When attaching or detaching the wall panel 25, if 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 horizontal 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 moves away 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 wall 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 wall 10 and becomes movable relative to the car ceiling 9 and the car wall 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 left and right to the outside of the car 1.

[0071] According to steps S11 to S13, the car floor movable section 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 for installing the wall panel 25 in the first embodiment is performed by reversing the procedure for removing the wall panel 25 in the first embodiment.

[0073] The elevator cab 3 in embodiment 1 comprises a car floor 8, a car ceiling 9, and a car wall 10, the car wall 10 having a wall panel 25, the car floor 8 having a car floor fixed part 12 and a car floor movable part 13, the car floor movable part 13 being movable relative to the car floor fixed part 12 and changing 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 separated from the wall panel 25, 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 wall panel 25 can be removed by changing the car floor movable part 13 from the installed state to the movable state and moving the wall panel 25 downward. 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 attaching the wall panel 25. Therefore, the wall panel 25 can be attached and 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 so as to be detachable from the car floor fixed part 12.

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

[0077] Next, the elevator car 3 in the second embodiment will be described with reference to FIGS.

[0089] The threshold fixing portion 34 has a threshold groove 34b. The threshold groove 34b extends in the width direction of the car entrance 3a.

[0090] The threshold movable part 35 is provided on the car floor movable part 33, as will be described later.

[0091] The car floor movable part 33 is provided so as to be movable relative to the car floor fixed part 12. The car floor movable part 33 is provided so as to be rotatable relative to the car floor fixed part 12. For example, the car floor movable part 33 is provided so as to be detachable from the car floor fixed part 12. The car floor movable part 33 changes between an installed state and a movable state.

[0092] The car floor movable section 33 has a floor panel movable section 36 and two support plates 37. The floor panel movable section 36 has a floor panel 36a. The car floor movable section 33 is provided with a threshold movable section 35.

[0093] When the car floor movable part 33 is in the installed state, the car floor movable part 33 and the threshold movable part 35 are in the following states.

[0094] The car floor movable part 33 is attached to the car floor fixed part 12.

[0095] The floor board 36a extends in the front-rear and left-right directions. A side surface 36b of the floor board 36a faces upward. The floor board 36a overlaps the floor board recess 15d. The floor board 36a closes the floor board recess 15d. For example, the side surface 15c of the floor board 15a and the side surface 36b of the floor board 36a overlap in a single plane.

[0096] The movable threshold part 35 extends in the width direction of the car entrance 3a. The movable threshold part 35 is located in front of the floor panel recess 15d. The movable threshold part 35 is located outside the car entrance 3a in the width direction of the car entrance 3a further than the front panel 15b, the floor panel protrusion 15e, and the threshold support beam 19. The movable threshold part 35 is not attached to the threshold support beam 19. The side surface 35a of the movable threshold part 35 faces upward. The side surface 35a of the movable threshold part 35 does not form the lower end of the car entrance 3a.

[0097] The movable threshold portion 35 has a threshold groove 35b. The threshold groove 35b extends in the width direction of the car entrance 3a.

[0098] The movable threshold part 35 is located outside the car entrance 3a in the width direction of the car entrance 3a relative to the fixed threshold part 34. The fixed threshold part 34 and the movable threshold part 35 are connected in the width direction of the car entrance 3a. The side surface 34a of the fixed threshold part 34 and the side surface 35a of the movable threshold part 35 overlap on a single plane.

[0099] The threshold grooves 34b and 35b are connected in the width direction of the car entrance 3a. The side surface 34c that forms the width of the threshold groove 34b and the side surface 35c that forms the width of the threshold groove 35b overlap in a single plane. The side surface 34d that forms the width of the threshold groove 34b and the side surface 35d that forms the width of the threshold groove 35b overlap in a single plane. The threshold grooves 34b and 35b guide the movement of the car door 11. When the car door 11 closes the car entrance 3a, the door leg 11a is inserted into the threshold groove 34b. When the car door 11 opens the car entrance 3a, the door leg 11a moves into the threshold groove 35b.

[0100] For example, the threshold movable part 35 is connected to the floor board 36a. For example, the threshold movable part 35 and the floor board 36a are formed by bending a single plate-shaped member.

[0101] The support plate 37 extends in the front-to-rear and up-down directions. The support plate 37 is located below the left edge and the right edge of the floor plate 36a. The support plate 37 is attached to the floor plate 36a. For example, the support plate 37 is located below the movable threshold part 35. For example, the support plate 37 is attached to the movable threshold part 35.

[0102] The screw members 14a, 14b, and 14c detachably join the car floor fixed part 12 and the car floor movable part 33. The screw members 14a and 14b detachably join the connecting plate 18 and one of the support plates 22. The screw member 14d detachably joins the connecting beam 16 and the other support plate 22.

