Abstract

A pallet for the movement of goods includes several individual parts connected to one another, including an upper section and a frame section. The upper section includes a plurality of openings, which are located in recesses formed in the underside of the upper section, which help the escape of heat through the pallet. The pallet may be formed from a fire retardant material and may be certified to comply with the Underwriters Laboratories, Inc. Standard 2335 “Fire Tests of Storage Pallets.” The pallet may include a transponder for locating the pallet.

Claims

1. A pallet for the movement of goods, comprising:

an upper deck forming a loading part with a loading surface;

a frame section generally corresponding to the size of the loading surface and, at least at its corners, has spacers which point to the upper deck and have a material-fit connection to the upper deck; and

wherein the upper deck includes an upper side forming said loading surface, an underside facing downwardly toward said frame section, the upper side of the upper deck having a planar surface with a plurality of transverse openings extending through the upper deck to provide air circulation through the pallet to allow for the release of heat and combustible gases in the case of a fire and to allow for water distribution through the pallet, and the underside of the upper deck forming a planar surface extending from one side of the upper deck to the other side of the upper deck, the planar surface of the underside having a plurality of recesses formed therein, said recesses extending into said planar surface from the underside but terminating before the loading surface of the upper deck, each recess having an outer perimeter, the openings being aligned in the recesses inwardly of the outer perimeters of the recesses wherein the openings are recessed in said planar surface of the underside of the upper deck in said recesses, and wherein the surfaces of the recesses surrounding the openings form channels in fluid communication with the openings for directing the flow of gas that flows across the planar surface to and through the openings to provide ventilation through the pallet.

2. The pallet in accordance with claim 1, wherein the openings comprise slots having a length greater than their widths.

3. The pallet in accordance with claim 2, wherein one group of the slots have greater lengths than other slots.

4. The pallet in accordance with claim 2, wherein one group of the slots have greater widths than other slots.

5. The pallet in accordance with claim 2, wherein the slots are arranged in first and second groups of slots, the first group of slots being arranged in a plurality of parallel rows, the second group of slots being arranged in a plurality of rows that are perpendicular to the rows of the first group of slots, and each of said recesses being elongated and having a greater length than its width and the length of its associated slot wherein the underside includes a first group of elongated recesses and a second group of recesses perpendicular to said first group of recesses such that the flow of gas is directed in both transverse directions.

6. The pallet in accordance with claim 5, wherein the first group of slots are arranged outside the second group of slots.

7. The pallet in accordance with claim 6, wherein the second group of slots has outermost slots, the first group of slots and the outermost slots forming a perimeter group of slots.

8. The pallet in accordance with claim 2, wherein the slots are arranged in first and second groups of parallel rows, which transverse the loading part from one side of the loading part to the other side of the loading part, and the slots being arranged in third, fourth, fifth and sixth groups of parallel rows that are arranged along the sides of the loading part orthogonal to the first and second groups of parallel rows.

9. The pallet in accordance with claim 1 wherein the openings are arranged in four groups with one group of openings in each quadrant of the upper deck.

10. The pallet in accordance with claim 1, the upper deck further having a plurality of handle openings.

11. The pallet in accordance with claim 10, wherein the plurality of openings are located between from the handle openings.

12. The pallet in accordance with claim 11, wherein the plurality of openings are located inwardly from the handle openings.

13. The pallet in accordance with claim 1, wherein the frame section includes a frame center section and a frame floor section, which have a material-fit connection to one another.

14. The pallet in accordance with claim 13, wherein the frame center section includes the spacers which point toward the upper deck and via which the frame center section is connected to the upper deck.

15. The pallet in accordance with claim 14, wherein the upper deck has a reinforcement section that has a material-fit connection with the loading part at their end faces.

16. The pallet in accordance with claim 15, wherein the spacers have elevations which are inwardly offset in steps.

17. The pallet in accordance with claim 1, wherein the upper deck and frame section are formed from one chosen from a plastic, a polymer and a resin.

18. The pallet in accordance with claim 17, wherein the upper deck and frame section are formed from a fire retardant material.

19. The pallet in accordance with claim 1, wherein each of said recesses has a length greater than its width, said recesses including first and second groups of recesses, said lengths of said first group of recesses being oriented to extend transversely across said underside, and said lengths of said second group of recesses being generally orthogonal to said first group of recesses wherein said recesses can direct the flow of gas in both transverse directions across said underside of said upper deck.

20. The pallet in accordance with claim 1, wherein said recesses have tapered distal ends.

21. The pallet in accordance with claim 1, wherein said frame section forms sides of said pallet and side openings at said sides, said recesses being oriented wherein the lengths of recesses extend transversely across said underside wherein the recesses form air passageways for directing the flow of gas across said planar surface of said underside and to and through the side openings to provide ventilation through the pallet.
