【００１０】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
【００１１】
（実施形態１）
図１、図２（ａ），（ｂ），（ｃ）、及び図３に、屋内から屋外に向けて開く外開きの玄関扉に対応した本実施形態の防犯機器の取り付け状態図を示す。玄関扉２０（開閉部材）は、閉時に屋内側Ｙを建物の扉枠２３の上端に設けた戸当たり部２４に当接させることによって、屋外側Ｘ方向のみに開く外開き構造となっている。
【００１２】
防犯機器は、玄関扉２０の屋外側Ｘに取り付けられ、人体から放射される熱線を検知することにより玄関扉２０の屋外側Ｘに設けた検知エリア１ａにおける人の存否を検知する、例えば焦電素子からなるセンサ部１ｂを備えた検知ユニット１と、玄関扉２０の屋内側Ｙに取り付けられ、正面側から背面側になるにつれて下方向に傾斜した傾斜面Ｍを有する底面を備え、警報発生動作を設定する操作部たる切替スイッチＳＷ１，ＳＷ２を傾斜面Ｍに設けた警戒装置本体２と、検知ユニット１と警戒装置本体２との間を連結する、例えば金属部材等から形成された連結部３とで構成される。
【００１３】
連結部３は中央片３ａと、中央片３ａから略垂直に折曲した側片３ｃとでＬ字状に形成されており、中央片３ａを玄関扉２０の上端部に載置し、側片３ｃを玄関扉２０の屋内側Ｙに当接するようにして玄関扉２０に取り付けられる。そして、中央片３ａの先端部には検知ユニット１を取り付け、側片３ｃの先端部には警戒装置本体２を取り付けることで、検知ユニット１を屋外側Ｘ、警戒装置本体２を屋内側Ｙに配している。このとき、警戒装置本体２が戸当たり部２４より下側に位置するように側片３ｃの長さは設定されているので、玄関扉２０を閉じたときに警戒装置本体２が戸当たり部２４と接触せず、外開きの玄関扉２０に対応した防犯機器を構成することができる。
【００１４】
次に、図４〜図１８に防犯機器の詳細構成の一例を示す。図４〜図９は防犯機器の右側面図、正面図、左側面図、上面図、底面図、背面図を各々示し、図１０（ａ）〜（ｅ）は検知ユニット１のみを連結部３に取り付けた状態での外観図を各々示し、図１１は図１０（ｂ）のＡ−Ａ’断面図を示し、図１２は図１０（ａ）のＢ−Ｂ’断面を示しており、検知ユニット１はボルト４によって連結部３に螺設されている。連結部３は、中央片３ａの先端部に長辺方向に並行して長孔３ｄを形成している。検知ユニット１は、正面側に開口を有するＵ字状の切り欠き１ｃを上面１ｄに形成し、内部には、上面１ｄに並行で且つボルト４を挿通する挿通孔１ｆを備えた面１ｅを設けている。そして、前面側から連結部３の中央片３ａを上面１ｄと面１ｅとの間の空間に遊嵌させ、ボルト４を長孔３ｄ、挿通孔１ｆを介して、面１ｅの底面側に設けたナット１ｇに螺嵌させることによって、検知ユニット１を連結部３に取り付けている。
【００１５】
次に、図１３〜図１７に示す警戒装置本体２の正面図、左側面図、上面図、底面図、背面図、図１８に示す右側面断面図を用いて、警戒装置本体２について説明する。警戒装置本体２は、正面側から背面側になるにつれて下方向に傾斜した傾斜面Ｍを有する底面を備え、上下方向を長辺方向とする略函形形状であり、傾斜面Ｍには、スピーカＳＰが発する音を切・小・大のうちいずれかに切り替えるスライド式の切替スイッチＳＷ１と、スピーカＳＰが発する音をピンポン（ピンポン音）・犬の鳴き声（ワンワン）・アラーム音（アラーム）のうちいずれかに切り替えるスライド式の切替スイッチＳＷ２とを備えている。正面上部には動作電源となる電池の収納部を覆う電池蓋２０を備え、正面中央部にはスピーカＳＰを備え、背面には、連結部３の側片３ｃに取り付けるための取付け部Ｈを備えている。
【００１６】
この防犯機器を、図１に示すように中央片３ａを玄関扉２０の上端部に載置し、側片３ｃを玄関扉２０の屋内側Ｙに当接するようにして玄関扉２０に取り付けた場合、警戒装置本体２は上下方向に長い函形形状を有しているので、操作部の位置を低くすることができ、背の低い人であっても切替スイッチＳＷ１，ＳＷ２の操作を容易に行うことができる。
【００１７】
