Abstract

To solve the problem that it is difficult to easily realize color mixing at the sides while maintaining advantages such as saving materials and simplifying the process in a braided basket made by raising it at 45 degrees. [Solution] A continuous tape-like material is used from the bottom to the side to form a basket at a 45-degree angle, and the tape-like material is intentionally folded inward and outward at the upper edge of the side, and the outward folded tape-like material is overlapped and woven downward along the outer surface of the side, making it easy to blend colors on the side.

Description

[Technical Field]

[0001] The present invention relates to a basket made by braiding colored tape-like materials. [Background technology]

[0002] Braiding is a technique in which flat tape-like materials are woven together in alternating vertical and horizontal directions, and this technique has traditionally been used to create items with a variety of patterns and shapes. Braided patterns are important not only for their practicality but also as design elements. In terms of design in braiding, in addition to the pattern created by the stitches, the color combination of the materials is also important. In particular, "mixed colors," in which the colors of the materials in the vertical and horizontal directions are different, are widely used as a method to visually emphasize the pattern created by the stitches.

[0003] Using this type of braiding technique, baskets have also traditionally been made by combining continuous braided surfaces into a three-dimensional structure, with rectangular parallelepiped baskets being particularly popular. One method for creating a three-dimensional rectangular parallelepiped basket through braiding is to raise the sides from the bottom braided surface, with two main methods: raising the sides in the direction of the bottom material's advance, or raising the sides at a 45-degree angle to the advance. [Prior art documents] [Non-patent literature]

[0004] [Non-Patent Document 1] Hiromi Matsuda, "Playing with Ajiro Weaving Patterns: Craft Band Bags and Baskets," Seibundo Shinkosha, March 20, 2020, Block Pattern Bag (Work 15) pp.76-78, Small Floral Pattern Bag (Work 16) pp.79-82 [Non-patent document 2] Craft Store ☆ Araudae Main Body Technique Prototype 8 (8): 7 Squares Part 2 Preparation for Incorporation, Incorporation: Horizontal Side, Incorporation: Vertical Side, Incorporation: Vertical and Horizontal, Incorporation: Bottom, Knitting Pattern and Position, [Searched May 28, 2025], Internet<URL:https: / / store.alaudae.jp / body-parts / prototype8-seven-squares-2.html> Summary of the Invention [Problem to be solved by the invention]

[0005] Among the above background art techniques, the method of raising the side sections from the braided surface that forms the bottom section at a 45-degree angle to the direction of travel has been widely used because it allows the bottom material to be used directly as a continuation of the side sections, eliminating the need for additional material, and offering the advantages of saving material and simplifying the work process.

[0006] However, with this 45-degree rise method, even if the material at the bottom is arranged in a mixed color pattern, the colors of the tape-like material extending in diagonal directions (+45 degrees and -45 degrees) over a wide area of ​​the side raised from the bottom are uniform in some parts, but the colors are not uniform in a specific number of positions corresponding to the width and depth of the basket, and areas of solid color (not mixed colors) appear alternately. As a result, the main part of the side as a whole is a mixture of mixed color patterns and solid color areas, which poses the problem of inferior design compared to a simple mixed color pattern, or of making it difficult to achieve the intended design.

[0007] Therefore, in order to achieve a highly attractive, uniform, interlaced color pattern on the main part of the side of a basket that is raised at a 45-degree angle, it is necessary to take measures such as correcting areas that would otherwise be a single color, or limiting the design to a single-color area or other area that is based on a mixture of colors in the vertical and horizontal directions.It is difficult to achieve a highly attractive, uniform, interlaced color pattern continuously over the entire area of ​​the side using a simple method.

[0008] To address this issue, conventional approaches to improving the design (uniform color blending) of the sides have been attempted, such as gluing tape-like materials of different colors together at the bottom, as in Non-Patent Document 1 (however, of the 11 relevant examples published in Non-Patent Document 1, only two advanced-level examples use this method of gluing together at the bottom; the other nine are designed to be single colors or with a mix of colors vertically and horizontally), or using more tape-like material than necessary and folding the excess to hide it or overlapping it on the side, as in Non-Patent Document 2. However, these methods not only require extra effort and materials, but also have problems such as uneven strength and thickness at the folded and glued / overlapped parts, which can lead to peeling or misalignment, and require skilled techniques for processes such as alignment and fixation to accurately achieve the intended pattern, especially in the case of complex knitting.

