The upper wire comprises a first upper component wire with one end connected to the upper end of the first vertical wire, a second upper component wire with one end connected to the upper end of the second vertical wire, and an upper bridge wire spanning between the other ends of the first upper component wire and the second upper component wire. The lower wire comprises a first lower component wire with one end connected to the lower end of the first vertical wire, a second lower component wire with one end connected to the lower end of the second vertical wire, and a lower bridge wire spanning between the other ends of the first lower component wire and the second lower component wire. The upper bridge wire comprises the first upper component wire and the The first upper component wire and the second upper component wire are connected in such a way that the second upper component wire has a step-like shape with a height difference equal to the thickness of the first upper component wire, and the lower bridge wire is formed in such a way that the first lower component wire and the second lower component wire have a step-like shape with a height difference equal to the thickness of the first lower component wire, and the plurality of pattern basic units are arranged in the left-right direction of the fence such that at least a portion of the first upper component wire of the pattern basic unit and the second upper component wire of the adjacent pattern basic unit overlap. It is characterized by being present.
[0008] Claim 2 The fence described in the claim 1 The present invention is characterized in that the first upper component wire, the second upper component wire, the first lower component wire, and the second lower component wire are all formed to be the same length.
[0010] Claim 3 The fence described in claim 1 or 2 The present invention relates to the invention described above, characterized in that the first longitudinal wire is formed in an arc shape, and the second longitudinal wire is formed in a shape symmetrical to the first longitudinal wire. The fence according to claim 4 is a fence having a plurality of first vertical wires and a plurality of second vertical wires, and having a plurality of pattern basic units, the pattern basic unit having a pair of first vertical wires and 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, the plurality of pattern basic units are arranged in the left-right direction of the fence such that a portion of the upper wire of the pattern basic unit and a portion of the upper wire of an adjacent pattern basic unit overlap, the first vertical wires are formed in an arc shape, and the second vertical wires are formed in a left-right symmetrical shape with respect to the first vertical wires. The fence described in claim 5 is the same as that described in claim 4, characterized in that the upper wire is formed in a straight line and the lower wire is formed in a straight line.

[Effects of the Invention]
[0015] The fence and method for manufacturing the fence of the present invention are arranged in the left-right direction of the fence, with the first and second vertical wires overlapping. This makes it easy to bend the wires and increase the density of the wires, thus enabling the creation of complex designs with excellent aesthetic appeal. Furthermore, by arranging the pattern basic units in the left-right direction of the fence, the fence can be manufactured simply.
[0016] Furthermore, when the upper and lower wires of the basic pattern unit are formed in a stepped shape and arranged in the left-right direction of the fence so that at least a portion of the first upper structural wire and the second upper structural wire of the adjacent basic pattern unit overlap, it is possible to create a complex design with excellent aesthetic appeal while having a fence thickness equivalent to two wires (two layers).
[0017] Furthermore, when the first upper structural wire, the second upper structural wire, the first lower structural wire, and the second lower structural wire are all formed to the same length, the basic pattern units are arranged to overlap evenly in the left-right direction on both the upper and lower edges of the fence. This improves the appearance and increases the strength by allowing for longer overlapping lengths.
[0018] When the upper wire is formed in a straight line and the lower wire is formed in a straight line, the shape of the basic pattern unit becomes simple, so the basic pattern unit can be manufactured simply and quickly.
[0019] Also, when 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 about the left and right, if it is a fence with a design in which a plurality of circular or elliptical annular wires are arranged overlapping in the left-right direction, there will be a large number of layers (multiple wires) overlapping at the upper and lower parts of the fence, resulting in congestion and making manufacturing difficult. However, by providing the upper wire and the lower wire as in the present invention, the overlap of the wires can be reduced, so a fence with a design excellent in design property including an arcuate configuration of a symmetrical shape that looks close to a circle or an ellipse can be manufactured simply.
[0020] Also, when the basic pattern unit is formed by bending a single wire, it can be manufactured more simply and quickly than when a plurality of wires are connected to form it.
[0021] Also, when unnecessary parts are cut off from both sides of the fence manufacturing member manufactured in the arrangement process of the basic pattern unit, the fence can be manufactured simply and quickly.
