Description

  The present invention relates to a slide door having an intermediate stopper mechanism that stops a slide door that moves in an opening direction and a fully-open stopper mechanism that prohibits movement of the slide door at a fully-open position.

  As shown in FIG. 9, a wind glass 1 is provided on a slide door 3 such as a vehicle so as to be movable up and down. Therefore, when the sliding door 3 is opened with the window glass 1 lowered, if an object is inserted into the window of the sliding door 3, the object is sandwiched between the window frame 7 and the pillar 9 of the sliding door 3. May be damaged.

  Therefore, in order to avoid this situation, it has been proposed to provide an intermediate stopper mechanism and stop the sliding door that is moving in the opening direction in the middle of opening when the window glass 1 is lowered below a predetermined position. .

An example of this sliding door is shown in FIG.
First, the intermediate stopper control mechanism 11 pulls in the cable (inner cable) 13 when the window glass 1 is lowered by a predetermined amount L (for example, 150 mm) from the fully closed state.

  The intermediate stopper mechanism 15 is connected to the intermediate stopper control mechanism 11 by a cable 13. The intermediate stopper mechanism 15 is driven by the intermediate stopper control mechanism 11 and stops the slide door 3 moving in the opening direction in the middle of opening. The window regulator 16 drives the window glass 1 in the vertical direction.

  As an example of the intermediate stopper mechanism 15, there is a configuration as shown in FIG. In the figure, a roller 23 provided on the slide door side is movably engaged with the lower rail 21 provided on the vehicle body side, and the slide door is movable along the lower rail 21. An intermediate stopper mechanism 27 and a fully open stopper mechanism 29 are provided on the base 25 on the slide door side. On the other hand, an intermediate stopper 33 that can contact the intermediate hook 31 of the intermediate stopper mechanism 27 and a striker 37 that can engage and disengage the fully open hook 35 of the fully open stopper mechanism 29 are provided on the vehicle body side.

When the intermediate stopper (not shown) is actuated, the cable 41 is pulled and the ratchet 43 engaged with the intermediate hook 31 is detached from the intermediate hook 31 as shown in FIG. The intermediate hook 31 biased in the direction of the arrow A rotates until it comes into contact with the stopper pin 45, and can come into contact with the intermediate stopper 33 (see, for example, Patent Document 1).
JP 2001-136664 A (FIGS. 1 and 2)

  However, in the intermediate stopper mechanism 27 configured as shown in FIG. 11, when the slide door is vigorously opened in a state where the intermediate hook 31 of the intermediate stopper mechanism 27 can contact the intermediate stopper 33 (the state shown in FIG. 12), After the intermediate hook 31 comes into contact with the intermediate stopper 33, the slide door may not be stopped on the spot and bounces back.

  In order to prevent the sliding door from rebounding at the intermediate stop position, the fully opened hook 35 is driven in conjunction with the movement of the intermediate hook 31 of the intermediate stopper mechanism 27. It is also conceivable to prevent the sliding door from bouncing by sandwiching the intermediate stopper 33. However, in this case, there is a problem that the fully open hook 35 must be disposed at a position where it can contact the intermediate stopper 33, and the degree of freedom in designing the fully open stopper mechanism is lost.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a slide door that does not rebound when the intermediate stopper mechanism is operated and has a degree of design freedom.

  The invention according to claim 1, which solves the above problem, includes an intermediate stopper mechanism that stops the slide door that moves in the opening direction halfway, and a fully open stopper mechanism that prohibits movement of the slide door at the fully open position. In the intermediate stopper mechanism, the first intermediate stopper, the second intermediate stopper, and the window glass of the slide door, which are provided at intervals along the opening direction of the slide door on the vehicle body side. It is driven by an intermediate stopper control mechanism that operates when a predetermined amount is lowered from the closed state, and has an intermediate hook that can come into contact with each other between the first intermediate stopper and the second intermediate stopper when driven. It is a sliding door.

  When the window glass of the slide door is lowered by a predetermined amount from the fully closed state, the intermediate hook is driven by the intermediate stopper control mechanism, and can come into contact between the first intermediate stopper and the second intermediate stopper. That is, the intermediate hook on the slide door side is sandwiched between the first intermediate stopper and the second intermediate stopper on the vehicle body side.

