【Example】

 An embodiment of the school bag of the present invention will be described with reference to the drawings. Since the large turret 3 and 4 have the same structure, the large turf 3 will be described here, and the description of the large turf 4 will be omitted. Reference numeral 1 denotes a school bag body made of leather, synthetic leather, synthetic paper or the like. The back plate 2, the left and right large gussets 3, 4, the large partition plate 5 and the bottom plate 6 form a casing having an open upper surface.

The left and right large gussets 3 and 4 are integrally formed continuously on the left and right of the bottom plate 6, and the bottom plate 6 and the left and right large gussets 3 and 4 are formed on the respective front edges of the bottom edge of the large partition plate 5. And the left and right side edges are sewn respectively, and the bottom plate 6 and the left and right large gussets 3 and 4 are sewn to the rear side edge and the left and right side edge of the back plate 2, respectively. A school bag body 1 having a rectangular opening is formed.

As shown in FIGS. 2 and 3, the large ramie 3 is made of a natural leather or synthetic leather front plate 3a, a relatively soft synthetic paper back plate 3b, and a relatively hard synthetic paper. An intermediate plate 3c and a sponge core 7 arranged between the front plate 3a and the intermediate plate 3c are superposed on each other. The surface plate 3a portion in which the core material 7 is embedded serves as a band-shaped bulging portion 8.

The core material 7 is formed to have a length dimension from the opening edges of the large gussets 3 and 4 shown in FIG. 1 to the bottom plate 6, and has a width dimension smaller than the widths of the front plate 3a and the middle plate 3c. It is formed into a strip. As shown in FIG. 3, a larger cutout portion 7a having a shape similar to that of a light reflecting sheet 9 described later in detail is formed on the core material 7. The cutout portion 7a shown in the present embodiment is formed as a through hole that communicates the front and back surfaces of the core material 7, but the bottom wall is left on the contact end face side with the middle plate 3c of the core material 7. It may be formed as a recess.

The contact surfaces of the front plate 3a, the middle plate 3c and the core member 7 described above are adhered to each other with an adhesive. The front plate 3a and the middle plate 3c are sewn together with one thread 10 and 10 along both sides of the core member 7, and the front plate 3a, the middle plate 3c and the core member 7 are A single thread 10 is sewn in the longitudinal direction at the central portion of 7.

Further, the back plate 3b is adhered to the back surface of the middle plate 3c with an adhesive or the like, and the seams of the three threads 10 exposed on the back surface of the middle plate 3c are hidden by the back plate 3b. ing. The middle plate 3c is not always necessary, and the front plate 3a and the back plate 3b may be directly sewn together.

A light reflection sheet 9 is fixed to the surface of the front plate 3a facing the cutout portion 7a. As shown in detail in FIGS. 4 and 5, the light-reflecting sheet 9 has a substantially pentagonal outer shape, and is slightly thicker than the light-reflecting sheet 9 directly attached to the front plates 3a and 4a of the large broths 3 and 4. A substrate 9a made of a synthetic resin, a light-reflecting member 9b adhered to the surface of the substrate 9a via an adhesive or a double-sided tape, and a transparent synthetic resin polymerized on the surface of the light-reflecting member 9b. The protective film 9c is provided.

On the contact surface side of the protective film 9c with the light reflection member 9b, a pattern in which two children are crossing a pedestrian crossing is printed with black ink. In the present embodiment, this pattern is the reflection blocking portion B, and the portion of the light reflecting member 9a blocked by the reflection blocking portion B does not reflect the light emitted from the outside.

Around the protective film 9c, a reflection blocking portion C formed of a band of a predetermined width and colored with black ink is formed, and the reflection blocking portion C is thermocompression bonded to the substrate 9a and the light reflection sheet 9b. And the protective film 9c are integrated. Although the antireflection portions B and C are black in the present embodiment, this color may be changed as appropriate in accordance with the coloring of the large broths 3 and 4.

In this light reflecting sheet 9, a double-sided adhesive tape is adhered to the contact surface of the substrate 9a with the large gussets 3 and 4, and the front plate 3a and the middle plate facing the cutout portion 7a of the core member 7 are provided. A thread 10 is sewn along the antireflection portion C together with 3c.

By this stitching, the portion of the front plate 3a facing the cutout portion 7a is depressed into the through hole 7a of the core material 7 and the back surface of the front plate 3a abuts against the middle plate 3c, and the shape of the through hole 7a is followed. A concave portion 8a is formed. The depth of the recess 8a is approximately the height of the bulge 8 minus the thickness of the front plate 3a. On the other hand, the thickness of the light reflecting sheet 9 fixed in the concave portion 8a is set to be equal to or less than the depth dimension of the concave portion 8a so that the light reflecting sheet 9 is removed from the surface of the bulging portion 8. I try not to stick out. This prevents the hand, stationery, or the like from coming into contact with the edge of the light reflecting sheet 9 and curling or peeling.

Reference numeral 11 denotes a front pocket portion provided on the front side of the large partition plate 5, which is made of leather, synthetic leather, synthetic paper or the like, and is provided with small gussets 12 to 16, small partition plates 17 and 18, a front plate 19 and a bottom plate 20. As a result, the three front and rear storage parts that are open on the upper side are partitioned and shaped. In each of these storage parts, the rear one is gradually higher than the front one, and a fastener 21 is attached to the opening of the frontmost storage part and the other openings are opened.

Reference numeral 22 is a lid also made of leather, synthetic leather or the like, the base end edge of which is attached to the upper end edge of the back plate 2, and the tongue piece 22a is fixed to the free end portion. A tongue piece 22a is provided at its free end with a cap 22b which is engaged with a known lock (not shown) mounted on the bottom plate 6 of the school bag body 1. Reference numeral 23 denotes a pair of shoulder straps attached to the school bag body 1 (one of which is not shown). It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the gist thereof.

For example, in the above-described embodiment, an example in which the light reflecting sheet and the shape of the concave portion are similar to each other has been described, but the light reflecting sheet may have different shapes as long as the light reflecting sheet can be fixed in the concave portion. Even in this case, the same effect as that of the above-described embodiment can be obtained.

[0020]

[Effect of device]

 According to the school bag of the present invention, a core material is sandwiched between the front plate and the back plate forming the left and right large gussets to form a continuous strip-shaped bulge from the upper edge of the left and right large gussets to the bottom plate. That a cutout is formed in a part of the core material and a recess is formed in the bulging portion of the front plate, and the light reflection member and a transparent protective film are formed on the surface of the light reflection member. The light reflection sheet, which is overlapped and has a reflection blocking portion for blocking the reflection of light by the light reflecting member formed on a part of this protective film, is fixed to the front plate in the concave portion. The light emitted from the side of the school bag can be reflected, which can improve the visibility. Also, by attaching a light reflection sheet having a reflection blocking portion formed to a part of the large vine, it is possible to improve the decorative property.
