[0004] In order to enhance the design of a fence, it is necessary to bend the wire that makes up the fence surface or increase the density of the wire, which makes it difficult to create complex designs.

[0005] The present invention has been made to solve the above-mentioned problems, and aims to provide a fence that can be easily manufactured and that can be provided with a complex design with excellent aesthetic appeal. [Means for solving the problem]

[0006] The fence described in claim 1 of the claims, which has been made to achieve the above-mentioned object, is a fence having a plurality of first vertical wires and a plurality of second vertical wires, and has a plurality of pattern basic units, each of which has a pair of the first vertical wires and the second vertical wires, an upper wire spanning the upper ends of the pair of first and second vertical wires, and a lower wire spanning the lower ends of the pair of first and second vertical wires, and the plurality of pattern basic units are arranged in the left-right direction of the fence so that a portion of the upper wire of one pattern basic unit overlaps with a portion of the upper wire of an adjacent pattern basic unit.

[0007] The fence described in claim 2 is the fence described in claim 1, and the upper wire comprises a first upper constituent wire having one end connected to the upper end of the first vertical wire, a second upper constituent wire having one end connected to the upper end of the second vertical wire, and an upper bridge wire that is bridged between the other ends of the first upper constituent wire and the second upper constituent wire, and the lower wire comprises a first lower constituent wire having one end connected to the lower end of the first vertical wire, a second lower constituent wire having one end connected to the lower end of the second vertical wire, and a lower bridge wire that is bridged between the other ends of the first lower constituent wire and the second lower constituent wire, and the upper bridge wire is bridged between the first upper constituent wire and the second lower constituent wire. The first upper component wire and the second upper component wire are formed in a shape that connects them so that the first upper component wire and the second upper component wire form a stepped shape with a step difference equal to the thickness of the first upper component wire, and the lower connecting wire is formed in a shape that connects the first lower component wire and the second lower component wire so that the first lower component wire and the second lower component wire form a stepped shape with a step difference equal to the thickness of the first lower component wire, and the multiple pattern basic units are arranged in the left-right direction of the fence so that at least a portion of the first upper component wire of one pattern basic unit overlaps with the second upper component wire of an adjacent pattern basic unit.

[0008] The fence described in claim 3 is the fence described in claim 2, characterized in that the first upper constituent wire, the second upper constituent wire, the first lower constituent wire, and the second lower constituent wire are all formed to the same length.

[0009] The fence described in claim 4 is the fence described in claim 1, characterized in that the upper wire is formed in a straight line and the lower wire is also formed in a straight line.

[0010] The fence described in claim 5 is the fence described in any one of claims 1 to 4, characterized in that the first vertical wire is formed in an arc shape, and the second vertical wire is formed in a shape symmetrical to the first vertical wire.

[0011] The method for manufacturing a fence described in claim 6 is a method for manufacturing a fence having a plurality of first vertical wires and a plurality of second vertical wires, and is characterized in that it manufactures a plurality of pattern basic units, each of which has a pair of the first vertical wires and the second vertical wires, an upper wire spanning the upper ends of the pair of first and second vertical wires, and a lower wire spanning the lower ends thereof, and includes a pattern basic unit arranging step of arranging and fixing the plurality of pattern basic units in the left-right direction of the fence so that a portion of the upper wire of one pattern basic unit overlaps with a portion of the upper wire of an adjacent pattern basic unit.

[Effects of the Invention]

[0015] In the fence and fence manufacturing method of the present invention, multiple pattern base units are arranged in the left-right direction of the fence, and the first vertical wires and second vertical wires are arranged so as to overlap, making it easy to bend the wires and increase the density of the wires, thereby enabling the creation of complex designs with excellent aesthetic appeal.Furthermore, by arranging the pattern base units side by side in the left-right direction of the fence, the fence can be manufactured easily.

[0016] Furthermore, if the upper and lower wire members of the pattern basic unit are formed into a stepped shape and arranged in the left-right direction of the fence so that at least a portion of the first upper component wire member overlaps with the second upper component wire member of the adjacent pattern basic unit, it is possible to create a fence that is two wire members (two layers) thick while still creating a complex design with excellent aesthetic appeal.

