  Further, the slide door having the intermediate stopper mechanism of the present invention is such that the fully open holding striker is positioned closer to the door opening direction side than the body side intermediate stopper member with respect to the forward / backward direction of the slide door, and the door side intermediate stopper lever is the door side fully open lock member. It is characterized by being located on the door opening direction side.

  The fully open holding striker and the door side fully open lock member are preferably provided with their positions offset in the vertical direction of the vehicle with respect to the body side intermediate stopper member and the door side intermediate stopper lever.

  The fully open holding striker and the body side intermediate stopper member are preferably formed as an integral unit and attached to the step panel of the vehicle body.

  According to the present invention described above, in the slide door having the intermediate stopper mechanism, the arrangement of the full-open holding striker for full-opening holding and the intermediate stopper member is not easily restricted by the body shape, and the degree of freedom in design is improved. In addition, a compact sliding door structure can be obtained by bringing the fully open holding striker and the intermediate stopper member close to each other.

  Hereinafter, the present invention will be described based on illustrated embodiments. In the following description, the front-rear direction and the vertical direction mean the front-rear direction and the vertical direction of the vehicle. As shown in FIG. 1, a lower rail 12 is provided on the lower edge of the opening of an entrance 11 a that is opened on the side surface of the body 11 of the vehicle. A lower arm 32 is provided at a lower portion of the door panel 30 (FIGS. 3 to 5) of the slide door 13, and a roller (not shown) provided on the lower arm 32 is slidably fitted to the lower rail 12, so that the slide The door 13 is movable along the lower rail 12 in the longitudinal direction of the vehicle body. The slide door 13 moves forward to close the entrance / exit 11a, and moves backward to open the entrance / exit 11a. Note that the mechanism for opening and closing the slide door 13 may be either a manual operation type or an electric drive type.

  The slide door 13 is provided with a window glass 15 that can be raised and lowered. The window glass 15 can be moved up and down by a window regulator. Although the window regulator is not shown in FIG. 1, the window regulator may be a well-known one.

  A metal step panel 11b is provided on the lower side of the entrance 11a in the body 11, and the body side stopper unit 20 is fixed to the step panel 11b (FIG. 2). The body-side stopper unit 20 includes a base plate 21 whose longitudinal direction is directed in the longitudinal direction of the vehicle (the opening and closing direction of the slide door 13), and a fully open stopper bracket fixed to one end portion of the base plate 21 facing the opening direction of the slide door 13. 22 is provided.

  The fully open stopper bracket 22 has a fully open stopper portion 22a made of a hard rubber cushion material on the surface facing the front of the vehicle body. The lower arm 32 on the slide door 13 side includes a contact portion 31 (a part of which is shown in FIGS. 2 and 5) that contacts the fully open stopper portion 22a when the slide door 13 is slid in the opening direction. Further movement of the slide door 13 in the opening direction is restricted by the contact between the contact portion 31 and the fully open stopper portion 22a.

  The base plate 21 has a pair of through-holes 21aF and 21aR that are spaced apart in the longitudinal direction. The fixing plate 24F and 24R are inserted into the through-holes 21aF and 21aR and screwed into the nuts 25F and 25R to thereby obtain a plate thickness. It is fixed to the step panel 11b in a state where the plane is horizontal (FIG. 2). Of the pair of through-holes 21aF and 21aR, the rear through-hole 21aR is a long hole, so that the fixing bolt 24R can be reliably inserted and fixed even if there is an accuracy error of the parts.

  The base plate 21 has a U-shaped fully open holding striker 26 and an intermediate stopper arm 27. In a state where the base plate 21 is fixed to the step panel 11b, the fully-open holding striker 26 and the intermediate stopper arm 27 protrude in the direction of the lower surface of the body, and as shown in FIGS. 27 is the front and the fully open holding striker 26 is the rear. In other words, the fully open holding striker 26 is positioned closer to the door opening direction than the intermediate stopper arm 27 with respect to the advancing / retreating direction of the sliding door 13. The intermediate stopper arm 27 has an intermediate stopper portion 27a made of a hard rubber cushion material on the surface facing the front of the vehicle body.

  The base plate 21 has a plate-like bracket support portion 21c that is formed one step lower than the plate-like step panel attachment portion 21b in which the through holes 21aF and 21aR are formed. The fully open stopper bracket 22 has a fixed support portion 22b substantially parallel to the bracket support portion 21c, and the step panel mounting portion 21b and the fixed support portion 22b are fixed. The fully open stopper bracket 22 has a downward extending arm 22c substantially orthogonal to the fixed support portion 22b, and the fully open stopper 22a is provided on the front side of the downward extending arm 22c.

