Description

The present invention relates to a plastic pallet.

Various technologies have been proposed for the resin pallets. For example, the technology described in the following Patent Document 1 is a plastic pallet in which an upper deck board and a lower deck board are connected by a support part with a hollow structure, and the space surrounded by the support part and the upper and lower deck boards serves as a fork insertion port. The technology is characterized in that a closed reinforcing rib is provided over the entire height of the support part on the inside of the support wall of the part of the support part facing the fork insertion port.

Furthermore, the plastic pallet is characterized in that the reinforcing ribs are formed with a U-shaped cross section and, together with the support walls, form a hollow structure.

According to the description in the following Patent Document 1, in a plastic pallet, the reinforcing ribs extend over the height of the support columns and form a hollow structure together with the support walls, so they act to prevent deformation of the support walls. Furthermore, the parts of the U-shaped cross-section reinforcing ribs that connect with the support walls are provided in the direction of deformation of the support walls, so they are effective in preventing deformation. As a result, the plastic pallet reduces the amount of deformation of the deck board without increasing the thickness of the support walls.

Japanese Patent Application Publication No. 8-268430

However, since the U-shaped cross-section reinforcing ribs are provided independently in large numbers on the support wall facing the fork insertion port in one direction or the other, and each rib reinforces the support wall while being separated, there is room to further reduce the amount of deformation of the deck board.

The present invention was made in consideration of the above points, and aims to provide a plastic pallet that is more effective at suppressing the deflection of the upper and lower deck surfaces.

The invention according to claim 1 made to solve this problem is a resin pallet comprising a plurality of girder walls which are annular walls connecting upper and lower deck surfaces and have lattice ribs on the inside surrounded by the walls, the plurality of girder walls including a central girder wall arranged at the centre of both ends of the resin pallet in the short direction, a first intermediate girder wall arranged at the centre of both ends of the resin pallet in the longitudinal direction, and corner girder walls arranged at the four corners of the resin pallet, each lattice rib of the central girder wall and the first intermediate girder wall connects the upper and lower deck surfaces and comprises an annular inner wall arranged along the girder wall, and a reinforcing rib which is arranged between the girder wall and the inner wall along the girder wall and connects to both the upper and lower deck surfaces or has a wall height lower than the girder wall and inner wall and connects to one of the upper and lower deck surfaces, and the lattice rib of the second intermediate girder wall connects the upper and lower deck surfaces and is arranged along three sides of the second intermediate girder wall which is located inward from the outer edges of the upper and lower deck surfaces. and a reinforcing rib arranged between the second intermediate girder wall and the inner wall along the second intermediate girder wall and the inner wall, and connected to both the upper and lower deck surfaces or having a wall height lower than that of the second intermediate girder wall and the inner wall and connected to one of the upper and lower deck surfaces. The lattice rib of the corner girder wall connects the upper and lower deck surfaces, and is arranged in an L-shape in plan view by extending inside two sides of the corner girder wall located inward from the outer edges of the upper and lower deck surfaces, the inner wall having both ends connected respectively to two corner sides of the corner girder wall located on the outer edge sides of the upper and lower deck surfaces.

The invention of claim 2 is a resin pallet as described in claim 1, characterized in that each lattice rib of the central girder wall, the first intermediate girder wall, the second intermediate girder wall and the corner girder wall is provided with a connecting rib connecting the girder walls and the inner walls.

The invention according to claim 3 is the resin pallet according to claim 2, characterized in that the connecting rib has a wall height lower than the girder wall and the inner wall and connects to one of the upper and lower deck surfaces.

The invention according to claim 4 is the resin pallet according to claim 2, characterized in that the connecting ribs connect to both the upper and lower deck surfaces.

The invention according to claim 5 is the resin pallet according to claim 2, characterized in that the connecting rib has a first connecting region that is lower in wall height than the girder wall and the inner wall and connects to one of the upper and lower deck surfaces, and a second connecting region that connects to both the upper and lower deck surfaces.

