Description

[Detailed Description of the Invention] This invention relates to an improvement of a communication device that communicates between the inside and outside of an elevator car.

2. Description of the Related Art It is well known that elevators are operated by operating a hall button provided in a hall and a car button provided in a car.

However, in hospitals, rehabilitation facilities for the physically disabled, etc., disabled people who use wheelchairs (hereinafter referred to as "disabled persons") often share elevators with the general public.

In this case, the landing button and the car button are located too high for a disabled person using a wheelchair, making them difficult to operate.

Therefore, in order to accommodate the convenience of these disabled people, hall buttons and car buttons exclusively for the disabled have been provided at lower positions than the hall buttons and car buttons operated by the general public.

Figure 1 shows that a general boarding button 2 is provided on the side of the boarding entrance 1, and below that, boarding buttons 3 and 4 for the disabled are provided in positions that can be operated while in a wheelchair. show.

In addition, in FIG. 2, a car operation panel 8 for the general public is provided on the sleeve wall 7 on the side of the entrance 6 of the car 5.
A car operation panel 10 for the handicapped and a communication device 11 are shown on the side wall 9 at a position lower than the car operation panel 8 for the general public and at a position that can be operated while in a wheelchair.

The communication device 11 is provided with a communication switch 12 operated by a passenger and an automatic communication light 13.

Now, when a passenger is trapped in the elevator car 5 for some reason (for example, when a safety device is activated and an emergency stop occurs), the passenger operates the telephone switch 12 to contact the control room. Wait for rescue.

However, if a disabled person is riding in the car 5, it is difficult to quickly operate the call switch 12 in an emergency. As a result, communication with the outside world is delayed, causing anxiety for the disabled.

This invention is intended to improve the above-mentioned drawbacks, and aims to provide a telephone communication device for an elevator that allows a person with a disability to automatically make a telephone conversation without requiring the user to operate a telephone switch.

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

In Fig. 3, 14 is a speaker installed in the car 5, 15 is a microphone, 16 is a control room,
17 is a speaker installed in the control room 16, 18 is a microphone, 19 and 20 are amplifiers, and 21
~23 is a DC power supply, 24 is an emergency bell, 25 is an emergency bell switch, 26 is a telephone relay, and 26a
26c is a normally open contact, 27 is a handicapped call relay contact that is closed when a handicapped car call or a landing call is registered by the handicapped car operation panel 8 and landing buttons 3, 4, and 28 is a handicapped handicap call relay contact. Dedicated operation relays are normally open contacts 28a to 28c, and 29 is an operation light exclusively for disabled persons provided in the control room or the landing.

In an emergency, when a passenger in the car 5 closes the call switch 12, the call relay 26 is activated by the DC power supply 23.
is energized and the contacts 26a to 26c are closed. Assuming that the emergency bell switch 25 is closed,
Emergency bell 24 rings.

When the manager hears the sound of the emergency bell 24, he opens the switch 25 to stop the emergency bell 24. When a passenger in the car 5 speaks into the microphone 15, the voice is transmitted to the contacts 26a and 26b and the amplifier 2.
0 and is emitted from speaker 17 to management room 16.

When the administrator speaks into the microphone 18, this voice is output from the speaker 14 via the amplifier 19.

After completing all emergency procedures, switch 1
2 is opened and switch 25 is closed.

When the switch 12 is opened, the communication relay 26 is deenergized, the contacts 26a to 26c are opened, and the normal state is restored.

When the handicapped-only call is registered, the handicapped-only call relay contact 27 is closed. As a result, the handicapped person driving relay 28 is energized, and the contacts 28a~
28c is closed. At the same time, a driving light 29 for disabled people in the control room or landing area and an automatic call light 13 in the car
lights up.

In this case, since the switch 12 is not closed, the communication relay 26 is not energized and its contact 2
Since 6c is open, the emergency bell 24 will not ring.

When a passenger in the car 5 speaks into the microphone 15, the voice is transmitted from the speaker 17 to the control room 16 via the contacts 28a, 28b and the amplifier 20. When the car 5 reaches the destination floor, the handicapped person call relay contact 27 opens. As a result, the disabled driving relay 28 is deenergized, and the contact 2
8a to 28c are open. At the same time, the disabled driving light 29 and the automatic call light 13 are turned off.

In addition, although the above-mentioned embodiment explained the case where an automatic call is made when a call for the disabled occurs, the present invention is not limited to this and can be sufficiently applied to the following cases.

(a) A device is installed to detect passengers in car 5, and automatic calls are made only while there are passengers in car 5.

(a) When a certain amount of time has passed since the call was released,
Stop the motor generator that powers the elevator,
The car door is closed, the car interior lights are turned off, and the car waits. After the motor generator has stopped, the car switches to automatic call mode for a specified period of time.

By doing so, even if the passenger is an elderly person or a child who is trapped inside the car 5, it is possible to communicate with the outside without any operation.

As explained above, in this invention, the communication device that communicates between the inside and outside of the car is automatically put into a talking state when the landing button or the car button for disabled people is operated, so even disabled people can easily talk to outsiders. This allows you to use the elevator with peace of mind.
