Description

【0001】
【発明の属する技術分野】
この発明は、ランドセル本体の肩掛けベルトおよびその取付具を改良したランドセルに関するものである。
【0002】
【従来の技術】
従来のランドセルの取付具としては、図9に示したように、金属板を二つ折りにした連結体31の折り曲げ部の略中央部を分断して二つの挿通部32、32を設け、それぞれの挿通部32、32の下方に止め孔33、33を設けると共に、前記挿通部32、32の互いに向き合う端部側に形成される空間部34に略Ω形状の吊下環35の脚部を回動自在に取り付け、さらにこれら挿通部32、32の両端にそれぞれ略三角形状の連結環37、37を回動自在に取り付けたものが存在する。
【0003】
このように構成されたランドセルの取付具は、図10に示したように、ランドセル本体41の背当て部42の最上端または最上端から少し下げた位置に連結体31を取り付け、連結環37、37にそれぞれ肩掛けベルト43、43の上端を取り付けていた。
【0004】
前記肩掛けベルト43は、厚手の皮革や合成樹脂地等からなる上層体と、発泡合成樹脂体に薄手の皮革や合成樹脂地等を巻き付けてなる下層体より構成され、これらを重ね合わせて両側部を縫着したものとしている。
【0005】
【発明が解決しようとする課題】
しかしながら、上記従来のランドセルでは、図11に示したように、連結体31の挿通部32、32の両端に取り付けられた連結環37、37が使用者の背中方向に回動し、連結環37、37に取り付けた肩掛けベルト43、43が、使用中にランドセルの重量により次第に肩からずれて、使用者の背中から離れて後方へ傾いてしまう。そのため、ランドセルの重心が使用者の背中から離れ、ランドセルが背負い難くなると共に重く感じるという課題を有していた。
【0006】
さらに、上記従来のランドセルでは、肩掛けベルト43が上記したような構成であるため、張りがなく柔らかいので、使用中に使用者の肩からずれ易くなり、ランドセルが背負い難くなると共に重く感じるという上記課題を助長することになっていた。
【0007】
また、上記従来のランドセルでは、使用者の背中から離れて後方へ傾いてしまうため、ランドセル本体41の背当て部42の下端部が使用者の背中に当たって、使用者が痛みを感じたりし、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、肩掛けベルトが使用中にランドセルの重量により肩からずれず、ランドセルの背当て部が使用者の背中に密着して、ランドセルの重心が使用者の背中から離れず、重く感じることがなく、しかも使用感が良いランドセル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】
この発明のランドセルは、ランドセル本体2の背当て部3の上部に設けた取付具4の左右一対の連結体5の上端にそれぞれ弾性部材6を上方向に延設し、これら弾性部材6に肩掛けベルト1を取り付けたものとしている。
【0010】
さらに、この発明のランドセルは、ランドセル本体2の背当て部3の上部に設けた取付具4の左右一対の連結体5の上端にそれぞれ弾性合成樹脂板よりなる弾性部材6を上方向に一体成形することにより延設し、これら弾性部材6に沿わせて肩掛けベルト1をそれぞれ取り付けたものとしている。
【0011】
そして、この発明のランドセルは、前記肩掛けベルト1の上端部を、取付具4に設けた挿通部7に取り付けた連結環8に巻着すると共に、弾性部材6に固着したものとしている。
【0012】
さらに、この発明のランドセルは、前記連結体5を背当て部3にそれぞれ左右方向に揺動自在に取り付けると共に、連結体5にそれぞれ内方向の弾力を付したものとしている。
【0013】
【発明の実施の形態】
以下、この発明のランドセルの実施の形態を、図面に基づいて詳細に説明する。
【0014】
図1は、この発明のランドセルを背当て部側から見た部分拡大図を示している。1は左右一対の肩掛けベルトであり、これら肩掛けベルト1の上端部は、ランドセル本体2の背当て部3の上部に設けた取付具4に取り付けられている。また、肩掛けベルト1の下端部は、ランドセル本体2の底部に設けた取付具(図示せず)に取り付けられている。なお、背当て部3の上部とは、背当て部3の最上端または最上端から少し下げた位置のことをいう。
【0015】
前記肩掛けベルト1は、図2に示したように、厚手の皮革や合成樹脂地等からなる上層体1aと、発泡合成樹脂体に薄手の皮革や合成樹脂地等を巻き付けてなる下層体1bより構成され、これら上層体1aと下層体1bを重ね合わせて、その両側部を縫着したものとしている。
【0016】
前記取付具4は、図3、4に示したように、左右一対の連結体5の上端にそれぞれ弾性合成樹脂板よりなる弾性部材6を上方向に一体成形することにより延設したものとし、それぞれの連結体5と弾性部材6の間には挿通部7を設け、これら挿通部7の両端にはそれぞれ略三角形状の連結環8を上下方向に回動自在に取り付けたものとしている。そして、前記連結体5の上端にそれぞれ延設した弾性部材6に沿わせて肩掛けベルト1をそれぞれ取り付けたものとしている。なお、弾性部材6としては、前記弾性合成樹脂板の他に、図5、6に示したような弾性金属板や弾性線材などとすることができる。