[0017] Furthermore, if the first upper constituent wire, the second upper constituent wire, the first lower constituent wire and the second lower constituent wire are all formed to the same length, the pattern basic units are arranged side by side, overlapping evenly in the left-right direction on both the upper and lower edges of the fence, which improves the appearance and increases the strength because the overlapping length can be increased.

[0018] When the upper wire is formed in a straight line shape and the lower wire is formed in a straight line shape, the shape of the pattern basic unit is simple, so that the pattern basic unit can be manufactured easily and quickly.

[0019] Furthermore, if the first vertical wire is formed in an arc shape and the second vertical wire is formed in a shape symmetrical to the first vertical wire, when a fence is designed with multiple circular or elliptical ring-shaped wires stacked on top of each other in the left-right direction, the wires will overlap in many layers (many pieces) at the top and bottom of the fence, making it difficult to manufacture.However, by providing upper and lower wires as in the present invention, the overlapping of the wires can be reduced, making it possible to easily manufacture a fence with an excellent design that includes a symmetrical arc-shaped configuration that looks close to a circle or ellipse.

[0020] Furthermore, when the basic pattern unit is formed by bending one wire, it can be manufactured more easily and quickly than when it is formed by connecting a plurality of wires.

[0021] Furthermore, when unnecessary portions are cut off from both sides of the fence manufacturing members manufactured in the step of arranging the pattern basic units, the fence can be manufactured simply and quickly.

[0022] Furthermore, when connecting side members that will become the fence sides to both sides of the fence manufacturing members manufactured in the process of arranging the pattern basic units, the fence can be manufactured easily without wasting wire material.

[0025] [First embodiment] Fig. 1 shows a front view of fence 1, Fig. 2 shows a cross-section of fence 1 taken along line BB in Fig. 1, Fig. 3 shows a plan view (top view) (a), a front view (b), and a bottom view (bottom view) (c) of a pattern basic unit 5, Fig. 4 shows a partially enlarged plan view (a) and a partially enlarged bottom view (c) of the pattern basic unit, which are enlarged views of the area enclosed by the dashed circle in Fig. 3, Fig. 5 shows an explanatory diagram of the structure and manufacturing method of fence 1, and Figs. 6 and 7 show a manufacturing method for fence 1. Note that in this specification, terms indicating directions such as up, down, right, left, vertical, and horizontal are expressed based on the directions when viewed from the front (fence surface) of fence 1 (directions when represented in a six-sided view), as shown in Fig. 1. The structure of a fence 1 to which the present invention is applied will be described. The fence 1 to which the present invention is applied has a plurality of first vertical wires 6 and a plurality of second vertical wires 7, and has a plurality of pattern basic units 5, each of which has a pair of first vertical wires 6 and second vertical wires 7, an upper wire 8 spanning the upper ends of the pair of first and second vertical wires, and a lower wire 9 spanning the lower ends thereof, and the plurality of pattern basic units 5 are arranged in the left-right direction of the fence so that a portion of the upper wire 8 of one pattern basic unit 5 overlaps with a portion of the upper wire 8 of an adjacent pattern basic unit 5. In addition, in the fence 1 to which the present invention is applied, the upper wire 8 has a first upper constituent wire 11 having one end connected to the upper end of the first vertical wire 6, a second upper constituent wire 12 having one end connected to the upper end of the second vertical wire 7, and an upper bridge wire 13 that is strung across the other ends of the first upper constituent wire 11 and the second upper constituent wire 12, and the lower wire 9 has a first lower constituent wire 21 having one end connected to the lower end of the first vertical wire 6, a second lower constituent wire 22 having one end connected to the lower end of the second vertical wire 7, and a lower bridge wire 23 that is strung across the other ends of the first lower constituent wire 21 and the second lower constituent wire 22, and the upper bridge wire 13 is strung across the first upper constituent wire The first upper component wire 11 and the second upper component wire 12 are formed in a shape that connects them so that they form a stepped shape with a step difference equal to the thickness of the first upper component wire 11, and the lower laying wire 23 is formed in a shape that connects the first lower component wire 21 and the second lower component wire 22 so that they form a stepped shape with a step difference equal to the thickness of the first lower component wire 21, and it is preferable that the multiple pattern basic units 5 are arranged in the left-right direction of the fence so that at least a portion of the first upper component wire 11 of a pattern basic unit 5 and the second upper component wire 12 of an adjacent pattern basic unit 5 overlap. Furthermore, in the fence 1 to which the present invention is applied, it is preferable that the first upper constituent wire 11, the second upper constituent wire 12, the first lower constituent wire 21 and the second lower constituent wire 22 are all formed to the same length. In addition, in the fence 1 to which the present invention is applied, it is preferable that the first vertical wire 6 is formed in an arc shape and the second vertical wire 7 is formed in a shape symmetrical to the first vertical wire 6. The specific details will be explained below.

