The apron 10 is formed by a plate-like member. Apron 10 has a first side 16 and a second side 17 . In this example, the first side 16 and the second side 17 are separated by a fold 18 . The bent portion 18 is a fold along the left-right direction. The angle of fold at fold 18 is less than a right angle. That is, the angle formed by the first surface 16 and the second surface 17 is an obtuse angle. The first surface 16 is a surface above the bent portion 18 . The first surface 16 is arranged with its surface facing forward along the vertical direction. That is, the first surface 16 is arranged parallel to the inner wall 3 of the hoistway 2 . The second surface 17 is a surface below the bent portion 18 . The second surface 17 is inclined rearward to form an obtuse angle with the first surface 16 . That is, the lower end of the second surface 17 is positioned rearward from the upper end. A first ventilation hole 19 is provided in the second surface 17 . The first ventilation hole 19 is a hole that allows air to pass through. The first ventilation hole 19 may consist of a plurality of holes. At this time, the arrangement of the plurality of holes is not limited to the arrangement shown in FIG. Also, the first ventilation hole 19 may be a slit or the like. A net or the like may be provided in the first ventilation hole 19 .

The guide member 11 is provided below the car room 8. The guide member 11 has a first panel 20 . The first panel 20 is a plate-like member arranged with its surface facing forward along the vertical direction. The first panel 20 is arranged in front of the apron 10 .

2 is a cross-sectional view of the car 6 of the elevator 1 according to Embodiment 1. FIG.
In FIG. 2, a cross section along a vertical plane passing through the center of the car room 8 and perpendicular to the left-right direction is shown.

The first panel 20 is connected to the first surface 16 in front of the apron 10. A lower end of the first panel 20 is positioned below the first surface 16 of the apron 10 . A lower end portion of the first panel 20 is positioned below the bent portion 18 of the apron 10 . The lower end of the first panel 20 is positioned below the first ventilation holes 19 of the apron 10 . The lower edge of the first panel 20 is positioned above the lower edge of the second surface 17 of the apron 10 . The first panel 20 has a structure extending downward from a position above the first ventilation holes 19 forward of the second surface 17 .

Next, the dimensions of the circumference of the car 6 when the guide member 11 is removed will be described with reference to FIGS. 3 and 4. FIG.
3 and 4 are cross-sectional views of the car 6 without the guide member 11. FIG.
In FIGS. 3 and 4, cross-sections taken along a vertical plane passing through the center of the car room 8 and perpendicular to the left-right direction are shown.
The same reference numerals are given to corresponding parts between the car 6 without the guide member 11 and the car 6 according to the first embodiment.

As shown in FIG. 3, the apron 10 is provided below the front end of the car room 8. Apron 10 has a first side 16 and a second side 17 separated by a fold 18 .

As shown in FIG. 4, the spacing A between the first surface 16 of the apron 10 and the inner wall 3 of the hoistway 2 is less than the spacing B between the second surface 17 of the apron 10 and the inner wall 3 of the hoistway 2. . Since the path from below the car 6 to the area C between the car 8 and the inner wall 3 of the hoistway 2 passes between the second surface 17 and the inner wall 3 and between the first surface 16 and the inner wall 3, The path gradually narrows. Region C adjoins the doors provided in cab 8 . In area C, many parts and the like for opening and closing the door are arranged. Therefore, when the flow velocity of the air to the car chamber 8 increases in the area C, the noise generated in front of the car chamber 8 may increase due to the air flow.

Next, an example of noise reduction by the guide member 11 will be described with reference to FIGS. 5A to 5C.
5A is a cross-sectional view of the car 6 without the guide member 11 and without the first ventilation holes 19 in the apron 10. FIG.
5B is a cross-sectional view of car 6 without guide member 11. FIG.
5C is a cross-sectional view of the car 6 according to Embodiment 1. FIG.
5A to 5C show cross-sections taken along a vertical plane passing through the center of the car room 8 and perpendicular to the left-right direction.

Since the apron 10 is provided below the car room 8, the influence of the apron 10 on the noise inside the car room 8 when the car 6 travels upward is small. In Figures 5A to 5C an example of the airflow around cab 8 as car 6 travels downward is shown.

