[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a mounting device such as a flat antenna used for satellite broadcasting reception.

[0002]

[Prior Art]

 The conventional planar antenna is generally mounted by a mounting device as shown in FIG. That is, in the mounting device shown in FIG. 5, the mounting auxiliary tool 23 paired with the mounting tool 23 is replaced with a bolt. In addition to fixing it with 12 l, a prismatic column connecting member 22 is fixed to the fitting 23 with bolts and nuts 12k, and a tubular supporting column 21 is fixed to the supporting member 22 with bolts and nuts 12j. A strut fixture 20 having a strut mounting cylinder portion 19 and an elevation angle adjusting portion 13 is pressed and fixed to the tip of the strut 21 by a bolt and nut 12m, and a guide is attached to the tip end portion of the strut fixture 20. A bolt / nut 12b, which also serves as a doublet, is attached. Further, an antenna fixing tool 4 having an antenna fixing part 2 and an elevation angle adjusting part 3 is rotatably attached to the tip of the column fixing tool 20 through a bolt nut 12a. Antenna 1 is installed.

Therefore, according to the above device, the entire device can be fixed to the fixture 23 through the tubular support 21, so that the shape of the fixture can be variously changed if the diameter of the support mounting cylinder portion 19 is the same. Although it can be done, it has the following problems. (1) Since the tubular strut 21 is interposed, the strut fixing tool 20 and the strut connecting tool 22 are required, resulting in a large number of parts and a high cost. (2) Since many parts are fixed to each other, many bolts and nuts are required to assemble and process. (3) Since the structure is such that the support fixture 20 is simply fixed to the support 21, there is no reference when adjusting the azimuth, and fine adjustment is difficult.

To solve the above problems, the applicant has previously proposed an antenna mounting device as shown in FIGS. 3 and 4. This device has an antenna fixing tool 4 having the same structure as that of FIG. 5, a connecting tool 15 including an elevation angle adjusting unit 13 and an orientation angle adjusting unit 14, and an attaching tool 18 including an azimuth angle adjusting unit 16 and an attaching unit 17. Composed of.

In the above case, the antenna fixing tool 4 is attached to the elevation angle adjusting portion 13 of the connecting tool 15 with bolts and nuts 12a and 12b as in the case of FIG. A fixing hole (reference numeral omitted) and a guide hole 14a are attached to the azimuth angle adjusting portion 16 of the portion 14 and the attachment 18 by using bolts and nuts 12g and 12h with 12g as a rotation axis.

[0006]

[Problems to be solved by the device]

 Comparing the case of the mounting device of FIGS. 3 and 4 with the case of the mounting device of FIG. 5, the number of parts and the number of bolts and nuts connecting them are small in the case of the mounting device of FIGS. , It is very economical because both the assembly cost can be reduced, but the fixing holes are arranged so that the center line of the azimuth angle adjustment range has an inclination angle with respect to the horizontal direction of the vertical surface of the mounting portion 17 to the wall surface. Therefore, the azimuth adjustment range is still small even if the mounting tool 18 is inverted, and therefore the antenna 1 cannot be adjusted substantially vertically to the wall surface, that is, the antenna position cannot be adjusted to a range substantially parallel to the wall surface. There were challenges.

[0007]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, and an antenna fixing tool having an antenna fixing part for fixing the rear surface of the antenna and an elevation angle adjusting part for adjusting the elevation angle of the antenna, an elevation adjusting part and an azimuth of the antenna. A connector having an azimuth angle adjusting section for adjusting the angle, an elevation adjusting means for adjusting the elevation angle by connecting the antenna fixing tool and the fixing holes provided in each elevation adjusting section of the connecting tool, and the azimuth adjusting section. An arm tool that is provided, a mounting tool that is fixed to the arm tool for mounting the arm tool on a wall surface, a fixing hole that is provided in each azimuth angle adjusting portion of the connecting tool and the arm tool, and a spacing from a central fixing hole. And an azimuth angle adjusting means for adjusting the azimuth angle by connecting guide holes that are attached to the fixture and have one end in a substantially vertical direction and the other end in a substantially parallel direction. It is a thing.

FIG. 1a is a side view of the antenna 1 mounted on a handrail or the like by the antenna mounting device of the present invention. The back surface of the antenna 1 is fixed to an antenna fixing portion 2 of an antenna fixing tool 4 (a U-shaped cross-section and a projecting piece is symmetrical although a plan view is omitted), and the antenna fixing tool shown in FIG. 4 is provided with a fixing hole 3a of the elevation angle adjusting unit 3 and a guide hole 3 (b) which is an adjustment range of the elevation angle, and fixing holes 5a and 5b are provided in the elevation angle adjusting unit 5 of the connector 7 shown in FIG. 1 (c). ing.

