前記目的に沿う第 1の発明に係る ドアのオートロック装置は、 開閉可 能なドアを内側に備えたドア枠に設けた掛け金と、 ドアに回動ピンを介 して揺動可能に取付けられ、 掛け金に掛合可能なロックアームとを備え たドアのォートロック装置であって、 口ックアームを揺動させるロック ァ一ム駆動機構と、 ロックアームの施錠状態及び解錠状態をそれぞれ検 出する施錠センサー及び解錠センサ一と、 ドアの開閉状態を検出する ド ァセンサ一と、 施錠センサー及びドアセンサーの出力に応じて口ックァ —厶が施錠状態で、 かつドアが半開状態であることを知らせるブザーと 、 ドアの内側に設けて口ックアームを解錠状態にする解錠指合を O N— O F F信号と暗証番号の少なく とも一方により入力するキー入力手段と 、 キー入力手段からの所定の信号及びドアセンサーがドアの閉状態を検 知した信号を確認してロックアームを解錠状態にする信号を口ックァ一 ム駆動機構に送り、 また、 ドアが開いた状態から閉じた場合に作動する ドアセンサーの信号を確認して、 口ックァ一厶駆動機構にロックアーム を施錠状態にする信号を送る制御装置とを有する。 According to a first aspect of the present invention, there is provided a door auto-locking device comprising: a latch provided on a door frame provided with an openable / closable door inside; and a swingably attached to the door via a pivot pin. A lock arm drive mechanism for swinging the lock arm, and a lock sensor for detecting the lock state and the unlock state of the lock arm, respectively. An unlock sensor, a door sensor for detecting the open / closed state of the door, and a buzzer for notifying that the lock is locked and the door is half-opened according to the outputs of the lock sensor and the door sensor. A key input means is provided inside the door to input an unlocking signal for unlocking the lock arm by using at least one of an ON-OFF signal and a password. A predetermined signal from the key input means and a signal from the door sensor detecting the closed state of the door are confirmed, and a signal for unlocking the lock arm is sent to the mouth cam drive mechanism, and the door is opened. And a control device that checks a signal from a door sensor that operates when the door is closed from the closed state, and sends a signal to the lock drive mechanism to lock the lock arm.
これにより、 ロックアームが施錠状態にあるときに、 外部の人が外側 (又は内側） からドアを開けようとすると、 ドアは半開状態までしか開 かず、 そのままの状態が続く と異常を知らせるブザーが鳴る。 そこで、 内部の人が安全を確認した後、 ドアの内側に設置しているキー入力手段 から暗証番号などの所定の解錠を指合する信号を制御装置に送る。 そし て、 外部の人又は内部の人が一旦ドアを閉じることで、 ドアセンサーか らドアの閉状態を検知した信号を制御装置に送り、 制御装置はドアの閉 状態を検知した信号を確認してブザーを停止させ、 ロックアーム駆動機 構により口ックアームを解錠状態にする。 この伏態で外部の人はドアを 開く ことが可能となる。 また、 ドアを閉じたときには、 ドアセンサ一の ドアの閉状態を検知した信号が制御装置に送られ、 口ックアーム駆動機 構を介して自動的にロックアームを施錠状態に復帰することができる。 ここで、 ロックァ一厶駆動機構は一方向回転モータと、 一方向回転モ 一夕の出力軸に固定された回転板と、 回転板に偏心して設けたクランク ピンと、 ロックアームの中間部に設けた連結ピンと、 連結ピンとクラン クピンとにそれぞれ両端が回動自在に連結された連結バーとを備えても よい。  As a result, if an outside person attempts to open the door from outside (or inside) while the lock arm is locked, the door will only open to the half-open state, and a buzzer will notify the user of an abnormality if the door remains open. Sounds. Therefore, after a person inside confirms safety, a signal indicating a predetermined unlocking such as a personal identification number is transmitted to the control device from the key input means installed inside the door. Then, when an outside person or an inside person closes the door, the door sensor sends a signal indicating that the door is closed from the door sensor to the controller, and the controller checks the signal indicating that the door is closed. To stop the buzzer, and unlock the lock arm by the lock arm drive mechanism. In this prone state, outsiders can open the door. Further, when the door is closed, a signal indicating that the door sensor is closed is sent to the control device, and the lock arm can be automatically returned to the locked state via the lock arm driving mechanism.

In this state, the person who is outside (or inside) the door enters the unlocked state by keying in a predetermined unlocking signal such as a certification number into the key input means installed inside the door. Send a signal to the controller. Once the door is closed, the buzzer is stopped and the sliding arm is unlocked by the lock mechanism with the confirmation signal that the door is closed. In this state, the outside person can open the door. Also, when the door is closed, a signal that the door sensor detects the closed state of the door is sent to the control device, and the sliding arm can be automatically locked by the control device. If the door is not opened even after the unlocked state has passed for a predetermined time, the controller automatically returns the sliding arm to the locked state.
