Description

The present invention relates to a decorative piece. This decorative piece comprises a support in which at least one aesthetic element is crimped.

BACKGROUND TECHNOLOGY

It is known in the prior art decorative parts to be reported on a portable object such as a watch or a jewel and consisting of crimping aesthetic element on the parts of said portable object acting as a support.

For this, the support is made of metal alloy and is machined for housing appear. During this machining, hooking means in the form of hooks are made. Generally, these hooks are made with the material forming the portable object that is to say one-piece with the object. When an aesthetic element, such as a gemstone, is to be crimped, the latter is placed in a housing and the hooking means are folded cold by plastic deformation so as to maintain said aesthetic element in the housing. This method of crimping is widely used to crimp precious stones on metal supports because the latter has an advantageous plastic deformation capacity. This ability is even more advantageous with precious metals such as gold because these precious metals are ductile and can be easily shaped. The cold plastic deformation of the crystalline metals is possible thanks to the movements of the dislocations present in the crystalline lattices. The elastic limit, that is to say the stress beyond which a material begins to deform plastically, of a crystalline alloy depends on the elements composing the latter as well as on the thermomechanical history of the alloy. . For traditional crimping, alloys having relatively low elastic limits are generally chosen to facilitate the work of the crimper. In addition to a relatively low elastic limit, it is necessary that the alloy has sufficient elongation before rupture to be able to fold the hook means without breaking. As for the elastic limit, this elongation is the consequence of both the elements present in the alloy and the thermomechanical history of the latter. For example, the gold alloys used in watchmaking have an elastic limit of the order of 200-400 MPa and an elongation at break of 20-40%. Type 1.4435 stainless steels have a yield strength of 200-300 MPa and an elongation at break of 25-45%.

However, a disadvantage of this method is that it is confined to the supports made of ductile metals or metal alloys. However, more and more timepieces are made in materials that do not exhibit plastic deformation, often hard and / or fragile, such as for example ceramic, silicon, composites or intermetallic alloys.

Therefore, it is no longer possible to use the current method to crimp aesthetic elements such as precious stones.

This crimping operation is replaced by a bonding operation. Bonding has the disadvantage of not ensuring a 100% stone resistance because unlike crimping, this technique does not involve mechanical retention of stones. Indeed, the glued areas being in most cases exposed to the external environment (moisture, sweat, UV, air pollution, ...), the holding of the bonding in the long term is made difficult. Therefore, the holding of the stones is not assured which is not acceptable for quality products.

DETAILED DESCRIPTION

In the following description, all parts of the decorative part which are well known to those skilled in this technical field will be explained in a simplified manner.

As visible in FIGS. 1 and 2, the present invention is a decorative piece 1. It consists of a first part 2 and a second part 3. The two parts 2, 3 are arranged to become integral with each other. More particularly, the second part 3 is intended to be crimped in the first part 2. For example, the first part may be a support 2 and the second part 3, one or more aesthetic elements. This or these aesthetic elements 3 can be precious stones such as diamonds or rubies or non precious like zircons or any other possible aesthetic element.

In FIGS. 1 and 2 show examples of embodiments of the invention. The decorative piece 1 may be, for example, a watch bezel 10 inlaid with indicia as shown in FIG. 1 or a watch glass 11 visible in FIG. 2 or a dial 22 or any external parts of a watch or timepiece. In the example of a dial, the latter comprises a discoidal body forming the support 2 in which are crimped aesthetic elements 3. This dial can be, for example, made of ceramic. It will be understood that ceramics are not the only material that can be used. Thus, any material that does not exhibit sufficient plastic deformation can be used such as sapphire, silicon or glass. In the case of a sapphire crystal, the interest is to crimp the said ice allowing a visual effect in three dimensions such as a time lapse or a logo above the needles. It will be understood that the decorative piece 1 can also be a pen or a cufflink or a jewelery item such as a ring or an earring. The surface of the support 2 which will be crimped may be flat or curved, that is to say concave or convex.

Advantageously according to the invention, this support 2 comprises at least one recess 4, shown in FIG. 4, arranged on said support to allow the crimping of at least one aesthetic element. Each recess 4 is then in the form of a pattern and has flanks 7, preferably substantially perpendicular to the visible surface. These recesses 4 are used to allow the use of a substrate 6 for crimping. Indeed, the invention proposes to fill said hollow 4 with a first material more easily deformable so as to crimp said at least one aesthetic element 3, which is not possible with a support 2 of ceramic or silicon. Thus to fill said recesses 4, it is envisaged to use in the present invention a first metal material.

