Description

【技術分野】
【０００１】
本発明は、種々の荷物を運搬および保管する際に使用される合成樹脂製パレットであり、フォークリフトやパレットトラック等で運搬することができる合成樹脂製パレットに関する。
【背景技術】
【０００２】
一般に、荷物を運搬および保管する際に使用されるパレットとして、合成樹脂を射出することにより成形された合成樹脂製パレットが提供されている。例えば特開２００１−７２０６３号公報および特開２０００−１６４３０号公報は、開示するフォークリフト等のフォーク部を２方向から差し込める二方差しの合成樹脂製パレットや４方向から差し込める四方差しの合成樹脂製パレットを開示している。
【０００３】
この種の合成樹脂製パレットは、互いに平行に配置された上面板状部および下面板状部と、これら上面板状部および下面板状部を連結する桁部とから構成される。上面板状部と下面板状部とは、両端側および中間にそれぞれ配列されている桁部によって連結されており、上面板状部と下面板状部との間には一対のフォーク挿入孔が形成されている。つまり、上面板状部と下面板状部との外周部分を囲む側面部には、桁部とフォーク挿入孔の開口部とが設けられている。
【０００４】
合成樹脂製パレットは、荷物をまとめて運搬および保管するのに使用される。具体的には、その上面に荷物を載せた状態で一対のフォーク挿入孔にフォークリフトやパレットトラックのフォーク部を挿入して合成樹脂製パレットごとトラックの荷台や倉庫に載置する。
【０００５】
しかしながら、荷台の後方部分のみが開口するトラックに複数の合成樹脂製パレットを縦列するように載置する場合であって、荷台の奥行きがフォーク部の長さに対して充分長いときには、荷台の後方側から積み込むため合成樹脂製パレットを荷台の前方側へ載置できない。
このようにフォークリフト等のフォーク部をフォーク挿入孔に挿入したままで合成樹脂製パレットを所望の場所に載置できない場合には、フォークリフト等のフォーク部先端で合成樹脂製パレットの側面部を押圧して合成樹脂製パレットを前方側へ移動させていた。
【０００６】
従来の合成樹脂製パレットを前方へ移動させるには、フォーク部先端をフォーク挿入孔の側方に位置する桁部に当接させて押圧していた。つまり、合成樹脂製パレットをトラックの荷台に載置した後に、フォークリフトをバックさせてフォーク挿入孔からフォーク部を抜き出し、フォーク部が桁部に当接するようにフォークリフトを横方向に移動させたりしてフォーク部の幅方向の位置を調整した後、再度前進させて桁部にフォーク部先端を当接させて押圧していた。このように合成樹脂製パレットの押進作業は、多くの時間と労力を要するものであった。
【０００７】
また、フォーク部の幅方向の移動範囲が制限されているために、フォーク部先端を合成樹脂製パレットの両端に位置する端側桁部に当接するように、フォーク部の間隔を調整できないことがあった。この場合には、合成樹脂製パレットのフォーク挿入孔の間に位置する中央桁部のみを押圧するか、前記中央桁部と前記端側桁部とを押圧することになる。すると、合成樹脂製パレットをバランスよく押圧することができずに、押圧方向に対して合成樹脂製パレットが傾き、合成樹脂製パレットを所定の位置に移動できなくなるといった問題や合成樹脂製パレット上の荷物が崩れてしまうといった問題があった。
【０００８】
このような問題を解決すべく、特許第２８８０６５７号公報は、合成樹脂製パレットにフォーク部先端を係止するフォーク係止部を設けた合成樹脂製パレットを開示している。この合成樹脂製パレットの上面板状部は下面板状部よりも大きく、上面板状部が側面から大きく突出しており、フォーク係止部をなす。このフォーク係止部は、フォーク部先端が突き当たる前方当接面とフォーク部が上方に位置ずれすることを防止する上方当接面とを具備する。
【０００９】
この構成を具備する合成樹脂製パレットにあっては、フォーク係止部にフォーク先端を突き当ててバランスよく押圧できるため、合成樹脂製パレット上の荷物を崩すことなく所定の位置に移動させることができる。
【発明の開示】
【発明が解決しようとする課題】
【００１０】
ところが、上記フォーク係止部を具備する合成樹脂製パレットでは、フォーク係止部が大きく突出された上面部に形成されているので、フォーク係止部の強度が確保できず、フォーク部で押圧した際に破損してしまうおそれがあった。