In the plastic pallet of the invention according to claim 1, the periphery of the girder wall connecting the upper and lower deck surfaces is reinforced with an inner wall and reinforcing ribs that extend parallel to the girder wall on the inside of the girder wall, thereby increasing the bending rigidity of the girder wall against the load of the cargo. As a result, the plastic pallet of the invention according to claim 1 improves the effect of suppressing the deflection of the upper and lower deck surfaces.

In addition, when the reinforcing ribs are lower in height than the girder walls and inner walls and are connected to one of the upper and lower deck surfaces, they are lighter than when they are connected to both the upper and lower deck surfaces.

In the resin pallet of the invention according to claim 2, the girder wall and the inner wall are connected by connecting ribs, so the bending rigidity of the girder wall against the load of the cargo is further increased.

In the plastic pallet of the invention according to claim 3, the connecting ribs have a lower wall height than the girder walls and the inner walls, and are connected to one of the upper and lower deck surfaces, so that the bending rigidity of the girder walls against the load of the cargo is further increased while suppressing weight increase.

In the plastic pallet of the invention according to claim 4, the connecting ribs are connected to both the upper and lower deck surfaces, further increasing the bending rigidity of the girder walls against the load of the cargo.

The plastic pallet of the invention according to claim 5 has a first connecting region that is lower in height than the girder wall and the inner wall and connects to one of the upper and lower deck surfaces, and a second connecting region that connects to both the upper and lower deck surfaces, thereby achieving a balance between suppressing weight increase and improving the bending rigidity of the girder wall against the load of the cargo.

The following describes the resin pallet of the present invention based on the present embodiment, with reference to the drawings.

(1) Overview of the Resin Pallet As shown in Fig. 1, the resin pallet 1 of this embodiment has a substantially rectangular shape in a plan view. The direction of the symbol D1 indicates the up-down direction of the resin pallet 1. The direction of the symbol D2 indicates the length direction of the resin pallet 1. The direction of the symbol D3 indicates the width direction of the resin pallet 1. These points are the same in Figs. 2 to 9 described below. However, in Fig. 4, the vertical direction of the paper surface is the up-down direction D1.

The resin pallet 1 comprises upper and lower deck surfaces 3, 3, a central girder wall 5, corner girder walls 7, a first intermediate girder wall 9, and a second intermediate girder wall 11. Each deck surface 3 has multiple types of lattice ribs arranged in a checkerboard pattern. Between each deck surface 3, the central girder wall 5, corner girder walls 7, first intermediate girder wall 9, and second intermediate girder wall 11 are provided.

The central girder wall 5 is disposed in the center of the resin pallet 1. The corner girder walls 7 are disposed at the four corners of the resin pallet 1. The first intermediate girder wall 9 is disposed in the center of both ends of the resin pallet 1 in the length direction D2. The second intermediate girder wall 11 is disposed in the center of both ends of the resin pallet 1 in the width direction D3.

As a result, at both ends of the length direction D2 of the plastic pallet 1, on both sides of the first intermediate girder wall 9, an insertion hole 13 is formed between the first intermediate girder wall 9 and the corner girder wall 7. Similarly, at both ends of the width direction D3 of the plastic pallet 1, on both sides of the second intermediate girder wall 11, an insertion hole 13 is formed between the second intermediate girder wall 11 and the corner girder wall 7. Therefore, the plastic pallet 1 is a four-way insertion double-sided use type. Note that the plastic pallet 1 may also be a four-way insertion single-sided use type.

The resin pallet 1 is composed of a pair of pallet bodies 15A, 15B. Each pallet body 15A, 15B is the same item, and is integrated by being heat-welded while facing each other. As a result, each pallet body 15A, 15B becomes a resin pallet 1. Therefore, in each pallet body 15A, 15B, the central girder wall 5, corner girder wall 7, first intermediate girder wall 9, and second intermediate girder wall 11 have a height (distance in the vertical direction D1) that is half the height (distance in the vertical direction D1) of the resin pallet 1, and form a half-body shape.

