[0001] The present invention relates to a bag that is used by hanging it on both shoulders such that two storage portions for storing luggage are arranged on the front side and the rear side of the body.

Background Art

[0002] Conventionally, as a bag for newspaper delivery, a bag (newspaper bag) that is hung on both shoulders and has a large capacity and a large opening for easy access has been used. As shown in Non-Patent Document 1, in this bag, storage portions are connected to both ends in the length direction of a yoke portion through which the head can be inserted, and the bag is worn such that the two storage portions are positioned in front of and behind the body by passing the head through the yoke portion. In recent years, due to its high design and convenience, it has been used as a general-purpose bag in which the items to be stored are not limited to newspapers.

[0003] Since the two storage portions are suspended from a yoke portion supported on both shoulders, for example, they may swing during walking, making the stored luggage feel heavy. In order to suppress such swinging, Patent Document 1 proposes a bag hung on both shoulders configured to connect both ends of the storage portion wound around the body with a fastener. Also, although it is a bag hung on one shoulder, a bag has been proposed in Patent Document 2 in which the upper portions of two storage portions arranged in front of and behind the body are connected by a shoulder strap, and the bottom sides of the two storage portions are connected by a waist belt.

Non-Patent Document 1

[0006] As described in Patent Document 1, if the two ends of the storage unit wrapped around the body are connected with fasteners, it may not be possible to connect them depending on the wearer's physique, or even if connected, the gap between the unit and the body may be too large to suppress swinging. On the other hand, as described in Patent Document 2, if the unit is connected with a waist belt, it can be adjusted to the wearer's physique, but there is a risk of the waist belt falling off or being lost when not being worn.

[0007] The purpose of this invention is to provide a bag that suppresses the shaking of the storage compartment and distributes the load of the storage compartment, thereby reducing the weight felt by the wearer. [Means for solving the problem]

[0008] The bag according to claim 1 is characterized by comprising: a first and second storage section in the shape of a gusseted bag; a rectangular yoke section to which the first and second storage sections are connected at both ends in the longitudinal direction, such that the first and second storage sections bulge out on the same side and the entrances of the first and second storage sections face each other, the yoke section having an opening in the center for passing the head through and being flexible; a pair of connecting belts extending from both sides of the bottom side of the first storage section; a pair of connecting receiving parts equipped at both ends of the yoke section in the width direction perpendicular to the longitudinal direction near the connection between the yoke section and the second storage section; and a pair of connecting insertion parts equipped on each pair of connecting belts, each having a length adjustment function, which connect the first storage section and the yoke section near the second storage section by being inserted into and fixed to the corresponding connecting receiving part.

[0009] With the above configuration, the bag can be worn so that the head passes through the opening of the yoke, the first storage compartment is positioned on the chest side, the second storage compartment is on the back side, and the yoke is supported by both shoulders. The first storage compartment and the yoke on the back can be connected by fixing the connecting inserts equipped on each of the pair of connecting belts extending from both sides of the bottom of the first storage compartment to the corresponding connecting receivers on the yoke on the back side via both sides of the body. At this time, the length of the pair of connecting belts can be adjusted according to the wearer's physique so that the first storage compartment is close to the body and the second storage compartment is carried on the back like a backpack. The first storage compartment, which is close to the body, is supported by the chest and abdomen, as well as by the yoke on the back side by the pair of connecting belts on its bottom side. Therefore, the swinging of the first storage compartment can be suppressed, and the load can be distributed by supporting the bottom of the first storage compartment from the second storage compartment side which is carried on the back, thereby reducing the weight (perceived weight) felt by the wearer of the bag.

[0010] The bag according to claim 2 is characterized in that, in the invention of claim 1, the first storage section has a tubular drawstring section at one end which is fixed along the opening edge of the first storage section and at the other end which has a string for tightening. According to the above configuration, the first storage compartment becomes a drawstring bag and can be easily opened and closed with a string. Therefore, it is possible to easily put in and take out items, and it is also possible to prevent items from falling out.

