[0012] The method for manufacturing a mesh fence described in claim 7 is the same as that described in claim 6, and is characterized in that the basic units of the repeating pattern of the pattern components of the first and second layers, which are repeated in the horizontal direction of the fence, are formed by bending wire material as pattern basic units, the first layer fence component members are formed by connecting a plurality of the pattern basic units, and the second layer fence component members are formed by connecting a plurality of the pattern basic units.

[0016] The method for manufacturing a mesh fence described in claim 11 is the method described in claim 9 or 10, and is characterized in that the pattern division unit has a shape such that the ends of the wire do not appear on the upper side of the fence in the vertical direction. [Effects of the Invention]

[0017] The mesh fence of the present invention is constructed by stacking first and second layer fence components, with the pattern components of the first and second layers overlapping to form a pattern. This allows for a higher wire density and higher pattern resolution than when a pattern is formed using only one layer of fence components, making it possible to create complex patterns. Furthermore, the wire density of the fence components per layer can be reduced, making it easy to manufacture.

[0018] When the first and second layer fence components are formed by bending wires in a plane without crossing them to form pattern elements, they can be easily manufactured using simple manufacturing machines that only have a bending function, compared to when the wires are crossed or twisted.

[0019] When the first and second layer fence components are formed in the same shape and the pattern components of the first layer and the second layer are overlapped with a misalignment to form a pattern, the first and second layer fence components can be made common, thereby reducing the number of types of parts and enabling the easy manufacture of mesh fences with complex patterns.

[0020] The pattern components of the first and second layers are each a honeycomb structure made up of regular hexagons of the same size, and when the honeycomb structure of the first layer and the honeycomb structure of the second layer are offset and overlapped so that the center of the regular hexagon of the first layer coincides with the vertex of the regular hexagon of the second layer, a complex design can be created that looks as if there are many cubes.When the honeycomb structure is oriented so that two parallel sides of the regular hexagon extend vertically along the fence, it is possible to easily create a complex design with excellent designability that produces the visual effect of cubes stacked diagonally in a staircase pattern.

[0021] The method for manufacturing a mesh fence of the present invention involves forming the first and second layer fence components to be the same shape and stacking them so that the pattern components of the first and second layers are offset from each other.This allows the fence components to be standardized, reducing the number of different parts and making it easy to manufacture mesh fences with complex patterns.

[0022] When wire is bent to form the basic unit of a repeating pattern that is repeated across the fence for the first and second layer pattern components, and the first and second layer fence components are formed by connecting a plurality of pattern basic units, the number of types of parts can be reduced and a mesh fence with a complex pattern can be manufactured more easily.

[0023] When the pattern components of the first and second layers are honeycomb structure shapes made up of regular hexagons of the same size lined up, and the basic pattern unit is a honeycomb structure shape in which regular hexagons are lined up in a row in the vertical direction of the fence, it is possible to easily manufacture a fence with a complex design that looks as if it has many cubes.

[0024] If the repeating patterns that are repeated across the fence among the pattern components of the first and second layers are divided so that they can be formed by alternatingly combining wire rods of the same shape in a symmetrical shape, and these divided pattern division units are formed by bending the wire rod, and the first and second layer fence components are manufactured by alternately connecting multiple pattern division units in a symmetrical shape, it is possible to obtain parts with fewer bends in the wire rod than when manufacturing the above-mentioned pattern basic units, and this means that production can be done more quickly if the manufacturing equipment is one in which welding takes less time.

[0025] If the pattern components of the first and second layers are honeycomb structures made up of regular hexagons of the same size, and the pattern division units are half the length of the wire rods that form a row of regular hexagons in the vertical direction of the honeycomb structure fence, it is possible to easily manufacture a fence with a complex design that looks as if it has many cubes.If the pattern division units are shaped so that the ends of the wire rods do not appear on the upper side of the fence in the vertical direction, it is possible to manufacture the fence without creating welds at the top.

[0027] Hereinafter, embodiments for carrying out the present invention will be described in detail, but the scope of the present invention is not limited to these embodiments.

