Description

【0001】
【産業上の利用分野】
本発明は、家庭用等の電動シャッタ閉鎖時において、ロック機構とシャッタのリミット機構とを連動させ、シャッタの下限位置決めをする制御装置に関する。
【0002】
【従来の技術】
電動シャッタは、その開閉が機械的に行えるため、非常に重宝され、業務用だけでなく、家庭用にも広く普及している。この電動シャッタの使用目的のひとつとして防犯が挙げられるが、家庭用の電動シャッタはシャッタ自体が比較的軽量であり、しかも通常開放方向にシャッタがバネ等により付勢されているために、手作業で閉鎖したシャッタを持ち上げて開放できるので、従来から、シャッタ閉鎖時にシャッタを施錠するロック機構が設けられる。
【0003】
また、電動シャッタには、シャッタ閉鎖時のロック機構だけでなく、開閉用モータが過度にシャッタを繰り出すことにより、開閉用モータやスラット等の破損防止を図るリミット機構の設置が必要となる。このリミット機構には、開閉用モータの回転数を計測し、シャッタの繰出量を制御する方法が知られている。
【0004】
このほか、リミット機構の例として、実公昭50−6992号「電動シャッタの自動停止装置」がある。これは、シャッタに磁石を取り付け、マイクロリードスイッチがシャッタが下降して近付く磁石による磁界の変化からシャッタが最下端に達したことを察知して、開閉用モータを停止させるものである。
【0005】
【発明が解決しようとする課題】
回転用モータの回転数を計測し、シャッタの繰出量を制御するリミット機構では、適切な作動が難しく、シャッタの大きさが変わればその都度回転数とシャッタの繰出量との関係を調整し直さなければならず、この調整をシャッタ取付現場で行うのは手間が掛かり、作業性を低下させていた。また、「電動シャッターの自動停止装置」では、磁界の変化を正確に察知することが難しく、シャッタの停止を確実に行えなかった。
【0006】
ロック機構とリミット機構とでは目的が異なるが、理想的にはロック機構により確実な施錠がされた状態でリミット機構を作動させてシャッタの繰出しを停止させるのが好ましい。ところが、従来のロック機構とリミット機構とは別体であり、前記のような連動を実現するための調整は難しく、場合によっては施錠されていないのにシャッタが停止してしまうこともあったのである。
【0007】
【課題を解決するための手段】
以上の問題を解決すべく開発したものが、掛止突起をシャッタ側縁に設け、この掛止突起を掛止する施錠部材と、施錠部材と掛合する保持部材と、施錠部材の回動を検知する検知部材とをシャッタレールに設けた開閉制御装置であり、施錠部材はシャッタが最下限に達した際に掛止突起を掛止する掛止部と保持部材と掛合する掛合部とを有し、掛止部が掛止突起を掛止する施錠位置から掛止部が掛止突起を解放する解錠位置へ付勢されて両状態の間において回動自在にしてなり、保持部材は施錠部材へ向けて付勢されて施錠位置において施錠部材の掛合部と掛合させ、シャッタの開閉用モータの起動に連動して施錠部材との前記掛合を解除してなり、検知部材は回動した施錠部材が施錠位置に達したことを検知してシャッタの開閉用モータを停止させるようにする。
【0008】
【作用】
シャッタの下降又は上昇に合わせて、各部の作用を説明する。シャッタ下降時には、施錠部材は付勢によって解錠位置にあり、この施錠部材に向けて付勢した保持部材は施錠部材の掛合部と掛合できず、施錠部材は施錠位置へ向けて自由に回動できる状態にある。シャッタが更に下降すると掛止突起が施錠部材の掛止部に掛かり始め、施錠部材はシャッタの下降に合わせて、掛止突起により施錠位置へ向けて回動させられる。そして、シャッタが最下限に達した段階で施錠部材は施錠位置に至り、保持部材は掛合部と掛合して、施錠部材の回動を規制する。このため、この状態でシャッタを上昇させようとしても、保持部材に回動を規制された施錠部材が掛止突起を掛止するため、施錠位置を保持できる。同時に、検知部材は施錠部材の施錠位置を検知して、シャッタの開閉用モータを停止させる。
【0009】
開閉用モータの起動によりシャッタが上昇を始めようとすると、保持部材が前記開閉用モータの起動に連動して掛合部との掛合を解除するので、施錠部材は再び自由に回動できるようになる。したがって、シャッタの上昇に伴って掛止突起が掛止部から解放され、施錠部材は付勢により解錠位置へ復帰し、シャッタはなんら拘束を受けることなく上昇できるのである。