As shown in FIG. 2, in each pallet body 15A, 15B, the halves of the central girder wall 5, corner girder wall 7, first intermediate girder wall 9, and second intermediate girder wall 11 are erected from the reverse side of the deck surface 3. Below, the central girder wall 5, corner girder wall 7, first intermediate girder wall 9, and second intermediate girder wall 11 will be described based on their respective halves.

(2) Overview of the Central Girder Wall As shown in Figs. 3 to 5, the half body of the central girder wall 5 includes an annular wall 21. In a plan view, the annular wall 21 is in the shape of a substantially rectangular ring with the length direction D2 being longer than the width direction D3. A lattice rib 23 is formed on the inside of the annular wall 21. In the lattice rib 23, a rib parallel to the length direction D2 and a rib parallel to the width direction D3 intersect with each other. The lattice rib 23 includes an inner wall 25, a reinforcing rib 27, a first connecting rib 29, and a second connecting rib 31.

The inner wall 25 is disposed along the annular wall 21 at a predetermined distance inside the annular wall 21, and forms a rectangular ring in a plan view. The wall height (distance in the vertical direction D1) of the inner wall 25 is the same as the wall height (distance in the vertical direction D1) of the annular wall 21.

The reinforcing rib 27 is disposed along the annular wall 21 and the inner wall 25 in the center between them, forming a rectangular ring in plan view. The wall height (distance in the vertical direction D1) of the reinforcing rib 27 is lower than the wall height (distance in the vertical direction D1) of the annular wall 21 and the inner wall 25.

The first connecting rib 29 and the second connecting rib 31 are provided between the annular wall 21 and the inner wall 25 in a form that crosses the reinforcing rib 27, and are arranged alternately at an equal pitch. The wall height (distance in the vertical direction D1) of the first connecting rib 29 is the same as the wall height (distance in the vertical direction D1) of the annular wall 21 and the inner wall 25. The first connecting rib 29 is connected to a part of the lattice rib 23 on the inside of the inner wall 25 via the inner wall 25.

The second connecting rib 31 has a first connecting region 31A and a second connecting region 31B. The first connecting region 31A is an area whose wall height (distance in the vertical direction D1) is lower than the wall height (distance in the vertical direction D1) of the inner wall 25, and extends from the inner wall 25 toward the reinforcing rib 27. In contrast, the second connecting region 31B is an area whose wall height (distance in the vertical direction D1) is the same as the wall height (distance in the vertical direction D1) of the annular wall 21, and extends from the annular wall 21 toward the reinforcing rib 27.

In the second connecting ribs 31 arranged in parallel in the length direction D2, a step (boundary) is formed between the first connecting region 31A and the second connecting region 31B at the position where the second connecting rib 31 intersects with the reinforcing rib 27. In contrast, in the second connecting ribs 31 arranged in parallel along the width direction D3, a step (boundary) is formed between the first connecting region 31A and the second connecting region 31B on the inner wall 25 side of the position where the second connecting rib 31 intersects with the reinforcing rib 27.

Furthermore, the second connecting ribs 31 arranged in parallel along the width direction D3 have their first connecting regions 31A connected to a part of the lattice rib 23 on the inside of the inner wall 25 via the inner wall 25. Also, the second connecting ribs 31 located at the four corners of the central girder wall 5 have their first connecting regions 31A connected to the reinforcing ribs 27 via the inner wall 25.

As shown in FIG. 6, when the pallet bodies 15A and 15B are integrated, the half of the central girder wall 5 on the pallet body 15A side and the half of the central girder wall 5 on the pallet body 15B side are integrated to form the central girder wall 5 of the resin pallet 1.

In the central girder wall 5 of the resin pallet 1, the annular wall 21 on the pallet body 15A side is connected to the annular wall 21 on the pallet body 15B side, and the inner wall 25 on the pallet body 15A side is connected to the inner wall 25 on the pallet body 15B side. As a result, in the central girder wall 5 of the resin pallet 1, the annular wall 21 and the inner wall 25 connect the deck surface 3 on the pallet body 15A side to the deck surface 3 on the pallet body 15B side.

