Description

Door Lock Device

The present invention relates to a door lock device electrically operated with a key operation, and more particularly to a door lock device in which a mechanical mechanism electrically operated in the door lock device is integrated in the door lock case.

In general, a door lock device having a dead bolt and a latch bolt is installed in a lock case. The dead bolt can be operated by inserting a key or operating a combination of electronic and mechanical, and the latch bolt can be operated by a handle.

Electronically locking / unlocking the dead bolt requires a mechanical mechanism associated with the latch bolt.

That is, when the latch bolt is pulled into the case by the handle, the dead bolt must be drawn through the mechanical connection mechanism.

And even if the latch bolts are pulled out of the case again, the dead bolts should be kept in place, and the dead bolts must be locked through the mechanical connection mechanism when the handle is operated again.

However, looking at the door lock device installed in the conventional lock case, the dead bolt and latch bolt does not have a device that can operate in conjunction with each other. Most lock cases have a connection mechanism implemented in the door lock device body.

Therefore, this has the following problem.

First, the mechanical connection device that can link and operate the dead bolt and the latch bolt installed in the case and the lock case is inevitably installed separately from each other. Since it is necessary to consider the various functions of the door lock body and has no limit of design.

Second, it is not possible to change the position of the door lock case only according to whether the opening or closing direction of the door is left or right. This is because the structure of the door lock body must also be changed.

Third, if the dead bolt is impacted somewhere while it is out of the case, the shock is transmitted to the dead bolt as it is, so that the feeling of operation is not good and the parts may be damaged.

Fourth, if the operation handle is forcibly manipulated from the outside, there is a high possibility that each part cannot endure and cause a failure.

The present invention has been made in view of the above circumstances, by incorporating the mechanical mechanism of the door lock device into the door lock case to increase the design design deformation of the door lock body, and to provide a door lock device to achieve a reliable operation The purpose is.

In addition, the present invention is to enable the functional use even if the position of the lock case in response to the opening direction of the door.

In addition, the present invention is to provide a mechanical protection by cushioning the shock even when the dead bolt is impaired when performing the door lock.

In addition, the present invention is to protect the door lock device and to open the door even if the handle is forcibly operated by an external intruder.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1a is a perspective view of the door lock device of the present invention, Figure 1b is a front view of the door lock device coupled to the door lock body.

In Figs. 1A and 1B, reference numeral 10 denotes a case of the door lock device.

The case 10 is composed of a pair of dividers 10A and 10B that are split and assembled to face each other as shown in FIG. 8 and a front plate 10C assembled to the front of the dividers 10A and 10B. .

The front plate 10C of the case 10 has holes 10-1 and 10-2 through which the dead bolt 20 and the latch bolt 25 are respectively recessed. The dead bolt 20 is arranged side by side in the case 10 as in the conventional door lock device, and reciprocating operation by opening and closing the key (1) or the inner opening and closing knob (2) as shown in Figure 1a The latch bolt 25 is opened and closed by a handle 3.

According to the present invention, the door lock can be released by the key 1 in the door lock state (the dead bolt 20 is advanced), but the dead bolt 20 is not released without receiving an electric drive signal. The door cannot be opened by this.

Therefore, in the present invention, the door may be unlocked by operating the dead bolt 20 with the handle 3 even though the key or the electric driving signal is received. Herein, the electric driving signal means a signal generated when the password value set in the memory and the input value input from the outside match.

Therefore, the present invention can encrypt a user's number, fingerprint or iris, etc., and can use any one of driving signals for releasing the door lock when the input value input by the user matches the set value.

In the case 10, as shown in Figs. 2 and 3, the guide shaft 30 guides the linear reciprocating motion of the dead bolt 20 and limits the reciprocating motion of the dead bolt 20 as shown in Figs. ) Is installed.

The guide shaft 30 is inserted into the long hole 21 of the dead bolt 20, the dead bolt 20 has a stroke section (L) for linear reciprocating motion by the length of the long hole (21).