  The invention according to claim 2 is a slide door having an intermediate stopper mechanism that stops the slide door that moves in the opening direction halfway, and a fully open stopper mechanism that prohibits the movement of the slide door at the fully open position, The full-open stopper mechanism is provided on the striker provided on the vehicle body side and on the slide door side, the groove is formed, and the striker that has entered the groove from the unlock position where the striker can enter the groove is provided. A fully open hook that can rotate between a fully locked position that prohibits disengagement from the groove, and the fully open hook that is provided on the slide door side and that is in the unlocked position, so that the fully opened hook can be rotated further. A fully open hook stopper to be prohibited, and a first biasing means provided on the slide door side and biasing the fully open hook toward the fully open hook stopper; Provided on the sliding door side, engageable with the hook in the full lock position, and prohibiting the hook from rotating in the unlock position direction, and operating the door handle of the slide door A fully-open ratchet that is driven in a direction away from the hook, and a second biasing means that is provided on the slide door side and biases the fully-open ratchet in the hook direction. And a second intermediate stopper that protrudes toward the slide door from the first intermediate stopper, and is provided at a distance along the opening direction of the slide door. And can be brought into contact with the second stopper from a retracted position provided on the slide door side and not in contact with the first and second intermediate stoppers. An intermediate hook that is rotatable between a half stop position and a full stop position that can contact the first and second intermediate stoppers, and the intermediate hook that is provided on the slide door side and is in the full stop position An intermediate hook stopper that prohibits further rotation of the intermediate hook, a third urging means that is provided on the slide door side and urges the intermediate hook toward the intermediate stopper, Provided on the sliding door side, engageable with the intermediate hook in the retracted position, and operates when the window glass of the sliding door is lowered by a predetermined amount from the fully closed state so as to be detached from the intermediate hook by an intermediate stopper control mechanism. A first ratchet to be driven; fourth biasing means for biasing the first ratchet in a direction to engage the intermediate hook; Provided on the door side, engageable with the intermediate hook at the half-stop position and the full-stop position, and when the fully-open ratchet is driven by the door handle, in a direction to detach from the intermediate hook in conjunction with each other. A second ratchet to be driven, a ratchet stopper provided on the slide door side and prohibiting further rotation of the second ratchet at a position not engaged with the intermediate hook; and the second ratchet is connected to the ratchet stopper. The sliding door is characterized by comprising a fifth urging means for urging in a direction in which the urging member abuts against the sliding door.

  When the sliding door is in the fully closed position and the window glass is closed, the intermediate stopper control mechanism does not operate. At this time, the first ratchet biased by the fourth biasing means is engaged with the intermediate hook biased in the retracted position direction by the second biasing means of the intermediate stopper mechanism, The retracted position is not in contact with the second intermediate stopper. At this time, the second ratchet is in contact with the ratchet stopper by the fifth urging means and is in a position not engaged with the first ratchet.

The fully open hook of the fully open stopper mechanism is in contact with the fully open hook stopper by the first biasing means and is in the unlock position.
In this state, when the sliding door is opened and the sliding door moves to the fully opened position, the striker enters the groove of the fully opened hook of the fully opened stopper mechanism, and the fully opened hook is fully locked against the urging force of the first urging means. Rotating in the position direction, the fully-open ratchet is engaged, and the fully-locked state in which the rotation of the fully-open ratchet to the unlock position is prohibited.

  To release this full lock state, the door handle of the slide door is operated. Then, the fully opened ratchet is driven in a direction away from the fully opened hook against the urging force of the second urging means, and the fully opened hook is rotated to the unlock position where it abuts against the fully opened hook stopper by the urging force of the first urging means. It will be unlocked.

  When the sliding door is in the fully closed position and the window glass is lowered from the fully closed state by a predetermined amount, the intermediate stopper control mechanism is activated, and the first ratchet is driven in the direction to detach from the intermediate hook. By the urging force of the third urging means, it rotates in the full stop position direction. Then, the intermediate hook engages with the second ratchet that is urged by the fifth urging means and is in contact with the ratchet stopper, and the intermediate hook is in the half stop position.

  When the sliding door is opened in this state, the intermediate hook passes through the first intermediate stopper and abuts on the second intermediate stopper. At this time, the intermediate hook pushed by the second intermediate stopper rotates to the full stop position where it abuts against the intermediate hook stopper, the second ratchet is engaged again, and the intermediate hook can abut against the first and second stoppers. Full stop position. That is, the intermediate stopper is in a state of being sandwiched between the first and second stoppers, and is in an intermediate stop state in which movement of the sliding door in the opening direction and further in the closing direction is prohibited.

