【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、自動ドアの錠を解除するための解錠装置に関
する。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an unlocking device for unlocking an automatic door.
店舗や金庫等に用いられる自動ドアでは、安全のために
ドアを閉じた状態では施錠するようになっており、ドア
を開くときにはその度に錠が解除される。An automatic door used in a store, a safe, or the like is designed to be locked when the door is closed for safety, and is unlocked each time the door is opened.
第３図はこのような施錠状態を示したもので、ドアＡに
取り付けられた係止板Ｂ（被係合部材）の係合孔ｂに、
枠壁等に取り付けられている電気錠Ｄの係止棒ｄ（係合
部材）を挿通して、ドアＡが開かないようにしている。FIG. 3 shows such a locked state, in which the engagement hole b of the locking plate B (engaged member) attached to the door A is
The lock bar d (engagement member) of the electric lock D attached to the frame wall or the like is inserted to prevent the door A from opening.
電気錠Ｄに通電すると、係止棒ｄが電磁力により係合孔
ｂから引き抜かれるので、ドアＡを開けることが出来る
ようになる。When the electric lock D is energized, the locking rod d is pulled out from the engagement hole b by the electromagnetic force, so that the door A can be opened.
〔考案が解決しようとする問題点〕 第３図に示すような施錠状態でドアＡを無理に開けよう
とすると、第４図に示すように係合孔ｂと係止棒ｄのク

具備したことを構成上の特徴とするものである。The automatic door unlocking device of the present invention locks the door by loosely fitting the engaging member to the engaged member in a state where the door is closed with respect to the frame wall and the like, and drives the actuator to lock the door. In an unlocking device for an automatic door that unlocks a lock by electromagnetically moving the engaging member when opening, when opening the door in the locked state, prior to the opening operation. Monitoring means for monitoring whether or not the engaging member is disengaged from the engaged member within a predetermined time period, and confirmation of disengagement of the engaging member from the engaged member within a predetermined time period by the monitoring means. If not, a closing operation control means is provided to reversely drive the actuator to close the door.
本考案の自動ドアの解錠装置では、解錠の際に被係合部
材から係合部材が離脱されない時、一時的にドアを閉動
作させることが出来る。The automatic door unlocking device of the present invention can temporarily close the door when the engaging member is not disengaged from the engaged member during unlocking.

お、図に示す実施例により本考案が限定されるものでは
ない。Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings. Here, FIG. 1 is a conceptual diagram of the structure of an automatic door including an unlocking device according to an embodiment of the present invention, FIG. 2 is a flowchart of the operation of the unlocking device according to the present invention, and FIG. FIG. 6 is a front view showing a configuration example, and FIG. 6 is a side view of the same. The present invention is not limited to the embodiments shown in the drawings.
第１図に示す自動ドア１は、人検知センサ５で通行人を
検知すると、モータ４（アクチュエータ）およびベルト
３を駆動して、ドア２を開け、人が検知されなくなる
と、モータ４及びベルト３を反転してドア２を閉じるも
のである。かかる制御は、制御開路６により行われる。The automatic door 1 shown in FIG. 1 drives the motor 4 (actuator) and the belt 3 when the person detection sensor 5 detects a passerby, opens the door 2, and when the person is no longer detected, the motor 4 and the belt 3. 3 is inverted and the door 2 is closed. Such control is performed by the control circuit 6.
ドア２を閉じた状態では、ドア２に取り付けられた係止
板７（被係合部材）の係合孔7aに、枠壁等に取り付けら
れた電気錠９の係止棒８（係合部材）が挿入（遊嵌）さ
れ、ドア２が開かないように施錠されている。In the state where the door 2 is closed, the locking plate 7 (engaged member) attached to the door 2 is fitted into the engaging hole 7a of the electric lock 9 attached to the frame wall or the like (the engaging member 8). ) Is inserted (played loosely) and locked so that the door 2 cannot be opened.
ドア２を開く時は、制御開路６が電気錠９に通電し、電
磁力により係止棒８を係合孔7aから引き抜いて、錠を解
除する。When the door 2 is opened, the control opening 6 energizes the electric lock 9, and the locking rod 8 is pulled out from the engagement hole 7a by the electromagnetic force to release the lock.
係止棒８が抜かれた否かはリミットスイッチ10によりチ
ェックされる。The limit switch 10 checks whether or not the locking rod 8 is pulled out.
制御回路６は、マイクロコンピュータを中枢とするもの
で、ドア２を開くときは解錠装置として機能する。第２
図はその解錠装置としての作動を示したものである。The control circuit 6 has a microcomputer as a center, and functions as an unlocking device when the door 2 is opened. Second
The figure shows the operation of the unlocking device.
すなわち、人検知センサ５で通行人が検知されると（S
1）、電気錠９を解除するように信号を出力する（S
2）。That is, when a passerby is detected by the human detection sensor 5 (S
1) Output a signal to release the electric lock 9 (S
2).
これにより電気錠９は、係止棒８を引き抜くように電磁
力を発生させる。As a result, the electric lock 9 generates an electromagnetic force so as to pull out the locking rod 8.
制御回路６は、係止棒８が引き抜かれたか否かをリミッ
トスイッチ10によりチェックし（S3）、引き抜かれてお
れば「ドア開処理」へ移行する。The control circuit 6 checks with the limit switch 10 whether the locking rod 8 has been pulled out (S3), and if it has been pulled out, it shifts to the "door opening process".
ところが、所定時間（例えば0.2秒）経過しても係止棒
８が引き抜かれたことを確認できないときは（S4）、モ
ータ４及びベルト３を駆動してドア２を閉じ方向に動作
させる（S5）。However, when it is not possible to confirm that the locking rod 8 is pulled out even after a predetermined time (for example, 0.2 seconds) has passed (S4), the motor 4 and the belt 3 are driven to operate the door 2 in the closing direction (S5). ).
この動作ステップ（S3,S4）が施錠状態にある上記ドア
２を開動作させる際、その開動作に先立って所定時間内

