[Figure 6] This is a view similar to Figure 5, according to an embodiment of the present invention, showing a blank with a pattern on a three-dimensional surface coating. [Modes for carrying out the invention]

[0013] Referring to Figures 1-6, the present invention relates to a method for manufacturing the dial 2 of a clock 1. The eel clock 1, in particular, has a case 16 that houses the movement, and this dial 2 and hands 15 This is a wristwatch that includes a display device. This wristwatch 1 is worn on the wrist of the wearer of this watch 1. To be dressed.

[0014] The case 16 of this watch 1 further includes a central section 9 to which the bracelet 10 is attached. In this watch 1, such a dial 2 is placed inside the case 16, and has a small surface area, visible Includes surface 11. Such a surface has very small dimensions. This small surface area is preferred. Or, 700mm 2 From 1700mm 2 This is between. This surface is the case 16 of watch 1. This is limited by the following: In other words, this surface is limited by the dial 2, or the visible surface 11. Since it is surrounded by the inner circumferential wall of the enclosure 16, it is restricted by this case 16. It can be said that the dial 2 of the present invention is the dial of a clock, that is, the operation of this clock An object intended to be carried / worn by an individual while traveling, without modification; in this case, a watch. It is understood that it is configured to be installed in [a certain device].

[0015] This dial 2 is a three-dimensional representation 3, more precisely a tertiary representation including a topographic map related to the landscape. It is characterized by having a visible surface 11 with original decoration. In other words, this three-dimensional representation Number 3 is a topographic map of the landscape.

[0016] Such landscapes are preferably actual or existing landscapes that exist in nature. A landscape is composed of all the elements that can be observed from a particular location. In other words, It is the visible appearance of geographical space. Such landscapes are non-limited and non-exclusive. These landscapes can be terrestrial, such as mountain ranges, or underwater, such as ocean trenches. This may include, but is not limited to, features such as undulations, cavities, water, and / or vegetation.

[0017] As already mentioned, this three-dimensional representation of the landscape 3 is generated on the visible surface 11 of this dial 2. This visible surface 11 is when the dial 2 is mounted on the case 16 of the watch 1. On the surface of the dial 2, which is observable / visible to the user wearing such a watch 1 handle.

[0018] The three-dimensional representation 3 of this landscape generated on / within this visible surface 11 is in the form of a topographic map. This dial 2 is faithful to the actual or existing landscape that it attempts to reproduce. In short, The reproduction of this existing landscape on dial 2 corresponds to or describes this landscape. It is based on shape data. Such data is called "topographic landscape data" or "raw topographic data." This may be called "data". Such data includes measurements from topographic surveys. These were collected directly on the ground in relation to this landscape, specifically for the purpose of transferring them onto this dial 2. These measurements, though not limited to them, involve two components, namely water. Plane survey components and horizontal references measured during plane surveying to determine the position of a point in a plane. This includes an altitude measurement component measured during altitude measurement, which gives the position of the same point on or below the surface.

[0019] This three-dimensional representation 3 is generated over substantially the entire visible surface 11 of the dial 2. Please note the following. More specifically, this expression 3 is 80 of this surface of the visible surface 11. It is generated over % or 90% of the visible surface 11, or over the entire surface. In other words, This three-dimensional representation 3 occupies between 15% and 100% of the visible surface 11 of this dial 2. .

[0020] Recreating landscapes on dial 2 in this way respects these topographic data accurately, 1. The dial 2. A faithful and accurate representation of the landscape scaled to the dimensions 3. Reversible It can be said that this is accurate. In other words, the actual composition of the landscape elements reproduced on this dial 2 The dimensions can be obtained from measurements taken directly from this three-dimensional representation 3, and the actual dimensions of this landscape This landscape can be reproduced on a different scale while remaining true to its original dimensions.