As shown in FIG. 5A, since the front surface of the second surface 17 is inclined and faces downward, the wind from below that hits the front surface of the second surface 17 is It rises along the surface where 19 is not formed. Since the spacing A is less than the spacing B, the apron 10 guides the airflow from below the cab 8 to be collected in the region C between the cab 8 and the inner wall 3 of the hoistway 2 as the car 6 travels downward. be done. As a result, the flow velocity of the air to the cab 8 in region C increases. At this time, the noise generated in front of the car room 8 increases due to the air flow.

As shown in FIG. 5B , when the apron 10 is provided with the first ventilation holes 19 , airflow can pass before and after the first ventilation holes 19 . On the other hand, since the pressure difference before and after the first ventilation hole 19 is small, the amount of airflow passing through the first ventilation hole 19 in the airflow flowing in front of the second surface 17 of the apron 10 is small. Since most of the airflow in front of the second surface 17 of the apron 10 flows into the region C, the noise generated in front of the car room 8 by the airflow may not be sufficiently suppressed.

On the other hand, as shown in FIG. 5C, when the first panel 20 is provided as the guide member 11, the first panel 20 protrudes downward from the bent portion 18 of the apron 10, so that the airflow from below the car 6 is blocked. A region D between the first panel 20 and the second surface 17 is guided. In the area D, the first panel 20 blocks the upward wind along the second surface 17 from flowing to the area C ahead. The area D is located on the air inlet side of the first ventilation hole 19, that is, on the front side, and is a space that is open downward and closed upward. As a result of the inflow of wind into such region D from below, the pressure in region D increases. At this time, since the pressure difference before and after the first ventilation hole 19 increases, an air current flowing rearward from the region D through the first ventilation hole 19 is likely to occur. As a result, the amount of airflow flowing into the area C is reduced, so the flow velocity of the air in the area C is suppressed. Therefore, the noise generated in front of the car room 8 due to the air flow can be suppressed.

As described above, the elevator 1 according to Embodiment 1 includes the car 6 that runs vertically in the hoistway 2 . The car 6 includes a car room 8 , an apron 10 and a guide member 11 . A doorway 12 is provided in front of the car room 8 . An apron 10 is provided below the front end of the cab 8 . Apron 10 has a first surface 16 and a second surface 17 below first surface 16 . The first surface 16 faces forward along the vertical direction. The second surface 17 inclines rearward to form an obtuse angle with the first surface 16 . A first ventilation hole 19 is provided in the second surface 17 . The guide member 11 is provided below the car room 8 . When the car 6 travels downward, the guide member 11 increases the pressure difference between the front and rear of the first ventilation holes 19 by blocking part of the upward airflow. By increasing the pressure difference between the front and rear of the first ventilation holes 19 , the guide member 11 guides the air so that more of the upwardly flowing air flows through the first ventilation holes 19 . In Embodiment 1, the guide member 11 has a structure that prevents the wind from rising above the first ventilation holes 19 on the front side of the second surface 17, and the pressure on the front side of the first ventilation holes 19 to raise
As an example, the guide member 11 has a first panel 20 . The first panel 20 is a plate-shaped member arranged facing forward along the vertical direction. A first panel 20 is connected to the first surface 16 at the front of the apron 10 . The lower edge of the first panel 20 is positioned below the first surface 16 and above the lower edge of the second surface 17 .

With such a configuration, the guide member 11 with the first panel 20 guides the airflow that has not yet passed through the first ventilation holes 19 as the car 6 travels downward, thereby Create a pressure difference between the front and back. As a result, the amount of airflow flowing from below the car room 8 into the area C between the car room 8 and the inner wall 3 of the hoistway 2 is reduced, so that the noise generated in front of the car room 8 due to the air flow is suppressed. become. Therefore, users in the car room 8 are less likely to feel unpleasant noise. Thereby, the comfort in the car room 8 is further enhanced.

In each of the embodiments described below, the points that differ from the examples disclosed in other embodiments will be described in detail. For features not described in each of the following embodiments, any feature disclosed in other embodiments may be employed.

Embodiment 2.
FIG. 6 is a perspective view of the elevator 1 according to Embodiment 2. FIG.

The car 6 of the elevator 1 is provided with a guide member 11. The guide member 11 has a first panel 20 . A lower end portion of the first panel 20 is folded back.

