When the outside handle 5 is opened and closed (in the same direction in the embodiment) or the inside handle 6 is closed, the linkage lever 16 rotates in the release direction and is fully opened via the cable 33. The operating force is transmitted to the device 3. In response to this, the fully opening latch device 3 performs the latch releasing operation and permits the door closing operation of the door 1 in the fully opened position.

  The inside lever 9 is pivotally supported on the other side surface of the base plate 7 so as to be able to rotate integrally with the pivot 18, and based on the opening operation of the inside handle 6 fixed to the inner side end of the pivot 18, It rotates against the urging force of 30 from the standby position (FIGS. 3 to 6, 9 and 10) in the release direction (clockwise in FIGS. 3 and 5 to 10).

  The release lever 10 is pivotally supported on one side surface of the base plate 7 by a pivot 18 so as to be able to rotate independently of the outside lever 8 and the inside lever 9. A substantially fan-shaped opening 26 is formed in the entire region of the hole 19 so as to overlap. Below the opening 26, the release lever 10 is provided on the first lock lever 13, which will be described later, when the release lever 10 rotates in the release direction (clockwise in FIGS. 3 and 5 to 10) against the urging force of the spring 29. An overriding portion 101 that can abut against the abutment portion 131 is provided. Also, the downward arm portion 102 is connected to the ends of cables 27 and 28 for transmitting a door opening operation force to the front and rear fully closing door latch devices 2A and 2B.

  The release lever 10 stands by based on the opening operation of the outside handle 5 (when the lock member is in the unlocked state described later) or the inside handle 6 (when the child lock lever 15 is in the unlocked position described later). By rotating in the release direction (clockwise in FIGS. 3 and 5 to 10) against the biasing force of the spring 29 from the position (see FIGS. 3 to 5 and FIGS. 9 to 10), the cables 27 and 28 are connected. Thus, the operating force is transmitted to the front and rear fully closing door latch devices 2A and 2B. Thereby, the front and rear fully-closed door latch devices 2A and 2B permit the door opening operation of the door 1 that is latched and held in the fully-closed position.

  Note that the opening 26 of the release lever 10 overlaps with the engagement hole 19a of the control hole 19 in the vehicle outside direction regardless of the position of the outside lever 8 and the release lever 10, and the engagement / disengagement pin It is provided in a size that allows 36 movements.

  The first and second lock levers 13 and 14 are rotatably supported on one side surface of the base plate 7 by a pivot 35 that faces inward and outward of the vehicle, and the urging force of the spring 37 acting between the lock levers 13 and 14. And can be moved to an unlocked position (FIGS. 3, 4, 6 and 8) and a locked position (FIGS. 5, 9, 10). The spring 37 is wound around the pivot 35, and one end is locked to the first lock lever 13 and the other end is locked to the second lock lever 14. The biasing force of the spring 37 unlocks the second lock lever 13. And the biasing force of the turnover spring 38 that elastically holds the locking position with a predetermined holding force. Accordingly, the second lock lever 14 is normally held in a state in which the rear upper edge is in contact with the first lever 13 by the biasing force of the spring 37 against the first lock lever 13.

  The rear end of the first lock lever 13 is supported by the support shaft 112 on the housing 113 of the locking actuator 11 and can be rotated by a predetermined range by the power of a motor (not shown) housed in the housing 113. And is moved to the unlocking position and the locking position in accordance with the operation of the output lever 111, and a contact portion 131 facing the override action portion 101 of the release lever 10 is provided at the front end portion thereof. . The contact portion 131 contacts the override operation portion 101 when the release lever 10 rotates in the release direction when the first lock lever 13 is in the locked position. Accordingly, the first lock lever 13 performs a so-called override operation in which the first lock lever 13 is moved from the locked position to the unlocked position as the release lever 10 rotates in the release direction.

  The second lock lever 14 has an arc-shaped elongated hole 141 centered on the pivot 18 at the upper portion thereof, and this elongated hole 141 forms an engaging / disengaging member that is slidably engaged with the control hole 19. The engagement / disengagement pin 36 is slidably engaged.

  When the second lock lever 14 is in the unlocked position, the engagement / disengagement pin 36 is positioned (unlocked position) in the engagement hole 19a in the control hole 19 of the outside lever 8 and is also in the locked position. Then, it is positioned (locking position) in the idle swing hole 19b.

