Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator door control device.

[0002]

2. Description of the Related Art Generally, an elevator door is controlled so as to be closed a predetermined time after the door is opened. However, there is an inconvenience that the transport of a large luggage or a bicycle is not completed, and the transported product is sandwiched between doors to damage both.

As a prior art for solving this inconvenience, there is a door control device disclosed in Japanese Patent Laid-Open No. 5-97363.

This door control device is provided in a trunk portion of a car, and when a detection switch for detecting that a bicycle has been carried is operated, if a bicycle user arrives at a destination floor, the door opening time is extended. Control.

[0005]

However, the above-mentioned prior art is effective when getting off the car, but does not take into account when getting into the car, and prevents the load from being caught in the door. There was an inconvenience of not being able to do so.

The present invention has been made in view of the above-mentioned inconvenience, and an object of the present invention is to provide an elevator door capable of preventing the large-sized luggage or bicycle from being caught in the door even when being carried into a car during transportation. Related to a control device.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to an elevator door control device for controlling the opening and closing of a car door provided with a trunk portion having a door which can be opened and closed on a side surface. In addition to providing a dedicated call button,
Detecting means for detecting the opening of the door of the trunk unit are provided, and when the exclusive call button is pressed and the detecting means is operated, a command to close the door is issued.

According to the present invention, since the elevator door control device is configured to issue a door closing command when the dedicated call button provided at the landing is pressed and the door of the trunk is detected to be open, If the luggage is not put in the trunk, the door does not close and the luggage can be safely carried in.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of an inside of a car showing an operation state of a door opening detecting means of a trunk portion, FIG. 2 is an electric circuit diagram of an elevator door control device of the present invention, and FIG. It is a landing front view which shows an installation position.

As shown in FIGS. 1 and 3, the elevator car 17 to which the embodiment is applied has a large luggage or a bicycle 15 on a rear side wall 17a in the car 17 facing the car door 16. To facilitate insertion, a hinge 14b is provided so that the trunk door 14a can be freely opened and closed, and a detection switch 4 that is turned ON when the bicycle 15 is inserted to open the trunk 14a is provided. When carrying the bicycle 15, a dedicated call button 1B is provided below the hall operation panel 18. After the call is registered on the exclusive call button 1B, when the car arrives at the registered floor, the door control device of the present invention links the hall door 19 with the car door 16 and opens the door. After the door is opened, the control method is such that a door-close command is not issued until the detection switch 4 is turned on and operated.

An electric circuit for performing the control for not issuing the door closing command is configured as shown in FIG. 2, and a normally closed contact 2b of the dedicated call button relay 2 between the DC power terminals P and N.
And the normally open contact 4a of the detection switch 4 are connected in series, and the close button switch 6 and the normally open contact T1 of the door close command timer T are connected in parallel, and the door close command preparation relay 3 is connected in series. I have. A series connection circuit of a normally open contact 5 of a door open completion confirmation relay (not shown) and a door close command timer T, and a normally open contact 2a of a dedicated call button switch 1 and a dedicated call button relay 2 in parallel with a door close command. A series connection circuit of the normally closed contact 3b of the preparation relay 3 and the dedicated call button relay 2 and a series connection circuit of the normally open contact 3a of the door closing command preparation relay 3 and the door closing command circuit 7 The power supply terminals P and N are connected in series.

Next, the operation of the door control device of the present invention will be described.

When the dedicated call button switch 1B is pressed, the dedicated call button relay 2 is energized. When the dedicated call button relay 2 is energized, the normally open contact 2a of the dedicated call button relay 2 is closed, a circuit of P-2a-3b-2-N is formed, and the dedicated call is registered. You.

Next, a description will be given of a process from when the car arrives at the call registration floor until a door closing command is issued. After arrival, the landing door 19 and the car door 16 are opened in conjunction with each other, the door is fully opened, the normally open contact 5 of the relay for confirming completion of door opening (not shown) is closed, and the door closing command timer T is energized to count the timer. Start. Next, when the counting is completed, the normally open contact T1 of the door closing command timer T is closed, and the circuit P-2b of the relay 3 for preparing a door closing command is closed.
-4a-T1-3-N is formed, and the door closing command preparation relay 3 is energized. As a result, the normally open contact 3a of the relay 3 for preparing the door closing command is closed, and the door closing command circuit P-3a-
The door is closed by the formation of 7-N.

According to the present invention, the elevator door control device is configured to issue a door closing command when the dedicated call button 1B provided at the landing is pressed and the door of the trunk portion 14 is detected. Therefore, the door does not close unless luggage is put in the trunk 14, and the luggage can be safely carried in.

[0017]

As described above, according to the present invention, since the control device for the elevator door is constructed, it is possible to prevent the large door or the bicycle from being caught in the door when carrying a large load or bicycle. .
