Abstract (en)
[origin: JP2019158878A] To provide a regulated jumping display mechanism for timepieces.SOLUTION: A timepiece display mechanism 1 includes a barrel 10 with a spring between an arbor 41 of a first wheel set 4 driven by a drive wheel set 201, and a drum 3 carrying a peripheral snail 51 cam 5. The cam 5 is traversed by a feeler 6 controlling periodic jumps of a display member 100. This drum 3 carries a peripheral finger 7 outside a trajectory of this feeler 6. The first wheel set 4 includes an eccentric crank pin 42. The eccentric crank pin 42 permanently guides a groove 81 to control periodic back and forth motions of a pivoting anchor piece 8. The anchor piece 8 includes, on either side of an anchor piece axis D8, a beak 83 and a stop 84 for stopping or releasing this finger 7 depending on the angular position of this anchor piece 8. The angular travel of each finger 7 between release of the finger 7 by the beak 83 and return of the finger 7 to abutment on this stop 84 defining the jump duration.SELECTED DRAWING: Figure 1
