[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a bag.

[0002]

[Prior art]

 Conventionally, a sports bag 70 as shown in FIG. 14 is known. Such a sports bag 70 is also used for school children and the like. The sports bag 70 is formed into a rectangular shape by connecting the outer sides of the rectangular front and back sides 72, 73 to each other with a gusset width forming member 74. A chuck opening / closing type mouth portion 76 is provided on the upper surface portion of the forming material 74 along the longitudinal direction thereof. Further, a pair of grip portions 77 facing each other with the mouth portion 76 sandwiched therebetween are provided on the upper portions of the side surfaces 72, 73, and the middle portions of the longitudinal faces on both sides of the gusset width forming member 74 are respectively provided. A connector 78 is attached.

Therefore, this sports bag 70 can be used as a hand-held type by the handle portion 77, and as shown in FIG. 16, the hanging strap body 80 is hung between the connecting members 78. It can also be used as a shoulder type. Further, as shown in FIG. 15, it is also known that two backpack strings 84 are connected in a ring shape to the backrest surface portion 83 of the bag 71 to form a rucksack type.

[0004]

[Problems to be solved by the device]

 In the case of sports bags for school children, etc., they are used every day, and the items stored in them range from lightweight items such as clothes for changing clothes to heavy items such as books. Is. Therefore, it is convenient to be able to change how to hold the bag depending on the contents of the bag.

Therefore, it is conceivable that the above-mentioned sports bag 70 is further provided with a backpack string so as to make it a rucksack type so that the bag can be held more easily than in the case of the shoulder type. However, as shown in FIG. 16, when the contents of the rucksack type bag 71 are heavy, the bag 71 loses its shape when it is carried on its back, not only looks bad, but also the center of gravity is biased backwards and it is easy to get tired. There is a drawback that This difficulty is particularly noticeable when a backpack string is provided on a bag whose body shape is not originally suitable for a rucksack type, such as a sports bag.

This is because sports bags and the like have low height and are not suitable for rucksack types, and therefore have low stability when carried on their backs. Further, at the portion where the upper end of the backpack string 84 is sewn to the upper part of the backrest surface portion 83, a strong pulling action such as turning in opposite directions as indicated by the arrows X and Y occurs, so comparison There was a drawback that the fabric of this sewn part was easily torn and the seam was damaged.

Further, when the sports bag 70 is used as a shoulder type (in such a case, the bag is generally heavy), since there is only one hanging string 80, if the usage time is prolonged, the hanging string is extended. There were times when the 80 bites into the shoulder, causing pain or stiff shoulders. Further, as shown in FIG. 17, the hanging cord 80 presses the upper corner portion 86 of the gusset width forming material 74, and the bag material or the cord material is worn out or the chuck of the mouth portion 76 is broken. There is also a drawback in that the upper corner portion 86 is crushed and deformed by the hanging cord body 80 to make the appearance worse.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to prevent the rucksack type bag from collapsing and to be easy to use. In addition, it aims to prevent damage when the bag is used as a backpack type. Furthermore, it can be used not only as a bag such as a sports bag but also as a rucksack so that it can be used widely according to various applications (that is, it is easy to use in any case and does not look bad). The purpose is to provide a bag that is durable and long lasting.

[0009]

[Means for Solving the Problems]

 In the present invention, in order to achieve the above object, the following technical measures are taken in a bag in which a back strap is provided on the bag body. That is, in the present invention, the back strap body is hung from one side surface of the bag main body, over the upper side of the bag main body, and over the lower portion of the other side surface.

Further, the present invention provides a bag in which one end of a backpack string is attached to an upper portion of a bag body and the other end of the backpack string is attached to a lower portion of the bag body. The one end of the cord body is also attached to a side surface that faces rearward while the bag body is carried on the back. With such a structure, it can be used as a rucksack type, but the back straps face backward from the user's shoulder over the bag body when the user carries the bag body on his back. It is designed to be hung on the side of. In other words, in this state, the back side of the bag body can be hung by the straps on the back so that the bag body does not lose its shape. Therefore, it does not look bad, and the center of gravity is not biased backwards and easily worn out.

[0011] Furthermore, in the backpack string, the end portion connected to the side surface that faces backward when the bag body is carried on the backpack is stretched in a submissive direction that does not oppose the tensile force acting on the backpack string. Is preferred. That is, when connecting one end of the back strap to the side that is facing backward when the back of the bag is carried by sewing, etc., this end should be oriented in the direction according to the pulling force generated when carrying the back (i.e., folded back). Since it is attached to the side of the bag body (without doing anything), the force in the flipping direction does not act at this part. Therefore, the material of the connecting portion is not torn or the seam is not damaged, and the damage can be prevented.

A portion of the backpack cord connected to a lower portion of the other side surface of the bag body is detachable from the bag body, and the backpack cord is stored on the one side surface of the bag body. It may be provided with string pockets to allow it. In this way, when the backpack string is not used, it can be stored in the string pocket without any hindrance. If one end of the backpack cord is attached to the cord pocket, it is convenient because the backpack cord can be completely stored in the cord pocket. In addition, if one of the shoulder straps is sewn inside the strap pocket so that the shoulder strap does not separate from the bag body, it is easy to take the strap strap in and out of the pocket. There is.

