Definitions

  • the present invention relates to the field of bracelets, in particular for watches. It concerns a clasp for a bracelet allowing the length of the bracelet to be adjusted.
  • the invention also relates to a length adjustment device and a wristwatch, not claimed, comprising the clasp and/or the length adjustment device.
  • a wristwatch clasp generally comprises two fastening members for attaching the free ends of the bracelet, and a locking or closing mechanism for locking the two fastening members, and thus the free ends of the bracelet, in a stable closed position or locking. This position also constitutes the service position, since it allows the wristwatch to be worn on the wrist.
  • clasps for example the pin buckle or the folding clasps, whose aesthetics are well appreciated.
  • Clasps and bracelets for wristwatches generally include means for adjusting the length of the bracelet.
  • 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 strand of the bracelet is provided with a connection device, for example a pin buckle, making it possible to join the two strands by inserting the pin into the hole corresponding to the desired length.
  • a connection device for example a pin buckle
  • Wrist size varies greatly from wearer to wearer.
  • the size of a wearer's wrist may vary with changes in temperature. The same wearer may therefore wish to regularly finely adjust the length of the bracelet to be perfectly comfortable.
  • the state of the art knows clasps for wristwatches which allow fine adjustment of the length of the bracelet. This is a mechanism arranged to allow modification of the circumference defined by the case of the watch, the bracelet, and the clasp, when the clasp is closed, in order to adapt this circumference to the size of the wrist of an individual wearer. This modification takes place on a smaller scale than that defined by the spacing of the holes in a strand of leather bracelet or by the links of a metal bracelet, for example. Fine adjustment is desirable to precisely adapt the aforementioned circumference to the wrist of each wearer.
  • the fine adjustment device of a clasp for a bracelet comprises a moving part arranged on a part of the clasp and carrying one of the two fixing members, the other fixing member being attached to another part of the clasp .
  • the fine adjustment can be made by moving the moving part relative to the clasp assembly, and locking it in the position corresponding to the desired bracelet length.
  • the fine adjustment device includes a notch or toothing, which defines the discrete length positions of the fine adjustment.
  • the notching can also be part of the device making it possible to block the moving part in a position of desired length.
  • the document CH 704 335 discloses a folding clasp, in which a fastening member is attached to a carriage arranged to slide in a housing arranged on a blade of the clasp.
  • 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 or 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 blade of the clasp. The projecting pusher is likely to catch on an external object, for example on a piece of clothing.
  • the bracelet length can be adjusted independently of the state - closed or open - of the clasp.
  • an objective of the present invention is to reduce the thickness, that is to say the extension of the clasp in the radial direction with respect to the axis of the wrist of a wearer.
  • Another object of the invention is to reduce the weight of the clasp, for example to reduce the quantity of metal used in the manufacture and to make the clasp easier to wear.
  • the fine adjustment device is arranged in a yoke or an upper cover, which contributes to the increase in thickness and to the overall size of the clasp.

  • the movable part is arranged at one end of a blade of the clasp so as to extend beyond the end of the blade when the bracelet is lengthened. In this case, the movable part becomes visible as an extension of the clasp.
  • An object of the invention is to provide a clasp making it possible to adjust the length without this changing the appearance of the clasp from the outside.
  • a clasp whose adjustment mechanism remains discreet and integrates into the general shape of the clasp may be desirable.
  • one objective is to avoid the presence of notches visible from the outside or else of longitudinal openings arranged along a side wall of a clevis of a clasp with a folding clasp.
  • An object of the present invention is to present a clasp making it possible to activate the length adjustment when the clasp is closed, and this preferably without a dedicated and separate actuating member, such as a pusher, a pull tab or yet a slider is visible from the outside when the clasp is closed.
