DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A storage device according to an embodiment of the present invention will be described in detail below with reference to the drawings. The storage device according to this embodiment includes a pair of bellows members, a sheet member, and a connecting member. Each of the pair of bellows members has 2N (N is a positive integer of 2 or more) triangular pieces that are in the shape of a right-angled isosceles triangle in plan view and are arranged in a stacked manner in the thickness direction, and a connecting piece that is in the shape of a rectangle in plan view and continues to adjacent sides of the triangular pieces and connects two adjacent triangular pieces in the stacking direction. In each bellows member, the triangular pieces other than the triangular pieces located at both ends in the stacking direction of the triangular pieces are continuous with one triangular piece in the stacking direction at the oblique side and connected to the other triangular piece at the adjacent side via the connecting piece. At least N sheet members are provided, and the pair of bellows members are arranged such that adjacent side portions continuing to the connecting pieces of each of the 2N triangular pieces are located on the opposite sides of the opposing bellows members, and the sheet members are interposed between the two adjacent triangular pieces of each pair of bellows members to form a storage area between the two adjacent triangular pieces. The connecting member connects the two adjacent triangular pieces in the arrangement direction of the pair of bellows members.

[0010] As shown in Fig. 1, a storage tool 1 according to the present embodiment is, for example, a bag, and includes a pair of bellows members 11, an outer shell 12, sheet members 131 and 132, a connecting member 14, a pair of locking fittings 151 and 152, and two handles 16. As shown in Fig. 2(A), each of the pair of bellows members 11 has six triangular pieces 111 that are in the shape of a right-angled isosceles triangle in plan view and are arranged overlapping in the thickness direction, and six connecting pieces 112 that are in the shape of a rectangle in plan view, continue to adjacent sides of the triangular pieces 111, and connect two adjacent triangular pieces 111 in the overlapping direction. The pair of bellows members 11 are made of, for example, natural leather. In each bellows member 11, the triangular pieces 111 other than the triangular pieces 111 located at both ends in the overlapping direction of the triangular pieces 111 are continuous with one triangular piece 111 in the overlapping direction at the oblique side portion and connected to the other triangular piece 111 at the adjacent side portion via a connecting piece 112. A pair of bellows members 11 are arranged such that the adjacent side portions continuous with the connecting pieces 112 of each of the six triangular pieces 111 are located on the opposite side to the opposing bellows member 11 sides. A storage area S1 is formed between the two adjacent triangular pieces in each pair of bellows members 11.

[0011] The outer shell body 12 has a pair of outer shell pieces 121 each having a rectangular plate shape and formed by bending both sides of the central portion in the longitudinal direction in the same direction. The triangular pieces 111 located at both ends of the six triangular pieces 111 of each of the pair of bellows members 11 in the overlapping direction are continuous with one adjacent triangular piece 111 in the overlapping direction at the oblique side and are connected to at least one of the two outer shell pieces 121 at the adjacent side. Here, the triangular pieces 111 located at both ends of each of the pair of bellows members 11 in the overlapping direction are joined to the outer shell pieces 121 at the folded-back portions 121a of the outer shell pieces 121.

[0012] The sheet member 131 is formed, for example, from a woven fabric in a rectangular sheet shape, and there are two of them. The sheet member 131 is interposed between two adjacent triangular pieces 111 of each of the pair of bellows members 11 and is attached to the two adjacent triangular pieces 111, forming a storage area S1 between the two adjacent triangular pieces. As shown in FIG. 2(B), the sheet member 131 has two main pieces 1311 that are rectangular sheets and are arranged overlapping each other in the thickness direction, and a connecting piece 1312 that is a long rectangular sheet and is continuous with the main piece 1311 in the entire longitudinal direction of each of both end edges in the short side direction. Here, the connecting piece 1312 is attached to the triangular pieces 111 of the bellows member 11 together with the two main pieces 1311 in a state where it is folded in two at least at both ends in the longitudinal direction by a virtual straight line VL1 that passes through the center in the short side direction and extends in the longitudinal direction. The sheet member 132 is in the form of a rectangular sheet, and is attached to the triangular pieces 111 and the outer shell piece 121 of the outer shell body 12 in a state where the sheet member 132 is interposed between each of the triangular pieces 111 located at both ends of each of the pair of bellows members 11 in the above-mentioned overlapping direction and the outer shell piece 121 of the outer shell body 12, with the triangular pieces 111 continuing from each of the triangular pieces 111 via the connecting pieces 112. Here, the sheet member 132 is attached to the outer shell piece 121 at the folded-back portion 121a of the outer shell piece 121 together with the triangular pieces 111 located at both ends of each of the pair of bellows members 11 in the above-mentioned overlapping direction.