The dead bolt 20 is a linear reciprocating operation by the operation shaft 40 operated by the key, the operation shaft 40 is pivotally rotatable about the center of the case 10 as shown in FIG. The protrusion shaft 44 is assembled to the operation shaft 40 and supported by the spring 45 force.

The operation shaft 40 extends a predetermined amount in the radial direction below the boss portion 41 having the key operation hole 41a penetrated in the center and the outer peripheral surface of the boss portion 41 as shown in FIG. Arms 42 for rotating the bolt 20, teeth 43 formed in a circumferential direction over the outer circumferential surface of the boss 41, and projections on the outer circumferential surface of the boss 41 A bundle bundle guide groove 46 is provided to slidably couple the bundle 44 in the axial direction and simultaneously hold the protrusion bundle 44 with a spring 45 force.

The arm part 42 of the operation shaft 40 is operated within a rotation angle range of approximately 90 degrees via a spring 35 connected to the case 10. When the operation shaft 40 is rotated by a key, the arm 42 is inserted into the recess 22 of the dead bolt 20 to overcome the force of the spring 35 and angularly move, and the dead bolt 20 It has a linear reciprocating motion.

The protrusion bundle 44 is changed to its position in an upright position by the elastic restoring force of the spring 45 in a falling posture when the driving motor 104 included in the protrusion bundle manipulation means described below receives a lock release driving signal. have. In addition, the protrusion bundle 44 maintains the downward stance as long as the unlocking drive signal does not fall on the driving motor 104 while the operation shaft 40 moves the dead bolt 20 forward.

The operation shaft pivot lever 50 is hinged to the operation shaft 40.

The operating shaft pivoting lever 50 has a locking jaw 51 at one end as shown in FIG. 3 and is hinged on the operating shaft 40, and the other end of the operating shaft pivoting lever 50 is an angle conversion port ( 70 is hinged.

Therefore, when the protrusion bundle 44 maintains the ascending position as shown in FIG. 4A, the protrusion bundle 44 is hung on the locking jaw 51 of the operation shaft pivot lever 50 in the clockwise direction. It can be rotated approximately 90 degrees, on the contrary, when the projection bundle 44 maintains the lowered posture, it is not possible to hang the projection bundle 44 by the locking jaw 51 of the operation shaft pivot lever 50, and thus the operation shaft It is not possible to operate the clockwise rotation in the clockwise direction.

12A to 12C, the angle conversion hole 70 hinged to the operating shaft pivoting lever 50 contacts the inner concave surface 67 of the handle lever 60 and guides the case 10. While operating along the turning (13), the operation shaft rotation lever 50 is operated at an operation angle larger than the rotation operation angle of the handle lever 60.

The angle conversion port 70 rotates the handle lever 60 in the present embodiment to 35 degrees to function to rotate the operating shaft rotation lever 50 to about 95 degrees.

The angle conversion port 70 is formed with a guide projection 71 on the upper surface, the guide projection 71 is inserted into the guide hole 13 formed on one side of the case 10. Therefore, when the angle conversion port 70 receives the clockwise operation force of the handle lever 60, the operation operation of the handle lever 60 is switched to the rotation operation of the operating shaft rotation lever 50 while receiving the turning guidance of the guide officer 13. It is supposed to play a role.

When the dead bolt 20 is in the unlocked state, that is, when the dead bolt 20 is retracted, the angle converting hole 70 compresses the spring 132 and again the dead bolt 20 moves forward. The spring 132 is returned to its original position by the elastic restoring force. At this time, the spring 132 is disposed on the spring support 130 so as to be disposed on the rear upper surface of the dead bolt 20, the pressure support 131 is a sliding guide in the guide groove (130a) to the spring support 130 The spring 132 has one end supported by the pressure port 131 and the other end supported by a screw 133 screwed to one side wall of the guide groove 130a.

