Definitions

  • the present invention relates to methods of manufacturing jewelry comprising one or more rows of stones and the jewelry obtained by these methods.
  • the technical sector of the invention is that of jewelry.
  • the objective of the present invention is to provide methods making it possible to make jewelry comprising numerous precious stones, in particular brilliants, set on a support of precious metal, in particular gold, to constitute jewelry, for example rivers of diamonds or diamond pavings comprising one or more rows of precious stones, very tight against each other, with intervals between stones of the order of 0.05 mm, which gives them a very high shine and a very beautiful aspect of area.
  • the housings of the stones must be machined with very great precision both in their dimensions and in their respective positions and taking into account the very great value of the precious stones the means of fixing of these must be very safe.
  • the fastening means must not be too visible externally so as not to harm the aesthetic appearance of the jewelry.
  • An object of the present invention is to provide methods for automatically prefabrication in the factory of precious metal supports, in particular gold, having various shapes, for example, plates, rings, bracelets, pendants etc ... , so that these supports are ready to receive one or more rows of precious stones, arranged very close to each other and so that the fixing of these stones is very easy to achieve by crimping and that the fixing claws are few visible on the outside.
  • the FR patent. 1.506.317 (H. FAVRE) describes a following process which stones are crimped onto a metal sheet by means of a crimping tool comprising several heads which penetrate into the metal by loosening a chip which they push against the stone to form a claw.
  • the FR patent. 80/04057 (DIAMOND. APPLICATIONS) describes industrial processes for the manufacture of jewels according to which the stones are put in place by snap-fastening of each stone in a housing thanks to an elastic deformation of metal claws.
  • each cylindrical housing is slightly less than the diameter of the circle circumscribed with the stone and a peripheral groove of triangular section whose diameter is cut at the periphery of each cylindrical housing and above the seat at the bottom of the groove is greater than the diameter of the circle circumscribed to said stone.
  • said metal bridges are cut with a milling cutter rotating at high speed around an axis which is successively placed above each points located in the center of the triangles formed by the centers of each group of three housings arranged in a triangle.
  • the metal bridges are cut with a milling cutter rotating at high speed around an axis which is successively placed above each point equidistant from the two centers of two neighboring housings and said cutter has a rounded internal cutting edge.
  • the invention makes it possible to obtain jewelry of the type comprising several rows of stones arranged in staggered rows which are encased in a precious metal support and which are crimped by claws which have undergone permanent deformation. :
  • each stone is surrounded by six claws and that each claw is located in the center of three stones and is common to these three stones.
  • Each claw has, in the part located above the seat on which the stone rests, the shape of a concave curvilinear triangular prism, the three side faces of which consist of three cylindrical sectors.
  • each claw comprises a hemispherical head or in the shape of a convex curvilinear trihedron, which surmounts a foot of smaller section, having the shape of a concave curvilinear triangle which is delimited by three sections of circular groove of section triangular which penetrate under said head.
  • the invention results in jewels which include a very dense paving of precious or semi-precious stones embedded in a precious metal support, for example rivers of diamonds.
  • the jewelry according to the invention comprises stones arranged, preferably, in staggered rows, each stone being set by six claws and each claw is situated in the center of three stones arranged at the vertices of a triangle and it is common to these three stones.
  • each stone is solidly set by six prongs while having a reduced total number of prongs, hence a higher density of brilliants and an improved aesthetic appearance.
  • the methods of manufacturing the jewelry according to the invention make it possible to prefabricate supports in the factory on machine tools with numerical control with the very high precision required both for the implantation of the housings of each stone and for the dimensions of these housings. , this precision being of the order of a hundredth of a millimeter.
  • the curvilinear triangle shape of the claws obtained by the machining process facilitates their permanent deformation by buckling and makes it possible to obtain a very safe crimping.
  • the method of crimping by buckling of the claws is particularly suitable for crimping fragile stones, for example emeralds or semi-precious stones, since the mechanical forces causing the buckling apply essentially to the claws without the stones being subjected to dangerous constraints.
  • a piece of jewelry according to the invention comprises a precious metal support 1, preferably gold.
  • This support can be for example a sheet which is filled with precious stones 2, contiguous, generally brilliants and which can then be used to make jewelry such as wedding rings, bracelets, pendants, brooches etc ...
  • the support 2 can also be constituted by the body of the jewel itself for example by a gold ring of alliance or bracelet or by a gold plate of pendant or any other jewel.
  • the jewelry according to the invention comprises one or more rows of contiguous stones 2; the interval between brilliants being of the order of 0.03 mm, so that the visible face is very shiny.
  • the stones 2 used to make these jewels are generally small stones. These stones are calibrated by passing through sieves whose meshes grow by 0.05 mm from one class to the next.
  • Each piece of jewelry is made up of stones belonging to specific particle size classes.
  • Each stone 2 is embedded in a housing 3 which has a conical seat 3b, on which the stone is supported.
  • the opening angle of this conical seat corresponds substantially to the angle a of the stones which is a well determined angle.
