[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6126973 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional antenna hardware has different joints depending on the type, which limits the types of utility poles it can be installed on. The top equipment mounting device of Patent Document 1 also has a lower end attached to the pole and an upper end attached to the top equipment (rod-shaped antenna), so the poles and top equipment it can be used on are limited. Therefore, there was a demand for an antenna mounting fixture that could expand the range of possible installation targets while minimizing the impact on power equipment.

[0005] Furthermore, in view of the need to mount the antenna on a large number of poles, it is necessary to consider an antenna mounting fixture that can be mounted easily and at low cost.

[0006] The present invention has been made in view of the above points, and an object of the present invention is to provide an antenna attachment that can be easily attached at low cost. [Means for solving the problem]

[0007] In order to achieve the above object, the first invention is: An antenna mounting fixture that connects a top mounting fixture installed on the top of a pole and an antenna support fixture that supports an antenna, a base portion provided with a plurality of first fixing holes for fixing various types of the top mounting fixtures; a mount provided on an upper surface of the base and covering a threaded portion of a fixing bolt that passes through the first fixing hole and protrudes from the upper surface of the base; The antenna support is characterized by comprising a connecting portion that stands upright from the mount and can be fixed to the lower end of the antenna support.

[0008] According to the above configuration, the antenna mounting fixture of the present invention can utilize existing top mounting fixtures used in power equipment and antenna supports, which are existing antenna components, and can be used with a variety of top mounting fixtures by selecting the first fixing hole that corresponds to the top mounting fixture to be used from the multiple first fixing holes provided in the base, making it highly versatile and enabling antennas to be mounted at low cost.In addition, the top mounting fixture and base are connected with bolts and nuts, but because a stand that covers the threaded portions of the fixing bolts is provided between the base and the connecting portion, there is no need to consider interference with the threaded portions, and the insertion, installation, and tightening of the bolts and nuts between the top mounting fixture and base are easy, resulting in excellent workability.

[0009] In the second invention, in the first invention, the connecting portion is a cylindrical body that can be inserted into the insertion hole of the antenna support, The mount is characterized by including a flat plate portion on which the connecting portion stands, and the flat plate portion having an air hole that connects the inside of the tube of the connecting portion to the outside.

[0010] According to the above configuration, the antenna can be easily attached by inserting the connecting part into the insertion hole of the antenna support. Furthermore, when inserting the connecting part into the insertion hole, air escapes through the air holes provided in the flat plate part of the mount, reducing resistance during insertion and saving labor. Furthermore, the air holes also function to drain water if it gets into the connecting part.

[0011] In the third invention, in the second invention, the antenna support is cylindrical with the insertion hole inside the tube, The connecting portion is cylindrical and can be inserted into the insertion hole, and has a second fixing hole at a position corresponding to the fixing hole provided in the antenna support.

[0012] With the above configuration, the antenna can be attached more easily by inserting the connecting part into the insertion hole of the antenna support. Furthermore, by fixing the antenna support and the connecting part in the second fixing hole, rotation and falling off of the antenna support can be prevented, allowing for safe attachment.

[0013] In a fourth aspect of the present invention, in the first aspect of the present invention, the top fixture has a flat surface at an upper end; The base portion is flat and configured so that it can be placed on the flat surface of the top mounting fixture and fastened with screws.

[0014] According to the above configuration, the flat surface of the top mounting fixture and the flat base can be fixed in close contact with each other, so that the antenna can be stably attached to the top mounting fixture. [Effects of the Invention]

[0015] As described above, according to the present invention, it is possible to provide an antenna attachment that is low cost, highly versatile, and easy to attach. [Brief explanation of the drawings]

[0026] Then, the connecting part 30 is inserted into the insertion hole 301a of the antenna support 300, and the second fixing hole 34 is aligned with the position of the fixing hole 303 of the antenna support 300. Then, the fixing bolt 60 is inserted through the fixing hole 303 and the second fixing hole 34 of the antenna support 300 to fix the antenna mounting fixture 100. Note that it does not matter whether the base 10 is fixed to the top mounting fixture 200 or the connecting part 30 is fixed to the antenna support 300 first.

[0027] The antenna mounting fixture 100 configured as described above can utilize the top mounting fixture 200, which is an existing part used in power equipment, and the antenna support 300, which is an existing part for the antenna Y, making it possible to mount an antenna at low cost. Furthermore, by selecting the first fixing hole 11 corresponding to the top mounting fixture 200 to be used from the multiple first fixing holes 11 provided in the base 10, it is possible to accommodate a variety of top mounting fixtures, making it highly versatile and allowing antennas to be mounted easily. Furthermore, the top mounting fixture 200 and the base 10 are connected with fixing bolts 40 and nuts 50, but because a platform 20 is provided between the base 10 and the connecting portion 30 to cover the threaded portions of the fixing bolts 40, there is no need to consider interference with the threaded portions, and the insertion, installation, and tightening of the bolts and nuts of the top mounting fixture 200 and the base 10 are easy, resulting in excellent workability.

[0028] Furthermore, antenna Y can be easily attached by inserting connecting part 30 into insertion hole 301a of antenna support 300. When connecting part 30 is inserted into insertion hole 301a, air escapes through air holes 33 provided in mount 20, reducing resistance during insertion and saving labor. Air holes 33 also function to drain water if water gets into connecting part 30.

[0029] (Other usage conditions) Next, another state of use of the present invention will be described with reference to Figure 8. In this state of use, the antenna attachment device 100 and the antenna support device 300 have the same configuration as those described above, with only the configuration of the top attachment device being different. In the following description, the same components as those in the above state of use are given the same reference numerals, and their description will be omitted.

[0030] In Figure 8, top mounting fixture 210 has fastening portion 211 at its lower end for fastening to support column X, and flat surface 212 at its upper end. Flat surface 212 has fixing holes 213 that penetrate vertically. When mounting antenna mounting fixture 100, base 10 is placed on the upper surface of flat surface 212 of top mounting fixture 210, and an appropriate fixing hole among first fixing holes 11 in base 10 is aligned with the position of fixing hole 213 in flat surface 212. In this way, even if a different type of top mounting fixture 210 is used, antenna mounting fixture 100 of the present invention can be fixed by selecting a fixing hole among the multiple first fixing holes 11 that corresponds to that top mounting fixture and aligning it with the fixing hole in top mounting fixture 210, making it compatible with a wide variety of top mounting fixtures 210 and highly versatile.
