Description

Description: TECHNICAL FIELD The present invention relates to a vehicle antenna support for mounting a vehicle antenna on a vehicle of an automobile.

In general, a vehicle antenna is mounted in a state of being highly projected from the vehicle. Therefore, for example, when the vehicle is put in a garage, it is required that the antenna be tilted with respect to the vehicle.

Therefore, conventionally, the base frame having the mounting portion for the vehicle is
A rotating frame having an antenna fixing portion for fixing the antenna is tiltably pivoted, and the antenna fixed to the antenna fixing portion is tilted in a plane parallel to the tilting surface of the rotating frame. And an operating lever having an engaging body at one end thereof is provided on a part of the rotating frame, while the base frame is provided at an arbitrary tilt position of the rotating frame with respect to the base frame. There is provided a vehicle antenna supporting tool provided with an engaging portion adapted to engage the engaging body (see, for example, Japanese Utility Model Laid-Open No. 57-98006). However, the above-mentioned engaging portion is a gear-like member arranged in a direction parallel to the tilting surface of the rotating frame. Further, both the operating lever and the engaging body provided at the lower end of the operating lever swing in a plane parallel to the tilting plane.

Therefore, in a normal condition, a part of the engaging body is always in mesh with the bottom of the gear, and the condition is good. On the other hand, when a car runs on a rough road, the antenna vibrates back and forth, and its inertia strongly urges the rotating frame toward the tilting surface. Then, the engaging body also receives a force in the direction of the tilting surface of the rotating frame, and the engaging part floats up from the valley of the gear toward the mountain, disengages, and the antenna suddenly falls during running. There is a point. For this reason, a strong "spring" is attached to the engaging body so as to face the above-mentioned strong force. Then, the above problems can be solved. However, when the spring force is increased, it is difficult to operate with the grip force of women and girls, and there is a problem that it is difficult to commercialize.

In addition, if you double the tilt of the antenna to the side with the operating lever, the entire weight of the tilted antenna is added to the operating lever, and you can lift the antenna from the operating lever with one hand to perform stop operation. However, there is a problem that both hands are required, and it has been desired to provide a configuration that can be operated with one hand.

Therefore, the present invention has a technical problem to solve the above-mentioned problems, and it is possible to support the antenna so that the antenna can be tilted up and down with respect to the vehicle, and further, lock the respective states in the standing state or the tilted state. A vehicle antenna support that can maintain that state, and even if it has such a locking mechanism, it can be operated with one touch when tilting the antenna. It is intended to provide the ingredients.

Next, 31 is an engaging body provided on the rotating frame 21, which is an engaging portion of the base frame body 7.
It can be engaged and disengaged with respect to 17. This engaging body 31 has a chrysanthemum shape whose front shape corresponds to that of the engaging portion 17 as shown so that the rotating frame 21 can engage with the engaging portion 17 at an arbitrary tilted position with respect to the base frame 6. And is supported by the support arm 32. The base portion 33 of the support arm 32 is pivotally attached to the rotary frame 21 by a pivot pin 34. Further, a spring 37 is interposed between the base portion 33 and the rotating frame 21 so that the engaging body 31 is always biased in the direction of engaging with the engaging portion 17. Reference numerals 35 and 36 denote spring positioning pieces. 3
Reference numeral 8 denotes an operation lever, which is formed integrally with the support arm 32. Further, the operation lever 38 is arranged so as to be in a state along the planned existence position of the base portion 5a of the antenna 5 which is fixed to the antenna fixing portion 40. It is arranged. The antenna fixing portion 40 is composed of a connector seat screwed to the connecting plate 23. Reference numeral 41 is a coaxial cable connected to the above-mentioned connector seat (antenna stop portion 40). One end thereof has a central conductor 41a as the center conductor 40a in the antenna stop portion 40 and an outer conductor 41b as an antenna as shown in FIG. They are connected to the outer conductors 40b of the fastening portions, respectively. The other end is connected to a wireless device in the automobile 1 through a space 18 and an insertion hole 19.

In the supporting tool having the above-mentioned structure, the rotating frame 21 is put on the base frame body 7 from above in FIG. 5, and the rear pivot shaft 27, the engaging body 31, the operating lever 38 and the like are attached to the support frame body. It is assembled by mounting the mounting frame 9 to the 7. The above-mentioned assembly may be performed in another order.

Next, when using the support 4, the mounting portion 8 is first mounted on the roof side 3 of the vehicle. After that, the connector provided on the base portion 5a of the antenna 5 is screwed to the antenna fixing portion 40, and the antenna 5 is attached to the support tool 4.

When transmitting and receiving in the above state, the antenna 5 is generally used in an upright state as shown in FIG.

On the other hand, when it is desired to weaken the wind hitting the antenna 5 when the vehicle 1 is put in a garage or when traveling, the antenna 5 is tilted with respect to the vehicle 1. To perform this operation, first grasp the antenna base 5a and the operating lever 38 with the palm 42 as shown in FIG.
Tilt 38 in the direction of arrow 43. As a result, the engaging body 31 is disengaged from the engaging portion 17 in the arrow 43 'direction. In this state, there is nothing to prevent the rotation of the rotation frame 21 with respect to the base frame 6, so that the antenna 5 can be moved to the arrow 44 in FIG. It can be tilted in any direction indicated by 45. In this case, the 8th
As shown in the figure, the rotating frame 21 tilts with respect to the base frame 6 while the guide surface 25 of the rotating frame 21 is guided along the guide surface 15 of the base frame 6. When the antenna 5 is tilted to the desired angle in this way, the palm 42 is released at that position. Then, the operating lever 38 is returned to the position shown in FIG. 6 by the urging force of the spring 37, and the engaging body 31 engages with the engaging portion 17. As a result, the antenna 5 is held as it is in the tilted state.

