[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a backpack in which a bag body is carried by a pair of backpacks.

[0002]

[Prior art]

 Conventionally, in a backpack, the upper ends of a pair of backpacks are fixed to the center of the upper end of the backboard in an inverted V shape. However, it has recently been pointed out that it is difficult to carry the upper ends of a pair of backpacks without a space between them because of the improvement in physique. Attempts have been made to fix it in the center of the top of the board.

[0003] However, since the backpack is usually made thick with a cushioning material to receive the load on the shoulder, the upper end of this thick backpack is shaped and firmly connected to the backboard. There is a problem that it is difficult to perform.

In a kind of backpack, a special metal fitting (referred to as a back ring or the like) is attached to the center of the upper part of the backboard, and the upper end of the backpack is connected to this metal fitting so that it is strong and strong. The upper ends of the pair of backpacks can be fixed at a predetermined distance. However, the use of special hardware such as a land cell increases the cost and weight, and is not suitable for a lightweight backpack sewn with fabric or the like.

[0005]

[Problems to be solved by the invention]

 Accordingly, the present invention has been made in view of the above-described problems, and provides a backpack that can easily and firmly connect the upper ends of a pair of backpacks to a bag body with a simple configuration at a predetermined interval. That is the task.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an oblique portion 21, 21 formed at the center of the upper portion of the back body surface 12 side of the bag body 10 by cutting off both sides of one side in the longitudinal direction of the rectangular fabric into a triangular shape. The trapezoidal connection fabric 20 is attached by sewing the bottom side 22 facing the side where the oblique sides 21 and 21 are provided, and the upper end of the backpack belt 30 and 30 is attached to the connection fabric 20 by the above-described method.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the figure, reference numeral 10 denotes a bag body. The bag body 10 has a specific configuration in the illustrated example and in “Claim 2” and “Claim 2”. However, here, the configuration and shape are not particularly specified. It is sufficient to use a bag body of various known shapes and configurations.

The bag body 10 in the illustrated example forms a main body having an opening at the back plate surface 12, both side surfaces 16 a and 16 b, a bottom surface 18, and a front surface 17. The base end of the surface 11a is fixed, and the free end side of the lid surface 11a passes over the upper opening of the bag body to form an upper surface portion 11. Although not shown, the tip of the free end is locked. It is detachably locked to the front face 17 with a buckle or the like.

A substantially trapezoidal connecting cloth in which oblique sides 21 and 21 are formed by cutting off both sides of one side in the longitudinal direction of the rectangular cloth into a triangular shape at the upper center of the back body surface 12 side of the bag body 10. 20 is attached by sewing a bottom side 22 facing the side where the oblique sides 21 and 21 are provided.

The connection fabric 20 can be made of any suitable material as long as it is bendable. In the present embodiment, the same fabric material as that of the bag body 10 is used. Then, the bottom side 22 is sewn and attached to the upper center of the back body surface 12 side of the bag body 10. Here, the upper center on the side of the back plate surface 12 is not necessarily directly limited to the portion of the back plate surface 12 (of course, it may be sewn to the back plate surface 12). As shown in the figure, the upper surface 11 of the bag body 10 is sewn together to the sewn portion between the upper surface 11 and the back plate surface 12 (the sewn portion between the back plate surface 12 and the lid 11a in the illustrated example). It may be. In the illustrated example, the connecting fabric 20 is formed of two sheets, the bottom 22 is sewn to the bag body 10 with a sewing thread T1, and the peripheral edges of the connecting fabrics 20 are sewn to each other with a sewing thread T2.

The upper ends of the back straps 30 and 30 are fixed to the connecting cloth 20 so that the oblique side 21 and the upper end of the back strap 30 overlap in an orthogonal state. The back strap 30 is usually a thick main belt portion 30a for a shoulder which is thick and contains a cushioning material, and is connected to the lower end side of the main belt portion 30a by a buckle 31 so that the locking position can be adjusted. And an adjustment belt 30b. The upper end of the main belt portion 30a is sewn to the connecting cloth 20 (in the illustrated example, both sewn and studs are used), and the lower end of the length adjustment belt 30b is connected to the bag body. It is connected to both lower side portions of the back plate surface 12 by sewing or the like. Therefore, when the oblique side 21 and the upper end of the backpack 30 are positioned and fixed so as to overlap in an orthogonal state, the backpacks 30, 30 (especially, the main belt portions 30a, 30a) become substantially eight-shaped as shown in the figure. It will be mounted in a shape.

Next, the backpack according to claim 2 has a reinforcing seat plate 13 and a backing cloth 14 on the inner surface side of the upper surface 11 of the bag body 10 and a reinforcing band 15 on the outer surface side, respectively. At the outer portion of the plate 13, along the edge of the reinforcing band 15, the reinforcing band 15, the upper surface 11, and the backing material 14 are sewn.

