Plastic pallet

Claim 1

In an integrally formed plastic pallet including a quadrilateral level upper surface A, a quadrilateral level standing surface B and spacers which join said two surfaces; the improvement wherein said level upper surface A comprises, in alternation, a first group of ribs comprised of ribs (1) of inwardly facing U-shaped section, which are disposed with a prescribed interval therebetween, and a second group of ribs comprised of ribs (2) of inwardly facing U-shaped section, which are disposed with a prescribed interval therebetween and in at right angles to said first ribs (1); said level standing surface B comprises, in alternation, a first group of ribs comprised of ribs (1'') of inwardly facing U-shaped section, which are disposed with a prescribed interval therebetween, and a second group of ribs comprised of ribs (2'') of inwardly facing U-shaped section, which are disposed with a prescribed interval therebetween and in at right angles to said first ribs (1''); said spacers comprise four hollow spacers (3), (3), (3), (3) disposed at the corners of the pallet, form hollow spacers (4), (4), (5), (5) disposed at the side portions of the pallet, and one hollow spacer (6) disposed substantially in the center of the pallet, thereby forming as a consequence of the presence of said spacers two sets of cavities (7), (8) for receiving the insertion of the fork of a forklift between said level upper surface (A) and level standing surface (B); the first ribs (1) of said level upper surface (A) and the first ribs (1'') of said level standing surface (B), when viewed from a direction perpendicular to one of said surfaces (2) the pallet, being disposed parallely but not superposedly relative to each other; likewise the second ribs (2) of said upper level surface (A) and the second ribs (2'') of said level standing surface (B), when viewed from a direction perpendicular to one of said surfaces of the pallet, being disposed parallely but not superposedly relative to each other; said level standing surface B having openings at below the four hexahedral spaces (9) formed by the intersection of said cavities (7) and (8), said openings being flared such that their spread exceeds the crosssectional area of said hexahedral spaces.
