DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a school bag, and more particularly, to a school bag provided with a reflector for traffic safety.

[0002]

2. Description of the Related Art Conventionally, there have been various proposals in which a reflective material is attached to a bag for traffic safety at night. The reflector is usually formed in a strip shape, cut into an appropriate shape, and sewn to an appropriate outer surface of the bag.

[0003]

However, sewing the above-mentioned tape-shaped reflecting material on the outer surface of the school bag is not good in appearance, and the school bag is frequently used (almost every day) and has a long service life. Since it is long (usually used for 6 years), it has a problem in durability when sewn to the outer surface, and has a problem that it has not been widely used.

In view of the above, there has conventionally been proposed a method in which a reflective material is housed in a metal fitting and the reflective metal fitting is attached to a school bag. However, this method has a problem that the use of the metal fitting is expensive and heavy. Since is a hard material, the mountable part is limited to a cover or gore part having a wide flat surface, and in a backpack, the back strap located only on the front of the user's body must maintain a bendable state,
Such a hard metal fitting cannot be attached, and there is also a problem in that it cannot reflect the light of the car coming from the front and draw the driver's attention.

In view of the above, the present invention has been made to solve the above-mentioned problem, and is mounted on a backpack at the front of the body during use, so that the reflective material can be formatted without impairing the bendability of the backpack. An object of the present invention is to provide a school bag that is well attached and has no problem in durability.

[0006]

In order to solve the above-mentioned problems, according to the above-mentioned object of the present invention, a cushioning material 23 is provided between a surface material 21 and a lining 22 in order to solve the above-mentioned problems. In a school bag using the backpacks 20, 20 which are encapsulated, a window hole 24 is provided in a portion of the dress material 21 which corresponds to the user's chest when the school bag is worn, and the dress material 21 of the window hole 24 and the cushion material are provided. 23, a reflective material 10 in which a cushion material 13 and a reflective tape 11 are wrapped in a transparent sheet 12 so that the cushion material 13 and the reflective tape 11 cover the window hole 24. Then, the edge portion 12c of the transparent sheet 12, which is extended a little larger than the cushion material 13 and the reflection tape 11 in the outer peripheral direction, is stored between the outer material 21 and the cushion material 23 and stored. Upon stitching 1 and the lining 22 in which took technical means characterized by being together sutured portion of the edge surface portion 12c.

[0007]

According to the present invention, the reflective tape 11 is used to carry the belt 2
It can be attached to a part located on the front side of the user's body 0, 20 and has an effect of reflecting the light of the vehicle coming from the front to call attention to the driver.

In the present invention, since the cushion material 13, the reflection tape 11, and the transparent sheet 12 can be all made of a flexible material, the present invention works so as not to impair the bendability of the backpacks 20,20.

Further, in the present invention, since the reflection tape 11 and the transparent sheet 12 are all located on the back side of the outer material 21 and the end faces thereof are not exposed, the appearance is improved.

[0010]

Next, an embodiment of the present invention will be described with reference to the accompanying drawings. In the figure, 1 is the main body of the school bag, and 20 is the backpack.

The back strap 20 may be a conventionally known one in which a cushioning material 23 is enclosed between a surface material 21 and a lining 22. In this embodiment, it is most apparent in FIG. As shown in the figure, a band material cut in a substantially S-shape with a gentle curvature is used for the outer material 21, so that the backpack band 20 can easily fit the body when worn by a user. In addition,
The outer material 21 is made of a thick cloth so that the strength is maintained as a whole, as in the conventional case.

Although it is the same as the prior art that the lining 22 is made of a thin and flexible fabric,
Although omitted in the drawing, a large number of small holes for venting air are formed in the entire surface of the backing 22 so that the cushion function of the cushion material 23 described later can be effectively drawn out.

The cushioning material 23 is provided by the lining 22.
It is the same as the conventional case that the cushion material 23 is wrapped with the outer material 21 and the lining 22 so that the cushion material 23 is wrapped with the outer material 21 and sewn together at the peripheral edges of both. In the embodiment, a relatively hard outer cushion material 23b obtained by cutting the cushion material 23 into substantially the same shape as the outer material 21 and a relatively soft inner cushion material 23a cut one size smaller are superposed. The shape retention is ensured by 23b, and a sufficient cushioning property is ensured by the inner cushion material 23a.

The outer cushion member 23b and the inner cushion member 23a are both made of a foamed synthetic resin material.

