【発明の属する技術分野】
本発明は、ドア枠又は子扉又は扉又は門扉よりなる取付け部材に電気錠のコントローラユニットを取付けるための電気錠のコントローラユニットの取付け構造に関するものである。
【０００２】
【従来の技術】
従来から玄関扉に電気錠が使用されており、この電気錠のコントローラユニットは従来は建物の壁に取付けてある。（例えば特許文献１参照）
このように建物の壁にコントローラユニットが設けてあると、コントローラユニットの位置が扉から離れており、電気錠の開閉操作を使用者がし難いという問題がある。
【０００３】
そこで、扉の吊元側の端面に設けた切欠部内に制御部や受信機を収納し、カードキーによる電気錠の開閉操作を容易にしようとするものが提案されている。（例えば特許文献２参照）
また、扉の外面に突出する把手に設けた凹部にアンテナを備えたリーダ装置を収納してカバーで覆うようにしたものも知られている。（例えば特許文献３参照）

【発明が解決しようとする課題】
電気錠の開閉操作を容易にするために扉の吊元側の端面に設けた切欠部内に制御部や受信機を収納するようにした上記特許文献２においては、受信機のアンテナが扉内に収納されているため、金属製の扉やドア枠等の影響によるカードキー検知距離の劣化があって好ましくないものである。
【０００６】
一方、扉の外面に突出する把手に設けた凹部にアンテナを備えたリーダ装置を収納してカバーで覆う従来例である上記特許文献３においては、金属製の扉やドア枠等の影響によるカードキー検知距離の劣化を無くすことができるが、把手にアンテナ、リーダ装置を設けるため、把手が必要以上に大きくなり、また、リーダ装置を収納するために把手の形状等にも制約がある。しかも、この引用文献３においては、屋外側からは把手に内装したアンテナを利用してカードキーにより電気錠の開閉ができるが、屋内側からの電気錠を開閉するためには屋内側にも上記とは別に屋内側操作ユニットを設ける必要があり、屋外側、屋内側にそれぞれ別々に操作ユニットを設ける必要があり、工事も面倒となるという問題がある。
【０００７】
そこで、本発明の発明者は本発明に至る過程で、図２７に示すようなものを考えた。すなわち、ドア枠又は子扉又は扉又は門扉よりなる取付け部材１に屋内側から屋外側に貫通するように取付け孔２を形成し、電気錠３の開閉を開閉制御するための制御部と屋外側において非接触型のカードキーの情報を読み取って制御部により施解錠するためのアンテナ１６とを備えたコントローラユニット７を上記取付け孔２にはめ込み、コントローラユニット７の屋外側の端部を取付け孔２から屋外側に突出させ、コントローラユニット７の屋内側の端部に設けた巾広部１２を取付け部材１に固着具により固着させることを考えた。そして、上記コントローラユニット７の屋外側に突出した部分の内部にアンテナ１６を配置し、このようにアンテナ１６が屋外側に突出して位置することで、金属製の取付け部材１の影響を受けないようにすることを考えた。この場合、取付け孔２にコントローラユニット７を貫挿して取付けるものにおいて、コントローラユニット７の取付け部分の気密性、断熱性等を確保するため、巾広部１２と取付け部材１の屋内側の面との間に気密材３１を介在させた状態で固着具により巾広部１２を取付け部材１に取付ける必要がある。
【０００８】
ところで、アンテナ１６を内装したコントローラユニット７の屋外側への突出部分の突出長さはできるだけ短い方が外観がよいが、突出長さが短すぎると金属製の取付け部材１の影響を受けて検知距離の劣化が生じる。このため、図２７（ｂ）における寸法Ａで示す突出長さは非常に重大であるが、上記のように、気密性、断熱性等を確保するため、巾広部１２と取付け部材１の屋内側の面との間に弾性を有する気密材３１を介在させた状態で固着具により巾広部１２を取付け部材１に取付けると、上記先端部にアンテナ１６を内装したコントローラユニット７の取付け部材１の外面からの突出長さが変動し、目的とする突出寸法にできない場合が生じることが判明した。
【０００９】
また、図２７のようなものにおいては、屋外側に突出したコントローラユニット７の突出面の一部に孔を開けたりしてコントローラユニット７内の配線や制御回路の電気的操作（短絡等）を行うことで、電気錠３コントローラの誤動作を誘発して解錠する可能性が懸念される。
【００１０】
更に、図２７のようなものにおいては、取付け部材１に設けた取付け孔２の屋外側の開口縁が露出して外観が良くないという問題がある。
【００１１】
また、従来においては玄関のドア枠又は子扉又は扉に取付けるアンテナを備えたコントローラユニットと、門扉に取付けるアンテナを備えたコントローラユニットとは異なる種類のものであり、玄関のドア枠又は子扉又は扉に取付けものと、門扉に取付けるものとを共通のアンテナを備えたコントローラユニットにより兼用させるようなものはなかった。
【００１２】
本発明は上記の点に鑑みてなされたものであり、簡単な構成で、アンテナの取付け部材の屋外側面からの突出長さを一定にでき、しかも、屋外側においてコントローラユニットの一部を部分的に破壊されても、コントローラユニット内の配線や制御回路の電気的操作（短絡等）が出来にくくして防犯効果を高めることができ、また、取付け部材に設けた取付け孔の屋外側の開口縁が露出しないようにできて外観を向上でき、また、防水性を向上できると共に取付け部材の厚みが異なる場合にも対応できて、玄関のドア枠又は子扉又は扉に取付けるアンテナを備えたコントローラユニットと、門扉に取付けるアンテナを備えたコントローラユニットとを共通のもので兼用できる電気錠のコントローラユニットの取付け構造を提供することを課題とするものである。