[0011] The bag according to claim 3 is characterized in that, in the invention of claim 1, the first storage compartment has a pair of first adjustment belts for adjusting the width of the gusset near the opening edge on both sides of the first storage compartment, and the second storage compartment has a pair of second adjustment belts for adjusting the width of the gusset near the opening edge on both sides of the second storage compartment. With the above configuration, the width of the gusset can be adjusted near the entrance edges of the first and second storage compartments to make it less likely for luggage to fall out.

[0012] The bag according to claim 4 is characterized in that, in the invention of claim 1, the first storage section has a first entrance adjustment section that adjusts the distance between the entrance edge of the first storage section facing the yoke section and the yoke section at the widthwise center, and the second storage section has a second entrance adjustment section that adjusts the distance between the entrance edge of the second storage section facing the yoke section and the yoke section at the widthwise center. With the above configuration, the size of the entrances to the first and second storage compartments can be adjusted at their respective widthwise central points. Therefore, the distance between the entrance edges of the first and second storage compartments and the connecting parts can be reduced, making it easier to prevent luggage from falling out. Furthermore, luggage stored in the first and second storage compartments can be held in place, bringing the luggage closer to the body and suppressing swaying. Consequently, the force (moment) that the person wearing the bag has to support the first and second storage compartments is reduced, and the swaying of luggage inside the first and second storage compartments is suppressed, further reducing the perceived weight.

[0013] The bag according to claim 5 is characterized in that, in the invention of claim 4, the first entrance adjustment portion has a first fastener consisting of two annular members fixed to the entrance edge of the first storage portion facing the yoke portion, and a first tape extending from the yoke portion side and insertable through the first fastener. According to the above configuration, by inserting the first tape through the corresponding first fastener and securing it, the entrance edge of the first storage section can be easily brought into close proximity at the center in the width direction.

[0014] The bag according to claim 6 is characterized in that, in the invention of claim 4, the second entrance adjustment portion has a second fastener consisting of two annular members fixed to the entrance edge of the second storage portion facing the yoke portion, and a second tape extending from the yoke portion side and insertable through the second fastener. According to the above configuration, by inserting the second tape through the corresponding second fastener and securing it, the entrance edge of the second storage section can be easily brought into close proximity at the center in the width direction.

[0015] The bag according to claim 7 is characterized in that, in the invention of claim 4, the first entrance adjustment part has a first receiving part equipped on the connecting part between the yoke part facing the first storage part and the first storage part, a first strap belt equipped on the entrance edge of the first storage part facing the yoke part, and a first insertion part equipped on the first strap belt for adjusting the length of the first strap belt and for inserting and fixing it to the first receiving part. With the above configuration, the length of the first strap belt can be adjusted by the first insertion part, and the first insertion part can be inserted into the corresponding first receiving part and fixed in place, thereby easily bringing the entrance edge of the first storage compartment close to the center in the width direction. Furthermore, the first insertion part and the first receiving part can be easily separated by releasing the fixation and easily re-fixed, so luggage can be easily put in and taken out of the first storage compartment.

[0016] The bag according to claim 8 is characterized in that, in the invention of claim 4, the second opening adjustment part has a second receiving part equipped on the connecting part between the yoke part facing the second storage part and the second storage part, a second strap belt equipped on the opening edge of the second storage part facing the yoke part, and a second insertion part equipped on the second strap belt for adjusting the length of the second strap belt and for inserting into the second receiving part and fixing it. With the above configuration, the length of the second strap belt can be adjusted using the second insertion part, and the second insertion part can be inserted into the corresponding second receiving part and secured, thereby easily bringing the entrance edge of the second storage compartment close to the center in the width direction. Furthermore, the second insertion part and the second receiving part can be easily separated by releasing the fixation and easily re-fixed, so luggage can be easily put in and taken out of the second storage compartment. [Effects of the Invention]

[0017] According to the present invention, the swinging of the two storage compartments is suppressed, and the load on these compartments is distributed, thereby reducing the weight felt by the wearer.

