Abstract

PURPOSE: An apparatus for releasing the double locking of a door is provided to easily open the door by one time of handle operation without switching the double locking apparatus to the release mode inside of the door. CONSTITUTION: An apparatus for releasing the double locking of a door includes an OR gate(21) and an AND gate(22). The OR gate(21) inputs the electronic key signal and metal key signal of the door outside and the operational signal for the lever of the door inside. And, the AND gate(22) controls the output signal of the OR gate(21) in response to the double locking apparatus signal of the door inside or the operational signal for the handle of the door inside.

Description

Double unlocking door {APPARATUS FOR RELEASING DOUBLE LOCKING OF DOOR}

The present invention relates to a technology for releasing the locking function of the double locking device of the door in one-touch operation, and in particular, does not require a separate lock mode release operation, so that the door lock mode is released by one handle operation inside the door. A door lock release device.

FIG. 1 is a conceptual diagram illustrating the operation of a door locking device according to the prior art. As illustrated therein, an electronic key signal (eg, 10 KEY, biometric signal) and a metal key signal outside the door and a lever inside the door An oragate 11 for inputting an operation signal and a handle operation signal inside the door; An AND gate 12 for validating an output signal of the oragate 11 according to the operation of the double locking device inside the door; A dead bolt (13) operated by an output signal of the AND gate (12); An oragate 14 for inputting a handle manipulation signal inside or outside the door; It is composed of a latch bolt (Latch-Bolt) 15 that is operated by the output signal of the ora gate 14, the operation thereof will be described as follows.

Electronic key signals (eg 10 KEY, biometric signal) and metal key signals on the outside of the door, lever operation signals on the inside of the door, handle operation signals on the inside of the door are input through the oragate 11 on the basis of the principle of calculation The input signal of one side of (12) is provided, and the signal of the double locking device is provided as the other input signal of the end gate 12.

Accordingly, when the dual locking device is switched to the release mode, a "high" signal is input to the other input terminal of the AND gate 12, and thus the door input to the AND gate 12 through the OA gate 11. The external electronic key signal or metal key signal or lever operation signal inside the door becomes effective. Therefore, when the user operates the lever inside the door or inputs the electronic key signal or the metal key signal from the outside of the door, the dead bolt 13 is operated to open the door.

On the other hand, the handle operation signal of the inside or outside of the door is input on the principle of the calculation operation through the ora gate 14, the latch bolt 15 is operated by the output signal of the ora gate (14).

When the whole family returns home and the family member does not need to open the door outside the door, the double lock is switched to the lock mode (dead bolt lock function, double lock function). In this state, the "low" signal is input to the other input terminal of the AND gate 12 so that the output signal of the OR gate 11 is invalidated so that the dead bolt 13 cannot be operated as described above. This prevents the door from being opened inside or outside the door. Therefore, illegal intrusion can be prevented more reliably.

In such a state, in order to open the door from inside the door, the handle must be operated after setting the release mode by switching the double locking device.

As described above, in the conventional door lock device, when the door is opened after the double lock device is switched to the lock mode, the double lock device is switched inside the door to set the release mode and then operate the handle twice. Since the process must be carried out if a fire occurs or an urgent situation is developed to go out urgently to give an inconvenience, there was a problem that the damage scale is increased.

Accordingly, an object of the present invention is to provide a door lock releasing device that releases the lock mode and opens the door by one-handed operation inside the door, rather than releasing the lock mode by operating the double lock device separately.

1 is a conceptual view of the operation of the double lock of the door according to the prior art.

Figure 2 is a conceptual view of the operation of the double lock release device of the door according to the present invention.

2 is a conceptual diagram of a double unlocking device of the door according to the present invention, as shown in the electronic key signal (for example, 10 KEY, biometric signal) and the metal key signal outside the door, the lever operation signal inside the door input An oragate 21 for performing; An AND gate 22 for validating an output signal of the oragate 21 according to a dual locking device signal inside the door or a handle operation signal inside the door; A dead bolt 23 operated by the output signal of the AND gate 22; An oragate 24 for inputting a handle manipulation signal inside or outside the door; The latch bolt 25 is operated by the output signal of the oragate 24. The operation of the present invention configured as described above will be described in detail as follows.

Electronic key signal (eg, 10 KEY, biometric signal) and metal key signal on the outside of the door, lever operation signal inside the door are input through the OA gate 21 on the basis of OA calculation principle, and the one side input signal of the AND gate 22. The other input signal of the end gate 22 is provided with an output signal of a double locking device inside the door and a handle manipulation signal inside the door.

Accordingly, when the dual locking device is switched to the release mode, a "high" signal is input to the other input terminal of the AND gate 22, so that the outside of the door input to the AND gate 22 through the OA gate 21 is input. The electronic key signal or the metal key signal or the lever operation signal inside the door becomes effective. Therefore, when the user operates the lever inside the door or inputs the electronic key signal or the metal key signal from the outside of the door, the dead bolt 23 is operated to open the door.

On the other hand, the handle operation signal of the inside or outside of the door is input on the principle of the calculation operation through the ora gate 24, the latch bolt 25 is operated by the output signal of the ora gate (24).

As an example of using the lock mode, when the whole family returns home and the family member does not need to open the door outside the door, the dual lock device is switched to the lock mode. In this state, the "low" signal is input to the other input terminal of the AND gate 22 so that the output signal of the OR gate 21 is invalidated and thus the dead bolt 23 cannot be operated as described above. This makes it impossible to open the door from the outside of the door. Therefore, illegal intrusion can be prevented more reliably.

In this state, when the handle is operated inside the door, the handle manipulation signal corresponding thereto is output as "high" and is supplied to the other input terminal of the end gate 22. Therefore, the door can be opened by one handle operation (one-touch function) inside the door without switching the double lock device to the release mode.

Of course, when the dual locking device is switched to the release mode, a "high" signal is input to the other input terminal of the AND gate 22. Therefore, in this case, regardless of the handle operation signal inside the door, the door can be opened by operating the handle inside the door or inputting the key signal from the outside of the door.

As described in detail above, the present invention allows the dead bolt driving signal to be controlled by the signal of the double locking device inside the door or the handle operation signal inside the door, thereby not switching the double locking device to the release mode inside the door. There is a convenient effect of opening the door with a single handle operation without the need.
