Abstract:
1. An escapement mechanism for an oscillator structure having a fixed portion, and an oscillator that is pivotably attached to the fixed portion, comprising: a main wheel that is attachable to an external source of rotational energy; an impulse arm that is pivotably fixable in relation to the fixed portion of the oscillator structure, wherein the impulse arm is fixable in a reset position, wherein when in the reset position, the impulse arm has stored potential energy and is decoupled from the main wheel; and a trigger mechanism for releasing the impulse arm from the reset position; wherein in a first phase, the trigger mechanism is configured to release the impulse arm, such that the impulse arm falls and impulses the oscillator; and wherein in a second phase, the impulse arm is configured to continue to fall away after impulsing the oscillator to become detached from the oscillator, and to release the main wheel, which is configured to rotate in response to the rotational energy, and restore the impulse arm to the reset position.
