Description

ところが、特許文献１では、ワイヤーの支持具を樹木の幹に取り付ける際に、支持具を釘部材で幹に打ち付けることによって固定しているので、釘部材によって樹木が傷むという課題があった。また、金属製の支柱等と異なり、樹木には地面に対して垂直でないものがある上に、支柱の設置場所に生える樹木の直径が一定ではないので、支持具を取り付けることが可能な樹木が限られるという課題がある。更に、木にこぶがある場合には、樹木の表面に凹凸があり、枝があれば取り付けることができないので、樹木には支持具の取付場所に制約があるという課題もあった。 However, in Patent Document 1, when the wire support is attached to the trunk of the tree, the support is fixed by striking the trunk with a nail member, so that there is a problem that the tree is damaged by the nail member. Also, unlike metal stanchions, some trees are not perpendicular to the ground, and the diameter of the trees that grow at the stanchion installation location is not constant, so there are trees to which supports can be attached. There is the issue of being limited. Further, when the tree has a hump, the surface of the tree is uneven and cannot be attached if there are branches, so that there is a problem that the place where the support is attached is restricted in the tree.

本発明は、林間地や森林内へのフェンス設置、特に電気ワイヤーフェンスの設置に際して、樹木を傷めることなく、しかも樹木への取付場所の制約が少なく、更に簡単にワイヤーを樹木に取り付けることが可能であり、支柱を林間地や森林内にある樹木で代替することにより、ワイヤーフェンスの設置コストを低減することが可能なワイヤーの架線用碍子を提供することを目的とする。 According to the present invention, when installing a fence in a forest or in a forest, particularly when installing an electric wire fence, the wire can be easily attached to the tree without damaging the tree, and there are few restrictions on the attachment place to the tree. It is possible, and it is an object of the present invention to provide a wire overhead wire porcelain that can reduce the installation cost of a wire fence by substituting the pillars with trees in a forest area or a forest.

次に、架線用碍子１を支柱に取り付けるための筐体２の裏側の取付構造２０について説明する。取付構造２０には、図２（ｂ）に示されるように、ワイヤーの延伸方向に形成された左壁２１Ｌと右壁２１Ｒ、ワイヤーの延伸方向に対して平行な上壁２２Ｕと下壁２２Ｂがある。左壁２１Ｌ、右壁２１Ｒ及び上壁２２Ｕと下壁２２Ｂに囲まれた部分は凹部２３になっている。凹部２３内は、本実施例では上壁２２Ｕと下壁２２Ｂに平行な複数の隔壁２５（本実施例では隔壁数は４つ）によって複数区画２４に仕切られている。 Next, the mounting structure 20 on the back side of the housing 2 for mounting the insulator 1 for the overhead wire to the support column will be described. As shown in FIG. 2B, the mounting structure 20 includes a left wall 21L and a right wall 21R formed in the wire extending direction, and an upper wall 22U and a lower wall 22B parallel to the wire extending direction. be. The portion surrounded by the left wall 21L, the right wall 21R, the upper wall 22U, and the lower wall 22B is a recess 23. The inside of the recess 23 is partitioned into a plurality of compartments 24 by a plurality of partition walls 25 parallel to the upper wall 22U and the lower wall 22B (in this embodiment, the number of partition walls is four).

また、凹部２３内に設けられた４枚の隔壁２５のうち、隣接する外側の隔壁２５と内側の隔壁２５の間には、前述の第１湾曲凹部２６の両側部分に、筐体２の表側に向かう補強壁２８が設けられている。そして、この補強壁２８には、後述する取付具を挿通するための第２取付孔１４Ｂがそれぞれ設けられている。 Further, among the four partition walls 25 provided in the recess 23, between the adjacent outer partition wall 25 and the inner partition wall 25, the front side of the housing 2 is placed on both side portions of the first curved recess 26 described above. A reinforcing wall 28 is provided toward the wall. The reinforcing wall 28 is provided with a second mounting hole 14B for inserting a mounting tool described later .

一方、結束バンド６は２本使用し、幹が太い樹木の場合には、２本の結束バンド６は、左壁２１Ｌ及び右壁２１Ｒに設けられたカバー１７の内側にある第１取付孔１４Ａの一方から挿入し、架線用碍子１の内部を通過させて対向位置にある第１取付孔１４Ａから外に引き出すことによって、架線用碍子１に装着する。また、幹が細い樹木の場合には、図３（ｂ）に示すように、２本の結束バンド６を、２つの隔壁２５の間の部分にある補強壁２８に設けられた第２取付孔１４Ｂをそれぞれ挿通させた後に、反対側にあるもう１つの第２取付孔１４Ｂを挿通させることによって、架線用碍子１に装着する。なお、２本の結束バンド６は、架線用碍子１を樹木に取り付ける前に２つの第１取付孔１４Ａの間、或いは２つの第２取付孔１４Ｂの間に挿通しておく。この時、架線用碍子１を樹木に取り付ける前に２本の結束バンド６が架線用碍子１から抜け落ちないように、架線用碍子１に何らかの結束バンド６の抜け防止構造を採用することができるが、その構造、取付時の作業工程については本発明の趣旨ではないのでこれ以上の説明を省略する。 On the other hand, when two binding bands 6 are used and the trunk is a thick tree, the two binding bands 6 are the first mounting holes 14A inside the covers 17 provided on the left wall 21L and the right wall 21R. It is attached to the overhead wire insulator 1 by inserting it from one side, passing it through the inside of the overhead wire insulator 1, and pulling it out from the first mounting hole 14A at the opposite position. Further, in the case of a tree having a thin trunk, as shown in FIG. 3B, the two binding bands 6 are provided in the second mounting hole 28 provided in the portion between the two partition walls 25. After each of the 14Bs is inserted, the other second mounting hole 14B on the opposite side is inserted so as to be attached to the overhead wire insulator 1. The two binding bands 6 are inserted between the two first mounting holes 14A or between the two second mounting holes 14B before the overhead wire insulator 1 is attached to the tree. At this time, some kind of cable tie prevention structure can be adopted for the overhead wire insulator 1 so that the two binding bands 6 do not fall off from the overhead wire insulator 1 before the overhead wire insulator 1 is attached to the tree. Since the structure and the work process at the time of mounting are not the gist of the present invention, further description thereof will be omitted.
