Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a back plate which comes into contact with a user's back when carrying a school bag.

The shape of school bags in Japan has been standardized over a long history. However, there are many cases where the backboard is designed with individual designs such as special patterns or trademarks. Around this time, designs and trademarks such as this pattern have traditionally been sewn by overlapping decorative fabrics, by changing the thickness of cushion material to create irregularities, embossing on leather, and sewing parts. I am trying to improve the seam curve, and I am not able to realize detailed and clear expressions.

[0003] Recently, in order to write fine characters and the like, there has been proposed a leather with a foil stamped on its surface, but this foil stamping has a problem in durability although it depends on the usage conditions. It is not very suitable for school bags that are used for a long period of 6 years.

[0004]

[Problems to be solved by the device]

 Therefore, the present invention has been made in view of the above problems, and is a display unit that is fine and clear and has a large durability (the "display" and the "display unit" in the present application are not only a trademark or a descriptive display, but also a design. It is an object of the present invention to provide a back plate of a school bag with a symbol.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention overlays a cushion material 2 on a substrate 1, and further overlays a flexible surface material 3 on the cushion material 2, and the surface material 3 has characters and pictures. The technical means is embodied by embroidering the display portion 4 made of a figure or a combination thereof.

Therefore, since the back plate of the school bag of the present invention expresses a unique design or trademark by embroidery, the back plate of the present invention has the function of expressing fine details clearly and richly. In addition, although the embroidery thread has been made strong recently, the cushion material 2 is interposed on the back side of the embroidered display portion 4 in the present invention, so that the embroidery thread is not affected by external force. On the other hand, the cushion material 2 acts as a cushioning material and has an effect of preventing the embroidery thread from being worn or broken.

Further, in the invention of “Claim 2”, the cushion material 2 having a locally different thickness is stacked or cushioned on the substrate 1 by combining the thick cushion material 2a and the thin cushion material 2b. A locally omitted portion of the material 2 is provided, and a flexible surface material 3 is overlaid on the cushion material 2, and the cushion material 2 is omitted at a portion of the surface material 3 that fits the thin cushion material 2b. For the part that fits the part, the technical means is embodied by embroidering the display part 4 consisting of letters, pictures, figures, or a combination thereof.

Therefore, the back plate of the school bag of the present invention has the display portion 4 embroidered on the portion of the outer cloth 3 that fits the thin cushion material 2b or on the portion where the cushion material 2 is omitted. Is located in the recess, making it difficult to contact with other objects, and thus making it more difficult to damage.

Further, in the invention of “claim 3”, the cushion material 2 is overlaid on the substrate 1, the flexible surface material 3 is overlaid on the cushion material 2, and the surface of the surface material 3 is arranged. The technical means is provided by embroidering the display portion 4 made of characters, pictures, figures or a combination of these so that the embroidery thread penetrates the lower surface of the substrate 1.

Therefore, since the back plate of the school bag of the present invention is embroidered so that the embroidery thread penetrates from the surface of the cloth 3 to the lower surface of the substrate 1, the cushion material 2 is sewn with pressure when embroidering. When the embroidery thread is strongly pulled so as to contract, the embroidered portion compresses the cushion material 2 and is recessed from the surroundings, and the embroidery thread of the display unit 4 has the effect of making it difficult to touch other objects.

[Embodiment of the invention]

 Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the figure, reference numeral 1 is a back plate substrate that forms a surface that contacts the back of the land cell. As the back plate 1, a plate-like material that is lightweight and has appropriate rigidity is used. The board 1 used to be made of cardboard, plywood, etc. in the old days, but recently, synthetic resin materials have been used. Recently, foamed resin plates have been used for further weight reduction, and synthetic resin corrugated cardboard-shaped products in which two thin plates are connected by securing a large number of voids are also used.

As in the prior art, the cushion material 2 is overlaid on the substrate 1 and the flexible surface material 3 is overlaid on the cushion material 2.

