JPS63106445A - Tightening device for supporting wire - Google Patents

Abstract

PURPOSE:To effect tightening and loosening arbitrarily, by using a property of a spring. CONSTITUTION:A device used for final or tentative setting of a metal wire, a rope or the like comprises a frame having one end having a bolt inserted thereon for fixing an intermediate branch wire and the other end having a brake spring 6 and a drum 9 mounted thereon. The rotary drum 9 has a diameter larger than an inner diameter of the spring 6. In operation, an end of the branch wire is fixed to a building and the other end thereof is wound around the bolt to be fixed. Then, an end of another branch wire is fixed to another building and the other end thereof is passed through a hole 10 of the drum 9 and taken out from a slot 8. Nest, an iron bar is inserted into an inserting port 7 to rotate the drum 9 so that the branch wire is tightened.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Back type for industrial use The present invention is used for permanent or temporary installation of metal wires, robes, etc. in antennas, farms, gardening, sports, decorations, etc.

BACKGROUND OF THE INVENTION Conventionally, it has been usual to tighten by using a tightening tool having a turnbuckle or ratchet structure, or to rely on manual tightening. However, in the case of the above-mentioned turnbuckles, they can only be adjusted within a limited range, depending on their size, and in the case of ratchets, the tightening range is free, but due to its structure, it is large and
It is not suitable for thin branch lines, etc., and it also increases the weight, so depending on the work, it may be rather inconvenient to use.

In addition, when relying on manual tightening as described above, complete tightening cannot be expected and is completely unsuitable depending on the application.

C. Problems that the invention aims to solve Taking the installation of a television antenna as an example, conventional methods have been to rely on hand-tightening or to use the aforementioned turnbuckles, but hand-tightening results in poor results. It's bad, it's uneconomical in terms of time, and it seems like there's one problem too many.

Using turnbuckles would solve the problem with the finish, but considering the time required, price, etc., it is not a good idea.

Incidentally, the above-mentioned problems are bound to occur in any case, not just antenna construction.

As shown in Figures 1 and 2, the coiled spring (brake spring (6)
) and insert a rotating drum (Fig. 2 (9)) that is slightly larger than its inner diameter. (9) rotates clockwise, that is, in the direction in which the spring loosens, but it rotates counterclockwise. , that is, the spring does not rotate in the winding direction.

Applying the above principle, the branch line can be tightened by rotating (9) clockwise.

Note that by slightly pushing the end (1) of the spring clockwise, the spring becomes slack, and (9) can be rotated counterclockwise, thereby making it possible to relax the branch line.

2. Effects and Examples The method of using the present invention is to first wrap one end of the branch line around a building or fixed object [Fig. 4 (1)], and then wrap the other end around the target building, fixed object, or Pull toward the fixed object (2) and place it at any point shorter than the length to the object (see Figure 1).
3) Wrap and fix.

Next, wrap a branch line around (2) and cut the branch line to an arbitrary length (approximately 20 to 30 cm from the distance to the instrument body).

Pull out the tip of the branch line wrapped in Figure 4 (2) to Figure 2 (10) and place it in 8) (approximately 30 to 40 cm), but you can wind it around 9) about 4 to 5 times. Create slack in length.

Next, insert a screwdriver or metal rod into (7) and tighten the branch line on the side of Figure 4 (2) by rotating Figure 2 (9) in the direction of the arrow shown in Figure 4 (3). I can do it.

Incidentally, the degree of tightening of the branch line can be easily varied by the operation shown in FIG. 1 (1). (In the direction of the arrow in Figure 4 (4)) After the tightening work is completed, the second
Wrap the branch wire pulled out from figure (8) around (2) via (7). (See Figure 5) Also, when fixing the antenna mast etc. mentioned as an example in Section 5, 3 to 4 branch lines are required, and to obtain this perpendicularity, each branch line must be connected several times. It is necessary to repeatedly tighten and loosen the body.
