Abstract

A pallet and method of use are provided for carry large quantities of materials for shipping. The pallet is configured to be divided into smaller sub-pallets, such that the pallet can be broken down, or otherwise subdivided, into smaller, more usable sub-pallets containing job lot quantities. Each sub-pallet may comprise decking and one or more skid blocks attached underneath the decking. Stringer boards may be attached to each of the sub-pallets to hold the sub-pallets relatively together. These stringer boards may be removable from each of the sub-pallets so that each of the sub-pallets can be separated from one another.

Previously, in order to complete a home with trim, only traditional materials such as wood and vinyl were available. Recently, James Hardie Building Products has worked on introducing a fiber cement trim to complete a house with a full-wrap of fiber cement warranted exterior products. Such materials include Hardiplank® lap siding, Hardishingle™ siding, Hardipanel® vertical siding, Hardisoffit® soffit panels, and Harditrim® trim planks.
  • In most residential housing building sites, materials are delivered to the site in predetermined quantities for each specific house or development stage. The main medium for transporting siding, trim, fascia, soffit, etc. is by way of pallets, more specifically wooden pallets. When exterior products are manufactured, they are typically fastened to and transported in large quantities on pallets. Because the products are typically shipped in large quantities on large pallets, it is the job of the distributor to break down the materials into manageable sizes requested by the contractors.
  • For example, when trim planks, such as Harditrim® XLD® trim planks, are manufactured, the amount of trim stacked onto a pallet is often enough to finish off approximately 8-10 houses. This is done for economic reasons to the manufacturer; however, it also creates work for the distributor to take the pallet apart and supply the contractor with the required footage. The distributor then, typically, throws the trim on top of pallets that may carry other materials, such as siding. Because these other materials, such as siding, may have greater flexibility than the trim, the siding may tend to sag toward their ends underneath the trim. The more rigid trim is usually bound together with the siding using straps or other means. As the underlying siding provides little support for the trim, once the materials are bound some of the trim may flex and break during transportation. What is needed is a way to ship small (job lot) quantities of trim planks such as Harditrim® XLD® trim planks, and other building products, to construction sites without causing damage to the product.
  • SUMMARY OF THE INVENTION
  • One way to ameliorate some of the above-mentioned disadvantages is to provide a pallet configured to carry large quantities of materials for shipping, which is further configured to be divided into smaller sub-pallets. Accordingly, one embodiment of the present invention is a manufactured pallet that can be broken down, or otherwise subdivided, into smaller, more usable sub-pallets containing job lot quantities. Another embodiment of the present invention is directed to a method of separating a larger manufactured pallet into smaller, more usable sub-pallets for particular jobs.
  • Another embodiment of the invention is directed to a method of easily separating the sub-pallets.
  • In one embodiment, a pallet is provided comprising a plurality of sub-pallets. Each sub-pallet comprises decking and one or more skid blocks attached underneath the decking. One or more stringer boards is attached to each of the sub-pallets, holding the sub-pallets relatively together. The one or more stringer boards are removable from across the skid blocks of each of the sub-pallets so that each of the sub-pallets can be separated from one another.
  • Preferably, the decking comprises a plurality of decking boards. Stringer boards may be provided at either end of the decking and in some embodiments, are provided at both ends of the decking. Additional stringer boards may also be provided between the ends of the decking. A plurality of skid blocks may be attached underneath the decking. In one embodiment, the stringer boards are attached to each of the sub-pallets using smooth pallet nails.
  • In another embodiment, a method of transporting material is provided. A pallet is provided supporting said material. The pallet includes a plurality of sub-pallets attached by stringer boards, each of the sub-pallets supporting a portion of the material. The stringer boards are removed from the sub-pallets, and each of the sub-pallets is separated from one another. Each sub-pallet can then be individually transported for a particular desired use.
  • Preferably, removing the stringer boards comprises removing smooth shank nails connecting the stringer boards across each of the sub-pallets. Each of the sub-pallets may include decking and skid blocks underneath the decking. In one embodiment, each of the sub-pallets supports trim material. The method may further comprise banding together the portion of the material on each of the sub-pallets.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • One embodiment of the present invention is a pallet, preferably made from wood, that is able to be broken down into 3 smaller job lot pallets for delivery to construction sites from the distributor without causing damage to the building product being delivered. In one embodiment, the pallet is adapted for delivery of trim. It will be appreciated that the pallet can be broken down into a fewer or a greater smaller job lot pallets, as desired. It will also be appreciated that any viable pallet material can be used, including, but not limited to, wood, plastic, metal, plastic or wood composite and any combination thereof. Of course, different components of the pallets can each be manufactured of different materials, if desired.