次に、この防犯機器の動作を図１９の回路ブロック及び図２０の動作フローを用いて説明する。警戒装置本体２は、マイコン２ａと音響回路２ｂとスピーカＳＰとを備えてセンサ部１ｂが人を検知すると警報を発生する警報発生部を備えている。この防犯機器は、切替スイッチＳＷ１によりスピーカ音量が大または小に切り替えられている警戒状態において、侵入者が外部から玄関扉２０に近付いて検知エリア１ａに入り込むと（ステップＳ１）、検知ユニット１のセンサ部１ｂが侵入者を検知して人体検知信号を警戒装置本体２の動作を制御するマイコン２ａに出力する（ステップＳ２）。それを受けたマイコン２ａは、音響回路２ｂを介してスピーカＳＰより、ピンポン音、犬の鳴き声、アラーム音のうち切替スイッチＳＷ２によって選択されたいずれかの音を、切替スイッチＳＷ１で設定した音量で出力して、例えば犬の鳴き声であれば室内に犬がいると侵入者Ａに錯覚させ、ピンポン音またはアラーム音であれば侵入者に警告を発することで（ステップＳ３）、侵入者の侵入を防ぐことができる。なお、警戒状態を解除する場合には、切替スイッチＳＷ１を切に切り替えておけばよい。
【００１８】
さらに、万が一屋外に設置されたセンサ部１ｂが壊されたとしても、屋内に設置された警戒装置本体２は無事なので、警戒装置本体２より警報を発生させることができる。
【００１９】
また、図２１に示すように、閉時に玄関扉２０の屋外側Ｘを戸当たり部２４に当接させることによって、屋内側Ｙ方向のみに開く内開き構造の場合、検知ユニット１を戸当たり部２４より下側に位置させることで、玄関扉２０を閉じたときに検知ユニット１が戸当たり部２４と接触しない、内開きの玄関扉２０に対応した防犯機器（図２２にその側面図を示す）を構成することができる。この場合の連結部３は中央片３ａと、中央片３ａの両端から略垂直に折曲した側片３ｂ，３ｃ（側片３ｃは図３と同様）と、側片３ｂから垂直に折曲した側片（図示無し）とで形成され、側片３ｂから垂直に折曲した側片の先端部には検知ユニット１を取り付け、側片３ｃには警戒装置本体２を取り付けており、検知ユニット１が戸当たり部２４より下側に位置するように側片３ｂの長さは設定されている。
【００２０】
（実施形態２）
本実施形態では、屋内から屋外に向けて開く外開きと、屋外から屋内に向けて開く内開きとのいずれの構造の玄関扉２０にも対応した防犯機器について説明する。なお、玄関扉２０、扉枠２３の構成については図３または図２１と同様とし、実施形態１と同様に、防犯機器は、玄関扉２０の屋外側Ｘに取り付けられ、人体から放射される熱線を検知することにより玄関扉２０の屋外側Ｘに設けた検知エリア１ａ（図２参照）における人の存否を検知する、例えば焦電素子からなるセンサ部１ｂを備えた検知ユニット１と、玄関扉２０の屋内側Ｙに取り付けられ、正面側から背面側になるにつれて下方向に傾斜した傾斜面Ｍを有する底面を備え、警報発生動作を設定する操作部たる切替スイッチＳＷ１，ＳＷ２を傾斜面Ｍに設けた警戒装置本体２と、検知ユニット１と警戒装置本体２との間を連結する、例えば金属部材等から形成された連結部３とで構成される。
【００２１】
図２３〜図２８は、防犯機器の右側面図、正面図、左側面図、上面図、底面図、背面図を各々示し、連結部３は中央片３ａと、中央片３ａの両端から略垂直に折曲した側片３ｂ，３ｃと、側片３ｂから垂直に折曲した側片３ｅとで形成されており、側片３ｅの先端部には検知ユニット１を取り付け、側片３ｃの先端部には警戒装置本体２を取り付けている。
【００２２】
また、図２４のＣ−Ｃ’断面図である図２９、及び図２６のＤ−Ｄ’断面図である図３０に示すように、検知ユニット１と側片３ｅとの取り付けは実施形態１と同様であるので説明は省略する。
【００２３】
この防犯機器を、中央片３ａを玄関扉２０の上端部に載置して玄関扉２０に取り付けた際に、側片３ｅの先端部に取付けられた検知ユニット１、及び側片３ｃの先端部に取付けられた警戒装置本体２が戸当たり部２４より下側に位置するように側片３ｂ，３ｃの長さは設定されているので、玄関扉２０を閉じたときに検知ユニット１及び警戒装置本体２が戸当たり部２４と接触せず、外開きと内開きとのいずれの構造の玄関扉２０にも対応した防犯機器を構成することができる。
【００２４】
また、警戒装置本体２は実施形態１と同様に上下方向に長い函形形状を有しているので、操作部の位置を低くすることができ、背の低い人であっても切替スイッチＳＷ１，ＳＷ２の操作を容易に行うことができる。
【００２５】
なお、本実施形態の防犯機器の動作は実施形態１と同様であるので説明は省略する。
【００２６】
実施形態１，２においては、防犯機器を玄関扉２０の上端に取り付ける例を示したが、扉枠２３の側端に戸当たり部２４を設けている場合には防犯機器を玄関扉２０の側端に取り付ければ、外開きと内開きとのいずれの構造を有する玄関扉２０にも同様に対応することができる。