  A door-side stopper unit 40 is attached to the lower arm 32 of the slide door 13. As shown in FIGS. 3 to 6, the door-side stopper unit 40 includes a fully-open holding hook 43, an intermediate stopper lever 44, a first ratchet 45, and a second ratchet 46 between the upper plate 41 and the lower plate 42, respectively. It is pivotally supported by 43x, 44x, 45x, 46x. Each of the support shafts 43x, 44x, 45x, and 46x is formed of a cylindrical pin, and the upper plate 41 and the lower plate 42 are formed with holes through which the pins can be inserted. Each pin is inserted into a corresponding hole in the upper plate 41 and the lower plate 42, and the ends thereof are caulked to form a fixed rotation shaft. 3 to 5 show a state in which the upper plate 41 is removed in order to make it easy to see the operational relationship of the members.

  One end of the fully open holding hook 43 is pivotally supported by the support shaft 43x, and the other end projects laterally from the upper plate 41 and the lower plate 42. The tip of the projecting end is divided into a bifurcated shape and enters the striker. A groove 43a is formed. The fully-open holding hook 43 prohibits the unlock position (FIGS. 3 and 4) where the fully-open holding striker 26 can enter the striker entry groove 43a and the release of the fully-open holding striker 26 that has entered the striker entry groove 43a. It can rotate between the locked position (FIG. 5) and is urged to rotate in the unlocking direction (counterclockwise in FIGS. 3 to 5) by the urging spring 47. The fully open holding hook 43 abuts against the stopper 48 at the unlock position, and further rotation in the unlock direction is restricted. The stopper 48 is formed on the lower plate 42.

  The fully open holding hook 43 is formed with a rotation restricting concave portion 43b and an engagement preventing convex portion 43c at the outer edge near the support shaft 43x. The first ratchet 45 is supported at one end by a support shaft 45x, and has an engaging claw 45a at the other end that can engage with the rotation restricting recess 43b. The first ratchet 45 is rotationally biased by a biasing spring 49 in a direction in which the engaging claw 45a is engaged with the rotation restricting recess 43b, that is, counterclockwise in FIGS. When the fully open holding hook 43 is in the aforementioned unlock position, the outer peripheral portion of the engagement preventing projection 43c is brought into contact with the engagement claw 45a, so that the engagement between the engagement claw 45a and the rotation restricting recess 43b is blocked. (FIGS. 3 and 4). On the other hand, when the fully open holding hook 43 is rotated to the above-mentioned lock position, the first ratchet 45 is rotated by the urging force of the urging spring 49, and the rotation restricting recess 43b and the engaging claw 45a are engaged (FIG. 5). . In this engaged state, the first ratchet 45 prohibits the rotation of the fully open holding hook 43 in the unlocking direction.

  A cable 50 operated by a door handle (not shown) of the slide door 13 is connected to the first ratchet 45. The cable 50 is pulled by operating the door handle, and the first ratchet 45 is rotated clockwise in FIGS. 3 to 5 against the biasing force of the biasing spring 49. As a result, the engagement between the engagement claw 45a and the rotation restricting recess 43b is released, and the fully open holding hook 43 can be rotated in the unlocking direction. When the operation of the door handle is released, the cable 50 is relaxed, and the rotational operation force to the first ratchet 45 is eliminated.

  One end of the intermediate stopper lever 44 is pivotally supported by the support shaft 44x, and the other end projects laterally from the upper plate 41 and the lower plate 42. A stopper abutting portion 44a is formed at the projecting end. Yes. The intermediate stopper lever 44 has a protruding position (FIG. 4) where the stopper abutting portion 44a can abut against the intermediate stopper portion 27a of the intermediate stopper arm 27, and a retracted position (idle swing) where the intermediate stopper arm 27 does not abut. Position) (FIGS. 3 and 6), and is urged to rotate by a biasing spring 51 in the protruding position direction (clockwise in FIGS. 3 to 5). The intermediate stopper lever 44 abuts against the rotation restricting plate 52 at the protruding position, and further rotation of the urging spring 51 in the urging direction is restricted. The intermediate stopper lever 44 is pressed by the storage position holding member 14 (FIG. 3) provided on the body 11 side when the slide door 13 is in the fully closed position, and resists the biasing force of the biasing spring 51. Held in the storage position. The intermediate stopper lever 44 is formed with a rotation restricting concave portion 44b and an engagement preventing convex portion 44c at the outer edge near the support shaft 44x.

