Configured. The design member 1 is entirely curved according to the interior of the automobile, and has an opening 1a formed in a part thereof, so that the interior part can be exposed to the outside through the opening 1a.

  The resin plate 2 is made of a transparent or translucent resin member, and in the present embodiment, is made of an acrylic plate. The surface 2a of the resin plate member 2 is in a state of facing the outside when assembled in an automobile, and a colored layer 3 is formed on the back surface 2b. The colored layer 3 is made of an opaque film. In the present embodiment, the colored layer 3 is made of a black thin film. Specifically, the colored layer 3 is formed by applying an adhesive or a solvent over the entire back surface 2b of the resin plate member 2 and adhering a film to the back surface 2b.

  The predetermined portion A is a portion that forms the design of the design member 1 and is configured by cutting the colored layer 3 into a predetermined shape. As shown in FIG. 1, the predetermined portion A according to the present embodiment has a star shape (predetermined shape) formed in the approximate center of the resin plate material 2, and the colored layer 3 on the back surface 2 b of the resin plate material 2. It is considered as an area where cutting is performed. In addition, the site | part B inside the predetermined site | part A is the state in which the colored layer 3 was not cut and the black film remained.

  Here, the predetermined part A according to the present embodiment is formed by laser processing in which the rear surface 2b of the resin plate material 2 is irradiated with a laser along a predetermined shape to cut the colored layer 3. Specifically, numerical data based on a desired predetermined shape is input to a terminal such as a personal computer (PC), the laser irradiation unit is operated according to the numerical data, and the colored layer is irradiated with the laser irradiated from the laser irradiation unit. By using a laser processing machine that cuts 3 into a predetermined shape, the predetermined part A is cut.

  Thus, a laser is irradiated along the predetermined portion A, and the film in the predetermined portion A is cut into a star shape to obtain the star-shaped design. In the present embodiment, as shown in FIG. 8, when the colored layer 3 in the predetermined portion A is cut, the back surface 2b of the resin plate 2 in the predetermined portion A is also cut by a predetermined dimension in the thickness direction. Although it is processed, only the colored layer 3 may be cut by arbitrarily changing the setting of a laser processing machine that performs laser processing. Moreover, in this embodiment, although it cut into the star shape, as long as it is the predetermined shape based on arbitrary designs, any shape may be sufficient.

Specifically, the coating part 4 is formed in the predetermined part A by applying a colored paint of a desired color to the predetermined part A on the back surface 2 a of the resin plate material 2. The application part 4 may be any of an opaque color that does not transmit light and a translucent color that transmits light, as long as the color is not the color (black) of the colored layer 3.

Next, the manufacturing method of the design member 1 according to the above embodiment will be described based on the flowchart of FIG.
First, a colored layer forming step S1 for forming an opaque colored layer 3 on the back surface 2b of the transparent or translucent resin plate material 2 is performed. In the colored layer forming step S1, as shown in FIG. 4 (a), a resin plate material 2 having a predetermined size and a black film (opaque film) constituting the colored layer 3 are prepared and made of resin. A predetermined adhesive or solvent is applied to the back surface 2b of the plate member 2, and after the film is brought into close contact with the back surface 2b of the resin plate member 2, as shown in FIG. Both are adhered by solidifying.

  Thereafter, a molding step S2 is performed in which the resin plate material 2 on which the colored layer 3 is formed is molded into a desired shape. In this molding step S2, as shown in FIGS. 5A to 5D, the resin plate material 2 is installed in a vacuum molding machine. As shown in the figure, the vacuum forming machine includes a main body F in which a sealed space is formed, a heater H capable of heating the resin plate member 2 installed on the upper portion of the main body F, and a main body. Blow bubble V capable of introducing air into part F, molding die K having an outer contour corresponding to a desired shape, and vacuum capable of sucking air through through-hole Ka formed in molding die K And means D.

  And as shown to the figure (a), while installing the resin-made board | plate material 2 (The state which orient | assigned the colored layer 3 below) to the upper part of the main-body part F, the said resin-made board | plate material 2 is heated with the heater H. After being softened by this, the blow valve V is opened to introduce air into the main body F and the resin plate material 2 is expanded and deformed as shown in FIG. Thereafter, as shown in FIG. 3C, the mold K is raised to press the mold K against the resin plate 2 and the surface of the mold K and the resin plate 2 by the vacuum means D. The air between the back surface (colored layer 3) is sucked (vacuum forming).

  By undergoing such vacuum forming, the outer contour of the forming die K is accurately transferred to the resin plate material 2, so that the resin plate material 2 is formed into a desired shape. Then, after the resin plate material 2 is cooled and hardened, as shown in FIG. 6D, when the mold K is lowered to the initial position and the resin plate material 2 is taken out from the main body F, FIG. 7, a resin plate 2 molded into a desired shape (specifically, curved in the vertical direction) can be obtained. In the present embodiment, a cutting process for forming the opening 1a is performed after molding or before molding.

  Next, a cutting step S3 for cutting the predetermined portion A of the colored layer 3 formed in the colored layer forming step S1 into a predetermined shape is performed. In this cutting step S3, as described above, the laser beam from the laser processing machine is irradiated along the predetermined portion A of the colored layer 3, thereby forming the colored layer 3 at the predetermined portion A as shown in FIG. It is supposed to be removed by cutting. In addition, although cutting of the predetermined part A is made into the smooth surface over the said predetermined part A whole, you may cut roughly and you may make it frosted glass.

  Finally, a coloring step S4 for performing desired coloring different from the colored layer 3 on the predetermined portion A cut in the cutting step S3 is performed. In the coloring step S4, as described above, a colored paint of a desired color (color other than the colored layer 3) is applied to the predetermined portion A on the back surface 2b of the resin plate material 2 to form the application portion 4. It is supposed to be. Thereby, the predetermined site | part A colored by the desired color can be visually recognized from the surface 2a side of the resin-made board | plate materials 2, The predetermined site | part A of the said arbitrary shape can be functioned as a design.
