FINE JEWELRY WITH PAYMENT MEANS

Description

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

[0002] The Applicant has observed profound changes in the field of fine jewelry with regard to materials and forms. However, one constant remains: fine jewelry is afunctional in that it lacks any technical function for the wearer. A piece of jewelry may be equipped with mechanisms such as a clasp, the purpose of which is to fasten or secure the jewelry. These are functions subordinate to the ornamental function.

[0003] US11083256 proposes a ring with a hollow cross-sectional inner surface to form an annular channel. An NFC transponder, comprising a coil-shaped antenna etched onto a cylindrical flexible substrate, is installed within this annular channel. A resin seal encapsulates both the NFC transponder and the flexible substrate. However, this ring model is manufactured in several sizes to accommodate different finger diameters. Each size requires a specific resin seal, NFC transponder, and flexible substrate. This significantly complicates manufacturing. Furthermore, the signal emitted by the antenna within the ring's internal annular channel is poorly transmitted. This imposes constraints on the choice of ring material, ring shape, and dimensions due to the size of the NFC transponder and the substrate. The NFC transponder's antenna encircles the ring.However, the choice of material, shape, and dimensions is of great importance for a piece of jewelry and falls within the realm of artistic creation. Imposing such constraints is therefore a significant drawback. WO2022 / 084886A1 describes a piece of jewelry according to the preamble of claim 1.

[0004] The Applicant designed and developed a piece of jewelry with a means of payment independent of the size of the jewelry and respecting the freedom of ornamental design of the jewelry while offering a quality transmission.

[0005] The invention proposes a piece of jewelry, in particular a ring or bracelet or pendant, comprising a body having an inner surface, an outer surface and a light passing through the body from the inner surface to the outer surface, the body being made of a material chosen from: gold, silver, platinum, titanium, palladium, steel or vermeil; an outer shell forming a part of the outer surface of the piece of jewelry and in contact with the body, the outer shell being made of a material chosen from: precious stone, semi-precious stone, ornamental stone, leather; an inner shell forming a part of the inner surface and in contact with the body, a closed housing being provided between the outer shell and the inner shell substantially at the right of or in the light, the housing being in the shape of an arc of a circle, the inner shell being made of a material chosen from: precious stone, semi-precious stone, ornamental stone, leather;A flexible tag housed within the casing, comprising an electronic chip and an antenna arranged around the electronic chip, characterized in that a screw holds the outer and inner casings together. The body can be made from a wide range of materials, including precious metals. The tag's dimensions are consistent across different sizes within a single jewelry design, and across multiple jewelry designs. The tag is concealed within the jewelry, thus offering a lack of visual and aesthetic impact.

[0006] In one embodiment, two lights are provided passing through the body from the inner surface to the outer surface, the two lights being separated by a crossbar forming part of the ring body. Signal transmission is preserved and assembly is simplified.

[0020] In the field of jewelry, respecting the artistic freedom of the creator is fundamental. Conventionally, artistic freedom was tempered by the mechanical limitations of the materials used. The pursuit of bolder forms led to the development of more resistant materials. Simultaneously, the use of original, often fragile, materials was also desired.

[0021] Then, the miniaturization of communication electronics made its incorporation into jewelry feasible. However, the requirements for data rate and transmission quality are high, especially since a high-quality piece of jewelry cannot be satisfied with low-end transmission. Taking into account the analysis she had thus conducted, the Applicant developed a piece of jewelry adapted to high-performance radio communication electronics. The Applicant identified several difficulties. The metal constituting the majority of the volume of a piece of jewelry generally acts as a poor transmitter of radio waves, or even as a shield that significantly attenuates the waves.

[0022] Furthermore, jewelry sometimes contains other non-metallic materials. The Plaintiff sought to utilize these non-metallic materials to enhance radio wave transmission despite the use of precious metals.

[0023] Thus, the jewelry piece 1 has a general annular shape. It may be a ring. The jewelry piece 1 comprises a ring body 2. The ring body 2 is structural in that it gives the jewelry piece 1 its general shape. The ring body 2 has a bore 3 or inner surface, an outer surface 4, and a span 5 through the ring body 2 from the bore 3 to the outer surface 4. The edges 6 of the ring body 2 have a free annular shape. Here, the edges 6 of the ring body 2 are rounded. In other words, the ring body 2 has a common arm and two arms 8, 9 axially distant along the axis of the ring, the two distant arms joining the common arm at each of their ends, see [ Fig.3 ].