また、合成樹脂製パレットを押圧している際に、フォーク部がフォーク係止部の下側に位置するフォーク挿入孔へ外れた場合には、フォークリフトが合成樹脂製パレットに衝突して合成樹脂製パレット上の荷物がくずれてしまうおそれがあった。
さらに、上面板状部が側面から大きく突出しているために、合成樹脂製パレットを並列に配置できる数が制限されてしまい、トラックの荷台や倉庫内への合成樹脂製パレットの収容数が減少してしまうといった問題もあった。
【００１１】
本発明は、このような実情に鑑みてなされたものであって、フォークリフト等を用いて簡単にかつ確実に前方に押出すことができるとともに、トラックの荷台や倉庫内への収容数が無用に制限されない合成樹脂製パレットを提供することを目的とする。
【課題を解決するための手段】
【００１２】
本発明の合成樹脂製パレットは、互いに対向して配置された上面板状部及び下面板状部と、これら上面板状部と下面板状部との間の外周を囲む側面部とを有し、該側面部には少なくとも一対のフォーク挿入孔の開口部が形成された合成樹脂製パレットであって、
前記フォーク挿入孔の前記開口部上方には、前記合成樹脂製パレットの内側に向けて凹んだフォーク押圧部が形成され、該フォーク押圧部は、フォークリフトのフォーク部によって押圧される押圧面と、前記フォーク部の上方への移動を規制する上方ガイド部と、前記フォーク部の下方への移動を規制する下方ガイド部と、前記フォーク部の側方への移動を規制する側方ガイド部とを有することを特徴としている。
【発明の効果】
【００１３】
本発明に係る合成樹脂製パレットによれば、フォーク挿入孔の開口部上方に、合成樹脂製パレットの内側に凹んだフォーク押圧部が設けられているので、このフォーク押圧部をフォークリフト等のフォーク部先端で押圧することによって合成樹脂製パレットを押進させることができる。
また、このフォーク押圧部にはフォーク部の下方への移動を規制する下方ガイド部が設けられているので、押進作業中にフォーク部がフォーク挿入孔に外れてしまうことを防止でき、フォークリフト等が不意に合成樹脂製パレットに衝突するおそれがなく、合成樹脂製パレット上の荷物が崩れてしまうことを防止できる。
【００１４】
また、フォーク押圧部にはフォーク部の側方への移動を規制する側方ガイド部が設けられているので、フォーク部が横に滑ってしまった場合でも、フォーク部が外れることがなく合成樹脂製パレットを安定して押進することができる。
さらに、フォーク押圧部が合成樹脂製パレットの内側に向けて凹むように形成されており、上面板状部が側面から大きく突出していないので、合成樹脂製パレットを並列に配置できる数が無用に制限されず、トラックの荷台や倉庫内への合成樹脂製パレットの収容数が減少することがない。また、上面板状部に大きく突出した部分がないので、合成樹脂製パレットの取り扱いが簡単となる。
【００１５】
このように本発明によれば、フォークリフト等による合成樹脂製パレットの押進作業を簡単にかつ確実に行うことができるとともに、トラックの荷台や倉庫内への合成樹脂製パレットの収容数が無用に制限されない合成樹脂製パレットを提供することができる。

このように構成された合成樹脂製パレット１１の桁部１４の間には、フォークリフトやパレットリフトのフォーク部を挿入するための二対のフォーク挿入孔２１、２１、又は２２、２２が形成されている。長辺方向に延びる一対のフォーク挿入孔２１、２１は、短辺側の両側面部１５に開口部２１Ａ、２１Ａを有する。短辺方向に延びる一対のフォーク挿入孔２２、２２は、長辺側の両側面部１５に開口部２２Ａ、２２Ａを有する。すなわち、図面に表された合成樹脂パレットは、いわゆる四方差しの合成樹脂製パレット１１である。つまり、桁部１４とフォーク挿入孔２１および２１の開口部２１Ａおよび２１Ａとにより構成された短辺側側面部１５と、桁部１４とフォーク挿入孔２２および２２の開口部２２Ａおよび２２Ａとにより構成された長辺側側面部１５とを接触させて配置することにより、合成樹脂製パレット１１の側面部１５を形成している。そしてこの側面部１５は、上面板状部１２と下面板状部１３との外周部分を囲んでいる。
【００２１】
