Description

Door lock device

The present invention relates to a door lock device, and more particularly, to a door lock device that allows to open or close a specific space, such as entrance doors, car doors and safes.

The door lock device is widely used as being configured to open or close a specific space such as a door of a house, a safe, a door of a vehicle, and the like. Such door lock devices are widely used in general homes or public buildings, and are typically used as entrance control devices for restricting access to entrance doors, bank vaults and specific areas. Recently, a digital door lock device that can lock and unlock a door by linearly moving a clamp by operating a motor or a solenoid after authenticating a user through a password input or a fingerprint recognition method has been widely used.

Figure 1 shows a digital door lock device in the form of a so-called auxiliary key that does not include a handle. Referring to FIG. 1, the digital door lock device 100 ′ includes a housing 10 ′ coupled to the interior side of the door 1, and a cap member 70 ′ coupled to the door post while moving in a direction protruding and immersing into the housing. And a lock 20 'for locking and unlocking the door as it is inserted into and released from the door. A stopper portion 21 'is formed at the stopper 20', and the stopper portion 21 'is caught by a part 13' protruding from the inner side of the housing 10 'with the door locked. 20 ') no longer moves in a protruding direction relative to the housing 10'. In addition, the clasp 20 'is a drive including a motor (not shown) installed inside the housing 10' and a keypad installed at an outdoor side of the door and generating a signal for authenticating the user and generating a signal for operating the motor upon user authentication. Driven by means. The driving means is rotatably coupled to the housing and is connected to the output shaft of the motor and includes a pressing member 61 ′ that rotates when the motor rotates and interlocks with the rotation to pressurize and lock the clamp 20 '.

On the other hand, in recent years, attempts have been frequently attempted to physically hack the digital door lock device. For example, attempts have been made to physically hack a digital door lock device by breaking the door by inserting a so-called 'Paru' into the gap between the door and the door holder. For reference, 'Paru' refers to a tool made of a metal material and formed long in one direction and having a groove formed at an end thereof to remove a nail.

By the way, in the digital door lock device configured as described above, due to the structural limitation that the clasp cannot protrude from the housing even if a slight physical hacking attempt is made, the clasp 20 'and the protruding portion 13' of the housing, etc. There was a problem that is broken. That is, since the clasp 20 'can no longer protrude when the door is locked, breakage of the clasp and the like can not be avoided when the clasp 20' further protrudes even a little. In general, when physically hacking by 'Paru', the process of flipping the door should be repeated repeatedly, but in the conventional digital door lock device, even if the door is only flipped once, the clamp and the like are damaged.

In addition, in the above-described digital door lock device, it is very vulnerable to physical hacking because there is no configuration that detects a physical hack to sound an alarm or informs the security company of a physical hack so that the security guard can be dispatched immediately. There is a limit.

In addition, in the above-described physical hacking attempt, the door 1 must be deformed as shown in FIG. 7, so that the housing 10 ′ of the door lock device installed in the door also retreats by the deformed amount. do. In particular, the catch 20 'is configured to contact the stopper portion 21' of the housing so that the catch also retracts by the amount of deformation of the door. Therefore, the length of the catch 20 'protruding from the side of the door 1 is reduced after physical hacking. When the protruding length of the catch 20 'is reduced in this way, since the position of the cap member 70' does not change, the catch 20 'may not be inserted into the cap member. In this way, if the protruding length of the clamp 20 'is reduced so that it is not inserted into the cap member, even if the door lock device is excellent in durability due to the durability of the door lock device, the locking state of the lock device is not maintained. do. In other words, in the conventional door lock device, if the gap between the door and the door holder is further opened by physical hacking, the protruding length of the catch 20 'does not increase by the gap, so that the catch 20' is a cap member. There was a problem that the security of the door lock device could not be secured because it was not inserted into the insertion hole 71 'of 70'. Therefore, when the door is deformed by physical hacking, there is a need for a door lock device configured to increase the protruding length of the clamp 20 'by at least the deformed width.

The present invention has been made to solve the above problems, the object of the present invention is not only to improve the durability and security of physical hacking, but also to physically hack attempts can be initially blocked by the physical hacking attempts can be immediately blocked. It is to provide a door lock device with an improved structure.

