Description

  The present invention relates to a method of manufacturing various leather products such as clothing, bags, shoes, curtains, blinds, partitions, wall displays, rugs, laps, accessories, hats, table cloths, etc. by connecting a large number of leather pieces. is there.

Conventionally, as a method for designing a leather product, methods such as dyeing a leather fabric as a raw material, applying a pattern by embossing, and printing a surface of the leather fabric are known.
The methods of dyeing leather fabrics and patterning by embossing cannot be finely color-coded, so the design variations of leather products are limited.
In addition, although the method of applying print processing to the leather fabric increases the design variations, the texture of the leather itself is destroyed and the sense of quality of the leather product is lost.

  In the patent document 1 (Japanese Patent No. 4480791), the applicant of the present application is a cloth piece composed of a hexagonal central portion and first peripheral portions and second peripheral portions that are alternately positioned at the peripheral portion of the central portion. The first peripheral edge and the second peripheral edge share one side of the hexagon, and the first peripheral edge shares two vertices of the hexagon, and the boundary between the first peripheral edge and the central part. The line has a first notch that is shorter than the length of the side and longer than a quarter of the side, and the boundary line between the second peripheral edge and the central part is defined as “the length of the side. A second notch that is equal to or slightly longer than half the length of the “first incision length”, the three first incisions being the third of the other three different pieces of fabric of the same shape. 2 cuts and each cut can be fitted and connected, and the three second cuts are the front 3 The fabric pieces have been disclosed cloth, which is a fitted connectable to match the cut first cut and each of the three different cloth of another identical shape.

The cloth piece is very functionally functional and can constitute clothing, accessories, hats, etc., but leather is selected as the material of the cloth piece, and the first peripheral edge and the second peripheral edge are used for the product. When exposed on the surface, there is a problem that the leather fabric shrinks over time and the first peripheral edge and the second peripheral edge warp. In addition, since the lining of the cloth pieces appears in the appearance when the cloth pieces are connected, simply selecting leather as the material of the cloth pieces makes the back of the leather cloth appear in the appearance to produce a high-quality leather product. It was impossible to do.
Anyone can easily fabricate a cloth product, and the user can enjoy the enjoyment of handmade by the user and can be easily repaired by the user. However, when applied to high-grade leather products, there is a problem that the connection strength between the pieces of cloth is weak.

Japanese Patent No. 4480791

  When manufacturing various leather products such as clothing, bags, shoes, etc. by connecting a large number of leather pieces, the appearance and luxury of these products are maintained, and various design variations and delicate designs are realized. The purpose is to increase the connection strength between the pieces.

  The present invention is a method of manufacturing a leather product using a leather piece, the leather piece is bonded to the back of the leather fabric facing each other, the leather piece is a polygonal central portion and the center It consists of the 1st peripheral part and 2nd peripheral part which are located in the periphery of a part, and has an insertion port near the boundary line of a 1st peripheral part and the said center part, A 2nd peripheral part is other leather pieces. Inserted into the insertion port from the back side, exposed to the front side of the leather piece and connected a large number of leather pieces, a sheet-like nonwoven fabric pasted on the back side of the many connected leather pieces, To do.

In the method for manufacturing a leather product of the present invention, a three-dimensional design can be applied to the leather product by showing the peripheral edge of the leather product on the appearance of the leather product composed of a large number of leather products.
According to the method for manufacturing a leather product of the present invention, it is possible to manufacture a leather product having a high-class feeling because it is possible to prevent warping of the peripheral edge of the leather piece, and the back surfaces of leather fabrics of different materials and colors are made to face each other. By pasting together, various design variations and delicate designs can be realized.
Furthermore, since a sheet-like nonwoven fabric is pasted on the back of the connected leather pieces to reinforce the connection strength, there is no risk of product damage or the like.

It is the front view (FIG. 1 (1)) and side view (FIG. 1 (2)) of the leather piece used for this invention. The perspective view (FIG. 2 (1)) which shows the state which connected the seven leather pieces shown in FIG. 1, and the front view which shows the state in which the 1st peripheral part and the 2nd peripheral part curved in the connection state of the conventional leather piece ( FIG. 2 (2)). It is a front view (FIG. 3 (1)) which shows other embodiment of the leather piece used for this invention, and a figure which shows the state which connected this four leather pieces (FIG. 3 (2)). It is a front view (Drawing 4 (1)) which shows another embodiment of the leather piece used for the present invention, and a figure showing the state where these four pieces of leather were connected (Drawing 4 (2)). It is a front view (Drawing 5 (1)) which shows another embodiment of the leather piece used for the present invention, and a figure showing the state where these three leather pieces were connected (Drawing 5 (2)). It is a front view of the bag manufactured by the manufacturing method of the present invention.

