Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a vehicle antenna mounting device used, for example, when installing a radio station or the like in a vehicle.

[Prior art and its drawbacks]

Conventionally, general antenna mounting devices, for example,
It is attached to a car as shown in Figure 0. That is, the metal fitting 12 to which the automobile antenna main body 11 is fixed is attached with a screw 17 to the projecting piece 16 of the metal fitting 15, which has a substantially L-shaped tip and a support piece 14 that supports the end of the holding metal fitting 13 on the other side. Fix it. Then, the molding 18 of the automobile is held by the metal fitting 15, the holding metal fitting 13, and the bolt 19, and the automobile antenna main body 11 is attached.

Further, as shown in FIG. 11, for example, the metal fitting 12 to which the automobile antenna main body 11 is fixed is attached to the mounting metal fitting 20 with screws 17, and the fitting 12 is attached between the support piece 21 of the mounting metal fitting 20 and the bolt 22. Gold 2
The above-mentioned automobile antenna 11 is attached by holding the bent end portion 18a of the molding 18 through the antenna 3.

However, in the configuration of the mounting device shown in FIG. 10, when the distance between the vehicle body 24 and the bent tip 18a of the molding 18 is narrow, as shown in FIG. Since the antenna 11 hits the vehicle body 24, it becomes difficult to attach the antenna 11. For example, as shown in FIG. 13, when the width of the molding 18 base is narrow, approximately L
Since the tip of the character-shaped portion 15a comes into contact with the vehicle body 24, reliable attachment cannot be performed. Here, if the bending dimension of the approximately L-shaped portion 15a of the metal fitting 15 is shortened to fit the narrow base of the molding 18, for example, as shown in FIG. If the convex portion 18b is formed, the fit of the substantially L-shaped portion 15a to the molding 18 deteriorates, so that the mounting state of the antenna 11 becomes extremely unstable. Furthermore, as shown in FIG. 15, for example, if the bending tip 18a of the molding 18 is wide, the tip 13a of the presser metal fitting 13 will not come into contact with the base of the molding 18, making it impossible to securely attach it. . Here, it is possible to lengthen the bent piece of the presser metal fitting 13, but
This aggravates the drawbacks shown in FIG. 12 above. Although not shown, the mounting device shown in FIG. 10 can also be used in the case of a car in which the upper end of the door frame directly acts as a rain gutter and there is no part corresponding to the base of the molding 18. Installation is difficult.

On the other hand, the configuration of the mounting device shown in FIG. 11 has drawbacks such as the fixing state of the antenna 11 becoming unstable if the bending tip 18a of the molding 18 itself does not have sufficient strength.

[Purpose of invention]

This idea was created in view of the above-mentioned drawbacks, and it can be used reliably even when the shape of the molding and the positional relationship between the molding and the vehicle body change, or even in the case of a car where the door frame is used as a rain gutter. Another object of the present invention is to provide an automobile antenna mounting device that enables stable mounting.

[Key points of the idea]

That is, the automobile antenna mounting device according to the present invention has a presser metal fitting having different lengths at both ends, which is fastened with a screw in opposition to the metal fitting having a substantially L-shaped portion that contacts the bottom surface of the molding of the vehicle body at one end. L
A support hole through which the tip of the presser metal fitting is inserted is formed in the support portion of the other end of the metal fitting that comes into contact with the bottom of the molding, and a support hole through which the tip of the presser metal fitting is inserted is formed at the tip of the support portion. An L-shaped support piece is provided opposite to the L-shaped support piece, and the bending dimension of the approximately L-shaped portion of this metal fitting is shortened, and an extension aid is provided on this L-shaped portion to extend the bending dimension.
