Description

【０００１】
【発明の属する技術分野】
本発明は、合成樹脂製カバンに関するもので、合成樹脂で一体成型されるシェルとも称されている箱状本体と、同材質略同形の蓋体とを、一辺でヒンジ連結してカバンを構成する合成樹脂製カバンに関するものである。
【０００２】
【従来の技術】
従来、スーツケースやキャスターバッグ等に、箱状本体と箱状蓋体とを合成樹脂で成型したものを使用し、その一辺どうしをヒンジ連結するものが汎用されている。そして、最近では、この種合成樹脂製カバンを、リュックサックや手提げカバン、さらにはポシェットやウエストポーチ等の比較的小型なカバンにも応用されるようになってきている。
【０００３】
この種、合成樹脂製カバンの代表的な従来例を、図４を参照にして説明すると、先ず、金属枠製の中央メインフレーム７１と、同じく金属枠製の中央サブフレーム７２と、合成樹脂で一体成型した箱状のカバン本体１０と、同材質略同形の蓋体２０とで構成され、カバン本体１０の開口縁部１０ａには中央メインフレーム７１が、図５に示すように、鋲７４で鋲着され、蓋体２０には中央サブフレーム７２が鋲７４で鋲着され、中央メインフレーム７１と中央サブフレーム７２との外面側（図５では、同図の下方側がカバンの外面側となる。）には、鋲着部を覆うカバー帯７３、７３が被せられている。
【０００４】
上記カバン本体１０と蓋体２０とは、一辺（図４の左奥側辺部）部位が、図示していない蝶番等で枢着され、カバン本体１０と蓋体２０と両者の開口部が合わさって、カバン本体１０に蓋体２０が閉じ合わさるようにしてある。上記枢着される辺と対向する辺側には、中央サブフレーム７２側に係合フック片７５（図５参照）を、中央メインフレーム７１側に前記係合フック片７５を着脱可能に係止する係合着脱機構部７６を設けてある。
【０００５】
すなわち、従来のこの種合成樹脂製カバンは、所定の強度を有した中央メインフレーム７１及び中央サブフレーム７２と、この両者を着脱可能に係合する係合フック片７５と係合着脱機構部７６とが必要となる。さらに、体裁上、カバー帯７３、７３が必要となり、これらの部品で全体が重くなるという問題点を有している。この間題点を解決すべく、中央メインフレーム７１と中央サブフレーム７２とを改良する提案が種々行われており、例えば、特許文献１には、前記中央サブフレーム７２は省略し、中央メインフレームを組み立て式の合成樹脂材で成型し、この中央メインフレームには全周に渡って補強リブを設けることで、強靱性は損なわずに肉薄で軽量化できるようにしたものが提案されている。
【０００６】
上記合成樹脂製の中央メインフレームは充分な強度が得られ、軽量化も可能であることは容易に理解でき、スーツケース等の大型の合成樹脂製カバンには歓迎される提案であるが、キャスターバッグ等の比較的小型なカバンでは、なお、軽量化が要望されるもので、これら従来例の軽量化の最大の注目点は、どうしても金属部品を多く使用する必要性のある、図4及び図5に示す係合着脱機構部７６であるとされている。
【０００７】
【発明が解決しようとする課題】
そこで、本発明は、上記問題点に鑑みなされたもので、軽量化のために中央フレームを省略し、係合着脱機構部を軽量化が容易なスライドファスナーで代用した合成樹脂製カバンを提供することを課題としたものである。
【０００８】
【課題を解決するための手段】
本発明は、上記課題を達成するために、工業用ミシンの針が貫通できる合成樹脂材で成型した箱状のカバン本体１０と、同じく前記合成樹脂材で成型した箱状の蓋体２０とを、両者の開口縁部１０ａ、２０ａの一辺１１、２１どうしを枢着してなる合成樹脂製カバンにおいて、上記カバン本体１０の枢着部を除く開口縁部１０ａに、ゴム又は軟質合成樹脂で成型され、内面部３１と外面部３２とが略二つ折り状に連設された縁取体３０ａを、その内面部３１と外面部３２との間に開口縁部１０ａが挟み込まれるようにして設け、また、上記蓋体２０の枢着部を除く開口縁部２０ａにも、ゴム又は軟質合成樹脂で成型され、内面部３１と外面部３２とが略二つ折り状に連設された縁取体３０ｂを、その内面部３１と外面部３２との間に開口縁部２０ａが挟み込まれるようにして設け、上記両縁取体３０ａ、３０ｂの外面部３２、３２の先端には、先端側を該縁取体３０ａ、３０ｂの二つ折り部３４、３４側に折り返し、該二つ折り部３４、３４の外端面にまでは達しないように延設するカバー面部３３、３３を夫々連設し、両カバー面部３３、３３の間に、スライドファスナー４０のスライダーが通る間隙Ｓを形成し、該二つ折り部３４は前記カバー面部３３より低段面となるようにしてその上方にスライドファスナーの務歯部４２ａ、４２ｂが位置するようにし、上記カバン本体１０の縁取体３０ａの外面部３２とカバー面部３３との間には、スライドファスナー４０の一方側テープ部４１ａを差し込み、内面部３と開口縁部１０ａとの間には内張生地５０の端部と、前記カバン本体１９を奥側と開口部側とに仕切ると共に内蓋としての機能を有する仕切り生地５１の端部とを差し込み、前記カバー面部３３を捲り上げた状態でこの一方側テープ部４１ａと、外面部３２と、開口縁部１０ａと、内張生地５０と、仕切り生地５１と、内面部３１との重合部を縫い糸６０で縫合してこのカバー面部３３を元に戻し、上記蓋体２０の縁取体３０ｂの外面部３２とカバー面部３３との間には、スライドファスナー４０の他方側テープ部４１ｂを差し込み、内面部３１とカバン本体１０の開口縁部１０ａとの間には内張生地５０の端部を差し込み、前記カバー面部３３を捲り上げた状態でこの他方側テープ部４１ａと、外面部３２と、開口縁部２０ａと、内張生地５０と、内面部３１との重合部を縫い糸６０で縫合してこのカバー面部３３を元に戻し、上記縁取体３０ａの二つ折り部３４側の外端面には凹溝部３４ａを、縁取体３０ｂの二つ折り部３４側の外端面には、前記凹溝部３４ａ内に嵌り込む凸条部３４ｂを設け、さらに、前記仕切り生地５１には平面コの字状のファスナー開閉部５２を設けたことを特徴とする技術的手段を講じたものである。
【０００９】
それ故、本発明の合成樹脂製カバンは、スライドファスナー４０を閉じると、カバン本体１０と蓋体２０とを閉じ合わせることができ、該スライドファスナー４０を開くと、枢着辺を回転中心軸として該蓋体２０を開くことができるようにする作用を呈する。
【００１０】
また、上記縫い糸６０での縫合部は、テープ部４１ａあるいはテープ部４１ｂと、外面部３２と、開口縁部１０ａあるいは開口縁部１０ｂと、内張生地５０と、内面部３１との重なった部位であるので、工業用ミシンを使用して従来法で縫合できる作用を呈する。
【００１１】
そして本発明は、カバー面部３３を設けてあるので、上記縫合はこのカバー面部３３を、図３に破線で示すように捲り上げておいて縫合し、縫合後、このカバー面部３３を元に戻すと、該カバー面部３３で縫い糸６０での縫い目を覆い隠す作用を呈する。
【００１２】
【００１３】
本発明の合成樹脂製カバンは、上記作用に加えて、縁取体３０ａの二つ折り部３４側の外端面には凹溝部３４ａを、縁取体３０ｂの二つ折り部３４側の外端面には、前記凹溝部３４ａ内に嵌り込む凸条部３４ｂを設けたので、カバン本体１０と蓋体２０との開閉部の連結をスライドファスナー４０によって行うようにしても、このスライドファスナー４０の内側では縁取体３０ａ、３０ｂの二つ折り部３４側の外端面どうしが接触し、凹溝部３４ａ内に凸条部３４ｂが嵌り込むのでカバン内の密閉性が確実に保たれ、雨水の浸入等を防止する作用を呈する。
【００１４】
【００１５】
それ故、本発明の合成樹脂製カバンは、上記作用にさらに加え、内面部３１と開口縁部１０ａとの間には、内張生地５０の端部と仕切り生地５１の端部とを差し込み、この一方側テープ部４１ａと、外面部３２と、開口縁部１０ａと、内張生地５０と、仕切り生地５１と、内面部３１との重合部を縫い糸６０で縫合してなるので、該仕切り生地５１を、作業性があまり複雑化することなく、同時に取り付けられる作用を呈するものである。
【００１６】
【実施例】
次に、本発明の第１実施例を添付図面を参照して詳細に説明する。図1乃至図3の実施例は、キャスターバッグでの実施例で、図には現れていないが、図1の下部の奥側に車輪が取り付けられ、伸縮可能な引き手ハンドル１０１を握持して該車輪を転動させて引くことができるようにし、かつ提手１０２、１０３のいずれか一方を握持し、手に提げて使用することもできるようにしたものである。なお、本発明は、その他の、例えば、リュックサック式のもの、手提げカバン方式のもの、ポシェットのように肩等に掛ける方式のもの、ウエストポーチのように使用者の体に括りつけるもの等、あらゆる方式のものであっても無論差し支え無いものである。
【００１７】
