Description

【０００１】
【発明の属する技術分野】
本発明は、冷凍食品、生鮮食品等を収容してトラックやパネルバン等で運搬するに好適な折畳収容箱に係り、詳しくは、良好な折畳み及び組立の操作性と強度とを有する折畳収容箱に関するものである。
【０００２】
【従来の技術】
出荷された生鮮食品や冷凍食品を専門店やコンビニ等に卸す手段として、分解や折畳みが自在な保冷箱を用いることが多い。つまり、出荷するときには組み立てて商品を収容して運送し、商品を卸して空になった保冷箱は分解や折畳んでコンパクト化し、トラック荷台での作業の邪魔にならないようにするとか、作業用スペースを広げられる等の利点が得られる便利なものである。このような収納箱としては、特許文献１や特許文献２に示されたものが知られている。
【０００３】
特許文献１に開示された断熱収納箱は、底面板、前面板、裏面板、左右の側面板、及び上面板の６つの面板が互いに着脱自在に構成されているので、断熱のために比較的厚い部材を面板として用いながら、不使用時には折畳んでコンパクト化することができる利点がある。また、特許文献２に開示された断熱箱は、蓋と底板とを夫々前板と後板にヒンジ連結するとともに、左右の側板を前後に腰折れ自在とすることにより、不使用時には、アコーディオンのようにコンパクトに折畳めるようになっている。

【発明が解決しようとする課題】
しかしながら、特許文献１のものは組立て折畳みの際に厚みのある各面板を回動させる必要があり、組立てを一人で行うのが困難であった。
【０００６】
また、特許文献２のものは各板部材がヒンジで相互連結されているので、部品の紛失するおそれもなく組立てや折畳みが行えるのは良いが、構造上、前後左右の各側板の隣合うものどうしは角部どうしの接触状態となるので、隣合う側板どうしの相対角度が定まり難く、フラフラした状態になっている。そのため、蓋板と底板との内面側に、左右側板の折曲りを規制する防止部材を設けるという構造の複雑化を招いており、それでも、箱に組立てた状態での保形性には乏しく、ちょっとした外圧やショックで左右の側板が内側に折曲ったり、歪んだりし易いという強度面での問題があった。
【０００７】
本発明の目的は、これらの問題点を改善し、折畳み時の部品紛失のおそれが無く、一人でも簡単に分解並びに組立てが行え、しかも、箱の状態での強度が高く、保形性に優れる折畳収容箱を提供する点にある。
【０００８】
【課題を解決するための手段】
前述の課題を解決するための本発明の請求項１に記載の折畳収容箱は、底板と前後側板と左右側板と蓋板とを有した六面体状の折畳収容箱において、前後左右側板のうちのいずれか一つ乃至三つの側板を、底板の端部に一体化された下部側板と、この下部側板の上端部にヒンジを介して横軸心回りで箱内方に向けて折畳自在に連結された上部側板とから成る腰折れ側板に構成し、前後左右側板のうちの腰折れ側板以外の非腰折れ側板のうちの一つを、底板の端部にヒンジを介して箱内方に向けて折畳自在に連結し、残りの非腰折れ側板がある場合には、一つの非腰折れ側板に隣合うものから順次、箱外方に向けて縦軸心回りで折畳自在にヒンジを介して連結するとともに、蓋板を、腰折れ側板の一つの上端部に横軸心回りで箱外方に折畳自在に連結してあることを特徴とする。
【０００９】
この請求項１の構成によれば、底板と前後側板と左右側板と蓋板との６つの板が全てヒンジ連結されているので、箱としての作用状態でも、折畳まれた収納状態でも板どうしが互いにばらばらにはならず、従って、いずれかの板が無くなってしまったとか、部品が足りないといった不都合は生じないようになる。そして、非腰折れ側板が２枚以上ある場合には、底板にヒンジ連結されたもの以外は、箱外方に向けて縦軸心回りで折畳自在であるから、非腰折れ側板から、例えば、単独で開き揺動できる前側板（図４や図７（ａ）参照）から、開閉自在な蓋板とは別に収容物の出し入れを行うことが可能になる。
【００１０】
また、底板は、その周囲４辺のうち、少なくとも１辺から多くは３辺が、腰折れ側板の下部側板と一体化されて、単なる平板状ではなくチャンネル型断面に補強されるから、底板の強度・剛性自体が向上するとともに、箱として組立てた場合には、その補強された辺においては、隣合うヒンジ連結箇所が縦又は横方向で位置ずれした状態になり（図１０の軸心Ｐ１とＰ４参照）、ヒンジ連結箇所での歪みが増幅され難い点で、保形強度的に有利になる。加えて、どの板もヒンジ連結による揺動移動によって組立て及び折畳みが行えるので、一人の作業者のみで箱の組立て操作及び折畳み操作を簡単に行うことが可能になる。
【００１１】
その結果、底板の少なくとも一辺から多くは三辺を、腰折れ側板の下部側板と一体化したことで、箱としての強度・剛性が向上し、収容物をより安定的に輸送できるとともに、全ヒンジ連結構造により、部品の紛失おそれがなく確実に、かつ、一人の作業者で簡単に組立て及びコンパクトに折畳み収納できるようになり、操作性及び信頼性に優れる折畳収容箱を提供することができる。
【００１２】
