Abstract
Description
特許文献2には、外面側に金属性の平板、波板及び平板からなる積層構造体を配し、内面側に衝撃吸収能を有する板材を配したトラックのアオリが記載されている。
よって、フロア部材の押出方向の途中にリブを設けることができず、必要のない部位(例えば、押出方向の前部)にリブを形成しなければならない。
また、押出方向に交差する方向にリブを設けることができず、剛性及び強度を高める必要のある部位にリブを設けることができない。
しかしながら、特許文献2に記載の装置は、トラックのアオリを用途として考案されており、必要な部位を補強するという課題がない。例えば、特許文献2に記載の積層構造体を補強してスロープに用いる際、波板の一部を切り欠いてコア材(骨材など)を介在させることが考えられる。しかし、波板を切り欠くことで、コア材とこのコア材の周縁部の波板との境界部分において強度及び剛性が低下してしまうという課題がある。
このような構成によれば、骨材の突出部を面板の端末に突き当てて係止することで、積層パネルの面板に対する骨材の位置決めをすることができ、組付け性を高めることができる。また、骨材を高い精度で位置決めすることができるようになり、剛性及び強度が要求される部位に、高い精度で骨材を配置することができる。
このような構成によれば、突出部が面板の板厚よりも厚いと、面板の表面側(コアパネルに対向する面と反対側の面)から突出してしまい、荷重を受けた際に面板ではなく突出部に先に荷重が入力されることとなる。これにより突出部に応力が集中してしまう。突出部を面板の板厚よりも小さく設定することで、突出部が面板の表面側に飛び出さないように設定し、荷重を面板で分散して受けることができ、応力集中を抑制することができる。また、積層パネルの端末をレールで挟持する場合にも突出部が邪魔にならないため、レールの挟持部によって面板を確実に挟持することができる。
このような構成によれば、矩形断面部から露出する露出部に部品取付部を備えることで、種々部品を取り付けたり、あるいは積層パネル自体を車体部品等に取付けることができ、積層パネルの有用性を向上させることができる。
このような構成によれば、露出部をヒンジ部とすることで、例えば積層パネルをスロープの荷台として使う際に、スロープに簡単にヒンジ部を設けることができ、積層パネルの有用性を向上させることができる。また、部品取付部を設けることで、積層パネルの部品を取り付けたり、積層パネルを車体等に取り付けることができる。
このような構成によれば、ヒンジ部と凹部の断面形状を湾曲断面形状とすることで、互いの隙間を小さくし、指や異物が挟みこまれることを抑制できる。
このような構成によれば、異物混入防止手段として、ゴム製のシール部材やブラシを備えることで、異物が混入することをより確実に防止することができる。
このような構成によれば、例えば積層パネルのスロープに用いる場合に、この傾斜面部によって積層パネルと接地面との間の段差を小さくして、被搭載物(例えば車椅子)の搭載性を向上させることができる。
このような構成によれば、積層パネルを介して骨材に伝達された荷重を、端末被覆部材(例えばレール)にも伝達させて荷重分散することができ、積層パネルの剛性及び強度を向上させることができる。
このような構成によれば、骨材を面板に対して結合(接合、接着、締結を含む)することで、面板に対する骨材の位置ズレを抑制することができ、剛性及び強度が要求される部位に、骨材を固定することができる。
このような構成によれば、挟持部、骨材部、コアパネル乃至面板へ向けて、段階的に剛性を変化させることにより、応力を分散させることができ、局所的に集中する応力を小さくすることができる。
このような構成によれば、積層パネルに、面直交方向の荷重が入力されると、荷台となる面に圧縮応力が加わり、反対側の面には引張応力が加わる。面板は、一般的に圧縮応力よりも引張応力に対する耐力が低いため、コアパネルの平坦部(例えばフランジ)を引張応力が加わる面板と骨材との間に挟持することで、引張応力に対する耐力を向上させることができる。
本発明の実施形態について、図面を参照して詳細に説明する。説明において、同一の要素には同一の符号を付し、重複する説明は省略する。なお、本発明の実施形態では、「前」は車両の進行方向側、「後」は車両の後退方向側、「上」は鉛直上方側、「下」は鉛直下方側、「左右」は車幅方向側とする。
