Description

【０００１】
【発明の属する技術分野】
本発明は、収納部材の脱着構造及び収納部材の脱着構造付き自転車に関するものである。
【０００２】
【従来の技術】
従来、自転車の荷台に対して取り付けた荷かご（収納部材）を、必要に応じて着脱自在にしたものが知られている（例えば特許文献１）。
この場合、荷かごを荷台へ固定する構造としては、荷かごの底部に係合片を設けると共に、荷台には、この係合片を嵌合可能な係合孔を設けておき、且つこの係合孔は、係合片を上から嵌合させた状態で前後方向へ移動させることができてこの移動後には係合片を上方へ移動させること（引き上げること）はできないようにしたものを採用している。
【０００３】
すなわち、自転車の荷台に対し、係合孔へ係合片を合致させるように留意しつつその上方から荷かごを載せた後、この荷かご自体を前後方向へ移動させることで、荷かごの係合片を荷台の係合孔へ係止させるというものであった。

【発明が解決しようとする課題】
荷かごを荷台へ固定するうえで係合片と係合孔とを位置合わせしようとする場合、その様子は荷かご自体が邪魔になって操作者には見えないため、非常に面倒で且つやりにくい（難しい）ということがあった。
また、係合片を係合孔へ係止させたり、反対にこの係止状態を解除させたりするうえで荷かご自体を前後に移動させる場合、荷かごに既に物品が入っていれば、当然に荷かごが重いという不具合があり、しかも荷かごが自転車の荷台上で高背になっていることも相まって、特に主婦などには非常に操作しにくいということがあった。
【０００６】
本発明は、上記問題点に鑑み、自転車等に対する荷かご等の収納部材の着脱が容易且つ軽快に行えるようにしたものである。
【０００７】

【発明の実施の形態】
以下、本発明を図示の実施の形態に従って説明する。
図１〜図１０は本発明の一実施の形態を示している。図１において、１は自転車で、左右一対のハンドル２、サドル３、後部荷台４、前部荷台５を有している。
図２〜図７において、後部荷台４は、自転車１のフレーム側に固定される後キャリヤ７を有している。後キャリヤ７は、長方形状に形成されたキャリヤ枠８と、キャリヤ枠８の後部を左右に連結する後連結杆９と、キャリヤ枠８の前部側を左右に連結する前連結杆１０と、キャリヤ枠８の左右中央部を前後に連結する連結板１１とを有している。キャリヤ枠８は、左右一対の側部杆８ａと、側部杆８ａの前端部同士を連結する前部杆８ｂと、側部杆８ａの後端部同士を連結する後部杆８ｃとを具備している。
【００１５】
後キャリヤ７の前端は左右一対の前支持杆１３を介して自転車１のサドル３下方のフレームに連結固定され、後キャリヤ７の後部は、左右一対の後支持杆１４を介して、自転車１の後ハブ等に連結固定されている。
後キャリヤ７により構成された後部荷台４に、荷かご（収納部材）１６が載置固定され、この載置固定した荷かご１６を、ロック部材１７により後部荷台４上から不測に外れないようにロックしている。
荷かご１６及びロック部材１７は、それぞれ合成樹脂又は金属等により構成されている。荷かご１６は、例えばスーパー等の店内に備え付けられている買い物かご又はかご部を有するカートに随伴可能な大きさとされている。また、図１に示すように、荷かご１６の上縁部寄りには、持ち運びに使用する一対の把持１８が上下揺動自在に設けられている。
【００１６】
荷かご１６の底部下面に、下方に突出した係合部２１が４個設けられ、これら係合部２１は荷かご１６の底部下面に前後左右に配置されている。各係合部２１は、左右一対の突出片２２と該一対の突出片２２の下端間を連結する連結片２３とを有し、コの字状に形成されている。また、各係合部２１は、前後幅及び左右幅が下方に向けて徐々に小さくなるように先細り状に形成されている。荷かご１６を後部荷台４に載置したとき、荷かご１６の各係合部２１が、後キャリヤ７のキャリヤ枠８と連結板１１と後連結杆９と前連結杆１０とで囲まれる左右一対の開口部２５に挿通されて、各係合部２１が後キャリヤ７上面より下方に突出するようになっている。このとき、前側の２個の係合部２１は、後キャリヤ７の前連結杆１０に後側から接当乃至近接し、後側の２個の係合部２１は、後キャリヤ７の後連結杆９に前側から接当乃至近接し、これにより、後部荷台４に載置した荷かご６の前後移動を規制するように、各係合部２１が後キャリヤ７に係合される。また、係合部２１は、キャリヤ枠８の側部杆８ａに左右方向内方から接当乃至近接し、これにより、後部荷台４に載置した荷かご６の左右移動を規制するように、各係合部２１が後キャリヤ７に係合される。
