Description

【０００１】
【発明の属する技術分野】
本発明は、合成樹脂製のパレットの構造に関し、詳しくは接地する滑り止め部材をパレットに取り付ける部分の構造に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
この種の合成樹脂製のパレットは、表面部と裏面部とが、表面部と裏面部の隅部同士を連結する隅部の筒状桁と、表面部と裏面部との周囲の中間部同士を連結する中間の筒状桁と、表面部と裏面部の中央部同士を連結する中央部の筒状桁により連結され、筒状桁間にフォーク挿入孔が井桁状に形成されている。
【０００３】
このような構造のパレットで裏面部を下にして置いたとき滑り止めして接地するためにパレットの裏面の４隅に滑り止め部材が装着されるが、従来この滑り止め部材は強度的に強固なパレットの４つの隅部の筒状桁の裏面側に設けられるが、４つの隅部の筒状桁の裏面側でパレットの外周の角に偏った位置に設けられる。
【０００４】
ところが、パレットａの外の角に偏った位置に滑り止め部材ｂが装着されると、図９に示すように両端の滑り止め部材ｂ間のスパンＳが広くなり、表面部の上に荷物を載せて中央部に矢印のように荷重がかかると、パレットａが図９に示すように大きく撓むという問題がある。また上記のようにパレットａが大きく撓むためにパレットａの中央付近に荷物を載せると、その反動でパレットａの外周部が浮いてしまうという問題がある。
【０００５】
本発明は叙述の点に鑑みてなされたものであって、強度的に強固な位置に滑り止め部材を取り付けながら滑り止め部材間のスパンを小さくして荷重がかかったときのパレットの撓みを抑えることができる合成樹脂製のパレットを提供することを課題とする。
【０００６】
【課題を解決するための手段】
上記課題を解決するため本発明の合成樹脂製のパレットは、表面部１と裏面部２とが、表面部１と裏面部２の隅部同士を連結する隅部の筒状桁３と、表面部１と裏面部２との周囲の中間部同士を連結する中間の筒状桁３と、表面部１と裏面部２の中央部同士を連結する中央部の筒状桁３により連結され、且つ、筒状桁３間にフォーク挿入孔４が井桁状に形成された合成樹脂製の四方差しのパレット６において、隅部の筒状桁３内の中央の筒状桁３側に偏った位置で且つ隅部の筒状桁３の裏面側の位置に取り付け板２０を設けると共にこの取り付け板２０に接地するための滑り止部材２１を取着し、取り付け板２０の周縁の少なくとも一部と表面部１とを補強縦壁２３，２５にて一体に連結したことを特徴とする。隅部の筒状桁３の裏面側の位置の取り付け板２０に滑り止め部材２１を取り付けることにより強度的に強固な部分に滑り止め部材２１を取り付けることができ、しかも隅部の筒状桁３の中央の筒状桁３側に偏った位置に滑り止め部材２１を取り付けることにより滑り止め部材２１間のスパンＳを短くでき、荷重がかかったときのパレット６の撓みを抑えることができる。しかも取り付け板２０の周縁の少なくとも一部と表面部１とを補強縦壁２３，２５にて一体に連結したことにより、補強縦壁２３，２５にて取り付け板２０が変形しないようにさらに補強でき、滑り止め部材２１を一層強固な部分に取り付けることができる。
【０００７】
また隅部の筒状桁３内の中央の筒状桁３に偏った位置に、補強縦壁２５によって角筒状の補強柱部２２を表面部１と裏面部２とに一体に繋がるように形成し、この補強縦壁２５を有する補強柱部２２にて上記取り付け板２０を補強したことを特徴とすることも好ましい。強度的に強固な隅部の筒状桁３にさらに補強した補強柱部２２を形成し、この補強柱部２２で取り付け板２０を補強することで取り付け板２０をさらに強固に設けることができて滑り止め部材２１を強固な部分に取り付けることできる。
【０００８】
また上記取り付け板２０を桟状にして補強柱部２２内の裏面側に補強柱部２２の対角線方向に桟状の取り付け板２０を架設したことを特徴とすることも好ましい。補強柱部２２の対角線方向に架設して桟状の取り付け板２２を設けることで一層強固に補強した取り付け板２０を設けることができて滑り止め部材２１を一層強固な部分に取り付けることができる。
【０００９】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１０】
