Description

この発明は、線材を菱形に編み込んで作られた菱形金網を柵に使用したフェンスであって、侵入者がフェンスを破ったり、フェンスの上を乗り越えて侵入することを防ぎ、また、猫や犬、ネズミ、イタチ、モグラなどの小動物がフェンスの下を潜って侵入することをも防ぐ、侵入防止用フェンスの技術分野に属する。   The present invention relates to a fence using a diamond-shaped wire netting made of a wire rod woven into a diamond shape, which prevents an intruder from breaking the fence or climbing over the fence and invading a cat or a dog. , Rodents, weasels, moles and other small animals are also part of the technical field of intrusion prevention fences, which also prevent them from entering under the fence.

他人が敷地内に無断で立ち入ることを防止する侵入防止用フェンスは、現在、多種多様な構造形式のものが広く設置され実用に供されている。通例は図５、図６に例示したように、いわゆる菱形金網１を柵に使用し、その上辺部及び下辺部に骨線５を通し、左右の支柱２、２間に支持された胴縁３へ一定のピッチで複数取り付けた支持金具４により前記の骨線５を引張り状態に支持させた構成の実施例が多い。胴縁３には通例丸パイプが使用されるが、アングルを使用した実施例も多い。図７と図８は、丸パイプによる胴縁３と支持金具４及び骨線５による菱形金網１の支持構造の詳細を示している。図示した従来技術の場合は、多数の支持金具４…を使用すると共に、ボルト６とナット７を締結して骨線５を支持させる作業が必要であり、手間とコストが多くかかるという問題点がある。   At present, intrusion prevention fences for preventing others from entering the premises without permission are widely installed and put to practical use. Usually, as illustrated in FIGS. 5 and 6, a so-called rhombic wire mesh 1 is used for the fence, a bone line 5 is passed through the upper side and the lower side thereof, and the trunk 3 supported between the left and right columns 2, 2. In many embodiments, the bone line 5 is supported in a tensioned state by a plurality of support fittings 4 attached at a constant pitch. A round pipe is usually used for the rim 3, but there are many embodiments using an angle. FIGS. 7 and 8 show details of a support structure of the rhombus wire mesh 1 by the body edge 3 and the support fitting 4 and the bone line 5 by the round pipe. In the case of the prior art shown in the drawing, it is necessary to use a large number of support fittings 4 and work to fasten the bolts 6 and the nuts 7 to support the bone line 5, resulting in a problem that much labor and cost are required. is there.

次に、下記の特許文献１に開示されたフェンスは、やはり柵に菱形金網を使用したものであるが、菱形金網の上辺部に、線材を捻って先端を二股形状に開いた、いわゆるツイストナックルが形成され、その直下の菱形網目に、同網目を側面方向に見て認められる網厚（図４Ｂ中の符号Ｓを参照）を利用してフラットバー形状の胴縁を通し支持させた構成である。したがって、上記の支持金具４が無用となり、ボルト６、ナット７を締結して骨線５を支持させる作業も無用の構成である。下記の特許文献２には、菱形金網の上辺部、下辺部に前記ツイストナックルを形成したものが開示されている。
特許文献３に開示された侵入防止用フェンスは、ツイストナックルが形成され、その直下の菱形網目に、やはり側面方向に見て認められる網厚（図４ＢのＳ寸法を参照）を利用して骨線を通し菱形金網が支持された構成である。
特許文献４には、やはり菱形金網が柵に使用され、フェンスの上部が外側へ弓形に傾斜した、いわゆる忍び返しを備えたセキュリティフェンスが開示されている。 Next, the fence disclosed in Patent Document 1 below also uses a diamond-shaped wire mesh for the fence, but a so-called twist knuckle in which a wire is twisted at the upper side of the diamond-shaped wire mesh to open the tip into a forked shape. Is formed, and a flat bar-shaped body edge is supported by using a net thickness (refer to a symbol S in FIG. 4B) that is observed when the net is viewed in the side direction on the rhombic net immediately below the net. is there. Therefore, the above-mentioned support bracket 4 is unnecessary, and the operation of fastening the bolt 6 and the nut 7 to support the bone line 5 is also unnecessary. Patent Document 2 below discloses a diamond-shaped wire mesh in which the twist knuckles are formed on the upper side and the lower side.
Antiintrusion fence disclosed in Patent Document 3 is twisted knuckles formed, rhombic network th immediately below, also by utilizing the AmiAtsu observed when viewed laterally (see S dimension in FIG. 4B) The configuration is such that a diamond-shaped wire mesh is supported through the bone line.
Patent Document 4 discloses a security fence provided with a so-called sneak-back, in which a diamond-shaped wire mesh is also used for a fence, and an upper part of the fence is inclined outward in an arc shape.

