Description

[Detailed Description of the Invention] This invention relates to a structure for attaching automobile window glass using an adhesive.

In contrast to the general mounting structure for window glasses that uses weather strips, recently there has been an increase in the number of window glasses that are attached to the vehicle body by adhesive. According to this, it is lightweight and can be constructed at low cost with few irregularities on the outside, and the rigidity of the mounting portion is increased, and visibility can be improved. (For example, see Utility Model Application Publication No. 50-20315.) The present invention is a further improvement on this mounting structure, which simplifies the structure, reduces the number of parts, and improves the aesthetic appearance of the interior. , Before proceeding with this explanation, a general mounting structure using an adhesive will be explained using a general example shown in FIG.

In FIG. 1, a window frame portion 1 of a vehicle body is formed by overlapping a flange portion 2a of an outer panel 2 and a flange portion 3a of an inner panel 3 and fixing them by spot welding 4. A flexible dam member 6 made of rubber or plastic is fixed to the indoor side peripheral edge 5a of the window glass 5 with an adhesive 7. And the flange portion 2a of the outer panel 2
When bonding the window glass 5 with the adhesive 8, the dam member 6 is brought into contact with the flange portion 2a,
It is designed to prevent the adhesive 8 from flowing out.

Then clip 9 to the shoulder 2b of the outer panel 2.
is fixed with an adhesive 10 or the like, and a molding 11 is secured to this. Further, a garnish 13 is attached to span between the end portion 12a of the trim panel 12 attached to the indoor side of the inner panel 3 and the window glass 5.

When forming the window frame part 1, impressions from the spot welding 4 remain on the flange part 3a of the inner panel 3, which spoils the aesthetics of the room, and burrs remain on the ends of the flange parts 2a and 3a. Passengers may be injured if they come into contact with the garnish, but the garnish 13 is provided to cover up these and improve the appearance, and to ensure the safety of the passengers.

In contrast, the present invention is designed as shown in the embodiment shown in FIG. 2, and its configuration will be explained as follows. (The same structural parts as in the above general example are indicated by the same numbers.) The trim member 14 is made of a rubber material or a plastic material, and includes a dam part 14a and a fin part 14b, and comes into contact with the adhesive 8 at the dam part 14a. A joint portion 14c is provided on the surface. Each of these parts is integrally molded by a method such as triple extrusion so as to have different hardness.

The dam part 14a is hard molded, and is brought into contact with the flange part 2a of the outer panel 2.
The adhesive 8 for attaching the flange portion 2a and the window glass 5 is prevented from flowing out through the soft joint portion 14c.

Since the dam part 14a is formed hard, it becomes a spacer that determines the relative position of the window glass 5 with respect to the window frame part 1 when brought into contact with the flange part 2a.
Further, the joint portion 14c has flexibility, and its tip portion is 14 when not in contact with the flange portion 2a.
c' shape, but when brought into contact with the flange portion 2a, it bends along the flange portion 2a and maintains airtightness.

The fin portion 14b is formed to be soft and flexible, and covers the indoor side of the flange portion 3a of the inner panel 3. Before covering the fin portion 14b, the tip portion 14d is folded in. It locks into the engagement groove 14e provided on the back surface of the dam part 14a, and its shape is changed to 14.
As shown in b', the fins should not come into contact with the adhesive 8 during the gluing process.

Furthermore, when the fin part is formed into the shape 14', if the working string 15 is inserted into the bent part and the working string 15 is pulled out after the gluing work is completed, the fin part 14b' It shifts from this state and comes to cover the indoor side of the flange portion 3a of the inner panel 3 due to its elasticity. Therefore, the garnish 13 becomes unnecessary.

As shown in FIG. 3, if the tip of the fin portion 14b is shaped like a beaded edge 14d' and is engaged with the engagement groove 14e' provided in the dam portion 14a, This is advantageous because the locked state is reliably maintained. Furthermore, when the flange portion 3a is displaced toward the indoor side, the corner portion of the flange portion 3a is better contacted, resulting in a more aesthetically pleasing appearance.

As mentioned above, the present invention eliminates the need for a garnish that covers the indoor side of the window frame by providing a trim member that is integrally formed with a dam part that prevents adhesive from flowing out and a fin that covers the indoor side of the window frame. , the structure is simplified and the number of parts can be reduced. In addition, since the dam part of the trim member is molded hard and the fin part is molded soft, the relative position between the window frame part and the window glass can be determined reliably, and the flexible fin part can be molded into the room. It has various features such as being able to transpose inward to improve the aesthetics of the interior.
