Definitions

  • the present invention relates to an oscillating winding mass provided with a rotary element for the automatic movement of a timepiece. More particularly, the invention relates to such a winding mass intended to equip a wristwatch comprising a transparent back. The invention also relates to a timepiece provided with such an oscillating winding mass.
  • Wristwatches are already known which have cases with a transparent bottom to allow their movement to be observed. However, when these watches have a self-winding movement, the oscillating winding mass hides a movement part.
  • the aesthetics of such oscillating masses are not always pleasant, even if it is possible to engrave the material forming the oscillating weight to make it more attractive. It is possible, for example, to engrave a decorative element, such as a logo representing the brand of the watch. But this logo is generally not visible enough for the result to be aesthetically convincing. In addition, a simple coloring of the logo is not enough to make the mass more aesthetic, not to mention that the color can degrade over time. In addition, the decorative element is static with respect to the rest of the oscillating weight.
  • the object of the present invention is to remedy the drawbacks of the prior art by proposing an oscillating winding mass for a timepiece comprising a particular decorative element.
  • the invention relates to an oscillating winding mass for a movement of a timepiece, said oscillating winding mass being intended to be mounted for rotation on an axis of the movement.
  • the invention is remarkable in that it comprises a main element and a decorative element, for example a logo or an acronym, a part of the winding mass forming a heavy part allowing the oscillation of the mass in response to the movement of the timepiece and the force of gravity, the main element giving the general shape of the oscillating winding mass, the decorative element being mechanically linked to the main element, the decorative element being rotatably mounted on the main element.
  • a decorative element for example a logo or an acronym
  • a decorative element is rotatably linked to the main element of the winding mass.
  • the winding mass has a more attractive aesthetic rendering than a conventional winding mass known from the state of the art.
  • the rotary decorative element which can represent a logo or an initials of a mark, gives more cachet to the winding mass and therefore to the timepiece.
  • the main element and the decorative element can rotate together at different speeds, or the decorative element can rotate when the main element has just stopped.
  • the rotation of the decorative element relative to the main element offers a particular aesthetic effect.
  • the heavy part is formed by at least part of the main element.
  • the mass comprises a ball bearing to allow the decorative element to rotate.
  • the ball bearing is arranged on the main element.
  • the main element comprises an opening in which the decorative element is arranged.
  • the ball bearing is arranged in an internal face of the opening.
  • the balls are arranged in the mass of the main element.
  • the balls are distributed angularly in the internal face of the opening.
  • each ball is retained in a housing whose dimensions allow the ball to rotate while being retained in a substantially predefined position.
  • the housing comprises an orifice opening into the opening, so that part of the ball projects from the housing into the opening so as to be able to be in contact with the decorative element.
  • the decorative element comprises a portion intended to be in contact with the balls of the bearing.
  • the decorative element comprises ceramic, preferably entirely.
  • the main element comprises amorphous metal.
  • the internal face of the opening comprises rails for retaining the decorative element in the opening, the portion of the decorative element preferably being of bevelled shape.
  • the invention also relates to a timepiece comprising a case formed of a middle part closed by a crystal and an at least partially transparent back and in which is housed a self-winding timepiece movement, said movement being equipped with 'an oscillating winding mass as defined above.
  • FIG. 1 We have represented on the figure 1 an embodiment of an oscillating winding mass according to the invention, designated by the general reference 1.
  • This mass 1 is intended to conventionally equip the automatic winding movement of a timepiece, the part comprising in particular a box formed of a middle part closed by a crystal and a back at least partially transparent to make the movement visible from the back, and which are not shown in the figures.
  • the winding mass 1 comprises a main element 2 giving the general shape of the oscillating winding mass 1.
  • the main element 2 comprises a heavy part 3 and a connecting member 5 intended to connect the heavy part 3 to an axis (not shown in the figures) integral with a clockwork movement, the mass 1 being intended to be mounted to rotate on this axis.
  • the heavy part 3 allows the oscillation of the mass 1 in response to the movement of the timepiece and to the force of gravity.
  • the connecting member comprises a substantially circular ring 4 and a substantially flat wall 5 connecting the ring 4 to the heavy part 3 of the mass 1.
  • the ring 4 is intended to be arranged on the axis of the movement.
  • the oscillating mass 1 performs a circular movement around the axis, when it oscillates.

  • the decorative element 10 is here an anchor-shaped logo having a substantially straight segment 11 and a curved segment 12, the straight segment 11 being connected to the curved segment 12 at its middle, on the inner side of the curvature.
  • the main element 2 has an opening 6 in which the decorative element 10 is arranged.
  • the opening 6 is made in the wall 5 of the connecting member in the plane of the wall 5.
  • the decorative element is arranged in the same plane as the opening 6 and the wall 5.
  • the opening 6 passes through the wall 5 of the main element 2.
  • the opening 6 here has a circular shape provided with a center of the circle.
  • the opening 6 is bordered by an internal face 7 defining the outline of the opening 6.
  • the internal face 7 has a cylindrical shape, the height of which corresponds to the thickness of the wall 5.
  • the decorative element 10 is rotatably mounted on the main element 2.
  • the winding mass 1 comprises a ball bearing 8 9.
  • the ball bearing 8 9 is arranged on the main element 2 to allow the decorative element 10 to rotate by sliding on the balls 9.
  • the ball bearing 8 9 is arranged in the opening 6, in the internal face 7.
  • the decorative element 10 can then rotate about an axis passing substantially through the center of the opening 6.