図中、１０がカバン本体、２０が蓋体である。このカバン本体１０と蓋体２０とは、合成樹脂（本実施例では、ポリカーボネート）で一体成型され、従来と同様に箱状（シェル状ともいう。）に構成され、両者の開口縁部１０ａ、２０ａの一辺１１、２１どうしを枢着（ヒンジ連結）してなるのは従来と同じである。なお、一般的には、カバン本体１０が蓋体２０よりその深さを深く構成されるが、この深さの相違は特に問題とするものではなく、いずれか一方を深くしたり、同じ深さとしてもよい。なお、カバン本体１０と蓋体２０とは、あまりに硬質な合成樹脂を使用すると、後記する縫い糸６０による縫合が不可能となる場合があるので、工業用ミシンの針が貫通できる合成樹脂材を使用するのは無論である。
【００１８】
なお、開口縁部１０ａ、２０ａの一辺１１、２１どうしを枢着するには、通常、図示されていない蝶番が使用されるが、必ずしも蝶番を使用する必要性はなく、所定幅の可曲性生地材の一辺側を開口縁部１０ａの一辺の縁に沿って、他辺側を開口縁部２０ａの一辺の縁に沿って縫着等で連結しても差し支えないものである。
【００１９】
本発明は、上記カバン本体１０の枢着部を除く開口縁部１０ａに、ゴム又は軟質合成樹脂で成型され、内面部３１と外面部３２とが略二つ折り状に連設された縁取体３０ａを、その内面部３１と外面部３２との間に開口縁部１０ａが挟み込まれるようにして設けてある。この縁取体３０ａは、同一断面形状で長尺のものが用意され、適宜寸法に切断して使用すればよい。そして、該縁取体３０ａの断面形状は図３に示されるように、内面部３１と外面部３２とが略二つ折り状に連設された形状とし、さらに、この縁取体３０ａには、後に説明するカバー面部３３が連設され、二つ折り部３４の先端外面には凹溝部３４ａが設けられているが、この凹溝部３４ａも後に説明することとする。
【００２０】
なお、上記縁取体３０ａは、枢着部を除く開口縁部１０ａに設けるとしたが、これは開口部１０ａの枢着辺部位に取り付けを禁止するものではなく、枢着等に支障とならなければ、開口縁部１０ａの全周に渡って設けてもよい。なお、図示実施例では、縁取体３０ａと後記する縁取体３０ｂとは、開口縁部１０ａ、２０ａの三辺と枢着（ヒンジ連結）する一辺１１、２１の中央部を除く両側に渡って設けられ、該一辺１１、２１の中央部（図２のヒンジ部内側覆い生地１３で隠れた部位)は、この縁取体３０ａ、３０ｂが省略されている。
【００２１】
また、上記蓋体２０の枢着部を除く開口縁部２０ａにも、ゴム又は軟質合成樹脂で成型され、内面部３１と外面部３２とが略二つ折り状に連設された縁取体３０ｂを、その内面部３１と外面部３２との間に開口縁部２０ａが挟み込まれるようにして設けてある。この縁取体３０ｂは前記した縁取体３０ａと略同一のものを同様にして配設すればよい。なお、図示例では、この縁取体３０ｂの二つ折り部３４の先端外面に前記凹溝部３４ａ内に嵌り込む凸条部３４ｂを設けてあるが、この凹溝部３４ａと凸条部３４ｂとは、本発明では必須のものではなく、両者を省略することで、縁取体３０ａと縁取体３０ｂとは同一断面形状とすることができる。なお、図３において、縁取体３０ａと縁取体３０ｂとの双方の内面部３１、３１は厚みが異なるように表してあるが、これは、作図上の都合によるもので、後記する内張生地５０と、仕切り生地５１とは、図よりは極端に薄い生地で充分であるので、縁取体３０ａ、３０ｂの伸縮許容範囲内に収まるものであるから、該縁取体３０ａ、３０ｂは同一断面形状としても実用上差し支えないものである。
【００２２】
上記両縁取体３０ａ、３０ｂの外面部３２の先端には、先端側を該縁取体３０の二つ折り部側に折り返して延設するカバー面部３３を夫々連設してある。すなわち、縁取体３０ａ、３０ｂは、内面部３１と外面部３２とカバー面部３３とで、断面略Z字状に三つ折りされた形状に構成してなり、図３の右側の縁取体３０ａでさらに説明すると、内面部３１と外面部３２とは左側端の二つ折り部３４で連結され、外面部３２の先端（図右端）からはカバー面部３３が、二つ折り部３４側に向けて折り返されている。なお、カバー面部３３の先端（図３左端）は、二つ折り部３４の外端面（図３左端面）にまでは達しないように構成し、カバン本体１０と蓋体２０と併せた際（両縁取体３０ａ、３０ｂの二つ折り部３４、３４の外面端部どうしが接触した際）に、両縁取体３０ａ、３０ｂのカバー面部３３、３３間に、後記するスライドファスナー４０の、図では省略したスライダーが通る間隙Ｓ（図３参照）が確保されるようにしてある。また、同図３に最も明らかに示すように、両縁取体３０ａ、３０ｂの二つ折り部３４は、カバー面部３３より低段面となるようにし、その上方にスライドファスナー４０の務歯部４２ａ、４２ｂが位置するようにすると、上記スライダーの移動に支障とならないものである。