In order to achieve the above object, the door lock device according to the present invention is coupled to the door, the through-hole housing through; A locking release position coupled to the housing so as to be movable relative to the housing through the through hole, the locking position of the door being locked and the locking release position of the door being unlocked by moving in a direction immersed with respect to the housing from the locking position. A lock which is selectively positioned at and movable in a predetermined reference distance in a protruding direction with respect to the side of the door facing the door jammer in the locking position; And an elastic force coupled to the housing so as to be pressed by the catch when moving from the locking position of the catch to the side of the door to move the catch in a direction immersed with respect to the side of the door. It characterized in that it comprises an elastic member for generating.

And the door lock device according to another aspect of the present invention comprises a housing coupled to the door; The door is coupled to the housing so as to be movable in a direction protruding and immersed with respect to the housing, the door protruding with respect to the housing and moving in a direction immersed with respect to the housing from the locking position and the locking position. A lock which is selectively positioned at a unlocking position to be unlocked, the lock being positioned at a hacking position that protrudes further with respect to the housing than at the locking position; And a latching position that is caught by the catch so that the movement of the catch in the immersive direction is prevented, and a catch release position where the catch with the catch is released to allow movement of the catch in the protruding and immersive directions. And a locking member coupled to the housing such that the locking member is pressed by the locking key and moved to the locking position when the locking key is moved from the locking position to the hacking position.

According to the present invention, it is possible to immediately detect a physical hacking attempt, it is possible to arrest the hacking by blocking the hacking attempt by sending an alarm sound or by dispatching the police or crime guards.

In addition, since the catch can protrude further forward than in the locked state of the door, the durability of the door lock device is also improved. In addition, even if the door is deformed by physical hacking, the lock is protruded by the amount of deformation of the door, thereby improving security of the door lock device.

2 to 4, the door lock device 100 of the present embodiment is configured to open or close a specific space such as a door of a house, a safe, a door of a vehicle, and the like, and the housing 10 and the catch 20. ), An elastic member 30, a hacking detector 40, a unlocking detector 50, a control unit (not shown), and a drive unit.

The housing 10 is coupled to the interior side of the door 1 and includes a case 11 and a cover 12 coupled to the case. A space is formed between the case 11 and the cover 12 so that various components can be installed. The through hole 111 is formed through the side surface of the case 11.

The catch 20 is for locking and releasing the door 1 and is installed to be linearly movable in the horizontal direction in the housing 10 through the through hole 111 of the case. When the catch 20 is located in the locking position shown in FIG. 2, the catch 20 protrudes with respect to the housing 10 and is inserted into the cap member 70. On the contrary, when the catch 20 moves to the left from the locked position of FIG. 2 and is located at the unlocked position, the catch 20 does not protrude relative to the housing 10 and is not inserted into the cap member 70. Here, the cap member 70 is coupled to the door holder (2), in particular, the interior side of the door holder, is formed so that the insertion hole 71 is inserted into the lock clamp 20 is inserted into the lock clamp. In addition, a stopper 21 is formed at one side of the clamp 20, the stopper 21 is always disposed inside the housing 10 irrespective of the position of the clamp 20. Then, the pressing projection 22 is formed on the other side of the clamp 20. A pair of inclined surfaces 221 inclined in the movement direction of the clamp 20 are formed in the push protrusion 22 symmetrically.

On the other hand, the fastener 20 of the present embodiment is movable in a direction protruding with respect to the housing 10 by a predetermined reference distance in the locking position, unlike the prior art. Here, the reference distance may be set by the designer on the basis of various factors such as the size of the elastic member 30 to be described later, the gap between the door 1 and the door holder (2).

The elastic member 30 is installed inside the housing 10 and is composed of a compression coil spring. One side of the elastic member 30 is supported in contact with the inner surface of the case 11, the other side of the elastic member 30 faces the stopper portion 21 of the stopper and when the door 1 is locked, the stopper portion ( 21). When the door 1 is locked, the elastic member 30 is only in contact with the stopper portion 21 and is not compressed by the stopper portion 21. However, in some cases, the elastic member 30 is compressed by the stopper portion 21 to compress the elastic member ( The length of 30) may be reduced to some extent.

