[0028] Description is made with reference to the accompanying drawings. In addition, the same reference numerals are assigned to the same or corresponding parts in each drawing. Duplicate descriptions of such parts are appropriately simplified or omitted.

[0029] Embodiment 1.

[0030] Figure 1 is an overall view of an elevator apparatus.

The main suspension ropes 3 are wound around the hoist 2. The car chamber 5 is moved up and down by winding the main suspension ropes 3 around the hoist 2. The counterweight 4 is suspended on the other side of the main suspension ropes 3. The counterweight 4 moves up and down in the direction opposite to the car 1.

[0035] The door 6 has a rectangular shape. The door 6 is provided at the entrance and exit of the car chamber 5. The door 6 faces the door of the landing provided on each floor.

[0036] The car frame 7 has a rectangular shape. The car frame 7 supports the car chamber 5. The car frame 7 is provided with vertical beams and horizontal beams. The vertical beams extend in the vertical direction. The vertical beams are provided with a vertical column 12 and a Figure 1 vertical column 13 not shown in the figure. The car chamber 5 is arranged between the vertical column 12 and the vertical column 13. The horizontal beams extend in the opening and closing direction of the door 6. The horizontal beams are provided with an upper beam 14 and a lower beam 15. The upper beam 14 is connected between the upper end portion of the vertical column 12 and the upper end portion of the vertical column 13. The upper beam 14 is arranged above the car chamber 5. The main suspension ropes 3 are connected to the upper beam 14. The lower beam 15 is connected between the lower end portion of the vertical column 12 and the lower end portion of the vertical column 13. The lower beam 15 is arranged below the car chamber 5.

[0037] To make the following description easier, an x-axis and a y-axis are set. The x-axis is a horizontal axis parallel to the direction in which the horizontal beams extend. The y-axis is a horizontal axis orthogonal to the x-axis.

[0038] A ventilation device 8 is installed above the car compartment 5. The ventilation device 8 is supported by the upper beam 14. The ventilation device 8 has a frame and a cover 16 made of soft material. The ventilation device 8 suppresses wind noise when the car 1 rises and falls. A sling hole 17 is formed in the upper part of the cover 16 for the main sling 3 to pass through.

[0039] The cover fixing part 9 has a mechanism for fixing the cover 16 of the air rectifier 8.

[0040] A sill 10 and a baffle 11 are installed at the lower end of the landing side of the car compartment 5 for the purpose of preventing falls. The sill 10 is located below the door. The baffle 11 is located below the sill 10.

[0041] Furthermore, the car 1 can also be used in elevator systems that do not have a machine room. In this case, the hoist 2 and the control device are located at the bottom or top of the hoisting passage.

[0042] Next, use Figures 2 to 4 The frame of the air purifier 8 will be described.

[0043] Figure 2 This is a side view of the elevator car 1 with its cover 16 removed. Figure 3 This is the front view when the cover 16 of the elevator car 1 is removed. Figure 4 This is a top view when the cover 16 of the elevator car 1 is removed.

[0044] like Figure 2 As shown, the frame of the air purifier 8 includes a support platform 18, a first pipe 19, and a second pipe 20.

[0045] The support platform 18 is positioned above the upper beam 14. The support platform 18 is fixed to the upper beam 14.

[0046] The first tube 19 has a first rod-shaped portion 21 and a first curved portion 22. The first rod-shaped portion 21 extends away from the door 6 along the y-axis from the end on the door 6 side. The first rod-shaped portion 21 is positioned above the upper beam 14. The first rod-shaped portion 21 is supported by the upper beam 14. The first curved portion 22 bends downward from the other end of the first rod-shaped portion 21 toward the car compartment 5 and extends in a vertical direction. The first tube 19 is positioned above the support platform 18. The first tube 19 is fixed to the support platform 18. A space is formed between the end of the first tube 19 on the side of the first curved portion 22 and the car compartment 5.

