Description

【０００１】
【発明の属する技術分野】
本発明は、ドアチェーン又はドアガードをかけたまま、ドアを半開き状態にするドア用隙間固定具に関するものである。
【０００２】
【従来の技術】
マンションや一般住居の玄関の殆どは開き戸になっており防犯のために、図２に示すようなドアガード７や図１７に示すようなドアチェーン１２０、が使用されている。これらをかけることにより、来訪者があった際、ドアを半開きにして、その来訪者と応対し、さらに、来訪者が悪質な訪問販売者で強引に室内に入ろうとしても、ドアガード７、ドアチェーン１２０がかかっていることにより、ドアが全開しないため来訪者はドアから室内に入ることが出来ないという防犯器具であり、多くの玄関ドアに使用されている。
【０００３】
さて、前記のマンションや一般住居の玄関ドアは密封性が高いため、換気や、通風性が無く、女性や老人の一人暮らしなどの場合、玄関ドアを開けておくのは防犯上、非常に危険である。また夏の夜などの暑い中、エアコンを１日中使用して体調が悪くなる人も多く、エアコンを使用しないで、玄関ドアを開けて通風性を良くしたいことがあった。
そこでドアガード７、ドアチェーン１２０をかけたままドアを半開き状態に保持する従来技術のドア用隙間固定具（例えば特許文献１参照。）の正面図を図１６に、使用状態図を図１７に示す。
【０００４】
以下の説明で共通の機能を有する構造は同一図番を用いる。
図１６のドア用隙間固定具１１０は、ドアに固定できるように磁石が入っている取付部材１１１、球部１１３、球部１１３を揺動自在にする取付カバー１１２、球部１１３を有する基軸１１４、支持杆１１５、保護部材１１６からなっており、基軸１１４には図示しない雄ねじがあり、支持杆１１５には図示しない雌ねじがあることで支持杆１１５を回転させると、ねじにより基軸１１４と支持杆１１５の連結部の長さを変化させることができるため、ドアの半開き状態の開き幅を調整することが出来る。
【０００５】
正面図の図１６と使用状態図の図１７より、ドアチェーン１２０をかけて金属製のドア１１８をやや開いた状態で、ドア用隙間固定具１１０の取付部材１１１の磁石によりドア１１８に吸着させ、支持杆１１５を立たせ、保護部材１１６を壁面１１７に押し当てることで、ドアチェーン１２０をかけたままで、ドア１１８を半開きの状態で保持することが出来る。
また、ドアの蝶番側の隙間を固定しドアの開き幅を六通りの角度に調整できる従来技術のドアストッパー（例えば特許文献２参照。）を図１８に示す。図１８（ａ）が上面図、図１８（ｂ）が正面図、図１８（ｃ）が側面図であり。図１９に取付け状態図を示し、ドアノブ８、ドアの蝶番１１、ドア開き角度１２７である。
【０００６】
ドアの開き幅を六種類の角度に調整できるドアストッパー１３０は、本体１３１、把手上部１３３、把手下部１３４、本体１３１と把手上部１３３を図示しないピンにて連結している回転部１３２があり、本体１３１は図１８（ｂ）の回転部１３２を軸として左右４５°方向に回転し、紐１３５、ドア外枠に接着固定したフック１３６により構成され、Ａ１からＡ６はそれぞれ異なる六種類の幅がある。六種類の幅の中から一つの幅を選びドアの蝶番１１側の隙間に挿入することでドアの開き角度１２７を六通りにかえることが出来る考案である。
【０００７】
また他の従来技術で、ドアの蝶番側の隙間を固定しドアの開き幅を二通りに調整できるドアストッパー（例えば特許文献３参照。）の正面図を図２０、取付け状態図を図２１に示し、ドアノブ８、ドアの蝶番１１、ドア開き角度１３７である。
ドアの開き幅を二通りの角度に調整できるドアストッパー１４０は、顔の球状部大１４１と胴体の球状部小１４２、首１４３、紐１４４にて構成されており、ドアクローザ６に結び目１４５により紐１４４が結ばれている。この考案は球状部大１４１の大きさと球状部小１４２大きさの違いにより、ドアの蝶番１１側の隙間にそれぞれ挿入することでドアの開き角度１３７を二通りに、かえることが出来る考案である。

【発明が解決しようとする課題】
しかしながら、図１６、図１７に示すのドア用隙間固定具１１０は、金属製のドア１１８を取付部材１１１内部の磁石により吸着する仕様となっているので、取付けが簡単である反面、少し大きな力が取付部材１１１に加わった場合は、容易に脱落しドア１１８が閉まってしまうという問題がある。さらに基軸１１４は取付カバー１１２により揺動自在に動かせる構造になっている為、保護部材１１６に少し大きな力が加わって、その方向が水平からずれると、保護部材１１６に掛かる壁面１１７からの反力の垂直方向の分力によって保護部材１１６が垂直方向に傾いてしまい、ドア１１８が閉まってしまうので、やはり不安定である。
【００１０】