図１乃至図８には本発明のパレット６の一実施形態が示してある。パレット６は合成樹脂によって一体に射出成形してあり、表面部１と裏面部２とが、表面部１と裏面部２の隅部同士を連結する４個の隅の筒状桁３と、表面部１と裏面部２との周囲の中間部同士を連結する４個の中間の筒状桁３と、表面部１と裏面部２の中央部同士を連結する１個の中央部の筒状桁３により連結してある。このように、表面部１と裏面部２とを４個の隅の筒状桁３と、４個の中間の筒状桁３と、１個の中央部の筒状桁３とにより一体に連結することで、上記の筒状桁３間にフォーク挿入孔４が井桁状に形成された四方差しのパレット６を構成している。また、図２、図５に示すように、パレット６の裏面部２には井桁状をしたフォーク挿入孔４の交差する位置で下開口部５が形成してある。
【００１１】
図１に示すように、表面部１の中間部の筒状桁３と中央部の筒状桁３との間には桟１０が形成してあり、また、表面部１のフォーク挿入孔４が縦横に交差している部分の上方に位置する部位（つまり下開口部５の真上の部分）には桟１１が形成してある。また、表面部１の隅部の筒状桁３と中間部の筒状桁３との間には桟１２が形成してある。
【００１２】
図２に示すように、裏面部２の中間部の筒状桁３と中央部の筒状桁３との間には表面部１の桟１０と上下に重なり合わないように桟１３が形成してあり、この桟１３は図５に示すように上面側（つまりフォーク挿入孔４に面する側）の下開口部５側の両端部が傾斜部７となり、両傾斜部７の上端間が水平部１４となっている。裏面部２の隅部の筒状桁３と中間部の筒状桁３との間には桟１５が形成してあり、この桟１５は上面側（つまりフォーク挿入孔４に面する側）の下開口部５側端部及びフォーク挿入側端部がそれぞれ傾斜部７となり、両傾斜部７の上端間が水平部１４となっている。
【００１３】
したがって、裏面部２の上面にはフォーク挿入孔４の入口部分にそれぞれ傾斜部７が形成してあると共に、裏面部２に形成された４つの下開口部５の４辺に沿ってそれぞれ傾斜部７が形成してある。
【００１４】
ここで、表面部１における隅部の筒状桁３と中間部の筒状桁３を連結する部分及び中間部の筒状桁３と中央部の筒状桁３を連結する部分の上記裏面部２の傾斜部７の上方位置に対応した部位に型抜き用の細長開口部８を形成してある。
【００１５】
パレット６の４つの隅部には筒状桁３が設けられてこの隅部の筒状桁３により表面部１と裏面部２とが一体に連結されるが、この隅部の筒状桁３は外周の矩形筒状の周縦壁２４にて主体が構成されている。本発明の場合、筒状桁３は周縦壁２４以外にこの周縦壁２４で囲まれる部分を区画するように補強縦壁２５，２６を表面部１と裏面部２との間に設けて補強してある。この周縦壁２４や補強縦壁２５，２６は図７の太破線で示している。補強縦壁２５は周縦壁２内の中央の筒状桁３側の内隅部に平面から見て略Ｌ字状になるように設けてあり、周縦壁２４の隅部と補強縦壁２５とで略角筒状の補強柱部２２を形成してある。補強縦壁２６は補強縦壁２５の隅部と周縦壁２４の外の隅とを連結するように対角線方向に設けてある。
【００１６】
補強柱部２２の裏面側には取り付け板２０を一体に設けてある。本例の場合、桟状の取り付け板２０が上記補強縦壁２６と直交する補強柱部２２の対角線方向に架設してある。取り付け板２０の両側の側縁のうち一方の側縁と表面部１との間は補強縦壁２３にて一体に連結してある。この補強縦壁２３には必要に応じて軽量化のための透孔２７が穿孔されている。取り付け板２０は上記のように補強縦壁２５，２６で補強した補強柱部２２の裏面側に対角線方向に架設されると共にさらに補強縦壁２３にて支持されることにより強固に設けられる。
【００１７】
取り付け板２０の中央には円筒状の取り付け筒２８が一体に設けてあり、グロメットと称されるゴム製の滑り止め部材２１を取り付け筒２８に圧入して装着してある。取り付け板２０には軽量化するための透孔２９も設けてある。上記のように取り付け板２０の取り付け筒２８に装着した滑り止め部材２１はパレットの裏面側を下にして置いたとき、接地されて滑り止めをするのであるが、上記のようにパレット６の中央の筒状桁３側に偏った位置に滑り止め部材２１が位置するために滑り止め部材２１間のスパンＳが短くなり、パレット６の上に荷物を載せて荷重がかかったときのパレット６の撓みを抑えることができる。
【００１８】
上記のようにパレット６の裏面側に、パレット６を接地したときの滑り止め部材２１が設けられるが、パレット６の表面側にもパレット６の上に載せた荷物が滑るのを防止するための滑り止め部材が設けられる。つまり、表面部１の複数箇所に点在させて取り付け筒３０を設けてあり、この取り付け筒３０に滑り止め部材を圧入して取り付けてある。
【００１９】
なお、上記例では滑り止め部材２１を取り付けるための取り付け板２０を桟状にして補強柱部２２の対角線方向に架設し、補強縦壁２３や補強柱部２２の補強縦壁２５で桟状の取り付け板２０を補強する例について述べたが、補強柱部２２の裏面側に矩形板状の取り付け板２０を一体に設け、取り付け板２０を補強縦壁２５で補強するものでもよい。
