【発明の属する技術分野】
本発明は、荷物が載置されるデッキボードの下面に、複数の脚部が形成されている合成樹脂製パレットに関するものである。
【０００２】
【従来の技術】
従来、デッキボードの下面の四隅に形成された、複数の上方が開放され、且つ、有底なコップ状の脚部からなる隅脚部と、隅脚部の中間に形成された、同じく複数のコップ状の脚部からなる中間脚部と、デッキボードの下面の中央部に形成された、同じく複数のコップ状の脚部からなる中央脚部とを有し、隅脚部と中間脚部との間及び中間脚部と中央脚部との間に、フォーク挿入空間が形成されている合成樹脂製パレットが知られている（例えば、実開昭５９−３８３６号公報、実開昭６０−１８９３０号公報等）。
【０００３】
上述した合成樹脂製パレットにおいては、隅脚部と中間脚部との連結領域や、中間脚部と中央脚部との連結領域や、隅脚部、中間脚部及び中央脚部との連結領域以外の領域には、交叉するリブが形成されており、この交叉リブが、荷物が載置されるデッキボードを形成することになる。
【０００４】
【発明が解決しようとする課題】
上述した従来の合成樹脂製パレットにおいては、隅脚部と中間脚部とを連結するリブや中間脚部と中央脚部とを連結するリブが、隅脚部や中間脚部や中央脚部のアールを有する角部同士を連結するものではなく、角部付近の隅脚部や中間脚部や中央脚部の変形し易い平面部を連結しているために、交叉リブが変形し易い、即ち、交叉リブにより構成されるデッキボードが変形し易いという問題があった。
【０００５】
本発明の目的は、上述した従来の合成樹脂製パレットが有する課題を解決することにある。
【０００６】
【課題を解決するための手段】
