Description

Technical Field

[0001] The present invention relates to a rucksack that is excellent in visibility and storage of articles housed therein and has improved handleability.

Background Art

[0002] Generally, rucksacks for storing and transporting articles are often vertically long because they are often carried on the back by the user. For this reason, as a rucksack, there is a need for one that is excellent in storage when stacking articles in the vertical direction and has excellent visibility so that articles stored near the bottom wall can be easily discovered at a glance when storing a large number of articles.

[0003] In order to meet the above requirements, in a vertically long rucksack, a partition for partitioning the inside into upper and lower two stages is detachably provided (see, for example, Patent Document 1). According to the backpack (rucksack) disclosed in Patent Document 1, by providing a partition, articles packed in the lower end portion of the rucksack can be easily taken out, and when the partition is removed, large articles can be accommodated.

[0004] Further, in a vertically long rucksack, a lower surface portion provided between a pair of side surface portions and a gusset portion provided between a pair of side surface portions are provided, and an inner fabric material that defines a storage portion is provided inward at a predetermined interval from a gusset portion skin material that constitutes the gusset portion, so that a sub-storage portion is formed, and a sub-opening portion that opens along the height direction of the gusset portion is provided in the gusset portion skin material (see, for example, Patent Document 2). According to the rucksack disclosed in Patent Document 2, it is said that articles can be easily stored or taken out in the sub-storage portion through the sub-opening portion provided along the height direction of the gusset portion.

Summary of the Invention

Problems to be Solved by the Invention

[0006] According to the backpacks described in Patent Documents 1 and 2, as described above, since a member for partitioning the inside of the backpack is provided, articles can be stored separately in a plurality of storage locations.

[0007] However, the partitions and inner lining materials provided in the backpacks described in Patent Documents 1 and 2 are merely members for simply partitioning the internal space, so there is a risk that the stored articles may be in an unstable state inside. In this case, since it becomes difficult to take out the articles, there is a problem of inferior storage performance and handling performance. Furthermore, when the above configuration is adopted, it becomes difficult to ensure the visibility of the stored articles, so there is also a problem of inferior handling performance when taking in and out the articles.

[0008] In recent years, it has become clear that so-called inattentive-dominant characteristics such as attention deficit hyperactivity disorder are observed to a certain extent regardless of whether the person is a child or an adult, and it is widely recognized that these are not at all rare characteristics. When having such characteristics, for example, when the target article is hidden in the shade inside the backpack and cannot be visually recognized, it takes a very long time to find it, or there is a risk that it may be necessary to take out all the articles in the backpack and search for it. From such a viewpoint, it has been urgently required to further improve the visibility and storage performance of articles in the backpack and to improve the handling performance.

[0009] The present invention has been made in view of the above problems, and an object thereof is to provide a backpack that can efficiently and stably store articles, can easily visually recognize the stored articles, is easy to take in and out articles, and is excellent in storage performance, visibility, and handling performance.

Means for Solving the Problem

[0010] To solve the above problems, the inventors of the present invention have conducted intensive studies. As a result, first, by partitioning the article storage space of the backpack into a bottom wall side and a top wall side and providing a partition storage member in the form of a bag that opens upward, it has been found that articles can be stored efficiently and stably in a plurality of storage locations, and excellent visibility can be ensured. At the same time, it has been found that by installing the partition storage member so as to limit the opening degree between one storage body and the other storage body within a predetermined range, it is possible to suppress the backpack from becoming unstable in posture or the articles from popping out when taking in and out the articles, and the handleability is further improved. And when the article storage part is opened by separating one storage body from the other storage body, the bag-shaped partition storage member can be three-dimensionally deployed, and when one storage body and the other storage body are combined and closed, the bag-shaped partition storage member can be folded and accommodated in the article storage space, and it has been found that even better handleability can be obtained, and the present invention has been completed.