[0026] As shown in Figures 1 and 2, the fence 1 has, for example, a rectangular outer shape and includes a plurality of first vertical wires 6 and a plurality of second vertical wires 7. The first vertical wires 6 are formed to a length that reaches from the bottom to the top of the fence. The second vertical wires 7 are formed to a length that reaches from the bottom to the top of the fence. The plurality of first vertical wires 6 are arranged at equal intervals in the left-right direction of the fence (left-right direction in Figure 1). The plurality of second vertical wires 7 are arranged at equal intervals in the left-right direction of the fence (left-right direction in Figure 1). The plurality of first vertical wires 6 are arranged on the front side of the fence 1 (the near side in Figure 1). The plurality of second vertical wires 7 are arranged on the back side of the fence 1 (the far side in Figure 1). For this reason, the fence 1 is formed in a two-layer structure in which a first fence component layer 2 having a plurality of first vertical wires 6 and a second fence component layer 3 having a plurality of second vertical wires 7 are stacked.

[0027] As shown in the figure, a plurality of first vertical wires 6 and a plurality of second vertical wires 7 are overlapped to form a complex design with excellent aesthetic appeal.

[0028] In this example, the first vertical wire 6 is formed in an arc shape that is a circular arc or an elliptical arc. Also, in this example, the second vertical wire 7 is formed in an arc shape that is a circular arc or an elliptical arc. Furthermore, in this example, the second vertical wire 7 is formed in a bilaterally symmetrical shape to the first vertical wire 6. As shown in FIG. 1, the first vertical wire 6 is formed in the shape of an arc portion on the right side of a circle or an ellipse, and the second vertical wire 7 is formed in the shape of an arc portion on the left side of a circle or an ellipse.

[0029] As shown in Fig. 1, the fence 1 may have side frame members 31 made of reinforcing bars or the like on the right and left sides, as needed. Also, as shown in Figs. 1 and 2, the fence 1 may have reinforcing horizontal bars 33 and 36 made of reinforcing bars or the like, and horizontal bars 34 and 35 for fixing the posts, as needed. These are fixed to the fence 1 by welding or the like.

[0030] A plurality of pattern basic units 5 are arranged on the fence 1. 3 shows the pattern basic unit 5. FIG. 3(a) is a plan view of the pattern basic unit 5, FIG. 3(b) is a front view of the pattern basic unit 5, and FIG. 3(c) is a bottom view of the pattern basic unit 5.

[0031] For example, the pattern basic unit 5 is entirely formed of wire rods of the same thickness (same cross-sectional shape) such as rebar, and is formed into a ring shape with a first vertical wire rod 6, a second vertical wire rod 7, an upper wire rod 8, and a lower wire rod 9. The first vertical wire rod 6 is located on the right side of the circle or ellipse on which the shape is based, and is shorter than half the circumference of the circle or ellipse, and is formed, for example, in a vertically symmetrical shape. The second vertical wire rod 7 is located on the left side of the circle or ellipse on which the shape is based, and is shorter than half the circumference of the circle or ellipse, and is formed, for example, in a vertically symmetrical shape.