[0028] [First embodiment] Figure 1 shows a front view of the mesh fence 1, Figure 2 shows an explanatory diagram for explaining the configuration of the pattern 5 of the mesh fence 1, Figure 3(a) shows a front view of the first layer fence component 2 of the mesh fence 1, Figure 3(b) shows a front view of the second layer fence component 3 of the mesh fence 1, and Figure 4 shows a left side view of the mesh fence 1. The configuration of a mesh fence 1 to which the present invention is applied will be described. The mesh fence 1 to which the present invention is applied is formed by stacking a first layer fence component 2 and a second layer fence component 3, the first layer fence component 2 having a first layer pattern component 22 formed by wire material 12, the second layer fence component 3 having a second layer pattern component 23 formed by wire material 13, and the first layer fence component 2 and the second layer fence component 3 being stacked together, with the first layer pattern component 22 and the second layer pattern component 23 overlapping to form a pattern 5. It is preferred that the first layer fence component 2 has wires 12 bent within a plane without crossing each other to form the first layer pattern element 22, and the second layer fence component 3 has wires 13 bent within a plane without crossing each other to form the second layer pattern element 23. The first layer fence component 2 and the second layer fence component 3 are preferably formed in the same shape, and the first layer fence component 2 and the second layer fence component 3 are stacked so that the first layer pattern component 22 and the second layer pattern component 23 are offset and overlap to form the pattern 5. The first-layer pattern component 22 and the second-layer pattern component 23 each have a honeycomb structure formed by arranging regular hexagons of the same size, and it is preferable that the first-layer honeycomb structure component 22 and the second-layer honeycomb structure component 23 are overlapped with a shift so that the center of the regular hexagon in the first layer coincides with the vertex of the regular hexagon in the second layer. The honeycomb structure components 22 and 23 are preferably arranged so that two parallel sides of the regular hexagon extend in the vertical direction of the fence (up and down direction of the fence). The specific details will be explained below.

[0029] As shown in Figure 1, mesh fence 1 is made up of a first layer of fence component 2 and a second layer of fence component 3 stacked together, with pattern 5 formed across the entire surface by wires 12 of first layer fence component 2 and wires 13 of second layer fence component 3. Wires 12 and 13 are made of reinforcing bars or the like. As shown in this example, mesh fence 1 may also have reinforcing horizontal bars 31, 34 made of reinforcing bars or the like, and horizontal bars 32, 33 for fixing the posts, if necessary.

[0030] Figure 2 shows a partially enlarged front view illustrating the configuration of the pattern 5 of the mesh fence 1. Figure 2(a) shows a partially enlarged front view of the first-layer fence component 2. As shown in the figure, the first-layer fence component 2 has a honeycomb structure 22 (an example of a first-layer pattern component 22 of the present invention) in which wires 12 are bent in a plane without crossing each other, and regular hexagons of the same size are lined up without gaps.

[0031] Figure 2(c) shows a partially enlarged front view of the second-layer fence component 3. As shown in the figure, the second-layer fence component 3 has a honeycomb structure 23 (an example of a second-layer pattern component 23 of the present invention) in which wires 13 are bent in a plane without crossing each other, and regular hexagons of the same size are lined up without gaps. The regular hexagons of the honeycomb structure 22 of the first layer and the regular hexagons of the honeycomb structure 23 of the second layer are formed to be the same size. Wires 12 and 13 are made of the same material and have the same diameter.

[0032] The honeycomb structure shapes 22, 23 are formed by bending the wires 12, 13 in a plane without crossing each other, and can be easily manufactured by a simple manufacturing machine having only a bending function, compared to the case where the wires 12, 13 are crossed or twisted.

[0033] As shown in Figure 2(b), the first layer honeycomb structure shape 22 and the second layer honeycomb structure shape 23 are overlapped with each other in a misaligned manner so that the center of the regular hexagon of the first layer honeycomb structure shape 22 coincides with the vertex of the regular hexagon of the second layer honeycomb structure shape 23, thereby forming pattern 5. Pattern 5 is a complex design that appears three-dimensional, as if there were many cubes. Such a complex design can be easily formed by stacking the first layer fence component 2 and the second layer fence component 3.

