Description

  The present invention relates to a slide door fully open holding structure including stopper means for holding a slide door that opens and closes a door opening in a fully open state.

  Conventionally, when the slide door is fully opened, the latch is engaged with the striker provided on the vehicle body to fix the slide door, and the latch is engaged with the latch to fix the latch. A sliding door full open holding structure that holds the door in a fully open state is known (for example, see Patent Document 1).

In this sliding door fully open holding structure, by pulling the cable attached to the rotation lever, the rotation lever is rotated in the opposite direction to the direction of engagement with the latch to be detached from the latch. Accordingly, the latch can be detached from the striker, and the slide door can be moved in the closing direction.
JP 2002-21399 A

  By the way, if the fully opened slide door is moved in the closing direction, a force directed in the closing direction also acts on the latch provided in the sliding door.

  Thereby, the contact pressure between the latch and the striker increases, and accordingly, the contact pressure between the latch and the rotation lever also increases.

  For this reason, there has been a problem that the cable must be pulled with a large force when the rotating lever is detached from the latch in this state.

  Therefore, an object of the present invention is to provide a slide door fully open holding structure capable of preventing an increase in force for releasing the rotating lever from the latch.

  In order to solve the above problems, the present invention is a sliding door full-open holding structure including stopper means that holds the sliding door that opens and closes the door opening on the side surface of the vehicle body by moving in the vehicle longitudinal direction. The stopper means includes a striker fixed to the vehicle body, a latch rotatably supported by the slide door and capable of being engaged with and disengaged from the striker, and biasing the latch in an engagement direction with the striker. Latch urging means that engages the latch engaged with the striker and locks the latch, and lever urging means that urges the rotation lever in the direction of engagement with the latch. And a detaching means for detaching the turning lever from the latch, the latch having a swinging means for swinging with respect to the turning shaft, and the swinging means is closed to the slide door. Are the most main features that force direction swings the latch upon action.

  According to the present invention configured as described above, since the latch swings when the force in the closing direction is applied to the slide door by the swinging means, the contact area between the latch and the rotating lever is reduced, and the latch And an increase in contact pressure between the rotating lever and the rotating lever can be suppressed.

  Then, by pulling the handle 1a, the wire 16 is drawn to the rear side of the vehicle and the turning lever 14 is turned.

  Next, the operation of the sliding door fully opened holding structure of the present invention will be described.

  First, in order to make the slide door 1 fully open as shown by a solid line in FIG. 1, the handle 1a is held and the slide door 1 is moved in the vehicle direction which is the opening direction. As a result, the upper roller 3a, the lower roller 3b, and the rear roller 3c rotate while being guided by the upper rail 2a, the lower rail 2b, and the rear rail 2c, respectively, and the slide door 1 is fully opened.

  When the slide door 1 is in a non-fully opened state, the stopper means 10 is in the state shown in FIG.

  As the slide door 1 is opened, the striker 11 enters between the first and second engaging claws 21a and 21b of the latch 12, and the striker 11 comes into contact with the first engaging claw 21a. It rotates against the biasing force of the first torsion spring 13.

  When the slide door 1 is fully opened, as shown in FIG. 2, the projection claw 21 c of the latch 12 and the engagement claw 14 a of the rotation lever 14 are engaged to restrict the rotation of the latch 12 in the arrow M direction.

  Thus, the striker 11 provided on the vehicle body S and the latch 12 provided on the slide door 1 are held in an engaged state, and the fully open state of the slide door 1 is held.

  Next, when the slide door 1 is moved to the front of the vehicle in the closing direction with the handle 1a in the fully open state of the slide door 1, the slide door 1 moves slightly forward of the vehicle, and FIG. As shown, the second engaging claw 21b of the latch 12 and the striker 11 come into contact with each other.

  At this time, the latch 12 is swung by the swinging means 19, and as shown in FIG. 5A, the first and second engaging claws 21a and 21b are tilted to the lower arm 51b side, and the protruding claws 21c are the upper arms. Tilt to the 52b side.

  That is, when force is input from the striker 11 to the striker contact surface 211b of the second engagement claw 21b of the latch 12, the horizontal balance of the latch 12 is lost. As a result, the latch 12 swings, and as shown in FIG. 5A, the position of the latch 12 with respect to the rotation lever 14 is shifted, and the lever contact surface 211c of the latch 12 and the latch contact of the rotation lever 14 The contact area with the surface 141c decreases.

