The case 10 protects each component of the door lock mortis, and is mounted on the door. In addition, on the outdoor side of the case 10, a key hole in which a user can insert a key to open the door, a key input part or a card contact part for releasing the latch bolt 100 and the dead bolt 200 are mounted. could be

In addition, on the indoor side of the case 10, a push-pull handle (not shown) for a user to release the latch bolt 100 and the dead bolt 200 in the room is provided, and push the push-pull handle (not shown) or a conversion rotation shaft (not shown) that converts a pulling force into a rotational force is formed inside the case 10 to push or pull a push-pull handle (not shown), which will be described later by converting the pushing force from the converting rotation shaft (not shown) into a rotational force. The first handle block 910 and the third handle block 930 are rotated. Since such a conversion rotation shaft (not shown) is a known technology, a detailed description thereof will be omitted.

The body front 20 is formed to face the side of the case 10, that is, the striker (not shown), and an inlet through which the latch bolt 100 , the dead bolt 200 and the sub latch 300 can enter and exit is formed. has been

The latch bolt 100 is provided to maintain a closed state that prevents the door from being opened by itself, and when the door is closed in an open state, it touches the door frame and at the same time protrudes so that the latch bolt 100 can enter in a straight line. has been

The latch bolt 100 is elastically supported by a spring 130 formed on the rear surface as shown in FIGS. 3 and 4, and is in contact with the inner surface of the body front 20 on one side of both sides so that the latch bolt 100 is A protrusion 120 for limiting rotation of the latch bolt 100 by contacting with the locking jaw 110 for preventing the body front 20 from escaping to the outside and the rotation limiting part 720 of the latch lever 700 is provided. is formed

As shown in FIG. 4( a ), as the pressing part 730 is pushed by the elastic force of the spring 740 formed on the pressing part 730 of the latch lever 700 , the latch lever 700 rotates the rotation shaft 701 . The rotation limiting part 720 of the latch lever 700 is drawn in through the groove 151 of the frame 150 by rotating clockwise in the drawing with respect to the center, so that the lower surface of the rotation limiting part 720 is the latch bolt 100. When in contact with the upper surface of the protrusion 120 of the rotation of the latch bolt 100 is limited, as shown in Fig. 4 (b), the pressing portion 730 of the latch lever 700 by an external force is a spring ( While pressing 740 , the latch lever 700 rotates counterclockwise around the rotation shaft 701 in the drawing so that the rotation limiting part 720 of the latch lever 700 is moved from the protrusion 120 of the latch bolt 100 . When it is separated, the rotation of the latch bolt 100 is allowed. At this time, in the present invention, a reinforcing material is formed between the upper and lower surfaces of the rotation limiting part 720 of the latch lever 700 to prevent the rotation limiting part 720 from being deformed or damaged by repeated use. Specifically, when the space between the upper and lower surfaces of the rotation limiting part 720 is formed as an empty space, the rotation limiting part 720 is continuously subjected to a force by the protrusion 120 of the latch bolt 100 to cause deformation. If it is bent or severe, it may be damaged. In the present invention, by forming a reinforcing material between the upper and lower surfaces of the rotation limiting part 720, the rigidity of the rotation limiting part 720 is improved, and the latch bolt 100 is It can be prevented from being deformed or damaged even when a force is continuously applied by the protrusion 120 .

In addition, the pressing part 730 of the latch lever 700 is integrally formed with the driven gear 143 that rotates by receiving the rotational force through the second motor 141 and the second driving gear 142 to be described later. 146), and accordingly, the pressing part 730 of the latch lever 700 is moved forward by the rotation of the pressing protrusion 146, and the latch lever 700 is rotated around the rotation shaft 701. By rotating, the rotation limiting part 720 of the latch lever 700 is separated from the protrusion 120 of the latch bolt 100 to enable rotation of the latch bolt 100 . A detailed description thereof will be provided later.

