[Problems to be solved by the invention]
In the above-described conventional synthetic resin pallet, the thickness of the connecting member that intersects the fork insertion passage formed on one opposite side surface is reduced in order to make it easier for the wheels of the hand forklift to get over the connecting member. However, the operator inserts the hand forklift into the fork insertion passage of the thicker connecting member formed on the other opposite side surface, and the wheel of the hand forklift truck gets over the connecting member. In addition, the hand forklift is pulled out of the fork insertion passage where a considerable arm force and time are required or a thick connecting member is arranged, and the hand fork lift is inserted into the fork where a thin connecting member is arranged. There was a problem that it had to be reinserted into the passage.

【Example】
Examples of the present invention will be described below. However, the present invention is not limited to these examples as long as the gist of the present invention is not exceeded.
[0007]
1 is an upper deck configured in a lattice structure, corner girders 2 are arranged at the four corners of the upper deck 1, and intermediate girders 3 are arranged between the corner girders 2, Further, a central girder 4 is disposed at the center of the upper deck 1. The lower deck 5 includes a connecting member 5 a that connects the corner beam 2 and the intermediate beam 3, and a connecting member 5 b that connects the intermediate beam 3 and the central beam 4, and the corner beam of the lower deck 5. A substantially rectangular portion 6 surrounded by a connecting member 5a for connecting 2 and the intermediate girder 3 and a connecting member 5b for connecting the intermediate girder 3 and the central girder 4 is formed into a bottomed structure (hereinafter referred to as a bottomed structure). This portion is referred to as a bottomed portion 6). A fork insertion passage 7 is formed between the corner beam 2 and the intermediate beam 3 on each side of the synthetic resin pallet and between the intermediate beam 3 and the central beam 4. As described above, the upper deck 1 configured in a lattice structure functions as a luggage placing portion on which a luggage is placed, and the lower deck 5 on which no luggage is placed includes a corner beam 2, an intermediate beam 3, and the like. Are composed of eight connecting members 5a and four connecting members 5b for connecting the intermediate beam 3 and the central beam 4. The planar shape of the synthetic resin pallet having the above configuration is formed in a square shape. In other words, the lateral widths of the four side surfaces constituting the synthetic resin pallet are all formed to the same width.
[0008]
The width w1 of the intermediate beam 3 located on one side surface Pa side of the synthetic resin pallet is formed narrower than the gap d1 between the pair of forks f1 of the hand forklift F1. Further, the width w2 of the intermediate beam 3 located on the opposite side Pb side of the synthetic resin pallet is formed narrower than the gap d2 between the pair of forks f2 of the forklift truck F2, and the hand forklift F1. Is formed wider than the gap d1 between the pair of forks f1. Accordingly, the pair of forks f1 of the hand forklift F1 can be inserted into the fork insertion passage 7 located on the one side surface Pa side of the synthetic resin pallet, but the other side surface of the synthetic resin pallet is opposite. The pair of forks f2 of the forklift truck F2 can be inserted into the fork insertion passage 7 located on the Pb side, but the pair of forks f1 of the hand forklift F1 comes into contact with the intermediate beam 3 and the hand forklift F1 The pair of forks f1 is configured not to be inserted. In addition, it is comprised so that the fork f2 of the forklift truck F2 can also be inserted in the fork insertion channel | path 7 which can insert a pair of fork f1 of the hand forklift F1.
[0009]
The fork insertion passage 7 into which the pair of forks f1 of the hand forklift F cannot be inserted, that is, the side surface Pb on which the intermediate beam 3 having a width w2 wider than the gap d1 between the pair of forks f1 of the hand forklift F1 is disposed. Connecting member 5a for connecting the corner beam 2 and the intermediate beam 3 intersecting the pair of forks f2 of the forklift truck F2 inserted from the side fork insertion passage 7 and connecting member 5b for connecting the intermediate beam 3 and the central beam 4. The thickness t1 is approximately the same as the thickness t2 of the upper deck 1. For example, the thickness t1 of the connecting members 5a and 5b is 20 to 25 mm.
