Embodiments for Carrying Out the Invention

[0009] Hereinafter, a storage tool according to an embodiment of the present invention will be described in detail with reference to the drawings. The storage tool 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, in a plan view, a right-angled isosceles triangle shape and 2N triangular pieces (N is a positive integer of 2 or more) arranged by being stacked in the thickness direction, and a rectangular shape in a plan view and a connecting piece that is continuous with an adjacent side portion of the triangular piece and connects two adjacent triangular pieces in the stacking direction. And, in each bellows member, among the triangular pieces other than the triangular pieces located at both ends in the stacking direction of the triangular pieces, one triangular piece is continuous with one of the triangular pieces in the stacking direction at the hypotenuse portion and is connected to the other triangular piece through the connecting piece at the adjacent side portion. There are at least N sheet members, and in a state where the adjacent side portions where the pair of bellows members are continuous with the connecting pieces of each of the 2N triangular pieces are located on the side opposite to the bellows member side facing each other, the sheet members are adhered to two adjacent triangular pieces in a state of being interposed between two adjacent triangular pieces of each of the pair of bellows members, and a storage area is formed between two adjacent triangular pieces. The connecting member connects two adjacent triangular pieces in the arrangement direction of the pair of bellows members.

[0010] As shown in FIG. 1, the storage device 1 according to the present embodiment is, for example, a bag, and includes a pair of bellows members 11, an outer housing 12, sheet members 131 and 132, a connecting member 14, a pair of locking fittings 151 and 152, and two handles 16. Each of the pair of bellows members 11 is, as shown in FIG. 2(A), in the shape of a right-angled isosceles triangle in plan view and includes six triangular pieces 111 arranged in a stacked manner in the thickness direction, and six connecting pieces 112 that are rectangular in plan view and connect two adjacent triangular pieces 111 that are continuous with the adjacent side portions of the triangular pieces 111 in the stacking direction. The pair of bellows members 11 are formed of, for example, natural leather. And for each bellows member 11, the triangular pieces 111 other than the triangular pieces 111 located at both ends in the stacking direction of the triangular pieces 111 are continuous with one of the triangular pieces 111 in the stacking direction at the hypotenuse portion and are connected to the other triangular piece 111 at the adjacent side portion via the connecting piece 112. The 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 side opposite to the side of the bellows member 11 facing each other. A storage area S1 is formed between two adjacent triangular pieces of each of the pair of bellows members 11.

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

[0012] The sheet member 131 is formed, for example, in a rectangular sheet shape from a woven fabric and there are two of them. The sheet member 131 is adhered to two adjacent triangular pieces 111 while being interposed between two adjacent triangular pieces 111 of each of the pair of bellows members 11, and forms an accommodation region S1 between the two adjacent triangular pieces. As shown in FIG. 2(B), this sheet member 131 has two main pieces 1311 that are in a rectangular sheet shape and are arranged overlappingly in the thickness direction, and connecting pieces 1312 that are in a long rectangular sheet shape and are continuous with the main pieces 1311 over the entire longitudinal direction of each of the both end edges in the short direction. Here, the connecting piece 1312 is folded into two at least at both ends in the longitudinal direction by a virtual straight line VL1 that passes through the central portion in the short direction thereof and extends in the longitudinal direction, and is adhered to the triangular piece 111 of the bellows member 11 together with the two main pieces 1311. The sheet member 132 is in a rectangular sheet shape and is interposed between the triangular piece 111 that is continuous with the triangular piece 111 located at both ends of each of the pair of bellows members 11 in the above-described overlapping direction via the connecting piece 112 and the outer shell piece 121 of the outer shell body 12, and is adhered to the triangular piece 111 and the outer shell piece 121. Here, the sheet member 132 is adhered 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-described overlapping direction.

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

[0014] The pair of locking fittings 151 and 152 are respectively adhered to each of the pair of outer shell pieces 121 of the outer shell body 12. The pair of locking fittings 151 and 152 are in a state of being engaged with each other when the pair of outer shell pieces 121 are closed. The handle 16 is attached to each of the pair of outer shell pieces 121. The stopper fitting 17 is long and both ends in the longitudinal direction are fixed to the peripheral portions of the pair of outer shell pieces 121, and prevent the opening angle of the pair of outer shell pieces 121 from becoming equal to or greater than 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 forms the basis of the bellows member 11 as shown in FIG. 3 is prepared. This base material 911 is produced, for example, by cutting out from a natural leather sheet. The base material 911 is square in plan view, and has two square piece portions 9113 in which one of the two right-angled top portions, a top portion P1, is arranged so as to surround one reference point P0, and two triangular piece portions 9111 that are arranged in a right-angled triangular shape in plan view such that adjacent piece portions are adjacent to one side of the two square piece portions 9113, and connection piece portions 9112 that are rectangular in plan view and are continuous with two adjacent square piece portions 9113 or triangular piece portions 9111 and the square piece portion 9113 on each of the two opposing sides.