Although various materials having a cushioning property are used as the cushion material 2, in the present embodiment, a foamed synthetic resin body in the form of a sponge (either closed cells or continuous cells may be used) is used. ing. The cushion material 2 is used by cutting it into an appropriate thickness, but as for the thickness, as shown in "Fig. 4" and "Fig. 5", a plurality of layers are stacked to have a predetermined thickness. As for the shape, a plurality of pieces may be arranged to form a predetermined size and shape.

The flexible surface material 3 is usually made of relatively thin natural leather or synthetic leather, but the cushioning material 2 does not largely impair its cushioning property when the cushioning material 2 is covered. The material is not specified as long as it is bendable and soft. Since the thickness of the cushion material 2 may be locally changed as in the present embodiment, the surface material 3 to be laid on the cushion material 2 has some elasticity and may be wrinkled even if it is laid on an uneven surface. It is desirable to select the one that does not depend on it.

In the present invention, the display material 4 is embroidered on the surface material 3 with a display portion 4 made of characters, pictures, figures, or a combination thereof. That is, a design such as a trademark or a pattern is embroidered on the front fabric 3 as the display unit 4. The display unit 4 may be a trademark, school emblem, school name, or the like, or may be a simple pattern. As shown in FIG. 1 and FIG. 2, the display part 4 has a good appearance in the left and right center parts on the upper part of the back plate, and when the backpack is carried on the back, this upper part is almost on the back of the user. Since it is also a part that does not come into contact, it is suitable because it is less likely to be damaged, but its position is not particularly limited, and it may be applied to the entire surface of the front cloth 3.

However, it is necessary that the cushion material 2 is provided on the back surface side of the display portion 4, and the display portion 4 made of embroidery applied to a portion having a cushioning function by the cushion material 2 is an embroidery thread. Even if a part of the surface of the outer fabric 3 protrudes outward from the surface of the outer fabric 3, it is almost possible to avoid wear and yarn breakage.

The front cloth 3 may be embroidered by a conventional method, but the embroidery thread is made of a chemical fiber or a strong one containing the chemical fiber, and the embroidery thread is applied to the user's body. Of course, it is desirable to use a material that does not easily wear when pressed.

In the figure, 5 is a decorative fabric which is further stacked on the front fabric 3, and 6 is a decorative fabric which is further stacked on the decorative fabric 5 for reinforcing the shoulder strap mounting metal fittings and reinforcing. These are usually sewn to the substrate 1 together with the surface material 3 with sewing threads W1 and W2. The decorative cloth 5 is provided on the upper part of the back plate, and the surface cloth 3 on the lower surface side of the decorative cloth 5 may be omitted. Further, as mentioned above, since the upper part of the back plate hardly contacts the back of the user when carrying the backpack, the cushion material 2 therebelow is usually omitted.

Next, in the invention of “claim 2”, the cushion material 2 having a locally different thickness is superposed on the substrate 1 by a combination of the thick cushion material 2a and the thin cushion material 2b, or a cushion. A locally omitted part of the material 2 is provided.

Originally, the cushion material 2 was made to have a change in thickness so that the back plate fits the user's body when the school bag is carried on the back. An extremely thick edge cushion material 2c having a substantially U shape is interposed between the lower portions on both sides of the back plate and in the vicinity of the bottom portion to fit the roundness of the back.

However, the purpose of the present invention is to change the thickness of the cushion material 2 for another purpose. The thick cushion material 2a of the present invention is the edge cushion material 2c and the inner portion thereof. Etc. are included in the above.

Therefore, in the illustrated example, the thin cushion material 2b represents a portion thinner than the edge cushion material 2c, but the edge cushion material 2c is thicker than the thick cushion material 2a, It also includes a portion thinner than the cushion material 2c.

The local omission portion of the cushion material 2 is usually selected because the upper part of the back plate does not contact the back at all, and even if it is omitted, the back does not feel uncomfortable. However, in the case of a very limited local site, the cushion material 2 in the vicinity of it is pressed against the back and exerts a cushioning function as a whole, so that the site where the cushion material 2 is locally omitted is limited. Not something that is done.

