Definitions

  • the invention relates to a bracelet clasp, and in particular to watch bracelets.
  • a folding clasp comprising a rigid base provided with two side members, a yoke arranged to be attached to a strand of the bracelet, and at least one folding arm having a rear end attached to one end of the base by a first articulation and having a front end attached to the yoke by a second articulation.
  • the folding arm comprises two juxtaposed branches provided with pushers, and the front ends of which are separated by an elastic element.
  • An aim of the present invention is to overcome all or part of the drawbacks mentioned above by providing a clasp which meets the security constraints while allowing symmetrical opening of the latter.
  • the invention also aims to provide a clasp of simple design and economical to manufacture.
  • such a bracelet clasp makes it possible to limit the travel of each flexible branch and therefore to guarantee the function of the clasp by a symmetrical opening of the branches.
  • the invention also relates to a wristwatch comprising a bracelet provided with a clasp according to the invention.
  • THE figures 1 And 4 are perspective views of the bracelet clasp which comprises a first rigid blade 1 having two longitudinal members 1a and 1b connected to each other by a bridge 1c. A first end 10 of this blade is articulated to a first end 20 of a second folding blade 2 by means of a shaft 12. This second blade 2 is configured to receive a first strand of the bracelet at its second end 21 by means of a shaft 23.
  • the first blade 1 can be provided as solid and have a receptacle comprising locking means configured to receive the branches 32 and 33.
  • the clasp also comprises a yoke 4, articulated to the branches 32 and 33, provided with first and second flaps 40 and 41 extending perpendicularly to the yoke 4.
  • the flaps 40 and 41 have holes 42 and 43 configured to receive the ends of pushers 320, 330 to provide the articulation between the branches 32, 33 and the yoke 4.
  • the clasp comprises a stop 23 arranged to be housed or rest between the first and second branches 32, 33 of the third blade when the clasp is in the closed position, and more precisely between the ends of the first and second branches 32, 33 which receive the pushers 320, 330.
  • the stop 23 is arranged in the middle of the first blade 1 on the bridge 1c connecting the two side members 1a and 1b.
  • each end of the branches 32, 33 receiving a pusher 320, 330 comes into contact with the stop 23 when pressure is exerted on the pushers 320, 330.
  • the stop 23 thus makes it possible to limit the travel of the free ends of the branches 32 and 33, the distance between the end of the branches 32, 33 and the stop 23 defining the travel length of the free ends of the branches 32 and 33. In this way, it is possible to predetermine the necessary travel length of the branches 32, 33 to obtain a symmetrical movement of the latter and guarantee the correct opening of the clasp.
  • the clasp When pressure is exerted on the pushers 320 and 330, the clasp is unlocked by a symmetrical opening of the branches 32, 33, the stop 23 making it possible to limit the travel of each branch 32, 33 and therefore to guarantee the correct opening of the clasp.
  • the wearer simply exerts simultaneous pressure on the two pushers 320, 330 until the free end of the flexible branches 32, 33 come into contact with the stop 23.
  • the hooks 34 and 35 of the branches 32 and 33 then disengage from the hooks 14 and 15 of the side members 1a and 1b, thus causing the release of the third blade 3 and the opening of the clasp.