The first step, visible in FIG. 3, is to provide the support 2 in a material that does not deform plastically.

The second step, visible in FIG. 4, therefore consists in producing at least one recess 4 in the support 2. This recess 4 can be made for example by machining, by laser ablation, see directly during the molding of the support or by any other technique.

The third step is to fill said recess with a first material. This first material is then used to serve as substrate 6. The third step makes it possible to obtain the support 2 visible in FIG. 6.

Advantageously according to the invention, the first material is an amorphous metal alloy. It will also be understood that the metallic material will be partially amorphous or totally amorphous. The partially amorphous term indicates that for a block of material, the percentage of material amount of said block having the amorphous state is sufficient for the block itself to have the characteristics specific to amorphous metals and metal alloys. The amorphous materials have the advantage of being easily shaped. Similarly, it may be possible to use a precious metal or one of these alloys to give a noble character to said decorative piece. Thus, the precious metal or one of these alloys is included in the list comprising gold, platinum, palladium, rhenium, ruthenium, rhodium, silver, iridium or osmium.

One of the methods for filling the hollow is to use hot forming. Figs. 5 and 6 show in a simplified manner the steps of filling the hollow 4. In the first place, it is firstly necessary to make the support 2 as visible in FIG. 3 and, on the other hand, to produce a preform 6a amorphous metal alloy. This preform 6a may be made by various techniques such as, for example, injection into a form mold, hot forming above Tg, stamping of the strip, or by machining. Once this preform 6a has been made, it is placed above the support 2, as shown in FIG. 5, on the face where said hollow opens 4 to perform the filling of said recesses by hot forming. The assembly is then heated to a temperature above the glass transition temperature Tg, thus allowing a decrease in the viscosity of the preform, and then a pressure is exerted. Once these conditions are met, the pressure exerted on the viscous preform allows the viscous amorphous metal alloy to fill the recess 4 as shown in FIG. 6. Then, when the recesses 4 are filled as shown in FIG. 6, the assembly is cooled in order to maintain the amorphous state of the alloy.

This type of material is well suited to the fact that they can easily fill the entire volume of the hollow 4. After cooling, the vertical flanks 7 can retain the amorphous material by friction. Of course, the flanks 7 may be inclined to shrink the surface of the horizontal plane at the bottom of the recess 4 or on the contrary so as to enlarge. It goes without saying that the most advantageous case is that where the surface of the bottom of the hollow 4 is the largest since it allows to naturally retain the amorphous metal alloy in the recess 4. Conversely, when the inclination generates a larger section at the surface of the support 2, maintaining the amorphous material in the recess 4 is no longer optimal. Another advantage is that this decreasing viscosity causes a decrease in the stress to be applied to fill the recesses 4 with the amorphous metal alloy. Therefore, the support 2 of fragile materials is not likely to break although a pressing operation is performed.

Of course, other types of formatting are possible such as shaping by casting or injection, by densification of powder or by hunting.

The casting or injection process consists of heating a metal preform above its melting point and then pouring or injecting the liquid metal thus obtained into the recess 4 of the support 2.

The powder densification process consists in introducing a metal powder into the recess 4 of the support 2 and consolidating it by a supply of energy such as an oven, a laser beam, an ion beam or any other thermal means. Once the hollow 4 filled, a cooling step to a temperature below Tg is performed to prevent the crystallization of the alloy to obtain a hollow 4 filled with amorphous or semi-amorphous metal alloy.

The hunting process consists in producing an amorphous metal alloy block whose dimensions and shape are slightly larger than those of the recess 4 and forcing the block to enter said recess 4. Advantageously, it can be planned to perform this assembly step using thermal expansion. To do this, the support 2 is heated so that, under the effect of heat, it is thermally expanded. The support 2 sees its dimensions increased. This increase in dimensions is also applicable to the recess 4. Consequently, the difference between the dimensions of the recess 4 and the dimensions of the block is modified so that the dimensions of the recess 4 become larger than those of the block. It is then easy to insert the block in the hollow 4. When the support 2 is cooled, it resumes its initial dimensions and the block is stuck in said recess 4.

