Definitions

  • the present invention relates to the field of watchmaking. It relates, more particularly, to an animation mechanism which comprises at least two decorative objects, the latter being able in particular to be astral representations.
  • the document FR2988866 describes a mechanism for animating a precious or semi-precious stone, in which a mainspring is arranged to animate the stone according to a rotational movement around a single axis of rotation by means of a flexible belt.
  • the stone is mounted on a shaft by four claws or jaws, which hold it in place.
  • the movement of the stone is monotonous and only reveals one of its faces, which always presents the same angle to the wearer and therefore limits its visibility.
  • the document CH708473 unveils an astral animation mechanism, which includes a rotating disk representing the earth as well as a larger diameter disk with an off-center circular opening defining a representation of the moon.
  • the representation of the earth rotates and that of the moon orbits around the earth.
  • An additional disc underlying that of the moon also makes it possible to display the phases of the moon. This mechanism is certainly interesting but is limited to a flat display.
  • the “GMT” coin marketed by Greubel Forsey presents a three-dimensional representation of the northern hemisphere of the earth, which rotates in front of a 24-hour scale. The visibility of this domed representation is relatively limited, especially when one wishes to see places near the equator, and where no representation of the moon is present.
  • the document CH707163 describes various variations of mechanisms, in which is shown a three-dimensional representation of the moon which orbits around an axis, on which a representation of the earth may be located.
  • the visibility of the moon representation is limited and the possibilities for other display variants are also relatively limited.
  • the object of the invention is therefore to provide an animation mechanism in which the aforementioned defects are at least partially overcome.
  • This mechanism comprises a support system carrying a first decorative object intended to be animated according to a rotation around a first axis of rotation and around of a second axis of rotation under the effect of a driving source, directly or indirectly.
  • the driving source can be mechanical or electrical, and can be dedicated to the mechanism or can be the one that provides the driving force for a timepiece.
  • Said support system comprises a first frame pivotally mounted on a frame member about said first axis of rotation, and an inner frame pivotally mounted in said first frame about said second axis of rotation which is substantially orthogonal to said first axis of rotation. rotation (that is to say that the inner frame is pivoted on the first frame, thus defining a gimbal system), said inner frame directly or indirectly bearing a second decorative object.
  • Said inner frame (and thus the first decorative object) is arranged to be driven by an eccentric drive element integral in rotation with a drive wheel set arranged to be driven directly or indirectly by said power source.
  • said first decorative object is carried by a shaft mounted to pivot in said inner frame about a third axis of rotation, said shaft being integral in rotation with a pinion meshing with a toothing which is coaxial with said drive wheel set, and which can be fixed or arranged to be rotated.
  • the first decorative object can thus pivot around its own axis of rotation.
  • said first decorative object is carried by an additional frame pivotally mounted around the third axis of rotation defined by the aforementioned shaft.
  • the additional frame is arranged to be driven in rotation via an intermediate transmission carried by the inner frame and arranged to be driven by a toothed member integral in rotation with said shaft.
  • the first decorative object can thus be arranged to pivot at a speed of rotation which is different to that of the shaft, if desired.
  • said eccentric drive element is a crank or a lever, which represents a solution that is relatively simple and easy to implement.
  • said second decorative object is arranged to perform an orbital movement around the first decorative object.
  • said second decorative object can be carried by a rotary board arranged to pivot around said third pivot axis.
  • said rotary plate is driven in rotation by means of a mobile unit pivotally mounted on said rotary plate and meshing on the one hand with a toothed member which is integral in rotation with the shaft, on the other hand with a additional fixed wheel integral in rotation with the inner frame.
  • a mobile unit pivotally mounted on said rotary plate and meshing on the one hand with a toothed member which is integral in rotation with the shaft, on the other hand with a additional fixed wheel integral in rotation with the inner frame.
  • said second decorative object is arranged to perform a rotation around its own axis, which gives the constructor a large number of possibilities in terms of animations.