[0011] That is, the present invention is a rucksack having an article storage portion with an interior serving as an article storage space and including a backrest surface facing the user's back during use, and a shoulder belt attached so as to extend outward from the backrest surface of the article storage portion. The article storage portion includes one storage body including one opening provided on the side opposite to the backrest surface, and another storage body provided with another opening corresponding to the one opening of the one storage body. The article storage space is secured as a space covered by the one storage body and the other storage body when the one opening and the other opening are combined with each other. The one storage body has a back wall with an outer surface serving as the backrest surface, and a pair of side walls, a bottom wall, and a top wall arranged so as to surround the back wall and extending from the periphery of the back wall toward the one opening. The other storage body has a front wall arranged so as to face the back wall when combined with the one storage body, and a pair of side walls, a bottom wall, and a top wall arranged so as to surround the front wall and extending from the periphery of the front wall toward the other opening. The one storage body and the other storage body are openable in a butterfly shape with a support piece provided to connect one of the pair of side walls provided in each of them as a fulcrum. The space between the one opening and the other opening is made openable and closable by a fastener extending from the one side wall of each of the one storage body and the other storage body through the top wall, the other side wall, and the bottom wall in sequence to reach the one side wall. In the article storage space, one or more partition storage members that partition the article storage space into two or more parts on the bottom wall side and the top wall side are installed between the back wall and the front wall so as to limit the opening degree between the one storage body and the other storage body within a predetermined range. The partition storage member is configured in a bag shape opening on the top wall side, and is three-dimensionally deployable with the one side wall side as a fulcrum when the one storage body and the other storage body are separated to open the article storage portion, and is foldable and accommodable in the article storage space when the one storage body and the other storage body are combined and closed. A rucksack is provided, which is characterized by the above features.

[0012] In the backpack of the present invention, in the above configuration, the partition storage member may be adopted to be installed at two positions, namely, near the middle of the bottom wall and the top wall and near the bottom wall in the article storage space.

[0013] In the backpack of the present invention, in the above configuration, among the partition storage members provided in one or more, at least any one of them may adopt a configuration in which the inside is partitioned into two or more.

[0014] In the backpack of the present invention, in the above configuration, among the partition storage members provided in one or more, at least any one of them may adopt a configuration in which one or more small pockets capable of accommodating articles are further provided inside.

[0015] In the backpack of the present invention, in the above configuration, it is more preferable that the small pocket includes a transparent resin sheet or a see-through material through which the inside of the small pocket can be visually recognized from the outside.

[0016] In the backpack of the present invention, in the above configuration, among the partition storage members provided in one or more, at least any one of them may adopt a configuration in which one or more tag pockets made of a transparent resin sheet into which tags can be inserted are provided on at least one of the outer surface side and the inner surface side of the partition storage member.

[0017] Note that the "double-opening" described in this specification refers to a left-and-right double-opening structure in the horizontal width direction, and also refers to an opening and closing structure also called a French door.

Effects of the Invention

[0018] According to the backpack of the present invention, a partition storage member in the shape of an open-top bag is provided, which partitions the article storage space into a bottom wall side and a top wall side, and is installed so as to limit the opening degree between one storage body and the other storage body within a predetermined range. When the article storage part is opened like a double door, the bag-shaped partition storage member can be three-dimensionally deployed, and when the article storage part is closed, the bag-shaped partition storage member is folded and can be stored in the article storage space, adopting such a configuration. As described above, by providing the bag-shaped partition storage member that partitions the article storage space, articles can be efficiently and stably stored in a plurality of storage locations, and excellent visibility can be ensured. Further, by the partition storage member restricting the opening degree between the two storage bodies, it is possible to suppress the backpack from becoming unstable in posture or the articles from popping out when taking in and out the articles, ensuring excellent handleability. Also, when the article storage part is opened like a double door, since the partition storage member can be three-dimensionally deployed, articles can be stored more efficiently and the usability when taking in and out the articles is excellent. On the other hand, when the article storage part is closed, since the partition storage member is folded and can be stored in the article storage space, it is possible to store it compactly and beautifully. Therefore, it is possible to realize a backpack that can efficiently and stably store articles, easily view the stored articles, is easy to take in and out articles, and is excellent in storage performance, visibility, and handleability.

Embodiments for Carrying out the Invention

[0021] Hereinafter, embodiments of a backpack according to the present invention will be given and described in detail with appropriate reference to the drawings. In the following description, for the purpose of making the features of the backpack of the present invention easier to understand, each drawing used may, for convenience, show a characteristic part slightly enlarged, and the dimensional ratios of each component may be different from the actual ones. Also, the materials, dimensions, etc. exemplified in the following description are merely examples, and the present invention is not limited thereto, and it is possible to make appropriate changes and implement it within the scope of not changing the gist thereof.

