DETAILED DESCRIPTION

(12) Hereinafter, an embodiment of the present disclosure will be described with reference to the accompanying drawings. FIG. 1 is a front sectional view showing a state where a crated object 5 is crated in a crating arrangement 100 according to one embodiment of the present disclosure. FIG. 2 is a side sectional view (sectional view across line A-A in FIG. 1 as seen from the direction indicated by arrows A and A) showing a state where the crated object 5 is crated in the crating arrangement 100 according to this embodiment. FIG. 3 is a plan view showing a first structure example of a pallet 1 constituting the crating arrangement 100 according to this embodiment. FIG. 4 is a plan view of a top board 3 constituting the crating arrangement 100 according to this embodiment, as seen from the reverse side of the top board 3. FIG. 3 shows a state with a support board 17 removed from the pallet 1.

(13) With the crating arrangement 100, the crated object 5, which is a product such as an image forming apparatus having been packed in a cardboard case or the like, is crated so that the crated object 5 can be carried on a forklift, a pallet jack, or the like. The crating arrangement 100 includes the pallet 1, a sleeve 2, the top board 3, first fastening belts 4a and 4b, and second fastening belts 4c and 4d.

(14) The pallet 1 is made of wood, and includes three bottom boards 10a to 10c, three leg beams 11a to 11c, three horizontal beams 13a to 13c, a pair of flat boards 15a and 15b, and the support board 17. The bottom boards 10a to 10c make contact with the placement surface. The leg beams 11a to 11c are fixed perpendicularly to the top surfaces of the three bottom boards 10a to 10c. The horizontal beams 13a to 13c are fixed perpendicularly to the leg beams 11a to 11c. The flat boards 15a and 15b are fixed to opposite end parts of the leg beams 11a to 11c so as to bridge them, and underlap the horizontal beams 13a and 13c. The support board 17 is fixed to the top surfaces of the horizontal beams 13a to 13c. The support board 17 has the same rectangular shape as that formed by connecting the outer circumferential edges of the horizontal beams 13a to 13c. In a side surface of the pallet 1, there are formed arm insertion holes 19 surrounded by the bottom boards 10a to 10c, the leg beams 11a to 11c, and the horizontal beams 13a to 13c.

(15) The sleeve 2 is formed of a cardboard sheet in the shape of a cornered column, and is placed over the pallet 1 to wrap the side surface of the crated object 5. The length of the inner circumference of the sleeve 2 (indicated by the dotted line L in FIG. 4) is slightly larger than the length of the outer circumference of the rectangular shape formed by connecting the outer circumferential edges of the horizontal beams 13a to 13c. The cardboard sheet forming the sleeve 2 has its grain direction (the longitudinal direction of the thin tubes formed by flat sheet and corrugated sheets) aligned with the up-down direction of the sleeve 2.

(16) The top board 3 is made of wood, and is placed on a top end part 2b (see FIG. 6) of the sleeve 2. As shown in FIG. 4, to the reverse side of the top board 3, engagement pieces 3a are fixed. The engagement pieces 3a are fixed to the rectangular top board 3, slightly inward of the edges at its four corners, and engage with the inner circumferential edge of the sleeve 2 when the top board 3 is placed on the top end part 2b of the sleeve 2. With the first fastening belts 4a and 4b, the pallet 1 and the crated object 5 are fastened together. With the second fastening belts 4c and 4d, the pallet 1, the sleeve 2, and the top board 3 are fastened together. As the first fastening belts 4a and 4b and the second fastening belts 4c and 4d, for example, crating belts with a thickness of one millimeter made of polyethylene terephthalate are used.

(17) Now, a description will be given of a crating method using the crating arrangement 100. First, as shown in FIG. 5, the crated object 5 is placed on the support board 17 of the pallet 1. Then, the first fastening belts 4a and 4b are inserted into clearances d between the leg beams 11a to 11c and the support board 17 of the pallet 1, are wound around over the crated object 5, and are then each fastened annularly. In this way, the crated object 5 is fixed to the pallet 1. The first fastening belts 4a and 4b are fastened, for example, as follows. Using a commercially available belt fastening machine, with a predetermined tension applied to a belt, with a metal fasting member, opposite end parts of the belt are placed over each other and are fastened to be fixed together; then the surplus parts of the belt at its ends are cut off.