【0010】
【実施例】
以下、本発明の実施例につき、図を参照しながら説明する。図1は本発明の開閉制御装置を施した電動シャッタの正面図である。図1に見られるように、電動シャッタは、上部に開閉用モータ(図示せず)を内蔵したシャッタボックス1にシャッタ2を格納し、スイッチ(図示せず)の操作で開閉する。開閉制御装置は、掛止突起3をボトムスラット4に突設し、施錠部材5、保持部材6及び検知部材7を一体にしてケース8内に納め(図2以下参照)、このケース8をシャッタレール9下端付近に配して構成する。
【0011】
本発明の開閉制御装置は、シャッタを施錠すると同時に、シャッタの過剰な開閉によって開閉用モータやスラット等が破損しないように、開閉用モータを停止させるリミット機構を併せ有し、両者が連動する点に特徴がある。この点に留意し、開閉制御装置の作動手順について、図を参照しながら説明する。図2から図4はシャッタ2を閉鎖して施錠するまでを、図5から図7はシャッタ2が解錠して開放するまでを順に表した開閉制御装置の断面図である。
【0012】
図2に基づき、開閉制御装置の構造を説明する。掛止突起3は、ボトムスラット4の両側から伸退自在に突出(図2中図面手前側)させている。施錠部材5は、前記掛止突起3に向けて切り欠いた掛止部10を有する円盤状の部材であり、掛止部10が上向きの解錠位置(図2参照)と水平向きの施錠位置(図4参照)との間で回動可能にケース8に設けた回動軸11に軸着され、付勢突起12とケース8とを連結するバネ13により解錠位置へ向けて付勢されている。また、施錠部材5上面には保持部材6を嵌込む溝14を設けてあり、更に本実施例では施錠位置への回動が一定限度で停止するように、ケース8に当接する規制突起15を掛止部13と溝14との間に設けてある。
【0013】
保持部材6は、前記施錠部材5の溝14に嵌め込む嵌合棒16を下端に貫設したプランジャ17を有するソレノイド18からなり、このプランジャ17に遊嵌したコイルバネ19により下方へ向けて付勢されている。この保持部材6は、施錠部材5が解錠位置にある時には嵌合棒16を施錠部材5上面に摺接させ、施錠部材5が施錠位置になった時に溝14へ嵌合棒16を掛合させるが、開閉用モータの起動に連動してソレノイド18を作動するとプランジャ19が上方へ変移し、溝14の位置に拘わりなく、施錠部材5と保持部材6との掛合が解除される。
【0014】
検知部材7は、リミットスイッチ20と押圧突起21とから構成される。押圧突起21は回動軸11に取付け、施錠部材5の回動に従って回動する。押圧突起5の回動に連動すればよいので、施錠部材5と一体に設けてもよい。これにより、施錠部材5が施錠位置に達したときに、ケース8に固着したリミットスイッチ20を回動した押圧突起21が押し、掛止突起3が施錠部材5の掛止部10に掛止されたこと、すなわち施錠位置を検知して、その旨を電気信号として出力リード線22から出力し(図4参照)、開閉用モータを停止させる。この検知部材としては、常態として微弱電流をソレノイドに通電しておき、施錠部材の溝に嵌合棒が掛合して生ずるソレノイドの磁界変化を検知して、施錠の完了を検知するようにしたものでもよい。
【0015】
まず、シャッタを閉鎖して施錠するまでを説明する。図2はシャッタ2が下降している状態(閉鎖手順1)を表している。シャッタ2が下降してきても、掛止突起3が施錠部材5の掛止部10に当接しない限り、施錠部材5は解錠位置で停止している。保持部材6のソレノイド18は、嵌合棒16を施錠部材5上面に当接させた状態にあり、プランジャ17は上方へ押し込められている。また、検知部材7を構成する押圧突起21は下方へ回動してリミットスイッチ20から離れているので、開閉用モータは作動を続け、更にシャッタ2を繰り出してくる。
【0016】
