Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fastener that elastically connects an antenna stay to a locking attachment portion thereof.

2. Description of the Related Art In order to securely attach an antenna such as a television antenna, its support is usually tied to an appropriate location on a building or the like via an antenna stay.

However, antenna stays are usually made of a non-stretchable material such as wire, and one end of the antenna stay is fixed to the antenna support and the other end is fixed to a building etc. via fixed hardware. The antenna stay is likely to be cut due to the large force caused by the wind, etc., and it is difficult to tension each antenna stay with an average tension.Furthermore, if the antenna stay is tensioned too tightly, there are problems such as howling noise caused by the wind. Ta.

The present invention solves the above problem by elastically tensioning the antenna stay.As a stopper for elastically tensioning the antenna stay,
Two U-shaped metal fittings having outward hook portions at both ends are stacked in opposite directions, surrounded by a spring, and the spring is connected to one of the U-shaped fittings.
It is located between the hook part of the U-shaped metal piece and the hook part of the other U-shaped metal piece, and is interposed between the antenna stay and its locking attachment part, so that the antenna stay is connected to the locking attachment part. The present invention provides an antenna stay fixing fitting which is characterized in that it is elastically connected to the antenna.

Hereinafter, an embodiment of the antenna stay fixing fitting of the present invention shown in the drawings will be described.

In Fig. 1, 1 is a TV antenna fixed on the ridge of a building, 2 is a TV antenna whose one end is locked and fixed to the support of the TV antenna 1, and the other end is connected to the roof of the building via the antenna stay fitting 3 of the present invention. This is an antenna stay that is elastically fixed to a fixed hardware 4 such as a side part.

As shown in FIG. 2, the fastener 3 has a first U-shaped metal fitting 5 having outwardly directed hook portions 5', 5' at both ends, and also has outwardly directed hooks 5' at both ends. The first U-shaped metal fitting 5 mainly consists of a second U-shaped metal fitting 6 having 6′, 6′ and a spring 7.
and the second U-shaped metal fitting 6 are overlapped in opposite directions, and they are surrounded by a spring 7, and the spring 7 is connected to the hook portion 5' of the first U-shaped metal fitting 5,
5' and the hook portions 6', 6' of the other U-shaped metal fitting 6.

When the antenna stay fixing fitting 3 of the present invention configured as described above is used, for example, as shown in FIG. In addition to the antenna stay 2, the center part of which is connected to the ring part 4'' at the tip of the arm 4' through the first U-shaped metal fitting 5, and one end is fixed to the locking attachment part of the support column 1' of the antenna 1. By connecting the center part of the second U-shaped metal fitting 6 to the end, it is interposed between the antenna stay 2 and the locking attachment part 4. By interposing it in this way, the first U-shaped hook part 5' of hardware 5;
5' and hook portions 6', 6' of the second U-shaped metal fitting 6
Both sides of the spring 7 are locked, and the tension of the antenna stay 2 exerts a compressive force on the spring 7, so that the antenna stay 2 can be elastically connected to the locking attachment part 4. Furthermore, at this time, since a compressive force acts on the spring 7 in accordance with the tension of the antenna stay 2 instead of a tensile force, there is no risk of damage due to an increase in the tension of the antenna stay 2.

Note that the fixing hardware used when using the antenna stay fixing metal fitting 3 of the present invention is not limited to the one shown in the drawings, and the antenna stay fixing metal fitting 3 of the present invention can be connected to the end of the antenna stay 2. Instead of interposing it between the fixing attachment part 4 and the antenna stay 2, it can be interposed, for example, in the middle part of the antenna stay 2, or between the antenna support column 1' and the antenna stay 2.

As mentioned above, the antenna stay fixing fitting of the present invention can be interposed between the antenna stay and its locking attachment part to elastically connect the antenna stay to the locking attachment part. Therefore, it is easy to tension the antenna stay, and it is possible to prevent the antenna stay from being cut due to large external forces such as wind, and to prevent the antenna stay from generating whirring noise, and to even out the tension force of each antenna stay. The antenna can be supported, and together with its simple configuration, it has great practical effects.
