The structure is disposed on the side opposite to the car relative to the main movable body and the secondary movable body, and is connected to the main movable body and the secondary movable body. The main movable body is tilted by the wind pressure when the car descends, such that the edge located on the outer side of the car is higher than the edge located on the central side of the car. The secondary movable body is linked with the main movable body through the connecting body when the car descends, thereby tilting by the way that the edge located on the outer side of the car is lower than the edge located on the central side of the car.

[0034] The embodiments will be described with reference to the accompanying drawings. Furthermore, in each drawing, the same or equivalent parts are labeled with the same reference numerals. Repetitive descriptions of these parts are appropriately simplified or even omitted.

[0035] Implementation Method 1

[0036] Figure 1 This is a side view of a key part of an elevator that uses the rectifier system of the elevator in Embodiment 1. Figure 2 This is a top view of a key part of an elevator that uses the rectifier system of the elevator in Embodiment 1.

[0037] exist Figure 1 and Figure 2 In the elevator, the traction machine (not shown) is located in the shaft or machine room. The main rope 1 is wound around the traction machine.

[0038] The car 2 is rectangular in shape. The car 2 is located inside the hoistway. A car frame 3 surrounds the car 2 and supports it. Specifically, the car frame 3 includes an upper frame 4, a lower frame 5, and a pair of longitudinal columns 6. The upper frame 4 is positioned above the car 2 and is connected to one side of the main rope 1. The lower frame 5 is positioned below the car 2. One of the pair of longitudinal columns is positioned on the outer side of one side of the car 2. One of the pair of longitudinal columns connects one side of the upper frame 4 to one side of the lower frame 5. The other of the pair of longitudinal columns is positioned on the outer side of the other side of the car 2 and connects the other side of the upper frame 4 to the other side of the lower frame 5.

[0039] Door 7 is rectangular. Door 7 is located on the landing side of car 2 (not shown). Door 7 is configured to allow opening and closing of the entrance / exit of car 2. A baffle 8 is installed directly below door 7 on the lower edge of car 2. The baffle 8 is installed to prevent users from falling.

[0040] The counterweight 9 is rectangular in shape. It is located inside the hoistway. The counterweight 9 is positioned opposite the landing side (not shown) to the car 2. The upper part of the counterweight 9 is connected to the other side of the main rope 1.

[0041] For example, a rectification system is provided above the car 2. The rectification system is provided to reduce noise inside the car 2. The rectification system includes an upper rectification device 10. The upper rectification device 10 is provided above the car 2. The upper rectification device 10 includes an upper rectifier 11, an upper movable body 12, an upper rotating shaft 13, and an upper force-applying body 14.

[0042] The upper fairing 11 is rectangular. The upper fairing 11 is disposed above the car 2 and separate from the car 2. The upper fairing 11 is spaced apart from the upper surface of the car 2. For example, the upper fairing 11 is fixed to the upper frame 4. For example, the upper fairing 11 is fixed to a structure other than the upper frame 4. An opening 11a is formed in the center of the upper fairing 11. The opening 11a is pierced by the main rope 1.

[0043] The upper movable body 12 is rectangular. The upper movable body 12 is adjacent to the edge of the upper fairing 11 on the side opposite to the deck.

[0044] The upper rotating shaft 13 supports the edge of the upper movable body 12 located on the central side of the car 2, allowing it to rotate freely.

[0045] The upper force-applying body 14 is disposed around the adjacent portions of the upper fairing 11 and the upper movable body 12. Specifically, the upper force-applying body 14 has an upper force-applying portion 14a and a lower force-applying portion 14b. The upper force-applying portion 14a is disposed directly above the adjacent portions of the upper fairing 11 and the upper movable body 12. The lower force-applying portion 14b is disposed directly below the adjacent portions of the upper fairing 11 and the upper movable body 12.

[0046] Next, use Figure 3 The operation of the rectifier system during the ascent of car 2 is explained.

[0047] Figure 3 This is a side view of a key part of an elevator that uses the rectifier system of the elevator in Embodiment 1.

