The present invention relates to a bidirectional door lock mobility, and more particularly, to a bidirectional door lock mobility which is capable of rotating between a handle block to which an outdoor handle shaft and an interior handle shaft are coupled, The door lock can be unlocked even when the shaft and the inner handle shaft are turned clockwise and counterclockwise.

Generally, the door lock mottis includes a latch bolt which is protruded and drawn into the side surface of the door by a rotating means such as a lever. The latch bolt is a means for preventing the door from automatically opening (i.e., performing only the function of closing), and is not a locking means. Accordingly, a door lock mothesis having a lock structure by a latch bolt and a dead bolt by providing a dead bolt that is locked and unlocked by a knob or a grip has been developed and used.

In addition, a digital door lock motor that can release a dead bolt by the power of a motor is developed and used by pressing a key input button on the outside of the door or using a safety key with a built-in semiconductor chip, and pressing a button inside the door. Such a digital door lock motis is convenient because it allows the dead bolt to be automatically moved to the locked position through the power of the motor after the door is closed even if the user forgets to lock the door. Of course, the digital door lock motes can also be keyed to release the dead bolt.

The demand for such a digital door lock motis is rapidly increasing as the user can unlock the key even if the user does not have a key and the recognition that the door is automatically locked and safe is convenient when the door is closed.

On the other hand, Korean Patent Laid-Open No. 10-2014-0111560 and the like disclose the prior art relating to door lock motis.

It is an object of the present invention to improve the durability of a door lock motice by reducing a load applied to a component that performs unlocking in both directions among parts of the door lock motice.

In order to achieve the above object, a door lock motor according to the present invention is a door lock motor that performs a function of locking or unlocking a door, wherein the door lock motor is coupled with an outdoor handle shaft and an indoor handle shaft, A handle block for drawing the latch bolt into the door lock motor according to the rotation of the handle shaft; Wherein the handle block includes a first handle block, a second handle block, and a third handle block and is coupled to each other, a panic engaging means is coupled to the periphery of the second handle block, A second handle engaging jaw formed on the second handle block and a latch engaging means engaging with a third handle engaging jaw formed on the third handle block are coupled to the second handle engaging jaw and the third handle engaging jaw, A ratchet pawl which is hooked on the handle hook and pulls the latch bolt into the door lock motor according to the rotation of the second handle block or the third handle block; And a latch link which is hooked by the latching means and pulls the latch bolt into the door lock motor according to the rotation of the second handle block or the third handle block.

Here, a second handle pressurizing protrusion is formed on one side of the second handle block, and the panic engaging means is rotated according to the rotation of the second handle block by being hooked on the second handle pressurizing protrusion, And a rotational force switching member for guiding the rotational force to the inside.

When the outdoor handle shaft is rotated in the clockwise direction, the third handle pressing blade formed at one side of the third handle block moves the latching thread arm to draw the latch bolt into the door lock, The third handle latching jaw rotates the latching means, and then the latching means rotates the latch link to draw the latch bolt into the door lock.

When the inner handle shaft is rotated in the clockwise direction, the second handle engaging jaw rotates the latch engaging means, and then the latch engaging means rotates the latch link to draw the latch bolt into the door lock, When the inner handle shaft is rotated in the counterclockwise direction, the second handle pressing blade formed at one side of the second handle block moves the latching thread arm to draw the latch bolt into the door lock.

The door lock motice according to the present invention has the following effects.

1 to 8, a bidirectional door lock motor according to an embodiment of the present invention includes a case, a body front 30, a latch bolt 100, a latch ring arm 180 A handlebar block 190, a rotational force switching member 270, a gear box 280, a deadbolt trebler 300, a deadbolt 310, a slider 320, and a PCB 330.

The case includes an outdoor side case 10 and an indoor side case 20, and protects the respective components of the door lock motis, and is mounted on the door. An outdoor handle shaft (not shown) capable of opening a door by operating a latch bolt 100 by a user outside the room is coupled to the outside of the outdoor side case 10, A key input unit or a card contact unit may be mounted. An interior handle shaft (not shown) capable of opening a door by operating a latch bolt 100 by a user is coupled to the outside of the indoor side case 20, and a knob for releasing the dead bolt 310 a knob or a button may be provided.

The body front 30 is formed to face the side of the outdoor side case 10 and the indoor side case 20, that is, a striker (not shown), and the latch bolt 100 and the dead bolt 310 An inlet hole is formed.

