Description

【０００１】
【発明の属する技術分野】
本発明は、車両運搬車に関する。
【０００２】
【従来の技術】
従来、車両運搬車の一形態として、荷台の後端部に、後扉を兼用する道板体の基端部を枢支して取り付けると共に、同道板体は、基端部を中心に先端部を上方へ跳ね上げた収納位置と、先端部を下降させて接地した傾斜使用位置との間で起倒自在となしたものがある。
【０００３】
そして、かかる車両運搬車に車両を乗降させる際には、道板体を傾斜使用位置に設定した状態にて、積載する車両又は積み降ろす車両を走行させることにより道板体を介して荷台上に乗降させるようにしている。
【０００４】
【発明が解決しようとする課題】
ところが、図４に示すように、積載する車両ａの最低地上高が低い場合には、道板体10が上り傾斜状態となっているために、前端部ｃが道板体10に当たり、損傷等することがある。
【０００５】
また、道板体10の上に乗り上げた状態でも、積載する車両ａの後端部ｄが地面ｅに当たり、損傷等することがある。
【０００６】
そのために、積載する車両ａの前端部ｃや後端部ｄのバンパー等を一旦取り外して、その後に、車両ａを積み降ろしし、さらにその後に取り外したバンパー等を再度取り付けるという作業を行っているが、かかる作業が非常に煩わしいという不具合がある。
【０００７】
【課題を解決するための手段】
そこで、本発明では、荷台の後端部に、後扉を兼用する道板体の基端部を昇降手段を介して枢支して取り付けると共に、同道板体は、前後伸延幅を運搬する車両の全長と略同等ないしはそれよりも広幅に形成して、基端部を中心に上方へ跳ね上げた収納位置と、先端部を下降させて接地した傾斜使用位置との間で起倒自在となし、昇降手段は、荷台の後端左右側部にそれぞれ立設した支柱の下部にスライド体を上下摺動自在に取り付け、各スライド体と各支柱との間に上下方向に伸縮する昇降用シリンダを介設して、両昇降用シリンダにより両スライド体を介して道板体の基端部を昇降位置調節自在となした車両運搬車において、道板体は、両スライド体に基端部を枢支して取り付けた基端側半部と、同基端側半部の先端部に基端部を枢支して連結した先端側半部とから中折れ状態に折り畳み収納自在に形成し、基端側半部に昇降用ワイヤの先端部を連結する一方、同昇降用ワイヤの基端部を荷台に配設した巻き取り・巻き戻し装置に連結すると共に、先端側半部に伸展用ワイヤの先端部を連結する一方、同伸展用ワイヤの基端部をスライド体に連結して、同先端側半部を伸展状態にて傾斜使用位置に配置することができるようにしたことを特徴とする車両運搬車を提供するものである。
【００１２】
【発明の実施の形態】
以下に、本発明の実施の形態について説明する。
【００１３】
すなわち、本発明に係る車両運搬車は、基本的構造として、荷台の後端部に、後扉を兼用する道板体の基端部を枢支して取り付けると共に、同道板体は、基端部を中心に上方へ跳ね上げた収納位置と、先端部を下降させて接地した傾斜使用位置との間で起倒自在となしている。
【００１４】
そして、特徴的構造として、道板体は、荷台の後端部に昇降手段を介して基端部を枢支して取り付けている。
【００１５】
しかも、昇降手段は、荷台の後端左右側部にそれぞれ立設した支柱の下部にスライド体を上下摺動自在に取り付け、各スライド体と各支柱との間に上下方向に伸縮する昇降用シリンダを介設して、両昇降用シリンダにより両スライド体を介して道板体の基端部を昇降位置調節自在となしている。
【００１６】
さらには、道板体は、折り畳み自在ないしは伸縮自在に形成し、折り畳み自在に形成した場合には、伸展状態と折り畳み状態のいずれかを選択して傾斜使用位置に配置することができるようにしている。
【００１７】
【実施例】
以下に、本発明の実施例を、図面を参照しながら説明する。
【００１８】
図1に示すＡは、本発明に係る車両運搬車であり、同車両運搬車Ａは、荷台１の前端部に運転部２を設け、同運転部２の下方位置と荷台１の後部位置にそれぞれ左右一対の前・後車輪3,3,4,4を設けている。
【００１９】
そして、荷台１の左右側縁部には左・右側支持枠体5,5を立設して、両左・右側支持枠体5,5の前端上部に前部上側荷台６を運転部２の直上方位置にて前方へ張り出し状に固設し、同前部上側荷台６の後端部に中途部上側荷台７の前端部を枢支・連結すると共に、両左右側支持枠体5,5の中途部に中途部上側荷台７の後端部を昇降自在に設け、両左・右側支持枠体5,5の後部に後部上側荷台８の前端部と後端部とをそれぞれ昇降自在に設けている。
【００２０】
