The landing door 22 includes a door panel 23, a door hanger 24, and a door roller 25.

The door panel 23 opens and closes the doorway formed in the landing 20. In the following, the entrance / exit formed in the landing 20 will also be referred to as the landing entrance / exit. The door hanger 24 is provided on the upper part of the door panel 23 so as to extend upward from the door panel 23. The door roller 25 is rotatably provided on the door hanger 24. The door rail 26 is arranged horizontally above the entrance / exit of the landing. By placing the door roller 25 on the door rail 26, the landing door 22 is suspended from the door rail 26. The door roller 25 rolls on the upper surface of the door rail 26. As a result, the movement of the upper part of the landing door 22 is guided. The movement of the lower part of the landing door 22 is guided by the threshold 27.

In this embodiment, an example is shown in which the door assembly 21 includes a double door type landing door 22. That is, the door assembly 21 includes a pair of landing doors 22. When it is necessary to specify the landing door 22 individually in the following, as shown in FIG. 3, a is added after the code for one landing door. Similarly, for the other landing door, b is added after the code. That is, the landing door 22a includes a door panel 23a, a door hanger 24a, and a door roller 25a. The landing door 22b includes a door panel 23b, a door hanger 24b, and a door roller 25b.

The interlocking device 28 is provided on the door hanger 24. The interlocking device 28 is a device for moving the landing door 22 in accordance with the movement of the car door 11. For example, the interlocking device 28 provided in the landing 20 on the 5th floor has a function of moving the landing door 22 in accordance with the movement of the car door 11 when the car 1 is stopped at the landing 20 on the 5th floor. In the following, when the equipment provided in the landing 20 is described, the landing where the equipment is provided is also referred to as the landing. The interlocking device 28 locks the landing door 22 if the car 1 is not stopped at the landing 20. For example, the interlocking device 28 locks the landing door 22 if the car 1 is stopped at the landing 20 on another floor. FIG. 4 is a diagram showing the upper part of the door assembly 21. The interlocking device 28 includes a lock member 29, a shaft 30, a roller 31, an arm 32, and a roller 33.

The shaft 30 is provided on the door hanger 24a. The lock member 29 is provided on the door hanger 24a via the shaft 30. That is, the lock member 29 rotates about the shaft 30. The locking member 29 can be displaced between the locking position and the unlocking position. The locking position is a position for locking the landing door 22. FIG. 4 shows an example in which the lock member 29 is arranged at the locked position. The tip of the lock member 29 arranged at the lock position faces the receiving member 34. When the landing door 22 moves from the fully closed position to the opening direction with the lock member 29 arranged at the locked position, the tip portion of the lock member 29 hangs on the receiving member 34. As a result, the opening operation of the landing door 22 is prevented.

The unlocking position is a position for allowing the landing door 22 to be opened and closed. If the lock member 29 is arranged at the unlocked position, the lock member 29 does not come into contact with the receiving member 34 even if the landing door 22 moves in the opening direction. The lock member 29 is constantly subjected to a force so as to be arranged at the locked position by a member (not shown) such as a spring. Therefore, if no external force acts on the interlocking device 28, the locking member 29 is arranged at the locking position. The landing door 22 is unlocked by arranging the lock member 29 at the unlocked position.

The roller 31 is provided on the door hanger 24a via the shaft 30. That is, the roller 31 rotates about the shaft 30. The arm 32 is integrated with the lock member 29 and rotates about the shaft 30. The arm 32 extends obliquely upward from the shaft 30. A roller 33 is rotatably provided at the upper end of the arm 32. For example, the diameter of the roller 33 is the same as the diameter of the roller 31. The rotation center of the roller 33 is arranged at a position closer to the door hanger 24b than the rotation center of the roller 31.