【００２３】
上記両カバン本体１０の縁取体３０ａの、外面部３２とカバー面部３３との間には、スライドファスナー４０の一方側テープ部４１ａを差し込み、内面部３１と開口縁部１０ａとの間には内張生地５０の端部を差し込み、この一方側テープ部４１ａと、外面部３２と、開口縁部１０ａと、内張生地５０と、内面部３１との重合部を縫い糸６０で縫合してある。スライドファスナー４０の一方側テープ部４１ａを外面部３２とカバー面部３３との間に差し込んだ際、この一方側テープ部４１ａの務歯部４２ａは、無論、上記カバー面部３３の外方に突出するようにしてある。なお、該スライドファスナー４０の務歯部４２ａは、通常、上記縁取体３０ａの二つ折り部側端よりもさらにその外側に突出するようにしてあるが、図３に示すように、該務歯部４２ａの下方に該縁取体３０ａの二つ折り部３４側が位置しているようにしてもよい。この様に設定すると、スライドファスナー４０を閉じた際、両縁取体３０ａ、３０ｂの両二つ折り部３４、３４の先端（該端面）が、このスライドファスナー４０の下方（カバン本体１０からみて内側）で密着し、密閉性を確実にすることができる。
【００２４】
上記スライドファスナー４０の一方側テープ部４１ａは、開口縁部１０ａに縫着固定されることになるが、一方側テープ部４１ａと、外面部３２と、開口縁部１０ａと、内張生地５０と、内面部３１との重合部を縫い糸６０で縫合し、上記カバー面部３３のみは縫合しないようにしてある。すなわち、このカバー面部３３は縫合の対象外とされるもので、縫合時は図３に破線で示すように捲りあげて、一方側テープ部４１ａと、外面部３２と、開口縁部１０ａと、内張生地５０と、内面部３１との重合部を縫い糸６０で縫合し、これらの縫合が終了したら、該カバー面部３３を元の状態に戻せばよいものである。
【００２５】
そして、上記両蓋体２０の縁取体３０ｂの外面部３２とカバー面部３３との間には、スライドファスナー４０の他方側テープ部４１ｂを差し込み、内面部３１とカバン本体１０又は開口縁部１０ａとの間には内張生地５０の端部を差し込み、この他方側テープ部４１ａと、外面部３２と、開口縁部２０ａと、内張生地５０と、内面部３１との重合部を縫い糸６０で縫合してある。この蓋体２０側の、他方側テープ部４１ａと、外面部３２と、開口縁部２０ａと、内張生地５０と、内面部３１との縫合は、前記した鞄本体１０側と同じように行えばよい。
【００２６】
次に、第２実施例の発明について説明する。本発明は、合成樹脂材で成型した箱状のカバン本体１０と、同じく合成樹脂材で成型した箱状の蓋体２０とを、両者の開口縁部１０ａ、２０ａの一辺１１、２１どうしを枢着してなる合成樹脂製カバンにおいて、上記カバン本体１０の枢着部を除く開口縁部１０ａに、ゴム又は軟質合成樹脂で成型され、内面部３１と外面部３２とが略二つ折り状に連設された縁取体３０ａを、その内面部３１と外面部３２との間に開口縁部１０ａが挟み込まれるようにして設けてある。また、上記蓋体２０の枢着部を除く開口縁部２０ａにも、ゴム又は軟質合成樹脂で成型され、内面部３１と外面部３２とが略二つ折り状に連設された縁取体３０ｂを、その内面部３１と外面部３２との間に開口縁部２０ａが挟み込まれるようにして設けてある。そして、上記両縁取体３０ａ、３０ｂの外面部３２の先端には、先端側を該縁取体３０ａ、３０ｂの二つ折り部３４側に折り返して延設するカバー面部３３を夫々連設し、上記カバン本体１０の縁取体３０ａの外面部３２とカバー面部３３との問には、スライドファスナー４０の一方側テープ部４１ａを差し込み、内面部３１と開口縁部１０ａとの間には内張生地５０の端部を差し込み、一方側テープ部４１ａと、外面部３２と、開口縁部１０ａと、内張生地５０と、内面部３１との重合部を縫い糸６０で縫合し、上記蓋体２０の縁取体３０ｂの、外面部３２とカバー面部３３との間には、スライドファスナー４０の他方側テープ部４１ｂを差し込み、内面部３１とカバン本体１０の開口縁部１０ａとの間には内張生地５０の端部を差し込み、他方側テープ部４１ａと、外面部３２と、開口縁部２０ａと、内張生地５０と、内面部３１との重合部を縫い糸６０で縫合してあるのは第１実施例の構成と同じである。
【００２７】
