Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator security operation device that protects passengers using the elevator from molesters, thugs, etc.

Conventionally, this type of elevator security operation device has been simple, in that by turning on a specially installed switch, the elevator is stopped at each floor while there is a car call. Currently, it takes a long time to arrive and is rarely used. In addition, such a method could not be expected to be very effective in protecting passengers from molesters and the like. Therefore, a crime prevention operation command device is installed at the landing or inside the car, and when this crime prevention operation command device is activated, the number of passengers who can get into the car is limited to 18 people, and the car is not activated if more than 2A passengers have boarded the car. A crime prevention device has been proposed for a 5K elevator in which when the operation command device is activated and a single person is detected, the elevator goes straight to the destination floor without responding to a hall call on an intermediate floor.

However, with these crime prevention driving devices, the main focus is on demonstrating the crime prevention effect after switching to crime prevention driving. However, if an elevator is attacked as soon as the door is opened, even if such an elevator is equipped with a crime prevention operation command device, the passenger cannot be protected from crime.

This invention was made in view of the above-mentioned busy situation.
Elevator security operation device with high crime prevention effect that only responds to cars that are not molesters in the called car, such as when there are no other passengers in the car or when the car is not responding to other calls. The purpose is to provide The present invention will be explained below based on the drawings.

The drawing is a circuit diagram of an elevator security operation device showing an embodiment of the present invention. In the figure, the elevator service floors are the 1st to 5th floors, and the crime prevention operation command button is set to 1.
This shows a case where it is installed at a landing on a floor.

In the figure, (+) and (-) are DC power supplies, and 1 is when the destination button for the 1st to 5th floors in the car is not pressed (11a).
~15a is the normally closed contact of the destination button call registration relay for the 1st to 5th floors), which energizes and detects that there are no passengers in the car; 2 is the ascending direction for the 1st to 4th floors; When the landing buttons are not pressed on all floors (218 to 24a are the normally closed contacts of the upbound hall call registration detection relays for the 1st to 4th floors), the upbound hall call non-registration detection relay is energized;
energizes when the exit direction landing button for the 2nd to 5th floors is not pressed on all floors (32a to 35a are the normally closed contacts of the exit direction hall call registration relay for the 2nd to 5th floors). Detection relay 6 is the in-car passenger detection relay 1. Upbound hall call non-registration detection relay 2. Then, the unregistered exit ring 3 is energized, and the normally closed contact 4a of the upbound travel relay (not shown) and the normally closed contact 5a of the downbound travel relay (not shown) are closed. 7 is a crime prevention driver command button provided at the landing on the first floor; 8 is a landing crime prevention driving command relay that is activated by the security driving command button 7; 9 is a crime prevention driving command relay that is activated when the car is x

- Normally open contact 3a - Normally closed contact 4a - Normally closed contact 5a - Crime prevention operation enable command relay 6 - The crime prevention operation enable command relay 6 is energized by the power supply (-) circuit, and it is determined that crime prevention operation is possible. can. At this time, when you press the crime prevention driving command button 7, the power supply (+) - crime prevention driving command button 7 - normally open contact 6a
- Landing crime prevention operation command relay 8 - The power supply (-) circuit is closed and the landing crime prevention operation command relay 8 is energized. At this time, if a car is waiting at a landing other than the first floor, the first floor car Since the normally closed contact 9 of the position detection relay is closed, it is self-maintained by the circuit of power supply (+) - normally closed contact 9 - normally open contact 8a - hall crime prevention operation command relay 8 - power supply (-), and the crime prevention A driving command is issued and the car is called to the first floor. When the car arrives at the first floor, the normally closed contact 9 of the car position detection relay is activated.
is opened, and the self-holding circuit of power supply (+) - normally closed contact 9 - normally open contact 8a - hall security driving command relay 8 - power supply (-) is opened, and hall security driving command relay 8 is deenergized. Therefore, when the security operation command button 7 is pressed at the first floor landing, the car is called to the first floor landing after detecting that there are no passengers in the car.

Above, we have explained the cases in which crime-prevention driving is possible.
If the destination button for the second floor is pressed, the normally closed contact 13a of the destination button call registration relay for the third floor opens and the power supply (normally closed contact 11a - normally closed contact 12a - normally closed contact 13a
- Normally closed contact 14a - Normally closed contact 15a In-car passenger detection relay 1 - Power supply (-)\ circuit is opened and in-car passenger detection relay 1 is deenergized. When the in-car passenger detection relay 1 is deenergized, its normally open contacts 1 & are opened, and the power supply (+) - normally open contacts 1
a - Normally open contact 2a - Normally open contact 3a - Normally closed contact 4a - Normally closed contact 5a - Security operation enable command relay 6 - The power supply (-) circuit is opened and the crime prevention operation enable command relay 6 is deenergized. Due to the de-energization of the security operation enable command relay 6, its normally open contact 6a
is opened, and the circuit of power supply (+) - crime prevention operation command button 7 - normally open contact 6a - landing crime prevention operation command relay B - power supply (-) is opened and the hall crime prevention operation command relay 8 is not energized. Therefore, when it is detected that there is a passenger in the car, even if the crime prevention operation command button 7 is pressed, the car will not be called to the first floor landing for crime prevention reasons.

Various modifications of this invention will be listed below.

(a) As the crime prevention driving command device at the landing, a specific button may not be provided, but a button installed at the landing or the Kf near it, an automatic detection device, a block sign using a numeric keypad, etc. may be used.

(b) In the above embodiment, the presence or absence of passengers in the car is detected by the presence or absence of destination button call registration, but a car floor frame, an automatic passenger detection device, or the like may be used.

(c) When the crime prevention driving command device is activated, means may be provided for notifying a landing button whether or not crime prevention driving is possible.

(d) Even if the crime prevention operation command device at the optional landing is activated and prevents the car from being called by the crime prevention operation prevention signal, the destination floor of the passenger in the car may still match the above-mentioned landing. A means may be provided to notify this and to alert waiting customers.

tel When multiple cars are installed and there are multiple cars available for security operation, it is possible to specify which car is closest to the floor where security operation is possible or according to a pre-specified selection order. A means for selecting and specifying an optimal security driving car from among the cars may be provided.

Since the VC1fl is configured as described above, the above embodiment is provided with a landing button crime prevention operation command device, and when the device operates to call a car, it is necessary to confirm that there are no other passengers in the car or that the car is A crime prevention system that responds to the above-mentioned landing after confirming that the car is safe and free of molesters, etc., such as that the car is not responding to a call, and prevents crimes against passengers waiting at the landing from inside the car. It becomes a highly effective elevator security operation device.

Additionally, the incidence of building calls during the day is higher than at night, and crime is less likely to occur. Therefore, with the operating device according to the present invention, the frequency with which the crime prevention operation enable command is output is low, and the decrease in elevator operation efficiency, which is a disadvantage of single-seater crime prevention operation, can be suppressed. On the other hand, at night, when crimes are more likely to occur, the occurrence rate of calls is low.Therefore, it is clear that the crime-preventive driving command is output more frequently and the crime-prevention effect increases.

As explained above, the elevator security operation device according to the present invention is provided at or near the elevator landing, and includes a means for manually or automatically commanding the elevator security operation, and a means for manually or automatically commanding the elevator security operation, This system has an excellent effect of extremely high crime prevention effect because it consists of means for calling only cars that satisfy the above conditions to the landing area.