[0022] <Overall Structure of Backpack> The overall structure of the backpack of this embodiment will be described below. FIG. 1 is a view for explaining the backpack 1 of this embodiment, and is a perspective view showing the state where the article storage part 2 is closed from obliquely above the front wall 40. FIG. 2 is a perspective view showing it from obliquely above the rear wall 30. FIG. 3 is a perspective view showing the state where the article storage part 2 is opened and the bag-shaped partition storage members 7 and 8 are three-dimensionally expanded from obliquely above the other side walls 34 and 44. FIG. 4 is a perspective view showing it from obliquely above the top walls 31 and 41. FIG. 5 is a schematic view showing the state where the article storage part 2 is opened and the bag-shaped partition storage members 7 and 8 are three-dimensionally expanded from the other side wall sides 34 and 44. FIG. 6 is a schematic view showing the state where the article storage part 2 is closed from the other side walls 34 and 44 side. FIG. 7 is an end view taken along line A-A shown in FIG. 5, and FIG. 8 is an end view taken along line B-B shown in FIG. 5. Also, FIG. 9 is an end view taken along line C-C shown in FIG. 6, and FIG. 10 is an end view taken along line D-D shown in FIG. 6. In the following description, "upward" means the direction represented by the symbol "U" shown in FIGS. 1 to 3 and FIGS. 5 and 6, and "downward" means the direction represented by the symbol "D" shown in the same figures. That is, the above symbols "U" and "D" mean upward or downward in the posture where the user carries it using the shoulder belt 9.

[0023] As shown in FIG. 1 (also refer to FIGS. 2 to 6 as appropriate), the backpack 1 of this embodiment has an internal article storage space 2A, and includes an article storage portion 2 including a backrest surface 3a facing the user's back during use, and a shoulder belt 9 attached so as to extend outward from the backrest surface 3a of the article storage portion 2, and is generally configured.

[0024] The backpack 1 of this embodiment can carry articles (not shown) stored in the article storage space 2A of the article storage portion 2 when the user carries it on the back by the shoulder belt 9. In addition, in the illustrated backpack 1, a handgrip 35 that allows the user to hold and lift the backpack 1 by hand is attached to the top wall 31 of one storage body 3.

[0025] The article storage portion 2 is composed of one storage body 3 including one opening 3A provided on the side opposite to the backrest surface 3a, and the other storage body 4 provided with the other opening 4A so as to correspond to the one opening 3A of the one storage body 3. Thus, its outer shell is configured. The article storage portion 2 secures a hollow article storage space 2A covered by the one storage body 3 and the other storage body 4 when the one opening 3A and the other opening 4A are combined with each other.

[0026] One storage body 3 has a back wall 30 with the outer surface side being the backrest surface 3a, and a pair of side walls 33, 34, a bottom wall 32, and a top wall 31 that are arranged so as to surround the back wall 30 and extend from the peripheral edge 30a of the back wall 30 toward the one opening 3A.

[0027] The other storage body 4 has a front wall 40 arranged to face the back wall 30 when combined with the one storage body 3, and a pair of side walls 43, 44, a bottom wall 42, and a top wall 41 that are arranged so as to surround the front wall 40 and extend from the peripheral edge 40a of the front wall 40 toward the other opening 4A.

[0028] Also, in the illustrated example, the extending lengths of the bottom wall 32, the top wall 31, and the pair of side walls 33, 34 from the back wall 30 in one storage body 3 are configured to be larger than the extending lengths of the bottom wall 42, the top wall 41, and the pair of side walls 43, 44 from the front wall 40 in the other storage body 4. Thereby, although the dimensions in the thickness direction of the backpack 1 are different between one storage body 3 and the other storage body 4, generally, considering the opening and closing operation, the posture during the operation of taking in and out articles, the handling property, the storage property, etc., the storage body on the back wall side is configured to have a thicker dimension.

