Description

【０００１】
【発明の属する技術分野】
本発明は、フォークリフトにより搬送を行うことができる大型の組立容器に関するものである。
【０００２】
【従来の技術】
従来から、大型の容器としては木製の容器が知られており、この大型の木製の容器内に収納物を収納した状態で搬送するに当たっては、容量が大きく且つ重量が重いため木製の容器をパレットに載置してフォークリフトにより搬送を行うようにしているが、木製の容器はパレットと一体化していないため、パレットへの載置やパレットから降ろす作業が必要であり、また、大型の木製の容器は空の状態で保管や搬送する場合、広いスペースを取り、これらの理由により、物流コスト、保管コストが高くなるという問題がある。また、大型の木製の容器内に収納物を入れたり、出したりするには容器が大型であるため、作業者が大型の木製の容器の上開口縁部に載ったり、あるいは中に入った状態で側板を越して収納物の出し入れを行わなければならず、作業がきわめて面倒で、手間がかかるという問題がある。
【０００３】
そこで、本出願人はパレットの上面の４辺に側板を配置し、側板同士が直角に隣接するコーナ部分において一方の側板の端部に設けた略櫛歯状の噛合部と他方の側板の端部に設けた略櫛歯状の噛合部とを着脱自在に噛み合わせ、両側板の噛合部に設けた連結孔及びパレットに設けた連結孔に連結棒を挿通してナットにより螺合する組立容器を実公平５−１６１０６号として出願している。
【０００４】
このものは連結棒を外すことで容易に分解できるようになっており、分解することで搬送コストや保管コストを低下できるようにしている。
【０００５】
しかし、この従来例にあっては、直角に隣接する側板の略櫛歯状の噛合部同士を噛み合わせた状態における連結棒によるパレットへの連結と、各側板の下面に突設した立設用の嵌合突起をパレットの各辺部の上面に形成した嵌合凹部に嵌合するという取付け構成を採用しているため、４つの側板を噛合部同士の噛み合わせにより四角形に組み立てた状態で、各側板の嵌合突起をパレットの嵌合凹部に嵌合させるという手順をとらなければ、パレットの４辺に側板を建て込むことはできないものである。いいかえれば、３つの側板をコ字状に組み立ててパレットの３辺に建て込んだ後で、残りの一つの側板を取付けようとしても、噛合部同士の噛合わせは水平方向からの嵌め込み作業によりおこなわなければならないが、嵌合突起と嵌合凹部との嵌合は垂直方向からの嵌め込みとなり、両者を同時に行うことは不可能であり、したがって、３つの側板をコ字状に組み立ててパレットの３辺に建て込んだ後で、残りの一つの側板を取付ることなどできないものである。
【０００６】
また、上記従来例にあっては、３つの側板をコ字状に組み立ててパレットの３辺に建て込んだ後で、残りの一つの側板を取付ることができないのみならず、３つの側板をコ字状に組み立ててパレットの３辺に建て込むとともに、残りの一つの側板は一端部のみをコ字状に組み立てて建て込んだ側板の一つの端部に連結棒により連結し、他方の端部は連結棒による連結を解除してフリーにしたとしても、従来例の噛合部の端部は隣接する側板の端面に邪魔されることなく回動できるような形状となっておらず、したがって、一つの側板を回動して開くことで、収納物の出し入れを容易とするという構成にできないものである。しかも、上記のように、嵌合突起と嵌合凹部とは垂直方向に嵌合する必要があるため、この点でも従来例のものは一つの側板を回動して開き且つ回動して閉じ、連結棒で連結するということなどできないものである。
【０００７】
上記の理由により従来例のものは使用時にはパレットの４辺に側板を立設して容器状に組み立てた状態とする必要があり、このため大型の組立容器内への収納物の出し入れに当たっては、作業者が大型の組立容器の上開口縁部に載ったり、中に入った状態で収納物の出し入れを行わなければならず、依然として作業性が悪いという問題があった。
【０００８】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、大型の組立容器において簡単な構成で使用時には側板の一つを回動自在に開いて組立容器内に収納物を簡単に出し入れでき、しかも、非使用時には簡単に分解してコンパクトにできて、搬送、保管のスペースに当たって大きなスペースを取らないようにできる組立容器を提供することを課題とするものである。
【０００９】
【課題を解決するための手段】
上記課題を解決するために本発明に係る組立容器は、フォークリフトのフォークの爪が挿入されるフォーク挿入部１を有するパレット２の上面部の４辺に同一形状の側板３を配置し、この同一形状の４つの側板３の両端部の側板３の略巾内に、それぞれ、突出長さが側板３の略巾と略同じ長さとなり且つ先端部に弧面部６が形成された軸受け部４と軸受け部４が突設しない平坦な凹み部７とを上下方向に形成し、各側板３の中間部分の下部にロック部材収納部１６を形成して該ロック部材収納部１６にロック部材２３を上下移動自在に収納配置し、側板３の内側を平面に形成し、側板３の外側を縦横リブで形成し、該縦横リブで形成した側板３の外側において上端部から下端部にわたる複数の縦リブを設けると共にこの縦リブ間の間隔が狭い部位と縦リブ間の間隔が広い部位を設け、側板３の中央部のロック部材収納部１６の両側の部位を上記縦リブ間の間隔が狭い部位とし、パレット２の四隅部に取付け用孔部８を設けるとともにパレット２の４辺の各中間部分にロック溝１５を設け、側板３同士が直角に隣接するコーナー部分において一方の側板３に設けた先端部に弧面部６が形成された軸受け部４と他方の側板３に設けた先端部に弧面部６が形成された軸受け部４とを上下にずらして配置し、一方の側板３の軸受け部４を他方の側板３の凹み部７に嵌め込み且つ一方の側板３の凹み部７に他方の側板３の軸受け部４を嵌め込んだ状態で回転軸５を上下の軸受け部４に挿入して上下の軸受け部４同士を回動自在に連結するとともに該回転軸５の下端部をパレット２の取付け用孔部８に挿入して該回転軸５をパレット２に対して着脱自在に連結し、さらに上記ロック部材２３を下方に引き下ろしてパレット２のロック溝１５に嵌め込んで側板３の中間部分をロックして、パレットの上面部の４辺にそれぞれ側板が起立姿勢で配置された組立状態とし、この組立状態において側板３の一端部の軸受け部４を回転軸５から離脱させ且つ該側板３の中間部分をパレット２にロックしているロック部材２３を上方に引き上げてロックを解除した状態で、該側板３の他端部の軸受け部４が、該軸受け部４とこれに隣接する他の側板３の軸受け部４とを連結し且つ下端部がパレット２の取付け用孔部８に連結されている回転軸５を中心に回動自在となるようにして成ることを特徴とするものである。