[0016] Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the drawings. Note that the following embodiments do not limit the invention according to each claim, and not all combinations of the features described in the embodiments are essential for the solution means of the invention.

[0017] [First Embodiment] FIG. 1 is a front view showing one form of a fence configured using a fence panel according to a first embodiment of the present invention; FIG. 2 is an exploded perspective view showing a structure for attaching the fence panel of the present invention to a support column; FIG. 3 is a front view showing the fence panel according to the first embodiment of the present invention; FIG. 4 is an enlarged view of part A in FIG. 3, which is a connecting part of the fence panel according to the first embodiment of the present invention; FIG. 5 is a cross-sectional view taken along line B-B in FIG. 3, which is a connecting part of the fence panel according to the first embodiment of the present invention; FIG. 6 is a perspective view showing the connecting part of the fence panel according to the first embodiment of the present invention. In this specification, one end and the other end in the horizontal direction, and the upper side and the lower side in the vertical direction are defined as the directions of the arrows shown in FIG. 3.

[0018] As shown in FIG. 1, the fence panel 1a according to the present embodiment constitutes a fence 100a together with a support column 2 erected perpendicular to the ground and a mounting fitting 3 for fixing the fence panel 1a to the support column 2. As shown in FIG. 1, the fence panel 1a can be used to construct a continuous fence 100a of the required length by engaging the horizontal ends of adjacent fence panels 1a with each other and connecting a plurality of them.

[0019] As shown in FIG. 1, as an example, the support column 2 is made of a round pipe-shaped steel pipe, and its lower end is buried in a foundation such as mortar and erected on the ground. Further, as shown in FIG. 2, a plurality of through holes for passing through the mounting fitting 3 are formed at intervals in the longitudinal direction in the support column 2.

[0020] As shown in FIG. 2, the mounting fitting 3 is a substantially J-shaped fitting, and a male screw portion is formed at the end of the long portion. The mounting fitting 3 fixes the fence panel 1a to the support column 2 by hooking the horizontal wire member 20 of the fence panel 1a described later and tightening the male screw portion passing through the through hole of the support column 2 with a nut.

[0021] As shown in Figure 3, the fence panel 1a is a wire mesh formed by welding together multiple vertical wires 10 and multiple horizontal wires 20, each made of iron wire with a circular cross-section, in a grid pattern. Some of the horizontal wires 20 have a first engaging portion 21 at one end that extends outward beyond the vertical wires 10 and is capable of engaging with the other end of a horizontal wire 20 of an adjacent fence panel 1a. Furthermore, the horizontal wires 20 having the first engaging portion 21 have a second engaging portion 23 at the other end that extends outward beyond the vertical wires 10 and is capable of engaging with the other end of a horizontal wire 20 of an adjacent fence panel 1a. Multiple such horizontal wires 20 having the first engaging portion 21 and the second engaging portion 23 are arranged vertically at intervals. In addition, to prevent corrosion due to rust, etc., the fence panel 1a is preferably coated with zinc plating or electrostatic powder coating using polyester resin as the base paint.

[0022] The first engaging portion 21 is formed by processing one end of the transverse wire 20. As shown in Figure 4, the first engaging portion 21 is formed to be approximately C-shaped in a front view while maintaining the wire diameter of the transverse wire 20. The inner diameter of the approximately C-shaped first engaging portion 21 is formed to be equal to or slightly larger than the wire diameter of the transverse wire 20, and the second engaging portion 23 of the adjacent fence panel 1a can engage with the approximately C-shaped inner diameter. It is preferable that the center of the approximately C-shaped inner diameter of the first engaging portion 21 is located on the axis of the transverse wire 20, so that when the fence panels 1a are connected, the heights of the transverse wires 20 of adjacent fence panels 1a match, thus maintaining straightness. In addition, a first opening 22 is formed in the approximately C-shaped first engaging portion 21 such that the distance between the end face of the iron wire and the transverse wire 20 is dimension S1.

[0023] The first opening 22 is formed such that its dimension S1 is slightly smaller than the diameter of the horizontal wire 20. By forming the dimension S1 smaller than the diameter of the horizontal wire 20 in this way, when the second engaging portion 23 of the adjacent fence panel 1a is engaged with the first engaging portion 21, the first engaging portion 21 elastically deforms to push open the first opening 22. Furthermore, after engagement with the second engaging portion 23, the first engaging portion 21 returns to its original spacing of dimension S1, making it difficult to release the engagement between the first engaging portion 21 and the second engaging portion 23.

