Next, operation modes of the elevator device will be described with reference to FIG. 5.

FIG. 5 is a diagram for operation modes of the elevator device according to Embodiment 1 of the present invention.

In FIG. 5, block 29a corresponds to a normal operation mode. Block 29b corresponds to a signal device operation mode. Block 29c corresponds to an evacuation operation mode. Block 29d corresponds to a forced return operation mode. For example, an operation mode transitions on the basis of a status of detection by a signal device, a status of the evacuation operation mode request switches 15 and a status of the forced return operation mode request switch 20.

For example, the signal device detects a state in which evacuation is needed because of, e.g., a fire. For example, an evacuation operation mode request switch 15 outputs a signal corresponding to an evacuation operation mode request to the controller when the evacuation operation mode request switch 15 is operated via, e.g., a key carried by e.g., the evacuation guide member 6a. For example, the forced return operation mode request switch 20 outputs a signal corresponding to a forced return operation mode request when the forced return operation mode request switch 20 is operated via, e.g., a key carried by a firefighter.

In FIG. 5, arrow 30a indicates that the operation mode transitions from the normal operation mode to the signal device operation mode. Arrow 30b indicates that the operation mode transitions from the normal operation mode to the evacuation operation mode. Arrow 30c indicates that the operation mode transitions from the normal operation mode to the forced return operation mode.

Arrow 30d indicates that the operation mode transitions from the signal device operation mode to the normal operation mode. Arrow 30e indicates that the operation mode transitions from the signal device operation mode to the evacuation operation mode. Arrow 30f indicates that the operation mode transitions from the signal device operation mode to the forced return operation mode.

Arrow 30g indicates the operation mode transitions from the evacuation operation mode to the normal operation mode. Arrow 30h indicates that the operation mode transitions from the evacuation operation mode to the signal device operation mode. Arrow 30i indicates that the operation mode transitions from the evacuation operation mode to the forced return operation mode.

Arrow 30j indicates that the operation mode transitions from the forced return operation mode to the normal operation mode. Arrow 30k indicates that the operation mode transitions from the forced return operation mode to the signal device operation mode. Arrow 30l indicates that the operation mode transitions from the forced return operation mode to the evacuation operation mode.

In a normal operation mode, a user on a hall 2 presses an operation button according to a direction that the user wishes to move. For example, the user presses the up button 10a if the user wishes to move to an upper floor. For example, the user presses the down button 11a if the user wishes to move to a lower floor. Here, the controller moves the car 3 to the floor on which the hall 2 in which the relevant operation has been performed exists. Subsequently, the controller opens the doors 8c, etc. Consequently, the user can get on the car 3. Subsequently, the user designates a destination floor via an operation button 25 on the car operating panel 24. The controller moves the car 3 to the destination floor. Subsequently, the controller opens the doors 8c, etc. Consequently, the user can get out of the car 3.

In a signal device operation mode, the controller does not respond to car calls. In this case, the controller forcibly moves the car 3 to the evacuation floor 5. Upon arrival of the car 3 to the evacuation floor 5, the controller opens the doors 8b and 8c for a preset period of time. Here, the controller guides users in the car 3 to the outside of the car 3. For example, the controller guides the users in the car 3 to the outside of the car 3 by means of an announcement. For example, the controller guides the users in the car 3 to the outside of the car 3 by means of chiming. For example, the controller guides the user in the car 3 to the outside of the car 3 by means of temporarily turning off lighting in the car 3. Subsequently, after a lapse of the preset period of time, the controller closes the doors 8b and 8c.

In an evacuation operation mode, the controller does not respond to car calls. In this case, the controller forcibly moves the car 3 to the evacuation floor 5. Upon arrival of the car 3 to the evacuation floor 5, the controller opens the doors 8b and 8c for a preset period of time. Here, the controller guides users in the car 3 to the outside of the car 3. For example, the controller guides the users in the car 3 to the outside of the car 3 by means of an announcement. For example, the controller guides the users in the car 3 to the outside of the car 3 by means of chiming. For example, the controller guides the users in the car 3 to the outside of the car 3 by temporarily turning off the lighting in the car 3. Subsequently, after a lapse of the preset period of time, the controller closes the doors 8b and 8c.

Subsequently, the controller moves the car 3 to the rescue floor on which the evacuation operation mode request switch 15 has been operated (for example, the rescue floor 4a). Upon arrival of the car 3 to the rescue floor, the controller opens the doors 8a and 8c. Here, the evacuation guide member of the rescue floor (for example, the evacuation guide member 6a) guides evacuees (for example, the evacuees 7a) to the inside of the car 3.

