Summary of the Invention
Problems to be Solved by the Invention
[0004] In a mesh fence, since it is necessary to bend the wire rods constituting the fence surface to form a pattern, there is a problem that it is difficult to provide a complicated pattern.
[0005] The present invention has been made to solve the above problems, and an object thereof is to provide a mesh fence that can provide a complicated pattern and can be easily manufactured.
Means for Solving the Problems
[0011] Claim 1The method for manufacturing a mesh fence described herein is a method for manufacturing a mesh fence in which a first layer of fence components and a second layer of fence components are stacked, and a pattern is formed by overlapping the first layer pattern components of the first layer of fence components and the second layer pattern components of the second layer of fence components, wherein the first layer of fence components and the second layer of fence components are formed in the same shape, and the first layer of fence components and the second layer of fence components are stacked such that the first layer pattern components and the second layer pattern components overlap with an offset. The repeating pattern of the first and second layers, which is repeated in the horizontal direction of the fence, is divided so that it can be formed by symmetrically combining wires of the same shape alternately, and these divided pattern division units are formed by bending the wires, and the ends of the wires of the pattern division units are such that they do not appear on the upper side in the vertical direction of the fence, and the first layer fence component is formed by symmetrically connecting a plurality of the pattern division units alternately, and the second layer fence component is formed by symmetrically connecting a plurality of the pattern division units alternately. It is characterized by the following:
[0015] Claim 2 The method for manufacturing a mesh fence described in Claim 1 The present invention relates to the invention described above, wherein the pattern components of the first and second layers are honeycomb structures formed by arranging regular hexagons of the same size, and the pattern division unit is characterized in that the wires forming a shape in which the regular hexagons are arranged in a line in the vertical direction of the fence are half the length of the wires within the honeycomb structure. [Effects of the Invention]
[0017] The mesh fence of the present invention is constructed by laminating a first layer of fence components with a second layer of fence components, so that the pattern components of the first layer and the pattern components of the second layer overlap to form a pattern. This allows for a higher density of wires and a higher resolution of the pattern compared to when a pattern is formed with only one layer of fence components, thus enabling the creation of complex patterns. Furthermore, since the density of wires in each layer of fence components can be reduced, it can be manufactured simply.
[0018] When the first and second layer fence components are formed by bending wires in a plane without intersecting them, they can be easily manufactured using simple manufacturing machinery that only has a bending function, compared to cases where the wires are intersected or twisted.
[0019] If the first and second layer fence components are formed in the same shape, and the pattern components of the first and second layers overlap with a slight offset to form a pattern, the first and second layer fence components can be standardized, reducing the number of parts and allowing for the easy manufacture of mesh fences with complex patterns.
[0020] The pattern components of the first and second layers are honeycomb structures made up of regular hexagons of the same size. When the honeycomb structures of the first and second layers are offset and overlapped so that the centers of the regular hexagons in the first layer coincide with the vertices of the regular hexagons in the second layer, a complex design can be formed that looks as if there are many cubes. When the honeycomb structures are arranged so that two parallel sides of the regular hexagons extend in the vertical direction of the fence, a complex design with excellent aesthetic appeal can be easily formed, creating a visual effect that makes it look as if cubes are stacked in a staircase-like fashion in the diagonal vertical direction.
[0021] The present invention provides a method for manufacturing a mesh fence in which the first and second layers of fence components are formed in the same shape, and the first and second layers of fence components are laminated so that the pattern components of the first and second layers overlap with a slight offset. This method allows for the commonization of fence components, thus reducing the number of parts and enabling the easy manufacture of mesh fences with complex patterns.
[0022] When the basic units of the repeating patterns that are repeated horizontally in the fence for the pattern components of the first and second layers are formed by bending wire materials as pattern basic units, and the fence components of the first and second layers are formed by connecting multiple pattern basic units, the number of types of parts can be reduced, and mesh fences with complex patterns can be manufactured more easily.
[0023] If the pattern components of the first and second layers are honeycomb structures made up of regular hexagons of the same size, and the basic pattern unit is a honeycomb structure in which regular hexagons are arranged in a line in the vertical direction of the fence, then a fence with a complex design that looks as if it were made up of many cubes can be easily manufactured.
