Definitions

  • the present invention relates to a wristwatch case comprising a middle part emerging from a strip profile portion.
  • the watch case thus produced has several drawbacks. First of all to present a mediocre appearance since the case and particularly the bezel that surrounds the glass comes from a flat strip offering no decor. The disadvantage then of requiring costly recovery operations if only for fixing the crystal and / or the back, if such a removable bottom is considered essential for accessing the watch mechanism. Finally, that of requiring the use of bars for attaching the bracelet, at least in the proposed embodiment.
  • Document FR-A-2 329 002 for its part describes a watch case comprising a bezel made of folded sheet metal comprising two hooking edges by means of which a glass and a container bottom are assembled. There is no relief structure there which would have come from a strip profile as is the case in the present invention.
  • the middle part according to the present invention is characterized in that it has a relief structure coming from the strip and elongated in the longitudinal direction of said strip.
  • the invention also extends to a strip profile for the manufacture of watch case middle parts, as well as to the method for the mass production of such middle parts.
  • one of the objects of the invention is to propose a middle part for a watch case which is taken out of a portion of a strip profile having a relief structure used as decoration for said middle part.
  • Another object of the invention is to use said relief structure to serve as a means of fixing to the middle part of elements forming part of the watch such as, for example, the crystal and / or the back.
  • Another object of the invention is to use said relief structure to serve as an attachment to a bracelet.
  • the middle part 1 presented in FIG. 1 shows a first embodiment according to the invention.
  • This middle part is produced from a strip profile shown, on a reduced scale, in FIG. 2.
  • the middle part has a relief structure which came from the strip 2 and which is elongated in the direction longitudinal of said strip.
  • relief is meant here the shape of a surface which includes projections and / or depressions.
  • the projections 3 define slides 6 facing each other and into which is introduced a glass (not shown).
  • the projections 4 are elongated beads which each serve to attach to a half-bracelet (not shown).
  • FIG. 1 there are also recesses referenced 5 and 6, the recesses 5 being arranged for example to allow a winding stem to pass and the recesses 6 forming the slides of which we have just spoken.
  • These projections and recesses are already part of the band 2 from which the middle part 1 is extracted, as can be seen in FIGS. 1 and 2. To remove the middle part 1 from the band 2, it suffices to make the opening 7 (intended to receive the movement) and to cut the strip.
  • Figures 1 and 2 also show that the middle part 1 is output from a strip section portion 2 having a camber substantially perpendicular to the longitudinal direction of the strip.
  • the camber is already existing in the profile itself. It is clear, of course, that this camber might not exist and that at that time the build would be flat. Without it being necessary to illustrate it, the strip 2 could also be bent mechanically parallel to the longitudinal direction of the strip. Likewise, the band could present both of the two camber in question, which would give the middle part a cap shape. Finally, one or the other of the camberings, or both, could be made after the middle part has been separated from the band.
  • Figure 3 shows a middle of shape very similar to that described in Figure 1.
  • the glass is introduced between two slides 8 each of which has parallel faces 9 and 10.
  • the manner of fixing the glass thereon is described for example in document CH-A-643 425.
  • the slides 8 come from the projecting structures 3.
  • Figures 1 and 3 show that the axis 3 a.m. - 9 a.m. of the watch coincides with the longitudinal direction of the profile.
  • Figure 4 which is another variant of the middle, shows that it is the axis from 12 a.m. to 6 a.m. of the watch which coincides with the longitudinal direction of the profile, the strap 12 emerging from the middle in the direction of this profile.
  • Figure 5 shows a second embodiment of the invention. It is a watch in which the movement and the glass are mounted.
  • the middle part 1 is also taken out of a portion of a strip profile in which the relief structure, coming from the strip, includes projections 13 defining slides 14 facing each other, slides in which the bottom 15 is inserted.
  • the strands of the bracelet are attached to the middle in the same way as that described with reference to FIG. 3.
  • FIG. 5 also shows relief structures 16 in hollow which define purely decorative patterns.
  • Figures 6, 7 and 8 show a middle part of a watch case according to a third embodiment of the invention in which the profile is structured to receive inserts.
  • FIG. 6 shows a watch case comprising a middle part emerging from a portion of a strip profile, said middle part comprising a relief structure comprising recesses 20 into which are inserted inserts 21 which serve as means of fixing a lens (not shown) in the middle 1.
  • the glass is pinched between the middle 1 and the inserts 21. It is obvious that the inserts themselves could also have come out of a strip profile.
  • FIG. 7 shows a middle part 1, the recesses 23 of which come from the strip profile serve as means of attachment to rounded rods 24.
  • the bracelet fixing means are horns 25 produced after the fact by milling.
  • Decorative strips 24 can be made in gold.
  • Figure 8 differs from Figure 7 in that the recesses 26 in which are threaded the decorative strips 27 have a triangular shape.
  • Figure 9 finally shows a fourth embodiment of the invention in its simplest sense.
  • the middle part 1 is taken out from a strip profile, the relief structure of which is elongated in the longitudinal direction of the strip consists in giving the upper face 30 of the middle part a radius of curvature smaller than the radius of curvature of the face lower 31 of this middle part.
  • the underside could be flat.
  • FIG. 9 also shows that the middle part is provided with a hollow relief structure 32 which defines an indication of source.
  • the groove 32 as presented, cannot be produced other than in a strip profile and that its presence attests that the middle part was manufactured according to the present invention.
  • strip profile is linked to the concept of manufacturing this strip which is obtained for example by extrusion, drawing or rolling.
  • a band can be made in the most diverse materials ranging from plastic to ceramic, passing for example through aluminum, brass, steel and precious metals.
  • FIG. 10 briefly shows the steps for manufacturing the middle part according to the invention.
  • a strip profile 2 is provided as shown in perspective in FIG. 1.
  • the strip 2 in FIG. 10 is a top view, on the glass side of the watch. Are apparent the fastening means 4 of the bracelet and the projections 3 in which the ice will pinch.
