Description

本発明はネットフエンスの胴縁に忍返しをとりつけた防犯用フエンスを提供する。The present invention provides an anti-crime fens with an endurance attached to the rim of the net fens.

従来ネットフエンスは公知である。しかして該フエンスの胴縁に、防犯のために上方に剣先部を所定間隔をもって長手方向に多数起立している取付部（通称この種構造のものを忍返しと言う、以下忍返しと言う）をボルトナットの止具を介して取付けた防犯用フエンスは公知である。
実用新案登録 第３０９９７８６ Conventional net fences are known. Therefore, on the body edge of the fens, a mounting part in which a number of sword tips are raised in the longitudinal direction at a predetermined interval for the purpose of crime prevention (commonly referred to as this type of structure is called endurance, hereinafter referred to as endurance) Crime prevention fences are known which are attached via bolt and nut fasteners.
Utility model registration No. 3099786

上記従来の防犯用フエンスはフエンス本体の円形の胴縁の両側に、直に忍返しの取付金具及び受金具を当接し、ボルトナットによる止具で締着する構造であるので、これら取付金具および受金具は胴縁に沿う円形にし、所定のボルト挿通孔にボルトを水平方向に貫通して強固に締着する構造にしていた。The conventional crime prevention fens have a structure in which a reversing mounting bracket and a receiving bracket are brought into direct contact with both sides of the circular body edge of the main body of the fens and are fastened with bolts and nuts. The support metal is circular along the trunk edge, and has a structure in which a bolt is horizontally passed through a predetermined bolt insertion hole and firmly tightened.

ところが上記従来の忍返しは、予め設計された所定の長さを有し、取付金具の長手方向に沿ってボルト挿通孔を所定の間隔をもって予め形成しているが、該忍返しを胴縁に取付ける際、場合によっては胴縁の縦線材又は横線材が、ボルト挿通孔の箇所に位置しているためにボルトが貫通できず、施工現場においてボルトの挿通孔を新たに開孔しなければならず、作業の煩わしさがあった。さらにまた胴縁への割付寸法が合わず、忍返しを短く切断して使用する場合、新たにボルト挿通孔の開孔作業を要する等の欠点があった。However, the above conventional flip has a predetermined length designed in advance, and bolt insertion holes are formed in advance along the longitudinal direction of the mounting bracket at predetermined intervals. When installing, depending on the case, the vertical or horizontal wire rod is located at the bolt insertion hole, so the bolt cannot penetrate, and the bolt insertion hole must be newly opened at the construction site. The work was troublesome. Furthermore, there is a drawback in that, for example, when the size of the barrel edge is not suitable and the endurance is cut short and used, it is necessary to newly open the bolt insertion hole.

さらにまた取付金具に形成しているボルト挿通孔が長孔でなくボルト軸の大きさの丸孔であるために、孔内で移動ができず、ややもすると胴縁の縦線材又は横線材に触れて挿通できなかったり、あるいはボルト軸が横線材の下側に支持される状態でとりつけることが安定した取り付けであるが、空隙の中間に位置してとりつけられるために固定が不安定になることがあった。Furthermore, since the bolt insertion hole formed in the mounting bracket is not a long hole but a round hole of the size of the bolt shaft, it cannot move within the hole, and it may be a vertical or horizontal wire on the trunk edge. Can be inserted without touching, or can be installed in a state where the bolt shaft is supported on the lower side of the horizontal wire, but it is mounted in the middle of the gap, so the fixing becomes unstable was there.

本発明はつぎの特徴を備えている。
その一つは「所定間隔に配される縦線材と、該縦線材に横線材を組格してなるネットフエンスであり、該フエンスは上部に環状の胴縁を形成しており、該胴縁は該縦線材の端部を折曲して形成しているリングの内側に横線材を数本溶接して形成しており、上記胴縁には忍返しが上方に起立して取り付けられており、上記忍返しは金属棒材を溶接で縦横に組格して所望長さに形成されており、下部には上記環状の胴縁に当接してとりつけられる取付部が形成されており、該取付部は上下２本の棒材と縦の棒材からなり、所定長さと所定巾の大きさに形成されているボルト挿通用の空間部が長手方向全長にわたって複数個形成されており、上記胴縁に忍返しの取付部が当接した状態でその取付部にたて長孔のボルト挿通孔を有する受具が取付部の空間部を上下２本の棒材にまたがってとりつけられ、胴縁の対向側には当て材と受具本体からなる受具がとりつけられ、上記当て材は胴縁に当接して縦線材間にまたがってとりつけられ、その外側に受具本体が取り付けられ、受具のボルト挿通孔、取付部のボルト挿通用の空間部、胴縁の空隙部、受具の当て材および受具本体のボルト挿通孔をそれぞれボルト軸が貫通してナットで締着されることを特徴とする防犯用フエンス」である。The present invention has the following features.
And vertical wire One of which is arranged in a "predetermined distance, a Nettofu et Nsu formed by Kumikaku the horizontal member to said longitudinal wires, the fence forms a circular furring strip at the top, the barrel The edge is formed by welding several horizontal wires to the inside of the ring formed by bending the end of the vertical wire. The endurance is formed in a desired length by welding metal bars vertically and horizontally, and a lower portion is formed with a mounting portion that contacts and attaches to the annular trunk edge, The mounting portion is composed of two upper and lower bars and a vertical bar, and a plurality of bolt insertion spaces formed in a predetermined length and a predetermined width are formed over the entire length in the longitudinal direction. In the state where the reversing attachment part is in contact with the edge, the receiving tool having a long bolt insertion hole is attached to the attachment part. The intermediate part is attached to two upper and lower bars, and a receiving member consisting of a backing material and a receiving body is attached to the opposite side of the body edge. The receiver body is attached to the outside, and the bolt insertion hole of the receiver, the space for inserting the bolt in the attachment part, the gap part of the trunk edge, the pad material of the receiver and the bolt insertion of the receiver body This is a crime prevention fuse characterized in that a bolt shaft passes through each hole and is fastened with a nut .

