Description

【０００１】
【発明の属する技術分野】
本発明は、物品の運搬に供する四角形箱形であって、吊上げ又は持ち上げて積み上げが可能で、かつ折りたたんで重ね置きができる折りたたみ収納ボックスに関する。
【０００２】
【従来の技術】
従来から、本発明の折りたたみ収納ボックスと同類の折り畳みコンテナには、多数の提案がある（例えば、特開２００１−３２２６３８号公報、実公昭５６−４５９６号公報参照）。また、コンテナを積み上げるには、四隅の支柱の上端部に他のコンテナの下部枠を外嵌するもの（特開平１１−１４７５２２号公報参照）、あるいは上面開口部に他のコンテナ四隅の支柱を挿入し積み上げるもの等が知られている。
【０００３】
また、収容物が重くなれば、収納ボックスの移動には荷役装置を使用しなければならないが、そのために、荷役装置のフオークの厚みより大きい高さを有する脚部をコンテナ底面の四隅に設けたものが、特開平１１−４９１６２号公報に開示されている。一方、例えばトヨタのダイナクレーン付トラック（ユニック）等により２トン程度の重量物を吊上げることが普通に行われている。
【０００４】
【発明が解決しようとする課題】
前述した従来の積み上げ可能なコンテナにおいて、上面開口部に他のコンテナ四隅の支柱を挿入する方式は、コンテナ内に収容物が多いときには支柱が収容物に当るので、積み上げに手間取るという難点がある。また、コンテナ四隅の支柱上端部に他のコンテナの下部枠を外嵌するものは、外嵌に面倒が伴うという問題点がある。一方、従来の折りたたみ式の収納ボックスに対し、持ち上げおよび吊下げができるものに対する要望があった。本発明は、上述の事情に鑑み、折りたたみ、持ち上げおよび吊下げが可能な折りたたみ収納ボックスを提供することを、解決しようとする課題としている。
【０００５】
【課題を解決するための手段】
上述の課題解決のために、本発明は、長方形の四隅に立設した脚柱により水平に支持され、接地面と荷役装置のフオークが挿入可能な間隙を介し、前記脚柱の間に水平に固着した左右および前後の梁を設けた底板を備えた収納ボックスにおいて、前記左右および前後の梁の上面に沿って鋼製四角形格子体に形成した底板と、脚柱下端部に逆カップ状に固着した接地体と、前記接地体に挿入可能な上端部に孔部を設け前記左右側の脚柱の外側面に同高に固着した長方形板と、前記後方と左右の梁の上方に高低差をつけ前記脚柱の間にそれぞれ水平に固着した後面板取付桁、左側板取付桁および右側板取付桁と、上下に二分し、下部に上部を手前側に折曲げ自在に連結した正面板と、下部両側に前記左側取付桁と解除自在なロックバーを設け前記左側板取付桁上に連結した左側板と、下部両側に前記右側板取付桁と解除自在なロックバーを設け前記右側板取付桁上に連結した右側板と、前記後面板取付桁上に下端部を連結した後面板と、前記左右の側板の前後端部を前記接地体に挿入可能にするとともに吊環を設け、前記正面板、後面板、左側板、右側板を上部および中間部を解除自在に係止する鋼製四角形格子体に形成するとともに、内側に起倒自在にし、折りたたみ収納ボックスを構成した。
【０００６】
そして、底板を補強するために、前記脚柱間の左右、前後の梁の内側に補強梁を縦横に固着することが好ましい。
【０００７】
また、左右側板と正面板および後面板の結合を強化するために、両端部を長辺部と短辺部に下方へ直角に折曲げ、長辺部を前記左右側板上面の前後端部に回動自在に挿入して端末部に抜け止めを設け、短辺部を抜き上げ自在に前記正面板および後面板の上面に挿入し、長辺部を抜き上げて水平旋回し、短辺部を前記左右側板の上面中央部に間隔を介し設けた孔部に挿入するコーナブレースを設けるとよい。
