Description

[0001] The present invention relates to the field of jewelry, in particular to bracelets, rings and pendants.

[0002] The Applicant has observed a deep evolution in the field of high jewellery in terms of materials and shapes. Nevertheless, one constant is that high jewellery pieces are non-functional, that is, they do not have any technical function for the wearer of said jewellery piece. The jewellery piece may be equipped with mechanisms such as clasps, which are used to hold the jewellery piece in place or to secure it. These functions are secondary and decorative.

[0003] US111083256 provides a ring whose inner surface is recessed in cross section to form an annular channel. An NFC transponder is installed in the annular channel, and the transponder includes an antenna in the form of a coil etched on a cylindrical flexible substrate. The NFC transponder and the flexible substrate are encapsulated by a resin seal. However, the ring model has a variety of sizes to accommodate different finger diameters. Each size corresponds to a specific resin seal, NFC transponder and flexible substrate. This greatly increases the complexity of manufacturing. In addition, the signal transmitted by the antenna arranged in the annular channel inside the ring is poor. The size of the NFC transponder and the substrate imposes restrictions on the material selection of the ring, the shape of the ring and its size. The antenna of the NFC transponder rotates around the ring. However, the choice of material, shape and size is very important for jewelry and is related to artistic creation. Therefore, imposing such restrictions is a major disadvantage.

[0004] The applicant has designed and developed a piece of jewellery having a payment device that is independent of the size of the jewellery and that complies with the freedom of design of the jewellery ornament while providing high quality transmission.

[0005] The present invention provides a jewelry, in particular a ring, a bracelet or a pendant, comprising: a main body, the main body having an inner surface, an outer surface and an opening passing through the main body from the inner surface to the outer surface, the main body being made of a material selected from gold, silver, platinum, titanium, palladium, steel or gold-plated silver; an outer shell constituting a part of the outer surface of the jewelry and connected to the main body, the outer shell being made of a material selected from precious gemstones, fine gemstones, decorative gemstones, and leather; an inner shell constituting a part of the inner surface and connected to the main body, a closed shell being formed between the outer shell and the inner shell, the closed shell being substantially aligned with the opening or within the opening, the shell being semicircular, the inner shell being made of a material selected from precious gemstones, fine gemstones, decorative gemstones, and leather; a flexible tag arranged in the shell, the flexible tag comprising an electronic chip and an antenna arranged around the electronic chip, and screws fixing the outer shell and the inner shell together. The main body can be made of a variety of materials, in particular precious metals. The size of the tag is maintained from one size of the jewelry model to another size, and is suitable for a variety of jewelry models. The tag is hidden in the jewelry, so it does not have a visual and aesthetic impact.

[0053] In the field of jewelry, respecting the artistic freedom of the creator of the object is fundamental. Traditionally, artistic freedom was limited by the mechanical constraints of the materials used. The bold exploration of shapes led to the development of more durable materials. At the same time, there was a desire to work with original materials that were usually fragile.

[0054] Then, the miniaturization of communication electronics made it possible to consider incorporating them into jewelry. Nevertheless, the data throughput and transmission quality requirements are high, especially since high-quality jewelry cannot compete with low-end transmissions. Taking into account the analysis made, the applicant developed a jewelry suitable for high-performance radio communication electronics. The applicant pointed out several difficulties. Most of the volume of jewelry is made of metal, which is generally a poor transmitter of radio waves and even forms a considerable shield that attenuates the waves.

[0055] Additionally, jewelry pieces sometimes include other non-metallic materials. Despite the use of precious metals, Applicants have attempted to utilize such non-metallic materials to facilitate the transmission of radio waves.

[0056] Thus, the jewellery 1 has a general shape of an annulus. The jewellery 1 may be a ring. The jewellery 1 comprises a ring body 2. The structure of the ring body 2 means that it gives the jewellery 1 its general shape. The ring body 2 has a hole 3 or an inner surface, an outer surface 4 and an opening 5 passing through the ring body 2 from the hole 3 to the outer surface 4. The edge 6 of the ring body 2 has a free annular shape. In this embodiment, the edge 6 of the ring body 2 is arc-shaped. In other words, the ring body 2 has a common branch and two branches 8, 9 which are axially spaced apart according to the axis of the ring, and two remote branches connecting the common branch at each of their ends, see Figure 3 .

