[0002] A pallet box including a pallet and a sleeve attached to the pallet is known. In the pallet box disclosed in Patent Document 1, the sleeve has a plurality of side panels and a hinge connecting adjacent side panels of the plurality of side panels. The sleeve can be attached to the pallet in a ring shape and can be unfolded via the hinge. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-200839 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described conventional technology, the sleeve is large and heavy when deployed, making it difficult to handle when attaching and detaching the sleeve.

[0005] For example, when trying to attach a sleeve around a pallet that has already been loaded with cargo, unless a certain amount of space is secured around the pallet, the deployed sleeve will likely hit the surrounding area and hinder the work. As such, the above-mentioned conventional technology has the problem that it is difficult to efficiently attach and detach sleeves to and from pallets.

[0006] The problem to be solved by the present disclosure is to provide a pallet box that allows the work of attaching and detaching sleeves to and from a pallet to be performed efficiently. [Means for solving the problem]

[0007] A pallet box according to one aspect of the present disclosure includes a pallet and an annular sleeve attached to the pallet. The pallet includes a first deck section, a second deck section positioned vertically apart from the first deck section, multiple corner beams connecting the corners of the first deck section and the second deck section, and an intermediate beam positioned midway between two adjacent corner beams. The sleeve includes multiple side panels and multiple vertical frames connecting the multiple side panels in an annular shape. The multiple side panels include an L-shaped side panel consisting of a long piece and a short piece connected to form an L shape. When the L-shaped side panel is attached to the pallet at a position corresponding to one of the two corner beams, the protruding end of the short piece of the L-shaped side panel is positioned closer to the one corner beam than the center of the intermediate beam of the pallet. [Effects of the Invention]

[0008] The present disclosure provides the advantage that the work of attaching and detaching a sleeve to and from a pallet can be performed efficiently. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] 1. First embodiment The pallet box 9 of the first embodiment will be described below with reference to Figures 1 to 7. Note that the directions such as the up and down directions used in the following description are based on the state in which the pallet box 9 is placed on a horizontal plane as shown in Figure 1 etc.

[0011] (Overall structure) The pallet box 9 of the first embodiment includes a pallet 1 that is rectangular in plan view, and a sleeve 2 that is attached to the pallet 1 so as to form a rectangular ring shape in plan view.

[0012] The sleeve 2 is positioned so as to surround the entire space above the pallet 1 when it is attached to the pallet 1 as shown in FIG. 1 etc. (hereinafter, this state will be referred to as the "attached state").

[0013] The pallet box 9 shown in Figure 1 etc. does not have a lid, and the space surrounded by the sleeve 2 is open upward, but it is also preferable for the pallet box 9 to have a lid. In this case, the cargo on the pallet 1 can be enclosed by the pallet 1, the sleeve 2 attached to the pallet 1, and the lid placed on the sleeve 2.

[0014] (palette) As shown in FIG. 7 and other figures, the pallet 1 has an overall rectangular, flat plate-like outer shape.

[0015] The pallet 1 includes a first deck section 11, a second deck section 12, a plurality of corner beams 14, an intermediate beam 16, and a plurality of fork insertion holes 18. The pallet 1 is integrally molded by, for example, injection molding of synthetic resin.

[0016] The first deck section 11 is a rectangular flat plate-shaped portion that constitutes the upper end of the pallet 1. The upper surface of the first deck section 11 constitutes the upper surface of the pallet 1, which is rectangular in plan view.

[0017] The second deck section 12 is a rectangular flat plate-shaped section that constitutes the lower end of the pallet 1. The second deck section 12 is positioned apart from the first deck section 11 in the vertical direction.

[0018] The multiple corner girders 14 are formed to vertically connect the corners of the first deck section 11 and the second deck section 12. In the pallet box 9 of the first embodiment, the multiple corner girders 14 are two corner girders 14 located at both ends of the pallet 1 in one direction (horizontal direction). The two corner girders 14 are located at a distance from each other in one direction.

[0019] The intermediate girder 16 is formed so as to vertically connect the intermediate portions in one direction of the first deck section 11 and the second deck section 12. In the pallet box 9 of the first embodiment, the intermediate girder 16 is located in the middle of the pallet 1 in one direction.