【０００８】
【実施例】
以下、図面を参照して本発明の実施例を説明する。図１は、本発明に係る折りたたみ収納ボックス１の斜視図であり、２は底板、３は正面板、４は後面板、５は左側板、６は右側板である。底板２は長方形であり、図２のように、四隅に立設する脚柱７、８に、接地面との間に荷役装置のフオークを差込める間隙を介し前梁１３、後梁１４、左梁１５および右梁１６を水平に配設する。
【０００９】
脚柱７、８の下端部には、截頭四角錐の逆カップ状に形成した接地体９を水平に固着する。図２、図３を参照し説明すると、前後の脚柱８の間に左側板取付桁１８を左梁１５上に水平に設け、前後の脚柱７の間に右側板取付桁１９を右梁１６上方に水平に設ける。１７は、後梁１４の直上に脚柱７と８の間で水平に横設した後面板取付桁である。後面板取付桁１７を最低位置にし、左側板取付桁１８と右側板取付桁１９とは高低差をつけて設ける。高低差は、左右の側板５、６を折りたたむために、左右の側板５、６の厚さよりもわずかに大きくする。なお、本発明の折りたたみ収納ボックス１は、底板２上に、順次、正面板３、後面板４、左側板５、右側板６を折たたむものである。
【００１０】
７ａ、８ａは、下端に接地体９を水平に固着する脚支柱である。実施例は、脚支柱８ａが脚支柱７ａよりも背丈を大きくし、左側板取付桁１８よりも右側板取付桁１９を高位置にし、左側板５上に右側板６を折りたたむようにしている。右側板６上に左側板５を折りたたむ場合は、右側板取付桁１９よりも左側板取付桁１８を高位置にする。底板２は収容物の荷重を受けるので、補強のために前後の梁１３、１４と左右の梁１５、１６の内側に補強横梁２０、補強縦梁２１、２２を設ける（図２参照）。
【００１１】
図３において、正面板３を取付ける蝶番３ｃを前梁３の中央部と左右端部に固設し、後面板取付桁１７の内側面の中央部と左右端部に後面板４を取付ける蝶番３８を固設する。左側板取付桁１８と右側板取付桁１９の両端部内側に、それぞれ左側板５および右側板６を取付ける蝶番３１および３２を固設する。１２は鋼製四角形格子体であり、前後の梁１３、１４と左右の梁１５、１６の上面に沿って固着する。鋼製四角形格子体１２は、径５ｍｍの丸鋼で網目５ｃｍ角の格子に形成されている。
【００１２】
次に、図４を参照し左側板５を説明する。左側板５は、左前支柱５ａと左後支柱５ｂを脚支柱８ａの頂面と空隙２４を介し上方に併設し、両者間の上端部に上部枠金５ｃと下端に下部枠金５ｄを上下平行に固着し、左前支柱５a、左後支柱５ｂ、上部枠金５ｃ、下部枠金５ｄで囲まれる内側を四角形鋼製格子体５eにする。空隙２４は、左側板５を内方に倒伏する際に、脚支柱８ａの頂面と左側板５が干渉しないようにするためのものである。
【００１３】
２６はロックバーであり、平鋼の下端部を左側板取付桁１８の両端部にそれぞれ枢着２８し、上端部下面の符号省略の切込み部を左前後の支柱５a、５ｂの下部両縁に設けた突片２７に係止し、左側板５を左前後の支柱５a、５ｂおよび左側板取付桁１８に解除自在に固定するようになっている。すなわち、ロックバー２６上端部の切込み部を突片２７から外し、枢着２８周りに旋回すると、左側板５が左前後の支柱５ａ、５ｂとの係止が解除される。左側板取付桁１８の中央部に左右対向に固設した突片２９は、相互内側に旋回したロックバー２６、２６を受け止めるものである。
【００１４】