  The second ratchet 46 is supported at one end by a support shaft 46x, and has an engaging claw 46a at the other end that can be engaged with the rotation restricting recess 44b of the intermediate stopper lever 44. The second ratchet 46 is rotationally biased by the biasing spring 53 in the direction in which the engaging claw 46a is engaged with the rotation restricting recess 44b, that is, in the counterclockwise direction in FIGS. When the intermediate stopper lever 44 is in the protruding position, the outer peripheral portion of the engagement preventing projection 44c is brought into contact with the engagement claw 46a, and therefore the engagement between the engagement claw 46a and the rotation restricting recess 44b is blocked. (FIG. 4). On the other hand, when the intermediate stopper lever 44 is rotated to the aforementioned storage position, the second ratchet 46 is rotated by the biasing force of the biasing spring 53, and the rotation restricting recess 44b and the engaging claw 46a are engaged (FIG. 3, FIG. FIG. 5). In this engaged state, the rotation of the intermediate stopper lever 44 to the protruding position is prohibited by the second ratchet 46.

  Connected to the second ratchet 46 is a cable 54 that is pulled when the window glass 15 of the slide door 13 is opened above a certain level and relaxed when the window glass 15 is closed. When the cable 54 is pulled, the second ratchet 46 is rotated clockwise in FIGS. 3 to 5 against the urging force of the urging spring 53. As a result, the engagement between the engagement claw 46a and the rotation restricting recess 44b is released, and the intermediate stopper lever 44 can be rotated in the protruding position direction. In this embodiment, the device for opening and closing (raising and lowering) the window glass 15 may be a well-known device, and detailed description thereof is omitted.

  The urging springs 47, 49, 51 and 53 are each composed of a torsion coil spring wound around the corresponding support shafts 43x, 44x, 45x and 46x.

  The door-side stopper unit 40 is assembled in a state where the above-described elements are sandwiched between the upper plate 41 and the lower plate 42. The upper plate 41 and the lower plate 42 are formed with a pair of through holes 57F and 57R at the ends in the front-rear direction. The fixing bolts 58F and 58R are inserted into the through holes 57F and 57R to the lower arm 32, respectively. By fastening together, the upper plate 41 and the lower plate 42 are integrated (FIG. 6).

  In the state where the door-side stopper unit 40 is assembled to the slide door 13 in this way, as shown in FIGS. 3 to 6, in the vehicle front-rear direction, the fully open holding hook 43 is in the front and the intermediate stopper lever 44 is in the rear. Since the slide door 13 is opened by sliding backward, in other words, the intermediate stopper lever 44 is positioned on the door opening direction side of the fully open holding hook 43 with respect to the forward / backward direction of the slide door 13. Further, as shown in FIG. 6, the fully open holding hook 43 and the intermediate stopper lever 44 are offset in the vertical direction of the vehicle, the intermediate stopper lever 44 is upward (upper plate 41 side), and the fully open holding hook 43 is downward. Located on the lower plate 42 side.

  The operation of the above configuration will be described. First, the opening operation from the fully closed position of the slide door 13 in a state where the window glass 15 is closed will be described. FIG. 3 shows the fully closed state of the slide door 13. In FIG. 3, the body-side stopper unit 20 and the door-side stopper unit 40 are drawn closer to each other in the front-rear direction distance in the actual door fully closed state. At this time, in the door-side stopper unit 40, the fully open holding hook 43 is in the unlock position, and the intermediate stopper lever 44 is in the retracted position. The intermediate stopper lever 44 is in contact with the storage position holding member 14. Since the window glass 15 is closed, the cable 54 is in a relaxed state, and the second ratchet 46 in the door-side stopper unit 40 engages the engaging claw 46 a with the rotation restricting recess 44 b by the urging force of the urging spring 53. It is held at the rotation restriction position. Therefore, the intermediate stopper lever 44 is held at the retracted position against the urging force of the urging spring 51. Further, the cable 50 is loosened, and the first ratchet 45 is held at a position where the engagement claw 45a is brought into contact with the outer peripheral portion of the engagement preventing convex portion 43c of the fully open holding hook 43.

