The operation of the fully open stopper mechanism 65 will be described. When the sliding door is not fully open, the latch 81 is in a position (position shown in FIG. 5) that can be engaged with the fully open striker 69 by the biasing force of the torsion spring 81s.

The fully open striker 69 is engaged with the engagement groove 81a of the latch 81, and the latch 81 rotates in the direction opposite to the arrow F direction.
When the latch 81 rotates, the projection 83a of the second hook 83 is engaged with the projection 81b of the latch 81 by the spring 83s, prohibiting the rotation of the latch 81 in the direction of arrow F, and a fully open lock state is established.

To release this fully open lock state, the inside handle and outside handle are operated. Then, the cable 85 is pulled in, the engagement between the second hook 83 and the latch 81 is released, the latch 81 can be rotated in the direction of the arrow F, and the fully open lock state is released. For this reason, a slide door can be moved to a closing direction (for example, refer patent document 1).

(overall structure)
FIG. 1 is an exploded perspective view of the embodiment, and FIG. 2 is a diagram conceptually showing the basic configuration (plan view) of the fully open / intermediate stopper mechanism of the embodiment.

  In these drawings, the guide rail 151 is provided on the vehicle body side and is directed in the opening / closing direction of the sliding door. The rollers 153 and 155 are movably fitted to the guide rail 151 and are rotatably provided on the roller base 154. The roller base 154 is attached to a base plate 161 provided on the slide door. Thereby, the slide door is guided by the guide rail 151 and can move between the fully closed position and the fully open position.

  On the base plate 161, an intermediate stopper mechanism 163 that stops the sliding door that moves in the opening direction is provided, and a fully-open stopper mechanism 165 that holds the sliding door at the fully-open position. More specifically, the intermediate stopper mechanism 163 is provided on the intermediate stopper base 141, the fully open stopper mechanism 165 is provided on the fully open stopper base 143, and the intermediate stopper base 141 and the fully open stopper base 143 are mounted on the base plate 161. Further, the intermediate stopper mechanism 163 and the fully open stopper mechanism 165 are covered with an upper base 166.

  Here, the base plate 161 is located on the outer side (window side), and the guide rail 151 is located on the inner side (vehicle interior side). FIG. 2 shows a state where the slide door is in the fully closed position.

(Intermediate stopper mechanism)
As in the background art, an intermediate striker 167 that engages with the intermediate stopper mechanism 163 is provided on the vehicle body side. When the sliding door moves from the fully closed position toward the fully opened position, if the window glass is opened by a predetermined amount or more, the pole 171 of the intermediate stopper mechanism 163 and the intermediate striker 167 come into contact with each other. The movement in the above opening direction is restricted.

  Here, the intermediate stopper mechanism 163 will be described in detail. On the intermediate stopper base 141, a pole 171 capable of contacting the intermediate striker is disposed, and is rotatably supported by a pin 171c provided in the hole 141a of the intermediate stopper base 141. The pole 171 is urged in the direction of arrow D by a torsion spring 171s. Further, a buffer plate 171b is fixed to a contact portion of the pole 171 with the intermediate striker.

  Further, a first hook 173 is disposed on the intermediate stopper base 141 and is rotatably supported by a pin 173c provided in the hole 141b of the intermediate stopper base 141. The first hook 173 engages with the protrusion 171a of the pole 171 rotated to a position where it does not contact the intermediate striker with the protrusion 173a, and restrains the pole 171 at that position. The first hook 173 is urged in a direction E in which the protrusion 173a engages with the protrusion 171a of the pole 171 by a torsion spring 173s. When the protrusion 173a of the first hook 173 is engaged with the protrusion 171a of the pole 171, the rotation of the pole 71 in the arrow D direction is prohibited.

  Connected to the first hook 173 is a cable 175 driven by an intermediate stopper control mechanism described later. The outer casing 133 of the cable 175 is locked to the cable locking portion 141c of the intermediate stopper base 141.

  The pole push-back member 168 (see FIG. 2) is disposed on the vehicle body side. The pole push-back member 168 contacts the pole 171 in the slide door that is moving in the closing direction, and rotates the pole 171 from a position where it can contact the intermediate striker 167 to a position where it cannot contact.

  The stopper 177 protruding from the intermediate stopper base 141 is in contact with the pole 171 whose restriction by the first hook 173 is released, and stops the pole 171 at this contact position.

(Fully open stopper mechanism)
The fully open stopper mechanism 165 will be described in detail.
As shown in FIG. 2, a full-open striker 169 that engages with the full-open stopper mechanism 165 when the slide door moves to the full-open position is disposed on the vehicle body side.

  On the other hand, the fully open stopper base 143 is provided with a latch 181 in which an engagement groove 181 a that can be engaged with and disengaged from the fully open striker 169 is disposed, and can be rotated by a pin 181 c provided in the hole 143 c of the fully open stopper base 143. It is supported. The latch 181 is urged in the direction of arrow F by a torsion spring 181s (see FIG. 1) and abuts against a stopper portion 143d formed on the fully open stopper base 143. Here, the position of the latch 181 shown in FIG. 2 is a position (lock position) that can be engaged with the fully-open striker 169.

  The fully opened stopper base 143 is provided with a second hook 183 and is rotatably supported by a pin 183c provided in the hole 143e of the fully opened stopper base 143. The second hook 183 has one end locked to the fully open stopper base 143 and the other end locked to the second hook 183 by a spring 183 s so that the protrusion 183 a is engaged with the protrusion 181 b of the latch 181. It is biased in the direction G. The operating force of the inner handle and the outer handle is transmitted to the second hook 183 via the cable 185. The outer casing 134 of the cable 185 is locked to the cable locking portion 143k of the fully open stopper base 143.

