Description

【0001】
【発明の属する技術分野】
本発明は、自動四輪車、自動二輪車を運搬する自動車運搬車のリヤゲート装置及び該リヤゲート装置を備えた自動車運搬車に関する。
【0002】
【従来の技術】
従来、荷台の後端近傍にリヤゲート装置を備えた自動車運搬車が広く使用されている。リヤゲートは、被運搬自動車を荷台に積み込むための道板部材を備えると共に該道板部材の基端近傍の回転支持部で荷台の後端床面近傍に車幅方向の軸廻りに回転自在に支持され、該道板部材の自由端が荷台の後方に突出して自由端において地面に接地する開位置及び該道板部材の自由端が荷台の後端床面近傍から上方に突出する姿勢で収納される閉位置の間で開閉自在とされている。
【0003】
一般的に、被運搬自動車が四輪の被運搬自動四輪車である場合、開位置とされて後方に下り傾斜したリヤゲートの道板部材上を被運搬自動四輪車が自走することにより、荷積み及び荷降ろしが行われる。
【0004】
一方、被運搬自動車が新車の自動二輪車である場合もリヤゲートの道板部材上を通って荷積み及び荷降ろしが行われるが、自動二輪車の場合、新車であることをアピールするために工場からの出荷、運搬の際は一般的に、エンジンを始動しないという慣習がある。このため、被運搬自動二輪車の荷積み及び荷降ろしは一般的に作業者の人力により行われる。
【0005】
【発明が解決しようとする課題】
しかしながら、例えばフロントスポイラ等が装着され、車両前下端部と地面との隙間が特に小さい被運搬自動四輪車(以下、「ローダウン車」という)の場合、荷積みの際、後方に下り傾斜した道板部材に車両前下端部が干渉することがある。
【0006】
又、被運搬自動二輪車の中には大型で重量が重く、人力による荷積み、荷降ろしが困難なものも存在する。
【0007】
これに対し、リヤゲートの後方に他の道板を継ぎ足せば、道板の傾斜角が小さくなるので、上記問題を解決しうるが、荷台の後方に広い作業スペースが必要となるので、実用上好ましくない。
【0008】
本発明は、以上の問題点に鑑みてなされたものであって、荷台後方の作業スペースが狭い場合であってもローダウン車、大型自動二輪車等の荷積み、荷降ろしを容易に行うことができる自動車運搬車のリヤゲート装置及び該リヤゲート装置を備えた自動車運搬車を提供することをその課題とする。
【0009】
【課題を解決するための手段】
本発明は、荷台の後端近傍の車幅方向両側に上下方向に配設された一対のガイドレールと、該ガイドレールに案内されて昇降自在とされたゲートスライダと、被運搬自動車を前記荷台に積み込むための道板部材を備えると共に該道板部材の基端近傍の回転支持部で前記ゲートスライダに前記車幅方向の軸廻りに回転自在に支持され、該道板部材の自由端が前記荷台の後方に突出して地面に接地する開位置及び該道板部材の自由端が前記荷台の後端床面近傍から上方に突出する姿勢で収納される閉位置の間で開閉自在、且つ、該道板部材の基端が前記荷台の後端床面近傍及び地面近傍の間で昇降自在とされたリヤゲートと、該リヤゲートにおける前記回転支持部よりも前記道板部材の自由端側の部位及び前記荷台における前記後端床面よりも上方の部位の間に伸縮自在に連結され、前記リヤゲートを上方に付勢可能とされたシリンダ機構と、前記リヤゲート及び前記ゲートスライダの間に着脱自在とされ、装着状態で前記リヤゲートの前記開位置側への回転を規制して前記道板部材を略水平な姿勢に保持可能とされた水平保持部材と、を含んでなり、前記道板部材を略水平な姿勢に保持して昇降させる水平保持昇降及び前記道板部材の自由端が地面に接地した状態で該道板部材の基端を昇降させる揺動昇降のいずれかの態様の昇降を選択的に実行可能とされたことを特徴とする自動車運搬車のリヤゲート装置、により上記課題を解決したものである。
【0010】
又、前記リヤゲートは、被運搬自動四輪車が走行可能であるように前記道板部材が車幅方向両側に一対配設され、且つ、該一対の道板部材の間に配設された該道板部材よりも短い板状体で被運搬自動二輪車を載置可能である自動二輪車載置部材を備える構成としてもよい。
【0011】
更に、前記リヤゲートは、前記道板部材の自由端近傍に配設されて前記揺動昇降の際に地面に接地して車両前後方向に転動するようにされた車輪を備える構成としてもよい。
【0012】
又、本発明は上記自動車運搬車のリヤゲート装置を備えたことを特徴とする自動車運搬車により上記課題を解決したものである。
【0013】