ここで、 掛け金には番号鍵が設けられ、 掛け金が番号鍵の操作によつ て分解されてチェーンから脱着が可能となっているものでもよい。 この場合、 非常時にキー入力手段の暗証番号を知らない、 例えばビル やマンションの管理人など安全な人が半開状態のドアの隙間から番号鍵 を操作してチェーンから掛け金を外し、 ドアを自由に開閉可能にするこ とが出来る。  Here, the latch may be provided with a number key, and the latch may be disassembled by the operation of the number key so as to be detachable from the chain. In this case, in case of emergency, a safe person such as a building or condominium manager who operates the number key through the gap in the half-opened door, removes the latch from the chain, and can freely open the door It can be opened and closed.

このように、 ドアのオートロック装置 1 0は、 その構成要素を全てド ァ 2 1の内側に取付けているので、 ドア 2 1の外側からは見えず、 ドア 2 1の外観を損することもなく、 ドアのオートロック装置 1 0の存在が 判り難いので、 不当な行為によって破損されることもなく、 室内の安全 を確保することができる。  As described above, since the door auto-locking device 10 has all its components mounted inside the door 21, it cannot be seen from the outside of the door 21 and does not impair the appearance of the door 21. However, since the presence of the door auto-lock device 10 is difficult to recognize, it is possible to ensure the safety of the room without being damaged by unjust acts.
また、 電源 5 1に電池を使用しているので外部配線が不要であり、 ド ァのォ一トロック装置 1 0の取付けが簡単である。 ここで本実施例に係る ドアのォー卜ロック装置 1 0の解錠動作につい て図 2に示すフローチヤ一トに基づいて説明する。 Further, since a battery is used for the power supply 51, no external wiring is required, and the door lock device 10 is easily mounted. Here, the unlocking operation of the door auto-lock device 10 according to the present embodiment will be described based on the flowchart shown in FIG.
図 3、 図 4に示すように、 口ックァ一厶 3 6が掛け金 3 0に掛合した 施錠状態で、 外側 （又は内側） からドア 2 1を開けようとすると、 掛け 金 3 0は口ックアーム 3 6の摺動部 3 8の長さだけしか移動できないの で、 ドア 2 1は半開状態までしか開かない （ステップ 1 ) 。  As shown in FIGS. 3 and 4, when the lock 36 is engaged with the latch 30 and the door 21 is opened from the outside (or the inside) in a locked state, the latch 30 becomes the latch arm 3. Since only the length of the sliding portion 38 of 6 can be moved, the door 21 is opened only to the half-open state (step 1).
この状態で、 ドアセンサー 6 4 ( O N ) によってドア 2 1の開状態を 検知した信号を出力し、 施錠センサー 6 1 ( O N ) は突起部 4 8を検知 した施錠状態を示す信号を出力する （ステップ 2 ) 。  In this state, a signal indicating that the door 21 is open by the door sensor 64 (ON) is output, and the locking sensor 61 (ON) outputs a signal indicating the locking state when the protrusion 48 is detected ( Step 2).
また、 ドアセンサ一 6 4の出力と施錠センサー 6 1の出力を制御装置 5 0に送ることによって半開状態を知らせるブザー 6 5を鳴らす。 ここ で、 ドアの内側に居る人は、 そこから外側の人を確認する事が出来る （ ステップ 3 ) o  In addition, the output of the door sensor 64 and the output of the locking sensor 61 are sent to the control device 50 to sound the buzzer 65 indicating the half-open state. Here, the person inside the door can see the person outside from there (Step 3) o
このとき、 内部の人がドア 2 1の外側の安全な状態を確認できれば、 一旦ドア 2 1を閉める （ステップ 4 ) 。  At this time, if a person inside can confirm the safe state of the outside of the door 21, close the door 21 once (step 4).
ドア 2 1の内側からはキー入力手段 6 6のスィツチキー 6 6 1から 0 F F信号を、 又は、 ドアの外側からはカウン卜キー 6 6 2によって暗証 番号を入力することにより、 解錠指令信号を制御装置 5 0に送る （ステ ップ 5 ) 。  An unlock command signal is input from the inside of the door 21 by inputting a 0FF signal from the switch key 66 1 of the key input means 66 or from the outside of the door by inputting a password using the count key 66 2. Send to the controller 50 (Step 5).
ドアセンサー 6 4はドア 2 1を閉じることよってドア 2 1の閉状態 （ O F F ) を検知した信号を出力する （ステップ 6 ) 。  The door sensor 64 outputs a signal indicating that the door 21 has been closed (OFF) by closing the door 21 (step 6).
ドア 2 1の閉状態の信号を受けて制御装置 5 0はブザー 6 5を停止さ せる （ステップ 7 ) 。  Upon receiving the signal indicating that the door 21 is closed, the control device 50 stops the buzzer 65 (step 7).
ドア 2 1の閉状態を検知した信号と解錠指令信号により、 制御装置 5 0はロックアーム 3 6を解錠状態にする信号をロックァーム駆動機構 4 0に送り、 一方向回転モー夕 4 2を駆動する （ステップ 8 ) 。 The control device 50 sends a signal for unlocking the lock arm 36 to the lock arm drive mechanism 4 based on the signal that detects the closed state of the door 21 and the unlock command signal. Send to 0 and drive one-way rotation motor 42 (step 8).