【００１３】
【課題を解決するための手段】
上記課題を解決するために本発明に係る電気錠のコントローラユニットの取付け構造は、ドア枠又は子扉又は扉又は門扉よりなる取付け部材１に屋内側から屋外側に貫通するように取付け孔２を形成し、電気錠３の開閉を開閉制御するための制御部４と屋外側において非接触型のカードキー５の情報を読み取って制御部４により施解錠するためのアンテナ１６とを備えたコントローラユニット７を上記取付け孔２にはめ込んで取付ける電気錠３のコントローラユニット７の取付け構造であって、取付け孔２の屋外側開口部８の大きさを取付け孔２の他の部分よりも小さな開口とし、コントローラユニット７の本体部９の外形の大きさを取付け孔２の屋外側開口部８よりも大きく且つ取付け孔２の屋内側開口部１１よりも小さい大きさとし、この本体部９の屋外側面に外形の大きさが取付け孔２の屋外側開口部８よりも小さい屋外側突出部１０を突設し、本体部９の屋内側端部に外形の大きさが取付け孔２の屋内側開口部１１よりも大きい巾広部１２を形成し、屋外側突出部１０内にアンテナ１６を配設し、本体部９を取付け孔２に屋内側から嵌め込み且つ屋外側突出部１０を取付け孔２の屋外側開口部８から屋外側に突出させ且つ巾広部１２を取付け部材１の屋内側面に対向させて位置させ、本体部９と屋外側突出部１０の間の段部３２を取付け孔２の屋外側開口部８の縁部の屋内側面に当接すると共に巾広部１２と取付け孔２の屋内側開口部１１の縁部外周の取付け部材１の屋内側端部との間に気密材３１を介在させた状態で巾広部１２を取付け部材１に固着具４２により固着して成ることを特徴とするものである。
【００１４】
このような構成とすることで、気密材３１を介して巾広部１２を固着具４２により取付け部材１に固着する際、コントローラユニット７の本体部９と屋外側突出部１０の間の段部３２が取付け孔２の屋外側開口部８の縁部の屋内側面に当接するまで締め付けることで、屋外側突出部１０の突出長さを一定にでき、最も突出長さが短く且つ金属製の取付け部材１に影響されることなくアンテナ部６の検知距離の劣化が認められない設計上の突出距離を確保できるものである。
【００１５】
また、ドア枠又は子扉又は扉又は門扉よりなる取付け部材１に屋内側から屋外側に貫通するように取付け孔２を形成し、電気錠３の開閉を開閉制御するための制御部４と屋外側において非接触型のカードキー５の情報を読み取って制御部４により施解錠するためのアンテナ１６とを備えたコントローラユニット７を上記取付け孔２にはめ込んで取付ける電気錠３のコントローラユニット７の取付け構造であって、取付け孔２の屋外側開口部８及び屋内側開口部１１の大きさを同じ大きさとし、取付け孔２の屋外側開口部８に該開口部よりも小さい開口部を有するアタッチメント部材５０を取付けると共に屋内側開口部１１に対応するアタッチメント部材５０の屋内側の部位に位置決め用当たり部５５を設け、コントローラユニット７の本体部９の外形の大きさをアタッチメント部材５０の開口部５１よりも大きく且つ取付け孔２の屋内側開口部１１より小さい大きさとし、この本体部９の屋外側面に外形の大きさがアタッチメント部材５０の開口部５１よりも小さい屋外側突出部１０を突設し、本体部９の屋内側端部に外形の大きさが取付け孔２の屋内側開口部１１よりも大きい巾広部１２を形成し、屋外側突出部１０内にアンテナ１６を配設し、本体部９を取付け孔２に屋内側から嵌め込み且つ屋外側突出部１０をアタッチメント部材５０の開口部５１から屋外側に突出させ且つ巾広部１２を取付け部材１の屋内側面に対向させて位置させ、本体部９と屋外側突出部１０の間の段部３２をアタッチメント５０の屋内側面の位置決め用当たり部５５に当接すると共に巾広部１２と取付け孔２の屋内側開口部１１の縁部外周の取付け部材１の屋内側端部との間に気密材を介在させた状態で巾広部１２を取付け部材１に固着具により固着して成ることを特徴とするものであってもよい。
【００１６】
このような構成とすることで、気密材３１を介して巾広部１２を固着具４２により取付け部材１に固着する際、コントローラユニット７の本体部９と屋外側突出部１０の間の段部３２が取付け孔２の屋外側開口部８に設けたアタッチメント部材５の開口部５１の縁部の屋内側面に当接するまで締め付けることで、屋外側突出部１０の突出長さを一定にでき、最も突出長さが短く且つ金属製の取付け部材１に影響されることなくアンテナ部６の検知距離の劣化が認められない設計上の突出距離を確保できるものである。しかも、取付け孔２の屋外側開口部８及び屋内側開口部１１の大きさを同じ大きさとし、取付け孔２の屋外側開口部８に該開口部よりも小さい開口部５１を有するアタッチメント部材５０を取付けると共に屋内側開口部１１に対応するアタッチメント部材５０の屋内側の部位に位置決め用当たり部５５を設けるので、取付け部材１の両側面のうちどちらの面が屋外側の面となるように施工されたとしても、取付け孔２における屋外側の面となる方の屋外側開口部８にアタッチメント部材５０を取付けることで対応して上記のように、屋外側突出部１０の突出長さを一定にでき、最も突出長さが短く且つ金属製の取付け部材１に影響されることなくアンテナ部６の検知距離の劣化が認められない設計上の突出距離を確保できるものである。
【００１７】
また、屋外側突出部１０及び屋外側突出部１０の周囲部分を覆う屋外側化粧プレート１３を設けることが好ましい。
【００１８】
