The control device 34 receives signals from various sensors (such as a cab position sensor, distance sensors 31a and 31b, a force speed sensor, and a door sensor).
[0029] 次に、動作について説明する。第 1及び第 2の力ご 7, 8は、駆動装置 2の駆動力に より昇降路 1内を昇降される。第 1及び第 2の力ご室 14, 15は、通常は第 1の位置に 位置し前後に並んでいる。これに対し、第 1のかご 7と第 2のかご 8とがすれ違う際に は、第 1及び第 2の力ご室 14, 15は第 2の位置に移動されて上下に隣接する。  Next, the operation will be described. The first and second force bars 7 and 8 are raised and lowered in the hoistway 1 by the driving force of the driving device 2. The first and second force chambers 14 and 15 are normally located in the first position and lined up in the front and rear. On the other hand, when the first car 7 and the second car 8 pass each other, the first and second force cages 14, 15 are moved to the second position and are adjacent to each other vertically.
[0030] 例えば、高層ビルにお 、てシャトル運転を実施する場合であれば、第 1及び第 2の 力ご室 14, 15の変位を比較的緩やかに行うことができ、乗り心地の低下を防止する ことができる。  [0030] For example, when a shuttle operation is performed in a high-rise building, the first and second cabs 14 and 15 can be displaced relatively slowly, which reduces the ride comfort. It can be prevented.
[0031] 第 1及び第 2のかご室 14, 15を第 1の位置力も第 2の位置へ移動させる場合、まず ねじ式昇降装置 17により第 1のかご室 14を下動させる。その後、歯車式送り装置 20 により第 2のかご室 15を前方へ移動させる。逆に、第 1及び第 2のかご室 14, 15を第 2の位置力 第 1の位置へ移動させる場合、まず歯車式送り装置 20により第 2のかご 室 15を後方へ移動させる。その後、ねじ式昇降装置 17により第 1の力ご室 14を上動 させる。  [0031] When the first and second car chambers 14, 15 are moved to the second position also with the first positional force, the first car chamber 14 is first moved down by the screw type lifting device 17. Thereafter, the second cab 15 is moved forward by the gear-type feeding device 20. Conversely, when the first and second car chambers 14 and 15 are moved to the second position force first position, the second car chamber 15 is first moved rearward by the gear-type feeding device 20. Thereafter, the first force chamber 14 is moved up by the screw type lifting device 17.
[0032] このような第 1及び第 2のかご室 14, 15の動作中は、内部ドア 27, 28は閉鎖されて いるのは勿論である。逆に、内部ドア 27, 28の閉鎖がドアセンサ等により確認される までは、第 1及び第 2のかご室 14, 15の移動は禁止される。内部ドア 27, 28は、乗 場階への停止時以外は原則として閉鎖するようにしても、第 1及び第 2の力ご室 14, 15が第 1の位置にあるときには開放するようにしてもよい。 [0033] また、距離センサ 31a, 31bにより検出された第 1及び第 2のかご 7, 8の距離が所定 の範囲内であるときに第 1及び第 2のかご室 14, 15が第 2の位置に移動していない 場合、第 1及び第 2の力ご 7, 8は緊急停止 (又は可能であれば最寄り階停止)される さらに、第 1及び第 2のかご 7, 8が異なる階に停止している状態であれば、第 1及び 第 2のかご 7, 8の距離によらず第 1及び第 2のかご室 14, 15を第 1の位置に移動さ せてもよいが、第 1及び第 2のかご 7, 8の距離が所定の範囲内であるときには、第 1 及び第 2のかご室 14, 15を第 2の位置に移動させるまでは、第 1及び第 2のかご 7, 8 の走行が禁止される。 [0032] Of course, during the operation of the first and second cabs 14, 15, the internal doors 27, 28 are closed. Conversely, the movement of the first and second cabs 14, 15 is prohibited until the closing of the internal doors 27, 28 is confirmed by a door sensor or the like. The internal doors 27 and 28 should be closed in principle except when stopped at the landing floor, but they should be opened when the first and second cabs 14 and 15 are in the first position. Also good. [0033] When the distance between the first and second cars 7 and 8 detected by the distance sensors 31a and 31b is within a predetermined range, the first and second car rooms 14 and 15 If not moved to position, the first and second force 7, 8 will be urgently stopped (or the nearest floor if possible) and the first and second cars 7, 8 will be on different floors. If the vehicle is stopped, the first and second car rooms 14, 15 may be moved to the first position regardless of the distance between the first and second cars 7, 8. When the distance between the first and second cars 7 and 8 is within the predetermined range, the first and second cars 7 and 7 are moved until the first and second car rooms 14 and 15 are moved to the second position. , 8 is prohibited.
