The door lock device is provided with a locking device so that the door can not be opened outdoors. The most common type is a mechanical door lock which locks and unlocks the door lock manually using a key.

However, such a mechanical door lock has a problem of poor security because of its simple structure. In order to solve such a problem, recently, a solenoid type door lock which drives a dead bolt by using an electromagnet and a clutch, a dead bolt by a motor and a motor is driven by a user authentication process such as a password or fingerprint recognition or card recognition A motor-driven door lock is mainly used. Of these, the motor-driven type, which is simple in structure and relatively low in power consumption, is more preferred in recent years.

The motor-driven door lock is generally referred to as a digital door lock. In the case of the digital door lock, the keypad device is fixedly installed on the outdoor side of the door, and the Mortis device is fixedly installed on the door side of the door. Wherein the moti ts device comprises a power supply part, a driving motor, a dead bolt and a ratchet bolt, and is interlocked with the keypad device, The door lock is locked or unlocked in conjunction with the opening / closing handle or the push-pull operation bar.

[0003] Such a digital door lock is a conventional technology, and a clutch structure of an electronic door lock is provided to prevent a malfunction of a digital door lock as disclosed in the registration utility model No. 20-0464252. There has been found a locking device for a front door such as that of Registration No. 10-0310006, and a latch-pivoting door lock motis used for a push-pull door lock as in the case of the public utility model No. 20-2015-0001163 has been found.

However, in the case of a conventional digital door lock, a rotary knob or a push-pull type operation bar is used for unlocking the door lock, or a dead bolt in the protruded mothis device is inserted into the device by operating the keypad device, When the dead bolt is operated in a state in which it is interfered with the bracket of the door frame, a load is often generated in the driving motor due to interference resistance between the door bolt and the door bolt. Therefore, the lifetime of the driving motor is shortened, Is shortened.

That is, in the conventional door lock, the dead bolt and the ratchet bolt are concurrently inserted and unlocked in the unlocked state. In this unlocking process, the automatic door opening / closing device or the room, The dead bolt interferes with the latch in the door frame, so that the dead bolt can not be smoothly and quickly inserted into the inside of the Mortise unit due to mutual interference resistance, and the drive motor is damaged or unlocked .

The conventional digital door lock includes a first drive shaft portion to which an accessory rotated by a rotary knob or an operation bar is coupled to a second drive shaft portion to which an accessory to be rotated by the drive motor is coupled, And the third drive shaft portion to which the first drive shaft is coupled. Therefore, the structure is very complicated and is made up of a very large number of accessories, so that the manufacture is very troublesome and the production cost is very expensive. Therefore, the economical burden of the consumer is great and the seller is not profitable. I have.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems described above, and it is an object of the present invention to provide a motor-driven dead bolt and a rotatable ratchet bolt, And a drive motor is connected to the operating rotation port so that the deadbolt is rotated through the rotation operation of the indoor rotation port or the outdoor rotation port, And the ratchet bolt are operatively linked to each other,

The digital door lock according to the present invention is characterized in that a dead bolt 10 and a ratchet bolt 20 built in a body of a motis body 100 are detached from a side of the body 100 and fixed to the door frame The deadbolt 10 is forwardly projected and depressed and retracted through the operation of the driving motor 30 in the main body 100. The ratchet bolt 20 The door is closed or opened while rotating and sliding while interfering with a latch (a metal body for inserting the dead bolt and the ratchet bolt in the door frame into the metal body (not shown in the figure)) by an artificial force of the user will be.

In the body 100 of the present invention, the deadbolts 10 and the ratchet bolts 20 are inserted in parallel and the drive motor 30 is disposed on one side of the body 100. The drive motor 30 The drive gear 31 is exposed.

A separate cover 100 is coupled to the main body 100 to seal the inside of the main body 100.

Particularly, inside the main body 100, an indoor rotary shaft 40, an operation rotary shaft 50, an intermittent lever 60, and an outdoor rotary shaft (not shown) And a through hole (not shown in the figure) is formed in the main body 100 and the cover 110. These through holes are respectively provided with an indoor side rotation hole 40 and an outdoor side Since the central portion of the side rotary shaft 70 is exposed, the rotary handle knob or the push bar type operation bar can be connected through the through hole.

Accordingly, when the handle knob is rotated or the operating bar is operated in the form of a push-pull, a rotational force from the rotational knob rotates the indoor side rotary shaft 40 or the outdoor side rotary shaft 70, Can be achieved.

The indoor side rotator 40 is located on the inner bottom surface of the main body 100 and includes a return spring 121 having one end connected to the main body 100, 40 is rotated in one direction by an artificial force, it is automatically rotated to its original position by the restoring force of the return spring 121. [

In the center of the indoor side rotatable member 40, grooves 41 for connecting the electric handle knob or the actuating bar are formed to pass therethrough. On the upper surface of the indoor rotary member 40, a first step 42 and a second step 43 protruding from the upper surface of the first step 42.