[0034] As shown in Figure 2, the honeycomb structure shapes 22 and 23 are formed with two parallel sides of a regular hexagon extending in the vertical direction of the fence, so that the pattern 5 has an excellent design that produces a three-dimensional visual effect in which cubes appear to be stacked in a staircase pattern in the diagonal up and down direction. Note that the honeycomb structure shapes 22 and 23 may also be designed so that the two parallel sides of the regular hexagon are aligned horizontally.

[0035] Pattern 5 is a design that produces a three-dimensional visual effect that looks like a large number of cubes are drawn, but because the first and second layer pattern components (honeycomb structure shapes) 22, 23 are layered, the fence has a depth of two layers (the step between wire 12 and wire 13), and this depth can create a visual effect that makes the three-dimensional design look even more three-dimensional.

[0036] Figure 3(a) shows a front view illustrating the structure of a first-layer fence component 2, and Figure 3(b) shows a front view illustrating the structure of a second-layer fence component 3. As shown in Figure 3(a), the first-layer fence component 2 has, as an example, a honeycomb structure 22 formed over the entire surface using wires 12. Furthermore, as shown in Figure 3(b), the second-layer fence component 3 has a honeycomb structure 23 formed over the entire surface using wires 13.

[0037] When the first-layer fence component 2 shown in Figure 1(a) is turned upside down (or rotated upside down), it becomes the second-layer fence component 3 shown in Figure 1(b). In other words, the first-layer fence component 2 and the second-layer fence component 3 are formed to have the same shape. Therefore, the first-layer pattern component (honeycomb structure shape) 22 and the second-layer pattern component (honeycomb structure shape) 23 are formed to have the same shape.

[0038] FIG. 4 shows a left side view of the mesh fence 1. FIG. 4(a) shows an enlarged left side view of the upper part of the mesh fence 1, surrounded by a dashed circle, and FIG. 4(b) shows an enlarged left side view of the lower part of the mesh fence 1, surrounded by a dashed circle. As shown in FIG. 4, the mesh fence 1 is formed by stacking a first-layer fence component 2 and a second-layer fence component 3. The first-layer fence component 2 and the second-layer fence component 3, which are inverted (or rotated), are stacked with a vertical offset. By stacking the first-layer fence component 2 and the second-layer fence component 3 with a vertical offset, the first-layer honeycomb structure shape 22 and the second-layer honeycomb structure shape 23 are stacked with a vertical offset, as shown in FIG. 2.

[0039] By forming the first layer fence component 2 and the second layer fence component 3 in the same shape, the number of types of parts can be reduced, and the mesh fence 1 can be manufactured simply and quickly.

[0040] FIG. 5 shows a left side view of a modified mesh fence 1. FIG. 5(a) shows an enlarged left side view of the upper part of the mesh fence 1, surrounded by a dashed circle, and FIG. 5(b) shows an enlarged left side view of the lower part of the mesh fence 1, surrounded by a dashed circle. As shown in the figure, the upper and / or lower side surfaces of the mesh fence 1 may be formed, for example, in a "L" shape. In this case, the upper and lower parts of the first-layer fence component 2 and the second-layer fence component 3 may be formed by bending them in a "L" shape. Furthermore, although not shown, the upper and / or lower side surfaces of the mesh fence 1 may be formed in a shape bent into an arc.

[0041] The first layer fence component 2 and the second layer fence component 3 may be colored the same color or different colors.

[0042] Although the example in which the pattern 5 is formed over the entire surface of the mesh fence 1 has been described, the pattern 5 may also be arranged on only a part of the mesh fence 1. In this case, the portions other than the pattern 5 may be formed into any shape, such as by leaving the wires 12, 13 straight without bending, or by changing the bending pattern to create a different design.

[0043] The first layer of fence components 2 and the second layer of fence components 3 can be stacked in any one of the following ways, or a combination of these, such that the first layer of pattern components 22 and the second layer of pattern components 23 are stacked in a shifted manner according to the shape of the pattern 5: inverting the second layer of fence components 3 upside down, rotating them upside down, shifting them up and down, shifting them left and right, flipping them left and right, and shifting them diagonally.

