Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to overhead wire equipment for pasture fences.
This invention relates to an overhead line tool for pasture fences that can be detachably fixed to the posts of pasture fences and can support overhead wires spanning between the posts.

[Prior art and problems that the invention attempts to solve]

Traditionally, posts of various shapes have been used for fences to separate animals on farms, but among them, cylindrical posts are widely used because they are relatively economical and have excellent strength. . A pasture fence is formed by spanning wires over such posts, and various methods of fixing the wires to the posts have been considered in the past. Furthermore, various methods have been considered for fixing electric fences to the posts, in which electric current is passed through the wires.

However, among the conventional cylindrical pillars mentioned above, the pillars for electric fences have various problems, such as the wire contact surface being rounded in the cylindrical ones, making it impossible to securely secure the wires, and insufficient insulation. Ta. In other words, for pasture fences whose supports are not made of insulators, see Figures 11 to 1.
There is something like the one shown in Fig. 3, but the one shown in Fig. 11 in which a plastic sheet 5 is wrapped around the support 4 and the wire W is spanned using this as an insulating material has insufficient insulation and the wire W is stretched over it. There is a problem that if the W becomes loose, it will slip off the seat 5, and the insulator 6 shown in FIG.
At first glance, an electric pasture fence that is fixed to the fence and the wire W is stretched over it seems to have sufficient insulation performance, but when a cow or other pasture accidentally enters the fence, the arm 2 bends and the wire W There is a problem that the insulator 7 is easily attached to the support column 4 and causes an electric leak, and the insulator 7 shown in FIG. In addition to the wire W coming into contact with the support column 4 and causing electrical leakage,
This type of support has a problem in that the height of the wire W cannot be easily changed because the support post 4 is attached by making a hole, and neither support support is sufficient for use as an electric fence.

Additionally, as shown in Figures 14 to 16, there are electric fences that use insulators for the posts themselves.
Connect the wire W to the support 4 using the binding wire 8 shown in FIG.
In the case of overhead wires, there are problems in that the wire W tends to slip off and easily come off when cattle rush towards the wire W, so the wire W is passed through a hole 3 made in the support 4 shown in Fig. 15. The problem with this method is that it takes time to pass the wire W through the hole 3, it takes time to repair it when it breaks, and the strength of the support 4 decreases because the hole 3 is made in the support 4.
The structure in which wire tie fittings 9 are used for the strut 4 shown in the figure has problems such as the wire W cannot be adjusted to a high degree and the strength of the strut is reduced.

(Means for Solving the Problems) The purpose of the present invention is to solve the problems between the pillars and the wires connected thereto when forming the conventional electric fence, and to facilitate the installation of the overhead wires. To provide an excellent overhead line tool for pasture fences, which allows wires to be securely fixed to a support, allows the installation position of the overhead wire to be easily changed, and does not weaken the strength of the support.

The overhead wire equipment for pasture fences of the present invention that achieves the above-mentioned purpose is as follows:
A body made of a filament made of an elastic material of a predetermined length and wound multiple times in a spiral shape, and an arm that protrudes laterally from both ends of the body and has a ring hole through which a wire can be inserted. It is characterized by having a section.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIGS. 1a and 1b are a plan view and a side view showing the structure of an embodiment of the overhead line tool for pasture fences of the present invention.

The fence wire tool 10 of this embodiment is made by processing a wire of a predetermined length of an elastic material such as spring steel, and is formed by winding the center portion of the wire multiple times in a spiral shape. The arm part 12 is formed by making both ends of the filament protrude from the body part 11 to the sides thereof. And the arm portion 1
2 is provided with a ring hole 13 formed by winding a filament at least half a turn, and a wire used for the pasture fence is inserted into the ring hole 13.

In this embodiment, one of the arms 12, for example, the one at the start of the spiral, is curved after protruding to the side of the body 11, and its tip is formed to be located at the end of the spiral. has been done. Further, one of the arm portions 12 is curved after protruding from the winding end side of the spiral to the side of the body portion 11, and is formed such that its tip is located at the winding start side of the spiral. The two ring holes 13 formed by the curved arm portions 12 are located opposite to each other at a predetermined angle.