  • the figures represent embodiments in which the stones are identical and are staggered in parallel rows, the centers des.pierres being equidistant. ,
  • the same piece of jewelry can have rows of stones of different sizes.
  • the stones can be arranged in curved lines, for example in arcs of a circle.
  • the centers of the stones may not be equidistant.
  • the piece of jewelry can have one or more rows of stones.
  • the stones are advantageously arranged in staggered rows.
  • Each stone 2 is held in its housing by six claws 5 distributed regularly around its periphery.
  • Figures 2 to 5 show the successive stages of a first method of machining the support.
  • the support 1 3 which must be lined with stones, is placed on the work table of a numerically controlled machine tool which moves the table under a rotary cutter or a forest. This tool pierces through the support 2 of the rows of cylindrical-conical housings 3 equidistant and arranged in staggered rows.
  • Each housing has an external cylindrical bore 3a whose diameter is slightly greater than the upper limit of the particle size class chosen. For example, if diamonds having a diameter of between 1.10 mm and 1.15 mm have been chosen, bores 3a are machined having an external diameter of 1.15 mm with a tolerance of + 0.01 mm. The depth of the bores 3a is greater than the thickness of the head of the stones, so that when the diamonds are placed on the conical seat 3b, their upper face is located below the upper face of the support 1 as seen. in figure 1.
  • Each housing also has a conical seat 3b whose opening angle corresponds to the stone cutting angle.
  • Each housing 3 finally comprises a cylindrical bore 3c which can open onto the rear face of the support as shown in FIG. 2.
  • the bore 3c can be a blind bore. It suffices that the depth of the bore 3c is greater than the height of the stones.
  • the cylindrical-conical housings 3 are staggered and their respective positions are such that the metal bridges which separate two neighboring housings are very thin webs having a thickness of the order of 0.05 mm.
  • the machining of the housings 3 on a numerically controlled machine tool makes it possible to obtain the very high precision required in the dimension of the bores and in the implantation thereof. It also makes it possible to orient the tool perpendicular to the front surface of the support 1.
  • the staggered arrangement makes it possible to obtain a higher density of brilliants per unit of surface.
  • Figures 4 and 5 respectively show a partial plan view and a section along V-V of the support 1 during the second machining phase.
  • the support 1 is always arranged on the work table of a numerically controlled machine tool, on the tool holder from which a tool 6 is mounted which rotates around an axis x xl.
  • This tool is for example a cylindrical tungsten carbide bar having a head 6a which is rotated at very high speed. This head has two cutting edges parallel to the axis of rotation x xl.
  • the work table is moved to bring the axis x xl successively above each of the points 0 located in the center of each group of three housings 3 arranged in a triangle.
  • FIGS. 4 and 5 represent the tool 6 positioned so that its axis x xl passes through the point 0 located at the center of the triangle formed by the centers 0 1 , 0 2 and 0 3 of a group of three housings 3.
  • the points 0 ,, 0 2 and 0 3 are arranged at the vertices of an equilateral triangle whose point 0 is the center.
  • FIG. 4 shows the two concentric circles swept by the cutting head 6a.
  • the height of the head 6a is equal to the depth of the bores 3a, so that the tool 6 removes the three metal bridges interposed between the three housings 3a centered at 0 1 , 0 2 and 0 3 .
  • the external diameter of the head 6a is slightly greater than the distance separating the center 0 from the three sides of the equilateral triangle.
  • each center 0 a metal island having the shape of a curvilinear triangular prism whose lateral faces are concave and consist of three cylindrical sectors belonging to three neighboring bores 3a.
  • Figure 4 shows an intermediate step. For clarity, the metal islands 5a, 5b, 5c, 5d have been hatched in FIGS. 4 and 5.
  • a stone 2 is placed manually in each housing 2 which is pressed against the conical seat 3b.
  • the circle inscribed inside the six claws which surround a housing has a diameter greater than the diameter of the stone which therefore penetrates freely into its housing.
  • a crimping tool 7, shown in axial section in FIG. 5 is applied to this island.
  • This tool has the shape of a cylindrical punch ending in a hollow head 7a whose diameter is slightly greater than the diameter of the circle in which the islets 5 can fit.
  • the tool 7 is applied with sufficient force to cause the island 5 to burn, which undergoes permanent deformation, so that when all the islands have been deformed, each stone is set by six triangular claws formed by the islands 5.
  • Each claw 5 is common to three juxtaposed stones arranged at the vertices of a triangle.
  • Each claw which is surrounded by three stones with very little play, is deformed by buckling only in the axial direction because it is held laterally by the three stones which surround it and which prevent any deformation in bending.
  • Figures 6 to 9 show the successive stages of the machining of a support 1 in a variant of the method.
  • the first machining step is identical and is not shown.
  • the support 1 is pierced with several rows of housings 3 arranged in staggered rows.
  • Each housing 3 has an external bore 3a, a conical seat 3b and a counterbore 3c, the diameter of which is less than that of the bore 3a and which can be a blind bore.