【００１７】
ロック部材１７は、係合部２１を後キャリヤ７上面より下方に突出した状態にロックするためのものであり、ロック部材１７は、後部荷台４の下面側を該下面に沿って前後移動するロック部材本体２７と、ロック部材本体２７の一端（後端）からから下方に屈曲された把持部３０とを備える。
ロック部材１７のロック部材本体２７が、スペーサ台３１を介して後キャリヤ７の連結板１１に下側から接当するように配置され、スペーサ台３１はロック部材本体２７の上面に固着され、ロック部材１７及びスペーサ台３１は、連結板１１の下面に前後一対のリベット３２により前後移動自在に保持されている。一対のリベット３２は連結板１１に下方突出状に取付られ、これらリベット３２にスペーサ台３１及びロック部材本体２７は前後方向の長孔２８，２９を介して前後方向に摺動自在に嵌合保持され、これにより、ロック部材１７が、後部荷台４に、図５及び図６に矢印で示すロック位置Ａとロック解除位置Ｂとに前後移動自在に支持されている。即ち、ロック部材１７の前方移動により、図５及び図６に実線で示す如くロック部材１７がロック位置Ａにセットされ、ロック部材１７の後方移動により、図５に鎖線で示す如くロック部材１７がロック解除位置Ｂにセットされることになる。
【００１８】
ロック部材１７のロック部材本体２７に、前記係合部２１に対応して４個のロック片３３が設けられ、ロック部材１７をロック位置Ａに移動したとき、各ロック片３３が、対応する係合部２１の連結片２３の上側であって一対の突出片２２間に位置するように嵌合して、係合部２１に係合し、また、ロック部材１７をロック解除位置Ｂに移動したとき、各ロック片３３が、対応する係合部２１の突出片２２間から後退して、係合部２１から外れるように構成されている。
ロック部材本体２７の後端部であって把持部３０の左右方向中央部に、操作用開口部３５が設けられ、ロック部材本体２７から、弾性突出片３６が操作用開口部３５に対応する位置に突設されている。弾性突出片３６の基部側に、上方に突出した係合片３８が設けられ、弾性突出片３６の先端側が、押圧操作部３９とされている。
【００１９】
連結板９の後端部下面には、下方突出した係止片４２が設けられ、係合片３８の前面側に傾斜面４５が形成されており、ロック部材１７をロック解除位置Ｂからロック位置Ａに前方移動したとき、係合片３８の傾斜面４５が係止片４２に接当摺動して、弾性突出片３６が下方に弾性変形することにより、係合片３８が係止片４２を後側から前側に乗り越えて、係合片３８が係止片４２に前側から係合し、これによりロック部材１７をロック位置Ａで後方移動を規制するようになっている。
【００２０】
従って、ロック部材１７をロック位置Ａに移動したとき、ロック部材１７がロック位置Ａからロック解除位置Ｂに移動不能となるように、ロック部材１７を後キャリヤ７（後部荷台４）に係脱自在に係合する係合機構４６が、係止片４２と係合片３８とにより構成されている。
図８〜図１０において、一対のハンドル２は、ヘッドパイプ４９の上方で支持体５０を介してＵ字状に連結され、この一対のハンドル２間に前部荷台５が配置されている。前部荷台５は、自転車１のフレーム側に固定される前キャリヤ５１（図８に示す）と、前キャリヤ５１の上面に固定される板状の補助台（台座）５２（図９に示す）とを有している。前キャリヤ５１は、止めねじ等の締結具５３により支持体５０上に締め付け固定されると共に、支持腕５５を介して止めねじ等の固定具５６によりハンドル２に連結固定されている。
【００２１】
