Description

本発明は、ラック倉庫における積荷用のパレットに関する。   The present invention relates to a pallet for loading in a rack warehouse.

ラック倉庫では、複数のラックが並設されており、これらのラックにはパレットを介して荷物が載置されている。
ラック倉庫に対して地震時等による大きな水平力が作用すると、ラックに積載された積荷に荷崩れが生じるおそれがある。このような荷崩れは、荷物そのものの損傷だけではなく、周辺機器の損壊を引き起こす場合がある。
そのため、ラック倉庫内での荷崩れ防止を目的として、ラック倉庫の制振化または免震化を行う場合がある。ところが、建物（倉庫）自体を制振化または免震化する場合は、大規模な工事が必要となり、手間と費用がかかる。 In the rack warehouse, a plurality of racks are arranged side by side, and luggage is placed on these racks via pallets.
When a large horizontal force is applied to the rack warehouse due to an earthquake or the like, the load loaded on the rack may collapse. Such a collapse of the load may cause not only damage to the package itself but also damage to peripheral devices.
For this reason, there is a case where the rack warehouse is subjected to vibration control or seismic isolation for the purpose of preventing load collapse in the rack warehouse. However, if the building (warehouse) itself is to be damped or seismically isolated, a large-scale construction is required, which takes time and money.

これに対し、本出願人等は、例えば、特許文献１に示すように、ラックのパレット載置部に設ける制振装置として、水平方向の揺れを吸収し、ラックに積載された荷物の落下を防止する制振装置を開発した。
また、特許文献２には、内蔵された免震層によって水平方向の揺れを吸収することで上載された荷物の落下を防止するパレットが開示されている。 On the other hand, the present applicants, for example, as shown in Patent Document 1, as a vibration damping device provided in a rack pallet mounting portion, absorbs horizontal shaking and causes the load loaded on the rack to fall. Developed a damping device to prevent.
Patent Document 2 discloses a pallet that prevents falling of the loaded cargo by absorbing horizontal shaking by a built-in seismic isolation layer.

特開２０１３−１８０８７０号公報JP 2013-180870 A 特開２０１５−０９８３３５号公報Japanese Patent Laying-Open No. 2015-098335

大規模なラック倉庫において各ラックに制震装置を設置するには手間がかかる。また、複雑な構造を備える制振装置が多数必要となるため費用もかかる。また、免震層を備えたパレットも単価が高く、パレットが多数必要なラック倉庫に採用するには高価であった。
このような観点から、本発明は、簡易な構造でかつ安価な積荷の落下防止用のパレットを提案することを課題とする。 It takes time and effort to install a vibration control device in each rack in a large-scale rack warehouse. Moreover, since many damping devices provided with a complicated structure are needed, it also costs. Also, pallets with seismic isolation layers are expensive and expensive to use in rack warehouses that require a large number of pallets.
From such a viewpoint, an object of the present invention is to propose a pallet for preventing falling of a load with a simple structure and at a low cost.

前記課題を解決するための本発明は、下部材と、前記下部材に載置された上部材と、を備えるパレットであって、前記上部材は、前記下部材に対して一方向のみに移動することが可能に当該下部材に係合されており、常時は前記下部材の下面と前記上部材の上面とが平行で、前記上部材が前記一方向に移動した際は当該上部材の上面の前記一方向側の端部がその反対側の端部よりも低くなるように傾斜することを特徴としている。
かかるパレットに対して、地震時等の水平力が作用することで上板が下板に対して一方向に移動すると、上板の一方向側が他方向側よりも低くなるように傾斜した状態となる。そのため、パレットに上載された積荷が、他方向側にすべり出ることが防止され、ひいては荷崩れが防止される。ここで、パレットは、下部材とラック（腕木）との摩擦係数よりも、下部材と上部材との摩擦係数の方が小さくなるように構成することで、水平力が作用した際に上板のみが他方向側に移動するようにする。 The present invention for solving the above problems is a pallet comprising a lower member and an upper member placed on the lower member, wherein the upper member moves only in one direction relative to the lower member. The lower member is normally engaged with the lower member so that the lower surface of the lower member is parallel to the upper surface of the upper member, and the upper surface of the upper member is moved when the upper member moves in the one direction. It is characterized by inclining so that the end portion on the one direction side is lower than the end portion on the opposite side.
When the upper plate moves in one direction relative to the lower plate due to a horizontal force acting during an earthquake or the like on such a pallet, the pallet is inclined so that one direction side of the upper plate is lower than the other direction side. Become. As a result, the load placed on the pallet is prevented from slipping out in the other direction, thereby preventing the collapse of the load. Here, the pallet is configured such that the coefficient of friction between the lower member and the upper member is smaller than the coefficient of friction between the lower member and the rack (arms), so that the upper plate when a horizontal force is applied. Only move in the other direction.

