Description of the Related Art Conventionally, plastic pallets for storing and transporting luggage have been widely used because of their excellent corrosion resistance and contamination resistance. This kind of pallet connects the upper deck board and the lower deck board with the pillars of the hollow structure arranged at both ends and the intermediate part, and the space surrounded by the pillars and the upper and lower deck boards is used for the fork of the forklift. It has a fork insertion slot. FIG. 6 is a perspective view showing an example of a conventional four-sided pallet. The four-sided pallet 1 is provided with a pillar 7 at the four corners of the upper deck board 3 and the lower deck board 5 and an intermediate pillar 9 in the middle thereof. And

However, a hand lift (a small manual forklift) or a pallet truck is used. In order to enable the use of the lower deck board 5, a relatively large opening 11 is provided in a portion surrounded by each of the pillars, and the lower deck board 5 is provided so as to connect the pillars vertically and horizontally.

供するものである。In such a pallet having a relatively large opening 11 in a portion surrounded by each of the columns, the height of the lower deck board is increased in order to facilitate insertion of a hand lift. It is desirable to be as low as possible. If the height of the lower deck board is reduced, the insertion of the hand lift becomes easy, and the carrying work by the hand lift can be efficiently performed. However, simply lowering the height of the lower deck board will reduce the strength of the lower deck board and, consequently, the strength of the entire pallet. Accordingly, the present invention provides a plastic pallet that can withstand the use of a hand lift.

る。BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention. 1 is a front view of the pallet, FIG. 2 is a bottom view of the upper half, and a plan view of the lower half. FIG. 3 is a cross-sectional view taken along the line AA of FIG. 1 and FIG. 4 is a cross-sectional view taken along the line B-B of FIG. 5 is a cross-sectional view taken along the line CC of FIG. 2. The pallet 20 is formed by connecting the upper deck board 21 and the lower deck board 23 with four corner pillars 25 and an intermediate pillar 27 provided therebetween, and the upper and lower deck boards 21 and 23 and the pillar 25 and the pillar 27. This is a four-sided pallet in which the gap surrounded by the fork insertion port 29 is defined.
The pallet 20 includes an upper part having an upper deck board that is divided and formed in a horizontal direction at a substantially central portion of each pillar in advance,
A lower part having a lower deck board is butted and welded to a support part at a support part, and the support part has a hollow structure.

た。The upper deck board 21 includes a top plate 30 and reinforcing ribs 31 provided vertically and horizontally on the lower surface of the top plate 30. The lower deck board 23 is provided in a beam shape so as to connect the columns, and a portion surrounded by the columns has a large opening 33. Thus, opening 3
The provision of 3 makes it possible to use a hand lift. According to the present invention, in order to facilitate insertion of the hand lift, the lower deck board 23a at the front is made lower in height than the height of the lower deck board 23b at the side, and the lower deck board 23a has a structure having sufficient strength. The height of the fork insertion port 29 above the board 23a is increased by the amount by which the height of the lower deck board 23a is reduced.

Can be reduced, and the height of the fork insertion port can be increased by the lower deck board 23a. Therefore, the insertion of the hand lift is facilitated, and the strength of the lower deck board 23a and thus the strength of the entire pallet can be increased. The height of the lower deck board 23a is
Or less than half the height of