図 5に示すように、 一方向回転モー夕 4 2により口ックアーム 3 6が ドア 2 1の面と平行になる方向に傾動されて解錠状態になり、 回転板 4 4がほぼ 1 8 0 ° 回耘し、 解錠センサー 6 2が回転板 4 4に設けた突起 部 4 8を検知して、 解錠状態になった検知信号が制御装置 5 0に送られ る （ステップ 9) 。  As shown in FIG. 5, the lock arm 36 is tilted by the one-way rotating motor 42 in a direction parallel to the surface of the door 21 to be unlocked, and the rotating plate 44 is almost 180 °. The tiller is unlocked, and the unlock sensor 62 detects the protrusion 48 provided on the rotating plate 44, and the unlocked detection signal is sent to the controller 50 (step 9).
一方向回転モータ 4 2は、 ロックアーム 3 6が解錠状態になった検知 信号を受けた制御装置 5 0によって停止され、 ドア 2 1を開く ことが可 能となる （ステップ 1 0) 。  The one-way rotation motor 42 is stopped by the control device 50 that has received the detection signal that the lock arm 36 has been unlocked, and the door 21 can be opened (step 10).
解錠状態で一定時間が経過しても ドア 2 1が開状態に操作されないと きは、 ドアセンサ一 6 4の閉状態 （OF F) と制御装置 5 0内のタイマ 一によつて、 ロックアーム駆動機構 4 0が動作し、 ロックアーム 3 6を 自動的に施錠状態にする （ステップ 1 1 ) 。  If the door 21 is not operated in the open state after a certain period of time in the unlocked state, the lock arm is activated by the closed state (OF F) of the door sensor 16 and the timer in the controller 50. The drive mechanism 40 operates to automatically lock the lock arm 36 (step 11).
なお、 前記実施例の解錠動作の順序 （図 2に示すフローチャート参照 ) では、 ドア 2 1の内側から外側の人を確認した （ステップ 3) 後、 安 全な状態であれば、 一旦ドア 2 1を閉める （ステップ 4) ようにしてい るが、 ドア 2 1の内側から外側の人を確認した （ステップ 3) 後、 安全 な状態であれば、 ドア 2 1の内側からはキー入力手段 6 6のスィッチキ - 6 6 1から OFF信号を、 又は、 ドア 2 1の外側からはカウントキ一 6 6 2によって暗証番号を入力することにより、 解錠指令信号を制御装 置 5 0に送り （ステップ 5) 、 次に ドアセンサ一 6 4によってドア 2 1の閉状態 （OFF) を検知した信号を出力し （ステップ 6) 、 その後 ドアを一旦閉める （ステップ 4) ようにして、 ドア 2 1の閉状態を検知 した信号と解錠指合信号により （ステップ 8) 、 ロックアーム 3 6を解 錠状態 （ステップ 9) にしてもよい。 また、 図 4、 図 5において、 施錠センサ一 6 1、 解錠センサ一 6 2は 、 便宜上回転板 4 4に設けた突起部 4 8がほぼ 1 8 0 ° 回転した位置に 配置した状態を示しているが、 ロックアーム 3 6、 連結バー 4 7、 クラ ンクピン 4 5の位置によってロックアーム 3 6の施錠 .解绽状態の位置 は変わるので、 施錠センサー 6 1、 解錠センサー 6 2は取付け位置を変 えられるようにしている。 In the unlocking operation sequence of the above embodiment (see the flowchart shown in FIG. 2), after confirming a person from the inside to the outside of the door 21 (step 3), if it is in a safe state, the door 2 is temporarily stopped. 1 is closed (Step 4), but after confirming the outside person from inside the door 21 (Step 3), if it is safe, the key input means from inside the door 21 6 6 6 Switch key-Send an unlock signal from the control device 50 by inputting an OFF signal from 66 1 or a password from the outside of the door 21 with a count key 66 2 (Step 5). Then, a signal indicating that the door 21 is closed (OFF) is output by the door sensor 164 (step 6), and then the door is closed (step 4) to detect the closed state of the door 21. In response to the unlocked signal and the unlock signal (step 8), Kuamu 3 6 may be unlocked (step 9). 4 and 5, the locking sensor 61 and the unlocking sensor 62 indicate a state in which the projection 48 provided on the rotating plate 44 is located at a position rotated by approximately 180 ° for convenience. However, the lock arm 36 is locked depending on the position of the lock arm 36, the connecting bar 47, and the crank pin 45.Since the unlocked position changes, the lock sensor 61 and unlock sensor 62 are installed at the mounting position. Can be changed.
次に、 図 6に示すフローチヤ一卜に基づき、 ドア 2 1を閉じたときの 施錠動作について説明する。  Next, the locking operation when the door 21 is closed will be described based on the flowchart shown in FIG.
先ず、 ドア 2 1を閉じる （ステップ 1 ) 。 このとき、 ドアセンサ一 6 4は O F Fとなり、 ドア 2 1が開いた状態から閉状態になったことを検 知した信号が制御装置 5 0に送られる （ステップ 2 ) 。  First, the door 21 is closed (step 1). At this time, the door sensor 64 becomes OFF, and a signal that detects that the door 21 has changed from the open state to the closed state is sent to the control device 50 (step 2).
