Embodiment Construction

[0040] exist figure 1 Among them, a timepiece movement according to one embodiment of the present invention includes a barrel 1 whose motor mechanism (not shown) such as a balance spring generates torque, and due to this torque, the motor mechanism Parts drive the running wheel train 2. This running train 2 itself drives the escapement mobile 3 , which forms part of an escapement 4 which also includes a pawl fork 5 . This pawl fork 5 is supported by the balance 6 of the mechanical oscillator 7 .

[0041] Another type of plate (not shown) or frame supports the barrel 1 , the escapement mobile 3 , the mechanical oscillator 7 and the running train 2 , the movement of which can be via rods or bridges (also not shown ) remain in place in a manner known per se. The escapement mobile 3 includes a pinion 8 meshing with a wheel of the running train 2 .

[0042] exist figure 2 , the escapement 4 and the mechanical oscillator 7 are united so as to form together figure 1 Mechanism ...

Abstract

The invention relates to a mechanism for adjusting an average speed in a clock movement, which comprises an escapement wheel (4) and a mechanical oscillator (7), in which a plurality of blades (23a, 23b), which are resiliently flexible in an oscillation plane, support and return a pendulum (6) so that said pendulum (6) oscillates at an angle in the oscillation plane. A pallet assembly (5) comprises two rigid pallets (13, 14) which are rigidly connected to the pendulum (6) and arranged to engage alternately with gear teeth (12) of the escapement wheel (11) when the pendulum (6) oscillates at anangle.

Description

technical field [0001] The invention relates to the field of mechanical watchmaking. More specifically, the invention relates to a mechanism for regulating the average speed in a timepiece movement and to a timepiece movement. Background technique [0002] In a timepiece movement, a motor element such as a mainspring provides the drive energy, and a running wheel train transmits the drive energy to the escape wheel of the escapement interacting with a mechanical oscillator. The speeds of the gears in the running train are all proportional to the speed of rotation, which is the average speed of rotation of the escape wheel. The average rotational speed of this escape wheel is determined by the oscillations of a mechanical oscillator. More precisely, the function of the mechanical oscillator is to provide a rate at which the angular pitches of the escape wheel follow each other. This rate must be as stable as possible. [0003] In Swiss patent application CH 709 291 (also ...