The latch bolt 100 is provided to prevent the door from being opened by itself, that is, to maintain the closed state of the door. When the door is closed in the open state, the portion contacting the striker is an inclined surface. The latch bolt (100) moves together with the latch shaft (130) coupled to the latch bolt (100). That is, the latch shaft 130 is inserted and coupled to one side of the latch bolt 100 through the latch bolt guide 120, the latch shaft 130 is wrapped around the latch spring 110, A latch plate 140 provided with a catching latch post 150 is engaged with an end of the latch shaft 130. [ Therefore, when an external force is applied, the latch link 160 engaged with the handle block 190 rotates and the latch bolt 100 is pulled into the door lock motor when the latch post 150 is pulled. When the external force is lost, The latch bolt 100 is advanced again by the resilient restoring force of the latch spring 110 supported by the bolt guide 120 and protruded to the outside of the door lock motis.

The latching arm 180 is supported within the door lock mothesis by the latching arm 150 coupled to the latching link 160 and the latching arm 160 and engaged with the handle block 190 and the latching post 150, (100) to be introduced into the door lock motice. The latch rail 180 has a latch post latching hole 181 and a handle block latching portion 182 formed therein. The latch post 150 is inserted into the latch post latch hole 181 to provide a space in which the latch post 150 can be advanced and retracted when the latch link 160 is rotated. A part of the structure of the handle block 190 is hooked on the handle block latching part 182 and the latching latch arm 180 linearly moves in the rotation direction of the handle block 190 according to the rotation of the handle block 190, Accordingly, the latch arm 180 is pulled out of the latch post 150 in the direction of linear motion, so that the latch bolt 100 can be drawn into the door lock motice.

The handle block 190 is coupled to the inner handle shaft and the outdoor handle shaft so that the latch bolt 100 and the dead bolt 310 are inserted into the door lock when the user rotates the indoor rotary shaft or the outdoor rotary shaft. The handle block 190 has a shape in which the second handle block 205 is sandwiched between the first handle block 195 and the third handle block 225 and the second handle block 205 is provided with a panic- And the third handle block 225 is further coupled with the latching means 255. In this way,

 The first handle block 195 is formed with a first coupling hole 200 having a polygonal shape and the second handle block 205 is formed with a second coupling hole 210 having a polygonal shape connected to an inner handle shaft The third handle block 225 is formed with a polygonal third coupling hole 230 having the same shape and size as the first coupling hole 200 and coupled to the outdoor handle shaft.

As a result, the handle shaft module (not shown) is coupled with the outdoor handle shaft coupled with the outdoor lever in the direction of the first handle block 195, which is the outdoor side, and the indoor handle shaft coupled with the indoor lever The outdoor handle shaft is seated in the third engagement hole 230 and the inner handle shaft is seated in the second engagement hole 210 through the third engagement hole 230. The size of the first coupling hole 200 and the third coupling hole 230 is designed to be larger than that of the second coupling hole 210. Therefore, when the inner handle shaft is rotated, the second handle block 205 is rotated without affecting the first engagement hole 200. [

When the outdoor handle shaft is rotated, the first handle block 195 is rotated while the second handle block 205 is stopped. At this time, since the first handle block 195 and the third handle block 225 are connected Rotate together. The third handle block 235 and the third handle presser blade 240 are formed on the third handle block 225 so that when the third handle block 225 is rotated, The third handle pressurizing blade 240 is rotated together. The third handle holding jaw 235 rotates the latching means 255 and the third handle pressing blade 240 pulls the latching arm arm 180 in accordance with the rotation of the third handle block 225, 180).

When the indoor handle shaft is rotated, the second handle block 205 connected to the indoor handle shaft rotates together. The second handle block 205 is formed with a second handle engaging jaw 215, a second handle presser blade 220 and a second handle presser protrusion 221 so that when the second handle block 205 is rotated, The second handle engaging jaw 215 rotates the latch engaging means 255 while the second handle engaging jaw 215 partially contacts the latch engaging means 255 and the second handle pressurizing wing 220 rotates the third engaging jaw 215, The latch pulls the ratchet arm 180 in the same manner as the handle pressurizing wing 240 to linearly move the ratchet arm 180 and the second handle pressing protrusion 221 rotates the rotational force switching member 270. [

The rotation of the first handle block 195, the second handle block 205 and the third handle block 225 described above causes the latch bolt 100 and the dead bolt 310 to rotate in the clockwise and counterclockwise directions, Will protrude and enter the door lock motice, which will be described in detail later in the operation.

