Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator door extension device for extending the opening time of an elevator door.

[Conventional technology]

The elevator is equipped with a door closing means, and when the car arrives at the destination floor and the door is fully opened, the door closing means is activated and the door closing operation is performed after a predetermined time, for example, 3 seconds after the door is closed. However, because there are many people using the elevator, it may take time to get on and off the elevator, and when the elevator is used to transport luggage, it may take time to load and unload it.

Therefore, normal elevators are equipped with a door opening extension button on the operation panel, and when this extension button is operated, a predetermined extension time,
For example, the door opening time is extended by 3 minutes. If a door opening extension button is provided separately in this way, some users may misuse the door opening extension button even though it is not actually necessary, which increases elevator downtime and reduces operational efficiency. This poses a problem of causing inconvenience to other customers.

On the other hand, in Japanese Utility Model Application Publication No. 1-72570, when the elevator is in a stopped state and the door is fully opened, by operating the opening button provided on the operation panel, the door opening time is set to a predetermined time, for example, 3. An elevator door opening extension device is disclosed that extends the opening for minutes.

[Problem to be solved by the invention]

In the elevator door opening extension device according to the disclosure, it is necessary to operate the opening lever during the three seconds from when the door fully opens until it begins to close. It can be quite difficult to operate. During the second half of the three-second door opening time, the bank is often crowded with customers rushing to get on or get off the cage, so it is often difficult to operate the bank.

In addition, even if an elevator user who is not a user who is trying to use this elevator door opening extension device to carry luggage, etc. operates the opening bank in front of a passenger who is in a hurry to get on the car, the elevator door will open. For example, the door remains open for three minutes, and the door is opened against the customer's wishes.

The present invention has been made in order to solve the problems with the elevator door opening extension device disclosed in the prior art as described above, and its purpose is to avoid abuse when unnecessary and to facilitate operation when necessary. To provide an elevator door opening extension device that prevents the door from opening against the will of a customer.

[Means to solve the problem]

The object is to provide a door closing means for closing the door after a first predetermined period of time has elapsed after the boarding/exiting door of the elevator is fully opened, and a door opening means for opening the door when the door is operated in the closed state. and a door opening time that is activated by operating the door opening means during the door opening operation when the car is stopped, and extends the opening time of the door to a second predetermined time. This is achieved by providing extension means.

[Effect]

With this configuration, a passenger who wishes to extend the door opening time can use the door opening means to open the door to another passenger while the elevator is opening the door after the car has stopped and no passengers have moved yet. Operate smoothly without any interference. This operation activates the door-opening time extension means, and the door-opening time is extended, for example, by three minutes.

In this case, since the emergency door is not opened while the elevator door is opening, the opening time will not be extended against the will of other passengers, and abuse of the door will not be extended. Appropriate door opening times will be extended.

Next, the operation of the embodiment will be explained.

First, the normal opening/closing operation of the door will be explained.

Assuming that a customer gets on the elevator on the first floor, the customer operates a landing call operation for the first floor, and the car is called to the first floor and stopped there.

When the elevator stops, contact 10b2 turns ON, and when the car detects the 1st floor door open zone, contact FCa turns on.
becomes ON. At this time, since the door opening command is not issued, contact 101b2 is ON, and contact 0LSb 1
is ON.

Therefore, the DC power supply terminal P, contact 10b2, contact FCa
, contact 101b2, contact ○LSbl, relay 102, and DC power supply terminal N form a closed circuit, and since relay 102 is energized, a door opening command is issued and the elevator door opens.

When a passenger gets into the car and operates, for example, car call button 3B on the third floor of driving panel B, contacts 10b11. tO
N, contacts 101bl and 102bl are also ON, auxiliary relay 20 is deenergized and contact 20b is ON, so DC power terminal P, contact 10b1, contact 101bl, contact 1o
2b1, contact 2゜b, timer T1 and DC power supply terminal N
A closed circuit is formed at , and timer T1 starts timing.

When the first predetermined time of 3 seconds has elapsed, the timer T1 completes timing, and the contact Tla is turned ON. At this time, the open chain BO is not operated and the contact Bob is ON, and since the gear is not engaged during deceleration, the contact 92b is ON.

Therefore, when the contact Tla turns ON, the DC power terminal P,
A closed circuit is formed by contact T1a, contact Bob, contact 92b, auxiliary relay 100, and DC power supply terminal N, and auxiliary relay 100 is energized and self-held by contact 100al.

