Description

【０００１】
【発明の属する技術分野】
本発明は、組み立て式コンテナの技術分野に属する。
【０００２】
【従来の技術】
荷物運搬用の容器として底板と４枚の側板とを備える組み立て式コンテナが知られており、例えば特開２００１−２０６３６５公報には４枚の側板のうち向かい合う２枚の側板を底板に分離可能に連結する組み立て式コンテナが開示されている。
【０００３】
この組み立て式コンテナの底板には２枚の壁状の突起が設けられている。壁状の突起の上部には係合溝が設けられている。この係合溝の底には係合受け段部が形成されており、係合溝の内側の内縁には抜け防止板が水平向きに設けられている。また壁状の突起の上部には係合溝の外側の内縁に連続する嵌合板が垂直上向きに設けられている。
【０００４】
一方、底板に分離可能に連結される２枚の側板の下端には係合溝に係合する係合部と嵌合板が差し込まれる嵌合溝とが設けられている。この係合部の下面には係合段部が設けられており、係合部の一部は組み立て式コンテナの内側方向を向いた突起となっている。
【０００５】
側板を底板に取り付けるには、係合部の突起を組み立て式コンテナの内側に向けて係合溝の上方に位置させながら側板を組み立て式コンテナの内側に傾け、係合部を突起から係合溝に差し入れる。次に係合部が係合溝に当たっているところを支点にして側板を底板に対して垂直に起こす。このとき嵌合板と嵌合溝とが嵌合されると同時に係合段部が係合受け段部と噛み合い、側板が底板に取り付けられる。尚、側板は自立し倒れなくなる。この状態で側板を引き上げる力が側板に働いても係合部の突起が抜け防止板に当たるので、係合部は係合溝から抜けない。
【０００６】
側板を底板から取り外すときは、係合部の突起が抜け防止板に当たるまで側板を引き上げる。このとき嵌合板が嵌合溝から外されると同時に係合受け段部と係合段部との噛み合いが解かれる。次に突起が抜け防止板に当たっているところを支点にして側板を組み立て式コンテナの内側の方に傾け、係合部を係合溝から引き抜けば、側板が底板から取り外される。
【０００７】
【発明が解決しようとする課題】
上記の組み立て式コンテナの底板と側板との連結部分は係合溝及び係合部の他に嵌合板、嵌合溝、係合段部及び係合受け段部を備えており、そのため複雑な形状となっていた。
【０００８】
本発明は単純な連結構造を有する組み立て式コンテナを提供することを目的としている。
【０００９】
【課題を解決するための手段及び効果】
上記課題を解決するために請求項１記載の組み立て式コンテナは、方形の底板と４枚の側板とを備え、組み立て及び分解できる組み立て式コンテナであって、前記側板のうちの向かい合う一組の側板それぞれの下部に設けられた側板側連結部と前記底板に設けられた底板側連結部とからなり前記側板のうちの向かい合う一組の側板を前記底板に分離可能に連結するための連結構造を有する組み立て式コンテナにおいて、前記底板側連結部は、前記底板の上面に平行な内縁支持面と、該内縁支持面よりも前記底板の辺側に位置し前記底板の上面に平行な外縁支持面と、前記内縁支持面との間の角度が鈍角をなし前記内縁支持面の前記外縁支持面側に連続する下側溝壁面と該下側溝壁面に平行で前記下側溝壁面の上方に位置する上側溝壁面とを有し前記内縁支持面と前記外縁支持面との間に開口する差込溝とを備え、前記側板側連結部は、前記側板の下端に形成されて取り付け時に前記内縁支持面と合わさる内縁被支持面と、前記側板の下端に形成されて取り付け時に前記外縁支持面と合わさる外縁被支持面と、前記内縁被支持面との間の角度が前記内縁支持面と前記下側溝壁面との間の角度と同じで前記内縁被支持面の前記外縁被支持面側の辺に連続する下側差込面と該下側差込面に平行で前記下側差込面の上方に位置し前記下側差込面との間の距離が前記下側溝壁面と上側溝壁面との間の距離と同じである上側差込面とを有し前記内縁被支持面と前記外縁被支持面との間から延出され取り付け時には前記差込溝に差し込まれる差込部とを備えることを特徴とする。
