The first pin member 130 is fixed to the handle 120. The first pin member 130 rotates around the central axis of rotation of the handle 120 when the handle 120 is rotated. In addition, the handle 120 is elastically biased to return to its original state by a torsion spring (not shown), and when the handle 120 is rotated and released, the handle 120 returns to its original state.

The outdoor side part 200 has a handle 220 and a keypad 211 rotatably coupled to the outdoor side housing 210 and the outdoor side housing 210. The second pin member 230 is fixed to the handle 220, and the second pin member 230 rotates around the central axis of rotation of the handle 220 when the handle 220 is rotated. When a preset password is input to the keypad 211, the user is authenticated, thereby enabling the motor to be described later.

The mortise portion 300 is installed inside the door 1. The mortise portion 300 includes the housing 10, the dead bolt 20, the pressure rotating member 30, the intermediate driving member 40, the first rotating member 50, and the second rotating member 60. ), A latch bolt 70 and a latch pressurizing member 80.

The housing 10 is inserted into the door 1 so as not to protrude and immerse with respect to the side of the door 1. The housing 10 has a case 11, a front plate 12 and a cover 13 which are mutually coupled. The front plate 12 is provided with a dead bolt entry hole 121 through which the dead bolt 20 to be described later enters and a latch bolt entry hole 122 through which the latch bolt 70 described later enters and exits.

The dead bolt 20 is installed to be linearly movable in the housing 10. The dead bolt 20 is protruded with respect to the housing 10 through the dead bolt entrance hole 121, the dead bolt 20 is inserted into the dead bolt insertion hole (3) formed in the door post (2) to the door (1) Lock). On the contrary, the dead bolt 20 is released from the dead bolt insertion hole 3 to unlock the door 1. The dead bolt 20 is formed with a groove portion 21 opened downward.

The pressure rotating member 30 is elongated in one direction and rotatably coupled to the housing 10 about the pivot shaft 31. The pivot shaft 31 is coupled to the case 11 and the cover 13, respectively. An end portion of the pressure rotating member 30 is inserted into the groove portion 21.

Move it. In addition, the through hole 32 is formed in the pressure rotating member 30. The through-hole 32 is preferably as close as possible to the pivot shaft 31, because it can move the dead bolt 20 in the direction of protruding or immersing even if the interior handle 120 is rotated less. In the present embodiment, the center of the through hole 32 is disposed within a distance corresponding to at least half of the length from the pivot shaft 31 to the end of the pressure rotating member 30.

The pressure rotating member 30 and the dead bolt 20 are connected to each other by the torsion spring 22.

One end and the other end of the torsion spring 22 is fixed to the pressure rotating member 30 and the dead bolt 20, respectively.

The intermediate drive member 40 is for rotationally driving the pressure rotating member 30. The intermediate driving member 40 is installed in the housing 10 so as to be linearly movable, and the pressure rotating member 30 rotates in association with the linear movement of the intermediate driving member 40, thereby driving the dead bolt 20. You can do it. The intermediate drive member 40 includes a plate portion 41 formed to extend in the horizontal direction, a first protrusion portion 42, a second protrusion portion 43, and a third protrusion portion 44 protruding upward from the plate portion 41. ) And a fourth protrusion 45.

As shown in FIGS. 5 and 7, the first protrusion 42 and the second protrusion 43 protrude downward from the plate-shaped part 41. The first protrusion 42 and the second protrusion 43 are spaced apart from each other in the horizontal direction. The first protrusion 42 is inserted into the through hole 32 of the pressure rotating member, whereby the intermediate driving member 40 is pressed in the direction shown by the arrow in FIG. It is possible to rotate relative to 30. In this way, the connecting portion in which the intermediate driving member 40 and the pressure rotating member 30 are connected to each other is constituted by the through hole 32 and the first protrusion 42. In addition, the connection part may be disposed close to the center of rotation of the intermediate drive rotation member, that is, the pivot shaft 31 according to the position of the through hole 32. Both side surfaces of the second protrusion 43 are formed with a first pressurized surface 431 and a second pressurized surface 432 orthogonal to the linear movement direction of the intermediate driving member 40, respectively. The first and second pressurized surfaces 431 and 432 face in opposite directions to each other.

As shown in FIG. 5, the third protrusion 44 and the fourth protrusion 45 protrude upward from the plate-shaped part 41. The third protrusions 44 and the fourth protrusions 45 are spaced apart from each other in the horizontal direction and face each other. A third pressurized surface 441 including an inclined surface 442 and an orthogonal surface 443 is formed in the third protrusion 44. The inclined surface 442 of the third pressurized surface is formed to be inclined in a direction crossing the linear movement direction of the intermediate driving member 40, and the orthogonal surface 443 of the third pressurized surface is connected to the inclined surface 442. It is formed perpendicular to the linear movement direction of the intermediate drive member (40). The fourth protrusion 45 is provided with a fourth pressing surface 451 including an inclined surface 452 and an orthogonal surface 453. The fourth pressurized surface 451 is disposed to face the third pressurized surface 441. The inclined surface 452 of the fourth to-be-pressed surface is formed to be inclined in a direction crossing with the linear movement direction of the intermediate driving member 40. The inclined surface 442 of the third to-be-pressed surface and the inclined surface 452 of the fourth to-be-pressed surface are formed to face-symmetric with each other. The orthogonal surface 453 of the fourth pressurized surface is connected to the inclined surface 452 and is orthogonal to the linear movement direction of the intermediate driving member 40.

Then, the intermediate drive member 40 is elastically biased toward the first rotating member to be described later by the leaf spring 46. That is, the intermediate drive member 40 is installed to elastically bias downward in the state shown in FIG. Here, the leaf spring 46 is installed inside the housing 10.

The first rotation member 50 is rotatably coupled to the housing 10 and drives the linear movement of the intermediate drive member 40. The first rotating member 50 is formed with a plate-like portion 51 formed in a plate shape, and a first pressure protrusion 52 and a second pressure protrusion 53 which are formed to protrude from the outer surface of the plate and are spaced apart from each other. do. A second protrusion 43 of the intermediate driving member is disposed between the first pressure protrusion 52 and the second pressure protrusion 53. A first pressing surface 521 and a second pressing surface 531 are formed in the first pressing protrusion 52 and the second pressing protrusion 53, respectively. The first pressing surface 521 and the second pressing surface 531 are disposed to face each other, and the first pressing surface 521 and the second pressing surface 432 are also disposed to face each other. The first pressurizing surface 521 and the second pressurizing surface 531 are in contact with each other in contact with the first pressurized surface 431 and the second pressurized surface 432 during the rotation of the first rotating member 50. Pressurize Therefore, when the first rotating member 50 rotates in the clockwise direction in the state shown in FIG. 2, the first pressing surface 521 contacts the first pressing surface 431 to turn the intermediate driving member 40 to the right. 3, when the first rotary member 50 rotates counterclockwise in the state shown in FIG. 3, the second pressing surface 531 contacts the second pressurized surface 432 so as to mediate the driving member 40. ) To move to the left.

On the other hand, the first rotating member 50 is driven by a motor (not shown) installed in the housing 10. The interlocking structure of the first rotating member 50 and the motor (not shown) is directly engaged with a gear part (not shown) and a gear part composed of a plurality of gears formed on the plate portion 51 of the first rotating member 50 and the motor. It is configured to include a pinion (not shown) coupled to the output shaft of. And, if a predetermined password is input to the keypad 211, the user is authenticated to operate the motor. In addition, the motor operates to automatically lock the door 1 again when the unlocked door 1 is closed again.

In addition, a first groove 511 and a second groove 512 into which the first pin member 130 and the second pin member 230 are inserted are formed in the plate portion 51 of the first rotating member. The first and second fin members 511 and 512 may be formed of the first pin member 130 and the second pin member 230 when the first pin member 130 and the second pin member 230 are rotated. It is formed sufficiently large so as not to contact the inner surfaces of the first groove portion 511 and the second groove portion 512, respectively. In particular, in the present embodiment, the first groove 511 and the second groove 512 are formed in a shape that forms part of an arc.