[0022] Also, when side members that will become the side parts of the fence are connected to both sides of the fence manufacturing member manufactured in the arrangement process of the basic pattern unit, the fence can be manufactured simply without waste of wires.

[0024] The following describes in detail embodiments for carrying out the present invention, but the scope of the present invention is not limited to these embodiments.
[0025] [First Embodiment] Figure 1 shows a front view of fence 1, Figure 2 shows a cross-sectional view of fence 1 along line BB in Figure 1, Figure 3 shows a plan view (top view) (a), a front view (b), and a bottom view (bottom view) (c) of pattern basic unit 5, Figure 4 shows a partially enlarged plan view (a) and partially enlarged bottom view (c) of the pattern basic unit, which are enlargements of the part indicated by the dashed circle frame in Figure 3, Figure 5 shows an explanatory diagram of the structure and manufacturing method of fence 1, and Figures 6 and 7 show the manufacturing method of fence 1. In this specification, terms indicating directions such as up, down, right, left, vertical, and horizontal are expressed based on the direction when viewed facing the front (fence surface) of fence 1 (the direction when represented in a six-view drawing), as shown in Figure 1. The configuration of fence 1 to which the present invention is applied is described below. 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 pattern basic unit 5 having 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, and the plurality of pattern basic units 5 are arranged in the left-right direction of the fence such that a portion of the upper wire 8 of one pattern basic unit 5 and a portion of the upper wire 8 of an adjacent pattern basic unit 5 overlap. Furthermore, the fence 1 to which the present invention is applied has an upper wire 8 which has a first upper structural wire 11 with one end connected to the upper end of the first vertical wire 6, a second upper structural wire 12 with one end connected to the upper end of the second vertical wire 7, and an upper bridge wire 13 which spans the other ends of the first upper structural wire 11 and the second upper structural wire 12, and a lower wire 9 which has a first lower structural wire 21 with one end connected to the lower end of the first vertical wire 6, a second lower structural wire 22 with one end connected to the lower end of the second vertical wire 7, and a lower bridge wire 23 which spans the other ends of the first lower structural wire 21 and the second lower structural wire 22, and the upper bridge wire 13 is the first upper structural wire The first upper structural wire 11 and the second upper structural wire 12 are formed in a shape that connects them such that the first upper structural wire 11 and the second upper structural wire 12 have a step-like shape with a step difference equal to the thickness of the first upper structural wire 11, and the lower bridge wire 23 is formed in a shape that connects the first lower structural wire 21 and the second lower structural wire 22 such that the first lower structural wire 21 and the second lower structural wire 22 have a step difference equal to the thickness of the first lower structural wire 21, and it is preferable that multiple pattern basic units 5 are arranged in the left-right direction of the fence such that at least a portion of the first upper structural wire 11 of the pattern basic unit 5 and the second upper structural wire 12 of the 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 structural wire 11, the second upper structural wire 12, the first lower structural wire 21, and the second lower structural wire 22 are all formed to be the same length. Furthermore, it is preferable that the fence 1 to which the present invention is applied has a first vertical wire 6 formed in an arc shape, and a second vertical wire 7 formed in a shape symmetrical to the first vertical wire 6. The following provides a detailed explanation.
[0026] As shown in Figures 1 and 2, the fence 1, for example, has a rectangular shape and has a plurality of first vertical wires 6 and a plurality of second vertical wires 7. The first vertical wires 6 are formed to extend from the bottom to the top of the fence. The second vertical wires 7 are formed to extend 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 located on the front side of the fence 1 (the foreground side in Figure 1). The plurality of second vertical wires 7 are located on the back side of the fence 1 (the background side in Figure 1). Therefore, the fence 1 is formed as a two-layer structure in which a first fence-forming layer 2 having a plurality of first vertical wires 6 and a second fence-forming layer 3 having a plurality of second vertical wires 7 are laminated together.
[0027] As shown in the figure, multiple first vertical wires 6 and multiple second vertical wires 7 overlap to form a complex design with excellent aesthetic appeal.
