摘要:
The invention concerns an unfolding bracelet clasp, in particular a watch bracelet, formed of two strands (A) and (B), comprising a metal plate (10) whereof one end is coupled with an articulation (11) at the bracelet strand (A) free end and a lever (12) whereof the pin (13) is mounted at the plate (10) other end. Said lever (12) comprises a U-shaped part whereof the legs extend on each side of the bracelet forming at their ends hooks (18) designed to be urged in engagement, when the bracelet is closed, with the ends of a spring box axle (20) transversely housed in the bracelet strand (A) at some distance from the articulation (11) substantially equal to the plate (10) length. The length of the bracelet is adjusted by a dog point (19) engaged in a suitable hole of the bracelet strand (B).
摘要:
The invention concerns a bracelet comprising mutually connected links (1, 1', 1'') articulated through invisible pivot pins (2, 2', 2'', 2'''), the links are produced by moulding and the bracelet is mounted by mutually connecting the links by interlocking the pivot pins arranged on one of the links directly into the next link corresponding openings.

摘要:
Unfolding buckle-type clasp for a bracelet, comprising at least one branch (10, 12) and at least one arm (4) hinged by a first of its ends to a first end of the branch (4). Said branch (10, 12) has a side face (36, 38) disposed in relation to a side face (44, 46) of said arm (4) in the closed position of the clasp, and locking means for locking the clasp in its closed position, characterized in that the locking means include one or more resiliently deformable elements (56, 58) that extend, in the closed position of the clasp, into a housing (52, 54, fig. 3) formed on one hand by a longitudinal cavity (40, 42) in said side face (36, 38) of the branch (10, 12) and on the other hand by a longitudinal cavity (48, 50) in the side face (44, 46) of the arm (4).
摘要:
Une lunette tournante (18) est crochée sur une bague fixe (17) destinée à être fixée à la carrure de boîte. Cette lunette (18) comporte une denture (21) dans laquelle est engagée l'extrémité libre (22b) d'un ressort-fil de positionnement (22) dont l'autre extrémité (22a) est coudée et engagée dans un trou (23) de la bague fixe (17). Ce ressort-fil (22) comporte trois segments, deux segments d'extrémités (22c,22d) pratiquement droits et tangents à un cercle concentrique à la lunette (18) et un segment intermédiaire (22e) arqué avec son centre de courbure à l'intérieur de la lunette (18) mais de rayon sensiblement plus petit que celui de la lunette. La forme de ce ressort (22) permet de rendre les forces nécessaires pour faire tourner la lunette (18) dans les deux sens, pratiquement égales.
