When the gear is rotated in one direction (the other direction) 26, also the pin 26 a or 26 b optionally in the engagement recess 27a of the active lever 27 into moved (moved) in order to engage (to disengage) , whereby the active lever 27 is rotated in the clockwise (counterclockwise) direction.

The key lever 28 is made from a columnar or rod-shaped main body 28 a and a lever portion 28 is thus formed in one piece. The key lever 28 is supported together with the idle lever 29 by the first casing portion 11 a of the housing main body 11 to be rotatable. The columnar main body 28 a is formed with a groove 28 c, in which a (not shown) key cylinder extension is fitted. A back side of the lever portion 28 b with an engaging portion 28 d (see Fig. 4) is formed, which is fitted into an arcuate first engaging slot 29 of the idle lever 29. The idle lever 29 is provided b at its distal end with a second engagement slit 29 whose distal end is open. The second engagement pin 27 c of the active lever 27 is fitted into the second engagement slot 29 b. The key lever 28 , which is rotated by the actuation of the key bit (not shown) upon rotation of the key cylinder, causes the idle lever 29 to rotate either clockwise or counterclockwise in the drawing and by means of the idle lever 29 causes it to move the active lever 27 rotates either clockwise or counterclockwise in the drawing.

The second operating mechanism 30 includes the engagement lever 31 , the output lever 32 and a drive motor 33 . The engagement lever 31 , which is formed from a steel wire spring (although a different elastic wire material can be used) has a spiral base portion 31 a, a lever portion which is formed from a predetermined extension of the base portion 31 a, and a hook-shaped engagement portion 31 c, which is formed at a distal end of the lever portion 31 b. With respect to the engagement lever 31 is one end of the base portion 31 a in engagement with the engaging portion 24 of the lock operating lever 24 and an intermediate portion c of the lever portion 31b is engaged with the engagement portion 24 e of the lock operating lever 24, while the base portion 31a around the support pin 24 f is wound around, which rotatably supports the lock operating lever 24 . The engaging lever 31 is assembled with the lock operation lever 24 so as to include in the operation b to the lever portion 31, which is biased in the counterclockwise direction in the drawing. At the rear of the distal end of the lever portion 31 a of the third engaging pin 27 d of the active lever 27 at the receiving portion 24 of the lock operating lever 24 b was added.

The output lever 32 , which is rotatably connected to both the first casing section 11 a and the first cover section 12 , comprises, as shown in FIG. 4, at its opposite ends a first swivel arm section 32 a and a second swivel arm section 32 c each. The first pivot arm portion 32 a is formed at its distal end with an engagement portion 32 b, while the second pivot arm portion 32 c is formed at its distal edge with an arcuate gear portion 32 d. The electric motor 33 drives the output lever 32 to rotate it, and a worm 33 a, which is rigidly mounted on the output shaft of the motor 33 , is in meshing engagement with the gear portion 32 d of the output lever 32 . The electric motor 33 is remotely controlled by operating a double locking switch which is mounted on both the key bit and the door lining (set-up / reset operation). During the engagement lever is moved to the double locked operating position 31, as shown in FIG. 5, when the electric motor 33 is driven in one or a normal direction (ie, in the clockwise direction in the drawing) 32 holds the starting lever the engagement lever 31 in such a manner that, as shown in FIG. 7, the engaging portion 32 b of the first swing arm portion 32 a is engaged with the engaging portion 31 c 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 rotation of the output lever 32 can be established by moving the active lever to its unlocked operation in addition to reversing the electric motor 33 .

While the output lever 32 is in engagement with the engaging lever 31 (at an established position), the active lever 27 is shifted to the lock operating position, as shown in Fig. 7, and the projection portion 27e of the active lever 27 is near a top of the first Swivel arm section 32 a of the output lever 32 placed. When the active lever 27 is rotated in the clockwise direction in the drawing, thus the projecting portion 27e of the active lever 27 is engageable with the top of the first Schwenkarmabschnitts 32 a of the output lever 32 to the pivot arm 32 to urge in the downward direction which rotates the output lever 32 to rotate through an angle in the counterclockwise direction, resulting in the engagement between the output lever 32 and the engagement lever 31 being released (at a rest position).