このような構成とすることで、屋外側突出部１０のカバーができるだけでなく、屋外側突出部１０の突出部分の周囲をカバーできて外観が良くなるものである。
【００１９】
また、アルミニウム板１４の屋外側面にフェライト板１５を積層し、該フェライト板１５の屋外側面にアンテナ１６を積層してアンテナ部６を構成することが好ましい。
【００２０】
このような構成とすることで、フェライト板１５で磁気シールドできてアンテナ１６による受信性能をよくすることが出来、また、背面にアルミニウム板１４が存在するため、仮にコントローラユニット７の屋外側突出部１０の突出部分の一部に不正な侵入者が孔をあけるなどして一部分が破壊されても、アルミニウム板１４によりコントローラユニット７内の配線や制御回路の電気的操作（短絡等）が出来にくくして防犯効果を高めることができるものである。
【００２１】
また、コントローラユニット７のハウジング１７を、屋外側突出部１０、本体部９を備え且つ内部が中空部で屋内側に開口したケース１８と、該ケース１８の屋内側の開口１９に取付けられた巾広部１２を構成するカバー２０とで構成し、押さえ金具２１の屋外側端部に押さえ片２２を設ける共に屋内側端部に係止片２３を設け、ケース１８の屋外側突出部１０の内部にアンテナ部６を入れ、ケース１８内に入れた押さえ金具２１の押さえ片２２により弾性を有する介在物２４を介してアンテナ部６の屋内側面を押圧し、押さえ金具２１の係止片２３をケース１８の屋内側の開口１９の縁部に設けた切り欠き２５に係止し、ケース１８の屋内側端部に取付けたカバー２０により押さえ金具２１を押圧することが好ましい。
【００２２】
このような構成とすることで、ケース１８内にアンテナ部６を入れ、弾性を有する介在物２４を介して押さえ金具２１で押さえ、押さえ金具２１をケース１８に取付けるカバー２０で押圧することで、アンテナ部６の組み込みが簡単に行えるものであり、この場合、押さえ金具２１の係止片２３をケース１８の屋内側の開口１９の縁部に設けた切り欠き２５に係止するので、押さえ金具２１がずれることなく正確にアンテナ部６の保持ができるものである。
【００２３】
また、押さえ金具２１に電源線や電気錠３への信号線等のコードを巻き付けるためのコード巻き付け部２６を設け、ケース１８の側面にコントローラユニット７のコード２７を外部に引き出すための引き出し用開口部２８を形成し、押さえ金具２１にコード２７の引き出し用開口部２８側に向けて突出する突片２９を設け、該突片２９をはめ込んで支持するためのコード２７の引き出し方向と反対側に開口した支持凹部３０をケース１８に設けることが好ましい。
【００２４】
このような構成とすることで、アンテナ部６を押圧して保持するための押さえ金具２１をコード２７の張力止め部材として兼用できるものであり、特に、引き出し用開口部２８から引き出したコード２７に張力がかかった場合、突片２９が支持凹部３０にはめ込んで支持してあるので、押さえ金具２１が引き出し用開口部２８側にずれるのを防止できて、確実にコード２７の張力止めができるものである。
【００２５】
また、巾広部１２と取付け孔２の屋内側開口部１１の縁部外周の取付け部材１の屋内側端部との間にスペーサ部材５２を介在させた状態で巾広部１２を取付け部材１に固着具４２により固着することが好ましい。
【００２６】
このような構成とすることで、取付け部材１の厚みが異なるものにおいても、スペーサ部材５２を介在することで、取付け部材１に本体部９を同じ条件で取付けることができるものである。
【００２７】
また、巾広部１２とスペーサ部材５２との間に気密材３１を介在させると共に、該気密材３１と同形状の気密材５３をスペーサ部材５２と取付け部材１との間に介在させることが好ましい。
【００２８】
このような構成とすることで、スペーサ部材５２を設けたとしても、スペーサ部材５２と巾広部１２との間、スペーサ部材５２と取付け部材１との間からの水の浸入を上記気密材３１、５３により防止できて、取付け部材１が門扉の場合であっても内部に雨水が浸入しないようにできるものである。また、気密材３１と気密材５３とを同形状とすることで、同じ形状の気密材を兼用できるものである。
【００２９】
また、本体部９とアタッチメント部材５０との間に気密材５４を介在させることが好ましい。
【００３０】
このような構成とすることで、アタッチメント部材５０を取付けたとしてもアタッチメント部材５０の取付け部分から水が浸入するのを防止できて、取付け部材１が門扉の場合であっても内部に雨水が浸入しないようにできるものである。
【００３１】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００３２】
まず、アンテナ１６とを備えたコントローラユニット７を取付ける取付け部材１がドア枠又は子扉又は扉の場合の例につき説明する。
【００３３】
図１２に示すような玄関ドア装置のような出入り口ドア装置Ａは、開閉自在な扉３３を有するドアユニットと、扉３３の施解錠を電気的に行う電気錠３とを備えており、更に、この出入り口ドア装置Ａには電気錠３の施解錠の制御を行うための制御部４を収納した図６、図７に示すようなコントローラユニット７を設けてある。また、コントローラユニット７には非接触型のカードキー５の情報を読み取って制御部４により施解錠するためのアンテナ部６が内装してあり、また、屋内側から電気錠の開閉操作をしたり、カードキー５への暗証番号の登録を行ったりするための屋内側操作部３４が設けてある。
【００３４】