[0013] The connecting member 14 has a shape obtained by bending, for example, a metal plate into a U-shaped cross section, and connects the apexes of two adjacent triangular pieces 111 in the arrangement direction of the pair of bellows members 11.

[0014] The pair of locking fittings 151, 152 are respectively attached to the pair of outer shell pieces 121 of the outer shell body 12. The pair of locking fittings 151, 152 are engaged with each other when the pair of outer shell pieces 121 are closed. The handles 16 are attached to each of the pair of outer shell pieces 121. The stopper fittings 17 are long and have both ends in the longitudinal direction fixed to the peripheries of the pair of outer shell pieces 121, preventing the opening angle of the pair of outer shell pieces 121 from exceeding a preset angle.

[0015] Next, a manufacturing method of the storage tool 1 according to the present embodiment will be described. First, a base material 911 that is the base of the bellows member 11 as shown in FIG. 3 is prepared. The base material 911 is produced, for example, by cutting out from a sheet of natural leather. The base material 911 has a square shape in a plan view, and has two rectangular pieces 9113 arranged such that one apex P1 of two right-angled apexes surrounds one base point P0, two triangular pieces 9111 that are right-angled triangular shapes in a plan view and arranged such that adjacent pieces are adjacent to one side of the two rectangular pieces 9113, and a connecting piece portion 9112 that is rectangular in a plan view and is continuous with the two adjacent rectangular pieces 9113 or the triangular piece portion 9111 and the rectangular piece portion 9113 on each of the two opposing sides.

[0016] Next, each of the multiple connecting piece portions 9112 is mountain-folded along an imaginary mountain fold line MFL that passes through the center of the connecting piece portion 9112 in the short direction and extends in the longitudinal direction of the connecting piece portion 9112, and valley-folded along an imaginary valley fold line VFL that connects the two apexes of each of the two rectangular piece portions 9113, thereby preparing two of the above-mentioned bellows members 11. Next, the pair of bellows members 11 are each arranged such that adjacent side portions continuing to the connecting piece 112 of each triangular piece 111 are positioned on the opposite side to the opposing bellows member 11 sides, as shown in FIG.

[0017] 4, sheet member 131 is inserted between two adjacent triangular pieces 111 of each of the pair of bellows members 11. Then, with sheet member 131 interposed between two adjacent triangular pieces 111 of each of the pair of bellows members 11, two sheet members 131 are attached to the two adjacent triangular pieces 111. Next, the tops of two adjacent triangular pieces 111 in the arrangement direction of the pair of bellows members 11 are connected to each other by connecting member 14.

[0018] Next, the bellows member 11 and the sheet member 132 are respectively attached to the pair of outer shell pieces 121 of the outer shell body 12, and the locking fittings 151, 152, the handle 16 and the stopper fitting 17 are attached to the pair of outer shell pieces 121, thereby completing the storage tool 1.

[0019] As described above, storage tool 1 according to this embodiment can achieve weight reduction while maintaining a luxurious appearance.

[0020] Incidentally, there is provided a bag with one storage space formed inside, and a pocket for storing small items sewn to the inner wall. However, in the case of such a bag, when the bag is carried around, the contents in the pocket may fly out of the pocket and get mixed up inside the bag, making it difficult to organize the stored items. In addition, in the case of such a bag, the contents of the pocket may be difficult to see, making it difficult to know what is put where. For this reason, it has been necessary to organize the contents of the bag using, for example, a bag-in-bag. In contrast, according to the storage tool 1 of this embodiment, the contents of the contents can be clearly seen at a glance and classified and stored, which has the advantage of improving the convenience of the user.