本発明によれば、荷台後方の作業スペースが狭い場合であってもローダウン車、大型自動二輪車等を自動車運搬車の荷台に容易に積み込むことができる。
【0014】
【発明の実施の形態】
以下、本発明の実施形態を、図面を参照して詳細に説明する。
【0015】
図1は、本実施形態に係る自動車運搬車10の後部近傍の構造を示す側面図である。図2は、自動車運搬車10のリヤゲート装置12の平面図である。
【0016】
リヤゲート装置12は、荷台14の後端14A近傍の車幅方向両側に上下方向に配設された一対のガイドレール16と、ガイドレール16に案内されて昇降自在とされたゲートスライダ18と、被運搬四輪自動車20A(図10〜図13参照)、被運搬二輪自動車20Bを荷台14に積み込むための道板部材22を備えると共に道板部材22の基端22A近傍の回転支持部26Aでゲートスライダ18に車幅方向の軸廻りに回転自在に支持され、道板部材22の自由端22Bが荷台14の後方に突出して地面24に接地する開位置及び該道板部材22の自由端22Bが荷台14の後端床面14B近傍から上方に突出する姿勢で収納される閉位置の間で開閉自在とされ、且つ、道板部材22の基端22Aが荷台14の後端床面14B近傍及び地面24近傍の間で昇降自在とされたリヤゲート26と、リヤゲート26における回転支持部26Aよりも道板部材22の自由端22B側の部位及び荷台14における後端床面14Bよりも上方の部位の間に伸縮自在に連結され、リヤゲート26を上方に付勢可能とされたシリンダ機構28と、リヤゲート26及びゲートスライダ18の間に着脱自在とされ、装着状態でリヤゲート26の開位置側への回転を規制して道板部材22を略水平な姿勢に保持可能とされた水平保持部材30と、を含んでなり、道板部材22を略水平な姿勢に保持して昇降させる水平保持昇降及び道板部材22の自由端22Bが地面24に接地した状態で道板部材22の基端22Aを昇降させる揺動昇降のいずれかの態様の昇降を選択的に実行可能とされたことを特徴としている。
【0017】
他の構成については、従来の自動車運搬車のリヤゲート装置と同様であるので説明を適宜省略する。
【0018】
荷台14は、被運搬自動車として被運搬自動四輪車20A及び被運搬自動二輪車20Bを搭載可能とされ、これら被運搬自動車を固定するための固縛装置(図示省略)を備えている。又、荷台14の後端14A近傍の車幅方向両側には上方に突出する一対の支柱14Cが設置されている。
【0019】
図3は、ガイドレール16周辺の構造を拡大して示す平面図である。
【0020】
ガイドレール16は、断面略コ字形状の棒状部材で車幅方向内側が開口するように支柱14Cの下端近傍後面に取付けられている。尚、ガイドレール16の前後方向の一対の開口端は相互に相手側に突出したリップ部16A、16Bとされており、これらリップ部16A、16Bの間が開口している。
【0021】
ゲートスライダ18は、ガイドレール16の内側に摺動自在に嵌合する一対のスライダ34と、車幅方向に配置された棒状体で両端が一対のスライダ34の下端近傍に連結されたスライドバー36と、を有して構成されている。
【0022】
スライダ34は、上下方向に配置された角パイプ状の部材でガイドレール16に案内されつつスライドバー36が少なくとも地面24の近傍まで下降可能であるような長さを有している。
【0023】
図4、図5はスライダ34周辺の構造を更に拡大して示す側面図である。
【0024】
ゲートスライダ18は、スライドバー36に上方から当接して上昇を規制するようにガイドレール16に取付けられた固定ストッパ38により昇降の上限位置が制限されている。
【0025】
更に、ゲートスライダ18は、可動ストッパ機構40により、上限位置に保持可能とされている。スライダ34が上限に保持された状態でスライドバー36が荷台14の後端床面14Bの近傍に位置するようにされている。
【0026】
可動ストッパ機構40は、スライダ34の内側に基端部42Aが回転自在に支持され、先端部42Bがスライダ34から外側に突出自在、且つ、スライダ34の内側に引き込み自在とされた可動部材42と、先端部42Bが突出する方向に可動部材42を付勢するばね44と、ばね44の付勢力に抗して先端部42Bが引き込む方向に可動部材42を回転可能であるカム機構46と、手動によりカム機構46を駆動可能である手動レバー48と、を含んで構成されている。
【0027】
