The support base 18 is arranged on the upper beam 14 . A support base 18 is fixed to the upper beam 14 .

The first pipe 19 has a first bar-shaped portion 21 and a first bent portion 22 . The first bar-shaped portion 21 extends from the end on the door 6 side along the y-axis so as to move away from the door 6 . The first rod-shaped portion 21 is arranged on the upper beam 14 . The first bar-shaped portion 21 is supported by the upper beam 14 .

The end of the second bar-shaped portion 23 is the left end when viewed from the door 6 side. The third bent portion 25 curves downward from the other end of the second rod-shaped portion 23 toward the car chamber 5 and extends along the vertical direction. The end of the second bar-shaped portion 23 is the right end as viewed from the door 6 side. A second pipe 20 is arranged above the first pipe 19 . A second pipe 20 is fixed to the first pipe 19 . A gap is formed between the end of the second pipe 20 on the side of the second bent portion 24 and the car chamber 5 . A space is formed between the end of the second pipe 20 on the side of the third bent portion 25 and the car chamber 5 .

The second pipe 20 is arranged above the first pipe 19 means that the distance between the second rod-shaped portion 23 and the cage 5 on the vertical projection plane is the distance between the first rod-shaped portion 21 and the cage 5. is arranged so as to be longer than the distance of That is, the second rod-shaped portion 23 of the second pipe 20 is farther from the car chamber 5 than the first rod-shaped portion 21 of the first pipe 19 on the vertical projection plane.

As shown in FIG. 4, the first rod-shaped portion 21 of the first pipe 19 intersects the upper beam 14 on the horizontal projection plane. The main rope 3 is connected to the central portion of the upper beam 14 . The second rod-shaped portion 23 of the second pipe 20 intersects with the first pipe 19 on the horizontal projection plane.

Next, the positions of the first pipe 19 and the second pipe 20 will be explained. In the specific example shown in FIG. 4 , the framework of the air rectifier 8 comprises two supports 18 , two first pipes 19 and three second pipes 20 . When it is necessary to specify the two support bases 18 below, reference numerals 18a to 18b are attached to the support bases 18 as shown in FIG. Similarly, the first pipe 19 is denoted by reference numerals 19a-19b. Furthermore, the second pipe 20 is denoted by reference numerals 20a to 20c. Further, the constituent elements of the first pipe 19a are identified by adding the letter a after the reference numerals. Similarly, the constituent elements of the first pipe 19b are identified by adding the letter b after the reference numerals. The constituent elements of the second pipe 20a are identified by adding the letter a after the reference numerals. The constituent elements of the second pipe 20b are identified by adding the letter b after the reference numerals. The constituent elements of the second pipe 20c are identified by adding the letter c after the reference numerals.

The support base 18a is arranged on the left side of the main rope 3 when viewed from the door 6 side on the horizontal projection plane. The support base 18a is installed within the area of the car room 5 on the plane of horizontal projection. The support base 18b is arranged on the right side of the main rope 3 when viewed from the door 6 side on the horizontal projection plane. The support base 18b is installed in the region of the car room 5 on the plane of horizontal projection.

The first pipe 19a is arranged on the support base 18a. The first bar-shaped portion 21a of the first pipe 19a is fixed to the support base 18a. The first pipe 19 a is fixed at the intersection with the upper beam 14 . The first pipe 19b is arranged on the support base 18b. A first bar-shaped portion 21b of the first pipe 19b is fixed to the support base 18b. The first pipe 19b is fixed at the intersection with the upper beam 14. As shown in FIG. The first pipe 19a and the first pipe 19b are arranged at the same height.

The second pipe 20a is arranged on the end of the first bar-shaped portion 21a on the door 6 side. The second pipe 20a is arranged on the end of the first rod-shaped portion 21b on the door 6 side. The second pipe 20a intersects the first pipe 19a on the horizontal projection plane. The second pipe 20a intersects the first pipe 19b on the horizontal projection plane. The second pipe 20a is fixed to the first pipe 19a at the intersection with the first pipe 19a. The second pipe 20a is fixed to the first pipe 19b at the intersection with the first pipe 19b. The second pipe 20b is arranged between the second pipe 20a and the

support bases

18a and 18b on the horizontal projection plane. The second pipe 20b intersects the first pipe 19a on the horizontal projection plane. The second pipe 20a intersects the first pipe 19b on the horizontal projection plane. The second pipe 20b is fixed to the first pipe 19a at the intersection with the first pipe 19a. The second pipe 20b is fixed to the first pipe 19b at the intersection with the first pipe 19b. The second pipe 20c is arranged so as to be closer to the first bent portion 22a and the first bent portion 22b than the connection point between the main rope 3 and the upper beam 14 on the horizontal projection plane. 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 20b is fixed to the first pipe 19a at the intersection with the first pipe 19a. The second pipe 20b is fixed to the first pipe 19b at the intersection with the first pipe 19b.

