When the door is locked as shown in FIG. 2, when the dead bolt 20 is pushed in the direction to be immersed in the housing, the dead bolt 20 is caught by the catching portion 52 to limit the movement of the dead bolt. Therefore, in the state in which the door 2 is locked, the dead bolt 20 is forcibly pushed and the locking of the door 2 cannot be released arbitrarily.

The pressing part 53 is caught by the locking jaw 31 of the intermediate member during the rotation of the rotating member 50 in the clockwise direction. Then, from the moment when the pressing portion 53 is caught by the locking jaw 31, the intermediate member 30 is pressed to linearly move the intermediate member 30 to the right. Therefore, when the rotating member 50 is rotated in the state where the dead bolt 20 is protruded to the housing 10, the dead bolt 20 is moved in the direction immersed with respect to the housing 10 is shown in FIG. As described above, the locking of the door 2 is released. The rotating member is elastically biased by a torsion spring (not shown) so as to rotate counterclockwise in the state shown in FIG. 4, that is, in a direction in which the pressurization is released.

Both ends of the rotating body 60 are inserted into the case 11 and the cover 13. The rotating body 60 is rotatable relative to the rotating member 50. The rotary body 60 is formed with a key hole 61 into which the shaft of the key bundle 230 is inserted. The key hole 61 is formed complementarily with the shaft of the key bundle 230. When the key is put into the key hole 231 of the key bundle, the shaft rotates the rotating body 60. The rotating body 60 has the pressing part 62 which protruded in the radial direction of the rotating body.

The locking member 70 is coupled to the rotating member 50 to rotate together with the rotating member 50 when the rotating member 50 rotates. The locking member 70 includes a rotating part 72 rotatably coupled to the rotating member 50 about the pivot shaft 71, and a protrusion 73 protruding from the rotating part 72 in the thickness direction of the door 2. Has The locking member 70 is rotatable between the locking position and the unlocking position. When the locking member 70 is located at the locking position as shown in FIG. 3, the protrusion 73 of the locking member is disposed on the rotation path of the handle pin 240. 3, when the handle pin 240 is rotated clockwise in a state where the locking member 70 is located at the locking position, the protrusion 73 is pressed by the handle pin 240. The rotating member 50 is rotated clockwise together with the locking member 70. And as shown in Figure 4 by the rotation of the rotating member 50 is moved in the direction in which the dead bolt 20 is immersed to unlock the door (2). On the other hand, when the locking member 70 is located in the unlocking position as shown in Figure 2, the locking member 70 is disposed to move away from the rotation path of the handle pin 240, the handle pin 240 in the clockwise direction Rotating member 50 does not rotate even when rotated to, the handle pin 240 is rotated in the insertion through portion (512).

The locking member 70 is connected to the rotating body 60 via a pressure member 80 to be described later. Therefore, when the rotation of the rotating body 60 in one direction, for example clockwise rotation, the pressing member 80 is linearly moved, the locking member 70 is interlocked with the linear movement of the pressing member 80 It moves from the unlocking position to the locking position.

The locking member 70 is elastically biased in the direction away from the rotation path of the handle pin 240 by the compression coil spring (74). One end of the compression coil spring 74 is fixed to the locking member 70, and the other end of the compression coil spring 74 is fixed to the case 11.

The pressing member 80 is inserted into the slot 131 of the cover, the sliding pin portion 81 which is slidable in the longitudinal direction of the slot 131, and is connected to the sliding pin portion 81, the arc-shaped contact surface 821 is A second pressing portion 83 connected to the first pressing portion 82 and the sliding pin portion 81 formed in an “L” shape and pressed by the pressing portion 62 of the rotating body at the pressing position; The press part 84 connected to the pin part 81 is provided. The center of curvature of the contact surface 634 is located at the center of rotation of the rotating member 50 when the pressing member 63b is positioned at the pressing position. The contact surface 821 of the first pressing portion presses the protrusion 73 of the locking member in the pressing position.