  • said second decorative object is arranged to be able to move up and down relative to the plane of said inner frame. This makes it possible in particular to represent the fact that the orbit of the moon is not coplanar with the equator of the earth, or simply to animate another object in this way.
  • the mechanism further comprises a cover which surrounds part of the first decorative object, which is useful for illustrating, for example, the illuminated portion of the earth when the first decorative object is a representation of the sun and the second decorative object is a representation of the earth.
  • the pivoting cover is arranged to pivot around said second decorative object, which is useful for illustrating the phase of the moon or the like when the first decorative object is a representation of the earth and said second decorative object is a representation of the moon.
  • said pivoting cover can be integral in rotation with a mobile device arranged to be driven in rotation by means of a toothed member integral in rotation with said shaft.
  • This mechanism is in particular intended to be integrated into a timepiece.
  • the figure 1 and 2 illustrate a first embodiment of an animation mechanism 1 according to the invention.
  • the latter comprises a first decorative object 11 and a second decorative object 23, supported by a particular support system 13.
  • the first decorative object is three-dimensional in shape and can be a jewel, another decorative object (sculpture, glass ball, a piece of stone, ...), or an astral representation which represents, for example, a hemisphere or the entirety of the earth, any planet, the moon, the sun, a portion of the celestial vault, at least part of any other or similar star.
  • the second decorative object 23 is off center relative to the first 11, and is also of three-dimensional shape (sphere, hemisphere, etc.).
  • each of said decorative objects 11, 23 is distinct from the support system 13, and is not a functional element such as a screw or the like.
  • the support system 13 connects the decorative objects 11, 23 to a frame element (not shown) via a pair of pivots 13a carried by supports 13m arranged to be fixed on said frame (see the picture 2 ).
  • pivots 13a define a first axis of rotation A1, around which a first frame 13b is pivoted (illustrated exclusively on the picture 2 so as not to overload the figure 1 ) formed of an annular ring of generally circular shape in the illustrated construction. Other shapes (oval, square, rectangular, etc.) are also possible, and the first frame 13b need not be a complete ring.
  • This frame 13b carries a pair of intermediate pivots 13d, which define a second axis of rotation A2, which is substantially orthogonal with respect to said first axis A1.
  • An inner frame 13f is pivotally mounted around this second axis A2 inside the first frame 13b and carries the first decorative object 11.
  • the inner frame 13f takes the form of a circular board in the variant illustrated, but other shapes are possible (polygonal, skeleton, or another ad hoc shape).
  • the decorative object 11 is supported by a shaft 13h, which passes through the inner frame 13f and is mounted in bearings 13k provided in said inner frame 13f so that said shaft 13h can pivot relative to the latter.
  • the support system defines a gimbal support, which gives the inner frame 13f as well as the two decorative objects 11, 23 two degrees of freedom in rotation around the axes A1 and A2 , and substantially no translational degrees of freedom.
  • the pivoting of the shaft 13h relative to the inner frame 13f gives a third degree of freedom in rotation to the first decorative object 11 about a third axis A3, which corresponds to the geometric axis of the shaft 13h.
  • this third degree of freedom is not mandatory, in which case the first decorative object 11, and optionally also the shaft 13h, can be integral in rotation with the inner frame 13f.
  • the driving of the first decorative object 11 around the third axis A3 is ensured by the cooperation between the teeth of a pinion 13l integral with the shaft 13h and a conical toothing 17 which is coaxial with the drive wheel set 15 and is fixed in the construction shown.
  • a conical toothing 17 which is coaxial with the drive wheel set 15 and is fixed in the construction shown.
  • Other forms of toothing are also possible, such as for example an internal conical toothing carried by a crown or other ad hoc gears.
  • the teeth 17 can alternatively be driven in rotation instead of being fixed relative to the frame.
  • the pinion 13l as well as the toothing 17 are not present.
