The hanger 4e is connected to a drive device (not shown). The hanger 4e is driven by the drive device.

[0063] The elevator cab 3 in the first embodiment is provided as described above.

[0064] When the car floor movable part 13 is in the installed state, the wall panel 25 is prevented from moving downward by the car floor movable part 13.

[0065] When the car floor movable part 13 is in a moving state, the wall panel 25 can move downward without being hindered by the car floor movable part 13.

[0066] The wall panel 25 can be attached and detached by moving the car floor movable part 13 in the moving state and moving the wall panel 25 in the up and down direction. When attaching and detaching the wall panel 25, when the wall panel 25 is positioned below the mounting part 4b of the car door opening and closing device 4, the wall panel 25 can be moved in the left and right direction.

[0067] The method for removing the wall panel 25 in the first embodiment includes steps S11 to S13 shown in FIG.

[0068] In step S11 (car floor movable part moving step), the car floor movable part 13 is put into a moving state. When the car floor movable part 13 is in an installed state, the screw member 10g joining the car floor movable part 13 to the wall panel 25 and the screw members 14a, 14b, and 14c joining the car floor movable part 13 to the car floor fixed part 12 are removed. Furthermore, when the car floor movable part 13 is moved, the car floor movable part 13 separates from the wall panel 25, and the car floor movable part 13 can be put into a moving state.

[0069] In step S12 (wall panel separation step), the wall panel 25 is separated from the car ceiling 9 and the car walls 10. The screw members 10g joining the wall panel 25 to the car ceiling 9, the wall panel 24, and the upper panel 26 are removed. The wall panel 25 is separated from the car ceiling 9 and the car walls 10, and becomes movable relative to the car ceiling 9 and the car walls 10.

[0070] In step S13 (wall panel removal step), the wall panel 25 is removed by moving it downward. When the wall panel 25 is positioned below the mounting portion 4b of the car door opening and closing device 4, the wall panel 25 can be moved to the outside of the car 1 in the left-right direction.

[0071] According to steps S11 to S13, the car floor movable part 13 is changed from the installed state to the movable state, and the wall panel 25 is moved downward, whereby the wall panel 25 can be removed.

[0072] The method of installing the wall panel 25 in the first embodiment is performed in the reverse order to the method of removing the wall panel 25 in the first embodiment.

[0073] In embodiment 1, the elevator car room 3 comprises a car floor 8, a car ceiling 9, and a car wall 10, the car wall 10 has a wall panel 25, the car floor 8 has a car floor fixed part 12 and a car floor movable part 13, the car floor movable part 13 is arranged to be movable relative to the car floor fixed part 12 and changes between an installed state in which the wall panel 25 is sandwiched between the car ceiling 9 and the car floor movable part 13 in the vertical direction, and a movable state in which the wall panel 25 is moved away from the car floor movable part 13, and when the car floor movable part 13 changes from the installed state to the movable state, the wall panel 25 can move downward.

[0074] As a result, when removing the wall panel 25, the car floor movable part 13 is changed from the installed state to the movable state, and the wall panel 25 is moved downward, thereby making it possible to remove the wall panel 25. When attaching the wall panel 25, the car floor movable part 13 is put into the movable state, and the wall panel 25 is moved upward, thereby making it possible to attach the wall panel 25. Therefore, the wall panel 25 can be detached without moving the car ceiling 9.

[0075] In the elevator car room 3 in the first embodiment, the car floor movable part 13 is provided detachably with respect to the car floor fixed part 12.

[0076] This allows the wall panel 25 to be more reliably attached and detached without being hindered by the car floor movable part 13.

[0104] The wall panel 25 is sandwiched between the car floor movable part 33 and the car ceiling 9. The wall panel 25 is detachably joined to the car floor movable part 33 by screw members 10g.

[0105] The size of the projection plane of the wall panel 25 and the car operating panel 31 projected perpendicularly onto a horizontal plane is such that it fits within the inside of the projection plane of the floor panel recess 15d and the movable threshold portion 35 projected perpendicularly onto the horizontal plane.

[0106] When the car floor movable part 33 is in a moving state, the car floor movable part 33 and the threshold movable part 35 are in the following states.

[0107] The car floor movable part 33 is not separated from the car floor fixed part 12. The car floor movable part 33 is in a state of being moved downward by rotating about the center line of the shaft part of the screw member 14b and the center line of the shaft part of the screw member 14c. The car floor movable part 33 is located lower than the car floor movable part 33 in the installed state.

