Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a school bag in which the periphery of the upper opening of the school bag body is reinforced.

[Conventional technology]

The main body of the school bag is formed by sewing the opposing edges of the bottom plate, left and right large rugs, large partition plate and back plate, but the so-called rim, which is the periphery of the top opening, , deformation due to putting in and taking out teaching materials such as pencil cases, and severe wear and tear. For this reason, the upper edges of each of the left and right large gores and the large partition plates are reinforced. In addition, the corner portions formed by overlapping and sewing the left and right ends of the upper edges of the large partition plate and the front ends of the upper edges of the left and right large rugs are particularly prone to fraying. For this reason, the corner portions are held and reinforced using knobs.

[Problem that the idea aims to solve]

In the conventional reinforcing method described above, the upper edges of the left and right gores and the large partition plate are individually reinforced at three locations, and the reinforcing work is troublesome. In addition, in order to prevent the corners from fraying, the corners are further clamped and reinforced with knobs.
In addition to the troublesome work of holding the bag, it also makes the school bag look unsightly, and furthermore, the local reinforcement with the knob may actually damage or deform the corner from the edge of the metal fitting. It was hot. The present invention has been proposed with the aim of eliminating these various drawbacks.

[Means to solve the problem]

The structure of the school bag of the present invention adopted to achieve the above object is as follows. The school bag body 1 is sewn together with the front edge of the bottom plate 6, the front edges of the left and right large rugs 3 and 4 that are continuous and integral on the left and right sides of the bottom plate 6, and the bottom edge and left and right edges of the large partition plate 5, respectively. It is formed by sewing the bottom edge and the left and right edges of the back plate 2 to the rear edges of the bottom plate 6 and the left and right large rugs 3 and 4, respectively. A series of reinforcing pieces 23 are attached to the upper ends of the large partition plate 5 and the left and right large gourds 3, 4, including the sewn corners between the left and right ends of the upper edge of the large partition plate 5 and the front ends of the upper edges of the left and right large gussets 3, 4. The edge is covered continuously over its entire length in an inverted U-shape and is fixed there. The upper portions of the left and right large gores 3, 4 that are close to the reinforcing piece 23 are externalized by a synthetic resin core 21 held between the front plate 20 and the back plate 19 that form the left and right large gores 3, 4. It bulges out towards the side, and the outer surface of its upper side is covered with a reinforcing piece 2.
It is almost flush with the outer surface of 3.

[Effect]

In the school bag of the present invention, the so-called rim, which is the periphery of the top opening including the corners of the school bag body, is reinforced with a series of reinforcing pieces. Unlike the case where the reinforcing work is carried out efficiently or by clamping a knob at the corner, the reinforcing work can be carried out efficiently and the appearance is good. The upper parts of the left and right large gourds themselves are reinforced by the core sandwiched between the front and back plates forming the left and right large gourds, so that they do not lose their shape, and the outer surfaces of the upper parts bulge outward due to the core. Since the reinforcing piece is substantially flush with the outer surface of the reinforcing piece, no external force is applied to the lower edge of the outer surface of the reinforcing piece, such as by directly hitting the lower edge of the outer surface of the reinforcing piece with a hand or an object that would cause it to turn over. Therefore, the reinforcement of the left and right gossains, which are usually particularly susceptible to damage, by the reinforcing pieces is further facilitated.

