AI Technical Summary

Technical Problem

Existing control devices with two parallel rods connected by a transmission block are incompatible with pushers integrated into the crown, preventing the rocker arm from being positioned at the periphery of the movement, thus inhibiting the actuation of additional functions such as starting, stopping, and resetting a chronograph.

Method used

A control device with a first and second rod connected by a transmission block, featuring a frame with a gear train and a rocker arm, allowing the integration of a pusher that actuates the mechanism via a coaxial tube, enabling the rocker arm to pivot and control the chronograph functions.

Benefits of technology

Enables the integration of a pusher into a control device with parallel rods, allowing actuation of additional watch functions like starting, stopping, and resetting a chronograph, while maintaining intuitive operation and aesthetic versatility.

Abstract

The present invention relates to a control device (10) for a timepiece, including a first stem (12) extending along a first axis, an actuator (14) secured to the first stem (12), a second stem (22) extending along a second axis parallel to the first axis, and a transmission block (30) connecting the first and second stems (12, 22). The transmission block comprises a frame (32, 40) and a gear train (46, 47, 48) mounted in the frame and kinematically connecting the first stem (12) to the second stem (22). The control device (10) further includes a pusher (18) associated with the actuator (14) as well as a control member (13) connected to the pusher (18) and configured to move along the first stem (12) when the pusher (18) is actuated. The transmission block (30) is further associated with a rocker (50) arranged to cooperate with the control member (13) and configured to control at least one mechanism of the timepiece.