[0024] When the repeating patterns in the horizontal direction of the fence, which are part of the pattern components of the first and second layers, are divided so that they can be formed by symmetrically combining wires of the same shape alternately, and these divided pattern division units are formed by bending the wires, and the fence components of the first and second layers are manufactured by symmetrically connecting multiple pattern division units alternately, it is possible to create parts with fewer wire bends than when manufacturing the basic pattern units as described above, and thus manufacturing can be done more quickly with manufacturing equipment that can do so in a shorter time using welding.
[0025] If the pattern elements of the first and second layers are honeycomb structures formed by arranging regular hexagons of the same size, and the pattern division unit is a section of wire that forms a shape of regular hexagons arranged in a row in the vertical direction of the honeycomb structure fence, then a fence with a complex design that looks as if it has many cubes can be easily manufactured. If the end of the wire in the pattern division unit does not appear on the upper side in the vertical direction of the fence, then it can be manufactured without creating welding points on the top of the fence.

Embodiments for Carrying Out the Invention
[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] FIG. 1 shows a front view of the mesh fence 1, FIG. 2 shows an explanatory view for explaining the configuration of the pattern 5 of the mesh fence 1, FIG. 3(a) shows a front view of the first-layer fence component 2 of the mesh fence 1, FIG. 3(b) shows a front view of the second-layer fence component 3 of the mesh fence 1, and FIG. 4 shows a left side view of the mesh fence 1. The configuration of the mesh fence 1 to which the present invention is applied is described. The mesh fence 1 to which the present invention is applied is formed by laminating the first-layer fence component 2 and the second-layer fence component 3. The first-layer fence component 2 has a first-layer pattern component 22 formed by the wire 12, and the second-layer fence component 3 has a second-layer pattern component 23 formed by the wire 13. The first-layer fence component 2 and the second-layer fence component 3 are laminated, and the first-layer pattern component 22 and the second-layer pattern component 23 overlap to form the pattern 5. Preferably, the first layer of fence components 2 is formed by the wires 12 bending in a plane without intersecting, creating the first layer of pattern components 22, and the second layer of fence components 3 is formed by the wires 13 bending in a plane without intersecting, creating the second layer of pattern components 23. It is preferable that the first layer fence component 2 and the second layer fence component 3 are formed in the same shape, and that the first layer fence component 2 and the second layer fence component 3 are stacked such that the pattern component 22 of the first layer and the pattern component 23 of the second layer overlap with a slight offset to form the pattern 5. The first layer pattern component 22 and the second layer pattern component 23 are each honeycomb structures made up of regular hexagons of the same size, and it is preferable that the first layer honeycomb structure 22 and the second layer honeycomb structure 23 are offset and overlapping so that the centers of the regular hexagons in the first layer coincide with the vertices of the regular hexagons in the second layer. It is preferable that the honeycomb structures 22 and 23 are provided with two parallel sides of the regular hexagons extending in the vertical direction of the fence (up and down direction of the fence). The following provides a detailed explanation.
[0029] As shown in Figure 1, the mesh fence 1 is constructed by laminating a first layer of fence components 2 and a second layer of fence components 3, and a pattern 5 is formed across the entire surface by the wires 12 of the first layer of fence components 2 and the wires 13 of the second layer of fence components 3. The wires 12 and 13 are made of reinforcing bars or the like. As shown in this example, the mesh fence 1 may also be provided with reinforcing horizontal bars 31, 34 and horizontal bars 32, 33 for fixing support posts, as needed.
[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 shape 22 (an example of the first layer pattern component 22 of the present invention) in which the wires 12 are bent in a plane without intersecting, and regular hexagons of the same size are arranged 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 shape 23 (an example of the second layer pattern component 23 of the present invention) in which the wires 13 are bent in a plane without intersecting, and regular hexagons of the same size are arranged without gaps. The regular hexagons of the first layer honeycomb structure shape 22 and the regular hexagons of the second layer honeycomb structure shape 23 are formed to the same size. The wires 12 and 13 are made of the same material and have the same diameter.