[0028] In this example, the first longitudinal wire 6 is shown as being formed in an arc shape, which is either a circular arc or an elliptical arc. Furthermore, in this example, the second longitudinal wire 7 is shown as being formed in an arc shape, which is either a circular arc or an elliptical arc. Additionally, in this example, the second longitudinal wire 7 is shown as being formed in a shape symmetrical to the first longitudinal wire 6. As shown in Figure 1, the first longitudinal wire 6 is formed in the shape of the right-hand arc portion of a circle or ellipse, and the second longitudinal wire 7 is formed in the shape of the left-hand arc portion of a circle or ellipse.
[0029] As shown in Figure 1, the fence 1 may be provided with reinforcing and protective side frame members 31 made of reinforcing bars or the like on the right and left sides as needed. Also, as shown in Figures 1 and 2, the fence 1 may be provided with reinforcing horizontal bars 33, 36 and horizontal bars 34, 35 for fixing the support posts, as needed. These are fixed to the fence 1 by welding or the like.
[0030] Fence 1 has multiple basic pattern units 5 arranged on it. Figure 3 shows the basic pattern unit 5. Figure 3(a) is a plan view of the basic pattern unit 5, Figure 3(b) is a front view of the basic pattern unit 5, and Figure 3(c) is a bottom view of the basic pattern unit 5.
[0031] The basic pattern unit 5 is formed entirely of wires of the same thickness (same cross-sectional shape), such as reinforcing bars, and is formed in a ring shape with a first longitudinal wire 6, a second longitudinal wire 7, an upper wire 8, and a lower wire 9. The first longitudinal wire 6 is the right-hand portion with a length shorter than half the circumference of the circle or ellipse that forms the basis of the shape, and is formed in a vertically symmetrical shape as an example. The second longitudinal wire 7 is the left-hand portion with a length shorter than half the circumference of the circle or ellipse that forms the basis of the shape, and is formed in a vertically symmetrical shape as an example.
[0032] The upper wire 8 spans the upper ends of a pair of first vertical wires 6 and second vertical wires 7. The upper wire 8 constitutes part of the upper part (top edge) of the fence 1. The lower wire 9 spans the lower ends of a pair of first vertical wires 6 and second vertical wires 7. The lower wire 9 constitutes part of the lower part (bottom edge) of the fence 1.
[0033] In this example, since the first vertical wire 6 and the second vertical wire 7 are vertically symmetrical, as shown in Figure 3(b), 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 directly below the upper wire 8.
[0034] The basic pattern unit 5 is preferably formed by bending a single wire. As an example, Figure 3(b) shows the start end 41 and end end 42 of a single wire that forms the basic pattern unit 5. The start end 41 and end end 42 of the wire are preferably placed in the middle of the lower wire 9 so as not to be conspicuous. The start end 41 and end end 42 of the wire are preferably fixed to each other by welding or the like.
[0035] Figure 4(a) shows an enlarged view (partially an enlarged plan view) of the area indicated by the dashed circle in Figure 3(a). Figure 4(c) shows an enlarged view (partially an enlarged bottom view) of the area indicated by the dashed circle in Figure 3(c).
[0036] As shown in Figure 4(a), the upper wire 8 comprises a first upper structural wire 11, a second upper structural wire 12, and an upper transponder wire 13. The first upper structural wire 11 is formed in a straight line. One end of the first upper structural wire 11 is connected to the upper end of the first vertical wire 6. The second upper structural wire 12 is formed in a straight line. One end of the second upper structural wire 12 is connected to the upper end of the second vertical wire 7. One end of the upper transponder wire 13 is connected to the other end of the first upper structural wire 11, and the other end of the upper transponder wire 13 is connected to the other end of the second upper structural wire 12. The first upper structural wire 11 and the second upper structural wire 12 are formed to the same length. The upper transponder 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 structural wire 11 and the second upper structural wire 12 in a staircase (Z) shape. The upper transponder wire 13 is shaped such that the difference in height (step height) formed by the first upper structural wire 11 and the second upper structural wire 12 is equal to the thickness of the first upper structural wire 11 (second upper structural wire 12). In other words, the upper transponder wire 13 is formed in a shape that connects the first upper structural wire 11 and the second upper structural wire 12 in a staircase (Z) shape (a parallel offset shape) with a step difference equal to the thickness of the first upper structural wire 11 (second upper structural wire 12). In other words, as shown in Figure 5(a), when multiple upper wires 81, 82...87 are arranged in the left-right direction of the fence such that the first upper structural wire 11 of the upper wire 8 and the second upper structural wire 12 of the adjacent upper wire 8 overlap (are in contact), the upper wires 8 are formed in such a way that the first upper structural wires 111, 112...117 are aligned in a straight line, and the second upper structural wires 121, 122...127 are also aligned in a straight line. Therefore, the thickness of the fence 1 can be made thin, equivalent to the thickness of two wires.
