[0030] The plurality of landing floors include at least one first landing floor 51 and at least one second landing floor 52 different from the first landing floor 51. In this example, the lowermost floor is the first landing floor 51, and each landing floor other than the lowermost floor is the second landing floor 52.

[0031] A first landing entrance 51a is provided between the landing of the first landing floor 51 and the hoistway 1. A second landing entrance 52a is provided between the landing of each second landing floor 52 and the hoistway 1.

[0032] The height dimension h1 of the first landing entrance 51a and the height dimension h2 of each second landing entrance 52a are different from each other. In this example, the height dimension h1 of the first landing entrance 51a is greater than the height dimension h2 of each second landing entrance 52a. The height dimension of the landing entrance is the vertical dimension from the landing floor to the upper end of the landing entrance.

[0033] A first landing door device is provided on the first landing floor 51.

The first left landing door 8b is the landing door located on the left side when observing the first landing entrance 51a from the landing.

[0034] In the first landing door device, the first right landing door 8a and the first left landing door 8b move in opposite directions in a mechanically interlocked manner, thereby opening and closing the first landing entrance 51a. In addition, in the first landing door device, the first right landing door 8a and the first left landing door 8b are opened and closed in a linked manner with the right car door 7a and the left car door 7b when the car 6 stops.

[0035] A second landing door device is provided on each second landing floor 52. Each second landing door device has a second right landing door 9a and a second left landing door 9b as a pair of second landing doors. The second right landing door 9a is the landing door located on the right side when observing the second landing entrance 52a from the landing. The second left landing door 9b is the landing door located on the left side when observing the second landing entrance 52a from the landing.

[0036] In each second landing door device, the second right landing door 9a and the second left landing door 9b are mechanically linked to each other and move in opposite directions, thereby opening and closing the corresponding second landing entrance 52a. In addition, in each second landing door device, the second right landing door 9a and the second left landing door 9b are opened and closed in linkage with the right car door 7a and the left car door 7b when the car 6 stops.

[0037] Figure 2 Viewed from the shaft 1 side Figure 1 The front view of the first floor door device in the elevator device. Figure 2 In the figure, since the first landing door device is viewed from the side opposite to the landing, the first right landing door 8a is located on the left side, and the first left landing door 8b is located on the right side.

[0038] A landing door frame 11 is fixed to the first landing doorway 51a. A landing door rail 12 is provided on the landing door frame 11. The landing door rail 12 is parallel to and horizontal to the width direction of the first landing doorway 51a. The width direction of the first landing doorway 51a is parallel to the opening and closing direction of the first right landing door 8a and the first left landing door 8b. Figure 2 left and right direction.

[0039] The first right landing door 8a and the first left landing door 8b respectively include a landing door panel 13 and a landing door hanger 14. Each landing door hanger 14 is fixed to the upper portion of the corresponding landing door panel 13.

[0040] The first right landing door 8a and the first left landing door 8b are suspended from the landing door track 12 and open and close along the landing door track 12. A first landing door interlocking mechanism (not shown) is provided on the landing door frame 11. The first landing door interlocking mechanism mechanically interlocks the first right landing door 8a and the first left landing door 8b.

[0041] The first interlocking device 21 is provided between the first left landing door 8b and the landing door frame 11. That is, the first interlocking device 21 is provided above the first landing doorway 51a. The first interlocking device 21 prevents the first right landing door 8a and the first left landing door 8b from opening.

[0042] The first interlocking device 21 has a first hook 22 , a first latch 23 , a first fixed-side interlocking roller 24 , and a first movable-side interlocking roller 25 as a first unlocking member.

[0043] The first hook 22 is provided above the first landing entrance 51a and fixed to the landing door frame 11. The first latch 23 is rotatably provided on the landing door hanger 14 of the first left landing door 8b. When the first right landing door 8a and the first left landing door 8b are in the fully closed position, the first latch 23 is hooked to the first hook 22 to prevent the opening of the first right landing door 8a and the first left landing door 8b.

[0044] The first fixed-side interlocking roller 24 is arranged coaxially with the rotation axis of the first latch 23. The first movable-side interlocking roller 25 is rotatably provided on the first latch 23. The first movable-side interlocking roller 25 can move along an arc centered on the rotation axis of the first latch 23 by the rotation of the first latch 23.

