Further, in the tubular portion 44 of the central girder 43, a reinforcing rib 45 is formed by ribs along one side of the upper surface deck portion 2 and ribs connected orthogonally to the ribs in a plan view. Hereinafter, the reinforcing rib 45 possessed by the central girder 43 is particularly referred to as the reinforcing rib 6, and is distinguished from the reinforcing rib 45 possessed by the corner girder 41 and the intermediate girder 42. The tubular portion 5 and the reinforcing rib 6 will be described later.

When the lower portion 31 of the girder of the lower deck portion 3 and the lower surface of the lower rail portion 32 are placed on a horizontal plane, the upper surfaces of the girder upper portion 21, the upper rail portion 22, and the upper rail portion 23 of the upper deck portion 2 are horizontally identical. Located on a flat surface. That is, the thickness of the pallet 1 (that is, the vertical length between the upper surface and the lower surface) is formed to be constant.

As shown in FIG. 1, the pallet 1 has a fork insertion slot 10. The fork insertion port 10 is formed between the upper surface deck portion 2 and the lower surface deck portion 3 and between the corner girder 41 and the intermediate girder 42. Specifically, as shown in FIG. 4, the fork insertion port 10 has the upper end rail portion 221 on the upper side, the lower end rail portion 321 on the lower side, and the corner girder 41 and the intermediate girder 42 on the side. It is the part surrounded by these. The fork insertion openings 10 correspond to each pair of the upper end rail portion 221 and the lower end rail portion 321, and two fork insertion openings 10 are provided on each of the four sides of the pallet 1, for a total of eight forks.

The fork insertion port 10 is open toward the side, and the fork 9 of the forklift (see the broken line in FIG. 4) is inserted. The fork 9 is inserted from the fork insertion port 10 formed on one side of the pallet 1, and the tip of the fork 9 protrudes slightly from the fork insertion port 10 formed on the side facing one side of the pallet 1, but the fork 9 is not necessarily fork 9. The tip of the pallet does not have to come out from the fork insertion slot 10. The series of spaces in which the fork 9 can be inserted becomes the fork insertion space 11. That is, the fork insertion space 11 is between the upper end rail portion 221 and the lower end rail portion 321 (fork insertion port 10), between the upper rail portion 23 and the lower rail portion 33, and the inner upper rail portion 222. A series of series reaching between the inner and lower rails 322, between the upper rails 23 and the lower rails 33, and between the end upper rails 221 and the end lower rails 321 (fork insertion port 10). It is composed of space. Two fork insertion spaces 11 are arranged side by side on one side of the pallet 1 and a side facing the pallet 1, and two fork insertion spaces 11 are arranged side by side on a side adjacent to one side of the pallet 1 and a side facing the side, for a total of four forks. It is provided so as to form a well shape in a plan view. The pallet 1 is a so-called four-sided pallet.

The upper deck portion 2 of the pallet 1 has a girder upper portion 21, an upper rail portion 22, and an upper rail inter-section portion 23, and the upper deck portion 2 is not formed with a large opening and is loaded on the upper surface of the upper deck portion 2. Things are placed. Further, in the present embodiment, the lower surface deck portion 3 has a girder lower portion 31, a lower rail portion 32, and a lower rail inter-section portion 33, and the lower surface deck portion 3 is not formed with a large opening. Therefore, the load is placed on the upper surface of the lower surface deck portion 3 with the lower surface deck portion 3 on the upper side and the upper surface deck portion 2 on the lower side. That is, the pallet 1 of the present embodiment is a pallet 1 for double-sided use. The pallet 1 may be a single-sided pallet 1.

As shown in FIGS. 6A and 7, the tubular portion 5 has a rectangular shape in a plan view (particularly, a square shape in the present embodiment). In the present embodiment, the central girder upper portion 213 integrally continuous with the upper side of the central girder 43 and the central girder lower portion 313 integrally continuous with the lower side of the central girder 43 also have the same tubular portion and the same tubular portion as the tubular portion 5 and the reinforcing rib 6. It has a reinforcing rib. In other words, the tubular portion 5 and the reinforcing rib 6 are formed not only over the central girder 43 but also over the central girder upper portion 213 and the central girder lower portion 313. The tubular portion 5 and the reinforcing rib 6 do not have to be formed from the central girder 43 to the central girder upper part 213 and the central girder lower part 313, and may be formed at least in the central girder 43.