【００２０】
【発明の効果】
本発明の請求項１の発明は、叙述の如く隅部の筒状桁内の中央の筒状桁側に偏った位置で且つ隅部の筒状桁の裏面側の位置に取り付け板を設けると共にこの取り付け板に接地するための滑り止部材を取着したので、隅部の筒状桁の裏面側の位置の取り付け板に滑り止め部材を取り付けることにより強度的に強固な部分に滑り止め部材を取り付けることができ、しかも隅部の筒状桁の中央の筒状桁側に偏った位置に滑り止め部材を取り付けることにより滑り止め部材間のスパンを短くでき、荷重がかかったときのパレットの撓みを抑えることができるものであり、さらに取り付け板の周縁の少なくとも一部と表面部とを補強縦壁にて一体に連結したので、補強縦壁にて取り付け板が変形しないようにさらに補強でき、滑り止め部材を一層強固な部分に取り付けることができるものである。
【００２１】
また本発明の請求項２の発明は、請求項１において、隅部の筒状桁内の中央の筒状桁に偏った位置に、補強縦壁によって角筒状の補強柱部を表面部と裏面部とに一体に繋がるように形成し、この補強縦壁を有する補強柱部にて上記取り付け板を補強したので、強度的に強固な隅部の筒状桁にさらに補強した補強柱部を形成し、この補強柱部で取り付け板を補強することで取り付け板をさらに強固に設けることができて滑り止め部材を強固な部分に取り付けることできるものである。
【００２２】
また本発明の請求項３の発明は、請求項２において、上記取り付け板を桟状にして補強柱部内の裏面側に補強柱部の対角線方向に桟状の取り付け板を架設したので、一層強固に補強した取り付け板を設けることができて滑り止め部材を一層強固な部分に取り付けることができるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a structure of a pallet made of synthetic resin, and more particularly to a structure of a portion for attaching a non-slip member to be grounded to the pallet.
[0002]
[Prior art and problems to be solved by the invention]
This kind of synthetic resin pallet has a cylindrical girder at the corner where the front surface and the back surface connect the corners of the front surface and the back surface, and an intermediate portion around the front surface and the back surface. Are connected by an intermediate cylindrical girder that connects the central portions of the front surface portion and the back surface portion, and a fork insertion hole is formed in a cross beam shape between the cylindrical girders.
[0003]
When a pallet having such a structure is placed with its back side facing down, anti-slip members are mounted at the four corners of the back side of the pallet to prevent slipping and contact with the ground. It is provided on the back side of the cylindrical girder at the four corners of the pallet, but is provided on the back side of the cylindrical girder at the four corners at a position biased to the corner of the outer periphery of the pallet.
