Description

  The present invention relates to a slide door having a fully open lock mechanism that locks a slide door of a vehicle in a fully open position.

  The fully open lock mechanism is provided for the purpose of preventing inadvertent movement of the open slide door. When the slide door reaches the fully open state, it engages with the fully open striker fixed to the vehicle body. The sliding door is held in the fully open position. Specifically, a pawl that can rotate between a gripping position that engages with a fully open striker and holds the sliding door in a fully open position and an open position that opens the fully open striker, and a pole that rotates to the gripping position And the hook is moved to the non-engagement position (open position) with the pole by the unlocking operation (generally the operation of grasping the release lever provided on the door knob). Release the fully open lock.

On the other hand, the vehicle body is provided with a guide rail for a sliding door. The guide rail includes a parallel portion that moves the slide door in the vehicle front-rear direction, and an inclined portion that moves the slide door to a fully closed position inside the vehicle continuously from the parallel portion.

  Since the slide door is guided by such a slide rail, variation in the travel position is unavoidable due to the influence of installation. Similarly, the pole position is inevitably varied due to variations in the dimensions of components and accumulation of position intersections. For this reason, depending on the positional relationship between the slide rail and the pole, when the slide door enters the inclined portion of the guide rail, both may interfere (contact). Conventionally, in order to solve this problem, the pole is separated from the guide rail as much as possible. However, this increases the size and the number of components.

  Accordingly, an object of the present invention is to obtain a sliding door having a fully-open lock mechanism that does not interfere with a pole when the sliding door moves into an inclined portion of a guide rail.

  According to the present invention, when the slide door moves into the inclined portion of the guide rail, the roller arm provided with the roller engaging the guide rail swings according to the planar shape of the guide rail. Paying attention to the fact that the pole is moved away from the guide rail by the movement of the roller arm, the distance between the pole and the guide rail can be shortened (it does not interfere even if shortened). It is a thing.

  The present invention provides a vehicle body with a guide rail of a slide door and a fully open striker for holding the slide door in a fully open position, and the slide door is engaged with the fully open striker when the slide door reaches the fully open position. In the slide door provided with the fully open lock mechanism that holds the slide door in the fully open position, the guide rail includes a parallel part that moves the slide door in the vehicle front-rear direction, and the slide door that is continuous with the parallel part. The sliding door has a roller arm that has a roller that engages with the guide rail and swings according to the planar shape of the guide rail. The fully open lock mechanism includes a gripping position for engaging the fully open striker to hold the slide door in the fully open position, and an open position for opening the fully open striker. The slide door is provided with a pawl that can be pivoted. The slide door is opened to the open position by the swinging motion of the roller arm when the slide door moves from the parallel portion of the guide rail to the inclined portion. Further, a stopper lever that rotates in a direction away from the guide rail is provided.

  The stopper lever and the pole can be pivotally mounted on different axes, but the structure becomes simple if they are pivotally mounted on the same axis so as to be relatively rotatable. The stopper lever is formed with an engaging portion with the roller arm and a restricting portion for restricting the rotation position of the pole in the direction away from the guide rail, and the pole is attached with the rotation in the direction away from the guide rail. The stopper lever is urged to rotate in the direction approaching the guide rail, and the roller arm swings when the slide door moves from the parallel portion of the guide rail to the inclined portion. It is good to rotate in the direction away from the guide rail by movement.

  The stopper that regulates the rotation position of the stopper lever in the direction approaching the guide rail can be configured by a roller arm, but in order to avoid the contact between moving objects, It is preferable to provide it.

  According to the present invention, even if the distance between the guide rail that guides the sliding door and the pole provided in the sliding door is close, the pole does not particularly contact (interfer) with the inclined portion of the guide rail. A sliding door having a mechanism can be obtained.

  As shown in FIG. 5, a guide rail 11 for guiding the slide door 20 is provided below the rear seat entrance of the vehicle 10 (one box car). As shown in FIG. 1 and FIG. 2, the guide rail 11 includes a parallel portion (front-rear direction portion) 11 a that moves the slide door 20 in the vehicle front-rear direction, and a vehicle 10 from a front end portion of the parallel portion 11 a. And an inclined portion 11b that is inclined inward and forward. The state in which the sliding door 20 is guided (guided) by the parallel portion 11a is a state in which the sliding door 20 is positioned on the outer side away from the vehicle body and guided in the front-rear direction. The door 20 gradually moves inward to reach the fully closed position. A fully open striker 12 is fixed to the vehicle body in the vicinity of the rear end of the guide rail 11.

  On the other hand, a support frame 25 is fixed integrally with the slide door 20 in front of the lower portion of the slide door 20. A roller arm plate 26 (FIG. 1) is fixed to the support frame 25. A roller arm 27 having a roller 27a that engages with the guide rail 11 is pivotally attached to the roller arm plate 26 by a shaft 27b. Yes. The shaft 27b faces the vertical direction, and when the roller 27a reaches the inclined portion 11b from the parallel portion 11a (the inclined portion 11b to the parallel portion 11a), the roller arm 27 rotates around the shaft 27b. FIG. 3 shows how the roller arm 27 rotates. When the roller 27a moves in the parallel part 11a and when it moves in the inclined part 11b, the roller arm 27 does not rotate.