Therefore, one side of the connector 7 is inserted between the antenna fixtures 4, bolts and nuts 12a are inserted into the fixing holes 3a and 5a, and the antenna fixture 4 is connected by the bolts and nuts 12a. 7 is rotatably supported, and bolts and nuts 12b are inserted into the fixing holes 5b and the guide holes 3b. The antenna fixture 4 is rotated at a predetermined angle with the bolt / nut 12a as a fulcrum to adjust the elevation angle of the antenna 1, and after the positioning adjustment, the bolt / nut 12b is tightened to bring the antenna fixture 4 to the predetermined elevation angle. Fix it. Note that, conversely to the above, it is possible to dispose two fixing holes in the elevation angle adjusting section 3 of the antenna fixing tool 4 and to arrange a fixing hole and a guide hole in the elevation angle adjusting section 5 of the connecting tool 7.

Further, as shown in FIG. 1D, fixing holes 6a and 6b substantially parallel to the surface of the antenna 1 are provided in each of the upper and lower azimuth angle adjusting portions 6 of the connector 7, and further, FIG. (F) (g) The upper and lower azimuth angle adjusting portions 8 of the arm member 9 are provided with a fixing hole 8a and a space around the fixing hole 8a. A guide hole 8b having one end substantially perpendicular to the fixture 10 and the other end substantially parallel to the fixture 10 fixed at 12e and shown in FIGS.

Therefore, one side of the connecting tool 7 is inserted inside the arm tool 9, bolts and nuts 12c are inserted into the fixing holes 6b and 8a, and bolts and nuts 12d are inserted into the fixing holes 6a and the guide holes 8b. The connector 7 is inserted and rotated with the bolt / nut 12c as a fulcrum to adjust the azimuth of the antenna 1, and after the positioning adjustment, the bolt / nut 12d is tightened to fix the connector 7 at a predetermined azimuth. Note that, conversely to the above, it is possible to dispose the fixing hole and the guide hole in the azimuth angle adjusting portion 6 of the connecting tool 7 and the two fixing holes in the azimuth angle adjusting portion of the arm tool 9.

FIGS. 2A and 2B are plan views of the antenna mounting device in which the arm member 9 is inverted and mounted on a wall surface or the like (not shown) via the mounting member 10. That is, FIG. 2A shows the case where the connecting tool 7 has an azimuth angle orthogonal to one side of the arm tool 9, and the antenna 1 is perpendicular to the wall surface or the like on which the mounting tool 10 is mounted. Further, FIG. 2B shows a case where the connecting tool 7 has an azimuth angle orthogonal to the opposite side of the arm tool, and the antenna 1 is perpendicular to the wall surface or the like as described above.

As described above, according to the present device, the azimuth angle can be adjusted in a wide range of approximately 180 degrees parallel to the mounting tool 10, that is, the wall surface by reversing the arm tool 9.

Further, in the present device, if an attachment assisting tool 11 shown in FIGS. 1 (j) and 1 (k) which is paired with the attaching tool 10 is used, a handrail such as a veranda, a lattice, etc. can be engaged with a bolt / nut 12 (f). It can be installed by stopping and inserting. It should be noted that the fixture 10 has a rectangular shape as a whole, so that it can handle handrails, grids, and the like.

Further, since the vicinity of the guide hole 8b of the azimuth angle adjusting portion 8 of the arm member 9 is flat, it is possible to provide a scale as a guide for the angle. Further, the arm tool 9 and the mounting tool 10 may be integrated.

Reference numeral 24 is a converter attached to the back surface of the antenna 1.

[Effect of the device]

 According to the present invention, the elevation angle can be adjusted between the antenna fixing tool and the coupling tool, and the azimuth angle can be adjusted between the coupling tool and the arm tool. Since the number of bolts and nuts for fixing the above components to each other is also small, both material cost and manufacturing cost are reduced. In particular, the azimuth angle adjustment range is wide and it is possible to adjust the azimuth within a range substantially parallel to the mounting wall surface by reversing the arm tool.There are also few restrictions on the mounting location, and fine adjustment of the azimuth angle is easy. As a result, the function as an antenna mounting device can be improved.
