【０００１】
【発明の属する技術分野】
この発明は、車載用車両移動支援装置に関するもので、更に詳細には、車載用自動車の荷台の後端部に装着されて、荷台と地面に架け渡されて車両の積み下ろしを支援する車載用車両移動支援装置に関するものである。
【０００２】
【従来の技術】
従来、この種の車載用車両移動支援装置として、移動支援の対象となる車両例えば自動車のトレッド幅（自動車の左右のタイヤの中心から中心の距離）に合わせて平行に配備された一対の（２組の）車両移動支援板を、車載用自動車の荷台の後端部に起倒可能かつ荷台に対して略垂直位置に固定可能に装着した構造が知られている。
【０００３】
従来の車載用車両移動支援装置の主要部を構成する車両移動支援板は、両側部を形成するアルミニウム合金製の２本のパイプと、これらのパイプ間に架け渡して溶接によって一体的に固着された滑り止め機能を有するアルミニウム合金製のエキスパンドメタルとで構成されている（例えば、特許文献１参照）。
【０００４】
【特許文献１】
特開２００１−８９０８７（段落番号００３４，００４１、図１）
【０００５】
【発明が解決しようとする課題】
しかしながら、従来のこの種の車載用車両移動支援装置は、アルミニウム合金製の複数のエキスパンドメタル構成要素をパイプの長手方向に所定の間隔をあけて縦列配備すると共に、溶接によって固着することによりエキスパンドメタルを構成するため、多くの構成部材を要すると共に、組み立てに手間を要するという問題があった。
【０００６】
この発明は、上記事情に鑑みなされたもので、構成部材の削減が図れると共に、溶接部を少なくして組立を容易にした軽量で強度に富む車載用車両移動支援装置を提供することを目的とするものである。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、この発明の車載用車両移動支援装置は、車載用自動車の荷台の後端部に起倒可能かつ荷台に対して略垂直位置に固定可能に装着される一対の車両移動支援板を具備し、使用時において、上記車両移動支援板が上記荷台と地面に架け渡されて車両の積み下ろしを支援する車載用車両移動支援装置を前提とし、上記車両移動支援板は、それぞれ、表面部に多数の滑り止め突起を有する略矩形状の床板部と、この床板部の一側端の長手方向に沿う中空状補強枠と、床板部の他側端に形成される係合部とからなるアルミニウム合金製押出形材にて形成される一対の支援板半体を具備し、上記両支援板半体の係合部に嵌合されるアルミニウム合金製押出形材にて形成される固定部材をもって連結してなる、ことを前提とする。
【０００８】
請求項１記載の発明は、上記係合部は、一方の上記支援板半体の側端面に突設される一対の第１の係合突起と、他方の上記支援板半体の側端面に突設され、上記一対の第１の係合突起にテーパ面を介して噛合する一対の第２の係合突起とで構成されると共に、上記第１の係合突起の下方側の係合突起と上記第２の係合突起の上方側の係合突起は、上記支援板半体の側端面に対して直交状に突出されると共に、先端から対向する側に折曲される折曲片の内側面に傾斜受け面が形成され、かつ、上記第１の係合突起の上方側の係合突起と上記第２の係合突起の下方側の係合突起には、上記傾斜受け面に接触する傾斜面を有する折曲片が設けられ、かつ、これら係合突起の対向する面は互いに平行な傾斜面が形成され、上記固定部材は、上記係合部の上記第１の係合突起と上記第２の係合突起とを係合させた際に形成される、上記支援板半体の側端面と上記下方側の第１の係合突起及び上記上方側の第２の係合突起で区画される平行四辺形状の空間部内に挿入される輪郭が略平行四辺形の中空状基部と、この中空状基部の表面に適宜間隔をおいて突設され、上記空間部の内周面に接触可能な複数の突条を具備してなる、ことを特徴とする。
【０００９】
また、請求項２記載の発明は、上記係合部は、上記支援板半体の側端部に形成される中空状補助補強枠の上部内方側に長手方向に沿って溝状に形成され、上記固定部材は、上記両支援板半体を当接係合した状態で、上記両係合部内に挿入可能な一対の嵌合片と、この一対の嵌合片を開口側両端に有する断面略チャンネル状の固定部材本体と、上記固定部材本体の内周面に適宜間隔をおいて突設され、上記中空状補助補強枠の外周面に接触可能な互いに平行な複数の突条を具備してなる、ことを特徴とする。
