Abstract
The invention relates to an indicator apparatus (1) having a ring pointer (2), which is mounted such that it can move in the circumferential direction (5), and having a drive unit (3), which drives the ring pointer (2) in the circumferential direction (5), wherein the ring pointer (2) interacts with a stop (10) in a manner limited in terms of its circumferential movement. Particularly in the case of synchronization, radial disengagement often occurs in conventional ring pointer arrangements, and the aim of the invention is to prevent this. In order to solve the problem, the invention proposes arranging the stop (10) directly next to the drive unit (3). The critical advantage of this is that the tangential force on the ring pointer (2) from the drive unit generates an only small disengagement moment on the ring pointer (2).
Claims7
An indicator apparatus, comprising:
- a ring pointer having a stop face, said ring pointer comprising one of a ring and annular segment and being movably mounted such that the ring pointer is movable in a circumferential direction relative to the indicator apparatus;
- a drive unit which drives the ring pointer in the circumferential direction relative to the indicator apparatus;
- and
- a stop arranged proximate the drive unit which interacts with the stop face to limit the circumferential movement of the ring pointer.
Dependencies are inferred from the claim text.
