Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antenna device mounting tool for installing the antenna device on a handrail of a veranda while being fixed to a mast.

[0002]

2. Description of the Related Art FIG. 4 is an overall explanatory view of an installation state of an antenna using a conventional antenna device mounting tool. As shown in FIG. 4, the antenna device for satellite broadcast reception is
For example, it is installed on the handrail of a veranda or the like by using an antenna device mounting tool. Reference numeral 1 is a parabolic reflector that reflects satellite broadcast radio waves so as to concentrate them on a focal point. Reference numeral 2 is a converter that amplifies a weak satellite broadcast wave with low noise and converts it into an intermediate frequency. Reference numeral 3 is a support arm that fixes the converter at the focal position. Reference numeral 4 is a mast that supports the parabolic reflector 1 at the tip and attaches the base end to the handrail of the veranda and the like. Reference numeral 5 denotes a mast fitting for fixing the parabolic reflector 1 to the mast so that the parabolic reflector 1 has a predetermined azimuth and elevation. Reference numeral 6 denotes a pair of plates, one of which is fixed to the base end of the mast 4 and the other of which is opposed to the mast 4 with the handrail of the veranda and the like sandwiched therebetween. 7 is a balcony railing. Reference numeral 8 is a coaxial cable that electrically connects the converter 2 and a tuner (not shown) in the room. 9 is a so-called, such as vinyl tape or tie wrap for fixing the coaxial cable,
It is a clamper.

The parabolic reflector with the converter 2 attached to the focal position via the support arm 3 is a handrail 7 of the veranda.
The mast fitting 5 is adjusted and fixed to the mast 4 attached to the mast 4 through the plate 6 so as to face the predetermined direction.

By the way, the coaxial cable 8 is, for example, an S-5C-FB type cable, has an outer diameter of about 8 mm and is slightly hard and difficult to bend. Arrange along a gentle curved line,
It was fixed at each required position with a clamper 9 so that it would not shake even in strong winds, and was installed so that the intermediate frequency signal of satellite broadcasting could be transmitted stably.

However, since the coaxial cable 8 is installed so that it can be seen from the outside, it is not preferable in terms of appearance, and there is a problem that the cable and the connector joint are deteriorated by rocking due to wind or the like.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide an antenna device mounting tool which is excellent in appearance, low in cost, and simple in work.

[0007]

In order to achieve the above object, an antenna device in which a converter is installed at a focal position of a parabolic reflector via a support arm fixed to the parabolic reflector and the antenna device at a required angle A mast fitting for fixing the antenna device, a mast for supporting the antenna device, and a plate for mounting the base end of the mast to a support, wherein the mast is hollow and A coaxial cable insertion hole is provided at a required position of the mast.

[0008]

With the above-mentioned structure, the coaxial cable for electrically connecting to the converter is wired outside along the support arm, and is also wired inside the hollow mast through the insertion hole to form the plate. Since the wires are laid out to the outside again, the middle part is stored in the mast.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An antenna device mounting tool according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is an overall explanatory view of an installation state of an antenna using an antenna device mounting tool according to the present invention. The same functional parts as those in the conventional example shown in FIG. Reference numeral 10 is an insertion hole for the coaxial cable 8 provided in the lower part of the L-shaped hollow mast 4.

A wiring state of a coaxial cable using the antenna device mounting tool according to the present invention will be described with reference to FIGS. 1 and 2.
FIG. 2 is an enlarged perspective view of a main part of the antenna device attachment according to the present invention. A coaxial cable 8 for electrically connecting to the converter 2 and transmitting an intermediate frequency signal of satellite broadcasting is laid in a gentle curved shape along the support arm 3, and a required portion is fixed (clamped). ), And then
Insertion hole 10 provided at the bottom of the L-shaped hollow mast 4
Via the inside of the hollow mast 4, the mast base opening 12 connected to one of the plates 6 again exits to the outside, passes between the lattices of the handrail 7, and penetrates through the other plate 6. It is routed via 11 to reach the inside of the balcony.

The insertion hole 10 is provided at the lower end of the L-shaped hollow mast 4 to prevent rainwater from entering. Further, the mast 4 is not limited to the L shape,
For example, it may be linear, in which case the insertion hole 10
Is provided at a position (intermediate part) near the support arm 3 of the mast 4 so that the cable length is shortest and almost straight. The coaxial cable 8 is again output from the mast base opening 12 at the lower end of the mast 4 to the veranda. Wire to reach inside.

FIG. 3 is an external view including a partial cross-sectional view of a seal member used together with the antenna device attachment according to the present invention. By fitting a sealing member 13 made of an elastic material such as rubber or silicon rubber into the insertion hole 10, the rainwater is prevented from entering the mast 4 and the coaxial cable 8 is further fixed. The structure of the seal member 13 will be described in detail with reference to FIG. The seal member 13 has a substantially cylindrical shape having a taper 16 from the front end to the center and an insertion hole 14 for allowing the coaxial cable 8 to pass therethrough, and the end of the taper 16 has a ring around the cylindrical shape. The groove 15 is provided. Therefore, when the seal member 13 in which the coaxial cable 8 is fitted in the insertion hole 14 is press-fitted into the insertion hole 10 of the mast 4 in advance, the taper 16 fits loosely, and then the ring groove 15 is fitted in the insertion hole 10. Since it matches, it is possible to prevent rainwater from entering. Further, the seal member 13 may be easily attached to the coaxial cable 8 by providing a cut 17 in the cylinder (insertion) direction of the seal member 13.

[0013]

As described above, the present invention provides an antenna device mounting tool which is excellent in appearance, low in cost, and simple in work. Therefore, there is an advantage that the wiring can be arranged so as not to shake even in a strong wind, and the coaxial cable is housed in the mast so that the appearance is refreshed. Further, since the number of fixing points using the clamper is reduced, it is possible to reduce the cost of parts and work.
