Definitions

the invention relates to an escapement mechanism comprising a balance wheel and an escape wheel, comprising a one-piece flexible mechanism for transmitting pulses between an ellipse of said balance and teeth of said escape wheel.
the invention also relates to a watch movement comprising a fixed structure and at least one such mechanism.
the document EP 2,037,335 A2 ENZLER & VON GUNTEN describes a monoblock anchor, Swiss anchor type, with two arms each provided with a pallet, and having arms constituted by flexible blades connected to a structure and defining a fictitious pivot.
the document EP 1 967 919 A1 ETA SA describes a tangential pulse exhaust comprising a mobile ring frame, comprising vanes arranged to cooperate with teeth of an escape wheel located inside this ring.
the invention proposes to overcome the limitations of known architectures, by proposing compact mechanisms, of small thickness, and economic to produce.
the invention also relates to a watch movement comprising a fixed structure and at least one such mechanism.
the flexible guides can be modified to have a zero rigidity or to have a bistable state in the case of a component working in buckling under the action of forces exerted on both sides of an average direction, either side of which this component can occupy two different stable states.
the transmission of pulses between said at least one balance wheel 300 and said at least one escape wheel 400 is carried out by a one-piece flexible mechanism 500.
This one-piece flexible mechanism 500 comprises at least one probe 600 for cooperation with said at least one escape wheel 400 or respectively said at least one rocker 300.
This one-piece flexible mechanism 500 is connected by at least one flexible blade 700, or preferably by a plurality of flexible blades constituting elastic return means, to a fixed structure 800 of said timepiece 1000, or respectively to said at least one escape wheel 400.
the Figures 1 and 2 illustrate an escapement without anchor 140.
the rocker 141 comprises a plate with a pin 142.
the plate has two pins / stops 143 and 144.
An escape wheel 145 has a plurality of teeth 146.
Each tooth 146 is a locking mechanism intermittent, and comprises a rocker 147: each latch 147 comprises a rocker pin 148 guided by flexible blades 149. This anchor pin 148 can be actuated by a small lever 150. Each tooth 146 also comprises a pulse plane 151.
the escapement wheel mechanism is at two levels: a low level carries the rocker pins 148, and corresponds to the level at which the pins / stops 143 and 144 are disposed, while a high level carries the wheel structure 145 and the levers 150.
a ruby lift is dedicated to the pulse.
the special shape of the pins / stops 143 and 144 integral with the plate avoid gallop.