ドアセンサ一 6 4から閉状態になったことを検知した信号が制御装置 5 0に送られると、 制御装置 5 0は口ックアーム駆動機構 4 0にロック アーム 3 6を施錠状態にする信号を送り、 一方向回転モータ 4 2が驟動 される （ステップ 3 ) 。  When a signal indicating that the door sensor is closed is sent from the door sensor to the controller 50, the controller 50 sends a signal to the lock arm drive mechanism 40 to lock the lock arm 36, The one-way rotating motor 42 is driven (step 3).
一方向回転モー夕 4 2によりロックアーム 3 6が傾動して、 回転板 4 4に設けた突起部 4 8が解錠センサ一 6 2に対応した位置から施錠セン サ一 6 1に対応した位置に移動し、 施錠センサー 6 1の出力信号が制御 装置 5 0に出力される （ステップ 4 ) 。  The lock arm 36 is tilted by the one-way rotation motor 42, and the protrusion 48 provided on the rotating plate 44 moves from the position corresponding to the unlock sensor 62 to the position corresponding to the locking sensor 61. And the output signal of the locking sensor 61 is output to the control device 50 (step 4).
施錠センサー 6 1の出力信号が出力されて制御装置 5 0によって口ッ クアーム 3 6が施錠状態になったことが確認されると、 制御装置 5 0は 指合により一方向回転モータ 4 2を停止し、 自動的にロックアーム 3 6 を施錠状態に維持する （ステップ 5 ) 。  When the output signal of the lock sensor 61 is output and the control device 50 confirms that the lock arm 36 is in the locked state, the control device 50 stops the one-way rotating motor 42 by fingering. Then, the lock arm 36 is automatically maintained in the locked state (step 5).
なお、 内部に居た人が外出する場合、 ドア 2 1を閉めると （ステップ 3により） 自動的にロックアーム 3 6が施錠伏態になる。 外出した人が 帰宅した場合は、 ドア 2 1を半開状態にしてドア 2 1の内側に手を入れ 、 キー入力手段 6 6から暗証番号を入力してドア 2 1を一旦閉じ、 解錠 指合信号を制御装置 5 0に送ってロックアーム 3 6を解錠状態にするこ とにより、 ドア 2 1を開くことが可能になる。 If a person inside is going out, closing the door 21 automatically locks the lock arm 36 (step 3). Who went out When returning home, put the door 21 in the half-open state, put your hand inside the door 21, enter the password through the key input means 66, close the door 21 once, and unlock the control signal. The door 21 can be opened by sending it to 50 and unlocking the lock arm 36.
また、 ドアのオートロック装置 1 0を使用しない場合は、 あらかじめ 設定した特殊番号をキー入力して連続解錠状態に維持する。  When the door auto-locking device 10 is not used, a special number set in advance is entered by a key to keep the door unlocked continuously.
図 7に示すように、 本発明の第 2の実施例に係るドアのォートロッタ 装置 1 1は、 減速機 4 1 0を内蔵した可逆回転モータ 4 2 0と、 ブラケ ット 3 4 0に軸支した回動ピン 3 5 0と、 回動ピン 3 5 0に端部を固定 して掛け金 3 0に掛合し得るロックアーム 3 6 0とを有し、 第 1の実施 例に係るドアのォ一トロック装置 1 0の口ックァ一厶駆動機構 4 0の代 わりに、 回動ピン 3 5 0に可逆回転モータ 4 2 0の出力軸 4 3 0を直結 したロックアーム駆動機構 4 0 0を用いた。 それに伴い、 出力軸 4 3 0 に突起部 4 8 0を設け、 ロックアーム 3 6 0がそれぞれ施錠状態及び解 錠状態の位置で施錠センサー 6 1 a及び解錠センサー 6 2 aが突起部 4 8 0を検知するようにしている。 そして、 可逆回転モ一夕 4 2 0を制御 する制御装置 5 0 0は施錠センサー 6 1 a及び解錠センサ一 6 2 aの出 力信号により可逆回転モータ 4 2 0の極性が反転して逆回転する極性反 転機構を備えている。 その他の構成要素は第 1の実施例に係るドアのォ —トロック装置 1 0と同じであるので、 図 1で説明した同一符号を用い て説明する。  As shown in FIG. 7, a door autorotter device 11 according to a second embodiment of the present invention includes a reversible rotating motor 420 incorporating a speed reducer 410 and a bracket 340 supported by a bracket. A lock pin 360 according to the first embodiment, comprising a pivot pin 350 that has been fixed, and a lock arm 360 that can be engaged with a latch 30 with an end fixed to the pivot pin 350. Instead of the mouthpiece drive mechanism 40 of the lock device 10, a lock arm drive mechanism 400 in which the output shaft 430 of the reversible rotary motor 420 is directly connected to the rotation pin 350 is used. Along with this, a projection 480 is provided on the output shaft 430, and the lock sensor 361a and the unlock sensor 622a are provided with the projection 480 when the lock arm 360 is in the locked state and the unlocked state, respectively. 0 is detected. Then, the control device 500 that controls the reversible rotating motor 420 is reversed by reversing the polarity of the reversible rotating motor 420 by the output signals of the lock sensor 61 a and the unlock sensor 62 a. It has a rotating polarity reversing mechanism. Other components are the same as those of the door auto-lock device 10 according to the first embodiment, and therefore, will be described using the same reference numerals described in FIG.