As shown in FIGS. 6A, 8 and 9, the end of the reinforcing rib 6 is connected to the tubular portion 5. As shown in FIGS. 8 and 9, the vertical intermediate portion 61 of the reinforcing rib 6 is formed only up to a portion horizontally separated from the tubular portion 5 by a predetermined length, and the upper end portion of the reinforcing rib 6 is formed. The 62 and the lower end portion 63 are formed up to a portion separated from the tubular portion 5 in the horizontal direction by a predetermined length (the length of the intermediate portion 61) or more.

A top plate portion 64 is formed between the upper end portions 62 of the adjacent reinforcing ribs 6. As shown in FIG. 7, as the top plate portion 64, four rectangular top plate portions 641 formed at the corners of the rectangular region surrounded by the tubular portion 5 in a plan view, and an L-shaped top plate portion 641. Four top plate portions 642 having a shape are formed. However, the top plate portion 641 is formed not between the upper end portions 62 of the adjacent reinforcing ribs 6 but between the upper end portions 62 of the reinforcing ribs 6 and the upper end portions of the tubular portion 5. The shape of the top plate portion 64 is not limited. Further, although the top plate portion 64 is formed in the present embodiment, the top plate portion 64 may not be particularly formed.

A bottom plate portion 65 is formed between the lower end portions 63 of the adjacent reinforcing ribs 6. As shown in FIGS. 6A and 7, as the bottom plate portion 65, four L-shaped bottom plate portions 651 and one cross-shaped bottom plate portion 652 are formed in a plan view. The shape of the bottom plate portion 65 is not limited. Further, although the bottom plate portion 65 is formed in the present embodiment, the bottom plate portion 65 may not be particularly formed.

As shown in FIG. 7, the top plate portion 64 and the bottom plate portion 65 are formed at positions shifted from each other in a plan view. As shown in FIG. 8, the bottom plate portion 65 is located below the upper mold (see the broken line 81 in FIG. 8) of the mold for molding the pallet 1 when the pallet 1 is molded. Further, as shown in FIG. 9, the top plate portion 64 is located above the lower mold (see the broken line 82 in FIG. 9) of the mold for molding the pallet 1 when the pallet 1 is molded.

The central girder 43 further has a partition rib 7. The partition rib 7 is connected to the reinforcing rib 6 (particularly, the reinforcing rib 6 connected to the upper rail portion 22 or the lower rail portion 32) and is not connected to the tubular portion 5. The partition rib 7 roughly partitions the space surrounded by the tubular portion 5. The space surrounded by the tubular portion 5 does not have to be completely divided by the partition rib 7. In the present embodiment, as shown in FIG. 6A, the partition rib 7 is formed in an X shape in a plan view.

As described above, since the partition rib 7 is not connected to the tubular portion 5, the length of the partition rib 7 is longer than that in the case where the end portion of the partition rib 7 extends to the tubular portion 5 and is connected to the tubular portion 5. Can be short. As a result, the weight of the entire pallet 1 can be suppressed by the amount that the length of the partition rib 7 is shortened. At this time, the bending strength of the pallet 1 may be slightly lowered, but the bending strength of the pallet 1 is not so lowered as a whole, and there is no problem in practical use.

Further, as shown in FIG. 6B, the end portion of the partition rib 7 in the horizontal direction in the longitudinal direction is a protruding end portion 71 protruding from the reinforcing rib 6. A protruding end portion 71 protrudes from a corner of a space 50 having a rectangular shape in a plan view, which is located below the top plate portion 641 (see FIGS. 7 and 9) and is surrounded by a tubular portion 5 and a reinforcing rib 6. There is. The space 50 is formed by the lower mold 82 as shown in FIG. The lower mold 82 is pulled out downward with respect to the pallet 1. At this time, the corner portion of the lower mold 82 is formed on the wall surface of the corner portion (corner portion of the space 50) formed by the tubular portion 5 and the reinforcing rib 6. When pressed, the lower mold 82 may be difficult to come off from the pallet 1 due to friction. In the present embodiment, since the protruding end portion 71 protrudes from the corner formed by the tubular portion 5 and the reinforcing rib 6 and the corner portion of the space 50 is not formed, the corner portion of the lower mold 82 is formed by the tubular portion 5 and the reinforcing rib. It is difficult to be caught by the wall surface of the corner formed by 6 and the lower mold 82 is prevented from being easily pulled out from the pallet 1, and the durability of the lower mold 82 is improved. In the present embodiment, the lower mold 82 corresponds to the corner formed by the tubular portion 5 and the reinforcing rib 6, but the upper mold 81 may correspond to the corner portion.

