Abstract

A ligneous decorative design part having a high degree of originality and excellent design, and exhibiting a novel handsome appearance, due to properties of a ligneous material which has translucency when impregnated with a resin material. The ligneous decorative design part has a surface layer portion including a ligneous sliced veneer which is impregnated with a resin material and disposed on a side of a front surface of the surface layer portion, and which defines a decorative design surface, and a base layer portion superposed on a back surface of the surface layer portion, and formed integrally with the surface layer portion. The surface layer portion has translucency, and the ligneous decorative design part further includes another material interposed between the surface layer portion and the base layer portion and which is visible on a side of the front surface of the surface layer portion.

First claim

The invention claimed is:

1. A ligneous decorative design part comprising:
a translucent surface layer portion including a ligneous sliced veneer impregnated with a resin material and disposed on a side of a front surface of the translucent surface layer portion, and which defines a decorative design surface of the ligneous decorative design part;
a base layer portion superposed on a back surface of said translucent surface layer portion, and formed integrally with said translucent surface layer portion; and
another material, selected from the group consisting of plant leaves and insects, interposed between said translucent surface layer portion and said base layer portion,
wherein said another material is visible on the side of the front surface of said translucent surface layer portion,
wherein said translucent surface layer portion is a laminar body consisting of said sliced veneer and a translucency adjustor layer made of a ligneous material impregnated with a resin material, and integrally formed on a back surface of said sliced veneer,
wherein said base layer portion is translucent and is made of a ligneous material impregnated with a resin material, and
wherein the translucency of said surface layer portion is adjusted by said translucency adjustor layer such that said another material is not visible on the side of the front surface of said surface layer portion when the ligneous decorative design part is not exposed to a light generated by a light source disposed on a side of a back surface of said base layer portion, and is visible on the side of the front surface of said translucent surface layer portion when the ligneous decorative design part is exposed to the light generated by said light source.

2. The ligneous decorative design part according to claim 1 , wherein a translucency of said another material is different from the translucency of said translucent surface layer portion, or a wavelength of light transmitted through or reflected by said another material is different from a wavelength of light transmitted through or reflected by said translucent surface layer portion.

3. The ligneous decorative design part according to claim 1 , wherein said sliced veneer is impregnated with a melamine resin.

4. An automotive vehicle interior part consisting of the ligneous decorative design part according to claim 1 , and which is configured to be installed in a compartment of an automotive vehicle such that said decorative design surface of said surface layer portion is exposed to the inside of the compartment of the automotive vehicle.
