Definitions
- the present disclosure is generally directed to the pallets and portable structures for handling, storing, or transporting materials.
- Traditional pallets are generally made from wood or other similar materials, and the pallet provides a stable, weight-bearing surface for handling, storing, or transporting materials.
- Traditional pallets can weigh between 33-40 pounds and can be difficult to handle.
- a falling pallet or the failure of a pallet can result in injury due to the heavy weight of a traditional pallet.
- Methods, devices, and systems for assembling a pallet are provided.
- multiple pieces can be bent and selectively connected with each other without the use of fasteners or adhesives to form the pallet.
- the pieces can be made from cardboard to significantly reduce the weight of the pallet.
- a pallet can comprise at least one longitudinal piece that is bent into a final shape and then locked in a final shape with a transverse piece.
- the longitudinal piece can have an initial shape that is substantially planar, and bend lines on the longitudinal piece indicate where the longitudinal piece can be bent to form the final shape.
- the bend lines can also define which portions of the longitudinal piece are horizontal portions in the final shape, are vertical portions in the final shape, or any other orientation in the final shape.
- the horizontal portions define the horizontal extent of the pallet, and as described in further detail below, the horizontal portions can at least partially define the fork apertures of the pallet.
- the vertical portions define the vertical extent of the pallet, which is the smallest dimension of the pallet.
- the vertical portions are substantially perpendicular to the top surface of the pallet that receives the materials, loads, etc. to be transported using the pallet. Therefore, the force from the materials, loads, etc. extends through a planar direction of the vertical portions, and the planar direction of the vertical portions is the strongest with respect to compressive forces.
- a transverse piece selectively connects to the at least one longitudinal piece to lock the longitudinal piece in the final shape and to lock the horizontal and vertical portions in the horizontal and vertical directions, respectively.
- transverse slots extend across the longitudinal piece in a direction that is perpendicular to the bend lines.
- the transverse slots extend into the longitudinal piece in a direction that is substantially parallel to the bend lines.
- the transverse piece engages these transverse slots, and the transverse piece can have at least a portion that is substantially perpendicular to both the horizontal portion and the vertical portion of the longitudinal piece.
- the transverse piece may have a series of recesses on the portions of the transverse piece that selectively connect to the longitudinal piece and engage the transverse slots.
- the recesses generally correspond to the vertical portions and/or the horizontal portions of the longitudinal piece to provide a more complete and secure selective connection with the longitudinal piece.
- the orientation of the transverse slots and the transverse piece contributes to the ability of the transverse piece to lock the longitudinal piece in the final shape.
- a pallet can comprise pieces that are joined together in an interference fit without the use of separate fasteners or adhesives. As the pieces are bent from an initial shape to a final shape, the pieces have a tendency to unfurl or revert back to the initial shape. This aspect of the pieces is utilized to lock the pieces together in an interference fit.
- An exemplary longitudinal piece has several bend lines that are substantially parallel to each other. Therefore, when the longitudinal piece is bent into a final shape, the longitudinal piece has a tendency to unfurl in a single direction.
- a transverse piece can have a series of recesses that receive the vertical portions and/or horizontal portions of the longitudinal piece, and the tendency of the longitudinal piece to unfurl causes the vertical and horizontal portions to press against the transverse piece within a given recess to lock the transverse piece and the longitudinal piece together.
- the transverse piece may also have bend lines, an initial shape, a final shape, and a tendency to unfurl from the final shape to the initial shape.
- the tendency to unfurl causes the transverse piece to press against the longitudinal piece within the transverse slot to lock the transverse piece and the longitudinal piece together.
- a pallet can comprise multiple pieces to enhance the performance of the pallet and increase the compressive strength of the pallet.
- the vertical portions can provide the requisite compressive strength of the pallet.
- Additional longitudinal pieces can be added to the original longitudinal piece so that vertical portions from multiple pieces can reinforce each other and/or distribute loads from an upper surface of the pallet across more vertical portions.
- horizontal portions from multiple pieces can reinforce each other and/or distribute loads from various directions.
