Description

[Technical Field]

[0001] This invention relates to a piece of fabric that can be used to form a three-dimensional fabric product by connecting a large number of flat pieces together, and in particular to a three-dimensional fabric product that can be formed using only pieces of fabric of the same shape. [Background technology]

[0002] In Patent Document 1 (Japanese Patent No. 4480791), the applicant of the present application has disclosed a piece of fabric comprising a hexagonal central portion and first and second peripheral portions alternately positioned on the periphery of the central portion, wherein the first peripheral portion and the second peripheral portion share one side of the hexagon and the first peripheral portion shares two vertices of the hexagon, and a first cut is provided at the boundary between the first peripheral portion and the central portion, the first cut being shorter than the length of the side and longer than one-fourth the length of the side, and The present invention discloses a piece of cloth characterized in that it has second cuts at both ends of the side at the boundary line between the first and second cloth pieces, the second cuts being equal to or slightly longer than half the length of the side minus the length of the first cut, and the three first cuts can be fitted and connected by matching the respective cuts with the second cuts of three other different pieces of cloth of the same shape, and the three second cuts can be fitted and connected by matching the respective cuts with the first cuts of three other different pieces of cloth of the same shape.

[0003] The fabric pieces are highly functional and can be used to make clothing, accessories, hats, etc. However, when making these three-dimensional objects, sewing or other fastening methods are required to partially achieve the desired shape, and it has been difficult to make a three-dimensional object by connecting only the fabric pieces. Therefore, in order to make a three-dimensional object, it was first necessary to connect the fabric pieces to make a flat sheet, cut the flat sheet to prepare the necessary parts, and then connect these parts using sewing or other fastening methods.

[0004] In Patent Document 2 (Japanese Patent No. 7037853), the applicant of the present application has disclosed a base cloth piece connectable to a basic cloth piece, the basic cloth piece being a cloth piece consisting of a hexagonal central portion and first and second peripheral portions alternately positioned around the periphery of the central portion, the first peripheral portion and the second peripheral portion sharing one side of the hexagon, the boundary between the first peripheral portion and the central portion having a first cut that is shorter than the length of the side and longer than one-quarter of the length of the side, and the boundary between the second peripheral portion and the central portion having second cuts that are equal to or slightly longer than one-half the length of the side minus the length of the first cut from both ends of the side, the three first cuts being matched with the second cuts of three other different cloth pieces of the same shape, and the three second cuts being connectable by fitting them together, The second notch can be fitted and connected to the first notch of three different cloth pieces of the same shape as the three cloth pieces by matching the notches, and the central part of the base cloth piece has a shape in which triangular parts formed by three adjacent vertices of a hexagon of the same shape as the basic cloth piece are lined up without any gaps around it, and the periphery of the central part has a first peripheral part with a first notch and a second peripheral part with a second notch of the same shape as the basic cloth piece, and the first notches of the base cloth piece can be fitted and connected to the second notches of the basic cloth piece by matching the respective notches, and the second notches of the base cloth piece can be fitted and connected to the first notches of the basic cloth piece by matching the respective notches, and a base cloth piece characterized in that when a large number of basic cloth pieces are connected to the base cloth piece, gaps are formed between the centers of adjacent basic cloth pieces.

[0005] Three-dimensional objects made using the base cloth pieces do not require any fixing means such as sewing, which is normally required when making three-dimensional objects, so it is possible to make various three-dimensional objects simply by connecting cloth pieces without any sewing skills, but three-dimensional objects can only be made by combining them with base cloth pieces of a different shape from the basic cloth piece, and it is not possible to make three-dimensional objects simply by connecting cloth pieces of the same shape.

