Description

[Detailed Description of the Invention] This invention relates to a horizontal and vertical antenna mounting fixture.

Television radio waves are received by placing antennas either horizontally or vertically, depending on the receiving area.

For this reason, with conventional antenna mounting tools, a horizontal mounting hole and a vertical mounting hole are drilled in the antenna arm, and the mounting hole is used depending on the receiving area to be used, and the U-bolt, nut, etc. It is fastened.

For example, if the antenna is assembled for horizontal polarization reception, when it is used in a vertical polarization reception area, the U-bolt etc. must be removed, re-inserted into the vertical mounting hole, and tightened with a nut.

If this is done, not only will it take a long time to assemble the antenna, but there is a risk that parts such as bolts and nuts may be lost.

Therefore, this invention was made with the aim of solving the above-mentioned problems, and was designed to prevent the antenna from separating from the mounting bracket, and to facilitate horizontal and vertical mounting operations. It is.

Hereinafter, this invention will be described in detail based on specific embodiments shown in the accompanying drawings.

First, the embodiments shown in FIGS. 1, 2, 3, and 4 will be described.

A mast support member 3 having a pressing recess 2 on the inner surface and a pressing member 5 having a recess 4 on the inner surface are arranged on the outer peripheral surface of the mast 1.

On the other hand, the antenna support member 6 has a U-shaped cross section that is bent upward from both ends of the base surface 7 to form an upright surface 8 and an upright surface 9.

The upright surface 8 and the base surface 7, and the upright surface 9 and the base surface 7 are bent at right angles.

Elongated holes 10, 10 spanning the upright surface 9 and the base surface 7 bent at right angles thereto are bored near both side surfaces.

Therefore, the long holes 10, 10 are bored at right angles.

In addition, an insertion hole 13 for the tip 12 of the U-shaped bolt 11 is bored near one side of the upright surface 3, and the tip of the other tip 14 of the U-shaped bolt 11 is inserted into the insertion hole 13 near the other side. Part 1
2 is inserted and an angle adjustment arcuate elongated hole 15 is bored to allow rotation around this hole.

In order to increase the strength of the antenna support member 6, outer ribs 16 and inner ribs 17 are provided.

By the way, this antenna support member 6 has an opening facing upward and an upright surface 8 in contact with the outer surface of the mast support member 3.
The base 18 of the U-shaped bolt 11 is engaged with the upright surface 8, the tip 12 of the U-shaped bolt 11 is inserted into the insertion hole 13, and the other tip 14 of the U-shaped bolt 11 is inserted into the arc-shaped elongated hole 15. death,
The mast supporting member 3 and the pressing member 5 are inserted into the image leading ends 12 and 14 so as to pass through both sides of the mast 1, and butterfly nuts 19 and 19 are screwed onto the leading ends and tightened to secure them.

Furthermore, the base 24 of the square bolt 23 is engaged with the antenna arm 21 into which a large number of antenna elements 20 are inserted and fixed, through the arc-shaped abutment 22 that reinforces the antenna arm 21. .25 is passed through the antenna arm 21.

This antenna arm 21 is placed on the antenna support member 6, and the image front end portions 25.25 are inserted into the elongated holes 10, 10, and the wing nuts 26.26 are screwed onto the ends and are tightened and fixed.

The operating mode of this fixture will be explained.

In the state shown in FIGS. 1, 2, and 3, the mast 1 has the mast support member 3 and the pressing member 5 attached to the U-shaped bolt 11.
The antenna element 20 is arranged horizontally for horizontally polarized wave reception.

To change this for vertical polarization reception, first loosen the wing nuts 26, 26.

Loosen the wing nut 26.26 enough so that it does not fall off from the tip 25.25 of the U-shaped bolt 23.
The tips 25, 25 are set to be sufficiently long.

Next, the antenna arm 21 equipped with the antenna element 20 is rotated 90 degrees downward in FIG.
The tip portion 25.2 of the U-shaped bolt 23 is attached to the end on the base surface 7 side of 10.
5, and tighten them with wing nuts 26 and 26 to secure them.

The change from vertical polarization reception to horizontal polarization reception is performed in exactly the same manner.

In addition, in this mounting tool, the mounting angle within the vertical plane of the antenna arm 21 can be adjusted by moving the tip 14 of the U-shaped bolt 11 within the arc-shaped elongated hole 15.

Next, the second embodiment shown in FIGS. 5, 6, 7, and 8 will be described.

It should be noted that components having the same functions as those in the previous embodiment are given the same reference numerals.

This embodiment differs from the previous embodiment in that there is no dedicated mast support member 3, and that the antenna support member 27 is not provided with an arcuate long hole 15 for adjusting the mounting angle on the vertical plane of the antenna arm 21. are exactly the same.

A mast support surface 29 is formed in the upper center of the upright surface 28 of the antenna support member 27 by being bent outward, and a pressing recess 30 is provided at the end surface of the mast support surface 29 .

In addition, a U-shaped bolt 11 is provided near the upper side surface of this upright surface 28.
Through holes 31, 31 are bored through which the distal end portions 12, 14 of the tubes are inserted.

Although the mounting angle of the antenna arm 21 in the vertical plane cannot be adjusted in this embodiment, the antenna element 20 can be easily changed from horizontal to vertical, and from vertical to horizontal.

In the third embodiment shown in FIG. 9, FIG. 10, FIG. 11, and FIG. The only difference is that 33.33 is used, and everything else is exactly the same.

The antenna support member 32 has a square-shaped pressing recess 36 formed in the vertical direction of the center of the upright surface 34 of the mast 1 .

Note that the antenna arm 21 is attached to the antenna support member 6.27.
．． This idea, which can also be done with bolts instead of the U-shaped bolts 23 to attach the antenna to the mast 32, is made by placing the press fitting and the antenna support member having a U-shaped cross section facing each other on the outer circumferential surface of the mast, as described above. Then, the bolt is engaged with the upright surface of the antenna support member, and the tip of the bolt is passed through both sides of the mast and inserted into the press fitting to screw the nut, An antenna for both horizontal and vertical use, in which a long hole is bored in two places across the base surface bent in the shape of a shape, a bolt is engaged with the antenna arm, the tip of the bolt is inserted into the long hole, and a nut is screwed. This is a mounting bracket that allows you to easily and reliably change the horizontal or vertical orientation of the antenna with just one mounting bracket.Moreover, the antenna does not need to be separated from the fixture, so there is no chance of losing bolts, nuts, etc. Not at all.