A circular aerial pipe is used as the material of the first pipe 19 and the second pipe 20 . A square tube with edges can also be used, but since there is a possibility that the soft material cover 16 may be punctured or torn, it is preferable to use a round tube without edges.

The first pipe 19 has the role of connecting the support base 18 and the second pipe 20 . The shape of the first bent portion 22 plays a role in determining the shape of the cover 16 in the y-axis direction. The shapes of the second bent portion 24 and the third bent portion 25 play a role in determining the shape of the cover 16 in the x-axis direction. Therefore, the shape of the cover 16 can be determined by two types of parts, the first pipe 19 and the second pipe 20 . Therefore, it is possible to reduce the number of types of parts and improve the ease of installation. Furthermore, the structure becomes simple and the assembly work becomes easy.

Next, the cover 16 will be explained using FIG. FIG. 5 is a side view of the car 1 of the elevator.

The cover 16 has a shape that follows the framework inside the air rectifier 8 . The cover 16 is installed so as to cover the first pipe 19 and the second pipe 20 from the outside. An opening is formed in the lower portion of the cover 16 . A recessed notch is formed in the side surface of the cover 16 along the x-axis direction. One notch is formed on the side surface of the right cover 16 and the other on the left side surface of the cover 16 as viewed from the door 6 . The notch has a depth that does not allow the cover 16 to overlap the car frame 7 . An upper beam 14 passes through the notch. The cover 16 has at least eight connecting portions 26 at each of the lower corners of the notch and the ends of the corners on the horizontal projection plane.

As the material of the cover 16, a soft material such as a cloth material, a resin material, or a paper material that can follow the shape of the framework inside the air conditioning device 8 is used. If a metal plate is used as the material of the cover 16, a plurality of sheet metal parts and parts such as bolts are required. Furthermore, sheet metal parts require bending. Therefore, the production cost is high and the assembly work takes time. The use of soft materials eliminates the need for sheet metal parts and bending. Also, the number of parts such as bolts can be reduced compared to when metal plates are used. Therefore, by using the cover 16 made of a soft material, the cost can be reduced and the ease of installation and maintenance can be improved as compared with the case of using a metal plate.

Next, the cover fixing portion 9 will be described with reference to FIGS. 5 and 6 as well. FIG. 6 is a front view of the car 1 of the elevator.

The cover fixing part 9 is provided on the upper part of the cover 16 and the lower part of the cover 16 . The cover fixing part 9 on the top of the cover 16 comprises a first fixing part 27 such as a bolt. The cover 16 overlaps the second pipe 20b on the horizontal projection plane. The cover 16 overlaps the second pipe 20c on the horizontal projection plane. The cover fixing portion 9 is provided at a location where the cover 16 and the second pipe 20b overlap. The cover fixing portion 9 is provided at a location where the cover 16 and the second pipe 20c overlap. The cover 16 is fixed from above by a first fixing part 27 . The cover 16 is fixed to the second pipe 20b. The cover 16 is fixed to the second pipe 20c. The first fixing component 27 is arranged closer to the upper beam 14 than the second pipe 20a on the horizontal projection plane.

Next, the cover fixing portion 9 at the bottom of the cover 16 will be described with reference to FIGS. 5 and 6 as well.

　In the examples shown in FIGS. 5 and 6, the car 1 is provided with a fixed rope 28. The cover fixing part 9 comprises a second fixing part 29 . One side of the fixed rope 28 is connected to the connecting portion 26 of the cover 16 . The second fixing part 29 is hook-shaped. A second fixed part 29 is fixed to the car frame 7 . The other side of the fixed rope 28 is fastened to the second fixed part 29 . Thus, the cover lower portion is fixed to the car 1 under tension. A space is formed between the lower edge of the cover 16 and the car chamber 5 .

Next, the superiority of the position of the cover 16 will be explained. When the car room 5 is arranged at the height of the landing, the door 6 is arranged at a position closer to the landing than the cover 16 on the horizontal projection plane. Therefore, a space is formed between the cover 16 and the equipment in the hoistway on the horizontal projection plane. Therefore, interference between the cover 16 and equipment in the hoistway can be prevented.