図3は施錠部材5の掛止部10に掛止突起3が掛止し始めた状態(閉鎖手順2)を表している。掛止突起3が掛止部10に当接して下降を続けると、施錠部材5は施錠位置へ向けて(図3中左回転)回動し始める。保持部材6のソレノイド18は、施錠部材5が回動し始めても、施錠位置に至るまでは嵌合棒16を施錠部材5上面に摺接させるだけで、プランジャ17は依然上方に押し込まれたままである。また、検知部材7を構成する押圧突起21は、リミットスイッチ20に近付くものの未だ押圧するには至らないので、開閉用モータは作動を続ける。
【0017】
図4は掛止突起3が完全に掛止部10で掛止され、同時に検知部材7が開閉用モータの停止信号を送出した状態(閉鎖手順3)を表している。掛止突起3が完全に掛止部10に掛止された状態、すなわち施錠位置に至ると、コイルバネ19の付勢によりプランジャ17が下降して嵌合棒16が施錠部材5の溝14と掛合して、保持部材6が施錠部材5を施錠位置に拘束するようになる。また、検知部材7を構成する押圧突起21が、リミットスイッチ20を押し、開閉用モータを停止させる。こうして、本発明の開閉制御装置は、繰り出されたシャッタの施錠と開閉用モータの停止とを同時に実現するのである。
【0018】
続いて、解錠してシャッタを開放するまでを説明する。図5は施錠位置のシャッタ2に対し巻上モータ(図示せず)を起動し、同時にソレノイド18を励磁させた状態(開放手順1)を表している。施錠位置では、シャッタ2だけを持ち上げようとしても、保持部材6に回動を拘束された施錠部材5が掛止突起3を掛止するので、開放することはできない。しかし、巻上モータの起動と同時に入力リード線23へ信号を送り込み(図5参照)、ソレノイド18を励磁することによりプランジャ17を引き上げ、嵌合棒16と溝14との掛合を解除して施錠部材5の拘束を解くことで、シャッタ2の巻上げを可能にするのである。
【0019】
図6は、施錠部材5が解錠位置へ向けて回動している状態(開放手順2)を表している。拘束を解かれた施錠部材5がバネ13の付勢により解錠位置へ向けて回動を始めると、保持部材6の嵌合棒16に対して施錠部材5の溝14の位置がずれるから、この段階でソレノイド18の励磁を解いても、嵌合棒16は施錠部材5上面に摺接するだけで、再び溝14と掛合して施錠部材5の回動を拘束することはない。また、この段階に至れば、検知部材7を構成する押圧突起21はリミットスイッチ20から離れるので、仮にシャッタ2を繰り出す方向にスイッチを切り替れば、シャッタ2は完全に閉鎖するまで下降させることができる。
【0020】
図7は施錠部材5の回動が終わり、完全に解錠位置に復帰した状態(開放手順3)を表している。この段階に至れば、掛止突起3は施錠部材5の掛止部10から完全に離脱し、以後は開閉制御装置とは無関係にシャッタ2は上昇して行くことになる。バネ13の付勢により回動した施錠部材5は、規制突起15がケース8に当接する解錠位置で停止する。そして、保持部材6は嵌合棒16を施錠部材5上面に当接させた状態に、検知部材7は押圧突起21をリミットスイッチ20から完全に離隔させた状態に、それぞれ至ることになる。
【0021】
本発明の開閉制御装置は、掛止突起、施錠部材と保持部材との連携によりロック機構を構成し、施錠部材と検知部材との連携によりリミット機構を構成し、両者が適切に連動するようにしている。これは、施錠部材が両機構を介在させる部材として作動するためであり、この施錠部材が構造的にも両機構を兼ねることにより、本発明の開閉制御装置はコンパクトに一体化でき、設置作業を簡単にするのである。
【0022】
【発明の効果】
本発明の電動シャッタの開閉制御装置は、従来別体であったロック機構とリミット機構を一体にケースに納めることで設置作業を簡単にし、また両者が連動して作動するようにすることで、過度にシャッタが繰り出されることによるロック機構の破損を防止して、より安定かつ確実な施錠、解錠を実現するのである。

[Industrial applications]
The present invention relates to a control device for interlocking a lock mechanism and a limit mechanism of a shutter and positioning a lower limit of a shutter when an electric shutter for home use or the like is closed.