Furthermore, when the two arm parts 12 are urged from outside to inside, the helix of the trunk part 11 is twisted, the inner diameter of the trunk part 11 is expanded, and the arm parts 12 When the bias is released, the trunk 1
The inner diameter of 1 shrinks and returns to its original diameter. Therefore, when attaching this overhead line tool 10 for pasture fences to a post, pass the body part 11 with an enlarged inner diameter through the post while applying pressure to the arm part 12, and release the pressure on the arm part 12 at the desired attachment position. Then, the cattle fence overhead line tool 10 is fixed to the support at that position.

The cattle fence overhead line tool 10 of this embodiment configured as described above is attached to the pillar 14 as shown in FIG. , wire W is held on the post.
In this method, the wire W is held loosely in the ring hole 13 of the arm 12, so if cattle collide with the cattle fence that has been wired in this way, the wire W will slide and the support post 14 will be damaged. Less is.

In addition to the overhead wire method described above, as shown in FIGS. 3a and 3b, the wire W is passed through one ring hole 13, but the wire W is not passed through the other ring hole 13. If the wire W is biased by the curved portion 12a, the wire W can be attached to the support column 14 while being retained.

FIG. 4 shows an example in which a plurality of overhead wire tools 10 for pasture fences of this embodiment are used for one support 14. As described above, the overhead wire tool 10 for pasture fences of this embodiment can be easily attached to and detached from the supports 14, so the spacing between the overhead wires can be set freely, and any number of wires W can be connected at narrow intervals as a pasture fence. If the distance between the wires W is narrowed as in the pasture fence 1 shown in FIG. 5, it will be effective against fairly small animals such as squirrels and small birds.

In addition, in carrying out the above-mentioned second overhead wire method, in order to prevent the wire W from coming off from the arm part 12 through which the wire W is not inserted, the curved part 12a of the arm part 12 is shown in FIG. It may also be formed in a concave shape. Further, the above explanation is for the case where the support 14 is made of an insulating material such as a pile made of glass fiber, but if the support 14 is a spring tail pole made of a flexible conductive metal, for example, , as shown in FIG. 7, the attachment portion of the overhead wire for pasture fence 10 may be covered with an insulating tube 15.

FIGS. 8a and 8b show another embodiment of the overhead wire tool 10 for pasture fences according to the present invention. The above-mentioned arm part 12 of the cattle fence overhead line tool 10 of this example projects on the completely opposite side to the body part 11. Therefore, when the wire W is inserted into both ring holes 13, The wire W is constructed so as to bypass the support 14 and is locked to the support 14.

FIGS. 9 and 10 show still another embodiment of the overhead fence wire tool 10 of the present invention. The ring hole 13 of the overhead fence wire tool 10 in these figures is formed by winding the wire one or more times in the form of a wire, and in the one shown in FIG. They are located at the winding start side and the winding end side of the helix, and are designed to allow two separate wires W ₁ and W ₂ to be inserted and held, respectively. One wire W on the same side of 11
It is designed to be inserted and held. When a pasture fence is formed using the overhead fence wire tool 10 shown in FIG. 9, it becomes a pasture fence that feels thick. Further, if a guideline such as a knot 16 is provided at a predetermined position of the support 14, an appropriate height of the overhead wire can be easily determined. In the cattle fence overhead wire 10 shown in Fig. 10, when a weight of more than a predetermined value is applied to the wire W, the grip force of the spiral body 11 decreases and it slides downward, so there is no damage to the cattle fence and it is snow resistant. It has high utility value as an overhead line tool for pasture fences.

As described above, although there are various embodiments of the fence wire tool 10 of the present invention, the present invention is not limited to these.

[Effect of idea]

As explained above, according to the overhead wire for pasture fences of the present invention, the following effects are produced.

It is easy to connect overhead wires and can be done easily.

Since the position of the overhead wire can be easily changed, changes in the spacing between overhead wires and the number of tiers can be made immediately.

There is no need to process the pillars, and the strength of the pillars does not deteriorate.
