Description

[Technical field]

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

[0002] The applicant has observed a profound evolution in the field of fine jewelry in terms of materials and shapes. Nevertheless, a certain fact is that fine jewelry is non-functional, meaning that it does not have any technical function for the wearer of said jewelry. Jewelry may be provided with mechanisms such as clasps intended to set or hold the jewelry in place. These are functions that are secondary to the decorative function.

[0003] US Patent No. 11083256 provides a ring whose inner surface is recessed in cross section to form an annular channel. An NFC transponder, which includes an antenna in the form of a coil etched on a cylindrically shaped flexible substrate, is placed in the annular channel. A resin seal encapsulates the NFC transponder and the flexible substrate. However, the ring model is manufactured in several sizes for different finger diameters. Each size corresponds to a specific resin seal, NFC transponder, and flexible substrate. This substantially complicates the manufacturing. In addition, the signal radiated by the antenna placed in the inner annular channel of the ring is hardly transmitted. This imposes constraints on the choice of material constituting the ring, on the shape of the ring and its dimensions, due to the dimensions of the NFC transponder and the substrate. The antenna of the NFC transponder goes around the ring. However, the choice of material, shape and dimensions is very important for an item of jewelry and concerns artistic creation. Therefore, imposing such constraints is a major drawback. Summary of the Invention [Problem to be solved by the invention]

[0004] The applicant has designed and developed a piece of jewellery with a payment means that is independent of the size of the gemstone and provides high quality transparency whilst accommodating the freedom of decorative design of the jewellery. [Means for solving the problem]

[0021] In the field of jewellery, respect for the artistic freedom of the creator of the object is fundamental. Traditionally, artistic freedom has been strengthened by the mechanical limitations of the material in which it is implemented. The search for the measure of shape has led to the development of stronger materials. At the same time, the implementation of the original material, which is often weak, is also desired.

[0022] The miniaturization of communication electronics then makes it possible to consider their incorporation into jewelry. Nevertheless, the requirements for data throughput and transmission quality are high, so that high-quality jewelry cannot compete with low-end transmission. Taking into account the analysis thus carried out, the applicant has developed jewelry suitable for high-performance wireless communication electronics. The applicant has identified several difficulties: the metals that make up most of the volume of the jewelry generally form poor radio wave transmitters and form shields that attenuate the waves considerably.

[0023] Additionally, jewelry may contain other non-metallic materials, which applicant seeks to exploit to their advantage in the transmission of radio waves, despite the use of precious metals.

[0024] Thus, the jewellery 1 has a general annular shape. It may consist of a ring. The jewellery 1 comprises a ring body 2. It is the structural meaning that gives the jewellery 1 its general shape. The ring body 2 has a bore 3 or inner surface, an outer surface 4 and an opening 5 that passes through the ring body 2 from the bore 3 to the outer surface 4. The edge 6 of the ring body 2 has a free annular shape. In this case, the edge 6 of the ring body 2 is rounded. In other words, the ring body 2 has a common branch and two branches 8, 9 axially spaced apart according to the axis of the ring, the two separate branches joining the common branch at each of their ends (see FIG. 3).

[0025] In the illustrated embodiment, the ring body 2 is annular and made in one piece. The ring body 2 is symmetrical with respect to a plane perpendicular to the axis of the bore 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 first part has a variable radial thickness that is minimum at a distance from the second part. The second part comprises two axially spaced branches 8, 9 that define the opening 5. Each branch 8, 9 is arc-shaped. In cross section, the branches 8, 9 have a cross section that is rounded towards the edge 6 and towards the bore 3. On the opposite side of the bore 3, the cross section of the branches 8, 9 is here linear, in particular parallel to the axis of the bore 3. Towards the opening 5, the parts of the branches 8, 9 are linear and, for example, oriented radially. At least one recess can be provided to facilitate the positioning and retention of the other elements below. The recesses are formed in the edge of the opening opposite the bore 3 and edge 6, either continuously or discontinuously, for example at the bifurcations 8,9.

