Definitions

  • the present invention relates to a wristwatch case comprising a middle part taken from a portion of a rigid strip section, said middle part comprising an opening for receiving the movement.
  • Document CH-A-492244 describes a process for the mass production of watch cases obtained from a band of rectangular section. In this process, we start by drilling pilot holes in the strip, these holes constituting drive and centering means for all subsequent operations. A cap is then formed by cold stamping by means of a die and a punch, this cap forming the watch case itself. The horns are released by cutting, the ice notch is machined by turning, the horns are bent, then the holes necessary to receive the winding stem and the strap attachment bars are drilled, finally the box is separated. the band. The whole is achieved by an installation allowing the step-by-step advance of the strip and its positioning at each work station.
  • the watch case thus produced has several drawbacks.
  • a watch case meeting the generic definition of the present invention is described in document CH-A-294064.
  • This box is made from an extruded profile in the form of a tube where horns which will be used to attach the bracelet are extruded at the same time as the tube.
  • the tube is cut into slices and the slices thus obtained are machined to obtain the desired build.
  • This system is relatively expensive to implement and above all does not make it possible to obtain, directly from the profile, an elongated relief structure in a direction perpendicular to the axis of the opening presented by the tube since the profile used is a tube and not a strip as in the present invention.
  • GB-A-887130 shows how to make a watch bezel from a simple extruded tube where the horns are formed from legs welded along the tube.
  • Document FR-A-2329002 describes for its part a watch case comprising a bezel made of folded sheet metal comprising two hooking edges thanks to which an ice and a container bottom are assembled elastically. There is no relief structure there which would have come from a rigid strip profile, as is the case in the present invention.
  • Document CH-A-354034 relates to a movement plate obtained from a flat band which is cut into square elements, these elements then being heated and then struck.
  • Document EP-A-0105841 relates to a metal grid intended to support components for a watch and also obtained from a flat band.
  • Document CH-A-346177 describes a curved watch case where the emphasis is on the strap attachment but where nothing indicates that this box is made from a strip profile.
  • WO-A-8604696 describes a case-case back, the bottom of which is provided with a dovetail-shaped groove in which a support of the same shape can be introduced.
  • a front view of this background shows a polygonal outline allowing to say that said background is not made only from a strip profile.
  • Document EP-A-0015242 shows decorative inserts adorning a watch case. These inserts are fixed by means of studs riveted or clipped in round openings made in the box thereby indicating that the box is not made from a strip profile.
  • the middle part according to the invention is characterized in that the opening receiving the movement is made perpendicular to the longitudinal direction of the band from which the middle part has come out and that this middle part has a relief structure coming from the strip and elongated in said longitudinal direction.
  • the invention also extends to a strip profile for the manufacture of watch case middle parts, as well as to the process for the mass production of such middle parts.
  • one of the objects of the invention is to propose a middle 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.
  • 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.
  • Another object of the invention is to use said relief structure to serve as means of attachment to the middle of decorative and / or functional inserts, the latter making it possible, for example, to attach the crystal to the middle.
  • the middle 1 shown in Figure 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 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
  • 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-643425.
  • the slides 8 come from the projecting structures 3.
  • the elongated recesses 11 which serve as means of attachment to the strands of a bracelet, the end of each of these strands having then beads which thread into the recesses 11.
  • 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 presents a middle part 1, the recesses 23 of which come from the strip profile, serve as means of attachment to rounded rods 24. It will be noted that in this variant, the bracelet fixing means are horns 25 produced after 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 produced 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.
