The operation of the embodiment of the present invention having the above-described configuration will be described next.

First, the opening/closing operation of the door when the extension operation means is not operated will be explained.

In this case, the changeover switches MS ₁ and MS ₂ provided in the control room are turned OFF.

When the elevator car arrives at the floor in response to the call, contact OS ₂ , which turns OFF when the door opens, is turned ON;
Contact OS ₁ , which is ON, is OFF.

Contact CS ₁ turns OFF when the door is closed.
remains in the OFF state.

Therefore, when the elevator car arrives at the floor, the DC power supply terminal N, contact OS ₂ , contact MA ₄ ,
The cathode side of the door-opening thyristor _SH2 is electrically connected, and the door-opening thyristor _SH2 becomes conductive, so that the door motor M rotates in the direction of opening the elevator door, and the elevator door is opened.

Then, when the elevator door is fully open, contact OS ₂ turns OFF and contact OS ₁ turns OFF.
Since it is turned ON, a closed circuit is formed by the DC power supply terminal P, the contact OS ₁ , the contact B ₂ , the door closing command timer TA, and the DC power supply terminal N, and the door closing command timer TA starts counting.

When this door closing command timer TA counts, for example, 5 seconds, contact TA ₁ turns ON, so DC power terminal P, door safety device contact SS, door open button OB, contact
A closed circuit is formed by A ₁ , contact TA ₁ , opening/closing auxiliary relay MA, and DC power supply terminal N, and the opening/closing auxiliary relay
MA is activated.

When opening/closing auxiliary relay MA is energized, the contacts
MA ₁ turns ON and opening/closing auxiliary relay MA is self-held.

In addition, due to the energization of opening/closing auxiliary relay MA, contact MA ₃ turns ON, contact MA ₄ turns OFF,
If door closing is not completed, contact CS ₁ is in the ON state, so the voltage at DC power supply terminal P is the same as door closing thyristor SH _1.
is applied to the cathode side of the door closing thyristor _SH1 , so that the door motor M rotates in the direction of closing the elevator door, and the elevator door is closed.

In this way, after the elevator door is fully opened, the door will automatically close again after the 5-second opening time has elapsed, so that the elevator car will be closed again automatically after 5 seconds have elapsed since the elevator door is fully opened. The elevator will start operating immediately and the elevator will operate efficiently.

In addition, even if the door opening extension button OBA is operated in this case, since the changeover switch MS ₁ is OFF, the opening time extension auxiliary relay A will not be energized, and the door opening time extension operation will not be performed. Not possible.

For this reason, mischief by children or erroneous operations by passengers can extend the door opening time, reducing elevator operation efficiency and causing irritation to passengers waiting on other floors. do not have.

Next, if a passenger wants to put a bed or luggage into the elevator car, he/she will notify the manager and the manager will turn on the switches MS ₁ and MS ₂ located in the control room. do.

In this way, selector switches MS ₁ and MS ₂ are turned on.
Then, DC power supply terminal P, selector switch _MS2 ,
A closed circuit is formed by the extension indicator lamp _L1 and the DC power supply terminal N, and the extension indicator lamp is lit.

At the same time, DC power supply terminal P, door opening extension button OBA,
Since a closed circuit is formed by the changeover switch MS ₁ , the opening time extension auxiliary relay A, and the DC power supply terminal N, the opening time extension auxiliary relay A is energized.

When this opening time extension auxiliary relay A is energized, contact A ₁ turns OFF and contact A ₂ turns ON, so the opening/closing auxiliary relay MA cannot be energized except by operating the door close button CB, and the opening time Extension relay B
is energized.

When the opening time extension relay B is energized in this way, the contact B ₁ turns ON, so a closed circuit is established between the DC power terminal P, the contact MA ₂ , the contact B ₁ , the extension command timer TB, and the DC power terminal N. is formed, and the extension command timer TB starts counting.

At the same time, DC power supply terminal P, contact A ₂ , contact TB ₁ ,
Closed time extension indicator lamp _L2 and DC power terminal N form a closed circuit, so the closing time extension indicator lamp L2 and DC power terminal N form a closed circuit.
L ₂ lights up.

Then, when the extension command timer TB counts a predetermined time, for example 3 minutes, contact TB ₁ turns OFF and contact TB ₂ turns ON, so the open time extension indicator lamp
L ₂ goes out and floor time extension completion buzzer BZ operates.

In addition, when contact TB ₂ turns ON, the extension completion door closing command timer TC starts counting, and after a predetermined time, contact TC ₁ turns ON, and the opening/closing auxiliary relay is activated.
MA is activated.

When the opening/closing auxiliary relay MA is energized in this way, the contact MA ₃ is turned ON as described above, so the door closing thyristor SH ₁ becomes conductive, and the door motor M moves in the direction to close the elevator door. As it rotates, the elevator door closes.

Therefore, a passenger who intends to transport a bed or luggage in a passenger car should confirm that the extension indicator lamp L ₁ is lit, operate the door opening extension button OBA, and then press the door opening extension indicator lamp L ₂ . Beds and luggage can be safely loaded into the car within the extended door opening time until the lights are turned off and the opening time extension completion buzzer BZ is activated.

When the extended door opening time is completed, the opening time extension completion buzzer BZ is activated, the opening time extension indicator lamp _L2 is turned off, the door is closed, and the elevator starts operating to the target floor.

Even after arriving at the desired floor, you can operate the door opening extension button OBA in exactly the same way and safely remove your bed and luggage from the car during the extended door opening time.

In this way, when a customer uses an elevator to transport a bed or luggage, the elevator operation mode can be switched to extended door opening time mode by notifying the manager. By operating the opening extension button OBA, you can set the opening time required for loading and unloading the bed and luggage.

In addition, the door opening extension button OBA cannot be operated in the control room unless requested by the customer.
The door opening time will not be extended unnecessarily due to mischief or erroneous operation, which will not reduce the efficiency of elevator operation or cause users on other floors to wait longer and feel irritated. .

[Effect of idea]

As explained in detail above, according to the present invention, the extension operation means is effective only when it is necessary to extend the door opening time. This prevents the elevator operating efficiency from decreasing due to the extension of time, and from causing a sense of irritation to passengers on other floors.