可動部材42の先端部42Bは突出状態で下面が略水平、且つ、側面が突出方向に下り傾斜するような形状とされている。尚、ゲートスライダ18が上限位置で可動部材42の先端部42Bが突出可能であるように、ガイドレール16には先端部42Bが貫通可能である貫通孔16Cが形成されており、貫通孔16Cの下端外側には突出状態の先端部42Bの下端に下方から当接して支持する受け部材50が配設されている。更に、ゲートスライダ18が上限位置で手動レバー48を操作可能であるようにガイドレール16には作業孔16Dが形成されている。
【0028】
又、スライダ34の上端近傍にはブラケット34Aを介してフック34Bが取付けられている。
【0029】
リヤゲート26は、2本の道板部材22と、被運搬自動二輪車20Bを載置可能である自動二輪車載置部材52と、を有して構成されている。
【0030】
道板部材22は、略長方形の板状体で車幅方向の溝が長手方向適宜なピッチで多数形成され、被運搬自動四輪車20Aが走行可能であるように被運搬自動四輪車20Aのトレッド幅に合わせてリヤゲート26の車幅方向両側に2本配設されている。2本の道板部材22は非走行面側において車幅方向の第1、第2のクロスメンバ54、56で連結されている。
【0031】
尚、第1のクロスメンバ54は、道板部材22の基端22Aよりも自由端22B側に若干離間して配設され、第2のクロスメンバ56は、道板部材22の長手方向中央近傍に配設されている。又、これら第1、第2のクロスメンバ54、56は両端が道板部材22よりも車幅方向に若干突出している。
【0032】
図6に示されるように、第2のクロスメンバ56の両端にはフック56Aが取付けられている。又、第2のクロスメンバ56の両端近傍にはリヤゲート26を閉位置に保持するためのロック機構58が備えられている。
【0033】
自動二輪車載置部材52は、道板部材22よりも短い略長方形の板状体のエキスパンドメタルをフレームに取付けた構造で、一端が道板部材22の基端22Aにほぼ一致するように2本の道板部材22の間に配置され、第1、第2のクロスメンバ54、56に取付けられている。尚、載置される被運搬自動二輪車20Bのスタンドの位置に対応して上面の一部に縞鋼板52Aが配設されている。
【0034】
リヤゲート26は、2本の道板部材22それぞれの基端22Aの近傍の回転支持部26Aでゲートスライダ18のスライドバー36に車幅方向のピン(図示省略)を介して支持されている。
【0035】
図7は、道板部材22の自由端22B周辺の構造を拡大して示す平面図、図8は同側面図である。
【0036】
道板部材22の自由端22B近傍の車幅方向両側には車輪60が備えられ、車幅方向の車軸62を介して軸支されている。車輪60は、道板部材22の揺動昇降の際に地面24に接地して車両前後方向に転動可能とされている。
【0037】
更に、2本の道板部材22の自由端22Bにはそれぞれ係合部材64を介して補助道板部材66が係合されている。補助道板部材66は、道板部材22の幅とほぼ等しい幅を有し、道板部材22よりも短い板状体で、閉位置のリヤゲート26の前面に折り重ねた状態で収納可能であるとともに、開位置のリヤゲート26における道板部材22の後方で地面24に接地可能とされている。
【0038】
係合部材64は、長孔64Aが形成された板状体で、道板部材22及び車輪60の間に挟まれるように道板部材22の自由端22Bの車幅方向両側に配設され、車軸62が長孔64Aを貫通している。又、係合部材64は、長孔64Aを貫通する車幅方向のピン68を介して補助道板部材66の基端66Aに回転自在に係合されている。
【0039】
シリンダ機構28は具体的には、シリンダ部28Aからロッド部28Bが摺動自在に突出した油圧シリンダで、荷台14の後端14A近傍の車幅方向両側に一対配設され、シリンダ部28A側の端部において荷台14の支柱14Cの上端近傍に回転自在に連結され、ロッド部28Bの端部においてリヤゲート26の第1のクロスメンバ54の端部近傍に回転自在に連結されている。又、シリンダ機構28は昇降スイッチ68を操作することにより、図示しない油圧機構により作動油が給排されて伸縮するようにされている。
【0040】
水平保持部材30は、前記図6に示されるように、具体的には、チェーン30Aの両端にフック30Bが取付けられた構造で、2本用意されている。水平保持部材30は、一方のフック30Bがスライダ34の上端近傍のフック34Aに係合され、他方のフック30Bがリヤゲート26の第2のクロスメンバ56の端部近傍のフック56Aに係合され、装着状態で道板部材22の開位置側への回転を規制して道板部材22を略水平な状態に保持するような長さを有している。尚、水平保持部材30は、非装着時はリヤゲート26の第2のクロスメンバ56の両端近傍に格納される。