[0024] The second engaging portion 23 is formed by processing the other end of the transverse wire 20. As shown in Figure 5, the second engaging portion 23 is formed to be approximately C-shaped in plan view while maintaining the wire diameter of the transverse wire 20. The inner diameter of the approximately C-shaped second engaging portion 23 is formed to be equal to or slightly larger than the wire diameter of the transverse wire 20, and the first engaging portion 21 of the adjacent fence panel 1a can engage with the approximately C-shaped inner diameter. It is preferable that the center of the approximately C-shaped inner diameter of the second engaging portion 23 be located on the axis of the transverse wire 20, so that when the fence panels 1a are connected, the positions of the transverse wires 20 of adjacent fence panels 1a coincide in the depth direction, thus maintaining straightness. In addition, a second opening 24 is formed in the approximately C-shaped second engaging portion 23 such that the distance between the end face of the iron wire and the transverse wire 20 is dimension S2.

[0025] The second opening 24 is formed such that its dimension S2 is slightly smaller than the diameter of the horizontal wire 20. By forming the dimension S2 smaller than the diameter of the horizontal wire 20 in this way, when the first engaging portion 21 of the adjacent fence panel 1a is engaged with the second engaging portion 23, the second engaging portion 23 elastically deforms to widen the second opening 24. Furthermore, after engagement with the first engaging portion 21, the second engaging portion 23 returns to its original spacing of dimension S2, making it difficult to disengage the engagement between the first engaging portion 21 and the second engaging portion 23.

[0026] As shown in Figure 6, the first engaging portion 21 and the second engaging portion 23 formed in this manner can be engaged with each other, allowing adjacent fence panels 1a to be connected without the use of fastening members such as fixing parts or bolts. Furthermore, by providing multiple first engaging portions 21 and second engaging portions 23 in the vertical direction, the connection between adjacent fence panels 1a can be made stronger. In addition, since the horizontal ends of the fence panels 1a are connected to and supported by adjacent fence panels 1a, as shown in Figure 1, one support post 2 can support one fence panel 1a.

[0027] The fence panel 1a according to the first embodiment described above is provided with a first engaging portion 21 at one end of the horizontal wire 20 and a second engaging portion 23 at the other end, and the case in which adjacent fence panels 1a are connected by engaging the first engaging portion 21 and the second engaging portion 23 has been described. The fence panel 1b according to the second embodiment described next is provided with a different connecting portion than the fence panel 1a according to the first embodiment. Note that parts that are the same as or similar to those of the fence panel 1a described above are denoted by the same reference numerals and their description is omitted.

[0028] [Second Embodiment]

[0029] Figure 7 is a front view showing one form of a fence constructed using a fence panel according to the second embodiment of the present invention; Figure 8 is a front view showing a fence panel according to the second embodiment of the present invention; Figure 9 is a connecting portion of the fence panel according to the second embodiment of the present invention, a cross-sectional view of CC in Figure 8; Figure 10 is a connecting portion of the fence panel according to the second embodiment of the present invention, viewed from arrow D in Figure 9; and Figure 11 is a perspective view showing a connecting portion of the fence panel according to the second embodiment of the present invention.

[0030] As shown in Figure 7, the fence panel 1b according to this embodiment constitutes a fence 100b together with a support post 2 erected vertically to the ground and a mounting bracket 3 for fixing the fence panel 1b to the support post 2. As shown in Figure 7, the horizontal end of the fence panel 1b engages with the horizontal end of an adjacent fence panel 1, and by connecting multiple panels, a continuous fence 100b of the required length can be constructed.

[0031] As shown in Figure 8, the fence panel 1b consists of multiple vertical wire members 1 made of iron wire with a circular cross-section. 0 and This is a wire mesh formed by welding multiple horizontal wires 20 in a grid pattern. Some of the horizontal wires 20 have an engagement portion 2 at the other end that extends outward beyond the vertical wires 10 and can engage with the vertical wires 10 of the adjacent fence panel 1. 5 Multiple horizontal wires 20 having such engaging portions 25 are arranged at intervals in the vertical direction. Furthermore, to prevent corrosion due to rust, etc., the fence panel 1b is preferably coated with zinc plating or electrostatic powder coating using polyester resin as the base paint.

