Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative member for a vehicle, and more particularly to a decorative member for a vehicle using a transparent or translucent light-transmitting synthetic resin.

Generally, decorative members made of synthetic resin and having a certain pattern such as lines or dots are attached to the inner and outer surfaces of a vehicle.

The decorative member is made by applying a first coating as a pattern by masking a desired part of the back surface of a transparent synthetic resin plate, and then applying a second coating having a different color tone from the first coating. It is obtained by applying and baking the coating, including the coating part, and is attached to the interior and exterior surfaces of the automobile after completion.

In this case, when looking at the first coating part from the surface side,
This first coated portion appears as a pattern, providing a decorative effect.

However, with the above configuration, it is difficult to obtain a pattern with a three-dimensional effect, and if the first coating peels off over many years, the aesthetic appearance will be significantly reduced, and two coating operations and two baking operations are required. Because of this, the number of manufacturing steps becomes complicated and manufacturing costs increase, and the molded product is thermally deformed due to baking.

SUMMARY OF THE INVENTION An object of the present invention is to provide a decorative member for a vehicle in which a pattern or the like is substantially added by forming an uneven surface on the back surface of a synthetic resin plate, thereby eliminating the above-mentioned drawbacks.

Another object of the present invention is to have a reinforcing effect and increase mechanical strength.

Another object of the present invention is to prevent the color tone from changing even after long-term use, which will be explained in detail below using Examples.

FIG. 1 is a sectional view showing one embodiment of a vehicle decorative member according to the present invention, FIG. 2 is a plan view of the main part thereof, and FIG. 3 is an enlarged sectional view. This plate is made of a light-transmitting synthetic resin, and is made of acrylic resin, polycarbonate resin, nylon, etc., and has a flat part 3 parallel to the mounting surface 2 of the vehicle, and a tongue part 5 having a step 4 and parallel to the mounting surface 2. and a leg piece 6 that protrudes in the direction of the mounting surface 2, and has a cross-sectional shape that approximates a C-shape.

Note that the plate 1 is not limited to the C-shaped cross-sectional shape, but can be deformed into various shapes depending on where it is mounted on the vehicle.

A cushioning member 7 made of rubber or the like is provided at the end of the leg piece 6 to prevent dirt and the like from entering and to prevent the tip of the leg piece 6 from damaging the vehicle.

The third surface side 8 of the flat part is a smooth surface without any unevenness added, and the back side thereof is an uneven surface 9 that has a serrated shape along the width 10 direction. color layer 1
1 is deposited.

The coloring 11 is formed by applying a paint containing aluminum powder or the like, and is formed by vapor deposition, sputtering, or plating of chromium or aluminum.

The surface side 8 of the flat portion 30 is coated with a well-known material to improve weather resistance and abrasion resistance.

Note that this protective coating layer 12 may cover the color layer 11.

In such a configuration, the light 13 that enters the uneven surface 9 from the front side is reflected by the surface 14 with a large inclination angle and the surface 15 with a small inclination angle, but is reflected by the surface 14 with a large inclination angle. Since the light is reflected at a larger reflection angle than the light reflected from the surface 15 with a small inclination angle, when this part 14 is viewed from the surface side, it looks black, and this makes it possible to obtain a linear pattern, and the color is also different. The light reflecting ability of the layer 11 can increase the pattern contrast and make the pattern visible in a highlighted manner.

Further, according to this embodiment, since the coating layer 12 is provided, the surface of the plate 10 and the color layer 11 can be protected from external impact, and the convex strips 91 on the uneven surface 9 on the back side function as ribs. The strength of the entire plate 1 can be increased.

Further, the buffer member 1 can prevent dirt from entering the inside of the plate 1, and the disadvantage that the ends of the legs 6 may damage the surface of the vehicle can be eliminated.

In particular, an important effect of the present invention is that the uneven surface 9, which serves as a means for adding a pattern, can be formed simultaneously with the plate body by injection molding.

Therefore, the conventional series of operations for adding patterns, such as masking, coating, and baking, can be omitted, making it possible to mass-produce the product and reducing costs.

FIG. 4 is a sectional view of a main part showing another embodiment of the vehicle decorative member according to the present invention, and the same part as in FIG. 6 uses No. 4.

In FIG. 4, a surface 15 with a small inclination angle and a surface 1 with a large inclination angle
The joint with 4 has a curved shape.

In this way, it becomes possible to blur the edges of the pattern, and it is possible to obtain an interesting decorative member.

Further, in the present invention, the plate 1 may be formed from a colored synthetic resin.

In this way, the interest can be further increased.
