【考案の詳細な説明】
この考案はエレベータの戸の異常を警報する装置に関す
るものである。[Detailed description of the invention] This invention relates to a device that warns of an abnormality in an elevator door.
一般に、エレベータのドア装置は乗場の戸は通常施錠装
置により施錠されかごの戸が駆動装置によって開閉され
ると、乗場の戸は施錠装置が解錠されてかごの戸に係合
して開閉される。Generally, in an elevator door system, the landing door is normally locked by a locking device, and when the car door is opened and closed by a drive device, the landing door is opened and closed by the locking device being unlocked and engaging with the car door. Ru.
かごの戸には施錠装置がないのが一般的で、かごの走行
時には全閉されたかごの戸が駆動電動機により戸閉方向
に付勢されて全閉位置に保持される。Generally, the car door does not have a locking device, and when the car is running, the fully closed car door is biased in the closing direction by the drive motor and held in the fully closed position.
しかし、エレベータに何らかの異常が生じ、安全装置又
は異常検出装置が動作してかごが非常停止したとき、又
は停電等が発生してかごが急停止したときには、戸の駆
動装置の電源がしゃ断されかごの戸を戸閉方向に付勢す
る力が断たれるため、かごの戸はかご内の乗客によって
開かれる虞れがある。However, if some abnormality occurs in the elevator and the safety device or abnormality detection device operates and the car comes to an emergency stop, or if the car suddenly stops due to a power outage, etc., the power to the door drive device is cut off and the car stops. Since the force urging the car door in the closing direction is cut off, there is a risk that the car door may be opened by a passenger inside the car.
一方、階と階の中間においては、かごと昇降路壁の間に
は通常１５〜２０ｃｍのすき間があるので、かごがたま
たまこの階と階の中間に停止したとき、かご内の乗客が
かごの戸を開くと上記すき間から昇降路へ転落する危険
がある。On the other hand, between floors, there is usually a gap of 15 to 20 cm between the car and the hoistway wall, so if the car happens to stop between floors, the passengers inside the car can If you open the door, there is a risk of falling into the hoistway through the abovementioned gap.
また、酔客等が乗場の戸をたたくために施錠装置が外れ
て、乗場の戸を手で開くことが可能となってしまうこと
がある。Further, the locking device may come off due to a drunk passenger knocking on the landing door, making it possible for the door to be opened by hand.
このとき、酔客等が手で乗場の戸を開くと、かごがその
階にいないと昇降路に転落することがある。At this time, if a drunk passenger or the like manually opens the door to the landing, the car may fall into the hoistway if the car is not on that floor.
酔客のいたずらでなくても、エレベータの管理人や保守
員が解錠キーにより乗場の戸の錠を外して点検すること
があるが、このときかごの停止位置を確認することを怠
って、かごがその階に着床しているものと速断して乗場
の戸を開いたため、昇降路へ転落する事故も時々発生す
る。Even if it is not a prank by a drunk passenger, the elevator manager or maintenance worker may use the unlock key to unlock the landing door and inspect it. Occasionally, accidents occur in which passengers who are already on the floor quickly open the landing door and fall into the hoistway.
この考案は上記不具合を改良するもので、かごが正常停
止区間外に停止したときに、又はかごの走行中にかごの
戸又は乗場の戸が開かれたとき、乗客に手動戸開きをや
めさせるように警告するエレベータの戸の異常警報装置
を提供することを目的とする。This invention improves the above-mentioned problem by forcing passengers to stop manually opening the door when the car stops outside the normal stop zone, or when the car door or landing door is opened while the car is running. The purpose of the present invention is to provide an elevator door abnormality warning device that warns of the following.
以下、図によりこの考案の一実施例を説明する。An embodiment of this invention will be described below with reference to the drawings.

位置検出スイッチ、１Ｌは１階の乗場の戸が全開施錠さ
れたとき開放する乗場の戸スイッチ、２Ｌ、３Ｌは同じ
く２階及び３階の乗場の戸スイッチ、１Ｂは１階の乗場
の戸の付近に設置されたベル等の乗場警報器、２Ｂ、３
Ｂはそれぞれ２階及び３階の乗場警報器である。In the figure, (+) and (-) are DC uninterruptible power supplies powered by storage batteries, etc., 1 is a door-openable zone detection switch that opens when the car (not shown) reaches the door-openable zone, and 2
A car door switch that opens when the car door is fully closed.
3 is an automatic-manual changeover switch that automatically starts when the car responds to a call, closes during automatic operation when the car lands and opens the door, and opens during elevator installation or maintenance operations; 4 is the car door. An alarm such as a bell installed nearby or on the car,
1F is the 1st floor car position detection switch that opens when the car arrives on the 1st floor, 2F and 3F are the same car position detection switches on the 2nd and 3rd floors, and 1L is opened when the 1st floor landing door is fully opened and locked. 2L and 3L are the door switches for the landings on the 2nd and 3rd floors, 1B is the hall alarm such as a bell installed near the landing door on the 1st floor, 2B, 3
B are hall alarms on the second and third floors, respectively.
