The present invention relates to a mortise lock device, and more specifically, it is slim and compact, and is very easy to install, and minimizes mechanical frictional contact, so that the failure rate is reduced, the life is extended, and the electronic control is possible. A mortise lock device employable in a door lock.

The mortise lock device is a locking device incorporated in a door, and includes a housing, a dead bolt and a latch bolt capable of coming in and out of the housing, and a lever device for operating the dead bolt in response to manipulation of a key or a handle.

In particular, the dead bolt is locked to the door frame while protruding from the side of the housing. Therefore, the door is locked. The key and the handle are inserted into the housing and released from the door frame. Thus, the door is released.

However, such a conventional mortise lock device has a disadvantage in that it is very difficult to be incorporated in a door due to its large size and complicated internal structure. In particular, in recent years, a lot of slimmer doors have been gradually manufactured, and it is very difficult to be incorporated into a slimmer door with a large-scale conventional mortise lock device. Therefore, the size of the mortise lock device must be made slim and compact in accordance with the slimmer door.

In addition, the conventional mortise lock device has a disadvantage in that it is difficult to employ a digital door lock that is electronically controlled because the dead bolt and the latch bolt are operated by a mechanical operation when the key and the handle are operated.

That is, the recent door lock is a digital method of controlling a dead bolt by pressing a key input button provided on the outside of the door or by using a safety key in which a semiconductor chip is embedded. Therefore, there is a problem that it is difficult to adopt a digital door lock with a conventional mortise lock device that is mechanically operated.

In addition, the conventional mortise lock device is a mechanical structure driven by mechanical frictional contact, and thus, when excessive force is applied to the key or the handle, the frictional contact portions of the various levers are damaged or broken. There is a problem of frequent and short lifespan.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide a mortise lock apparatus which is very easy to install by having a slim and compact structure.

Another object of the present invention is to provide a mortise lock device that can be employed in a digital door lock by enabling electronic control.

Still another object of the present invention is to provide a mortise lock device having a simple structure and minimizing mechanical operation by improving an internal structure.

Still another object of the present invention is to provide a mortise lock device having a simple structure and minimizing mechanical operation, thereby preventing frequent failures caused by mechanical operation, and thus extending the life of the device.

In order to achieve the above object, the mortise lock device of the present invention, the housing is built in the door; The door frame is locked to the door frame while elastically returning from the release position inside the housing to the outside locking position, and when the opened door is closed, the door frame is contacted with the door frame so as to be pushed by the door frame to move to the release position. Dead bolt and one side is inclined; Fixing means for fixing the dead bolt returned to the locking position; When rotating the inner handle inside the door, the dead bolt fixed to the locking position is released and at the same time the rotational force of the inner handle is transmitted to the dead bolt to move the dead bolt from the locking position to the release position. Release / delivering means; When an authentication signal is input from the outside of the door, the inner handle is rotated by the outer handle outside the door to release the dead bolt fixed to the locking position and simultaneously move the dead bolt of the locking position to the release position. Connecting means for integrally connecting the outer handle and the inner side handle so as to be made; Release / allow means for releasing the dead bolt fixed to the locking position when the door is opened, and allowing the fixing means to fix the dead bolt returned to the locking position when the door is closed. It is characterized by including.

Hereinafter, a preferred embodiment of the mortise lock device according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing the configuration of a mortise lock device according to the present invention, Figure 2 is a cross-sectional view taken along the line II-II of Figure 1, Figure 3 is a cross-sectional view taken along the line III-III of FIG.

1 to 3, the mortise lock device of the present invention includes a housing 10. The housing 10 is built in the door D, and an operating chamber 12 is formed therein.

On the other hand, the operating chamber 12 of the housing 10 has a first rotating member 20 connected to the central axis of rotation 14a of the outer handle 14, the central axis of rotation 16a of the inner handle 16 and It is provided with a second rotating member 30 connected.

The first rotating member 20 has coupling holes 22 formed on both sides of the shaft center, and the coupling holes 22 have a pair of coupling fingers formed on the rotation center shaft 14a of the outer handle 14. 14b are respectively joined. Therefore, the first rotating member 20 is integrally connected with the rotation center shaft 14a of the outer handle 14.