[0009] The present invention has been made in consideration of the problems with the prior art, and aims to provide a basket that maintains the advantages of 45-degree angle knitting, such as saving materials and simplifying the process, while eliminating the single-color areas mixed in with the main part of the side, and achieving a highly decorative, uniform mixed-color pattern in a simple manner throughout the entire side, including the edge and the part woven over it; ensures strength and a sense of unity in a simple manner; and can achieve color treatment of the entire side, including the area around the edge, in a simple manner, which becomes more difficult to apply as the weave becomes more complex, and requires special skilled techniques, regardless of the complexity of the weave, without requiring special skilled techniques. [Means for solving the problem]

[0010] In order to solve the above problems, the basket of the present invention is a rectangular parallelepiped basket having a bottom and a side, and a tape-like material constituting the side is raised at an angle of 45 degrees relative to the bottom, The tape-like material, which is continuous from the bottom, has a side portion that stands up at an angle of 45 degrees to the bottom, is folded back at its upper end to form a rim, and is further knitted downward along the outer surface or inner surface of the side portion, forming an integral structure. In this configuration, In the past, even if a tape-like material with the same color on both sides was used, only the color of the outer tape-like material was taken into consideration, and in the process of folding back to form the edge, the color of the already braided side was maintained only in the same direction. When forming the upper edge of the side portion, the tape-shaped material extending diagonally that constitutes the side portion is intentionally divided into a portion that is folded inward and a portion that is folded outward, and the tape-shaped material that is folded outward is overlapped and woven downward along the outer surface of the side portion, thereby achieving color mixing on the outside of the side portion (see claim 1).

[0011] In addition, the remaining tape-like material at the edge that has not been folded outward is folded inward and knitted downward along the inner surface of the side, resulting in a mixed color on the inside of the side as well (see claim 2).

[0012] Furthermore, the basket of the present invention is characterized in that the initial arrangement of the tape-like material on the flat braiding surface that serves as the base for braiding is configured to have a specific color arrangement according to the size of the finished basket, and the edges are formed so that the height of the side portions has a specific value depending on the size of the finished basket (see claim 3). [Effects of the Invention]

[0013] According to the present invention, it is now easy to separate the colors of the two tape-shaped materials that make up the side sections into a single color in each direction, which was previously difficult, and it is therefore easy to form highly decorative continuous patterns, such as checkerboard patterns or lattice patterns, over the entire side sections, which improves the aesthetic value of the product and greatly expands the degree of freedom in design.

[0014] Furthermore, the present invention utilizes the tape-shaped material raised from the bottom as it is for the sides, and applies existing techniques such as folding back the edges and layer knitting, eliminating the need for additional complex processes, thereby maintaining the advantages inherent in the 45-degree raising method, such as saving on materials and simplifying the work process.

[0015] Furthermore, instead of joining short strips of material separately, the continuous tape material from the bottom is folded back and overlapped, which enhances the sense of unity between the sides and edges, thereby increasing the strength of the entire basket. This makes it possible to provide a highly practical basket.

[0016] Furthermore, the manufacturing method and configuration of the present invention do not require special techniques or expertise, and the desired side color blending pattern can be easily formed by applying conventional edge processing. This is because the processing required to achieve the side color blending does not require special skills for alignment or fixation, as in the past, and can be achieved by applying conventional edge processing. This has the effect of enabling efficient production of products of consistent quality, regardless of the skill level of the manufacturer. [Brief explanation of the drawings]

[0018] Hereinafter, an embodiment of the present invention will be described. Since this invention relates to hand-knitted braided products, various numerical values ​​may be used in the specification and drawings to explain the configuration and effects of the invention, including continuous quantities such as angles, physical dimensions (length, width, etc.), specific locations, and positions of folds and overlaps, as well as counting values ​​such as the "number" of tape-like materials that are components and the "number of squares" made by orthogonal tape-like materials. The following points should be taken into consideration when interpreting these numerical values.

[0019] Of these values, those relating to angles, physical dimensions, specific locations, and positions of bending and overlapping are used as conceptual or ideal values, and some deviation from the stated values ​​is unavoidable due to variations in the manual work involved in actual production, the characteristics of the materials, the usage environment, etc.