請求項２に記載の折畳収容箱は、請求項１の構成において、箱外方に折畳自在に互いにヒンジ連結される一対の板は、それらのヒンジ連結側の端面どうしが、箱として組立てられた組立て作用状態において面接触する状態に構成されていることを特徴とするものである。
【００１３】
請求項２の構成によれば、例えば、ヒンジ連結されて互いに隣合う板どうしが、４５度に傾斜された傾斜端面どうしがぴったりと面接触する（図３の１ｔと４ｔ参照）といった具合に、組立て作用状態からそれ以上箱内方には揺動できないようにするストッパー機能が広い荷重面積によって行われるので、確実に揺動規制できるとともに、節度感のある操作タッチが得られるようにもなる。
【００１４】
その結果、箱外方に折畳み自在にヒンジ連結される板どうしでは、確実な過揺動規制が行えて歪みを軽減できるので、その分箱としての強度・剛性を実質的に増すことができるとともに、節度のある好ましい揺動操作感覚も得られる畳収容箱を提供することができる。また、面接触とすることで箱内部の密閉性、断熱性も保たれる。
【００１５】
請求項３に記載の折畳収容箱は、請求項２の構成において、左又は右側板と後側板とを腰折れ側板に設定し、左又は右側板のうちの非腰折れ側板を、一つの非腰折れ側板に設定するとともに、この一つの非腰折れ側板と前側板及び後側板と蓋板とを、箱外方に折畳自在に互いにヒンジ連結してあることを特徴とするものである。
【００１６】
請求項３の構成によれば、底板の４辺のうちの互いに隣合う２辺が腰折れ側板の下部側板と一体化され、かつ、蓋板と前側板とが収納物の出し入れ用として開閉自在になり、かつ、前側板は縦軸新回りで横開きできるので、程よく強度・剛性を向上しながら、操作し易い開閉扉が上と前の２箇所に存在して、より扱いやすく便利な折畳収容箱にできる。
【００１７】
請求項４に記載の折畳収容箱は、請求項１〜３の構成において、底板、蓋板、前後左右側板のうちの隣合うものどうしに跨って作用する面ファスナを設けてあることを特徴とするものである。
【００１８】
請求項４の構成によれば、箱に組立てた作用状態を、面ファスナによる引掛け係合機能によって維持させるものであり、面ファスナの至極簡単な着脱操作としながら、箱状態を比較的強固に維持できて保形性に優れる折畳収容箱とすることができる。
【００１９】
【発明の実施の形態】
以下、本発明の実施の形態の一例を図面に基づいて説明する。
まず、図１〜図３は組立てられた作用状態の三面図、図４は組立て途中の斜視図、図５は各板の構成及び隣合う板との関係を示す分解斜視図で、図６は折畳まれた状態を示してある。また、図７〜図１３に示す各図は、折畳収容箱の組立て及び折畳み状況を分り易くするために、全てのヒンジ及び面ファスナを省略して描いてある。
【００２０】
本発明による折畳収容箱Ａは、図１〜図３に示すように、蓋板１、底板２、前側板３、後側板４、左側板５、及び右側板６とから成る６面体であって、冷凍食品、冷蔵食品等の保温が必要な物品を収容して運搬するに好適な断熱保冷箱に構成されている。この折畳収容箱Ａは、冷凍食品等を収容する使用時は、図１〜図３に示すように、組立てられた箱になり、不使用時には、図６、図１３に示すように、折畳んでコンパクト化することができる。
【００２１】
尚、以下においては、「内折れ」とは箱の状態において内部に向かって折れるの意であり、「外折れ」とは箱の状態において外部に向かって折れるの意である。また、「ヒンジ」は布やビニール等のシート状体で構成されており、隣合う板どうしを揺動自在に連結するものである。
【００２２】
後側板４は、図４、図５、図８等に示すように、底板２に一体化された下部板４ａと、この下部後板４ａに対して第１横軸心Ｐ１で内折れ揺動自在に第１ヒンジ７を介して連結され、かつ、上端に蓋板１が第２横軸心Ｐ２で外折れ揺動自在に第２ヒンジ８を介して連結された上部後板４ｂとで構成されている。下部後板４ａ及び上部後板４ｂ夫々は、それらの左右に連結用のシート１３，１４を有している。つまり、この後板４は腰折れ側板の一部を構成する。
【００２３】
右側板６は、図３〜図５等に示すように、底板２に一体化された下部右側板６ａと、この下部右側板６ａに対して第３横軸心Ｐ３で内折れ揺動自在に第３ヒンジ９を介して連結された上部右側板６ｂとで構成されている。下部右側板６ａ及び上部右側板６ｂ夫々の前端には、連結用のシート１５，１６を有している。つまり、この右側板６は腰折れ側板の一部を構成する。
【００２４】
左側板５は、図４、図５、図９等に示すように、底板２に第４横軸心Ｐ４で内折れ揺動自在に第４ヒンジ１０を介して連結されるとともに、左側板５の前端には、第１縦軸心Ｑ１で外折れ揺動自在に第５ヒンジ１１を介して前側板３が連結されている。
【００２５】
前側板３は、図４、図５、図７等に示すように、左側板５に第５ヒンジ１１を介して連結された基板部３ａと、この基板部３ａに第２縦軸心Ｑ２で内折れ揺動自在に第６ヒンジ１２を介して連結された先板部３ｂとで構成されている。基板部３ａの右端面に、先板部３ｂを連結するためのシート１９を装備してある。こ基板部３ａの付け根側端面３ｔと、左側板５の前端面５ｔとは、箱の状態に組立てたときに、丁度互いに同じ面積でもって面接触するように、４５度の傾斜角度でカットされた形状としてある。
