Abstract
In an indicating instrument (1) with a translucent dial (8), an illuminated pointer (4) is arranged, out of the viewing direction of a viewer, behind the dial (8) on its rear, inner side (7). An additional covering glass for protecting the pointer (4) can thus be dispensed with.
Claims27
An indicating instrument, in particular for a vehicle, having a pointer, which is connected fixed in terms of rotation to a pointer shaft and can be driven by the pointer shaft, a pointer illumination and a dial, the dial having a scale for representing a value of a variable shown by the pointer, wherein the dial (8, 16) is translucent, and wherein the pointer (4) is arranged on the opposite side of the dial (4) from a viewer.
The indicating instrument as claimed in one of the preceding claims, wherein the surface of the outer side (9) of the dial (8, 16) is dull.
The indicating instrument as claimed in one of the preceding claims, wherein the dial (8, 16) is an opal plate.
The indicating instrument as claimed in one of the preceding claims, wherein the dial (8, 16) has a scale (13, 20) which is arranged on the opposite side of the dial (8, 16) from the viewer.
The indicating instrument as claimed in one of the preceding claims, wherein the pointer illumination has a light source (40) which is connected fixed in terms of rotation to the pointer (41).
The indicating instrument as claimed in one of the preceding claims, wherein the pointer (4) has a means for projecting onto a region of the dial (8) the light beams (14) which are emitted by the light source (2).
The indicating instrument as claimed in one of the preceding claims, wherein the dial (8, 16) has an optical transparency which is suitable for reading the unilluminated pointer (4, 41).
The indicating instrument as claimed in one of the preceding claims, wherein the indicating instrument is a combination instrument (43) having at least two displays (1, 21, 23).
The indicating instrument as claimed in one of the preceding claims, wherein the indicating instrument (1, 43) is inclined downward with respect to the vertical in the direction of a viewer.
The indicating instrument as claimed in one of the preceding claims, wherein the scale (13, 20) is translucent.
The indicating instrument as claimed in one of the preceding claims, wherein the main area (44) of the dial (16) is of a first color and the scale (20) is of a second color, the main area (44) of the dial (16) having a low transmission level when illuminated with light of the color of the scale (20).
The indicating instrument as claimed in one of the preceding claims, wherein the dial (16) has, in its regions outside displays (1, 21, 23), a masked area (45) with a low transmission level.
The indicating instrument as claimed in one of the preceding claims, wherein the dial (8, 16) has a scratch-resistant coating on its outer side (9) facing the viewer.