前記下部材は、下板と、前記下板から上向きに突出する複数の下側支持部材とを備えており、前記上部材は、上板と、前記上板から下向きに突出する複数の上側支持部材とを備えており、前記下側支持部材が少なくとも前記下板の四隅に形成されていて、前記上側支持部材が少なくとも前記上板の四隅に形成されており、前記複数の下側支持部材のうちの少なくとも一つには前記一方向側に開口する下側係合部が形成されており、前記複数の上側支持部材のうちの少なくとも一つには前記下側係合部に抜け出し可能に挿入された上側係合部が形成されていればよい。
また、前記下側係合部が前記下板の四隅に形成された前記下側支持部材に形成されており、前記上側係合部が前記上板の四隅に形成された前記上側支持部材に形成されていて、前記下側支持部材および前記上側支持部材は上下方向の圧縮力および引張力を伝達可能に係合されているのが望ましい。 The lower member includes a lower plate and a plurality of lower support members that protrude upward from the lower plate, and the upper member includes an upper plate and a plurality of upper supports that protrude downward from the upper plate. The lower support member is formed at least at the four corners of the lower plate, the upper support member is formed at at least the four corners of the upper plate, and the plurality of lower support members At least one of them is formed with a lower engaging portion that opens in the one-direction side, and at least one of the plurality of upper support members is inserted in the lower engaging portion so as to be removable. What is necessary is just to form the above-mentioned upper engaging part.
In addition, the lower engagement portion is formed on the lower support member formed at the four corners of the lower plate, and the upper engagement portion is formed on the upper support member formed at the four corners of the upper plate. The lower support member and the upper support member are preferably engaged so as to be able to transmit a compressive force and a tensile force in the vertical direction.

前記下板の少なくとも前記一方向側の角部に、切欠き部が形成されていれば、下側係合部から上側係合部が抜け出た際に、上側支持部材が下板から落下するため、上板の上面が傾斜した状態になる。
なお、前記下板の四隅に形成された前記下側支持部材の間に下側中間支持部材を備えており、前記上板の四隅に形成された前記上側支持部材の間に前記下側中間支持部材に上載された上側中間支持部材を備えていれば、上板が上載荷重によりたわむことを防止することができる。 If a notch is formed in at least one corner of the lower plate, the upper support member falls from the lower plate when the upper engagement portion comes out of the lower engagement portion. The upper surface of the upper plate is inclined.
A lower intermediate support member is provided between the lower support members formed at the four corners of the lower plate, and the lower intermediate support is provided between the upper support members formed at the four corners of the upper plate. If the upper intermediate support member mounted on the member is provided, it is possible to prevent the upper plate from being bent by the upper load.

As shown in FIGS. 3B and 4B, the stopper 6 is configured such that the dropped fifth upper support member 55 is caught when the upper plate 4 is displaced rearward. In addition, what is necessary is just to form the stopper 6 as needed.

図３（ａ）に示すように、第一下側係合部３７および第二下側係合部３８に第一上側係合部５７および第二上側係合部３８を挿入することにより下板２と上板４とを組み合わせる。また、下板２と上板４を組み合わせると、第一下側支持部材３１，３１の上面は、上板４の下面に当接する。
また、第三上側支持部材５３、第四上側支持部材５４、第五上側支持部材５５，５５および第六上側支持部材５６は、それぞれ第三下側支持部材３３、第四下側支持部材３４、第五下側支持部材３５，３５および第六下側支持部材３６にそれぞれ上載されている。そのため、上板４上に荷物を載置した荷重を、上側支持部材５および下側支持部材３を介して下板２へ伝達することが可能である。 As shown in FIG. 3A, the lower plate is obtained by inserting the first upper engagement portion 57 and the second upper engagement portion 38 into the first lower engagement portion 37 and the second lower engagement portion 38. 2 and the upper plate 4 are combined. When the lower plate 2 and the upper plate 4 are combined, the upper surfaces of the first lower support members 31 and 31 come into contact with the lower surface of the upper plate 4.
The third upper support member 53, the fourth upper support member 54, the fifth upper support members 55, 55, and the sixth upper support member 56 are respectively a third lower support member 33, a fourth lower support member 34, The fifth lower support members 35 and 35 and the sixth lower support member 36 are respectively mounted. Therefore, it is possible to transmit the load with the load placed on the upper plate 4 to the lower plate 2 via the upper support member 5 and the lower support member 3.