Next, the superiority of the position of the cover fixing portion 9 will be explained. Cover 16 includes surface 30 . The surface 30 is a surface facing a door provided at the landing when the car 1 is raised and lowered. Door 6 comprises a face 31 . The surface 31 is a surface facing a door provided at the landing when the car 1 is raised and lowered. The plane 31 is the plane of the door 6 that is farthest from the car frame 7 on the plane of horizontal projection. The surface 30 is installed closer to the upper beam 14 than the surface 31 on the horizontal projection plane. The surface 30 is closest to the equipment in the hoistway among the surfaces provided by the cover 16 . In order to prevent interference between the cover 16 and equipment in the hoistway, the surface 30 should have a small deflection. The cover fixing portion 9 is installed closer to the upper beam 14 than the second pipe 20a on the horizontal projection plane. Therefore, tension is generated in the surface 30, making it difficult to bend. Also, by using tension to fix the cover 16, the number of fixing points of the cover 16 can be reduced. Therefore, the number of parts can be reduced, and the installability is improved.

Next, the shape of the air rectifier 8 will be described. The noise generated during lifting and lowering tends to flow into the car room 5 through the gap between the car room 5 and the door 6. - 特許庁In order to suppress noise, it is necessary to reduce the amount of air flowing toward the door 6 side. The shape of the air conditioner 8 is determined by the shape of the first pipe 19 and the shape of 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 bent portion 24 and a third bent portion 25 . Due to the shape of the first pipe 19 and the shape of the second pipe 20, the cover 16 of the air rectifier 8 has a curved upper part of the side surface other than the surface 30 and has a streamline shape. Therefore, the air near the surface of the cover 16 when the car 1 rises tends to flow along surfaces other than the surface 30 . Therefore, air flowing along the surface 30 can be suppressed. Therefore, the air rectifier 8 can reduce the flow rate of the air flowing toward the door 6 side. Thereby, the noise in the car room 5 can be reduced.

Next, the superiority of the positional relationship between the first pipe 19 and the second pipe 20 during assembly will be described. The car frame 7 is one of the strongest parts of the car 1 . Therefore, the air conditioner 8 is attached to the car frame 7 . The framework of the air conditioning device 8 comprises a support base 18, a first pipe 19 and a second pipe 20. A support base 18 is fixed to the upper beam 14 . The first pipe 19 is arranged on the support base 18 . The first pipe 19 is arranged along the y-axis on the plane of horizontal projection. Therefore, the first pipe 19 intersects the upper beam 14 on the horizontal projection plane. Therefore, the first pipe 19 can be fixed to the support base 18 at the intersection with the upper beam 14 . A second pipe 20 is arranged above the first pipe 19 . The second pipe 20 is arranged along the x-axis on the plane of horizontal projection. Therefore, the second pipe 20 intersects the first pipe 19 on the horizontal projection plane. Therefore, the second pipe 20 can be fixed to the first pipe 19 at the point of intersection with the first pipe 19 . On the other hand, the second pipe 20 does not cross the upper beam 14 . Thus, if the second pipe 20 is mounted below the first pipe 19, additional fixing parts are required. Therefore, the framework in which the second pipe 20 is arranged above the first pipe 19 can reduce the number of parts compared to the framework in which the second pipe 20 is arranged below the first pipe 19, and the installation is improved. Furthermore, the structure becomes simple and the assembly work becomes easy.

Next, the superiority of the positional relationship between the first pipe 19 and the second pipe 20 when the car 1 is raised and lowered will be described with reference to FIG.

FIG. 7 is a central cross-sectional view of the elevator car 1 showing the relationship between the airflow during ascent and the shape of the cover 16. FIG.

The second pipe 20 is arranged above the first pipe 19, as shown in FIG. When the car 1 rises, a downward airflow A is generated. Due to the downward pressure generated by the airflow A, the upper portion of the cover 16 bends along the x-axis direction between the

second pipes

20a and 20b and between the

second pipes

20b and 20c. As a result, the bent portion acts like a groove. Therefore, in the vicinity of the upper surface of the cover 16, the airflow B in the x-axis direction is likely to occur, and the airflow C in the y-axis direction is less likely to occur. Therefore, it is possible to reduce the airflow C generated toward the door 6, which is a cause of noise. On the other hand, if the heights of the first pipe 19 and the second pipe 20 are the same, the upper portion of the cover 16 bends in a rectangular shape along the x-axis direction and the y-axis direction. Therefore, near the surface of the upper portion of the cover 16, the airflow B and the airflow C are generated to the same degree. Therefore, a state in which the airflow C in the y-axis direction is difficult to generate is not created. Also, when the first pipe 19 is arranged on the second pipe 20, the upper portion of the cover 16 bends along the y-axis direction between the first pipe 19a and the first pipe 19b. Therefore, in the vicinity of the upper surface of the cover 16, the airflow C in the y-axis direction is likely to occur, and the airflow B in the x-axis direction is less likely to occur. Therefore, a state in which the airflow C in the y-axis direction is difficult to generate is not created. Thus, by arranging the second pipe 20 on the first pipe 19, the flow rate of the air flowing toward the door 6 can be suppressed. Thereby, the noise in the car room 5 can be reduced.