[0002]
[Prior art]
The electric shutter is very useful because it can be opened and closed mechanically, and is widely used not only for business use but also for home use. One of the purposes of using this electric shutter is to prevent crime. However, since the electric shutter for home use is relatively lightweight and the shutter is normally urged in the opening direction by a spring or the like, manual operation is required. The shutter that has been closed can be lifted and opened, so that a lock mechanism that locks the shutter when the shutter is closed is conventionally provided.
[0003]
The electric shutter requires not only a lock mechanism for closing the shutter but also a limit mechanism for preventing the opening / closing motor and the slats from being damaged by the opening / closing motor extending the shutter excessively. As the limit mechanism, there is known a method of measuring the number of rotations of an opening / closing motor and controlling a feeding amount of a shutter.
[0004]
In addition, as an example of the limit mechanism, there is Japanese Utility Model Publication No. Sho 50-6992, "Automatic Stopper for Electric Shutter". In this method, a magnet is attached to a shutter, and a micro reed switch detects that the shutter has reached the lowermost end from a change in a magnetic field caused by the magnet approaching as the shutter moves down, and stops the opening / closing motor.
[0005]
[Problems to be solved by the invention]
With a limit mechanism that measures the number of rotations of the rotation motor and controls the amount of extension of the shutter, proper operation is difficult, and if the size of the shutter changes, the relationship between the number of revolutions and the amount of extension of the shutter must be adjusted each time. This adjustment has to be performed at the site where the shutter is mounted, which is troublesome and reduces workability. Moreover, in the "automatic shutter for electric shutter", it is difficult to accurately detect a change in the magnetic field, and the shutter cannot be reliably stopped.
[0006]
Although the purpose of the lock mechanism is different from that of the limit mechanism, it is ideally desirable to stop the feeding of the shutter by operating the limit mechanism in a state in which the lock mechanism is securely locked. However, since the conventional lock mechanism and the limit mechanism are separate bodies, it is difficult to perform the adjustment for realizing the above-described interlocking, and in some cases, the shutter may stop even though it is not locked. is there.
[0007]
[Means for Solving the Problems]
In order to solve the above problem, a locking projection is provided on the shutter side edge, a locking member for locking the locking projection, a holding member for engaging with the locking member, and detection of rotation of the locking member. An opening / closing control device provided with a detection member to be provided on a shutter rail, wherein the locking member has a locking portion for locking the locking projection when the shutter reaches the lowermost limit, and a locking portion for locking the holding member. The locking portion is urged from a locking position where the locking projection locks the locking projection to an unlocking position where the locking portion releases the locking projection, so that the locking member is rotatable between the two states, and the holding member is a locking member. The lock member is urged toward the lock position to lock the lock member at the lock position, and releases the lock with the lock member in conjunction with the activation of the shutter opening / closing motor. Detects that the shutter has reached the locked position and activates the shutter open / close motor. Sealed so as to.
[0008]
[Action]
The operation of each part will be described in accordance with the lowering or raising of the shutter. When the shutter is lowered, the locking member is in the unlocked position by urging, the holding member urged toward this locking member cannot engage with the engaging portion of the locking member, and the locking member freely rotates toward the locking position. You can do it. When the shutter is further lowered, the locking projection starts to engage with the locking portion of the locking member, and the locking member is rotated toward the locking position by the locking projection in accordance with the lowering of the shutter. Then, when the shutter reaches the lowermost limit, the locking member reaches the locking position, and the holding member engages with the engaging portion to regulate the rotation of the locking member. For this reason, even if the shutter is raised in this state, the locking member whose rotation is restricted by the holding member locks the locking projection, so that the locking position can be maintained. At the same time, the detecting member detects the locked position of the locking member and stops the shutter opening / closing motor.
