Abstract

A pallet made of synthetic resin and including four corner posts, intermediate posts therebetween, a center post, with hollow edge boards connecting the corner posts and the intermediate posts, and hollow deck boards connecting the intermediate posts and the center post. The pallet is formed from four identical complementary elements combined along two crossed division lines, each element provided with the above described hollow edge boards and hollow deck boards, each of which have flat walls provided at both ends thereof to form a closed hollow space therein. Reinforcing ribs are provided in the hollow space in each of the edge boards such that the reinforcing ribs extend parallel to the side surfaces of the pallet and are disposed such that the ribs meet with one another at right angles in the four corners of the pallet. The pallet is assembled by butt fusing the reinforcing ribs and upper and lower flat walls of the elements together.

Claims

1. A pallet made of a synthetic resin and comprising four corner posts, intermediate posts provided between said corner posts, a center post, hollow edge boards connecting said corner posts and said intermediate posts, hollow deck boards provided in a crossed manner to connect said intermediate posts and said center post together, and fork inserting openings provided at the four sides of said pallet, wherein four identical complementary pallet elements are combined together along two crossed division lines on said pallet, said elements being provided with edge boards and deck boards, with flat walls provided at both ends of each of said edge boards and deck boards so as to form a closed hollow space in each of said elements, and reinforcing ribs provided in the hollow space in each of said edge boards such that said reinforcing ribs are extended in parallel with the side surfaces of said pallet and disposed such that said reinforcing ribs meet with one another at right angles in the four corners of said pallet, said reinforcing ribs and said upper and lower flat walls in each of said pallet elements being butt fused together.

2. The pallet as claimed in claim 1, wherein said two crossed division lines intersect at the approximate center of the pallet.

3. The pallet as claimed in claims 1 or 2, wherein the pallet comprises four triangular sections produced by crossed division lines extending diagonally of the pallet.

4. The pallet as claimed in claim 3, wherein each of the reinforcing ribs of the deck boards of each sections cross the reinforcing ribs of the edge boards at a right angle.

5. The pallet as claimed in claims 1 or 2, wherein the pallet comprises four square sections produced by crossed division lines extending parallel to the side ends of the pallet.

6. The pallet as claimed in claim 5, wherein each reinforcing rib of the deck boards of each section is oriented perpendicularly to the crossed division plane.

7. The pallet as claimed in claim 5, wherein each reinforcing rib of the deck boards of each section is oriented in the same direction as the reinforcing rib of either one of the edge boards.