ドアユニットは例えば、図１２に示すようにドア枠３６と扉３３、又はドア枠３６と扉３３と袖壁とで構成してあり、扉３３としては単体の場合、又は図示を省略しているが主扉と子扉とで構成した場合とがある。電気錠３はデッドボルトと、デッドボルトを駆動するデッドボルト駆動部と、デッドボルトが突出した際に挿入自在となったデッドボルト受け部とで構成してあり、デッドボルト駆動部は制御部４からの制御信号により駆動してデッドボルトを出没自在としている。
【００３５】
コントローラユニット７は出入り口ドア装置Ａのドア枠３６又は子扉又は扉３３よりなる取付け部材１に取付けられる（実施形態ではドア枠３６に取付けてある）。取付け部材１を構成するドア枠３６は金属製（例えばアルミニウム製）の中空筒状をしており、屋内側から屋外側に貫通するように取付け孔２が形成してあり、この取付け孔２は屋外側開口部８が屋内側開口部よりも小さく設定してあり、添付図面に示す実施形態では図１のように中空筒状のドア取付け部材１の屋内側面部と屋外側面部とにそれぞれ屋内側開口部１１、屋外側開口部８を設けて屋内外に貫通する取付け孔２が形成してあって、中空筒状のドア取付け部材１の屋内側開口部１１、屋外側開口部８間の部分は中空となっている。この取付け孔２にコントローラユニット７を貫挿して取付けてある。
【００３６】
コントローラユニット７の外殻を構成するハウジング１７は図６に示すように本体部９と、本体部９の屋外側端部に突設した屋外側突出部１０と、本体部９の屋内側端部に設けた巾広部１２とで構成してあり、上記本体部９の外形の大きさは取付け孔２の屋外側開口部８よりも大きく且つ取付け孔２の屋内側開口部１１よりも小さい大きさとなっており、この本体部９の屋外側面に外形の大きさが取付け孔２の屋外側開口部８よりも小さい屋外側突出部１０を突設してあり、本体部９の屋内側端部に外形の大きさが取付け孔２の屋内側開口部１１よりも大きい巾広部１２を形成してある。
【００３７】
上記コントローラユニット７のハウジング１７は、図６、図７に示すように、屋外側突出部１０、本体部９を備え且つ内部が中空部で屋内側に開口した箱状のケース１８と、該ケース１８の屋内側の開口１９に取付けられた巾広部１２を構成するカバー２０とで構成してある。
【００３８】
図８に示すような箱状のケース１８の屋外側突出部１０内にはアンテナ部６が内装してある。アンテナ部６は図１１に示すようなもので、アルミニウム板１４の屋外側面にフェライト板１５を積層し、該フェライト板１５の屋外側面にアンテナ１６を積層してアンテナ部６を構成してある。
【００３９】
図中２１は押さえ金具であって、屋内外方向に伸びた中央片２２ａの屋外側端部に中央片２２ａに対して直角に押さえ片２２を突設し、中央片２２ａの屋内側端部に押さえ片２２の中央片２２ａと直角で且つ突出方向と逆方向に係止片２３を突設し、更に、中央片２２ａからＬ字状をした突片２９を突設して押さえ金具２１が構成してある。
【００４０】
また、図６に示すように、箱状のケース１８の一側部にはコントローラユニット７のコード２７を外部に引き出すための引き出し用開口部２８が設けてあり、また、ケース１８の内部にはコード２７の引き出し方向と反対側（つまり引き出し用開口部２８と反対側）に開口した支持凹部３０が設けてあり、ケース１８の屋内側の開口１９の縁部に切り欠き２５が設けてある。また、ケース１８の屋内側の開口１９の縁部の四隅部を外側に突出させて、この部分に挿入孔３７が設けてある。
【００４１】
そして、箱状のケース１８の屋外側突出部１０内（つまり箱状のケース１８の内部の先端部の突出して凹んだ部分）にケースの屋内側の開口１９からアンテナ部６をアルミニウム板１４が屋内側、アンテナ１６が屋外側という位置関係となるように差し込み、次に、押さえ金具２１を開口１９からケース１８内に入れて、押さえ金具２１の押さえ片２２により弾性を有する介在物２４を介してアンテナ部６の屋内側面を押圧し、押さえ金具２１の係止片２３をケース１８の屋内側開口部１９の縁部に設けた切り欠き２５に係止し、ケース１８の屋内側端部に取付けたカバー２０をケース１８の開口１９に被せて押さえ金具２１を押圧し、この状態で、ケース１８の開口１９の縁部の四隅部に設けた挿入孔３７からねじ具３８を挿入してカバー２０を固着してある（ねじ具３８はカバー２０に設けたねじ固定用孔部３８ａに固着してある）。これにより、アンテナ部６を押さえ金具２１を介してケース１８にカバー２０をねじ具３８で取付けることで簡単に屋外側突出部１０内の所定位置に内装できるものである。
【００４２】
カバー２０は図９に示すようなもので、カバー２０には屋内側から電気錠の開閉操作をしたり、カードキー５への暗証番号の登録を行ったりするための屋内側操作部３４が設けてあり、また、このカバー２０の上部と下部とには屋内側面に上下にスライド蓋２０ａが設けてあり、スライド蓋２０ａをスライドして開くと、カバー２０の上部と下部とにねじ挿入孔４０が露出するようになっている。カバー２０内には図９のように制御部４が内装してある。
【００４３】
押さえ金具２１の屋内外方向に伸びた中央片２２ａはケース１８から離れて位置させてあり、この中央片２２ａを電源線や電気錠３への信号線等のコード２７を巻き付けるためのコード巻き付け部２６としてある。そして、図８（ｃ）のように中央片２２ａに巻き付けたコントローラユニット７のコード２７は引き出し用開口部２８から外部に引き出されるものである。この場合、中央片２２ａに設けた突片２９が支持凹部３０にはめ込んであることで、コード２７に引き出し方向に張力が作用しても押さえ金具２１が引き出し用開口部２８側にずれるのを防止できて、確実にコード２７の張力止めができるようになっている。
