Description

[Detailed description of the invention] This invention relates to an assembly structure for resin fitting parts used as interior materials for interiors of automobiles, boats, etc., and uses screws and adhesives to create gaps at joints. The purpose of the present invention is to provide a structure for assembling resin fitting parts by one-touch work without any hassle.

For example, as a resin fitting part for the interior of an automobile, there is a fitting part indicated by the symbol B in FIG.
This outfitting part B is an outfitting part called a trim cover made of polypropylene, and is a hard and flexible part with high elastic restoring force. On the other hand, the rigid equipment component indicated by the symbol A in the drawing is a component called a roof finisher made of decorative steel plate, which does not undergo deformation. The outfitting part B is fixed to the body panel 2 with screws 1 at the upper and lower intermediate parts or the part hidden by other parts, and the outfitting part A is fixed at a predetermined location on the body panel 2 with screws 3. In this case, even if the upper end of the outfitting part B is designed to be in close contact with the outfitting part A, a gap S may occur between the two due to a slight error.

Therefore, as shown in the longitudinal cross-sectional view in Fig. 2, the upper end of the outfitting part B, whose intermediate part is fixed with the screw 1, is fixed to the outfitting part A with another screw 4 to prevent the occurrence of gaps. I've been doing it. However, the exposed screw heads on the fittings part B that form the interior surface seriously impairs the aesthetics, so resin fittings that can be assembled without using screws without creating any gaps are used. There has been a strong desire to develop a structure for assembling parts.

The purpose of this invention is to provide a structure for assembling resin fittings that meets the above-mentioned needs. It is made of a rich hard and flexible resin, and ribs are provided on the back of the end of this outfitting part, and the outfitting part with the ribs is assembled by being pushed in while bending.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the assembly structure for resin fitting parts of the present invention will be described below with reference to the drawings.

FIG. 3 shows a perspective view of the rigging of the rear right portion of the interior of the automobile. This embodiment is an example of a structure in which a trim cover 6 as a resin fitting part B is assembled to a roof finisher 5 as a rigid fitting part A. The roof finisher 5 is a part formed by roll or press forming a decorative steel plate, and is fixed to the roof portion of the body panel 2 in advance. The trim cover 6 is a polypropylene molded part, and although it is flexible, it has high rigidity and toughness, and particularly has a large elastic restoring force.

Figure 4 shows the assembly structure of this embodiment in Figure 3-
The portion seen along the line is shown in an enlarged cross-sectional view.

The connection between the trim cover 6 and the body panel 2 is as follows:
As shown in FIG. 4, a rivet-shaped polypropylene clipper 7 having a plurality of fins 7B is used on the leg portion 7A.

The clipper 7 is attached to the trim cover 6 by engaging the head 7C in a groove 8 formed on the back surface of the upper and lower middle portions of the trim cover 6, and press-fitting the leg 7A into a hole 9 drilled at a predetermined location in the body panel 2. 6 to the body panel 2. The diameter of the hole 9 is set to be slightly larger than the diameter of the leg portion 7A of the clipper 7, but smaller than the outer diameter of the fin 7B. That is, when the leg portion 7A of the clipper 7 is press-fitted into the hole 9, the fin 7B is bent in the direction of the head portion 7C, and when the press-fitting is completed, the fin 7B engages with the dorsal mouth edge of the hole 9 and is prevented from coming out. It is a part.

On the other hand, a rib 10 having a predetermined height and width is formed at a predetermined position on the back surface near the upper end of the trim cover 6. The rib 10 is pressed against the end surface of the roof finisher 5, and this pressing force is due to the elastic restoring force of the trim cover 6.

FIG. 5 shows an assembled state of the roof finisher 5 and trim cover 6 in an enlarged perspective view seen from the back side, that is, from the body panel side. Code 1 in Figure 5
A bracket 1 is fixed to a predetermined position on the back side of the roof finisher 5, and is provided with a screw hole 12 through which the screw 3 is inserted when the roof finisher is fixed to the body panel 2 using the screw 3 described above.

FIG. 6 is a longitudinal sectional view showing the process of assembling the trim cover 6 in this embodiment. When the trim cover 6 is in a state in which the intermediate portion is fixed to the body panel 2 by the above-mentioned clipper 7, the rib 1
0 is in contact with the surface of the roof finisher 5 on the inside of the vehicle, and is tilted toward the upper end of the trim cover under the elastic restoring force of the trim cover 6. At this time, the upper end of the trim cover 6 is slightly raised above the surface of the roof finisher 5.

From this state, when pressure is applied in the direction shown by the white arrow in FIG. The trim cover 6 falls into contact with the end surface of the roof finisher 5 due to its elastic restoring force.

Furthermore, when the top surface of the trim cover 6 (the surface facing the interior of the vehicle) is pressed with a fingertip or the like and pressed against the roof finisher 5, the upper end of the trim cover 6 will move toward the roof finisher while maintaining the engaged state by the ribs 10. Close to 5.

In the present invention having the above structure, after the trim cover 6 is fixed to the body panel 2 with the clipper 7, by simply pressing the part near the upper end, the rib 10 engages with the end of the roof finisher 5, and then this The engaged state is maintained by the elastic restoring force of the trim cover 6 itself.

FIG. 7 shows an embodiment of the present invention in other parts. This embodiment is an assembly structure in which the rear parcel shelf 13 is a rigid fitting part A, and the trim cover 6 is a resin fitting part B.

In this case as well, a rib 10' is provided on the rear surface near the lower end of the trim cover 6, and FIG.
As shown in the enlarged longitudinal sectional view taken along the line, the ribs 10' engage with the edges of the rear parcel shelf 13 by simply pushing the trim cover 6 in the direction indicated by the white arrow.

As is clear from the above explanation, in the present invention, the ribs engage with the rigid outfitting part A by simply pushing the resin outfitting part B against the rigid outfitting part A that has been fixed in advance. The time and effort required to assemble parts can be greatly reduced, the assembly work in the production line can be streamlined, and once assembled, there is no fear that the resin fittings B will fall out, and in particular, the rigidity of the assembly partner can be reduced. It has the advantage that there is no gap between it and the outfitting part A, and since no screws are used, there is no risk of spoiling the aesthetics.