The reinforcing seat plate 13 is generally used for a handbag, and is conventionally referred to as a band iron because it mainly uses an iron plate, but recently, a resin plate or the like is used. The reinforcing band 15 is formed by knitting or weaving chemical fiber yarn into a band shape. The reinforcing seat plate 13 and the reinforcing band 15 sandwich the upper surface 11 of the bag body 10 and are heavy in the bag. The upper surface 11 is not deformed even when the stored items are stored and held by a hand grip 50 described later. In other words, the present invention also serves as a handbag, and the structure of the handbag is effectively used for the upper end connecting portion of the backpacks 30, 30, as described later.

Between the upper surface 11 and the reinforcing band 15, a substantially trapezoidal connecting cloth 20 having two oblique sides 21, 21 formed by cutting off both sides of one side in the longitudinal direction of the rectangular cloth into a triangular shape. The connecting fabric 20 is sandwiched with the bottom side 22 facing the side where the hypotenuse portions 21 and 21 are provided, and the free end side of the connecting fabric 20 is arranged so as to protrude toward the back plate surface 12. 20 is sewn together with the reinforcing band 15 on the upper surface 11 (with a sewing thread T1). That is, the sewing position of the connecting cloth 20 to the bag main body 10 is performed together with the sewing of the upper surface 11 and the reinforcing band 15 to omit the sewing process. In this case, the load to be supported is made uniform by the reinforcing seat plate 13 so that the model does not collapse as in the case of using it as a handbag.

The reason why the upper ends of the backpack belts 30 and 30 are fixed to the connection cloth 20 so that the oblique sides 21 and the upper ends of the backpacks 30 overlap in an orthogonal state is as follows. The present invention is the same as claim 1, but the present invention further includes a handle 50 for carrying on the reinforcing band 15. Therefore, the present invention can be used in two ways: carrying bag and carrying bag.

In the present invention, as described above, the connecting cloth 20 is sewn to the upper surface 11 together with the reinforcing band 15, and the handle 50 is provided on the upper surface 11. It is necessary that almost the entire surface of the front surface 11 can be used, such as a system in which the lid surface 11a forms the upper surface 11 (referred to as a cover system) or a system in which the front surface 17 is opened and closed (the lower side of the front surface 17) as shown in the illustrated example. And the other side can be opened and closed with a zipper, so a three-side zipper system) can be used.

Next, in the invention of claim 3, the reinforcing seat plate 13 and the backing cloth 14 are stacked on the inner surface of the upper surface 11 of the bag body 10, and the reinforcing band 15 is stacked on the outer surface, respectively. At the outer side of the plate 13, the reinforcing band 15, the upper surface 11, and the backing material 14 are sewn along the edge of the reinforcing band 15, and a rectangular cloth is provided between the upper surface 11 and the reinforcing band 15. One side of the longitudinal direction is formed by laminating two substantially trapezoidal connection fabrics 20 having both sides cut off in a triangular shape to form oblique sides 21 and 21, and a bottom side opposed to the side where the oblique sides 21 and 21 are provided. 22, the free end side of the connecting cloth 20 is arranged so as to protrude toward the back plate surface 12, and the connecting cloths 20, 20 are sewn together with the reinforcing band 15 to the upper surface 11. 20 and the upper ends of the backpack belts 30 and 30 from the position of the oblique side 21. It is inserted between the binding fabrics 20, 20, and the oblique side 21 and the upper end of the backpack 30 are positioned so as to overlap in a perpendicular state, and the edges of both the connecting fabrics 20, 20 are sewn to each other. At this time, the upper ends of the backpack belts 30 and 30 are sewn and fixed together, and a handle 50 is provided on the reinforcing band 15 in addition to the configuration of claim 2. The dough 20 is made up of two sheets.

In other words, the two connecting fabrics 20 are overlapped to cover the upper end connecting portions of the back straps 30 and 30 from both sides, and it is a matter of course that the appearance is improved. When the edges of both connecting fabrics 20 are sewn together with a sewing thread T2, the sewing thread T2 becomes a reinforcing material.

[0027]

[Effect of the invention]

 As described above, according to the backpacks according to claims 1 to 3 of the present invention, the upper end connecting portions of the backpacks 30 and 30 have a predetermined distance interval via the connecting cloth 20. Since it can be connected to the bag main body 10, it is possible to provide a backpack that can be easily carried by a person with a good physique.

Further, since the present invention uses the connecting fabric 20, it is possible to provide a backpack that can connect the thick backpacks 30, 30 to the bag body 10 in a good manner as described above.

Although the invention according to claims 2 and 3 can of course be used also as a handbag, the reinforcing structure of the upper surface 11 of the handbag functions effectively even when used as a backpack. This makes it possible to provide a backpack that is difficult to lose shape.
