CONTROL MECHANISM WITH SECURELY REMOVABLE STEM Russian patent published in 2018 - IPC G04B3/12 G04B27/02 

FIELD: watches and other time measuring instruments.

SUBSTANCE: invention relates to a device for controlling mechanisms for clockwork mechanisms and clock mechanisms comprising said control mechanisms. Control mechanism (100) for clock mechanism, including, in a housing in main plate (1), control stem (10) that is movable in longitudinal direction (D) and including groove (11) cooperating with stud (20) comprised in pull-out piece (2) for actuating the pivoting of pull-out piece (2) on main plate (1), wherein this pull-out piece (2) is held in position by a jumper (3) spring, wherein mechanism (100) includes bridge (5) cooperating with main plate (1) to confine stem (10), wherein bridge (5) includes housing (54) in which there is movable limiter piston (6), arranged to abut on one end of trunnion (29) comprised in pull-out piece (2) under the application of a force in transverse direction (T), substantially orthogonal to longitudinal direction (D), to allow the release of stem (10) after given travel (C) of limiter piston (6).

EFFECT: technical result is an improvement in the design of the stem control mechanism.
