Definitions

  • the field of the invention relates generally to pallets and, more particularly, to multi-component pallets that may be disassembled and whose components may be nested with each other to ' reduce the pallet's volume while in the disassembled state.
  • Pallets have been widely utilized in environments such as warehouses, factories and the shipping industry to provide a portable platform for handling, storing and moving materials.
  • pallets have been made of wood, which has proven to be an effective construction material.
  • a typical wooden pallet includes multiple spaced slats mounted to the top surface of spaced transverse stringers which elevate the top slats from the ground and allow handling of the pallet with equipment, such as a forklift. The top slats can then provide a surface to support a load. In some cases, additional spaced slats
  • Spacing the slats can allow for a reduction in the overall weight of the pallet while still providing sufficient surface area on the top deck section to support a load. Spacing between the slats also prevents the collection of dirt, trash, water or other debris on the pallet, as such material is able to pass between the slats. While wooden pallets do not allow for a significant amount of flexibility in terms of design characteristics, they can be manufactured with relatively low costs while providing adequate strength for a variety of applications. [004] However, common wood pallets present several deficiencies, particularly when they are used in connection with the international shipment of goods.
  • plastic pallets can provide some advantages over wooden pallets, including the ability to provide a significant amount of flexibility in terms of design characteristics, simplified manufacturing through the use of injection molding techniques, lightweight, and improved strength and durability. Also, in the case of the international shipment of goods, plastic pallets do not have to be treated for insect infestation. Plastic pallets are typically more expensive to manufacture than wood pallets. In addition, many current plastic pallets tend to collect dirt, trash and water over time due to their corrugated structure that does not open up to allow debris to pass through. [007] Typical one-piece plastic pallets can be configured to allow the pallets to be easily nested, or stacked upon each other when they are in the unloaded state.
  • Nesting is typically accomplished by providing recesses in the top deck section of one pallet that are configured to receive the feet positioned on the fork strap section of a second pallet, as the second pallet is stacked onto the first pallet. This process can be repeated to facilitate the stacking and transporting of multiple pallets in the unloaded state, and is desirable because it reduces the overall shipping volume of the unloaded pallets, allowing some cost savings.
  • one-piece nestable pallets have other drawbacks.
  • current nestable pallets typically do not have any openings, which allows dirt and water to collect.
  • Other nestable pallets are often-times not able to be stacked on traditional stringer/slat wood pallets due to their design, which sometimes makes them inconvenient.
  • the invention is related to multi-component pallets that may be disassembled and whose components may be nested.
  • the invention provides a pallet which includes a first deck configured to be connected to a second deck in a first position when the pallet is in the loaded state.
  • the first deck can be configured to be nested with the second deck in a second position when the pallet is in the unloaded state, wherein the volume of the first deck and the second deck in the first position is greater than the volume of the first deck and the second deck in the second position.
  • the invention is related to a multi-component pallet which comprises a fork strap section having a slat member and a first leg core, the first leg core including a first interlocking joint member.
  • the multi-component pallet can also comprise a top deck section having a second slat member and a second leg core, the second leg core including a second interlocking joint member.
  • the second leg core can be configured to form an opening in the top deck section.
  • the opening can be configured to complement the configuration of the first leg core.
  • the top deck section m&y be removably coupled to the fork strap section by slidably engaging the first interlocking joint member of the first leg core with the second interlocking joint member of the second leg core to form a joint.
  • the invention is related to a disassembled multi-component pallet which comprises a fork strap section having a first slat member and a first leg core including a first interlocking joint member.
  • the disassembled multi-component pallet can further comprise a top deck section having a second slat member and a second leg core including a second interlocking joint member.
  • the second leg core can be configured to form an opening in the top deck section when the pallet is configured in a load-bearing state.
  • the opening can also be configured to complement the configuration of the first leg core such that the top deck section may be inverted and placed over the fork strap section to nest the top deck section and the fork strap section to reduce the height of said pallet.
  • the invention is related to a multi-component pallet which comprises a fork strap section, and a top deck section.
  • the fork strap section can include a first means for providing structural support and a first joint means to enable the coupling of the fork strap section to the top deck section.
  • the top deck section can include a second means for providing structural support and a second joint means to enable the coupling of the fork strap section to the top deck section.
  • the multi- component pallet can also comprise a means for preventing movement once the fork strap section has been coupled to the top deck section, wherein the second joint means can be configured to form an opening in the top deck section.
  • the opening can be configured in size and shape to compliment the first joint means, so that when the pallet is disassembled, the top deck section may be inverted and placed over said fork strap section to nest said top deck section and said fork strap section to reduce the height of said pallet.
  • the invention is related to a method for disassembling a multi- component pallet having a top deck section with a plurality of openings and a plurality of leg cores and a fork strap section with a plurality of openings and a plurality of leg cores which comprises the steps of removing the top deck section from the fork strap section, inverting the top deck section and nesting the top deck section with the fork strap section by inserting the plurality of leg cores of the fork strap section into the plurality of
  • the invention is related to a method for transporting an item from a point of origin to a destination with a pallet having a first deck and a second deck which comprises the steps of connecting the top deck section to the fork strap section in a first position, placing an item on the top deck section of the pallet at the point of origin, transporting the pallet and the item to the destination, removing the item from the pallet at the destination, removing the top deck section from the fork strap section, and nesting the top deck section with the fork strap section in a second position, wherein the volume of the top deck section and the fork strap section in the second position is less than the volume of the top deck section and the fork strap section in the first position.

Abstract

Palette multi-composant comprenant un premier plateau et un second plateau. Le premier plateau peut être disposé de manière à être relié libérable au second plateau dans une première position de charge, à l'état assemblé. Ce premier plateau peut également s'emboîter dans le second plateau lorsque la palette est vide, à l'état désassemblé. Le premier et le second plateaux peuvent être placés de sorte que le volume de la palette à l'état assemblé, en position de charge, est supérieur à celui du premier et du second plateau lorsqu'ils sont emboîtés l'un dans l'autre à l'état désassemblé, à vide.