[0026] The branches 8,9 have a thickness, at least in the vicinity of said first portion, which is smaller than the thickness of the 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 recess 17 may be formed in said substantially radial surface 7. The recess 17 fits the shape of the ring body 2. The recess 17 is blind.

[0027] The ring body 2 may be made of a material that is an obstacle to the transmission of radio waves. The ring body 2 is made of a material selected from gold, silver, platinum, palladium, vermeil, titanium, and steel.

[0028] The jewellery 1 includes an outer shell 10 which forms part of the outer surface 4 of the jewellery 1 and which is in contact with the ring body 2. The jewellery 1 includes an inner shell 11 which forms part of the surface of said bore 3 and which is in contact with the ring body 2. A housing 12 which is closed in the worn state is formed between the outer shell 10 and the inner shell 11 substantially aligned with or within the opening 5. The housing 12 is semicircular. The jewellery 1 includes a flexible tag 13 disposed within the housing 12. The tag 13 includes an electronic chip 14 and an antenna 15 disposed around the electronic chip 14.

[0029] The jewelry item 1 includes a screw 20 that holds the outer shell 10 and the inner shell 11 together. In the embodiment shown, a nut 21 is provided that forms a bolt with the screw 20. The screw 20 has a thin head. The screw 20 is fitted from the inside of the ring body 2 and the nut 21 is fitted 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 may be selected from the same group of materials. The nut may also include a precious, fine or decorative gemstone.

[0030] The outer shell 10 is formed in one piece. It covers the outside, in other words the opening 5 opposite the bore 3. It may also partially cover the branches 8, 9. The outer shell 10 is arc-shaped. It has a thickness comprised between 1.0 mm and 3.0 mm.

[0031] The free circumferential end 30 of the outer shell 10 is substantially in contact with the radial surface 7. The free circumferential end 30 of the outer shell 10 may be provided with a protrusion projecting into the recess 17. The outer shell 10 has an outer surface 31 free for artistic design or for supporting another member. The outer shell 10 has an inner surface 32 defining the housing 12. The inner surface may be recessed relative to a cylinder forming the geometric envelope of the outer shell 10 in order to increase the volume of the housing 12. Two ribs 33 may be formed at the border of said recess. The ribs may be in contact with said indentations of the branches 8, 9.

[0032] A through hole 34 (see FIG. 6) is formed in the outer shell 10. Alternatively, the hole is a blind threaded opening on the inner surface 32 for engaging the screw 10. 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.

[0033] The outer shell 10 is made from a material selected from precious gemstones, fine gemstones, ornamental gemstones, and leather.

[0034] The inner shell 11 is here formed in two parts, each of which is formed in one 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 formed in one piece. The inner shell 11 covers the inside, that is to say the opening 5 on the side of the bore 3. The inner shell 11 is inserted between the branches 8, 9. The inner shell 11 has a thickness comprised between 1.0 mm and 2.0 mm.

[0035] The inner shell 11 is arcuate. The circumferential free end 30 of the inner shell 11 contacts the edge of the opening 5. The inner shell 11 has an outer surface 35 that defines the housing 12. The outer surface 35 may be substantially smooth. The outer surface 35 may be straight in a section according to a plane through the axis. The outer surface 35 is at least partially spaced from the inner surface 32. The inner shell 11 has an inner surface 36 that is flush with the bore 3 of the ring body 2. The inner shell 11 has an edge that contacts the inner edge of the opening 5. The inner shell 11 is longer and occupies a larger angular sector according to the longitudinal axis than the opening of the opening 5. In the mounted state, the inner shell 11 therefore rests on the edge of the opening 5, in particular over a large part of the edge, preferably over the entire edge except for a few points. The mounting of the inner shell 11 to the ring body 2 is performed from the outside, in particular according to a radial translation.

