Definitions

  • the subject of the present invention is a bracelet formed of rigid links directly articulated to each other and in which each articulation is formed by an articulation head limited by a surface in the shape of an arc of a cylinder, forming part of a link and by a housing. formed in the adjacent link, the articulation head being engaged in this housing on an arc of more than 180 °.
  • Bracelets of this kind are already known, executed in particular in the form of watch straps.
  • the links may consist of sections cut from a profile obtained for example by drawing. They are assembled by engagement of the articulation heads in the housings by a transverse relative displacement. The sections are then blocked with respect to one another, for example by crimping.
  • This technique makes it possible to produce bracelets of varying appearance by relatively simple means, the assembly work being reduced to a minimum.
  • Patent CH-A 573 731 describes, for example, a bracelet of this kind in which the articulation heads project from the thickness of the link and engage in housings formed in the edge of the adjacent link.
  • a defect of bracelets of this kind is that when two adjacent mail-Ions form an angle with respect to each other, a slit appears between them, which disturbs the aesthetic appearance of the bracelet and, on the other hand , promotes the introduction of dust or grime between the links.
  • each element consists of a link proper which forms the visible part of the element and a connecting element.
  • Each connecting element has on its edges the inverted volutes, mentioned above, and, in its central part, a groove used for securing the link itself. The latter constitutes the visible part of the bracelet element and, at the same time, ensures the locking of the joints, while allowing a slight pivoting movement.
  • the present invention aims, on the contrary, to produce bracelets, each element of which is formed in one piece.
  • the object of the present invention is to remedy these defects, by creating a bracelet of the kind mentioned which can be produced in the form of a gadroon or a bracelet with a small number of links.
  • the bracelet according to the invention is characterized in that the said housings are each limited by a cylinder arc lip which has an external face tangentially connecting to an external face homologous with another link.
  • the link of the bracelet shown in fig. 1 will preferably be produced by drawing a metal section, the length of which may be as large as desired, then cutting this section into sections of equal length or of different length.
  • the links can be made of steel, a copper alloy such as brass or nickel silver, silver or gold alloy, etc. They can also be made of plastic, and in this case, they could be produced by molding or by extrusion of a profile and sectioning, as for a production in metal.
  • the link in fig. 1 has a general shape in S. It comprises an articulation head 1 of cylindrical shape which constitutes one of the ends of the profile.
  • the surface in the shape of a cylinder arc 2 which extends over more than 180 ° and limits the articulation head 1, is extended on one side by a surface portion 3 with an S-profile.
  • This surface portion includes in particular a zone 3a in an arc of a cylinder which is coaxial with the head 1.
  • this zone 3a is a portion of cylindrical surface whose axis is common to that of the surface 2.
  • this surface 3 extends a surface 4 which is also S-shaped and is connected to the surface 2. The surfaces 3 and 4 thus delimit in the link of FIG.
  • connection zone 5 of constant thickness and less than the diameter of the cylindrical head 1.
  • the connection zone 5 is extended by an attachment lip 6 bounded by two coaxial cylindrical surfaces, ie an external surface 7 and an internal surface 8, these two surfaces connecting respectively to surface 3 and to surface 4.
  • connection zone 5 and of the attachment lip 6 is by construction equal to the difference between the radii of the portions of cylindrical surfaces 2 and 3a.
  • Fig. 2 shows how a certain number of links of the type of FIG. 1 can be assembled together to form a godron-type bracelet.
  • Each hooking lip 6 of a link is engaged between the articulation head 1 and the connection zone 5 of the adjacent link.
  • the cylindrical arc surface 7 of each hooking lip therefore connects tangentially to the S-shaped surface 3 of the adjacent link. This is what gives the bracelet seen from its external side an appearance imitating that of a series of small cylinders joined to each other.
  • Fig. 3 shows an embodiment of a bracelet which is not of the godron type, but in which, on the contrary, attempts have been made to reduce the number of links by giving each of them the form of a plate.
  • links A and B there is an articulation angle of the order of 35 °.
  • Each link comprises along one of its edges a head 9 of cylindrical shape limited by a surface in the shape of a cylinder arch 10 extending over more than 180 °.
  • the head 9 is connected to the central zone 11 of the link by a connection zone 12 of thickness less than the diameter of the head 9, while along the other edge of the central zone 11, extends a lip d hooking 13 curved in a cylinder arc and delimiting a housing 14 having the dimensions of the head 9.
  • the cylindrical surface 10 of the head 9 is also extended on one side by an S-shaped surface 15 of which a part 15a is coaxial to the head 9.
