  Further, since the guide light 16 is installed on the ceiling 15 near the entrance of the car 10, the light of the guide light 16 can be visually recognized by the user at the landing 30 where the car 10 is landing. It is possible. For this reason, when the door opening extension button 26 is pressed, the control device 50 turns on the guide light 16 to turn on the guide light 16 so that the control car 50 is in the landing 30 where the car 10 is landing. The person is also informed that the door is extended. As a result, the elevator user at the landing 30 on the floor where the car 10 is currently landing is in the state where the opening time of the elevator door 5 is extended. It can be recognized by the guide light 16 that the car 10 is running. For this reason, when the door opening time of the elevator door 5 is left extended, a user at the landing 30 where the car 10 is landing gets into the car 10 and opens the door. By pressing the button 26, the open / close state of the elevator door 5 can be returned to the normal state.

  When the time set by the door opening extension function elapses during the extension of the door opening time or when the door opening extension button 26 is pressed, the door opening extension function is terminated and the elevator door 5 is closed. In this case, the control device 50 turns off the lit guide lamp 16. In this case, the display indicating that the door is being extended is also terminated by turning off the door opening extension display unit 43 in a state where the door opening extension is being displayed.

  For this reason, for example, in order to transport a lot of luggage between different floors using an elevator, the car 10 is called on the floor where the elevator user is located, and the door 10 is opened in the car 10 that has landed. When the pressing operation of the extension button 26 is performed, the elevator door 5 enters a door open extended state. As a result, the user can carry the luggage into the car 10 from the landing 30. Moreover, when it is in the door open extension state in this way, in order to display that the door open extension display part 43 is in the door open extension, use of the elevator in the landing 30 of another floor The person can recognize that the car 10 has been stopped for a long time by being in the door open extended state.

  In the door open extension state, the time set by the door open extension function elapses, or the user who has loaded the luggage into the car 10 performs the pressing operation of the door open extension button 26. And the elevator door 5 is closed. Moreover, if the door open extension state is cancelled | released, the display part 43 during door open extension will light-extinguish, and the display to the effect that the door open extension is underway will be complete | finished.

  The user who has loaded the luggage in the car 10 presses the destination button 23 to register the destination floor and move the car 10. When the car 10 reaches the destination floor, the user performs the pressing operation of the door opening extension button 26 again, so that the elevator door 5 enters the door opening extension state. Thereby, the user can carry out the luggage from the car 10 to the landing 30. In addition, even during this door open extension state, the door opening extension display unit 43 displays that the door opening extension is in progress, so that the elevator user at the landing 30 on another floor can open the door open extension state. Can be recognized.

  When it is no longer necessary to keep the elevator door 5 in an open state after the baggage has been unloaded from the car 10, the user who has transported the baggage presses the door open extension button 26 to enter the door open extended state. It cancels | releases and the opening / closing state of the elevator door 5 is returned to a normal state. The door opening extension display unit 43 turns off when the door opening extension state is released, and ends the display indicating that the door opening extension is being performed.

  In addition, when the door is extended, the guide light 16 in the car 10 is also lit, so that the user who has transported the baggage can be aware that it is in the door-open extended state. It becomes difficult to forget to cancel the extended state. In addition, since the guide light 16 can be seen from the landing 30 where the car 10 is landing, even if the user who has transported the baggage forgets to cancel the door open extension state after the transport is completed, A user at 30 gets into the car 10 and can release the door open extension state.

  Next, the flow of control when the door extension function is activated will be described. FIG. 4 is a flowchart showing a flow of operation when the elevator door open extension notifying device according to the embodiment is operated. When the elevator user performs a pressing operation on the destination button 23 or the call button 44 and the destination floor is called and registered, the elevator driving device 60 operates according to the registration information, so that the car 10 is Land on the destination floor (step ST11).

  When the car 10 reaches the destination floor, a door opening operation is performed (step ST12). That is, when the car 10 reaches the destination floor, the elevator door 5 is opened by operating the door opening / closing device 55 by the control device 50.

  When the car 10 is opened on the destination floor, it is determined whether or not the door opening extension button 26 is pressed (step ST13). For example, a user who wants to extend the door opening time for loading / unloading luggage etc. performs door opening extension by pressing the door opening extension button 26. Therefore, the control device 50 determines whether or not the door opening extension button 26 has been pressed. Determine whether.

  If it is determined by this determination that the door opening extension button 26 has not been pressed (step ST13, No determination), it is next determined whether or not the normal door opening time has elapsed (step ST14). . That is, after performing the door opening operation, the control device 50 determines whether or not the normal door opening time has elapsed when the door opening extension button 26 is not pressed and is not in the door opening extension state. . If it is determined by this determination that the normal door opening time has not elapsed (No determination at step ST14), the process returns to step ST13 to determine whether the door opening extension button 26 has been pressed.

  On the other hand, when it is determined that the door opening extension button 26 has been pressed (step ST13, Yes determination), the door opening time is extended, and the door opening extension display section 43 of the platform 30 on the entire floor is further displayed. It is lit and the guide light 16 in the car 10 is also lit (step ST15). This notifies the user at the hall 30 on all floors that the opening time of the elevator door 5 is extended, and also strongly recognizes the user in the car 10. .