【００１０】
底板側連結部と側板側連結部とは差込部が差込溝に差し込まれ、差込部の内側（内縁被支持面）が差込溝の内側（内縁支持面）と、差込部の外側（外縁被支持面）が差込溝の外側（外縁被支持面）とそれぞれ合わさることで連結される。また差込部が差込溝から引き抜かれれば底板側連結部と側板側連結部との連結は容易に分離される。
【００１１】
これら底板側連結部と側板側連結部とが連結されると差込部は差込溝にはめられ、差込部の内側は差込溝の内側に、差込部の外側は差込溝の外側にそれぞれ支えられるので、側板側連結部を有する側板は自立する。
また、側板側連結部を有する側板は底板側連結部と側板側連結部との連結解除によって底板から分離されるが、その内側に他の側板を隣接させて取り付けるなどして差込溝の傾斜に沿った方向への動きを規制すれば、底板との連結が解除されない。
【００１２】
底板側連結部は底板に開けられた差込溝と差込溝の両側にそれぞれ位置する内縁支持面及び外縁支持面とを備え、一方側板側連結部は向かい合う２枚の側板それぞれの下端に設けられている差込部と差込部の両側にそれぞれ位置する内縁被支持面及び外縁被支持面とを備えればよいので、両者からなる連結構造を単純にできる。
【００１３】
差込部の下側差込面と上側差込面との間の距離は差込溝の下側溝壁面と上側溝壁面との間の距離に等しいので、差込部を滑らかに動く状態で差込溝にはめることができる。但し、差込部が滑らかに動くためには差込部と差込溝との間に若干の隙間が必要である。
【００１４】
請求項２記載の組み立て式コンテナは、請求項１記載の組み立て式コンテナにおいて、前記底板側連結部は、前記底板の上側に形成された壁状の突起に設けられていることを特徴とする。
底板の上側には２枚の壁状の突起が向かい合って形成されているので、側板側連結部を有する側板の高さ及び他の側板の横幅をそれぞれ向かい合う壁状突起の間の距離よりも短く設定すれば、これら側板を向かい合う壁状突起の間に収納できる。
【００１５】
請求項３記載の組み立て式コンテナは、請求項２記載の組み立て式コンテナにおいて、前記底板の上面からの高さは、前記内縁支持面の方が前記外縁支持面よりも低いことを特徴とする。
差込溝の内側（内縁支持面）と外側（外縁支持面）との間には段差が形成されるので、差込部を差込溝の内側の上に一旦のせたのち差込溝の外側の方へ滑らせて段差に当てることで差込部と差込溝とを容易に合わせることができ、差込部を差込溝に差し入れやすくなる。
【００１６】
請求項４記載の組み立て式コンテナは、請求項１ないし３のいづれか記載の組み立て式コンテナにおいて、外縁支持面と上側溝壁面との間には外縁支持面に対して垂直な外縁切り口が位置するので、内縁支持面と外縁切り口の間が差込溝への案内部となり、差込部を差込溝に差し入れやすい。
【００１７】
請求項５記載の組み立て式コンテナは、請求項１ないし４のいづれか記載の組み立て式コンテナにおいて、差込部は上側差込面に連続して外縁被支持面に対して垂直な方向に差込部切り口を有するので、差込部の先端は面取りされて細くなり、差込溝に差し入れやすい。
【００１８】
【発明の実施の形態】
次に本発明の実施例により発明の実施の形態を説明する。
【００１９】
【実施例】
図８に示すように、組み立て式コンテナ１は底板１０、連結側板２６、差込側板３８及び天板５２から構成されている。
図１に示すように、底板１０は四辺枠１２、方形の上板１４及び方形の下板１６から構成されている。この四辺枠１２は２本の連結枠部材１８、２本の支持枠部材２０及び４個のコーナー部材２２から構成されている。
【００２０】
図３（ａ）に示すように、連結枠部材１８は平板部１８ａの上面において壁状の突起部１８ｂが平板部１８ａの一辺に沿って設けられた形状をしており、平板部１８ａの突起部１８ｂが設けられた側は連結枠部材１８の外側となる。