  When the sliding door 13 is slid in the opening direction along the lower rail 12, the door side stopper unit 40 moves together with the sliding door 13. When the slide door 13 approaches the open state, the intermediate stopper lever 44 approaches the intermediate stopper arm 27. However, when the intermediate stopper lever 44 is in the retracted position, the stopper contact portion 44a does not contact the intermediate stopper arm 27 (idle swing). Since the movement of the door-side stopper unit 40 is not restricted, the slide door 13 slides further toward the fully open position. When the slide door 13 approaches the fully open position, the fully open holding striker 26 enters the striker entry groove 43a. When the slide door 13 further moves in the opening direction, the fully open holding hook 43 is rotated from the unlocked position to the locked position against the biasing force of the biasing spring 47 by the moving force (FIG. 5). When the fully open holding hook 43 is rotated to the locked position, the first ratchet 45 is rotated counterclockwise as shown in FIG. 5 by the biasing force of the biasing spring 49, and the engagement claw 45a is engaged with the rotation restricting recess 43b. To do. In this engaged state, the rotation of the fully open holding hook 43 in the unlocking direction is restricted. As a result, the state where the fully open holding striker 26 is held in the striker entry groove 43a is maintained, and the sliding door 13 is restricted from sliding in the closing direction. The sliding door 13 is slid and locked in the opening direction to a position where the contact portion 31 of the lower arm 32 contacts the fully open stopper portion 22 a of the fully open stopper bracket 22. This is the door fully opened state of FIG. In FIG. 5, the engagement relationship between the striker entry groove 43 a and the fully open holding striker 26 is shown by a solid line to make it easy to see, but in reality, the engagement portion is in a position hidden under the base plate 21.

  To close the slide door 13 from this fully open state, the door handle is operated. Then, the cable 50 is pulled, and the first ratchet 45 is rotated clockwise in FIG. 5 against the biasing force of the biasing spring 49. Then, the engagement between the engaging claw 45a and the rotation restricting recess 43b is released, and the fully open holding hook 43 is allowed to rotate in the unlocking direction. Here, when the slide door 13 is slid in the opening direction, the fully opened holding hook 43 is rotated from the locked position to the unlocked position, and the fully opened holding striker 26 is detached from the striker entry groove 43a. Thereby, the fully open lock state of the slide door 13 is released, and the slide door 13 can be closed. When the window glass 15 is closed, the intermediate stopper lever 44 is kept in the retracted position during the above opening / closing operation of the slide door 13.

  Next, the opening operation from the fully closed position of the slide door 13 when the window glass 15 is opened more than a certain amount will be described. The point that the fully open holding hook 43 is in the unlocked position in the fully closed position of the slide door 13 is the same as the state in which the window glass 15 is closed. On the other hand, when the window glass 15 is opened more than a certain amount, the cable 54 is pulled according to the opening operation, and the second ratchet 46 is rotated in the clockwise direction in FIG. 3 against the urging force of the urging spring 53. Then, the engagement between the engaging claw 46a and the rotation restricting recess 44b is released, and the intermediate stopper lever 44 can be rotated to the protruding position.

  When the sliding door 13 is slid in the opening direction along the lower rail 12 in this state, the intermediate stopper lever 44 is separated from the storage position holding member 14 and is rotated to the protruding position shown in FIG. 4 by the urging force of the urging spring 51. Is done. When the slide door 13 approaches the open state, the stopper contact portion 44a of the intermediate stopper lever 44 protruding to the protruding position contacts the intermediate stopper portion 27a of the intermediate stopper arm 27. Since the intermediate stopper lever 44 abuts against the rotation restricting plate 52, the intermediate stopper lever 44 (the stopper abutting portion 44a) is restricted from rotating (clockwise in FIG. 4) beyond the protruding position. ) And the intermediate stopper arm 27 (intermediate stopper portion 27a), the further movement in the opening direction of the slide door 13 is restricted. That is, the slide door 13 is stopped at the intermediate open position before the fully open position. This is the door middle open state of FIG.

  In order to release the stop state at the intermediate open position, the window glass 15 may be closed and the slide door 13 may be slid to the fully closed position. When the window glass 15 is closed, the pulled state of the cable 54 is released. When the pulling of the cable 54 is released, the second ratchet 46 can be rotated according to the biasing force of the biasing spring 53. When the slide door 13 is returned to the fully closed position, the intermediate stopper lever 44 is pressed by the storage position holding member 14 (FIG. 3) and rotated from the protruding position to the storage position. Then, the second ratchet 46 is rotated counterclockwise in FIG. 4 by the urging force of the urging spring 53, the engaging claw 46a is engaged with the rotation restricting recess 44b, and the intermediate stopper lever 44 is held in the retracted position. The When returning from the intermediate open position, the window glass 15 may be closed first and then the slide door 13 may be slid to the fully closed position, or conversely, the slide door 13 may be slid to the fully closed position and then the window. The glass 15 may be closed.

