Description

[Detailed explanation of the idea] This idea relates to the reinforcing structure of the main gusset of school bags.

Generally, the gusset of a school bag is made of a single piece of leather, which gradually deforms during daily use, and the upper end of the gusset is particularly prone to damage.

To prevent this, conventionally, as shown in Figure 1, the attachment of the metal plate 4 to the upper end of the girth 1 was reinforced with rivets, etc.; Children often insert umbrellas, whistles, etc. into the gaps, making the gaps even larger, reducing the reinforcing effect and even causing damage.

In addition, in order to prevent the sewn part between the large gusset 1 and the back plate 3 from peeling off, the upper end of the sewn part is reinforced with metal or leather claw pieces 5. ．． This required a lot of man-hours such as attaching the claw pieces 5.

In view of the above, this idea was created in order to avoid damage to the upper part of the large machi.
＜The purpose is to provide a school bag that can be easily manufactured.

This invention will be explained based on the drawings. FIG. 2 shows an embodiment of this invention, and 1 is a large machining.

The large gusset 1 is formed of a single piece of leather, and forms the side and bottom parts of the school bag, and the side ends of the large gusset 1 form the back plate 3 and the front skin 6.
is sutured to.

A reinforcement degree 2 made of leather is sewn to the upper part of the large gusset 1, covering the upper end of the large gusset 1, and a reinforcement degree side part 2a on the back plate side of the reinforcement degree 2 is extended to extend the back plate 3. The side edges of the are covered and sewn.

In this way, the reinforcing degree 2 uses leather as the material like the large gusset 1, so it has good followability to external forces and does not peel off easily. It has a triple-layer reinforced structure that is sufficiently reinforced and does not easily break.

Furthermore, by covering and sewing the side end of the back plate 3 with the reinforcement degree side part 2a which is an extension of one side of the reinforcement degree 2, the large gusset 1 and the back plate 3 can be simultaneously attached to the large gusset 1 and the reinforcement degree 2. The sutures between the gusset 1 and the back plate 3 or the gusset] and the reinforcement level 2 are prevented from peeling off.

As explained above, in this invention, the upper end of the large gusset of the school bag is covered and the reinforcement is sewn on, and the side parts of the reinforcement are sewn to the side edges of the back plate, so the large gusset is It is sufficiently reinforced and will not easily break or peel off even when used every day.Furthermore, the reinforcing member and claw pieces can be manufactured and attached at the same time, making it easy to manufacture and having excellent design. .
