Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backpack bag which has a good feeling of use when it is carried on its back.

[0002]

2. Description of the Related Art Conventionally known backpacks of this type, such as a school bag, have band mounting metal fittings attached to the upper center of the back of the main body of the bag, and mounting bands attached to both sides of the lower surface of the gusset. , The upper ends of the two bands are respectively locked to the mounting brackets, and the lower ends of the two bands are connected to the respective mounting bands, so that the ends of both bands are supported at three points located at the respective vertices of the triangle. Was attached to.

[0003]

However, if this kind of backpack is carried on the back, the backpack will be hung at one central part of the back, so that the movement of the shoulder scapula and the vibration of the body add to the lateral direction. It is easy to move and becomes unstable. In addition, when a large number of items are stored and become heavy, a load is applied to the back of the backpack bag, and the back of the bag body and the wearer's back are easily separated from each other, which is uncomfortable to use, and moreover it is easily painful. Then, this invention is made | formed in order to solve such a subject, and an object of this invention is to provide a carrying bag which is excellent in usability and easy to use.

[0004]

In order to achieve the above object, a backpack according to the present invention is provided with a front portion and a back portion, and a gusset portion surrounding both side edges and a lower edge between the front portion and the back portion and extending from the back portion. In the bag body, which is composed of a cover that covers the upper part and the front part of the gusset, a tubular part with both ends open having a required length is provided along the upper end of the back part, and one tubular part is provided in the tubular part. The back strap is inserted, and both ends of the back strap are attached to both lower ends of the back.

[0005]

[Operation] When carrying a backpack, the backpack band extends from both ends of the tubular part attached to the upper end of the back and abuts on both shoulders in parallel, so it is held firmly, and there is little rolling of the bag body and the back Fits well on the back, is less likely to hurt, and provides a good feeling of use.

[0006]

[Embodiment 1] An embodiment of a carrying bag according to the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a bag body, and the bag body 1 includes a storage part 5 having an upper portion opened by a front part 2 and a back part 3, and both sides of the front part 2 and the back part 3 and a gusset part 4 surrounding a lower side edge. Is forming. Further, the back portion 3 is extended as it is at the upper end edge of the back portion 3 to integrally provide a cover lid 6, and the cover lid 6 covers the opening of the accommodating portion 5 in an openable and closable manner. The covering lid 6 has a mounting piece 8 having hooks 7, 7 attached to both sides of its tip,
8 is provided so that the respective hooks 7, 7 are locked to the hook rings 9, 9 attached to the front portion 2.

However, 10 is a tubular portion having both ends open which is attached along the upper end of the back portion 3 by sewing means, and is formed to have a length slightly shorter than the lateral width of the back portion 3. In addition, a single shoulder strap 11 is inserted through the tubular portion 10. A shoulder strap 11 extending from both ends of the tubular portion 10.
The eggplant rings 12 and 12 are provided at both ends of each of the eggplant rings 1 and 2.
Retaining rings 13, 2 and 12 provided on both sides of the lower end of the back 3,
It can be detachably hooked on 13. The length of the backpack band 11 can be freely adjusted according to the user.

The backpack according to the present invention has the above-mentioned structure, and both ends of the band 11 and both ends of the tubular portion are located at respective vertices of a substantially square shape. That is, back 3 when carrying
Since the shoulder straps 11 extending from both ends of the tubular portion 10 attached to the upper end of the bag contact the shoulders in parallel with each other, the usage state is stable, the lateral movement of the bag body 1 is small, and the bag body 1 has both sides. Since each of them is supported by the shoulder straps 11, the load is distributed, and even if a large number of objects are stored and the bag body 1 becomes heavy, the fatigue is relatively small.

FIG. 3 shows a state in which the backpack band 11 is removed from the bag body 1. If the backpack band 11 can be independently removed in this way, and if it is damaged, the bag body 1 is not included and only the backpack band 11 is removed. It is economical because it can be exchanged.

Further, the backpack bag shown in FIG. 5 shows another embodiment, in which the upper end of the back portion 3 of the bag body 1 is bent outward in a tubular shape, and the tip portion thereof is integrated with the back portion 3. Sew on the tubular part 1
0a is formed. In this case, the covering lid 6 is formed separately from the back portion 3 in advance, and the tip edges are sewn together to be integrally assembled. In this way, by bending the back portion 3 to integrally form the tubular portion 10a, the sewing process becomes easier and the workability is improved. The backpack according to this embodiment is particularly suitable for a school bag used by children, but the backpack is not limited to this and can be widely used with other backpacks.

[0011]

As described above, the backpack according to the present invention is provided with the tubular portions at the back and the back straps are extended from both ends thereof. Therefore, when carrying the back, the back straps are extended from both ends of the tubular portion. The shoulder straps that have come out come into contact with both shoulders in parallel, making it difficult to separate from the back, and there is almost no rolling and the usage condition is stable, giving a good feeling of use. Moreover, since both ends of the band and both ends of the tubular portion are located at the vertices of the substantially square shape, the load is distributed, and even if many objects are stored in the bag body, there is little feeling of fatigue and use. It can, and has a beneficial effect, especially for children in lower grades.