The operating rotary member 50 is rotated in a state of being closely attached to the upper surface of the indoor rotary member 40. The operating rotary member 50 has a downward protruding / The protruding and retracted operating rod 52 is protruded so that the protruding and retreating latching part 51 is coupled to the dead bolt 10. An electromotive driving motor 30 A rotary gear 53 engaging with the driving gear 31 of the rotary shaft 50 is protruded and an operation interfering portion 54 having a fan shape is formed between the rotary shaft 50 and the rotary shaft 53 It is.

At this time, the operation interfering portion 54 is formed within the rotation range of the first step 42 of the indoor side rotary tool 40. When the indoor side rotary tool 40 rotates, the first step 42 And the one side of the operation interfering portion 54 are engaged with each other so that they rotate at the same time.

The operating rotary member 50 may be rotated together with the rotation of the indoor rotary member 40. While the rotational force of the driving motor 30 is transmitted through the driving gear 31 and the rotary member 53, And can be independently rotated independently of the indoor side rotatable tool 40. As shown in Fig.

Therefore, the dead bolt 10 to which the protruding / retracting latching part 51 is coupled can repeat the forward projecting and retracting operation with respect to the main body 100 due to the rotation action of the operating rotary tool 50.

The intermittent lever 60 located at the upper portion of the operating rotary member 50 is formed with an insertion hole 61 at the center thereof and the distal end of the operating rotary member 50 is inserted into the insertion hole 61 And has a coupling structure capable of rotating the intermittent lever 60 with respect to the operating rotary tool 50.

The intermittent lever 60 is formed with a rotation interfering portion 62 having a stepped shape on one side thereof and the rotation interfering portion 62 is provided at a position corresponding to the second step 43 And a support arm 64 protruding from the other end of the intermittent lever 60 with a stopping protrusion 63 protruding from the stopping lever 60 is formed integrally with the stopping lever 60, 63 serve to restrain the ratchet bolt 20 from being rotated.

That is, a ratchet accommodating portion 101 is formed at one side of the main body 100 so that the ratchet bolt 20 can be rotated and flow in the ratchet accommodating portion 101, The ratchet bolt 20 is always protruded to one side of the main body 100 because the elastic spring 120 is formed at one side of the ratchet receiving portion 101 and is resiliently disposed between the inner wall of the ratchet receiving portion 101.

In addition, the ratchet bolt 20 has a parallelogram shape formed by a straight line and a slope on both sides in a plan view, a protruding step (not shown in the figure) is formed on the upper and lower sides, And the protruding jaws are held in engagement with the locking jaws 63 of the intermittent lever 60.

Therefore, when the latching jaw 63 of the intermittent lever 60 is engaged with one side of the protruding jaw, the ratchet bolt 20 can only flow in the lateral direction, and the rotation of the intermittent lever 60 Accordingly, when the latching jaw 63 is separated from the protruding jaws, the ratchet bolt 20 is rotated and rotated in the lateral direction.

Particularly, the switching clutch 80, which is separately provided, is coupled to the intermittent lever 60 so that the switching clutch 80 is axially coupled to the intermittent lever 60 to be freely rotatable, A hook 83 is protruded at one side of the clutch 80 so that the hook 83 is connected to the dead bolt 10 in a slit shape so that the switching clutch 80 are rotated.

The engagement grooves 81 and the free grooves 82 are formed in the upper surface of the switching clutch 80 so that the free grooves 82 are perpendicular to each other. It has a long length.

The outdoor rotary shaft 70 is closely attached to the lower portion of the inner surface of the cover 110 and is coupled to the upper portion of the intermittent lever 60. At the center of the outer rotary shaft 70, grooves 71 And a support portion 73 protruding downward through the fitting hole 72 is formed at one end of the first step portion 43. The second step 43 of the electric room side rotary member 40 is formed at the bottom surface, And an engaging groove portion 74 for allowing the tip portion to flow in a state of being inserted is formed.

When the outdoor side rotary member 70 rotates, the fitting hole 72 is guided into the engaging groove 81 or the free groove 82 of the switching clutch 80 and the long groove 82 The intermittent lever 60 can not be rotated upwards but inserted into the engagement groove 81 having a short length, the intermittent lever 60 is rotated upward due to interference between the intermittent lever 60 and the intermittent lever 60.

An upper portion of the second step 43 of the inner chamber side rotary shaft 40 is inserted into the locking groove portion 74 of the outdoor side rotary shaft 70 so that the locking groove portion 74 has a predetermined angle Side rotatable member 40. When the indoor rotary member 40 is rotated or the outdoor rotary member 70 is rotated, the rotation of the outdoor rotary member 70 causes interference or trouble But instead serves to limit the angle of rotation between the two.