【００２６】
底板２は、図４、図５、図８等に示すように、下部板４ａと、下部右側板６ａと、これら両者を一体に有した底板部２Ａとから成る立体的な形状に形成されている。この底板２は、平板状の底板部２Ａを、互いに一体化された下部板４ａと下部右側板６ａとで補強されており、従来の１枚板状の底板に比べて強度・剛性に優れている。
【００２７】
後側板４に枢支された状態の蓋板１は、図４、図５、図８等に示すように、その左右に連結用のシート１７を、かつ、その前端には連結用のシート１８を有している。蓋板１の前端面１ｔと、上部後板４ｂの上端面４ｔとは、箱の状態に組立てたときに、丁度互いに同じ面積でもって面接触するように、４５度の傾斜角度でカットされた形状としてある。つまり、これら板１，４の厚み方向で箱外側部に設けて、蓋板１が一つの非腰折れ側板４の外面に沿う状態に折畳まれた収納姿勢と、その収納姿勢から２７０度閉じ揺動させた組立て作用姿勢との双方において、これら両板１，４どうしが面接触する状態に構成してある。
【００２８】
つまり、請求項１の記載に則ってこの折畳保冷箱Ａの構成を表現すれば、後側板４と右側板６と（「前後左右側板のうちのいずれか一つ乃至三つの側板」の一例）を、底板２の端部に一体化された下部側板４ａ，６ａと、この下部側板４ａ，６ａの上端部にヒンジ７，９を介して横軸心Ｐ１，Ｐ３回りで箱内方に向けて折畳自在に連結された上部側板４ｂ，６ｂとから成る腰折れ側板に構成し、左側板５（「前後左右側板のうちの腰折れ側板以外の非腰折れ側板のうちの一つ」の一例）を、底板２の端部にヒンジ１０を介して箱内方に向けて折畳自在に連結してある。そして、前側板３（「残りの非腰折れ側板」の一例）を左側板５（「一つの非腰折れ側板」の一例）に、箱外方に向けて縦軸心Ｑ１回りで折畳自在にヒンジ１１を介して連結するとともに、蓋板１を、後側板４（「腰折れ側板の一つ」の一例）の上端部に横軸心Ｐ１回りで箱外方に折畳自在に連結してある。
【００２９】
各板１〜６は、図１４に示すように、一対の厚さの薄いポリプロピレン中空樹脂板２１，２１の間に、断熱材の一例であるポリエチレン独立発泡体２０を挟んだサンドイッチ構造の母材を、合成樹脂の発泡シート２２とＰＶＣターポリン等の合成樹脂シート２３等で覆う断熱板に構成されている。尚、各シート１３〜１９と、これらの連結対象となる箇所とには、係合側ファスナｋと被係合側ファスナｈとで成る面ファスナＦが装備されており、その長さは種々に設定されている。次に、折畳収容箱Ａの折畳手順について説明する。
【００３０】
まず、図１〜図３に示す箱としての使用状態から、左右のシート１７及びシート１８の面ファスナＦを引き剥がし、それから第２ヒンジ８を用いて蓋板１を第２横軸心Ｐ２回りに外折れ揺動（開き揺動）し、図８に示すように、後側板４の外面に沿う状態に折畳む。
【００３１】
次に、シート１９の面ファスナＦを引き剥がしてから、基板部３ａを左側板５に対して第１縦軸心Ｑ１周りに外折れ揺動しながら、先板部３ｂを基板部３ａに対して第２縦軸心Ｑ２周りに内折れ揺動させ、図９に示すように、基板部３ａは左側板５の外面に、かつ、先板部３ｂは基板部３ａの内面に夫々ぴったりと沿う状態に前側板３を折畳む。
【００３２】
それから、左側のシート１３，１４の面ファスナＦを引き剥がしてから、二つ折り状態の前側板３を伴った左側板５を、第４ヒンジ１０を用いて第４横軸心Ｐ４周りに内折れ揺動させて、図１０に示すように、底板部２Ａの上面に沿う状態に折畳むのである。このとき、最も上に位置する先板部３ｂの外面（上面）の高さ位置は、第３横軸心Ｐ３の高さと同じか若干低い位置となるように設定されている。
【００３３】
次に、右側のシート１３，１４の面ファスナＦを引き剥がしてから、上部右側板６ｂを第３ヒンジ９を用いて第３横軸心Ｐ３周りに内折れ揺動させて、図１１に示すように、先板部３ｂの外面（上面）に沿う状態に折畳む。このとき、上部右側板６ｂの外面の高さは、第１横軸心Ｐ１の高さと同じか若干低い位置となるように設定されている。
【００３４】
最後に、蓋板１を背負った状態の上部後板４ｂを、第１ヒンジ７を用いて第１横軸心Ｐ１回りに内折れ揺動させて、図６、図１２、図１３に示すように、上部右側板６ｂの外面に上部後板４ｂが丁度沿う状態に設定されている。このように、全ての板１〜６が互いに繋がったままで、しかも、後側板４と右側板６との腰折れ軸心の高さ位置を、前述の如く適宜な値に設定することにより、無駄な空間や隙間を無くしてコンパクトに折畳むことができている。
【００３５】