In addition, in the central girder wall 5 of the resin pallet 1, a part of the lattice rib 23 on the inside of the inner wall 25 on the pallet body 15A side is connected to a part of the lattice rib 23 on the inside of the inner wall 25 on the pallet body 15B side, and the first connecting rib 29 on the pallet body 15A side is connected to the first connecting rib 29 on the pallet body 15B side. As a result, in the central girder wall 5 of the resin pallet 1, the deck surface 3 on the pallet body 15A side is connected to the deck surface 3 on the pallet body 15B side by the part of the lattice rib 23 on the inside of the inner wall 25 and the first connecting rib 29.

Furthermore, in the central girder wall 5 of the resin pallet 1, the second connection region 31B of the second connecting rib 31 on the pallet body 15A side is connected to the second connection region 31B of the second connecting rib 31 on the pallet body 15B side. As a result, in the central girder wall 5 of the resin pallet 1, the deck surface 3 on the pallet body 15A side and the deck surface 3 on the pallet body 15B side are also connected by the second connection region 31B of the second connecting rib 31.

In contrast, in the central girder wall 5 of the resin pallet 1, the first connection region 31A of the second connecting rib 31 on the pallet body 15A side and the first connection region 31A of the second connecting rib 31 on the pallet body 15B side are separated while facing each other in the vertical direction D1. Therefore, the first connection region 31A of the second connecting rib 31 on the pallet body 15A side is connected to the deck surface 3 on the pallet body 15A side, but not to the deck surface 3 on the pallet body 15B side. On the other hand, the first connection region 31A of the second connecting rib 31 on the pallet body 15B side is not connected to the deck surface 3 on the pallet body 15A side, but is connected to the deck surface 3 on the pallet body 15B side.

(3) Overview of the First Intermediate Girder Wall As shown in Fig. 7, the half body of the first intermediate girder wall 9 has the same structure as the half body of the central girder wall 5 described above, except for the differences described below. Therefore, in Fig. 7, the parts common to the half body of the central girder wall 5 are given the same reference numerals, and detailed explanations are omitted.

In a plan view, the annular wall 21 is an approximately rectangular ring with the width direction D3 longer than the length direction D2. In the second connecting ribs 31 arranged in parallel in the width direction D3 on the outer edge side of the deck surface 3, a step (boundary) is formed between the first connecting region 31A and the second connecting region 31B on the annular wall 21 side of the position where the second connecting rib 31 and the reinforcing rib 27 intersect.

(4) Overview of the Second Intermediate Girder Wall As shown in Fig. 8, the half body of the second intermediate girder wall 11 has the same structure as the half body of the central girder wall 5 described above, except for the differences described below. Therefore, in Fig. 8, the parts common to the half body of the central girder wall 5 are given the same reference numerals, and detailed explanations are omitted.

The inner wall 25 is disposed inside the annular wall 21 at a predetermined distance from the three sides of the annular wall 21 located inside the outer edge of the deck surface 3, along the three sides of the annular wall 21, forming a U-shape in plan view. Therefore, both ends 25E, 25E of the inner wall 25 are connected to one side of the annular wall 21 located on the outer edge side of the deck surface 3. Therefore, the reinforcing rib 27 is disposed in the center between the annular wall 21 and the inner wall 25 along the annular wall 21 and the inner wall 25, forming a U-shape in plan view.

In addition, among the lattice ribs 23 surrounded by the annular wall 21 and the inner wall 25 located on the outer edge side of the deck surface 3, the rib that is connected to the first connecting region 31A of the second connecting rib 31 parallel to the width direction D3 via the inner wall 25 has a wall height (distance in the vertical direction D1) on the inner wall 25 side that is the same as the wall height (distance in the vertical direction D1) of the first connecting region 31A of the second connecting rib 31, and a wall height (distance in the vertical direction D1) on the annular wall 21 side that is the same as the wall height (distance in the vertical direction D1) of the annular wall 21, forming a step.

(5) Overview of Corner Beam Wall As shown in Fig. 9, the half of the corner beam wall 7 has the same structure as the half of the central beam wall 5 described above, except for the differences described below. Therefore, in Fig. 9, the parts common to the half of the central beam wall 5 are given the same reference numerals, and detailed explanations are omitted.