【００１０】
請求項１，２記載の発明によれば、車両移動支援板は、表面部に多数の滑り止め突起を有する略矩形状の床板部の一側端の長手方向に沿う中空状補強枠を有し、他側端に係合部を有するアルミニウム合金製押出形材にて形成される一対の支援板半体を具備し、両支援板半体の係合部に嵌合されるアルミニウム合金製押出形材にて形成される固定部材をもって連結してなるので、溶接等の固定手段を用いることなく補強枠を一体に形成した車両移動支援板を形成することができる。
【００１１】
また、固定部材が支援板半体に接触可能な複数の突条を具備することで、固定部材をもって両支援板半体を連結する際、支援板半体との接触面積を小さくすることができるので、固定部材の挿入（嵌合）を容易にすることができる。
【００１２】
【発明の実施形態】
以下に、この発明に係る車載用車両移動支援装置について、添付図面に基づいて詳細に説明する。
【００１３】
◎第一実施形態
図１は、この発明に係る車載用車両移動支援装置の第一実施形態の要部を示す正面図（ａ）及び側面図（ｂ）、図２は、この発明における車両移動支援板を示す断面図である。
【００１４】
上記車載用車両移動支援装置１は、図６及び図７に示すように、車載用自動車であるトレーラ２の荷台３の後端部に起倒可能かつ荷台３に対して略垂直位置に固定可能に装着される一対の車両移動支援板１０を具備し、使用時において、車両移動支援板１０が荷台３と地面４に架け渡されて、移動支援の対象となる車両の積み下ろしを支援し、不使用時において、車両移動支援板１０が荷台３に対して略垂直位置（縦位置）に固定されるように構成されている。
【００１５】
この場合、上記車両移動支援板１０は、移動支援の対象となる車両のトレッド幅に対応した間隔をおいて平行に配設されて、トレーラ２の荷台３の後端部にヒンジ５をもって揺動可能に装着されるアルミニウム合金製押出形材にて形成される横フレーム６に溶接等の固定手段によって固定されている。また、両車両移動支援板１０間の荷台３側には補助連結板２０が連結されている。この補助連結板２０の一側部は横フレーム６に溶接等の固定手段によって固定され、また、他側部は両車両移動支援板１０間に架設されて溶接等の固定手段によって固定されるアルミニウム合金製押出形材にて形成される補助横フレーム６ａに溶接等の固定手段によって固定されている。この補助連結板２０は、車両移動支援板１０の長手方向の長さに対して約半分の長さに形成されている。また、両車両移動支援板１０の外側における荷台３側には、アルミニウム合金製押出形材にて形成される補強部材７とアルミニウム合金製パイプにて形成される把手８が固定されている。補強部材７には、荷台３に揺動自在に取り付けられたステー９が係脱可能に係合され、ステー９によって跳ね上げられた車両移動支援板１０が荷台３に対して略垂直位置に固定されるようになっている。この場合、車両移動支援板１０に対して補助連結板２０は約半分であるので、補助連結板２０の上方に空間部２１が形成され、この空間部２１から運転者は後方を確認することができる。
【００１６】
上記車両移動支援板１０は、図１及び図２に示すように、それぞれ、表面部に多数の滑り止め突起１１を有する略矩形状の床板部１２と、この床板部１２の一側端の長手方向に沿う断面矩形状の中空状補強枠１３と、床板部１２の他側端に形成される係合部１４とからなるアルミニウム合金製押出形材にて形成される一対の支援板半体１５を具備し、両支援板半体１５の係合部１４同士を係合させると共に、係合部１４に嵌合される固定部材１６（固定手段）をもって連結されている。
【００１７】
上記支援板半体１５は、図２に示すように、係合部１４を設けた側端に、長手方向に沿う断面矩形状の中空状補助補強枠１７を形成すると共に、この中空状補助補強枠１７と中空状補強枠１３との間に、これら補強枠１３，１７と平行な断面略逆Ｔ字状の補強リブ１８を形成してなる。この場合、中空状補強枠１３、中空状補助補強枠１７及び補強リブ１８の高さは同一に形成されている。このように、支援板半体１５に、長手方向に沿う互いに平行な中空状補強枠１３、中空状補助補強枠１７及び補強リブ１８を形成することによって、支援板半体１５自体の強度を向上させることができる。