この折畳収容箱Ａでは、収容物の取出し及び収納が蓋板１の開閉によって行えるだけでなく、図７（ａ）に示すように、前側板３を第１縦軸芯Ｑ１回りに揺動して、箱としての前面から行うこともできる。従って、残り少なくなった底板部２Ａ近くの収容物は、前側板３の開閉によって箱の前方側から簡単で便利に行える利点がある。また、各面ファスナＦの係合側ファスナｋは、各板（１と６等）の端部に固着されたシート（１８等）に固着されており、係合側ファスナｋを被係合側ファスナｈに係合させての面ファスナＦの装着時には、隣合う板どうし（１と６等）が重ね合わされた部分の間隙が、シート（１８等）で覆われる状態となるので、保温性（保冷性）を向上し得る利点がある。
【００３６】
なお、本発明に係る折畳収容箱Ａは、前述の実施形態例に限定されるものではなく、以下のような形態のものも含むものである。
（１）折畳収容箱Ａは、図１５に示すように、後側板４及び左右側板５，６（「前後左右側板のうちのいずれか三つの側板」の一例）を、底板２の端部に一体化された下部側板４ａ〜６ａと、この下部側板４ａ〜６ａの上端部にヒンジを介して横軸心Ｐ１，Ｐ５，Ｐ３回りで箱内方に向けて折畳自在に連結された上部側板４ｂ〜６ｂとから成る腰折れ側板に構成し、前側板３（「前後左右側板のうちの腰折れ側板以外の非腰折れ側板のうちの一つ」の一例）を、底板２の端部にヒンジを介して箱内方に向けて折畳自在に連結し、蓋板１を、後側板４（「腰折れ側板の一つ」の一例）の上端部に横軸心Ｐ２回りで箱外方に折畳自在に連結した構造の折畳収容箱Ａでも良い。
【００３７】
この場合は、請求項１に言う「残りの非腰折れ側板］が存在しない場合に相当している。また、図１５に示すように、蓋板１を、後側板４に４５度のカット面で面接触する傾斜端面１ｔを有した状態でヒンジ連結された基板部１ａと、これに外折れ自在にヒンジ連結された先板部１ｂとで構成しても良い。
【００３８】
（２）折畳収容箱Ａは、図１６に示すように、後側板４（「前後左右側板のうちのいずれか一つの側板」の一例）を、底板２の端部に一体化された下部側板４ａと、この下部側板４ａの上端部にヒンジを介して横軸心Ｐ１回りで箱内方に向けて折畳自在に連結された上部側板４ｂとから成る腰折れ側板に構成し、左側板５（「左前後左右側板のうちの腰折れ側板以外の非腰折れ側板のうちの一つ」の一例）を、底板２の端部にヒンジを介して箱内方に向けて折畳自在に連結し、前側板３は左側板５に、かつ、右側板６は前側板３に、夫々箱外方に向けて縦軸心Ｑ１，Ｑ３回りで折畳自在にヒンジを介して連結するとともに、蓋板１を、後側板４（「腰折れ側板の一つ」の一例）の上端部に横軸心Ｐ２回りで箱外方に折畳自在に連結した構造の折畳収容箱Ａでも良い。この場合は、請求項１に言う「残りの非腰折れ側板」は、前側板３と右側板６とに相当する。
【００３９】
（３）後側板４の左右に設ける連結シートは、図４に示すように、面ファスナが上部後板４ｂと上部右側板６ｂとに跨るだけの長さを有した上下に長い単一の連結シート１３を設ける構造でも、図５に示すように、上部連結シート１３と下部連結シート１４とに分割して一対設けた構造のいずれでも良い。また、折畳収容箱Ａとしては、前述した断熱保冷（保温）箱だけでなく、衣服や靴等箱の収容箱として、或いは、ティッシュケースやトイレットペーパー等、断熱を要しない収容箱にも適用自在である。
【００４０】
さらに、約２７０度内折れ揺動させて面接触する端面どうし（１ｔと４ｔ等）は、４５度どうしが最も接触面積が多く取れて好都合であるが、その他、４０度と５０度や３０度と６０度といった組合せでも可能であり、この構成を請求項２においては「箱として組立てられた組立て作用状態において面接触する状態に構成されている」と表現してある。
【００４１】
【発明の効果】
以上説明したように、本発明の請求項１は、底板と前後側板と左右側板と蓋板とを有した六面体状の折畳収容箱において、前後左右側板のうちのいずれか一つ乃至三つの側板を、底板の端部に一体化された下部側板と、この下部側板の上端部にヒンジを介して横軸心回りで箱内方に向けて折畳自在に連結された上部側板とから成る腰折れ側板に構成し、前後左右側板のうちの腰折れ側板以外の非腰折れ側板のうちの一つを、底板の端部にヒンジを介して箱内方に向けて折畳自在に連結し、残りの非腰折れ側板がある場合には、一つの非腰折れ側板に隣合うものから順次、箱外方に向けて縦軸心回りで折畳自在にヒンジを介して連結するとともに、蓋板を、腰折れ側板の一つの上端部に横軸心回りで箱外方に折畳自在に連結してあることを特徴とするものである。
【００４２】
その結果、底板の少なくとも一辺から多くは三辺を、腰折れ側板の下部側板と一体化したことで、箱としての強度・剛性が向上し、収容物をより安定的に輸送できるとともに、全ヒンジ連結構造により、部品の紛失のおそれがなく確実に、かつ、一人の作業者で簡単に組立て及びコンパクトに折畳み収納できるようになり、操作性及び信頼性に優れる折畳収容箱を提供することができる。
【００４３】
請求項２の構成によれば、箱外方に折畳み自在にヒンジ連結される板どうしでは、確実な過揺動規制が行えて歪みを軽減できるので、その分箱としての強度・剛性を実質的に増すことができるとともに、断熱性、密閉性に優れ、節度のある好ましい揺動操作感覚も得られる畳収容箱を提供することができる。
【００４４】
