Description

[Detailed Description of the Invention] Normally, school bags are made by stitching together the front edges of the left and right rugs and the left and right edges of the partition plate, and the upper end of this stitched area has an inverted U-shape. A knob is fitted to reinforce that part. Further, in order to prevent the upper ends of the left and right gore from losing their shape, a reinforcing core material is inserted and clamped within the thickness of the upper ends.

However, when using the above-mentioned knobs, the gore and partition plates are made of leather or synthetic leather, which gives a sense of incongruity in terms of the material appearance, and because the reinforcement is localized, the surrounding areas of the knobs may lose their shape or crack. In addition, with the core material that is inserted and clamped into the thickness of the gore, it cannot be positioned extremely close to the upper edge of the gore, so it is necessary to adequately shape and reinforce the upper edge of the gore. The disadvantage is that it cannot be done.

The present invention aims to solve the above-mentioned drawbacks and achieve an unprecedented decorative effect by surrounding and fixing a series of elongated reinforcing pieces to the upper outer surfaces of the partition plate and the gore on the left and right sides of the partition plate. be.

This will be explained below with reference to the illustrated embodiment.

Leather 1 is the main body of the school bag made of synthetic leather, synthetic paper, etc., and it is attached to the lower edge and left and right edges of the front of the back plate 2.
The rear edges of the bottom plate part 3 and the left and right large swings 4.5 that stand continuously on the left and right sides are overlapped and sewn together, and large partition plates are attached to the front edges of the bottom plate part 3 and the left and right large swings 4 and 5. The lower edge and left and right edges of 6 are overlapped and sewn together to form a straight shape with an open upper surface.

7 is a multi-stage storage section made of leather, synthetic leather, synthetic paper, etc. on the front side of the large partition plate 6, and it is located behind the bottom plate section 8 and the left and right small lattice 9° IO that stand continuously on the left and right sides of the bottom section 8. The edges are overlapped and sewn to the lower edge and left and right edges of the large partition plate 6, and the lower edge and left and right edges of the small partition plate 11 are attached to the front edges of the bottom plate part 8 and the left and right small gores 9 and 10. The middle partition plate 12 is inserted and erected between the left and right small rugs 9 and 10, and the lower edge and left and right edges of the middle partition plate 12 are connected to the bottom plate portion 8 and the left and right small rugs 9. It is sewn to a center shaft with approximately the front and back width of 1O.

Reference numeral 13 designates a pocket whose lower side and left and right edges are sewn to the front surface of the small partition plate 11, and whose top opening can be opened and opened with a zipper 14.

Reference numeral 15 denotes a main lid plate made of leather, synthetic leather, synthetic paper, etc., and its base end is sewn to the upper edge of the back plate 2.

16 is a shoulder strap.

Reference numeral 17 denotes a series of elongated reinforcing pieces made of leather or synthetic leather, etc. The central part 17' is sewn in contact with the upper outer surface of the large partition plate 6, and the left and right side parts 17", 17"' are attached to the left and right daifuku. 4 and 5, and both ends 17"" (only one shown) are sewn to extend slightly to the back surface of the main lid plate 15 through the left and right edges of the base end, and these both ends are sewn. Part 1
7", the upper edges of the left and right edges of the back plate 2 and the left and right Daifuku 4.
5 and the left and right edges of the base end of the main lid plate 15.

When sewing the above-mentioned strong piece 17, as shown in FIG. At the bottom of the reinforcing piece 17 sewn in direct contact with the position, an appropriate core material 19 is inserted and held within the wall thickness of the left and right daifuku 4.5 to reinforce the upper part of the daifuku 4 and 5 over a relatively wide range. (Figure 4).

In addition, in the above example, the large partition plate 6 and the left and right Daifuku 4.5
A reinforcing piece 17 was fixed around the upper outer surface of the holder.

Although only the cases 1. The surrounding fixation of the reinforcing piece 17 is carried out by the left and right small rugs 9 and 10 and the small partition plate 11, or by the left and right small m.
9, 10 and the upper outer surface of the partition plate 12.

As is clear from the above description, the school bag of the present invention has a series of elongated reinforcing pieces surrounding and fixed to the upper outer surfaces of the partition plate and its left and right gores over their entire length. are reinforced all at once, and because the conventional knob fittings are not fitted to the overlapping parts of the partition plate and the left and right gore, there is no appearance of material discomfort, and unlike the case of knob fittings. Particularly, according to the present invention, the upper edge of the partition plate and the gore can be easily shaped and reinforced without causing the peripheral portion to lose its shape or tear. be.
