  Next, the auxiliary accommodating portion 16 will be described. In the figure, 16 is an auxiliary accommodating portion, and in this embodiment, the auxiliary accommodating portion 16 has a pair of gusset pieces and a front plate portion.

  The pair of gusset pieces constitute the left and right side walls of the auxiliary housing part 16, and the front plate part constitutes a front wall of the auxiliary housing part 16 by closing an opening between the pair of gusset pieces. At the same time, the bottom portion of the auxiliary accommodating portion 16 is configured.

  That is, in the drawing, 17 is a pair of gusset pieces. In this embodiment, each of the gusset pieces 17 has an elongated shape having a predetermined width, and one side portion along the longitudinal direction of the middle partition plate 10 is It is attached to each of the left and right end parts.

  The other side portions of the gusset pieces 17 are free ends. Accordingly, the pair of gusset pieces 17 are formed as opening portions 18 and the pair of gusset pieces 17 are opposed to the free end portions. It is possible to change freely from a state of falling toward the gusset piece 17 side to an upright state with the free end facing the front side.

  In addition, the width dimension of a pair of gusset pieces 17 is determined according to the accommodation amount of the auxiliary | assistant accommodating part 16 comprised with a pair of gusset pieces and a front board part. That is, when increasing the amount of accommodation, the width dimension of the pair of gusset pieces 17 may be increased. In addition, the length dimension of the pair of gusset pieces 17 is set to be equal to or smaller than the vertical dimension of the partition plate 10.

  Next, 19 is a front board part in the figure. That is, in the present embodiment, the front plate portion 19 is a sheet-like object having a quadrangular outline, and the left and right width dimensions are formed between the pair of gusset pieces 17 when the pair of gusset pieces 17 are erected. The lower opening 18 is attached to the lower part of the partition plate 10 (see FIG. 3), and the left and right ends are free ends. While constituting the wall of the front side of the auxiliary accommodating part 16, the bottom part of the auxiliary accommodating part 16 is comprised.

  Next, in the figure, reference numeral 20 denotes a communication means, which is composed of a stretchable elastic body. Specifically, in the present embodiment, the communication means 20 is constituted by a rubber string and communicates the pair of gusset pieces 17.

  Further, in the present embodiment, the communication means 20 is formed in a zigzag shape so that one end of each gusset piece 17 is knitted alternately, like a shoelace attached to a shoe. The pair of gusset pieces 17 communicate with each other.

  When the gusset pieces 17 are communicated with each other, in a normal state where no external force is applied, the pair of gusset pieces 17 are in a state where they fall down with their free ends facing the opposite gusset piece sides. Yes.

  Therefore, when nothing is contained in the auxiliary accommodating portion 16, the pair of gusset pieces 17 are in a state where the free end portions are inclined toward the opposite gusset piece 17 side, and thereby The face plate portion 19 is in contact with or close to the partition plate 10. On the other hand, when any load is put in the auxiliary accommodating portion 16, the front plate portion 19 moves in a direction away from the partition plate 10. At the same time, the pair of gusset pieces 17 gradually stand up toward the front side so that the pair of gusset pieces 17 are pushed by both end portions of the front plate portion 19. It is possible to widen the accommodation space and increase the accommodation amount of the auxiliary accommodation portion 16.

  3 to 5 are views showing the main accommodating portion 2, the front case accommodating portion 8 and the auxiliary accommodating portion 16, FIG. 3 shows a longitudinal side structure, and FIG. 4 and FIG. A plane is shown. 3 and 4 show nothing in the auxiliary accommodating portion 16, and thus the pair of gusset pieces 17 have fallen toward the opposite gusset piece sides, respectively. FIG. 5 shows that the front plate portion 19 moves in a direction away from the partition plate 10 and is pushed by both end portions of the front plate portion 19 by putting something in the auxiliary accommodating portion 16. A pair of gusset pieces 17 stand up, and the accommodation space of the auxiliary accommodation portion 16 is thereby expanded. In the figure, the communication means 20 and the locking fitting 21b are omitted for easy understanding.

  Next, the operation of the school bag of the present embodiment configured as described above will be described. As described above, in the present embodiment, the pair of gusset pieces 17 constituting the side wall of the auxiliary accommodating portion 16 are respectively provided. The free ends of the gussets are freely changeable from a state of falling toward the opposite gusset piece side, and the pair of gusset pieces 17 are communicated by the communication means 20 constituted by an elastic body that can be expanded and contracted. At this time, in a normal state in which no external force is applied, the pair of gusset pieces 17 are respectively in a state where the free end portions are tilted toward the opposite gusset piece side.

