The key lever 28 , which is rotated upon rotation of the key cylinder by the operation of the key bit (not shown) causes a rotation of the idle lever 29 optionally in the clockwise or counterclockwise direction in the drawing and caused by the idle lever 29 that is the active lever 27 either in the clockwise or counterclockwise direction in the drawing.
  • The second operating mechanism 30 includes the engagement lever 31 , the exit lever 32 and a drive motor 33 , The engagement lever 31 which is formed of a steel wire spring (however, another elastic wire material is usable) has a spiral base portion 31a , a lever portion, which consists of a predetermined extension of the base portion 31a is formed, and a hook-shaped engagement portion 31c at the far end of the lever section 31b is trained. Regarding the engaging lever 31 there is one end of the basic section 31a in engagement with the engagement portion 24c of the lock operating lever 24 and an intermediate portion of the lever portion 31b is engaged with the engaging portion 24e of the lock operating lever 24 while the basic section 31a around the support pin 24f which is wound around the lock operating lever 24 rotatably supports. The engagement lever 31 is with the lock operating lever 24 mounted to at the actuation to the lever portion 31b to be owned, which is biased in the direction counterclockwise in the drawing. At the back of the far end of the lever section 31a is the third engagement pin 27d the active lever 27 at the receiving section 24b of the lock operating lever 24 added.
  • The exit lever 32 that is associated with both the first shroud section 11a as well as the first lid section 12 is rotatably connected, includes, as in 4 is shown at its opposite ends a first Schwenkarmabschnitt 32a and a second swing arm portion 32c each. The first swing arm section 32a is at its far end with an engaging section 32b formed during the second Schwenkarmabschnitt 32c at its far edge with an arcuate gear section 32d is trained. The electric motor 33 drives the output lever 32 to turn it, and a snail 33a attached to the output shaft of the engine 33 is rigidly mounted, is in meshing engagement with the gear portion 32d of the output lever 32 , The electric motor 33 is remote controlled by operation of a double lock switch mounted on both the key bit and the door inner panel (set up / reset operation). While the engagement lever 31 is moved to the double-locked operating position, as in 5 is shown when the electric motor 33 is driven in one or a normal direction (ie, in the clockwise direction in the drawing), the output lever stops 32 the engagement lever 31 in such a way that, as in 7 is shown, the engagement portion 32b the first Schwenkarmabschnitts 32a is engaged with the engaging portion 31c of the engaging lever 31 ,
  • The resulting engagement between the output lever 32 and the engagement lever 31 (ie a double-locked state) is released when the output lever 32 is rotated in the counterclockwise direction in the drawing. Such a rotation of the output lever 32 can be arranged by transferring the active lever into its unlocked operation in addition to the reversal of the electric motor 33 ,
  • While the output lever 32 is engaged with the engagement lever 31 (at a set position), the active lever 27 shifted to the lock operating position as in 7 is shown, and the projection portion 27e the active lever 27 becomes near a top of the first swing arm section 32a of the output lever 32 placed. When the active lever 27 is rotated in the clockwise direction in the drawing, thus becomes the projecting portion 27e the active lever 27 engaged with the top of the first swing arm section 32a of the output lever 32 to the swivel arm 32 in the direction down to urge the exit lever 32 rotates to rotate through an angle in the counterclockwise direction, which causes the engagement between the output lever 32 and the engagement lever 31 is released (at a rest position).
  • Each of the elements of the third operating mechanism 40 is within a space between the second sheath portion 11b and the second lid member 13 of the housing main body 11 accommodated. The second operating mechanism 40 includes an opening lever 41 and a lifting lever 42 , The opening lever 41 is through a support pin 43a rotatably supported and a torsion spring 43b between the second sheath portion 11b and the sub-base plate 14 , A turning end 41a of the opening lever 41 is connected to an outer member that belongs to an outer handle on a vehicle outside, while another rotary end 41b with one end 23c of the opening lever 23 connected by a fit. The opening lever 41 is rotated when the outer handle is operated in an opening direction (ie, an opening operation) to the rotation end 41b to move in the upward direction against the urging force of the torsion spring 43b , The lifting lever 42 is rigidly mounted on a shaft section 52b a catch 52 passing through the second cover element 13 extends, as will be described in detail later. The lifting lever 42 is at its periphery with an engaging piece 42a formed above an upper end of the engaging piece 23b of the opening member 23 is placed.