When tilting the antenna 5 in the directions of the arrows 44 and 45 as described above, the base frame main body 7 has a large space 18 for storing the cable.
Since the space is formed, the cable 41 can freely bend in the space. Therefore, the cable 41 is prevented from being caught at any place and being cut.

When engaging the engaging body 31 with the engaging portion 17 after the tilting operation as described above, the opening edge of the concave engaging portion 17 and the tip of the engaging body 31 have a smooth rounded shape. Therefore, even if the engaging body 31 and the engaging portion 17 are not properly opposed to each other, the engaging body 31 is fitted into the engaging portion 17 in a sliding manner to achieve the engagement between them.

Next, FIGS. 10 and 11 showing a different embodiment of the present application will be described. These figures show different examples of the structure of the attachment part to the vehicle, and show the structure that can be attached to the trunk of the vehicle.In the figures, 51 is a mounting plate, A cushioning member (elastic member) 52 made of rubber or the like is joined over the entire surface. Reference numeral 53 denotes an overhanging piece on the mounting plate 51. 54 is a facing piece, to which a fixing screw 55 is screwed. 56 and 56 are a pair of rising pieces, between which the lower portion of the base frame body is interveningly mounted.

As shown in FIG. 11, the above-mentioned structure is obtained by placing the mounting plate 51 on the trunk 58 of the automobile and pressing the tip of the fixing screw 55 provided on the lower surface side thereof to the lower surface of the trunk lid 58. , Is mounted on the vehicle. In this case, the tip end of the overhanging piece 53 contacts the vehicle body 58 'of the automobile, and the mounting state of the mounting plate 51 becomes extremely stable.

In addition, parts that are considered to be the same or equivalent in configuration to those in the previous figure in terms of function are denoted by the same reference numerals as those in the previous figure with the letter e added to omit redundant description. (Also, in the following figures and the like, alphabetical letters f and g are sequentially given in order to omit the duplicated description.) Next, FIG. 12 shows the engagement portion in the base frame and the engagement in the rotating frame. It shows an example in which the respective structures of the coalescence are different. It suffices that the engaging portion and the engaging body are engaged with each other so that the rotation of the rotating frame with respect to the base frame is blocked. As shown in FIG. 12, the engaging portion 17f is provided. To form a protrusion,
The engagement body 31f may be formed in a concave shape.

Next, FIGS. 13 and 14 show still another embodiment of the present application, in which the engaging portion 17g is composed of a large number of engaging elements 17ag arranged along the edge of the base frame main body 7g,
On the other hand, the engaging body 31g provided on the rotating frame 21g can be engaged with the engaging element 17ag of the engaging portion 17g at an arbitrary position.

When the antenna having the above-mentioned structure is to be tilted up and down, the operating portion 38g is moved in the direction of the arrow 43g in the same manner as the above-mentioned case so that the engaging portion 31g is moved to the arrow 43'g.
It moves in the direction and disengages from the engaging portion 17g. In this state, the tilting operation of the antenna is performed as described above, and if the lever 38g is then released, the engaging body 31g again engages with the engaging portion 17g.
And the rotation of the rotation frame with respect to the base frame is blocked.

As described above, according to the present invention, the rotating frame with respect to the base frame 6
When the antenna 5 is desired to be tilted up and down, since the tilting 21 is pivotally attached, it is possible to achieve the intended purpose simply by tilting the rotating frame 21 with respect to the base frame 6.

Moreover, since the base frame 6 and the rotary frame 21 are respectively provided with the engaging portion 17 and the engaging body 31 that can be engaged with each other, the effect that the antenna 5 can be maintained in the standing or tilted position. There is also.

Further, in the invention of the present application, even with the configuration capable of exhibiting the above-described two excellent effects, the engagement body 31 is not attached to the tilting surface of the rotating frame 21 with respect to the engagement portion 17. Since it is a configuration that allows it to freely move back and forth in the direction of intersection, the antenna vibrates back and forth when the car is traveling on a rough road, and even if the inertia of the antenna strongly urges the rotating frame in the tilting surface direction, Since the engaging body 31 does not move in the direction parallel to the tilting surface of the rotating frame 21, it has a feature that the rotation of the rotating frame 21 is firmly held and the established state of the antenna 5 is maintained. In addition, in the above situation, the engaging body 31 is immovable, and even if the engaging body 31 has a rigid structure that can withstand a large biasing force, the engaging body 31 is only retracted laterally from the engaging portion 17 when adjusting the tilt of the antenna. Since it is good, a little power is enough. This produces usefulness that women and women can easily operate.

In addition, in the present invention, even when the engaging body 31 is engaged with the engaging portion 17 as described above, the operating lever 38 for operating the engagement and disengagement of the engaging body 31 tilts the rotating frame 21. Since it can freely move back and forth in the direction intersecting with the plane and is arranged at a position along the base portion 5a of the antenna 5, when performing the above-mentioned tilting operation, the palm is operated as shown in FIG. It has a feature that both sides of the base portion 5a of the antenna 5 can be supported by the thumb and the remaining four fingers even when the lever 5 is in contact with the lever 38.

This means that it is possible to control with one hand the two movements of moving the operation lever 38 forward and backward toward the rotary frame 21 and moving the antenna 5 in the direction parallel to the rotary surface of the rotary frame 21. There is an epoch-making effect that the left and right tilting operation of the antenna and the operation of advancing and retracting the engaging body 31 to fix and disengage the engaging body 31 can be easily performed with one hand and in a one-touch manner.
