Description

本発明は、昇降路内のガイドレールに沿って乗りかごと釣合いおもりが移動するエレベーター装置に関するものである。   The present invention relates to an elevator apparatus in which a car and a counterweight move along a guide rail in a hoistway.

従来から、乗りかご及び釣合いおもりを、３：１ローピングで吊り下げたエレベーター装置が提案されている。例えば、下記特許文献１には、従来の２：１ローピングのエレベーター装置に対して、ロープに作用する張力が２／３となり、駆動装置に作用する巻き上げトルクが低減され、結果的に駆動装置を小型化できることが記載されている。   Conventionally, an elevator apparatus has been proposed in which a car and a counterweight are suspended by 3: 1 roping. For example, in Patent Document 1 below, the tension acting on the rope is 2/3 compared to the conventional 2: 1 roping elevator device, the winding torque acting on the driving device is reduced, and as a result, the driving device is It is described that the size can be reduced.

特開２００４−８３２３１号（段落番号００２３，第１図等）Japanese Patent Laid-Open No. 2004-83231 (paragraph number 0023, FIG. 1 etc.)

しかしながら、上記特許文献１に記載されたエレベーター装置では、駆動装置の鉛直投影が、乗りかごの鉛直投影と重なるように配置されている。このため、乗りかごと接触しない高い場所に巻上機を配置する必要があり、結果的に昇降路の高さ方向を省スペース化できなかった。   However, in the elevator apparatus described in Patent Document 1, the vertical projection of the driving device is arranged so as to overlap the vertical projection of the car. For this reason, it is necessary to arrange the hoisting machine at a high place where it does not come into contact with the carriage, and as a result, the height direction of the hoistway cannot be saved.

本発明の目的は、昇降路の高さ方向を省スペース化したエレベーター装置を提供することである。   An object of the present invention is to provide an elevator apparatus that saves space in the height direction of a hoistway.

上記目的を達成するために、本発明は、昇降路内でロープにより吊られた乗りかごと釣合いおもりが巻上機により駆動されるエレベーター装置において、前記乗りかごの上部に設けられた吊り車と、前記乗りかごの上部又は側部に設けられた綱止め部と、前記釣合いおもりの上部に設けられた吊り車と、前記釣合いおもりの上部に設けられた綱止め部を備え、前記巻上機の鉛直投影が、前記乗りかごの鉛直投影と前記昇降路壁の鉛直投影の間に位置するようにした。   In order to achieve the above object, the present invention provides an elevator apparatus in which a car and a counterweight suspended by a rope in a hoistway are driven by a hoist, and a suspension car provided at an upper part of the car. A hoist provided at the upper part or side part of the car, a suspension car provided at the upper part of the counterweight, and a leash part provided at the upper part of the counterweight, The vertical projection is located between the vertical projection of the car and the vertical projection of the hoistway wall.

本発明によれば、昇降路の高さ方向を省スペース化したエレベーター装置を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the elevator apparatus which saved space in the height direction of the hoistway can be provided.

以下、本発明の実施例について、図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は、本発明の第１の実施例を示すエレベーター装置のロープ５の掛け方を示す図であり、図２は、本実施例のエレベーターにおける昇降路の平面断面図である。本実施例のエレベーター装置では、乗りかご１が、乗りかごガイドレール１６ａ，１６ｂに沿って昇降し、釣合いおもり１２が、釣合いおもりガイドレール１７ａ，１７ｂに沿って昇降するように構成されている。また、乗りかご１と釣合いおもり１２は、ロープ５により吊られ、巻上機１０により駆動される。   FIG. 1 is a diagram showing how to hang a rope 5 of an elevator apparatus according to a first embodiment of the present invention, and FIG. 2 is a plan sectional view of a hoistway in the elevator according to the present embodiment. In the elevator apparatus of this embodiment, the car 1 is moved up and down along the car guide rails 16a and 16b, and the counterweight 12 is moved up and down along the counterweight guide rails 17a and 17b. The car 1 and the counterweight 12 are suspended by the rope 5 and driven by the hoisting machine 10.