Here, the operation buttons in the hall 2 on the rescue floor function as an operation control device. For example, upon the evacuation guide member pressing an operation button in the hall 2, the controller closes the doors 8a and 8c. After that, the car 3 does not respond to car calls. Subsequently, the controller forcibly moves the car 3 to the evacuation floor 5. Upon arrival of the car 3 to the evacuation floor 5, the controller opens the doors 8b and 8c for a preset period of time. Here, the controller guides the users in the car 3 to the outside of the car 3. For example, the controller guides the users in the car 3 to the outside of the car 3 by means of an announcement. For example, the controller guides the users in the car 3 to the outside of the car 3 by means of chiming. For example, the controller guides the users in the car 3 to the outside of the car 3 by means of temporarily turning off the lighting in the car 3. Subsequently, after a lapse of the preset period of time, the controller closes the doors 8b and 8c.

Subsequently, the controller moves the car 3 to the rescue floor on which the evacuation operation mode request switch 15 has been operated (for example, the rescue floor 4a) again. The movement between the rescue floor and the evacuation floor 5 continues until the operated state of the evacuation operation mode request switch 15 on the rescue floor is cancelled.

Here, e.g., the position indicator 12a of each hall 2 functions as a rescue floor indicator. In this case, e.g., the position indicator 12a of each hall 2 indicates a floor number of the rescue floor on which the evacuation operation mode request switch 15 has been operated. The floor number of the rescue floor on which the evacuation operation mode request switch 15 has been operated may be indicated by, e.g., the position indicator 12a and the like only in the hall 2 on each of the rescue floors 4a to 4c and the hall 2 on the evacuation floor 5. If the car 3 is moving, e.g., the movement direction indicator 13a in each hall 2 indicates a direction of the movement of the car 3.

Upon the evacuation guide member cancelling the operated state of the evacuation operation mode request switch 15 on the rescue floor, the car stops moving between the rescue floor and the evacuation floor 5. If an evacuation operation mode request switch 15 is subsequently operated on a rescue floor that is different from the rescue floor, the controller executes an evacuation operation mode that is different from the evacuation operation mode. More specifically, the controller executes an evacuation operation mode in which the car 3 moves between the rescue floor on which the evacuation operation mode request switch 15 has been operated and the evacuation floor.

For a priority order of the rescue floors, it is possible that an order of each evacuation operation mode request switch 15 being operated is stored in a memory and the priority order is set on the basis of the order. It is also possible that after end of an evacuation operation mode for one rescue floor, an evacuation operation mode is preferentially set for a higher rescue floor. It is also possible that after end of an evacuation operation mode for one rescue floor, an evacuation operation mode is preferentially set for a lower rescue floor. An evacuation operation mode may preferentially be set for a rescue floor requiring more time for evacuation. More specifically, an evacuation operation mode may preferentially be set for a rescue floor that is farther from the evacuation floor 5.

In a forced return operation mode, the controller forcibly moves the car 3 to the evacuation floor 5. Upon arrival of the car 3 to the evacuation floor 5, the controller opens the doors 8b and 8c for a preset period of time. Here, the controller guides users in the car 3 to the outside of the car 3. For example, the controller guides the users in the car 3 to the outside of the car 3 by means of an announcement. For example, the controller guides the users in the car 3 to the outside of the car 3 by means of chiming. For example, the controller guides the users in the car 3 to the outside of the car 3 by temporarily turning off the lighting in the car 3.

Next, statuses of the no-entry indicators 17 and 22, etc., will be described with reference to FIG. 6.

FIG. 6 is a diagram for describing statuses of no-entry indicators, etc., in the elevator device according to Embodiment 1 of the present invention.

In FIG. 6, “Running mode” indicates operation modes. “No-entry” indicates status of the no-entry indicators 17 and 22. “EV-sign 1” indicates a status of the evacuation guidance indicators 18. “EV-sign 2” indicates a status of the evacuation guidance indicator 28. “EV-sign 3” indicates a status of the use state indicator 23. “Intercom” indicates a status of the report devices 16, 21 and 27.

In this case, the no-entry indicators 17 and 22 provide no indication. The evacuation guidance indicators 18 provide no indirection. The evacuation guidance indicator 28 provides no indication. The use state indicator 23 provides no indication. The report devices 16, 21 and 27 operate normally. For example, when a user is trapped in the car 3, the user can press the intercommunication button 27a and communicate with the outside through, e.g., a telephone line by means of the speaker microphone 27b.