このような構成とすることで、非使用時には側板３を取り外すことでコンパクトにすることができて、搬送、保管に当たってスペースをとらないようにできるものであり、また、使用時には同一形状の４つの側板３を組み立ててパレット２の４辺に建て込むことで組立容器Ａを構成し、この組立容器Ａ内に収納物を収納した状態でパレット２をフォークリフトで搬送することで簡単に移動できるものであり、さらに側板３の内側を平面に形成し、側板３の外側を縦横リブで形成し、該縦横リブで形成した側板３の外側において上端部から下端部にわたる複数の縦リブを設けると共にこの縦リブ間の間隔が狭い部位と縦リブ間の間隔が広い部位を設け、側板３の中央部のロック部材収納部１６の両側の部位を上記縦リブ間の間隔が狭い部位としているので、各側板３の中間部分は上記縦リブ間の間隔が狭い部位で挟まれたロック部材収納部１６に収納したロック部材２３によってパレット２に連結されることで中間部分が外側に膨れたり、あるいは内側に凹んだりするのを防止できるようになる。また、組立容器Ａ内に収納物を出し入れする際には同一形状の４つの側板３のうち一つの側板３の一端部を回転軸５から外してフリーにした状態で該側板３の他端部の軸受け部４を回転軸５を中心として回動して開くことで、組立容器Ａ内への収納物の出し入れを行うことができ、収納物の出し入れが終わると、該側板３を回動して閉じるとともに一端部の軸受け部４を隣接する側板３の一端部の軸受け部４に対して上下にずらして位置させ、この状態で回転軸５により両軸受け部４をパレット２に取付けることで簡単に側板３を閉じてパレット２に取付けることができるものである。そして、側板３の両端部の側板３の略巾内に、それぞれ、突出長さが側板３の略巾と略同じ長さとなり且つ先端部に弧面部６が形成された軸受け部４と軸受け部４が突設しない平坦な凹み部７とを上下方向に形成してあるので、上記のように回転軸５を中心として側板３の他端部の軸受け部４を回動して開くに当たり、支障なく側板３を回動して開閉できるものである。
【００１１】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１２】
組立容器Ａは図１、図２に示すように合成樹脂製の４つの側板３を合成樹脂製のパレット２の上面部の４辺にそれぞれ着脱自在に立設配置することで構成するものである。
【００１３】
パレット２は平面視正方形状又は平面視長方形状をしており、添付図面に示す実施形態では平面視正方形状の例が示してある。パレット２にはフォークリフトのフォークの爪が挿入されるフォーク挿入部１が設けてあってパレット２の側面に側方に開口している。パレット２の四隅部には上下に貫通する取付け用孔部８が形成してあり、この取付け用孔部８の上部は大径孔部８ａとなり、下部は大径孔部８ａに連通した小径孔部８ｂとなっている。
【００１４】
取付け用孔部８には図４に示すようにボルト９を下方から挿入してあり、ボルト９の上部にナット１０を螺合してあり、ナット１０を締め付けることで、ボルト９の頭部９ａを小径孔部８ｂの下端部開口の外周縁部に当てると共にナット１０をワッシャを介して大径孔部８ａの下端部と小径孔部８ｂの上端部とを連設する段部１１に押し付け、これによりボルト９を取付け用孔部８に取付けてある。このようにして取付けられたボルト９はナット１０よりも上部の部分が大径孔部８ａ内に位置していてパレット２の上面よりも上方に突出しないようにしてある。また、ボルト９の頭部９ａは取付け用孔部８の下方に突出しているが頭部９ａの外周はパレット２の四隅部に設けたスカート部１２により覆ってあって外部から見えないようにしてある。
【００１５】
また、パレット２の４辺の各中間部分にはそれぞれ図５に示すようなロック溝１５が形成してあり、ロック溝１５の溝底には排水孔１５ａが形成してある。
【００１６】
図６乃至図８に示すように、側板３は両端部にそれぞれ軸受け部４が設けてある。ここで、側板３の端面には上下方向の複数箇所に軸受け部４が突設してあり、側板３の端面の上下方向の軸受け部４を突設しない部分が凹み部７となっている。つまり、側板３の端面部には上下方向に軸受け部４と凹み部７とが交互に設けてある。軸受け部４は側板３の端面の略巾内において端面から突出しており、したがって、側板３の両端部に軸受け部４を設けたといえども軸受け部４は側板３の表面又は裏面に対して交差する方向に突出することなく、側板３の平板状態を保持していて組立容器Ａを分解して多数の側板３を面接触で重ねてコンパクトにできるようになっている。
【００１７】
側板３の一端部に設けた軸受け部４は他端部に設けた凹み部７に対応する高さ位置となっており、また、側板３の他端部に設けた軸受け部４は一端部に設けた凹み部７に対応する高さ位置となっている。
【００１８】
軸受け部４には上下方向に貫通する孔１３が設けてある。図６乃至図８に示す実施形態では側板３の両端部にそれぞれ上下方向に３個の軸受け部４と凹み部７とを交互に設けてあるが、両端部の３個の軸受け部４のうち上下２個の軸受け部４はいずれも筒体により構成してあって筒体内が上下に貫通する孔１３となっているが、中間に位置する軸受け部４は表面側に開口する水平断面Ｕ字状をしたＵ字状部１４ａと裏面側に開口する水平断面Ｕ字状をしたＵ字状部１４ｂとを上下に交互に一体に連設して構成してあり、表面側に開口するＵ字状部１４ａと裏面側に開口するＵ字状部１４ｂとを上下に一体に連設することで上下に貫通する孔１３が構成されるものである。
【００１９】
ここで、中間に位置する軸受け部４を筒体により構成してもよいが、中間に位置する軸受け部４を筒体により構成すると、合成樹脂により成形する際に、中間の筒体を成形するための金型構成が複雑となるが、上記のように中間に位置する軸受け部４を表面側に開口するＵ字状部１４ａと裏面側に開口するＵ字状部１４ｂとを上下に一体に連設して上下に貫通する孔１３を構成することで、表側と裏側とに金型を開く構成にして中間に位置する軸受け部４を成形することができることになる。
【００２０】
側板３の表面側の中央部の下部にはロック部材収納部１６が形成してある。ロック部材収納部１６は図１１に示すように、表面側から奥側に凹んだ溝部１７を形成し、この溝部１７の上部のみを表面側に開口させるとともに溝部１７の表面側を前遮蔽部１８により閉塞し、更に、溝部１７の下部の表裏方向（前後方向）の中間部を仕切り部１９により仕切って溝部１７の下部を上下に開口する前溝部１７ａと後溝部１７ｂとに仕切ってある。後溝部１７ｂの後部上端部には係止段部２０が形成してある。また、溝部１７の上部の両側には抜け止め突起２１が突設してあり、更に、溝部１７の上部の後面にはく字状をした係止溝２２が設けてある。
