Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for opening and closing a window glass installed in an automobile window.

In this type of automobile power window device, the motor rotates forward or reverse to open and close the windshield only while the switch for opening and closing the windshield is switched to the closing side or the opening side. Therefore, if you want to open or close the window glass to the desired opening degree, keep switching the switch to the closed side or the open side until the window glass reaches the desired opening degree. At that point, the switch must be released, and it takes a lot of time to operate the switch when the windshield is opened or closed 80% to 90% of the way. This requires visual inspection, and when the driver opens or closes the window glass while driving, there is a drawback that driving safety is temporarily reduced.

Therefore, the present invention has been made to eliminate the above-mentioned drawbacks, and by instantly setting the switch to a state corresponding to the desired opening degree of the window glass, the window glass can be adjusted to follow the opening position until it reaches the set opening degree. An object of the present invention is to provide a power window device for an automobile, which can be opened and closed in different directions, and can maintain driving safety even when a driver opens and closes a window glass while driving.

The motor 6 is placed opposite the intermediate contact 22 of the contact element 18.
is driven forward. Therefore, the normal rotation of the motor 6 causes the regulator arm 8 to swing in the opposite direction to the above, thereby raising the window glass 4 and raising the first contact element 18. Then, when the window glass 4 is raised to the highest end and becomes fully closed, the intermediate contact 22 of the first contact element 18 is exactly located at the blocking position 2 of the second contact element 20 as shown by the solid line in FIG. As a result, the normal rotation of the motor 6 is stopped, and the rising of the window glass 4 and the first contact element 18 is also stopped, and the window glass 4 is maintained in the fully closed state shown in FIG. . Next, if you want to open the window glass 4 by, for example, one third, move the knob 21 one third from the top of the length of the long operating hole 16.

3, and when it is not opened by more than one-third, the knob 21 is moved downward, so it becomes a reversing contact 25), which contacts the intermediate contact 22 to rotate the motor 6 forward or reverse, thereby opening the window glass 4 and The first contact element 18 is raised or lowered. When the window glass 4 is raised and lowered to a position where it is opened by one-third, the intermediate contact 22 of the first contact element 18 comes into contact with the cutoff position 24 of the second contact element 20, and the rotation of the motor 6 is stopped. , the lifting and lowering of the window glass 4 and the first contact element 18 is also stopped, and the window glass 4
is held open by one-third. As described above, by moving the second contact element 20 by the amount of movement corresponding to the desired opening degree of the window glass 4 using the knob 21, the window glass 4 follows the desired opening degree corresponding to the movement amount. It can be opened and closed automatically. Therefore, the movement of the second contact element 20 by the knob 21 can be instantaneously performed with a one-touch operation and then immediately released, and the opening/closing operation of the window glass 4 can be easily performed in a short time.

A diversion contact is provided on the other side, a reversal contact is provided on the other side, and an intermediate contact is provided on the other side, and with the intermediate contact facing the cutoff position, the second contact element is moved by a desired amount relative to the first contact element. When moved, the intermediate contact comes out of the blocking position and comes into contact with the forward rotation contact or the reverse rotation contact, thereby causing the motor to rotate forward or reverse, opening and closing the window glass until the intermediate contact comes into contact with the blocking position again. Therefore, when it is desired to open or close the window glass to a desired degree of opening, the second contact element of the switch is moved relative to the first contact element by an amount corresponding to the desired degree of opening of the window glass. Therefore, the window glass can be automatically opened and closed to a desired degree of opening corresponding to the amount of movement of the window glass, and the opening and closing operations of the window glass can be easily performed.

Furthermore, since the configuration is as described above, when the driver performs the above-mentioned opening/closing operation of the window glass while driving, the second contact element of the switch is connected to the first contact element to open the window glass as desired. By simply momentarily moving an amount corresponding to the degree of opening, the windshield can be moved and stopped by the amount corresponding to the amount of opening.This allows the driver to open and close the windshield while driving. This has the effect of allowing the driver to concentrate on driving even when driving, thereby maintaining driving safety.