Since the first rotating member 20 is integrally connected to the rotational center shaft 14a of the outer handle 14, the first rotating member 20 is integrally rotated when the outer handle 14 is rotated.

The second rotating member 30 has a coupling hole 32 formed in the center of the shaft, and the rotation center shaft 16a of the inner handle 16 is fitted into the coupling tool 32. Therefore, the second rotating member 30 is integrally connected with the rotation center shaft 16a of the inner handle 16.

Since the second rotation member 30 is integrally connected with the rotational center shaft 16a of the inner handle 16, the second rotation member 30 is rotated integrally when the inner handle 16 is rotated.

Here, the second rotating member 30 is formed with a pair of through holes 33 which are aligned with the engaging holes 22 of the first rotating member 20, and the through holes 33 are formed of a second through member 33. The coupling fingers 14b of the outer handle 14 penetrating the coupling holes 22 of the one rotating member 20 are configured to be fitted.

The through hole 33 is configured in the form of a slot as shown in FIG. 1 so as not to interfere with the coupling finger 14b that rotates together with the outer handle 14. Thus, the slotted through hole 33 does not prevent the rotation of the outer handle 14. In particular, since it does not interfere with the rotation of the outer handle 14, the outer handle 14 and the inner handle 16 can be rotated independently of each other.

Referring again to FIGS. 1 to 3, the mortise lock device of the present invention includes a dead bolt 40 installed in the operating chamber 12 of the housing 10.

Dead bolt 40 is installed so as to move between the locking position (A1) and the release position (A2) of the outer side of the housing 10, and is locked to the door frame (D1) in the locking position (A1), release It is released from the door frame D1 at the position A2.

On the other hand, the dead bolt 40 is always elastically pressed in the direction of the locking position A1 by the spring 42. Therefore, it always returns to the locking position A1 unless an external force is applied.

Since the dead bolt 40 is always returned to the locking position A1, the dead bolt 40 may be caught by the door frame D1 while the open door D is closed. Therefore, one side portion 40a of the dead bolt 40 in contact with the door frame D1 when the door D is closed is inclined to be inserted inward while being pressed by the door frame D1. The bolt 40 allows the door D to be closed despite the door frame D1 being engaged.

And, referring to Figure 1, the mortise lock device of the present invention further comprises a fixing means for fixing the dead bolt 40 returned to the locking position (A1).

The fixing means has a blocking lever 50 rotatably installed in the operating chamber 12 of the housing 10.

The blocking lever 50 rotates between the blocking position C1 and the release position C2, and has the blocking finger 52. As shown in FIG.

The blocking finger 52 supports the back of the dead bolt 40 at the locking position A1 at the blocking position C1. Therefore, the dead bolt 40 to be retracted from the locking position A1 to the release position A2 is restricted. In particular, by limiting the retraction of the dead bolt 40, the dead bolt 40 can be fixed in the locking position A1.

The blocking lever 50 fixes the dead bolt 40 to the locking position A1, thereby preventing an external unauthorized intruder from manipulating the dead bolt 40 to unlock the door D without permission. .

On the other hand, the blocking lever 50 is elastically pressurized by the spring 54 in the blocking position C1 direction. Therefore, the blocking lever 50 tries to limit the retreat of the dead bolt 40 while automatically moving to the blocking position C1 when the dead bolt 40 returns to the locking position A1.

Referring back to FIG. 1, the mortise lock device of the present invention, when rotating the inner handle 16, presses the blocking lever 50 to the release position C2 and is fixed to the locking position A1. It releases the bolt 40, and at the same time has a release / transfer means for transmitting the operating force of the inner handle 16 to the dead bolt (40).

The release means may include the second rotating member 30 and the second rotating member 30 installed on the center of rotation shaft 16a of the inner handle 16 and the blocking lever 50 in the release position C2. It consists of the 1st push piece 34 formed in the 30.

In particular, when the first push piece 34 rotates the inner handle 16, the first lever 34 releases the blocking lever 50 from the blocking position C1 while rotating with the second rotating member 30. Pressurize with). Thus, the blocking lever 50 allows the dead bolt 40 to retreat and, as a result, to release the dead bolt 40 from being fixed.

