[0001] This invention relates to a pallet size extension member for supporting goods that protrude from the goods placement surface of a pallet.

Background Art

[0002] When loading goods on a pallet for transportation, if a cargo with a bottom surface larger than the cargo placement surface of the pallet is placed, and the cargo is flexible, there is a risk of deformation in the part of the cargo that protrudes from the pallet. To prevent such a phenomenon, a pallet corresponding to the size of the cargo may be used, but there are cases where a pallet of the appropriate size cannot be prepared.

[0003] As a countermeasure, in Patent Document 1 below, a pallet size extension member E2 as shown in FIG. 7 is proposed. This pallet size extension member E2 is detachably attached to the upper part of the pallet 60, and has a configuration in which square column-shaped support bars 52 are fixed to the lower surfaces of both ends of a top plate 51 having an area larger than the cargo placement surface of the pallet 60. The material of the pallet size extension member E2 is preferably cardboard or wood.

[0004] The pallet 60 is formed by arranging a plurality of elongated plate-like deck boards 61 that form a rectangular cargo placement surface in parallel with a gap therebetween, and arranging girders 62 at both ends and the center in the length direction so as to intersect the length direction of the deck boards 61, and fixing the deck boards 61 to the upper surfaces of the girders 62.

[0005] When such a pallet size extension member E2 is attached to the upper part of the pallet 60 as shown in FIG. 8, both ends of the top plate 51 protrude from the pallet 60, and the support bars 52 abut against the side surfaces of the girders 62 located at both ends of the pallet 60. Even if goods that protrude from the cargo placement surface of the pallet 60 are placed on the top plate 51, the goods are supported by the ends of the top plate 5 so that they do not bend.

[0006] [Patent Document 1] Japanese Patent Publication No. 2011-126590 [Overview of the project] [Problems that the invention aims to solve]

[0007] However, with the pallet size extension member E2 described above, the top plate 51 is larger than the cargo loading surface of the pallet 60, which results in higher material costs, poor space efficiency during transportation and storage, and difficulties in handling.

[0008] Furthermore, because the size of the top plate 51 cannot be changed, in order to support cargo of different sizes, multiple types of top plates 51 with different sizes must be prepared, which increases the cost required for manufacturing and managing transport materials.

[0009] Therefore, the objective of this invention is to provide a pallet size expansion member at low cost that is easy to handle during transportation and storage and can efficiently accommodate cargo of different sizes. [Means for solving the problem]

[0010] To solve the above problems, the pallet size expansion member according to this invention is made of a sheet material, a bracket portion is attached to one end of the expansion top plate, and the expansion top plate covers only the portion facing one end of the cargo loading surface of the pallet and extends out from that end. The bracket portion is formed by bending inclined support plates, vertical plates, and horizontal plates that are sequentially connected from the extension top plate to form a triangular tube shape. The vertical plate is positioned along the side of the pallet, and the extended top plate is secured to the cargo loading surface of the pallet, thereby attaching and fixing it to the pallet.

[0011] Furthermore, it is made of sheet material, with a bracket attached to one end of the extension top plate, and the extension top plate covers only the portion facing one end of the cargo loading surface of the pallet, and extends out from that end. The bracket portion is a pallet size expansion member in which diagonal support plates, vertical plates, and horizontal plates, which are sequentially connected from the expansion top plate, are bent to form a triangular tube shape. The vertical plate is provided with spacer sections that can be separated via cutting lines. The expanded top plate is attached and fixed to the pallet by engaging with the cargo loading surface of the pallet, either in a fully expanded state where the spacer portion is interposed between the side surface of the pallet and the vertical plate, or in a slightly expanded state where the spacer portion is detached from the vertical plate and the vertical plate is aligned with the side surface of the pallet.

[0012] Furthermore, the extended top plate has notches to form locking pieces, which are pressed into holes in the cargo loading surface of the pallet, thereby securing it to the pallet.

[0013] Furthermore, the bracket portion is connected to both ends and the middle of the edge of the extended top plate.

