  • Patent number: 4850284
    Abstract: A pallet having a pallet deck which is formed from at least two pallet deck members, each of which has finger elements die-cut therein at each leg attachment point. The pallet legs are formed from tubular outer and inner leg elements, and are attached to both pallet deck members by stacking them atop one another and forcibly urging the finger elements on both pallet deck members within the annulus between the nested outer and inner leg elements. With this construction, the pallet deck is increased in strength since two pallet deck members are utilized and the pallet legs have greater strength and are less subject to damage from sideways forces parallel to the pallet applied to them since they are attached to the pallet by the finger elements die-cut in both of the pallet deck members.
