Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator door opening/closing device, and more particularly to an elevator door opening/closing device in which the door is opened and closed by a common operation button.

[Conventional technology 1] In a conventional elevator door opening/closing device, a door opening/closing button and a door closing button are arranged close to each other on the operating panel inside the car, and either button is selected and operated according to the passenger's boarding/alighting status. By doing so, the door can be opened and closed in addition to the predetermined door opening and closing operations. However, because the ``Open'' display for door opening and the ``Closed'' display for door closing are similar in appearance, they are relatively often operated incorrectly during emergency operations. Clothes were sometimes sandwiched between the car door and the landing door.

In order to prevent such accidents from occurring,
In Publication No. 267687, if the door open/close or the door close is operated during the door closing operation, a door opening command is issued and the door is reversed and restarted, and when the door opening/closing or door closing is operated during the door opening operation, a door closing command is issued. A door opening/closing device is disclosed in which the door is reversed and reclosed. In the door opening/closing device according to this disclosure, when the door is reversed and reopened, the door closed display switches from a "close" display to an "open" display, and when the door is reversed and reopened, the door open/close display is switched to "open". The display changes from "Open" to "Closed".

[Problem to be Solved by the Invention 1] In the door opening/closing device according to the above disclosure, when the elevator door is fully open, the display of the two operation buttons is "
The display will be different from the "open" and "close" displays, so if the door is fully open and a passenger is getting on or off, if you accidentally press the "close" button, a door close command will be issued and the door will close. It was dangerous for the door to hit the closed customers.

The present invention was made in view of the current state of elevator door opening/closing devices as described above, and its purpose is to prevent passengers from being exposed to danger due to the opening/closing of doors due to erroneous operation of the operation button while the passenger is getting on or off the elevator. The purpose of the present invention is to provide an elevator door opening/closing device that is not as good as the conventional one.

[Means to solve the problem]

In order to achieve the above object, an elevator door opening/closing device that opens and closes the elevator door by operating an operation button provided on a driving panel in the elevator car,
an operation button that is operated in common when opening and closing the door; and an operation button that is activated by the operation of the operation button, and opens the door when the door is fully closed or when the door is closed; Sometimes, the door opening/closing means for closing the door is provided.

[Function] With this structure, when the operation button that is commonly operated when opening and closing the door is operated when the door is fully closed or closed, the door opens, and when the door is fully opened, the button is operated when the door is fully opened. Then the door closes.

Therefore, the operation button is not operated erroneously, and the elevator door is opened and closed without posing a danger to the passengers due to the opening and closing of the door.

A closed circuit is formed by the door open command relay 9 and the DC power supply terminal N, and the door open command relay 9 is energized to issue a door open command.

This door opening command causes the elevator door to open, and the normally open contact 9a turns ON, and the DC power terminal P, normally closed contact 3, normally open contact 9a, door open indicator 2B, and DC power terminal N are connected. A closed circuit is formed and the door open indicator light 2B lights up.

In addition, if the operation button 2 is operated during the door closing operation, the normally open contact 4al is turned on, and at this time, the door closing operation detection relay is energized and the normally open contact 6a is turned on, so the direct current A closed circuit is formed by the power terminal P, the normally closed contact 3, the normally open contact 6a, the normally open contact 4al, the door open command relay 9, and the DC power terminal N. Therefore, the door opening command relay 9 is energized to perform the door opening operation, and at the same time, the door opening indicator light 2B is lit.

The door opening operation is performed in this way, and when the door is fully open, the fully open detection relay is energized and the normally open contact 7al is turned ON.
becomes. Therefore, a closed circuit is formed by the DC power supply terminal P, normally closed contact 3, normally open contact 7al, @closed contact 5b, timer T, and DC power supply terminal N, and after timer T has counted a predetermined count, normally open contact TI is closed. It is turned ON and timer T is self-maintained. In addition, since the normally open contact T2 is also turned ON, a closed circuit is formed by the DC power supply terminal P, the normally closed contact 3, the normally open contact T2, the door close command relay IO, and the DC power supply terminal N, and the door close command relay 10 is activated. energize.

When the door close command relay 10 is energized, a door close command is issued, the elevator door is closed, and the normally open contact 10a is turned on, so that the DC power terminal P1 normally closed point 3 and the normally open contact 10a, a closed circuit is formed by the door closed indicator light 2C and the DC power supply terminal N, and the door open indicator light 2C lights up.

Next, when the passenger presses the operation button 2 with the door fully open, the fully open detection relay is energized and the normally open contact 7a2