A status in a signal device operation mode indicates “Alarm” on the “Running mode” row. In this case, the no-entry indicators 17 and 22 indicate that use of the elevator is prohibited. The evacuation guidance indicators 18 indicate that the car 3 can be used for evacuation. The evacuation guidance indicator 28 indicates that the car 3 can be used for evacuation. The use state indicator 23 indicates that the car 3 is in use for evacuation. The report devices 16, 21 and 27 operate normally. For example, when a user is trapped in the car 3, the user can press the intercommunication button 27a and communicate with the outside through, e.g., a telephone line by means of the speaker microphone 27b.

A status in an evacuation operation mode is indicated in “Fire Warden” on the “Running mode” row. In this case, the no-entry indicators 17 and 22 provide no indication. The evacuation guidance indicators 18 indicate that the car 3 can be used for evacuation. The evacuation guidance indicator 28 indicates that the car 3 can be used for evacuation.

It is possible to allow intercommunication to be performed among many sites including a building manager room of the building and a machine room of the elevator device.

A status in a forced return operation mode indicates “Call back” on the “Running mode” row. In this case, the no-entry indicators 17 and 22 indicate that use of the elevator is prohibited. The evacuation guidance indicators 18 provide no indication. The evacuation guidance indicator 28 provides no indication. The use state indicator 23 provides no indication. The operation of the report devices 16, 21 and 27 is switched to evacuation intercommunication operation. In this case, pressing the intercommunication button 16a or the like on any of the rescue floors 4a to 4c, the evacuation floor 5 and inside the car 3 enables intercommunication among the rescue floors 4a to 4c, the evacuation floor 5 and the inside of the car 3 using the speaker microphones 16b and the like. It is also possible to allow intercommunication to be performed among many sites including the building manager room of the building and the machine room of the elevator device.

Next, operation of the elevator device will be described with reference to FIGS. 7 to 10.

FIG. 7 is a flowchart for describing operation of the elevator device according to Embodiment 1 of the present invention in a normal operation mode. FIG. 8 is a flowchart for describing operation of the elevator device according to Embodiment 1 of the present invention in a signal device operation mode.

In the normal operation mode in FIG. 7, in step S1, the controller determines whether or not the signal device is actuated. If the signal device is not actuated in step S1, the operation proceeds to step S2. In step S2, the controller determines whether or not there is an evacuation operation mode request.

If there is no evacuation operation mode request in step S2, the operation proceeds to step S3. In step S3, the controller determines whether or not there is a forced return operation mode request. If there is no forced return operation mode request in step S3, the operating proceeds to step S4.

In step S4, the controller maintains the normal operation mode. In this case, the controller repeats the determination in step S1 in a preset cycle. Here, the operation may be returned to step S1 by means of an interrupt action.

If the signal device is actuated in step S1, the operation proceeds to step S5. In step S5, the controller changes the operation mode to a signal device operation mode. If there is an evacuation operation mode request in step S2, the operation proceeds to step S6. In step S6, the controller changes the operation mode to an evacuation operation mode. If there is a forced return operation mode request in step S3, the operation proceeds to step S7. In step S7, the controller changes the operation mode to a forced return operation mode.

In the signal device operation mode in FIG. 8, in step S11, the controller determines whether or not the signal device is actuated. If the signal device is actuated in step S11, the operation proceeds to step S12. In step S12, the controller determines whether or not there is an evacuation operation mode request.

If there is no evacuation operation mode request in step S12, the operation proceeds to step S13. In step S13, the controller determines whether or not there is a forced return operation mode request. If there is no forced return operation mode request in step S13, the operation proceeds to step S14.

If the signal device is not actuated in step S11, the operation proceeds to step S15. In step S15, the controller changes the operation mode to a normal operation mode. If there is an evacuation operation mode request in step S12, the operation proceeds to step S16. In step S16, the controller changes the operation mode to an evacuation operation mode. If there is a forced return operation mode request in step S13, the operation proceeds to step S17. In step S17, the controller changes the operation mode to a forced return operation mode.

In the evacuation operation mode in FIG. 9, in step S21, the controller determines whether or not there is an evacuation operation mode request. If there is an evacuation operation mode request in step S21, the operation proceeds to step S22. In step S22, the controller determines whether or not there is a forced return operation mode request.

If there is no forced return operation mode request in step S22, the operation proceeds to step S23. In step S23, the controller maintains the evacuation operation mode. In this case, the controller repeats the determination in step S21 in a preset cycle. The operation may be returned to step S21 by means of an interrupt action.