また、荷台１の後端部に、後扉を兼用する道板体10の基端部10aを枢支して取り付けると共に、同道板体10は、基端部10aを中心に上方へ跳ね上げた収納位置（イ）と、先端部10bを下降させて接地した傾斜使用位置（ロ）との間で起倒自在となしている。
【００２１】
上記のような構成において、本発明の要旨は、荷台１の後端部に昇降手段11を介して道板体10の基端部10aを枢支して取り付けたことにあり、以下にかかる構成について図２〜図４を参照しながら説明する。
【００２２】
すなわち、昇降手段11は、左・右側支持枠体5,5の後端部に配置した支柱12,12の後面下部に上下方向に伸延するスライドガイド体13,13を設け、各スライドガイド体13,13中にスライド体14,14を上下摺動自在に取り付け、両スライド体14,14の下端部間に左右方向に伸延する道板体支持体15を架設する一方、各スライド体14,14と各支柱12,12の後面中途部との間に昇降用シリンダ16,16を介設して、両昇降用シリンダ16,16を伸縮作動させることにより、上記道板支持体15を昇降位置調節可能としている。
【００２３】
そして、上記道板支持体15には、枢支ブラケット17,17,17を介して左右方向に軸線を向けた枢支ピン18,18,18により道板体10の基端部10aを枢支して取り付けており、同道板体10は、道板支持体15に基端部を枢支して取り付けた基端側半部20と、同基端側半部20の先端部に基端部を枢支して連結した先端側半部21とから中折れ状態に折り畳み収納自在としている。22は枢支ブラケット、23は枢支ピンである。
【００２４】
ここで、上記した道板体10は、起倒手段24により前記した基端部10aである枢支ピン18,18,18を中心に中折れ折り畳み状態にて上方へ跳ね上げた収納位置（イ）と、伸展状態にて先端部10bを下降させて接地した傾斜使用位置（ロ）との間で起倒自在となしている。
【００２５】
そして、起倒手段24は、道板体10の基端側半部20の先端部左右側方位置にそれぞれワイヤ連結ブラケット25,25を介して左右一対の昇降用ワイヤ26,26の先端部26a,26aを連結する一方、両昇降用ワイヤ26,26の基端部を荷台１の右側後部に配設した巻き取り・巻き戻し装置27に連結すると共に、各昇降用ワイヤ26,26の中途部を各支柱12,12の上部と、荷台１の左右側後部と、荷台１の右側後部とにそれぞれ配設した第１・第２・第３プーリ28,28,29,29,30,30に掛け回して、各プーリ28,28,29,29,30,30に各昇降用ワイヤ26,26の中途部をガイドさせている。
【００２６】
しかも、左右一対のスライド体14,14の上部にワイヤ連結ブラケット31,31を介して左右一対の伸展用ワイヤ32,32の基端部32a,32aを連結する一方、道板体10の先端側半部21の中途部左右側方位置にワイヤ連結ブラケット33,33を介して各伸展用ワイヤ32,32の先端部32b,32bを連結すると共に、前記基端側半部20の先端部左右側方位置に設けたワイヤ連結ブラケット25,25よりプーリ支持体34,34を前方に延設し、各プーリ支持体34,34の先端部に第１ガイドプーリ35,35を取り付け、さらに、上記先端側半部21の中途部左右側方位置に設けたワイヤ連結ブラケット33,33に第２ガイドプーリ36,36を取り付けて、各ガイドプーリ35,35,36,36に各伸展用ワイヤ32,32の中途部を掛け回してガイドさせている。
【００２７】
このようにして、昇降用ワイヤ26,26を巻き取り・巻き戻し装置27により巻き取ると、両昇降用ワイヤ26,26に引張されて道板体10の基端側半部20が枢支ピン18,18,18を中心に上方へ跳ね上げられて起立状態となると共に、伸展用ワイヤ32,32が弛緩状態となって、道板体10の先端側半部21が自重により枢支ピン23,23を中心に回動して、収納位置（イ）にて中折れ折り畳み状態にすることができる。
【００２８】
また、道板体10の先端部側21の左右側縁先端部には、固定用ブラケット43,43を設け、同固定用ブラケット43,43を左右一対のスライド体14,14に取り付けた収納位置固定具37,37に固定することにより、道板体10を収納位置固定具37,37により折り畳み状態にて収納位置（イ）に固定するようにしている。
【００２９】
また、昇降用ワイヤ26,26を巻き取り・巻き戻し装置27により巻き戻すと、両昇降用ワイヤ26,26が弛緩されて道板体10の基端側半部20が枢支ピン18,18,18を中心に下方へ回動されて倒伏状態となると共に、伸展用ワイヤ32,32が引張されて、道板体10の先端側半部21を枢支ピン23,23を中心に回動させて伸展状態となして、道板体10の先端部10bを傾斜使用位置（ロ）にて接地状態にすることができる。
