Definitions

  • the present invention relates to automatic rotating or oscillating winding masses pivoted on the outside of a clockwork movement as well as self-winding watch movements equipped with such an oscillating or pivoting mass.
  • Such an oscillating weight of the document is known DE 10 2009 005 690 which comprises a circular ring whose inner edge is provided with a toothing intended to be kinematically connected to the ratchet of a barrel.
  • the upper face of this circular ring carries the winding mass itself which is in the form of a crown sector with an angular span preferably of 180 °.
  • Document is also known CH 458213 an oscillating mass intended to be pivoted by a ball bearing on the outside of a clockwork movement.
  • This mass also has the shape of an annular sector with an angular extent of the order of 180 °.
  • this embodiment suffers from the same defects previously stated in relation with the embodiment described in the document DE 10 2009 005 690 .
  • the object of the present invention is to allow the realization of a self-winding watch movement whose oscillating weight is rotated outside the movement can have a greater weight for a given size given by the diameter and the height of the movement. watchmaking to realize an automatic winding mechanism more powerful and effective than known devices.
  • Another object of the present invention is to provide, by the shape of the oscillating mass pivoted outside a clockwork movement, a visual and aesthetic effect of said movement that is new, fun and attractive.
  • the subject of the present invention is an oscillating mass intended to be pivoted on the outside of a watch movement comprising an annular frame and a central part situated, predominantly or exclusively, in one half of the surface delimited by the annular frame constituting an imbalance.
  • the present invention also relates to a watch movement, in particular a wristwatch, comprising an automatic winding mechanism equipped with such an oscillating weight.
  • the figure 1 illustrates in perspective a form of execution of an oscillating mass according to the invention fixed on the inner race of a ball bearing whose outer cage 2 is fixed on the peripheral part of the plate 3 of a watch movement , including a wristwatch.
  • This oscillating mass comprises an annular frame 4 intended to be fixed by screws 5 on the upper part of the inner race 1 of a ball bearing.
  • the annular frame 4 has a thicker part (and therefore heavier) and a thinner (and therefore lighter) part, and it is also provided with openings 6 in and along the thinner and lighter part.
  • the weight of the annular frame 4 is not uniformly distributed, and the annular frame therefore has an unbalance.
  • the unbalance effect can also be achieved by other means known to those skilled in the art - for example by using materials of different weights for the heavier and lighter parts respectively (either instead or in combination with the means described above).
  • This oscillating mass also comprises a central portion 7 located mainly or exclusively in the part of the surface defined by the heavier portion of the annular frame 4.
  • This central portion 7 is fixed at one or more points to the heavier portion of the annular frame 4
  • the central portion 7 is located mainly or exclusively in one half of the surface defined by the annular frame 4.
  • This central portion 7 of the oscillating mass can of course also come from a single workpiece with the frame outer ring 4.
  • the oscillating mass may have a large unbalance (which, preferably, adds to the unbalance of the frame 4), corresponding at least to the weight of the central portion 7 of the oscillating mass which ensures power and efficiency increased by the oscillating weight for the reassembly of an automatic winding mechanism of a clockwork movement.
  • the central portion of the oscillating mass may have any shape but preferably represents a figurine for example a panther in the illustrated variant.
  • the unbalance is much greater than an annular oscillating mass or annular sector as currently known.
  • the central portion 7 of the mass occupies at most half of the area defined by the annular frame 4 of the oscillating mass, but for some desired shapes of the central portion 7 the latter may extend into the other half provided that its unbalance effect is not significantly affected.
  • the frame of the mass may comprise an annular sector with an angular extent less than 360 ° (for example of the order of 180 °).
  • the weight of such a frame can be evenly distributed or it can be lighter towards its ends.
  • the central portion of the mass may be attached or bonded to this frame as described above.
  • the figures 2 and 3 illustrate schematically and partially a clockwork movement equipped with an oscillating mass as described above.
  • the outer race 2 of the ball bearing is fixed with screws 8 on the plate 3 of the clockwork movement.
  • the inner race 1 of the ball bearing comprises a cylindrical upper part 1a surrounding the dial 9 of the watch movement whose upper surface is situated in a plane parallel to the dial 9 but above the hands 10, 11 of the time display. of the watch movement.
  • the oscillating mass 4,7 is fixed by screws 5 on the cylindrical portion 1a of the inner race of the ball bearing so that the central portion 7 of the oscillating mass moves over the switch of the clockwork movement.
  • the central mass 7 of the oscillating mass is such that it does not interfere with the axis or the axes of the switch of the movement but moves over the dial and the switch.
  • the shape of the central portion 7 of the oscillating mass is preferably such that, whatever its angular position relative to the movement during its operation, the axis or axes of the switch of the time display of said movement is always out of the scanning area of this central portion 7 and thus of the oscillating mass 4,7.
  • the plane in which the oscillating mass 4,7 moves may be parallel to the dial 9 but located between said dial 9 and the hands 10,11.
  • the needles 10, 11 are in any time entirely visible to the user of the watch having such an oscillating weight for its automatic winding mechanism.
  • the dial can also be removed, as in a skeleton watch, and in this case the central portion of the mass would be located between the plate and the needles 10,11 in this variant.
  • the central portion (7) of the oscillating mass moves on the same side of the movement as the switch while not interfering with it.
  • a watch comprising a movement equipped with an oscillating mass according to the present invention allows an effective and powerful winding of its barrel on the one hand and on the other hand has a totally new aesthetic, original, fun and attractive.
  • the lower part of the inner ring 1 of the ball bearing has a toothing 1b engaged with a kinematic connection connecting it to the ratchet of a movement barrel in a manner well known to those skilled in the art.
