Detailed Description of the Preferred Embodiment

The following description is not intended to limit the scope of the invention in any way as it is exemplary in nature, serving to describe the best mode of the invention known to the inventors as of the filing date hereof. Consequently, changes may be made in the arrangement and/or function of any of the elements described in the exemplary embodiments disclosed herein without departing from the spirit and scope of the invention.

The system 100, 200, 300, 500, 600, 800 according to this invention includes at least one decorative element 104, 224, 304, 344, 802 activated so as to move in at least one liquid 106, 206, 306, 506, 606, 830 by a displacement mechanism 1 10, 1 12, 1 14, 1 16, 316, 326, 510, 514, 516, 610, 614, 616, 804, 806, 820, 822. The liquid 106, 206, 306, 506, 606, 830 shares a substantially similar refraction index as the displacement mechanism or part of the displacement mechanism.

Referring now to FIG. 1, at least a part of the system 100 is immersed in a fluid 106, such fluid being a liquid having a refraction index substantially identical to the refraction index of selected parts 102, 1 10, 112, 1 14, 1 16 of the displacement mechanism that are intended to be rendered invisible or essentially invisible to an observer. The displacement mechanism may consist of a chain 1 16 of links 102 made of a material having a refraction index substantially identical to the refraction index of the surrounding liquid 106 so as to be essentially invisible to an observer. For a typical fluid such as glycerine or mineral oil, suitable materials for the parts 102, 1 10, 1 12, 1 14, 1 16 that are intended to be rendered invisible or essentially invisible to an observer are for example borosilicate, crystalline glass, fused silica, crown glass, flint glass, quartz, transparent ceramic (in particular Zerodur® or spinel), sapphire, polymethyl methacrylate (PMMA), polycarbonate, polyurethane. The chain 1 16 may include visible links 104 made of a material of refraction index significantly different from the refraction index of the surrounding liquid 106, such visible links may be made of precious metals or any other appropriate materials. Decorative elements 344, 802 may also be mounted on the invisible links 102 or on the visible links 104. The chain 1 16 of invisible links 102 and visible links 104 is mobilized via at least one gear wheel 1 14, and driven through a circuit defined by pulleys 1 10 and, optionally, guides 1 12. The pulleys 1 10, the guides 1 12 and/or the gear wheel 1 14 may be made of a material having a refraction index substantially identical to the refraction index of the surrounding liquid 106 so as to be at least substantially invisible to the user/wearer. The actuation mechanism (shown in schematic form as reference numeral 134) activates the at least one gear wheel 1 14 via a liquid- or watertight transmission (shown in schematic form as reference numeral 124). Such liquid- or watertight transmission 124 may be a magnetic transmission, a direct transmission with rubber seals, a substantially linear transmission encapsulated in a bellows, a hydraulic transmission or any appropriate transmission as known in the industry. The actuation mechanism 134 may be a direct action from the user, or a mechanism storing energy (mechanically, electrically, chemically, hydraulically, etc) and delivering movement at random so as to create a surprising effect, or upon triggering by the user, or a time-keeping mechanism providing a regular animation, optionally activated at specific points in time, like the top of the hour. In such case, an indication of time- related information may be provided. In case the system is implemented in a wearable item, the source of energy for the animation may be provided by a combination of a movement of the wearer and the effect of gravity on a pendulum or an oscillating mass rewinding the actuation mechanism 134.

Referring now to FIG. 2, the path 222 defined for the chain 116, 316, 516, 616, 806 by pulleys 110, 510, 610 and guides 112 may have a well-known shape 222 such as that of an automobile race circuit (e.g. the Bugatti circuit in Le Mans), and the chain may carry one or more decorative element 224 (e.g. a miniature race car), and drive it along indicia 226 so as to represent the passing of time. The pulleys 110, 510, 610, guides 112, chain links 102, 502, 602, and gear wheel 114, 514, 614 may be made of a material having a refraction index substantially identical to the refraction index of the surrounding liquid 206 so as to be invisible to the user/wearer

Refering now to FIGs. 3A to 3C and FIG. 4, the system 300 allows the representation 350 of a word“LOVE”, using a chain 316 of invisible links 302 and visible links 304, in combination with fixed decoration elements 342 on the display 340. In this example, the visible links 304 form a continuous chain 316, and differences of height allow crossing of the chain 316 in order to form closed shapes 352. On one or more of the links 302, 304, a decorative element 344 such as a stone may be mounted. The return path of the chain 316 may be placed under a cover 346 so as to be outside of the field of view of the user/wearer, so that when the animation movement continues, the word“LOVE” disappears progressively. In the same way, displaying words like“NIGHT” and “DAY” at the appropriate moments, or any other words or shapes may provide an interesting animation combined with an indication of time.

