Patent number: 4198034Abstract: 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.Type: GrantFiled: December 20, 1977Date of Patent: April 15, 1980Assignee: Extrados Company LimitedInventor: Ferdinand M.