上記特許文献１に開示されたフェンスは、図５、図７に例示した従来技術の支持金具４が無用であり、ボルトとナットを締結して骨線を支持させる作業も無用なボルトレスの構成であり、胴縁を菱形金網上辺の網目に通すだけで支持できるから、施工性にも優れる。しかもツイストナックルの存在が、侵入者が乗り越える際の手掛かりの場を制限し、侵入防止の効果を高めることも認められる。
しかし、胴縁に使用可能なフラットバーの断面の大きさは、前記網厚の制限を受けるため、せいぜい幅寸が５ｍｍ、縦寸が２０ｍｍ程度に小さく、構造的に弱いものに限定されてしまう。従って、人の侵入防止用の構造材としては甚だ頼りなく物足りないので安心はできない。例えば手軽な金属切断機で切ったり曲げたりすることが容易である。その結果、無断の侵入者がフェンスを破って侵入することを許し易く、或いは侵入後に前記破った箇所を修復して元の形状に戻すことも容易で、侵入の痕跡を隠し易いので、侵入の早期発見にはあまり役に立たないという問題がある。まして、特許文献３に開示された侵入防止用フェンスのように、胴縁の代わりに骨線を使用した構成のものは論外である。 The fence disclosed in Patent Literature 1 does not require the support metal 4 of the related art illustrated in FIGS. 5 and 7, and has a boltless configuration in which the operation of fastening a bolt and a nut to support a bone line is unnecessary. Yes, it can be supported simply by passing the waist edge through the mesh on the upper side of the diamond-shaped wire mesh, so it is also excellent in workability. Moreover, it is recognized that the presence of the twist knuckle limits the place of clues when an intruder gets over, and enhances the effect of preventing intrusion.
However, the size of the cross section of the flat bar that can be used for the waist edge is limited to the width of 5 mm and the vertical size is as small as about 20 mm at most, because of the limitation of the mesh thickness, and is limited to a structurally weak one. . Therefore, it cannot be relied on as a structural material for preventing intrusion of human beings, because it is extremely unreliable and unsatisfactory. For example, it is easy to cut or bend with a simple metal cutting machine. As a result, it is easy to permit an unauthorized intruder to break through the fence, or to repair the broken part after intrusion and return it to its original shape. There is a problem that it is not very useful for early detection. Furthermore, a configuration using a bone line instead of the trunk as in the intrusion prevention fence disclosed in Patent Document 3 is out of the question.

したがって、本発明の目的は、図５、図７に例示した従来技術の支持金具が無用で、しかも施工性の良いボルトレスの構成であり、その上、人の侵入防止用の構造材として安心と信頼感がある強度、剛性を備え、切断したり曲げたりすることが困難な丸パイプ又は角パイプ等の胴縁を使用でき、侵入者が乗り越えたり破ったりして侵入することが至難であり、仮にもフェンスの一部を破って侵入した場合には元通りに修復することが難しく、侵入の痕跡を残し易く、侵入の早期発見に役立つ、侵入防止用フェンスを提供することである。
本発明の次の目的は、菱形金網の上辺部に人の侵入防止に効果的なツイストナックルを備え、また、下辺部にも猫や犬、ネズミ、イタチ、モグラなどの小動物がフェンスの下を潜って侵入することを防ぐツイストナックルを備えて侵入防止効果が大きく、しかも外観形状がシンプルでスマートな意匠を呈する、侵入防止用フェンスを提供することである。 Therefore, an object of the present invention is to provide a boltless configuration that does not require the conventional support fittings illustrated in FIGS. 5 and 7 and that has good workability. It has a strong sense of reliability and rigidity, and it is possible to use a rim such as a round pipe or a square pipe that is difficult to cut or bend, making it extremely difficult for intruders to climb over or break and enter. An object of the present invention is to provide an intrusion prevention fence which is difficult to repair if it breaks a part of the fence and intrudes, easily leaves traces of intrusion, and is useful for early detection of intrusion.
The next object of the present invention is to provide a twist knuckle on the upper side of the diamond-shaped wire mesh which is effective for preventing intrusion of humans, and also a small animal such as a cat, a dog, a rat, a weasel, a mole on the lower side. An object of the present invention is to provide a fence for preventing intrusion, which has a twist knuckle for preventing intrusion and has a large effect of preventing intrusion, and has a simple appearance and a smart design.