[0045] Figure 3 as viewed from the hoistway 1 side Figure 1 is a front view of the second landing door device in the elevator device. In Figure 3 this, since the second landing door device is viewed from the side opposite to the landing, the second right landing door 9a is located on the left side and the second left landing door 9b is located on the right side.

[0046] In the second landing door device, the second right landing door 9a and the second left landing door 9b respectively have a landing door panel 13 and a landing door hanger 14. However, the vertical dimension of each landing door panel 13 in the second landing door device is smaller than the vertical dimension of each landing door panel 13 in the first landing door device.

[0047] An unillustrated second landing door linkage mechanism is provided in the landing door frame 11 of the second landing door device. The second landing door linkage mechanism mechanically interlocks the second right landing door 9a and the second left landing door 9b with each other.

[0048] A second interlock device 31 is provided between the second left landing door 9b and the landing door frame 11. That is, the second interlock device 31 is provided above the second landing entrance 52a. The second interlock device 31 prevents the opening of the second right landing door 9a and the second left landing door 9b.

[0049] The second interlock device 31 includes a second hook 32, a second latch 33, a guide body 34, a movable body 35, a transmission mechanism 36, and a stopper 37.

[0050] The second hook 32 is provided above the second landing entrance 52a and fixed to the landing door frame 11. The second latch 33 is rotatably provided on the landing door hanger 14 of the second left landing door 9b. When the second right landing door 9a and the second left landing door 9b are in the fully closed position, the second latch 33 is hooked to the second hook 32 to prevent the opening of the second right landing door 9a and the second left landing door 9b.

[0051] The guide body 34 is disposed above the second landing entrance 52a. Further, the guide body 34 is fixed to the upper portion of the landing door frame 11.

[0052] The movable body 35 is disposed above the second latch 33 leaving the second latch 33 and is movable in a direction parallel to the opening and closing operation direction of the second left landing door 9b. Further, the movable body 35 moves together with the second left landing door 9b along the guide body 34 during the opening and closing operation of the second left landing door 9b. The guide body 34 guides the movement of the movable body 35.

[0053] The transmission mechanism 36 is connected between the movable body 35 and the second latch 33. The stopper 37 is disposed on the guide body 34. When the second left landing door 9b is in the fully closed position, the movable body 35 abuts against the stopper 37. Thereby, the moving range of the movable body 35 in the closing direction of the second left landing door 9b is restricted.

[0054] Figure 4 is an enlarged view Figure 3 of the main part. The movable body 35 has a support member 41, a pair of main rollers 42, a pair of auxiliary rollers 43, a second fixed-side interlocking roller 44, and a second movable-side interlocking roller 45 as a second unlocking member.

[0055] The support member 41 is disposed above the second latch 33 and is movable along the guide body 34 in a direction parallel to the opening and closing operation direction of the second left landing door 9b.

[0056] A pair of main rollers 42 and a pair of auxiliary rollers 43 are disposed on the support member 41. The pair of main rollers 42 and the pair of auxiliary rollers 43 are arranged on the support member 41 on the side opposite to the second fixed-side interlocking roller 44 and the second movable-side interlocking roller 45.

[0057] When moving the support member 41, the pair of main rollers 42 roll and move on the guide body 34. Each auxiliary roller 43 is disposed directly below the corresponding main roller 42. Further, each auxiliary roller 43 prevents the corresponding main roller 42 from coming off the guide body 34.

[0058] The second fixed-side interlocking roller 44 is rotatably disposed above the second latch 33 on the support member 41.

[0059] The second movable-side interlocking roller 45 is supported on the support member 41 directly above the second fixed-side interlocking roller 44. Further, the second movable-side interlocking roller 45 is movable along an arc centered on the rotation axis of the second fixed-side interlocking roller 44.

[0060] The transmission mechanism 36 is provided between the second fixed-side interlocking roller 44, the second movable-side interlocking roller 45 and the second latch 33, and transmits the movement of the second movable-side interlocking roller 45 relative to the support member 41 to the second latch 33.

[0061] In addition, the transmission mechanism 36 includes a first link 46 and a second link 47. The first link 46 and the second link 47 are arranged parallel and vertically to each other, forming a parallel link mechanism.

