Time zone on demand on the main hands of a timepiece
Abstract:
The invention concerns a mechanism (100) for displaying, on demand, the time in a time zone, on the hands of a timepiece.It is characterized in that it includes: two memory wheels (30), each including a heart-piece (40) that pivots relative to a toothed wheel (31) between indexing positions (34) thereon, with which it cooperates via a finger-piece (41) radially returned to said positions by a spring (43), support means (50), which, between two actions by the user, connectably cooperates with a support surface (45) of a memory wheel (30) and is then disconnected from a support surface (45) of the other memory wheel (30), a differential gear (12) with a first input formed by a motion work wheel set, a second input formed by a crown (12A) of said differential gear (12) with which each memory wheel (30) meshes, and an output consisting of an hour hand (25). The invention concerns a timepiece incorporating a mechanism (100) of this type.
Abstract(Chinese):

本发明涉及一种机构（100），用于根据需要显示在手表上的时区中的时间。 其特征在于，它包括：两个记忆轮（30），每个记忆轮（30）包括在其上的分度位置（34）之间相对于齿轮（31）枢转的心件（40），其经由手指 （41）通过弹簧（43）径向地返回到所述位置，支撑装置（50），其在使用者的两个动作之间与记忆轮（30）的支撑表面（45）可连接地协作，然后 与另一个记忆轮（30）的支撑表面（45）断开，具有由运动工作轮组形成的第一输入的差速齿轮（12），由所述差速齿轮的表冠（12A）形成的第二输入 12），每个记忆轮（30）啮合，以及由时针（25）组成的输出。 本发明涉及一种结合有这种机构（100）的钟表。
