The present application claims the benefit of U.S. Provisional Patent Application No. 61/056,617, filed on May 28, 2008, which is incorporated herein by reference in its entirety.
BACKGROUNDPallets are used to ship and store a variety of goods. There are several hundred million new pallets produced each year in North America and about 1.2 billion are in use at any given time. Over 90 percent of pallets are made from wood or wood composite with the balance being made from plastic, metal and paper. It is estimated that there are over 3,200 companies in North America producing pallets, from small “garage-type” operations to large companies producing several million pallets per year. There is one conventional size (“Footprint”) pallet, measuring 48 inches by 40 inches that represents about 30 percent of all pallets produced each year. There are another nine “footprints” representing 60 percent of the annual pallet production. The remaining 40 percent of the market includes custom sizes, built to specific end customer requirements.
SUMMARYConventional pallets, such as those explained above, suffer from a variety of deficiencies. Among the many shortcomings of conventional pallets are their weight, the space required to store the pallets, their flammability, their susceptibility to bugs and pests, their inability to be kept clean, the fact that they can result in splinters to handlers and products, labor intensive manufacturing, relatively short life cycle and little or no scrap value.
Embodiments of the invention significantly overcome such deficiencies and provide mechanisms and techniques that provide a wire mesh pallet and a method of producing a wire mesh pallet. The wire mesh pallet is recyclable, lightweight, stackable in a nesting fashion, fire resistant, bug and pest resistant, sanitary, splinter free, strong, lower in cost to manufacture, durable and has scrap value.
Note that each of the different features, techniques, configurations, etc. discussed in this disclosure can be executed independently or in combination. Accordingly, the present invention can be embodied and viewed in many different ways. Also, note that this summary section herein does not specify every embodiment and/or incrementally novel aspect of the present disclosure or claimed invention. Instead, this summary only provides a preliminary discussion of different embodiments and corresponding points of novelty over conventional techniques. For additional details, elements, and/or possible perspectives (permutations) of the invention, the reader is directed to the Detailed Description section and corresponding figures of the present disclosure as further discussed below.
The foregoing will be apparent from the following more particular description of preferred embodiments of the invention, as illustrated in the accompanying drawings in which like reference characters refer to the same parts throughout the different views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention.
The present invention comprises a wire mesh pallet. Instead of conventional wooden pallets, a pallet is formed from a wire mesh. The wire mesh is bent to form a plurality of legs at predetermined places in the mesh resulting in a pallet formed from a single piece of mesh. The invention is a unique way to construct a pallet by maximizing the strength and stiffness of the product at the lowest possible weight and efficiency to manufacture, thereby making the sale of the product possible in comparison with pallets made from other materials.
The presently disclosed wire mesh pallet is 100 percent recyclable and lightweight—about one half the weight of a conventional wooden pallet. The wire mesh pallet is stackable. The pallets can be nested when stacking, allowing more than double the number of pallets to be shipped from the factory and on return loads. The wire mesh pallet is also fire resistant. The wire mesh pallets will not burn, allowing pallets to be stored indoors and reducing insurance costs. The wire mesh pallet will not harbor bugs or pests and can be certified for export shipments without treatment. The wire mesh pallet is also easier to clean and keep clean, and produces no splinters to damage hands or product. The wire mesh pallet offers higher strength and stiffness as well as low labor cost to produce. Further, the wire mesh pallet has a long life cycle and is easy to repair as well as having scrap value at end of life cycle, with no disposal costs.

In order to prevent the wire mesh surface and legs from deforming or flexing under load conditions, at least one truss device is added to the structure. Referring now to

Referring now to
The truss devices are used to limit or prevent spreading and deformation of the wire mesh pallet when a load is placed on the wire mesh pallet. In some embodiments, it may be desirable to allow a predetermined amount of flex, or to allow an area of the wire mesh pallet to flex while other areas of the wire mesh pallet have limited or no flex. Also, while the drawings show a particular number of truss devices, it should be realized that any number of truss devices could be used. Further, the truss wires may be of any orientation, for example, extending diagonally across the wire mesh pallet wherein two diagonal truss wires form an “X” shape.

The wire mesh pallet can be made from a variety of materials, including but not limited to steel, stainless steel, aluminum and plastic. The wire mesh pallet may further be provided with a coating. The coating process can take place before the wire mesh is formed into the wire mesh pallet or the coating process can take place after the wire mesh has been formed into a wire mesh pallet.
A flow chart of the presently disclosed method is depicted in
Referring now to
Processing block 210 discloses bending the wire mesh at a plurality of predetermined locations to form a plurality of support legs. The mesh is typically bent to form three support legs. The gauge of the wire used and location of the legs will determine the carrying load of the pallet and the ability of the pallet to be accessed. There may be “2-way” access in which a fork truck or pallet jack can only access the pallet from two of the four sides, or “4-way” access wherein the fork truck or pallet jack can access all four sides of the pallet.
Processing block 212 states adding at least one truss device to the wire mesh pallet, the truss device capable of limiting an amount of flex of the wire mesh pallet; the truss device in mechanical communication with the wire mesh pallet, the truss device traversing at least a portion of the wire mesh pallet. As shown in processing block 214 the truss device comprises a truss wire, the truss wire traversing at least a section of the wire mesh pallet. As shown in processing block 216 the truss device comprises a truss clip, the truss clip traversing at least a section of a leg of the wire mesh pallet. As shown in processing block 218 the truss device comprises a truss leg wire, the truss leg wire traversing at least a section of a leg of the wire mesh pallet. As shown in processing block 220 the truss device comprises a cover, the cover traversing at least a section of the wire mesh pallet.
Processing continues on
Processing block 228 recites coating the wire mesh. As shown in processing block 230, the coating is applied before forming the wire mesh pallet. As shown in processing block 232, the coating is applied after forming the wire mesh pallet.
The finished pallets can then be nested to maximize the “Cube” in a container for both outbound (from the original point of manufacturing) and return shipping (commonly called “Closed loop”).
