Description

【０００１】
【発明の属する技術分野】
本発明は、荷物の運搬や保管等のために使用されるパレットに関するものである。
【０００２】
【従来の技術】
従来、それぞれ一体成形された上部デッキ部材と下部デッキ部材とを、同じく一体成形された桁部材により連結することにより、組み立てられたパレットが知られている（例えば、実公平６−１３０８１号公報や特許第２５１８７１１号公報等）。
【０００３】
【発明が解決しようとする課題】
上述した従来のパレットにおいては、上下部デッキ部材と桁部材の連結が、桁部材に形成された係止突起を、上下部デッキ部材に形成されたリブやフランジに引っ掛けるようにしただけであるので、上下部デッキ部材と桁部材の連結強度が十分ではなく、組み立てられたパレットに、落下等により衝撃が加わった際に、分解し易いという問題があった。
【０００４】
また、上述した従来のパレットにおいては、上下部デッキ部材と桁部材とが、互いに、その端部同士が当接しているだけであり、上下部デッキ部材と桁部材の一部が、互いに重複していないので、上部デッキ部材と下部デッキ部材とが、横方向にずれて、上下部デッキ部材と桁部材との連結部分が損傷したり、連結部分が外れるという問題があった。
【０００５】
本発明の目的は、上述した従来の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】
本発明は、上述した目的を達成するために、上部デッキ部材と、下部デッキ部材と、前記上部デッキ部材と下部デッキ部材とを連結する連結部材とにより組み立てられたパレットにおいて、第１には、前記上部デッキ部材と下部デッキ部材の桁嵌合部に形成された係止雌部材の一対の垂直板材間に、前記連結部材を構成する係止雄壁部材の上部雄部及び下部雄部が嵌入されるとともに、前記垂直板材に形成された係止爪が、前記係止雄壁部材に形成されたスリットを構成する端面に係止されるように構成されているものであり、第２には、連結部材の仕切り壁を、桁嵌合部に配設された保持部材の一対の垂直板材間に形成された間隙に挿入するようにしたものであり、第３には、連結部材の筒部を、桁嵌合部の外周壁と周辺板部材との間に形成された間隙に挿入するようにしたものであり、第４には、仕切り壁により分割された連結部材の２つの空間領域のうち、一方の空間領域に形成された複数の係止雄壁部材の上部雄部と下部雄部の配置と、もう一方の空間領域に形成された複数の係止雄壁部材の上部雄部と下部雄部の配置とが、平面的に見て、連結部材の中心点に対して、点対称になるように構成したものであり、第５には、平面形状が長方形の四方差しパレットの、長辺側に位置する中間部連結部材の色や色相と、短辺側に位置する中間部連結部材の色や色相とを異なるように構成したものである。
【０００７】
【実施例】
以下に、本発明の実施例について説明するが、本発明の趣旨を越えない限り何ら、本実施例に限定されるものではない。
【０００８】
図１に示されているように、本発明のパレットは、上部デッキ部材Ｐａと下部デッキ部材Ｐｂと複数の連結部材Ｃとから構成されており、上部デッキ部材Ｐａと下部デッキ部材Ｐｂとを、連結部材Ｃにより連結することによりパレットが組み立てられるように構成されている。
【０００９】
先ず最初に、主として、図１〜図７を用いて、上部デッキ部材Ｐａ及び下部デッキ部材Ｐｂについて説明する。
【００１０】
図１や図２等に示されているように、上部デッキ部材Ｐａは、平面形状が、略方形状の上部デッキボード１を有しており、上部デッキボード１は、後述する桁嵌合部が配設されている以外の部分は、縦横に走る交差リブ１ａ、１ｂにより構成されている。勿論、上部デッキボード１を、板材と、板材の裏面に垂設された交差リブとから構成することもできる。
【００１１】
下部デッキ部材Ｐｂは、上述した上部デッキ部材Ｐａと同一の構成とすることもできる。この場合には、上部デッキ部材Ｐａと下部デッキ部材Ｐｂと桁部材Ｃとにより組み立てられたパレットは、両面使用のパレットとなる。本実施例においては、図４や図５等に示されているように、下部デッキ部材Ｐｂは、額縁状に配置された４つのの周辺桟部２と、相対する周辺桟部２の中央部を連結する連結桟部３とを有しており、周辺桟部２と連結桟部３とにより囲まれた領域４は、開口として形成されている。
