The car door 61 closes the car side entrance 11 when the car 10 moves up and down. The car door 61 opens the car-side entrance 11 when the car 10 has landed on any floor 103 of the building 101. The car 10 is provided with a sensor (not shown) that detects the open / closed state of the car door 61. These sensors can input or transmit the detection result to the control panel 50.

  The engagement member 62 is attached to the floor 103 side of one of the car doors 61 among the pair of car doors 61. 2 and 3, the car door 61 to which the engaging member 62 is attached is mainly shown out of the pair of car doors 61, and the other car door 61 is partially omitted. . In the following, when the car door 61 is described, the car door 61 to which the engaging member 62 is attached will be described as an example. Further, the opening direction and the closing direction of the car door 61 in the following description are those of the car door 61 to which the engaging member 62 is attached.

  The engaging member 62 is integral with the car door 61 and can move in the opening direction and the closing direction. The engaging member 62 has a main body 62a and an engaging piece 62b. The main body 62a is formed in a strip shape and is arranged in a state extending in the vertical direction. The main body 62a is fixed to the car door 61 via a fixing member such as a bolt. The engagement piece 62b is provided so as to protrude from the one end side of the main body 62a toward the floor 103 in the opening direction and the closing direction of the car door 61. The engagement piece 62b is disposed between an engagement roller 75 and an engagement roller 76, which will be described later, when the car 10 is landed on the floor 103.

The abutting member 63 is disposed at a position that abuts against an engagement roller 76 described later in a state where the car door 61 is fully opened. The drive device 64 has a drive source (not shown) such as a motor device. The drive device 64 is controlled by, for example, a drive control unit 51 provided in the control panel 50 or the like.

  The landing door device 70 includes a landing door 71 and an interlock mechanism 72. In addition, illustration of the landing door apparatus 70 is abbreviate | omitted in FIG. The landing door 71 closes the floor side entrance 111 of the floor 103. A pair of landing doors 71 are provided on the left and right so as to cover the floor side entrance 111. The pair of landing doors 71 are provided so as to be movable in conjunction with each other in opposite directions by a link mechanism (not shown). The pair of landing doors 71 are arranged side by side in the depth direction with respect to the car door 61 when the car 10 reaches the floor 103. The depth direction is a direction perpendicular to the opening direction and the closing direction of the car door 61 and the landing door 71 and perpendicular to the vertical direction. The pair of landing doors 71 move in the opening direction and the closing direction in conjunction with the car door 61 to open and close the floor side entrance 111. In FIG. 3, of the pair of landing doors 71, the landing door 71 facing the car door 61 to which the engagement member 62 is attached is mainly shown, and the other landing door 71 is omitted. In the following description, when the landing door 71 is described, the landing door 71 facing the car door 61 to which the engaging member 62 is attached will be described as an example.

  The interlock mechanism 72 locks the landing door 71 in a closed state. In addition, when the car door 61 of the car 10 that has landed on the floor 103 is opened, the interlock mechanism 72 releases the lock in conjunction with the movement of the car door 61. FIG. 4 shows a state where the landing door 71 is locked. As shown in FIG. 4, the interlock mechanism 72 includes a rotation lever 73, a locking member 74, and engagement rollers 75 and 76. The rotation lever 73 is supported by a bearing 77 so as to be rotatable in the direction around the axis parallel to the depth direction. The bearing 77 is fixed to the landing door 71. Therefore, the rotation lever 73 moves integrally with the landing door 71 in the opening direction and the closing direction.

  The rotation lever 73 is branched into a first portion 73a and a second portion 73b at a branching portion. A hook 73c is formed at the tip of the first portion 73a. The locking member 74 is fixed to a fixing member (not shown) on the landing door device 70 side. A hook locking portion 74 c is formed on the locking member 74.

  The engagement roller 75 is attached to the first portion 73 a of the rotation lever 73. Further, the engagement roller 76 is attached to the second portion 73 b of the rotation lever 73. The engaging rollers 75 and 76 are provided so as to protrude from the rotary lever 73 toward the hoistway 102. The engagement roller 75 is engaged with the engagement piece 62b of the engagement member 62 when the car door 61 is closed. The engagement roller 76 is engaged with the engagement piece 62b when the car door 61 is opened.