When the auxiliary relay 100 is energized, the contact 100a2 turns ON.
At this time, contact 102b2 and contact CLSbl are O.
N, a closed circuit is formed by the DC power terminal P, the contact 100a2, the contact 102b2, the contact CLSb1, the relay 101, and the DC power terminal N, and the relay 101 is energized. Therefore, a door close command is issued and the door is closed.
When the door is completely closed, the contact CLSb1 is turned off and the relay 101 is deenergized. After that, the elevator is operated by a control device (not shown), and the car travels toward the third floor.

When the car approaches the third floor, the speed is reduced, so contact 92b turns OFF.
F, the auxiliary relay 100 is deenergized, and when the car stops on the third floor, the same operation as described above is performed when the car stops on l111.

Next, the operation of the silver opening BO when the door is closed and the operation of the opening silver BC when the door is open will be explained.

For example, when the door starts to close, if a passenger tries to get into the car and a passenger in the car operates the Kaigin BO,
Since the contact Bob is turned OFF and the auxiliary relay 100 is deenergized, the contact 100a2 is turned OFF. By turning off the contact 100a2, the relay 101 is deenergized and the contact 101b2 is turned on. At this time, the elevator is stopped and contact 10b2 is ON, the car is detecting the door open zone of the floor in question, contact FCa is ON, and contact 0LSb1 is ON, so relay 102 is activated. The door is energized and opened.

In addition, when the bank opening BC is operated in the car after the passenger has boarded and alighted, the contact BCa turns ON, and at this time, the contact B Ob
! , tON, contact 92b is also ON, so auxiliary relay 10
0 is energized and the contact 100a2 is turned on. Contact 100
When a2 turns ON, at this time contact 102b2 and contact CL
Since Sb 1 is ON, relay 101 is energized and the door is closed.

Finally, the operation of operating the opening BO when the stopped iron door is starting to open to extend the opening time to the second predetermined time will be explained.

When the opening silver BO is operated, the contact Boa turns ON, and at this time the car is stopped and the contact 10b1 is ON, the door is starting to open and the contact 10bl is ON, the door is starting to open and the contact 40b is ON, and the door has reached the opening end. Since there is no contact point 0
Since LSb2 is ON, DC power supply terminal P, contact 10
A closed circuit is formed by BL, contact BOa, contact 40b, contact 0LSb2, auxiliary relay 20, and DC power supply terminal N, and auxiliary relay 20 is energized and self-held by contact 20a1. When the auxiliary relay 2o is energized, the contact 20a2
is turned ON, and the contact 20b is turned OFF.

At this time, contact 10b1 is ON, contact 101bl is ON,
Since contact 102bl is ON, DC power supply terminal P, contact 10bl, contact 101bl, contact 102bl
, contact 20a2, timer T2, and DC power supply terminal N form a closed circuit, and timer T2 starts timing.

Therefore, when the second predetermined time of three minutes has elapsed, the timer T2 completes timing and the contact T2a turns ON. At this time, contact Bob is ON and contact 92b is ON, so when contact T2a is turned ON, auxiliary relay 100
is energized and self-held by contact 1°Oal.

In this way, when the auxiliary relay 100 is energized, the relay 101 is de-energized and the relay 102 is energized, and the door closes after 3 minutes of opening time, extending the opening time. The door is then closed. Therefore, by operating the opening BO when the door is starting to open, the customer can extend the opening time and perform tasks such as loading and unloading luggage. In this case, the extended door opening time will be 3
When the work is completed within minutes, the door can be closed immediately by operating the opening Bc as described above.

Moreover, since the contact 0LSb2 is turned OFF when the door is fully opened, the auxiliary relay 2o is not energized even if the opening silver BO is operated after that, and the door opening extension operation is not performed.

In this manner, according to the embodiment, if the opening silver BO is operated while the door is starting to open, the door opening time is extended to the second predetermined time, so that the door opening time is not extended unnecessarily. The opening bank BO operation when extending the door opening time is performed when no customers have moved yet, so it can be performed smoothly without being blocked by the moving customers. In addition, since the door opening time is not extended in the normal operation of the Open Bank BO in an emergency, the door opening time will not be extended against the customer's will.

〔Effect of the invention〕

As explained in detail above, the present invention extends the door opening time to the second predetermined time when the door opening means is operated during the door opening operation, so that the door opening time extension operation may be abused when unnecessary. The door opening time can be extended appropriately according to the customer's wishes without being accidentally opened or operated incorrectly.