この場合、 ドアのオートロック装置 1 1の動作は第 1の実施例に係る オートロック装置 1 0の場合とほぼ同じである （図 2のフローチャート 参照） 、 口ックアーム駆動機構 4 0 0が停止されてドア 2 1を開くこ とが可能となった後、 制御装置 5 0 0の極性反転機構により可逆回転モ 一夕 4 2 0が逆転可能な状態にセッ 卜され、 ドア 2 1が閉じられるとき に可逆回転モータ 4 2 0が逆転する状態で待機する。 In this case, the operation of the door auto-locking device 11 is almost the same as that of the auto-locking device 10 according to the first embodiment (see the flowchart of FIG. 2). After the door 21 can be opened, the reversible rotation motor is activated by the polarity reversal mechanism of the controller 500. One night 420 is set to a state where it can be reversed, and when the door 21 is closed, it stands by in a state where the reversible rotation motor 420 is reversed.
ドア 2 1を閉じたときには、 ドアセンサ一 6 4の閉状態を検知した信 号が制御装置 5 0 0に送られ、 可逆回転モータ 4 2 0は解錠状態にする ときとは逆方向に駆動され、 突起部 4 8 0が解錠センサー 6 2に対応し た位置から施錠センサー 6 1 aに対応した位置に移動し、 施錠センサー 6 1 aの出力信号が制御装置 5 0 0に出力されて、 可逆回転モータ 4 2 0が回転し、 自動的にロックァ一厶 3 6 0を施錠状態にすることができ る。 このとき、 可逆回転モータ 4 2 0が逆転可能な状態にセッ トされ、 次にロックアーム 3 6 0を解錠状態にしてドア 2 1を開こうとするとき に、 可逆回転モータ 4 2 0が逆転する状態で待機するので、 解錠状態に するときの動作が迅速に切り換えられる。  When the door 21 is closed, a signal that detects the closed state of the door sensor 164 is sent to the control device 500, and the reversible rotary motor 420 is driven in the opposite direction to the unlocked state. The protrusion 480 moves from the position corresponding to the unlocking sensor 62 to the position corresponding to the locking sensor 61a, and the output signal of the locking sensor 61a is output to the control device 500, The reversible rotation motor 420 rotates, and the lock 360 can be automatically locked. At this time, the reversible rotary motor 420 is set in a state in which the reversible rotary motor 420 can be rotated in the reverse direction. Then, when the lock arm 360 is unlocked and the door 21 is to be opened, the reversible rotary motor 420 is set. Since the robot waits in the reverse state, the operation for unlocking can be quickly switched.

In accordance with the distance between the lock sensor 61 0 and the unlock sensor 62 0 that detect retraction, that is, the lock state and the unlock state, respectively, and the magnet 63 0 provided in the door frame 20, for example. A door sensor 640 for detecting the open / closed state of the door 21 is provided. In addition, the door 21 is provided with a buzzer 6500 for notifying that the sliding arm 85 is locked and the door 21 is half open according to the outputs of the lock sensor 6100 and the door sensor 6400. It is provided. Further, a key input means 660 provided with a switch key 661 for locking and unlocking the sliding arm 85 on the inside of the door 21 and a count key 662 for inputting a password can be provided. I have. The key input means 660 sets, for example, a four-digit password, and inputs the password (or the ON-OFF signal of the switch key 661) to unlock the sliding arm 85. Can be entered.
ロック機構部 9 0の近傍には制御装置 5 1 0を設け、 ドア 2 1の開閉 動作に応じてブザー 6 5 0の動作を制御するようにしている。 また、 制 御装置 5 1 0はキー入力手段 6 6 0からの解錠指令信号を受け、 しかも 、 ドアセンサー 6 4 0がドア 2 1の閉状態を検知した信号を確認すると 、 摺動アーム 8 5を解錠状態にする信号をロック機構部 9 0に送り、 一 方向回転モ一夕 9 1を駆動するようにしている。 また、 制御装置 5 1 0 は、 摺動アーム 8 5を摺動して解錠状態にし、 ドア 2 1が開いた状態か ら閉じた場合に作動するドアセンサ一 6 4 0の信号を確認すると、 ロッ ク機構部 9 0に施錠状態にする信号を送り、 一方向回転モータ 9 1を駆 動することによって摺動アーム 8 5を施錠状態にするようにしている。 なお、 摺動アーム 8 5の下方にはチヱーン 8 0の振れが大きくならない ように振れ止め 8 9を設けている。  A control device 5100 is provided near the lock mechanism 90 to control the operation of the buzzer 6500 according to the opening / closing operation of the door 21.

Further, when the control device 5100 slides the sliding arm 85 to the unlocked state and confirms the signal of the door sensor 1640 that operates when the door 21 is closed from the open state, A signal for locking is sent to the lock mechanism 90, and the one-way rotating motor 91 is driven to lock the sliding arm 85. In addition, a swing stopper 89 is provided below the sliding arm 85 so that the swing of the chain 80 does not increase.
