Description

[Detailed description of the invention] The present invention relates to the invention of a retractable antenna mounting device for automobiles, which is suitable for use when entering a garage or driving in a forest with the antenna attached to the automobile sufficiently protruding from the vehicle body. An object of the present invention is to provide an antenna mounting device for an automobile, which can be brought into a lowered state with a sound if the antenna is hooked.

The antenna is indispensable as reception equipment in a car, and in order to create a good reception condition, it is necessary to make the antenna protrude from the surface of the car to a certain extent and make it high enough for the driver. By choosing a position that does not obstruct the view of passengers, passengers, etc., it is possible to enter the vehicle without being aware that it remains protruding for a long time when entering a garage, washing the car, or driving through a forest. Therefore, in these cases, there are many accidents that result in damage to the installed antenna.

Of course, such accidents can be avoided by storing or laying down the antenna, but in order to store or lay down the antenna, the driver or the like must take the trouble to get out of the car, operate it, and then get back in the car and drive. It's normal to have to do without it, and it's extremely annoying.

It is well known that such automobile antennas are grounded on the vehicle body, so it is necessary to introduce a cable for feeding power to the antenna at the base end of the antenna. When an automobile antenna connected to the base end is raised or lowered, the conventional mounting device has the disadvantage that the cable obstructs the operation, making it difficult to obtain a preferable raising and lowering operation.

The present invention was devised through research to eliminate the disadvantages and drawbacks of the conventional automobile antennas as described above, and the specific embodiment thereof is shown in the attached drawings. A seating body 1 and an antenna 3 are provided with legs 11 facing each other to be fixed in a predetermined state, and can be tilted inwardly and outwardly of the vehicle body by means of an axis as shown on the left side of FIG. An antenna mounting hole 21 for mounting the base of the antenna and fixing it with a required fastening member 4.4 is provided diametrically through the antenna mounting hole 21. The base body 2 is rotatably fitted and assembled from the base body 2 and the lid body 5 is fitted to the annular portion 12 from the other side. A circular protruding seat 50 similar to the circular protruding seat 20 for fitting is formed, and these circular protruding seats 20, 50 are opposed from both sides of the annular part 12 and fitted into the annular part 12, such as a stopper 29. Both parts 2 and 5 are fixed and form a rotatable fitting relationship.

However, between the fitting portions of the base body 2 assembled as described above, that is, the circular protrusions 20 and 50, and the inner surface of the annular portion 12, an elastic material 24 is installed in the perforated portion 23, and the engaging element 22 is inserted. An arc-shaped notch 25 is formed at a position opposite to the perforated portion 23, and an elastic plate 26 is attached to make elastic contact with the opposing surface. A plurality of recessed grooves or recessed hole-shaped engaging portions 27 are arranged on the surface.

As shown in the figure, a cable 6 for connecting to an on-vehicle power source is connected to the base end of the antenna 3 and pulled out from the mounting hole 21, and a plug 7 is provided on the cable 6.

In the illustrated example, the inner surface of the annular portion 12 is formed into a thin layer to prevent the annular portion 12 from forming the elastic plate 2.
6, and a retaining part 27 is disposed on this, and an engaging element 22 and an elastic plate 26 are attached to the circular protrusions 20 and 50, and one of them (for example, the elastic plate 26) is attached to an annular part. 12 side, and only the other side (for example, the engager 22 with the elastic material 24 inside) can be provided on the circular protrusion side.

Concerning the height of the two circular protrusions 2G and 5G, that is, the depth of engagement with the annular portion 12, the circular protrusion 20 is made sufficiently high, contrary to what is shown in the figure, and the circular protrusion 50 is simply a cover body. Based on the positioning degree of 5, therefore, the above-mentioned retainer 22
Also, the elastic plate 26 may be attached entirely on the circular protrusion seat 50 side.

According to the present invention as described above, the base body and the lid body, which are rotatably fitted and assembled to the annular part of the seating body, are held in a desired position by the retainer and the elastic plate containing an elastic material inside. The antenna 3 mounted in the antenna mounting hole is set at a predetermined angle with respect to the vehicle body to which it is mounted, and is rotated appropriately to raise and lower the antenna in the longitudinal direction of the vehicle, that is, as described above. If an abnormal external force is applied to the antenna set as described above, such as when entering a garage or washing a car, the engagement element will be disengaged and the base body 2 will be rotated under the pressure condition of the elastic plate. In other words, it is possible to lower the antenna to an appropriate position and avoid accidents such as breakage, and in addition, when the external force is not abnormally large as mentioned above, the elastic engagement between the engaging element and the elastic plate allows A stable antenna support state can always be formed by fitting and holding the base body and the lid body from both sides in the annular part of the seating part body, and between the circumferential surface of the fitting part and the inner surface of the annular part. Since the engaging element and the elastic plate are interposed in the annular part 12, the base body 2 and the lid body 5, which have relatively large diameters, are fitted into the annular part 12, which increases the strength of the antenna mounting mechanism for automobiles subject to strong vibrations. It is excellent in
The engagement and support by 7 is accurate, and since the antenna is attached by forming an antenna mounting hole in the sideward protrusion of the annular portion of the base body, it is easy to draw out the cable 6 that connects the antenna and the on-vehicle power source. In addition, the cable 6 pulled out does not interfere with the raising and lowering of the antenna, which together eliminates the complication of the driver having to get out each time he enters the garage, etc. It has the effect of allowing you to concentrate on driving, and is a highly effective device in practical terms.
