Definitions

  • the invention relates to a link bracelet, in particular for a watch, and more particularly to a link bracelet, the visible parts of which are formed of decorative elements made of a hard material, which cover frames of links of machinable material, and which are fixed to these. link frames.
  • the decorative pieces are fixed to the main faces of the articulated plates, by welding.
  • This method of fixation presents difficulties.
  • the elements to be fixed on the metal frame are made of sintered hard metal or ceramic, welding causes the appearance in the assembly of unacceptable mechanical stresses.
  • Document EP 0 015 242 B1 also describes a bracelet formed of links, one of the faces of which is covered with a thin protective part made of sintered hard metal. The fixing of this protective part on the body of the link is ensured by two studs welded against one face of the protective part and which are retained in through holes in the body of the link by rivets.
  • the bracelets produced according to the above document also have the drawback of not having protection for the lateral parts of the links, these therefore being liable to be damaged during an impact.
  • the link frames being partially visible, and having a color and texture different from that of the protective parts, the bracelet described cannot have the appearance of a bracelet, the links of which are made in one piece. .
  • the German document DGM 8 904 193 describes a bracelet link whose visible parts are entirely covered by protective parts, and which can therefore have the appearance of a link made in one piece.
  • This bracelet link firstly comprises a first protective part having substantially the shape of a rectangular plate whose upper face comprises near each of its ends a raised area constituting a shoulder, and which forms a base on which are still fixed studs.
  • a link frame constituted by a plate provided with hinges rests on this first protective part, and said studs are engaged in holes in the frame of link to ensure orientation.
  • a second protective part forming a cap is driven out on the two shoulders of the first protective part. This cap covers and hides the link frame as well as the two shoulders. Note that the cap being driven on shoulders formed on the upper face of the base, its edges do not cover the side faces of this first protective part. These side faces therefore remain visible when the bracelet is worn on the wrist.
  • the latter embodiment is also not suitable when the protective parts are made of sintered hard metal. Indeed, one cannot demand elastic deformations of a sintered hard metal part. To allow the cap to be held securely fixed on the base by hunting it is therefore necessary to produce parts sized extremely precisely. As the pieces shrink more considerably during sintering, it is necessary to resort to extremely laborious subsequent machining.
  • An object of the present invention is to remedy the drawbacks of the prior art by providing a bracelet formed of links hinged together comprising an inner face, an outer face and two lateral faces, said links comprising a link frame provided with hinges, first and second protective parts and means for fixing said protective parts to said link frame, said bracelet being characterized in that said first protective piece completely covers the inner face of said link frame, in that said second protective part comprises a central part which completely covers the external face of said link frame, and two lateral parts which cover the lateral faces of the link frame and of the first protective part, and in that said means of fixing comprise at least one stud integral with said second protective part, said stud extending through holes made respectively in said frame of the link and in said first protective part, and being retained in said holes by a rivet at its distal end.
  • a bracelet forms a substantially circular band surrounding an arm.
  • inner face of a link is therefore meant the face of this link which is in contact with the arm, and by outer face of a link, the face of the latter which is opposite to the inner face.
  • outer face of a link the face of the latter which is opposite to the inner face.
  • side face of a link means the faces of the latter which are substantially parallel to the plane of symmetry of the bracelet which cuts the links in half.
  • An advantage of the present invention consists in that the visible parts of the links are entirely covered by protective parts which can be of easy-to-make shapes made of sintered hard metal or ceramic.
  • link reinforcements can be of simple shape and easy to machine since their internal faces are also covered by protective parts, and that consequently their shape does not determine the shape of the inner surface of the bracelet.
  • Another advantage of the present invention lies in the fact that the two lateral parts of the second protective part cover the lateral faces of the first protective part, the latter therefore not being visible when the bracelet is worn on the wrist.
  • the present invention therefore makes it possible, if desired, to produce the first protective part from an easily machinable metal, only the second protective part always being made from a hard material.
  • the means for fixing the protective parts to the frame of the link comprise a single riveted stud which holds the parts together.
  • the parts are on the other hand prevented from rotating with respect to each other by the presence of the lateral parts of the second protective part which extend opposite the lateral faces of the two other elements.
  • the link 1 is formed of a link body 2 of machinable metal and two protective parts 4, 6, at least one of these protective parts 6 being made of hard material.
  • the body of the link 2 consists of a plate 3 and hinges 14 integral with this plate. It is preferably produced by stamping from a steel sheet, the ends of the sheet then being rolled up to form the hinges 14.
  • the protective parts 4, 6 are, as we have already said, preferably made of sintered hard metal or ceramic.
  • the first protective part 4 and shaped to completely cover the inner face of the plate 3 of the frame of the link 2.
  • the second protective part 6 comprises a central part 7 which completely covers the outer face of the plate 3, and two lateral parts 8 which extend opposite the lateral faces of the frame 2 of the link and the first protective part.
  • the thickness of the second protective part 6 at the level of the lateral parts 8 is substantially equal to its thickness at the level of the central part 7 plus the thickness of the first protective part 4 and that of the plate 3 of the frame 2 of the link. Consequently, when these elements are assembled, the surface of the first protective part is flush between the two shoulders 8a and 8b formed by the lateral parts 8 of the second protective part 6, and therefore, the internal surface of the link is substantially flat.
  • the lateral faces of the body of the link 2 and of the first protective part 4 being moreover entirely hidden by the lateral parts 8 of the second protective part 6, the link has the appearance of an element produced in one piece .
  • the link 1 is kept assembled by a stud 10 of deformable metal secured to the second protective part 6.
  • This stud 10 is preferably constituted by a steel or brass cylinder which is welded by one of its ends to the part central 7 of the second protective part 6.
  • the stud 10 passes through holes 12, 13 made respectively in the link body 2 and in the first protective part 4, and it is retained in these by a rivet of its end 10a in a counterbore 13a of said first protective part.