更に、乗りかご１の天井部には、かご上枠３が設置され、このかご上枠３に、綱止め部４及び吊り車８が取付けられている。一方、釣合いおもり１２の上部にも、綱止め部１５及び吊り車１３が取付けられている。尚、綱止め部４，１５は、ロープ５の伸びを吸収する機能を有している。   Further, a car upper frame 3 is installed on the ceiling portion of the car 1, and a rope stopper 4 and a suspension car 8 are attached to the car upper frame 3. On the other hand, on the upper part of the counterweight 12, a rope stopper 15 and a suspension wheel 13 are attached. The rope stoppers 4 and 15 have a function of absorbing the elongation of the rope 5.

そして、昇降路の上部には、互いの鉛直投影が略平行な２つの返し車からなる第１の返し車７ａ及び７ｂと、互いの鉛直投影が略平行な２つの返し車からなる第２返し車９ａ及び９ｂと、第３返し車１４が設置されている。ここで、第１の返し車７ａ，７ｂ、吊り車８及び巻上機１０の駆動シーブ１１の鉛直投影と、第３の返し車１４の鉛直投影とは、互いに略垂直になるように配置されている。また、第２の返し車９ａ及び９ｂの鉛直投影は、第１の返し車７ａ等の鉛直投影に対して傾斜し、第３の返し車１４の鉛直投影に対して傾斜するように配置されている。尚、いずれの返し車も乗りかご１の天井部よりも上方にある。   And in the upper part of the hoistway, the first return wheels 7a and 7b composed of two return wheels whose vertical projections are substantially parallel to each other, and the second return wheel consisting of two return wheels whose vertical projections are substantially parallel to each other. Cars 9a and 9b and a third return wheel 14 are installed. Here, the vertical projection of the drive sheave 11 of the first return wheels 7a and 7b, the suspension wheel 8 and the hoisting machine 10 and the vertical projection of the third return wheel 14 are arranged so as to be substantially perpendicular to each other. ing. Further, the vertical projections of the second return wheels 9a and 9b are arranged so as to be inclined with respect to the vertical projection of the first return wheel 7a and the like and inclined with respect to the vertical projection of the third return wheel 14a. Yes. Note that any return wheel is above the ceiling of the car 1.

次に、本実施例のエレベーター装置におけるロープ５の掛け方について説明する。基本的には、本実施例のエレベーター装置は、綱止め部４，１５と、吊り車８，１３を利用して、乗りかご１と釣合いおもり１２を吊る、３：１ローピング方式を採用している。具体的には図１に示す通りであり、まず、ロープ５の一端が、乗りかご１の上部の綱止め部４に固定され、この綱止め部４から上方へ伸び第１の返し車７ａから略水平に伸びてもう一つの第１の返し車７ｂに至り、この第１の返し車７ｂによって下方へ方向転換される。更に、このロープ５は、乗りかご１の上部の吊り車８を介して上方へ方向転換し、第２の返し車９ａの上部に巻き掛けられた後、もう一つの第２の返し車９ｂの下部に巻き掛けられ、その後、巻上機１０の駆動シーブ１１に巻き掛けられて下方へ方向転換する。更に、このロープ５は、釣合いおもり１２の上部の吊り車１３を介して上方へ方向転換され、第３の返し車１４を介して釣合いおもり１２の上部の綱止め部１５に至り、この綱止め部１５にロープ５の他端が固定される。   Next, how to hang the rope 5 in the elevator apparatus of the present embodiment will be described. Basically, the elevator apparatus according to the present embodiment employs a 3: 1 roping method that suspends the car 1 and the counterweight 12 using the clasps 4 and 15 and the suspension cars 8 and 13. Yes. Specifically, as shown in FIG. 1, first, one end of the rope 5 is fixed to the rope stopper 4 on the upper portion of the car 1, and extends upward from the rope stopper 4 and from the first return wheel 7 a. The first return wheel 7b extends substantially horizontally and is turned downward by the first return wheel 7b. Further, the rope 5 changes its direction upward via the suspension wheel 8 at the top of the car 1, and is wound around the upper part of the second return wheel 9a, and then the other second return wheel 9b. It winds around the lower part, and then winds around the drive sheave 11 of the hoisting machine 10 and turns downward. Further, the rope 5 is turned upward via a suspension wheel 13 at the upper part of the counterweight 12, and reaches a rope stopper 15 at the upper part of the counterweight 12 via a third return wheel 14. The other end of the rope 5 is fixed to the portion 15.