And a pair of lever blades 62 and 63, which are dividedly coupled to the handle connecting shaft 61, and have projection insertion grooves 62a and 63a into which the engaging projections 61b and 61c are inserted.

At this time, the first locking projection 61b is inserted into both side projection insertion grooves 62a of the lever blades 62 and 63, and the second locking projection 61b is smaller in length than the first locking projection 61b. If it is, only the projection insertion groove 63a formed only on one side of the lever blade 62 is inserted.

When the handle lever 60 is forcibly operated, the first locking protrusion 61b exerts a safety function as it is first broken as shown in FIG. 14A, and the handle lever 60 is operated by the second locking protrusion 61c. This is to be done.

Next, the handle lever 60 is secondarily operated by the engaging force of the second locking protrusion 61c. If the second locking protrusion 61c is broken in this state, the handle connecting shaft 61 and the lever as shown in FIG. 14B. By the leaf spring 64 which catches the connection of the blade | wing 62 and 63 by the elastic force to the said latching jaw 61d, it can be guaranteed by a 3rd safe operation.

In FIG. 9, reference numeral 80 denotes a dead bolt lock.

The dead bolt lock 80 is the operation shaft when the door lock is rotated in the locked state in the counterclockwise direction in the state in which the door lock is released (dead bolt 20 is retracted state) The dead bolt 20 is moved forward by interlocking the 40.

The dead bolt lock 80 is engaged with the teeth 43 of the operating shaft 40 in a hinged state to the guide shaft 30 as shown in Figure 9, the lock of the handle lever 60 The operation is switched to the lock rotation operation of the operation shaft 40 as shown in Fig. 10A.

The dead bolt lock 80 is a pair of divided pieces (81, 82) and the divided pieces are divided to absorb the reaction force buffer when a reaction force failure occurs during the locking operation of the dead bolt 20, It consists of a torsion spring (83) for joining the joint surfaces of (81,82) with an elastic force, the divided pieces (81,82) are hinged to the bushing (84) inserted into the guide shaft (84) The dividing surfaces of the divided pieces 81 and 82 are in close contact with the elastic force by the torsion spring 83 force.

As shown in FIGS. 8 and 9, the torsion spring 83 has one end connected to the engaging jaw 81a of the one side split piece 81, and the other end of the torsion spring 83 has the engaging jaw 82a of the other split piece 82. Is connected to. Therefore, the pair of divided pieces 81 and 82 are provided so that the divided surfaces come into contact with the torsion spring 83 force.

The one side of the divided piece 81 is provided with a protruding arc-shaped support jaw 81b, the inner surface side of the support jaw 81b, bearings provided on the inner side of the tip of the lever blade 62, as shown in Figure 10a, 10b 65 is located, the bearing 65 is a dead bolt fastener while rolling the handle lever 60 in the counterclockwise direction while rolling the inner surface of the support jaw 81b of the dead bolt fastener 80 The 80 is rotated clockwise.

The outer peripheral surface of the split piece 82 on the other side is provided with a tooth portion 82b which meshes with the tooth portion 43 of the operation shaft 40.

Therefore, when the dead bolt 20 is in the unlocked state as shown in FIG. 10B, when the handle lever 60 is rotated counterclockwise, the dead bolt lock 80 rotates clockwise about the guide shaft 30 and simultaneously. The operation shaft 40 rotates counterclockwise in engagement with the dead bolt lock 80 through the tooth coupling, whereby the dead bolt 20 is advanced again to a locked state.

However, if the dead bolt 20 moves forward from the case 10 and encounters an obstacle (for example, the door wall surface) at any moment, sudden force is transmitted to the handle lever 60 and the dead bolt locking device 80 suddenly. do. However, in the present invention, the one side divided piece 81 of the dead bolt lock 80, which has been integrated, overcomes the torsion spring 83 force from the other divided piece 82, and performs a shock absorbing function.

