Definitions

  • the present invention relates to a method for opening a watch case by extracting the ice.
  • the movement can only be assembled from the top of the middle, after which the glass is tightly placed, for example by means of a seal interposed between the edge of the crystal and the inner edge of the middle or of the bezel.
  • This procedure is generally reserved for mineral ice or sapphires. If we have to repair the movement, we have no other resource than to extract the ice from its seat after which the movement can be taken out of the box.
  • the method according to the invention is characterized in that it comprises the succession of the following stages: the box is fixed in an enclosure, a suction cup is applied to the glass, the interior of the enclosure is subjected just as the interior of the box at the same determined overpressure, exerts a pulling force on the suction cup until the ice is extracted, and restores the normal pressure in the enclosure to take out the box stripped of its ice.
  • an apparatus characterized in that it comprises a frame in which is housed a pump, an enclosure surmounting the frame and in which opens a conduit communicating with the pump, the enclosure comprising a device for fixing the watch case, said enclosure being surmounted by a removable cover closing off its upper part, said cover being provided with a valve and a rod, the latter being slidably mounted through the cover and bearing , to his end located in the enclosure, a suction cup capable of being applied against the ice to be extracted from the box.
  • the watch case 1 is fixed in an enclosure 3.
  • a suction cup is applied 4.
  • the interior 5 of the enclosure and the interior of the watch are both subjected to the same overpressure. determined, which will have the effect of applying the suction cup to the ice with a force proportional to the overpressure prevailing in the enclosure.
  • a traction force A is exerted on the suction cup until the ice is extracted.
  • FIGS. 1 and 2 describe a specific device making it possible to implement this process.
  • the apparatus comprises a frame 14 in which there is a pump (not shown), a pump actuated by a lever 37.
  • a cylindrical enclosure 3 surmounts the frame 14 to which it is fixed by means of two tie rods 39. This enclosure is located under the form of a transparent tube into which a conduit 15 which communicates with the pump opens.
  • the upper part 41 of the enclosure 3 is closed by a removable cover 17. This cover is fixed to the enclosure by means of two chickens 33. The seal between the upper part 41 of the enclosure and the cover 17 is ensured by an O-ring 31.
  • the cover 17 is provided with a valve 18 to let out the overpressure air when it is pressed on its rod.
  • the cover is crossed by a rod 19 slidably mounted in the center of the cover, another O-ring lining 32 ensuring the seal of the rod.
  • One end of the rod 19 is provided with an operating handle 40, while the other end, that located inside the enclosure, is equipped with a suction cup 4 capable of being applied against the ice 2 which is to be extracted from watch case 1.
  • FIG. device 16 first comprises a cylindrical block 27 having a channel 35 to allow the conduit 15 to pass and four threaded rods 30, screwed into the block 27 and extending to the cover 17. On this block 27 the box 1 is placed , bottom against the block.
  • the device 16 also includes a ring 28, the central opening 36 of which has a diameter slightly larger than the diameter of the crystal 2. This ring also includes a channel 34 for letting the conduit pass. 15 and four holes which allow the ring to be threaded into the threaded rods 30.
  • FIG. 3 shows a box 1 having a middle part 7 made in one piece with the bottom 8.
  • the movement 11 comprises a crown 10 with a broken rod 9 which can be separated from the part 42 adjoining the movement.
  • the interior space 6 will be connected by the tube 43 to the exterior space 5 prevailing in the enclosure 3.
  • the base 8 is placed on the block 27 and the middle part 7 is retained by the ring 28.
  • the suction cup 4 is applied to the crystal 2 then the pressure in the enclosure is increased to a determined value from which a force can be exerted pulling on the suction cup to extract the ice.
  • FIG. 4 shows a case 1 which has a bottom 12 separate from the middle part 13, but where the movement 11 can only be taken out from the middle part from above.
  • the first suction cup 4 which comes to mind to tear off the ice is the conical suction cup 20 shown in FIG. 2.
  • This suction cup is retained at the end of the rod 19 by means of the screw 24.
  • the suction cup shown in detail in FIG. 5 it is preferable to use the suction cup shown in detail in FIG. 5.
  • the suction cup of Figure 5 essentially comprises an O-ring 21 which is applied against the glass 2 to be extracted.
  • the seal 21 is trapped between two circular elements 22 and 23 and retained by circular claws 25 and 26.
  • the elements 22 and 23 are fixed to the rod 19 by means of a screw 24.
  • the seal 21 can be of well-controlled quality and is securely attached to the rod 19. A hardness of the order of 70 shores for the joint gives good results.
  • the extraction force In the case of an overpressure of 4 bars and a suction cup diameter of 15 mm, the extraction force will be 70.7 N. By increasing the overpressure to 6 bars, the extraction force will be 106 N At an atmospheric pressure of 1 bar and with the same 15 mm suction cup, the extraction force is only 17.6 N, a force which is incapable of extracting the ice from its housing.
  • the apparatus shown in perspective in FIG. 1 is identical to apparatus No. 5555 supplied by the company Bergeon & Cie SA, CH-2400 Le Locle, except as regards the setting 16 and the suction cup 4 which have been added to it.
  • the device No 5555 is used for the water resistance test of watches. We see that by providing it with a removable fitting 16 and a new cover 17 fitted with a suction cup 4, the basic device can be used to fulfill a new function, the old function can be found very quickly if necessary.