[0020] The multiple fork insertion holes 18 are formed for inserting the forks of a forklift. The multiple fork insertion holes 18 are located between the first deck section 11 and the second deck section 12, and penetrate the pallet 1 in the horizontal direction.

[0021] The multiple fork insertion holes 18 are two fork insertion holes 18 formed between two corner beams 14 located at both ends of the pallet 1 and an intermediate beam 16 located between the two corner beams 14. The two fork insertion holes 18 are located at a distance from each other in one direction, and the intermediate beam 16 is located between the two fork insertion holes 18.

[0022] (sleeve) 1, 5, etc., the sleeve 2 includes a plurality of side plates 3, a plurality of vertical frames 4, and a plurality of hook-and-loop fasteners 5. The plurality of side plates 3 and the plurality of vertical frames 4 are each molded from synthetic resin.

[0023] The multiple side plates 3 include L-shaped side plates 3A. In the pallet box 9 of the first embodiment, the multiple side plates 3 are four side plates 3, each of which is an L-shaped side plate 3A. The four L-shaped side plates 3A have the same dimensions and shape.

[0024] The L-shaped side panel 3A is composed of a long piece 31 and a short piece 32 that are connected to form an L shape in a plan view. The L-shaped side panel 3A can be formed, for example, by subjecting a hollow synthetic resin flat plate to hot bending or hot scoring. The synthetic resin flat plate used here is, for example, a plate material with a structure in which a honeycomb-shaped core material, consisting of hollow hexagonal columns arranged side by side with no gaps between them, is sandwiched on both sides between a pair of skin materials.

[0025] The intersection of long piece 31 and short piece 32 at a right angle forms the corner of L-shaped side panel 3A. The dimension of long piece 31 extending horizontally from the corner of L-shaped side panel 3A is set to be larger than the dimension of short piece 32 extending horizontally from the corner of L-shaped side panel 3A.

[0026] Two recesses 33 are provided at the lower end of the L-shaped side panel 3A, penetrating inward and outward. The two recesses 33 are provided at the lower end of a long piece 31 of the L-shaped side panel 3A. The two recesses 33 are each cut upward from the lower edge of the long piece 31 and are positioned at a distance from each other in the horizontal direction. The two recesses 33 have the same dimensions and shape. Each recess 33 has a rectangular shape with its short side extending up and down and its long side extending horizontally.

[0027] When installed, the lower end of the L-shaped side plate 3A covers the side of the pallet 1, and the two recesses 33 provided at the lower end of the L-shaped side plate 3A are in one-to-one communication with the two fork insertion holes 18 located inside it.

[0028] The multiple vertical frames 4 connect the multiple side panels 3 to form a ring as a whole. In the pallet box 9 of the first embodiment, the multiple vertical frames 4 are four vertical frames 4, each of which is made of a resin frame with an H-shaped horizontal cross section. The four vertical frames 4 have the same dimensions and shape.

[0029] The vertical frame 4 is preferably made of a metal such as aluminum. The vertical frame 4 is configured to connect two L-shaped side plates 3A adjacent to each other in the circumferential direction of the sleeve 2 via the vertical frame 4. As shown in Fig. 3, the vertical frame 4, which has an H-shaped cross section, has an intermediate wall 43 that extends linearly in the vertical direction, and a first recess 41 and a second recess 42 separated by the intermediate wall 43. The first recess 41 and the second recess 42 are both open in the vertical direction and open to opposite sides in the horizontal direction.

[0030] The two adjacent L-shaped side panels 3A are connected via the vertical frame 4 by inserting the edge of the long piece 31 of one of the L-shaped side panels 3A into the first recess 41 of the vertical frame 4 and inserting the edge of the short piece 32 of the other L-shaped side panel 3A into the second recess 42 of the vertical frame 4.

[0031] A plurality of hook-and-loop fasteners 5 are provided across the vertical frame 4 to detachably connect the two L-shaped side panels 3A (see FIG. 2, etc.). Each hook-and-loop fastener 5 includes a first fabric body 51 fixed to the outer surface of the long piece 31 of one of the two L-shaped side panels 3A, and a second fabric body 52 fixed to the outer surface of the short piece 32 of the other L-shaped side panel 3A. The second fabric body 52 is strip-shaped, and one end thereof is fixed to the short piece 32. The other end of the second fabric body 52 is provided so as to be detachably attached to the first fabric body 51 in a planar manner.

