Definitions

  • the present invention relates to a flexible bracelet with links articulated.
  • the invention is very broad in application, since it can be used both in watchmaking as a wristwatch and in jewelry as a simple bracelet, as well as belt, curtain, etc.
  • the currently known metallic watch straps are consisting of links generally articulated to each other by transverse pins.
  • this articulation mode presents however the disadvantage of requiring a minimum thickness for links, greater than the diameter of the pins.
  • CH-A-614 360 describes a bracelet in which two links adjacent are hinged together by two balls each immobilized between two retaining means against which they bear.
  • the links have only one flange.
  • each link undergoes deformation transverse, which assumes, on the one hand, that the flanges are made in deformable materials without intrinsic elasticity and that the balls, on the other hand, are hard and not brittle to resist the compression.
  • the bracelet is no longer removable, which excludes any quick and simple after-sales service intervention to adjust its length or to replace a part.
  • this bracelet cannot include more than two balls. in the transverse direction by link because the assembly process by compression does not allow deformation of the flange on large widths with a large number of balls which constitute so many hard points.
  • this bracelet cannot be suitable for a watchmaking application because watch cases with the movement and their glass are too fragile to be able to undergo such transverse deformation.
  • the object of the invention is to provide a flexible bracelet whose articulation between links would be designed so as to be able make a bracelet of much smaller thickness, without harm the solidity of the whole and with all the advantages that aesthetically.
  • each link is articulated to an adjacent link by at least one first ball immobilized between two retaining means provided respectively on a first flange of said link and on a second flange of said adjacent link, and by at least one second ball immobilized between two retaining means provided respectively on a second flange of said link and a first flange of said adjacent link, the first and second flanges of the same link being maintained in a parallel configuration by assembly means.
  • said retaining means are circular cutouts against which said balls come in support.
  • said circular cutouts have a outside chamfer at the links.
  • one of said links have flanges between which is inserted a housing of shows, at least one of said flanges being pierced with an opening.
  • said assembly means are consisting of at least one spacer placed between the flanges of the links, and by a fixing screw passing through said spacer.
  • said balls are produced in one of the following materials: gold, silver, platinum, steel, fine stone, hard stone, synthetic, transparent or opaque stone and the links are made in one of the following materials: gold, silver, platinum, steel, brass.
  • the first and second flanges of the same link are held in a inverted or upside down configuration by respectively defining a frontal face and a dorsal face.
  • first and second flanges of the same link define lateral faces between which is arranged a central flange provided with retaining means in which said balls are supported.
  • the thickness of the flexible bracelet with articulated links according to the invention is essentially determined by the diameter balls ensuring the articulation between the links. This thickness can so be made as weak as you want, only considerations of mechanical strength limiting its reduction.
  • one of said links includes flanges between which is inserted a watch case, at least one of said flanges being pierced with an opening.
  • FIGS. 1a, 1b and 1c show, in plan views, from the side and in perspective, a flexible bracelet with articulated links in which a link 10 consists of a first flange 100 and a second flange 200, said flanges being maintained in a configuration antiparallel, or head to tail, by means of assembly.
  • said assembly means are formed by two spacers 301 placed between the flanges 100, 200 of the link 10 and by two fixing screws 302 passing through the spacers 301 respectively.
  • the flanges 100, 200 are flat and all identical. They are nested in each other according to two series respectively defining a front face and a parallel dorsal side.
  • Each flange 100, 200 consists of two side tabs 100b, 100c delimiting between them a U-shaped housing.
  • side legs 100b, 100c extend along the longitudinal axis of the flange 100 by a central tab 100a intended to engage in the U-shaped housing of the adjacent flange 101 of the same series.
  • the link 10 that is to say the flanges 100, 200 and the means 301, 302 of assembly, can be made of a precious metal: gold, silver, platinum or even steel or brass.
  • the link 10 is articulated to the adjacent link 12 by two first balls 122 immobilized respectively between two circular cutouts 120 formed in the first flange 100 of the link 10 and two cutouts equivalent circulars made on the second flange 202 of the adjacent link 12, and by a second ball 212 immobilized between a circular cutout 220 formed on the second flange 200 of the link 10 and an equivalent circular cutout on the first flange 102 of the adjacent link 12.
  • link lines are thus defined transverse between the contiguous links and between the two faces of the bracelet.
  • These connecting lines constitute as many axes of articulation which give the bracelet longitudinal flexibility allowing it to take enough curvature to adapt to body shapes diverse and varied.
  • the essential of the thickness of the bracelet of the invention is determined by the diameter articulation balls. Therefore, we can get bracelets very flat and flexible using small diameter balls.
  • Said articulation balls can be made of metal precious: gold, silver, platinum, or steel, as well as fine stone, hard stone, synthetic stone, transparent or opaque.
  • FIG 3 shows a possible variant of the flexible bracelet Figures 1a and 1b.
  • This variant more specifically intended for jewelry, is obtained by significantly reducing on each flange the metal connecting parts between the circular cutouts receiving the articulation balls.
  • the bracelet thus produced offers the advantage of good highlight the beads especially when they are made of stone.
  • the cutouts circulars 110, 210 and 120, 220 have chamfers 113, 213 and 123, 223, or grooves, outside the link 10, this so as to give visually a larger dimension to the balls and add to their enhancement.
  • the bracelet includes a special 10 'link of which the two flanges 100 ′, 200 ′ are the dimensions of a housing of shows, so that you can insert said housing between the two flanges.
  • One of said flanges 100 ′ is pierced with an opening 400 for the display of the dial of the case.
  • each link 10 consists of two flanges 100, 200 opposite, defining lateral faces which are maintained parallel by assembly means 301, 302.
  • Each link 10 is articulated to an adjacent link 11 by at least two sets of two balls 121, 211 and 122, 212.
  • Each ball such as for example the ball 121, is immobilized between two retaining means such as cavities or circular cutouts made respectively on one of the side flanges 100 of link 10 and on a central flange 500 arranged offset between two adjacent links 10, 11.
  • the central flange 500 is therefore only held in place by the support of balls in their respective slots.
  • the alignment of the two balls 121, 211 of the same set in a link 10 creates a joint with a diametrical axis which gives a longitudinal flexibility of the bracelet.
