Abstract
A knock-down pallet is constructed of a plurality of releasably interlocking aluminum members of one of two types. A unique fastening device is used to achieve, in simple manner without special tools or skill, the interlocking of a plurality of spaced-parallel deck-forming members to two, three or more spaced and parallel stringer members of rectangular cross-section to provide a one- or two-deck two-way or four-way pallet construction. A stop means prevents longitudinal movement of the deck members transverse of the stringer members. A fence structure formed of similar releasably interlocking members also is described.

A pallet construction comprising:
- at least two spaced-apart substantially parallel longitudinally-extending aluminum members,
- a plurality of deck-forming aluminum members contacting and extending at least between the at least two longitudinally-extending members generally transverse thereto in spaced-apart relation,
- each of said plurality of deck-forming members having at least one planar portion cooperating with the at least one planar portion of the others of said plurality of deck-forming members to provide a planar pallet deck surface which extends substantially the length of said longitudinally-extending members,

- said snap-fit means including a first and second pair of spaced channels situated on said longitudinally-extending member, in each pair the channels opening in opposite directions in the direction of extension of the longitudinally-extending member, and channel-engaging members formed on each of said deck-forming members constructed to snap fit into said pairs of spaced channels,
- said stop means at each said intersection comprising two projections on each of the longitudinally-extending members engaging respective openings is said deck-forming members.
A pallet construction comprising:
- at least two spaced-apart substantially parallel longitudinally-extending aluminum members,
- a plurality of deck-forming aluminum members contacting and extending at least between the at least two longitudinally-extending members generally transverse thereto in space-apart relation,

- each of said longitudinally-extending members including a continuous generally rectangularly cross-sectioned portion, and a plurality of short continuous portions received in sliding fit relationship with said continuous portion longitudinally spaced-apart from each other to provide openings for receiving fork-lift tines through the longitudinally-extending members transverse thereof,
- said continuous portion and said short portions having identical cross-sectional shapes.
A pallet construction comprising:
- at least two spaced-apart substantially parallel longitudinally-extending aluminum members,
- a plurality of deck-forming aluminum members contacting and extending at least between the at least two longitudinally-extending members generally transverse thereto in spaced-apart relation,
- each of said plurality of deck-forming members having at least one planar portion cooperating with the at least one planar portion of the other of said plurality of deck-forming members to provide a planar pallet deck surface which extends substantially the length of said longitudinally-extending members,
