Description

[Detailed Description of the Invention] The present invention relates to a simple mounting bracket for a satellite receiving antenna used when receiving broadcast radio waves emitted from a geostationary satellite or the like using a receiver installed in each home.

Although we have not yet reached the stage where households can receive broadcast waves from satellites, it is predicted that such an era will come in the near future. In this case, it is necessary to install a satellite receiving antenna on a structure such as the roof of each home, but unlike the case of receiving TV waves from a conventional terrestrial transmitting antenna, in the case of satellite reception, the receiving antenna is placed precisely in the direction of the geostationary satellite. A mechanism that allows easy adjustment of the horizontal azimuth angle and vertical elevation angle is desired.

Therefore, a support structure, ie, a mounting bracket, as shown in FIG. 1 is generally considered. In Fig. 1, 1 is a satellite receiving antenna, 2 is a pipe, 3 is a clamp, 4 and 5 are fittings for fixing to the outside wall, 6 is an elevation adjustment section, 7 is an outside wall, and 2 to 6 are collectively called the mounting fittings, clamps. The horizontal direction can be adjusted by loosening 3 and turning it around the pipe 2, and the elevation angle of the antenna can be adjusted by extending or contracting the elevation adjustment part.

Such a mounting bracket has the disadvantage that the adjustment of the azimuth angle and the angle of elevation are performed using separate brackets, which requires a lot of effort. Also, the number of parts is large, which is not compatible with the desire to lower the price for household use.

The present invention eliminates the drawbacks of the conventional examples and provides a mounting bracket that has a simple structure and is easy to adjust.It is bent into a U-shape in a horizontal plane so that the end can be attached to the outer wall of a house, etc. It consists of a metal pipe or round metal bar with a mounting part, a base metal fitting for fixing the satellite receiving antenna, and a tightening metal fitting.
By sandwiching the metal pipe or round bar between the base metal fitting and the clamping metal fitting, and loosening the tightening of the clamping metal fitting, the base metal fitting and the clamping metal fitting can be slid along the pipe or round bar, and the pipe or round bar can be slid along the pipe or round bar. It is characterized in that it is rotated in the circumferential direction.

The following will be explained based on examples.

Figure 2 A and B are examples of the present invention; A is a side view;
B shows a bottom view, the satellite receiving antenna 1 is fixed to the base metal fitting 11, and the base metal fitting 11 and the tightening metal fitting 1
2 is fixed so as to cover a metal pipe or round bar 13. In the figure, fixation is done using bolts and nuts, but it is not limited to bolts and nuts as long as they can be easily tightened or loosened. The metal pipe or round bar 13 is bent into a U-shape in one plane, and the end of the pipe or round bar is fixed to the outer wall 14 or the like of the house with nails 15 or the like.

Note that this fixing to the outer wall etc. is not limited to fixing with nails, but may also be done by flange attachment. Furthermore, if the fixing point is a handrail made of metal pipe, it is also possible to fix it with U bolts or the like. The metal pipe or round bar is bent into a U-shape in a horizontal plane as shown in FIG. 2, and the mounting portion is bent appropriately depending on the shape of the wall.

By loosening the fastening of the base metal fitting 11 and the fastening metal fitting 12, the satellite receiving antenna can be rotated around the metal pipe or round bar 13 while being fixed to the base metal fitting, or it can be slid along the metal pipe or round bar 13. The elevation and direction angles can be adjusted at the same time. In the figure, the U-shape is bent in the horizontal plane, with an elevation angle of θ and an azimuth angle of θ.

In addition, the satellite receiving antenna 1 and base metal fitting 11 in Fig. 2
If it is fixed with a screw 16, the elevation angle can be finely adjusted by adjusting the screw 16.

As mentioned above, the mounting bracket for the satellite receiving antenna of the present invention is such that the base bracket and the clamping bracket can be slid and rotated along a metal pipe or round bar bent into a U-shape in a horizontal or vertical plane. This has the advantage that the azimuth and elevation of the satellite receiving antenna fixed to the base metal fitting can be adjusted at the same time by loosening the tightening metal fitting.
Further, there is no need to manufacture the adjustment fittings individually as in the conventional example, and only one is required, so the number of parts can be reduced.