[0032] By forming the honeycomb structures 22 and 23 by bending the wires 12 and 13 in a plane without them intersecting, they can be easily manufactured using a simple manufacturing machine that only has a bending function, compared to cases where the wires 12 and 13 are intersected or twisted.
[0033] As shown in Figure 2(b), the pattern 5 is formed when the first honeycomb structure shape 22 and the second honeycomb structure shape 23 overlap with a slight offset, such that the center of the regular hexagon of the first honeycomb structure shape 22 coincides with the vertices of the regular hexagon of the second honeycomb structure shape 23. The 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 fence component 2 and the second 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 the pattern 5 has a three-dimensional visual effect that makes it appear as if cubes are stacked in a staircase-like manner in the diagonal vertical direction, resulting in a design with excellent aesthetic appeal. Alternatively, the honeycomb structure shapes 22 and 23 could be designed with two parallel sides of a regular hexagon oriented horizontally.
[0035] Pattern 5 is a design that creates a three-dimensional visual effect, appearing to depict numerous cubes. However, because the first and second layered pattern components (honeycomb structure shapes) 22 and 23 are stacked, the fence gains a depth equivalent to two layers (a difference in height between wires 12 and 13). This depth can create a visual effect that makes the three-dimensional design appear even more three-dimensional.
[0036] Figure 3(a) shows a front view illustrating the structure of the first layer fence component 2, and Figure 3(b) shows a front view illustrating the structure of the second layer fence component 3. As shown in Figure 3(a), the first layer fence component 2 has a honeycomb structure 22 formed across its entire surface by wires 12, as an example. Also, as shown in Figure 3(b), the second layer fence component 3 has a honeycomb structure 23 formed across its entire surface by wires 13.
[0037] When the first layer fence component 2 shown in Figure (a) is inverted (or rotated vertically), it becomes the state of the second layer fence component 3 shown in Figure (b). In other words, the first layer fence component 2 and the second layer fence component 3 are formed to the same shape. Therefore, the pattern component (honeycomb structure shape) 22 of the first layer and the pattern component (honeycomb structure shape) 23 of the second layer are formed to the same shape.
[0038] Figure 4 shows a left side view of the mesh fence 1. Figure (a) shows an enlarged upper left side view of the mesh fence 1 enclosed by a dashed circle, and Figure (b) shows an enlarged lower left side view of the mesh fence 1 enclosed by a dashed circle. As shown in Figure 4, the mesh fence 1 is formed by stacking a first layer of fence components 2 and a second layer of fence components 3. The first layer of fence components 2 and the second layer of fence components 3, which are inverted (or rotated) vertically, are stacked with a vertical offset. By stacking the first layer of fence components 2 and the second layer of fence components 3 with an offset in this way, the honeycomb structure shape 22 of the first layer and the honeycomb structure shape 23 of the second layer overlap with an offset, as shown in Figure 2, to form the pattern 5.
[0039] By forming the first layer fence component 2 and the second layer fence component 3 with the same shape, the number of parts can be reduced, allowing for simple and rapid manufacturing of the mesh fence 1.
[0040] Figure 5 shows a modified left side view of the mesh fence 1. Figure (a) shows an enlarged left side view of the upper part of the mesh fence 1 enclosed by a dashed circle, and Figure (b) shows an enlarged left side view of the lower part of the mesh fence 1 enclosed by a dashed circle. As shown in the figure, the upper and / or lower sides of the mesh fence 1 may be formed in a shape that is bent, for example, in a "V" 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 "V" shape. Although not shown, the upper and / or lower sides of the mesh fence 1 may also be formed in an arc shape.
[0041] The first layer fence component 2 and the second layer fence component 3 may be colored the same color, or they may be colored different colors.
[0042] Although an example has been described in which the pattern 5 is formed on the entire surface of the mesh fence 1, the pattern 5 may also be placed on only a part of the mesh fence 1. In this case, the parts other than the pattern 5 can be formed into any shape, such as by making the wires 12 and 13 straight without bending them, or by changing the bending pattern to create a different design.