突起部１８ｂの上部には差込溝１８ｃが設けられている。この差込溝１８ｃは互いに平行な下側溝壁面１８ｈと上側溝壁面１８ｉとを有しており、またその開口から奥の方に行くに従って連結枠部材１８の外側へ向けて傾いている。
【００２１】
突起部１８ｂの上部における差込溝１８ｃから内側には内縁支持面１８ｄが下側溝壁面１８ｈに連続して形成されている。なお、内縁支持面１８ｄと下側溝壁面１８ｈとの間の角度θ１は鈍角となっている。また、突起部１８ｂの上部における差込溝１８ｃから外側には垂直接触面１８ｆが上側溝壁面１８ｉに連続して形成されている。なお、平板部１８ａからの高さは内縁支持面１８ｄの方が外縁支持面１８ｅよりも低い。
【００２２】
図１に戻り、連結枠部材１８の外側には面ファスナーのループ側１８ｇが取り付けられている。
一方、支持枠部材２０は平板部２０ａの上面に壁状の突起部２０ｂを平板部２０ａの一辺に沿って設けた形状をしている。この突起部２０ｂの上端には差込側板支持面２０ｃが形成されている。
【００２３】
これら２本の支持枠部材２０は平板部２０ａを内側にした向かい合わせの状態で上板１４の上面の縁にそれぞれ配されており、平板部２０ａと上板１４の上面の縁とを貫通したリベット２４により上板１４の上面の縁と締結されている。支持枠部材２０の端部間には連結枠部材１８が平板部１８ａを内側にして向かい合わせに配され、連結枠部材１８は平板部１８ａと上板１４とを貫通したリベット２４により上板１４と締結されている。連結枠部材１８と支持枠部材２０とが突き合わされている隅部にはコーナー部材２２が配されており、コーナー部材２２と連結枠部材１８の端部とは両者を貫通したリベット２４により締結され、コーナー部材２２と支持枠部材２０の端部とは両者を貫通したリベット２４により締結されている。
【００２４】
また、上板１４の下面には下板１６が接着剤などで固定されている。
図２に示すように、連結側板２６は方形の板２８、上枠部材３０、下枠部材３２、右枠部材３４及び左枠部材３６から構成されている。
板２８の一方の面には面ファスナーのループ側２８ａが取り付けられており、この面が連結側板２６の外側の面となる。
【００２５】
図３（ｂ）に示すように、下枠部材３２の上部には凹溝３２ａが設けられており、板２８の下部が差し込まれて連結されている。この下枠部材３２の板２８に垂直な方向の厚みは突起部１８ｂの内外壁面間の厚みに等しい。
下枠部材３２の下部には差込部３２ｂが設けられており、差込部３２ｂは先端に行くに従って連結側板２６の外側に近づく方向に傾いている。この差込部３２ｂは互いに平行な下側差込面３２ｇと上側差込面３２ｈとを有しており、差込部３２ｂの先端には垂直面３２ｃが形成されている。差込部３２ｂの下側差込面３２ｇと上側差込面３２ｈとの間の幅は差込溝１８ｃの下側溝壁面１８ｈと上側溝壁面１８ｉとの間の幅よりも若干小さくなっており、差込部３２ｂを滑らかに動く状態で差込溝１８ｃに差し込むことができる。また、差込部３２ｂの長さは差込溝１８ｃの深さよりも短くなっており、差込部３２ｂを差込溝１８ｃに差し込むと、差込部３２ｂの全体が差込溝１８ｃに差し込まれる。
【００２６】
下枠部材３２の下部における差込部３２ｂの内側には内縁被支持面３２ｄが下側差込面３２ｇに連続して形成されている。なお、内縁被支持面３２ｄと下側差込面３２ｇとの間の角度θ２は角度θ１に等しい。この内縁被支持面３２ｄは差込部３２ｂが差込溝１８ｃに差し込まれたときには内縁支持面１８ｄに合わさる。
【００２７】
下枠部材３２の下部における差込部３２ｂの外側には垂直接触面３２ｆが上側差込面３２ｈに連続して形成されている。この垂直接触面３２ｆは差込部３２ｂが差込溝１８ｃに差し込まれたときには垂直接触面１８ｆに合わさる。