【００４４】
上記のような構成のコントローラユニット７を取付け部材１に取付けるには以下のようにして行うものである。すなわち、コントローラユニット７の本体部９を取付け部材１の取付け孔２に屋内側から嵌め込み、屋外側突出部１０が取付け孔２の屋外側開口部８から屋外側に突出させる。この場合、巾広部１２が取付け部材１の屋内側面に対向するのであるが、この巾広部１２と取付け孔２の屋内側開口部１１の縁部外周の取付け部材１の屋内側端部との間に弾性を有する表面に薄金属板を積層した合成樹脂発泡体のような弾性を有する気密材３１を介在させた状態で、カバー２０のねじ挿入孔４０から固着具４２であるねじ具を挿入してねじ具を取付け部材１の屋内側面部に固着する。この時、本体部９と屋外側突出部１０の間の段部３２を取付け孔２の屋外側開口部８の縁部の屋内側面に当接するまでねじ具を締め付けることで取付けが完了する。このように、本体部９と屋外側突出部１０の間の段部３２を取付け孔２の屋外側開口部８の縁部の屋内側面に当接していることで、取付け部材１の屋外側面からの屋外側突出部１０の突出長さが一定にでき（つまり屋外側突出部１０内に内装したアンテナ１６の取付け部材１からの突出長さが一定にでき）、検知距離の劣化が認められない最も少ない突出長さにすることができるものである。気密材３１は上記のように固着具４２を構成するねじ具を締め付けることで圧縮されてコントローラユニット７の取付け部分の気密性、断熱性、水密性を確保するものである。また、カバー２０の上部と下部はスライド蓋２０ａを閉じることで固着具４２が屋内側に露出しないようになっている。
【００４５】
取付け部材１の取付け孔２から屋外側に突出した屋外側突出部１０には図４に示すように屋外側化粧プレート１３を取付けて取付け孔２の屋外側開口部８を屋外側化粧プレート１３で覆うようになっている。屋外側化粧プレート１３の取付けに当たっては、例えば、図１０に示すように、屋外側化粧プレート１３から係止爪４３を突設し、この係止爪４３を屋外側突出部１０の側面部に設けた係止凹部４４に係止することにより取付けるようにするものである。これにより屋外側化粧プレート１３を取付けない場合には図５のように開口部８の開口縁が見えるが、図４に示すように屋外側化粧プレート１３を取付けることで、開口部８の開口縁が隠されて外観が良くなるものである。
【００４６】
ところで、アンテナ部６は背面にアルミニウム板１４が存在するため、仮にコントローラユニット７の屋外側突出部１０の突出部分の一部に不正な侵入者が孔をあけるなどして一部分が破壊されても、アルミニウム板１４全体を屋外側に取り出すことができず、したがって、アルミニウム板１４によりコントローラユニット７内が突出部１０と、突出部１０よりも屋内側の部分とに仕切られることになり、コントローラユニット７内の配線や制御回路が露出せず、浸入犯が屋外側からコントローラユニット７内の配線や制御回路の電気的操作（短絡等）が出来にくくして防犯効果を高めることができるものである。
【００４７】
図１３には電気錠３の制御システムの概略制御ブロック図が示してある。暗証コードが書き込まれたカードキー５を屋外においてコントローラユニット７の屋外側突出部１０に近づけることで、カードキー５に書き込まれた暗証コードをアンテナ１６、送受信部４５を介して認証／書換部４６で記憶部４７に記憶されている正規に登録された暗証コードであるか否かの認証を行い、正規の暗証コードと認証されると制御部４により電気錠３の施解錠を行うようになっている。
【００４８】
また、屋内側において、屋内側操作部３４を操作すると制御部４により電気錠３の施解錠を行うようになっている。
【００４９】
コントローラユニット７には施錠や解錠を報知したりするためのＬＥＤやブザー等の報知部４８が設けてある。
【００５０】
なお、屋内側操作部３４においてカードキー５の暗証コードの書き換え操作ができるようになっており、この場合、認証／書換部４６で書換えられた新たな暗証コードが記憶部４７に登録されるようになっている。
【００５１】
ところで、上記実施形態においては、アンテナ１６とを備えたコントローラユニット７を取付ける取付け部材１がドア枠又は子扉又は扉の場合の例につき説明したが、アンテナ１６とを備えたコントローラユニット７を取付ける取付け部材１としては門扉であってもよいものである。つまり、本発明においては、共通のコントローラユニット７をドア枠又は子扉又は扉に取付けたり、あるいは、門扉に取付けることができるようにしている。
【００５２】
門扉の場合、取付け部材１を構成する金属製の門扉の框１ａは中空筒状をしており、屋内側（敷地内側）から屋外側（道路側）に貫通するように取付け孔２が形成してある。ここで、取付け孔２が前述の実施形態と同様に屋外側開口部８が屋内側開口部１１よりも小さく設定してある場合には、前述の実施形態と同様に、この取付け孔２にコントローラユニット７を貫挿して取付けるものである。取付け構造は前述の実施形態と同様であるので省略する。そして、取付け部材１が門扉の場合も、前述の実施形態と同様の作用、効果を有している。この点については説明が重複するので省略する。
【００５３】
