A mechanical regulator for horology including an escapement collaborating with an oscillator provided with an inertial element oscillating in an oscillation plane by virtue of a return element. The escapement includes a pin rigidly connected to the inertial element, an anchor including a fork collaborating with the pin, and two pallet stones collaborating with teeth of an escape wheel. The regulator is configured such that, during a first frictional locking phase that occurs before an unlocking phase, and during a second frictional locking phase that occurs after an impulse phase, the pin is in contact with the fork so as to push same, and a tooth of the escape wheel is in rubbing contact with one of the pallet stones.

Mechanical regulator for horology comprising a semi-detached self-starting escapement with low lift angle

The mechanical timepiece regulator of the invention comprises a flexure bearing oscillator and a double detent escapement, the oscillator comprising a balance wheel () connected to an elastic suspension () arranged to guide and apply a restoring force to the balance wheel () in a plane of oscillation. The escapement comprises an escape wheel () and an anchor () integrated into the balance wheel () and having two arms () arranged to receive alternately the impulses of the escape wheel (). The escapement furthermore comprises two detents () alternately locking the escape wheel () between two impulses and interacting with the arms () of the anchor to release the escape wheel () before each impulse, without direct interaction between the anchor and the escape wheel.

Mechanical timepiece regulator

An escapement mechanism for a timepiece, includes an escapement wheel (), an escapement anchor () including a body (), and a fork (), the body () including pallets (') that engage with the escapement wheel (), the body () having a shape that makes it possible to delimit an internal space () for arranging the escapement wheel (), the pallets (&#x2032;) including two rest pallets (&#x2032;) and two impulse pallets (&#x2032;), protruding in the internal space (). The mechanism includes a pin () of a roller () that is secured to a regulating device, characterized in that the roller () and the fork () are arranged with respect to one another such as to impart an alternating translation movement with respect to the escapement wheel () to the anchor () when the pin () engages with the fork ().