Reference numeral 90 in FIG. 17 denotes a protrusion bundle operation unit.

The protrusion bundle manipulation unit 90 engages or releases the manipulation shaft pivoting lever 50 and the protrusion bundle 44 by raising or lowering the posture of the protrusion bundle 44.

The protrusion bundle manipulation unit 90 includes a protrusion bundle manipulation tool 100, a pressing hole 102, a driving motor 104, a trigger wheel 109, a trigger 110, and a trigger rotating hole 112. .

The protrusion bundle manipulation tool 100 is inserted into the shaft 11 to be slidably moved up and down around the rotational trajectory of the protrusion bundle 44 as shown in FIG. 6, and the dead bolt 20 is locked. Lower the posture of the protrusion bundle 44 to release the coupling between the protrusion bundle 44 and the operation shaft pivot lever 50, and when the trigger 110 is activated (when a driving signal is input to the driving motor), the protrusion Lifting the posture of the bundle 44, the protrusion bundle 44 is coupled to the operating shaft pivoting lever (50).

Accordingly, the protrusion bundle 44 is provided with a support jaw 44a at the lower end as shown in FIG. 6, and the support jaw 44a is pressed against the lower pressing surface 100a of the protrusion bundle manipulation tool 100. .

When the dead bolt 20 is in the door lock state (when the dead bolt is advanced), the upper surface of the protrusion bundle 44 maintains a plane which is lower than or substantially the same as the upper surface of the boss portion 41 of the operation shaft 40. When the protrusion bundle 44 is separated from the pressing surface 100a of the protrusion bundle operating tool 100, the upper surface of the protrusion bundle 44 protrudes a predetermined amount higher than the upper surface of the boss portion 41 by the force of the spring 45. It is to maintain the posture.

The pusher 102 is capable of pressing the protrusion bundle manipulation sphere 100 with a constant spring 101 force and releasing the pressing force of the protrusion bundle manipulation sphere 100 by the trigger 110.

The pusher 102 is hinged to the pivoting jaw 103c of the base 103 disposed on one side of the case 10 so as to be rotatable up and down, and the pusher 102 is a spring 101. The rotational force is added downward by the force) to press the protrusion bundle operating tool 100 downward.

The base 103 is equipped with a drive motor 104 that rotates forward and reverse by an electric drive signal to operate the trigger 110, and a worm 105 is installed on the rotation shaft of the drive motor 104. And a worm gear 107 rotatably installed on the base 103 at one side of the worm 105 and engaged with the worm 105, and rotatably coaxially with the worm gear 107. The trigger wheel 109 is installed and the forward and reverse rotation amount is limited by a predetermined amount by the elastic force of the spring 108 is disposed, the upper surface of the trigger wheel 109 is formed with a trigger engaging groove 109a cut in the circumferential shape It is.

The spring 108 is inserted into the shaft portion 107a of the worm gear 107, and both ends of the spring 108 are alternately connected to the protrusion 107a of the worm gear 107, and the trigger wheel 109 A locking jaw 109b formed at the bottom of the spring is sandwiched between both ends of the spring 108.

Therefore, when the worm gear 107 rotates the trigger wheel 109 in one direction in a fixed state engaged with the worm 105, the spring 108 is repulsed and the amount of rotation of the trigger wheel 109 is limited.

The trigger 110 is arranged to be slidably movable on the upper surface of the trigger pivot 112, and is pushed in the opposite direction of the trigger by the force of the spring 111.

The trigger 110 is fitted to the protrusions 112a and 112b protruding from the upper surface of the trigger rotating hole 112, the spring 111 is inserted into the long hole (110a) through the trigger 110, the spring One end of the 111 is pushed against the one side protrusion 112a of the trigger rotating hole 112, and the other end of the spring 15 is pushed against the inner wall of one side of the long hole 110a.

In addition, the trigger 110 is provided with an inclined jaw 110b at the front end to lift the pusher 102 upward.