ここで本実施例に係るドアのォ一トロック装置 1 3の動作について説 明する。 なお、 動作のステップは第 1の実施例に係るドアのォ一トロッ ク装置 1 0の場合とほぼ同じである （なお、 動作ステップは図 2に示す フローチヤ一トを参考にすることができる） 。 Here, the operation of the door lock device 13 according to the present embodiment will be described. I will tell. The operation steps are almost the same as those in the case of the door lock apparatus 10 according to the first embodiment (the operation steps can be referred to the flowchart shown in FIG. 2). .
図 1 0 ( A ) に示すように、 掛け金 8 2が摺動アーム 8 5に掛合しう る施錠伏態で、 外側 （又は内側） からドア 2 1を開けようとすると、 掛 け金 8 2はチ ーン 8 0に垂直に下げられた位置から掛け金 8 2が摺動 アーム 8 5に掛合する位置に引き上げられるまでの長さだけしか移動で きないので、 図 1 0 ( B ) に示すように、 ドア 2 1は半開伏態までしか 開かない。 この状態で、 ドアセンサー 6 4 0によってドア 2 1の開状態 を検知した信号と施錠センサー 6 1 0が突起部 9 6を検知した出力信号 によって半開状態を知らせるブザー 6 5 0が鳴る。 ここで、 ドア 2 1の 内側に居る人は、 そこから外側の人を確認することが出来る。  As shown in FIG. 10 (A), when the latch 21 is locked and the sliding arm 85 is locked, and the door 21 is opened from the outside (or inside), the latch 8 2 Can move only the length from the position lowered vertically to the chain 80 to the position where the latch 82 is engaged with the sliding arm 85, so that it is shown in Fig. 10 (B). Thus, the door 21 can only be opened to a half-yield state. In this state, the buzzer 650 that notifies the half-open state is sounded by the signal that the door sensor 640 detects the open state of the door 21 and the output signal that the lock sensor 610 detects the protrusion 96. Here, the person inside the door 21 can see the person outside from there.
このとき、 安全な状態であれば、 キー入力手段 6 6 0から暗証番号 （ 又は O N— O F F信号） を入力することにより、 ブザー 6 5 0を停止さ せ、 解錠指令信号を制御装置 5 1 0に送る。 一旦外部の人に、 あるいは 内部の人によってドア 2 1を閉じると、 ドアセンサー 6 4 0はドア 2 1 の閉状態を検知した信号を出力し、 制御装置 5 1 0に送る。 ドア 2 1の 閉状態を検知した信号と解錠指令信号を受けて、 制御装置 5 1 0はロッ ク機構部 9 0に解錠状態にする信号を送り、 一方向回転モータ 9 1を駆 動する。 そうすると、 図 1 0 ( C ) に示すように、 摺動アーム 8 5が解 錠状態になり、 解錠センサー 6 2 0は回転板 9 4 'に設けた突起部 9 6を 検知して検知信号が制御装置 5 1 0に送られる。 そこで、 解錠状態にな ると、 一方向回転モータ 9 1が停止され、 ドア 2 1を開くことが可能と る。  At this time, if it is in a safe state, the buzzer 650 is stopped by inputting a password (or ON-OFF signal) from the key input means 660, and the unlock command signal is sent to the control unit 51. Send to 0. Once the door 21 is closed by an outside person or by an inside person, the door sensor 640 outputs a signal indicating that the door 21 is closed and sends the signal to the control unit 5 10. Upon receiving the signal indicating that the door 21 has been closed and the unlock command signal, the controller 510 sends a signal for unlocking the lock mechanism 90 to drive the one-way rotating motor 91. I do. Then, as shown in FIG. 10 (C), the sliding arm 85 is unlocked, and the unlocking sensor 62 detects the protrusion 96 provided on the rotating plate 94 ′ and detects the detection signal. Is sent to the control device 5 10. Therefore, when the door is unlocked, the one-way rotating motor 91 is stopped, and the door 21 can be opened.
次に、 ドア 2 1を閉じたときには、 ドアセンサ一 6 4 0が開いた伏態 から閉状態になったことを検知した信号が制御装置 5 1 0に送られ、 制 御装置 5 1 0からロック機構部 9 0に摺動アーム 8 5を施錠状態にする 信号を送り、 一方向回転モー夕 9 Iを駆動すると、 回転板 9 4に設けた 突起部 9 6が解錠センサー 6 2 0に対応した位置から施绽センサー 6 1 0に対応する位置に移動する。 ここで、 施錠センサー 6 1 0の出力信号 が制御装置 5 1 0に出力されて、 図 1 0 ( A ) に示すように、 一方向回 転モータ 9 1を停止し、 自動的に摺動アーム 8 5を施錠状態に維持する ことができる。 Next, when the door 21 is closed, the door sensor 640 is opened and A signal that detects that the sliding arm 85 has been closed is sent to the control device 5 10, and a signal to lock the sliding arm 85 is sent from the control device 5 10 to the lock mechanism 90, and the one-way signal is sent. When the rotating motor 9I is driven, the protrusion 96 provided on the rotating plate 94 moves from a position corresponding to the unlocking sensor 62 to a position corresponding to the application sensor 61. Here, the output signal of the locking sensor 6 10 is output to the control device 5 10, and the one-way rotation motor 9 1 is stopped as shown in FIG. 85 can be kept locked.
