本考案は、例えば自動車ラジオ或いは携帯用のラジオ、
テレビ等に使用するロッドアンテナの先端のトップ構造
に係り、特に充分な強度を有する構造に関するものであ
る。[Detailed description of the invention] The invention can be used, for example, in a car radio or a portable radio,
The present invention relates to a top structure at the tip of a rod antenna used for televisions, etc., and particularly to a structure having sufficient strength.
ロッドアンテナではアンテナ先端ポールに径の大きいト
ップが設けられ、このトップを指で摘んで操作するよう
になよっているので、トップ構造を考えるに当っては、
トップに回転力と引張力の２つの力が作用することを考
慮して設計しなければらない。In a rod antenna, a large-diameter top is provided on the antenna tip pole, and the top is operated by pinching it with your fingers, so when considering the top structure, consider the following:
The design must take into account that two forces, rotational force and tensile force, act on the top.
そこで従来は人間の指によるねじり力、引張力が実験に
よりは＞４ ｋｇ ７ｃｍであるので、安全率をみて８
ｋｇ／ｃｍ程度の強度を有するように、螺合或いはカシ
メにより一体的に固着されている。Therefore, conventionally, the twisting force and tensile force due to human fingers is >4 kg 7 cm according to experiments, so considering the safety factor, 8
They are integrally fixed by screwing or caulking so as to have a strength of approximately kg/cm.
螺合による場合はアンテナの先端ポールに螺子部を形成
してそこにトップを螺合し、この螺合による係合力で一
体化するものであるが、これによると引張力に対しては
強いが、ねじり回転によりゆるみを生じやすい。In the case of screwing, a threaded part is formed on the tip pole of the antenna, and the top is screwed into it, and the engagement force generated by this threading is used to integrate the antenna, although it is strong against tensile forces. , easy to loosen due to twisting rotation.
特にトップを合成樹脂で作つた際には螺合による締付は
力が比較的弱いため、長期の使用において徐々にゆるみ
はじめたり、衝撃的な引張力（衣服等でトップを引掛け
てしまうような場合）が作用してトップが抜は飛ぶこと
があった。In particular, when the top is made of synthetic resin, the tightening force by screwing is relatively weak, so it may gradually start to loosen after long-term use, or there may be an impactful tensile force (which may cause the top to get caught on clothing, etc.). In some cases, the top position could be overtaken due to the above.
またカシメによる場合はトップを被装した後にそのトッ
プの途中或いは他部を押つぶすものであるが、これによ
ると段が付いて外観の見栄えが悪くなり、多段の他の段
と見誤ることがあって好ましくない。In addition, in the case of caulking, after the top is covered, the middle or other parts of the top are crushed, but this creates a step that looks bad and can be mistaken for another step in a multi-step structure. I don't like it.
本考案はこのような事情に鑑み、アンテナ全体の組立工
程順を考慮してトップを螺合係合等により一体化するが
、回転力が加わってもゆるまないようにし、且つ強大な
引張力に対しても抜けないように改良したもので、この
ためアンテナの先端ポールに小径部を形成して、この部
分に取付金具を引抜きは阻止するが回転は自在に取付け
、このような取付金具にトップを固着するようにしたロ
ッドアンテナのトップ構造を提供するものである。In view of these circumstances, the present invention integrates the top by threaded engagement, etc., taking into account the order of the assembly process of the entire antenna, but also prevents it from loosening even when rotational force is applied, and is designed to be able to withstand strong tensile force. For this reason, a small diameter part is formed on the tip pole of the antenna, and the mounting bracket is attached to this part to prevent it from being pulled out, but to allow it to rotate freely. The present invention provides a top structure for a rod antenna to which the antenna is fixed.
以下、図面を参照して本考案の実施例を具体的に説明す
る。Embodiments of the present invention will be specifically described below with reference to the drawings.
第１図の第１の実施例についてまず説明すると、符号１
はアンテナの先端ポールであり、このアンテナの先端ポ
ール１の端部手前に円周上段を付けて溝を切ることによ
り小径部２が形成され、この小径部２の付近に取付金具
３が取付けられる。First, the first embodiment shown in FIG. 1 will be explained.
is the tip pole of the antenna, and a small diameter portion 2 is formed by adding a circumferential upper step to the front of the end of the antenna tip pole 1 and cutting a groove, and a mounting bracket 3 is attached near this small diameter portion 2. .
取付金具３は第１図すのように筒状に形成されて下側は
Ｓ゛半分螺子部３ａになっていてその上側半分が小径の
円筒部３ｂとなり、内部にはアンテナの先端ポール１と
はＳ゛同一径の孔４が穿孔されており、更に螺子部３ａ
の端部に治具を挿入するための溝５が設けられている。The mounting bracket 3 is formed into a cylindrical shape as shown in Fig. 1, and the lower side is an S half screw part 3a, the upper half is a small diameter cylindrical part 3b, and the inside has the tip pole 1 of the antenna. A hole 4 of the same diameter S is bored, and a threaded portion 3a
A groove 5 for inserting a jig is provided at the end of the groove.