監視する監視手段に相当し、動作ステップ（S5）が上記
監視手段により所定時間内に上記係止板７からの上記係
止棒８の離脱が確認されなかった時、上記モータ４を反
転駆動して上記ドア２を閉動作させる閉動作制御手段に
相当する。In this operation step (S3, S4), when the door 2 in the locked state is opened, it is determined whether or not the locking rod 8 is disengaged from the locking plate 7 within a predetermined time prior to the opening operation. Corresponding to monitoring means for monitoring, in the operation step (S5), when the monitoring means does not confirm that the locking rod 8 is detached from the locking plate 7 within a predetermined time, the motor 4 is driven in reverse. And corresponds to a closing operation control means for closing the door 2.
そして、再び係止棒８が引き抜かれたか否かをリミット
スイッチ10でチェックし（S6）、引き抜かれていれば
「ドア開処理」へ移行する。Then, it is checked again with the limit switch 10 whether or not the locking rod 8 has been pulled out (S6), and if it has been pulled out, the "door opening process" is entered.
ところが、例えば15秒経過しても係止棒８が引き抜かれ
たことを確認できないときは（S7）、解錠できないエラ
ーが発生したものと判定し、「エラー処理」へと移行す
る。However, if it cannot be confirmed that the locking rod 8 has been pulled out even after 15 seconds have passed (S7), it is determined that an error that cannot be unlocked has occurred, and the process proceeds to "error processing".
上記作動によれば、ドア２が無理に動かされて係止板７
と係止棒８とが強く当接した状態となり電磁力では係止
棒８を引き抜けない場合でも、ドア２が一時的に閉動作
させられるためクリアランスを回復し、電磁力で係止棒
８を引き抜くことが出来るようになる。従って、他のエ
ラーの原因がない限り確実に解錠を行うことが出来る。According to the above operation, the door 2 is forced to move and the locking plate 7
Even when the locking rod 8 and the locking rod 8 are in strong contact with each other and the locking rod 8 cannot be pulled out by the electromagnetic force, the clearance is restored because the door 2 is temporarily closed, and the locking rod 8 is locked by the electromagnetic force. Can be pulled out. Therefore, the unlocking can be surely performed unless there is another cause of the error.
第５図および第６図は電気錠９の具体的構成例を示した
ものである。FIG. 5 and FIG. 6 show a specific configuration example of the electric lock 9.
係止棒８はＬリンク11の一端に連結され、そのＬリンク
11は戻しバネ12によって係止棒８を下向きに移動させる
ように回転する付勢力を与えられている。The locking rod 8 is connected to one end of the L link 11, and the L link
A return spring 12 applies an urging force to rotate 11 so as to move the locking rod 8 downward.
また、Ｌリンク11の他端はプランジャ13に連結され、そ
のプランジャ13はソレノイド14に吸引されるようなって
いる。The other end of the L link 11 is connected to a plunger 13, and the plunger 13 is attracted by a solenoid 14.
そこで、ソレノイド14に通電しないときは、係止棒８が
下向きに突出して係止板７の係合孔7aに挿入され、施錠
状態となる。Therefore, when the solenoid 14 is not energized, the locking rod 8 projects downward and is inserted into the engaging hole 7a of the locking plate 7 to be locked.
ソレノイド14に通電すると、プランジャ13が吸引される
ため戻しバネ12の付勢力に抗してＬリンク11が回転し、
係止棒８を引き上げる。そこで、錠が解除される。When the solenoid 14 is energized, the plunger 13 is attracted and the L-link 11 rotates against the biasing force of the return spring 12,
Pull up the locking rod 8. Then, the lock is released.
尚、Ｌリンク11から突出する支軸15と作用軸16は、これ
らにレバー（図示省略）を装着して支軸15を中心に作用
軸16を手動で回転できるようにし、Ｌリンク11を動かし
て手動による係止棒８の上下を可能とするものである。A lever (not shown) is attached to the support shaft 15 and the working shaft 16 protruding from the L-link 11 so that the working shaft 16 can be manually rotated about the support shaft 15 to move the L-link 11. It is possible to manually move the locking rod 8 up and down.