【Example】

The illustrated embodiment will be described below. 1 is a school bag body made of leather, synthetic leather, synthetic paper, etc., which consists of a back plate 2, left and right large gussets 3,
4. The large partition plate 5 and the bottom plate 6 form a housing with an open top surface. The left and right large gouges 3, 4 are integrally formed continuously on the left and right sides of the bottom plate 6, and these bottom plate 6 and the left and right large gores 3, 4 are attached to the bottom edge of the large partition plate 5 and the left and right sides of the large partition plate 5, respectively. In addition, the bottom edge and left and right edges of the back plate 2 are sewn to the respective rear edges of the bottom plate 6 and the left and right large rugs 3 and 4, thereby creating a rectangular shape on the top surface. The school bag main body 1 is configured to have an opening. In the above, the left and right large gouges 3 and 4 are formed by polymerizing and adhering a leather face plate 20 to a synthetic paper backing plate 19 and sandwiching a synthetic resin core 21 between their upper parts. Reinforcement piece 23 described below in 3 and 4
The top plate 20 on the upper side adjacent to is bulged outward. Further, a back decorative plate 22 made of leather is polymerized and adhered to the upper part of the back plate 19. And these front plates 2
0, the upper edge of each of the back plate 19 and the back decorative plate 22 is formed into an arc shape. Reference numeral 23 denotes a series of elongated reinforcing pieces made of leather or synthetic leather to the required width. Approximately one-fourth of the length on each side is attached to the upper edge of the left and right large gores 3 and 4, and approximately two-quarters of the length in the center. The length part is placed over the upper edge of the large partition plate 5 in an inverted U-shape, and the outer edge 23' is folded back to the inside back side and sewn together, and the left and right large gores 3, 4 and the large partition plate 5 are sewn together. It is sewn on. What is particularly important here is that the reinforcing pieces 23 are a series, and that the series of reinforcing pieces 23 are connected to the left and right ends of the upper edge of the large partition plate 5 and the front ends of the upper edges of the left and right large gores 3 and 4. The large partition plate 5 including the sewn corners and the upper edges of the left and right large gores 3 and 4 extend over their entire length, in other words, the large partition plate 5 and the left and right large gores that form the upper opening periphery of the school bag body 1. 3, 4 and the upper edges of the back plate 2, except for the upper edge of the back plate 2, the entire length is reinforced at once, and the above-mentioned corners are reinforced with conventional knobs or something equivalent. 23
Apart from this, there is no need to do anything that would pinch the person. Further, the outer surface of the reinforcing piece 23 is almost flush with the outer surface of the upper surface plate 20 of the left and right large gussets bulged as described above (FIG. 2), and the lower edge of the outer surface of the reinforcing piece 23 is It is also important to have a structure that prevents hands or objects from touching it and turning it up directly. Reference numeral 7 denotes a front pocket provided on the front side of the large partition plate 5, which includes small pockets 8 to 11, small partition plates 12, 13, front plate 14, bottom plate 15, etc., which are also made of leather, synthetic leather, synthetic paper, etc. As a result, three storage compartments, front and rear, with open upper sides are formed. The height of each of these storage sections is gradually increased from the front to the rear, and a fastener 16 is attached to the opening of the front storage section, and the openings of the other storage sections are left open. Reference numeral 17 is a main cover plate made of leather, synthetic leather, etc. as above, whose base edge is attached to the upper edge of the back plate 2, and a hanging plate made of magnetic material (not shown) is attached to the free edge. ing. Further, the bottom plate 6 is provided with a known locking body (not shown) containing a permanent magnet and having a locking rod, to which the locking plate is locked.
The main lid plate 17 covers the opening and front surface of the school bag body 1 and the pocket part 7. Reference numeral 18 denotes a pair of shoulder straps (one of which is not shown) attached to the school bag body 1. The upper edges of the small rugs 8 and 10 are inclined diagonally forward and downward, and elongated reinforcing pieces 24 and 25 made of leather or synthetic leather are placed over the upper edges in an inverted U shape, and the outer edges are It is sewn on the inside back side with the folded edges sewn together.

[Effect of the idea]

As is clear from the above description, the school bag of the present invention has the following effects. A series of reinforcing pieces continuously inverts the upper edges of the large partition plate and the left and right large gourds, including the sewn corners between the left and right ends of the upper edge of the large partition plate and the front ends of the upper edges of the left and right large gourds, over the entire length thereof. Since it is covered in a U-shape and fixed there, in other words, the periphery of the upper opening of the school bag body, except for the upper edge of the spine, is integrally reinforced by a series of reinforcing pieces. In addition to the significantly improved durability of the periphery of the opening, the upper edges of the large partition plate and the left and right large rugs have been individually reinforced, or the corners are equipped with knobs. Unlike the case where the reinforcing work is held in place, the reinforcing work can be carried out more efficiently, and the appearance is also excellent. The upper parts of the left and right large gussets near the reinforcing pieces bulge out due to the core, and the outer surfaces of the upper ends are flush with the outer surfaces of the reinforcing pieces, so that objects may not come into direct contact with the lower edges of the outer surfaces of the reinforcing pieces. Do not apply any external force that would turn it over. In other words, the edges of the main body of the school bag are reinforced by a series of reinforcing pieces and a core inserted into the upper part, and at the same time, the upper part protects the lower end of the outer surface of the reinforcing pieces from peeling off. increasing strength. Therefore, the reinforcement of the left and right gossains, which are usually particularly susceptible to damage, by the reinforcing pieces is further facilitated.