車両本体2の後部の車室内には、スロープ50が設けられている。スロープ50は、未使用時(図1破線参照)には、バックドア3近傍に立設した状態で収納され、使用時には、車体後部開口5から車両1の後方に倒されて展開される。なお、スロープ50は、未使用時(図1破線参照)には、車室側に倒されてリアフロア6上に載置された状態で収容されることも可能である。また、未使用時の立設された状態において、スロープ50は、図示しないロック装置によって車体後部開口5の左右側辺に固定可能である。
第一スロープ51は、下段のスロープであり、スロープ本体であるプレート51aと、プレート51aの左右側辺に設けられたレール51b,51bと、を備える。第二スロープ52は、上段のスロープであり、スロープ本体であるプレート52aと、プレート52aの左右側辺に設けられたレール52b,52bと、を備える。
図2に示すように、レール52bの外側に形成された凸部52b1は、第一スロープ51のレール51bに形成された凹部51b1にスライド可能に嵌合されている。なお、スロープ50を構成する積層パネル100の構成については図3及び図4により後記する。
利用者は、使用時には、車両1の背面のバックドア3を開け、スロープ50の第一スロープ51及び第二スロープ52を車両後方に順次スライドした後に展開して路面等に据え置くようにする。スロープ50を展開した状態で、スロープ50は、所定の傾斜角の坂を構成する。
図3及び図4に示すように、積層パネル100は、パネル面に対して交差方向に延びる縦壁部111と、縦壁部111の端部111aからパネル面に沿って延びるように形成されたフランジ112(請求項1に記載の平坦部)とを有するコアパネル110と、コアパネル110を両面から挟む一対の面板120(121,122)と、コアパネル110のフランジ112を一方の面板121(120)との間で挟持する矩形断面部130aが配置された骨材130と、を主に備える。すなわち、他方の面板122(120)側から見ると、積層パネル100は、コアパネル110のフランジ112と他方の面板122との間に、矩形断面部130aを有する骨材130を配置した構成となっている。
また、積層パネル100の端末は、端末被覆部材140の挟持部142に挟持されて、当該端部が補強される。
積層パネル100は、例えばスロープ50(図1参照)の第二スロープ52に用いることができる。
コアパネル110は、例えばアルミ合金冷間プレス材からなる。コアパネル110は、一対の面板120(121,122)に対して交差方向に延びる縦壁部111と、縦壁部111の端部111aから一方の面板121に沿って延びるように形成され、面板121に当接されるフランジ112(平坦部)と、一方の面板121に沿って延びるように形成された第1平坦部113と、縦壁部111の一端同士と第1平坦部113とを繋ぐ第1折返し部111bと、他方の面板122に沿って延びるように形成された第2平坦部114と、縦壁部111の他端同士と第2平坦部114とを繋ぐ第2折返し部111cと、を備える。
すなわち、コアパネル110は、縦壁部111の端部111aから一方の面板121に沿って延びるように形成された平坦部を構成するフランジ112と、第1折返し部111bから一方の面板121に沿って延びるように形成された第1平坦部113と、第2折返し部111cから他方の面板122に沿って延びるように形成された第2平坦部114と、を備え、図4に示すように、縦壁部111と第1平坦部113と第2平坦部114の部分が、断面視で台形形状が連続する波板となっている。
面板120は、例えばアルミ合金板材からなる。面板120は、コアパネル110を下面から挟む一方の面板121と、コアパネル110を上面から挟む他方の面板122と、からなる。一方の面板121と他方の面板122とは、積層パネル100の左右方向(幅方向)の形状及び寸法が同じであればよく、上下方向の長さや厚さ、材質などは互いに異なるものでもよい。但し、一方の面板121と他方の面板122とを同一部材とすると、調達コストの低減と作業性の向上が期待できる。
骨材130は、積層パネル100の対応部位を補強するための補強部材である。骨材130は、一対の面板120(121,122)の間に、コアパネル110のフランジ112を一方の面板121との間で挟持するように配置される。より具体的には、骨材130は、フランジ112と他方の面板122との間に配置されて、一対の面板120(121,122)に対して結合される。