Modes for Carrying Out the Invention

[0019] Hereinafter, modes for carrying out the present invention will be described based on examples.

Example

[0020] As shown in FIGS. 1 and 2, the bag 1 has a rectangular outer shape and is flexible. A first storage part 20 for storing luggage is connected to one end of the length direction of the yoke part 10, and a second storage part 30 for storing luggage is connected to the other end. An opening 11 for inserting the head is provided at the central part of the yoke part 10. This bag 1 is called a newspaper bag configured to insert the head through the opening 11 so that the first storage part 20 is on the front side (chest side) of the body and the second storage part 30 is on the rear side (back side) of the body, and support the yoke part 10 with both shoulders. Incidentally, the direction orthogonal to the length direction of the yoke part 10 is defined as the width direction.

[0021] The yoke portion 10 and the first and second storage portions 20 and 30 are made of cloth (for example, canvas). A portion of the opening edge 21 of the first storage portion 20 is sewn to one end of the yoke portion 10 in the longitudinal direction so that the gusseted, bag-shaped first storage portion 20 bulges out from one side of the yoke portion 10. A portion of the opening edge 31 of the gusseted, bag-shaped second storage portion 30 is sewn to the other end of the yoke portion 10 in the longitudinal direction so that it bulges out on the same side as the first storage portion 20 and the openings of the first storage portion 20 and the second storage portion 30 face each other.

[0022] The portions of the yoke portion 10 near the connection points 12 and 13 between the yoke portion 10 and the first and second housing portions 20 and 30 are reinforced by a plurality of triangular gussets 16a to 16d that connect the entrance edges 21 and 31 to the widthwise ends 14 and 15 of the yoke portion 10, respectively. Reinforcing rivets are provided at the connection points of the gussets 16a to 16d. Through holes 17a and 17b are provided in the widthwise center of the yoke portion 10 between the opening 11 and the first housing portion 20, and in the widthwise center of the yoke portion 10 between the opening 11 and the second housing portion 30, and grommets are fitted into the through holes 17a and 17b, respectively.

[0023] Next, we will describe the first containment section 20. Side pockets 23a and 23b are provided on the outer circumferential surfaces of the two side sections 22a and 22b of the first storage section 20, and a front pocket 23c is provided on the outer circumferential surface of the front section 22c of the first storage section 20, which is on the opposite side of the connection section 12 with the yoke section 10. The side pockets 23a and 23b are provided so that contents can be put in and taken out from the entrance edge 21 side. The front pocket 23c has two entrances so that contents can be put in and taken out from the left and right sides, and each of these entrances can be opened and closed with a zipper. In addition, a fluorescent tape 24 is fixed along the bottom edge of the front pocket 23c.

[0024] The side sections 22a and 22b that constitute the gusset of the first storage section 20 are provided with a pair of first adjustment belts 25a and 25b, whose length can be adjusted to adjust the width of the gusset, arranged along the entrance edge 21. The pair of first adjustment belts 25a and 25b are each equipped with insertion parts 26a and 26b for side release buckles. The receiving parts 26c and 26d for side release buckles corresponding to the insertion parts 26a and 26b are fixed to the connection between the side sections 22a and 22b and the front section 22c. The base ends of the first adjustment belts 25a and 25b are fixed to the connection between the side sections 22a and 22b and the rear section 22d.

[0025] The length of the first adjustment belts 25a and 25b is adjusted by adjusting the mounting position of the insertion parts 26a and 26b on the first adjustment belts 25a and 25b. The width of the gusset of the first storage section 20 is adjusted by fixing the insertion parts 26a and 26b of the first adjustment belts 25a and 25b to the corresponding receiving parts 26c and 26d, or by adjusting the length of the first adjustment belts 25a and 25b while the insertion parts 26a and 26b are fixed to the corresponding receiving parts 26c and 26d.