  • the catching lip 13 is limited externally by a surface in the arc of a cylinder 16 and internally by a surface 17 parallel to the surface 16. It can be seen, by considering the articulation between the links A and B of fig. 3, that the surfaces 16 and 15a are of the same radius, as are the surfaces 10 and 17.
  • the lip 13 surrounds the articulation head 9 over more than 180 °, for example the internal surface 17 has a cylinder arc shape at an angle of 225 °.
  • Figs. 4, 5 and 6 again show links of the type shown in FIG. 1.
  • the attachment lips of these links have an outer surface 18 (fig : 4) or 19 (fig. 5) or 20 (fig. 6) which is not a surface in the shape of a cylinder arch, but which is shaped so as to vary the aesthetics of the bracelet. It is dotted in the case of FIG. 4, which makes it possible to produce bracelets of the type called "godron-godron", while it forms a tabular rib in the case of FIG. 5 and an oval shape in FIG. 6.
  • FIG. 8 another embodiment of the bracelet according to the invention is seen.
  • This bracelet consists of links directly articulated to each other, but of two different types.
  • the links 101a, 102a, 103a, 104a are of the first type, that is to say with two hooking lips, while the intermediate links 101b, 102b, 103b are links of the second type with two heads d 'joint.
  • the links of the first type each have a central part, hooking lips 105 which are parts of constant thickness, curved in an arc of a circle so as to delimit, with the sides 106 and 107 of the part 103, two shaped housings.
  • cylindrical 108 and 109 are examples of the links 101a, 102a, 103a, 104a.
  • Type b links also include a central part 110 and on either side of this central part, articulation heads 111 and 11 of cylindrical shape, attached to part 1 10 by connection zones 113.
  • the central part 110 comprises an internal bead 114 which is limited on each side by a portion of surface in the shape of an arc of a cylinder, also coaxial with the corresponding articulation head and connected to this head by a delimiting surface which extends in the shape of an S and connects to the cylindrical surface of the head.
  • the elements 101b, 102b and 103b are limited by planar surfaces 115, 116 which extend opposite the flanks 107 and 106 of the adjacent links 101a, 102a and which constitute with these flanks. abutment surfaces.
  • the distance between the articulation heads 11 and 112 is equal to twice the thickness of the fastening tabs 104 and 105, so that, when the fastening lips of the links 101 a and 102a are each engaged on one of the heads joint 112 or 111, their outer surfaces are contiguous.
  • Each of the links 101a and 102a can pivot around the axis of the articulation head 112 or 111 while the outer surfaces of the hooking lips remain in contact with each other and tangent to each other. 'other.
  • the links are symmetrical with respect to a median plane.
  • the relative position of the three links located at the right end and designated by 103a, 103b and 104a shows the minimum radius of curvature that the bracelet can take. Only the central surfaces of the hooking lip links 101a, 102a, 103a and 104a are visible from the outside. These are curved surfaces which join tangentially to the outer surfaces of the lips.
  • the manufacture and assembly of the links shown in fig. 8 can be produced exactly as described with regard to bracelets with identical links of the first embodiments.
  • These elements can also be made, either of plastic, or of a metal such as brass, nickel silver or even steel, or also of a precious metal such as gold, silver or their alloys.
  • the manufacturing method applied will be stretching. We can however, after having cut the profile elements into short length segments in order to make the links, resume these elements on. a lathe or a milling machine to machine the elements which will ensure the blocking in the direction of the axis of the articulation heads.
  • the links 117a, 117b, 117c and the links 118a, 118b are links with hooking lips curved in the shape of a cylinder arc, while the links 118 are links with articulation heads.
  • the attachment lips 119 and 120 of the link 117a have the same arrangement and the same shape as the attachment lips 104 and 105 of the link 101 a while the two articulation heads 121 and 122 of the link 118a are arranged and arranged like the articulation heads 112 and 11 of the link 101b.
  • the central part of the link 118a is strongly swollen and has a projection 123 whose sides 124 and 125 are surfaces in the shape of an arc of a cylinder coaxial with the articulation heads 121 and 122 and located at a distance from the lateral face of these heads of articulation which is equal to the thickness of the attachment lips 119 and 120.
  • the maximum angle between the sides 127 and 128 of the link 118a and 129, 130 of each of the links 1 17a and 1 17b is achieved when the attachment lip 120 or 119 is fully engaged in the notch or housing delimited by the sides 124 and 125 of link 118a.
  • the extreme position is obtained when the sides 127 and 129 are in contact with each other and when the same is true for the sides 128 and 130 of the parts 118a and 117a.
  • This relative position is achieved for the two links 118b and 117c, while one has the other extreme position with the links 117d, 117e and 118c, see fig. 10.