次に、本発明の他の実施形態を図１４乃至図２１に基づいて説明する。前述の各実施形態においては、いずれも、取付け部材１に屋内側から屋外側に貫通するように設けた取付け孔２の屋外側開口部８が屋内側開口部１１よりも小さく設定した例につき説明したが、本実施形態においては、図１４、図１６に示すように取付け孔２の屋外側開口部８と屋内側開口部１１とが同じ大きさとなっている。このように取付け孔２の屋外側開口部８と屋内側開口部１１とが同じ大きさとなったものにおいては、図１４乃至図１７に示すように、取付け部材１の屋外側面に屋外側開口部８の周囲を囲むように枠状をしたアタッチメント部材５０を取付け、この枠状のアタッチメント部材５０に設けた開口部５１を屋外側開口部８と連通させることで、取付け部材１の屋内側において屋内側開口部１１が開口し、且つ取付け孔２の屋外側開口部８に連通するアタッチメント部材５０の開口部５１が取付け部材１の屋外側において開口されるものである。なお、このアタッチメント部材５０の開口部５１の大きさは前述の実施形態における屋外側開口部８と同じ大きさに設定するのが好ましい。
【００５４】
図１６、図１８、図２１（ａ）に示すように、枠状をしたアタッチメント部材５０の屋内側面には屋外側開口部８に対応する部位に屋外側開口部８を囲むように位置決め用当たり部５５となる突起が設けてある。また、アタッチメント部材５０の屋内側面の上記位置決め用当たり部５５よりも内周側に気密材圧接部５６が設けてある。また、図２１（ｂ）、（ｃ）に示すように、アタッチメント部材５０の外周部には化粧カバー係止部５７が設けてある。
【００５５】
コントローラユニット７の外殻を構成するハウジング１７は前述の実施形態で述べたように本体部９と、本体部９の屋外側端部に突設した屋外側突出部１０と、本体部９の屋内側端部に設けた巾広部１２とで構成してある。本体部９の外形の大きさは取付け孔２の屋外側開口部８よりも大きく且つアタッチメント部材５０の開口部５１よりも小さい大きさとなっており、この本体部９の屋外側面に外形の大きさがアタッチメント部材５の開口部５１よりも小さい屋外側突出部１０を突設してあり、本体部９の屋内側端部に外形の大きさが取付け孔２の屋内側開口部１１よりも大きい巾広部１２を形成してある。
【００５６】
しかして本実施形態においては、コントローラユニット７の本体部９を取付け部材１の取付け孔２の屋内側開口部１１から嵌め込み、屋外側突出部１０をアタッチメント部材５０の開口部５１から屋外側に突出させる。この場合、巾広部１２が取付け部材１の屋内側面に対向するのであるが、この巾広部１２と取付け孔２の屋内側開口部１１の縁部外周の取付け部材１の屋内側端部との間に弾性を有する気密材３１を介在させた状態で、カバー２０のねじ挿入孔４０から固着具４２であるねじ具を挿入してねじ具を取付け部材１の屋内側面部に固着する（図１５、図１６参照）。この時、本体部９と屋外側突出部１０の間の段部３２をアタッチメント部材５０の開口部５１の周囲の屋内側面の位置決め用当たり部５５に当接するまでねじ具を締め付けることで取付けが完了する。このように、本体部９と屋外側突出部１０の間の段部３２をアタッチメント部材５０の開口部５１の位置決め用当たり部５５に当接していることで、取付け部材１の屋外側面からの屋外側突出部１０の突出長さが一定にでき（つまり屋外側突出部１０内に内装したアンテナ１６の取付け部材１からの突出長さが一定にでき）、また、位置決め用当たり部５５の屋内側面が屋外側開口部８の開口縁部の屋内側面とほぼ面一となっていると、前述の実施形態のようにアタッチメント部材５０を設けない場合に用いるコントローラユニット７を本実施形態のようにアタッチメント部材５０を取付けた取付け部材１に取付ける場合も取付け部材１の屋外側面からの屋外側突出部１０の突出長さが一定にできるものである。これにより検知距離の劣化が認められない最も少ない突出長さにすることができるものである。気密材３１は上記のように固着具４２を構成するねじ具を締め付けることで圧縮されてコントローラユニット７の取付け部分の気密性、断熱性、水密性を確保するものである。また、本体部９と屋外側突出部１０の間の段部３２とアタッチメント部材５０の屋内側面の気密材圧接部５６との間にも図１６、図１８に示すようにパッキンのような気密材５４が介在されてアタッチメント部材５０と屋外側突出部１０との間から水が浸入しないようになっている。したがって、取付け部材１が直接雨が降りかかる門扉のような場合であっても確実に防水できるものである。
【００５７】
ところで、本実施形態のように取付け孔２の屋外側開口部８及び屋内側開口部１１の大きさを同じ大きさとし、取付け孔２の屋外側開口部８に該屋外側開口部８よりも小さい開口部５１を有するアタッチメント部材５０を取付けたものにおいては、取付け部材１の両側面のうちどちらの面が屋外側の面となるように施工されたとしても、取付け孔２における屋外側の面となる方の屋外側開口部８にアタッチメント部材５０を取付けることで対応して上記のように、屋外側突出部１０の突出長さを一定にでき、最も突出長さが短く且つ金属製の取付け部材１に影響されることなくアンテナ部６の検知距離の劣化が認められない設計上の突出距離を確保できることになる。
【００５８】
なお、アタッチメント部材５０には図２０に示すように、化粧カバー５８の係止爪５９をアタッチメント部材５０の化粧カバー係止部５７に係止することで化粧カバー５８を取付けてアタッチメント部材５０を覆うものである。ここで、図２１（ｂ）、（ｃ）、（ｄ）、（ｅ）に示すように、コントローラユニット７の屋内側のカバー２０の外形をほぼ同じにし且つカバー２０にアタッチメント部材５０の化粧カバー係止部５７と同様の化粧カバー係止部５７’を設けることで、同一の化粧カバー５８を係止爪５９をカバー２０の化粧カバー係止部５７’に係止することで化粧カバー５８によりカバー２０を覆うように取付けることができ、共通の化粧カバー５８を屋外側、屋内側において使用できるので、コストダウンが図れるものである。
