SUMMARY OF THE INVENTION An antenna support structure of the present invention rotates about an upright part formed by arranging a plurality of locking parts and a shaft part provided on a foot part sandwiching the upright part. And at least a tubular support for inserting and holding a part of the antenna from the side opposite to the foot, wherein each of the locking portions is separated from the tubular support. It is formed in a concave shape that engages with the protruding base side end of the antenna to fix the rotational position of the tubular support part, and stands up at this foot part by narrowing the interval between the foot parts as the shaft part. By using a structure in which the rotational position of the tubular support portion is fixed by sandwiching the portion, the rotational state of the tubular support portion is fixed by the engaging action of the locking portion and the base side end portion. In addition to the fact that the foot is sandwiched by the standing portion, its rotation state is arbitrary. Is obtained so as to be fixed in location. Further, screw coupling may be used between a part of the antenna and the cylindrical support portion.

As described above, by holding the antenna on the tubular supporting portion, the end portion on the base side of the antenna engages with the locking portion, so that the rotational position of the tubular supporting portion is fixed at the same time when the antenna is attached. As a result, the antenna held by the tubular support portion is also held in the predetermined direction.

Further, since the space between the legs of the tubular support portion is narrowed by the shaft portion so that the upright portion is sandwiched by the legs, the base-side end portion and the locking portion are connected to each other. In addition to the above-mentioned engagement, the rotation position of the tubular support portion can be fixed by sandwiching the standing portion by the foot portion, whereby the direction of the antenna can be held more strongly.

Further, the turning position of the cylindrical support portion may be fixed by either one of the above two means. Therefore, even when the base-side end portion and the locking portion are not engaged with each other, the rotation position of the tubular support portion can be arbitrarily fixed by sandwiching the standing portion with the foot portion.

The upright portion 2 is attached to the base portion 1 by sandwiching a part of the base portion 1 with the holding plate 3 and fixing the holding plate 3 with a screw 4. In addition,
The base 1 is provided with a mounting member, a magnet and the like for mounting to a mounting portion such as a vehicle (not shown), and the standing portion 2 and the screw 4 are both formed of an electrically conductive material, The two are connected to each other.

The coaxial cable 8 has its end attached to a screw 4, and the standing portion 2 is inserted through the screw 4.
It is in the state of being connected with. Furthermore, the standing portion 2 is
A hole 2b is provided at the center, and a plurality of locking portions 2a are formed at regular intervals on a semicircular edge portion. Each of the locking portions 2a is a base portion of an antenna 7 described later. It is formed in a concave shape so that the side end portion 7a is fitted.

The tubular support portion 5 has a threaded portion provided on the inner peripheral surface 5a, and the standing portion 2 is sandwiched by two foot portions 5b provided on the lower portion, and the foot portion 5b is formed. By mounting the bolt 6 with the hole 2b penetrating from the outside, the bolt 6 is set so as to be rotatable about the bolt 6 with respect to the upright portion 2. The tubular support portion 5 is made of a material having no electrical conductivity, but the material is not limited to this.

As described above, by using the bolt 6, when the bolt 6 is tightened, the leg portion 5b sandwiches the upright portion 2, whereby the cylindrical support portion 5 is rotated at an arbitrary rotational position. It can be fixed to. Note that the bolt-shaped member is not limited as long as the standing portion 2 is sandwiched between the foot portions 5b.

Subsequently, the antenna 7 is formed such that the base-side end portion 7a projects downward from the cylindrical support portion 5 when the base-side portion is inserted into the cylindrical support portion 5. On the outer peripheral surface of the portion, a screw portion that can be joined to the screw portion of the inner peripheral surface 5a is formed. In addition, the base-side end portion 7a has the locking portion 2
It is formed in a shape that can be fitted into a.

Next, the use state, that is, the state where the antenna 7 is attached, will be described. First, while rotating the antenna 7, the base side end portion 7a is put into the cylindrical support portion 5, and both the base side end portion 7a are placed. It is moved downward by the action of the screw part. Then, the base-side end portion 7a is inserted further deeply so as to project from the tubular support portion 5 and fitted into one of the plurality of locking portions 2a, and when downward movement is locked, screw connection of both is completed. However, the two are in an integrated state.

Since the base-side end portion 7a is integrated with the tubular support portion 5 in a state where the base-side end portion 7a is fitted in the locking portion 2a, the tubular support portion 5 is connected via the base-side end portion 7a. The rotation operation is restricted. This allows the antenna 7
Is fixed to the upright portion 2 (base portion 1) at a predetermined rotation position. At this time, the antenna 7 is in a state of being connected to the coaxial cable 8 via the base-side end portion 7a-the upright portion 2-bis 4.

Further, as shown in FIG. 2, by inserting a screwdriver or the like through the window portion 1a provided in the base portion 1 and tightening the bolt 6, the base side end portion 7a is fitted into the locking portion 2a and is tubular. In addition to restricting the rotation of the support portion 5,
The tightening of the bolts 6 also restricts the turning, so that the turning position of the tubular support 5 can be strongly held.

Therefore, the base side end 7a and the locking portion 2a
Even when the and are not engaged, that is, the base-side end portion 7a is not fitted in the locking portion 2a, the rotation of the tubular support portion 5 can be restricted by tightening the bolt 6. As a result, the orientation of the antenna 7 is changed to the locking portion 2
It is possible to arbitrarily adjust regardless of the position of a.

As shown in FIG. 1, when the direction of the antenna 7 is changed, the antenna 7 is rotated to move the base-side end 7a upward to disengage it from the engaging portion 2a, and the tubular support portion. 5 is rotated to a desired angle about the bolt 6 as an axis, and at this rotating position, the corresponding locking portion 2a
This can be done by fitting the base side end portion 7a again.

Further, although the one shown in the figure uses screw coupling to integrate the base side portion of the antenna 7 and the cylindrical support portion 5, the present invention is not limited to this, and any coupling method,
For example, a protrusion may be formed on the base side portion and a guide groove may be formed on the inner peripheral surface 5a, and the protrusion may be guided by the guide groove to join the two together for integration. Further, the base-side end 7a is not limited to be fitted into one locking portion 2a, and may be shaped so as to fit over a plurality of locking portions 2a, for example, two locking portions 2a. It may be.

According to the present invention, a part of the antenna is put into a rotatable cylindrical support part to integrate them, and at the same time, the engaging part of the standing part and the end part on the base part are engaged with each other. Since the rotation of the tubular support portion is regulated, the antenna can be attached and the orientation of the antenna can be determined at the same time by one procedure such as inserting the base end into the tubular support portion. It is possible for the user to easily handle the work and to shorten the working time.

Further, since the standing portion can be sandwiched between the legs of the tubular support portion by the shaft portion, the rotational position of the tubular support portion can be fixed, so that the locking portion and the end portion on the base portion side can be fixed. In addition to the engagement, the orientation of the antenna can be strongly maintained, and the tubular support can be fixed at that position even at any rotational position where the engagement between the locking portion and the base-side end is released. The direction of the antenna can be adjusted more finely.