【００１８】
また、滑り止め突起１１は、図１及び図３に示すように、プレス加工等によって打ち抜かれて形成され、上端に向かって狭小のテーパ状に隆起する突起孔１１Ａにて形成され、この突起孔１１Ａを多数非整列例えば千鳥状に配列してなる。また、床板部１２における突起孔１１Ａが形成されていない部分には、水抜き孔３０が形成されている。このように、多数の突起孔１１Ａを千鳥状に配列して設けることにより、積み下ろしされる車両の移動の際の長手方向及び短手方向のスリップを防止することができる。また、突起孔１１Ａが形成されていない部分に水抜き孔３０を形成することにより、床板部１２の表面に溜まる雨水等を水抜き孔３０から下方に排水することができるので、床板部表面にスリップの原因となる水膜が形成されるのを防止することができる。したがって、車両の積み下ろし作業を安全に行うことができる。
【００１９】
なお、上記実施形態では、多数の突起孔１１Ａが千鳥状に配列される場合について説明したが、突起孔１１Ａの配列形態は必ずしも千鳥状である必要はなく、非整列に配列されるものであれば、例えば散点状に多数の突起孔１１Ａを配列してもよい。
【００２０】
上記係合部１４は、一方の支援板半体１５の側端面に突設される一対の第１の係合突起４１ａ，４１ｂと、他方の支援板半体１５の側端面に突設され、一対の第１の係合突起４１ａ，４１ｂにテーパ面を介して噛合する一対の第２の係合突起４２ａ，４２ｂとで構成されている。この場合、第１の係合突起４１ａ，４１ｂの下方側の係合突起４１ｂと第２の係合突起４２ａ，４２ｂの上方側の係合突起４２ａは、側端面に対して直交状に突出されると共に、先端から対向する側に折曲される折曲片４１ｃ，４２ｃの内側面に傾斜受け面４３が形成されている。また、第１の係合突起４１ａ，４１ｂの上方側の係合突起４１ａと第２の係合突起４２ａ，４２ｂの下方側の係合突起４２ｂには、上記傾斜受け面４３に接触する傾斜面４４を有する折曲片４１ｄ，４２ｄが設けられており、かつ、これら係合突起４１ａと４２ｂの対向する面は互いに平行な傾斜面４５，４５が形成されている。
【００２１】
また、固定部材１６は、上記のように構成される係合部１４の第１の係合突起４１ａ，４１ｂと第２の係合突起４２ａ，４２ｂとを係合（噛合）させた際に形成される、支援板半体１５の側端面と第１の係合突起４１ｂ及び第２の係合突起４２ａで区画される平行四辺形状の空間部４６内に挿入されるアルミニウム合金製押出形材にて形成される輪郭が略平行四辺形の中空状基部１６ａの表面に適宜間隔をおいて突設される複数の突条１６ｂを具備している（図４参照）。このように、中空状基部１６ａの表面に適宜間隔をおいて複数の突条１６ｂを突設することにより、空間部４６内へ挿入される固定部材１６と、空間部４６を構成する支援板半体１５の側端面や傾斜面４５との接触面積を小さくすることができ、固定部材１６の挿入（嵌合）を容易にすることができる。
【００２２】
上記のように形成される、固定部材１６を用いて両支援板半体１５を連結するには、まず、両支援板半体１５の係合部１４同士すなわち第１の係合突起４１ａ，４１ｂと第２の係合突起４２ａ，４２ｂとを係合させる。この状態で、支援板半体１５の側端面と第１の係合突起４１ｂ及び第２の係合突起４２ａで区画される平行四辺形状の空間部４６が形成される。この空間部４６内に固定部材１６を挿入（嵌合）すると、第１の係合突起４１ａ，４１ｂと第２の係合突起４２ａ，４２ｂの傾斜面４５，４５が固定部材１６で押され、それぞれの折曲片４１ｄ，４２ｄが楔状に嵌り込んで、両支援板半体１５が強固に連結される。
【００２３】
上記実施形態では、支援板半体１５の側端面と第１の係合突起４１ｂ及び第２の係合突起４２ａで区画される平行四辺形状の空間部４６内に固定部材１６を挿入（嵌合）することで、両支援板半体１５同士を連結する場合について説明したが、支援板半体１５の連結形態は、必ずしもこの構造に限定されるものではない。
