That is, in the conventional apparatus, the configuration for operating the dead bolt 47 and the configuration for operating the latch bolt 50 occupy separate spaces, and the solenoid 17 is the case 1 of the outdoor unit. The inside size increases the size of the outdoor unit, and the overall size increases due to many parts for transmitting the driving force of the solenoid 17 into the back set.

In addition, the conventional apparatus has a large number of parts and a device for solenoid operation is relatively complicated, so that not only the parts production process is complicated but also the assembly process is complicated and a lot of failures occur.

In particular, when assembling the pin 25 connecting the indoor unit, the outdoor unit, and the back set and the center of the parts to be connected thereto are not exactly aligned, the installation of the door lock device is difficult to install. When the center is twisted by the door lock device is not opened and closed well.

In addition, since the handle portion of the handle is protruded outwardly, when too large force is applied from the outside, the handle may be damaged or the connection state with other parts may be damaged.

In addition, there is a problem that the last operation when opening and closing the door is more cumbersome than necessary.

Accordingly, an object of the present invention is to solve the conventional problems as described above, and to provide a light and short door lock device as a whole.

Another object of the present invention is to provide a door lock device with a simpler configuration and easier installation.

Still another object of the present invention is to provide a door lock device with a more simplified operation for opening and closing a door.

Still another object of the present invention is to provide a door lock device in which the handle is not broken or broken even when excessive force is applied to the handle.

In addition, the back set 300 is installed inside the door and includes a latch bolt 330 and a dead bolt 340 for opening and closing and locking / unlocking the door. In addition, the inner unit 200 is installed on the inner surface of the door, and is provided with a structure for operating the door from the inside. The inner unit 200 is almost identical in configuration to the out unit 100.

First, the configuration of the out unit 100 will be described. The outer case 110 shields the components constituting the out unit 100 from the outside. The outer case 110 is fixedly installed on the outer surface of the door. The upper case of the outer case 110 is provided with a key input unit 112 for inputting a password, the lower end is formed with a through-hole 114 through which the rotary drive unit 122 of the handle 120 is installed.

As shown in FIG. 8, the handle 120 is formed such that the handle portion 121 and the rotation driving portion 122 are perpendicular to each other. The handle portion 121 is a portion that the user grasps by hand to operate the door lock device, the rotary drive portion 122 is rotated integrally with the handle portion 121 to transmit power to operate the opening and closing of the door. That's the part.

The rotary drive part 122 is formed in the central portion of the through-hole 124, the key cylinder 160 to be described below is located, the engaging projection 126 is formed at both edges of the end. The coupling protrusion 126 has a trapezoidal cross section. In addition, the installation end 125 for the installation of the return member 128 as shown in Figure 9 is formed at the end of the rotary drive unit 122.

When the handle 120 is rotated in the clockwise direction on the drawing, the rotation driving unit 122 rotates in the clockwise direction to rotate the disk 130. When the disk 130 is rotated, the opening and closing member 140 is rotated by the driving plates 137 and 137 'of the disk 130, and the driving plates 146 and 146' of the opening and closing member 140 are rotated clockwise. 20A to 20B. 20A and 20B show that the driving protrusions 172 and 172 'of the cam 170 and the interlocking protrusions 182 and 182' of the plunger 180 operate in conjunction with each other.

That is, the handle 120 in the state of FIG. 20A (the state in which the handle 120 is horizontally positioned and only the latch bolt 330 protrudes out of the back set 300 so that the user can freely open the door) When rotated about 45 degrees in the downward direction, the rotary drive unit 122 and the disk 130 of the handle 120 is interlocked and rotated together. When the disk 130 is rotated as described above, the disk 130 is positioned inside the through hole 142 of the opening and closing member 140 to be interlocked with the opening and closing member 140.

When the opening and closing member 140 is operated as described above, the driving plates 146 and 146 'rotate the latch interlock lever 310 in the back set 300 counterclockwise. When the latch interlock lever 310 is rotated, the driving arm 314 drives the driving bar 332 of the latch bolt driving frame 331 so that the latch bolt driving frame 331 moves in the right direction on the drawing. The latch bolt 330 is accommodated in the back set. This state is the state of FIG. 20B, and when the handle 120 is pulled out, the door is opened.

