Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide door which can be opened and closed on a side portion of a vehicle or the like, and more particularly to a slide door having an intermediate stopper mechanism for restricting a movement of the slide door in the opening direction during opening 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 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 sandwiched between the window frame 7 of the sliding door 3 and the pillar 9. And may be damaged.

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

FIG. 18 shows an example of this sliding door.
There is something like that shown in First, while the window glass 1 is lowered by a predetermined amount L (for example, 150 mm) from the fully closed state, the intermediate stopper control mechanism 11 draws in the cable (inner cable) 13 according to the amount of the lowering. On the other hand, when the movement 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.

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 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 in detail 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.

In the conventional slide door 3, when the window glass 1 in the fully closed state is lowered using the window regulator 16, the first lever 35 also moves counterclockwise in FIG. To rotate. The second lever 37 is also provided by the spiral spring 3.
Since it is connected to the first lever 35 via the cable 9, it rotates counterclockwise and pulls 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
20 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.

[0014]

In the slide door 3 having the above-mentioned intermediate stopper mechanism 15, even if the window glass 1 is lowered and an object is inserted into the window of the slide door 3, in this situation, the slide door is not moved. Since there is always a space between the window frame 7 and the pillar 9 of the third embodiment, a situation where an object inserted into the window is caught can be avoided. However, it has the following disadvantages.

When the window glass 1 is lowered from the fully closed state, the intermediate stopper control mechanism 11 gradually pulls the cable 13 before the window glass 1 reaches the predetermined amount L, so that the lever 22 also rotates gradually. Therefore, when the sliding 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 rollers 24
After contacting the step portion 28, the slide door 3 advances over the step portion 28, 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 an incomplete state for a long time,
In this halfway state, the roller 24 moves over the step 28. When the slide 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, which not only reduces the durability of these parts, but also generates abnormal noise and the slide door 3 Opening operation force increases, and the operation feeling also deteriorates.

When the window glass 1 has dropped by a predetermined amount L or more, the intermediate stopper mechanism 15 needs to stop the slide door 3 with its roller 24 reliably hitting the step 28 on the vehicle body side. However, since the roller 24 is halfway 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 reliable operation.

An object of the present invention is to provide a slide door which has solved the above-mentioned drawbacks of the conventional slide door. That is, an object of the present invention is to provide a slide door in which a halfway state does not occur when switching the intermediate stopper mechanism.

5. The configurations of the intermediate stopper control mechanism 151, the window regulator and the like need not be limited to those of the above-described embodiment.

[0077]

As described above, according to the first to fourth aspects of the present invention, the switching of the intermediate stopper mechanism is promptly performed, and a halfway state does not occur.

In addition, according to the first aspect of the present invention, when the slide door is mounted on 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, the slide door is provided on the vehicle body. The relative position between the support plate and the roller arm after adjusting the relative position between the support plate and the roller arm does not change because the positional relationship between the guide rail and the base plate does not change, and the distance between the intermediate stopper and the abutting pole in the thickness direction of the slide door does not change. The position adjustment of the stopper mechanism becomes unnecessary.

According to the second aspect of the present invention, the contact between the stopper and the pole is made in a plane, and the contact surface includes the rotation center axis of the pole on the extension surface.
The contact portion can withstand high loads. Therefore, it is possible to prevent this portion from being damaged by impact.

According to the third aspect of the present invention, the contact between the pole push-back member and the pole is not a collision between metals, and a high collision sound peculiar to metal is eliminated. According to the invention described in claim 4, before the stopper and the pawl come into contact with each other,
Since the shock-absorbing member abuts on the pole, the impact at the time of collision between the stopper and the pole can be reduced, and the collision noise can be reduced.
