Description

[Detailed description of the invention] This invention relates to a crime prevention device for an elevator to prevent crimes occurring inside a car.

When the elevator car door closes, it becomes a closed room.
Due to this feeling of being in a closed room, there are many crimes involving violent acts against mainly female passengers late at night when there are fewer passengers.

In order to prevent such crime inside the car, conventional methods include installing glass in part of the door so that the inside of the car can be seen from the outside, or stopping the car on the way to the destination floor regardless of whether the car is called or not. Countermeasures have been taken to eliminate the feeling of being in a closed room inside a car, such as by practicing safe driving (hereinafter referred to as crime prevention driving).

However, since crimes mainly occur late at night when there are few customers, there has been a problem in that the above-mentioned measures alone cannot be a sufficient means to prevent crimes inside cars.

This invention was created in view of the above-mentioned problems, and the purpose is to prevent crime inside the car by broadcasting crime prevention broadcasts inside the car at night.

Figures 1 and 2 show an embodiment of this invention, in which 1 is a car, 1a is a door for opening and closing the entrance of this car 1, and 2 is a door for opening and closing the entrance/exit of the car 1, and 2 is a lower transverse member for connecting the car 1 through a vibration isolating rubber 3. The supporting window frame-shaped car frame 4 has an upper end connected to a main rope (not shown), a lower end passing through the upper transverse member of the car frame 2, and pushing the car frame 1 inwardly through a push spring 5. Thimblerod, supported by
6 is a support plate fixed to the lower end of this thimble rod 4, and 7 is a well-known scale provided between this support plate 6 and the upper transverse member of the car frame 2, which converts the amount of deflection of the push spring 5 into an electric signal. A device 8 is a passenger number detection means that operates when the signal from this weighing device 7 becomes a signal corresponding to when two or more passengers are on the car 1, and 9 is a passenger number detection means that operates when this passenger number detection means 8 is activated. An energized output relay, 9a is a normally open contact of this output relay 9, 10 is an operating means consisting of a well-known security operation device that is energized at night and stops the car 1 at each floor up to the destination floor, 10a is an operating means for this Contacts 11 that are closed when the security driving device 10 is energized;
(+ ), (-) are control power supplies.

In the elevator security device configured as described above, the security operation device 10 is not energized during the daytime, so the contact 10a remains open. Therefore, the broadcasting means 11 remains de-energized, and the crime prevention broadcast is not played from the speaker 12.

At night, when the security driving device 10 is energized, the contact 10a is closed. At this time, if only one passenger is on the car 1, the passenger number detection means 8 will not operate, so the output relay 9 will remain de-energized and its normally open contact 9a will also remain open. . Therefore, the broadcasting means 11 remains de-energized, and no crime prevention broadcast is played from the speaker 12.

Next, when two passengers are on the car 1 at night, the passenger number detection means 8 operates via the scale device 7 to energize the output relay 9 and close the normally open contact 9a. As a result, (+)10a-9a-1
The broadcast means 11 is energized by the circuit 1-(-), and a crime prevention broadcast, for example, ``This elevator is currently under security surveillance'' is broadcast to the car 1 from the speaker 12. When a passenger gets off the car 1, the output relay 9 is deenergized and the broadcasting means 11 is deenergized, so that the broadcasting stops.

According to the above embodiment, the crime prevention broadcast is broadcast to car 1, so even if a passenger with criminal intentions gets on the car, the crime prevention broadcast can make them change their criminal intentions and prevent a crime. It is possible.

FIG. 3 shows another embodiment of this invention, in which 20 is a well-known control device for raising and lowering the car 1, and 20a is an operation detecting means which is an output contact of this control device 20, and the car 1 is being raised and lowered. It is something that is closed. 21 is a door control device that opens and closes the door 1a;
1a is a door open detection means that is closed by the door control device 20 from when the door 1a starts to open until the door 1a is completely closed; and 22 is an operation means consisting of a clock device, which is used to detect a predetermined time at night. This closes the time contact 22a.

That is, when the car 1 is operated during a predetermined time period at night, the broadcasting means 11 is energized regardless of whether or not there are passengers on the car 1, so that the weighing device 7 shown in FIG. Since the broadcasting means 11 is energized even in the case of a light passenger who cannot operate the broadcasting means 11, the intended purpose can be achieved.

Furthermore, since it is broadcast even when a passenger is alone, it can give the passenger a sense of security. Further, when the door 1a starts to open, the door opening detection means 21a is closed and the broadcasting means 11 is energized, and the broadcast is made before the user gets into the car 1, giving a sense of security.

As described above, this device is designed to prevent criminal acts when the automatic or manual operating means is operating, and when a predetermined number of passengers or more are in the car, the passenger number detection means is activated. or when the car is operated and the operation detection means is activated, or when the door that opens and closes the entrance to the car is opened and the door open detection means is activated, the broadcasting means is energized to broadcast a security broadcast to the car. This has the effect of preventing crimes inside the cage.