下面板状部１３において、フォーク挿入孔２１および２１の底部をなす領域、つまり桁部１４と桁部１４との間にはフォークリフトやパレットトラックのフォーク部の挿入方向に直行する方向に沿って複数の桟部２３および２３が互いに間隔をあけて設けられている。同様に、フォーク挿入孔２２および２２の底部をなす領域、つまり桁部１４と桁部１４との間にはフォーク部の挿入方向に直行する方向に沿って複数の桟部２４および２４が互いに間隔をあけて設けられている。
ここで、短辺側側面部１５に開口部２１Ａおよび２１Ａが設けられたフォーク挿入孔２１、２１の底部に配置された桟部２３の高さは、長辺側側面部１５に開口部２２Ａおよび２２Ａが設けられたフォーク挿入孔２２、２２の底部に配置された桟部２４の高さよりも低くなるように設定されている。
【００２２】
また、下面板状部１３には桁部１４の間の領域には、フォーク挿入孔２１および２１に連通する複数の車輪用孔２５が形成されている。パレットトラックをフォーク挿入孔２１および２１に挿入した場合、パレットトラックの車輪が車輪用孔２５を介して、接地できる。
なお、本具体例の合成樹脂パレット１１では、車輪用孔２５が４つ形成されているため、桟部２３および２４によって下面板状部１３は中心に十字が形成された四角形状を有する。
【００２３】
図２および図３に示すように、フォーク挿入孔２１、２１、又は２２、２２の開口部２１Ａ、２１Ａ、又は２２Ａ、２２Ａと上面板状部１２との間の部分には、フォーク押圧部３１が形成されている。このフォーク押圧部３１は、フォーク挿入孔２１、２１、又は２２、２２が延びる方向に凹んでいる。図５に示すように、このフォーク押圧部３１は、上面板状部１２に対して垂直に、かつ側面部１５に対して概略平行に延びる平面状の底面部を具備する。この底面部はフォークリフトのフォーク部先端が当接される押圧面３２とされている。この押圧面３２の上方に位置する上面板状部１１が上方ガイド部３３とされ、押圧面３２の下方に位置するフォーク挿入孔２１、２１、又は２２、２２の上方壁面が下方ガイド部３４とされている。
［００２４］
これらフォーク挿入孔２１、２１、又は２２、２２の上方壁面と上面板状部１１とを連結するように、かつ押圧面３２から垂直に立ち上がるように延びる一対の側方ガイド部３５が形成されている。より詳細には、図２および図３に示すように、フォーク挿入孔２１、２１、２２、および２２の上であって、その側壁面と他の側壁面との間にフォーク押圧部３１が形成されている。
言い換えれば、開口部２１Ａ、２１Ａ、又は２２Ａ、２２Ａの上壁面に沿って、くぼんだフォーク押圧部３１が形成され、押圧面３２から立設するように一対の側方ガイド３５が形成されている。
［００２５］
さらに、側方ガイド部３５の裏側部分には、図２、図３、図６に示すように、補強用リブ３６が上面板状部１１と平行に延びるように、かつ押圧面３２から垂直に突出するように形成されている。
また、押圧面３２の裏側には、図４に示すように補強用リブ３７が、押圧面３２に対して垂直に延びるように複数形成されている。
［００２６］
合成樹脂製パレット１１の上面、つまり上面板状部１２の表面は、各種荷物を積載するための積載面を構成しており、荷物を安定した状態で載せることができるように平坦に形成されている。そしてこの上面板状部１２の四辺の各縁部には、上方に突出した突起部３８が設けられている。パレットを重ねた場合、上面板状部１２の突起部３８と相対する下面板状部１３の部分には、突起部３８を収容できる溝が設けられている。このように上面板状部１２の四辺の各縁部に上方に突出した突起部３８を設け、下面板状部１３にはそれを収容できる溝を設けることにより、パレットを位置ずれなく安定して重ねることができる。
［００２７］
このような構成とされた合成樹脂製パレット１１は、上面板状部１２の表面に荷物を載せた状態で、一対のフォーク挿入孔２１、２１、又は２２、２２にフォークリフトやパレットトラックのフォーク部を挿入して合成樹脂製パレット１１ごとトラックの荷台や倉庫に載置することにより、荷物をまとめて運搬および保管するものである。
［００２８］
例えば長辺側に開口するフォーク挿入孔２２、２２には、フォークリフトのフォーク部が挿入され、合成樹脂製パレット１１が運搬される。
一方、短辺側に開口部２１Ａ、２１Ａを有するフォーク挿入孔２１、２１には、先に説明したように、高さの低い桟部２３が設けられている。このため、フォーク部の先端付近に車輪等が設けられたパレットトラックであっても、先端部付近の車輪等が容易に桟部２３を乗り越える。このため車輪用孔２５を介してパレットトラックの車輪が床面と接地し、パレットトラックでパレットを運搬できる。
