Description

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

Elevators in buildings are places where malicious crimes such as theft and sexual crimes are likely to occur. Crimes occur frequently during the day and during off-peak hours, especially late at night, and are particularly vicious. In order to rescue elevator passengers from these crimes, as proposed in the specification and drawings of Japanese Patent Application No. 57-205002, elevators can be operated only when there is only one passenger in the elevator.

Passengers can open or close any of the above doors according to their will.

In addition to minimizing the chances of other passengers getting on board.

Elevator operating systems have been devised that are highly effective in preventing crime and allow passengers to easily escape from the car when another passenger gets on the car.

However, when an elevator user calls the elevator to the floor to switch to crime prevention operation at the landing, there is no way to check whether the elevator car is empty or not, so sometimes a molester may already be inside the elevator car. There was an issue where I was suddenly attacked at the second landing.

This invention was made in view of the above drawbacks.

When the inside of the car is unattended and the elevator can be switched to crime prevention operation, a display means displays this fact to enhance the crime prevention effect.

Hereinafter, specific examples of the present invention will be described. 1st
The figure is a book showing a front view of an elevator landing on the entrance floor to which the security device of the present invention is suitable. There are provided a hall isodicator (2) that displays a message, and a display section (3) that displays that the elevator is in security operation. In addition, 2 (4) is the hall call button installed at the hall, jD, (5
) is a crime prevention operation switch button with a built-in lamp, which is also installed in the landing area.

FIG. 2 is a block diagram showing an example of an elevator security device according to the present invention. In FIG. 2, αQ is a flip-flop that is set by operating the crime prevention operation switching button (5), and its Q output includes an indicator (3) that indicates that crime prevention operation is in progress, and a reset terminal of the flip 70 knob. A lamp with a built-in button (5a) that indicates whether or not crime prevention driving is possible via
, furthermore, an AND gate (to) is connected, and the reset terminal of the flip-flop is connected to the Q output terminal of the flip-flop (I2) via the one-shot multi-vibrator I, and the set terminal of this flip-flop is connected to the The running signal S1 during operation and the fully open door signal S2 are input to the reset terminal.

The one-shot vibrator (II) is activated at the falling edge of the Q output of flip-flop a3, that is, after the car runs, the one-shot vibrator (II)
When it is detected that the door is opened, a reset pulse is sent to the 7 lip-flop OI in the subsequent stage.

In Fig. 2, the part surrounded by broken lines constitutes the circuit means (A) for detecting whether or not crime-prevention driving is possible.
+3 is a call registration storage device (14 is a hall call registration storage device, and the integrated call registration value output from these call registration storage devices (II) and II4 is supplied to a comparator (II). , and the output of the comparator (II) is connected to call detection means consisting of a timer ae which sends out an output signal when the number of registered car calls and hall calls is not greater than a certain value for a certain period of time.

Also, the car weight sensor 6 installed on the floor inside the car? ), the car weight sensor aη generates an output depending on the weight of the passenger, and the output is connected to one input of a comparator (II), and the other input of this comparator (II A reference value vrθf is added to set the output level of the car own weight sensor αη based on the passenger weight, and the output of the comparator +11 is as follows.

Passenger detection means consisting of a timer (11) is connected to the car, which sends an output signal when the weight of the car is below a certain value for a certain period of time.

Above, timer αI, (output of II is or game) C1l
The Q output is applied to the set terminal of the flip 70 knob (to) via the switch, and the Q output when set is a lamp built into the button (5) that indicates that crime prevention driving is possible.
a). Also, the Q output of the 7 lip 70 tube a and the output of the OR gate can be added to the AND gate function.

The output S3 is provided as a broadcast signal for broadcasting to a passenger hall etc. that crime prevention driving is possible, and a crime prevention driving signal for performing crime prevention driving.

Next, the operation of the inventive device configured as described above will be explained.

When a passenger using the elevator presses the security operation switch button (6) installed at the landing on the entrance floor, the signal sets 7 lip 70 knob H, and this flip-flop (1
When set to 1, the Q output becomes ``H2'', which causes the indicator (3) to light up.

