DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide door stopper mechanism having an intermediate stopper function for stopping a slide door moving in an opening direction and a full open stopper function for inhibiting movement of the slide door in a fully open position. About.

[0002]

2. Description of the Related Art As shown in FIG. 7, a window glass 1 is provided on a slide door 3 of a vehicle or the like so as to be able to move up and down. For this reason, 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 removed from the window frame 7 of the sliding door 3.
And the pillar 9 and may be damaged.

In order to avoid this situation, a stopper mechanism (intermediate stopper mechanism) having an intermediate stopper function for stopping the slide door halfway is provided, and when the window glass 1 is lowered below a predetermined position, the opening direction is reduced. It has been proposed to stop a sliding door that is moving during the opening process.

The slide door shown in FIG. 8 incorporates an intermediate stopper control mechanism 11, an intermediate stopper mechanism 15, an X-arm type window regulator 16, and the like. First, the intermediate stopper control mechanism 11 moves the window glass 1 from the fully closed state to a predetermined amount L (for example, 150 mm).
mm), the cable (inner cable) 13 is drawn in according to the amount of the drop. When the moving stroke of the cable 13 reaches the set value, the drawing of the cable 13 is stopped. However, even in this situation, the window glass 1 can descend.

[0005] The intermediate stopper mechanism 15 is connected to the intermediate stopper control mechanism 11 via a cable 13. The intermediate stopper mechanism 15 is driven by the intermediate stopper control mechanism 11 and stops the sliding door 3 that moves in the opening direction during opening. Also, X
The arm type window regulator 16 drives the window glass 1 in the vertical direction.

Here, the intermediate stopper control mechanism 1
1 will be described with reference to FIG. A base plate 31 is fixed to the inner panel of the slide door 3, and pins 33 are erected on the base plate 31. A first lever 35 and a second lever 37 are rotatably attached to the pin 33.

The spiral spring 39 has a pin 3
3, one end 39a is hooked on the first lever 35, and the other end 39b is wound on the second lever 37.
Hanged on.

A roller 41 is provided at the rotating end of the first lever 35, and the roller 41 is engaged with the guide 17 provided below the window glass 1 so as to be movable in the horizontal direction in the figure. are doing. The cable 13 is connected to the second lever 37.

Next, the structure of the intermediate stopper mechanism 15 is shown in FIG.
Explanation will be made using 0. A base plate 21 is fixed to a lower portion of the inner panel of the slide door 3, and a lever 22 is rotatably mounted on the base plate 21. The lever 22 is connected to the cable 13 and
It is urged in the direction of arrow I by urging means (not shown). A roller 2 having elasticity is provided at the tip of the lever 22.
4 are provided. On the other hand, the roller 2
The step part 28 which can contact with 4 is formed.

When the window glass 1 in the fully closed state is lowered by using the window regulator 16 in the slide door 3, the first lever 35 also rotates counterclockwise in FIG. I do.
Since the second lever 37 is also connected to the first lever 35 via the spiral spring 39, the second lever 37 rotates counterclockwise to draw in the cable 13.

When the movement stroke of the cable 13 reaches the set value, the rotation of the second lever 37 is restricted, and
It becomes impossible to rotate following the first lever 35. However, even in this situation, the spiral spring 39
Is elastically deformed so as to reduce the diameter of the first lever 3.
Only 5 can be rotated counterclockwise, and the window glass 1 can be lowered.

Therefore, when the window glass 1 is lowered from the fully closed state by a predetermined amount L or more, the intermediate stopper control mechanism 11 pulls in the cable 13 by a predetermined amount and the lever 2
2 rotates against the urging force of the urging means (not shown), and moves from the two-dot chain line position to the solid line position in FIG.

When the sliding door 3 is moved in the opening direction in this state, the roller 24 comes into contact with the step 28 on the vehicle body side, stops at that position, and the sliding door 3 cannot be opened any more. That is, even if the window glass 1 is lowered and an object is inserted into the window of the slide door 3, in this situation, a space always exists between the window frame 7 of the slide door 3 and the pillar 9, A situation where an object inserted into the window is pinched can be avoided.

The slide door 3 incorporates not only the intermediate stopper mechanism 15 but also a fully-open stopper mechanism that exhibits a fully-open stopper function, so that the slide door 3 can be locked at the fully-open position. As shown in FIG. 11, a conventionally known full-open stopper mechanism partially protrudes into the guide rail 23 on a vehicle-body-side guide rail 23 on which a roller 27 provided on the slide door 3 is movably engaged. A leaf spring 25 is provided, and the roller 27
The slide door 5 is elastically deformed and reaches the fully open position, thereby holding the slide door at the fully open position.