[0044] In the example described above, the first-layer fence-constituting member 2 and the second-layer fence-constituting member 3 are formed to have the same shape and are stacked with a misalignment as shown in Fig. 4, but the first-layer fence-constituting member and the second-layer fence-constituting member may also be stacked without a misalignment so that pattern 5 appears. In other words, when the first-layer fence-constituting member and the second-layer fence-constituting member are stacked so that their outer shapes (peripheral edges) exactly match, the pattern elements (honeycomb structure shapes) 22, 23 of the first and second layers may be stacked with a misalignment as shown in Fig. 2. In this case, the first-layer fence-constituting member and the second-layer fence-constituting member may have different shapes.

[0045] Next, a method for manufacturing a mesh fence to which the present invention is applied will be described. Note that, in the following, the same components as those already described will be assigned the same reference numerals, and detailed description thereof will be omitted.

[0046] FIG. 6 shows an explanatory diagram of the manufacturing method for the mesh fence. The construction of a method for manufacturing a mesh fence to which the present invention is applied will be described. The method for manufacturing a mesh fence is characterized in that a first layer fence component 2 and a second layer fence component 3 are stacked together, and a pattern 5 is formed by overlapping a first layer pattern element 22 of the first layer fence component 2 with a second layer pattern element 23 of the second layer fence component 3, and the first layer fence component 2 and the second layer fence component 3 are formed to have the same shape, and the first layer fence component 2 and the second layer fence component 3 are stacked together so that the first layer pattern element 22 and the second layer pattern element 23 are offset from each other and overlap. It is preferable that the basic unit of the repeating pattern of the first and second layer pattern elements 22, 23 repeated in the horizontal direction of the fence (left and right direction of the fence) is formed by bending wire material as a pattern basic unit 7, the first layer fence component 2 is formed by connecting a plurality of pattern basic units 7, and the second layer fence component 3 is formed by connecting a plurality of pattern basic units 7. It is preferable that the pattern components 22, 23 of the first and second layers are honeycomb structure shapes 22, 23 in which regular hexagons of the same size are arranged, and that the pattern basic unit 7 is a shape of the honeycomb structure shapes 22, 23 in which regular hexagons are arranged in a row in the vertical direction of the fence. The specific details will be explained below.

[0047] In the method of manufacturing a mesh fence, first, as shown in Figure 6(a1), wire 12 is bent to form a pattern basic unit 7. Similarly, as shown in Figure 6(a2), wire 13 is bent to form a pattern basic unit 7. Wire 12 and wire 13 are similar, and there is no distinction between the pattern basic units 7 shown in Figures 6(a1) and 6(a2), and both are formed to the same shape. Figure 6(a2) shows the pattern basic unit 7 shown in Figure 6(a1) in a state where it is upside down (rotated upside down).

[0048] The pattern basic unit 7 is, for example, the smallest pattern repeated in the horizontal direction of the fence of the honeycomb structure shapes 22, 23. For example, the pattern basic unit 7 is formed in a shape in which regular hexagons are lined up in a row in the vertical direction of the fence (a shape in which regular hexagons are lined up with one side connected to each other) so that two parallel sides of the regular hexagons of the honeycomb structure shapes 22, 23 face the vertical direction of the fence. In this example, the pattern basic unit 7 is symmetrical, but may be asymmetrical depending on the design. It is preferable that the pattern basic unit 7 is formed by bending the wires 12 (13) in a plane without crossing each other.

[0049] Next, as shown in Figure 6(b1), a plurality of pattern basic units 7 are lined up consecutively in the horizontal direction and connected to form the first-layer fence component member 2. The number of pattern basic units 7 to be connected can be adjusted to match the length of the first-layer fence component member 2. This figure shows the pattern basic units 7 connected partway through the first-layer fence component member 2. Similarly, as shown in Figure 6(b2), a plurality of pattern basic units 7 are lined up consecutively in the horizontal direction and connected to form the second-layer fence component member 3. The number of pattern basic units 7 to be connected can be adjusted to match the length of the second-layer fence component member 3. This figure shows the pattern basic units 7 connected partway through the second-layer fence component member 3. Adjacent pattern basic units 7 are connected by welding, for example.