Although it is not clear from the drawing, the lining 22 is formed by adding up and down, the upper half lining 22 is different in color from the outer lining 21, and the lower half lining 22a is lower. Coloring the same color as 21 is the same as that generally performed conventionally from a decorative point of view. Note that the lining 22 and the cushioning material 23
Is also commonly attached in the prior art with a stud 26 inserted through both.

Further, the back strap 20 is folded at its upper end, and one side of the triangular ring 3a of the mounting bracket 3 fixed to the center of the upper portion of the back plate 1a of the school bag is rolled into the folded portion, and the folded portion is stuck or stuck. It is designed to be sewn and attached, and reference numeral 25 in FIG. 2 indicates a tack hole therefor. Also, buckle locking through holes 27, 27, 27,... Are juxtaposed in the free end side of the back strap 20 in the same direction as before.

According to the present invention, the window hole 24 is provided at the portion of the outer material 21 corresponding to the user's chest when the school bag is worn.
Is provided. Although the shape of the window hole 24 is not particularly limited, it is preferable that the window hole 24 has a vertically long shape. The reason is that the school bag is used by elementary school students in the growing period even if it is a part corresponding to the chest of the user. This is because the position changes considerably with the growth of the physique, and if the physique is set to be vertically long, even if the physique is different, it becomes possible to be visually observed from the front side of the body. For this purpose, it goes without saying that a plurality of window holes 23 may be provided in the vertical direction, instead of being vertically long.

Between the outer material 21 and the cushion material 23 at the window hole 24, the reflection material 10 which is formed by covering the cushion material 13 and the reflection tape 11 in a transparent sheet 12 is provided. The cushion material 13 and the reflection tape 11 enter the window hole 24, and the edge portion 12 c of the transparent sheet 12, which is slightly larger than the cushion material 13 and the reflection tape 11 and extends in the outer peripheral direction, is connected to the outer material 21 and the cushioning material. It is stored between the members 23.

As the reflection tape 11, a conventionally known reflection tape obtained by kneading a diffuse synthetic material such as a glass piece or a metal piece with a transparent synthetic resin material is used. The cushion material 13 is made of a foamed synthetic resin or the like. The cushion material 13 and the reflection tape 11 are wrapped with a transparent sheet 12 made of a synthetic resin sheet or the like. On the sheet 12b, the cushion material 13, the reflective tape 11, and the upper transparent sheet 12a (partly) protrude in a shape and thickness substantially matching the thickness of the window hole 24, and the protruding portion fits in the window hole 24. It has been made to enter.

That is, the cushioning material 13 formed in the shape of the window hole 24 and the reflection tape 11 are superimposed on the lower transparent sheet 12b formed one size larger than the window hole 24, and further formed larger than the window hole 24. Upper transparent sheet 1
The upper transparent sheet 12a and the lower transparent sheet 12b are heat-welded or high-frequency welded at the outer peripheral portions of the cushioning material 13 and the reflective tape 11.

In the window hole 24, the cushion material 23 on the back side of the outer material 21 swells, but when the outer cushion material 23b on the outer material 21 side is made of a relatively hard material as in the present embodiment, this swelling occurs. There are few outgoings. As a result, when the reflective tape 11 is interposed on the back side of the outer material 21, the window hole 24 becomes a concave portion, and the inner peripheral edge surface of the window hole 24 is exposed, resulting in poor appearance. The outer material 21 may be turned up. Therefore, in the present invention, the depression of the window hole 24 is formed in advance by using the transparent sheet 12, the cushioning material 13, and the reflection tape 1.
It is intended to be filled with 1.

When the outer material 21 and the lining 22 are sewn together, a part of the edge 12c is sewn together. This suturing may be performed so that the reflection tape 11 does not deviate from a predetermined position. Needless to say, it is not always necessary to sew the entire surface of the edge 12c.

[0023]

As described above, the present invention can provide a school bag in which the reflective tape 11 can be attached to the front part of the shoulder strap 20.

In the present invention, the reflection tape 11 is housed inside the outer material 21 so that the appearance is good.
Since the end face of 1 is not exposed, there is no fear of breakage from this portion, and a school bag with excellent durability can be provided.

Further, according to the present invention, the reflective tape 11, the transparent sheet 12, and the cushioning material 13 can be all made of a bendable material, so that the bendability of the shoulder strap 20 is not hindered. This has the effect of being easy.

Further, according to the present invention, almost all of the inside of the window hole 24 can be filled with the reflection tape 11, the transparent sheet 12, and the cushion material 13, so that the inner peripheral edge surface of the window hole 24 is not exposed, and the appearance is further improved. It is possible to provide a school bag that is improved and does not break up due to the edge of the window hole 24 being rolled up.
