Abstract

PURPOSE:To simply obtain a decoration pattern with a long life by making the surface side of a light transparent synthetic resin plate a smooth face, making its back side a rugged face, and forming the rugged face with a face having a large tilt angle and a face having a small tilt angle. CONSTITUTION:A plate 1 made of synthetic resin such as transparent or semi- transparent acrylic resin is formed into a proper shape, e.g., C-cross section, in response to the fitting position to a car. The plate 1 is provided with a flat section 3 in parallel with the fitting face 2 to a car, a tongue section 5 with a step 4 and in parallel with the fitting face 2, and a leg piece 6 protruding in the fitting face 2 direction, and a cushioning member 7 is provided on the tip of the leg piece 6. In addition, the surface side of the flat section 3 is made a smooth face 8, and its back side is made a rugged face 9 with a sawtooth shape along the width 10 direction and a color layer 11 is deposited on the rugged face 9. Accordingly, light rays 13 incoming to the rugged face 9 side from the surface side are reflected at different angles by a face 14 with a large tilt angle and a face 15 with a small tilt angle, thus a pattern can be obtained.

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 a nine-point linear pattern 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 the first coated portion is viewed from the front side, the 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 deteriorate significantly, and two coating operations and two baking operations are required. As a result, the number of manufacturing steps becomes complicated and the manufacturing cost increases, and there are also disadvantages such as thermal deformation of the molded product for 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 FIGS. 3 and 4 are enlarged sectional views. Alternatively, it is a plate made of translucent light-transmitting synthetic resin, made of acrylic resin, polycarbonate resin, nylon, etc., and has a flat part 3 parallel to surface 2 and a step 4 for mounting on the vehicle. It consists of a tongue part 5 parallel to the mounting surface 2, and a leg piece 6 projecting in the direction of the mounting surface 2, and has a cross-sectional shape approximating 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 the mounting location on the vehicle. The ends of the leg pieces 6 are designed to prevent dirt from entering, and
A cushioning member 7 made of rubber or the like is provided to prevent the end of the leg piece 6 from damaging the vehicle.

The front side 8 of the flat part 30 is a smooth surface with no unevenness added, and the back side thereof is an uneven surface 9 that is sawtoothed along the width direction 10, and the uneven surface 9 has a color. layer 1
1 is deposited. The color layer 11 is formed by applying a paint containing aluminum powder, vapor depositing or sputtering chromium or aluminum, or plating.

The surface side 8 of the flat portion 3 is coated with a well-known substance 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. 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 appears blackish (this makes it possible to obtain a linear pattern). Furthermore, due to the light reflecting ability of the color layer 11, the contrast of this pattern can be increased, and the pattern can be visually observed in a highlighted manner.

Further, according to this embodiment, since the coating layer 12 is provided, the surface of the plate 1 and the color layer 11 can be protected from external impact, and the convex strips 9I are formed as ribs on the uneven surface 9 on the back side. This has the effect of increasing the strength of the entire plate 1. In addition, the buffer member 7 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 molded 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.

In the present invention, the plate 1 may be formed from a colored synthetic resin. In this way, the interest can be further increased.