【００１２】
上部デッキ部材Ｐａと下部デッキ部材Ｐｂの４つの隅部には、それぞれ、角筒状の隅桁嵌合部５が形成されており、上部デッキ部材Ｐａと下部デッキ部材Ｐｂの隅桁嵌合部５の間には、それぞれ、角筒状の中間桁嵌合部６が形成されており、更に、上部デッキ部材Ｐａと下部デッキ部材Ｐｂの中央部には、それぞれ、角筒状の中央桁嵌合部７が形成されている。
【００１３】
次に、図６及び図７等を用いて、隅桁嵌合部５、中間桁嵌合部６及び中央桁嵌合部７について説明するが、隅桁嵌合部５、中間桁嵌合部６及び中央桁嵌合部７の基本的な構成は同じであるので、以下については、隅桁嵌合部５を用いて、その構成について説明し、その後、隅桁嵌合部５と異なる中間桁嵌合部６及び中央桁嵌合部７の相違点について説明する。
【００１４】
隅桁嵌合部５は、角筒状の外周壁５ａを有しており、外周壁５ａの一方の相対する側壁５ａ１の略中間領域には、一方の相対する側壁５ａ１に平行に、所定の間隔を置いて複数の保持部材Ｈ１が配設されている。保持部材Ｈ１は、所定の間隙を置いて配置された一対の垂直板材ｈ１から構成されており、一方の相対する側壁５ａ１に平行に配設された複数の保持部材Ｈ１は、一対の垂直板材ｈ１間に形成されている間隙が、一直線状に並ぶように配置されている。本実施例には、一例として、３個の保持部材Ｈ１が配設されている例が示されている。なお、ｈ２は、一対の垂直板材ｈ１の相対する側面に対して反対側の側面に形成された三角形状の補強リブである。
【００１５】
また、外周壁５ａの内側壁に沿って、且つ、外周壁５ａから所定の間隙を置いて、板状の周辺板部材Ｈ２が、適当数、配設されている。ｈ３は、周辺板部材Ｈ２の外周壁５ａの内側壁に対して反対側の側面に、適宜、形成された、上述した補強リブｈ２と同様の三角形状の補強リブである。
【００１６】
Ｇは、図８に示されているように、所定の間隔を置いて配置された一対の垂直板材ｇ１と、垂直板材ｇ１の先端部から、互いに対向するとともに互いに接近する方向に延在する係止爪ｇ２とからなる係止雌部材であり、一対の係止爪ｇ２の先端間には、所定の間隙が形成されている。また、一対の垂直板材ｇ１の先端部の対向する側面は、下方から上方に行くに従って、外側に傾斜した傾斜面ｇ３として形成されており、係止雌部材Ｇの上部には、楔状空間部ｇ４が形成されている。
【００１７】
本実施例には、外周壁５ａと、直線状に３個配設された保持部材Ｈ１とにより仕切られた隅桁嵌合部５の２つの領域Ａ１、Ａ２に、それぞれ、３個ずつの係止雌部材Ｇが、隣り合う係止雌部材Ｇを構成する垂直板材ｇ１が、互いに平行になるように配設されており、且つ、垂直板材ｇ１は、外周壁５ａのもう一方の相対する側壁５ａ２と略平行になるように配置されている。また、図６等に示されているように、上記領域Ａ１、Ａ２に、それぞれ配設された３個の係止雌部材Ｇは、等間隔に配設されておらず、中間に位置する係止雌部材（以下、中間係止雌部材と称し、符号Ｇｃを付す。）は、両端部に位置する係止雌部材Ｇのうち、一方の係止雌部材Ｇに、より近づいて配置されている。以下、便宜的に、端部に位置する係止雌部材Ｇのうち、中間係止雌部材Ｇｃに、より近づいて配置された係止雌部材Ｇを、中間係止雌部材側の端部係止雌部材と称し、符号Ｇｅ１を付し、中間係止雌部材Ｇｃに、より遠い位置にある係止雌部材Ｇを、単に、端部係止雌部材と称し、符号Ｇｅ２を付す。
【００１８】
隅桁嵌合部５の一方の領域Ａ１に配設された、中間係止雌部材Ｇｃ、中間係止雌部材側の端部係止雌部材Ｇｅ１及び端部係止雌部材Ｇｅ２の配置は、隅桁嵌合部５のもう一方の領域Ａ２に配設された、中間係止雌部材Ｇｃ、中間係止雌部材側の端部係止雌部材Ｇｅ１及び端部係止雌部材Ｇｅ２の配置とは、平面的に見て、隅桁嵌合部５の中心点に対して、点対称になるように構成されている。また、隅桁嵌合部５には、外周壁５ａと所定の周辺板部材Ｈ２との間に延在するとともに、外周壁５ａの上端まで延在する位置決め挿入片Ｔ１が形成されている。
【００１９】
上述した保持部材Ｈ１、周辺板部材Ｈ２及び係止部材Ｇ（中間係止雌部材Ｇｃ、中間係止雌部材側の端部係止雌部材Ｇｅ１、端部係止雌部材Ｇｅ２）は、略同じ高さに形成されており、また、隅桁嵌合部５の外周壁５ａの高さより、低く形成されている。なお、本実施例においては、係止部材Ｇが、保持部材Ｈ１及び周辺板部材Ｈ２より、若干、高くなるように構成されている。