  As shown in FIG. 4, when the landing door 71 is closed, the hook 73 c of the rotation lever 73 is engaged with the hook locking portion 74 c of the locking member 74. In this case, the landing door 71 is locked in a closed state. Further, when the car 10 is landed on the floor 103, the engagement piece 62 b of the engagement member 62 is disposed between the engagement roller 75 and the engagement roller 76 as shown by a one-dot chain line portion in FIG. 4. Is done.

  When the car door 61 is opened in this state, the engaging member 62 moves in the opening direction integrally with the car door 61. As the engagement member 62 moves, the engagement piece 62b pushes the engagement roller 76 in the opening direction. Thereby, as shown in FIG. 5, the rotation lever 73 rotates, and the hook 73c is detached from the hook engaging portion 74c. For this reason, the lock of the landing door 71 is released.

  Thereafter, when the car door 61 further moves in the opening direction, the engaging member 62 moves together with the car door 61, and the engaging roller 76 is pushed by the engaging piece 62b. As a result, the landing door 71 is pushed together with the engagement roller 76 in the opening direction, and opens in conjunction with the car door 61. When the car door 61 and the landing door 71 are fully opened, the engagement roller 76 is brought into contact with the contact member 63 as shown in FIG. For this reason, the engagement roller 76 is sandwiched between the engagement piece 62b and the contact member 63.

  FIG. 7 is a diagram showing in more detail a state where the engagement roller 76 is sandwiched between the engagement piece 62b and the contact member 63. For example, when a vertical force is applied to the car 10, a vertical force is also applied to the engaging member 62 and the abutting member 63 integrally with the car 10. From the state shown in FIG. 7, for example, when a force acts on the car 10 in the upward direction (indicated by a white arrow in FIG. 7), the engagement roller 76 has an engagement piece 62 b and a contact member 63. Each is given an upward force. For this reason, the engaging piece 62b and the contact member 63 receive downward frictional force from the engaging roller 76, respectively. Due to this frictional force, the upward movement of the engagement piece 62b and the contact member 63 is suppressed. Therefore, the upward movement of the car 10 is suppressed.

  Further, for example, when a downward force is applied to the car 10 (indicated by a black arrow in FIG. 7), a downward force is applied to the engagement roller 76 from the engagement piece 62 b and the contact member 63. Is granted. For this reason, the engagement piece 62b and the contact member 63 receive upward frictional force from the engagement roller 76, respectively. Due to this frictional force, the downward movement of the engagement piece 62b and the contact member 63 is suppressed. Therefore, the downward movement of the car 10 is suppressed.

  In this way, the engagement roller 76 is sandwiched between the engagement member 62 and the contact member 63 provided integrally with the car 10 in the direction parallel to the opening direction and the closing direction, so that the car 10 is moved in the vertical direction. Movement is suppressed. For this reason, even when a vertical force is applied to the car 10, the vibration of the car 10 is suppressed.

  Note that the drive control unit 51 may drive the drive device 64 so that the car door 61 moves further in the opening direction from the fully opened position. As a result, the force acting in the opening direction from the engagement piece 62b to the engagement roller 76 is increased, so that the force for sandwiching the engagement roller 76 with the contact member 63 is increased. Thereby, the vibration to the up-down direction of the passenger car 10 is reduced.

  As described above, according to the first embodiment, the contact member 63 provided in the car door device 60 is connected to the engagement roller 76 which is a part of the interlock mechanism 72 in a state where the car door 61 and the landing door 71 are opened. Abutted. The contact member 63 suppresses the movement of the engagement roller 76 in the vertical direction. Thus, even when a vertical force is applied to the car 10 such as when an occupant gets on and off, vibration of the car 10 is suppressed.

[Embodiment 2]
Next, Embodiment 2 will be described. In the second embodiment, since the configuration of the contact member is different from that of the first embodiment, the description will focus on the differences. Other configurations are the same as those in the first embodiment. FIG. 8 is a diagram illustrating an example of a part of the door device 180 according to the second embodiment. As shown in FIG. 8, a pair of contact members 163 are provided at positions where the engaging roller 76 is sandwiched in the vertical direction.