下枠部材３２の下部における垂直接触面３２ｆの外側には外縁被支持面３２ｅが垂直接触面３２ｆに連続して形成されている。この外縁被支持面３２ｅは差込部３２ｂが差込溝１８ｃに差し込まれたときには外縁支持面１８ｅに合わさる。
【００２８】
差込部３２ｂの全体が差込溝１８ｃに差し込まれると内縁被支持面３２ｄが内縁支持面１８ｄと、外縁被支持面３２ｅが外縁支持面１８ｅと、垂直接触面３２ｆが垂直接触面１８ｆとそれぞれ合わさり連結枠部材１８と下枠部材３２とが連結される（図３（ｃ））。
【００２９】
図示しないが、上枠部材３０の下部、右枠部材３４の左部及び左枠部材３６の右部には凹溝３２ａと同様の凹溝がそれぞれ設けられており、図２に示すように、それぞれ板２８の上部、右部及び左部が差し込まれて連結されている。板２８が差し込まれた各枠部材３０、３２、３４、３６の重なり合う端部同士はこの重なり合う部分を貫通したリベット２４によって締結されている。また、右枠部材３４の右部及び左枠部材３６の左部にはそれぞれ取付溝３４ａ、３６ａが設けられており、右枠部材３４の右側面及び左枠部材３６の左側面にはそれぞれピン穴３４ｂ、３６ｂが開けられている。
【００３０】
図４に示すように、差込側板３８は方形の板４０、上枠部材４２、下枠部材４４、右枠部材４６及び左枠部材４８から構成されている。
上枠部材４２の下部、下枠部材４４の上部、右枠部材４６の左部及び左枠部材４８の右部には凹溝３２ａと同様の凹溝がそれぞれ設けられており、それぞれ板４０の上部、下部、右部及び左部が差し込まれて連結されている。板４０が差し込まれた各枠部材４２、４４、４６、４８の重なり合う端部同士はこの重なり合う部分を貫通したリベット２４で連結されている。
【００３１】
下枠部材４４の板４０に対して垂直な方向の厚みは突起部２０ｂの内外壁面間の厚みに等しい。また、右枠部材４６の板４０に対して垂直な方向の幅及び左枠部材４８の板４０に対して垂直な方向の幅はそれぞれ取付溝３６ａ、３４ａの溝壁間の幅よりも若干小さくなっており、右枠部材４６及び左枠部材４８をそれぞれ取付溝３６ａ、３４ａに差し入れることができる。
【００３２】
右枠部材４６及び左枠部材４８には係止部５０が取り付けられており、係止部５０が取り付けられた面が差込側板３８における外側となる。この係止部５０は平板５０ｂ、５０ｃ、軸５０ｄから構成される蝶番であり、平板５０ｃを貫通したビス５０ｅにより右枠部材４６及び左枠部材４８それぞれに固定されている。また、平板５０ｂにはピン５０ａが設けられている。このピン５０ａの直径はピン穴３４ｂ、３６ｂの穴径よりも若干小さくなっている。
【００３３】
係止部５０が右枠部材４６及び左枠部材４８それぞれに取り付けられる位置は右枠部材４６及び左枠部材４８がそれぞれ取付溝３６ａ、３４ａに差し入れられた状態において、平板５０ｂと共に回動したピン５０ａがそれぞれピン穴３６ｂ、３４ｂに入れられる位置である。
【００３４】
図５に示すように、天板５２は方形の板５４，各２本の天板枠部材５６、５８及び４個のコーナー部材６０から構成されている。
天板枠部材５６、５８には凹溝３２ａと同様の凹溝がそれぞれ設けられており、板５４の対応する端部それぞれが差し込まれて連結されている。天板枠部材５６と天板枠部材５８が突き合わされている隅部にはコーナー部材６０が配されており、コーナー部材６０と天板枠部材５６の端部とは両者を貫通したリベット２４により締結され、同様にコーナー部材６０と天板枠部材５８の端部とは両者を貫通したリベット２４により締結されている。
【００３５】
また、天板枠部材５６には帯状の面ファスナーのフック側５６ａが取り付けられており、この面ファスナーのフック側５６ａと底板１０の面ファスナーのループ側１８ｇまたは連結側板２６の面ファスナーのループ側２８ａとを接合させることができる。
【００３６】
次に組み立て式コンテナ１の組み立て手順を説明する。