  When the engagement / disengagement pin 36 is positioned in the engagement hole 191a, when the outside lever 8 is released and rotated, the engagement / disengagement pin 36 is driven to open the opening edge 26a in the opening 26 of the release lever 10. The release lever 10 rotates together with the outside lever 8 in the release direction. Further, when the engagement / disengagement pin 36 is positioned in the idle swing hole 19b, the engagement / disengagement pin 36 is not engaged with the engagement / disengagement pin 36 even if the outside lever 8 is released and rotated. Stops at that position, and the release lever 10 does not rotate in the release direction. In other words, when the first and second lock levers 13 and 14 are in the locked position, that is, when the lock member is in the locked state, the outside handle 5 is opened to open the door 1 from the outside of the vehicle. Even if the operation is performed, the outside lever 8 is swung and the front and rear fully-closed door latch devices 2A and 2B cannot be released and the door 1 cannot be opened.

  When the lock actuator 11 is unlocked while the first and second lock levers 13 and 14 are in the locked position, that is, the lock member is in the locked state and the outside lever 8 is rotating in the release direction. As shown in FIG. 9, the engagement / disengagement pin 36 engages in the radial direction with respect to the idle swing hole 19b, and a state in which it cannot be displaced to the engagement hole 19a occurs. That is, a panic state that cannot be unlocked despite the unlocking operation of the locking actuator 11 occurs. However, in the embodiment according to the present invention, even if a panic condition occurs, only the first lock lever 13 is brought into the unlocked position against the urging force of the spring 37 by the driving force of the locking actuator 11. Can be moved. Therefore, when the opening operation of the outside handle 5 is temporarily stopped and the outside lever 8 returns to the standby position, the engagement / disengagement pin 36 and the idle swing hole portion 19a are disengaged. The 2 lock lever 14 can be displaced into the engagement hole 19a by the urging force of the spring 37 to be in an unlocked state.

  When the inside lever 9 is released by the opening operation of the inside handle 6, even if both the lock levers 13 and 14 are in the locked position and the engagement / disengagement pin 36 is located in the idle swing hole 19b, Regardless, the door 1 can be opened by the override operation, and at the same time, both the lock levers 13 and 14 can be moved to the unlocked position. That is, when the inside handle 6 is operated to open the door when the engagement / disengagement pin 36 is positioned in the idle swing hole portion 19b and the first and second lock levers 13 and 14 are in the locked position, When the release lever 10 is rotated in the release direction via the inside lever 9, the front and rear fully-closed door latch devices 2 </ b> A and 2 </ b> B are connected via the cables 27 and 28. While transmitting the operating force, the override action part 101 of the release lever 10 comes into contact with the contact part 131 of the first lock lever 13. As a result, the front and rear fully-closed door latch devices 2A and 2B are operated to release the latch, and the first and second lock levers 13 and 14 are rotated from the locked position to the unlocked position. It moves from the idling hole 19b to the engagement hole 19a. In this case, as apparent from FIG. 7, the outside lever 8 does not rotate in the release direction while remaining at the standby position.

  The child lock lever 15 is pivotally supported on the other side of the base plate 7 by a pivot 40, and is exposed to the front end surface of the door 1 at the front thereof, and an operation portion 151 that can be operated only when the door 1 is opened. The unlocking position (see FIGS. 2 to 10) that allows the release rotation of the inside lever 9 to be transmitted to the release lever 10 and the locking that cannot be transmitted by operating the operation portion 151 in the vertical direction. It is possible to move to a position (indicated by a two-dot chain line in FIG. 5).

  In the elongated hole 153 provided in the upward arm portion 152 of the child lock lever 15, the engagement / disengagement pin 41 slidably engaged in the elongated hole 104 provided in the forward arm portion 103 of the release lever 10 slides. It is movably engaged. When the child lock lever 15 is in the unlocked position, the engagement / disengagement pin 41 is located within the movement locus of the forward arm portion 91 of the inside lever 9 so that the release operation of the inside lever 9 can be transmitted to the release lever 10. Similarly, when in the locked position, it is located outside the movement trajectory of the forward arm portion 91 so that the release operation of the inside lever 9 cannot be transmitted to the release lever 10.

  The emergency operation lever 17 is pivotally supported on the other side of the base plate 7 by a pivot 42 and is normally held in a standby position (see FIGS. 3 to 9) by a spring 44. An operation portion 171 that is exposed on the front end surface of the door 1 and that can be operated only when the door 1 is opened is provided, and the lower portion is provided with a connecting link 43 that faces the front-rear direction capable of transmitting the operation force of the emergency operation lever 17. Via the output lever 11 of the locking actuator 11.

  The connection link 43 has a front end portion rotatably connected to the emergency operation lever 17 by a connection shaft 45, and a rear end portion connected to the connection shaft 111a of the output lever 111 through a long hole 431 in the front-rear direction. . The connecting shaft 111a of the output lever 111 is engaged with the long hole 431 so as to be slidable in the front-rear direction. When the output lever 111 is in the unlocked position (see FIGS. 3, 4, and 6 to 9), It is located at the rear end of 431, and is also located at the front end of the long hole 431 when in the locking position (see FIGS. 5 and 10). Thus, the emergency operation lever 17 is always held at the standby position without being interlocked with the movement of the output lever 11.