The rotational force switching member 270 is in contact with the second handle pressing protrusion 221 to rotate the panic locking means 245 in accordance with the rotation of the second handle pressing protrusion 221 so that the dead bolt 310 enters the door lock motis . The rotational force switching member 270 is supported on the wall surface of the outdoor side case 10 by passing the center of rotation through the rotation support rod 275.

The gear box 280 is provided to rotate the driving gear 281 by transmitting the rotational force of a motor (not shown) through a reduction gear (not shown). The rotational force of the driving gear 281 is transmitted to the driven gear 290 engaged with the driving gear 281 and the deadbolt trever 300 can be rotated by a certain angle as the driven gear 290 rotates.

A driven gear 290 is coupled to the periphery of the deadbolt trever 300 so that the deadbolt 310 is locked or unlocked by rotating the slider 320 by the external force or the power transmitted from the drive gear 281 do. That is, the deadbolt trever 300 can be rotated by a knob or a key. When the driven gear 290 coupled to the deadbolt trever 300 receives the rotational force from the drive gear 281, the deadbolt trever 300 rotates It is possible.

Deadbolts are formed on one side of the deadbolt trever 300 and contact protrusions 301 are positioned on the upper surface of the deadbolts. That is, the deadbolt 301 is formed in the deadbolt treasure 300 like the deadbolt 302, so that the contact protrusion 301 and the deadbolt are in contact with each other. Accordingly, as the contact protrusion 301 rotates, the dead bolt receives the rotational force from the contact protrusion 301 and moves together with the dead bolt.

The contact protrusion 301 is located in the deadbolt seat mount portion 321 formed on the slider 320 and the dead bolt is pressed against the slider 320 by pushing the forward protrusion 322 or pulling the backward protrusion 323, And may be rotated by a predetermined angle by the lever catching bar 250 of the panic engaging means 245 coupled to the second handle block 205.

One side of the slider 320 is formed integrally with the dead bolt 310 and the dead bolt 310 is provided on the opposite side of the slider 320. The dead bolt is fixed to the root bolt mount 321, The forward and backward jaws 322 and 323 are formed at the front and rear sides, respectively. Therefore, when the deadbolt treble 300 is rotated by using the knob or key, or when the driven gear 290 engaged with the drive gear 281 rotates according to the driving of the motor (not shown) The slider 320 is advanced or retracted by pushing the forward protrusion 322 of the slider 320 or pulling the backward protrusion 323 while the contact protrusion 301 is rotated at a predetermined angle. As a result, the dead bolt 310 is locked or unlocked.

Between the latch bolt 100 and the dead bolt 310, there is provided an apparatus for automatically advancing the slider 320 by confirming the closed state of the door. In other words, a Hall IC (not shown) is provided in front of the PCB 330, and a magnet (not shown) is attached to the groove of the striker (not shown). When the door is closed, A power is generated in a motor (not shown) in the gear box 280 to rotate the driven gear 290 so that the contact protrusion 301 provided on the deadbolt treble 300 is rotated So that the slider 320 can be automatically closed. Also, the PCB 330 may include a photosensor 340 to determine whether the slider 320 is in a locked state or an unlocked state.

The door lock motis according to the embodiment of the present invention described above will be further described with reference to an operation process.

FIG. 9 is a view showing that the first handle block and the third handle block shown in FIG. 6 are rotated clockwise to unlock the latch bolt, FIG. 10 is a view showing the first handle block and the third handle block shown in FIG. 11 is a view showing that the handle block is rotated counterclockwise to unlock the latch bolt, Fig. 11 is a view showing that the second handle block shown in Fig. 6 is rotated clockwise to unlock the latch bolt 12 is a bottom perspective view of the door lock motor shown in Fig. 11, with the ratchet arm and the rotational force switching member removed, Fig. 13 is a view showing that the second handle block shown in Fig. 11 is rotated counterclockwise to release the latch bolt Fig.

Referring to FIG. 9, a description will be made of a process in which the latch bolt 100 is drawn into the door lock motor when the outdoor handle shaft rotates clockwise. As shown in FIG. 9, when the user rotates the outdoor handle shaft clockwise, the third handle block 225 coupled to the outdoor handle shaft rotates clockwise. At this time, since the latching means 255 is engaged with the periphery of the third handle block 225 but the latching means 255 is not coupled to the entire circumference of the third handle block 225, Only the third handle block 225 can be rotated within a predetermined angle when rotating in the direction. When the third handle block 225 rotates in the clockwise direction, the third handle pressurizing blade 240 formed on one side of the third handle block 225 is hooked to the handle block engaging portion 182, 180) in the direction of the arrow. The latch posts 150 engaged with the latch post latching holes 181 are also moved along the arrows along the latch arms 180 as the latch arm arms 180 are moved.