[0047] like Figure 3As shown, the second pipe 20 has a second rod-shaped portion 23, a second curved portion 24, and a third curved portion 25. The second rod-shaped portion 23 extends along the x-axis. The second curved portion 24 bends downward toward the car compartment 5 from one end of the second rod-shaped portion 23 and extends vertically. This end of the second rod-shaped portion 23 is the end facing left from the door 6 side. The third curved portion 25 bends downward toward the car compartment 5 from the other end of the second rod-shaped portion 23 and extends vertically. This end of the second rod-shaped portion 23 is the end facing right from the door 6 side. The second pipe 20 is positioned above the first pipe 19. The second pipe 20 is fixed to the first pipe 19. A gap is formed between the end of the second pipe 20 on the second curved portion 24 side and the car compartment 5. A space is formed between the end of the second pipe 20 on the third curved portion 25 side and the car compartment 5.

[0048] Furthermore, the second pipe 20 is positioned above the first pipe 19 such that, on the vertical projection plane, the distance between the second rod-shaped portion 23 and the car compartment 5 is longer than the distance between the first rod-shaped portion 21 and the car compartment 5. That is, on the vertical projection plane, the second rod-shaped portion 23 of the second pipe 20 is farther from the car compartment 5 than the first rod-shaped portion 21 of the first pipe 19.

[0049] like Figure 4 As shown, the first rod-shaped portion 21 of the first pipe 19 intersects the upper beam 14 on the horizontal projection plane. The main suspension cable 3 is connected to the center of the upper beam 14. The second rod-shaped portion 23 of the second pipe 20 intersects the first pipe 19 on the horizontal projection plane.

[0050] Next, the positions of the first tube 19 and the second tube 20 will be explained. Figure 4 In the specific example shown, the frame of the air rectifier 8 includes two support platforms 18, two first pipes 19, and three second pipes 20. Hereinafter, when it is necessary to determine the two support platforms 18, as... Figure 4 As shown, the support platform 18 is labeled with reference numerals 18a to 18b. Similarly, the first tube 19 is labeled with reference numerals 19a to 19b. Furthermore, the second tube 20 is labeled with reference numerals 20a to 20c. In addition, the components of the first tube 19a are identified by adding the letter 'a' after the reference numeral. Similarly, the components of the first tube 19b are identified by adding the letter 'b' after the reference numeral. The components of the second tube 20a are identified by adding the letter 'a' after the reference numeral. The components of the second tube 20b are identified by adding the letter 'b' after the reference numeral. The components of the second tube 20c are identified by adding the letter 'c' after the reference numeral.

[0051] Support platform 18a is positioned on the horizontal projection plane, facing left from the door 6 side relative to the main hoisting cable 3. Support platform 18a is located within the area of ​​the car compartment 5 on the horizontal projection plane. Support platform 18b is positioned on the horizontal projection plane, facing right from the door 6 side relative to the main hoisting cable 3. Support platform 18b is located within the area of ​​the car compartment 5 on the horizontal projection plane.

[0052] The first tube 19a is positioned above the support platform 18a. The first rod-shaped portion 21a of the first tube 19a is fixed to the support platform 18a. The first tube 19a is fixed at the intersection with the upper beam 14. The first tube 19b is positioned above the support platform 18b. The first rod-shaped portion 21b of the first tube 19b is fixed to the support platform 18b. The first tube 19b is fixed at the intersection with the upper beam 14. The first tubes 19a and 19b are positioned at the same height.

[0053] The second tube 20a is positioned above the end of the first rod-shaped portion 21a on the door 6 side. The second tube 20a is positioned above the end of the first rod-shaped portion 21b on the door 6 side. The second tube 20a intersects the first tube 19a in the horizontal projection plane. The second tube 20a intersects the first tube 19b in the horizontal projection plane. The second tube 20a is fixed to the first tube 19a at the intersection with the first tube 19a. The second tube 20a is fixed to the first tube 19b at the intersection with the first tube 19b. The second tube 20b is positioned between the second tube 20a and the support platform 18a and support platform 18b in the horizontal projection plane. The second tube 20b intersects the first tube 19a in the horizontal projection plane. The second tube 20b intersects the first tube 19b in the horizontal projection plane. The second tube 20b is fixed to the first tube 19a at the intersection with the first tube 19a. The second tube 20b is fixed to the first tube 19b at the intersection with the first tube 19b. The second pipe 20c is configured to form the first bend 22a side and the first bend 22b side on the horizontal projection plane compared to the connection points of the main sling 3 and the upper beam 14. The second pipe 20c intersects the first pipe 19a on the horizontal projection plane. The second pipe 20c intersects the first pipe 19b on the horizontal projection plane. The second pipe 20c is fixed to the first pipe 19a at the intersection point with the first pipe 19a. The second pipe 20c is fixed to the first pipe 19b at the intersection point with the first pipe 19b.

