Mode for Carrying Out the Invention

[0018] 〔First Embodiment〕 The storage device 1 of the first embodiment of the present invention will be described with reference to FIGS. 1 to 3. In each figure, the X direction (+X direction, -X direction) is the horizontal direction. Also, the Y direction (+Y direction, -Y direction) is a direction that intersects (specifically, is orthogonal to) the X direction and is the horizontal direction. Further, the Z direction (+Z direction, -Z direction) is a direction that intersects (specifically, is orthogonal to) the X direction and the Y direction and is the vertical direction (the perpendicular direction). Also, in the following description, the "X direction" without the +- sign may be used to mean "both the +X direction and the -X direction" or "either one of the +X direction and the -X direction". The "Y direction" without the +- sign may be used to mean "both the +Y direction and the -Y direction" or "either one of the +Y direction and the -Y direction". The "Z direction" without the +- sign may be used to mean "both the +Z direction and the -Z direction" or "either one of the +Z direction and the -Z direction".

[0019] First, the overall structure will be explained, then the structure of each part will be explained, and then its function will be explained.

[0020] (Storage device 1) As shown in Figures 1 and 2, the storage device 1 has a U-shaped cross-section, consisting of a rectangular base 5 and a pair of rectangular wall sections 7 connected by a pair of corners 9; a plurality of cylinders 11 arranged in a row inside the cylinder 3, with one side fixed to one side of the inside surface of the cylinder 3; and a limiting section 19 that limits the opening angle of the pair of wall sections 7. The storage device 1 has the function of storing articles in the plurality of cylinders 11 and making it easy to take out the articles stored in the cylinders 11.

[0021] (Plate material 3) The plate 3 has a bottom surface 5 that extends in the Y direction, and a pair of wall surfaces 7 extending in the Y direction are connected to both sides in the X direction by a pair of corners 9. Specifically, one side of the bottom surface 5 on the -X direction side and one side of the wall surface 7 on the -Z direction side (on the -X direction side) are in contact and connected at one corner 9. Also, one side of the bottom surface 5 on the +X direction side and one side of the wall surface 7 on the -Z direction side (on the other +X direction side) are in contact and connected at the other corner 9. Each of the pair of corners 9 extends in the Y direction and is the part where the wall surface 7 and the bottom surface 15 are bent at approximately a right angle. Note that the Y direction is just one example of a direction.

[0022] In other words, the plate material 3 is a plate-shaped member that opens upward (+Z direction) by a bottom surface portion 5 extending in the Y direction and a pair of wall surfaces 7 extending in the Y direction, and has a U-shaped cross-section that intersects with the Y direction, and is a plate-shaped member in which the corners where the bottom surface portion 5 and the wall surfaces 7 come into contact are bent.

[0023] In this first embodiment, a 1mm thick cardboard with a U-shaped cross-section is used as an example of the plate material 3. Specifically, a rectangular piece of cardboard is prepared in plan view (viewed from above in the Z direction) extending in the Y direction, and two parallel folds (a pair of corners 9) extending in the Y direction are made approximately in the center of the cardboard in the X direction, and the outside of each fold is bent at approximately a right angle in the same direction (+Z direction). In this cardboard, the part located between the two parallel folds is the bottom surface 5, and the parts outside the two parallel folds are a pair of wall surfaces 7.

[0024] (tube 11) The cylinder 11 is a box-shaped body with a rectangular cross-section intersecting the Z-direction, an opening 13 formed at one upper end, and a bottom 15 formed at the other lower end opposite the opening 13.

[0025] The storage container 1 has an opening 13 facing upwards and a bottom 15 facing the bottom surface 5, and is equipped with multiple cylinders 11 that are aligned in a single line in the Y direction inside the U-shaped plate material 3.

[0026] In Figure 1, the multiple cylinders 11 form a set 22 of three cylinders 11. Specifically, as shown in Figure 1, the multiple cylinders 11 are arranged in the following order from the back to the front in the Y direction: first set 22A (arranged in the order of first cylinder 23, second cylinder 24, and third cylinder 25), second set 22B (arranged in the order of first cylinder 23, second cylinder 24, and third cylinder 25), and third set 22C (arranged in the order of first cylinder 23, second cylinder 24, and third cylinder 25). In addition, the first cylinder 23, which does not belong to any set, is located on the front side in the Y direction of the third cylinder 25 of the third set 22C.

