【発明の属する技術分野】
この発明は、ランドセル、リュックサック等の背負い鞄の肩掛けベルト上端取付具に関するものである。
【０００２】
【従来の技術】
従来、この種の背負い鞄の肩掛けベルト上端取付具には、図４、５に示したように、取付環３、３を取り付けた連結板４、４の対向側面に歯部４ａ，４ａを設け、これら歯部４ａ，４ａを互いに噛み合わせて連結板４、４を、背負い鞄５の背当て部５ａに回動自在に取り付けることにより、前記取付環３、３を揺動自在とすると共に、前記連結板４、４に内方向の弾力を付したものが存在する。前記連結板４、４に内方向の弾力を付すには、連結板４の外側面４ｂを内方向に押し付ける一組のバネ３０、３０を設けたものとしている。
【０００３】
さらに、前記肩掛けベルト上端取付具は、上被覆板６ａの両側端上部に設けられたリベット孔３１ａ、３１ａおよび上端中央部に設けられたリベット孔３２ａから、下被覆板６ｂの両側端上部に設けられたリベット孔３１ｂ、３１ｂおよび上端中央部に設けられたリベット孔３２ｂにそれぞれリベット３３、３３、３３を貫通させて、背負い鞄５の背当て部５ａの裏側に取り付けられる止板３４にリベット止めしている。
【０００４】
このように構成された背負い鞄の肩掛けベルト上端取付具は、肩掛けベルト１の取付環３、３への取り付け位置を、連結板４、４の回動角度に応じた取付環３、３の揺動幅内において、使用者の体格に応じて左右方向に移動することができると共に、連結板４、４に付される内方向に弾力によって取付環３、３を使用者の体格に応じた状態に維持しておくことができるので、非常に使用し易く、使用者に圧迫感や疲労感を与えないものとなるという作用効果を有していた。
【０００５】
【発明が解決しようとする課題】
ところで、背負い鞄の肩掛けベルト上端取付具において、肩掛けベルト１の取付環３、３への取り付け位置を使用者の体格に応じて具合良く左右方向に移動したり、取付環３、３を使用者の体格に応じた状態に維持しておくには、連結板４、４に内方向の弾力を付すためのバネ３０、３０に充分な弾力を必要とする。
【０００６】
しかしながら、従来の背負い鞄の肩掛けベルト上端取付具では、連結板４、４に内方向の弾力を付すためのバネ３０、３０を、連結板４の外側面４ｂの側方に一組のみ設けたものとしているため、充分な弾力を持たせるには、バネ３０、３０自体が大きくなってしまい、そのため肩掛けベルト上端取付具が大きくなり、背負い鞄に取り付けるには嵩が高いものになるという課題を有していた。
【０００７】
また、従来の背負い鞄の肩掛けベルト上端取付具では、前記バネ３０を連結板４の外側面４ｂの側方に一組のみ設けたものとしているため、連結板４の回動をスムーズに行えず、そのため取付環３、３の揺動もスムーズに行えないことがあり、使用感が悪いという課題を有していた。
【０００８】
そこで、この発明は、上記従来の課題を解決するものであり、使用するバネを小さくしても、充分な弾力をもたすことができる構造として、肩掛けベルト上端取付具を小さくし、背負い鞄に取り付けても嵩が高いものにはならず、また取付環の揺動もスムーズに行えるようにして、使用感を良くした背負い鞄の肩掛けベルト上端取付具を提供することを目的としてなされたものである。
【０００９】
【課題を解決するための手段】
そのため、この発明の背負い鞄の肩掛けベルト上端取付具は、取付環３、３を上部に取り付けた連結板４、４を背負い鞄５の背当て部５ａに回動自在に取り付けることにより、前記取付環３、３を揺動自在とし、前記連結板４、４を内方向に押し付ける一組のバネ１１、１１を連結板４、４の外側面４ｂ、４ｂの側方に取り付けると共に、前記連結板４、４を内方向に押し付けるもう一組のバネ１２、１２を連結板４、４の内部に設けたバネ挿入孔７、７に取り付けたものとして、これら連結板４、４に内方向の弾力を前記二組のバネ１１、１１、１２、１２により付したものとしている。
【００１０】
さらに、この発明の背負い鞄の肩掛けベルト上端取付具は、取付環３、３を上部に取り付けた連結板４、４の対向側面に歯部４ａ、４ａを設け、これら歯部４ａ、４ａを互いに噛み合わせて連結板４、４を背負い鞄５の背当て部５ａに回動自在に取り付けることにより、前記取付環３、３を揺動自在とし、前記連結板４、４を内方向に押し付ける一組のバネ１１、１１を連結板４、４の外側面４ｂ、４ｂの側方に取り付けると共に、前記連結板４、４を内方向に押し付けるもう一組のバネ１２、１２を連結板４、４の内部に設けたバネ挿入孔７、７に取り付けたものとして、これら連結板４、４に内方向の弾力を前記二組のバネ１１、１１、１２、１２により付したものとすることができる。