【００２１】
ロック部材２３は図１３に示すようなもので、垂直な脚部２４の上部にロ字状をした操作部２５が形成してあり、操作部２５の前面部は脚部２４の前面よりも前方に少し突出していて該突出部分の下面が当たり部２６となっている。また操作部２５の両側面部には突部３０が突設してある。操作部２５の上端部から断面Ｌ字状をした背方突出部２７が一体に突設してあり、背方突出部２７の縦片の下端部から下にいくほど背方となるように斜め下方に向けて弾性を有する第１係止片２８と弾性を有する第２係止片２９とが連出してある。第１係止片２８は背方突出部２７の縦片の両側下端部から連出してあって先端部に係止爪２８ａが設けてあり、第２係止片２９は背方突出部２７の縦片の中央下端部から連出してあって連出長さが第１係止片２９よりも短く且つ背面部がく字状をした係止突起２９ａとなっている。
【００２２】
上記の構成のロック部材２３は図１１（ｃ）のようにロック部材収納部１６の溝部１７内に表面側から嵌め込んである。この場合、ロック部材２３の脚部２４が溝部１７の下前部の前溝部１７ａ内に上下移動自在に嵌め込んであり、また、突部３０が抜け止め突起２１の背面側に当たってロック部材２３が前方に抜けないようになっており、また、第１係止片２８の係止爪２８ａが係止段部２０に弾性的に係止してロック部材２３が図１１（ｃ）の状態で上方に移動して溝部１７の上部の表面側の開口から抜けないようになっている。また、第２係止片２８のく字状をした係止突起２９ａがく字状をした係止溝２２に弾性的に係止していてロック部材２３を図１１（ｃ）の状態に保持している。この状態ではロック部材２３の脚部２４の下端は側板３の下端よりも下方に突出しないように設定してあり、非使用時に不用意に脚部２４の下端が下方に突出して破損しないようにしてある。
【００２３】
パレット２の上面部の４辺にそれぞれ側板３を起立姿勢で配置して隣接する側板３の端部同士とパレット２とを着脱自在に回転軸５により取付けることで上方が開口した図２に示すような組立容器Ａを組立形成するものである。
【００２４】
ここで、回転軸５は図９に示すようなもので、金属製の円筒体５ａの下端部にナット部５ｂを埋設固着し、円筒体５ａの上端部に円筒体５ａよりも大径の鍔部５ｃを固着し、鍔部５ｃの上面に操作用突部５ｄを突設したものである。
【００２５】
しかして、前述の側板３をパレット２の上面部の４辺に立て、側板３の端部に設けた軸受け部４を隣接する側板３の端部に設けた凹み部７内に嵌め込むことで、隣接する側板３の軸受け部４同士を上下にずらして多段に配置し、上下多段の軸受け部４の孔１３を上下に連通させるとともに、パレット２の取付け用孔部８の上端開口に連通させる。この状態で、最上段の軸受け部４の孔１３から回転軸５を挿入し、パレット２の取付け用孔部８の大径孔部８ａ内に回転軸５の下端部を挿入して回転軸５の下端部に設けたナット部５ｂを大径孔部８ａ内に位置するボルト９の上部に螺合し（操作用突部５ｄを指で摘んで回転操作することで螺合操作をする）、鍔部５ｃを最上段の軸受け部４の上面に押接することで、回転軸５により隣接する側板３の軸受け部４同士を連結するとともにパレット２に連結することで、組立容器Ａを簡単に組立形成するものである。この場合、回転軸５を上下多段の軸受け部４の孔１３に挿通して、操作用突部５ｄを指で摘んで回転操作するだけで簡単に隣接する側板３を連結すると共にパレット２に連結することができて、組立操作性が優れているものである。この組立状態においては、ロック部材２３の操作部２５を下方に引き下ろす操作をし、係止突起２９ａを係止溝２２から抜けさせ、図１２（ａ）に示すように、脚部２４をロック溝１５に嵌め込んでロックするものである。この場合、当たり部２６が前遮蔽部１８の上端部に当接して図１２（ａ）のロック状態においてロック部材２３が下方に移動しないようになっており、また、く字状をした係止突起２９ａが係止段部２０に弾性的に係止してロック部材２３が図１２（ａ）のロック状態で上方に移動しないようになっている。このロック状態では側板３は両端部だけでなく中間部分もパレット２に連結されて中間部分が外側に膨れたり、あるいは内側に凹んだりするのを防止するようになっている。
【００２６】
ここで、組立容器Ａ内に収納物を出し入れするには４つの側板３のうちの一つの側板３の一端部の軸受け部４を回転軸５から外し、また、該当する側板３の中間部をパレット２にロックしているロック部材２３を上方に引き上げて図１２（ｂ）の状態にしてロックを解除し、この状態で当該側板３の他端部を回転軸５を中心に回動することで図３のように側板３を開いて組立容器Ａの一側面を開口させ、この開口部３１から収納物を出し入れするものである。
【００２７】
一つの側板３を他端部の軸受け部４に挿通する回転軸５を中心に回動するには軸受け部４の先端部が隣接する側板３の端面である凹み部７の奧面に当たらないようにする必要がある。このため、本発明においては、側板３の一方の軸受け部４を回転軸５から脱離させてフリーにした状態で該側板３の他方の軸受け部４が回転軸５を中心に回動自在となるように該他方の軸受け部４の先端部に該先端部が隣接する別の側板３の端面に当たるのを避けるための弧面部６を形成している。添付図面に示す実施形態においては側板３の端面の上下方向に側板３の略巾内において突設する軸受け部４と軸受け部４が突設しない凹み部７とを形成しているので、軸受け部４の先端部の内面側を当該軸受け部４が回動する際に隣接する別の側板３の凹み部７の奧面に当たるのを避けるための弧面部６を設けておけば、側板３を閉じた時における側板３の端部間に隙間が生じないようにすると共に側板３を支障なく回動することができるものである。このように軸受け部４の先端部の内面側を弧面部６とするに当たっては、図８のように軸受け部４の先端部を平面視略半円形の弧面部６としてもよく、また、図１８のように軸受け部４の先端部を平面視略１／４円形の弧面部６としてもよいものである。
【００２８】
側蓋として回動させるために側板３の一端部を回転軸５から外すには、回転軸５を取付け時とは逆方向に回動して回転軸５を上方に抜き取り、側蓋として回動させようとする側板３を当該側板３の他端部側を回転軸５を中心に回動して当該側板３の一端部の軸受け部４を隣接する側板３の一端部の軸受け部４から離し、その後、先ほど取り外した回転軸５を隣接する側板３の一端部の軸受け部４の孔１３に挿入して回転軸５の下端部のナット部５ｂを大径孔部８ａ内に位置するボルト９の上部に螺合することで、図３のように回転軸５により隣接する側板３の軸受け部４のみをパレット２に連結しておくものである。