  Next, it is determined whether or not the door extension button 26 has been pressed again (step ST16). That is, by determining the operation state of the door opening extension button 26, it is determined whether or not an instruction to cancel the door opening extension has been issued in the door opening extension state.

  If it is determined by this determination that the door opening extension button 26 has not been pressed (step ST16, No determination), it is next determined whether or not the door opening time during the door opening extension has passed ( Step ST17). That is, it is determined whether or not the door opening time of the elevator door 5 set by the door opening extension function has elapsed since the door opening extension button 26 was pressed. If it is determined by this determination that the door opening time at the time of door opening extension has not elapsed (step ST17, No determination), the process returns to step ST15, and the door opening extension display part 43 of the hall 30 on all floors. And the lighting of the guide light 16 in the car 10 is continued.

  On the other hand, if it is determined that the door opening time during the door opening extension has elapsed (step ST17, Yes determination), the door opening extension function is stopped to release the door opening extension, and the floor 30 The door opening extension display unit 43 and the guide light 16 in the car 10 are turned off (step ST18). Similarly, when it is determined that the door opening extension button 26 has been pressed in the door opening extension state (step ST16, Yes determination), the door opening extension is canceled and the door opening extension display section of the platform 30 on all floors is released. 43 and the guide light 16 in the car 10 are turned off (step ST18).

  As described above, when the door opening extension is canceled, the door closing operation is performed (step ST19). That is, the elevator door 5 is closed by operating the door opening / closing device 55 by the control device 50. Further, the door closing operation is similarly performed when the normal door opening time has elapsed (step ST14, Yes determination) without the door opening extension button 26 being pressed (step ST13, No determination) (step ST19).

  Since the elevator door opening extension notification device 1 described above is provided with a door opening extension display unit 43 for notifying that it is in the door opening extension state at the landing 30 on all floors where the car 10 is landing, Users on other floors can recognize why the car 10 has been stopped for a long time. As a result, it is possible to improve the recognizability of the door open extension state for the elevator user, and to reduce the stress of the user waiting on the other floor.

  Further, since the car 10 is provided with a guide light 16 for notifying the user in the car 10 that the door is in the door open extension state, the user in the car 10 can open the door open extension button 26. You can be strongly aware that is pushed and the door opening is being extended. As a result, it is possible to improve the recognizability of the door open extension state for the elevator user.

  In addition, since the user in the car 10 can recognize that the door is in the extended state as described above, the inside of the car 10 can be released when the door open extended state may be canceled. Can forget to press the door opening extension button 26 and forget to cancel the door opening extension. As a result, since the door open extension state is unnecessarily maintained and the car 10 can be prevented from continuing to stop, it is possible to prevent the driving efficiency from deteriorating while providing the door open extension function. it can.

  In addition, the guide light 16 is installed near the entrance of the car 10 and can notify the user of the landing 30 where the car 10 is landing that the door is extended, Even if it is forgotten to cancel the door opening extension, the user of this platform 30 can recognize. Thereby, when the user forgets to cancel the door opening extension, the user of the landing 30 who has recognized this can enter the car 10 and press the door opening extension button 26 to release the door opening extension. That is, even when the car 10 is unattended and in the door open extension state, a third party can cancel the door open extension. As a result, it is possible to more reliably prevent the car 10 from being unnecessarily maintained and the car 10 from continuing to stop.

[Modification]
In the elevator door opening extension notification device 1 described above, the door opening extension display unit 43 provided on the landing console panel 40 only displays text information indicating that the door opening extension is in progress. The middle display unit 43 may display other information. The door opening extension display unit 43 may display, for example, the time until the elevator door 5 that is kept open by the operation of the door opening extension function is closed. By displaying the time until the elevator door 5 is closed, it is possible to recognize the approximate time when the car 10 starts to move again, so that the user waiting at the landing 30 waits with reduced irritation. Can do.

  Moreover, in the elevator door open extension notification device 1 described above, the door open extension is canceled when a preset time elapses or the door open extension button 26 is pressed again. You may cancel on condition other than. For example, the door opening extension button 26 is mainly pressed when a large amount of luggage is taken in and out, so the load change of the car 10 is detected by a load sensor or the like, and the door opening extension is canceled based on the detected load change. May be. Specifically, when the load of the car 10 at the start of the door opening extension is a load that can be determined that there is a heavy object in the car 10, the load that can be determined that there is no transported material in the car 10. When the load on the car 10 changes, the door opening extension may be canceled.

  In other words, when the load of the car 10 changes to a load that can be determined that there is no transported goods in the car 10, the luggage or the like that was in the car 10 at the start of door opening extension is removed from the car 10. Since it can be determined that the elevator door has come out, it can be estimated that the elevator door 5 may be closed. For this reason, in this case, the door opening extension may be canceled. As a result, it is possible to prevent forgetting to cancel the door opening extension, and it is possible to more reliably prevent the car 10 from being unnecessarily maintained and the car 10 from continuing to stop.

  In addition, a function for canceling the door opening extension may be provided in the hall operating panel 40. In this case, when the state in the car 10 can be confirmed from the landing 30, it is preferable to receive a function for canceling the door extension from the landing operation panel 40.