[0032] The upper wire 8 is suspended between the upper ends of the pair of first vertical wires 6 and second vertical wires 7. The upper wire 8 forms part of the upper part (upper edge) of the fence 1. The lower wire 9 is suspended between the lower ends of the pair of first vertical wires 6 and second vertical wires 7. The lower wire 9 forms part of the lower part (lower edge) of the fence 1.

[0033] In this example, the first vertical wire 6 and the second vertical wire 7 are vertically symmetrical, so that the upper wire 8 and the lower wire 9 have the same length on the left and right, and the lower wire 9 is located just below the upper wire 8, as shown in Figure 3(b).

[0034] The pattern basic unit 5 is preferably formed by bending a single wire. As an example, FIG. 3(b) shows a start end 41 and a finish end 42 of one wire that forms the pattern basic unit 5. The start end 41 and the finish end 42 of the wire are preferably located midway along the lower wire 9 so as not to be noticeable. The start end 41 and the finish end 42 of the wire are preferably fixed to each other by welding or the like.

[0035] An enlarged view (partially enlarged plan view) of the area enclosed by the dashed circle in Figure 3(a) is shown in Figure 4(a), and an enlarged view (partially enlarged bottom view) of the area enclosed by the dashed circle in Figure 3(c) is shown in Figure 4(c).

[0036] As shown in FIG. 4(a), the upper wire 8 has a first upper component wire 11, a second upper component wire 12, and an upper connecting wire 13. The first upper component wire 11 is formed in a straight line. One end of the first upper component wire 11 is connected to the upper end of the first vertical wire 6. The second upper component wire 12 is formed in a straight line. One end of the second upper component wire 12 is connected to the upper end of the second vertical wire 7. One end of the upper connecting wire 13 is connected to the other end of the first upper component wire 11, and the other end of the upper connecting wire 13 is connected to the other end of the second upper component wire 12. The first upper component wire 11 and the second upper component wire 12 are formed to have the same length. The upper connecting wire 13 is formed in a shape (for example, a curved shape, a staircase (Z-shape), or a straight shape) that connects the first upper connecting wire 11 and the second upper connecting wire 12 so that they form a staircase (Z-shape). The upper connecting wire 13 is shaped so that the step (step height) formed by the first upper connecting wire 11 and the second upper connecting wire 12 is equal to the thickness of the first upper connecting wire 11 (second upper connecting wire 12). In other words, the upper connecting wire 13 is formed in a shape that connects the first upper connecting wire 11 and the second upper connecting wire 12 so that they form a staircase (Z-shape) (a shape offset in parallel) with a step equal to the thickness of the first upper connecting wire 11 (second upper connecting wire 12). 5(a), when a plurality of upper wires 81, 82...87 are arranged in the left-right direction of the fence so that a first upper constituent wire 11 of an upper wire 8 overlaps (contacts) a second upper constituent wire 12 of an adjacent upper wire 8, the first upper constituent wires 111, 112...117 are aligned in a straight line and the second upper constituent wires 121, 122...127 are aligned in a straight line. This allows the thickness of the fence 1 to be reduced to the thickness of two wires.