The second rotation member 60 is rotatably coupled to the housing 10 and drives the linear movement of the intermediate drive member 40. The second rotating member 60 is disposed to be spaced apart from each other in the thickness direction of the first rotating member 50 and the door 1, and is disposed coaxially with the first rotating member 50. The second rotating member 60 includes a plate-shaped portion 61 formed in a plate shape, and a pressure protrusion 62 protruding from the outer surface of the plate-shaped portion.

The pivot shaft 611 is coupled to the plate portion 61. Here, the pivot shaft 611 is coupled to the case 11 and the cover 13, respectively. In addition, the plate portion 61 is provided with a groove 612 inserted into the first pin member 130 and formed in a shape forming a part of an arc. When the first pin member 130 is rotated about the pivot shaft 611 in conjunction with the indoor handle 120, the first pin member 130 is in contact with the inner surface of the groove portion 612 is pressed , The second rotating member 60 is rotated in the pressing direction.

The pressure protrusion 62 is disposed between the third protrusion 44 and the fourth protrusion 45 of the intermediate driving member. The pressurizing protrusion 62 is provided with a first pressurizing surface 621 and a second pressurizing surface 622 facing the third pressurized surface 441 and the fourth pressurized surface 451, respectively. The first pressing surface 621 and the second pressing surface 622 are planes perpendicular to the linear movement direction of the intermediate driving member 40 and face in opposite directions to each other. The first pressurizing surface 621 and the second pressurizing surface 622 contact with the third pressurized surface 441 and the fourth pressurized surface 451 in a direction opposite to each other during the rotation of the second rotating member 60. Pressurize

Then, when the second rotating member 60 is rotated to release the door 1, the first rotating member is moved from the linear movement path of the intermediate driving member 40 by linear movement after the intermediate driving member 40 rotates. 50 is placed out of the way. That is, when the second rotary member 60 rotates in the clockwise direction in the state shown in FIG. 2, since the second pressing surface 622 of the pressing protrusion is in contact with the inclined surface 452 of the fourth pressing surface, the pressure is 1. As shown in FIG. 8, the intermediate driving member 40 is rotated. Then, from the moment when the second pressing surface 622 of the pressurizing protrusion is in contact with the orthogonal surface 453 of the fourth pressing surface, the intermediate driving member 40 does not rotate any more and is turned right in the state shown in FIG. 8. Will move straight. Therefore, in the unlocking process of the door 1, the intermediate driving member 40, in particular, the second protrusion 43 of the intermediate driving member does not contact the first rotating member 50.

The latch bolt 70 is linearly movable in the direction in which the latch bolt 70 protrudes and immerses with respect to the housing 10. The latch bolt 70 includes a latch member 71 and a coupling member 72.

The latch member 71 is inserted into the latch bolt insertion hole 4 while the door 1 is closed to prevent the door from being opened arbitrarily by wind or weak vibration. The latch member 71 is inserted into the latch bolt access hole 122 and elastically biased in a direction projecting from the housing 10 by the compression coil spring 73. Here, the compression coil spring 73 is installed so that one end is in contact with the latch member 71 and the other end is in contact with the support 111 protruding from the case. The end of the latch member 71 is formed to be inclined with respect to the linear movement direction of the latch member 71 so that the latch bolt 70 is pressed against the housing 10 when the door 1 is opened and closed. Allow you to move in the direction you are immersed.

The latch member 71 is fitted and coupled to the coupling member 72. Accordingly, the coupling member 72 and the latch member 71 are configured in one body to linearly move in the same direction. The linear movement of the coupling member 72 is guided by a pair of guide portions 112. Here, the pair of guide portions 112 are formed to protrude on the inner surface of the case 11 and are disposed in parallel to each other.

The latch pressing member 80 is rotatably coupled to the housing 10. The latch pressing member 80 has a first wing 82 and a second wing 83 formed long in different directions with respect to the pivot shaft 81 which is the rotation center. The pivot shaft 81 is coupled to the case 11 and the cover 13 through the latch pressing member 80. The first blade portion 82 is disposed in contact with the coupling member 72. The second blade portion 83 is disposed to face the second rotating member 60 and the second pin member 230 with a narrow gap therebetween. Therefore, when the second rotating member 60 or the second pin member 230 is rotated, the second blade portion 83 is pressed by the second rotating member 60 or the second pin member 230 to counterclockwise. Direction, the latch bolt 70 is linearly moved in a direction immersed with respect to the housing (10).