つまり、長辺側に開口したフォーク挿入孔２２、２２は、フォークリフトによる運搬に使用に好適であり、短辺側に開口したフォーク挿入孔２１、２１は、フォークリフト及びパレットトラックによる運搬に使用され、特にパレットトラックによる運搬に好適に使用される。
【００２９】
前記の合成樹脂製パレット１１をフォークリフトのフォーク部先端で押圧して移動させる押進作業は次のように行われる。
合成樹脂製パレット１１のフォーク挿入孔２１、２１、又は２２、２２にフォークリフトのフォーク部を差し込んで運搬して、一旦、合成樹脂製パレット１１をトラックの荷台等に載置した後にフォークリフトをバックさせてフォーク部を抜き出す。フォーク部を上方に移動させた後にフォークリフトを前進させて、フォーク部先端をフォーク押圧部３１に挿入して押圧面３２に当接させる。この状態でフォークリフトを前進させることにより、合成樹脂製パレット１１を押進させるのである。
【００３０】
この合成樹脂製パレット１１では、フォーク挿入孔２１、２１、又は２２、２２の上方にフォーク押圧部３１が設けられており、このフォーク押圧部３１にフォーク部先端を挿入して押圧面３２を押圧することによって押進させることができるので、フォークリフトをバックさせてフォーク部の高さを調整するのみで合成樹脂製パレット１１を押進させることができる。したがって、フォークリフトやフォーク部を横方向移動させることなく、押進作業を簡単に行うことができる。
【００３１】
また、フォーク部先端が当接される押圧面３２の裏側に複数の補強用リブ３７が形成されて強度が確保されているので、フォーク部先端で押圧した際に、押圧面３２が破損することを防止できる。
また、フォーク部の下方への移動を防止するための下方ガイド部３４が設けられているので、合成樹脂製パレット１１を押圧している際に、フォーク部がフォーク挿入孔２１、２１又は２２、２２へ外れることを防止でき、不意にフォークリフトが合成樹脂製パレット１１に衝突することを防止できる。
【００３２】
また、フォーク部の側方への移動を防止するための側方ガイド部３５が形成されているので、フォーク部が滑って横方向にずれることを防止でき、合成樹脂製パレット１１を安定して押圧することができる。
さらに、フォーク部の上方への移動を防止するための上方ガイド部３３が設けられているので、押進作業中にフォーク部が外れて合成樹脂製パレット１１上の荷物を傷つけることを防止できる。
【００３３】
また、上面板状部１２と下面板状部１３とが略同じ面積とされており、上面板状部１２が外側に大きく突出していないので、合成樹脂製パレット１１を並べた場合にもトラックの荷台や倉庫内への合成樹脂製パレット１１の収容数が減少することがない。
さらに、側方ガイド部３５の裏側に補強用リブ３６が形成されて強度が確保されているので、フォーク部が側方ガイド部３５に衝突した際の衝撃による破損を防止することができる。
【００３４】
以上、本発明の実施例による合成樹脂製パレットについて説明したが、本発明は前記した実施例に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。
例えば、フォーク挿入孔が２方向から合成樹脂製パレットを貫通して４方向からフォーク部を差し込むことができる、いわゆる四方差しの合成樹脂製パレットとして説明したが、フォーク挿入孔が合成樹脂製パレットを貫通して２方向からフォーク部を差し込むことができる、いわゆる二方差しの合成樹脂製パレットであってもよい。
【産業上の利用可能性】
【００３５】
本発明によれば、フォークリフト等による合成樹脂製パレットの押進作業を簡単にかつ確実に行うことができるとともに、トラックの荷台や倉庫内への合成樹脂製パレットの収容数が無用に制限されない合成樹脂製パレットを提供することができる。【Technical field】

The present invention relates to a synthetic resin pallet used when transporting and storing various cargoes, and relates to a synthetic resin pallet that can be transported by a forklift or a pallet truck.