In FIG. 4, the position of the vane 14 immediately after the car 1 stops at the landing 20 is shown by a dashed line. When the car 1 stops at the landing 20, the rollers 31 and 33 are arranged between the two plates that make up the vane 14. When the car door 11 moves in the opening direction in this state, the vane 14 comes into contact with the roller 33. If the car door 11 moves in the opening direction even after the vane 14 comes into contact with the roller 33, the roller 33 is displaced by being pushed by the vane 14. As a result, the arm 32 and the lock member 29 rotate around the shaft 30, and the lock member 29 is arranged at the unlocked position. That is, the landing door 22 is unlocked. After that, when the roller 33 is displaced until the vane 14 comes into contact with the roller 31, the roller 31 is pushed by the vane 14 to start the movement of the landing door 22. That is, the landing door 22 moves in the opening direction together with the car door 11.

FIG. 5 is a diagram showing a BB cross section of FIG. FIG. 6 is a diagram showing the lower part of the door assembly 21. The intrusion prevention device 35 is provided on the door panel 23b. FIG. 6 shows an example in which two intrusion prevention devices 35 are provided on the door panel 23b. The entry prevention device 35 is a device for preventing passengers from entering the hoistway 3. For example, the entry prevention device 35 provided in the landing 20 on the 5th floor is arranged so as to cross the landing entrance / exit when the landing door 22 is opened when the car 1 is not stopped on the 5th floor. Even if the landing door 22 is opened when the car 1 is stopped at the landing 20, the entry prevention device 35 is not arranged so as to cross the landing entrance / exit.

The intrusion prevention device 35 includes, for example, a string-shaped member 36 and a winder 37. The winder 37 is provided on the door panel 23b. The string-shaped member 36 is wound by the winder 37.

The connecting member 41 can be arranged at the first position and the second position. The first position is a position for connecting to the intrusion prevention device 35. As shown in FIG. 6, the connecting member 41 includes a hook 44. When the hook 44 is hooked on the pin 39, the connecting member 41 is connected to the intrusion prevention device 35. If the connecting member 41 is arranged at the first position, the hook 44 projects from the end surface of the door panel 23a toward the door panel 23b. In FIG. 6, the connecting member 41 arranged at the first position is shown by a solid line.

The second position is a position that deviates from the entry prevention device 35. That is, if the connecting member 41 is arranged at the second position, the hook 44 does not hang on the pin 39. In FIG. 6, the connecting member 41 arranged at the second position is shown by a broken line. If the connecting member 41 is arranged at the second position, the connecting member 41 does not protrude from the end surface of the door panel 23a. When the landing door 22 moves with the car door 11, the connecting member 41 is arranged at the second position.

When the car door 11 is opened while the car 1 is stopped at the landing 20, the displacement member 42 is pushed by the member provided on the car door 11 and is displaced. The transmission mechanism 43 is a mechanism for transmitting the displacement of the displacement member 42 to the connecting member 41. When the displacement member 42 is pushed by the member and displaced, the transmission mechanism 43 displaces the connecting member 41 arranged at the first position to the second position.

In the example shown in FIGS. 3 to 6, the displacement member 42 is a roller arranged directly below the roller 33. Further, in the examples shown in FIGS. 3 to 6, the member for pushing and displaces the displacement member 42 is the vane 14. In the example shown in FIGS. 3 to 6, the transmission mechanism 43 includes links 45 to 48 and shafts 49 to 50.

The shaft 49 is provided on the door panel 23a. The link 45 is provided on the door panel 23a via the shaft 49. That is, the link 45 rotates about the shaft 49. One end of the link 45 extends obliquely upward from the portion supported by the shaft 49. A displacement member 42 is rotatably provided at one end of the link 45. The other end of the link 45 extends laterally from the portion supported by the shaft 49. The upper end of the link 46 is rotatably connected to the other end of the link 45.

The shaft 50 is provided on the door panel 23a. The link 47 is provided on the door panel 23a via the shaft 50. That is, the link 47 rotates about the shaft 50. One end of the link 47 extends obliquely upward from the portion supported by the shaft 50. An upper end of the connecting member 41 is rotatably provided at one end of the link 47. That is, the connecting member 41 is supported by the link 47. The other end of the link 47 extends laterally from the portion supported by the shaft 50. The lower end of the link 46 is rotatably connected to the other end of the link 47.

Further, the link 48 is arranged in parallel with the portion of the link 47 that extends diagonally upward from the portion supported by the shaft 50. A lower end of the connecting member 41 is rotatably provided at one end of the link 48. That is, the connecting member 41 is supported by the link 48. The other end of the link 48 is rotatably provided on the door panel 23a.