  • The latch mechanism 50 includes a latch 51 , a catch 52 and a pair of torsion springs 53 and 54 that the latch 51 and the catch 52 each pushing. The latch mechanism 50 is disposed within a space defined between the second lid member 13 and a base plate 15 , The handle 51 is as an engaging means between the second lid member 13 and the base plate 15 placed on a support pin 55 to be rotatable, by the second cover element 13 and the base plate 15 passes. One end of the torsion spring 53 on the support pin 55 is wound, is engaged with the pawl 51 , The other end of the torsion spring 53 is in engagement with the second cover element 13 for limiting a rotation of the pawl 51 and to urge the latch 51 to bring her back when the latch 51 is turned. The torsion spring 53 acts on the latch 51 such that an opening of an engagement groove 51a the latch 51 essentially with an opening of an insertion groove 15a the base plate 15 matches.
  • The catch 52 includes a block-shaped main body and a shaft portion 52b which extends perpendicularly from this. The shaft section 52b the latch 52 extends through the second cover element 13 and the secondary base plate 14 to thereby be supported in a rotating manner and terminate in an inner space of the second sheath portion 11b of the housing main body 11 , The torsion spring 54 is on a section of the shaft section 52b the latch 52 wound up, extending between the second cover element 13 and the sub-base plate 14 located. A far end of the shaft section 52b is with the lift lever 52 fastened to turn in one piece. The torsion spring 54 whose opposite ends coincide with the latching lug 52 and the sub-base plate 14 are each in engagement for limiting a rotation of the latch 52 and for returning the catch 52 if the latch 52 is turned. The main section 52a the latch 52 becomes engaged with an outer surface of the pawl 51 brought.
  • If a bolt 56 provided on a vehicle body side, relatively through the fitting groove 15a the base plate 15 enters, takes the latch 51 the bolt 56 against the urging force of the torsion spring 53 , Incidentally, there is the catch 52 in sliding engagement with an outer surface of the pawl 51 to be engaged with the engaging portion 51b , Thus, the pawl is located 51 in a state of rotation, the bolt 56 is absorbed in it and by the catch 52 is held, causing an engagement with the bolt 56 is brought about and the resulting engagement state is maintained. In such a state, the door is in a closed state.
  • In the engaged state, the pawl 51 continuously through the torsion spring 53 urged for the reversal when the latch 52 is rotated to move from the engaging portion 51b to remove due to a rotation of the lifting lever 42 , where the latch 51 through the torsion spring 53 is returned and the opening of the engagement groove 51a is rotated to match the opening of the fitting groove 15a the base plate 15 match. In the resulting state, the bolt can 56 from the engagement groove 51a the latch 51 and the fitting groove 15a the base plate 15 move away. Thus, in this state, the door is ready for opening. The catch 52 acts to selectively establish an engagement between the pawl 51 and the bolt 56 and a non-intrusive condition between the pawl 51 and the bolt 56 , When the latch 52 against the urging force of the torsion spring 54 is turned, the catch is 52 from the engagement section 51b the latch 51 solved the engagement between the pawl 51 and the bolt 56 to solve.
  • The present door lock apparatus performs the following operation, as described in detail later An operation that establishes a locked state in which the engagement between the pawl 51 and the bolt 56 can not be solved. An operation that establishes an unlocked state in which the engagement between the pawl 51 and the bolt 56 can be solved; an operation performed to open and close the door in the locked and unlocked state; an actuator that establishes a double locked state in which the locked state can not be released to the unlocked state; and an operation that establishes the release of the double locked state.