A squeeze 16 to which a plurality of barbed wires 17 are attached in a horizontal direction is formed at a portion above the support column 12 and above the upper side of the rhombic wire mesh 11.

本発明に係る侵入防止用フェンスは、菱形金網１１の上辺部に、線材を捻って先端を二股形状に開いたツイストナックル１４が形成され、該ツイストナックル１４の直下位置の左右の菱形網目と分離された菱形網目１１ａがそれぞれ当該菱形金網１１の網面に対して直角な向きに捻られており、前記直角な向きの菱形網目１１ａに胴縁１３が通されているから、胴縁１３を通す網目の加工を簡単、容易に行うことができる。しかも既往技術の支持金具類は一切無用で、施工性の良いボルトレスの構成であるから、フェンスの設置工事が容易で短工期となる。その上、フェンスの外観形状はシンプルでスマートな意匠を呈する。 In the intrusion prevention fence according to the present invention, a twist knuckle 14 whose tip is opened in a bifurcated shape by twisting a wire is formed on the upper side of the rhombus wire mesh 11, and is separated from the left and right rhombic meshes immediately below the twist knuckle 14. been rhombic mesh 11a have been twisted perpendicular orientation relative to each mesh surface of the diamond-shaped wire mesh 11, since the furring strip 13 is passed through before Kijika angle orientation of the rhombic mesh 11a, furring strips 13 The processing of the mesh that passes through can be performed easily and easily. In addition, since there is no need to use any of the support metal fittings of the existing technology and the bolt-less configuration with good workability, installation work of the fence is easy and the construction period is short. In addition, the appearance of the fence has a simple and smart design.

本発明で使用する胴縁１３の断面形状及びその大きさは、上記直角な向きの菱形網目１１ａの内法寸法を前提に、そこに内接する大きさを限度として選択でき、鋼製の丸パイプ１３Ａ、或いは角パイプ１３Ｂなどを使用できるから、人の侵入防止用の構造材として安心で充分信頼できる強度、剛性を備えたフェンスを構築して設置できる。即ち、丸パイプ１３Ａや角パイプ１３Ｂは手軽な金属切断機で切ったり曲げたりすることは困難であるから、侵入防止用フェンスとしての構造的安定性と安心感と信頼性、安全性が得られる。
そして、丸パイプ１３Ａや角パイプ１３Ｂは切ったり曲げたりすることが困難であることの反動として、仮に侵入を試みる者が胴縁１３を通した菱形網目１１ａを切断すると、ツイストナックル１４を切り飛ばしてしまうことになり、侵入後に修復しようとしてもツイストナックル１４が存在しない形態となり、元通りにはならないから、侵入の痕跡を一目瞭然に残すことになり、侵入事件の早期発見に役立つ効果を奏する。 The cross-sectional shape and the size of the body edge 13 used in the present invention can be selected based on the inner dimension of the rhombic mesh 11a in the above-mentioned perpendicular direction, as long as the size inscribed therein is limited, and a steel round pipe can be selected. 13A or a square pipe 13B can be used, so that a fence having sufficient strength and rigidity can be constructed and installed as a structural material for preventing human intrusion with reliability and sufficient reliability. That is, since it is difficult to cut or bend the round pipe 13A or the square pipe 13B with a simple metal cutter, structural stability, security, reliability and safety as an intrusion prevention fence can be obtained. .
And, as a reaction to the fact that it is difficult to cut or bend the round pipe 13A and the square pipe 13B, if a person attempting to penetrate cuts the rhombic mesh 11a through the torso 13, the twist knuckle 14 is cut off. Thus, even if an attempt is made to repair after intrusion, the twist knuckle 14 does not exist and is not restored, so that traces of intrusion can be left at a glance, which is effective for early detection of an intrusion case.