  • the mechanism further comprises a mobile drive 15, which comprises a toothed wheel 15a arranged to be driven by a driving source 5, such as a barrel housing a mainspring, an electric motor or the like, a transmission 9 of any shape that can be interposed kinematically between the driving source 5 and the drive wheel 15, if desired.
  • a driving source 5 such as a barrel housing a mainspring, an electric motor or the like
  • a transmission 9 of any shape that can be interposed kinematically between the driving source 5 and the drive wheel 15, if desired.
  • the driving source 5 can be dedicated to the animation mechanism, or can be part of a conventional watch movement.
  • the eccentric drive element 15b as illustrated takes the form of a lever or a bent crank fixed on the shaft 15d, the free end of the eccentric element 15b cooperating with the end of the shaft 13h in order to drive it along a substantially circular path, the end of shaft 13h being able to pivot in an ad hoc bearing provided at the free end of the element eccentric.
  • the inner frame 13f is driven in a compound movement having two degrees of freedom in rotation, the amplitude of which is defined by the geometry of the support system 13 as well as the radius of the eccentric drive element 15b. This movement is back and forth around each of the axes A1 and A2, which creates an inclined orbital movement of the first decorative object 11.
  • the decorative object 11 pivots around the three axes A1, A2, A3.
  • This fixed cover 25 is arranged to cover part of the first decorative object 11, for example in order to hide the part of the earth which is in the shade.
  • a rotation of the first decorative object 11 around the third axis A3 is not compulsory.
  • the fixed toothing 17 as well as the pinion 13l integral with the shaft 13h may not be present, the movement of the first decorative object 11 thus being defined exclusively by rotations back and forth around the two axes. A1 and A2.
  • the shaft 13h carries a toothed member 13n which is fixed to it in rotation.
  • This toothed member 13n meshes with an off-center mobile 21 carrying a pivoting cover 21a which partially surrounds said second decorative object 23 and is arranged to pivot around the axis of the mobile 21.
  • the second object decorative 23 is integral in rotation with the inner frame 13f, and therefore does not pivot around its own axis.
  • this construction can, for example, represent the phases of the moon as well as the approximate portion of the earth which is illuminated by the sun in real time, or according to an accelerated animation (which may correspond to accelerated reality or may be fanciful), and in any case the gimbal movement makes it possible to view the two decorative objects 11, 23 according to a greater number of angles compared to the prior art, with the exception parts covered by the respective covers 21a and 25 (if present).
  • the elements 13n and 21, and/or one, the other or all of the two covers 21a, 25, may not be present.
  • the picture 3 illustrates another embodiment of an animation mechanism 1 according to the invention.
  • This variant differs from that of figure 1 and 2 in that the second object 23 is mounted on the inner frame 13f orbitally.
  • the mechanism further comprises a rotating plate 27 which carries the second decorative object 23 and which is loosely mounted around the shaft 13h so that it can rotate around axis A3.
  • This plate 27 also carries the mobile 21, which is pivotally mounted on this first and comprises an upper wheel 21b meshing with the toothed member 13n as well as with a lower wheel 21c which meshes with an additional fixed wheel 29, integral with the frame. interior 13f.

  • the rotary board 27 comprises an extension 27a which surrounds a part of the additional wheel 21b and extends through the center of the mobile 21 in order to position the second object 23 on the visible side of the plate 27.
  • the second decorative object 23 orbits around the first decorative object 11, and the cover 21a moves relative to the second decorative object 23 as described above.
  • the figure 4 illustrates yet another variant of an animation mechanism 1 according to the invention, which differs from that of the picture 3 in that the second decorative object 23 is also arranged to pivot around its own axis A5.
  • the second decorative object 23 is fixed in rotation to a wheel 23a which meshes with a mobile satellite 23b pivotally mounted on the wheel 21c and which meshes with an additional toothing 21d fixed to the additional wheel 21b in order to form a differential gear.