[0015]

The intermediate stopper mechanism and the fully-open stopper mechanism have the following disadvantages. Since the intermediate stopper mechanism and the fully-open stopper mechanism are independent mechanisms, the space occupied by both of them is increased.

When the window glass 1 is lowered from the fully closed state in the intermediate stopper mechanism, the intermediate stopper control mechanism 11 gradually pulls the cable 13 before the window glass 1 reaches the predetermined amount L.
Also slowly rotates. Therefore, when the slide door 3 is strongly pulled in the opening direction in a state where the lowering of the window glass 1 is slightly smaller than the predetermined amount L, the roller 24 abuts on the step portion 28 and then goes over the step portion 28, and the slide door 3 It moves to the fully open position.

That is, at the time of the switching operation of the intermediate stopper mechanism 15, the roller 24 is in a halfway state, and in this halfway state, the roller 24 advances over the step portion 28. When sliding the slide door 3 in this state, the roller 24, the lever 22, the base plate 21
A large load is applied to these parts, and not only the durability of these parts is reduced, but also abnormal noise is generated, the opening operation force of the slide door 3 is increased, and the operation feeling is deteriorated.

Further, when the window glass 1 is lowered by a predetermined amount L or more, it is necessary that the roller 24 surely hits the step 28 on the vehicle body side to stop the slide door 3.
However, since the roller 24 is in a half-finished state in a wide range, the base plate 21 needs
It is absolutely necessary to adjust the mounting state of the device by trial and error.

Regarding the fully-open stopper mechanism, in order for the fully-open stopper mechanism to shift to the unlocked state or the locked state, the roller 27 needs to ride over the leaf spring 25,
At this time, a large operation force is required. Further, since the movement of the roller 27 is prohibited by the leaf spring 25 having low rigidity, the force for holding the slide door 3 at the fully open position is weak.

An object of the present invention is to provide a stopper mechanism which has solved the above-mentioned drawbacks. That is, a first object of the present invention is to provide a stopper mechanism for a slide door capable of saving space. A second object of the present invention is to provide a stopper mechanism for a slide door that does not cause an incomplete state when switching between starting and stopping the operation of the intermediate stopper function. A third object is to provide a slide door stopper mechanism that can reduce the opening / closing operation force of the slide door and can hold the slide door at a fully open position with a strong force.

[0021]

According to a first aspect of the present invention, there is provided an intermediate stopper function for stopping a sliding door moving in an opening direction, and a fully opening function for inhibiting the sliding door from moving in a fully open position. A stopper mechanism for a slide door having a stopper function, wherein an intermediate striker and a fully open striker are provided on the vehicle body side so as to be displaced in the width direction of the slide door, and a latch return member is provided. An arm portion which is arranged so that a rotation center axis draws a movement trajectory passing between the intermediate striker and the full-open striker displaced in the width direction of the door, and an outer peripheral portion capable of contacting the intermediate striker and the full-open striker; The arm portion does not come into contact with the intermediate striker, and the lock groove portion engages with the fully opened striker. A neutral rotation position, a first rotation position at which the arm portion rotates from the neutral rotation position to the intermediate striker side, and can contact the intermediate striker, and is pushed by the fully open striker engaged with the lock groove portion. Then, the lock groove rotates from the neutral rotation position to the fully opened striker side, and can be moved between three rotation positions of a second rotation position where the lock groove and the fully opened striker are engaged. When returning to the closed position, the first

As a result, the latch is rotated to the neutral rotation position by the urging force of the first urging means, and the engagement between the lock groove and the fully opened striker is released.

When the sliding door is in the fully closed position and the window glass is in the fully closed state, if the window glass is lowered to a predetermined position, the latch by the first restraining means is released. For this reason, when the slide door is moved in the opening direction, the latch rotates to the first rotation position when the restriction by the latch return member is removed, and moves to the position in contact with the stopper. When the slide door is further moved in the opening direction in this state, the arm portion of the latch abuts on the intermediate striker, and further movement of the slide door in the opening direction is prohibited. This is the intermediate lock state. To release the intermediate lock state, the slide door may be moved in the closing direction and the window glass may be raised to a predetermined position or higher.

In the present invention, the mechanism for engaging the intermediate striker and the full-open striker with one latch has an intermediate stopper function and a full-open stopper function, so that space can be saved. Further, since the switching of the operation start / stop of the intermediate stopper function is performed using the latch that instantaneously moves to the first rotation position, an incomplete state does not occur during the switching. Further, since the latch is provided with a fully-open stopper function by engaging the fully-open striker, the operating force of the slide door can be reduced, and the slide door can be held at a fully-open position with a strong force.