[0057] In the embodiment shown, the ring body 2 is annular and integrally made. The ring body 2 is symmetrical with respect to a plane perpendicular to the axis of the hole 3. The ring body 2 has a first solid part (at the bottom of the figure) and a second part (at the top of the figure). The thickness of the first part is variable in the radial direction, and the thickness is the smallest at a certain distance from the second part. The second part includes two axially spaced branches 8, 9, which define the opening 5. Each branch 8, 9 is arc-shaped. In the cross section, the branches 8, 9 have arc-shaped parts towards the edge 6 and towards the hole 3. Relative to the hole 3, the cross section of the branches 8, 9 is straight here, in particular, parallel to the axis of the hole 3. Towards the opening 5, the cross section of the branches 8, 9 is straight, for example radially oriented. At least one notch can be provided to facilitate positioning and holding other elements (mentioned below). The notch is formed continuously or discontinuously on the edge of the opening relative to the hole 3 and the edge 6, for example on the branches 8, 9.

[0058] The thickness of the branches 8, 9 is less than the thickness of the first portion at least in the vicinity of the first portion. Thus, a substantially radial surface 7 is formed between the first portion and the second portion on each side of the ring body 2. A recess 17 may be formed in the substantially radial surface 7. The recess 17 conforms to the shape of the ring body 2. The recess 17 is a blind portion.

[0059] The ring body 2 may be made of a material that forms a barrier to radio wave transmission. The ring body 2 is made of a material selected from the following: gold, silver, platinum, palladium, gold-plated silver, titanium, and steel.

[0060] The jewelry 1 comprises an outer shell 10 constituting a part of the outer surface 4 of the jewelry 1 and connected to the ring body 2. The jewelry 1 comprises an inner shell 11 constituting a part of the surface of the hole 3 and connected to the ring body 2. A housing 12 which is closed in the mounted state is formed between the outer shell 10 and the inner shell 11 and is generally aligned with or located in the opening 5. The housing 12 is semicircular. The jewelry 1 comprises a flexible tag 13 arranged in the housing 12. The tag 13 comprises an electronic chip 14 and an antenna 15 arranged around the electronic chip 14.

[0061] The jewelry 1 comprises a screw 20 that fixes the outer shell 10 and the inner shell 11 together. In the illustrated embodiment, a nut 21 is provided, which forms a bolt with the screw 20. The screw 20 has a head with a small thickness. The screw 20 is installed from the inside of the ring body 2. The nut 21 is installed from the outside. The screw 20 engages with the nut 21. The screw and the nut can be made of the same material as the ring body 2, or selected from the same group of materials. The nut can also include precious, exquisite or decorative gemstones.

[0062] The housing 10 is made in one piece. The housing 10 covers the opening 5 on the outside, in other words, opposite the hole 3. The housing 10 may also partially cover the branches 8, 9. The housing 10 is arc-shaped. The thickness of the housing 10 is between 1.0 mm and 3.0 mm.

[0063] The circumferential free end 30 of the housing 10 is connected to the substantially radial surface 7. The circumferential free end 30 of the housing 10 may be provided with a protrusion to extend into the recess 17. The housing 10 has a free outer surface 31 for artistic design or to support another component. The housing 10 has an inner surface 32 that delimits the shell 12. The inner surface may be recessed relative to the cylinder forming the geometric envelope of the housing 10 to increase the volume of the shell 12. Two ribs 33 may be formed at the boundaries of the recess. The ribs may be connected to the notches of the branches 8, 9.

[0064] A through hole 34 is formed in the housing 10, see [ Figure 6 ]. Alternatively, the hole is a blind threaded opening provided on the inner surface 32 for engagement with the screw 10. The hole 34 is radial. The hole 34 is arranged in the center of the housing 10. On the outside, the hole 34 may have a countersunk hole 44.

[0065] The housing 10 is made of a material selected from the group consisting of precious gemstones, fine gemstones, decorative gemstones, and leather.

[0066] The inner shell 11 is here made of two parts, each of which is made in one piece. In the embodiment shown, the two parts are symmetrical with respect to a plane passing through the axis. Alternatively, the inner shell 11 is a one-piece piece. The inner shell 11 covers the opening 5 on the inside, in other words, covers one side of the hole 3. The inner shell 11 is embedded between the branches 8, 9. The thickness of the inner shell 11 is between 1.0 mm and 2.0 mm.

