Description

[Technical field]

[0001] The present invention relates to a backpack bag, and in particular to a backpack bag that stabilizes the center of gravity of luggage and reduces the burden on the body even when the luggage contained in the backpack bag body is heavy. [Background technology]

[0002] Backpacks, backpacks, school bags, and other backpacks are widely used as tools for carrying heavy and bulky luggage. These are worn on the user's back via a pair of shoulder straps attached to the backpack body. Backpacks are used for long-distance travel, hiking, mountain climbing, commuting to school, commuting to work, and so on. By the way, the weight of the backpacks that elementary school students carry to school has become a serious problem, causing health problems for children. Various research and development efforts are being made to reduce this physical burden.

[0003] In conventional school bags, when textbooks, notebooks, and other items are stored in the main storage section and a user such as an elementary school student carries the bag on their back and walks or runs, the stored items tend to rattle inside the main storage section or get damaged by hitting the walls that make up the main storage section, because the stored items are not fixed inside the main storage section. In particular, when the amount of stored items is small, the items move around a lot inside the main storage section, causing a lot of rattling, and often causing damage to the stored items.

[0004] Patent Document 1 discloses a pressure plate sized to fit within the main storage compartment of a school bag, with front support plates on both side ends having at least one bent portion that elastically returns to its original angle, protruding toward the front wall of the main storage compartment, and further with rear support plates on both side ends of the pressure plate, also having at least one bent portion that elastically returns to its original angle, protruding toward the rear wall of the main storage compartment.

[0005] Patent Document 2 discloses a school bag that has an inner basket inside so that the weight of luggage is concentrated at the top of the school bag body rather than at the bottom. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2008-259608 A [Patent Document 2] JP 2022-172484 A Summary of the Invention [Problem to be solved by the invention]

[0007] If the backpack is heavy, the user will naturally feel it is heavy. Also, if the center of gravity of the backpack is far from the back, the user will feel it is heavy. Furthermore, if the center of gravity of the backpack is low, the user will feel it is heavy. Therefore, when the baggage in the backpack is moved toward the back of the user, the backpack feels relatively light. Similarly, when the baggage in the backpack is moved toward the upper side, the backpack feels relatively light. Therefore, if you feel that the backpack is heavy, you can reduce the feeling of weight by moving the luggage inside the backpack closer to your back or higher up.

[0008] However, with the backpack bag described in Patent Document 1, the divider cannot be adjusted once the backpack bag is worn, and the center of gravity cannot be raised or moved closer to the back. This poses the problem that the divider must be adjusted before the backpack bag is worn. Therefore, with the backpack bag described in Patent Document 1, the baggage, etc. is stored in a position away from the user inside the backpack bag, so that the center of gravity of the baggage is located away from the user, and if the baggage feels heavier, it is necessary to remove the backpack bag from the user's back and adjust it, which is troublesome. In particular, school bags are used by elementary school students, and it is troublesome and practically difficult for elementary school students to remove the school bag from their back and adjust it.

[0009] Furthermore, the school bag described in Patent Document 2 has a problem in that there is a limit to the amount of luggage that can be stored.

[0010] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a backpack bag that stabilizes the center of gravity of luggage and reduces the burden on the body even when the luggage contained in the backpack bag body is heavy. [Means for solving the problem]

[0011] One aspect of the present invention for solving the above problems is a backpack bag having a backpack bag body for storing luggage, a pair of left and right shoulder belts attached to the sides of the backpack bag body that contact the back, and a partition within the backpack bag body for separating the luggage, wherein the partition can be moved by a moving means within the backpack bag body by operating from outside the backpack bag body.

[0012] In this aspect, the partition can be moved within the backpack bag body by operating it from outside the backpack bag body, so the partition can be moved while the backpack bag is being worn, which is less troublesome than having to take the backpack bag off before operating it.

[0013] A preferred aspect is a backpack bag in which the partition can be moved to the back side and / or shoulder side of the user by operation of the user carrying the backpack bag.

