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; The left and right side walls and the bottom wall extend from the front edge of the bottom wall in a bellows-like manner, and are fixedly partitioned by the front wall of the main body. , notebooks and other 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 these, they are put in the front pocket, but this front pocket is narrow and is not really useful. There is no.

By the way, school bags are generally used by elementary school students from 1st to 6th grade.
It is used throughout the Rokuhei period 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 conceivable to widen the storage thickness of the main body (the distance between the front and rear walls), but if it is widened in advance, there is a disadvantage that in the lower grades, there are fewer textbooks and the like to be stored, so they may move around.

The present invention was developed in view of these drawbacks, and has a structure in which the main body does not have a front wall compared to the conventional school bag.
In other words, the inside of the main body (main storage part), which is a rigid tetrahedron with open top and front surfaces, is designed to have a wide structure that communicates with the empty space in the front pocket, and in the lower grades, these are separated from the main body. It is divided by a medium partition, and when the child reaches the upper grades, it can be removed and combined with the empty space in the front pocket to increase the volume.

Moreover, this partition can be easily attached to and removed from the main body, and can be manufactured at low cost.

The present invention will be described below with reference to the illustrated embodiments.

FIG. 1 shows a school bag B in which a partition A is loaded into the main body 1.

The main body 1 is a rigid tetrahedron with left and right side walls 2.3, a rear wall 4, and a bottom wall 5 (FIG. 3) but no front wall and whose top and front surfaces are open. is the vacant space of the front pocket 7 extending on the front side of the main body 1, that is, the rear chamber 1 of the front and rear chambers 9 and 10 partitioned by the partition plate 8 of the front pocket 7.
It communicates with 0.

That is, the front pocket 7 is made by sewing the rear edge of one relatively thick sheet made of leather or synthetic leather to the front edge of the left and right side walls 2, 3 and bottom wall 5 of the main body 1. The front plate 11 is sewn to the front edge of the front edge, and the partition plate 8 is sewn to the middle.Since the left and right side walls 12, 13 and the bottom wall are made of sheets, they have a bellows shape that can be expanded and contracted. It has become.

There is a zipper 2 on the front of the front plate 11 of this front pocket 7.
A small pocket 26 that can be opened and closed at 5 is attached.

The partition A is formed into a tetrahedron with an open top and rear surface by a front plate 14, left and right side plates 15, 16, and a bottom plate 17.

That is, as shown in FIG. 2, the partition A is formed by providing folding lines 27 to 29 on a piece of hard cardboard to integrally partition the front plate 14, left and right side plates 15, 16, and bottom plate 17. At the same time, folding lines 30, 31 are provided at both left and right ends of the bottom plate 17 to partition the left and right mounting pieces 32, 33, and the left and right side plates 1
5.16 and the bottom plate 17 are bent almost at right angles at the folding lines 27 to 29, and left and right mounting pieces 32 and 33 are riveted to the lower ends of the left and right side plates 15 and 16, respectively.

The left and right side plates 15 and 16 and the bottom plate 17 are on the left side of the main body 1. The inner surfaces of the right side walls 2, 3 and the bottom wall 5 are large enough to cover almost the entire area, and the left and right side walls 1
The interval 5.16 is slightly narrower than the interval between the left and right side walls 2° and 3 of the main body 1, and the partition A as a whole has a top and rear surface that can be inserted and removed completely into the main body 1. It is an open rigid tetrahedron.

In addition, this partition A has a front plate 14, left and right side plates 15, 16, and a bottom plate 17 and a left and right side plate 15.
．． Reinforcement bands 18 and 19 made of leather or synthetic leather are sewn to the reinforcing edges of the front plate 16, respectively, and an elongated reinforcing core plate 20 is interposed between the outer surface of the front plate 14 and the reinforcing band 18, and, Velvet fasteners (many small synthetic resin hooks embedded in a thin substrate) 21.22 are attached to the outer surfaces of the upper ends of the left and right panels 15 and 16, on the reinforcing band 18 and on the lower surface (outer surface) of the bottom plate 17. .23 is attached.

On the other hand, the main body 1 has a velvet fastener (a large number of synthetic resin loops provided on a thin substrate) 21' corresponding to the velvet fasteners 21 and 22 above on the upper inner surfaces of the left and right side walls 2 and 3. .
It can be removed and installed freely.

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 with the bottom contact plate 24. ', 22, 23', and in this state, the partition plate A is prevented from detaching from the main body 1 and moving therein, and the front plate 14
partitions the main storage part 6 and the rear chamber 10 of the front pocket 7, and the left and right side plates 15, 16 and the bottom plate 17 are along the left and right side walls 2, 3 and the bottom wall 5 of the main body 1, respectively, and keep them inside. Reinforce from

4 is a lock fixing metal plate fixed on the bottom wall 5 of the main body 1, and the bottom plate 24 is attached to this metal plate 35.
It is locked to this to cover it.

As is clear from the detailed description above, the school bag of the present invention has the following effects.

■ Unlike conventional school bags, the main body does not have a front wall; in other words, it has a wide structure in which the main storage area of the main body, which forms a rigid tetrahedron, and the empty space of the expandable front pocket are connected as one.
By removably loading the partition into the main storage part, it is possible to partition the main storage part from the empty space of the front pocket that communicates with it, and by removing it, the main storage part can be separated from the empty space. The storage capacity of the main body of the school bag can be adjusted to two levels, and the school bag can be widened and narrowed to suit lower grades with fewer textbooks and upper grades with more textbooks. It can be used in such a way that the parts do not move around and get damaged.

■ The partition body is made into a tetrahedron with the front and left panels, the right panel and the bottom panel open to the top and rear, and the gap between the left and right panels is slightly narrower than the gap between the left and right side walls of the main body. Therefore, it can be set in a stable state inside the main body, and the left and right side walls and bottom wall can be reinforced. Also, since it is an open type with no rear plate, the front and rear of the main body can be easily set. You don't have to worry about the width becoming narrow or getting in the way when putting in textbooks, etc.

■ Velvet fasteners are fixed to the upper inner surfaces of the left and right side walls of the main storage part and the upper outer surfaces of the left and right side plates of the inner partition, and the corresponding velvet fasteners are removably engaged to accommodate the main storage of the inner partition. Since the partition is regulated from being pulled out and removed from the section and from swinging, the partition can be easily attached to and detached from the main body.

(2) Since the partition is formed by folding a piece of hard cardboard, it is easy to manufacture and can be provided at low cost.
