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.

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.

After processing, since the desired color different from the colored layer 3 was given to the predetermined part A, the predetermined part A with the desired coloration functions as a design and the visual recognition of the predetermined part A is improved. It is possible to improve the design properties. In addition, according to the design member 1 which concerns on this embodiment, since processing, such as cutting and coloring, is not given with respect to the surface 2a of the resin-made board | plate materials 2, smoothness can be maintained and design property is maintained. Further improvement can be achieved.

  Moreover, according to this embodiment, since the cutting process in the cutting process S3 is a laser process in which the colored layer 3 is cut by irradiating a laser along a predetermined shape, the design member 1 having a small lot design is used. Even if it exists, while being able to respond | correspond easily, cutting of a predetermined part can be performed more accurately and smoothly.

  Moreover, in the said embodiment, although the cutting process in cutting process S3 is made into laser processing, if it is the processing method which cuts the predetermined site | part of a colored layer into a predetermined shape, the other general purpose using a cutting blade A cutting method may be used. In addition, the laser processing machine for laser processing can use the thing of various forms, an operator has a laser irradiation means by hand, and cuts the colored layer in the predetermined part of a desired shape by hand. It may be a thing. And the character of a nameplate (in this embodiment, the character "Kobayashi") can be visually recognized from the surface 6a of the resin member 6.

  Furthermore, in the molding step according to the above embodiment, when molding into a desired shape, the resin plate material while pressing the molding die K corresponding to the desired shape against the resin plate material 2 on which the colored layer 3 is formed. Although a molding method (vacuum molding) that sucks air between the mold 2 and the molding die K is employed, other general-purpose molding methods that can be molded into a desired shape may be used. In the above-described embodiment, the resin plate material is formed into a desired shape by passing through the forming step S2. However, a plate-shaped design member may be used without passing through the forming step S2.

  Further, the colored layer according to the above embodiment is formed by adhering an opaque film to the back surface of the resin plate material. However, if an opaque colored layer can be formed, an opaque paint may be applied. Good. Further, the color of the colored layer is not limited to black as in the above embodiment, and can be any color.
