Definitions

• a method for providing a decoration in an electroplated watchmaking member and a housing element made therein is a method for providing a decoration in an electroplated watchmaking member and a housing element made therein.
• the present invention relates to a method for manufacturing a watchmaking clothing element in which is implanted at least one decoration.
• Patent application EP 2192454 A1 discloses a decoration deposited by electroplating on a cladding element by means of a mask which is filled with a metallic material.
• This decoration may also include anchoring means ensuring its good resistance in the element in question, these anchoring means being also deposited by electroplating.
• anchoring means being also deposited by electroplating.
• it is the covering element which is created by electroplating and not the decor as proposed in the patent application cited above.
• the maintenance of a gemstone on a support is also provided by a deposit made by electrodeposition in US 6212745B1.
• the present method in addition to being in accordance with the wording of the first paragraph of this description, is noteworthy in that it comprises the following succession of steps: a decor made of parts anterior and posterior respectively intended to emerge from the cladding element and serve as anchoring means of said decoration in said cladding element; providing a master executed to the dimensions of the cladding element, this master having a hollow footprint and adapted to the dimensions of the front part of the decoration; placement of the decoration in the master, the anterior part of the decoration filling the imprint practiced in the master; filling of the master by galvanic deposition of a metal to obtain the desired dressing element, and removal of the master of the cladding element obtained.
• the present invention also relates to the watchmaking element executed according to the method above.
• FIG. 1 is a view from above of an example of a master used to produce a watchmaking element, here a watch face,
• FIG. 2 is a section along the line 11-11 of FIG. 1;
• FIG. 3 shows in section a decor to be implanted in the master of FIGS. 1 and 2, here an index indicating the time
• FIG. 4 shows the operation of depositing the decoration in the master of FIGS. 1 and 2,
• FIG. 5 shows the beginning of the filling of the master by the metal deposited by electroplating
• FIG. 7 shows the final clockwork element obtained by demolding the master
• Figure 8 shows a variant of decor after filling the master.
• Figure 3 is a section in a decor 1 to be implanted in a watchmaking element 4 (Figure 7), for example an hour indicator index on a dial.
• This decoration 1 comprises an anterior part 2 which will emerge from the covering element and a rear part 3 which will serve as anchoring in said element.
• Figures 1 and 2 are respectively a top view and a section in a master 5 executed to the dimensions of the dressing element to produce.
• This master 5 has a hollow footprint 6 adapted to the dimensions of the anterior portion 2 of the decor 1. In the case of a watch dial, the master 5 will present twelve prints 6 to receive twelve hour indicator indexes.
• FIG. 4 shows the operation of laying the decor 1 in the master 5, the anterior part 2 of the decor 1 filling the imprint 6 practiced in the master 5.
• the decor 1 being put in place, one can begin to complete the master 5, which is clearly shown in FIG. 5.
• This filling is done by galvanic deposition of a metal 7, for example gold, copper, nickel, platinum, silver palladium or any metal or metal alloy. electrodepositable of interest for the watchmaking domain. It is stopped when it has passed the end of the posterior part 3 of the decoration 1, as represented in FIG.
• FIG. 7 shows the clockwork element 4 completed when it has been extracted, by demoulding, from the master 5. After demoulding, its rear face 8 can be leveled if necessary.
• the master 5 is metal, it is necessary to treat its surface with a chemical passivation coating it with a thin oxide layer before proceeding with the galvanic deposition of the covering element. This layer is sized to attract the electrodeposited metal without it permanently adheres to the master 5, thus separating the master of the cladding element.
• the master 5 is non electrically conductive material, for example plastic or a ceramic, it is then necessary to coat its surface with a metallization to make it conductive and thus attract the electrodeposited metal. For this purpose it is possible to deposit, for example by PVD, a thin layer of chromium (50 nm) and gold (50 nm) on which the galvanic deposition can adhere at the same time as it will allow the demolding of the element. dressing.
• the decoration is made of metal, there will be total adhesion of the covering element with the posterior part 3 of the decoration 1. If the decoration is non-conductive material, there will be overlap of the electrolytic deposit first on the body 10 shown in Figure 5 and which will be discussed below, then on the top of the rear portion 3 of the decor 1 to finally enclose completely said decor 1 as shown in Figure 6.
• FIG. 8 shows that a rear portion 9 of the front portion 2 of the decoration 1 is taken from the metal 7 of the covering element 4.
• This way of producing the decoration different from that shown so far, where the decoration physically emerges from the finished trim member allows, if one grinds the front portion 2 of the decor 1 to the line 1 1, to bring this decoration at the level of the trim element after demolding of this latest.
• the decoration 1 is then flush with the cladding element and is distinguished from it by a different color, for example steel for decor and galvanic gold for the cladding element 4.
• the figures in which the decoration 1 is shown show that the posterior part 3 of the decoration 1 is provided with a draft 1 0. It will be understood that the latter ensures an unstoppable mechanical retention of the decoration 1 in the covering element 4.
• the clockwork element 4 mentioned above may be a watch face as has already been said. It could also be a bezel with hour markers, a caseband or a bracelet buckle bearing a mark.
