Description

[Detailed description of the invention] The present invention relates to the invention of an antenna mounting base for a vehicle, which allows the antenna base to be attached to the gutter of the vehicle body to be tilted horizontally or otherwise with simple operation. In addition, in a vehicle antenna mounting base that can form a stable and accurate antenna support/mounting state in each state, the assembled state may be affected by incorrect operation such as turning a push button or repeated antenna raising/lowering operations. It is designed to ensure accurate operation over a long period of time by eliminating the possibility of disassembly from the assembled state.

Conventionally, various methods have been used to attach antennas using rain gutters of automobiles. In other words, the conventionally commonly used such mechanism is one in which the antenna is mounted vertically on a base that is fixed to the rain gutter. There are some antennas that can be installed vertically, but if the antenna is simply installed vertically, the antenna becomes a hindrance when entering places with low ceilings such as garages or underground parking lots. Therefore, some proposals have been made to be able to tilt forward and backward in the direction of approach when entering a place with a low ceiling, but there are cases where the tilting operation is difficult, or the tilting operation is difficult. This has the disadvantage that the support state of the antenna becomes unstable.

In other words, as mentioned above, in order to tilt the antenna back and forth in the vehicle's approach direction, it is common to tighten the center part of the mounting base on which the antenna is attached to the base with a screw rod, but this does not apply. It is essential to rotate and loosen the tightened state of the screw rod in order to tilt the rod, and the operation is complicated, especially since it is necessary to go outside the vehicle. If this happens, the long protruding antenna will not be supported properly. On the other hand, if the antenna is supported by the tension of a spring or the like, if the tension of the spring is large, it is difficult to tilt the antenna, and if the tension is insufficient, the antenna, which was vertically held up, may be exposed to air when the vehicle is running. It has disadvantages such as being prone to tilting due to resistance and wind force.

However, the inventor of the present invention has researched to eliminate the disadvantages and drawbacks of the conventional ones as described above, and has developed a base that is attached to a vehicle body gutter, a base body attached to the base, and a base body attached to the base. The base body has an antenna mounting seat that is tiltably provided, and a locking body that has a locking portion is provided on the shaft of a push button that is provided with a spring inside the base body; An engaging part that engages with the engaging part is formed on the inner surface of the base body, and the elastic force of the spring causes the engaging part to engage with the engaging part, and pressing the push button causes the engaging part to engage with the engaging part. He proposed to liberate himself from the state of conflict (Utility Application No. 57-55612: Utility Model Application No. 158511-1981). In other words, according to the prior art of the present inventor, in this type of antenna mounting mechanism that is attached to the rain gutter of an automobile, the vertical antenna can be raised and tilted back and forth in the direction of movement of the vehicle body. Moreover, the operation can be easily performed with a single push of a button, and in particular, the operator can easily put his/her hand out of the window while riding in the vehicle, and in addition, the antenna support relationship is outstanding. It has effects such as stability, and is very significant in practical use.

However, according to the results of actual commercialization and repeated studies of this product, operators generally have a habit of rotating the push button body,
Furthermore, since the shaft part provided integrally with the push button part body is screwed onto the locking part body, if the push button part body is mistakenly rotated in the opposite direction to the threaded engagement, it will cause damage. The push button body will come off from the locking body for the lock part of the seat body. In particular, if the vehicle is driven with the push button body detached or on the verge of detachment, there is a high possibility that the push button body outside the vehicle will fall off onto the road due to the vibrations of the vehicle and be lost along with the spring. Also, when tilting the antenna by pressing the push button body in the palm of your hand, if the push button body is not pushed in enough, the locking part of the locking part may cut into the notch in the base body. In this state, rotational force is applied to the push button body in the palm of the hand. That is, in this case, only the push button body rotates relative to the fixed locking body, and the threaded engagement between the push button body and the locking body loosens in the same way as above. As mentioned above, under the condition that only the hand is held out of the car window and the fingers of the hand are bent upward, the operation is carried out in a state where the gutter outside the car is hardly visible, and the loosened state is almost never recognized. , there is a high possibility that relaxation will accumulate.

Furthermore, since the antenna tilting operation described above is the rotation of the antenna mounting seat with respect to the base body, the nut for mounting the antenna mounting seat on the shaft cylinder part loosens due to the rotation of the antenna mounting seat, and this loosening accumulates. There is a possibility that the central part where the entire mechanism is attached may be separated and disassembled. In particular, there is a high possibility that the above-mentioned loosening of the push button body and this loosening of the nut proceed in parallel, and if they proceed simultaneously, substantially the entire mechanism may disintegrate and be lost due to vibrations caused by vehicle running. Become.

The present invention was devised after further study in view of the above-mentioned circumstances, and includes a base that is attached to a vehicle body gutter, a base body attached to the base, and an antenna mounting seat that is tiltably provided on the base body, and a rectangular nut screwed onto the shaft cylindrical portion of the antenna mounting base, and a locking member that is a washer-like member. assembling a push button via a connecting means and a spring, connecting a locking part having a locking part on the shaft of the push button and located between the antenna mounting seat and the base body; An engaging part that engages with the engaging part is formed on the inner surface of the part, and the engaging part is engaged with the engaging part by the elasticity of the spring, and the engaging part is engaged with the engaging part by pressing the push button.
