[0015] 駆動装置 5及び張り車 9は、昇降路 1の垂直投影面において、力ご 2の領域外に配 置されている。力ご 2は、天井部 2bの位置が駆動装置 5の位置よりも高い位置となる 上限位置と、床部 2aの位置が張り車 9の位置よりも低い位置となる下限位置との間を 昇降可能になっている。 The driving device 5 and the tensioning wheel 9 are arranged outside the area of the force cage 2 on the vertical projection plane of the hoistway 1. The force 2 is between the upper limit position where the position of the ceiling 2b is higher than the position of the driving device 5 and the lower limit position where the position of the floor 2a is lower than the position of the tensioning wheel 9. It can be moved up and down.
[0016] なお、力ご 2を吊り下げて昇降路 1内を昇降させるための昇降機構 12は、駆動装置 5、主ロープ 8及び張り車 9を有している。昇降機構 12は、昇降路 1の垂直投影面に おいて、かご 2の領域外に配置されている。  Note that the lifting mechanism 12 for hanging the force 2 to move up and down in the hoistway 1 has a drive device 5, a main rope 8, and a tension wheel 9.

Therefore, the range in which the force 2 can ascend and descend in the hoistway 1 can be expanded, and the dimension of the hoistway 1 in the height direction can be further reduced by / J.
[0020] また、張り車 9は、各主ロープ 8に吊り下げられることにより、各主ロープ 8に張力を 与えるようになっているので、簡単な構成で各主ロープ 8に張力を与えることができ、 コストの低減を図ることができる。  [0020] Further, the tension wheel 9 is adapted to apply tension to each main rope 8 by being suspended from each main rope 8, so that tension can be applied to each main rope 8 with a simple configuration. And cost can be reduced.
[0021] また、各主ロープ 8の外周部には、高摩擦材が設けられているので、各主ロープ 8と 駆動シーブ 7との間の摩擦力を確保することができ、各主ロープ 8と駆動シーブ 7との 間の滑りを防止することができる。  [0021] Further, since a high friction material is provided on the outer peripheral portion of each main rope 8, a frictional force between each main rope 8 and the drive sheave 7 can be secured.

