Definitions

  • the present invention relates to the field of bracelets, especially for watches. It relates to a clasp for bracelets to adjust the length of the bracelet.
  • the invention also relates to a length adjustment device and a wristwatch having the clasp and / or the length adjustment device.
  • a clasp for wristwatches generally comprises two fasteners for attaching the free ends of the wristband, and a locking or closing mechanism for locking the two fasteners, and thus the free ends of the wristband, in a stable position of closure. or lock. This position is also the service position, as it allows the wristwatch to be worn on the wrist.
  • clasps for example the buckle or buckle clasp fasteners, whose aesthetic is well appreciated.
  • the clasps or bracelets for wristwatches generally include means for adjusting the length of the wristband.
  • the free end of one of the two strands of the bracelet comprises a series of holes distributed in the longitudinal direction of the bracelet.
  • the free end of the other bracelet strand is provided with a connecting device, for example a pin buckle, for joining the two strands by inserting the barb in the hole corresponding to the desired length.
  • the length of the bracelet is adjusted by removing or adding a link in one or both strands of the bracelet.
  • the fine length adjustment is generally designed to allow the length of the bracelet to be adjusted to a maximum distance that is defined by the coarse length adjustment mechanism. Depending on the type of clasp this distance may correspond to the size of the links, or to the distance between the holes in the bracelet strand.
  • the fine adjustment device is preferably arranged so as to allow the adjustment of length with a precision defined by the discrete distances of the notch of the fine adjustment over the whole of the adjustable distance of the bracelet. In practice, fine tuning can often be done along a total distance of 3 to 10 mm, at intervals of 1 to 2.5 mm, for example.
  • the fine adjustment device of a bracelet clasp generally comprises a movable part arranged on a part of the clasp and carrying one of the two fasteners, the other fastener being attached to another part of the clasp.
  • the fine adjustment can be made by moving the moving part relative to the whole clasp, and blocking it to the position corresponding to the desired strap length.
  • the fine adjustment device includes a notching or toothing, which defines the discrete positions of length of the fine adjustment.
  • the notching may also be part of the mechanism for locking the moving part in a position of desired length.

  • the clasp comprises a pull tab arranged to cooperate with the carriage and capable of occupying two axial positions so that the carriage is locked and unlocked when the pull tab is respectively in one and the other of the two axial positions.
  • a disadvantage of this mechanism is the fact that at least one of the two opposite pushers of the pull tab is projecting relative to the side walls of the clasp blade. The protruding pusher is likely to cling to an external object, for example a garment.
  • CH 705 149 discloses a clasp type unfolding three blades, the two inner blades each carrying a length adjustment mechanism. To adjust the length, it is necessary to unlock and open the clasp. The length can not be adjusted when the clasp is closed. This is also the case of the clasp disclosed in EP0819391 .
  • This clasp comprises a pivotable adjustment link and a link articulated to the adjusting link.
  • the bracelet length may be adjustable independently of the closed or open condition of the clasp.
  • Another objective is to provide a clasp that is completely separate and independent of the closure mechanism of the clasp, or a length adjustment device that can be associated with any type of clasp, whether it is a clasp with a folding clasp, a clasp with buckle, or other type of bracelet clasp.
  • An object of the invention is also to implement a clasp having a general aesthetic appearance.
  • a clasp whose adjustment mechanism remains discreet and fits into the general shape of the clasp may be desirable.
  • the present invention relates to a clasp, in particular a clasp for a bracelet.