Once the hollow filled, a fourth preparation step is performed. This step consists in manufacturing the crimping housings (holes) in which the aesthetic elements 3 are placed, and in manufacturing the hooking means. This step can be carried out either conventionally such as machining, milling, drilling, or in a less conventional manner, by hot deformation, or by a combination of both ways. The method of hot deformation comprises using a tool having the negative geometry of the hole and the crimping element and applying this tool, with a certain force and at a temperature higher than the glass transition temperature Tg of the amorphous metal, on the amorphous metal alloy filling the hollow 4. It is thus possible to avoid the machining steps that can be difficult depending on the amorphous metal alloys used.

The hooking means 5 is in the form of at least one crimping element 9. This crimping element 9, in the case for example of a crimping grains, consists of pads or grains arranged on the around each crimping hole 8. These studs 9, visible in FIGS. 8 and 10, are produced by machining and are produced before or after the drilling of the crimping holes 8. In fact, during the machining of the holes, the material of the substrate 6, that is to say of the first material, is removed in order to form these crimping grains 9. Preferably, in the case of grain crimping, it is expected to ideally have four crimping grains 9 near each crimping hole 8 as shown in FIG. 10.

It will be understood that other types of crimping can be envisaged. Therefore, closed crimping, crimping stick, crimping rail or invisible crimping are possible. For example, the closed crimping consists of a single crimping element 9 extending on the periphery of the aesthetic element 3. The crimping rod is used to crimp the aesthetic elements 3 cut into rods. This crimping consists in providing crimping elements 9 extending parallel to each side of the aesthetic element 3 coming down on the latter. For invisible crimping, it is provided that the crimping elements 9 are projecting portions arranged in the crimping hole 8. These projecting portions cooperate with at least one groove made on said aesthetic element 3 so that the crimping is done by inserting the aesthetic element 3 in the hole 8 until the projecting portions fit into said at least one groove.

In a particular embodiment shown in FIG. 10, the aesthetic element 3 is in the form of a diamond comprising a yoke 3b in which are cut several facets and a crown 3c also faceted surmounted by a 3d table as shown in FIG. 15. This aesthetic element has, seen from above, a substantially circular shape. For the illusion of crimping in the material of the support 2 is intact, it is expected that the width of the recess 4 is ideally equal to that of the aesthetic element 3. Preferably, it will be understood that the distance between the aesthetic element 3 and the edge of the recess 4 must be at least 0.01 mm so that the visual effect of the aesthetic element 3 in the support 2 is optimal, that is to say to have the impression that the aesthetic element 3 remains embedded in the ceramic support 2 and not in a metal. For the maximum distance between the aesthetic element 3 and the edge of the recess 4, this will depend on the dimensions and shapes of the aesthetic elements 3. For example, for an aesthetic element 3 with a diameter of 1 mm, the distance between the aesthetic element 3 and the edge of the recess 4 will be 0.45 mm.

In another example, it is defined that the distance between the aesthetic element 3 and the edge of the recess 4 consists of a so-called worked zone, that is to say an area in which the crimping grains are made, this area can be hollow, and a so-called non-worked area which is an aesthetic and visual area. In this case, this non-worked area will be at least 0.01 mm and at most 0.20 mm. Preferably, it will be 0.10 mm.

Similarly, it will be understood that the height of the hole 8 is at least equal to the height of the cylinder head of the aesthetic element 3. This allows, when the aesthetic element 3 is crimped, to see as little as possible the first constituent material of the substrate 6. In this case, the crimping grains 9, four in number, are made so as to have a shape of a right triangle whose hypotenuse is convex. Preferably, the convex shape of the hypotenuse is similar to the curvature to that of the aesthetic element 3 when it is seen from above.

Once the fourth stage of preparation is complete, we obtain the support 2 visible in FIG. 7, the fifth crimping step can then take place.

The conventional crimping step consists of a deformation. This technique consists of placing the aesthetic element 3 in the hole 8 and deforming the substrate and / or the crimping elements 5 to press them on said aesthetic element 3 as shown in FIGS. 9 to 13. As a result, the latter is held in the crimping hole 8. The deformation can be plastic. In this case, it is done with a tool called perlayer 100 used to deform each crimping element 9, it allows to obtain the aesthetic element 3 set in FIG. 13.

The deformation may also be elastic or obtained by thermal expansion. In the case of elastic deformation, the crimping is obtained by clipping the aesthetic element in the hooking means 5. It is obvious that in this case, a slight plastic deformation hooking means 5 could take place. In the case of deformation by thermal expansion, the crimping is obtained by heating the support 2 to a sufficiently high temperature to allow the encrustation of the aesthetic element 3 in its hole 8 without effort. The cooling will then make it possible to contract the material thus making it possible to maintain the aesthetic element 3 by the hanging means 5.

