Description

[Detailed description of the invention] A conventional school bag consists of a main body, which is a box-shaped rigid body with only the upper surface open, consisting of front and rear walls, left and right walls, and a bottom wall, and its left and right side walls and bottom wall. The front pocket, which is an auxiliary storage part, has left and right side walls and a bottom wall extending in a bellows shape from the front edge of the main body, and is individually partitioned by the front wall of the main body. School supplies are stored separately in the main body and in the front pocket, and mainly in the main body, and if they do not fit inside the main body, they are put in the front pocket, but the front pocket is so narrow that it is not really useful.

By the way, school bags are generally used by elementary school students from 1st to 6th grade.
It is used throughout the six years up to the first grade, and since the number of textbooks and the number of sorts that can be stored increases from the lower grades to the higher grades, it is desirable to make the capacity in advance so that it can be used even in the upper grades.

Therefore, it is possible to widen the storage thickness of the main body of the above-mentioned conventional school bag (the distance between the front and rear walls), but if it is made wider in advance, fewer textbooks, etc. can be stored there in the lower grades. It has the disadvantage of being nomadic.

Therefore, the present invention has a structure in which the main body does not have a front wall compared to the conventional school bag, that is, a wide structure in which the empty space of the main body forming a rigid tetrahedron and the empty space of the expandable front pocket are integrally communicated. In the lower grades, the empty space in the main body and the empty space in the front pocket are separated by a partition that is separate from the main body, and in the upper grades, this is removed and the empty space in the front pocket is divided into the empty space in the main body. This eliminates the above-mentioned drawbacks by integrating the space into a vacant room so that it can be used in a larger space.

The present invention will be described below with reference to the first embodiment shown in FIGS. 1 to 4 and the fifth embodiment.
Five embodiments will be described: a second embodiment shown in the figure, a third embodiment shown in FIG. 6, a fourth embodiment shown in FIG. 7, and a fifth embodiment shown in FIG. 8.

On the other hand, on the main body 1 side, velvet fasteners 21' and 22' corresponding to the above-mentioned velvet fasteners 21 and 22 are fixed to the inner surfaces of the left and right side walls 2 and 3, respectively, on the outer surfaces of the upper ends of the left and right side walls 2 and 3. One end of the wide belt-shaped connecting piece 27 and 28 made of leather is riveted, and the left,
A velvet fastener 23' corresponding to the above-mentioned velvet fastener 23, 24 is provided on the inner surface of the lower end of the right side walls 2, 3.
24' are fastened to each other.

Therefore, in order to load the partition A into the main body 1, the left
The rear edges of the right side plate 15, 16 and the bottom plate 17 are brought into contact with the inner surface of the rear wall 4, and the bottom plate 17 is inserted until it overlaps the bottom wall 5, and the left and right strip-shaped connecting pieces 27 and 28 are inserted inside the main body 1. In this state, the velvet fasteners 21 and 22 are bent to engage the velvet fasteners 21' and 22', respectively, and the velvet fasteners 23 and 24 are engaged with the velvet fasteners 23' and 24'. The partition A is prevented from being removed from the main body 1 and is prevented from moving therein, and its front plate 14 is inserted into the empty space 6 of the main body 1.
and the rear chamber 10 of the front pocket 7, and the left and right side plates 15, 16 and the bottom plate 17 partition the left and right side walls 2,
3 and the bottom wall 5, respectively, to reinforce them from the inside.

Next, referring to the second embodiment shown in FIG.
In addition to the bottom plate 17, a rear plate 14' is provided so that the rear wall 4 of the main body 1 can also be reinforced. A
The velvet fasteners 21 and 22 are attached to the left and right side walls 2 of the main body 1 by bending the strip-like continuous feeding pieces 27 and 28 to the outside of the main body 1 and attaching them to the inner surfaces of the upper ends of the left and right side plates 15 and 16. ,3
The velvet fasteners 21' and 22' are engaged with the outer surface of the velvet fasteners 21' and 22'.

Velvet zipper 36', 3
7', it is possible to prevent the partition A from being removed from the main body 1.

In the above-mentioned Embodiment 1.2.3, the band-shaped connecting pieces 27 and 28 are attached to the main body 1 or the partition A as a separate body, but they may be formed integrally with the main body 1 or the partition A. It is.

As is clear from the above, the school bag of the present invention has a structure in which the main body does not have a front wall compared to the conventional school bag, that is, it has a structure in which the main body forms a rigid tetrahedron and a space in the expandable front pocket. With a wide structure that is connected as one,
By placing a partition inside the empty space of the main body, it is possible to separate that empty space from the empty space of the front pocket, and by removing this partition, the rain room can be widely used as one, and the main body can be accommodated. The amount can be adjusted in two stages, so the space can be widened or narrowed to suit lower grades with fewer textbooks to upper grades with more textbooks, and there is no problem in lower grades when there are fewer textbooks stored and they move around and get damaged. There is no such thing as that.

In addition, the inner partition is made into a tetrahedron with the front plate, left side plate, right side plate, and bottom plate open at the top and rear, so it can be set in a stable state inside the main body, and it also serves as reinforcement. Since it is an open type with no rear plate, there is no need to worry about the front and rear width of the main unit becoming narrow or getting in the way when inserting textbooks, etc., and the partition can be attached and removed from the main body. This can be easily done by connecting the upper end of the side wall of the main body and the upper end of the side plate of the partition body using a band-shaped connecting piece, and then releasing the connection.
