Abstract
A mechanism for correcting a device for displaying time information is described. The display device includes a first display member for displaying current time information and a second display member for displaying stored time information, notably a second display member of the retrograde type. The mechanism includes an isolating device for isolating the first and second display members.
Claims22
A mechanism for correcting a display device for displaying time information, the display device comprising a first display member for displaying current time information, and a second display member for displaying stored time information, the mechanism comprising:
- an isolating device for isolating the first and second display members,
- a correction element, wherein the correction element is adapted to correct a time information, and
- a drive member,
- wherein each of the correction element and the drive member actuates the isolating device, so as to isolate the first and second display members from each other.
A mechanism for correcting a display device for displaying time information, the display device comprising a first display member for displaying current time information, and a second display member for displaying stored time information, the mechanism comprising:
- an isolating device for isolating the first and second display members,
- wherein the isolating device comprises an isolating lever capable of acting on a pivoted lever device,
- wherein the lever device comprises a lever, a follower and a first elastic member returning the lever and the follower to a particular relative position, the lever being kinematically linked to the second display member,
- wherein the isolating device acts on the follower, for selectively positioning the first and second display members in a first configuration and in a second configuration,
- wherein in the first configuration, the isolating device releases the follower, so that the follower is pressed against a cam connected to the first display member under the effect of a second elastic member, and
- wherein in the second configuration, the isolating device acts on the follower, so that the follower is disconnected from the cam or kept away from the cam.