また、支持杆１１５を回転させることで基軸１１４と支持杆１１５の接合部長さを変えることで、ドアの開き幅を調整することが出来るが、支持杆１１５の一回転は、ねじの一ピッチぶんの長さしか変えられないため、数センチほどドアの開き幅を調整する場合は支持杆１１５を何回も回転させなければならず、容易に開き幅を調整できないという問題があった。
また、図１８、図１９に示す六種類の角度に調整できるドアストッパー１３０は、ドアガード７、ドアチェーン１２０をかけたままでは、ドアの蝶番１１側の隙間は殆ど無いため、Ａ１からＡ６の挿入部を挿入することが出来ない。またドアの開き角度１２７を六種類にかえるため、Ａ１からＡ６の六種類の異なる幅を必要とするので、複雑な形状になり、コスト高になってしまう問題があった。
【００１１】
また、回転部１３２があるため本体１３１が容易に動いてしまい、蝶番１１側の隙間に挿入する時に挿入しずらく、子供や老人は蝶番１１側の隙間に指をはさむ危険がある。特にドアノブ８側の力を力点、蝶番１１を支点、蝶番１１側の隙間に加わる力を作用点とした時、てこの原理により、ドアノブ８側の力より蝶番１１側の隙間に加わる力が大きくなるため、蝶番１１側の隙間に指をはさむと大変危険であるという問題があった。
また、図２０、図２１に示す二通りの角度に調整できるドアストッパー１４０は、ドアガード７、ドアチェーン１２０をかけたままでは、ドアの蝶番１１側の隙間は殆ど無いため、挿入することが出来ない。またドアの開き角度１３７を二通りにかえるため複雑な形状になり、コスト高になってしまう問題がある。
【００１２】
また、蝶番１１側の隙間に球状部大１４１を挿入する時は、球状部小１４２を把持して挿入するが、首１４３の長さ１４６が２０ｍｍと短いため少し指を動かすと蝶番１１側の隙間に指をはさむ危険があるという問題がある。
さらにドア用隙間固定具１１０、六種類の角度に調整できるドアストッパー１３０、二通りの角度に調整できるドアストッパー１４０とも外から不審者などがドアを開けようとした場合に不審者や部屋の中いる人に警告する手段は有していない。
【００１３】
本発明の目的は、かかる従来技術の問題を解決し、挿入部形状が単純な形状でドアの開き幅をかえることができ、本発明の他の目的は挿入部をドアに挿入する時に指をはさまないように安全性が高く、また他の目的は、外からドアを開けようとした場合に警告する手段を有することで防犯上、より安全なドア用隙間固定具を提供するものである。
【００１４】
【課題を解決するための手段】
本発明は、上記の課題を解決することを目的としてなされたもので、請求項１に記載したドアチェーン又はドアガードをかけたまま、ドアを半開き状態にするドア固定具において、ドア上面の隙間に差込む棒状の挿入部と該挿入部の長さより長い握り部を有する吊り下がり部は、連結部により該吊り下がり部の床への落下を防止する落下防止部に連結されていることを特徴とするドア用隙間固定具からなる。
【００１５】
請求項１に記載した本発明は上記構成により、ドアチェーン又はドアガードをかけたままでも、ドア上面の間に挿入部を挟むだけで、挿入部が固定されドアを半開き状態に出来る。
また、挿入部は紐などの連結部によりドアにあらかじめ固定された吸盤などの落下防部に連結されている為、床に落下することが無いので、立ったまま容易に取外しができる効果がある。また、挿入部に握り部を有することで、ドアと壁の隙間に差し込む挿入部を直接手で触らないので、ドアと壁の隙間に指をはさみ込むことが無く、安全に使用できるという効果がある。また挿入部を固定している握り部を長くすることで、ドア上面が高い位置にあっても容易にドア上面に挿入部を挟み込むことができるという効果もある。
【００１６】
請求項２に記載した該挿入部の外径より大きい外径の挿入位置決め部が該挿入部と該握り部の間に固定されていることを特徴とした請求項 1 に記載のドア用隙間固定具からなる。
請求項２に記載した本発明は、図１２の挿入位置決め部６０があることで、挿入部となるウレタンゴム部５２をドア９と壁１０の隙間に挿入する場合、ウレタンゴム部５２の外形より挿入位置決め部６０の外形が大きいため、挿入位置決め部６０がドア９と壁１０の隙間にあたり、挿入位置決め部６０は挿入できないのでウレタンゴム部５２を挿入しすぎることが無く適切な位置でウレタンゴム部５２を挿入できるという効果がある。
【００１７】
請求項３に記載した該挿入位置決め部に振動で音が発生する警告手段がぶら下がり、該警告手段に隣接する位置の握り部に金属部が固定されていることを特徴とした請求項 2 に記載のドア用隙間固定具からなる。
請求項３に記載した本発明は、図１２の挿入部となるウレタンゴム部５２に円盤状の挿入位置決め部６０が固定され、挿入位置決め部６０に紐５７が複数固定され、紐５７の下に、パイプ５８がぶらさがっている、挿入位置決め部６０の下面には握り部となる丸棒５６が固定され、パイプ５８に隣接する位置に円筒状の金属部５９の内径が丸棒５６の外形に挿入された状態で固定されている。この構成で本体部に振動が加わると紐５７にぶら下がっているパイプ５８がゆれて金属部５９やパイプ５８どうしが接触して音を発するという効果がある。