It should be noted that amorphous metals, unlike crystalline metals have no dislocations and therefore can not plastically deform by the movement of the latter. They therefore generally have a fragile behavior, that is to say that they suddenly break once the elastic limit exceeded. It has been found, however, that some amorphous alloys can accommodate macroscopic permanent deformation by generation of slip bands at the microscopic scale. The exact nature of these is not yet clearly identified. In addition to being dependent on the type of amorphous alloy, the ability to accommodate permanent deformation in amorphous metals is highly dependent on the dimensions of the part. Thus, the smaller the dimensions of the area requested, the greater the permanent deformation. For example, it is possible to permanently bend a strip of thickness 100 | im amorphous Pt57.5Cu14.7Ni5.3P22.5 alloy to an angle greater than 90 ° without rupture, while a strip of the same amorphous Fe56Co7Ni7Zr8Ta8B20 alloy dimension will not accommodate any permanent deformation.

In view of the foregoing and to be able to use different amorphous alloys regardless of their permanent deformation capacity, different embodiments have been devised. !

A first embodiment is used in the case where the amorphous alloys accommodate permanent deformation and having not too high elastic limits, typically less than 1500 MPa: The crimping method is identical to that used for crystalline metals, that is to say the cold plastic deformation of the grains 9 created in the amorphous alloy.

A second embodiment is used in the case where the amorphous alloys having elastic limits too high for cold plastic deformation, typically greater than 1500 MPa: The crimping method consists in heating the grains 9 to a higher temperature at the glass transition temperature Tg of the amorphous metal alloy in order to greatly reduce the viscosity and therefore the force required for their deformation. Once the grains 9 at the right temperature, they are deformed so that crimping can take place. A cooling operation is then carried out to solidify them and make the crimping permanent. This solution has the advantage of allowing intimate contact between the amorphous metal alloy and the aesthetic element 3, which improves the resistance of the latter. Indeed, in the case of cold plastic deformation, for both crystalline and amorphous metals, a springback occurs during the relaxation of the force applied to the grain 9. This return inevitably implies a slight separation between the grain 9 and the aesthetic element 3, which can cause problems of holding. However, the hot deformation used does not involve elastic return and release is not therefore performed. This hot deformation can be performed after a cold deformation step or vice versa.

A third embodiment is used when the amorphous alloys are difficult to crimp by cold or hot plastic deformation. This mode consists of taking advantage of the large elastic deformation of amorphous alloys, typically 2%, unlike crystalline alloys which deform plastically from 0.5%. The method consists in pressing the aesthetic element 3 into the crimping hole 8 of the substrate 6. Under the pressure, the amorphous metal alloy of the substrate 6 is deformed elastically allowing the aesthetic element 3 to be inserted. When the hooking means 5, in the form of a crimping recess, and the rondiste or the end or the edge 3a of the aesthetic elements 3 are opposite one another, a springback takes place. The elastic return of the hooking means 5 on the aesthetic element 3 makes it possible to definitively maintain the latter as visible in FIGS. 15 and 16.

A fourth embodiment is also envisaged. In this mode, the support 2 is heated thermally so that all the support expands, that is to say the support 2 and the substrate 6 amorphous alloy. As a result, the crimping hole 8 also expands. Therefore, the aesthetic element 3 can be placed in the crimping hole 8. The aesthetic element 3 is then held in the hole 8 by the hooking means 5 after cooling the support 2 as visible in FIGS. 17 and 18. These hooking means 5 is in the form of a crimping recess in which the rondiste or the end or the edge 3a of the aesthetic element 3 is inserted.

A fifth embodiment can be envisaged in which the fourth step d) and the fifth step e) are simultaneous. This mode consists of heating the aesthetic element to a temperature above the glass transition temperature Tg of the first material and then pressing it therein, that is to say the amorphous metal alloy. The heat released by said aesthetic element locally heats the substrate 6 to a temperature greater than Tg which allows the amorphous metal alloy to greatly reduce its viscosity thus facilitating insertion. Once the aesthetic element has been inserted, the Substrate 6 is cooled to maintain the amorphous state of the alloy and is deburred from any surplus material. This step thus allows a better grip of the aesthetic element 3 in the substrate 6 due to the ability of the amorphous metal alloy to marry the contours. 1

A sixth embodiment in which the third c), fourth d) and fifth step e) are simultaneous, is envisaged. This variant consists in providing that the aesthetic element 3 is directly placed in the recess 4 before the step of filling said recess 4 with the first material. The filling of the recess 4 is then by casting, by hot forming or by densification whose details have been explained previously. This technique makes it possible to have a faster crimping process while ensuring a good maintenance of the aesthetic elements 3.