Each of the elements of the third operating mechanism 40 is housed within a space between the second casing portion 11 b and the second lid member 13 of the case main body 11 . The second operating mechanism 40 includes an opening lever 41 and a lifting lever 42 . The opening lever 41 is rotatably supported by a support pin 43 a and a torsion spring 43 b between the second casing section 11 b and the secondary base plate 14 . A rotating end 41 a of the opening lever 41 is connected to an outer member which belongs to an outer handle on a vehicle outside, while another rotating end 41 b is connected to one end 23 c of the opening lever 23 by a fit. The opening lever 41 is rotated when the outer handle is operated in an opening direction (ie, an opening operation) to move the rotating end 41 b in the upward direction against the urging force of the torsion spring 43 b. The lifting lever 42 is rigidly mounted on a shaft section 52 b of a locking lug 52 which extends through the second cover element 13 , as will be described in detail later. The lift lever 42 is at its periphery with an engagement piece 42 a is formed, the b above an upper end of the engaging piece 23 of the opening member is placed 23rd

The pawl mechanism 50 includes a pawl 51 , a detent 52 and a pair of torsion springs 53 and 54 which urge the pawl 51 and the detent 52, respectively. The latch mechanism 50 is arranged within a space that is defined between the second cover element 13 and a base plate 15 . The pawl 51 is placed as an engaging means between the second cover member 13 and the base plate 15 so as to be rotatable on a support pin 55 which passes through the second cover member 13 and the base plate 15 . One end of the torsion spring 53 wound on the support pin 55 is engaged with the pawl 51 . The other end of the torsion spring 53 is engaged with the second cover member 13 to limit rotation of the pawl 51 and to urge the pawl 51 to return when the pawl 51 is rotated. The torsion spring 53 acts on the pawl 51 in such a way that an opening of an engagement groove 51 a of the pawl 51 essentially corresponds to an opening of an insertion groove 15 a of the base plate 15 .

The locking lug 52 comprises a block-shaped main body 52 and a shaft section 52 b, which extends perpendicularly from this. The shaft portion 52 b of the detent 52 extends through the second cover member 13 and the sub-base 14 to be supported thereby in a rotating manner and ends in an inner space of the second casing portion 11 b of the case main body 11 . The torsion spring 54 is wound on a portion of the shaft portion 52 b of the detent 52 , which is located between the second cover element 13 and the secondary base plate 14 . A distal end of the shaft portion 52 b is fixed with the lever 52 to rotate integrally. The torsion spring 54 , the opposite ends of which engage the detent 52 and the sub-base 14, respectively, to limit rotation of the detent 52 and return the detent 52 when the detent 52 is rotated. The main portion 52 a of the detent 52 is brought into engagement with an outer surface of the pawl 51 .

When a bolt 56 , which is provided on a vehicle body side, enters relatively through the fitting groove 15 a of the base plate 15 , the pawl 51 receives the bolt 56 against the urging force of the torsion spring 53 . Incidentally, the detent 52 is slidably engaged with an outer surface of the pawl 51 to be engaged with the engaging portion 51 b. Thus, the pawl 51 is in a rotational state, the bolt 56 being received therein and being held by the latch 52 , whereby an engagement with the bolt 56 is brought about and the resulting engaged state is maintained. In such a condition, the door is in a closed condition.

In the engaged state, the pawl is continuously pushed 51 by the torsion spring 53 for the reversal when the locking lug 52 is rotated to extend from the engagement portion 51 b to remove due to a rotation of the lift lever 42, the pawl will be returned by the torsion spring 53 51 and the opening of the engagement groove 51 a is rotated to match the opening of the fitting groove 15 a of the base plate 15 . In the resulting state, the bolt 56 can move away from the engagement groove 51 a of the pawl 51 and the fitting groove 15 a of the base plate 15 . In this state, the door is ready to be opened. The detent 52 acts to selectively establish engagement between the pawl 51 and the bolt 56 and a non-engaged state between the pawl 51 and the bolt 56 . If the locking lug 52 is rotated against the urging force of the torsion spring 54 , the locking lug 52 is released from the engagement section 51 b of the pawl 51 in order to release the engagement between the pawl 51 and the bolt 56 .