さらに、不審者などがドアを開けようとした場合やドアチェーン又はドアガードを切断して入り込もうとした場合など、ドアをあける方向に動かすと、ドアに挟み込んだ挿入部が落下して振動する、その振動を感知して警告する警告手段により、部屋の内部の人や、不審者に警告するので、防犯上の安全性が向上するという効果がある。
【００２６】
【発明の実施の形態】
本発明のドア用隙間固定具の実施例１を図１〜図６に示す。
図１はドア用隙間固定具の正面図。
図２はドアを閉めた状態での図１の使用状態図。
図３はドアを半開きにした状態での図１の使用状態図
図４は図３のＺ方向から見たドアの開き幅が大きい断面図。
図５は図３のＺ方向から見たドアの開き幅が小さい断面図。
図６はＦ１方向にドアを開いた時に図３のＺ方向から見た断面図である。
【００２７】
図１は、本発明の実施例１の挿入部からなるドア用隙間固定具１であり、挿入部となる円柱形状の円柱部２は、例えば、ウレタンゴムであり、また円柱部２の中央に貫通穴３があり、連結部となる紐４を貫通穴３に通して円柱部２に結び付け、さらに紐４を落下防止部となる吸盤５に結び付けている。
図２は挿入部からなるドア用隙間固定具１を玄関ドアの室内側のドア９に吸盤５により吸着して吊り下げた状態図であり、ドアクローザ６、ドアガード７、ドアノブ８、壁１０、蝶番１１、床１４である。ドアクローザ６はドア９を閉める方向にゆっくりと力を加えることで、ドア９の急激な開閉を防止しドアの指はさみを防ぐ安全装置である。
【００２８】
図３はドアガード７をかけた状態で、挿入部からなるドア用隙間固定具１の円柱部２をドア９の上面と壁１０の隙間に挟み込み、ドアを半開きにした使用状態図であり、ドアクローザ６、ドアノブ８、蝶番１１、床１４である。
図４は図３のＺ方向から見た断面図であり、蝶番１１側の方向に円柱部２を挟み込むとドアの開き幅１２が大きくなる。
図５は図３のＺ方向から見た断面図であり、ドアノブ８側の方向に円柱部２を挟み込むとドアの開き幅１３が小さくなる。このように円柱部２の形状を複雑な厚みで構成しなくても、ドア上面の挟み込む位置によりドアの開き幅を調整することが出来るという効果がある。
【００２９】
図６は図３のＺ方向から見た断面図であり円柱部２をドア９が開く方向の力Ｆ１によりドアを開くとドア９と壁１０に挟まれていた円柱部２に隙間ができる位置に挿入することで、ドアを開くと自重により円柱部２が落下して外れる図であり、ドア９を開くことで容易に円柱部２を外すことが出来る。また挿入部の形状を、棒状、蒲鉾状、角柱状、板状、挿入方向が小さく反挿入方向が大きい形状となる、円錐状、角錐状、くさび形状にすると、ドア９を開いたときの少しの隙間でも挿入部が、ドア９と壁１０に引っかからず、容易に外れるという効果がある。挿入部は弾性体でありゴム材質やプラスチック材質または、プラスチック材質からなる弾性構造体、例えば板ばね形状などでもよい。挿入部が弾性体なのでドア９と壁１０の隙間に挿入しても、ドア９や壁１０を傷つけることが無いという効果がある。
【００３０】
また、挿入部が例えばウレタンゴムの場合は、色が黒い為、玄関に吊るすと見栄えが良くない、この場合は挿入部にカラフルな布や皮を付けることでデザイン性が向上する、特に季節に合わせた布や皮の袋を挿入部に被せたり、布や皮を巻きつけたり、貼り付けることで、玄関の雰囲気にあったデザインが容易に出来る。連結部は紐または鎖形状でも良く、連結部の材質はゴム材質、皮材質、プラスチック材質、繊維材質となる麻、絹、綿などであり、連結部がドア９や壁１０に挟まれてもドア９や壁１０に傷をつけない効果がある。
落下防止部は連結部をドア９や壁１０に固定する構造であり、たとえば紐４を結び固定するフックや、紐４を結び付ける穴のある構造体などを吸盤、磁石、接着テープ、接着剤、ねじ、釘によりドア９や壁１０固定または吸着する。
【００３１】
落下防止部の固定方法は、ドア９又は壁１０の材質に適した固定方法を選択する、例えば凹凸の無いスチール製のドアに吸着する場合は吸盤や磁石がよく、ドアに傷をつけないという効果がある。
また吸盤や磁石で固定できない凹凸のある木製のドアや壁は接着テープ、接着剤、ねじ、釘により固定することで確実に落下防止部を固定できる。また落下防止部は連結部の長さを調節できるようになっている。たとえば紐４を所望の長さに調整し貫通穴３と吸盤５に結び付けることで落下距離を調整することができるので、円柱部２の落下時に人や物にぶつからない長さに調整できるという効果がある。
【００３２】