[0032] In the pallet box 9 of the first embodiment, three hook-and-loop fasteners 5 are attached to two adjacent L-shaped side panels 3A across the vertical frame 4. The three hook-and-loop fasteners 5 are positioned parallel to each other and spaced apart vertically.

[0033] (Latching device) The pallet box 9 of the first embodiment further includes a plurality of locking devices 6 attached to the sleeve 2. The plurality of locking devices 6 include two locking devices 6 attached to the lower end of the L-shaped side plate 3A.

[0034] 3, 4, etc., the fastener 6 has a first portion 61 that has a U-shaped horizontal cross section and is inserted into the lower end of the L-shaped side panel 3A, and a second portion 62 that has a rectangular piece shape and extends from the first portion 61. The first portion 61 and the second portion 62 intersect at a right angle so that the entire fastener 6 forms an L shape in a plan view.

[0035] The two locking devices 6 are provided at the lower end of the long piece 31 of the L-shaped side plate 3A. The two locking devices 6 are positioned at a distance from each other in the horizontal direction. The two locking devices 6 are attached to two recesses 33 of the L-shaped side plate 3A, respectively.

[0036] In the attached state, the second portions 62 of the fasteners 6 attached to the recesses 33 of the L-shaped side plate 3A are inserted into the fork insertion holes 18 located inside the recesses 33. The two fasteners 6 are inserted into the two fork insertion holes 18 in a one-to-one correspondence.

[0037] Therefore, when the forks of a forklift are inserted into the two fork insertion holes 18 and the pallet 1 is lifted using these forks, the second parts 62 come into contact with the lower ends 181 of the fork insertion holes 18, making it easier to lift the sleeve 2 together with the pallet 1 (see FIG. 4). In other words, by attaching these locking devices 6 to the sleeve 2, the sleeve 2 is prevented from slipping down when the pallet 1 is lifted.

[0038] (Engagement part) In addition, in the pallet box 9 of the first embodiment, a block-shaped engagement portion 45 is provided on at least a predetermined vertical frame 4A among the multiple vertical frames 4 to prevent the sleeve 2 from slipping down when the pallet 1 is lifted (see Figures 3 and 6).

[0039] The engaging portion 45 is fixed to the lower end of the second recess 42 of a predetermined vertical frame 4A. The engaging portion 45 is, for example, a rectangular parallelepiped member that is long in the vertical direction, but the shape of the engaging portion 45 is not limited to this.

[0040] Of the four L-shaped side plates 3A, the short piece 32 of the L-shaped side plate 3A that is inserted into and connected to the second recess 42 of a predetermined vertical frame 4A has an engagement recess 35 for engaging with the engagement part 45. The engagement recess 35 is cut out upward from the lower edge of the short piece 32 of the L-shaped side plate 3A. The engagement recess 35 is rectangular and opens downward and toward the intermediate wall 43 of the vertical frame 4A.

[0041] In the pallet box 9 of the first embodiment, the engagement portion 45 provided on a specified vertical frame 4A engages in the vertical direction with the engagement recess 35 formed in the short piece 32 of the L-shaped side panel 3A, thereby preventing the L-shaped side panel 3A from slipping down relative to the specified vertical frame 4A, and ultimately preventing the sleeve 2 from slipping down when the pallet 1 is lifted.

[0042] (Relative position of L-shaped side panel and pallet) In the attached state shown in Figures 2, 5, etc., the L-shaped side panel 3A is attached to the pallet 1 so as to cover one corner girders 14A of two adjacent corner girders 14 of the pallet 1. In this attached state, the protruding tip 321 of the short piece 32 of the L-shaped side panel 3A is located closer to one corner girder 14A than the center (chain line L1 in the figure) of the intermediate girder 16 of the pallet 1. In Figure 2, the protruding tip 321 of the short piece 32 of the L-shaped side panel 3A is located within the left-right width W1 of one corner girder 14A.

