2. Description of the Related Art A school bag is generally used by elementary school students from the first year to the sixth grade for six years, but the number of school supplies used increases from the lower grades to the upper grades. For this reason, the school bag body is pre-made with a capacity that can be used even in the upper grades. Therefore, when the school supplies stored in the school bag body are few, there is a space between the school supplies and the inner wall surface of the school bag body or between the school supplies.

[0003]

[Problems to be Solved by the Invention] When running while carrying a backpack with a space between the inner wall surface of the school bag main body and the school supplies or between the school supplies, the school supplies repeatedly collide with the inner wall of the school bag main body and the school supplies and the school supplies The inner walls of the body are easily worn or damaged.

Further, the impact of the school supplies colliding with the inner wall surface of the school bag body may be transmitted to the body through the school bag body and may adversely affect elementary school students who are in the process of developing.

The impact from the school supplies can be weakened by reducing the capacity of the main body of the school bag so that the space as described above cannot be created even if a small amount of school supplies is put therein. It becomes impossible to store many school supplies, which makes it inconvenient to use especially for older children who use more school supplies.

An object of the present invention is to provide a school bag that solves these various problems.

[0007]

The constitution of the present invention is as follows. The school bag body 1 is sewn to the front edge of the bottom slab 6 and the front edges of the left and right large gussets 3 and 4 which are integrally continuous to the left and right of the bottom slab, and the bottom edge and the left and right edges of the large partition slab 5, respectively. In addition, the rear slab 6 and the left and right large gussets 3 and 4 are sewn together with the rear edge and the bottom edge and the left and right edge of the back slab 2, respectively.

Further, a spring member 12 for fixing the school supplies Q such as textbooks and stationery is fixed to the inner surface of at least one of the back plate 2, the left large sash 3, the right large sill 4 and the large partition plate 5. .

[0009]

The operation of the present invention having the above construction is as follows. When the school supplies are stored in the school bag body in which the spring member is fixed to the large partition plate or the like, the gap between the school supplies or between the school supplies and the spring member can be reduced or eliminated.

That is, when there is a gap between the school supplies and the spring members or between the school supplies, the school supplies repeatedly collide with the spring members and the like when the backpack is carried on the back, and the impact due to the collisions reduces the gap. And weakened by elastic deformation of the spring member.
If there is no gap between the school supplies, the spring members, and the school supplies, even if the school supplies are run on their backs, the school supplies are elastically pressed by the spring members and do not move in the main body of the school bag, and no impact occurs.