[0043] The method of stacking the first layer fence component 2 and the second layer fence component 3 is such that the pattern component 22 of the first layer and the pattern component 23 of the second layer overlap with the first layer fence component 2 in a shifted manner according to the shape of the pattern 5. This can be done by stacking the second layer fence component 3 relative to the first layer fence component 2 by inverting it vertically, rotating it vertically, shifting it vertically, shifting it horizontally, inverting it horizontally, and shifting it diagonally, or by any combination thereof.
[0044] In the example described in Figure 4, the first layer fence component 2 and the second layer fence component 3 are formed with the same shape and are stacked with a slight offset. However, the pattern 5 may also be formed so that it appears even when the first and second layers fence components are stacked without any offset. In other words, when the first and second layers fence components are stacked so that their outer shapes (peripheral edges) exactly match, the pattern components (honeycomb structure shapes) 22 and 23 of the first and second layers may be formed to overlap with a slight offset, as shown in Figure 2. In this case, the first and second layers fence components may have different shapes.
[0045] Next, a method for manufacturing a mesh fence to which the present invention is applied will be described. In the following, components similar to those already described will be denoted by the same reference numerals, and detailed descriptions will be omitted.
[0046] Figure 6 shows an explanatory diagram of the manufacturing method for a mesh fence. The configuration of a method for manufacturing a mesh fence to which the present invention is applied is described below. A method for manufacturing a mesh fence is a method for manufacturing a mesh fence in which a first layer of fence components 2 and a second layer of fence components 3 are stacked, and a pattern 5 is formed when the first layer pattern component 22 of the first layer of fence components 2 and the second layer pattern component 23 of the second layer of fence components 3 overlap, characterized in that the first layer of fence components 2 and the second layer of fence components 3 are formed in the same shape, and the first layer of fence components 2 and the second layer of fence components 3 are stacked in such a way that the first layer pattern component 22 and the second layer pattern component 23 overlap with an offset. It is preferable that the basic units of the repeating patterns that are repeated in the horizontal direction (left-right direction of the fence) of the pattern components 22 and 23 of the first and second layers are formed by bending wire material as pattern basic units 7, the fence component member 2 of the first layer is formed by connecting a plurality of pattern basic units 7, and the fence component member 3 of the second layer is formed by connecting a plurality of pattern basic units 7. The pattern components 22 and 23 of the first and second layers are honeycomb structures 22 and 23 formed by arranging regular hexagons of the same size, and the basic pattern unit 7 is preferably a honeycomb structure 22 and 23 in which regular hexagons are arranged in a single row in the vertical direction of the fence. The following provides a detailed explanation.
[0047] The manufacturing method for the mesh fence is as follows: First, as shown in Figure 6(a1), wire 12 is bent to form a basic pattern unit 7. Similarly, as shown in Figure 6(a2), wire 13 is bent to form a basic pattern unit 7. Wire 12 and wire 13 are the same, and there is no distinction between the basic pattern units 7 shown in Figure 6(a1) and Figure 6(a2); both are formed into the same shape. Figure 6(a2) shows the basic pattern unit 7 shown in Figure 6(a1) inverted (rotated vertically).
[0048] Pattern basic unit 7 is, as an example, the smallest pattern that is repeated horizontally in the fence direction of the honeycomb structure shapes 22 and 23. Pattern basic unit 7 is formed in a shape in which regular hexagons are arranged in a line vertically in the fence direction (a shape in which regular hexagons are connected by one side) so that two parallel sides of the regular hexagons of the honeycomb structure shapes 22 and 23 face the vertical direction of the fence. In this example, pattern basic unit 7 is symmetrical, but it may be asymmetrical depending on the design. It is preferable that pattern basic unit 7 is formed by bending the wires 12 (13) in a plane without intersecting.
[0049] Next, as shown in Figure 6(b1), multiple pattern basic units 7 are arranged and connected in a continuous horizontal direction to form the first layer of fence components 2. The number of pattern basic units 7 connected should match the length of the first layer of fence components 2. The figure shows the state where the pattern basic units 7 are connected up to partway along the first layer of fence components 2. Similarly, as shown in Figure 6(b2), multiple pattern basic units 7 are arranged and connected in a continuous horizontal direction to form the second layer of fence components 3. The number of pattern basic units 7 connected should match the length of the second layer of fence components 3. The figure shows the state where the pattern basic units 7 are connected up to partway along the second layer of fence components 3. Adjacent pattern basic units 7 are connected, for example, by welding.