[0054] Hollow tubes with rounded edges are used as the materials for the first tube 19 and the second tube 20. Alternatively, square tubes with sharp edges can be used, but since the cover 16 made of soft material may have holes or break, it is preferable to use a rounded material without sharp edges.

[0055] The first tube 19 connects the support platform 18 to the second tube 20. The shape of the first bend 22 determines the shape of the cover 16 in the y-axis direction. The shapes of the second bend 24 and the third bend 25 determine the shape of the cover 16 in the x-axis direction. Therefore, the shape of the cover 16 can be determined by the first tube 19 and the second tube 20. This reduces the number of components and improves installability. Furthermore, the construction is simplified, and assembly is easier.

[0056] Next, use Figure 5 The following explanation is given regarding cover 16. Figure 5 This is a side view of elevator car 1.

[0057] The cover 16 is shaped like a frame along the interior of the ventilation device 8. The cover 16 is configured to cover the first pipe 19 and the second pipe 20 from the outside. An opening is formed at the bottom of the cover 16. A concave cutout is formed on the side of the cover 16 along the x-axis. One cutout is formed on the side of the cover 16 facing right from the door 6, and another is formed on the side of the cover 16 facing left from the door 6. The cutout is at a depth to which the cover 16 does not overlap with the car frame 7. The upper beam 14 passes through the cutout. The cover 16 has connecting portions 26 at at least eight locations, including the lower corner of the cutout and the ends at positions that form corners in the horizontal projection plane.

[0058] As the material for the cover 16, soft materials such as cloth, resin, and paper can be used that can conform to the shape of the internal frame of the air-conditioning device 8. When using metal sheets as the material for the cover 16, multiple sheet metal parts and bolts are required. Furthermore, the sheet metal parts need to be bent. Therefore, manufacturing costs increase, and assembly takes time. By using soft materials, sheet metal parts and bending processes are eliminated. In addition, compared to using metal sheets, the number of bolts and other parts can be reduced. Therefore, by using a cover 16 made of soft materials, costs can be reduced compared to using metal sheets, and installation and maintainability are improved.

[0059] Next, it also used Figure 5 and Figure 6 The fixing part 9 of the cover will be explained. Figure 6 This is the front view of elevator car 1.

[0060] Cover fixing parts 9 are provided at the upper and lower parts of cover 16. The cover fixing part 9 at the upper part of cover 16 includes a first fixing member 27 such as a bolt. Cover 16 overlaps with the second tube 20b in the horizontal projection plane. Cover 16 overlaps with the second tube 20c in the horizontal projection plane. Cover fixing parts 9 are provided at the overlapping portion of cover 16 and the second tube 20b. Cover fixing parts 9 are provided at the overlapping portion of cover 16 and the second tube 20c. Cover 16 is fixed from above by the first fixing member 27. Cover 16 is fixed to the second tube 20b. Cover 16 is fixed to the second tube 20c. The first fixing member 27 is positioned in the horizontal projection plane closer to the upper beam 14 than the second tube 20a.

[0061] Next, it also used Figure 5 and Figure 6 The cover fixing part 9 at the lower part of the cover 16 will be described.

[0062] exist Figure 5 and Figure 6 In the example shown, the car 1 has a fixing cable 28. The cover fixing part 9 has a second fixing member 29. One side of the fixing cable 28 is connected to the connecting part 26 of the cover 16. The second fixing member 29 is hook-shaped. The second fixing member 29 is fixed to the car frame 7. The other side of the fixing cable 28 is fixed to the second fixing member 29. Therefore, the lower part of the cover is fixed to the car 1 under tension. A space is formed between the lower edge of the cover 16 and the car compartment 5.

