次に、前記装置の動作について説明する。
図３は乗場ドア５４が閉鎖し施錠されている状態を示している。エレベータかごが乗場に着床し、かごドアが乗場ドア５４に対面すると、かごドアの係合板９０，９１は二点鎖線で示す位置にくる。
そして、かごドアが開き始めると、固定係合板９０は図３の右方（戸開方向）に移動し解錠ローラ８０に接触する。更にかごドアが開いて固定係合板９０が右方に移動すると、解錠ローラ８０は右方に押され、作動体６３は圧縮ばね８３を圧縮して時計方向に回転し、補助ローラ８１が固定係合板９０に接触する。この回転により、鉤６６は固定片７１から外れ、またコンタクト６７は接点７３から離れる。
これにより、スイッチ７２がオフとなりエレベータの昇降を不能にするとともに、乗場ドア５４は開放可能となる。 Next, the operation of the apparatus will be described.
FIG. 3 shows a state where the landing door 54 is closed and locked. When the elevator car reaches the landing and the car door faces the landing door 54, the engagement plates 90 and 91 of the car door come to the positions indicated by the two-dot chain lines.
When the car door begins to open, the fixed engagement plate 90 moves to the right (door opening direction) in FIG. 3 and contacts the unlocking roller 80. When the car door further opens and the fixed engagement plate 90 moves to the right, the unlocking roller 80 is pushed to the right, the operating body 63 compresses the compression spring 83 and rotates clockwise, and the auxiliary roller 81 is fixed. Contact the engaging plate 90. By this rotation, the collar 66 is detached from the fixed piece 71 and the contact 67 is separated from the contact 73.

Thereby, each roller 80, 81, 82 of a landing is pinched | interposed by the engagement plates 90 and 91 of a cage | basket | car from both sides, and both doors of a cage | basket and a landing open integrally. When closing, the reverse operation is performed.

実公平１−３６８６６号公報Japanese Utility Model Publication 1-36866

保守時やかご内乗客の救出時に、乗場から乗場ドア５４（又はかごドアと乗場ドアの両方）を開く場合には、解錠キーを用いて、作動体６３を図３の時計方向に回転し、鉤６６と固定片７１の係合を外して乗場ドア５４（又はかごドアと乗場ドアの両方）を開けるようになっている。
しかしながら、解錠キーを用いずに乗場ドア５４を開けようとした場合、強い力で乗場ドア５４を開けようとすると、ドアロックの構造によっては、鉤６６と固定片７１の係合が外れる可能性が懸念される。 When the landing door 54 (or both the car door and the landing door) is opened from the landing during maintenance or when the passenger in the car is rescued, the operating body 63 is rotated clockwise in FIG. 3 using the unlocking key. The landing door 54 (or both the car door and the landing door) is opened by disengaging the hook 66 and the fixed piece 71.
However, when trying to open the landing door 54 without using the unlocking key, if the landing door 54 is opened with a strong force, the hook 66 and the fixed piece 71 may be disengaged depending on the structure of the door lock. There is concern about sex.

この問題を図５により説明する。図５は図３の要部説明図である。解錠キーを使わずに乗場ドア５４を開けようとすると、鉤６６と固定片７１との係合部の上下長さｘの中央Ａ点において、鉤６６は固定片７１から垂直抗力Ｐを受ける。このとき、作動体６３の軸８４の位置がＡ点よりもｙだけ高い位置にあると、作動体６３の軸８４に時計方向のモーメントが発生し、鉤６６と固定片７１との係合を外す方向の力として働く。
そのため、時計方向のモーメントを発生させない又は時計方向のモーメントをできる限り小さくする必要がある。 This problem will be described with reference to FIG. FIG. 5 is an explanatory view of the main part of FIG. When the landing door 54 is opened without using the unlocking key, the hook 66 receives the vertical drag P from the fixed piece 71 at the center A of the vertical length x of the engaging portion of the hook 66 and the fixed piece 71. . At this time, if the position of the shaft 84 of the actuating body 63 is higher than the point A by y, a clockwise moment is generated on the shaft 84 of the actuating body 63, and the hook 66 and the fixed piece 71 are engaged. It works as a force to remove.
For this reason, it is necessary not to generate a clockwise moment or to reduce the clockwise moment as much as possible.

この対策として、軸８４を下げる、Ａ点を上げる、鉤６６と固定片７１との係合部を傾斜させ垂直抗力Ｐが軸８４回りに時計方向のモーメントを発生させないようにする、などが考えられる。
しかし、軸８４を下げたり、鉤６６と固定片７１との係合部を傾斜させる方法は、作動体６３の大幅な改造になるため、従来装置との互換性がなくなったりコストアップになるという問題がある。 Possible countermeasures include lowering the shaft 84, raising the point A, and tilting the engaging portion between the flange 66 and the fixed piece 71 so that the vertical drag P does not generate a clockwise moment around the shaft 84. It is done.
However, the method of lowering the shaft 84 or inclining the engaging portion between the flange 66 and the fixed piece 71 is a significant modification of the operating body 63, so that the compatibility with the conventional device is lost and the cost is increased. There's a problem.

そこで、作動体６３はそのままとし、固定片７１を改造することによってＡ点を上げる方法が考えられている。
図６は固定片７１の先端を戸開方向と逆方向に曲げたものである。これにより、固定片７１の先端が鉤６６と接触することになるため、鉤６６と固定片７１との係合部の上下方向の中央Ａ点を図５よりも上昇させることができる。
また図７は、固定片７１の先端部の一部を戸開方向と逆方向に突出させたものであり、鉤６６と固定片７１との係合部の上下長さｚを、ｚ＜ｘとしたものである。これは例えばハーフパンチによって比較的容易に加工できる。これにより、鉤６６と固定片７１との係合部の上下方向の中央Ａ点を図５よりも上昇させることができる。 Therefore, a method is considered in which the operating body 63 is left as it is, and the point A is raised by remodeling the fixed piece 71.
FIG. 6 shows the end of the fixed piece 71 bent in the direction opposite to the door opening direction. Thereby, since the front-end | tip of the fixed piece 71 contacts the collar 66, the center A of the up-down direction of the engaging part of the collar 66 and the fixed piece 71 can be raised rather than FIG.
FIG. 7 shows a part of the tip of the fixed piece 71 protruding in the direction opposite to the door opening direction. The vertical length z of the engaging portion between the flange 66 and the fixed piece 71 is expressed as z <x It is what. This can be processed relatively easily by, for example, a half punch. Thereby, the center A point of the up-down direction of the engaging part of the collar 66 and the fixed piece 71 can be raised rather than FIG.

前記の固定片７１の加工は、工場で加工する場合には有効な方法であるが、既に据え付けられているエレベータの場合には、スイッチボックス７０全体を取り外して加工しなければならないため、時間と費用が掛かるという問題がある。
そこで、本発明は、もっと簡単で外部から解錠されにくいドアロック装置を提供することを目的とするものである。 The processing of the fixed piece 71 is an effective method when processing at a factory, but in the case of an elevator that has already been installed, the entire switch box 70 must be removed and processed. There is a problem that it costs money.
Therefore, an object of the present invention is to provide a door lock device that is simpler and less likely to be unlocked from the outside.