[0027] Note that the first cylinder 23, the second cylinder 24, and the third cylinder 25 are all cylinders 11, differing only in one side to which they are fixed to the plate material 3. The first cylinder 23 is a cylinder 11 with its bottom 15 fixed to the bottom surface 5 with an adhesive or other bonding agent. The second cylinder 24 is a cylinder 11 with one side portion 17 (-X direction side) fixed to one wall portion 7 (-X direction side). The third cylinder 25 is a cylinder 11 with the other side portion 17 (+X direction side) fixed to the other wall portion 7 (+X direction side).

[0028] (Restriction section 19) The pair of corners 9 of the plate material 3 are configured to bend. Therefore, when viewed from the Y direction, the angle between the bottom surface 5 and one wall surface 7, and the angle between the bottom surface 5 and the other wall surface 7 can be changed.

[0029] The limiting section 19 limits the opening angle of the pair of wall sections 7. Here, the opening angle of the pair of wall sections 7 refers to the angle formed when the pair of wall sections 7 are opened in a direction that separates them from each other.

[0030] Specifically, as shown in Figures 1 to 3, the limiting section 19 consists of a plurality of rods 18 with through holes formed at both ends, and a shaft 20 that connects the through holes of adjacent rods 18. The two rods 18 connected by the shaft 20 are configured to rotate relative to each other around the shaft 20.

[0031] As shown in Figure 2, the limiting sections 19 are provided at both ends of the storage unit 1 in the Y direction. The limiting section 19 on the +Y direction side has one end fixed to the end of one wall section 7 (the end in the +Y direction) and the other end fixed to the end of the other wall section 7 (the end in the +Y direction). The shaft 20 located in the center of the limiting section 19 on the +Y direction side is fixed to the surface of the cylinder 23 (cylinder 11) that faces outward in the Y direction (the surface facing the +Y direction) and does not belong to any set.

[0032] Furthermore, the limiting portion 19 on the -Y direction side is fixed at one end to the end of one wall portion 7 (the end in the -Y direction) and at the other end to the end of the other wall portion 7 (the end in the -Y direction). In addition, the shaft 20 located in the center of the limiting portion 19 on the -Y direction side is fixed to the surface of the cylinder 23 (cylinder 11) of the first set 22A that faces outward in the Y direction (the surface facing the -Y direction).

[0033] (action) The storage device 1 with the above configuration can store items 2 in each individual cylinder 11 (see Figure 6). As shown in Figure 1, the storage device 1 can be made compact when the pair of wall sections 7 are closed. Therefore, the space occupied when carrying or storing the storage device 1 can be reduced.

[0034] When using the item 2 stored in the cylinder 11, the pair of wall sections 7 can be opened as shown in Figure 2. The opening angle of the pair of wall sections 7 is limited to a predetermined angle by the limiting section 19.

[0035] In each set 22A, 22B, and 22C, the bottom portion 15 of the first cylinder 23 is fixed to the bottom surface portion 5 with adhesive, one side portion 17 (-X direction side) of the second cylinder 24 is fixed to one wall portion 7 (-X direction side) with adhesive, and the other side portion 17 (+X direction side) of the third cylinder 25 is fixed to the other wall portion 7 (+X direction side) with adhesive.

[0036] Therefore, when the pair of wall sections 7 are opened, in each set, the first cylinder 23 separates from the adjacent second cylinder 24, and the second cylinder 24 separates from the adjacent third cylinder 25. Also, the third cylinder 25 of the first set separates from the adjacent first cylinder 23 of the second set, and the third cylinder 25 of the second set separates from the adjacent first cylinder 23. As a result, the items 2 stored in the cylinders 11 and adjacent to each other are separated, making them easier to remove (see Figure 7).

[0037] [Second Embodiment] The storage device 21 of the second embodiment of the present invention will be described using Figures 4 to 7. Hereinafter, the storage device 21 will be described mainly in terms of the limiting portion 27, which is a difference from the storage device 1 of the first embodiment, and components identical to those of the storage device 1 will be denoted by the same reference numerals and their descriptions will be omitted.

[0038] (Restriction section 27) The restricting portion 27 is formed on each of the pair of wall portions 7. The restricting portion 27 on one side (-X direction) consists of a rectangular first restricting plate 28 connected to the wall portion 7 on the one side (-X direction), a rectangular second restricting plate 29 connected to the first restricting plate 28, and a rectangular third restricting plate 30 connected to the second restricting plate 29.