[0014] According to this configuration, the user can move the divider while wearing the backpack bag, which is less troublesome than having to take the backpack bag off before operating it, and since the divider moves to the back and / or shoulder side of the user, the luggage fits closely to the back, making the user feel that the weight of the backpack bag is lighter.When the divider moves to the shoulder side, the center of gravity of the luggage rises, making the user feel that the weight of the backpack bag is lighter.

[0015] A preferred aspect is a backpack bag having a backpack bag body for storing luggage, a pair of left and right shoulder belts attached to the surface of the backpack bag body that contacts the user's back, a partition within the backpack bag body for separating the luggage, and a moving means that is connected to the partition within the backpack bag body and moves the partition within the backpack bag body by operating from outside the backpack bag body.

[0016] With this configuration, the user can move the partition while still wearing the backpack bag, which is less hassle than having to take the backpack bag off and then operate it.In addition, because the partition moves to the back of the user, the luggage is placed in close contact with the back, making it feel as if the weight of the backpack bag is reduced.

[0017] A preferred aspect is a backpack bag in which the moving means is a cord connected to at least the upper end side of the partition, and the partition moves toward the user's back and / or shoulder when the user carrying the backpack bag pulls the cord.

[0018] Here, the cord-like member is a general term for flexible and long members such as belts, strings, wires, etc. According to this aspect, when a user of the backpack bag pulls the cord-like member while wearing the backpack bag, the partition moves toward the user's back and / or shoulders, allowing the user to feel the weight of the luggage in the backpack bag.

[0019] A preferred aspect is a backpack bag in which the moving means is a cord connected to at least the upper end of a side of the partition, and the partition moves toward the user's back and / or shoulder when the user carrying the backpack bag pulls the cord.

[0020] Since the moving means is a cord connected to at least the upper end of the side of the partition, the cord does not get in the way when the backpack bag is taken off and the baggage inside the backpack bag is removed.

[0021] In a preferred embodiment, the moving means is a rope, which is located on a backpack and passes through a shoulder belt.

[0022] According to this aspect, the cord-like member is inserted inside the shoulder belt, so that the backpack bag has a neat appearance.

[0023] A preferred aspect is a backpack bag in which the moving means is a cord, the shoulder belt has an opening, the cord is inserted through the shoulder belt, one end of the cord is exposed from the opening in the shoulder belt, and the partition moves toward the user's back and / or shoulder by pulling the exposed cord.

[0024] According to this aspect, the moving means is a cord-like member that is inserted through the shoulder belt, one end of the cord-like member is exposed from the shoulder belt, and the partition is located on the backpack bag so that pulling the exposed cord-like member moves the partition to the user's back and / or shoulder, allowing the user to pull the belt while wearing the backpack bag and bring the center of gravity of the luggage to the back and / or shoulder.

[0025] A preferred aspect is a backpack bag in which the partition is not fixed to the backpack bag body, the moving means is a rope-like body, one end of the rope-like body is connected to at least the upper end of the partition, and the other end of the rope-like body is connected to the lower end of the partition.

[0026] According to this aspect, since the partition is not fixed to the backpack bag body, when the user of the backpack bag pulls the cord-like body, the partition reliably moves above and toward the back of the user, making the user feel that the luggage in the backpack bag is lighter.

[0027] A preferred aspect is a backpack bag in which the moving means is a cord connected to at least the upper end side of the partition, the lower end of the partition is fixed to the bottom inside the backpack bag body, and the partition tilts toward the user's back and / or shoulders when a user carrying the backpack bag pulls the cord.

[0028] According to this aspect, the lower end of the partition is fixed to the bottom inside the backpack body, so that the partition can be reliably tilted toward the back and / or shoulders by pulling the cord-like body.

[0029] A preferred aspect is a backpack bag in which the partition is plate-shaped, the lower end of the partition is fixed to the bottom of the backpack bag body, and the partition is positioned approximately in the center of the backpack bag body in the depth direction.

[0030] According to this aspect, the lower end of the partition is fixed to the bottom inside the backpack bag body, so that pulling the belt can reliably tilt the partition toward the back. Also, since the partition is positioned approximately in the center of the depth of the backpack bag, the luggage in the backpack bag can be moved closer to the user's back, and the backpack bag body can be fitted closely against the user's back.