[0063] Next, the advantages of the position of the cover 16 will be explained. When the car compartment 5 is configured to match the height of the landing, the door 6 is positioned closer to the landing than the cover 16 in the horizontal projection plane. Therefore, a space is formed between the cover 16 and the equipment in the lifting passage in the horizontal projection plane. Thus, interference between the cover 16 and the equipment in the lifting passage can be prevented.

[0064] Next, the advantages of the position of the cover fixing part 9 will be explained. The cover 16 has a surface 30. Surface 30 is the surface facing the door provided at the landing when the car 1 is moving. The door 6 has a surface 31. Surface 31 is the surface facing the door provided at the landing when the car 1 is moving. Surface 31 is the surface furthest from the car frame 7 among the surfaces of the door 6 in the horizontal projection plane. Surface 30 is positioned on the horizontal projection plane closer to the upper beam 14 than surface 31. Surface 30 is the closest to the equipment in the lifting passage among the surfaces of the cover 16. In order to prevent interference between the cover 16 and the equipment in the lifting passage, surface 30 needs to reduce deflection. The cover fixing part 9 is positioned on the horizontal projection plane closer to the upper beam 14 than the second pipe 20a. Therefore, tension is generated in surface 30, making it difficult to deflect. In addition, by utilizing tension in the fixing of the cover 16, the fixing parts of the cover 16 can be reduced. Therefore, the number of parts can be reduced, and the installation performance is improved.

[0065] Next, the shape of the air rectifier 8 will be explained. Noise generated during lifting and lowering can easily flow into the car compartment 5 through the gap between the car compartment 5 and the door 6. To suppress noise, it is necessary to reduce the airflow towards the door 6. The shape of the air rectifier 8 is determined by the shape of the first pipe 19 and the second pipe 20. The first pipe 19 has a first bend 22, and the end on the door 6 side does not have a bend. The second pipe 20 has a second bend 24 and a third bend 25. The cover 16 of the air rectifier 8 is curved and streamlined on its upper part other than the surface 30 due to the shapes of the first pipe 19 and the second pipe 20. Therefore, air near the surface of the cover 16 easily flows along the surface other than the surface 30 when the car 1 rises. Thus, the airflow along the surface 30 can be suppressed. Therefore, the air rectifier 8 can reduce the airflow towards the door 6. This reduces noise within the car compartment 5.

[0066] Next, the advantages of the positional relationship between the first pipe 19 and the second pipe 20 during assembly will be explained. The car frame 7 is one of the strongest components in the car 1. Therefore, the ventilation system 8 is installed on the car frame 7. The frame of the ventilation system 8 includes a support platform 18, the first pipe 19, and the second pipe 20. The support platform 18 is fixed to the upper beam 14. The first pipe 19 is positioned above the support platform 18. The first pipe 19 is positioned along the y-axis in the horizontal projection plane. Therefore, the first pipe 19 intersects the upper beam 14 in the horizontal projection plane. Therefore, the first pipe 19 can be fixed to the support platform 18 at the intersection with the upper beam 14. The second pipe 20 is positioned above the first pipe 19. The second pipe 20 is positioned along the x-axis in the horizontal projection plane. Therefore, the second pipe 20 intersects the first pipe 19 in the horizontal projection plane. Therefore, the second pipe 20 can be fixed to the first pipe 19 at the intersection with the first pipe 19. On the other hand, the second pipe 20 does not intersect the upper beam 14. Therefore, when the second tube 20 is installed below the first tube 19, additional components are required for fixing. Thus, compared to a frame with the second tube 20 positioned below the first tube 19, a frame with the second tube 20 positioned above the first tube 19 reduces the number of components and improves installability. Furthermore, the construction is simplified, and assembly becomes easier.

[0067] Next, use Figure 7 The advantages of the positional relationship between the first pipe 19 and the second pipe 20 during the lifting and lowering of the car 1 are explained.

[0068] Figure 7 This is a central sectional view of the elevator car 1 showing the relationship between the airflow during ascent and the shape of the cover 16.