In an abnormal state in which the catch 20 moves further in the direction of protruding relative to the housing 10 from the locking position, since the elastic member 30 is forced to be compressed, the elastic member 30 is clamped at the moment of being compressed. ) Is applied to the stopper portion 21 of the fastener to move the elastic force in the direction immersed with respect to the housing 10. Here, the abnormal state means when the locked door 1 is physically hacked by a hacking tool such as 'Paru'. At the time of physical hacking, the door 1 retreats with respect to the door post 2 so that the gap formed between the door post 2 and the door 1 increases, and thus the housing 10 installed on the interior side of the door 1. Since the retraction is also relatively, the clamp 20 is moved in a direction projecting relative to the housing (10).

The hack detector 40 detects both the locking of the door 1 and the physical hacking of the door 1. The hacking detector 40 is configured as a push switch, but is not limited thereto and may be configured in various forms such as a touch sensor and a photo sensor. Since the push switch 40 is pressed by the push protrusion 22 of the clamp when the door 1 is locked, the push switch 40 outputs an on signal. Then, when the catch 20 is further protruded from the locking position and moved as shown in FIG. 3, the push switch 40 is no longer pressed by the push protrusion 22, and thus outputs an off signal. do. Of course, even when the door 1 is unlocked, the push switch 40 outputs an off signal.

The unlocking detector 50 detects the unlocking of the door 1 and is configured in various forms such as a push switch, a contact switch, and a photo sensor. For example, when the unlocking detector 50 is configured as a push switch, the push switch 50 is pressed by the clamp, for example, the pusher 22 in the present embodiment when the door 1 is unlocked. Is output.

The controller (not shown) receives a signal from the hack detector 40 and the unlocking detector 50 to determine the state of the door 1, for example, the locking, unlocking, and physical hacking of the door 1.

When the on signal is input from the unlocking detector 50, the controller determines that the door 1 is unlocked regardless of the signal input from the hacking detector 40. When the on signal is input from the hack detector 40, the door 10 is locked regardless of the signal input from the unlocking detector 50.

On the other hand, after the on-signal is input from the hack detector 40, the off signal is further input from the hack detector 40, and the unlocking detector for a predetermined time, for example, a time required for the catch 20 to move to the unlocking position. If the on signal from 50 is not input, the controller determines that the door 1 has been physically hacked. If the signal input from the hacking detector 40 is changed from the on-signal to the off-signal and the on-signal is not input from the unlocking detector 50, the direction in which the clamp 20 protrudes from the locking position relative to the housing 1 from the locking position. Because they moved further.

When a physical hack is detected as described above, the control unit operates a warning sound generating device provided in the door lock device 100 so that the alarm sounds loudly, or a police officer or the like is immediately dispatched by informing the police station or a private security company of a physical hacking attempt. It can be done.

The drive unit drives the clamp 20. The driving unit includes a motor (not shown) installed inside the housing 10 and a pressing member 61 for pressing the clamp so that the clamp is moved linearly by receiving the rotational force of the motor. The pressing member 61 is rotatably coupled to the housing. The housing 10 is provided with a button (not shown) for driving the motor or a knob (not shown) for manually rotating the pressing member, so that the user presses the button or presses the knob on the indoor side of the door 1. By rotating, the clamp can be driven automatically or manually. In addition, the authentication unit 62 for authenticating the user is provided on the outdoor side of the door 1, so that the user operates the motor by authenticating the user using the authentication unit on the outdoor side of the door 1 to operate the clamp 20. It can be driven automatically. Here, the authentication unit may be configured in various forms such as a keypad including a button printed with a number from 0 to 9 or a biometric information recognition unit capable of scanning a user's biometric information, for example, a fingerprint or an iris.

Hereinafter, the process of physically hacking the door lock device 100 of the present embodiment using a hacking tool such as 'Paru' will be described in the process of detecting the physical hack by the door lock device 100.

The hacker first inserts the par 3 between the door 1 and the door post 2, as shown in Fig. 4A, and then flips the par 3 in the direction of the arrow. When the par 3 is retracted in this way, the door 1 is pushed by the par 3 to be relatively more pressurized than the scaffold 2 so that the door 1 moves away from the scaffold 2 so that the door 1 Since the gap between the) and the door holder 2 is opened, as shown in (b) of FIG. 4, the housing 10 fixed to the door 1 also moves together. At this time, the door 1 is rotated to a certain degree as shown in (b) of FIG. As such, when the housing 10 moves together with the door 1, the housing 10 also moves in the same direction as the door 1. As such, when the housing 10 moves, the surface of the clamp 20 comes into contact with the peripheral edge of the insertion hole 71 of the cap member such that friction force is generated between the clamp 20 and the cap member 70 or the clamp 20 Is caught in the corner of the insertion hole 71 of the cap member. This friction and / or locking of the clamp 20 serves to fix the position of the clamp 20 even if the housing 10 moves with the door 1. As such, when the clamp 20 is fixed in position, the clamp 20 installed in the housing 10 moves relatively in a direction protruding with respect to the housing 10, and thus, as shown in FIG. 3. Protruding with respect to 10, the elastic member 30 is compressed. As such, when the elastic member 30 is compressed, the push protrusion 22 can no longer press the hack detector 40, that is, the push switch, so that the push switch 40 outputs an off signal instead of the on signal. On the other hand, in this state, since the locking release detector 50 is not pressed, it outputs an off signal.

