【０００３】
【発明が解決しようとする課題】
上記構成の侵入警戒装置では、警戒装置本体２が住宅の外側に設置されているので、室内から切替スイッチＳＷを操作して警報状態と非警報状態とを切り替えることができなかった。また、警戒装置本体２が住宅の外側に設置されているため、侵入者によって警戒装置本体２が破壊される虞があり、警戒装置本体２が破壊されると、警報を発することができなくなるという問題もあった。
【０００４】
本発明は上記問題点に鑑みて為されたものであり、その目的とするところは、屋内から警報状態と非警報状態とを切り替えることができ、万一屋外に設置された部分が破壊されたとしても警報を発することができる侵入警戒装置を提供することにある。
【０００５】

請求項２の発明では、請求項１の発明において、警報発生部は、センサ部が接続される入力端子間が開放状態となることからセンサ部の破壊を検出して警報発生手段から警報を発生させることを特徴とし、センサ部が接続される入力端子間が開放状態となることからセンサ部の破壊を検出して、警戒装置本体より警報を発生させることができる。
【０００６】

【０００８】
請求項５の発明では、請求項１又は２の発明において、上記開閉部材は窓枠内に開閉自在に取り付けられた窓板であることを特徴とし、窓からの侵入者を検出することができる。

【００１２】
【発明の実施の形態】
本発明の実施の形態を図１乃至図４を参照して説明する。この侵入警戒装置は、図１及び図２に示すように、扉枠２３（建物の開口部）内に開閉自在に設置された玄関扉２０（開閉部材）の外側に取り付けられ、人体から放射される熱線を検出することにより、玄関扉２０の外側に設けた検知領域１ａにおける人の存否を検出する焦電素子のような人感センサ１（センサ部）と、玄関扉２０の内側に取り付けられる警戒装置本体２と、略Ｕ字状に形成され両側片３ｂ，３ｃの先端部にそれぞれ人感センサ１及び警戒装置本体２が取り付けられた連結部３とで構成され、人感センサ１を屋外側、警戒装置本体２を屋内側とし、連結部３の中央片３ａを玄関扉２０の上端部に載置するようにして玄関扉２０に取り付けられる。
【００１３】
また、図３はこの侵入警戒装置のブロック図を示しており、警戒装置本体２の内部には、スピーカＳＰと、玄関扉２０に設けられた来客確認用の覗き窓２０ａに向けて光Ｌ１を照射するランプＬ（投光部）と、後述の制御回路８から入力される点灯制御信号に応じてランプＬを点灯させる照明駆動回路４と、制御回路８から入力されるリレー駆動信号に応じてリレーコイル（図示せず）を励磁するリレー駆動回路５と、外部接続端子ｔ１，ｔ２間に接続されリレーコイルの励磁／非励磁に応じて開閉するリレー接点６と、制御回路８から入力される無線送信信号に応じて電波信号で警報信号を送信する無線回路７（ワイヤレス送信部）と、例えばマイクロコンピュータからなり人感センサ１の検出信号に応じて各部の動作を制御する制御回路８と、警戒装置本体２の１側面に配置され制御回路８の動作を警戒状態と非警戒状態とに切り替える切替スイッチＳＷ（動作切換部）と、電池９と、電池９を電源として各部の動作電源を生成する安定化電源１０とを収納してある。ここに、リレー駆動回路５とリレー接点６とで、外部に接点信号を出力する接点信号出力部が構成される。
【００１４】
ここで、この侵入警戒装置の動作を簡単に説明する。切替スイッチＳＷにより警戒状態に切り替えた状態で、図４に示すように不審者Ａが外部から玄関に近付いてくると、人感センサ１が不審者Ａを検出して、人体検知信号を制御回路８に出力し、警報発生部としての制御回路８は人体検知信号に応じてスピーカＳＰより警報音や生活音（例えば人の声やメロディ音や電話の音など）を鳴らして、侵入者を威嚇したり、住宅内に人がいると錯覚させる。この時同時に制御回路８は照明駆動回路４によりランプＬを点灯させており、覗き窓２０ａを通して玄関の照明が点灯したように見せかけ、内部に人がいると不審者Ａに錯覚させる。また同時に、制御回路８は、リレー駆動信号をリレー駆動回路５に出力するとともに、無線送信信号を無線回路７に出力しており、リレー駆動回路５がリレー駆動信号に応じてリレー接点をオン又はオフさせることによって、外部接続端子ｔ１，ｔ２に接続された外部機器に対して接点信号を出力することができ、また無線回路７が無線送信信号に応じて電波信号で警報信号を送信することによって、侵入者の検知状況を遠隔から監視することができる。
