  In addition, the operation of the elevator by the control panel includes a normal operation mode in which the first car 4 and the second car 5 are moved up and down independently in all the lifting sections, and the first car 4 is stopped on the top floor, It is possible to switch between an expansion operation mode in which only the second car 5 is moved up and down in the lifting section excluding the top floor.

Next, the operation will be described.
During normal operation, the closing body 13 is displaced to the normal position, and the second car 5 is disposed outside the area of the first car 4 in the vertical projection plane of the hoistway 1. In other words, the first car 4 and the second car 5 can pass in the hoistway 1.

  For example, when carrying a large load or the like, first, the elevator operation mode is switched from the normal operation mode to the extended operation mode. As a result, as shown in FIG. 5, the first car 4 is stopped on the top floor, and the second car 5 is stopped on a floor different from the top floor.

  Thereafter, the respective rotating walls 22 are pushed outward from the inside of the car room 12 to rotate the respective rotating walls 22 to the outside of the car room 12. Thereby, the link structure 23 is extended, and the movable floor 24 and the movable ceiling 25 are pulled out to the outside of the cab 12. As a result, the closing body 13 is displaced from the normal position to the enlarged position, and becomes the car room enlarged portion 16.

  Thereafter, a large baggage or the like is carried into the second car 5 and transported to the destination floor. At this time, the destination floor is different from the top floor.

  After the transportation, the respective rotating walls 22 are rotated in the direction in which the link structure 23 is contracted, and the movable body 24 and the movable ceiling 25 are pulled back to the car room 12 side by pulling a string in the car room 12, thereby closing the closing body 13. Displace from the enlarged position to the normal position. Thereafter, the operation mode of the elevator is switched to the normal operation mode.

  In such an elevator apparatus, the second car 5 has a car room 12 provided with an opening 10 and a closing body 13 that closes the opening 10, and the closing body 13 is moved from the car room 12 to the car room. Since it can be displaced between the enlarged position protruding as the enlarged portion 16 and the normal position located on the cab side relative to the enlarged position, the size of the second car 5 can be changed as necessary. Can do. Therefore, for example, when a large device is arranged in the hoistway 1, the second car 5 can be lifted and lowered by reducing the second car 5 while avoiding the large device. Further, in a portion where no large-sized device is arranged, the carrying volume can be increased by enlarging the second car 5. For this reason, it is possible to prevent the space in the hoistway 1 from being expanded, and to increase the transport volume of the second car 5.

  Moreover, since the closing body 13 has a pair of rotation wall 22 and the link structure 23 connected between each rotation wall 22 and expand-contracted by rotation of each rotation wall 22, each rotation wall A portion facing the opening 10 of the cab expansion portion 16 can be easily formed simply by displacing the rim 22.

  Further, since the movable ceiling 25 can be reciprocally displaced with respect to the upper part of the opening 10, and the movable floor 24 can be reciprocated with respect to the lower part of the opening 10, the movable ceiling 25 and the movable floor 24 can be moved. By simply pulling out from the car room 12, the ceiling and floor of the car room expansion part 16 can be easily formed.

  Further, in the vertical projection plane of the hoistway 1, the closing body 13 partially overlaps the area of the first car 4 when it is at the enlarged position, and outside the area of the first car 4 when it is at the normal position. The first car 4 and the second car 5 can be moved up and down so that the first car 4 and the second car 5 can pass each other by displacing the closing body 13 to the normal position. By displacing to the enlarged position, the second car 5 can be enlarged to the area where the first car 4 is raised and lowered to increase the transport volume. Therefore, expansion of the space in the hoistway 1 can be prevented, and the transport volume of the second car 5 can be increased.

  In the above example, the stretchable body is the link structure 23, but may be a stretchable bellows body.

  In the above example, the engaging portion 31 that can be engaged with each rotating wall 22 is provided at the enlarged side end portion of the floor plate portion 30, but the lower end portion of each rotating wall 22 is slidably connected. A rail or a guide may be provided at the end of the floor plate 30 on the enlarged side. In this case, the rail or guide is arranged perpendicular to the direction in which the movable floor 24 is displaced. In this way, since each rotating wall 22 and the movable floor 24 are always connected, not only the rotation of each rotating wall 22 in the direction in which the link structure 23 is stretched but also the link structure 23 contracts. The movable floor 24 can also be displaced in conjunction with each rotating wall 22 by rotating each rotating wall 22 in the direction. Accordingly, it is possible to eliminate the trouble of separately displacing each rotating wall 22 and the movable floor 24, and it is possible to easily displace the movable floor 24 only by rotating each rotating wall 22.

  In the above example, the engaging portion 33 that can be engaged with each rotating wall 22 is provided at the enlarged side end portion of the ceiling plate portion 32, but the upper end portion of each rotating wall 22 is slidably connected. A rail or guide may be provided at the enlarged side end of the ceiling plate portion 32. In this case, the rail or guide is arranged perpendicular to the direction in which the movable ceiling 25 is displaced. In this way, similarly to the above, it is possible to eliminate the trouble of separately displacing the respective rotating walls 22 and the movable ceiling 25, and the movable ceiling 25 can be easily displaced simply by rotating the respective rotating walls 22. Can be made.

