Next, a bolt 30 is loosened, the fixing tool 23 is slid, moved to a fitting surface 26 in the direction where the panel 2 approaches, the bolt 30 is tightened and fixed, and therefore, the projection allowance of the fitting surface and an antenna 1 can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mounting device for a flat antenna for receiving satellite broadcasting, which is rotatable in the horizontal and vertical directions.

[Conventional technology 1] Use of a flat antenna in place of a conventional parabolic antenna as an antenna for individual home reception of satellite broadcasting using microwaves (12Gt (7)) carried out by a geostationary satellite 36,000 above the equator. is proposed.

At present, this planar antenna uses an angle adjustment fitting 50 that can be adjusted in the horizontal and vertical directions, as shown in FIG. That is, as shown in the figure, for example, a cross section of 1. Molded metal fittings 52
Attach two pieces on top and bottom, and attach l to this metal fitting 52 with a fixing device 53.
) (One end of the J-shaped mounting 54 is attached, and the angle adjustment bracket 50 is attached to the other end so as to be rotatable in the horizontal direction to set the azimuth.The antenna panel 55 is attached to the angle adjustment bracket 54. 50, and the shaft 56 is a rotation axis, and it is rotated in the vertical direction to set the elevation angle.The azimuth angle is fixed with the bolt 57 of the angle adjustment fitting 50, and the elevation angle is fixed with a circular arc shape. This is done with a bolt 60 inserted into a hole 59 in a fixing plate 58.

[Problem to be Solved by the Invention 1] The problem with conventional mounting brackets is that satellite broadcasting exists at a constant elevation and azimuth angle with respect to a certain ground, so the directivity of a flat antenna is extremely sensitive. This means that the pointing direction must be directed directly toward the satellite. However, in most buildings, there are very few examples in which the mounting surface faces directly toward the satellite. For this reason, in conventional planar antennas, unless the mounting surface is facing toward the satellite at that point, the top side AB or bottom side CD of the antenna panel is not parallel to the mounting surface, as shown in Figure 3(a). First, there was a problem in that DE and CF were not equal in protrusion from the mounting surface at both ends of the antenna, and DE protruded considerably from the mounting surface.

The present invention has been provided in view of the above-mentioned points, and provides a planar antenna mounting device for the purpose of reducing the margin for protruding the antenna section from the mounting surface.

[Means for Solving the Problems] The present invention is provided with a rotating means that allows the antenna section to rotate on a plane perpendicular to the direction of orientation of the antenna.

[Operation 1 The antenna part is rotated on a plane perpendicular to the pointing direction of the antenna by the rotating means (Embodiment) Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1st
The figure shows an exploded perspective view of the whole, and FIG. 2 shows a side view. The antenna section 1 is composed of a flat antenna panel 2 and a substantially U-shaped metal fitting 3 attached to the back surface of the antenna panel 2 with screws 4 and washers 5. Metal fittings 3
A support 6 is protruded from the back side of the holder, and the support 6 is inserted into a through hole 9 drilled in the circumferential surface of a cylindrical support 8.
A split pin 7 is inserted at the tip of the column 6 to prevent the column 6 from coming off the support 8. A protrusion 10 that serves as a rotating shaft is protruded from the center of both side surfaces of the support %8, and this protrusion 1
0 is inserted into the hole 12 of the substantially F-shaped support fitting 11 to be rotatable. The support 8 connects the flat plate 13 with a washer 14,
The support 8 is fixed to the upper surface of the support 11 with a spring 15 and a screw 16 to prevent it from coming off from the support 11.

The rotation of the support 8 and the support metal 11 is fixed by using a screwdriver 17.
and one bolt via the spring 18 to the support fitting 11.
Insert the arc-shaped hole 20 on the side of the support 8 into the hole 2 on the side of the support 8.
This is done by screwing on 1. A post 22 is hung vertically from the bottom surface of the support fitting 11, and this post 22 is inserted into a hole 24 that passes through the top and bottom of the end of a rectangular fixture 23, and a split pin 25 is inserted into the tip of the post 22. So, the removal is stopped. The support 27 connected to the mounting base 26 has an elongated hole 28 formed in its side surface, and has a box shape with one side open so that the fixture 23 can slide inside. The support 27 and the fixture 23 include a bolt 30 passed through the long hole 28 in the screw hole 29, and a spring 31.
, and are fixed by washers 32. The antenna is mounted via the mounting base 26 with bolts or the like.

To adjust the azimuth angle of the antenna, the antenna is inserted into the hole 24 of the fixture 23 using the support 22 as a rotation axis so that it can rotate freely in the horizontal direction, and the azimuth angle is adjusted. This shaft is fixed by passing a washer 34, a spring 35, and a bolt 36 through the screw hole 33 that penetrates to the hole 24, and then attaching the support 22 to the bolt 3.
Press 6 to secure. Next, adjust the elevation angle as follows. That is, one bolt is loosened, and the support 8 is inserted into the arc-shaped hole 20 centered on the protrusion 10.
That is, the elevation angle of the antenna panel 2 is adjusted by making the support 6 inserted into the support 8 rotatable in the vertical direction. After adjustment, tighten bolt 19 to fix.

Next, a description will be given of a rotating means that allows the antenna section 1 to rotate on a plane perpendicular to the direction of antenna orientation. Adjusting the rotation on the plane perpendicular to the antenna's pointing direction is
The bolts 39 are loosened, and the support column 6 serving as a rotating ring is adjusted to be rotatable. After adjustment, the bolts 39 are screwed into the screw holes 37, and the tips of the three bolts are pushed to the support column 6 and fixed. Incidentally, the above-mentioned rotating means is constituted by the support 8, the column 6, the bolt 39, and the like.

The method of actually adjusting the antenna is to adjust the azimuth angle and the elevation angle, as shown in FIG. 3(,). The person rotates the antenna panel 2 around the pointing direction to a position where the upper side AB and the lower side CD become parallel to the mounting surface 38. This is done by loosening the bolt 19.

Once line 117 is aligned with the mounting surface 38, tighten the bolt 19 to fix it. Next, as shown in Figure 3 (1)), loosen the bolt 30, slide the fixing bar 23, and remove it.
By moving the antenna panel 2 in the direction 98 and tightening the bolt 30, the installation of the satellite broadcast receiving flat antenna is completed. Therefore, as shown in FIG. 3(C), the distances between CF' and DE' can be made equal and the margin can be made as small as possible.

[Effects of the Invention 1] As described above, the present invention is provided with a rotating means that allows the antenna section to rotate in a plane perpendicular to the pointing direction of the antenna. By rotating the antenna in a plane perpendicular to the direction of antenna orientation, and making the top and bottom sides of the antenna part parallel to the mounting surface, the antenna The antenna can be installed with as little extension of the antenna as possible, and therefore the characteristics of the flat antenna, which has a good appearance, can be utilized, and the antenna is less susceptible to wind effects.
