Definitions

  • the present invention relates to a timepiece, and it relates more particularly to new developments relating to transparent and visible elements from the outside of the part, such as for example glass.
  • the invention proposes to realize outer layers of hard material, which can for example but not exclusively mask the high temperature solder connections established according to the first aspect of the invention.
  • the invention makes it possible to reach breaking loads at tearing of the coating greater than 15 kg / mm 2 which become comparable to the tensile strength of the sapphire itself, which is between 19 and 50 kg / mm 2 depending on the direction of the tensile force.
  • FIG. 1 there is shown a partial section of a sapphire crystal or mineral glass 1 forming a component of a timepiece according to the invention.
  • This glass 1 comprises in particular an adherent coating 2 ensuring the attachment of an outer decorative layer 3, and an adherent coating 4 ensuring the attachment of a layer of high temperature solder material 5.
  • the decorative layer 3 consists of a hard material, for example metallic, of the carbide or titanium nitride type which, in addition to their high hardness which allows them to retain a shiny appearance due to their scratch-resistant nature, have shades very close to those of gold.
  • a hard material for example metallic, of the carbide or titanium nitride type which, in addition to their high hardness which allows them to retain a shiny appearance due to their scratch-resistant nature, have shades very close to those of gold.
  • other materials could be used, and in particular carbides, borides or nitrides of metals such as tantalum, tungsten, chromium or other compounds having an adequate appearance and hardness.
  • the adherent coating 2 it may comprise a single layer adhering to the glass and ensuring a good bond with the decorative layer 3 or several layers 6, 7 having good cohesion between them, the bottom layer 6 adhering to the glass 1 and the outer layer 7 adhering to the decoration layer 3.
  • the layer 6 can be formed of aluminum oxide AI2 03, the layer 7 being a layer of chromium and the layer decoration 3 being formed of titanium nitride.
  • the adherent coating may be formed of titanium oxide Ti0 2 , which is subsequently coated with nitride or titanium carbide TiN or TiC.
  • the adherent coating 4 may consist of one or more layers (8, 9, 10) superimposed on different materials.
  • the layer 8 ensuring the attachment of the coating on the ice 1 is constituted by aluminum oxide A1 2 0 3
  • the layer 10 ensuring the attachment of the solder layer 5 is a layer of carbide of tungsten
  • an intermediate layer 9 of tungsten provides the connection between the two layers 8 and 10.
  • oxides for the layer in contact with the ice has proved to be particularly advantageous.
  • high temperature solder material forming the layer 5 is meant a filler material capable of being applied in the solid state between the coating 4 and another element of the timepiece, then brought to melting at a temperature of the order of 550 ° C to 600 ° C or more, depending on the nature of the elements to be combined, so as to form a permanent bond between these elements after cooling.
  • Such materials are widely used and used for example for welding steel parts. Their breaking load is much higher than that of materials, of welding at low temperature, and most often greater than 60 kg / mm 2 . Their resistance to oxidation under normal conditions of use of a timepiece is also much higher.
  • FIG 2 there is shown in partial section a watch case 11 provided with a crystal 12 on which have been fixed an outer decorative layer 13 and an annular middle part 14 welded to the crystal 12 by means of a solder layer 15.
  • the glass has been prepared in accordance with the preceding explanations to allow the attachment of layers 13 and 15.
  • a base 16 is removably mounted under the middle 14 by means of screws 17.
  • the fixing by welding of the middle part 14 on the glass 12 can be obtained, after the production of the adherent coatings on this glass, by placing the welding material 15, which for example forms a frame of suitable dimensions, between the two parts to be assembled, then by placing the assembly thus formed in an induction furnace.
  • Figures 3 and 4 showing a coated glass according to the invention in top view, and they illustrate the cases where a decorative layer forms either an annular frame 18, or false bezel, on the periphery of the glass, which can be bevelled as in FIG. 1, either fancy patterns 19 intended, for example, to hide the elements for fixing the glass of FIG. 8.
  • FIG 5 there is shown an exploded view of another embodiment of a watch case according to the invention, in which a sapphire crystal 20 is provided with side walls 21 fixed to this crystal by a weld at high temperature.
  • the walls 21 are also made of sapphire, and the assembly thus formed is in turn subject to a metal element 22, also by high temperature welding, to form a watch case.
  • FIG. 6 shows in partial section another watch case according to the invention, in which a crystal 23 serves as a support for the middle part 24 and for the fastening members 25 of the bracelet.
  • the middle part 24 and the fixing members 25 mounted on two opposite sides of the glass 23 are fixed to the latter by high temperature welding.
  • FIGS 7 and 8 show respectively in section and in top view the side edge of a crystal 26 provided with holes in which are welded metal wires 27 forming strap attachments.
  • FIGS. 9 and 10 there is shown respectively in partial section and in top view a watch case in which the crystal 28 is removably attached to a middle part 29 by means of fastening members 30, four in number by example, welded at high temperature under the ice, and which have hooking surfaces 31 collaborating elastically with protuberances 32 of the inner surface of the middle part 29 to maintain the assembly.
  • Figures 11 and 12 there is shown respectively in elevation and in top view a glass 33 on which are welded decorative decorative elements 34.
  • these are made of hard metal.
  • FIGS 13 and 14 show in perspective glass 35, 36 made of several elements assembled by high temperature welding. In this case, it is clear that the facing surfaces of the elements assembled two by two will receive the same adherent coating.
  • FIG. 15 represents in partial section a watch case in which the crystal 37 is assembled to a middle part 38 by a high temperature weld like the box of FIG. 2 for example, but in which in addition fastening members 39 of the bracelet , made of sapphire, are welded by the same process to the middle part 38.
  • FIGS. 16 and 17 other constructions have been shown, where the invention is used to secure a crown 40, 41 on a time-setting rod 43.
  • the crown 40 is provided with a hole 42 whose walls are previously covered with an adherent coating and in which the rod 43 is welded.
  • the end of the time-setting rod 44 of FIG. 17 is welded directly and at the end to the center of the crown 41, also previously coated as indicated above.
  • FIG. 18 illustrates another embodiment of the invention, in which an adherent coating is provided on the surface of the links 45 of a sapphire watch strap, to allow the welding of the articulation members 46 of this bracelet, constituted for example by metal tubes provided for the passage of articulation axes.
