本発明は、横部材のねじれ剛性を向上させた金属製パレットに関する。
【０００２】
【従来の技術】
従来、積み荷用の平パレット、特に金属製パレット１としては、図９および図１０に示すように、長さ方向に沿って複数条の凹凸部４（ａ，ｂ）が形成された金属板メンバーＭ（１〜３）が設けられて、第１の金属板メンバーＭ１と第２の金属板メンバーＭ２とが長さ方向に所定の間隔を隔てて複数配置された脚部材５で上下方向に所定の間隔を隔てられた状態で、脚部材５と第１および第２の金属板メンバーＭ１，Ｍ２とが溶接で固定されてなる横部材２が複数並列（本例では３本）されるとともに、各横部材２の上側の第１の金属板メンバーＭ１の上面に、第３の金属板メンバーＭ３でなる縦部材３が長さ方向に所定の間隔を隔てて複数並列（本例では５本）されて、第３の金属板メンバーＭ３と第１の金属板メンバーＭ１とが溶接で固定されて構成されてなるものがある。
【０００３】
上記各金属板メンバーＭ（１〜３）は、第１の金属板メンバーＭ１のような上下向きの状態において、上向きの凸部４ｂと下向きの凹部４ａとが形成され、凸部４ｂには突出溝４ｄを有し、凹部４ａには没入溝４ｃを有している。
【０００４】
上記脚部材５は、チャンネル状に形成され、両側壁部５ａが第１および第２の金属板メンバーＭ１，Ｍ２の凹凸部４（ａ，ｂ）と平行する方向に配置されて、この両側壁部５ａの上部と下部に、幅方向の一側端と他側端の凸部４ｂの突出溝４ｄにそれぞれ嵌め込み可能な嵌め込み部５ｃ，５ｄが突出形成されている。
【０００５】
そして、脚部材５の両側壁部５ａを第１および第２の金属板メンバーＭ１，Ｍ２の凹凸部４（ａ，ｂ）と平行する方向として、一側の嵌め込み部５ｃを第１および第２の金属板メンバーＭ１，Ｍ２の一側端の凸部４ｂの突出溝４ｄにそれぞれ嵌め込み、他側の嵌め込み部５ｄを第１および第２の金属板メンバーＭ１，Ｍ２の他側端の凸部４ｂの突出溝４ｄにそれぞれ嵌め込むことにより、第１および第２の金属板メンバーＭ１，Ｍ２を脚部材５で上下方向に所定の間隔を隔てた状態に保持して、この状態で、脚部材５の両側壁部５ａと第１および第２の金属板メンバーＭ１，Ｍ２の両側部とを隅肉アーク溶接ａで固定することで、横部材２を製造し、ついで、複数並列した横部材２の上側の第１の金属板メンバーＭ１の上面に、第３の金属板メンバーＭ３でなる縦部材３を長さ方向に所定の間隔を隔てて複数並列して、この第３の金属板メンバーＭ３の両側部と第１の金属板メンバーＭ１の上壁（最外側部分では、第３の金属板メンバーＭ３の両側部と第１の金属板メンバーＭ１の端部と脚部材５の底壁部５ｂ）とを隅肉アーク溶接ｂで固定することで、金属製パレット１に組み立てていた（例えば、特許文献１参照）。
【０００６】
一方、図１１および図１２に示すように、別形態の脚部材５は、チャンネル状に形成され、両側壁部５ａが第１および第２の金属板メンバーＭ１，Ｍ２の凹凸部４（ａ，ｂ）と直交する方向に配置されて、底壁部５ｂ近傍の両側壁部５ａの根元と両側壁部５ａの先端とに、幅方向の一側端と他側端の凸部４ｂの突出溝４ｄにそれぞれ嵌め込み可能な嵌め込み部５ｃ，５ｄが突出形成されている。
【０００７】
そして、脚部材５の両側壁部５ａを第１および第２の金属板メンバーＭ１，Ｍ２の凹凸部４（ａ，ｂ）と直交する方向として、一側の嵌め込み部５ｃを第１および第２の金属板メンバーＭ１，Ｍ２の一側端の凸部４ｂの突出溝４ｄにそれぞれ嵌め込み、他側の嵌め込み部５ｄを第１および第２の金属板メンバーＭ１，Ｍ２の他側端の凸部４ｂの突出溝４ｄにそれぞれ嵌め込むことにより、第１および第２の金属板メンバーＭ１，Ｍ２を脚部材５で上下方向に所定の間隔を隔てた状態に保持して、この状態で、両側壁部５ａの上下端に形成したフランジ部５ｅと第１および第２の金属板メンバーＭ１，Ｍ２の凹部４ａの没入溝４ｃの底壁とをスポット溶接ｃで固定することで、横部材２を製造し、ついで、複数並列した横部材２の上側の第１の金属板メンバーＭ１の上面に、第３の金属板メンバーＭ３でなる縦部材３を長さ方向に所定の間隔を隔てて複数並列して、この第３の金属板メンバーＭ３の凹部４ａの没入溝４ｃの底壁と第１金属板メンバーＭ１の凸部４ｂの突出溝４ｄの底壁とをスポット溶接ｄで固定することで、金属製パレット１に組み立てていた（例えば、特許文献２参照）。

