The present invention relates to a door lock device, and more particularly to a door lock device for locking and unlocking the door.

In general, the door lock device is widely used in general home houses or public buildings. Typically, door locks are used for entrance doors, bank vaults, and access controls to restrict access to specific areas.

Such a door lock device generally includes a housing installed in the door, a latch bolt protruding and immersed in the housing, and a dead bolt for locking and unlocking the door as it protrudes and immerses in the housing. The latch bolt is formed with a curved curved portion so as to move in the direction in which the latch bolt is immersed in contact with the door holder when the door is closed. Then, the dead bolt is driven by the rotation of the motor to lock and unlock the door. In addition, when the door is closed, the sensing unit installed in the door detects the magnetic unit installed in the door holder to generate a detection signal, and the motor is driven by the detection signal to automatically lock the door.

In addition, a button for operating a motor and a rotatable handle are coupled to an indoor side of the door, and an authentication unit such as a number input unit for operating a motor, a fingerprint recognition unit, and a rotatable handle are installed on an outdoor side of the door. Therefore, in order to open and exit the door from the indoor side, press the button to operate the motor, and then open the door by turning the handle.In order to open and enter the door from the outdoor side, for example, enter the preset number to operate the motor. Turn the knob to open the door. As a result, the user turns the handle or the handle as the secondary operation after the primary operation for moving the dead bolt to open the door, for example, inputting a number or pressing a button.

By the way, in the door lock apparatus comprised as mentioned above, since the deadbolt is driven so that it may protrude and be immersed by the output of a motor, only the motor whose output is more than a predetermined amount should be used. In addition, when the dead bolt is disturbed, such as the dead bolt is jammed, the phenomenon that the motor is overloaded and often breaks the motor often occurs. In addition, an impact is generated in the dead bolt in the process of opening and closing the door, and the impact is transmitted to the output shaft of the motor driving the dead bolt, so that a failure occurs frequently in a motor that is weak in impact.

In addition, in an emergency, for example, in the event of a fire or an earthquake, the person in the room is mentally panicked, and thus, the door cannot be released by pressing the button. It is a secondary action, just turning the handle. Therefore, there is a problem in that the locking of the door is not released and a person on the indoor side is trapped, resulting in human injury.

The present invention has been made to solve the above problems, an object of the present invention is to improve the structure of the door lock to reduce the power consumption and durability, as well as to easily release the locking of the door in the emergency room in the emergency To provide a device.

In this embodiment, the locking member 61 is rotatably coupled around the pivot shaft 611. The locking member 61 is rotatable between the locking position and the unlocking position. When the locking member 61 is located at the locking position as shown in FIG. 4, the locking member 61 is disposed on the rotation path of the handle pin 240. In addition, as shown in FIG. 4, when the handle pin 240 is rotated in one direction, that is, in a clockwise direction while the locking member 61 is located at the locking position, the locking member 61 is connected to the handle pin 240. Since it is pressurized, the rotating member 50 is rotated in one direction. And as shown in Figure 3 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 61 is located in the unlocking position as shown in Figure 2, since the locking member 61 is disposed to deviate from the rotation path of the handle pin 240, the handle pin 240 in one direction Even if rotated, the rotating member 50 does not rotate, the handle pin 240 is rotated in the insertion through portion 504.

The locking member 61 is elastically biased in the direction away from the rotation path of the handle pin 240 by the tension coil spring 62. One end of the tension coil spring 62 is fixed to the locking member 61, and the other end of the tension coil spring 62 is fixed to the case 11.

The pressing member 63 is installed in the housing 10 so as to be linearly movable. The pressing member 63 is movable between the pressing position and the pressing release position. When the pressure member 63 moves from the pressure release position shown in FIG. 2 to the pressure position shown in FIG. 4, the pressure member 63 pressurizes the catching member 61 in the moving process so that the tension coil spring 62. Overcoming the elastic force of the locking member 61 is disposed on the rotation path of the handle pin 240. Then, when the pressing member 63 returns to the pressure release position shown in FIG. 2 again, the pressing member 63 of the pressing member 63 is released in the returning process, and the tension coil spring 62 The locking member 61 is moved away from the rotation path of the handle pin 240 by the elastic restoring force. The pressing member 63 is formed with a rack 631. The rack 631 is formed long in the moving direction of the pressing member 63.

The motor 64 is installed inside the housing 10. The pinion 641 is coupled to the output shaft of the motor 64, and the pinion 641 is gear-coupled with the rack 631 of the pressing member. In particular, in this embodiment, the pinion 641 and the rack 631 are directly engaged. The motor 64 drives the urging member 63 such that the urging member 63 is movable between the urging position and the urging release position. The motor 64 is capable of forward and reverse rotation, for example, the pressurizing member 63 located at the regular display press release position of the motor 64 is positioned at the pressurizing position, and the pressurizing member is pressurized during the reverse rotation of the motor 64. From the position to the pressure release position. When a preset number is input to the number input unit 211 provided on the outdoor side, the motor 64 operates. At this time, the motor 64 is rotated forward to position the pressing member 63 to the pressing position, and after a predetermined time, for example, after about 4 to 5 seconds, the motor 64 is rotated back to the pressure release position. Position it. In addition, even before 5 seconds have elapsed, the moment when the handle pin 240 presses the pressing member 63 is sensed by a separate sensor (not shown). Then, at the moment detected by the sensor, the motor 64 is reversely rotated so that the pressing member 63 is positioned at the pressure release position.