The dead bolt 200 is configured to lock or unlock the door by being drawn out and drawn in through the inlet hole of the body front 20, and the rear of the dead bolt 200 is towed by the first dead bolt rotating by external force or power. A slider 201 that linearly moves forward and backward through the lever 210 and the second dead bolt traction lever 211 to draw in and withdraw the dead bolt 200 from the body front 20 is integrally formed.

The end of the second dead bolt traction lever 211 is drawn into the long hole 202 formed in the slider 201 , and the first dead bolt traction lever 210 is formed to contact the panic lever 400 to be described later.

Accordingly, when the first and second dead bolt traction levers 210 and 211 are rotated clockwise or counterclockwise in the drawing by receiving the driving force of the first motor 221 to be described later, the second dead bolt traction lever 211 . While the end of the slider 201 moves to the top or bottom along the long hole 202 of the slider 201, the slider 201 is pushed forward or pulled back to withdraw or retract the dead bolt 200. In addition, the first handle block 910 and the third handle block 930 in which the panic lever 400 to be described later rotates by a user's manipulation of a push-pull handle (not shown) or a second handle block rotates by a key manipulation When it rotates in contact with the panic lever 400, the first dead bolt traction lever 210 in contact with the panic lever 400 rotates while the second dead bolt traction lever 211 rotates at the same time to rotate the second dead bolt traction lever 211 ) moves to the bottom along the long hole 202 of the slider 201 to introduce the dead bolt 200 . A detailed description of the retracting and withdrawing operations of the dead bolt 200 will be described later.

On the other hand, a torsion spring 230 is coupled to one side of the second dead bolt traction lever 211, and the torsion spring 230 acts as an elastic force when compressed like a conventional spring, and accordingly, the second dead bolt traction lever At the initial stage of rotation of 211, the second deadbolt traction lever 211 rotates slowly by the elastic force because it rotates while compressing the torsion spring 230 in the opposite direction to the direction in which the elastic force of the torsion spring 230 acts. Accordingly, when the dead bolt 200 is slowly retracted and the second dead bolt traction lever 211 rotates by a predetermined angle, the elastic force of the torsion spring 230 acts, that is, in the direction in which the torsion spring 230 is tensioned. Since the torsion spring 230 is immediately tensioned because it rotates, the second dead bolt traction lever 211 also rotates rapidly in accordance with it, and the dead bolt 200 is immediately drawn in. That is, when the dead bolt 200 is retracted by the user's operation of a push-pull handle (not shown) or a key, it is slowly retracted at the beginning and immediately after being retracted by a certain distance, the total area of the dead bolt 200 is the body It is introduced through the inlet hole of the front (20).

The sub-latch 300 is configured to detect the closed and open state of the door by being drawn in and out of the body front 20, and since a space into which the sub-latch 300 can be introduced is not formed in the door frame, the door is closed. When closed, the sub-latch 300 is retracted into the body front 20 , and when the door is opened, the sub-latch 300 is drawn out from the body front 20 by the elastic force of the spring 301 formed on the rear surface. In addition, a pressing protrusion 302 is formed on one side of the side of the sub-latch 300 by pressing the protrusion 602 of the pull bar 600 to be described later to lift the engaging protrusion 601 of the pull bar 600 . . A detailed description thereof will be provided later.

When the slider 201 moves forward and the dead bolt 200 is withdrawn, the detection unit 203 is positioned on the closure sensor 820, and the closure sensor 820 detects this and the dead bolt 200 is removed. When it is determined that the slider 201 is moved backward and the dead bolt 200 is retracted, the detection unit 203 is located on the open sensor 810 and is detected by the open sensor 810. It is determined that the dead bolt 200 is inserted.

In addition, when the sub-latch 300 is retracted and the sensing unit 303 is spaced apart from the sub-latch detecting sensor 830, the sub-latch detecting sensor 830 determines that the door is closed, and the sub-latch 300 is withdrawn. When the detection unit 303 comes into contact with the sub-latch detection sensor 830 , the sub-latch detection sensor 830 determines that the door is open.