[0010]
Further, a connecting member 5a and an intermediate beam that connect the intermediate beam 3 and the corner beam 2 intersecting with the pair of forks f1 of the hand forklift F1 inserted through the fork insertion passage 7 through which the pair of forks f1 of the hand forklift F1 can be inserted. The thickness t3 of the connecting member 5b that connects 3 and the central girder 4 is formed to be thinner than the thickness t2 of the upper deck 1. With this configuration, the wheel disposed on the fork f1 of the hand forklift F1 can easily get over the connecting members 5a and 5b. Therefore, the fork f1 of the hand forklift F1 into the fork insertion passage 7 can be obtained. The workability of the insertion work is improved. In addition, thickness t3 of said connection member 5a, 5b is formed in 15 mm or less, Preferably, it forms in 10 mm-15 mm.
[0011]
As described above, the connecting member 5a that connects the corner beam 2 and the intermediate beam 3 intersecting with the pair of forks f1 of the hand forklift F1 inserted through the fork insertion passage 7 through which the pair of forks f1 of the hand forklift F1 can be inserted. The thickness t3 of the connecting member 5b that connects the intermediate beam 3 and the central beam 4 is formed to be thinner than the thickness t2 of the upper deck 1, and accordingly, the strength of the connecting members 5a and 5b having a small thickness t3 Although the rigidity is lowered, a pair of forklift trucks F2 inserted from the fork insertion passage 7 on the side Pb side where the intermediate beam 3 having a width w2 wider than the gap d1 between the pair of forks f1 of the hand forklift F1 is disposed. The thickness t1 of the connecting member 5a connecting the corner beam 2 and the intermediate beam 3 intersecting the fork f2 and the connecting member 5b connecting the intermediate beam 3 and the central beam 4 is as follows. Since the thickness t2 of the parts deck 1 is thicker substantially to the same extent, it is possible to suppress the reduction in strength and rigidity of the entire synthetic resin pallet. Further, the fork f2 of the forklift truck F2 having a small thickness is inserted into the fork insertion passage 7 on the side surface Pb side where the intermediate beam 3 having a width w2 wider than the gap d1 between the pair of forks f1 of the hand forklift F1 is disposed. Since it is only inserted, the thickness t1 of the connecting members 5a and 5b intersecting with the pair of forks f2 of the forklift truck F2 inserted from the fork insertion passage 7 on the side surface Pb side is greater than the thickness t2 of the upper deck 1. Therefore, the strength and rigidity of the synthetic resin pallet as a whole can be further prevented from decreasing.
[0012]
As described above, the width w1 of the intermediate beam 3 positioned on one side surface Pa side of the synthetic resin pallet is formed narrower than the gap d1 between the pair of forks f1 of the hand forklift F1, and is made of synthetic resin. The width w2 of the intermediate beam 3 positioned on the other opposite side surface Pb side of the pallet is formed wider than the gap d1 between the pair of forks f1 of the hand forklift F1, and between the pair of forks f2 of the forklift truck F2. Since it is formed narrower than the gap d2, it is possible to prevent erroneous work such as inserting the pair of forks f1 of the hand forklift F1 into the fork insertion passage 7 into which the pair of forks f2 of the forklift truck F2 is inserted.
[0013]
The width w1 of the intermediate beam 3 located on one side surface Pa side of the synthetic resin pallet is formed narrower than the gap d1 between the pair of forks f1 of the hand forklift F1. Since the width w2 of the intermediate beam 3 positioned on the opposite side surface Pb side is formed wider than the gap d1 between the pair of forks f1 of the hand forklift F1, colors or seals are pasted on the synthetic resin pallet, etc. Without taking any special measures, the operator can determine whether the intermediate beam 3 is wide or narrow so that it is positioned on the fork insertion passage 7 side for the hand forklift F1 or the forklift Whether the vehicle is located on the fork insertion passage 7 side for the vehicle F2 can be easily and quickly identified.
[0014]