The rotating pin 130 is inserted into the fitting through portion 505. The rotary pin 130 may rotate around the central axis of rotation of the rotating member 50 about the central axis of rotation. In the state shown in FIG. 2, when the rotating pin 130 rotates in the clockwise direction, the rotating pin 130 presses the inner wall of the fitting through part 505 to rotate the rotating member 50 in one direction.

The anti-rotation member 70 is rotatably coupled to the pivot shaft 71 inside the housing 10. The anti-rotation member 70 is rotatable between the free rotation position shown by the solid line in FIG. 6 and the anti-rotation position shown by the virtual line in FIG. 6. When the anti-rotation member 70 is located at the free rotation position, the anti-rotation member 70 is disposed to be spaced apart from the rotation path of the handle pin 240 so that the handle pin 240 is free to rotate from the first position to the second position. It becomes possible. On the other hand, when the anti-rotation member 70 is located in the anti-rotation position, the handle pin 240 is caught by the anti-rotation member 70 to prevent the handle pin 240 from rotating from the first position to the second position. The anti-rotation member 70 is driven by a motor (not shown) installed inside the housing 10.

Protruding length adjustment member 80 is coupled to the housing 10 to be linearly movable in a direction orthogonal to the moving direction of the dead bolt (20). The protruding length adjusting member 80 protrudes the dead bolt by limiting the movement of the dead bolt 20 when the dead bolt 20 protrudes with respect to the housing 10 while the door 2 is unlocked. Adjust the length. The protruding length adjusting member 80 is disposed on a straight line moving path of at least one of the dead bolt 20 and the intermediate member 30 when adjusting the protruding length of the dead bolt 20. In the present embodiment, one protrusion length adjusting member 80 is disposed on the linear movement path of the intermediate member 30 when adjusting the protrusion length of the dead bolt. The protruding length adjusting member 80 may be positioned between an adjusting position as shown in FIG. 5 and a spaced position as shown in FIG. 2. When the protruding length adjusting member 80 is located at the adjusting position, the dead bolt 20 is moved by the protruding length adjusting member 80 to the intermediate member 30 when the dead bolt 20 moves in a direction protruding with respect to the housing 10. 20 does not fully protrude. Thus, the protruding length of the dead bolt 20 is reduced. On the other hand, when the protruding length adjusting member 80 is located at a spaced position, the protruding length adjusting member 80 is disposed to be out of the moving path of the intermediary member 30 and thus does not prevent the linear movement of the intermediary member 30. In addition, the protruding length adjusting member 80 may be configured to protrude in the indoor housing 110 to move linearly by pressing.

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 as shown in FIG. 2 indoors, when the handle 120 installed in the indoor side is rotated, the rotation pin 130 rotates together with the handle 120. In the rotation process of the rotary pin 130, the rotary pin 130 presses the inner wall of the fitting through portion 505 so that the rotary member 50 rotates in one direction, that is, clockwise. In addition, since the engaging portion 502 of the rotating member is caught by the locking jaw 31 of the intermediate member and presses the intermediate member 30 in the rotation process 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 the preset number is input to the number input unit 211 and authenticated, the motor 64 is rotated forward and the pressing member 63 is rotated. Located in the pressing position shown in the, the pressing member 63 in the process of the movement to press the locking member 61 finally the locking member 61 is located in the locking position shown in FIG. As such, when the handle 220 is rotated in a state where the locking member 61 is located at the locking position, the handle pin 240 rotates together with the handle 220 to rotate the handle pin 240 as illustrated in FIG. 3. To be located at the location. In addition, the handle pin 240 is pressed by the locking member 61 in the process of rotating the handle pin 240, the rotation member 50 together with the handle pin 240 is rotated in one direction. As the rotation member 50 rotates in one 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 locking member 61 is not located in the locking position, the locking of the door 2 is continuously maintained.

In addition, in the event that the motor 64 fails, the key is inserted into the key hole 231 of the key insertion member and the key hole 511 of the key bundle to release the door 2 from the outside. Just do it.

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 64 is not configured to directly move the dead bolt, but is configured to move the pressing member 63, so that a motor having a smaller output than the conventional one can be used. It is also possible to reduce power consumption.

On the other hand, in the first embodiment is configured to be semi-automatic to release the lock of the door by rotating the handle pin or the rotary pin after the user obtains the number authentication, as shown in Figure 7 and 8 It can also be configured to automatically unlock the door only by. In the present embodiment, the same components as the first embodiment are indicated with the same reference numerals and slightly changed, but corresponding components are indicated with the addition of 'a', and the description of the same parts as in the first embodiment will be omitted. Only the other parts will be described.

