BACKGROUNDPlastic pallets may include an upper deck and a lower deck (or runners) with columns between the upper deck and the runners to provide openings for receiving the tines of a forklift. The columns and the outer periphery of the upper deck often are impacted by the tines of the forklift Therefore, the columns and outer periphery of the upper deck suffer most of the damage experienced by plastic pallets.
SUMMARYA pallet according to one embodiment of the present invention provides reinforced columns and a more resilient periphery of the upper deck. The pallet includes an upper portion having an upper deck and a lower portion, which may include runners. A plurality of outer column portions have peripheral walls extending from the upper portion to the lower portion.
A plurality of inner column portions are received within the outer column portions. Each inner column portion may include a plurality of projections on an outer edge of the inner column portion.
The pallet may include at least one reinforcement member, in which case the plurality of projections are spaced apart to provide inner channels and outer channels formed through the outer column portions.
The plurality of outer column portions may include a plurality of tabs received in openings adjacent the inner column portions. A shoulder portion may be formed adjacent each inner column portion, wherein the openings are formed in the shoulder portions.
The inner column portions may be formed integrally with the lower portion and the outer column portions may be formed integrally with the upper portion.
The upper deck includes a plurality of ribs formed on the underside. A periphery of the upper deck may include ribs in a honeycomb pattern, to provide a more resilient area. The periphery is more resistant to damage from fork tine impact.
A pallet 10 according to one embodiment of the invention is shown in
As shown in
As can also been seen in
In accordance with the provisions of the patent statutes and jurisprudence, exemplary configurations described above are considered to represent a preferred embodiment of the invention. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope. For example, although the inner column portion 21 is shown as formed integrally with the lower portion 18, and the outer column portion 20 with the upper portion 12, the inner column portion 21 could be formed integrally with the upper portion 12 and the outer column portion 20 could be formed integrally with the lower portion 18.

7) The pallet of claim 6 wherein the inner column portions are formed integrally with the lower portion and wherein the outer column portions are formed integrally with the upper portion.
8) The pallet of claim 1 wherein the inner column portions are formed integrally with the lower portion and wherein the outer column portions are formed integrally with the upper portion.
9) The pallet of claim 8 wherein the lower portion includes a plurality of runners, wherein the columns extend from intersections of the plurality of runners.
10) The pallet of claim 1 wherein the upper deck includes a plurality of ribs, the upper deck including a peripheral portion in which the plurality of ribs are arranged in a honeycomb pattern.
11) The pallet of claim 1 wherein the outer column portions each include a peripheral wall having a plurality of ribs along an interior surface of the peripheral wall.
12) The pallet of claim 11 further including a plurality of latches formed within the outer column portions, wherein the plurality of latches snap fit to connect to the inner column portions.
13) A pallet comprising:
- an upper portion having an upper deck;
- a lower portion;
- a plurality of outer column portions having peripheral walls with outer channels therethrough, the outer column portions extending from the upper portion to the lower portion;
- a plurality of inner column portions each including a plurality of projections on an outer edge of the inner column portion, the plurality of projections spaced apart to provide inner channels, each inner column portion received within one of the outer column portions; and
- at least one reinforcement member received in the inner channels and the outer channels.
14) The pallet of claim 13 wherein each of the plurality of outer column portions includes a plurality of tabs received in openings adjacent the inner column portions.
