Description

[Detailed description of the invention] This invention mainly relates to a device for hanging small wires to the peripheral lines of fruit tree shelves such as pears and peaches.

Generally, in orchards of pears, peaches, etc., fruit tree trellises are installed throughout the orchard to protect fruit tree branches, facilitate fruit management, and prevent birds.

Normally, this type of fruit tree shelf has one support made of steel pipes etc. placed at approximately equal intervals around the orchard, as shown in Figure 1.
are erected, and a perimeter line 2 is stretched over the upper end of each of the columns 1, and a trunk line 3 is stretched between the opposing columns 1, and a large number of lines are placed between the opposing perimeter lines 2. It is constructed by stretching Kobari wire 4. The peripheral wire 2 and main wire 3 are made of thick steel wire with a diameter of about 4 to 8 mm, and the small wire 4 is made of a thin steel wire with a diameter of about 2 mm.

By the way, each small bari wire 4 is conventionally fastened to the surrounding wire 2 as shown in FIG.
The end of the wire was directly wrapped around the surrounding wire 2 several times, and then the tip was brought back and twisted around the wire 4 itself many times like a vine.

For this reason, it is very troublesome and time-consuming to tighten and tighten the Kobari wire 4 to the surrounding line 2, and once it is tightened, it is difficult to adjust the tension after that. However, the work of installing the Kobari wire 4 was troublesome, inefficient, and required a lot of time. In addition, there were also problems such as the folded and wrapped end of the bari wire 4 protruding upward and getting caught when a bird prevention net (not shown) was placed over the upper side of the fruit tree shelf.

This invention was created in view of the above circumstances, and its purpose is to be able to hang the Kobari wire very easily and reliably to the surrounding wire, and to
To provide a highly practical hanging tool that allows easy tension adjustment afterwards, greatly improves work efficiency, and eliminates inconveniences such as getting caught when covering a bird-prevention net.

In other words, the hanging device for the tension wire for fruit tree shelves of this invention is
A spiral winding part with a small inner diameter and a large pitch that has a winding part that can be loosely inserted into the surrounding wire, and which extends long from the winding part and can entangle the small wire. A hook part that extends short in the same direction as the winding part and substantially parallel to the winding part, and has a folded-back end on which the tip of the small wire can be hooked, and the entire hook part is made of a single elastic steel wire. It is.

An embodiment of this invention will be described below with reference to FIGS. 3 to 5. The small wire 4 is fastened to the surrounding wire 2 via a hook 5, which is similar to the conventional one.
This hanging tool 5 is entirely constructed by bending a single elastic spring steel wire with a diameter of approximately 2 mm, which is approximately the same as the small wire 4, and the proximal end is as shown in FIGS. 4 and 5. A winding part 6 of the section, a long vine winding part 7 extending from one of the winding parts 6, and a short vine winding part 7 extending from the other winding part 6 substantially parallel to the same direction as the vine winding part 7. It has an extended hook portion 8. More specifically, the winding portion 6 is formed by winding a spring steel wire approximately twice in the middle in a slightly elliptical shape, and has an inner minor axis D of approximately 10 mm, and a peripheral wire 2 having a diameter of approximately 8 mm. Can be inserted loosely. Further, a tendril winding part 7 extending long from one side of the spring steel wire of this winding part 6 is bent in a spiral shape around a straight axis from halfway toward the winding part 6 side to the tip. . The number of spiral turns is 5-6
The inner diameter E is approximately the same as the diameter of the wire 4, and the pitch P is approximately 10 times larger than the inner diameter E. Also,
A short hook part 8 extending from the other side of the spring steel wire of the winding part 6 has its tip folded back into a hairpin shape, and the folded inner diameter F is about 5 to 6 mm.

Therefore, using the above-mentioned hanging tool 5, the Kobari wire 4 is attached.
When fastening to the surrounding wire 2, first loosely insert the winding part 6 of the hook 5 into the surrounding wire 2,
In this state, slide the hanging tool 5 to the position where the wire is attached to the peripheral wire 2, and while pulling the end of the wire 4, attach the coiled wire part 7 of the hanging tool 5 from its tip. The tip of the small bari wire 4 pulled out from the final spiral near the proximal end of the coiled wire portion 7 is inserted into the hook portion 8.
Pass it through the inside of the folded end of the holder and pull it strongly to bend it.

This completes the fixing of the small bari wire 4 to the peripheral line 2, and during the fixing, the proximal end side of the coiled wire part 7 and the hook part 8 are pulled together by hooking the tip of the small bari wire 4. By being rotated, the winding part 6
The short diameter D of the inner periphery is elastically narrowed, and it is tightly attached to the surrounding wire 2 and becomes immovable. Even if tension is applied, it will not come off at all. With this, the small bari wire 4 can be easily and securely fastened to a desired location on the peripheral wire 2. If you want to readjust the tension of the Kobari wire 4 after it has been fastened, you can do so by simply removing the tip of the Kobari wire 4 from the hook part 8 and loosening the tension from the coiled wire part 7. At the same time, sliding adjustment with respect to the peripheral line 2 is also possible. In addition, when fastening the above-mentioned Kobari wire 4, the hanging tool 5
If the hanging part 5 is attached to the surrounding wire 2 so that the coiled wire part 7 is on the upper side and the hook part 8 is on the lower side, the tip of the small bari wire 4 will not protrude upward, and the bird prevention net will be No more getting caught when putting it on.

Since this invention has been developed as described above, it is possible to easily and reliably hook the shobari wire to the surrounding wire, and it is also easy to adjust the tension afterwards, which greatly improves the efficiency of the shobari wire installation work, and also prevents birds. There is no inconvenience such as getting caught when covering the net for business, etc.
It is very practical and simple.