【００２９】
図３に示すように一つの側板３を回動した状態における組立容器Ａ内への収納物の出し入れが終わって再び組立容器Ａとして組立る場合には、側蓋として回動するために使用した側板３の自由端となっている一端部側と対応する隣接する側板３の端部をパレット２に連結している回転軸５を外し、その後、当該側板３の端部の軸受け部４と側蓋として回動するために使用した側板３の端部の軸受け部４とを上下にずらして位置させ、組立時と同様にして回転軸５により隣接する軸受け部４同士を連結するとともにパレット２に連結し、更に、側蓋として利用していた側板３に取付けているロック部材２３を操作して図１２（ａ）のロック状態とするものである。
【００３０】
組立容器Ａ内に収納物を収納した状態で、組立容器Ａのパレット２に設けたフォーク挿入部１にフォークリフトのフォークを挿入して持ち上げた状態で移動させ、トラック、貨車、船等に載せて搬送するものである。
【００３１】
ここで、組立容器Ａ内に収納物を収納した状態で必要に応じて図１４のように組立容器Ａの上開口部に上蓋３２を被せ、バンド３３により組立容器Ａと上蓋３２とを結束してもよいものである。
【００３２】
一方、組立容器Ａの非使用時には４つの回転軸５を外して側板３同士の連結、側板３とパレット２との連結を解除して分解するものである。回転軸５を外すにあっては、操作用突部５ｄを指で摘んで回転操作するだけで簡単に回転軸５の螺合を外して抜き取ることができて、簡単に隣接する側板３の連結を解除すると共にパレット２との連結を解除して分解できて、分解性が優れているものである。また、分解した場合、ボルト９の上端がパレット２の上面よりも上方に突出していないので、パレット９同士を積み重ねたりする際にもボルト９が支障にならないものである。また、各側板３に取付けているロック部材２３は上方に引き上げて図１１（ｃ）の状態としておく。このように分解することでコンパクトにして搬送したり、あるいは保管することで搬送や保管に要するスペースを小さくできるものである。
【００３３】
分解した上記の各部品は例えば、図１５のように、多数のパレット２を上下に積み重ね、更に、最上段のパレット２の上に多数の上蓋３２を積み重ね、必要に応じてバンドで結束し、最下段のパレット２をフォークリフトを利用して持ち上げることで移動させ、トラック、貨車、船等に載せて搬送したり、倉庫などに保管するものである。
【００３４】
また、多数の組立容器Ａを分解して搬送したり、保管したりする際に、大部分の組立容器Ａはすべての側板３を外して分解してパレット２は前述のようにまとめて積み重ねるが、任意の組立容器Ａは対向する一組の側板３を残して他の対向する一組の側板３を外したものとし、この対向する一対の側板３を残したパレット２の上面の上記一対の側板３間に図１６のように他の多数の側板３を並設配置するものである。そして、必要に応じて上蓋３２を被せて図１６（ｂ）のようにバンド３３で結束するものである。移動に当たっては、多数の側板３を載置しているパレット２をフォークリフトを利用して持ち上げることで移動させ、トラック、貨車、船等に載せて搬送したり、倉庫などに保管するものである。この場合、パレット２を平面視正方形状とし、４つの側板３を同一形状としておくことで、外した側板３がパレット２からはみ出したりすることなく、また、上蓋３２を被せるのに支障がないものである。
【００３５】
また、多数の回転軸５は図１７に示すように分解していない組立容器Ａ内に入れて上蓋３２を被せてバンド３３で結束するものであり、移動に当たっては、多数の側板３を載置しているパレット２をフォークリフトを利用して持ち上げることで移動させ、トラック、貨車、船等に載せて搬送したり、倉庫などに保管するものである。
【００３６】
なお、図１６、図１７において上蓋３２は破線で示している。
【００３７】
【発明の効果】
上記のように本発明の請求項１記載の発明にあっては、フォークリフトのフォークの爪が挿入されるフォーク挿入部を有するパレットの上面部の４辺に側板を配置し、各側板の両端部に、それぞれ、先端部に弧面部が形成された軸受け部と軸受け部が突設しない凹み部とを上下方向に形成し、各側板の中間部分の下部にロック部材を上下移動自在に配置し、パレットの四隅部に取付け用孔部を設けるとともにパレットの４辺の各中間部分にロック溝を設け、側板同士が直角に隣接するコーナー部分において一方の側板に設けた先端部に弧面部が形成された軸受け部と他方の側板に設けた先端部に弧面部が形成された軸受け部とを上下にずらして配置し、一方の側板の軸受け部を他方の側板の凹み部に嵌め込み且つ一方の側板の凹み部に他方の側板の軸受け部を嵌め込んだ状態で回転軸を上下の軸受け部に挿入して上下の軸受け部同士を回動自在に連結するとともに該回転軸の下端部をパレットの取付け用孔部に挿入して該回転軸をパレットに対して着脱自在に連結し、さらに上記ロック部材を下方に引き下ろしてパレットのロック溝に嵌め込んで側板の中間部分をロックして、パレットの上面部の４辺にそれぞれ側板が起立姿勢で配置された組立状態とし、この組立状態において側板の一端部の軸受け部を回転軸から離脱させ且つ該側板の中間部分をパレットにロックしているロック部材を上方に引き上げてロックを解除した状態で、該側板の他端部の軸受け部が、該軸受け部とこれに隣接する他の側板の軸受け部とを連結し且つ下端部がパレットの取付け用孔部に連結されている回転軸を中心に回動自在となるようにしてあるので、非使用時には側板を取り外してコンパクトにすることができ、これにより搬送、保管に際してスペースをとらないようにできるものであり、また、使用時には同一形状の４つの側板を組み立ててパレットの４辺に建て込むことで簡単に組立容器を構成し、組立容器内に収納物を収納した状態でパレットをフォークリフトで搬送することで簡単に移動できるものであり、さらに側板の内側を平面に形成し、側板の外側を縦横リブで形成し、該縦横リブで形成した側板の外側において上端部から下端部にわたる複数の縦リブを設けると共にこの縦リブ間の間隔が狭い部位と縦リブ間の間隔が広い部位を設け、側板の中央部のロック部材収納部の両側の部位を上記縦リブ間の間隔が狭い部位としているので、各側板の中間部分は上記縦リブ間の間隔が狭い部位で挟まれたロック部材収納部に収納したロック部材によってパレットに連結されることで中間部分が外側に膨れたり、あるいは内側に凹んだりするのを防止できるようになる。