The present invention relates to an electronic door lock, and more particularly, by adding a hook lock structure to the tip of a dead bolt that acts as a locker in the electronic door lock, even though the door is forced to open between the door and the door frame. It relates to a dead bolt locking structure of an electronic door lock characterized by improving the reliability of locking by making it possible to maintain a locked state.

Electronic door locks (or digital door locks) control the mechanical locking mechanism electronically to enhance the intermittence, which is the basic function of the door lock, and are convenient to use, especially since the door is opened by input of fingerprint recognition / password. It has high reliability in that it can prevent the crime of opening the door with a universal key or a replica key in advance.

1 is a Patent Application No. 10-2005-34155, filed April 25, 2005 by the applicant, the electronic door lock described in this patent application as an example to look at the problem of the conventional electronic door lock.

The previously applied door lock includes a main body 1 including a housing case 2 inserted into one side of the door, and each lever handle (not shown in the door) installed inside and outside the door. A ratchet bolt assembly 3 interlocked by the ratchet bolt assembly 3 and a ratchet bolt 4 which is actuated by the ratchet bolt assembly while being pushed outwardly or inwardly of the case 2; The dead bolt assembly 5 and the dead bolt assembly 5 which are installed in the main body 1 and interlocked with the ratchet bolt assembly 3 or operated by a separate key operation and are operated by the dead bolt assembly or outside the case 2 The dead bolt 6 which penetrates inward is provided.

Therefore, when the user turns the lever handle to open the door in the room, the ratchet bolt assembly 3 is operated and the ratchet bolt 4 is introduced into the case 2, and at the same time, the ratchet bolt assembly is dead by the ratchet bolt assembly. The bolt assembly 5 is operated to allow the dead bolt 6 to be introduced into the case.

In this state, when the door is closed and the lever handle is released, the ratchet bolt assembly 3 and the ratchet bolt 4 are repositioned by the elastic force of the spring 3a, which is a part of the ratchet bolt assembly 3, and at the same time, the ratchet bolt assembly As the driving hook 3b, which is a part of (3), pulls the driven hook 5a, which is a part of the dead bolt assembly 5, in the advancing direction, the dead bolt 6 protrudes from the case 2 as a result. Will enter the locking groove 11 formed in the door frame. The dead bolt 6 entered into the locking groove 11 is a state in which the dead bolt is entered into the locking groove unless an allowed signal such as a password is normally input from the outside of the door or a separate key operation is performed. In other words, the locked state cannot be released.

As described above, the conventional door lock has no abnormality in the normal locking function, but in any case, the locking function should not be released. The conventional door lock has a structural loop that can be opened if it is forcibly opened.

That is, when the dead bolt 6 is inserted into the locking groove 11 of the door frame and inserts a tool through the door frame and the door, and then opens the gap between the door frame and the door with a strong force to the locking groove 11. The inserted dead bolt 6 can be separated from the locking groove 11 so that the door can be easily opened.

In view of this, there is a problem that the conventional door lock has a poor reliability because it has a loophole in the locking function. Although the above description is limited to the door lock filed by the present applicant, most door locks often have only dead bolts inserted into the locking grooves, and thus these problems are almost common problems.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the main object of the present invention is to force the door and the hook lock structure to the front portion of the dead bolt, that is, the portion inserted into the locking groove of the door frame Even if the door frame is open, since the hook lock is hung on the end of the locking groove, the dead bolt locking structure of the electronic door lock can prevent the problem of opening the door.

The dead bolt locking structure of the electronic door lock according to the present invention allows the dead bolt to remain locked even when the dead bolt is locked by a tool in the locked state of the dead bolt, and the specific configuration thereof is as follows. .

First, the dead bolt locking structure according to the present invention is divided into two embodiments. The first embodiment consists of a single hook lock, and the second embodiment consists of a pair of hook locks.

First Example

2 is an electronic door lock having a dead bolt locking structure applied thereto according to a first embodiment of the present invention, and FIG. 3 is a configuration diagram of a hook lock according to the first embodiment of the present invention, and FIGS. 4A to 4C. Shows an operational state diagram of the hook lock according to the first embodiment of the present invention.

As described above, the first embodiment according to the present invention is inserted into one side of the door 20, and in front of the upper shed hole 2a-1 to which the dead bolt 6 to be described later is shown and A main body 1 including a housing case 2 having a front panel 2a on which a lower contact hole 2a-2 on which the ratchet bolt 4 is to be mounted is formed; A ratchet bolt assembly 3 interlocked with each lever handle (not shown) installed inside and outside the door 20; A ratchet bolt (4) which is operated by the ratchet bolt assembly and is sunk in or out of the case; A dead bolt assembly (5) installed in the main body (1) and interlocked with the ratchet bolt assembly or operated by a separate key operation; It originates from an electronic door lock having a dead bolt 6 which is actuated by the dead bolt assembly and is in or out of the case 2.

Here, even if the space between the door frame 10 and the door 20 forcibly opened at the front end of the horizontal bar 50 constituting the dead bolt assembly 5, a single door to maintain the locked state of the door frame and the door It is a feature of the first embodiment that the hook lock 100 is installed.

