JP2510706B2 - How to unlock the building door - Google Patents

Description

The present invention relates to a method of unlocking a door of a building, and more particularly to a method of unlocking a door of a building where a home elevator is installed.

<Prior Art> In a shared building such as a building, the elevators are installed in a common section, and each room is entered using a key different from the door door of the building. For this reason, in order for maintenance personnel to enter the building when the elevator is out of order, the maintenance company will store the key of the door of the building, or ask for the secret code for unlocking the electric lock of the door, When a failure occurs, maintenance personnel are allowed to enter the building.

A device related to this is proposed in, for example, Japanese Utility Model Laid-Open No. 56-47866.

In addition, a home elevator, which has recently been installed, is also provided with a communication device for making a notification from a car to a maintenance company when a failure occurs.

Therefore, even when a failure occurs in the home elevator, the maintenance company visits the building in which the home elevator is installed from the maintenance company by the notification and performs the failure recovery work.

<Problems to be solved by the invention> In the building in which this home elevator is installed, the inside of the doorway of the building is a residence, so unlike the shared building, the maintenance company keeps the key and the doorway of the doorway is different. I can't let you know your PIN. Therefore, a maintenance worker who goes to the work of recovering from the failure enters the building by having the family member open the door of the building and restores the home elevator.

In this case, if all the family members happen to go out, or if a person trapped in the malfunctioning home elevator lives alone, the maintenance personnel cannot enter the building, and the repair work for the home elevator is not possible. Rescue work of the stowed person will be delayed.

The present invention has been made in view of the current state of restoration work for a home elevator failure as described above, and the purpose thereof is to have a maintenance staff of a maintenance company lock a door of a building when a home elevator accident occurs. The purpose of the present invention is to provide a method of unlocking the door of a building, which can be unlocked to enter the building, perform home elevator failure recovery work, and rescue the person trapped in the car.

<Means for Solving the Problems> In order to achieve the above object, the present invention relates to a method for unlocking a building door for a building in which a home elevator is installed, in which a failure detection signal is issued when the home elevator fails. The lock of the door of the building is unlocked when an unlocking signal input from the outside of the building is input.

<Operation> In the present invention, when a failure occurs in the home elevator, the home elevator issues a failure detection signal. Also,
When a user trapped in a car reports the occurrence of an accident to the maintenance company using the communication device in the car, the maintenance company goes to the building where the home elevator is installed by the maintenance company.

Then, when the maintenance staff inputs an unlocking signal from the outside of the building to the door of the building entrance / exit, this unlocking signal and the failure detection signal from the home elevator are input, thereby locking the door of the building. The lock is released.

Therefore, the maintenance staff enters the building and performs a work of recovering from the failure of the home elevator, and rescues the user who is trapped in the car.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to FIG.

Here, FIG. 1 is a block diagram showing the construction of the unlocking device for the door of the building used in the embodiment of the present invention.

As shown in FIG. 1, a telephone 9 is provided in the car 7 of the home elevator installed in the building, and the telephone 9 is connected by a telephone line 8 to a maintenance company (not shown).

Further, the home elevator is provided with an elevator control panel 5 connected to the car 7 by a signal line 11, and a failure detection device 6 is connected to the elevator control panel 5.

On the other hand, an electric lock 2 is attached to the door of the building where the home elevator is installed, and the controller 1 controls the locking / unlocking of the electric lock 2 by connecting the electric lock 2 to the electric lock 2 by a signal line 14. There is. The electric lock 2 is provided with a keyhole 12, and the electric lock 2 can be locked and unlocked by inserting the key 4 into the keyhole 12 and manually operating the key 4.

A numeric keypad 3 for inputting a personal identification number is provided in the vicinity of the electric lock 2, the numeric keypad 3 and the controller 1 are connected by a signal line 13, and the failure detection device 6 is connected to the controller 1 by a signal line 15 and the controller 1 is connected to the controller 1. Bell 10 is connected.

The keyhole of the electric lock 2 is used to lock or unlock the building in which the home elevator is installed during normal times.
The key 4 is inserted into 12 and it is operated manually.

When the home elevator breaks down and the user is trapped in the car 7, the failure detection device 6 connected to the elevator control panel 5 detects the occurrence of an accident, and the failure detection device 6 outputs a failure detection signal. This failure detection signal is the signal line
It is input to the controller 1 via 15.

On the other hand, the user trapped in the car 7 notifies the elevator maintenance company of the occurrence of the accident through the telephone line 8 by using the telephone line 9. Upon receiving this notification, the maintenance company prepares the equipment necessary for the repair work of the home elevator failure and goes to the building where the home elevator is installed.

When the maintenance staff arrives at the target building, he pushes the doorbell on the door of the building and enters the building through the door opened by the housekeeper to restore the failure of the home elevator.

In this case, even if the doorbell of the door of the building is pressed and there is no response, and it is confirmed that there are only users who are trapped in the car 7 in the building, the maintenance personnel operates the numeric keypad 3. , Enter the predetermined secret code.

When the personal identification number thus input is correct, an unlocking signal is input from the ten-key pad 3 to the controller 1 via the signal line 13.

In this case, the controller 1 already has the failure detection device 6
Therefore, since the failure detection signal is input, the failure detection signal and the unlock signal are input to the controller 1. Thus, when the failure detection signal and the unlocking signal are input to the controller 1, the controller 1 outputs the signal line.
The electric lock 2 is unlocked by an unlock signal input to the electric lock 2 via 14.

Therefore, the maintenance staff enters the building by using the door of the door of the unlocked building, and performs the work of recovering from the failure of the home elevator.

When the maintenance staff operates the numeric keypad 3 and inputs the personal identification number while the home elevator is in a normal operating state, the electric lock 2 is not unlocked, and the bell 10 is driven by the controller 1 and the bell 10 rings. .

In this way, misuse of the unlocking operation by the maintenance personnel is completely prevented.

As described above, according to the embodiment, at the time of the accident of the home elevator, the maintenance staff of the maintenance company does not have the maintenance staff of the building even if only the users who are trapped in the home elevator are in the building where the home elevator is installed. You can open the door to enter the building and repair the home elevator failure. In this case, the maintenance staff cannot open the door of the building except when a home elevator accident occurs, and abuse of the unlocking operation by the maintenance staff is completely prevented.

Although the numeric keypad is used to input the unlocking signal in FIG. 1, the device according to the present invention is not limited to this, and for example, an ID card may be used.

Further, in FIG. 1, when the home elevator is normal, the bell is rung when the maintenance person unlocks, but the device according to the embodiment of the present invention is not limited to this. For example, a light alarm can be used.

<Effects of the Invention> According to the present invention, at the time of failure of the home elevator, the maintenance staff opens the door of the building even if only the user who is trapped in the home elevator is in the building where the home elevator is installed. You can enter the building and perform repair work for the home elevator failure. Moreover, the unlocking operation of the maintenance staff is invalid except when the home elevator is out of order, and the abuse of the unlocking operation by the maintenance staff is completely prevented.
There are no security issues.
