Description

Technical Field

[0001] This invention relates to the field of horology. More particularly, this invention relates to an animation mechanism comprising at least two ornaments, which are especially capable of being represented as celestial bodies. Background Technology

[0002] Document FR2988866 describes an animation mechanism for gemstones or semi-precious stones, in which an active drivespring is configured to animate the gemstone as it rotates about a single axis of rotation via a flexible belt. The gemstone is mounted on a shaft by four claws or clamps that hold the stone in place. However, the movement of the gemstone is monotonous and only allows one facet to be seen, which is always presented at the same angle as the wearer, thus limiting its visibility.

[0003] Document CH708473 discloses a celestial animation mechanism comprising a pivot disk representing the Earth and a larger-diameter disk with an eccentric circular aperture defining a representation of the Moon. When the mechanism is in operation, the Earth representation rotates, while the Moon representation orbits the Earth. A supplementary disk, serving as the base for the Moon disk, also enables the display of the Moon's phase. This mechanism is indeed interesting, but it is limited to flat display.

[0004] The commercially available GMT tool from Greubel Forsey presents a three-dimensional representation of the Earth's Northern Hemisphere, rotating in 24-hour increments. The visibility of this convex representation is relatively limited, especially when trying to see areas near the equator where there is no representation of the moon.

[0005] Document CH707163 describes various variations of the mechanism, including a three-dimensional representation of the Moon orbiting an axis on which the Earth can be represented. However, the visibility of the Moon's representation is limited, and the possibilities for other variations are also relatively limited.

[0006] Document WO2006 / 050743 describes a winding mechanism for an automatic watch. Even considering that a timepiece can be an "ornament," this document does not disclose a second ornament within the scope of this invention.

[0007] Document WO2013 / 004782 discloses a "cardan" tourbillon mechanism in which the sprung balance is carried by an inner ring mounted to pivot inside the outer ring. Again, and even considering that the sprung balance can be a "decorative" element, no second decorative element within the meaning of this invention is disclosed therein.

[0008] Therefore, the objective of this invention is to propose an animation mechanism that at least partially overcomes the aforementioned defects. Summary of the Invention

[0009] More specifically, the present invention relates to an animation mechanism. Such a mechanism includes a support system for carrying a first ornament, the support system being designed to be animated, directly or indirectly, upon rotation about a first axis of rotation and about a second axis of rotation, under the action of a drive source. The drive source may be mechanical or electric, and may be specifically designed for this mechanism, or may be a drive source that supplies driving force to a clock.

[0010] The support system includes a first frame mounted to pivot on a cage member about a first axis of rotation, and an inner frame mounted to pivot within the first frame about a second axis of rotation, the second axis of rotation being substantially orthogonal to the first axis of rotation (i.e., the inner frame pivots on the first frame, thereby defining a universal joint system), the inner frame directly or indirectly carrying a second decorative element. The inner frame (and thus the first decorative element) is configured to be driven by an eccentric drive member rotatably fixed to a drive wheel, which is configured to be directly or indirectly driven by the drive source.

[0011] Through these methods, the original animation was obtained, and the resulting reciprocating movement around the two axes allowed for good visualization of the two ornaments. This animation can represent a wide range of possibilities, especially when the ornaments are represented as celestial bodies, as will become clear from the detailed description.

[0012] Advantageously, the first ornament is supported by a bearing, the shaft of which is mounted to pivot about a third axis of rotation within the inner frame. This shaft is rotatably fixed to a pinion that meshes with teeth coaxial with the drive wheel, and this pinion can be fixed or animated with rotation. Thus, the first ornament can pivot about its own axis of rotation.

[0013] In another variation, the first ornament is supported by an auxiliary frame pivotally mounted about a third axis of rotation defined by the aforementioned shaft. The auxiliary frame is configured to be rotated and driven by an intermediate transmission supported by an inner frame and configured to be driven by a toothed organ rotatably fixed to the shaft.

[0014] Therefore, if necessary, the first ornament can be configured to pivot at a speed different from that of the shaft.

[0015] Advantageously, the eccentric drive component is a crank or rod, which represents a relatively simple and easy-to-implement solution.

[0016] Advantageously, the second ornament is configured to move along a track about the first ornament. In this case, the second ornament can be supported by a rotating plate configured to pivot about the third axis of rotation.

[0017] Advantageously, the rotating plate is driven by a wheel pivotally mounted on it, engaging on one hand a toothed mechanism and on the other hand an auxiliary fixed wheel rotatably fixed to the inner frame, wherein the toothed mechanism is rotatably fixed to the shaft. When the shaft pivots, the plate is thus driven to rotate, and the second decoration travels around the track of the first decoration.

[0018] Advantageously, setting the second ornament to rotate about its own axis allows the designer (constructor) a great deal of possibilities regarding animation.