[0048] exist Figure 3 In this configuration, if the traction machine rotates in one direction, the main rope 1 moves in tandem with the rotation of the traction machine. The car 2 rises in tandem with the movement of the main rope 1. The counterweight 9 descends in tandem with the movement of the main rope 1.

[0049] At this time, in the rectification system, the upper movable body 12 is subjected to wind pressure. Due to this wind pressure, the upper movable body 12 rotates around the upper rotation axis 13. As a result, the upper movable body 12 tilts such that its outer edge on the car 2 is lower than its central edge on the car 2. At this time, the rotation range of the upper movable body 12 is limited by the force-applying part 14b directly below the upper force-applying body 14.

[0050] Next, use Figure 4 The operation of the rectifier system during the descent of car 2 is explained.

[0051] Figure 4 This is a side view of a key part of an elevator that uses the rectifier system of the elevator in Embodiment 1.

[0052] exist Figure 4 If the traction machine rotates in another direction, the main rope 1 moves in tandem with the rotation of the traction machine. The car 2 descends in tandem with the movement of the main rope 1. The counterweight 9 ascends in tandem with the movement of the main rope 1.

[0053] At this time, in the rectification system, the upper movable body 12 is subjected to wind pressure. Due to this wind pressure, the upper movable body 12 rotates around the upper rotation axis 13. As a result, the upper movable body 12 tilts such that its outer edge on the car 2 is positioned higher than its central edge on the car 2. At this time, the rotation range of the upper movable body 12 is limited by the force-applying part 14a directly above the upper force-applying body 14.

[0054] According to Embodiment 1 described above, the upper fairing 11 is disposed above the car 2 and separate from the car 2. An upper movable body 12 is adjacent to the upper fairing 11. The edge of the upper movable body 12 located on the central side of the car 2 is supported for free rotation. When the car 2 rises, the upper movable body 12 tilts such that the edge located on the outer side of the car 2 is lower than the edge located on the central side of the car 2. When the car 2 descends, the upper movable body 12 tilts such that the edge located on the outer side of the car 2 is higher than the edge located on the central side of the car 2. Therefore, with a simple structure, noise inside the car 2 can be suppressed during car 2 ascent and descent.

[0055] In addition, such as Figure 3 and Figure 4 As shown, the upper movable body 12 shifts in the direction of mitigating wind pressure. In this case, turbulence in the airflow around the car 2 is suppressed. Therefore, the generation of wind noise caused by turbulent airflow around the car 2 can be suppressed. As a result, noise inside the car 2 can be suppressed.

[0056] In the upper part of the car 2 in Embodiment 1, the cross-sectional area of ​​the air passage changes relatively gradually. Therefore, it is possible to suppress the airflow from becoming too fast. As a result, it is possible to suppress noise inside the car 2.

[0057] Implementation Method 2

[0058] Figure 5 and Figure 6 This is a side view of a key part of an elevator that uses the rectifier system of the elevator in Embodiment 2. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0059] like Figure 5 and Figure 6 As shown, the rectification system of Embodiment 2 is a system in which a lower rectification device 15 is added to the rectification system of Embodiment 1.

[0060] The lower fairing 15 includes a lower fairing 16, a lower movable body 17, a lower rotating shaft 18, and a lower force-applying body 19. The lower fairing 16, lower movable body 17, lower rotating shaft 18, and lower force-applying body 19 have substantially the same functions as the upper fairing 11, upper movable body 12, upper rotating shaft 13, and upper force-applying body 14.

[0061] However, the lower fairing 16 is disposed separately from the car 2 below the car 2. For example, the lower fairing 16 is fixed to the lower frame 5. For example, the lower fairing 16 is fixed to a structure other than the lower frame 5.

[0062] The lower force-applying body 19 has an upper force-applying part 19a and a lower force-applying part 19b. The upper force-applying part 19a and the lower force-applying part 19b have functions that are substantially the same as those of the upper force-applying part 14a and the lower force-applying part 14b.