本発明は、上記縁取体３０ａの二つ折り部３４側の外端面には凹溝部３４ａを、縁取体３０ｂの二つ折り部３４側の外端面には、前記凹溝部３４ａ内に嵌り込む凸条部３４ｂを設けてある。この凹溝部３４ａと凸条部３４ｂとは相互に嵌り込んでカバン内の密閉性を確保するもので、スライドファスナー４０を閉じることで、凹溝部３４ａと凸条部３４ｂとは圧接するようにしてあり、スライドファスナー４０の務歯部４２ａ、４２ｂと、その下方に位置する縁取体３０ａ、３０ｂの二つ折り部３４、３４側外端面の位置関係を、該スライドファスナー４０を閉じた際、両縁取体３０ａ、３０ｂの両二つ折り部３４、３４の先端面部（外側端面）が、このスライドファスナー４０の下方で密着し、密閉性を確実にすることができるようにすればよい。なお、最近はスライドファスナーの気密性が高まっているが、この密閉性の確保は、雨水がカバンの中に入り込んで収納物をぬらすことを防ぐのを主たる目的とする。また、外力が加わって、カバン本体１０と蓋体２０とが衝突して音を立てることが想定できるが、両縁取体３０ａ、３０ｂはこのような場合の緩衝材として機能し、音が出ずらくするものである。
【００２８】
次に、第３実施例について説明する。本発明は、合成樹脂材で成型した箱状のカバン本体１０と、同じく合成樹脂材で成型した箱状の蓋体２０とを、両者の開口縁部１０ａ、２０ａの一辺１１、２１どうしを枢着してなる合成樹脂製カバンにおいて、上記カバン本体１０の枢着部を除く開口縁部１０ａに、ゴム又は軟質合成樹脂で成型され、内面部３１と外面部３２とが略二つ折り状に連設された縁取体３０ａを、その内面部３１と外面部３２との間に開口縁部１０ａが挟み込まれるようにして設け、また、上記蓋体２０の枢着部を除く開口縁部２０ａにも、ゴム又は軟質合成樹脂で成型され、内面部３１と外面部３２とが略二つ折り状に連設された縁取体３０ｂを、その内面部３１と外面部３２との間に開口縁部２０ａが挟み込まれるようにして設け、上記両縁取体３０ａ、３０ｂの外面部３２の先端には、先端側を該縁取体３０ａ、３０ｂの二つ折り部３４側に折り返して延設するカバー面部３３を夫々連設してあるのは、第１実施例及び第２実施例の構成と同じである。
【００２９】
本発明は、上記カバン本体１０の縁取体３０ａの、外面部３２とカバー面部３３との間には、スライドファスナー４０の一方側テープ部４１ａを差し込み、内面部３１と開口縁部１０ａとの間には、内張生地５０の端部と仕切り生地５１の端部とを差し込み、この一方側テープ部４１ａと、外面部３２と、開口縁部１０ａと、内張生地５０と、仕切り生地５１と、内面部３１との重合部を縫い糸６０で縫合してある。すなわち、本発明では、第２実施例の構成に加え、仕切り生地５１を設けてなり、この仕切り生地５１の端部を、縁取体３０ａの内面部３１と開口縁部１０ａとの間に共に差し込んで縫着してある。なお、この仕切り生地５１はその全周、すなわち４辺を開口縁部１０ａの内面部位に固定するもので、開口縁部１０ａの枢着部に縁取体３０ａを省略する場合は、別途、縫合や鋲着等でその端部を開口縁部１０ａに固定するものである。
【００３０】
上記仕切り生地５１は、カバン本体１０を仕切って使用するためのものであり、図２に示すように、カバン本体１０を奥側と開口側とに仕切るようにしてある。なお、この仕切り生地５１は内蓋としての機能もあり、蓋体２０を上から被せるようにして閉じる際に収納物が落ちないようにする使用目的にも対応できる。従って、この仕切り生地５１は、カバン本体１０側に代え、またはカバン本体１０側と共に、蓋体２０側に設けてもよい。
【００３１】
上記蓋体２０の縁取体３０ｂの外面部３２とカバー面部３３との間には、スライドファスナー４０の他方側テープ部４１ｂを差し込み、内面部３１とカバン本体１０又は開口縁部１０ａとの間には内張生地５０の端部を差し込み、この他方側テープ部４１ａと、外面部３２と、開口縁部２０ａと、内張生地５０と、内面部３１との重合部を縫い糸６０で縫合し、上記縁取体３０ａの二つ折り部３４側の外端面には凹溝部３４ａを、縁取体３０ｂの二つ折り部３４側の外端面には、前記凹溝部３４ａ内に嵌り込む凸条部３４ｂを設けてあるのは第２実施例と同じ構成である。
【００３２】
そして、本発明は、前記仕切り生地５１には平面コの字状のファスナー開閉部５２を設けてある。該仕切り生地５１はその周縁全周をカバン本体１０の開口縁部１０ａに沿わせて固定してあるので、そのままでは仕切として機能しないので開口部を設ける必要性がある。そして、この開口部は大きな収納物の出し入れが容易なように、三方ファスーナー方式と称されている、仕切り生地５１に平面コの字状のファスナー開閉部５２を設けたものである。
【００３３】
