That is, the second convex portion 54e is a portion that moves the lock member 63 to the unlocking position in response to the door opening operation by the door motor 15 when the car is landing on the landing floor.
　ここで、第１及び第２のかごドア２，３が全閉状態のときの第１及び第２のベーン５７，５８の位置を通常位置とする。また、第１及び第２のベーンが連結ローラ４５に接触して第１及び第２の乗場ドア３２，３３が第１及び第２のかごドア２，３に連動しているときの第１及び第２のベーン５７，５８の位置を連動位置とする。ロック部材６３は、第１及び第２のベーン５７，５８が通常位置から連動位置に移動する動作に連動して、施錠位置から解錠位置に回転する。 Here, the positions of the first and second vanes 57 and 58 when the first and second car doors 2 and 3 are in the fully closed state are defined as normal positions. In addition, the first and second vanes are in contact with the connecting roller 45, and the first and second landing doors 32, 33 are in the first and second car doors 2, 3 when the first and second car doors 2, 3 are linked. The positions of the second vanes 57 and 58 are set as interlocking positions. The lock member 63 rotates from the locked position to the unlocked position in conjunction with the movement of the first and second vanes 57, 58 from the normal position to the interlocked position.
　また、ロック部材６３は、第１のベーン５７と第２のベーン５８との間隔が、連結ローラ４５を挟み込んだときの間隔よりも大きい状態から小さくなる動作に連動して、施錠位置から解錠位置に回転する。 Further, the locking member 63 is unlocked from the locked position in conjunction with the operation in which the distance between the first vane 57 and the second vane 58 becomes smaller than the distance when the connecting roller 45 is sandwiched.

FIG. FIG. 9 is a front view of FIG. 8 with some components omitted.
　図３の状態から、保守員により、乗場ドア装置の錠装置が解錠され、第２の乗場ドア３３が手動で開方向へ動かされると、連結ローラ４５により第２のベーン５８が図３の左方向へ押される。これにより、第１のベーン５７と第２のベーン５８との間隔が広げられるとともに、連動部材５４が図３の時計方向へ回転する。また、作用軸５２ａは、保持ばね６４に抗して、スライド穴５４ａ内を第２の位置に移動する。 From the state of FIG. 3, when the locking device of the hall door device is unlocked by the maintenance staff and the second hall door 33 is manually moved in the opening direction, the second vane 58 of FIG. Pushed to the left. Thereby, the space between the first vane 57 and the second vane 58 is widened, and the interlocking member 54 rotates clockwise in FIG. The action shaft 52a moves to the second position in the slide hole 54a against the holding spring 64.
　そして、ピン６３ａがカム部５４ｂにより押されて、ロック部材６３が、ロック部材軸６２を中心として回転し、解錠位置に移動する。 ピ ン Then, the pin 63a is pushed by the cam portion 54b, and the lock member 63 rotates about the lock member shaft 62 and moves to the unlock position.
　このとき、ピン６３ａは、カム部５４ｂの第１の凸部５４ｃに接触している。即ち、第１の凸部５４ｃは、かごが乗場階に着床しているときに、手動による戸開動作に対して、ロック部材６３を解錠位置に移動させる部分である。 、 At this time, the pin 63a is in contact with the first convex portion 54c of the cam portion 54b. That is, the first convex portion 54c is a portion that moves the lock member 63 to the unlocking position in response to a manual door opening operation when the car is landing on the landing floor.
　この状態から、第２の乗場ドア３３を開方向へさらに動かすことにより、第１及び第２のかごドア２，３と第１及び第２の乗場ドア３２，３３とは、手動により開放動作させることができる。 By further moving the second landing door 33 in the opening direction from this state, the first and second car doors 2 and 3 and the first and second landing doors 32 and 33 are manually opened. be able to.
　次に、図１０は、かごが乗場階に着床しているときに、第１及び第２のかごドア２，３を手動で開方向へ動かそうとした場合のかごドア装置の要部を示す正面図である。また、図１１は、図１０の一部の部品を省略して示す正面図である。 Next, FIG. 10 shows a main part of the car door device when the first and second car doors 2 and 3 are manually moved in the opening direction when the car is landing on the landing floor. FIG. FIG. 11 is a front view of FIG. 10 with some parts omitted.
　図３の状態から、第１のかごドア２が手動で開方向へ動かされると、第１のベーン５７に連結ローラ４５が当たり、第１のベーン５７と第２のベーン５８との間隔が広げられるとともに、連動部材５４が図３の時計方向へ回転する。また、作用軸５２ａは、保持ばね６４に抗して、スライド穴５４ａ内を第２の位置に移動する。 When the first car door 2 is manually moved in the opening direction from the state shown in FIG. 3, the connecting roller 45 hits the first vane 57, and the distance between the first vane 57 and the second vane 58 is increased. At the same time, the interlocking member 54 rotates clockwise in FIG. The action shaft 52a moves to the second position in the slide hole 54a against the holding spring 64.