  Therefore, even if a force is input from the striker 11 to the striker contact surface 211b, an increase in contact pressure between the latch 12 and the rotation lever 14 can be suppressed.

  In particular, since the striker contact surface 211b of the latch 12 is displaced along the axial direction X of the rotating shaft 20 toward the upper arm 52b from the swing center P, the striker contact surface 211b faces the lower arm 51b. A force acts to make the latch 12 swing easily. Therefore, it is possible to further suppress an increase in the contact pressure between the latch 12 and the rotation lever 14.

  Further, since the lever contact surface 211c of the latch 12 is displaced along the axial direction X of the rotation shaft 20 from the swing center P toward the lower arm 51b, the lever contact surface 211c faces the upper arm 52b. A force acts to make the latch 12 swing easily. Therefore, it is possible to further suppress an increase in the contact pressure between the latch 12 and the rotation lever 14.

  Further, since the lever contact surface 211c and the latch contact surface 141a are formed in arc shapes that mesh with each other, as shown in FIG. 5A (b), the lever contact surface 211c is formed on the latch contact surface 141a. It can swing smoothly along.

  Therefore, the pivot lever 14 does not hinder the swing of the latch 12, and the contact area between the lever contact surface 211c and the latch contact surface 141a is surely reduced to suppress an increase in contact pressure. Is possible.

Here, than the distance .DELTA.l ₁ from the swing center P to reaction force input point Q, so towards the swing center P of the distance .DELTA.l ₂ to the contact force input point R is shortened, the first, The second engaging claws 21a, 21b are inclined more toward the lower arm 51b side, and the swing in the direction in which the protruding claws 21c are inclined toward the upper arm 52b side is more likely to occur.

  Therefore, the contact area between the lever contact surface 211c and the latch contact surface 141a can be sufficiently reduced, and an increase in contact pressure can be suppressed.

  When the handle 1a is pulled in this state, the wire 16 having the other end attached to the handle 1a is drawn in the direction indicated by the arrow Y as shown in FIG. 6A, and the second torsion spring 15 is attached. The rotating lever 14 rotates in the direction indicated by the arrow Z against the force, and the lever contact surface 211c and the latch contact surface 141a are separated from each other and detached from the latch 12.

  At this time, since the increase in the contact pressure between the latch 12 and the rotation lever 14 is suppressed, the pulling force of the handle 1a for releasing the rotation lever 14 does not increase, and the rotation lever 14 can be easily moved. The latch 12 can be detached.

  As described above, when the turning lever 14 is detached from the latch 12, the latch 12 becomes detachable from the striker 11, and as shown in FIG. 6B, as the slide door 1 is moved in the closing direction. The latch 12 is rotated in the direction indicated by the arrow M by the biasing force of the first torsion spring 13. Then, due to the movement of the slide door 1 and the biasing force of the first torsion spring 13, the striker 11 comes off from between the first engagement claw 21a and the second engagement claw 21b of the latch 12, and the slide door 1 is closed. Can do.

  As mentioned above, although embodiment concerning this invention has been explained in full detail with drawing, a concrete structure is not restricted to the above-mentioned embodiment. Design changes and the like within the scope not departing from the gist of the present invention are included in the present invention.

For example, as shown in FIG. 7, the swinging means 30 has a latch 33 having a linear rotation shaft 31 and a through hole 32 having an inner diameter K ₂ sufficiently larger than the outer diameter K ₁ of the rotation shaft 31. And may be configured.

  In this case, since a gap is generated between the rotation shaft 31 and the through hole 32 of the latch 33, the first torsion spring 34 supporting the latch 33 is bent, so that the latch 33 can be swung.

  As a result, the contact area between the latch 33 and the rotation lever 35 can be reduced, and an increase in contact pressure can be suppressed.

  In the above-described embodiment, the second engaging claw 21b is displaced from the swing center P toward the upper arm 52b, and the projection claw 21c is displaced from the swing center P toward the lower arm 51b. Not limited to this, they may be shifted in opposite directions.

  At this time, the first and second engaging claws 21a and 21b are inclined toward the upper arm 52b, and the protruding claws 21c are inclined toward the lower arm 51b.

  Even in this case, the contact area between the latch 12 and the rotation lever 14 decreases, and an increase in contact pressure can be suppressed.