【００３０】
この際、道板体10は、かかる傾斜使用位置（ロ）において、昇降手段11の昇降用シリンダ16,16を伸長作動させることにより、左右一対のスライド体14,14を左右一対のスライドガイド体13,13に沿わせて下方へスライド摺動させることができ、両スライド体14,14の下端部間に架設した道板体支持体15を介して道板体10の基端部10aを下方へ移動させて、地面ｅに沿わせた略水平姿勢を採ることができる（略水平使用位置（ハ））。
【００３１】
その結果、かかる道板体10を、基端側が地面ｅから離隔し、かつ、先端側が接地した傾斜姿勢（傾斜使用位置（ロ））から、基端側が地面ｅに近接し、かつ、先端側が接地した略水平姿勢（略水平使用位置（ハ））に姿勢を変更することができる。
【００３２】
ここで、道板体10は、前後伸延幅を運搬する車両ａの全長と略同等ないしはそれよりも広幅に形成して、略水平使用位置（ハ）に設定した道板体10上に車両ａの全体を完全に積載することができ、同状態にて道板体10を傾斜使用位置（ロ）に復元させた場合にも、車両ａの後端部等が地面と干渉することがないようにしている。
【００３３】
従って、車両運搬車Ａに車両ａを積載する場合には、図４に示すように、道板体10を傾斜使用位置（ロ）に設定し、同状態にて、一旦、道板体10の基端部を昇降手段11により下降させて、同道板体10を地面ｅに沿わせた略水平使用位置に設定し、同状態にて道板体10上に車両ａを乗り入れ、同状態てに道板体10の基端部を昇降手段11により上昇させて道板体10を傾斜使用位置（ロ）に復元させ、同状態にて車両ａを荷台１上に乗り入れることができる。
【００３４】
また、車両運搬車Ａに車両ａを降ろす場合には、傾斜使用位置（ロ）に設定した道板体10上に車両ａを後退・移動させ、同状態にて、一旦、道板体10の基端部10aを昇降手段11により下降させて、同道板体10を地面ｅに沿わせた略水平使用位置（ハ）に設定し、同状態にて道板体10上の車両ａを後退・移動させて降ろすことができる。
【００３５】
このようにして、車両ａの最低地上高が低い場合にも、積み降ろし時に車両ａの前・後端部ｃ,ｄが道板体10若しくは地面に当たるのを防止することができて、同車両ａの損傷等を確実に回避することができる。
【００３６】
また、道板体10の基端側半部20の先端部には、図1〜図４に示すように、左右一対の補助支持脚体38,38を設けており、各補助支持脚体38,38は、基端側半部20に基端部を左右方向に軸線を向けた枢軸39,39により枢支して、各枢軸39,39を中心に下方へ垂下させた使用位置と基端側半部20に沿わせた収納位置との間で出し入れ自在となして、姿勢を変更可能としている。
【００３７】
そして、補助支持脚体38,38は、車両ａを道板体10上にて乗降移動させる際に、同車両の重量が大きい場合には、一旦、道板体10を傾斜使用位置（ロ）に姿勢を変更して、同状態にて補助支持脚体38,38を使用位置に設定して、道板体10を補助的に支持させることができるようにしている。
【００３８】
従って、補助支持脚体38,38が不要の際には、両補助支持脚体38,38を収納位置に姿勢を変更して、道板体10の基端部10aの昇降が行えるようにしている。
【００３９】
〔変容例としての道板体の説明〕
図５〜図７は、前記した第１実施例としての道板体10の変容例としての道板体10を示しており、同道板体10は、折り畳み状態にて収納位置（イ）と傾斜使用位置（ロ）との間で起倒可能として、傾斜使用位置（ロ）にて補助道板体40を着脱自在に取り付けることにより、車両ａを車両運搬車Ａの荷台１に積み降ろしすることができるようにしている。
【００４０】
すなわち、変容例としての道板体10は、前記した第１実施例としての道板体10と基本的構造を同じくしているが、基端側半部20の左・右側縁基端部に道板側連結ブラケット41,41を突設して、各道板側連結ブラケット41,41とスライド体14,14の上部に突設したワイヤ連結ブラケット31,31とに、伸展用ワイヤ32,32の基端部32a,32aを選択的に付け替え自在としている。42は連結金具である。
【００４１】
このようにして、伸展用ワイヤ32,32の基端部32a,32aを連結金具42,42を介してワイヤ連結ブラケット31,31に連結した場合には、前記したように起倒手段24により折り畳み状態の道板体10を倒伏させると、伸展用ワイヤ32,32が引張されて、同道板体10を伸展状態となすことができるが、伸展用ワイヤ32,32の基端部32a,32aを連結金具42,42を介して道板側連結ブラケット41,41に連結した場合には、伸展用ワイヤ32,32は引張されることがないため、折り畳み状態のまま倒伏させることができる。