[0020] On the other hand, numerical values ​​related to counts, such as the "number" of tape-like material components and the "number of squares" used to describe the size of the basket, are defined as discrete quantities in defining the structure of the invention. Of these counts, the "number" of tape-like material components and the "number of squares" (width and depth) related to the width and depth are strictly defined as integer values. However, the "number of squares" (height) related to the height can take on not only integer values ​​but also values ​​with a decimal point of 0.5 (e.g., 5.5 squares) due to its structure, and are strictly defined as the stated value.

[0021] In addition, in this invention, the overall size of the basket, such as its width, depth, and height, is expressed in units of "the number of squares made of the orthogonal tape-like material." For example, if there are 10 squares in the width direction, it is expressed as "10 squares in width." When the size is expressed in units of "squares" in this manner in the specification, it not only indicates the number of squares, but also refers to the approximate physical size it actually has. As with the numerical values ​​related to the continuous quantities above, this physical size may vary slightly due to manufacturing variations, etc.

[0022] Therefore, in interpreting the technical scope of the present invention, numerical values ​​relating to angles, physical dimensions, positions, and physical sizes expressed in units of "0 squares" are not strictly limited, but should be interpreted as including an allowable range of error or play from the stated numerical values, so long as they achieve substantially the same configuration, action, and effect. However, the "number" of tape-like materials as components, as well as numerical values ​​relating to counts in units of "0 squares" such as the number of widths and depths, and numerical values ​​relating to counts in units of "0 squares" such as the number of heights (including when the decimal part is 0.5), should be interpreted strictly as the stated values.

[0023] Next, the process for forming the bottom and sides of a basket according to one embodiment of the present invention will be described in detail with reference to the drawings. Here, the process will be described using an example in which a rectangular parallelepiped basket having a width of 10 squares, a depth of 5 squares, and a height of 15 squares is produced.

[0024] 1 to 7 are diagrams showing the steps for forming the bottom and sides of a basket according to this embodiment, as well as the completed basket. In addition, Figures 1 to 7 show "flat knitting" as an example of the weaving method, because flat knitting is the most basic and easy to understand of the weaving methods, and because the method for achieving the mixed colors on the sides, which is a main feature of this invention, can be applied regardless of the type of stitch (flat knitting, lattice knitting, etc.), and because it is sufficient to show that the relative positional relationship of the tape-like materials is uniquely determined by the size of the basket (unit: number of squares).

[0025] In Figure 1, 1 denotes the horizontally arranged tape-like material, and 2 denotes the vertically arranged tape-like material, and the overlapping portions of these are braided to form a flat braided surface. As will be described later, this initial braided surface is square, and will be folded and erected to form part of the bottom and sides. From now on, this initial braided surface will be referred to as the "base surface" regardless of the size of the basket.

[0026] In Figure 1, the number of strips of tape required is 15 in both the horizontal and vertical directions, which corresponds to the total of 10 squares, which is the width of the completed basket, and 5 squares, which is the depth. The color arrangement of the tape materials on this base surface is, for example, as shown in the figure, arranged in a mixed color scheme, with all horizontal tape materials (1 in Figure 1) being the first color and all vertical tape materials (2 in Figure 1) being the second color.

[0027] After the base surface is created, the tape-shaped material is raised vertically along fold position 3 shown in Figure 1, and the weaving of the sides begins. This allows a rectangular bottom 4, measuring 10 squares wide (corresponding to 3a in Figure 1) and 5 squares deep (corresponding to 3b in Figure 1), to be raised from a portion of the base surface where 15 strips of tape-shaped material intersect. The sides are formed by continuing to weave the tape-shaped material raised from bottom 4, completing the rectangular parallelepiped basket. Regardless of the type of stitch, the direction and position of the tape-shaped material are uniquely determined based on the unit "square." The sides of the completed basket are identified as four braided surfaces: a front surface 5a and a back surface 5c corresponding to the width, and a right surface 5b and a left surface 5d corresponding to the depth. In this embodiment, the height of the basket is 15 squares.

