Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile door structure, and more particularly to a launch channel that fits into a recessed portion of a door sash and holds a window glass.

Conventionally, door structures for automobiles have been disclosed, for example, in Japanese Utility Model Application Publication No. 57-37612, etc.
A launch channel having a substantially U-shaped cross section is fitted into the recessed portion of the door sash, and the ends of both side walls of the launch channel are each extended toward the center of the bottom wall of the launch channel, and both extensions A device is known in which the peripheral edge of a window glass is slidably held therein.

By the way, in the above-mentioned conventional type, since the window glass is held in the center of the launch channel, that is, on the center line of the recessed part of the door sash, a large step is created between the outer surface of the door sash and the outer surface of the window glass, which increases air resistance and There were problems in that wind noise increased and the appearance also deteriorated.

The present invention has been made in view of this point, and by improving the shape of the launch channel so that the window glass moves from the center of the launch channel to the outside of the vehicle when the window glass is fully closed, The object of this invention is to reduce the level difference between the outer surfaces of the door frame and the window glass to create a flat surface, thereby reducing air resistance and wind noise, and improving the external appearance.

For this purpose, the configuration of the present invention is such that a launch channel with a substantially U-shaped cross section that holds the window glass is fitted into the recessed part of the door sash, and the outer side wall of the launch channel is shaped like a substantially flat plate. The tip of the interior side wall is extended toward the vehicle exterior side of the launch channel bottom wall, and the extension part is extended toward the vehicle interior side of at least one of the vehicle interior side wall of the launch channel opposite to the extension part. When the window glass is fully closed, the restriction part is sandwiched between the interior side wall of the launch channel and the extension, and prevents the windshield from moving toward the vehicle exterior part of the launch channel. The door frame is configured to be displaced, thereby making the door sash and the window glass almost a flat surface when the window glass is fully closed.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

1 to 3 show an automobile door structure according to an embodiment of the present invention, in which 1 is a door panel, 2 is a door sash constituting a window frame above the door panel 1, and the outer circumferential surface of the door sash 2 A weather strip mounting portion 2a is formed on the side to which a weather strip (not shown) is attached, while a recessed portion 2b is formed on the inner circumferential side, and the peripheral edge of the window glass 3 is slid into the recessed portion 2b. A launch channel 4 having a substantially U-shaped cross section that can be freely held is fitted.

The tips of the interior and exterior side walls 4a and 4b of the launch channel 4 at the front and rear sides of the door sash 2 are located at the center of the bottom wall 4c of the launch channel 4, respectively, as shown in FIG. It extends towards the windshield 3.
During full closing, the window glass 3 is held between the extensions 5, 5 at the center of the launch channel 4, that is, on the center line of the recessed portion 2b of the door sash 2.

On the other hand, at the upper side of the door sash 2, as shown in FIG. 3, the vehicle outer side wall 4b of the launch channel 4 has a substantially flat plate shape, and the tip of the vehicle interior side wall 4a is connected to the bottom wall of the launch channel 4. 4c toward the outside of the vehicle. On the inner surface of the extension part 6 and on the interior side wall 4a of the launch channel 4 facing the extension part 6, regulating parts 7 and 8 for regulating the movement of the extension part 6 toward the interior of the vehicle interior are arranged close to each other and facing each other. When the window glass 3 is fully closed, the above-mentioned restricting parts 7 and 8 are sandwiched between the cabin inner side wall 4a of the launch channel 4 and the extension part 6 in a state where they are in contact with each other. window glass 3
The launch channel 4 is configured to be displaced toward the vehicle outer side portion of the launch channel 4.

The shape of the outer side wall of the launch channel 4 at the front and rear sides of the door sash 2 may be substantially flat, similar to the shape at the upper side.

Therefore, in the embodiment described above, when the window glass 3 is fully closed, the side edge of the window glass 3 touches the side of the door sash 2, especially both extensions 5 of the launch channel 4 on the rear side. 5, and as a result, the window glass 3 moves up and down on the center line of the recessed portion 2b of the door sash 2.

On the other hand, when the window glass 3 is fully closed, with the upper end of the window glass 3 being clamped by the launch channel 4 on the upper side of the door sash 2, the upper end of the window glass 3 is initially held at the passenger compartment side wall 4a of the launch channel 4 at the tip. The extension part 6 extends from the bottom wall 4c toward the outside of the vehicle, but the extension part 6
Since the movement toward the inside of the vehicle is restricted by the contact between the restriction parts 7 and 8, the window glass 3
As it rises, it is displaced to the outer side of the launch channel 4 by the extension 6, and finally the upper end of the window glass 3 is held between the outer side wall 4b of the launch channel 4 and the tip of the extension 6. Ru. As a result, while ensuring the sealing performance of the window glass 3, the difference in level between the outer surface of the door sash 2 and the outer surface of the window glass 3 is reduced, making it possible to form both into a flat surface, thereby reducing air resistance and wind deflection. Not only can noise be reduced, but also the appearance can be improved.

In the embodiment described above, the restriction parts 7 and 8 for restricting the movement of the extension part 6 toward the passenger compartment side are integrally formed with the extension part 6 and the passenger compartment side side wall 4a of the launch channel 4 facing the extension part 6. However, in the present invention, as shown in FIG. 4, a separate restriction portion 9 may be provided between the extension portion 6 and the interior side wall 4a, and similar effects can be obtained. (Note that in FIG. 4, the same parts as in FIG. 3 are given the same reference numerals and their explanations are omitted.)
Further, the restriction portions 7 and 8 may be formed only on either the extension portion 6 or the cabin side side wall 4a of the launch channel 4 facing the extension portion 6.

Furthermore, by providing wedge-shaped regulating portions (not shown) in the lower part of the window glass and the inner panel of the door, it is possible to displace the entire window glass to the outside of the vehicle.

As explained above, according to the present invention, the tip of the side wall of the launch channel on the inside side of the vehicle is extended toward the outside of the vehicle of the bottom wall of the launch channel, and the extended portion allows the window glass to be fully closed. Since the windshield is sometimes moved to the outer side of the launch channel, it is possible to reduce the surface level difference between the door sash and the windshield and create a flat surface, thereby reducing air resistance and wind deflection. It is possible to reduce noise and improve the appearance.