  A base plate 28 is also fixed in the support frame 25, and a fully open lock mechanism 30 that engages the fully open striker 12 when the slide door 20 reaches the fully open position is provided on the base plate 28. The fully open lock mechanism 30 includes a pole 32 and a stopper lever 33 that are pivotally mounted coaxially with a vertical shaft 31 so as to be relatively rotatable. A hook 35 is pivotally attached to a shaft 34 parallel to the shaft 31. The pole 32 has a grip groove 32a that engages with the fully open striker 12 in the fully open position. The grip position holds the slide door 20 in the fully open position around the shaft 31, and the open position opens the fully open striker 12. It is possible to rotate between the two. The pole 32 also has a lock protrusion 32b on the opposite side of the gripping groove 32a. The lock protrusion 32b can be engaged with and disengaged from the lock claw 35a of the hook 35. The pole 32 is urged by a torsion coil spring 32c (FIG. 4) to rotate away from the guide rail 11 (arrow A direction, clockwise direction in FIG. 1, striker opening direction), and the hook 35 is a torsion coil spring. 35b (FIG. 4) is urged to rotate in the same direction as the pole 32 (the direction of arrow B, the direction in which the lock claw 35a engages with the lock protrusion 32b).

  The above-described pole 32 and hook 35 perform a full open lock function as follows. When the slide door 20 reaches the vicinity of the fully open position and the fully open striker 12 relatively enters the gripping groove 32a of the pole 32, the pole 32 approaches the guide rail 11 against the force of the torsion coil spring 32c (see FIG. 1 counterclockwise). When the lock protrusion 32b reaches the engagement position of the lock claw 35a, the hook 35 instantly rotates in the engagement direction with the lock protrusion 32b, and the pole 32 is held at the grip position by the lock claw 35a. This state is a fully open lock state.

  The hook 35 is coupled to the arm 35c with a drive wire 35d for rotating the hook 35 in a direction against the rotational biasing force. The drive wire 35d is interlocked with the release lever 22 (FIG. 5) provided on the door knob 21 of the slide door 20. When the door knob 21 (release lever 22) is gripped when the slide door 20 is closed, the drive wire 35d is As a result, the hook 35 rotates in the unlocking direction to release the locking of the pole 32 by the lock claw 35a. That is, the slide door 20 is unlocked.

  In the present embodiment, the above-described stopper lever 33 is provided in addition to the above-described normal full-open position lock mechanism. The stopper lever 33 has an engaging portion 33a having a smooth curved surface located on the roller arm 27 side, and a restricting portion (stopper protrusion) 33b for restricting the rotational position of the pole 32 in the direction away from the guide rail 11. The torsion coil spring 33c (FIG. 4) is urged to rotate in the direction approaching the guide rail 11 (the direction opposite to the arrow A direction and the counterclockwise direction in FIG. 1). On the base plate 28, a stopper 28a (FIGS. 3 and 4) for restricting the rotation end of the stopper lever 33 is formed to project.

  The torsion coil spring 32c urges the pawl 32 to move away from the guide rail 11 on the stopper lever 33. Therefore, the pawl 32 rotates at a position where it abuts against the restricting portion (stopper projection) 33b. Edge is regulated. That is, the pole 32 can be relatively rotated on the stopper lever 33 in the direction approaching the guide rail 11, but always rotates together with the stopper lever 33 when the stopper lever 33 rotates. The engaging portion 33a of the stopper lever 33 does not contact the shoulder portion (roller arm guide portion) 27c of the roller arm 27 while the roller arm 27 travels on the parallel portion 11a of the guide rail 11. When 27 enters the inclined portion 11b, it is pressed by the shoulder portion 27c and rotates in a direction away from the guide rail 11.

  The slide door 20 is guided by the upper guide rail and the vehicle side guide rail in addition to the lower guide rail 11, but the support structure and other structures around the roller arm 27 are well known. There is no question of the present invention, so the explanation is omitted.

  The slide door having the above configuration operates as follows. When the slide door 20 is in the fully open position, the fully open striker 12 has entered the grip groove 32a of the pole 32, and the lock protrusion 32b engages with the lock claw 35a of the hook 35 and is held in the lock position (gripping position). Has been. In this fully open locked state, when the release lever 22 of the door knob 21 is operated to pull the drive wire 35d, the hook 35 rotates counterclockwise (opposite to the arrow B direction), and the lock claw 35a and the lock protrusion 32b. Release the engagement. Then, the pole 32 rotates to the open position by the force of the torsion coil spring 32c, and the fully open position lock is released.

  If the slide door 20 is closed as it is, the roller 27a of the roller arm 27 moves from the parallel portion 11a to the inclined portion 11b. When the roller 27a enters the inclined portion 11b, the roller arm 27 rotates about the shaft 27b, the shoulder portion 27c abuts on the engaging portion 33a of the stopper lever 33, and the stopper lever 33 moves away from the guide rail 11. Rotate in the direction. On the stopper lever 33, there is a pole 32 that is urged by a torsion coil spring 32c so as to be always in contact with the restricting portion (stopper protrusion) 33b. 32 also rotates in the same direction as the stopper lever 33, that is, in a direction away from the guide rail 11. Therefore, the pole 32 does not interfere with the guide rail 11. That is, the pole 32 can be provided at a position relatively close to the guide rail 11, and a slide door having a full-open lock mechanism with a small size and a small number of parts can be obtained.

  When the sliding door 20 is opened, contrary to the above, when the roller arm 27 enters the parallel portion 11a from the inclined portion 11b, the stopper lever 33 rotates counterclockwise according to the torsion coil spring 33c as the roller arm 27 rotates. It rotates and stops at a position where the engaging portion 33a contacts the stopper 28a. At this time, the pole 32 on the stopper lever 33 returns to a position where it can engage with the full-open striker 12, and when the slide door 20 is moved to the full-open position, the above-described full-open lock operation is performed.

It is a top view which shows 1st embodiment of the slide door provided with the full open lock mechanism by this invention. It is the same perspective view. It is a top view which shows the relationship between the roller arm and a stopper lever. It is a disassembled perspective view of the full open lock mechanism. It is a perspective view which shows the relationship between the vehicle which has a sliding door, and its guide rail.