[0036] When mounted on the ring body 2, the outer surface 35 is flush with the recess 17 (see Figure 4) and the inner surface 32 is flush with the bore 3 (see Figure 7). The branches 8, 9 project axially from the inner shell 11 (see Figures 4 and 5).

[0037] The inner shell 11 is made from a material selected from precious gemstones, fine gemstones, ornamental gemstones and leather.

[0038] In the illustrated embodiment, the ring body 2 includes a spacer 40. The spacer 40 is oriented in the longitudinal direction. The spacer 40 is parallel to the axis. The spacer 40 connects the branch 8 and the branch 9. The spacer 40 is mounted substantially in the center of the opening 5. The spacer 40 is arranged in the upper part of the ring body 2, the spacer 40 being flush with the bore 3 (see FIG. 2). The spacer 40 has a rectangular cross section with a bulge 41 in the center of said spacer 40. The bulge 41 intersects with a hole 42. The screw 20 is inserted in the hole 42 to fasten the piece of jewelry 1 (see FIG. 2). The bulge 41 extends widthwise with respect to the spacer 40, i.e. circumferentially with respect to the ring body 2. The bulge 41 is flush with the bore 3 (see FIG. 2). The bulge 41 protrudes slightly radially relative to the lobes 8 , 9 (see FIG. 2) and is slightly recessed radially relative to the outer surface 35 of the inner shell 11 .

[0039] In another embodiment, the ring body 2 does not have a spacer. The inner shell is formed in one piece. The screw then tightens the outer shell and the inner shell, the inner shell being attached from the inside. The screw may also engage the ring body, for example in one or both of the branches 8, 9.

[0040] 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 outer shell 10 has a corresponding recess at a distance from the free end 30 and the rib 33. The electronic chip 14 is offset relative to the entire tag 13. A through hole for the screw 20 is formed in the center of the tag 13. The antenna 15 is wrapped flat around the electronic chip 14 and the hole. The tag has a body made of a material that is flexible enough to conform to the curvature of the housing 12.

[0041] The attachment of the tag 13 is performed after the attachment of the inner shell 11. The outer shell 10 is then attached so as to encapsulate the tag 13 within the housing 12. The mounting is performed at room temperature. Before mounting, the ring body can undergo a step performed at high temperature, for example by welding.

[0042] The screw 20 passes between the two parts of the inner shell 11. It penetrates the bulge 41, the tag 13 and the outer shell 10. The screw 20, together with a nut 21 if necessary, holds and tightens the outer shell 10 against the ring body 2. The tolerances are selected so that the inner shell 11 is also held tightly. The tag 13 is protected.

[0043] The outer shell 10 and the inner shell 11 give the tag 13 its arcuate shape. Preferably, the outer shell 10 is opaque. The outer shell 10 is made of a precious, fine, or decorative gemstone. The gemstone may be diamond, rubis, sapphire, beryl (particularly emerald, aquamarine, helidor, morganite), tourmaline (particularly verdelite, rubellite, parabatharmaline, indicolite, schorl), topaz (particularly sky blue topaz, Swiss blue topaz, London blue topaz), garnet (particularly demantoid garnet, almandine garnet, tsavorite garnet, spessartite garnet, hessonite garnet, rhodolite garnet, pyrope garnet), quartz (particularly cat eye quartz, falcon eye quartz, tiger quartz, blue eye quartz, aventurine, amethyst, citrine, prasiolite, pink quartz, blue quartz, red quartz, smoky quartz), chalcedony (particularly magenta quartz, rhodolite, citrine, prasiolite, pink quartz, blue quartz, red quartz, smoky quartz), chalcedony (particularly rhodolite, ... agate, chrysoprase, carnelian, onyx, sardistone, pietersite), jasper (especially red jasper, blood jasper, heliotropic jasper), feldspar (especially amazonite, moonstone, labradorite, sunstone), opal (especially fire opal, cacholong, noble opal), jade (especially jadeite, jadiite, nephrite jade, charoite), peridot, tanzanite, iolite, zircon, kyanite, spinel, rock crystal, kunzarite, azurite, turquoise, rhodonite, rhodochrosite, malachite, chrysocolla, sugulite, chrysoberyl, andalusite, diopside, pinolite, lapis lazuli, mother of pearl, coral, amber, silicified wood.