第一上側係合部５７および第二上側係合部３８は、第一下側係合部３７および第二下側係合部３８に後方から挿入されているため、上板４に後ろ向きの力が作用した際には、図３（ｂ）に示すように、第一上側係合部５７および第二上側係合部３８が第一下側係合部３７および第二下側係合部３８から抜け出す。このとき、前側の下側支持部材３の高さ寸法が後側の下側支持部材３の高さ寸法よりも大きいため、上板４は後側が低くなるように傾斜する。そのため、パレット１に上載された荷物は、パレット１の前側に落下することがない。   Since the first upper engagement portion 57 and the second upper engagement portion 38 are inserted into the first lower engagement portion 37 and the second lower engagement portion 38 from the rear side, a backward force is applied to the upper plate 4. 3B, the first upper engagement portion 57 and the second upper engagement portion 38 become the first lower engagement portion 37 and the second lower engagement portion 38 as shown in FIG. Get out of. At this time, since the height dimension of the lower support member 3 on the front side is larger than the height dimension of the lower support member 3 on the rear side, the upper plate 4 is inclined so that the rear side becomes lower. Therefore, the load placed on the pallet 1 does not fall to the front side of the pallet 1.

また、下板２と上板４とを組み合わせると、上側支持部材５が下側支持部材３の後面に当接するため、上板４が下板２に対して前側にずれることがない。
また、第一上側支持部材５１、第二上側支持部材５２およびと第五上側支持部材５５は、それぞれ第一下側支持部材３１、第二下側支持部材３２および第五下側支持部材３５の内側面に係止するように配設されているため、上板４が下板２に対して左右にずれることもない。
すなわち、上板４のずれが後方（一方向側）のみとなるように規制されているため、地震時等の横方向の力がパレット１（荷物）に作用した場合であっても、パレット１上の荷物がラックから落下することが防止されている。
さらに、上板４のずれは、ストッパ６により規制されるため、上板４が大幅にずれることはない。
フォークリフトによってパレット１を輸送する場合には、パレット１の開口部１０からフォークリフト爪を挿入すればよい。開口部１０からフォークリフト爪を挿入した状態で上昇させると、上板４が上昇するため、第一上側係合部５７および第二上側係合部３８に形成された段差と、鉤型部分３１ａおよび本体部３２ａに形成された段差とが係合し、輸送時の下板２と上板４とのずれが規制される。
また、スタッカークレーン等によってパレット１（下板２）の下面を支えてパレット１を輸送する際には、図５（ａ）に示すように、ロック機構８が下板２の上面から突出して上板４の後方への移動が規制されるため、上板４がずれることがない。 Further, when the lower plate 2 and the upper plate 4 are combined, the upper support member 5 comes into contact with the rear surface of the lower support member 3, so that the upper plate 4 does not shift forward with respect to the lower plate 2.
The first upper support member 51, the second upper support member 52, and the fifth upper support member 55 are respectively the first lower support member 31, the second lower support member 32, and the fifth lower support member 35. Since the upper plate 4 is disposed so as to be engaged with the inner side surface, the upper plate 4 is not displaced left and right with respect to the lower plate 2.
That is, since the displacement of the upper plate 4 is restricted to be only rearward (one direction side), even if a lateral force such as an earthquake acts on the pallet 1 (luggage), the pallet 1 The upper luggage is prevented from falling from the rack.
Further, since the displacement of the upper plate 4 is regulated by the stopper 6, the upper plate 4 is not significantly displaced.
When the pallet 1 is transported by a forklift, a forklift claw may be inserted from the opening 10 of the pallet 1. When the forklift claw is inserted from the opening 10 and lifted, the upper plate 4 is lifted, so that the step formed on the first upper engagement portion 57 and the second upper engagement portion 38, the saddle portion 31a, The step formed in the main body 32a is engaged, and the deviation between the lower plate 2 and the upper plate 4 during transportation is regulated.
Further, when the pallet 1 is transported while supporting the lower surface of the pallet 1 (lower plate 2) by a stacker crane or the like, the lock mechanism 8 protrudes from the upper surface of the lower plate 2 as shown in FIG. Since the backward movement of the plate 4 is restricted, the upper plate 4 is not displaced.

