DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for displaying when an elevator closes a door to depart from a landing.

[0002]

2. Description of the Related Art In an elevator, a car door and a landing door (hereinafter simply referred to as a door) are closed when a car stopped at a landing departs to respond to a next call. It has been proposed to display that the door will be closed in order to inform the waiting passengers at the landing of this condition. For example, JP-A-1993-1
The abstract of No. 7090 discloses that a door closing display device is incorporated in a landing button, and that the display blinks when the door closing operation is started.

[0003]

In the above-described conventional elevator door-closing display device, since the display device is incorporated in the landing button, the size of the landing button becomes large, and the existing landing button is replaced with the new landing button. When replacing with a button, installation becomes impossible. In addition, it is necessary to add a device and a wiring for display, which is disadvantageous in terms of construction, maintenance, and cost.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide an elevator door-close display device which can display a door-close operation without requiring a dedicated display device. And

[0005]

According to a first aspect of the present invention, when a car arrives at a landing and opens the door, an elevator door registration light incorporated in the landing button is turned on. The hall call registration lamp blinks prior to the door closing operation.

The elevator door-closing display device according to the second invention is the elevator door-closing display device according to the first invention, wherein when the car arrives at the landing and opens the door, a landing call built in each direction-specific landing button. The hall call registration light in the same direction as the direction of operation of the car of the registration light is turned on, and the lit hall call registration light blinks prior to the door closing operation.

In the elevator door closing display device according to the third invention, when the car arrives at the landing and opens the door, the door opening button light incorporated in the door opening button in the car is turned on to close the door. Prior to the operation, the door opening button light flashes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 1 and 2 show an embodiment of the first to third inventions of the present invention. FIG. 1 is an overall configuration diagram, and FIG. 2 is an operation flowchart. In FIG. 1, 1 is a control panel or group control panel, 1a and 1b are display command signals output from the control panel or group control panel 1, and 2 is a hall that receives a display command signal 1a and outputs a display command signal 2a. A button display I / F (interface) 3 is a hall button for inputting a display command signal 2a. When a hall call is registered (detailed description is omitted), a hall call registration light 4 for displaying the direction is built in. are doing.

Reference numeral 5 denotes an I / F for a car device which receives the display command signal 1b and outputs the display command signal 2b, and 6 denotes an in-car operation panel which receives the display command signal 2b and outputs a door opening command. The door opening button light 7 is built in the door opening button. 8 controls the opening / closing of the car door and provides door opening / closing information 8a.
Is a car door opening / closing control device which outputs the door opening / closing information 5a to the control panel or the group management panel 1.

Next, the operation of this embodiment will be described with reference to FIG. In step S1, the elevator car arrives at the landing and opens the door. (At this time, the hall call registration lamp 4 of the hall button 3 is turned off.) In step S2, the hall call registration lamp 4 is turned on by the display command signals 1a and 2a, and the car operation panel 6 is turned on by the display command signals 1b and 2b. The door opening button lights 7 are respectively turned on. When a predetermined time elapses after the door is fully opened, a door closing operation start notice is detected in step S3.

Then, in step S4, the display command signal 1
a, 2a, the hall call registration light 4 is turned on and the display command signal 1 is turned on.
The display mode of the door opening button light 7 is changed from lighting to blinking by b and 2b, and a person who is going to get on the car and a person who is getting on are warned that the door starts to close. In addition, the hall call registration light 4 when the door is open only turns on or blinks in the same direction as the direction of travel of the car, but turns on or flashes the hall call registration light 4 in both directions depending on the use condition of the elevator. It is also possible to highlight and display the start of the closing operation.

The predetermined time described in step S3,
That is, the time limit for the door closing operation start notice may be set to an arbitrary time period depending on the use status of the elevator. Now,
After the time limit for detecting the notice of the start of the door closing operation, the door closing operation is started in step S5, and the door closing operation is completed in step S6. Then, in step S7, the hall call registration light 4 and the door open button light 7 stop blinking and are turned off.

The door opening / closing information 8a indicating the door opening / closing state.
The door opening / closing information 5a output from the basket door opening / closing control device 8
Is input to the control panel or group control panel 1 and the display command signal 1
a and 1b are output. Here, steps S1 and S2 constitute a door open state display means, and steps S3 and S4 constitute a door closing operation start display means.

In this way, the notice of the start of the door closing operation and the state during the door closing operation are indicated by the flashing of the hall call registration light 4 and the door open button light 7, thereby increasing the size of those devices. In addition to this, it is possible to easily inform the user of the inappropriate timing of getting on and off, and to guide the user to operate the door re-opening during the door closing operation without error. In addition, at the hall where the car is stopped, the hall call registration light 4 is normally turned off, but when only the hall call registration light 4 in the same direction as the car travels is turned on or blinks, the car operation direction is changed. However, it becomes easier to discriminate, and it is possible to prevent an erroneous ride or an erroneous operation when the door is opened again.

[0015]

As described above, according to the first aspect of the present invention, when the car arrives at the landing and opens the door, the landing call registration light is turned on, and the landing call registration light blinks prior to the door closing operation. So, without having to increase the size of the equipment, while notifying in advance the unsuitable time of the ride easily,
The user can be guided to operate the door re-opening during the door closing operation without error.

Further, in the second invention, the hall call registration lamp for each direction is turned on in the same direction as the direction of travel of the car, and the lit hall call registration lamp is flickered prior to the door closing operation. Therefore, the operation direction of the car can be more easily distinguished, and erroneous operation at the time of erroneous boarding and re-opening of the door can be prevented.

Further, in the third invention, when the car arrives at the landing and opens the door, the door opening button light is turned on and the door opening button light blinks prior to the door closing operation. Without increasing the size, it is possible to give an easy-to-understand notice of the inappropriate time for getting off, and to guide the user to operate the door re-opening during the door closing operation without error.