2 to 7 show an example in which the air rectifier 8 is provided with two first pipes 19 and three second pipes 20. FIG. As another example, the air conditioner 8 may have only one first pipe 19 and only one second pipe 20 . In addition, when the car 1 is raised, in order to create a structure in which the airflow B in the x-axis direction is likely to occur near the upper surface of the cover 16, the air rectifier 8 includes a plurality of first pipes 19 and a plurality of second pipes 19. Preferably, a pipe 20 is provided. For example, the air conditioner 8 may comprise two first pipes 19 and two second pipes 20 .

2 to 7 describe the structure of the framework in which the support 18 is installed between the upper beam 14 and the first pipe 19. 19 may be fixed.

Note that the air rectifier 8 may be installed under the car room 5. Also, the air rectifier 8 may be installed both above and below the car room 5 . When the air conditioner 8 is installed under the car room 5, the air conditioner 8 is installed upside down. Also, the support base 18 or the first pipe 19 is fixed under the lower beam 15 . By installing the air rectifier 8 under the car room 5, noise when the car 1 descends can be suppressed.

According to Embodiment 1 described above, the air conditioner 8 includes the cover 16 and the framework. The shape of the framework of the air conditioner 8 is determined by the shapes of the first pipe 19 and the second pipe 20 . The first pipe 19 intersects the second pipe 20 on the horizontal projection plane. The frame of the air rectifier 8 is made by crossing two kinds of parts. Therefore, the number of kinds of parts is reduced, and the ease of installation is improved. Furthermore, the structure becomes simple and the assembly work becomes easy.

The first pipe 19 is arranged below the second pipe 20. The first pipes 19 intersect on the plane of horizontal projection. The second pipe 20 crosses the first pipe 19 on the horizontal projection plane. Therefore, the first pipe 19 can be fixed at the intersection with the upper beam 14 or the support base 18 . Also, the second pipe 20 can be fixed at the intersection with the first pipe 19 . Therefore, the number of parts required for fixing can be reduced. This further improves the installability and facilitates the assembly work.

The first pipe 19 has a first bar-shaped portion 21 and a first bent portion 22 . The second pipe 20 has a second rod-shaped portion 23 , a second bent portion 24 and a third bent portion 25 . As a result, it is possible to suppress the airflow generated toward the door 6, which causes noise.

The first pipe 19 is arranged below the second pipe 20. Therefore, an airflow is likely to occur in the x-axis direction, and an airflow is less likely to occur in the y-axis direction. As a result, the airflow generated toward the door 6, which causes noise, can be further suppressed.

The cover 16 is fixed by the cover fixing portion 9 . Therefore, tension is applied to the cover 16, and deflection can be prevented. Therefore, the air rectifier 8 can reduce the fixing parts of the cover 16 . This further improves the installability and facilitates the assembly work.

When the car room 5 is arranged according to the height of the landing, the door 6 is arranged at a position closer to the landing than the cover 16 on the horizontal projection plane. Thereby, interference between the cover 16 and equipment in the hoistway can be prevented.

A soft material is used for the cover 16 . Since it can follow the framework of the air rectifier 8, there is no need to perform bending or the like at the time of manufacture. Also, the cover 16 can be folded. Therefore, transportation of the cover 16 is facilitated. Furthermore, the cover 16 can be unfolded over the car 1 from a folded state and attached to the framework. This improves portability and installability, and facilitates assembly work.

Embodiment 2.
FIG. 8 is a perspective view of the cover 16 of soft material attached to the framework of the air conditioner 8. FIG. The same reference numerals are given to the same or corresponding parts as those of the first embodiment. Description of this part is omitted.

As shown in FIG. 8 , in Embodiment 2, the cover 16 has an opening/closing mechanism 32 that can be opened and closed on a line that connects the rope hole 17 and the end of the cover 16 . The opening/closing mechanism 32 is a mechanism capable of opening and closing the cover 16 . The opening/closing mechanism 32 uses, for example, fasteners, buttons, and bolts. An opening/closing mechanism 32 is provided on the surface 30 . The opening/closing mechanism 32 is closed when the elevator system is in operation. Therefore, the air rectifying device 8 can maintain the air rectifying function during operation of the elevator device.