以上の通り、本実施形態のパレット１に対して地震時等の水平力が作用すると、上側係合部５７，５８が下側係合部３７，３８から抜け出して、上板４が下板２に対して後側（一方向側）に移動する。下側支持部材３は、前側が高く、後側が低く形成されているため、後側に移動した上板４は、前側（一方向の反対側）が後側（一方向側）よりも高くなるように傾斜した状態となる。そのため、パレット１に上載された積荷が前側にすべり出ることが防止され、ひいては荷崩れが防止される。なお、パレット１は、下部材１１とラック（腕木）との摩擦係数よりも、下部材１１と上部材１２との摩擦係数の方が小さくなるように構成されているため、下部材１１が上部材１２とともに後側に移動することが防止されている。
また、下板２の少なくとも後端に、下側支持部材３の位置に応じて切欠き２１が形成されているため、下側係合部３７，３８から上側係合部５７，５８が抜け出た際に、上側支持部材５が下板２から落下し、上板４の上面が傾斜した状態になる。
なお、下板２および上板４との間には、複数の下側支持部材３および上側支持部材５が形成されているため、上載荷重による上板４のたわみ（変形）も抑制されている。 As described above, when a horizontal force such as an earthquake acts on the pallet 1 of the present embodiment, the upper engagement portions 57 and 58 come out of the lower engagement portions 37 and 38, and the upper plate 4 is moved to the lower plate 2. Move to the rear side (one-way side). Since the lower support member 3 is formed such that the front side is high and the rear side is low, the upper plate 4 moved to the rear side is higher on the front side (opposite side in one direction) than on the rear side (one direction side). It will be in the state which inclined like this. Therefore, the load placed on the pallet 1 is prevented from slipping out to the front side, and thus collapse of the load is prevented. The pallet 1 is configured such that the friction coefficient between the lower member 11 and the upper member 12 is smaller than the friction coefficient between the lower member 11 and the rack (arm). Moving to the rear side together with the member 12 is prevented.
Further, since the notch 21 is formed at least at the rear end of the lower plate 2 in accordance with the position of the lower support member 3, the upper engagement portions 57 and 58 come out from the lower engagement portions 37 and 38. At this time, the upper support member 5 falls from the lower plate 2 and the upper surface of the upper plate 4 is inclined.
In addition, since the several lower side support member 3 and the upper side support member 5 are formed between the lower board 2 and the upper board 4, the bending | flexion (deformation) of the upper board 4 by an overload is also suppressed. .

On the other hand, when a backward force is applied to the upper member 12, the upper member 12 is shifted rearward with respect to the lower member 11 as shown in FIG. At this time, since the upper support member 5 falls from the lower support member 3 or the lower plate 2, the upper member 12 is inclined so that the rear side is lowered. Therefore, the load placed on the pallet 1 does not fall to the front side of the pallet 1.
Further, since the upper plate 12 is sandwiched between the left and right lower plates 2, 2, the upper member 12 does not shift from side to side with respect to the lower member 11.
That is, since the displacement of the upper member 12 is regulated to be only rearward (one direction side), even if a lateral force such as during an earthquake acts on the pallet 1 (luggage), the pallet 1 The upper luggage is prevented from falling from the rack.