  • the diameter of the external bore 3a is slightly less than the diameter of the stones.
  • the bores 3a have a diameter of 1.65 mm.
  • Figures 6 and 7 respectively show a partial plan view and a sectional view along VII-VII after the second machining step.
  • an internal groove 8 having a triangular profile which extends the slope of the conical seat 3b is cut at the periphery of each bore 3a and immediately above the seat 3b.
  • the diameter at the bottom of the groove 8 is greater than the external diameter of the stones. For example, for stones whose diameter is between 1.75 and 1.80 mm, the diameter of the groove is at least 2 mm.
  • the metal bridges separating two housings 3a before the digging of the grooves 8 are thicker.
  • the distance between centers of two neighboring bores is 1.97 mm.
  • this distance is less than the external diameter of the grooves 8 so that the grooves of two neighboring housings overlap as shown in FIGS. 6 and 7.
  • the marks 8a represent the intersections of the groove 8 of the bore located in the plane cutting with the grooves in the bores located behind the cutting plane.
  • grooves overlap means that the cross sections of the feet of the claws are small enough to flex laterally to allow the stones to pass and then to buckle during crimping.
  • the machining of the grooves 8 is carried out on a numerically controlled machine tool by means of a rotary cutter which is positioned successively in the axis of each of the bores 3.
  • Figures 8 and 9 show another step in the machining of a support 1 in the second embodiment.
  • a rotary cutter 9 is mounted on the tool holder which comprises a milling head 9a having an internal edge 9b of rounded shape, for example in quadrant shape.
  • the height of the milling head is preferably equal to or slightly greater than the distance separating the median plane of the groove 8 passing through the bottom of said groove from the external face of the support, so that the cutter 9 removes metal only above the back of the throat.
  • the support 1 By moving the work table, the support 1 is placed in successive positions where the x xl axis of the tool passes through the points 0 located at the center of each triangle formed by the centers 0 1 , 0 2 and 0 3 of each group of three bores 3 arranged in a triangle.
  • Each metal island which constitutes a claw comprises a hemispherical head 10a, 10b, 10c, which has been cut by the rounded edge 9b.
  • This edge surmounts a foot of smaller section which has the shape of a curvilinear triangle whose three sides are concave and are delimited by three sections of circular groove 14a, 14b, 14c, of triangular section which penetrates under the hemispherical head.
  • the circle inscribed inside the six claw heads which is the primitive circle 3a, has a diameter less than the outside diameter of the stone.
  • a stone 2 is engaged in each housing 3 surrounded by six claws. When the stone is engaged, it repels the claws 10a, 10b, 10c, etc. towards the outside of the housing 3.
  • the claws deform by flexion of the foot which is weaker and this deformation is a permanent deformation.
  • each claw 10a, 10b, 10c is then pressed axially ... the hollow end Ila of a crimping tool 11.
  • This end 11a preferably has a hemispherical shape which matches that of the heads.
  • the thrust of the tool 11 causes the axial buckling of the foot of each claw.
  • the grooves 14a, 14b, 14c which delimit a foot of reduced section, facilitate, on the one hand, the bending of the claws towards the outside when a stone is engaged and, on the other hand, the buckling of the foot.
  • each claw is held laterally by the three stones which surround it, so that they cannot flex laterally and an axial buckling is obtained.
  • the crimping process by axial buckling is different from the crimping methods in which the claws are folded over the stones as well as by snap methods in which the stones are pressed between claws which elastically deform and then return to their initial position under the action of elastic return forces.
  • FIGS. 10 and 11 represent a second variant of the embodiment according to FIGS. 6 to 9.
  • the first stages of machining are identical to those of the previous process, that is to say that, in a first stage, rows of cylindrical-conical housings 3 are hollowed out, staggered as shown in the figures 2 and 3, then a groove 8 having a triangular profile is cut at the periphery of these housings as shown in FIGS. 6 and 7.
  • FIG. 10 represents a partial plan view and FIG. 11 a section along XI-XI during the machining operation of the metal bridges which separate the bores 3.
  • This machining is carried out by means of a rotary milling cutter 12, d axis x xl, which comprises a milling head 12a having an internal edge 12b, of concave shape
  • the radius of the tool 12 is greater than the radius of the tool 9.
  • each island is delimited by three grooves 14 which are sections of three grooves 8 arranged in a curvilinear triangle, which penetrate under the dome.
  • FIGS. 10 and 11 show an island 13 which has been hatched for clarity of the drawing.
  • a stone is then inserted into each housing 3 by pressing it on the seat 3b, then a crimping tool having a hollow head into which the island penetrates is applied to each island 13 and it is pressed enough to achieve deformation permanent by buckling of the feet of the islands delimited by the grooves 14.
  • each stone is set by six claws 13, of curvilinear triangular shape with convex faces which give the jewelry an original aesthetic appearance.
  • Each claw 13 is common to three stones and located in the center of these.