初めに２枚の連結側板２６を底板１０に取り付ける。連結側板２６をその差込部３２ｂが下側になり面ファスナーのループ側２８ａが組み立て式コンテナ１外部側になる状態で底板１０の連結枠部材１８の上方に位置させる。
【００３７】
連結側板２６の差込部３２ｂを連結枠部材１８の内縁支持面１８ｄの上に一旦のせ、連結側板２６をこの連結枠部材１８の外側の方へ動かす。この連結側板２６の動きに伴って差込部３２ｂが連結枠部材１８の外側の方に向かって内縁支持面１８ｄ上を滑らされ、差込部３２ｂの垂直面３２ｃが垂直接触面１８ｆに当てられる。
【００３８】
差込部３２ｂは差込溝１８ｃと同じ角度で傾斜しており、また差込部３２ｂの幅は差込溝１８ｃの幅よりも若干小さいので、差込部３２ｂは垂直接触面１８ｆに連続する差込溝１８ｃにそのまま落ち込むように差し込まれる。
差込部３２ｂの全体が差込溝１８ｃ内に差し込まれると内縁被支持面３２ｄが内縁支持面１８ｄと、外縁被支持面３２ｅが外縁支持面１８ｅと、垂直接触面３２ｆが垂直接触面１８ｆとそれぞれ合わさり、連結枠部材１８と下枠部材３２とが連結される（図３（ｃ））。この連結枠部材１８と下枠部材３２との連結により連結側板２６は底板１０に取り付けられて自立する。
【００３９】
このようにして２枚の連結側板２６が底板１０に向かい合わせの状態で取り付けられると図６の状態となる。
次に２枚の差込側板３８を向かい合う連結側板２６の間に取り付ける。差込側板３８をその下枠部材４４が下側になり係止部５０が組み立て式コンテナ１の外部側になる姿勢とし、右枠部材４６及び左枠部材４８がそれぞれ連結側板２６の取付溝３６ａ、３４ａの上方に位置され且つ下枠部材４４が底板１０の支持枠部材２０の上方に位置されるようにする。そして差込側板３８の右枠部材４６及び左枠部材４８をそれぞれ取付溝３６ａ、３４ａに差し入れ、そのまま差込側板３８を落とし込んで支持枠部材２０の差込側板支持面２０ｃにのせる。
【００４０】
差込側板３８は向かい合う２枚の連結側板２６の間に取り付けられて連結側板２６の差込溝１８ｃに沿った方向の動きを規制するので、差込部３２ｂが差込溝１８ｃから抜けることがなく、連結側板２６は底板１０から分離されなくなる。
差込側板３８の係止部５０の平板５０ｂを回動させてピン５０ａをそれぞれ連結側板２６のピン穴３４ｂ、３６ｂに入れる。このピン５０ａとピン穴３４ｂ、３６ｂとの係合によって差込側板３８と連結側板２６とが連結される。
【００４１】
このようにして２枚の差込側板３８が向かい合う連結側板２６の間に取り付けられると図７の状態となり、荷物を内部に収納できる。
また、必要により天板５２を連結側板２６及び差込側板３８からなる４面の壁の上部に取り付けることができる。
【００４２】
天板５２を４面の壁の上部に取り付けるには、まず面ファスナーのフック側５６ａを有する天板枠部材５６が面ファスナーのループ側２８ａを有する連結側板２６の上方に、天板枠部材５８が差込側板３８の上方にそれぞれ位置するようにする。次に、天板部材５６を連結側板２６の上に、天板部材５８を差込側板３８の上にそれぞれのせて天板５２を４面の壁の上部に取り付ける。これに伴い天板５２の四隅のコーナー部材６０の下部がそれぞれ連結側板２６及び差込側板３８の外側に位置され、天板５２が４面の壁に対してずれなくなる
また、天板５２の面ファスナーのフック側５６ａと連結側板２６の面ファスナーのループ側２８ａとを接合させると天板５２が連結側板２６に固定される。
【００４３】
このように天板５２が４面の壁の上部に取り付けられると図８に示すような組み立て式コンテナ１が組み上がる。
組み立て式コンテナ１は組み立てとは逆の手順により天板５２を連結側板２６及び差込側板３８からなる４面の壁の上部から取り外し、続いて差込側板３８を向かい合う連結側板２６の間から引き抜き、更に連結側板２６を引き上げて底板１０との連結を解くことで分解される。
【００４４】
