It is known (see, for example, Patent Document 1 and the like).

Japanese Unexamined Patent Publication No. 2014-162557

By the way, for example, as pillars, the corner pillars provided at the four corners of the pallet, the intermediate pillars provided at the intermediate portions of the pair of corner pillars arranged along each side of the pallet, and the central portion of the pallet. In the configuration in which the central pillar portion to be provided is provided (four-way pallet), there is no pillar portion extending over the entire area in the predetermined width direction of the pallet, and even if a reinforcing member is embedded in the pillar portion. There is a concern that the effect of suppressing the deformation of the pallet can hardly be obtained.

Further, a structure that suppresses deformation of the pallet when the pallet is lifted by a forklift is desired.

The present invention has been made to solve the above-exemplified problems and the like, and an object of the present invention is to provide a pallet that can be effectively reinforced by a reinforcing member.

Hereinafter, each means suitable for solving the above-mentioned objectives and the like will be described separately for each item. In addition, if necessary, the action and effect peculiar to the corresponding means will be added.

Means 1. A deck portion having a substantially rectangular shape in a plan view having a mounting surface on which articles can be placed,
In a pallet including a plurality of pillars protruding downward from the deck,
The pillar portion is intermediate between the corner pillar portions provided at the four corners of the deck portion and the pair of corner pillar portions arranged along the pair of first side side portions facing each other among the side side portions of the deck portion. The first intermediate pillar portion provided at the position and the side side portion of the deck portion are lined up along a pair of opposite second side side portions extending substantially orthogonal to the first side side portion. A second intermediate pillar portion provided at an intermediate position between the pair of the corner pillar portions and a central pillar portion provided at the central portion of the pallet are provided.
A fork insertion portion capable of inserting a fork of a transportation means provided with a fork between the corner pillar portion and the first intermediate pillar portion, and between the corner pillar portion and the second intermediate pillar portion. Provided,
A pallet characterized in that a reinforcing member is installed from the upper part of each of the first intermediate pillars to the upper part of each of the second intermediate pillars.

According to the means 1, the upper part of each first intermediate pillar portion provided at the intermediate position of each first side side portion of the deck portion and each second intermediate provided at the intermediate position of each second side side portion of the deck portion. Reinforcing members are provided over the upper part of the pillars, and the reinforcing members arranged in a substantially square frame shape as a whole can effectively increase the strength and rigidity of the pallet, particularly the deck between the pillars. .. Therefore, for example, in the case where the pallets are installed on a pair of opposing rails provided parallel to each other and separated from each other, the corner pillar portions provided along the pair of first side sides of the pallets. Further, even in a situation where the first intermediate pillar portion is supported by the rail but the second intermediate pillar portion and the central pillar portion in between are not supported, deformation of the pallet or the like can be reliably suppressed.

Further, two reinforcing members are hung above each of the pair of fork insertion portions provided on the first side side of the pallet, and two reinforcing members are provided on the second side of the pallet. Two reinforcing members are hung above each of the pair of fork insertion portions. Therefore, even if the fork of the transport means is inserted into the fork insertion portion from either the first side side portion side or the second side side portion side of the pallet and the pallet is lifted, the lower surface side of the deck portion is the fork. A reinforcing member extending in a direction intersecting the fork is provided at the portion pressed by the fork. Therefore, the deformation of the pallet when the pallet is lifted by the transport means can be suppressed more reliably.

Further, both ends of the reinforcing member are located above the pillars and are supported by the pillars. For this reason, for example, as compared with the case where the reinforcing member is installed only in the deck portion between the pillar portions, it is possible to prevent a situation in which the peripheral portion of the reinforcing member cannot withstand the force received from the reinforcing member and is deformed or the like. Can be done.

For example, when a reinforcing member is installed between the corner columns along each side side of the pallet, two reinforcing members can be hung above each fork insertion portion. There is a concern that the total length of the reinforcing member used for one pallet will be relatively long. In this case, the weight of the pallet may increase (for example, the amount of the load decreases due to the weight limit), and the manufacturing cost of the pallet may increase. In this regard, according to the present means 1, the total length of the reinforcing member used for one pallet can be shortened as much as possible while two reinforcing members are hung above each fork insertion portion. Can be deterred.

Further, for example, when a reinforcing member is installed between each corner pillar portion and the central pillar portion, one end of all the reinforcing members is supported by the central pillar portion, and even if one end of each reinforcing member is installed in the central pillar portion. Even if an area that can support the part can be secured, the load tends to concentrate on the central pillar part, which causes deformation and the like (when the central pillar part is deformed, for example, installation of a pallet). It causes deterioration of balance etc.). In this respect, according to the present means 1, it is possible to avoid a situation in which a force is applied to a specific column portion from four reinforcing members, and the above concern can be dispelled.