【００４２】
従って、道板体10は、車両ａの最低地上高や、同車両ａを積み降ろしする場所等の条件に応じて、伸展させた状態ないしは折り畳み状態のいずれかを選択して、適宜いずれかの形態にて使用することができる。
【００４３】
また、道板体10の先端側半部21の左右側縁先端部には、固定用ブラケット43,43を突設しており、同固定用ブラケット43,43は、基端側半部20の左右側縁基端部に突設した道板側連結ブラケット41,41に、連結ボルト44,44を介して連結することにより、道板体10を折り畳み状態に保持させることができるようにしている。
【００４４】
〔第２実施例としての道板体の説明〕
図８及び図９は、第２実施例としての道板体10を示しており、同道板体10は、前記した第１実施例としての道板体10と同様に、昇降手段11により昇降自在とすると共に、起倒手段24により起倒自在としているが、伸縮自在に形成している点で異なる。
【００４５】
すなわち、第２実施例としての道板体10は、基端側半部20に先端側半部21を伸縮自在に取り付けており、基端側半部20の左右側縁部に前後方向に伸延する左右一対のガイドレール45,45を設ける一方、先端側半部21の左右側縁部に上記ガイドレール45,45に沿って転動する第１・第２転動輪46,46,47,47を取り付けて、同先端側半部21を基端側半部20に沿わせて伸延方向にスライドさせることにより、伸縮させることができるようにしている。
【００４６】
そして、各ガイドレール45は、前後方向に伸延する側壁レール形成片45aと、同側壁レール形成片45aの上・下端より内方へ張り出し状に形成した上・下部レール形成片45b,45cとから、内方が開口する断面コ字状に形成し、上・下部レール形成片45b,45cにそれぞれ上下方向に符合する多数の固定ピン挿通孔48,49を各上・下部レール形成片45b,45cの伸延方向に一定の間隔を開けて形成している。
【００４７】
また、先端側半部21の左右側縁部の基端部側には、それぞれ左右方向に軸線を向けた第１転動輪支軸50,50,50,50を介して第１転動輪46,46,46,46を転動自在に取り付けると共に、それぞれ上下方向に軸線を向けた第２転動輪支軸51,51,51,51を介して第２転動輪47,47,47,47を転動自在に取り付けている。52は転動輪取付ブラケットである。
【００４８】
このようにして、先端側半部21に取り付けた上記第１・第２転動輪46,46,47,47を、基端側半部20に設けたガイドレール45,45内に配置して、第１転動輪46は上・下部レール形成片45b,45c上を転動する一方、第２転動輪47は側壁レール形成片45a上を転動するようにしている。
【００４９】
そして、第１転動輪46,46の前部と後部に位置する上・下部レール形成片45b,45cの固定ピン挿通孔48,49中に、固定ピン53,53をそれぞれ挿通することにより、先端側半部21を所要の伸縮位置にて基端側半部20に固定することができるようにしている。
【００５０】
【発明の効果】
本発明によれば、次のような効果が得られる。
【００５１】
すなわち、本発明では、道板体は、両スライド体に基端部を枢支して取り付けた基端側半部と、同基端側半部の先端部に基端部を枢支して連結した先端側半部とから中折れ状態に折り畳み収納自在に形成し、基端側半部に昇降用ワイヤの先端部を連結する一方、同昇降用ワイヤの基端部を荷台に配設した巻き取り・巻き戻し装置に連結すると共に、先端側半部に伸展用ワイヤの先端部を連結する一方、同伸展用ワイヤの基端部をスライド体に連結して、同先端側半部を伸展状態にて傾斜使用位置に配置することができるようにしている。
【００５２】
このようにして、昇降用ワイヤを巻き取り・巻き戻し装置により巻き取ると、両昇降用ワイヤに引張されて道板体の基端側半部が上方へ跳ね上げられて起立状態となると共に、伸展用ワイヤが弛緩状態となって、道板体の先端側半部が自重により回動して、収納位置にて中折れ折り畳み状態にすることができる。
【００５３】
また、昇降用ワイヤを巻き取り・巻き戻し装置により巻き戻すと、両昇降用ワイヤが弛緩されて道板体の基端側半部が下方へ回動されて倒伏状態となると共に、伸展用ワイヤが引張されて、道板体の先端側半部を回動させて伸展状態となして、道板体の先端部を傾斜使用位置にて接地状態にすることができる。
【００５４】