Therefore, in the state where the protrusion bundle 44 lowers its posture, that is, even when the rotation lever 50 is rotated, the operation shaft 40 cannot be rotated in any direction. Pressing the projection bundle 44 downward by the force of the side spring 101, the rotational rotation force is added to the trigger rotating hole 112 in the clockwise direction by the force of the spring 113, the trigger 110 side The locking jaw 110c is pushed toward the circumferential surface side of the trigger wheel 109.

In this state, when the driving motor 104 is driven, the worm gear 107 meshed with the worm 105 and the trigger wheel 109 rotate in conjunction with each other, and the trigger is engaged in the trigger engaging groove 109a of the trigger wheel 109. 110 is engaged, and win the spring 111 force and pull the trigger 110.

When the trigger 110 is caught and raised, the pressing hole 102 is lifted and rotated, and the protrusion bundle manipulation tool 100 rises by the force of the protrusion bundle 44 side spring 45, and the attitude of the protrusion bundle 44 is increased. The upper surface of the protrusion bundle 44 rises up a predetermined amount above the upper surface of the boss portion 41 of the operation shaft 40, and thus, the angle conversion port 70 interlocked with the handle lever 60 by operating the handle, It is possible to convert the locked state of the dead bolt 20 to the unlocked state by rotating the operating shaft 40 via the operating shaft pivoting lever 50 and the protrusion bundle 44.

On the other hand, the present invention is a projection (66) provided on the rotation end side of the handle lever 60 to release the trigger 110 during the rotation operation to unlock the handle lever 60 in the locked state of the trigger (110) It is provided with an operating pin 115 for rotating the trigger rotating hole 112 in the counterclockwise direction, the operating pin 115 is provided to the guide hole 112a penetrated through the free end of the trigger rotating hole 112 Protrudingly, the actuating pin 115 is supported by a spring 116 having one end connected to the trigger pivot 112 and the other end connected to the actuating pin 115.

Therefore, the actuating pin 115 is pushed clockwise about the hinge shaft 15 of the trigger rotating hole 112 at all times by the force of the spring 116 as shown in FIG.

Accordingly, when the handle lever 60 is operated clockwise as shown in FIG. 19B while the trigger 110 is pulled on the trigger wheel 109 and the trigger rotation hole 112 is rotated clockwise, the handle lever 60 side The projection 66 pushes the actuating pin 115 and the trigger pivot 112 rotates counterclockwise about the hinge axis 15 via the force of the spring 116, so that the trigger 110 triggers the trigger wheel. It is possible to escape from 109.

The trigger pivoting hole 112 receives the trigger 110 and manipulates the handle lever 60 in the release direction to make the latch bolt 25 unlocked. For releasing the 110, it is hinged to the hinge shaft 15 of the base 102 and is supported by the force of the spring 113. Accordingly, the trigger pivot 112 is applied with a rotational force clockwise about the hinge axis 15 and is pushed against the engaging jaw 103a of the base 102.

On the other hand, the present invention includes a dead bolt detection unit 110 for checking the lock / unlock state of the dead bolt (20).

When the dead bolt detecting unit 110 is L as shown in Fig. 15, the reciprocating operating section of the dead bolt 20 is at least on / off when the dead bolt 20 is smaller than L and moved more than L / 2. In order to be detected, a switch operating tool 120 is disposed at the rear of the dead bolt 20, and the switch operating tool 120 detects the lock / unlock state of the dead bolt 20 as on / off. The switch 123 is provided in the base 103.

The switch operating port 120 has a guide protrusion (120b) on the bottom to receive the guide of the guide hole (10a) of the case 10, and guides the operating jaw (23) formed at the rear end of the dead bolt 20 It is provided with a guide hole 120a.

In addition, the switch operating tool 120 is supported by pressing the steel ball 122 with an elastic force through the spring 121, the steel ball 122 is caught by the two steel ball insertion hole (10b).