[0031] A preferred aspect is a backpack bag in which the moving means is a cord-like body, and when the user of the backpack bag pulls the cord-like body, the partition moves toward the user's back and / or shoulder, thereby shifting the load center of gravity of the luggage toward the user's back and / or shoulder.

[0032] According to this aspect, the moving means is a cord-like body, and when the user of the backpack bag pulls the cord-like body, the partition moves toward the user's back and / or shoulders, thereby shifting the center of gravity of the load of the luggage toward the user's back and / or shoulders.By shifting the center of gravity of the load of the luggage toward the user's back and / or shoulders, the user can feel the luggage in the backpack bag as lighter.

[0033] A preferred aspect is a backpack bag in which the moving means is a cord, the shoulder belt has an opening, the cord is inserted through the shoulder belt, one end of the cord is exposed from the opening in the shoulder belt, the partition moves to the back and / or shoulder of the user by pulling the exposed cord, and the exposed cord can be fixed to another member by a fixing means.

[0034] According to this aspect, the moving means is a cord, the shoulder belt has an opening, the cord is inserted through the shoulder belt, one end of the cord is exposed from the opening of the shoulder belt, and one end of the exposed pair of left and right belts can be fixed to another member by a fastener, a hook-and-loop fastener, or other fixing means. In the backpack bag of this aspect, the partition moves to the back and / or shoulder of the user by pulling at least one of the pair of exposed left and right cords. According to this aspect, after the backpack bag is put on the back, the cord can be pulled and further fixed, so that the state in which the partition moves to the back of the user can be maintained. Therefore, the user can continuously feel the luggage in the backpack bag as being lighter.

[0035] A preferred aspect is a backpack bag in which the moving means is a pair of left and right cord-like bodies, the shoulder belt has an opening, the cord-like bodies are inserted through the shoulder belt, one end of the cord-like bodies is exposed from the opening in the shoulder belt, and by pulling at least one of the exposed pair of left and right cord-like bodies, the partition moves toward the user's back and / or shoulder, and the exposed pair of left and right cord-like bodies can be connected to each other by a connecting means.

[0036] In this type of backpack bag, the cord passes through the shoulder belt, and one end of the cord is exposed from the shoulder belt. Therefore, after the backpack bag is put on, the partition moves toward the user's back by pulling the exposed cord. In this type of backpack bag, the cords can be freely connected and disconnected by fasteners, hook-and-loop fasteners, or other connecting means, so that the partition can be maintained in a state where it moves toward the user's back by connecting the exposed cords. Therefore, the user can continuously feel that the luggage in the backpack bag is lighter.

[0037] A preferred aspect is a backpack bag in which the moving means is a pair of left and right cords, the backpack bag body has an opening on the side of the user's back, the cords pass through the backpack bag body and are exposed from the opening on the side that contacts the user's back, and by pulling the exposed cords, the partition moves to the user's back and / or shoulder side, and the exposed pair of left and right cords can be connected to each other by a connecting means.

[0038] According to this aspect, the appearance of the backpack bag is neater, and when the user of the backpack bag pulls on the cord-like body, the partition can be reliably moved and fixed above the user and toward the back and / or shoulders, allowing the user to continue to feel that the luggage in the backpack bag is lighter even while moving.

[0039] A preferred aspect is a backpack bag in which the moving means is a pair of left and right cords, the backpack bag body has an opening on the back side of the user, the ends of the cords are connected to the left and right side surfaces of the partition approximately at the center of the height of the partition, the cords pass through the backpack bag body and are exposed from the opening on the side that contacts the user's back, the exposed cords are pulled to move the partition toward the user's back and / or shoulder, and the other ends of the exposed pair of left and right cords can be connected to each other by a connecting means.

[0040] According to this aspect, the partition reliably moves to the back and / or shoulders when the user of the backpack pulls the cord. The cords are then connected together to maintain the partition in the back of the user. This allows the user to continually feel that the luggage inside the backpack is lighter.

[0041] In a preferred aspect, the partition is at least partially easily deformable and is fixed to a surface of the backpack bag body facing the back of a user.