補助台５２は前キャリヤ５１上に配置されて、取付金具５９を介して止めねじ等の締結具５８により前キャリヤ５１に締め付け固定されている。この前部荷台５にペットかご（収納部材）６１が載置固定されている。
ペット用かご６１側に図示省略の係合部が、前記荷かご１６におけるの係合部２１と同様に、下方突設され、補助台５２に、前部荷台５にペット用かご６１を載置したときペット用かご６１の係合部が上側から挿脱自在に挿通される挿通孔６２が設けられ、係合部を補助台５２の挿通孔６２に挿通した状態にロックするロック部材６３が設けられ、ロック部材６３は、前部荷台５に、係合部を補助台５２の挿通孔６２に挿通した状態にロックするロック位置とそのロックを解除するロック解除位置とに、前後移動自在に保持され、ロック部材６３は、ペット用かご６１の係合部に係脱自在に係合するロック片６４を有している。
【００２２】
上記実施の形態によれば、荷かご１６を自転車１の後部荷台４に取り付ける場合、まず、ロック部材１７をロック解除位置Ｂに移動しておき、この状態で、荷かご１６を後部荷台４に対して上側から降ろして、各係合部２１を後キャリヤ７の左右一対の開口部２５に挿通させると、各係合部２１が後キャリヤ７の後連結杆９及び前連結杆１０に係合して荷かご１６の前後移動が規制されると共に、各係合部２１が後キャリヤ７のキャリヤ枠８（側部杆８ａ）に係合して、荷かご１６の左右移動が規制される。
【００２３】
次に、ロック部材１７の把持部３０を把持してロック部材１７を前方に移動させると、ロック部材１７がロック解除位置Ｂからロック位置Ａに移動し、各ロック片３３が、対応する各係合部２１の連結片２３の上側であって一対の突出片２２間に嵌合するように突出し、係合部２１が後キャリヤ７に対して上方側に抜脱不能になる。このとき、係合機構４６の係合片３８が、係止片４２を後側から前側に乗り越えて、係合片３８が係止片４２に前側から係合し、これによりロック部材１７がロック位置Ａからロック解除位置Ｂに移動不能となり、ロック部材１７は、係合部２１を後キャリヤ７上面より下方に突出した状態にロックする。
【００２４】
従って、後部荷台４に荷かご１６を載せた後、ロック部材１７を移動操作するだけで荷かご１６を簡単かつ確実に固定ができ、荷かご１６が相当に重くても固定しずらいということもなくなる。
また、このロック状態では、荷かご１６の各係合部２１が後キャリヤ７の開口部２５に嵌合し、しかも、ロック部材１７の各ロック片３３が、対応する各係合部２１の突出片２２間に嵌合した状態になるため、後部荷台４（後キャリヤ７）に対して荷かご１６が前後及び左右にガタ付いたりするおそれなく確実かつ安定に載置固定される。
【００２５】
また、このとき、ロック部材１７の係合片３８が後キャリヤ７の係止片４２に前側から係合した状態になり、また、ロック部材１７の各ロック片３３が、対応する各係合部２１の突出片２２間に嵌合した状態になるため、ロック部材１７も後キャリヤ７に対してガタ付いたりしないように安定に固定される。
また、荷台４に収納部材１６を載置したときに、係合部２１がキャリヤ７上面より下方に突出するようにし、ロック部材１７により、係合部２１をキャリヤ７上面より下方に突出した状態にロックするようにしているので、上記の如く後キャリヤ７を、荷かご１６が前後及び左右に移動するのを規制するための規制部材として兼用することができるし、また、上記の如く後キャリヤ７を、ロック部材１７がガタ付かないように係合するための係合機構４６の一部として利用することができ、後キャリヤ７を有効に利用して、後部荷台４を極力薄くコンパクトに形成することが可能になる。
【００２６】
そして、自転車１の後部荷台４から荷かご１６を取り外すには、まず、操作部３９を下方に押圧操作して、係合片３８を係止片４２から外し、この状態で、ロック部材１７の把持部３０を持ってロック部材１７を後方に引き、ロック部材１７をロック位置Ａからロック解除位置Ｂに移動する。すると、ロック部材１７の各ロック片３３が係合していた係合部２１から外れ、各係合部２１が後キャリヤ７に対して上側に抜脱可能になるため、その後は、荷かご１６を後部荷台４に対して上方に持ち上げればよく、荷かご１６を自転車１から簡単に取り外して、持ち運ぶことができる。
