According to the first embodiment described above, the rail connecting mechanism 15 rotatably and slidably connects the member on the landing side and the member on the guide rail side. Therefore, it can be applied to a seismic isolated building with a simple structure.

Specifically, when the landing and the guide rail 5 are relatively displaced in the depth direction of the landing entrance / exit 7, the door device 12 or the like on the landing side tilts in the depth direction of the landing entrance / exit 7. Therefore, it is possible to avoid interference between the car 6 and the equipment at the landing. As a result, in the elevator in which the car 6 and the door device 12 are engaged to open and close the door 11, the engaged state can be maintained.

Further, the rail connecting mechanism 15 connects the door connecting beam 20 and the rail connecting beam 19 in a rotatable and slidable manner.

The first opening 34 follows the passage frame 29 and the landing passage 33 expands and contracts in the depth direction of the doorway while the first opening 34 follows the guide rail 5 and inclines in the depth direction of the landing entrance / exit 7. Therefore, when the three-sided frame 21 is tilted in the depth direction of the landing entrance / exit 7, it is possible to suppress a change in the gap in the depth direction of the landing entrance / exit 7 between the first opening 34 of the landing passage 33 and the three-sided frame 21. As a result, it is possible to prevent the landing passage 33 and the three-sided frame 21 from interfering with each other, or to prevent people, objects, or the like from being caught between the landing passage 33 and the three-sided frame 21.

Further, the sill device 13 includes a sill fixing portion 24, a sill movable portion 25, and a sill connecting mechanism 26. Therefore, in an elevator installed in a building equipped with a seismic isolation device 3, when the landing and the guide rail are relatively displaced due to an earthquake, the car 6, the door device 12, the sill device 13, and the door 11 Changes in the relative position of the doorway in the width direction can be suppressed. As a result, it is possible to prevent people and objects from being drawn into the gap between the car 6 door and the landing door 11. Further, in the elevator in which the car 6 and the door device 12 of the landing are engaged to open and close the door 11, the engaged state can be maintained.

Further, the vertical frame 22 is connected to the sill movable portion 25. Therefore, when the door device 12 and the door 11 of the landing move in the width direction of the landing entrance / exit 7, the relative displacement of the door 11 of the landing and the doorway of the three-sided frame 21 in the width direction does not occur. As a result, it is possible to prevent people and objects from being drawn between the landing door 11 and the three-sided frame 21.

In addition, the landing passage 33 connects the first opening 34 and the second opening 35 in a stretchable manner in the depth direction of the entrance / exit of the landing. Therefore, when the three-sided frame 21 is tilted in the depth direction of the landing entrance / exit 7, it is possible to suppress a change in the gap in the depth direction of the landing entrance / exit 7 between the first opening 34 of the landing passage 33 and the three-sided frame 21. As a result, it is possible to prevent the landing passage 33 and the three-sided frame 21 from interfering with each other and the person or object from being caught between the landing passage 33 and the three-sided frame 21.

Further, the threshold connecting mechanism 26 includes a roller support portion 40 and a roller portion 41. Therefore, when the sill movable portion 25 moves in the width direction of the landing entrance / exit 7, the sill movable portion 25 can be smoothly guided while suppressing vibration and noise.

Further, the sill movable part 25 is provided with a saucer 47. Therefore, it is possible to prevent dust, dirt, etc. from entering the inside of the sill device 13 and causing the sill connecting mechanism 26 to break down. In addition, regular maintenance can prevent the threshold connection mechanism 26 from breaking down for a long period of time.

Further, the threshold device 13 includes a jack mechanism 48. Therefore, maintenance and replacement of the threshold connecting mechanism 26 can be easily performed.

As described above, the elevator landing system according to the present invention can be used for the elevator system.