According to a second aspect of the present invention, the invention of the first aspect is realized with a simple configuration, and the step formed on the outer peripheral portion of the latch is rotatably disposed, and the neutral rotation is performed.

First, the intermediate stopper function will be described. On the base plate 61, the intermediate striker 67
Is rotatably supported by a pin 72 so as to be rotatable. The latch 71 is urged in the direction of arrow D by a torsion spring 73 as first urging means.

The latch 71 has a rotation center axis (pin 7).
The movement trajectory of 2) is arranged at a position where it passes between the intermediate striker 67 and the fully-opened striker 69 shifted in the width direction of the slide door. , And a lock groove 71b that can be engaged with and disengaged from the fully opened striker 69. Then, the arm portion 71a does not come into contact with the intermediate striker 67, and the lock groove portion 71b can be engaged with the fully opened striker 69 at a neutral rotation position (see FIG. 5), and the arm portion 71a rotates from the neutral rotation position to the intermediate striker 67 side. The first rotational position (see FIG. 4) at which the intermediate striker 67 can be brought into contact with the intermediate striker 67, and the lock groove 71b is pushed from the neutral rotational position by the fully opened striker 69 engaged with the lock groove 71b.
The second rotation position (see FIG. 6) in which the lock groove 71b rotates to the side and the lock groove 71b and the fully-open striker 69 mesh with each other can be taken.

When the slide 71 is at the first rotation position when the slide door returns to the fully closed position, the back surface is pushed up by the latch return member 68 and pushed back to the neutral rotation position. A stopper 75 is provided on the base plate 61 to prevent the arm 71a of the latch 71 from rotating beyond the first rotation position toward the intermediate striker 67 (clockwise in FIGS. 1 and 2). In the state shown in FIGS. 2 and 4, the latch 71 is pressed against the stopper 75 by the torsion spring 73 as the first urging means.

The first pole 81 is connected to the base plate 61.
It is rotatably supported by a pin 82 above. The pawl 81 is urged by a torsion spring 83 as a second urging means in a direction in which the first pawl 81 slides on the outer peripheral portion of the latch 71 (the direction of arrow E). A step 71c is formed on the outer periphery of the latch 71, and the first pawl 81 is connected to the latch 71 that has reached the neutral rotation position.
Abuts on the stepped portion 71c to restrict the latch 71 from returning from the neutral rotation position to the first rotation position.

A cable 101 driven by an intermediate stopper control mechanism is connected to an end of the first pole 81 opposite to the latch 71. When the cable 101 is pulled, the first pole 81 rotates and the first pole 81 rotates.
Is disengaged from the step 71c of the latch 71, and the latch 71 is released from being restrained by the first pole 81.

Therefore, the first pole 81 and the latch 71
And the torsion spring 83 as the second urging means engage with the latch 71 reaching the neutral rotation position from the first rotation position, and the latch 71 is moved to the first rotation position.
The first restricting means for restricting the return to the rotational position direction and releasing the restriction when exerting the intermediate stopper function.

The second pole 91 is rotatably supported on the base plate 61 by a pin 92.
The pawl 91 is urged by a torsion spring 93 as a third urging means in the direction of engagement with the protruding wall 71d of the latch 71 (the direction of arrow F). This protruding wall 7
Reference numeral 1d denotes a portion on the latch 71 which is pressed by the fully opened striker 69 when the latch 71 moves from the neutral rotation position to the second rotation position, and also forms a wall of the lock groove 71b. . The second pawl 91 contacts the protruding wall portion 71d of the latch 71 that has reached the second rotation position, and restricts the latch 71 from returning to the neutral rotation position.

A cable 102 driven by an inner handle or an outer handle of an automobile is connected to an end of the second pole 91 opposite to the latch 71. When the cable 102 is pulled in the state of FIG. 6, the second pawl 91 rotates, the engagement between the second pawl 91 and the protruding wall portion 71d of the latch 71 is released, and the latch 71 It is released from the restraint by the pole 91 and returns to the neutral rotation position.

Therefore, the second pole 91 and the latch 71
And the torsion spring 93 as the third urging means engages with the latch 71 that has reached the second rotation position from the neutral rotation position, and the latch 71 moves in the neutral rotation position direction. When the full-open stopper function is stopped, a second restraining means for releasing the restriction is constituted.

