Definitions

  • the present invention relates to a folding clasp for a bracelet, in particular a folding clasp for a watch strap.
  • Watch straps are either open type or closed type.
  • open type bracelet we mean a bracelet whose two strands can be disunited. The ring that forms the watch and the bracelet can therefore be opened to put the bracelet on.
  • bracelet of the closed type one understands a bracelet whose two strands remain integral
  • the bracelets of the closed type generally comprise a folding clasp making it possible to increase the diameter of the ring formed by the bracelet and the watch in order to be able to pass their hand through it.
  • present invention relates precisely to a folding clasp for a bracelet, in particular for a closed type bracelet
  • folding buckles which all, however, generally comprise at least two mutually articulated blades and a clasp.
  • the blades In the closed position, the blades are generally folded one on the other or one next to the 'other, and retained in this position by an appropriate device
  • the clasp By actuating the clasp, the user has the possibility of releasing this device to unfold the articulated blades so as to increase the opening of the bracelet
  • Patent documents FR2'571' 228 , FR2'577'120, CH684151, CH678002 and CH635237 for example describe different types of folding clasps for bracelets
  • the deployment of the buckle must be sufficient to allow the passage of the hand through the opening of the bracelet in the open position, while sufficiently tightening the wrist in the closed position.
  • the common deployment buckles generally allow a variation of the circumference of the bracelet from three to six. about centimeters
  • the length blades in the closed position must be at least five centimeters to allow a deployment of five centimeters in the open position With three blades folding in accordion on one another, the length of the blades and the loop in the closed position is still 2.5 cm for example It is difficult to go beyond three superimposed blades without increasing the thickness of the clasp in an unacceptable way the
  • the blades forming the buckle are generally curved to correspond approximately to the curvature of the wrist of the wearer of the watch.
  • the curvature adopted is necessarily a compromise corresponding to a size of common wrist, and therefore not suitable for very thin wrists or on the contrary wrists larger than average For this reason, many people find the bracelets with folding clasp not very comfortable, and prefer bracelets of the open type yet less practice
  • An object of the present invention is to provide a folding clasp for an improved bracelet compared to the folding clasps of the prior art, in particular a more comfortable folding clasp
  • this object is achieved by means of a folding clasp for a bracelet comprising at least two blades hinged together so as to be able to adjust the opening of the bracelet, in which said blades are made of a flexible material capable of conforming to the shape of the wrist of the bracelet wearer
  • the folding clasp of the invention is made of a flexible material, for example a synthetic, composite or elastic metallic material
  • the blades of the folding clasp are deformable in the direction perpendicular to their own plane, so that the curvature of the closed loop can conform to the shape of the wrist. It is however preferable that the blades cannot deform in another direction, to guarantee a certain rigidity to the assembly and to prevent the blades of the buckle from protruding from the bracelet in the closed position and becoming apparent when they deform laterally
  • the blades of the buckle are therefore made of a material anisotropic, that is to say that the deformation of the blades caused by a force applied perpendicular to the plane (x, z) containing the said blades is greater than the deformation of the blades caused by an identical force applied according to any other direction
  • the blades can also be made up of isotropic elements, assembled in such a way that the entire loop has anisotropic properties
  • the blades of the bracelet are made of a composite material
  • Figure 1 a perspective view of a folding clasp in the closed position, shown in two blade deformation positions
  • Figure 2 a perspective view of the same folding clasp in the open position
  • Figure 3 a longitudinal section through the same folding clasp in the closed position, shown in two blade deformation positions
  • Figure 4 a longitudinal section through the same folding clasp in the open position
  • Figure 5 a cross section through the same folding clasp in the closed position
  • Figure 6 a cross section through the same folding clasp in the open position
  • the folding clasp described by way of example in FIGS. 1 to 6 generally comprises a loop 1 proper, formed by two lateral blades 10 connected by a hinge 12 to a central blade 1 1, thus as a clasp 2
  • the end of the central blade 1 1 is hingedly connected to a portion of the bracelet 4 while the end of the side blades 10 is connected by another articulation with the other portion of bracelet 4
  • Only the first metal links of the two ends of bracelet 4 are shown in the figures, it is obvious that the bracelet could also be made of leather, plastic, ceramic or any other suitable material
  • the central blade 1 1 is housed between the lateral blades 10 and in the same plane x, z, the clasp 2 making it possible to maintain this closed position
  • the clasp 2 comprises so general of the claws 20 integral with the central blade 1 1, as well as retaining means 23 integral with the side blades 10 and the other portion of the strap
  • the claws 20 are constituted by a tuning fork 20 which engages in the portion 23 at the end of the side blades 10
  • the clasp is closed simply by pressing on the tuning fork 20 or on the last link 4, and is held by the oblique portions of the lateral sides of the blades 10 or of the base of the clasp
  • it is necessary to press the ends 200 of the tuning fork so as to bring its two branches together and thus to release it from the retaining means 23
  • a safety cover 3, articulated by a pin 30, can be closed over the clasp so as to completely hide the tuning fork 20 and the retaining means 23
  • This cover optional, offers additional security in order to prevent the clasp from being able to be accidentally opened by a shock on one of the two portions 200 of the tuning fork
  • the cover is kept closed by pins 31 engaged in holes 40 on a part secured to the link of the bracelet 4
  • the blades 10, 1 1 of the loop 1 are made of a flexible material, preferably an anisotropic material having a high flexibility along the axis y perpendicular to the plane of the buckle blades and much lower flexibility along the x axis parallel to the wrist axis
  • the folding clasp 1 can thus be deformed so as to conform to the curvature of the wrist, as suggested in FIGS.
  • the blades 10, respectively 1 1 are made of composite material, for example HERE by means of a metallic longitudinal core 100, respectively 1 10, covered by a flexible material 101, respectively 1 1 1
  • the blades 10 and 1 1 are preferably connected to the other metallic or synthetic elements of the clasp by their metallic core 100, 1 10
  • the flexible coating 101, 1 1 1 can for example be made of a synthetic material, leather or rubber, preferably a material pleasant to the skin
  • the core 100, 1 10 could also be made of another material, for example synthetic material more rigid than the outer covering, or made of natural or synthetic fibers
  • Other types of materials and other composite structures can however be adopted, in particular according to aesthetic considerations It is also possible to cover only one face of the central core 100, 1 10 with a flexible material, for example only the face close to the wrist for increased wearing comfort, or only the external face for a decorative effect.
  • folding clasp comprising a central blade connected to one end of the bracelet and two lateral blades intended to be connected to the other end of the bracelet
  • the invention can be applied without difficulty to any type of folding buckle, for example to folding buckles of the butterfly type, wallet, etc., comprising two, three or more blades hinged in any way
  • the invention applies perfectly to folding clasps comprising a first blade connected by a first end in an articulated manner to a first strand of the bracelet, a second blade intended to be connected by a first end in an articulated manner to the second strand of the bracelet, as well as an intermediate blade , hingedly connected to the second end of the first blade and to the second extremi second blade tee
  • the folding clasp comprises a single blade whose thickness at at least one point is greatly reduced, so as to allow greater elastic deformation around this or these points, which thus act as an articulation for the thicker portions of the blade
