Embodiment Construction

[0022] A large number of clockworks can be produced with a reduced number of components, preferably with components made of silicon, or by means of the LIGA or DRIE method, said clockworks comprising flexible regions.

[0023] These flexible areas can be used to form guides, in particular pivot guides, and / or to form elastic return means.

[0024] "Flexible guide" in the following description refers to a linear or rotational guide comprising one or more flexible bands. These guides have many advantages, among which the following should be mentioned: precision, no friction, no hysteresis, no wear, no need for lubrication, no sticking, one-piece manufacture. The most common limitations are: restricted movement, low return force or moment strength, occasionally complex dynamics, and limited loads to be carried.

[0025] The flexible guide can be modified to have zero stiffness or to have a bistable state with respect to a member that works by buckling under an applied force on e...

Abstract

The invention relates to a timepiece escapement (100) comprising an escape wheel (400) and a balance wheel (300) without a disc, formed by a flexible one-piece mechanism (500) in said shocks are transmitted between the balance wheel (300) and said escape wheel (400), said flexible one-piece mechanism (500) is connected by at least one flexible band (700) to a fixed structure (800) or to said escape Vertical wheels (400). The oscillations are maintained by a hairspring (121) terminating in a hairspring stud (122), which is movable during operation and is guided by a flexible guide with a flexible band (124) ( 123) guide, the center of rotation (125) of said flexible guide (123) is coaxial with said balance wheel (300), wherein said hairspring stud (122) receives a pin (127), which pin (127 ) is movable along the cam path (128) of the wheel (126). During oscillation, said balance spring stud (122) moves under the force exerted by said balance spring (121) relative to the rest position of said balance spring stud (122), and said pin (127) maintains and Adjust the oscillation.

Description

technical field [0001] The invention relates to a timepiece escapement comprising a fixed structure, an escape wheel, a balance wheel without discs and a flexible integral mechanism arranged between said balance wheel and said The flexible one-piece mechanism comprises at least one flexible band connecting the flexible one-piece mechanism to the fixed structure or to the escape wheel. [0002] The invention also relates to a timepiece movement comprising a fixing structure and at least one mechanism of this type. [0003] The invention also relates to a timepiece comprising a stationary structure and at least one mechanism of this type and / or at least one timepiece movement of this type. [0004] The present invention relates to the field of timepieces and more particularly of escapements. Background technique [0005] Watchmaking performance demands high-precision movements with minimal space requirements and a reduced number of parts in order to keep costs in production,...