The mortise portion 300a according to the present embodiment has a housing 10, a dead bolt 20, an intermediate member 30, and rotation similarly to the mortise portion 300 of the door lock device described with reference to FIGS. 1 to 6. It has a member 50a.

The driving member 506 is formed in the rotating member 50a. The drive protrusion 506 protrudes from the outer circumferential surface of the disc portion 501.

The rotation driving means includes a pressing member 63a and a motor 64.

The pressing member 63a is installed in the housing 10 so as to be linearly movable. The first pressing protrusion 632 and the second pressing protrusion 633 are formed in the pressing member 63a. The first pressurizing protrusion 632 and the second pressurizing protrusion 633 are disposed to face each other. As shown in FIG. 7, the driving protrusion 506 is disposed between the first pressing protrusion 632 and the second pressing protrusion 633. In addition, a rack 631 is formed in the pressing member 63a. The rack 631 is formed long in the moving direction of the pressing member 63a.

The motor 64 is connected to the pressing member 63a to drive linear movement of the pressing member 63a. The motor 64 is capable of forward and reverse rotation. The pinion 641 is coupled to the output shaft of the motor 64, and the pinion 641 is gear-coupled with the rack 631. In this embodiment, the pinion 641 and the rack 631 are directly engaged.

As shown in FIG. 7, when the motor 64 rotates forward with the door 2 locked, the pressing member 63a moves to the left while the first pressing protrusion 632 moves the driving protrusion 506. Press to rotate the rotating member (50a) clockwise. Thus, the locking of the door 2 is released. On the other hand, when the motor 64 rotates in the reverse state while the door 2 is unlocked, the pressing member 63a returns to its original position, and in the process, the second pressing protrusion 633 opens the driving protrusion 506. By pressing, the rotating member 50 is rotated counterclockwise. Then, since the dead bolt 20 protrudes by the elastic restoring force of the compression coil spring, the door 2 is locked again. In addition, the rotating member 50 is elastically biased by a torsion spring (not shown), so that the rotating member 50 can be rotated in the counterclockwise direction more easily. As described above, in this embodiment, the door 2 can be locked and unlocked by driving the dead bolt 20 by the forward and reverse rotation of the motor 64.

In the door lock device of the present embodiment, the handle and the handle are not provided at the indoor side and the outdoor side, respectively. That is, the indoor side includes an indoor housing and an operation button for operating a motor, and the outdoor side includes an outdoor housing and an authentication unit such as a number input unit.

Meanwhile, in the first embodiment, the pressing member is configured to return to the press release position again when the handle pin is rotated. However, when the pressing member is configured as shown in FIGS. 9 to 12, the pressing member is pressed even when the handle pin is rotated. It can be positioned as it is.

In the present embodiment, the same components as the first embodiment are indicated with the same reference numerals and slightly changed, but the corresponding components are indicated with the addition of 'b', and the description of the same parts as the first embodiment will be omitted since they are duplicated. Only the other parts will be described.

In the mortise portion 300b of the present embodiment, the locking member 61b is formed on the rotating portion 612 rotatably coupled to the rotating member 50 and the rotating portion 612 to protrude in the thickness direction of the door 2. It has a protrusion 613. As shown in FIG. 12, the rotating part 612 is disposed to be spaced apart from the disk part 501 of the rotating member by a predetermined distance. The protrusions are also spaced apart from the disc portion 501.

An arc-shaped contact surface 634 is formed on the pressing member 63b. 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. When the pressing member 63b is located at the pressure release position, the contact surface 634 does not contact the locking member 61b. When the pressing member 63b moves from the press release position to the pressing position, the contact surface 634 contacts the locking member 61b to press the locking member 61b to the locking position.

On the other hand, to unlock the door outdoors in the state in which the door 2 is locked as shown in FIG. Position it in a pressurized position together. At this time, the contact surface 634 maintains contact with the protrusion 613 of the locking member. Thereafter, when the handle pin 240 is rotated, the handle pin 240 presses the locking member 61b so that the rotation member 50 rotates in one direction, that is, clockwise direction. At this time, since the center of curvature of the contact surface 634 is located on the central axis of rotation of the rotating member 50, the protrusion 613 of the locking member slides relative to the contact surface 634 of the pressing member. Then, a predetermined interval is formed between the locking member 61b and the rotating member 50, so that the pressing member 63b is not caught by the locking member 61b when the rotating member 50 is rotated.

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.

According to the present invention of the above-described configuration, the door lock device is semi-automatically configured to improve durability compared to the prior art. In addition, it is possible to easily release the locking of the door simply by turning the handle, it is possible to easily escape in an emergency to minimize the occurrence of human injury. In addition, it is possible to use a motor with a small output can reduce power consumption.