[0024] In the illustrated embodiment, the ring body 2 is a single-piece annular ring. The ring body 2 is symmetrical with respect to a plane normal to the axis of the bore 3. The ring body 2 has a first solid portion, shown in the lower part of the figures, and a second portion, shown in the upper part of the figures. The first portion has a variable thickness in the radial direction, with a minimum at a distance from the second portion. The second portion comprises the two axially spaced arms 8 and 9 that define the aperture 5. Each arm 8 and 9 has an arc shape. In cross-section, the arm 8 and 9 is rounded towards the edge 6 and towards the bore 3. Opposite the bore 3, the cross-section of the arm 8 and 9 is straight, specifically parallel to the axis of the bore 3. Towards the aperture 5, the cross-section of the arm 8 and 9 is straight, for example, oriented radially.At least one step may be provided to facilitate the positioning and retention of other components below. The step is formed on the edge of the aperture opposite bore 3 and edge 6, either continuously or discontinuously, for example on arms 8, 9.

[0025] The branches 8 and 9 have a thickness less than that of the first portion, at least in the vicinity of said first portion. A substantially radial surface 7 is thus formed between the first and second portions on each side of the ring body 2. A concavity 17 can be formed in said substantially radial surface 7. The concavity 17 follows the shape of the ring body 2. The concavity 17 is blind.

[0026] The body of ring 2 can be made of a material that blocks the transmission of radio waves. The body of ring 2 is made of a material chosen from: gold, silver, platinum, palladium, vermeil, titanium, steel.

[0027] The jewelry piece 1 includes an outer shell 10 forming part of the outer surface 4 of the jewelry piece 1 and in contact with the ring body 2. The jewelry piece 1 includes an inner shell 11 forming part of the surface of the bore 3 and in contact with the ring body 2. A housing 12, closed in the mounted state, is provided between the outer shell 10 and the inner shell 11, substantially aligned with or within the opening 5. The housing 12 is arc-shaped. The jewelry piece 1 includes a flexible tag 13 disposed in the housing 12. The tag 13 includes an electronic chip 14 and an antenna 15 arranged around the electronic chip 14.

[0028] The jewelry component 1 includes a screw 20 that holds together the outer shell 10 and the inner shell 11. In the embodiment shown, a nut 21 is also provided, forming a bolt with the screw 20. The screw 20 has a thin head. The screw 20 is inserted from the inside of the ring body 2. The nut 21 is inserted from the outside. The screw 20 engages with the nut 21. The screw and the nut may be made of the same material as the ring body 2 or selected from the same group of materials. The nut may also include a precious, semi-precious, or ornamental stone.

[0029] The outer shell 10 is a single piece. The outer shell 10 covers the aperture 5 on the outside, in other words, opposite the bore 3. The outer shell 10 may also partially cover the arms 8 and 9. The outer shell 10 has an arc shape. The outer shell 10 has a thickness between 1.0 and 3.0 mm.

[0030] The circumferential free ends 30 of the outer shell 10 come into contact with the substantially radial surfaces 7. The circumferential free ends 30 of the outer shell 10 may be provided with protrusions to project into the concavities 17. The outer shell 10 has a free outer surface 31 for artistic design or to support another component. The outer shell 10 has an inner surface 32 delimiting the housing 12. The inner surface may be recessed relative to a cylinder forming a geometric envelope of the outer shell 10 to increase the volume of the housing 12. Two ribs 33 may be formed along the edge of said recess. The ribs may be in contact with said step of the branches 8, 9.

[0031] A hole 34, see [ Fig.6 A through hole is provided in the outer shell 10. Alternatively, the hole is blind and threaded, opening onto the inner surface 32 for engagement with the screw 20. The hole 34 is radial. The hole 34 is located in the center of the outer shell 10. On the outside, the hole 34 may have a counterbore 44.

[0032] The outer shell 10 is made of a material chosen from: precious stone, semi-precious stone, ornamental stone, leather.

[0033] The inner shell 11 is here made in two parts, each being a single piece. The two parts are symmetrical with respect to a plane passing through the axis in the embodiment shown. Alternatively, the inner shell 11 is a single piece. The inner shell 11 covers the opening 5 on the inner side, in other words, on the side of the bore 3. The inner shell 11 is inserted between the arms 8 and 9. The inner shell 11 has a thickness of between 1.0 and 2.0 mm.