[0069] like Figure 7As shown, the second pipe 20 is positioned above the first pipe 19. When the car 1 rises, a downward airflow A is generated. Due to the downward pressure generated by airflow A, the upper part of the cover 16 flexes along the x-axis between the second pipes 20a and 20b, and between the second pipes 20b and 20c. As a result, the flexed portion acts like a groove. Therefore, near the surface of the upper part of the cover 16, airflow B in the x-axis direction is easily generated, while airflow C in the y-axis direction is difficult to generate. Thus, the airflow C generated towards the door 6, which is a cause of noise, can be reduced. On the other hand, when the first pipe 19 and the second pipe 20 are at the same height, the upper part of the cover 16 flexes in a quadrilateral shape along both the x-axis and y-axis directions. Therefore, near the surface of the upper part of the cover 16, airflow B and airflow C generate airflow of equal magnitude. Therefore, a state where airflow C in the y-axis direction is difficult to generate is not formed. Furthermore, when the first pipe 19 is positioned above the second pipe 20, the upper part of the cover 16 flexes along the y-axis between the first pipe 19a and the first pipe 19b. Therefore, airflow C in the y-axis direction is easily generated near the surface of the upper part of the cover 16, while airflow B in the x-axis direction is difficult to generate. Consequently, a state where airflow C in the y-axis direction is difficult to generate is not formed. Thus, by positioning the second pipe 20 above the first pipe 19, the flow rate of air flowing towards the door 6 can be suppressed. This reduces noise within the car compartment 5.

[0070] Figures 2 to 7 An example is shown where the air purifier 8 has two first pipes 19 and three second pipes 20. As another example, the air purifier 8 may also have only one first pipe 19 and one second pipe 20. Furthermore, in order to create a configuration that easily generates an airflow B in the x-axis direction near the upper surface of the cover 16 when the car 1 rises, the air purifier 8 preferably has multiple first pipes 19 and multiple second pipes 20. For example, the air purifier 8 may also have two first pipes 19 and two second pipes 20.

[0071] exist Figures 2 to 7 The text describes a frame structure with a support platform 18 between the upper beam 14 and the first tube 19, but the first tube 19 can also be fixed above the upper beam 14 without using the support platform 18.

[0072] Furthermore, the ventilation device 8 can also be installed below the car compartment 5. Alternatively, the ventilation device 8 can be installed both above and below the car compartment 5. When the ventilation device 8 is installed below the car compartment 5, the ventilation device 8 is arranged in opposite directions. Additionally, the support platform 18 or the first pipe 19 is fixed below the lower beam 15. By installing the ventilation device 8 below the car compartment 5, noise during the descent of the car 1 can be suppressed.

[0073] According to Embodiment 1 described above, the air rectifier 8 includes a cover 16 and a frame. The shape of the frame of the air rectifier 8 is determined by the shapes of the first pipe 19 and the second pipe 20. In the horizontal projection plane, the first pipe 19 and the second pipe 20 intersect. The frame of the air rectifier 8 is manufactured by intersecting the two components. Therefore, the number of components can be reduced, and the installability is improved. Moreover, the structure becomes simple, and the assembly operation becomes easy.

[0074] The first tube 19 is positioned below the second tube 20. The first tube 19 intersects the second tube 20 in the horizontal projection plane. The second tube 20 intersects the first tube 19 in the horizontal projection plane. Therefore, the first tube 19 can be fixed at the intersection with the upper beam 14 or the support platform 18. Furthermore, the second tube 20 can be fixed at the intersection with the first tube 19. Thus, the number of components required for fixing can be reduced. This further improves installability and simplifies assembly.

[0075] The first pipe 19 has a first rod-shaped portion 21 and a first curved portion 22. The second pipe 20 has a second rod-shaped portion 23, a second curved portion 24, and a third curved portion 25. As a result, the airflow generated towards the door 6, which is a cause of noise, can be suppressed.

[0076] The first pipe 19 is positioned lower than the second pipe 20. Therefore, it is easier to generate airflow along the x-axis but harder to generate airflow along the y-axis. This further suppresses the airflow generated towards the door 6, which is a source of noise.

[0077] The cover 16 is fixed by the cover fixing part 9. Therefore, tension is applied to the cover 16 to prevent deflection. Thus, the air straightening device 8 can reduce the number of fixing parts of the cover 16. As a result, the installability is further improved, and the assembly operation becomes easier.

[0078] When the car compartment 5 is configured to match the height of the landing, the door 6 is positioned closer to the landing than the cover 16 on the horizontal projection plane. This prevents interference between the cover 16 and the equipment within the lifting passage.