【００２４】
例えば、図５に示すように、支援板半体１５の側端部に形成された中空状補助補強枠１７の上部内方側に長手方向に沿って溝状の係合部１４Ａを形成し、両支援板半体１５を当接係合した状態で、両係合部１４Ａ内に挿入（嵌合）する一対の嵌合片１６ｄを有する断面略チャンネル状の固定部材１６Ａを用いて両支援板半体１５同士を連結することができる。この場合、固定部材１６Ａは、アルミニウム合金製押出形材にて形成され、断面略チャンネル状の固定部材本体１６ｃと、この固定部材本体１６ｃの開口側両端部からそれぞれ内向きに折曲される一対の嵌合片１６ｄと、固定部材本体１６ｃの内周面に適宜間隔をおいて突設される互いに平行な複数の突条１６ｅとで構成されている。このように、固定部材本体１６ｃの内周面に適宜間隔をおいて互いに平行な複数の突条１６ｅを突設することにより、固定部材１６Ａと補助補強枠１７の外周面との接触面積を小さくすることができるので、固定部材１６Ａの挿入（嵌合）を容易にすることができる。
【００２５】
上記のようにして形成される車両移動支援板１０の先端部には、楔状の側断面を有するアプローチプレート５０が溶接等の固定手段によって固着されている。
【００２６】
このアプローチプレート５０は、アルミニウム合金製押出形材にて形成されており、その上下面には、押出成形の過程で一体に加工された互いに平行な複数の滑り止め用突条５１が突設され、また、その内部には、複数例えば２本の補強用リブ５２が設けられて、上下方向の荷重に対して十分な強度が得られるようになっている（図１（ｂ）参照）。
【００２７】
また、上記補助連結板２０は、上記車両移動支援板１０における支援板半体１５に代えて同様の構造を有する連結板半体２２を用いる以外は車両移動支援板１０と同様に構成されている。すなわち、補助連結板２０は、それぞれ、表面部に多数の滑り止め突起１１を有する略矩形状の床板部１２と、この床板部１２の一側端の長手方向に沿う断面矩形状の中空状補強枠１３と、床板部１２の他側端に形成される係合部（図示せず）とからなるアルミニウム合金製押出形材にて形成される一対の連結板半体２２を具備し、両連結板半体２２の係合部同士を係合させると共に、係合部に嵌合される図示しない固定部材（固定手段）をもって連結されている。
【００２８】
なお、補助連結板２０において、滑り止め突起１１、係合部及び固定部材は、車両移動支援板１０と同様であるので、ここでは説明は省略する。
【００２９】
このように構成される補助連結板２０によれば、多数の滑り止め突起を形成することにより、車両の積み下ろし作業の際に、作業者が補助連結板を利用して荷台への上り下りを安全にすることができる。
【００３０】
上記のように構成される車載用車両移動支援装置１は、不使用時には、図６に示すように、車両移動支援板１０を跳ね上げた状態で、ステー９を補強部材７に係合させて、車両移動支援板１０をトレーラ２の荷台３に対して略垂直位置に固定する。この状態においては、上述したように、補助連結板２０の上方に空間部２１が形成されるので、この空間部２１から運転者は後方を確認することができる。
【００３１】
また、車載用車両移動支援装置１は、使用時には、図７に示すように、ステー９と補強部材７との係合を解いて、ヒンジ５を介して車両移動支援板１０を地面４側に倒して、車両移動支援板１０を荷台３と地面４に架け渡して、車両の積み下ろしを行うことができる。なお、図示しないが、車両の積み下ろしの際、荷台３の後端部が地面４に近い位置まで傾斜するようになっており、車両移動支援板１０の傾斜角度は緩やかになる。
【００３２】
◎第二実施形態
図８は、この発明に係る車載用車両移動支援装置の第二実施形態の要部を示す正面図、図９は、第二実施形態における車両移動支援板を示す断面図である。
【００３３】
第二実施形態は、滑り止め突起１１を、プレス加工等によって打ち抜かれて形成され、荷台３側に向かって拡開する開口部１１ａを有する膨隆突起１１Ｂにて形成した場合である。この場合、膨隆突起１１Ｂは、長手方向及び短手方向に整列された状態に配列されており、各膨隆突起１１Ｂは、図１０に示すように、プレス加工等によって打ち抜かれる過程で床板部１２に形成される水抜き孔１１ｂと開口部１１ａ以外を覆う袋状に形成されており、かつ、膨隆突起１１Ｂの基端から開口部１１ａに向かって拡開角度θ（例えば約３０°）が設けられている（図１０（ｃ）参照）。