[0026] At the bottom 22e side of the first storage section 20, the base ends of a pair of connecting belts 3a and 3b are fixed to the connecting portion between the side sections 22a and 22b and the rear section 22d. The connecting belts 3a and 3b are each equipped with connecting insertion parts 4a and 4b, which are insertion parts for side release buckles.

[0027] Next, the second containment section 30 will be described. Side pockets 33a and 33b are provided on the outer circumferential surfaces of the side portions 32a and 32b of the second storage section. These side pockets 33a and 33b are designed to be accessed from the entrance edge 31 side. In addition, a fluorescent tape 34 is fixed parallel to the entrance edge 31 on the outer circumferential surface of the rear portion 32c of the second storage section 30, which is on the opposite side of the connection portion 13 with the yoke portion 10.

[0028] The side sections 32a and 32b that constitute the gusset of the second storage section 30 are provided with a pair of second adjustment belts 35a and 35b, whose length can be adjusted to adjust the width of the gusset, arranged along the entrance edge 31. The pair of second adjustment belts 35a and 35b are each equipped with insertion parts 36a and 36b for side release buckles. The receiving parts 36c and 36d for side release buckles corresponding to the insertion parts 36a and 36b are fixed to the connection between the side sections 32a and 32b and the rear section 32c. The base ends of the second adjustment belts 35a and 35b are fixed to the connection between the side sections 32a and 32b and the front section 32d.

[0029] The length of the second adjustment belts 35a and 35b is adjusted by adjusting the mounting position of the insertion parts 36a and 36b on the second adjustment belts 35a and 35b. The width of the gusset of the second storage section 30 is adjusted by fixing the insertion parts 36a and 36b of the second adjustment belts 35a and 35b to the corresponding receiving parts 36c and 36d, or by adjusting the length of the second adjustment belts 35a and 35b while the insertion parts 36a and 36b are fixed to the corresponding receiving parts 36c and 36d.

[0030] The base end of a foldable fabric flap 37 is sewn to the connecting portion 13 between the second storage section 30 and the yoke section 10. By unfolding this flap 37, the entrance to the second storage section 30 can be covered.

[0031] Next, we will explain the connecting belts 3a and 3b. Near the connecting portion 13, connecting receiving portions 4c and 4d, which are receiving portions for side-release buckles corresponding to the connecting insertion portions 4a and 4b of the connecting belts 3a and 3b, are fixed together with gussets 16c and 16d to the widthwise ends 14 and 15 of the yoke portion 10, respectively. By inserting and fixing the connecting insertion portions 4a and 4b of the connecting belts 3a and 3b into the corresponding connecting receiving portions 4c and 4d, the yoke portion 10 on the bottom 22e side of the first storage portion 20 and the yoke portion 10 on the second storage portion 30 side (back side) are connected.

[0032] The lengths of the connecting belts 3a and 3b are adjusted by adjusting the mounting position of the connecting insertion parts 4a and 4b on the connecting belts 3a and 3b. This length adjustment may be performed with the connecting insertion parts 4a and 4b of the connecting belts 3a and 3b separated from the connecting receiving parts 4c and 4d, or with the connecting insertion parts 4a and 4b fixed to the corresponding connecting receiving parts 4c and 4d. For example, with the bag 1 attached and the connecting insertion parts 4a and 4b fixed to the corresponding connecting receiving parts 4c and 4d, the length from the base end of the connecting belts 3a and 3b to the connecting insertion parts 4a and 4b can be shortened by pulling the ends of the connecting belts 3a and 3b, allowing the bag 1 to fit snugly against the body.