[0016] Next, for each of the plurality of connection piece portions 9112, a virtual mountain fold line MFL that passes through the central portion in the short side direction of the connection piece portion 9112 and extends in the long side direction of the connection piece portion 9112 is used for mountain folding, and a virtual valley fold line VFL that connects the two top portions in each of the two square piece portions 9113 is used for valley folding, thereby preparing two of the above-described bellows members 11. Subsequently, a pair of bellows members 11 are arranged such that the adjacent side portions that are continuous with the connection pieces 112 of the triangular pieces 111 are located on the side opposite to the bellows member 11 side where they face each other, as shown in FIG. 4.

[0017] Thereafter, as shown by the broken line arrow in FIG. 4, the sheet member 131 is inserted between two adjacent triangular pieces 111 of each of the pair of bellows members 11. Then, with the sheet member 131 interposed between two adjacent triangular pieces 111 of each of the pair of bellows members 11, the two sheet members 131 are adhered 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 by a connecting member 14.

[0018] Subsequently, the bellows member 11 and the sheet member 132 are adhered to each of the pair of outer shell pieces 121 of the outer shell 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, according to the storage device 1 according to the present embodiment, it is possible to achieve weight reduction while maintaining an elegant appearance.

[0020] By the way, there is provided a bag in which one storage space is formed inside, and a pocket for storing small items is sewn on the inner wall. However, in the case of such a bag, when carrying the bag, if the items stored in the pocket jump out of the pocket and get mixed up inside the bag, it may be difficult to organize the stored items. Also, in the case of such a bag, it is difficult to see what is inside the pocket, and there is a risk that it will be difficult to know what was put where. For this reason, for example, it was necessary to organize the contents of the bag using a bag-in-bag or the like. On the other hand, according to the storage device 1 according to the present embodiment, since the stored items inside can be clearly seen at a glance and classified and stored, there is an advantage that the convenience for the user can be improved.

[0021] Further, as a conventional bellows member, for example, a pair of rectangular pieces that are rectangular pieces in a plan view and have slits formed in the central portion extending from one edge in the short direction to the central portion in the short direction, and a plurality of pairs of these rectangular pieces with their slits fitted together are arranged in layers, and both ends in the longitudinal direction of each rectangular piece are adhered to one end of two adjacent rectangular pieces in the overlapping direction. On the other hand, according to the storage device 1 according to the present 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 hypotenuse portion and are connected to the other triangular piece 111 at the adjacent side portion via the connecting piece 112. Thereby, compared with the above-described conventional bellows member, the opening portion of the storage area S1 can be opened wider, and there is an advantage that it becomes easier to take in and out coins, cards, etc. stored in the storage area S1.

[0022] Also, assume that the aforementioned conventional bellows member is manufactured using, for example, six rectangular pieces 991 having a rectangular shape in plan view as shown in FIG. 5. And when manufacturing the storage device 1 according to the present embodiment having substantially the same outer dimensions as the storage device using this conventional bellows member, as shown in FIG. 5, a set of 12 pairs of triangular pieces 111 and connecting pieces 112 will be used. Then, as shown in FIG. 5, it can be understood that the total area of the base material 911 required for manufacturing the triangular pieces 111 and the connecting pieces 112 constituting the bellows member 11 according to the present embodiment is only about 60% of the total area of the base material required for manufacturing the rectangular pieces 991 constituting the conventional bellows member. Thus, the storage device 1 according to the present embodiment is lightweight compared to the storage device using the aforementioned conventional bellows member by reducing the amount of the base material 911 required for manufacturing the bellows member 11.

[0023] As described above, the embodiments of the present invention have been described, but the present invention is not limited to the configurations of the aforementioned embodiments. For example, the bellows member 11 and the outer housing 12 are not limited to those formed of natural leather, and may be formed of other materials such as synthetic leather.

[0024] Also, in the storage furniture manufacturing method described in the embodiment, an example using a base material 911 having two square piece portions 9113, two triangular piece portions 9111, and a connecting piece portion 9112 as shown in FIG. 6 was described. However, the shape of the base material to be used is not limited to this. For example, as shown in FIG. 5, the base material 2911 has a rhombus shape in plan view with two opposite top portions being right angles, and among the two top portions excluding the two right-angled top portions, the angle formed by two adjacent sides of one of the two top portions is smaller than the angle formed by the other two adjacent sides, and nine square piece portions 29113 are arranged so as to surround the base point P0. Also, two triangular piece portions 29111 having a right triangle shape in plan view are arranged such that adjacent piece portions are adjacent to one side of the square piece portion 29113 arranged at each end in the arrangement direction of these square piece portions 29113 among the nine square piece portions 29113. Further, it may have a rectangular shape in plan view and ten connecting piece portions 9112 that are continuous with two adjacent square piece portions 29113 or triangular piece portions 29111 adjacent in the arrangement direction of the square piece portions 29113 and the square piece portion 29113 on each of the two opposite sides.