A display saying "In security operation" is displayed to indicate that the elevator is in security operation mode.

In this state, press the hall call button (4), get into the car, and then press the car call button (not shown) for the desired floor.

After the elevator door is closed, the car will run toward the registration floor. The running signal S1 at this time is applied to the set end of the flip-flop 0, thereby setting it in the set state.

Then, when the elevator stops at the car call registration floor and the door is fully opened, the door fully open signal is applied to the reset terminal of the 7 flip-flop (IX6), which causes the shift flip-flop H to be applied. At the same time as resetting
At this time, the fall of the Q output triggers the one-shot multivibrator (Ill), and its output resets the shift flip-flop wheel, canceling the crime prevention operation of the elevator and returning to normal operation.

On the other hand, when an elevator passenger arrives at a landing such as the entrance floor, if a call in the elevator car or a hall call remains unregistered for a certain period of time, the call registration storage device (11Q4
), the comparator 0 temperature and timer QQ operate, determining that the elevator can be operated for crime prevention, and sending a signal to the or gate. Furthermore, when the car continues to be empty of passengers for a certain period of time, the comparator 0I
If the reference value Vref is not exceeded, a signal is sent from the comparator 0, and a timer (11) is activated, determining that the elevator can be operated for crime prevention, and sending a signal to the OR gate.

In other words, if at least one of the above-mentioned call registration storage device <13 (14) detects the car weight seven times and it is determined that the elevator can be operated for crime prevention, the output of the or gate is "H". This sets the flip-flop CID. When the flip-flop Qυ is set, its Q output becomes "H" and the built-in lamp (5a) of the security operation switch button lights up. At the same time,
Displays that the elevator can be operated for security purposes. In addition, the output of the OR gate (A) is determined by pressing the crime prevention operation switching button (5), and the AND condition with the Q output "H" of the sent 7 lip-flop sequence is established, so the output of the AND gate (2) is satisfied. ), and broadcasts to the hall etc. that crime prevention driving is possible.When this happens, the above flip-flop a*oq output is added to the flip-flop 70 knob Qυ as a reset signal, and the shift flip-flop a◇ is reset.

The fact that the elevator is in use is indicated to passengers at the landing by turning off the lamp built into the switch button.

According to the above embodiment, when the car is unoccupied.

The lamp (5a) will light up, so press the security operation switch button (5)
When you press the button to activate crime-prevention driving, there is no chance of a criminal act occurring, so you can use the car with peace of mind.

In addition, when it is possible to switch to crime prevention driving, the rung (
Since 5a) lights up, it is also effective for reminding passengers who use the vehicle late at night that they should use it for crime prevention driving.

Yet again. When crime prevention operation is activated, it is displayed on the display (3), so even if multiple elevators are installed, it is easy to select which elevator to use.
It can be used to prevent crimes from occurring.

Note that other embodiments of this invention will be listed.

(a) The switching means for crime prevention driving is not limited to a button, but may also be a switching means using a dedicated magnetic card, a numeric keypad, voice recognition, etc., or a method in which a switch is turned on in a manager's room or the like.

(b) Of the means to determine whether or not crime prevention driving is possible.

The means for detecting passengers in the car is not limited to the one shown in the embodiment, but may be pattern recognition and detection using an ITU, an ultrasonic camera, an optical sensor, or the like.

(0) As a method of displaying whether or not crime-prevention driving is possible, the indicator light may be blinked when crime-prevention driving is possible, or it may be turned off when crime-prevention driving is possible, or it may be turned off when crime-prevention driving is possible. It may be arranged to turn on the light when in the state.

As stated above, when the passenger detecting means activated by the load of the car detects that there are no passengers in the car, or when the car call and landing call detecting means detects that there is no passenger. Since we have decided to display this on the display means, even if a molester is hiding in the car during crime prevention driving, it can be detected from the display contents of the display means and 9 crimes can be prevented from occurring. .
