  • the invention relates to a ratchet locking assembly and, more specifically, to such an assembly allowing the use of fragile material, that is to say having no usable plastic field.
  • the object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing a fastening system not increasing the thickness of the respective members and being applicable to fragile materials.
  • the invention relates to an assembly of a part in the opening of a part characterized in that it comprises a system of connection between the part and the part comprising at least one ratchet device for to make the movements of the piece and the part compatible.
  • the invention therefore advantageously makes it possible to secure two elements in the same plane, that is to say without increasing the thickness of the elements, and without plastic deformation may be, depending on the nature of the materials, potentially destructive.
  • the invention relates to a timepiece characterized in that it comprises an assembly according to one of the preceding variants.
  • the invention relates to an assembly applicable to a fragile material, that is to say not having a plastic domain such as a material based on monocrystalline silicon.
  • This assembly was designed for applications in the watchmaking field.
  • other areas can be perfectly imagined as including aeronautics, jewelry or automotive.
  • this assembly is made necessary by the growing share of fragile materials such as those based on silicon, quartz, corundum or more generally ceramic.
  • fragile materials such as those based on silicon, quartz, corundum or more generally ceramic.
  • the present application proposes an assembly of a part, which can be integral with an axis, in the opening of a part, which can form a rotatably mounted part, characterized in that it comprises a system securing between the part and the part comprising at least one ratchet device for rendering integral the movements of the part and the part.
  • said at least one ratchet device comprises a resilient ratchet arm blocking an assembly of the tenon - mortise type in order to avoid relative movements between the part and the part. It is therefore understood that neither the part nor the part are plastically stressed to become solid with respect to each other.
  • the fastening system 1 comprises a single ratchet device 11.
  • the ratchet device 11 comprises an arm 13 forming a pawl which is formed in the part 3.

  • the ratchet device 11 also comprises a mortise 16 formed in the part 5 and intended to cooperate with the post 14 of the arm 13 to secure the part 3 with the part 5.
  • a la figure 1 it can also be seen that the portion 5 has a recess 15 which flares out as it moves away from the mortise 16 which is intended to form a cam 17 for the post 14.
  • the ratchet device 11 of the securing system 1 between the part 3 and the part 5 is activated as explained below.
  • part 3 and part 5 are manufactured.
  • the manufacturing steps of part 3 and part 5 have no consecutivity to respect and can even be carried out at the same time.
  • the part 5 is introduced into the opening 18 of the part 3 so that the post 14 slides laterally into the recess 15 of the part 5 as illustrated in FIG. figure 1 .
  • a relative displacement in rotation of the part 5 with respect to the part 3 is then printed in order to slide the post 14 against the cam 17 in order to gradually remove the pin 14 of the portion 5.
  • the relative movement is continued until the pin 14 tilts into the mortise 16 to resiliently lock the assembly 14 - tenon mortise 16 by the arm 13 forming a ratchet as illustrated in FIG. figure 2 .
  • the pin 14 of the part 3 is made integral in motion of the mortise 16 of the part 5 under the stress induced by the elastic return of the arm 13 forming a pawl.