[0043] Therefore, the pallet box 9 of the first embodiment has the advantage that the L-shaped side panels 3A are easy to handle even in a small space. Specifically, even if a large space is not secured around the pallet 1, for example, the sleeve 2 can be easily configured by attaching four L-shaped side panels 3A to surround the cargo on the pallet 1. In the pallet box 9 of the first embodiment, the work of attaching and detaching the sleeve 2 to and from the pallet 1 can be carried out efficiently.

[0044] Moreover, since all four side plates 3 are configured as L-shaped side plates 3A, the side plates 3 can stand on their own. The side plates 3 being able to stand on their own allow the worker to work efficiently.

[0045] 2. Second embodiment A pallet box 9 according to the second embodiment will be described below with reference to Figures 8 to 10. The basic configuration of the second embodiment is the same as that of the first embodiment, so the following will describe in detail the characteristic configuration that differs from that of the first embodiment.

[0046] In the pallet box 9 of the second embodiment, instead of using a hook-and-loop fastener 5 as in the first embodiment, a magnet 37 that exerts magnetic attraction force is used as a means for detachably connecting two L-shaped side panels 3A across the vertical frame 4.

[0047] One of the two L-shaped side plates 3A connected to each other via the vertical frame 4 is provided with a hole 36 and a magnet 37. The other of the two L-shaped side plates 3A is provided with a magnetic body 38.

[0048] Hereinafter, one of the two L-shaped side panels 3A connected to each other via the vertical frame 4 will be referred to as the first L-shaped side panel 3A1, and the other of the two L-shaped side panels 3A will be referred to as the second L-shaped side panel 3A2.

[0049] The hole 36 is formed in the short piece 32 of the first L-shaped side plate 3A1. The hole 36 is formed to penetrate inward and outward at the edge of the short piece 32 that is inserted into the second recess 42 of the vertical frame 4. The hole 36 is cut out in a rectangular shape from the horizontal edge of the short piece 32.

[0050] The shape of the holes 36 is not limited to this, and the holes 36 may be formed so as not to penetrate inside and outside. For example, the holes 36 may have a non-penetrating shape recessed from the outer surface of the edge of the short piece 32, or may have a non-penetrating shape recessed from the inner surface of the edge of the short piece 32.

[0051] The magnet 37 is a disk-shaped permanent magnet. The magnet 37 is disposed in the hole 36 of the first L-shaped side plate 3A1. The shape of the magnet 37 is not limited to this, and the magnet 37 may have another shape, such as a rectangular plate, as long as it is stably held in the hole 36.

[0052] As shown in Figure 9, when the short piece 32 of the first L-shaped side panel 3A1 is inserted into the second recess 42 of the vertical frame 4, the magnet 37 held in the hole portion 36 is accommodated in the second recess 42 of the vertical frame 4 and is positioned opposite the intermediate wall 43 of the vertical frame 4.

[0053] The magnetic body 38 is a rectangular metal plate made of a highly magnetic material such as iron, and is provided on the long piece 31 of the second L-shaped side plate 3A2. In the pallet box 9 of the second embodiment, the long piece 31 of the second L-shaped side plate 3A2 includes a side plate main body 310 and an end frame 315 attached so as to cover the end edge of the side plate main body 310. In the pallet box 9 of the second embodiment, the end frame 315 forms the end edge of the long piece 31 that is inserted into the first recess 41 of the vertical frame 4. The magnetic body 38 is fixed to the end face of the end frame 315.

[0054] As shown in Figure 9, when the end frame 315 of the long piece 31 of the second L-shaped side panel 3A2 is inserted into the first recess 41 of the vertical frame 4, the magnetic body 38 fixed to the end frame 315 is accommodated in the first recess 41 of the vertical frame 4 and is positioned opposite the intermediate wall 43 of the vertical frame 4.

[0055] The magnet 37 and the magnetic body 38 are positioned on either side of the intermediate wall 43 of the vertical frame 4, and exert a magnetic attraction force on each other. As shown in Fig. 8, the magnet 37 and the magnetic body 38 are preferably positioned at the same height. A gap may be formed between the magnet 37 and the intermediate wall 43 of the vertical frame 4, or the magnet 37 may come into contact with the intermediate wall 43. Similarly, a gap may be formed between the magnetic body 38 and the intermediate wall 43 of the vertical frame 4, or the magnetic body 38 may come into contact with the intermediate wall 43.

