Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an antenna mounting bracket, and more particularly, to a mounting bracket for mounting an antenna on a draw-in pillar such as a power line or a telephone line.

[Conventional technology]

The television viewing antenna is generally mounted on the end of a pipe erected on the support base, and the support base is installed on the roof of the house, and a branch line is attached to the pipe or support base to prevent collapse due to wind pressure etc. It has a structure. As another method of mounting the television viewing antenna, there is a method in which the antenna support is directly mounted on a rafter on the eaves of a house and fixed.

However, in recent years, a change in the roof structure of a house has made it difficult to install a television viewing antenna on a roof or eaves, and the mounting work has become dangerous. Therefore, alternative methods are required.
2. Description of the Related Art There has been used a small pillar for dropping a power line or a telephone line from a main line to a house.

The service pillars are mainly installed outdoors on the premises of the house, and power lines and telephone lines are drawn from the utility poles to the service pillars, and those wires are directly drawn into the house from the service pillars or are serviced. It is designed to be drawn indoors from the ground through the inside of the work pillar. As shown in FIG. 6, an antenna support 3 for supporting the antenna 2 is attached to the leading pillar 1 via an antenna fitting 4 as shown in FIG. The antenna mounting bracket 4 has a U-shaped draw-in pillar fixing portion 5 that covers about half of the outer circumference of the pull-in pillar 1 and a U-shaped antenna support that covers about half of the outer circumference of the antenna support 3. A pair of divided pieces 7 integrally formed with the fixing part 6 are abutted against each other, and the small retracting column 1 and the antenna support 3 sandwiched between the divided pieces 7 are tightened with bolts and nuts 8. .

[Problems to be solved by the invention]

When the bolts and nuts 8 at an arbitrary position are loosened, the overall tightening force of the antenna mounting bracket 4 having such a structure is loosened, and the antenna mounting bracket 4 slides down from the retractable column 1 or the antenna column 3 is It slipped off the antenna mounting bracket 4 and had poor workability. In particular, the direction of various antennas including the television viewing antenna is important, and it is necessary to adjust the antenna to the direction having the best sensitivity and fix the antenna support 3. However, when the bolts and nuts 8 are loosened for fine adjustment, the entire body is loosened. Therefore, it is difficult to perform a quick and reliable operation alone with the conventional antenna support bracket 4.

In addition, the conventional antenna mounting bracket has almost the same structure as the above-described antenna mounting bracket 4, or simply ties the retractable small pillar and the antenna support together with a band member, and has the same problem. .

Therefore, the present inventors can quickly and reliably attach the antenna support to a pole such as a retracting small pillar,
Moreover, as a result of intensive studies to provide an antenna mounting bracket capable of easily performing fine adjustment of the direction, the present invention was reached.
