BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide door that is attached to a side portion of a vehicle so as to be openable and closable, and relates to a slide door having an intermediate stopper mechanism that regulates a movement of the slide door in the opening direction within a certain range. .

[0002]

2. Description of the Related Art As shown in FIG. 17, a window glass 1 is provided on a sliding door 3 of a vehicle or the like so that it can be moved up and down. Therefore, when the sliding door 3 is opened with the window glass 1 being lowered and an object is inserted in the window of the sliding door 3, the object is sandwiched between the window frame 7 of the sliding door 3 and the pillar 9. May be damaged.

Therefore, in order to avoid this situation, it is proposed that an intermediate stopper mechanism is provided to stop the sliding door which is moving in the opening direction during opening when the window glass 1 is lowered below a predetermined position. Has been done.

FIG. 18 shows an example of this sliding door.
There is something like. First, the intermediate stopper control mechanism 11 pulls in the cable (inner cable) 13 according to the lowered amount while the window glass 1 is lowered by a predetermined amount L (for example, 150 mm) from the fully closed state. On the other hand, when the movement stroke of the cable 13 reaches the set value, the pulling-in of the cable 13 is stopped. However, even in this situation, the windshield 1 can descend.

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 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
The configuration of No. 1 will be described in detail with reference to FIG. A base plate 31 is fixed to the inner panel of the slide door 3, and a pin 33 is 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, the one end 39a is hooked by the first lever 35, and the other end 39b is wound by the second lever 37.
Are hung on.

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

Next, the structure of the intermediate stopper mechanism 15 is shown in FIG.
It will be described using 0. A base plate 21 is fixed to the lower portion of the inner panel of the slide door 3, and a lever 22 is rotatably attached to the base plate 21. The lever 22 is connected to the cable 13 and
It is biased in the direction of arrow I by a biasing means (not shown). At the tip of the lever 22, the elastic roller 2 is attached.
4 are provided. On the other hand, on the vehicle body 26 side, the roller 2
4 is formed so as to be able to abut.

In the conventional sliding door 3, when the window glass 1 in the fully closed state is lowered by using the window regulator 16, the first lever 35 also moves counterclockwise in FIG. 19 as the window glass 1 is lowered. Rotate to. The second lever 37 is also the spiral spring 3
Since it is connected to the first lever 35 via 9, it rotates counterclockwise and pulls in the cable 13.

When the moving stroke of the cable 13 reaches the set value, the rotation of the second lever 37 is restricted,
It becomes impossible to rotate following the first lever 35. However, even in this situation, the spiral spring 39
Elastically deforms so that the first lever 3
Only 5 can rotate counterclockwise, and the window glass 1 can descend.

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 the cable 13 by a predetermined amount, and the lever 2 is pulled.
2 rotates against the biasing force of the biasing means (not shown), and moves from the two-dot chain line position in FIG. 20 to the solid line position.

When the slide door 3 is moved in the opening direction in this state, the roller 24 comes into contact with the step portion 28 on the vehicle body side, stops at that position, and the slide door 3 cannot be opened any further.

[0014]

In the sliding door 3 having the intermediate stopper mechanism 15, even if the window glass 1 is lowered and an object is inserted in the window of the sliding door 3, in this situation, the sliding door 3 Since there is always a space between the window frame 7 of 3 and the pillar 9, it is possible to avoid a situation in which an object inserted into the window is caught. However, it has the following drawbacks.

When the window glass 1 is lowered from the fully closed state, before the window glass 1 reaches the predetermined amount L, the intermediate stopper control mechanism 11 gradually pulls the cable 13, so that the lever 22 also gradually rotates. Therefore, when the sliding door 3 is strongly pulled in the opening direction while the descent of the window glass 1 is slightly smaller than the predetermined amount L, the roller 24
After coming into contact with the step portion 28, it goes over the step portion 28 and advances, and the slide door 3 moves to the fully open position.

That is, during the switching operation of the intermediate stopper mechanism 15, the roller 24 is in a halfway state for a long time,
In this halfway state, the roller 24 goes over the step portion 28 and advances. When the sliding door 3 slides in this state, a large load is applied to the roller 24, the lever 22, the base plate 21 and the like, and not only the durability of these parts deteriorates but also abnormal noise is generated and the sliding door 3 The opening operation force of is increased, and the operation feeling becomes worse.