7 is a cross-sectional view of the car 6 of the elevator 1 according to Embodiment 2. FIG.
In FIG. 7, a cross section along a vertical plane passing through the center of the car room 8 and perpendicular to the left-right direction is shown.

In this example, the lower end of the first panel 20 has a hairpin bending shape with a bending angle of about 180°. The bending angle at the lower end of the first panel 20 may be less than 180°.

Next, an example of noise reduction by the guide member 11 will be described with reference to FIG.
FIG. 8 is a cross-sectional view of the car 6 according to Embodiment 2. FIG.
In FIG. 8, a cross section along a vertical plane passing through the center of the car room 8 and perpendicular to the left-right direction is shown.
Also, in FIG. 8, an enlarged area of the lower end portion of the first panel 20 is shown. On the left side of the enlarged area, the first panel 20 is shown with its bottom edge not folded back. On the other hand, on the right side of the enlarged area, the first panel 20 according to Embodiment 2 is shown with its lower end folded back.

When the lower end of the first panel 20 is not folded backward, the radius of curvature of the lower end of the first panel 20 is about the thickness of the first panel 20 . If the lower end of the first panel 20 has such an edge-like shape with a small radius of curvature, the airflow hitting the lower end of the first panel 20 is likely to separate in front of the first panel 20 . When the airflow separates, the effective cross-sectional area as an air passage between the car room 8 and the inner wall 3 of the hoistway 2 becomes smaller, so the flow velocity in the region C between the car room 8 and the inner wall 3 of the hoistway 2 increases. . At this time, the effect of suppressing noise generated in front of the car room 8 may be weakened by the air flow.

On the other hand, by folding the lower end of the first panel 20 backward, the radius of curvature of the lower end of the first panel 20 becomes larger than the plate thickness of the first panel 20 . As a result, separation of the airflow hitting the lower end of the first panel 20 in front of the first panel 20 is suppressed. As a result, the flow velocity of the air in the area C is suppressed, so that the noise generated in front of the car chamber 8 due to the air flow is suppressed.

In addition, since there is no edge-like portion at the lower end of the first panel 20 due to the folding, work such as installation or maintenance inspection can be easily performed.

Embodiment 3.
9 is a cross-sectional view of the car 6 of the elevator 1 according to Embodiment 3. FIG.
In FIG. 9, a cross section along a vertical plane passing through the center of the car room 8 and perpendicular to the left-right direction is shown.

The car 6 of the elevator 1 is provided with a guide member 11. In this example the guide member 11 does not have the first panel 20 . The guide member 11 has a gas permeable member 21 . The gas-permeable member 21 is a member that includes therein a gap that allows gas to pass therethrough. The gas permeable member 21 is, for example, a brush or a porous body having continuous voids. A gas permeable member 21 is provided on the second surface 17 of the apron 10 . The gas permeable member 21 is attached so as to protrude forward from the second surface 17 . The gas permeable member 21 is arranged above the first ventilation holes 19 . In this example, the gas permeable member 21 is positioned adjacent to the upper edge of the first vent 19 .

When the gas permeable member 21 is provided as the guide member 11 , the gas permeable member 21 protrudes forward from the second surface 17 , so that airflow from below the car 6 flows between the gas permeable member 21 and the second surface 17 . You are guided to area E. As with the first panel 20 described in Embodiment 1, the guide member 11 has a structure that prevents the wind from rising above the first ventilation holes 19 on the front side of the second surface 17. . This causes the pressure in region E to increase. At this time, since the pressure difference before and after the first ventilation hole 19 increases, an air current flowing rearward from the region E through the first ventilation hole 19 is likely to occur. As a result, the amount of airflow flowing into the area C is reduced, so the flow velocity of the air in the area C is suppressed. Therefore, the noise generated in front of the car room 8 due to the air flow can be suppressed. Also, part of the airflow flowing into the region C passes through the inside of the gas permeable member 21 . Since the airflow passing through the inside of the gas permeable member 21 is rectified, the noise generated in front of the car chamber 8 due to the airflow can be more effectively suppressed.

Embodiment 4.
FIG. 10 is a perspective view of the elevator 1 according to Embodiment 4. FIG.

