  The lock mechanism is interposed between the inside door handle lever 190 and the latch mechanism L, and can be switched between a locked state and an unlocked state. When the outside door handle OH or the inside door handle IH is operated to open in the unlocked state, the lock mechanism releases this to the latch mechanism L, thereby releasing the latch state and opening the door D in the opening direction. While allowing the movement, the latch mechanism L is maintained in the latched state even when the outside door handle OH or the inside door handle IH is operated to open in the locked state.

  The unlocked state of the lock mechanism is, for example, the state shown in FIG. 2. In this state, the lock lever 50 is disposed at the unlock swing position, and the link lever 60 is disposed at the link lever unlock swing position. The open lever 70 is disposed at a release position where the ratchet driving unit 73 is disposed close to and opposed to the lower end surface of the contact portion 39 of the ratchet lever 38.

  On the other hand, the lock state of the lock mechanism is, for example, the state shown in FIG. 23. In this state, the lock lever 50 is disposed at the lock swing position, and the link lever 60 is disposed at the link lever lock swing position. The open lever 70 is disposed at a non-released position where the ratchet driving unit 73 is out of the portion facing the lower end surface of the contact portion 39 of the ratchet lever 38 in close proximity.

  In the door lock device 1, the child lever 140 and the child pin 150 constitute a child lock mechanism.

  The child lock mechanism is interposed between the inside door handle lever 190 and the latch mechanism L and between the inside door handle lever 190 and the lock mechanism, and can be switched between a transmission state and a non-transmission state. It is. In the transmission state, when the inside door handle IH is operated to open, the child lock mechanism releases the latch state by transmitting this to the latch mechanism L, and allows the door D to move in the opening direction. Even when the inside door handle IH is operated to open in the non-transmitting state, the latching state of the latch mechanism L is maintained.

  The transmission state of the child lock mechanism is, for example, the state shown in FIG. 2. In this state, the child lever 140 is most clockwise with respect to the shaft center 140x so that the manual operation unit 144a is disposed at the child unlock position. The child pin 150 is arranged at the interlocking position.

  On the other hand, the non-transmission state of the child lock mechanism is, for example, the state shown in FIG. 22, and in this state, the child lever 140 is moved relative to the shaft center 140x so that the manual operation unit 144a is disposed at the child lock position. The child pin 150 is swung most counterclockwise, and the child pin 150 is disposed at the non-interlocking position.

  Next, the operation of the door lock device 1 having the above configuration will be described. Here, for convenience of explanation, the opening of the vehicle body B is closed by the door D (hereinafter, this state is referred to as an initial state of the door D), and the latch mechanism L is switched to the latched state, as shown in FIG. The main inside door handle lever 80 is disposed at the second position, the lock mechanism is switched to the unlocked state, the child lock mechanism is switched to the transmitting state, and the inside door handle IH is disposed at the unlocked position. The description will be made assuming that the door handle lever 40 is disposed at the initial position (hereinafter, this state is referred to as an initial state of the door lock device 1).

  When a person who gets on the vehicle opens the outside door handle OH from this initial state, the outside door handle lever 40 is centered on the axis of the outside door handle lever shaft 40X. 1, the counterclockwise rotation occurs, and the outside operation end 43 moves upward in FIG. As the outside operation end 43 moves, the link lever 60 and the open lever 70 move upward (in the release direction) as shown in FIG. 20, and the ratchet drive unit 73 of the open lever 70 moves to the ratchet lever 38. It abuts against the abutment portion 39 and is moved upward in FIG. As a result, even when the latch mechanism L is in the latched state, the latched state can be released, so that the door D can be opened and moved relative to the vehicle body B.

  Even when the link lever 60 moves upward as shown in FIG. 20, the link lever connection pin 53 a of the lock lever 50 only moves inside the connection hole 62 a of the link lever 60 with the movement. In addition, the lock lever 50 does not rotate around the axis 50x of the lock lever shaft 50X in accordance with the movement of the link lever 60 described above.

  Thereafter, when the person getting on the vehicle removes the opening operation of the outside door handle OH, the outside door handle OH is returned to the initial position by the biasing force of the outside door handle biasing spring, and the outside door As shown in FIG. 2, the outside door handle lever 40 returns to the initial position, and the link lever 60 and the open lever 70 return to the downward movement state shown in FIG. 2 by the biasing force of the handle lever biasing spring. It will be.