以上の通り、本実施形態のパレット１に対して地震時等の水平力が作用すると、上部材１２が下部材１１に対して後側（一方向側）に移動する。後側に移動した上部材１２は、前側（一方向の反対側）が後側（一方向側）よりも高くなるように傾斜した状態となる。そのため、パレット１に上載された積荷が前側にすべり出ることが防止され、ひいては荷崩れが防止される。ここで、パレット１は、下部材１１と腕木との摩擦係数よりも、下部材１１と上部材１２との摩擦係数の方が小さくなるように構成されているため、上部材１２とともに下部材１１が後側に移動することが防止されている。
なお、下部材１１および上部材１２との間には、複数の下側支持部材３および上側支持部材５が形成されているため、上載荷重による上部材１２（上側板材４１）のたわみ（変形）も抑制されている。 As described above, when a horizontal force such as an earthquake acts on the pallet 1 of the present embodiment, the upper member 12 moves to the rear side (one direction side) with respect to the lower member 11. The upper member 12 moved to the rear side is inclined so that the front side (opposite side in one direction) is higher than the rear side (one direction side). Therefore, the load placed on the pallet 1 is prevented from slipping out to the front side, and thus collapse of the load is prevented. Here, since the pallet 1 is configured such that the friction coefficient between the lower member 11 and the upper member 12 is smaller than the friction coefficient between the lower member 11 and the arms, the lower member 11 together with the upper member 12 is configured. Is prevented from moving to the rear side.

第二上側支持部材５２の下端部には、前向きに突出する第二上側係合部５８が形成されている。第二上側係合部５８は、第一下側係合部３８と同形状に形成されている。下板２と上板４とを組み合わせる際には、第二上側係合部５８を第二下側支持部材３２の後方から第二下側係合部３８に挿入する。第二上側係合部５８を第二下側係合部３８に挿入すると、第二上側係合部５８の内側面が板状部３２ｂの側面に当接する。すなわち、左右の第二上側係合部５８，５８と第二下側係合部３８，３８とが係合することで、下板２に対する前方向および左右方向への上板４のずれが防止されている。また、第二上側係合部５８と第二下側係合部３８とが係合することで、上下方向の力の伝達が可能となる。
第二上側支持部材５２の前面には、上載部５２ａが一体に形成されている。上載部５２ａは、下板２と上板４とを組み合わせた際に、第二下側支持部材３２の板状部３２ｂの上面に上載される部分である。上載部５２ａを板状部３２ｂに載置すると、上載荷重を下板２に伝達することが可能となる。 The second upper support member 52 is erected at the rear end of the upper plate 4. The second upper support member 52 has a height equivalent to that of the first upper support member 51.
The rear end portion of the second upper support member 52 projects from the edge of the notch 21 when the lower plate 2 and the upper plate 4 are combined.
A second upper engagement portion 58 that protrudes forward is formed at the lower end portion of the second upper support member 52. The second upper engagement portion 58 is formed in the same shape as the first lower engagement portion 38. When combining the lower plate 2 and the upper plate 4, the second upper engagement portion 58 is inserted into the second lower engagement portion 38 from the rear of the second lower support member 32. When the second upper engagement portion 58 is inserted into the second lower engagement portion 38, the inner surface of the second upper engagement portion 58 comes into contact with the side surface of the plate-like portion 32b. That is, the right and left second upper engaging portions 58, 58 and the second lower engaging portions 38, 38 are engaged, thereby preventing the upper plate 4 from being displaced forward and laterally with respect to the lower plate 2. Has been. In addition, the second upper engagement portion 58 and the second lower engagement portion 38 are engaged with each other, so that a force in the vertical direction can be transmitted.
On the front surface of the second upper support member 52, an upper portion 52a is integrally formed. The upper portion 52 a is a portion that is placed on the upper surface of the plate-like portion 32 b of the second lower support member 32 when the lower plate 2 and the upper plate 4 are combined. When the upper portion 52a is placed on the plate-like portion 32b, the upper load can be transmitted to the lower plate 2.

第三上側支持部材５３は、板状に形成されている。第三上側支持部材５３の前面は、上板４の前面と面一である。また、第三上側支持部材５３は、第一上側支持部材５１と同じ高さを有していて、下板２と上板４とを組み合わせた際に、下面が下板２の上面に当接する。
なお、第三上側支持部材５３の形状は限定されるものではなく、第三下側支持部材３３の形状に応じて適宜形成すればよい。
この他の上部材１２の詳細は、第一の実施形態で示した内容と同様なため、詳細な説明は省略する。 The third upper support member 53 is formed in a plate shape. The front surface of the third upper support member 53 is flush with the front surface of the upper plate 4. The third upper support member 53 has the same height as the first upper support member 51, and the lower surface abuts on the upper surface of the lower plate 2 when the lower plate 2 and the upper plate 4 are combined. .
The shape of the third upper support member 53 is not limited, and may be appropriately formed according to the shape of the third lower support member 33.
Since the other details of the upper member 12 are the same as the contents shown in the first embodiment, the detailed description is omitted.