As a result, since the latch plate 140 coupled with the latch post 150 moves along the latch post 150, the latch plate 140 and the latch bolt 100 are drawn into the door lock motis, Since the latch bolt guide 120 is blocked from movement.

The position of the latch bolt 100 and the latch shaft 130 is restored according to the elastic restoring force of the latch spring 110 and the position of the latch plate 140 and the latch post 150 is also restored. At this time, the latch post 150 pushes the latching arm arm 180 backward, so that the position of the latching arm arm 180 is restored, and the handle block engaging portion 182 of the latching arm arm 180 moves to the third handle pressing wing 240) so that the position of the third handle block 225 is also restored.

Referring to FIG. 10, a description will be made of a process in which the latch bolt 100 is drawn into the door lock motor when the outdoor handle shaft rotates counterclockwise. 10, when the user rotates the outdoor handle shaft counterclockwise, since the third handle stop 235 formed on the third handle block 225 is in contact with the latching means 255, The third handle-holding jaw 235 pushes the latching means 255 counterclockwise. When the latching means 255 is rotated in the counterclockwise direction, the latch linking jaw 260 rotates the latch link 160. That is, the latch link 160 rotates clockwise about the latch link shaft 170. The latch link 160 pushes the latch link 160 and the engaged latch post 150 so that the latch post 150 is moved in the direction of the arrow in the latch post latching hole 181. 9, as the latch post 150 is moved, the latch shaft 130 and the latch bolt 100 are drawn into the door lock motice, and the latch spring 110 is compressed.

When the rotation of the outdoor hand shaft is released, the latch bolts 100 are operated in the reverse order by the elastic restoring force of the latch spring 110 so that the latch bolts 100 are pulled into the door lock motice, The block 225 is also restored in its position. As a result, if the dead bolt 310 is already in the doorlock motis, the door can be opened.

Referring to FIGS. 11 and 12, a description will be made of a process in which the dead bolt 310 and the latch bolt 100 are drawn into the door lock motor when the inner handle shaft is rotated in the clockwise direction. As shown in FIG. 11, when the user rotates the indoor handle shaft in the clockwise direction, the second handle block 205 coupled with the indoor handle shaft rotates the panchucking means 245. That is, since the second handle engaging jaw 215 formed on the second handle block 205 is in contact with the panic engaging means 245, the second handle block 205 is rotated clockwise, The panchucking means 245 is pushed up and the panchucking means 245 is also rotated in the clockwise direction.

A lever catching bar 250 is formed at an end of the panic catching means 245 and the lever catching bar 250 is in contact with the contact protrusion 301. [ The latching bar 250 pushes the contact protrusion 301 in the direction of the arrow as the panic latching means 245 is rotated so that the dead bolt formed at the lower end of the contact protrusion 301 is also moved in the direction of arrow So that the dead bolt arm 302 is seated from the forward protrusion 322 to the reverse protrusion 323. The slider 320 is moved in the direction of the arrow and the dead bolt 310 integrally formed with the slider 320 is inserted into the door lock motis inside .

11, a description will be given of a process in which the latch bolt 100 is also drawn into the door lock motor when the dead bolt 310 is drawn into the door lock motor. 12, the second handle block 205 coupled with the inner handle shaft is rotated clockwise to rotate the panic locking means 245 and the latching means 255, At the same time in the direction of the arrow. That is, the second handle catching jaw 215 is in contact with the panchucking means 245, and at the same time, the second handle latching jaw 215 is in contact with the latching means 255 as well. Therefore, the second handle stopping jaw 215 pushes up the latching means 255 as well as the panic latching means 245 together in the direction of the arrow.

When the latching means 255 is rotated, the latch bolt 100 is inserted into the door lock motis. That is, the latch engaging means 255 rotates the latch link 160 in the direction of the arrow about the latch link shaft 170, so that the latch link 160 pushes the latch post 150. Finally, the latch spring 110 is compressed with respect to the latch bolt guide 120, the latch shaft 130 is moved in the arrow direction, and the latch bolt 100 connected to the latch shaft 130 is inserted into the door lock motis . As a result, the door can be opened as the dead bolt 310 and the latch bolt 100 are drawn into the door lock motis.

When the rotation of the inner handle shaft is released, the structures that have been moved or rotated due to the elastic restoring force of the latch spring 110 move backward, and the latch bolt 100 protrudes.