[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); 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) inverted (rotated vertically).
[0051] Next, as shown in Figure 6(c), the first layer of fence components 2 and the second layer of fence components 3 are stacked and connected by welding or the like so that the honeycomb structure shape 22 of the first layer and the honeycomb structure shape 23 of the second layer overlap with a slight offset, so that the aforementioned pattern 5 is formed, and the mesh fence 1 is completed.
[0052] The mesh fence 1 may be manufactured by stacking the completed first layer fence component 2, which has all its basic pattern units 7 connected, with the completed second layer fence component 3, which has all its basic pattern units 7 connected. Alternatively, the mesh fence 1 may be manufactured by sequentially connecting the basic pattern units 7 of the second layer fence component 3 (the second layer fence component 3 before completion) so that it is stacked on top of the first layer fence component 2 (the first layer fence component 2 before completion), which is still in the process of connecting the basic pattern units 7. For example, the mesh fence 1 may be manufactured by alternately stacking and connecting the basic pattern units 7 of the first and second layers, extending them horizontally, by connecting the basic pattern units 7 of the first layer fence component 2 to each other and then connecting the basic pattern units 7 of the second layer fence component 3 on top of them.
[0053] Next, another method for manufacturing a mesh fence to which the present invention is applied will be described.
[0054] Figure 7 shows an explanatory diagram of another method for manufacturing the mesh fence 1. The configuration of a method for manufacturing a mesh fence to which the present invention is applied is described below. The manufacturing method for the mesh fence 1 is characterized by dividing the repeating patterns of the first and second layer pattern components 22 and 23, which are repeated in the horizontal direction of the fence, so that they can be formed by symmetrically combining wires of the same shape alternately, forming these divided pattern division units 8 by bending wires 12 and 13, forming the first layer fence component 2 by symmetrically connecting multiple pattern division units 8 alternately, and forming the second layer fence component 3 by connecting multiple pattern division units 8 alternately in a symmetrical manner. A symmetrical shape refers to a shape that exhibits line symmetry, such as left-right symmetry or up-down symmetry, or rotational symmetry (point symmetry). The pattern components 22 and 23 of the first and second layers are honeycomb structures formed by arranging regular hexagons of the same size, and the pattern division unit 8 is preferably a portion of the wires that form a shape in which regular hexagons are arranged in a line in the vertical direction of the fence, within the honeycomb structures 22 and 23, where the wires are half the length. It is preferable that the pattern division unit 8 has a shape in which the ends of its wires do not appear on the upper side in the vertical direction of the fence. The details will be explained below.
[0055] The manufacturing method for the mesh fence is as follows: First, as shown in Figure 7(a1), wire 12 is bent to form a pattern division unit 8. Similarly, as shown in Figure 7(a2), wire 13 is bent to form a pattern division unit 8. Wire 12 and wire 13 are the same, and there is no distinction between the pattern division units 8 shown in Figure 7(a1) and Figure 7(a2); both are formed to the same shape. Figure 7(a2) shows the pattern division unit 8 shown in Figure 7(a1) inverted vertically.
[0056] The pattern division unit 8 is shaped such that when two are connected symmetrically, it can form a row of regular hexagons in the vertical direction of the fence of the honeycomb structure shape 22. In this example, the pattern division unit 8 is, as an example, a portion of the wire that forms the basic pattern unit 7 shown in Figure 6(a1), which is a repeating pattern with a row of regular hexagons in the vertical direction of the fence, and is half the length of the wire. The shape of the pattern division unit 8 can be any shape as long as a portion of the wire that is half the length of the wire that forms the basic pattern unit 7 is selected.