Further, as shown in FIG. 7, the upper end portion of the partition rib 7 is connected to the top plate portion 64. By connecting the upper end of the partition rib 7 to the top plate 64, the upper end of the partition rib 7 does not come into contact with the load placed on the upper surface of the pallet 1, and the upper surface of the top plate 64 comes into contact with the load. Therefore, it is possible to prevent the load from being marked with the edge of the partition rib 7.

Further, as shown in FIG. 8, the cross section 72 of the partition rib 7 located above the bottom plate portion 65 (the cross section orthogonal to the longitudinal direction of the partition rib 7 in the horizontal direction) becomes thinner as it goes upward. It has a taper. This makes it easier for the upper mold 81 to come out of the pallet 1 upward.

Further, as shown in FIG. 9, the cross section 73 of the partition rib 7 located below the top plate portion 64 (the cross section orthogonal to the longitudinal direction of the partition rib 7 in the horizontal direction) becomes thinner as it goes downward. Has a good taper. This makes it easier for the lower mold 82 to come off the pallet 1 downward.

In the present embodiment, the thickness of the thinnest portion of the partition rib 7 is formed so that the thickness of the ribs other than the partition rib 7 (including the reinforcing rib 6) is equal to each other. The thickness of the thinnest portion of the partition rib 7 may be formed to be thicker than the thickness of the ribs (including the reinforcing rib 6) other than the partition rib 7.

Next, the pallet 1 according to the second embodiment will be described with reference to FIG. The pallet 1 of the second embodiment is almost the same as the pallet 1 of the first embodiment. Therefore, the description that overlaps with the first embodiment will be omitted.

In the first embodiment, the partition rib 7 is formed in an X shape in a plan view. On the other hand, in the second embodiment, the partition rib 7 is formed in a square shape in a plan view. The reinforcing rib 6 is the same as that of the first embodiment. As described above, even in the partition rib 7 formed in a square shape in a plan view, since the partition rib 7 is not connected to the tubular portion 5, the length of the partition rib 7 is shortened, and the weight of the entire pallet 1 is increased. It can be suppressed.

Further, as a further example of the partition rib 7, the central portion of the partition rib 7 which is formed in an X-shape in a substantially plan view and where the X-shapes intersect may be formed in a square shape. That is, the partition rib 7 may have a shape in which the central portion is formed in a square shape and the ribs extend radially from each corner portion. The reinforcing rib 6 is the same as that of the first embodiment.

Further, as a further example of the partition ribs 7, a plurality of partition ribs 7 may be arranged side by side at intervals so as to extend in the same direction.

Further, as a further example of the partition rib 7, the partition rib 7 is substantially the same as the first embodiment, but the reinforcing rib 6 is different from the first embodiment. That is, the bottom plate portion 65 of the reinforcing rib 6 is formed with only four L-shaped bottom plate portions 651, and one cross-shaped bottom plate portion 652 is not formed. In this case, the bending strength of the pallet 1 is improved by connecting the end portions of the partition ribs 7 to the bottom plate portion 651.

As is clear from the above-described first embodiment to the second embodiment and the modified examples thereof, the pallet (1) of the first embodiment includes a top deck portion (2) formed in a rectangular shape in a plan view. It includes a lower deck portion (3) formed in a rectangular shape in a plan view, a corner girder (41), an intermediate girder (42), and a central girder (43), and is formed in a rectangular shape in a plan view. The corner girder (41) connects each corner of the upper deck portion (2) and each corner of the lower deck portion (3), respectively. The intermediate girder (42) connects the intermediate portion of each side of the upper deck portion (2) and the intermediate portion of each side of the lower deck portion (3), respectively. The central girder (43) connects the central portion of the upper deck portion (2) and the central portion of the lower deck portion (3), respectively. The pallet (1) has a fork insertion port (10) formed between the upper deck portion (2) and the lower deck portion (3) and between the corner girder (41) and the intermediate girder (42). Will be done. The central girder (43) has a tubular portion (5) extending in the vertical direction, a reinforcing rib (6) whose end is connected to the tubular portion (5), and a tubular portion (6) connected to the reinforcing rib (6). It has a partition rib (7) that is not connected to 5).

According to the first aspect, the length of the partition rib (7) is longer than that in the case where the end portion of the partition rib (7) extends to the tubular portion (5) and is connected to the tubular portion (5). It can be short. As a result, the length of the partition rib (7) is shortened, the weight of the entire pallet (1) is suppressed, and the bending strength of the pallet 1 is not significantly reduced.

The second aspect can be realized in combination with the first aspect. In the second aspect, the partition rib (7) is formed in an X shape in a plan view.
