Definitions

  • the present invention relates to a timepiece, in particular a pocket watch, equipped with at least one cover which, for example, hides a dial above which a set of hands moves.
  • Pocket watch type timepieces were the first timepieces that could be used by people.
  • These pocket watches conventionally include a watch case inside which is housed a clockwork movement which drives a set of hour and minute hands which move above a dial.
  • the hour and minute hands are conventionally covered by a watch crystal.
  • some of these pocket watches are equipped with a movable cover between a closed position in which the cover covers the glass, and an open position in which the cover reveals the dial and hands in the eyes of the owner.
  • pocket watches that come with a top cover and a bottom cover.
  • the top cover covers, for example, a first dial and a first set of hour and minute hands which provide an indication of the current time, and the bottom cover covers a second dial above which a second set moves. hour and minute hands which provide an indication of a second time zone different from that provided by the first set of hands.
  • the second cover can cover a mirror protecting a decorative motif, a family photograph or the like.
  • One of these pocket watches comprises two covers, respectively from above and below, and is equipped with a pendant ring which, in the rest position, extends vertically in the plane of the face of the watch case. .
  • These covers are opened by tilting the pendant ring forward or backward from the plane of the watch case face, and the choice of top or bottom cover to open is made by the direction of the watch case. tilting of said pendant ring.
  • the tilting of the pendant ring in front of the plane of the face of the watch case causes the top cover to open, while the tilting of this same pendant ring behind the plane of the watch face.
  • the watch case opens the bottom cover.
  • the pocket watch comprises two springs which are arranged to open and maintain in the closed position the top and bottom covers respectively.
  • Two pistons are supported on the top of the free ends of the springs.
  • the pendant ring has two cam tracks which are arranged so that, when the pendant ring is tilted forwards or backwards, these cam tracks alternately actuate one of the two pistons, the actuated piston pressing on the corresponding spring, thus unlocking the chosen cover.
  • the mechanism for opening the lids of a pocket watch briefly described above is a very rudimentary mechanism, the main drawback of which is that a simple tilting of the pendant ring forwards or backwards causes immediate opening of the corresponding cover.
  • the risks of unexpected opening of one or the other of these covers are therefore very high, which can be accepted for a cheap pocket watch, but certainly not for a high pocket watch
  • There are still cover opening systems such as the document CH689338A5 , which proposes manipulation of the pendant requiring first a translation of the mobile pendant, then a limited rotation of the latter.