(18) Next, as shown in FIG. 6, the crated object 5 is covered with the sleeve 2 from above. FIG. 7 is an enlarged view of a place (inside the circle in FIG. 6) where the pallet 1 and the sleeve 2 are in contact with each other with the sleeve 2 placed over the pallet 1. Although FIG. 7 illustrates only the right-side (the flat board 15a-side) structure in FIG. 6, the left-side (the flat board 15b-side) structure is quite the same. As shown in FIG. 7, the flat boards 15a and 15b of the pallet 1 each have a side edge in its longitudinal direction (an edge extending in the up-down direction in FIG. 3) protruding from an edge of the support board 17 to a position underlapping a bottom end part 2a of the sleeve 2. The bottom end part 2a of the sleeve 2 is supported on the flat boards 15a and 15b of the pallet 1. The inner circumferential edge of the sleeve 2 engages with a stepped portion 20 formed by the horizontal beams 13a and 13c and the support board 17. This makes it easy to position the sleeve 2 with respect to the pallet 1.

(19) Next, as shown in FIG. 8, the top board 3 is placed on the top end part 2b (see FIG. 6) of the sleeve 2. Engaging the engagement pieces 3a fixed to the reverse side of the top board 3 with the inner circumferential edge of the sleeve 2 makes it easy to position the top board 3 with respect to the sleeve 2. Finally, the second fastening belts 4c and 4d are inserted into the arm insertion holes 19 in the pallet 1, are wound around over the top board 3, and are then each fastened annularly. In this way, the sleeve 2 and the top board 3 are fixed to the pallet 1. The second fastening belts 4c and 4d are fastened in a similar manner as the first fastening belts 4a and 4b.

(20) Here, as shown in FIG. 7, the bottom end parts 2a of the sleeve 2 facing away from each other are supported on the flat boards 15a and 15b. Thus, there is no danger of the bottom end parts 2a of the sleeve 2 biting into the leg beams 11a to 11c and the horizontal beams 13a to 13c when the sleeve 2 and the top board 3 are fastened to the pallet 1 with the second fastening belts 4c and 4d. Thus, it is possible to prevent deformation of the sleeve 2 and loosening of the second fastening belts 4c and 4d resulting from the biting of the bottom end parts 2a.

(21) When the crating arrangement 100 in which the crated object 5 has been crated is carried, the arms of a forklift or a pallet jack are inserted into the arm insertion holes 19 formed in the pallet 1 to lift up and carry the crating arrangement 100. With such a crating arrangement 100, it is unnecessary to pack a product, as the crated object 5, in a cardboard case or the like and then place it on the pallet 1; this makes it easy to crate and carry products and the like, particularly large ones.

(22) With the bottom end part 2a of the sleeve 2 supported on the pallet 1 and with the top board 3 arranged on the top end part 2b of the sleeve 2, the sleeve 2 is held between the pallet 1 and the top board 3. The sleeve 2 has its cardboard sheet grain direction aligned parallel to its up-down direction, and has a high compressive strength in the up-down direction. Thus, even when another crating arrangement 100 is stacked on top of the top board 3, there is no danger of the sleeve 2 squashing. As the sleeve 2, a cardboard sheet having a higher compressive strength in a multilayer structure may be used. It is also possible to use a plurality of the sleeves 2 overlapping each other in a nested structure to increase the compressive strength.

(23) When the crating arrangement 100 is opened, the second fastening belts 4c and 4d are cut to release the fixing among the pallet 1, the sleeve 2, and the top board 3. Then, the top board 3 and the sleeve 2 are removed, and then the first fastening belts 4a and 4b are cut to release the fixing between the pallet 1 and the crated object 5. Thus, it is possible to open the crating arrangement 100 simply by cutting the fastening belts 4a to 4d with scissors or a knife; this eliminates the need to pull out nails and remove boards as with conventional wooden frame crating, and helps significantly reduce the time required for opening. There is no longer a danger of an operator getting hurt with nails or wood splinters.