図８（ａ）に示すように、第一下側係合部３７および第二下側係合部３８に第一上側係合部５７および第二上側係合部３８を挿入することにより下板２と上板４とを組み合わせる。下板２と上板４を組み合わせると、第一下側支持部材３１，３１の上面および下面は、それぞれ上板４の下面および第一上側係合部５７，５７の上面に当接する。このように、第一下側支持部材３１および第一上側支持部材５１を、上下方向の圧縮力および引張力を伝達可能に係合することで、パレット１の開口部１０からフォークリフト爪を挿入してパレット１を輸送すること、およびパレット１に荷物を上載することが可能となる。なお、フォークリフト爪は、パレット１の左右の側面から挿入してもよい。
また、第三上側支持部材５３、第四上側支持部材５４、第五上側支持部材５５，５５および第六上側支持部材５６は、それぞれ第三下側支持部材３３、第四下側支持部材３４、第五下側支持部材３５，３５および第六下側支持部材３６にそれぞれ上載されている。そのため、上板４上に荷物を載置した荷重を、上側支持部材５および下側支持部材３を介して下板２へ伝達することが可能である。
さらに、ガード部材３９が上板４の前面を覆った状態となる。すなわち、パレット１の前面には、下側部材１１のみが露出した状態となる。そのため、フォークリフト爪をパレット１の開口部１０から挿入する際に、万が一パレット１の上部にフォークリフト爪が接触した場合であっても、上部材１２が後側に押されてずれることがない。 As shown in FIG. 8A, the lower plate is obtained by inserting the first upper engagement portion 57 and the second upper engagement portion 38 into the first lower engagement portion 37 and the second lower engagement portion 38. 2 and the upper plate 4 are combined. When the lower plate 2 and the upper plate 4 are combined, the upper and lower surfaces of the first lower support members 31 and 31 come into contact with the lower surface of the upper plate 4 and the upper surfaces of the first upper engaging portions 57 and 57, respectively. In this manner, the forklift pawl is inserted from the opening 10 of the pallet 1 by engaging the first lower support member 31 and the first upper support member 51 so as to transmit the compressive force and the tensile force in the vertical direction. Thus, the pallet 1 can be transported, and a load can be loaded on the pallet 1. The forklift pawls may be inserted from the left and right side surfaces of the pallet 1.
The third upper support member 53, the fourth upper support member 54, the fifth upper support members 55, 55, and the sixth upper support member 56 are respectively a third lower support member 33, a fourth lower support member 34, The fifth lower support members 35 and 35 and the sixth lower support member 36 are respectively mounted. Therefore, it is possible to transmit the load with the load placed on the upper plate 4 to the lower plate 2 via the upper support member 5 and the lower support member 3.
Further, the guard member 39 covers the front surface of the upper plate 4. That is, only the lower member 11 is exposed on the front surface of the pallet 1. Therefore, when inserting the forklift claw from the opening 10 of the pallet 1, even if the forklift claw comes into contact with the upper part of the pallet 1, the upper member 12 is not pushed and displaced.

第一上側係合部５７および第二上側係合部３８は、第一下側係合部３７および第二下側係合部３８に後方から挿入されているため、上板４に後ろ向きの力が作用した際には、第一上側係合部５７および第二上側係合部３８が第一下側係合部３７および第二下側係合部３８から抜け出す。このとき、前側の下側支持部材３の高さ寸法が後側の下側支持部材３の高さ寸法よりも大きいため、図８（ｂ）に示すように、上板４は後側が低くなるように傾斜する。そのため、パレット１に上載された荷物は、パレット１の前側に落下することがない。   Since the first upper engagement portion 57 and the second upper engagement portion 38 are inserted into the first lower engagement portion 37 and the second lower engagement portion 38 from the rear side, a backward force is applied to the upper plate 4. Acts, the first upper engagement portion 57 and the second upper engagement portion 38 come out of the first lower engagement portion 37 and the second lower engagement portion 38. At this time, since the height dimension of the lower support member 3 on the front side is larger than the height dimension of the lower support member 3 on the rear side, as shown in FIG. To tilt. Therefore, the load placed on the pallet 1 does not fall to the front side of the pallet 1.