[0034] The inner shell 11 has an arc shape. The circumferential free ends 30 of the inner shell 11 come into contact with the edge of the aperture 5. The inner shell 11 has an outer surface 35 delimiting the housing 12. The outer surface 35 may be substantially smooth. The outer surface 35 may be straight in cross-section along a plane passing through the axis. The outer surface 35 is at least partially separated from the inner surface 32. The inner shell 11 has an inner surface 36 flush with the bore 3 of the ring body 2. The inner shell 11 has edges in contact with the inner edges of the aperture 5. The inner shell 11 is longer, along the longitudinal axis, than the aperture of the aperture 5 and occupies a larger angular sector. Thus, the internal shell 11 rests in the assembled state on the edge of the light 5, in particular on the majority of the edge, preferably on the entire edge except, where appropriate, at specific points.The mounting of the inner shell 11 onto the ring body 2 is carried out from the outside, in particular by means of a radial translation.

[0035] Once mounted on the ring body 2, the outer surface 35 is flush with the concavities 17, see [ Fig.4 ]. The inner surface 32 is flush with the bore 3, see [ Fig.7 The branches 8, 9 extend axially beyond the inner shell 11, see figures 4 And 5 .

[0036] The inner shell 11 is made of a material chosen from: precious stone, semi-precious stone, ornamental stone, leather.

[0037] In the embodiment shown, the ring body 2 includes a spacer 40. The spacer 40 is oriented longitudinally. The spacer 40 is parallel to the axis. The spacer 40 connects the arm 8 and the arm 9. The spacer 40 is mounted approximately in the middle of the slot 5. The spacer 40 is located at the top of the ring body 2. The spacer 40 is flush with the bore 3, see [ Fig.2 The spacer 40 has a rectangular cross-section with a bulge 41 in the middle of said spacer 40. The bulge 41 is traversed by a hole 42. The screw 20 is inserted into the hole 42, see [ Fig.2 ], for fixing the components of the jewelry piece 1. The bulge 41 extends laterally relative to the spacer 40, i.e., circumferentially relative to the ring body 2. The bulge 41 is flush with the bore 3, see [ Fig.2 ]. The bulge 41 is slightly radially projecting relative to branches 8,9, see [ Fig.2 ] and slightly radially recessed relative to the outer surface 35 of the inner shell 11.

[0038] In another embodiment, the ring body 2 has no spacer. The inner shell is a single piece. The screw then tightens the outer and inner shells, the inner shell being mounted from the inside. The screw can also engage within the ring body, for example in one of the arms 8, 9 or in both arms 8, 9.

[0039] The tag 13 has a flat, rectangular shape with rounded corners. The electronic chip 14 protrudes from the rest of the tag 13. The inner surface 32 of the outer shell 10 has a recess corresponding to the distance from the free ends 30 and the ribs 33. The electronic chip 14 is offset from the center of the tag 13. A through hole for the screw 20 is provided in the center of the tag 13. The antenna 15 is wound flat around the electronic chip 14 and around the hole. The tag has a body made of a material flexible enough to conform to the curvature of the housing 12.

[0040] The tag 13 is mounted after the inner shell 11 is fitted. The outer shell 10 is then fitted to enclose the tag 13 in the housing 12. The assembly is carried out at room temperature. Before assembly, the ring body may undergo high-temperature processing, for example, by welding.

[0041] The screw 20 passes between the two parts of the inner shell 11. The screw 20 passes through the bulge 41, the tag 13, and the outer shell 10. The screw 20, possibly with the nut 21, holds and tightens the outer shell 10 against the ring body 2. The tolerances are chosen so that the inner shell 11 is also held firmly. The tag 13 is protected.

[0042] The outer shell 10 and inner shell 11 give the tag 13 its arched shape. Preferably, the outer shell 10 is opaque. The outer shell 10 consists of a precious, semi-precious, or ornamental stone. The said stone is chosen from among: diamond, ruby, sapphire, beryl (including emerald, aquamarine, heliodor or morganite), tourmaline (including verdelite, rubellite, paraiba, indicolite or schorl), topaz (including topaz, sky blue, Swiss blue topaz, or London blue topaz), garnet (including demantoid garnet, almandine garnet, tsavorite garnet, spessartine garnet, hessonite garnet, rhodolite garnet or pyrope garnet), quartz (including cat's eye quartz, hawk's eye quartz, tiger's eye quartz, bull's eye quartz, aventurine, amethyst, citrine, prasiolite, rose quartz, blue quartz, red quartz or smoky quartz), chalcedony (including agate, chrysoprase, carnelian, onyx, sardonyx or pietersite), jasper (especially red jasper, blood jasper or heliotrope jasper),Feldspars (including amazonite, moonstone, labradorite, or sunstone), opal (including fire opal, cacholong, or precious opal), jade (including jadeite jade, nephrite jade, or charoite), peridot, tanzanite, iolite, zircon, kyanite, spinel or rock crystal, kunzite, azurite, sodalite, turquoise, rhodonite, rhodochrosite, malachite, chrysocolla, sugilite, chrysoberyl, andalusite, diopside, pinolite, lapis lazuli, mother-of-pearl, coral, amber, petrified wood.