[0037] As shown in Figure 4(c), the lower wire 9 has a first lower structural wire 21, a second lower structural wire 22, and a lower bridge wire 23. The first lower structural wire 21 is formed in a straight line. One end of the first lower structural wire 21 is connected to the lower end of the first vertical wire 6. The second lower structural wire 22 is formed in a straight line. One end of the second lower structural wire 22 is connected to the lower end of the second vertical wire 7. One end of the lower bridge wire 23 is connected to the other end of the first lower structural wire 21, and the other end of the lower bridge wire 23 is connected to the other end of the second lower structural wire 22. The first lower structural wire 21 and the second lower structural wire 22 are formed to the same length. The lower bridge 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 structural wire 21 and the second lower structural wire 22 in a staircase (Z) shape. The lower bridge wire 23 is shaped such that the difference in height (step height) formed by the first lower structural wire 21 and the second lower structural wire 22 is equal to the thickness of the first lower structural wire 21 (second lower structural wire 22). In other words, the lower bridge wire 23 is formed in a shape that connects the first lower structural wire 21 and the second lower structural wire 22 in a staircase (Z) shape (a parallel offset shape) with a step difference equal to the thickness of the first lower structural wire 21 (second lower structural wire 22). In other words, as shown in Figure 5(c), when multiple lower wires 91, 92...97 are arranged horizontally such that the first lower component wire 21 of the lower wire 9 and the second lower component wire 22 of the adjacent lower wire 9 overlap (are in contact), the lower wires 9 are formed in such a way that the first lower component wires 211, 212...217 are aligned in a straight line, and the second lower component wires 221, 222...227 are also aligned in a straight line. Therefore, the thickness of the fence 1 can be reduced to the thickness of two wires.
[0038] In this example, the upper wire 8 shown in Figure 4(a) and the lower wire 9 shown in Figure 4(c) are formed to be the same shape. That is, the first upper component wire 11 and the first lower component wire 21 are the same shape, the second upper component wire 12 and the second lower component wire 22 are the same shape, and the upper bridge wire 13 and the lower bridge wire 23 are the same shape. Furthermore, the four wires, the first upper component wire 11, the second upper component wire 12, the first lower component wire 21, and the second lower component wire 22, are all formed to be the same length.
[0039] Figure 5 shows an explanatory diagram of the structure and manufacturing method of fence 1. Figure 5(a) is a plan view, Figure 5(b) is a front view, and Figure 5(c) is a bottom view.
[0040] Multiple basic pattern units 5 are manufactured, and as shown in Figure 5, the main part of the fence 1 is formed by arranging these multiple basic pattern units 5 so that a portion of the upper wire 8 (lower wire 9) overlaps in the left-right direction of the fence. The figure shows the state during the manufacturing process and illustrates an example in which seven basic pattern units 51 to 57 are 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 such that the first upper structural wire 111 of the pattern basic unit 51 and the second upper structural wire 122 of the adjacent pattern basic unit 52 overlap at least partially. The same applies to other pattern basic units 5, where a pattern basic unit 5 and an adjacent pattern basic unit 5 are arranged and fixed such that the first upper structural wire 11 of the pattern basic unit 5 and the second upper structural wire 12 of the adjacent pattern basic unit 5 overlap at least partially. The figures show seven pattern basic units 51 to 57, and similarly, the main part of the fence 1 is formed by arranging multiple pattern basic units 5, 5...5 with some overlap in the left-right direction of the fence. The method for manufacturing a fence to which the present invention applies includes a pattern basic unit arrangement step of arranging and fixing the pattern basic units 5 in this manner.