A seventh embodiment, characteristic of an invisible crimping, visible in FIGS. 19 to 23 can be done. In the latter, the support 2 is provided in its bottom with a hole 30 for filling. Indeed, the method consists in providing a base 200 on which the aesthetic element or elements are placed. These are placed upside down. For example, for an aesthetic element such as a precious stone carved to include a breech in which are carved several facets and a crown also faceted surmounted by a table, the table is in contact with the base and the breech point towards the top. Then, the support 2 is placed so that the recess 4 is facing the base and so that the aesthetic element or elements 3 are located in the space formed by the recess 4. Preferably, the aesthetic elements 3 are located to each other according to their definitive arrangement. Of course, other stone devices may be envisaged, for example stones with all the stones' heads pointing downwards, or stones randomly arranged such that some stones have the yokes up, others have the breeches down. Then, the first material, i.e., the amorphous metal alloy that is stored in apparatus 300, is poured or infiltrated into the recess through the hole 30 for filling. The first material is thus preferably cast, injected or thermally pressed into said hollow 4 and then solidified to freeze the position of the aesthetic elements 3. Advantageously, the hole 30 for filling is also filled so that, according to its profile, it can serve maintaining the first material in the recess 4. Finally, the base 200 and the support 2 are separated to obtain the decorative part 1 according to the invention. Of course, it will be understood that the aesthetic elements 3 can be put edge to edge to prevent the amorphous metal alloy is visible. In the case of aesthetic elements 3 cut to include a cylinder head 3b in which are cut several facets and a crown 3c also faceted surmounted by a table 3d, the fact of putting the aesthetic elements 3 edge to edge allows the metal alloy amorphous does not seep between the crowns.

In a variant of the fifth to seventh embodiments, the aesthetic element 3 comprises at least one groove 31. This groove 31 allows, during crimping of the aesthetic element, the amorphous metal alloy is inserted in said throat 31. Indeed, as the amorphous metal alloy perfectly matches the contours of a room when heated to a temperature above Tg or when it is liquid, the groove 31 then serves as a means for anchoring the aesthetic element in the amorphous metal substrate 6 as shown in FIG. 23.

An advantage of the invention is that it can crimp any type of material. Indeed, the principle used is an insert principle that is to say that a substrate material capable of accepting a deformation is reported in a material that is not plastically deformable so as to allow crimping and to give the illusion that it is this non-plastically deformable material that is crimped.

In a first variant visible in FIG. 14, the maintenance of the first material is improved by using holding means 50. These holding means 50 comprise at least one recess 51 and / or at least one protrusion 52. These holding means 50 are made prior to the filling of the Thus, during the filling of said hollow, the first material fills the recesses 5a or the protuberances 5b become trapped in said first material, and as a result, when the first material fills the recess 4 and is solidified, it is perfectly maintained in said recess 4.

In the case where the first material is an amorphous metal alloy, the low viscosity of the amorphous material makes it possible to fill the recess 4. By analogy, this low viscosity of the amorphous material also makes it possible to better fill the recesses 51 or better. wrap the growths 52.

These recesses 51 or protuberances 52 may be located on the vertical flanks 7 of the recess 4 or at the bottom 7a of the recess 4. Similarly, the recesses 51 may be through or not.

It will be understood that various modifications and / or improvements and / or combinations obvious to those skilled in the art can be made to the various embodiments of the invention described above without departing from the scope of the invention defined by the appended claims.

Thus, it is conceivable that once the amorphous metal is shaped in the recess 4, a crystallization step takes place just before or just after the step of making the crimping holes 8. This step consists of heating the amorphous metal above its glass transition temperature Tg for a time long enough for crystallization to take place. Once crystallized the alloy can be cooled. The crystallization parameters (time and temperature) must be chosen so as to ensure the crystalline phase (s) crystalline (s) ductile (s) and not brittle (s). This makes it possible to take advantage of the shaping properties of the amorphous metal and to take advantage of the facility of the crystalline metals to deform plastically, especially when cold.