[0009]
When the shutter starts to rise by activation of the opening / closing motor, the holding member releases the engagement with the engaging portion in conjunction with the activation of the opening / closing motor, so that the locking member can freely rotate again. . Therefore, the locking projection is released from the locking portion as the shutter is raised, the locking member is returned to the unlocked position by the bias, and the shutter can be raised without any restraint.
[0010]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an electric shutter provided with the opening / closing control device of the present invention. As shown in FIG. 1, the electric shutter stores a shutter 2 in a shutter box 1 having a built-in opening / closing motor (not shown) at the top, and opens and closes by operating a switch (not shown). The opening / closing control device projects the latching projection 3 on the bottom slat 4, integrates the locking member 5, the holding member 6, and the detection member 7 into a case 8 (see FIG. 2 et seq.). It is arranged near the lower end of the rail 9.
[0011]
The opening / closing control device of the present invention has a limit mechanism for stopping the opening / closing motor so as to lock the shutter and prevent the opening / closing motor or the slats from being damaged by excessive opening / closing of the shutter. There is a feature. Considering this point, the operation procedure of the opening / closing control device will be described with reference to the drawings. FIGS. 2 to 4 are sectional views of the opening / closing control device showing the steps from closing the shutter 2 to locking, and FIGS. 5 to 7 showing the steps from unlocking and opening the shutter 2 in order.
[0012]
The structure of the opening / closing control device will be described with reference to FIG. The latching projections 3 are protruded from both sides of the bottom slat 4 so as to be able to extend and retract (toward the drawing in FIG. 2). The locking member 5 is a disk-shaped member having a locking portion 10 cut out toward the locking projection 3, and the locking portion 10 has an upward unlocking position (see FIG. 2) and a horizontal locking position. 4 (see FIG. 4), is pivotally mounted on a rotating shaft 11 provided on the case 8 and is urged toward an unlocking position by a spring 13 connecting the urging projection 12 and the case 8. ing. In addition, a groove 14 is provided on the upper surface of the locking member 5 for fitting the holding member 6, and in this embodiment, a regulating protrusion 15 that contacts the case 8 is provided so that the rotation to the locking position stops at a certain limit. It is provided between the hook 13 and the groove 14.
[0013]
The holding member 6 is composed of a solenoid 18 having a plunger 17 having a lower end formed with a fitting rod 16 fitted into the groove 14 of the locking member 5, and is urged downward by a coil spring 19 loosely fitted to the plunger 17. Have been. When the locking member 5 is at the unlocking position, the holding member 6 slides the fitting rod 16 on the upper surface of the locking member 5, and engages the fitting rod 16 with the groove 14 when the locking member 5 is at the locking position. However, when the solenoid 18 is operated in conjunction with the activation of the opening / closing motor, the plunger 19 moves upward, and the engagement between the locking member 5 and the holding member 6 is released regardless of the position of the groove 14.
[0014]
The detecting member 7 includes a limit switch 20 and a pressing protrusion 21. The pressing projection 21 is attached to the rotation shaft 11 and rotates according to the rotation of the locking member 5. Since it is only necessary to interlock with the rotation of the pressing protrusion 5, it may be provided integrally with the locking member 5. Thus, when the locking member 5 reaches the locking position, the pressing projection 21 that has rotated the limit switch 20 fixed to the case 8 is pressed, and the locking projection 3 is locked by the locking portion 10 of the locking member 5. That is, the locked position is detected, and the fact is output as an electric signal from the output lead wire 22 (see FIG. 4), and the opening / closing motor is stopped. As the detection member, a weak current is normally supplied to the solenoid, and a change in the magnetic field of the solenoid caused by engagement of the fitting rod with the groove of the locking member is detected to detect the completion of locking. May be.
[0015]
First, the steps from closing the shutter to locking will be described. FIG. 2 shows a state where the shutter 2 is lowered (closing procedure 1). Even when the shutter 2 is lowered, the locking member 5 is stopped at the unlocking position as long as the locking projection 3 does not contact the locking portion 10 of the locking member 5. The solenoid 18 of the holding member 6 is in a state where the fitting rod 16 is in contact with the upper surface of the locking member 5, and the plunger 17 is pushed upward. Further, since the pressing protrusion 21 constituting the detecting member 7 rotates downward and is separated from the limit switch 20, the opening / closing motor continues to operate, and the shutter 2 is further extended.