今、自動−手動切換スイッチ３は閉成されているものと
する。It is assumed that the automatic-manual changeover switch 3 is now closed.
かごが戸開き可能ゾーンに停止していると検出スイッチ
１は開放しているので、かごの戸の開閉に関係なく警報
器４は鳴動しない。Since the detection switch 1 is open when the car is stopped in the zone where the door can be opened, the alarm 4 does not sound regardless of whether the car door is opened or closed.
また、かごが例えば１階に停止していると検出スイッチ
１Ｆは開放しているので乗場の戸の解錠に関係なく警報
器１Ｂは鳴動しない。Further, when the car is stopped on the first floor, for example, the detection switch 1F is open, so the alarm 1B does not sound regardless of whether the landing door is unlocked.
他の階も同様である。またかごの走行中は、かごの戸ス
イッチ２及び乗場の戸スイッチ１Ｌ〜３Ｌはすべて開放
しているので警報器４，１Ｂ〜３Ｂはいずれも鳴動しな
い。The same applies to other floors. Furthermore, while the car is running, the car door switch 2 and the landing door switches 1L to 3L are all open, so none of the alarms 4, 1B to 3B sound.
今、かごの走行中、停電とかエレベータ安全装置の動作
によりかごが急停止して階と階の間に停止したとする。Now, suppose that while the car is running, the car suddenly stops due to a power outage or the activation of an elevator safety device and comes to rest between floors.
このとき、かご内の乗客が手でかごの戸を開けるとかご
の戸スイッチ２は開底する。At this time, when a passenger in the car opens the car door by hand, the car door switch 2 opens.
戸開き可能ゾーン検出スイッチ１は開底しているから、
（剖３−２−ｌ−４−（−）の回路により、警報器４が
鳴動し、乗客に対し戸を開くことは危険であるからやめ
ることを警告する。Since the door opening possible zone detection switch 1 is open,
(The circuit 3-2-l-4-(-) causes the alarm 4 to sound, warning passengers not to open the door as it is dangerous.
このとき放送とが表示灯等の警報装置によって危険を報
知すればいっそう望ましいことは言うまでもない。Needless to say, it would be even more desirable if the announcement was made by using an alarm device such as an indicator light to notify the danger.
次に、かごが３階に停止しているとすると、かご位置検
出スイッチ３Ｆは開放し、がご位置検出スイッチ、ＩＦ
、２Ｆは開底している。Next, assuming that the car is stopped on the third floor, the car position detection switch 3F is opened, and the car position detection switch 3F is opened.
, 2F is open bottom.
このとき、酔客等が１階の戸をたたいたため、１階の乗
場の戸の施錠が外れたとすると、乗場の戸スイッチＩＬ
は開底する。At this time, if the landing door on the first floor becomes unlocked because a drunk passenger knocks on the door on the first floor, the landing door switch IL
is open bottom.
ここで、（＋）−１１−１Ｌ−ＩＢ−←）の回路により
、警報器１Ｂが鳴動し、戸を開くことは危険であるから
やめることを警告する。Here, the circuit (+)-11-1L-IB-←) causes the alarm 1B to sound, warning the user not to open the door as it is dangerous.
なお、警報器１Ｂ〜３Ｂを各階ごとに設けず、複数階分
をまとめて１個とし、これを昇降路等に設置すれば、更
に経済的となる。In addition, it will be more economical if the alarm devices 1B to 3B are not provided for each floor, but are combined into one alarm device for a plurality of floors, and installed in the hoistway or the like.
また、上記のようにかごの戸が開いたとき、乗場の戸が
解錠するか又は開いたとき、管理人室等へも警報するよ
うにしてお・けば、異常の発見が早く、事故を未然に防
止できる。In addition, if the car door is opened or the landing door is unlocked or opened, an alarm is sent to the manager's room, etc., as described above, so that abnormalities can be discovered quickly and accidents can occur. can be prevented from occurring.
以上説明したとおりこの考案では、かごの戸及び乗場の
戸が互いに係合しない状態でかごの戸が少しでも開くと
警報を発し、またかごが階床に到着していない状態で乗
場の戸が解錠されると上記とは別に警報を発するように
したので、かごが戸開不能区間に停止したとき乗客がか
ご内から戸を開こうとすると、戸を開くことは危険であ
るからやめることを警告し、乗客が昇降路へ転落する重
大な事故を未然に防止することができる。As explained above, with this device, if the car door and the landing door are not engaged with each other and the car door opens even a little, an alarm will be issued, and if the car door has not reached the floor, the landing door will open. When the car is unlocked, a separate alarm is issued, so if the car stops in an area where the door cannot be opened and passengers try to open the door from inside the car, they are advised not to do so as it is dangerous. This can prevent serious accidents such as passengers falling into the hoistway.
また、係員等が乗場から昇降路へ転落する事故も未然に
防止することができる。Furthermore, accidents in which an attendant or the like falls from the landing onto the hoistway can be prevented.