[0006] [Patent Document 1] Patent No. 4480791 [Patent Document 2] Patent No. 7037853 Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention aims to produce a three-dimensional object by simply connecting pieces of fabric of the same shape, without using any fixing means such as sewing, when connecting pieces of fabric to produce a three-dimensional object. [Means for solving the problem]

[0008] A fabric product using a piece of fabric consisting of a hexagonal central portion and first and second peripheral portions alternately positioned around the periphery of the central portion, wherein the first peripheral portion and second peripheral portion share one side of the hexagon, and the boundary between the first peripheral portion and the central portion has a first cut that is shorter than the length of the side and longer than 1 / 4 of the length of the side, and the boundary between the second peripheral portion and the central portion has second cuts that are equal to or slightly longer than 1 / 2 of the length of the side minus the length of the first cut from both ends of the side, and the three first cuts are aligned with the second cuts of three other different pieces of fabric of the same shape. The three second cuts can be fitted and connected with the first cuts of three different pieces of cloth that are different from the three pieces of cloth but have the same shape, by matching the respective cuts and fitting them together; by fitting the first cuts and second cuts of the pieces of cloth together, the multiple pieces of cloth are connected together into an equilateral triangular sheet as a whole; two different pieces of cloth are placed at the locations corresponding to the three vertices of the equilateral triangle; and by matching the respective cuts and second cuts of the adjacent first cuts and second cuts located at the vertices of the two different pieces of cloth together and fitting them together, the three sides of the equilateral triangular sheet rise at right angles.

[0009] It is preferable that the sheet be formed into a bag-like shape as a whole by connecting a number of fabric pieces along three sides of the equilateral triangular sheet rising at right angles.

[0010] It is preferable that a different sheet having the same shape as the equilateral triangular sheet is connected to the opening of the bag-shaped fabric product to close the opening. The hexagon is preferably a regular hexagon. [Effects of the Invention]

[0011] The fabric product of the present invention does not require any fastening means such as sewing, which is normally required when producing a three-dimensional object, and therefore makes it possible to produce a three-dimensional object simply by connecting pieces of fabric of the same shape, even without sewing skills, etc. Furthermore, because it can be produced using only pieces of fabric of the same shape, it is sufficient to prepare only one type of blade die for producing the pieces of fabric, thereby improving production efficiency and reducing production costs.

[0013] Hereinafter, an embodiment of a fabric product according to the present invention will be described with reference to the drawings, but first, a piece of fabric used in the fabric product will be described. FIG. 1 is a front view of a piece of cloth, which is composed of a regular hexagonal central portion 2 and first peripheral portions 10, 10, 10 and second peripheral portions 20, 20, 20 positioned alternately around the periphery of the central portion 2. By alternately arranging the first peripheral portions 10, 10, 10 and the second peripheral portions 20, 20, 20, it becomes possible to connect the cloth pieces in a plane almost infinitely. The first peripheral edge portion 10 and the second peripheral edge portion 20 are each integral with the central portion 2 by sharing one side of the regular hexagon of the central portion 2 .

[0014] A first cut 11 is provided at the boundary between the first peripheral edge portion 10 and the central portion 2, the cut 11 being shorter than the length of the shared side and longer than 1 / 4 of the length of that side. In addition, notches 22, 22 are provided at the boundary between the second peripheral edge portion 20 and the central portion 2 from both ends of the shared side, with a length equal to or slightly longer than half the length of the side minus the length of the first notch. Here, "slightly longer" means excluding a length that would not be able to maintain the connection strength described below.

[0015] As will be described later, the first incision 11 and the second incisions 22, 22 are fitted together to connect the cloth pieces together. Therefore, in order to maintain the connection strength between the cloth pieces, the lengths of the first incision 11 and the second incisions 22, 22 must be within the above range. The preferred length of the first incision 11 is 1 / 4 to 3 / 4 of the length of the shared side, and a length of about 1 / 2 of the length of the shared side is particularly preferred. The widths of the first slit 11 and the second slits 22, 22 depend solely on the thickness of the cloth piece. The first (second) slits 11, 22 penetrate the cloth piece from the front to the back.

[0016] To be more specific about the length of the first incision 11 and the length of the second incisions 22, 22, although this will depend on the material, thickness, and application of the piece of fabric, if a bag is made from a piece of fabric that is about 1.2 mm thick, and the length of one side of the regular hexagon in Figure 1 is, for example, 10 mm, then the length of the first incision 11 is 5 mm and the length of the second incisions 22, 22 is 2.5 mm.

[0017] A regular hexagon is the optimum shape for the central portion 2. A regular hexagon allows fabric pieces to be connected to form a flat surface with no gaps, allows for freedom in direction when connecting the fabric pieces, and is also excellent in terms of connection strength.