The pressing member 80 is installed in the housing 10 to enable linear movement between the pressing position shown in FIG. 3 and the pressing release position shown in FIG. 2. When the pressing member 80 is located at the pressing position, the contact surface 821 of the pressing member contacts and presses the protrusion 73 of the locking member, thereby positioning the protrusion 73 at the locking position. When the pressing member 80 is positioned at the release position, the contact surface 821 of the pressing member does not come into contact with the protruding portion 73 of the locking member, and the pressure on the protruding portion 73 of the contact surface 821 is released. The locking member 70 is positioned at the release position. When the rotating body 60 rotates in one direction, that is, the clockwise direction, the pressing portion 62 of the rotating body presses the second pressing portion 83 of the pressing member so that the pressing member 80 is positioned at the pressing position. In the process of moving the pressing member 80 to the pressing position, the contact surface 821 of the pressing member contacts the protrusion 73 of the locking member to press the protrusion 73 to thereby increase the elastic force of the compression coil spring 74. Overcome, the protrusion 73 of the locking member is located in the locking position.

In addition, the cover 13 has a pair of stopper members 86 for fixing the position of the pressing member when the pressing member 80 in the pressing position or the release position. The pair of stopper members 86 are arranged to face each other with the slot 131 therebetween as shown in FIG. 5B. Each stopper member 86 is a protrusion 861 formed to be spaced apart from each other by a predetermined interval, and the first groove 862 and the first recessed portion 862 and the recessed pin portion 81 of the pressing member which is formed concave in each protrusion 861 can be inserted and fixed It has two grooves 863. Each stopper member 86 is made of an elastically deformable material and is elastically deformable in a direction crossing the linear movement direction of the pressing member 80. In this embodiment, each stopper member 86 is comprised of a leaf spring.

In the state where the pressing member 80 is located in the pressure release position shown by the solid line in FIG. 5B, the sliding pin part 81 of the pressing member is inserted into the 1st groove part 862 of each stopper member, and the position is fixed. In this state, when the pressing member 80 is slid to the left, the sliding pin portion 81 of the pressing member presses the protrusion 861 of each stopper member in the moving process so that each stopper member 80 is elastically deformed and simultaneously pressed. The sliding pin portion 81 of the member is located at the pressing position shown by the virtual line in FIG. 5B. Then, in the pressing position, the sliding pin portion 861 of the pressing member is inserted into the second groove portion 863 of each stopper member to fix its position.

Meanwhile, the mortise portion 300 further includes a moving member 90 and a motor 94.

The moving member 90 is installed in the housing 10 to be linearly movable. The moving member 90 is provided with a main body 91, a rack portion 92, and a pair of protrusions 93. The rack 92 is formed long in the moving direction of the moving member 90 on one side of the main body 91. The pair of protrusions 93 protrude from the main body in a direction intersecting with the moving direction of the moving member 90, and in particular, protrude in a direction perpendicular to the moving direction of the moving member. The pair of protrusions 93 are arranged to be spaced apart at regular intervals in the moving direction of the moving member 90. Between the pair of protrusions 93, the pressing portion 84 of the pressing member is disposed. When the moving member 90 moves, the pressurized portion 84 is pressed by any one of the pair of protrusions 93 so that the pressing member 80 moves linearly. In addition, the separation distance between the pair of protrusions 93 is formed such that the pressurized portion 84 does not come into contact with the protrusions 93 when the pressing member 80 moves between the pressing position and the release position.

The motor 94 is provided inside the housing 10. The motor 94 is capable of forward and reverse rotation, and the pinion 95 is coupled to the output shaft of the motor. The pinion 95 is gear-coupled to the rack portion 92 of the movable member. In the present embodiment, the pinion 95 and the rack portion 92 are directly engaged.

In the door lock device 1 configured as described above, an example of a process of releasing the locking of the door 2 in the indoor side and the outdoor side will be described.

First, in order to release the locked state of the door 2 as shown in FIG. 2 indoors, when rotating the knob 120 installed in the room clockwise, the rotary pin 130 with the handle 120 This will rotate clockwise. In the course of the rotation of the rotary pin 130, the rotary pin 130 is to press the inner wall of the fitting through portion 513 to rotate the rotating member 50 in the clockwise direction. In addition, since the pressing part 53 of the rotating member is caught by the locking jaw 31 of the intermediate member and presses the intermediate member 30 during the rotation of the rotary member 50, the intermediate member 30 linearly moves to the right. Done. In addition, since the dead bolt 20 also moves in the direction immersed in the housing 10 as the intermediate member 30 moves, the locking of the door 2 is released. As such, in the room, the locking of the door 2 can be easily released by simply rotating the handle 120.