[0044] The outer shell 10 may also be made from leather.

[0045] When attached, the jewelry 1 consists of a ring body 2 made of a precious material capable of attenuating or forming a shield for the transmission of waves towards the antenna 15 or from the antenna 15 towards the external environment, and an inner shell 11 and an outer shell 10 made of one or more materials that allow waves to pass in the usual frequency ranges, in particular RFID or NFC. The tag 13 is operational.

[0046] In the embodiment of figures 9 to 14, the item of jewellery 1 has a closed ring like general shape. It may also consist of a bracelet. The jewellery 1 comprises a dial 52 or body and a bracelet body 73. The bracelet body 73 may be flexible, for example made of leather, vegetable material, fabric, or may be articulated and rigid, for example made of a metal chosen among gold, silver, platinum, titanium, palladium, burr or steel, or may be of a semi-rigid material, in particular metal. Here, the bracelet body 73 comprises a clasp 74, for example with a buckle and a tongue.

[0047] The dial 52 is arc-shaped. The dial 52 has an inner surface 53, an outer surface 54 and an opening 55 passing through the dial 52 from the inner surface 53 to the outer surface 54. The edge 56 of the dial 52 has a free shape. In this case, the edge 56 of the dial 52 is rounded. The dial 52 has a rectangular shape with two branches 58, 59 projecting and spaced apart axially according to the axis of the jewellery 1, the two branches 58, 59 being connected to each other. The two branches 58, 59 are longitudinal. The two branches 58, 59 are connected by lateral branches 60, 61. The lateral branches 60, 61 are linear here. The lateral branches 60, 61 are contoured. The lateral branches 60, 61 connect the ends of the branches 58, 59.

[0048] The dial 52 is here symmetrical with respect to a plane perpendicular to the axis of the jewellery 1. Two axially spaced branches 58, 59 define an opening 55. Each branch 58, 59 is arcuate. In cross section, the branches 58, 59 have a cross section that is rounded towards the edge 56 and towards the inner surface 53. Opposite the inner surface 53, the parts of the branches 58, 59 are here straight and in particular parallel to the axis of the inner surface 53. Towards the opening 55, the parts of the branches 58, 59 are straight and for example oriented radially. To facilitate the positioning and holding of other elements below, recesses can be provided. The recesses are formed continuously or discontinuously over the edge of the opening 55 opposite the inner surface 53 and the edge 56, for example on the branches 58, 59.

[0049] The branches 58, 59 have a substantially constant thickness. The branches 58, 59 form a first dial part 52 and are connected by a second dial part 52. The second dial part 52 comprises two cross members symmetrical with respect to a mid-plane. A substantially radial surface 57 is thus formed between the first and second parts on each side of the dial 52.

[0050] The dial 52 may be made of a material that is an impediment to the transmission of radio waves. The dial 52 is made of a material selected from gold, silver, platinum, palladium, glass, titanium, or steel.

[0051] The jewellery 1 includes an outer shell 10 that forms part of an exterior surface 54 of the jewellery 1 and that contacts a dial 52. The jewellery 1 includes an inner shell 11 that forms part of an interior surface 53 and that contacts a dial 52. A housing 12 that is closed when worn is formed between the outer shell 10 and the inner shell 11 substantially aligned with or within an opening 55. The housing 12 is semicircular. The jewellery 1 includes a flexible tag 13 disposed within the housing 12. The tag 13 includes an electronic chip 14 and an antenna 15 disposed about the electronic chip 14.