図 7は、この発明の実施の形態 5によるエレベータ装置を示す側面図である。図に おいて、昇降路 1内の上部には、返し車 51が設けられている。返し車 51は、かごガイ ドレールに対して固定された水平軸を中心に回転可能になっている。  FIG. 7 is a side view showing an elevator apparatus according to Embodiment 5 of the present invention. In the figure, a return wheel 51 is provided in the upper part of the hoistway 1. The return wheel 51 is rotatable around a horizontal axis fixed to the car guide rail.
[0037] 昇降路 1内の下部には、駆動装置 5及び張り車 9が設けられている。張り車 9は、駆 動シーブ 7に対して間隔を置いて配置されている。また、張り車 9は、駆動シーブ 7の 上方に配置されている。駆動装置 5は、力ごガイドレールに対して固定されている。張 り車 9は、かごガイドレールに対して変位可能になっている。  [0037] A driving device 5 and a tensioning wheel 9 are provided in the lower part of the hoistway 1. The tension wheel 9 is arranged at a distance from the drive sheave 7. The tension wheel 9 is disposed above the drive sheave 7. The driving device 5 is fixed to the force guide rail. The tension wheel 9 can be displaced with respect to the car guide rail.
[0038] 各主ロープ 8は、第 1接続部 8aから、返し車 51、駆動シーブ 7、張り車 9及び駆動シ ーブ 7の順に巻き掛けられ、第 2接続部 8bに至っている。即ち、各主ロープ 8は、第 1 接続部 8aから、返し車 51を経て駆動シーブ 7に巻き掛けられた後に、張り車 9に巻き 掛けられ、駆動シーブ 7に再度巻き掛けられてから、第 2接続部 8bに至っている。  [0038] Each main rope 8 is wound from the first connecting portion 8a in the order of the return wheel 51, the driving sheave 7, the tensioning wheel 9, and the driving sheave 7, and reaches the second connecting portion 8b. That is, each main rope 8 is wound around the driving sheave 7 from the first connecting portion 8a through the return wheel 51, then wound around the tensioning wheel 9, and again wound around the driving sheave 7. 2 Leads to 8b.
[0039] 昇降路 1内には、各主ロープ 8に張力を与える方向へ張り車 9を付勢する付勢装置 52が設けられている。この例では、付勢装置 52は、張り車 9を駆動シーブ 7から離れ る方向へ付勢する弾性体である付勢ばね 53を有している。  In the hoistway 1, a biasing device 52 that biases the tensioning wheel 9 in a direction to apply tension to each main rope 8 is provided. In this example, the biasing device 52 includes a biasing spring 53 that is an elastic body that biases the tension wheel 9 in a direction away from the drive sheave 7.
[0040] なお、力ご 2を吊り下げて昇降路 1内を昇降させるための昇降機構 54は、駆動装置 5、主ロープ 8、張り車 9及び付勢装置 52を有している。昇降機構 54は、昇降路 1の 垂直投影面において、力ご 2の領域外に配置されている。他の構成は実施の形態 1 と同様である。 [0040] It should be noted that the elevating mechanism 54 for elevating the inside of the hoistway 1 by suspending the force 2 is a driving device. 5, main rope 8, tension wheel 9 and urging device 52. The lifting mechanism 54 is disposed outside the area of the force cage 2 on the vertical projection plane of the hoistway 1. Other configurations are the same as those in the first embodiment.
[0041] このようなエレベータ装置では、各主ロープ 8に張力を与える方向へ張り車 9が付勢 装置 52により付勢されているので、所定の付勢力で任意の方向へ張り車 9を付勢す ることができる。このことから、張り車 9が各主ロープ 8により吊り下げられるようにする ための返し車等を無くすことができ、また各主ロープ 8に与える張力を所定の大きさに 確保するためのおもりも無くすことができる。従って、部品点数を削減することができ、 コストの低減、及び昇降路 1の省スペース化を図ることができる。  [0041] In such an elevator apparatus, the tensioning wheel 9 is urged by the urging device 52 in the direction in which the tension is applied to each main rope 8, and therefore the tensioning wheel 9 is attached in any direction with a predetermined urging force. It can be supported. From this, it is possible to eliminate a return wheel or the like for allowing the tension wheel 9 to be suspended by each main rope 8, and also to provide a weight for securing the tension applied to each main rope 8 to a predetermined magnitude. It can be lost. Therefore, the number of parts can be reduced, the cost can be reduced, and the space of the hoistway 1 can be saved.
[0042] また、各主ロープ 8は、第 1接続部 8aから、返し車 51を経て駆動シーブ 7に卷き掛 けられた後に、張り車 9に巻き掛けられ、駆動シーブ 7に再度巻き掛けられてから、第 2接続部 8bに至って 、るので、各主ロープ 8の曲げ方向が常に同一方向になるよう に各主ロープ 8を昇降路 1内に設けることができる。即ち、各主ロープ 8の逆曲げの発 生を防止することができる。このことから、各主ロープ 8の長寿命化を図ることができる  [0042] Each main rope 8 is hooked around the driving sheave 7 from the first connecting portion 8a via the return wheel 51, and then wound around the tensioning wheel 9 and again around the driving sheave 7. Since the second connecting portion 8b is reached, the main ropes 8 can be provided in the hoistway 1 so that the bending directions of the main ropes 8 are always the same. That is, the occurrence of reverse bending of each main rope 8 can be prevented. From this, the life of each main rope 8 can be extended.
[0043] また、各主ロープ 8は、駆動シーブ 7に巻き掛けられた後に張り車 9に巻き掛けられ 、駆動シーブ 7に再度巻き掛けられているので、各主ロープ 8の駆動シーブ 7に対す る巻き付け角を増大させることができ、各主ロープ 8の駆動シーブ 7に対する滑りの発 生の防止を図ることができる。 [0043] Since each main rope 8 is wound around the driving sheave 7 and then wound around the tensioning wheel 9, it is wound around the driving sheave 7 again. The winding angle of the main rope 8 can be increased, and slippage of the main rope 8 with respect to the drive sheave 7 can be prevented.
[0044] なお、上記の例では、駆動装置 5及び張り車 9が昇降路 1内の下部に配置され、返 し車 51が昇降路 1内の上部に配置されて 、る力 昇降路 1内の下部に返し車 51を配 置し、昇降路 1内の上部に駆動装置 5及び張り車 9を配置してもよい。この場合、張り 車 9は、駆動シーブ 7の下方に配置される。また、各主ロープ 8は、第 1接続部 8aから 、駆動シーブ 7、張り車 9、駆動シーブ 7及び返し車 51の順に巻き掛けられ、第 2接続 部 8bに至るように、昇降路 1内に設けられる。  In the above example, the driving device 5 and the tensioning wheel 9 are arranged in the lower part in the hoistway 1, and the return wheel 51 is arranged in the upper part in the hoistway 1.

The drive sheaves 7 are rotated in synchronization with each other by the drive of the drive devices 5. Thereby, the main ropes 8 in the elevating mechanisms 63 and 64 are circulated and moved in synchronization with each other. As a result, the force 2 is moved up and down in the hoistway 1. At this time, since the main ropes 8 are circulated and moved in synchronization with each other, the force 2 is raised and lowered stably.