[0034] このようなエレベータ装置では、第 1及び第 2のかご室 14, 15を第 1の位置に位置 させることにより、垂直投影面で第 1のかご 7が第 2のかご 8に重なるように配置するこ とができ、また第 1及び第 2のかご室 14, 15を第 2の位置に変位させることにより、第 2のかご 8とのすれ違いを可能とすることができる。従って、十分なかご床面積を確保 しつつ、昇降路スペースを削減することができる。し力も、第 1及び第 2のかご室 14, 15を第 1の位置に位置させれば、第 1及び第 2のかご室 14, 15を最上階及び最下 階の両方に停止させることができ、運行上の利便性の低下を防止することができる。  In such an elevator apparatus, the first car 7 and the second car 8 are overlapped with each other on the vertical projection plane by positioning the first and second car rooms 14 and 15 at the first position. Further, by displacing the first and second cabs 14 and 15 to the second position, it is possible to pass the second cab 8. Therefore, the hoistway space can be reduced while securing a sufficient car floor area. If the first and second cabs 14 and 15 are positioned at the first position, the first and second cabs 14 and 15 can be stopped on both the top floor and the bottom floor. It is possible to prevent a decrease in convenience in operation.
[0035] また、第 1及び第 2のかご室 14, 15は、第 1及び第 2のかご室 14, 15が第 1の位置 にあるときに互いに対向する第 1及び第 2の内部出入口と、第 1及び第 2の内部出入 口を開閉する第 1及び第 2の内部ドア 27, 28とを有しているので、第 1及び第 2のか ご室 14, 15間の移動の可否を適当に管理することができる。  [0035] The first and second car chambers 14, 15 include first and second internal entrances facing each other when the first and second car chambers 14, 15 are in the first position. The first and second internal doors 27 and 28 for opening and closing the first and second internal access ports are provided, so that the movement between the first and second cabs 14 and 15 is appropriately determined. Can be managed.
[0036] さらに、第 1及び第 2の内部ドア 27, 28は、それぞれ独立して開閉制御されるので 、第 1及び第 2のかご室 14, 15を第 2の位置に位置させた状態で、ダブルデッキエレ ベータと同様に第 1の乗場 11との間での乗客の乗降を可能とすることができる。即ち 、第 1及び第 2のかご室 14, 15が第 1及び第 2の位置のいずれにあっても、乗客の乗 降が可能であり、運行方法の自由度を向上させることができる。また、第 1及び第 2の 力ご室 14, 15を第 2の位置に位置させた状態で着床する場合、第 1及び第 2のかご 室 14, 15の間隔を階間寸法に応じて調整することもできる。  [0036] Furthermore, since the first and second inner doors 27, 28 are independently controlled to open and close, the first and second car chambers 14, 15 are positioned at the second position. As with a double deck elevator, passengers can get in and out of the first landing 11. That is, passengers can get on and off regardless of whether the first and second cabs 14 and 15 are in the first and second positions, and the degree of freedom of operation can be improved. In addition, when landing with the first and second cabs 14 and 15 positioned in the second position, the distance between the first and second cabs 14 and 15 is determined according to the floor dimensions. It can also be adjusted.
[0037] さらにまた、主ロープ 6の第 2の端部には、第 3のかご室 30を有する第 2のかご 8が 吊り下げられているので、輸送能力を大幅に向上させることができる。この例では、一 般的な構造のエレベータに比べて、約 1. 5倍の昇降路スペースで 2倍の輸送能力を 得ることができる。 [0037] Furthermore, at the second end of the main rope 6, there is a second car 8 having a third car room 30.
