Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a windshield glass mounting structure, and specifically relates to an improved structure that can significantly improve the mounting workability and ensure mounting strength.

[Conventional technology]

Recently, front windshield glass of automobiles has been manufactured with the main purpose of improving installation workability, as shown in, for example, Japanese Utility Model Application Publication No. 55-42617 or No. 58-47511.
Adhesive mounting structures are often used. As shown in FIG. 5 of the present application, the windshield glass mounting structure using such adhesive forms a mounting surface c parallel to the windshield glass b around the front window opening of the vehicle body a, while also forming a mounting surface c parallel to the windshield glass b. A dam lip d is adhesively fixed in advance to the back surface slightly inward from the periphery of the shield glass b, and this windshield glass b is
is held at a constant distance from the mounting surface c so that the tip of the dam lip b is in close contact with the mounting surface c, and the windshield glass b is
It is constructed by filling a space e surrounded by the back surface, the mounting surface c, and the dam lip d with an adhesive f. A molding g is fitted into the gap between the periphery of the windshield glass b and the vehicle body a.

[Problem that the idea aims to solve]

However, even with the above structure, the following problems still occur. First, it is necessary to adhesively fix the dam lip d to a predetermined position on the back surface of the windshield glass b in advance, which increases the number of steps and the number of parts. Second, a means for holding the windshield glass b at an accurate fixed distance from the mounting surface c of the window opening is required, and the construction of that means is costly. If the distance between the held windshield glass b and the mounting surface c is uneven at various places around the window opening, there will be parts where the sealing of the dam lip d to the mounting surface c is incomplete, and if this happens, the outside of the dam lip d A problem arises in that the adhesive material f filled in the space enters into the passenger compartment. Thirdly, the amount of adhesive to be filled in the space e is relatively large, and this
It is difficult to fill the area uniformly around the area. Fourth, since the bonded portion is almost directly exposed to solar heat, there is a risk that the adhesive holding power of the adhesive may deteriorate over time. Fifth, since the molding g is fitted and attached so as to overlap the upper surface of the peripheral edge of the windshield glass b, a step cannot help but occur between the surface of the windshield glass and the molding g.
This prevents the car body from becoming a flat surface, and does not necessarily give a good appearance. This invention was devised under the above-mentioned circumstances, and can further improve installation workability compared to the conventional example described above, and can maintain a constant installation quality. Moreover, it is an object of the present invention to provide a new windshield glass mounting structure that can ensure mounting stability and furthermore enable the windshield glass mounting portion to be made into a flat surface.

[Means to solve the problem]

In order to solve the above problems, the present invention takes the following technical measures. That is, in the present invention, an elastically deformable strip-shaped double-sided adhesive means is pasted on one side of the attachment surface provided around the window opening of the vehicle body or on the back surface of the peripheral edge of the windshield glass, and this double-sided adhesive means The windshield glass is temporarily held in a predetermined position by adhering the other side to the back surface of the peripheral edge of the windshield glass or the mounting surface of the vehicle body, while the entire circumference of the windshield glass is fixed to the mounting surface. It is pressed and fixed by a clamp molding having a generally round-shaped cross section, which has a mounting part that is attached to the mounting part, a standing part that rises from the inner edge of the mounting part, and a glass holding part that extends inward from the upper edge of the standing part. In addition, a molding that covers the mounting base of the clamp molding is attached to the entire circumference or a part of the circumference of the windshield glass.

[Effect]

The elastically deformable double-sided adhesive means, which is attached to the back side of the windshield glass or the mounting surface of the vehicle body before the windshield glass is held in place, is used during and after the installation of the windshield glass. function is given. The first is the function of temporarily holding the windshield glass in a predetermined position in the window opening before it is fully fixed with the clamp molding, and the second is the function of temporarily holding the windshield glass in a predetermined position in the window opening before it is fully fixed with the clamp molding. The third function is as a sealing member that is compressed and arranged between the mounting surface and the mounting surface, and the third function is a buffer function to prevent vibrations of the vehicle body from being directly transmitted to the windshield glass. As this double-sided adhesive means, a commercially available product made of urethane foam or urethane rubber coated with an adhesive adhesive on both sides can be used. In addition to the function of permanently fixing the windshield glass temporarily held by the double-sided adhesive means to the window opening as described above, the clamp molding also has a separate molding that covers the mounting base of the clamp molding. In cooperation with this, it also functions as a molding that covers the peripheral edge of the windshield glass. That is, since this clamp molding is formed so as to cover the entire circumference of the windshield glass, sufficient fixing force for the windshield glass can be obtained even if the plate thickness is made relatively thin. At the same time, since the above-mentioned another molding is installed so as to cover the mounting base of the clamp molding having a substantially round-shaped cross section, it is possible to eliminate the level difference between the surface of this other molding and the glass holding part of the above-mentioned clamp molding. Because it is possible. Therefore, since the plate thickness of the clamp molding can be made thinner and it is also possible to eliminate the level difference between the surface of the additional molding and the glass holding part of the clamp molding, the windshield It is also possible to achieve a high degree of crash surface ace of the vehicle at the glass periphery. In addition, since the clamp molding is attached to cover the entire circumference of the windshield glass as described above, it is possible to prevent the adhesive in the double-sided adhesive means from leaking to the outside. Adhesive materials can be saved, and more reliable adhesion of the windshield glass and sealing between the windshield glass and the vehicle body can be achieved.