[0050] There is no distinction between the first-layer fence component 2 and the second-layer fence component 3 shown in Figures 6(b1) and 6(b2), and both are formed to the same shape. The second-layer fence component 3 in Figure 6(b2) is shown as the first-layer fence component 2 shown in Figure 6(b1) turned upside down (rotated upside down).

[0051] Next, as shown in Figure 6(c), the first layer fence component 2 and the second layer fence component 3 are stacked and connected by welding or the like so that the first layer honeycomb structure shape 22 and the second layer honeycomb structure shape 23 are offset and overlapped to form the pattern 5 described above, and the mesh fence 1 is completed.

[0052] The mesh fence 1 may be manufactured by stacking a first-layer fence component 2 completed after all of the pattern basic units 7 have been connected, and a second-layer fence component 3 completed after all of the pattern basic units 7 have been connected, or the mesh fence 1 may be manufactured by sequentially connecting the pattern basic units 7 of the second-layer fence component 3 (the second-layer fence component 3 before completion) so that they are stacked on top of the first-layer fence component 2 (the first-layer fence component 2 before completion) as the pattern basic units 7 are being connected. For example, the mesh fence 1 may be manufactured by alternately stacking and connecting the pattern basic units 7 of the first and second layers of fence component 2, and then connecting the pattern basic units 7 of the second-layer fence component 3 on top of them, and extending them horizontally.

[0053] Next, another method for manufacturing a mesh fence to which the present invention is applied will be described.

[0054] FIG. 7 shows an explanatory diagram of another method for manufacturing the mesh fence 1. The construction of a method for manufacturing a mesh fence to which the present invention is applied will be described. The method for manufacturing the mesh fence 1 is characterized in that the repeating patterns of the first and second layer pattern components 22, 23 that are repeated across the fence are divided so that they can be formed by alternately combining wire rods of the same shape in a symmetrical shape, and these divided pattern division units 8 are formed by bending the wire rods 12, 13, the first layer fence component 2 is formed by alternately connecting the plurality of pattern division units 8 in a symmetrical shape, and the second layer fence component 3 is formed by alternately connecting the plurality of pattern division units 8 in a symmetrical shape. A symmetrical shape refers to a shape that is symmetrical along a line, such as left-right or top-bottom, or that is symmetrical in rotation (point symmetry). It is preferable that the pattern components 22, 23 of the first and second layers are honeycomb structure shapes in which regular hexagons of the same size are lined up, and the pattern division unit 8 is a portion of the honeycomb structure shapes 22, 23 in which the length of the wire material forming a shape in which regular hexagons are lined up in a row in the vertical direction of the fence is half. The pattern division unit 8 is preferably shaped so that the ends of the wires do not appear on the upper side in the vertical direction of the fence. This will be explained in detail below.

[0055] In the method of manufacturing a mesh fence, first, as shown in Figure 7(a1), wire 12 is bent to form pattern division units 8. Similarly, as shown in Figure 7(a2), wire 13 is bent to form pattern division units 8. Wire 12 and wire 13 are similar, and there is no distinction between the pattern division units 8 shown in Figures 7(a1) and 7(a2), and both are formed in the same shape. Figure 7(a2) shows the pattern division unit 8 shown in Figure 7(a1) upside down.

[0056] The pattern dividing units 8 are formed in a shape that, when two of them are connected symmetrically, can form regular hexagons lined up in a row in the vertical direction of the fence of the honeycomb structure shape 22. In this example, the pattern dividing units 8 are, for example, a section of wire material that is half (1 / 2) the length of the wire material that forms the pattern basic unit 7 shown in Figure 6(a1), which is a shape in which regular hexagons are lined up in a row in the vertical direction of the fence, that is, the shape of a repeating pattern. The shape of the pattern dividing unit 8 may be any shape as long as a section of wire material that is half the length of the wire material that forms the pattern basic unit 7 is selected.

[0057] By connecting the pattern division unit 8 shown in Figure 7(a1) with the pattern division unit 8 inverted upside down as shown in Figure 7(b1), that is, by alternately combining and connecting the pattern division units 8 to form a symmetrical shape (vertically symmetrical), a shape is formed in which the regular hexagons of the honeycomb structure shape 22 are lined up in a row in the vertical direction of the fence (a shape in which regular hexagons are lined up with one side connected to each other), as shown in Figure 7(c1).