The present door lock device performs the following operation, as will be described in detail later: An operation that establishes a locked state in which the engagement between the pawl 51 and the bolt 56 cannot be released. An operation that establishes an unlocked state in which the engagement between the pawl 51 and the bolt 56 can be released; 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 cannot be released to the unlocked state; and an actuator that establishes releasing the double-locked state.

A first actuation is opening the door by actuating the inner handle on the inside of the vehicle when the door lock device is in the unlocked state, as shown in FIG. 4. When the inner handle is operated to open the door, the resultant force is transmitted to the third inner lever 61 by means of the inner cable 62 , which leads to the third inner lever 61 in the clockwise direction in the drawing, whereby the first inner lever 51 is rotated in the clockwise direction in the drawing. While the first inner lever 21 is rotated in the clockwise direction in the drawing ( FIG. 4), the distal end 21 d of the inner lever 21 is engaged with the lower side of the engaging piece 23 b of the opening member 23 . Then, the opening member 23 is moved in the upward direction, with the result that the upper end of the engaging piece 23 b of the opening member is brought into engagement 23 is rotated with the engagement piece 42 a of the lifting lever 42, whereby the lift lever 42nd The resulting lifting lever 42 causes the detent 52 to rotate to release it from the engaging portion 51 b of the pawl 51 .

Thus, the pawl 51 , which is free from the limitation by the detent 52 , is returned by the urging force of the torsion spring 53 . When the force acting to open the door moves the pawl 51 from the bolt 56 , the pawl 51 is released from the engagement between the pawl 51 and the bolt 56 while the pawl 51 rotates. That is, the opening operation of the inner handle releases the engagement between the pawl 51 and the bolt 56 to allow the door to be opened.

A second operation is to open the door by operating the outer handle on the outside of the vehicle when the door lock device is in the unlocked state, as shown in FIG. 4. If the outer handle is operated to open the door, the opening lever 41 is rotated against the urging force of the torsion spring 43 b. Then, the opening member 23 is moved in the upward direction, with the result that the upper end of the engaging piece 23 b of the opening member is brought into engagement 23 is rotated with the engagement piece 42 a of the lifting lever 42, whereby the lift lever 42nd The resulting lift lever 42 causes the detent 52 to rotate for the disengagement of the same from the engaging portion 51b of the pawl 51st

Thus, the pawl 51 , which is free from the limitation by the detent 52 , is returned by the urging force of the torsion spring 53 . When the force acting to open the door moves the pawl 51 from the bolt 56 , the engagement of the pawl 51 between the pawl 51 and the bolt 56 is released as the pawl 51 rotates. That is, the opening operation of the outer handle releases the engagement between the pawl 51 and the bolt 56 to allow the door to be opened.

A third operation is to set the locked state by operating the lock button on the inside of the vehicle, thereby inhibiting disengagement between the pawl 51 and the bolt. When the door lock device is in the unlocked state as shown in Fig. 4, the lock cable 63 is moved due to the locking operation of the lock handle, and the lock operating lever 24 is rotated in the clockwise direction in the drawing. The resultant force is transmitted to the third engagement pin 27 d, which causes the active lever 27 to rotate in the counterclockwise direction in the drawing. The resulting rotation of the active lever 27 causes the opening member 23 to rotate about a portion where the opening member 23 and the opening lever 41 are connected to each other, resulting in the opening member 23 being shifted from the unlocked operating position shown in FIG. 4 ( as an operation position in which the unlocked state is established) to the locked operation position (as an operation position in which the locked state is established). Even when the opening member 23 is operated by actuating the inner handle or the outside handle, thus misses the opening member 23 to engage the engagement piece 42 a of the lifting lever 42, whereby the lift lever 42 and the latch are not rotated 52nd