[0033] Next, the first and second inlet adjustment sections will be explained. As shown in Figure 3, at the rear surface 22d of the first housing section 20, the base end of the first tape 5a is sewn and fixed to the connecting portion 12 between the entrance edge 21 of the first housing section 20 and the yoke section 10, near the through hole 17a. This fixing of the base end of the first tape 5a is reinforced by a rivet. A rear pocket 23d, which can be inserted and removed from the entrance edge 21 side, is provided on the outer circumferential surface of the rear surface 22d of the first housing section 20. Although not shown in the figure, the base end of the second tape 5b is fixed in the same way as the first tape 5a near the through hole 17b of the connecting portion 13 between the entrance edge 31 of the second housing section 30 and the yoke section 10.

[0034] As shown in Figures 1 and 2, an annular member 29 consisting of two D-shaped or O-shaped rings is fixed to the center of the width direction of the front portion 22c of the first storage section 20 via a fixing member 28 that is sewn in a loop to the entrance edge 21. Similarly, an annular member 39 consisting of two D-shaped or O-shaped rings is fixed to the center of the width direction of the rear portion 32c of the second storage section 30 via a fixing member 38 that is sewn in a loop to the entrance edge 31. The first tape 5a extends so that its tip can reach forward of the front portion 22c of the first storage section 20 through the corresponding through hole 17a or opening 11. The second tape 5b extends so that its tip can reach backward of the rear portion 32c of the second storage section 30 via the corresponding through hole 17b or opening 11.

[0035] As a first entrance adjustment section, the size of the entrance to the first housing section 20 is adjusted at the center in the width direction by inserting and fastening the first tape 5a through the two annular members 29 (first fasteners), and the adjusted size can be maintained. Similarly, as a second entrance adjustment section, the size of the entrance to the second housing section 30 is adjusted at the center in the width direction by inserting and fastening the second tape 5b through the annular member 39 (second fastener) of the second housing section 30, and the adjusted size can be maintained.

[0036] When bag 1 is attached, the yoke section 10 bends to conform to both shoulders, causing both ends of the storage sections 20 and 30 in the width direction to be lower than the center. Then, by connecting the first storage section 20 and the yoke section 10 on the back side with connecting belts 3a and 3b, the first storage section 20 fits snugly against the body, and the second storage section 20 is carried on the back like a backpack. As a result, the load of the first and second storage sections 20 and 30 is distributed across both shoulders, chest and abdomen, and back, reducing the perceived weight. In addition, the first and second entrance adjustment sections bring the entrance edges 21 and 31 of the first and second storage sections 20 and 30 closer to the corresponding yoke section 10 (connecting sections 12 and 13) in the width direction center, making it easier to prevent items from falling out. At this time, the stored items are held in place by the first and second storage sections 20 and 30, bringing the center of gravity of the items closer to the wearer's body. Therefore, the force (moment) that the wearer of bag 1 exerts on the first and second storage compartments 20 and 30 is reduced, and the swaying of the first storage compartment 20 and the swaying of the luggage within the first and second storage compartments 20 and 30 are suppressed, thus reducing the perceived weight.

[0037] As shown in Figure 4, the entrance to the first storage compartment 20 is equipped with a drawstring section 27. The drawstring section 27 is made of a tubular piece of fabric, with one end sewn to the inner circumference of the entrance edge 21. The other end is formed to be tightened by one or two strings 27a that are passed through this other end and tied in a ring. The drawstring section 27 can be loosened to easily put in and take out luggage, and the drawstring section 27 can be tightened to prevent luggage from falling out.

[0038] The first and second entrance adjustment sections can also be constructed using strap belts and side-release buckles instead of the first and second tapes 5a and 5b and the first and second fasteners. Specifically, as shown in Figure 5, the base end of the first strap belt 6a, equipped with a first insertion part 7a as the insertion part for the side-release buckle, is fixed to the front part 22c of the entrance edge 21 of the first storage section 20 in the widthwise center. Then, the first receiving part 7c is fixed to the connecting part 12 between the first storage section 20 and the yoke section 10 in the widthwise center as the receiving part for the corresponding side-release buckle. Similarly, in the second storage section 30, the second strap belt 6b equipped with a second insertion part 7b and the second receiving part 7d are arranged on the entrance edge 31. The second storage section 30 may also be equipped with a flap 37.