[0043] The outer shell 10 can also be made of leather.

[0044] Once assembled, the jewelry piece 1 consists of the ring body 2 made of a precious material capable of attenuating or shielding the transmission of waves to the antenna 15 or from the antenna 15 to the external environment, and the inner shell 11 and outer shell 10 made of one or more materials that allow the transmission of waves in the usual frequency ranges, particularly for RFID or NFC. The tag 13 is operational.

[0045] In the method of implementation of figures 9 à 14 The jewelry piece 1 has a general closed ring shape. It may be a bracelet. The jewelry piece 1 comprises a dial 52 or body and a bracelet body 73. The bracelet body 73 may be flexible, for example, made of leather, plant-based material, or fabric; or rigid and hinged, for example, made of a metal chosen from: gold, silver, platinum, titanium, palladium, vermeil, or steel; or made of a semi-rigid material, particularly a metal. The bracelet body 73 is, in this case, fitted with a clasp 74, for example, a buckle and pin clasp.

[0046] The dial 52 has an arched shape. The dial 52 has an inner surface 53, an outer surface 54, and a light 55 passing through the dial 52 from the inner surface 53 to the outer surface 54. The edges 56 of the dial 52 have a freeform shape. Here, the edges 56 of the dial 52 are rounded. The dial 52 has, in projection, a rectangular shape with two arms 58, 59 axially separated along the axis of the jewelry piece 1, the two arms 58, 59 being connected to each other. The two arms 58, 59 are longitudinal. The two arms 58, 59 are connected by transverse arms 60, 61. The transverse arms 60, 61 are, here, straight. The transverse arms 60, 61 are profiled. The transverse branches 60, 61 connect the ends of branches 58, 59.

[0047] The dial 52 is symmetrical here with respect to a plane normal to the axis of the jewelry piece 1. The two axially spaced arms 58, 59 define the aperture 55. Each arm 58, 59 has an arc shape. In cross-section, the arm 58, 59 is rounded towards the edge 56 and towards the inner surface 53. Opposite the inner surface 53, the cross-section of the arm 58, 59 is straight, specifically parallel to the axis of the inner surface 53. Towards the aperture 55, the cross-section of the arm 58, 59 is straight, for example, oriented radially. A step may be provided to facilitate the positioning and retention of other components below. The step is provided on the edge of the light 55 opposite the inner surface 53 and the edge 56, in a continuous or discontinuous manner, for example on the branches 58, 59.

[0048] The arms 58 and 59 have a substantially constant thickness. These arms form a first portion of the dial 52 and are connected by a second portion of the dial 52. The second portion of the dial 52 comprises two crossbars symmetrical with respect to a median plane. A substantially radial surface 57 is thus formed between the first and second portions on each side of the dial 52.

[0049] Dial 52 can be made of a material that blocks the transmission of radio waves. Dial 52 is made of a material chosen from: gold, silver, platinum, palladium, vermeil, titanium, or steel.

[0050] The jewelry piece 1 includes an outer shell 10 forming part of the outer surface 54 of the jewelry piece 1 and in contact with the dial 52. The jewelry piece 1 includes an inner shell 11 forming part of the inner surface 53 and in contact with the dial 52. A housing 12, closed in the mounted state, is provided between the outer shell 10 and the inner shell 11, substantially aligned with or within the opening 55. The housing 12 is arc-shaped. The jewelry piece 1 includes a flexible tag 13 disposed in the housing 12. The tag 13 includes an electronic chip 14 and an antenna 15 arranged around the electronic chip 14.

[0051] The jewelry component 1 includes a screw 20 that holds together the outer shell 10 and the inner shell 11. In the embodiment shown, a nut 21 is also provided, forming a bolt with the screw 20. The screw 20 has a thin head. The screw 20 is inserted from the inside of the ring body 2. The nut 21 is inserted from the outside. The screw 20 engages with the nut 21. The screw and nut may be made of the same material as the dial 52 or selected from the same group of materials. The nut may also include a precious, semi-precious, or ornamental stone.

[0052] The outer shell 10 is a single piece. The outer shell 10 covers the aperture 55 on the outside, that is, opposite the inner surface 53. The outer shell 10 may also partially cover the arms 58, 59. The outer shell 10 has an arc shape. The outer shell 10 has a thickness of between 1.0 and 3.0 mm.

