Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in a security operation device for an elevator.

[Prior art]

In recent years, crimes have occurred in which people assault passengers by taking advantage of the fact that the inside of an elevator car becomes a kind of closed room.9 Various proposals have been made as countermeasures, including the possibility of crimes occurring. When the nighttime detection device is activated at night when the car is called,
By stopping at each floor and opening the door, the situation inside the car can be monitored from the hall, and even if a crime occurs, passengers will have more opportunities to quickly escape from the car. I have to.

In addition, constantly operating each floor will reduce elevator service and prevent criminals from entering from other floors. There is.

However, the car call was pressed fully and the doors began to close.

There is a possibility that a criminal enters the door before it is fully closed, causing the door to close completely. At this time, the first criminal presses the operation release button on each floor all the way, locking up nine passengers and committing violence, causing the operation on each floor to be canceled and reducing the chances for one passenger to escape from the car. In addition, in terms of load conditions, the weight of each person is different, and the release of operation for each floor is uneven depending on the weight of the load, and there is a high risk that a criminal will press the release button after the elevator starts running.

In order to eliminate the above-mentioned problems,
As shown in No. 482, the conventional elevator crime prevention system is equipped with a device to detect abnormalities in car No. 2, and when the device is activated, 9 passengers escape from the criminal after a crime occurs. Therefore, it was not intended to prevent 9 crimes from occurring.

[Overview of the invention]

The present invention was made in view of the above circumstances, and
When the nighttime detection device is activated, by fully pressing the car call button, the car will operate while stopping at each floor until the car call floor (-), and each floor operation canceling device such as a button to cancel operation on each floor is installed. To provide a crime prevention operation device for an elevator, which prevents the car from completely stopping at intermediate floors where criminals are likely to enter the car.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be explained with reference to FIG.

In the figure, (-1-), ←) are DC power supplies, (1) to (4) are stop command relays that, when energized, give the stop finger + to the 1st to 4th floors of the car, (IA) to (4A ] are the contacts of the illuminance detection device (not shown) that open when the brightness of the landings on the 1st to 4th floors is below the specified level, and the stop command relay +1
1 to (4) The first stop command invalidation means to completely invalidate the visitor call registration relay contacts (1B) to (4B) that close when a hall call from the 1st floor to the 4th floor is registered, respectively. , (I
C-(4C, (ID)-(4D) are car call registration relay contacts that close when car calls for the 1st to 4th floors are registered by the destination buttons in the car, respectively.

(1E) to (4E) are car call registration relay contacts that are also opened, (5A) are clock contacts that open and close between 2:00 a.m. and 6:00 a.m., and (5B) are clock contacts that are also open.

Next, the operation of this embodiment will be explained.

At any time other than between 2:00 a.m. and 6:00 a.m.

Clock contact (5A) is open and (5B) is closed.

Therefore, the car is running with no direction.

When deciding to stop the car call, use the car call registration relay contact (
When one or more of 1C) to (4C) are closed and a stop is decided due to a visitor call, the hall call registration relay contacts (1B) to (4B) are closed.
) closes, the stop finger + one or more of the IJ fingers 1) to (4) are energized and the car stops.

Next, between 2:00 a.m. and 6:00 a.m., the 1-clock contact (5A) is closed and the same contact (5B) is open.When the car is currently on the 4th floor and is not being serviced, the 1-clock contact (5A) is closed and the same contact (5B) is opened. When you register a hall call on the 1st floor, the 9 hall call registration relay contact (1B) will close. - (1E) ~ (4E) - (IB) - +11
-←) circuit energizes the stop command relay (11) on the first floor, and the car travels downward and stops on the first floor.

Next, when a passenger who boarded from the 1st floor presses the destination button on the 3rd floor in the car to register a car call, the 3rd floor car call registration relay contacts (5C) and (3D) close and 3E) open. Then, the car starts moving upward. If the brightness of the landing area on each floor exceeds the fidget standard, the illuminance detection contact (
1 person) ~ (4A) close, stop finger + IJ shot 1)
~ (4) The car stops at each floor and ascends to the third floor. Once the car reaches the 3rd floor, there is no other call, so all further operations are stopped, and the car call registration relay contact (5D)
is opened and stop command relays (1) to (4) are deenergized. However, if the brightness of the second floor landing is below the standard and it is difficult to monitor even if a crime occurs, the second floor illuminance detection contact (2A) will be opened and the stop command relay (2) will be activated. The energized watercraft will rise to the third floor without stopping on the second floor. There is also a call number on the second floor, and there is a visitor call registration relay contact (2
Even if B) is closed, the car call registration relay on the 3rd floor
Since it is open, the stop finger on the second floor + IJ relay 2'' will not be energized. In this way, passengers boarding from the 1st floor are able to operate the elevator conditionally on each floor, so that even if a crime occurs inside the building, they have the opportunity to escape from the criminal, while still having the opportunity to escape from the criminal. To protect passengers inside the car from serious damage without stopping the elevator on the floor.

FIG. 2 shows another embodiment of the invention. In addition.

Explanation of the same reference numerals in FIG. 2 as in FIG. 1 will be omitted.

In the figure (1F) to (4F), (IG) to (4G),
(IH) ~ (4H) are each stop command relay fil ~
(4) A stop that opens when it is detected: ln'> IJ sill one point, each stop finger on another floor + IJ sill 1) ~ (
4) completely prevents the energization and the corner does not stop.)
This is second stop command invalidating means.

When the car is currently on the 4th floor and is not being used for operation, when a passenger registers for a hall call on the 1st floor, the arrival call registration relay contact (1B) closes and the stop command relay on the 1st floor is activated. The contacts (1F) to (IH) open.

After a short delay, for example, when the 2nd floor tow call is registered, the hall call registration relay contact (4.(2)) closes, but the stop command relay contact (1F) is open. Therefore, the stop command relay (21) is not energized.

In other words, when Isuneka's hall call is registered, the stop command relay corresponding to that call is deactivated, but the stop command relays corresponding to other hall calls are not activated. The car goes directly to the floor where the first call was made.The operations after the passenger gets into the car are as described above. In this way.

By giving passengers who are afraid of crime the right to preferential treatment, it is possible to provide both practical and psychological relief. Furthermore, after the car arrives at the destination floor in response to a car call, the stop command relay is de-energized, so it goes without saying that the second and subsequent landing calls must be answered.

〔Effect of the invention〕

As described above, this invention is based on one latent Vζ in which the car stops.
An illuminance detection device is installed, and all cars are stopped on floors where the illuminance detection device detects brightness that exceeds the specified value, regulation 1iI.
) On the following brightly lit floors, we have provided a 1° stop phase ◆ nullification means to prevent the work from stopping, which has the effect of preventing criminals who are usually lurking around town from invading the cage.