[0063] According to Embodiment 2 described above, the rectification system includes an upper rectification device 10 and a lower rectification device 15. Therefore, with a simple structure, noise inside the car 2 can be suppressed during the car 2's ascent and descent.

[0064] Furthermore, the upper movable body 12 and the lower movable body 17 are positioned on the horizontal projection plane closer to the inner side than the outer edge of the car 2. Therefore, when the car 2 rises, the lower movable body 17 suppresses noise generated by the collision of airflow separated from the car 2 with the lower fairing 16. When the car 2 descends, the upper movable body 12 suppresses noise generated by the collision of airflow separated from the car 2 with the upper fairing 11. As a result, noise inside the car 2 can be suppressed more reliably.

[0065] Alternatively, the upper rectifier 10 may be omitted. In this case, the same effect as in embodiment 1 can be obtained.

[0066] Implementation Method 3

[0067] Figure 7 and Figure 8 This is a side view of a key part of an elevator that uses the rectifier system of Embodiment 3. Furthermore, parts that are the same as or equivalent to those in Embodiment 2 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0068] like Figure 7 and Figure 8 As shown, the rectification system of Embodiment 3 is a system that adds an upper actuator 20 and a lower actuator 21 to the rectification system of Embodiment 2.

[0069] An upper actuator 20 is disposed around the upper rotating shaft 13. The upper actuator 20 causes the upper rotating shaft 13 to rotate in different amounts according to the lifting speed of the car 2. As a result, the upper movable body 12 tilts at different angles according to the lifting speed of the car 2.

[0070] The lower actuator 21 is disposed around the lower rotating shaft 18. The lower actuator 21 causes the rotation of the lower rotating shaft 18 to change according to the lifting speed of the car 2. As a result, the lower movable body 17 changes its tilt angle according to the lifting speed of the car 2.

[0071] According to Embodiment 3 described above, the rectifier system includes an upper actuator 20 and a lower actuator 21. Therefore, it can not only mitigate wind pressure, but also more reliably suppress airflow turbulence around the car 2 by actively controlling the airflow around the car 2.

[0072] At this time, the upper actuator 20 and the lower actuator 21 can also be linked. For example, the upper actuator 20 and the lower actuator 21 can be operated in such a way that the rotation angle of the upper movable body 12 is the same as the rotation angle of the lower movable body 17. In this case, the airflow around the entire car 2 can be optimized. As a result, noise inside the car 2 can be suppressed more reliably.

[0073] Alternatively, either the upper rectifier 10 or the lower rectifier 15 may be omitted. In this case, turbulence in the airflow around the car 2 can be suppressed by actively controlling the airflow around the car 2.

[0074] Implementation Method 4

[0075] Figure 9 This is a top view of a key part of an elevator that uses the rectifier system of the elevator in embodiment 4. Figure 10 This is a bottom view of a key part of an elevator that uses the rectifier system of Embodiment 4. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0076] like Figure 9 As shown, the upper movable body 12 of Embodiment 4 includes a plurality of upper movable plates 12a. The plurality of upper movable plates 12a are arranged horizontally parallel to the upper rotation axis 13. The edge of each of the plurality of upper movable plates 12a located at the center side of the car 2 is supported so that it can rotate freely relative to the upper rotation axis 13. When the car 2 rises, the edges of the plurality of upper movable plates 12a are tilted such that the edges located on the outer side of the car 2 are lower than the edges located on the center side of the car 2. When the car 2 descends, the edges of the plurality of upper movable plates 12a are tilted such that the edges located on the outer side of the car 2 are higher than the edges located on the center side of the car 2.

[0077] like Figure 10As shown, the lower movable body 17 of Embodiment 4 includes a plurality of lower movable plates 17a. The plurality of lower movable plates 17a are arranged horizontally parallel to the lower rotation axis 18. The edge of each of the plurality of lower movable plates 17a located at the center side of the car 2 is supported so that it can rotate freely relative to the lower rotation axis 18. When the car 2 rises, the edges of the plurality of lower movable plates 17a are tilted such that the edges located on the outer side of the car 2 are lower than the edges located on the center side of the car 2. When the car 2 descends, the edges of the plurality of lower movable plates 17a are tilted such that the edges located on the outer side of the car 2 are higher than the edges located on the center side of the car 2.