【００５９】
次に、本発明の他の実施形態を図２２乃至図２６に基づいて説明する。
【００６０】
ドア枠又は子扉又は扉又は門扉よりなる取付け部材１は厚み（屋外側面と屋内側面との間の巾）が異なる場合がある。そこで、取付け部材１の厚みが異なるものであっても対応できるようにしてある。すなわち、前述の各実施形態におけるコントローラユニット７の取付けに当たって、取付け部材１の厚みが薄い場合には図２２に示すように、カバー２０に設けた巾広部１２と取付け孔２の屋内側開口部１１の縁部外周の取付け部材１の屋内側端部との間にスペーサ部材５２を介在させた状態で巾広部１２を取付け部材１に固着具４２により固着することで取付けるものである。
【００６１】
スペーサ部材５２は図２５、図２６に示すように、外形がコントローラユニット７のカバー２０の屋外側の端部の外周形状と略同じ外周形状をした枠状をしており、屋内側の面に開口を囲むように略環状をした気密材取付け部６０’が設けてあり、この気密材取付け部６０’にはパッキンのような気密材５３が取付けてある。この気密材取付け部６０’は図２６（ｂ）に示すようなもので、図２６（ｄ）に示すようなコントローラユニット７のカバー２０の屋内側の面に設けた略環状をした気密材取付け部６０と同じ形状、大きさをしていて、カバー２０の屋内側の面に設けた気密材取付け部６０に取付ける気密材３１と同じ形状の気密材５３を使用することができるようにしている。図２６（ｃ）には気密材取付け部６０’に気密材５３を取付けた状態が示してあり、図２６（ｅ）には気密材取付け部６０に気密材３１を取付けた例を示してある。
【００６２】
スペーサ部材５２の屋内側の面には開口を囲むように略環状をしたリブ６１が突設してあり、この略環状をしたリブ６１を上記カバー２０の屋外側面に取付けた略環状をした気密材３１の屋外側面に対応するような形状をしている。また、枠状をしたスペーサ部材５２は開口の少なくとも対向する一対の対向内面に係止用リブ６２が突設してある。
【００６３】
上記のような構成の枠状をしたスペーサ部材５２は図２４のようにしてコントローラユニット７に嵌め込んでスペーサ部材５２の上記リブ６１をカバー２０の屋内側の面に設けた気密材取付け部６０に圧接させると共に係止用リブ６２をコントローラユニット７の側面に圧接することで固定する。このようにコントローラユニット７にスペーサ部材５２を取付けた状態で、前述の各実施形態において述べたように取付け部材１の取付け孔２の屋内側開口部１１からコントローラ７の本体部９を嵌め込んで、屋外側突出部１０を取付け部材１の屋外側に突出させる。スペーサ部材５２の屋外側面に設けた気密材５３を取付け部材１の屋内側面に圧接させた状態（つまり、スペーサ部材５２と取付け部材１との間に気密材５３を介在させた状態）で、カバー２０のねじ挿入孔４０から固着具４２であるねじ具を挿入してねじ具をスペーサ部材５２に設けたねじ挿通孔を挿通させて取付け部材１の屋内側面部に固着する。この時、本体部９と屋外側突出部１０の間の段部３２を取付け孔２の屋外側開口部８の縁部の屋内側面（又はアタッチメント部材５０を取付け場合には位置決め用当たり部５５）に当接するまでねじ具を締め付けることで取付けが完了する。
【００６４】
このように、スペーサ部材５２を介在することで、取付け部材１の厚みが異ったものにおいても、スペーサ部材５２を介在することで、取付け部材１に本体部９を同じ条件で取付けることができ、これにより取付け部材１の屋外側面からの屋外側突出部１０の突出長さが一定にでき（つまり屋外側突出部１０内に内装したアンテナ１６の取付け部材１からの突出長さが一定にでき）るものである。
【００６５】
そして、本実施形態のようにスペーサ部材５２を介在したものにおいて、上記のように、巾広部１２とスペーサ部材５２との間に気密材３１を介在させると共に、該気密材３１と同形状の気密材５３をスペーサ部材５２と取付け部材１との間に介在させることで、スペーサ部材５２と巾広部１２との間、スペーサ部材５２と取付け部材１との間からの水を浸入を上記気密材３１、５３により防止できて、取付け部材１が門扉の場合であっても内部に雨水が浸入しないようにできるものであって、特に、取付け部材１が門扉のように雨が直接降りかかるように防水性が問題となる場合であっても十分対応できるものである。
【００６６】
【発明の効果】
上記のように本発明にあっては、簡単な構成で、取付け部材の屋外側面からの突出長さを一定にできるものであり、これにより簡単な構成で外観が悪くならないように最も突出長さが短く且つ金属製の取付け部材に影響されることなくアンテナの検知距離の劣化が認められない設計上の突出距離を確保できるのである。

BACKGROUND OF THE INVENTION
The present invention relates to an electric lock controller unit attachment structure for attaching an electric lock controller unit to an attachment member comprising a door frame, a child door, a door, or a gate.