また、組立容器内に収納物を出し入れする際には同一形状の４つの側板のうち一つの側板の一端部を回転軸から外してフリーにした状態で該側板の他端部の軸受け部を回転軸を中心として回動して開くことで、組立容器内への収納物の出し入れを行うことができるものであって、組立容器が大型のものであっても組立容器内への収納物の出し入れ作業が組立容器の上開口部の縁部に作業者が載って出し入れ作業をする必要がなくて、簡単且つ迅速に収納物の出し入れ作業が行えるものであり、しかも、収納物の出し入れが終わると、該側板を回動して閉じるとともに一端部の軸受け部を隣接する側板の一端部の軸受け部に対して上下にずらして位置させ、この状態で回転軸により両軸受け部をパレットに取付けることで簡単に開いていた側板を閉じて取付けることができるものである。しかも、側板の両端部の側板の略巾内に、それぞれ、突出長さが側板の略巾と略同じ長さとなり且つ先端部に弧面部が形成された軸受け部と軸受け部４が突設しない平坦な凹み部７とを上下方向に形成してあるので、上記のように回転軸を中心として側板の他端部の軸受け部を回動して開くに当たり、簡単な構成で支障なく側板を回動して開閉できるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a large assembly container that can be transported by a forklift.
[0002]
[Prior art]
Conventionally, a wooden container is known as a large container, and when transporting a stored item in the large wooden container, the wooden container is palletized because of its large capacity and heavy weight. However, the wooden container is not integrated with the pallet, so it must be placed on the pallet and unloaded from the pallet. When storing and transporting in an empty state, it takes a large space, and for these reasons, there is a problem that the distribution cost and the storage cost increase. In addition, because the container is large enough to put or remove things in or out of a large wooden container, the operator is placed on or inside the upper opening edge of the large wooden container. However, there is a problem that the storage must be taken in and out through the side plate, which is very troublesome and laborious.
[0003]
Therefore, the present applicant arranges side plates on the four sides of the upper surface of the pallet, and a substantially comb-shaped engagement portion provided at the end portion of one side plate at the corner portion where the side plates are adjacent to each other at right angles and the end of the other side plate. An assembly container that detachably meshes with a substantially comb-shaped meshing portion provided in the section, and inserts a coupling rod into the coupling hole provided in the meshing portion of both side plates and the pallet, and is screwed with a nut. No. 5-16106.
[0004]
This can be easily disassembled by removing the connecting rod, and disassembling can reduce the transportation cost and storage cost.
[0005]
However, in this conventional example, the connecting rod is connected to the pallet in a state where the substantially comb-like engaging portions of the side plates adjacent to each other at right angles are engaged with each other, and the side plates are erected on the lower surface of each side plate. In the state where the four side plates are assembled into a quadrangle by meshing the meshing portions, the fitting configuration is employed in which the fitting projections are fitted into the fitting recesses formed