  • the second decorative object 23 orbits around the axis A3 and pivots around its own axis A5, the speeds of rotation of the various components being freely selectable by modifying the gear ratios.
  • the covers 21a, 25 are optional in this variant, and that the axis A5 may or may not be parallel to the axis A3, which also applies to all the embodiments.
  • This arrangement is particularly suitable for animating the rotation of the earth (or of another planet) around the sun in real or accelerated time, but other animations are also possible.
  • the figure 5 illustrates a variant of an animation mechanism 1 according to the invention, which differs from those of figures 1 to 4 as will follow later.
  • the first decorative object 11 is carried by an additional frame 13p, mounted in the inner frame 13f pivoting around the axis A3. This frame 13p is thus decoupled from the toothed member 13n, and these two elements 13p, 13n can thus pivot relative to each other.
  • the first decorative object 11 is also integral with the additional frame 13p, the cover 21a being arranged in the same way as in the embodiment of the figure 1 and 2 and driven in rotation by the toothed member 13n, secured to the shaft 13h.
  • the additional frame 13p has a peripheral toothing which serves to drive it around the axis A3 via an intermediate transmission 31 of any shape (here composed of a plurality of transmissions pivoted on the inner frame 13f) which takes force on a pinion 13q secured to the shaft 13h.
  • the set of two decorative objects 11, 23 pivot around the axis A3, and the speed of rotation of the cover 21a can be chosen freely with respect to that of the additional frame 13p, by modifying the gear ratios of the intermediate transmission 31 or also the ratios between the toothed member 13n and the mobile 21.
  • the first decorative object 11 is integral in rotation with the shaft 13h instead of the additional frame 13p, which allows the two decorative objects 11, 23 to pivot around the axis A3 at rotational speeds different.
  • the figure 6 illustrates yet another variant of an animation mechanism 1 according to the invention, which differs from that of the figure 1 and 2 as following.
  • Mechanism 1 of the figure 6 also includes a raising and lowering system 33, arranged to raise and lower the second decorative object 23 relative to the plane of the inner frame 13f.
  • This raising and lowering system 33 is carried by the lower frame 13f, on its lower side (that is to say its side facing the mobile drive 15).
  • the second decorative object 23 is carried by a threaded rod 33a, which is indexed in rotation relative to the inner frame 13f by ad hoc means (not shown) such that the threaded rod 33a cannot pivot relative to said inner frame 13f.
  • the threaded rod 33a is engaged in a threaded tube 33b, and consequently a rotation of the threaded tube 33b in one direction or the other around the axis A5 will cause the threaded rod 33a and thus the second decorative object 23 to rise respectively.
  • This rotation is ensured by an intermediate transmission 31 driven by a toothed member 13q integral in rotation with the shaft 13h similarly to the variant of the figure 5 , and it is for this reason that similar elements with the latter have the same reference signs.
  • the intermediate transmission 31 of the present variant comprises an intermittent train consisting of two partial-toothed wheels 31a, 31b, which mesh with corresponding teeth 33c, 33d which are integral in rotation with the threaded tube 33b and arranged to pivot in two directions of rotation. opposite rotation.
  • Each partial-toothed wheel 31a has a toothing extending over half of its circumference, and the two toothings are arranged such that a 360° pivoting of each of the two wheels 31a, 31b in their opposite directions of rotation, will first cause a drive of the threaded tube 33b in a first direction of rotation under the control of one of the wheels 31a, 3b, then a drive of the threaded tube 33b in the other direction, under the control of the other wheel 31b, 31a, and this symmetrically.
  • the details of the other elements of the intermediate transmission 31 for reversing the direction of rotation of one of the wheels 31a, 31b relative to the other are within the reach of those skilled in the art and do not need to be described here. .
  • the second decorative object 23 will rise and fall during the operation of the mechanism 1, and can represent for example the displacement of the moon with respect to the equatorial plane of the earth due to the fact that the orbit of the moon does not is not coplanar with the earth's equator.