  By the way, as described above, when the door D is in the initial state and the door lock device 1 is in the initial state shown in FIG. 2, the person riding in the vehicle focuses on the axis of the inside door handle shaft IHX. 6, when the inside door handle operating portion IHa is rotated counterclockwise beyond the latched release position (latch release position) indicated by the two-dotted line to the full stroke position, the unlock position setting spring After the main inside door handle lever 80 swings clockwise in FIG. 21 centering on the shaft center 80x against the biasing force of 80s and the inside door handle linkage portion 82 is disposed at the third position. Therefore, it will be arranged at the maximum swing position.

  When the main inside door handle lever 80 swings as described above, the child pin 150 moves clockwise in FIG. 21 around the shaft center 80x while abutting against the connect pressure receiving portion 102 of the connect lever 100.

  The movement of the child pin 150 causes the connect lever 100 to rotate counterclockwise in FIG. 21 about the axis 100x of the connect lever shaft 100X.

  In addition, since the connect lever 100 rotates in the counterclockwise direction in FIG. 21 while its own connect pressing portion 103 is in contact with the outside pressure receiving portion 44, the outside operation end corresponds to the rotation of the connect lever 100. The part 43 will move upward in FIG. As the outside operation end 43 moves, the link lever 60 and the open lever 70 move upward (in the release direction) as shown in FIG. 21, and the ratchet drive unit 73 of the open lever 70 moves to the ratchet lever 38. This is in contact with the contact portion 39, and is moved upward in FIG. Then, while the ratchet drive unit 73 is moving upward, the latch state of the latch mechanism L is released, and the door D can be opened and moved relative to the vehicle body B. In the door lock device 1, as described above, the rotational position of the inside door handle IH that releases the latch mechanism L in the latched state is referred to as a latched release position as shown in FIG. The rotational position of the main inside door handle lever 80 when is located at the release position is referred to as a third position. Further, in the door lock device 1, when the inside door handle IH is disposed at the locked position or the unlocked position, the release indicated by a two-dotted line in FIG. 6 centering on the axis of the inside door handle shaft IHX. The operation of rotating the inside door handle operation portion IHa counterclockwise so as to exceed the position is referred to as a door opening operation. The door lock device 1 according to the present embodiment is in contact with the latched release position of the inside door handle IH when the third position and the fourth position of the main inside door handle lever 80 described above coincide with each other. It is configured to match the position.

  Even when the link lever 60 moves upward as shown in FIG. 21, the link lever connection pin 53 a of the lock lever 50 only moves inside the connection hole 62 a of the link lever 60 in accordance with the movement. Thus, the lock lever 50 does not swing around the axis 50x with the movement of the link lever 60 described above.

  Further, the main inside door handle lever 80 swings as shown in FIG. 21, and by this swinging, the sub inside door handle lever 90 swings clockwise in FIG. 21 about the axis 80x. Even in this case, the lock lever connecting pin 93a of the sub inside door handle lever 90 only moves inside the lever insertion groove 54H of the lock lever 50 along with the swinging of the sub inside door handle lever 90. With the movement, the lock lever 50 does not swing around the shaft center 50x.

  Thereafter, when the person who gets into the vehicle removes the opening operation of the inside door handle IH, the biasing force of the unlock position setting spring 80s causes the main inside door handle lever 80 to move to the second position as shown in FIG. The inside door handle IH returns to the unlocked position, the connect lever 100 returns to the initial position, and the outside door handle lever 40 is initially moved by the biasing force of the outside door handle lever biasing spring. It will return to the position.

  By the way, when the door D is opened with respect to the vehicle body B and the door lock device 1 is in the initial state shown in FIG. 2, when the manual operation portion 144a of the child lever 140 is rotated counterclockwise and the manual operation portion 144a is moved upward, the child pin 150 occupied at the interlocking position shown in FIG. The inside of the first hole 83a of the pin engagement hole 83H shown is moved in the radially inward direction of the shaft center 80x and is arranged at the non-interlocking position, and the child lock mechanism is switched to the non-transmission state.