[0021] In this embodiment, the manufacturing method is to first manufacture the blank 12 for the dial 2 of the clock 1. Including step 20, this blank 12 is a three-dimensional structure 5 related to the three-dimensional representation 3 of the landscape. Includes.

[0022] In this blank 12, the upper surface 13 is the visible surface 11 of the dial 2 to be manufactured. handle.

[0023] Such a step 20 is a substep that provides the substrate constituting this blank 12. Including 21. This substrate is preferably to have the final shape and dimensions of the dial 2 to be manufactured. These substrates are made from rigid materials. These materials include metallic materials and metallic alloys. The substrate may be a material and / or an industrial ceramic type material. This substrate may be, for example, a copper alloy. Gold, stainless steel, precious metals, titanium, alumina, doped or undoped Strontium luminate, stabilized or unstabilized zirconia, hybrid Organic-inorganic materials, or any metal alloy that may be used in the field of watchmaking, industrial It can be made from ceramics or any composite material. The term refers to aluminum oxide and / or zirconium oxide and / or stabilized zirconium oxide. nium and / or nitrides and / or carbides and / or strontium aluminate, especially This is understood to mean a high-density material based on compressed strontium aluminate. The term "high density" refers to a density between 95% and 100% of the theoretical density of the material in question. It is understood to mean the material. The expression "based on a specified compound" means that the material is the aforementioned This means that it contains at least 50% of the compound's weight.

[0024] This manufacturing step 20 is a base for constructing a three-dimensional structure 5 on the top surface 13 of the blank 12. This also includes substep 22 for generating shape data. Referring to Figure 4, this three-dimensional structure 5 is At least one flat zone 6a and / or at least one including 1 relief Two raised zones 6b and / or at least one recessed zone including at least one recess It contains n6c, and this recess can also be called a rib.

[0025] These zones 6a, 6b, and 6c are defined with respect to the reference plane of the blank 12. Please note: This reference plane is small and flat, and is modified to generate the three-dimensional structure 5. It is included in the top surface 13 of the blank when not being included. This reference plane is shown in Figure 4. It lies within plane P. In this configuration, the flat zone 6a is included in the reference plane, and therefore flat It is located within surface P, with a raised zone 6b above the reference plane and a recessed zone 6c below this plane. .

[0026] Such substep 22 uses these terrain data to construct the three-dimensional structure 5. This is carried out by a system for generation. This system is non-exclusive and non-limiting. , controller and communication module, and terrain landscape data, also known as raw terrain data. It includes a database containing this information.

[0027] In this system, the controller, also called the processing unit, uses hardware resources. Electronic circuits including, in particular, memory elements and a small number of components that cooperate with address, data and control buses. It includes at least one processor. This controller has a three-dimensional structure within its memory element. Includes an algorithm for generating terrain data to construct 5. This includes the surface area of ​​the upper surface 13 of the blank 12, the basic shape of this surface 13, the dimensions of this surface 13, and / or, taking into account the calculation criteria such as the properties of the material of the substrate constituting this blank 12, These are executed by the controller's processor. These criteria are perceived by the observer. This further includes the visual characteristics of the three-dimensional structure of the upper surface 13 that constitutes the three-dimensional representation 3 of this landscape. That's fine. Such algorithms, when applied to raw terrain data, can help determine wind. The three-dimensional representation of the scenery 3 is based on predetermined dimensions, namely the dimensions of the blank 12, and in particular the dimensions of its top surface 13. It should be noted that this particularly contributes to scaling.

[0028] This controller connects to the database via a communication module. Therefore, the communication module connected to the controller has the ability to connect it to the database. It includes wired or wireless connection elements.

[0029] In this context, the generation substep 22 generates a three-dimensional structure 5 on the upper surface 13 of the blank 12. Phase 23 includes capturing raw terrain data about the landscape used to generate the results. Hmm. Therefore, during this phase 23, the controller places a pattern on this blank 12. Establish a connection to a database containing such topographic data related to the landscape being landscaped. This process incorporates the raw topographic data.