[0028] FIG. 2 is a perspective view showing the state in which the side portion has been knitted from FIG. 1, and FIG. 3 is a development view of the state shown in FIG. 2, opened from the bottom portion 4 and the front surface 5a. As shown in these figures, the bottom portion 4 is knitted to have mixed colors. However, the tape-like materials rising from the bottom portion 4 are arranged to extend at +45 degrees (corresponding to 7a and 7b in FIG. 2 and 7 in FIG. 3) and -45 degrees (corresponding to 8a and 8b in FIG. 2 and 8 in FIG. 3) relative to the edges of the bottom portion 4 on the side. Therefore, it is difficult to construct the entire side portion in a single color, i.e., to achieve mixed colors on the side, using a simple method. FIGS. 2 and 3 specifically illustrate a problem with the prior art, in that even if the color arrangement on the base surface is mixed colors, the colors of the tape-like materials extending in these diagonal directions blend together on the side.

[0029] The present invention employs "fold knitting" to solve the above-mentioned problems and achieve color blending at the sides. The specific steps are shown in Figures 4 and 5. Figures 4 and 5 show the process of folding back the tape-shaped material from the state knitted as shown in Figures 2 and 3 to form the edge and then continuing knitting. (The folding position and the method for determining the height of the finished basket will be described later.) In this embodiment, for example, if the target height of the finished basket is 7.5 square meters, the state shown in Figures 2 and 3 shows the state in which the sides are knitted up to a height of 15 square meters, which is twice the height before folding to achieve the finished height. This is because, as will be described later, when the tape-shaped material is folded back to form the final edge, the folded back tape-shaped material will have a length that reaches close to the bottom 4.

[0030] In the above explanation, to facilitate understanding, an example was given in which the tape-shaped material is folded back after the sides have been woven up to a height twice the desired finished height of the basket. However, in actual work, once the desired finished height of the basket is reached, the folding process can be started from that point, with that point being the edge position. Therefore, if the tape-shaped material is folded back at the position of folding line 9 shown in Figure 3 (7.5 squares above the bottom 4), the basket height will be 7.5 squares, and a basket of the desired height will be obtained.

[0031] Figures 4(1) to (6) show an example of the processing procedure for the outward folding portion (corresponding to locations 9a and 9c in Figure 3). As shown in Figures 4(1) to (3), first, the diagonal tape-shaped material appearing on the outside (corresponding to the -45-degree angle in this example) is lightly pulled out from the stitches (see Figure 4(1)), and then folded outward at 90 degrees to the direction of travel (see Figure 4(2)). Next, the folded tape-shaped material is placed on top of the other tape-shaped material that makes up the same side (corresponding to the +45-degree angle in this example), and knitted downward along the stitches until it approaches the bottom 4 (see Figure 4(3)).

[0032] Similarly, Figures 4(4) to 4(6) show an example of the processing procedure for the diagonal tape-shaped material (corresponding to the +45-degree direction in this example) that is overlapping the back of the part that is folded outward. This tape-shaped material is also folded outward by 90 degrees as shown in Figure 4(5), and as shown in Figure 4(6), it is placed on top of the other tape-shaped material that makes up the same side (corresponding to the -45-degree direction in this example), and knitted downward along the stitches until it is close to the bottom 4. By overlapping the folded tape-shaped material on top in this way, the color of the folded tape-shaped material appears on the surface of the part that is folded outward, and the tape-shaped material in the +45-degree direction and the tape-shaped material in the -45-degree direction each become the same color, that is, a mixed color is formed.

[0033] On the other hand, for the part folded inward (the part corresponding to the right surface 5b and left surface 5d shown as 12 in Figures 4 and 5), as shown in Figures 5(1) and 5(2), the tape-shaped material is folded inward at an angle of 90 degrees to the direction of travel, and similarly overlapped with the original stitch and woven downward along the stitch until it is close to the bottom 4. When folded inward, the inner surface of the basket becomes the surface of that part, but because the top and bottom of the tape-shaped material on the outer surface are inverted on this inner surface, intercoloring is also formed on the inner surface.

[0034] The end of the tape-like material that has been folded back from the edge and knitted up to near the bottom 4 is finished by cutting it on the back of the intersecting stitches. It is often finished near the center line of the bottom as shown in 6 in Figure 1, but it can also be finished at an appropriate position depending on the stitches and design.

[0035] In this way, by folding the tape-like material at the edges and doubling up the weave, the color of the folded tape-like material appears on the surface, eliminating the single-color areas that previously existed on some of the sides, and the tape-like material extending in the +45 degree and -45 degree directions becomes a single color in each direction.