[0078] According to Embodiment 4 described above, a plurality of upper movable plates 12a are arranged in a direction parallel to the upper rotation axis 13. The plurality of upper movable plates 12a rotate about the same rotation axis. At this time, the plurality of upper movable plates 12a can be moved by a small amount of wind pressure. In this case, corresponding to the wind pressure distribution in the direction parallel to the rotation axis, the plurality of upper movable plates 12a are each moved to an optimal position. As a result, the wind pressure is mitigated. Therefore, turbulence in the airflow around the car 2 can be suppressed more reliably. As a result, noise inside the car 2 can be suppressed more reliably.

[0079] Furthermore, multiple lower movable plates 17a can also be moved by minute air pressure. In this case, corresponding to the air pressure distribution in the direction parallel to the rotation axis, the multiple lower movable plates 17a are each moved to an optimal position. As a result, the air pressure is mitigated. Therefore, turbulence in the airflow around the car 2 can be suppressed more reliably. As a result, noise inside the car 2 can be suppressed more reliably.

[0080] Alternatively, either the upper rectifier 10 or the lower rectifier 15 may be omitted. In this case, turbulence in the airflow around the car 2 can be suppressed more reliably. As a result, noise inside the car 2 can be suppressed more reliably.

[0081] Implementation Method 5

[0082] Figure 11 This is a top view of a key part of an elevator that uses the rectifier system of the elevator in embodiment 5. Figure 12 This is a bottom view of a key part of an elevator that uses the rectifier system of the elevator in Embodiment 5. Furthermore, parts that are the same as or equivalent to those in Embodiment 4 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0083] like Figure 11 and Figure 12 As shown, the rectifier system of Embodiment 5 is a system that adds an upper connector 22 and a lower connector 23 to the rectifier system of Embodiment 4.

[0084] The upper connecting body 22 connects to multiple upper movable plates 12a.

[0085] The lower connecting body 23 connects to multiple lower movable plates 17a.

[0086] According to Embodiment 4 described above, the upper connecting body 22 connects to a plurality of upper movable plates 12a. Therefore, noise generated by the vibration of the plurality of upper movable plates 12a due to slight changes in wind pressure can be suppressed.

[0087] Furthermore, the lower connecting body 23 connects to multiple lower movable plates 17a. Therefore, it is possible to suppress noise caused by the vibration of the multiple lower movable plates 17a due to slight changes in wind pressure.

[0088] Alternatively, either the upper rectifier 10 or the lower rectifier 15 may be omitted. In this case, noise generated by the vibration of the multiple upper movable plates 12a or the multiple lower movable plates 17a due to slight fluctuations in wind pressure can also be suppressed.

[0089] Implementation Method 6

[0090] Figure 13 and Figure 14 This is a front view of a key part of an elevator that uses the rectifier system of Embodiment 6. Additionally, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0091] like Figure 13 and Figure 14 As shown, counterweight 9 moves up and down on one side of car 2.

[0092] In the rectification system of embodiment 6, the upper rectification device 10 includes an upper rectifier 11, a pair of upper movable bodies 12, a pair of upper rotating shafts 13, and an upper connecting body 25.

[0093] The upper fairing 11 is spaced apart from the upper surface of the car 2 by a pair of upper support pillars 24.

[0094] One of the pair of upper movable bodies 12 serves as the main movable body and is adjacent to the edge of the upper fairing 11 on one side of the car 2. The other of the pair of upper movable bodies 12 serves as the secondary movable body and is adjacent to the edge of the upper fairing 11 on the other side of the car 2. The surface area of ​​the other of the pair of upper movable bodies 12 is smaller than that of the first of the pair of upper movable bodies 12.

