Description

  The present invention relates to an elevator apparatus having a plurality of hoistways provided in a building structure and a plurality of cars that are individually raised and lowered in each hoistway.

  Conventionally, for example, in an elevator apparatus provided in a super high-rise building or the like, an elevator apparatus dedicated to a lower floor has been installed in the lower layer portion of the building in order to shorten the lifting distance of the car disposed in the hoistway. An upper floor dedicated elevator apparatus may be separately installed in the upper layer portion (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 3-99863

  However, for example, when a passenger moves from a lower floor to an upper floor, in order to transfer from the lower floor dedicated elevator device to the upper floor dedicated elevator device, the passenger must first get down to the connecting floor. Therefore, it takes time and effort for the passengers to transfer due to movement on the transfer floor.

  The present invention has been made to solve the above-described problems, and an object thereof is to obtain an elevator apparatus that can reduce the time and effort of passengers for transit.

  The elevator apparatus according to the present invention includes a first hoistway and a second hoistway that are partially adjacent to each other, a first transfer opening that can be opened and closed, and is elevated and lowered in the first hoistway. A first car that can be stopped at a portion adjacent to the second hoistway in the hoistway and a second connecting port that can be opened and closed, and is raised and lowered in the second hoistway. A second car that can be stopped side by side with the first car in a portion adjacent to the first hoistway in the road, and the first transfer when the first car and the second car are stopped side by side The mouth and the second connecting port face each other, and the first car and the second car can communicate with each other through the first connecting port and the second connecting port.

  In the elevator apparatus according to the present invention, a part of each of the first hoistway and the second hoistway is adjacent to each other, and the first car and the second hoistway are moved up and down in the first hoistway. The second car to be moved up and down can be stopped side by side, and when the first car and the second car are stopped side by side, the inside of the first car and the inside of the second car can communicate with each other. Therefore, the passenger can transfer between the first car and the second car without getting off to the landing for the transfer, and the labor of the passenger for the transfer can be reduced.

The destination floor button devices 32 and 33 are electrically connected to the control device 11 (FIG. 2).

  The control device 11 outputs a drive command to the drive device 6 based on the input of a signal from any one of the lower floor buttons 32a and the transfer floor buttons 32c. The first car 9 is moved up and down to the selected destination floor by the driving of the driving device 6 by the input of the driving command. Further, the control device 11 outputs a drive command to the drive device 17 based on the input of a signal from any one of the lower floor buttons 33a and the transfer floor buttons 33c. The second car 20 is moved up and down to the selected destination floor by the driving of the driving device 17 by the input of the driving command.

  Furthermore, the control device 11 determines that both the second car 9 and the first car 20 are connected to the transit floor 2 based on the signal input from either the upper floor button 32b or the lower floor button 33a. A drive command is output to the drive devices 6 and 17 so as to land.

Next, the operation will be described.
When any one of the upper floor buttons 32b is selected (pressed) by the passenger in the first car 9, an operation signal is output to the control device 11 from the selected upper floor button 32b. Based on the input of this operation signal, a drive command is output from the control device 11 to the drive devices 6 and 17, and the drive devices 6 and 17 are driven. As a result, the first car 9 is raised in the lower hoistway 3, and the second car 20 is lowered in the upper hoistway 4. Thereafter, the first car 9 and the second car 20 are landed side by side on the connecting floor 2.

  Thereafter, the first connecting port 12 and the second connecting port 22 are opened in synchronization with each other according to a command from the control device 11, and the first car 9 and the second car 20 are communicated with each other. Thereby, the passenger can move from the first car 9 to the second car 20.

  Thereafter, the first transfer port 12 and the second transfer port 22 are closed in synchronization with a command from the control device 11. Thereafter, the driving device 17 is driven, and the second car 20 is moved up in the upper hoistway 4 and landed on the destination floor. Thereafter, the second car doorway 23 is opened according to a command from the control device 11, and passengers can move from the second car 20 to the landing side of the destination floor.

  When any one of the lower floor buttons 33a is selected (pressed) by the passenger in the second car 20, an operation signal is output to the control device 11 from the selected lower floor button 33a. In the same manner as described above, the first car 9 and the second car 20 are landed side by side on the transfer floor 2.

  Thereafter, the inside of the first car 9 and the inside of the second car 20 are communicated with each other in the same manner as described above, and passengers can move from the second car 20 into the first car 9.

  Thereafter, the first transfer port 12 and the second transfer port 22 are closed in synchronization with a command from the control device 11. Thereafter, the driving device 6 is driven, and the first car 9 is lowered in the lower hoistway 3 and landed on the destination floor. Thereafter, the first car doorway 13 is opened according to a command from the control device 11, and passengers can move from the first car 9 to the landing side of the destination floor.

  In such an elevator apparatus, the lower hoistway 3 and the upper hoistway 4 provided in the building structure are adjacent to each other on a common transfer floor, and the first car 9 and the second car 20 are arranged on the transfer floor 2. Since the inside of the first car 9 and the second car 20 can communicate with each other through the first connecting port 12 and the second connecting port 22 when landing on the floor, It is possible to transfer between the first car 9 and the second car 20 without getting off the landing, and it is possible to facilitate the passenger's transfer between the first car 9 and the second car 20. . It is possible to reduce the time and effort of passengers involved in the movement on the transfer floor 2.

  In addition, since the first car 9 has a first car entrance 13 that is separate from the first transfer port 12, passengers between the first car 9 and the landing floor 2 can be used. Getting on and off is possible. Accordingly, it is possible to prevent a decrease in the operation efficiency of the elevator apparatus.

  In addition, since the second car 20 has a second car entrance 23 separate from the second transfer port 22, passengers between the second car 20 and the landing floor 2 are located in the second car 20. Getting on and off is possible. Accordingly, it is possible to prevent a decrease in the operation efficiency of the elevator apparatus.

  In the above example, the engagement device for engaging the car doors 14 and 24 with each other synchronizes the opening and closing of the first connecting port 12 and the second connecting port 22. 12 and the second connecting port 22 can be individually opened and closed, and a command is output from the control device 11 to each of the first connecting port 12 and the second connecting port 22 so as to be opened and closed synchronously. It may be.

  In the above example, the lower hoistway 3 and the upper hoistway 4 are adjacent to each other on the connecting floor 2, but the lower hoistway 3 and the upper hoistway 4 may be adjacent to each other between the floors. In this case, the first car 9 and the second car 20 are stopped side by side between the floors where the lower hoistway 3 and the upper hoistway 4 are adjacent to each other. Therefore, when the first car 9 and the second car 20 are stopped side by side, only the connection between the first car 9 and the second car 20 is possible. That is, passengers in the first car 9 and the second car 20 cannot get on and off the floors.