勿論、菱形金網１１の上辺部に形成したツイストナックル１４は、他人が当該フェンスを乗り越えようとする場合に必要な、胴縁１３を掴む手がかりの場を制限して、侵入防止に効果をあらしめる。一方、菱形金網１１の下辺部に下向きに形成したツイストナックル１４は、地面１５との隙間を塞ぐので、野良猫や野犬、ネズミ、イタチ、モグラなどの小動物が当該フェンスの下を潜って侵入することを防ぐ効果を奏する。   Of course, the twist knuckle 14 formed on the upper side of the diamond-shaped wire mesh 11 limits the place of a clue to grasp the rim 13 required when another person tries to get over the fence, and has an effect of preventing intrusion. . On the other hand, the twist knuckle 14 formed downward on the lower side of the diamond-shaped wire mesh 11 closes the gap with the ground 15, so that small animals such as stray cats, dogs, rats, weasels, moles, etc. can enter under the fence. This has the effect of preventing

線材を菱形に編み込んで作られた菱形金網１１を柵に使用する。菱形金網１１の上辺部に、線材を捻って先端を二股形状に開いたツイストナックル１４を形成し、該ツイストナックル１４の直下位置の左右の菱形網目と分離された菱形網目１１ａをそれぞれ当該菱形金網１１の網面に対して直角な向きに捻り、前記直角な向きの菱形網目１１ａに胴縁１３を通し、この胴縁１３の両端部を支柱１２に支持させる。
菱形金網１１の下辺部にもツイストナックル１４を地面１５にほぼ接近する長さに形成し、該ツイストナックル１４の直上位置の左右の菱形網目と分離された菱形網目１１ａをそれぞれ当該菱形金網１１の網面に対して直角な向きに捻り、前記直角な向きの菱形網目１１ａに胴縁１３を通し、該胴縁１３の両端部を支柱１２に支持させる。
前記胴縁１３には鋼製で丈夫な丸パイプ１３Ａ又は角パイプ１３Ｂを使用する。 A rhombus wire mesh 11 made by weaving a wire into a rhombus is used for the fence. The upper portion of the rhombic wire mesh 11, to form a twisted knuckle 14 open tip bifurcated twist the wire, respectively the rhombic wire mesh left diamond mesh and separated rhombic mesh 11a and immediately below the position of the twist knuckle 14 twisting perpendicular orientation to the network surface 11, prior to passing the furring strip 13 to Kijika angle orientation diamond mesh 11a, thereby supporting both ends of the furring strip 13 to the column 12.
A twist knuckle 14 is also formed on the lower side of the rhombic wire mesh 11 so as to have a length substantially approaching the ground 15, and the left and right rhombic meshes 11a separated from the right and left rhombic meshes immediately above the twist knuckle 14 are respectively connected to the rhombic wire mesh 11 twisting perpendicular orientation relative to the network side, before Kijika angle orientation diamond mesh 11a through the furring strip 13, thereby supporting both ends of the barrel edge 13 to the column 12.
For the body edge 13, a strong round pipe 13A or square pipe 13B made of steel is used.

以下に、図示した本発明の実施例を説明する。
図１と図２は、本発明に係る侵入防止用フェンスの設置状態を示す。金属線材を菱形に編み込んで作られた菱形金網１１を柵に使用している。菱形金網１１の上辺部および下辺部を支持する胴縁１３は、その両端部が左右の支柱１２、１２に支持されている。地中のコンクリート基礎１０へ固定して垂直に立てた支柱１２の上端部であって菱形金網１１の上辺よりも更に上方の部分１２ａは、忍び返し１６として外側へ約３０°に傾斜され、左右の傾斜部分１２ａの間に、３本（但し、本数はこの限りではない。）の有刺鉄線１７を水平方向に平行に適度な間隔をあけて取り付け、忍び返し１６が形成されている（請求項４に記載した発明）。 Hereinafter, illustrated embodiments of the present invention will be described.
1 and 2 show an installation state of an intrusion prevention fence according to the present invention. A rhombus wire mesh 11 made by weaving a metal wire into a rhombus is used for the fence. The body edge 13 that supports the upper side and the lower side of the diamond-shaped wire mesh 11 has both ends supported by left and right columns 12, 12. The upper end portion 12a of the column 12 fixed to the underground concrete foundation 10 and erected vertically and further above the upper side of the rhombic wire mesh 11 is inclined outward by about 30 ° as a sneak-back 16 and Three (but not limited to) barbed wires 17 are attached between the inclined portions 12a in parallel in the horizontal direction at appropriate intervals to form a sneak-back 16 (claim 4 ). Invention described in (1).