The transmission means includes a second push piece 35 installed on the second rotating member 30. When the second push piece 35 rotates the inner handle 16, the second push piece 35 interferes with the dead bolt 40. Therefore, the operating force of the inner handle 16 is transmitted to the dead bolt (40).

According to this transmission means, since the operating force of the inner handle 16 is transmitted to the dead bolt 40, the dead bolt 40 to which the operating force is transmitted moves from the locking position A1 to the release position A2 while the door D ) Can be released.

On the other hand, at the time of the rotation operation of the inner handle 16, the time when the first push piece 34 presses the blocking lever 50 rather than the time when the second push piece 35 presses the dead bolt 40 is predetermined. The time difference should be fast.

This is because the first push piece 34 must first press the blocking lever 50 to the release position C2 to release the dead bolt 40 from the first push piece 34 to release the dead bolt 40. This is because the pressure can be pushed in the release position A2.

1 and 2 again, the mortise lock device of the present invention releases the dead bolt 40 by pressing the blocking lever 50 to the release position C2 when the door D is opened. And, when the door (D) is closed, it is provided with a release / allow means for allowing the movement of the blocking lever 50 to rotate to the blocking position (C1) to fix the dead bolt (40).

The release / allowing means includes a push lever 60 moving between the protruding position E1 outside the housing 10 and the push position E2 inside the housing 10, and the push lever 60 protruding from the protruding position E1. It is composed of a spring 62 which is elastically pressed in the () direction.

In particular, the pressing lever 60 presses the blocking lever 50 to the release position C2 while the door D moves to the protruding position E1 outside the housing 10 as the door D is opened. Thus, the blocking lever 50 can release the dead bolts 40 from being fixed and, as a result, allow the dead bolts 40 to retract when the door D is opened.

And the pressing lever 60 is moved to the pressing position (E2) while being pressed by the door frame (D1) as the door (D) closes, the pressing lever (60) moved to the pressing position (E2) is a blocking lever ( Release the pressure of 50). Therefore, the blocking lever 50 which allows the movement of the blocking lever 50 to rotate to the blocking position C1, and as a result, the blocking lever 50 which moved to the blocking position C1 at the time of closing of the door D is dead bolt 40. FIG. It is possible to limit the retreat of). As a result, the door D is fixed when the door D is closed, and the forced release of the door D is blocked by the door D.

Here, the pressing finger 55 is formed integrally with the blocking lever 50. The pressing finger 55 rotates while being pressed by the pressing lever 60 moving in the protruding position E1. Therefore, the blocking lever 50 is pressed to the release position C2.

On the other hand, the spring 62 for elastically pressing the pressing lever 60 in the protruding position E1 direction should have a greater tension than the spring 54 for elastically pressing the blocking lever 50 to the blocking position C1.

This is because the spring 62 of the pressing lever 60 must have a greater tension than the spring 54 of the blocking lever 50, so that when the door D is opened, the spring 54 of the blocking lever 50 is opened. This is because the pressing lever 60 can be pushed to the release position C2 while being pressed.

Referring back to Figures 1 and 2, the mortis lock device of the present invention, when the user outside the door (D) input the authentication signal using a button or a safety key, the outer handle 14 and the inner handle 16 ) Is connected to each other.

The connecting means includes a first rotating member 20 installed on the central shaft 14a of the outer handle 14 and a central shaft 16a of the inner handle 16 and having a coupling groove 30a. It is installed in the first rotating member 20 so as to correspond to the second rotating member 30 and the coupling groove (30a) and is fitted into the coupling groove (30a) while moving from the release position (F1) to the coupling position (F2) Coupling pin 70, the spring 72 for elastically pressing the coupling pin 70 in the release position (F1) direction, and press the coupling pin 70 in the coupling position (F2) direction as the authentication signal is input. It is provided with a pressing means (80).

Since the coupling pin 70 is fitted into the coupling groove 30a while moving to the coupling position F2, the coupling pin 70 integrates the first rotation member 20 and the second rotation member 30. Therefore, the outer handle 14 connected to the first rotating member 20 and the inner handle 16 connected to the second rotating member 30 are integrated.

Since the coupling pin 70 connects the outer handle 14 and the inner handle 16 integrally, when the outer handle 14 is rotated, the inner handle 16 also rotates at the same time, and the inner handle 16 is rotated. As it rotates, the blocking lever 50 can move to the release position C2, and the dead bolt 40 can move to the release position A2. Thus, the door D is released.