[0030] Next, this substep 22 is to process the raw terrain data associated with this landscape. Therefore, it includes a phase 24 for acquiring terrain configuration data, and this processing operation is controlled by the controller. This is executed by the algorithm that is executed. More specifically, this Phase 24 In between, the controller, by executing this algorithm in this way, The calculation is performed on the terrain data. The purpose of such calculations is, in particular, blank 12 The surface area of ​​the top surface 13, the basic shape of this surface, and the material of the substrate that makes up this blank 12. The properties, and the three-dimensional structure 5 of the upper surface 13 that constitutes the three-dimensional representation 3 of this landscape, by the observer The goal is to acquire terrain composition data while considering the recognized visual features. The resulting visual features improve the visual rendering of this structure 5 on the generated upper surface 13. This is useful. These features are, for example, in the different zones 6a, 6b, 6c of this structure 5. In other words, the dimensions of the flat zone 6a, the raised zone 6b, and / or the recessed zone 6c are changed. Therefore, by correcting the values ​​of the raw terrain data, we can observe this three-dimensional structure 5. It relates to the enhancement or improvement of contrast as perceived by the user. For example, this algorithm The rhythm is located around zone 6a~, which is situated around at least one modified zone 6b, 6c. For the average of 6c, at least one recessed zone 6c and / or at least one raised zone By balancing and modifying zone 6b, at least one flat zone of structure 5 The contrast of 6a can be increased. In this context, the at least one of the above The modified zones 6b, 6c, i.e., in this case, the at least one recessed zone 6c and the at least one of the raised zones are modified in depth and height / elevation, respectively. .

[0031] Each of these terrain configuration data sets has three axes: horizontal (X and Y) and vertical (Z). This includes spatial measurement information along the perpendicular axes X, Y, and Z. Within the scope of the present invention, this information includes , related to longitude on the X axis, latitude on the Y axis, and elevation / height of relief or depth of depressions on the Z axis These topographic configuration data represent the three-dimensional structure 5 formed on the upper surface 13 of the blank 12. It is used for deling. Such modeling of three-dimensional structure 5 is used for this structure 5 Supports digital representation. This modeling forms the three-dimensional structure 5 of the blank 12. Includes a group. In this context, each part of the terrain composition data is the spatial coordinate of a point in this group. That is the case.

[0032] As mentioned above, the algorithm executed by the controller is the acquisition of terrain configuration data. It is beneficial to be involved. In this context, this algorithm is a mathematical function, in particular a polynomial of the z axis. The function increases or decreases the z-coordinate as a function of the nth-order mean of adjacent x and y coordinates in z. To implement the mathematical functions that make up the surface, and the polynomial functions of the z-axis that correspond to the derivative / gradient of the surface. It is composed of the following.

[0033] Next, substep 22 is performed on the computer / data stored in the controller's memory element. The digital file contains this terrain configuration data, and therefore archives this model. We offer the 25 series.

[0034] Manufacturing step 20 involves manufacturing a three-dimensional structure 5 inside / on the top surface 13 of the blank 12. Further includes substep 26. Such substep 26 is particularly of blank 12 This upper surface 13 is implemented by the system that manufactures this structure 5. Includes a control unit, a communication module, and a device for patterning the top surface 13. This patterning device, driven by a motor, uses a machining and / or laser processing module. It may include a module for stamping onto the blank 12 of the dial 2. In this context, manufacturing step 20 is performed by precision laser engraving using a femtosecond laser. This may include a substep of machining the upper surface 13.

[0035] In connection with this, substep 26 is computer / digital including terrain structure data. Phase 27 includes receiving the file, and therefore on the blank upper surface 13 of the dial 2 This includes modeling of the three-dimensional structure 5. During this phase 27, terrain structure data is generated. The controller of the system communicates via the communication module of these two systems. Transmits the user / digital file to the control unit.