また、巻上機１０は、その鉛直投影が、乗りかご１の鉛直投影と昇降路壁１８の鉛直投影の間に位置するように設けられている。したがって、巻上機１０と乗りかご１との接触を避けるための空間を高さ方向に設ける必要がなくなり、昇降路の高さ方向を省スペース化できる。また、巻上機１０は胴長であるため、その駆動シーブ１１の鉛直投影が乗りかご１の奥行方向と略垂直であっても、乗りかご１の左側部の限られた空間内に巻上機１０を配置できる。ここで、胴長の巻上機１０とは、巻上機１０の軸方向の長さの方が、巻上機１０の駆動シーブ１１の直径よりも大きいものをいう。また、乗りかご１の奥行方向とは、かごドア２と垂直な方向を意味し、乗りかご１の左側部とは、エレベーターの乗場側から見て乗りかご１の左の部分を意味する。   The hoisting machine 10 is provided such that its vertical projection is located between the vertical projection of the car 1 and the vertical projection of the hoistway wall 18. Therefore, it is not necessary to provide a space for avoiding the contact between the hoisting machine 10 and the car 1 in the height direction, and the height direction of the hoistway can be saved. Further, since the hoisting machine 10 has a trunk length, even if the vertical projection of the driving sheave 11 is substantially perpendicular to the depth direction of the car 1, the hoisting machine 10 is hoisted in a limited space on the left side of the car 1. The machine 10 can be arranged. Here, the hoisting machine 10 of the trunk length means that the axial length of the hoisting machine 10 is larger than the diameter of the drive sheave 11 of the hoisting machine 10. Further, the depth direction of the car 1 means a direction perpendicular to the car door 2, and the left side of the car 1 means the left part of the car 1 when viewed from the elevator landing side.

更に、本実施例では、釣合いおもり１２も、乗りかご１の左側部に配置されており、この釣合いおもり１２の上方に、胴長の巻上機１０が位置している。つまり、巻上機１０の鉛直投影と釣合いおもり１２の鉛直投影とが重なっているので、昇降路面積の省スペース化が可能となる。また、巻上機１０の重心の鉛直投影は、釣合いおもり１２の一対のガイドレール１７ａ，１７ｂの鉛直投影の間付近に位置しているため、図示しない支持部材を介して、巻上機１０の荷重を、釣合いおもり１２の一対のガイドレール１７ａ，１７ｂで支持できる。   Further, in this embodiment, the counterweight 12 is also arranged on the left side of the car 1, and the trunk hoist 10 is located above the counterweight 12. That is, since the vertical projection of the hoisting machine 10 and the vertical projection of the counterweight 12 overlap each other, it is possible to save the hoistway area. Further, since the vertical projection of the center of gravity of the hoisting machine 10 is located in the vicinity between the vertical projections of the pair of guide rails 17a and 17b of the counterweight 12, the hoisting machine 10 is provided with a support member (not shown). The load can be supported by the pair of guide rails 17 a and 17 b of the counterweight 12.

上述のような本実施例によれば、３：１ローピングであるため、懸垂荷重が３つのロープに分散され、返し車への懸垂荷重が低減され、また、巻上機１０のトルクが小さくて済む。つまり、エレベーター装置の強度部材や巻上機１０の小型化が可能となるので、昇降路を省スペース化する効果が期待できる。   According to the present embodiment as described above, because of 3: 1 roping, the suspension load is distributed to the three ropes, the suspension load to the return wheel is reduced, and the torque of the hoisting machine 10 is small. That's it. That is, since the strength member of the elevator apparatus and the hoisting machine 10 can be downsized, an effect of saving the hoistway space can be expected.

また、第２の返し車９ａ，９ｂを設けることにより、巻上機１０の位置が調整できる。具体的には、乗りかご１の鉛直投影と昇降路壁１８の鉛直投影の間に、巻上機１０の鉛直投影が位置するように、巻上機１０を配置することができる。また、巻上機１０の鉛直投影が乗りかご１の鉛直投影と重ならないため、より上方へ乗りかご１を移動させることが可能となり、結果として昇降路の上部を省スペース化できる。   Moreover, the position of the hoisting machine 10 can be adjusted by providing the second return wheels 9a and 9b. Specifically, the hoisting machine 10 can be arranged so that the vertical projection of the hoisting machine 10 is positioned between the vertical projection of the car 1 and the vertical projection of the hoistway wall 18. Further, since the vertical projection of the hoisting machine 10 does not overlap with the vertical projection of the car 1, the car 1 can be moved further upward, and as a result, the space above the hoistway can be saved.