As described above, when the hack detector 40 outputs an off signal instead of the on signal and the unlocking detector 50 continuously outputs the off signal, the controller determines that the door lock device 100 is physically hacked. If physical hacking is determined, a warning sound or a police officer or the like may be dispatched to cause the hacker to run away or arrest the hacker.

In particular, even if the stopper 20 moves slightly to the right from the position shown in FIG. 2, if the contact between the push protrusion 22 and the hack detector (push switch) 40 is released, the hacking attempt of the hacker is detected very quickly. can do. This is because the hacking detector (push switch) immediately outputs the off signal at the moment when the hacker inserts the par 3 and flips it.

For reference, the physical hacking is not completed by flipping the parlour 3 once, but is completed by repeating the parlour flipping process several times while opening a gap between the door 1 and the door holder 2.

In addition, when the pawl is flipped only once or the number of times that the physical hack cannot be reached, the catch may protrude more than the conventional door lock device. At this time, it returns to its original position, thereby preventing the internal structure of the clamp and the like from being damaged. In other words, if the physical hack is not completed, it is possible to prevent damage to the internal structure such as the clamp, so that not only the durability of the door lock device but also the security against physical hacking are improved.

In general, when physically hacking by 'Paru', the process of flipping the door should be repeated repeatedly, but in the conventional digital door lock device, even if the door is only flipped once, the clamp and the like are damaged.

As described above, the door lock device 100 of the present embodiment is configured to move in a direction protruding with respect to the housing 10, unlike the prior art when the physical hacking attempts, physical, of the door lock device 100 By detecting hacking attempts, there is an advantage in that it is possible to respond in various ways, such as the generation of warning sounds or the dispatch of police.

In particular, if the position of the push projection 22 and the hacking detector 40 is properly set, physical hacking can be detected at the moment, so in some cases, there is no problem in reusing the door lock device that has been attempted. It may not be. This is because, if the hacker stops moving and stops and runs away, the gap between the door and the door holder does not substantially open and the door lock device may not be damaged.

On the other hand, in the present embodiment, the clamp is configured to move horizontally, as shown in Figures 5 and 6 may be configured to move the clamp in a vertical direction.

5 and 6, in the door lock device 100a of the present embodiment, the cap member 70a is respectively fixed from the fixing portion 701 and the fixing portion 701 fixed to the interior side of the door holder 2, respectively. It has a pair of protrusions 702 which protrude and have insertion holes 703 respectively formed therethrough. The center axis of each insertion hole 703 is parallel to the up and down direction, and the pair of insertion holes 703 are arranged coaxially with each other.

The housing 10a includes a case 11a and a cover 12a which are coupled to the interior side of the door 1 and coupled to each other. The housing 10a is installed to protrude from the side surface of the door 1. The housing 10a has a rectangular box shape as a whole. In the housing 10a, a pair of

recesses

101 and 102 which are concave with respect to the side of the housing 10a are formed independently of each other. The pair of

recesses

101 and 102 are spaced apart from each other in the vertical direction. In the pair of

recesses

101 and 102, a pair of protrusions 702 formed in the cap member 70a are disposed, with the door 1 closed. In the housing 10a, a guide portion 111 for guiding the linear movement of the clamp 20 is formed.

The catch 20a includes a pair of inserts 201. The pair of insertion portions 201 are portions to be inserted into and separated from the insertion holes 703 of the cap member, respectively, and the pair of insertion portions 201 is inserted into and removed from the pair of insertion holes 703. (1) is locked and unlocked. In addition, the pair of insertion portions 201 are formed in one body and configured to move in the same direction. However, the clasp may be configured to move in a direction approaching or away from each other by being composed of two parts each having an insertion portion as disclosed in the Patent No. 813,612.