請求項３の構成によれば、底板の４辺のうちの互いに隣合う２辺が腰折れ側板の下部側板と一体化され、かつ、蓋板と前側板とが収納物の出し入れ用として開閉自在になり、かつ、前側板は縦軸新回りで横開きできるので、程よく強度・剛性を向上しながら、操作し易い開閉扉が上と前の２箇所に存在して、より扱いやすく便利な折畳収容箱にできる。
【００４５】
請求項４の構成によれば、箱に組立てた作用状態を、面ファスナによる引掛け係合機能によって維持させるものであり、面ファスナの至極簡単な着脱操作としながら、箱状態を比較的強固に維持できて保形性に優れる折畳収容箱とすることができる。

[Problems to be solved by the invention]
However, in the case of Patent Literature 1, it is necessary to rotate each thick face plate at the time of assembling and folding, and it is difficult to assemble alone.
[0006]
Further, in the case of Patent Document 2, since the respective plate members are interconnected by hinges, it is good that assembly and folding can be performed without fear of losing parts. Since the corners come into contact with each other, it is difficult to determine the relative angle between the adjacent side plates, and it is in a fluttering state. For this reason, the inner surface of the lid plate and the bottom plate has a complicated structure in which a preventive member for restricting bending of the left and right side plates is provided, and yet, the shape retention in the state of being assembled in a box is poor. There was a problem in strength that the left and right side plates were easily bent inward or distorted by a slight external pressure or shock.
[0007]
An object of the present invention is to solve these problems, eliminate the risk of losing parts when folded, allow easy disassembly and assembly by one person, and have high strength in a box state and excellent shape retention. The point is to provide a folding storage box.
[0008]
[Means for Solving the Problems]
A foldable storage box according to claim 1 of the present invention for solving the above-mentioned problem is a hexahedral foldable storage box having a bottom plate, front and rear side plates, left and right side plates, and a cover plate. Any one to three of the side plates can be folded toward the inside of the box around the horizontal axis via a hinge at the upper end of the lower side plate integrated with the end of the bottom plate and the upper end of the lower side plate. The upper side plate is connected to the waist-folding side plate, and one of the front and rear left and right side