The first and second gearboxes 220 and 140 are provided with first and second motors 221 and 141 and first and second driving gears 222 and 142, respectively, and the first and second motors 221 , respectively. , The driven gear 143 in which the dead bolt traction gear 213 and the pressing protrusion 146 are integrally formed with the first and second drive gears 222 and 142 that rotate by receiving the rotational force of the 141 are engaged and rotate together will do Accordingly, when the first driving gear 222 and the dead bolt traction gear 213 rotate by the driving of the first motor 221 , the first and second dead bolts integrally formed with the dead bolt traction gear 213 . The traction levers 210 and 211 rotate together so that the end of the second dead bolt traction lever 211 moves up and down in the long hole 202 of the slider 201, so that the slider 201 and the slider 201 are integrally formed. The dead bolt 200 is drawn in and out from the body front 20 .

In addition, when the second driving gear 142 and the driven gear 143 are rotated by the driving of the second motor 141, the pressing protrusion 146 formed integrally with the driven gear 143 rotates together and the latch lever By moving the pressing part 730 of the 700 forward and backward, the latch lever 700 is rotated about the rotation shaft 701 so that the rotation limiting part 720 of the latch lever 700 is the protrusion of the latch bolt 100 ( 120) to limit or allow rotation of the latch bolt 100 by pressing or releasing the pressure. At this time, the cam 144 is integrally formed with the driven gear 143, and the limiting parts 145 are formed at both ends of the cam 144 in a state that they are spaced apart from each other by a predetermined distance, and accordingly, the limiting parts 145 are formed. By limiting the rotation radius of the false cam 144, the rotation radius of the driven gear 143 and the pressing protrusion 146 is limited.

As shown in FIG. 5 , the first to third handle blocks 910 , 920 and 930 are integrally coupled to the first handle block 910 and the third handle block 930 through a coupling pin 940 . It rotates at the same time and the second handle block 920 is sandwiched between the coupling of the first handle block 910 and the third handle block 930, and the second handle block 920 includes the first handle block 910 and the second handle block 920. 3 When the handle block 930 rotates, a guide groove 922 is formed so that it can rotate independently without colliding with the second handle block 920, and a locking means 932 is provided in the third handle block 930. this is formed The first to third handle blocks 910, 920, and 930 are formed from a position close to the outdoor side, that is, from the upper side to the lower side in the drawing, the first handle block 910 (located at the upper side in the drawing), the second handle block ( 920 (located between the first handle block 910 and the third handle block 930), the third handle block 930 (located on the lower side in the drawing) is concentrically coupled in the order, and the second handle block ( When a user uses a key, a second coupling hole 921 of a polygonal shape to which the outdoor conversion rotation shaft connected to the key is coupled is formed, and the third handle block 930 has a polygonal shape to which the indoor conversion rotation shaft is coupled. of the third coupling hole 931 is formed, the first handle block 910 has the same shape and size as the third coupling hole 931 and a first coupling hole 911 to which nothing is connected is formed .

The indoor conversion rotation shaft converts the force of pressing or pulling the push-pull handle of the door lock mortise into the rotational force of the third handle block 930 for the operation of the push-pull method, and is integrally coupled with the third handle block 930. 1 It is a part that rotates together with the handle block 910, and the outdoor conversion rotation shaft is connected to the key and rotates with the rotation of the key.

The outdoor conversion rotation shaft is seated and coupled to the second coupling hole 921, the indoor conversion rotation shaft is seated and coupled to the third coupling hole 931, and the key is connected to the outdoor conversion rotation shaft. Therefore, when a key is inserted and rotated from the outside, only the second handle block 920 coupled with the outdoor conversion rotation shaft and the outdoor conversion rotation shaft rotates, and when you push or pull the push-pull handle (not shown), the indoor conversion rotation shaft and the indoor The third handle block 930 to which the conversion rotation shaft is coupled and the first handle block 910 integrally coupled to the third handle block 930 are rotated together.

