Abstract

PURPOSE:To aim at a reduction in the number of parts items and work processes as well as improvements in sealability, by solidly installing a spacer for windowpane positioning use in advance in a part of dam rubber used for checking a bonding agent leakage, in case of a bonded window structure for automobiles. CONSTITUTION:A bonded window structure for automobiles is provided with a spacer for windowpane positioning and dam rubber for checking a bonding agent leakage. In this case, the dam rubber 8, forms a V-groove 12 at a proper spot, and a spacer 7, is solidly locked in advance so as to engage with this V-groove 12. And, in time of operation, first the dam rubber 8, is stuck to an inside edge part 2a of a front windowpane 2, then a bonding agent 9 is applied to the neighborhood and after that, the windowpane 2 is pressed to a window edge part 6 and made to adhere thereto, thus setting is completed. As a result, simultaneously with the setting of the dam rubber 8, the spacer 7, can be set up there. Therefore, not only the number of parts items and work processes can be reduced but also good sealability can be secured.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bonded window structure for an automobile. Conventional bonded window structures include those shown in FIGS. 1 and 2, for example. 1 is a car, and 2 is a front window glass. This front window glass 2I/i, roof panel 6, front pillar 4,
It is attached by adhesive to the window opening edge 6 of the vehicle body formed by the cowl panel 5 and the like. That is, when bonding the front window glass 2, specifically, the window opening edge 6, for example, the 7 flange portion 6a of the roof panel 3 is bonded.
Spacers 7 are bonded at appropriate intervals (four locations in FIG. 1) to the inner edge 2a of the front window glass 2.
After affixing the dumb rubber 8 to the window and applying adhesive 9 around it, the freon and window glass 2 are pressed against the window opening edge 6 to bring them into close contact.

In this case, the front window glass 2 and the window opening edge 6
It is possible to position the front window glass 2 with respect to the window opening edge 6 and to hold a predetermined amount of adhesive 9 by the spacer 7 arranged between the dam rubber 8 and the dam rubber 8.
This prevents the adhesive 90 from leaking to the interior side A of the vehicle.

In addition, I11 edge 2aK of the front window glass 2
A black print 10 is applied to prevent the spacer 7, dam rubber 8, adhesive 9, etc. from being seen from the outside side B. Further, 11 is a molding that covers the outer periphery of the front window glass 2.

It is

However, in such a conventional adhesive window structure, as shown in FIG. It is easy to get into a situation where the product does not come into close contact with the
There was a problem in that the sealing performance of that part deteriorated.

To solve this problem, it is sufficient to ensure a wide adhesive width W, but if the adhesive width W is wide, the actual opening of the window will inevitably become smaller and the visibility will become narrower, and in addition, a larger amount of adhesive will be required. In addition, the adhesive window structure in which spacers are placed in advance at the window opening edge 6 is preferable in terms of work efficiency and management of each component. It was indescribable.

This invention was made by paying attention to such conventional problems, and it is possible to achieve good sealing performance without particularly increasing the adhesive width or increasing the amount of adhesive. The purpose is to provide a bonded structure with a small number of parts and excellent workability.

With this intention in mind, the present invention is characterized in that the spacer is integrally provided with a part of the dam rubber, and the actual arrangement of the spacer can be completed at the same time as the dam rubber is disposed. This aims to improve sealing performance and workability.

The present invention will be explained below based on the drawings. In the following, in each embodiment of the present invention, the same reference numerals will be used for the same parts as in the past, with only the suffix changed as appropriate, and V
Duplicate explanations and duplicate illustrations will be omitted.

3 to 5 are diagrams showing one embodiment of the present invention.

The figure shows dam rubber 8. which is integrally equipped with spacer O. It shows. The dam shield 81 has a substantially square cross section and is made of a conventional elastic material. And this Damla, bar 8. A KV groove 12 is formed at an appropriate location of the spacer 7, and the spacer 7 is fixed to the two bodies so as to engage with the V groove 12 of the spacer 7.
By changing the cut 71 (t) of the top part 16 of 1, it is possible to arbitrarily adjust the desired spacer height h according to various car models.

This adhesive window structure is made of dumb rubber 8. with spacer 71. First, use this dam rubber 8. to the inner edge 2a of the front window glass 2, then apply the VC adhesive 9 around it, and then press the front window glass 2 against the window opening edge 6 to tightly fit and fix it, and the installation is completed. do. In addition, this dam rubber 81
It is sufficient if it is placed between the front window glass 2 and the window □ opening edge 6.) It should be attached in advance to the window opening edge/section 6 rather than to the own window glass 2. The above-mentioned pressing can be performed freely. dumb rubber 8
It goes without saying that arranging spacer 71 at the same time as arranging spacer 71 becomes . Also, spacer 7. :II
C=Good The adhesion of the adhesive 9 to the window opening edge 6 does not deteriorate.

Although the front window structure has been described above, the rear window structure etc. can also be considered in exactly the same way.

Other embodiments of the present invention are shown in FIGS. 6 to 9, respectively.

In the embodiment shown in FIG. 6, a slit 14 is cut in the dam rubber 8□ having a substantially square cross section, and a cylindrical spacer 72 is buried in the slit 14. ．． 7. It integrates the The spacer height h is determined by the outer diameter of the cylinder.

The embodiment shown in FIG. 7 is a dam rubber 8. whose cross section is approximately square. By forming a rectangular recess 15 in and engaging the rectangular spacer 73 in the recess 15, both 8. ．． 7. are integrated. The spacer height can be set arbitrarily.

In the embodiment shown in FIG. 8, the dam rubber 84 and the spacer 7° are laminated and integrated. This embodiment has the advantage of being easy to manufacture, such as by being able to use extrusion molding. When installing, either side may be used facing the front window glass 2 side.

The embodiment shown in FIG. 9 uses dam rubber 85 in order to maintain good flexibility at a part of the corner of the front window glass 2.
The inner spacer 75 is formed only at a predetermined portion 16 to a desired spacer height h.

In addition, both 7. ．． When rolling and adhering 85, use dam rubber &
In this case, the recess 17 having a depth of d does not necessarily need to be provided in advance.

As explained above, according to the present invention, the spacer is integrated with a part of the dam rubber in advance, and the spacer is attached separately in addition to the dam rubber. This reduces the number of parts and the number of man-hours required. Furthermore, since there is no interference between the adhesive and the spacer, good sealing performance can be ensured without particularly increasing the adhesive width.

Therefore, there is no problem with visibility or the need for a large amount of adhesive.
