Single piece coaxial escapement mobile for timepiece, has teeth formed at periphery of plates and cooperating with series of pallets, where plates are in integral form so as to reduce alignment problems of plates relative to each other

摘要

The mobile (100) has a tooth (108) formed at a periphery of a plate (103) and arranged to cooperate with a pin and a series of pallets. Another tooth (118) is formed at a periphery of another plate (113) and arranged to cooperate with another series of pallets. The plates are in integral form in order to reduce alignment problems of the plates relative to each other. The plates are formed by hubs (102, 112) connected to the teeth by arms (106, 116). One of the plates has an opening (104) to cooperate with a shaft so as to rotatably mount the mobile. An independent claim is also included for a coaxial escapement system for a timepiece.