なお、 内部の人が外出する場合、 ドア 2 1を閉めると自動的に摺動ァ —厶 8 5が施錠状態になるが、 帰宅時に半開状態にしてドア 2 1の内側 に手を入れ、 キー入力手段 6 6 0から暗証番号 （又は O N— O F F信号 ) を入力して解錠指令信号を制御装置 5 1 0に送って摺動アーム 8 5を 解錠状態にすることにより、 ドア 2 1を開くことが可能になる。  When a person inside the house goes out, the sliding arm 85 is automatically locked when the door 21 is closed. By inputting a password (or ON-OFF signal) from the input means 660 and sending an unlock command signal to the control device 510 to put the sliding arm 805 in the unlocked state, the door 21 is opened. It becomes possible to open.
また、 図 9に示すように、 掛け金 8 2に例えば所定の番号を設定する ことにより、 解錠できる番号鍵 8 8を設けておき、 チェーン 8 0から掛 け金 8 2を分解可能とすることができる。  In addition, as shown in FIG. 9, a number key 88 that can be unlocked is provided by setting a predetermined number to the latch 82, for example, so that the latch 82 can be disassembled from the chain 80. Can be.
この場合、 非常時にキー入力手段 6 6 0の暗証番号を知らない、 例え ばビルやマンションの管理人などの特定の人に番号鍵 8 8の操作を教え ておき、 特定の人が半開状態のドア 2 1の隙間から番号鍵 8 8を操作し てチェーン 8 0から掛け金 8 2を外し、 ドア 2 1を自由に開閉可能にす ることが出来る。 なお番号鍵 8 8の代わりに南京錠を使用することも可 能である。  In this case, in case of an emergency, the user does not know the password of the key input means 660, for example, teaches the operation of the number key 88 to a specific person, such as a building or condominium manager, so that the specific person is half open. By operating the number key 88 from the gap of the door 21, the latch 82 is removed from the chain 80, and the door 21 can be freely opened and closed. It is also possible to use a padlock instead of the number key 88.
また、 この場合、 ロック機構部 9 0は逆転防止機能を有する減速機構 9 3を用いて摺動アーム 8 5を駆動しているので、 ドア 2 1を半開きの 状態にしてチェーン 8 0ゃ摺動アーム 8 5を握んで、 強制的に摺動ァ一 厶 8 5を摺動しょうとしても摺動させることが出来ず、 極めて安全であ なお、 第 4の実施例に係るドアのオートロック装置では、 ロック機構 部に一方向回転モー夕を使用した例について説明したが、 一方向回転モ 一夕の代わりに第 2の実施例に係るドアのォートロック装置で説明した 可逆回転モ一夕と極性反転機構を用いたものでもよい。 In this case, since the lock mechanism 90 drives the sliding arm 85 by using the speed reduction mechanism 93 having a reverse rotation preventing function, the door 21 is opened halfway and the chain 80 is slid. Hold arm 8 5 and forcibly slide It is extremely safe because it cannot slide even if the user tries to slide the room 85. In the door auto-locking device according to the fourth embodiment, a one-way rotating motor is used for the lock mechanism. However, instead of the one-way rotating motor, the reversible rotating motor and the polarity reversing mechanism described in the door auto-lock device according to the second embodiment may be used.
前記第 4の実施例に係るドアのォ一卜ロック装置の説明で、 図 9に施 錠センサーと解錠センサーの位置を回転板に設けた突起部がほぼ 1 8 0 ° 回転した位置に設けた例について説明したが、 摺動アームの移動する 長さによって、 施錠センサーと解錠センサ一の位置を変更し、 摺動ァ一 ムの施錠状態及び解錠状態を正確に実現するようにしてもよい。  In the description of the door auto-lock device according to the fourth embodiment, FIG. 9 shows the positions of the lock sensor and the unlock sensor provided at a position where the projection provided on the rotating plate is rotated by approximately 180 °. The position of the locking sensor and the unlocking sensor was changed according to the length of the sliding arm to move, so that the locked and unlocked state of the sliding arm was accurately realized. Is also good.
また、 前記第 1〜第 4の実施例に係るドアのオートロック装置は開き ドアに適用した例について説明したが、 引き戸に適用することも可能で あ 。  In addition, although the automatic door lock devices according to the first to fourth embodiments have been described as applied to the open doors, they may be applied to sliding doors.
また、 前記第 1〜第 4の実施例に係るドアのォートロック装置におい てキー入力手段に暗証番号を入力する場合、 直接手で入力する代わりに 、 赤外線、 無線等を用いて入力するようにすることも可能である。 また 、 キー入力手段のカウントキーは 4桁に限るものではなく、 3桁以下又 は 5桁以上でもよい。  In the door lock device according to the first to fourth embodiments, when inputting a password into the key input means, instead of directly inputting the password by hand, the input is performed using infrared rays, wireless communication, or the like. It is also possible. Further, the count key of the key input means is not limited to four digits, but may be three digits or less or five digits or more.
