2. Description of the Related Art When mounting a windshield of an automobile on a window frame of an automobile, a wind molding mainly made of plastic is provided with a glass engaging groove consisting of an upper jaw and a lower jaw in the longitudinal direction. Since this wind molding is mainly made of plastic, it has flexibility as a whole, and it has a predetermined length for a curved quadrangular glass shape with rounded corners such as a rear window of an automobile. The wind molding formed in a ring shape can be enclosed and mounted in the shape of the wind glass within the range of its flexibility.

However, in the case of a windshield such as a sunroof attached to the ceiling surface of a vehicle body of an automobile, for example, unlike such a rear windshield, a quadrilateral glass having angular corners that are not continuous in a curve is used. To be done. When such an angular wind glass is attached to a window frame by using the above-described synthetic resin-based window molding, it is possible to treat the window glass within the flexibility range of one molding as described above. difficult. Therefore, a molding side corresponding to the side edge of the windshield is created and assembled and attached using a joint piece or the like.

That is, FIG. 5 shows an example of this conventional mounting example, which has a length corresponding to each of the edges of a window glass G1 having a substantially rectangular parallelepiped shape having four edges F1, F2, F3 and F4. Molding pieces 51, 52, 5
3, 54 are manufactured, the molding pieces are attached to the edges of the window glass G1, and the corner joint pieces P1, P2, P are formed at the corners.
3, P4 is to integrally connect the whole.

In the above example, the four molding pieces are disassembled and assembled, so that the work is complicated. Therefore, as shown in FIG. 6, the molding pieces 61, 62, 63 having the lengths corresponding to the three edges of the window glass G2 having the four edges are connected to the connecting members 64, 6 respectively.
5 and the like to form a U-shaped molding member 60 in advance, attach the molding member 60 to the corresponding edge of the window glass G2, and correspond to the remaining other glass edge F5 and to the corner joint pieces at both ends. A molding piece 66 provided with 67 and 68 is prepared, and these are integrally assembled and mounted.

As can be understood from the above-mentioned conventional example, it is almost impossible to use a molding which is formed in a continuous surrounding shape in advance for a quadrilateral glass having angular corners which are not curved and continuous. It was possible.

[0007]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above circumstances, and is directed to a quadrilateral glass having angular corners that are not curved and continuous,
The present invention proposes a novel wind molding structure for an automobile, which makes it possible to use a wind molding formed in a continuous surrounding shape in advance, thereby promoting rationalization and efficiency of assembly work.

[0008]

That is, the present invention is
A glass molding groove having a glass upper jaw piece and a jaw lower jaw piece that are fastened to the edge of the glass, and a wind molding consisting of four sides wrapped around the periphery of the glass having four curved edges that are not continuous, The wind molding is integrally formed in a quadrangular shape surrounding the outer shape of the glass, and the glass molding is formed in the vicinity of the corners of two adjacent molding sides forming one corner of the quadrilateral. The present invention relates to the structure of a wind molding for an automobile, in which a tapered notch that increases toward the corner is formed in the lower jaw piece of the groove.

The wind molding 10 shown in FIG.
Is used for a roof window of an automobile and is for wrapping a peripheral edge of a glass G having four edges E1, E2, E3, E4 which are not curved in a continuous manner. It consists of four sides 11, 12, 13, and 14 that surround it.

Each side 1 of this wind molding 10
As can be understood from the cross-sectional view of FIG. 4, 1, 12, 13, and 14 are composed of a molding body 20 having the same structure. That is, the molding body 20 has, in the longitudinal direction thereof, a glass engaging groove 21 composed of an upper jaw piece 22 and a lower jaw piece 23 that engage with the edge of the glass G. The upper surface 22A of the upper jaw piece 22 constitutes a design surface of the wind molding 10. Reference numeral 29 is a fin piece that comes into contact with the vehicle body panel of the automobile.

The molding body 20 is molded by a known means such as an extrusion molding method, and four molding sides 11, 1 having a predetermined length are formed corresponding to the respective edges of the glass G.
After being cut into 2, 13, and 14, they are integrally formed into a frame shape (so-called frame shape) that surrounds the outer circumference of the glass G by heat welding or adhesion. Reference numeral 15 in FIG. 1 represents a heat-welded portion. In addition, in this embodiment, the wind molding 10 is formed in a rectangular shape having a size of 500 mm × 700 mm.

Then, as shown in FIG. 1, four molding sides 11, 12 forming a frame-shaped wind molding 10 surrounding the outer circumference of the glass G are formed.
Of the two adjacent sides forming one corner C among the three and fourteen, in the vicinity of the corner C of the molding sides 13 and 14 in this case, the lower jaw of the glass engaging groove 21 of the molding body 20 forming them. The cutout 25 on the piece 23,
26 are provided.

The notch portions 25 and 26 of the lower jaw piece 23 extend from the corner portions C of the molding sides 13 and 14 to the corner portions C of the molding sides 13 and 14, respectively.
It has a taper shape that gradually increases toward.
In the embodiment, the lengths of the notches 25 and 26 are provided within a range of about 100 mm from the corner C of each molding side 13 and 14. Further, the cut depths of the cutouts 25 and 26 may be determined according to the convenience at the time of attaching glass described later, but the final cut depth at the corner C is the lower jaw piece 2.
It can be the root of 3.

The notches 25 and 26 and the sides of the molding body 20 having the same cross section are integrally formed in a frame shape, and then a predetermined position of the lower jaw piece 23 is cut and provided by a press die or a cutter. Preferred, but not limited to. The cutouts 25, 26
Is provided on the back surface of the wind molding 10, that is, on the non-designed surface, so there is no problem in appearance.

2 and 3 show a state in which the wind molding 10 of the present invention is attached to the glass G on the back side thereof. As shown in FIG. 2, each edge of the glass G is wrapped in the glass engaging groove 21 of the molding 10 from the corners other than the corner C where the cutouts 25 and 26 are provided in the frame-shaped wind molding 10. To be done.

Next, the molding sides 13 and 14 near the last remaining corner C are wrapped around the corresponding glass corner GC. At this time, the molding side 1 near the corner C
Since the lower jaw pieces 3, 14 are formed with tapered notches 25, 26 that increase toward the corner C, the lower jaw pieces 23, 14 of each piece 13, 14 are formed as shown in FIG. 23
Is gradually covered from the vicinity of the corner toward the corner C in the direction of the broken arrow b while turning to the front side as indicated by the solid arrow a in the figure. In this structure, since the cutting depth of the lower jaw piece of the molding at the glass corner portion GC, which is the most difficult to insert into the glass mounting groove, is configured to be the largest, the mounting can be easily performed.
