Abstract

A pod (10) arranged to support a load (14) and absorb shock experienced by the load includes a body (18) and a face (16) spaced from the body and oriented to be mounted to the underside of a load placed on the face. At least one spring assembly (20) is disposed around the periphery of the body and extends between the body and the face to absorb shock experienced by the load. The face and the at least one spring assembly form a cavity configured to receive a body of a like pod disposed thereabove when arranged in a stacked orientation. The pod may also be incorporated into a pallet assembly (90, 110).

Claims

1. A pod for supporting a load comprising:

a rigid member;

a planar member having an opening larger than the rigid member, the rigid member and the planar member spaced from one another such that the rigid member is aligned with the opening in the planar member; and

a plurality of connection members extending from the rigid member to the planar member, each of the connection members having a wave-shaped cross section.

2. The pod of claim 1 wherein the rigid member, the planar member and the plurality of connection members are integrally molded together as a unitary construction.

3. The pod of claim 2 wherein the planar member is annular.

4. The pod of claim 2 wherein the rigid member includes a peripheral wall extending toward the planar member generally perpendicular to the planar member, the plurality of connection members extending from the peripheral wall to the planar member.

5. The pod of claim 2 further including a plurality of window openings, each defined between an adjacent pair of the plurality of connection members, the planar member and the rigid member.

6. The pod of claim 1 wherein each of the plurality of connection members extends at an angle outwardly from the rigid member to the planar member.

7. The pod of claim 1 wherein the opening in the planar member defines an inner peripheral edge and the plurality of connection members are connected to the inner peripheral edge of the planar member.

8. The pod of claim 7 wherein the planar member extends radially outwardly from the plurality of connection members.

9. An assembly including a plurality of the pods of claim 1 arranged in a spaced-apart relationship below a load, the load supported on the plurality of pods.

10. The assembly of claim 9 wherein the load contacts one of the rigid member and the planar member.

11. A pod for supporting a load comprising:

a base member having a central outer surface and an outer peripheral edge;

a peripheral member having an opening larger than the base member central outer surface, the opening defined by an inner peripheral edge of the peripheral member; and

a plurality of connection members extending from the outer peripheral edge of the base member to the inner peripheral edge of the peripheral member, each of the connection members including a plurality of alternating non-parallel portions, the base member, the peripheral member and the plurality of connection members are integrally molded together as a unitary construction.

12. The pod of claim 11 wherein the peripheral member is annular.

13. The pod of claim 11 further including a plurality of window openings, each defined between an adjacent pair of the plurality of connection members, the peripheral member and the base member.

14. The pod of claim 13 wherein each of the plurality of connection members extends at an angle outwardly from the outer peripheral edge of the base member to the inner peripheral edge of the peripheral member.

15. An assembly including a plurality of the pods of claim 11 arranged in a spaced-apart relationship below a load, the load supported on the plurality of pods.

16. The assembly of claim 15 wherein the load contacts one of the base member and the peripheral member.

17. A pod for supporting a load comprising:

a base member having a central outer surface and an outer peripheral edge;

a peripheral member having an opening larger than the base member central outer surface, the opening defined by an inner peripheral edge of the peripheral member; and

a plurality of connection members extending at an angle outwardly from the outer peripheral edge of the base member to the inner peripheral edge of the peripheral member, each of the connection members including a plurality of alternating non-parallel portions that form a wave-shaped cross section, a window opening defined between each adjacent pair of the plurality of connection members, wherein the base member, the peripheral member and the plurality of connection members are integrally molded together as a unitary construction.

18. An assembly including a plurality of the pods of claim 17 arranged in a spaced-apart relationship below a load, the load supported on the plurality of pods.

19. The assembly of claim 18 wherein the load contacts one of the base member and the peripheral member.