  The contact member 163 is fixed to a part of the car door device 60 and provided integrally with the car 10. The contact member 163 is formed in a plate shape, for example, and is arranged in parallel with the horizontal direction. The contact member 163 is disposed at a position where the contact member 163 contacts the upper end and the lower end of the engagement roller 76 in a state where the car door 61 and the landing door 71 are fully opened, for example. When the contact member 163 contacts the upper end and the lower end of the engagement roller 76, the contact member 163 and the engagement roller 76 are engaged in the vertical direction.

  In the state shown in FIG. 8, for example, when a force acts on the car 10 in the vertical direction, a vertical force acts on the engagement roller 76 from the contact member 163. On the other hand, since the contact member 163 and the engagement roller 76 are engaged in the vertical direction, the movement of the contact member 163 in the vertical direction is suppressed. For this reason, even when a vertical force is applied to the car 10, the vibration of the car 10 is suppressed.

  FIG. 9 is a view showing a door device 180 according to a modification. As shown in FIG. 9, the contact member 163 is not limited to a configuration fixed to a part of the car door device 60, and is configured to be connected to a damping mechanism 165 such as a damper 165 a and an elastic member 165 b, for example. It may be. In this configuration, the damping mechanism 165 attenuates the vertical vibration of the engagement roller 76 via the contact member 163. Thereby, when a vertical force is applied to the car 10, vibration generated in the car 10 can be attenuated.

[Embodiment 3]
Next, Embodiment 3 will be described. Since the third embodiment is different from the first embodiment in that it has a moving mechanism that moves the contact member, the description will focus on the differences. Other configurations are the same as those in the first embodiment. 10 and 11 are diagrams illustrating an example of the door device 280 according to the third embodiment. As illustrated in FIG. 10, the car door device 260 of the door device 280 includes a contact member 263 and a guide mechanism 264 that is an example of a moving mechanism. The contact member 263 is connected to the guide mechanism 264. The guide mechanism 264 moves the contact member 263 in the depth direction according to the amount of movement of the car door 61 and the landing door 71 in the opening direction. The guide mechanism 264 includes a rotating member 265, a roller 266, a guide 267, and a pressing mechanism 268.

  The rotating member 265 is formed in a straight bar shape and has a first end 265a and a second end 265b. The first end portion 265a of the rotating member 265 is connected to the car door 61 via the shaft member 265c. The shaft member 265c has a central axis parallel to the vertical direction. The rotating member 265 is provided so as to be rotatable in the direction around the axis of the central axis of the shaft member 265c. The rotating member 265 moves in the opening direction and the closing direction integrally with the car door 61 via the shaft member 265c. The second end portion 265b of the rotation member 265 is connected to the contact member 263 via the shaft member 265d. The shaft member 265d has a central axis parallel to the vertical direction. The contact member 263 is supported so as to be rotatable about the axis of the central axis of the shaft member 265d.

  The roller 266 is attached to the contact member 263. The roller 266 is provided to be rotatable in a direction around the axis of rotation that is parallel to the vertical direction. The guide 267 guides the roller 266. The guide 267 is fixed to a part of the car 10 independently of the car door 61. Therefore, when the car door 61 opens, the car door 61 moves independently with respect to the guide 267.

  The guide 267 is disposed above the car door 61. The guide 267 includes a first guide part 267a, a second guide part 267b, and a third guide part 267c. The first guide part 267a, the second guide part 267b, and the third guide part 267c are arranged in order along the moving direction of the car door 61. The first guide part 267 a and the third guide part 267 c are arranged in parallel to the moving direction of the car door 61. The first guide portion 267 a is disposed on the inner side of the car 10 with respect to the car door 61. The third guide portion 267 c is disposed on the floor 103 side with respect to the car door 61. The second guide portion 267 b is disposed to be inclined with respect to the moving direction of the car door 61. The second guide part 267b is arranged so as to straddle the car door 61 from the first guide part 267a to the third guide part 267c.