Further, for example, from the first intermediate column portion to the second intermediate column portion, two first reinforcing members are provided so as to be parallel to each other, and between the pair of the first reinforcing members, from the corner column to the center. When two second reinforcing members are provided so as to be parallel to the pair of first reinforcing members, that is, when all the reinforcing members extend in the same extending direction, the reinforcing members are extended. There is no reinforcing member extending in the direction orthogonal to the existing direction, and there is a concern that the pallet is likely to be deformed when bending stress is generated in the same direction. In this regard, according to the present means 1, since two reinforcing members extending in the directions intersecting each other are provided, the above concerns can be dispelled, and deformation of the pallet or the like can be prevented more reliably. be able to.

Means 2. A pallet formed by welding a lower component portion including a pillar portion, a lower portion of the deck portion, and an upper component portion including an upper portion of the deck portion.
The means 1 according to means 1, wherein a concave accommodating portion for accommodating the reinforcing member is provided on at least one of the upper surface side of the lower component portion and the lower surface side of the upper component portion. palette.

According to the means 2, the reinforcing member embedded in the pallet can be reliably positioned, and rattling or the like of the reinforcing member can be suppressed. In addition, since the reinforcing member can be installed and fastened at the desired position in the work process of welding the lower component and the upper component, workability can be improved, and productivity can be improved. ..

Means 3. A pallet formed by welding a lower component portion including a pillar portion, a lower portion of the deck portion, and an upper component portion including an upper portion of the deck portion.
It is provided with an accommodating portion for accommodating the reinforcing member.
The accommodating portion is provided on the upper surface side of the lower component portion and is provided on the lower accommodating recess for accommodating the lower portion of the reinforcing member and the upper accommodating portion provided on the lower surface side of the upper component portion and accommodating the upper portion of the reinforcing member. The pallet according to means 1, wherein the pallet is provided with a recess.

According to the means 3, basically the same action and effect as those of the above means 2 are exhibited. Further, since the accommodating portion is provided not only in one of the lower component and the upper component but also in both, the height of the pallet is suppressed while ensuring the height of the reinforcing member. (If either the lower accommodating recess or the upper accommodating recess is not provided, the vertical width of the deck portion is increased by that amount). Therefore, it is possible to improve the transportation / storage efficiency. Further, it is possible to improve the durability of the pallet when a stress is applied to the pallet so that the lower component portion and the upper component portion are displaced in the horizontal direction.

By the way, as shown in FIGS. 3 and 7, in the present embodiment, between the lower component 12 and the upper component 21, a metal (for example, iron, stainless steel, etc.) square tubular reinforcement is used. An accommodating portion 32 in which the member 31 is installed (buried) is provided. More specifically, as shown in FIGS. 4 and 5, on the upper surface side of the lower component portion 12, a substantially straight line extends from the upper portion of each first intermediate pillar portion 7 to the upper portion of each second intermediate pillar portion 9. A lower accommodating recess 33 extending in a shape and accommodating the lower portion of the reinforcing member 31 is provided. Each lower accommodating recess 33 includes a first corresponding portion 34 provided above the first intermediate pillar portion 7, a second corresponding portion 35 provided above the second intermediate pillar portion 9, and a first intermediate pillar portion 7. , It is formed between the second intermediate pillar portion 9 and the fork corresponding portion 36 provided above the fork insertion portion 11.

The width of the portion on the side of the second side portion 8 for accommodating the portion is wider than the width of the fork-corresponding portion 36. In addition, the bottom surface of the first corresponding portion 34 and the bottom surface of the second corresponding portion 35 are positioned at the same height as the bottom surface of the fork corresponding portion 36, that is, the upper surface of the lower plate portion 14 (see FIG. 9). ).

Further, as shown in FIG. 6, an upper accommodating recess 41 for accommodating the upper portion of the reinforcing member 31 is provided on the lower surface side of the upper component 21 at a position corresponding to the lower accommodating recess 33. The upper accommodating recess 41 is provided so as to remove the target portion of the upper deck reinforcing rib 23, and the lower surface of the upper plate portion 22 constitutes the bottom surface (top wall surface) of the upper accommodating recess 41. Further, the upper accommodating recess 41 does not have a portion where the lateral width is widened like the second corresponding portion 35 of the lower accommodating recess 33, and the lateral width is constant at any position in the extending direction. In addition, the upper accommodating recess 41 connects the ends of the upper deck reinforcing rib 23 forming the inner side surface of the upper accommodating recess 41, and is substantially parallel to the side surface of the reinforcing member 31 installed in the upper accommodating recess 41. It is provided with an upper side wall portion 42 extending so as to extend, and an upper facing wall portion 43 facing substantially parallel to both ends of the reinforcing member 31 installed in the upper accommodating recess 41.