【００２０】
上述した中央桁嵌合部７は、隅桁嵌合部５と実質的に同じ構成を有しており、また、隅桁嵌合部５と同様に、中央桁嵌合部７の外周壁７ａと、所定の周辺板部材Ｈ２との間に延在するとともに、外周壁７ａの上端まで延在する位置決め挿入片Ｔ２が形成されている。中間桁嵌合部６は、このような位置決め挿入片Ｔ１、Ｔ２が形成されていない点で、隅桁嵌合部５と中央桁嵌合部７とは相違するが、それ以外の構成は、実質的に同じである。
【００２１】
次に、上述した上部デッキ部材Ｐａと下部デッキ部材Ｐｂの隅桁嵌合部５同士を連結する隅部連結部材Ｃ１、上部デッキ部材Ｐａと下部デッキ部材Ｐｂの中間桁嵌合部６同士を連結する中間部連結部材Ｃ２及び上部デッキ部材Ｐａと下部デッキ部材Ｐｂの中央桁嵌合部７同士を連結する中央部連結部材Ｃ３について説明するが、上記の隅部連結部材Ｃ１、中間部連結部材Ｃ２及び中央部連結部材Ｃ３の基本的な構成は同じであるので、以下においては、図９〜図１２を用いて、隅部連結部材Ｃ１を例に、その構成について説明し、隅部連結部材Ｃ１と異なる中間部連結部材Ｃ２及び中央部連結部材Ｃ３の相違点については別途、説明することにする。
【００２２】
隅部連結部材Ｃ１は、上述した隅桁嵌合部５の外周壁５ａ内に嵌合可能なように、隅桁嵌合部５の外周壁５ａより若干小さめで相似形状の筒部ｃ１と、筒部ｃ１を構成する一方の相対する側壁ｃ１ａと略平行で、且つ、その中間に配設された仕切り壁ｃ２とを有しており、仕切り壁ｃ２は、もう一方の相対する側壁ｃ１ｂを架橋するとともに、筒部ｃ１の下端から上端まで延在している。この仕切り壁ｃ２により、隅部連結部材Ｃ１は、２つの空間領域Ａ１’、Ａ２’に分けられている。この仕切り壁ｃ２は、上部デッキ部材Ｐａの隅桁嵌合部５と下部デッキ部材Ｐｂの隅桁嵌合部５とを、隅部連結部材Ｃ１により連結した際には、隅桁嵌合部５に配設された保持部材Ｈ１を構成する一対の垂直板材ｈ１間に形成された間隙に挿入されるように構成されている。
【００２３】
隅部連結部材Ｃ１の筒部ｃ１の一方の相対する側壁ｃ１ａと仕切り壁ｃ２とは、筒部ｃ１の上下端まで延在する係止雄壁部材ｃ３により連結されている。本実施例においては、仕切り壁ｃ２を挟んで位置する空間領域Ａ１’、Ａ２’には、上述した隅桁嵌合部５の２つの領域Ａ１、Ａ２に、それぞれ形成された中間係止雌部材Ｇｃ、中間係止雌部材側の端部係止雌部材Ｇｅ１及び端部係止雌部材Ｇｅ２に対応して．それぞれ３個の係止雄壁部材ｃ３が形成されている。
【００２４】
隅部連結部材Ｃ１の係止雄壁部材ｃ３は、筒部ｃ１の相対する側壁ｃ１ｂに略平行な中部壁部ｃ３ａと、中部壁部ｃ３ａの上部に形成された上部雄部ｃ３ｂと、中部壁部ｃ３ａの下部に形成された下部雄部ｃ３ｃとを有しており、中部壁部ｃ３ａと上部雄部ｃ３ｂとは、上部傾斜部ｃ３ｄにより連結されており、また、中部壁部ｃ３ａと下部雄部ｃ３ｃとは、下部傾斜部ｃ３ｅにより連結されている。そして、上部傾斜部ｃ３ｄと下部傾斜部ｃ３ｅには、上述した係止部材Ｇ（中間係止雌部材Ｇｃ、中間係止雌部材側の端部係止雌部材Ｇｅ１、端部係止雌部材Ｇｅ２）の垂直板材ｇ１の幅より、若干．広く、且つ、垂直板材ｇ１が挿入可能な奥行きを有するスリットｃ３ｄ’、ｃ３ｅ’が、それぞれ穿設されている。
【００２５】
仕切り壁ｃ２を挟んで位置する空間領域Ａ１’、Ａ２’に、それぞれ配設された３個ずつの係止雄壁部材ｃ３を構成する上部雄部ｃ３ｂ同士及び下部雄部ｃ３ｃ同士の間隔は、等間隔に配設されていない。即ち、中間に位置する上部雄部ｃ３ｂ（以下、中間上部雄部と称し、符号ｃ３ｂ１を付す。）は、両端部に位置する上部雄部ｃ３ｂのうち、一方の上部雄部ｃ３ｂに、より近づいて配置されている。以下、便宜的に、端部に位置する上部雄部ｃ３ｂのうち、中間上部雄部ｃ３ｂ１に、より近づいて配置された上部雄部ｃ３ｂを、中間上部雄部側の端部上部雄部と称し、符号ｃ３ｂ２を付し、中間上部雄部ｃ３ｂ１に対して、より遠い位置にある上部雄部ｃ３ｂを、単に、端部上部雄部と称し、符号ｃ３ｂ３を付す。同様に、中間に位置する下部雄部ｃ３ｃ（以下、中間下部雄部と称し、符号ｃ３ｃ１を付す。）は、両端部に位置する下部雄部ｃ３ｃのうち、一方の下部雄部ｃ３ｃに、より近づいて配置されている。以下、便宜的に、端部に位置する下部雄部ｃ３ｃのうち、中間下部雄部ｃ３ｃ１に、より近づいて配置された下部雄部ｃ３ｃを、中間下部雄部側の端部下部雄部と称し、符号ｃ３ｃ２を付し、中間下部雄部ｃ３ｃ１に対して、より遠い位置にある下部雄部ｃ３ｃを、単に、端部ｃ部雄部と称し、符号ｃ３ｃ３を付す。