[0037] As shown in FIG. 4(c), the lower wire 9 has a first lower component wire 21, a second lower component wire 22, and a lower interconnecting wire 23. The first lower component wire 21 is formed in a straight line. One end of the first lower component wire 21 is connected to the lower end of the first vertical wire 6. The second lower component wire 22 is formed in a straight line. One end of the second lower component wire 22 is connected to the lower end of the second vertical wire 7. One end of the lower interconnecting wire 23 is connected to the other end of the first lower component wire 21, and the other end of the lower interconnecting wire 23 is connected to the other end of the second lower component wire 22. The first lower component wire 21 and the second lower component wire 22 are formed to have the same length. The lower connecting wire 23 is formed in a shape (for example, a curved shape, a staircase (Z-shape), or a straight shape) that connects the first lower component wire 21 and the second lower component wire 22 so that they form a staircase (Z-shape). The lower connecting wire 23 is shaped so that the step (step height) formed by the first lower component wire 21 and the second lower component wire 22 is equal to the thickness of the first lower component wire 21 (second lower component wire 22). In other words, the lower connecting wire 23 is formed in a shape that connects the first lower component wire 21 and the second lower component wire 22 so that they form a staircase (Z-shape) (a shape offset in parallel) with a step equal to the thickness of the first lower component wire 21 (second lower component wire 22). 5(c), when the plurality of lower wires 91, 92...97 are arranged in the left-right direction so that the first lower structural wire 21 of one lower wire 9 overlaps (contacts) the second lower structural wire 22 of the adjacent lower wire 9, the first lower structural wires 211, 212...217 are aligned in a straight line and the second lower structural wires 221, 222...227 are aligned in a straight line. This allows the thickness of the fence 1 to be reduced to the thickness of two wires.

[0038] In this example, the upper wire 8 shown in Fig. 4(a) and the lower wire 9 shown in Fig. 4(c) are formed to have the same shape. That is, the first upper constituent wire 11 and the first lower constituent wire 21 have the same shape, the second upper constituent wire 12 and the second lower constituent wire 22 have the same shape, and the upper interconnecting wire 13 and the lower interconnecting wire 23 have the same shape. Furthermore, the first upper constituent wire 11, the second upper constituent wire 12, the first lower constituent wire 21, and the second lower constituent wire 22 are all formed to have the same length.

[0039] 5A and 5B are explanatory diagrams of the structure and manufacturing method of the fence 1. Fig. 5(a) is a plan view, Fig. 5(b) is a front view, and Fig. 5(c) is a bottom view.

[0040] A plurality of pattern basic units 5 are manufactured and then arranged in the left-right direction of the fence so that the upper wires 8 (lower wires 9) partially overlap, as shown in Figure 5, to form the main part of the fence 1. This figure shows a state during manufacturing, and shows an example in which seven pattern basic units 51 to 57 have been arranged.

[0041] As shown in Figures 5(a) and 5(b), a pattern basic unit 51 (upper wire 81) and an adjacent pattern basic unit 52 (upper wire 82) are arranged and fixed so that the first upper constituent wire 111 of the pattern basic unit 51 and the second upper constituent wire 122 of the adjacent pattern basic unit 52 at least partially overlap. The same applies to the other pattern basic units 5, and the pattern basic unit 5 and the adjacent pattern basic unit 5 are arranged and fixed so that the first upper constituent wire 11 of the pattern basic unit 5 and the second upper constituent wire 12 of the adjacent pattern basic unit 5 at least partially overlap. Seven pattern basic units 51 to 57 are shown in the figure, but the main part of the fence 1 is similarly formed by arranging multiple pattern basic units 5, 5...5 in a partially overlapping manner in the left-right direction of the fence. A method for manufacturing a fence to which the present invention is applied includes a pattern basic unit arranging process in which the pattern basic units 5 are arranged and fixed in this manner.

[0042] The overlap length between the first upper constituent wire 11 and the adjacent second upper constituent wire 12 may be any predetermined length. In other words, the distance between the pattern basic unit 5 and the adjacent pattern basic unit 5 may be any predetermined distance. If the first upper constituent wire 11 and the second upper constituent wire 12 have the same length, the overlap length can be made longer, which is preferable, as this increases the strength. If the first upper constituent wire 11 and the adjacent second upper constituent wire 12 overlap entirely, this increases the strength, which is preferable.

[0043] 5(b) and 5(c), a pattern basic unit 51 (lower wire 91) and an adjacent pattern basic unit 52 (lower wire 92) are arranged and fixed so that the first lower constituent wire 211 of the pattern basic unit 51 and the second lower constituent wire 222 of the adjacent pattern basic unit 52 at least partially overlap. The same applies to the other pattern basic units 5, and the pattern basic unit 5 and the adjacent pattern basic unit 5 are arranged and fixed so that the first lower constituent wire 21 of the pattern basic unit 5 and the second lower constituent wire 22 of the adjacent pattern basic unit 5 at least partially overlap.