【0041】
次に、リヤゲート装置12の作用について説明する。
【0042】
まず、被運搬自動二輪車20Bを荷台14に積み込む際の作用について説明する。
【0043】
リヤゲート26は、荷積み、荷降ろし作業以外は通常閉位置とされ、荷台14の後端14A近傍に収納されている。又、ゲートスライダ18は、上限位置に保持されている。
【0044】
まず作業者は、リヤゲート26のロック機構58を解除してから昇降スイッチ68を操作してシリンダ機構28を伸長させ、リヤゲート26を後方に回転させ、道板部材22及び自動二輪車載置部材52が水平よりも若干後方に上り傾斜する状態になったところで、リヤゲート26の回転を停止させる。
【0045】
ここで、リヤゲート26に収納されている水平保持部材30を取り出して両端のフック30Bをスライダ34のフック34B、リヤゲート26のフック56Aに係合する。
【0046】
この状態で、昇降スイッチ68を操作して水平保持部材30が緊張するまでシリンダ機構28を若干伸長させると、道板部材22及び自動二輪車載置部材52が略水平状態となる。
【0047】
次に、昇降スイッチ68を操作し、シリンダ機構28を収縮させてゲートスライダ18を僅かに上昇させ、可動ストッパ機構40の可動部材42を受け部材50から上方に離間させる。ここで、手動レバー48を操作してばね44の付勢力に抗して可動部材42の先端部42Bを引き込ませる。尚、カム機構46により可動部材42の引き込み状態が保持される。
【0048】
この状態で昇降スイッチ68を操作してシリンダ機構28を更に伸長させるとゲートスライダ18が下降し、リヤゲート26は道板部材22及び自動二輪車載置部材52が略水平な姿勢に保持された状態で下降する。ゲートスライダ18又はリヤゲート26の一部が接地したところで昇降スイッチ68を操作してリヤゲート26の下降を停止させる。これにより、道板部材22及び自動二輪車載置部材52が略水平な姿勢で地面24に接地又は近接した状態となる。
【0049】
作業者は、人力により被運搬自動二輪車20Bを押して自動二輪車載置部材52上に乗り込ませると共に、被運搬自動二輪車20Bのスタンドが縞鋼板52A上に当接するように載置する(図1参照)。自動二輪車載置部材52が略水平な姿勢で地面24に接地又は近接しているので、被運搬自動二輪車20Bの重量が重い場合であってもこの作業は容易である。
【0050】
次に、手動レバー48を操作して可動部材42の先端部42Bを突出させてから、昇降スイッチ68を操作してシリンダ機構28を収縮させてゲートスライダ18を上昇させる。
【0051】
可動部材42は、先端部42Bがガイドレール16に当接すると側面においてガイドレール16の内周面に案内されてばね44の付勢力に抗して引き込み、ゲートスライダ18が上限位置の近傍まで上昇すると可動部材42の先端部42Bが再突出する。スライドバー36が固定ストッパ38に当接したところで昇降スイッチ68を操作して上昇を停止させる。
【0052】
これにより、自動二輪車載置部材52は略水平状態に保持されて荷台14の後端床面14Bの近傍まで上昇する。
【0053】
ここで、昇降スイッチ68を操作してゲートスライダ18を僅かに下降させ、可動部材42の先端部42Bを受け部材50に当接させる。
【0054】
この状態で作業者は人力により、被運搬自動二輪車20Bを押して自動二輪車載置部材52上から荷台14に積み込む。自動二輪車載置部材52が荷台14の後端床面14Cの近傍で略水平状態に保持されているので被運搬自動二輪車20Bの重量が重い場合であってもこの積み込み作業は容易である。更に、被運搬自動二輪車20Bを荷台14の所定の位置に搭載する。
【0055】
次に、昇降スイッチ68を操作してゲートスライダ18を僅かに上昇させ、可動部材42の先端部42Bを受け部材50から上方に離間させる。ここで手動レバー48を操作して可動部材42を引き込ませ、更に、昇降スイッチ68を操作して、リヤゲート26を地面24に接地するまで下降させる。
【0056】