Further, in the present invention, a pair of grip portions are provided at upper portions of both side surfaces of the bag main body so as to sandwich the upper portion of the bag main body, and the back strap string is passed through the grip portions. Can be adapted to be. In this way, the two back straps are always aligned in the ring shape of the handle portion and do not open too much to the left and right. Therefore, it is easy to handle when the bag body is carried on the back or lowered. In addition, when the bag body is carried on the back, the handles will not be crushed by the straps, rubbing against each other and being damaged.

Further, in the present invention, there is provided a suspending cord body which can be passed over the bag body so as to straddle the upper side of the bag body, and the connecting tool for the suspending strap body connects the bag body with the suspending cord body. It may be provided on the bag body so as not to come into contact with the bag body when held. By doing so, when the bag body is used as a shoulder type, the connector may come into contact with the bag body and the fabric may be worn out, or the bag body may be crushed and deformed by the connection tool and may not look good. The disadvantage of doing this can be eliminated.

As a specific configuration for preventing the contact between the connecting tool and the bag body, the connecting tool may be provided near the upper end of the bag body. Further, as a specific structure of a bag having a backpack string, an opening portion that can be opened and closed is provided on the upper part of the bag body, a string pocket is provided on one side surface of the bag body, and an inner side surface of the string pocket is provided. , One end of each of the two carrying straps is sewn to the lining side of the bag body, and the other end of the carrying strap is detachably attached to the lower portion of the other side surface of the bag body. A connector may be provided.

Further, a pair of grip portions are provided on both sides of the chuck opening / closing type mouth portion, and a bag body provided with a string pocket on one side surface with respect to the mouth portion, and the bag body. It has two back straps with one end sewn in the strap pocket of the main body, and a separate hanging strap body. One is provided at each corner of the bag body, which is a diagonal position on the upper surface. Is provided, and two connecting tools are provided at a lower end of one side surface of the bag main body at a predetermined interval from each other. The bag body can be changed to a rucksack type, a crossing type, a shoulder type, or a handbag type by changing the connection mode of the body.

[0017]

[Embodiment of device]

 Embodiments of the present invention will be described below with reference to the drawings. The bag 1 according to the present invention may be a backpack type as shown in FIGS. 1 and 2, a cross type as shown in FIGS. 8 to 10 or a shoulder type as shown in FIGS. It can be used in various ways and, of course, can be used as a hand-held type.

As shown in FIG. 3, the bag 1 includes a bag body 2 having a rectangular shape, a hanging string body 3 prepared separately from the bag body 2, and As shown in FIGS. 6 and 7, it has two carrying straps 4 attached to the bag body 2 with one end thereof connected. In FIG. 3, the mouth portion 8 provided on the upper portion of the bag body 2 is of a chuck opening / closing type, and is provided so as to slightly wrap around not only the upper surface of the gusset width forming material 9 but also the longitudinal surfaces on both sides. . This allows the mouth to be wide open. One of the side faces 10 and 11 on both sides of the mouth 8 (side face 10) is provided with a large pocket 14 protruding outward with a predetermined thickness. On the side face 10, a zipper opening-and-closing type mouth portion 15 is arranged slightly above the large pocket 14 and is hung inwardly of the bag body 2 (see FIG. 4, FIG. 6, and FIG. 7). ) Is set.

Reference numeral 17 denotes a chuck opening / closing type mouth portion of the large pocket 14. Further, the large-sized pocket 14 is further provided with a thin pocket 19 having a zipper opening / closing opening 18 for separately storing thin small items (documents, wallets, tissues, etc.). A pair of grip portions 21 and 22 facing each other with the mouth portion 8 sandwiched therebetween are provided near the upper ends of both side surfaces 10 and 11, and one grip portion 21 and the other grip portion 22 are bundled together. A winding band 23 that allows winding is provided. A button hook 24 holds the winding state of the winding band. By winding the winding band 23, the grip portions 21 and 22 can be easily gripped, soft to the touch, and easy to handle.

One connection tool 27 is provided at each corner of the upper end of the bag body 2 (upper surface of the gusset width forming member 9) which is closer to both ends of the mouth portion 8 in the longitudinal direction and which is a diagonal position. 28 are provided. Further, as shown in FIG. 5, at the lower end of the side surface 11 where the large pocket 14 is not provided, two connecting tools 30 and 31 are provided at a predetermined interval from each other.

Since the bag body 2 is generally used with the large pocket 14 side facing outward and the opposite side facing inward (the surface facing the body), in the following description, the large pocket 14 side will be used. The side surface 10 is referred to as an “outward side surface 10”, and the opposite side surface 11 is referred to as an “inward side surface 11”. The bag body 2 and the string pairs 3 and 4 are particularly advantageous for weight reduction and tensile strength because they are formed by sewing using a nylon or poly chemical fiber cloth.