Further, when the window glass 1 is lowered by a predetermined amount L or more, the intermediate stopper mechanism 15 is required to stop the slide door 3 by reliably contacting the roller 24 of the roller 24 with the step portion 28 on the vehicle body side. However, since the roller 24 is in a halfway state in a wide range, it is absolutely necessary to adjust the mounting state of the base plate 21 by trial and error in order to obtain a reliable operation.

It is an object of the present invention to provide a slide door which eliminates the above-mentioned drawbacks of the conventional slide door. That is, an object of the present invention is to provide a slide door that does not cause a halfway state when switching the intermediate stopper mechanism.

As a result, the back surface of the pole 71 is pushed by the pole push-back member 68 provided on the vehicle body side, the pole 71 rotates in the direction opposite to the arrow D, and the first hook 73 again causes the pole 7 to move.
1 and the intermediate lock state is released.

(Operation of the fully open stopper mechanism) FIGS. 1 and 2
The operation of the full-open stopper mechanism 65 will be described with reference to. When the slide door is in the non-fully opened state, the latch 81 is at the position (the position shown in FIGS. 1 and 2) where the latch 81 can be engaged with the fully open striker 69 by the urging force of the third urging means.

When the slide door moves in the fully open direction, the fully open striker 69 engages with the engaging groove 81a of the latch 81, and further the latch 81 rotates clockwise. Latch 8
When 1 rotates, the second hook 83 engages with the latch 81 by the biasing force of the fourth biasing means, and the arrow F of the latch 81
The rotation in the direction is prohibited, and the latch 81 is in the fully open locked state as shown by the chain double-dashed line in FIG.

To release the fully open lock state, the inside handle or the outside handle is operated. Then, the cable 85 is pulled in, the engagement of the second hook 83 with the latch 81 is released, the latch 81 becomes rotatable in the direction of the arrow F, and the fully open locked state is released. Therefore, the slide door can be moved in the closing direction.

In the slide door of the present embodiment, the intermediate stopper mechanism 63 is composed of the pole 71 and the first hook 73, so that the switching is performed quickly and there is no halfway state in the switching. Therefore, compared to the conventional slide door that has a halfway switching, there is no abnormal noise,
The durability of the parts is also improved, and the operating force to move the sliding door does not change. Further, when the intermediate stopper mechanism 63 is attached, it is not necessary to make a troublesome adjustment of the attached state, and the attaching work is facilitated.

Further, the stopper 77 and the pole 71 are brought into contact with each other by a flat surface, and the inclination of the contact surface is selected so as to include the rotation center axis of the pole 71 on the extension surface. Forces act only vertically on the surfaces, and the contact portion can withstand a high load. Therefore, it is possible to avoid damage to this portion due to impact. Further, the contact between the pole pushing-back member 68 and the pole 71 is not a collision between metals, and a high collision sound peculiar to metals is eliminated.
Further, before the stopper 77 and the pole 71 come into contact with each other, the cushioning member 72 comes into contact with the convex portion 71m of the pole 71, and after the cushioning member 72 is elastically deformed, the stopper 77 and the pole 7 are brought together.
Since 1 and 1 contact, the impact at the time of collision between the stopper 77 and the pole 71 can be softened and the collision noise can be reduced.

The present invention is not limited to the above embodiments. For example, the full-open stopper mechanism 6
5, the configurations of the intermediate stopper control mechanism 151, the window regulator and the like are not limited to those of the above-mentioned embodiment.

[0077]

As described above, according to the invention described in claims 1 to 4, the switching of the intermediate stopper mechanism is promptly performed, and the halfway state does not occur.

In addition, according to the first aspect of the invention, when the slide door is attached to the vehicle body, even if the relative position between the support plate and the roller arm in the thickness direction of the slide door is adjusted, it is provided on the vehicle body side. Since the positional relationship between the guide rail and the base plate does not change, and the distance between the intermediate stopper and the pole that abuts against it in the thickness direction of the slide door does not change, the intermediate position after the relative position adjustment between the support plate and the roller arm is adjusted. The position adjustment of the stopper mechanism becomes unnecessary.

According to the second aspect of the present invention, the stopper and the pole are brought into contact with each other by a flat surface, and the contact surface includes the rotation center axis of the pole on the extension surface.
The contact part can withstand a high load. Therefore, it is possible to avoid damage to this portion due to impact.

According to the third aspect of the present invention, the contact between the pole pushing back member and the pole is not a collision between metals, and a high collision noise peculiar to metals is eliminated. According to the invention of claim 4, before the stopper and the pole come into contact with each other,
Since the cushioning member abuts on the pole, the impact at the time of collision between the stopper and the pole can be softened and the collision noise can be reduced.