[0067] The inner shell 11 is arc-shaped. The circumferential free end 30 of the inner shell 11 is connected to the edge of the opening 5. The inner shell 11 has an outer surface 35 that defines the shell 12. The outer surface 35 can be substantially smooth. The cross section of the outer surface 35 along the plane passing through the axis can be a straight line. The outer surface 35 is at least partially away from the inner surface 32. The inner shell 11 has an inner surface 36 that is flush with the hole 3 of the ring body 2. The inner shell 11 has an edge that is connected to the inner edge of the opening 5. Along the longitudinal axis direction, the inner shell 11 is longer than the aperture of the opening 5 and occupies a larger angular sector. Therefore, the inner shell 11 is located on the edge of the opening 5 in the installed state, especially on most of the edge, preferably on the entire edge, unless it is located at certain points where appropriate. The inner shell 11 is mounted on the ring body 2 from the outside (especially according to radial translation).

[0068] Once mounted on the ring body 2, the outer surface 35 is flush with the recess 17, see [ Figure 4 The inner surface 32 is flush with the hole 3, see [ Figure 7] The branches 8, 9 protrude axially from the inner shell 11, see Figure 4 and Figure 5 .

[0069] The inner shell 11 is made of a material selected from the following: precious gemstones, fine gemstones, decorative gemstones, leather.

[0070] In the embodiment shown, the ring body 2 includes a gasket 40. The gasket 40 is longitudinally oriented. The gasket 40 is parallel to the axis. The gasket 40 connects the branch 8 and the branch 9. The gasket 40 is installed approximately in the middle of the opening 5. The gasket 40 is arranged on the top of the ring body 2. The gasket 40 is flush with the hole 3, see [ Figure 2 The gasket 40 has a rectangular cross section and has a protrusion 41 in the middle of the gasket 40. The protrusion 41 is provided with a hole 42. The screw 20 is inserted into the hole 42. Figure 2 ], a member for fastening the jewelry 1. The projection 41 extends transversely relative to the gasket 40, that is, extends in the circumferential direction relative to the ring body 2. The projection 41 is flush with the hole 3, see [ Figure 2 The projection 41 projects slightly radially relative to the branches 8 and 9, see [ Figure 2 ] and is slightly radially recessed relative to the outer surface 35 of the inner shell 11.

[0071] In another embodiment, the ring body 2 does not have any gaskets. The inner shell is a one-piece product. The outer shell and the inner shell are then clamped by screws, and the inner shell is installed from the inside. The screws can also be engaged in the ring body, for example in one of the branches 8, 9 or in both branches 8, 9.

[0072] When flat, the tag 13 has a rectangular shape with rounded corners. The electronic chip 14 forms a protrusion relative to the rest of the tag 13. The inner surface 32 of the housing 10 has a corresponding groove at a distance from the free end 30 and the rib 33. The electronic chip 14 is offset relative to the entire tag 13. In the center of the tag 13, a through hole is formed for the screw 20. The antenna 15 is flatly wrapped around the electronic chip 14 and the hole. The body of the tag is made of a material that is flexible enough to adapt to the curvature of the housing 12.

[0073] The tag 13 is mounted after mounting the inner shell 11. The outer shell 10 is then mounted to enclose the tag 13 in the housing 12. The mounting is carried out at room temperature. Prior to mounting, the ring may undergo a step performed at high temperature, for example by welding.

[0074] The screw 20 passes between the two parts of the inner shell 11. The screw 20 passes through the protrusion 41, the label 13 and the outer shell 10. The screw 20 holds and fastens the outer shell 10 to the ring body 2 together with the nut 21, if appropriate. The tolerances are selected so that the inner shell 11 is also held securely. The label 13 is protected.

[0075] The outer shell 10 and the inner shell 11 give the label 13 an arc shape. The outer shell 10 is preferably opaque. The outer shell 10 is composed of precious, exquisite or decorative gemstones. The gemstone is selected from: diamond, ruby, sapphire, beryl (especially emerald, aquamarine, golden beryl or morganite), tourmaline (especially green tourmaline, red tourmaline, Paraiba tourmaline, blue tourmaline or black tourmaline), topaz (especially sky blue topaz, Swiss blue topaz or London blue topaz), garnet (especially demantoid, iron aluminum garnet, tsavorite, spessartine, grossular, iron aluminum garnet or pyrope), quartz (especially cat's eye quartz, eagle's eye quartz, tiger's eye quartz, ox's eye quartz, aventurine, amethyst, citrine, green crystal, pink quartz, blue quartz, red quartz or smoky quartz), chalcedony (especially magenta, chrysoprase, quartz crystal ... agate, chrysoprase, carnelian, onyx, sardisite or pietersite), jasper (especially red, blood or sunstone), feldspar (especially amazonite, moonstone, labradorite or sunstone), opal (especially fire, beauty or precious opal), jade (especially jadeite, jadeite, nephrite or amethyst), peridot, tanzanite, iolite, zircon, kyanite, spinel, rock crystal, kunzite, sodalite, azurite, turquoise, rhodonite, rhodochrosite, malachite, chrysocolla, sugilite, chrysoberyl, andalusite, diopside, magnesia schist, lapis lazuli, nacre, coral, amber, petrified wood.

