Definitions

  • the present invention relates to an automatic winding device for recharging the energy source of a portable apparatus by means of an oscillating mechanism driven by the movements of the wearer.
  • the "portable" device will be illustrated by a horlvgerie piece, and more particularly by a wristwatch.
  • the energy source will be more particularly illustrated by a source of mechanical energy, such as a cylinder whose spring will be reassembled to cause the display of the current time, a striking mechanism, or any other complication in a movement mechanical watchmaker.
  • the energy source can also be a source of electrical energy such as a capacity recharged by a dynamo driven by the oscillating mechanism.
  • Patent CH 329 806 describes such a mechanism in which the balls are held between the teeth of a pivoted rake in the center of the box, that is to say with the same disadvantages as those mentioned above.
  • the balls which occupy about 1/5 of the raceway, directly drive the branches of a star which is the first mobile of the kinematic chain connected to the barrel.
  • they are preferably grouped in rolling cages, which increases the rigidity of the mechanism and still requires the winding stem located at the bottom of the box.
  • it is also expected to have more than one star which obviously increases the complexity of the drive train to the cylinder.
  • the present invention therefore aims to overcome the drawbacks of the aforementioned prior art by providing an automatic ball winding device for recharging the source of mechanical or electrical energy of a portable device, and in particular a wristwatch, which is easily adaptable to any type of caliber without increasing the thickness or having to change the position of the winding stem, while having a quiet operation, and not masking the movement or the display.
  • the invention relates to an automatic winding device for recharging the energy source of a timepiece
  • a dial provided with a central display module
  • said device being formed by an oscillating mass constituted by a set of balls circulating freely in a curvilinear raceway by driving a star which constitutes the first wheel of a winding kinematic chain.
  • the device is characterized in that the set of balls form a continuous train occupying the entire path of the bearing being constituted by a first subset formed of heavy balls made of a high density material and by a second subset formed light beads made of a lower density material, the distribution of heavy balls and light beads not being repetitive.
  • the heavy and light balls form a continuous train, so that shocks and the resulting noise are in principle excluded.
  • FIGS 1 and 2 there is shown by way of example an automatic winding device for mounting in a circular mechanical watch case whose central display is symbolized by the hour hands and of minutes 20.
  • the watch movement as such, and its possible complications are not part of the invention and are not represented, with the exception of the barrel 1 which constitutes the source of 'energy mechanics of the movement on which will act the device to refit the spring contained in the barrel box.
  • the rolling path of the device comprises an annular base 16 comprising, near the inner edge, a groove 16a having a cross-section in a circular arc and a circular closure ring 18 also having a groove 18a near its inner edge.
  • annular base 16 and the closure ring 18 are assembled by screws 19 (not shown in Figure 1) and form a raceway 10 having at least one opening 10a inward at the junction of the base 16 and of the ring 18.
  • the raceway 10 is entirely occupied by a set of balls 12, 14 with a virtual pivot point located in the center of the watch.
  • These balls are distributed between a first subset of heavy balls 12 forming a continuous train and a second subset of lighter balls 14 forming another continuous train.
  • the number of heavy balls 12 and light balls 14 is substantially the same and the raceway 10 is entirely located in a plane parallel to the plane of the watch.
  • the heavy balls 12 are made of non-magnetic metal or alloy, such as an alloy of platinum and iridium having a density of between 21 and 22g / cm 3 .
  • Light beads 14 are for example made of a material of organic or synthetic origin having a density of the order of 0.9g / cm 3 , so that the density ratio between the light and heavy beads is of the order of 1/20.
  • the light balls 12 could also be constituted by hollow metal spheres.
  • the center of gravity of the set of balls is distinct from the virtual pivot point so that any movement printed on the device will circulate said balls 12, 14 in the raceway 10 and drive the first mobile of the connecting kinematic chain.
  • the ratchet 1a This first mobile is constituted by a star 2 whose branches 2a are distributed so that they can be interposed in the space formed between two balls, whether heavy balls 12 or light beads 14, so that any movement of the wearer causes the rotation of the star 2, which works in some way to 100%.
  • the kinematic chain represented corresponds to a two-way mechanism with movable clutch. It is also possible, without departing from the scope of the invention, to interpose between the star 2 and the ratchet 1a another winding mechanism in one direction, to achieve a relatively simpler mechanism and occupying a smaller space to enhance the other motives of the watch movement in a skeleton watch.
  • the driving star 2 corresponds to the first clutch wheel and comprises a first clutch ratchet 4 having a teeth in wolf teeth in which can snap oscillating pawls 3 pivoted on the clutch.
  • the first clutch ratchet 4 comprises oscillating pawls (ref.3) which work with a ratchet (ref.4) integral with a pinion 4a which meshes with the first wheel 5 of the reduction gear train.
  • the pinion 5a of this first wheel 5 meshes in turn with a second wheel 6 of the gear train.
  • the pinion 6a of this second wheel 6 finally meshes with a second clutch wheel 7 on which are pivoted pawls 8 whose jaws are engaged in the teeth of a wolf teeth of a second clutch ratchet 9, which the pinion 9a meshes with the ratchet 1a.
  • This second device allows, if necessary manual winding ratchet 1, without rotating all the cog in the system.
  • the operation of this kinematic chain is well known to those skilled in the art and will not be described further. All these mobiles are pivoted between a bottom plate 11, held in the annular base 16 by the screw heads 13, and intermediate bridges 15a, 15b, 15c.
  • Figure 4 shows another embodiment which differs from that previously described in that the raceway 10 has an oval shape.
  • the balls 12, 14 which have no mechanical connection between them can move unhindered in this non-circular raceway.
  • a light bead train 14 has also been represented which is longer than the heavy bale train 12.
  • FIG. 5 which is a section along the line VV of FIG. 1, represents another embodiment in which a portion 10b of the raceway 10 forms a curve deviating from a plane parallel to the watch, for example to leave a passage 17 at a time setting rod.
  • the automatic winding device that has just been described can be adapted by those skilled in the art, without departing from the scope of the invention, to any type of housing in which it is possible to form or insert a path curvilinear rolling to go up either a spring mechanical mechanism, or a generator for charging a super-capacitance electric to power an electrical or electronic circuit.
  • a modification within the reach of those skilled in the art may for example consist of using the parts 16 and 18 of the raceway 10 to form the casing ring, or even the flange of the dial.