[0036] In this folded over weave, where the outward folding configuration (see claim 1) is applied, the entire outer surface of the side becomes a mixed color, making it possible to form the intended mixed color pattern on the outer surface of the basket.

[0037] In addition, where the inward folding configuration (see claim 2) is applied, the entire inner surface of the side portion becomes a mixed color, making it possible to form a mixed color pattern on the inner surface of the basket as well.

[0038] As a result, according to the present invention, baskets with a variety of designs can be provided, such as those in which only the outer surface of the side is colored in a blended color, or those in which both the outer and inner surfaces are colored in a blended color, depending on the user's intentions.

[0039] Furthermore, since this folded knitting simply involves layering a tape-like material on top of the original stitches, the difficulty of the process is the same whether it is plain knitting or other knitting methods such as lattice knitting or various patterned knitting.

[0040] In the above explanation, the target finished height of the basket was described as 7.5 square meters, for example. However, if the invention could only produce baskets of a specific height, its practicality would be limited. It is important that the invention be able to produce baskets of various practical sizes while maintaining the intended design. Therefore, next, we will discuss the appropriate folding height and folding direction for achieving the intended blending color on the sides (outer and inner surfaces) of a basket of any width and depth, which is woven starting from a blending base surface.

[0041] In the case of a basket that starts weaving from a base surface with mixed colors, the height suitable for folding, that is, the number of heights at which mixed colors can be achieved on the sides by applying the above-mentioned "folded weaving" process, is a natural number multiple of ((number of widths + number of depths) ÷ 2), in units of squares.

[0042] The reason for this can be understood by unfolding the side section and observing the flow of the tape material. Figure 6 is a development diagram showing the state of a side section knitted to a height of 14 squares, with a width of 4 squares and a depth of 3 squares. As shown in this figure, the tape material rising from the bottom at +45 degrees (corresponding to 7 in Figure 6) and -45 degrees (corresponding to 8 in Figure 6) alternate colors in a cycle of the number of strips corresponding to the width and the number of strips corresponding to the depth. In this arrangement of the colored tape material, the same state as the line created by folding the bottom (corresponding to 3 in Figures 1 and 6), i.e., the state in which the first and second colors of all the tape material overlap one another, appears every 7 squares, which is (number of widths + number of depths) (lines 13b and 13d in Figure 6 are examples). (number of widths + number of depths) refers to the number of tape material initially arranged vertically and horizontally, and the cycle reaches the same state once.

[0043] Additionally, the state where the first and second colors of all the tape-shaped materials overlap vertically also occurs at a position halfway up, that is, at a height with a difference of ((number of widths + number of depths) ÷ 2) (lines 13a and 13c in Figure 6 are an example). This is halfway through the color change cycle, where the width and depth are swapped. Combining these, this means that every time the height increases by ((number of widths + number of depths) ÷ 2), a state where the first and second colors of all the tape-shaped materials overlap vertically will appear.

[0044] In the present invention, the line where this "state where the first and second colors of all the tape-shaped materials overlap vertically" appears is referred to as the "fold line." In the folded knitting of this embodiment (see Figures 4 and 5), the color is changed by folding the tape-shaped material outward (e.g., at location 13a-D) where it is desired to change the color of the outer surface (e.g., the front or back), and the outer color is maintained by folding the tape-shaped material inward (e.g., at location 13a-W) where it is desired to maintain the color of the outer surface (e.g., the right or left side). "A state where the first and second colors of all the tape-shaped materials overlap vertically" means that it is possible to choose whether to change or maintain the color of all the tape-shaped materials on the outer side surfaces.

[0045] If the height of this fold line is the edge of the basket, then by using the fold knitting method described above to fold the tape material 90 degrees and knit it twice, it is possible to apply a different overlapping color (the color of the folded tape material) only to the areas where the colors do not match, and it is possible to create a state in which the tape material extending in the +45 degree and -45 degree directions is a single color in each direction.The outer and inner surfaces of the sides are the front and back of the surface where the same tape material is braided above and below, and by folding the remaining part that was not folded outward due to the symmetry of the fold line inward, it is possible to finish both the outer and inner surfaces of the sides in mixed colors.