　そして、ピン６３ａがカム部５４ｂにより押されて、ロック部材６３が、ロック部材軸６２を中心として回転し、解錠位置に移動する。また、乗場ドア装置の錠装置も解錠される。このとき、ピン６３ａは、カム部５４ｂの第１の凸部５４ｃに接触している。 ピ ン Then, the pin 63a is pushed by the cam portion 54b, and the lock member 63 rotates about the lock member shaft 62 and moves to the unlock position. Further, the locking device of the landing door device is also unlocked. At this time, the pin 63a is in contact with the first protrusion 54c of the cam 54b.
　この状態から、第１のかごドア２を開方向へさらに動かすことにより、第１及び第２のかごドア２，３と第１及び第２の乗場ドア３２，３３とは、手動で開放動作させることができる。 By moving the first car door 2 further in the opening direction from this state, the first and second car doors 2 and 3 and the first and second landing doors 32 and 33 are manually opened. be able to.
　次に、図１２は、かごが階間に停止しているときに、第１又は第２のかごドア２，３を手動で開方向へ動かそうとした場合のかごドア装置の要部を示す正面図である。また、図１３は、図１２の一部の部品を省略して示す正面図である。 Next, FIG. 12 shows a main part of the car door apparatus when the first or second car door 2, 3 is manually moved in the opening direction when the car is stopped between floors. It is a front view. FIG. 13 is a front view of FIG. 12 with some components omitted.
　図１２及び図１３のように、かごが着床位置から外れている状態では、第１及び第２のベーン５７，５８間に連結ローラ４５が存在しない。このため、ロック部材６３は、施錠位置に位置したままであり、第１のベーン５７の開方向への移動は、ロック部材６３がラッチ６１に掛かることで阻止される。 As shown in FIGS. 12 and 13, when the car is out of the landing position, the connecting roller 45 does not exist between the first and second vanes 57 and 58. For this reason, the lock member 63 remains in the locked position, and the movement of the first vane 57 in the opening direction is prevented by the lock member 63 being hooked on the latch 61.
　このとき、ピン６３ａは、第１の凹部５４ｄに接触したままである。即ち、第１の凹部５４ｄは、かごが階間に停止しているときに、手動での戸開動作に対して、ロック部材６３を施錠位置に保持する部分である。 と き At this time, the pin 63a remains in contact with the first recess 54d. That is, the first concave portion 54d is a portion that holds the lock member 63 at the locked position against a manual door opening operation when the car is stopped between floors.
　次に、図１４は、かごが階間に停止しているときに、ドアモータ１５により第１及び第２のかごドア２，３を開方向へ動かそうとした場合のかごドア装置の要部を示す正面図である。また、図１５は、図１４の一部の部品を省略して示す正面図である。 Next, FIG. 14 shows a main part of the car door device when the first and second car doors 2 and 3 are moved in the opening direction by the door motor 15 when the car is stopped between floors. FIG. FIG. 15 is a front view of FIG. 14 with some components omitted.
　この場合、第１及び第２のベーン５７，５８間に連結ローラ４５が存在しない状態で、ドアモータ１５の駆動により把持部材２０が図１４の左方向へ移動する。そして、連動部材５４が図１４の反時計方向へ回転するとともに、第１のベーン５７と第２のベーン５８との間隔が狭くなる。 In this case, the driving of the door motor 15 moves the gripping member 20 leftward in FIG. 14 in a state where the connecting roller 45 does not exist between the first and second vanes 57 and 58. Then, the interlocking member 54 rotates in the counterclockwise direction in FIG. 14, and the interval between the first vane 57 and the second vane 58 is reduced.
　但し、連結ローラ４５が存在しないため、第１のベーン５７と第２のベーン５８との間隔は、連結ローラ４５を挟んだときの間隔よりも狭くなる。また、作用軸５２ａは、スライド穴５４ａ内で第１の位置に位置したままである。 However, since the connecting roller 45 does not exist, the distance between the first vane 57 and the second vane 58 is smaller than the distance when the connecting roller 45 is sandwiched. Further, the operation shaft 52a remains at the first position in the slide hole 54a.
