Description

[Detailed Description of the Invention] This invention relates to an elevator door device.

Elevator entrances and exits are generally equipped with electric doors. Such door devices open and close under automatic control, and are installed on the walls of the entrance and exit edges of elevator cars by passengers only when necessary. There are some types of doors that have an opening/closing button operated by the driver, and others in which the driver operates the opening/closing button to open and close the door. Such a door device is convenient because it saves passengers time, but if the elevator is installed in a residence and is mainly used for personal use, it is necessary to manually open and close the sliding door inside the residence. There is a problem with the electric door that makes it feel strange and confusing to operate.

This invention aims to eliminate the above-mentioned drawbacks and provides an elevator door device that can be operated by an operation equivalent to that of a manual sliding door.

An embodiment of this invention will be described below with reference to FIGS. 1 to 3.

In the figure, 1 is the elevator landing, 2 is the entrance/exit of this, 3 is the elevator car that lands and stops at the landing 1, 4 is the entrance/exit of this, 5 is the sliding door that opens and closes the entrance/exit 2, and 5a is the sliding door. A surface of a protrusion protruding from the edge of the doorway 2 when fully opened, 5'
is similar to the sliding door 5 and is provided at the entrance 4 and has a surface 5a'; 6 is a recess provided on the surfaces 5a and 5a' of the protrusion, respectively; 7 is built into the sliding door 5 and 5'. 7a is a stand for the door closing operation tool, and 7b is a door closing operation tool placed at the end of the door stop on the side of the recess 6, and 7b has an intermediate portion pivotally attached to the stand 7a, and one end extending from the side wall of the recess 6. It is arranged so as to protrude, and the other end is a stand 7a.
The operating piece 7c is a lever that is prevented from rotating clockwise in FIG.
A spring is provided between a and the actuating piece 7b to urge the actuating piece 7b clockwise, and 7d is a switch that is built in the sliding door 5, 5' and operates when the actuating piece 7b is displaced counterclockwise. 7e is this normally open contact,
Reference numeral 8 denotes a door opening operating tool similar to the door closing operating tool 7, which is placed on the side of the door bag on the side of the recess 6, and includes a base 8a, an operating piece 8b consisting of a lever, a spring 8c, and a switch 8.
d. It is constructed in the same way as the door closing operating tool 7 with a normally open contact 8e. 9 is a normally closed contact of a stop detection relay that is deenergized when car 3 stops at landing 1;
0 is the door close controller, 11 is the door open controller, 12 is the normally closed contact of the switch that operates when the sliding doors 5, 5' are fully closed, and 13 is the normally closed contact of the switch that operates when the sliding doors 5, 5' are fully open. Normally closed contact, 14 is sliding door 5,
5' drive device, 15 door closing/door opening controller 10;
A control device consisting of 11, + and - are power supplies.

That is, when the sliding doors 5, 5' are fully opened, the recesses 6 provided in the protrusion surfaces 5a, 5a' are closed.
Door opening operating tools 7 and 8 are attached. Now, if the car 3 is stopped at the landing 1 and the sliding doors 5 and 5' are fully open, the contacts 9 and 12 are closed, and the contact 13 is open. In this state, when the actuating piece 7b for closing the door is pressed, that is, operated in the door closing direction, the contact 7e is closed (+) -9-7e
The driving device 14 is energized via the door closing controller 10 by the circuit -10-12-14-(-).
As the operating piece 7b continues to be pressed, the sliding doors 5, 5' open and reach the fully closed position, the contact 12 opens and the drive device 14 is deenergized. Also, during the closing operation of the sliding doors 5, 5', the actuating piece 7b
When the pressure is released, the contact point 7e opens and the drive device 14 is deenergized, so that the sliding doors 5, 5' stop. In this state, the contact 13 is closed, and when the operating piece 8b is pressed, that is, operated in the door closing direction, the contact 8e is closed (+)-8e-11-13-
The driving device 14 is energized by the circuit 14-(-) via the door opening controller 11, and the sliding doors 5, 5' are reversed and opened. In addition, when opening the fully closed sliding doors 5, 5', the circuit shown in FIG. 3 is activated by operating the door opening operating piece 8b.
Although a detailed explanation will be omitted, an effect similar to that obtained when the sliding doors 5, 5' are fully opened and then closed is obtained.

In this way, when opening and closing the sliding doors 5, 5', the purpose can be achieved by operating the elevator passenger at a position opposite the sliding doors 5, 5' in the same manner as when opening and closing a manual sliding door, It can be opened and closed safely and easily without any confusion.

In this embodiment, even if only the door opening operating tool 8 is provided and the door closing operating tool 7 is omitted, when the sliding doors 5, 5' are opened, the first
- Almost the same effect as the embodiment shown in FIG. 3 can be obtained.
In addition, in the embodiments shown in FIGS. 1 to 3, when the door closing/opening operation tools 7, 8 are released from being pressed while the sliding doors 5, 5' are in operation, the sliding doors 5, 5' are immediately reversed. It is also possible to configure the electric circuit so that the reversal operation is performed after reaching the end of operation.

Further, even if the door closing/opening operating tools 7 and 8 in the embodiments of FIGS. 1 to 3 are constructed of pressure-sensitive tape switches, pressure conductive rubber, proximity switches, etc., the same effect can be obtained. It is clear that this can be obtained.

As explained above, this invention provides a sliding door whose end on the door stop side protrudes from the edge of the door bag side towards the center of the doorway when the doorway is opened, and a sliding door that is operated on the surface of the protruding part of the sliding door. An actuating piece that is displaced at certain times is arranged, and the displacement of this actuating piece operates the switch, and the sliding door is driven in the same direction as the direction of displacement of the actuating piece. This allows elevator passengers to operate the elevator door system in the same way as opening and closing a manual sliding door from a position opposite the sliding door, allowing them to safely and easily open and close the sliding door without any confusion. It is something that will be realized.
