BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a school bag in which the periphery of the upper opening of the school bag body, that is, the periphery of the school bag, is reinforced from the outside.

[0002]

2. Description of the Related Art Around the periphery of the upper surface opening of a school bag body forming a housing of a school bag, the so-called periphery of the school bag is greatly deformed due to the introduction and removal of teaching materials such as a textbook and a brush case, and wear and tear is severe. For this reason, the upper ends of the left and right large gores and the large partition plate have been reinforced by inserting a core material into the thickness thereof. In addition, the corner portion which is the overlap sewing portion of the large partition plate and the left and right large gore, and the overlap sewing portion of the back plate, the left and right large gore and the main lid plate,
In particular, these corners are often clamped by inverted U-shaped knobs because they are easily broken.

[0003]

However, the core material inserted into the wall of the large gore or the large partition cannot be positioned extremely close to the upper edge of the large gore or the large partition. Therefore, the shape retention and reinforcement of the edge of the upper end cannot be sufficiently performed, and the upper ends of the left and right large gores and the large partition plate must be individually reinforced.

In order to prevent the corners from breaking,
Further clamping the corners with an inverted U-shaped knob is cumbersome for the clamping operation, and the use of the above-mentioned knob is usually a matter of appearance due to the fact that ordinary school bags are made of leather or synthetic leather. It is strange and unnatural.
In addition, the local reinforcement by the knob has a disadvantage that the corner of the edge is torn or deformed from the edge of the edge. An object of the present invention is to eliminate these disadvantages.

[0005]

The configuration of the school bag according to the present invention which achieves the above object is as follows. The school bag main body 1 superimposes facing edges of the large partition plate 6 on the front side edges of a frame body in which the left and right large gores 4, 5 are erected continuously on the left and right sides of the bottom plate portion 3. The opposite edge of the back plate 2 is sewn to the rear side edge of the body by superimposition sewing, and the upper surface is open. The back plate 2 has a base end of the main cover plate 15 attached thereto.

[0006] bulging leather or synthetic leather or the like elongated series of reinforcing piece 17 made of, the central portion 17 ₁ in the upper outer surface of the large partition plate 6, covering the core material 19 along a upper outer side surface And sew the abutment on the left and right sides 1

[0008]

The periphery of the upper opening including the corners of the school bag body, that is, the periphery thereof, is easily reinforced from the outside.
That is, a series of reinforcing pieces and a core material are surrounded and sewn on the outer surface to reinforce the upper edges of the large partition plate and the left and right large gores, as in the related art, or to pinch them at the corners. Unlike the case where a metal fitting is clamped, the reinforcement can be easily and surely performed, and a required cushioning effect can be exerted by swelling the portion outward. Both ends of the reinforcing piece are covered and sewn on the upper edges of the left and right edges of the backing slab, the upper edges of the rear edges of the left and right large gores, and the left and right edges of the base end of the main lid plate. Can be.