【００２６】
隅部連結部材Ｃ１の一方の空間領域Ａ１’に配設された、中間上部雄部ｃ３ｂ１、中間上部雄部側の端部上部雄部ｃ３ｂ２及び端部上部雄部ｃ３ｂ３の配置は、隅部連結部材Ｃ１のもう一方の空間領域Ａ２’に配設された、中間上部雄部ｃ３ｂ１、中間上部雄部側の端部上部雄部ｃ３ｂ２及び端部上部雄部ｃ３ｂ３の配置とは、平面的に見て、隅部連結部材Ｃ１の中心点に対して、点対称になるように構成されている。同様に、隅部連結部材Ｃ１の一方の空間領域Ａ１’に配設された、中間下部雄部ｃ３ｃ１、中間下部雄部側の端部下部雄部ｃ３ｃ２及び端部下部雄部ｃ３ｃ３の配置は、隅部連結部材Ｃ１のもう一方の空間領域Ａ２’に配設された、中間下部雄部ｃ３ｃ１、中間下部雄部側の端部下部雄部ｃ３ｃ２及び端部下部雄部ｃ３ｃ３の配置とは、平面的に見て、隅部連結部材Ｃ１の中心点に対して、点対称になるように構成されている。
【００２７】
また、隅部連結部材Ｃ１の筒部ｃ１の相対する側壁ｃ１ｂの一方の上部には、上述した上部デッキ部材Ｐａの隅桁嵌合部５に形成された位置決め挿入片Ｔ１が挿入可能な上部スリットＳ１が形成されており、また、隅部連結部材Ｃ１の筒部ｃ１の相対する側壁ｃ１ｂのもう一方の下部には、上述した下部デッキ部材Ｐｂの隅桁嵌合部５に形成された位置決め挿入片Ｔ１が挿入可能な下部スリットＳ２が形成されている。
【００２８】
上述した中間部連結部材Ｃ２は、上述した上部スリットＳ１及び下部スリットＳ２が形成されていない以外は、隅部連結部材Ｃ１と実質的に同じ構成を有している。また、中央部連結部材Ｃ３には、図１３に示されているように、中央部連結部材Ｃ３の筒部ｃ１の所定の１つの側壁ｃ１ｂに、上部スリットＳ１と下部スリットＳ２が形成されており、上部スリットＳ１は、一方の領域Ａ２’側に位置する側壁ｃ１ｂの上部に形成されており、また、下部スリットＳ２は、もう一方の領域Ａ１’側に位置する側壁ｃ１ｂの下部に形成されている。上部スリットＳ１と下部スリットＳ２の配置以外の中央部連結部材Ｃ３の構成は、隅部連結部材Ｃ１と実質的に同じ構成を有している。
【００２９】
上述したように、仕切り壁ｃ２により分割された隅部連結部材Ｃ１の２つの空間領域Ａ１’、Ａ２’のうち、一方の空間領域Ａ１’に形成された３つの係止雄壁部材ｃ３の上部雄部ｃ３ｂと下部雄部ｃ３ｃの配置と、もう一方の空間領域Ａ２’に形成された３つの係止雄壁部材ｃ３の上部雄部ｃ３ｂと下部雄部ｃ３ｃの配置とが、平面的に見て、隅部連結部材Ｃ１の中心点に対して、点対称になるように構成されているので、上述した構成する上部デッキ部材Ｐａの隅桁嵌合部５同士を、隅部連結部材Ｃ１により連結することができるとともに、中間部連結部材Ｃ２及び中央部連結部材Ｃ３も、隅部連結部材Ｃ１と同様に構成されているので、上部デッキ部材Ｐａの中間桁嵌合部６同士を、中間部連結部材Ｃ２により連結することができ、また、上部デッキ部材Ｐａの中央桁嵌合部７同士を、中央桁嵌合部７により連結することができる。従って、２つの上部デッキ部材Ｐａと、４つの隅部連結部材Ｃ１と、４つの中間部連結部材Ｃ２と、１つの中央部連結部材Ｃ３により、両面使用のパレットを組み立てることができる。
【００３０】
次に、主として、図３及び図５を用いて、上部デッキ部材Ｐａ及び下部デッキ部材Ｐｂへの隅桁嵌合部５、中間桁嵌合部６及び中央桁嵌合部７の配置向きの一例について説明する。
【００３１】
隅桁嵌合部５と中央桁嵌合部７を構成する保持部材Ｈ１の垂直板材ｈ１は、上部デッキ部材Ｐａ及び下部デッキ部材Ｐｂの一方の相対する辺ｐ１に対して、略平行になるように配置されており、従って、保持部材Ｈ１を構成する一対の垂直板材ｈ１間に形成された間隙は、上記の一方の相対する辺ｐ１に沿って配置されることになる。また、隅桁嵌合部５と中央桁嵌合部７を構成する係止雌部材Ｇを構成する垂直板材ｇ１は、上部デッキ部材Ｐａ及び下部デッキ部材Ｐｂのもう一方の相対する辺ｐ２に対して、略平行になるように配置されている。