【0017】
そこで、弾性部材6に沿わせて肩掛けベルト1を取り付けるには、前記取付具4の挿通部7に上下方向に回動自在に取り付けた連結環8に、この連結環8を上方向に回動した状態にして、肩掛けベルト1の上端部を巻着すると共に、その上端部を弾性部材6に固着したものとしている。前記肩掛けベルト1の上端部を弾性部材6に固着するには、肩掛けベルト1の上端部を弾性部材6に重ね合わせ、肩掛けベルト1の上端部に設けたリベット孔9と、弾性部材6に設けたリベット孔10を合致させて、両リベット孔9、10にリベット11を通して、リベット止めすると共に、必要に応じて、肩掛けベルト1と弾性部材6の両側部どうしを縫着したものとしている。
【0018】
なお、弾性部材6に沿わせて肩掛けベルト1を取り付けるには、前記したような連結環8を用いた構造によると非常に堅固なものになるが、このような構造に限定されることはない。また、前記した構造では、弾性部材6に肩掛けベルト1の表面側を沿わせたものとしているが、弾性部材6に肩掛けベルト1の裏面側を沿わせたものとしてもよく、さらに肩掛けベルト1の上層体1aと下層体1bの間に弾性部材6を挟み込んで、弾性部材6に肩掛けベルト1を沿わせたものとしてもよい。
【0019】
前記弾性部材6は、使用者が肩掛けベルト1を肩に掛けたときに肩に沿って曲がり得る長さとすればよく、図示したものでは約5cm程度としているが、必要に応じてこれより長くしても短くしてもよい。また、弾性部材6は、連結体5の上方向に設けておれば特にその角度は限定されるものではなく、真上としてもよいがランドセル本体2の背当て部3側から肩掛けベルト1側に若干傾けたものとしてもよい。
【0020】
さらに、前記取付具4は、左右一対の連結体5を背当て部3にそれぞれ左右方向に揺動自在に取り付けると共に、連結体5にそれぞれ内方向の弾力を付したものとしている。図に示した実施の形態では、前記連結体5を背当て部3に左右方向に揺動自在に取り付けるには、連結体5を上下被覆板12a、12bの間に挟み込み、連結体5の下端に設けた軸孔13に下被覆板12bに設けた止体14を軸支している。さらに、前記連結体5に内方向の弾力を付すには、それぞれの連結体5の外側面5aを内方向に押し付けるバネ15を上下被覆板12a、12bの間に取り付けている。このバネ15は、略U字状としており、外体15aは下被覆板12bに設けた支持部16および支持体17に支持され、内体15bは連結体5の外側面5aに当接するようにしている。なお、18は上被覆板12aの上に当生地19(図1参照)を押さえ付けておくための押板である。20は不使用時にランドセルを吊り下げておくための吊下環であり、下被覆板12bの上端中央部に取り付けられている。
【0021】
そして、前記取付具4は、押板18に設けられたリベット孔21から上被覆板12aに設けられたリベット孔22にリベット23を貫通させ、さらにこのリベット23を下被覆板12bに設けられたリベット孔24を貫通させて、ランドセル本体2の背当て部3の裏側に取り付けられる止板(図示せず)にリベット止めしている。
【0022】
以上のように構成したこの発明のランドセルは、図1、7に示したように、取付具4の連結体5の上端に延設した弾性部材6に取り付けられた肩掛けベルト1の取付部がランドセル本体2から上方に向いた状態となっている。そのため、使用者がランドセルを背負った場合には、図8に示したように、ランドセル本体2が常に斜め上方に引っ張られた状態となる。しかも、肩掛けベルト1の上端部は弾性部材6に取り付けているので、肩掛けベルト1が使用者の肩に沿うように曲がる。
【0023】
したがって、このような状態で、この発明のランドセルを背負うと、ランドセル本体2の背当て部3が使用者の背中に密着した状態に保たれることになる。
【0024】
さらに、この発明のランドセルは、ランドセル本体2の背当て部3の上部での肩掛けベルト1の位置を、連結体5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、連結体5に付される内方向の弾力によって、その体格に応じた位置に維持しておける。
【0025】
したがって、この発明のランドセルは、肩掛けベルト1の位置を使用者の体格に応じたものとすることができると共に、使用者の肩に密着させた状態にしておくことができる。
【0026】
【発明の効果】
この発明のランドセルは、以上に述べたように構成されているので、肩掛けベルトが使用中にランドセルの重量により肩からずれず、ランドセルの背当て部が使用者の背中に密着して、ランドセルの重心が使用者の背中から離れず、重く感じることがなく、しかも使用感が良いものとなった。