[Background]
[0002]
In general, a pallet made of synthetic resin formed by injecting synthetic resin is provided as a pallet used when carrying and storing luggage. For example, Japanese Patent Laid-Open Nos. 2001-72063 and 2000-16430 disclose a two-way synthetic resin pallet into which a fork portion such as a disclosed forklift can be inserted from two directions, and a four-way synthetic resin to be inserted from four directions. A pallet made of steel is disclosed.
[0003]
This kind of synthetic resin pallet includes an upper surface plate-shaped portion and a lower surface plate-shaped portion arranged in parallel to each other, and a girder portion that connects the upper surface plate-shaped portion and the lower surface plate-shaped portion. The upper plate-like portion and the lower plate-like portion are connected to each other by girders arranged at both ends and in the middle, and a pair of fork insertion holes is provided between the upper plate-like portion and the lower-face plate-like portion. Is formed. That is, the girder part and the opening part of the fork insertion hole are provided in the side part surrounding the outer peripheral part of the upper surface plate part and the lower surface plate part.
[0004]
Synthetic resin pallets are used to transport and store packages in bulk. Specifically, a forklift or a fork part of a pallet truck is inserted into a pair of fork insertion holes with a load placed on the upper surface thereof, and the synthetic resin pallet is placed on the truck bed or warehouse.
[0005]
However, when a plurality of synthetic resin pallets are placed in a column in a track where only the rear portion of the loading platform is opened and the depth of the loading platform is sufficiently long relative to the length of the fork portion, the rear of the loading platform Since it is loaded from the side, the synthetic resin pallet cannot be placed on the front side of the loading platform.
In this way, when the synthetic resin pallet cannot be placed in a desired place with the fork part such as a forklift inserted in the fork insertion hole, the side part of the synthetic resin pallet is pressed with the fork part tip of the forklift or the like. The plastic pallet was moved forward.
[0006]
In order to move the conventional synthetic resin pallet forward, the front end of the fork part is pressed against the girder located on the side of the fork insertion hole. In other words, after placing the plastic pallet on the truck bed, back the forklift, pull out the fork from the fork insertion hole, and move the forklift laterally so that the fork is in contact with the girder. After adjusting the position of the fork portion in the width direction, the fork portion was advanced again and the fork portion tip was brought into contact with the girder and pressed. As described above, the pushing operation of the synthetic resin pallet requires a lot of time and labor.
[0007]
In addition, since the range of movement of the fork portion in the width direction is limited, the distance between the fork portions cannot be adjusted so that the tip of the fork portion comes into contact with the end side beam portions located at both ends of the synthetic resin pallet. there were. In this case, only the central beam part located between the fork insertion holes of the synthetic resin pallet is pressed, or the center beam part and the end side beam part are pressed. Then, the synthetic resin pallet cannot be pressed in a well-balanced manner, and the synthetic resin pallet is inclined with respect to the pressing direction, and the synthetic resin pallet cannot be moved to a predetermined position. There was a problem that the luggage collapsed.
