Description

[Detailed explanation of the idea]

[Industrial Application Field] The present invention relates to an emergency call device installed in an elevator car. [Prior Art] A conventional emergency call device will be explained with reference to FIG. The figure is a front view of the car operation panel provided in the elevator car, with 1 to 6 being destination floor call buttons for the 1st to 6th floors, 7 and 8 being door open and door close buttons, respectively, and 9 and 10 being respectively. Ascent and descent direction lights, 1
1 is an intercom, and 12 is an interphone call button, which corresponds to an emergency call button that activates an emergency call device. Although not shown, an emergency bell button may be provided in addition to the intercom call button 12. Next, the operation of the above conventional emergency call device will be explained. If a car stops mid-floor due to a power outage or malfunction, and a passenger is trapped inside the car, or a crime occurs inside the car, the passenger inside the car should press the call button 12.
When pressed, a buzzer or the like provided in the manager's room will sound while the call button 12 is pressed, and if you pick up the intercom receiver in the manager's room, you can talk between the intercom 11 and the manager's room, etc. It is something that becomes. [Problems to be solved by the invention] The conventional emergency call device described above had the following drawbacks. As shown in FIG. 4, the call button 12 is small, so it is difficult to press when the user is in a hurry, such as when a crime occurs. Even if the call button 12 is pressed, it cannot be confirmed from inside the car that the call button 12 has been pressed, which gives the passengers a sense of anxiety. The buzzer etc. in the manager's room etc. will only ring while the call button 12 is pressed, so in order to reliably connect to the manager's room etc., the buzzer etc. will ring for a certain period of time.
You need to keep pressing 2. However, when a person is in a hurry, such as when a crime occurs, the call button 12 may only be pressed momentarily, and the manager or the like may not notice. [Means for solving the problem] In order to solve the above-mentioned drawbacks of the conventional technology, the present invention increases the size of the call button, attaches an answering light, and, once the call button is pressed, retains the signal for a certain period of time. This is what I did. Furthermore, if the call button is pressed again within a predetermined time after the call button is pressed once, the above signal is continuously held, and the controller etc. is reliably notified that an abnormality has occurred in the car. It also has the effect of preventing tampering. [Example] An example of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a front view of a car operation panel equipped with an emergency call device according to the present embodiment. Reference numeral 20 indicates an intercom call button which is an emergency call button, and the same reference numerals as in FIG. 4 indicate the same elements. Figure 2 shows the operating circuit of the emergency call device, where RY1a is the normally open contact of relay RY1,
RY2a and RY2b are normally open contacts of relay RY2,
RY3a is the normally open contact of relay RY3, RY3b is also the normally closed contact, TRY1, TRY2, and TRY3 are recovery delay relays, and the setting time is TRY1<TRY
2<TRY3. TRY1a, TRY1c
is a normally closed contact of delay relay TRY1, TRY1b is also a normally open contact, TRY2a is a normally open contact of delay relay TRY2, TRY3a is a normally closed contact of delay relay TRY3, and TRY3b is also a normally open contact. RES
is a reset button, L is a response light built into the call button 20, B is a buzzer installed in the car and the manager's room, R is a resistor, C is a capacitor, D1, D
2 is a diode, and P and N are DC power supplies. Now, when a passenger in the car presses the call button 20, P-2
Relay by circuit of 0-TRY3a-RY1-N
RY1 is energized, its contact RY1a is closed, and delay relays TRY1, TRY2, and TRY3 are energized.
And these delay relays TRY1~TRY3
When the passenger finishes pressing the call button 20, the relay RY is activated.
Even after 1 is demagnetized, the energized state is maintained for each set time. When delay relay TRY1 is energized

The response lamp L lights up and the buzzer B sounds by the circuit in [Formula]. When the set time expires and the delay relay TRY1 is demagnetized, its contact TRY1b opens, so the response light L goes out and the buzzer B stops sounding. Also, since contact TRY1c closes, The relay RY3 repeats energization and demagnetization with a time constant determined by the resistor R and capacitor C by the circuit. Therefore

[Effect of idea]

As is clear from the content explained above, the present invention has the following effects. The call button on the emergency call device has been made larger, making it easier to press even when you are in a panic, such as when a crime occurs. When the call button is pressed, a response light, buzzer, etc. is used to notify the inside of the car that the emergency call device is activated, giving passengers a sense of security and preventing the call button from being pressed again due to mischief. Prevent things from happening. If the call button is pressed even for a short time, the emergency call device operates for a predetermined period of time, so it can be operated reliably even in a panic such as when a crime occurs. If the call button is pressed again within a predetermined time after the call button is pressed, the emergency call device continues to operate until it is manually reset, so that contacting the manager etc. can be made more reliably.