On the other hand, the latch bolt 330 is always supported to protrude out of the case 301 by the protruding spring 333, so when the user releases the handle 120, the handle 120 is the return member ( The latching lever 310 and the latch driving frame 331 are moved to the left side of the drawing by the restoring force of the protruding spring 333, and the latching bolt 330 is moved to the case 301. Protrude to the outside. When the door is closed again in such a state, the latch bolt 330 is pushed and pushed by the door frame (not shown) and received inside the case 301, and then again by the restoring force of the protruding spring 333. It protrudes so that the door does not open arbitrarily.

Secondly, the key is used to lock or unlock the door. In this case, the operation is performed once the door is closed. Here, the locked state of the door refers to the state of FIGS. 20C and 20D, that is, the dead bolt 340 protrudes out of the back set 300. At this time, it can be seen that the plunger 180 is placed in the horizontal direction in common in both drawings.

That is, the operation is performed by the user rotating the key cylinder 160 using the key from the outside or rotating the summton 221 inside the key. First, when the user operates the key cylinder 160 using a key from the outside, the cam 170 installed at the rear end of the key cylinder 160 rotates together to rotate the plunger 180. As such, when the plunger 180 is rotated, the connecting pin 190 inserted into the plunger 180 is rotated together.

Accordingly, the dead linking lever 320, through which the connecting pin 190 is installed, is rotated counterclockwise by the connecting pin 190 in the bag set 300, and the switching arm 322 is rotated. The dead drive frame 342 is moved in the left direction on the drawing. Therefore, the dead bolt 340 provided at the front end of the dead driving frame 342 protrudes to the outside of the case 301 to be in the state of Figure 20c. In this case, the door is locked.

On the other hand, even when the user rotates the Sumton 220 therein, the connecting pin 190 is rotated by the Sumton 220 and the operation thereafter is as described above.

Lastly, the key input unit 112 inputs a password and the handle 120 opens the door. First, in FIG. 18, the solenoid 350 is turned off. At this time, the solenoid 350 is turned off so that the switching lever 352 is rotated in a clockwise direction with respect to the hinge shaft 353. Therefore, the pressing protrusion 352P of the switching lever 352 does not press the interlocking protrusion 358 of the locking pin 356 so that the locking pin 356 is not rotated about the hinge pin 357. It is not in a state.

Therefore, when the handle 120 is manipulated, the driving plates 146 and 146 'of the opening and closing member 146 can be freely moved along the guide slot 305 for a predetermined period. Accordingly, the latch bolt 330 may be interlocked with the operation of the handle 120 to be accommodated in the back set 300 as illustrated in FIG. 20D. However, even when the latch bolt 330 is operated as described above, the dead bolt 340 protrudes, and thus the locked state of the door is continuously maintained.

Meanwhile, when the user inputs a password through the key input unit 112 in the state of FIG. 18, the solenoid 350 is operated. Therefore, the switching lever 352 is rotated counterclockwise around the hinge axis 353, the pressing projection 352P is pressed by the interlocking projection 358 of the locking pin 356.

Accordingly, the locking pin 356 is rotated clockwise about the hinge axis 357 to be in the state of FIG. In this case, one side of the driving plates 146 and 146 ′ of the opening and closing member 140 is caught by the locking portion 359 of the locking pin 356. Therefore, in this state, when the user rotates the handle 120 about 45 ° clockwise in a horizontal state with respect to the ground, the driving plate (146,146 ') is rotated, the latch interlock lever 310 ) And the dead interlock lever 320 to allow the latch bolt 330 and the dead bolt 340 to be received into the back set 300 to open the door.

At this time, the dead interlocking lever 320 is operated together is the interlocking protrusion 358 of the locking pin 356 is pressed by the push protrusion 352P of the switching lever 352 of the locking pin 356 This is because the locking portion 358 is caught by the one side driving plate 146. That is, the driving arm 146 rotates while the locking pin 356 rotates together, so that the switching arm 322 moves the dead drive frame 342 to the right on the drawing.

