Definitions

  • the present invention relates to an articulated bracelet, in particular for a watch. It relates more particularly to a bracelet formed of a series of bars arranged parallel to each other and held in place by means of connecting elements which can pivot around the axes of the bars.
  • Such bracelets are well known and there are a wide variety of connecting devices between bars.
  • the bars are cylindrical rods having a length which increases as they approach the end of the strap intended to be fixed to a watch case.
  • the connecting elements, connecting two adjacent bars are each formed of two rings welded together at a point on their periphery. The lateral retention of the connecting elements on the bars is obtained by welding one of the rings of each element on the bar which passes through it. On the ends of the bars are still welded heads against which the rings of the connecting elements come to bear in order to allow the bracelet to better resist transverse forces.
  • this bracelet requires a lot of different components, which are assembled by delicate welding operations, resulting in a high manufacturing price.
  • the present invention proposes to overcome these drawbacks by making a simple, inexpensive articulated bracelet, using few different parts and which can be easily assembled and disassembled without special tools.
  • the bracelet according to the invention comprising bars arranged parallel to each other and perpendicular to the longitudinal axis of the bracelet, and connecting elements intended to connect a bar to an adjacent bar, while remaining free to pivot around the axes of the bars, is particularly remarkable in that each of the connecting elements is formed of two substantially planar hooks, and of a bridge connecting the two hooks together, each hook, which constitutes one of the two ends of this element , is provided with a transverse hole, with an axis perpendicular to the plane of the hook, this hole opening towards the outside by a lateral slot, arranged perpendicular to the right joining the centers of the holes, the width of the slot being less than the diameter of the hole so that each end of the connecting element can be forcibly engaged, by elastic deformation of the corresponding hook, in a groove of re evolution practiced in each bar, the diameter of the groove being equal to the diameter of the hole of the hook.
  • fig. 1a shows two adjacent bars, referenced 1 and 2, of an embodiment of the bracelet according to the invention.
  • the bars in this embodiment are cylindrical and their surface is smooth, but different shapes, while remaining substantially cylindrical, could also be suitable, just as the surface could carry decorative patterns, such as facets.
  • Each bar carries two grooves of the same shape 3 and 4, located equidistant from its ends.
  • the bottom of each groove is cylindrical and the lateral faces are flat.
  • Fig. 1b shows a connecting element 5, cut through the middle.
  • This element comprises a first hook 6, a second hook 7, drawn respectively above the bars 1 and 2, and a bridge 8 connecting one hook to the other.
  • the connecting element is delimited by two main plane faces, parallel to each other and to an axis joining the midpoints of the two hooks, the distance between the main faces defining the thickness of the element.
  • Each hook is delimited externally, for its part, by a cylindrical face, perpendicular to the main faces, the diameter of which is substantially equal to the diameter of the bars.
  • the bridge 8 has a rectangular section, one of the dimensions corresponding to the thickness of the element 5 while the other dimension must be at most equal to the diameter of a bar.
  • the length of the bridge which determines the distance between the bars of the bracelet, is only chosen according to aesthetic criteria.
  • the diameter of these holes is equal to the diameter of the cylindrical part of the grooves 3 and 4.
  • the slot is delimited by two plane faces parallel to each other and perpendicular to the main faces as well as to the axis joining the centers of the holes 9 and 10. The distance separating these faces determines the width of the slot 11 whose axis of symmetry passes through the center of the hole 9.
  • a slot 12, similar to the preceding slot, is made in the same way in the hook 7.
  • the width of the slots 11 and 12 is chosen to be slightly less than the diameter of the grooves 3 and 4.
  • the connecting element 5 can be fixed on the bars by forcing the hook 6 into the groove 3 of the bar 1 and the hook 7 into the groove 3 of the bar 2.
  • the force exerted by the grooves on the faces of the slots then elastically deforms the hooks by opening them. This allows the grooves 3, penetrating to the bottom of the hooks 6 and 7, to take place respectively in the holes 9 and 10.
  • the hooks can return to their original shape, trapping the grooves in this position which leaves the bars the possibility of pivoting about their axis.
  • the bar and the connecting element which have just been described can be obtained respectively by bar turning and stamping, that is to say by current and inexpensive operations, which are well suited to mass production. With these two parts only, it is possible to make an advantageous bracelet, an embodiment of which is shown in FIG. 2.
  • the width of the grooves 3 and 4 is equal to twice the thickness of a connecting element, allowing two hooks to be placed in the same groove.
  • an arbitrary number of bars can be linked together by placing the connecting elements 5 alternately on the side of the edge of the bars, or on the side of their middle, in the series of grooves 3 and in the series of grooves 4.
  • the connecting elements 5 of a series of grooves are therefore arranged one after the other to form a row.
  • At least some of the bars preferably made of steel or brass, can be covered, except at the location of the grooves, by a tube made of a different material, for example a noble metal such than gold.
  • the hooks 6 and 7 of a connecting element 5 must have great rigidity, which can make their installation in the grooves 3 and 4 painful, if not impossible. This difficulty can be overcome by creating in each hook an elastic deformation zone in the vicinity of the bridge 8 using, for example, a transverse opening allowing the easy widening of the slots 11 and 12.
  • Fig. 3 is a view of part of another embodiment of the connecting element 5, illustrating the solutions which make it possible to avoid the above problems.
  • this embodiment there is a bridge 18, similar to the bridge 8 but having a double thickness, this additional thickness being arranged so as to fill the space 15 visible in FIG. 2.