[0062] The first link 46 is connected between the support member 41 and the second latch 33. Specifically, the first link 46 is connected between the rotation axis of the second latch 33 and the rotation axis of the second fixed-side interlocking roller 44.

[0063] The second link 47 is connected between the second movable-side interlocking roller 45 and the second latch 33. Specifically, the second link 47 is rotatably connected to the second latch 33 obliquely above the rotation axis of the second latch 33, and is rotatably connected to the rotation axis of the second movable-side interlocking roller 45.

[0064] By moving the second movable-side interlocking roller 45 from Figure 4 its state about the rotation axis of the second fixed-side interlocking roller 44 in the Figure 4 clockwise direction, the second latch 33 also rotates in the Figure 4 clockwise direction.

[0065] Thereby, as Figure 5 shown, the second latch 33 disengages from the second hook 32, and the second interlocking device 31 is unlocked.

[0066] Figure 6 is a front view of the car door device in the elevator device as viewed from the landing side. A car door frame 61 is fixed to the upper part of the car entrance 6a. A car door track 62 is provided on the car door frame 61. The car door track 62 is parallel and horizontal to the width direction of the car entrance 6a. The width direction of the car entrance 6a is a direction parallel to the opening and closing operation direction of the right car door 7a and the left car door 7b, and is the Figure 1 left-right direction. Figure 6

[0067] The right car door 7a and the left car door 7b each have a car door panel 63 and a car door hanger 64. Each car door hanger 64 is fixed to the upper part of the corresponding car door panel 63. The right car door 7a and the left car door 7b are suspended from the car door track 62 and perform opening and closing operations along the car door track 62.

[0068] ​A car door linkage mechanism (not shown) and a door motor (not shown) are provided on the car door frame 61. The car door linkage mechanism mechanically links the right car door 7a and the left car door 7b to each other. The output of the door motor is transmitted to the right car door 7a and the left car door 7b via the car door linkage mechanism. Thus, the right car door 7a and the left car door 7b perform opening and closing operations.

[0069] An unlocking mechanism 65 is provided on the left car door 7b. The unlocking mechanism 65 unlocks the first interlock device 21 during the opening operation of the first right landing door 8a and the first left landing door 8b. In addition, the unlocking mechanism 65 unlocks the second interlock device 31 during the opening operation of the second right landing door 9a and the second left landing door 9b.

[0070] The unlocking mechanism 65 has a door stop side door knife 66 and a door pocket side door knife 67. The door stop side door knife 66 and the door pocket side door knife 67 are provided on the car door panel 63 of the left car door 7b.

[0071] The door pocket side door knife 67 can move relative to the left car door 7b in the width direction of the car entrance 6a. By moving the door pocket side door knife 67 relative to the left car door 7b, the interval between the door stop side door knife 66 and the door pocket side door knife 67 changes.

[0072] A working mechanism 68 is provided on the car door frame 61 and the left car door 7b. The working mechanism 68 moves the door pocket side door knife 67 during the opening and closing operations of the left car door 7b.

[0073] During the opening and closing operations of the first right landing door 8a and the first left landing door 8b, the unlocking mechanism 65 clamps the first fixed side interlock roller 24 and the first movable side interlock roller 25 between the door stop side door knife 66 and the door pocket side door knife 67.

[0074] Thus, the first movable side interlock roller 25 moves along an arc centered on the rotation axis of the first fixed side interlock roller 24, and the first latch 23 rotates, unlocking the first interlock device 21. In addition, the first left landing door 8b can move integrally with the left car door 7b.

[0075] That is, when the left car door 7b performs an opening operation, the first movable side interlock roller 25 abuts against the unlocking mechanism 65 and is displaced relative to the first left landing door 8b, causing the first latch 23 to disengage from the first hook 22.

[0076] In addition, during the opening and closing operations of the second right landing door 9a and the second left landing door 9b, the unlocking mechanism 65 clamps the second fixed side interlock roller 44 and the second movable side interlock roller 45 between the door stop side door knife 66 and the door pocket side door knife 67.

[0077] Accordingly, the second movable-side interlocking roller 45 moves along an arc centered on the rotation axis of the second fixed-side interlocking roller 44, and the second latch 33 rotates, unlocking the second interlocking device 31. In addition, the second left landing door 9b can move integrally with the left car door 7b.

