Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a fixing method for fixing a window molding to an automobile body.

<Prior Art> Conventionally, this type of wind molding fixing is known as disclosed in Japanese Utility Model Application Publication No. 53-72324, as exemplified in FIG.

To explain this structure, a recess 2 that is one size larger than the window glass 1 is normally provided on the car body, and after the top coat is baked, the lower end reaches the bottom of the recess and the upper end extends outward from the upper edge of the recess. A clip holding member 3 made of extruded resin with an almost T-shaped cross section that slightly protrudes from the top is fixed to the entire length of the window opening with double-sided adhesive tape 4, and when forming the depression, at the same time it is attached to the bottom of the depression one turn from the window glass 1. A window glass 1 is fixed on the edge of a small window opening 5 with a sealant 6, and a resin clip 8 has a claw 9 extending from the head 8b to cover the wind molding 7 with the head 8b. Push the leg portion 8a into the holding groove 3a having the non-return claw 10 in the lower half of the clip holding member 3, and then
0 are engaged and held, the upper peripheral edge of the window glass 1 is elastically pressed downward by the inner peripheral part 7a of the window molding 7, and the separator part 3b of the upper half of the clip holding member 3 is used to press the wind molding 7 This prevents the outer circumferential portion 7b from directly touching and damaging the baked painted surface of the vehicle body.

The upper end 3' of the clip holding member 3 is in the state shown by the broken line before being fixed to the vehicle body, and is deformed to the state shown by the solid line when it is fixed to the vehicle body. In the figure, D indicates a dumb rubber.

<Problems to be Solved by the Invention> However, the above-mentioned prior art has the following problems.

That is, the clip holding member 3 has a separator portion 3b.
In consideration of the certain degree of flexibility required for the clip and the rigidity that allows the lower holding groove 3a to have a certain degree of elasticity while firmly fixing the legs 8a of the clip 8, we have chosen a property that is intermediate between the two. It is integrally molded from a resin material with For this reason, the separator portion 3b has poor flexibility, and conversely, the holding groove portion 3a has poor rigidity. Furthermore, since the relatively rigid lower half of the clip holding member 3 is placed along the curved surface of the corner of the window opening, there is a risk that the clip holding member 3 may peel off at the corner due to the restoring force.

Since the clip 8 has legs 8a lowered from various places around the entire circumference of the molding 7, the holding groove 3a of the clip holding member 3 would normally be sufficient only at the position where the legs 8a are lowered, but the separator 3b
There is a lot of waste as it is integrally routed around the entire inner peripheral surface of the recess 2.

Furthermore, since the gap between the edge of the window opening and the end of the glass is narrowed over its entire length, there is not enough adhesive space for the sealant 6, resulting in a decrease in the mounting strength of the window glass 1 and water leakage. There was also a fear that Note that even if this clip holding member 3 is cut to an appropriate length and used, the separator portion 3b will also be cut, resulting in a gap between the edge of the molding 7 and the edge of the window opening, preventing water leakage. Resulting in.

<Means for Solving the Problems> The present invention has been made in order to eliminate the above-mentioned problems.The present invention is made by molding a base member having a retaining groove for a clip from a heat-resistant hard resin, and then bonding the base member with a hot-melt adhesive. A double-sided adhesive tape with a layer is temporarily fixed to the lower inner circumference of the recess around the opening of the car body at intervals corresponding to the mounting pitches of the clips, and the hot melt adhesive layer contained in the double-sided adhesive tape is heated by the heat of the heating process of painting the car body. The base member is permanently fixed by heat curing, and then a separator molded from a soft resin is fixed to the upper inner periphery of the recess in the opening periphery of the vehicle body along the entire inner periphery with double-sided adhesive tape, After fixing the separator, the window glass is fitted into the recess and fixed, and then the legs of the clip, whose head is attached to the wind molding at a predetermined pitch, which hangs down from the wind molding, are placed in the holding grooves of each of the base members. It is characterized by being pushed in from the inside.

<Example> Figures 2 and 3 show examples of the present invention, in which 11 is a base member made of a heat-resistant hard resin, such as PBT resin, and has a clip holding groove, and 12 is a base member made of a soft resin, such as soft PVC. This is a separator molded with

The base member 11 may be manufactured by extrusion molding and cutting it into an appropriate length, or may be manufactured by injection molding or the like.

Then, the base member 11 is attached to the lower part of the inner periphery of the recess 2 at the periphery of the opening of the car body using a double-sided adhesive tape 13 having a hot melt adhesive layer on both sides. Temporary fixation is performed at intervals corresponding to the above, and the top coat is baked and the hot melt adhesive layer is thermally cured by the heat during drying to permanently fix it.

Further, the separator 12 is fixed to the upper part of the inner periphery of the recess 2 at the peripheral edge of the opening of the vehicle body with a normal double-sided adhesive tape 14, for example, an acrylic adhesive tape, after the top coating of the vehicle body is completed. This adhesive tape 14 may be attached to the entire circumference of the separator 12 or may be attached partially.

After fixing the separator 12, the window glass 1 is then fitted into the recess 2 and fixed,
Then, the legs 8a of each clip 8 with its head 8b attached to the wind molding 7 are pushed into the holding groove of the base member, and as described above, the peripheral edge of the window glass is held with the inner peripheral part 7a of the wind molding. Pressure is applied downward, and the separator 12 prevents the outer peripheral part 7b of the wind molding 7 from touching the vehicle body and damaging the paint film.

<Effects of the Invention> As is clear from the above, the leg portion 8a of the clip 8
A base member 11 for fixing the molding 7 and a separator 12 for preventing the outer circumferential part of the molding 7 from touching the vehicle body are separated. and fix it in place.
The head 8b is attached to the molding 7 to strongly hold the leg part 8a of the clip that comes down from the molding.On the other hand, the separator is made of soft resin and is highly flexible, so it blends into the car body and prevents the paint film on the car body. from the outer peripheral part 7b of the wind molding 7. Furthermore, since this separator surrounds the entire circumference of the recess, it prevents rainwater, dust, etc. from entering.

Furthermore, since the base member 11 only needs to be fixed at points that match the pitches of the clips 8 attached to the molding 7, there is no waste of material, and the base member 11 is made of hot melt material that is thermoset using the heat of the heating process of car body painting. The adhesive layer allows for extremely strong fixation to the vehicle body.

Since the sealant 6 spreads to the edge of the window opening where the base member 11 is not present, not only the mounting strength of the window glass 1 is improved, but also water leakage can be prevented. Moreover, since the separator 12 is soft, it does not damage the paint film of the vehicle body, which is advantageous in terms of rust prevention.
