Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reduces the impact caused by a collision between a school bag used by elementary school students to attend school, particularly the school bag body and school supplies such as textbooks and stationery (hereinafter referred to as "school supplies") stored in the school bag. Regarding the school bag to let you.

[0002]

2. Description of the Related Art A school bag is generally used by elementary school students from the first year to the sixth grade for six years, but the number of school supplies used increases from the lower grades to the upper grades. For this reason, the school bag body is pre-made with a capacity that can be used even in the upper grades. Therefore, when the school supplies stored in the school bag body are few, there is a space between the school supplies and the inner wall surface of the school bag body or between the school supplies.

[0003]

[Problems to be Solved by the Invention] When running while carrying a backpack with a space between the inner wall surface of the school bag main body and the school supplies or between the school supplies, the school supplies repeatedly collide with the inner wall surface of the school bag main body, and the school supplies And the inner wall of the school bag body are easily worn or damaged.

Further, the impact of the school supplies colliding with the inner wall surface of the school bag body may be transmitted to the body through the school bag body and may adversely affect elementary school students who are in the process of developing.

On the other hand, the impact from the school supplies can be weakened by reducing the capacity of the school bag itself so as to reduce the space between the school supplies and their inner wall surfaces or the space between the school supplies. It has the drawback of being difficult to use afterwards.

It is an object of the present invention to provide a school bag that reduces the impact between the inner wall surface of the school bag body and the school supplies to prevent abrasion and damage to the school bags and school supplies and does not adversely affect the body of elementary school students who carry the school backpack. There is.

[0007]

The constitution of the present invention is as follows. The school bag body 1 sews the front edge of the bottom slab 6 and the front edges of the left and right large gussets 3 and 4 which are continuously integrated on the left and right sides of the bottom slab 6, and the bottom edge and the left and right edges of the large partition plate 5, respectively. It is formed by sewing the bottom slab 6 and the rear side edges of the left and right large gussets 3 and 4, and the bottom edge and the left and right side edges of the back slab 2, respectively. Further, a cushioning member 9 is fixed to the back surface side of at least one of the back plate 2, the left large crepe 3, the right large crepe 4 and the large partition plate 5.

[0008]

The operation of the present invention having the above construction is as follows. When the school supplies are stored in the school bag body and run with the school bag on the back, the school products repeatedly collide with the back plate or the like of the school bag body, but the shock absorbers fixed to the back plate or the like cause the collision. The impact is mitigated, and the damage to school supplies or school bags and the adverse effects on the body of elementary school children can be prevented.

Buffer members 14, 14 (one of which is not shown) similar to the buffer member 9 are adhered to the core material 12 portion on the back surface of the large broth 3, 4. Further, those cushioning members 1
Back plates 15, 15 (one of which is not shown) formed by covering synthetic resin fibers 4, 14 in a mesh shape with synthetic resin fibers or the like are adhered to the core members 12, 12 around the cushioning members 9, 9 or It is sewn on. And the front edge 13a of the front plate 13
Is folded back to the back side so as to sandwich the peripheral portion of the core material 12 and the back plate 15, and is sewn together with the core material 12 and the back plate 15 with the thread S2.

The left and right edges and the bottom edge of the large partition plate 5 are sewn to the front edges of the left and right large gussets 3 and 4 and the bottom plate 6, respectively. As shown in FIG. 4, the large partition plate 5 has a cushioning member 1 similar to the cushioning member 9 on the back side of a base material 5a such as synthetic paper.
6 is adhered, the buffer member 16 is further coated, and the back plate 17 formed in the same mesh shape as the above is polymerized,
The edge portions of the back plate 17 and the large partition plate 5 are sewn together.

Reinforcing pieces 18, 19, 20, 21 formed of leather or synthetic leather to have a required width are attached to the back plate 17 and the large partition plate 5 by covering them in a U-shape, and further bonded. It is sewn together with the back plate 17 and the large partition plate 5.

Reference numeral 22 shown in FIG. 1 is a series of elongated reinforcing pieces formed of leather or synthetic leather to have a required width. The upper and lower edges of the left and right large gussets 3 and 4 and the large partition plate 5 are covered with an inverted U shape, and the outer side. The end portions of the are folded back to the inner back surface to form end cover stitches, which are sewn to the left and right large gussets 3 and 4 and the large partition plate 5.

Reference numeral 23 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, which is a small gusset 24 to 27, small partition plates 28 and 29, and a front plate 30.
The bottom plate 31 and the like form three compartments, the front and the rear, which are open on the upper side. In each of these storage parts, the rear one is higher than the front one, and the fastener 32 is attached to the opening of the frontmost storage part and the openings of the other storage parts are open.

Reference numeral 33 is a main lid plate made of leather, synthetic leather, synthetic paper, or the like. The base end edge of the main lid plate is attached to the upper end edge of the back plate 2, and a hook plate (not shown) made of a magnetic material is provided at the free end. ) Is attached.

Further, a permanent magnet is built in the bottom plate 6,

(4) In the above embodiment, the back plate, the left and right large gussets, and the large partition plate are all provided with the cushioning members, but the following may be adopted. (A) A cushioning member is provided only on the back plate. (B) A buffer member is provided only on the large partition plate. (C) A cushioning member is provided on both the back plate and the large partition plate. (D) A cushioning member is provided on either or both of the left and right large gussets. (5) In the above embodiment, the case where the back plate is provided has been described, but it is not always necessary to provide it.

[0024]

According to the present invention, the following effects can be obtained. Since the cushioning member is fixed to at least one of the back plate, the left large crepe, the right large crepe, and the large partition plate, the shock between the school supplies and the school bag body can be absorbed and relieved. Therefore, it is possible to prevent abrasion damage to the school bag and school supplies, and further reduce the impact transmitted to the body of the elementary school student carrying the school bag.

By covering the cushioning member with the back plate, it is possible to prevent the school supplies to be put into and taken out from the school bag body from coming into contact with the peripheral edge portion of the cushioning member, whereby the school supplies can be smoothly put in and taken out and the cushioning member is Can be prevented from being peeled off.

(3) If the back plate is formed in a mesh shape, the air between the front plate and the back plate can freely flow in and out, so that the elastic deformation of the cushioning member can be performed quickly. it can.