As a result, although the inner handle or the outer handle are operated to open the door, the unlocked state cannot be established, which enables the engagement between the pawl 51 and the bolt 56 to be released, thereby maintaining the locked state, which causes the door to be missed. It should be noted that when the opening member 23 is in the locked operating position (as shown in Fig. 5), the engaging portion 31 c of the engaging lever 31 is positioned above the engaging portion 32 b of the output lever 32 , thereby engaging the engaging lever 32 is made possible with the engaging portion 32 c of the output lever 32 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 shown in Fig. 4), the engaging portion 31 c of the engaging lever 31 is also disengaged from the engaging portion 32 b of the output lever 32 , thereby causing the engaging lever 31 to is placed in a standby position (a double locked operating position) at which the engaging lever 31 cannot 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 actuation is used to set up the locked state and the unlocked state of the door locking device by actuating the key bit on the outside of the vehicle to turn the key cylinder. When the key cylinder is rotated by the key bit, the lever portion 28 b of the key lever 28 is rotated to rotate the idle lever 29 . The resulting empty lever 29 , by means of the second engagement pin 27 c, causes the active lever to be rotated selectively to the unlocked actuation position ( FIG. 4) and the locked actuation position ( FIG. 5). Thus, the active lever 27 causes the opening member 23 to be selectively shifted to the unlocked position ( FIG. 4) and the locked actuation position ( FIG. 5), which means 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 released and can not be released when the outer handle is operated to open the door.

A fifth operation is for setting the locked state and the unlocked state of the door lock device when the electric motor 25 is turned on by a remote control operation, such as 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 25 is driven in one direction or the other direction, causing the gear 26 to rotate through an angle by means of the worm wheel 25 a, which leads to that one of the engaging pins 26 a or 26 b or the other is engaged with the engaging recess 27 a of the active lever 27 , whereby the active lever is selectively rotated to the unlocked operating position shown in FIG. 4 or the locked operating position 5 is shown in FIG . Thus, the active lever 27 causes the opening member 23 to be selectively shifted to the unlocked operating position shown in FIG. 4 or the locked operating position shown in FIG. 5, which means 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 released and cannot be released when the lock / unlock switch provided in the key bit is operated to open the door.

A sixth operation is for setting up a moving-in operation in which the unlocking operation of the locked state and a door opening operation can be carried out successively when the inner handle is operated to open the door while the door locking device is in the locked state ( FIG. 5), in which the engagement between the pawl 51 and the bolt 56 can not be released. While the door lock device is in the locked state, the engaging arm portion 22 b of the second inner lever 22 is placed as shown in FIG. 5 near the abutting portion 24 d of the lock operating lever 24 . In such a state, when the inner handle is operated to open the door, the second inner lever 22 is rotated together with the first inner lever 21 , urging the lock operating lever 24 to rotate together with the engaging lever 31 in the counterclockwise direction the drawing, what this results in the engagement lever 31, rotation of the active lever 27 caused in the clockwise direction in the drawing d by the third engaging pin 27, between the receiving portions 24 b of the locking operation lever 24 is held and with elastically engaged the engagement lever 31 is located.

Thus, the active lever 27 is rotated from the locked operating position shown in FIG. 5 to the unlocked operating position shown in FIG. 6, thereby bringing the door lock device into the unlocked state as shown in FIG. 6. Continued actuation of the inner handle to open the door causes the opening member 23 to be raised by means of the first inner lever 21 , whereby the lifting lever 42 is rotated, whereby the latch 52 rotates. Then the door is ready to be opened.

A seventh actuation is for bringing the door lock device into the locked state where the engagement between the pawl 51 and the bolt 56 is impossible to release to a second locked state (i.e., a double locked state) where the locked state is impossible can be solved. When the door lock device is at the locked condition, the engagement portion is 31 31 c of the engaging lever to the swinging arm 32 a of the output lever 32 faces to an engagement bring about so that 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) to rotate the output lever 32 through an angle in the clockwise direction in the drawing from the rest position shown in FIG. 5 to that shown in FIG. 7 Setup position, the lever 31 is thus brought into engagement with the output lever 32 . Thus, the resulting engagement lever 31 and the output lever 32 bring the door locking device into the double-locked state.