【００３２】
中間桁嵌合部６は、全て、中間桁嵌合部６を構成する保持部材Ｈ１の垂直板材ｈ１が、上部デッキ部材Ｐａ及び下部デッキ部材Ｐｂの辺ｐ１、ｐ２に対して、略直角になるように配置されており、従って、保持部材Ｈ１を構成する一対の垂直板材ｈ１間に形成された間隙は、上部デッキ部材Ｐａ及び下部デッキ部材Ｐｂの辺ｐ１、ｐ２に対して略直角になるように配置されることになる。また、中間桁嵌合部６を構成する係止雌部材Ｇを構成する垂直板材ｇ１は、上部デッキ部材Ｐａ及び下部デッキ部材Ｐｂの辺ｐ１、ｐ２に対して、略平行になるように配置されている。
【００３３】
次に、図１２及び図１４〜図１７を用いて、上部デッキ部材Ｐａと下部デッキ部材Ｐｂとを、隅部連結部材Ｃ１、中間部連結部材Ｃ２及び中央部連結部材Ｃ３を用いて組み立てる工程及び組み立てられた状態について説明する。
【００３４】
図１２等に示されているように、上下部デッキ部材Ｐａ、Ｐｂの各桁嵌合部５、６、７に配設された係止雌部材Ｇの一対の垂直板材ｇ１間に形成された楔状空間部ｇ４と、連結部材Ｃを構成する係止雄壁部材ｃ３の上部雄部ｃ３ｂ或いは下部雄部ｃ３ｃとを、対向するように配置し、その後、係止雌部材Ｇと連結部材Ｃとを接近させて、係止雌部材Ｇの一対の垂直板材ｇ１間に形成された楔状空間部ｇ４に、傾斜面ｇ３に沿って、連結部材Ｃを構成する係止雄壁部材ｃ３の上部雄部ｃ３ｂ或いは下部雄部ｃ３ｃを嵌入するとともに、図１５に示されているように、連結部材Ｃの上部傾斜部ｃ３ｄ或いは下部傾斜部ｃ３ｅに形成されたスリットｃ３ｄ’、ｃ３ｅ’に、係止雌部材Ｇの係止爪ｇ２の一部を挿入し、係止爪ｇ２を、上部雄部ｃ３ｂ或いは下部雄部ｃ３ｃのスリットｃ３ｄ’、ｃ３ｅ’との対向端面ｃ３ｃ’、ｃ３ｃ”に係止させることにより、各桁嵌合部５、６、７を構成する係止雌部材Ｇと、各連結部材Ｃ１、Ｃ２、Ｃ３を構成する係止雄壁部材ｃ３とを連結する。上記のように、係止雌部材Ｇの一対の垂直板材ｇ１間に形成された間隙に、この間隙より肉厚の、連結部材Ｃを構成する係止雄壁部材ｃ３の上部雄部ｃ３ｂ或いは下部雄部ｃ３ｃを嵌入することになるが、この嵌入作業の際には、係止雌部材Ｇの一対の垂直板材ｇ１が、その弾性力により、外側に拡張し、上記のように、係止雌部材Ｇの係止爪ｇ２が、上部雄部ｃ３ｂ或いは下部雄部ｃ３ｃのスリットｃ３ｄ’、ｃ３ｅ’との対向端面ｃ３ｃ’、ｃ３ｃ”に係止した時点で、垂直板材ｇ１が、略垂直な元の状態に戻るように構成されている。
【００３５】
上述したように、上部デッキ部材Ｐａと下部デッキ部材Ｐｂに形成された隅桁嵌合部５、中間桁嵌合部６及び中央桁嵌合部７を構成する係止雌部材Ｇと、隅部連結部材Ｃ１、中間部連結部材Ｃ２及び中央部連結部材Ｃ３とを連結した際には、隅部連結部材Ｃ１、中間部連結部材Ｃ２及び中央部連結部材Ｃ３の仕切り壁ｃ２は、隅桁嵌合部５、中間桁嵌合部６及び中央桁嵌合部７に配設された保持部材Ｈ１の一対の垂直板材ｈ１間に形成された間隙に挿入されるとともに、隅部連結部材Ｃ１、中間部連結部材Ｃ２及び中央部連結部材Ｃ３の筒部ｃ１は、隅桁嵌合部５の外周壁５ａと周辺板部材Ｈ２との間に形成された間隙、中間桁嵌合部６の外周壁６ａと周辺板部材Ｈ２との間に形成された間隙及び中央桁嵌合部７の外周壁７ａと周辺板部材Ｈ２との間に形成された間隙に、それぞれ挿入されるように構成されている。
【００３６】
上述したようにして、隅部連結部材Ｃ１、中間部連結部材Ｃ２及び中央部連結部材Ｃ３を介して、上部デッキ部材Ｐａと下部デッキ部材Ｐｂとが連結されて、パレットが組み立てられることになる。
【００３７】
パレットが組み立てられた状態においては、上下部デッキ部材Ｐａ、Ｐｂの各桁嵌合部５、６、７に配設された係止雌部材Ｇの一対の垂直板材ｇ１間に、連結部材Ｃの係止雄壁部材ｃ３を構成する上部雄部ｃ３ｂ或いは下部雄部ｃ３ｃが嵌入されているとともに、垂直板材ｇ１に形成された係止爪ｇ２が、連結部材Ｃの上部雄部ｃ３ｂ或いは下部雄部ｃ３ｃのスリットｃ３ｄ’、ｃ３ｅ’との対向端面ｃ３ｃ’、ｃ３ｃ”に係止されているので、上下部デッキ部材Ｐａ、Ｐｂに対して、連結部材Ｃが、ガタついたり、水平移動するようなことがなく、従って、垂直板材ｇ１に形成された係止爪ｇ２と、連結部材Ｃの上部雄部ｃ３ｂ或いは下部雄部ｃ３ｃのスリットｃ３ｄ’、ｃ３ｅ’との対向端面ｃ３ｃ’、ｃ３ｃ”との係止状態が解除されるようなことが、確実に防止できる。
