Description

[Detailed Description of the Invention] This invention relates to an end tensioning device for tensioning and securing the end of a wire or other wire material.

In fruit tree trellises such as grape trellises, it is necessary to stretch wire rods between the supports and tension them in order to make the vines creep, and for this reason there is a need for a tensioning tool that facilitates attachment of the ends of the wire rods.

This invention satisfies these demands and aims to provide a tensioning device that is easy to attach to a mounting pole and can securely lock the wire while tensioning it, with the center being omitted. The curved recesses 4a and 4b are formed by bending into a semicircle, and flat portions 2a x 3a *2b and 3b are formed on both sides of the recesses, and bolt holes 5a are provided in the flat portions.

A pair of bands Ia with holes 6a, 5b, and 6b.

1b to the mounting pole 12, insert the U-bolt 9 into the bolt holes in both flat parts, and tighten with the Nand 11 screwed into the U-shaped bent part and the tip of the U-bolt. and set pole 12 to band 1a.

This terminal tensioning device is characterized in that it is clamped and fixed at 1b, and the U-shaped bent portion of the U-bolt 9 is used as a hooking portion of a turnbuckle 13.

A detailed description will be given below with reference to the drawings.

In the figure, la and 1b are a pair of bands, each having flat portions 2a, 3a, 2b, and 3b on both sides, and curved recesses 4a and 4b are formed between the flat portions.

The flat parts have bolt holes 5a and 6a, respectively. 5b,
6b is drilled.

The upper edges of the curved recesses 4a and 4b project slightly upwards than the upper edge of the flat portion, and the camp 7 is placed over this S as necessary.

Note that 8a and 8b in the figure are lip-like protrusions formed over the entire surface of the band for the purpose of increasing the strength and aesthetics of the band.

The pair of bands la and 1b are fixed to the mounting pole 12 by Nandos 11 which are screwed into the U-bolt 9 and the tip of the U-shaped bent portion of the U-bolt threaded portion 10, respectively.

When installing, first tie the pair of bands 1a and lb from both sides of the mounting pole 12 and place them in the curved recesses 4a and 4.
Place the mounting pole 12 in a pinched state in the flat part of the bolt through hole 5a, t6a, 5b, 6b.
, and tighten the NAND 11 to fix the band to the mounting pole.

As a result, the U-shaped bent portion of the U-bolt 9 protrudes in the horizontal direction as shown in FIG. 2, and the end 14 of the wire rod is attached to this via the turnbuckle 13 and tensioned.

As described above, according to this invention, the curved recesses 4a and 4b are formed by bending into a substantially semicircular shape at the center, and the flat portions 2a are formed on both sides of the curved recesses 4a and 4b.
, 3a, 2b, 3b, and a pair of bands 1a with bolt holes 5a, 6a, 5b, 6b drilled in the flat parts.
, 1b to the mounting pole 12, insert the U-bolt 9 into the bolt through hole of both flat parts, and tighten with the Nand 11 screwed into the tip of the U-bolt at a position near the U-shaped bent part. Then, the mounting pole 12 is clamped and fixed by the bands 1a and Ib, and since the U-shaped bent part of the U-port 9 is used as the catch part of the turnbuckle 13, the terminal tensioning tool is fixed in the height direction of the mounting pole. can be fixed in any position using just the U-bolt and NAND, and the U-bolt itself can be installed at the same time as the pair of bands is fixed, so installation is easy and the pair of bands and U-bolt etc. All the necessary parts can be reliably installed on the mounting pole in one installation, and the ends of the wires need only be fastened using U-bolts, providing excellent practical effects.