[0008]
In order to solve such a problem, Japanese Patent No. 2880657 discloses a synthetic resin pallet provided with a fork locking portion for locking the tip of the fork portion on the synthetic resin pallet. The upper surface plate-like portion of the synthetic resin pallet is larger than the lower surface plate-like portion, and the upper surface plate-like portion protrudes greatly from the side surface to form a fork locking portion. The fork locking portion includes a front abutting surface on which the tip of the fork portion abuts and an upper abutting surface that prevents the fork portion from being displaced upward.
[0009]
In the synthetic resin pallet having this configuration, the fork tip can be abutted against the fork locking portion and pressed in a balanced manner, so that the load on the synthetic resin pallet can be moved to a predetermined position without breaking. it can.
DISCLOSURE OF THE INVENTION
[Problems to be solved by the invention]
[0010]
However, in the synthetic resin pallet provided with the fork locking portion, the fork locking portion is formed on the upper surface portion that protrudes greatly, so that the strength of the fork locking portion cannot be ensured and is pressed by the fork portion. There was a risk of damage.
Also, if the fork part comes off to the fork insertion hole located below the fork locking part while pressing the synthetic resin pallet, the forklift collides with the synthetic resin pallet and There was a risk that the load on the pallet would collapse.
Furthermore, since the top plate-shaped part protrudes greatly from the side surface, the number of synthetic resin pallets that can be arranged in parallel is limited, and the number of synthetic resin pallets that can be placed in the truck bed or warehouse is reduced. There was also a problem such as.
[0011]
The present invention has been made in view of such circumstances, and can be easily and reliably pushed forward using a forklift or the like, and the number of trucks loaded in the loading platform or warehouse is unnecessary. An object is to provide a plastic pallet that is not restricted.

[0023]
As shown in FIG. 2 and FIG. 3, the fork pressing portion 31 is provided in a portion between the opening 21 </ b> A, 21 </ b> A, or 22 </ b> A, 22 </ b> A of the fork insertion hole 21, 21, 22, 22 and the upper plate member 12. Is formed. The fork pressing portion 31 is recessed in the direction in which the fork insertion holes 21, 21, 22, 22 extend. As shown in FIG. 5, the fork pressing portion 31 includes a planar bottom surface portion that extends perpendicularly to the upper surface plate-shaped portion 12 and substantially parallel to the side surface portion 15. The bottom surface portion is a pressing surface 32 against which the fork lift tip of the forklift comes into contact. The upper plate portion 11 located above the pressing surface 32 is the upper guide portion 33, and the upper wall surface of the fork insertion holes 21, 21, 22, 22 located below the pressing surface 32 is the lower guide portion 34. Has been.
[0024]
A pair of side guide portions 35 are formed so as to connect the upper wall surface of the fork insertion holes 21, 21, 22, 22 and the upper surface plate-like portion 11, and extend vertically from the pressing surface 32. Yes. More specifically, as shown in FIGS. 2 and 3, a fork pressing portion 31 is formed on the fork insertion holes 21, 21, 22, and 22 between the side wall surface and the other side wall surface. Has been.
In other words, a recessed fork pressing portion 31 is formed along the upper wall surface of the openings 21A, 21A, or 22A, 22A, and a pair of side guides 35 are formed so as to stand from the pressing surface 32. .
[0025]
Further, as shown in FIGS. 2, 3, and 6, the reinforcing ribs 36 extend in parallel to the upper surface plate-like portion 11 and are perpendicular to the pressing surface 32 on the back side portion of the side guide portion 35. It is formed to protrude.
Further, as shown in FIG. 4, a plurality of reinforcing ribs 37 are formed on the back side of the pressing surface 32 so as to extend perpendicularly to the pressing surface 32.