[0042] According to this aspect, at least a portion of the partition is easily deformable, so that the partition can be easily moved toward the back side, and the center of gravity can also be easily moved toward the back side and / or shoulder side. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0045] The backpack bag according to the embodiment of the present invention will be further described below. As shown in FIG. 1, the backpack bag 1 of this embodiment is a hollow bag with a bottom made of a woven synthetic fiber fabric, with a luggage storage space formed inside and a luggage storage opening (not shown) at the top. The surface 5 of the backpack bag body 41 that contacts the user's back is formed approximately flat to match the user's back, and cushioning material to enhance the contact feeling with the back is appropriately arranged on the entire surface or part of the surface. A pair of shoulder straps 2, 3 are arranged on both sides of the surface 5 of the backpack bag body 41 that contacts the user's back. The backpack bag body 41 has a partition 4 that separates luggage. The partition 4 has rigidity and is not easily deformed. The shoulder straps 2, 3 are formed by sewing nylon fabric, and a cushioning material such as sponge can be inserted inside to provide cushioning properties.

[0046] Example 1 Fig. 2 is a side cross-sectional view of the backpack bag 1 of this embodiment, and Fig. 3 is a front view of the backpack bag 1. In the backpack bag 1 of this embodiment, as shown in Fig. 8(a), one ends of belts 7 and 8, which are cord-like bodies (hereinafter referred to as belts), are connected to the upper end 6 of the partition 4. The other ends 31 and 32 of the belts 7 and 8 are connected to the lower end 13 of the partition 4. In the backpack bag 1 of this embodiment, the partition 4 inside the backpack bag body 41 can be moved by operating the belts 7, 8 from outside the backpack bag body 41. In this embodiment, the belts 7 and 8 are moving means for moving the partition 4 inside the backpack bag body 41 by operating from outside the backpack bag body 41. The material of the belts 7 and 8 may be the same as that of the shoulder belts 2 and 3. Moreover, the belts 7 and 8 may be replaced by strings, wires, etc.

[0047] The belts 7 and 8 each have an upper belt 57, 59 and a lower belt 58, 64, which are connected to each other by a buckle 55 (fastener). That is, the belts 7 and 8 each have one end of the upper belt 57, 59 and one end of the lower belt 58, 64 connected to each other by the buckle 55. In this embodiment, the other end of the upper belt 57, 59 is fixed to the upper end 6 of the partition 4. The other ends 31, 32 of the lower belt 58, 64 are fixed to the lower end 13 of the partition 4. As described above, the belts 7 and 8 each have one end of the upper belt 57, 59 and one end of the lower belt 58, 64 connected to each other by the buckle 55, and one end of the upper belt 57, 59 protrudes from the buckle 55.

[0048] The structure and function of the buckle 55 are known. The buckle 55 is composed of a base 60 and a lid 61 as shown in Figs. 4(a) and (b), and the lid 61 is rotatably attached to the base 60. The lower belts 58 and 64 are attached to the base 60 by folding back their ends, and the front side of the base 60 has an opening 62. The upper belts 57 and 59 are inserted between the base 60 and the lid 61, and when an appropriate length is pulled out from the buckle 55, the lid 61 is closed and fixed, so that the upper belts 57 and 59 are connected to the lower belts 58 and 64 and can be maintained in this state. The partition 4 can be moved by pulling the upper belts 57 and 59. Then, by closing the lid 61 while pulling the upper belts 57 and 59, the upper belts 57 and 59 are fixed to the lower belts 58 and 64 while maintaining the pulled-out state.

[0049] The belts 7, 8 are inserted through the pair of left and right shoulder belts 2, 3. The middle parts of the belts 7, 8 are exposed from openings 65, 67 of the shoulder belts 2, 3. That is, as shown in Fig. 3, the vicinity of the buckle 55 which is the joint between the upper belts 57, 59 and the lower belts 58, 64 is exposed from the openings 65, 67 of the shoulder belts 2, 3. Therefore, the ends (free ends) of the upper belts 57, 59 are exposed from the openings 65, 67 of the shoulder belts 2, 3 at the upper part outside the backpack bag body 41. As described above, the upper belts 57, 59 and the lower belts 58, 64 are connected by the buckle 55.