[0103] The shanks of screw members 14b and 14c extend horizontally. For example, the shanks of screw members 14b and 14c extend in the width direction of the wall panel 25. The center line of the shank of screw member 14b and the center line of the shank of screw member 14c overlap on a single straight line. The center line of the shank of screw member 14b and the center line of the shank of screw member 14c are located below the car floor fixed part 12. For example, the center line of the shank of screw member 14b and the center line of the shank of screw member 14c are located further inward of the car floor fixed part 12 than the wall panel 25 in the thickness direction of the wall panel 25.

[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 a screw member 10g.

[0105] The size of the projection surface of the wall panel 25 and the car operating panel 31 projected perpendicularly onto a horizontal plane is such that it fits within the projection surface of the floor panel recess 15d and the movable threshold part 35 projected perpendicularly onto a 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 around the center line of the shank of the screw member 14b and the center line of the shank 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, and the car floor movable part 33 does not cover the floor panel recess 15d.

[0109] The movable threshold part 35 rotates integrally with the movable car floor part 33, and is thereby in a state of being moved downward. The movable threshold part 35 is positioned lower than the movable threshold part 35 when the movable car floor part 33 is in the installed state. The movable threshold part 35 is not positioned in front of the floor panel recess 15d. The movable threshold part 35 is farther from the wall panel 25 than the movable threshold part 35 when the movable car floor part 33 is in the installed state.

[0110] The screw member 14a does not join the car floor fixed part 12 and the car floor movable part 33. The screw member 14a does not join the connecting plate 18 and one of the support plates 37. The screw members 14b and 14c rotatably join the car floor fixed part 12 and the car floor movable part 33. The screw member 14b rotatably joins the connecting plate 18 and one of the support plates 37. The screw member 14c rotatably joins the connecting beam 16 and the other support plate 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 member 10g. The car floor movable part 33 is separated from the wall panel 25.

[0112] The elevator car 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 or detached by placing the car floor movable part 33 in a movable state and moving the wall panel 25 in the up and down direction. When attaching or 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 or detaching the wall panel 25, if the wall panel 25 is positioned below the support body 4a of the car door opening and closing device 4, the wall panel 25 can be moved in the front-to-rear direction. When attaching or detaching the wall panel 25, if 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-to-right direction. Therefore, the wall panel 25 can be attached or detached with the car operating 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 put 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 separates from the wall panel 25, and the car floor movable part 33 can be put into a moving state. When the car floor movable part 33 is put into a moving state, the threshold movable part 35 rotates integrally with the car floor movable part 33 and moves downward.

[0118] In step S22 (wall panel separation step), the wall panel 25 is separated from the car ceiling 9 and the car wall 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 wall 10 and becomes movable relative to the car ceiling 9 and the car wall 10.

[0119] In step S23 (wall panel removal step), the wall panel 25 is removed by moving it downward and forward. When moving the wall panel 25 downward to remove it from the car chamber 3, moving the wall panel 25 forward can prevent the car operating panel 31 from hitting the car floor fixed portion 12. 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 left and right to the outside of the passenger car 1. When the wall panel 25 is positioned below the support member 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 moving the wall panel 25 left and right to the outside of the passenger car 1, moving the wall panel 25 forward can prevent the car operating 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, thereby making it possible to remove the wall panel 25 and the operation panel 31.

[0121] The method for installing the wall panel 25 in the second embodiment is performed by reversing the procedure for 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 on 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 movable threshold part 35 is arranged to be movable relative to the fixed threshold part 34, and when the movable car floor part 33 is in an installed state, the movable threshold part 35 is located outside one side of the car entrance / exit 3a in the width direction at the fixed threshold part 34, and the fixed threshold part 34 and the movable threshold part 35 are connected in the width direction of the car entrance / exit 3a, and when the movable car floor part 33 is in a moving state, the movable threshold part 35 is not located outside one side of the car entrance / exit 3a in the width direction at the fixed threshold 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 obstructed 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 obstructed 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 provided 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 to the inside of the car room 3, when the wall panel 25 is moved in the vertical direction to detach the wall panel 25, the operation panel 31 can be separated from the car floor fixing part 12 by moving the wall panel 25 forward.

[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 relative 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 according to 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 using hinges instead of the screw members 14b and 14c.

[0133] In the elevator car 3 in the second embodiment, as shown in FIG. 19, the movable threshold part 35 and the floor board 36a may be formed of separate members and detachably joined together 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 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 shank of the screw member 14b and the center line of the shank 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 movable threshold 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 that join 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 making it possible to move the car floor movable part 33.

[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, an elevator car 3 according to a first modified example of the second embodiment will be described with reference to FIGS.