- a pallet can comprise a planar piece that provides an upper surface of the pallet to receive materials. It may be advantageous to have a continuous upper surface of the pallet to distribute loads to the other pieces of the pallet and to provide a surface that can contain disparate parts on a common surface. For instance, a planar piece can receive aggregate materials such as gravel on a common surface rather than have individual pieces of gravel slip through the pallet onto the ground. Similar to other pieces described herein, a planar piece can have bend lines, and the planar piece can be bent from an initial shape to a final shape.
- the longitudinal pieces can have planar slots that are configured to receive ends of the planar piece. Like the transverse piece, the planar piece can have recesses that correspond to vertical portions and/or horizontal portions of the longitudinal pieces to better selectively connect the planar piece and the longitudinal pieces.
- a pallet can comprise a plurality of fork apertures to receive the forks of a forklift.
- Pallets have recesses or apertures that receive the forks of a forklift so that the forklift can maneuver the pallet and transport the load on the pallet.
- fork slots in the various pieces can at least partially define a fork aperture in the pallet.
- the various portions of the pieces themselves, such as the horizontal and vertical portion of the longitudinal pieces can define a fork aperture in the pallet.
- These fork apertures are generally arranged with a first and second fork aperture oriented parallel to each other and extending through the pallet and with a third and fourth fork aperture oriented parallel to each other and extending through the pallet.
- the first and second fork apertures may intersect the third and fourth fork apertures.
- a pallet can comprise components made from cardboard such as a corrugated fiberboard that has a fluted corrugated sheet and a linerboard.
- Corrugated fiberboard can be characterized in a number of ways, for example, the fiberboard and/or liner board may be made from paper using the kraft process.
- the fluted corrugated sheet may have different flute sizes and pitches graded from A to F where a B flute has 47+/ ⁇ 3 flutes per linear foot and a flute thickness of 1 ⁇ 8 inch, and a C flute has 39+/ ⁇ 3 flutes per linear foot and a flute thickness of 5/32 inch.
- a BC flute is a double-walled corrugated board where three liner boards provide space for two fluted corrugated sheets, where one fluted corrugated sheet has a B flute and the other fluted corrugated sheet has a C flute.
- an edge crush test determines the strength of a piece of cardboard, and in this test, the edges of a piece of cardboard are placed between two plates and then subjected to a compressive force. A peak force is identified in pounds/inch. Therefore, an exemplary piece of cardboard may be identified as kraft flute BC ECT 42 fiberboard. This piece has components made from the kraft process, has a double-wall design with a B flute and a C flute, and has an edge crush test value of 42 pounds/inch. It will be appreciated that the embodiments described in this disclosure can utilize this type of cardboard, other types of cardboard, or any other material that can be used in accordance with the description herein.

Since the fourth transverse piece 224 is symmetric about a midline the transverse piece 224 has two fork slots 248 f in total. Next, the fourth transverse piece 224 has a series of recesses 260 f .
- These recesses 260 f generally correspond to vertical portions of the longitudinal pieces. This allows the fourth transverse piece 224 to extend completely downward into the transverse slots of the longitudinal pieces so that the top of the fourth transverse piece 224 is flush or substantially flush with the tops of the longitudinal pieces. Referring to FIG. 14B , the fourth transverse piece 224 is folded about the bend lines.

Abstract
Methods, devices, and systems for assembling a pallet are provided. In particular, a pallet is provided that is made from multiple pieces that are bent from an initial planar shape to a final shape. In some embodiments, a transverse piece locks at least one longitudinal piece in the final shape without the use of fasteners or adhesives. The resulting pallet can be loaded with materials and then maneuvered and transported using a forklift. In addition, the pieces can be made from cardboard which significantly reduces the weight of the pallet.
Description
- The present application claims the benefits of and priority, under 35 U.S.C. § 119(e), to U.S. Provisional Application No. 62/597,162 filed Dec. 11, 2017 by Alfonso Dominguez Guevara and entitled “Cardboard Pallet”, and the present application claims the benefits of and priority, under 35 U.S.C. § 119(e), to U.S. Provisional Application No. 62/608,033 filed Dec. 20, 2017 by Alfonso Dominguez Guevara and entitled “Cardboard Pallet”, of which the entire disclosures are incorporated herein by reference for all purposes.
- The present disclosure is generally directed to the pallets and portable structures for handling, storing, or transporting materials.