(Whole assembly)
As shown in FIG. 1, the pins 171 c and 173 c of the intermediate stopper mechanism engage with the holes 166 a and 166 b of the upper base 166.

The pins 181c and 183c of the fully open stopper mechanism 165 are engaged with the holes 166d and 166e of the upper base 166.
Then, the hole 166f of the upper base 166, the hole 177a of the stopper 177 on the intermediate stopper base 141, the hole (not shown) of the intermediate stopper base 141, and the hole 161f of the base plate 161 are inserted into the roller base 154 and are thus screwed. The base plate 161 includes a screw 201 screwed into the hole 154a, a long hole 166h in the upper base 166, and a long hole 143g in the fully open stopper base 143, and a screw 205 formed in the base plate 161 and screwed into the screw hole 161h. The intermediate stopper mechanism 163, the fully open stopper mechanism 165, and the upper base 166 are integrated.

Further, a screw 207 is inserted into the long hole 161 i of the base plate 161 and screwed into the female screw hole 154 b of the roller base 154.
As shown in FIG. 3, a resin cover 301 having a clip portion 301 a that can be engaged with a locking hole 166 g formed in the upper base 166 is provided on the upper base 166 to cover the base plate 161 and the upper base 166. I am doing so.

(Operation of the intermediate stopper mechanism)
The operation of the intermediate stopper mechanism 163 will be described.
When the sliding door is in the fully closed position and the window glass is in the fully closed state, as shown in FIG. 2, the first hook 173 is connected to the pole 171 rotated to a position where it cannot contact the intermediate striker 167. It is engaged by the urging force of 73s.

  Here, when the window glass is lowered to a predetermined position, the cable 175 is pulled in by an intermediate stopper control mechanism (not shown), and the first hook 173 is driven in the direction of separating from the pole 171 (clockwise in FIG. 2). When the window glass exceeds a predetermined position, the engagement with the pole 171 is released. As a result, when the pole push-back member 168 is not restrained, the pole 171 rotates until it comes into contact with the stopper 177 by the urging force of the torsion spring 171s, and can come into contact with the intermediate striker 167.

  When the sliding door with the window glass lowered to a predetermined position is moved in the opening direction, the pole 171 moves away from the pole pushing-back member 168 as it moves, and thus rotates until it comes into contact with the stopper 177. When further moved, the pole 171 comes into contact with the intermediate striker 167 and enters an intermediate locked state. Thereby, the movement of the slide door is prohibited on the way.

  Here, to release the intermediate lock state, the slide door is moved in the closing direction and the window glass is raised from a predetermined position. As a result, the back surface of the pole 171 is pushed by the pole push-back member 168 provided on the vehicle body side, the pole 171 rotates in the direction opposite to the arrow D, and the first hook 173 engages with the pole 171 again, and the intermediate lock The state is released.

(Operation of fully open stopper mechanism)
The operation of the fully open stopper mechanism 165 will be described. When the sliding door is not fully opened, the latch 181 is in a position where it can engage with the fully open striker 169 (position shown in FIG. 2) by the urging force of the torsion spring 181s.

The fully open striker 169 is engaged with the engagement groove 181a of the latch 181, and the latch 181 rotates in the direction opposite to the arrow F direction.
When the latch 181 rotates, the protrusion 183a of the second hook 183 engages with the protrusion 181b of the latch 181 by the spring 183s, prohibiting the rotation of the latch 181 in the direction of arrow F, and a fully open lock state is established.

  To release this fully open lock state, the inside handle and outside handle are operated. Then, the cable 185 is pulled in, the engagement between the second hook 183 and the latch 181 is released, the latch 181 can be rotated in the direction of the arrow F, and the fully open lock state is released. For this reason, the slide door can be moved in the closing direction.

  According to such a configuration, the fully opened stopper base 143 is attached with the fully opened stopper mechanism 165 and the outer casing 134 of the cable 185 that unlocks the fully opened stopper mechanism 165, so that the assembly (unit) of the fully opened stopper mechanism is provided. Composed.

  Similarly, since the intermediate stopper mechanism 163 and the outer casing 133 of the cable 175 that unlocks the intermediate stopper mechanism 163 are attached to the intermediate stopper base 141, an assembly (unit) of the intermediate stopper mechanism 163 is configured.

  Accordingly, when diverting to another vehicle in which the positional relationship between the fully open stopper mechanism 165 and the intermediate stopper mechanism 163 is different, only the upper base 166 may be remade for another vehicle, and diverted to another vehicle at a low cost.

Further, even when only the intermediate stopper mechanism 163 or only the fully open stopper mechanism 165 can be set.
Furthermore, the appearance is improved by providing the resin cover 301 that covers the base plate 161 and the upper base 166. At this time, the upper base 166 only needs to satisfy the function, and it is not necessary to consider the aesthetic appearance (shape and painting), so the cost of the upper base 166 can be reduced. Furthermore, since it is the resin cover 301, a shape, a color, etc. can be set at low cost.

  Further, when the resin cover 301 is not provided, the upper base 166 is a part that can be visually recognized from the outside. However, in this embodiment, the cable 175, the outer casing 133 of the cable 185, and the outer casing 134 are locked. Since it becomes unnecessary, the aesthetics are improved over the conventional upper cover.

It is a disassembled perspective view of the form example. It is a figure which shows notionally the fundamental structure (plan view) of the full open and intermediate | middle stopper mechanism of a form example. It is explanatory drawing of a resin cover. It is a figure explaining the sliding door of a vehicle. It is a figure which shows notionally the basic composition (plan view) of the conventional full open / intermediate stopper mechanism.
