The present invention relates generally to pallets. Pallets are often used to store and transport goods. The pallets maintain the goods at a distance above the floor such that they can be readily lifted and moved by a fork of a lift truck. Some pallets have stringers or double decks forming openings, which receive the forks of the lift truck. Other pallets are nestable within one another to facilitate storage and transport when empty. Both types of pallets include an upper deck supported by columns extending downwardly from the upper deck.
In some pallets, a portion of the upper deck protrudes outwardly relative to an outermost surface of the column. As a result, adjacent pallets may experience “shingling,” in which the protruding part of the upper deck of one pallet catches on top of an adjacent pallet, such that the upper pallet is suspended off of the floor. This makes the stack of goods on the pallet uneven and potentially unstable.
A pallet according to one embodiment includes a deck from which a plurality of columns extend downwardly. At least a portion of the deck protrudes outwardly from and may slightly overlap a portion of the outer columns. In order to prevent shingling, a plurality of ribs or other protrusions are formed on the outer surface of the columns in order to create a surface more flush with the upper deck. As a result, the ribs of one pallet would prevent the protruding portion of the deck of an adjacent pallet from catching underneath the protruding portion of the deck.
These and other features of the application can be best understood from the following specification and drawings, the following of which is a brief description.
A pallet 10 according to one embodiment of the present invention is shown in
The upper deck 12 includes flange portions 22, which protrude outwardly relative to outermost surfaces of the columns 16, 18 and slightly overlap the outer surfaces of the columns 16, 18. The lower portion 14 further includes a lower flange 26 about the periphery of the lower portion 14, including columns 16, 18 and runners 20. The lower flange 26 also protrudes outwardly of the outermost surfaces of the columns 16, 18.
In order to prevent shingling, the outer surfaces of the columns 16, 18 are provided with anti-shingling protrusions. In the embodiment shown, the protrusions 24 are a plurality of parallel, vertically oriented ribs 24; however, other arrangements of ribs 24 or other protrusions could be used.
Referring to
Although a pallet with runners 20 has been shown, the ribs 24 could also be provided on columns (or feet) of a nestable pallet to prevent shingling. A nestable or non-nestable pallet integrally molded as a single piece could include the anti-shingling protrusions. Other types of pallets may also benefit from the anti-shingling ribs 24 of the present invention. The present invention is not intended to be limited to the specific pallet 10 shown 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.
