Abstract
A mechanism (3) for indicating and storing time information, including a transmission device (7) coupling a time information counting system (5) and a member (S′) for displaying time information adapted to display selectively current time information and stored time information, including: a cam (C); a lever device (L) including a lever (L1), a follower (L2) and a first elastic member (R) urging the lever and the follower into a particular relative position; the lever (L1) being kinematically coupled to the display member (S′) for displaying time information, the follower (L2) being urged against the cam (C) by a second elastic member (RL).
Claims23
A mechanism for indicating and storing time information, including a transmission device coupling a time information counting system and a first display member for displaying time information adapted to display selectively current time information and stored time information, the mechanism including:
- a cam;
- and
- a lever device including a lever, a follower and a first elastic member urging the lever and the follower into a particular relative position;
- wherein the lever is kinematically coupled to the first display member for displaying time information,
- wherein the follower is urged against the cam by a second elastic member, and
- wherein the mechanism is adapted to immobilize the lever, so as to display the stored time information,
- wherein the stored time information is defined by an instantaneous position of the lever at an instant of immobilization, and
- wherein the lever device allows the follower to maintain cooperation with the cam during immobilization, without affecting a position of the first display member.
