A bracelet having articulated links, including an articulation between a first link and a second link including a tongue that pivots in an opening between side flanges of this first link together forming a double clevis fitting, wherein, in the articulation, the first link or respectively the second link includes at least one external trunnion or respectively at least one internal trunnion arranged to pivot in an internal half-bearing of the second link, or respectively in an external half-bearing of the first link, the second link or respectively the first link includes at least an upper part and a lower part arranged to enclose and conceal therebetween each external trunnion or respectively each internal trunnion.

Articulated bracelet with hidden articulations

An item includes at least two sets of assembled elements that are connected to each other by a permanent securing device. The permanent securing device includes a pin mounted in a through hole of a central element of a set. This pin is mounted at each end in a blind recess of a side element belonging to another set. At one end, the pin is secured in the blind recess by a locking device, for example by a screw connection. At its other end, it is welded to a socket which is itself secured by a locking device in the blind recess of the side element.

Assembly of elements such as bracelet links

The invention relates to an assembly system including first and second parts each including a blind recess and at least one third part including a through hole. According to the invention, the assembly system further includes a permanent securing device including a pin mounted in the through hole of the at least one third part, the pin including, at a first end, a first means of locking one of the first and second parts in its blind recess, and a socket whose external wall includes a second means of locking the other of the first and second parts in its blind recess, and whose internal wall is welded to the second end of the pin in order to join the first, second and at least one third parts to each other with no plastic deformation of the first and second parts.

System of assembling at least three parts

Housing insert for a spacer of a ceramic link for a bracelet, including a housing for receiving a spacer having one end. It includes an external machined portion arranged to cooperate with this housing and an internal machined portion including a substantially cylindrical bearing area, arranged to closely receive this end and having a smaller diameter than that of this end. An equipped link includes such a link and such an insert of this type fixed in this housing. A bracelet including includes a plurality of equipped lateral links into which removably mounted spacers are driven. This bracelet includes intermediate links assembled to pivot freely relative to these spacers or relative to pins pivotably mounted in these equipped links.
