Definitions

  • the present invention relates to a watch case comprising a case whose at least one opening is closed by a telescope and / or an ice, or by a bottom, and in which at least one of the closing elements of the opening is connected at the middle part by an elastic metal member in the form of a ring or endless frame and of recessed straight section defined by the contour of a non-rectilinear wall of controlled thickness, the ends of which are integral with the periphery of said closure element, respectively of the middle part.
  • the documents CH630220 and CH686600 describe means for moving an ice at variable frequencies by means of an electromagnet or a piezoresistive element. There is mention of a thin annular ring which makes it possible to elastically suspend the ice. The mobility of the ice relative to the middle part is very limited both in the plane of the ice and in the plane perpendicular to the ice, and the watertightness is not guaranteed by the construction.
  • WO 2008027140 describes a mobile (tilting) bezel to activate different functions.
  • the mobility of this bezel is due to a piece of rubber or polyurethane, which however does not provide the seal and which we can doubt the reliability in the long term.
  • the object of the present invention is to give a controlled freedom of movement in direction and amplitude to the closure element mounted on the caseband, bezel and / or ice or bottom, depending on the role that one wishes to give to this closure element.
  • the subject of the present invention is a watch case according to claim 1.
  • the profile of said wall comprises a plurality of alternating annular folds whose number is between 1 and 10.
  • the thickness e of said wall is constant and is between 10 .mu.m and 200 .mu.m, the width a of the annular fold is between 0.2mm and 4mm, the pitch p of the annular fold being between> 40 .mu.m and 2.5 mm, to give said closure member freedom of movement, stiffness and orientation controlled with respect to the plane of the opening.
  • the ends of the profile of said wall are sealingly connected to the periphery of said closure element, respectively of the middle part.
  • seals are mounted between the respective cylindrical ends of said wall adjacent to cylindrical seats of said closure member, respectively of said middle and compression rings or frames in view of to seal the box.
  • Metal bellows are thin metal wall elements with a carefully chosen profile to provide flexibility, stiffness and resistance data to the set. There are several types of metal bellows: rolled, hydro-formed, chemically deposited, electro-formed, this list being non-exhaustive.
  • Electro-formed bellows are particularly interesting. Their manufacturing technique is more than 150 years old, but it is only in recent years that components with complex geometries of low thickness (of the order of ten microns) and well controlled have been obtained.
  • the challenge in thickness control is to play with deposition parameters (eg interelectrode distances, nature of electrodes, agitation and bath chemistry, etc.) so as to minimize variations in thickness due to variations. of current density along a geometry with strong changes of curvature.
  • the precise control of the geometry and the thickness makes it possible to develop bellows with adequate stiffness and able to give the closing element of the opening of the middle part a freedom of movement with respect to the plane of this opening.
  • the companies Servometer or Nicoform are examples of suppliers of miniature electro-shaped bellows. These bellows are described for example in the US 3'187'639 and US 5,932,360 .
  • the websites www.servometer.com or www.nicoform.com also give a lot of information about the technique and the materials
  • bellows can be assembled to other rigid parts to facilitate their integration. It must be ensured that the chosen methods of assembly and the materials used are adapted to the stresses that will undergo the assembly without the associated function being pejorated.
  • the assemblies can be made by bonding, brazing or welding by electron bombardment or by laser. If, for example, it is desired to guarantee a seal, the bonding or a solder with tin may prove to be insufficient. In addition, depending on the materials used, too high a temperature in the process can degrade their properties. If the stresses require good corrosion resistance, care must be taken to use suitable materials or pairs of materials.
  • the form of execution illustrated by the figure 1 relates to the attachment of a watch crystal 1 to close the upper opening of a middle part 2 of a watch case.
  • the watch glass 1 is connected to the middle part 2 by an elastic metal member 3 in the form of a ring of recessed straight section defined by the profile of a non-rectilinear wall of constant thickness, constituting a metallic bellows whose ends 3a, 3b are integral with the periphery of the glass 1, respectively of the middle part 2.
  • An annular seal 4 surrounds the periphery of the ice as well as the end 3a of the metal bellows 3.
  • the other end 3b of the bellows 3 is fixed in the same way against a cylindrical portion of the middle 2 by an annular seal 6 compressed by a titanium ring 7.
  • a bezel 8 is fixed on the middle part by a ring 9 fixed against a carried on the external lateral face of the titanium ring 7.
  • the ice 1 is held only by one end of the bellows 3, so that it is suspended elastically on the middle part 2.
  • This assembly can then act as a shock absorber; it may be able to switch to enable functions; or else serve as speaker, pressure sensitive system (balance, barometer, etc.), without this enumeration is limiting.
  • the figure 5 illustrates a bellows 23 incorporated between the middle part 24 and the glass 21, under the bezel 28, with a stamp or a gong 25 and a deflection element 26 of the patch or gong towards the ice 21 and a bearing element 29 against the ice 21.
  • the attachment of the ice with a flexible bellows makes it possible to transmit to the outside vibrations generated inside the box (or conversely), while preserving the tightness of the box.
  • the ice-shield assembly may advantageously be sized so that its natural frequency is at higher values than the frequency band of the transmitted signal (from 100 to 4000 Hz for example); this one does not find it thus degraded nor modified (distortion).
  • the geometry of the bellows does not in any way harm the aesthetics of the room and can be integrated easily.
  • the thickness of the wall of the bellows is of the order of 50 microns, which guarantees a sufficient lateral robustness.
  • protections are nevertheless provided by the presence of vertical stops b1 and b2 or side b3 to prevent damage to the system during very strong external stresses.
  • FIG 6 Referring to a variant in which an annular bellows 33 is disposed between the bottom 40, to which it is fixed by welding, and the middle part 34. The other end of the bellows is clamped between two rings 35, 36 tightened against each other. the other by a ring 37 fixed to the middle part 34 by screws 38. A compression seal J seals the system.
  • the elastic metal member 3, 23, 33 in the form of a ring of recessed straight section defined by the profile of a non-rectilinear wall of constant thickness, constituting a bellows when it comprises at least two adjacent folds forming a meander ( figure 7 ).
  • Our goal is to be able to obtain a self-guided metal organ, ie not susceptible to flaming or deforming, integrable to a watch box and which has a stiffness adapted to the desired function.
  • stiffnesses are defined by k, their index gives the vertical direction v, horizontal h or tilting 6. Stiffness according to e according to a according to p Vertical and tilting k v ⁇ k b ⁇ e 3 k v ⁇ k b ⁇ 1 at 5 / 2 k v ⁇ k b ⁇ 1 p 1 / 5 horizontal h k, ⁇ e 3/2 k h ⁇ 1 at k h ⁇ 1 p 2 / 5
  • n 0.5
  • guaranteeing the autoguiding of the system is equivalent to minimizing n and p for values of e and a linked to a stiffness defined by the physical function of the bellows.