Therefore, the operation principle of the switch operation tool 120 to turn on / off the detection switch 123 is as follows.

The operating section of the dead bolt 20 is referred to as L (long hole length of the dead bolt), the length of the guide hole 120a of the switch operating tool 120 is referred to as A, and the switch operating tool 120 is moved substantially. If the possible distance is B, the L operating section can be expressed as the sum of A (non-switching section) and B (switching section), and L> A <L / 2.

Therefore, when the dead bolt 20 is in the door lock state (advanced state) as shown in FIG. 16A, the switch operating tool 120 is in the position of P1, and in this case, the switching is turned on. If the dead bolt 20 retreats in this state, the switch operating tool 120 does not operate as much as the length A. When the dead bolt 20 retracts by the length A, and then passes over the dead bolt 20, the switch operating tool 120 is retracted by the remaining B section and switched off as shown in FIG. 16D.

In this state, when the dead bolt 20 advances to the locked state in the opposite direction, the dead bolt 20 does not switch off during the A section. When the section A section is exceeded, the micro switch 123 is switched on while the switch operating section 120 moves section B.

As described above, in the present invention, the on / off detection of the dead bolt 20 does not require the use of two switches, as the switching operation occurs only when the dead bolt 20 is operated over a predetermined period.

On the other hand, the present invention is a trigger detection switch 124 for detecting the operating state of the trigger 110 on / off is fixed to the hinge axis (103b) of the trigger wheel 109, the trigger detection switch 124 The on / off operation is performed by the switch operation piece 110d of the trigger 110.

That is, the trigger detection switch 124 is driven when the drive motor 104 receives the drive signal and the trigger 110 is engaged with the trigger wheel 109, and operates from the off state to the on state, and the trigger 110 again. Is sensed to deactivate from the trigger wheel 109 from the on state to the off state.

On the other hand, the present invention is mounted on the base 103 in order to check the operating state of the protrusion bundle 44, the protrusion bundle for detecting the up, down operation operation of the protrusion bundle manipulation tool 100 on / off. The sensing switch 125 is further added.

The protrusion bundle detection switch 125 is in an on state when the protrusion bundle 44 is in a falling position, and detects an off state when the protrusion bundle 44 is in a rising position.

The operating state of this embodiment configured as described above will be described.

First, FIG. 11 is a state in which the dead bolt 20 and the latch bolt 25 protrude a predetermined amount to one side surface of the case 10 and have a door lock.

In this state, the bottom surface of the protrusion bundle 44 maintains a posture lowered near the bottom of the case 10 so that the top surface of the protrusion bundle 44 is flush with the top surface of the boss 41 of the operation shaft 40. If it is.

The trigger 110 maintains the retreat posture as shown in FIG. 19A and is in the trigger preparation stage.

In this case, the dead bolt detection switch 123 is in an on state as shown in FIG. 16A, the trigger detection switch 124 is in an off state, and the protrusion bundle operating switch detection switch 125 is in an on state. .

In this state, the operation of the key and the electric operation without using the key and the operation state of unlocking the door using the handle will be described.

When operating with the key 1, when the operating shaft 40 rotates clockwise as a result of the key, the dead bolt 20 caught by the arm 42 of the operating shaft 40 retreats to the right. Move. At this time, when the critical position (the middle position of the moving section of the dead bolt) is exceeded by the elastic repulsive force of the spring 35 connected to the dead bolt 20, the dead bolt 20 completes the retraction movement by the spring 35 force. The dead bolt detection switch 123 is turned off as shown in FIG. 16d to detect the release of the dead bolt 20.

The dead bolt lock 80 engaged with the operation shaft 40 at the same time as the clockwise rotation of the operation shaft 40 rotates about 45 degrees counterclockwise around the guide shaft 30 as shown in FIG. , The projection bundle 44 is released from the pressing force of the projection bundle manipulation sphere 100 to maintain the protruding posture and stay in the position of 90 degrees from the original position. At this time, the outer circumferential surface of the bearing 65 at the tip of the handle lever 60 is in contact with the inner side of the engaging jaw 81b of the one-side partition piece 81 of the dead bolt lock 80.