[0039] By adjusting the mounting positions of the insertion parts 7a and 7b on the first and second strap belts 6a and 6b, respectively, the size of the openings of the first and second storage compartments 20 and 30 in the center in the width direction can be adjusted. The first and second opening adjustment section, composed of the first and second strap belts 6a and 6b, can reduce the perceived weight in the same way as described above. Furthermore, since the first insertion part 7a and the first receiving part 7c, and the second insertion part 7b and the second receiving part 7d can be easily fixed and separated, the size of the opening can be changed more easily than in the case of the first and second tapes 5a and 5b, making it easier to put in and take out luggage.

[0040] The first and second entrance adjustment sections may consist of a tape and a fastener on one side, and a strap belt and a side-release buckle on the other. The fixing positions of the tape and fastener may also be swapped, as may the fixing position of the strap belt and the fixing position of the receiving part of the side-release buckle. In these cases as well, the perceived weight can be reduced as described above.

[0041] The function and effects of bag 1 described above will be explained. Bag 1 is worn so that the head passes through the opening 11 of the yoke section 10, with the first storage section 20 positioned on the chest side and the second storage section 30 on the back side, and with the yoke section 10 supported by both shoulders. The connecting inserts 4a and 4b on a pair of connecting belts 3a and 3b extending from the first storage section 20 are fixed to corresponding connecting receivers 4c and 4d fixed to the yoke section 10 on the back side via both sides of the body, thereby connecting the first storage section 20 and the yoke section 10 on the back side. At this time, the length of the pair of connecting belts 3a and 3b can be adjusted according to the wearer's physique so that the first storage section 20 is close to the body and the second storage section 30 is carried on the back like a backpack. The first storage section 20, which is close to the body, is supported by the chest and abdomen, as well as by the yoke section 10 on the back side by the pair of connecting belts 3a and 3b on its bottom side. Therefore, the swinging of the first storage section 20 can be suppressed, and the load can be distributed by supporting the bottom side of the first storage section 20 from the second storage section 30 side which is carried on the back, thereby reducing the weight (perceived weight) felt by the wearer of the bag 1.

[0042] The first storage compartment 20 has a cylindrical drawstring portion 27 with one end fixed along the entrance edge 21 and the other end equipped with a drawstring 27a, so that the entrance of the first storage compartment 20 can be easily opened and closed. Therefore, luggage can be easily put in and taken out of the first storage compartment 20, and luggage can be prevented from falling out of the first storage compartment 20.

[0043] The first storage compartment 20 has a pair of adjustable first adjustment belts 25a and 25b near its entrance edge 21. The second storage compartment 30 also has a pair of adjustable second adjustment belts 35a and 35b near its entrance edge 31. This allows the width of the gussets at the entrances of the first and second storage compartments 20 and 30 to be adjusted, making it less likely for items to fall out.

[0044] The first and second entrance adjustment sections allow the size of the entrances to the first and second storage sections 20 and 30 to be adjusted at their widthwise centers. This reduces the distance between the respective entrance edges 21 and 31 of the first and second storage sections 20 and 30 and the connecting sections 12 and 13, making it easier to prevent luggage from falling out. Furthermore, as the stored luggage is held in place by the first and second storage sections 20 and 30, the center of gravity of the luggage is brought closer to the body. This reduces the force (moment) that the wearer of the bag 1 must exert to support the first and second storage sections 20 and 30, suppressing the swaying of the first storage section 20 and the swaying of the luggage within the first and second storage sections 20 and 30, thus further reducing the perceived weight.

[0045] When the first and second entrance adjustment sections are composed of first and second tapes 5a and 5b and first and second fasteners, the entrance edges 21 and 31 of the first and second storage sections 20 and 30 can be easily brought close together in the widthwise center by inserting and fastening the first and second tapes 5a and 5b through the corresponding first and second fasteners.