[0044] The overlap length between the first lower component wire 21 and the adjacent second lower component wire 22 may be any predetermined length. If the first lower component wire 21 and the second lower component wire 22 are the same length, the overlap length can be increased, which is preferable, as this increases the strength. If the first lower component wire 21 and the adjacent second lower component wire 22 overlap entirely, this is preferable, as this maximizes the strength. In this example, since the upper wire 8 and the lower wire 9 have the same shape, the lower wire 9 is arranged overlapping in the same manner as the upper wire 8.

[0045] The pattern basic units 5 are fixed together by welding or the like at any parallel overlapping locations or any intersecting locations.

[0046] As shown in Figure 6, a plurality of pattern basic units 5 are connected in the left-right direction of the fence to form a fence manufacturing member 61 that is larger than the left-right width (horizontal width) of the fence 1. Unnecessary portions 51 and 52 are removed from both sides of this fence manufacturing member 61 (removal process), completing the fence 1 with a rectangular outline. By manufacturing in this manner, the fence 1 can be manufactured easily and quickly. If necessary, side frame members 31 may be attached to the right and left sides of the fence 1 by welding or the like.

[0047] The shapes of the unnecessary portions 51 and 52 to be cut off are arbitrary. It is also possible to use the fence manufacturing member 61 as the fence 1 without cutting out the portions 51 and 52, leaving them as they are.

[0048] Alternatively, as shown in FIG. 7 , multiple pattern base units 5 are connected in the left-right direction to form a fence construction member 62 having a width (horizontal width) approximately equal to the width of the fence 1. Side members that will form the fence sides are attached to both sides of this fence construction member 62. Specifically, a side member 55 for forming the right side of the fence 1 is attached to the right side of the fence construction member 62 by welding or the like, and a side member 56 for forming the left side of the fence 1 is attached to the left side by welding or the like (side attachment process), completing the fence 1 with a rectangular outline. The side members 55, 56 attached to the sides of the fence construction member 62 can have any shape. The wires that make up the side members 55, 56 may be attached one by one to the fence construction member 62 by welding or the like. This manufacturing process allows for easy and efficient construction of the fence 1 without waste of wire. Side frame members 31 may be attached to the side members 55, 56 as needed. The fence manufacturing member 62 may be used as the fence 1 without attaching the side members 55 and 56.

[0049] FIG. 8 shows a cross-sectional view of a modified example of the fence 1 taken along line BB (a view corresponding to line BB in FIG. 1). As shown in the figure, the side surfaces of the upper and / or lower parts of the fence 1 may be formed into a shape that is bent, for example, into a "L" shape. In this case, the upper and lower parts of the pattern basic unit 5 may be formed by bending them into a "L" shape. Furthermore, although not shown, the side surfaces of the upper and / or lower parts of the fence 1 may be formed into a shape that is bent into an arc. In this way, the side surface shape (cross-sectional shape taken along line BB) of the fence 1 may be formed into any shape.

[0050] The first vertical wire 6 and the second vertical wire 7 of the pattern basic unit 5 may be colored the same color or different colors.

[0051] [Second embodiment] In the first embodiment, an example of a fence 1 using stepped upper wires 8 and lower wires 9 was described, but in the second embodiment, an example of a fence 1a using straight upper wires 8a and straight lower wires 9a will be described. Note that, in the following, components similar to those already described will be assigned the same reference numerals and detailed description will be omitted.

[0052] Fig. 9 shows a pattern basic unit 5a arranged on the fence 1a. Fig. 9(a) is a plan view of the pattern basic unit 5a, Fig. 9(b) is a front view of the pattern basic unit 5a, and Fig. 9(c) is a bottom view of the pattern basic unit 5a.

[0053] The pattern basic unit 5a is formed entirely from wires such as rebar, and is formed into a ring shape with a first vertical wire 6, a second vertical wire 7, an upper wire 8a, and a lower wire 9a. The first vertical wire 6 and the second vertical wire 7 are the same as the pattern basic unit 5 of the fence 1.