The double-locked state of the door locking device cannot possibly be released if an illegal or unauthorized unlocking operation is carried out on the door knob, for example, in addition to the actuation of the outer handle. To release the double-locked condition, first of all, the electric motor 33 is reversed by an angle by the remote control operation, which causes the output lever 32 to rotate by an angle in the counterclockwise direction in Fig. 7, which causes the Engagement lever 31 is rotated to the standby position at which the engagement lever 31 is ready to be engaged with the engagement portion 32 b 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 shown in FIG. 5. The locked state can be changed to the unlocked state as shown in FIG. 4 when the lock releasing 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 that is performed when the door lock button is illegally operated for external unlocking while the door lock device is in the double-locked state as shown in FIG. 7. While the door lock device is in the double locked state as shown in FIG. 7 when the lock button is operated to unlock, the lock cable 63 is moved to rotate the lock operating lever 24 in the counterclockwise direction in FIG. 8. However, the active lever 27 cannot be shifted to the unlocked operating position by rotating it due to the fact that the engaging lever 31 is engaged with the output lever 32 , which prevents the engaging lever 31 from rotating together with the lock operating lever 24 (i.e., the lock operating lever 24 performs an empty operation after the engaging portion 24 e of the lock operating lever 24 is released from the engaging lever 31 ). The door locking device thus remains in the locked state. It should be noted that when the external illegal access of the door lock knob is ended, the lock operating lever 24 is rotated clockwise by the urging force from the engaging lever 31 to return to the lock operating position as shown in FIG. 7.

A ninth operation is an operation that is performed when the inner handle is illegally operated to open the door externally while the door lock device is in the double-locked state as shown in FIG. 7. 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 device is in the double-locked state as shown in FIG. 7, the engagement arm 22 b of the second inner lever 22 is placed near the abutting portion 24 d of the lock operating lever 24 as shown in FIG. 7. In such a state, the second inner lever 22 is rotated together with the first inner lever 22 when the inner handle is operated for opening the door, is pushed so that the lock operating lever 24 whereby lock operating lever 24 is rotated in the direction to turn counterclockwise in Fig. 9. However, the active lever 27 cannot be shifted to the unlocked operating position by rotating it due to the fact that the engaging lever 31 is engaged with the output lever 32 , which prevents the rotating of the engaging lever 31 together with the locking operating lever 24 (i.e., that Lock operation lever 24 performs an empty operation after the engaging portion 24 e of the lock operation lever 24 is released from the engagement lever 31 ). The door locking device thus remains in the locked state. It should be noted that the external illegal access to the inner handle is ended with the lock operating lever 24 being rotated clockwise by the urging force from the engaging lever 31 to return to the lock operating position as shown in FIG. 7 ,

A tenth operation is an operation for transferring to the unlocked state of the door lock device immediately when the double lock state is released, in which the engagement between the pawl 51 and the bolt 56 can not be released, as shown in FIG. 7. While the door locking device is in the double-locked state, the active lever 27 is placed in its locked operating position and its swivel arm 27 e is placed near a point above the first swivel arm section 32 a of the output lever 32 . Thus, when the key bit is operated to release the lock or when remote control is performed to reverse the electric motor 25 , the door lock device can be brought into the unlocked state as shown in FIG. 5.

In the tenth operation mentioned above, which is designed to assume that a malfunction occurs in the drive system for the electric motor 33 , the key lever 28 in the key bit lock releasing operation causes the idle lever 29 to rotate the active lever 27 in the clockwise direction in FIG. 10 , In addition, upon actuation of the lock / unlock switch in the key bit (remote control operation) to reverse the electric motor 25 , the gear 26 is rotated in the counterclockwise direction in the drawing, which causes the active lever 27 to rotate in the clockwise direction in FIG. 10 causes. When the active lever 27 is rotated in the clockwise direction in the drawing, will be projection 27 placed first of all in engagement with the first swinging arm 32 a of the output lever 32, causing 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 released. Then, a further rotation of the active lever 27 causes the opening member 23 to rotate to the unlocked actuation position, which brings about an unlocked state of the door locking device. Thus, similarly to the explanation of the second actuation, the opening actuation of the outer handle enables the door to be opened when the door locking device is in this unlocked state.

The invention has thus been shown and described under Reference to the specific embodiments, it is intended however, it should be understood that the invention in no way is limited to the details of the structures shown, but that changes and modifications without deviating from that Scope of the appended claims can be performed.
