Description

【考案の詳細な説明】 1)産業上の利用分野 この考案は自動車用アンテナの盗難防止警報装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION 1) Field of Industrial Application This invention relates to an antitheft alarm device for an automobile antenna.

2)従来の技術 従来,自動車用アンテナの構造は車体に取付けたアンテナ基台にロッドをねじ こんだ形のまま使用されており,盗人はロッドをねじ回して抜き簡単に持ち去る ことができた。2) Conventional technology Conventionally, the structure of an antenna for an automobile has been used with the rod screwed into the antenna base mounted on the vehicle body, and a thief could screw the rod in and take it out easily.

この種の被害はかなり多く発生しておりその防止対策が望まれていた。 A considerable amount of this type of damage has occurred, and measures to prevent it have been desired.

3)考案で解決しようとする課題 この考案で解決しようとする物はアンテナロッドの底部が少しでもロッド受金 具の台座から離れると電気接点がオープンの状態となり,警報装置が働くような 工夫をする事である。3) Problems to be solved by the device The device to be solved by the device is such that the electrical contact becomes open when the bottom of the antenna rod is separated from the pedestal of the rod receiving tool even a little, and the alarm device works. Is to do.

4)課題を解決するための手段 この考案では第1図に示すように,ロッド差込みネヂ(2)の外周に円弧状の パターン(12)(13)を検出用接点電極としたドーナッツ状基板(3)をは めこみ,上からロッド(1)をねじこみ台座(5)に固定した状態が基本であり ,この状態では接点用電極(12)(13)はショートされた状態となっており 警報器は働らかない。4) Means for Solving the Problems In this invention, as shown in FIG. 1, a donut-shaped substrate (arc) having arc-shaped patterns (12) and (13) on the outer periphery of a rod insertion screw (2) as contact electrodes for detection ( 3) is inserted, and the rod (1) is screwed in from above and fixed to the pedestal (5). In this state, the contact electrodes (12) (13) are short-circuited. The vessel does not work.

尚,接点電極(12)(13)はリード線(8)によって警報器本体に接続さ れる。本体(7)の内部には第2図に示す周知の電子回路をもつ基板とスピーカ ー(16)等が装置されている。 The contact electrodes (12) and (13) are connected to the alarm body by the lead wire (8). Inside the main body (7), a substrate having a well-known electronic circuit shown in FIG. 2, a speaker (16) and the like are installed.

また,この電源は車のバッテリーから電線(9)を介して本体(7)に供給さ れる。 This power is also supplied to the main body (7) from the car battery via the electric wire (9).

5)作用 この考案によるアンテナのロッド(1)を盗みとろうとしてロッドを回すとネ ヂの作用で今までロッド(1)の底部でショートされていた接点電極(12)と (13)はオープンの状態となり,本体(7)内部の電子回路が働らきスピーカ ー(16)をピーピーと鳴らして警報する仕組みとなつている。5) Function When the rod (1) of the antenna according to the present invention is stealed to steal the rod (1), the contact electrodes (12) and (13), which have been short-circuited at the bottom of the rod (1) until now, are opened by the action of the rod. In this state, the electronic circuit inside the main body (7) is activated and the speaker (16) beeps to give an alarm.

尚,アンテナを台座ごと盗もうとして接点用リード線(8)を切断すれば,接 点がオープンの状態になったのと同じ原理で警報を鳴らす事となる。 If the contact lead wire (8) is cut in an attempt to steal the antenna together with the pedestal, the alarm will sound according to the same principle as when the contact was opened.

6)考案の実施例 以下本案の実施例について説明す。6) Embodiments of the Invention Embodiments of the present invention will be described below.

(イ)アンテナロッド(1)の離脱を検出するための接点電極(12)(13) を円弧状にパターン化したドーナッツ状基板(3)を作成する。これを第3図に 示す。(A) A donut-shaped substrate (3) in which contact electrodes (12) (13) for detecting detachment of the antenna rod (1) are patterned in an arc shape is prepared. This is shown in FIG.

(ロ)前記の基板(3)を受台座(5)のネヂ(2)にはめこんだ後ロッド(1 )を上からねじこみ,受台座(5)との間に完全に固定する。(B) After the substrate (3) is fitted into the screw (2) of the pedestal (5), the rod (1) is screwed in from above to completely fix it to the pedestal (5).

(ハ)接点電極(12)(13)はリード線(8)で警報器本体(7)の内部に セットされている電子回路に接続される (ニ)この装置の電源は車のバッテリーを用い電線(9)から供給される。(C) The contact electrodes (12) and (13) are connected to the electronic circuit set inside the alarm body (7) by the lead wire (8). (D) The power source of this device is a car battery. It is supplied from the electric wire (9).

本考案は以上のような構造であり第1図と第2図にその内容が示されている。The present invention has the structure as described above, and its contents are shown in FIGS. 1 and 2.

7)考案の効果 本考案の装置を実地に車に装備したのちアンテナロッド(1)を1回転でも緩 めると忽ちピーピーと言う警報音を発し,その効果は抜群であった。又,アンテ ナを台座ごと外しリード線(8)を切断するときも同様の効果が得られた。7) Effect of the device After the device of the present invention was installed in a vehicle and the antenna rod (1) was loosened even one revolution, an audible beep sound was emitted and the effect was outstanding. The same effect was obtained when the pedestal was removed from the antenna and the lead wire (8) was cut.

尚,警報音の継続時間は任意に設定できバッテリーがあがることはない。 The duration of the alarm sound can be set arbitrarily and the battery will not run out.