[0042] The overlapping length between the first upper structural wire 11 and the adjacent second upper structural wire 12 can be any predetermined length. In other words, the distance between one pattern basic unit 5 and the adjacent pattern basic unit 5 can be any predetermined distance. When the lengths of the first upper structural wire 11 and the second upper structural wire 12 are the same, the overlapping length can be increased, which is preferable because it increases the strength. When the first upper structural wire 11 and the adjacent second upper structural wire 12 overlap completely, it is preferable because it maximizes the strength.
[0043] Furthermore, as shown in Figures 5(b) and 5(c), the pattern basic unit 51 (lower wire 91) and the adjacent pattern basic unit 52 (lower wire 92) are arranged and fixed such that the first lower structural wire 211 of the pattern basic unit 51 and the second lower structural wire 222 of the adjacent pattern basic unit 52 overlap at least partially. The same applies to the other pattern basic units 5, where the pattern basic unit 5 and the adjacent pattern basic unit 5 are arranged and fixed such that the first lower structural wire 21 of the pattern basic unit 5 and the second lower structural wire 22 of the adjacent pattern basic unit 5 overlap at least partially.
[0044] The overlapping length between the first lower structural wire 21 and the adjacent second lower structural wire 22 can be any predetermined length. When the lengths of the first lower structural wire 21 and the second lower structural wire 22 are the same, the overlapping length can be increased, which is preferable because it increases the strength. When the first lower structural wire 21 and the adjacent second lower structural wire 22 overlap completely, it is preferable because it 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 to overlap in the same way as the upper wire 8.
[0045] The basic pattern units 5 are fixed together by welding or other means at any point where they overlap in parallel or intersect.
[0046] As shown in Figure 6, multiple basic pattern 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 parts 51 and 52 are cut off from both sides of this fence manufacturing member 61 (cutting process) to complete the fence 1 with a rectangular outer shape. By manufacturing in this way, the fence 1 can be manufactured simply and quickly. If necessary, side frame members 31 may be attached to the right and left sides of the fence 1 by welding or other means.
[0047] The shape of the unnecessary parts 51 and 52 to be removed is arbitrary. Alternatively, the fence manufacturing component 61 with parts 51 and 52 left intact may be used as the fence 1.
[0048] Alternatively, as shown in Figure 7, multiple basic pattern units 5 are connected in the left-right direction of the fence to form a fence manufacturing member 62 that is approximately the same width (horizontal width) as the fence 1 in the left-right direction. Side members that will become the sides of the fence are attached to both sides of this fence manufacturing 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 manufacturing member 62 by welding, etc., and a side member 56 for forming the left side of the fence 1 is attached to the left side by welding, etc. (side attachment process), completing a fence 1 with a rectangular outer shape. The shapes of the side members 55 and 56 attached to the sides of the fence manufacturing member 62 are arbitrary. The wires that make up the side members 55 and 56 may also be attached to the fence manufacturing member 62 one by one by welding, etc. By manufacturing in this way, the fence 1 can be manufactured simply and without waste of wires. Side frame members 31 may be provided on the side members 55 and 56 as needed. Alternatively, the fence manufacturing component 62 may be used as the fence 1 without attaching the side members 55 and 56.
[0049] Figure 8 shows a cross-sectional view of the BB line of a modified example of fence 1 (corresponding to the BB line in Figure 1). As shown in the figure, the upper and / or lower sides of 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 basic pattern unit 5 can be formed by bending them in a "V" shape. Although not shown, the upper and / or lower sides of fence 1 may also be formed in an arc shape. In this way, the side shape (BB line cross-sectional shape) of fence 1 may be formed in any shape.
[0050] The first vertical wire 6 and the second vertical wire 7 of the basic pattern unit 5 may be colored with the same color, or they may be colored with different colors.
[0051] [Second Embodiment] In the first embodiment, an example of a fence 1 using a stepped upper wire 8 and lower wire 9 was described. In the second embodiment, an example of a fence 1a using a straight upper wire 8a and a straight lower wire 9a will be described. In the following, components similar to those already described will be denoted by the same reference numerals, and detailed explanations will be omitted.