  Therefore, when nothing is put in the auxiliary accommodating portion 16 due to the elastic force of the communication means 20, the pair of gusset pieces 17 constituting the left and right side walls are tilted as shown in FIGS. In addition, since the thickness of the entire school bag does not increase, the auxiliary accommodating portion 16 does not get in the way.

  On the other hand, when a load is put in the auxiliary accommodating portion 16, as shown in FIG. 5, the pair of gusset pieces 17 changes to stand up against the elastic force of the communication means 20, thereby assisting in the auxiliary accommodating. Since the accommodation space of the part 16 can be widened, a relatively large luggage or the like that does not fit in the main accommodation part 2 or the front cylinder accommodation part 8 can be easily accommodated.

  At this time, in the auxiliary accommodating portion 16 of the present embodiment, the pair of gusset pieces 17 constituting the side walls of the auxiliary accommodating portion 16 stand up from the state where the respective free end portions are tilted toward the opposing gusset piece side. Therefore, in the state where the gusset piece 17 stands up, the auxiliary accommodating portion 16 can be made into a large box shape, and can accommodate a thick book or notebook as compared with the case where the front portion is simply constituted by an elastic body. Is also possible.

  In the above-described embodiment, the case where the front plate portion 19 has left and right end portions as free ends has been described, but the left and right end portions do not necessarily have to be free ends.

  For example, FIG. 6 is a figure for demonstrating the other structure of the relationship between the front board part 19 and a pair of gusset piece 17, and in FIG. 6 (a) (b), the right and left of the said front board part 19 is shown. While folding the end portion to the front side, the folded end portion is a portion indicated by 23 in the free end portions of the pair of gusset pieces 17 in a collapsed state, respectively, at the back side of the front plate portion 19 and the above-mentioned In the arrangement where the back surfaces of the gusset pieces 17 face each other, for example, they are connected by sewing. It is possible to change to the state of (b) where the gusset piece 17 stands up and expands the accommodation space, and since the left and right end portions of the front plate portion 19 are connected to the gusset piece 17, It is possible to prevent the front plate portion 19 from falling from the left and right sides.

  At this time, in the form shown in FIGS. 6A and 6B, the pair of gussets 17 in a state where the left and right end portions of the front plate portion 19 are folded to the front side and the folded end portions are folded down. Since the back surface of the front plate portion 19 and the back surface of the gusset piece 17 are connected to each other at the free ends, the gusset pieces 17 are erected to widen the gap between the opening portions 18 between the gusset pieces. Even if it is possible to respond.

  That is, in FIG. 6A, L is the width dimension of the opening between the pair of gusset pieces 17 when the pair of gusset pieces 17 are tilted, and when the gusset pieces 17 are erected in this state, As shown by L ′ in (b), the interval between the opening portions 18 increases. Therefore, for example, as shown in FIG. 6C, when the front side of the front plate part 19 and the back side of the pair of gusset pieces 17 are connected to face each other, the front plate part 19 becomes an obstacle and opens. Since the interval L ′ between the portions cannot be increased, the pair of gusset pieces 17 cannot be erected.

  However, the present invention in the form shown in FIGS. 6A and 6B can cope with the case where the gap between the opening portions is widened by raising the gusset pieces 17 without having such a problem.

  Therefore, in the auxiliary accommodating portion 16 of the form shown in FIG. 6 (a), like the above-described auxiliary accommodating portion, when nothing is put, the pair of gusset pieces fall over and do not get in the way, When a baggage is put in, the pair of gusset pieces changes to an upright state and the accommodation space can be expanded, and the left and right end portions of the front plate portion 19 are connected to the pair of gusset pieces 17. In addition, even if an accessory is accommodated, the accessory can be prevented from spilling out from the auxiliary accommodating portion 16.

  The school bag according to the present invention includes an auxiliary storage portion in addition to the main storage portion and the front case storage portion, and the storage space of the auxiliary storage portion can be changed, so that the auxiliary storage portion is obstructed when nothing is put in. Therefore, the present invention can be applied to all school bags having an auxiliary storage portion.