更に、本実施例では、釣合いおもり１２及び巻上機１０を、乗りかご１の左側部に配置したので、乗りかご１の奥行方向の寸法を小さくしたくない場合に有効である。   Furthermore, in this embodiment, the counterweight 12 and the hoisting machine 10 are arranged on the left side of the car 1, so that it is effective when it is not desired to reduce the depth dimension of the car 1.

図３は、本発明の第２の実施例を示すエレベーター装置のロープ５の掛け方を示す図であり、図４は、本実施例のエレベーターにおける昇降路の平面断面図である。本実施例のエレベーター装置は、基本的には第１の実施例と同じ構成であるので、第１の実施例と異なる点に重点を置いて説明する。   FIG. 3 is a diagram showing how the rope 5 of the elevator apparatus according to the second embodiment of the present invention is hung, and FIG. 4 is a plan sectional view of a hoistway in the elevator according to the present embodiment. Since the elevator apparatus of the present embodiment basically has the same configuration as that of the first embodiment, the description will be given with an emphasis on differences from the first embodiment.

まず、本実施例では、乗りかご１の綱止め部４が、乗りかご１の側部の下方に設けられており、この綱止め部４に固定されたロープ５が、乗りかご１の側部に沿って上方へ伸び、乗りかご１の上部に取付けられたロープガイド装置６を介して、第１の返し車７ａに至っている。   First, in the present embodiment, the leash 4 of the car 1 is provided below the side of the car 1, and the rope 5 fixed to the leash 4 is connected to the side of the car 1. And reaches the first return wheel 7a via a rope guide device 6 attached to the upper part of the car 1.

また、第２の返し車９ａ，９ｂの鉛直投影が、第１の返し車７ａ，７ｂ及び吊り車８の鉛直投影と、略垂直に配置されている。そして、巻上機１０及び釣合いおもり１２が、乗りかご１の背部に配置されている。ここで、乗りかご１の背部とは、乗場側から見て乗りかご１の後方の部分を意味する。   Further, the vertical projections of the second return wheels 9a and 9b are arranged substantially perpendicular to the vertical projections of the first return wheels 7a and 7b and the suspension vehicle 8. A hoisting machine 10 and a counterweight 12 are arranged on the back of the car 1. Here, the back part of the car 1 means a rear part of the car 1 when viewed from the landing side.

また、巻上機１０が胴長であるため、その駆動シーブ１１の鉛直投影が乗りかご１の奥行方向と略平行であっても、乗りかご１の背部の限られた空間内に巻上機１０を配置できる。   Further, since the hoisting machine 10 has a trunk length, even if the vertical projection of the drive sheave 11 is substantially parallel to the depth direction of the car 1, the hoisting machine is in a limited space at the back of the car 1. 10 can be arranged.

本実施例によれば、基本的に、第１の実施例と同様の効果が達成できる。更に、本実施例では、釣合いおもり１２及び巻上機１０を、乗りかご１の背部に配置したので、乗りかご１の左右方向の寸法を小さくしたくない場合に有効である。また、綱止め部４が乗りかご１の下部近傍にあるため、ロープ５の経年伸びを吸収するための調整作業が、昇降路の最下部であるピットで容易に行えるようになり、保守作業の向上につながる。   According to the present embodiment, basically the same effect as that of the first embodiment can be achieved. Furthermore, in this embodiment, the counterweight 12 and the hoisting machine 10 are arranged on the back of the car 1, so that it is effective when it is not desired to reduce the horizontal dimension of the car 1. In addition, since the rope stop 4 is near the lower part of the car 1, the adjustment work for absorbing the secular growth of the rope 5 can be easily performed at the pit at the lowest part of the hoistway. It leads to improvement.

図５は、本発明の第３の実施例を示すエレベーター装置のロープ５の掛け方を示す図であり、図６は、本実施例のエレベーターにおける昇降路の平面断面図である。本実施例のエレベーター装置は、基本的には第２の実施例と同じ構成であるので、第２の実施例と異なる点に重点を置いて説明する。   FIG. 5 is a diagram illustrating how the rope 5 of the elevator apparatus according to the third embodiment of the present invention is hung, and FIG. 6 is a plan sectional view of a hoistway in the elevator according to the present embodiment. Since the elevator apparatus of the present embodiment has basically the same configuration as that of the second embodiment, the following description will be given with an emphasis on differences from the second embodiment.