　連動部材５４が回転することにより、ピン６３ａが第２の凸部５４ｅに接触し、ロック部材６３が解錠位置に回転する。しかし、連動部材５４がさらに回転することで、ピン６３ａは、第２の凸部５４ｅを通過して第２の凹部５４ｆに接する。これにより、ロック部材６３は、再び施錠位置に回転する。即ち、第２の凹部５４ｆは、かごが階間に停止しているときに、ドアモータ１５による戸開動作に対して、ロック部材６３を施錠位置に保持する部分である。 (4) When the interlocking member 54 rotates, the pin 63a comes into contact with the second protrusion 54e, and the lock member 63 rotates to the unlock position. However, when the interlocking member 54 further rotates, the pin 63a passes through the second protrusion 54e and comes into contact with the second recess 54f. Thereby, the lock member 63 rotates to the locked position again. That is, the second concave portion 54f is a portion that holds the lock member 63 in the locked position with respect to the door opening operation by the door motor 15 when the car is stopped between floors.
　このように、ロック部材６３は、第１及び第２のベーン５７，５８が連動位置から通常位置とは反対側へ移動する動作に連動して、解錠位置から施錠位置に回転する。また、ロック部材６３は、第１のベーン５７と第２のベーン５８との間隔が、連結ローラ４５を挟んだときの間隔よりも小さくなる動作に連動して、解錠位置から施錠位置に回転する。 As described above, the lock member 63 rotates from the unlocked position to the locked position in conjunction with the movement of the first and second vanes 57, 58 from the interlocked position to the opposite side from the normal position. Further, the locking member 63 rotates from the unlocking position to the locking position in conjunction with the operation in which the interval between the first vane 57 and the second vane 58 becomes smaller than the interval when the connecting roller 45 is sandwiched. I do.
　このようなエレベータのかごドア装置では、ロック部材６３は、ベーン機構１９に連動して施錠位置と解錠位置との間で回転する。また、ロック部材６３は、かごが乗場階に着床しているときにドアモータ１５により第１及び第２のかごドア２を開方向へ動かそうとした場合に、解錠位置に位置する。また、ロック部材６３は、かごが階間に位置しているときに、ドアモータ１５により第１及び第２のかごドア２を開方向へ動かそうとした場合に、施錠位置に位置する。 In such an elevator car door device, the lock member 63 rotates between the locked position and the unlocked position in conjunction with the vane mechanism 19. The lock member 63 is located at the unlock position when the door motor 15 attempts to move the first and second car doors 2 in the opening direction while the car is landing on the landing floor. The lock member 63 is located at the locked position when the door motor 15 attempts to move the first and second car doors 2 in the opening direction when the car is located between floors.
　このため、かごが階間に位置しているときに、第１及び第２のかごドア２，３の開方向への移動をより確実に抑制することができる。 Therefore, when the car is located between floors, the movement of the first and second car doors 2 and 3 in the opening direction can be more reliably suppressed.
　また、ロック部材６３は、第１及び第２のベーン５７，５８が通常位置から連動位置に移動する動作に連動して、施錠位置から解錠位置に回転する。また、ロック部材６３は、第１及び第２のベーン５７，５８が連動位置から通常位置とは反対側へ移動する動作に連動して、解錠位置から施錠位置に回転する。 (4) The lock member 63 rotates from the locked position to the unlocked position in conjunction with the movement of the first and second vanes 57, 58 from the normal position to the interlocked position. The lock member 63 rotates from the unlocked position to the locked position in conjunction with the movement of the first and second vanes 57, 58 from the interlocked position to the side opposite to the normal position.
　このため、かごが乗場階に着床しているときには、第１及び第２のかごドア２，３の開方向への移動を許容しつつ、かごが階間に位置しているときには、第１及び第２のかごドア２，３の開方向への移動をより確実に抑制することができる。 For this reason, when the car is landing on the landing floor, the first and second car doors 2 and 3 are allowed to move in the opening direction, and when the car is located between the floors, In addition, the movement of the second car doors 2 and 3 in the opening direction can be more reliably suppressed.
　また、ロック部材６３は、第１のベーン５７と第２のベーン５８との間隔が、連結ローラ４５を挟み込んだときの間隔よりも大きい状態から小さくなる動作に連動して、施錠位置から解錠位置に回転する。また、ロック部材６３は、第１のベーン５７と第２のベーン５８との間隔が、連結ローラ４５を挟んだときの間隔よりも小さくなる動作に連動して解錠位置から施錠位置に回転する。 Further, the locking member 63 is unlocked from the locked position in conjunction with the operation in which the distance between the first vane 57 and the second vane 58 becomes smaller than the distance when the connecting roller 45 is sandwiched. Rotate to the position. Further, the lock member 63 rotates from the unlocking position to the locking position in conjunction with the operation in which the interval between the first vane 57 and the second vane 58 becomes smaller than the interval when the connecting roller 45 is sandwiched. .
　このため、かごが乗場階に着床しているときには、第１及び第２のかごドア２，３の開方向への移動を許容しつつ、かごが階間に位置しているときには、第１及び第２のかごドア２，３の開方向への移動をより確実に抑制することができる。 For this reason, when the car is landing on the landing floor, the first and second car doors 2 and 3 are allowed to move in the opening direction, and when the car is located between the floors, In addition, the movement of the second car doors 2 and 3 in the opening direction can be more reliably suppressed.