【００１５】
このように、本実施形態の侵入警戒装置は、人感センサ１を玄関扉２０の屋外側、警戒装置本体２を玄関扉２０の屋内側とし、連結部３の中央片３ａを玄関扉２０と扉枠２３との間の隙間に配置するようにして玄関扉２０に取り付けており、屋内に配置される警戒装置本体２に切替スイッチＳＷを設けているので、屋内から切替スイッチＳＷを操作して、警戒状態と非警戒状態とを切り替えることができる。また、屋外側に設置された人感センサ１が破壊されたとしても、屋内側に設置された警戒装置本体２は無事なので、例えば人感センサ１が接続される制御回路８の入力端子間が開放状態となるのを検出することによって、制御回路８がスピーカＳＰなどから警報を発生させることができる。
【００１６】
ところで、本実施形態では侵入警戒装置を玄関扉２０に取り付けた場合を例にして説明を行ったが、侵入警戒装置の設置部位を玄関扉２０に限定する趣旨のものではなく、建物の外壁に設けた開口部に開閉自在に設置された開閉部材であれば玄関扉２０以外の部材（例えば窓板など）でも良く、例えば図５（ａ）（ｂ）に示すように、開口部としての窓枠２１内に開閉自在に取り付けられた開閉部材としての窓板２２に侵入警戒装置を取り付けて、窓からの侵入者を警戒するようにしても良い。すなわち、侵入警戒装置は人感センサ１を屋外側、警戒装置本体２を屋内側とし、連結部３の両側片３ｂ，３ｃの間に窓板２２を挟むとともに、窓板２２のスライド方向の端部と窓枠２１との間の隙間に連結部３の中央片３ａを挟んだ状態で窓板２２に取り付けられる。
【００１７】
ここで、人感センサ１は、人体から放射される熱線を検出することによって窓の外側に設定された検知領域１ａにおける人の存否を検出しており、検知領域１ａ内で人体を検出すると人体検出信号を制御回路８に出力する。この時、切替スイッチＳＷにより警戒状態に切り替えられていれば、制御回路８はスピーカＳＰより警報音や生活音（例えば人の声やメロディ音や電話の音など）を鳴らして、侵入者を威嚇したり、住宅内に人がいると錯覚させる。また、制御回路８は照明駆動回路４によりランプＬを点灯させており、ランプＬの光を窓板２２に照射させることによって住宅内の照明が点灯したように見せかけ、住宅内に人がいると錯覚させることができ、またランプＬを瞬間的に点灯させることによってフラッシュがたかれて写真が撮られたように錯覚させることもできる。また同時に、制御回路８は、リレー駆動信号をリレー駆動回路５に出力するとともに、無線送信信号を無線回路７に出力しており、リレー駆動回路５がリレー駆動信号に応じてリレー接点をオン又はオフさせることによって、外部接続端子ｔ１，ｔ２に接続された外部機器に対して接点信号を出力することができ、また無線回路７が無線送信信号に応じて電波信号で警報信号を送信することによって、侵入者の検知状況を遠隔から監視することができる。
【００１８】
なお、侵入警戒装置を窓板２２に取り付けた場合にも、人感センサ１が窓板２２の屋外側、警戒装置本体２が窓板２２の屋内側に配置されるので、屋内から切替スイッチＳＷを操作して、警戒状態と非警戒状態とを切り替えることができる。また、屋外側に設置された人感センサ１が破壊されたとしても、屋内側に設置された警戒装置本体２は無事なので、例えば人感センサ１が接続される制御回路８の入力端子間が開放状態となるのを検出することによって、制御回路８がスピーカＳＰなどから警報を発生させることができる。
【００１９】

