Description

[Technical field]

[0001] The present disclosure relates to a backpack, and more particularly to a backpack that allows a user to take in and out items at chest level without having to lower the backpack to the floor when it is worn on the back. [Background technology]

[0002] When wearing a backpack, there are times when you want to take something in or out of the backpack. Usually, you do this by removing the backpack from your shoulder and opening the top of the backpack, but in cases where you cannot place the backpack on the ground, or when you want to take something out immediately at a ticket counter, or when you want to take something out on a train without bothering other passengers, it can be difficult with a conventional backpack that requires you to take it off your back.

[0003] To deal with such a situation, Document 1 discloses a method for holding a backpack in front of the user's chest to allow items to be put in and taken out without having to take the backpack off the user's back.

[0004] The backpack is equipped with a backpack body for storing luggage, a pair of left and right shoulder straps attached to the backpack body, and a neck strap attached to the upper part of the backpack body and hung on the back of the neck of the user, the distance between the backpack body and the part where the neck strap abuts against the back of the neck can be adjusted. By taking out the neck strap attached to the backpack and hanging it around the neck, the backpack can be rotated around the neck and placed in front of the user, making it possible to take out luggage from the bag part at the front of the body. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2020-124465 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, with the backpack in Reference 1, when switching from a back-carrying position to a front-carrying position, the neck strap must be removed from behind the neck without being visible, which is troublesome. Furthermore, the neck strap and storage space are required, which adds volume and weight to the backpack itself.

[0007] The present disclosure has been made in consideration of the above circumstances, and its main object is to provide a backpack that can solve the above problems. [Means for solving the problem]

[0008] In the backpack of the present disclosure, either the left or right side of the backpack is a first half having a first shoulder belt, and the other side is a second half having a second shoulder belt, the first shoulder belt being composed of a first upper strap and a first lower strap, each of which has one end fixed to the backpack body, a first upper connecting part being attached to the end of the first upper strap, a first lower connecting part being attached to the end of the first lower strap, and an auxiliary connecting part being attached to the second half, and the first upper connecting part being detachably connectable to either the first lower connecting part or the auxiliary connecting part. Effect of the Invention

[0009] According to the backpack of the present disclosure, when the backpack is worn on the back, the upper strap of one of the shoulder belts can be removed and connected to an auxiliary strap attached to the other side of the backpack, forming a strap loop that encircles the periphery of the body. This loop can be used to wrap the backpack around the body, which has the effect of allowing the backpack to be easily placed on the front of the back and easily returned to a position where it can be worn again.

[0010] In addition, because it is a backpack with a simple structure with only the connecting parts added, there is an advantage that the weight and volume are not increased much while providing the above-mentioned functions. In addition, since the connecting parts can be attached and detached in a visible state, it is possible to put the backpack on the front in a short time. [Brief description of the drawings]

[Figure 6] FIG. 1 is a front view of the front side of a backpack according to one embodiment of the present disclosure. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Preferred embodiments of the present disclosure will be described below with reference to the drawings. Note that the following embodiments are merely examples of configurations and methods for embodying the technical ideas of the present disclosure, and the technical ideas of the present disclosure are not limited to those described below. The technical ideas of the present disclosure can be modified in various ways within the technical scope described in the claims.

[0013] In the following, the side of the backpack body 2 that contacts the back is called the backpack back side, and the opposite side is called the backpack front side. The backpack is composed of a backpack body having a storage section and shoulder straps, etc., which are sometimes treated as a single unit, and in the following, the backpack as a whole and the backpack body are sometimes referred to as the backpack without distinguishing between them. In addition, the connecting parts that detachably connect the straps are shown in the figures as male and female buckle types, but the gist of this disclosure is not affected even if other types of connecting parts such as snap hooks or spring hooks are used, or if the male and female types are reversed.

[0014] In addition, in this description, since it is necessary to divide the backpack into two parts, left and right, and to specify and explain the parts attached to each side, for convenience, one of the left and right sides of the backpack is designated as the first half part, and the other is designated as the second half part, and the parts belonging to the first half part are labeled as the first half part, and the parts belonging to the second half part are labeled as the second half part. In the description of the figures, the first half part is designated as the right side, and the second half part is designated as the left side, in order to make it easier to refer to the figures. The right side corresponds to the right side for the user. As described above, the left and right sides are distinguished according to the drawings, but the left and right sides of the actual backpack are not regulated.