The stopper part 21a is formed in the insertion part 201, and always comes into contact with the elastic member through the intermediate member 80. The elastic member 30 is compressed to a certain degree to always press the intermediate member 80 toward the stopper portion 21a. One side of the elastic member 30 is in contact with the support portion 112 protruding on the inner surface of the case 11, the other side of the elastic member 30 is in contact with the intermediate member (80). The intermediate member 80 is always in contact with the protrusion 202 formed in the clamp 20a.

As illustrated in FIG. 6, in the locked state of the door, the hack detector 40 is pressed by the first push protrusion 22a, and the hack detector 40 outputs an on signal. Then, when the lock 20a is raised so that the door is unlocked, the hack detector 40 is not pressed by the first pusher 22a and thus outputs an off signal, and the lock release detector 50 is provided with the second pushbutton ( 23) Press to output the on signal. In addition, when a physical hacking attempt is made, since the catch 20a moves in a direction protruding with respect to the door, the hack detector 40 outputs an off signal without being pressed by the first push protrusion 22a. .

As described above, in the door lock device 100a configured to move the catch 20a in the vertical direction, that is, in the hook-type door lock device, the catch 20a is released at the time of physical hacking using a hacking tool such as 'Paru'. Since it is configured to move to a certain degree in the direction of protruding with respect to the side of the physical hacking can be detected immediately.

Meanwhile, in FIG. 6, the driving unit for driving the clamp 20a is omitted for simplicity of the drawing. Such a drive unit may be configured to press the clamp 20a as the driving member rotates to move the clamp 20a vertically as shown in FIG. 2. In addition, the driving unit has been commercially applied to the door lock device of the mechanical key type, and has been disclosed in patent applications such as Patent Application No. 2007-10983.

Meanwhile, in the first embodiment, the clamp is configured to be driven automatically according to the operation of the motor, but instead of the motor, the clamp may be configured to be driven by the linear driving force of the solenoid.

In addition, in the first embodiment, the hacking detector is configured to detect both locking and physical hacking of the door, but the hacking detector may be configured to detect only physical hacking of the door lock device. For example, when the hacking detector outputs an off signal when the door is locked, and an attempt is made to physically hack and the catch is moved in a direction protruding from the housing, the hack detector is pressed by the catch to output an on signal. Can be.

Further, in the first embodiment, the door lock device is configured as a door lock device in the form of an auxiliary key without a handle, but may be configured as a main key door lock device in which the handle is included.

In addition, in the first embodiment, the clamp is configured to linearly move in the horizontal direction or the vertical direction, but the movement path of the clamp is not limited thereto, and may be variously changed. For example, the clamp may move simultaneously in the horizontal and vertical directions, may be configured to be rotatable, or may be configured to allow both linear movement and rotation together.

FIG. 8 is a schematic configuration diagram of a door lock device according to a third embodiment of the present invention, and FIG. 9 is a schematic view showing a state in which the clamp shown in FIG. 8 protrudes to a hacking position at the time of physical hacking. 10 is a view for explaining a process of physically hacking the door lock device using a par and the advantages of the door lock device shown in FIG.

8 to 10, the door lock device 100b according to the present embodiment may be applied to a mechanical door lock device or a digital door lock device driven by a power source such as a motor or a solenoid.

The door lock device 100b of the present embodiment includes a housing 10, a clamp 20b, a first elastic member 30, a locking member 90, a second elastic member 35, and a drive unit. do.

The catch 20b is for locking and releasing the door 1 and is installed to be linearly movable in the horizontal direction in the housing 10 through the through hole 111 of the case. When the catch 20b is located in the locking position shown in Fig. 8, the catch 20b protrudes with respect to the housing 10 and is inserted into the cap member 70. On the contrary, when the catch 20b moves downward from the lock position of FIG. 8 to be in the unlocked position, the catch 20b does not protrude relative to the housing 10 and is not inserted into the cap member 70. Here, the cap member 70 is coupled to the door holder (2), in particular, the interior side of the door holder, is formed so that the insertion hole 71 is inserted into the locking clamp 20b is inserted therein. In addition, a stopper portion 21 is formed at one side of the catch 20b, and the stopper 21 is always disposed inside the housing 10 regardless of the position of the catch 20b.

