Abstract

PROBLEM TO BE SOLVED: To improve job performance in an antenna base mount and to reduce the job time by providing a magnet in the vicinity of a thread hole. SOLUTION: A thread hole 2 used to screw-fasten to a ceiling 5 is formed onto an antenna base 1. Furthermore, a magnet 8 is provided in the vicinity of (at the surrounding of) the thread hole 2. In the case of mounting the antenna base 1 to the ceiling 5, a press contact face of the antenna base 1 to the ceiling 5 is pushed onto the ceiling and the presence of a metallic rail 6 is discriminated depending on the strength of force attracting the antenna base 1 to the metallic rail 6 with a magnetic force of the magnet 8 and when the thread hole 2 comes beneath the metallic rail 6, the antenna base is screw-fastened to the metallic rail 6 via the thread hold 2 and the ceiling 5 with a screw 3. Then the antenna and the antenna cover 4 are mounted onto the antenna base 1 to mount the antenna system onto a ceiling face complete.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antenna base mounting type antenna device in which an antenna base is mounted on a wall surface or a ceiling surface.

[0002]

2. Description of the Related Art Conventionally, in this type of antenna base mounting type antenna device, when mounting the antenna device on the ceiling 5, as shown in FIG. After measuring the position of the metal rail 6 that is installed, determine the installation position of the antenna base 1, then place the antenna base 1 at the installation position on the surface of the ceiling 5 and support it by hand, and use the screw Then, the screw 3 is attached to the metal rail 6 through the screw hole 2 of the antenna base 1 and the ceiling material 5, and finally the antenna (not shown) and the antenna cover 4 are attached to the antenna base 1.

[0003]

However, in the antenna base mounting type antenna device as described above, the mounting work of the antenna device is very time-consuming and time-consuming.

The present invention has been made in view of the above points, and it is an object of the present invention to improve workability and shorten work time in mounting an antenna device of an antenna base type. An object is to provide an antenna device that can be used.

[0005]

According to the first aspect of the present invention,
An antenna device in which an antenna base having a screw hole is attached to a wall surface or a ceiling surface with a screw,
A magnet is provided in the vicinity of the screw hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing a state in which an antenna device showing an example of an embodiment of the present invention is attached to a ceiling surface. Reference numeral 1 is an antenna base, and a screw hole 2 for screwing to the ceiling 5 is formed. A magnet 8 is provided in the vicinity (peripheral portion) of the screw hole 2. 3 is a screw for attaching the antenna base 1, and 4 is an antenna cover.

When the antenna base 1 is attached to the ceiling 5, the contact surface of the antenna base 1 with the ceiling 5 is the ceiling 5.
The antenna base 1 by the magnetic force of the magnet 8
The presence of the metal rail 6 is determined by the strength of the force attracted to the metal rail 6, and when the screw hole 2 is located directly below the metal rail 6, the screw 3 causes the screw hole 2 and the ceiling 5 to pass through. Screw on the metal rail 6. After that, the antenna (not shown) and the antenna cover 4 are attached to the antenna base 1 to complete the attachment of the antenna device to the ceiling surface.

By doing so, the mounting position of the antenna base 1 can be easily determined without measuring the mounting position of the metal rail 6 with a measure or the like.

In this embodiment, the antenna base 1
Although the example of attaching the to the ceiling 5 has been described, the same effect can be obtained even when attached to the wall.

[0010]

As described above, according to the invention described in claim 1, there is provided an antenna device in which an antenna base having a screw hole is attached to a wall surface or a ceiling surface by a screw, and a magnet is provided near the screw hole. Since it is provided, when mounting the antenna base on the wall surface or ceiling surface, the magnets provided near the screw holes of the antenna base can easily determine the position of the metal rails inside the wall or ceiling. As a result, it is possible to provide an antenna device capable of improving workability and shortening work time in the mounting work of the antenna base mounting type antenna device.
