Title
(EN) Elastic assembly, for example bracelet or ring
Abstract
(EN)

Extensible metal assembly, for example bracelet or ring, comprising link members (1) and connecting members (2). Each link member has at its center a cavity (3) which goes right through in the longitudinal direction of the bracelet. The side walls of said cavity have each two holes (4). The connecting member is formed by a flattened tubular envelope. In this envelope there is provided a spring (6) having four S-shaped arms. The ends of those arms form studs (5) which project by pairs on either side of the tube. The tube has a width slightly smaller than that of the cavity (3). The connecting member is arranged on the side of the cavity (3), in the same plan as the rigid element, and pushed into the cavity. Upon passing, two of the studs (5) slide against the edges (8), are retracted into the opening (7) of the tube, and expand into the holes (4), fixing the members together.