  In this state, when the inside door handle IH is arranged at the full stroke position by the door opening operation, the main inside door handle lever 80 is moved from the second position shown in FIG. 22 to the third position in accordance with the door opening operation. After that, since the child pin 150 is occupied at the non-interlocking position, the child pin 150 is moved to the first position when the main inside door handle lever 80 is swung. The connect lever 100 does not rotate with the swing of the main inside door handle lever 80 only by moving inside the two holes 83b. As a result, the outside door handle lever 40, the open lever 70, and the ratchet lever 38 do not swing, and the latch mechanism L maintains the latched state, and the door D can be opened and moved relative to the vehicle body B. Can not.

  In addition, since the child pin 150 is in the non-interlocking position, the sub-inside door handle lever 90 swings together with the swing of the main inside door handle lever 80 when the inside door handle IH is opened. There is nothing. As a result, the lock lever 50, the link lever 60, and the open lever 70 do not swing.

  Thereafter, with the door D opened with respect to the vehicle body B, the operator rotates the manual operation unit 144a clockwise in FIG. 22 around the axis 140x, and moves the manual operation unit 144a downward. Then, the child pin 150 that has been occupied at the non-interlocking position shown in FIG. 22 moves in the first hole 83a shown in FIG. The lock mechanism is switched to the transmission state.

  By the way, as described above, when the door D is in the initial state and the door lock device 1 is in the initial state shown in FIG. 2, the person riding in the vehicle focuses on the axis of the inside door handle shaft IHX. 6, the inside door handle operation portion IHa is rotated clockwise (that is, the inside door handle operation portion IHa is rotated so that the tip of the inside door handle operation portion IHa is close to the wall on the back side of the recess 15). 6, when the inside door handle IH is locked so that the inside door handle operating portion IHa is disposed at the lock position indicated by the solid line, the locking operation by the person is performed via the inside door handle linking member 14. As shown in FIG. 23, the main inside door handle lever 80 is transmitted to the main inside door handle lever 80. 0, swings counterclockwise around the axis 80x, and thus disposed in a first position.

  The swing of the main inside door handle lever 80 described above is transmitted to the sub inside door handle lever 90 by the child pin 150, and along with the swing of the main inside door handle lever 80, the sub inside door handle lever 90 is also centered on the axis 80x. Rotate counterclockwise.

  At this time, the lock lever connecting pin 93a of the sub inside door handle lever 90 rotates counterclockwise while coming into contact with the first contact wall 54a of the lock lever 50, so that the sub inside door handle lever 90 rotates counterclockwise. With this rotation, the lock lever 50 rotates clockwise around the axis 50x and is disposed at the lock swing position.

  Moreover, as described above, when the lock lever 50 rotates toward the lock swing position, the link lever 60 rotates counterclockwise about the shaft center 60x and is disposed at the link lever lock swing position. . Further, since the link lever 60 rotates as described above while the abutting wall 63 abuts the link abutting portion 74, the open lever 70 in FIG. It will rotate counterclockwise. When the open lever 70 is rotated in this manner, the ratchet driving portion 73 is disposed at a non-release position where it is disengaged from the portion facing the lower end surface of the contact portion 39 of the ratchet lever 38 and the lock mechanism is in the locked state. Switch.

  As shown in FIG. 23, when the lock mechanism is in a locked state and is outside the vehicle, and a person who gets on the vehicle operates to open the outside door handle OH, the axis of the outside door handle lever shaft 40X The outside door handle lever 40 rotates counterclockwise in FIG. 8A around the center 40x, and the outside operation end 43 moves upward in FIG. As the outside operation end 43 moves, the link lever 60 and the open lever 70 move upward, but the ratchet drive unit 73 of the open lever 70 does not contact the contact portion 39 of the ratchet lever 38. . As a result, since the latched state of the latch mechanism L cannot be released, the door D cannot be opened and moved with respect to the vehicle body B.

  Further, as shown in FIG. 23, when the locking mechanism is in a locked state, a person riding in the vehicle releases the latched state indicated by a two-dot chain line in FIG. 6 around the axis of the inside door handle shaft IHX. When the door opening operation is performed to rotate the inside door handle operating portion IHa counterclockwise beyond the position to the full stroke position, the main inside door handle lever 80 is resisted against the urging force of the unlock position setting spring 80s. However, as shown in FIG. 25, the inside door handle linking portion 82 is moved to the maximum swing position as shown in FIG. Will be placed.