  To release this state, the door handle of the sliding door is operated. Then, the fully open ratchet of the fully open stopper mechanism is driven, and when the second ratchet is driven in a direction to move away from the intermediate hook, the intermediate hook Can rotate in the retracted position direction, and when the sliding door is moved in the closing direction, the sliding door can be moved in the closing direction over the first intermediate stopper.

  According to the first and second aspects of the invention, when the intermediate stopper mechanism is operated, the intermediate hook on the slide door side is sandwiched between the first intermediate stopper and the second intermediate stopper on the vehicle body side. Become. That is, the movement of the sliding door in the opening direction is prohibited by the second intermediate stopper, and the movement of the sliding door in the closing direction is prohibited by the first intermediate stopper, so that the sliding door does not rebound.

  Furthermore, since such an effect can be obtained with only the intermediate stopper mechanism, the degree of freedom in design is great.

Embodiments of the present invention will be described with reference to the drawings.
First, the overall configuration will be described with reference to FIG. In the figure, a roller 105 provided on the slide door side is movably engaged with a lower rail 103 provided on the vehicle body side, and the slide door is movable along the lower rail 103. Note that when the slide door moves from the left to the right of the page, the slide door moves from the closed state to the open state. An intermediate stopper mechanism 201 and a fully open stopper mechanism 301 are provided on the base 101 on the slide door side. On the other hand, the intermediate hook 203 of the intermediate stopper mechanism 201 can be brought into contact with the vehicle body side, and a first intermediate stopper 205 and a second intermediate stopper 207 projecting toward the slide door are provided, and the fully open stopper mechanism 301 is fully opened. A striker 305 capable of engaging and disengaging the hook 303 is provided. The first intermediate stopper 205 and the second intermediate stopper 207 are provided at intervals along the opening direction of the slide door (in the direction of arrow B in the figure), and the second intermediate stopper 207 is the first intermediate stopper 205. It is set so as to further protrude toward the sliding door side (the height is high).

  Further, when the sliding door is closed, the intermediate hook 203 at the stop position (the stop position will be described later) of the intermediate stopper mechanism 201 comes into contact with the vehicle body side, and the storage pin that guides the intermediate hook 203 to the storage position. 131 is provided.

Next, the full-open stopper mechanism 301 and the intermediate stopper mechanism 201 will be described with reference to FIG.
(Fully open stopper mechanism 301)
The fully-open hook 303 provided with the groove 311 uses the pin 313 on the base 101 and the striker that has entered the groove 311 from the unlock position (the position shown in FIGS. 1 and 2) where the striker 305 can enter the groove 311. It can rotate between a full lock position (position shown in FIG. 3) that prohibits 305 from being removed from the groove 311. Further, the base 101 is provided with a fully open hook stopper 315 that can contact the fully open hook 303 in the unlock position and prohibits further rotation of the fully open hook 303. Then, for example, by a spring (first urging means) (not shown) having one end locked to the base 101 and the other end locked to the fully opened hook 303, the fully opened hook 303 is moved toward the fully opened hook stopper 315 (arrow C). Direction).

  A fully open ratchet 323 is rotatably provided on the base 101 using a pin 321. For example, the fully open ratchet 323 is moved toward the fully open hook 303 by a spring (second biasing means) (not shown) having one end locked to the base 101 and the other end locked to the fully open ratchet 323. Energized in the direction of arrow D). The engaging portion 323a formed on one rotation end side of the fully open ratchet 323 can be engaged with the engaging portion 303a of the fully open hook 303 in the full lock position, and is in the full lock position by engaging. The rotation of the fully open hook 303 in the unlock position direction is prohibited.

Further, a cable 331 operated by a door handle of the sliding door is connected to the other rotating end side of the fully open ratchet 323, and the fully open ratchet 323 is attached to the second urging means by operating the door handle. The engaging portion 323a rotates in a direction to be separated from the fully opened hook 303 against the force.
(Intermediate stopper mechanism 201)
The intermediate hook 203 of the intermediate stopper mechanism 201 uses a pin 211 with respect to the base 101 to move from the retracted position (position shown in FIGS. 1 and 2) where it does not contact the first intermediate stopper 205 and the second intermediate stopper 207. A full stop that can contact the first intermediate stopper 205 and the second intermediate stopper 207 via a half stop position (see FIG. 4) that can contact the second intermediate stopper 207 without contacting the first intermediate stopper 205. It is rotatably provided up to the position (see FIGS. 5 and 6). Further, the base 101 is provided with an intermediate hook stopper 213 that can contact the intermediate hook 203 at the full stop position and prohibits further rotation of the intermediate hook 203. For example, the intermediate hook 203 is moved in the direction of the intermediate hook stopper 213 (arrow E) by a spring (third biasing means) (not shown) having one end locked to the base 101 and the other end locked to the intermediate hook 203. Direction).