【発明の効果】
本発明は、カバン本体１０と蓋体２０との着脱可能な係止を、スライドファスナー４０にしたため、従来の錠止装置のような重たい係止金具の使用が回避でき、軽量な合成樹脂製カバンを提供できるものである。
【００３４】
そして、このスライドファスナー４０を、カバン本体１０と蓋体２０との開口縁部１０ａ、２０ａに縫着するようにしたので、従来金属で製造されていた中央メインフレーム７１及び中央サブフレーム７２及びカバー帯７３、７３も省略でき、部品点数を少なくすることができ、製造が容易で軽量な合成樹脂製カバンを提供できるものである。
【００３５】
また、本発明によれば、縁取体３０ａ、３０ｂにカバー面部３３を設けたので、前記縫合のミシン目を、このカバー面部３３で覆い隠すことができ、体裁のよい合成樹脂製カバンを提供できるものである。
【００３６】
また、本発明では、縁取体３０ａの折曲端部外面側には凹溝部３４ａを、縁取体３０ｂの折曲端部外面側には、前記凹溝部３４ａ内に嵌り込む凸条部３４ｂを設け、蓋体２０を閉じると、噛合して閉じたスライドファスナーの下方（内側）でこの凹溝部３４ａと凸条部３４ｂとが密接して、雨水が浸入しない合成樹脂製カバンを提供できるものである。なお、前記カバー面部３３は縫い目を覆い雨水の浸入を防ぐものである。
【００３７】
さらにまた、本発明は、仕切り生地５１の端部を、縁取体３０ａの内面部３１と開口縁部１０ａとの間に共に差し込んで縫着しているので、この仕切り生地５１の取り付けに特別な手数を要さず、容易に仕切り生地５１を取付けられる合成樹脂製カバンを提供できるものである。

And recently, this kind of synthetic resin bag has been applied to rucksacks, handbags, and relatively small bags such as pochettes and waist pouches.
[0003]
A typical conventional example of this type of synthetic resin bag will be described with reference to FIG. 4. First, a central main frame 71 made of a metal frame, a central subframe 72 also made of a metal frame, and a synthetic resin. The bag main body 10 is integrally formed and the lid 20 is made of the same material. The central main frame 71 is formed on the opening edge 10a of the bag main body 10 with a flange 74 as shown in FIG. A central sub-frame 72 is attached to the lid 20 with a collar 74, and the outer surface side of the central main frame 71 and the central sub-frame 72 (in FIG. 5, the lower side of the figure is the outer surface side of the bag). .) Is covered with cover bands 73, 73 covering the garment.
[0004]
The bag body 10 and the lid body 20 are pivotally attached at one side (left rear side portion in FIG. 4) with a hinge or the like not shown, and the bag body 10 and the lid body 20 and the openings of both are combined. Thus, the lid 20 is closed to the bag body 10. Engagement hook piece 75 (refer to FIG. 5) is detachably locked to the side opposite to the pivoted side, and engagement hook piece 75 (see FIG. 5) is attached to central subframe 72 side. An engaging / removing mechanism portion 76 is provided.