[0018] Even if the shape is not a regular hexagon, a point-symmetric hexagon is preferable in that it allows for a planar configuration without gaps without being restricted by the direction of connection. Examples of point-symmetric hexagons include a regular hexagon that is flattened in one direction (a hexagon with all six sides of equal length and two different interior angles instead of 120 degrees), a hexagon with all 120 degree interior angles and two different side lengths, and a hexagon with two different side lengths and interior angles. However, depending on the application of the product, it must be taken into consideration that the connection strength of the short connecting sides of the above hexagons is weaker than that of the long connecting sides.

[0019] There are no particular restrictions on the size of the cloth pieces, although this will depend largely on the properties and size of the product they will make up. For example, in the case of a regular hexagon, it is preferable that the length of each piece be in the range of 6 mm to 900 mm.

[0020] There are no particular limitations on the shapes of the first peripheral edge portion 10 and the second peripheral edge portion 20, but consideration should be given to the ease of manufacture and other manufacturing conditions for the pieces of fabric, as well as the design of the first (second) peripheral edge portions 10, 20. That is, the shape of the first (second) peripheral edge portions 10, 20 determines the design of the back (and in some cases, the front) of the product made from the pieces of fabric. Furthermore, the back of the piece of fabric will have a significant impact on the functionality of the garment, such as its heat retention, moisture retention, and feel against the skin, so the material and thickness of the piece of fabric, as well as the shape, should be determined according to the application to which the piece of fabric will be used.

[0021] In this embodiment, the shape of the first (second) peripheral edge portion 10, 20 is triangular, but it may also be rectangular, trapezoidal, semicircular, semi-elliptical, etc. In the case of a triangular shape, in addition to making it easier to connect the fabric pieces together, there is an advantage in that the first peripheral edge portion 10 and the second peripheral edge portion 20 do not overlap, making it easier to manufacture a thin three-dimensional object.

[0022] The length of the seam width, which forms the boundary between the first peripheral edge portion 10 or the second peripheral edge portion 20 and the central portion 2, is equal to the length of the side of the hexagon. If the seam width is shorter than the length of the side of the hexagon, the connection strength may decrease. On the other hand, it is difficult to obtain a seam width longer than the length of the side of the hexagon from a single piece of fabric.

[0023] There are no particular restrictions on the seam length (the length perpendicular to the seam width) of the first peripheral edge portion 10 and the second peripheral edge portion 20, but the length must be long enough so that the fabric pieces do not easily come apart when pulled. If the length of one side of the regular hexagon shown in Figure 2 is 10 mm, the seam length will be approximately 6 mm. It is also possible to make the seam length 6 mm or longer, taking into consideration the design of the fabric pieces and the fabric product.

[0024] The thickness of the fabric pieces is determined by the material and the product to which they are applied. Generally, it is thought that things that connect easily have weak strength, but conversely, they also tend to separate easily, so this point must be taken into consideration. Generally, the thickness of the fabric pieces is preferably 5 mm or less, and more preferably about 0.1 to 3 mm.

[0025] In the present invention, the material for the cloth piece may be any sheet-like material that is flexible enough to be bent, and examples thereof include various woven and nonwoven fabrics, lace, felt, etc. made from natural fibers, nylon, polyester, other synthetic fibers, synthetic resins, synthetic rubber, etc. Leather, suede, etc. may also be used. Among these, nonwoven fabric, felt, leather, suede, etc. are excellent materials in that the edges do not fray after the material sheet is cut and cutting operations using a laser cutter or embossing are easy.

[0026] The pieces of cloth described above can be connected in a flat manner by fitting the first notch 11 of the first peripheral edge 10 with the second notches 22, 22 of the second peripheral edge 20 of another piece of cloth, thereby producing various cloth products. More specifically, by folding the second notches 22, 22 of the second peripheral portion 20 and inserting them into the first notch 11 of the first peripheral portion 10 of another piece of cloth, and then fitting the first notch 11 and the second notches 22, 22 together, multiple pieces of cloth can be connected in a flat manner to produce various cloth products.