[0039] Specifically, one of the two Y-direction edges of the first restricting plate 28 is bendably connected to the edge of the wall surface 7 on the +Z direction side that is aligned with the Y direction. The other Y-direction edge of the first restricting plate 28 is bendably connected to one of the two Y-direction edges of the second restricting plate 29. Furthermore, the other Y-direction edge of the second restricting plate 29 is bendably connected to one of the two Y-direction edges of the third restricting plate 30.

[0040] Similarly, the other (+X direction side) limiting section 27 is composed of a rectangular first limiting plate 28 connected to the wall surface 7 on the other (+X direction side), a rectangular second limiting plate 29 connected to the first limiting plate 28, and a rectangular third limiting plate 30 connected to the second limiting plate 29.

[0041] Specifically, one of the two Y-direction edges of the first restricting plate 28 is bendably connected to the edge of the other wall surface 7 on the +Z direction side that is aligned with the Y direction. Furthermore, one of the two Y-direction edges of the second restricting plate 29 is bendably connected to the other Y-direction edge of the first restricting plate 28. In addition, one of the two Y-direction edges of the third restricting plate 30 is bendably connected to the other Y-direction edge of the second restricting plate 29.

[0042] (action) Because the restricting section 27 has the above configuration, when the third restricting plate 30 is folded so that it contacts the second restricting plate 29, then the folded third restricting plate 30 and a part of the second restricting plate 29 are folded so that they contact the first restricting plate 28, and then the second restricting plate 29 is folded so that it contacts the wall section 7, the pair of wall sections 7 can be closed as shown in Figures 4 and 6. In this way, the storage device 1 can be made compact, and the space it occupies when carrying or storing the storage device 1 can be reduced.

[0043] Conversely, by separating the second limiting plate 29 from the wall portion 7, then separating the third limiting plate 30 and a portion of the second limiting plate 29 from the first limiting plate 28, then separating the third limiting plate 30 from the second limiting plate 29, and then bringing the third limiting plate 30 into surface contact with the lower part of the wall portion 7, a triangle can be formed by the first limiting plate 28, the second limiting plate 29, the third limiting plate 30 and the wall portion 7, as shown in Figures 5 and 7. This limits the opening angle of the pair of wall portions 7, and maintains the separated state of each cylinder 11. This makes it easier to remove the articles 2 stored in the cylinders 11.

[0044] [Third Embodiment] The storage device 31 of the third embodiment of the present invention will be described using Figures 8 to 11. Hereinafter, the storage device 31 will be mainly described in terms of the number of rows of cylinders 11, which is a difference from the storage device 1 of the first embodiment, and components identical to those of the storage device 1 will be given the same reference numerals and their description will be omitted.

[0045] As shown in Figures 8 and 9, the storage container 31 is equipped with a plurality of cylinders 11 arranged in two rows along the Y direction on the inside of the plate material 3 (the area formed by the bottom surface 5 and a pair of wall surfaces 7).

[0046] The multiple cylinders 11, arranged in two rows in the Y direction, consist of cylinders 11 in which the side portions 17 are alternately fixed to a pair of wall portions 7, and cylinders 11 in which the bottom portion 15 is fixed to the bottom portion 5 without fixing the side portions 17 to the pair of wall portions 7.

[0047] In other words, the multiple cylinders 11 in the first row (the row on the left side of Figure 8) alternately connect the bottom portion 15 to the bottom surface portion 5 and the side portion 17 to the wall portion 7 from one end (-Y direction) to the other end (+Y direction). Similarly, the multiple cylinders 11 in the second row (the row on the right side of Figure 8) alternately connect the side portion 17 to the wall portion 7 and the bottom portion 15 to the bottom surface portion 5 from one end (-Y direction) to the other end (+Y direction).

[0048] Specifically, in the left-hand column of Figure 8, the cylinder 11 located at the back (-Y side) has its bottom 15 joined to the bottom surface 5, but its side 17 is not joined to the wall surface 7. The second cylinder 11 adjacent to the +Y side has its side 17 joined to the wall surface 7, but its bottom 15 is not joined to the bottom surface 5. The third cylinder 11 adjacent to the +Y side has its bottom 15 joined to the bottom surface 5, but its side 17 is not joined to the wall surface 7. The fourth cylinder 11 adjacent to the +Y side has its side 17 joined to the wall surface 7, but its bottom 15 is not joined to the bottom surface 5.