【００３８】
また、パレットが組み立てられた状態においては、隅部連結部材Ｃ１、中間部連結部材Ｃ２及び中央部連結部材Ｃ３の仕切り壁ｃ２が、隅桁嵌合部５、中間桁嵌合部６及び中央桁嵌合部７に配設された保持部材Ｈ１の一対の垂直板材ｈ１間に形成された間隙に挿入されているので、上下部デッキ部材Ｐａ、Ｐｂに対して、連結部材Ｃが、ガタついたり、水平移動するようなことを、より確実に防止することができ、ひいては、垂直板材ｇ１に形成された係止爪ｇ２と、連結部材Ｃの上部雄部ｃ３ｂ或いは下部雄部ｃ３ｃのスリットｃ３ｄ’、ｃ３ｅ’との対向端面ｃ３ｃ’、ｃ３ｃ”との係止状態が解除されるようなことが、より確実に防止できる。
【００３９】
更に、隅部連結部材Ｃ１、中間部連結部材Ｃ２及び中央部連結部材Ｃ３の筒部ｃ１が、隅桁嵌合部５の外周壁５ａと周辺板部材Ｈ２との間に形成された間隙、中間桁嵌合部６の外周壁６ａと周辺板部材Ｈ２との間に形成された間隙及び中央桁嵌合部７の外周壁７ａと周辺板部材Ｈ２との間に形成された間隙に、それぞれ挿入されるように構成されているので、上下部デッキ部材Ｐａ、Ｐｂに対して、連結部材Ｃが、ガタついたり、水平移動するようなことを、更に確実に防止することができ、ひいては、垂直板材ｇ１に形成された係止爪ｇ２と、連結部材Ｃの上部雄部ｃ３ｂ或いは下部雄部ｃ３ｃのスリットｃ３ｄ’、ｃ３ｅ’との対向端面ｃ３ｃ’、ｃ３ｃ”との係止状態が解除されるようなことが、更に確実に防止できる。
【００４０】
更にまた、上下部デッキ部材Ｐａ、Ｐｂに配設された隅桁嵌合部５及び中央桁嵌合部７に位置決め挿入片Ｔ１、Ｔ２を形成するとともに、パレットの組立作業の際に、位置決め挿入片Ｔ１、Ｔ２が、隅部連結部材Ｃ１及び中央部連結部材Ｃ３の筒部ｃ１に形成された上部スリットＳ１及び下部スリットＳ２に挿入するように構成されているので、上下部デッキ部材Ｐａ、Ｐｂに配設された隅桁嵌合部５に嵌合される隅部連結部材Ｃ１の嵌合位置を間違うようなことがなく、また、上下部デッキ部材Ｐａ、Ｐｂに配設された隅桁嵌合部５に、誤って、中間部連結部材Ｃ２や中央部連結部材Ｃ３が嵌合されるようなことがない。また、同様に、上下部デッキ部材Ｐａ、Ｐｂに配設された中央桁嵌合部７に嵌合される中央部連結部材Ｃ３の嵌合位置を間違うようなことがなく、また、上下部デッキ部材Ｐａ、Ｐｂに配設された中央桁嵌合部７に、誤って、隅部連結部材Ｃ１や中間部連結部材Ｃ２が嵌合されるようなことがない。更には、上下部デッキ部材Ｐａ、Ｐｂに配設された中間桁嵌合部６に、誤って、隅部連結部材Ｃ１や中央部連結部材Ｃ３が嵌合されるようなことがない。
【００４１】

Are connected to the opposite end faces c3c ′, c3c ″ of the slits c3d ′, c3e ′, so that the connecting member C rattles or moves horizontally with respect to the upper and lower deck members Pa, Pb. Therefore, the engagement between the locking claw g2 formed on the vertical plate member g1 and the end faces c3c ′ and c3c ″ facing the slits c3d ′ and c3e ′ of the upper male part c3b or the lower male part c3c of the connecting member C Such that the stop state is released Theft is, can be reliably prevented.
[0038]