[0004]
However, when the anti-slip member b is mounted at a position biased to the outer corner of the pallet a, the span S between the anti-slip members b at both ends is widened as shown in FIG. When a load is applied as shown by an arrow on the center portion, the pallet a is greatly bent as shown in FIG. Further, since the pallet a is greatly bent as described above, there is a problem that when the load is placed near the center of the pallet a, the outer periphery of the pallet a is lifted by the reaction.
[0005]
The present invention has been made in view of the above description, and while mounting the anti-slip member at a strong position, the span between the anti-slip members is reduced to suppress the bending of the pallet when a load is applied. An object is to provide a pallet made of synthetic resin.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the synthetic resin pallet of the present invention includes a front surface portion 1 and a back surface portion 2 in which the corner portions of the front surface portion 1 and the back surface portion 2 are connected to each other. Connected by an intermediate cylindrical girder 3 that connects intermediate parts around the part 1 and the back part 2, and a central cylindrical girder 3 that connects the central parts of the surface part 1 and the back part 2, and In the four-way pallet 6 made of synthetic resin in which the fork insertion holes 4 are formed in the shape of a cross between the cylindrical girders 3, at a position biased toward the central cylindrical girder 3 in the cylindrical girder 3 at the corner. In addition, a mounting plate 20 is provided at a position on the back side of the cylindrical girder 3 at the corner, and a non-slip member 21 for grounding is attached to the mounting plate 20, and at least a part of the peripheral edge of the mounting plate 20 and the surface portion 1 is integrally connected by reinforcing vertical walls 23 and 25. By attaching the anti-slip member 21 to the attachment plate 20 at the position on the back side of the cylindrical girder 3 at the corner, the anti-slip member 21 can be attached to a strong portion, and the cylindrical girder 3 at the corner. By attaching the anti-slip member 21 at a position biased toward the center cylindrical girder 3 side, the span S between the anti-slip members 21 can be shortened, and bending of the pallet 6 when a load is applied can be suppressed. Moreover, since at least a part of the peripheral edge of the mounting plate 20 and the surface portion 1 are integrally connected by the reinforcing vertical walls 23 and 25, the mounting plate 20 can be further reinforced by the reinforcing vertical walls 23 and 25 so as not to be deformed. The anti-slip member 21 can be attached to a stronger part.
[0007]
Further, the reinforcing column wall 25 is integrally connected to the front surface portion 1 and the back surface portion 2 by the reinforcing vertical wall 25 at a position deviated from the central cylindrical beam 3 in the corner cylindrical beam 3. It is also preferable that the mounting plate 20 is reinforced by the reinforcing pillar portion 22 formed and having the reinforcing vertical wall 25. By forming a reinforcing column portion 22 that is further reinforced on the cylindrical girder 3 at the corners that are strong in strength, and the reinforcing plate portion 22 reinforces the mounting plate 20, the mounting plate 20 can be provided more firmly. The anti-slip member 21 can be attached to a strong part.
[0008]
Further, it is also preferable that the mounting plate 20 is made in the shape of a rail, and the rail-like mounting plate 20 is installed in the diagonal direction of the reinforcing column 22 on the back side in the reinforcing column 22. By mounting the reinforcing plate portion 22 in the diagonal direction and providing the cross-shaped mounting plate 22, the mounting plate 20 can be provided with stronger reinforcement, and the anti-slip member 21 can be attached to a stronger portion.
[0009]

[0012]
As shown in FIG. 2, a crosspiece 13 is formed between the intermediate cylindrical girder 3 and the central cylindrical girder 3 of the back surface portion 2 so as not to overlap with the crosspiece 10 of the front surface portion 1. As shown in FIG. 5, in the crosspiece 13, both ends of the lower opening 5 side of the upper surface side (that is, the side facing the fork insertion hole 4) are inclined portions 7, and the upper ends of both inclined portions 7 are horizontal. It is part 14. A crosspiece 15 is formed between the cylindrical girder 3 at the corner of the back surface portion 2 and the middle cylindrical girder 3, and this crosspiece 15 is on the upper surface side (that is, the side facing the fork insertion hole 4). The lower opening 5 side end portion and the fork insertion side end portion are respectively inclined portions 7, and the space between the upper ends of both inclined portions 7 is a horizontal portion 14.
