Title:
JEWELRY THAT REVERSIBLY TRANSITIONS BETWEEN TWO DIFFERENT CONFIGURATIONS
Document Type and Number:
WIPO Patent Application WO/2019/070386
Kind Code:
A4
Abstract:
Article of jewelry that reversibly transitions between two different ornamentations by way of a plurality of solid strands, each strand formed from a two-way shape memory alloy trained to reversibly transition between two set positions in response to two different temperatures, where the strands are anchored from shape memory movement at a proximal end and connected to distal elements at a distal end, thereby directing shape memory movement of the distal elements in response to the two different temperatures.

AMENDED CLAIMS

received by the International Bureau on 23 May 2019 (23.05.2019)

What is claimed is:

1. An article of jewelry that reversibly transitions between two different ornamentations, the article of jewelry comprising a plurality of solid strands, each strand formed from a two-way shape memory alloy trained to reversibly transition between two set positions in response to two different temperatures, wherein one of the two set positions differs between two different strands, wherein the strands are anchored at a proximal end and connected to distal elements at a distal end, thereby directing shape memory movement of the distal elements in response to the two different temperatures.

2. The article of jewelry according to claim 1, wherein the shape memory alloy is a nickel titanium alloy, in particular nitinol.

3. The article of jewelry according to claim 1, wherein the plurality of strands is arranged in layers so that strands having a set position comprising a larger arc measure are positioned outside of strands comprising a set position comprising a smaller arc measure.

4. The article of jewelry according to claim 1, wherein the two set positions differ between the two different strands.

5. The article of jewelry according to claim 1, wherein at least some of the plurality of strands transition between arcs of different measure.

6. The article of jewelry according to claim 1, wherein at least some of the plurality of strands comprise a tighter coil in one set position compared to another set position.

7. The article of jewelry according to claim 1, wherein at least some of the plurality of strands transition between linear and non-linear set positions. REPLACEMENT SHEET

8. The article of jewelry according to claim 1, wherein, in response to the two different temperatures, a first set of distal elements closes against one another in a first set position and opens away from one another in a second set position.

9. The article of jewelry according to claim 8, wherein, in response to the two different temperatures, a first set of distal elements closes against one another in a first set position to hide an inner ornamentation and opens away from one another in a second set position to display the inner ornamentation.

10. The article of jewelry according to claim 1, wherein a first set of distal elements comprise leaflets that close against one another in a first set position and open away from another in a second set position.

11. The article of jewelry according to claim 9, wherein the leaflets close against one another to hide an inner ornamentation in a first set position and open away from one another to reveal the inner ornamentation in a second set position.

12. The article of jewelry according to claim 11, wherein a second set of distal elements comprise precious or semi-precious gems maintained outside of the leaflets.

13. The article of jewelry according to claim 1, wherein the distal elements are precious or semi-precious gems.

14. The article of jewelry according to claim 13, wherein the gems are independently selected from the group consisting of an agate, an alexandrite, an amber, an ametrine, an amethyst, an aquamarine, an apatile, a beryl, a bloodstone, a chrysoberyl or cat- eye, a citrine, a corundum, a chalcedony, a chysocolla, a coral, a diamond, an emerald, a green beryl, a garnet, a quartz, a lolite, a jadcite, a kupzite, a lapis lazuli, a moonstone, a malachite, a moamite, an onyx, an opal, a pearl, a peridot, a red corundum, a ruby, a sardonyx, a sapphire, a spessartime, a sphene, a spinel, a star ruby and sapphire, a sunstone, a tanzanite a tiger eye, a tourmaline, a topaz, a turquoise, a tsavorite, and a zircon.

15. An article of jewelry comprising precious or semi-precious gems that interchangeably connect to a fenestrated base, each gem held by a bezel, characterized in that the bezel comprises a shape memory alloy trained to reversibly transition between two set

16 REPLACEMENT SHEET positions in response to two different temperatures, wherein a first set position locks the bezel through the fenestrations of the base and a second set position releases the bezel from the fenestrations of the base.

16. An article of jewelry that reversibly transitions between two different ornamentations, the article of jewelry comprising a plurality of solid strands, each strand formed from a two-way shape memory alloy trained to reversibly transition between two set positions in response to two different temperatures, wherein the strands are anchored at a proximal end and connected to distal elements at a distal end, thereby directing shape memory movement of the distal elements in response to the two different temperatures, wherein a first set of distal elements comprises leaflets that close against one another in a first set position and open away from another in a second set position.