[0029] As shown in FIGS. 3 to 5, one storage body 3 and the other storage body 4 are configured to be openable in a double - leaf manner with a support piece 5 (see FIG. 1) provided to connect one side wall 33, 43 of each of the pair of side walls 33, 34 provided in each of them as a fulcrum. At the same time, between one opening 3A and the other opening 4A of one storage body 3 and the other storage body 4, it is made openable and closable by a fastener 6. More specifically, the fastener 6 extends continuously from one side wall 33, 43 of one storage body 3 and the other storage body 4, via the top walls 31, 41, the other side walls 34, 44, and the bottom walls 32, 42 in sequence, and reaches one side wall 33, 43. And one storage body 3 and the other storage body 4 are made openable and closable with the position of the end of the support piece 5 where the fastener 6 is not provided on the side of one side wall 33, 43 as a fulcrum.

[0030] The entire inner wall surfaces of one storage body 3 and the other storage body 4 that constitute the article storage portion 2 are covered with, for example, a fabric that has been subjected to water - repellent processing (or waterproof processing) in a form that does not prevent one storage body 3 and the other storage body 4 from being openable and closable.

[0031] In the article storage space 2A secured inside the article storage section 2, one or more partition storage members are installed to partition the article storage space 2A into two or more sections on the bottom wall 32, 42 side and the top wall 31, 41 side. In the example shown in FIGS. 3 to 5, etc., the upper partition storage member 7 is arranged at a position near the middle in the longitudinal direction of the article storage space 2A (refer to the vertical direction of the arrows U and D in FIG. 3 or FIG. 5), and the lower partition storage member 8 is arranged near the bottom walls 32, 42. Thus, the partition storage members are installed at two locations in total. As a result, the article storage space 2A is substantially partitioned into two spaces (two rooms) in general by the upper partition storage member 7.

[0032] In addition, the upper partition storage member 7 and the lower partition storage member 8 provided in the backpack 1 of the present embodiment are installed so as to limit the opening degree between one storage body 3 and the other storage body 4 within a predetermined range between the back wall 30 and the front wall 40 by optimally setting the size of the bottom cloth 71 or the bottom cloth 81.

[0033] As shown in FIGS. 3 to 5, the backpack 1 of the present embodiment is configured such that the upper partition storage member 7 and the lower partition storage member 8 are formed in a bag shape that opens to the top wall 31, 41 side, and when the article storage section 2 is opened by separating one storage body 3 and the other storage body 4, it is configured to be three-dimensionally deployable with one side wall 33, 43 side as a fulcrum. At the same time, the upper partition storage member 7 and the lower partition storage member 8 are configured to be foldable and accommodable in the article storage space 2A when one storage body 3 and the other storage body 4 are combined and closed.

[0034] The material of one storage body 3 and the other storage body 4 is not particularly limited, and a sheet material made of a flexible material such as a resin material generally used as the main body material of the backpack can be adopted without any limitation. Examples of such a flexible resin material include sheet materials made of polyethylene, polyethylene terephthalate, polypropylene, etc.

[0035] The upper compartment storage member 7 has a front cloth 72, a rear cloth 73, and a pair of side cloths 74a and 74b provided so as to rise from the periphery of the bottom cloth 71 described above, and is configured in a substantially bag shape with an opening at the top.

[0036] The bottom cloth 71 is stretched between the rear wall 30 and the front wall 40, functions as the bottom plate in the bag-shaped upper compartment storage member 7, and is configured to support the illustrated article stored in the upper compartment storage member 7 from below. Similar to the bottom cloth 71, the front cloth 72 is stretched between the rear wall 30 and the front wall 40 and is disposed on the side of the other side walls 34 and 44 in the article storage space 2A. Also, the rear cloth 73 is stretched between the rear wall 30 and the front wall 40 and is disposed on the side of one of the side walls 33 and 43 in the article storage space 2A.

[0037] The pair of side cloths 74a and 74b are provided so as to connect between the front cloth 72 and the rear cloth 73. One side cloth 74a is disposed on the front wall 40 side, and the other side cloth 74b is disposed on the rear wall 30 side. Also, in the examples shown in FIGS. 3 and 4, one side cloth 74a is attached to the front wall 40 so as to form two small pockets 74A and 74A in the gap with the front wall 40, and the other side cloth 74b is attached to the rear wall 30 so as to form one small pocket 74B in the gap with the rear wall 30.