[0076] The housing 10 may also be made of leather.

[0077] After installation, the jewelry 1 comprises: a ring body 2 made of a precious material capable of attenuating or forming a shield for shielding the transmission of radio waves towards the antenna 15 or from the antenna 15 towards the external environment; an inner shell 11 and an outer shell 10 made of one or more materials that allow the passage of radio waves in the usual frequency range, especially for RFID or NFC. The tag 13 is operational.

The housing 12 is semicircular. The jewelry 1 includes a flexible tag 13 arranged in the housing 12. The tag 13 includes an electronic chip 14 and an antenna 15 arranged around the electronic chip 14.

[0084] The jewelry 1 comprises a screw 20 that fixes the outer shell 10 and the inner shell 11 together. In the illustrated embodiment, a nut 21 is also provided, which forms a bolt with the screw 20. The screw 20 has a head with a small thickness. The screw 20 is assembled into the ring body 2. The nut 21 is assembled from the outside. The screw 20 engages with the nut 21. The screw and the nut can be made of the same material as the dial 52, or selected from the same group of materials. The nut can also include precious, exquisite or decorative gemstones.

[0085] The housing 10 is a one-piece product. The housing 10 covers the opening 55 on the outside, in other words, opposite the inner surface 53. The housing 10 may also partially cover the arms 58, 59. The housing 10 is arc-shaped. The thickness of the housing 10 is between 1.0 mm and 3.0 mm.

[0086] The circumferential free end 30 of the housing 10 meets the substantially radial surface 57. The circumferential free end 30 of the housing 10 may be provided with straight edges to cooperate with the recesses. The housing 10 has a free outer surface 31 for artistic design or to support another component. The housing 10 has an inner surface 32 that defines the shell 12. The inner surface may be recessed relative to the cylinder forming the geometric envelope of the housing 10 to increase the volume of the shell 12. Two ribs 33 may be formed at the boundaries of the recess. These ribs may meet the recesses of the branches 58, 59.

[0087] See [ Figure 6 ], a through hole 34 is formed in the housing 10. Alternatively, the hole is a blind threaded opening provided on the inner surface 32 for engagement with the screw 20. The hole 34 is radial. The hole 34 is arranged in the center of the housing 10. On the outside, the hole 34 may have a countersunk hole 44.

[0088] The housing 10 is made of a material selected from the group consisting of precious gemstones, fine gemstones, decorative gemstones, and leather.

[0089] The inner shell 11 is here made of two parts, each of which is made in one piece. In the embodiment shown, the two parts are symmetrical with respect to a plane passing through the axis. Alternatively, the inner shell 11 is a one-piece piece. The inner shell 11 covers the opening 5 on the inside, in other words, the inner surface 53. The inner shell 11 is inserted between the branches 58, 59. The thickness of the inner shell 11 is between 1.0 mm and 2.0 mm.

[0090] The inner shell 11 is arc-shaped. The circumferential free end 30 of the inner shell 11 is connected to the edge of the opening 55. The inner shell 11 has an outer surface 35 that defines the housing 12. The outer surface 35 can be substantially smooth. The cross section of the outer surface 35 along the plane passing through the axis can be a straight line. The outer surface 35 is at least partially away from the inner surface 32. The inner shell 11 has an inner surface 36 that is flush with the inner surface 53 of the dial 52. The inner shell 11 has an edge that is connected to the inner edge of the opening 55. Along the longitudinal axis direction, the inner shell 11 is longer than the aperture of the opening 55 and occupies a larger angular sector. Therefore, the inner shell 11 is located on the edge of the opening 55 in the installed state, especially on most of the edge, preferably on the entire edge, except for being installed in a precise manner where appropriate. The inner shell 11 is installed on the dial 52 from the outside (especially according to radial translation).
