Synchronous escapement for clockwork

摘要

#CMT# #/CMT# The wheel (1) has a toothed release wheel (4) including a movable gear (5) that includes a release tooth (6) and a locking tooth (8). The release tooth has a drive unit (11) arranged to cooperate with complementary drive unit (12) comprised in the locking tooth to drive the locking tooth in a radial direction (S2) when the release tooth is driven in the direction opposite to another radial direction (S1). The drive unit is arranged to move at a distance from the complementary drive unit, without driving the locking tooth when the release tooth is driven in the latter radial direction. #CMT# : #/CMT# The escape mechanism is is made of micro-machinable material, or silicon, or quartz or a silicon or quartz compound, or an alloy derived from microelectromechanical system (MEMS) technology, or an alloy obtained via the Deep reactive-ion etching (DRIE) or lithography, electroplating, and molding methods, or made of an partially amorphous material. An independent claim is also included for a timepiece movement comprising an escape mechanism. #CMT#USE : #/CMT# Escape wheel for escape mechanism i.e. detent escape mechanism, of a timepiece movement of a timepiece (all claimed) i.e. wristwatch. #CMT#ADVANTAGE : #/CMT# The design of the escape wheel offers high level precision for which a type of escapement is renowned and guarantees perfect alignments during movement. The wheel utilizes reduced number of components and minimum adjustments. The wheel is assembled in a simple manner. The wheel can be easily integrated in existing movements and offers considerable space saving, thus enabling other functionalities of the movement of the timepiece concerned to be housed in the middle part of the timepiece. The wheel offers potential improvement in efficiency, thus conserving power. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic partial perspective view of escape wheel seen from a side of release teeth and locking teeth.