[0052] Figure 9 shows the pattern basic unit 5a to be placed on fence 1a. Figure 9(a) is a plan view of the pattern basic unit 5a, Figure 9(b) is a front view of the pattern basic unit 5a, and Figure 9(c) is a bottom view of the pattern basic unit 5a.
[0053] The basic pattern unit 5a is formed entirely of wires such as reinforcing bars, and is formed in 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 those in the basic pattern unit 5 of fence 1.
[0054] The upper wire 8a is straight and spans the upper ends of a pair of first vertical wires 6 and second vertical wires 7. The lower wire 9 is straight and spans the lower ends of a pair of first vertical wires 6 and second vertical wires 7.
[0055] The basic pattern unit 5a is preferably formed by bending a single wire. As an example, Figure 9(b) shows the start end 41 and end end 42 of a single wire that forms the basic pattern unit 5.
[0056] Figure 10 shows an explanatory diagram of the structure and manufacturing method of fence 1a. Figure 10(a) is a plan view, Figure 10(b) is a front view, and Figure 10(c) is a bottom view.
[0057] Multiple basic pattern units 5a are manufactured, and as shown in Figure 10, the main part of the fence 1 is formed by arranging these multiple basic pattern units 5a in the left-right direction of the fence such that a portion of the upper wire 8a (lower wire 9a) overlaps. The figure shows the state during the manufacturing process and illustrates an example in which seven basic pattern units 5a1 to 5a7 are arranged.
[0058] As shown in Figures 10(a) and 10(b), pattern basic unit 5a1 (upper wire 8a1) and the adjacent pattern basic unit 5a2 (upper wire 8a2) are arranged and fixed so that they partially overlap. The same applies to the other pattern basic units 5a, where pattern basic unit 5a and the adjacent pattern basic unit 5a are arranged and fixed so that the upper wire 8a of pattern basic unit 5a and the upper wire 8a of the adjacent pattern basic unit 5a partially overlap. The figures show seven pattern basic units 5a1 to 5a7, and similarly, the main part of the fence 1a is formed by arranging multiple pattern basic units 5a, 5a...5a partially overlapping in the left-right direction of the fence. The method for manufacturing a fence to which the present invention applies includes a pattern basic unit arrangement step in which the pattern basic units 5a are arranged and fixed in this manner.
[0059] Furthermore, as shown in Figures 10(b) and 10(c), the pattern basic unit 5a1 (lower wire 9a1) and the adjacent pattern basic unit 5a2 (lower wire 9a2) are arranged and fixed so that they partially overlap. The same applies to the other pattern basic units 5a, where the pattern basic unit 5a and the adjacent pattern basic unit 5a are arranged and fixed so that the lower wire 9a and the adjacent lower wire 9a partially overlap.
[0060] The overlapping length between the upper wire 8a and an adjacent upper wire 8a can be any predetermined length. The overlapping length between the lower wire 9a and an adjacent lower wire 9a can also be any predetermined length. It is preferable that the lengths of the upper wire 8a and the lower wire 9a are the same. In this example, since the upper wire 8a and the lower wire 9a have the same shape, the lower wire 9 is arranged to overlap in the same way as the upper wire 8.
[0061] As shown in Figure 10(b), if the overlapping length between an upper wire 8a and an adjacent upper wire 8a is less than or equal to half the length of the upper wire 8a, and the overlapping length between a lower wire 9a and an adjacent lower wire 9a is less than or equal to half the length of the lower wire 9a, then the overlap of the pattern basic unit 5a (upper wire 8a, lower wire 9a) at the same location is equivalent to two wires, meaning that the stacking of the pattern basic unit 5a at the same location is two layers, which is preferable because it prevents the fence 1a from becoming too thick. If the overlapping length between an upper wire 8a (lower wire 9a) and an adjacent upper wire 8a (lower wire 9a) exceeds half the length of the upper wire 8a (lower wire 9a), then the overlap of the pattern basic unit 5a (upper wire 8a, lower wire 9a) at the same location is equivalent to three or more wires, meaning that the stacking of the pattern basic unit 5a at the same location is three or more layers.