[0015] Fig. 1 is a front view of the backpack surface of an example of a backpack 1 according to the present embodiment. In Fig. 1, the half of the backpack that is on the right side of the user when carrying the backpack main body 2 is referred to as the first half, and the left half as the second half, which will be described below.

[0016] The first shoulder belt 5 attached to the first half of the backpack body 2 on the back surface is composed of a first upper strap 11 and a first lower strap 13 connected by a removable connecting part. One end of the first upper strap 11 is fixed to the upper part of the first half of the backpack body 2, and the other end is attached to a first upper connecting part 12. One end of the first lower strap 13 is fixed to the bottom of the first half of the backpack body 2, and the other end is attached to a first lower connecting part 14. These straps may be attached to the main body by sewing thread or adhesive, or may be fixed via a removable part such as a hook.

[0017] Similarly, the second shoulder belt 6 attached to the second half may be configured by connecting a second upper strap 31 and a second lower strap 33 with a detachable connecting part. One end of the second upper strap 31 is fixed to the upper part of the second half of the backpack body 2, and the other end is attached to a second upper connecting part 32. One end of the second lower strap 33 is fixed to the bottom of the second half of the backpack body 2, and the other end is attached to a second lower connecting part 34. In the example of FIG. 1, the second shoulder belt 6 has the same configuration as the first shoulder belt 5, but in the present disclosure, the second shoulder belt 6 does not necessarily have to be a combination of two straps connected with a connecting part, and may not have a connecting mechanism.

[0018] The first upper strap 11 and the second upper strap 31 are provided with a first adjuster 9 and a second adjuster 10, respectively, so that the shoulder belt length can be adjusted. In the example of Fig. 1, the adjuster is attached to the upper strap side, but the adjuster may be attached to the lower strap side to adjust the shoulder belt length. In other words, the adjustment mechanism may be located anywhere on the shoulder belt.

[0019] Meanwhile, the lower auxiliary connecting part 24 is fixed near the corners of the bottom and side of the lower part of the second half side of the backpack 1 via the lower auxiliary strap 23. The lower auxiliary connecting part 24 may be fixed directly without the lower auxiliary strap 23. The lower auxiliary connecting part 24 has a function of being detachably connected to the first upper connecting part 12. When the first upper connecting part 12 of the first half part is connected to the lower auxiliary connecting part 24 of the second half part, a strap loop is formed that surrounds the periphery of the user's body. Since the backpack can be swung around the body using this loop, the user can easily rotate the backpack 1 around the body in the cross-body direction and carry the backpack 1 in front of the user. From the viewpoint of stability in the cross-body state, the fixing position of the lower auxiliary connecting part 24 in the absence of the lower auxiliary strap 23 or the lower auxiliary strap is preferably near the corners of the bottom and side of the second half part.

[0020] In addition, an upper auxiliary connecting part 22 is fixed near the upper end of the second half side of the backpack 1 via an upper auxiliary strap 21. The upper auxiliary connecting part 22 may be fixed directly without using the upper auxiliary strap 21. The upper auxiliary connecting part 22 has a function of being detachably connected to the first upper connecting part 12. When the first upper connecting part 12 of the first half part and the upper auxiliary connecting part 22 of the second half part are connected, a loop of the first upper strap 11 is formed around the neck, and the user can easily carry the backpack in front of the body without taking off the backpack 1 while hanging it around the neck. From the viewpoint of stability of hanging it around the neck, the fixing position of the upper auxiliary strap 21 or the upper auxiliary connecting part 22 when there is no upper auxiliary strap is preferably near the upper end of the second half of the backpack body 2.

[0021] In FIG. 1, the backpack 1 is shown equipped with the lower auxiliary connecting part 24 and the upper auxiliary connecting part 22, but the backpack 1 may be equipped with only one of them. In addition, the lower auxiliary connecting part 24 and the upper auxiliary connecting part 22 are shown only in the second half, but they may be on both sides of the first half and the second half. In other words, the form is a combination of a case where one side is considered as the first side and a case where the other side is considered as the first side. If both sides are provided with the functions of the present disclosure, the rotation of the backpack 1 for carrying in front can be selected either clockwise or counterclockwise, and there is also the advantage that the opening and closing direction of the zipper when taking out an item can be adjusted for right-handed and left-handed people.