[0095] One of the pair of upper rotating shafts 13 supports the edge of one of the pair of upper movable bodies 12 located on the central side of the car 2, allowing it to rotate freely. The other of the pair of upper rotating shafts 13 supports the edge of the other of the pair of upper movable bodies 12 located on the central side of the car 2, allowing it to rotate freely.

[0096] The upper connecting body 25 is positioned above the upper fairing 11. For example, the upper connecting body 25 is a line. One side of the upper connecting body 25 is connected to the side of one of the pair of upper movable bodies 12 opposite to the car 2. The other side of the upper connecting body 25 is connected to the side of the other of the pair of upper movable bodies 12 opposite to the car 2.

[0097] In the rectification system of embodiment 6, the lower rectification device 15 includes a lower rectifier 16, a pair of lower movable bodies 17, a pair of lower rotating shafts 18, and a lower connecting body 27.

[0098] The lower fairing 16 is spaced apart from the lower surface of the car 2 by a pair of lower support pillars 26.

[0099] One of the pair of lower movable bodies 17 serves as the main movable body and is adjacent to the edge of the lower fairing 16 on one side of the car 2. The other of the pair of lower movable bodies 17 serves as the secondary movable body and is adjacent to the edge of the lower fairing 16 on the other side of the car 2. The surface area of ​​the other of the pair of lower movable bodies 17 is smaller than that of the first of the pair of lower movable bodies 17.

[0100] One of the pair of lower rotating shafts 18 supports the edge of one of the pair of lower movable bodies 17 located on the central side of the car 2, allowing it to rotate freely. The other of the pair of lower rotating shafts 18 supports the edge of the other of the pair of lower movable bodies 17 located on the central side of the car 2, allowing it to rotate freely.

[0101] The lower connecting body 27 is disposed below the lower fairing 16. For example, the lower connecting body 27 is a line. One side of the lower connecting body 27 is connected to the side of one of the pair of lower movable bodies 17 opposite to the car 2. The other side of the lower connecting body 27 is connected to the side of the other of the pair of lower movable bodies 17 opposite to the car 2.

[0102] like Figure 13As shown, when the car 2 rises, the wind pressure experienced by one of the pair of upper movable bodies 12 is greater than that experienced by the other. As a result, one of the pair of upper movable bodies 12 tilts such that its outer edge is lower than its central edge. At this time, the other of the pair of upper movable bodies 12 is linked to one of them via the upper connecting body 25, thereby tilting its outer edge higher than its central edge.

[0103] In this state, the airflow around the upper part of the car 2 is directed to the counterweight 9 side.

[0104] like Figure 14 As shown, when the car 2 descends, the wind pressure experienced by one of the pair of lower movable bodies 17 is greater than that experienced by the other. As a result, one of the lower movable bodies 17 tilts such that its outer edge is positioned higher than its central edge. At this time, the other lower movable body 17 is linked to one of the lower movable bodies 17 via the lower connecting body 27, thereby tilting such that its outer edge is positioned lower than its central edge.

[0105] In this state, the airflow around the lower part of the car 2 is directed to the counterweight 9 side.

[0106] According to Embodiment 6 described above, when the car 2 rises, the air surrounding the upper part of the car 2 can be guided to the counterweight 9 side by a pair of upper movable bodies 12. When the car 2 descends, the air surrounding the lower part of the car 2 can be guided to the counterweight 9 side by a pair of lower movable bodies 17. In the hoistway space, the landing side of the car 2 is narrower than the other sides of the car 2. Therefore, wind noise generated by airflow passing through the narrow space can be suppressed. As a result, noise inside the car 2 can be suppressed.

[0107] Alternatively, only one of the upper rectifier 10 and the lower rectifier 15 of embodiment 6 may be provided.

[0108] In addition, at least one of the upper rectifier 10 and the lower rectifier 15 of embodiment 6 can be applied to an elevator in which the counterweight 9 moves up and down on the rear side of the car 2.

[0109] Implementation Method 7

[0110] Figure 15 This is a front view of the elevator car using the rectifier system of Embodiment 7. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0111] like Figure 15 As shown, the upper fairing 11 includes a first upper movable part 11b, a second upper movable part 11c, and an upper fixed part 11d.