また、挿入部となる円柱部２や連結部となる紐４に図示しない警告手段となる、ベルや鈴などを取付けることで図６に示すように、ドアを開けた時の円柱部２の落下による振動で音が鳴るので、不審者がドアを開けた場合に警告するという効果があり。
さらにドアチェーン又はドアガードをかけない状態でドアを開閉する時でもドア開閉の振動で円柱部２や紐４が揺れて、ベルや鈴が鳴るので人がドアを開閉したことを知らせることができるという効果もある。
【００３３】
本発明の実施例２を、図７、図８、図９、図１０に示す。
図７は実施例２の正面図。図８はドアガード７をかけた状態でドアを半開きにした実施例２の使用状態図。図９はドアが閉まった状態での実施例２の使用状態図。図１０はドアノブ側のドア側面の隙間に挿入部を差込んだ実施例２の使用状態図である。
図７は挿入部と握り部からなるドア用隙間固定具２１に、警告手段がある構成であり、挿入部となる棒状のウレタンゴム部２２、握り部となる丸棒２６、紐２７、警告手段となる鈴２８、連結部となる紐２４、落下防止部となる吸盤２５、吊り下がり部２９、接続部２３である。
【００３４】
図７で示すように吸盤２５に結ばれた紐２４に吊り下がる、吊り下がり部２９は円柱形状のウレタンゴム部２２、丸棒２６、紐２７、鈴２８で構成される。図８はドアガード７をかけた状態で挿入部と握り部からなるドア用隙間固定具２１によりウレタンゴム部２２をドア９と壁１０の隙間に挟み、ドアを半開きにした状態図であり、ドアクローザ６、ドアノブ８、壁１０、蝶番１１、床１４である。ドアクローザ６はドア９を閉める方向にゆっくりと力を加えることで、ドア９の急激な開閉を防止しドアの指はさみを防ぐ安全装置である。
図９はドアの外側から不審者などがドアを少し開けて、ドア９と壁１０の隙間が広がり、ウレタンゴム部２２が外れ、吊り下がり部２９が落下し、吸盤２５に結ばれた紐２４により吊り下がり部２９が吊るされる。その後、ドアクローザ６によりドア９が閉じた状態図である。
【００３５】
このように吊り下がり部２９が落下による振動を受けると鈴２８が鳴り、部屋の中にいる人に、ドアを開けたことを知らせることが出来るという効果がある。
さらにドアチェーン又はドアガードをかけない状態でドアを開閉する時でもドア開閉の振動で吊り下がり部２９や紐２４が揺れて、鈴が鳴るので人がドアを開閉したことを知らせることができるという効果もある。
また、吊り下がり部２９は連結部となる紐２４に吊るされ、接続部２３は吊り下がり部２９の重心より挿入部側に位置することで図９に示すように握り部となる丸棒２６が下側に垂れ下がるので握り部が低い位置になり、背の低い人や子供でも握り部が持ちやすい位置になるという効果がある。
【００３６】
挿入部は弾性体でありゴム材質やプラスチック材質または、プラスチック材質からなる弾性構造体、例えば板ばね形状などが好ましい、挿入部が弾性体なのでドア９と壁１０の隙間に挿入しても、ドア９や壁１０を傷つけることが無いという効果がある。
また挿入部が例えばウレタンゴム部の場合は、色が黒い為、玄関に吊るすと見栄えが良くない、この場合は挿入部にカラフルな布や皮を付けることでデザイン性が向上する、特に季節に合わせた布や皮の袋を挿入部に被せたり、布や皮を巻きつけたり、貼り付けることで、玄関の雰囲気にあったデザインが容易に出来る。さらに挿入部に図示しない花、鳥、動物形状のデザインを施すことで、インテリアとしても良好なドア用隙間固定具ができる。
【００３７】
握り部は挿入部を固定し握りやすい構造であり、握り部と挿入部は同一材質から構成されている一体形状でも良い、一体形状にする場合は部品点数が減りコストダウンできる。また握り部と挿入部を別材料の部品としても良い、別材料の部品の場合は、たとえば握り部を木材又はプラスチック材質のパイプにすることで軽量化できるため、吊り下がり部の落下時の衝撃が少なくなり、落下防止部に加わる衝撃を軽減させることで落下防止部の吸着力が少ない吸盤や磁石でも安定して固定できるという効果がある。
また握り部を挿入部より長くすることで、挿入部をドア９と壁１０の隙間挿入するときに手や指をドア９と壁１０の隙間に挟むこことが無くより安全に使用できるという効果もある。
【００３８】
連結部は紐または鎖形状でも良く、連結部の材質はゴム材質、皮材質、プラスチック材質、繊維材質となる麻、絹、綿などが良く、連結部がドア９や壁１０に挟まれてもドア９や壁１０に傷をつけないという効果もある。
落下防止部は連結部をドア９や壁１０に固定する構造であり、たとえば紐２４を結び固定するフックや、紐２４を結び付ける穴のある構造体などを吸盤、磁石、接着テープ、接着剤、ねじ、釘によりドア９や壁１０固定または吸着する。
落下防止部の固定方法は、ドア９又は壁１０の材質に適した固定方法を選択する、例えば凹凸の無いスチール製のドアに吸着する場合は吸盤や磁石がよく、ドアに傷をつけないという効果がある。