[0038] As shown in the end view of FIG. 7, when the upper compartment storage member 7 opens the article storage section 2 by separating one storage body 3 and the other storage body 4, the upper compartment storage member 7 is three-dimensionally deployed with one of the side walls 33 and 43 as a fulcrum. By setting the upper compartment storage member 7 in the deployed state, it becomes possible to store articles in the bag-shaped upper compartment storage member 7.

[0039] On the one hand, as shown in the end view of FIG. 9, when the article storage section 2 is closed by combining one storage body 3 and the other storage body 4, the upper compartment storage member 7 is folded around the position of a partition plate 75, the details of which will be described later, so as to be compressed and stored within the article accommodation space 2A. Further, the upper compartment storage member 7 is flexibly bent according to the articles stored therein, so as to be compactly stored within the article accommodation space 2A.

[0040] In addition, in FIGS. 7 and 9, for the sake of illustration, the reference numerals of one side wall 33, 43 and the support piece 5 are shown so as to generally indicate the same location.

[0041] The lower compartment storage member 8 has a front cloth 82 and a rear cloth 83 provided so as to rise from the periphery of the bottom cloth 81 described above, and is configured in a generally bag shape with an opening at the top. Similar to the upper compartment storage member 7, the bottom cloth 81 is stretched between the rear wall 30 and the front wall 40, so as to function as the bottom plate of the bag-shaped lower compartment storage member 8, and is configured to support articles (not shown) stored in the lower compartment storage member 8 from below. Similar to the bottom cloth 81, the front cloth 82 is stretched between the rear wall 30 and the front wall 40, and is disposed on the side of the other side walls 34, 44 in the article accommodation space 2A. Further, the rear cloth 83 is also stretched between the rear wall 30 and the front wall 40, and is disposed on the side of one side walls 33, 43 in the article accommodation space 2A. Note that the lower compartment storage member 8 is different from the upper compartment storage member 7 in that it does not have side cloths, and is configured such that the articles stored therein can be prevented from falling, etc. by the rear wall 30 and the front wall 40.

[0042] As shown in the end view of FIG. 8, when the article storage section 2 is opened by separating one storage body 3 and the other storage body 4, similar to the upper compartment storage member 7, the lower compartment storage member 8 is three-dimensionally deployed with one side walls 33, 43 as the fulcrum. By setting the lower compartment storage member 8 in the deployed state, it becomes possible to store articles in the bag-shaped lower compartment storage member 8.

[0043] On the other hand, as shown in the end view of FIG. 10, when the article storage section 2 is closed by combining one storage body 3 and the other storage body 4, the lower compartment storage member 8 is folded about the position of the fold margin 8a so as to be compressed and stored within the article storage space 2A. Also, like the upper compartment storage member 7, the lower compartment storage member 8 can be flexibly bent according to the articles stored therein, and thus can be compactly stored within the article storage space 2A.

[0044] The materials of the upper compartment storage member 7 and the lower compartment storage member 8 are not particularly limited, and similar to one storage body 3 and the other storage body 4, for example, a flexible sheet material made of polyethylene, polyethylene terephthalate, polypropylene, etc. can be adopted without any limitation.

[0045] The support pieces 5 are provided so as to straddle the respective one side walls 33, 34 of one storage body 3 and the other storage body 4 so as to connect one storage body 3 and the other storage body 4. The support pieces 5 serve as a fulcrum between one storage body 3 and the other storage body 4 when performing the opening and closing operation of the article storage section 2. The material of the support pieces 5 is not particularly limited, and for example, similar to one storage body 3 and the other storage body 4, a sheet-like material made of a resin material having flexibility can be adopted without any limitation.

[0046] As described above, the fastener 6 connects one storage body 3 and the other storage body 4 so as to be openable and closable between one opening 3A and the other opening 4A. The fastener 6 seals by sequentially engaging an element 61 composed of a pair of engaging teeth extending to one opening 3A and the other opening 4A by a sliding operation of a slider 62. In the illustrated example, two sliders 62 are attached to the element 61, and the respective sliders 62, 62 are configured to be slidable along the extending direction of the element 61.

[0047] On the other hand, when the sliders 62, 62 are slid in the direction opposite to the closing of the fastener 6, the element 61 composed of a pair of engaging teeth is disengaged from the engaged state, so that the one opening 3A and the other opening 4A can be separated. Thereby, the one storage body 3 and the other storage body 4 can be opened like a double door.

