  • a control member comprising in particular a pusher makes it possible to actuate the trigger to release the hook and open the clasp.
  • Adjusting devices comprising a specific locking member have also been proposed, as an alternative, to avoid this type of drawback.
  • a main object of the present invention is to overcome the drawbacks of clasps known from the prior art, by proposing a bracelet clasp comprising a device for adjusting the useful length of the bracelet of simple structure, preferably proposing stable adjustment, including when the clasp is open, and easy to handle.
  • the present invention relates more particularly to a bracelet clasp comprising first and second blades hinged relative to each other, by a first of their respective ends, between a closed position, to wear, and at least an open position, said first slat carrying a member for fixing a first bracelet strand, said second lower slat being connected to a loop at its second end, the loop defining a passage for a second bracelet strand and carrying a stud intended to be inserted into a suitable hole in the bracelet strand to define an anchoring point of the latter to the clasp, the clasp further comprising at least one locking member for holding said first and second blades in their closed position.
  • a carriage connected to the second end of the second blade, said carriage being arranged to slide in the loop and able to pass from a first indexed position to a second position indexed to define at least two predefined positions associated with a predefined useful length of the bracelet.
  • the invention also relates to a wristwatch comprising a bracelet provided with a clasp according to the invention.
  • clasp 100 is of the folding clasp type and is intended to close a timepiece bracelet.
  • the clasp 100 comprises a first blade 1 articulated on a second blade.
  • Each of the blades has an elongated shape in the longitudinal direction of the bracelet and slightly curved to better match the shape of the wearer's wrist.
  • the first blade 1 comprises two uprights 10 arranged in contact with each other at one of their ends and, each having a cutout such that they are not in contact with each other over the greater part of their length.
  • Each of the uprights 10 carries an extension 11, close to its other end, extending in a direction perpendicular to the longitudinal direction of the bracelet, to form a pusher defining a control member making it possible to unlock the clasp, as is apparent from there figure 1 .
  • the free end of the first blade 1 carries means for holding the bracelet intended to be associated with the clasp 100.
  • the holding means comprise a cover 12 having an upper wall 13 bearing side walls 14.
  • the side walls 14 are provided with two holes 8 making it possible to accommodate one end of a bar for fixing a bracelet strand, in a conventional manner. .
  • the second blade 2 comprises two arms 20 connected on the one hand to the first blade 1, and on the other hand to a loop 3 via a carriage 4.
  • the loop 3 comprises bent portions 30 for the passage of a bracelet strand , offset from the general direction of the arms 20 to define a passage for the bracelet strand.
  • the loop 3 has a first stud 7 and a second stud 31, both intended to be engaged in a different hole in the bracelet to define a first and a second point of anchoring of the bracelet strand to the clasp 100 and thus maintain it well aligned with the clasp.
  • the loop 3 arranged at the end of the second blade 2 carries a device for adjusting the useful length of the bracelet intended to be associated with the clasp.
  • the device for adjusting the useful length of the bracelet comprises in particular the carriage 4 which is provided with a base 40 of rectangular shape and two uprights 41, and which is arranged to move in the loop 3 in the direction of the length of the clasp.
  • the uprights 41 are arranged to slide in corresponding guide grooves 33 provided on the side edges of the loop 3.
  • the carriage 4 comprises an oblong hole 42 formed on the base 40, the oblong hole 42 cooperating with a pin 32 integral with the loop 3.
  • the pin 32 passes through the oblong hole when the carriage 4 is mounted in the passing 3, the uprights 41 being housed in the grooves 33.
  • the oblong hole 42 and the pin 32 make it possible to define the length of the travel of the carriage 4 by relative to loop 3, the ends of oblong hole 42 thus defining the extreme positions of carriage 4.
  • the loop 3 comprises indexing means defining at least first and second indexed positions, these positions making it possible to adjust the comfort of the clasp.
  • the indexing means comprise at least two notches 34 arranged on at least one of the guide grooves 33 to form said at least first and second indexed positions.
  • the loop 3 also comprises a control member arranged to allow the movement of the carriage from one position to another, the control member being in the form of a pusher 5 arranged on the carriage 3 and moving with the latter .
  • the pusher 5 comprises on its upper face a lug 50 arranged to cooperate with the notches 34 of the groove 33 so as to lock the chosen position, namely the first or the second position in the example illustrated.
  • the pusher 5 extends over a large part of the width of the carriage 4 and has a flat portion 51 directly after the lug 50 and being housed in one of the uprights 41 of the carriage 4. Such an arrangement makes it possible to prevent the pusher is dislodged from the carriage 4 during its handling.
  • the pusher 5 is arranged to translate in a direction perpendicular to the direction of the length of the clasp, that is to say in a direction perpendicular to the movement of the carriage 4, and has on its upper face a textured portion to facilitate the gripping the pusher 5.
  • the carriage 4 comprises return means, in the form of a leaf spring 6, arranged to maintain the control member under stress.
  • return means in the form of a leaf spring 6, arranged to maintain the control member under stress.