[0036] Next, this substep 26 is based on the terrain structure data contained in the received file. This includes a phase 28 in which the top surface 13 of the blank 12 is patterned. Referring to Figure 4, During this phase 28, the control unit generates a three-dimensional structure 5 on the upper surface of the blank 12. Therefore, instructions are generated to drive the processing module based on this terrain structure data. These control commands are used to cubic one point at a time so that the three-dimensional structure 5 fits its model. To reproduce the original structure 5, the processing module is guided into / on the top surface 13 of the blank 12. It makes it possible to guide.

[0037] In another embodiment in which this three-dimensional structure 5 is generated by a stamping module, Note that the module includes a die with markings related to this structure 5. Specifically, this marking indicates that this machining module is intended to receive such a marking. Based on control commands that enable the machined module to be guided on / over the surface of the die, This can be done by a roulette.

[0038] The thickness e1 of this three-dimensional structure generated on the upper surface of the blank shown in Figure 4 is preferably 1 0 1 from 10 3 Please note that this is within the range of μm.

[0039] Such a three-dimensional structure 5 is generated over substantially the entire upper surface 13 of this blank 12. More specifically, this structure 5 extends over 80% or 90% of this upper surface 13. Or it is even generated over the entire upper surface 13. In other words, this three-dimensional structure 5 is generated over the upper surface It accounts for between 15% and 100% of 13.

[0040] Next, this method performs step 29 of processing the surface 14 of the three-dimensional structure 5 of the blank 12. This includes, in the meantime, modifying at least one visual feature of this surface 14. The purpose of p29 is to determine, in a non-limiting and non-exclusive manner, the degree of roughness, brightness and / or of this surface 14. This involves shaping / modifying the visual features of this surface 14, including its color. More specifically, this Step 29 is performed over the entire surface 14, or on at least a portion of the surface 14. This allows for the modification of at least one of these features.

[0041] This processing step 29, in particular, enables the detail of the landscape reproduced by this three-dimensional structure 5. By helping to visualize, the visual aspects of the various zones 6a, 6b, and 6c that make it up To improve cognition, the optical properties of this surface 14 of structure 5 (for example, light on this surface 14) It contributes to correcting reflection, light distribution, and aesthetic characteristics.

[0042] To do this, step 29 is performed on the surface state 14 of all or part of the three-dimensional structure 5. Substep 30 to modify and coating all or part of the surface 14 of the three-dimensional structure 5 Substep 31 includes depositing material 7. Substep 30 modifies the surface of this structure 5. Depending on the treatment applied to 14 or at least one of the parts constituting such surface 14 This can be performed before or after the deposition substep 31.

[0043] The purpose of the modification substep 30 is to non-limiting and non-exclusively determine the degree of roughness of the surface 14. The objective is to modify the features of this surface 14, including and / or brightness and / or color. During substep 30, an operation for processing the surface 14 is performed, for example, dry sandblasting. Wet sandblasting, shot blasting, sunray brushing, sanding, polishing Polishing, satin finish, brushing, chemical etching, or at least two of these actions The combination of these actions is performed. Such actions are performed on the entire surface 14 of the three-dimensional structure 5 or on this surface. This can be performed on at least a portion of surface 14. In other words, such an operation is performed on this This allows for selective modification of the surface 14 of structure 5.

[0044] The purpose of the deposition substep 31 is to correct the color characteristics of this surface 14. This substep 31 may help to correct the roughness and / or brightness of the surface 14. During such substep 31, a coating 7 of a metal or resin type material is applied. An operation is performed to apply to the surface 14 or at least one portion of the surface 14. In other words, this operation selectively applies the coating 7 to the surface 14 of the structure 5. This coating 7 makes it possible to use it. This coating 7 satisfies aesthetic and / or technical constraints. To achieve this, it may consist of a single layer or a set of stacked layers. 7 is 10 -2 From μm to 10 2 Please note that it has a thickness in the range of μm.

