Abstract

PURPOSE:To improve usability by providing delay automatic lock mode function for locking automatically upon the lapse of the specified time after closing a door so as to enable an inhabitant to open the door immediately to enter the house again in the case of having left something behind or the like. CONSTITUTION:When the inhabitant of each house goes out and closes the door, for instance, a controller A outputs a lock signal to an electric lock E after the lapse of the specified time, and a dead bolt E1 advances to lock. Upon coming home from a visit, the inhabitant presses a push button switch S. Then the controller A outputs a lock release signal to the electric lock E and lights a lock release display part S1. In this case, the specified time of placing the door in the lock released state after closing the door can be set optionally on the user side. The controller A can be also used as a code number input device so as to enable locking and lock releasing through a separate control device. Accordingly, even at the time of using an automatic lock function device, the lock released state is kept within the specified time so as to enable the inhabitant to open the door D as occasion demands and to enter the house again.

And an electric locker E attached to a door D, and an operating device A installed at an outdoor entrance. Power transformer F
Is for converting a commercial power supply into a predetermined voltage and supplying power to the operating device A, and is connected to the operating device A via an electric line. The push button switch S is installed at the indoor entrance,
The switch is connected to a switch connection portion (not shown) of the operation device A through an electric line, and the contact is closed once each time the button is pressed. Further, the push button switch S is provided with a red unlock display section S ₁ and a green lock display section S ₂ which are lit as will be described later. The electric lock E is provided with a dead bolt E ₁ which advances and retreats according to a signal from the operation device A, and is connected to an electric lock connection portion (not shown) of the operation device A via an electric line. When the deadbolt E ₁ is advanced by the lock signal from the operation device A, the deadbolt E ₁ is fitted into a bolt receiver (not shown) provided on the outer frame (not shown) of the door D, and the door is closed. D
It is designed so that the door cannot be opened. When the deadbolt E ₁ is retracted by the unlocking signal from the operation device A, the deadbolt E ₁ is pulled out from the bolt receiver (not shown) provided in the outer frame (not shown) of the door D, The door D can be opened.

By the way, the operation device A has operation keys A _1, ... A ₁₂
Is provided, and an arbitrary personal identification number is set in each dwelling unit, and when the personal identification number is input from the operation keys A _1, ... A ₁₂ , the operation unit A outputs an unlocking signal to the electric lock E. .. Therefore, the resident of each dwelling unit who has returned from the place where he / she is to unlock the electric lock E by opening the door D by inputting the personal identification number with the operation keys A _1, ... A ₁₂ of the operating device A. You can enter the dwelling unit.

When the push button switch S is pressed, the operating device A outputs an unlocking signal to the electric lock E if the electric lock E is in a locked state (a state in which the dead bolt E ₁ is advanced), If the electric lock E is in the unlocked state (the state where the dead bolt E ₁ is retracted), a lock signal is output to the electric lock E. Further, the operating device A has a function of displaying the locked / unlocked state of the electric lock E on the unlocked display portion S ₁ and the locked display portion S ₂ of the push button switch S. In the locked state, the unlocking display portion S ₁ of the push button switch S is turned on, and when the electric lock E is in the locked state, the locking display portion S ₁ of the push button switch S is turned on.

Although not shown, the electric lock E is provided with a means (the limit switch) for detecting the forward and backward state deadbolt E _1, and means for detecting the advancing and retracting state of the dead bolt E ₁ operating device A and Are connected by electric lines.

Therefore, if the occupant of each dwelling unit goes out and the lock display portion S ₂ of the push button switch S is lit, the resident pushes the push button switch S. Then, the electric lock E is unlocked and the unlock display portion S _{1 of the} push button switch S is turned on. Here, the resident opens the door D, exits the dwelling unit, and closes it again. After that, the resident presses the operation key A ₁₁ (locking key) of the operation device A to lock the electric lock E.

However, since it is troublesome to press the operation key A ₁₁ (locking key) of the operating device A to lock the electric lock E every time a resident of each dwelling unit goes out, the operating device A has an automatic locking mode function. The operating device A
Can be set to the automatic locking mode. When this automatic lock mode function is used, the operating device A operates as follows.

That is, if the occupant of each dwelling unit goes out and the lock display section S ₂ of the push button switch S is lit, the resident pushes the push button switch S. Then, the actuator A is the electric lock E
An unlocking signal is output to the electric lock E in the unlocked state, and the operating device A lights the unlocking display portion S ₁ of the push button switch S. This time is the time t ₁ in FIG. Here, the resident opens the door D. This time is the time t ₂ in FIG. And
The resident goes out of the unit and closes again. This point is t in FIG.
_{There are three} points. Then, the operating device A immediately outputs a lock signal to the electric lock E. Then, the electric lock E becomes the dead bolt E.
_It advances to ₁ and becomes locked. Of course, even when the electric lock E is locked by the automatic lock mode function, the lock display section S ₂ of the push button switch S is turned on. Therefore, when the automatic locking mode function is used, when the resident of each dwelling unit goes out, the resident opens the door D, goes out of the dwelling unit, and closes again.
Then, even if the operation key A ₁₁ (locking key) of the operation device A is not pressed, the lock is automatically performed. Therefore, it can be said that the use of the automatic lock mode function will prevent forgetting to lock.

When the automatic lock mode function is used, a means (limit switch etc.) for detecting the opening / closing of the door D is required separately, and the door D is opened / closed. A means for detecting a door (a limit switch or the like) is connected to the operating device A via an electric line.

[0010]

However, even with such an automatic locking mode function, for example, when the resident intends to go out, the door D is opened, and the door D is opened outside and the door is closed again.
When the user forgets what he / she has forgotten, the electric lock E is already in the locked state, so the operation keys A _1, ... A ₁₂ of the operation device A are operated one by one to input the personal identification number and lock the electric lock E. There was a problem that it had to be unlocked, which was annoying.

The present invention has been made to solve the above problems, and its purpose is to open the door, go out of the dwelling unit again even if the automatic locking mode function is used. You can easily open the door shortly after closing it,
It is to provide a user-friendly electric lock device.
