The invention relates to a timepiece component (1) that has an aperture (7) for receiving a support element (3) and includes a clamping system (13) for exerting radial force, enabling said timepiece component to be secured to said support element. According to the invention, the clamping system (13) includes a radial clamping device (15) that has a crown (6) for exerting said radial force and a concentric, blind recess (8) spaced apart from said aperture, to allow a travel for the crown. Moreover, the clamping system (13) further includes a device allowing a travel (17) that has a second, concentric, blind recess (10), spaced apart from said first blind recess (8), and located on the opposite surface to said first recess, to allow said crown a greater degree of freedom relative to said support element.The invention concerns the field of timepieces.

The tangential impulse escapement includes a lever device (1) including a lever (3) driving a roller (65) and a ring (7) surrounding an escapement wheel set (8), said ring being fitted with pallet-stones (9, 10, 11, 12) for cooperating with the teeth (13, 14, 15, 16) of said wheel set, in order, alternately, to lock the latter then import an impulse to said roller. The escapement wheel set includes at least first (17) and second (18) coaxial secured wheels. The pallet pallet-stones (9, 11, 12) of the ring cooperate with the teeth (13, 15, 16) of the first wheel (17) with the exception of one (10), which is arranged for cooperating with the teeth of the second wheel (18).

The mechanism includes, mounted to rotate freely on an arbour 6, a driving wheel (5) driven by an oscillating drive pinion (3) and a driven wheel (7) meshed with the first wheel set (1) of a kinematic chain and comprising a dome (11) for housing a coupling device (10) comprising at least one bent locking arm (12) one end (14) of which has a pivoting point (14a, 14b) on the driving wheel (5) and the other end (16) of which has a point of abutment (16a) against the inner wall (2) of the dome (11) of the driven wheel (7) via the action of a spring (20) integral with said arm (12). The pivoting point (14b) preferably moves along a cam (21).Application to automatic winding by an oscillating weight.
摘要:
The blocking member (6) or detent member of the escapement carries a follower (20) which ends in a beak (21) which cooperates with a small roller (23) comprising a notch (22). When the locking pallet-stone (7) of the blocking member releases itself from the teeth of escapement wheel (2), the beak (21) penetrates in the notch (22). The return of the pallet-stone (7) in the locking position is caused by a rising flank (25) of said notch, said rising flank being inclined such that the beak (21) is forced to follow and climb over said flank when the small roller (23) rotates. The arrangement allows the escapement to resist to shocks and consequently to omit the return spring acting on the blocking member.

The escapement includes a large plate 4 carrying a first finger 14 and a blocking member 6 carrying a second finger 11 and a locking pallet-stone 7. The first and second fingers 14 and 11 are shaped such that when the large plate 4 rotates in a first direction a, the first finger 14 drives the second 11 which moves around a first side 20 of said first finger to release the locking pallet-stone. Re-engagement occurs when the second finger 11 climbs over a vertical flank 25 of a notch 22 made in a small plate 23. When the large plate 4 rotates in a second direction b, opposite to the first, the first finger 14 drives the second finger 11 which moves around a second side 21, opposite to the first, of said first finger 14 to keep the locking pallet-stone 7 in the escapement wheel.
摘要:
An assembly of an axially extending member, made of a first material, in an aperture of a part, made of a second material having no plastic domain. The part includes pierced holes forming an elastic deformation mechanism distributed around the aperture thereof. Further, the member includes an elastically and plastically deformed, radially flared portion that radially grips a wall of the part surrounding the aperture by stressing the elastic deformation mechanism, so as to secure the assembly in a manner that is not destructive for the part. The assembly can be used in the field of timepieces.

A timepiece includes a first oscillator oscillating at a first frequency and connected by a first gear train to an energy source to display the time. The timepiece also includes a chronograph system including a second gear train connected to the first gear train via a coupling device for selectively measuring a time. The chronograph system further includes a second oscillator, which is connected to the second gear train and oscillates at a second frequency. Moreover, the second gear train is connected to the first gear train by an elastic coupling, in order to synchronize the rate of the two oscillators using the same energy source when the coupling device is in a coupled position.