[0079] The cover 16 is made of a soft material. Since it can align with the frame of the air-conditioning device 8, bending or other bending processes are unnecessary during manufacturing. Furthermore, the cover 16 is foldable. This facilitates its transport. Moreover, the cover 16 can be unfolded from its folded state and installed on the frame above the car 1. This improves portability and installation, and simplifies assembly.

[0080] Implementation method 2.

[0081] Figure 8This is a perspective view of the soft material cover 16 installed on the frame of the ventilation device 8. Furthermore, the same reference numerals are used for parts that are the same as or equivalent to those in Embodiment 1. Description of these parts is omitted.

[0082] like Figure 8 As shown, in Embodiment 2, the cover 16 has an opening and closing mechanism 32 that can be opened and closed on the line connecting the sling hole 17 to the end of the cover 16. The opening and closing mechanism 32 is a mechanism that can open and close the cover 16. The opening and closing mechanism 32 can be, for example, a zipper, button, or bolt. The opening and closing mechanism 32 is provided on the surface 30. The opening and closing mechanism 32 is closed when the elevator is in use. Therefore, the ventilation device 8 can maintain its ventilation function when the elevator is in use. On the other hand, when the cover 16 needs to be disassembled for maintenance and inspection of the elevator, the opening and closing mechanism 32 can be opened. In addition, the opening and closing mechanism 32 may also be provided on a side other than the surface 30, but from the viewpoint that it is easier to perform the opening and closing operation of the opening and closing mechanism 32 from the landing and to facilitate the operation of boarding and alighting from the landing to the top of the car room 5 by partially opening the opening and closing mechanism 32, it is preferable to provide it on the surface 30.

[0083] According to Embodiment 2 described above, the cover 16 has an opening and closing mechanism 32 on its surface 30. Therefore, the cover 16 can be opened. Thus, even with the main hoisting cable 3 attached to the car frame 7, the cover 16 can be attached and detached from the frame. Furthermore, the car 1 can perform the opening and closing operation of the cover 16 from the landing. Additionally, the cover 16 can be partially opened. Therefore, the maintainability of the car 1 is improved, and the operation of boarding and alighting from the landing to the top of the car compartment 5 becomes easier. Therefore, compared to the car 1 disclosed in Embodiment 1, installation and maintainability are improved.

[0084] Implementation method 3.

[0085] Figure 9 This is a side view showing elevator car 1. Figure 10 This is a front view showing elevator car 1. Figure 11 This is a side view of the elevator car 1 with the soft material cover 16 removed. Furthermore, the same reference numerals are used for any parts that are identical or equivalent to those in Embodiments 1 and 2. Description of these parts is omitted.

[0086] In embodiment 3, the ventilation device 8 of the car 1 includes a first pipe 19, a second pipe 20 and a cover 16.

[0087] like Figure 9 As shown, the upper part of the cover 16 has an inclined surface that rises from the side of the door 6.

[0088] like Figure 10 As shown, an opening 33 for maintenance work is formed on the surface 30 of the cover 16.

[0089] like Figure 11 As shown, the first rod-shaped portion 21 has an inclined portion 34 that slopes upward toward the end facing the door 6. Along with the shape of the first rod-shaped portion 21, the second tube 20b, fixed to the inclined portion 34, is positioned higher than the second tube 20c. Compared to the second curved portion 24c, the portion of the second curved portion 24b extending in the vertical direction is longer. Compared to the third curved portion 25c, the portion of the third curved portion 25b extending in the vertical direction is longer. Similarly, the second tube 20a, fixed to the inclined portion 34, is positioned higher than the second tube 20b. Compared to the second curved portion 24b, the portion of the second curved portion 24a extending in the vertical direction is longer. Compared to the third curved portion 25b, the portion of the third curved portion 25a extending in the vertical direction is longer.

