  As a result, the latch 51 is released from the rotation restriction by the pole 52 and returned to the rotation by the urging force of the torsion spring 53. When the latch 51 is moved away from the striker 56 by the force for opening the door, the latch 51 is rotated. While returning to motion, the hooked state with the striker 56 is released and the striker 56 is pulled away. That is, by the opening operation of the outside handle, the latched state of the latch 51 and the striker 56 can be released and the door can be opened.
[0040]
  The third operation is an operation that forms a locked state in which the latched state of the latch 51 and the striker 56 cannot be released by a lock knob operation in the vehicle. When the door lock device is in the unlocked state shown in FIG. 4, when the locking cable 63 is operated by the lock operation of the lock knob, the lock operation lever 24 rotates in the clockwise direction in the drawing, and the third engagement pin 27d. 4 to rotate the active lever 27 counterclockwise in the figure, and the open link 23 is connected to the open lever 41 as a fulcrum from the unlocking operation position (operation position forming the unlocked state) shown in FIG. It is tilted (moved) to the lock operation position (operation position forming the lock state) shown in FIG. For this reason, even if the open link 23 is operated by opening the inside handle or the outside handle, the open link 23 does not engage with the engagement piece 42a of the lift lever 42, and the lift lever 42 and the pole 52 do not rotate.
[0041]
  As a result, even if the inside handle or the outside handle is opened, an unlocked state in which the latched state of the latch 51 and the striker 56 can be released is not formed, and the locked state is maintained and the door is opened. There is no. When the open link 23 is in the locking operation position (when it is in the position shown in FIG. 5), the latching lever 31 faces the latching portion 31 c of the latching lever 32. Then, by the pivoting operation of the latching lever 32 in the clockwise direction in the drawing, it waits at a position where it can be latched on the latching portion 32c of the latching lever 32 (double lock operation position). Further, when the open link 23 is in the unlocking operation position (when it is in the position of FIG. 4), the latching lever 31 disengages its latching portion 31 c from the latching portion 32 b of the latching lever 32. Thus, even if the latching lever 32 rotates in the clockwise direction in the figure, it waits at a position where it cannot be latched by the latching portion 32c of the latching lever 32 (undouble lock operation position).
[0042]
  The fourth operation is an operation for forming the door lock device in a locked state and an unlocked state by rotating the key cylinder with the key blade outside the vehicle. In the door lock device, when the key cylinder is rotated by the key blade, the lever portion 28b of the key lever 28 rotates to rotate the idle lever 29, and the idle lever 29 is activated via the second engagement pin 27c. The lever 27 is selectively rotated to the unlocking operation position shown in FIG. 4 and the locking operation position shown in FIG. Thereby, the active lever 27 selectively moves the open link 23 to the unlocking operation position shown in FIG. 4 and the locking operation position shown in FIG. Therefore, the latching state of the latch 51 and the striker 56 is selectively set to an unlocked state that can be released by an opening operation of the outside handle and a locked state that cannot be released by rotating the key cylinder with the key blade. Can be formed.
[0043]
  The fifth operation is, for example, an operation in which the electric motor 25 is driven to form the door lock device in a locked state and an unlocked state by a remote control operation outside the vehicle of a lock / unlock switch provided on the key blade. is there. In the door lock device, when the lock / unlock switch of the key blade is operated, the electric motor 25 is driven to rotate forward to rotate the wheel gear 26 by a predetermined amount via the worm 25a, and the wheel gear 26 is rotated forward and backward. Then, either one of the engagement pins 26a and 26b is selectively engaged with the engagement recess 27a of the active lever 27 so that the active lever 27 is brought into the unlocking operation position shown in FIG. 4 and the locking operation position shown in FIG. Selectively rotate. Thereby, the active lever 27 selectively moves the open link 23 to the unlocking operation position shown in FIG. 4 and the locking operation position shown in FIG. Therefore, by operating the key blade lock / unlock switch, the latched state of the latch 51 and the striker 56 is selected between an unlocked state that can be released by opening the outside handle and a locked state that cannot be released. Can be configured.
