Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for attaching the ends of a window panel, and more particularly to a structure for attaching the ends of a window panel in which folded portions that go around to the outer surface of a pillar are formed on both sides.

Traditionally, the front of an automobile has a flat front panel.
C window glass is installed (for example, in Showa 5
(November 2005, Nissan Motor Co., Ltd. Nirasan Laurel Maintenance Instructions C31) Recently, in order to improve the aerodynamic characteristics at both ends of the front window glass, as shown in Figure 1, front pillars have been It has been considered to use a front window glass G in which folded portions 2 extending around the outer surface of glass 1 are formed on both sides. For example, as shown in FIG.
The resin film 3 is sandwiched between the front pillars 1 and G2, and the parts are glued together to form a groove, and the part that should face the front pillar 1 is colored with the black resin film 3.

When installing such a front window glass G to the edge of a window opening at the front of the vehicle interior, for example, a window opening flange (on both sides of the window opening shown in FIG. As shown, the pillar outer panel la constituting the outer surface of the front pillar 1
) and the folded part 2 of the front window glass G
After applying adhesives Sl and S2 to the side surfaces of the pillar outer panel 1a to which the front window glass G is fixed,
While visually checking the lateral center of the left and right front pillars 1 and 1, move the front window glass G from the front of the vehicle (from above in Figure 2) to the front pillar L.
A conceivable method is to fit the front window glass G into the front pillar 1 or the like and adhesively fix the front window glass G to the front pillar 1 or the like. The bent portion 2 formed on the front window glass G is
2 is fixed to the side of the pillar outer panel la,
This prevents the glass from lifting up, ensuring the impact strength of the glass at the bent portion 2 and the watertightness of the end portion 5, and also ensuring that the glass is connected to the side window glass 8 with a smooth surface so that the appearance quality is not impaired. .

However, in such a mounting means, in order to fit the front window glass G to the left and right front pillars L by moving it in parallel from the front position of the vehicle body shown by the imaginary line in FIG. 2 in the direction of the arrow, the pillar outer panel la
Adhesive S2 applied to the side surface of the rear edge 5a of the folded portion 2
If you scrape it off or use adhesive S on the inside surface of the fold
2, the adhesive S2 may rub diagonally on the pillar outer panel 1a and peel off, or it may break when the front window glass G is pressed onto the front pillar 1 and fixed with adhesive. There is a risk that the adhesive S2 may flow out from the end portion 5 of the portion 2, and there is a problem that the adhesive strength of the folded portion 2 is not sufficiently ensured.

In FIG. 2, reference numeral 1b indicates a pillar inner panel, 7 a weather strip that seals the side window glass 8 and the vehicle interior, 6 a retainer to which the weather strip 7 is attached, 9 a screw for fixing the retainer 6, 10 is a molding, and 11 is a dumb rubber.

The present invention has been made focusing on the above problems,
The purpose is to provide a structure for attaching the edge of a window panel that can secure sufficient adhesive strength at the edge of the folded portion of the window panel. The gist of the present invention is to form folded parts on both sides of the window panel that go around the outer surface of the pillar.
In the edge mounting structure of a window panel in which the end of the folded part is fixed to the pillar with an adhesive, the gap formed by the end of the folded part and the pillar is filled with adhesive in the mounting leg part. This is due to the installation of weather strips.

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

In the embodiment shown in FIGS. 3 to 6, the weather strip 13, which is arranged close to the rear end of the windshield glass G, has a base 14 attached to the vehicle body, and extends integrally from the base 14. A weather strip 13 is provided on the lower surface of the base 14.
During molding, the core metal 27 is integrally embedded, and the mounting leg portion 16 fixed to the base portion 14 is formed to protrude. This mounting leg 16 is made of two rectangular thin spring steel plates tea and I.
Bb is bent into a substantially diamond-shaped cross section to form a cavity 28 inside which is filled with the adhesive S2, with openings 17 and 18a at the tip and upper and lower ends, respectively.

18b, and bent portions 19a and 19b are bendable and deformable. In addition, this mounting leg 16 is
A plurality of strips 13 are provided at regular intervals along the length of the strip 13 to ensure that the weather strip 13 is securely attached.