  • A first operation is to open the door by operating the inner handle on the inside of the vehicle when the door lock is in the unlocked state, as in FIG 4 is shown. When the inner handle is operated to open the door, the resultant force is applied to the third inner lever 61 by means of the inner cable 62 transferred to the third inner lever 61 leading in the clockwise direction in the drawing, creating the first inner lever 21 is rotated in the clockwise direction in the drawing. While the first inner lever 21 is rotated in the clockwise direction in the drawing ( 4 ), will be the far end 21d of the inner lever 21 engaged with the lower side of the engaging piece 23b of the opening member 23 , Then the opening member 23 moved in the upward direction, which causes the upper end of the engaging piece 23b of the opening member 23 is engaged with the engaging piece 42a of the lifting lever 42 , causing the lifting lever 42 is turned. The resulting lifting lever 42 causes the catch 52 to rotate to release it from the engagement portion 51b the latch 51 ,
  • Thus, the latch 51 , which becomes free from the limitation by the catch nose 52 , by the urging force of the torsion spring 53 brought back. When the force that acts to open the door, the latch 51 from the bolt 56 moves, the latch is 51 from the engagement between the pawl 51 and the bolt 56 solved while the latch 51 rotates. That is, the opening operation of the inner handle is the engagement between the pawl 51 and the bolt 56 triggers to allow the door to open.
  • A second operation is to open the door by operating the outside handle on the outside of the vehicle when the door lock is in the unlocked state, as in FIG 4 is shown. When the outer handle for opening the door is operated, the opening lever becomes 41 against the urging force of the torsion spring 43b turned. Then the opening member 23 moved in the upward direction, which causes the upper end of the engaging piece 23b of the opening member 23 is engaged with the engaging piece 42a of the lifting lever 42 , causing the lifting lever 42 is turned. The resulting lifting lever 42 causes the catch 52 for turning for releasing the engagement thereof from the engaging portion 51b the latch 51 ,
  • Thus, the latch 51 , which becomes free from the limitation by the catch nose 52 , by the urging force of the torsion spring 53 brought back. When the force that acts to open the door, the latch 51 from the bolt 56 moves, the engagement is the pawl 51 between the latch 51 and the bolt 56 solved while the latch 51 rotates. That is, the opening operation of the outer handle is the engagement between the pawl 51 and the bolt 56 triggers to allow the door to open.
  • A third operation is to set the locked state by operating the lock button on the inside of the vehicle, disengaging the engagement between the pawl 51 and the bolt is inhibited. When the door latch is in the unlocked state, as in 4 is shown, the locking cable 63 moved due to the locking operation of the locking handle, wherein the lock operating lever 24 is rotated in the clockwise direction in the drawing. The resulting force is applied to the third engagement pin 27d transmitted, which is a rotation of the active lever 27 in the counterclockwise direction in the drawing. The resulting rotation of the active lever 27 causes a rotation of the opening member 23 around a section where the opening member 23 and the opening lever 41 connected to each other, which causes the opening member 23 from the in 4 is shown shifted (as an operating position in which the unlocked state is established) to the locked operating position (as an operating position in which the locked state is established). Even if the opening member 23 is operated by pressing the inner handle or the outer handle, thus misses the opening member 23 the engagement with the engaging piece 42a of the lifting lever 42 , causing the lifting lever 42 and the catch 52 not be turned.
  • As a result, although the inner handle or the outer handle for opening the door is operated, the unlocked state can not be established, in which the disengagement of the engagement between the pawl 51 and the bolt 56 is enabled, whereby the locked state is held, resulting in that the opening of the door is missed. It should be noted that if the opening member 23 be in the locked operating position be finds (as in 5 is shown), the engaging portion 31c of the engaging lever 31 above the engaging portion 32b of the output lever 32 is positioned, whereby the engagement of the engagement lever 32 with the engaging portion 32c of the output lever 32 is possible when the output lever 32 is rotated in the clockwise direction in the drawing. When the opening member 23 is in the unlocked operating position (as in 4 is shown), there is the engaging portion 31c of the engagement lever 31 also disengaged from the engaging portion 32b of the output lever 32 , which causes the engagement lever 31 is placed at a standby position (a double-locked operating position) at which the engagement lever 31 can not be engaged with the engaging portion 32b of the output lever 32 although the output lever 32 is rotated in the clockwise direction in the drawing.
