Description

  The present invention relates to an improvement of a partition plate that prevents textbooks, notebooks, and the like housed in a main accommodation room of a school bag from moving in the accommodation room.

Conventionally, school bags are used for a long period from the first grader to the sixth grader, so the size of the main storage room of the school bag is large enough to accommodate textbooks, notebooks and other teaching materials used by sixth graders. Is formed. Moreover, the textbooks, notebooks, and other teaching materials accommodated in the main containment room may have many days or less days depending on the timetable. Furthermore, lower grade school children from 1st to 3rd grades inevitably use less teaching materials because lesson time is short.
For this reason, if schoolchildren in the lower grades use school bags that are the same size as those in the upper grades, there are few textbooks, notebooks and other teaching materials (hereinafter referred to as containments) in the main containment room, as described above. Naturally there was a space part.

Furthermore, in the main storage room of the school bag, prints and notices that are handed over at school are printed in A4 size, and the printed matter is often housed in a clear file and handed over. Therefore, the main storage chamber of the school bag is formed wide so that the A4-size clear file can be stored without bending.

For this reason, there is a considerable gap in the main containment room of the school bag for lower grade school children. In addition, since the items contained in the main containment chamber are not fixed at all, when a schoolchild who goes to school with the school bag on the back runs, the item in the main containment chamber swings up, down, left and right, and the center of gravity of the school bag moves. It becomes easy to do. For this reason, there is a problem that the schoolchild's body is shaken by the movement of the contents and it is difficult to run or the contents are damaged.

Therefore, various ideas have been made to reduce the movement of the items stored in the main storage room. For example, a plurality of grooves and projections are provided at an arbitrary interval vertically inside the gussets on both sides of the main storage chamber, and the position is changed by inserting a partition plate into the groove according to the amount of storage to be stored in the main storage chamber. In order to prevent the movement by holding the contained material. (Patent Document 1)

Furthermore, the partition plate which provided the 1st folding part and the 2nd folding part in the front support plate and the back support plate which were provided in the both ends width direction of the holding plate which partitions off the main storage chamber is used, respectively. As this partition plate, there is known a partition plate that is used by bending a bent corner portion of the support plate according to the amount accommodated in the accommodation chamber (Patent Document 2).

However, in the former device, a locking portion having a plurality of locking grooves is attached inside the large gusset portion in the main accommodating chamber, and a flat partition plate is inserted into the arbitrary groove of the locking portion. Since it stops, the structure is complicated and the locking part cannot be removed. Further, the latter invention is difficult to use because it has a complicated structure in which the first and second bent corners provided at the front and rear support portions provided at both ends of the partition plate are provided, and the second invention is adapted to the contents. It is troublesome and costly and uneconomical because it is necessary to bend the corners 1 and 2 each time.

Therefore, the present invention provides a partition plate that is lightweight, has a simple structure, and can be removed, so that elementary school students who carry the school bag, especially schoolchildren in the lower grades, can easily attach and sort the school bag. The purpose is to reduce the weight.

In order to achieve the above object, the present invention folds on both sides of a partition 12 made of a synthetic resin plate that is lightweight, flexible, and strong, having a width and height that can be accommodated in the main storage chamber 3 of the school bag 1. A substrate 11 formed by integrally forming an adhesive portion 16 that can be bent through the eyes 13, and a synthetic resin having a gusset width and height in the main housing chamber 3 that is lightweight, flexible and strong. It consists of a gusset board 20 made of a board,
The adhesive part 16 of the said board | substrate 11 is each attached to the surface of the said gusset board 20, It is characterized by the above-mentioned. Further, the folds 13 provided at both ends of the partition part 12 constituting the substrate 11 are provided with a plurality of slit parts 15 at arbitrary intervals, respectively. Furthermore, the notch part 18 is each provided in the up-and-down both ends of the crease | fold 13 provided in the left-right both ends of the partition part 12 which comprises the said board | substrate 11. Still further, the present invention is characterized in that a plurality of slit portions 15 and cutout portions 18 are provided at both upper and lower ends in the folds 13 provided at the left and right ends of the partition portion 12 constituting the substrate 11. Further, the bonding portion 16 constituting the substrate 11 and the gusset plate 20 are bonded by an adhesive or heat welding. Further, the bonding portion 16 constituting the substrate 11 and the gusset plate 20 are bonded by spot heat welding h.

Therefore, by attaching the middle partition plate 10 that is lightweight and has a simple structure having flexibility and strength to the main storage chamber 3 of the school bag 1 so as to be detachable, it can be easily used even by lower grade school children. . Further, the center of gravity of the storage S in the main storage chamber 3 can be positioned in the direction of the back plate 2 by changing the insertion direction of the partition plate 10 depending on the amount of the storage S stored in the main storage chamber 3. Therefore, it is possible to prevent the school bag 1 from swinging and to reduce schoolchildren's fatigue.
