This invention relates generally to cardboard structures, and particularly those for use in industrial pallets. The cardboard structure comprises layers of corrugated cardboard with corrugations running in different directions. This allows the resultant structure to take significant amount of stress in different directions. A pallet structure utilizing this cardboard also has feet formed from a single sheet of thin plastic material. It is free from sharp corners and stress risers and has ribs and ridges and valleys giving added strength to the resultant structure. A pallet having such feet has stringers made of a sandwich construction of corrugated cardboard covered by layers of corrugated cardboard having corrugations running in a direction perpendicular to the corrugations in the sandwich stringers.
A pallet consisting of a substantially flat body, a plurality of slots in the body and feet positioned in the slots. Each of the feet is readily molded from a suitable plastic and has an open upper end and a downwardly tapered cavity in which an internal support surface is formed. In stacking of pallets, the foot of the top pallet telescopes downwardly into the foot of the bottom pallet to a supported position on the internal support surface in which the pallet bodies are maintained in a spaced relation so that they can readily be separated when desired.
A reusable shipping skid for transporting arcuate shaped loads. The skid has a unitized construction including a plurality of parallel runners interconnected at their opposite ends by a pair of cross members which are removably and adjustably positionable on the runners to accommodate loads of different length. An upstanding support having an arcuate plate is removably mounted at the center of the runners for supporting the curved underside of the load. The skid is adapted for movement through muddy or sandy terrain at a job site and can be easily disassembled for compact return shipment.
A polymer pallet leg for a cardboard pallet base including a first truncated cone, a second truncated cone within said first truncated cone inversely positioned with respect thereto, a rim surrounding and offset below a top edge of said first truncated cone, and a plurality of locking tabs extending outwardly from a top edge of the first truncated cone. The locking tabs engage with corresponding tab holes of a cardboard pallet about a pallet leg hole. The second truncated cone includes a flat surface for engaging with any object placed on the pallet and is about the same height as the top edge of the first truncated cone. An optimal braking tab can also be provided for engaging the cardboard further locking the leg in position. A pallet leg insert engages into the second inverted cone for attaching a bottom pallet base to the polymer pallet legs.
A manually insertable leg for cooperating with a load platform and a pallet formed by assembling the load platform and a plurality of legs, wherein the platform is gripped between flanges on the leg in such a manner as to facilitate ready assembly of the pallet at a location of use and as to preclude undesirable disassembly of the pallet during use.
A composite article useful as a material of construction made of a plurality of substantially aligned, individual pieces of corrugated cardboard cut from scrap corrugated boxes or sheets. The corrugated pieces lie in a shingle-like configuration, a bridge-like configuration, or a combination thereof and form multiple, generally planar layers of individual corrugated cardboard pieces having a length only a fraction of the full length of the article. The material of construction is particularly useful in making shipping pallets to replace wood pallets currently in use.
