Definitions

  • the present invention relates to watch frame members.
  • the frame consists of a plate and bridges mounted on the plate.
  • the plate and the bridges are made of brass machined by mechanical operations.
  • Such a solution makes it possible to manufacture a frame economically and in satisfactory accuracy.
  • stones are driven into platinum and bridges.
  • the document EP 0131267 describes a watch in which the frame is formed of a stack of plates made, for example, of corundum.
  • the bearings are directly made in the plates.
  • Such plates can advantageously be manufactured by photolithography techniques. This allows a very high precision in the positioning of the holes, as well as a small thickness of the watch.
  • the assembly of plates poses problems that are difficult to overcome. Indeed, plates of hard mineral material such as corundum or silicon are fragile and the risk of rupture during screw tightening can not be excluded. This implies significant additional costs.
  • An object of the present invention is to overcome this disadvantage.
  • the present invention therefore relates to a watch frame member, intended to be mounted on a base defining a reference plane.
  • This member is formed of a plate made of a hard mineral material chosen from diamond, corundum and silicon, characterized in that said member also comprises at least one interposition element arranged on at least one of the faces of the plate, in places under tightening pressures.
  • the assembly shown in the drawing is a cage intended to equip a tourbillon watch movement.
  • the cage includes a plate 10 defining a reference plane AA, pillars 12 and bridges 14 and 16.
  • a gear train 18 and an escapement 20 are pivotally mounted between the plate 10 and the bridges 14 and 16.
  • the pillars 12 are driven into the plate 10. They have bearing surfaces on the bridge 14, the surfaces being parallel to the plane AA. As can be seen more particularly on the figure 2 , the pillars 12 comprise a threaded hole 12a and a bearing 12b.
  • the bridge 14 has holes 14a engaged on the bearing surfaces 12b and resting on the pillars 12. Clamping elements, typically screws 22, are clamped in the holes 12a and bearing against the bridge 14.
  • the plate 10 further comprises two columns 10a also having support surfaces to the bridge 16, the surfaces being parallel to the plane AA.
  • the bridge 16 also has holes 16a engaged on spans 10b whose columns 10a are provided.
  • the plate 10 and the pillars 12 are preferably metal, usually brass.
  • the plate 10 is pierced with holes 10b in which are thrown stones 24 in lieu of bearings to the wheels of the wheel 18 and the exhaust 20.
  • bridges 14 and 16 are made of a hard nonmetallic material, and more particularly of silicon, corundum or diamond. Both of these materials have coefficients of friction with steel of interest, so that it is possible to achieve the bearings of the wheels of the gear train 18 and the exhaust 20. It is thus possible to avoid the addition of stones as explained about the plate 10. In this way, the thickness of the movement can be reduced. Indeed, the bridges can have a thickness of the order of 0.15mm. This is not possible with a brass bridge.
  • each bearing 14 of the bridge may have a cup (30) formed recessed around the bearing.
  • the cup defines an oiler forming a kind of reservoir for a lubricant, in order to improve the pivoting conditions of the mobiles in the silicon.
  • the cup is typically circular in shape and is made by etching.
  • Bridges 14 and 16 are made from silicon, corundum or diamond plates by photolithography techniques. These techniques allow a very high dimensional accuracy.
  • the Deep Reactive-lon Etching (DRIE) deep-reactive ion etching technique is preferably used.
  • the bridges 14 and 16 are coated, on at least one of their two faces, with metal strips identified by the letters b and c , for example nickel, in the vicinity of the holes 14a and 16a, by the technique known as LIGA.
  • This technique makes it possible to deposit layers having a high precision in thickness. In this way, it is possible to achieve a less fragile assembly, while taking advantage of the precision offered by photolithography and LIGA, by interposing metal elements where the screws exert a pressure, so as to avoid direct contact between the plate and the base and / or between the plate and the clamping elements.
  • the position of the bridges 14 and 16 is thus defined, in a plane parallel to the plane AA, by the cooperation of the holes 14a and 16a made in the silicon with the bearing surfaces 12b and 10b.
  • the position of the bridges 14 and 16 is defined, along axes perpendicular to this plane AA, by the support of the metal surfaces 14b, 16b on the pillars 12 or the columns 10a, particularly on their bearing surfaces.
  • the bridge 14, which comprises four holes 14a, is positioned in a plane parallel to the plane AA, only by two holes, the other two being of larger diameter.
  • the holes ensuring positioning in the plane will advantageously be chosen so that the distance between them is as great as possible. It is also possible to realize some of holes of oblong shape, so that small position errors do not generate tensions.
  • the plate 10 is also made of silicon. With this embodiment the total height of the assembly can be further reduced.
  • the plate 10 has holes 10c in which the pillars 12 are engaged. It includes, around these holes, metal layers 10d forming layers deposited by the technique known as LIGA.
  • one of the pillars bearing the reference 12A, provides both positioning in the plane and height, while the second pillar 12B takes the place of wedge and defines the space between the plate 10 and the bridge 14 .
  • the metal layer is limited to the vicinity of the places where screws exert pressure.
  • metal could also be placed in other places, for example to stiffen the plate, without increasing the thickness of the movement.