[0027] Next, the fabric product of the present invention will be described. Figure 2 shows a state in which a number of pieces of fabric are connected together to form an equilateral triangular sheet as a whole. The equilateral triangular sheet is connected by matching and fitting the first incisions 11 (and second incisions 22, 22) of one piece of fabric with the second incisions 22, 22 (and first incisions 11) of another piece of fabric of the same shape. Two different pieces of cloth, A1, A2, B1, B2, C1, and C2, are placed at the three vertices of the equilateral triangle. In this embodiment, one side of the equilateral triangle is made up of nine pieces of cloth, but there is no particular limit to the number of pieces of cloth that make up one side of the equilateral triangle, as long as two different pieces of cloth are placed at the locations corresponding to the three vertices of the equilateral triangle.

[0028] FIG. 3 shows the state in which three sides of the equilateral triangular sheet shown in FIG. 2 are raised at right angles. In Figure 2, for each of two different pieces of cloth A1, A2, B1, B2, C1, and C2 located at the three vertices of an equilateral triangle, the adjacent first incisions 11 and second incisions 22, 22 located at the apexes of the two pieces of cloth are aligned and fitted together to connect the three sides of the equilateral triangular sheet at right angles, as shown in Figure 3. In other words, while two pieces of cloth are normally connected in plan by fitting the first incisions 11 and second incisions 22, 22 together, only one side of the hexagon in the center 2 of the pieces of cloth is connected in a plane, in the part where the pieces are to be raised at a right angle, it is possible to connect them three-dimensionally by connecting two adjacent sides of the hexagon in the center 2 of the pieces of cloth.

[0029] According to the fabric product of the present invention, a three-dimensional object can be produced simply by joining pieces of fabric of the same shape, without using any fastening means such as sewing. Furthermore, since it can be produced using only pieces of fabric of the same shape, it is sufficient to prepare only one type of cutting die for producing the pieces of fabric, thereby improving production efficiency and reducing production costs. In this embodiment, a fabric product can be produced in which three sides of an equilateral triangular sheet stand at right angles, making it suitable for producing dish-shaped fabric products such as accessory trays.

[0030] FIG. 4 shows a fabric product formed into a bag-like shape as a whole by connecting pieces of fabric along three sides of the equilateral triangular sheet shown in FIG. 3 that stands at right angles. By fitting the first notch 11 of the first peripheral edge 10 of one piece of cloth with the second notches 22, 22 of the second peripheral edge 20 of another piece of cloth along the three sides that rise at right angles in Figure 3, multiple pieces of cloth can be connected to form a bag-like overall shape.

[0031] As shown in Figure 3, if you look at the three upright sides of the equilateral triangular sheet, you will see that the pieces of fabric are connected in a horizontal row, so the three sides can be formed into a flat surface in the same way as when making a flat sheet. Since it is just a matter of connecting pieces of fabric of the same shape in the same way as when making a flat sheet, it is extremely easy to make. In this embodiment, a fabric product formed into a bag shape as a whole can be produced, and therefore can be used for a variety of purposes such as bags, pots, dustbins, etc.

[0032] Figure 5 shows a fabric product in which the opening of the bag-shaped fabric product shown in Figure 4 has been closed by joining a different sheet of the same shape as the equilateral triangular sheet shown in Figure 2 to the opening. The method for producing the equilateral triangular sheet for closing the opening is as described above, but in this embodiment, the sheet shown in Figure 2 is produced in a state where the positional relationship between the first incisions 11 and the second incisions 22 on the fabric piece is reversed from left to right. Then, after raising the three sides of the equilateral triangular sheet at right angles, a fabric product with a closed opening can be produced by joining it to the opening. The fabric product of this embodiment can be used for cushions and various other purposes.

[0033] The fabric product of the present invention is made up of only the above-mentioned identically shaped pieces of fabric, and a three-dimensional object can be produced by simply joining the pieces of fabric together without using any fastening means such as sewing. In particular, in the past, in order to form a three-dimensional raised shape, it was necessary to use a fastening means such as sewing, or to use a piece of fabric with a different shape from the piece of fabric in question. However, according to the present invention, it is possible to form a three-dimensional raised shape using only the identically shaped pieces of fabric, without using any fastening means such as sewing.