[0112] For example, the first upper movable part 11b is located above the left side of the car 2. For example, the second upper movable part 11c is located above the right side of the car 2. For example, the upper fixed part 11d is located above the center of the car 2 in the left-right direction. For example, the upper fixed part 11d is located between the first upper movable part 11b and the second upper movable part 11c. For example, the upper fixed part 11d is fixed to the upper frame 4.

[0113] In the first upper movable part 11b, the edge located on the central side of the car 2 is rotatably mounted to the edge of the upper fixed part 11d. For example, in the first upper movable part 11b, the edge located on the central side of the car 2 is rotatably mounted to the edge of the upper fixed part 11d via a rotation axis. The first upper movable part 11b is configured such that, by rotating about the edge located on the central side of the car 2, the edge located on the outer side of the car 2 can be raised upwards.

[0114] In the second upper movable part 11c, the edge located on the central side of the car 2 is rotatably mounted to the edge of the upper fixed part 11d. For example, in the second upper movable part 11c, the edge located on the central side of the car 2 is rotatably mounted to the edge of the upper fixed part 11d via a rotation axis. The second upper movable part 11c is configured such that, by rotating about the edge located on the central side of the car 2, the edge located on the outer side of the car 2 can be raised upwards.

[0115] During normal elevator operation, the upper rectifier 10 is located above the car 2, close to the upper part of the car 2. Specifically, the first upper movable part 11b and the second upper movable part 11c are maintained on the same plane as the upper fixed part 11d.

[0116] When maintaining the elevator, the upper rectifier 10 is positioned above the car 2 and away from the car 2. Specifically, the first upper movable part 11b and the second upper movable part 11c are maintained in a state where their outer edges on the car 2 are raised upwards.

[0117] According to Embodiment 7 described above, during normal elevator operation, the upper rectifier 10 is located above the car 2, close to the upper part of the car 2. Therefore, even if the height of the top of the shaft is lowered, a gap can be ensured between the upper rectifier 10 and the top of the shaft when the car 2 is moved to the uppermost position.

[0118] Furthermore, during elevator maintenance, the upper rectifier 10 is positioned above the car 2, away from the car 2. Therefore, more vertical working space can be ensured directly above the car 2. As a result, maintenance personnel can easily perform elevator maintenance directly above the car 2.

[0119] Alternatively, although not shown, a stop for the upper rectifier can be provided to restrict the rotation of the first upper movable part 11b and the second upper movable part 11c. In this case, if the stop for the upper rectifier is used to maintain the states of the first upper movable part 11b and the second upper movable part 11c before and after they are raised upwards, the upper rectifier 10 can be maintained in a suitable state at various times during normal operation and maintenance of the elevator.

[0120] Furthermore, although not shown, an upper fairing force-applying body can be provided to apply force in the direction of rotation to the first upper movable part 11b and the second upper movable part 11c as they are raised upward toward the outer edge of the car 2. In this case, when maintaining the elevator, the operator can reduce the force required to raise the outer edge of the first upper movable part 11b and the second upper movable part 11c of the car 2.

[0121] Furthermore, although not shown, the first upper movable portion 11b and the second upper movable portion 11c can be further divided. In this case, the divided first upper movable portion 11b and the second upper movable portion 11c can be rotated independently via a rotation axis.

[0122] Implementation Method 8

[0123] Figure 16 This is a front view of the elevator car using the rectifier system of Embodiment 8. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0124] like Figure 16 As shown, the upper rectifier 10 includes multiple upper lifting support bodies 11e. These multiple upper lifting support bodies 11e are arranged above the car 2 in the width direction of the car 2. For example, the multiple upper lifting support bodies 11e are fixed to the upper surface of the upper frame 4. For example, the multiple upper lifting support bodies 11e are foldable pillars. The multiple upper lifting support bodies 11e support the upper rectifier 11 with a gap between them and the upper surface of the car 2. The multiple upper lifting support bodies 11e support the upper rectifier 11 so that it can move freely in the vertical direction.