[0026]
The upper surface of the synthetic resin pallet 11, that is, the surface of the upper plate-like portion 12 constitutes a loading surface for loading various loads, and is formed flat so that the loads can be loaded stably. Yes. Projections 38 projecting upward are provided at each edge of the four sides of the upper surface plate-like portion 12. When the pallets are stacked, a groove that can accommodate the protruding portion 38 is provided in the portion of the lower surface plate-like portion 13 that faces the protruding portion 38 of the upper surface plate-like portion 12. In this way, the protrusions 38 projecting upward are provided at the respective edges of the four sides of the upper surface plate-like portion 12, and the lower surface plate-like portion 13 is provided with a groove capable of accommodating it, so that the pallet can be stably positioned.

The synthetic resin pallet 11 having such a configuration has a fork lift or a pallet truck fork portion in a pair of fork insertion holes 21, 21, 22, 22 with a load placed on the surface of the upper plate 12. And the synthetic resin pallet 11 is placed on a truck bed or a warehouse to transport and store the packages together.
[0028]
For example, the fork portion of the forklift is inserted into the fork insertion holes 22 opened on the long side, and the synthetic resin pallet 11 is transported.
On the other hand, as described above, the fork insertion holes 21 and 21 having the openings 21A and 21A on the short side are provided with the crosspieces 23 having a low height. For this reason, even in the case of a pallet truck provided with wheels or the like in the vicinity of the tip of the fork portion, the wheel or the like in the vicinity of the tip easily gets over the crosspiece 23. For this reason, the wheel of a pallet truck contacts the floor via the wheel hole 25, and the pallet can be transported by the pallet truck.
That is, the fork insertion holes 22 and 22 opened on the long side are suitable for use in transportation by a forklift, and the fork insertion holes 21 and 21 opened on the short side are used for transportation by a forklift and a pallet truck. In particular, it is suitably used for transportation by a pallet truck.
[0029]
The pushing operation of pressing and moving the synthetic resin pallet 11 at the tip of the fork portion of the forklift is performed as follows.
The fork lift fork is inserted into the fork insertion holes 21, 21, 22, 22 of the synthetic resin pallet 11 and transported. After the synthetic resin pallet 11 is placed on the truck bed etc., the forklift is moved back. And pull out the fork part. After the fork part is moved upward, the forklift is advanced, and the tip of the fork part is inserted into the fork pressing part 31 and brought into contact with the pressing surface 32. In this state, the synthetic resin pallet 11 is pushed forward by advancing the forklift.
[0030]
In this synthetic resin pallet 11, a fork pressing portion 31 is provided above the fork insertion holes 21, 21, 22, 22, and the fork pressing portion 31 is inserted into the fork pressing portion 31 to press the pressing surface 32. Therefore, the synthetic resin pallet 11 can be pushed only by adjusting the height of the fork portion by backing the forklift. Accordingly, the pushing operation can be easily performed without moving the forklift or the fork portion in the lateral direction.
[0031]
In addition, since a plurality of reinforcing ribs 37 are formed on the back side of the pressing surface 32 with which the tip of the fork portion comes into contact, and the strength is ensured, the pressing surface 32 is damaged when pressed with the tip of the fork portion. Can be prevented.
Moreover, since the lower guide part 34 for preventing the downward movement of the fork part is provided, when the synthetic resin pallet 11 is pressed, the fork part has the fork insertion holes 21, 21 or 22, The forklift can be prevented from colliding with the synthetic resin pallet 11 unexpectedly.
[0032]
Moreover, since the side guide part 35 for preventing the fork part from moving to the side is formed, the fork part can be prevented from slipping and shifting in the lateral direction, and the synthetic resin pallet 11 can be stabilized. Can be pressed.
Furthermore, since the upper guide portion 33 for preventing the fork portion from moving upward is provided, it is possible to prevent the fork portion from being detached and damaging the load on the synthetic resin pallet 11 during the pushing operation.
[0033]
Further, since the upper surface plate-like portion 12 and the lower surface plate-like portion 13 have substantially the same area, and the upper surface plate-like portion 12 does not protrude greatly to the outside, even when the synthetic resin pallets 11 are arranged, There is no reduction in the number of synthetic resin pallets 11 accommodated in the loading platform or warehouse.
Furthermore, since the reinforcing rib 36 is formed on the back side of the side guide portion 35 to ensure the strength, it is possible to prevent damage due to impact when the fork portion collides with the side guide portion 35.