[0044]
  In the sixth operation, when the door lock device is in a locked state where the latched state of the latch 51 and the striker 56 cannot be released (see FIG. 5), the unlocking operation is performed by opening the inside handle. This is an operation (one motion operation) in which the lock operation and the door opening operation can be performed continuously. In the door lock device, when in the locked state, the engagement arm portion 22b of the second inside lever 22 approaches the contact portion 24d of the lock operation lever 24 as shown in FIG. When the inside handle is opened in this state, the second inside lever 22 is rotated integrally with the first inside lever 21, and the lock operation lever 24 is pushed to rotate it counterclockwise in the figure. Then, the latch lever 31 is rotated together. As a result, the latch lever 31 is elastically abutted against the active lever 27 via the third engaging pin 27d received between the receiving portions 24b of the lock operating lever 24. Rotate in the direction.
[0045]
  As a result, the active lever 27 rotates from the lock operation position shown in FIG. 5 to the unlock operation position shown in FIG. 6 to bring the door lock device into the unlock state shown in FIG. As a result of the opening operation, the open link 23 is pushed up via the first inside lever 21, the lift lever 42 is rotated, and the pole 52 is rotated. Thereby, a door can be opened.
[0046]
  In the seventh operation, when the door lock device is in a locked state where the latched state of the latch 51 and the striker 56 cannot be released (see FIG. 5), the second lock that locks the locked state so as not to be released. This is an operation to make a state (double lock state). In the door lock device, when in the locked state, the hooked portion 31c of the hooked lever 31 faces the swing arm portion 32a of the hooking lever 32, and the hooking lever 32 rotates in the clockwise direction in the drawing. The operation waits so that it can be hooked on the latching portion 32b of the latching lever 32. Therefore, the double lock switch of the key blade is operated (remote control operation) to drive the electric motor 33 in the forward rotation direction, and the latch lever 32 is set from the unset position shown in FIG. 5 to the set shown in FIG. The latch lever 31 is latched by the latch lever 32 when it is rotated by a predetermined amount in the clockwise direction to the position. Thus, the latch lever 31 and the latch lever 32 form the door lock device in a double lock state shown in FIG.
[0047]
  In the door lock device, this double lock state cannot be released not only by the operation of the outside handle but also by, for example, an unauthorized unlocking operation on the door knob from the outside. In order to release this double lock state, the electric motor 33 is driven in the reverse rotation direction by a predetermined amount by a remote control operation. As a result, the latch lever 32 can rotate by a predetermined amount in the counterclockwise direction shown in FIG. 7, and the latch lever 31 can be latched to the latch portion 32b of the latch lever 32 as shown in FIG. It returns to the standby state (unset position of the latch lever 32). The waiting state of the latch lever 31 is a locked state as shown in FIG. 5 in the door lock device, and the unlocking operation by the key blade described above or the unlocking operation by the remote control operation of the electric motor 25 is performed as shown in FIG. The unlocked state shown in FIG.
[0048]
  The eighth operation is an operation in which the door lock knob is illegally unlocked from the outside when the door lock device is in the double lock state (see FIG. 7). When the door lock device is in the double lock state shown in FIG. 7, when the lock knob is unlocked, the locking cable 63 is operated, and the lock operation lever 24 rotates counterclockwise as shown in FIG. However, since the latching lever 31 is latched by the latching lever 32 and the integral rotation with the lock operation lever 24 is restricted (in other words, the lock operation lever 24 has its latching portion 24e. Therefore, the active lever 27 is not rotated in the clockwise direction in the drawing to shift to the unlocking operation position. For this reason, the door lock device is kept locked. In the door lock device, after the unauthorized operation is finished from the outside of the door lock knob, the lock operation lever 24 is rotated in the clockwise direction by the urging action from the latched lever 31, and the lock shown in FIG. Return to the operating position.
[0049]
  The ninth operation is an operation in which the inside handle is illegally opened from the outside when the door lock device is in the double lock state (see FIG. 7). This opening operation of the inside handle corresponds to the one-motion operation described in the sixth operation. In the door lock device, in the double lock state shown in FIG. 7, the engagement arm portion 22b of the second inside lever 22 approaches the contact portion 24d of the lock operation lever 24 as shown in FIG. ing. When the inside handle is opened in this state, the second inside lever 22 is rotated integrally with the first inside lever 21 to push the lock operation lever 24, and the lock operation lever 24 is moved as shown in FIG. It rotates counterclockwise in the figure. However, since the latching lever 31 is latched by the latching lever 32 and the integral rotation with the lock operation lever 24 is restricted (in other words, the lock operation lever 24 has its latching portion 24e. Therefore, the active lever 27 is not rotated in the clockwise direction in the drawing to shift to the unlocking operation position. For this reason, the door lock device is kept locked. In the door lock device, after the unauthorized operation of the inside handle is completed, the lock operation lever 24 is rotated clockwise by the urging action from the latched lever 31 to perform the lock operation shown in FIG. Return to position.