Moreover, the pressing part 24 is formed in the clamp 20b. The pressing part 24 is formed to protrude downward with respect to the bottom surface of the clamp 20b. The pressing portion 24 is formed with an inclined surface 241 inclined with respect to the linear movement direction of the clamp 20b and a contact surface 242 having a normal vector in the same direction as the linear movement direction of the clamp 20b. The inclined surface 241 and the contact surface 242 face in opposite directions to each other, and the inclined surface 241 is disposed to face the side surface of the housing 10.

On the other hand, the clamp 20b of the present embodiment can move more linearly in a direction projecting relative to the housing 10 in the locking position, unlike the prior art.

The first elastic member 30 is installed in the housing 10 and is composed of a compression coil spring. One side of the first elastic member 30 is supported in contact with the inner surface of the case 11, the other side of the first elastic member 30 faces the stopper portion 21 of the clamp and when the door 1 is locked Is in contact with the stopper portion 21. When the door 1 is locked, the first elastic member 30 is only in contact with the stopper portion 21 and is not compressed by the stopper portion 21. However, in some cases, the first elastic member 30 is compressed by the stopper portion 21. 1, the length of the elastic member 30 may be reduced to some extent.

In an abnormal state in which the catch 20b moves further from the locking position in the protruding direction with respect to the housing 10, since the first elastic member 30 must be compressed, the first elastic member 30 is compressed at the moment. From then, an elastic force for moving the catch 30 in the direction immersed with respect to the housing 10 is applied to the stopper portion 21 of the catch. Here, the abnormal state means when the locked door 1 is physically hacked by a hacking tool such as 'Paru'. In this way, if the catch further protrudes from the locked position, the catch is placed in the hacking position. At the time of physical hacking, the door 1 initially retracts with respect to the door post 2 so that the gap 4 formed between the door post 2 increases, and thus the housing installed on the interior side of the door 1. Since 10 is also retracted, the clamp 20b relatively moves in a direction projecting relative to the housing 10.

The locking member 90 is rotatably installed in the housing 10. The locking member 90 includes a main body 91 having a bar shape and a pressurized part 92 protruding from an end of the main body. The main body portion 91 is coupled to the pivot pin 93 which is the central axis of rotation of the locking member 90, the pivot pin 93 is coupled to the case 11 and the cover 12. The press part 92 is a part pressurized by the press part 24. The to-be-pressed portion 92 is provided with a contact surface 921 having a normal vector opposite to the normal vector of the contact surface 242 of the pressing portion. In addition, the to-be-pressed part 92 is provided with a to-be-pressed surface 922 having a normal vector in a direction opposite to a normal vector of the contact surface at a portion facing the contact surface 921 in the opposite direction.

The locking member 90 is rotatable between the unlocking position and the locking position. The locking member 90 is always disposed at the unlocking position shown in FIG. 8 when the door lock device is normally operated. When the locking member 90 is disposed in the unlocking position as described above, when the locking clamp 20b moves linearly between the locking position and the unlocking position, the linear movement of the locking clamp 20b can be freely made without being disturbed. Then, the pressing portion 24 of the clamp keeps in contact with the body portion 91 of the locking member at all times.

On the other hand, when the clamp 20b moves linearly in a direction further protruding from the locking position shown in Fig. 8, the inclined surface 241 of the pressing part 24 of the clamp 20b is pressed by the clamping member 90. Since the pressing surface 922 of 92 is pressed, the locking member 90 is rotated counterclockwise about the pivot pin 93 so as to be far from the clamp. In this way, if the clamp 20b protrudes so that the entire pressing portion 92 of the locking member is disposed under the pressing portion 24 of the clamp, the locking member 90 will be described later as shown in FIG. It rotates in the clockwise direction by the elastic force of the second elastic member 35 is disposed in the locking position. When the locking member 90 is disposed in the locking position as described above, even if the clamp 20b is retracted in the direction in which the clamp 20b is immersed in the housing 10 at the position shown in FIG. 9, the contact surface of the pressing part 24 of the clamp 20b ( 242 and the contact surface 921 of the pressing portion 92 of the locking member 90 are in contact with each other, and further, the pressing portion 92 of the locking member 90 is caught by the catch 20b, so that the locking member 90 ) Is prevented from rotating in the clockwise direction, thereby preventing the retraction of the stopper 20b. That is, the clamp 20b is protruded more than the state shown in Fig. 8, as shown in Fig. 9, and this protruding state continues to be maintained.

