DETAILED DECRIPTION OF THE PREFERRED EMBODIMENTS

[0048] Referring now to the drawings, FIGS. 1, 2A, and 2B depict the first preferred embodiment of the pallet assembly [10] of the present invention. The pallet assembly of the present invention [10] comprises a top plate [20], a load-force plate [30], a runner [60], a pallet integrated module [55], and a plurality of load blocks [50] disposed between the load force plate [30] and the runner [60].

[0049] FIG. 2A depicts a layered top view depicting the top plate [20], the load-force plate [30], and a plurality of load blocks [50] with aligning dowels [70] symmetrically and equally positioned on the runner [60] of the first preferred embodiment of the pallet assembly [10] of FIG. 1.

[0050] The outer surface of the pallet assembly of the present invention [10], the top plate [20], the load-force plate [30], and the runner [60] preferably have generally, square shapes. The load blocks [50] are symmetrically distributed about the pallet assembly [10] between the load-force plate [30] and the runner [60] such that a forklift (not shown) can approach the pallet assembly [10] from any of the four side surfaces thereof.

[0051] FIG. 2B depicts a layered bottom view of the top plate [20], the load-force plate (cross form) [30], the pallet integrated module [55], the nine (9) load blocks [50] with aligning dowels [20] symmetrically and equally positioned on the runner. The pallet integrated module [55] abuts the center load block of the nine load blocks [50] of the first preferred embodiment of the pallet assembly [10] of FIG. 2A. The pallet integrated module [55] is preferably battery powered. The battery unit for the pallet integrated module lasts for the entire life of the unit. The pallet integrated module [55] also has antennas, microprocessors, and memory capability. The pallet integrated module [55] monitors temperature, mechanical shock, humidity, and time. The pallet integrated module [55] has a unique electronic identity programmed at the factory when the pallet is assembled. The pallet integrated module [55] also can be programmed at the customer's location, to identify the material that is on the pallet. This customer programming will be changed each time the pallet assembly of the present invention [10 and 110] makes a cycle from the loading location to the unloading location and back to the customer's loading location. The packaging of the pallet integrated module [55] is robust enough to survive contact with pallet jacks and forklifts.

[0052] FIG. 3A depicts a layered top view depicting the top plate [20], the load-force plate (cross-form) [30], the pallet integrated module [55], the nine (9) load blocks [50] symmetrically and equally positioned on the runner [60] of the first preferred embodiment of the pallet assembly [10] of the present invention.

[0053] FIG. 3B depicts a layered top view depicting the top plate [20], the load-force plate (X-form) [40], the pallet integrated module [55], the nine (9) load blocks [50] symmetrically and equally positioned on the runner [60] of the second preferred embodiment of the pallet assembly [110] of the present invention.

[0054] FIG. 4 depicts an assembly view of the top plate [20] of the pallet assembly [10, and 110] of the present invention.

[0055] FIG. 5 depicts an assembly view of the load-force plate [30] having a cross-form configuration for the first and second preferred embodiments of the pallet assembly [10 and 110] of the present invention.

[0056] FIG. 6 depicts an assembly view of the load-force plate [40] having an X-form configuration for the second preferred embodiment of the pallet assembly [110] of the present invention.

[0057] FIG. 7 depicts an assembly view of the runner [60] for the first and second preferred embodiments of the pallet assembly [10 and 110] of the present invention.

[0058] FIG. 8A depicts an exploded detail view of a load block [50] for use in the first and second preferred embodiments of the pallet assembly [10 and 110] of the present invention.

[0059] FIG. 8B depicts an exploded detail view of the pallet integrated module [55] for in the first and second preferred embodiments of the pallet assembly [10 and 110] of the present invention.

[0060] FIG. 9A depicts a detailed view of the first preferred embodiment of the pallet assembly of the present invention with antennas mounted in the load force plate (cross form) [30] serving as a signal extender on the load-force plate (cross form) [30] of the first and second preferred embodiments of the pallet assembly [110] of the present invention. The upper antennas [34A and 34B] run parallel to each other and are embedded in the upper center bar [31] of the cross of the load force plate (cross form) [30] and the lower antennas [37A and 37B] run parallel to each and are embedded in the lower center bar [32] of the cross of the load force plate (cross form) [30].