  When the main inside door handle lever 80 swings as described above, the child pin 150 also moves in the clockwise direction in FIG. 23 about the shaft center 80x while contacting the connect pressure receiving portion 102 of the connect lever 100.

  The movement of the child pin 150 causes the connect lever 100 to rotate counterclockwise in FIG. 23 about the axis 100x of the connect lever shaft 100X.

  In addition, since the connect lever 100 rotates in the counterclockwise direction in FIG. 23 while its own connect pressing portion 103 is in contact with the outside pressure receiving portion 44, the outside operation end corresponds to the rotation of the connect lever 100. The portion 43 moves upward in FIG. As the outside operation end 43 moves, the open lever 70 moves so that the link lever 60 moves upward and the ratchet drive unit 73 is disposed in the lateral region of the ratchet lever 38 as shown in FIG. It will move upward.

  On the other hand, when the main inside door handle lever 80 swings from the state shown in FIG. 23 as shown in FIG. 24, the lock lever connecting pin 93a simply moves inside the lever insertion groove 54H at the initial stage of the swing. The lock lever connecting pin 93a does not come into contact with the second contact wall 54b.

  Thereafter, as the main inside door handle lever 80 swings about the shaft center 80x, the distance between the lock lever connecting pin 93a and the second contact wall 54b gradually approaches. Eventually, as shown in FIG. 24, the lock lever connecting pin 93a comes into contact with the second contact wall 54b of the lever insertion groove 54H.

  Thereafter, when the main inside door handle lever 80 further swings around the shaft center 80x in the state in which the lock lever connecting pin 93a and the second contact wall 54b are in contact with each other, the lock swing is performed. The lock lever 50 at the position swings counterclockwise about the axis 50x. When the lock lever 50 exceeds the lock intermediate position, as shown in FIG. 25, the lock lever 50 is arranged at the unlocked swing position by the biasing force of the overcenter biasing spring 50s.

  At this time, the lock lever 50 rotates while the link lever connecting pin 53a contacts the inner peripheral surface of the connecting hole 62a, so that the link lever 60 rotates clockwise around the axis 60x according to the rotation of the lock lever 50. Then, the link lever 60 is disposed at the link lever unlock swing position.

  Further, when the link lever 60 rotates as described above, the state where the link contact portion 74 and the contact wall 63 are in contact with each other by the urging force of the panic spring 70s is maintained at the initial stage of rotation. With the rotation of the link lever 60, the open lever 70 rotates clockwise about the axis 70x.

  Thereafter, as shown in FIG. 25, when the open lever main body 76 comes into contact with the side portion of the ratchet lever 38, the link contact portion 74 and the contact wall 63 against the urging force of the panic spring 70s. Separate.

  Thereafter, when the opening operation force is released from the inside door handle IH, the main inside door handle lever 80 is disposed at the second position by the biasing force of the unlock position setting spring 80s as shown in FIG. It becomes.

  Further, the swing of the main inside door handle lever 80 described above is transmitted to the sub inside door handle lever 90 by the child pin 150, and together with the swing of the main inside door handle lever 80, the sub inside door handle lever 90 also has the axis 80x. The lock lever connecting pin 93a contacts the second contact wall 54b.

  Further, the biasing force of the outside door handle lever biasing spring causes the outside door handle lever 40 to return to the initial position, and the link lever 60 and the open lever 70 return to the state of moving downward as shown in FIG. Become.

  At this time, in the open lever 70, the link abutment portion 74 is abutted against the abutment wall 63 of the link lever 60 by the urging force of the panic spring 70s, and the lock mechanism is brought into the unlocked state. It will be switched.

  After this, the person who has boarded the vehicle again, the center of the inside door handle shaft IHX, the inside door to the full stroke position, for example, beyond the latched release position indicated by the two-dot chain line in FIG. When the handle operating portion IHa is rotated counterclockwise and the door opening operation is performed, the main inside door handle lever 80 moves against the urging force of the unlock position setting spring 80s in FIG. As shown in FIG. 21, the inside door handle linkage portion 82 is disposed at the third position and then disposed at the maximum swing position.

  When the main inside door handle lever 80 swings as described above, the child pin 150 moves clockwise in FIG. 21 around the shaft center 80x while abutting against the connect pressure receiving portion 102 of the connect lever 100.

