Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting tool for mounting an in-vehicle TV antenna on a vehicle equipped with a roof rail.

[0002]

[Prior art]

 In recent years, automobiles have become widely used not only as a means of transportation and transportation but also as a leisure tool such as camping, skiing and MTB touring. Demand for wagons and RVs (leisure vehicles) as vehicles suitable for such leisure is increasing.

[0003] To these RVs, a ski rack, a bicycle rack, and the like are easily mounted, and a roof rail is often mounted on the roof in order to visually emphasize the difference from a commercial vehicle. Normally, one roof rail is attached near the left and right edges of the roof.

Since the RV is mainly for leisure, an in-vehicle TV may be attached to meet the demand for watching TV even in the car. Since automobiles are moving while driving, it is difficult to constantly receive the TV radio waves clearly, and therefore a method of receiving radio waves through a diversity system has been developed. This diversity system uses multiple diversity antennas (usually 4) to receive, and the diversity unit installed in the vehicle automatically selects the one with the best reception among the radio waves received by the 4 antennas. And send it to the TV, so that you can always get the clearest picture possible even if the position or direction of travel of the car changes.

[0005]

[Problems to be solved by the device]

 When installing four diversity antennas, it is common to install one antenna set that can support two rod antennas in a V-shape at different angles, one on each side of the roof. . However, in the case of an automobile having a roof rail on the roof, the roof rail interferes and cannot be mounted in place. Therefore, each antenna set is attached to the inside of the roof rail or to the left and right of the rear hatch door.

However, when the antenna set is attached to the inside of the roof rail, the space between the antenna sets becomes narrow, and the antennas attached at an angle to the inside contact each other. Also, if it is attached to the hatch door, it will be difficult to receive because the attachment position will be low, and there is a danger that the tip of the antenna rod may hit your face when the hatch door is opened and closed. Therefore, there is a need for a mounting tool that can be used without a bearing to use a diversity antenna set even in a vehicle equipped with a roof rail.

[0007]

[Means for Solving the Problems]

 The antenna mount of the present invention is intended to mount an antenna set on the roof rail (1), and includes a main body (2) for supporting the antenna and a flexible metal attached to the main body (2). It has a fixed belt (3) consisting of a plate, a stop plate (4) attached to the end of the fixed belt, and a fastening member (7) for connecting the main body (2) and the stop plate (4). Is characterized by.

[0008]

[Action]

 The fixing belt (3) is wound around the roof rail (1), and the stop plate (4) provided at the tip of the fixing belt (3) and the main body (2) are fastened with a tightening bolt (7) as a fastening member. An annular part is formed by the main body (2), the fixing belt (3), the retaining plate (4), and the tightening bolt (7). By tightening the tightening bolt (7), the annular part becomes a roof rail (1 ) Will be tightened and the fixture supporting the antenna will be fixed to the roof rail (1).

[0009]

【Example】

 Since the fixture of the present invention is attached to each of the left and right roof rails at one place, the fixture for the left roof rail will be described in the embodiments with reference to the drawings. The configuration of the left and right fixtures is basically the same, but the shape is left-right symmetrical considering the antenna opening direction and the ease of tightening the screws of the fixtures.

FIG. 1 is a view showing a state in which the antenna mount of the present invention is mounted on a roof rail (1), and FIG. 2 is a view showing a mounting method of the antenna mount. Further, FIG. 3 is a front view of the state in which the attachment is attached.

The antenna mounting device of the present invention is attached to the main body (2) supporting the antenna, the fixed belt (3) made of a flexible metal plate attached to the main body, and the tip of the fixed belt (3). And a stop plate (4). The main body (2) is composed of an antenna part (2a) consisting of two rod antennas and a supporting part thereof, and a base part (2b) connected to a fixing belt. The fixing belt (3) is a flexible metal plate and maintains its shape even if the force is released by bending with light force.

When mounting on the roof rail (1), first the mounting position of the antenna is determined. It is preferable to wind an appropriate length of rubber sheet (5) around the mounting position and secure it with tape (6). This rubber sheet (5) allows the antenna fixture to be strongly tightened and secured to ensure fixation, prevents misalignment after attachment, and as a spacer when attaching to a roof rail with a small thickness. Has the effect of. Furthermore, it also serves to prevent the roof rail (1) from being scratched.

The main body (2), the fixing belt (3) and the stop plate (4) are wound around the roof rail (1) from above the rubber sheet (5). Insert a tightening bolt (7) of an appropriate length according to the thickness of the roof rail (1) through the washer (8) into the bolt through hole (2c) of the body (2), and then insert the body (2). Insert the tip of the bolt (7) into the bolt hole (4a) of the stop plate (4). A nut is attached to the bolt hole (4a) of the stop plate (4) (the screw hole may be screwed to match the bolt), so tighten the bolt (7) with a screwdriver. , The main body (2), the fixing belt (3), the retaining plate (4), and the annular part formed by the tightening bolt (7) tightens the roof rail (1), and the main body (2) and the roof rail (1). And are fixed. The tip of the bolt (7) that penetrated the bolt hole (4a) of the stop plate (4) was covered with a resin protective cap to prevent the roof from being scratched.

The above attachment is similarly performed for the right roof rail. After mounting the main body, wire the antenna and adjust the angle. The antenna can be changed in various lengths and angles as shown in (a), (b), and (c) of FIG. 4, so that even if there is a load on the roof carrier, avoid the luggage and extend the antenna. be able to.

The antenna part (2a) to which two antennas are attached can be detached from the base part (2b) by pushing the removal button (2d) and pulling it out as shown in FIG. This is to prevent damage when washing the car and to prevent theft when parking for a long time. After removing the antenna part (2a), the cover (9) for contact protection can be attached.

[0016]

[Effect of device]

 The diversity antenna can now be easily attached to the roof rail, so the antennas do not touch each other and are safe. In addition, since the mounting position is higher than the roof surface by the height of the roof rail, reception of radio waves will be better. Moreover, the antenna mounting part does not spoil the appearance of the car, which is aesthetically pleasing.
