Utility model registration No. 3099786

The conventional crime prevention fens described above 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 a bolt and nut. The support metal is circular along the body edge, and has a structure in which a bolt is horizontally passed through a predetermined bolt insertion hole and firmly tightened.

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 when the allocation dimension to the trunk edge is not suitable and the endurance is cut short and used, it is necessary to newly open the bolt insertion hole.

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 if it is somewhat longer, it will become a vertical or horizontal wire on the trunk edge. It cannot be inserted by touching it, or it can be installed in a state where the bolt shaft is supported on the lower side of the horizontal wire, but it can be fixed in the middle because it is installed in the middle of the gap. was there.

The present invention has the following features.
One of them is “the net fens formed by assembling the vertical and horizontal wires, the endurance that stands above the torso of the fuse, and the bolts and nuts for attaching the endurance to the torso. A stopper is formed, and a plurality of predetermined lengths of bolt insertion spaces are formed over the entire length in the longitudinal direction at the attachment portion to the trunk edge, and the space portion and the gap portion of the trunk edge are formed. It is a crime prevention fenance characterized in that the bolt penetrates and is fastened with a nut.

Two of them in the above-described configuration are “the endurance is made of a material such as a plate, a bar, etc., and the space for inserting the bolt has a predetermined width, or the bolt mounting position can be changed in the height direction, or It is a crime prevention fuse characterized by being formed in a plurality in the height direction.

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 securely fixed without fear that it will be blocked by the horizontal wire and cannot be inserted.

Furthermore, the crime prevention fens of the present invention does not match the size of the roll-up to the body edge, and even when the roll-up 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.

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 being obstructed, it can be stably fixed without loosening of the bolt.