また、取り外された連結側板２６及び差込側板３８を横向きにして底板１０の四辺枠１２の内側に納め、天板５２の四隅のコーナー部材６０下部が底板１０の四隅のコーナー部材２２の外側にそれぞれ位置させ、天板５２の面ファスナーのフック側５６ａと底板１０の面ファスナーのループ側１８ｇとを接合させると図９に示すような折り畳まれた組み立て式コンテナ１となる。
【００４５】
本実施例の組み立て式コンテナ１の底板１０は連結枠部材１８に差込溝１８ｃ、内縁支持面１８ｄ及び外縁支持面１８ｅを備え、連結側板２６は下枠部材３２に差込部３２ｂ、内縁被支持面３２ｄ及び外縁被支持面３２ｅを備えている。
底板１０と連結側板２６との連結時には差込部３２ｂ全体が差込溝１８ｃにはめられ、内縁被支持面３２ｄ、外縁被支持面３２ｅがそれぞれ内縁支持面１８ｄ、外縁支持面１８ｅに合わさり支えられるので、連結側板２６は底板１０に分離可能に連結されて底板１０上に自立する。
【００４６】
また、底板１０と連結側板２６との連結構造を単純にすることができる。
差込部３２ｂの先端には垂直面３２ｃが形成されているので、差込部３２ｂの先端は面取りされて細くなり、差込部３２ｂの先端を差込溝１８ｃに差し入れるのが容易となる。
【００４７】
平板部１８ａからの高さは内縁支持面１８ｄの方が外縁支持面１８ｅよりも低いために内縁支持面１８ｄと外縁支持面１８ｅとの間に段差が形成されるので、差込部３２ｂを差込溝１８ｃに差し入れる際に、差込部３２ｂを内縁支持面１８ｄの上に一旦のせたのち外縁支持面１８ｅの方へ滑らせて段差に当てることで差込部３２ｂと差込溝１８ｂとを容易に合わせることができる。
【００４８】
外縁支持面１８ｅと差込溝１８ｃとの間には垂直接触面１８ｆが外縁支持面１８ｅと差込溝１８ｃとに連続して形成されているので、内縁支持面１８ｄと垂直接触面１８ｆの間が差込溝１８ｃへの案内部となり、差込部３２ｂが差込溝１８ｃに差し込まれる際には差込部３２ｂはこの案内部によって差込溝１８ｃに案内される。
【００４９】
差込部３２ｂの両差込面３２ｇ、３２ｈ間の幅は差込溝１８ｃの両溝壁面１８ｈ、１８ｉ間の幅よりも若干小さいので、差込溝１８ｃにはめられた差込部３２ｂは差込溝１８ｃ内でがたつかず、且つ滑らかに動かせる。
底板１０に連結された連結側板２６の取付溝３４ａ、３６ａには差込側板３８が差し込まれ、連結側板２６の差込溝１８ｃに沿った動きが差込側板３８によって規制されるので、差込部３２ｂが差込溝３２ｃから抜けることがなく、その結果底板１０との連結が解除されない。
【００５０】
底板１０には四辺枠１２と下板１４とに囲まれた場所が形成されるので、この場所に４枚の各側板２６、３８を納めることができる。
以上、実施例に従って本発明の実施の形態について説明したが、本発明はこのような実施例に限定されるものではなく、本発明の要旨を逸脱しない範囲でさまざまに実施できるのはいうまでもない。
【００５１】
実施例の突起部１８ｂの上部には差込溝１８ｃが設けられているが、差込溝１８ｃの底部の少なくとも一部が貫通していてもよい。
実施例の差込部３２ｂの先端には垂直面３２ｃが形成されているが、先端が細くなる形状であれば垂直面に限られない。

Further, a hook side 56a of a belt-shaped surface fastener is attached to the top plate frame member 56. The hook side 56a of the surface fastener and the loop side 18g of the surface fastener of the bottom plate 10 or the loop side of the surface fastener of the connecting side plate 26 are attached. 28a can be joined.