また、左梁１５の両端部に固設した突片２５は、折りたたみ収納ボックス１を折りたたんで重ね置きしたときに、下部の折りたたみ収納ボックス１のロックバー２６の上端部を係止し、重ね置き状態を固定するように設けられている（図１４参照）。左側板５は、両下端部が左側板取付桁１８上に蝶番３１により内方に倒伏自在に連結されている。３３は、吊上げ装置付トラック（ユニック）等で吊り上げるための吊環であり、左前支柱５aと左後支柱５ｂの上端部に設けている。３５は、後述するロッド形締め具３４の係止受け片であり、左前支柱５aの前端面上部に突設している。
【００１５】
右側板６は、図１に示すように、右前支柱６aと右後支柱６ｂを前後の脚支柱７aの頂面と空隙２４を介し上方に併設し、この支柱６a、６ｂに固設する上下に平行な上部枠金６ｃ、下部枠金６ｄと支柱６a、６ｂの内側を鋼製四角形格子６eに形成する。右前支柱６aの上部前端面にロッド形締め具３４の係止受け片３５を突設し、右前支柱６aと右後支柱６ｂの上端部に吊環３３を設ける、すなわち、左側板５と右側板６との４個の吊環３３によって、折りたたみ収納ボックス１が四点吊りされるようになっている。
【００１６】
右側板取付桁１９の中央部両側の突片２９、右梁１６の前後両端部に固設した突片２５、下部両側に設けたロックバー３６は、左側板５で説明したのと同様の構成である。ロックバー３６の下端部は、右側板取付桁１９に枢着２８され、ロックバー３６の上端部は右前後の支柱６a、６ｂに設けた突片３０、３０に係止するようになっている。右梁１６の前後両端部の突片２５は、折りたたみ収納ボックス１を折りたたんで重ね積みしたとき、下方の折りたたみ収納ボックス１のロックバー３６の上端部が係止され、重ね積みを固定するように設けられている。右側板６は、下部枠金６ｄの左右が蝶番３２で右側板取付桁１９に連結され、内方へ倒伏自在になっている。
【００１７】
次に、図１を参照し正面板３を説明する。正面板３は上下に二分し、鋼製下部四角形格子体（以下、下部四角形格子体という）３ｂの上方に鋼製上部四角形格子体（以下、上部四角形格子体という）３ａを上下に揃え蝶番２３で中央部と左右両端部を連結し、上部四角形格子体３aが手前側に折れるようになっている。上部四角形格子体３aの上部両端部には、トラック荷箱等で公知のロッド形締め具３４を固設し、下部四角形格子体３ｂの上部両端部に上下旋回自在に短ロックバー３７を設け、正面板３を左側板５および右側板６の前端面に係止するようになっている。正面板３は、下部四角形格子体３ｂの下端部が、前梁１３の中央部と左右両端部に固設した蝶番３ｃで前梁１３に連結され、底板２上に倒伏自在になっている。
【００１８】
次に、図５を参照して後面板４を説明する。後面板４は、上部枠金４a、左枠金４ｂ、右枠金４ｃおよび下部枠金４ｄで四角形に形成され、中央部を中央縦桁４eで仕切り、鋼製四角形格子体に形成している。後面板４の横幅は、立起した左側板５と右側板６との間の間隔であり、高さは後面板取付桁１７の内側面に固設した蝶番３６に下部枠金４ｄを連結したとき、上面が左右の側板５、６の上面と一致する高さである。また、左枠金４ｂと右枠金４ｃの上部に短ロックバー３７を上下旋回自在に設け、後面板４が左右の側板５、６に解除自在に結合されている。そして、後面板４は、既に底板２上に倒伏している正面板３上に蝶番３８を介し倒伏するように設けられている。
【００１９】
