Definitions

  • Control device with disengageable crown for watch
  • the present invention relates to a control device with a disengageable crown for a watch, more particularly a control device in which the engagement / disengagement of the crown takes place outside the movement.
  • Known disengageable crowns known as “screwed”, can occupy a engaged position in which the crown is engaged with a drive rod outside the movement and a disengaged position in which the crown is uncoupled from this rod. training.
  • the passage from one position to the other of the crown is obtained by screwing / unscrewing the crown in a crown tube. This is inconvenient for the user.
  • the threads of the crown and the tube tend to be damaged, especially at their entry, which may require replacement of these crown and tube.
  • a device 1 for controlling a watertight disengageable crown comprises a fixed support tube 10 driven into a bore 2 formed in the body (middle part) 3 of a watch case, an axis drive 11 disposed in the fixed tube 10 and integral with a drive rod 4 of the watch, and a crown 12 composed of a head crown 13 and a tube 14 integral with the head 13 and mounted movable in rotation and in translation between the internal wall 10 'of the fixed tube 10 and the drive shaft 11.
  • the drive shaft 11 has teeth external 15 and the movable tube 14 a corresponding internal toothing 16.
  • An annular groove 17 formed in the internal face 10 ′ of the fixed tube 10 constitutes a housing for an O-ring seal 18.
  • the external face of the mobile tube 14 has two formations , in this case first and second annular grooves 19, 20, able to cooperate with the seal 18 to define two stable axial positions for the crown 12.
  • first and second annular grooves 19, 20, able to cooperate with the seal 18 to define two stable axial positions for the crown 12.
  • the teeth 15, 16 are in engagement allowing the drive shaft 11 and therefore the drive rod 4 to rotate when the crown 12 is turned by the user.
  • This open position is a service position, in which the rotation of the crown 12 controls a specific function in the watch, such as the rotation of the city disc for displaying the time zone or any other similar function.
  • the teeth 15, 16 are not engaged so that the crown 1 can rotate freely without driving the axis 11.
  • This closed position is a rest position of the mechanism, in which no particular function of the watch is controlled when the crown 12 is turned by the user.
  • Two stops 21, 22 consisting, for the first, in a flange extending around the drive axis 11, and for the second, in the head of a screw screwed into the end of the axis 11 the further from the watch case, limit the axial displacement of the crown 12 respectively in the direction tending to bring the crown 1 closer to the watch case and in the opposite direction tending to move the crown 12 away from the watch case.
  • seals 23, 24 disposed between the bottom of the fixed tube 10 and the flange 21 provide sealing between the fixed tube 10 and the drive shaft 11.
  • the axis 11 is slid into the tube 14 then the stop screw is screwed into the axis 11. Then, the assembly 11, 14 is driven out and welded in the crown head 13 2.
  • the two seals 23, 24 are slid into the bottom of the tube 10 and the indexing O-ring 18 is positioned in the groove 17 of the tube 10. 3.
  • the assembly 11, 13, 14 is mounted in the tube 10 and the drive rod 4 is screwed and glued in the axis 11. 4. The whole is driven into the middle part 3 of the watch.
  • the present invention is not limited to the embodiment described above. It will be clear to those skilled in the art that modifications can be made without departing from the scope of the claimed invention.
  • the fixed tube 10 could be omitted and the annular groove 17 receiving the indexing seal 18 formed directly in the bore 2 of the middle part 3.
  • the relative position of the grooves 19, 20 and the groove 17 could be reversed, that is to say that one could form the grooves 19, 20 in the internal face 10 ′ of the fixed tube 10 and the groove 17 receiving the indexing seal 18 in the external face of the movable tube 14
  • Another modification could consist in adding one or more additional axial positions for the crown 12, indexed either in the device according to the invention by one or more additional annular grooves on the movable tube 14 or in a conventional manner inside the movement. of the watch, to allow control of other functions in the watch, such as winding, setting the time, etc.
