Abstract
This unfolding clasp for a bracelet has a profiled plate ( ) with two spaced-apart parallel branches ( ) and ( ) defining a space ( ) for the assembly, in a freely articulating manner. At least one blade ( ) has, on the side away from its articulating part, provisions for the articulated assembly of part of the bracelet. This structure is important because the blade or blades ( ) of the bracelet are equipped, close to the part receiving the bracelet, with two rotating rollers ( ) and ( ) placed coaxially with and protruding from each lateral side of the blade ( ) in order to cooperate with the profiled rim ( ) and ( ) of an open recess ( ) formed laterally in the thickness of each branch ( ) and ( ) for the purpose of creating, after folding down of the blade ( ), a snap-fastening effect by rolling friction resulting from tensioning of the blade. This recess ( ) is equipped with means ( ) capable of providing the stop for part of the blade or blades ( ) in the snap-fastened position.