As shown in FIG. 4, the back strap 4 is provided with one end sewn into the above-mentioned strap pocket 16 and the other end through the length adjusting portion 34. A connecting tool 35 is attached. Therefore, the carrying strap 4 can be stored in the strap pocket 16 when not in use as shown in FIG. 6, and can be pulled out from the strap pocket 16 as needed as shown in FIG.

As shown in FIG. 6 and FIG. 7, the sewn portion of the strap 4 is not directly behind the outward side surface 10 but on the inner surface side (the surface on the inner side of the bag body 2) 10a of the string pocket 16. Then sewn on. As shown in FIG. 6, the back strap string 4 and the inner surface of the strap pocket 15 are sewn together by sandwiching the back strap string 4 between the inner surface of the strap pocket 15 and the band B. ing. Since the band B is sewn over the entire length of the inner side surface of the string pocket 16 in the width direction (not shown), the degree of connection with the inner side surface of the string pocket 16 by the sewing is high. The strength is increased by sewing the back strap body 4 so that it is covered with such a band portion B. Furthermore, the band B, the back strap 14, and the inner side surfaces of the strap pocket 15 are caulked by the rivet metal fitting A, and the degree of coupling is high.

Then, when the bag body 2 is carried on the back using the carrying strap body 4, the bag body 2 is attached in a direction according to the pulling force acting on the carrying strap body 4 (that is, without folding back). There is. Therefore, in this sewn portion, the flipping action in the opposite directions as shown by the arrows X and Y in FIG. 17 does not occur, and the cloth in this portion is not torn or the seam is not damaged.

As shown in FIG. 3, the hanging strap 3 has connecting fittings 37 attached to both ends thereof, and a length adjusting portion 38 provided at one end thereof. When not in use, the hanging string 3 may be stored in the large pocket 14 or the thin pocket 19 of the bag body 2, or in the bag body 2 itself. The usage status of the bag 1 thus constructed will be described.

First, in order to make a rucksack type as shown in FIGS. 1 and 2, as shown in FIGS. 4 and 7, pull out the backpack string 4 from the string pocket 16 and in the middle of the grip portions 21 and 22. After passing through, the connecting fitting 35 is connected to the connecting tools 30, 31 (see FIG. 5) below the inward side surface 11. When the bag body 2 is carried on the back in this manner, the back strap body 4 is stretched from the user's shoulder over the mouth portion 8 of the bag body 2 to the outward side surface 10 (facing backward). Therefore, unlike the conventional rucksack type (see FIG. 17), the bag body 2 does not lose its shape such that it hangs backward.

On the other hand, in order to make a crossing type as shown in FIG. 8 and FIG. 9, a connection tool 28 at one corner on the upper surface of the bag body 2 and a position in a diagonal direction with respect to this. The connecting fittings 30 on the inward side surface 11 to be attached are respectively connected to the connecting fittings 37 at both ends of the hanging string 3. In this way, when the bag main body 2 is put in the laid state as shown in FIG. 9A or 9B, the bag main body 2 fits the user's body and is stable even when both hands are separated from the bag main body 2. Like Therefore, since both hands can be freed, it is easy to move and it is possible to carry other luggage. It should be noted that such a method of using the bag main body 2 is extremely useful in that it can reliably protect against snooping and the like.

FIG. 10 shows a case where the dominant arm of the user is the opposite of the case shown in FIGS. 8 and 9. That is, the hanging string 3 is bridged between the connectors 27 and 31. In order to make the shoulder type as shown in FIGS. 11 and 12, the hanging cord 3 is hung on the bag main body 2 between the connecting members 27 and 28 on the upper surface thereof. Of course, when it is necessary to adjust the length of the hanging string 3, the length adjusting section 38 may be operated.

When the bag main body 2 is lowered from the shoulder in this way, the hanging cord 3 is attached to the bag main body 2 because the connectors 27 and 28 are positioned on the upper end side of the bag main body 2 as shown in FIG. There is no need to press the upper corner of 2. Therefore, unlike the conventional sports bag (see FIG. 16), the cloth is worn away at the upper corners of the bag body 2, and the upper corners are crushed and deformed by the hanging straps 3 to make the appearance unpleasant. There is no such thing.

By the way, the present invention is not limited to the above embodiment. For example, the mouth 8 of the bag body 2 may be of a zipper opening type, a belt tightening type, a squeezing cord type, a button fastening type, a velcro fastening type, or the like. Further, the outer shape and type of the bag body 2, the presence or absence of the large pocket 14, the gusset width forming material 9 and the like, the material quality, etc. are not limited at all.

The hanging string 3 may be separately provided with a dedicated one for use as a hanging type and a dedicated one for use as a shoulder type. The shoulder strap body 4 can be detachable from the bag body 2. In this case, the bag body 2 may not be provided with the dedicated string pocket 16. Therefore, the back strap 4 can be attached to the outward side surface 10 of the bag body 2 in an exposed state.

Further, the backpack cord body 4 is detachable from the outward side face 10, and the cord pocket is provided on the inward side face side 11 instead of the outward side face 10, and the backpack cord body 4 is placed in the cord pocket. May be stored. The back strap 4 and the hanging strap 3 can also be formed by a thin cord, a chain, a belt or the like.
