The present invention relates to an electronic opening and closing door lock that can be installed and used in the entrance doors of apartments, offices, etc. In particular, the stability is good, the open and closed state can be accurately identified in the room, and the identity of the visitor is displayed according to the preference of the consumer. It can also be used in conjunction with the existing home automation system (video interphone device) that can be checked.

The conventional electronic door lock has only a function of simply opening the locked door lock after confirming the visitor's identity with an interphone, which is extremely simple in use, and can be arbitrarily opened as a substitute for a key from the outside of the door. This was a relatively weak disadvantage.

As domestic prior arts related to such door locks, Korean Utility Model Publication No. 93-1873 and Japanese Utility Model Publication No. 54-168291 have been disclosed, but such prior art does not overcome the following disadvantages. . Looking at it; Korean Utility Model Publication No. 93-1873 relates to a door lock named as a double system double bar lock, and its technical gist is that the door lock can be unlocked by inputting a key which is mechanical and electronic. The technical idea is that the door lock can be unlocked by inputting the mechanical and electronic key in more detail. After inserting the disk card for power supply, each of the input keys for opening the two dead bolts is opened. In order to open the door only when the input is made in the first and second rounds, the anti-theft function of the door lock is strengthened.In addition, in the event of an electrical system failure, the mechanical open operation can be performed separately to enhance the convenience of use. It uses solar energy driving means to supply power without external power. As this technology is unexpectedly being stolen by an input key, it cannot be considered that the anti-theft function is performed perfectly, and it is not possible to remotely open the door lock and use it for a special place of use (for example, a computer room). However, it can only be used only in places that require confidentiality, etc., which should not be output by outsiders.

In addition, since the door lock is exposed to the outside of the door, the possibility of being damaged by external force cannot be ignored, so the stability was insignificant.

In addition, Japanese Laid-Open Utility Model Publication No. 54-168291 discloses a configuration in which the open door can be selectively opened by starting a small drive motor that interlocks a debol bolt of the door lock with a timer, but it is compatible with existing doors. In addition to the problems that can not be a failure rate due to the overload of the motor is likely to occur, and the door lock is attached to the door itself as a way that the wiring line is damaged when opening and closing the door was also very high.

Accordingly, the present invention provides an electronic door lock that is fundamentally different from the existing door lock as described above. The door lock body is installed on a door frame (= door frame) in which the door is hinged, and a strike box is provided. By combining with the door, the door lock can more effectively perform the prevention function from theft and at the same time, it provides a means for simultaneous mechanical opening and electronic opening, and can be opened and closed by wire. In order to provide more convenience to the user, and to provide a versatility of the intended use, the specific embodiments of the present invention will be described in detail with reference to the accompanying drawings below.

The door lock of the present invention is largely divided into the mechanical configuration of the locking device for opening and closing the door and the circuit configuration of the power supply and display device.

First, the mechanical configuration of the locking device will be described with reference to FIG. A rectangular lock chain (1) is fixed to the door frame by attachment means such as a bolt (20), and the door (2) for entering and exiting the inlet chamber (3) opened on the upper side of the lock chain (1) It is fixed by this bolt 20 etc.

As shown in FIG. 2, a pivoting disc 4 extending slightly to the lower side of the urinary tongue 3 is constructed by the pin shaft 9, and an upper side of the pivoting disc 4 is provided with a clamping request. 5) is contemplated, the lower groove side groove 10 is formed in the inclined shape is configured so that the lock plate 13 built on the pin shaft 14 in the lower locking jaw (11) thereof can be locked and separated.

And the outer side of the lock plate 13, the handle 15 is protruding so that the handle 15 is slightly exposed to the long side hole 19 of the chain barrel (10) to allow the user to lift and operate the lock pin 13 by hand. It is configured to be able to select the locked state and the unlocked state of the rotating plate (4).

An electromagnet 126 is accommodated in the lower chain orthodontic cylinder 1 of the lock pin 13 so that the retaining pin 17 is elastically installed upward on the spring 17 'and drilled on the upper side of the excitation pin 17. Between the one shaft hole 17 ″ and the long hole 13 ′ laid on the lower side of the lock pin 13, the connecting pin 18 is hypothesized in a flow state so that the connecting pin 18 at the time of excitation of the electromagnet 16 is opened. 13 ') in turn in both directions (AB) to allow the lock pin 13 to lock and unlock the pivoting plate 4, and to lock and unlock the pivoting plate 4 and the lock pin 13 The locking state is displayed on a separate display lamp.

In addition, the clasp (1) is installed in the door frame of the door and the door side is formed by a separate body of the catch (2) to be indented in the concave chamber 3 of the clasp (1) as shown in FIG. It is fixed by the attachment means, such that the locking jaw (6) formed inside the locking jaw (6) to be locked and separated from the locking request (5) of the pivoting plate (4) of the locking barrel (1) And a lock 8 that can be opened and closed outdoors on the upper side of the catching cylinder 2, and the lock pin 7 is raised and raised upward from the inner side, so that the concave chamber 3 of the clasp holder 1 ) It is configured to be caught and disengaged on the upper side

The circuit portion of the power supply and display device for driving the electromagnet 16 and the limit switches SW1 and SW2 accommodated in the mechanical drive device is shown in FIG.