[0025] Then, for each of the ten connecting piece portions 9112 of this base material 2911, it is mountain-folded along a virtual mountain fold line MFL that passes through the center portion in the short side direction of the connecting piece portion 9112 and extends in the long side direction of the connecting piece portion 9112, and valley-folded along a virtual valley fold line VFL that connects the two top portions excluding the two right-angled top portions in each of the nine square piece portions 29113. As a result, it has twenty triangular pieces having a right triangle shape in plan view and arranged in a stacked manner in the thickness direction, and a connecting piece having a rectangular shape in plan view and connecting two adjacent triangular pieces that are continuous with the adjacent side portions of the triangular pieces and adjacent in the stacking direction. For the triangular pieces other than the triangular pieces located at both ends in the stacking direction, a bellows member may be prepared that is continuous with one triangular piece in the hypotenuse portion and connected to the other triangular piece through the connecting piece at the adjacent side portion.

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

[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 a wallet having a similar structure may be used. That is, the handle 16 may not be attached to the outer shell 12, and the overall structure may be downsized. Examples of the storage tool according to this modification include a storage tool for wallet use as shown in FIG. 8. Alternatively, it may be a storage tool for other uses such as a card case, a cosmetic pouch, a gadget pouch, etc., which stores storage items other than bags and wallets.

[0028] By the way, many conventional small wallets are provided with a storage portion having a size that can exactly accommodate the storage items. However, since such a wallet has a narrow opening area, for example, when taking out a card stored in the storage portion, it is necessary to slide out the cards one by one, and there is a risk that the user may feel it difficult to smoothly insert and remove the cards. In addition, since the number of coins that can be inserted and removed at one time is limited in the same way, there is also a risk that the user may feel it very difficult to smoothly insert and remove the coins. In particular, when the banknote is folded in three and stored, the banknote may be in a state of being rolled up and it may be difficult to insert and remove it. On the other hand, according to this configuration, all the storage portions are interlocked and opened three-dimensionally by one operation of opening, so that it is possible to see at a glance all of the coins, cards, and banknotes, and to smoothly insert and remove the banknotes and the like while preventing the banknotes from being rolled up.

[0029] As shown in Fig. 8, in the storage device according to this modified example, the virtual valley fold line VFL of the base material of the bellows member 11 and the portion VL4 corresponding to the edge of the connecting piece portion 9112 have a structure that connects the two vertices PT and PB at the central portion in the left - right direction of the opening portion of the storage area S1 and the left - right vertices PR and PL at the bottom side of the storage area S1. Thereby, the bottom side of the storage area S1 can be expanded into a hexagonal shape with the boundary portion between the connecting piece 112 and the triangular piece 111 and the boundary portion of the adjacent connecting pieces 111 as vertices. Also, when storing a plate - shaped object such as a card, the opening portion of the storage area S1 cannot be expanded very much. However, when storing a relatively small object such as a coin, the two vertices PT and PB can be opened wide so as to be separated from each other, and the depth of the storage area S1 can be made relatively shallow. Therefore, there is an advantage that coins and the like stored in the storage area S1 can be easily taken out. Further, when storing banknotes or a smartphone, both end portions in the width direction of the storage area function as stoppers for the banknotes and the smartphone. Thus, the dropping of the banknotes or the smartphone from the storage device is suppressed, and since the opening portion of the storage area S1 does not open too wide, there is also an advantage that a guiding effect is exerted when taking out the banknotes and the smartphone, making it easier to take them out.

[0030] By the way, in a conventional wallet, a so - called shoulder gusset is adopted. However, when storing banknotes, there is a risk that the corner of the banknote hits the portion folded inside the shoulder gusset and the corner of the banknote is folded. On the other hand, in the storage device according to this modification, although it has a structure without a so - called shoulder gusset, the storage area S1 can be opened wide. Therefore, it is possible to realize the ease of taking out the banknotes while suppressing the folding of the corners of the banknotes.

[0031] In the embodiment, the case with the outer shell 12 has been described. However, for example, it may be a storage tool that does not have the outer shell 12 and includes only the bellows member 11, the connecting member 12, and the sheet member 131, and both end triangular pieces of the plurality of triangular pieces of the bellows member 11 in the overlapping direction are sewn to the sheet members 131 arranged at both ends in the overlapping direction of the plurality of sheet members 131. This storage tool can be used, for example, for partitioning the interior of an existing bag, wallet, etc.

[0032] As described above, the embodiments and modification examples of the present invention have been explained, but the present invention is not limited to these. The present invention includes those in which the embodiments and modification examples are appropriately combined, and those in which appropriate changes are made thereto.