Since the spring 72 elastically presses the coupling pin 70 in the release position F1, the coupling pin 70 is disposed at the release position F1 unless an external force is applied. Therefore, the outer handle 14 and the inner handle 16 are separated from each other unless an external force is applied.

The pressurizing means 80 includes a driving means 81 driven as the authentication signal is input, an actuating plate 82 moving from the preparation position G1 to the operating position G2 by the driving means 81, It is provided with a pressing member 84 for pressing the coupling pin 70 toward the coupling position (F2) while being pressed by the operating plate 82 to move from the ready position (G1) to the operating position (G2).

In particular, the pressing member 84, by pressing the coupling pin 70 in the coupling position (F2) direction, so that the coupling pin 70 can be coupled to the coupling groove (30a), the coupling pin 70 is coupled By allowing the coupling to the groove 30a, the outer handle 14 and the inner handle 16 are integrated. Accordingly, when the outer handle 14 is rotated, the inner handle 16 may also be rotated at the same time to release the door D.

Here, the pressing surface 84a of the pressing member 84 forms an arcuate curved surface along a concentric circle centered on the rotation center shafts 14a and 16a of the inner / outer handles 14 and 16. This is to continuously press even when the coupling pin 70 coupled to the coupling groove 30a is rotated together with the outer handle 14, and thus, the outer handle 14 when the outer handle 14 is rotated. ) And the inner handle 16 can be continuously connected.

And the pressing member 84 is operatively connected with the operation plate 82 by the exercise transmission means.

The movement transmitting means may be pressed upwards as the pressing protrusions 85 formed on the operating plate 82 and the pressing protrusion 85 move together with the operating plate 82 to the right operating position G2. Pressing so that the first inclined surface 86 formed on the pressing member 84 and the pressing projection 85 together with the operation plate 82 to the left to the ready position (G1) as it moves to the downward direction The second inclined surface 87 formed on the member 84 is provided.

According to the pressurizing means 80 of such a configuration, since the outer handle 14 and the inner handle 16 are integrally connected as the authentication signal is input, the inner handle 16 is connected through the outer handle 14. The door D while releasing the blocking lever 50 and the dead bolt 40 through the outer handle 14 by allowing the operation and operating the inner handle 16 through the outer handle 14. To let go.

On the other hand, the driving means 81 of the pressing means 80, along the rotating shaft 81a, the screw shaft 81b which is integrally installed on the output shaft of the rotating motor 81a, along the rotating screw shaft 81b. It consists of a nut (81c) is fixed to the operation plate 82 to screw. In particular, the nut 81c moves the operation plate 82 from the ready position G1 to the operating position G2 while screwing along the screw shaft 81b.

As a modification of the drive means 81, it may be composed of a solenoid (not shown). The solenoid is operated according to the applied power to move the operation plate 82 from the ready position (G1) to the operating position (G2).

Next, an operation example of the present invention having such a configuration will be described with reference to FIGS. 4 to 8.

First, a case in which the door D is to be released by using a button or a safety key from the outside of the door D will be described.

Referring to FIG. 4, a user outside the door D inputs an authentication signal using a button or a safety key.

Then, the driving means 81 is operated, and as the driving means 81 is operated, the operation plate 82 moves from the ready position G1 to the operating position G2. And as the operation plate 82 moves from the ready position (G1) to the operating position (G2), the pressing member 84 also starts to press the coupling pin 70 in the direction of the engagement position (F2) while pressing.

At this time, the coupling pin 70 is coupled to the coupling groove 30a of the first rotating member 20 while pressing in the coupling position F2 direction. Therefore, the outer handle 14 and the inner handle 16 are integrally connected.

In this state, as shown in FIG. 5, the user outside the door D rotates the outer handle 14. Then, the inner handle 16 connected to the outer handle 14 rotates.

As the inner handle 16 rotates, the second rotating member 30 simultaneously rotates to press the blocking lever 50 and the dead bolt 40 to the release position C2 and the release position A2, respectively. Therefore, the door D is unlocked and is in an openable state.

Next, a case in which the door D is kept open is described with reference to FIG. 6.