on the upper surface of each side portion of the pallet. The side plate cannot be built on the four sides of the pallet unless the procedure of fitting the fitting protrusions of the side plates into the fitting recesses of the pallet is taken. In other words, after assembling the three side plates in a U-shape and building them on the three sides of the pallet, even if you try to attach the remaining one side plate, the meshing parts are engaged by fitting from the horizontal direction. However, the fitting projection and the fitting recess are fitted from the vertical direction, and it is impossible to perform both at the same time. Therefore, the three side plates are assembled in a U-shape and the pallet 3 is assembled. After it is built in the side, the remaining one side plate cannot be attached.
[0006]
In the above conventional example, after the three side plates are assembled in a U shape and built on the three sides of the pallet, not only the remaining one side plate can be attached, but also the three side plates Assembled in a U-shape and built on the three sides of the pallet, the remaining one side plate is connected to one end of the side plate assembled and built in a U-shape with a connecting rod, and the other end Even if the part is released by releasing the connection by the connecting rod, the end of the engagement part of the conventional example is not shaped to be able to rotate without being obstructed by the end face of the adjacent side plate, By rotating and opening one side plate, it is not possible to make it easy to put in and out the stored items. In addition, as described above, since the fitting protrusion and the fitting recess need to be fitted in the vertical direction, in this respect as well, the conventional example pivots one side plate to open and pivots to close. It cannot be connected with a connecting rod.
[0007]
For the above reasons, the conventional example needs to be in a state where a side plate is erected on the four sides of the pallet and assembled into a container shape when used, and for this reason, when putting in and out the stored items in a large assembly container, There is a problem in that the operator still has to put in and out of the stored items while being placed on the upper opening edge of the large assembly container or in the state where the worker has entered the container.
[0008]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and when used in a large assembly container with a simple configuration, one of the side plates can be freely opened to allow the stored items to be taken in and out of the assembly container. It is an object of the present invention to provide an assembly container that can be easily disassembled and made compact when not in use, and does not take up a large space when transported and stored.