Hereinafter, the process of opening and closing the door lock and the opening and closing of the door lock in the indoor or outdoor direction will be described in detail with respect to the digital door lock of the present invention having such a structure.

First, when the indoor side rotary tool 40 in the main body 100 is rotated using a handle knob or an operation bar for opening the door to move outward from the indoor side, a dead bolt (not shown) 10 and the ratchet bolt 20 are all protruded, the indoor side rotator 40 starts to rotate.

At this time, the intermittent lever 60 has a force to be downwardly rotated by the compression spring 122, so that the latching jaw 63 of the intermittent lever 60 prevents the ratchet bolt 20 from rotating, The door itself can not be opened or closed due to the interference between the door frame and the latch in the door frame.

When the indoor side rotary shaft 40 starts to rotate, one side of the first step 42 of the indoor side rotary shaft 40 interferes with one side of the operation interfering portion 54 of the rotary shaft 50 Thereby rotating the operating rotary member 50 together.

When the operation rotary member 50 starts to rotate at the same time as the rotation of the indoor rotary member 40, the deadbolts in the engaged state with the rotation of the operation member 52 of the rotary member 50 10 are moved in a depressed and retreated state as shown in FIG. 8 (a), and the state of being out of the door frame is made.

When the dead bolt 10 is completely retracted, the second step 43 of the indoor side rotary member 40 is rotated in the direction of the rotation of the intermittent lever 60 The stopper lever 60 is brought into contact with one side of the rotation interfering portion 62 and starts to rotate the intermittent lever 60 in the same state as in Figs. 8 (b) and 8 (c).

Next, the deadbolt 10 is retracted while the operating rotary tool 50 is interrupted and rotated primarily in accordance with the continuous rotation of the indoor side rotary tool 40, and the intermittent lever 60 9 (a) to 9 (c), the stopping lever 60, which was in a state of being interfered with the ratchet bolt 20 together with the complete retraction of the dead bolt 10 (no interference with the door frame) The ratchet bolt 20 is rotated in the lateral direction and rotatable.

Therefore, in such a state, when the user pushes the door by force, the door lock is in the unlocked state, so that interference by the dead bolt 10 does not occur. Since the ratchet bolt 20 is rotatable, The door is naturally rotated and depressed while the interference occurs, thereby opening the door.

The operating structure of the ratchet bolt 20 when the door is opened due to an artificial force of a passenger in a state where the dead bolt 10 is recessed and retreated is shown in FIG.

10 (a), the horizontal surface of the ratchet bolt 20 is interfering with the inner surface of the door frame in the opening direction of the door, and the engagement step 63 of the intermittent lever 60 is engaged with the inner surface of the ratchet bolt 20 The door can not be opened in a state in which it is locked on one side.

In this state, the operating rotary tool 50 is rotated by the rotation of the indoor side rotary tool 40 to retract the dead bolt 10 and sequentially rotate the intermittent lever 60 upward, and the ratchet bolt 20 And the intermittent lever 60 are lost, the door will be opened by an artificial force of the user, and the ratchet bolt 20 rotates as shown in FIG. 10 (b) due to such pressing force will be.

When the rotation of the ratchet bolt 20 occurs, the electric horizontal plane will be inclined by rotation as shown in (c) of FIG. 10, and will move laterally inward due to interference with the door frame, The door can be opened naturally due to the depressing movement of the ratchet bolt 20.

The reason why the ratchet bolt 20 is rotated in the state where the dead bolt 10 is retracted is to minimize the interference force with the door frame acting on the dead bolt 10, The load acting on the drive motor 30 for causing the ratchet bolt 20 to take charge of the dead bolt 10 can be minimized. The description of the load of the drive motor 30 will be referred to later.

When the door is opened and the person is out of the door or the door is to be closed again, the ratchet bolt 20 is rotated as shown in FIG. 11, so that the force of the artificial force or the door closing force When the door rotates in the closing direction again, the lower horizontal surface of the ratchet bolt 20 and the door frame interfere with each other and rotate about the ratchet bolt 20 as shown in FIG. 11 (a).

11 (b), the horizontal surface may be inclined to the inside of the ratchet receiving portion 101 due to an interference force with the door frame, The ratchet bolt 20, which is recessed inward, is protruded again due to the reaction force of the elastic spring 120 and inserted into the door frame as shown in FIG. 11 (c), so that the closed state of the door can be maintained.

Then, when the metal sensing means or the like provided inside the main body 100 senses the latches or the like in the door frame and the drive gear 31 is automatically operated, the dead bolt 10 which has been retracted in the recessed state advances and protrudes The lock state of the door lock can be maintained and the door lock state can be maintained.