また吸盤や磁石で固定できない凹凸のある木製のドアや壁は接着テープ、接着剤、ねじ、釘により固定することで確実に落下防止部を固定できる。
また落下防止部は連結部の長さを調節できるようになっている。
たとえばウレタンゴム部２２の端面に固定されている紐２４を所望の長さに調整し吸盤２５に結び付けることで落下距離を調整することができるので、吊り下がり部２９の落下時に人や物にぶつからない長さに調整できるという効果がある。
【００３９】
図１０はドアノブ側のドア側面の隙間に挿入部を差込んだ使用状態図であり、背の低い子供などドア上面の隙間に挿入部を差し込むことが出来ない場合は、ドアノブ８の近辺に落下防止部となる吸盤２５を吸着すると低い高さでも、ドア９のドアノブ側と壁１０の隙間に挿入部を差込むことで、ドアを半開きにすることが出来るという効果がある。
【００４０】
図１１は本発明の実施例３であり、挿入部と握り部からなるドア用隙間固定具３１に、警告手段がある構成であり、挿入部となるウレタンゴム部３２、握り部となる筒３６、丸棒３７、筒３６と丸棒３７を固定するストッパー３９であり、連結部となる紐３４、警告手段となる鈴３８、落下防止部となる吸盤３５である。また吸盤３５に結ばれた紐３４に吊り下がる、吊り下がり部４０はウレタンゴム部３２、丸棒３７、筒３６、ストッパー３９で構成される。
ウレタンゴム部３２は挿入方向が小さく反挿入方向が大きい楔形状であるので、ドア９の上面側と壁１０の隙間に挿入しやすい。
また丸棒３７は筒３６内部に入る構造で、ストッパー３９を回転させて緩めると、丸棒３７と筒３６の長さを変えることが出来、使用しやすい長さに調整後、ストッパー３９を逆回転させて締め付けることで、丸棒３７と筒３６の長さを固定することが出来るので。ドア上面の高さが高いドアや低いドアでも、容易に握り部長さを調整できるので使いやすいという効果がある。
【００４１】
図１２は本発明の実施例４であり、挿入部と握り部からなるドア用隙間固定具５１に、警告手段がある構成であり、挿入部となるウレタンゴム部５２、握り部となる丸棒５６、紐５７、金属棒となるアルミ製のパイプ５８、金属部５９、挿入位置決め部６０、連結部となる紐５４、落下防止部となる吸盤５５である。吊り下がり部４１は紐５４で吊るされた部分であり、円柱状のウレタンゴム部５２に円盤状の挿入位置決め部６０が固定され、挿入位置決め部６０に紐５７が複数固定され、紐５７の下に、パイプ５８がぶらさがっている、挿入位置決め部６０の下面には丸棒５６が固定され、パイプ５８に隣接する位置に円筒状の金属部５９の内径が丸棒５６の外形に挿入された状態で固定されている。この構成で本体部に振動が加わると紐５７にぶら下がっているパイプ５８がゆれて金属部５９やパイプ５８どうしが接触して音を発するという効果がある。
また、挿入位置決め部６０があることで、ウレタンゴム部５２をドア９と壁１０の隙間に挿入する場合、ウレタンゴム部５２の外形より挿入位置決め部６０の外形が大きいため、挿入位置決め部６０がドア９と壁１０の隙間にあたり、挿入位置決め部６０は挿入できないのでウレタンゴム部５２を挿入しすぎることが無く適切な位置でウレタンゴム部５２を挿入できるという効果がある。
【００４２】
図１３は本発明の実施例５であり、挿入部と握り部からなるドア用隙間固定具６１に、警告手段がある構成であり、挿入部となるウレタンゴム部６２、握り部となる丸棒６６、連結部となる紐６４、落下防止部となる吸盤６５、警告手段となる警告手段部６９、電源スイッチ６７、警告光を発する発光ダイオード７０、警告音を発するスピーカ６８、があり警告手段部６９の内部は図示しない電池、振動センサー、制御回路がある。
【００４３】
挿入部となるウレタンゴム部６２をドア９と壁１０に挟み込み、ドア９を半開き状態にしているときに、ドア９を図６のＦ１方向に開くと、吊り下がり部７１が落下することで、警告手段部６９内部の振動センサーにより振動を感知し、スピーカ６８と発光ダイオード７０により警告音と警告光を発するので、室内にいる人に、ドアが開いたことをしらせることができる。また振動センサーからの信号を受信した後、制御回路により、一定時間音と光を発することにより、振動している時間が短くても、一定時間音と光を発するので、室内にいる人が確実に警告音または警告音と警告光を確認できるという効果がある。
【００４４】
図１４は本発明の実施例５の変形例であり、挿入部と握り部からなるドア用隙間固定具８１に、警告手段がある構成であり、挿入部となるウレタンゴム部８２、握り部となる丸棒８６、連結部となる紐８４、落下防止部を固定する内部に磁石がある吸着板８５、警告手段となる警告手段部８９、電源スイッチ８７、警告光を発する発光ダイオード９０、警告音を発するスピーカ８８、紐８４が接続されている振動感知部７２があり警告手段部８９の内部は図示しない電池、振動センサー、制御回路部がある。