If there is no evacuation operation mode request in step S21, the operation proceeds to step S24. In step S24, the controller determines whether or not the signal device is actuated. If the signal device is actuated in step S24, the operation proceeds to step S25. In step S25, the controller changes the operation mode to a signal device operation mode.

If the signal device is not actuated in step S24, the operation proceeds to step S26. In step S26, the controller changes the operation mode to a nearest floor stoppage operation mode. In this case, the car 3 temporarily stops at a nearest floor. Subsequently, the operation proceeds to step S27, and the controller changes the operation mode to a normal operation mode.

If there is a forced return operation mode request in step S22, the operation proceeds to step S28. In step S28, the controller changes the operation mode to a forced return operation mode.

In the forced return operation mode in FIG. 10, in step S31, the controller determines whether or not there is a forced return operation mode request. If there is a forced return operation mode request in step S31, the operation proceeds to step S32. In step S32, the controller maintains the forced return operation. In this case, the controller repeats the determination in step S31 in a preset cycle. The operation may be returned to step S31 by means of an interrupt action.

If there is no forced return operation mode request in step S31, the operation proceeds to step S33. In step S33, the controller determines whether or not there is an evacuation operation mode request. If there is an evacuation operation mode request in step S33, the operation proceeds to step S34. In step S34, the controller changes the operation mode to an evacuation operation mode.

If there is no evacuation operation mode request in step S33, the operation proceeds to step S35. In step S35, the controller determines whether or not there is a signal device operation mode request. If there is a signal device operation mode request in step S35, the operation proceeds to step S36. In step S36, the controller changes the operation mode to a signal device operation mode.

If there is no signal device operation mode request in step S35, the operation proceeds to step S37. In step S37, the controller changes the operation mode to a nearest floor stoppage operation mode. Subsequently, the operation proceeds to step S38, and the controller changes the operation mode to a normal operation mode.

According to Embodiment 1 described above, if an evacuation operation mode request switch 15 is kept in an operated state, the car 3 continues movement between the relevant rescue floor and the evacuation floor 5. Here, the car 3 continuously stops at the relevant rescue floor until an evacuation guide member performs a preset operation. Thus, an efficiency of evacuation of a large number of users from the relevant rescue floor can be enhanced. As a result, people left in the building can efficiently be evacuated.

Here, the doors 3a and 3c are continuously opened until a predetermined operation is performed. Thus, a larger number of users can easily be guided to the car 3.

Also, in each hall 2, a floor number of the relevant rescue floor is indicated. Thus, users in each hall 2 can recognize a hall 2 used for evacuation using the car 3. Here, a direction of movement of the car 3 is also indicated. In other words, in each hall 2, an evacuation operation status is indicated in detail. Thus, chaos during evacuation can be prevented.

Also, in the hall 2 on each rescue floor or inside the car 3, it is indicated that the car 3 can be used for evacuation. Thus, users can evacuate in relief using the car 3.

Also, in the hall of the evacuation floor 5, it is indicated that the car 3 is in use for evacuation. Thus, firefighters can recognize that evacuation guidance using the car 3 is properly performed.

Also, on the rescue floor, the evacuation floor 5 and inside the car 3, the report devices 16 and the like are provided. Thus, evacuation guide members, firefighters and users can communicate with one another. As a result, chaos during evacuation can be prevented.

Also, when the forced return operation mode request switch 20 is operated, the car 3 returns to the evacuation floor 5. Thus, a firefighter can stop or resume an evacuation operation mode depending on the situation.

Also, in a hall on each of floors other than the rescue floors, a no-entry indicator indicating that no entry to the car is allowed in an evacuation operation mode may be provided. In this case, in the halls, users can recognize that users cannot evacuate using the car 3.

Also, a monitor may be provided in each of the report devices 16 and the like. In this case, in a normal operation mode, e.g., information on the inside of the building, promotions and advertisements may be indicated on the monitors. When operation of the report devices 16 and the like is switched to evacuation intercommunication operation, information to be shared for evacuation guidance, by the evacuation guide members 6a to 6c deployed at a plurality of spots in the building may be indicated on the monitors. For example, an image taken by a camera provided on an evacuation route, a landing entrance of the elevator and the like may be indicated on the monitors. For example, an image of, e.g., an evacuation guide member 6 who is engaging in intercommunication or an image of the periphery taken by a camera provided in the vicinity of a report device 16 or the like may be indicated on the monitors. For example, these images may be indicated on the monitors while the images being automatically switched from one to another.
