Definitions

  • the present invention relates to a bracelet clasp having at least two arms articulated to one another by one of their respective ends, a locking device for holding the free ends of these two branches in the folded position and means for link between their free ends and the respective ends of a bracelet.
  • This type of clasp is well known see CH-A-689 931 especially in the field of clasps for watch straps.
  • the folding branches of the clasp can increase very significantly the length of the bracelet in the open position of the clasp, which allows to pass the wristwatch around the hand without the need to separate the bracelet.
  • a clasp with folding branches comprising one or two levers articulated about axes perpendicular to one of the branches of the bracelet and returned to the locking position by a spring disposed transversely to the clasp blades, so that these levers are accessible on both side faces opposite of the clasp on which they protrude.
  • These levers each have an internal rim which extends in a plane perpendicular to the respective pivot axes of the levers and which are intended to engage on complementary edges of a locking member secured to one end of another branch of the clasp.
  • the object of the present invention is to overcome, at least in part, the aforementioned drawbacks.
  • this invention relates to a bracelet clasp according to the definition given by claim 1.
  • the lever of the clasp according to the invention acts well on the elastic return means as a lever, which makes it allows to obtain a reduction of the force exerted on it to bend the elastic return means. With this reduction of the manual force exerted on the lever to open the clasp, it can increase the strength of the elastic return means and thus increase the force exerted on the locking hook. This force continues to be exercised in the closed position, keeping the branches tight against each other, thus catching up the play between the branches of the clasp.
  • the clasp illustrated in Figures 1 to 4 comprises two branches 1, 2 articulated by one of their ends around an axis 3 ( Figure 4).
  • the free end of the branch 1 has a fastening element 4 which, in this embodiment, is in the form of a transverse element, parallel to the hinge axis 3.
  • This fastening element 4 is located in a portion 1a of the free end of the branch 1, curved outwards.
  • a space is provided between this fastening element 4 and the bottom of this curved portion la to allow insertion of a fastening member between the fastening element 4 and the bottom of the curved portion 1a as will be explained. thereafter.
  • This same free end is still integral with two axes of joints 5, 6, parallel to the hinge axis 3 of the branches 1, 2.
  • One of these axes serves to the articulation of a locking cover 7, while the other serves to articulate an end of one of the strands of the bracelet (not shown).
  • the free end of the branch 2 is thicker than the rest of this branch, to receive a hinge pin 8. This extra thickness is obtained by bending the face of this branch 2 facing the branch 1, so that closed position, this curved face of the branch 2 substantially matches the shape of the beginning of the curved portion la because it is shorter than the branch 1, as can be seen in Figure 3.
  • a connecting member 9 is articulated to the free end of the branch 2 about the hinge axis 8 to allow it to free articulation of at least 180 ° to facilitate the deployment of this branch 2 for the free passage of the hand in the open position.
  • This connecting member 9 comprises two other axes 10 and 11.
  • the axis 10 serves for the articulation of a locking lever 12 and the axis 11 serves to connect a cover 13.
  • This has two side walls parallel in which is formed a plurality of pairs of positioning elements formed of circular impressions 14 on their opposite internal faces, for fixing a bar (not shown) in one or the other pair of fingerprints, following the desired length for the bracelet.
  • the connecting member 9 has a surface 9a adjacent to the inner face of the upper wall of the cover 13. This surface 9a serves to block the pivoting of the cover 13 about the axis 11.
  • a spring 15 bears on a rod 16 secured to the connecting member 9, passes around the hinge axis 10 between this connecting member 9 and the locking lever 12 and the other end of this spring 15 bears against the inner face of the upper wall of the locking lever 12.
  • this spring creates a torque on the locking lever 12 which tends to do so turn counterclockwise in Figures 1-4.
  • two springs 15 are arranged along the pivot axis 10, on either side of the connecting member 9 which is at the center of the pivot axis 10.
  • the locking lever 12 carries a locking hook 17 shaped to be able to engage between the locking element 4 integral with the free end of the branch 1 and the bottom of the curved portion 1a of this branch 1, in which position it is held by the torque applied to it by the springs 15.
  • the rear end of the locking lever 12, situated under the front end of the cover 13 transmits a torque to the latter via the the link member 9.
  • This pair makes it possible to keep the lid 13 very close, or even to apply it against the bracelet strand, the end of which is fixed in one of the pairs of positioning elements formed of impressions 14 and prevents it from departing. This avoids the cover 13 the risk of clinging during movements made by the person wearing a bracelet with the clasp according to the invention.
  • a clasp whose cover can move freely from the bracelet due to its play, affects the appearance of this clasp and is a factor of depreciation.
  • the locking cover 7 is provided as additional security. It is intended to cover the locking lever 12 by tilting, once the locking hook 17 has been hooked to the locking element 4. This locking cover 7 can be held in the folded position by two fingerprints 7a provided on the internal faces of its side walls which can engage on the opposite ends of the pivot axis 10 of the lever 12 which then project from the side faces of the lever 12 and can retract against the pressure a coil spring disposed in the pivot axis 10, like a well-known piston bar for attaching a bracelet to the horns of a wristwatch box.
  • the second embodiment differs essentially from the first embodiment because of the absence of the second locking cover 7. Another difference lies in the fact that an axis 20 serves for the articulation of the lever 22 on the connecting member 19, and to connect the lid 23 to this connecting member 19.
  • the lever 22 is covered with a cover 28 which increases the length of the lever arm.
  • This lever 22 carries a hook 27 intended to hook to the locking element 4 of the branch 1 exactly as in the first embodiment.
  • the third embodiment illustrated in FIG. 5 is intended to integrate the clasp into a bracelet to articulated links formed of at least three longitudinal rows of links, in which the links of a row are offset longitudinally by half a step from those of the adjacent row, the pitch corresponding to the longitudinal distance between two adjacent links of the same row.
  • the free end of the branch 1 is integral with at least one link 29, several similar links can be aligned transversely to the link 29 according to the number of rows of links that includes the bracelet to be connected to the clasp.
  • This or these links 29 comprise a transverse locking rod 34 and a screw shaft 35 to make the connection with the bracelet (not shown).
  • the connecting member 30 which is articulated about an articulation axis 31, at the free end of the branch 2, comprises a second hinge axis 32 which is articulated the locking lever 33 which is present in the external form of a link 33a which is fixed a gripping element 33b.
  • the lower face front portion of the locking lever 33 is recessed to form a hook 33c.
  • a housing 33d is provided in the rear portion of the underside of the link lever 33a for housing a cylinder 36 which encloses a coil spring and a piston 37, pressed outwardly by the coil spring.
  • This piston 37 is limited by its rear portion of larger diameter, so that it stops at the end of the stroke, against the front face of the cylinder 36 through an opening which passes the visible outer portion, of smaller diameter of the piston 37.
  • the outer end of the piston 37 rests against the upper face of the branch 2 of the clasp and applies to the lever 33 a torque around the axis of articulation 32 years the opposite direction to that needles of the watch.
  • the hinge axis 32 of the connecting member is also used for the articulation of two connecting links 38, located transversely on either side of the locking lever 33 in the form of a link 33a.
  • These connecting links 38 comprise a hinge pin 39 to allow the attachment of an end of a strand of the bracelet (not shown).
  • the hooking of the locking hook 33c on the locking rod 34 is effected by raising the lever 33 or by rotating it clockwise about the hinge axis 32 against the force of the return spring exerted via the piston 37.