[0022] The lower auxiliary strap 23, or the lower auxiliary connecting part 24 when there is no lower auxiliary strap, may be attached to the backpack body 2 or on the second shoulder belt, provided that it is near the corner of the bottom surface and side surface on the lower side of the second half. The upper auxiliary strap 21, or the upper auxiliary connecting part 22 when there is no upper auxiliary strap, may be attached to the backpack body 2 or on the second shoulder belt, provided that it is near the upper end of the second half. The fixing of these parts may be firmly fixed with sewing thread or adhesive, or may be in a detachable form via a connecting part such as a buckle or spring hook. If it is in a detachable form, the auxiliary strap can be removed when it is not needed, and the backpack can be used as a conventional backpack.

[0023] 4(a) and 4(b) are front views of the back side of an example of the backpack 1 for explaining the holding connection part 36. The holding connection part 36 is a holding part installed for the purpose of fixing the lower auxiliary strap 23 when the lower auxiliary strap 23 is not in use when the lower auxiliary strap 23 is long, and is attached to the second half. FIG. 4(a) shows a state in which the holding connection part 36 is fixed to the holding connection part 36 via the lower auxiliary connection part 24 when the lower auxiliary strap 23 is not in use, and FIG. 4(b) shows a state in which the lower auxiliary strap 23 is removed from the holding connection part 36 when the lower auxiliary strap 23 is in use. When the lower auxiliary strap 23 is not in use, the lower auxiliary strap 23 does not hang down and does not get in the way when walking with the backpack on.

[0024] The holding connection part 36 is attached to the holding adjuster 37 via the holding strap 35 so that it can be fixed at any position on the second shoulder belt 6. The holding strap 35 may be fixed at any position on the second shoulder belt 6 by other methods such as a hook without using an adjuster.

[0025] Also, the holding connection part 36 may be attached directly onto the second upper strap 31. In that case, the holding strap is eliminated, resulting in a simpler structure. The holding connection part 36 may be provided with a mechanism for changing its position on the second shoulder belt 6.

[0026] Figures 2(a) to (c) are front views of the backpack 1 when worn, explaining how to use the backpack 1. The figures also show only the backpack, with the user made transparent. Figures 3(a) to (c) show the front view of the backpack 1 when worn in the respective states of Figures 2(a) to (c).

[0027] 2(a) to (c) are different from Fig. 1 in that they show a backpack with no connecting parts on the second shoulder belt 6, because a simple example was chosen that does not impede the explanation of the present disclosure. All other parts and components are the same as those in Fig. 1.

[0028] FIG. 2(a) shows the state of the backpack in normal use. The user puts the backpack 1 on his / her shoulders by hanging the two shoulder straps on the left and right. FIG. 2(b) shows the state in which the first upper strap 11 is removed from the first lower connecting part 14 and connected to the lower auxiliary connecting part 24. If the connecting part used is a buckle or the like, it can be easily removed or attached with one push. Note that, until the first upper strap 11 is removed from the first lower connecting part 14 and connected to the lower auxiliary connecting part 24, the backpack 1 is supported by the left shoulder strap, so it will not fall. The first upper strap 11 connected to the lower auxiliary connecting part 24 changes into a loop-shaped cross-body belt that is hung from the shoulder around the body. When the backpack 1 is turned around the body in the cross-body direction, the backpack 1 is placed on the front.

[0029] Figure 3(b) is a front view of the backpack 1 in the state of Figure 2(b) placed on the front. When placed on the front, both hands are free to use, making it easy to take in and out the contents.

[0030] While rotating the backpack 1 in front of the body in the cross-body state, the second shoulder belt 6 remains connected, but as shown in Fig. 3(b), the second shoulder belt 6 comes off the shoulder and hangs on the arm during rotation, so there is almost no hindrance to taking in and out of items when rotating or placing in front. If this bothers you, you can attach a detachable connector as shown in Fig. 1 to the second shoulder belt 6 and disconnect the second shoulder belt 6 just before rotating.

[0031] The ease of rotation of the backpack body 2 in the cross-body state also depends on the length of the lower auxiliary strap 23, so this may be adjusted appropriately. For this reason, an adjuster or the like may be attached to the lower auxiliary strap 23 so that the length can be adjusted.

