Description

TECHNICAL FIELD The present invention relates to a planar antenna mounting device for receiving satellite broadcasts.

[Background Art] It has been proposed to use a flat antenna instead of a conventional parabolic antenna as an antenna for individually receiving satellite broadcasting using microwaves (12 GHz) performed by a geostationary satellite 36000 km above the equator at home. At present, this planar antenna 1 is attached to the wall surface of a building as shown in FIG. The mounting structure of the planar antenna 1 is such that the antenna panel 4 is fixed to the metal mounting base 2 tightly bonded to the mounting wall surface via the angle adjusting metal fitting 3 as shown in FIG. However, the problem here is that satellite broadcasting exists at a certain elevation angle and azimuth angle with respect to a certain point (for example, in the Osaka area ...
(About 41 °, azimuth angle ... about 220 °), and therefore, in the case of the plane antenna 1 having extremely sharp directivity, it is necessary to direct the direction of the plane antenna 1 straight to the satellite direction.
In most buildings (particularly single-family dwelling units), there are very few cases where the wall faces straight toward the satellite. For this reason, the conventional planar antenna 1 is provided with the clearance X as shown in the drawing so that the elevation angle and azimuth angle of the planar antenna 1 can be adjusted after being tightly bound to the wall surface.

However, because this clearance X is designed on the assumption that it will be attached to the wall surface of the building with the worst conditions in design (wall surface facing the elevation angle of about 175 ° or 265 ° in the Osaka area), it is relatively in the direction of the satellite. When it was attached to a wall surface facing straight, the clearance X was changed to the protrusion of the antenna panel 4 and was a significant negative factor in appearance.

FIG. 7 (a) shows the concept of mounting the planar antenna 1 in the case where the respective wall surfaces face relatively north, south, east, and west,
It can be seen that the clearance X is necessary to adjust the angle of the antenna panel 4 in the direction of the satellite 5. FIG. 7 (b) shows the concept when the planar antenna 1 is attached to a building having a wall surface that is relatively straight in the satellite direction. In this case, the antenna panel 4 separates from the wall surface, which is not very desirable in appearance. I understand.

[Object of the Invention] The present invention has been made in view of the above-described problems, and an object of the present invention is to attach a plane antenna for satellite broadcast reception to a wall surface of a building in any orientation with good compatibility. It is possible to provide a flat antenna mounting device for receiving satellite broadcasting.

DISCLOSURE OF THE INVENTION The present invention is capable of rotating horizontally and vertically with respect to one leg of a supporting member having a substantially U-shaped antenna part of a planar antenna for receiving satellite broadcasting. It is characterized in that the other leg of the support is pivotally mounted so as to be rotatable in the horizontal direction with respect to a mounting base fixed to a mounting wall surface.

The present invention will be described below with reference to examples.

Embodiment FIG. 1 to FIG. 4 show this embodiment, in which an antenna panel 4 is fixed to a mounting base 2'which is tightly connected to an anchor bolt attached to a flat antenna mounting wall surface via a support 6. The support 6 is made of a pipe bent in a U shape, and is connected to the mounting base 2 ′ by a bending plate 7 whose cross section is bent downward in a U shape and a U-shaped bolt 8. That is, one leg of the support 6 is held by the bending plate 7 along the concave portion of the bending plate 7, and the leg of the support 6 is pressed down by the U-shaped bolt 8 to the bending plate 7. The tip of the V-shaped bolt 8 is passed through the bending plate 7, and the pillow metal fitting 9 is provided outside the bending plate 7.
The nut 10, the spring 11, and the washer 12 are screwed and fixed. The bending plate 7 is fixed on both side pieces to the fixing pieces 5 and 5 standing in parallel on the surface of the mounting base 2'by screws 19, nuts 17, and spring washers 16. The antenna panel 4 has an antenna fixing bar 20 screw-fixed on the rear surface thereof,
The storage box 14 is fixed to form an antenna section. Similar to the connection between the mounting base 2'and the support 6, the connection between the antenna portion and the support 6 is a bending plate 7'having a U-shaped cross section, a U-shaped bolt 8 ', and a pillow fitting. 9 ', a nut 10', a spring 11 'and a washer 12'. Reference numeral 18 is a cap that fits into both openings of the support 6.

Here, the bending plate 7'is provided with bolt holes 13 and
The bolts 15 and 15 'are inserted from the side surface of the LNB storage box 14 into 3', and fastened and fixed by nuts 21 and 21 '.

In the LNB storage box 14, as shown in FIG. 3, an antenna circuit section 17 fixed to the back surface of the antenna panel 4 is stored.

Therefore, when adjusting the azimuth angle of the planar antenna, U
The fastening of the V-shaped bolt 8'is loosened so that the antenna part can be rotated in the horizontal direction with respect to the support 6, and the antenna panel 4
Adjust the azimuth angle of. After this adjustment, a U-shaped bolt 8'is fastened, and by this fastening, the support 6 held by the bending plate 7 is held.
The leg pieces of are fixed and the azimuth of the antenna panel 4 is fixed.

Next, when adjusting the elevation angle of the antenna panel 4,
Loosen the fastening of the bolts 15 and 15 'so that the bolt 15' can move in the arcuate bolt hole 13 'centering on the upper bolt hole 13, that is, the bending plate 7'to the LNB storage box 14 in the vertical direction. The elevation angle is adjusted to be freely rotatable. After this adjustment, the bolts 15 and 15 'are fastened to fix the inclination of the bending plate 7'with respect to the LNB storage box 14, that is, the elevation angle of the antenna panel 4.

After adjusting and fixing the azimuth and elevation in this way, U
By loosening the fastening condition of the V-shaped bolt 8, the supporting tool 6 is made rotatable in the horizontal direction with respect to the mounting base 2 '.
As shown by the broken line in the figure, when the antenna portion is brought as close to the mounting wall surface Y as possible and the U-shaped bolt 8 is fastened and fixed, the mounting of the satellite broadcast receiving flat antenna is completed.

[Advantages of the Invention] The present invention makes it possible to rotate horizontally and vertically with respect to one leg of a support tool in which the antenna portion of a satellite broadcast receiving planar antenna is formed in a substantially U shape. Since the other leg of the support is pivotally pivoted horizontally with respect to the mounting base fixed to the mounting wall surface, the antenna part is as close to the mounting wall surface as possible regardless of the mounting wall direction. It can be installed by making it possible to match well with the difference in the structure of the building, and it is possible to take advantage of the features of the planar antenna that looks better than the parabolic antenna, and the structure is simple. Play.