Then, during the welding work between the lower component 12 and the upper component 21, for example, as shown in FIG. 3, the lower deck 13 of the lower component 12 is arranged facing upward, and the reinforcing members are respectively placed in the lower accommodating recesses 33. After the 31 is installed, as shown in FIG. 7, the upper component portion 21 is covered and the upper edge portion of the lower deck reinforcing rib 15 and the lower edge portion of the upper deck reinforcing rib 23 are welded together. As a result, the lower component 12 and the upper component 21 are integrated to form the pallet 1 of the present embodiment, and inside the pallet 1, the lower accommodating recess 33 and the upper accommodating recess 41 form the pallet 1. An accommodating portion 32 accommodating the reinforcing member 31 is formed. The reinforcing member 31 accommodated in the accommodating portion 32 is brought into substantially contact with the bottom surface of the upper accommodating recess 41, that is, the lower surface of the upper plate portion 22.

Further, as shown in FIG. 5 and the like, in the present embodiment, the reinforcing member 31 extends from the upper portion of one of the first intermediate pillar portions 7 to the upper portion of the other first intermediate pillar portion 7 of the pair of first intermediate pillar portions 7. The central accommodating portion 44 is provided by forming recesses on the upper surface side of the lower constituent portion 12 and the lower surface side of the upper constituent portion 21 so that the above can be installed. Then, as shown in FIG. 10, the reinforcing member 31 is installed not only in the accommodating portion 32 (lower accommodating recess 33) but also in the central accommodating portion 44 according to the required strength of the pallet 1, and the lower constituent portion 12 And the upper component 21 are integrated, so that not only the reinforcing member 31 extending from the upper part of the first intermediate column portion 7 to the upper part of the second intermediate column portion 9 but also one of the first intermediate column portions is integrated. A reinforcing member 31 extending from the upper part of the 7 to the upper part of the other first intermediate pillar portion 7 via the upper portion of the central pillar portion 10 is embedded in the pallet 1.

As described in detail above, according to the present embodiment, the upper portion of each first intermediate pillar portion 7 provided at the intermediate position of each first side side portion 6 of the deck portion 3 and each second side of the deck portion 3 A reinforcing member 31 is provided over the upper portion of each second intermediate pillar portion 9 provided at an intermediate position of the side portion 8, and the reinforcing member 31 arranged in a substantially square frame shape as a whole makes the pallet 1, particularly the pillar portion 4 The strength and rigidity of the deck portion 3 between them can be effectively increased. Therefore, for example, in the case where the pallets 1 are installed on a pair of opposing rails provided parallel to each other and separated from each other, the corners provided along the pair of first side side portions 6 of the pallets 1 Even in a situation where the pillar portion 5 and the first intermediate pillar portion 7 are supported by the rail, but the second intermediate pillar portion 9 and the central pillar portion 10 in between are not supported, the deformation of the pallet 1 is ensured. Can be deterred.

Further, two reinforcing members 31 are hung above each of the pair of fork insertion portions 11 provided on the first side side portion 6 side of the pallet 1, and the second side side portion of the pallet 1 is provided. Two reinforcing members 31 are hung above each of the pair of fork insertion portions 11 provided on the eight side. Therefore, even if the fork of the forklift or the hand lift is inserted into the fork insertion portion 11 from either the first side side portion 6 side or the second side side portion 8 side of the pallet 1, the pallet 1 is lifted. A reinforcing member 31 extending in a direction intersecting the fork is provided at a portion of the deck portion 3 where the lower surface side is pressed by the fork. Therefore, the deformation of the pallet 1 when the pallet 1 is lifted by a forklift or the like can be suppressed more reliably.

Further, both ends of the reinforcing member 31 are located above the pillars 4 (first intermediate pillars 7 and second intermediate pillars 9), and are supported by the pillars 4. Therefore, for example, as compared with the case where the reinforcing member 31 is installed only on the deck portion 3 between the pillar portions 4, the peripheral portion of the reinforcing member 31 cannot withstand the force received from the reinforcing member 31 and is deformed or the like. The situation can be prevented.

For example, when a reinforcing member is installed between the corner columns along each side side of the pallet, two reinforcing members can be hung above each fork insertion portion. There is a concern that the total length of the reinforcing member used for one pallet will be relatively long. In this case, the weight of the pallet may increase (for example, the amount of the load decreases due to the weight limit), and the manufacturing cost of the pallet may increase. In this regard, according to the present embodiment, the total length of the reinforcing member 31 used for one pallet 1 can be shortened as much as possible while two reinforcing members 31 are hung above each fork insertion portion 11. It can deter the above concerns.