  When the lock actuator 11 cannot be driven due to an electrical failure such as battery exhaustion, the operation unit 171 exposed to the front end surface of the door 1 is resisted against the biasing force of the spring 44 with the door 1 opened. Then, by manually operating in the locking direction (upward), the first lock levers 13 and 14 can be moved to the locking position via the connection link 43 and the output lever 111.

Next, the operation of this embodiment according to the present invention will be described.
(As shown in FIGS. 3 and 4, when the relay operating device 4 is in the unlocked state and the child lock lever 15 is in the unlocked position)
When the outside handle 5 is opened from the outside of the vehicle, the outside lever 8 is released as shown in FIG. Following this, the engagement / disengagement pin 36 engages with the engagement hole portion 19a in the control hole 19 of the outside lever 8 and the opening edge portion 26a in the opening portion 26 of the release lever 10, and together with the outside lever 8 Moving. Along with this, the release lever 10 is released together with the outside lever 8 via the engagement / disengagement pin 36, and the opening operation is performed on the front and rear fully-closed door latch devices 2A, 2B via the cables 27, 28. Transmit power. Thereby, the door 1 can be opened from the outside of the vehicle.

  When the inside handle 6 is operated to open the door from the inside of the vehicle, as shown in FIG. 8, the engagement / disengagement pin 41 is located in the movement locus of the forward arm 91 of the inside lever 9, so that the release lever 10 is Following the release rotation of the inside lever 9 and rotating in the release direction, the opening operation force is transmitted to the front and rear fully-closed door latch devices 2A and 2B via the cables 27 and 28. Thereby, the door 1 can be opened from the inside of a vehicle. At this time, since the opening 26 of the release lever 10 does not engage with the engagement / disengagement pin 36, the outside lever 8 is held at the standby position.

(As shown in FIG. 5, when the relay operating device 4 is in the locked state and the child lock lever 15 is in the unlocked position)
When the outside handle 5 is operated to open the door from outside the vehicle, even if the outside lever 8 is released and rotated, the engagement / disengagement pin 36 moves in the idle swing hole portion 19b of the control hole 19 as shown in FIG. Since the sliding is relatively performed, the release rotation of the outside lever 8 is not transmitted to the release lever 10. Therefore, the door 1 cannot be opened because the opening operation force of the outside handle 5 is not transmitted to the front and rear fully closing door latch devices 2A and 2B.

  As shown in FIG. 11, when the locking actuator 11 is driven in the unlocking direction when the engagement / disengagement pin 36 moves relative to the idle swing hole 19 b and the movement to the unlocking position is restricted, 9 and FIG. 11, as the output lever 111 moves to the unlocked position, the first lock lever 13 and the second lock lever 14 are held in the locked position as the output lever 111 moves to the unlocked position. Only moves to the unlocked position against the urging force of the spring 37 and the turnover spring 38. In this case, since the holding force of the turnover spring 38 is greater than the biasing force of the spring 37, the first lock lever 13 is held in the unlocked position and does not return to the locked position.

  Thereafter, when the outside handle 5 is returned to the position before the door opening operation and the outside lever 8 is returned to the standby position, the engagement / disengagement pin 36 moves relatively in the idle swinging hole portion 19b of the control hole 19. When the position of the engagement hole 19a is reached, the second lock lever 14 is moved to the unlocking position by the urging force of the spring 37, and the engagement / disengagement pin 36 enters the engagement hole 19a. Thereby, since the relay operation device 4 is unlocked, the door 1 can be opened by rotating the release lever 10 again by opening the outside handle 5.

  When the inside handle 6 is operated to open the door from the inside of the vehicle, the inside lever 9 rotates in the release direction, and the override action portion 101 of the release lever 10 contacts the contact portion 131 of the first lock lever 13. As a result, as shown in FIG. 8, the first and second lock levers 13 and 14 move from the locked position to the unlocked position against the biasing force of the turnover spring 38, and the engagement / disengagement pin 36 is moved to the second position. It moves to the unlocking position together with the lock lever 14 and enters the engagement hole 19a.

  Further, at this time, the engagement / disengagement pin 36 comes into contact with the edge of the control hole 19 and the sliding resistance is increased, and resistance is generated with respect to the engagement / disengagement pin 36 entering the engagement hole 19a. In this case, as shown in FIG. 7, first, only the first lock lever 13 to which the engagement / disengagement pin 36 is not connected is moved to the unlocked position, and then the second lock lever 14 is moved to the spring 37. The urging force moves to the unlocked position following the movement of the first lock lever 13. Thereby, in any situation, the first and second lock levers 13 and 14 can be reliably and smoothly moved to the unlocked position by the release rotation of the release lever 10, and the override operation by the inside handle 6 can be performed smoothly and smoothly. It can be done reliably.