[0019] Advantageously, the second ornament is configured to rise and fall relative to the plane of the inner frame. This makes it possible, in particular, to represent the fact that the moon's orbit is not coplanar with the earth's equator, or simply to animate another object in this way.

[0020] Advantageously, the apparatus also includes a cover surrounding a portion of the first ornament, which has an illuminated portion for example, representing the Earth, when the first ornament is a representation of the sun and the second ornament is a representation of the Earth.

[0021] Advantageously, the pivot guard is configured to pivot about the second ornament, which serves to illustrate the lunar phase when the first ornament represents the Earth and the second ornament represents the Moon. In such a case, the pivot cover can be rotatably fixed to a wheel, which is configured to be driven by a toothed mechanism rotatably fixed to the shaft.

[0022] This mechanism is specifically designed to be incorporated into clocks and watches. Attached Figure Description

[0030] Figure 1 and Figure 2 A first embodiment of the animation mechanism 1 according to the present invention is illustrated.

[0031] The animation structure includes a first ornament 11 and a second ornament 23 supported by a specific support system 13. The first ornament has a three-dimensional form and can be a jewel, another ornament (sculpture, glass ball, a stone, etc.), or a representation of a celestial body, such as representing a hemisphere or all of the Earth, any planet, the Moon, the Sun, a portion of the night sky, or at least a portion of any other astral body. The second ornament 23 is off-center relative to the first ornament 11 and is also a three-dimensional form (sphere, hemisphere, etc.). For example, it can be another jewel or any other object, another representation of a celestial body, such as a representation of the Moon when the first ornament 11 represents the Earth, a representation of a planet when the first ornament 11 represents the Sun, a representation of the Earth when the first object represents the Sun or the night sky, or even a representation of any other object representing a satellite of the celestial body represented by the first ornament 11. It should be noted that each of the decorative elements 11 and 23 is different from the support system 13 and is not a functional component such as a screw, balance, escapement, spring, wheel, or support. In other words, the decorative elements 11 and 23 are purely decorative and have no mechanical function in motion, whether it is a movement function or a support function.

[0032] The support system 13 connects the ornaments 11, 23 to the cage-like component (not shown) via a pair of pivots 13a, which are supported by a support member 13m configured to be fixed to the cage-like component (see [link to support system]). Figure 2 ).

[0033] These pivots 13a define a first axis of rotation A1, and the first frame 13b (specifically in...) Figure 2 Examples are provided to prevent... Figure 1 The first frame 13b, in the illustrated configuration, is formed of a generally circular loop (overburdened) and pivots about the first axis of rotation A1. Other forms (elliptical, square, rectangular, etc.) are also possible, and a complete loop is not mandatory for the first frame 13b. The first frame 13b carries a pair of intermediate pivots 13d, which define a second axis of rotation A2 that is substantially orthogonal to the first axis A1. An inner frame 13f is mounted inside the first frame 13b to pivot about the second axis A2 and to carry the first ornament 11. In the illustrated variant, the inner frame 13f takes the form of a circular plate, but other forms are possible (polygonal, skeleton, or any other special form).

[0034] In the illustrated configuration, the ornament 11 is supported by a shaft 13h that passes through an inner frame 13f and is mounted in a bearing 13k disposed in the inner frame 13f, such that the shaft 13h can pivot relative to the inner frame.

[0035] As is clear from the above, the support system defines a cardan joint support that imparts two rotational degrees of freedom about axes A1 and A2 to the inner frame 13f and the two decorative elements 11 and 23, and substantially no translational degrees of freedom. The pivoting of axis 13h relative to the inner frame 13f imparts a third rotational degree of freedom to the first decorative element 11 about a third axis A3 corresponding to the geometric axis of axis 13h. However, this third degree of freedom is not mandatory; in this case, the first decorative element 11, and optionally, axis 13h, can be rotatably fixed to the inner frame 13f.

[0036] The drive of the first ornament 11 about the third axis A3 is ensured by the engagement between the teeth of the pinion 13l fixed to the shaft 13h and the conical toothing 17, which is coaxial with the drive wheel 15 and fixed in the illustrated configuration. Other types of teeth are also possible, for example, internal conical teeth carried by a crown ring or other specially designed gear mechanism. Furthermore, the tooth 17 can optionally be rotated instead of being fixed relative to the chassis. When the first ornament 11 is rotated and fixed to the inner frame 13f, the pinion 13l and the tooth 17 are not present.

[0037] To animate the inner frame 13f and thus the ornaments 11 and 23, the mechanism further includes: a drive wheel 15 comprising a toothed wheel 15a configured to be driven by a drive source 5 (such as a cylinder housing a drive spring, motor, etc.); and, if desired, any form of transmission 9 that can be kinematically inserted between the drive source 5 and the drive wheel 15. Obviously, auxiliary gears and / or other forms of motion linkages (such as belts or chains) can also be inserted. The drive source 5 can be dedicated to the animation mechanism or can form part of a conventional clock movement.