[0014] Furthermore, the spacer portion is provided one at a time on bracket portions connected to both ends of the edge of the extension top plate, so as to be connected to the inside of the vertical plate, and two at a time on bracket portions connected to the middle of the edge of the extension top plate, so as to be connected to both sides of the vertical plate. [Effects of the Invention]

[0015] The pallet size expansion member according to this invention is designed so that the expansion top plate covers only the portion facing one end of the cargo loading surface of the pallet, and is considerably smaller than the cargo loading surface of the pallet. As a result, it does not take up much space during transport or storage, is easy to handle, and reduces the material costs required for manufacturing, allowing it to be provided at a low cost.

[0016] In addition, since the bracket portion forms a triangular cylindrical body, it has a strong structure and can firmly support the goods protruding from the cargo placement surface of the pallet.

[0017] Furthermore, it can be assembled only by bending and inserting, which can suppress equipment costs, has good workability, and can be manufactured with a small number of man-hours.

[0018] Also, if a separable spacer portion is provided on the vertical plate of the bracket portion, when the protrusion of the goods is small, the spacer portion can be cut off, and when the protrusion of the goods is large, it can be interposed between the vertical plate and the side surface of the pallet without cutting off the spacer portion, so that it can efficiently cope with goods of different sizes.

MODE FOR CARRYING OUT THE INVENTION

[0020] <SUMMARY> The pallet size extension member E1 shown in Figure 1 is made of corrugated cardboard and is used in pairs. Each member is attached to both sides of the resin pallet 40 to support the portion of the cargo that extends beyond the pallet 40.

[0021] The pallet 40 has a rectangular shape in plan view, and the cargo loading surface 41 has numerous ribs arranged in a grid pattern to form holes 42, and insertion openings 43 into which the forks of a forklift are inserted are provided on the side corresponding to the long side of the cargo loading surface 41.

[0022] <blank> As shown in Figure 2, the blank of the pallet size extension member E1 before assembly has a shape in which bracket portions 2 are attached to both ends and the middle of one of the long sides of a rectangular extension top plate 1, and spacer portions 3 are attached to the inside of the bracket portions 2 at both ends and on both sides of the bracket portion 2 in the middle.

[0023] In this blank, the corrugated cardboard is oriented in the direction in which the extended top plate 1 and the bracket portion 2 are connected, and the strength in the corrugated cardboard direction is greater than the strength in other directions, so care has been taken to suppress the bending of the portion of the pallet 40 that protrudes from the cargo loading surface 41.

[0024] The extension top plate 1 is designed to cover only the portion of the cargo loading surface 41 of the pallet 40 that faces the shorter side, and to extend beyond that shorter side. The extension top plate 1 has notches and hinge lines, and is formed with four pairs of locking pieces 11 for fixing to the pallet 40, and three locking pieces 12 for maintaining the assembled shape of the bracket portion 2 and engaging with the extension top plate 1.

[0025] The bracket section 2 consists of an inclined support plate 21, a vertical plate 22, and a horizontal plate 23 that are sequentially connected from the extension top plate 1 via fold lines, and the inclined support plate 21, vertical plate 22, and horizontal plate 23 are bent to form a triangular tube. The vertical plate 22 has a rectangular locking hole 24 facing the boundary with the horizontal plate 23, and the locking hole 24 is slightly cut into the horizontal plate 23.

[0026] The spacer portion 3 connected to the bracket portion 2 at both ends is such that a support plate 31 is detachably connected to the inside of the vertical plate 22 of the bracket portion 2 via a cut line 30, an expanding plate 32 and a support plate 33 are sequentially attached to the support plate 31 via a fold line, an expanding plate 34 and a support plate 35 are sequentially attached to the opposite side via a fold line, and an expanding plate 36 and an insert piece 36a are sequentially attached to the side end of the support plate 35 via a fold line.

[0027] In this spacer portion 3, the support plate 33 has a slit-shaped locking hole 33a formed along the boundary with the expanding plate 32, and a tongue-shaped locking piece 35a is provided protruding from the tip edge of the support plate 35 via a hinge-like fold line.