【００４５】
挿入部となるウレタンゴム部８２をドア９と壁１０に挟み込み、ドア９を半開き状態にしているときに、ドア９を図６のＦ１方向に開くと吊り下がり部７３が落下することで、振動感知部７２に振動が伝わり、警告手段部８９内部の振動センサーにより振動を感知し、発光ダイオード９０とスピーカ８８により警告音と警告光を発することで、室内にいる人に、ドアが開いたことを知らせることができる。また振動センサーからの信号を受信した後、制御回路により、一定時間音と光を発することにより、振動している時間が短くても、一定時間音と光を発するので、室内にいる人が確実に警告音または警告音と警告光を確認できるという効果がある。
【００４６】
図１５は本発明の実施例６であり、挿入部と握り部からなるドア用隙間固定具９１に、警告手段がある構成であり、挿入部となる円柱状のウレタンゴム部９２、握り部となる丸棒９６、連結部となる紐９４、落下防止部を固定する内部に磁石がある吸着板９５、警告手段は振動送信部１０２と警告部１０３からなり、振動送信部１０２は電源スイッチ９７、紐９４が接続されている振動感知部９９があり、内部は図示しない電池、振動センサー、制御回路部、信号送信部がある。警告部１０３は電源スイッチ１０１、警告光を発する発光ダイオード１００、警告音を発するスピーカ９８、があり内部は図示しない電池、振動送信部１０２の電波からの信号を受信する信号受信部、信号より、一定時間発光ダイオード１００とスピーカ９８に電流を流すタイマー回路部がある。
【００４７】
挿入部となるウレタンゴム部９２をドア９と壁１０に挟み込み、ドア９を半開き状態にしているときに、ドア９を図６のＦ１方向に開くと吊り下がり部１０４が落下することで、振動感知部９９に振動が伝わり、振動センサーにて振動を感知し、制御回路部にて信号にして、信号送信部により電波にてデータを警告部１０３に送る。警告部１０３は信号受信部にて受信した電波を電気信号に変換し、タイマー回路部によりあらかじめ設定した時間や音色により発光ダイオード１００とスピーカ９８に電流を流す。
また振動送信部１０２からの信号は電気コードにて警告部１０３に送っても良い。
振動送信部１０２と警告部１０３をはなれた場所に設置させる構成とすることで、玄関ドアから離れた場所や離れた部屋にいた場合など、警告音が聞こえない場合は、警告部１０３を人の近辺に設置すれば警告音が聞き取れるという効果がある。
【００４８】
【発明の効果】
以上詳しく説明したように、ドアチェーン又はドアガードをかけたままでも、ドアクローザによりドアを閉める壁側方向に力が働く為、ドア上面又はドアノブ側のドア側面と壁の間に挿入部を挟むだけで、挿入部が固定されドアを容易に半開き状態に出来るという効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a door gap fixing tool that places a door in a half-open state while a door chain or a door guard is applied.
[0002]
[Prior art]
Most of the entrances of condominiums and general houses are hinged doors, and a door guard 7 as shown in FIG. 2 and a door chain 120 as shown in FIG. 17 are used for crime prevention. By applying these, when there is a visitor, the door is opened half-way to deal with the visitor, and even if the visitor tries to forcibly enter the room as a malicious visitor, door guard 7 and door chain Since the door 120 is open, the door is not fully opened, and thus a visitor cannot enter the room through the door, and is used for many entrance doors.
[0003]