まず、本実施例では、第２の返し車が３つの返し車９ａ，９ｂ，９ｃからなり、そのうち、第２の返し車９ａと９ｂは、その鉛直投影が互いに略平行である。ここで、第１の返し車７ａ，７ｂ及び吊り車８の鉛直投影と、第３の返し車１４，第２の返し車９ｃ，巻上機１０の駆動シーブ１１及び吊り車１３の鉛直投影とは、互いに略垂直になるように配置されている。また、第２の返し車９ａ及び９ｂの鉛直投影は、第１の返し車７ａ等の鉛直投影に対して傾斜し、第３の返し車１４等の鉛直投影に対して傾斜するように配置されている。   First, in this embodiment, the second return wheel is composed of three return wheels 9a, 9b, 9c, and the vertical projections of the second return wheels 9a and 9b are substantially parallel to each other. Here, vertical projections of the first return wheels 7a and 7b and the suspension wheel 8, and vertical projections of the third return wheel 14, the second return wheel 9c, the driving sheave 11 of the hoisting machine 10, and the suspension wheel 13 Are arranged so as to be substantially perpendicular to each other. Further, the vertical projections of the second return wheels 9a and 9b are arranged so as to be inclined with respect to the vertical projection of the first return wheel 7a and the like and inclined with respect to the vertical projection of the third return wheel 14 and the like. ing.

次に、本実施例のエレベーター装置におけるロープ５の掛け方について説明する。まず、ロープ５の一端が、乗りかご１の側部の下方に設けられた綱止め部４に固定され、この綱止め部から乗りかご１の側部に沿って上方へ伸び、乗りかご１の上部に取付けられたロープガイド装置６を介して、第１の返し車７ａに至る。そして、このロープ５は、略水平に伸びてもう一つの第１の返し車７ｂによって下方へ方向転換された後、吊り車８を介して上方へ方向転換され、第２の返し車９ａの上部から略水平に伸びて第２の返し車９ｂの上部に達する。更に、ロープ５は、この第２の返し車９ｂで下方へ方向転換された後、第２の返し車９ｃを介して上方へ方向転換され、巻上機１０の駆動シーブ１１に巻き掛けられて下方へ方向転換する。そして、このロープ５は、釣合いおもり１２の上部の吊り車
１３を介して上方へ方向転換され、第３の返し車１４を介して釣合いおもり１２の上部の綱止め部１５に至り、この綱止め部１５にロープ５の他端が固定される。 Next, how to hang the rope 5 in the elevator apparatus of the present embodiment will be described. First, one end of the rope 5 is fixed to a rope stop 4 provided below the side of the car 1 and extends upward along the side of the car 1 from the rope stop. It reaches the first return wheel 7a via the rope guide device 6 attached to the upper part. The rope 5 extends substantially horizontally and is turned downward by another first return wheel 7b, and is then turned upward via the suspension wheel 8 to be connected to the upper portion of the second return wheel 9a. Extends substantially horizontally and reaches the top of the second return wheel 9b. Further, the rope 5 is turned downward by the second return wheel 9b, then turned upward via the second return wheel 9c, and is wound around the drive sheave 11 of the hoisting machine 10. Turn down. Then, the rope 5 is turned upward through a suspension wheel 13 at the upper part of the counterweight 12, and reaches a rope stopper 15 at the upper part of the counterweight 12 via a third return wheel 14. The other end of the rope 5 is fixed to the portion 15.

また、巻上機１０は薄型であって、その駆動シーブ１１の鉛直投影が、乗りかご１の奥行方向と略平行になるように配置されているため、乗りかご１の左側部の限られた空間内に巻上機１０を配置できる。ここで、薄型の巻上機１０とは、巻上機１０の軸方向の長さの方が、巻上機１０の駆動シーブ１１の直径よりも小さいものをいう。更に、本実施例では、釣合いおもり１２も、乗りかご１の左側部に配置されており、この釣合いおもり１２の上方に、薄型の巻上機１０が位置している。   Further, the hoisting machine 10 is thin, and the vertical projection of the drive sheave 11 is arranged so as to be substantially parallel to the depth direction of the car 1, so that the left side portion of the car 1 is limited. The hoisting machine 10 can be arranged in the space. Here, the thin hoisting machine 10 refers to a machine in which the axial length of the hoisting machine 10 is smaller than the diameter of the drive sheave 11 of the hoisting machine 10. Further, in this embodiment, the counterweight 12 is also arranged on the left side of the car 1, and a thin hoisting machine 10 is located above the counterweight 12.

