Abstract
A timepiece display mechanism for a watch includes a roller pivoting about a main axis and including flaps, each pivoting about a secondary axis parallel to the main axis and having two faces, a first driver for pivoting the roller about the main axis, and a second driver for pivoting a flap about its secondary axis, in a determined position of this secondary axis relative to the main axis, and which include, at each flap, a drive pinion cooperating with a controller to modify, in sequence or continuously, the position of the successive flaps of the same roller or to modify, on demand, the position of a specific flap.
Claims14
A timepiece display mechanism comprising:
- at least one roller pivoting about a roller axis, said roller comprising at least one flap pivoting about a flap axis parallel to said roller axis and distinct from said roller axis, said at least one flap comprising at least one first face and at least one second face;
- first drive means for pivoting said roller about said roller axis;
- second drive means distinct from said first drive means for pivoting at least one said flap about said respective flap axis, in at least one determined position of said flap axis relative to said roller axis,
- wherein said second drive means comprise, at each said flap, at least one flap drive pinion centred on each said flap axis and arranged to cooperate with a control means, comprised in said display mechanism, to modify, on demand, the position of said at least one flap or when said at least one flap is a plurality of flaps, to modify, in sequence or continuously, the position of said successive flaps of said at least one roller.