  Hereinafter, a method for producing a leather product according to the present invention will be described with reference to the drawings.

FIG. 1 (1) is a front view of a leather piece 4 used in the present invention. The leather piece 4 has a regular hexagonal central portion 2 and first peripheral portions 10, 10 that are alternately positioned on the peripheral edge of the central portion 2. 10 and second peripheral edge portions 20, 20, and 20.
By alternately disposing the first peripheral edge portions 10, 10, 10 and the second peripheral edge portions 20, 20, 20, it is possible to connect the leather pieces 4 infinitely in a plane.
The first peripheral edge portion 10 and the second peripheral edge portion 20 are integrated with the central portion 2 while sharing one side of the regular hexagon of the central portion 2.

In the vicinity of the boundary line between the first peripheral edge portion 10 and the central portion 2, an insertion port 11 that is shorter than the length of the shared side and longer than ¼ of the side is provided.
Further, the boundary line between the second peripheral edge portion 20 and the central portion 2 is equal to or slightly less than ½ of “the length of the side−the length of the insertion port” from both ends of the shared side. Are provided with long cuts 22, 22. Here, “slightly long” is intended to exclude a length that cannot maintain the connection strength described below.

As will be described later, the insertion slot 11 and the notches 22 and 22 are fitted to each other and the leather pieces 4 are connected to each other. Therefore, in order to maintain the connection strength between the leather pieces 4, the length of the above range is necessary as the length of the insertion slot 11 and the notches 22 and 22. The preferable length of the insertion port 11 is ¼ to ¾ of the shared side, and particularly about ½ of the shared side is preferable.
Further, the widths of the insertion slot 11 and the notches 22 and 22 depend exclusively on the thickness of the leather piece 4. The notches 22 and 22 penetrate from the front surface to the back surface of the cloth piece.

  More specifically regarding the length of the insertion slot 11 and the lengths of the cuts 22 and 22, depending on the material, thickness, and use of the leather piece 4, a bag is produced with the leather piece 4 having a thickness of about 1 mm. In this case, in FIG. 1, if the length of one side of the regular hexagon is 15 mm, for example, the length of the insertion port 11 is 8 mm, and the lengths of the notches 22 and 22 are 4 mm.

  The size of the leather piece 4 depends on the nature and size of the product constituted by the leather piece 4, but there is no particular limitation. However, since the leather piece 4 used in the present invention is basically manufactured by connecting manually, for example, in the case of a regular hexagon, the length of one side is in the range of 10 to 900 mm. It is preferable to do.

  Although there is no special restriction | limiting in the shape of the 1st peripheral part 10 and the 2nd peripheral part 20, In addition to the manufacturing conditions of leather pieces, such as ease of manufacture, as 1st (2nd) peripheral part 10 and 20 Design is considered. In other words, the shape of the first (second) peripheral edge portions 10 and 20 determines the design of the surface of the leather product constituted by the leather pieces 4.

  In the present embodiment, the shape of the first (second) peripheral edge portions 10 and 20 is a triangle, but it may be a rectangle, a trapezoid, a semicircular shape, a semielliptical shape, or the like. In the case of the triangular shape, in addition to facilitating the connection of the leather pieces 4, the first peripheral edge 10 and the second peripheral edge 20 do not overlap with each other, so that it is easy to manufacture a thin leather product. .

  The length of the joint width that is the boundary line between the first peripheral edge 10 or the second peripheral edge 20 and the central portion 2 is equal to the length of the hexagonal side. If the joint width is shorter than the length of the hexagonal side, the connection strength may decrease. On the other hand, it is difficult to obtain a joint width longer than the length of the hexagonal side from one piece of leather fabric.

  The joint length of the first peripheral edge portion 10 and the second peripheral edge portion 20 (the length in the direction perpendicular to the length of the joint width) is not particularly limited, but can be easily removed when the leather piece 4 is pulled. It is necessary that the length is not so long. If the length of one side of the regular hexagon shown in FIG. 1 (1) is 15 mm, the joint length is about 9 mm. Moreover, it is also possible to make it 9 mm or more in consideration of the design of leather products.

FIG. 1 (2) is a side view of the leather piece 4, and the leather piece 4 is bonded with the back surfaces of the leather fabric 3a located on the front surface and the leather fabric 3b located on the back surface facing each other.
Although there is no restriction | limiting in particular in the said bonding method, It is preferable to roughen the back surface of leather fabric with a file etc., and to bond together using an adhesive agent etc.

  Since the leather pieces 4 are bonded together with the back surfaces of the leather fabrics 3a and 3b facing each other, the leather fabrics 3a and 3b are pulled together with each other to prevent the leather fabrics from shrinking over time. It is possible to prevent the peripheral edge of the warp. As a result, it is possible to prevent the first peripheral edge portion 10 and the second peripheral edge portion 20 from warping as shown in FIG.