The car 6 of the elevator 1 is provided with a guide member 11. The guide member 11 has a second panel 22 . The second panel 22 is a plate-like member that covers at least a portion of the lower surface of the car room 8 from below. The second panel 22 has a trapezoidal shape with an open upper surface when viewed from the front-rear direction. In this example, the bottom surface of the second panel 22 is arranged horizontally. Each of the left and right side surfaces of the second panel 22 is inclined upward to form an obtuse angle with the bottom surface. The front end of the bottom surface of the second panel 22 is joined to the second surface 17 of the apron 10 below the first ventilation holes 19 . In this example, the front edge of the bottom surface of the second panel 22 is connected to the bottom edge of the second surface 17 . The second panel 22 has guide vanes 23 . The guide vane 23 is a plate-like portion arranged along the vertical direction with its surface facing forward. The guide vanes 23 protrude downward from the front end of the bottom surface of the second panel 22 .

Next, an example of noise reduction by the guide member 11 will be described with reference to FIG.
11 is a cross-sectional view of the car 6 of the elevator 1 according to Embodiment 4. FIG.
In FIG. 11, a cross section along a vertical plane passing through the center of the car room 8 and perpendicular to the left-right direction is shown.

When the second panel 22 is provided as the guide member 11, the second panel 22 covers the lower surface of the car chamber 8 from below, so that the airflow from below the car 6 is guided to the side surface of the car chamber 8. Become. This reduces the amount of airflow entering the region F between the second panel 22 and the lower surface of the cab 8 . In addition, the area behind the region F is open toward the inside of the hoistway 2 with a much larger area than the first ventilation hole 19 . For this reason, without the second panel 22, the airflow from below collides with the lower surface of the car chamber 8 and the pressure increases. The pressure in region F behind 22 hardly rises. In addition, although the area F has an opening toward the inside of the hoistway 2, the opening does not face downward, so the wind from below flows into this opening and the pressure in the area F does not rise. . On the other hand, the front surface of the second panel 22, which is inclined downward, receives the wind from below and the pressure rises. As a result, the pressure difference between the front and rear of the first ventilation holes 19 increases, so that an air current flowing from the front to the region F through the first ventilation holes 19 is likely to occur. As a result, the amount of airflow flowing into the area C is reduced, so the flow velocity of the air in the area C is suppressed. Therefore, the noise generated in front of the car room 8 due to the air flow can be suppressed. The wind that has passed through the first ventilation holes 19 can flow out from the rear of the region F or the like, and can flow upward from the rear of the car room 8 .

As explained above, the guide member 11 of the elevator 1 according to Embodiment 4 has the second panel 22 . The second panel 22 is a plate-like member that covers the lower surface of the car room 8 from below. The front end of the bottom surface of the second panel 22 is connected to the rear of the apron 10 below the first ventilation holes 19 of the second surface 17 .

With such a configuration, the guide member 11 having the second panel 22 directs the airflow that does not pass through the first ventilation holes 19 when the car 6 travels downward to the upper car room while avoiding the rear of the second panel 22 . By guiding to the side surface of 8, the pressure difference before and after the first ventilation hole 19 is increased. As a result, the amount of airflow flowing from below the car room 8 into the area C between the car room 8 and the inner wall 3 of the hoistway 2 is reduced, so that the noise generated in front of the car room 8 due to the air flow is suppressed. become. Therefore, users in the car room 8 are less likely to feel unpleasant noise. Thereby, the comfort in the car room 8 is further enhanced. The guide member 11 of the fourth embodiment is similar to that of the first embodiment in that the pressure difference between the front and rear of the first ventilation hole 19 is increased by blocking part of the upwardly flowing air. The second panel 22 that constitutes the guide member 11 of Embodiment 4 has a structure that prevents the wind from rising below the first ventilation holes 19 on the rear surface side of the second surface 17. It prevents the pressure on the rear surface side of the hole 19 from rising.

The second panel 22 may be made of a flat plate. However, as shown in the trapezoidal shape in the figure, the front is not bent upward, and the lateral ends are directed upward from the center. preferably have a curved shape. Such a shape is preferable because it directs the wind from below up through the sides of the cab 8 instead of the front, reducing the wind flowing into region C.

The second panel 22 also has a plate-like guide vane 23 below the front end of the bottom surface. The guide vanes 23 are arranged facing forward along the vertical direction.