[0013]
FIG. 3 shows a block diagram of this intrusion warning device. Inside the warning device main body 2, light L1 is directed toward the speaker SP and a viewing window 20a for visitor confirmation provided in the entrance door 20. In response to a lamp L (light projecting unit) to be irradiated, an illumination drive circuit 4 for lighting the lamp L in response to a lighting control signal input from the control circuit 8 described later, and a relay drive signal input from the control circuit 8 A relay drive circuit 5 that excites a relay coil (not shown), a relay contact 6 that is connected between the external connection terminals t1 and t2 and opens / closes in accordance with excitation / de-excitation of the relay coil, and a control circuit 8 A radio circuit 7 (wireless transmission unit) that transmits an alarm signal using a radio wave signal in response to a radio transmission signal, and a control circuit that includes, for example, a microcomputer and controls the operation of each unit in accordance with a detection signal from the human sensor 1 A switch SW (operation switching unit) which is arranged on one side of the alerting device main body 2 and switches the operation of the control circuit 8 between the alerting state and the non-alarming state; And a stabilized power supply 10 for generating The relay drive circuit 5 and the relay contact 6 constitute a contact signal output unit that outputs a contact signal to the outside.
[0014]
Here, the operation of the intrusion warning device will be briefly described. When the suspicious person A approaches the entrance from the outside as shown in FIG. 4 while being switched to the alert state by the changeover switch SW, the human sensor 1 detects the suspicious person A and sends the human body detection signal to the control circuit. The control circuit 8 serving as an alarm generation unit sounds an alarm sound or a living sound (for example, a human voice, a melody sound, a telephone sound, etc.) from the speaker SP in response to the human body detection signal, and threatens the intruder. Or the illusion that there are people in the house. At the same time, the control circuit 8 turns on the lamp L by the illumination drive circuit 4 and makes it appear as if the entrance illumination is turned on through the viewing window 20a, causing the suspicious person A to have the illusion that there is a person inside. At the same time, the control circuit 8 outputs a relay drive signal to the relay drive circuit 5 and outputs a radio transmission signal to the radio circuit 7, and the relay drive circuit 5 turns on or off the relay contact according to the relay drive signal. By turning off, a contact signal can be output to an external device connected to the external connection terminals t1 and t2, and the radio circuit 7 transmits an alarm signal as a radio signal in response to a radio transmission signal.

For example, the input terminal of the control circuit 8 to which the human sensor 1 is connected is connected. By detecting the open state, the control circuit 8 can generate an alarm from the speaker SP or the like.
[0016]
By the way, in this embodiment, although the case where the intrusion warning device was attached to the entrance door 20 was described as an example, the installation site of the intrusion alert device is not intended to be limited to the entrance door 20 but on the outer wall of the building. Any member other than the front door 20 (for example, a window plate) may be used as long as it is an opening / closing member that can be freely opened and closed in the provided opening. For example, as shown in FIGS. An intrusion warning device may be attached to a window plate 22 as an opening / closing member attached to the frame 21 so as to be freely opened and closed so as to warn an intruder from the window. That is, the intrusion warning device has the human sensor 1 on the outdoor side and the warning device main body 2 on the indoor side, sandwiches the window plate 22 between the both side pieces 3b and 3c of the connecting portion 3, and the end of the window plate 22 in the sliding direction. It attaches to the window board 22 in the state which pinched | interposed the center piece 3a of the connection part 3 in the clearance gap between a part and the window frame 21. FIG.
[0017]
Here, the human sensor 1 detects the presence / absence of a person in the detection area 1a set outside the window by detecting heat rays radiated from the human body. When the human body is detected in the detection area 1a, the human body A detection signal is output to the control circuit 8. At this time, if the changeover switch SW is switched to a warning state, the control circuit 8 sounds an alarm sound or a living sound (for example, a human voice, a melody sound, a telephone sound, etc.) from the speaker SP to threaten the intruder. Or the illusion that there are people in the house. In addition, the control circuit 8 turns on the lamp L by the illumination driving circuit 4, and illuminates the interior of the house by irradiating the light of the lamp L to the window plate 22, and there is a person in the house. An illusion can be made, and by illuminating the lamp L momentarily, the illusion can be made as if a flash was taken and a photograph was taken. At the same time, the control circuit 8 outputs a relay drive signal to the relay drive circuit 5 and outputs a radio transmission signal to the radio circuit 7, and the relay drive circuit 5 turns on or off the relay contact according to the relay drive signal. By turning off, a contact signal can be output to an external device connected to the external connection terminals t1 and t2, and the radio circuit 7 transmits an alarm signal as a radio signal in response to a radio transmission signal. Intruder detection status can be monitored remotely.
[0018]
Even when the intrusion warning device is attached to the window plate 22, the human sensor 1 is arranged on the outdoor side of the window plate 22 and the warning device main body 2 is arranged on the indoor side of the window plate 22. Can be switched between a warning state and a non-warning state. Even if the human sensor 1 installed on the outdoor side is destroyed, the alarm device main body 2 installed on the indoor side is safe. For example, the input terminal of the control circuit 8 to which the human sensor 1 is connected is connected. By detecting the open state, the control circuit 8 can generate an alarm from the speaker SP or the like.
