I try to do that.

Further, the other end of the fastening piece 32 has a flange portion 35 formed in a projecting shape.
This makes it possible to fasten the antenna fixing member 8.

A case will be described in which an antenna is attached to a car using the antenna mount 4 having the above configuration.

Usually, first, the fastening member 6 of the fixture 4 is fastened to the automobile.

In this case, as shown in FIG. 3, a part of the rain gutter 2 of the automobile is positioned within the concave fastening portion 10 of the fastening member 6, and fastened by tightening a threaded rod 11 as is well known.

Next, the support member 7 is bonded and fixed to the fastening member 6 fixed as described above.

In this case, as shown in FIG. 8, the arcuate joint surface 16 of the support member 7 is brought into contact with the outer surface of the cylindrical joint portion 12 of the fastening member 6, and the fixing screw 18 is tightened using a well-known screwdriver. The support member 7 is screwed onto the shaft body 14 located within the joint portion 12 from the outside (the side opposite to the joint surface 16) using a screwdriver.

As a result, the shaft body 14, which is integrally connected to the joint surface 16 of the support member 7 and the support member 7 by the tightening fixing screw 18, is connected to the outer surface and the inner surface of the joint portion 12 of the fastening member 6, respectively. By adhering the outer surfaces, the contact resistance of the support member 7 to the fastening member 6 inevitably increases, and the support member 7 is firmly bonded and fixed.

Next, the antenna fixing member 8 is attached to the support member 7 fixed to the fixing member 6 as described above.

In this case, the rotation stop portion 29 of the fixing member 8 is fitted into the engaging portion 23 of the support member 7, and the fixing member 8 is
is fastened to the support member 7.

At this time, the position of the tightening screw 31 within the elongated hole 28 in the fixing member 8 is located upward as shown in FIG.

In this way, the antenna 3 is fixed to the fixing member 8 and established with respect to the fixture 4 attached to the rain gutter 2 as shown in FIG.

In addition, if the antenna established at this time is tilted to the inside or outside of the vehicle body depending on the angle at which the fastening member 6 is attached to the rain gutter, tighten the fixing screw at the joint between the fastening member 6 and the support member 7 mentioned above. 18 is loosened to allow the support member 7 to tilt with respect to the fixing member 6, and the tilting of the support member 7 is adjusted so that the antenna is in a good established state.

Thereafter, the screws 18 are tightened again to fix the support member 7.

Incidentally, the above-described mounting operation order is one example thereof, and the mounting operations may be performed in any order according to preference.

For example, the support member 7 is
When fixing, the fixing member 8 with the antenna attached is fixed to the support member 7 in advance, and when the support member 7 with the antenna attached is fixed to the fixing member 6, the fixing member 8 is fixed at the same time. The antenna may be installed by adjusting its tilt.

Next, when the antenna 3 established by the fixture 4 as shown in Fig. 1 gets in the way while driving the car, for example when parking the car in a garage, rotate the antenna fixing member in the fixture 4. If the antenna 3 is tilted toward the rear of the vehicle 1 as shown in FIG. 2, the vehicle can be smoothly parked in the garage without removing the antenna 3.

When performing the above rotation operation, first loosen the tightening screw 31 on the antenna fixing member 8 which is in a tightened state with the tightening screw 31 as shown in FIG. Solve the condition.

Next, when the fixing member 8 is lifted in the lifting direction, the rotation stopper 29 shown in FIG.
When removed, the fixing member 8 becomes rotatable relative to the fastening member 6.

From this state, when the fixing member 8 is rotated in the direction of arrow 35 shown in FIG.
0 slides on the guide wall 22 of the support member 7, and the side portion 27a of the fastening piece 27 comes into contact with the stopper portion 20.

As a result, the antenna provided on the fixing member 8 falls down, and by tightening the tightening screw 31 in this state, the fixing member 8 is fixed to the support member 7 again.

In addition, when the antenna fixing member 8 of the fixture 4 is rotated as described above and the antenna is folded down as shown in FIG. This can be easily done because there is a part (antenna fixing member 8) that can be folded down within reach from inside the vehicle (driver's seat).

Furthermore, with the conventional top element that can be folded down, it is difficult to secure the antenna element when the top element is folded down, making it difficult to drive in the folded state. Since the state after rotation can be maintained in a fixed manner, it is possible to drive a car with the antenna tilted down.

In order to make the opposite antenna stand upright again as shown in FIG. 1, the above procedure can be performed in the reverse order.

Next, FIG. 9 will be explained.

This figure shows a configuration in which the fastening member 6e of the antenna mount 4e is provided with an auxiliary metal fitting 40, and even if the rain gutter 2e as an attached member of a car has a different shape as shown in the figure, the fastening member 6e can be fixed. An example is shown in which the auxiliary metal fitting 40 connected to the upper collar 10ae of the member 6e is attached as shown in the figure, and the auxiliary metal fitting 40 can be attached by tightening the tightening threaded rod 11'e.

It should be noted that parts that are considered to have the same or equivalent structure as those in the previous figure in terms of function are given the same reference numerals as in the previous figure with the letter e, and redundant explanations are omitted.

As described above, in this invention, since the support member 7 is tiltably fixed to the fixing member 6, the fixing member 6 is attached to the antenna attachment member 2 in an automobile.
Regardless of the attachment angle, the support member 7 can always be attached to the fastening member 6 in a desired upright position, and the attached position can also be adjusted and fixed.

This means that the antenna fixing member 8 provided on the support member 7
On the other hand, it is effective to properly establish the antenna 3, which is fixedly attached, and to perform good transmission and reception.

Moreover, when attaching the support member 7 to the fastening member 6, the tightening fixing screw 18 is screwed onto the rotatable shaft body 14 inside the joint 12 of the fastening member 6 from the outside of the support member 7. and in the tightened state, the outer surface of the joint portion 12 of the fastening member and the support member 7
At the same time that the arc-shaped joint surface 16 is joined, the outer surface of the shaft body 16 and the inner surface of the joint portion 12 are also joined, thereby doubling the joint surface.

This is extremely effective in preventing the support member 7 from moving relative to the fastening member 6.

That is, the support member 7 for the fastening member 6 is attached to the joint surface 16 of the support member 7 and the support member 7 with respect to the outer surface and the inner surface of the cylindrical joint portion 12 of the fastening member as described above. On the other hand, since both sides of the outer surface of the shaft body 14, which is connected and integrated, are joined to each other, the contact resistance is doubled.
It has the advantage of providing an extremely firm fixation.

In this civil engineering design, since the position of the hand tightening the tightening fixing screw 18 is located on the opposite side of the fastening member 6 from the fastening part 10, if the fastening part 10 is Even when a long object such as a gutter is inserted, there is an advantage in the installation work that the tightening fixing screw 18 can be tightened (operation using a large screwdriver) without being affected by the long object.
