Definitions

  • the present invention relates to hinges, in particular for a bracelet or a wristwatch. It relates to a hinge of the type comprising a female member provided with a tube, a male member provided with a lug and articulated in the female member, around an axis serving as a hinge axis. , and an axial lock.
  • each hinge comprises two male members, two female members and a latch formed by a spring which bears against an arm connecting one of these members to the body of the link.
  • the disassembly of such bracelets requires the use of objects allowing the movement of the spring in lieu of a lock, which can cause problems, especially during the sale, in the case where the seller is not a watchmaker.
  • the object of the present invention is to produce a lock hinge, the disassembly of which does not require any particular tool.
  • the bolt comprises hooking means made of two parts respectively secured to the male and female members and elastically deformable locking means, for locking the two parts below a traction limit value. axial exerted on the organs.
  • the length setting or the change of the bracelet can be done by a simple shearing movement on two neighboring links or on the bracelet and the case.
  • FR-A-2 300 197 is certainly known for hinges comprising elastically deformable locking means for locking the male and female members. These non-unlockable plastic hinges are intended for use in furniture subject to temperature variations due to the flexibility of the plastic. Although very similar, by its structure, to the hinge according to the invention, the hinge described in FR-A-2 300 197 could not without other application be applied to the manufacture of a bracelet. In addition, even adapted, it could not resolve the problem of setting the length or changing the bracelet, since it is not removable.
  • the hinge comprises a female member 10 provided with a tube 12, a male member 14 provided with a body 15 and a stud 16 articulated in the female member 10 around an axis 18 acting as an axis of articulation of the hinge, and an axial lock 20.
  • This lock comprises attachment means comprising on the one hand a retaining element 22, on the other hand four hooking elements 24, and locking means 26 elastically deformable, for locking the elements below a limit value of axial traction exerted on the members 10 and 14.
  • the first element 22 is formed by a bead 28 which protrudes radially outward from an axial portion 29 of the male member 14, the latter being integral with the stud 16.
  • this bead is formed by a ball-shaped portion whose center is located on the axis 18 and integral with the portion 29.
  • the second elements 24 each have a claw 30 movable elastically and cooperating with the bead 28 to form the attachment means.
  • These claws 30 extend radially inwards and are each connected to the female member, and more precisely to a plug 32 closing one of the ends of the tube 12, by an elastic strip 34 extending axially and forming the locking means 26.
  • the locking means 26 are integral with the second elements 24 and connect them to the female member 10.
  • the elements 22 and 24 of the attachment means and the locking means 26 are arranged so that the claws 30 enclose the bead 28, the elastic strips 34 exerting a force which tends to oppose the spacing of the claws 30 in the radial direction. If a tangent t is drawn at the bead 28, and passing through the place of contact of the claws 30, this tangent forms an angle a with the axis 18, advantageously between 30 and 70 ° (fig. 2). Thanks to this configuration, the application of axial traction on the female 10 and male 14 members induces a force tending to spread the claws 30.
  • the hinge will be all the more difficult to disassemble the greater the force of the elastic strips 34 and the greater the angle ⁇ formed by the axis 18 and the tangent t.
  • FIG. 4 and 5 differs from that of Figures 1, 2 and 3 in that the second element 24 of the hooking means and the locking means 26 are formed together of a ring 36 having a radial slot 38 and positioned axially in a radial groove 40 defined in the female member 10 by the plug 32 and a bearing 12a that the tube 12 comprises. More precisely, the element 24 is formed by the inner edge of the ring 36.
  • the 'male member 14 and the first element 22 are the same as those of the embodiment shown in Figures 1 and 2. Thanks to the fact that the ring is split, it is thus made elastically deformable, which allows it to act as a means lock 26.
  • the ring In order to increase the elasticity of the ring, it can have a clover shape, pierced with a triangular hole rather than being annular.
  • the application of an axial force on the female 10 and male 14 members causes the spacing of the ring 36 which allows the passage of the bead 28 in one direction or the other, depending on whether it be a tensile or compressive force.
  • the retaining element 22 is secured to the male member 14, while the latching elements 24 as well as the locking means 26 are secured to the female member 10.
  • the retaining element 22 is integral with the female member 10. It is formed of a rigid ring 41 locked axially in the radial groove 40 defined in the member female 10 by the plug 32 and the bearing 12a of the tube 12.
  • the hooking elements 24, four in number, are formed by claws 42 which extend radially outwards.
  • the locking means 26 comprise four elastic strips 44, extending axially and connecting the claws 42 to the stud 16.
  • the blanks of the claws 42 form an acute angle with the axis 18, so that when an axial force is exerted on the male and female organs, it causes a deflection of the lamellae 44 which tend to cause the claws 42 to approach each other, until they can pass through the central hole of the ring 41.
  • the attachment means comprise a rigid retaining element, and one or more attachment elements resiliently associated with the male or female member. It is quite obvious that by combining the male member of FIG. 6 with the female member of FIG. 4, it is possible to obtain another embodiment in which all the elements of the hooking means are elastically connected. to their respective bodies. This method of reducing the deflection of the lamellae.
  • each of the links 46a to 46c carries on one of its edges a female member 10, welded by the outside face of the tube 12, and on the opposite edge a male member 14, welded by its body 15, the the male member of one of the links being articulated in the female member of the neighboring link.
  • the box 48 carries a female member 10 and a male member 14.
  • This type of attachment of the bracelet to the box can also be used with a flexible bracelet, in leather for example, the neighboring end of the box then being secured to a rigid part carrying one of the members of the hinge.
  • the hinge as described and claimed makes it possible to produce bracelets whose length adjustment does not require any particular means, or watches in which the change of the bracelet is done so easily that it allows the wearer himself to perform it at his convenience, without having to call in a specialist.