  Further, in the above example, the movable floor 24 and the movable ceiling 25 are displaced by pushing and rotating the respective rotating walls 22 to the outside of the car room 12, but each of the movable floor 24 and the movable ceiling 25 is displaced. A displacement device for displacing the vehicle may be mounted on the second car 5. As the displacement device, for example, a member connected to the movable floor 24 or the movable ceiling 25 (for example, a nut screwed to a bolt) is reciprocally displaced by rotation of a bolt driven by a motor, or the movable floor 24 or the movable ceiling 25 is attached. Examples include an air cylinder that reciprocally displaces a connected piston. In this way, the movable floor 24 and the movable ceiling 25 can be automatically reciprocated. Further, as described above, if each rotating wall 22 is slidably connected to the movable floor 24 or the movable ceiling 25 by a rail or a guide, the rotating wall 22 can be automatically rotated, and the car room. The trouble of pushing and pulling each rotating wall 22 from within 12 can be eliminated.

  In the above example, the first car 4 is stopped at the top floor during the operation in the expanded operation mode. However, as shown in FIG. 6, the first car 4 is at the bottom floor. It may be stopped. In this case, the second car 5 is moved up and down in the lifting section excluding the lowest floor. Further, the first car 4 may be stopped at the intermediate floor. In this case, the second car 5 is moved up and down in an up-and-down section (any one of the up-and-down sections above and below the intermediate floor) excluding the intermediate floor.

Embodiment 2. FIG.
FIG. 7 is a cross-sectional view of an essential part showing an elevator car according to Embodiment 2 of the present invention. In this example, the closing body 13 includes a movable floor 24 and a movable ceiling 25 shown in the first embodiment, a plate-like facing wall 41 that faces the opening 10 and can be displaced reciprocally with respect to the opening 10, and an opening. It has link structures 42 and 43 that are connected between the side portions 10a and 10b of the portion 10 and the opposing wall 41, and are elastic bodies that can be expanded and contracted by the displacement of the opposing wall 41. In addition, a window 44 in which a transparent material such as glass is fitted is provided at a portion (back surface portion) of the car room wall 20 facing the car doorway 11.

  The facing wall 41 is arranged so that the opening 10 is positioned inside in the projection plane in the front-end direction of the car doorway 11. Further, the opposing wall 41 is displaced to an enlarged position by being displaced in a direction away from the car room 12, and is displaced to a normal position by being displaced in a direction to approach the car room 12. Furthermore, the opposing wall 41 is a part of the cab expansion section 16 (a wall surface facing the opening 10 of the cab expansion section 16) when in the expansion position, and closes the opening 10 when in the normal position. The car room wall surface portion 17 is provided. Furthermore, the opposing wall 41 can be engaged with each of the engaging portion 31 and the engaging portion 33 (FIG. 2) by displacement in a direction away from the car chamber 12. Thereby, the movable floor 24 and the movable ceiling 25 (FIG. 2) are pulled out to the outside of the car room 12 in accordance with the displacement of the opposing wall 41 in the direction away from the car room 12, and are displaced to the enlarged position. ing. The side portion 10a is provided at a position farther from the car entrance 11 than the side portion 10b in the depth direction of the car room 12.

  The link structures 42 and 43 have the same configuration as the link structure 23 shown in the first embodiment. Further, the link structure 42 is contracted between the side portion 10 a and the opposing wall 41 by the displacement of the opposing wall 41 in a direction approaching the cab 12. The link structure 43 is contracted between the side portion 10 b and the opposing wall 41 by the displacement of the opposing wall 41 in a direction approaching the cab 12.

  Further, the link structures 42 and 43 are each extended by displacement of the opposing wall 41 in the direction away from the car room 12, and become a part of the car room facing part 16. In this example, the link structures 42 and 43 displaced to the enlarged position are a pair of side wall surfaces arranged between the car room 12 and the opposing wall 41 of the car room enlarged portion 16. Other configurations are the same as those in the first embodiment.

Next, the operation will be described.
During normal operation, the closing body 13 is displaced to the normal position, and the first car 4 and the second car 5 can pass each other in the hoistway 1 as in the first embodiment. .

  For example, when transporting a large load or the like, as in the first embodiment, after the elevator operation is switched from the normal operation mode to the expansion operation mode, the opposing wall 41 is pushed out from the inside of the cab 12 to the outside. As a result, the link structures 42 and 43 are extended, and the movable floor 22 and the movable ceiling 25 are pulled out to the outside of the cab 12. As a result, the closing body 13 is displaced from the normal position to the enlarged position, and becomes the car room enlarged portion 16.

Since the link structures 42 and 43 are connected between the walls 41 and can be expanded and contracted by the displacement of the opposing wall 41, when the closing body 13 is in the normal position, only one opposing wall 41 is placed in the cab. 12 can be exposed. Therefore, the number of seams between the walls can be reduced, and the design in the cab 12 can be improved.

  Moreover, since the link structure 42 which can be expanded-contracted is connected between the side part 10a and the opposing wall 41, even if the window 44 is provided in the back part of the cage | basket | chamber 12, a part of closure body 13 is a cab It can be prevented from being visible through the window 44 from the inside.

  In the above example, the lower end of the opposing wall 41 is engaged with the movable floor 24 and the upper end of the opposing wall 41 is engaged with the movable ceiling 25 due to the displacement of the opposing wall 41 in the direction away from the cab 12. However, the lower end of the opposing wall 41 may be fixed to the movable floor 24 and the upper end of the opposing wall 41 may be fixed to the movable ceiling 25.

  In the above example, the movable floor 24 and the movable ceiling 25 are displaced by pushing the opposing wall 41 to the outside of the cab 12. However, in order to displace each of the movable floor 24 and the movable ceiling 25. These displacement devices may be mounted on the second car 5. Further, if the lower end portion of the opposing wall 41 is fixed to the movable floor 24 and the upper end portion of the opposing wall 41 is fixed to the movable ceiling 25, either the movable floor 24 or the movable ceiling 25 may be displaced. The number of displacement devices can be reduced.
