Description

  This device is mainly related to school bags used by elementary school students.

  The school bag has a storage unit that can store articles and a shoulder belt for carrying the storage unit. However, when the school bag is carried on the back of the school bag, the shoulder bag fits the user's body. The center of gravity does not move away from the body, and the school bag can be carried in a stable state.

  Therefore, in the conventional school bag, the lower connecting ring and the intermediate connecting ring of the shoulder belt are devised so that the shoulder belt fits the user's body when the user carries it.

  For example, in the school bag as shown in FIG. 7, the connection sides 22a of the lower connection ring 22 of each of the pair of shoulder belts 21 are inclined so as to become lower toward the outside (Patent Document 1).

  In the school bag thus configured, the back belt 21 has a lower outer edge of the back belt 21 closer to the user's body as shown in FIG. 8 than the normal back belt 21 as shown in FIG. Because of the inclination, when the school bag is carried on the back, the entire width of the carrying belt 21 is easily brought into surface contact with the portion of the user's flank to the chest, and the carrying belt 21 fits the user's body.

  Furthermore, in the school bag as shown in FIG. 10, as shown in FIG. 11, the part 23a which hits the inner half of each intermediate connecting ring 23 of the pair of shoulder belts 21 is twisted outward of the user's body. The shape is assumed (Patent Document 2).

In such a school bag, the shoulder belt 21 is inclined so that the lower outer edge approaches the user's body. Therefore, when the school bag is carried on the back, the shoulder belt 21 is placed on the portion of the user's flank to the chest. The entire width of the belt is easy to come into surface contact, and the shoulder belt 21 fits the user's body.

  However, in the conventional school bag, as described above, the outer edge of the lower portion of the shoulder belt 21 is inclined so as to approach the user's body, and when the user carries the shoulder, it is placed on the chest from the user's flank. Although the entire width of the shoulder belt 21 is in surface contact with the portion and the shoulder belt 21 is adapted to fit the user's body, the inclination angle of the shoulder belt 21 is constant and the user's physique is maintained. Accordingly, since it cannot be inclined at an arbitrary angle, it is not sufficient to fit the shoulder belt 21 in accordance with the body of the user of any physique. Moreover, since the school bag is mainly used by elementary school students who are growing up, it is not enough to keep the shoulder belt 21 fitted to the body of the elementary school student whose body size is getting bigger and bigger.

  Further, in the conventional school bag, as described above, the entire width of the shoulder belt 21 is easily brought into surface contact with the portion from the user's flank to the chest, so that the shoulder belt 21 fits the user's body. However, in the user's shoulder portion, the shoulder belt 21 is only in partial contact, and the entire width may not be in surface contact, and the shoulder belt 21 may not completely fit the user's body. .

  Therefore, the present invention solves the above-mentioned conventional problems, and the user can easily fit the shoulder belt to the user's body when the user of any physique is carried on the back. The purpose of this school was to provide a school bag that can keep the shoulder belt fitted to the body of an elementary school student that is getting bigger and bigger.

  The school bag of the present invention is composed of an upper belt 3a and a lower belt 3b. The lower belt 3b has a core made of a resin shape holding tape 8 at a portion that comes into contact with the user's body, and uses the lower belt 3b. The shoulder belt 3 that can be changed in shape so as to come into surface contact with a person's body is provided.

  And the school bag of this invention has a core material which consists of resin shape maintenance tapes 8 in the portion which contacts the user's body of upper belt 3a, and makes upper belt 3a surface contact with the user's body. Thus, it is assumed that the shoulder belt 3 that can be changed in shape is provided.

  Further, the school bag of the present invention is formed by sewing the exterior fabric 9 of the shoulder belt 3 and the resin shape holding tape 8 together.

  In the school bag of this invention, the exterior fabric 9 of the back belt 3 and the resin shape holding tape 8 are fixed with a ridge 11.

  Since this device is configured as described above, the user can easily fit the shoulder belt to the user's body regardless of the user's physique. It will be possible to always keep the shoulder belt fitted to the body of elementary school students who are getting bigger and bigger.