Next, in order to release the locking state of the door shown in FIG. 2 outdoors, when a predetermined number is input to the number input unit 211 and authenticated, the motor 94 rotates forward to move the moving member 90 in FIG. 2. In the state shown in the to move to the left. In the process of moving the movable member 90, the protrusion 93 of the movable member comes into contact with the pressable portion 84 of the pressurizing member to press the pressurized portion 84 to thereby press the pressurizing member 80. It can be located in the pressing position shown in. In the process of moving the pressing member 80, the contact surface 821 of the pressing member presses the protrusion 73 of the locking member so that the protrusion 73 of the locking member is positioned at the locking position shown in FIG. 3. As such, when the handle 220 is rotated in the state where the protrusion 73 of the locking member is located at the locking position, the handle pin 240 rotates together with the handle 220 to rotate the handle pin 240 shown in FIG. 4. It can be located in the second position. In addition, the handle pin 240 presses the protrusion 73 of the locking member during the rotation of the handle pin 240, so that the rotating member 50 rotates clockwise along with the handle pin 240. At this time, since the center of curvature of the contact surface 821 is located on the central axis of rotation of the rotating member 50, the protrusion 73 of the engaging member is relatively slid while contacting the contact surface 821 of the pressing member. When the rotation member 50 rotates in the clockwise direction as described above, the locking of the door 2 is released as described above. On the other hand, if the authentication is not received, the protrusion 73 of the locking member is not located at the locking position, even if the handle 220 is rotated, the rotating member 50 is not rotated so that the locking of the door 2 is maintained. .

In addition, in order to release the locking of the door 2 shown in FIG. 2 on the outdoor side in an emergency where the motor 94 cannot be operated, the key is inserted into the key hole 231 of the key bundle and rotated. The rotating body 60 can be rotated in the clockwise direction by the shaft. As described above, when the rotating body 60 rotates in the clockwise direction, the pressing part 62 of the rotating body presses the second pressing part 83 of the pressing member to move the pressing member 80 to the left side. It can be located in the pressing position shown in. In the process of moving the pressing member 80, the contact surface 821 of the pressing member contacts the protrusion 73 of the locking member to press the protrusion 730, so that the locking member 70 is caught in FIG. 3. Then, the handle pin 240 is rotated to place the handle pin 240 at the second position shown in FIG. 4, and the handle pin 240 is rotated in the process of rotating the handle pin 240. As the protrusion 73 of the locking member is pressed to rotate the rotating member 50 in the clockwise direction, the locking of the door 2 is released as described above.

On the other hand, even when the handle 220 or the handle 120 is rotated and the door 20 is unlocked, even if the handle 220 or the handle 120 is released, the dead bolt 20 has a well-known protrusion prevention structure. When the door 2 is opened and closed, the dead bolt 20 automatically protrudes and locks the door by a known locking means. Since the locking means is already widely known as disclosed in Korean Patent Application No. 2006-92486, the detailed description of the structure will be omitted here.

As described above, in the present embodiment, it is possible to release the locking of the door 2 only by rotating the handle 120 in the room, so in case of emergency, for example, in case of fire or earthquake, Even if the person on the side is mentally panic, the handle 120 can be easily rotated to escape. Therefore, it is possible to minimize human injury.

In addition, in the present embodiment, after the authentication is performed from the number input unit 211, the door 240 can be released by rotating the handle 240, and the door is locked by the driving of the motor. Unlike the automatic system which is released, since it is semi-automatically constructed, the durability of the door lock apparatus 1 increases. The motor 94 is not configured to directly move the dead bolt, but is configured to move the pressing member 80, so that a motor having a smaller output than the conventional one can be used. It is also possible to reduce power consumption.

6 is a partial cross-sectional view schematically showing the internal structure of the mortise according to the second embodiment of the present invention, Figure 7 is a schematic view showing a state in which the pressing member shown in Figure 6 is pressed by the rotating body in the pressing position The figure shown.

6 and 7, in the mortise portion 300a of this embodiment, the pressing member 80a is rotatably installed between the pressing position and the pressing release position. The pressing member 80a has a pivot shaft 81a coupled to the cover 13, and the pressing member 80a is rotatable about the pivot shaft 81a. The first pressing portion 82a, the second pressing portion 83, and the pressed portion 840 of the pressing member are connected to the pivot shaft 81a.

