度に初圧を与えナツト２１で固定されている。17b', and the other end is connected to the drive arm 15.
9 is screwed into the insertion end of the second member 18 to ensure a required gap G3 between the protrusion 17a and the increased diameter part 18a, and the second member 18
a nut, 2 for holding in place relative to the first member 17 of the
Reference numeral 0 designates a compression spring, which is inserted through the second member 18, one end of which abuts against the protrusion 17a, and is fixed with a nut 21 with initial pressure applied to the extent that it will not be compressed by normal door opening/closing resistance.
２２は第１部材１７に装着され押しバネ２０が圧縮され
た時の第２部材１８の変位によって動作するドアー安全
装置のスイッチである。Reference numeral 22 denotes a door safety device switch attached to the first member 17 and operated by the displacement of the second member 18 when the push spring 20 is compressed.
今、エレベータが目的の階へ到着したとすると、戸開指
令が発せられて駆動機１１が駆動され、クランク１２が
第２図において時計方向に回転を始め、駆動力は第１、
第２部材１７．１８を経由し駆動腕１５に伝達され、駆
動腕１５も時計方向に回転しかどの戸９が開かれる。Assuming that the elevator has now arrived at the destination floor, a door opening command is issued, the driving machine 11 is driven, the crank 12 begins to rotate clockwise in FIG. 2, and the driving force is the first,
The signal is transmitted to the drive arm 15 via the second member 17, 18, and only when the drive arm 15 also rotates clockwise will any door 9 be opened.
同時に乗場の戸１も係合片１０及び係合装置３によシ開
かれ乗客の出入りが行われ所定時間後、１駆動機１１に
逆転指令が与えられ、クランク１１が反時計方向に回転
を始め、戸閉動作を開始する。At the same time, the landing door 1 is opened by the engaging piece 10 and the engaging device 3 to let passengers in and out.After a predetermined period of time, a reverse rotation command is given to the driving machine 11, and the crank 11 rotates counterclockwise. The door begins to close.
との戸閉動作中に、かごの戸９及び乗場の戸１に何ら過
負荷が生じなければ、押しばね２０によシ第１、第２部
材１７．１８が所定の相対位置に保持されるのでスイッ
チ２２が動作せずかごの戸９及び乗場の戸１は全閉しエ
レベータは他階へ走行する。During the door closing operation, if no overload occurs on the car door 9 and the landing door 1, the first and second members 17 and 18 are held at predetermined relative positions by the push spring 20. Therefore, the switch 22 does not operate, the car door 9 and the landing door 1 are fully closed, and the elevator runs to another floor.
しかし戸閉動作中のかごの戸９又は乗場の戸１に乗客が

反転指令が発せられて乗客の負傷事故及び駆動装置の損
傷事故が未然に防止される。However, if a passenger comes into contact with the car door 9 or the landing door 1 while the door is closing, or if a pebble or the like gets into the guide groove and obstructs the closing operation, the holding force of the push spring 20 will be overloaded. As the first and second members 17 and 18 are displaced relative to each other in opposition to is prevented.
しかしエレベータ走行中は他の安全上の理由からスイッ
チ２２が制御回路から切離されているため、乗客がいた
ずらでかごの戸９を隙間Ｇ３がＯになるまでこじ開ける
と、係合装置３と係合片１０の隙間Ｇ１が減少し、係合
装置３と係合片１０が干渉し損傷して係合不能となる不
具合が考えられる。However, while the elevator is running, the switch 22 is disconnected from the control circuit for other safety reasons, so if a passenger pries open the car door 9 until the gap G3 becomes O, the engagement device 3 and the There is a possibility that the gap G1 between the mating pieces 10 is reduced, and the engagement device 3 and the engagement pieces 10 interfere with each other and are damaged, making it impossible to engage them.
また損傷に到らなくても干渉によって大きな音を発し乗
客に無用な恐怖心を与える不具合があった。In addition, even if no damage was caused, the interference produced a loud noise that caused unnecessary fear to passengers.
また、かごの戸９をこじ開けるのに必要な力は駆動機１
１を逆転させる力よシも小さいので、比較的容易にかご
の戸９をこじ開けることができ、このときに、かごの戸
９の戸締シスイッチ（図示しない）が動作してエレベー
タが無用に停止する不具合も生じる。Also, the force required to pry open the car door 9 is the force required by the driver 1.
Since the force required to reverse the direction 1 is small, the car door 9 can be pried open relatively easily, and at this time, the door lock switch (not shown) of the car door 9 operates, rendering the elevator useless. Problems such as stopping may also occur.
この発明は上記の欠点を解消するもので、ドアー装置に
設けられたドアー安全装置を戸の全閉時には動作しない
ようにしたエレベータ用ドアー装置を提供しようとする
ものである。The present invention aims to solve the above-mentioned drawbacks and provides an elevator door device in which a door safety device provided on the door device does not operate when the door is fully closed.
以下第３図、第４図によってこの発明の一実施例を説明
する。An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.
図中、第１、第２図と同符号は同一部分を示し、２３は

レベータの走行指令装置である。Reference numeral 25 denotes a blocking detection body consisting of a switch attached to the tip of the support fitting 23 and having an actuating part in contact with the blocking body 24a;
25a is the normally open contact of this, 22a is the normally closed contact of the switch 22, 26 is the door control device, 27 is the normally open contact of the electromagnetic relay that is energized when the car door 9 is fully closed, and 28 is the normally open contact of the elevator. It is a driving command device.
今、かごの戸９が全閉したとすると、接点２７が閉成さ
れ（ト）−２７−２４−に）の回路によって阻止装置２
４が付勢される。Now, if the car door 9 is fully closed, the contact 27 is closed and the blocking device 2
4 is energized.
これによって阻止体２４ａが隙間Ｇ３内に突出するので
、かごの戸９がこじ開けられようとしても、第１、第２
部材１７．１８が相対変位しない。As a result, the blocking body 24a protrudes into the gap G3, so that even if the car door 9 is attempted to be forcibly opened, the first and second
There is no relative displacement of members 17,18.
これによって、かごの戸９が全閉位置に保持されるので
、エレベータの走行中にかごの戸９がいたずらされて生
じる不具合を未然に防止することができる。As a result, the car door 9 is held in the fully closed position, so that problems caused by tampering with the car door 9 while the elevator is running can be prevented.
また、阻止体２４ａの突出によって阻止検出体２５が動
作して接点２５ａが閉成され（ト）−２５ａ−２８−（

体２４ａを備えた阻止装置である。FIG. 5 shows another embodiment of the present invention. In the figure, the same reference numerals as in FIGS. 3 and 4 indicate corresponding parts, and L7 is connected to the drive force transmission mechanism 12 on the drive machine 11 side consisting of a chain. The connected first member 18 is a second member protruding from the banger 8 and placed on the car door 9 side, and 24 is a gap G3 between the first and second members 17 and 18 when energized. This is a blocking device equipped with a blocking body 24a that protrudes from the outside.
すなわち、かごの戸９が全閉されたとき阻止体２４ａが
隙間Ｇ３に突出して第１、第２部材１７゜１８の相対変
位を阻止する。That is, when the car door 9 is fully closed, the blocking body 24a protrudes into the gap G3 to prevent relative displacement of the first and second members 17 and 18.
したがって詳細な説明を省略するが、この実施例におい
ても、第３、第４図の実施例と同様な作用が得られるこ
とは白である。Therefore, although a detailed explanation will be omitted, it is clear that this embodiment also provides the same effect as the embodiments shown in FIGS. 3 and 4.
