Reinforced plastic pallet
The present invention is to provide a plastic pallet with reinforcements with a great resistance to bending caused by the placing of mechanisms used for transport and storage thereof, such as those caused by racking load. Likewise, the present invention is to disclose a plastic pallet with reinforcements such as inserts, which support a larger load compared with the conventional pallets without substantially incrementing the total weight.
1. A reinforced plastic pallet comprising:
a bottom portion, and a top portion, joined together having improved resistance to deformation caused by at least one of static, racking, or dynamic load;
wherein said bottom portion comprises a bottom deck and a bottom deck cover that are welded together;
wherein said top portion comprises a top deck and a top deck cover that are welded together;
wherein the top deck comprises a plurality of post portions;
wherein the top deck and the top deck cover, the bottom deck and the bottom deck cover are plane surfaces arranged in a sandwich structure;
wherein both plane surfaces are joined together by a rib arrangement;
wherein the rib arrangement in the top deck of the pallet comprises a plurality of square ribbing portions with each square ribbing portion positioned within the perimeter of each post portion and a plurality of diagonal ribs that are formed between the post portions, wherein the plurality of diagonal ribs cross through the square ribbing portions, wherein the plurality of diagonal ribs comprise a first diagonal rib portion and a second diagonal rib portion, wherein the first diagonal rib portion comprises a plurality of ribs extending parallel to each other between two square ribbing portions and the second diagonal rib portion comprises a plurality of ribs extending parallel to each other between two square ribbing portions;
wherein the square ribbing portions and the plurality of diagonal ribs are directly connected to the post portions in the top deck providing an improved rigidity to the area between the post portions; and
wherein the sandwich structure, the square ribbing portions, and the plurality of diagonal ribs provide a reinforced plastic pallet with improved rigidity and strength to flexion of the plane surfaces and resistance to deformation.
2. The pallet according to claim 1 , wherein a set of reinforcement beams is embedded between said bottom deck and said bottom deck cover.
3. The pallet according to claim 1 , wherein the top portion comprises openings for receiving anti slip rubbers and integrated handholds.
4. The pallet according to claim 1 , wherein the top and bottom portions comprise smooth surfaces.
5. The pallet according to claim 1 , wherein an additional reinforcement beam is embedded into said top portion, between said top deck and said top deck cover.
6. The pallet according to claim 1 , wherein no insert is used as reinforcement for the pallet.
7. The pallet according to claim 1 , wherein each one of said plurality of post portions forms a cavity and includes at least one injection port.
8. The pallet according to claim 7 , wherein the post portions are injected with a plastic foam filling the cavity formed in the post portions.