plates other than the waist-folding side plate is directed toward the inside of the box via a hinge at the end of the bottom plate. Foldably connected, and if there is a remaining non-bending side plate, connect via a hinge so that it can be folded around the vertical axis center toward the outside of the box sequentially from the one adjacent to one non-bending side plate At the same time, the lid plate can be freely folded out of the box around the horizontal axis at the upper end of one of the waist broken side plates Characterized in that are linked.
[0009]
According to the configuration of the first aspect, the six plates of the bottom plate, the front and rear side plates, the left and right side plates, and the lid plate are all hingedly connected, so that the plates can be connected to each other in the box operating state or in the folded storage state. Are not separated from each other, so that there is no inconvenience that one of the plates has been lost or parts are missing. When there are two or more non-broken side plates, except for those hinged to the bottom plate, they can be folded around the vertical axis toward the outside of the box. From the front side plate (see FIGS. 4 and 7 (a)) which can be opened and swung, it is possible to take in and out the stored items separately from the openable and closable cover plate.
[0010]
In addition, the bottom plate is integrated with the lower side plate of at least one of the four sides around the at least one side, and is reinforced with a channel-shaped cross section instead of a simple flat plate, so that the strength of the bottom plate is improved. The rigidity itself is improved, and when assembled as a box, adjacent hinge connection points are displaced in the vertical or horizontal direction on the reinforced side (the axes P1 and P4 in FIG. 10). ), Which is advantageous in terms of shape-retaining strength, since distortion at the hinge connection portion is not easily amplified. In addition, since any board can be assembled and folded by swinging movement by hinge connection, it is possible to easily perform the assembling and folding operations of the box by only one operator.