[0021] Also, as a conventional bellows member, for example, there is a pair of rectangular pieces that are rectangular in plan view and have a slit extending from one edge in the short side direction to the center in the short side direction in the central portion, and the pair of rectangular pieces with the slits fitted together are arranged in a stacked manner, and both ends in the longitudinal direction of each rectangular piece are joined to one end of two adjacent rectangular pieces in the overlapping direction. In contrast, according to the storage tool 1 of this embodiment, the bellows member 11 has a structure in which the triangular pieces 111 other than the triangular pieces 111 located at both ends in the overlapping direction of the triangular pieces 111 are continuous with one triangular piece 111 in the overlapping direction at the oblique side portion and connected to the other triangular piece 111 at the adjacent side portion via the connecting piece 112. This allows the opening portion of the storage area S1 to be opened wider than the conventional bellows member described above, which has the advantage of making it easier to insert and remove coins, cards, etc. stored in the storage area S1.

[0022] Also, suppose that the conventional bellows member described above is produced using, for example, six rectangular pieces 991 that are rectangular in plan view, as shown in FIG. 5. When producing a storage device 1 according to the present embodiment that has approximately the same outer dimensions as a storage device using this conventional bellows member, 12 sets of triangular pieces 111 and connecting pieces 112 are used, as shown in FIG. 5. Then, as shown in FIG. 5, it can be seen that the total area of ​​the base material 911 required to produce the triangular pieces 111 and connecting pieces 112 that constitute the bellows member 11 according to the present embodiment is only about 60% of the total area of ​​the base material required to produce the rectangular pieces 991 that constitute the conventional bellows member. In this way, the storage device 1 according to the present embodiment is lighter than the storage device using the conventional bellows member described above, by reducing the amount of base material 911 required to produce the bellows member 11.

[0023] Although the embodiment of the present invention has been described above, the present invention is not limited to the configuration of the above-mentioned embodiment. For example, the bellows member 11 and the outer shell 12 are not limited to being made of natural leather, and may be made of other materials such as synthetic leather.

[0024] In the storage tool manufacturing method described in the embodiment, an example has been described in which a base material 911 having two rectangular pieces 9113, two triangular pieces 9111, and a connecting piece 9112, as shown in Fig. 6, is used. However, the shape of the base material used is not limited to this. For example, as shown in FIG. 5, the base material 2911 may have nine square pieces 29113 arranged in a diamond shape in a planar view with two opposing vertices forming right angles, one of which is arranged so that the angle between two adjacent sides of the two vertices excluding the two right-angled vertices is smaller than the angle between the other two adjacent sides, surrounding a base point P0; two triangular pieces 29111 each having a right-angled triangular shape in a planar view and arranged so that an adjacent piece portion is adjacent to one side of the square piece 29113 arranged at each of both ends in the arrangement direction of the square piece 29113 among the nine square piece parts 29113; and ten connecting pieces 9112 each having a rectangular shape in a planar view and connected to two adjacent square piece parts 29113 in the arrangement direction of the square piece parts 29113 or to the triangular piece 29111 and the square piece 29113 on each of the two opposing sides.

[0025] Then, by mountain folding each of the ten connecting piece portions 9112 of the base material 2911 at imaginary mountain fold lines MFL that pass through the center of the connecting piece portion 9112 in the short direction and extend in the long direction of the connecting piece portion 9112, and valley folding each of the nine square piece portions 29113 at imaginary valley fold lines VFL that connect two vertices other than the two right-angled vertices, a bellows member can be prepared which has 20 triangular pieces that are right-angled triangular in plan view and arranged stacked in the thickness direction, and connecting pieces that are rectangular in plan view and continue to the adjacent side portions of the triangular pieces and connect two adjacent triangular pieces in the overlapping direction, and in which the triangular pieces other than the triangular pieces located at both ends in the overlapping direction are continuous with one of the triangular pieces in the overlapping direction at their hypotenuse portions and connected to the other triangular piece at their adjacent side portions via the connecting pieces.