図６は本発明の折りたたみ収納ボックス１の平面図であり、正面板３および後面板４と左右の側板５、６とのコーナ部に、それぞれコーナブレース３９を設けている。コーナブレース３９は、図８に示すように、両端部を下方に直角に折り曲げた長辺部４０と短辺部４１にし、前記左右の側板５、６上面の前後端部に設けた孔部a（図７参照）に回動自在に挿入する長辺部４０の下端に抜け止めナット４２を螺着し、短辺部４１を抜き上げ自在に前記正面板３および後面板４の上面に挿入し、長辺部４０を抜き上げて水平旋回し、短辺部４１を前記左右の側板５、６（図７は左側板５について示している）の上面中央部に間隔を介し設けた孔部ｂ、ｂに挿入するようになっている。
【００２０】
図９は、図１の左側上部の係止状態を示す斜視図であり、正面板３の左上コーナ部にロッド形締め具３４を設け、左側板５の前側支柱５aの前端面上部に突設した係止受け片３５のU形溝部４６にＬ形棒４３が嵌り込み、正面板３と左側板５とが結合されている。４４は、正面板３の左上コーナ部に固設された軸受部であり、Ｌ形棒４３の上部折曲げ部が回動自在に挿通し、挿通した折曲げ部の右端末が、つば頭４５になってＬ形棒４３が軸受部４４に抜け止めされている。
【００２１】
Ｌ形棒４３は、一点鎖線で示すように上方に旋回し右方にスライドすると、図１０のように、係止受け片３５から外れるようになっている。４７はＬ形棒保持枠であり、Ｕ形横断面の溝部にＬ形棒４３が嵌り込むように、正面板３の上部左縁部に固着されている。ロッド形締め具３４は正面板３の右上コーナ部にも設けられ（図１参照）、右側板６と正面板３とを解除自在に結合している。
【００２２】
図１１は、本発明の折りたたみ収納ボックス１の折りたたみ状態を示す正面図であり、ロッド形締め具３４、短ロックバー３７の係止を解除した正面板３を、底板２上に蝶番３ｃを介し倒伏し、その上に短ロックバー３７の係止を解除した後面板４が蝶番３８を介し倒伏している。後面板４の上にロックバー２６の係止を解除した左側板５が蝶番３１を介し倒伏し、さらに左側板５の上にロックバー３６の係止を解除した右側板６が、蝶番３２を介し倒伏している。
【００２３】
そして、上述のように折りたたまれた収納ボックス１は、脚柱７、８外側面の長方形板１０上端部の孔部１１にクレ−ンの吊ロープ先端のフックを引っ掛け、一体に吊上げ移動することができる。また、長方形板１０の上端部に他の折りたたまれた収納ボックスの接地体９を載せることによって重ね置きされる。重ね置きされた収納ボックス１は、右側が右側板６のロックバー３６の上端部を上方の収納ボックス１の右梁１６に設けられた突片２５に係止し、左側が左側板５のロックバー２６の上端部を右側と同様に左梁１５の突片２５に係止し、重ね置きを固定する。
【００２４】
図１２は、折りたたんだ状態から箱形に復元する中間状態の正面図である。すなわち、前述のように折りたたんだ収納ボックス１は、先ず右側板６を矢印のように引き起こし、次いで左側板５を同じく引き起こす。次いで後面板４を蝶番３８を介し引き起こし、左右上端部の短ロックバー３７を左側板５の左後支柱５ｂと右側板６の右後支柱６ｂに設けた符号省略の突片に係止する。
【００２５】
次いで、正面板３を引き起こし、左右両端部のロッド形締め具３４のＬ形棒４３を左右の側板５、６の前端面上部の係止受け片３５に係止し、さらに左右中間部の短ロックバー３７を左前支柱５ａと右前支柱６aの中間部前端面に設けた符号省略の突片に係止する。そして、左側板５のロックバー２６の上端部を左前後の支柱５a、５ｂの突片２７に係止し、同じく右側板６のロックバー３６の上端部を右前後の支柱６a、６ｂ中間部の突片３０に係止する。また、コーナバー３９を左右の側板５、６から長辺部４０を引上げて水平旋回し、短辺部４１を正面板３と後面板４のそれぞれ上面の孔部に挿入する。以上のようにすることによって、折りたたみ収納ボックス１は箱型の使用状態になる。