なお、本発明の「結合」とは、接着、締結、又は接合のいずれかを含む概念である。図10により後記する。
骨材130は、例えば中空のアルミ合金押出材からなる角パイプである。骨材130は、中実であってもよく、また矩形断面はどのような断面形状でもよい。また、骨材130は、積層パネル100の対応部位を補強するものであるため、当該対応部位に応じた配置、形状及び長さを有している。
図4に示すように、積層パネル100は、コアパネル110と一対の面板120(121,122)と骨材130とが接着剤150により接合(接着)され、一体化される。具体的には、積層パネル100は、骨材130の断面部130aとコアパネル110のフランジ112の上面との間、フランジ112の底面と一方の面板121との間、コアパネル110の第1平坦部113と一方の面板121との間、骨材130と他方の面板122との間、コアパネル110の第2平坦部114と他方の面板122との間がそれぞれ接着剤150により接合される。
本実施形態では、積層パネル100の端末を被覆する端末被覆部材の一例として端末被覆部材140を用いている。端末被覆部材140は、積層パネル100を一定方向に走らせるための棒状の部材であり、積層パネル100の端末を補強する機能に加え、当該端部の端面及び角部を保護する保護部材として機能する。
積層パネル100の端末は、端末被覆部材である端末被覆部材140の挟持部142に挟持される。
本実施形態では、端末被覆部材として端末被覆部材140を用いることで、例えばスロープ50(図1参照)に用いることができる。積層パネル100をスロープ50(図1参照)として用いる場合、端末被覆部材140は、スライド部の一部を構成している。例えば、積層パネル100が、第二スロープ52(図1参照)に用いられる場合、積層パネル100が、スロープ本体であるプレート52aに対応し、端末被覆部材140が、プレート52aの左右側辺に設けられたレール52b,52bに対応する。
[本実施形態と比較例との対比]
まず、本実施形態に係る積層パネルの比較例について説明する。
図5Aに示すように、比較例1の積層構造体100Aは、コア材である波板110Aと、波板110Aを両面(上下面)から挟む一対の面板120(121,122)と、積層構造体100Aを補強する骨材130と、を備える。骨材130は、波板110Aの一部(骨材130を配置するための部分)を切り欠いた切欠き部110A1に配置されている。
しかし、比較例1では、骨材130を波板110Aの切欠き部110A1に配置しているので、図5Aの破線丸印aに示すように、切欠き部110A1と骨材130との間は、一方の面板121のみが存在し、低強度や低剛性となっている。すなわち、図5Aの破線丸印aに示す部分では、切欠き部110A1と骨材130との間は、一方の面板121のみが存在し、積層構造体100Aの全体的な補強に寄与しないばかりか却って切欠き部110A1と骨材130との間で剪断的な応力が集中して変形の起点となってしまうおそれがある。
よって、本実施形態に係る積層パネル100は、比較例1(図5A)に比べて局所的に低強度や低剛性となる部位をなくすことができ、応力集中を抑制して積層パネル100の剛性及び強度を向上させることができる。
本実施形態に係る積層パネル100は、一対の面板120(121,122)で挟んだコアパネル110にフランジ112を設け、このフランジ112と他方の面板122との間に骨材130の矩形断面部130aを配置している。積層パネル100は、被搭載物を搭載可能とするパネル(例えば図1に示すスロープ50を構成するパネル)に適用する場合、被搭載物の搭載面にかかる力に対して図6に示すような圧縮応力及び引張応力が発生する。このため、本実施形態では、積層パネル100を載置する際、表面と裏面とが区別して使用される。
<骨材:矩形ブロック部品>
次に、本実施形態に係る積層パネルの骨材の変形例について説明する。
図7に示す積層パネル101は、積層パネル100の周縁(ここでは左右両端)に配置された骨材131を備える。
骨材131は、複数個の矩形ブロック部品であり、各矩形ブロック部品からなる骨材131は、矩形断面部131aを有する。骨材131を有する積層パネル101は、図3及び図4に示す積層パネル100と同様に、骨材131の矩形断面部131aと一方の面板121との間でコアパネル110のフランジ112を挟み込み、接着剤(図示省略)を介して接合する。