When the handle lever 60 is rotated in the clockwise direction by operating the handle 3 in this state, the latch bolt 25 retreats in conjunction with the handle lever 60 to simultaneously move the handle lever 60. The furnace operation shaft rotation lever 50 is interlocked by 90 rotations, and the spring 132 is compressed while the pressure port 131 retreats.

In this state, when the dead bolt 20 and the latch bolt 25 are both unlocked and the handle is pulled out, the door is opened.

Later, when the handle is released, the latch bolt 25 is advanced again by the elastic restoring force of the latch bolt 25 side spring 26 and the pressure port 131 side spring 132 to protrude from the case 10 and operate. The axis pivot lever 50 returns to its original position again.

In this state, if the dead bolt 20 is advanced again to be in the locked state, the locked state can be obtained as the same result by selecting either the key operation or the handle operation.

For example, when the manipulation shaft 40 is rotated counterclockwise with the key, the arm 42 of the manipulation shaft 40 moves forward of the dead bolt 20 to lock. In this case, the dead bolt lock 80 rotates clockwise about the guide shaft 30 in association with the rotation of the operation shaft 40.

As another example, when the handle lever 60 is rotated counterclockwise with the handle, the handle lever 60 rotates the dead bolt lock 80 in a clockwise direction, and the handle lever 60 rotates in the clockwise direction. The interlocking operation shaft 40 rotates counterclockwise in the opposite direction so that the dead bolt 20 moves forward to lock.

If the dead bolt 20 encounters an obstacle while the dead bolt 20 moves forward when the locking operation is performed by the handle, the dead bolt 20 transmits the operating force of the handle lever 60 to the operation shaft 40. The bolt lock 80 may be operated to overcome the force of the spring 83 around the guide shaft 30 to buffer the impact force of the dead bolt 20.

(2) In case of using handle after electric operation

As shown in FIG. 11, when a driving signal is applied to the driving motor 104 in a state in which the dead bolt 20 and the latch bolt 25 are forward locked, the driving motor 104 rotates forward several tens of times and the worm 105 and the worm gear are rotated. 107 rotates in the engaged state, and the trigger wheel 109 connected to the worm gear 107 via the spring 108 force rotates several times in the clockwise direction.

As the trigger wheel 109 is rotated, the locking jaw 110c of the trigger 110 is hooked to the locking groove 109a to overcome the force of the spring 111 and pulls the trigger 110. At this time, the trigger detection switch 124 is turned on.

By the forward operation of the trigger 110, the pressing hole 102 is rotated upwards to overcome the force of the spring 101, and at the same time, the protrusion bundle operating port 100 is applied to the force of the protrusion 44 side spring 45 Ascending upward by the protrusion bundle 44 maintains the posture protruding upward. That is, when the lock release driving signal is applied to the driving motor 104, the protrusion bundle 44 maintains an upward position, and the upper surface of the protrusion bundle 44 protrudes a predetermined amount on the upper surface of the boss portion 41 of the operation shaft 40. The protrusion bundle 44 is located on the front surface of the locking jaw 51 of the operating shaft pivoting lever 50.

When the handle lever 60 is rotated clockwise by operating the handle in this state, the latch bolt 25 and the dead bolt 20 interlocked with the handle lever 60 can be simultaneously retracted.

That is, when the handle lever 60 is rotated in the clockwise direction in FIG. 11, the rotational force of the handle lever 60 rotates the angle conversion hole 70 along the guide hole 13 of the case 10, and the angle conversion hole The operating shaft pivoting lever 50 hinged to the 70 rotates the protrusion bundle 44 to the locking jaw 51 so that the operating shaft 40 rotates clockwise, and the dead bolt lock 80 counterclockwise. The dead bolt 20 is retracted while rotating in the direction to unlock.