[0054] The upper wire 8a is linear and spans the upper ends of the pair of first and second vertical wires 6 and 7. The lower wire 9 is linear and spans the lower ends of the pair of first and second vertical wires 6 and 7.

[0055] The pattern basic unit 5a is preferably formed by bending a single wire. As an example, a start end 41 and a finish end 42 of a single wire forming the pattern basic unit 5 are shown in FIG.

[0056] An explanatory diagram of the structure and manufacturing method of the fence 1a is shown in Figure 10. Figure 10(a) is a plan view, Figure 10(b) is a front view, and Figure 10(c) is a bottom view.

[0057] A plurality of pattern basic units 5a are manufactured and then arranged in the left-right direction of the fence so that the upper wires 8a (lower wires 9a) partially overlap, as shown in Figure 10, to form the main part of the fence 1. This figure shows a state during manufacturing, and shows an example in which seven pattern basic units 5a1 to 5a7 have been arranged.

[0058] As shown in Figures 10(a) and 10(b), a pattern basic unit 5a1 (upper wire 8a1) and an adjacent pattern basic unit 5a2 (upper wire 8a2) are arranged and fixed so that they partially overlap. The other pattern basic units 5a are similarly arranged and fixed so that the upper wire 8a of the pattern basic unit 5a and the upper wire 8a of the adjacent pattern basic unit 5a partially overlap. Seven pattern basic units 5a1 to 5a7 are shown in the figures, but the main part of the fence 1a is similarly formed by arranging multiple pattern basic units 5a, 5a... 5a, so that they partially overlap in the left-right direction of the fence. A method for manufacturing a fence to which the present invention is applied includes a pattern basic unit arranging process in which pattern basic units 5a are lined up and fixed in this manner.

[0059] 10(b) and 10(c), a pattern basic unit 5a1 (lower wire 9a1) and an adjacent pattern basic unit 5a2 (lower wire 9a2) are arranged and fixed so as to partially overlap each other. The same applies to the other pattern basic units 5a, and the pattern basic unit 5a and the adjacent pattern basic unit 5a are arranged and fixed so as to partially overlap each other with the lower wire 9a and the adjacent lower wire 9a.

[0060] The overlap length between the upper wire 8a and the adjacent upper wire 8a may be any predetermined length. The overlap length between the lower wire 9a and the adjacent lower wire 9a may be any predetermined length. It is preferable that the upper wire 8a and the lower wire 9a have the same length. In this example, since the upper wire 8a and the lower wire 9a have the same shape, the lower wire 9a is arranged overlapping in the same way as the upper wire 8a.

[0061] 10(b), if the overlap length between the upper wire 8a and the adjacent upper wire 8a is less than half the length of the upper wire 8a and the overlap length between the lower wire 9a and the adjacent lower wire 9a is less than half the length of the lower wire 9a, the overlap length between the pattern basic units 5a (upper wire 8a, lower wire 9a) at the same location is two wires, i.e., two layers of pattern basic units 5a are stacked at the same location, which is preferable because the fence 1a does not become too thick.If the overlap length between the upper wire 8a (lower wire 9a) and the adjacent upper wire 8a (lower wire 9a) exceeds half the length of the upper wire 8a (lower wire 9a), the overlap length between the pattern basic units 5a (upper wire 8a, lower wire 9a) at the same location is three or more wires, i.e., three or more layers of pattern basic units 5a are stacked at the same location.

[0062] The pattern basic units 5a are fixed together by welding or the like at any parallel overlapping locations or any intersecting locations.

[0063] The plan view, front view, and bottom view of the fence 1a are omitted because they are almost the same as the views of the fence 1 shown in Figure 1. Also, just like the fence 1, the sides of the fence 1a can be cut off or attached in the same way as in Figure 6 or Figure 7, and the outer shape can be formed into a square or the like.

[0064] [Third embodiment] As the third embodiment, an example of a fence 1b having first vertical wires 6b and second vertical wires 7b with shapes different from those of the first embodiment will be shown.