【００３４】
このように、床板部１２の表面部に、荷台３側に向かって拡開する開口部１１ａを有する多数の膨隆突起１１Ｂを設けることにより、車載用車両移動支援装置１の使用時において、膨隆突起１１Ｂの開口部１１ａが荷台３側に向かって拡開角度θ（例えば約３０°）で隆起するので、積み下ろしされる車両の移動の際の長手方向及び短手方向のスリップを防止することができる。また、膨隆突起１１Ｂには水抜き孔１１ｂが形成されているので、床板部１２の表面にスリップの原因となる雨水等の水膜が形成されるのを防止することができる。したがって、車両の積み下ろし作業を安全に行うことができる。
【００３５】
なお、上記実施形態では、多数の膨隆突起１１Ｂを長手方向及び短手方向に整列した状態に配列する場合について説明したが、膨隆突起１１Ｂの配列形態は、これに限定されるものではなく、例えば、図１１に示すように、膨隆突起１１Ｂを千鳥状に配列してもよい。
【００３６】
また、第二実施形態において、補助連結板２０は、表面部に多数の膨隆突起１１Ｂ（滑り止め突起１１）を有する支援板半体１５と同様の多数の膨隆突起１１Ｂ（滑り止め突起１１）を有する連結板半体２２を具備する以外は、第一実施形態と同様に形成されており、床板部１２の一側端の長手方向に沿う断面矩形状の中空状補強枠１３と、床板部１２の他側端に形成される係合部（図示せず）とからなるアルミニウム合金製押出形材にて形成される一対の連結板半体２２を具備し、両連結板半体２２の係合部同士を係合させると共に、係合部に嵌合される図示しない固定部材（固定手段）をもって連結されている。
【００３７】
また、第二実施形態において、その他の部分は第一実施形態と同様であるので、同一部分には同一符号を付して、説明は省略する。
【００３８】
◎その他の実施形態
上記第一及び第二実施形態では、中空状補強枠１３が、断面矩形状に形成される場合について説明したが、図１２（ａ）に示すように、中空状補強枠１３の外方上端面に補強リブ６０を立設するようにしてもよい。このように、中空状補強枠１３の外方上端面に補強リブ６０を立設することにより、支援板半体１５自体に更に強度をもたせることができ、車両移動支援板１０の強度を更に向上させることができる。
【００３９】
また、中空状補強枠１３を、図１２（ｂ）に示すように、外側壁１３ａが開口する断面略Ｃ字状の中空状補強枠１３Ａにて形成してもよい。この場合、中空状補強枠１３Ａを構成する上部壁１３ｂ、下部壁１３ｃ、内側壁１３ｄ及び外側壁１３ａの肉厚を、支援板半体１５の肉厚より厚くする方が好ましい。このように、支援板半体１５に断面略Ｃ字状の中空状補強枠１３Ａを設けることにより、支援板半体１５の押出成形を容易にすることができる。
【００４０】
【発明の効果】
以上に説明したように、この発明の車載用車両移動支援装置は、上記のように構成されているので、以下のような効果が得られる。
【００４１】
（１）請求項１，２記載の発明によれば、車両移動支援板は、表面部に多数の滑り止め突起を有する略矩形状の床板部の一側端の長手方向に沿う中空状補強枠を有し、他側端に係合部を有するアルミニウム合金製押出形材にて形成される一対の支援板半体を具備し、両支援板半体の係合部に嵌合されるアルミニウム合金製押出形材にて形成される固定部材をもって連結してなるので、溶接等の固定手段を用いることなく補強枠を一体に形成した車両移動支援板を形成することができる。したがって、構成部材の削減が図れると共に、溶接等の固定手段を少なくして組み立て作業を容易にすることができ、かつ、軽量で強度に富む車載用車両移動支援装置を得ることができる。
【００４２】
（２）また、固定部材が支援板半体に接触可能な複数の突条を具備することで、固定部材をもって両支援板半体を連結する際、支援板半体との接触面積を小さくすることができるので、固定部材の挿入（嵌合）を容易にすることができる。