[0050]
  In the tenth operation, when the door lock device is in a double lock state in which the latched state between the latch 51 and the striker 56 cannot be released (see FIG. 7), the double lock state is released at once and unlocked. It is an operation to make. In the door lock device, in the double lock state shown in FIG. 7, the active lever 27 is in the lock operation position, and the projection 27 e approaches the swing arm 32 a of the latch lever 32. positioned. For this reason, if the unlocking operation by the key blade is performed, or if the electric motor 25 is reversely driven by the remote control operation, the door lock device can be formed in the unlocked state shown in FIG.
[0051]
  The above-described tenth operation is based on the assumption that an abnormality has occurred in the drive system of the electric motor 33, for example. When the door lock device is in a double-locked state, if the lock release operation is performed with the key blade, the key lever 28 rotates the active lever 27 clockwise through the idle lever 29 as shown in FIG. Further, when the electric motor 25 is driven in reverse rotation by the lock / unlock switch operation (remote control operation) of the key blade, the wheel gear 26 rotates counterclockwise as shown in FIG. 10, and the active lever 27 is moved as shown in FIG. Turn clockwise in the figure. When the active lever 27 is rotated in the clockwise direction in the figure, first, the projection 27e is brought into contact with the swing arm 32a of the latching lever 32 and the latching lever 32 is rotated in the counterclockwise direction in the figure to be covered. The latching state of the latching lever 31 with respect to the latching lever 32 is released. Next, the active lever 27 rotates the open link 23 to the unlocking operation position by further rotation, thereby bringing the door lock device into the unlocked state shown in FIG. Therefore, in the door lock device in the unlocked state, the door can be opened by the opening operation of the outside handle, as described in the second operation.
[0052]
  As is clear from the above description, in the door lock device, the latch 51 and the striker 56 can be locked so that the latched state cannot be released, and the latched state of the latch 51 and the striker 56 can be released. The operation to form a simple unlocked state, the operation to open and close the door in the unlocked state and the locked state, the operation to form the double locked state that cannot be released to the unlocked state, and the double locked state Although it has a function to perform various operations such as a release operation, it has a one-motion operation function particularly in an undouble lock state (a lock state by the first operation mechanism 20).
[0053]
  Such a one-motion operation function includes a latch lever 31 that rotates the second operation mechanism 30 in conjunction with the lock operation and the unlock operation of the lock operation lever 24 in the first operation mechanism 20, The latch lever 31 is provided with a latch lever 32 that swings by locking and unlocking operations of the remote control, and the second inside lever 22 of the first operating mechanism 20 and the second operating mechanism 30 are covered. Since the stop lever 31 is connected via the lock operation lever 24 so as to be interlocked, the one-motion operation function is provided by a simple means in the door lock device.
[0054]
  Further, in the door lock device, the latch lever 31 has an unlock function when the lock operation lever 24 is unlocked, and the latch lever 31 is in the double lock operation position. In the state of being latched and held by the state (the state shown in FIG. 7), even if the lock operation lever 24 is unlocked, the unlocking function cannot be obtained due to the idling operation as shown in FIGS. Therefore, the idle operation of the lock operating lever 24 does not apply an excessive force to the components such as the latch lever 31 and the latch lever 32, and prevents the components such as the latch lever 31 and the latch lever 32 from being damaged. can do.
[0055]
  In the door lock device, the latch lever 31 is made of a spring steel material (elastic material), and the latch lever 31 is latched and held by the latch lever 32 in the double lock operation position. In the state (the state shown in FIG. 7), the unlocking operation of the lock operating lever 24 is allowed by the elastic deformation of the latching lever 31, so that the latching lever corresponding to the latching lever 31 is made of an inelastic material. Compared to the case where the torsion spring is interposed between the latched lever and the lock operating lever 24 so that they can be interlocked, the operating mechanism can be configured with a small number of parts. it can.