  • A fourth operation is for establishing the locked state and the unlocked state of the door lock device by operating the vehicle outside key bit to rotate the key cylinder. When the key cylinder is rotated by the key bit, the lever portion becomes 28b of the key lever 28 rotated to rotate the idle lever 29 , The resulting empty lever 29 caused by means of the second engagement pin 27c the optional turning of the active lever to the unlocked operating position ( 4 ) and the locked actuation position ( 5 ). Thus causes the active lever 27 the optional displacement of the opening member 23 to the unlocked position ( 4 ) and the locked actuation position ( 5 ), which results in that the unlocked state or the locked state can be selectively established, in which the engagement between the pawl 51 and the bolt 56 can be solved and can not be solved when the outer handle is operated to open the door.
  • A fifth operation is for establishing the locked state and the unlocked state of the door latch when the electric motor 25 is turned on by a remote control operation, such as an external operation of the lock / unlock switch provided in the key bit. When the lock / unlock switch provided in the key bit is operated, the electric motor becomes 25 driven in one direction or the other direction, causing a rotation of the gear 26 caused by an angle by means of the worm wheel 25a , which causes one of the engagement pins 26a or 26b or the other is engaged with the engagement recess 27a the active lever 27 , whereby the active lever is selectively connected to the unlocked operating position, which in 4 is shown or the locked operating position is rotated in 5 is shown. Thus causes the active lever 27 the optional displacement of the opening member 23 to the in 4 shown unlocked operating position or in 5 shown locked operating position, which results in that the unlocked state or the locked state can be optionally set, in which the engagement between the pawl 51 and the bolt 56 can be solved and can not be solved if the lock / unlock switch, which is provided in the key bit, is operated to open the door.
  • A sixth operation is to set up a movement operation in which the unlocking operation of the locked state and a door opening operation can be sequentially performed when the inner handle is operated to open the door while the door lock apparatus is in the locked state (FIG. 5 ), in which the engagement between the pawl 51 and the bolt 56 impossible to be solved. While the door lock device is in the locked state, the Eingriffsarmabschnitt 22b of the second inner lever 22 as in 5 shown placed near the attachment section 24d of the lock operating lever 24 , In such a state, when the inner handle is operated to open the door, the second inner lever becomes 22 along with the first inner lever 21 Turned, what the locking lever 24 to rotate urges together with the engagement lever 31 in the counterclockwise direction in the drawing, which causes the engagement lever 31 a rotation of the active lever 27 in the clockwise direction in the drawing caused by the third engagement pin 27d that between the recording sections 24b of the lock operating lever 24 is held and in elastic engagement with the engagement lever 31 located.
  • Thus, the active lever 27 from the locked operating position, in 5 is shown to the in 6 rotated unlocked operating position shown, whereby the door lock device is brought into the unlocked state, as in 6 is shown. Continuing the operation of the inner handle to open the door causes the opening member 23 is raised by means of the first inner lever 21 , causing the lifting lever 42 is rotated, causing the detent 52 turns. Then the door is ready for opening.
  • A seventh operation is used in the locked state bringing the door locking device, in which the engagement between the pawl 51 and the bolt 56 is impossible to release in a second locked state (that is, a double-locked state) in which the lock te state can not be solved. When the door latch is in the locked state, the engagement portion is 31c of the engagement lever 31 the Schwenkarmabschnitt 32a of the output lever 32 facing so as to cause an interference with it when the output lever 32 is rotated in the clockwise direction in the drawing. When the electric motor 33 is driven in the normal direction by operating a double lock switch of the key bit (remote control operation) for rotating the output lever 32 through an angle in the clockwise direction in the drawing of the in 5 shown rest position to the in 7 shown Einrichteposition, thus becomes the lever 31 engaged with the output lever 32 , Thus, bring the resulting engagement lever 31 and the output lever 32 the door locking device in the double locked state.
