良に関するものである。
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for operating an elevator in a crime prevention manner.

エレベータのかごは戸が閉まると密室になるの

暴を働く犯罪が多発している。通常かご内には非
常呼びボタンが設けられており、非常の場合乗客

ご内で異常振動が発生したことにより、上記犯行
の発生を検出しようとするものもある。
When the elevator car door closes, it becomes a closed room, and many crimes are taking advantage of this to assault passengers (particularly women). Usually, an emergency call button is provided inside the car, and in case of an emergency, passengers can use this button to notify the outside of an abnormality inside the car. However, if the culprit restrains a passenger, it becomes impossible for the passenger to press the emergency call button. Therefore, in order to prevent this, for example, as shown in Japanese Patent Application Laid-open No. 102481/1981, abnormal movements of passengers in the car are detected by changes in light, and alarm devices, broadcasting devices, nearest floor stopping devices, etc. It has been proposed to operate the Furthermore, there are systems that attempt to detect the occurrence of the above-mentioned crime based on the occurrence of abnormal vibrations within the car.

しかし、乗客は犯人に脅かされたときに必ずし

たり、犯行でないのに犯行と誤検出したりするう
らみがある。
However, passengers do not necessarily make abnormal movements when threatened by a criminal; on the contrary, they often stand still, making it impossible to completely detect the occurrence of a crime. Furthermore, if there is only one passenger in the car, it cannot be guaranteed that the passenger himself will not make abnormal movements. In fact, it is possible that he makes such a move because he feels comfortable and there is no one else on board. Even in such a case, the above-mentioned abnormality detection is performed and the manager is forced to deal with it, which increases the burden on the manager. In other words, there is always a risk that passengers may suffer damage because a crime cannot be detected, or a crime may be mistakenly detected when it is not a crime.

This invention is intended to improve the above-mentioned problem, and when it is detected that there are people outside the predetermined range inside the car, the operation of the car is controlled. To provide a security operation device for an elevator, which performs crime prevention operation of a car only when a person is present.

When the 41 passengers are standing within a predetermined range in front of the in-car operation panel 3 and there is no one else in the area, the passenger detection device contact 5a is open and the crime prevention driving command relay 13 is deenergized. Contact 13a is closed,
Contacts 13b and 13c are open. When the passenger 4 presses the destination floor button on the in-car operation panel 3, the door close command relay contact 8 closes, the door close relay 10 is energized, the car door 2 closes, and the landing door opens in conjunction with this. 7 will also close. Car 1 now runs towards the floor registered with the destination floor button. When the car 1 arrives at the above floor, the door opening command relay contact 9 is closed, the door opening relay 11 is energized, and the car door 2 and the landing door 7 are opened. Since these operations are normal elevator operations, detailed explanations will be omitted.

Suppose that a criminal with some kind of criminal intention against Passenger 4 boarded the vehicle late at night after Passenger 4. At this time, the passenger detection device 5 operates, and the contact 5
a is closed. When the passenger 4 presses the destination floor button, the security timing detection relay contact 12 closes, so the (+)-5a-12-13-(-) circuit
The crime prevention driving command relay 13 is energized and the contact 13a
is opened, and contacts 13b and 13c are closed. Due to the opening of the contact 13a, the door closing relay 10 is not energized even if the door closing command relay contact 8 is closed. on the other hand,
Since the door opening relay 11 is energized by the closing of the contact 13b, the car door 2 and the landing door 7 remain open, and the car 1 does not depart. Therefore, the inside of the car 1 is not kept in a closed room condition, so that crimes can be prevented from occurring. If the criminal enters the predetermined range where the passenger 4 is and attempts to restrain the passenger, the passenger 4 will either put only one foot over the passenger detection device 5 or throw a handbag or the like onto the passenger detection device 5. For example, the car 1 can be easily placed in the door-open standby state as described above.

On the other hand, by closing the contact point 13c, the in-car announcement device 14 is activated, such as "Customer boarding later. Please get off" or "The security device has activated."
etc. will be broadcast. Additionally, the in-car display 15 also operates and displays the same information. Furthermore, the manager's room notification device 16 operates and the manager's room is also notified. As a result, the criminal is deterred from committing the crime and is restrained from carrying out the crime. Moreover, it is possible to give a sense of security to passengers.

Now, car 1 is on the 1st floor, and only 41 passengers get on car 1 and press the destination floor button 20 on the 3rd floor.
(+)-20-26-23-(-) circuit, 3
The car call registration relay 23 on the floor is energized, and the contact 2
It maintains itself by closing 3a. Now, as described above, the door closing relay 10 is energized, the car door 2 and the landing door 7 are closed, the car 1 runs, and stops at the third floor (details are omitted). When car 1 arrives at the third floor, door opening relay 11 is energized and car door 2 and landing door 7 are opened. These operations are similar to those shown in FIG.

Assuming that car 1 is on the third floor late at night and another passenger boards the car after passenger 4, the security operation command relay 13 is energized and the contacts 13a, 13d, 13e are activated, as explained in FIG. is opened, and contacts 13b, 13c, and 13f are closed. When door close command relay contact 8 closes, (+)-24b-8-
The door closing relay 10 is energized by the circuit 10-(-), and the car door 2 and the landing door 7 are closed. At this time, even if passenger 4 has not pressed any of the destination floor buttons 18 to 20, (+)-13f-24a-21
- (-) circuit, car call registration relay 2 on the 1st floor
1 is energized and self-retains by closing the contact 21a. Car 1 now runs towards the first floor,
When arriving at the first floor, the car position relay contact 24a,
24b is open and contact 24c is closed. Contact 2
By opening 4a, car call registration relay 2 on the first floor
1 is deactivated. Further, by opening the contact 24b, the door closing relay 10 is deenergized. Also, contact 2
By closing 4c, (+)-13b-24c-1
Since the door opening relay 11 is energized by the circuit 1-(-), the car door 2 and the landing door 7 are opened and maintained in this state. As a result, the car 1 is released from the closed room state, thereby preventing a crime from occurring. It is desirable that the floor where the door is left open is set to a floor with a manager's office or a floor with a lot of foot traffic.
