本発明は、エレベータの戸の開閉を制御する戸
開閉制御装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door opening/closing control device for controlling opening and closing of an elevator door.
従来、エレベータの戸開閉制御装置としては、
例えば第１図に示すようなものがある。 Conventionally, elevator door opening/closing control devices include:
For example, there is one shown in FIG.
この戸開閉制御装置においては、直流電動機１
で図示しないエレベータの戸を駆動するようにし
ている。 In this door opening/closing control device, a DC motor 1
This is used to drive the doors of an elevator (not shown).
そして、図示しないかごが指定階床に到着した
ときに戸開指令が発生されて、接点２ａ，２ｂが
閉成して、電源の＋側端子から抵抗４→接点２ａ
→直流電動機１→接点２ｂ→電源の−側端子の経
路で電流が流れて、直流電動機１が、例えば、矢
印Ａ方向に回転して、戸を全開させる。 Then, when the car (not shown) arrives at the designated floor, a door opening command is generated, contacts 2a and 2b are closed, and the + side terminal of the power supply is connected to resistor 4 → contact 2a.
A current flows through the path of →DC motor 1 →contact 2b →− side terminal of the power supply, and the DC motor 1 rotates in the direction of arrow A, for example, to fully open the door.
その後、一定時間が経過した時点で戸閉指令が
発生されて、接点２ａ，２ｂが開成して、接点３
ａ，３ｂが閉成し、今度は電源の＋側端子から抵
抗４→抵抗５→戸の全閉付近で開状態になる常閉
の位置スイツチ６→接点３ｂ→直流電動機１→接
点３ａ→電源の一側端子の経路で電流が流れて、
直流電動機１が例えば矢示Ｂ方向に回転して、戸
を全閉方向に移動させる。 After that, when a certain period of time has elapsed, a door close command is generated, contacts 2a and 2b open, and contact 3
a and 3b are closed, and this time from the + side terminal of the power supply, resistor 4 → resistor 5 → normally closed position switch 6, which becomes open near the door fully closed → contact 3b → DC motor 1 → contact 3a → power supply Current flows through the path of one side terminal of
The DC motor 1 rotates, for example, in the direction of arrow B to move the door in the fully closing direction.

の直流電動機に駆動電流を供給し続けて戸がこじ
開けられないようにした場合、こじ開けを防止す
るためには駆動電流を大きくして反こじ開け力を
大きくする必要があるが、大き過ぎると万が一乗
客の指等が戸と戸の間隙に挟まれたようなときに
は指等が圧迫されて負傷する恐れがあるので、戸
閉力（反こじ開力）を余り大きくすることはでき
ない。 By the way, if you continue to supply drive current to the DC motor for opening and closing the door while driving after the door is closed to prevent the door from being pried open, the drive current must be increased to prevent the door from being pried open. It is necessary to increase the force, but if the force is too large, if a passenger's fingers are caught between the doors, they may be compressed and injured. force) cannot be made too large.
このように、従来の戸開閉制御装置において
は、大きすぎない戸閉力を得なければならないと
いう極めて困難な問題があつた。 As described above, conventional door opening/closing control devices have had the extremely difficult problem of having to obtain a door closing force that is not too large.
本発明は上記の問題を解消するもので、戸全閉
状態で戸閉力が零で且つ大きな反こじ開力を得ら
