This unfolding clasp for a bracelet has a profiled plate ( 1 ) with two spaced-apart parallel branches ( 1 a ) and ( 1 b ) defining a space ( 1 c ) for the assembly, in a freely articulating manner. At least one blade ( 2-3 ) has, on the side away from its articulating part, provisions for the
This unfolding clasp for a bracelet has a profiled plate ( 1 ) with two spaced-apart parallel branches ( 1 a ) and ( 1 b ) defining a space ( 1 c ) for the assembly, in a freely articulating manner. At least one blade ( 2-3 ) 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 ( 2-3 ) of the bracelet are equipped, close to the part receiving the bracelet, with two rotating rollers ( 6-7 ) and ( 8-9 ) placed coaxially with and protruding from each lateral side of the blade ( 2-3 ) in order to cooperate with the profiled rim ( 1 d 1-1 d 2 ) and ( 1 e 1-1 e 2 ) of an open recess ( 1 d -1 e ) formed laterally in the thickness of each branch ( 1 a ) and ( 1 b ) for the purpose of creating, after folding down of the blade ( 2-3 ), a snap-fastening effect by rolling friction resulting from tensioning of the blade. This recess ( 1 d -1 e ) is equipped with means ( 12-13 ) capable of providing the stop for part of the blade or blades ( 2-3 ) in the snap-fastened position.

1. 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. 2. The clasp as claimed in claim 1, wherein said clasp has two opposed symmetrical blades articulated to each of the ends of the branches, the recess being formed substantially in a central part of said bracelet. 3. The clasp as claimed in claim 1, wherein said spacer rollers comprise rollers which are mutually parallel and parallel to the spindle of the rotating rollers of the bracelet. 4. The clasp as claimed in claim 1, wherein the ends of the blades away from their articulation to the branches have a profiled shape oriented at an angle above the rotating spacers rollers, thereby being capable of pressing on the spacer rollers, said shapes being arranged in a substantially contiguous manner in the snap-fastened position of the blades. 5. The clasp as claimed in claim 4, wherein the free ends of the profiled shapes are perforated transversely straight through the assembly, with articulation of the corresponding parts of the bracelet. 6. The clasp as claimed in claim 1, wherein the coaxial snap-fastening rollers are mounted so as to rotate on a common spindle with the capacity to be dismantled in order to adjust their diameter to the desired snap-fastening force. 7. The clasp as claimed in claim 1, wherein the spacer rollers consist of a tube placed between the lateral edges facing the recess, thereby being assembled on a hollow spindle engaged in the thickness of the branches, said spindle accommodating, at each of its ends, detachable means for translational locking. 8. The clasp as claimed in claim 1, wherein the assembly of the plate and of the blades is bent longitudinally. 9. An unfolding clasp for a bracelet comprising: a profiled plate having two spaced-apart parallel branches defining a space for 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, 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 coaxial snap-fastening rollers are mounted so as to rotate on a common spindle with the capacity to be dismantled in order to adjust their diameter to the desired snap-fastening force. 10. An unfolding clasp for a bracelet comprising: a profiled plate having two spaced-apart parallel branches defining a space for assembly, in a freely articulating manner, of at least one blade havi ng, on a free end away from an articulating part of the at least one blade provision for articulated assembly of part of the bracelet, wherein the blade or blades of the unfolding clasp are equipped on said free end two rotating transverse 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 of the blades or blades in the snap-fastened position. 11. The clasp as claimed in claim 10, wherein said clasp has two opposed symmetrical blades articulated to each of the ends of the branches, the recess being formed substantially in a central part of said branches. 12. The clasp as claimed in claim 10, wherein the means for stopping the blades in the snap-fastened position consist of transverse rollers assembled between the lateral edges of the recess, thereby acting as a spacer. 13. The clasp as claimed in claim 12, wherein said spacer rollers comprise two rollers which are mutually parallel and parallel to a spindle of the rotating rollers of the blades. 14. The clasp as claimed in claim 10, wherein the means for stopping the blades in the snap-fastened position consist of at least one transverse branch positioned substantially in a central part of the recess and formed directly during the manufacture of the profiled plate. 15. The clasp as claimed in claim 12, wherein the ends of the blades away from their articulation to the branches have a profiled shaped oriented at an angle above the rotating spacer rollers, thereby being capable of pressing on the spacer rollers, said shapes being arranged in a substantially contiguous manner in the snap-fastened position of the blades. 16. The clasp as claimed in claim 15, wherein the free ends of the profiled shapes are perforated transversely straight through the assembly, with articulation of the corresponding parts of the bracelet. 17. The clasp as claimed in claim 10, wherein the coaxial snap-fastening rollers are mounted so as to rotate on a common spindle with the capacity to be dismantled in order to adjust their diameter to the desired snap-fastening force. 18. The clasp as claimed in claim 12, wherein the spacer rollers consists of a tube placed between the lateral edges facing the recess, thereby being assembled on a hollow spindle engaged in the thickness of the branches, said spindle accommodating, at each of its ends, detachable means for translational locking. 19. The clasp as claimed in claim 10, wherein the assembly of the plate and of the blades is bent longitudinally.