[0026] In the embodiment, as shown in Fig. 2(B), an example has been described in which the sheet member 131 has two main pieces 1311 and a connecting piece 1312 continuous with the main pieces 1311. However, this is not limited thereto, and the sheet member 3131 may have a structure in which the ends of the two main pieces 1311 in the same direction in the short side direction are continuous, that is, a structure in which a rectangular sheet in a plan view is mountain-folded along a virtual mountain-fold line along a side, as shown in Fig. 7, for example.

[0027] In the embodiment, an example in which the storage tool 1 is a bag has been described, but the present invention is not limited to this, and the storage tool may be a wallet having a similar structure. That is, the outer shell 12 may not have a handle 16 attached thereto, and may have a compact structure overall. An example of a storage tool according to this modification is a storage tool used as a wallet, as shown in FIG. 8. Alternatively, the storage tool may be a bag, such as a card case, a cosmetic pouch, or a gadget pouch, which is used to store items other than a wallet.

[0028] By the way, many of the conventional small wallets have a storage section that is large enough to fit the stored items. However, since the area of ​​the opening of such wallets is small, when taking out cards stored in the storage section, for example, the cards must be slid out one by one, and the user may find it difficult to smoothly insert and remove the cards. Similarly, since the number of coins that can be inserted and removed at one time is limited, the user may find it very difficult to smoothly insert and remove the coins. In particular, when bills are stored folded in thirds, the bills may be rolled up at the edge, making it difficult to insert and remove them. In contrast, according to the present configuration, all the storage sections are opened three-dimensionally in a single opening action, so that the coins, cards, and bills can be seen at a glance, and the bills can be smoothly inserted and removed while preventing the bills from rolling up.

[0029] As shown in FIG. 8, in the storage device according to this modification, the portion VL4 corresponding to the imaginary valley fold line VFL of the base material of the bellows member 11 and the edge of the connecting piece portion 9112 has a structure that connects two vertices PT and PB at the center in the left-right direction of the opening portion of the storage area S1 and the left and right vertices PR and PL on the bottom side of the storage area S1. This allows the bottom side of the storage area S1 to be expanded into a hexagonal shape with vertices at the boundary portion between the connecting piece 112 and the triangular piece 111 and the boundary portion between the adjacent connecting pieces 111. In addition, when a plate-shaped object such as a card is placed in the storage area S1, the opening portion of the storage area S1 cannot be expanded very much, but when a relatively small object such as a coin is placed in the storage area S1, the depth of the storage area S1 can be made relatively shallow by opening the two vertices PT and PB widely so that they are separated from each other. Therefore, there is an advantage that it is easy to take out coins and the like stored in the storage area S1. In addition, when banknotes or a smartphone are stored, both ends in the width direction of the storage area function as stoppers for the banknotes and smartphone, preventing the banknotes or smartphone from falling out of the storage device. Also, since the opening of the storage area S1 does not open too wide, it acts as a guide when removing the banknotes and smartphone, making it easier to remove the banknotes and smartphone.

[0030] Conventional wallets use shoulder gussets, but when bills are stored in them, the corners of the bills may hit the part that is folded inside the shoulder gusset, causing the bills to bend. In contrast, the storage tool of this variation has a structure without shoulder gussets, but the storage area S1 can be opened wide, making it possible to easily remove bills while preventing the corners of the bills from being bent.

[0031] In the embodiment, the storage tool is described as having the outer shell 12, but it may be, for example, a storage tool that does not have the outer shell 12 and has only the bellows member 11, the connecting member 12, and the sheet member 131, and in which the triangular pieces at both ends in the overlapping direction of the plurality of triangular pieces of the bellows member 11 are sewn to the sheet members 131 that are respectively arranged at both ends in the overlapping direction of the plurality of sheet members 131. This storage tool can be used, for example, as a tool for dividing the inside of an existing bag, wallet, etc.

[0032] Although the embodiments and modifications of the present invention have been described above, the present invention is not limited to these. The present invention includes appropriate combinations of the embodiments and modifications, and appropriate modifications thereto. [Industrial Applicability]
