[0035]
Next, the operation of the vehicle lock mechanism release device according to the present embodiment will be described.
(i). When the sliding door (1) is in the fully closed position or the fully opened position, the actuator (15) is driven by operating the operation switch, and the output lever (15a) is moved in the direction of the arrow in FIG. The lever (16) is rotated in the release direction from the standby position. As a result, the second arm portion (16b) engages with the engagement pin (12f) of the outside lever (12) to rotate the outside lever (12) in the release direction. The fully open lock release lever (11) is also rotated in the release direction via one rod (20).
[0036]
As a result, the bell crank lever (16), the outside lever (12), the fully closed lock release lever (13), and the fully open lock release lever (11) are respectively released from the standby position as shown in FIG. The fully open lock mechanism (5) and the fully close lock mechanism (4) are simultaneously unlatched via the cable (19) and the cable (27).
[0037]
Therefore, when the slide door (1) is in the fully closed position, the fully closed lock mechanism (4) is unlatched by rotating the fully closed lock release lever (13) in the release direction, and then the opening and closing device ( The sliding door (1) can be opened by 2a).
[0038]
When the sliding door (1) is in the fully open position, the fully open lock mechanism (5) is unlatched by rotating the fully open lock release lever (11) in the release direction, and then opened and closed by the opening / closing device (2a). The sliding door (1) can be closed.
[0039]
(ii). When the sliding door (1) is in the fully closed position and the outside handle (9) is opened, the arm portion (9a) of the outside handle (9) moves in the direction of arrow A in FIG. The handle lever (10), the outside lever (12) and the fully-closed lock release lever (13) each turn in the release direction from the standby position. As shown in FIG. 6, each moves to the release position. At this time, since the engaging pin (12f) moves to the left in FIG. 6, that is, in a direction away from the second arm portion (16b) of the bell crank lever (16) , the outside lever (12) and the fully closed lock release Even if the lever (13) rotates in the release direction, the rotation is not transmitted to the actuator (15) via the bell crank lever (16) .
[0040]
The fully-closed lock release lever (13) moves to the release position, thereby moving the cable (27) in the direction of the arrow, unlatching the fully-closed lock mechanism (4), and opening the slide door (1). Enable operation.
[0041]
At this time, the fully open lock release lever (11) does not move from the standby position. Therefore, in the case of opening operation of the outside handle (9), only the fully-closed lock mechanism (4) is operated without operating the fully-opened lock mechanism (5), and the fully-closed lock mechanism (4 ) Can be unlatched.
[0042]
(iii). When the inside handle (28) is opened when the sliding door (1) is in the fully closed position, the inside lever (14) is rotated from the standby position to the release direction via the pivot (22). Thus, the outside lever (12) and the fully-closed lock release lever (13) are rotated from the standby position in the release direction via the step (14a) and the engagement / disengagement pin (25), respectively. Move to the release position shown in FIG.
[0043]
When the fully-closed lock release lever (13) is moved to the release position, the cable (27) is moved in the direction of the arrow to release the latch of the fully-closed lock mechanism (4) and open the slide door (1). Enable operation.
[0044]
At this time, since the upper end of the second rod (21) slides in the second elongated hole (11c), the fully open lock release lever (11) does not move from the standby position. Therefore, even when the inside handle (28) is opened, only the full-close lock mechanism (4) is operated without operating the full-open lock mechanism (5), and the full-close lock mechanism (4) is operated with a light operating force. Can be unlatched.
[0045]
(iV). When the sliding door (1) is in the fully open position, when the outside handle (9) is closed, the arm portion (9a) of the outside handle (9) moves in the direction of arrow B in FIG. Then, it comes into contact with the engaging portion (11d) of the fully open lock release lever (11). Accordingly, the fully open lock release lever (11) is rotated in the release direction from the standby position and moved to the release position shown in FIG. At this time, the upper end of the first rod (20) relatively moves upward of the first long hole (11b) as the fully open lock release lever (11) rotates in the release direction. Even if the lock release lever (11) rotates in the release direction, the rotation is not transmitted to the actuator (15) via the bell crank lever (16) .
[0046]
As a result, the cable (19) is pulled in the direction of the arrow, and the fully open lock mechanism (5) is unlatched to allow the sliding door (1) to be closed.
[0047]
At this time, the fully closed lock release lever (13) does not move from the standby position. Therefore, in the case of closing the outside handle (9), only the full-open lock mechanism (5) is operated without operating the full-close lock mechanism (4), and the full-open lock mechanism (5) is operated with a light operating force. Can be unlatched.
[0048]
(V). When the sliding door (1) is in the fully open position and the inside handle (28) is closed, the inside lever (14) is rotated counterclockwise from the standby position via the pivot (22). . Thereby, the fully open lock release lever (11) is rotated in the release direction from the standby position via the second rod (21), and moves to the release position as shown in FIG.
[0049]
As a result, the cable (19) is pulled in the direction of the arrow, and the fully open lock mechanism (5) is unlatched to allow the sliding door (1) to be closed.
[0050]
Also at this time, the fully closed lock release lever (13) does not move from the standby position. Therefore, even when the inside handle (28) is closed, only the full-open lock mechanism (5) is operated without operating the full-close lock mechanism (4), and the full-open lock mechanism (5) is operated with a light operating force. The latch can be released.
[0051]
【The invention's effect】
According to the present invention, the fully-closed lock release lever and the fully-open lock release lever are not interlocked with the movement in the release direction, but both release levers are simultaneously moved in the release direction by driving in one direction. By providing an actuator linked to each of the fully-closed lock release lever and the fully-open lock release lever , the full-open lock mechanism and the fully-closed lock mechanism can be unlatched with a single actuator, thereby reducing costs. Can do.