[0009]

[0023]
As shown in FIG. 2, the side plate 3 is arranged in an upright position on each of the four sides of the top surface of the pallet 2, and the ends of the adjacent side plates 3 and the pallet 2 are detachably attached by the rotating shaft 5. Such an assembly container A is assembled and formed.
[0024]
Here, the rotating shaft 5 is as shown in FIG. 9, and a nut portion 5b is embedded and fixed to the lower end portion of a metal cylindrical body 5a, and the upper end portion of the cylindrical body 5a has a larger diameter than the cylindrical body 5a. The part 5c is fixed, and an operation protrusion 5d is provided on the upper surface of the flange part 5c.
[0025]
Thus, the above-mentioned side plate 3 is stood on the four sides of the upper surface portion of the pallet 2, and the bearing portion 4 provided at the end portion of the side plate 3 is fitted into the recess portion 7 provided at the end portion of the adjacent side plate 3. The bearings 4 of the adjacent side plates 3 are arranged in a plurality of stages shifted vertically so that the holes 13 of the upper and lower stages of the bearings 4 communicate with each other in the vertical direction and communicate with the upper end opening of the mounting hole 8 of the pallet 2. . In this state, the rotary shaft 5 is inserted from the hole 13 of the uppermost bearing portion 4, and the lower end portion of the rotary shaft 5 is inserted into the large-diameter hole portion 8 a of the mounting hole portion 8 of the pallet 2. The nut portion 5b provided at the lower end of the screw is screwed into the upper portion of the bolt 9 positioned in the large-diameter hole portion 8a (the screwing operation is performed by picking the operation protrusion 5d with a finger and rotating it). By assembling the flange portion 5c against the upper surface of the uppermost bearing portion 4, the bearing portions 4 of the adjacent side plates 3 are connected to each other by the rotating shaft 5 and also connected to the pallet 2, thereby assembling the assembly container A easily. To form. In this case, the adjacent side plate 3 can be easily connected and connected to the pallet 2 simply by inserting the rotating shaft 5 into the hole 13 of the upper and lower multi-stage bearing portion 4 and picking the operating projection 5d with a finger and rotating it. The assembly operability is excellent. In this assembled state, the operation portion 25 of the lock member 23 is pulled down, the locking projection 29a is removed from the locking groove 22, and the leg portion 24 is locked as shown in FIG. The groove 15 is fitted and locked. In this case, the contact portion 26 abuts against the upper end portion of the front shielding portion 18 so that the lock member 23 does not move downward in the locked state of FIG. The protrusion 29a is elastically locked to the locking step portion 20 so that the lock member 23 does not move upward in the locked state of FIG. In this locked state, the side plate 3 is connected to the pallet 2 not only at both end portions but also at the intermediate portion to prevent the intermediate portion from bulging outward or being recessed inward.
[0026]
Here, in order to put in and out the stored items in the assembly container A, the bearing portion 4 at one end of one of the four side plates 3 is removed from the rotating shaft 5, and the intermediate portion of the corresponding side plate 3 is removed. The lock member 23 locked to the pallet 2 is lifted upward to release the lock as shown in FIG. 12B, and the other end of the side plate 3 is rotated around the rotation shaft 5 in this state. As shown in FIG. 3, the side plate 3 is opened to open one side surface of the assembly container A, and the stored items are taken in and out from the opening 31.
[0027]
In order to rotate one side plate 3 around a rotation shaft 5 inserted through the bearing portion 4 at the other end, the tip end portion of the bearing portion 4 does not hit the flange surface of the recessed portion 7 which is the end surface of the adjacent side plate 3. It is necessary to do so. For this reason, in the present invention, the other bearing portion 4 of the side plate 3 is rotatable about the rotation shaft 5 in a state where the one bearing portion 4 of the side plate 3 is detached from the rotation shaft 5 to be free. Thus, an arc surface portion 6 is formed at the tip portion of the other bearing portion 4 to avoid the tip portion from hitting the end surface of another side plate 3 adjacent thereto. In the embodiment shown in the accompanying drawings, a bearing portion 4 projecting within a substantial width of the side plate 3 and a recess portion 7 where the bearing portion 4 does not project are formed in the vertical direction of the end surface of the side plate 3. If the arc surface portion 6 is provided to prevent the inner surface side of the tip portion 4 from hitting the flange surface of the recessed portion 7 of another adjacent side plate 3 when the bearing portion 4 rotates, the side plate 3 is closed. The gap between the end portions of the side plate 3 is prevented from being generated, and the side plate 3 can be rotated without hindrance. In this way, when the inner surface side of the front end portion of the bearing portion 4 is used as the arc surface portion 6, the front end portion of the bearing portion 4 may be a substantially semicircular arc surface portion 6 as shown in FIG. Thus, the tip of the bearing portion 4 may be an arc surface portion 6 having a substantially quarter circular shape in plan view.
[0028]
In order to remove one end of the side plate 3 from the rotating shaft 5 for rotating as a side lid, the rotating shaft 5 is rotated in the opposite direction to that at the time of attachment, and the rotating shaft 5 is extracted upward and rotated as a side lid. The side plate 3 to be caused to rotate is rotated around the rotation shaft 5 on the other end side of the side plate 3 so that the bearing portion 4 at one end of the side plate 3 is separated from the bearing portion 4 at one end of the adjacent side plate 3. Thereafter, the rotating shaft 5 removed earlier is inserted into the hole 13 of the bearing portion 4 at one end of the adjacent side plate 3, and the nut portion 5b at the lower end portion of the rotating shaft 5 is positioned in the large-diameter hole portion 8a. As shown in FIG. 3, only the bearing portion 4 of the adjacent side plate 3 is connected to the pallet 2 by the rotating shaft 5 as shown in FIG.
