Description

[Detailed description of the invention] The present invention relates to the invention of an antenna raising/lowering mechanism, which can be attached to the vehicle body in an appropriate state, and can be easily and precisely raised/lowered with one-touch operation to achieve a state of high reception efficiency. The purpose of the present invention is to provide a mechanism in which the locking relationship is stable even when the antenna has a considerable length and weight.

Although it has been widely practiced to install antennas on vehicle bodies such as automobiles so that they can be raised and folded, it is not always easy to raise and lower such antennas. It protrudes to a height of 1 m from the base, especially for personal radio antennas.
An antenna that protrudes from the front, rear, or beyond, has a considerable weight and length, and maintains such an antenna in a stable state that does not fluctuate due to vibrations during driving when it is standing or lying down relative to the vehicle body. However, it is not easy to switch from the upright (or lying down) state to the lying down (or upright) state of something that is engaged so as to be held in a stable state in this way. In addition, a device that facilitates such a switching operation has the disadvantage that the above-mentioned antenna cannot be stably held in each state, especially in the upright state. Furthermore, although it is preferable that such an antenna can be mounted on the right or left side of the car body, or on the bonnet or other parts with various slopes, conventional antennas have been installed on the right or left side of the car body, respectively. If it is a dedicated antenna and should be installed on the right side, but it is installed on the left side, the direction of the antenna will be reversed, causing problems when entering the garage etc. Also, the angle of inclination of the set surface of the base body will be different. As a result, its standing angle fluctuates, and it has the disadvantage that it cannot necessarily be installed in a state where reception efficiency is high relative to the vehicle body.

The present invention was devised after repeated studies in view of the above-mentioned circumstances, and the embodiment thereof is shown in the attached drawings.As shown in Figs. A mounting bracket 3 for attaching to a gutter or other appropriate position on the vehicle body is attached with a connector 18 via an intervening body 15, and a joining step 10d is provided on both sides of the top of the base body 1.

A plurality of locking portions 51 are arranged, and these locking portions 51 lock into the engaging portions 21 arranged in the shaft hole 20 of the support body 2, and the locking portions 51 lock in the locking portions 21 arranged in the shaft hole 20 of the base body 1. It is formed in such a manner that it does not engage with the engagement part 11, but rotates with respect to the base body 1. In addition, a through hole 50 is formed in this shaft member 5, and a plurality of engaging portions 52 are formed on the circumferential surface of the through hole 50, and such a through hole 50 is inserted with an elastic material 7 so that the push button can be pressed. The push button body 6 is set, and the locking portion 62 formed on the circumferential side of the push button body 6 is engaged with the engaging portion 52 so that the push button body 6 slides in the axial direction within the through hole 50. The shaft portion 60 formed at the center of the push button body 6 is connected to the bottom hole 50a of the through hole 50.
The seat body 8 protrudes from the support body 2 and is attached to the outer surface of the support body 2 through a through hole 80 of the seat body 8. The square part 64 formed at the tip of the part 60 is connected to the square hole 9 of the joint plate 9.
0 and inserted into the joint plate 9
is screwed into the screw hole 65 of the shaft portion 60. Note that a lid 93 is appropriately provided on a portion of the joint plate 9 where the stopper 63 is inserted.

The seat body 8 described above is formed separately from the support body 2 as shown in FIG. 3 or FIGS. The through hole 80 is engaged with and disengaged from the joint portion 21, and the through hole 80 is connected to the stepped portion 6 of the shaft portion 60.
6, the catch seat 8 is adapted to slide together with the push button body 6, and a locking piece 84 is provided on the inner surface thereof, in addition to the locking protrusion 81, protruding longer than the locking protrusion 81. , the locking piece 84 can be inserted into or removed from the insertion hole 24 of the support body 2 into any one of the many insertion holes 19 arranged around the shaft hole 10 on the other side of the base body 1. is configured to be

The specific mounting relationship between the base body 1 and the mounting bracket 3 described above is as shown in the lower part of FIG.
An interposed part body 15 is used for the base part body 2, and the engagement teeth 16 formed on both sides of the interposed part body 15 are the engagement teeth 13 in the receiving recesses 12 formed on both sides of the base part body 1. Furthermore, connecting portions 14 are provided protruding inside the engaging teeth 13, 13, and these connecting portions 14 are inserted into the through hole portions 17 of the intervening body 15. The connector 18, which faces the connecting part 34 of the mounting bracket 3 and is inserted from both end surfaces of the intervening part body 15, is inserted into the screw hole 34a of the connecting part 34 through the through hole 14a of the connecting part 14. It is screwed in. As is clear from FIG. 3, the intervening body 15 has a symmetrical shape, and the base body 1 is attached to the vehicle body in the state shown in FIG. The direction can be changed appropriately by operation, and the standing angle with respect to the setting plane can be adjusted within the range of the virtual line shown in FIG.

To explain the operation of the device according to the present invention as described above, by releasing the tightening connection by the connector 18, a setting relationship can be established in which the setting angles of the base body 1, the intervening body 15, and the mounting bracket 3 are changed as appropriate. In other words, as shown in FIG. 2, the angle at which the base body 1 and the mounting bracket 3 are assembled can be varied. No matter what kind of slope the antenna 4 is set on, the antenna 4 can be installed vertically when viewed from the front (or back) of the vehicle body. Further, by pushing the push button body 6 against the elasticity of the elastic member 7, the engaging protrusion 81 that was engaged with the engaging part 21 as shown in FIG. 5 is released as shown in FIG. Moreover, the locking piece 84 is inserted into the insertion hole 1 of the base body 1.
