Definitions

  • the present invention relates to timepieces comprising a case made at least partially of a hard natural mineral material such as granite and its semi-precious stones, or artificial, such as carbides or nitrides of certain metals such as tungsten or titanium.
  • the time-setting rod which comprises a tube driven radially in leaktight manner in the plate of the movement and crossed by the time-setting rod.
  • the latter receives at its outer end the crown which, in turn, is sealed on the end of the tube by a sealing gasket trapped between an annular rim of the crown and the outer surface of the rod.
  • the box is made at least partially of a hard material, that is to say most often has an outer middle made of this material (in order to make the box resistant to wear)
  • provision must be made, at the point of crossing the tube through this middle part, a clearance opening downwards and extending to the top of the tube. This clearance is necessary to allow the establishment of the movement fitted with its tube.
  • the object of the invention is to provide a watch fitted with a mounting device of the type described above, but which is free from these drawbacks.
  • the subject of the invention is therefore a watch the case of which is at least partially made of a hard material, this case being of the type comprising an outer case made from hard material and an inner case made of a rigid material, but easily machinable, said inner middle part comprising a radial hole for passage of the rod in which the latter is adjusted and engaged in a leaktight manner using a seal fitted in a peripheral groove of the rod and applied against the wall of the hole, characterized in that the outer case is made in one piece with a central veil acting as a dial and has a radial hole aligned with the hole in the inner case and through which the time-setting rod passes freely outside, the diameter of this radial hole being greater than that of the rod, in the part of the latter corresponding to this hole.
  • the outer middle part of hard material has a radial hole which, admittedly, weakens the middle part at this point, but to a much lesser extent than if a clearance opening downwards was practiced.
  • the middle designed according to the invention there remains material all around the passage of the rod, which leads to less brittleness both during manufacture (fewer discarded parts) than during wear (better resistance shock).
  • This advantage is particularly significant when the outer middle part is machined from a block of hard material, such as natural stone or a monocrystalline oxide.
  • the seal being placed on the stem it is possible to produce a crown entirely made of the same material as the outer middle part.
  • the timepiece according to the invention comprises a box 1 comprising a piece 2 made of a natural or artificial hard material such as granite, a semi-precious stone, a metal carbide , a monocrystalline metal oxide or the like.
  • This piece which is in one piece comprises a ring forming an outer middle part 3 of the box and a veil 4 which closes the ring approximately three-quarters of its height, this veil forming the dial 5 of the piece of watchmaking on its upper side.
  • room 2 defines a dwelling circular central 6 which is here coaxial with the external shape of the middle part 3.
  • the latter has a semi-toroidal periphery.
  • the shape of the middle part 3 and the location of the housing 6 are not decisive and are only controlled by the aesthetics which one wishes to give to the timepiece, the housing 6 being able to be off-center. compared to the general shape of the middle part 3 in stone which, itself, can take on extremely varied external shapes also determined by the aesthetics.
  • the face of the web 4 forming the dial 5 is concave while it is bordered by a raised peripheral portion 7 of the outer middle part 3.
  • This portion 7 defines, by its shape, means 8 for positioning and fixing a glass 9.
  • these means comprise an annular step 10 delimiting a shoulder 11 to which the glass 9 can be applied by means of an adhesive joint.
  • the glass 9 is therefore embedded in the height of the outer middle part.
  • the veil 4 is pierced in its center with a hole 12 for the passage of the needles axes 13 and 14.
  • its central zone includes a stiffening portion 15 to stiffen the veil at this location. This stiffening portion is obtained by extending, at the end of machining of the housing 6, the machining operation only on the periphery of the bottom thereof.
  • a metal inner middle part 16 is disposed in the housing 6.
  • This middle part has an annular ring 17a from which the flange 17b extends inwards and it is glued to the outer middle part 2 by adhesive joints interposed between the walls. respective outer and inner peripherals of the middle and also (although this is not essential) between the upper end face of the inner middle 16 and the corresponding lower surface portion of the web 4.
  • the inner middle part 16 is first of all intended to receive the movement 18 of the timepiece via a casing ring 19.
  • the movement 18 is assumed to be of the type in barrel, the casing circle 19 thus having no constant radial section over its entire periphery, which can be seen on the left and on the right in the figure.
  • the casing circle has a shoulder 20 cooperating with a flange practiced in a conventional manner around the periphery of the movement.
  • An annular groove 21 is formed in the underside of the inner middle part to receive a gasket 22. Furthermore, several tapped holes 23 are provided in the middle part to allow its assembly with a bottom 24, by means of screw 25.
  • the bottom 24 is formed by a circular plate whose shape is adapted to the aesthetics of the assembly and which adjusts almost entirely in the opening of the housing 6. This plate carries horns 26 at noon and at six hours, intended to fix a bracelet not shown in the drawing.
  • the timepiece requires for its sealing only a seal at the bottom acting effectively in contact with the metal, the lining being furthermore trapped on all sides by the rectangular section delimited by the bottom and the groove 21.
  • the inner middle part 16 has an outside diameter d 1 greater than the diameter d 2 of the crystal. This choice is deliberate in order to give the inner middle part 16 the role of supporting the fragile zone located at the junction between the veil 4 and the outer middle part 3. In the event of an impact on the wearer, the risks of rupture at this point are thus notably reduced.
  • the passage for the time-setting rod 27 passes through a radial hole 28 drilled in the outer middle part 3 as well as a radial hole 29 made in the inner middle part 16, the latter being adjusted to the diameter of the rod 27 to allow rotation while ensuring its guidance.
  • the rod 27 itself is provided with a groove 30 which is situated approximately halfway in the radial hole 29 and which is intended to receive a seal 31. It is therefore again an active seal against metal surfaces which here assumes watertightness towards the outside.
  • a crown 32 made of the same material as the part 2 can cover the outer end of the rod 27 while being retained thereon by gluing, for example.
  • the hole made in the inner middle part 16 for the passage of the rod 27 is almost tangent to the radial plane containing the upper face of the movement 18. This is due to the fact that the rod 27 must have a comparatively large diameter to allow 'arrange the groove 30 therefor for the joint 31. If the underside of the web 4 was flat, it would result that the thickness of material between the hole 29 and the upper face of the inner middle part 16 would be very small, which could lead to the ovalization of the hole 27 which consequently could not guarantee good contact with the seal 31, resulting in a loss of tightness.
  • the housing 6 has in the periphery of its bottom, a groove which surrounds the stiffening 15 and which allows the use of a thicker inner middle 16, it is possible to guarantee the water resistance of the watch without increasing it thickness.
  • the machining of the part 2 made of hard material is preferably carried out using a process abrasion to your diamond wheel known to specialists.
  • this machining does not require any precision thanks to the presence of the inner middle part which is here the element of the timepiece ensuring all the positioning functions requiring precision, among which may be mentioned positioning the movement, tightening the seals 22 and 31 and positioning the screws 25 with respect to the bottom.
