[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a slide door that can be opened and closed on a side portion of a vehicle, etc., and a window regulator that lifts and lowers a window glass by a rotationally driven lift arm, and movement of the slide door in the middle of opening within a certain range. A slide door provided with a controllable intermediate stopper mechanism and an intermediate stopper control mechanism for restricting the movement of the slide door in the opening direction within a certain range when the opening of the window glass exceeds a certain level.
About.
[0002]
[Prior art]
As shown in FIG. 7, 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.
[0003]
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. .
[0004]
An example of this sliding door is shown in FIG.
First, the intermediate stopper control mechanism 11 pulls in the cable (inner cable) 13 according to the amount of lowering 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 moving stroke of the cable 13 reaches the set value, the drawing of the cable 13 is stopped. However, even in this situation, the wind glass 1 can descend.
[0005]
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 X arm type window regulator 16 drives the window glass 1 in the vertical direction.
[0006]
Here, the configuration of the intermediate stopper control mechanism 11 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.
[0007]
The spiral spring 39 is wound around the pin 33, one end 39 a is hooked on the first lever 35, and the other end 39 b is hooked on the second lever 37.
[0008]
A roller 41 is provided at the rotating end of the first lever 35, and this roller 41 is engaged with a guide 17 provided at the lower part of the window glass 1 so as to be movable in the horizontal direction in the figure. . The cable 13 is connected to the second lever 37.
[0009]
Next, the configuration of the intermediate stopper mechanism 15 will be described with reference to FIG. A base plate 21 is fixed to the lower part 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 is urged in the direction of arrow I by urging means (not shown). An elastic roller 24 is provided at the tip of the lever 22. On the other hand, on the vehicle body 26 side, a step portion 28 that can contact the roller 24 is formed.
[0010]
In the conventional sliding door 3, when the fully closed window glass 1 is lowered using the window regulator 16, the first lever 35 also rotates counterclockwise in FIG. 9 as the window glass 1 is lowered. . Further, since the second lever 37 is also connected to the first lever 35 via the spiral spring 39, the second lever 37 rotates counterclockwise and pulls in the cable 13.
[0011]
When the moving stroke of the cable 13 reaches the set value, the rotation of the second lever 37 is restricted and the second lever 37 cannot rotate following the first lever 35. However, even in this situation, by elastically deforming the spiral spring 39 so as to reduce the diameter, only the first lever 35 can rotate counterclockwise, and the window glass 1 can be lowered.
[0012]
Accordingly, 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 22 rotates against the urging force of the urging means (not shown), It moves from the two-dot chain line position in FIG. 10 to the solid line position.
[0013]
When the slide 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 and stops at that position, and the slide door 3 cannot be opened any more. That is, in the sliding door 3, even if the window glass 1 is lowered and an object is inserted into the window of the sliding door 3, there is always a space between the window frame 7 and the pillar 9 of the sliding door 3. It is possible to avoid a situation where an object inserted into the window is caught.
[0014]
[Problems to be solved by the invention]
However, the intermediate stopper control mechanism 11 of the slide door 3 having the above-described configuration requires the first lever 35, the second lever 37, the spiral spring 39, and the like. .
[0015]
Further, the intermediate stopper control mechanism 11 takes up a large space because these parts are large.
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 having an intermediate stopper control mechanism that does not take up space at low cost.
[0016]

[0081]
Further, the third arm 313 is separated from the movement locus of the pin 331, and the fourth arm 314 is located on the movement locus of the pin 331.
To release the intermediate lock state, the slide door is moved in the closing direction, returned to the position shown in FIG. 2, and the window glass 113 is raised from a predetermined position. By this returning operation, the pin 331 of the driven gear 107 pushes the fourth arm 314, the entire lever 315 rotates in the opposite direction, and the second arm 312 gets over the convex portion 301b and sandwiches the convex portion 301b. Move to one side.
[0082]
At this time, the fourth arm 314 comes into contact with the first stopper 341 and further movement is prohibited.
By rotation of the lever 315, the cable 75 locked to the first arm 311 is returned, and the first hook 73 can be returned to the original position, and the pole push-back member 68 provided on the vehicle body side is connected to the back surface of the pole 71. Is pushed, the pole 71 rotates in the direction opposite to the arrow D, the first hook 73 engages with the pole 71 again, and the intermediate lock state is released.
[0083]
According to the above configuration, the intermediate stopper control mechanism 300 includes the lever 315 formed with the first, second, third, and fourth arms 311, 312, 313, and 314, and the first arm 311 of the lever 315. A cable 75 whose one end is locked and whose other end is locked to the intermediate stopper mechanism 63 is provided on the rotation trajectory of the second arm 312 of the lever 315 so that the second arm 312 can get over. Since the portion 301b and the pin 331 provided on the lift arm side and capable of pressing the third and fourth arms 313 and 314 are configured, a space is not required at a low cost.
[0084]
Further, by providing the first and second stoppers 341, 342, the third or fourth arm 313, 314 is pushed by the pin 331, the lever 315 rotates, and the second arm 312 becomes the convex portion 301b. When moving to one or the other side across the convex portion 301b, the fourth or third arm 314, 313 is prevented from passing over the movement path of the pin 331 when moving to one or the other side across the convex portion 301b. it can.