The stopper 105 provided on the base plate 61 regulates the amount of rotation of the first pole 81 in the restraint releasing direction.
The stop position is determined. (Intermediate Stopper Function) First, when the slide door is in the fully closed position and the window glass is in the fully closed state, the latch 71 is rotated to a position where it cannot contact the intermediate striker 67 as shown in FIG. The rotation in the direction of arrow D is restricted by the engagement between the step 71c and the first pole 81.

Here, a motor (not shown) is driven in a direction of lowering the window glass in a fully closed state. When the window glass is lowered to a position near a predetermined position, the first pole 81 is pulled by the cable 101 (inner wire). It rotates and the engagement with the latch 71 is released.

For this reason, the back surface of the latch 71 (the lower surface of the arm portion 71a) presses the latch return member 68 by the urging force of the torsion spring 73 as the first urging means. When there is no more, the rotation is made to a position where it comes into contact with the stopper 75, and the first rotation position where it can come into contact with the intermediate striker 67 (see FIGS. 2 and 4).
It is in a state where it can move to.

When the slide door in this state is moved in the opening direction, the latch 71 moves away while sliding on the latch return member 68 as the slide door moves, and when the restriction is removed, the latch 71 rotates to the position where it comes into contact with the stopper 75. (See FIGS. 2 and 4). When the slide door is further moved in the opening direction, the latch 71 comes into contact with the intermediate striker 67, and further movement of the slide door is prohibited (intermediate lock state).

To release the intermediate lock state, the slide door is moved in the closing direction, returned to the position shown in FIG. 1, and the window glass is raised from a predetermined position. By this return operation, the back surface of the latch 71 is pushed by the latch return member 68 provided on the vehicle body side, and the latch 71
, And again engages with the first pawl 81 to release the intermediate lock state. (Fully-open stopper function) When the window glass is not lowered to a predetermined position, the latch 71 is in a neutral rotation position where it can be engaged with the fully-open striker 69 (see FIGS. 1 and 5).
And the slide door is movable to a fully open position.
Then, when the slide door is moved in the direction of the fully open position, the protruding wall portion 71d of the latch 71 comes into contact with the fully open striker 69, is pushed by the fully open striker 69, and rotates in the direction opposite to the arrow D.

At the time of the fully opening operation, the latch 71 continues to rotate while pushing the second pawl 91 against the urging force of the torsion spring 93 even if the rotating end abuts on the second pawl 91. As a result, the rotating end of the latch 71 rides over the second pole 91, and a state in which the second pole 91 has stopped retreating (state shown in FIG. 6). This state is a fully open lock state in which the lock groove 71b and the fully open striker 69 are engaged with each other, and the rotation of the latch 71 in the direction of arrow D is prohibited.

To release the fully open lock state, the inside handle or the outside handle for opening and closing the slide door is operated. Then, the cable 102 is pulled, and the second
The engagement between the pawl 91 and the latch 71 is released, the latch 71 can rotate in the direction of arrow D, and the fully open locked state is released. For this reason, the slide door can be moved in the closing direction.

In the present embodiment, the mechanism for engaging the intermediate striker 67 and the fully-open striker 69 with one latch 71 has an intermediate stopper function and a fully-open stopper function. Space can be achieved.

Further, since the operation of the intermediate stopper function is switched between start and stop by using the latch 71 which instantaneously moves to the first rotation position, the switching is promptly performed, and a state in which the switching is incomplete is performed. Absent. Therefore, compared to the conventional slide door in which the switching is incomplete, no noise is generated, the durability of the parts is improved, and the operation force for moving the slide door does not change.

Further, since the fully open striker 69 is engaged with the latch 71 to provide a fully open stopper function, the operation force of the slide door can be reduced, and the slide door can be held at the fully open position with a strong force.

The present invention is not limited to the above embodiment. For example, the first and second pawls 81 and 91 in the present embodiment restrain the latch 71 by pressing the latch 71. However, as long as the latch 71 can be restrained, For example, what is generally called a hook may be used as the first and second poles 81 and 91.

[0051]

As described above, according to the first aspect of the present invention, the mechanism for engaging the intermediate striker and the fully opened striker with one latch has the intermediate stopper function and the fully opened stopper function. Space saving can be achieved.
Further, since the switching of the operation start / stop of the intermediate stopper function is performed using the latch that instantaneously moves to the first rotation position, an incomplete state does not occur during the switching. Further, since the latch is provided with a fully-open stopper function by engaging the fully-open striker, the operating force of the slide door can be reduced, and the slide door can be held at a fully-open position with a strong force.

According to the second aspect of the present invention, the intermediate stopper mechanism according to the first aspect can be realized with a simple configuration.