この際、道板体は、かかる傾斜使用位置において、昇降手段の昇降用シリンダを伸長作動させることにより、左右一対のスライド体を下方へスライド摺動させることができ、両スライド体を介して道板体の基端部を下方へ移動させて、地面に沿わせた略水平姿勢を採ることができる（略水平使用位置）。
【００５５】
その結果、かかる道板体を、基端側が地面から離隔し、かつ、先端側が接地した傾斜姿勢（傾斜使用位置）から、基端側が地面に近接し、かつ、先端側が接地した略水平姿勢（略水平使用位置）に姿勢を変更することができる。
【００５６】
ここで、道板体は、前後伸延幅を運搬する車両の全長と略同等ないしはそれよりも広幅に形成しているため、略水平使用位置に設定した道板体上に車両の全体を完全に積載することができ、同状態にて道板体を傾斜使用位置に復元させた場合にも、車両の後端部等が地面と干渉することがない。
【００５７】
従って、車両運搬車に車両を積載する場合には、道板体を傾斜使用位置に設定し、同状態にて、一旦、道板体の基端部を昇降手段により下降させて、同道板体を地面に沿わせた略水平使用位置に設定し、同状態にて道板体上に車両を乗り入れ、同状態にて道板体の基端部を昇降手段により上昇させて道板体を傾斜使用位置に復元させ、同状態にて車両を荷台上に乗り入れることができる。
【００５８】
また、車両運搬車に車両を降ろす場合には、傾斜使用位置に設定した道板体上に車両を後退・移動させ、同状態にて、一旦、道板体の基端部を昇降手段により下降させて、同道板体を地面に沿わせた略水平使用位置に設定し、同状態にて道板体上の車両を後退・移動させて降ろすことができる。
【００５９】
このようにして、車両の最低地上高が低い場合にも、積み降ろし時に車両の前・後端部が道板体若しくは地面に当たるのを防止することができて、同車両の損傷等を確実に回避することができる。

Connect to the winding / rewinding device and connect the tip of the extension wire to the tip half, while connecting the base end of the extension wire to the slide body and extend the tip half It can be arranged at the tilt use position in the state.
[0052]
In this way, when the lifting wire is wound by the winding / unwinding device, it is pulled by both lifting wires and the base end side half of the road plate body is flipped upward to be in an upright state, The extension wire is in a relaxed state, and the tip half of the road plate body is rotated by its own weight, and can be folded into a folded state at the storage position.

[0054]
At this time, the road plate body can slide the pair of left and right slide bodies downward by extending the lifting / lowering cylinder of the lifting / lowering means at the inclined use position. By moving the base end of the plate body downward, it is possible to take a substantially horizontal posture along the ground (substantially horizontal use position).
[0055]
As a result, the road plate body has a substantially horizontal posture in which the base end side is close to the ground and the distal end side is grounded from an inclined posture (tilt use position) where the proximal end side is separated from the ground and the distal end side is grounded. The posture can be changed to a substantially horizontal use position.