その二つは「所定間隔に配される縦線材と、該縦線材に横線材を組格してなるネットフエンスであり、該フエンスは上部に環状の胴縁を形成しており、該胴縁は該縦線材の端部を折曲して形成しているリングの内側に横線材を数本溶接して形成しており、上記胴縁には忍返しが上方に起立して取り付けられており、上記忍返しは金属板材を用いており、取付部は胴縁の形状に沿ってとりつけられるように形成されており、取付部の全長にわたって複数個のボルト挿通用の空間部が、ボルトの取付位置が長手方向において自由度があり、高さ方向において自由度があるように形成されており、上記胴縁に沿って取付部が取り付けられ、胴縁の対向側に当て材と受具本体からなる受具が取り付けられ、上記当て材は胴縁に当接して、縦線材間にまたがってとりつけられ、その外側に受具本体が取り付けられ、取付部のボルト挿通用の空間部、胴縁の空隙部、受具の当て材および受具本体のボルト挿通孔をそれぞれボルト軸が貫通してナットで締着されることを特徴とする防犯用フエンス」である。 A longitudinal wire that two are to be arranged in a "predetermined distance, a Nettofu et Nsu formed by Kumikaku the horizontal member to said longitudinal wires, the fence forms a circular furring strip at the top, the barrel The edge is formed by welding several horizontal wires to the inside of the ring formed by bending the end of the vertical wire. The endurance uses a metal plate, and the mounting portion is formed so as to be attached along the shape of the trunk edge, and a plurality of space portions for inserting bolts are provided over the entire length of the mounting portion. The mounting position has a degree of freedom in the longitudinal direction and has a degree of freedom in the height direction. A mounting part is attached along the trunk edge, and the contact material and the receiving body on the opposite side of the trunk edge The above bracing material is abutted against the trunk edge and placed between the vertical wire rods. The bolt body is attached to the outside, the bolt body is attached to the outside, and the bolt shaft is inserted into the bolt insertion space of the attachment part, the gap part of the trunk edge, the backing material of the holder and the bolt insertion hole of the receiver body. It is a crime prevention fenance characterized by being penetrated and fastened with a nut .

本発明の防犯用フエンスは、胴縁に固定される忍返しがボルト、ナット等の止具によって締着されるに当たり、胴縁への取付部に長手方向全長にわたって複数個の所定長さのボルト挿通用空間部を形成し、該空間部の適宜の位置及び胴縁の空隙部をボルトが貫通してナットで締着されるので、従来の丸孔の挿通孔のようにボルト軸が縦線材や横線材に邪魔されて挿通できなくなるなどの虞もなく確実に固定できる。The crime prevention fen of the present invention has a plurality of bolts of a predetermined length over the entire length in the longitudinal direction at the attachment portion to the trunk edge when the turnover fixed to the trunk edge is fastened by a fastener such as a bolt or nut. Since a space for insertion is formed, and the bolt passes through an appropriate position in the space and a gap at the body edge and is tightened with a nut, the bolt shaft is a vertical wire rod like a conventional round hole. It can be fixed securely without the possibility of being blocked by the horizontal wire and being unable to pass through.

さらに本発明の防犯用フエンスは、忍返しの胴縁への割付寸法が合わず、忍返しを所定の長さに短く切断して使用する場合でもボルト挿通用の空間部が全長にわたって形成しているので、新たにボルト挿通用の開孔作業をしなくてもボルト締着ができ施工作業の煩わしさがない。In addition, the crime prevention fens of the present invention does not match the size of the flipped body rim, and even when the spine is cut into a predetermined length, the space for bolt insertion is formed over the entire length. As a result, the bolt can be fastened without the need for new hole insertion work for bolt insertion, and there is no troublesome construction work.

さらにまたボルト挿通用の空間部が巾方向、つまり高さ方向に、所定巾の大きさに又は複数個形成しているので、ボルトの取付け位置が上下に加減でき、よって胴縁の横線材が障害になることもなく、むしろ横線材の下側に位置して締着できるので、ボルトの緩みもなく安定した固定ができる。Furthermore, since the space for bolt insertion is formed in the width direction, that is, in the height direction, with a predetermined width or a plurality of widths, the bolt mounting position can be adjusted up and down, so that the horizontal wire on the trunk edge Since it can be fastened to the lower side of the horizontal wire without causing an obstacle, it can be stably fixed without loosening of the bolt.