[0038] The drive wheel 15 (whose axis of rotation A4 is positioned substantially to intersect the intersection of axes A1 and A2) also includes an eccentric drive component 15b, which is rotatably fixed to the gear 15a and connected to the gear via a shaft 15d. The eccentric drive component 15b, as illustrated, takes the form of a rod or crank fixed to the shaft 15d, the free end of which engages with the end of the shaft 13h to drive the shaft along a substantially circular path, the end of which is pivotable at a specially designed bearing located at the free end of the eccentric component. Thus, as the drive wheel 15 rotates, the inner frame 13f is driven by a compound movement having two rotational degrees of freedom, the magnitude of which is defined by the geometry of the support system 13 and the radius of the eccentric drive component 15b. This movement is reciprocating about each of the axes A1 and A2, resulting in a tilted track movement of the first ornament 11.

[0039] Meanwhile, the teeth of the pinion 13l, which is fixed to the shaft 13h, roll on the fixed teeth 17, which causes the ornament 11 to pivot about the third axis A3.

[0040] Through these means, the ornament 11 pivots around three axes A1, A2, and A3.

[0041] Clearly, other configurations of the eccentric drive component 15b are also possible, and these gear ratios can be adapted to the designer's needs to animate the ornament 11 at the desired rotational speeds around the three axes of rotation.

[0042] It should also be noted that the presence of the fixing cover 25 is optional and it is fixed to the inner frame 13f. The fixing cover 25 is configured to cover part of the first ornament 11, for example, to hide the shaded portion of the earth.

[0043] As mentioned above, the rotation of the first ornament 11 about the third axis A3 is not mandatory. In this case, there is no need for the fixed teeth 17 and pinion 13l fixed to the axis 13h, and thus the movement of the first ornament 11 is specifically limited by reciprocating rotation about the two axes A1 and A2.

[0044] Turning now to the second ornament 23, shaft 13h carries a toothed component 13n, which is rotatably fixed to the shaft. The toothed component 13n engages with an eccentric wheel 21, which carries a pivot cover 21a, which partially surrounds the second ornament 23 and is configured to pivot about the axis of the wheel 21. In this variant, the second ornament 23 is rotatably fixed to the inner frame 13f and therefore does not pivot about its own axis.

[0045] Depending on the selected gear ratio and drive speed, this configuration can, for example, represent the phases of the moon and the approximate portion of the earth illuminated by the sun in real time or according to an accelerated animation (which may correspond to accelerated reality or may be fantasy), and in any case, the movement of the gimbal allows the two ornaments 11, 23 (except for the portions covered by the corresponding covers 21a and 25 (if present)) to be viewed from a greater angle than in the prior art.

[0046] However, in the simplified variant, parts 13n and 21, and / or one or both of the two covers 21a, 25 are not required.

[0047] Figure 3 Another embodiment of the animation mechanism 1 according to the invention is illustrated. This variant is similar to... Figure 1 and Figure 2 The difference in this variant is that the second object 23 is mounted orbitally on the inner frame 13f. To achieve track movement of the second object 23 and its cover 21a, the mechanism also includes a rotating plate 27 that carries the second ornament 23 and is freely mounted on the shaft 13h, allowing the plate to pivot about axis A3. The plate 27 also carries a wheel 21 mounted to pivot on the plate, and the wheel comprises an upper wheel 21b and a lower wheel 21c. The upper wheel engages with a toothed component 13n and the lower wheel 21c, which engages with an auxiliary fixed wheel 29 fixed to the inner frame 13f. The two toothed components 21b and 21c constituting the wheel 21 are thus positioned on either side of the plate 27.

[0048] To support the second ornament 23, the rotating plate 27 includes an extension 27a that surrounds a portion of the auxiliary wheel 21b and extends through the center of the wheel 21 to position the second ornament 23 on the visible side of the plate 27.

[0049] When shaft 13h and toothed component 13n pivot, wheel 21 is driven to rotate, and its lower wheel 21c rolls on auxiliary fixed wheel 29. Therefore, plate 27 pivots about axis A3.

[0050] Through these means, the second ornament 23 moves around the first ornament 11 in a track, and the cover 21a moves relative to the second ornament 23 as described above.

[0051] This arrangement can also achieve the same results as above. Figure 1 and Figure 2 The animation described in the context of the implementation is the same as the animation.

[0052] Figure 4 Another variation of the animation mechanism 1 according to the invention is illustrated, which is similar to... Figure 3 The difference in the variant is that the second ornament 23 is also configured to pivot about its own axis A5. To do this, the second ornament 23 is rotatably fixed to wheel 23a, which meshes with a satellite wheel 23b mounted to pivot on wheel 21c, and with an auxiliary tooth 21d fixed to auxiliary wheel 21b to form a differential gear.