[0046] The folding direction (outside or inside) of this folding line is determined by whether the tape-shaped material is at a position corresponding to the width (corresponding to 3-W in Figure 6) or a position corresponding to the depth (corresponding to 3-D in Figure 6) at its original position on line 3 where it was folded up. In Figure 6, this is indicated by symbols such as "-W" and "-D." For example, for lines 13a, 13b, 13c, 13d, etc., whose height is a natural number multiple of ((number of widths + number of depths) ÷ 2), each tape-shaped material is indicated as a position corresponding to the width (e.g., 13a-W) or a position corresponding to the depth (e.g., 13a-D) depending on the position on line 3 from which it rose. Hereinafter, the tape-shaped material that rose from the position corresponding to the width on line 3 where it was folded up is identified as the "W position," and the tape-shaped material that rose from the position corresponding to the depth is identified as the "D position."

[0047] The positional relationship between each side surface and points D and W on the folding line can be expressed in words as follows: This shows the positional relationship of the tape-shaped material at the height where the edge is formed in the basket described in claim 3.

[0048] In the fold line where the height is a natural number multiple of (width + depth), point D is a tape-shaped material located the number of lines deep from the center of each of the left and right sides, and point W is a tape-shaped material located the number of lines wide from the center of each of the front and back sides, and matches the length of the sides of each side.

[0049] On the other hand, for a fold line whose height is a natural number multiple of (width number + depth number) minus ((width number + depth number) ÷ 2), point D is a tape-shaped material located the number of depth lines from the center of each of the front and back sides, and point W is a tape-shaped material located the number of width lines from the center of each of the left and right sides, resulting in a difference in the length of the sides of each side.

[0050] Then, when "fold knitting" using the fold line as the edge, the D point is folded outward and the W point is folded inward, or the D point is folded inward and the W point is folded outward (these folding processes correspond to the means for achieving the color mixing at the sides described in claims 1 and 2, and the description of the fold points corresponds to the positions described in claim 3).

[0051] The examples in Figures 4 and 5 show an example in which, in a 7.5 square folding line (corresponding to the latter type), point D (corresponding to 9a and 9c in Figure 3, and equivalent to 13a-D in Figure 6) is folded outward and point W (corresponding to a point other than 9a and 9c of 9 in Figure 3, and equivalent to 13a-W in Figure 6) is folded inward (this is an application example of the means described in claims 1 and 2).

[0052] In other words, being able to mix colors on the outside and inside at the same time means that not only can you fold point D outward and point W inward as in the examples of Figures 4 and 5, but you can also reverse this, i.e., fold point W outward and point D inward, to create mixed-color sides on both the outside and inside (this is the effect achieved by the means described in claims 1 and 2). For example, in the example of Figure 6, similar folding selection is possible for combinations of points D and W on other folding lines, such as points D and W on line 13b (height 7, first half type) and points D and W on line 13c (height 10.5, second half type).

[0053] Next, a method for setting the height to a value other than a natural number multiple of ((width number + depth number) ÷ 2) will be described with reference to Figures 6 and 7. Figure 7 shows a method for adjusting the fold line, which allows the entire side to have a mixed color, by replacing the color of the tape-like material at the end of the base surface.

[0054] Figure 6 shows the side section knitted up to 14 squares in the height direction, starting from bottom line 3, when unfolded. 14 in Figure 6 indicates the position one square higher from bottom line 3, and 15 in Figure 6 indicates the position two squares higher from bottom line 3. Looking at the state of these lines, it can be seen that for each square higher from bottom line 3, the area of ​​tape-like material where the two ends of each side of each of the four faces that make up the side section are crossed by one point, rather than two crosses of different colors. That is, in bottom line 3, all of the tape-like material is arranged in a two-color crossing arrangement, but in line 14, which is one square high, one cross at each end of each side is crossed by the same color, and in line 15, which is two squares high, two crosses at each end of each side are crossed by the same color.

[0055] This principle, that the area where the edges of the four sides that make up the side intersect with the same color increases depending on the height from the bottom, is based on the fact that by changing the color of the tape-like material at the edge of the base surface (described later), a color arrangement pattern different from line 3 on the bottom, such as lines 14 and 15 in Figure 6, is created around the bottom immediately after the side is raised, and this serves as the basis for adjusting the height at which an appropriate fold line appears that allows the entire side to have intersecting colors.

