Definitions

  • the subject of the present invention is a bracelet clasp with a folding clasp comprising a central part at the ends of which are articulated two arms at the other ends of which the strands of the bracelet are attached, these arms coming to fold down and to be fixed on the central part in position. closed from the clasp.
  • a clasp of this type is described in patent CH.596.793.
  • the two articulated arms are fixed to the notch by their ends to a part provided in the center of the central part.
  • Another embodiment is described in patent CH.471.556.
  • the clasps of this type have the advantage of being well centered on the bracelet giving to the bracelet, in particular to watch straps, a harmonious and balanced appearance.
  • these clasps have the drawback of not being adjustable, since the ends of the two articulated arms must meet in the middle of the central part, on the one hand for their attachment and on the other hand for aesthetic reasons, in particular for hide the central part of the clasp.
  • the object of the invention is precisely to produce a clasp of the aforementioned type having possibilities of adjusting its length for its adaptation to the wrist of the wearer.
  • the bracelet clasp according to the invention is characterized in that the central part consists of two parts capable of being displaced longitudinally one inside the other, fixing means being provided for fixing together the two pieces in the desired relative position and that at least one of the articulated arms has lateral cheeks by which this arm is fixed to the notches on the sides of the widest piece of the central part in the closed position, a plate cover being provided at the end attached to the bracelet of one of the articulated arms to cover the ends of the arms attached to the bracelet and, if necessary, the space separating these ends, in the closed position.
  • the lateral fixing of the articulated arms on the central part makes it possible to fix them at any point in the widest part of the central part.
  • the use of a cover plate solves the problem of the space forming between the ends of the articulated arms.
  • This cover plate can also carry various decorations, for example that of a loop, which makes it possible to give the most different aspects to the clasp.
  • the clasp shown comprises an arcuate central part 1 at each of the ends 2 and 3 of which are articulated two arms 4 and 5 which are folded over the central part 1.
  • the ends 6 and 7 of the arms 4 and 5 are fixed respectively the ends of the strands 8 and 8a of a bracelet, for example a leather bracelet.
  • the central part 1 consists of a plate 9 having a U-shaped profile between the wings 9a and 9b from which is engaged a plate 10 having the same curvature as the plate 9 and provided with three rows 11, 12 and 13 of tapped holes in which are screwed three screws 14,15, and 16 embedded in the plate 9 and retained by this their head in this plate.
  • Three screws are provided to ensure good rigidity of the fixing, but in principle a single screw would suffice. It is thus possible to adapt the length of the bracelet to the wrist of the wearer by screwing the screws 14, 15 and 16 into the appropriate holes of the rows 11, 12 and 13, this without breaking the symmetry of the bracelet, that is to say tell the centered position of the clasp on the bracelet.
  • the two arms 4 and 5 are fixed to the central part 1 in the closed position by clipping, by two pairs of cheeks 17 and 18, respectively 19 and 20 which elastically pinch the wings 9a and 9b of the part 9.
  • the ends of these arms are at a variable distance depending on the relative position of the parts 9 and 10.
  • the problem posed by this variable distance was solved by means of a cover plate 21 provided with two cheeks 22 and 23 which come attach to the notch, by a slight notching, on the ends of the axis 7 of the attachment of the bracelet strand 8 to the clasp, thus ensuring additional retention and good application of the cover plate 21 on the bracelet.
  • the plate 21 is particularly suitable for receiving a decoration, in particular an element having the same appearance as the bracelet and giving the plate 21 the appearance of a light loop.
  • the bracelet can be attached to the clasp by any known means such as a screw pin, spring bar, etc.
  • the two joints of the clasp are hinged.
  • the relative positioning of the parts 9 and 10 of the clasp is not achieved by means of screws, but by means of notches formed on the one hand inside the wings 9a and 9b and on the other hand on the sides of the plate 10.
  • the displacement from one notch to the other is done by force, an additional elasticity can be given to the part 10 by a longitudinal elasticity slot.
  • Another solution would consist in _providing notches only in the wings 9a and 9b and mounting a small rotary eccentric in the part 10, this eccentric being provided with teeth which come to engage in the notches of the part 9.
  • This part 9 could be of tubular or split tubular shape, the wings 9a and 9b having a perpendicular bend directed towards the inside of the clasp.
  • a second embodiment is shown in Figures 4 to 6.
  • the elements taken up without modification of the first embodiment are designated by the same references.
  • the central part consists of a first part 24 having two parallel rectangular arms 25 and 26, slightly curved according to the curvature of the bracelet, and whose inner sides, facing one another, are shaped into a slide 27 to 28, the bottom of these slides being provided with teeth or notches of triangular profile.
  • the other part 29 has a single central arm 30 provided on each side with a toothing 31, respectively 32, with teeth of triangular profile.
  • This part 30 is engaged in the slides 27 and 28, so that the teeth of the teeth 31 and 32 are engaged in the teeth or notches of these slides.
  • the teeth of the teeth 31 and 32 can however pass over the teeth of the slides 27 and 28 by elastically spreading the arms 25 and 26, when a sufficient traction or thrust is exerted on the part 29, by retaining the part 24.
  • arm 5 provided with its cheeks 19 and 20, is articulated to part 24, while an arm 33 is articulated on the one hand to part 29 and on the other hand to the cover plate 21.
  • This arm 33 has two longitudinal central ribs 34 and 35, the ends of which have a small heel, directed outwards.
  • the part 29 has a longitudinal central cutout 36 whose width is slightly less than the maximum total width of the assembly of the two ribs 34 and 35.
  • the arm 5 When the clasp is closed, the arm 5 is first folded down on the part 24.
  • the cheeks 19 and 20 then have not only the function of fixing the arm 5 on the notch 24 on the notch, but of preventing separation of the arms 25 and 26, that is to say to prevent movement of the arm 30 relative to the arms 25 and 26.
  • the arm 33 is then folded over the part 29.
  • the ribs 34 and 35 engage to force, slightly bending, in the cutout 36 to fix it to the notch.
  • the cover plate 21 As for the cover plate 21 it is again fixed by its cheeks 22 and 23 on the hinge pin 7.