If no external force is acting on the displacement member 42, the connecting member 41 is arranged at the first position. For example, if the car 1 is not stopped at the landing 20, the connecting member 41 is arranged at the first position. When the landing door 22 is opened while the car 1 is not stopped at the landing 20, the hook 44 is hooked on the pin 39. If the landing door 22 moves in the opening direction even after the hook 44 is hooked on the pin 39, the pin 39 is pulled by the hook 44 and the string-shaped member 36 is pulled out from the winder 37. As a result, the string-shaped member 36 is arranged between the door panel 23a and the door panel 23b so as to cross the landing entrance / exit. FIG. 7 is a diagram showing an example in which the entry prevention device 35 is arranged so as to cross the landing entrance / exit.

On the other hand, when the car 1 is stopped at the landing 20, the rollers 31 and the rollers 33 of the landing 20 are arranged between the two plates constituting the vane 14. Further, as shown in FIG. 4, the displacement member 42 is also arranged between the two plates constituting the vane 14. When the car door 11 moves in the opening direction in this state, the vane 14 comes into contact with the displacement member 42. If the car door 11 moves in the opening direction even after the vane 14 comes into contact with the displacement member 42, the displacement member 42 is displaced by being pushed by the vane 14. As a result, the link 45 rotates about the axis 49 in the C direction. As the link 45 rotates in the C direction, the link 46 moves in the D direction as shown in FIGS. 4 and 6.

When the link 46 is displaced in the D direction, the link 47 rotates in the E direction about the axis 50. As a result, the connecting member 41 moves diagonally upward, and the connecting member 41 arranged at the first position is displaced to the second position. The displacement of the connecting member 41 to the second position is completed when the vane 14 comes into contact with the roller 31. As described above, the connecting member 41 arranged at the second position does not protrude from the end surface of the door panel 23a. Further, when the connecting member 41 is arranged at the second position, the hook 44 does not hang on the pin 39. Therefore, even if the landing door 22 starts the opening operation by pushing the roller 31 by the vane 14, the string-shaped member 36 is not pulled out from the winder 37.

In the example shown in the present embodiment, it is possible to prevent the maintenance staff from inadvertently entering the landing entrance / exit at the landing 20 where the car 1 is not stopped. Further, in the example shown in the present embodiment, the entry prevention device 35 and the transmission mechanism 43 do not obstruct the passage when the passenger gets on and off the car 1.

8 and 9 are views showing another example of the door device according to the first embodiment. FIG. 8 is a diagram corresponding to FIG. FIG. 9 is a diagram corresponding to FIG. In the examples shown in FIGS. 8 and 9, the entry prevention device 35 is different from the above-described example.

In the example shown in FIGS. 8 and 9, the entry prevention device 35 includes a rod-shaped member 51, a holding member 52, and a spring member 53. The holding member 52 is provided on the door panel 23b. The holding member 52 holds the rod-shaped member 51 so that the rod-shaped member 51 can be displaced in the moving direction of the landing door 22. The spring member 53 constantly applies a force to the rod-shaped member 51 in the direction away from the door panel 23a. The rod-shaped member 51 includes a pin 39 at its tip. The tip end portion of the rod-shaped member 51 is arranged so as not to protrude from the end surface of the door panel 23b toward the door panel 23a unless an external force acts.

Even in the examples shown in FIGS. 8 and 9, if no external force is applied to the displacement member 42, the connecting member 41 is arranged at the first position. When the landing door 22 is opened while the car 1 is not stopped at the landing 20, the hook 44 is hooked on the pin 39. If the landing door 22 moves in the opening direction even after the hook 44 is hooked on the pin 39, the pin 39 is pulled by the hook 44 and the rod-shaped member 51 is pulled out from the holding member 52. As a result, the rod-shaped member 51 is arranged between the door panel 23a and the door panel 23b so as to cross the landing entrance / exit. FIG. 10 is a diagram showing an example in which the entry prevention device 35 is arranged so as to cross the landing entrance / exit.