[0090] According to Embodiment 3 described above, the cover 16 has an opening 33 formed on the surface 30. Therefore, compared with the cover 16 of Embodiment 1, the area of ​​the cover 16 along the frame is smaller. In addition, compared with the operation performed in the example disclosed in Embodiment 1, the operation of boarding and alighting from the landing to the top of the car compartment 5 becomes easier. As a result, the installation and maintainability are higher than those of Embodiment 1. The upper part of the cover 16 has an inclined surface that rises towards the door 6 side. When the car 1 rises and falls, the air near the surface of the cover 16 tends to flow downward along the inclined surface of the upper part of the cover 16, and it is difficult for it to flow towards the surface 30. Therefore, it is possible to suppress the flow of airflow from the opening 33 on the surface 30 into the interior of the cover 16. As a result, it is possible to suppress the noise in the car compartment 5 during rise and fall. Furthermore, although it is also possible to form an opening 33 on the cover 16 with a non-inclined upper surface, since the airflow tends to enter the interior of the cover 16 from the opening 33, the cover 16 is preferably sloping in a shape that rises towards the door 6 side.

[0091] Implementation method 4.

[0092] Figure 12 This is a central sectional view showing the elevator car 1. Furthermore, the same reference numerals are used for any parts that are identical or equivalent to those in Embodiments 1 through 3. Descriptions of these parts are omitted.

[0093] like Figure 12 As shown, in Embodiment 4, an opening 33 is formed on the surface 30 of the cover 16, similar to Embodiment 3. The end of the cover 16 is fixed to the car chamber 5 by the cover fixing part 9.

[0094] The cover fixing part 9 includes an L-shaped fixing component 35 and a bolt 36. The cover fixing part 9 is located between the end of the car compartment 5 and the cover 16.

[0095] The L-shaped fixing member 35 is fixed to the car compartment 5. A vertical elongated hole is formed at the end of the cover 16 for fixing the bolt 36. The cover 16 is fixed to the L-shaped fixing member 35 by the bolt 36. The bolt 36 passes through the elongated hole of the cover 16. The bolt 36 is fastened to the L-shaped fixing member 35. The bolt 36 is not fully tightened. The bolt 36 is tightened such that the cover 16 can move up and down by an amount corresponding to the vertical length of the elongated hole. Therefore, the cover 16 is not completely fixed. The cover 16 is fixed in a state where there is no gap between it and the car compartment 5.

[0096] The car compartment 5 is supported by the car frame 7 via vibration-damping rubber. The vibration-damping rubber suppresses swaying within the car compartment 5 during passenger boarding and alighting. Depending on the number of passengers, the car frame 7 may sometimes move differently from the car compartment 5 by an amount corresponding to the displacement of the vibration-damping rubber. When the bolts 36 are fully tightened, tension that could damage the cover 16 may be applied. Damage to the cover 16 can be prevented by making the holes through which the bolts 36 pass elongated and adjusting the tightening strength of the bolts 36.

[0097] According to Embodiment 4 described above, the cover 16, like in Embodiment 3, has an opening 33 formed on surface 30. Therefore, the area of ​​the cover 16 along the frame is smaller than that of the cover 16 in Embodiment 1. Furthermore, compared to the operations performed in Embodiment 1, the operation of boarding and alighting from the landing to the top of the car compartment 5 becomes easier. Thus, compared to Embodiment 1, installation and maintainability are further improved. The end of the cover 16 is fixed to the car compartment 5 using the cover fixing part 9. Therefore, there is no airflow path between the car compartment 5 and the cover 16. Therefore, even with the opening 33 formed, airflow from the opening 33 to the inside of the cover 16 can be suppressed. Therefore, noise can be reduced without changing the shape of the first pipe 19 and the second pipe 20. Therefore, the structure is simpler than in Embodiment 3. Therefore, installation is improved compared to Embodiment 3. In addition, the cover 16 is fixed in a state where there is no gap between it and the car compartment 5. Therefore, when the ventilation device 8 is positioned above the car 1, there is no need for handrails to prevent falls.

[0098] Implementation method 5.

[0099] Figure 13 This is a side view of the elevator car 1, showing the method of fixing the cover 16 of the soft material. Furthermore, the same reference numerals are used for any of the parts that are the same or equivalent to those in Embodiments 1 to 4. Descriptions of these parts are omitted.

[0100] like Figure 13As shown, in embodiment 5, the fixed sling 28 includes a tension adjustment mechanism 37. The tension adjustment mechanism 37 uses a component such as a spring that can adjust the tension of the fixed sling 28. By adjusting the tension of the fixed sling 28 using the tension adjustment mechanism 37, tension is applied to the cover 16.