[0062] The basic pattern units 5a are fixed together by welding or other means at any point where they overlap in parallel or intersect.
[0063] The plan view, front view, and bottom view of fence 1a are shown in much the same way as the respective figures of fence 1 in Figure 1, so their illustration is omitted. Furthermore, similar to fence 1, the sides of fence 1a can be cut off or attached in the manner shown in Figure 6 or Figure 7 to form a rectangular or other shape.
[0064] [Third Embodiment] As a third embodiment, an example of a fence 1b having a first vertical wire 6b and a second vertical wire 7b having different shapes from those of the first embodiment is 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 shape and has a plurality of first vertical wires 6b and a plurality of second vertical wires 7b.
[0066] The first vertical wires 6b are formed to extend from the bottom to the top of the fence. The second vertical wires 7b are formed to extend from the bottom to the top of the fence. Multiple first vertical wires 6b are arranged at equal intervals in the left-right direction of the fence (left-right direction in the figure). Multiple second vertical wires 7b are arranged at equal intervals in the left-right direction of the fence. Multiple first vertical wires 6b are located on the front side of the fence 1b (the front side in the figure). Multiple second vertical wires 7b are located on the back side of the fence 1b (the back side in the figure). Therefore, the fence 1b is formed as a two-layer structure in which a first fence component layer 2b having multiple first vertical wires 6b and a second fence component layer 3b having multiple second vertical wires 7b are stacked.
[0067] As shown in the figure, multiple first vertical wires 6b and multiple second vertical wires 7b overlap to form a complex design with excellent aesthetic appeal.
[0068] Fence 1b has multiple basic pattern units 5b arranged on it. Figure 12 shows the basic pattern unit 5b. Figure 12(a) is a plan view of the basic pattern unit 5b, Figure 12(b) is a front view of the basic pattern unit 5b, and Figure 12(c) is a bottom view of the basic pattern unit 5b.
[0069] The basic pattern unit 5b is formed entirely of wires such as reinforcing bars, and is annular in shape with a first longitudinal wire 6b, a second longitudinal wire 7b, an upper wire 8, and a lower wire 9. The upper wire 8 and lower wire 9 are formed in the same shape as those of the fence 1 in Embodiment 1.
[0070] The first vertical wire 6b is an example of a curved shape that is asymmetrical vertically. The second vertical wire 7b is asymmetrical vertically and is an example of a shape that combines a bent line and a curve. The first vertical wire 6b and the second vertical wire 7b are asymmetrical horizontally.
[0071] By arranging multiple basic pattern units 5b in a horizontal direction, as described earlier for fence 1, the fence 1b shown in Figure 11 can be manufactured.
[0072] Furthermore, the upper wire 8 and lower wire 9 of pattern basic unit 5b may be used in place of the upper wire 8a and lower wire 9a of fence 1a, which have already been described.
[0073] As described in the first to third embodiments above, by forming the shapes of the first longitudinal wires 6, 6b and the second longitudinal wires 7, 7b into various arbitrary shapes, a complex design with excellent aesthetic appeal can be formed. For example, the shapes of the first longitudinal wires 6, 6b and the second longitudinal wires 7, 7b can be any straight line, bent line, or curved line, or a combination of at least two of these.
[0074] The shapes of the upper wire 8 and lower wire 9 shown in Figure 4 may be different. In short, any shape that allows the basic pattern units 5, 5...5 (5b, 5b...5b) to be connected in the left-right direction is acceptable.
[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, such that at least a portion of the first upper structural wire 11 of the pattern basic unit 5 and the second upper structural wire 12 of the adjacent pattern basic unit 5 overlap. For example, the lengths of the first upper structural wire 11 and the second upper structural wire 12 may be different.
[0076] Furthermore, the shape of the lower wire 9 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, such that at least a portion of the first lower structural wire 21 of the pattern basic unit 5 and the second lower structural wire 22 of the adjacent pattern basic unit 5 overlap. For example, the lengths of the first lower structural wire 21 and the second lower structural wire 22 may be different.
[0077] Furthermore, although Figure 9 shows an example where the upper wire 8a and lower wire 9a are straight, the upper wire 8a and lower wire 9a may also be curved. [Explanation of Symbols]
