。Synthetic resin shaft pallets usually have a structure in which the two boards that make up the deck board are joined at both ends and in the middle with mutually parallel girders, and compared to conventional wooden or metal pallets, they are Due to the nature of the synthetic resin, it is lightweight and has excellent chemical resistance, moisture resistance, etc. However, if the deck board has low bending rigidity, the deck board is reinforced by providing a lip or the like. However, [7. In the case of a pallet with legs, called a skid type, whose top surface is a flat plate, the back side of the deck board (the embossed ribs are formed integrally with the supporting legs in the same mold), so the lip is interrupted at the supporting legs, and the load is In this case, the amount of deflection of the interrupted portion of the lip increases and deforms.
また、リプが一方向に設置さカているために剛性の方向

し使用に限定され四方差し使用は剛性バランス上適用で
きない。また、フォークにより支脚が破損され易く、こ

等という問題点があった。Furthermore, since the lip is installed in one direction, there is a directional difference in rigidity, and the insertion direction of the fork is limited to one direction, that is, it is limited to two-way insertion, and four-way insertion cannot be applied due to rigidity balance. In addition, the supporting legs are easily damaged by the forks, and in this case, they cannot be replaced, resulting in problems such as a short lifespan of the pallet.

Alternatively, the fork is inserted from direction B or the opposite direction. As shown in FIG. 2, the back surface of the deck board 1 is alternately formed with hollow lips 4 and groove portions 5 that continuously extend radially from the center to the outer edge, and nine supporting legs 2 each having a circular cross section are connected to the threaded portion 3. They are screwed together and arranged.

It may be a mating fit or a bolted connection, but preferably a threaded connection. Note that the shape of the support and the legs 2 is not limited to what is shown in the figure, and may be, for example, a cylinder, a truncated cone, a polygon, an ellipse, a digit, etc., and the material thereof may be plastic, wood, metal, etc. However, it is preferable to use plastics that can be used by blow molding or injection molding.In particular, in order to obtain a special structure in which the void 7 of the supporting leg 2 has a cushion filled with air or foamed polyurethane, blow molding is preferable. Plastic ones are preferred.

ボ゛−ドの剛性がさらに向上する。Furthermore, the pallet of the present invention can be joined via a reinforcing material 8 between the back surface of the deck board 1 and the supporting legs 2 [Fig. 9 (a)
), (b) ). The reinforcing material may be anything that is lightweight and highly rigid; for example, it may be made of wood including plywood, hard urethane foam, hard polyvinyl chloride, etc. It can be installed on the entire back surface or around the supporting legs, or it can be installed on the entire back surface or around the supporting legs, or It can be installed in a strip like this. The installation of this reinforcing material further improves the rigidity of the board.

Because it has a structure like this, it adds a large resistance to bending of the deck board when inserted on all four sides, increasing bending rigidity12, and not only prevents deformation due to load, but also prevents deformation due to load. It is lightweight and easy to manufacture, and is more economical than injection molding molds1.Also, since the supporting legs are screwed together or connected by fitting, the supporting legs can be easily removed if damaged by the fork, etc. Since they are replaceable, the life of the pallet as a whole is extended, and the supporting legs, which are molded in one mold, are interchangeable and economical.
