Definitions

  • the invention relates to the field of mechanical watchmaking. It relates, more particularly, to an adjustment system for a watch display mechanism for adjusting the position of a means for displaying information that the display mechanism comprises.
  • Clock displays are sometimes made by a roller display because the indications in this form are easily readable.
  • the invention aims in particular to overcome the various drawbacks of the prior art.
  • the invention also aims to provide an adjustment system allowing simple, rapid and precise adjustment of the display means without having access to the axis supporting the display means.
  • the invention also relates to a watch movement and a timepiece comprising a friction system according to the invention.
  • a friction system 100 according to the invention is shown.
  • This system comprises an axis 1 arranged to be mounted in a clockwork movement, the axis may comprise parts with sections 10, 11 of different diameters
  • FIG. 2 illustrates an adjustment system 1 for a display mechanism 100 of a timepiece according to one embodiment of the invention.
  • the display mechanism 100 may for example be a mechanism for displaying the time, date, day, date or even the moon phase of the timepiece.
  • the adjustment system for a display mechanism comprises in particular a wheel 1 arranged to pivot with a shaft 2, the wheel having a peripheral part 10 delimiting a central opening 11 of circular shape to receive the shaft 2. It will also be noted that the peripheral part 10 supports means for displaying information 3 which are integral with the peripheral part 10 of the wheel 1.
  • the wheel comprises friction means which have a friction portion at the central opening 11, the friction portion comprising friction zones 12, 13 around the shaft 2 to hold the wheel on the shaft.
  • the friction means also comprise at least two elastically deformable arms 4, 5, the arms connecting the friction portion to the peripheral part 10 of the wheel 1 to pinch the shaft 2 and prevent rotation of the wheel 1 around the shaft 2 below a predefined torque.
  • the wheel 1, the friction portion and the elastically deformable arms 4, 5 are advantageously in the form of a single-piece component.
  • the elastically deformable arms 4, 5 each comprise two opposite ends by which they are connected to the wheel 1. Such a connection allows optimal transmission of forces and stresses between these two elements, whether traction, compression, bending, torsion or shear.
  • the wheel 1 comprises a first elastically deformable arm 4 and a second elastically deformable arm 5 extending substantially parallel to the first arm, inside the wheel, and on either side of the central opening 11.
  • the two elastically deformable arms 4, 5 are intended to extend on either side of the shaft 2 arranged to drive the wheel 1 in rotation, and together form a clamping means capable of clamping a radial bearing surface of the shaft 2, the friction portion having an arcuate shape to optimize the friction surface with the shaft 2.
  • the friction portion may have a thickness greater than the thickness of the arms 4, 5 and of the peripheral part of the wheel to increase the contact surface with the shaft 2 and thus increase the friction surface.
  • the means for clamping the shaft 2 could comprise a greater number of elastically deformable arms.
  • it could comprise four arms arranged around the shaft 2.
  • the wheel 1 comprises fixing means 30 arranged near the peripheral part 10 to secure the means for displaying information on the wheel 1.
  • the wheel 1 also comprises stops 14, 15 to obtain good positioning of the display means 3 relative to the fixing means.
  • display means in the form of a scroll
  • other display shapes may be envisaged such as a hexagonal or octagonal shape for example.
  • Such an adjustment system thus makes it possible to adjust the position of information display means, such as rollers, axially to ensure alignment of the information displayed and radially to equalize the clearances between two information display means.