  The movement of the child pin 150 causes the connect lever 100 to rotate counterclockwise in FIG. 21 about the axis 100x of the connect lever shaft 100X.

  In addition, since the connect lever 100 rotates in the counterclockwise direction in FIG. 21 while its own connect pressing portion 103 is in contact with the outside pressure receiving portion 44, the outside operation end corresponds to the rotation of the connect lever 100. The part 43 will move upward in FIG. As the outside operation end 43 moves, the link lever 60 and the open lever 70 move upward (in the release direction) as shown in FIG. 21, and the ratchet drive unit 73 of the open lever 70 moves to the ratchet lever 38. This is in contact with the contact portion 39, and is moved upward in FIG. As a result, even when the latch mechanism L is in the latched state, the latched state can be released, so that the door D can be opened and moved relative to the vehicle body B.

  Thereafter, when the person who gets into the vehicle removes the opening operation of the inside door handle IH, the biasing force of the unlock position setting spring 80s causes the main inside door handle lever 80 to move to the second position as shown in FIG. The inside door handle IH is placed in the unlocked position by the biasing force of the overcenter biasing spring 50s, the connect lever 100 returns to the initial position, and the biasing force of the outside door handle lever biasing spring is As a result, the outside door handle lever 40 returns to the initial position.

  According to the door lock device 1 described above, the inside door handle IH is disposed at the lock position when the lock mechanism is in the locked state, and the inside door handle IH is disposed at the unlock position when the lock mechanism is in the unlocked state. Therefore, the state of the lock mechanism can be understood by looking at the inside door handle IH. Therefore, there is no need to provide a part for displaying the state of the lock mechanism such as a sill knob. Therefore, since it is not necessary to provide a linking member that links the sill knob or the like and the door lock device 1, an increase in the number of parts can be prevented. In addition, when the main inside door handle lever 80 is moved to the third position by the operation of the inside door handle IH from the state where the main inside door handle lever 80 is moved to the first position by the overcenter biasing spring 50s, While the open lever 70 is disposed at the release position via the lock mechanism, the main inside door is operated by operating the inside door handle IH from the state in which the main inside door handle lever 80 is moved to the second position by the overcenter biasing spring 50s. When the handle lever 80 is moved to the third position, the open lever 70 is moved in the release direction, so that the state of the lock mechanism can be switched by operating the inside door handle IH, improving operability. be able to. Further, even when the main inside door handle lever 80 is moved from the first position to the third position by the operation of the inside door handle IH with the open lever 70 disposed at the non-release position, the latch mechanism L is in the latched state. Since it cannot be canceled, safety can be improved.

  Further, according to the door lock device 1, the inside door handle biasing spring IHs that biases the inside door handle IH toward the lock position set outside the vehicle between the inside door handle IH and the door D. When the open lever 70 is moved from the unlocked position to the non-released position by driving the lock actuator 110, the door D is moved when the inside door handle IH is moved from the unlocked position toward the locked position. And the inside door handle IH, the inside door handle biasing spring IHs can prevent the drive force of the lock actuator 110 from being directly applied to the foreign material, and the inside door handle IH and the foreign material are damaged. The situation can be prevented.

  In the above-described embodiment, the door lock device 1 provided on the door D of the front hinge disposed on the right rear seat of the vehicle has been described. However, the present invention is not limited to this, and may be applied to a door disposed on the left side of the rear seat of the vehicle, or may be applied to a door disposed on the front seat side of the vehicle. In addition, when applying the said door lock apparatus 1 to the front seat side of a vehicle, it is not necessary to provide a child lock mechanism. Further, when the child lock mechanism is not provided, the main inside door handle lever 80 and the sub inside door handle lever 90 do not need to constitute the inside door handle lever 190, and the function of the main inside door handle lever 80, An inside door handle lever having the function of the sub inside door handle lever 90 may be formed.

  In the door lock device 1 described above, the third position and the fourth position of the main inside door handle lever 80 match, and the release position of the inside door handle IH in the latched state matches the contact position. Explained with things. However, the present invention is not limited thereto, and the third position and the fourth position of the main inside door handle lever 80 are different, and the release position of the latched state of the inside door handle IH and the contact position are different.