  • The double locked state of the door lock device can not possibly be solved when an illegal or unauthorized unlocking operation is performed on the door knob, for example, in addition to the operation of the outer handle. To solve the double-locked condition, first of all becomes the electric motor 33 by an angle reversed by the remote control operation, which causes the output lever 32 by an angle in the counterclockwise direction in 7 turns, which causes the engagement lever 31 is rotated to the standby position, wherein the engagement lever 31 is ready to be engaged with the engaging portion 32b of the output lever 32 (that is, the rest position of the output lever 32 ). While the engagement lever 31 is in the standby position, the door lock device is in the locked state, as in 5 is shown. The locked state may be changed to the unlocked state as in 4 is shown when the lock release operation is performed by the operation of the key bit or by the remote control drive of the electric motor 33 ,
  • An eighth operation is an operation performed when the door lock knob is unlawfully operated to unlock externally while the door lock apparatus is in the double locked state as in FIG 7 is shown. While the door latch is in the double locked state, as in FIG 7 is shown, when the lock button is actuated to unlock, the lock cable is 63 moved to the lock operating lever 24 in the counterclockwise direction in 8th to turn. The active lever 27 however, it can not be shifted to the unlocked operating position by rotating it due to the fact that the engagement lever 31 is engaged with the output lever 32 , which is a rotation of the engaging lever 31 prevents together with the locking lever 24 (that is, the lock operating lever 24 performs an empty operation after the engaging portion 24e of the lock operating lever 24 from the engagement lever 31 is solved). Thus, the door lock device remains in the locked state. It should be noted that when terminating the external illegal access of the door lock button, the lock operating lever 24 by the urging force of the engagement lever 31 is rotated in the clockwise direction to return to the lock operation position, as in FIG 7 is shown.
  • A ninth operation is an operation performed when the inner handle is unlawfully operated to externally open the door while the door lock apparatus is in the double-locked state as in FIG 7 is shown. The opening operation of the inner handle corresponds to the movement operation as described in the explanation of the sixth operation. When the door lock is in the double locked state, as in 7 is shown, the engagement arm 22b of the second inner lever 22 near the investment section 24d of the lock operating lever 24 placed as in 7 is shown. In such a condition, the second inner lever becomes 22 along with the first inner lever 22 rotated when the inner handle for opening the door is actuated, whereby the lock operating lever 24 which forces the latch actuating lever 24 is rotated to turn in the counterclockwise direction in 9 to turn. The active lever 27 however, it can not be shifted to the unlocked operating position by rotating it due to the fact that the engagement lever 31 is engaged with the output lever 32 , which is the rotation of the engaging lever 31 together with the lock operating lever 24 prevented (that is, the locking lever 24 performs an empty operation after the engaging portion 24e of the lock operating lever 24 from the engagement lever 31 is solved). Thus, the door lock device remains in the locked state. It should be noted that the external illegal access to the inner handle is terminated, with the lock operating lever 24 by the urging force of the engagement lever 31 is rotated in the clockwise direction to return to the lock operation position, as in FIG 7 is shown.
  • A tenth operation is an operation for transferring to the unlocked state of the door locking device immediately when the double locked state is released, in which the engagement between the pawl 51 and the bolt 56 impossible to be solved, as in 7 is shown. While the door latch is in the double locked state, the active lever is 27 placed at its locked operating position and its projection portion 27e is near a location above the first swing arm section 32a of the output lever 32 placed. When the key bit is operated to release the lock or when remote control is performed to reverse the electric motor 25 Thus, the door lock device can be brought into the unlocked state, as in 5 is shown.
  • In the tenth operation mentioned above, which is designed assuming the occurrence of a malfunction in the drive system for the electric motor 33 , the key lever causes 28 in the keybar lock release operation, that the idle lever 29 the active lever 27 in the clockwise direction in 10 rotates. Upon actuation of the lock / unlock switch in the key bit (remote control operation) to reverse the electric motor 25 also becomes the gear 26 rotated in the counterclockwise direction in the drawing, causing a rotation of the active lever 27 in the clockwise direction in 10 causes. When the active lever 27 is rotated in the clockwise direction in the drawing, first of all, its projection portion 27e engaged with the first swing arm section 32a of the output lever 32 , which causes a rotation of the engagement lever in the counterclockwise direction in the drawing, whereby the engagement between the engagement lever 31 and the output lever 32 is solved. Then causes a further rotation of the active lever 27 a rotation of the opening member 23 to the unlocked operating position, whereby an unlocked state of the door lock device is brought about. Thus, similar to the explanation of the second operation, the opening operation of the outside handle enables the opening of the door when the door latch is in this unlocked state.