The second elastic member 35 elastically biases the locking member in a direction approaching the clamp. In this embodiment, the second elastic member 35 is composed of a compression coil spring, one end of the compression coil spring is in contact with the main body 91 of the locking member, the other end of the compression coil spring to the case 11 The contact support 112 is projected.

The drive unit drives the clamp 20b. The driving unit includes a motor (not shown) installed inside the housing 10 and a pressing member 61 for pressing the clamp so that the clamp is moved linearly by receiving the rotational force of the motor. The pressing member 61 is rotatably coupled to the housing. The housing 10 is provided with a button (not shown) for driving the motor or a knob (not shown) for manually rotating the pressing member, so that the user presses the button or presses the knob on the indoor side of the door 1. By rotating, the clamp can be driven automatically or manually. In addition, the authentication unit 62 for authenticating the user is provided on the outdoor side of the door 1, so that the user operates the motor by authenticating the user using the authentication unit on the outdoor side of the door 1 to operate the clamp 20b. It can be driven automatically. Here, the authentication unit may be configured in various forms such as a keypad including a button printed with a number from 0 to 9 or a biometric information recognition unit capable of scanning a user's biometric information, for example, a fingerprint or an iris.

Hereinafter, the reason why the security of the door lock device 100b is improved after explaining the process of physically hacking the door lock device 100b using the hacking tool such as 'Paru' will be described with reference to FIG. 5. do.

The hacker first inserts the par 3 between the door 1 and the door post 2, as shown in Fig. 10A, and then flips the par 4 in the direction of the arrow. When the par 3 is retracted in this manner, the door 1 is pushed by the par 3 to be relatively more pressurized than the scaffold 2 so that the gap 4 between the door 1 and the scaffold 2 opens. The door 1 is crushed. When the door is deformed in this manner, the housing of the door lock device fixed to the door is also retracted with respect to the door holder by the amount of deformation of the door. At this time, the door 1 is rotated to a certain degree as shown in (a) of FIG. When the door 1 is deformed in this manner, the housing 10 of the door lock device fixed to the door is also retracted with respect to the door holder 2 by the amount of deformation of the door 1.

When the housing 10 is moved in this way, the surface of the clamp 20b is in contact with the peripheral edge of the insertion hole 71 of the cap member to generate a friction force between the clamp 20b and the cap member 70 or the clamp 20b Is caught in the corner of the insertion hole 71 of the cap member. In particular, although not shown in the present embodiment, as disclosed in Korean Utility Model Application No. 20-2009-17060 and Korean Patent Application No. 10-2010-74883, the interior or exterior surface of the clasp 20b is not shown. If projections or grooves are formed, the projections or grooves can be more effectively caught on the edge of the insertion hole of the cap member. This frictional force and / or locking of the clamp 20b serves to fix the position of the clamp 20b even if the housing 10 moves with the door 1. When the clamp 20b is fixed in position as described above, the clamp 20b installed in the housing 10 moves relatively in a direction protruding with respect to the housing 10, whereby the first elastic member 30 is compressed. While the clasp 20b moves further in the direction in which it protrudes with respect to the housing 10. In this process, the inclined surface 241 of the pressing portion 24 of the clamping portion 20b presses the pressurized surface 922 of the pressurized portion 92 of the locking member 90, and thus is shown in FIG. 9. As it is, the locking member 90 is disposed in the locking position and the clamp 20b is to maintain a more protruding state than the state shown in FIG. That is, the catch 20b protrudes more than before the physical hacking attempt. When the protruding length of the catch 20b is increased in this way, even if a physical hacking attempt is made, the catch 20b can be effectively prevented from being separated from the insertion hole 71 of the cap member, and thus the door lock device 100b. Security is greatly improved. If the protruding length of the clamp 20b remains the same both before and after physical hacking as in the conventional door lock device, as the door 1 is deformed, the clamp 20b is inserted from the insertion hole 71 of the cap member 70. As a result, the locked state of the door 1 cannot be maintained.

Meanwhile, although the locking member is rotatably installed in the third embodiment, the locking member may be installed to be linearly movable with respect to the housing as illustrated in FIGS. 11 and 12.

