Definitions

the invention relates to a holding or supporting assembly of a clockwork spiral spring, comprising a stud and a stud holder, which stud holder comprises means for fixing said stud holder to an escape mechanism, and said stud having at least one orientation surface defining a direction of support or support of said spiral spring.
the invention also relates to a clock escapement mechanism comprising at least one such holding assembly.
the invention also relates to a watch movement comprising at least one such escape mechanism.
the invention also relates to a timepiece comprising at least one such movement.
the invention relates to the field of watch exhaust mechanisms.
the stud constituting the external attachment point of the spiral spring, is clipped on a bolt carrier which is a stamped flat piece.
the stud On high-end creations, the stud is screwed into a stud holder which is a machined component.
the fixing screw then works between his foot and his nets. The head is never blocked, resulting in regular breakages, following the torsional forces experienced when the foot is blocked on the peak, and when the operator continues to screw.
the invention proposes to provide a solution for maintaining the outer turn of the hairspring, which is compatible with high-end movements, and to solve the recurring problem of holding the screws by a screw-free fixing solution.
the invention relates to a holding or supporting assembly of a spiral clockwork spring, comprising a stud and a stud holder, which stud holder comprises means for fixing said stud holder to a mechanism exhaust, said peak having at least one orientation surface defining a direction of support or support of said spiral spring, characterized in that said bolt carrier is in two parts, and comprises a rigid structure carrying said fastening means, and a leaf-spring pressed against said rigid structure and comprising at least one elastic lip defining with said structure a receiving chamber of said pin and cooperating with said at least one orienting surface of said peak for maintaining said pin in indexed and blocking position.
said lateral bearing surface constitutes an orientation surface which defines a single direction of the outer end of said spiral spring.
the invention also relates to a clock escapement mechanism comprising at least one such holding assembly.
the invention also relates to a watch movement comprising at least one such escape mechanism.
the invention also relates to a timepiece comprising at least one such movement, characterized in that said piece is a watch.
the invention makes use of a fastening element comprising elastic return means to, firstly allow the introduction or the extraction of a bolt by exerting on him a certain effort, and secondly maintain this pin in the operating position in a single stop position
the invention thus relates to an assembly 20 for holding or supporting a spiral spring 21 of timepieces, comprising a stud 1 and a stud holder 2.
This stud holder 2 comprises means 6 for fixing the stud holder 2 to an escape mechanism 30, such as a rocker cock, as visible on the figure 1 .
the stud 1 comprises at least one lateral bearing surface 7 defining a direction of support or support of such a spiral spring 21,
this stud holder 2 is in at least two parts, and comprises a rigid structure 5 carrying fastening means 6, and a spring blade 8 pressed against this rigid structure 5.
This leaf spring 8 comprises at less an elastic lip 9 defining with the rigid structure 5 a receiving chamber 10 of the pin 1.
This elastic lip 9 cooperates with this at least one lateral bearing surface 7 of the pin 1, for maintaining the pin 1 in the indexed position and blocking.
the pin 1 is pinched between the elastic lip 9 of the leaf spring 8, and a notch 53 of the rigid structure 5, visible on the figure 2 .
the lateral bearing surface 7 constitutes an orientation surface which defines a single direction of the outer end of the spiral spring 21.
the leaf spring 8 illustrated in Figures 1, 2 and 3 is preferably sheet metal cut and folded, it does not require any other particular machining. It is inexpensive, which makes it possible to use, with the same carrying structure 31 of the exhaust mechanism 30, and with the same rigid structure 5, several spring blades 8 of different sizes to cooperate with so many models of pitons. different geometries.
the rigid structure 5 may, depending on its dimensioning, be machined, or also made by stamping in a thicker and more rigid material than the spring blade 8.
the figure 2 shows a first variant of constant thickness, very economical, which lends itself to such a stamped embodiment.
the figure 4 shows a second variant of rigid structure 5 on two levels, which is preferably machined.
the assembly of the holding assembly 20 according to the invention makes it possible to simplify the machining and the production of the bolt carrier, since it is no longer necessary, contrary to the prior art, to make a bore or a housing similar for receiving the stud 1, nor tapping to cooperate with a locking screw.
this at least one lateral bearing surface 7 is fitted to the stop surfaces 11, 12 to define a single position of the bolt 1 in the direction of the axis D of the spiral spring 21.
the stud 1 has no stopping surface, on at least one side in the direction D.
the rigid structure 5 and / or the leaf spring 8 comprises an introduction ramp 13, 14, for the tangential introduction (according to the arrow of the figure 1 ), or conversely the tangential extraction of the piton 1 between the rigid structure 5 and the leaf spring 8.
This simple or compound ramp facilitates this insertion in the chamber 10 against the elastic return force of the spring blade 8. The same is true for the extraction.
the pin 1 When the pin 1 is pressed against this ramp and the spring blade 8, it is easy to lift the elastic lip 9, to allow the pin to reach its position mounted in the chamber 10 delimited by a notch 15 forming a threshold. introduction or extraction.
the chamber 10 is located, on the side of the leaf spring 8, in a clearance 80 visible on the figure 3 , the pin 1 bearing on a rear face 93 of the elastic lip 9, and, on the side of the rigid structure 5, in a notch 53.
This notch 53 is delimited on the one hand by an input sector, of preferably radiated, constituting such a ramp 13, and secondly by a flat 51.
This plate 51 may, according to the embodiment chosen, or remain at a distance from the elastic lip 9, or, as illustrated in FIG. figure 3 , bear in support a portion 94 of the elastic lip 9, only one end 95 cantilevered cooperating in support with the pin 1.
Other variants are conceivable without departing from the invention, which consists in pinching the pin between a rigid structure and an elastic spring blade.
the chamber 10 is designed, in all variants, to immobilize the stud 1 in a single position in projection in a plane perpendicular to the axis D.
the rigid structure 5 and / or the leaf spring 8 comprises a notch 15 at the chamber 10, corresponding to the threshold of introduction or extraction.
the rigid structure 5 comprises a notch 17 (or a slot, or the like) or a pin arranged to cooperate with a lug 18 or respectively a notch that comprises the spring-blade 8, to rigidly rotate the rigid structure 5 and the leaf-spring 8 pressed one on the other.
the leaf spring may also comprise at least three tabs bent at 90 ° as the elastic blade 9, and located on a bore 81 or a peripheral rim 82 of the leaf spring 8, arranged to cooperate with a bore 58 or a peripheral rim 59 of the rigid structure 5, to ensure their perfectly coaxial assembly.
the rigid structure 5 is of substantially annular shape for maintaining it resting on a structure 31, in particular a rocker arm, of the escapement mechanism 30, around the axis D of the spiral spring 21.
the leaf spring 8 is substantially annular in shape for its support in abutment between such a structure 31 and the rigid structure 5, or in support of the rigid structure 5 over their entire common periphery, around the axis D of the coil spring 21.
the rigid structure is mounted on the structure 31 so as to trap the leaf spring 8.
the rigid structure 5 comprises at least one face 51, 52, perpendicular to the axis D of said spiral spring 21, and preferably this rigid structure 5 comprises two faces 51, 52 parallel to each other and perpendicular to the axis D of the spiral spring 21.
the invention also relates to a clock escapement mechanism comprising at least one such holding assembly 20.
the invention also relates to a watch movement 40 comprising at least one such exhaust mechanism 30.
