BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin pallet. Specifically, the invention relates to a synthetic resin pallet that exhibits excellent durability against impacts during work.

2. Description of the Related Art Synthetic resin pallets have been used in various fields in recent years because of their excellent hygiene, moldability, and durability. A synthetic resin pallet consists of a deck part on which cargo is placed and leg members provided on the underside of the deck part. A space is formed between the leg members, and a fork such as a forklift can be inserted into this space to lift it. It is something to work on. The leg member is long along the side of the deck member, and the leg member is also provided parallel to the center of the pallet so that the fork can be inserted from both the front and rear sides, which is called a two-way type.

[0003]Furthermore, a type in which leg members are provided at the square portion of the lower surface of the deck portion, at the intermediate portions of the four sides, and at the center portion of the deck portion so that the fork can be inserted from the front, back, right and left is called a four-way insert type. Furthermore, the upper and lower deck parts are made into almost the same plate shape, so that they can be used even when turned over, making it possible to use both sides, and the lower deck part is made up of narrow plate-shaped bodies that connect leg members to each other, making it possible to carry cargo. There are also single-sided types that have only one deck part to be placed on.

SUMMARY OF THE INVENTION The present invention relates to an improved four-sided single-sided pallet. In the case of this four-way type single-sided pallet, leg members are provided at at least nine locations including the square portion, the intermediate portions of the four sides, and the center portion. Among these leg members, the leg members especially those provided at the square portions often come into contact with other objects and receive shock during work, and there is a high possibility that the forks etc. will come into contact with them when inserting the fork of a forklift. The strength of the square leg members has had a significant impact on the performance of the pallet, as a large stress is applied when the pallet is bent due to the load of the cargo.

[0005] In addition, in the case of a four-sided single-sided pallet, the lower deck part has a structure in which the leg members are connected by plate-shaped bodies, so large openings are formed in the area surrounded by the plate-shaped bodies. It will be done. This hole is hand-lifted (
It is used to protrude the wheels of a simple manual lift with wheels underneath, but depending on the structure of the plate-shaped body that connects the leg members, it may be difficult for the wheels of the hand lift to fit in.
There were times when it was difficult to get it out.

[0006]

[Means for Solving the Problems] As a result of various studies, the present inventors have developed a special internal structure of the leg members and the structure of the lower deck board provided in the square parts of a four-sided single-sided synthetic resin pallet. The inventors discovered that this structure allows for a synthetic resin pallet with excellent strength and ease of use, and have completed the present invention. The gist of the present invention is to provide an upper deck part for placing cargo, a square part on the lower surface of the upper deck part, a middle part of the four sides, and a leg member in the center part of the deck part, and the lower deck part, It is a four-way synthetic resin pallet with a structure in which adjacent leg members are connected by plate-shaped bodies, and the leg members provided in the squares of the upper deck part have a hollow structure, and the upper deck part A partition wall extending diagonally from the corner position toward the center of the upper deck portion, and two partition walls extending in mutually intersecting directions substantially along the insertion direction of the fork are provided, and the leg members are connected to each other. The synthetic resin pallet is characterized in that the side of the plate-shaped lower deck portion facing the fork insertion hole is sloped downward from the center toward both ends.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view of an example of a pallet according to the present invention, FIG. 2 is a cross-sectional view (quarter) of an example of a pallet according to the present invention, and FIG. 3 is a sectional view taken along line AA in FIG. In the figure, 1 is a synthetic resin pallet, 2 is the upper deck part, 3, 4, and 5 are leg members, and 6
indicates the lower deck part, and 7, 8, and 9 indicate the partition walls, respectively. The synthetic resin pallet 1 is made of synthetic resin such as polyethylene or polypropylene by injection molding or the like. Since the pallet 1 has many undercut structural parts, for example, upper and lower members horizontally divided into two from near the horizontal center of the leg members 3, 4, and 5 are formed by injection molding or the like, and these are welded. For example, the pallet 1 may be constructed by integrating the pallet 1 by means such as the above.

The pallet 1 of the present invention has a special structure in the structure of the square leg members 3, 3, . . . and the structure of the lower deck portion 6. The square leg members 3, 3, . . . have a hollow structure, and a partition wall 7 is provided inside thereof extending substantially diagonally from the corner position of the upper deck portion toward the center of the upper deck portion. This partition wall 7 significantly improves the strength of the corners against impact.

Further, inside the leg member 3, partition walls 8 and 9 are provided which extend in a direction substantially along the fork insertion direction and intersect with each other. The partition walls 8 and 9 exhibit good strength against contact with the fork when the fork is inserted. These partition walls 7, 8, and 9 usually have the same height as the leg member 3, and partition the inside of the leg member 3 into a partition wall shape. Although the partition wall 7 shown in FIG. 2 crosses the leg member 3 diagonally, it may have a structure in which it is provided halfway (near the center of the leg member), depending on the desired strength. Similarly, partition walls 8 and 9 are similar to partition wall 7.
It may be cut off at the front without reaching .

The lower deck portion 6 has adjacent leg members 3 and 4.
...It is composed of plate-like bodies that connect comrades. Further, as shown in FIG. 3, the side of this plate-shaped body facing the fork insertion hole is sloped so that its cross-sectional shape becomes lower from the center toward both ends. This structure allows the wheels of the hand lift to move in and out smoothly. The top may be slightly shifted as long as it is near the center of the plate.

[Effects of the Invention] The synthetic resin pallet of the present invention has a structure with excellent impact resistance, and also exhibits excellent handling effects in hand lifts and the like. Therefore, the pallet has excellent durability in practical terms.
