Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antenna mounting mechanism, and it is an object of the present invention to provide a mechanism capable of stably and accurately mounting a satellite dish such as a satellite dish for receiving satellite broadcasting under various conditions. Is.

[0002]

2. Description of the Related Art Various mechanisms for mounting a parabolic antenna at a high place have been announced and put into practical use. For example, it is common to attach an antenna body by using an angle adjusting metal fitting or the like at the tip of a mounting metal fitting whose base end is fixed to a fixing metal fitting.

In contrast to the conventional one as described above, in Japanese Patent Laid-Open No. 2-60306, in an antenna which can be rotated in the horizontal direction and the vertical direction, the antenna part is rotated on a plane perpendicular to the direction of the antenna. An attachment device has been announced, which is characterized in that it is provided with a rotating means for making it movable.

In Japanese Utility Model Laid-Open No. 4-91404, the mounting base has an L-shaped cross section, a J-shaped pole is connected to the mounting base, and the short portion of the pole is inserted into the U-shaped groove of the mounting base. It has been proposed to bolt.

[0005]

In the above-mentioned conventional general type, when receiving satellite broadcasting, there is a constant elevation angle and azimuth angle at each point, and the directivity direction of the antenna whose directivity is sensitive is accurate. It is difficult to obtain, and the antenna and the mounting base body are cylindrical, prismatic,
It is not easy to quickly respond to changes in the shape of the fence or other shapes.

In the above-mentioned Japanese Patent Application Laid-Open No. 2-60306, the antenna part is rotated on a plane perpendicular to the direction of the antenna so that the upper side and the lower side of the antenna part are parallel to the mounting surface. Regardless of the orientation of the mounting surface of the antenna, even if it has the advantage that it can be mounted with the antenna's margin being as small as possible, it can respond quickly to changes in the configuration of the mounting base body and other fluctuation conditions. The difficult disadvantage still remains.

Even in the case of the actual Kaihei 4-91404, J
Even if the pole bent in a letter shape can be properly attached, it cannot respond promptly to changes in the configuration and shape of the attachment base body, and there is a drawback that the attachment conditions for the antenna are also limited.