[0053] Through these means, the second ornament 23 orbits around axis A3 and pivots around its own axis A5, and the rotational speeds of the various components can be freely selected by modifying the transmission ratio. Furthermore, it is clear that covers 2a and 25 are optional in this variant, and axis A5 may or may not be parallel to axis A3, which also applies to all these embodiments.

[0054] This setup is particularly suitable for animate the Earth's (or another planet's) rotation around the Sun in real time or at an accelerated pace, but other animations are also possible.

[0055] Figure 5 A variant of the animation mechanism 1 according to the invention is illustrated, which is related to... Figures 1 to 4 The variations are as shown below.

[0056] The first ornament 11 is not carried by the shaft 13h, but by an auxiliary frame 13p mounted in the inner frame 13f and pivoting about axis A3. This frame 13p is therefore separate from the toothed component 13n, and the two components 13p and 13n can thus pivot relative to each other. The first ornament 11 is also fixed to the auxiliary frame 13p, and the cover 21a is positioned in relation to... Figure 1 and Figure 2 It is set up in the same manner as in the other embodiment, and is driven by the rotation of the toothed component 13n which is fixed to the shaft 13h.

[0057] The auxiliary frame 13p includes an outer peripheral tooth for driving the auxiliary frame about axis A3 via an intermediate transmission 31 of any kind (here consisting of a plurality of intermediate wheels pivoting on the inner frame 13f), which is powered by a pinion 13q fixed to shaft 13h.

[0058] In doing so, the two ornaments 11 and 23 pivot about axis A3, and by modifying the transmission ratio of the intermediate transmission device 31 or the transmission ratio between the toothed component 13n and the wheel 21, the rotational speed of the cover 21a can be freely selected relative to the rotational speed of the auxiliary frame 13p.

[0059] In a variant not illustrated, the first ornament 11 is rotated and fixed to the axis 13h instead of the auxiliary frame 13p, which allows the two ornaments 11, 23 to pivot about the axis A3 at different rotational speeds.

[0060] These arrangements, in particular, make it possible to represent the phases of the moon.

[0061] Figure 6 Another variation of the animation mechanism 1 according to the invention is illustrated, which is similar to... Figure 1 and Figure 2 The differences between the variants are as follows.

[0062] Figure 6 The mechanism 1 also includes a raising and lowering system 33, which is configured to raise and lower the second ornament 23 relative to the plane of the inner frame 13f.

[0063] The lifting system 33 is supported by the inner frame 13f on the bottom side of the inner frame (i.e., the side of the inner frame facing the drive wheel 15).

[0064] The second ornament 23 is supported by a screw 33a, which is indexed relative to the inner frame 13f by a special device (not shown), so that the screw 33a cannot pivot relative to the inner frame 13f.

[0065] The screw 33a is engaged in a tapped tube 33b, so that rotation of the tapped tube 33b about axis A5 in one direction or another will correspondingly raise or lower the screw 33a and thus lower the second ornament 23. This rotation is ensured by an intermediate transmission device 31, which is composed of... Figure 5 The variant is similarly guided (conducted) by rotating and fixing the toothed component 13q to the shaft 13h, which is the same as... Figure 5 The reason why similar parts have the same designation.

[0066] The intermediate transmission device 31 of this variant includes an intermittent geartrain consisting of two wheels 31a and 31b with partial teeth. These partial teeth mesh with corresponding teeth 33c and 33d, which are rotatably fixed to the internally threaded tube 33b and configured to pivot in two opposite directions of rotation. Each wheel 31a has teeth extending over half its circumference, and these teeth are arranged such that a 360° pivot of each of the wheels 31a and 31b in their opposite directions of rotation will first drive the internally threaded tube 33b in a first direction of rotation under the control of one of the wheels 31a and 31b, and then drive the internally threaded tube 33b in the other direction under the control of the other wheel 31b and 31a, and this process is symmetrical. Details of the other components of the intermediate transmission device 31 used to reverse the rotation direction of one of the wheels 31a and 31b relative to the other wheel are readily available to those skilled in the art and need not be described herein.

[0067] Therefore, when mechanism 1 is in operation, the second ornament 23 will rise and fall, and since the moon's orbit is not coplanar with the earth's equator, the second ornament can, for example, represent the moon's movement relative to the earth's equatorial plane.

[0068] Of course, without departing from the framework of the present invention, other mechanisms for raising and lowering the second ornament 23 can be conceived, for example, in a manner similar to an automatic machine, based on a cam set to raise and lower the second ornament.

[0069] Although the invention has been described previously with reference to specific embodiments, other additional variations are contemplated without departing from the scope of the invention as defined by the claims.