  A first ratchet 223 and a second ratchet 233 are rotatably attached to the base 101 from the base 101 side using pins 221. The first ratchet 223 is formed with an engaging portion 223 a that can be engaged with the intermediate hook 203, and the second ratchet 233 is formed with an engaging portion 233 a that can be engaged with the intermediate hook 203. The first ratchet 223 is connected to a cable 225 that is pulled when an intermediate stopper control mechanism (not shown) that operates when the window glass of the sliding door is lowered by a predetermined amount from the fully closed state is driven. The base 101 is formed with a ratchet stopper 231 that prohibits further rotation of the second ratchet 233 at a position not engaged with the intermediate hook 203.

  For example, the first ratchet 223 has an engaging portion 223a by an unillustrated spring (fourth biasing means) whose one end is locked to the base 101 and the other end is locked to the first ratchet 223. It is urged in a direction in which the intermediate hook 203 abuts (in the direction of arrow F). Similarly, for example, the second ratchet 233 is brought into contact with the ratchet stopper 231 by a spring (fifth biasing means) (not shown) having one end locked to the base 101 and the other end locked to the second ratchet 233. It is biased in the direction of contact (the direction of arrow G).

As shown in FIG. 8, which is a perspective view of the intermediate hook of FIGS. 1 and 2 as seen from the back side, the intermediate hook 203 is formed with a total of three engaging portions that can engage the first ratchet and the second ratchet. Has been. That is, the engagement portion 223a of the first ratchet 223 that is not driven by the intermediate stopper control mechanism can be engaged, and the engagement position of the intermediate hook 203 is maintained by the engagement. The engaging portion 233a of the second ratchet 233 can be engaged, and the engaging portion 233a of the second ratchet 233 is engaged with the second engaging portion 203b that holds the half stop position of the intermediate hook 203 by engaging. And a third engagement portion 203c that holds the full stop position of the intermediate hook 203 when engaged.

Further, the second ratchet 233 is provided with a pin 237 with which the fully open ratchet 323 driven by the door handle can come into contact.
Next, the operation of the above configuration will be described.
(Sliding door fully closed, window glass fully closed)
As shown in FIG. 2, the engaging portion 223a of the first ratchet 223 is engaged with the first engaging portion 203a of the intermediate hook 203 of the intermediate stopper mechanism 201, and is in the retracted position.

Further, the fully open hook 303 comes into contact with the fully open hook stopper 315 by the urging force of the spring (first urging means), and the striker 305 is in an unlocked position where the striker 305 can enter the groove 311.
(When the sliding door is opened with the glass window fully closed)
If the glass window remains fully closed, the intermediate stopper control mechanism does not operate, and the intermediate hook 203 remains in the retracted position where it does not contact the first intermediate stopper 205 and the second intermediate stopper 207. The mechanism 201 does not operate. Therefore, when the sliding door is moved to the fully open position, the striker 305 on the vehicle body enters while pushing the wall surface of the groove 311 of the fully open hook 303 at the unlock position of the fully open stopper mechanism 301 as shown in FIG. The hook 303 rotates against a biasing force of a spring (first biasing means) (not shown) to the full lock position where the striker 305 that has entered the groove 311 is prohibited from being detached. Then, the engaging portion 323a of the fully-open ratchet 323 is engaged with the engaging portion 303a of the fully-opening hook 303, and the fully-locked state in which the rotation of the fully-opening hook 303 in the unlock position direction is prohibited.