[0011]
As a result, the strength and rigidity of the box are improved by integrating at least one to three sides of the bottom plate with the lower side plate of the waist-folding side plate, and the contents can be transported more stably, and all hinges are connected. Due to the structure, there is no risk of losing parts, and it can be easily assembled and compactly folded and stored by one worker, and a folding storage box excellent in operability and reliability can be provided.
[0012]
According to the second aspect of the present invention, in the configuration of the first aspect, the pair of plates hinged to each other so as to be foldable outwardly of the box are assembled as a box with their hinge-connected side end faces. It is characterized in that it is in a state of surface contact in the assembled assembling operation state.
[0013]
According to the configuration of the second aspect, for example, plates that are hinged and adjacent to each other are in close surface contact with inclined end surfaces inclined at 45 degrees (see 1t and 4t in FIG. 3). Since the stopper function for preventing further swinging into the box from the assembly operation state is performed with a large load area, swinging can be reliably controlled and an operation touch with a sense of moderation can be obtained.
[0014]
As a result, between the plates that are hinged to be foldable outside the box, reliable overswing control can be performed and distortion can be reduced, so that the strength and rigidity of the box can be substantially increased, and It is possible to provide a tatami accommodation box that also provides a moderate and favorable swing operation feeling. In addition, by making surface contact, the hermeticity and heat insulation inside the box are maintained.
[0015]
According to the third aspect of the present invention, in the configuration of the second aspect, the left or right side plate and the rear side plate are set as hip bent side plates, and the non-hip bent side plate of the left or right side plate is replaced with one non-hip bent side plate. In addition to the side plates, the one non-bending side plate and the front side plate and the rear side plate and the lid plate are hinged to each other so as to be foldable outside the box.
[0016]
According to the configuration of claim 3, two sides adjacent to each other among the four sides of the bottom plate are integrated with the lower side plate of the bent side plate, and the lid plate and the front side plate are openable and closable for taking in and out of stored items. The front side plate can be opened horizontally around the new vertical axis, so there are two easy-to-operate doors at the top and front, while improving strength and rigidity moderately, making it easier to handle and more convenient. Can be a storage box.
[0017]
The folding storage box according to claim 4 is characterized in that, in the configuration of claims 1 to 3, a hook-and-loop fastener that acts across adjacent ones of the bottom plate, the cover plate, and the front, rear, left and right side plates is provided. It is assumed that.
[0018]
According to the configuration of the fourth aspect, the operation state assembled in the box is maintained by the hooking engagement function of the hook-and-loop fastener, and the box state is made relatively strong while making the hook-and-loop fastener extremely simple attachment / detachment operation. A folding storage box which can be maintained and is excellent in shape retention can be obtained.
[0019]

[0028]
That is, if the configuration of the folding cold storage box A is expressed according to the description of claim 1, an example of the rear side plate 4 and the right side plate 6 (an example of “one to three side plates of the front, rear, left and right side plates”) ) Are directed toward the inside of the box around the horizontal axes P1 and P3 via hinges 7 and 9 at the upper ends of the lower side plates 4a and 6a integrated with the end of the bottom plate 2 and the upper ends of the lower side plates 4a and 6a. The left side plate 5 (an example of "one of the non-bending side plates other than the waist bending side plate of the front, rear, left and right side plates") is configured as a waist bending side plate including upper side plates 4b and 6b which are foldably connected to each other. Is connected to an end of the bottom plate 2 via a hinge 10 so as to be foldable toward the inside of the box. Then, the front side plate 3 (an example of the “remaining non-bending side plate”) is hinged to the left side plate 5 (an example of the “one non-bending side plate”) so as to be foldable around the longitudinal axis Q1 toward the outside of the box. 11, and the lid plate 1 is connected to the upper end of the rear side plate 4 (an example of "one of the bent side plates") so as to be foldable outwardly of the box around the horizontal axis P1.
[0029]
As shown in FIG. 14, each of the plates 1 to 6 has a sandwich-structure base material in which a polyethylene independent foam 20 as an example of a heat insulating material is sandwiched between a pair of thin polypropylene hollow resin plates 21 and 21. Is covered with a synthetic resin foam sheet 22 and a synthetic resin sheet 23 such as PVC tarpaulin. Each of the seats 13 to 19 and a portion to be connected are provided with a hook-and-loop fastener F including an engaging-side fastener k and an engaged-side fastener h. Is set. Next, a folding procedure of the folding storage box A will be described.