[0056]
Here, since the road plate body is formed to be substantially equal to or wider than the entire length of the vehicle carrying the front / rear extension width, the entire vehicle is completely mounted on the road plate body set at the substantially horizontal use position. Even when the road plate body is restored to the inclined use position in the same state, the rear end portion of the vehicle does not interfere with the ground.
[0057]
Therefore, when loading a vehicle on a vehicle transport vehicle, the road plate body is set to the inclined use position, and in this state, the base end portion of the road plate body is once lowered by the lifting and lowering means. Is set to a substantially horizontal use position along the ground, and the vehicle is put on the road plate body in the same state, and the road plate body is inclined by raising and lowering the base end portion of the road plate body in the same state by the lifting means. It can be restored to the use position and the vehicle can be put on the loading platform in the same state.
[0058]
In addition, when the vehicle is lowered to the vehicle transporter, the vehicle is moved back and moved on the road plate body set to the inclined use position, and the base end portion of the road plate body is once lowered by the lifting means in the same state. Thus, the road plate body can be set at a substantially horizontal use position along the ground, and the vehicle on the road plate body can be moved backward and moved down in the same state.
[0059]
In this way, even when the minimum ground clearance of the vehicle is low, it is possible to prevent the front and rear ends of the vehicle from hitting the road plate body or the ground when loading and unloading, so that damage to the vehicle can be ensured. It can be avoided.