[0125] During normal elevator operation, the upper rectifier 10 is located above the car 2, close to the upper part of the car 2. Specifically, by folding down the multiple upper lifting supports 11e, the upper rectifier 11 is maintained in a position directly above the upper frame 4.

[0126] During elevator maintenance, the upper rectifier 10 is positioned above the car 2, away from the upper part of the car 2. Specifically, multiple upper lifting supports 11e are released from their folded positions to form a straight line, thereby maintaining the upper rectifier 11 at a distance from the upper frame 4.

[0127] According to Embodiment 8 described above, during normal elevator operation, the upper rectifier 10 is located above the car 2, close to the upper part of the car 2. Therefore, even if the height of the top of the shaft is lowered, a gap can be ensured between the upper rectifier 10 and the top of the shaft when the car 2 is moved to the uppermost position.

[0128] Furthermore, during elevator maintenance, the upper rectifier 10 is positioned above the car 2, away from its upper part. Therefore, more vertical working space is ensured directly above the car 2. As a result, maintenance personnel can easily perform elevator maintenance directly above the car 2.

[0129] Alternatively, although not shown, a stop for the upper rectifier 10 can be provided to restrict its vertical movement. In this case, if the stop for the upper rectifier 10 is used to maintain the state before and after the upper rectifier 10 moves upward, the upper rectifier 10 can be kept in a suitable state during normal operation and maintenance of the elevator.

[0130] Furthermore, although not shown, a force-applying body for the upper rectifier device can also be provided to apply upward force to the upper rectifier 11. In this case, the force required for workers to move the upper rectifier 11 upward can be reduced when maintaining the elevator.

[0131] Furthermore, although not shown, the upper rectifier 10 can also be divided. In this case, the divided upper rectifier 10 can be moved independently in the vertical direction via the upper lifting support 11e.

[0132] Implementation Method 9

[0133] Figure 17 This is a side view of the elevator car using the rectifier system of Embodiment 9. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0134] like Figure 17As shown, the lower fairing 16 includes a first lower movable part 16a, a second lower movable part 16b, and a lower fixed part 16c.

[0135] For example, a first lower movable part 16a is provided below the front part of the car 2. For example, a second lower movable part 16b is provided below the rear part of the car 2. For example, a lower fixed part 16c is provided below the center part of the car 2 in the front-rear direction. For example, the lower fixed part 16c is provided between the first lower movable part 16a and the second lower movable part 16b. For example, the lower fixed part 16c is fixed to the lower frame 5.

[0136] In the first lower movable part 16a, the edge located on the central side of the car 2 is rotatably mounted to the edge of the lower fixed part 16c. For example, in the first lower movable part 16a, the edge located on the central side of the car 2 is rotatably mounted to the edge of the lower fixed part 16c via a rotation axis. The first lower movable part 16a is configured such that, by rotating about the edge located on the central side of the car 2, the edge located on the outer side of the car 2 can droop downward.

[0137] In the second lower movable part 16b, the edge located on the central side of the car 2 is rotatably mounted to the edge of the lower fixed part 16c. For example, in the second lower movable part 16b, the edge located on the central side of the car 2 is rotatably mounted to the edge of the lower fixed part 16c via a rotation axis. The second lower movable part 16b is configured such that, by rotating about the edge located on the central side of the car 2, the edge located on the outer side of the car 2 can droop downwards.

[0138] During normal elevator operation, the lower rectifier 15 is located below the car 2, close to the lower part of the car 2. Specifically, the first lower movable part 16a and the second lower movable part 16b are maintained on the same plane as the lower fixed part 16c.

[0139] During elevator maintenance, the lower rectifier 15 is positioned below the car 2 and away from the car 2. Specifically, the first lower movable part 16a and the second lower movable part 16b maintain a downward-hanging position at their outer edges on the car 2.