【００２７】
図１１〜図１６は他の実施の形態を示し、後部荷台４の後キャリヤ７は、荷かご（収納部材）１６を載置可能な板状に形成されている。ロック部材１７のロック部材本体２７は、後キャリヤ７に下側から接当するように配置され、ロック部材１７は、後キャリヤ７の下面に前後一対のねじ軸６５により前後移動自在に保持されている。一対のねじ軸６５は後キャリヤ７の下面に下方突設され、これらねじ軸６５にロック部材本体２７は前後方向の長孔２９を介して前後方向に摺動自在に嵌合保持され、ねじ軸６５の下端部に螺合したナット６６により抜け止めされている。これにより、ロック部材１７が、後部荷台４に、図１４及び図１５に矢印で示すロック位置Ａとロック解除位置Ｂとに前後移動自在に支持されている。
【００２８】
また、板状の後キャリヤ７に、前後左右の４個の挿通孔６７が設けられている。これら挿通孔６７は各係合部２１に対応するように配置されており、後部荷台４に荷かご１６を載置した際に、各係合部２１が対応する各挿通孔６７に上側から挿脱自在に挿通（嵌合）するようになっている。後部荷台４に載置した荷かご１６の前後移動及び左右移動を規制するように、前記各係合部２１が後キャリヤ７の挿通孔６７の開口縁部に係合されている。また、係合機構４６の係止片４２は、板状の後キャリヤ７の後端部に設けた貫通孔の開口縁部により構成されている。その他の点は前記実施の形態の場合と同様の構成である。
【００２９】
図１７〜図２２は他の実施の形態を示し、後部荷台４は、後キャリヤ７の他に板状の補助台７１を有し、後キャリヤ７は、長方形状に形成されたキャリヤ枠８と、キャリヤ枠８の後部を左右に連結する後連結杆９と、キャリヤ枠８の前部側を左右に連結する前連結杆１０と、後連結杆９と前連結杆１０とを前後に連結する一対の前後杆７２とを有し、前後杆７２の後端同士は互いに連結され、前後杆７２の前端は一対の前支持杆１３にそれぞれに連結されており、一対の前後杆７２及び一対の前支持杆１３は、一体に形成されている。補助台７１の前端下面に係合突片７３が突設され、キャリヤ枠８に補助台７１が内嵌固定され、係合突片７３は、キャリヤ枠８に下側から係合されている。
【００３０】
ロック部材１７のロック部材本体２７は、補助台７１に下側から接当するように配置され、ロック部材１７は、補助台７１と、後キャリヤ７の後連結杆９及び前連結杆１０との間に、前後移動自在に保持されて、これにより、ロック部材１７が、後部荷台４に、図２０及び図２１に矢印で示すロック位置Ａとロック解除位置Ｂとに前後移動自在に支持されている。
また、補助台７１に、前後左右の４個の挿通孔６７が設けられている。これら挿通孔６７は各係合部２１に対応するように配置されており、後部荷台４に荷かご１６を載置した際に、各係合部２１が対応する各挿通孔６７に上側から挿脱自在に挿通（嵌合）するようになっている。後部荷台４に載置した荷かご１６の前後移動及び左右移動を規制するように、前記各係合部２１が補助台７１の挿通孔６７の開口縁部又はキャリヤ枠８に係合されている。また、係合機構４６の係止片４２は、補助台７１に設けた凹部の後縁部により構成されている。その他の点は前記実施の形態の場合と同様の構成である。
【００３１】
図２３〜図２８は他の実施の形態を示し、後部荷台４は、後キャリヤ７の他に板状の補助台７１を有し、後キャリヤ７は、前記図１７〜図２２の実施の形態の場合と同様にキャリヤ枠８と後連結杆９と前連結杆１０と一対の前後杆７２とを有している。補助台７１はロック部材１７と一体に構成され、補助台７１は、キャリヤ枠８に面一になるように内嵌状に配置されて、ロック部材１７と共に後キャリヤ７に対して前後摺動自在に保持されている。
ロック部材１７及び補助台７１にコの字状の支持部材７５が設けられている。支持部材７５は左右一対の係合爪７６を有し、この一対の係合爪７６をロック部材１７及び補助台５２に左右一対の取付孔７７を介して係合することにより、支持部材７５は、ロック部材１７及び補助台７１に下方突出状に固着され、キャリヤ７の一対の連結杆７２に前後摺動自在に外嵌され、これにより、ロック部材１７は補助台７１と共にロック位置Ａとロック解除位置Ｂとに前後移動自在に支持されている。
