Abstract

A pallet having first and second decks with at least two post assemblies extending between the first and second decks to maintain the first and second decks at a distance from one another. Each post assembly includes an outer post member including a substantially hollow body extending axially from a base connected to the first deck to a free end and an inner post member including a body extending axially from a base connected to the second deck to a free end. The inner post body free end is configured to be received in the outer post body with the inner and outer posts positioned relative to one another such that at least one of the post free ends contacts the respective opposed deck and supports the first and second decks in spaced relationship.

Claims

1. A pallet comprising:

first and second decks;

at least two post assemblies extending between the first and second decks to maintain the first and second decks at a distance from one another, each post assembly comprising;

an outer post member including a substantially hollow tubular body extending axially from a base connected to the first deck to a free end spaced therefrom, the tubular body defining an outer post inner wall surface therein and the free end defining the perimeter of the hollow tubular body; and

an inner post member including a body extending axially from a base connected to the second deck to a free end spaced therefrom, the inner post member body defining an inner post outer wall surface, the inner post member including a groove extending about at least a portion of the perimeter of the inner post base;

wherein, in an assembled configuration, the inner post body free end is received within the outer post body with the inner and outer posts positioned relative to one another and to the first and second decks such that at least a portion of the outer post hollow body free end is received in the inner post groove such that the outer post hollow body free end is radially supported and restrained by the second deck; and

wherein, on at least one of the post assemblies, the inner post outer wall surface includes at least one external barb and the outer post inner wall surface includes at least one internal barb, the inner post barb engaging the outer post barb when the inner post body free end is received within the outer post body and interconnects the first and second decks in the assembled configuration.

2. The pallet according to claim 1 wherein at least one of the inner post outer wall surface is defined by a continuous wall extending between the inner post base and the inner post body free end.

3. The pallet according to claim 2 wherein at least one vertical rib extends between opposed portions of the continuous wall.

4. The pallet according to claim 3 wherein the opposed portions of the continuous wall each have at least one external barb thereon.

5. The pallet according to claim 1 wherein the inner post outer wall surface is defined by a plurality of circumferentially spaced finger members extending between the inner post base and the inner post body free end.

6. The pallet according to claim 5 wherein at least one vertical rib extends between opposed finger members.

7. The pallet according to claim 6 wherein the opposed finger members each have at least one external barb thereon.

8. The pallet according to claim 1 wherein at least one bridge portion is defined within the inner post groove and the outer post free end includes at least one corresponding notch configured to receive the at least one bridge portion.

9. The pallet according to claim 1 wherein each barb has a tapered surface facing toward its respective post free end and a flat engagement surface facing toward its respective post base end.

10. The pallet according to claim 9 wherein each flat engagement surface extends at a substantially right angle relative to an axis extending along the respective post member.

11. The pallet according to claim 9 wherein each flat engagement surface extends at an acute angle relative to an axis extending along the respective post member.

12. The pallet according to claim 9 wherein each flat engagement surface extends at an obtuse angle relative to an axis extending along the respective post member.

13. The pallet according to claim 1 wherein each barb has an arcuate contoured edge.

14. The pallet according to claim 1 wherein the inner post outer wall surface includes a plurality of external barbs configured to engage a plurality of internal barbs on the outer post inner wall surface.

15. The pallet according to claim 14 wherein the external barbs have differing axial widths and are varied axial spacing therebetween and the internal barbs have differing axial widths and are varied axial spacing therebetween such that the external and internal barbs only engage in a given orientation relative to one another.

16. The pallet according to claim 14 wherein the external barbs and the internal barbs are spaced such that in a first orientation the external barbs engage the internal barbs but the first and second decks are moveable relative to one another and in a second orientation the external barbs engage the internal barbs such that the first and second decks are axially fixed relative to one another.

17. The pallet according to claim 16 wherein a compressible material is provided within the post assembly and compresses as the barbs are moved from the first orientation to the second orientation.

18. The pallet according to claim 1 wherein the inner and outer post members define a substantially sealed interior within the post assembly.

19. The pallet according to claim 18 wherein a gasket is provided within the inner post groove.

20. The pallet according to claim 18 wherein the first or second deck includes a through hole which is sealed via a self expanding sealing foam.

21. The pallet according to claim 18 wherein the first or second deck includes a through hole which is sealed via a cap.
