Definitions

  • the invention relates to a crimping bezel, comprising an upper body, extending around an axis defining a direction for driving said bezel into a housing of a piece of jewelery or jewelery or watchmaking, and comprising a first surface arranged to receive a component to be crimped, at least one crimping element arranged to hold said component to be crimped, and, aligned with said upper body, a lower body comprising a second front surface.
  • the invention also relates to a crimping assembly comprising a piece of jewelery or jewelery or timepieces, which comprises at least one housing arranged to receive such a crimping bezel.
  • the invention also relates to a method for producing a decorative assembly with crimping of a component to be crimped arranged to cooperate with a bezel in a housing of a piece of jewelery or jewelery or timepieces.
  • the invention relates to the field of crimping added elements, in particular crimping components such as stones, pearls, cameos or the like, on pieces of jewelery or jewelery or timepieces.
  • Modern pieces of jewelery or jewelery or watchmaking often include structural elements such as cases, crystals, bracelet links, or the like, which are made of materials that do not exhibit plastic deformation, often hard and/or fragile. , such as ceramics, silicon, sapphire, intermetallic alloys or composites with a metal, natural or polymer matrix.
  • bezels made of elastic or shape-memory material are a solution that allows the bezel to be well maintained in its housing, but which is not very suitable for fixing very small decorative elements, and the installation is tricky, requiring more qualified personnel; the cost of such a kitten is, moreover, quite high, and the choice of an elastic material is difficult to reconcile with the deformation of crimping elements such as claws or grains, generally employed for maintaining the decorative element on the kitten. Moreover, such elastic kittens are not aesthetic.
  • the invention proposes to provide a simple and economical solution to the problem of crimping decorative elements on structural elements made of hard material.
  • the invention relates to a crimping bezel according to claim 1.
  • the invention also relates to a crimping assembly comprising a piece of jewelery or jewelery or timepieces, which comprises at least one housing arranged to receive such a crimping bezel.
  • the invention also relates to a method for producing a decorative assembly with crimping of a component to be crimped arranged to cooperate with a bezel in a housing of a piece of jewelery or jewelery or timepieces.
  • the invention relates to the crimping of decorative elements, in particular but not limited to stones, on a piece of jewelery or jewelery or timepieces.
  • the invention relates more particularly to the case of such pieces of jewelery or jewelery or timepieces, which comprise structural elements made of hard material, at the level of which a setting must be made.
  • the manufacture of reception housings for decorative elements is sometimes very difficult to achieve, depending on the nature of the material concerned, and the method of manufacture of this structural element itself. For example, in a material such as a ceramic, or a sapphire, or the like, a housing with an undercut cannot be made, and a cylindrical housing is already considered a good result. The problem is amplified when both the decorative crimp element and the housing are very small. It should be noted that the use of a kitten is unavoidable in such cases.
  • the object of the invention is to reconcile the secure holding of the decorative element to be crimped in its bezel, and of the bezel in its housing, the correct geometrical positioning of the decorative element to be crimped and of its bezel relative to the housing, the control of the cost of the components, the aesthetic aspect of the assembly, and the carrying out of the operation of laying the bezel and crimping the decorative element by personnel of average qualification.
  • the invention proposes to produce a bezel of a particular shape, simple to machine, of very moderate cost, and of aesthetics similar to that of a standard bezel.
  • the invention relates to a crimping bezel 1, comprising an upper body 15, extending around an axis A defining a direction for driving said bezel 1 into a housing 8 of a piece of jewelery or jewelery or clockwork 9.

  • the kitten 1 comprises, at least between the upper body 15 and the lower body 16, at least one deformable zone 7, which is plastically deformable under the action of an at least axial force applied to the kitten 1 according to the hunting direction, greater than a predetermined hunting effort, to bring the kitten 1 into a constrained state.
  • this at least one deformable zone 7 is irreversibly deformed and/or fractured, or else in the form of a bead radially pushing back a peripheral surface 3 of the kitten 1 towards a side wall of the housing 8 during the application of this force, and/or in the form of a fault pushing the upper body 15 radially towards such a side wall during the application of this force.
  • the upper body 15 comprises such a peripheral surface 3, which is arranged for guiding and holding the bezel 1 in complementary cooperation with a housing 8 of a piece of jewelery or jewelery or watchmaking 9.
  • the figures illustrate the most common case where the housing 8 is a female element, for example a bore or a pocket, and where the kitten 1 is inserted into the housing 8; however, the invention is applicable to the opposite case, not illustrated by the figures, where the housing 8 is a male element, and where the bezel 1 caps this male element.

  • peripheral surface 3 is located between the first axial side and the second axial side, and at least one such foot 16 is arranged in the vicinity of the second surface 6.

  • the bezel 1 includes a removable cap 14, which is arranged to be pushed out or screwed along the axis A to prevent the radial shrinkage of the foot 16 after the deformation of the deformable zone 7 and the cooperation of the bezel 1 in support of friction with housing 8.
  • the upper body 15 comprises, on the side opposite the first axial side, a first lip 150 which is deformable during deformation of a deformable zone 7 with a first radial part 151 arranged to exert on the housing 8, in the constrained state of the kitten 1, a friction force greater than that exerted by the rest of the upper body 15 or by the foot 16.