[0078] That is, when the left car door 7b performs an opening operation, the second movable-side interlocking roller 45 abuts against the unlocking mechanism 65 and is displaced relative to the support member 41, causing the second latch 33 to disengage from the second hook 32.

[0079] Figure 7 is schematically showing Figure 2 the position relationship between the first interlocking device 21 and Figure 6 the unlocking mechanism 65. When the car 6 stops at the first landing floor 51, the unlocking mechanism 65 faces the first interlocking device 21.

[0080] Figure 8 is schematically showing Figure 3 the position relationship between the second interlocking device 31 and Figure 6 the unlocking mechanism 65. When the car 6 stops at each second landing floor 52, the unlocking mechanism 65 faces the second interlocking device 31.

[0081] The difference in the installation height of the second movable-side interlocking roller 45 from the landing floor at each second landing floor 52 and the installation height of the first movable-side interlocking roller 25 from the landing floor at the first landing floor 51 is within a set range. The set range is a range smaller than the vertical dimension of the unlocking mechanism 65. Additionally, it is more preferable that the installation height of the second movable-side interlocking roller 45 is the same as the installation height of the first movable-side interlocking roller 25.

[0082] In such an elevator device, a support member 41 is provided above the second latch 33 and separated from the second latch 33. The support member 41 can move in a direction parallel to the opening and closing operation direction of the second left landing door 9b.

[0083] The second movable-side interlocking roller 45 is supported by the support member 41. When the second movable-side interlocking roller 45 abuts against the unlocking mechanism 65 and is displaced relative to the support member 41, the second latch 33 is disengaged from the second hook 32. A transmission mechanism 36 is provided between the second movable-side interlocking roller 45 and the second latch 33.

[0084] Therefore, both the first interlocking device 21 and the second interlocking device 31 with an installation height lower than that of the first interlocking device 21 can be unlocked by the shared unlocking mechanism 65. Accordingly, the limitation on the height dimension difference between multiple different landing entrances can be alleviated.

[0085] In addition, the first interlock device 21 and the second interlock device 31 are respectively arranged outside the landing door panel 13. Therefore, even when a glass window is provided on the landing door panel 13, the first interlock device 21 and the second interlock device 31 cannot be seen from the landing.

[0086] In addition, a guide body 34 is provided above the second landing entrance 52a. Therefore, the support member 41 and the second movable-side interlock roller 45 can be smoothly moved in a direction parallel to the opening and closing operation direction of the second left landing door 9b.

[0087] In addition, the transmission mechanism 36 has a second link 47 connected between the second fixed-side interlock roller 44 and the second latch 33. Therefore, the movement of the second fixed-side interlock roller 44 can be transmitted to the second latch 33 through a simple structure.

[0088] In addition, the first interlock device 21 may be arranged between the first right landing door 8a and the landing door frame 11, and the second interlock device 31 may be arranged between the second right landing door 9a and the landing door frame 11. In this case, the unlocking mechanism 65 is arranged on the right car door 7a.

[0089] In addition, the number of landing entrances with a large height dimension is not particularly limited, and may be two or more.

[0090] In addition, the number of landing entrances with a small height dimension is not particularly limited. For example, the height dimension of the landing entrance at the lowest floor may also be smaller than the height dimensions of the landing entrances other than the lowest floor.

[0091] In addition, there may be a variety of second interlock devices 31 with different distances between the second latch 33 and the support member 41, that is, different vertical dimensions of the transmission mechanism 36. In this case, as long as the first interlock device 21 and the second interlock device 31 can be unlocked by a common unlocking mechanism 65, the same effect as above can be obtained. Therefore, the number of modes of the height dimension of the landing entrance may also be three or more.

[0092] In addition, the car door device and the landing door device may also be single-opening door devices.

[0093] In addition, the number of door panels of the car door device and the landing door device may be 1, or may be 3 or more.

[0094] In addition, the layout of the elevator device is not limited to Figure 1 the layout. For example, the traction machine 3 may also be arranged at a position other than the top of the hoistway 1.

[0095] In addition, the elevator device may also be an elevator device with a machine room, a double-deck elevator, an elevator with a multi-car system in a single hoistway, etc. The multi-car system in a single hoistway is a system in which an upper car and a lower car disposed directly below the upper car are each independently lifted and lowered in a common hoistway.
