Description

[Detailed Description of the Invention] This invention relates to an improvement of a security device for an elevator.

Recently, crimes in elevator cars and on landings have become a major social problem, and a monitoring system for effective crime prevention is desired.

Conventionally, as a security device for elevators, a system of monitoring using a television camera as shown in FIG. 1 has been proposed. In this FIG. 1, 1 is an elevator car, 2 is a television camera that monitors the inside of the elevator car 1, and this television camera 2 is
It is placed in a corner of the ceiling inside car 1 so that it can take pictures of everything inside. Reference numeral 3 denotes an elevator landing, and a television camera 4 is installed on the ceiling of the elevator hall so that the situation of the elevator hall 3 can be monitored.

The frequency of crimes occurring inside elevator cars or at landings is much higher in elevator cars than at landings.
It cannot be said that there are no crimes occurring on boarding stations. Therefore, in order to monitor both the inside of the car and the landing area with a television camera for crime prevention, it is necessary to install the television camera both inside the car and at the landing area, as shown in FIG. In addition, there are many elevator landings depending on the number of floors, so the method shown in FIG. 1 requires many television cameras, which has the drawback of requiring large-scale and expensive security equipment.

This invention eliminates the drawbacks of the prior art and provides an elevator security system that can monitor both the inside of the car and the landing using a single television camera installed inside the car.

Hereinafter, specific embodiments of this invention will be described based on the drawings.

Figures 2 and 3 show an example of an elevator security system according to this invention, in which a television camera 2 is installed on the ceiling of an elevator car 1, located on the side of the car entrance. 2 is arranged so that when the elevator door 5 is opened, the situation of the landing 3 can be photographed through the entrance and exit, and when the elevator door 5 is closed,
In the part of the door 5 facing the TV camera 2,
A reflecting mirror 6 that reflects the situation inside the car 1 is provided, and the situation inside the car 1 is photographed through this reflecting mirror 6.

In the security device configured as described above, when the elevator door is closed, the situation inside the car 1 is reflected on the reflector 6 as shown in FIG.
If you shoot the image inside on TV camera 2, you can
You can monitor what's inside. Further, when the elevator car 1 arrives at the landing and the door 5 is opened, the television camera 2 can photograph the situation in the landing 3 as shown in FIG.
In other words, one TV camera 2 installed inside the car 1
This means that the inside of the car and the landing area can be monitored.

In general, crimes in elevator cars overwhelmingly occur after the doors are closed and the inside of the elevator car becomes a closed room. Even if the situation inside the room is captured by a television camera, the crime prevention monitoring effect is sufficient.

Note that the reflecting mirror 6 installed inside the car door 5 may be a convex mirror. In this case, the entire situation inside the car 1 can be shown on the television camera.
Further, the reflecting mirror 6 may be constructed by mirror-finishing a predetermined area of the door 5 facing the television camera 2. This case is effective when there is not enough space to install a reflecting mirror.

As explained above, according to this invention, it is possible to monitor crime inside the car and the landing area with a single TV camera installed inside the car, and there is no need to install a TV camera in the landing area as in the past. This has the effect of simplifying the crime prevention monitoring equipment and significantly reducing costs.
