Definitions

  • the present invention relates to a device for attaching the strands of a bracelet to a watch case comprising a crystal and a middle part, said device comprising horns attached to the middle part and bars for assembling the horns to the strands of the bracelet. so as to allow the articulation of said strands on said horns according to the preamble of claim 1.
  • Lugs have often been brought back afterwards on the middle.
  • this mode of operation greatly facilitates the execution of the box both for machining and for termination, since the middle can be machined on the lathe without this machining being able to be hampered by horns which would be an integral part of the middle.
  • Such an embodiment is described for example in document CH-A-321188 where the middle part has a circular groove in which is engaged an arcuate part of each horn which can be held in place in this groove in two ways.
  • the first way is to give the section of the groove and of the arched part of the horn a shape which makes it possible to hang this horn on the middle and to hold it in place by a telescope.
  • the other way is to fix the horns to the middle by screws which cross their arched parts and whose heads are masked by the telescope. In both cases this process requires relatively complicated machining of the horns first for the part engaging in the groove and then for the visible and curved part of the horn which receives the bracelet.
  • the object of the present invention is to provide a fastening device, the attached horns of which can be produced in a much simpler manner than those described in the documents cited above.
  • the fastening device also comprises horns which each have a portion inserted in a blind housing presented by the middle part of the box and pins introduced in the first holes made in this middle part and passing through the horns for rigidly fix these to the box and the desired goal is achieved thanks to the fact that in this device each horn comprises at least two thin plates cut into shape, juxtaposed and having second holes through which one of the pins passes as is defined in the characterizing part of claim 1.
  • a device for attaching a bracelet to a watch case which comprises for each strand or each end of this bracelet an element formed of two parts juxtaposed, a portion of which is introduced into a housing of the middle part of the watch to assemble this element with the middle part and a bar for attaching the strand or the end of the bracelet to this element.
  • the element in question is not a horn which is rigidly fixed to the middle part by a pin but an element which is held by a pivot around which it can rotate so as to be movable above the box and this in order to facilitate the fixing of the watch to the wrist.
  • the parts of the element which are only two in number are necessarily thick parts which cannot be obtained simply by stamping but, for example, by milling. If these parts were thin, they would not be able to withstand for a long time the flexural and torsional stresses to which they would be subjected when the watch was attached to the wrist and while this watch was being worn.
  • the juxtaposed thin plates are rigidly linked to the middle part and, consequently, between them and the number of plates per horn can be chosen according to their thickness, the number of horns, etc., which means that these horns can be as solid as conventional solid horns.
  • FIG. 1 shows a wristwatch comprising a box 3 to which two strands 1 and 2 of a bracelet are attached.
  • the box 3 comprises a middle part 10, a crystal 9 through which there are needles 12 for displaying the time and a bottom 11.
  • the attachment device comprises for each of the strands 1 and 2 a horn 4 which is attached on the middle.
  • a bar 5 assembles the horn to the strand so as to allow, in a manner known per se, the articulation of the strand on the horn.
  • the horn 4 comprises at least two plates 6 cut in shape and juxtaposed and then partially introduced into a blind housing 7 made in the middle 10.
  • a pin 8 is received both in a hole 14 made in the middle part and in second holes 15 made in the plates to fix the horn to the box.
  • blind housing is meant here a housing made in the thickness of the middle and leaving material between the inside of the box and the outside thereof. This housing has a bottom 25 (see Figure 3).
  • FIG. 3 which is a section along line III - III of Figure 1, shows how is adjusted a plate 6 of the horn 4 relative to the middle 10.
  • the middle 10 we practice the blind housing 7 which has the bottom 25. The plates are then introduced into the housing, then the pin 8 is chased first in the first hole 14 made in the middle part then in the second hole 15 made in the plate and finally in the first hole 14 made in the middle (see also Figure 1).
  • FIG. 3 also shows that the strand 2 of the bracelet is fixed to the horn 4 by means of the bar 5 introduced into a hole 16 made in the plates 6 of the horn 4.
  • Figures 1 and 3 also show that we can take advantage of the presence of the horns 4 to seal the glass 9 on the middle 10.
  • the plate 6 has a projection or overhang 17 which bites on the glass and presses it on the middle.
  • the seal is ensured by a lining 13 pinched between the crystal and the middle part.
  • FIG. 4 is a section showing an alternative embodiment of the section illustrated in FIG. 3. The only difference consists in fixing the glass 9 in a housing 26 located on the top of the middle part 10, a seal 27 ensuring the tightness, the plate 6 contributing in no way to the fixing of the crystal on the middle.
  • FIG. 2 shows a front view of a second embodiment of the fastening device according to the invention.
  • each strand of the bracelet is attached to the case 3 by means of two horns 4 each having two plates 6.
  • the plates are fixed in a similar manner to what has been described above.
  • Figures 1 and 2 also show horns 4 made of a plurality of plates 6 cut and juxtaposed.
  • the plates forming the horn all have the same cutout.
  • each horn is formed of three plates 30, 31 and 32 whose cutouts are different and this in order to seek an original aesthetic. If the three plates are fixed to the box by the pin 8 already described above, the strand 2 of the bracelet is only attached to the horns 4 by the end of the plate 32 by means of the bar 5.
  • the embodiments which have been described show that the device claimed and using cut plates, allows a host of variants by which the final appearance of the watch can be modified.
  • the plates can be cut from the same strip by means of a stamp. In this case all the plates would have the same coloring.
  • the base material can be steel or gold. We can also consider alternating two materials, for example steel and gold to obtain a two-tone appearance. Whatever the material used, it will be noted that the plates forming the horn are easy to produce, without complicated machining, since they come from stamping. Therefore, the fastening device is inexpensive while presenting an attractive and new appearance.
  • FIG. 8 shows a particular embodiment of the plate 6.
  • the support zones 18 and 19 the projection 17, the clearance 21 and the holes 15 and 16 respectively receiving the pin for fixing the plate to the middle part and the strap strand for attaching the bracelet to the plate.
  • the plate has a recess 20, cut at the same time as the external contour of the plate, this recess allowing a saving of material, particularly if the plate is made of gold.