[0030]
First, from the use state as a box shown in FIGS. 1 to 3, the hook-and-loop fastener F of the left and right sheets 17 and 18 is peeled off, and then the lid plate 1 is rotated around the second horizontal axis P2 using the second hinge 8. Then, the outer side plate 4 swings (opens and swings), and folds along the outer surface of the rear side plate 4 as shown in FIG.
[0031]
Next, after the hook-and-loop fastener F of the sheet 19 is peeled off, the front plate portion 3b is separated from the substrate portion 3a while the substrate portion 3a is bent outward and oscillated about the first longitudinal center Q1 with respect to the left side plate 5. As shown in FIG. 9, the substrate portion 3a is fitted along the outer surface of the left side plate 5, and the front plate portion 3b is fitted along the inner surface of the substrate portion 3a. Fold the front side plate 3 to the state.
[0032]
Then, after the hook-and-loop fastener F of the left sheets 13 and 14 is peeled off, the left side plate 5 with the front side plate 3 in the folded state is bent inward around the fourth horizontal axis P4 using the fourth hinge 10. By swinging, as shown in FIG. 10, it is folded along the upper surface of the bottom plate 2A. At this time, the height position of the outer surface (upper surface) of the uppermost tip plate portion 3b is set to be the same as or slightly lower than the height of the third horizontal axis P3.
[0033]
Next, after the hook-and-loop fastener F of the right sheets 13 and 14 is peeled off, the upper right plate 6b is bent inwardly around the third horizontal axis P3 using the third hinge 9, and is shown in FIG. Thus, it is folded along the outer surface (upper surface) of the front plate portion 3b. At this time, the height of the outer surface of the upper right side plate 6b is set to be the same or slightly lower than the height of the first horizontal axis P1.
[0034]

The cover plate 1 is foldably connected to the inside of the box via the inner side, and the cover plate 1 is folded to the outside of the box around the horizontal axis P2 on the upper end of the rear plate 4 (an example of "one of the waist folded side plates"). A folding storage box A having a freely connected structure may be used.
[0037]
This case corresponds to a case where there is no “remaining non-bending side plate” referred to in claim 1. Further, as shown in FIG. It may be composed of a substrate part 1a hinged and connected to an inclined end face 1t that is in surface contact and a front plate part 1b hinged so as to be able to bend freely.
[0038]
(2) As shown in FIG. 16, the folding storage box A has a rear plate 4 (an example of “one of the front, rear, left and right side plates”) integrated with an end of the bottom plate 2. The left side plate 5 comprises a side plate 4a and an upper side plate 4b connected to the upper end of the lower side plate 4a via a hinge so as to be foldable inwardly around the horizontal axis P1 toward the inside of the box. (An example of “one of the non-hip-folded side plates other than the hip-folded side plate of the left, right, left and right side plates”) is foldably connected to the end of the bottom plate 2 inwardly of the box via a hinge, The front plate 3 is connected to the left plate 5 and the right plate 6 is connected to the front plate 3 via hinges so as to be foldable around the longitudinal axes Q1 and Q3 toward the outside of the box. Is connected to the upper end of the rear side plate 4 (an example of “one of the waist broken side plates”) so as to be foldable outside the box around the horizontal axis P2. It may be tatami storage box A. In this case, the “remaining non-bending side plate” described in claim 1 corresponds to the front side plate 3 and the right side plate 6.
[0039]
(3) As shown in FIG. 4, the connection sheet provided on the left and right of the rear side plate 4 is a single vertically long connection having a length such that a hook-and-loop fastener straddles the upper rear plate 4b and the upper right side plate 6b. The structure in which the sheet 13 is provided may be either a structure in which the upper connection sheet 13 and the lower connection sheet 14 are divided and provided as a pair, as shown in FIG. Further, the folding storage box A is applicable not only to the above-described heat insulation and cooling (heat insulation) box, but also to a storage box for clothes and shoes, or to a storage box that does not require heat insulation, such as a tissue case or toilet paper. It is free.
[0040]
Further, as for the end faces (1t and 4t, etc.) which bend and oscillate about 270 degrees inward, the contact areas between 45 degrees are the most convenient because the largest contact area can be obtained. It is also possible to use a combination such as 60 ° and 60 °, and this configuration is expressed in claim 2 as “the surface is brought into surface contact in the assembling operation state assembled as a box”.