[0057] By connecting the pattern division unit 8 shown in Figure 7(a1) with the inverted pattern division unit 8 shown in Figure 7(b1), that is, by alternately combining and connecting the pattern division units 8 to form a symmetrical shape (vertically symmetrical shape), a shape is formed as shown in Figure 7(c1), in which the regular hexagons of the honeycomb structure shape 22 are arranged in a line in the vertical direction of the fence (a shape in which regular hexagons are connected by one side).
[0058] As shown in Figure 7(d1), the first layer of fence components 2 having a honeycomb structure 22 is formed by connecting multiple pattern division units 8 alternately in a symmetrical manner. The number of pattern division units 8 to be connected should match the length of the first layer of fence components 2. The figure shows the state where the pattern division units 8 have been connected up to partway along the first layer of fence components 2.
[0059] Similarly, the pattern division unit 8 shown in Figure 7(a2) and the inverted pattern division unit 8 shown in Figure 7(b2) are connected, that is, they are combined and connected alternately in a symmetrical manner, to form a shape in which the regular hexagons of the honeycomb structure shape 23 are arranged in a line in the vertical direction of the fence (a shape in which regular hexagons are connected by one side), as shown in Figure 7(c2). As shown in Figure 7(d2), by combining and connecting multiple pattern division units 8 alternately in a symmetrical manner, a second layer of fence components 3 having the honeycomb structure shape 23 is formed. The number of pattern division units 8 to be connected should match the length of the second layer of fence components 3. The figure shows the state in which the pattern division units 8 have been connected up to partway along the second layer of fence components 3.
[0060] There is no distinction between the first layer fence component 2 shown in Figure 7(d1) and the second layer fence component 3 shown in Figure 6(d2); both are the same shape. The second layer fence component 3 in Figure 7(d2) is shown as the first layer fence component 2 shown in Figure 7(d1) inverted vertically.
[0061] Next, as shown in Figure 7(e), the first layer of fence components 2 and the second layer of fence components 3 are stacked in an inverted orientation and connected by welding or the like, so that the honeycomb structure shape 22 of the first layer and the honeycomb structure shape 23 of the second layer overlap with a slight offset, in order to form the aforementioned pattern 5, thereby completing the mesh fence 1.
[0062] In this example, as shown in Figure 7(e), the upper left 41 and lower left 42 of the mesh fence 1 lack the wire material that forms one side of the cube that constitutes the pattern 5. Therefore, it is possible to add and connect the wire material that forms one side to the upper left 41 and lower left 42, or to manufacture the fence by replacing only the shape of the wire material forming the left side with the wire material that has one side in the upper left 41 (lower left 42).
[0063] In this example, the wires from one side of the cubes that make up the pattern 5 protrude from the upper right portion 43 and the lower right portion 44 of the mesh fence 1. Therefore, the upper right portion 43 and the lower right portion 44 may be cut off, or the wires forming the right side may be replaced with wires that do not have the upper right portion 43 (lower right portion 44) portion during manufacturing.
[0064] The mesh fence 1 may be manufactured by stacking the completed first layer fence component 2, which has had all of its pattern division units 8 connected, with the completed second layer fence component 3, which has also had all of its pattern division units 8 connected. Alternatively, the mesh fence 1 may be manufactured by sequentially connecting the pattern division units 8 of the second layer fence component 3 (the second layer fence component 3 before completion) so that it is stacked on top of the first layer fence component 2 (the first layer fence component 2 before completion), which is still in the process 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, extending them horizontally, by connecting the pattern division units 8 of the first layer fence component 2 to each other and then connecting the pattern division units 8 of the second layer fence component 3 on top of them.
[0065] The pattern division units 8 are connected by welding. Since the upper side of the mesh fence 1 is easily touched and visible to people, it is preferable that there are no welded areas there. For this reason, as shown in Figure 7(a1), it is preferable that the ends of the pattern division units 8 are not located within the sides of the hexagon that appears at the upper end of the fence in the vertical direction. For example, the upper end of the pattern division unit 8 shown in Figure 7(a1) and the upper end of the pattern division unit 8 shown in Figure 7(b1) are welded together at the welded joint 51 shown in Figure 7(c1), and therefore do not appear on the upper side of the mesh fence 1.