菱形金網１１の上辺部及び下辺部には、図３Ｂに拡大して詳示したように、金属線材を捻って立て、先端を二股形状に開いて、いわば有刺鉄線の棘に等しい形態としたツイストナックル１４が網目のピッチで多数密に形成されている。そして、前記ツイストナックル１４の直下位置および直上位置の左右の菱形網目と分離された菱形網目１１ａがそれぞれ、当該菱形金網１１の網面に対して直角な向きに捻られており、これら直角な向きの菱形網目１１ａの中に胴縁１３が通されている。該胴縁１３の両端部は左右の支柱１２、１２間に支持されている（図４も参照＝請求項１記載の発明）。 On the upper side and lower side of the diamond-shaped wire net 11, as shown in detail in FIG. 3B, the metal wire is twisted and raised, and the tip is opened in a forked shape, so that the shape is equivalent to the barbed wire spines. A large number of twist knuckles 14 are densely formed at a mesh pitch. The left and right rhombic meshes 11a separated from the right and left rhombic meshes immediately below and directly above the twist knuckle 14 are respectively twisted in a direction perpendicular to the mesh surface of the rhombic wire mesh 11, and these perpendicular directions are used. The waist edge 13 is passed through the rhombic mesh 11a. Both ends of the body edge 13 are supported between the left and right columns 12, 12 (see also FIG. 4 = the invention of claim 1 ) .

因みに、菱形金網１１の菱形網目１１ａの大きさは、一辺の内法寸法が５０ｍｍ程度の略正方形とされている。したがって、前記ツイストナックル１４は７０ｍｍ程度の密なピッチで多数並立することになり、侵入者が胴縁１３を掴んでよじ登ろうとする手掛かりの場を制限し、侵入の防止に実効をあらしめる。そして、上記のように菱形網目を直角方向に捻って胴縁１３を通す場合、前記大きさの菱形網目１１ａには、胴縁１３として最大外径が４０ｍｍ程度、少し余裕を考慮しても外径が３４ｍｍ程度の頑丈な鋼製の丸パイプ１３Ａを図４Ａ、Ｂのように通すことができ、その両端部を支柱１２へ図３Ａ、Ｂのように支持させて強固なフェンスを構築し設置することができる。
或いは図４Ｃのように、胴縁１３として、最大外径が一辺４０ｍｍ程度、少し余裕を考慮しても一辺が３５ｍｍ程度の頑丈な鋼製の角パイプ１３Ｂを通して使用することもできる（請求項３に記載した発明）。 Incidentally, the size of the diamond-shaped mesh 11a of the diamond-shaped wire mesh 11 is substantially a square having an inner dimension of about 50 mm on one side. Therefore, a large number of the twist knuckles 14 are arranged side by side at a close pitch of about 70 mm, thereby limiting the place of clues where an intruder grasps the torso 13 and tries to climb up, which is effective in preventing intrusion. When the rhombic mesh is twisted in the right angle direction and passes through the trunk 13 as described above, the rhombic mesh 11a having the above-mentioned size has a maximum outer diameter of the trunk 13 of about 40 mm, and even if a margin is considered, As shown in FIGS. 4A and 4B, a sturdy steel round pipe 13A having a diameter of about 34 mm can be passed through, and both ends are supported on the support 12 as shown in FIGS. can do.
Or, as in Figure 4C, as the furring strip 13, the maximum outer diameter of about one side 40 mm, can also be side even considering a little margin used throughout rugged steel square pipe 13B of about 35 mm (claim 3 Invention described in (1).

