Definitions

  • the present invention relates to a method of mounting a screwed crown, such as a winding crown, on a watch case.
  • the invention relates to such a mounting method for indexing the position of a screwed crown on a watch case so that a logo affixed to the face of said crown is always easily returned to a position or orientation determined after have been unscrewed.
  • the patent CH 662 697 discloses a watch case comprising a passage for the rod of a manual movement control mechanism passing through a box tube screwed into the body thereof.
  • the tube has, externally, a shoulder having a frustoconical bearing surface annularly supported on the box body in order to prevent untimely loosening of the tube.
  • the patent CH347 136 discloses a winding crown comprising a core for receiving the winding stem.
  • a plate rests on the upper face of the core and a sleeve surrounds the core and closes against it the wafer, may carry an inscription, for example a trademark or trade.
  • the main object of the present invention is to overcome the drawbacks of the abovementioned prior art by providing a simple and economical method for mounting a crown comprising a logo or a mark which systematically allows the crown to be screwed back into a position where orientation determined after being unscrewed.
  • the invention also relates to a watch case comprising a screwed crown provided with an internal thread, the front face of said crown comprising a logo or a mark, an intermediate tube comprising a threaded outer portion for receiving said tapping, said intermediate tube being fixedly mounted in the box, the latter being characterized in that the inner thread of the ring is indexed relative to the logo or to the mark and in that the intermediate tube is mounted in the box in order to be angularly oriented relative to the box and fixed on the box in a determined angular position
  • the ring comprises on the opposite side to said front face an annular groove in which is fixedly mounted a ring provided with an internal thread.
  • the ring is welded to the ring.
  • the intermediate tube is mounted in a smooth hole in the box and is secured to the box by means of a nut.
  • the screwed crown 1 comprises a first portion formed of a head 3 having a front face 4 on which is affixed a logo or a mark 5 which, in the screwed position of this ring, has a defined angular orientation with respect to the box 2 This first part is connected to the movement in a conventional manner.
  • the head 3 is provided on the opposite side to the end face 4 of an annular groove 7 which receives a ring 8 internally threaded 9.
  • the ring 8 is positioned in the groove 7 with the help of a template (not shown) in a way to indexing said tapping 9 relative to the logo 5 and is immobilized in the groove 7 in said indexed position.
  • the indexing operation is preferably performed using a camera and the immobilization is performed by a welding operation for example a laser welding.
  • the logo 5 therefore has a determined angular position and is known with respect to the entry of the tapping 9.
  • the ring further comprises a second part connected to the box 2. This second part comprises an intermediate tube 10 and a nut 11 intended to immobilize the tube 10 in a defined angular position on the box 2.
  • the tube 10 comprises two externally threaded sections 12 and 13 which cooperate respectively with the nut 11 and the indexed tapping 9.
  • the tube 10 is freely mounted in a through hole 14 smooth of the box.
  • the tube 10 is then wedged using a template (not shown) to arrange the inlet of the thread 13 in an angular position such that when the ring 1 is screwed in abutment on the tube 10, said logo 5 is located in an angular position determined with respect to the box.
  • the crown can be already screwed fully on the tube 10 during its positioning, the indexing was then not on the entry of the thread 13 but directly on the orientation of the logo before the locking of the tube 10 to using the nut 11.