(24) The pallet 1, the sleeve 2, and the top board 3 are fixed together only with the fastening belts 4a to 4d without adhesive tape or nails; this makes it easy to separate the pallet 1 and the top board 3. Thus, even after the crating arrangement 100 has been opened once, its appearance does not deteriorate due to creases or brakeage, and thus the crating arrangement 100 can be used repeatedly. It is also easy to separate, for disposal, the pallet 1 and the top board 3, which are made of wood, and the sleeve 2, which is made of paper; this improves recyclability.

(25) FIG. 9 is a plan view showing a second structure example of the pallet 1 constituting the crating arrangement 100 according to this embodiment. Like FIG. 3, FIG. 9 and FIG. 10, of which the latter will be described later, show a state with the support board 17 removed from the pallet 1. In the second structure example shown in FIG. 9, opposite end parts of each of the flat boards 15a and 15b in its longitudinal direction protrude from the edges (edges in the up-down direction in FIG. 9) of the support board 17 facing away from each other to positions underlapping the bottom end part 2a of the sleeve 2.

(26) According to the second structure example, in addition to the bottom end parts 2a at two sides (two sides in the left-right direction in FIG. 9) of the sleeve 2 facing away from each other, bottom end parts 2a at two sides (two sides in the up-down direction in FIG. 9) orthogonal to the above-mentioned two sides are also supported on the flat boards 15a and 15b. Thus, it is possible to prevent deformation of the sleeve 2 and loosening of the second fastening belts 4c and 4d resulting from the biting of the bottom end parts 2a more effectively than with the first structure example. The stepped portions 20 are formed on the pallet 1 at its four edges, and thus the sleeve 2 is positioned with respect to the pallet 1 more easily than with the first structure example.

(27) FIG. 10 is a plan view showing a third structure example of the pallet 1 constituting the crating arrangement 100 according to this embodiment. FIG. 11 is a side view of the third structure example of the pallet 1 as seen from below in FIG. 10. In the third structure example shown in FIGS. 10 and 11, a flat board 15c is fixed to central parts of the leg beams 11a to 11c so as to bridge them. Opposite end parts of the flat board 15c in its longitudinal direction protrude from the edges (edges in the up-down direction in FIG. 10) of the support board 17 facing away from each other to positions underlapping the bottom end parts 2a of the sleeve 2.

(28) According to the third structure example, in addition to the bottom end parts 2a at two sides (two sides in the left-right direction in FIG. 10) of the sleeve 2 facing away from each other, the bottom end parts 2a at two sides (two sides in the up-down direction in FIG. 10) orthogonal to the above-mentioned two sides are also supported each at three places of opposite end parts and a central part, on the flat boards 15a, 15b, and 15c. Thus, it is possible to prevent deformation of the sleeve 2 and loosening of the second fastening belts 4c and 4d resulting from the biting of the bottom end parts 2a more effectively than with the second structure example. As in the second structure example, the stepped portions 20 are formed on the pallet 1 at its four edges, and thus it is easy to position the sleeve 2 with respect to the pallet 1.

(29) The embodiments described above are in no way meant to limit the present disclosure, which thus allows for many modifications and variations within the spirit of the present disclosure. For example, although in the above-described embodiment, a pallet 1 and a top board 3 which are made of wood are used, instead, a pallet 1 and a top board 3 which are made of metal or synthetic resin may be used. When the pallet 1 and the top board 3 are molded from metal or resin, for example, the pallet 1 may be formed integrally with the flat boards 15a to 15c and the stepped portions 20, and the top board 3 may be formed integrally with the engagement pieces 3a.

(30) The present disclosure is applicable to crating arrangements in which a large and heavy product is crated. Based on the present disclosure, it is possible to provide a crating arrangement that can reliably protect a crated object and that achieves easy crating and uncrating with use of a small amount of wood.