【effect】

From the above, the windshield glass mounting structure of the present invention exhibits the following unique effects. Double-sided adhesive is pasted on the windshield glass or vehicle body mounting surface in advance, so
By simply lightly applying the windshield glass to a predetermined position, the windshield glass can be temporarily held at a certain accurate position without requiring a specially constructed means for holding the windshield glass as in the past. Since the windshield glass is temporarily held in a fixed position by the double-sided adhesive means on the back surface as described above, the subsequent fixing operation using the clamp molding can be performed accurately, quickly and easily. Further, during the full-scale fixing work using the clamp molding, there is nothing on the surface of the windshield glass that obstructs the work, so the fixing work using the clamp molding becomes easier. The windshield glass will ultimately be fixed around its entire circumference with clamp molding, so
Even if the plate thickness of the clamp molding is made thin, the mounting state can be ensured and sufficiently stable. In particular, since a separate molding is attached to cover the mounting portion of the clamp molding, which is formed in a cross-sectional shape, to the vehicle body, the glass holding portion of the clamp molding and the surface of the other molding are connected. It is also possible to eliminate the step, and this, combined with the fact that the clamp molding itself can be made thin, makes it possible to achieve a high degree of crash surface of the vehicle at the peripheral edge of the windshield glass. .

[Explanation of Examples]

Hereinafter, embodiments of the windshield glass mounting structure of the present invention will be specifically described with reference to the drawings. As shown in FIG. 1, the window opening is surrounded by the front edge 1a of the roof 1, the left and right front pillars 2, and the cowl. FIG. 2 shows the mounting structure of the windshield glass 3 on the front pillar 2. The front pillar 2 in this example is configured to be compatible with a door without a door. That is, this pillar 2 specifically uses a lip groove section 5 arranged so that the groove 3 faces the inner surface of the door opening, and both side edges 6, 6 are formed on both side walls 7, 7 of this lip groove section 5. The panel member 9 is polymerized and welded to the outside, and cooperates with the bottom wall portion 8 of the lip groove section 5 to form a substantially triangular closed cross-sectional structure. A weather strip 11 that comes into contact with the door glass 10 to perform a sealing action is attached to the groove 4 of the lip groove section 5 by filling and bonding its base. The inner side edge 6 of the panel member 9 is extended downward, and the trim 12
is installed. The front-facing wall surface of the panel member 9 is used as a mounting surface 13 parallel to the windshield glass 3. Peripheral back surface 3 of the above windshield glass 3

A strip-shaped double-sided adhesive means 14 that can be elastically deformed is pasted on one side 14a of the double-sided adhesive means 1.
This windshield glass 3 is temporarily held in a predetermined position by using the adhesive force of the other surface 14b of the windshield glass 3. As the double-sided adhesive means 14, a commercially available product formed by forming a strip of urethane foam, urethane rubber, rubber, or the like with a rectangular cross section and applying an adhesive material to both the front and back surfaces of the strip can be used. The windshield glass 3 temporarily held in this manner has a mounting portion fixed to the mounting surface 13, a rising portion rising from the inner edge of the mounting portion, and a glass holder extending from the upper edge of the rising portion toward the inner edge. By fixing the mounting base 15a of the clamp molding 15, which has a substantially round-shaped cross section, to the mounting surface 13 with tapping screws 16, etc., the clamp molding 15 is pressed and fixed against the mounting surface 13 around the entire circumference. In this fixed state, it is preferable that the double-sided adhesive means 14 is slightly compressed and deformed from its natural state. Note that a thin rubber sheet 17 or the like is interposed between the clamp molding 15 and the windshield glass 3. The mounting base of the clamp molding 15, the screws 16 or the welding marks between the lip groove shaped steel and the panel member 9, which appear on the outside of the panel member 9 of the pillar 2, are attached to the outer surface of the panel member 9 with an adhesive member 18, etc. It is obscured by the attached molding 19. Next, the mounting structure of the windshield glass 3 at the front edge of the roof 1 is shown in FIG. A flange-shaped mounting surface 20 is formed on the front edge 1a of the roof panel 1 in a step parallel to the windshield glass 3, and a windshield head inner panel 2 is formed on the back surface of this.
The front edge portion 21a of the first one is welded. After temporarily holding the windshield glass 3 on the mounting surface 20 through the double-sided adhesive means 14, the periphery of the windshield glass 3 was shaped into a cross-section in the same way as explained in the structure of the pillar section. It is pressed and fixed with a clamp molding 15. A groove formed between the clamp molding 15 and the stepped portion 1b of the roof panel is filled with a molding 22, and the tapping screws 16 and the like inside the groove are filled with the clamp molding 1.
It covers the mounting base of 5. Further, a trim 24 is placed over the front edge of the roof panel 1 and the front edge of the windshield header inner panel 21 so as to sandwich the edge of the rooflining material 23. Next, the mounting structure of the windshield glass 3 in the cowl portion is shown in FIG. The joint part of the rear edge part 25 of the cowl top panel 25 with the dash panel 27 is raised slightly so as to be parallel to the windshield glass 3 to form a mounting surface 26. Similarly, after temporarily holding the windshield glass 3 through the double-sided adhesive means 14,
This windshield glass 3 is fixed with a clamp molding 15. In this example, the rear edge of the engine hood 28 is connected to the windshield glass 3.
It extends overlapping the upper edge of the lower part of the
No particular means is provided for covering the tapping screws 16 for fixing the clamp molding 15 and the mounting base of the clamp molding 15. It goes without saying that the scope of the present invention is not limited to the embodiments described above. In particular, the specific structure of the vehicle body side, ie, the specific structure of the pillar and the specific structure of the front and rear of the roof, does not matter.