【００３２】
また、補助台７１に、前後左右の４個の挿通孔６７が設けられている。これら挿通孔６７は各係合部２１に対応するように配置されており、後部荷台４に荷かご１６を載置した際に、各係合部２１が対応する各挿通孔６７に上側から挿脱自在に挿通（嵌合）するようになっている。また、後部荷台４に載置した荷かご１６の左右移動を規制するように、各係合部２１が補助台７１の挿通孔６７の開口縁部に係合されている。各挿通孔６７は、各係合部２１に比べて前後方向に長く形成されており、補助台７１をロック部材１７と共に前側（ロック位置Ａ）に移動したとき、各係合部２１が各挿通孔６７の後側に位置（挿通）して、各ロック片３３が、対応する係合部２１に係合し、補助台７１をロック部材１７と共に後側（ロック解除位置Ｂ）に移動したとき、各係合部２１が各挿通孔６７の前側に位置（挿通）して、各ロック片３３が、係合部２１から外れるようにようになっている。
【００３３】
また、荷かご１６を後部荷台４に載置したとき、荷かご１６の各係合部２１が、後キャリヤ７のキャリヤ枠８と後連結杆９と前連結杆１０と前後杆７２とで囲まれる左右一対の開口部２５に挿通されて、各係合部２１が後キャリヤ７上面より下方に突出するようになっている。このとき、前側の２個の係合部２１は、後キャリヤ７の前連結杆１０に後側から接当乃至近接し、後側の２個の係合部２１は、後キャリヤ７の後連結杆９に前側から接当乃至近接し、これにより、後部荷台４に載置した荷かご６の前後移動を規制するように、各係合部２１が後キャリヤ７に係合される。また、係合機構４６の係止片４２を、キャリヤ枠８の前部杆８ｃで兼用している。その他の点は前記実施の形態の場合と同様の構成である。
【００３４】
図２９及び図３０は他の実施の形態を示し、後部荷台４は、後キャリヤ７と補助台７１とを有し、後キャリヤ７は、キャリヤ枠８と後連結杆９と前連結杆１０と一対の前後杆７２とを有し、キャリヤ枠８は、左右一対の側部杆８ａと前部杆８ｂとを有し、一対の側部杆８ａの後端間を連結する後部杆が省略されていて一対の側部杆８ａの後端側は開放状に形成されている。
補助台７１の左右両側部に、一端が開口した前後方向の嵌合孔８０が設けられ、補助台７１は、後キャリヤ７に対して、一対の側部杆７８に嵌合孔８０を介して外嵌するように前後方向に差し込んで、一対の止めねじ８１等により止められている。止めねじ８１は、補助台７１の後端部に下方突出状に螺合され、止めねじ８１の下方突出部が後連結杆９に前側から係合されて、補助台７１が後側に抜けないように抜け止めされている。荷かご１６側に係合部２１が下方突設され、補助台７１に、後部荷台４に荷かご１６を載置したとき係合部２１が上側から挿脱自在に挿通される挿通孔６７が設けられ、係合部２１を補助台７１の挿通孔６７に挿通した状態にロックするロック部材１７が設けられ、ロック部材１７は、後部荷台４に、係合部２１を補助台７１の挿通孔６７に挿通した状態にロックするロック位置Ａとそのロックを解除するロック解除位置Ｂとに、移動自在に保持されている。その他の点は前記実施の形態の場合と同様の構成であり、ロック部材１７は、係合部２１に係脱自在に係合するロック片３３を有している。
【００３５】
なお、荷かご１６を、スーパー等の店内に備えられている買い物かご又はかご部を有するカートに随伴可能な大きさとするうえで、スーパーなどで備え付けの買い物かごとこの荷かご１６とを同一規格に統一しておけば、スーパーと顧客との間で次のようなシステムを組むことができる。
すなわち、顧客が自転車１でスーパーへ行ってこの荷かご１６により買い物を済ませ、精算カウンター（レジ）での精算時に、この荷かご１６から商品を次々にスーパー側の空の買い物かごへと移し替えた後、今度は、この移し替えた買い物かご自体をそのまま自転車１に載せて帰宅するというものである。
