Definitions

  • the present invention relates to a sealed housing closed by a glued or welded ice, in an arrangement that makes it possible to make the joint invisible and / or to obtain a decorative effect.
  • the invention relates more particularly to the case of a timepiece in which the ice, which constitutes the protective element of the underlying displays, must not detract from the overall aesthetic, or even on the contrary participate in a giving a greater freedom in shades and shades.
  • the usual technique is to metallize the inner part of the ice in the area where it is desired to form the seal, to deposit a bead of glue on the corresponding part of the box, then to assemble the ice by pressure.
  • Metallization is mainly to hide the glue joint which can present from the beginning a more or less regular contour, making it visible to the naked eye. The metallization also makes it possible to mask the phenomena of aging of the adhesive joint, such as shrinkage or yellowing.
  • the process consists basically in depositing a layer of attachment for example chromium, then by evaporation various metals (Cr, Ti, Pd, Au, ...) or alloys to have a fairly large palette of shades that all have a metallic tone.
  • Metallization does not make it possible to obtain non-metallic matte shades and even less white, which has the disadvantage of limiting the choice of colors for the box or its covering.
  • the U.S. Patent 4,623,262 describes a timepiece comprising an ice provided on one of its faces with a decorative outer layer of hard material and / or a weld layer with an interposition of a fastening layer.
  • the patent application US 2002/0184920 discloses a method for making glass decorative strips for covering, for example, floors or walls. This process comprises the steps of shaping a glass bar by removal of material in order to configure the bar according to the profile of the decorative strip that is to be produced, to apply to the bar a color glass frit and to heat the bar of glass at a predetermined temperature and for a determined time.
  • the request for FR 2750 419 discloses a method of enameling glass substrates in which a layer of an enamel composition is coated with a glass substrate by ejecting droplets of an enamel composition from openings made in glass heads. inkjet printing and directing the droplets to the printing points of the glass substrate.
  • the present invention therefore aims to overcome the disadvantages of the aforementioned prior art by providing a housing on the opening of which is fixed an ice whose seal with the scope of the opening is not detectable and has the same shade as the housing, or whose said seal allows on the contrary to have a modular aesthetic appearance.
  • the invention relates to a housing comprising a middle and a bottom defining a compartment formed by an ice made of a transparent material resistant to a temperature greater than 500 ° C, said ice being bonded or welded at the zones of joints covering at least partially the scope of the middle part, thus leaving visible at least part of the middle part.
  • the casing is characterized in that the inner face of the ice comprises an enamel deposit in the joint areas for assembling the ice on the scope of the caseband by gluing by applying a film or points of glue, or by welding.
  • the transparent material resistant to a temperature greater than 500 ° C may be a mono or polycrystalline material, for example a quartz, a spinel or a corundum, in particular sapphire. It is also possible to use an amorphous material, such as an inorganic glass, insofar as its softening point is greater than the temperature necessary to effect enamel deposition.
  • the deposition of an enamel layer on an ice in a material of a similar chemical nature makes it possible to have a very strong adhesion of said enamel layer, practically eliminating any risk of tearing after gluing, or welding.
  • the material used to form the middle part is ceramic, that is to say a material having the same palette of hues and shades as the enamel.
  • the compartment of the housing contains a watch movement and a dial to form a timepiece, such as a wristwatch.
  • the processes used to carry out enamel deposits at the joint zones make it possible to delimit said zones precisely, and to selectively deposit, if desired, enamel layers of hues. different.
  • the enamel deposits can be made in ice edge recesses, the leveling being achieved by subsequent polishing.
  • the enamel deposits can also be made in excess thickness, by direct deposition or by chemical structuring, especially when the edge of the ice is thin.
  • FIGS. 1, 2 and 2A to 2C a first embodiment according to a first method is described below.
  • the wristwatch shown in Figures 1 and 2 comprises in known manner a housing 1 formed of a middle part 3 closed at its bottom by a bottom 5 and at its upper part by an ice 10 delimiting a sealed compartment 7.
  • the compartment 7 can accommodate a watch movement 8 allowing the display 9.
  • the display is an analog display by means of hour hands 9a, minutes 9b and seconds 9c.
  • the ice 10 covers the entire span 4 of the middle part 3 on which it is glued or welded at a joined zone 15 consisting of an enamel deposit 20 formed on the inner face 11 of ice 10 level of its outer edge 12, covering in this example all the scope 4 of the caseband 3.
  • the hue visible by an observer through the ice 10 at the level of the scope 4 of the middle part 3 is the color of the layer of Enamel 20.
  • the middle part is made of ceramic, or has a ceramic covering, it is then very easy to find exactly the same enamel shade so that the joint area is not perceptible by an observer.
  • a recess 14 is made in the outer edge 12 of the glass 10 by means of a diamond wheel to a depth of, for example, between D, 1 and 0.5 mm.
  • Enamel deposition is carried out in one or more steps by the known techniques of dipping, sputtering, or screen printing, each step being followed by baking until a thickness slightly greater than the desired final thickness is obtained.
  • a third step ( Figure 2C ) the ice is reworked and polished by traditional means so as to eliminate any excess or overflow of the enamel and to perform machining ribs to achieve a well-defined geometry, both in terms of enamel filling and the edge external 12.
  • ice 10 is applied to the surface 4 of the middle part 3 with the interposition of a glue film (not shown).
  • a glue film not shown.
  • the figure 3 represents in section a variant in which the enamel deposit is made only above a portion of the scope 4 of the caseband 3, preferably in the form of a band near the edge of the ice 10 to guarantee the seal.
  • Parts not coated enamel can be left in the state to let appear through transparency through the ice color of the middle part. These Parts may instead be metallized 17 for aesthetic purposes, after forming the enamelled areas.
  • FIG. 5A to 5G illustrates the example of a flat ice. but it is obvious that the same process can be applied to a convex mirror.
  • This method has the advantage of giving a great freedom in terms of the shapes of the joint areas.
  • a partial metallization 18 inside the portion of the ice 10 to be positioned above the scope 4 of the caseband 3.
  • the structuring then makes it possible to perform enamel deposition 20 in the parts not metallized.
  • the deposition can be carried out over the entire range, allowing the metallized parts to appear by transparency.
  • the metallized portions form two threads giving an impression of continuity with the outer edges of the bracelet strands 2a, 2b of metal, and the enamelled parts have a hue in harmony with the bracelet links made of ceramic.
  • the invention is not limited to a timepiece: it can for example find an application in the manufacture of the cover of a jewelery box.