【発明が解決しようとする課題】
しかしながら、特許文献１の横部材２の脚部材５は、両側壁部５ａが第１および第２の金属板メンバーＭ１，Ｍ２の凹凸部４（ａ，ｂ）と平行する方向に配置されているものの、開口５ｆの部分と底壁部５ｂとは、第１および第２の金属板メンバーＭ１，Ｍ２とに固定されていないから、第１の金属板メンバーＭ１と第２の金属板メンバーＭ２とに、長さ方向に互いに逆向きの力が加わったときには、脚部材５が変形して、横部材２がねじれやすいという問題がある。
【００１０】
また、特許文献２の横部材２の脚部材５は、両側壁部５ａが第１および第２の金属板メンバーＭ１，Ｍ２の凹凸部４（ａ，ｂ）と直交する方向に配置されていて、側方に開口５ｆが位置するから、両側壁部５ａのフランジ部５ｅが第１および第２の金属板メンバーＭ１，Ｍ２に固定されているものの、第１の金属板メンバーＭ１と第２の金属板メンバーＭ２とに、長さ方向に互いに逆向きの力が加わったときには、脚部材５が変形して、横部材２がねじれやすいという問題がある。
【００１１】
本発明は、上記従来の問題を解決するためになされたもので、横部材のねじれ剛性を向上させた金属製パレットを提供することを目的とするものである。
【００１２】
【課題を解決するための手段】
上記課題を解決するために、本発明は、長さ方向に沿って複数条の凹凸部が形成された金属板メンバーが設けられて、第１の金属板メンバーと第２の金属板メンバーとが長さ方向に所定の間隔を隔てて複数配置された脚部材で上下方向に所定の間隔を隔てられた状態で、脚部材と第１および第２の金属板メンバーとが固定されてなる横部材が複数並列されるとともに、各横部材の上側の第１の金属板メンバーの上面に、第３の金属板メンバーでなる縦部材が長さ方向に所定の間隔を隔てて複数並列されて、第３の金属板メンバーと第１の金属板メンバーとが固定されて構成されてなる金属製パレットにおいて、
上記脚部材は、チャンネル状に形成され、両側壁部が第１および第２の金属板メンバーの凹凸部と平行する方向に配置されて、この両側壁部の上部と下部に、幅方向の一側端と他側端の凸部の突出溝にそれぞれ嵌め込み可能な嵌め込み部が突出形成されている一方、上記脚部材の底壁部の上下端に、第１および第２の金属板メンバーの凹部の没入溝の底壁に当接させて固定されるフランジ部がそれぞれ形成されているととともに、開口側の嵌め込み部から内向きに折り曲げられた前壁部がそれぞれ設けられて、この前壁部上下端に、第１および第２の金属板メンバーの凹部の没入溝の底壁に当接させて固定されるフランジ部がそれぞれ形成されていることを特徴とする金属製パレットを提供するものである。
【００１３】
請求項２のように、上記脚部材の両前壁部の前端は、開口を塞ぐように相互に突き合わせ若しくは重ね合わされて固定されている構成とすることが好ましい。
【００１４】
請求項３のように、上記脚部材のフランジ部は、外向きに突出形成されている構成とすることが好ましい。
【００１５】
請求項４のように、上記脚部材は、底壁部が第１および第２の金属板メンバーの端部において、外向きとなるように配置されている構成とすることが好ましい。
【００１６】
【発明の作用および効果】
本発明によれば、脚部材の両側壁部を第１および第２の金属板メンバーの凹凸部と平行する方向として、嵌め込み部を第１および第２の金属板メンバーの一側端と他側端の凸部の突出溝にそれぞれ嵌め込み、底壁部のフランジ部を第１および第２の金属板メンバーの凹部の没入溝の底壁に当接させて固定するとともに、前壁部のフランジ部を第１および第２の金属板メンバーの凹部の没入溝の底壁に当接させて固定することで、横部材を製造することができる。
【００１７】
したがって、脚部材の両側壁部を第１および第２の金属板メンバーの凹凸部と平行する方向としたことと相俟って、底壁部と前壁部のフランジ部を第１および第２の金属板メンバーに固定しているから、第１の金属板メンバーと第２の金属板メンバーとに、長さ方向に互いに逆方向の力が加わったときでも、脚部材が変形しにくくなって、横部材がねじれにくくなるので、横部材のねじれ剛性が向上するようになる。