11 and 12, in the door lock device 100c of this embodiment, the curved portion 241c is formed in the pressing portion 24c of the clamp 20c. As shown in FIG. 6, the curved portion 241c is formed to protrude toward the pressing portion of the locking member. In addition, the pressing surface 922c of the locking member 90c is formed in a plane inclined with respect to the linear movement direction of the clamp 20c. Therefore, the curved surface portion 241c of the pressing portion 24c of the clamp 20c operates to press the pressurized surface 922c of the locking member 90c when the clamp 20c is linearly moved.

The locking member 90c can be linearly moved in a direction intersecting with the linear movement direction of the clamp 20c, that is, orthogonal to each other. The locking member 90c is restrained by the movement so that linear movement is possible. For example, although not shown, the linear movement is constrained by the guide protruding from the case. The locking member 90c is linearly movable between the unlocking position shown in FIG. 11 and the locking position shown in FIG. 12. When a physical hacking attempt is made and the catch 20c is moved to protrude more than the state shown in FIG. 11, the catching member 90c moves linearly away from the bottom of the catch 20c, eventually FIG. 12. It is arranged in the locking position shown in. In the locking position, even if the catch 20c is retracted, the catching member 90c is caught by the bottom face of the catch 20c, and the contact surface 242 of the pressing portion 24c of the catch 20c is catching member 90c. Since no driving force is generated in contact with the contact surface 921 of the member and the locking member 90c is linearly moved, the locking member 90c continues to move in that state. Thus, the protruding length of the clamp 20c is maintained in the state shown in FIG.

Meanwhile, in the third embodiment, the inclined surface is formed on the pressing portion, but the curved portion may be formed on the pressing portion. Here, the curved portion may be formed concave with respect to the inclined surface as shown in FIG. 11 or convexly with respect to the inclined surface. In addition, although the curved portion may be formed to have a single curvature, the curvature may be changed, and in some cases, concave and convex may be alternately formed. In addition, both the inclined surface and the curved portion may be formed in the pressing portion. The inclined portion or the curved portion may be formed in both the pressing portion and the pressurized portion.

In addition, in the third embodiment, the second elastic member is configured to be provided, but if the locking member is disposed above the clamp so that the gravity of the locking member acts in the direction in which the locking member approaches the clamp, the second elastic member Is not necessarily provided.

In addition, in the third embodiment, the inclined surface is formed on the pressing portion of the clamp, or the curved surface is formed on the pressurized surface of the locking member, but the inclined surface or the curved surface may not be formed, and in this case, the pressing portion of the clamp In the linear movement process, the driving force for driving the locking member by pressing the pressurized part of the locking member, for example, a rotation driving force or a linear driving force is generated. However, the inclined surface or curved surface serves to generate the driving force more efficiently.

On the other hand, in the third embodiment, when the locking member is disposed at the locking position, the locking member cannot be moved to the unlocking position without disassembling the door lock device. However, as shown in FIG. 13, the release member is further formed on the locking member. By constructing the door lock device, the locking member can be moved to the unlocked position without disassembling the door lock device.

Referring to FIG. 13, in the door lock device 100d of the present embodiment, the release portion 94 of the locking member 90d is a part of the main body 91, that is, the pressurized portion 92 from the pivot pin 93. Refers to a portion extending in the opposite direction of. In the state shown in FIG. 13, when the release part 94 is pressed using the release means, the locking member 90d is rotated in a direction in which pressurization with the catch 20b is released. 1 The elastic force of the elastic member 30 is moved to the locking position shown in FIG. Here, the latch release means is composed of a release portion 94 and a drive mechanism. The driving mechanism (not shown) may be configured in various forms such as a structure of links or links and a gearbox for pressing the release unit 94 by receiving a driving force of the motor or the solenoid and the motor or the solenoid. When the driving mechanism is configured as described above, it is possible to automatically release the locking member by operating the motor or the solenoid. In addition, the driving mechanism is made of a link or gear, etc., a portion of the link may be exposed to the interior side of the door, so that the user can be configured to press the exposed portion.

On the other hand, the door lock device of the previous embodiment may be applied in various forms, such as a lock of the safe, a lock of the car door or a lock for controlling access to a specific space.

In addition, in the third embodiment, the clasp is configured to be linearly movable, but the clasp may be configured to rotate, and the clasp may be configured to linearly move in a vertical direction instead of a horizontal direction.

In addition, although the first elastic member is provided in the third embodiment, the first elastic member may not be provided.

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.