以後、同様に被運搬自動二輪車20Bの荷積み作業を繰り返す。総ての被運搬自動二輪車20Bを荷台14に搭載してからこれら被運搬自動二輪車20Bを荷台14に固縛する。又、ゲートスライダ18を上限位置に保持した状態で、ゲートスライダ18を閉位置の方向に僅かに回転させて水平保持部材30の両端のフック30Bをスライダ34のフック34B、リヤゲート26のフック56Aから取り外し、水平保持部材30をリヤゲート26の所定の収納位置に収納する。
【0057】
更に、昇降スイッチ68を操作してゲートスライダ18を閉位置まで回転させて荷台14の後端14Aに収納し、ロック機構58で閉位置に固定する。
【0058】
これにより、被運搬自動二輪車20Bの荷積み作業が完了し、自動車運搬車10が走行可能となる。尚、荷降ろしの場合も、自動二輪車載置部材52の水平保持昇降を利用して上記と逆の手順で被運搬自動二輪車20Bの荷降ろし作業を行えばよい。
【0059】
リヤゲート26は、2本の道板部材22の間に自動二輪車載置部材52が配設された構造であるが、自動二輪車載置部材52は道板部材22よりも長さが短く、更にエキスパンドメタルを主要部材とした構造であるので空力抵抗が小さい。尚、自動二輪車載置部材52の一部は縞鋼板52Aで閉塞されているが、閉塞された領域は一部に限定されているのでその影響は小さい。
【0060】
次に、被運搬自動四輪車20Aの荷積み作業におけるリヤゲート装置12の作用について説明する。
【0061】
作業者はまず、閉位置のリヤゲート26のロック機構58を解除してから昇降スイッチ68を操作してシリンダ機構28を伸長させ、道板部材22の自由端22Bの車輪60が地面24に接地するまでリヤゲート26を後方に回転させる。
【0062】
次に、手動により補助道板部材66を後方に折り返し、(係合部材64の長孔64Aが許容する範囲で)道板部材22から後方に最も遠ざかるように地面24上に載置する。
【0063】
図10に示されるように、通常はこの状態で補助道板部材66、道板部材22上を被運搬自動四輪車20Aが自走することにより荷積み、荷降ろし作業が行われる。
【0064】
しかし、図11に示されるように、被運搬自動四輪車20Aがローダウン車の場合、傾斜した道板部材22の上面に車両前下端部が干渉することがある。
【0065】
このようなローダウン車の荷積みを行う場合は、まず昇降スイッチ68を操作し、シリンダ機構28を収縮させてゲートスライダ18を僅かに上昇させ、可動ストッパ機構40の可動部材42を受け部材50から上方に離間させる。更に、手動レバー48を操作してばね44の付勢力に抗して可動部材42の先端部42Bを引き込み状態に保持する。
【0066】
この状態で昇降スイッチ68を操作してシリンダ機構28を伸長させるとリヤゲート26は揺動し、道板部材22の基端22Aが下降する。基端22Aの下降に伴い、自由端22Bは後方へ若干移動するが、車輪60が転動するので地面と摺れることなく移動可能である。又、係合部材64は長孔64Aを有しているので、道板部材22の自由端22Bが後方へ水平移動しても、補助道板部材66が連動して後方へ移動することはない。
【0067】
道板部材22の基端22Aが地面24の近傍まで下降し、道板部材22が略水平な姿勢となったところで昇降スイッチ68を操作してシリンダ機構28の伸長を停止する。
【0068】
次に、図12に示されるように、被運搬自動四輪車20Aを、補助道板部材66から道板部材22上に自走により乗り込ませる。
【0069】
道板部材22は略水平状態であり、更に、補助道板部材66により乗り込む際の段差が小さくされているので、被運搬自動四輪車20Aがローダウン車であっても車両前下端部が道板部材22の上面に干渉することなく乗り込み可能である。
【0070】
次に、被運搬自動四輪車20Aのサイドブレーキ(図示省略)をかけ、更に手動レバー48を操作して可動部材42の先端部42Bを突出させてから、昇降スイッチ68を操作してシリンダ機構28を収縮させると、ゲートスライダ18がガイドレール16に案内されて上昇し、道板部材22の基端22Aも上昇する。
【0071】
図13に示されるように、道板部材22の基端22Aが上昇すると、被運搬自動四輪車20Aはその後輪と補助道板部材66との接触部を支点として、前上がりに傾斜して上昇する。
【0072】
可動部材42は、先端部42Bがガイドレール16に当接すると側面においてガイドレール16の内周面に案内されてばね44の付勢力に抗して引き込み、ゲートスライダ18が上限位置の近傍まで上昇すると可動部材42の先端部42Bが再突出する。スライドバー36が固定ストッパ38に当接したところで昇降スイッチ68を操作して上昇を停止させる。道板部材22の基端22Aは荷台14の後端床面14Cの近傍まで上昇する。