When the user rotates the indoor conversion rotation shaft by pushing or pulling a push-pull handle (not shown) indoors by this structure, the second handle block 920 is fixed and the third handle block 930 is rotated, at this time The 3 handle block 930 and the first handle block 910 rotate together because they are connected, and the third handle block 930 rotates in a clockwise direction in the drawing to rotate the abutting panic lever 400 and , the panic lever 400 rotated by the third handle block 930 comes into contact with the first dead bolt traction lever 210 to rotate the first dead bolt traction lever 210 counterclockwise in the drawing.

Accordingly, the second dead bolt traction lever 211 integrally formed to rotate simultaneously with the first dead bolt traction lever 210 rotates at the same time so that the end of the second dead bolt traction lever 211 is the long hole of the slider 201 . The dead bolt 200 is introduced into the body front 20 by moving to the bottom along the 202, and then the panic lever 400 rotates further in the clockwise direction in the drawing, and the lower locking jaw 710 of the latch lever 700 ) and rotate the latch lever 700 around the rotation shaft 701 to separate the rotation limiting part 720 from the protrusion 120 of the latch bolt 100 to allow rotation of the latch bolt 100 . At this time, as shown in FIG. 2, the panic lever 400 is in contact with the first dead bolt traction lever 210 and is separated from the lower engaging jaw 710 of the latch lever 700 by a certain distance. 200) is completed, the panic lever 400 and the lower engaging jaw 710 of the latch lever 700 start to contact, the latch bolt 100 is released, and the panic lever 400 and the latch lever ( Each of the elastic springs 410 and 740 is formed in 700 , so that when the external force is removed, the panic lever 400 and the latch lever 700 are automatically returned to their original positions by the elastic force.

In addition, as the third handle block 930 rotates, the locking means 932 integrally formed with the third handle block 930 also rotates in a clockwise direction in the drawing to show the engaging projection 601 of the draw bar 600 . move from upper right to left.

In addition, as shown in FIG. 14, the draw bar 600 moves up and down in the opposite direction to the left and right protrusions 602 and the locking jaw 601 about the central hinge axis 604 like a seesaw (that is, When the protrusion 602 rises, the locking jaw 601 descends, and when the protrusion 602 descends, the locking jaw 601 rises), and a spring 603 is formed at the lower end of the protrusion 602 so that an external force is applied. If it is not applied, the protrusion 602 is always maintained in an elevated state and the engaging jaw 601 is maintained in a descended state, and the engaging jaw 601 of the draw bar 600 is formed in a gentle curved shape on the right side of the drawing, and , the left side in the drawing is formed in a straight shape, so even in a state in which the locking jaw 601 is lowered, the locking means 510 is movable from the right to the left in the drawing of the locking jaw 601, but the drawing of the locking jaw 601 It is impossible to move from the upper left to the right, and it is possible to move only when the locking jaw 601 rises.

According to the operation of the push-pull handle (not shown) by the structure as described above, the third handle block 930 is rotated so that the locking means 932 is moved from the right to the left in the drawing of the engaging jaw 601 of the draw bar 600 . In the state of moving to , even if the panic lever 400 pushes the third handle block 930 by the elastic force of the spring 410 , the locking means 932 is not caught on the left side of the locking jaw 601 and cannot be passed over.

On the other hand, Figure 21 is a perspective view showing the internal structure of the door lock mortise according to another embodiment of the present invention.

Hereinafter, a door lock mortise according to another embodiment of the present invention will be described with reference to FIG. 21, but a description of the same configuration as the previous embodiment will be omitted for convenience of description.

21, the door lock mortise according to another embodiment of the present invention is a case 10, a body front 20, a latch bolt 100, the first and second gearboxes 220 and 140, the dead It includes a bolt 200, an auxiliary dead bolt 500, a sub-latch 300, first to third handle blocks 910, 920, 930, and a PCB 330, and a case 10, a body front 20 ), the latch bolt 100 , the first and second gearboxes 220 , 140 , and the PCB 330 are the same as in the above-described embodiment, and thus a detailed description thereof will be omitted.

