Abstract

(57) [Abstract] [PROBLEMS] To provide a crime prevention driving device for an elevator, which prevents a crime in the elevator by preventing the passenger from driving to another floor by the passenger's own operation when the elevator stops at a specific floor. . SOLUTION: A normally-closed contact FLb of a switching relay that operates when an elevator stops at a specific floor disables a door-close button CB1 of an operation panel in a car, and a normally-open contact FLa that closes when a specific floor is detected. This activates the door close button CB2 provided on the hall side of the specific floor. In this state, the door close command circuit 1 that issues a door close command when the hall side door close button CB2 is operated is provided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator crime prevention operation system, and more particularly to an elevator crime prevention operation system for controlling opening and closing of an elevator door.

[0002]

2. Description of the Related Art An elevator stopped at a door opening / closing level opens a door when a car is pressed on a floor button when the car is stopped, and then a predetermined time elapses or a passenger enters the car. The door is closed by a passenger operating a door-closing button on the operation panel in the car.

Regarding the technology for crime prevention operation of this elevator, Japanese Laid-Open Patent Publication No. 63-242889 and Japanese Utility Model Laid-Open No. 61-1 are available.
The disclosure is recognized in Japanese Patent No. 51972, etc.

[0004]

In the above-mentioned conventional elevator, even in an elevator having a reception on the middle floor of a building, for example, a passenger in the car operates the door close button to get off at the reception floor. You can freely drive to another floor by closing the door again.

The present invention has been made in view of the current state of door-closing operation by passengers in a car for an elevator stopped at a specific floor as described above, and an object thereof is to make an elevator stopped at a specific floor. On the other hand, it is another object of the present invention to provide an elevator crime prevention operation device capable of controlling the closing of an elevator door at the hall.

[0006]

In order to achieve the above object, the present invention relates to an elevator for opening and closing a door of an elevator by operating a door opening and closing button provided on an operation panel in an elevator car. , Provided a door-close button in a specific floor of the elevator, if the elevator car is stopped at the specific floor, the door-close button provided in the elevator car operation panel is invalid, to the specific floor The door closing operation of the elevator is performed only by operating the provided door closing button.

With such a structure, when it is detected that the elevator car has stopped at a specific floor, the door closing button switching means is activated to invalidate the door closing button on the elevator car operation panel, and the specific floor platform The door close button of becomes effective. Therefore, even if the passenger in the elevator car performs the door closing operation, the door closing operation is not performed, and thus it is possible to prevent driving to another floor.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a circuit diagram showing an embodiment of the crime prevention operation apparatus for an elevator according to the present invention.

As shown in FIG. 1, a normally open contact CB1, a normally closed contact FLb, and a door close command circuit 1 are connected in series between the DC power supply terminals P and N. Further, a series circuit of the normally open contact CB1 and the normally closed contact FLb and a series connection circuit of the normally open contact CB2 and the normally open contact FLa are connected in parallel with each other.

Here, the normally open contact CB1 is a normally open contact of a door closed button provided on the operation panel in the car, and the normally open contact CB2 is a normally open contact or normally open contact of a door closed button provided at a specific floor. FLa and normally closed contact FLb are contacts of a relay (not shown) that operates when a specific floor is detected. The door closing command circuit 1 has a function of controlling the closing operation of the elevator door.

In the embodiment having such a structure, the normally-open contact CB2 corresponds to the means for performing the door closing operation in the landing of the invention, and the normally-open contact FLa and the normally-closed contact FLb are at the specific floor of the invention. It corresponds to the means for switching the door close button inside and the door close button at the hall.

Next, the operation of the embodiment will be described.

When the elevator car is stopped at a place other than a specific floor, the DC power supply terminal P, the normally open contact CB1, and the normally closed contact FL are operated by operating the close button CB1 on the operation panel in the car.
b, the door close command circuit 1, and the DC power supply terminal N form a closed circuit, and the elevator door performs the closing operation.

In the present embodiment, when the elevator car stops at a specific floor, the normally closed contact FLb opens and the normally open contact FLa closes. At this time, even if the passenger in the car operates the door close button CB1 on the operation panel, the circuits of the DC power supply terminal P, the normally open contact CB1, the normally closed contact FLb, the door close command circuit 1 and the DC power supply terminal N are Because it is not formed, the elevator door remains open. Therefore, the passenger in the car cannot drive to another floor and stops at that floor.

Next, when the door close button CB2 provided in the hall is operated, the DC power supply terminal P, the normally open contact CB2, and the normally open contact FL.
A, the door closing command circuit 1 and the DC power supply terminal N form a closing circuit, and the elevator door can perform the closing operation.

[0017]

As described in detail above, in the present invention, for the elevator stopped at a specific floor, the door closing operation by the passengers in the car is prevented and the door closing operation is controlled at the hall side. It is possible to prevent crimes caused by passing through a specific floor and escaping to another floor.