In the door lock device configured as described above, a preset password is input to the keypad 211 in order to unlock the door at the outdoor side of the door while the door 1 is locked as shown in FIG. When the motor is operated by authenticating the user, the first rotating member 50 rotates so that the first pressing surface 521 of the first pressing protrusion urges the first pressing surface 431 of the second protrusion. The intermediate drive member 40 is linearly moved to the right. When the intermediate driving member 40 moves in this way, the first protrusion 42 of the intermediate driving member presses the inner surface of the through hole 32 of the pressure rotating member, so that the pressure rotating member 30 rotates. Done. In addition, since the pressure rotating member 30 presses the inner surface of the groove 21 of the dead bolt, the dead bolt 20 is moved in a direction immersed with respect to the housing 10, so that the door is unlocked. Meanwhile, in the unlocking process of the door by the first rotating member 50, the third protrusion 44 and the fourth protrusion 45 of the intermediate driving member do not contact the pressure protrusion 62 of the second rotating member.

As described above, when the outdoor handle 220 is rotated while the door 1 is unlocked, the second pin member 230 presses the second blade portion 83 of the latch pressing member to latch the bolt 70. ) Is linearly moved in the direction immersed with respect to the housing (10). Accordingly, the door 1 may be opened to enter the indoor side by turning the outdoor handle 220.

On the other hand, in order to release the door lock from the interior side of the door 1, the interior handle 120 only needs to be turned. That is, when the interior handle is rotated in the state shown in FIG. 2, the first pin member 130 is rotated, and the first pin member 130 is in the groove 612 of the second rotating member during the rotation process. Press the side to rotate the second rotating member 60 in the clockwise direction. In the rotation process of the second rotating member 60, since the second pressing surface 622 of the pressing protrusion sequentially presses the inclined surface 442 and the orthogonal surface 443 of the third pressing surface, the intermediate driving member ( 40 is linearly moved to the right in the rotated state as shown in FIG. At this time, the interference between the intermediate driving member 40 and the first rotating member 50 does not occur. When the intermediate drive member 40 moves in this way, the pressure rotating member 30 is rotated so that the dead bolt 20 moves in the direction in which the door is immersed in the housing, thereby releasing the locking of the door. In addition, the latch pressing member 80 is also pressed by the second rotating member 60 to rotate in the process of rotating the second rotating member 60. As a result, the latch bolt 70 also linearly immerses with respect to the housing. Will move. Accordingly, simply turning the indoor handle 120 moves the dead bolt 20 and the latch bolt 70 in the direction to be immersed in the housing 10 at the same time to open the door and go out to the outdoor side.

On the other hand, after the interior handle 120 is rotated and the door 1 is unlocked, the unlocking of the door is detected, and a motor (not shown) is automatically operated, thereby rotating the first rotating member 50. Let's do it. When the first rotating member 50 rotates as described above, the second protrusion 43 of the intermediate driving member is disposed between the first pressing protrusion 52 and the second pressing protrusion 53 of the first rotating member. In this state, when the door 1 is opened and then closed again, the closing of the door is automatically sensed and the motor is operated so that the dead bolt 20 protrudes with respect to the housing. Thus, the door is automatically locked. In addition, the door may be manually locked again by rotating the indoor handle 120 at the indoor side. That is, when the interior handle 120 is rotated in a direction opposite to the direction in which the interior handle 120 is rotated when the door is unlocked, the pressing protrusion 62 of the second rotating member moves to the left side. Since the inclined surface 442 and the orthogonal surface 443 constituting the third pressurized surface 441 are sequentially pressed, the intermediate driving member 40 rotates to the left side in a state similar to that when releasing the locking of the door. It will move straight. In addition, since the pressure rotating member rotates in association with the linear movement of the intermediate driving member 40, the dead bolt 20 can be eventually moved in a direction protruding with respect to the housing 10.