The hook lock 100 is pivotally coupled to the front end of the horizontal bar (50) pin (p), the front end of the hook lock 100 in accordance with the rotation direction of the hook lock locking plate 12 of the door frame (10) The hook hook 110 is selectively provided on the inner side.

In addition, the hook lock 100 is caught by the inner end of the upper haunting hole (2a-1) in accordance with the forward operation of the hook lock to the rear of the hook hook 110, the locking hook 110 is the locking plate 11 Equipped with a locking projection 120 to induce rotation to be caught on the inner side of the).

In addition, when the locking hook is caught between the locking hook 110 and the locking protrusion 120 by the end of the upper mounting hole (2a-1) when the locking hook is caught by the locking hook to the locking plate. A pressing section 130 is provided to keep the jammed state.

Meanwhile, the hook lock 100 overlaps a plurality of thin plates 101 and combines the overlapping thin plates 101 by a piece 102. The reason why the hook lock is formed by overlapping a plurality of thin plates 101 is as follows. This is because of the advantage of freely adjusting the thickness of the hook lock according to the number of overlap of the sheet.

In addition, an elastic member (for example, a coil spring) 140 is installed on the horizontal bar 50 to elastically support the hook lock 100 in a rotating direction, and is installed or formed on the horizontal bar 50. A stopper 150 for limiting the rotation angle of the hook lock 100 is installed.

The operation of the hook lock 100 of the first embodiment according to the present invention having the above configuration is as follows.

As shown in the drawing, the state before the locking is the state where the dead drone 5b is guided at about five o'clock, and when the dead drove 5b is rotated clockwise in the drawing, the horizontal bar 50 is connected thereto. Is horizontally moved to the left in the drawing. Accordingly, the hook lock 100, which is rotatably installed at the front end of the horizontal bar 50, is also moved to the left side along with the horizontal bar 50.

In this way, the hook lock 100 does not completely pass through the upper haunting hole 2a-1 of the front panel 2a while the hook lock 100 is moved to the left side, but only the hook hook 110 passes. It is in the state entered into the locking groove 11 of the door frame (10). The portion after the hook hook 110 does not pass through the upper haunting hole 2a-1, and the hook protrusion 100 is caught from the point as the catching protrusion 120 is caught by the upper haunting hole 2a-1. Is rotated clockwise in the drawing about the pin (p), and the hook hook 110 provided at the tip of the hook lock is rotated about 90 ° by the clockwise rotation of the hook lock. It will be locked to the inner surface, that is, locked state.

In addition, since the pressing portion 130 of the hook lock 100 is pressed at the end of the upper inlet hole 2a-1, the locking plate 12 even though the door frame 10 and the door 20 are forcibly opened. It is impossible to forcibly remove the hook lock from the locking groove before the end of the) or the hook lock 100 is broken, thereby increasing the reliability of the locking.

On the contrary, when releasing the lock, if the dead lever 5b is rotated counterclockwise in the drawing, the hook hook 100 of the hook lock 100 is caught by the end of the locking hole 12a of the locking plate 12, and the hook lock is engaged. 100 is rotated counterclockwise in the drawing, when the stop is stopped by the stopper 150, the locking hook 110 is released, that is, the locking is released.

2nd Example

5 is an electronic door lock having a dead bolt locking structure applied thereto according to a second embodiment of the present invention, and FIG. 6 is a configuration diagram of a hook lock according to a second embodiment of the present invention, and FIGS. 7A to 7C. Shows an operational state diagram of the hook lock according to the second embodiment of the present invention.

As shown in the drawings, the second embodiment according to the present invention is similar to the first embodiment, but the first hook lock 210 and the second hook lock 220 to face the hook lock 200 to each other. It is made up. The hook hooks 210 and 220 are formed with hook hooks 211 and 221, hook protrusions 212 and 222, and pressing parts 213 and 223, respectively, as in the first embodiment. Between the two hook locks 220, each hook through the elastic member 230 for elastically supporting in the direction of movement (rotational direction), the corresponding of the first hook lock 210 and the second hook lock 220 Forming grooves (214, 224) for mounting the upper, lower ends of the elastic member 230 on the surface.

In addition, a common stopper 240 is installed on the horizontal bar 50 between the first and second hook locks 210 and 220 to limit the rotation angles of the first and second hook locks.

Meanwhile, the first and second hook locks 210 and 220 overlap the plurality of thin plates 201 and combine the overlapping thin plates 201 by a piece to integrate them. The reason why the hook lock is configured by stacking a plurality of thin plates is that the thickness of the hook lock can be freely adjusted according to the number of overlap of the thin plates.

Since the operation of the hook lock 200 of the second embodiment according to the present invention having the above configuration is the same as the first embodiment, a detailed description thereof will be omitted. However, since the first and second hook locks 210 and 220 facing each other operate in the corresponding direction, the hook lock 200 of the second embodiment is locked more securely than the first embodiment because the hook locks 200 and 220 are operated in corresponding directions. This has the advantage that it is possible.

As described above, the present invention can prevent the door from being opened by hooking the hook lock at the end of the locking groove even if the hook lock is added to the portion inserted into the locking groove of the door frame to force the door and the door frame apart. The reliability of the door lock can be improved.
