Description

[Detailed Description of the Invention] The present invention relates to a rod antenna attachment for automobiles, portable radios, televisions, etc., and particularly relates to a rod antenna attachment for fixing a guide pipe that accommodates the rod in a drawable manner. be.

In general, cars or portable radios, televisions, etc.
Equipped with a rod antenna that can be pulled out when in use.
This rod antenna is retractably housed inside the hood or inside a guide pipe fixed to the casing.

That is, as shown in FIG. 1, a cylindrical guide pipe 4 is fixed to a fixing member 2 in a bonnet or casing 1 via a fixture 3, and a telescoping multi-stage rod is inserted into this guide pipe 4. 5 is housed so as to be freely drawn out, and a decorative ball 6 is attached to the tip of the topmost rod 5a.

The fixture 3 has two fastening pieces 3a and 3b stacked one on top of the other to form a fastening part 3C for the guide pipe 4 at the end thereof.

However, when fixing the guide pipe 4 to the fixing member 2 using such a fixture 3, while holding the guide pipe 4 with one hand, overlap the two fastening pieces 3a and 3b, and tighten the screw 7.
, 7 to the fixing member 2, it is difficult to install the guide pipe 4, and furthermore, when a strong force in the direction of arrow A is applied to the guide pipe 4, both the clamping pieces at the clamping part 3c There was a drawback that the slit 8 formed between the tips of the parts 3at and 3b opened and the guide pipe 4 could be pulled out from the fastening part 3c.

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a rod antenna mounting tool that facilitates the installation work of a guide pipe and allows the guide pipe to be securely fastened to a fixing member.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 2 and 3.

Note that the same parts as in FIG. 1 are given the same reference numerals.

In FIG. 2, a fitting 10 according to the present invention has a cylindrical shape that fits around the outer peripheral surface of a guide pipe 4, and has a slit window 19 located at the center in the length direction and extending in the circumferential direction. The fastening cylinder part 11 has a part of its circumference where the slit window 19 is not formed, which is separated in the axial direction to form a separated part (slit) 12.

The separation part 12 is provided with mating pieces 13 and 14 extending parallel to each other in the radial direction, and a support plate part 15 is integrally provided at the lower end of one of the mating pieces 14 in a direction perpendicular thereto. This support plate portion 15 is fixed to a suitable fixing member 16 with screws 17.

Further, a fastening plate 18 as shown in FIG. 3 is attached to the lower side of this support plate portion 15, and this fastening plate 18 has an inclined surface 18a at one end. The other end of the waist fastening plate 18 that engages with the free end of the portion 15 is bent at a right angle to form a bent portion 18b, which is engaged with the lower end portion of the mating piece 13.

Regulating protrusions 15a, 15a are suspended from both sides of the support plate portion 15 to prevent the fastening plate 18 from shifting left and right, and the free end of the support plate portion 15 has a sloped surface of the fastening plate that is arranged horizontally. The inclined surface receiving portion 15b is formed so as not to shift.

Further, the fastening plate 18 has a long hole 1 for inserting the screw 17.
8c, the screw insertion hole 15c is the elongated hole 18 in the support plate part 15.
The screws 17 are inserted into the fixing member 16 by passing through the elongated holes 18c and the screw insertion holes 15c.
It is configured to be screwed onto the

In such a configuration, the screw 17 is tightened and the fastening plate 18
When the support plate 15 is brought close to the support plate 15, the inclined surface 18a slides on the free end of the support plate and rises obliquely.

Then, the fastening plate 18 is moved in the extending direction of the support plate portion 15 (arrow B
direction), and the bent portion 18b brings the mating piece 13 close to the mating piece 14 opposite thereto, so that the fastening cylindrical portion 1
1 will tighten the guide pipe 4.

Therefore, when installing the guide pipe 4, first, the engaging protrusion 20, which is stamped and molded from the inside at a predetermined location of the guide pipe 4, is positioned within the slit window 19 of the fastening cylinder part 11. The guide pipe 4 is held within the tightening tube 11, and the screw 17 is tightened to the fixing member 16.

At this time, even if the fastening cylinder part 11 is loosely fitted into the guide pipe 4, the guide pipe 4 is prevented from falling downward as the engaging protrusion 20 engages with the slit window 19. .

In addition, the slit window 19 and the guide pipe 4 are connected to the engagement protrusion 20.
The holes are sized so that they can be moved up and down a predetermined amount, so
When attaching the fixture 10 to the fixing member 16, the relative positional relationship between the guide pipe 4 and the fixture 10 can be finely adjusted.

Furthermore, the elastic force of the tightening cylinder portion 11 is doubled due to the presence of the slit window 19, and the tightness of the screw 17 to the guide pipe 4 increases when the screw 17 is tightened.

In this way, when installing the guide pipe 4, the screw 17
Since it is only necessary to tighten the guide pipe 4, there is no need to hold the guide pipe 4 with one hand so that it does not fall down.
Due to the elastic force of the fastening cylinder portion 11 that causes the mating piece 13 to separate from the mating piece 14, the second
Since the guide pipe 4 can be attached to the support plate part 15 in the state shown in the figure, it is easy to attach the guide pipe 4.

Furthermore, in this embodiment, since the guide pipe 4 is firmly fixed to the clamping cylinder part 11, even if a strong lateral force is applied to the guide pipe 4, the guide pipe 4 can be firmly fixed to the clamping cylinder part 11, unlike the conventional one. There is no fear that the guide pipe 4 will come out.

Note that the fastening plate 18 formed separately from the fixture 10 in this embodiment may be formed integrally and continuously under the mating piece 13 of the fixture 10 without providing the bent portion 18b. , in this way, the fastening plate 18 and the support plate part 15
The movement of contact and separation on the free end side is transmitted to the upper end of the mating piece 13, 14 using the lower end as a fulcrum, and the screw 1
7, the upper ends of the mating pieces 13 and 14 open.

As a result, the clamping cylinder part 11 cannot clamp the guide pipe 4 on its entire circumferential surface, and the guide pipe 4 cannot be expected to be reliably held and fixed.

Therefore, if the fastening plate 18 is configured separately from the mating piece 13 as in this embodiment, or if the fastening plate 18 is integrated with the mating piece 13, the support plate portion 15 which is integrated with the mating piece 14 is provided. It is separated from the mating piece 14 to form a separate body, and a bent part similar to that formed on the fastening plate 18 is formed at the end on the mating piece 14 side, and the mating piece 14 is pressed by this bent part. It is most preferable to do so.

As explained above, the rod antenna mounting part of the present invention is
With the structure described above, when the guide pipe 4 is attached to the fastening cylinder part 11, when the support plate part 15 and the fastening plate 18 are brought close to each other with the screws 17, the fastening plate 18 moves and the mating piece 1
3 to the mating piece 14 side, narrowing the gap between the separated parts 12, and uniformly tightening and fixing the guide pipe 4 on the entire inner circumferential surface of the fastening cylinder part 11, firmly and reliably fixing the guide pipe 4. Hold.

Moreover, by loosening the screw 17, the tightening of the guide pipe 4 of the tightening cylinder part 11 is released, and the guide pipe 4 can be moved or removed, and the fixture can be used any number of times.