【００２６】
図１３は、本発明の折りたたみ収納ボックス１の積み上げ状態の斜視図である。
すなわち、最下段の収納ボックス１が前後、左右の脚柱７、８で水平に支持され、二段目の収納ボックス１の接地体９が最下段の収納ボックス１における前後の支柱５a、５ｂ、６a、６ｂの上端部に外嵌し、積上げられている。同様に、二段目の収納ボックス１に三段目、三段目の収納ボックス１に四段目の収納ボックス１が積み上げられている。積み上げには、底板２の下にフオークリフトのフオークを差込んで持ち上げるか、四隅上部の吊環３３をクレーンで吊上げて行うことができる。また、左右のロッド形締め具３４の係止を解除し、上部鋼製四角形格子体３ａを蝶番２３によって開くと、収納ボックス１内の収容物を取出すことができる。
【００２７】
図１４は、折りたたんだ収納ボックス１を重ね置きした状態の左側面図である。すなわち、折りたたまれた収納ボックス１の左右前後の脚柱７、８に同高に固着された長方形板１０の上部に、他の折りたたまれた収納ボックス１の接地体９を外嵌し、順次に重ね置きをした状態である。既に説明したように、下段の収納ボックス１における左側板５の左右に設けられたロックバー２６の上端部が、上段の収納ボックス１の左梁１５における左右の突片２５に係止され、積み置き状態が固定されている。同様にして、右側面もロックバー３６で上下の収納ボックス１が固定されている。重ね置きには、長方形板１０上部の孔部１１にクレーンのロープ先端のフックを引っ掛けて吊上げるか、フオ−クリフトで持ち上げる。
【００２８】
【発明の効果】
請求項１の発明によれば、本発明の折りたたみ収納ボックスは、左右側板と正面板および後面板の上部と中間部が解除自在に係止され、これらが四角形底板の四辺部に高低差をつけ内側に起倒自在に連結されているので、係止を解除するという簡単な操作によって、これらを底板上に順次に折りたたむことができる。また、底板、左右の側板、正面板および後面板を鋼製四角形格子体にしたので、収納ボックスを軽量化することができる。
【００２９】
また、底板の四隅に立設した脚柱の外側面に長方形板を同高に固着するとともに、下端部に前記長方形板の上端部が挿入可能な接地体をカップ状に固着したので、折りたたんだ収納ボックス四隅の接地体を他の折りたたんだ収納ボックス四隅の長方形板の上端部に容易に外嵌することができるので、折りたたんだ収納ボックスを簡単に重ね置きすることができる。したがって、収納ボックスを折りたたんで保管容積の少ないものにすることができる。
【００３０】
また、収納ボックスの四隅上端部に吊環を設けたので、吊環をクレーンで吊り上げることによって、物品を収容した状態でも収納ボックスを移動することができる。また、底板と接地面との間に荷役装置のフオークを差込むことができる間隙を設けたので、収納ボックスの持ち上げに荷役装置を利用することができる。そして、上下に二分した正面板の上部四角形格子体を下部四角格子体に対し固定および手前側に折曲げ可能に連結したので、上部四角形格子体を開き収容物を取出すことができる。
【００３１】
請求項２の発明によれば、底板の補強が可能になり、重量物を収容できる収納ボックスを得ることができる。請求項３の発明によれば、正面板、左右の側板および後面板の上部が相互に形成するコーナ部をコーナブレースによって確実に結合し、収納ボックスの結合強度を向上させることができる。しかも、コーナブレースが抜け止めされているので、散逸することがない。