[0028] The spacer section 3 connected to the intermediate bracket section 2 has support plates 31 detachably connected to both sides of the vertical plate 22 of the bracket section 2 via cut lines 30. Expanding plates 32, 33, and 37 are sequentially attached to the support plate 31 via fold lines, and an expanding plate 34 is attached to the opposite side. Additionally, an expanding plate 38 and an insert piece 38a are sequentially attached to one end of the support plate 33 via fold lines.

[0029] In this spacer portion 3, the expanding plate 37 has a slit-shaped locking hole 37a formed along the boundary with the support plate 33, and a tongue-shaped locking piece 34a is provided protruding from the leading edge of the expanding plate 34 via a hinge-like fold line.

[0030] Furthermore, of the pair of spacer portions 3 connected to the intermediate bracket portion 2, a rectangular locking hole 33b is formed in the support plate 33 of one of the spacer portions 3, facing the boundary with the expanding plate 38, and the locking hole 33b is slightly cut into the expanding plate 38. A locking piece 33c is provided protruding from the support plate 33 of the other spacer portion 3 by a cut into the expanding plate 38.

[0031] <Assembly process from a blank> To assemble the blank of the pallet size extension member E1 as described above, as shown in the inverted state in Figure 3, the bracket portion 2 from the extension top plate 1 is folded into a triangular tube shape so that the extension top plate 1 and the diagonal support plate 21 form an acute angle, the vertical plate 22 is perpendicular to the extension top plate 1, and the horizontal plate 23 overlaps the back surface of the extension top plate 1. Then, the locking piece 12 is pushed into the locking hole 24 to maintain the triangular tube shape of the bracket portion 2.

[0032] (Assembly into the greatly expanded form) Furthermore, when using the spacer section 3 to create a large-expansion configuration that significantly expands the area capable of supporting cargo, each spacer section 3 is assembled into a box shape and bent along the vertical plate 22 of the bracket section 2, with the cut line 30 as the axis.

[0033] At that time, the spacer portion 3 connected to the bracket portion 2 at both ends is formed by bending the expanding plate 32 horizontally from the support plate 31, bending the support plate 33 vertically, bending the expanding plate 34 horizontally, bending the support plate 35 vertically so that it overlaps the support plate 33, and inserting the locking piece 35a into the locking hole 33a.

[0034] Then, by overlapping the support plate 31 and the vertical plate 22, bending the expanding plate 36 to close the end face of the spacer portion 3, and bending the insertion piece 36a to embrace the vertical plate 22 inside the bracket portion 2, the spacer portion 3 is fixed in close contact with the bracket portions 2 at both ends.

[0035] Furthermore, the spacer sections 3 connected to both sides of the intermediate bracket section 2 are constructed by bending the expansion plate 32 horizontally from the support plate 31, bending the support plate 33 vertically, bending the expansion plate 37 horizontally from the support plate 33, bending the expansion plate 34 horizontally from the support plate 31 so that it overlaps the expansion plate 37, and inserting the locking piece 34a into the locking hole 37a.

[0036] Then, the expanding plate 38 is bent to close the end faces of these spacer portions 3, the insertion piece 38a is bent inside the spacer portion 3 so as to follow the support plate 31, and the locking piece 33c of the other spacer portion 3 is pushed into the locking hole 33b of one spacer portion 3, thereby connecting these spacer portions 3 to each other and fixing them in close contact with the intermediate bracket portion 2.

[0037] (Assembly into a smaller, expanded form) On the other hand, if a small expansion configuration is adopted that slightly increases the area capable of supporting cargo without using the spacer portion 3, it is not necessary to assemble the spacer portion 3, and the spacer portion 3 is simply cut off from each bracket portion 2 along the cut line 30.

[0038] <Attaching to the pallet> (Major expansion form) To increase the surface area of ​​the cargo transport base consisting of the pallet 40 and the pallet size expansion member E1, which has been assembled into this large expanded form, the expanded top plate 1 is placed on the edge of the cargo loading surface 41 of the pallet 40, as shown in Figure 4.

[0039] Then, the support plates 33 and 35 of the spacer section 3 are aligned along the side corresponding to the edge of the pallet 40, and the locking piece 11 is pushed into the hole 42 in the cargo loading surface 41 of the pallet 40. In this way, the pallet size expansion member E1 is attached and fixed to the pallet 40.