また、下板２と上板４とを組み合わせると、上側支持部材５が下側支持部材３の後面に当接するため、上板４が下板２に対して前側にずれることがない。
また、第一上側支持部材５１、第二上側支持部材５２およびと第五上側支持部材５５は、それぞれ第一下側支持部材３１、第二下側支持部材３２および第五下側支持部材３５の内側面に係止するように配設されているため、上板４が下板２に対して左右にずれることもない。
すなわち、上板４のずれが後方（一方向側）のみとなるように規制されているため、地震時等の横方向の力がパレット１（荷物）に作用した場合であっても、パレット１上の荷物がラックから落下することが防止されている。
さらに、上板４のずれは、ストッパ６により規制されるため、上板４が大幅にずれることはない。 Further, when the lower plate 2 and the upper plate 4 are combined, the upper support member 5 comes into contact with the rear surface of the lower support member 3, so that the upper plate 4 does not shift forward with respect to the lower plate 2.
The first upper support member 51, the second upper support member 52, and the fifth upper support member 55 are respectively the first lower support member 31, the second lower support member 32, and the fifth lower support member 35. Since the upper plate 4 is disposed so as to be engaged with the inner side surface, the upper plate 4 is not displaced left and right with respect to the lower plate 2.
That is, since the displacement of the upper plate 4 is restricted to be only rearward (one direction side), even if a lateral force such as an earthquake acts on the pallet 1 (luggage), the pallet 1 The upper luggage is prevented from falling from the rack.
Further, since the displacement of the upper plate 4 is regulated by the stopper 6, the upper plate 4 is not significantly displaced.

以上の通り、本実施形態のパレット１に対して地震時等の水平力が作用すると、上側係合部５７，５８が下側係合部３７，３８から抜け出して、上板４が下板２に対して後側（一方向側）に移動する。下側支持部材３は、前側が高く、後側が低く形成されているため、後側に移動した上板４は、前側（一方向の反対側）が後側（一方向側）よりも高くなるように傾斜した状態となる。そのため、パレット１に上載された積荷が前側にすべり出ることが防止され、ひいては荷崩れが防止される。なお、パレット１は、下部材１１とラック（腕木）との摩擦係数よりも、下部材１１と上部材１２との摩擦係数の方が小さくなるように構成されているため、下部材１１が上部材１２の移動とともに後側に移動することが防止されている。
また、下板２の少なくとも後端に、下側支持部材３の位置に応じて切欠き２１が形成されているため、下側係合部３７，３８から上側係合部５７，５８が抜け出た際に、上側支持部材５が下板２から落下し、上板４の上面が傾斜した状態になる。
なお、下板２および上板４との間には、複数の下側支持部材３および上側支持部材５が形成されているため、上載荷重による上板４のたわみ（変形）も抑制されている。 As described above, when a horizontal force such as an earthquake acts on the pallet 1 of the present embodiment, the upper engagement portions 57 and 58 come out of the lower engagement portions 37 and 38, and the upper plate 4 is moved to the lower plate 2. Move to the rear side (one-way side). Since the lower support member 3 is formed such that the front side is high and the rear side is low, the upper plate 4 moved to the rear side is higher on the front side (opposite side in one direction) than on the rear side (one direction side). It will be in the state which inclined like this. Therefore, the load placed on the pallet 1 is prevented from slipping out to the front side, and thus collapse of the load is prevented. The pallet 1 is configured such that the friction coefficient between the lower member 11 and the upper member 12 is smaller than the friction coefficient between the lower member 11 and the rack (arm). The movement of the member 12 to the rear side is prevented together with the movement of the member 12.
Further, since the notch 21 is formed at least at the rear end of the lower plate 2 in accordance with the position of the lower support member 3, the upper engagement portions 57 and 58 come out from the lower engagement portions 37 and 38. At this time, the upper support member 5 falls from the lower plate 2 and the upper surface of the upper plate 4 is inclined.
In addition, since the several lower side support member 3 and the upper side support member 5 are formed between the lower board 2 and the upper board 4, the bending | flexion (deformation) of the upper board 4 by an overload is also suppressed. .