  According to the above slide door structure, since both the full-open holding striker 26 and the intermediate stopper arm 27 are provided in the lower part of the boarding opening 11a, it is not necessary to provide a stopper member in the pillar portion extending in the vertical direction in the body 11. Therefore, the freedom degree of a body shape can be raised. Further, by forming the fully-open holding striker 26 and the intermediate stopper arm 27 as an integral body-side stopper unit 20 as in this embodiment, the number of parts can be reduced and a simple configuration can be achieved.

  Further, the positional relationship between the fully-open holding hook 43 and the intermediate stopper lever 44 in the door-side stopper unit 40 is arranged opposite to that of the conventional sliding door in the vehicle front-rear direction. Conventionally, with respect to the advancing / retreating direction of the slide door, a fully open holding hook is provided on the door opening direction side and an intermediate stopper lever is provided on the door closing direction side. On the other hand, in the slide door structure of the present embodiment, the intermediate stopper lever 44 is provided on the door opening direction (rear) side with respect to the fully open holding hook 43. This structure has the following advantages.

  As described in the description of the prior art, the reason for stopping the sliding door in the intermediate open position is to prevent the inserted object with the window glass opened from being sandwiched between the window frame of the sliding door and the body pillar. Because. Here, it is assumed that a distance A is required between the fully open position and the intermediate open position in the advancing / retreating direction of the slide door in order to prevent a specific target object from being caught. This distance A can be expressed as the amount of movement in the front-rear direction of the axial position of the fully opened holding hook (corresponding to the fully opened holding hook 43 in the embodiment) when the sliding door is in the fully opened position and the intermediate opened position. In the conventional type of stopper structure, the distance in the front-rear direction from the axial position of the fully open holding hook when the slide door is in the intermediate open position to the body side intermediate stopper member (corresponding to the intermediate stopper portion 27a of the embodiment) is B In this case, the front-rear distance C between the body-side intermediate stopper member and the body-side fully-open locking member (corresponding to the fully-open holding striker 26 of the embodiment) is the sum of the distance A and the distance B. (C = A + B). On the other hand, in the structure in which the front and rear are switched as in the present embodiment, the front-rear direction interval C ′ between the fully-open holding striker 26 and the intermediate stopper arm 27 is as follows. First, the distance between the fully open position and the intermediate open position in the forward / backward direction of the slide door 13 (the amount of movement of the support shaft 43x of the fully open holding hook 43) is A as in the above example. The distance in the front-rear direction from the axial position (support shaft 43x) of the fully open holding hook 43 when the slide door 13 is in the intermediate open position to the intermediate stopper portion 27a of the intermediate stopper arm 27 is assumed to be B as in the above example. Then, the relationship of A = B + C ′ is established. That is, C ′ = A−B, and even if the distance between the full-open holding striker 26 that is a full-open locking member and the intermediate stopper arm 27 that is an intermediate stopper is made closer, the sliding door 13 can be A necessary distance A can be ensured between the fully open position and the intermediate open position. This makes it possible to reduce the size of the stopper mechanism by reducing the distance between the fully-open holding striker 26 and the intermediate stopper arm 27 in the vehicle longitudinal direction. Since the fully-open holding striker 26 and the intermediate stopper arm 27 can be brought close to each other, as described above, the body-side stopper unit 20 in which the fully-opening stopper bracket 22, the fully-opening holding striker 26, and the intermediate stopper arm 27 are integrated is unitized. It is possible.

  The intermediate stopper lever 44 is positioned closer to the door opening direction than the fully open holding hook 43, so that when the slide door 13 moves to the fully open position beyond the intermediate open position, the fully open holding hook 43 is moved to the intermediate stopper arm 27. The striker entry groove 43a is engaged with the fully open holding striker 26 after passing through the installation position. Here, as shown in FIG. 6, the fully open holding hook 43 and the intermediate stopper lever 44 are provided with their positions offset in the vertical direction of the vehicle. Since the intermediate stopper arm 27 on the body 11 side is provided at the same height direction position as the stopper contact portion 44a of the intermediate stopper lever 44, as a result, the fully opened holding hook 43 and the intermediate stopper arm 27 are also offset in the vertical direction. It is in a positional relationship. Therefore, when the slide door 13 moves to the fully open position, the fully open holding hook 43 can move rearward from the intermediate stopper arm 27 without interfering with the intermediate stopper arm 27 and engage with the fully open holding striker 26. it can.