図8に示す積層パネル102は、積層パネル100の周縁(ここでは左右両端)に配置された骨材132を備える。
骨材132は、コアパネル110のフランジ112と一方の面板121との間に矩形断面部132aと、矩形断面部132から一方の面板121の面に交差する方向に突出して面板121の端末に当接することで係止される突出部132b1と、矩形断面部132から他方の面板122の面に交差する方向に突出して面板122の端末に当接することで係止される突出部132b2と、を備える。
骨材132を有する積層パネル102は、骨材130の矩形断面部131aと一方の面板121との間でコアパネル110のフランジ112を挟み込み、接着剤150を介して接合する。
突出部132b1は、突出部132b2よりも、骨材132の矩形断面部132aと一方の面板121との間でコアパネル110のフランジ112を挟み込む分だけ突出高さが長い。
図9の破線丸印dに示すように、骨材132の突出部132b1,132b2の突出高さは、それぞれ、一対の面板120(121,122)の板厚よりも小さく設定される。具体的には、骨材132の突出部132b1の突出高さは、一方の面板121の外表面までの長さよりも小さく設定される。このため、骨材132の突出部132b1が、一方の面板121の外表面121aを超えて突出しないので、この突出部132b1が端末被覆部材140の挟持部142の内壁に当接することはない。同様に、骨材132の突出部132b2の突出高さは、他方の面板122の外表面までの長さよりも小さく設定される。このため、骨材132の突出部132b2が、他方の面板122の外表面122aを超えて突出しないので、この突出部132b2が端末被覆部材140の挟持部142の内壁に当接することはない。
また、積層パネル102の端末を端末被覆部材140(図3参照)で挟持する場合にも突出部132b1,132b2が邪魔にならないため、端末被覆部材140の挟持部142によって面板120を確実に挟持することができる。
次に、骨材130と一対の面板120(121,122)との結合の例について説明する。本発明の「結合」とは、接着、締結、又は接合のいずれかを含む概念である。
図10は、摩擦撹拌接合(FSW:Friction Stir Welding)の例を説明する説明図である。
図10に示すように、接合の例として、骨材132を一対の面板120(121,122)に対して摩擦撹拌接合(FSW)により接合する。図10では、骨材132と一対の面板120(121,122)とコアパネル110のフランジ112との接着剤150による接着、かつFSW(図10の網掛け参照)を用いている。上記接着は、骨材132と一対の面板120(121,122)とコアパネル110のフランジ112との間に構造用接着剤150を介在させて接合する。
図11に示すように、骨材133は、コアパネル110のフランジ112と一方の面板121との間に矩形断面部133aと、矩形断面部133から一方の面板121の面に交差する方向に突出して面板121の端末に当接することで係止される突出部133b1と、矩形断面部133から他方の面板122の面に交差する方向に突出して面板122の端末に当接することで係止される突出部133b2と、骨材133の断面内に貫通する貫通孔133cと、を備える。
突出部133b1は、突出部133b2よりも、骨材133の矩形断面部133aと一方の面板121との間でコアパネル110のフランジ112を挟み込む分だけ突出高さが長い。
また、骨材133の貫通孔133cに対向する他方の面板122には、貫通孔122aが形成されている。なお、コアパネル110のフランジ112の長さは、骨材133の矩形断面部133の長さに対応している。
次に、骨材が一対の面板120(121,122)の端部から露出する例について説明する。骨材が一対の面板120(121,122)の端部から露出する例としては、例えば、(1)骨材が複数の積層パネル同士を回動自在に連結するヒンジ部を構成する場合、(2)骨材が一対の面板120(121,122)の端部に取り付ける傾斜板等の取付部品を構成する場合が挙げられる。
