Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a satellite antenna device for receiving a signal from a broadcasting satellite or a communication satellite in a geostationary orbit, and more particularly to a satellite antenna device which can be easily installed on a veranda.

[0002]

2. Description of the Related Art In recent years, satellite broadcasting by a broadcasting satellite (hereinafter referred to as "BS") has started in earnest, so that the number of households having a receiving system for BS is increasing. This BS
The receiving system for BS consists of a BS antenna and a BS tuner. And the BS antenna is
Generally, a reflector having a parabolic surface, a feed horn that receives a signal of a radio wave reflected by the reflector and focused on a focus, and the frequency of the radio wave taken in the feed horn are input to the BS tuner. It is composed of an LNB (hereinafter referred to as an LNB) that is output down to the frequency and is of a type called a parabolic reflector.

Conventionally, since the BS antenna has a large elevation angle with respect to the satellite, it can be mounted on a pillar of a handrail of a veranda, which is relatively easy to mount, unless a building adjacent to the satellite is too high. Many. When the BS antenna is attached to the column, the BS antenna is attached to the round bar pole in advance so that the elevation angle can be changed.
This pole is attached to the handrail pillar of the veranda by the mounting hardware. Next, the elevation angle of the BS antenna was adjusted and the direction was adjusted by rotating the pole.

[0004]

By the way, the shape of the pillar of the handrail of the veranda may be a cylindrical shape, a square tube shape, a thin plate shape, or the like. , Different ones are prepared. Therefore,
When mounting the BS antenna, it is necessary to check the shape and thickness of the support in advance and then prepare the mounting bracket, which makes the mounting work of the BS antenna troublesome. In particular, when a viewer of a BS broadcast does the work of mounting the antenna by himself, it is often the case that he purchases the wrong mounting bracket when he purchases the antenna and must replace the mounting bracket. ..

Further, even when the mounting bracket is attached to the handrail, the handrail may have a cylindrical shape or a square tube shape and has a different thickness. The mounting hardware must be selected according to the shape of the slide. Also, when making fine adjustments to the antenna direction, it is necessary to check the TV screen by the antenna level display function built into the BS tuner, and one person can check the antenna level in front of the TV and One person had to adjust the direction of the antenna, which was a troublesome task.

The present invention has been proposed in view of the above circumstances, and an object of the present invention is that it can be easily mounted regardless of the shape of the support pillar of the handrail of the veranda, and the direction of the antenna can be easily adjusted. It is to provide a satellite antenna device that can be finely adjusted.

[0007]

A satellite antenna device of the present invention comprises an antenna section for receiving radio waves from the satellite,
A rotating device that horizontally rotates a rotating shaft that supports the antenna part, a base part that supports the rotating device so as to be vertically rotatable, and an attaching part that attaches the base part to a veranda. In addition, it is for receiving radio waves from a broadcasting satellite or a communication satellite revolving in a geostationary orbit, and the base part is a rectangular plate-shaped bottom plate and stands upright on the left and right sides of the bottom plate. And a side plate for fixing the rotating device by deciding an elevation angle of the antenna part, wherein the mounting part is provided between a rear end part of the side plate and a back plate provided vertically. A plate-shaped holding plate that is arranged in parallel with the back plate and holds the handrail of the veranda together with the back plate; a first hooking piece that extends rearward from the back plate; Extends at a position facing the first hooking piece so as to face the first hooking piece A second hooking piece, and a flange piece for connecting the first and second hooking pieces to each other is provided upright at the tips of the first and second hooking pieces. The flange pieces are fastened together by bolts, and the back plate and the sandwiching plate sandwiching the handrail are fastened together by bolts.

[0008]

According to the above construction, when the BS antenna is attached to the handrail of the veranda, the handrail is sandwiched between the back plate and the sandwiching plate, and the handrail is secured by the first and second retaining pieces. It can be fixed by fastening the flange pieces to each other and the holding plate and the back plate with bolts while the upper surface is hooked. At this time, since the antenna unit can be rotated by the rotating device, the direction of the antenna unit does not matter.

Even if the handrail has a different shape such as a cylindrical shape or a rectangular tube shape or has a different thickness, the first and second hooking pieces are provided on the upper surface of the handrail. Hung up,
Since the handrail is sandwiched between the holding plate and the back plate, the handrail is sandwiched between the holding plate and the back plate, and by tightening with bolts, it can be easily attached regardless of the width of the handrail. be able to. Further, since the mounting portion holds the handrail, it is not necessary to use different mounting fittings depending on the shape of the support.

Further, as described above, since the antenna unit can be rotated by the rotating device, remote control becomes possible, and by using the remote control, the antenna unit can be seen while watching the antenna level displayed on the tuner. The direction of can be easily fine-tuned.
