Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a laminated glass type automobile windshield, and particularly to a mounting structure suitable for a flash mount method.

In recent years, as an installation method for automobile windshields,
Glue the windshield to the window frame of the car body using a sealant so that the surface of the car body and the outside surface of the windshield are almost on the same level, and place a width in the gap between the outer peripheral edge of the windshield glass and the window frame of the car body. A flat-mounted automobile windshield installation structure in which a narrow molding is inserted is beginning to be adopted.
This flash mount system has the advantage of being excellent in appearance and reducing wind noise.

However, when laminated glass, which is made by bonding two glass plates with an interlayer film such as polyvinyl butyral, is used as a windshield, the interlayer film deteriorates due to moisture entering from the glass edge, causing bubbling and peeling at the glass periphery. Occur. Since such bubbling and peeling typically occur within 10 mm of the glass edge, conventional windshield mounting structures hide it with moldings and weather strips. However, in the above-mentioned flat mount method, the width of the molding is narrowed due to design requirements, so foaming and peeling occurring at the peripheral edge of the glass are noticeable, which is undesirable in terms of appearance. There is.

Therefore, the purpose of the present invention is to provide an automobile windshield glass that prevents foaming and peeling from occurring at the periphery of a laminated glass type windshield glass and makes it possible to apply a narrow molding in a flat mount method, etc. The purpose is to provide a mounting structure for

According to the present invention, a moisture-impermeable adhesive is applied to the outer peripheral end surface of the windshield glass, and the molding is adhered to the outer peripheral end surface of the windshield glass by the adhesive.

Therefore, the moisture-impermeable adhesive and molding prevent moisture from penetrating into the outer peripheral edge of the windshield, thereby preventing bubbling or peeling from occurring at the outer peripheral edge of the windshield.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the windshield 1 has two glass plates 2 and 3 made of a plastic interlayer film 4 for laminated glass such as a polyvinyl butyral film or a polyurethane film.
It is a laminated glass type bonded by. Then, the tempering glass 1 is attached to the window frame 7 of the automobile via a sealant 6 such as urethane resin or polysulfide resin so that the outer surface 5 of the automobile body and the outer surface of the windshield 1 are at approximately the same level.
is glued to. Further, a molding 8 is inserted into the gap between the outer peripheral end surface of the windshield 1 and the window frame 7 to seal the gap. Further, a dam rubber 9 is bonded to the inner periphery of the windshield 1 to seal the sealant 6 from the inside.

In the present invention, a moisture-impermeable adhesive 10 such as butyl rubber is applied to the outer peripheral end surface of the windshield 1, and the molding 8 is adhered to the outer periphery of the windshield 1 by this adhesive 10. . In this case, the windshield 1 is placed on the inner circumference of the molding 8.
Inwardly extending flanges 8a and 8b are formed with an interval that matches the thickness of the windshield 1, and the edge of the windshield 1 fits between the flanges 8a and 8b. As shown in FIG. 2, the interlayer film 4 of the windshield 1 is provided so as to be retracted slightly inward from the outer periphery of the glass plates 2, 3, and the interlayer film 4 of the windshield 1 is retracted slightly inward from the outer periphery of the glass plates 2, 3. The adhesive 10 has also entered the gap 11.

In the above configuration, moisture such as rainwater on the windshield 1 is prevented from penetrating into the outer peripheral end surface of the windshield 1 by the molding 8 and the moisture-impermeable adhesive 10. In particular, as shown in Figure 2,
If the adhesive has penetrated into the gap 11 between the glass plates 2 and 3, the effect of preventing moisture intrusion will be more reliable.
Therefore, the interlayer film 4 made of polyvinyl butyral or the like does not come into contact with moisture and is not eroded, so that no bubbles or peeling occur at the periphery of the windshield 1.

The automobile windshield mounting structure according to the present invention can be assembled, for example, as follows. First, a moisture-impermeable adhesive 10 is applied to the outer circumference of the windshield 1, and the molding 8 is adhered to the outer circumference of the windshield 1 so that the edge of the windshield 1 fits between the flanges 8a and 8b. . Then, the dam rubber 9 is adhered to the inner periphery of the windshield 1, and furthermore, a band-shaped sealant 6 is installed between the dam rubber 9 and the molding 8. In this state,
When the windshield 1 is pushed into the window frame 7, the sealant 6 is deformed and the windshield 1, window frame 7, and molding 8
and the area surrounded by the dam rubber 9 is filled, and these are bonded together. Along with that, Mall 8
is inserted between the outer peripheral end surface of the windshield 1 and the window frame 7 to seal them.

As explained above, according to the present invention, the moisture-impermeable adhesive applied to the outer peripheral end surface of a laminated glass type windshield and the molding bonded to the outer periphery of the windshield via the adhesive prevent moisture from being absorbed. Since this prevents the liquid from penetrating into the end face of the windshield, bubbles and peeling can be prevented from occurring at the periphery of the windshield. Therefore, in the case of a flush mount method, etc., the width of the molding can be narrowed and the design effect can be further enhanced.
