The present invention relates to a direct escapement mechanism () having an escape wheel () provided with a series of peripheral teeth (), and an anchor (), having an entry-pallet () and an exit-pallet () each having a locking plane () and also having a fork (). It also comprises a pin () which can be rigidly connected to a regulating organ () to cooperate at each alternation of said regulating organ () with the fork () of the anchor in order to unlock at least partially said anchor from the escape wheel () as well as at least one impulse pallet () which can be rigidly connected to said regulating organ () to cooperate with a tooth () of the escape wheel to transmit a direct impulse to said regulating organ (). Typically, at least the teeth () of the escape wheel or one of the entry-pallets or exit-pallets () comprises in the extension of said locking plane () a inclined plane () arranged to provide an indirect impulse to said regulating organ () during a movement of said pallet in the path C of the escape wheel () by rotating the anchor () on its axis (X). The invention also relates to a timepiece incorporating such an escapement mechanism.

Escapement mechanism for timepiece

A direct impulse free escapement mechanism for a timepiece includes: an escapement wheel with peripheral teeth; a locking device including a locking pallet engaging an escapement wheel tooth in a locking position of the locking device; and a control pallet actuated by a pivoting regulating organ to engage a complementary unlocking organ of the locking device to release the locking device from the escapement wheel in an unlocking position at each alternation of the regulating organ. Also included are impulse pallets attachable to the regulating organ, cooperating on an impulse plane with a tooth of the escapement wheel to transmit a direct impulse to the regulating organ. The locking device is drawn by the escapement wheel in each locking position. The teeth of the escapement wheel and the impulse pallets are configured so the impulses occur outside the plane of the escapement wheel. A corresponding timepiece is also disclosed.

Free direct escapement mechanism for a timepiece

Disclosed is a device for securing and adjusting a bearing in an orifice in a bridge or a plate of a timepiece. It includes a first bearing screw defining a crimping opening of such a bearing and including an external thread, a second screw, so-called locking screw, defining an internal bore and including an external thread and a socket defining a tubular housing extending following a longitudinal axis, the tubular housing including a first tapped section, adapted to screw the first screw, and a second tapped section, adapted to screw the second screw. Advantageously, the external threads of the first and second screws and the corresponding sections of the socket have respective screwing pitches in opposite directions. Also disclosed is a method for securing and adjusting a bearing in an orifice provided for that purpose in a bridge or a plate of a timepiece thanks to such a device.

Device for securing and adjusting a bearing, especially for timepieces

Disclosed is an escapement mechanism with a locking anchor for a timepiece including a sprung-balance regulating organ, including an escapement wheel provided with a series of peripheral teeth, and a locking anchor including first and second locking pallets arranged respectively at one end of first and second arms to allow alternately engaging a tooth of the escapement wheel at each rotation step of the escapement wheel and of the anchor about their respective axis of rotation. This mechanism includes an impulse pallet adapted to be fixed to one the regulating organ to transmit an impulse by sliding a tooth of the escapement wheel on an impulse plane of the impulse pallet once at least every two oscillations of the regulating organ while the locking anchor includes a connecting member for permanent kinematic engagement in rotation to the regulating organ. Also disclosed is a timepiece incorporating such an escapement mechanism.

A timekeeping pivot linking a first part with a second part, pivotably about a pivot axis, the pivot comprising a blade having an edge, rigidly connected to one of the first or second parts and the median plane of which passing via the edge defines a blade plane, and a bearing area rigidly connected to the other of the first and second parts and against which the edge of the blade bears, the contact points of the blade and of the bearing area being substantially situated on the pivot axis, the first and second parts being rigidly connected in translation in the direction orthogonal to the pivot axis contained in the blade plane.

Flexural pivot

A drive system for energizing a device that includes a bellows actuated drive. The bellows actuated drive provides linear forward and backward movement by fluid expansion and contraction of a fluid within a reservoir according to a temperature differential while the reservoir is in fluid contact with the bellows. In one variant, two bellows are configured in a V shaped conformation. Various devices are driven using the drive system of the current invention and include a timepiece, a medical device, an implantable medical device, a cardiac rhythm management device, a hearing aid, a medical micro-injector, a sensor, and a biometric transmitter.
