Abstract

In a resin decorative part, a clear decoration has a body transmitting light and includes a carbon-toned surface provided on the opposite side to the viewer side of the body and having a carbon-toned pattern. The carbon color layer is colored in a carbon color, is laminated on the carbon-toned surface, and has a reflective surface reflecting light transmitted through the clear decoration. The carbon-toned pattern is formed with a plurality of pseudo carbon fiber bundles presenting carbon fiber bundles formed by bundling carbon fibers in a pseudo manner. The pseudo carbon fiber bundle has a plurality of linear grooves that constitute pseudo carbon fibers presenting carbon fibers in a pseudo manner. The carbon-toned surface includes a pseudo carbon fiber bundle in which the length in the extending direction of each linear groove and the depth of the linear groove vary in a predetermined range.

First claim

What is claimed is:

1. A resin decorative part comprising:
a clear decoration having a body transmitting light, the clear decoration including a carbon-toned surface disposed on an opposite side to a viewer side of the body and having a carbon-toned pattern; and
a carbon color layer colored in a carbon color and laminated on the carbon-toned surface, the carbon color layer having a reflective surface reflecting light transmitted through the clear decoration, wherein
the carbon-toned pattern is formed with a plurality of pseudo carbon fiber bundles presenting carbon fiber bundles formed by bundling carbon fibers in a pseudo manner,
the pseudo carbon fiber bundle has a plurality of linear grooves that constitute pseudo carbon fibers presenting the carbon fibers in a pseudo manner, and
the carbon-toned surface includes the pseudo carbon fiber bundle in which a length in an extending direction of each linear groove and a depth of the linear groove vary in a predetermined range.

2. The resin decorative part according to claim 1 , wherein
the carbon-toned surface includes a plurality of unit patterns that constitute a weave of the pseudo carbon fiber bundles, and
the unit patterns include the unit pattern in which a length in an extending direction of each linear groove and a depth of the linear groove vary in a predetermined range.

3. The resin decorative part according to claim 2 , wherein
the unit patterns are formed such that a length in a long side direction is 4 mm and a length in a short side direction is 2 mm, and
the linear grooves are formed such that a length in an extending direction of each linear groove is in a range of 1 mm to 4 mm and a depth of the linear groove is in a range of 0 μm to 3 μm at random.

4. The resin decorative part according to claim 3 , wherein
the linear groove is formed to be depressed from a reference plane of the carbon-toned surface along a deepness direction, and
a depth of the linear groove is a distance between the reference plane and a bottom portion of the linear groove in the deepness direction.

5. The resin decorative part according to claim 2 , wherein
the linear groove is formed to be depressed from a reference plane of the carbon-toned surface along a deepness direction, and
a depth of the linear groove is a distance between the reference plane and a bottom portion of the linear groove in the deepness direction.

6. The resin decorative part according to claim 1 , wherein
the linear groove is formed to be depressed from a reference plane of the carbon-toned surface along a deepness direction, and
a depth of the linear groove is a distance between the reference plane and a bottom portion of the linear groove in the deepness direction.

7. A dial plate comprising:
a clear decoration having a body disposed in a vehicle and transmitting light, the clear decoration including a carbon-toned surface disposed on an opposite side to a viewer side of the body and having a carbon-toned pattern;
a carbon color layer colored in a carbon color, laminated on the carbon-toned surface, and including a reflective surface reflecting light transmitted through the clear decoration;
a low reflection layer laminated on the viewer side of the body to suppress reflection of light; and
a design display section disposed on the body and transmitting light such that a design related to the vehicle is illuminated, wherein
the carbon-toned pattern is formed with a plurality of pseudo carbon fiber bundles presenting carbon fiber bundles formed by bundling carbon fibers in a pseudo manner,
the pseudo carbon fiber bundle has a plurality of linear grooves that constitute pseudo carbon fibers presenting the carbon fibers in a pseudo manner, and
the carbon-toned surface includes the pseudo carbon fiber bundle in which a length in an extending direction of each linear groove and a depth of the linear groove vary in a predetermined range.

8. A resin decorative part comprising:
a clear decoration having a body transmitting light, the clear decoration including a carbon-toned surface disposed on a viewer side of the body and having a carbon-toned pattern; and
a colored layer laminated on an opposite side to the viewer side of the body and colored in a carbon color, wherein
the carbon-toned pattern is formed with a plurality of pseudo carbon fiber bundles presenting carbon fiber bundles formed by bundling carbon fibers in a pseudo manner,
the pseudo carbon fiber bundle has a plurality of linear protrusions that constitute pseudo carbon fibers presenting the carbon fibers in a pseudo manner, and
the carbon-toned surface includes the pseudo carbon fiber bundle in which a length in an extending direction of each linear protrusion and a height of the linear protrusion vary in a predetermined range.

9. The resin decorative part according to claim 8 , wherein
the carbon-toned surface includes a plurality of unit patterns that constitute a weave of the pseudo carbon fiber bundles, and
the unit patterns include the unit pattern in which a length in an extending direction of each linear protrusion and a height of the linear protrusion vary in a predetermined range.

10. The resin decorative part according to claim 9 , wherein
the unit patterns are formed such that a length in a long side direction is 4 mm and a length in a short side direction is 2 mm, and
the linear protrusions are formed such that a length in an extending direction of each linear protrusion is in a range of 1 mm to 4 mm and a height of the linear protrusion is in a range of 0 μm to 3 μm at random.

11. The resin decorative part according to claim 10 , wherein
the linear protrusion is formed to protrude along a height direction from a reference plane of the carbon-toned surface, and
a height of the linear protrusion is a distance between the reference plane and a top portion of the linear protrusion in the height direction.

12. The resin decorative part according to claim 9 , wherein
the linear protrusion is formed to protrude along a height direction from a reference plane of the carbon-toned surface, and
a height of the linear protrusion is a distance between the reference plane and a top portion of the linear protrusion in the height direction.

13. The resin decorative part according to claim 8 , wherein
the linear protrusion is formed to protrude along a height direction from a reference plane of the carbon-toned surface, and
a height of the linear protrusion is a distance between the reference plane and a top portion of the linear protrusion in the height direction.