[0058] As shown in Figure 7(d1), a first-layer fence component 2 having a honeycomb structure shape 22 is formed by combining and connecting multiple pattern division units 8 alternately in a symmetrical manner. The number of pattern division units 8 to be connected can be adjusted to match the length of the first-layer fence component 2. This figure shows the state in which the pattern division units 8 have been connected partway through the first-layer fence component 2.

[0059] Similarly, the pattern division unit 8 shown in Figure 7(a2) and the pattern division unit 8 upside down shown in Figure 7(b2) are connected, that is, alternately combined and connected in a symmetrical manner, to form a shape in which the regular hexagons of the honeycomb structure shape 23 are lined up in a row in the vertical direction of the fence (a shape in which regular hexagons are lined up with one side connected to each other), as shown in Figure 7(c2). As shown in Figure 7(d2), a second-layer fence component 3 having a honeycomb structure shape 23 is formed by alternately combining and connecting multiple pattern division units 8 in a symmetrical manner. The number of pattern division units 8 to be connected can be adjusted to match the length of the second-layer fence component 3. This figure shows the state in which the pattern division units 8 are connected partway through the second-layer fence component 3.

[0060] There is no distinction between the first-layer fence component 2 shown in Fig. 7(d1) and the second-layer fence component 3 shown in Fig. 6(d2), and both have the same shape. The second-layer fence component 3 in Fig. 7(d2) is drawn as if the first-layer fence component 2 shown in Fig. 7(d1) was turned upside down.

[0061] Next, as shown in Figure 7(e), the first layer fence component 2 and the second layer fence component 3 are stacked upside down and connected by welding or the like so that the first layer honeycomb structure shape 22 and the second layer honeycomb structure shape 23 are offset and overlapped to form the pattern 5 described above, and the mesh fence 1 is completed.

[0062] In this example, as shown in Figure 7(e), the upper left 41 and lower left 42 of the mesh fence 1 do not have a wire rod for one side of the cube that makes up the pattern 5. Therefore, a wire rod for one side may be added and connected to the upper left 41 and lower left 42, or only the shape of the wire rod that forms the left side may be replaced with a wire rod that has one side in the upper left 41 (lower left 42).

[0063] In this example, the wire rods on one side of the cubes that make up the pattern 5 protrude from the upper right portion 43 and lower right portion 44 of the mesh fence 1. Therefore, the upper right portion 43 and lower right portion 44 may be cut out, or the shape of the wire rod that forms the right side may be replaced with wire rod that does not have the upper right portion 43 (lower right portion 44) portion.

[0064] The mesh fence 1 may be manufactured by stacking a first-layer fence component 2 completed after all of the pattern division units 8 have been connected, and a second-layer fence component 3 completed after all of the pattern division units 8 have been connected, or the mesh fence 1 may be manufactured by sequentially connecting the pattern division units 8 of a second-layer fence component 3 (a second-layer fence component 3 before completion) so that the pattern division units 8 are stacked on top of the first-layer fence component 2 (the first-layer fence component 2 before completion) in the middle of connecting the pattern division units 8. For example, the mesh fence 1 may be manufactured by alternately stacking and connecting the pattern division units 8 of the first and second layers of fence component 2, and then connecting the pattern division units 8 of the second-layer fence component 3 on top of them, and extending them horizontally.

[0065] The pattern division units 8 are connected to each other by welding. Because the upper side of the mesh fence 1 is easily touched and easily visible, it is preferable that no welds be created on the upper side. For this reason, as shown in FIG. 7(a1), it is preferable that the shape of the pattern division unit 8 is such that the ends of the pattern division units 8 are not located within the sides of the hexagon that appears at the end of the upper vertical side of the fence. For example, the upper end of the pattern division unit 8 shown in FIG. 7(a1) and the upper end of the pattern division unit 8 shown in FIG. 7(b1) are connected by welding at weld 51 shown in FIG. 7(c1), and therefore do not appear on the upper side of the mesh fence 1.