  The pressing mechanism 268 applies an elastic force to the first end portion 265 a of the rotating member 265. The pressing mechanism 268 is fixed to a part of the car door 61, for example. The elastic force by the pressing mechanism 268 is applied to the floor 103 side with respect to the first end portion 265a. Therefore, a force acts on the rotating member 265 counterclockwise in FIG. 10 about the shaft member 265c. With this force, the roller 266 is pressed against the guide 267. For this reason, when the car door 61 moves, the roller 266 can move along the guide 267.

  In the contact member 263 configured as described above, when the car door 61 in the closed state is opened, the rotating member 265, the contact member 263, and the roller 266 move together. The roller 266 is guided to the first guide part 267a, the second guide part 267b, and the third guide part 267c of the guide 267 according to the movement amount of the car door 61. When the roller 266 is guided by the first guide portion 267a, the abutting member 263 has the rotating member 265 arranged in parallel with the moving direction of the car door 61 as shown in FIG.

  When the car door 61 is further opened, the roller 266 is guided to the third guide part 267c via the second guide part 267b. In this case, as shown in FIG. 11, the abutting member 263 rotates the rotating member 265 clockwise about the shaft member 265c in FIG. Protrusively. The contact member 263 is disposed on the moving path of the engagement roller 76. The abutting member 263 is disposed at a position where it abuts on the engaging roller 76 when the landing door 71 is fully opened by adjusting the inclination angle and position of the second guide portion 267b of the guide 267 in advance. Is done. For this reason, when the landing door 71 is fully opened, the engagement roller 76 is sandwiched between the engagement piece 62b and the contact member 263.

  As described above, according to the third embodiment, when the engagement roller 76 is sandwiched between the engagement member 62 and the contact member 263 that are provided integrally with the car 10, the car 10 is moved in the vertical direction. Is suppressed. For this reason, even when the vertical force of the car 10 is applied, the vibration of the car 10 is suppressed.

[Embodiment 4]
Next, a fourth embodiment will be described. In the fourth embodiment, the configuration of the abutting member and the moving mechanism is different from that of the third embodiment, and therefore, differences will be mainly described. 12 and 13 are diagrams illustrating an example of the door device 380 according to the fourth embodiment. FIG. 12 shows the door device 380 viewed from above, and FIG. 13 shows the door device 380 viewed from the floor side.

  As shown in FIG. 12, a guard 390 is provided on the landing door device 370. The guard 390 is provided to prevent the rope such as the main rope 30 from being caught by the engagement roller 76, the engagement member 62, or the like. The guard 390 is disposed below the engagement roller 76, for example. A plate-like shoe portion 391 is formed at each end of the guard 390 in the opening direction and the closing direction.

  As shown in FIG. 12, the car door device 360 includes a contact member 363 and a link mechanism 364 that is an example of a moving mechanism. The contact member 363 is connected to the engagement member 62 via the link mechanism 364. The link mechanism 364 moves the contact member 363 between the first position P1 and the second position P2 in conjunction with the movement of the car door 61. Specifically, the link mechanism 364 places the contact member 363 at the first position P1 when the car door 61 is in the fully closed state. The first position P1 is a position away from the shoe portion 391 of the guard 390. Further, the link mechanism 364 places the contact member 363 at the second position P2 when the car door 61 is in the fully open state. The second position P2 is a position in contact with the shoe portion 391.

  With such a configuration, when the car door 61 and the landing door 71 are fully opened, one shoe portion 391 of the guard 390 is brought into contact with the engagement piece 62b of the engagement member 62 as shown in FIG. The other shoe portion 391 comes into contact with the contact member 363. Therefore, the guard 390 is sandwiched between the engagement piece 62b and the contact member 363.

  Therefore, when a vertical force is applied to the car 10, a frictional force is generated between each shoe portion 391, the engagement piece 62b, and the contact member 363. Due to this frictional force, the vertical movement of the engagement piece 62b and the contact member 363 is suppressed. Therefore, the vertical vibration of the car 10 is suppressed.

  As described above, according to the fourth embodiment, the vertical movement of the car 10 is suppressed by sandwiching the guard 390 between the engaging member 62 and the contact member 363 provided integrally with the car 10. Is done. For this reason, even when the vertical force of the car 10 is applied, the vibration of the car 10 is suppressed.
