Description

  The present invention relates to a pointer for an instrument device mounted on a moving body such as an automobile, and more particularly, to a pointer for an instrument device that allows an observer to visually recognize the pointer body by shining.

  A moving body such as an automobile or a ship is equipped with an instrument device for displaying information measured by various measuring means to passengers of the moving body. Among such instrument devices, an analog instrument device using a pointer includes a type in which the pointer is shined by light from a light source (see, for example, Patent Document 1).

  The pointer of this type of instrument device is formed from a light guiding material. The pointer includes a base end portion serving as a rotation center, an instruction portion extending from the base end portion in the outer peripheral direction of the base end portion, and a light receiving portion provided at the base end portion. In the pointer, the light receiving unit receives light from the light source and reflects the light toward the pointing unit so that the pointing unit shines uniformly. Since the pointer is brilliant in a single color, there was room for improvement so that it would stand out from the surroundings and draw the attention of the occupant of the moving object.

  In order to solve this type of problem, various measuring device guidelines are used (see, for example, Patent Document 2). In this type of pointer, the indicating unit is configured such that a plurality of light guide members arranged in the width direction of the indicating unit and light guided in each light guide member enter the other light guide members adjacent to each other. And a blocking means for blocking.

When the light from the light source enters one light guide member, the light does not enter another light guide member adjacent to the light guide member. Therefore, only the inside of the light guide member which entered first can pass, and only a desired light guide member can be made to shine. In addition, by changing the light color of the light source and the timing at which the light source shines for each light guide member, the plurality of light guide members can be lit with different colors and timing. The pointer is more prominent from the surroundings, and the point of indication becomes clear, so that the visibility of the occupant of the moving body can be improved.

  Further, a protrusion 49 is provided on the inner surface of the bottom wall 18 c facing the back surface 38 of the instruction unit 14. The protrusion 49 is provided in the center of the inner surface of the bottom wall 18 c of the cover 19 over the entire length of the cover 19. The protrusions 49 are provided along the longitudinal direction of the cover part 19 at intervals from both ends of the cover part 19 in the width direction. The protrusion 49 engages with the recess 48 of the instruction unit 14.

  In the present embodiment, a concave portion 48 is provided in the concave portion from the central portion of the back surface 38 facing the dial 6 of the indicating portion 14 and is provided over the entire length of the indicating portion 14, and a colored layer is formed on the inner surface of the concave portion 48. 40 is provided. For this reason, the colored layer 40 may be provided according to the size and shape such as the position and width of the recess 48. Therefore, the colored layer 40 can be easily provided at a desired position, size and shape.

  In the first and second embodiments described above, the reflective layer 16 is provided on the inner surface of the cover portion 19. However, in the present invention, as shown in FIG. 7, the reflective layer 16 may be provided on the outer surface of the pointing portion 14 of the pointer main body 21. In this case, the cover member 19 may not be provided on the base member 20.

  In the first and second embodiments described above, the colored layer 40 is provided in the instruction unit 14. However, in the present invention, as shown in FIG. 8, the colored layer 40 may be provided on the inner surface of the cover portion 19.

  In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.