[0050] As described above, the other ends 31, 32 of the belts 7, 8 (the other ends of the lower belts 58, 64) are connected to the lower end 13 of the partition 4. Furthermore, the lower end 13 of the partition 4 is fixed to the bottom A inside the backpack bag main body 41. The lower end 13 of the partition 4 and the bottom A inside the backpack bag main body 41 are bonded together by sewing or with an adhesive.

[0051] In addition, one end 9, 10 of the upper belts 57, 59 is pulled out from the buckle 55, and the user of the backpack bag can pull one end 9, 10 of the upper belts 57, 59 in the direction 11 as shown in Fig. 5, thereby moving the partition 4 connected to the belts 7, 8 towards the user's back. This allows the partition 4 to be moved while the backpack bag 1 is still being worn, which is less troublesome than having to operate it after taking the backpack bag 1 off.

[0052] FIG. 7 shows a state where the user pulls on the exposed ends 9, 10 of the upper belts 57, 59 of the backpack bag 1. FIG. 6 shows a state before pulling on the ends 9, 10 of the upper belts 57, 59. The baggage 15 is stored in the backpack bag body 41. However, there is a gap between the baggage 15 and the inner wall 17 of the surface 5 that contacts the user's back, and when the user walks while carrying the backpack bag 1, the baggage 15 swings around in the backpack bag body 41. However, when the ends 9, 10 of the upper belts 57, 59 are pulled and the partition 4 is tilted toward the user's back as shown in FIG. 6, the baggage 15 is fixed between the partition 4 and the inner wall 17, and the baggage 15 does not swing around. In addition, when the partition 4 is tilted toward the user's back, the center of gravity of the load of the baggage 15 before tilting becomes the center of gravity of the load B' after tilting, and the center of gravity of the load of the baggage 15 approaches the user's back. Therefore, the baggage 15 will not swing about inside the backpack body 41, and the baggage 15 will not be damaged.

[0053] Furthermore, after pulling the ends 9, 10 of the upper belts 57, 59, the user holds the ends 9, 10 of the upper belts 57, 59 in a state in which they do not move any further, and then presses and fixes the upper belts 57, 59 with the lid portion 61 of the buckle 55. In this way, the luggage 15 is fixed between the partition 4 and the inner wall 17, and the luggage 15 remains fixed while the user is carrying the backpack bag 1 and moving, and the center of gravity of the load of the luggage 15 also remains close to the user's back and stable.

[0054] The partition 4 is plate-shaped and is disposed approximately in the center in the depth direction C of the backpack body 41. The material of the partition 4 is not particularly limited, but a lightweight synthetic resin plate, for example a foamed resin with a synthetic resin film laminated on both sides, is preferable because it is lightweight, strong, and durable. There is no problem in implementing the partition 4 using a plywood board or cardboard. Furthermore, the shape of the partition 4 is not particularly limited, and it may be a rectangular or circular plate. Furthermore, the side surface of the partition 4 and the inner surface of the backpack bag body 41 may be connected with a flexible member.

[0055] Example 2 In the above embodiment, as shown in Fig. 8(a), the belts 7 and 8 are attached to the upper side of the partition 4, but the present invention is not limited to this configuration. For example, as shown in Fig. 8(b), the belts 7 and 8 may be attached to the side of the partition 4. According to the second embodiment of the present invention, as shown in Fig. 8(b), the moving means are belts 7, 8 connected to at least the upper ends 6 of the sides 23, 26 of the partition 4, so that when the backpack bag 1 is taken off and the baggage 15 inside the backpack bag 1 is removed, the belts 7, 8 do not get in the way because the interval between them is wide. Fig. 8(a) is a diagram showing the state in which the belts 7, 8 are connected to the upper end 6 of the partition 4, but the interval G between the belts 7, 8 in Fig. 8(b) is clearly wider than the interval G' between the belts 7, 8 in Fig. 8(a).