　また、ロック部材６３は、第１及び第２のベーン５７，５８のいずれか一方が、連結ローラ４５に接触した状態で、通常位置から連動位置とは反対側へ移動する動作に連動して、施錠位置から解錠位置に回転する。 Further, the lock member 63 is linked with the operation of moving one of the first and second vanes 57 and 58 from the normal position to the opposite side to the interlocking position in a state of contact with the connecting roller 45, Rotate from the locked position to the unlocked position.
　このため、かごが乗場階に着床しているときに、第１のかごドア２、第２のかごドア３、第１の乗場ドア３２、及び第２の乗場ドア３３のいずれかを手動で動かそうとした場合にも、ロック部材６３を解錠位置に回転させることができる。 Therefore, when the car is landing on the landing floor, one of the first car door 2, the second car door 3, the first landing door 32, and the second landing door 33 is manually operated. Even when the user tries to move the lock member 63, the lock member 63 can be rotated to the unlock position.
　また、ベーン機構１９には、ベーン機構１９に連動してロック部材６３を回転させるカム部５４ｂが設けられている。このため、簡単な構成により、ロック部材６３をベーン機構１９に連動して回転させることができる。 カ ム Further, the vane mechanism 19 is provided with a cam portion 54 b that rotates the lock member 63 in conjunction with the vane mechanism 19. Therefore, with a simple configuration, the lock member 63 can be rotated in conjunction with the vane mechanism 19.
　また、カム部５４ｂを連動部材５４に設けたので、簡単な構成により、ロック部材６３をベーン機構１９に連動して回転させることができる。 Further, since the cam portion 54b is provided on the interlocking member 54, the lock member 63 can be rotated in conjunction with the vane mechanism 19 with a simple configuration.
　また、連動部材５４とロック部材６３との間に、調整機構が不要である。また、カム部５４ｂ及びロック部材６３を精度良く加工することで、より適正なタイミングでロック部材６３を施錠位置と解錠位置との間で回転させることができる。 調整 Further, no adjusting mechanism is required between the interlocking member 54 and the lock member 63. Further, by processing the cam portion 54b and the lock member 63 with high precision, the lock member 63 can be rotated between the locked position and the unlocked position at more appropriate timing.
　また、第１のかごドア２が全閉状態のとき、作用軸５２ａは、第１の位置に位置している。また、連動部材５４とレバー５２との間には、作用軸５２ａを第１の位置に保持する力が加えられている。 作用 When the first car door 2 is in the fully closed state, the operation shaft 52a is located at the first position. Further, a force for holding the operation shaft 52a at the first position is applied between the interlocking member 54 and the lever 52.
　このため、かごの走行時に、ロック部材６３をより確実に施錠位置に保持することができる。また、かごが階間に位置しているときには、第１及び第２のかごドア２，３の開方向への移動をより確実に抑制することができる。また、かごの走行時に、ベーン機構１９の振動を抑制することができる。 た め Therefore, when the car travels, the lock member 63 can be more reliably held at the locked position. Further, when the car is located between floors, the movement of the first and second car doors 2 and 3 in the opening direction can be more reliably suppressed. In addition, vibration of the vane mechanism 19 can be suppressed when the car travels.
　また、作用軸５２ａは、かごが乗場階に着床しているときにドアモータ１５により第１及び第２のかごドア２，３を開方向へ動かそうとした場合に、第２の位置に移動される。このため、第１及び第２のかごドア２，３と第１及び第２の乗場ドア３２，３３とをより確実に連動させることができる。 The action shaft 52a moves to the second position when the door motor 15 attempts to move the first and second car doors 2 and 3 in the opening direction while the car is landing on the landing floor. Is done. For this reason, the 1st and 2nd car doors 2 and 3 and the 1st and 2nd landing doors 32 and 33 can be linked more reliably.
　また、作用軸５２ａは、かごが乗場階に着床しているときに、手動により第１及び第２のかごドア２，３のいずれか、又は第１及び第２の乗場ドア３２，３３のいずれかを開方向へ動かそうとした場合に、第２の位置に移動される。このため、第１及び第２のかごドア２，３と第１及び第２の乗場ドア３２，３３とをより確実に連動させることができる。 Further, when the car is landing on the landing floor, the action shaft 52a manually moves one of the first and second car doors 2 and 3 or the first and second landing doors 32 and 33. If any of them are to be moved in the opening direction, they are moved to the second position. For this reason, the 1st and 2nd car doors 2 and 3 and the 1st and 2nd landing doors 32 and 33 can be linked more reliably.