The inner wall 25 is disposed inside the annular wall 21 at a predetermined distance from two sides of the annular wall 21 located inward from the outer edge of the deck surface 3, along the two sides of the annular wall 21, forming an L-shape in plan view. Therefore, both ends 25E, 25E of the inner wall 25 are connected to two sides of the annular wall 21 located on the outer edge side of the deck surface 3. Therefore, the reinforcing rib 27 is disposed in the center between the annular wall 21 and the inner wall 25 along the annular wall 21 and the inner wall 25, forming an L-shape in plan view.

In addition, among the lattice ribs 23 surrounded by the annular wall 21 and the inner wall 25 located on the outer edge side of the deck surface 3, the rib that is connected to the first connecting region 31A of the second connecting rib 31 parallel to the width direction D3 via the inner wall 25 has a wall height (distance in the vertical direction D1) on the inner wall 25 side that is the same as the wall height (distance in the vertical direction D1) of the first connecting region 31A of the second connecting rib 31, and a wall height (distance in the vertical direction D1) on the annular wall 21 side that is the same as the wall height (distance in the vertical direction D1) of the annular wall 21, forming a step.

Furthermore, among the lattice ribs 23 surrounded by the annular wall 21 and the inner wall 25 located on the outer edge side of the deck surface 3, the rib that is connected to the first connecting region 31A of the second connecting rib 31 parallel to the longitudinal direction D2 via the inner wall 25 has a wall height (distance in the vertical direction D1) on the inner wall 25 side that is the same as the wall height (distance in the vertical direction D1) of the first connecting region 31A of the second connecting rib 31, and a wall height (distance in the vertical direction D1) on the annular wall 21 side that is the same as the wall height (distance in the vertical direction D1) of the annular wall 21, forming a step.

(6) Summary As described above in detail, in the resin pallet 1 of this embodiment, the inner wall 25 and the reinforcing rib 27 extend parallel to the central girder wall 5 (annular wall 21) inside the central girder wall 5 (annular wall 21). This reinforces the periphery of the central girder wall 5 (annular wall 21) connecting the upper and lower deck surfaces 3, 3, and increases the bending rigidity of the central girder wall 5 against the load of the cargo. In this way, the resin pallet 1 of this embodiment improves the effect of suppressing the deflection of the upper and lower deck surfaces 3, 3. This is also true for the corner girder wall 7, the first intermediate girder wall 9, and the second intermediate girder wall 11.

However, in the second intermediate girder wall 11, the inner wall 25 and the reinforcing rib 27 extend parallel to the three sides of the second intermediate girder wall 11 (annular wall 21) located inside the outer edges of the upper and lower deck surfaces 3, 3, forming a U-shape in plan view. As a result, the resin pallet 1 of this embodiment reinforces the periphery of the second intermediate girder wall 11 (annular wall 21) located inside the outer edges of the upper and lower deck surfaces 3, 3 among the periphery of the second intermediate girder wall 11 (annular wall 21) connecting the upper and lower deck surfaces 3, 3, thereby increasing the bending rigidity of the second intermediate girder wall 11 against the load of the cargo. Therefore, the deflection of the upper and lower deck surfaces 3, 3 is suppressed by the efficient structure of the second intermediate girder wall 11.

In addition, the corner wall 7 has an L-shape in plan view, with the inner wall 25 and reinforcing rib 27 extending parallel to the two sides of the corner wall 7 (annular wall 21) inside the two sides of the corner wall 7 (annular wall 21) located inside the outer edges of the upper and lower deck surfaces 3, 3. As a result, the resin pallet 1 of this embodiment reinforces the periphery of the corner wall 7 (annular wall 21) that connects the upper and lower deck surfaces 3, 3, located inside the outer edges of the upper and lower deck surfaces 3, 3, thereby increasing the bending rigidity of the corner wall 7 against the load of the cargo. Therefore, the deflection of the upper and lower deck surfaces 3, 3 is suppressed by the efficient structure of the corner wall 7.