When the pallet is assembled, the partition walls c2 of the corner connecting member C1, the intermediate connecting member C2, and the central connecting member C3 are connected to the corner girder fitting part 5, the intermediate girder fitting part 6, and the central girder. Since it is inserted into the gap formed between the pair of vertical plate members h1 of the holding member H1 disposed in the fitting portion 7, the connecting member C is loose with respect to the upper and lower deck members Pa and Pb. Therefore, it is possible to prevent the horizontal movement more reliably. As a result, the locking claw g2 formed on the vertical plate material g1 and the slit c3d ′ of the upper male part c3b or the lower male part c3c of the connecting member C are obtained. , C3e ′ can be more reliably prevented from being released from the locked state with the opposed end faces c3c ′ and c3c ″.
[0039]
Further, the cylindrical portion c1 of the corner portion connecting member C1, the intermediate portion connecting member C2, and the central portion connecting member C3 has a gap formed between the outer peripheral wall 5a of the corner beam fitting portion 5 and the peripheral plate member H2. Inserted into the gap formed between the outer peripheral wall 6a of the girder fitting portion 6 and the peripheral plate member H2 and the gap formed between the outer peripheral wall 7a of the central girder fitting portion 7 and the peripheral plate member H2, respectively. Therefore, it is possible to more reliably prevent the connecting member C from rattling or horizontally moving with respect to the upper and lower deck members Pa and Pb. The locking state between the locking claw g2 formed on the plate material g1 and the end faces c3c ′ and c3c ″ facing the slits c3d ′ and c3e ′ of the upper male part c3b or the lower male part c3c of the connecting member C is released. This can be prevented more reliably.