[0108] The floor panel 36a does not overlap the floor panel recess 15d. The car floor movable part 33 does not cover the floor panel recess 15d.

[0109] The threshold movable part 35 is in a downwardly moved state by rotating integrally with the car floor movable part 33. The threshold movable part 35 is located lower than the threshold movable part 35 when the car floor movable part 33 is in the installed state. The threshold movable part 35 is not located in front of the floor plate recess 15d. The threshold movable part 35 is farther from the wall panel 25 than the threshold movable part 35 when the car floor movable part 33 is in the installed state.

[0110] The screw member 14a does not join the car floor fixed part 12 to the car floor movable part 33. The screw member 14a does not join the connecting plate 18 to one of the support plates 37.

[0111] The wall panel 25 is not sandwiched between the car floor movable part 33 and the car ceiling 9. The wall panel 25 is not joined to the car floor movable part 33 by the screw members 10g. The car floor movable part 33 is separated from the wall panel 25.

[0112] The elevator cab 3 in the second embodiment is provided as described above.

[0113] When the car floor movable part 33 is in the installed state, the wall panel 25 is prevented from moving downward by the car floor movable part 33.

[0114] When the car floor movable part 33 is in the moving state, the wall panel 25 can move downward without being hindered by the car floor movable part 33. When the car floor movable part 33 is in the moving state, the wall panel 25 can move forward without being hindered by the threshold movable part 35.

[0115] The wall panel 25 can be attached and detached by moving the car floor movable part 33 in the moving state and moving the wall panel 25 in the up and down direction. When attaching and detaching the wall panel 25, the wall panel 25 can be moved forward to separate it from the car floor fixed part 12 and the wall panel 24. When attaching and detaching the wall panel 25, when the wall panel 25 is located below the support body 4a of the car door opening and closing device 4, the wall panel 25 can be moved in the front-rear direction. When attaching and detaching the wall panel 25, when the wall panel 25 is located below the mounting part 4b of the car door opening and closing device 4, the wall panel 25 can be moved in the left-right direction. Therefore, the wall panel 25 can be attached and detached with the car operation panel 31 attached to the wall panel 25.

[0116] The method for removing the wall panel 25 in the second embodiment includes steps S21 to S23 shown in FIG.

[0117] In step S21 (car floor movable part moving step), the car floor movable part 33 is brought into a moving state. When the car floor movable part 33 is in an installed state, the screw member 10g joining the car floor movable part 33 to the wall panel 25 and the screw member 14a joining the car floor movable part 33 to the car floor fixed part 12 are removed, and the screw members 14b and 14c joining the car floor movable part 33 to the car floor fixed part 12 are loosened. Furthermore, when the car floor movable part 33 is moved downward by rotating, the car floor movable part 33 is separated from the wall panel 25, and the car floor movable part 33 can be brought into a moving state. When the car floor movable part 33 is brought into a moving state, the threshold movable part 35 moves downward by rotating integrally with the car floor movable part 33.

[0118] In step S22 (wall panel separation step), the wall panel 25 is separated from the car ceiling 9 and the car walls 10. The screw members 10g joining the wall panel 25 to the car ceiling 9, the wall panel 24, and the upper panel 26 are removed. The wall panel 25 is separated from the car ceiling 9 and the car walls 10, and becomes movable relative to the car ceiling 9 and the car walls 10.

[0119] In step S23 (wall panel removal step), the wall panel 25 is removed by moving it downward and forward. When the wall panel 25 is moved downward to remove it from the car room 3, the wall panel 25 is moved forward to prevent the car operation panel 31 from hitting the car floor fixed portion 12. When the wall panel 25 is located below the mounting portion 4b of the car door opening and closing device 4, the wall panel 25 can be moved left and right to the outside of the passenger car 1. When the wall panel 25 is located below the support body 4a of the car door opening and closing device 4, the wall panel 25 can be moved forward to the outside of the passenger car 1. When the wall panel 25 is moved left and right to the outside of the passenger car 1, the wall panel 25 is moved forward to prevent the car operation panel 31 from hitting the wall panel 24.

[0120] According to steps S21 to S23, the car floor movable section 33 is changed from the installed state to the movable state, and the wall panel 25 is moved downward and forward, whereby the wall panel 25 and the operation panel 31 can be removed.

[0121] The method of installing the wall panel 25 in the second embodiment is performed in the reverse order to the method of removing the wall panel 25 in the second embodiment.

