JPH06329354A - Crime preventive operating device for elevator - Google Patents

Abstract

PURPOSE:To enhance the sense of safety of a user of an elevator, which is put in the solely dedicated operation for calls with a crime preventive operation command switch furnished on each elevator hall, by installing a sensing means for existence of any user in a specified region of a hall and another sensing means for any intruder from outside of the region, and suppressing door closing when the latter is sensed. CONSTITUTION:When a user pushes a call button 2 at an elevator hall while the crime preventive operation is made with a crime preventive operation command switch 3, or when elevator arrives in response to the call button 2, an automatic guide broadcasting device 4 gives announcement that the operation is under crime preventive mode, that a person coming later should move to the region of the floor 10, and that the elevator door remains without shutting if transit is made from the floor 10 to floor 9 after arrival of the elevator. The door open standby takes place until the shut button in the car is pushed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crime prevention operation system for an elevator, which protects passengers who use the elevator from a molester or a thug.

[0002]

2. Description of the Related Art As described in Japanese Patent Application Laid-Open No. 61-197384, the elevator is operated as a single passenger in a time zone where night crimes are likely to occur, and when there are two or more persons who may be involved in a crime, There is a crime prevention driving device by stopping and keeping the door open.

[0003]

SUMMARY OF THE INVENTION In the above-mentioned prior art, the focus is only on not getting on a stranger, and no consideration is given to getting on an elevator.
If the person who uses the elevator is standing in front of the elevator platform, especially at a position where he / she can immediately get into the elevator, the person who uses the elevator first feels anxiety, a sense of crisis, or a psychological situation. I feel sorry about this and cannot board smoothly.

The object of the present invention is only when it is detected that there is no user other than an arbitrary area of the elevator hall.
By allowing the door of the crime prevention elevator to be closed, it is to provide the crime prevention operation of the elevator that the user can use with peace of mind.

[0005]

[Means for Solving the Problems] In order to achieve the above object, in an elevator in which a crime prevention operation command switch provided in an elevator hall is used to perform a car call-only operation, a predetermined area in front of the elevator hall is A means for detecting the presence or absence of a user in the area, a means for detecting the intrusion of a person from outside the area, a means for suppressing the elevator door closing when detecting the intrusion of a person from outside the area, and the crime prevention driving The automatic guide broadcasting device is provided to broadcast to the user at the hall when the command is issued or when the elevator arrives and the elevator arrives in response to the elevator call button at the time of crime prevention driving.

[0006]

[Function] During crime-prevention driving, when a person or a group is used to meet another person or other group at the elevator hall, the person or group who will use it later must leave the predetermined area in front of the elevator hall, and the person who uses the elevator first or When the group boards the elevator, if the subsequent user detects an intrusion into a predetermined area in front of the elevator landing, the door closing of the elevator is suppressed, and only when it is not detected, the door closing of the elevator is permitted.

As described above, during the crime prevention driving, the user who first uses the elevator can safely close the door because the user behind the elevator is at a position away from the latter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a landing showing an embodiment of the present invention. FIG. 2 is an explanatory diagram of a user detection device installed in a hall showing an embodiment of the present invention. FIG. 3 is an explanatory diagram of a photoelectric device installed in a hall showing an embodiment of the present invention. FIG. 4 is a flowchart showing a control method according to an embodiment of the present invention.

In FIG. 1, 1 is a landing door, 2 is an elevator call button, 3 is a crime prevention operation command switch, and 4 is an automatic guide broadcasting apparatus for informing a user at the hall when a crime prevention operation is in progress. , 5 and 6 are user detection devices provided on the wall portion to detect the presence or absence of a user before the elevator hall, and 7 and 8 are the floor 9 which is the detection area of the user detection devices 5 and 6 and are detected. This is a photoelectric device for detecting the movement of a person at the boundary with the floor 10 outside the area (hereinafter, the area of the floor 9 is referred to as the area 1, and the area of the floor 10 is referred to as the area 2).

As shown in FIG. 2, the user detection devices 5 and 6 are each composed of a plurality of photoelectric devices paired with each other, such as 5a and 6a and 5b and 6b, arranged at intervals so that a human body can be detected. When the device is blocked, the presence of the user can be detected.

As shown in FIG. 3, the optoelectronic devices 7 and 8 are 7a.
And 8a, 7b and 8b are respectively composed of two optoelectronic devices that are paired, and the moving direction of a person can be detected by how the optoelectronic devices are blocked.

Next, the operation of the embodiment having the above construction will be described.

When a crime prevention operation is instructed by the crime prevention operation command switch 1, when the user pushes the elevator call button at the elevator hall, or when the elevator arrives in response to the elevator call button, the automatic guide device. According to 4, the elevator is in crime prevention operation for users at the elevator hall. Those who will use it later must move to Area 2. After entering the area 1 from the area 2 after the arrival of the elevator, the elevator broadcasts that the door will not be closed. When the elevator arrives, the main broadcast is repeated until the elevator departs.

After arrival, the elevator waits for the door to open until the close button in the car is pressed.

Next, the user confirms that there is no other person or other group in the area 1, gets into the elevator, and presses the door closing button to start the door closing operation.

After the door is closed, the elevator performs a direct drive to the destination floor by a car call dedicated operation.

After the arrival of the elevator, when it is detected by the photoelectric devices 7 and 8 that a person moves from the area 2 to the area 1, the door close button is invalidated and the door open standby state is returned to.

The cancellation of invalidity of the door close button is performed by the photoelectric devices 7 and 8
By this, it is detected that a person has moved from the area 1 to the area 2, and the user detection devices 5 and 6 detect that there is no person in the area 1.

In this embodiment, the crime prevention operation command switch 3 provided in the hall issues a crime prevention operation command. However, it is also easy to instruct the operation by a time command using a 24-hour timer or the like. it can.

Further, when the crime prevention operation is performed, the elevator is left in the open state and the intrusion of a person is detected in the area 1 as a trouble. It is also easy to issue a signal.

[0022]

According to the present invention, during crime prevention driving, an elevator user gets into an elevator in a state where another person or another group moves to a distant position when he or she collides with a user of another person or another group at the elevator hall. be able to.

When a person intrudes into a predetermined area in front of the elevator landing at the time of getting on the elevator, the door closing of the elevator is invalidated and the door is opened, so that the user can use the elevator at ease. be able to.