図12に示すように、積層パネル103,103は、面板120,120の上端部又は下端部から露出する骨材134,134を備える。骨材134,134は、後記するようにヒンジ部135を有し、積層パネル103,103は、ヒンジ部135を介して回動自在に連結される。上部の積層パネル103のヒンジ部135と下部の積層パネル103のヒンジ部135とは、ヒンジ部135同士が交互に組み合わされる。
図13には、図12に示す積層パネル103,103のうち、例えば図12の上部の積層パネル103が示されている。図13に示すように、積層パネル103は、パネル面に対して交差方向に延びる縦壁部111を有するコアパネル110と、コアパネル110を両面から挟む一対の面板120(121,122)と、一対の面板120(121,122)の端部から露出する骨材134と、を主に備える。
骨材134は、例えば中空のパイプからなり、コアパネル110のフランジ112と他方の面板122との間に配置された矩形断面部134aと、一対の面板120(121,122)の面に沿う方向に延び、かつ一対の面板120(121,122)の端部から当該端部を覆うように露出する露出部134bと、を備える。面板120(121,122)の端部と露出部134bとの接合部分は、段差がないように形成される。
以上の構成において、図12に示すように、上部の積層パネル103の骨材134の露出部134bであるヒンジ部135と、下部の積層パネル103の骨材134のヒンジ部135とを互いに組み合わし、組み合わせたヒンジ部135の貫通孔135aに軸部材(図示省略)連通させて、上部の積層パネル103と下部の積層パネル103とをヒンジ部135により回動自在に軸支する。
なお、上記ヒンジ部135とヒンジ部135以外の部品取付部とを1つ以上備えてもよい。また、骨材134の露出部134aの配置は、どのような箇所でもよい。換言すれば、骨材134の露出部134aを所望の箇所に配置するために、骨材134とコアパネル110のフランジ112(図13参照)の構成を決定する。
図15に示すように、骨材136が一対の面板120(121,122)の端部に取り付ける傾斜板等の取付部品であってもよい。
図15に示す積層パネル104は、スロープ50(図1参照)の下段のスロープに適用される。積層パネル104は、パネル面に対して交差方向に延びる縦壁部111を有するコアパネル110と、コアパネル110を両面から挟む一対の面板120(121,122)と、一対の面板120(121,122)の端部から露出する骨材136と、を主に備える。
骨材136は、例えば中空のパイプからなり、コアパネル110のフランジ112と他方の面板122との間に配置された矩形断面部136aと、一方の面板121の面に沿う方向に延び、かつ一対の面板120(121,122)の端部から露出する露出部136bと、を備える。露出部136bは、他方の面板122の端部から外側に延びる平坦部136cと、露出部136bの先端部から他方の平坦部136cの端部まで傾斜した傾斜面部136dと、を備える。面板120(121,122)の端部と露出部136bとの接合部分は、段差がないように形成される。
次に、積層パネルの骨材のヒンジ部の構造について説明する。
図16は、比較例の積層パネルの骨材のヒンジ部の説明図であり、図16Aはその平面図、図16Bはその側面図である。
図16に示すように、比較例の積層パネル1103,1103は、面板1120,1120の端部から露出する骨材1134,1134を備える。骨材1134,134は、ヒンジ部1135を有し、積層パネル1103,1103は、ヒンジ部1135を介して回動自在に連結される。一方の積層パネル1103のヒンジ部1135と他方の積層パネル1103のヒンジ部1135とは、ヒンジ部1135同士が交互に組み合わされる。組み合わせたヒンジ部1135の貫通孔1135aに軸部材(図示省略)連通させて、一方の積層パネル1103と他方の積層パネル1103とをヒンジ部1135により回動自在に軸支する。
しかしながら、比較例の積層パネル1103,1103のヒンジ構造では、図16の二点鎖線丸囲みに示すように、面板1120の端部と骨材1134の先端部との間に隙間が生じる。この隙間が大きい場合、隙間に指などを挟み込んだり、異物が混入する等の懸念がある。