Referring now to FIG. 5, the chain links 502 are attached to each other with kneecap joints

532, and contain appropriate rack shapes 534 so as to be mobilized via a gear wheel 514 and guided by pulleys 510 or other shaped guides. Each chain link 502 may carry one or more decorative elements 344, 802. The geometry of the chain links 502 may be appropriately designed so as to limit the bowing or buckling of the chain 516 when being pushed by the one or more gear wheel 514, allowing the bidirectional mobilization of the animation. The kneecap joints 532, the rack shapes 534 and the gear wheel 514 may be treated for gliding properties such as with a “TEFLON”® coating. The pulleys 510, guides, chain links 502 and gear wheel 514 may be made of a material having a refraction index substantially identical to the refraction index of the surrounding liquid 506 so as to be invisible to the user/wearer.

Referring now to FIG. 6, the chain 616 is cut out ofbulk material such as glass, the chain links may consist of more rigid areas 602 separated by thinner and more flexible areas 632, so that the chain 616 has a sufficient flexibility to follow an animation path 222. Visible decoration elements 344, 802 may be mounted on any of the rigid areas 602. Mobilization of the chain 616 may be made with a rack 634 formed or cut in the chain 616, while the chain passes between one or more pulleys 610 and at least one gearwheel 614.

In the above, the description of a chain 116, 316, 516, 616 is given as example. Other embodiments of the same function may be made with fibers, in particular polymer or glass fibers, in particular optical fibers may be found with a refraction index corresponding to substantially transparent liquids. Chain links connected to one another with magnets may also be used.

Referring now to FIGs.7 A and 7B, the mobile decorative elements 802 are guided by channels 804 and moved by a displacement transmitting element 806 which transmits a movement generated by the user via a pulley 820, a slider 822, or any other appropriate mechanism (not represented here). Instead of being generated by the user, the movement may also be generated by a clock system (not represented here), such clock system being electronically or mechanically powered. The guiding of the decorative elements 802 in the channels 804 may allow some degree of freedom in several directions to give the decorative elements a more lively behavior when the system 800 is moved relative to gravity, or when the system 800 is accelerated in any direction by its wearer. Parts 804, 806, 820 of the displacement mechanism that are in the visible area of the accessory 810 may be made in a material with a refraction index close to the refraction index of the surrounding fluid 830 to be substantially invisible. For example, the displacement transmitting elements 806 may be advantageously made of glass fibers but any chain such as described above may also be used. The surrounding fluid 830 may be at least one liquid. The surrounding fluid may be transparent or colored. Components, elements, or portions of the displacement mechanism (not represented here) that are in non-visible areas of the system 800 may be made in any material appropriate for their function.

Some mobile decorative elements 344, 802 may be hidden in non-visible areas 346 of the system 100, 200, 300, 500, 600, 800, and appear when the animation is triggered.

Some mobile elements 344, 802 may hide each other in certain positions within the system 100, 200, 300, 500, 600, 800, and the hidden mobile element 344, 802 would then suddenly appear as an image when the animation is triggered.

Some decoration elements 344, 802 may change color when they are on top of each other, for example a semi-transparent yellow part on top of a semi-transparent blue part would appear green.

In an advantage, the system 100, 300, 500, 600, 800 animates decorative objects, personal accessories, jewelry , timepieces and/or watches.

In another advantage, the invention 200, 300, 800 provides an indication on decorative objects, such as time-related indications.

In still another advantage, the invention 100, 200, 300, 500, 600, 800 provides an invisible displacement mechanism 110, 112, 114, 116, 316, 326, 510, 514, 516, 610, 614, 616, 804, 806, 820, 822 in decorative objects and thus provides a magical effect.

In a further advantage, the system 100, 200, 300, 500, 600, 800 creates an apparently living decoration for personal accessories.

In another advantage, the invention changes its appearance when moved.