【0073】
ここで、昇降スイッチ68を操作してゲートスライダ18を僅かに下降させ、可動部材42の先端部42Bを受け部材50に当接させる。
【0074】
道板部材22の基端22Aの上昇に伴い、道板部材22の自由端22Bは前方へ移動するが、車輪60が転動するので地面と摺れることはなく、又、係合部材64は長孔64Aを有しているので、道板部材22の自由端22Bの前方への移動に連動して補助道板部材66が前方へ移動することはない。
【0075】
被運搬自動四輪車20Aのサイドブレーキを解放してから、自走により被運搬自動四輪車20Aを荷台14に乗り込ませて、荷台14の所定の位置に搭載する。道板部材22の基端22Aが荷台14の後端床面14Cの近傍に配置されているので、被運搬自動四輪車20Aは荷台14に干渉することなく乗り込むことができる。
【0076】
次に、昇降スイッチ68を操作してゲートスライダ18を僅かに上昇させ、
可動部材42の先端部42Bを受け部材50から離間させる。この状態で手動レバー48を操作して可動部材42を引き込ませ、更に、昇降スイッチ68を操作して道板部材22の基端22Aを地面24の近傍まで下降させる。
【0077】
以後、同様に被運搬自動四輪車20Aの荷積み作業を繰り返す。総ての被運搬自動四輪車20Aの荷台14への搭載が完了したら、これら搭載した被運搬自動四輪車20Aを荷台14に固縛する。

【0082】
更に、リヤゲート装置12は、揺動昇降で被運搬自動四輪車20Aの前輪側のみを昇降させ、又、水平保持昇降では被運搬自動二輪車20Bを昇降させるものであり、被運搬自動四輪車20A全体を昇降させることがないのでシリンダ機構28の容量をそれだけ小さくすることができ、この点でも軽量、コンパクトで低コストである。
【0083】
又、リヤゲート装置12は水平保持部材30が、チェーン30Aの両端にフック30Bが取付けられた簡単な構造であり、この点でも軽量、コンパクトで低コストである。更に、このような構造が簡単な水平保持部材30の着脱により、水平保持昇降及び揺動昇降を容易に選択することができ、この点でも作業効率がよい。
【0084】
尚、本実施形態では、リヤゲート26は、道板部材22の自由端22Bに車輪60を備えているが、本発明はこれに限定されるものではなく、摩擦を小さくする部材を用いたり、角Rを大きくする等の手段により、道板部材22の自由端22Bが地面上を滑動可能である構成としてもよい。
【0085】
又、本実施形態では、可動ストッパ機構40により半自動的にゲートスライダ18を上限位置に保持する構造であるが、例えば手動により着脱するタイプのストッパによりゲートスライダ18を上限位置に保持・解放可能な構成としてもよい。
【0086】
又、本実施形態では、道板部材22の自由端22Bに補助道板部材66を係合し、被運搬自動四輪車20Aは補助道板部材66を通り、道板部材22に乗り込むようにされているが、略水平状態の道板部材22に干渉することなく直接乗り込むことができる地上高をローダウン車が有している場合には補助道板部材66を省略してもよい。
【0087】
更に、本実施形態では、リヤゲート26は、被運搬自動四輪車20Aのトレッド幅に合わせて配設された2本の道板部材22の間に自動二輪車載置部材52が配設された構成であるが、本発明はこれに限定されるものではなく、例えば、道板部材及び自動二輪車載置部材を一体の板状体としてもよい。又、道板部材が自動二輪車載置部材を兼ねるようにしてもよい。
【0088】
更に又、本実施形態では、係合部材64は長孔64Aを有する板状体であるが、本発明はこれに限定されるものではなく、丸棒材を略長円形状に成形した係合部材としてもよく、道板部材22と補助道板部材66とを係合するワイヤ又はチェーンの係合部材としてもよい。
【0089】

Further, the cylinder mechanism 28 is adapted to be expanded and contracted by operating a lift switch 68 so that hydraulic oil is supplied and discharged by a hydraulic mechanism (not shown).
