This adjustment is generally definitive and does not take into account the differences in the wrist circumference as a function of the ambient heat and / or according to the efforts made by the wearer.
  • the device disclosed in the publication US5927577 comprises a tip whose one end is articulated at one end of one of the strands of the bracelet, the other end of the tip being equipped with a rod susceptible to be positioned inside a lid in different orifices arranged along the lateral sides of the latter.
  • the major disadvantage of this device comes from the fact that it is necessary to open the clasp to adjust the length of the bracelet.
  • JP59108411 relates to a clasp for a two-blade deblocking buckle having a first and a second blade articulated with respect to one another at a first end and a hinged cover at a second end of the first blade, the hood being connected to a first strand of the bracelet.
  • a substantially rectangular opening extends along the longitudinal axis of the second blade. The longitudinal sides of this opening are provided with a notched portion arranged to cooperate with locking means, which are integral with a support of the folding clasp, the support being connected to a second strand of the bracelet.
  • the locking means comprise two locking elements intended to be positioned in one of the notches of each notched portion of the opening of the second blade to lock it with respect to the blade holder in a desired indexed position.
  • the locking means further comprise a pusher whose actuation allows to release each blocking element of the corresponding notched portion in order to adjust the length of the bracelet.
  • Each locking member is then positioned in another one of the notches of the one and the other notched portions when the pusher is no longer actuated to lock the second blade with respect to the blade support in another indexed position.
  • EP1716776 discloses a device for adjusting the length of a bracelet which is intended to remedy in particular the problem referred to above.
  • This device comprises a lid inside which is slidable articulated tip at one end of the bracelet.
  • This tip comprises means for prepositioning and locking in position cooperating with a release system for adjusting the length of the bracelet without having to open said bracelet.
  • this adjustment device is intended to be mounted on rigid bracelets link or the ends are subject to a foldable hinged clasp.
  • This device is not suitable for leather bracelets or other flexible material which one of the strands is intended to be arranged in a passing assembly provided with a pin for a coarse adjustment of the length of the bracelet.
  • the publication EP1378185 proposes a clasp with folding clasp with two blades that solves the aforementioned problems.
  • the two blades of this clasp are articulated with respect to one another at one of their ends while the other of their ends are respectively connected to a cover connected to one of the strands of a bracelet and to a movable tip connected to the other strands of the bracelet.
  • the movable tip is arranged inside a receptacle inside which are mounted indexing means for adjusting the length of the bracelet.
  • These indexing means comprise two locking elements arranged to cooperate each with a notched tooth-shaped portion located along the inner side walls of the receptacle.
  • Two pushers disposed on the outer lateral sides of the receptacle allow, when actuated, to release the locking elements of the notched parts in order to adjust the length of the bracelet.
  • the object of the present invention is to propose a different version of an extensible bracelet clasp which has the advantage of providing precise adjustment of the length of the bracelet when the clasp is in the closed position and which can easily be adapted to be mounted on a link bracelet or to cook.
  • a clasp with a folding clasp for a bracelet enabling the length of the bracelet to be adjusted, and comprising: a first and a second blade articulated with respect to one another at a first end; a first fastener arranged at a second end of the first blade to be connected to a first strand of the bracelet; a second fastener arranged at a second end of the second blade to be connected to a second strand of the bracelet; and indexing means for the second fastener to occupy different indexed positions relative to the end of the second blade.
  • the second clip is connected to a carriage, which is disposed in a housing on the second blade.
  • the housing has two opposite walls along which the carriage is slidable.
  • the clasp further comprises a pull tab connected to the second blade and arranged to cooperate with the carriage, the pull being able to occupy two axial positions so that the carriage is locked and unlocked when the pull is in the one and the other of its two axial positions.
  • FIG. 1 represents an exploded view of the clasp with a folding clasp for a watch strap according to the preferred embodiment of the invention
  • FIG. 2 represents a side view of the clasp in which the fastener intended to be connected to a second strand of the bracelet is in a first indexed position
  • FIG. 3 represents a sectional view of FIG. 2 according to A-A
  • FIG. 4 represents a side view of the locked clasp and wherein said fastener is in a second indexed position

  • the carriage 16 comprises six notched portions 21, ie three lower notched parts (FIGS. 3 and 5) and three upper notched parts (not visible) each comprising a succession of recesses 21 'of a certain radius of curvature.
  • Four of the six toothed portions 21 are located along the sides of the carriage 16 which face the walls 18, 18 'of the housing 17. More specifically, in view of FIG. 3, each lateral side of the carriage 16 has two notched portions 21a. , 21 b which are arranged facing one part compared to the other. The two notched portions 21 remaining are facing one part relative to the other at the middle portion of the carriage 16 in the axis of its displacement.