胴縁１３の両端部を支柱１２へ支持させる構造は、一例を図３Ａ、Ｂに拡大して示したように、支柱１２の該当位置に、支柱１２を左右方向へ貫通する通しボルト１８とこれにねじ込んだナット１９とにより、支柱１２の左右両側に対称な配置で一対の筒状ブラケット２０が取り付けられる。菱形金網１１の上辺部及び下辺部に配置した上記の胴縁１３は、その両端部を支柱１２の該当する筒状ブラケット２０の孔へ差し込んで接続した後、直径方向に貫通させた止めボルト２１とナット２２で緊結して固定される。菱形金網１１の縦辺は、図３Ｂ、Ｃに例示したように、当該菱形網目１１の網厚Ｓ（図３Ｃ、図４ＢのＳ寸法を参照）を利用してフラットバー２３が網目に通され、該フラットバー２３は、支柱１２の上下方向に複数配置されたクランプ２４により支柱１２に支持されている。   As shown in FIGS. 3A and 3B, an example of a structure for supporting both ends of the torso 13 on the support 12 is a through bolt 18 that penetrates the support 12 in the left-right direction at a corresponding position of the support 12. A pair of cylindrical brackets 20 are mounted on the left and right sides of the column 12 in a symmetrical arrangement with the nuts 19 screwed into the column. The above-mentioned body edge 13 arranged on the upper side and the lower side of the diamond-shaped wire mesh 11 is connected by inserting both ends into the holes of the corresponding cylindrical bracket 20 of the support column 12 and then diametrically penetrated by the stop bolt 21. And a nut 22 for tightness and fixation. As illustrated in FIGS. 3B and 3C, the vertical side of the diamond-shaped wire mesh 11 is passed through the flat bar 23 using the mesh thickness S of the diamond-shaped mesh 11 (see the S dimension in FIGS. 3C and 4B). The flat bar 23 is supported by the column 12 by a plurality of clamps 24 arranged in the vertical direction of the column 12.

その具体的構造を、図３Ｃに示した。クランプ２４は、支柱１２の外周円形状に沿って二つ割り型に形成すると共に両端部に平坦な重ね合わせ部を形成して成る一対の半割部材２４Ａ、２４Ｂから成る。前記一対の半割部材２４Ａ、２４Ｂで支柱１２の外周を挟み付け、両端部の平坦な重ね合わせ部にて上記のフラットバー２３の前後両面を挟む。場所によっては菱形金網１１の線材も併せて挟み付け、ボルト２５とナット２６を緊結して拘束と支持が行われている。なお、菱形金網１１の中間部分を支持する骨線２８の端部も、前記のクランプ２４により合一に支持される。   The specific structure is shown in FIG. 3C. The clamp 24 is formed of a pair of half members 24A and 24B which are formed in two halves along the outer circumferential shape of the column 12 and have flat overlapping portions at both ends. The outer periphery of the column 12 is sandwiched between the pair of half members 24A and 24B, and the front and rear surfaces of the flat bar 23 are sandwiched between flat overlapping portions at both ends. Depending on the location, the wire of the rhombic wire net 11 is also sandwiched, and the bolt 25 and the nut 26 are tightly connected to each other to perform restraint and support. The end of the bone line 28 supporting the intermediate portion of the diamond-shaped wire mesh 11 is also unitedly supported by the clamp 24.

本発明の侵入防止用フェンスは、図３Ｂに示したように、菱形金網１１の下辺部にもツイストナックル１４が地面１５にほぼ接近する長さに形成されている。そして、該ツイストナックル１４の直上位置の左右の菱形網目と分離された菱形網目１１ａがそれぞれ当該菱形金網１１の網面に対して直角な向きとなるように捻られ、この直角な向きの菱形網目１１ａに胴縁１３を通して、該胴縁１３の両端部が支柱１２に支持されている（請求項２に記載した発明）。前記胴縁１３の両端部を支柱１２へ支持させる構造は、上記した上辺の胴縁１３の支持構造と同じである。下辺部の下向きのツイストナックル１４が地面１５との間の隙間を全面的に塞ぐので、野良猫や野犬、ネズミ、イタチ、モグラなどの小動物がフェンスの下を潜って侵入することを確実に防止するのである。 As shown in FIG. 3B, the intrusion prevention fence of the present invention is also formed with a length such that the twist knuckle 14 is substantially close to the ground 15 also at the lower side of the diamond-shaped wire mesh 11. Then, the left and right diamond mesh and separated rhombic mesh 11a immediately above the position of the twist knuckle 14 is twisted so as to be perpendicular orientation relative to each mesh surface of the diamond-shaped wire mesh 11, this right angles orientation of The body edge 13 is passed through the rhombic mesh 11a, and both ends of the body edge 13 are supported by the columns 12 (the invention described in claim 2 ). The structure for supporting both ends of the body edge 13 on the support pillar 12 is the same as the support structure for the upper body edge 13 described above. The downward twist knuckle 14 on the lower side completely blocks the gap between the ground 15 and ensures that small animals such as stray cats, dogs, rats, weasels, moles, etc. do not enter under the fence and invade. It is.