[0065] Figure 11 shows a front view of a fence 1b to which the present invention is applied. The fence 1b has a rectangular outer shape and includes a plurality of first vertical wires 6b and a plurality of second vertical wires 7b.

[0066] The first vertical wire 6b is formed with a length that reaches from the bottom to the top of the fence. The second vertical wire 7b is formed with a length that reaches from the bottom to the top of the fence. The multiple first vertical wires 6b are arranged at equal intervals in the left-right direction of the fence (left-right direction in the figure). The multiple second vertical wires 7b are arranged at equal intervals in the left-right direction of the fence. The multiple first vertical wires 6b are arranged on the front side of the fence 1b (the front side of the figure). The multiple second vertical wires 7b are arranged on the back side of the fence 1b (the back side of the figure). Therefore, the fence 1b has a two-layer structure in which a first fence constituent layer 2b having a multiple first vertical wires 6b and a second fence constituent layer 3b having a multiple second vertical wires 7b are laminated.

[0067] As shown in the figure, a plurality of first vertical wires 6b and a plurality of second vertical wires 7b are overlapped to form a complex design with excellent aesthetic appeal.

[0068] A plurality of pattern basic units 5b are arranged on the fence 1b. The pattern basic unit 5b is shown in Fig. 12. Fig. 12(a) is a plan view of the pattern basic unit 5b, Fig. 12(b) is a front view of the pattern basic unit 5b, and Fig. 12(c) is a bottom view of the pattern basic unit 5b.

[0069] The entire pattern basic unit 5b is formed from wire rods such as rebar, and is formed into a ring shape having a first vertical wire rod 6b, a second vertical wire rod 7b, an upper wire rod 8, and a lower wire rod 9. The upper wire rod 8 and the lower wire rod 9 are formed into the same shapes as those of the fence 1 of the first embodiment.

[0070] The first vertical wire 6b is an example of a curved shape that is asymmetrical from top to bottom. The second vertical wire 7b is an example of a shape that is asymmetrical from top to bottom and combines bent lines and curves. The first vertical wire 6b and the second vertical wire 7b are asymmetrical from left to right.

[0071] By arranging a plurality of pattern basic units 5b side by side in the left-right direction like the fence 1 already described, a fence 1b shown in FIG. 11 can be manufactured.

[0072] The upper wire 8 and lower wire 9 of the pattern basic unit 5b may be used in place of the upper wire 8a and lower wire 9a of the fence 1a already described.

[0073] As described in the first to third embodiments, the first vertical wires 6, 6b and the second vertical wires 7, 7b can be formed into various shapes to form complex designs with excellent designability. For example, the first vertical wires 6, 6b and the second vertical wires 7, 7b can be formed into any shape of a straight line, a bent line, or a curve, or a shape that combines at least two of these shapes.

[0074] The shapes of the upper wire 8 and the lower wire 9 shown in Fig. 4 may be different. In short, it is sufficient that the pattern basic units 5, 5...5 (5b, 5b...5b) have a shape that allows them to be connected in the left-right direction.

[0075] The shape of the upper wire 8 is arbitrary as long as it allows the pattern basic units 5, 5 to be arranged side by side in the left-right direction of the fence so that at least a portion of the first upper constituent wire 11 of a pattern basic unit 5 overlaps with the second upper constituent wire 12 of an adjacent pattern basic unit 5. For example, the lengths of the first upper constituent wire 11 and the second upper constituent wire 12 may be different.

[0076] The shape of the lower wire 9 may be any shape that allows the pattern basic units 5, 5 to be arranged side by side in the left-right direction of the fence so that at least a portion of the first lower constituent wire 21 of a pattern basic unit 5 overlaps with the second lower constituent wire 22 of an adjacent pattern basic unit 5. For example, the lengths of the first lower constituent wire 21 and the second lower constituent wire 22 may be different.

[0077] Although FIG. 9 shows an example in which the upper wire 8a and the lower wire 9a are linear, the upper wire 8a and the lower wire 9a may be curved. [Explanation of symbols]