[0036]
Next, the assembly procedure of the assembly-type container 1 will be described.
First, the two connecting side plates 26 are attached to the bottom plate 10. The connecting side plate 26 is positioned above the connecting frame member 18 of the bottom plate 10 with the insertion portion 32b on the lower side and the loop side 28a of the hook-and-loop fastener on the outer side of the assembling type container 1.
[0037]
The insertion portion 32 b of the connection side plate 26 is temporarily placed on the inner edge support surface 18 d of the connection frame member 18, and the connection side plate 26 is moved toward the outside of the connection frame member 18. With the movement of the connection side plate 26, the insertion portion 32b is slid on the inner edge support surface 18d toward the outside of the connection frame member 18, and the vertical surface 32c of the insertion portion 32b is applied to the vertical contact surface 18f. .
[0038]
The insertion portion 32b is inclined at the same angle as the insertion groove 18c, and the width of the insertion portion 32b is slightly smaller than the width of the insertion groove 18c, so that the insertion portion 32b is continuous with the vertical contact surface 18f. It is inserted so as to fall into the insertion groove 18c as it is.
When the entire insertion portion 32b is inserted into the insertion groove 18c, the inner edge supported surface 32d is the inner edge support surface 18d, the outer edge supported surface 32e is the outer edge support surface 18e, and the vertical contact surface 32f is the vertical contact surface 18f. The connecting frame member 18 and the lower frame member 32 are connected to each other (FIG. 3C). By connecting the connecting frame member 18 and the lower frame member 32, the connecting side plate 26 is attached to the bottom plate 10 and becomes independent.
[0039]
When the two connecting side plates 26 are attached to the bottom plate 10 so as to face each other, the state shown in FIG. 6 is obtained.
Next, the two insertion side plates 38 are attached between the connecting side plates 26 facing each other. The insertion side plate 38 is in a posture in which the lower frame member 44 is on the lower side and the locking portion 50 is on the outer side of the assembling container 1, and the right frame member 46 and the left frame member 48 are respectively attached to the attachment grooves 36 a of the connection side plate 26. , 34 a and the lower frame member 44 is positioned above the support frame member 20 of the bottom plate 10. Then, the right frame member 46 and the left frame member 48 of the insertion side plate 38 are inserted into the mounting grooves 36a and 34a, respectively, and the insertion side plate 38 is dropped as it is to be placed on the insertion side plate support surface 20c of the support frame member 20.
[0040]
Since the insertion side plate 38 is attached between the two connection side plates 26 facing each other and restricts the movement of the connection side plate 26 in the direction along the insertion groove 18c, the insertion portion 32b may come out of the insertion groove 18c. The connecting side plate 26 is not separated from the bottom plate 10.
The flat plate 50b of the locking portion 50 of the insertion side plate 38 is rotated to put the pins 50a into the pin holes 34b and 36b of the connection side plate 26, respectively. The insertion side plate 38 and the connection side plate 26 are connected by the engagement between the pin 50a and the pin holes 34b and 36b.
[0041]
When the two insertion side plates 38 are attached between the connecting side plates 26 facing each other in this way, the state shown in FIG. 7 is obtained, and the luggage can be stored inside.
Further, if necessary, the top plate 52 can be attached to the upper part of the four walls formed by the connection side plate 26 and the insertion side plate 38.
[0042]
In order to attach the top plate 52 to the upper part of the four walls, the top plate frame member 56 having the hook side 56a of the hook-and-loop fastener is first placed above the connecting side plate 26 having the loop side 28a of the hook-and-loop fastener. Are positioned above the insertion side plate 38, respectively. Next, the top plate member 56 is placed on the connection side plate 26 and the top plate member 58 is placed on the insertion side plate 38, and the top plate 52 is attached to the upper part of the four walls. Accordingly, the lower portions of the corner members 60 at the four corners of the top plate 52 are positioned outside the connection side plate 26 and the insertion side plate 38, respectively, so that the top plate 52 is not displaced with respect to the four walls. When the hook side 56 a of the fastener and the loop side 28 a of the surface fastener of the connection side plate 26 are joined, the top plate 52 is fixed to the connection side plate 26.