[0140] According to Embodiment 9 described above, during normal elevator operation, the lower rectifier 15 is located below the car 2, close to the lower part of the car 2. Therefore, even if the depth of the bottom of the shaft is reduced, a gap can be ensured between the lower rectifier 15 and the bottom of the shaft when the car 2 is moved to its lowest position.

[0141] Furthermore, during elevator maintenance, the lower rectifier 15 is positioned below the car 2, away from the car 2. Therefore, more vertical working space can be ensured directly below the car 2. As a result, maintenance personnel can easily perform elevator maintenance directly below the car 2.

[0142] Alternatively, although not shown, a stop for the lower fairing can be provided to restrict the rotation of the first lower movable part 16a and the second lower movable part 16b. In this case, if the stop for the lower fairing is used to maintain the states of the first lower movable part 16a and the second lower movable part 16b before and after they droop downwards, the lower fairing device 15 can be maintained in a suitable state at various times during normal operation and maintenance of the elevator.

[0143] Furthermore, although not shown, a force-applying body for the lower fairing can be provided to apply force in the direction of rotation to the first lower movable part 16a and the second lower movable part 16b, which are raised towards the edge furthest from the lower fixed part 16c. In this case, when maintaining the elevator, the force required for the operator to raise the edge furthest from the lower fixed part 16c of the first lower movable part 16a and the second lower movable part 16b upwards can be reduced.

[0144] Furthermore, although not shown, the first lower movable portion 16a and the second lower movable portion 16b can be further divided. In this case, the divided first lower movable portion 16a and the second lower movable portion 16b can be rotated independently via a rotation axis.

[0145] Implementation Method 10

[0146] Figure 18 This is a side view of the elevator car that uses the rectifier system of the elevator in Embodiment 10. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0147] like Figure 18 As shown, the lower rectifier 15 includes a plurality of lower lifting supports 16e. The plurality of lower lifting supports 16e are arranged below the car 2 in the depth direction of the car 2. For example, the plurality of lower lifting supports 16e are fixed to the lower frame 5. For example, the plurality of lower lifting supports 16e are retractable support columns. The plurality of lower lifting supports 16e support the lower rectifier 16 with a gap between them and the lower surface of the car 2. The plurality of lower lifting supports 16e support the lower rectifier 16 so that it can move freely in the vertical direction.

[0148] During normal elevator operation, the lower rectifier 15 is located below the car 2, close to the lower part of the car 2. Specifically, by retracting the multiple lower lifting supports 16e, the lower rectifier 16 is maintained in a position directly below the lower frame 5.

[0149] During elevator maintenance, the lower rectifier 15 is positioned below the car 2, away from the lower part of the car 2. Specifically, by extending each of the multiple lower lifting supports 16e, the lower rectifier 16 maintains a gap between itself and the lower frame 5.

[0150] According to the embodiment 10 described above, during normal elevator operation, the lower rectifier 15 is located below the car 2, close to the lower part of the car 2. Therefore, even if the depth of the bottom of the shaft is reduced, a gap can be ensured between the lower rectifier 15 and the bottom of the shaft when the car 2 moves to its lowest position.

[0151] Furthermore, during elevator maintenance, the lower rectifier 15 is positioned below the car 2, away from the car 2. Therefore, more vertical working space can be ensured directly below the car 2. As a result, maintenance personnel can easily perform elevator maintenance directly below the car 2.

[0152] Alternatively, although not shown, a stop for the lower rectifier 15 can be provided to restrict its vertical movement. In this case, if the stop for the lower rectifier 15 is used to maintain both the state before and after the lower rectifier 15 moves upward, the lower rectifier 15 can be kept in a suitable state during normal operation and maintenance of the elevator.

[0153] Furthermore, although not shown, a force-applying body for the lower rectifier 15 can also be provided to apply upward force to the lower rectifier 15. In this case, the force required for the operator to move the lower rectifier 16 upward during elevator maintenance can be reduced.

[0154] Furthermore, although not shown, the lower rectifier 15 can also be divided. In this case, the divided lower rectifier 15 can be moved independently in the vertical direction via the lower lifting support 16e.