It is preferable that the 1st press part 82a is elastically deformable. In order to enable the first pressing part 82a to be elastically deformable, the first pressing part 82a may be formed of an elastically deformable material or may be configured to include a plurality of components such that the first pressing part 82a may be elastically deformable. Just do it. For example, the first pressing part 82a may be made of an elastically deformable material such as a leaf spring or rubber. In addition, the first pressing portion 82a is configured to include a pair of rigid bodies, and elastic members such as leaf springs and compression coil springs that connect the pair of rigid bodies, The one press part 82a can be comprised so that elastic deformation is possible. In this embodiment, the first pressing portion 82a is formed of a leaf spring. The first pressing portion 82a has an elastic force such that it is not elastically deformed by the protrusion 73 when pressing the protrusion 73 of the locking member in the pressing position.

Also in the door lock apparatus 1a comprised as mentioned above, like the door lock apparatus 1 demonstrated while referring FIG. 1 thru | or 5B, the locking of the door 2 can be released. However, when releasing the locking of the door 2 by the operation of the motor 94 or the rotation of the rotating body 60, the pressing member 80a is rotated about the pivot shaft 81a to be locked from the unlocking position. The only difference is that they are located in position.

On the other hand, when the handle 220 is rotated and then released to unlock the door, the handle 220 is returned to its original state by the elastic restoring force of the torsion spring (not shown). However, when the door lock device is used for a long time, the elastic restoring force of the torsion spring is reduced so that even when the handle 220 is released, the handle pin 240 does not return to the original position shown as a virtual line in FIG. Sometimes it will only happen to be located. As such, when the handle pin 240 is restored only to the position shown by the solid line in FIG. 7, the pressing member 80a and the locking member 70 are respectively driven by the driving of the motor 94 or the rotation of the rotating body 60. Even if the handle pin 240 is rotated after the pressing position and the locking position, the handle pin 240 cannot press the protrusion 73 of the locking member, so that the locking of the door 2 cannot be released.

However, as in this embodiment, the first pressing portion 82a is configured to be elastically deformable, so that the pressing portion 62 of the rotating body is shown in FIG. 7 as the second pressing portion 82a of the pressing member. When the handle pin 240 shown in solid line in FIG. 7 is rotated counterclockwise while pressing), the protrusion 73 of the engaging member is handle pin 240 as shown in FIG. Pressed by) to rotate in a counterclockwise direction about the pivot shaft 71. During the rotation process, the first pressing portion 82a is pressed by the protrusion 73 of the engaging member to elastically deform, and thus the handle pin. 240 may be positioned at the position shown in phantom in FIG. 7. As such, when the handle pin 240 is positioned at the position shown by the virtual line in FIG. 7, the second pressing part 83 and the protrusion 73 of the locking member may be formed by the elastic restoring force of the first pressing part 82a. Since it is again located at the position shown by the solid line in Figure 7, it is possible to release the locking of the door (2) during the rotation of the handle pin 240 in the clockwise direction.

8 is a partial cross-sectional view schematically showing the internal structure of the mortis according to the third embodiment of the present invention, Figure 9 is a schematic view showing a state in which the pressing member shown in Figure 8 is pressed by the rotating body in the pressing position The figure shown.

8 and 9, in the mortise portion 300b of this embodiment, the pressing portion material 80b is rotatably provided between the pressing position and the pressing release position.

The pressing member 80b has a pivot shaft 81b coupled to the cover 13, and the pressing member 80b is rotatable about the pivot shaft 81b. The first pressing portion 82, the second pressing portion 83b, and the pressed portion 84 of the pressing member are connected to the pivot shaft 81b. It is preferable that the second pressing portion 83b is elastically deformable. In order to allow the second pressing portion 83b to be elastically deformable, the second pressing portion 83b is formed of an elastically deformable material or configured to include a plurality of components such that the second pressing portion 83b is elastically deformable. Just do it. For example, the second pressing part 83b may be made of an elastically deformable material such as a leaf spring or rubber. In addition, the second pressing portion 83b is configured to include a pair of rigid bodies and elastic members such as leaf springs and compression coil springs that connect the pair of rigid bodies, The two pressing parts 83b can be configured to be elastically deformable. In this embodiment, the second pressing portion 83b is formed of a leaf spring. The second pressing portion 83b has an elastic force such that the pressing portion 62 does not elastically deform when the pressing portion 62b is pressed by the pressing portion 62 of the rotating body at the pressing position.