[0016]
FIG. 3 shows a state in which the locking projection 3 has begun to lock on the locking portion 10 of the locking member 5 (closing procedure 2). When the locking projection 3 abuts on the locking portion 10 and continues to descend, the locking member 5 starts rotating toward the locking position (left rotation in FIG. 3). Even if the locking member 5 starts rotating, the solenoid 18 of the holding member 6 merely slides the fitting rod 16 on the upper surface of the locking member 5 until the locking member 5 reaches the locking position, and the plunger 17 is still pushed upward. is there. Further, since the pressing protrusion 21 constituting the detecting member 7 approaches the limit switch 20 but does not yet press it, the opening / closing motor continues to operate.
[0017]
FIG. 4 shows a state in which the hooking projection 3 is completely hooked by the hooking portion 10 and at the same time the detection member 7 has sent a stop signal of the opening / closing motor (closing procedure 3). When the locking projection 3 is completely locked by the locking portion 10, that is, when the locking position is reached, the plunger 17 is lowered by the bias of the coil spring 19, and the fitting rod 16 engages with the groove 14 of the locking member 5. Thus, the holding member 6 restrains the locking member 5 at the locking position. Further, the pressing protrusion 21 constituting the detecting member 7 pushes the limit switch 20 to stop the opening / closing motor. Thus, the opening / closing control device of the present invention simultaneously realizes the locking of the extended shutter and the stopping of the opening / closing motor.
[0018]
Subsequently, a process from unlocking to opening the shutter will be described. FIG. 5 shows a state in which a hoist motor (not shown) is activated for the shutter 2 in the locked position, and at the same time, the solenoid 18 is excited (opening procedure 1). In the locked position, even if only the shutter 2 is lifted, it cannot be opened because the locking member 5 whose rotation is restricted by the holding member 6 locks the locking projection 3. However, a signal is sent to the input lead wire 23 simultaneously with the activation of the hoist motor (see FIG. 5), and the plunger 17 is pulled up by exciting the solenoid 18 to release the engagement between the fitting rod 16 and the groove 14 to lock. By releasing the constraint on the member 5, the shutter 2 can be wound up.
[0019]
FIG. 6 illustrates a state in which the locking member 5 is rotating toward the unlocking position (opening procedure 2). When the unlocked locking member 5 starts rotating toward the unlocking position by the bias of the spring 13, the position of the groove 14 of the locking member 5 is shifted with respect to the fitting rod 16 of the holding member 6. Even if the excitation of the solenoid 18 is released at this stage, the fitting rod 16 only comes into sliding contact with the upper surface of the locking member 5, but does not engage with the groove 14 again to restrict the rotation of the locking member 5. Further, at this stage, the pressing projection 21 constituting the detecting member 7 is separated from the limit switch 20. Therefore, if the switch is switched in a direction in which the shutter 2 is extended, the shutter 2 can be lowered until it is completely closed. it can.
[0020]
FIG. 7 shows a state in which the rotation of the locking member 5 has been completed and the locking member 5 has completely returned to the unlocked position (opening procedure 3). At this stage, the locking projection 3 is completely disengaged from the locking portion 10 of the locking member 5, and thereafter, the shutter 2 is raised independently of the opening / closing control device. The locking member 5 rotated by the bias of the spring 13 stops at the unlocking position where the regulating protrusion 15 contacts the case 8. Then, the holding member 6 reaches a state where the fitting rod 16 is in contact with the upper surface of the locking member 5, and the detection member 7 reaches a state where the pressing protrusion 21 is completely separated from the limit switch 20.
[0021]
The opening / closing control device according to the present invention is configured such that a locking mechanism is configured in cooperation with a locking protrusion, a locking member, and a holding member, and a limit mechanism is configured in cooperation with a locking member and a detection member, so that both are appropriately interlocked. ing. This is because the locking member operates as a member that interposes both mechanisms, and since the locking member also serves as both mechanisms structurally, the opening / closing control device of the present invention can be integrated compactly and installation work can be performed. Make it easy.