[0045] In the case of metallic materials, this can be done by dry or wet methods, such as PVD (Physical Vapor Deposition) or CV (Chemical Vapor Deposition). D (Chemical Vapor Deposition), ALD (Atomic Layer Deposition), LBL (Layer by Layer), By inkjet, by dip coating, by brush, by dispensing By means of a spray, by atomization, or by the sol-gel method, or by chemical method. By means of, or by using at least one operation of an electroplating type electrochemical method, It can be used. Furthermore, such metal materials may be, for example, metal alloys or metal oxides. Please note the following: Specifically, this material is not limited to and not exhaustive, but contains gold, silver, Ruthenium, rhodium, nickel, copper, titanium, chromium, chromium oxide, titanium oxide, oxide It could be silicon.

[0046] This is at least one of the operations of spraying, dipping, or casting in the case of resin-type materials. This can be applied to the surface 14 of the three-dimensional structure 5. Such resin-type materials are permeable It may be light and / or colored. This resin may be acrylic, nitrocellulose, epoxy, or This may be, but is not limited to, polyurethane resins.

[0047] Next, this method creates at least one pattern 4 on the processed surface 14 of the three-dimensional structure 5. This includes step 32, which involves the material constituting the pattern 4. This includes a substep 33 for printing. This material consists of polymers or particles such as resin. These particles can be organic, metallic, organometallic, rocky, luminescent, phosphorescent, or inert particles. The resin may be acrylic, nitrocellulose, epoxy, or polyurethane resin. However, it is not limited to these. This printing substep 33 can be either pad printing or transfer printing. Please note that this is performed using a transfer printing operation, or a screen printing operation. Note that such Pattern 4 can be two-dimensional or three-dimensional. In terms of chronology, Pattern 4 is non-limiting and non-limiting, such as the display of time or date. Marking elements such as time scale numbers or indices, engravings, and pictures involved in the generation of functions. This is a graphic representation that may be related to the image.

[0048] Such pattern 4 can be an invisible pattern that can be exposed upon request. More specifically, this is a fluorescence pattern that becomes visible only when exposed to ultraviolet light. It can be done this way.

[0049] Such a process encapsulates all or part of the surface 14 of the three-dimensional structure 5. This also includes step 34. During this step 34, the encapsulation layer 8 spreads over the entire surface 14. or apply only on top of at least one of the aforementioned patterns 4. This layer 8 is preferable The thickness of the layer is greater than the thickness of pattern 4. The thickness of such a layer is from 1 μm. The thickness is between 500 μm. Such encapsulation layer 8 is preferably made of a resin such as epoxy resin. It is formed from fat. Alternatively, this resin can be acrylic, nitrocellulose, or polyurethane. It may be made of resin. Applying such a layer 8 to this surface 14 is particularly important over time. It protects against wear and tear from excessive use and improves the visual appearance of the three-dimensional structure by adding depth. Please note that this will be helpful in [doing something]. Furthermore, a dial decorated in this way will protect against shocks and [unclear] Depending on the circumstances, it is highly likely that the external components are exposed to corrosive environments (moisture, dust, etc.). Therefore, such a layer 8 helps to improve robustness.

[0050] Next, this method completes / finishes blank 12 to obtain this dial 2. This includes step 35. During this step 35, for the assembly of the watch case 13 This blank 12 is processed to adjust the size as needed, needle 1 To create a through-opening for the shaft passage to drive 5, relative to dial 2 The machining operation performed, the operation to polish the blank 12, the exposed portion of the blank 12, that is Galvanic treatment operation to protect exposed parts of the substrate during processing, acrylic, ni Directly transfer the encapsulation layer using cellulose, polyurethane, or epoxy resin. If the operation has not yet been performed, such as the appliqué / indexing operation, The lifting motion is performed.
