Abstract

A modular pallet is made up of plural injection molded plastic pallet members, each of which has a plurality of posts spaced apart from each other and depending from a deck portion of the pallet member. The pallet members may be rectangular, square or of irregular shape but operable to provide either a square or rectangular shaped pallet when arranged in predetermined patterns in opposing deck sections of the pallet. The pallet members have cooperating projections and recesses formed in respective ones of the posts and the pallet members of one deck section overlie and interlock with at least two pallet members of the other deck section. Releasable fasteners comprising deflectable tines may be projected through openings in the cooperating projections and recesses of each pallet member to secure the pallet members of the opposing deck sections to each other to form the assembled modular pallet. The pallets may be square or rectangular and made up of plural identical pallet members in each deck section or no more than two different pallet members used to form a deck section.

Claims

1. A pallet comprising plural pallet members in each of two opposed first and second deck sections, said first deck section is defined by four substantially rectangular pallet members having respective major and minor axes and said second deck section is defined by four rectangular pallet members having respective major and minor axes;

each of said pallet members defining said first deck section is coupled to two of said pallet members defining said second deck section and in overlapping relationship therewith each of said pallet members defining said second deck section is coupled to two of said pallet members defining said first deck section and in overlapping relationship therewith; and

wherein the major axis of each pallet member is parallel to the major axis of one of the pallet members to which it is coupled and a minor axis of the other pallet member to which it is coupled.

2. The pallet set forth in claim 1 wherein:

the major axis of each pallet member is parallel to the respective minor axes of two other pallet members of the same deck section and the major axis of one other pallet member of said same deck section.

3. The pallet set forth in claim 2 wherein:

said pallet members are identical and the pallet members of each deck section define a generally square-shaped deck section, each of said pallet members being adjacent two other pallet members of the same deck section and being diagonally opposite the remaining pallet member of said same deck section.

4. The pallet set forth in claim 1 including:

a plurality of posts extending between said deck sections and engaged with the pallet members of one of said deck sections, each of said posts including at least one of a projection and recess formed thereon and cooperating with a corresponding one of a recess and projection of an opposed pallet member of the other deck section.

5. The pallet set forth in claim 4 wherein:

said projections are triangular in cross section.

6. The pallet set forth in claim 4 wherein:

said projections are oblong in cross section.

7. The pallet set forth in claim 4 wherein:

said projections are square in cross section.

8. The pallet set forth in claim 4 wherein:

said projections are half cylindrical in cross section.

9. The pallet set forth in claim 4 including:

fastener means for releasably interconnecting one pallet member with an opposing pallet member.

10. The pallet set forth in claim 9 wherein:

said fastener means comprises a shank portion and opposed resiliently deflectable tines connected to said shank portion and said tines are adapted to be projected through respective openings formed in said pallet members in registration with each other to secure said pallet members to each other.

11. The pallet set forth in claim 10 wherein:

said openings in said pallet members are formed in said cooperating projections and recesses.

12. The pallet set forth in claim 1 wherein:

said pallet members are formed of molded plastic.

13. The pallet set forth in claim 1 wherein:

each pallet member has a planar deck portion with a plurality of posts projecting from said deck portion, said posts including surface means adapted to be in registration with corresponding surface means of opposing posts of an opposing pallet member to maintain said first and second deck sections in a predetermined spaced relationship.

14. The pallet set forth in claim 13 wherein:

each post has at least one projection and one recess formed therein, the projection portion of each post being operable to be in registration with the recess of a post of a cooperating pallet member and the recess formed in the first mentioned pallet member being in registration with a projection formed on the post of the cooperating pallet member.

15. The pallet set forth in claim 14 wherein:

a projection formed on a post is adjacent to a recess formed on said post.

16. The pallet set forth in claim 13 wherein:

said posts of said pallet member are integrally formed therewith.

17. A pallet comprising two opposed, generally square shaped deck sections, each of said deck sections being made up of four pallet members, each of said pallet members defining a corner of said deck section, each of said pallet members being adjacent to two other pallet members of the same deck section and being diagonally opposite the remaining pallet member of said same deck section, each of said pallet members defining one of said deck sections is coupled to two of said pallet members defining the other of said deck sections and in overlapping relationship therewith and each of said pallet members defining said other deck section is coupled to two of said pallet members defining said one deck section and in overlapping relationship therewith;

each of said pallet members including a deck portion and a plurality of posts projecting substantially normal to said deck portion, each of said posts including at least one of a projection and recess formed thereon and cooperating with a corresponding one of a recess and projection of an opposed pallet member of the opposed deck section; and

plural fastener members operable to releasably interconnect said deck sections at selected ones of said posts for securing said deck sections together to form a modular pallet wherein any one of said pallet members defining a corner of either of said deck sections maybe replaced by an identical pallet member to form said pallet.
