The invention relates to a direct escapement mechanism (1) including an escape wheel (2) provided with a series of peripheral teeth (3), and pallets (4), including an entry pallet (10) and an exit pallet (11) each including a locking plane (10p, 11p) and also including a fork (43). It likewise includes a pin (6) capable of being rigidly connected to a regulating member (5) so as to engage, with each alternation of said regulating member (5), with the fork (43) of the pallets in order to at least partially separate said pallets from the escape wheel (2), as well as at least one impulse pallet (9) capable of being rigidly connected to said regulating member (5) so as to engage with a tooth (3) of the escape wheel in order to transmit a direct impulse to said regulating member (5). Characteristically, at least the teeth (3) of the escape wheel or one of the entry or exit pallets (11) includes, forming an extension with the locking plane (10p, 11p) thereof, an inclined plane (3i, 10i, 11i) arranged to provide an indirect impulse to said regulating member (5) during a movement of said pallet in the trajectory C of the escape wheel (3) by rotating the pallets (3) on the axis (X3) thereof. The invention likewise relates to a timepiece provided with such an escapement mechanism.

Abstract

An escapement mechanism (1) with a rest lever for a timepiece comprising a regulator component (2) of the balance-and-spring type, comprising an escapement wheel (3) provided with a series of peripheral teeth (31), and a rest lever (5) comprising a first and a second rest pallet (52, 53) respectively arranged at one end of a first and of a second arm and capable of alternately engaging a tooth of the escapement wheel (3) with every stepped rotation of the escapement wheel and of the lever about their respective axes of rotation. According to the invention, this mechanism comprises at least one impulse pallet (21, 22) which can be mounted on the regulator component (2) in order to transfer an impulse by sliding a tooth of the escapement wheel on an impulse plane (p) of said impulse pallet once in at least every two oscillations of said regulator component, whereas the rest lever comprises a member (51) for permanent rotational kinematic linking to said regulator component. The invention also relates to a timepiece comprising such an escapement mechanism.

Abstract

The invention relates to a direct-impulse free escapement mechanism (1) for a timepiece, having an escapement wheel (2) that extends in a plane PI and is provided with a set of peripheral teeth (3), a locking device (4) having at least one locking pallet (41) designed to cooperate in abutment with a tooth (3) of the escapement wheel (2) in at least one locking position of said locking device (4), and at least one control pallet (6) actuated by a pivoting regulator member (5) in order to cooperate with at least one complementary disengagement member (44) of the locking device (4) in order to disengage, on each alternation of said regulator member (5), the locking device (4) from the escapement wheel (2) into a disengaged position. The mechanism also has impulse pallets (9) that are able to be secured to said regulator member (5) in order to cooperate on an impulse plane with a tooth (3) of the escapement wheel (2) in order to transmit a direct impulse to said regulator member (5). According to the invention, the locking device (4) is designed to be pulled by the escapement wheel (2) into each locking position, and in that the teeth (3) of the escapement wheel (2) and the impulse pallets (9) are configured and designed such that the impulses occur outside the plane PI of the escapement wheel (2). The invention also relates to a timepiece provided with such an escapement mechanism.

Abstract

The invention relates to a device (1) for securing and adjusting a bearing (P) in an opening intended for this purpose in a bridge or bottom plate of a timepiece. It comprises a first screw (2), called bearing screw, which defines a setting opening (24) in said bearing (P) and having an outer thread (F1), a second screw (3), called locking screw, defining an inner bore (33) and having an outer thread F2 and a socket (4) defining a tubular housing (41) that extends in an longitudinal axis (A-A'), said tubular housing (41) comprising a first inner threaded portion (S1) designed for screwing- n the first screw (2), and a second inner threaded portion (S2) designed for screwing in the second screw (3). The outer thread (F1, F2) of the first and second screws (2, 3) and the corresponding portions (S1, S2) of the socket (4) advantageously have opposite screw pitches. The invention also relates to a method for securing and adjusting a bearing (P) in an opening intended for this purpose in a bridge or bottom plate of a timepiece by means of the above type of device.

Abstract

The invention relates to a free coup perdu escapement mechanism for a timepiece, comprising: - a wheel train, intended to be driven by a motor element and comprising a wheel train mobile (1) and an escapement wheel (2), rotating together about a respective axis of rotation, - an oscillator capable of receiving a pulse from the escapement wheel (2) in order to maintain the oscillations of same. This mechanism further comprises: - a disengagement mobile (7) designed to interact in rotation with the escapement wheel and to move, during a disengagement phase, under an oscillator pulse, between an engaged position in which the advance of the wheel train is blocked and a disengaged position in which the advance of the wheel train is free, and - a unidirectional drive device of the disengagement mobile (7) designed to transmit said oscillator pulse to the disengagement mobile (7) in order to cause it to pass from the engaged position to the disengaged position, in such a way that a portion of the energy supplied by an oscillator pulse during disengagement of the disengagement mobile (7), contributes to the acceleration of the wheel train.