[0056] Example 3 9(a) and 9(b), a guide 81 for the belts 7 and 8 is provided on the rear side of the partition 4 (opposite the user's back), and the belts 7 and 8 are not separate but are one piece, passing through the guide 81 provided on the rear side of the partition 4 and along the rear side of the partition 4. In this way, when the backpack bag 1 is taken off and the baggage 15 is removed from the backpack bag 1, the belts 7 and 8 are spaced apart from each other widely, so that the belts 7 and 8 do not get in the way. The space I between the belts 7 and 8 in FIG. 9(a) is clearly wider than G'.

[0057] Example 4 In the embodiment described above, the lower ends of the belts 7 and 8 are connected to the lower end 13 of the partition 4 , but the belts 7 and 8 do not have to be connected to the lower end 13 of the partition 4 . According to the third embodiment of the present invention, as shown in Fig. 10, inside the backpack bag body 41, one end of the belts 7, 8 is connected only to the upper end 6 of the partition 4. The belts 7, 8 are inserted through a pair of left and right shoulder belts 2, 3. One ends 9, 10 of the belts 7, 8 are exposed from openings 65, 67 of the shoulder belts 2, 3. The belts 7, 8 are not connected to the partition 4 except for the upper end 6 of the partition 4. One ends 9, 10 of the belts 7, 8 can be fixed to the shoulder belts 2, 3 by hook-and-loop fasteners (connecting means) 20.

[0058] In the backpack bag 1 of the fourth embodiment, as in the first embodiment, the user pulls one end 9, 10 of the belt in the direction 11 as shown in Fig. 4, and the partition 4 connected to the belts 7, 8 moves to the back side of the user. This allows the partition 4 to be moved while the backpack bag 1 is still being worn, which is less troublesome than having to operate the partition 4 after taking off the backpack bag 1.

[0059] Example 5 In the embodiment described above, the lower end 13 of the partition 4 is fixed to the bottom A inside the backpack bag body 41. However, the present invention is not limited to this configuration. In the fifth embodiment of the present invention, the lower part of the partition 4 is free from the backpack bag body 41, and the two are not connected to each other. That is, in the backpack bag 1, one end of the belts 7, 8 is connected to the upper end 6 of the partition 4 in the backpack bag body 41, and the other end of the belts 7, 8 is connected to the lower end 30 of the partition 4, as shown in FIG. 11, and the partition 4 is not fixed to the backpack bag body 41. Therefore, the movement of the partition 4 is influenced by the movement of the belts 7, 8. FIG. 12 shows a state in which the user pulls one end 9, 10 of the belt. The partition 4 moves toward the user's back and obliquely upward (direction D). In other words, since the partition 4 moves toward the user's shoulder (direction D), the center of gravity of the load of the luggage 15 before pulling the one end 9, 10 of the belt becomes the center of gravity of the load E' after pulling, and the center of gravity of the load of the luggage 15 approaches the shoulder of the user.

[0060] Example 6 In the sixth embodiment, the lower part of the partition 4 is connected to a surface 5 on the back side of the user inside the backpack body 41 . In the sixth embodiment, at least a portion of the partition 4 of the backpack bag 1 is easily deformable, and a lower portion of the partition 4 is fixed to a surface 5 on the back side of the user inside the backpack bag body 41 . As shown in Figs. 13 and 14, at least the bottom F of the partition 4 is bag-shaped, and one end 50 of the bottom F is connected to the surface 5 of the backpack body 41. The belts 7 and 8 are connected to the upper end 6 of the partition 4, and the shoulder belts 2 and 3 are inserted through the belts 7 and 8, which are exposed near the chest or abdomen of the user. Fig. 13 shows the user before pulling the belt ends 9 and 10, and Fig. 14 shows the user after pulling the belt ends 9 and 10. At this time, the baggage 15 and the center of gravity J of the load have moved to the upper side and toward the back of the user. Therefore, the user can feel the baggage 15 in the backpack 1 lighter. The material of the bottom F of the partition 4 may be the same material as the partition 4 but with a thinner thickness, or it may be the same material as the belts 7 and 8 or the shoulder belts 2 and 3.