[0040] (Small expansion form) On the other hand, to expand the surface area of ​​the cargo transport base consisting of the pallet 40 and the pallet size expansion member E1 using the pallet size expansion member E1 in a small expansion form, the expansion top plate 1 is placed on the cargo loading surface 41 of the pallet 40, as shown in Figure 5.

[0041] Then, the vertical plate 22 of the bracket portion 2 is aligned with the side corresponding to the edge of the pallet 40, and the locking piece 11 is pushed into the hole 42 in the cargo loading surface 41 of the pallet 40. In this way, the pallet size expansion member E1 is attached and fixed to the pallet 40.

[0042] (Comparison of large and small expansion forms) In the large-expansion configuration shown in Figure 6(6A), spacer portions 3 are interposed between both sides of the pallet 40 and the vertical plates 22 of the pallet size expansion member E1. Compared to the small-expansion configuration shown in Figure 6(6B) where spacer portions 3 are not present, the cargo transport base consisting of the pallet 40 and the pallet size expansion member E1 is extended on both sides of the pallet 40 by the thickness t of the spacer portions 3, thereby increasing the area of ​​the top surface capable of supporting cargo.

[0043] <Effects> The pallet size extension member E1 described above is designed so that the extension top plate 1 covers only the portion of the cargo loading surface 41 of the pallet 40 that faces one end. As a result, it becomes considerably smaller than the cargo loading surface 41 of the pallet 40, making it less bulky during transport and storage, easier to handle, and reducing the material costs required for manufacturing, allowing it to be provided at a low cost.

[0044] Furthermore, because the bracket portion 2 forms a triangular tube, it has a robust structure that can firmly support cargo that protrudes from the cargo loading surface 41 of the pallet 40.

[0045] Furthermore, since a detachable spacer portion 3 is attached to the vertical plate 22 of the bracket portion 2, if the cargo overhang is small, the spacer portion 3 can be cut off, and if the cargo overhang is large, the spacer portion 3 can be inserted between the vertical plate 22 and the side of the pallet 40 without cutting it off, thereby efficiently accommodating cargo of different sizes.

[0046] In this way, one type of pallet size expansion member E1 can be used for transporting cargo of two different sizes, thus reducing the costs associated with transporting and storing the pallet size expansion member E1 itself.

[0047] Furthermore, since the load of cargo that extends beyond the pallet 40 is supported not only by the bracket sections 2 at both ends but also by the bracket section 2 in the middle, it has excellent pressure resistance and can stably support heavy cargo.

[0048] Furthermore, as shown in Figure 2, in the blank punched out from corrugated cardboard, the intermediate bracket portion 2 and the spacer portion 3 connected to these bracket portions 2 are arranged between the bracket portions 2 at both ends, allowing for efficient use of materials and reducing material costs.

[0049] Furthermore, since it can be assembled simply by folding and inserting the blank, and does not require tape or glue, it offers excellent work efficiency, can be manufactured with fewer steps, and reduces equipment costs.

[0050] <Other> In the above embodiment, a pallet size expansion member E1 is provided with bracket portions 2 at both ends and in the middle of the expansion top plate 1 to accommodate heavy and large cargo. However, if the cargo to be transported is small and the pallet 40 used is small, or if the cargo is light, the bracket portion 2 in the middle may be omitted.

[0051] Furthermore, in order to accommodate cargo of different sizes, an example was shown in which a spacer section 3 is connected to the bracket section 2 via a cut line 30. However, if only cargo that protrudes little from the pallet 40 is to be transported, the blank may be manufactured without the spacer section 3 from the start.

[0052] Furthermore, while we have illustrated a usage configuration in which two units are used as a set and each unit is attached to both sides of a resin pallet 40, depending on the size of the cargo, it may also be used by attaching only one unit to one side of the pallet 40.

[0053] In addition, although the explanation assumed that the material sheet is made of corrugated paper, it is also possible to use plastic corrugated cardboard made of polypropylene or the like, which is molded into a hollow structure with numerous ribs, as the material sheet.
