Definitions

  • the present invention relates to watches whose box forms platinum. It relates more particularly to a platinum alloy or metallic compound box.
  • the object of the present invention is to provide a watch whose platinum-shaped case, the manufacture of which is simplified and which is capable of presenting aesthetic effects that are both varied and original.
  • the watch case according to the invention consists of a stack of plates, the two ends of which respectively form the bottom of the case and the bezel carrying the crystal and the others of which are cut so as to form housings. in which the watch components are attached individually.
  • FIGS. 1a and 1b a watch according to the invention is shown diagrammatically, with its case 10, a control rod 12, a dial 14 and hands 16.
  • the box 10 is formed by a stack of 12 plates, numbered from 20 to 31, which are shown separately in FIG. 2. They have roughly the shape of hexagons and their external dimensions are chosen so as to obtain a middle profile. stepped, as it appears in Figures la and lb.
  • the upper plate 20, which forms the bezel, has a central opening 32, of circular shape, closed by a crystal 33.
  • the fixing of the latter is advantageously carried out by gluing.
  • the plate 20 may itself be transparent and also act as ice.
  • the lower plate 31, which constitutes the bottom of the box, is pierced with a circular opening 34 allowing the passage of a stack. This opening closes with a hatch 35 which is, for example, screwed into the plate 31.
  • the plate 24 acts as a dial and therefore carries fixed marks 36 which define the divisions of time. It includes a window 37 allowing the reading of a date disc, as well as a small central hole 38 intended to allow the passage of trees carrying the hands 16.
  • the six plates 25, 26, 27, 28 29 and 30, arranged between the plate 24 and the bottom 31, have openings 42, 43, 44, 45, 46 and 47 respectively, whose shapes are such that they allow define housings for components of the watch movement.
  • the movement essentially comprises an electronic module 48 (FIG. 3), a motor module 49 (FIG. 3), a date module 50 (FIG. 4) and a battery 51.
  • the electronic module 48 (FIG. 3) comprises a printed circuit 52 and, mounted on this circuit, a quartz resonator 53 and an integrated circuit 54. This module takes place in the opening 47 of the plate 30. It rests on the plate bottom 31 to which it is fixed by gluing.
  • the motor module 49 (FIG. 3) is based on a stator 55 on which are mounted a coil 56, a rotor 57 and a gear train 58 driving the hands 16.
  • the latter includes a time setting reference 58a which can be actuated using the control rod 12.
  • This module takes place in the openings 44, 45, 46 and 47 of the plates 27, 28, 29 and 30. It rests on the plate 30 to which it is fixed by two nails 59 which are welded to this plate.
  • the date module 50 (FIG. 4) comprises a date disc 60 and a wheel 61 for driving this disc 60, itself driven by the gear train of the motor module.
  • a bridge 62 carries a jumper spring 63 cooperating with the teeth of the disc 60.
  • Two fingers 64 and 65 carried by the bridge 62, maintain the wheel 61.
  • the spring 63 and the fingers 64 to 68 came in one piece with the bridge 62.
  • the latter carries, finally, a corrective train 69 which kinematically connects the control rod 12 and the date disc 60.
  • the date module takes place in the circular openings 42 and 43 of the plates 25 and 26.
  • the opening 43 has fingers 70 (better visible in FIG. 2) directed towards its center, on which the disc 60 rests.
  • the opening 42 also has fingers 71 which are shorter than fingers 70 and serve to center the disc 60.
  • the bridge 62 is welded to the plate 27 at three points which do not appear in the figures.
  • the stack 51 introduced through the opening 34 of the bottom plate 31, takes place in the openings 45, 46 and 47 of the plates 28, 29 and 30.
  • the three plates 25, 26 and 27 have ears 72 allowing the attachment of a bracelet (not shown).
  • time-setting rod 12 is pivotally mounted in a tube 73 (FIG. 3) which is housed and glued in openings 74, 75, 76 and 77 (FIG. 2) that the plates 26, 27 respectively have, 28 and 29.
  • the rod drives a reference 78 ( Figure 4), mounted on a rocker (not visible in the figures) pivotally mounted on the plate 28.
  • reference 78 is free or meshes either with the date correction cog 69 or with the time setting reference 58a.
  • Stainless steel by its moderate cost, its pleasant appearance, its mechanical and chemical resistance and its machinability, lends itself particularly well to the manufacture of the can described above. Copper or aluminum alloys offer a wide variety of colors thanks to the surface treatments they can undergo. Obtaining particularly resistant boxes is possible by the use of plates of metal compounds such as borides, nitrides, tantalum carbides, titanium, tungsten, vanadium, etc., or oxides such as alumina.
  • the metal plates are preferably cut into strips by means of a progressive stamp which makes the interior openings before cutting the exterior shape.
  • the metal compound plates are produced by sintering, in molds which define the interior and exterior shapes. In both cases, the plates are then subjected to the finishing operations, by grinding, brushing and / or polishing. As the plates are flat, it is possible to automate these operations. Finally, the plates undergo, if necessary, a surface treatment which gives them their final appearance, then they are assembled.
  • the assembly of the watch which has just been described can be carried out in the following manner.
  • the lower plates 25 to 31 are first assembled by gluing.
  • the tube 73 is also glued in its housing.
  • the electronic module 48, the motor module 49, the control rod 12, the lever carrying the reference 78 and finally the date module 50 are then put into place in the plate thus formed.
  • the dial plate 24 is then bonded to the plate 25, then the needles 16 are put in place. It then only remains to close the watch by stacking the plates 20 to 23 on the plate 24.
  • the assembly of these plates is also produced by gluing.
  • the battery 51 is finally introduced into its housing through the opening 34 which is then closed by the hatch 35.
  • the invention makes it possible to reduce the costs of manufacturing watches whose box is made of metal or of metal compound while giving the possibility of creating original box shapes.