[0122] The elevator car room 3 in the second embodiment is equipped with a car door 11 that opens and closes the car entrance 3a by moving in the width direction of the car entrance 3a, the wall panel 25 forms a wall on the side of the car entrance 3a in the car room 3 and is located on the outside of one side in the width direction of the car entrance 3a, the car floor 8 has a threshold 32 that guides the movement of the car door 11, the threshold 32 has a threshold fixed part 34 and a threshold movable part 35, the threshold fixed part 34 forms the lower end of the car entrance 3a and the threshold The threshold movable part 35 is arranged to be movable relative to the threshold fixed part 34, and when the car floor movable part 33 is in an installed state, the threshold movable part 35 is positioned outside one side of the car entrance / exit 3a in the width direction at the threshold fixed part 34, and the threshold fixed part 34 and the threshold movable part 35 are connected in the width direction of the car entrance / exit 3a, and when the car floor movable part 33 is in a moving state, the threshold movable part 35 is not positioned outside one side of the car entrance / exit 3a in the width direction at the threshold fixed part 34, and is separated from the wall panel 25.

[0123] As a result, when removing the wall panel 25, by changing the car floor movable part 33 from the installed state to the movable state and moving the wall panel 25 downward, the wall panel 25 can be removed more reliably without being hindered by the movable threshold part 35. When attaching the wall panel 25, by putting the car floor movable part 33 into the movable state and moving the wall panel 25 upward, the wall panel 25 can be attached more reliably without being hindered by the movable threshold part 35.

[0124] In the elevator car room 3 in the second embodiment, the threshold movable part 35 moves integrally with the car floor movable part 33.

[0125] This allows the car floor movable part 33 and the threshold movable part 35 to move simultaneously.

[0126] The elevator cab 3 in the second embodiment is equipped with a car operating panel 31 that protrudes from the wall panel 25 to the inside of the cab 3.

[0127] As a result, even if the car operation panel 31 is attached to the wall panel 25 so as to protrude from the wall panel 25 toward the inside of the car room 3, when the wall panel 25 is moved in the vertical direction to attach or detach the wall panel 25, the wall panel 25 can be moved forward to separate the operation panel 31 from the car floor fixed part 12.

[0128] In the elevator car room 3 in the second embodiment, the car floor movable part 33 is provided so as to be movable downward by rotating with respect to the car floor fixed part 12.

[0129] As a result, since the car floor movable part 33 is supported by the car floor fixed part 12, the car floor movable part 33 can be easily changed between the installed state and the moving state.

[0130] Furthermore, since the car floor movable part 33 moves by rotating, the car floor movable part 33 can be moved smoothly.

[0131] In addition, it is possible to prevent the car floor movable part 33 from falling and being damaged.

[0132] In the elevator car room 3 in the second embodiment, the screw members 14b and 14c may be pins. Also, the car floor movable part 33 may be rotatably joined to the car floor fixed part 12 by using a hinge, without using the screw members 14b and 14c.

[0133] In the elevator cab 3 in the second embodiment, as shown in FIG. 19, the movable threshold part 35 and the floor panel 36a may be formed of separate members and detachably joined by screws or the like.

[0134] Fig. 19 is a detailed view of the main parts of the car room 3 in the second embodiment. Fig. 19(a) is a detailed view of the main parts of the car room 3 with the car floor movable part 33 in an installed state. Fig. 19(b) is a detailed view of the main parts of the car room 3 with the car floor movable part 33 in a moving state. Fig. 19 is a drawing corresponding to Fig. 16.

[0135] In the elevator car room 3 in the second embodiment, the screw members 14b and 14c may be provided below the car entrance 3a, and the center line of the shaft of the screw member 14b and the center line of the shaft of the screw member 14c may extend in the depth direction of the car entrance 3a. In this case, when the car floor movable part 33 is in the moving state, the car floor movable part 33 and the threshold movable part 35 are located below the car entrance 3a.

[0136] In addition, in the elevator car room 3 in embodiment 2, when the car floor movable part 33 is in an installed state, the screw members 14a, 14b, and 14c joining the car floor movable part 33 to the car floor fixed part 12 can be removed and the car floor movable part 33 can be moved away from the wall panel 25, thereby putting the car floor movable part 33 into a movable state.

[0137] In the elevator car room 3 in the second embodiment, the car floor movable part 33 does not have to be detachable from the car floor fixed part 12.

[0138] Next, elevator car room 3 in a first modified example of embodiment 2 will be described with reference to Figs.