The dead bolt 200 is configured to lock or unlock the door by being drawn out and drawn in through the inlet hole of the body front 20, and the dead bolt traction lever ( The slider 201 that linearly moves forward and backward through 210 to draw in and withdraw the dead bolt 200 from the body front 20 is integrally formed.

The dead bolt traction lever 210 is inserted into the slider groove 204 formed in the slider 201 , and the dead bolt traction lever 210 is formed to contact the panic lever 400 .

Accordingly, when the driving force of the first motor 221 is received and the dead bolt traction lever 210 rotates clockwise or counterclockwise in the drawing, the dead bolt traction lever 210 moves the slider groove 204 of the slider 201 . While moving along, it comes into contact with the inner surface of the slider groove 204 and pushes the slider 201 forward or pulls it backward to withdraw or retract the dead bolt 200 . In addition, the first handle block 910 and the third handle block 930 rotated by the panic lever 400 by the user's operation of a push-pull handle (not shown) or the second handle block 920 rotated by the operation of the key. ), the dead bolt traction lever 210 in contact with the panic lever 400 rotates and moves along the slider groove 204 of the slider 201 to retract the dead bolt 200 .

The first to third handle blocks 910 , 920 and 930 are integrally coupled to the first handle block 910 and the third handle block 930 and rotate at the same time, and the first handle block 910 and the third handle block The second handle block 920 is sandwiched between the couplings of the 930, and protrusions are formed in both directions on one side of the second handle block 920 and the third handle block 930 in clockwise and counterclockwise directions. It is possible to rotate the panic lever 400 by rotating in both directions.

With this structure, when a user pushes or pulls a push-pull handle (not shown) indoors, the second handle block 920 is fixed and the third handle block 930 is rotated, and at this time, the third handle block 930 is rotated. and the first handle block 910 rotate together because they are connected, and the third handle block 930 rotates in a clockwise or counterclockwise direction in the drawing to rotate the abutting panic lever 400, 3 The panic lever 400 rotated by the handle block 930 comes into contact with the dead bolt traction lever 210 to rotate the dead bolt traction lever 210 counterclockwise in the drawing.

Accordingly, the dead bolt traction lever 210 moves along the slider groove 204 of the slider 201 and comes into contact with the inner wall on the right side in the drawing of the slider groove 204, thereby removing the dead bolt 200 from the body front 20. Then, the panic lever 400 rotates further in the clockwise direction as shown in the drawing and comes into contact with the lower engaging jaw 710 of the latch lever 700 to rotate the latch lever 700 around the rotation shaft 701. Rotation of the latch bolt 100 is allowed by separating the limiting part 720 from the protrusion 120 of the latch bolt 100 .

Thereafter, as the panic lever 400 rotates counterclockwise in the drawing by the spring 410 and returns to its original position, the panic lever 400 and the dead bolt traction lever 210 are spaced apart from each other so that the dead bolt traction lever 210 is By being rotatable, the dead bolt 200 can be pulled out by driving the first motor 221 , and the lower engaging jaws 710 of the panic lever 400 and the latch lever 700 are spaced apart from each other. As the latch lever 700 is made rotatable, the latch lever 700 rotates clockwise by the elastic force of the spring 740 formed on the pressing part 730 of the latch lever 700 in the drawing, so that the latch lever 700 is rotatable. The rotation limiter 720 is introduced through the side groove 151 of the frame 150 to press the protrusion 120 of the latch bolt 100 to limit the rotation of the latch bolt 100 .

Meanwhile, when the user inserts and rotates the key outdoors, the first handle block 910 and the third handle block 930 are fixed and only the second handle block 205 rotates together with the key.