【００１８】
また、底壁部と前壁部のフランジ部により、横部材の圧縮（座屈）強度も向上するようになる。
【００１９】
請求項２によれば、脚部材の前壁部の前端を、開口を塞ぐように相互に突き合わせ若しくは重ね合わせて固定すると、脚部材が平面視で閉断面を構成して強度が向上するので、横部材のねじれ剛性がより向上するようになる。
【００２０】
請求項３によれば、脚部材のフランジ部を外向きに突出形成しているので、第１および第２の金属板メンバーの底壁とのスポット溶接等による固定が容易に行える。
【００２１】
請求項４によれば、脚部材の底壁部が第１および第２の金属板メンバーの端部において、外向きとなるように配置しているので、外観性が良好になる。
【００２２】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して詳細に説明する。
【００２３】
図６および図７に示すように、金属製パレット１１は、従来と同様に、長さ方向に沿って複数条の凹凸部１４（ａ，ｂ）が形成された金属板メンバーＭ（１〜３）が設けられている。
【００２４】
第１の金属板メンバーＭ１と第２の金属板メンバーＭ２とが長さ方向に所定の間隔を隔てて複数配置された脚部材１５で上下方向に所定の間隔を隔てられた状態で、脚部材１５と第１および第２の金属板メンバーＭ１，Ｍ２とがスポット溶接ｃで固定されてなる横部材１２が複数並列（本例では３本）されている。
【００２５】
この各横部材１２の上側の第１の金属板メンバーＭ１の上面に、第３の金属板メンバーＭ３でなる縦部材１３が長さ方向に所定の間隔を隔てて複数並列（本例では５本）されて、第３の金属板メンバーＭ３と第１の金属板メンバーＭ１とがスポット溶接ｄ（図１参照）で固定されて構成されている。
【００２６】
上記各金属板メンバーＭ（１〜３）は、図８に示すような上下向きの状態において、上向きの凸部１４ｂと下向きの凹部１４ａとが幅方向に交互に形成され、凸部１４ｂには突出溝１４ｄを有し、凹部１４ａには没入溝１４ｃを有している。なお、第２の金属板メンバーＭ２は、第１および第３の金属板メンバーＭ１，３とは上下逆向きに配置されて凹凸部１４の向きも変わるが、凸部１４ｂと凹部１４ａおよび突出溝１４ｄと没入溝１４ｃの部分名称は第１および第３の金属板メンバーＭ１，３と同じに取り扱うこととする。
【００２７】
上記脚部材１５は、図１〜図４に示すように、チャンネル状に形成され、両側壁部１５ａが第１および第２の金属板メンバーＭ１，Ｍ２の凹凸部１４（ａ，ｂ）と平行する方向に配置されて、この両側壁部１５ａの上部と下部に、幅方向の一側端と他側端の凸部１４ｂの突出溝１４ｄにそれぞれ嵌め込み可能な嵌め込み部１５ｃ，１５ｄがそれぞれ突出形成されている。
【００２８】
上記脚部材５の底壁部１５ｂの上下端には、第１および第２の金属板メンバーＭ１，Ｍ２の２箇所の凹部１４ａの没入溝１４ｃの底壁に当接するフランジ部１５ｅがそれぞれ外向きに突出形成されている。
【００２９】
上記脚部材５の開口１５ｆ側の嵌め込み部１５ｃ，１５ｄから内向きに折り曲げられた前壁部１５ｇがそれぞれ設けられ、この前壁部１５ｇの上下端に、第１および第２の金属板メンバーＭ１，Ｍ２の２箇所の凹部１４ａの没入溝１４ｃの底壁に当接するフランジ部１５ｈがそれぞれ外向きに突出形成されている。
【００３０】
なお、底壁部１５ｂとフランジ部１５ｅのコーナー部分と、前壁部１５ｇとフランジ部１５ｈのコーナー部分とには、フランジ部１５ｅ，１５ｈの強度を上げるために打ち出した三角状補強リブ１５ｉがそれぞれ形成されている。
【００３１】
上記の各金属板メンバーＭ（１〜３）および脚部材１５を組み立てて金属製パレット１１を製造する方法を次に説明する。
【００３２】