[0048] The fastener 6 is not particularly limited, and can be appropriately selected according to the specifications of the backpack 1, etc., regardless of whether it is made of metal or resin.

[0049] As described above, the shoulder belt 9 is attached to the backrest surface 3a on the outer surface side of the back wall 30 and is configured so that the user can carry the backpack 1 on the back. The shoulder belt 9 is also not particularly limited, and for example, a structure that can be adjusted in length so that the user can easily use it, such as one made of various resin materials, can be adopted without any limitation.

[0050] In the present embodiment, as described above, as an example of the partition storage member, two, i.e., the upper partition storage member 7 and the lower partition storage member 8, are provided, and an example in which the space is roughly partitioned into two upper and lower spaces (two rooms) is described, but it is not limited to this. For example, a configuration in which the article storage space is substantially partitioned into three or more rooms by providing three or more partition storage members may be adopted, or a configuration in which only one partition storage member is provided may also be possible.

[0051] Also, in the present embodiment, the interiors of the upper partition storage member 7 and the lower partition storage member 8 may be configured as one storage space, but the interior of any of these may be partitioned into two or more. In the example shown in FIGS. 3 to 5, one partition plate 75 is provided so as to partition the interior of the bag-shaped upper partition storage member 7 into two spaces on the back wall 30 side and the front wall 40 side. On the other hand, in the illustrated example, no partition plate is provided inside the lower partition storage member 8, and the interior of the lower partition storage member 8 is configured as one storage space.

[0052] The material of the partition plate 75 is not particularly limited, and any material having a hardness capable of maintaining the function as a partition plate may be used. For example, plate-shaped resin materials such as polyethylene and polypropylene can be adopted without any limitation. Further, the partition plate 75 can also be configured to be covered with a fabric (or waterproof processed) fabric not shown, for example, with water repellent processing.

[0053] Also, the method of partitioning the inside of the upper compartment storage member 7 and the lower compartment storage member 8 is not limited to the structure using the partition plate 75 described above. For example, in the upper compartment storage member 7 and the lower compartment storage member 8, a structure in which the inside is partitioned by a method such as folding and sewing the bottom cloths 71 and 81 may be adopted.

[0054] Also, in the present embodiment, one or more small pockets capable of accommodating articles may be provided in at least any one of the compartment storage members provided in one or more. In the examples shown in FIGS. 3 to 5, small pockets 76 are provided at four locations, two locations on each of the two sides of the partition plate 75, inside the upper compartment storage member 7. On the other hand, in the illustrated example, since the lower compartment storage member 8 has a shallow bottom, it is configured not to have a small pocket inside.

[0055] According to the backpack 1 of the present embodiment, by adopting the configuration in which the small pockets 76 are provided as described above, for example, it becomes possible to store small articles separately for each of their attributes, so that the storage property and handleability are more excellent.

[0056] From the viewpoint of visibility and handleability of the stored articles, it is more preferable that the small pocket 76 has a configuration including, for example, a transparent resin sheet whose inside is visible from the outside, or a see-through material.

[0057] In FIGS. 3 and 4, small pockets 76 provided on both sides of the partition plate 75 are illustrated and described. However, the small pockets are not limited to such a configuration. For example, a configuration in which the small pocket 76 is provided only on one side of the partition plate 75 may be used. Further, as the small pocket, a configuration that utilizes a space secured as a gap between members, such as the small pocket 74A and the small pocket 74B described above, may be used.

[0058] Also, in the present embodiment, although detailed illustration is omitted, at least one of the partition storage members provided in one or more may be provided with one or more tag pockets made of a transparent resin sheet into which a tag can be inserted on at least one of the outer surface side and the inner surface side of the partition storage member.

[0059] By providing the above-described tag pocket and inserting a tag made of paper or the like on which attribute information of the stored article is described, it is possible to visually recognize at a glance what is stored at that position. As a result, when taking out an article from the backpack 1, it becomes easier to know at which position the required article is stored. For example, it is possible to quickly take out the required article without rummaging through the inside of the backpack 1. Therefore, excellent handling performance can be obtained regardless of the characteristics of the user of the backpack 1.