[0040]
Specifically, as shown in FIG. 6, two horizontal holding members 30 are prepared with a structure in which hooks 30B are attached to both ends of the chain 30A. The horizontal holding member 30 has one hook 30B engaged with a hook 34A near the upper end of the slider 34, and the other hook 30B engaged with a hook 56A near the end of the second cross member 56 of the rear gate 26, The length is such that the road plate member 22 is held in a substantially horizontal state by restricting the rotation of the road plate member 22 toward the open position in the mounted state. The horizontal holding member 30 is stored in the vicinity of both ends of the second cross member 56 of the rear gate 26 when not mounted.
[0041]
Next, the operation of the rear gate device 12 will be described.
[0042]
First, an operation when the transported motorcycle 20B is loaded on the loading platform 14 will be described.
[0043]
The rear gate 26 is normally closed except for loading and unloading operations, and is housed near the rear end 14A of the loading platform 14. The gate slider 18 is held at the upper limit position.
[0044]
First, the operator releases the lock mechanism 58 of the rear gate 26, operates the lift switch 68 to extend the cylinder mechanism 28, rotates the rear gate 26 rearward, and the road plate member 22 and the motorcycle mounting member 52 are The rotation of the rear gate 26 is stopped when the vehicle is in a state where it is slightly inclined upward from the horizontal.
[0045]
Here, the horizontal holding member 30 housed in the rear gate 26 is taken out, and the hooks 30B at both ends are engaged with the hooks 34B of the slider 34 and the hooks 56A of the rear gate 26.
[0046]
In this state, when the lift mechanism 68 is operated to slightly extend the cylinder mechanism 28 until the horizontal holding member 30 is tensioned, the road plate member 22 and the motorcycle mounting member 52 are substantially horizontal.
[0047]
Next, the lift switch 68 is operated, the cylinder mechanism 28 is contracted to raise the gate slider 18 slightly, and the movable member 42 of the movable stopper mechanism 40 is separated from the receiving member 50 upward. Here, the manual lever 48 is operated to retract the distal end portion 42 </ b> B of the movable member 42 against the urging force of the spring 44. Note that the retracted state of the movable member 42 is maintained by the cam mechanism 46.
[0048]
When the cylinder switch 28 is further extended by operating the lift switch 68 in this state, the gate slider 18 is lowered, and the rear gate 26 is in a state where the road plate member 22 and the motorcycle mounting member 52 are held in a substantially horizontal posture. Descend. When a part of the gate slider 18 or the rear gate 26 is grounded, the raising / lowering switch 68 is operated to stop the lowering of the rear gate 26. As a result, the road plate member 22 and the motorcycle mounting member 52 are brought into contact with or close to the ground 24 in a substantially horizontal posture.
[0049]
The worker pushes the transported motorcycle 20B by human power to get on the motorcycle mounting member 52 and places the stand of the transported motorcycle 20B so as to abut on the striped steel plate 52A (see FIG. 1). . Since the motorcycle mounting member 52 is in contact with or close to the ground 24 in a substantially horizontal posture, this operation is easy even when the transported motorcycle 20B is heavy.
[0050]
Next, after operating the manual lever 48 to project the tip 42B of the movable member 42, the lift switch 68 is operated to contract the cylinder mechanism 28 and raise the gate slider 18.
[0051]
When the distal end portion 42B comes into contact with the guide rail 16, the movable member 42 is guided to the inner peripheral surface of the guide rail 16 on the side surface and pulled against the urging force of the spring 44, and the gate slider 18 rises to the vicinity of the upper limit position. Then, the front end portion 42B of the movable member 42 re-projects. When the slide bar 36 comes into contact with the fixed stopper 38, the elevation switch 68 is operated to stop the ascent.
[0052]
Thereby, the motorcycle mounting member 52 is held in a substantially horizontal state and is raised to the vicinity of the rear end floor surface 14B of the loading platform 14.
[0053]
Here, the lift switch 68 is operated to slightly lower the gate slider 18 to bring the tip end portion 42B of the movable member 42 into contact with the receiving member 50.
[0054]
In this state, the operator manually pushes the transported motorcycle 20B and loads it onto the loading platform 14 from the on-vehicle mounting member 52. Since the on-vehicle mounting member 52 is held in a substantially horizontal state in the vicinity of the rear end floor surface 14C of the loading platform 14, this loading operation is easy even when the transported motorcycle 20B is heavy. Further, the transported motorcycle 20 </ b> B is mounted at a predetermined position on the loading platform 14.