[0005]
That is, this conventional synthetic resin bag has a central main frame 71 and a central sub-frame 72 having predetermined strength, an engagement hook piece 75 and an engagement / disengagement mechanism portion 76 that detachably engages both of them. Is required. Furthermore, there is a problem in that the cover bands 73 and 73 are necessary for appearance, and the whole is heavy with these parts. In order to solve this problem, various proposals for improving the central main frame 71 and the central subframe 72 have been made. For example, in Patent Document 1, the central subframe 72 is omitted, and the central mainframe is replaced with a central mainframe. It has been proposed that it is molded with an assembly-type synthetic resin material, and that the central main frame is provided with reinforcing ribs over the entire circumference, so that the toughness can be reduced without reducing the toughness.
[0006]
It is easy to understand that the central plastic main frame is strong enough and can be reduced in weight, and is a welcome proposal for large synthetic resin bags such as suitcases. For relatively small bags such as bags, there is still a demand for weight reduction. The most important point of weight reduction in these conventional examples is the necessity to use many metal parts. It is assumed that the engagement / desorption mechanism 76 shown in FIG.
[0007]
[Problems to be solved by the invention]
Accordingly, the present invention has been made in view of the above problems, and provides a synthetic resin bag in which a central frame is omitted for weight reduction, and the engagement / disassembly mechanism portion is replaced with a slide fastener that is easy to reduce weight. This is an issue.