First, when the door D is opened, the dead bolt 40 which has moved to the release position A2 returns to the locking position A1 again due to the restoring force of the spring 42.

Then, when the door D is opened, the pressing lever 60 moves from the pressed position E2 inside the housing 10 to the protruding position E1 outside. At this time, the pressing lever 60 moved to the protruding position E1 presses the pressing finger 55 of the blocking lever 50. In particular, it presses toward a release position C2.

Therefore, the blocking lever 50 is pressed to the release position C2, the pressed blocking lever 50 continues to hold the release position C2, and the blocking lever 50 which holds the release position C2 is Release the dead bolt 40.

As a result, since the dead bolt 40 is released, the dead bolt 40 can be retracted to the release position A2 inside the housing 10 even when the dead bolt 40 is disposed in the locking position A1.

Next, a case of closing the opened door D will be described with reference to FIG. 7.

First, when the door D is closed, one side portion 40a (see FIG. 2) of the dead bolt 40 is pressed by the door frame D1 to retreat to the release position A2 inside the housing 10. And when the door D is fully closed, it returns to the locking position A1 of the outer side of the housing 10 by the restoring force of the spring 42, and the returned dead bolt 40 is locked to the door frame D1.

On the other hand, in the process of closing the door (D), the pressing lever 60 is pressed to the door frame (D1) while moving from the protruding position (E1) outside the housing 10 to the inner pressing position (E2), in this case, The pressing lever 60 which has been moved to the pressing position E2 releases the pressing of the blocking lever 50.

Therefore, the blocking lever 50 returns to the blocking position C1 from the release position C2, and the blocking lever 50 returned to the blocking position C1 blocks the rear side of the dead bolt 40. As shown in FIG.

In this state, the dead bolt 40 is limited in retreat, and the dead bolt 40 in which the retreat is restricted is fixed. And the fixed dead bolt 40 prevents the forced release of the door (D).

Next, a case in which the door D is to be released by manipulating the inner handle 16 inside the door D will be described.

Referring to FIG. 8, a user inside the door D rotates the inner handle 16. Then, as the second rotating member 30 installed on the inner handle 16 is rotated and the second rotating member 30 is rotated, the first push piece 34 of the second rotating member 30 is blocked by a blocking lever ( 50) is pressurized.

At this time, the blocking lever 50 pressed by the first push piece 34 moves from the blocking position C1 to the release position C2, and the blocking lever 50 moved to the release position C2 is dead. Release the bolt 40. Thus, retraction of the dead bolt 40 is allowed.

On the other hand, when the user inside the door (D) further rotates the inner handle 16, the second push piece 35 of the second rotating member 30 presses the dead bolt (40). In particular, it presses from the locking position A1 to the release position A2. Then, the dead bolt 40 releases the door D while moving from the locking position A1 to the release position A2.

Next, FIG. 9 is a view showing a modification of the pressing means 80 for pressing the coupling pin 70.

The pressing means 80 of the modification, the driving means 90 is driven as the authentication signal is input, and the coupling pin 70 while moving from the original position (X1) to the pressing position (X2) by the driving means (90) ) Is provided with a pressing member 92 for urging the coupling position F2 in the direction.

In particular, the pressing member 92, by pressing the coupling pin 70 in the coupling position (F2) direction, so that the coupling pin 70 can be coupled to the coupling groove (30a), the coupling pin 70 is coupled By allowing the coupling to the groove 30a, the outer handle 14 and the inner handle 16 are integrated. Accordingly, when the outer handle 14 is rotated, the inner handle 16 may also be rotated at the same time to release the door D.

On the other hand, the pressing surface 92a of the pressing member 92 forms an arcuate curved surface along a concentric circle centered on the center of rotation shafts 14a and 16a of the inner and outer handles 14 and 16.

The drive means 90 is composed of a solenoid. The solenoid is operated according to the applied power to move the pressing member 92 from the original position (X1) to the pressing position (X2).

Since the pressurizing means 80 of this modification has a simple structure, there is no breakdown and the effect of cost reduction can be expected.

In the above described a preferred embodiment of the present invention by way of example, the scope of the present invention is not limited only to this specific embodiment, it can be changed appropriately within the scope described in the utility model registration claims.