Well, the entrance doors of the apartments and ordinary houses have high sealing performance, so there is no ventilation or ventilation, so it is very dangerous to keep the entrance door open for women and elderly people living alone. is there. In addition, many people use the air conditioner throughout the day during hot summer nights and feel unwell, and instead of using the air conditioner, they wanted to open the entrance door to improve ventilation.
Accordingly, FIG. 16 shows a front view of a conventional door gap fixing tool (see, for example, Patent Document 1) that holds the door in a half-opened state with the door guard 7 and the door chain 120 applied, and FIG. 17 shows a state of use. .
[0004]
In the following description, the same number is used for a structure having a common function.
A door gap fixing tool 110 shown in FIG. 16 has a mounting member 111 containing a magnet so that it can be fixed to the door, a sphere 113, a mounting cover 112 that allows the sphere 113 to swing, and a base shaft 114 that includes the sphere 113. The base shaft 114 has a male screw (not shown), and the support rod 115 has a female screw (not shown). When the support rod 115 is rotated, the base shaft 114 and the support rod are rotated by the screw. Since the length of the connecting portion 115 can be changed, the opening width of the door in the half-open state can be adjusted.
[0005]
From the front view of FIG. 16 and the usage state diagram of FIG. 17, the door 118 is made to be attracted to the door 118 by the magnet of the mounting member 111 of the door gap fixing tool 110 with the door chain 120 being slightly opened. The door 118 can be held in a half-open state while the door chain 120 is applied by raising the support rod 115 and pressing the protective member 116 against the wall surface 117.
FIG. 18 shows a conventional door stopper (see, for example, Patent Document 2) that can fix the gap on the hinge side of the door and adjust the opening width of the door to six angles. 18A is a top view, FIG. 18B is a front view, and FIG. 18C is a side view. FIG. 19 shows an attachment state diagram, which shows the door knob 8, the door hinge 11, and the door opening angle 127.