本実施例によれば、基本的に、第２の実施例と同様の効果が達成できる。更に、本実施例では、巻上機１０の重心の鉛直投影が、釣合いおもり１２の重心の鉛直投影と略一致しているため、巻上機１０の荷重を釣合いおもり１２の一対のガイドレール１７ａ，１７ｂで容易に支持できる。また、第２の返し車９ｃを追加することによって、上述のような薄型の巻上機１０が設置でき、昇降路面積の省スペース化が可能となる。そして、釣合いおもり１２及び巻上機１０を、乗りかご１の左側部に配置したので、乗りかご１の奥行方向の寸法を小さくしたくない場合に有効である。   According to the present embodiment, basically the same effect as that of the second embodiment can be achieved. Furthermore, in the present embodiment, the vertical projection of the center of gravity of the hoisting machine 10 is substantially coincident with the vertical projection of the center of gravity of the counterweight 12, so that the load of the hoisting machine 10 is paired with the pair of guide rails 17 a of the counterweight 12. 17b can be easily supported. Further, by adding the second return wheel 9c, the thin hoisting machine 10 as described above can be installed, and the hoistway area can be saved. Since the counterweight 12 and the hoisting machine 10 are disposed on the left side of the car 1, it is effective when it is not desired to reduce the dimension of the car 1 in the depth direction.

図７は、本発明の第４の実施例を示すエレベーター装置のロープ５の掛け方を示す図であり、図８は、本実施例のエレベーターにおける昇降路の平面断面図である。本実施例のエレベーター装置は、基本的には第３の実施例と同じ構成であるので、第３の実施例と異なる点に重点を置いて説明する。   FIG. 7 is a diagram showing how the rope 5 of the elevator apparatus according to the fourth embodiment of the present invention is hung, and FIG. 8 is a plan sectional view of a hoistway in the elevator according to the present embodiment. Since the elevator apparatus of the present embodiment basically has the same configuration as that of the third embodiment, the description will be given with an emphasis on differences from the third embodiment.

本実施例では、第１の返し車７ａ，７ｂ及び吊り車８の鉛直投影と、第３の返し車１４，第２の返し車９ｃ，巻上機１０の駆動シーブ１１及び吊り車１３の鉛直投影とは、互いに略平行になるように配置されている。   In this embodiment, the vertical projections of the first return wheels 7a and 7b and the suspension wheel 8, the vertical directions of the third return wheel 14, the second return wheel 9c, the drive sheave 11 of the hoisting machine 10 and the suspension wheel 13 are shown. The projections are arranged so as to be substantially parallel to each other.

また、巻上機１０は薄型であって、その駆動シーブ１１の鉛直投影が、乗りかご１の奥行方向と略垂直になるように配置されているため、乗りかご１の背部の限られた空間内に巻上機１０を配置できる。   Further, the hoisting machine 10 is thin, and the vertical projection of the drive sheave 11 is arranged so as to be substantially perpendicular to the depth direction of the car 1, so that the space limited in the back part of the car 1 is limited. The hoisting machine 10 can be arranged inside.

更に、本実施例では、釣合いおもり１２も、乗りかご１の背部に配置されており、この釣合いおもり１２の上方に、薄型の巻上機１０が位置している。   Furthermore, in the present embodiment, the counterweight 12 is also disposed on the back of the car 1, and a thin hoisting machine 10 is located above the counterweight 12.

図９は、本発明の第５の実施例を示すエレベーター装置のロープ５の掛け方を示す図であり、図１０は、本実施例のエレベーターにおける昇降路の平面断面図である。本実施例のエレベーター装置は、第２の実施例に近い構成であるので、第２の実施例と異なる点に重点を置いて説明する。   FIG. 9 is a diagram showing how the rope 5 of the elevator apparatus according to the fifth embodiment of the present invention is hung, and FIG. 10 is a plan sectional view of a hoistway in the elevator according to the present embodiment. Since the elevator apparatus of the present embodiment has a configuration close to that of the second embodiment, the following description will be given with an emphasis on differences from the second embodiment.

本実施例では、乗りかご１の上部に２つの吊り車８，８ａが設けられる一方、釣合いおもり１２の上部に吊り車１３，１３ａが設けられており、乗りかご１と釣合いおもり１２を４：１ローピングで吊る方式が採用されている。   In this embodiment, two suspension vehicles 8 and 8a are provided on the upper portion of the car 1, while suspension vehicles 13 and 13a are provided on the upper portion of the counterweight 12, so that the car 1 and the counterweight 12 are arranged at 4: A method of hanging by one roping is adopted.