[0049] Specifically, in the right-hand column of Figure 8, the cylinder 11 located at the back (-Y side) has its side portion 17 joined to the wall portion 7, but its bottom portion 15 is not joined to the bottom portion 5. The second cylinder 11 adjacent to the +Y side has its bottom portion 15 joined to the bottom portion 5, but its side portion 17 is not joined to the wall portion 7. The third cylinder 11 adjacent to the +Y side has its side portion 17 joined to the wall portion 7, but its bottom portion 15 is not joined to the bottom portion 5. The fourth cylinder 11 adjacent to the +Y side has its bottom portion 15 joined to the bottom portion 5, but its side portion 17 is not joined to the wall portion 7.

[0050] As described above, when the pair of wall sections 7 are opened, the cylinder 11, whose side section 17 is joined to the wall section 7, moves (opens) in the X direction together with the wall section 7, as shown in Figures 9 and 11, creating a gap between adjacent cylinders 11. Therefore, as shown in Figure 11, it becomes easier to remove the item 2 stored in the cylinder 11.

[0051] [Fourth Embodiment] The storage device 40 of the fourth embodiment of the present invention will be described using Figures 12 to 14. Hereinafter, the storage device 40 will be mainly described in terms of the formation of chamfered surfaces on some of the cylinders 11, which is a difference from the storage device 31 of the third embodiment, and components identical to those of the storage device 1 will be given the same reference numerals and their descriptions will be omitted. Note that in Figure 12, the limiting portion 19 is omitted from the illustration for clarity of the explanation.

[0052] When the pair of wall sections 7 of the storage unit 31 are opened, the cylinder 11, to which the side sections 17 are joined, moves together with the pair of wall sections 7, as described above. As a result, as shown in Figure 12, a portion of the upper end of the cylinder 11 that moved together with the pair of wall sections 7 protrudes from the upper end surface of the cylinder 11, to which the bottom section 15 is joined to the bottom section 5 of the plate material 3, forming a protrusion 32. Consequently, when removing an item 2 stored in the cylinder 11, to which the bottom section 15 is joined to the bottom section 5 of the plate material 3, there is a possibility that the item 2 or one's hand may collide with the protrusion 32.

[0053] To resolve these inconveniences, the storage device 40 has a chamfered surface 41 formed on the upper end surface of the opening 13 of the cylinder 11, which is fixed alternately to a pair of wall sections 7, and is an inclined surface facing inward (inward of the U-shape) of the plate material 3.

[0054] By forming chamfered surfaces 41 on all cylinders 11 joined to the pair of wall portions 7, when the pair of wall portions 7 are opened from a closed state (see Figure 13) to an open state (see Figure 14), the upper end surface of the cylinder 11 joined to the pair of wall portions 7 is prevented from protruding relative to the upper end surface of the cylinder 11 joined to the bottom portion 5. This prevents the occurrence of the above-mentioned problems.

[0055] [Other embodiments] The embodiments described above are illustrative for illustrative purposes only, and the present invention is not limited thereto. Modifications and additions are possible as long as they do not contradict the technical idea of ​​the present invention as can be understood by those skilled in the art from the claims, detailed description of the invention, and drawings.

[0056] For example, in the first and second embodiments described above, in a configuration in which the cylinders 11 are aligned in a single row in the Y direction, three cylinders 11 constitute one set 22, and within one set 22, the first cylinder 22A, whose bottom portion 15 is joined to the bottom surface portion 5, the second cylinder 22B, whose one side portion 17 is joined to one wall portion 7, and the third cylinder 22C, whose other side portion 17 is joined to the other wall portion 7, are arranged in this order, as exemplified by storage devices 1 and 21. However, the present invention is not limited to this configuration, and the order in which the cylinders are aligned in the Y direction may be other than that described above.

[0057] Specifically, a second cylinder may be located at one end in the -Y direction, a first cylinder may be adjacent to the second cylinder, a third cylinder may be adjacent to the first cylinder, and a first cylinder may be adjacent to the third cylinder.

[0058] Furthermore, the three cylinders 11 that make up one set 22 may consist of only two cylinders. Specifically, the two cylinders that make up one set 22 may consist of only the first cylinder 23 and the second cylinder 24. In this case, the side portions 17 of the multiple cylinders 11 aligned in a single row in the Y direction are alternately joined to one wall portion 7 and the other wall portion 7. In this case, the bottom portion 15 is not joined to the bottom portion 5.

[0059] Furthermore, in the first embodiment, a configuration was illustrated in which the shaft 20 located in the center of the limiting portion 19 is fixed to the cylinders 11 located at both ends in the Y direction. However, the shaft 20 located in the center of the limiting portion 19 may not be fixed to the cylinders 11 and may be in a free state. [Explanation of symbols]
