Abstract:
An unfolding clasp for a bracelet comprising: a profiled plate having two spaced-apart parallel branches defining a space for the assembly, in a freely articulating manner, of at least one blade having, on a side away from an articulating part of the at least one blade, provisions for articulated assembly of part of the bracelet, wherein the blade or blades of the bracelet are equipped, close to the part receiving the bracelet, with two rotating rollers placed coaxially with and protruding from each lateral side of the blade in order to cooperate with a profiled rim of an open recess formed laterally in the thickness by spaced lateral edges of each branch for the purpose of creating, after folding down of the blade, a snap-fastening effect by rolling friction resulting from tensioning of the blade, said recess being equipped with means for stopping the blade or blades in the snap-fastened position, wherein the means of stopping the blades in the snap-fastened position consists of transverse rollers assembled between the lateral edges of the recess, thereby acting as a spacer.