具体的なロープ５の掛け方は、図９に示す通りであり、まず、ロープ５の一端が、昇降路の上部の綱止め部４に固定されている。そして、このロープ５は、この綱止め部４から下方へ伸び乗りかご１の第１の吊り車８を介して方向転換されて上方へ伸び、第１の返し車７ａから水平に伸び第１の返し車７ｂにより方向転換されて下方へ伸びる。更に、このロープ５は、乗りかご１の第２の吊り車８ａを介して方向転換されて上方へ伸び、第２返し車９ａの上部に巻き掛けられた後、第２の返し車９ｂの下部に巻き掛けられ、その後、巻上機１０の駆動シーブ１１に巻き掛けられて下方へ方向転換する。次に、このロープ５は、釣合いおもり１２の第１の吊り車１３を介して上方へ方向転換された後、第３の返し車１４を介して下方へ方向転換され、釣合いおもり１２の第２の吊り車１３ａを介して上方へ方向転換される。そして、このロープ５は、昇降路の上部の綱止め部１５に至り、この綱止め部１５でロープ５の他端が固定される。   A specific method of hanging the rope 5 is as shown in FIG. 9. First, one end of the rope 5 is fixed to the rope stopper 4 at the upper part of the hoistway. The rope 5 extends downward from the rope stop 4 and is redirected via the first suspension wheel 8 of the car 1, extending upward, and extending horizontally from the first return wheel 7a. The direction is changed by the return wheel 7b and extends downward. Further, the rope 5 is changed in direction through the second suspension wheel 8a of the car 1, extends upward, is wound around the upper part of the second return wheel 9a, and then the lower part of the second return wheel 9b. Then, it is wound around the drive sheave 11 of the hoisting machine 10 and turns downward. Next, the rope 5 is turned upward through the first suspension wheel 13 of the counterweight 12 and then turned downward through the third return wheel 14, so that the second weight of the counterweight 12 is changed. The direction is changed upward through the suspension wheel 13a. And this rope 5 reaches the rope stop 15 of the upper part of a hoistway, and the other end of the rope 5 is fixed by this rope stop 15.

本実施例によれば、第２の実施例とほぼ同様の効果が達成できる。更に、本実施例では、乗りかご１及び釣合いおもり１２を４：１ローピングで吊っているため、第２の実施例などの３：１ローピングの場合と比べて、エレベーター装置の強度部材や巻上機１０をより小型化できるので、昇降路をより省スペース化することが可能である。   According to this embodiment, substantially the same effect as that of the second embodiment can be achieved. Further, in the present embodiment, the car 1 and the counterweight 12 are hung by 4: 1 roping, so that the strength member and hoisting of the elevator apparatus are higher than in the case of 3: 1 roping in the second embodiment. Since the machine 10 can be further downsized, the hoistway can be more space-saving.

尚、本実施例では、釣合いおもり１２及び巻上機１０を、乗りかご１の背部に配置したが、第２の返し車９ａ，９ｂの配置を変更することにより、釣合いおもり１２等を、乗りかご１の側部に配置することも可能である。つまり、上述の実施例の如く、第２返し車の配置を工夫することによって、昇降路の形状や乗りかご１の形状に応じて、側部または背部の任意の位置に巻上機１０及び釣合いおもり１２を配置し、設置効率の良い機器のレイアウトが選択できる。また、本実施例では、胴長の巻上機１０を用いたが、第２の返し車９ｃを追加することにより、薄型の巻上機１０を用いることも可能である。   In this embodiment, the counterweight 12 and the hoisting machine 10 are arranged on the back of the car 1. However, by changing the arrangement of the second return wheels 9a and 9b, the counterweight 12 and the like are It can also be arranged on the side of the car 1. In other words, the hoisting machine 10 and the balance can be placed at any position on the side or back according to the shape of the hoistway or the shape of the car 1 by devising the arrangement of the second return wheel as in the above-described embodiment. A weight 12 can be arranged to select a layout of equipment with good installation efficiency. Further, in the present embodiment, the hoisting machine 10 having a trunk length is used, but it is also possible to use a thin hoisting machine 10 by adding a second return wheel 9c.