[0006]
The door stopper 130 that can adjust the opening width of the door to six kinds of angles includes a main body 131, a handle upper portion 133, a handle lower portion 134, and a rotating portion 132 that connects the main body 131 and the handle upper portion 133 with a pin (not shown). The main body 131 is composed of a string 136 and a hook 136 bonded and fixed to the door outer frame with the rotating portion 132 of FIG. 18B as an axis and rotating in the left and right directions, and A1 to A6 have six different widths. is there. It is a device that can change the opening angle 127 of the door in six ways by selecting one of the six widths and inserting it into the gap on the hinge 11 side of the door.
[0007]
FIG. 20 is a front view of a door stopper (see, for example, Patent Document 3) that can adjust the opening width of the door in two ways by fixing the gap on the hinge side of the door, and FIG. The door knob 8, the door hinge 11, and the door opening angle 137.
The door stopper 140 which can adjust the opening width of the door to two angles is composed of a large spherical portion 141 of the face, a small spherical portion 142 of the body, a neck 143 and a string 144, and a string 145 is connected to the door closer 6 by a knot 145. 144 is tied. According to this device, the opening angle 137 of the door can be changed in two ways by inserting each into the gap on the hinge 11 side of the door due to the difference between the size of the large spherical portion 141 and the size of the small spherical portion 142. .

[Problems to be solved by the invention]
However, since the door gap fixture 110 shown in FIGS. 16 and 17 is designed to attract the metal door 118 by the magnet inside the mounting member 111, the mounting is easy, but a little large force is required. Is attached to the mounting member 111, there is a problem that the door 118 is easily dropped and the door 118 is closed. Further, since the base shaft 114 is structured so as to be swingable by the mounting cover 112, if a slightly large force is applied to the protection member 116 and the direction deviates from the horizontal, the reaction force applied to the protection member 116 from the wall surface 117. Since the protective member 116 is inclined in the vertical direction due to the vertical component force, the door 118 is closed, which is also unstable.
[0010]
In addition, the opening width of the door can be adjusted by changing the joint length between the base shaft 114 and the support rod 115 by rotating the support rod 115. However, one rotation of the support rod 115 is equivalent to one pitch of the screw. Therefore, when adjusting the opening width of the door by several centimeters, the support rod 115 has to be rotated many times, and the opening width cannot be easily adjusted.
The door stopper 130 that can be adjusted to six angles shown in FIGS. 18 and 19 has almost no gap on the hinge 11 side of the door when the door guard 7 and the door chain 120 are applied. The part cannot be inserted. Further, since the door opening angle 127 is changed to six types, six different widths A1 to A6 are required, so that there is a problem that the shape becomes complicated and the cost is increased.
[0011]
In addition, the main body 131 easily moves because of the rotating portion 132, and it is difficult to insert the main body 131 into the gap on the hinge 11 side, and there is a risk that a child or an elderly person may pinch a finger in the gap on the hinge 11 side. In particular, when the force on the doorknob 8 side is the force point, the hinge 11 is the fulcrum, and the force applied to the gap on the hinge 11 side is the point of action, the force applied to the gap on the hinge 11 side is greater than the force on the doorknob 8 side by the lever principle. Therefore, there is a problem that it is very dangerous to put a finger in the gap on the hinge 11 side.
The door stopper 140 that can be adjusted to two angles shown in FIGS. 20 and 21 can be inserted because there is almost no clearance on the hinge 11 side of the door with the door guard 7 and the door chain 120 applied. Absent. Further, since the door opening angle 137 is changed in two ways, there is a problem that the shape becomes complicated and the cost becomes high.
[0012]
In addition, when inserting the large spherical portion 141 into the gap on the hinge 11 side, the small spherical portion 142 is gripped and inserted, but the length 146 of the neck 143 is as short as 20 mm, so if you move your finger slightly, There is a problem that there is a danger of putting a finger in the gap.
Furthermore, the door gap fixing tool 110, the door stopper 130 that can be adjusted to six different angles, and the door stopper 140 that can be adjusted to two different angles can be used when a suspicious person or the like attempts to open the door from the outside. I don't have a way to warn someone.
[0013]
The object of the present invention is to solve the problems of the prior art and to change the opening width of the door with a simple shape of the insertion portion. Another object of the present invention is to insert a finger when inserting the insertion portion into the door. It is safe so that it does not get caught, and another object is to provide a safer door gap fixing device for crime prevention by having means for warning when the door is opened from the outside. .
[0014]
[Means for Solving the Problems]
The present invention has been made for the purpose of solving the above-described problems.
