  • the auxiliary unlocking member 63 is provided on the second right-side landing door 9a at each landing floor where a second interlock device 21b that is not a car door unlocking interlock device is provided.
  • the auxiliary unlocking member 63 is also provided at a position on the second right-side landing door 9a that corresponds to the second unlocking mechanism 45.
  • a maintenance unlocking member 65 and a maintenance guide body 66 may be provided above the first landing entrance 10a on the top floor in the elevator 1.
  • the maintenance unlocking member 65 is guided by the maintenance guide body 66 and can move in a direction parallel to the opening and closing direction of the right car door 7a and the left car door 7b.
  • the maintenance unlocking member 65 is a roller similar to the auxiliary unlocking member 63.
  • first unlocking mechanism 41 may be extended upward so that the vertical dimension of the first unlocking mechanism 41 is greater than the vertical dimension of the second unlocking mechanism 45.
  • the worker moves the maintenance unlocking member 65 to a position directly above the first unlocking mechanism 41 before moving the car 6 above the door-opening area. After this, the car 6 is moved above the top floor, so that the maintenance unlocking member 65 faces the first unlocking mechanism 41.
  • car 6 becomes unable to move during maintenance work on the car, the worker moves into car 6 from the ceiling rescue exit and manually moves right car door 7a and left car door 7b in the opening direction.
  • the first unlocking mechanism 41 hits the maintenance unlocking member 65, allowing the right car door 7a and the left car door 7b to open.
  • the car door locking mechanism 51 allows the right car door 7a and the left car door 7b to open even when the first unlocking mechanism 41 hits the maintenance unlocking member 65.
  • the worker After moving the right car door 7a and the left car door 7b to a certain extent in the opening direction, the worker uses a door fixing tool (not shown) to prevent the right car door 7a and the left car door 7b from moving in the closing direction. After this, the worker manually unlocks the first interlock device 21a and manually moves the first right landing door 8a and the first left landing door 8b in the opening direction, allowing the worker to escape to the landing.
  • auxiliary unlocking member 63 and the maintenance unlocking member 65 are not limited to rollers.
  • the configuration of the car door locking mechanism 51 is not limited to the above configuration.
  • Embodiment 3 Next, an elevator apparatus according to embodiment 3 will be described.
  • the height dimensions of the landing entrances at all landing floors are the same or the difference in height dimensions of the landing entrances is small, so the installation height of the first unlocking mechanism 41 relative to the car entrance 6a is the same as the installation height of the second unlocking mechanism 45 relative to the car entrance 6a.
  • FIG. 13 is a front view of the landing door device for the lowest floor in an elevator system according to embodiment 3, as seen from the hoistway 1 side.
  • the second interlock device 21b installed on the lowest floor is equipped with a pit unlocking mechanism 26.
  • the pit unlocking mechanism 26 has, for example, a flexible operating member. For example, a wire or rope is used as the operating member.
  • the operating member is connected to the latch 23.
  • a pit ladder (not shown) is installed in the pit of the elevator shaft 1.
  • the pit ladder is used by workers to move between the lowest floor landing and the pit.
  • the second interlock device 21b is manually unlocked by the worker operating the operating member from the pit or the pit ladder.
  • the pit unlocking mechanism 26 is installed on the landing door on the side where the latch 23 is installed. Also, the pit ladder is installed below the landing door on which the pit unlocking mechanism 26 is installed.
  • the layout of the elevator system may mean that it is not possible to install a pit ladder below the landing door on the side where the latches 23 are installed. In that case, the pit ladder and the pit unlocking mechanism 26 will be separated to the left and right, making it difficult to operate the pit unlocking mechanism 26 from the pit ladder.
  • the car 6 is provided with a first unlocking mechanism 41 and a second unlocking mechanism 45, and the second interlock device 21b is disposed on the opposite side to each of the first interlock devices 21a at the other landing floors.
  • the height dimensions of different landing entrances and exits may be different.
  • the number of landing entrances with large height dimensions is not particularly limited and may be two or more.
  • the number of landing entrances with small height dimensions is not particularly limited.
  • the height dimension of the landing entrance on the lowest floor may be smaller than the height dimensions of landing entrances on floors other than the lowest floor.
  • the number of height dimension patterns of the landing entrance may be three or more.
  • the structure and size of the first interlock device do not have to be the same as the structure and size of the second interlock device.
  • the car door device and the landing door device may be a single-leaf door device.
  • the number of door panels in each of the car door device and the landing door device may be one or three or more.
  • the layout of the elevator system is not limited to the layout shown in FIG. 1.
  • the hoist 3 may be installed at a location other than the top of the hoistway 1.
  • the elevator system may also be an elevator system with a machine room, a double-deck elevator, a one-shaft multi-car elevator, etc.
  • the one-shaft multi-car system is a system in which an upper car and a lower car located directly below the upper car each independently ascend and descend in a common elevator shaft.