With this structure, when the user inserts and rotates the key outdoors, the first handle block 910 and the third handle block 930 are fixed, and only the second handle block 920 is clockwise or counterclockwise in the drawing. Rotates the panic lever 400 in contact while rotating, and the panic lever 400 rotated by the second handle block 920 comes into contact with the dead bolt traction lever 210 to remove the dead bolt traction lever 210. Rotate counterclockwise in the drawing.

Accordingly, the dead bolt traction lever 210 rotates and follows the slider groove 204 of the slider 201 and comes into contact with the right inner wall of the slider groove 204, thereby attaching the dead bolt 200 to the body front 20. After retracting, the panic lever 400 rotates further in the clockwise direction as shown in the drawing and comes into contact with the lower engaging jaw 710 of the latch lever 700 to rotate the latch lever 700 around the rotation shaft 701 to limit rotation. Rotation of the latch bolt 100 is allowed by disengaging the portion 720 from the protrusion 120 of the latch bolt 100 .

Thereafter, when the user rotates the key back to the original position, the second handle block 920 also rotates at the same time to return to the original position and is separated from the panic lever 400, and accordingly, the panic lever 400 by the elastic force of the spring 410. ) is also rotated counterclockwise in the drawing to return to the original position.

In addition, as the panic lever 400 rotates counterclockwise in the drawing by the spring 410 and returns to its original position, the panic lever 400 and the dead bolt traction lever 210 are spaced apart from each other so that the dead bolt traction lever 210 is By being rotatable, the dead bolt 200 can be pulled out by driving the first motor 221 , and the lower engaging jaws 710 of the panic lever 400 and the latch lever 700 are spaced apart from each other. As the latch lever 700 is made rotatable, the latch lever 700 rotates clockwise by the elastic force of the spring 740 formed on the pressing part 730 of the latch lever 700 in the drawing, so that the latch lever 700 is rotatable. The rotation limiter 720 is introduced through the side groove 151 of the frame 150 to press the protrusion 120 of the latch bolt 100 to limit the rotation of the latch bolt 100 .

On the other hand, the door lock mortis according to another embodiment of the present invention is additionally formed with an auxiliary deadbolt 500 that the user can operate only indoors, and this auxiliary deadbolt 500 allows the user to turn the locking device in a clockwise direction indoors. Alternatively, when the rotation block 520 is rotated counterclockwise, it is drawn in or withdrawn from the body front 20 by moving the advancing and retreating block 510 backward or forward while rotating in the clockwise or counterclockwise direction. At this time, a torsion spring 530 is coupled to one side of the rotation block 520 , and the torsion spring 530 exerts an elastic force during compression like a conventional spring, and accordingly, the rotation block 520 is initially rotated. Since the torsion spring 530 rotates while compressing it in a direction opposite to the direction in which the elastic force of the torsion spring 530 acts, the auxiliary dead bolt 500 is slowly drawn in and then rotates as the rotation block 520 is gradually rotated by the elastic force. When the block 520 rotates by a certain angle, the torsion spring 530 is immediately tensioned while rotating in the direction in which the elastic force of the torsion spring 530 acts, that is, in the direction in which the torsion spring 530 is tensioned. The auxiliary dead bolt 500 is immediately retracted while the 520 also rotates rapidly in accordance with it.

As described in detail above, in the door lock mortis according to the present invention, when a user operates a push-pull handle from the inside or inserts a key from the outside to turn it, the third handle block and the second handle block rotate the panic lever, and the panic lever By rotating the first and second dead bolt traction levers and latch levers while rotating to release the dead bolt and latch bolt, the user can immediately release the dead bolt and the latch bolt through the handle or key, so the door can be opened quickly There is an effect that can be done.

In addition, since the latch bolt is automatically released by the motor, the door can be easily opened by automatically releasing the dead bolt and the latch bolt by the motor without the user operating the handle.

The above-described preferred embodiments of the present invention have been disclosed for purposes of illustration, and those skilled in the art with ordinary knowledge of the present invention will be able to make various modifications, changes and additions within the spirit and scope of the present invention, and such modifications, changes and additions are to be considered as falling within the scope of the claims of the present invention.