Then, the pressing member 80b is elastically biased to rotate to the pressing release position when the pressing member 80b is positioned at the pressing position by the compression coil spring 85. One end of the compression coil spring 85 is fixed to the moving member 90b, and the other end of the compression coil spring 85 is fixed to the pressure member 84. The moving member 90b includes a main body 91 and a rack portion 92. The pinion 95 is engaged with the rack portion 92, and the pinion 95 is connected to a deceleration portion (not shown) including a reduction gear, so that the second pressing portion 83b of the pressing member is shown in FIG. 9. As shown, even when pressed by the pressing part 62 of the rotating body, the moving member 90b does not move.

Also in the door lock apparatus 1b comprised as mentioned above, like the door lock apparatus 1 demonstrated while referring FIG. 1 thru | or 5B, locking of the door 2 can be released. However, when the door is unlocked by the operation of the motor or the rotation of the rotating body, the pressing member 80b is rotated about the pivot shaft 81b so that the motor is positioned from the unlocking position to the locking position. When the moving member 90 is moved by the rotation of 94, there is only a difference in that the pressing member 80 is rotated by the elastic force of the compression coil spring 85 so as to be positioned at the pressing position or the releasing position.

In addition, as described with reference to FIGS. 8 and 9, even when the handle pin 240 is positioned only to the position shown by the solid line in FIG. 9 by using the door lock device for a long time, the handle pin 240 may be simulated in FIG. 9. The door is unlocked by returning to the position shown by the line. To do this, you can do as follows: When the pressing part 62 of the rotating body rotates the handle 220 counterclockwise in the state which presses the 2nd pressing part 83b of the pressing member, as shown in FIG. 7, an imaginary line is shown in FIG. As shown in the drawing, the protrusion 73 of the locking member is pressed by the handle pin 240 to rotate in a counterclockwise direction about the pivot shaft 71, and in the process of rotating the protrusion 73 of the locking member. Since the first pressing portion 82 of the pressing member is pressed by the projecting portion 73 of the locking member, the second pressing portion 83b of the pressing member is elastically deformed as shown in FIG. 9 by an imaginary line. The first pressing portion 82 and the pressing portion 84 of the pressing member rotate clockwise about the pivot axis 81b, so that the handle pin 240 is positioned at the position shown in phantom in FIG. You can do it. As such, when the handle pin 240 is positioned at the position shown by the imaginary line in FIG. 9, the first pressing part 82, the pressurized part 84, and the locking part are caught by the elastic restoring force of the second pressing part 83b. Since the protrusion 73 of the member is positioned again at the position shown by the solid line in FIG. 9, the locking of the door 2 can be released when the handle pin 240 is rotated in the clockwise direction.

10 is a partial cross-sectional view schematically showing the internal structure of the mortis according to the fourth embodiment of the present invention.

Referring to Fig. 10, in the mortise portion 300c of the present embodiment, a tooth portion 62c having a plurality of teeth is formed on the outer circumferential surface of the rotating body 60c. The moving member 90b includes a main body 91 and a rack portion 92. Pinions 63 are geared to the teeth 62c of the rotating body and the racks 92 of the movable member 90c, respectively. The pivot shaft 631 of the pinion 63 is coupled to the housing 10. Therefore, the pinion 63 is rotated not only at the time of rotation of the motor 94 but also by the rotation of the rotor 60c, and the movable member 90c can be linearly moved. The pressing member 80c includes a pivot shaft 81c, a first pressing portion 82, and a pressing portion 84. The pressing member 80c is rotatable about the pivot shaft 81c and can be changed in position between the pressing position and the pressing release position. Then, the pressing member 80c is elastically biased to rotate to the pressure release position when the pressing member 80c is positioned in the pressing position by the compression coil spring 85 as shown in FIG. One end of the compression coil spring 85 is fixed to the moving member 90c, and the other end of the compression coil spring 85 is fixed to the pressure member 84.

Also in the door lock apparatus 1c comprised as mentioned above, like the door lock apparatus demonstrated with reference to FIGS. 1-5B, the locking of the door 2 can be released. However, when the moving member (90c) is moved by the rotation of the motor 94, the difference in that the pressing member (80c) is rotated by the elastic force of the compression coil spring 85 is located in the pressing position or the pressure release position. There is. In addition, when the pinion 63 rotates while the rotating body 60c rotates, the moving member 90c moves, and the pressing member 80c moves to the virtual line in FIG. 10 by the elastic force of the compression coil spring 85. There is also a difference in that it is located in the pressing position by rotating as shown.

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.