[0056] 3. Variations The above-described embodiments are merely one of various embodiments of the present disclosure, and various modifications are possible depending on the design and the like as long as the object of the present disclosure can be achieved.

[0057] Various modified examples are listed below. The modified examples listed below can be applied in appropriate combinations. In the description of the modified examples, the same components as those in the above-described embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

[0058] (First Modification) The basic configuration of the first modified example shown in Figure 11 is the same as that of the first embodiment. In the mounted state of the first modified example, the protruding tip 321 of the short piece 32 of the L-shaped side panel 3A is located within the left-right width W2 of the intermediate girder 16 of the pallet 1. However, the protruding tip 321 of the short piece 32 of the L-shaped side panel 3A is located closer to the corner girder 14A covered by the L-shaped side panel 3A than the center of the intermediate girder 16 (the chain line L1 in the figure).

[0059] The first modified example also has the advantage that the L-shaped side plate 3A is easy to handle and is self-standing, allowing the worker to efficiently attach and detach the sleeve 2.

[0060] (Second Modification) The basic configuration of the second modified example shown in Fig. 12 is similar to that of the first embodiment. Fig. 12 is a vertical cross section taken at the same position as Fig. 6 of the first embodiment.

[0061] In the mounted state of the second modified example, the engagement portion 45 for preventing the sleeve 2 from slipping down is fixed at a position in the second recess 42 of the specified vertical frame 4A, spaced a distance above the lower end.

[0062] The engagement recess 35 with which the engagement portion 45 engages is a rectangular cutout at the lower end of the short piece 32 of the L-shaped side panel 3A. The engagement recess 35 is formed at a position spaced a distance above the lower end of the short piece 32. The engagement recess 35 is open toward the intermediate wall 43 of the vertical frame 4A.

[0063] In the second variant pallet box 9, the engagement portion 45 provided on a specified vertical frame 4A engages in the vertical direction with the engagement recess 35 formed in the short piece 32 of the L-shaped side panel 3A, thereby preventing the L-shaped side panel 3A from slipping down.

[0064] (Third Modification) The basic configuration of the third modified example shown in Figure 13 is the same as that of the first embodiment. In the second modified example, in order to prevent the sleeve 2 from slipping down when the pallet 1 is lifted, an engagement portion 318 is provided on the long piece 31 of the L-shaped side plate 3A connected to the first recess 41 of the vertical frame 4, rather than providing the engagement portion 45 on the vertical frame 4.

[0065] In the third modified example, an engagement recess 328 for engaging with the engagement portion 318 is provided in the short piece 32 of the L-shaped side plate 3A that is connected to the second recess 42 of the vertical frame 4. The engagement recess 328 is cut out upward from the lower edge of the short piece 32 of the L-shaped side plate 3A. The engagement recess 328 is rectangular and opens downward and toward the long piece 31 of the adjacent L-shaped side plate 3A.

[0066] In the pallet box 9 of the third modification, the engagement portion 318 of the L-shaped side panel 3A connected to the first recess 41 of the vertical frame 4 engages in the vertical direction with the engagement recess 328 of another L-shaped side panel 3A connected to the second recess 42. This prevents the adjacent L-shaped side panel 3A from sliding down relative to the L-shaped side panel 3A being lifted, and ultimately prevents the sleeve 2 from sliding down when the pallet 1 is lifted.

[0067] (Other variations) In the first and second embodiments, the pallet 1 is configured so that the forks of a forklift can be inserted into the fork insertion holes 18 from two directions, for example, from the front and rear, but the type of the pallet 1 is not limited to this. For example, the pallet 1 may be configured so that the forks can be inserted from all four directions, for example, from the front, rear, left and right.