[0061] The load force plate depicted in FIG. 1A is the cross-form load force plate [30]. However, it is understood that one skilled in the art can readily apply the principles of the signal extender of FIG. 9A to the load-force plate (X-form configuration) [40].

[0062] FIG. 9B depicts a detailed view of the first preferred embodiment of the pallet assembly of the present invention with antennas mounted in the load force plate (cross form) [30] serving as an antenna contact tracking sensor on the load-force plate (cross form) [30] of the first and second preferred embodiments of the pallet assembly [10 and 110] of the present invention. The upper antennas [34A and 34B] run parallel to each other and are embedded in the upper center bar [31] of the cross of the load force plate (cross form) [30] and the lower antennas [37A and 37B] run parallel to each other and are embedded in the lower center bar [32] of the cross of the load force plate (cross form) [30]. The antennas [34A and 34B] and [37A and 37B] formed in the load force plate (cross form) [30] drop down into a hole formed at the juncture of the cross to contact the tracking sensor, which is the pallet integrated module [55].

[0063] The load force plate depicted in FIG. 9B is the cross-form load force plate [30]. However, it is understood that one skilled in the art can readily apply the principles of the signal extender of FIG. 9B to the load-force plate (X-form configuration) [40].

[0064] FIG. 9C depicts a detailed view of the first preferred embodiment of the pallet assembly of the present invention [10] with antennas mounted in the load force plate (cross form) [30] serving as an antenna repeater where there is no electrical contact to the tracking sensor (pallet integrated module [55]).

[0065] The antenna repeaters [38A and 38B] are embedded in and run parallel to each other in the center bar of the cross of the load force plate (cross form) [30] and make no electrical contact with the pallet integrated module (tracking sensor) [55].

[0066] The load force plate depicted in FIG. 9C is the cross-form load force plate [30]. However, it is understood that one skilled in the art can readily apply the principles of the signal extender of FIG. 9C to the load-force plate (X-form configuration) [40].

[0067] FIG. 10A depicts a flow chart for the antenna that is electrically connected to the pallet integrated module of FIG. 9A and 9B.

[0068] FIG. 10B depicts a flow chart depicting the functioning of the antenna repeater that is printed onto or embedded into the load-force plate, that acts like a signal repeater, and is not directly connected to the pallet integrated module.

[0069] The coating is smooth, which enables a more thorough cleaning. There is no place for dirt, bacteria, mold, fungus, microbes, or viruses to hide.

[0070] Another advantage of the pallet assembly [10 and 110] of the present invention is that the species of wood selected for the pallet assembly [10 or 110] varies and is dependent upon the cargo being transported. Different species of wood are selected for the top plate [20], the load-force plate [30 or 40], the plurality of load blocks [50], and the runner [60] depending upon the weight of the cargo. By changing the species of wood, the strength and weight of the pallet assembly can be configured to meet the requirements of the customer. If the customer is shipping steel or cast parts, the strength of the pallet components must be reconfigured to accommodate the weight of these parts. In this example, the pallet components, a dense wood such as Baltic Birch or oak is used. If the customer is shipping a light load, such as a child's game or toy, a less dense wood, such as pine is selected. As the wood species are changed, the pallet cost and weight can be reconfigured to meet the requirements of the shipping industry while also meeting the needs of the customer for weight reduction and cost. All our additives are of such a small micron size, they don't cause the polyurea to be off from ratio. Off ratio polyurea will not cure properly and will not have all the properties of a properly cured polyurea.

[0071] Dowels, preferably wooden, are used to accurately locate the top plate, the legs, and the bottom plate within very tight tolerances. The pallet of the present invention can be readily assembled with the wooden dowels that facilitate attachment of transverse deck boards to parallel stringers in a quick and efficient manner. Also, the dowels provide structural stability during the adhesive curing and prevent rotation of the blocks during assembly. This build technique enables tight tolerances between all the components. For this equipment to properly pick and lift the pallet, the pallet must be built to tight tolerances.