[0040]
Furthermore, positioning insertion pieces T1 and T2 are formed in the corner girder fitting portion 5 and the central girder fitting portion 7 disposed on the upper and lower deck members Pa and Pb, and positioning insertion is performed during the pallet assembling operation. Since the pieces T1, T2 are configured to be inserted into the upper slit S1 and the lower slit S2 formed in the cylindrical portion c1 of the corner connecting member C1 and the central connecting member C3, the upper and lower deck members Pa, Pb The corner connecting member C1 fitted to the corner girder fitting portion 5 arranged in the corner does not have the wrong fitting position, and the corner girder fitted in the upper and lower deck members Pa and Pb The intermediate portion connecting member C2 and the central portion connecting member C3 are not erroneously fitted into the joint portion 5. Similarly, the fitting position of the central connecting member C3 fitted to the central girder fitting part 7 disposed on the upper and lower deck members Pa and Pb is not mistaken, and the upper and lower decks are not misplaced. There is no possibility that the corner connecting member C1 and the intermediate connecting member C2 are mistakenly fitted into the center beam fitting portion 7 disposed on the members Pa and Pb. Furthermore, the corner connecting member C1 and the center connecting member C3 are not erroneously fitted to the intermediate beam fitting portions 6 arranged on the upper and lower deck members Pa and Pb.
[0041]
As shown in FIG. 17, the upper deck member Pa and the lower deck member Pb are connected via the corner connecting member C1, the intermediate connecting member C2, and the central connecting member C3, as described above. A fork insertion space F is formed between the corner connecting member C1 and the intermediate connecting member C2 and between the intermediate connecting member C2 and the central connecting member C3. Two fork insertion spaces F are formed on each side of the pallet, and a so-called four-way pallet is assembled.
[0042]
When the planar shape of the four-way pallet is rectangular, in order to easily identify the long side and the short side of the pallet, the color and hue of the intermediate connecting member C2 positioned on the long side and the short side The intermediate portion connecting member C2 located on the side is configured to change the color and hue. By configuring in this way, the long side and the short side of the four-way pallet can be easily identified, so that the operator can reliably and quickly achieve the desired side surface of the four-way pallet. Can be located. Especially when there is little difference in the length in the width direction between the long side and the short side of the four-way pallet, and the long side and the short side cannot be distinguished depending on the difference in length. In this way, by configuring the color and hue of the intermediate part connecting member C2 located on the long side to be different from the color and hue of the intermediate part connecting member C2 located on the short side, The long side and the short side of the four-way pallet can be easily and quickly identified.
[0043]
Further, the color and hue of the intermediate connection member C2 of the four-way pallet are configured so as to be different from the colors and hues of the corner connection member C1 and the central connection member C3, thereby positioning the intermediate connection member C2 therebetween. The position of the fork insertion space portion F to be viewed can be easily and quickly visually recognized, and therefore the workability of the fork insertion work into the fork insertion space portion F is improved.
[0044]
【The invention's effect】
Since this invention has the structure demonstrated above, there exists an effect described below.
[0045]
The upper male portion and the lower male portion of the locking male wall member constituting the connecting member are inserted between a pair of vertical plate members of the locking female member formed in the girder fitting portion of the upper deck member and the lower deck member. In addition, since the locking claw formed on the vertical plate member is configured to be locked to the end surface forming the slit formed in the locking male wall member, it is connected to the upper and lower deck members. The member does not rattle or move horizontally, and therefore it is possible to reliably prevent the locked state between the girder fitting portion of the upper and lower deck members and the connecting member from being released.
[0046]
Since the partition wall of the connecting member is inserted into the gap formed between the pair of vertical plate members of the holding member disposed in the girder fitting portion, the connecting member is loose with respect to the upper and lower deck members. And the horizontal movement can be more reliably prevented, and therefore, the locking state between the girder fitting portion of the upper and lower deck members and the connecting member is more reliably prevented. it can.
[0047]
Since the cylindrical portion of the connecting member is inserted into the gap formed between the outer peripheral wall of the girder fitting portion and the peripheral plate member, the connecting member is loose or horizontal with respect to the upper and lower deck members. Therefore, it is possible to more reliably prevent the locking state between the girder fitting portion of the upper and lower deck members and the connecting member from being released.
[0048]
Of the two space regions of the connecting member divided by the partition wall, the arrangement of the upper and lower male portions of the plurality of locking male wall members formed in one space region and the other space region are formed. Since the arrangement of the upper male portion and the lower male portion of the plurality of locking male wall members is configured to be point symmetric with respect to the center point of the connecting member when seen in a plan view, A double-sided pallet can be assembled with the deck member and the connecting member.
[0049]
Easy because the color and hue of the intermediate connection member located on the long side and the color and hue of the intermediate connection member located on the short side of the rectangular four-way pallet with a planar shape are different. In addition, the long side and the short side of the four-way pallet can be distinguished quickly, and the position of the fork insertion space located between the intermediate connecting members can be easily and quickly determined. Therefore, the workability of the fork insertion work into the fork insertion space is improved.