- Traditional pallets are generally made from wood or other similar materials, and the pallet provides a stable, weight-bearing surface for handling, storing, or transporting materials. However, there are several shortcomings with traditional pallets. Traditional pallets can weigh between 33-40 pounds and can be difficult to handle. Furthermore, a falling pallet or the failure of a pallet can result in injury due to the heavy weight of a traditional pallet.
- The material construction of traditional pallets presents additional issues. For example, wooden packaging materials, such as pallets, require fumigation to prevent pests from traveling with the pallets as the pallets are shipped around the world. Fumigation treatments can include debarking, heat treatment, and/or methyl bromide treatment. These treatments increase costs and can pose environmental issues depending on the type of treatment. Traditional pallets are typically made from wood and other materials such as metal fasteners, which can make the pallet more difficult to recycle due to the need for disassembly or shredding.
- Methods, devices, and systems for assembling a pallet are provided. In particular, multiple pieces can be bent and selectively connected with each other without the use of fasteners or adhesives to form the pallet. In addition, the pieces can be made from cardboard to significantly reduce the weight of the pallet. These aspects of the various exemplary embodiments and other aspects described herein address the above issues with traditional pallets.
- According to one embodiment, a pallet can comprise at least one longitudinal piece that is bent into a final shape and then locked in a final shape with a transverse piece. The longitudinal piece can have an initial shape that is substantially planar, and bend lines on the longitudinal piece indicate where the longitudinal piece can be bent to form the final shape. The bend lines can also define which portions of the longitudinal piece are horizontal portions in the final shape, are vertical portions in the final shape, or any other orientation in the final shape. Generally, the horizontal portions define the horizontal extent of the pallet, and as described in further detail below, the horizontal portions can at least partially define the fork apertures of the pallet. The vertical portions define the vertical extent of the pallet, which is the smallest dimension of the pallet. Therefore, stated another way, the vertical portions are substantially perpendicular to the top surface of the pallet that receives the materials, loads, etc. to be transported using the pallet. Therefore, the force from the materials, loads, etc. extends through a planar direction of the vertical portions, and the planar direction of the vertical portions is the strongest with respect to compressive forces.
- A transverse piece selectively connects to the at least one longitudinal piece to lock the longitudinal piece in the final shape and to lock the horizontal and vertical portions in the horizontal and vertical directions, respectively. In some embodiments, transverse slots extend across the longitudinal piece in a direction that is perpendicular to the bend lines. In other embodiments, the transverse slots extend into the longitudinal piece in a direction that is substantially parallel to the bend lines. In either instance, the transverse piece engages these transverse slots, and the transverse piece can have at least a portion that is substantially perpendicular to both the horizontal portion and the vertical portion of the longitudinal piece. In addition, the transverse piece may have a series of recesses on the portions of the transverse piece that selectively connect to the longitudinal piece and engage the transverse slots. The recesses generally correspond to the vertical portions and/or the horizontal portions of the longitudinal piece to provide a more complete and secure selective connection with the longitudinal piece. The orientation of the transverse slots and the transverse piece contributes to the ability of the transverse piece to lock the longitudinal piece in the final shape.
- According to one embodiment, a pallet can comprise pieces that are joined together in an interference fit without the use of separate fasteners or adhesives. As the pieces are bent from an initial shape to a final shape, the pieces have a tendency to unfurl or revert back to the initial shape. This aspect of the pieces is utilized to lock the pieces together in an interference fit. An exemplary longitudinal piece has several bend lines that are substantially parallel to each other. Therefore, when the longitudinal piece is bent into a final shape, the longitudinal piece has a tendency to unfurl in a single direction. A transverse piece can have a series of recesses that receive the vertical portions and/or horizontal portions of the longitudinal piece, and the tendency of the longitudinal piece to unfurl causes the vertical and horizontal portions to press against the transverse piece within a given recess to lock the transverse piece and the longitudinal piece together.
- A similar aspect of the transverse piece is utilized to enhance the interference fit between pieces. The transverse piece may also have bend lines, an initial shape, a final shape, and a tendency to unfurl from the final shape to the initial shape. When the transverse piece is positioned within the transverse slots of the longitudinal piece, the tendency to unfurl causes the transverse piece to press against the longitudinal piece within the transverse slot to lock the transverse piece and the longitudinal piece together.