In other words, the power supplied is an electronic current supply circuit (B), instantaneous current supply stability circuit (C), locking status display circuit (D), a method sensor circuit to a constant voltage circuit (A) stably supplied with AC 12-15V power supply. (E) A series of circuits are connected.

In the door lock of the present invention, which can be configured as described above, the operation and effects of the components are described in more detail below.

As shown in FIG. 3, the locking container 1 is fixed to the door frame of the door and the locking container 2 is fixed inward to the corresponding part of the door so that the locking container 3 of the locking container 1 of the locking container 1 is closed when the door is closed. (2) is inserted into the locking jaw (6) is a locking and disengagement operation to the locking request (5) of the rotary disk (4) is slightly raised in the urine chamber (3), (a) As shown, the inner end of the lock pin 13 is supported on the engaging jaw 11 side of the recessed groove 10 of the pivoting disk 4, that is, the handle 15 is lowered to the lower side of the long hole 19. Since the rotating disk 4 cannot rotate integrally about the pin shaft 9, this state is because the locking jaw 6 of the locking container 2 is caught in the locking request 5, and thus the separation of the rotating disk 4 is not allowed. The door will remain locked.

In this state, when the lock pin 13 is operated in the room by raising the handle 15 upward, as shown in FIG. 2 (b), the inner end of the lock pin 13 is rotated about the pin shaft 14. Since the fixed state by the locking step 11 is released from the recess groove (10) of the release of the locking door (2) is easily separated from the recess chamber (3).

At this time, the locking request (5) of the rotating plate (4) is dragged by the locking jaw (6) of the locking container (2) is rotated at an angle of about 45 ° to prepare for closing the door, this state is the lock pin (13) Hook 13 ″ lightly supports the locking step 11 to help the locking request 5 of the pivoting plate 4 always maintain a constant position.

The description of the above-described operation and effect may be referred to as the case where the lock pin 13 is manually driven, and has a safety function capable of arbitrarily locking and unlocking the lock device in the case of power failure.

Referring to the operation and effect when the device of the present invention is driven remotely by the electric circuit as follows.

When power is supplied to the electromagnet 16 by the power supply circuit of FIG. 4, the electromagnet 16 is instantaneously operated for a predetermined time by the instantaneous current supply stabilization circuit C. The excitation pin 17 is pulled and released. You will repeat the action.

If the door is closed as shown in FIG. 2 (a) and the lock pin 13 is set on the locking jaw 11 of the pivoting plate 4 as a default, the electromagnet 16 has the excitation pin 17 It is raised upward by the spring 17 ', and the connection pin 18 keeps being stopped in the A position of the recessed groove 10 at the lock pin 13 side.

In this state, when the switch of the driving circuit is pressed to open the door, the electromagnet 16 is momentarily operated, and the excitation pin 17 is lowered to pull the connecting pin 18 downward, thereby connecting the pin 18 to the long hole ( 13 '), the lock pin 13 is pulled down at the A position and the lock pin 13 is rotated about the pin shaft 14 from the state of (a) to the state of (b).

Once the rotation is completed, the excitation pin 17 is raised upward by the restoring force of the spring 17 '. At this time, the connecting pin 18 is switched to the B position of the long hole 13' because the bearing state is fluid. While keeping the pivot pin lock pin 13 in the displaced position, it is ready for the next operation.

In this way, when the lock pin 13 is switched from the position of (a) to the position of (b), the locked door is switched to the open state.

When the door is closed again after the entrance and exit, the pivoting plate 4 returns to the position of (a). At this time, when the door is locked again, the drive pin of the electromagnet 16 is connected to the excitation pin 17. The connecting pin 18 is lowered again at the position of the long hole 13'B in FIG. 2 (b) so that the lock pin 13 is caught by the locking jaw 11 of the pivoting plate 4 (a Return to the position of) to maintain the locked state of the door.

Therefore, the locked state and the unlocked state of the door can be accurately driven remotely in the room without the user going directly to the entrance.

In addition, a switching switch SW1 is installed at the lower side of the pivoting plate 4 so that the connecting pin 12 'switches the switch SW1 every time the rotation of the pivoting disk 4 is rotated so that the door is opened or closed. LED of Fig. 4), and also when the manual lock pin 13 is driven, the lower switching switch SW2 is operated so that the locking and unlocking state of the lock pin 13 is displayed indoors, and the door is remotely inquired. Opening and closing of the locking device is confirmed correctly.

The present invention can be installed as a separate device, such as a general house or apartment, or can be installed in a merger with an existing home autonomous system.

If there is no person indoors, when locking the door from the outside, rotate the lock (8) of the locking container (2) from the outside of the door, and the inner lifting lock pin (7) will be required. Locked in the upper part of the room (3) will be able to lock the door firmly and securely when going out.

The door lock of the present invention can not be opened arbitrarily from the outside once the locking state is switched to the locked state from the inside, and the opening and closing state of the front door and the lock pin 13 is displayed remotely to prevent the intruder from inadvertent inadvertence. In addition, it can be used as an electronic switch type and a manual type, and can be used not only in preparation for power failure, but also in common at the entrance side and living room side, which can further increase the convenience of use.

In addition, since the use voltage is about 12V DC, there is no risk of electric shock or short circuit, and the electric circuit is installed in the door frame and built into the chain tube (1), so it is easy to wire and there is no risk of damaging the wiring even when opening and closing the door.