[0055]
Next, the lift switch 68 is operated to slightly raise the gate slider 18, and the distal end portion 42 </ b> B of the movable member 42 is separated upward from the receiving member 50. Here, the manual lever 48 is operated to retract the movable member 42, and the lift switch 68 is further operated to lower the rear gate 26 until it contacts the ground 24.
[0056]
Thereafter, the loading operation of the transported motorcycle 20B is repeated in the same manner. After all the transported motorcycles 20B are mounted on the loading platform 14, these transported motorcycles 20B are secured to the loading platform 14. Further, with the gate slider 18 held at the upper limit position, the gate slider 18 is slightly rotated in the direction of the closed position so that the hooks 30B at both ends of the horizontal holding member 30 are moved from the hook 34B of the slider 34 and the hook 56A of the rear gate 26. The horizontal holding member 30 is removed and stored in a predetermined storage position of the rear gate 26.
[0057]
Further, the lift switch 68 is operated to rotate the gate slider 18 to the closed position and housed in the rear end 14 </ b> A of the loading platform 14, and fixed at the closed position by the lock mechanism 58.
[0058]
Thereby, the loading operation of the transported motorcycle 20B is completed, and the automobile transport vehicle 10 can travel. In the case of unloading, the unloading operation of the transported motorcycle 20B may be performed in the reverse procedure to the above using the horizontal holding and raising of the motorcycle mounting member 52.
[0059]
The rear gate 26 has a structure in which a motorcycle mounting member 52 is disposed between two road plate members 22, but the motorcycle mounting member 52 is shorter than the road plate member 22 and is expanded. The aerodynamic resistance is small because of the metal main structure. In addition, although a part of the motorcycle mounting member 52 is blocked by the striped steel plate 52A, the influence is small because the blocked region is limited to a part.
[0060]
Next, the operation of the rear gate device 12 in the loading operation of the transported automobile 4A will be described.
[0061]
The operator first releases the lock mechanism 58 of the rear gate 26 in the closed position and then operates the lift switch 68 to extend the cylinder mechanism 28 so that the wheel 60 at the free end 22B of the road plate member 22 contacts the ground 24. Until the rear gate 26 is rotated backward.
[0062]
Next, the auxiliary road plate member 66 is manually folded back and placed on the ground 24 so as to be farthest rearward from the road plate member 22 (as long as the long hole 64A of the engagement member 64 allows).
[0063]
As shown in FIG. 10, the loading and unloading operations are normally performed when the transported automobile 4 </ b> A self-propels on the auxiliary road plate member 66 and the road plate member 22 in this state.
[0064]

[0073]
Here, the lift switch 68 is operated to slightly lower the gate slider 18 to bring the tip end portion 42B of the movable member 42 into contact with the receiving member 50.
[0074]
As the base end 22A of the road plate member 22 rises, the free end 22B of the road plate member 22 moves forward, but the wheel 60 rolls so that it does not slide on the ground, and the engagement member 64 Since the long hole 64A is provided, the auxiliary road plate member 66 does not move forward in conjunction with the forward movement of the free end 22B of the road plate member 22.
[0075]
After releasing the side brake of the transported automatic four-wheeled vehicle 20A, the transported automatic four-wheeled vehicle 20A is placed on the loading platform 14 by self-propelling and mounted on a predetermined position of the loading platform 14. Since the base end 22 </ b> A of the road plate member 22 is disposed in the vicinity of the rear end floor surface 14 </ b> C of the loading platform 14, the transported automobile 4 </ b> A can get into the loading platform 14 without interfering with it.
[0076]
Next, the lift switch 68 is operated to raise the gate slider 18 slightly,
The distal end portion 42 </ b> B of the movable member 42 is separated from the receiving member 50. In this state, the manual lever 48 is operated to retract the movable member 42, and the lift switch 68 is further operated to lower the base end 22 </ b> A of the road plate member 22 to the vicinity of the ground 24.
[0077]
Thereafter, the loading operation of the transported automobile 4A is similarly repeated. When the loading of all the transported automatic four-wheeled vehicles 20 </ b> A to the loading platform 14 is completed, the mounted transported four-wheeled vehicles 20 </ b> A are secured to the loading platform 14.
[0078]
Further, with the gate slider 18 held at the upper limit position, the lift switch 68 is operated to rotate the gate slider 18 to the closed position and house it in the rear end 14A of the cargo bed 14, and the lock mechanism 58 holds it at the closed position. Fix it.
[0079]
As a result, the loading operation of the transported automatic four-wheeled vehicle 20A is completed, and the automobile transport vehicle 10 can travel.