そこで組立時アンテナの先端ポール１に取付金具３を嵌
込み、その後取付金具３の円筒部３ｂの小径部２と対応
する左右の２個所を外側からつぶしこのとき金具内側に
突出した部分６を第１図ａのように小径部２に入れて係
合するものであり、これにより取付金具３は回転自在に
抜は止めされる。Therefore, when assembling, the mounting bracket 3 is fitted into the tip pole 1 of the antenna, and then the two places on the left and right sides corresponding to the small diameter part 2 of the cylindrical part 3b of the mounting bracket 3 are crushed from the outside. As shown in Figure 1a, it is inserted into the small diameter portion 2 and engaged, thereby preventing the mounting bracket 3 from being removed while being rotatable.
こうして取付金具３が取付けられた後その一端の溝５に
治具を差込んで動かないように固定した状態で、合或樹
脂或いは金属のトップ７を被ぶせ且つ螺子部３ａで螺合
して一体結合するものである。After the mounting bracket 3 is installed in this way, the jig is inserted into the groove 5 at one end and fixed so that it does not move, and then the top 7 made of resin or metal is covered and screwed together with the screw part 3a. It is an integral part.
かくして、アンテナの先端ポール１に対し小径部２と突
出した部分６との係合で引抜きは阻止するが回転は自在
に取付けられた取付金具３にトップ７が螺合して固着さ
れるので、トップ７の引張力は小径部２と突出した部分
６との係合力により強大なものになり、試験によると２
０ｋｇ／ｃｍにも耐え得る。In this way, the top 7 is screwed and fixed to the mounting bracket 3 which is attached to the tip pole 1 of the antenna so that the small diameter part 2 and the protruding part 6 are engaged with each other to prevent the antenna from being pulled out but to be freely rotatable. The tensile force of the top 7 becomes strong due to the engagement force between the small diameter part 2 and the protruding part 6, and according to tests, the tensile force is 2.
It can withstand even 0 kg/cm.
また取付金具３と共にトップ７は回転が自在であるので
、トップ７にねじり回転力が作用すると取付金具３も一
緒に回って両者の間にそのねじり力が作用しなくなる。Further, since the top 7 is rotatable together with the mounting bracket 3, when a torsional rotational force is applied to the top 7, the mounting bracket 3 is also rotated together, and the torsional force is no longer applied between the two.
次いで第２図の第２の実施例によると、この場合は取付
金具３の構造が上述と異なっており、同一外径の螺子部

ンテナの先端ポール１の小径部２に係合し、取付金具３
の全域にトップ７を螺合するようになっている。Next, according to the second embodiment shown in FIG. 2, in this case, the structure of the mounting bracket 3 is different from that described above, and there is only a threaded portion 3a having the same outer diameter, and a groove 8 is formed on the outer periphery of the threaded portion 3a. is formed, crush the groove 8, engage the protruding part 6 with the small diameter part 2 of the tip pole 1 of the antenna, and attach the mounting bracket 3.
The top 7 is screwed into the entire area.
尚、取付金具３においてつぶす場合には、局部的に複数
個所のみならず全周に沿って行つＣも良く、螺子部３ａ
の配置はどのようにしても良い。In addition, when crushing the mounting bracket 3, it is good to do it not only locally in multiple places but also along the entire circumference, and the threaded part 3a
may be arranged in any way.
更に第３図の第３の実施例によると、トップ７の構成が
上述と異なっている。Furthermore, according to the third embodiment shown in FIG. 3, the structure of the top 7 is different from that described above.
即ち取付金具３は外周に螺子を設ける必要がなく円筒部
３ｂにされ、このような取付金具３の上に合成樹脂のト
ップ７を熱成形して被装するものであり、このとき取付
金具３のつぶしによりできた凹部９に樹脂の一部分１０
が注入して一体的に係合する。That is, the mounting bracket 3 is made into a cylindrical portion 3b without the need to provide a screw on the outer periphery, and the top 7 of synthetic resin is thermoformed and covered on the mounting bracket 3. At this time, the mounting bracket 3 A portion of the resin 10 is placed in the recess 9 created by crushing the resin.
are injected and integrally engaged.
従ってこの実施例では上述の実施例によりトップ７が取
付金具３に堅固に固定される。Therefore, in this embodiment, the top 7 is firmly fixed to the mounting bracket 3 according to the embodiment described above.
また取付金具３の外表面にローレットや溝を設けると、
トップ７の樹脂との結合が強固になる。Also, if knurling or grooves are provided on the outer surface of the mounting bracket 3,
The bond with the top 7 resin becomes stronger.
以上説明したように本考案によると、先ず先端ポールに

おいて都合が良い。As explained above, according to the present invention, first, a stepped small diameter part is formed on the tip pole, a metal fitting is fitted onto this, and after the fitting, a part of the mounting fitting is crushed to form the small diameter part. This is convenient in the process of assembling the entire antenna, as the process is completed by making a hook for the antenna and finally screwing the top 7 together.
トップ７は強大な引張力を有し且つねじり回転力による
ゆるみを生じなくなるので、寿命が著しく増す。Since the top 7 has a strong tensile force and does not loosen due to torsional rotational force, its life is significantly increased.
更につぶしたあとが表に出ないので、外観の悪化が防止
される。Furthermore, since the crushing marks are not visible, deterioration of the appearance is prevented.