  Even if the locking actuator 11 is driven during the opening operation of the inside handle 6, no panic occurs in this case. That is, even when the release lever 10 is released and rotated by opening the inside handle 6, the opening 26 does not interfere with the movement of the engagement / disengagement pin 36 to the unlocked position. The actuator 11 can be freely moved into the engagement hole 19a by driving the actuator 11.

(As shown in FIG. 5, when the relay operating device 4 is in the locked state and the child lock lever 15 is in the locked position)
When the inside handle 6 from the inside of the vehicle is opened, even if the inside lever 9 rotates in the release direction, the engagement / disengagement pin 41 is located outside the movement locus of the forward arm portion 91 of the inside lever 9. Therefore, the release operation of the inside lever 9 is not transmitted to the release lever 10. Therefore, in this state, even if the inside handle 6 is operated to open the door, the door 1 cannot be opened. Moreover, since the door 1 is not provided with a lock knob for manually switching the unlocked state of the intermediate operating device 4 as in the prior art, there is no possibility of being illegally switched to the unlocked state. Therefore, it is possible to reliably prevent an illegal act of opening the door 1 illegally.

(Emergency operation)
Since the door 1 in this embodiment is not provided with the lock knob and the key cylinder as described above, the operation of the lock actuator 11 becomes impossible when a failure occurs in the electric system such as battery exhaustion. The relay operating device 4 cannot be switched to the locked state by the locking actuator 11. In this case, with the door 1 opened, as shown in FIG. 10, the operation portion 171 exposed from the front end surface of the door 1 is manually operated to rotate the emergency operation lever 17 in the locking direction. As a result, the operating force of the emergency operation lever 17 is transmitted to the first and second lock levers 13 and 14 via the connection link 43 and the output lever 11, and the first and second lock levers 13 and 14 are moved from the unlocked position. It can be moved to the locked position.

  When the door 1 is closed after the first and second lock levers 13 and 14 are moved to the locking position, the front and rear fully-closed door latch devices 2A are held while the first and second lock levers 13 and 14 are held in the locking position. 2B engages with each striker and the door 1 is held in the closed position. As a result, the driver can safely leave the vehicle and prepare for repair. When ready for repair, the other door with the key cylinder can be opened with the key to repair the failure. Note that when the door 1 is in the closed position, the operation portion 171 of the emergency operation lever 17 is closed between the door 1 and the vehicle body, so that the operation portion 171 is not operated when the door 1 is closed. Practically impossible. Therefore, an unauthorized person cannot enter the vehicle while the driver is away from the vehicle.

Although the embodiment of the present invention has been described above, the following various modifications and changes can be made to the present embodiment without departing from the gist of the present invention.
(I) In the above embodiment, the opening 26 of the release lever 10 is abolished, and instead of this opening 26, as shown in FIG. 12, the release lever 10 has an engagement hole in the control hole 26 of the outside lever 8. An engagement protrusion 105 is provided that extends outward along the portion 91a and can be engaged with the engagement / disengagement pin 36 located in the engagement hole 19a. Also in this case, the engagement / disengagement pin 36 can have the same operation as that of the above embodiment because the movement in the unlocking direction is not restricted regardless of the position of the release lever 10.

(Ii) When the door 1 is opened, the operation portion 171 of the emergency operation lever 17 exposed from the front end surface of the door 1 is different from the operation portion 151 of the child lock lever 15 as shown in FIGS. A colored portion 172 that has been colored is formed. In such a case, even if the operation portions 151 and 172 of the child lock lever 15 and the emergency operation lever 17 are arranged vertically on the front end surface of the door 1, the child lock lever 15 and the emergency operation lever 17 Can be distinguished by color, and operability can be improved.

(Iii) The operation part 171 of the emergency operation lever 17 exposed from the front end surface of the door 1 is abolished. Instead, as shown in FIG. 13, an opening 1 a is provided on the front end surface of the door 1, and a push-in portion 173 facing the opening 1 a is provided on the emergency operation lever 17. With the door 1 opened, the key 46 is inserted into the opening 1a, and the pushing portion 173 is pushed inward by the key 46, whereby the emergency operation lever 17 is moved in the locking direction. In this way, the emergency operation lever 17 does not protrude from the front end surface of the door 1, so that the emergency operation lever 17 and the child lock lever 15 can be securely connected even if the child lock lever 15 is arranged in the vicinity of the emergency operation lever 17. Can be determined.