With such a configuration, the guide vanes 23 suppress the flow of the airflow that hits the bottom surface of the second panel 22 from below into the region C. As a result, the noise generated in front of the car room 8 due to the air flow can be more effectively suppressed.

In addition, in the second panel 22, the rear of the bottom surface and the like may be bent upward. Alternatively, the bottom surface of the second panel 22 may be tilted upward toward the rear. This makes it easier for the airflow to be guided to the rear of the car 6, so that the pressure difference between the front and rear of the first ventilation holes 19 is increased.

Also, the guide member 11 may include the first panel 20 and the gas permeable member 21 in combination with the second panel 22 .

Embodiment 5.
12 is a cross-sectional view of the car 6 of the elevator 1 according to Embodiment 5. FIG.
In FIG. 12, a cross section along a vertical plane passing through the center of the car room 8 and perpendicular to the left-right direction is shown.

A second ventilation hole 24 is provided at the rear portion of the bottom surface of the second panel 22 . The second ventilation hole 24 is a hole that allows air to pass through. The second ventilation hole 24 may consist of a plurality of holes. At this time, the arrangement of the plurality of holes is not limited to the arrangement shown in FIG. Also, the second ventilation hole 24 may be a slit or the like. A net or the like may be provided in the second ventilation holes 24 .

The airflow that strikes the bottom surface of the second panel 22 from below passes through the second ventilation holes 24, which promotes the flow of the airflow to the rear of the car room 8. The pressure in the region G between the lower surfaces is lower. At this time, since the pressure difference before and after the first ventilation hole 19 becomes larger, an air current flowing from the front to the region G through the first ventilation hole 19 is likely to occur. As a result, the amount of airflow flowing into the area C is reduced, so the flow velocity of the air in the area C is suppressed. Therefore, the noise generated in front of the car room 8 due to the air flow can be suppressed.

14 is a cross-sectional view of the car 6 of the elevator 1 according to Embodiment 6. FIG.
In FIG. 14, a cross section along a vertical plane passing through the center of the car room 8 and perpendicular to the left-right direction is shown.

A side slit 26 is provided in each side panel 25 . The side slits 26 are slits along the front-rear direction. The rear side of the side slit 26 is notched. As a result, the side slits 26 are opened rearward. The height of the upper end of the side slit 26 provided in the left side panel 25 is provided according to the height of the left end of the second panel 22 . The height of the upper end of the side slit 26 provided in the right side panel 25 is provided according to the height of the right end of the second panel 22 . In this example, the upper end of the side slit 26 provided in the left side panel 25 is connected to the left end of the second panel 22 . Also, the upper end of the side slit 26 provided in the right side panel 25 is connected to the right end of the second panel 22 .

Next, an example of noise reduction by the guide member 11 will be described with reference to FIGS. 15A and 15B.
15A is a perspective view of elevator 1 without side panels 25 on car 6. FIG.
15B is a perspective view of the elevator 1 according to Embodiment 6. FIG.

As shown in FIG. 15A , part of the airflow that hits the bottom surface of the second panel 22 from below passes through the side surface of the second panel 22 and the laterally outer side of the apron 10 to reach the inner wall 3 of the cage 8 and the hoistway 2 . may flow into region C between When a part of such airflow flows, the flow velocity in region C increases. At this time, the effect of suppressing noise generated in front of the car room 8 may be weakened by the air flow.

On the other hand, as shown in FIG. 15B , the provision of the pair of side panels 25 suppresses the inflow of air into the area C through the side surface of the second panel 22 or the outside of the apron 10 in the left-right direction. . In addition, since the side panel 25 is provided with the side slit 26 , the airflow that hits the second panel 22 from below is guided through the side slit 26 so as to pass through the side of the car room 8 . Since the side slits 26 are open rearward, the airflow passing through the side slits 26 is less likely to flow into the front region C of the car chamber 8 . Since the height of the side slits 26 is provided according to the height of the left and right ends of the second panel 22, the air currents hitting the second panel 22 from below are more effectively guided to the side slits 26. become. This reduces the inflow of air into the area between the second panel 22 and the lower surface of the car room 8, thereby lowering the pressure in that area. Therefore, the pressure difference before and after the first ventilation hole 19 increases, so that the inflow of air into the region C is further suppressed. As a result, the noise generated in front of the car room 8 due to the air flow can be more effectively suppressed.