[0032] FIG. 2(c) shows the state in which the first upper strap 11, which has been detached from the first lower connecting part 14, is connected to the upper auxiliary connecting part 22 in order to place the backpack 1 in front of the user, from the state shown in FIG. 2(a). The first upper strap 11 connected to the upper auxiliary connecting part 22 becomes a loop-shaped belt around the neck, and the backpack can be worn from the back to the front of the body without taking off the backpack. FIG. 3(c) shows the front view of the backpack 1 hung in front of the user. When the backpack is hung in front of the user, the backpack 1 is hung around the neck, the top end of the backpack 1 faces upward, and both hands are free to use, making it easy to take in and out of the contents. If the connecting part is a buckle or the like, it can be easily removed or attached with a single push.

[0033] As another method of placing the backpack 1 in front, the first upper strap 11 detached from the first lower connecting part 14 can be held in one hand while the backpack 1 is wrapped around the body, and after the backpack 1 is placed in front of the body, the first upper strap 11 being held in the hand can be connected to the upper auxiliary connecting part 22. In this case, the front view of the backpack 1 placed in front is as shown in FIG. 3(c).

[0034] 5 and 6 are front views of the surface of the backpack to explain how to access the storage section of backpack body 2 and the storage section of accessory case 3 attached to the surface of the backpack and take items in and out.

[0035] In Fig. 5, openings that communicate with the storage compartment of the backpack body 2 are formed on the top and side surfaces. An upper zipper 7a and a side zipper 8a are attached to the openings, respectively, and opening and closing these opens and closes the storage space of the backpack body 2. In this way, since the storage compartment can be accessed from two directions, when placed in front as in Fig. 3(b), it can be easily opened and closed by operating the side zipper 8a, and when placed in front as in Fig. 3(c), it can be easily opened and closed by operating the upper zipper 7a.

[0036] The opening at the top is not limited to being opened and closed by a zipper, but may be opened and closed by a clasp, a drawstring, a hook and loop fastener, or the like.

[0037] In Fig. 5, the front side of the backpack 1 is provided with a storage compartment 3 for storing small items, and an inclined zipper 7c is installed at an angle at the opening of the storage compartment 3. When the backpack body 2 on the back side is rotated in a cross-body direction as shown in Fig. 3(b) and placed in front, the opening is inclined, so that the opening of the storage compartment 3 faces upward, allowing items to be put in and taken out of the storage compartment 3 without dropping them.

[0038] The inclination angle of the inclined zipper 7c at the opening of the accessory compartment 3 described above may be set appropriately according to the shape and size of the backpack body 2 and the length of the auxiliary strap. From the standpoint of ease of access and storage capacity, it is desirable for the inclination to be within the range of 20° to 70° with respect to a line parallel to the bottom surface of the backpack 1.

[0039] In addition, the opening and closing of the accessory case 3 is preferably done by a zipper that closes without any gaps, but it may also be done by a clasp, a closing string, a buckle, or the like.

[0040] The accessory case 3 in Fig. 6 has zippers on the top and sides for opening and closing. Either zipper can be used to put items in and take items out of the storage compartment of the accessory case 3. Since the storage compartment can be accessed from two directions, when placed in front as in Fig. 3(b), it can be easily opened and closed by operating the side zipper 8b, and when placed in front as in Fig. 3(c), it can be easily opened and closed by operating the upper zipper 7b.

[0041] The length and installation position of the upper zipper 7 and the side zipper 8 described above are desirably set in consideration of the ease of putting things in and taking things out according to the size of the backpack 1 and the contents. The upper zipper 7 and the side zipper 8 are installed in a roughly horizontal direction and a roughly vertical direction, respectively, but depending on the design of the backpack 1, they may be inclined horizontally or vertically. In addition, the upper zipper 7 may be extended to the side and wrapped around, or the side zipper 8 may be wrapped around the upper side. If the upper zipper 7 and the side zipper are installed in a parallel offset position, parts of the two zippers are aligned parallel to each other and do not overlap, so that the wraparound length can be freely set, and the effect of being able to take the length of the zipper that allows items to be put in and taken out more smoothly is achieved.

[0042] The zipper cover 40 is a cover that is attached so as to cover the zipper. When the zipper cover 40 is attached to the side zipper 8 that is used less frequently, the side zipper 8 is usually hidden, so that items can be put in and taken out of the upper opening without being aware of the presence of the side zipper 8. The zipper cover 40 may be made of a transparent or opaque material, and may be made of cloth, leather, resin, etc.