To release this full lock state, the door handle of the slide door is operated. Then, the cable 331 is pulled, and the fully open ratchet 323 is driven in a direction away from the fully open hook 303 against the urging force of a spring (second urging means) (not shown), so that the fully open ratchet 323 and the fully open hook 303 are engaged. The fully opened hook is rotated to the unlock position where it abuts against the fully opened hook stopper 315 by the urging force of a spring (first urging means) (not shown), and the unlocked state is established.
(When the sliding door is opened with the glass window lowered by a predetermined amount from the fully closed position)
When the glass window is lowered from the fully closed position by a predetermined amount from the state shown in FIG. 2, the state shown in FIG. 4 is obtained. That is, when the glass window is lowered, the intermediate stopper control mechanism is actuated, the cable 225 is pulled, and the first ratchet 223 is driven in a direction to detach from the intermediate hook 203. It rotates in the direction of the full stop position by the biasing force of the biasing means. Then, the second engagement portion 203b of the intermediate hook 203 is engaged with the engagement portion 233a of the second ratchet 233 that is urged by a spring (fifth urging means) (not shown) and is in contact with the ratchet stopper 231. The intermediate hook 203 does not come into contact with the first intermediate stopper 205 but is in a half stop position where it can come into contact with the second intermediate stopper 207.

  In this state, when the sliding door is opened, the intermediate hook 203 passes through the first intermediate stopper 205 and comes into contact with the second intermediate stopper 207. Further, when the sliding door is moved in the opening direction, as shown in FIG. 5, the intermediate hook 203 pushed by the second intermediate stopper 207 rotates in a direction to contact the intermediate hook stopper 213, and the second ratchet 233 is moved. The engagement between the engagement portion 233a and the second engagement portion 203b of the intermediate hook 203 is released, and the intermediate hook 203 rotates to the full stop position where it abuts against the intermediate hook stopper 213. At this time, the engaging portion 233 a of the second ratchet 233 engages with the third engaging portion 203 c of the intermediate hook 203. At this time, the intermediate hook 203 is in an intermediate stop state sandwiched between the first intermediate stopper 205 and the second intermediate stopper 207. In this state, when the sliding door is moved in the opening direction (see FIG. 5), the intermediate hook 203 contacts the second intermediate stopper 207, and the intermediate hook 203 contacts the intermediate hook stopper 213. Movement of the sliding door in the opening direction is prohibited. Further, when the sliding door is moved in the closing direction (see FIG. 6), the intermediate hook 203 comes into contact with the first intermediate stopper 205, and the engaging portion 233a of the second ratchet 233 and the third engaging portion of the intermediate hook 203 Due to the engagement with 203c, further movement of the sliding door in the closing direction is prohibited.

  To release this state, the door handle of the sliding door is operated. Then, as shown in FIG. 7, the cable 331 is pulled, the fully-open ratchet 323 of the fully-open stopper mechanism 301 is driven, and the second ratchet 233 of the intermediate stopper mechanism 201 is driven in a direction to be detached from the intermediate hook 203. The More specifically, when the cable 331 is pulled, the fully open ratchet 323 rotates against a biasing force of a spring (second biasing means) (not shown) and pushes the pin 237 of the second ratchet 233 of the intermediate stopper mechanism 201. As a result, the second ratchet 233 rotates against the urging force of a spring (fifth urging means) (not shown), and the engagement portion 233a is disengaged from the third engagement portion 203c of the intermediate hook 203 to engage. Is released. For this reason, the intermediate hook 203 can rotate in the direction opposite to the arrow E direction, and when the sliding door is moved in the closing direction, the intermediate hook 203 gets over the first intermediate stopper 205 and moves the sliding door in the closing direction. Can do. When the sliding door is closed, the intermediate hook 203 is rotated to the storage position by the storage pin 131. Here, when the window glass is closed, the cable 225 is returned by the intermediate stopper control mechanism, and the engaging portion 223a of the first ratchet 223 is engaged with the first engaging portion 203a of the intermediate hook 203 in the retracted position, The state shown in FIG. 2 is obtained. Note that the window glass may be closed at any time, for example, before the door handle is operated.

According to the above configuration, the following effects can be obtained.
(1) When the intermediate stopper mechanism 201 is operated, the intermediate hook 203 on the slide door side is sandwiched between the first intermediate stopper 205 and the second intermediate stopper 207 on the vehicle body side. That is, the movement of the sliding door in the opening direction is prohibited by the second intermediate stopper 207, and the movement of the sliding door in the closing direction is prohibited by the first intermediate stopper 205, so that the sliding door does not rebound.
(2) Since the effect as shown in (1) can be obtained only by the intermediate stopper mechanism 201 regardless of the fully open stopper mechanism 301, the degree of freedom in design is great.