However, in the second intermediate girder wall 11 and the corner girder wall 7, the inner wall 25 and the reinforcing rib 27 may form a rectangular ring shape in a plan view inside the second intermediate girder wall 11 (annular wall 21) and the corner girder wall 7 (annular wall 21), similar to the first intermediate girder wall 9.

In the resin pallet 1 of this embodiment, the central girder wall 5 (annular wall 21) and the inner wall 25 are connected by the first connecting rib 29 and the second connecting rib 31, so that the bending rigidity of the central girder wall 5 against the load of the cargo is further increased. This is also true for the corner girder walls 7, the first intermediate girder wall 9, and the second intermediate girder wall 11.

In the resin pallet 1 of this embodiment, the central girder wall 5 is provided with a first connecting region 31A that has a lower wall height (distance in the vertical direction D1) than the central girder wall 5 (annular wall 21) and the inner wall 25 and connects to one of the upper and lower deck surfaces 3, 3, and a second connecting region 31B that connects to both the upper and lower deck surfaces 3, 3, thereby achieving a balance between suppressing weight increase and improving the bending rigidity of the central girder wall 5 against the load of the cargo. The same is true for the corner girder walls 7, the first intermediate girder wall 9, and the second intermediate girder wall 11.

Incidentally, in this embodiment, the upper and lower deck surfaces 3 are an example of "upper and lower deck surfaces". The central girder wall 5 is an example of a "girder wall". The corner girder wall 7 is an example of a "girder wall". The first intermediate girder wall 9 is an example of a "girder wall". The second intermediate girder wall 11 is an example of a "girder wall". The first connecting rib 29 is an example of a "connecting rib". The second connecting rib 31 is an example of a "connecting rib".

(7) Modifications The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention.
For example, in the central girder wall 5, the corner girder wall 7, the first intermediate girder wall 9, and the second intermediate girder wall 11, the wall height (distance in the vertical direction D1) of the reinforcing rib 27 may be made the same as the wall height (distance in the vertical direction D1) of the annular wall 21 and the inner wall 25, so that the reinforcing rib 27 is connected to the deck surface 3 on the pallet body 15A side and the deck surface 3 on the pallet body 15B side. In such a case, although the present embodiment is lighter, the bending rigidity of the central girder wall 5, the corner girder wall 7, the first intermediate girder wall 9, and the second intermediate girder wall 11 against the load of the cargo is higher than that of the present embodiment.

In addition, in the central girder wall 5, corner girder wall 7, first intermediate girder wall 9, and second intermediate girder wall 11, the wall height (distance in the vertical direction D1) of the first connecting rib 29 and the wall height (distance in the vertical direction D1) of the second connecting region 31B of the second connecting rib 31 may be lower than the wall height (distance in the vertical direction D1) of the annular wall 21 and the inner wall 25. In such a case, the weight is lighter than in this embodiment, and since the first connecting rib 29 and the second connecting rib 31 are connected to either the deck surface 3 on the pallet body 15A side or the deck surface 3 on the pallet body 15B side, the bending rigidity of the central girder wall 5, corner girder wall 7, first intermediate girder wall 9, and second intermediate girder wall 11 against the load of the cargo is increased compared to the conventional technology.

In addition, in the central girder wall 5, the corner girder wall 7, the first intermediate girder wall 9, and the second intermediate girder wall 11, the wall height (distance in the vertical direction D1) of the first connection region 31A of the second connection rib 31 may be made the same as the wall height (distance in the vertical direction D1) of the annular wall 21 and the inner wall 25, so that the first connection region 31A of the second connection rib 31 is connected to the deck surface 3 on the pallet body 15A side and the deck surface 3 on the pallet body 15B side. As a result, the first connection rib 29 and the second connection rib 31 are connected to the deck surface 3 on the pallet body 15A side and the deck surface 3 on the pallet body 15B side, so that the bending rigidity of the central girder wall 5, the corner girder wall 7, the first intermediate girder wall 9, and the second intermediate girder wall 11 against the load of the cargo is increased more than in this embodiment.
