Definitions

  • the present invention relates to a device for adjusting the orientation of a crown to a watch with respect to the watch, said ring being able to take a unscrewed position and a screwed position relative to the middle part of a tube fixed to the middle part .
  • the present invention also relates to a watch comprising such a device.
  • screw crowns on watches are well known.
  • the crown can take a unscrewed position in which it is possible to set the time of the watch, the date etc. and a screwed position, which is the position in which the watch is worn, in which the crown is tightened and locked on the tube of the watch.
  • a problem with conventional crowns is that it is very difficult, if not impossible, to orient permanently during production, the corresponding threads of the middle part of the watch and the crown of that, for each watch produced, the screwed crown, is always in the same position relative to the middle part. This can be problematic if the shape of the crown is not symmetrical in particular, or if the crown has a particular logo: the position of the crown or the logo relative to the caseband is then different for each watch produced, once that the crown is screwed.
  • the document CH 242,198 discloses a sealed crown winding screwing on the box and having, inside an axial tube, a coupling device with the winding stem, arranged and shaped so that said crown can perform, when unscrewed , reassembly and time setting functions.
  • the axial tube is fixedly attached to the ring gear and has, at its opposite end to the ring gear, a part projecting inside and constituting one of the elements of the coupling, the other elements of the coupling being introduced. in the tube before fixing it to the crown.
  • the object of the invention is to improve the known devices.
  • the object of the invention is to propose a simple system which makes it possible to fine-adjust the position of the screwed crown relative to the middle part, while preserving the sealing qualities of the watch.
  • the claim 6 defines a watch comprising a device according to the invention.
  • the figure 1 shows a sectional view of a first embodiment of the invention.
  • the figure 2 shows a sectional view of a second embodiment of the invention.
  • the first embodiment of the invention is shown by way of example.
  • a ring 1 which is screwed onto a tube 2, said tube being itself fixed to the middle part 3 of the watch.
  • This crown may further comprise a logo 4, schematized by dashed lines.
  • several seals are placed between the ring and the tube to seal, namely an O-ring 5 and a first flat seal 6 which is compressed when the crown 1 is screwed onto the tube 2.
  • the crown 1 is screwed onto the tube 2 by means of a suitable thread 7 in the ring 1 and a corresponding thread 8 on the tube 2.
  • the means for adjusting the position of the ring 1 relative to the middle part 3 of the watch comprise a ring 10 which is placed between the middle part 3 and the tube 2.
  • this ring 10 is formed in a shape memory metal alloy, for example a nickel-titanium alloy such as the "Micro-Niti" alloy from the company Microfil Industries SA. Thanks to this intermediate ring, a system is obtained which enables An angular adjustment of the crown 1. In fact, by appropriately using the shape memory effect related to the temperature, it is possible to realize a system allowing a fine adjustment which is independent of the start of the thread 8 of the tube 2. and the beginning of tapping 7 of the ring 1.
  • the ring 10 completely closes the connection it makes between the middle part 3 and the tube 2, at room temperature and despite normal temperature differences that could be experienced by a watch being worn.
  • the rotation of the tube 2 is blocked and the position of the ring 1 screwed relative to the middle part 3 is fixed.
  • the figure 2 shows a second embodiment of the invention, in which, the elements identical to the first embodiment have the same references, the main difference residing in the position of the ring 10 of the figure 1 .
  • the ring bears the reference 11 and is not between the tube 2 and the middle part 3 (see figure 1 ) but between the ring 1 itself and the tube 2.
  • the tube 2 is driven conventionally in the middle part of the watch (not shown), and it is the ring 11 itself that supports the tapping 12 of the ring 1 which is intended to be screwed on the thread of the tube 2.
  • shape memory alloy ring is a non-limiting example. Other alloys are possible. Similarly, other equivalent systems allowing in particular to temporarily create a game between the crown and the middle part of the watch are possible, the idea being to allow such a game that in particular conditions and to prevent it under conditions normal use.