[0101] Alternatively, the tension adjustment mechanism 37 can be omitted, and a flexible sling can be used as a fixed sling.

[0102] In addition, the second fixing member 29 can also be fixed to the car compartment 5. When the second fixing member 29 is fixed to the car compartment 5, the second fixing member 29 is fixed on the horizontal projection plane at a position closer to the upper beam 14 than the second pipe 20a.

[0103] According to Embodiment 5 described above, the fixing sling 28 includes a tension adjustment mechanism 37. The tension of the fixing sling 28 is adjusted using the tension adjustment mechanism 37. The tension of the fixing sling 28 is used to apply tension to the cover 16. The tension applied to the cover 16 can prevent deflection of the cover 16 due to wind pressure generated during lifting. Therefore, compared to the example disclosed in Embodiment 1, the number of fastening connections of the first fixing member 27 can be reduced. Moreover, compared to the example disclosed in Embodiment 1, the number of fixing slings 28 can be reduced. Thus, compared to the example disclosed in Embodiment 1, the number of components can be reduced, thereby improving installability and maintainability.

[0104] Implementation method 6.

[0105] Figure 14 It is a side view of the elevator car 1 and shows the method of fixing the cover 16 of the soft material. Figure 15 This is a front view of the elevator car 1, showing the method of fixing the cover 16 of the soft material. Furthermore, the same reference numerals are used for any of the parts that are the same or equivalent to those in Embodiments 1 to 5. Descriptions of these parts are omitted.

[0106] like Figure 14 As shown, in Embodiment 6, the car compartment 5 includes a handrail 38. The handrail 38 is located above the car compartment 5. The handrail 38 is provided to prevent falls. Additionally, the fixing cable 28, like in Embodiment 5, includes a tension adjustment mechanism 37. The cover fixing part 9 has a fastening connection mechanism for securely connecting the fixing cable 28 and the handrail 38. The fixing cable 28 is fixed to the handrail 38 via the cover fixing part 9. The cover fixing part 9 is located on the horizontal projection plane at a position closer to the upper beam 14 than the second pipe 20a. Furthermore, a ventilation device 8 is located above the car compartment 5. The ventilation device 8 is supported by the upper beam 14.

[0107] like Figure 14 and Figure 15As shown, when a handrail 38 is provided above the car compartment 5, the handrail 38 is positioned directly below the end of the cover 16. Therefore, the first bend 22 of the first tube 19 can be made shorter in the vertical direction than in the example disclosed in Embodiment 1. The second bend 24 of the second tube 20 can be made shorter in the vertical direction than in the example disclosed in Embodiment 1. The third bend 25 of the second tube 20 can be made shorter in the vertical direction than in the example disclosed in Embodiment 1. The fixing cable 28 applies tension to the cover 16 by adjusting the tension using the tension adjustment mechanism 37.

[0108] According to Embodiment 6 described above, the fixed sling 28 is equipped with a tension adjustment mechanism 37. The car compartment 5 is equipped with a handrail 38. The fixed sling 28 is fixed to the handrail 38. The handrail 38 is located directly below the end of the cover 16. Therefore, compared with the example disclosed in Embodiment 1, the air rectifier 8 can shorten the length of the first pipe 19 and the length of the second pipe 20. Therefore, compared with Embodiment 1, the weight of the first pipe 19 and the weight of the second pipe 20 can be reduced. As a result, installation and maintainability are improved compared with the example disclosed in Embodiment 1. In addition, similarly to Embodiment 5, the tension of the fixed sling 28 is adjusted by the tension adjustment mechanism 37. Therefore, tension is applied to the cover 16 by the tension of the fixed sling 28. The tension applied to the cover 16 can be used to prevent the cover 16 from deflecting due to the wind pressure generated during lifting. Compared with the example disclosed in Embodiment 1, the number of fastening connections of the first fixing member 27 can be reduced. Moreover, compared with the example disclosed in Embodiment 1, the number of fixed slings 28 can be reduced. Therefore, since the number of parts can be reduced compared to the example disclosed in Embodiment 1, the ease of installation and maintainability are improved.
