Pointer instrument having a double pointer and an eccentrically arranged fastening column
View Patent ↗A pointer instrument, in particular in a motor vehicle, including a central indicating unit arranged on a fastening column. The fastening column is arranged outside of the center of the indicating unit, an indicating surface concentrically surrounding the indicating unit, and a centrally supported first pointer for visibly pivoting over the indicating surface. The indicating unit is arranged in front of the pointer and outside of the view of the observer. A second pointer, which has an opening for surrounding the fastening column, is arranged concentrically to the first pointer.
1. A pointer instrument comprising:
a central indicating unit;
a fastening column on which the central indicating unit is arranged, wherein the fastening column is arranged outside of a center of the central indicating unit;
an indicating surface concentrically surrounding the indicating unit;
a centrally supported first pointer configured to visibly pivot over the indicating surface, wherein the central indicating unit is arranged in front of the centrally supported first pointer from a viewpoint of an observer; and
a second pointer is arranged concentrically with respect to the first pointer and defines a recess that surrounds the fastening column,
wherein the recess is formed by a ring segment connected to a pointer bushing by at least one web.
2. The pointer instrument as claimed in claim 1 , wherein the ring segment extends through 360°.
3. The pointer instrument as claimed in claim 1 , wherein the ring segment extends through 180°.
4. The pointer instrument as claimed in claim 1 , wherein the ring segment extends through 90°.
5. The pointer instrument as claimed in claim 1 , wherein the ring segment is arranged behind the indicating unit from the viewpoint of the observer.
6. The pointer instrument as claimed in claim 5 , wherein the ring segment is hidden by the indicating unit from the viewpoint of the observer.
7. The pointer instrument as claimed in claim 1 , wherein the ring segment is formed in one piece with the pointer bushing.
8. The pointer instrument as claimed in claim 7 , wherein the ring segment is formed in one piece with the pointer bushing from metal or plastic.
9. The pointer instrument as claimed in claim 1 , wherein a pointer tip of the second pointer is connected to the ring segment.
10. The pointer instrument as claimed in claim 9 , wherein the pointer tip is made from a light-guiding material.
11. The pointer instrument as claimed in claim 10 , wherein the pointer tip comprises:
a coupling-in surface on a side directed toward the ring segment,
a coupling-out surface of a light-guiding element is arranged opposite the coupling-in surface,
wherein the coupling-out surface extends along a trajectory of the coupling-in surface, and
the light-guiding element has at least one coupling-in surface configured to receive light from at least one light source, such that the light from the light source can be guided by the light-guiding element into the pointer tip to illuminate the latter.
12. The pointer instrument as claimed in claim 9 , wherein the pointer tip is made from a plastic.
13. The pointer instrument as claimed in claim 12 , wherein the plastic is PC or PMMA.
14. The pointer instrument as claimed in claim 1 , wherein the ring segment is connected to a pointer bushing by at least two webs.
15. The pointer instrument as claimed in claim 1 , wherein the ring segment is connected to a pointer bushing by at least three webs.