[0066] If the welding points (connections) between pattern divided units 8 may be formed on the upper side of the mesh fence 1, the shape of the pattern divided unit 8 may be such that the pattern basic unit 7 shown in Figure 6(a) is divided into two vertically from the middle. In this case, the first layer of fence-component members 2 and the second layer of fence-component members 3 can be formed by connecting the pattern divided units 8 alternately and symmetrically.

[0067] [Second embodiment] In the first embodiment, an example was shown in which the pattern elements 22 and 23 of the first and second layers forming the pattern 5 have a honeycomb structure in which regular hexagons are arranged, but in the second embodiment, an example of a different shape is shown.

[0068] Figure 8 shows a manufacturing method for a mesh fence 1a to which the present invention is applied. This figure shows an example of a shape in which diamonds are arranged without gaps as the first and second layer pattern elements 22a, 23a. Furthermore, this example shows an example in which semicircular shapes are arranged at the top and bottom of the first and second layer pattern elements 22a, 23a.

[0069] The method of manufacturing the mesh fence 1a begins with bending wires 12 and 13 to form pattern division units 8a, as shown in Figures 8(a1) and 8(a2). Wires 12 and 13 are similar, and there is no distinction between the pattern division units 8a shown in Figures 8(a1) and 8(a2), and both have the same shape.

[0070] As shown in Figures 8(a1) and 8(b1), the pattern division units 8a are formed so that when two of them are connected facing each other symmetrically (rotationally symmetrically), they form the shape of the pattern basic unit 7a shown in Figure 8(c1). The pattern basic unit 7a is the basic unit of the repeating pattern of the pattern elements 22 and 23 in the horizontal direction of the fence, and is a diamond structure shape 22a in which diamonds are lined up in a row in the vertical direction of the fence. In this example, the upper and lower parts of the pattern basic unit 7a are formed in semicircular shapes. The same is true for Figures 8(a2) to 8(c2).

[0071] As shown in FIG. 8(a1), the pattern divided unit 8a is formed in a shape such that its end is not positioned above the pattern basic unit 7a so that no welded portion (connected portion) is generated at the top.

[0072] As shown in Figure 8(d1), a first-layer fence component 2a is formed by alternately connecting multiple pattern division units 8a in a symmetrical manner. This figure shows the state in which the pattern division units 8 have been connected partway through the first-layer fence component 2a. Similarly, as shown in Figure 8(d2), a second-layer fence component 3a is formed by alternately connecting multiple pattern division units 8a in a symmetrical manner. The first-layer fence component 2a shown in Figure 8(d1) and the second-layer fence component 3a shown in Figure 8(d2) have the same shape.

[0073] Next, as shown in Figure 8(e), first-layer fence component 2a and second-layer fence component 3a are stacked with a left-right offset and connected by welding or the like to complete mesh fence 1a. As a result, first-layer pattern component 22a and second-layer pattern component 23a are stacked with a left-right offset, forming pattern 5a on mesh fence 1a.

[0074] It is also possible to manufacture the mesh fence 1a by first manufacturing the pattern basic units 7a shown in Figures 8(c1) and 8(c2) without using the pattern division units 8a shown in Figures 8(a1) and 8(a2).

[0075] The shapes of the pattern elements 22, 23 (22a, 23a) of the first and second layers are arbitrary. For example, the pattern elements of the first and second layers may be an arrangement of arbitrary geometric shapes such as triangles, rectangles, and polygons. The pattern elements of the first and second layers do not have to be figures that can be tessellated, which fill a plane without gaps in a specific pattern. For example, the pattern elements of the first and second layers may be shapes such as circles, ellipses, polygons, curves, and bent lines, or may be an arrangement of multiple different shapes. When the pattern elements of the first and second layers have the same shape, the offset method (shift direction and distance) is arbitrary. The shapes of the pattern elements of the first and second layers may be different. When the shapes of the pattern elements of the first and second layers are different, the pattern elements of the first and second layers may be overlapped without offset or with offset depending on the design. By overlapping the pattern components of the first and second layers, a pictorial design of, for example, animals, characters, people, vehicles, landscapes, architecture, natural objects, man-made objects, etc. may be constructed as a pattern.