When the car 1 is stopped at the landing 20, the displacement member 42 of the landing 20 is arranged between the two plates constituting the vane 14. When the car door 11 moves in the opening direction in this state, the displacement member 42 is pushed by the vane 14 to be displaced, and the link 46 moves in the D direction. When the link 46 is displaced in the D direction, the link 47 rotates in the E direction about the axis 50. As a result, the connecting member 41 moves diagonally upward, and the connecting member 41 arranged at the first position is displaced to the second position. The connecting member 41 arranged at the second position does not protrude from the end surface of the door panel 23a. Further, when the connecting member 41 is arranged at the second position, the hook 44 does not hang on the pin 39. Therefore, even if the landing door 22 starts the opening operation by pushing the roller 31 by the vane 14, the rod-shaped member 51 is not pulled out from the holding member 52.

Even in the examples shown in FIGS. 8 to 10, it is possible to prevent the maintenance staff from inadvertently entering the entrance / exit of the landing at the landing 20 where the car 1 is not stopped. Further, when the passenger gets on and off the car 1, the entry prevention device 35 and the transmission mechanism 43 do not obstruct the passage.

11 and 12 are views showing another example of the door device according to the first embodiment. FIG. 11 is a diagram corresponding to FIG. FIG. 12 is a diagram corresponding to FIG.

Further, in the examples shown in FIGS. 11 and 12, the member for pushing and displaces the displacement member 42 is the cam 15. The cam 15 is provided on the car door 11. The cam 15 is located below the vane 14. In the examples shown in FIGS. 11 and 12, the transmission mechanism 43 includes links 47-48 and a shaft 50.

The shaft 50 is provided on the door panel 23a. The link 47 is provided on the door panel 23a via the shaft 50. The link 47 rotates about the shaft 50. In the examples shown in FIGS. 11 and 12, the link 47 is an L-shaped member. One end of the link 47 extends obliquely upward from the portion supported by the shaft 50. An upper end of the connecting member 41 is rotatably provided at one end of the link 47. The connecting member 41 is supported by the link 47. The other end of the link 47 extends obliquely upward from the portion supported by the shaft 50. A displacement member 42 is rotatably provided at the other end of the link 47.

Even in the examples shown in FIGS. 11 and 12, if no external force is applied to the displacement member 42, the connecting member 41 is arranged at the first position. When the landing door 22 is opened while the car 1 is not stopped at the landing 20, the hook 44 is hooked on the pin 39. If the landing door 22 moves in the opening direction even after the hook 44 is hooked on the pin 39, the pin 39 is pulled by the hook 44 and the string-shaped member 36 is pulled out from the winder 37. As a result, the string-shaped member 36 is arranged between the door panel 23a and the door panel 23b so as to cross the landing entrance / exit.

On the other hand, when the car 1 is stopped at the landing 20, the displacement member 42 of the landing 20 is arranged so as to face the cam 15. In FIG. 12, the position of the cam 15 immediately after the car 1 stops at the landing 20 is shown by a dashed line. When the car door 11 moves in the opening direction in this state, the cam 15 comes into contact with the displacement member 42. If the car door 11 moves in the opening direction even after the cam 15 comes into contact with the displacement member 42, the displacement member 42 is displaced by being pushed by the cam 15. As a result, the link 47 rotates about the shaft 50 in the E direction.

When the link 47 rotates in the E direction, the connecting member 41 moves diagonally upward, and the connecting member 41 arranged at the first position is displaced to the second position. The displacement of the connecting member 41 to the second position is completed when the vane 14 comes into contact with the roller 31. As described above, the connecting member 41 arranged at the second position does not protrude from the end surface of the door panel 23a. Further, when the connecting member 41 is arranged at the second position, the hook 44 does not hang on the pin 39. Therefore, even if the landing door 22 starts the opening operation by pushing the roller 31 by the vane 14, the string-shaped member 36 is not pulled out from the winder 37.

Even in the examples shown in FIGS. 11 and 12, it is possible to prevent the maintenance staff from inadvertently entering the entrance / exit of the landing at the landing 20 where the car 1 is not stopped. Further, when the passenger gets on and off the car 1, the entry prevention device 35 and the transmission mechanism 43 do not obstruct the passage.