[0068] In the first and second embodiments, the L-shaped side panel 3A is formed of a hollow synthetic resin flat plate, but the hollow structure here is not limited to the honeycomb structure. For example, the hollow structure of the synthetic resin flat plate constituting the L-shaped side panel 3A may be a hollow structure in which many flat partition walls are arranged in one direction like a harmonica, a hollow structure in which many hollow truncated cones or cylinders are arranged side by side, or a hollow structure in which many cylinders are arranged side by side, each having a shape in which the upper bases of a pair of hollow truncated cones are butted against each other.

[0069] In the first and second embodiments, the L-shaped side panel 3A is formed by bending a flat synthetic resin plate into an L shape, but it is also possible to form the L-shaped side panel 3A by using, for example, two flat synthetic resin plates and an appropriate frame member provided separately from them, and connecting the two flat synthetic resin plates into an L shape via the frame member.

[0070] In the first and second embodiments, the four side plates 3 are not provided with a door structure, but at least one of the four side plates 3 may be provided with a door structure.

[0071] In the first and second embodiments, the sleeve 2 includes four side plates 3, but the number of side plates 3 is not limited to this and may include two or three side plates 3, or five or more side plates 3. Similarly, the sleeve 2 includes four vertical frames 4, but the number of vertical frames 4 is not limited to this and may include two or three vertical frames 4, or five or more vertical frames 4.

[0072] In the first and second embodiments, each of the multiple side plates 3 is configured as an L-shaped side plate 3A, but this is not limited thereto, and it is sufficient that at least one of the multiple side plates 3 is configured as an L-shaped side plate 3A. Furthermore, in the first and second embodiments, the multiple L-shaped side plates 3A have the same dimensions and shapes, but this is not limited thereto, and all or some of the multiple L-shaped side plates 3A may have different dimensions and shapes.

[0073] In the first and second embodiments, the L-shaped side panel 3A is attached to the pallet 1 so that the lower end of the L-shaped side panel 3A covers the corner beam 14 of the pallet 1, but this is not limiting, and for example, the L-shaped side panel 3A may be attached so that the lower end of the L-shaped side panel 3A is positioned above the corner beam 14. In this case as well, it can be said that the L-shaped side panel 3A is attached to the pallet 1 at a position corresponding to the corner beam 14.

[0074] In the second embodiment, the magnet 37 is provided on the first L-shaped side plate 3A1 and the magnetic body 38 is provided on the second L-shaped side plate 3A2, but this is not limiting, and the magnet 37 may be provided on the second L-shaped side plate 3A2 and the magnetic body 38 may be provided on the first L-shaped side plate 3A1. In the second embodiment, the magnetic body 38 is made of a metal member, but the magnetic body 38 may be made of a magnet.

[0075] In the second embodiment, the magnetic body 38 is provided separately from the end frame 315, but the magnetic body 38 may be formed of a part or the entire end frame 315. For example, if the end frame 315 is formed using a highly magnetic material such as iron, rather than aluminum or stainless steel, it is possible to form the magnetic body 38 in the end frame 315.

[0076] 4. Summary As described above based on the embodiment and various modified examples, the pallet box 9 according to the first aspect of the present disclosure includes a pallet 1 and an annular sleeve 2 attached to the pallet 1. The pallet 1 includes a first deck section 11, a second deck section 12 positioned vertically apart from the first deck section 11, a plurality of corner girders 14 vertically connecting the corners of the first deck section 11 and the second deck section 12, and an intermediate girder 16 positioned midway between two adjacent corner girders 14. The sleeve 2 includes a plurality of side panels 3 and a plurality of vertical frames 4 connecting the side panels 3 in an annular shape. The side panels 3 include an L-shaped side panel 3A consisting of a long piece 31 and a short piece 32 connected together to form an L shape. When the L-shaped side panel 3A is attached to the pallet 1 at a position corresponding to one of the two corner beams 14A, the tip 321 of the short piece 32 of the L-shaped side panel 3A is located closer to the one corner beam 14A than the center of the intermediate beam 16 of the pallet 1.

[0077] According to this embodiment, the sleeve 2 can be divided into multiple side plates 3, thereby making each side plate 3 more compact and lightweight. The L-shaped side plate 3A included in the multiple side plates 3 is easy to handle even in a small space and is self-standing, so that the worker can efficiently attach and detach the sleeve 2 to and from the pallet 1.