Further, for example, when a reinforcing member is installed between each corner pillar portion and the central pillar portion, one end of all the reinforcing members is supported by the central pillar portion, and even if one end of each reinforcing member is installed in the central pillar portion. Even if an area that can support the part can be secured, the load tends to concentrate on the central pillar part, which causes deformation and the like (when the central pillar part is deformed, for example, installation of a pallet). It causes deterioration of balance etc.). In this respect, according to the present embodiment, it is possible to avoid a situation in which a force is applied to the specific column portion 4 from the four reinforcing members 31, and the above concern can be dispelled.

Further, for example, from the first intermediate column portion to the second intermediate column portion, two first reinforcing members are provided so as to be parallel to each other, and between the pair of the first reinforcing members, from the corner column to the center. When two second reinforcing members are provided so as to be parallel to the pair of first reinforcing members, that is, when all the reinforcing members extend in the same extending direction, the reinforcing members are extended. There is no reinforcing member extending in the direction orthogonal to the existing direction, and there is a concern that the pallet is likely to be deformed when bending stress is generated in the same direction. In this regard, according to the present embodiment, since two reinforcing members 31 extending in the direction intersecting (orthogonally) with each other are provided, the above concerns can be dispelled, and the pallet 1 can be deformed or the like. It can be prevented more reliably.

In addition, for example, two reinforcing members are arranged in an abbreviated shape from one second intermediate column portion to each first intermediate column portion, and the central column is parallel to each of the two reinforcing members. When two reinforcing members are arranged in an abbreviated shape from the portion to the corner pillar portion, the pillar portion and the reinforcing member of the deck portion are arranged from one first side side portion to the other first side side portion. There is a concern that the uncorresponding parts will be continuous and the parts will be easily deformed. In this regard, according to the present embodiment, the parts of the deck portion 3 that do not correspond to the pillar portion 4 and the reinforcing member 31 extend from one first side side portion 6 to the other first side side portion 6. Since it does not extend from one second side side portion 8 to the other second side side portion 8, the above concern can be dispelled, and deformation of the pallet 1 and the like can be prevented more reliably. be able to.

Further, the pallet 1 is provided on the upper surface side of the lower component portion 12 and is provided on the lower accommodating recess 33 for accommodating the lower portion of the reinforcing member 31, and is provided on the lower surface side of the upper component portion 21 to accommodate the upper portion of the reinforcing member 31. An accommodating portion 32 composed of an upper accommodating recess 41 is provided. Therefore, the reinforcing member 31 embedded in the pallet 1 can be reliably positioned, and rattling or the like of the reinforcing member 31 can be suppressed. Further, since the reinforcing member 31 can be installed and fastened at the desired position in the work process of welding the lower component portion 12 and the upper component portion 21, workability is improved, and productivity is improved. be able to. Further, since the accommodating portion 32 is provided not only in one of the lower constituent portion 12 and the upper constituent portion 21 but also in both, the pallet 1 is provided while ensuring the height of the reinforcing member 31. The height of the (deck portion 3) can be suppressed (when either the lower accommodating recess 33 or the upper accommodating recess 41 is not provided, the vertical width of the deck portion 3 is increased by that amount. ). Therefore, it is possible to improve the transportation / storage efficiency. In addition, it is possible to improve the durability of the pallet 1 when a stress is applied to the pallet 1 so that the lower component 12 and the upper component 21 are displaced in the horizontal direction.

It suffices that the strength and rigidity of the pallet 1 can be increased as compared with the configuration in which the lower deck reinforcing rib 15 and the upper deck reinforcing rib 23 are only extended. For example, the reinforcing member may be made of glass fiber, carbon fiber, or the like, or the reinforcing member may have an I-shaped cross section, a cylindrical cross section, a circular cross section (solid), a square cross section (solid), or the like. It may be configured. Further, for example, the reinforcing member may be composed of a synthetic resin made of a material having a strength higher than that of the lower component 12 or the like, or a synthetic resin having a shape having a shape of increasing strength. In addition, the reinforcing member can be formed in an abbreviated shape or a square ring shape.

(C) In the above embodiment, the degree of the gap between the reinforcing member 31 accommodated in the accommodating portion 32 and the accommodating portion 32 is not particularly limited, but it is desirable that the gap is as small as possible. In particular, in the vertical direction (thickness direction of the deck portion 3), the reinforcing member 31 accommodated in the accommodating portion 32 comes into contact with the bottom surface of the lower accommodating recess 33 (upper surface of the lower plate portion 14), and the upper accommodating recess 41 It is desirable that the bottom surface (the lower surface of the upper plate portion 22) is in contact with or close to the bottom surface.