Referring to FIG. 13, a description will be made of a process in which the dead bolt 310 and the latch bolt 100 are drawn into the door lock motor when the indoor handle shaft is rotated counterclockwise. 13, when the inner handle shaft is rotated in the counterclockwise direction, the second handle block 205 coupled with the inner handle shaft is rotated counterclockwise to rotate the turning force switching member 270. [ The second handle pressing protrusion 221 formed on the second handle block 205 pushes the rotational force switching member 270 so that the rotational force switching member 270 rotates about the rotational support rod 275 in the direction of arrow . At this time, since the panic locking means 245 is coupled to the periphery of the second handle block 205 but the panic locking means 245 is not coupled to the entire periphery of the second handle block 205, Only the second handle block 205 can be rotated within a predetermined angle when rotating in the direction.

When the rotational force switching member 270 is rotated, the panic locking means 245 which is in contact with the rotational force switching member 270 is pushed up, so that the panic locking means 245 is rotated in the direction of the arrow. 11, the lever catching bar 250 formed at the end of the panic catching means 245 pushes the contact protrusion 301 and the contact protrusion 301 is rotated, so that the dead bolt, The slider 320 is moved in the direction of the arrow, and the dead bolt 310 is inserted into the door lock motis.

13, the process in which the dead bolt 310 and the latch bolt 100 are simultaneously inserted into the door lock motice will be described. When the second handle block 205 is rotated counterclockwise as described above, the second handle pressurizing blade 220 formed on one side of the second handle block 205 pulls the latching arm 180. That is, since the second handle pressurizing vane 220 is hooked to the handle block engaging portion 182 of the latch arm 180, the second handle block 205 is moved in the arrow direction as it is rotated counterclockwise.

The latch post 150 and the latch plate 140 caught by the latch post latching hole 181 of the latching arm 180 are moved in the direction of the arrow along the latching arm 180 when the latching arm arm 180 is moved , Which is the same as the lead-in process of the latch bolt 100 previously. That is, the latch spring 110 is compressed with respect to the latch bolt guide 120, the latch shaft 130 is moved in the arrow direction, and finally, the latch bolt 100 connected to the latch shaft 130 is inserted into the door lock motor . As a result, the door can be opened as the dead bolt 310 and the latch bolt 100 are drawn into the door lock motis.

When the rotation of the inner handle shaft is released, the structures that have been moved or rotated due to the elastic restoring force of the latch spring 110 move backward, and the latch bolt 100 protrudes.

As described in detail above, the door lock motis according to the present invention can be used for both the left door and the excellent door without changing the structure of the door lock motice. In the door lock motor according to the present invention, the inner handle block 190 is coupled in a multi-stage, and the handle blocks 195, 205, and 225 are divided and coupled to the outdoor handle shaft and the indoor handle shaft.

At this time, the respective handle blocks 195, 205 and 225 are coupled with the engaging means 245 and 255 to rotate together with the handle blocks 195, 205 and 225 or with the exception of the engaging means 245 and 255 Only the handle blocks 195, 205 and 225 may be rotated. Therefore, the dead bolt 310 and the latch bolt 100 are unlocked by the two rotation patterns. That is, even if the outdoor handle shaft and the indoor handle shaft are rotated clockwise or counterclockwise, it is possible to unlock the same. This operation can be conveniently used by the user even if the handle of the door is an excellent door on the left side of the door or a left side door on the right side.

Further, in the case of the push-pull door lock motice, the door is pushed from the indoor side with respect to one door and pulled out from the outdoor side so that the door is opened. On the other hand, It is also possible to open it. Therefore, the present invention can be used in combination with the above two forms.

In addition, it has high durability. When a lock is released in both directions from the door lock mottice, a considerable load is applied to the components for pulling the latch bolt 100 and the dead bolt 310 when rotating the outdoor handle shaft or the indoor handle shaft in both directions, Lt; / RTI > As a result, there is a problem that the durability of the door lock mott is low. However, in the present invention, the rotation force switching member 270 pushes only the panchucking means 245 and rotates.

That is, only the load for performing the operation of pulling the dead bolt 310 into the door lock motis is applied to the rotational force switching member 270, and the operation for pulling the latch bolt 100 into the door lock motis is not performed, The latching arm (180) performs the pulling of the door (100) into the door lock motor. Therefore, the durability of the rotational force switching member 270 can be improved. Since the latch bolt 100 and the dead bolt 310 are separately provided to the inside of the door lock motice, no load is applied to only a specific component, so that there is less damage such as warping. Thus, the durability of the door lock motice great.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And additions should be considered as falling within the scope of the claims of the present invention.