As described above, in the present embodiment, even if only two rotating members 50 and 60 are installed in the mortise unit 300, the door can be locked and unlocked at the indoor side and the outdoor side of the door. Therefore, the structure of the mortise portion is simplified, thereby making it easy to manufacture and assemble, and further improve durability.

In particular, since the door can be unlocked and the door can be opened and released at the same time by simply rotating the handle 120, it is possible to easily escape even in an emergency such as a fire or an earthquake. In addition, since the interference between the first rotating member 50 and the intermediate driving member 40 does not occur when the second rotating member 60 rotates, the motor is damaged when the second rotating member 60 rotates. Can be prevented.

In addition, the connection portion connecting the pressure rotating member 30 and the intermediate driving member 40, that is, the first protrusion 42 inserted into the through hole 32 is disposed close to the pivot shaft 31 of the pressure rotating member. Even if the interior handle 120 is slightly rotated, the pressure rotating member 30 may be sufficiently rotated to move the dead bolt 20 in a protruding and immersing direction with respect to the housing. Therefore, ease of use is improved.

On the other hand, unlike in the door lock device shown in Figures 1 to 7, as shown in Figure 8 may be configured so that only one protrusion is formed in the intermediate driving member and the second rotating member includes two pressing projections. .

That is, referring to FIG. 8, in the mortise portion 300a of the present embodiment, the intermediate driving member 40a is provided with one protrusion 47. The protruding portion 47 protrudes from the plate portion 41, and includes a first pressing surface 471, a second pressing surface 472, a third pressing surface 473, and a fourth pressing surface 474. ). The first pressurized surface 471 and the third pressurized surface 473 are disposed in plane symmetry with respect to the second pressurized surface 472 and the fourth pressurized surface 474. Here, the third pressurized surface 473 and the fourth pressurized surface 474 are formed to include only the inclined plane.

The first pressing protrusion part 63 and the second pressing protrusion part 64 are formed in the second rotating member 60a. A first pressing surface 631 and a second pressing surface 641 are formed in the first pressing protrusion 63 and the second pressing protrusion 64, respectively. A protrusion 47 of the intermediate driving member is disposed between the first pressurizing protrusion 63 and the second pressurizing protrusion 64.

The first pressing surface 631 of the first pressing projection part rotates the intermediate driving member 40a by primarily pressing the third pressurized surface 473 when the second rotating member 60a is rotated in the clockwise direction. After the secondary pressure, the first pressurized surface 471 is pressurized to move the intermediate driving member 40a to the right.

The second pressing surface 641 of the second pressing projection part primarily presses the fourth pressure pressing surface 474 when the second rotating member 60a rotates in the counterclockwise direction to press the intermediate driving member 40a. After rotation, the second driven surface 472 is secondarily pressed to move the intermediate driving member 40a to the left.

As mentioned above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the technical idea of the present invention. It is obvious.

For example, in the present embodiment, the first and second pressurized surfaces are formed to be formed in the first protrusion, but grooves are formed in the intermediate driving member, and the first pressurized surfaces are respectively formed on the inner surfaces of the grooves. And a second pressurized surface.

In addition, in the present embodiment, a so-called primary key type door lock device including a dead bolt, a latch bolt, an indoor handle, and an outdoor handle is disclosed. However, the present invention is not only a main key type door lock device but also an auxiliary key type door lock device. That is, it may be configured to include a knob that is rotatably coupled to the dead bolt and the indoor side without the indoor handle, the outdoor handle and the latch bolt. Here, the second rotating member is rotated in conjunction with the rotation of the knob, in the door lock device of the auxiliary key type, the dead bolt insertion hole and the latch bolt insertion hole is not formed in the door holder, the dead bolt insertion hole and the latch bolt insertion hole formed a cap member It is fixed to the doorpost separately.

In addition, in the present embodiment, the first pin member and the second pin member are configured to rotate in conjunction with the rotation of the indoor handle and the outdoor handle, respectively, but by using various link devices to convert the rotation of the handle into linear movement.