第１の金属板メンバーと第２の金属板メンバーＭ１，Ｍ２との間に、長さ方向に所定の間隔を隔てて複数配置（本例では５個）した脚部材１５の両側壁部１５ａを、第１および第２の金属板メンバーＭ１，Ｍ２の凹凸部１４（ａ，ｂ）と平行する方向として、嵌め込み部１５ｃを第１および第２の金属板メンバーＭ１，Ｍ２の一側端の凸部１４ｂの突出溝１４ｄにそれぞれ嵌め込み、嵌め込み部１５ｄを第１および第２の金属板メンバーＭ１，Ｍ２の他側端の凸部１４ｂの突出溝１４ｄにそれぞれ嵌め込み、各フランジ部１５ｅ，１５ｈを第１および第２の金属板メンバーＭ１，Ｍ２の左右の凹部１４ａの没入溝１４ｃの底壁に当接させると、第１および第２の金属板メンバーＭ１，Ｍ２を脚部材１５で上下方向に所定の間隔を隔てた状態に保持できるようになる（図２の状態）。
【００３３】
この状態で、第１および第２の金属板メンバーＭ１，Ｍ２の左右の凹部１４ａの没入溝１４ｃの底壁と脚部材１５のフランジ部１５ｅ，１５ｈとをスポット溶接ｃで固定すると、横部材１２を製造することができる。
【００３４】
そして、この横部材１２を複数並列（本例では３本）して、各横部材１２の上側の第１の金属板メンバーＭ１の上面に、第３の金属板メンバーＭ３でなる縦部材１３を長さ方向に所定の間隔を隔てて複数並列（本例では５本）して、この第３の金属板メンバーＭ３の左右の凹部１４ａの没入溝１４ｃの底壁と第１の金属板メンバーＭ１の両側端（左右端）の凸部１４ｂの突出溝１４ｄの上壁とをスポット溶接ｄで固定すると、金属製パレット１１の組み立てが完了する。
【００３５】
上記金製パレット１１の脚部材１５の構造によれば、脚部材１５の両側壁部１５ａを第１および第２の金属板メンバーＭ１，Ｍ２の凹凸部１４（ａ，ｂ）と平行する方向として、嵌め込み部１５ｃ，１５ｄを第１および第２の金属板メンバーＭ１，Ｍ２の一側端と他側端の凸部１４ｂの突出溝１４ｄにそれぞれ嵌め込み、底壁部１５ｂのフランジ部１５ｅを第１および第２の金属板メンバーＭ１，Ｍ２の凹部１４ａの没入溝１４ｃの底壁に当接させてスポット溶接ｃで固定するとともに、前壁部１５ｇのフランジ部１５ｈを第１および第２の金属板メンバーＭ１，Ｍ２の凹部１４ａの没入溝１４ｃの底壁に当接させてスポット溶接ｃで固定することで、横部材１２を製造することができる。
【００３６】
したがって、脚部材１５の両側壁部１５ｂを第１および第２の金属板メンバーＭ１，Ｍ２の凹凸部１４（ａ，ｂ）と平行する方向としたことと相俟って、底壁部１５ｂと前壁部１５ｇのフランジ部１５ｅ，１５ｈを第１および第２の金属板メンバーＭ１，Ｍ２にスポット溶接ｃで固定しているから、第１の金属板メンバーＭ１と第２の金属板メンバーＭ２とに、長さ方向に互いに逆方向の力Ｆ１，Ｆ２（図２参照）が加わったときでも、脚部材１５が変形しにくくなって、横部材１２がねじれにくくなるので、横部材１２のねじれ剛性が向上するようになる。
【００３７】
また、底壁部１５ｂと前壁部１５ｇのフランジ部１５ｅ，１５ｈにより、横部材１２の圧縮（座屈）強度も向上するようになる。
【００３８】
さらに、脚部材１５のフランジ部１５ｅ，１５ｈを外向きに突出形成しているので、第１および第２の金属板メンバーＭ１，Ｍ２の凹部１４ａの没入溝１４ｃの底壁とのスポット溶接ｃによる固定が容易に行える。
【００３９】
さらにまた、図６に示したように、脚部材１５の底壁部１５ｂが第１および第２の金属板メンバーＭ１，Ｍ２の端部において、外向きとなるように配置すれば、開口１５ｆが第１および第２の金属板メンバーＭ１，Ｍ２の端部方向から見えないので、外観性が良好になる。
【００４０】
上記実施形態の脚部材１５では、前壁部１５ｇの間に開口１５ｆが開いていたが、図５（ａ）のように、脚部材１５の前壁部１５ｇの前端を、開口１５ｆを塞ぐように相互に突き合わせて、突き合わせ部分を直接に、若しくはあて板を当てがってスポット溶接ｅをしても良い。
【００４１】
あるいは、図５（ｂ）（ｃ）のように、脚部材１５の前壁部１５ｇの前端を、開口１５ｆを塞ぐように相互に重ね合わせ、重ね合わせ部分をスポット溶接ｅしても良い。
【００４２】
このようにすれば、脚部材１５が平面視で閉断面を構成して強度が向上するので、横部材１２のねじれ剛性がより向上するようになる。