  • FIGS. 1A and 1B illustrate a break-down pallet 100 according to one embodiment of the present invention. The pallet 100 includes skid blocks 110, decking 120, and stringer boards 130. The decking 120 preferably comprises a plurality of elongated boards, more preferably 12 boards provided side by side in parallel relationship with each other. In one embodiment, each of the decking boards is 1″×4″×10′ in dimension. In another embodiment, the decking boards can have varying widths, for example, between about 2″ and 12″, more preferably between about 3″ and 4″, more particularly, 3″ or 3½″. The decking can be longer or shorter, for example, between about 6′ and 12′, or can be even longer or shorter, to accommodate different sized building materials. For example, the decking can be as short as about 2′ to capture smaller items such as boxes. Further details are described below.
  • In one preferred embodiment, the decking boards are preferably divided into three sets having four decking boards 120 each. Each set of decking boards 120 preferably makes up a sub-pallet 140, 150 and 160. The decking boards 120 of each sub-pallet can be spaced from each other, or can be placed flush against each other. Each of the sub-pallets can also be spaced from each other, or can be flush against each other. The skid blocks 110 preferably comprise a plurality of elongated boards, gluts, peeler cores or round timbers, or similar structure (such terms being used interchangeably herein), arranged in generally transverse relationship with the decking boards 120. As illustrated in the embodiment of FIGS. 1A and 1B, each set of decking boards 120 has five skid blocks 110 attached to an underside of the decking boards 120, with two adjacent the ends and three in between. Fewer or greater numbers of skid blocks 110 may be used depending on the length or size of the material being shipped. Standard pallet nails may be used to attach the decking 120 to the skid blocks 110, although it will be appreciated that other fasteners, such as screws, may be used. Accordingly, in this embodiment, 15 total skid blocks 110 are provided. In one embodiment, each of the skid blocks is 4″×4″×14″ in dimension. The skid blocks 110 may be of any appropriate dimension suitable for use with a desired number and size of decking 120.
  • In the illustrated embodiment, a stringer board 130 is preferably attached to the skid blocks 110 at each end of the decking, as shown in FIGS. 1A and 1B. In one embodiment, the stringer boards 130 are 2″×4″×47″ in dimension. The stringer board 130 is preferably attached to the three skid blocks at each end of the decking, preferably using six smooth shank pallet nails across the skid blocks.
  • In one embodiment, each sub-pallet is adapted to support 30 to 60 pieces of 4″ trim, with each sub-pallet holding four pieces of trim across its width, and stacked 15 pieces high. Thus, the whole pallet assembly may hold 12 pieces of trim across and 15 pieces of trim high.
  • FIGS. 2A-2C illustrate another embodiment of a pallet capable of being broken down into sub-pallets. As with the embodiment of FIGS. 1A-1B, the pallet 200 comprises 12 decking boards 220 forming three sets or sub-pallets 240, 250 and 260, with each set being attached by separate skid blocks 210. The decking boards of this embodiment can each have the same width. Alternatively, in one preferred embodiment, in each sub-pallet the two center decking boards are 3½″ wide and the two decking boards on each side are 3″ wide. The decking boards can be flush with each other or have a gap, preferably up to about ¼″. Each of the sub-pallets may be spaced apart by between about ¼″ and 1½″, more preferably by between about ½″ and 1¼″, and even more preferably by about 1″.
  • As shown in the side view of FIG. 2B, four skid blocks (here in the form of round timbers 210) are provided along the length of the decking boards 220, each skid block 210 provided generally transverse to the length of the decking boards 220 and attached along an undersurface of four decking boards. Stringer boards 230 are provided adjacent each of the skid blocks 210, the stringer boards 230 extending generally transversely across an undersurface of all twelve of the decking boards 220. As illustrated, two stringer boards 230 are provided at the ends of the decking boards, with two additional stringer boards 230 provided between the two outer stringer boards, preferably 42″ from the outer stringer boards. Alternatively, the stringer boards 230 and timbers 210 can be equally spaced from each other. Thus, in this embodiment, four stringer boards 230 are attached to reinforce the pallet during shipment, and accordingly, when the pallet is broken down, all four stringers 230 should be removed. Preferably, the stringer boards 230 and the skid blocks 210 provided at the ends of the decking boards are located right at or near the ends of the decking boards, for example, no more than about 6″ from each of the ends. It will be appreciated that although FIG. 2B illustrates the skid blocks located to the inside of the stringer boards, they can also be provided to the outside of the stringer boards.