〔産業上の利用可能性〕 [Industrial applicability]
第 1の発明のドアのォートロック装置においては、 口ックアームの施 錠状態及び解錠状態をそれぞれ検出する施錠センサー及び解錠センサー と、 ドアの開閉状態を検出するドアセンサーと、 ロックアームが施錠状 態でかつドアが半開状態であることを知らせるブザーと、 ドアの内側に 設けてロックアームの解錠指令を入力するキー入力手段とを備え、 キー 入力手段からの解錠指合とドアセンサーの閉状態の検知信号により口ッ クアームを解錠状態にし、 また、 ドアが開いた状態から閉じた場合に口 ックアームを施錠状態にする制御装置を有するので、 外部の人が施錠状 態で外側 （又は内側） からドアを開けようとすると、 ドアは半開状態ま でしか開かず、 その状態でブザーが鳴り、 内部の人はドアの外側の人を 確認する事が出来る。 安全な状態であれば、 内側からはキー入力手段の スィツチキーで、 外側からはキー入力手段のカウントキ一で O N—〇F F信号や暗証番号などの所定の解錠を指合する信号を制御装置に送り、 一旦外部の人に、 あるいは内部の人によってドアを閉じることで、 ドア センサーからドアの閉状態を検知した信号を制御装置に送り、 制御装置 は口ックアーム駆動機構により口ックァ一厶を解錠状態にする。 この状 態で外部の人はドアを開くことが可能となる。 また、 ドアを閉じたとき にはドアセンサーの信号が制御装置に送られ、 自動的に口ックアームを 施錠状態にすることができる。 In the door auto-lock device of the first invention, a lock sensor and an unlock sensor for respectively detecting a locked state and an unlocked state of the lock arm, a door sensor for detecting an open / closed state of the door, and a lock arm for the lock state Buzzer that indicates that the door is half open And key input means for inputting an unlock command for the lock arm. The unlock arm is unlocked by an unlock instruction from the key input means and a detection signal of the closed state of the door sensor. With a control device that locks the lock arm when it is closed from the open state, if an outsider tries to open the door from the outside (or inside) in the locked state, the door will only open up to the half-open state. Instead, the buzzer sounds in that state, and people inside can see people outside the door. If it is safe, use the switch key of the key input means from the inside, and use the count key of the key input means from the outside. Once the door is closed by an outside person or by an inside person, the door sensor sends a signal indicating that the door has been closed to the controller, and the controller unlocks the door by the door arm drive mechanism. Change to the locked state. In this state, the outside person can open the door. When the door is closed, the signal of the door sensor is sent to the control device, and the lock arm can be automatically locked.
したがって、 口ックァ一厶ゃチヱーンを操作するのを忘れることがあ つても自動的に施錠状態にすることができ、 特に、 子供や身体が不自由 な老人 ·身障者がドアロック装置を操作する必要がなく、 容易にかつ確 実に安全が確保できる。  Therefore, even if the user forgets to operate the mouthpiece chain, the door can be automatically locked, especially if the child or the elderly or handicapped has to operate the door lock device. And safety can be easily and reliably secured.
また、 ドアのオートロック装置は、 その構成要素を全てドアの内側に ドアの外観を損することなく取付け、 ドアの外側からはドアのォート口 ック装置の存在が直ちに知れることがないので、 室内の安全を確保する ことができる。  In addition, the door auto-lock device is installed inside the door without damaging the appearance of the door, and the door lock device is not immediately visible from the outside of the door. Safety can be ensured.
特に、 第 1の発明のドアのオートロック装置においては、 ロックァー ム駆動機構は一方向回転モータと、 一方向回転モ一夕の出力軸に固定さ れた回転板と、 回転板に偏心して設けたクランクピンと、 ロックアーム の中間部に設けた連結ピンと、 連結ピンとクランクピンとにそれぞれ両 端部が回動自在に連結された連結バーとを備えているので、 回転板が一 方向に半回転する毎に、 口ックアームの施錠状態と解錠状態とを交互に 実現することが出来る。 したがって、 制御装置は、 一方向回転モー夕を 一方向にのみ回転駆動する構成でよいので、 制御装置を簡単で安価にす ることが可能である。 In particular, in the door auto-lock device of the first invention, the lock-arm driving mechanism is fixed to the one-way rotating motor and the output shaft of the one-way rotating motor. A rotating plate, a crank pin provided eccentrically to the rotating plate, a connecting pin provided at an intermediate portion of the lock arm, and a connecting bar having both ends rotatably connected to the connecting pin and the crank pin, respectively. Therefore, each time the rotating plate makes a half turn in one direction, the locked state and the unlocked state of the mouthpiece can be realized alternately. Therefore, the control device may be configured to rotate the one-way rotating motor only in one direction, so that the control device can be made simple and inexpensive.
また、 第 1の発明のドアのオートロック装置においては、 ロックァー 厶駆動機構は可逆回転モー夕と、 ロックアームの端部に固定した回動ピ ンとを備え、 回動ピンと可逆回転モータの出力軸とを直結しているので 、 πックアームを直接可逆回転モータの出力軸に結合した極めて簡単な 構成の口ックアーム駆動機構にすることができ、 ドアのォートロック装 置の機械的構成を簡単で安価にすることが出来る。  In the door auto-lock device of the first invention, the lock arm driving mechanism includes a reversible rotation motor and a rotation pin fixed to an end of the lock arm, and outputs the rotation pin and the output of the reversible rotation motor.