[0061] Example 7 In the first embodiment described above, the posture of the partition 4 is maintained by fastening the upper belts 57, 59 to the lower belts 58, 64 with fasteners such as the buckle 55. In the fourth embodiment, the posture of the partition 4 is maintained by fastening the belts 7, 8 to other members such as the shoulder belts 2, 3 with a hook-and-loop fastener (connecting means) 20. In the seventh embodiment, the belts 7 and 8 are connected to each other by a connecting means, thereby maintaining the position of the partition 4. 15, in the seventh embodiment, one ends 9, 10 of the belts exposed from the openings 65, 67 of the shoulder belts 2, 3 are connected to each other by a hook-and-loop fastener 20 so as to be freely connected and detached. The means for enabling the connection and detachment is not limited to the hook-and-loop fastener 20, but may be a buckle.

[0062] Example 8 In all of the embodiments described above, the cord-like body is connected to the upper side of the partition 4, but the present invention is not limited to this configuration. In the eighth embodiment of the present invention, as shown in Fig. 16 and Fig. 17, the ends 21, 22 of a pair of left and right belts 7, 8 as means for moving the partition 4 are connected to the left and right side surfaces 23, 26 of the partition 4 at approximately the center in the height direction H of the partition 4, respectively, and the belts 7, 8 penetrate the backpack body 41 and are exposed from the openings 70, 71 on the side in contact with the user's back, and the partition 4 is moved to the user's back by pulling the other ends 24, 25 of the exposed belts, and after the partition 4 is moved, the other ends 24, 25 of the exposed pair of left and right belts 7, 8 are fixed to each other by the hook-and-loop fastener 20. In this way, the belts 7, 8 can be fixed to the chest or abdomen of the user while the backpack 1 is being carried on the user's back, so that even an elementary school student can easily operate it. In addition, the baggage in the backpack 1 can be continuously felt lighter while the user is carrying the backpack bag on his / her back and moving. In order to secure the pair of exposed left and right belts with the hook-and-loop fastener 20, the pair of exposed left and right belts must be long enough so that the belts can be secured to the chest or abdomen of the user.

[0063] Example 9 In addition, in another embodiment (ninth embodiment) of the present invention, as shown in FIG. 18, an auxiliary plate 90 is further provided on the surface side of the partition 4 of the backpack body 41, and a magnet 91 is provided at a location facing the partition 4. An iron piece 92 is provided on the surface of the partition 4 facing the auxiliary plate 90. By doing so, as shown in FIG. 18(b), the partition 4 is fixed to the auxiliary plate 90 before pulling the belts 7 and 8. Also, as shown in FIG. 18(a), when the user pulls the belts 7 and 8 to move and fix the partition 4, and then releases the fixation as shown in FIG. 18(b), the partition 4 moves by magnetic force and is fixed to the auxiliary plate 90, and the partition 4 returns to its original position. This makes it easier to take out the luggage 15. Here, an iron plate may be provided on the auxiliary plate 90 and a magnet may be provided on the partition 4, or both may be magnets.

[0064] Example 10 Furthermore, as in the tenth and eleventh embodiments shown in FIG. 19, the partition 4 and the belts 7, 8 may be detachable. In the tenth embodiment of the present invention, as shown in Fig. 19(a), the belts 7, 8 and the upper belts 57, 59 are connected by a known buckle 95. When one end 9, 10 of the belt is pulled to move the partition 4, the belts 7, 8 and the upper belts 57, 59 are connected by the buckle 95. When the backpack bag 1 is taken off and the baggage 15 inside the backpack bag 1 is removed, the connection of the buckle 95 is released. By doing so, the partition 4 can be easily returned to its original position, making it easier to remove the baggage 15.

[0065] Example 11 In an eleventh embodiment of the present invention, as shown in Fig. 19(b), hooks 97 are attached to the ends of the belts 7, 8, and a hole 96 for attaching the hook 97 is formed in the upper end 6 of the partition 4. When one end 9, 10 of the belt is pulled to move the partition 4, the hooks 97 of the belts 7, 8 are connected to the hole 96 of the partition 4 by the hook 97. When the backpack bag 1 is taken off and the baggage 15 inside the backpack bag 1 is to be removed, the hook 97 is removed from the hole 96. By doing so, the partition can be easily returned to its original position, making it easier to remove the baggage 15.
