Japanese Patent Application Laid-Open No. 2021-171305 (P2021-171305A)

Since the above-mentioned conventional school bag type bag uses leather or artificial leather, it is very heavy for elementary school children who are the target of use, and has poor breathability.

As a countermeasure, school bags made of synthetic resin, which are lighter than conventional school bag type bags, are on sale and are currently used by some elementary school children. However, some school educators and parents ban the use of school bags made of synthetic resin because their appearance characteristics are far from those of conventional school bags, saying that they may develop into bullying. ..

The present invention is for solving the problem of a school bag for elementary school children using such a conventional school bag or a synthetic resin cloth. By devising the material, structure and shape that make up the bag, we have realized weight reduction and load reduction while maintaining the appearance characteristics of the school bag, and it is necessary for the physical characteristics and growth of the individual user and the use of a wheelchair on a daily basis. The purpose is to provide a school bag type bag for elementary school children that considers more users, including a shoulder belt exchange method that realizes customization according to the school attendance scene of various children.

The present invention is made of a synthetic resin fabric or material, and is provided with a three-dimensional main body accommodating portion that imitates the silhouette of a conventional school bag, and a fastener-type opening that opens wide from the ceiling to the lower part of the front surface is provided, and the conventional school bag is provided. By eliminating the cover lid that can be seen in the bag, the weight is reduced while maintaining the appearance characteristics of the school bag, and the synthetic resin mesh material is used for the parts that come into contact with the body when the user carries the bag, especially the inside and back of the shoulder belt. By using the plastic to improve breathability and making the angle between the back and bottom 90 degrees or less, it becomes easier for textbooks etc. to be close to the user's body, and as a result, the center of gravity of the entire bag is closer to the user. The problem is solved by reducing the load on the person.

As mentioned above, the school bag type bag of the present invention not only realizes weight reduction and load reduction as compared with the conventional school bag type bag, but also improves breathability and looks like a conventional school bag type bag. By having the characteristics, the anxiety that "it may develop into a bag" is eliminated, and as a result, more elementary school children can comfortably go to school.

It is a front view which shows the main body storage part of this invention. It is a bottom view which shows the main body storage part of this invention. It is a right side view which shows the main body storage part of this invention. It is a schematic perspective view seen from the front side which shows in the closed state of this invention. It is a schematic perspective view seen from the front side which shows with the lid open state of this invention. It is a schematic perspective view seen from the back side of this invention. It is a comparative figure of the cross section (A) when the user carries this school bag type bag, and the cross section (B) when the user carries a conventional school bag type bag.

Is also good.

The angle (14) between the bottom surface and the back surface of the main body accommodating portion (1) is 90 degrees or 90 degrees or less. In particular, when the above-mentioned angle (14) is composed of 90 degrees or less, when the user carries the bag on his / her back, it becomes easier for textbooks and the like to be close to the user side, and as a result, the center of gravity of the entire bag is closer to the user side. Realizes a reduction in the load on the user. It is desirable that the above-mentioned angle (14) is set at 80 degrees or more and less than 90 degrees.

The main body accommodating portion (1) is made of a synthetic resin cloth or material, and is made of a member having a flexible synthetic resin core material inside.