[0043]
Thus, when the top plate 52 is attached to the upper part of the four walls, the assembly type container 1 as shown in FIG. 8 is assembled.
The assembling type container 1 removes the top plate 52 from the upper part of the four walls composed of the connecting side plate 26 and the insertion side plate 38 by the reverse procedure of the assembly, and then pulls out the insertion side plate 38 from between the connecting side plates 26 facing each other. Furthermore, it is disassembled by pulling up the connection side plate 26 and releasing the connection with the bottom plate 10.
[0044]
Further, the removed connecting side plate 26 and insertion side plate 38 are placed sideways inside the four-sided frame 12 of the bottom plate 10, and the lower corner members 60 at the four corners of the top plate 52 are placed outside the corner members 22 at the four corners of the bottom plate 10. When the hook side 56a of the hook-and-loop fastener of the top plate 52 and the loop side 18g of the hook-and-loop fastener of the bottom plate 10 are joined to each other, the assembled container 1 is folded as shown in FIG.
[0045]
The bottom plate 10 of the assembly type container 1 of the present embodiment is provided with the insertion groove 18c, the inner edge support surface 18d and the outer edge support surface 18e in the connection frame member 18, and the connection side plate 26 is connected to the lower frame member 32 with the insertion portion 32b and the inner edge cover. A support surface 32d and an outer edge supported surface 32e are provided.
When the bottom plate 10 and the connection side plate 26 are connected, the entire insertion portion 32b is fitted into the insertion groove 18c, and the inner edge supported surface 32d and the outer edge supported surface 32e are respectively supported by the inner edge support surface 18d and the outer edge support surface 18e. Therefore, the connecting side plate 26 is detachably connected to the bottom plate 10 and is self-supporting on the bottom plate 10.
[0046]
Further, the connection structure between the bottom plate 10 and the connection side plate 26 can be simplified.
Since the vertical surface 32c is formed at the distal end of the insertion portion 32b, the distal end of the insertion portion 32b is chamfered and becomes thin, and it is easy to insert the distal end of the insertion portion 32b into the insertion groove 18c. .
[0047]
Since the height from the flat plate portion 18a is lower at the inner edge support surface 18d than at the outer edge support surface 18e, a step is formed between the inner edge support surface 18d and the outer edge support surface 18e. When the insertion portion 32b is inserted into the insertion groove 18c, the insertion portion 32b is once placed on the inner edge support surface 18d and then slid toward the outer edge support surface 18e to be applied to the step, thereby inserting the insertion portion 32b and the insertion groove 18b. Can be easily adjusted.
[0048]
Since a vertical contact surface 18f is formed continuously between the outer edge support surface 18e and the insertion groove 18c between the outer edge support surface 18e and the insertion groove 18c, the space between the inner edge support surface 18d and the vertical contact surface 18f is formed. Becomes a guide part to the insertion groove 18c, and when the insertion part 32b is inserted into the insertion groove 18c, the insertion part 32b is guided to the insertion groove 18c by this guide part.
[0049]
Since the width between both the insertion surfaces 32g and 32h of the insertion portion 32b is slightly smaller than the width between both the wall surfaces 18h and 18i of the insertion groove 18c, the insertion portion 32b fitted into the insertion groove 18c is not inserted. It does not rattle in the recessed groove 18c and can be moved smoothly.
The insertion side plate 38 is inserted into the mounting grooves 34a and 36a of the connection side plate 26 connected to the bottom plate 10, and the movement along the insertion groove 18c of the connection side plate 26 is restricted by the insertion side plate 38. The portion 32b does not come out of the insertion groove 32c, and as a result, the connection with the bottom plate 10 is not released.
[0050]
Since a place surrounded by the four-sided frame 12 and the lower plate 14 is formed in the bottom plate 10, the four side plates 26 and 38 can be accommodated in this place.
The embodiments of the present invention have been described above according to the examples. However, the present invention is not limited to such examples, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention. Absent.
[0051]
Although the insertion groove 18c is provided in the upper part of the projection part 18b of an Example, at least one part of the bottom part of the insertion groove 18c may penetrate.
Although the vertical surface 32c is formed in the front-end | tip of the insertion part 32b of an Example, if it is a shape where a front-end | tip becomes thin, it will not be restricted to a vertical surface.