[0032] The engaging portion 25 is formed by processing the other end of the horizontal wire 20. As shown in Figure 9, the engaging portion 25 is formed to be approximately C-shaped in plan view while maintaining the wire diameter of the horizontal wire 20. The engaging portion 25 is formed so that the inner diameter of the approximately C-shape is equal to or slightly larger than the wire diameter of the vertical wire 10, and the vertical wire 10 of adjacent fence panels 1b can engage with the approximately C-shaped inner diameter. It is preferable that the center of the approximately C-shaped inner diameter of the engaging portion 25 is formed at the same position in the depth direction as the center of the wire diameter of the vertical wire 10 in plan view, because when adjacent fence panels 1b are connected, the positions of the horizontal wires 20 of adjacent fence panels 1b coincide in the depth direction, thus maintaining straightness. Furthermore, as shown in Figure 10, if the engaging portion 25 is formed to be shifted downward by the distance of the wire diameter of the horizontal wire 20 when viewed from the front, it is preferable that when adjacent fence panels 1 are connected, the heights of the horizontal wires 20 of adjacent fence panels 1b will match, thus maintaining straightness. Also, if the engaging portion 25 is formed to be shifted downward by the distance of the wire diameter of the horizontal wire 20 when viewed from the front, the engaging portion 25 will support the lower surface of the horizontal wire 20 of adjacent fence panels 1, and it is preferable that the fence panel 1, whose lower surface of the horizontal wire 20 is supported, does not move downward due to vibration or the like. It has been explained that the engaging portion 25 is formed to be shifted downward by the distance of the wire diameter of the horizontal wire 20 when viewed from the front, but the shape of the engaging portion 25 is not limited to this, and it may also be formed to be shifted upward by the distance of the wire diameter of the horizontal wire 20 when viewed from the front. In such cases, the horizontal wires 20 of adjacent fence panels 1 support the lower surface of the engaging portion 25, which is preferable as it prevents the fence panel 1 supported by the lower surface of the engaging portion 25 from moving downward due to vibration or the like. Furthermore, multiple engaging portions 25 that are shifted upward by the distance of the wire diameter of the horizontal wire 20 and engaging portions 25 that are shifted downward may be combined and arranged at the other end of the fence panel 1b. In addition, an opening 26 is formed in the substantially C-shaped engaging portion 25 such that the distance between the end face of the iron wire and the horizontal wire 20 is dimension S3.

[0033] The opening 26 is formed such that its dimension S3 is slightly smaller than the diameter of the vertical wire 10. By forming the dimension S3 smaller than the diameter of the vertical wire 10 in this way, when engaging the vertical wire 10 of an adjacent fence panel 1b with the engaging portion 25, the engaging portion 25 elastically deforms to widen the opening 26. Furthermore, after the engaging portion 25 and the vertical wire 10 are engaged, the opening 26 returns to its original spacing of dimension S3, making it difficult to release the engagement between the engaging portion 25 and the vertical wire 10.

[0034] By engaging the engaging portion 25 formed in this manner with the vertical wire 10 as shown in Figure 11, adjacent fence panels 1b can be connected without using fastening members such as fixing parts or bolts. Furthermore, by providing multiple engaging portions 25 in the vertical direction, the connection between adjacent fence panels 1b can be made stronger.

[0035] In this embodiment, the support column 2 was described as a round steel pipe, but it is not limited to this; it may also be a pipe with a polygonal cross-section, or made of a metal such as stainless steel alloy or aluminum alloy. Furthermore, while the method of erecting the support column 2 was described as being embedded in a foundation such as mortar, it is not limited to this; it may also be erected by known methods such as directly driving the support column 2 into the soil or by installing a base plate on a concrete surface. Also, while the method of attaching the fence panels 1a and 1b to the support column 2 was described as using a roughly J-shaped mounting bracket 3, it is not limited to this method; it may also be fixed by known methods such as using a strip-shaped retaining plate or other fitting to press the fence panel 1 against the support column 2. It is clear from the claims that such modified or improved forms may also fall within the technical scope of the present invention. [Explanation of Symbols]