[0029]
As shown in FIG. 3, when a side plate 3 is rotated and used to be assembled again as an assembly container A after being put into and out of the assembly container A in a state where the side plate 3 is rotated, it is used to rotate as a side cover. The rotating shaft 5 which connects the edge part of the adjacent side plate 3 corresponding to the one end part side used as the free end of the side plate 3 to the pallet 2 is removed, and then the bearing part 4 and the side of the edge part of the side plate 3 are removed. The bearing 4 at the end of the side plate 3 used to rotate as a lid is shifted up and down, and the adjacent bearings 4 are connected to each other by the rotating shaft 5 in the same manner as in assembly, and the pallet 2 is connected. Further, the lock member 23 attached to the side plate 3 used as a side cover is connected to operate the lock member 23 as shown in FIG.
[0030]
With the contents stored in the assembly container A, the fork lift fork is inserted into the fork insertion part 1 provided on the pallet 2 of the assembly container A and moved in a lifted state, and placed on a truck, wagon, ship, etc. It is to be transported.
[0031]
Here, with the storage container stored in the assembly container A, the upper cover 32 is placed on the upper opening of the assembly container A as shown in FIG. 14, and the assembly container A and the upper cover 32 are bound by the band 33. It may be.
[0032]
On the other hand, when the assembly container A is not used, the four rotary shafts 5 are removed, the connection between the side plates 3 and the connection between the side plate 3 and the pallet 2 are released and disassembled. When the rotary shaft 5 is removed, the rotary shaft 5 can be easily unscrewed and removed simply by picking the operating projection 5d with a finger and rotating it, so that the adjacent side plates 3 can be easily connected. And can be disassembled by releasing the connection with the pallet 2 and has excellent decomposability. Further, when disassembled, since the upper end of the bolt 9 does not protrude above the upper surface of the pallet 2, the bolt 9 does not hinder the stacking of the pallets 9 together. Further, the lock member 23 attached to each side plate 3 is pulled upward to be in the state shown in FIG. By disassembling in this way, it can be transported in a compact manner, or by storing it, the space required for transport and storage can be reduced.
[0033]
For example, as shown in FIG. 15, the disassembled parts described above are stacked with a large number of pallets 2, and a plurality of upper lids 32 are stacked on the uppermost pallet 2, and are bound with a band as necessary. The lowermost pallet 2 is moved by lifting it using a forklift and is carried on a truck, a freight car, a ship, etc., or stored in a warehouse or the like.
[0034]
When disassembling and transporting or storing a large number of assembly containers A, most of the assembly containers A are disassembled with all side plates 3 removed, and the pallets 2 are stacked together as described above. The arbitrary assembly container A is formed by removing the other pair of opposing side plates 3 while leaving the pair of opposing side plates 3, and the pair of the upper surfaces of the pallet 2 leaving the pair of opposing side plates 3. A number of other side plates 3 are arranged between the side plates 3 as shown in FIG. Then, if necessary, the top lid 32 is put on and bound by the band 33 as shown in FIG. In the movement, the pallet 2 on which a large number of side plates 3 are placed is moved by lifting it using a forklift and is carried on a truck, a freight car, a ship, or stored in a warehouse or the like. In this case, the pallet 2 has a square shape in plan view, and the four side plates 3 have the same shape, so that the removed side plate 3 does not protrude from the pallet 2 and does not hinder the covering of the upper lid 32. It is.
[0035]
Further, as shown in FIG. 17, a large number of rotating shafts 5 are placed in an assembly container A that is not disassembled, covered with an upper lid 32, and bound by a band 33. For movement, a large number of side plates 3 are placed. The pallet 2 is moved by lifting it using a forklift, and is carried on a truck, a freight car, a ship, etc., or stored in a warehouse or the like.
[0036]

In addition, when putting in and out the stored items in the assembly container, the bearing portion at the other end of the side plate is rotated with one end of one side plate out of the four side plates having the same shape being free from the rotation shaft. By rotating and opening about the axis, the stored items can be taken in and out of the assembly container. Even if the assembly container is large, the stored items can be taken in and out of the assembly container. There is no need for the operator to put on and take out work on the edge of the upper opening of the assembly container, and the work can be taken out and taken in easily and quickly. The side plate is rotated and closed, and the bearing portion at one end is shifted up and down with respect to the bearing portion at one end of the adjacent side plate, and in this state, both bearing portions are attached to the pallet by the rotating shaft. Easily open side plate It is those that can be attached to close. In addition, the bearing portion and the bearing portion 4 in which the protruding length is substantially the same as the substantially width of the side plate and the arc surface portion is formed at the tip portion do not project within the width of the side plate at both ends of the side plate. Since the flat recess 7 is formed in the vertical direction, the side plate can be rotated without any trouble with a simple structure when the bearing portion at the other end of the side plate is rotated and opened around the rotation axis as described above. It can be opened and closed by moving.