図17に示すように、骨材137は、例えば中空のパイプからなり、コアパネル110(図4参照)のフランジ112(図4参照)と他方の面板122(図4参照)との間に配置された矩形断面部137aと、一対の面板120(図4参照)の面に沿う方向に延び、かつ一対の面板120の端部から当該端部を覆うように露出する露出部137bと、を備える。面板120の端部と露出部137bとの接合部分は、段差がないように形成される。
ヒンジ部138は、一方の積層パネル100(図4参照)と他方の積層パネル100とを回動可能に軸支する。ヒンジ部138の先端部138aは、断面視して、外方に凸の湾曲断面形状に形成されている。ヒンジ部138には、軸部材(図示省略)連通させる貫通孔138bが開孔されている。
凹部139は、他方の積層パネル100に接合された骨材137から突出した各ヒンジ部138の先端部138aを受容可能な湾曲断面形状に形成されている。
図18Aに示すように、本実施形態の積層パネル104,104は、面板120,120の端部から露出する骨材137,137を備える。図18に示すように、骨材137,137は、ヒンジ部138,138と、湾曲形状の凹部139と、を有する。一方の積層パネル104のヒンジ部138と他方の積層パネル104のヒンジ部138,138とを互いに組み合わし、組み合わせたヒンジ部138,138の貫通孔138aに軸部材(図示省略)連通させて、一方の積層パネル104と他方の積層パネル104とをヒンジ部138,138により回動自在に軸支する。
図19は、変形例の積層パネルの骨材のヒンジ部の説明図であり、図19Aはその平面図、図19Bはその側面図である。
図19Aに示すように、本実施形態の積層パネル105,105は、面板120,120の端部から露出する骨材237,237を備える。骨材237は、一対の面板120の面に沿う方向に延び、かつ一対の面板120の端部から当該端部を覆うように露出する露出部237bを備える。露出部237bは、骨材237の長手方向に沿って互いに所定距離離間した位置で複数形成されたヒンジ部238と、各ヒンジ部238の間に形成された凹部239と、を有する。
ヒンジ部238は、一方の積層パネル105と他方の積層パネル105とを回動可能に軸支する。ヒンジ部238は、断面視して、半円形状に形成されている。ヒンジ部238には、軸部材(図示省略)連通させる貫通孔238bが開孔されている。
凹部239は、他方の積層パネル105に接合された骨材237から突出した各ヒンジ部238の半円形状の先端部を受容可能な湾曲断面形状に形成されている。
なお、この変形例において、図18Bの場合と同様に、積層パネル105が、ヒンジ部238と凹部239との間に異物混入防止手段を備える構成を採るものでもよい。
次に、積層パネルの端末部補強構造について説明する。
図20A~Eは、本発明の実施形態に係る積層パネルの端末部補強構造を説明する断面図である。前記図4の積層パネル100の各部の寸法等を検討した場合を例に採る。なお、接着剤150の図示は省略している。また、積層パネル100の縁部及び端末被覆部材140は、ネジ151により締結されている。
まず、図20A~Dに示すように、積層パネル100A~100Dは、パネル面に対して交差方向に延びる縦壁部111と、縦壁部111の端部111aからパネル面に沿って延びるように形成されたフランジ112とを有するコアパネル110と、コアパネル110を両面から挟む一対の面板121,122と、コアパネル110のフランジ112を一方の面板121との間で挟持する矩形断面部130aが配置された骨材130A~130Dと、を備えている。また、積層パネル100A~Dの端末は、端末被覆部材140の挟持部142に挟持されて、当該端部が補強される。
図21及び図22に示すように、比較例Dの積層パネル100Dが、発生応力比が最も小さく端末部補強に優れているベストモードであることが判明した。比較例Dの積層パネル100Dは、積層パネルの縁部に直交する方向において、骨材130Dが、狭持部142よりも突出して形成されるものである。挟持部142の端面と骨材130Dの矩形断面部130aの端面との間の距離である寸法aは、10mmである。
このように、ベストモードである積層パネル100Dは、挟持部142から骨材部(骨材130D)、コアパネル110、さらに面板121,122へ向けて、段階的に剛性を変化させる構成を採ることにより、応力を分散させることができ、局所的に集中する応力を小さくすることができる。