On the other hand, the dam rubber 20 adhesively fixed to the inner surface of the folded part 2 of the front window glass G has an upper dam part 21 that comes into contact with the pillar outer panel 1a to prevent the adhesive from flowing out.
It is composed of an auxiliary section 22 that extends in a direction perpendicular to the upper dam section 21 and is inserted into the space between the adjacent upper and lower mounting legs 16.16. A plurality of auxiliary neck portions 22 are formed to protrude along the longitudinal direction of the dam rubber 20 in correspondence with the mounting leg portions 1B, and as shown in FIG. When inserted, the mounting leg 1
6 is placed close to the upper and lower ends of the 6.

Therefore, when the front window glass G is adhesively fixed to the front window opening edge of the vehicle body, the dam rubber 20 is first arranged and fixed on the inner surface of the folded part 2 formed in the front window glass G, and then the front window The glass G is fitted into the front pillar 1 from the front of the vehicle body, and the periphery of the flat front part 4 is attached to the peripheral flange of the window opening (on both sides of the window opening, as shown in FIG. 5, the front surface of the pillar outer panel 1a) via instant adhesive S1. and fix it. Note that the adhesive Sl is applied to the vehicle body side or the front window glass G side.

Next, the inner cavity 28 of the mounting leg 18 formed protruding from the base 14 of the weather strip 13 is filled with adhesive S2 in advance, and the mounting leg 16 is attached to the folded part 2 of the windshield glass G and the pillar. The rear end of the bent portion 2 is press-fitted into the gap 23 formed between the folded portion 2 and the outer panel la.

At that time, the width between the bent portions 10a and 19b of the mounting leg portion 16 is
Since it is formed larger than the width of the gap 23,
As the mounting leg portion 16 is press-fitted, the bent portion 1 gradually bends.
11a.

19b is bent and extends within the gap 23. Therefore,
The adhesive S2 filled in the mounting leg 16 is gradually pushed out into the gap 23 from the tip opening 17 and the upper and lower openings 18a and 18b of the mounting leg 18. In this case, the adhesive S2 pushed out from the tip opening 17 of the mounting leg 16 is prevented from flowing forward by the upper dam 21 of the dam rubber 20, and is also pushed out from the upper and lower openings 18a, 18b of the mounting leg 16. As shown in FIG. 4, the adhesive S2 is prevented from flowing upwardly and downwardly by the auxiliary bases 22 disposed close to the upper and lower ends, and flows around to the front side.
The gap 23 formed by the dam rubber 20 on the rear end side of the folded part 2 is sufficiently filled in a sealed state, and the adhesive strength of the folded part 2 can be sufficiently ensured. Therefore, the end 5
It is possible to reliably prevent floating of the material and improve impact strength, watertightness, etc.

In addition, in the above embodiment, since the mounting leg portion 16 is formed to have a rhombic cross-section, the inclined surfaces at the front of the bent portions 19a and 18b can be used as guides during press-fitting, and when the press-fitting is completed, the right and left The bent portions L9a and 19b come into elastic contact with the inner surface of the bent portion 2 and the outer wall 1a, thereby ensuring the attachment of the weather strip 13. Therefore, in this embodiment, it is not necessary to fix the weather strip 13 with screws as in the conventional case, so that the number of work steps can be reduced accordingly. Furthermore, as shown in FIG. 7, the weather strip 25 disposed on the roof site rail 24 side of the upper side of the vehicle body is also provided with a mounting leg 16 similar to that described above. Use the drip mall 2
6 can be fixed to the vehicle body.

In the above embodiment, the mounting legs 18 are arranged in parallel at predetermined intervals, but they may be arranged in a continuous strip along the longitudinal direction of the weather strip 13. In this case, The auxiliary base 22 of Damra/<-20 is also formed to cover the upper and lower end openings of the mounting leg 1e in accordance with the shape thereof. Further, the front window panel is not limited to glass, and may of course be a resin panel.

As explained above, according to the window panel end attachment structure according to the present invention, the bent portions formed on both sides of the window panel can be reliably adhesively fixed to the vehicle body. Therefore, in addition to increasing the impact strength of the glass at the bend, sufficient watertightness is ensured, and there is no lifting of the bend, so the side window panel and the front window panel are connected on a smooth surface. As a result, a certain level of appearance quality can be maintained. Furthermore, the installation of the weather lamp becomes easier, and the workability of installing the front window nozzle can be improved.