Particularly, since the dead bolt 10 will protrude after the door is closed by the ratchet bolt 20, no interference or resistance occurs between the dead bolt 10 and the latch in the door frame, It is possible to prevent an unreasonable load from being applied to the movable member 30 and to prevent malfunction or lock from being caused.

As described above, the unlocking and locking process of the door lock according to the opening and closing of the door in the indoor direction has been examined, and the operation process according to the unlocking of the door lock and opening of the door at the outdoor side will be described.

First, when the outdoor side rotary member 70 is rotated using a handle bar, an operation bar, or the like without the authentication of the keypad device installed on the outdoor side of the door, the dead bolt 10 is rotated, The ratchet bolt 20 should not be retracted.

12, the fitting hole 72 formed in the support portion 73 of the outdoor side rotary valve 70 is engaged with the switching clutch 80 (see Fig. 12) ) Into a free groove 82 formed in a long length, so that a free rotation state without any interference is achieved.

The ratchet bolt 20 is also in the non-rotating state of the intermittent lever 60. The ratchet bolt 20 is in the unrotated state of the intermittent lever 60, The latching jaw 63 of the intermittent lever 60 is latched on one side of the ratchet bolt 20 so that the ratchet bolt 20 can not rotate and the upper horizontal surface of the ratchet bolt 20 is in close contact with the inner surface of the door frame, So that the door lock state can be maintained stably.

On the other hand, when a user authentication process such as a password is performed using a keypad device outside the door, the driving motor 30 is operated to rotate the driving gear 31 to engage with the driving gear 31 as shown in FIG. 13 And the deadbolt 10 is recessed and retracted due to the rotation of the operating rotary member 50 so that the door lock is released.

When the dead bolt 10 is retracted, the rotation of the switching clutch 80 connected to the dead bolt 10 occurs, and the positions of the latching groove 81 and the free groove 82 are also changed 13 (b), the open end of the engagement groove 81 is directed toward the fitting hole 72 of the outdoor side rotary shaft 70.

Therefore, when the outdoor side rotary tool 70 connected to the handle knob or the operation bar is rotated to open the door in the retracted state of the dead bolt 10 as described above, the support portion of the outdoor side rotary tool 70 73 and the insertion port 72 are caused to rotate and the insertion port 72 is guided and inserted into the engagement groove 81 of the switching clutch 80. After a certain amount of rotation, Interference occurs between the end of the locking groove 81 and the fitting hole 72. [

Since the rotation force of the outdoor side rotary tool 70 will act as a force for lifting up the switching clutch 80 and the intermittent lever 60 from the moment when mutual interference occurs, the upward movement of the intermittent lever 60 The engagement jaws 63 of the intermittent lever 60 can be separated from one side of the ratchet bolt 20 by rotation.

Therefore, when the deadbolt 10 is depressed through the authentication of the keypad device and the outdoor knob or the operation bar is operated to open the door so that the outdoor knob 70 is rotated, the interlock lever 60 The ratchet bolt 20 is rotated in the upward direction to make a state in which the ratchet bolt 20 can be rotated. In this state, when the door is pulled to be pulled open, interference between the horizontal surface of the ratchet bolt 20 and the door frame causes the ratchet The bolt 20 can be retracted to the inside of the main body 100 due to the interference between the inclined surface and the door frame due to rotation simultaneously with the primary rotational movement in the ratchet receiving portion 101 It is.

Therefore, due to the rotation action of the ratchet bolt 20 in a state in which the dead bolt 10 is recessed and retreated, the user can easily open the door on the outdoor side, and even if the door is closed, 11, the door lock can be maintained simply and stably. When the door is closed, the door motor automatically detects the latch in the door frame and the deadbolt 10 is operated while the driving motor 30 is operating. And the outdoor side rotary shaft 70 rotated by an artificial force will be reversely rotated to the original position by the return spring 121. When the outdoor side rotary shaft 70 is rotated reversely So that the rotation of the ratchet bolt 20 is restrained when the intermittent lever 60 is rotated downward again.

Particularly, the dead bolt 10 is recessed backward through the operating rotary member 50 by an artificial rotational force of the indoor side rotary member 40 or retracted by the operation of the drive motor 30, The dead bolt 10 can be quickly and smoothly protruded while being elastically moved in the advancing direction by the separately provided tangential spring 123 so as to rapidly maintain the lock state of the door lock .

Therefore, in the digital door lock of the present invention, when the handle knob is rotated to open the door on the indoor side, the ratchet bolt is pivoted after the retraction of the dead bolt, so that the door lock is released and the door is opened safely and quickly. Even if the door is opened after the approval of the keypad device, the ratchet bolt is pivoted after the retraction of the dead bolt, so that the door is opened. Therefore, it is possible to realize excellent efficiency and economical efficiency due to the simplified structure and operation I will direct.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the present invention as defined by the appended claims.