- According to one embodiment, a pallet can comprise multiple pieces to enhance the performance of the pallet and increase the compressive strength of the pallet. As described above, the vertical portions can provide the requisite compressive strength of the pallet. Additional longitudinal pieces (second longitudinal pieces, third longitudinal pieces, etc.) can be added to the original longitudinal piece so that vertical portions from multiple pieces can reinforce each other and/or distribute loads from an upper surface of the pallet across more vertical portions. Similarly, horizontal portions from multiple pieces can reinforce each other and/or distribute loads from various directions.
- According to one embodiment, a pallet can comprise a planar piece that provides an upper surface of the pallet to receive materials. It may be advantageous to have a continuous upper surface of the pallet to distribute loads to the other pieces of the pallet and to provide a surface that can contain disparate parts on a common surface. For instance, a planar piece can receive aggregate materials such as gravel on a common surface rather than have individual pieces of gravel slip through the pallet onto the ground. Similar to other pieces described herein, a planar piece can have bend lines, and the planar piece can be bent from an initial shape to a final shape. The longitudinal pieces can have planar slots that are configured to receive ends of the planar piece. Like the transverse piece, the planar piece can have recesses that correspond to vertical portions and/or horizontal portions of the longitudinal pieces to better selectively connect the planar piece and the longitudinal pieces.
- According to one embodiment, a pallet can comprise a plurality of fork apertures to receive the forks of a forklift. Pallets have recesses or apertures that receive the forks of a forklift so that the forklift can maneuver the pallet and transport the load on the pallet. In embodiments of the present disclosure, fork slots in the various pieces can at least partially define a fork aperture in the pallet. In addition or in the alternative, the various portions of the pieces themselves, such as the horizontal and vertical portion of the longitudinal pieces, can define a fork aperture in the pallet. These fork apertures are generally arranged with a first and second fork aperture oriented parallel to each other and extending through the pallet and with a third and fourth fork aperture oriented parallel to each other and extending through the pallet. As a result, a forklift with two parallel forks can engage the pallet from four different sides. The first and second fork apertures may intersect the third and fourth fork apertures.
- According to one embodiment, a pallet can comprise components made from cardboard such as a corrugated fiberboard that has a fluted corrugated sheet and a linerboard. Corrugated fiberboard can be characterized in a number of ways, for example, the fiberboard and/or liner board may be made from paper using the kraft process. Further, the fluted corrugated sheet may have different flute sizes and pitches graded from A to F where a B flute has 47+/−3 flutes per linear foot and a flute thickness of ⅛ inch, and a C flute has 39+/−3 flutes per linear foot and a flute thickness of 5/32 inch. A BC flute is a double-walled corrugated board where three liner boards provide space for two fluted corrugated sheets, where one fluted corrugated sheet has a B flute and the other fluted corrugated sheet has a C flute. Next, an edge crush test determines the strength of a piece of cardboard, and in this test, the edges of a piece of cardboard are placed between two plates and then subjected to a compressive force. A peak force is identified in pounds/inch. Therefore, an exemplary piece of cardboard may be identified as kraft flute BC ECT 42 fiberboard. This piece has components made from the kraft process, has a double-wall design with a B flute and a C flute, and has an edge crush test value of 42 pounds/inch. It will be appreciated that the embodiments described in this disclosure can utilize this type of cardboard, other types of cardboard, or any other material that can be used in accordance with the description herein.

There is onefork slot 140 d on a right half of thepiece 116 and since thetransverse piece 116 is symmetric about a midline, thetransverse piece 116 has twofork slots 140 d in total. Next, thetransverse piece 116 has a series ofrecesses 152 d. Theserecesses 152 d generally correspond to vertical portions of the longitudinal pieces. This allows thetransverse pieces 116 to extend completely downward into the transverse slots of the longitudinal pieces so that the tops of thetransverse pieces 116 are flush or substantially flush with the tops of the longitudinal pieces. In addition, therecesses 152 d help resist the tendency of the longitudinal pieces to unfurl and provide an interference fit between thetransverse pieces 116 and the longitudinal pieces. Referring toFIG. 5B , thetransverse piece 116 is folded about the bend line. Like the longitudinal pieces, thetransverse piece 116 also generally has some bias back towards the initial position. This aspect helps lock thetransverse piece 116 into the transverse slots in an interference fit. -