[0053] The circumferential free ends 30 of the outer shell 10 come into contact with the substantially radial surfaces 57. The circumferential free ends 30 of the outer shell 10 may have straight edges to cooperate with the step. The outer shell 10 has a free outer surface 31 for artistic design or to support another component. The outer shell 10 has an inner surface 32 delimiting the housing 12. The inner surface may be recessed relative to a cylinder forming a geometric envelope of the outer shell 10 to increase the volume of the housing 12. Two ribs 33 may be formed along the edge of said recess. The ribs may be in contact with said step of the branches 58, 59.

[0054] A hole 34, see [ Fig.6 A through hole is provided in the outer shell 10. Alternatively, the hole is blind and threaded, opening onto the inner surface 32 for engagement with the screw 20. The hole 34 is radial. The hole 34 is located in the center of the outer shell 10. On the outside, the hole 34 may have a counterbore 44.

[0055] The outer shell 10 is made of a material chosen from: precious stone, semi-precious stone, ornamental stones, leather.

[0056] The inner shell 11 is here made in two parts, each being a single piece. The two parts are symmetrical with respect to a plane passing through the axis in the embodiment shown. Alternatively, the inner shell 11 is a single piece. The inner shell 11 covers the opening 5 on the inner side, in other words, on the side of the inner surface 53. The inner shell 11 is inserted between the arms 58, 59. The inner shell 11 has a thickness of between 1.0 and 2.0 mm.

[0057] The inner shell 11 has an arc shape. The circumferential free ends 30 of the inner shell 11 come into contact with the edge of the aperture 55. The inner shell 11 has an outer surface 35 delimiting the housing 12. The outer surface 35 may be substantially smooth. The outer surface 35 may be straight in section along a plane passing through the axis. The outer surface 35 is at least partially separated from the inner surface 32. The inner shell 11 has an inner surface 36 flush with the inner surface 53 of the dial 52. The inner shell 11 has edges in contact with the inner edges of the aperture 55. The inner shell 11 is longer, along the longitudinal axis, than the aperture of the aperture 55 and occupies a larger angular sector.Thus, the inner shell 11, in its mounted state, rests on the edge of the aperture 55, specifically on most of the edge, preferably on the entire edge except, where applicable, at specific points. The inner shell 11 is mounted onto the dial 52 from the outside, specifically via a radial translation.

[0058] Once mounted on the dial 52, the outer surface 35 is flush with the step, see [ Fig.12 The inner surface 32 is flush with the inner surface 53, see figures 12 & 13 Branches 58 and 59 extend axially beyond the inner shell 11, see figures 9 And 10 .

[0059] The inner shell 11 is made of a material chosen from: precious stone, semi-precious stone, ornamental stone, leather.

[0060] In the embodiment shown, the dial 52 includes a spacer 40. The spacer 40 is oriented longitudinally. The spacer 40 is parallel to the axis. The spacer 40 connects the arm 58 and the arm 59. The spacer 40 is mounted approximately in the middle of the aperture 55. The spacer 40 is positioned at the top of the dial 52. The spacer 40 is flush with the inner surface 53, see [ Fig.12 The spacer 40 has a rectangular cross-section with a bulge 41 in the middle of said spacer 40. The bulge 41 is traversed by a hole 42. The screw 20 is inserted into the hole 42, see figures 10 And 11 , for fixing the components of the jewelry piece 1. The bulge 41 extends in width relative to the spacer 40, i.e., circumferentially relative to the dial 52. The bulge 41 is flush with the inner surface 53, see [ Fig.11 ]. The bulge 41 is flush with an outer surface of branches 58, 59, see [ Fig.10 ].

[0061] Tag 13 is similar to the tag in the previous embodiment, but with a lesser curvature. Tag 13 has a body made of a material flexible enough to adapt to the curvature of the housing 12.

[0062] The tag 13 is mounted after the inner shell 11 is fitted. The outer shell 10 is then fitted to enclose the tag 13 in the housing 12. The assembly is carried out at room temperature. Before assembly, the dial may undergo high-temperature processes, for example, by soldering.

[0063] The screw 20 passes between the two parts of the inner shell 11. The screw 20 passes through the bulge 41, the tag 13, and the outer shell 10. The screw 20, possibly with the nut 21, secures and tightens the outer shell 10 against the dial 52. The tolerances are chosen so that the inner shell 11 is also held firmly. The tag 13 is protected. The screw and nut may be made of the same material as the ring body 2 or selected from the same group of materials. The nut may also include a jewel.