[0052] The jewellery item 1 includes a screw 20 that holds the outer shell 10 and the inner shell 11 together. In the embodiment shown, a nut 21 is also provided that forms a bolt with the screw 20. The screw 20 has a thin head. The screw 20 is fitted into the ring body 2 and the nut 21 is fitted 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 dial 52 or may be selected from the same group of materials. The nut may also include a precious, fine or decorative gemstone.

[0053] The outer shell 10 is integrally formed. It covers the opening 55 opposite the outer side, i.e. the inner side 53. It may also partially cover the arms 58, 59. The outer shell 10 is arc-shaped. The outer shell 10 has a thickness comprised between 1.0 mm and 3.0 mm.

[0054] The free circumferential end 30 of the outer shell 10 is in contact with a substantially radial surface 57. The free circumferential end 30 of the outer shell 10 may be provided with a straight edge for cooperating with a recess. The outer shell 10 has an outer surface 31 free for artistic design or for supporting another member. The outer shell 10 has an inner surface 32 defining the housing 12. The inner surface may be recessed relative to a cylinder forming the geometric envelope of the outer shell 10 in order to increase the volume of the housing 12. Two ribs 33 may be formed at the border of said hollow. The ribs may be in contact with said recesses of the branches 58, 59.

[0055] A through hole 34 (see FIG. 6) is formed in the outer shell 10. Alternatively, the hole is a blind threaded opening on the inner surface 32 for engaging 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.

[0056] The outer shell 10 is made from a material selected from precious gemstones, fine gemstones, ornamental gemstones, and leather.

[0057] The inner shell 11 is here formed in two parts, each of which is formed in one 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 formed in one 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 lobes 58, 59. The inner shell 11 has a thickness comprised between 1.0 mm and 2.0 mm.

[0058] The inner shell 11 is arcuate. The circumferential free end 30 of the inner shell 11 contacts the edge of the opening 55. The inner shell 11 has an outer surface 35 that defines the housing 12. The outer surface 35 may be substantially smooth. The outer surface 35 may be straight in a section through a plane passing through the axis. The outer surface 35 is at least partially spaced 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 contacts the inner edge of the opening 55. The inner shell 11 is longer and occupies a larger angular sector, according to its longitudinal axis, than the opening of the opening 55. In the mounted state, the inner shell 11 therefore rests in time on the edge of the opening 55, in particular over a large part of the edge, preferably over the entire edge, except where appropriate. The inner shell 11 is mounted on the dial 52 from the outside, in particular by radial translation.

[0059] Once attached to dial 52, outer surface 35 is flush with the recess (see FIG. 12). Inner surface 32 is flush with inner surface 53 (see FIGS. 12 and 13). Lobes 58, 59 project axially from inner shell 11 (see FIGS. 9 and 10).

[0060] The inner shell 11 is made from a material selected from precious gemstones, fine gemstones, ornamental gemstones and leather.

[0061] In the embodiment shown, the dial 52 includes a spacer 40. The spacer 40 is oriented in the longitudinal direction. The spacer 40 is parallel to the axis. The spacer 40 connects the branch 58 and the branch 59. The spacer 40 is mounted substantially in the center of the opening 55. The spacer 40 is arranged on 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 center of said spacer 40. The bulge 41 intersects with a hole 42. The screw 20 is inserted in the hole 42 to fasten the component of the jewellery 1 (see FIGS. 10 and 11). The bulge 41 extends widthwise with respect to the spacer 40, i.e. circumferentially with respect to the dial 52. The bulge 41 is flush with the inner surface 53 (see FIG. 11). Bulge 41 is flush with the outer surfaces of branches 58, 59 (see FIG. 10).

[0062] The tag 13 is similar to the tags of the previous embodiment, with a small curvature. The tag 13 has a body made of a material that is flexible enough to conform to the curvature of the housing 12.

[0063] The attachment of the tag 13 is performed after the attachment of the inner shell 11. The outer shell 10 is then attached so as to encapsulate the tag 13 within the housing 12.