At the same time, the handle lever 60 side projection 66 pushes the actuating pin 115 in the direction opposite to the force of the spring 116 as shown in FIG. 19B, whereby the actuating pin 112 is assembled with the actuating pin 115 assembled. ) Is rotated counterclockwise around the hinge shaft 15, the locking jaw (110c) of the trigger 110 is mounted on the trigger turning hole 112 as shown in Figure 19c is released from the trigger wheel 109 and at the same time The trigger 110 returns to its original position by the force of the spring 111.

At this time, the operation shaft 40 is rotated at an angle larger than the operated angle of the handle lever 60. This is because the length of the linear component connecting the operating shaft rotation lever 50 and the handle lever 60 is gradually increased by the angle conversion port 70.

Therefore, in the present invention, even when the handle is turned only about 30 degrees, the dead bolt 20 can be retracted to release the locked state.

When the handle is released in this state, the handle lever 60 is rotated counterclockwise by the force of the latch bolt 25 side spring 26 and the pressure port 131 side spring 132 to return to the original position, and the latch bolt ( 25) Advance.

In this state, when the handle lever 60 is rotated counterclockwise by operating the handle, the dead bolt lock 80 rotates clockwise about the guide shaft 30, and the dead bolt lock 80 The operating shaft 40, which is engaged to the rotating shaft, rotates in a counterclockwise direction, and the dead bolt 20 moves forward to make a locked state, and the operating shaft pivoting lever 50 rotates clockwise to return to its original position.

At this time, the protrusion bundle 44 lowers the posture again through the bottom of the protrusion bundle manipulation tool 100 with the rotation of the operation shaft 40. In other words. The upper surface of the protrusion bundle 44 stays at a level substantially coincident with the upper surface of the boss portion 41 of the operation shaft 40.

Accordingly, in the present invention, even if the drive motor 104 does not receive the trigger drive signal, even when the handle is operated, the operating shaft pivot lever 50 does not operate the protrusion bundle 44 and turns to the dead bolt 20. Can't make it to a state.

On the other hand, in the present invention, if the door is not opened while the trigger 110 is raised, that is, the handle is not operated, the drive motor 104 is rotated in a few seconds or several tens of seconds. When the driving motor 104 rotates in reverse, the trigger wheel 109 also rotates in reverse, and the trigger 110 returns to its original position and lowers the posture of the protrusions 44 to the bottom of the case 10 to lower the operation shaft 40. It makes it impossible to operate. This can be recognized by checking the time that the switches 124 and 125 do not change in the on and off states, respectively.

In the present invention operated as described above, the dead bolt 20 can be locked / unlocked by the handle by controlling the posture of the protrusion bundle 44 mechanically through the electric driving method. That is, the door lock can be released only when the lock release signal corresponding to the encrypted input signal is input. Therefore, the input signal applied to the present invention may generate a drive signal of the drive motor 104 through various identification methods such as a method of matching numbers, a fingerprint recognition method, an iris recognition method, and the like.

In addition, since the present invention includes all the mechanical locking devices inside the lock case 10, the structure of the main body to which the lock case is mounted can be simplified, and thus, the design modification of the main body can be freely performed.

As described above, according to the door lock device of the present invention, an electrically driven mechanical mechanism is intensively included in the door lock case to easily change the structure of the door lock device body, thereby creating various functional designs and designs.

In addition, according to the present invention by changing the position of the door lock case only can be installed regardless of the opening and closing direction of the door.

In addition, according to the present invention, even when an impact is applied to the dead bolt when the door is locked, the impact can be buffered, so that the operation feeling is good and the damage of the parts can be prevented.

In addition, according to the present invention, even if breakage occurs by forcibly manipulating the operation handle from the outside provides an advantage that can be released to unlock the door as well as the protection of the remaining parts.