  • As illustrated in the embodiment shown in FIGS. 2A-2B, when connected together the whole pallet is 42″ by 120″ in dimension, with each skid block (and consequently each sub-pallet) being 14″ long (or wide). The stringer boards 230 of this embodiment may therefore be 42″ in length. Alternatively, the stringer boards may be longer or shorter, for example, between about 36″ and 48″. It will be appreciated that the whole pallet and each of the sub-pallets can have any suitable dimension for transporting material, and that the number of sub-pallets can differ from three. Therefore, in alternate embodiments, two, four, five, six, seven, eight or more sub-pallets can be used. The number or length of the skid blocks may also vary. The length, for example, can be between about 8″ and 24″, more preferably between about 12″ and 16″. It will also be appreciated that for any given assembly of sub-pallets, each of the sub-pallets need not have the same dimension, so that some sub-pallets are wider than others. Additionally, the sub-pallets need not all be attached parallel along a longitudinal edge. For example, a substantially square pallet can be comprised of four smaller square sub-pallets.
  • Referring to the embodiment of FIGS. 2A-2C, FIG. 3 illustrates one method of separating a pallet into sub-pack pallets, including the steps of:
  • Step 310: Removing the Stringers
  • In this step, after the banding is removed from around the pallet and the material on the pallet, the four stringers are completely removed from the sides of the round timbers. This can be done by using a hammer or pry-bar or any other means suitable for prying. Nailing is minimal on the stringers (with roughly 6-10 smooth shank nails across each stringer), so removal is preferably easily accomplished by a person, without requiring substantial mechanical force or assistance. Thus, nails or other suitable fasteners should be used that are sufficient to hold the stringers against the timbers during transport, but allow for removal of the fasteners without excessive force. The pallet is preferably elevated during this stage (preferably by at least 12 inches) using a forklift or pallet jack.
  • Step 320: Break Into Mini Pallets
  • In this step, after the stringers are removed, the pallet is set down on a flat surface. The forklift driver then reverses out until only about 12″ of the forks remain under the pallet. Then the first mini or sub-pallet is elevated slightly (preferably about 3-4 inches) and moved away from the other two sub-pallets. This step can be repeated for the second mini or sub-pallet.
  • Step 330: Reband Mini Pallets
  • In this step, the trim on the mini or sub-pallets are rebanded, preferably using corner protectors on the trim. Banding, which may include metal or plastic straps or other suitable means, is preferably at least put around each of the sub-pack pallet ends and one in the center.
  • Alternatively, the job lot quantities of trim can be primarily banded to each sub-pallet by the manufacturer, thus creating job lot quantities already banded to a sub-pallet. The banded job lot quantities can be secondarily banded together on the assembled sub-pallets. When banded this way by the manufacturer, the distributor need only remove the stringers and the secondary banding, thus leaving the job lot quantities banded to the sub-pallets ready for delivery to work sites.
  • Advantageously, the preferred embodiments described above provide a way to safely ship job-lot packs to the construction site without damaging the product. These embodiments also provide a way to have a more convenient means of logistically gathering an order for the builder/contractor from the distributor. Furthermore, these embodiments provide a way to possibly capture more smaller/stocking dealers on the basis they would have less risk of large quantities in inventory and better pricing.
  • The pallet described above, while being applicable for fiber cement trim product, can be used for any type of product whether it is building products (e.g., cladding), landscaping materials (e.g., retaining walls), or materials that are shipped in boxes. Any material or product that is broken down at the distributor from the manufacturer for further distribution in bundles can use this design.
  • Although the foregoing invention has been described in terms of certain preferred embodiments, other embodiments will become apparent to those of ordinary skill in the art, in view of the disclosure herein. Accordingly, the present invention is not intended to be limited by the recitation of preferred embodiments.
