Abstract
A pallet has a plastic pallet deck or other pallet plastic surface component including an anti-skid surface, which may be, for example, embossed, applied as a sheet during an extrusion process, applied by calendaring or applied with adhesive.
Description
- The present application claims priority to U.S. Provisional patent application Ser. No. 60/655,793, filed Feb. 23, 2005, and and is a continuation-in part of U.S. patent application Ser. No. 10/729,615, filed Dec. 5, 2003, which is a divisional of U.S. patent application Ser. No. 09/938,954, filed Aug. 24, 2001, which claimed priority to U.S. Provisional patent application Ser. No. 60/227,537, filed Aug. 24, 2000, the entire contents of each of which are specifically incorporated herein by reference.
- The present disclosure relates to pallets including plastic surface components, particularly pallets used for transporting miscellaneous industrial and commercial goods by means of forklift devices and the like.
- It is a problem that plastic pallets have plastic decks or other plastic surfaces that tend to have low friction coefficients and are slippery, as compared to decks of wood pallets, especially when the environment is cold. Thus, objects put on the deck will be more prone to slide off the deck during movement of the pallet.
- It is also undesirable to have to secure the load to the pallet. Providing the deck surface with raised features such as projections, or otherwise texturing the deck, might be effective but they tend to wear and can make cleaning the deck difficult. There is room in the art for improvement with regard to decks and other plastic surface components that have low friction coefficients and are slippery.
- The above described and other problems in the art are overcome or alleviated by the present plastic pallet deck or other pallet plastic surface component having a non-skid surface. In one exemplary embodiment, a plastic pallet deck or other pallet plastic surface component includes a non-skid surface embossed or calendared directly thereon.
- In another exemplary embodiment, a plastic pallet deck or other pallet plastic surface component includes a non-skid film or layer attached thereto.
- In another exemplary embodiment, a plastic pallet deck or other pallet plastic surface component includes spaced apart pieces of material having a higher coefficient of friction than the plastic, such as Santoprene material. The frictional material may comprise strips or may be continuous across the surface.
- In another exemplary embodiment, where the plastic pallet deck or other pallet plastic surface component is extruded as a sheet and attached to a base, the antifriction material is applied as a sheet at the exit of the plastic extruder. In another exemplary embodiment, the antifriction sheet is applied during a calendaring process.
- In another exemplary embodiment, the pallet plastic surface component is a plastic leader board of a slatted wood pallet, which plastic leader board includes a non-skid surface.
- The foregoing and other objects, features and advantages of the present pallet will become more apparent from the following description of exemplary embodiments and accompanying drawings.
- Referring now to the accompanying FIGURES, which are meant to be exemplary and not limiting:
-
FIG. 1 is a perspective view of an exemplary deck including an non-skid surface; -
FIG. 2 is a perspective view of an exemplary deck including strips of non-skid surface material; -
FIG. 3 is a side elevation view of an exemplary deck, mounted on a base and including an embedded non-skid surface; -
FIG. 4 is a perspective view of an exemplary pallet including a frame surface portion with a non-skid surface; and -
FIG. 5 is a top elevation view of a wooden pallet with non-skid plastic leader boards. - Referring now to
FIG. 1 , an exemplary embodiment of a plastic upper deck is shown generally at 112.Upper deck 112 includes a skeletal sub-structure defined byribs 113 andcross beams 115 arranged and supported by each other, as is shown.Ribs 113 are spaced parallel to each other and are traversed bycross beams 115 in a grid pattern arrangement. Anintegument 117 comprising a thin, puncture resistant film is disposed over at least one surface of the skeletal sub-structure ofupper deck 112 and is fused toribs 113 andcross beams 115 to provide a surface upon which objects can be loaded.Integument 117 is configured and dimensioned to prevent or at least minimize the probability of penetration of the surfaces ofupper deck 112 by sharp objects.Integument 117 may include anon-skid surface 17 embossed or calendared directly thereon, or it may include a non-skid film or layer attached thereto. The total non-skid surface coverage ofupper deck 112 can be up to and in excess of about 30% of strategically located non-skid material. In another exemplary embodiment, non-skid coverage is between about 85% and 100%. In another exemplary embodiment, non-skid coverage is about 100%. - Referring now to
FIG. 2 , anexemplary pallet 20 includes a moldedthermoplastic base 24, comprisingvertical columns 30 connected byrails 28. The base may be one piece or an assembly.Deck 26, which in one exemplary embodiment is thermoplastic, such as HDPE or PP, is attached to the top of thecolumns 30. The illustrated deck has an essentially planar top surface with a multiplicity of spaced apartstrips 22 of anti-skid material, such as the product Santoprene (Product No. 20164, General Purpose Elastomer Systems, Akron, Ohio). In an alternate exemplary embodiment, the whole deck top may be surfaced with Santoprene material or the like. In an exemplary embodiment, anti-skid material is a sheet, which may may be applied in various ways, including by adhesives. - In another exemplary embodiment, the
deck 26 is extruded as a thick sheet and the anti-skid material, e.g., Santoprene, is adhered to the sheet so that it is integral. In one mode, the deck is fitted with the anti-skid material at the extruder die exit. Anti-skid material in pellet or semi-molten form is fed into a particularly constructed die, so that it is integrally molded into and formed with the thermoplastic deck sheet during the extrusion process. - Alternately, the thermoplastic is extruded as a sheet from the extruder in conventional manner, and runs to a calendaring machine. Anti-skid material may be provided as a previously formed strip, on a multiplicity of rolls, according to how many strips the maker desires to have on the deck surface. The anti-skid strip is drawn from the roll is laid onto the just-formed and still-hot thermoplastic sheet. Then, the two run together through the rolls of a calendaring machine. The anti-skid strip is pressed into the sheet, to become integral with it.
- Referring now to
FIG. 3 , an exemplary embodiment illustrates anti-skid material that is embedded in thedeck 26. In such embodiments, without limitation, anti-skid material may be deposited, adhered, molded, etc. in depressions in the deck (or indeed, in any surface component of the pallet). Also, in such embodiment, applied strips ofanti-skid material 22 are less prone to coming loose during use. Without being limiting, anexemplary deck 26 installed on a pallet has a thickness t1 of about 70 mils and the anti-skid layer thickness t2 is about 10 mils. Without being limited, other materials may be used as anti-skid materials, for instance rubbery elastomers and other known materials which will adhere to plastics such as polyethylene, polypropylene, etc., with or without the use of adhesive layers. - Referring now to
FIG. 4 , anexemplary pallet 20 includes adeck 26 secured to anupper frame portion 32. The exemplaryupper frame portion 32 is connected torails 28 bycolumns 30. Thedeck 26 may be metal, plastic or any other material, and may be recessed within, bolted onto, overmolded within, etc., theupper frame portion 32. The plastic frame is illustrated as including anon-skid surface 17, which may be in any form described above, including strip orfilm material 22. - Referring now to
FIG. 5 , anexemplary pallet 40 includeswooden stringers 42 andslats 44, as well asplastic leader boards 46.Slats 44 andleader boards 46 are illustrated as bolted tostringers 42 withfasteners 48. Theplastic leader boards 46 is illustrated as including anon-skid surface 17, which may be in any form described above, including strip orfilm material 22. - Although this invention has been shown and described with respect to a exemplary embodiments, it will be understood by those skilled in this art that various changes in form and detail thereof may be made without departing from the spirit and scope of the claimed invention.