[0060] <Method of using the backpack (procedure)> Hereinafter, an example of a method of using (procedure) for accommodating and taking out an article inside by opening the backpack 1 of the present embodiment shown in FIGS. 1, 2, and 6 as shown in the developed views of FIGS. 3 to 5 will be described in more detail (refer to the end views of FIGS. 7 to 10 as necessary).

[0061] First, operate the two sliders 62, 62 shown in FIGS. 2 and 6 and move them to both ends of the fastener 6 (element 61), that is, to the ends on the side of the one side wall 33, 43 that is disposed via the support piece 5 and exposed from the support piece 5.

[0062] Next, with the support piece 5 shown in FIG. 1 and the like as a fulcrum, the one storage body 3 and the other storage body 4 are separated from each other, so that as shown in FIGS. 3 to 5, the article storage portion 2 is in a double - leaf open state and its interior is opened. At this time, with the article storage portion 2 being in the double - leaf open state, the bag - shaped upper compartment storage member 7 and the lower compartment storage member 8 with the upper part opened are three - dimensionally deployed between the rear wall 30 and the front wall 40.

[0063] At the same time, two small pockets 74A, 74A and one small pocket 74B provided so as to be associated with the upper compartment storage member 7, and four small pockets 76 provided on the partition plate 75 are also opened with the upper part having a slight bulge.

[0064] Next, articles (not shown in the figure) are appropriately stored in the upper compartment storage member 7 and the lower compartment storage member 8 three - dimensionally deployed in the article storage portion 2. At this time, if necessary, articles (not shown in the figure) are also appropriately stored in a total of seven small pockets 74A, 74B, 76. Then, with the support piece 5 as a fulcrum, the article storage portion 2 in the double - leaf open state is closed, and in this state, the two sliders 62, 62 shown in FIGS. 2 and 6 are operated to close the fastener 6. Thereby, articles can be stored in the article storage portion 2 with excellent storage performance and handling performance, and the rucksack 1 can be carried without articles leaking out of the article storage portion 2.

[0065] On the other hand, when taking out an article (not shown in the figure) from the article storage portion 2, again, the two sliders 62, 62 shown in FIGS. 2 and 6 are operated and moved to both ends of the element 61 respectively, and while opening the interior of the article storage portion 2, the upper compartment storage member 7, the lower compartment storage member 8, and each small pocket 74A, 74B, 76 are deployed. Thereby, the articles stored in each part can be confirmed with good visibility and the articles can be taken out with good handling performance.

[0066] <Function and effect> As described above, according to the backpack 1 of the present embodiment, since the bag-shaped upper compartment storage member 7 and the lower compartment storage member 8 that partition the article storage space 2A are provided, articles can be efficiently and stably stored in a plurality of storage locations, and excellent visibility can be ensured. In addition, since the upper compartment storage member 7 and the lower compartment storage member 8 can limit the opening degree between one storage body 3 and the other storage body 4, when taking in and out articles, it is possible to suppress the posture of the backpack 1 from becoming unstable or the articles from popping out, and excellent handleability is ensured. Also, when the article storage section 2 is opened like a double door, since the upper compartment storage member 7 and the lower compartment storage member 8 can be three-dimensionally deployed, articles can be stored more efficiently, and it becomes excellent in usability when taking in and out articles. On the other hand, when the article storage section is closed, since the upper compartment storage member 7 and the lower compartment storage member 8 can be folded and accommodated in the article storage space 2A, it is possible to store them compactly and beautifully.

[0067] Furthermore, according to the backpack 1 of the present embodiment, by providing the upper compartment storage member 7 and the lower compartment storage member 8 that are three-dimensionally deployed inside the article storage section 2 as described above, for example, it is possible to avoid inconveniences such as those existing near the bottom inside a normal backpack not being visible. As a result, regardless of the characteristics of the user of the backpack 1, for example, because the target article was hidden in the shade inside the backpack and was difficult for the user to visually recognize, it took a very long time to find it, or it became necessary to take out all the articles inside the backpack and search, etc. Such situations can be prevented as much as possible.

[0068] Therefore, it is possible to realize a backpack 1 that can efficiently and stably store articles inside, can easily visually recognize the stored articles, is easy to take in and out articles, and is excellent in storage performance, visibility, and handleability.
