Definitions

  • Document CH 6663 522 proposes a clasp as defined above, allowing easy adjustment of the strap length.
  • the two arms are connected to each other by a double articulation, by means of a link.
  • the lower arm has two cutouts.
  • the head engages in the first or second of the cuts, thus adjusting the strap length.
  • the slide comprises two branches separated by a slit in the arm and two grooves formed in the walls of the branches adjacent to the slot, and the slide comprises two fingers extending laterally and which are arranged to be engaged each in one of the grooves to slide there.
  • the means of positioning are formed on the one hand by the end of the most close to the locking means, to define the first position, the fingers coming into abutment there, and on the other hand by extensions extending the grooves at their other end and forming a smaller angle therewith or equal to 90 °. These clearances are arranged so that the fingers can be engaged to define the second position.
  • the fingers are formed by the ends of a spring bar engaged in a hole in the arm, the slide is integral, arranged laterally and defining the axis of the articulation of the arms relative to each other.
  • the slide comprises two branches separated by an oblong opening made in one of the arms according to a longitudinal orientation.
  • the slide includes two flanges arranged on either side of the opening and a body engaged in the slot and connecting the two flanges, one of them being arranged to serve as an articulated support on the other arm.
  • the positioning means are formed of a leaves through the end of the opening closest to the means of locking, to define the first position, and on the other hand by a drop in which one of the flanges engages in the second position.
  • the slide is made of plastic and the flanges are friction mounted on the arm having the opening.
  • the arm pivotally mounted on one of the flanges forms a cooperating eccentric with the other arm and arranged so as to lock the slide in the slides when the arms are closed.
  • the clasps shown in the drawing have two arms 10 and 12 respectively lower and upper, curved and each provided with a concave face identified by the letter a and a convex face identified by the letter b , the concave face 12a of the upper arm being adjacent to the convex face 10b of the lower arm in the closed position of the clasp.
  • the arm 10 is intended to be in contact with the skin of the user by its concave face 10a.
  • the upper arm 12 has a thickness such that it is elastically deformable in bending, the deformation tending to vary its curvature.
  • Locking means 14 maintain the two arms 10 and 12 in the closed position. They comprise a first part 16 formed of two cuts 16a and 16b made in the arm 10, and a second part formed of a head 18 integral with the arm 12 and which has a structure conical, extending from the arm 12 outwards and the top of which is bulging. In this way, when the upper arm 12 is applied against the lower arm 10, the head 18 comes to bear by its curved part against the edge of one of the holes 16. Because of the elasticity of the arm 12, and the pressure applied, the head 18 engages in the cut, its taper ensuring the notch function.
  • the clasp further comprises connecting means 20 of the arms 10 and 12 more specifically comprising a slide 21, a slide 22 and a hinge 24.
  • the slide 21 is formed of two branches 10c and 10d separated by a slot 10e, arranged at the end of the arm 10.
  • the sides of the arms 10c and 10d defining the edges of the slot 10th are each provided with a groove 26 according to the shape of the arm, and with a clearance 28 extending the groove 26 at the free end of the branches, direction of the concave part of the arm and forming with the groove 26 an angle less than or equal to 90 °.
  • the slide 22 is formed by a spring bar comprising a body 22a and two fingers 22b arranged on either side of the body, of a length substantially equal to the depth of the grooves 26 in which they are engaged (fig. 1c).
  • the arm 12 is pierced, at its end associated with the connecting means 20, a hole 12c extending laterally and in which the body 22a of the bar is engaged, the hole 12c and the bar together forming the hinge 24, which allows relative pivoting of the arms 10 and 12 about an axis A-A substantially parallel to their lower and upper faces.
  • Each of the arms 10 and 12 is provided, at its free end, with knuckles 29 allowing the attachment of the strands of a bracelet, of metal or flexible material.
  • an adjustment of the length of the bracelet can be do this by bringing the slider 22 to one or the other of the ends of the grooves 26.
  • the slide 22 bears against the bottom 26a of the grooves 26.
  • the tilting of the arm 12 towards the arm 10 brings the head 18 in a position such that a pressure exerted on the arm 12 makes it engage notch in the cutout 16b.
  • the bracelet is at its shortest length. To lengthen it, it is sufficient, after having separated the two arms, by removing the head 18 from the cutout 16b, to slide the slide 22 in the slide 21, until engaging the fingers 22b in the clearances 28. In this position, the arm 12 can be folded back towards the arm 10, the head 18 then being positioned so as to engage notch in the cutout 16a, while the arm 12 is retained by the fingers 22b housed in the recesses 28.
  • FIG. 2a to 2c also includes two arms 10 and 12, locking means 14 identical to those described previously as well as connecting means 20 comprising a slide 21, a slide 22 and a hinge 24.
  • the slide 21 is formed of two branches 10f and 10g separated by an oblong opening 10h located at the end of the arm 10 opposite to that comprising the cutouts 16a and 16b.
  • the slide 22 includes two flanges 22c and 22d, joined respectively to the faces 10b and 10a of the arm 10 and connected together by a body 22e engaged and crossing the opening 10h from face 10a to face 10b.
  • the flanges 22c and 22d and the body 22e are arranged so that the slide 22 is frictionally movable on slide 21. In this way, the positioning of the slide 22 is facilitated.
  • the flange 22c is provided with a hole in which is freely engaged a pin 30 driven into the arm 12, to form the hinge 24.
  • the arm 10 at the end of its part comprising the branches 10f and 10g, includes a recess 10j arranged so that the flange 22d y come into support when the slide 22 is at the outer end from opening 10am. In this way, the offset 10j ensures the positioning of the slide 22 when the head 18 must be engaged in the cutout 16a.
  • the slider 22 is brought into stop at the other end of the opening 10h.
  • arm 12 is positioned with reference to arm 10 in its two closing positions.
  • the eccentric of the end 12d bears against the face 10b of the arm 10 and tends to press the flange 22d against the face 10a of the arm 10.
  • the thickness of the arm 10 goes advantageously by decreasing the offset 10j towards the end of the opening 10h located on the side of the cutout 16a, until reaching equal thicknesses in the positions in which the slide is located 22 when the clasp is closed.
