ｓ字状の係止金具３８，３８を備え、周枠３６の下端側にはその左右両端部に、同様な係止片３９ａが下向きに突出した横向き略Ｓ字状の係止金具３９，３９を備えている。尚、係止金具３８は、周枠３６と略同一平面状に取り付けてあるが、係止金具３９は、取付片４０を介して周枠３６の内側へ寄った位置に取り付けられている。
【００３９】
しかして、サイドガードＳＧの取付けに際しては、このサイドガードＳＧを、前柱１と後柱２とサイド上梁５と積載床３の縦梁８との間の空間部に配置して、図１７に示すように、係止金具３８の係止片３８ａを、サイド上梁５に設けてある前後方向に開通する金具受け１８に対しその前後方向に挿入して係止させ、また係止金具３９の係止片３９ａを、積載床３の縦梁８に設けてある前後方向に開通する金具受け２０に対し夫々前後方向に挿入して係止させることにより、サイドガードＳＧを取り付けることができる。
