Pallet lever for a timepiece escapement mechanism

摘要

An intermittent blocking mechanism for at least one escape wheel, that intermittent blocking mechanism cooperating with at least one regulating member or a balance which is actuated with an alternate motion under action of an elastic return mechanism, the intermittent blocking mechanism being pivoted in at least one bottom plate, and forming an inseparable single-piece component with the bottom plate. The intermittent blocking mechanism includes at least one pallet lever in a single-piece with the plate to which it is connected by the elastic return mechanism.

1. A timepiece assembly comprising:
a bottom plate; and a mechanism for intermittent blocking of at least one escape wheel; the intermittent blocking mechanism cooperating with at least one regulating member or a balance which is configured to be actuated with an alternate motion under action of at least one balance spring or an alternate elastic return means, the intermittent blocking mechanism being configured to be pivoted in at least the bottom plate, wherein the intermittent blocking mechanism forms an inseparable one-piece component with the bottom plate, which also forms a one-piece component with a first bearing for the escape wheel and with a second pivot bearing for the regulating member or of the balance, the first bearing and the second bearing being remote from each other with a fixed distance between centers thereof, and the intermittent blocking mechanism pivoting about a virtual axis whose theoretical position is defined with reference to positions of the first bearing and the second bearing, wherein the inseparable one-piece component includes a position adjustable mechanism including a rigid structure carrying, via a least one elastic strip, a position adjustable component including indexing means arranged to cooperate with complementary indexing means comprised in an adjustment mechanism, the complementary indexing means being detachably mounted to the indexing means and being blockable in a position of cooperation by a blocking mechanism elastically fixed to the structure, the blocking mechanism being in turn subjected to action of a locking mechanism which allows the blocking mechanism to occupy either an uncoupled position in which the adjustment mechanism is free, or a coupled position in which the blocking mechanism hinders the adjustment mechanism, the locking mechanism also being elastically fixed to the structure.