Meanwhile, the on state of the solenoid 350 is maintained only for a predetermined time (for example, about 3 seconds). That is, if a predetermined time passes after the user inputs the password, the user is automatically turned off so that the state in which the password is inadvertently released is not maintained.

20a, 20b, 20c, and 20d, as shown in FIG. 20a, 20b, 20c, and 20d, when the handle 120 is lowered by about 45 ° clockwise, the cam 170 is rotated together as shown in FIG. 330 protrudes from bag set 300.

In the locked state of the door, when the plunger 180 is rotated by the operation of the key or the summton 220, the interlocking protrusions 182 and 182 'are horizontally placed as shown in FIGS. 20C and 20D. In the unlocked state of the door, when the plunger 180 is rotated by a key or the summton 220, the interlocking projections 182 and 182 'are perpendicular to the ground surface as shown in FIGS. 20A and 20B. It keeps rotating 45 ° counterclockwise.

The latch bolt 330 protrudes from the back set 300 when the driving protrusions 172 and 172 'of the cam 170 are vertically positioned as shown in FIGS. 20A and 20C. Also, the latch bolt 330 is accommodated in the back set 300 in a state in which the driving protrusions 172 and 172 'are rotated clockwise by 45 ° with respect to the line perpendicular to the ground surface as shown in FIGS. 20B and 20D. Will be.

On the other hand, when an excessive force is given to the handle 120, the handle 120 is rotated while overcoming the elastic force of the return member 128 and the coil spring 139. In this case, the protrusion 126 provided in the rotation driving unit 122 of the handle 120 is 45 ° from the start of rotation of the handle 120 while being coupled to the horizontal grooves 134 and 134 'of the disk 130. Rotate together enough. This is because the coil spring 139 exerts a force on the disk 130, so that the disk 130 is pushed in the direction of the handle 120.

However, if the handle 120 is rotated further while being given excessive force, the locking pieces 138 and 138 'of the disc 130 are formed on the stoppers 154 and 154' formed inside the cap 150. It can get stuck and no longer rotate. When a force is continuously applied to the handle 120 in such a state, the coupling of the protrusion 126 and the horizontal grooves 134 and 134 'which maintain the coupling between the disc 130 and the handle 120 is Is released. That is, as the protrusion 126 protrudes from the horizontal grooves 134 and 134 ′, the disc 130 is pushed while overcoming the elastic force of the coil spring 139. In this case, only the handle is rotated while the coupling between the disc 130 and the handle 120 is released. In this way, the handle 120 can be freely rotated more than 90 °.

At this time, if the handle 120 is rotated less than that 90 ° relative to the original state by the restoring force of the return member 128, when more than that when returned to the horizontal position opposite to the original position. Therefore, even when excessive force is applied to the handle 120, the handle 120 is not broken or the coupling between the handle 120 and other components is not damaged.

And in installing the door lock apparatus which concerns on this invention to a door, there exist the following convenient points. That is, in installing the door lock device, the connection between the rotation driving unit 122, the disk 130 (the plunger 180, the summton 220) and the opening / closing member 140 of the handle 120 should be straight. If they are not aligned in line with the installation conditions or during use, the installation of the door lock device becomes difficult, and after installation, the power transmission between them is not assured, so that the operation of the door lock device does not work properly.

However, in the present invention, the rotation drive unit 122 and the opening and closing member 140 of the handle 120 with respect to the disk 130 can move up, down, left and right, even if they do not exactly match the straight line door lock device There is no problem in operation and installation.

It has a margin to flow in one direction (up and down in this embodiment) in the coupling between the horizontal grooves (134, 134 ') provided in the disk 130 and the protrusion 126 of the rotary drive unit 122, In the coupling between the longitudinal slot 136 of the disk 130 and the engaging projections (144,144 ') of the opening and closing member 140 there is room to flow in a direction perpendicular to the above (left and right in this embodiment) Therefore, there is no problem in power transmission between them even if they are not in line on the same principle as the Ouldam coupling.

The door lock device according to the present invention as described in detail above does not occupy a lot of space to be installed in a light and small size as a whole, the installation of the principle of the Ouldam coupling is made easier to install, the convenience of operation You can expect a bigger effect.