[0002]
[Prior art]
Conventionally, an electric lock is used for the entrance door, and the controller unit of the electric lock is conventionally attached to the wall of the building. (For example, see Patent Document 1)
When the controller unit is provided on the wall of the building in this way, the position of the controller unit is away from the door, and there is a problem that it is difficult for the user to open and close the electric lock.
[0003]
In view of this, a device has been proposed in which a control unit and a receiver are housed in a notch provided on the end surface of the door on the suspending side so that an electric lock can be easily opened and closed with a card key. (For example, see Patent Document 2)
There is also known a housing in which a reader device including an antenna is housed in a recess provided on a handle protruding from the outer surface of a door and covered with a cover. (For example, see Patent Document 3)
[0004]

[Patent Document 2]
Japanese Patent Application Laid-Open No. 11-229685
[Patent Document 3]
JP-A-8-265213
[0005]
[Problems to be solved by the invention]
In Patent Document 2 in which the control unit and the receiver are housed in a notch provided on the end surface of the door hanging side in order to facilitate the opening and closing operation of the electric lock, the antenna of the receiver is placed in the door. Since it is housed, the card key detection distance is deteriorated due to the influence of a metal door or door frame, which is not preferable.
[0006]
On the other hand, in Patent Document 3, which is a conventional example in which a reader device having an antenna is housed in a recess provided on a handle protruding from the outer surface of a door and covered with a cover, the card is affected by a metal door, a door frame, or the like. Although it is possible to eliminate the deterioration of the key detection distance, since the antenna and the reader device are provided on the handle, the handle becomes larger than necessary, and the shape of the handle is restricted to accommodate the reader device. Moreover, in this cited document 3, from the outdoor side, an electric lock can be opened and closed by a card key using an antenna built in a handle, but in order to open and close the electric lock from the indoor side, the above-mentioned is also provided on the indoor side. Separately, it is necessary to provide an indoor operation unit, and it is necessary to provide separate operation units for the outdoor side and the indoor side.
[0007]
Therefore, the inventor of the present invention has considered the one shown in FIG. 27 in the process leading to the present invention. That is, a control unit for controlling the opening and closing of the electric lock 3 and the outdoor side by forming the mounting hole 2 so as to penetrate from the indoor side to the outdoor side in the mounting member 1 composed of a door frame, a child door, a door or a gate The controller unit 7 having the antenna 16 for reading the information of the non-contact type card key and locking / unlocking by the control unit is fitted into the mounting hole 2, and the end of the controller unit 7 on the outdoor side is attached to the mounting hole 2. The wide portion 12 provided at the end of the controller unit 7 on the indoor side is fixed to the mounting member 1 with a fixing tool. And the antenna 16 is arrange | positioned inside the part protruded to the outdoor side of the said controller unit 7, and it is not influenced by the metal attachment member 1 because the antenna 16 protrudes and is located in this way. I thought about making it. In this case, in the case where the controller unit 7 is inserted through the mounting hole 2, in order to ensure airtightness, heat insulation, etc. of the mounting portion of the controller unit 7, the wide portion 12 and the indoor side surface of the mounting member 1 It is necessary to attach the wide portion 12 to the attachment member 1 with a fixing tool with the airtight material 31 interposed therebetween.
[0008]
By the way, it is better that the protruding length of the protruding portion of the controller unit 7 including the antenna 16 on the outdoor side is as short as possible. However, if the protruding length is too short, it is detected by the influence of the metal mounting member 1. Distance degradation occurs. For this reason, the protrusion length indicated by the dimension A in FIG. 27B is very important, but as described above, in order to ensure airtightness, heat insulation, etc., the wide portion 12 and the mounting member 1 When the wide portion 12 is attached to the attachment member 1 with a fixing tool with an elastic airtight material 31 interposed between the inner surface and the inner surface, the attachment member 1 of the controller unit 7 having the antenna 16 built in the tip portion. It has been found that the projecting length from the outer surface of the sheet fluctuates and the target projecting dimension cannot be achieved.
[0009]
In addition, in the case as shown in FIG. 27, a hole is formed in a part of the projecting surface of the controller unit 7 projecting to the outside side, and wiring in the controller unit 7 and electrical operation (short circuit etc.) of the control circuit are performed. There is concern about the possibility of unlocking by inducing malfunction of the electric lock 3 controller.
[0010]
Furthermore, in the thing like FIG. 27, there exists a problem that the opening edge of the outdoor side of the attachment hole 2 provided in the attachment member 1 is exposed, and an external appearance is not good.
[0011]
Further, conventionally, the controller unit having an antenna attached to the door frame or child door or door of the entrance is different from the controller unit having an antenna attached to the gate, and the door door frame or child door or There was no such thing that the one attached to the door and the one attached to the gate could be combined by a controller unit having a common antenna.
[0012]
The present invention has been made in view of the above points, and with a simple configuration, the protruding length of the antenna mounting member from the outdoor side surface can be made constant, and a part of the controller unit can be partially provided on the outdoor side. Even if it is broken, the wiring inside the controller unit and the electrical operation of the control circuit (short circuit, etc.) can be made difficult and the crime prevention effect can be enhanced. Also, the opening edge on the outdoor side of the mounting hole provided in the mounting member Controller unit equipped with an antenna that can be attached to the door frame of the entrance door, the child door, or the door, which can improve the appearance, improve the waterproofness, and can cope with the case where the thickness of the mounting member is different. To provide a controller unit mounting structure for an electric lock that can be used in common with a controller unit having an antenna attached to a gate It is intended to.
[0013]
