Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mall structure of an indicator instrument suitable for application to a combination meter integrally incorporating various instruments such as a speedometer and a fuel gauge provided on a console panel of an automobile.

[0002]

[Prior art]

 Conventionally, as a combination meter in which various instruments such as a speedometer and a fuel gauge which are attached to a console panel of an automobile are integrally incorporated, those shown in FIGS. 2 to 4 are known. In this combination meter, a tachometer (tachometer) 2, a speedometer 3, a water temperature gauge 4 and a fuel gauge 5 are integrally incorporated into one instrument body 1 to guide light emitted from the lamps 6a to 6c. A voltmeter 16 that guides the design portion A and the pointers 12 to 15 displayed on the dials 8 to 11 of the respective meters by the light plates 7a to 7c, illuminates them through, and displays the battery voltage on the water temperature gauge 4. In addition, the fuel gauge 5 is integrated with a display device 17 for displaying an automatic shift pattern. A wind plate 18 is attached to the front surface of the instrument main body 1, and a wind plate 18 A transparent glass 19 is attached to the front surface. A molding portion (shaded portion in FIG. 1) 20 and a groove 21 for improving the parting of the molding portion 20 are formed along the inner edge of the molding portion 20 at the left and right edges and the lower edge of the glass 19. . The molding portion 20 is coated with black to form a non-translucent portion. At the time of coating, the edge of the masking coating jig 22 is inserted into the groove 21 to cover the transparent portion 19a of the glass 19 and black paint is sprayed on the molding portion 20.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional molding structure, the groove 21 can prevent the coating material from wrapping around the glass transparent portion 19a at the time of coating, but at the time of night illumination, it penetrates through the design portion A of the dials 8 to 11. A part of the illumination light and the illumination light of the pointer travels while reflecting inside the plate thickness of the glass 19 and is emitted to the outside as the direct light 23 from the groove 21 of the paint parting portion, which is not the original design. Nevertheless, there was a problem that it looked like a single line (edge shape). There is also a problem in that the bright range of the groove 21 changes depending on the pointing position of the pointers 12 to 15, and the appearance is poor.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to determine whether the parting groove portion is illuminated by the illumination light like an edge or the groove is bright. The purpose of the present invention is to provide a molding part structure of an indicating instrument which improves the appearance of the molding part without being changed by

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention comprises forming a mold part on the surface of the glass covering the front of the instrument main body by painting and forming a groove for partitioning the painting. Is chamfered to form a curved surface, and the inner wall surface of the groove from the starting point position of this curved surface to the bottom surface of the groove is formed as a diffusion surface.

[0006]

[Action]

 In the present invention, the inner wall surface of the parting groove of the molding part is a diffusion surface, and diffuses the illumination light that travels within the thickness of the glass plate and exits from the groove, and changes the edge-like direct light into a strip shape. , Reduce the amount of light entering the eyes.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. 1 (a) and 1 (b) are a cross-sectional view and an enlarged cross-sectional view of an essential part showing an embodiment of a molding part structure of an indicating instrument according to the present invention. In the figure, the same components as those in FIGS. 2 to 4 are designated by the same reference numerals, and the description thereof will be omitted. In the figure, in the present embodiment, the open end of the coating parting groove 21 formed along the molding portion 20 is chamfered with a radius R as appropriate to form a curved surface 24. From the starting point a of the curved surface 24, The inner wall surface of the groove, which reaches the bottom surface b of the groove, is textured to form a diffusion surface 25. Other configurations are the same as the conventional structure described above.

Thus, in the molding part structure having such a structure, the light 23 reflected from the glass 19 and traveling from the parting groove 21 is diffusely reflected and diffused by the diffusing surface 25, so that the light shines like an edge. The existing light becomes a band-shaped light, which reduces the amount of light entering the eyes. Further, because of the diffusion surface 25, the difference in brightness is reduced, the change in brightness depending on the position of the pointer is inconspicuous, and the appearance of the molding portion 20 can be improved.

[0009]

[Effect of device]

 As described above, in the molding part structure of the indicating instrument according to the present invention, a curved surface is provided at the open end of the coating parting groove, and the inner wall surface of the groove from the starting point of this curved surface to the groove bottom is used as the diffusion surface. Since it is configured to diffuse the light emitted from the groove as it travels inside the glass, the brightness of the light emitted from the groove is reduced, and the difference in light and shade depending on the amount of light entering the eye and the pointer position can be reduced. The design of the molding part can be improved.