[0072] The pallet integrated module [55] collects journey data on location, temperature, humidity, and shock along with “store forward” capability during unconnected times of the journey. All this data is sent to the cloud for parsing, future queries, report generation and alert capability. The module is capable of “over the air” software upgrades and has various modes of connectivity not only to mitigate connectivity costs but to seamlessly interact with the complete ecosystem.

[0073] The pallet integrated module [55] is programmed and then the pallet assembly of the present invention is sent to the customer who is renting or leasing the pallet. Information about the contents of the pallet is programmed into the electronics at the location of the customer. During shipping, the electronics monitors, temperature, G force, humidity, and other elements versus time. This data can be accessed at various places along the shipping route. The data collected helps ensure that contents of the pallet assembly of the present invention are not exposed to inappropriate temperatures or other harmful environmental conditions. The data also helps to prove that the pallet contents were properly cared for during shipping. The top plate [20], the load-force plate [30 and 40], the load blocks [50], and the runner [60] are preferably joined with an adhesive.

[0074] Suitable polymeric materials include, but are not limited to, polyolefins, polyesters, polyurethanes, polyureas, epoxies, polyurea-polyurethane hybrids, and combinations thereof. Desirably, the polymeric material comprises polyurea, polyurethane, or a combination thereof (see for example U.S. patent application Ser. No. 09/399,271 entitled “Novel Pallets” (Phillips; et al.).

[0075] The pallet assemblies [10, and 110] of the present invention are comprised of a conventional pallet coated with a fast-curing elastomeric material using spray techniques whereby a homogeneous, non-porous, and monolithic coating is formed. The desired elastomeric materials used are prepared by initiating the reaction of an aliphatic or aromatic isocyanate-terminated compound or polymer with an aliphatic or aromatic amine-terminated compound or polymer immediately before applying the elastomeric material to the surface to be coated. Desirably, the reactive components (i.e., isocyanate-containing and amine-containing materials) are mixed directly in a spray gun used to apply the elastomeric material. The thickness of the elastomeric coating can easily be controlled by conventional application means. It is important that the thickness of the elastomeric coating be enough so that the coating is resistant to impact that is normal in use. The desired thickness of the elastomeric coating on the pallet material is between approximately 1 mm and 250 mm, with the most desired thickness of between 60 mm and 75 mm.

[0076] The pallet assemblies of the present invention comprise one or more polymeric materials optionally in combination with one or more filler materials. Suitable polymeric materials include any polymeric material capable of being formed into a polymeric board or sheet. Suitable polymeric materials include, but are not limited to, polyolefins, polyesters, polyurethanes, polyurea, epoxies, polyurea-polyurethane hybrids, and combinations thereof. Desirably, the polymeric material comprises polyurea, polyurethane, or a combination thereof. More desirably, the polymeric material comprises a polyurethane foam. The filler material may be organic or inorganic filler material in the form of particulate material, fibers, fabrics, rods, or any other structural reinforcement. Suitable inorganic filler materials include, but are not limited to, calcium carbonates, clays, silica, sand, glass fibers and carbon fibers. Suitable organic fillers include, but are not limited to, fibers such as cotton, rayon, nylon, and other polymeric fibers, such as polyolefin fibers and aramid fibers.

[0077] The deflection, stress, strain testing of the load-force plate (cross-form) best compared to X-FORM load force plate (X-form) and the standard pallet. ISO 8611 Rack Test Simulation (2750 lb.) were conducted, and the results are shown below:

[0086] The load-force plate (cross-form) performed best. The stress was 3.688e{circumflex over ( )}−03 after the 2750 lb. load was applied.

[0087] The pallet assembly of the present invention is designed to meet the requirements of the customers, as well as international standards for strength, flex, flame, and smoke requirements. The thin top plate, the load-transfer plate, the support blocks, and the runner will all be coated in a spray or a dip coating (powder coating or fluid bed coating) to protect the wood and to add strength to the pallet assembly of the present invention.