[0056] Figure 7 shows a method for changing the color of the base surface edge to adjust the height. Figure 7(1) shows the bottom color scheme when the base surface is completely woven with mixed colors. In this case, the bottom perimeter (the boundary between the basket bottom 4 and the side) immediately after the sides are raised is in the state of line 3 in Figure 6, i.e., all of the tape-shaped materials are arranged in a two-color cross-pattern. Figure 7(2) shows the case where the colors of one strip in the top row 1a and one strip in the bottom row 1b of the horizontal tape-shaped materials and one strip in the leftmost row 2a and one strip in the rightmost row 2b of the vertical tape-shaped materials are reversed from (1), which is called a "single-strand color change." The bottom perimeter immediately after the sides are raised from the base surface that has undergone this single-strand color change is in the state of line 14 in Figure 6, i.e., one strip at each end of each side is the same color. Figure 7(3) is an example of a "two-line color change" where two lines at each end are replaced with different colors. Immediately after the sides are raised from this color scheme, the bottom periphery will be in the state of line 15 in Figure 6, that is, the arrangement where two lines at each end of each side are the same color.

[0057] Comparing the developed views of Figures 7(1) to (3), it can be seen that compared to the case where there is no color change at the end of the base surface (Figure 7(1), the bottom periphery is in the state of 3 in Figure 6), the one color change (Figure 7(2), the bottom periphery is in the state of 14 in Figure 6) is one level lower, and the two color changes (Figure 7(3), the bottom periphery is in the state of 15 in Figure 6) are two levels lower, resulting in an appropriate folded line 13 that allows the entire side to be color-mixed.

[0058] In this way, to create a basket of the desired height, the number of steps (called N steps) by which the target height differs from the base height, which is a natural number multiple of ((width number + depth number) ÷ 2), is calculated in square units. Here, N is an integer greater than or equal to 0 and less than or equal to the depth number (the shorter of the width number and depth number). Then, based on this value of N, N strips of tape-like material are arranged in different colors from each of the vertical and horizontal ends of the base surface, thereby making it possible to create a basket with mixed-color sides that matches the desired height (this corresponds to the arrangement of the braided surface described in claim 3).

[0059] Here, when N is zero, it means that the color of the tape-shaped material at the end of the base surface is not replaced, which corresponds to the basic case when knitting of the base surface starts completely with mixed colors. The explanation using Figures 1 to 6 above has described the case when N is zero, that is, when knitting of the base surface starts completely with mixed colors, in which the appropriate fold height at which the side becomes mixed colors is a natural number multiple of ((number of widths + number of depths) ÷ 2) (corresponding to the configuration described in claim 3).

[0060] By forming the edge at this adjusted height (corresponding to 13 in Figure 7) and folding the tape material outward and inward as described above, baskets of various sizes required for practical purposes can be made with the sides (outer and inner surfaces) of mixed colors, although there are some limitations due to the combinations that can be made.

[0061] As explained in this embodiment, the basket of the present invention maintains the inherent advantages of 45-degree braided baskets, such as material savings and process simplification, while eliminating the monochromatic areas that were previously present in the main part of the side. It has been shown that a highly aesthetic, uniform, interlaced color pattern can be achieved throughout the entire side, including the edge and the overlapping weave. Furthermore, by using a color-changing method for the tape-like material at the end of the base surface, the height at which the fold lines appear can be adjusted, making it possible to manufacture baskets of various practical sizes and designs, including heights other than natural multiples of ((width + depth) ÷ 2). Furthermore, this manufacturing method, including fold braiding, does not require special expertise and can be applied to various weaving methods. [Example]

[0062] The following examples illustrate the application of the present invention to specific knitting methods and products. FIG. 8 shows an example in which the present invention is applied to a bag, braided by a method called three-strand jumping net braiding.

[0063] In this example, the basket structure of the invention was produced using a weaving method known as triple-skipping weaving. Triple-skipping weaving is a method of knitting in which three strips of tape-like material are bundled together and the crossing position is shifted while alternating between the top and bottom of every third strip. This is a popular weaving method that is also widely used in traditional bamboo crafts. Figure 8 shows an example in which the rectangular parallelepiped basket structure with mixed-color sides according to the present invention is applied to a bag using triple-skipping weaving. The bag according to this example further includes a handle portion that connects to the basket structure (see claim 4). [Explanation of symbols]
