Description

  The present invention relates to a school bag. More specifically, the present invention relates to a school bag characterized in that, in addition to a shoulder belt, an auxiliary belt for preventing the school bag from falling backward is detachable.

  As is well known, a shoulder bag such as a school bag represented by a school bag is supported by a child's body only by a shoulder belt. At this time, the length of the shoulder belt is optimal, and therefore almost the entire shoulder belt is almost entirely. If it fits the child's body, the weight load of the school bag is applied to the entire body of the child that is in contact with the shoulder belt via the shoulder belt, so that the school bag receives less weight. Become.

  However, the school bag including the shoulder belt is large relative to the size of the body, especially in the lower grades, which are just new to school, and when the shoulder belt is too short, Since it is not possible to smoothly move down the shoulder belt, it is common for the shoulder belt to be slightly longer, especially in the lower grades.

  Then, when the school bag is carried, it becomes difficult for the entire shoulder belt to fit the child's body evenly, and the school bag falls to the rear side of the child, and the school bag body A gap is formed between the upper part of the child and the back of the child, and the weight of the school bag is concentrated on the shoulder of the child.

  FIG. 8 shows this relationship. In the figure, if the shoulder belt is too long, when the school bag is carried on the back, the school bag falls to the rear side of the child, so that the back of the child and the school A gap is formed between the bag and the backrest portion. As a result, the weight of the school bag felt by the children increases.

  At this time, for first-year students who have just entered the school, the average weight is around 21 kg, while the school bag is around 1 kg and the textbooks are around 1 kg, and bears around 10% of the body weight. Therefore, even if the school bag fits the back of the child, the weight of the school bag becomes painful, but there is also a gap between the back of the child and the back of the school bag, If the weight of the school bag felt by the child increases, it may be difficult to go to school, and in some cases, you may not want to go to school.

Therefore, in the past, there has been proposed a method of attaching to a school bag with the shoulder belt facing upward. And if this method is adopted, the school bag is pulled diagonally upward toward the back of the child, so that it is prevented from falling back and creating a gap between the back of the child and the back portion of the school bag. can do.

  By the way, as mentioned above, the cause of the gap between the back of the school bag and the back of the school bag is caused by the shoulder belt being too long for the body size. Yes, this is peculiar to lower grades of elementary school, especially children who have just entered elementary school, and since elementary school is growing fast, elementary school is a time when the shoulder belt is too long for the size of the body. It is only a few months after admission.

  For that purpose, the method of attaching to the school bag with the shoulder belt facing upward as described above was adopted, thereby preventing a gap between the back of the child and the back portion of the school bag. In some cases, about a few months after entering elementary school, the shoulder belt becomes shorter, and the length must be adjusted again.

  In addition, when the method described above is employed, the shoulder belt is directed downward after being directed upward, and therefore, the degree of curvature of the shoulder belt is increased particularly in the vicinity of the connection portion with the school bag, The boundary portion of the portion facing in the upward direction is likely to be damaged, so that it is necessary to reinforce the portion by inserting a core material or the like, which may increase the cost. .

  Therefore, the present invention can effectively prevent the school bag from falling to the rear side of the child, particularly in the elementary school lower grades, and it is necessary to adjust the shoulder belt even when the child's body becomes large due to growth. The challenge is to provide no school bags.

The school bag of the present invention includes a body formed by a bottom plate and a pair of large gussets connected to both ends of the bottom surface, and a back plate attached to the back side of the body, Formed by a front plate attached to the front side of the body part, a body part with an opening at the top, a lid part attached to the body part so that the opening can be opened and closed, and attached to the back side of the body part In a school bag comprising a pair of shoulder belts,
A base end of the auxiliary belt is detachably attached to an upper side on the back side of the main body, and a tip end of the auxiliary belt can be locked to the shoulder belt.

  In the school bag of the present invention, the base end of the auxiliary belt is detachably attached to the upper part on the back side of the main body, and the front end of the auxiliary belt can be locked to the shoulder belt.

  Therefore, in the case where the school bag falls to the rear side of the child because the shoulder belt is too long, after pulling the auxiliary belt to the child's body side, the tip of the school bag is locked to the shoulder belt, It is possible to eliminate the fall to

  And at this time, in the school bag of the present invention, since it is a method of eliminating the backward fall of the school bag by using an auxiliary belt, it differs from the method of attaching the shoulder belt to the school bag with the shoulder belt facing upward. When the situation that the shoulder belt is too long for the size of the body is solved by the growth of the child, it is only necessary to remove the auxiliary belt, there is no need to readjust the length of the shoulder belt .

  In addition, since it is supposed to eliminate the back fall of the school bag by using an auxiliary belt, the shoulder belt will not bend more than necessary and will not hurt. There is no need to prepare.

  The school bag of the present invention includes a main body, and the main body is formed of a bottom plate and a pair of large gussets that are connected to both ends of the bottom plate in an upward direction.