[0066] Furthermore, if the welding points (connection points) between the pattern division units 8 are to be formed on the upper side of the mesh fence 1, the shape of the pattern division unit 8 may be the shape obtained by dividing the basic pattern unit 7 shown in Figure 6(a) vertically down the middle into two. In this case, by connecting the pattern division units 8 alternately and symmetrically, the first layer of fence components 2 and the second layer of fence components 3 can be formed.
[0067] [Second Embodiment] In the first embodiment, an example was shown in which the pattern components 22 and 23 of the first and second layers forming the pattern 5 have a honeycomb structure shape made up of regular hexagons arranged in a row. However, in the second embodiment, an example of a different shape is shown.
[0068] Figure 8 shows a method for manufacturing a mesh fence 1a to which the present invention is applied. The figure shows an example of a shape in which rhombuses are arranged without gaps as the pattern components 22a and 23a of the first and second layers. Furthermore, this example shows an example in which semicircular shapes are arranged at the top and bottom of the pattern components 22a and 23a of the first and second layers.
[0069] The manufacturing method for the mesh fence 1a is as follows: First, as shown in Figures 8(a1) and 8(a2), wires 12 and 13 are bent to form pattern division units 8a. Wires 12 and 13 are identical, and there is no distinction between the pattern division units 8a shown in Figures 8(a1) and 8(a2); both have the same shape.
[0070] As shown in Figures 8(a1) and 8(b1), the pattern division unit 8a is formed such that when two are connected facing each other in a symmetrical (rotationally symmetrical) manner, it takes the shape of the pattern base unit 7a shown in Figure 8(c1). The pattern base unit 7a is the basic unit of the repeating pattern in the horizontal direction of the fence of the pattern components 22 and 23, and is a rhombic structure shape 22a in which rhombuses are arranged in a row in the vertical direction of the fence. In this example, the upper and lower parts of the pattern base unit 7a are formed in a semicircular shape. The same applies to Figures 8(a2) to 8(c2).
[0071] As shown in Figure 8(a1), the pattern division unit 8a is formed in such a shape that its end is not located on the upper side of the basic pattern unit 7a, so that no welding points (connection points) are generated at the top.
[0072] As shown in Figure 8(d1), multiple pattern division units 8a are connected alternately in a symmetrical manner to form the first layer of fence components 2a. The figure shows the state where the pattern division units 8 are connected up to partway up the first layer of fence components 2a. Similarly, as shown in Figure 8(d2), multiple pattern division units 8a are connected alternately in a symmetrical manner to form the second layer of fence components 3a. The first layer of fence components 2a shown in Figure 8(d1) and the second layer of fence components 3a shown in Figure 8(d2) have the same shape.
[0073] Next, as shown in Figure 8(e), the first layer of fence components 2a and the second layer of fence components 3a are stacked with a left-right offset and connected by welding or other means to complete the mesh fence 1a. As a result, the first layer of pattern components 22a and the second layer of pattern components 23a overlap with a left-right offset, forming a pattern 5a on the mesh fence 1a.
[0074] Alternatively, instead of using the pattern division unit 8a shown in Figures 8(a1) and 8(a2), the mesh fence 1a may be manufactured by first producing the basic pattern unit 7a shown in Figures 8(c1) and 8(c2).
[0075] The shapes of the pattern components 22 and 23 (22a and 23a) in the first and second layers are arbitrary. For example, the pattern components in the first and second layers may be a combination of arbitrary geometric shapes such as triangles, squares, and polygons. The pattern components in the first and second layers do not have to be tiling figures that completely fill a plane with a specific pattern; for example, they may be circles, ellipses, polygons, curves, bent lines, or a combination of multiple different shapes. The method of offsetting (direction and distance of offset) when the pattern components in the first and second layers are the same shape is arbitrary. The shapes of the pattern components in the first and second layers may be different. When the shapes of the pattern components in the first and second layers are different, they may be overlapped without offset or with offset, depending on the design. By overlapping the pattern components of the first and second layers, it is possible to create pictorial designs such as animals, characters, people, vehicles, landscapes, buildings, natural objects, and man-made objects as patterns.