Then, a flexible surface material 3 is superposed on the cushion material 2, and a part of the surface material 3 that fits the thin cushion material 2b or a portion that fits the cushion material 2 is omitted. The display part 4 is embroidered with characters, pictures, figures, or a combination thereof.

Therefore, the display unit 4 is arranged at a lower step portion than the surroundings. It is needless to say that when the front cloth 3 is overlapped, the front cloth 3 is made to follow the height difference on the back side, but it is necessary to fix this height difference. The outer cloth 3 is sewn to the substrate 1 with the sewing threads W3 and W4 along the lower edge of the height difference. That is, the sewing thread W3 shown in FIGS. 3 and 4 is for fixing the height difference between the edge cushion material 2c portion and the thick cushion material 2a portion, and the sewing thread W4 is the thick cushion material 2a portion. This is for fixing the height difference between the thin cushion material 2b and the cushion cushion 2b.

Next, in the invention of “claim 3”, the cushion material 2 is overlaid on the substrate 1, and the flexible surface material 3 is overlaid on the cushion material 2 in each of the above-mentioned cases. It is the same as the invention of the claim.

The embroidery thread penetrates from the surface of the surface material 3 to the lower surface of the substrate 1 to embroider the display portion 4 made of characters, pictures, figures or a combination thereof.

That is, in the inventions up to claim 2, only the front cloth 3 is embroidered to provide the display portion 4. However, in the present invention, the surface of the front cloth 3 is lower than the lower surface of the substrate 1 (the cushion material). It is designed so that the embroidery thread penetrates through 2). At the time of this embroidery, the embroidery thread compresses the cushion material 2, and the cushion material 2 is recessed at the embroidered portion. That is, since the substrate 1 has appropriate rigidity and does not deform when the embroidery thread is bound tightly, the bound embroidery thread deforms the surface material 3 and the cushion material 2 side. Therefore, the embroidery thread of the display unit 4 is located in a recessed portion as compared with the surroundings, and it is difficult for the embroidery thread to come into contact with other objects.

As shown in FIG. 5, this embroidery is provided on the upper part of the back plate. However, the back plate of a recent school bag has the shape of the user's back by adopting the edge cushion material 2c. As a result, the adhesive area with the back increases in the summer, especially when the edge cushion material 2c is provided in a U shape as shown in the figure, hot air accumulates inside the edge cushion material 2c, and It is pointed out that the back gets damp. Therefore, if the embroidered display portion 4 of the present invention is provided so as to reach one side such as the other side from one side of the back plate, the cushion material 2 can form a recessed valley portion, and this valley portion can form one side of the back plate. If it is continuous to one side such as the other side, it can form an air passage, and in addition to the display and decoration functions, it can be expected to have the effect of improving the feeling of use when the user's back does not get damp. is there.

[0031]

[Effect of the invention]

 As described above, the present invention constitutes the display part 4 by embroidery, so that it is possible to provide a backpack of a school bag to which a fine, clear, and colorful display part can be attached.

Further, in the invention of “Claim 1”, since the cushion material 2 is interposed on the back surface side of the display portion 4, the embroidery thread protruding to the outer surface of the outer cloth 3 is worn by the cushioning effect of the cushion material 2. It is possible to provide the back plate of the school bag having the display portion 4 which is prevented from being damaged or damaged and has a high durability.

Further, in the invention of “Claim 2”, characters, pictures, figures, or figures are attached to the part of the outer cloth 3 that fits the thin cushion material 2b or the part that does not include the cushion material 2. Since the display section 4 made of these combinations is embroidered, the back panel of the school bag having the display section 4 having a high durability can be provided because the display section 4 is located in a lower step portion than the surroundings. .

Further, in the invention of “Claim 3”, since the embroidery thread of the display portion 4 penetrates from the surface of the front cloth 3 to the lower surface of the base plate 1, the embroidery thread is a cushion. It is possible to provide the back plate of the school bag having the display portion 4 which is highly dented by tightening the material 2.
