Definitions

  • the invention relates to a system for locking at least one control element of a timepiece. It also relates to a watch case comprising such a system. Finally, it relates to a timepiece, in particular a wristwatch, comprising such a system or such a case.
  • Locking devices are known from the state of the art.
  • a push button capable of being screwed against a ring so as to secure it in position, and thus avoid any untimely activation of a watch function driven by said push button.
  • activation and deactivation devices for a push button as there are push buttons fitted to a timepiece.
  • devices are also proposed allowing, in a single operation, the synchronized activation or deactivation of at least two push buttons. Nevertheless, such devices are not optimal and can in particular compromise the functional or aesthetic integrity of the timepiece.
  • the patent CH423638 relates to a specific construction of waterproof and screwed push button.
  • a threaded and screwed ring on the pusher is capable of occupying two positions, one, of rest, in which it allows said pusher to be actuated, and the other in which it bears on a part of the box of the timepiece, so as to exert an axial traction on the pusher having the effect, on the one hand, of compressing a seal interposed between said pusher and the element of the case through which it passes, and on the other hand to block the pusher.
  • the patent application CH704262 discloses a device allowing the synchronized blocking of a crown and at least one push button. Such a device is controlled by a ring arranged concentrically to said crown. The handling of such a ring can prove tricky, in particular when the latter has to be actuated under water on the occasion, for example, of the practice of scuba diving.
  • the patent application EP2399172 relates to an internal blocking device for push buttons of a wristwatch.
  • the push buttons can be activated or deactivated in a synchronized manner by means of a crown, which is provided for winding and adjusting the wristwatch.
  • the unscrewing/rescrewing of said crown induces the unlocking/locking of the push buttons by means of a mechanism internal to the case.
  • Such a design cannot be suitable with regard to predefined tightness criteria, in particular if the push buttons have to be manipulated in a marine environment.
  • the push buttons can be activated or deactivated in a synchronized manner by means of a rotating bezel.
  • Such a design requires additional seals to allow actuation of the mechanism internal to the box and is therefore not optimal with regard to the aforementioned criteria. Furthermore, such a solution is not optimal for a graduated bezel provided to provide another function or an indication such as time information or information derived from the time.
  • the patent application CH700535 relates to a rotating bezel of asymmetrical geometry which is, for a predefined angular position, designed to hide a crown for winding and/or adjusting a timepiece so as to avoid any inadvertent manipulation.
  • a graduated bezel provided to provide another function or an indication such as time information or information derived from the time.
  • the masked member is not perfectly secure given that it can be inopportunely activated from the “under” side of the watch case.
  • the patent application JP2005337792 relates to a rotating bezel which is provided, in a predefined angular position, to interpose with push buttons so as to block their translation. More particularly, a flank made in one piece with the bezel can be shaped to be housed within grooves formed on each of the push buttons so as to constitute an activation and deactivation device external to the watch case. The state of this device is provided here by markings arranged on the rotating bezel. Such a solution is therefore not optimal for a graduated bezel provided to provide another function or an indication such as time information or information derived from the time.
  • the patent application US20100128575 discloses a device similar to that of the document JP2005337792 .
  • a rotating bezel acts on push buttons via a locking element which is concentric with it.
  • This locking element takes the form of a washer which comprises elastically deformable portions so that they can intervene in the translation of the push buttons.
  • the state of the device is provided by markings arranged on the rotating bezel. Such a solution is therefore not optimal for a graduated telescope intended to provide a other function or an indication such as time or time-derived information.
  • the object of the invention is to provide a locking system making it possible to remedy the aforementioned drawbacks and to improve the locking systems known from the prior art.
  • the invention proposes a locking system that is compact, reliable and has a minimum impact on the aesthetics and functionality of the timepiece.