There is no particular limitation on the thickness ratio between the leather fabric 3a and the leather fabric 3b, but the thickness ratio between the leather fabric 3a and the leather fabric 3b is preferably in the range of 7: 3 to 5: 5.
In the case of manufacturing a bag by the manufacturing method of the present invention, when the thickness of the leather piece 4 is 1.2 mm, the leather fabric 3a is preferably 0.8 mm and the leather fabric 3b is preferably 0.4 mm.

The thickness of the leather piece 4 is determined by the material of the leather fabrics 3a and 3b and the leather product to be applied. In general, it is considered that an easily connectable device is weak in strength, but on the contrary, it is easy to separate, so this point should be taken into consideration. Usually, the thickness of the leather piece is preferably 5 mm or less, more preferably about 0.1 to 3 mm.
When a bag is manufactured by the manufacturing method of the present invention, it is preferable that the thickness of the leather piece 4 is set to about 1 mm to 1.2 mm in consideration of the total weight and flexibility of the bag and ease of manufacturing.

Since the leather pieces 4 are bonded together with the back surfaces of the leather fabrics 3a and 3b facing each other, the leather product manufactured by the manufacturing method of the present invention has the first peripheral edge 10 and the second peripheral edge 20 at the time of use. Even if it is drowned, the lining of the leather fabrics 3a and 3b does not appear in the appearance.
Further, since the leather fabric 3b appears partially on the side surface of the leather piece 4 and the connecting portion between the leather pieces 4, various design variations and delicate changes can be made by changing the materials and colors of the leather fabric 3a and the leather fabric 3b. Design can be realized. FIG. 2 (1) is a perspective view showing a state in which seven pieces of leather pieces 4 are connected, and shows a state in which the leather fabric 3b partially appears on the appearance.

There are no particular restrictions on the types and colors of the leather fabrics 3a and 3b, but design properties such as color shading are considered in addition to the bonding strength and the texture of the entire leather piece 4.

About the leather piece 4 demonstrated above, the 2nd peripheral part 20 is inserted in the insertion port 10 of the other leather piece 4 from the back surface side, exposed to the surface side, and many leather pieces 4 are connected. In the present embodiment, the insertion port 10 and the cut 22 may be fitted.
Further, a sheet-like non-woven fabric is pasted on the back surface of these many connected leather pieces 4 to reinforce the connection. There is no particular limitation on the method for attaching the nonwoven fabric, and any method that can reinforce the connection between the leather pieces 4, such as attaching to the back surface of a large number of connected leather pieces 4 using an adhesive or the like, may be used.
FIG. 6 is a front view of a bag manufactured by the manufacturing method of the present invention.

Next, another embodiment of the present invention will be described with reference to FIG.
FIG. 3 (1) is a front view of the leather piece 4 used in the present invention. The leather piece 4 has a square central part 2, first peripheral parts 10 and 10 and a second peripheral part located at the peripheral part of the central part 2. FIG. Parts 20 and 20.

  In the present embodiment, the first peripheral edge portions 10 and 10 and the second peripheral edge portions 20 and 20 are alternately arranged. However, the first peripheral edge portions 10 and 10 and the second peripheral edge portions 20 and 20 are respectively disposed on two adjacent sides of the square. It may be arranged.

  FIG. 3 (2) shows a state in which four pieces of leather pieces 4 shown in FIG. 3 (1) are connected, and other pieces of leather pieces 4 having the same shape and different from the back side of the piece of leather 4 to each insertion port 11. The second peripheral edge portion 20 is inserted, and each insertion port 11 and the notches 22 and 22 are connected to each other to be connected.

Next, another embodiment of the present invention will be described with reference to FIG.
FIG. 4A is a front view of the leather piece 4, and the leather piece 4 includes a rectangular central portion 2, and a first peripheral edge portion 10 and a second peripheral edge portion 20, which are located on opposite short sides of the rectangle, respectively. It has become.
In the present embodiment, no peripheral edge is provided on the long sides of the rectangle facing each other. Therefore, it is effective when manufacturing a belt-shaped leather product.

Next, still another embodiment of the present invention will be described with reference to FIG.
Unlike the embodiments described so far, the joint width of the second peripheral edge portion 20 is the same as the length of the insertion slot 11, and the second peripheral edge portion 20 does not have the cuts 22 and 22.
According to this embodiment, there exists an effect that the operation | work which connects the leather pieces 4 becomes easy. On the other hand, although the connection strength between the leather pieces 4 is weakened, the connection can be reinforced by sticking a sheet-like nonwoven fabric to the back surface of the leather pieces 4 connected in large numbers.
